The invention discloses a special fan blade applied to a power generation device in an area with abundant tidal energy, which belongs to the field of fan blades of tidal energy generators, and a special fan blade used in a power generation device in an area with abundant tidal energy. The problem of damage to the tidal power generation device is that when the tidal energy is in a moderate state, the impact of the tidal flow on the current limiting end will push the current limiting end and the additional panel out of the movable chute, increasing the overall impact of the fan blade body increase the tidal energy utilization efficiency of the fan blade body, and when the tidal energy is too strong, the additional panel will be further pushed out from the movable chute, and the pressure relief hole will leak out, and the excessive tidal flow will pass through the induced The circulation groove, movable chute and pressure relief hole directly penetrate the fan blade body, reducing the loss of the fan blade body due to excessive tidal flow, greatly reducing the construction cost of the tidal power station and reducing the maintenance cost of the tidal power generation device. Maintain the normal operation of tidal power plants.
Description
technical field [0001] The invention relates to the field of fan blades of tidal energy generators, and more specifically relates to a special fan blade applied to power generation devices in areas with abundant tidal energy. Background technique [0002] Tidal energy is the energy contained in the periodic fluctuations of seawater. Its water level difference is expressed as potential energy, and the speed of its tidal current is expressed as kinetic energy. These two kinds of energy can be used, and it is a kind of renewable energy. The flow of tidal water is different from the flow of river water. It is constantly changing direction. There are three forms of tidal power generation: generator main body (1) single-storage one-way power station That is to say, only one reservoir is used to generate electricity only at high tide (or low tide). The fan blade body (2) single reservoir two-way power station uses one reservoir, but it can generate electricity at high tide and low...
