Wave Power Equipment

Abstract

Invention relates to devises for conversion of the energy of waves into electric energy and solves a problem of reliability improvement and operating efficiency of the wave power plant, reduction of hydraulic losses when water is pumping over pipeline as well as reduction of expenses for manufacturing, installation and operation. Solution of the problem stated is obtained hereby that the known wave power plant comprises at least one floating-type water pump, hydraulic turbine with electric generator, pipeline connecting water pump with hydraulic turbine additionally comprises offshore unit with platform placed above sea surface when hydraulic turbine with electric generator are installed at the platform. The suggested plant can additionally comprise damper or accumulative tank placed at the platform. The suggested plant can be equipped with crane as well. In this case the floating-type water pump in suggested wave power plant can be installed directly at the platform at its low part and provide with water supply both while float goes only down and when float moves in both directions - up and down. Moreover the floating-type water pump installed below can be fixed at removable part of the platform and be lifted above the platform by means of crane during installation works or maintenance. Implementation of the given invention can be put into effect at both specially constructed for this plant new offshore units and at the already existed offshore units.

Description

technical field [0001] The invention relates to the field of renewable energy, in particular to a device capable of converting hydraulic energy into electric energy. Background technique [0002] The currently used wave power generation equipment includes at least one suspended water pump, a generating turbine and a pipeline connecting the water pump and the turbine (refer to patent RFNO: 2316670). In addition, the device also includes a vertical bearing installed in the lower part of the open water, with a swinging rod, and on its upper part, a floating device is installed. The floating device is installed at the end of one end of the rod, and the other end of the rod is physically connected to the water pump. The water turbine carrying the generator is located on the shore, and the pipeline that supplies water between the water pump and the turbine through an intermediary tank is also located on the mountain, and the waste water is transported back to the open water throug...

AI Technical Summary

Problems solved by technology

[0004] The deficiencies of the designs described above result in a significant loss of energy in use with today's equipment, which is due to the fluid resistance that occurs when water enters the tank through the pipes from the open water surface

During use, the surface inside the pipeline will be quickly polluted by pumping in seawater, making the inner diameter of the pipeline smaller and usually causing the equipment to lose some efficiency, because the water capacity becomes smaller and the cost of additional replacement pipelines is increased, thereby increasing The cost of using the above equipment

[0005] Another disadvantage is the instability of the floating pump support system

When the waves are high, there is a direct upward force that affects the flotation device, which can cause a dragging movement of the anchor, which can capsize the entire system

[0006] Another disadvantage is the known inefficiency of the floating system, which reduces the efficiency of the use of waves

Many floating systems connected to it have to be installed over a large area to increase production efficiency, which in turn increases manufacturing, installation and operating costs
