Description
Technical Field

Background
With the development of modern industry, the demand for energy is increasing. For this reason, various safe, clean, and renewable new energy sources are continuously being explored and developed. Since the area occupancy of the ocean on earth is about 72%, the ocean stores a large amount of energy resources in the form of tides, waves, temperature differences of seawater, ocean currents and the like in addition to the aquatic and mineral resources which are well known to human beings. The wave energy has the advantages of large energy density, wide distribution area and the like, and if the wave energy is developed properly, the pressure of the current energy crisis can be effectively relieved. The total amount of ocean energy that can be theoretically regenerated worldwide is 766 hundred million kilowatts, and the technology allows the use of 64 hundred million kilowatts of power, which is about 2 times the capacity of the current worldwide generators. Among them, the wave energy density is the highest, about 20 hundred million kilowatts, and the development potential is very large. The energy of the ocean includes kinetic energy of seawater, including ocean current energy, wave energy and the like, the wave energy power generation refers to power generation by utilizing energy generated by vertical motion and horizontal motion of sea surface waves and pressure change of water in sea waves, and the wave energy is generally converted into reciprocating mechanical energy through a wave energy power generation device and then converted into electric energy. The basic research is a leading-edge field of multidisciplinary crossing, and is the comprehensive application of the multidisciplinary crossing such as machinery, electricity, fluid power and the like. Starting with the first patents relating to wave energy power generation published as early as the end of the eighteenth century, there are probably over three hundred different proposals in the world to date, the inventions being over a thousand. However, so far, in the actual marine service environment, most of wave energy power generation devices still lack the capability of long-term reliable operation, some key components of the power generation device system are corroded by seawater contact, the energy obtaining capability and the wave impact resistance capability of movable components of a transmission mechanism are poor, and the wave energy power generation device cannot bear collision and abrasion of wave load for a long time. These fundamental and fatal defects lead to equipment damage and even total sinking, which makes commercial use difficult. The current wave energy utilization technologies mainly comprise the following three types: oscillating water column technology, oscillating floater technology and wave crossing technology. The oscillating floater technology is to utilize waves to push the oscillating floater to move up and down to absorb wave energy, but the power generation device can only absorb the wave energy in a single direction when the oscillating floater rises or falls, namely in each wave period, general wave energy is not converted and absorbed to be effectively used.
Wave power generation is one of new energy power generation, and a wave power generation device is often used. For example, Chinese patent discloses a chain type wave energy power generation device (patent publication No. CN204877773U), which solves the technical problems that the common use period of the power generation device is short, and offshore and coastal wave energy power generation devices cannot be used for offshore wave energy power generation, which causes resource waste, by arranging a plunger type hydraulic pump, a power generation water turbine, an air bag, a shell and the like, but the patent has the problems that the air bag on the upper surface of the shell is easily corroded by seawater to damage air leakage after being used for a long time, so that the floating of the shell on the sea surface is influenced, the air bag is troublesome to replace, the work of workers is inconvenient, and the work intensity of the workers is increased.
