Description:
A TRANSFORMING SYSTEM PROVIDING ELECTRICITY GENERATION FROM

VIBRATION

TECHNICAL FIELD

The present invention relates to a transforming system which provides electricity generation from vibration which occurs in rail vehicles, presses, cutting machines, printing machines and similar structures.

KNOWN STATE OF THE ART

Energy recovery becomes more important since energy becomes more important from day to day. Different structures are provided for recovery of energy and these structures are continuously improved. One of the methods applied for energy recovery is to recover the energy which occurs by means vibrations which result from loads.

Vibrations occur in structures like rail vehicles, presses, cutting machines, printing machines, textile machines, etc. as a result of application of loads. Electricity is generated from these vibrations by means of various methods. In the present art, the systems which dampen vibration and which generate electricity are essentially piezo-electric based. Although efficiencies of piezo-electric systems are high, output powers of piezo-electric systems are low since the force limits they can endure is low. Moreover, piezo- electric crystals are expensive materials.

For instance, in the application with number TR2016/19138, an embodiment has been provided which realizes electricity generation by means of the vibration of vehicle motors. The invention generates electrical energy from vibration by means of piezo-electric material. However, the force limit which said invention can endure is low.

Besides piezo-electric-based systems, there are mechanical-impact dampening systems. However, when these embodiments operate at high speeds, their lifetimes are short. Besides, they cannot operate under high loads. For instance, in the application with number TR2014/00123, a hydro-mechanical system which generates electricity is provided. Said system has been assembled onto a panel and comprises an alternator which generates electricity, a hydraulic motor which provides rotational movement to the alternator, double- effect cylinders which transfer the oil to the hydraulic motor in a pressurized manner, double piston armed double-effect cylinder which provides movement to the double-effect cylinders, lever jack which provides movement to the double piston armed double-effect cylinder, lever jack arm which provides movement to lever jack and whose length can be changed, chain geared/belt pulley which provides movement to the lever jack arm whose length can be changed, charged electrical motor which provides movement to the chain gear, hydraulic tank which stores hydraulic oil. However, the force which can be endured by said system is low, and the lifetime of the system is short when the system operates at high speeds.

As a result, because of all of the abovementioned problems, an improvement is required in the related technical field.

DETAILED DESCRIPTION OF THE INVENTION

In this detailed description, the subject matter transforming system (100) which provides electricity generation from vibration is explained with references to examples without forming any restrictive effect only in order to make the subject more understandable.

In Figure 1 , a representative perspective view of the form of the subject matter transforming system (100) associated with the vibration source (1) is given. The present invention relates to a transforming system (100) which provides generation of electricity from vibration which occurs in rail vehicles, presses, cutting machines, printing machines and similar structures. In said transforming system (100), there is a transfer unit (60) configured to transform the vibration, obtained from a vibration source (1), into linear movement. There is a connecting rod (50) connected by means of at least one hinge (63) from a first end (51) part by means of the transfer unit (60) and which provides transfer of force coming from said transfer unit (60). There is a crank arm (40) connected to a second end (52) part of said connecting rod (50) by means of a connection pin (70). Said crank arm (40) is associated with a unidirectional clutch (30) by means of a crank shaft (80). Said unidirectional clutch (30) transforms the oscillation movement of the crank arm (40) into continuous rotation movement. There is the inertia disc (20) which is associated with the outer part of the unidirectional clutch (30) and which stores the mechanical energy applied periodically and which transfers said energy as constant mechanical energy. There is an alternator (10) connected to said inertia disc (20) and which transforms the mechanical energy, accumulated in the inertia disc (20) resulting from the continuous rotational movement, into electrical energy. In Figure 5, a representative zoomed view of the transfer unit (60) provided in the subject matter transforming system (100) is given. In said transfer unit (60), there is housing body (66) associated with the vibration source (1). There is a base plate (61) positioned in a housing (65) provided in said housing body (66). There is a piston arm (62) connected to said base plate (61) from one end and connected to said first end (51) of said connecting rod (50) by means of said hinge (63) from the other end. There is an opening (64) on the housing body (66) in order for said piston arm (62) to extend outwardly from the housing (65). Moreover, said opening (64) provided on the housing body (66) has a dimension providing movement of the base plate (61) inside the housing (65) in order to prevent movement transfer outside of an orthogonal axis (I) of the piston arm (62). A friction preventer (67) is provided between the vibration source (1) and the base plate (61) in order to prevent friction between the vibration source (1) and the base plate (61). Said friction preventer (67) can be oil or ball. Thanks to the transfer unit (60), the vibration which occurs in the vibration source (1) transforms into movement in the direction of orthogonal axis (I) seen in Figure 3.

The connecting rod (50), connected to the piston arm (62) provided in the transfer unit (60) by means of a hinge (63), transfers the movement, which is in the direction of the orthogonal axis (I) and coming from the transfer unit (60), to the crank arm (40). Said crank arm (40) is connected to the second end (52) of the connecting rod (50) by means of a connection pin (70). The crank arm (40) forms pendulum movement by making oscillation by means of the force received from the connecting rod (50). The pendulum movement coming from the crank arm (40) is transferred to the unidirectional clutch (30) by means of the crank shaft (80), thus, continuous rotational movement is obtained by means of the inertia disc (20) and the unidirectional clutch (30). The inertia disc (20) transfers the continuous rotational movement to the alternator (10) connected thereto. The mechanical energy, accumulated in the inertia disc (20) resulting from the continuous rotational movement, is transformed into electrical energy by the alternator (10).

In Figure 6, a representative perspective view of an alternative embodiment of the subject matter transforming system (100) is given. In the transforming system (100), two crank arms (40) can be connected to the connecting rod (50) in order to generate electrical energy during the movement of the pendulum movement, formed at the crank arm (40), in both directions. By using unidirectional clutch (30), inertia disc (20) and alternator (10) connected in different directions to each crank arm (40), electrical energy is obtained from movement of the pendulum movement in both directions. Thus, a transforming system (100) is provided with electromechanical structure which can generate electricity from the vibrations of loads with high force.

The protection scope of the present invention is set forth in the annexed claims and cannot be restricted to the illustrative disclosures given above, under the detailed description. It is because a person skilled in the relevant art can obviously produce similar embodiments under the light of the foregoing disclosures, without departing from the main principles of the present invention.
