The energy superposition wave power generation device comprises a supporting mechanism, a wave energy collecting assembly, a multi-floater hydraulic energy storage system and a power generation system. The supporting mechanism is provided with a plurality of guide bars arranged in parallel. The wave energy collecting assembly comprises the multiple floaters arranged in parallel. The floaters are installed on the guide bars in a penetrating mode. At least one end of each floater is provided with a vertically sliding mechanism. The vertically sliding mechanisms are connected with the input end of the hydraulic energy storage system through pinion and rack transmission mechanisms. The output end of the hydraulic energy storage system is connected with a power generator of the power generation system. The energy superposition wave power generation device can collect energy generated in the ascending motion stroke and the descending motion stroke of the floaters at the same time; the superposed output of the energy of the multiple floaters is achieved through the hydraulic energy storage system, and the efficiency of the power generator is improved; and besides, the height of the whole device can be adjusted according to different sea areas and the sea conditions of different seasons, the motion strokes of the floaters are made to be optimal, the adaptability is high, and the stability is good.

Description

technical field [0001] The invention relates to a marine wave energy generating device, in particular to a single-degree-of-freedom multi-float combined energy superposition wave energy generating device. Background technique [0002] The depletion of fossil energy and the environmental problems caused by the use of fossil energy have become increasingly prominent. The development and utilization of new green energy has become the focus of attention of countries all over the world. Various technologies such as wind power generation, solar power generation, and tidal power generation are developing rapidly. Wind power generation is highly dependent on the wind, occupies a large area overall, and affects the survival of birds and the ecological environment. Solar power generation is limited by photoelectric conversion devices. The production of silicon, the main material of the conversion device, seriously pollutes the environment, and the cost is high; tidal power generation ...

Problems solved by technology

At present, there are several types of common wave energy generation devices: one is a single-float oscillating water column type power generation device, but its power generation efficiency is low, the cost of power generation is high, and it is difficult to popularize and apply; the other is a floating power generation device, but its capture structure The volume is huge, the draft area of ​​the device is large, the effect of wind and waves is obvious, its own stability is poor, and the efficiency of wave energy absorption and utilization is low; one is to shrink the channel to introduce waves into the high-level reservoir, and use the water level difference to drive the hydro turbine generator set to generate electricity. Large, but strict requirements on terrain, huge cost, difficult to promote
