UNDERGROUND MINES

Technological Field:

The invention relates to an air door which controls the air flow (contained oxygen and other gases) to be used in the underground mines and relevant surface and underground enterprises such as metro station, underground parks, malls, buildings etc.

State of the Art:

In the galleries of underground mines, air doors which air doors which is use in the all galleries. These doors in directing the air perform their functions by means of opening and closing like a normal house door. The adjustable air doors are the doors which have a window called regulator on them. The window opening (sectional area) can be changed with a sliding cover. The regulator, which is placed in the gallery, increases the resistance of the gallery with the window opening. So that, the amount of air passing through this arm is decreased, the amount of air passing through the other parallel arm is increased. The air doors which are currently used are either completely open or completely closed. These doors are fully used by means of a worker. If there is no worker, these doors cannot be operated in anyway. In other words, these doors are operated by human power. In other words, these doors are operated by human power.

Recently, the doors which are opened and closed hydraulically are use. On the other hand, in case of an emergency, it is required from a worker to go to the door and to open or close it for the air guidance by means of these doors, but it is not possible during the chaos of the emergency. Since these doors are generally made of wood, they have risk of burning. It is used in doors made of steel however these steel doors are very bulky and heavy. Successive 4 air doors are made in order to direct the air in a gallery healthily and to decrease the required pressure. Passing materials from here becomes a big problem. In addition to this, large and heavy equipment are transported in the underground by means of vehicles called MONORAY or COOLIE CAR. Transportation of this equipment is a major problem where these doors are present. When the operators driving the transportation vehicles come to these air doors, they stop the transportation vehicle, they get out of the vehicle, they open the door, they get on the car, they stop the vehicle after they pass the door, they get out of the car, they close the open door and then they get on the car again and they continue transport work. If there are successive air doors and they either perform this process successively or open all air doors, make the transportation process and then close all air doors and continue transportation work. Meanwhile, sometimes the doors are left open. Another solution is that, an assistant is present in the transportation vehicle. While this assistant performs opening - closing the air doors, the transportation vehicle operator realize the transportation work.

These doors create problem in creating the required resistance for the air guidance when they are fully open, as well as it allows uncontrolled air circulation. In case it is fully closed, the airway is also closed and air guidance cannot be provided. Although the doors which are urrently used are completely closed, sometimes air leakages may occur and thus this increase the ventilation costs. The required air flow with the currently used air doors is provided by means of windows called regulator which are opened on the door. Since these doors are made of wood, the windows opened on these doors cannot protect their sizes due to mining operations. In addition these doors are not configured to allow automation. In the patent document No CN203796305 (U) seen in the literature research made, an air door used in the mining sector is described. A conventional type door is disclosed. It consists of a mechanism for automatic opening and closing of the door for guiding the air. It is not possible to guide the air in the required amount. This door is defined as a door which can be opened and closed. In the patent document No CN207701162 (U) seen in the literature research made, a foldable air door to be used in the underground mines is disclosed. A foldable door model is developed in this invention in order to facilitate the transportation; there is no structure which allows more or less direction of the air.

The invention No CN205778981 (U) seen in the literature research made describes a system which controls the ventilation/wind doors to be used in the underground enterprises. The system provides an automatic opening - closing mechanism. When it is opened, it allows air flow, when it is closed, it cuts the air flow. It is not possible to provide a desired amount of air flow. The invention No CN 103670480 (A) seen in the literature research made describes an adjustable air window to be used in the underground mines. The invention described here is a small window which is located on the door rather than a door. It can be opened and closed automatically. Consequently, an air door is required to be developed in which the state of the art is exceeded, the disadvantages are eliminated.

Description of the Invention:

In this detailed description, the inventive air door (1) is described by means of examples only for clarifying the subject matter such that no limiting effect is created. In the description an air door (1), to be used in the underground mines and similar enterprises, for sending required amount of air in the required area in the underground mine when there is no transportation, for providing easy direction of the air by increasing the strength of the airway, for creating a sectional area to be used for transportation by means of moving on each other when there is transportation is disclosed.

Figure - 1 is a front view of the inventive air door (1). Accordingly, the air door (1) consists of many wings (12) which are formed by arranging at least one or more frames (11) side by side, create sectional area that is appropriate for the air flow by moving in the center of the frame (11) by 0 - 180°. The air door (1) can included a desired number of frames (11) according to the region it is used and the required air amount. Said frames (11) have a hinge mechanism which allows opening thereof with 45 - 90° as in the conventional doors. The frames (11) can move over each other in a sliding/overlaying manner, can provide the required sectional area fir maximizing the air flow and can create passage gaps specific to the situations such as transportation. If the air door (1) is a normal vent door, it consists of two frames (11) and will be produced such that the door can be opened and closed 45 - 90 degree back and forth. Thus it is possible to pass to the other side of the air door (1) when necessary. If the air door (1) is required to be mounted in a gallery where large equipment will be transported, in this case, the door will be produced such that it comprises a mechanism that can slide over each other. In Figure 2, a side view of the frame (11) of the inventive air door (1) is given. The wings (12) are in half open position in the side view. It allows air flow, but it creates some resistance. Here the gaps of the wings are adjusted at the desired angle, air as much as required can be transferred to the production area. They are placed in the frame (11) by means of the shafts (13) transversely. However, the wings (12) can be located in the frame (11) longitudinally. In Figure 3, a perspective view of the air door (1) is given. The position of the wings (12) which are located on the air door (1) can be seen more clearly in the perspective view. In Figure 4, an alternative in which the inventive air door (1) comprises a mechanism which can slide on top of each other in order to be appropriate for the galleries where large equipment will be transported. Accordingly, the air door (1) comprises a casing (10) wherein the frames (11) are located. There is a slider (14) on the inner wall of the casing (10), which allow the frames (11) to slide over each other. Therefore, a suitable gap (B) is provided for the passage of the transportation vehicles. At the same time, the amount of required section for the air flow is maximized.

In Figure 5, a representative view of an alternative of the inventive air door (1) which can be remotely controlled. Accordingly, the air door (1) comprises many wing motors (16) on side surfaces of the casing (10), which are in connection with the shafts (13) providing the assembly of the wings (12) to the frame (11) and rotation thereof. The number or wing motor (16) is as much as the number of the wings (12) located on the air door (1). At the same time, the slider motor (15) which is located on any section of the casing (10) and is engaged with the frames (11) allow for sliding the frames (11) on each other or in front of each other by moving then on the slider (14). Here, the slider motor (15) and the wing motor (16) is included in an automation circuit and drive and control system is provided. However, if the air door (1) is required to be controlled form a remote point in the underground, this condition can be provided by means of a hydraulic drive mechanism (18). If the operator or the personnel requires, he/she can be able to control the slider motor (15) and the wing motor (16) located on the air door (1) by means of a control (17).

The underground mines are the enterprises which can be developed and downsized. In the following years, the requirements may change depending on the situations to be taken by the underground enterprise. It is difficult to change the geometry in the air door which is currently applied. It is possible to respond to the requirements by only changing the angle of the wings (12) with the invention. Since the wings (12) can be opened and closed on each other, they can also be opened and closed in opposite directions to each other. Also, the wings can be mounted to the frame (11) from the center and thus they can be angled, they can be mounted to the frame (11) from the lower and upper points and they can perform different functions for different purposes.
