Description

technical field [0001] The invention relates to a device for converting low-speed and disordered low-grade mechanical energy of sea waves into high-grade energy, in particular to a reciprocating sea wave power generation device. Background technique: [0002] The ocean area accounts for more than 70% of the earth's surface. Ocean wave energy is the most abundant, most common, inexhaustible, inexhaustible, and most reliable resource that is better utilized in ocean energy. Wave energy is an ocean energy that accounts for a large proportion of ocean energy. The wave motion of sea water produces a very large amount of energy. It is estimated that the readily available wave energy in the world's oceans is more than 70 billion kilowatts, accounting for more than 94% of the easily available energy in all oceans. [0003] Wave energy is the cleanest renewable resource. Its development and utilization will fundamentally alleviate the crisis caused by the gradual depletion of fossi...

Problems solved by technology

[0009] Other types of mechanical energy conversion devices are difficult to use because they are difficult to achieve continuous, stable, concentrated, and uniform speed controllability.

[0010] Although these three types have their own advantages, their common disadvantages are: 1. There are many intermediate links for converting sea wave energy into electric energy, complex equipment, low efficiency, and difficult to form a scale; 2. Only part of the mechanical energy of sea waves can be used. Absorbing disordered, scattered, low-density, and unstable wave energy leads to high power generation costs; 3. Wave energy conversion devices and their structures have poor ability to withstand disastrous marine climates, and are not easy to resist damage from typhoons and tsunamis , greater safety hazard

[0011] Recently, the United Kingdom and other Western European countries have developed buoy-type sea snake technology. They use several buoys connected in series to ride on the waves, and use the changes in the undulating slope angle of the waves to push the pistons of the buoys to generate electricity. This method can indeed make the system The wind and wave resistance can be enhanced, but because the undulation of the wave itself is very gentle, the angle change is also small, and it is perpendicular to the wave crest line, so a string of buoys can only correspond to waves with a small width, and the efficiency is not ideal. Its ability to resist typhoons and tsunamis is not enough, and it has not overcome the above problems

[0012] Due to various technical problems, the cost of wave power generation is about 10 times higher than that of thermal power and there are safety hazards
