Description

technical field [0001] The invention belongs to the technical field of fluid machinery and water conservancy and hydropower engineering equipment, and in particular relates to an energy collection device for generating electricity by using ocean energy. Background technique [0002] Traditional energy sources are about to be exhausted and have brought about serious environmental problems, and it is urgent to find and develop alternative new energy sources. The world's oceans are rich in resources, and the waves contain huge energy. The use of ocean waves to generate electricity does not require fuel and has little impact on the environment, so it has great development and utilization value. [0003] Chinese patent application 201320156401.7 "Hydraulic water surface power generation device" discloses a device that utilizes the vertical displacement of waves to convert vertical wave energy into mechanical energy and drives a turbine to generate electricity, which improves the...

Problems solved by technology

It solves the problems of low wave energy conversion efficiency of current wave energy collection and conversion devices, short service life of equipment, and high production costs.

However, since the slope of the wave-guiding plate of the device is fixed, it cannot be automatically adjusted according to the local real-time wave height and wavelength, and the energy obtained from the wave is still limited.

[0006] To sum up, the existing wave power generation devices generally have defects such as low wave energy conversion rate, small output power, poor stability, and short effective working time of the device. One of the key problems to be solved urgently in the technical field
