Mechanical rectification wave energy absorption power generation device

Abstract

The invention relates to a mechanical rectification type sea wave energy absorbing power generation device. The mechanical rectification type sea wave energy absorbing power generation device comprises an energy capturing mechanism for capturing ocean wave energy and converting the ocean wave energy into kinetic energy of the energy capturing mechanism and an energy converting mechanism used for absorbing the kinetic energy of the energy capturing mechanism and converting the kinetic energy into electric energy. The energy converting mechanism comprises a mechanical rectification unit and a power generation unit. The mechanical rectification unit can convert the kinetic energy into the continuous one-way rotation mechanical energy of an input rotation shaft. The power generation unit is used for converting mechanical energy into electric energy. On the basis of an electromagnetic vibration energy collection device and mechanical rectification on the energy conduction process, irregularup-down reciprocating vibration energy of sea waves can be absorbed and converted into one-way rotation of a power generator rotation shaft, very high energy conversion efficiency and reliability areachieved, stable and efficient power supply can be provided for small beacons or ocean-going ships or other offshore infrastructures, the work duration is prolonged or the cruising capability is improved.

Problems solved by technology

[0003] The 21st century is the century of the ocean. The vigorous development and utilization of marine resources has become an important force to promote economic and social development. The problem of continuous power consumption of offshore facilities, especially offshore infrastructure, has become an important factor restricting marine development and utilization activities. The more common one is solar power generation. Although solar power generation has the advantages of cleanliness and environmental protection, it is severely restricted by meteorological conditions. Specifically, it is greatly affected by the temperature difference between day and night and sunlight, and it does not have 24-hour power generation capacity.

At present, the power generation devices used by low-power offshore equipment such as lighthouses and fishing boats are mainly power collection systems such as pneumatic turbines, hydroelectric motors, and DC electromagnetic generators. Poor maneuverability, inconvenient operation, low flexibility in actual use, low energy conversion efficiency, and poor applicability. Due to the above-mentioned shortcomings, the offshore power generation devices in the prior art cannot be used for small lighthouses or ocean-going vessels. The facility provides long-lasting, stable and efficient power supply, which cannot effectively meet the requirements of working at sea to improve its working hours or battery life
