Description

The utility model relates to the field of electrical engineering and is designed to generate electrical energy from the mechanical energy of passing vehicles on a road surface equipped with artificial bumps.

There is a known system for autonomous power supply and recharging of mobile devices at vehicle stops (patent RU No. 2665479, IPC H01L 41/113, E01F 11/00, H02K 35/02, publ. 08.30.2018 Bulletin No. 25), containing combined artificial humps (IN ), containing fixed and removable sections, characterized in that the removable sections of the IP are made of double-leaf with an axis in the middle, under each of which electrical converters (EC) of reciprocating movements are installed with the rotor axes and receiving elements in contact with the axes of the double-leaf IN, and the force the return of the axes and sections of the double-leaf INs to their original position is ensured by magnetic repulsion forces acting between the rotor and the stator magnetic system in each ED; the electrical outputs of each ED are connected to the inputs of the electrical energy adder introduced into the system through individual rectifiers, the outputs of which are connected in parallel and connected to the terminals electric battery; in addition, a receiving unit is introduced into the system and placed in a vandal-proof container, inside of which there is an electrical energy adder with wire inputs from the electric outputs of the electric power supply, an electric battery and a panel with sockets for powering consumers, located on the front wall of the vandal-proof receiving unit.

The main disadvantage of this system is low reliability due to the presence of double-leaf removable sections, which in this case act on the rotors in both axial and radial (when a vehicle hits an obstacle) directions, which leads to rapid failure of both removable sections and and rotors.

The closest in technical essence is a mobile electromechanical energy generator (patent for PM RU No. 189058, F03G 7/08, H01M 10/60, published 05/07/2019 Bulletin No. 13), consisting of springs, a layered piezoelectric element, an uneven cover, and electrical wires and racks, characterized in that the design is supplemented with a base with fastening elements and a screw electrical connector, a current rectifier, an amplifier and a battery placed in a thermal case with a low-current heating element.

The main disadvantage of this generator is its low reliability due to the presence of springs, which, with prolonged periodic exposure, gradually lose their elasticity, transferring the main mechanical impact to the piezoelectric element, which leads to its rapid failure.

The technical result is the creation of an electromechanical energy generator that makes it possible to increase reliability by eliminating a large number of moving elements, duplication due to the presence of additional piezoelements and additional covers that ensure return to the original position only due to the elasticity of the cover material and its shape in the form of a hollow regular triangular pyramid.

The technical solution is an electromechanical energy generator, which includes a rectangular body with elements for fastening to the road surface, a main cover inserted into a recess corresponding to the overall size in the body, and a main piezoelectric element installed between them, connected by a cable to a source of energy consumption through a rectifier, battery and power stabilizer.

What is new is that the main cover is made of elastic material in the form of a hollow regular triangular pyramid with a height of 0.5–1.5 mm, from the inside under the top of which the main piezoelectric element is installed, one of the sides of the base of the pyramid is located at the level of the road surface along the long side of the base of the body , which is additionally equipped with additional covers with corresponding additional piezoelements, manufactured similarly to the main ones, and the additional covers are installed in the housing similarly to the main cover relative to the long sides of the housing base, at a distance from the edges of the housing, from each other and/or the main cover 10–50 mm one at a time from the long sides of the base of the body.

In fig. Figure 1 shows a general view of an artificial bump with an energy generator.

In fig. Figure 2 shows a top view of an artificial bump with a power generator.

In fig. 3 shows a section A-A of FIG enlarged and rotated by 90°. 2.

The electromechanical energy generator includes a rectangular base housing 1 (Fig. 1-3) with fastening elements (not shown) of any known design (the author does not claim this) to the road surface 2 (Fig. 3), a main cover 3 (Fig. 1 -3), inserted into a sample 4 corresponding to the overall size in the housing 1, and installed between them by the main piezoelectric element 5 (Fig. 3), connected by cable 6 to a source of energy consumption through a rectifier, battery and power stabilizer (not shown) of any known design (the author does not claim this). The main cover 3 is made of elastic material (spring steel, glass fiber reinforced dense polyurethane, carbon fiber sintered with epoxy resin and/or the like) in the form of a hollow regular triangular pyramid with a height of h = 0.5–1.5 mm (Fig. 3 ), from the inside under the top of which the main piezo element 5 is installed. One of the sides 6 (Fig. 1-3) of the base of the pyramid of the main cover 3 is located at the level of the road surface 2 along the long side of the base of the body 1, which is additionally equipped with additional covers 7 with corresponding additional piezo elements 8 (Fig. 3), manufactured similarly to the main ones. Additional covers 7 (Fig. 1-3) are installed in the housing similarly to the main cover 3 relative to both long sides of the base of the housing 1 (Figs. 1 and 2), from the edges of the housing 1, from each other and/or the main cover 3 at a distance l= 10–50 mm along one of the long sides of the base of the housing 1.

The body 1 may be made of reinforced concrete, stainless steel, reinforced vulcanized rubber or the like. (the author does not claim this). The manufacture of covers 3 and 7 in the form of a hollow regular triangular pyramid with a height h = 0.5–1.5 mm (Fig. 3), as shown by bench tests, ensures long-term operation (almost the entire service life of body 1) without the release of material from covers 3 and 7 beyond the limits of elastic deformation and, as a consequence, preventing destruction during operation when vehicles pass through the covers 3 and 7. The location of one of the sides 6 (Fig. 1-3) of the base of the pyramid of the cover 3 and 7 along the long side of the base of the body 1 ensures a collision with wheels transport onto the flat edge of the cover 3 and/or 7 without distorting the transport wheels, which eliminates unauthorized deviation of transport from the trajectory, increasing traffic safety. The location of one of the sides 6 (Fig. 1-3) of the base of the pyramid of the cover 3 and 7 at the level of the road surface 2 provides maximum mechanical impact on the covers 3 and/or 7 when colliding with the wheels of a vehicle, since in addition to the mass of the vehicle, kinetic energy also acts, depending on the speed and mass of the vehicle, when the linear direction of the vehicle changes in the forward and upward direction, which leads to a more intense effect of the covers 4 and 7 on the corresponding piezoelements 5 and 8 and, as a consequence, the generation of additional electricity transmitted through cables 6. Location of the covers 3 (Figs. 1 and 2) and 7 in housing 1 relative to both long sides of the base of housing 1 ensures the versatility of the design, since it works to generate energy in both one and the other direction when vehicles pass. The location of covers 3 and 7 in housing 1 also at a distance from the edges of housing 1, from each other and/or the main cover l=10–50 mm (selected empirically) along one of the long sides of the base of housing 1 ensures guaranteed operation of the electromechanical energy generator independently on the thickness of vehicle wheels (with the exception of bicycles and scooters with thin wheel rims, which is not so significant in the total energy production).

Structural elements, air ducts, seals, technological fastenings, etc., which do not affect the explanation of the operation of the electromechanical energy generator, are not shown in the drawings (Fig. 1, 2 and 3) or are shown conditionally.

An electromechanical energy generator works as follows.

In a place chosen in accordance with traffic rules and the decision of the authorities, agreed upon with the traffic police of the locality or region, to install an artificial hump, traffic is first blocked and the road surface 2 is grooved (not shown) (Fig. 3) with the required number of cables 6 laid inside road surface 2. Outside the laid cables 6, the housing 1 (Fig. 1-3) is installed in fixation on the road surface 2 (Fig. 3) with fastening elements. The main 5 and additional 8 piezoelectric sensors are connected to the corresponding cables 6 and installed in the housing 1 in their places. The piezo sensors 5 and 8 are closed from the outside with the corresponding main 3 (Fig. 1 and 2) and additional 7 covers inserted into the corresponding selections 4 of the housing 1. After which the other ends of the cables 6 (Fig. 3) with a source of energy consumption through a rectifier, battery and power stabilizer (the author makes no claims to the design and methods of operation of these devices) and opens traffic.

When passing through an electromechanical energy generator, the transport wheels act on one or more covers 3 and/or 7, which, slightly straightening, exert pressure on the corresponding piezoelectric sensors 5 and/or 8, which generate electrical energy. Electrical energy is directed through the corresponding cables 6 through a rectifier, a battery and a power stabilizer to sources of energy consumption for lighting, heating sections of the road, to charging stations for electric vehicles, or the like. After the vehicle passes, the covers 3 and/or 7, under the action of internal elastic forces, return to their original state until the next interaction with the wheels of the vehicle to generate electrical energy.

The proposed electromechanical energy generator allows increasing reliability by eliminating a large number of moving elements, duplication due to the presence of additional piezoelements and additional covers that ensure return to the original position only due to the elasticity of the cover material and its shape in the form of a hollow regular triangular pyramid.
