Description

Sea wave power generation device

Technical Field

The utility model belongs to the technical field of the electricity generation, a sea water power generation facility is related to, especially, relate to a sea wave power generation facility.

Background

Nowadays, wave power generation devices using sea waves to generate electricity are increasingly becoming new research hotspots, and are also important solutions to the problem of energy shortage faced at present. The wave energy absorption and electric energy conversion efficiency of the wave power generation device is an important index for judging the performance of the wave power generation device. At present, the existing wave energy power generation device can be mainly divided into a plurality of main structural forms such as a vibration water column type, a cofferdam type, a vibration floater type and the like.

Existing wave power plants can also be divided into three main categories, according to the principle of the transmission of the wave energy conversion device and the type of transmission medium: air or water flow type wave power generation devices, hydraulic transmission type wave power generation devices and wave power generation devices of direct-drive linear permanent magnet motors. Wave power generation devices using air or water flow as a transmission medium usually need to use the rotational kinetic energy of a vortex machine to drive a generator to work to generate electricity, but the wave power generation devices are greatly dependent on the structural form of air or water flow channels and the dynamic pressure difference of water flow or air. This therefore inevitably increases the cost of the device and reduces the overall conversion efficiency of the wave energy.

When a hydraulic transmission type wave energy power generation device is adopted, kinetic energy of wave vibration needs to be converted into high-pressure hydraulic flow through a high-pressure hydraulic pump firstly, and then is further converted into electric energy output through an induction generator driven by a hydraulic motor. The wave energy power generation device in the hydraulic transmission form is mainly used in a front-back oscillation structure form in a raft form, and can also be in a structure form of parallel combination of a plurality of hydraulic motors and hydraulic pumps. Although the wave energy power generation device in the hydraulic transmission mode has the advantages of relatively compact structure, high reliability and the like, the hydraulic transmission type wave energy power generation device is low in overall conversion efficiency and has the characteristics of environmental friendliness and the like.

The wave power generation device of the direct-drive linear permanent magnet motor can adopt a permanent magnet linear motor driven by a floating rope or a direct-drive permanent magnet generator rigidly connected with a floater. The direct-drive structure is used for directly converting wave kinetic energy into the electricity generation electric energy of the permanent magnet generator without an intermediate transmission and connection mechanism.

The wave power plant of the direct drive permanent magnet motor therefore has fewer movable and rotating parts and therefore less complexity and associated maintenance requirements. However, the overall structure of the wave power generation device of the direct-drive permanent magnet generator is generally heavy and bulky, and the efficiency of wave-power conversion under low-speed reciprocating wave motion is low. Therefore, in general, the wave power generation device adopting the direct drive type of the linear motor often has the problems of low power conversion efficiency, deviation of output power quality and the like.

In summary, the existing wave energy power generation devices usually adopt three types of transmission modes, and all the three modes have various disadvantages, such as a series of problems of complex structure, low structural reliability, low wave-to-electricity conversion efficiency and the like, and are difficult to be applied to wave energy power generation in open sea on a large scale.
