Description

The invention relates to the class of power plants that use the kinetic energy of a moving medium - air, water. A conveyor power station (RU Patent No. 2769598) is known, consisting of electric generators, pulleys connected to them, and a conveyor belt with aerodynamic plates enclosing the pulleys. This technical solution can be considered a prototype. One of the drawbacks of a conveyor power plant is its limited power output. Therefore, the objective of the present invention is to increase the power output of a conveyor power plant. The technical result will be a conveyor power plant with increased electrical output compared to the prior art. The stated problem is solved, and the technical result is achieved by the fact that the conveyor power station (CPS) consists of pulleys, electric generators mechanically connected to them, a closed belt with aerodynamic plates covering the pulleys, and linear electric generators of a transverse circuit, the ribs of the belt have a wavy shape, the magnetic-conducting circuits of the linear electric generators have several breaks, and the movable cores installed in the breaks are spring-loaded. The diagram of the proposed power plant (top view) is shown in the attached figure. It consists of electric generators (1), mechanically connected to pulleys (2). The pulleys are arranged with their axes of rotation horizontally and surrounded by a belt (3) with aerodynamic plates (4) located on it. The plates are shaped like a portion of the lateral surface of an elongated cylinder and are located on the belt with their longitudinal axes perpendicular to the plane of the belt and their chords at an angle to its centerline, with a uniform pitch between them. Linear transverse generators (5) are located at the rear of the station (RU Patent No. 2771661), and the belt edge facing them has a wavy shape. Linear transverse generators (at least one, as shown in the figure) may have several breaks in the magnetic conductive circuit and may be located on the front side of the power plant, provided that they do not significantly shade the aerodynamic plates from the wind. Movable magnetically conductive cores (6) are positioned within the gaps of the breaks, with free linear movement on steel balls across the magnetic flux of the circuit, compressed by springs (7). Linear electric generators of the transverse design are spaced from the belt at a distance such that the gaps between the movable cores, in their spring-extended position, and the straight edge of the belt are less than the height of the belt wave—in other words, in the zone of cam contact with the belt waves. The operation of the proposed CES is as follows. When a flow of fluid blows over the 4 plates at an angle of attack ϕ, a force F a develops between the chords of the 4 plates and the flow velocity vector V on each plate. This force is directed toward the curved surface of the plate and is maximum at the optimal angle of attack for the given plate shape. (This is completely analogous to the generation of the driving force on a sail.) For the plate arrangement shown in the figure, the driving forces of the upper row are directed to the right, and those of the lower row are directed to the left. The belt-3, which envelops the pulleys -2, under the action of the forces of the upper and lower rows of plates-4, begins to move linearly along itself (in the case shown in the figure, to the right), rotating the pulleys and the electric generators-1 connected to them, which generate electric current. At the same time, one of the waves of the moving belt's edge approaches one of the magnetic cores 6, which has been extended to its extreme position, presses on it, and moves it in the gap of the magnetic circuit to the opposite position, compressing the spring 7 that forces it out (the operation of a conventional cam pair). As a result of the movement of the moving core 6, the magnetic conductivity and magnetic flux in the gap change. These changes synchronously induce electromotive forces in the coils 8 of the linear transverse-circuit generator. If the coils are closed to the load, the currents generated in them by the electromotive forces flow to it. As the belt 3 continues to move, the wave that moved the magnetic core leaves from under it, and it returns to its original position under the action of the spring pressing it. The magnetic flux in the magnetic circuit of the linear transverse-circuit generator changes again, and an emf is generated again. Because there are many waves on the belt, the belt moves at high speed, and there are several discontinuities in the magnetic circuit, the magnetic circuit switching frequency is quite high, generating a correspondingly high emf. With an optimal ratio of the belt wave period Tb to the magnetic circuit discontinuity period Tm , Tb < Tmedemf will be maximal for a given number of waves and discontinuities. Although some of the moving belt energy (due to the transverse configuration of
