DRAINING VEHICLE OF WATER. SNOW OR/AND HAIL FROM
ATHLETIC GROUNDS
The invention refers to a vehicle which pumps water from athletic grounds (e.x. fields) and includes, except for the usual sub-systems of a vehicle, a pumping mechanism of water, a container for gathering water and a system of channelling the collected water.
With the appropriate modifications, this vehicle can also remove snow or/and hail from these grounds.
The existence of a similar vehicle for draining water and removing snow or/and hail from athletic grounds is not known. Up to this day, the confrontation of a flooded athletic ground after a very hard rainfall during a game (e.x. football match) is dealt with by the personnel of the field with off-handed means (e.x. brooms, wipers e.t.c), and as a result the surface is damaged (e.x. of the sod) there is a significant delay in the holding of the match and most of the times, the postponement of the game due to the ineffectiveness of the above method. This kind of practice is equivalently ineffective even when the sporting ground is covered with snow or hail has dropped.
The advantage of the invention is the immediate (in a very short period of time) restoration of the use of an athletic ground after a very intense rainfall, snowfall or/and hailstorm.
This is very significant, since it is widely known that after such weather conditions during athletic games (e.x. football matches) the match can be interrupted and delayed or even postponed.
Furthermore, with the present invention the damage of the surface is avoided (e.x. sod), because of lack of friction by the means used nowadays.
Finally, the use of the invention requires few personnel.
The invention - with some of its variations - is presented further on in detail, with reference to the attached figures. It is emphasized that the figures have not been done by scale and operate additionally to facilitate the understanding of the invention. Their aim is to the show the schematic arrangement of the components of the invention, but no their relative dimensions nor their precise position on the vehicle. In any case, the applied protection is specified by the claims.
Figure 1 : Depicts the vehicle at a side view, with the pumping mechanism of water, the container for gathering it and the channelling system.
Figure 2: Just as Figure 1 , with the difference that, before the water collection container there is an intermediary container added for "partitioning" the air suction from the water. The water is transferred to the collection container with a pump.
Figure 3: Variation for removal of hail, as well. Just as Figure 1 , with the difference that right behind the nozzle holder of the water suction there is a "rake" added for sweeping the ground and collecting the hailstones. It is obvious that the rake can be also added to the variation of Figure 2. Figure 4: Variation for removal of hail, as well. Just as Figure 2, with the difference that on the nozzle holder of the water suction (at the back of it) a "rake" has been added for sweeping the ground and collecting the hailstones. It is obvious that the nozzle holder of the suction with the embodied rake can also be added to the variation of Figure 1.
Figure 5: Variation for removal of snow, as well. Just as Figure 1 , with the difference that in front of nozzle holder of the water suction hot air is adduced to melt the snow. The adduced air is heated with electrical resistors. It is obvious that the system of adducing hot air can be added to the variations of Figures 2,3 and 4.
Figure 6: Depicts the additional "rake" for sweeping the ground and collecting the hailstones at frontage.

Bearing in mind, the lawn mower in big parks, as well as the vehicle for cleaningroads with brushes, with the modification of various mechanical parts of those or/and the alternation of their use, adding the pumping system of water and the collection of snow or/and hail it occurs.
The alternation e.x. on the lawn mower concerns the change of the blades that cut the grass and their replacement of at least one nozzle holder suction(2). Adding also a turbine (air pump) (1) for the creation of vacuum, one or more filters (6) and a piping system (5) for the transferring of the pumped water into the water collection container(7).
The water collection container(7) provides a system of channeling the collected water (8,17), for its emptying.
The specific realization of the invention is depicted in Figure 1 (and repeated in Figures 3 and 5).
The nozzle holder for water suction(2) is designed in order to follow the roughness of the ground, remaining at a fixed, small distance with the support of the wheels (3), which operate as defectors. The wheels have suspensions (4) (springs or/and shock absorbers), so that the nozzle holder (2) can follow the unevenness of the ground. Thanks to the existence of the wheel-defectors (3), the hopper (2) doesn't rub onto the surface of the ground and consequently doesn't cause attritions e.x. sod.
The operation of the vehicle concerning the water suction is as follows:
The turbine (air pump) (1 ) is turned on, so vacuum is created. In that way, the nozzle holder (2) draws air, the current of which is quite strong as to sweep along the rain water and lead them through pipes (5) to the collection container (7).
In this container there is an expansion system of the air towards the environment (9), whereas opposingly the water "is trapped" and remains in the container.
When the container (7) is filled, it can be emptied by the channeling system, which can be just a hole at bottom of the container (closed with a stopper or valve(8)) and a channeling pipe(17).
A variation of the invention, which is depicted in Figure 2 (but in 4 as well), is composed as follows:
The container "partitioning" the air from the water can become the intermediary container (10), from which the water next will be driven - with the help of the pump (11 ) - to the final water collection container (7).
For the gathering of hail, the vehicle beholds additionally at the bottom side, a "rake" (12), which pushes the hailstones as the vehicle is sweeping the surface at the athletic ground and brings them to the spout of the nozzle holder(2),so that they can be sucked easier.
The rake (12) can be placed near the nozzle holder(2) just behind it (see Figure 3, 5). It can also be embodied in the nozzle holder (2), so that the nozzle holder "sweeps" the surface of the athletic ground and sucks at the same time (the hail with the water, see Figure 4). The rake (12) on its own is depicted at frontage in Figure 6, whereas the rake (12) embodied in the nozzle holder suction (2) is depicted in Figure 7.
For the snow gathering, its melting is suggested and after that its suction in the form of water, materialization of which is depicted in Figure 5. For the melting a system of electrical resistors (15) is used, which heatens air. The hot air is adduced with the help of one or more fans (14) and air pipes (16) on the snow surface, speeding up its melting procedure. The melted snow is sucked by the nozzle holder suction (2).
Finally, as far as the collection container (7) is concerned, this can be placed either on the vehicle itself or on a trailer. In the second case, (not depicted in the Figures), it is advisable for a quick attachment - detachment system of the vehicle from the trailer to exist, so that the full collection container (7) can be replaced in no time by another empty container.
