Multi-dimensional parallel swing wave power generation device

Abstract

The invention provides a novel multi-dimensional parallel connecting swing wave power generation device which comprises a mixed oil tank, a lower platform, rotary platforms, six sets of parallel hydraulic cylinders, an upper platform, a swing rod, a three-freedom-degree kinematic pair, a top cover, a rib plate and a floating box. The top cover is fixedly connected to the inner wall of the upper end of the floating box. The outer ring of the three-freedom-degree kinematic pair is fixed with the top cover, and the inner ring of the three-freedom-degree kinematic pair and the swing rod form a moving pair. One end of the swing rod penetrates through the top wall of the floating box and is fixedly connected to an external device, and the other end of the swing rod is fixedly arranged on the upper platform. Piston rods of the six sets of parallel hydraulic cylinders and the upper platform are in universal joint connection, and cylinder bodies of the six sets of parallel hydraulic cylinders and the rotary platforms form two spherical pairs. The rotary platforms and the lower platform form spherical pairs. The lower platform is fixedly arranged on the mixed oil tank, and the mixed oil tank is fixedly connected with the bottom of the floating box. The novel multi-dimensional parallel connecting swing wave power generation device has the advantages of being high in power generation capacity, high in sea wave energy utilization rate, long in service life, small in pollution and the like, and is capable of absorbing sea wave swing energy in the horizontal direction, and capable of absorbing sea wave energy in the vertical direction.

Description

technical field [0001] The invention relates to the technical field of wave power generation, in particular to a multi-dimensional parallel swing wave power generation device. Background technique [0002] The undulating sea is a kind of marine resource. On the sea surface of 1 square kilometer, there is 200,000 kilowatts of wave motion energy per second. There are various forms of wave power generation, some use the up and down fluctuations of waves, some use the lateral movement of waves, and some use the pressure changes in water generated by waves, etc. [0003] In 1964, Japan was the first to manufacture a beacon light that uses ocean waves to generate electricity. Subsequently, many countries in the world, such as the United Kingdom, the United States, Canada, Finland, Denmark, France, etc., are researching and testing wave power generation, and have successively proposed hundreds of power generation device designs. However, due to various technical problems, the re...

AI Technical Summary

Problems solved by technology

Through the combined effect of the floating body and the balance floating body, the device transfers the energy of the floating body when it descends in the vertical direction to the flywheel of the output shaft through the pulley, and then ensures the normal power generation of the permanent magnet synchronous generator on the output shaft through the inertia of the flywheel. The device has the following disadvantages: the device only utilizes the energy when the floating body descends, and does not utilize the energy of the floating body rising and the lateral swing of the waves, resulting in a low utilization rate of wave energy
