Shore type oscillating water column wave energy power generating device

Abstract

The invention discloses a shore type oscillating water column wave energy power generating device, and belongs to the technical field of wave power generation. The shore type oscillating water columnwave energy power generating device comprises a front wall, a back wall, a first gas chamber, wave power generating devices and a clearing device, wherein the front wall is positioned at one side of the rear wall; the first gas chamber is positioned between the front wall and the back wall; a plurality of wave power generating devices are positioned inside the front wall; a movable plate is arranged at the right side of the wave power generating device; and the clearing device is positioned at the left side of the front wall. The shore type oscillating water column wave energy power generatingdevice has the advantages that scientificity and reasonableness are realized; the use is safe and convenient; the energy in waves is converted into electric energy through the wave power generating device; the seawater energy utilization efficiency is improved; the impact force of the waves on the front wall is reduced; the service life of the front wall is prolonged; the movable plate increasesthe wave energy utilization rate when the sea level is lower than an opening at the lower side of the front wall; the movable plate automatically ascends or descends, and the use of other energy is not needed, so that the environment is protected, and the energy is saved; and the clearing device is used for effectively clearing sundries on a filtering screen, so that the energy conversion efficiency of the wave power generating devices can be favorably improved, and the waste in the sea can be favorably cleared.

Description

technical field [0001] The invention relates to the technical field of wave power generation, in particular to a shore-type oscillating water column wave energy power generation device. Background technique [0002] With the continuous development of the world economy, people's demand for energy continues to grow, and the national economic and social development of various countries cannot be separated from energy. However, as the human demand for energy becomes larger and larger, the problem of environmental pollution becomes more and more serious, and the development and utilization of clean energy is imminent. As the main body covering 70% of the earth's area, the ocean not only has rich oil and gas resources, but also contains huge energy. Recently, people have developed and utilized ocean wave energy; wave energy has a high capacity density, a wide distribution area, stable energy supply, and is often used to generate electricity. [0003] The existing shore-type osci...

Problems solved by technology

[0003] The existing shore-type oscillating water column wave energy generation device has low conversion efficiency for wave energy

When the sea level is lower than the opening of the front wall of the power generation device, the conversion efficiency of wave energy into mechanical energy is low; waves beating the front wall will cause damage to the front wall in the long run, and the energy of wave beating cannot be effectively used
