RU174403U1 - WAVE POWER INSTALLATION - Google Patents

Abstract

The utility model relates to hydropower installations and can be used to generate environmentally friendly inexhaustible energy in various industries. Energy is achieved by the fact that in a wave power plant containing a vertical cylindrical pipe with a float, a check valve and an anchor system, the pipe is conical, tapering in the upper part, in which guide vanes and a hydraulic turbine rotate the electric generator, and the check valve is made in the form of shutters single-acting, a spherical reflector is installed above the turbine in the upper part. Spatial fixation of the installation is carried out by the anchor system. To increase the energy received, several units can be combined into a single circuit. A single module can be used to provide power to remote beacons offline.

Description

The utility model relates to hydropower plants and can be used to generate environmentally friendly inexhaustible electricity.

Known devices for generating electricity based on the conversion of mechanical energy into electrical energy. For example, a wave power device (patent No. 2377424. Published November 20, 2009) represents a system of shafts, gears, couplings associated with floating pontoons. The disadvantages of this device are that in all mechanical devices there are large power losses and large floating objects, in the form of pontoons, are required to overcome them to obtain significant Archimedean force. Such pontoons do not respond to small waves, so such devices are ineffective.

Pop-up buoy converters of mechanical energy are known, for example, a wave pump (in the book by A. da Roza. Renewable energy sources. Physicotechnical fundamentals. Textbook. Publishing House Intellect, Publishing House MPEI, 2010, 704 s, fig. . 14.2, p. 682.). This device is a long vertical pipe with a buoy at the upper end and a check valve at the lower end of the pipe. When moving the pipe with the water filled in it down into the trough of the wave, the water in the pipe splashes up and rotates the turbine. This device is taken by us as a prototype. The disadvantages of the prototype are as follows: to obtain sufficient energy of the water column in the pipe, it is necessary to perform a long length, which forces it to be used only at great depths (at least 50 m.); significant dimensions of the device determine its large mass, which leads to low sensitivity to small waves and inefficiency at medium and small waves.

The technical result, the achievement of which is directed by a utility model - expanding the range of use and increasing the efficiency of the installation. This result is achieved by the fact that in a wave power plant containing a vertical cylindrical pipe with a float, a check valve and an anchor system, the pipe is made conical, tapering in the upper part, in which guide vanes and a hydraulic turbine rotate the electric generator, and the check valve is made in the form of single-acting blinds, above the hydraulic turbine, a spherical reflector is installed in the upper part. Around the electric generator there is an aerodynamic screen.

The proposed device is presented in FIG. 1. Wave power plant - general view; FIG. 2.- check valve; FIG. 3. - working blades (deployed).

The proposed device is a vertically arranged conical pipe with a wide part at the bottom 1. The vertical position of the housing 1 provides a float 4 mounted in a narrow part of the housing, and supporting positive buoyancy of the device. In the upper narrow part of the housing 1, inside, there is a guide apparatus 2, consisting of a series of radially located inclined blades. Above the guide apparatus 2 there is a hydraulic turbine 3 with radially located active blades that are mounted on the shaft 5. The shaft 5 in the upper part is connected to the rotor of the electric generator 7. Around the electric generator 7 there is an aerodynamic screen 6, and between the hydraulic turbine 3 and the electric generator 7 there is a spherical reflector 8 in in the form of a plate with a convex part directed upwards. In the lower part of the housing 1 installed shutter check valve 9, which are based on the lattice 10.

The proposed device operates as follows:

When the installation is on the crest of the wave, water completely fills the entire volume of the housing 1. When lowering the housing 1 downward from the wave crest, water cannot flow out of the housing 1, because this is prevented by the shutter of the non-return valve 9 and water rushes into the upper part of the housing, and, due to confusion, there is an increase in the rate of flow of water. This water enters the guide vanes of the apparatus 2 and acts on the active vanes of the hydro turbine 3. The hydro turbine 3 starts to rotate, the shaft 5 rotates and the rotor of the electric generator 7 spins. An electric current is generated, which is sent to the consumer through the wires. After the passage of the turbine 3, the flow of water hits the reflector 8 and flows outside the housing 1. The presence of the reflector 8 protects the generator 7 from water. When the housing 1 moves down from the wave crest, simultaneously with the outflow of water through the top, the housing 1 is filled with a new portion of water through the open shutter of the non-return valve 9. Further, when lifting the device to the wave crest, the whole cycle is repeated. As a result of the operation of the device, the electricity generated by the electric generator is transmitted through a common cable to the shore for use by consumers.
