Combined wave energy and tidal current energy power generation device

Abstract

The invention provides a combined wave energy and tidal current energy power generation device. A wave vibration assembly comprises a floating block, the lower part of the floating block is connectedwith a connecting pipe through a cardan shaft, the lower end of the connecting pipe is perpendicularly rigidly connected with a support plate, and racks extend downwards from the diagonal positions ofthe support plate respectively; a generator assembly comprises a stator, two rotors are arranged at both ends in the stator, the two rotors are coaxially connected with rotor shafts respectively, andsecond one-way gears on the rotor shafts are meshed with the racks; a tidal current energy assembly comprises a forward impeller and a reverse impeller located at both ends of the generator assemblyin the axial direction, and a drive shaft parallel to the axial direction of the generator assembly; a pair of meshing gears are arranged on the drive shaft; each meshing gear is fixedly connected with the forward impeller and the reverse impeller in the axial direction, and transmission gears are meshed with the corresponding meshing gears. According to the device, the problems that a tidal energy generator and a wave energy generator need to be installed at the same time, the installation is troublesome, and a large area is occupied are avoided, and the power generation device has significant improvement in the design of balance and stability.

Problems solved by technology

[0002] Tidal energy generators and wave energy generators are important components of seawater tidal current power generation. In order to improve the power generation efficiency of seawater tidal current power generation, tidal energy generators and wave energy generators are often installed separately in the sea, but tidal energy generators are installed separately. Generators and wave energy generators are very troublesome in the installation process, and the installation of the two generators occupies a relatively large area, thereby reducing the number of installed generators

[0003] In the prior art, there are also cases of integrated design of tidal current power generation and wave power generation, but there are deficiencies in the design of the balance and stability of the power generation device, especially for the combined wave power tidal current fixedly installed on the seabed. As far as power generation devices are concerned, due to the large force of the water flow, the design of the prior art cannot meet the requirements of balance and stability
