A tidal power generation device with catenary blades

Abstract

The invention discloses a tidal power generation apparatus with catenary suspension type blades. The tidal power generation apparatus include a water flow channel formed by connecting a horizontal wall a, a horizontal wall b, a vertical wall c, and a vertical wall d; a vertical impeller main shaft is arranged in the water flow channel; the impeller main shaft is sleeved with an impeller; and one end of the impeller main shaft is connected to the wall a, the other end of the impeller main shaft passes through the wall b and is connected to an engine main shaft through a coupling member. According to the invention, a power generator main shaft is arranged outside of the water flow channel, a seal and damp-proof problem of the power generator can be avoided; the Z-shaped water flow channel is flat and smooth, and loss is less in a flowing process; the water flow channel does not have to be designed into a diffusion channel, the earth and stone excavation amount of a power generation station is reduced, and operation and maintenance is facilitated; the catenary suspension type blades are adopted, the machining and design cost is low; the rotation directions are consistent in a forward working condition and a backward working condition; the problem that the conventional tidal power generation stations are huge in investment cost and are complex in unit structure can be overcome; and the tidal power generation apparatus has high use value.

Description

technical field

[0001] The invention belongs to the technical field of tidal power generation equipment, in particular to a tidal power generation device with catenary blades. Background technique

[0002] With the continuous advancement of my country's supply-side reform, tidal energy, a clean and efficient energy source, has received more and more attention. According to past experience, the most economical and effective power generation method in tidal power generation is the one-reservoir two-way power generation method, that is, a single reservoir can generate power at high tide and low tide, and maximize the use of water energy resources. In order for the tidal power station to have the ability to generate electricity in both directions, its runners and channels must be specially designed. For tidal power stations with large investment, bulb tubular turbines are generally selected as their main models, and the runner blades are specially designed on the basis of tradi...
