Embodiment Construction
[0023] figure 1 A structure and working state diagram of a vertical-axis tidal current energy generating device is shown. In the figure, the vertical axis tidal current energy power generation device uses the connecting rod 1 to connect the blade 3 to the main shaft 2, the tidal current acting on the blade 3 can make the main shaft 2 rotate, and the main shaft 2 is driven to generate electricity through the speed-increasing gearbox 4 and the universal joint 5 Machine 6 generates electricity. Two connecting rods 1 and one blade 3 form an impeller group, and the four impeller groups uniformly distributed in the circumferential direction are welded to the main shaft 2 by the large end of the connecting rod 1, and the slider 1d at the small end of the connecting rod 1 is embedded in the blade 3 Chute 3d. Speed-increasing gearbox 4 is fixed on the top plate 7a of protective cover 7 by bearing 9, and generator 6 is fixed on the inboard of protective cover 7 top plate 7a, and prote...

The invention discloses a vertical shaft tidal power generation device, and belongs to the technical field of tidal power generation. In the vertical shaft tidal power generation device, blades are connected to a main shaft by connecting rods; a tidal current which acts on the blades can rotate the main shaft; and the main shaft drives a generator for generating power through a speed-increasing gearbox and a universal joint. The connecting rods, the blades and the main shaft of the power generation device respectively adopt a telescopic structure locked by a locking mechanism, two connecting rods and one blade form an impeller assembly, circumferentially and uniformly distributed impeller assemblies are fixedly connected with the main shaft through the larger ends of the connecting rods, and sliders at the smaller ends of the connecting rods are embedded in chutes of the blades. The speed-increasing gearbox is fixed on a top plate of a protective cover through a support, and the generator is fixed on the inner side of the top plate of the protective cover. The protective cover also adopts a telescopic structure, and is fixed on a cement foundation through a base. The power generation device can reduce the volume of the whole device, facilitate the transport, avoid disassembly and assembly of various components, and reduce the seabed installation cost by over 50 percent than the original cost through effective expansion.
Description
technical field [0001] The invention relates to a vertical-axis tidal current energy generating device, which belongs to the technical field of utilizing tidal current energy to generate electricity. Background technique [0002] As a clean and renewable energy source, ocean energy is not only rich in resources, but also has little impact on the environment. At present, the theoretical total amount of renewable ocean energy resources in the world is 766,000GW, and the development prospects are very promising. my country has a long coastline and a vast sea area, and has abundant ocean energy reserves. The exploitable ocean energy resources include: tidal current energy, tidal energy and wave energy, etc. Among them, the theoretical average power of tidal current energy is 13940MW. Due to its strong predictability, tidal current energy has greater advantages than wave energy in stably providing electricity. At the same time, compared with the use of tidal energy, tidal curren...
