Abstract

The invention discloses a metro tunnel wind power generation device. The device comprises an electric generator, an energy storage system, a transmission shaft and impellers. The electric generator and the energy storage system are arranged inside a tunnel side wall top groove. Three tunnel side wall surface grooves which are distributed at equal intervals are formed under the tunnel side wall topgroove in the vertical direction. The transmission shaft is vertically mounted on the surface of the side all of a tunnel through a bearing pedestal. The top end of the transmission shaft is connected with a motor shaft of the electric generator through a bevel gear set. The electric generator is connected with the energy storage system, and the energy storage system is used for storing electricenergy generated by the electric generator. The three impellers are mounted on the transmission shaft and located in the three tunnel side wall surface grooves correspondingly. The impellers are connected with the transmission shaft through overrunning couplers, so that the three impellers are made to operate in a coaxial but non-linkage state relative to the transmission shaft and rotate independently on the transmission shaft. Three semi-circular-arc-shaped blades are arranged on each impeller, and the tunnel side wall surface grooves are each in a semi-circular-arc shape. During rotating ofeach impeller, only one blade is located outside the corresponding tunnel side wall surface groove and participates in doing work each time.

Description

technical field [0001] The invention belongs to the technical field of special wind power generation, in particular to a subway tunnel wind power generation device. Background technique [0002] In the subway tunnel, since the moving direction of the subway train is fixed, and the shape of the subway tunnel is also fixed, when the subway train runs at high speed in the tunnel, it will generate a strong directional airflow, and this directional airflow is relatively stable, so it can be For wind power generation. [0003] At present, although many tunnel wind power generation devices have appeared, the actual power generation effect is not ideal. For example, the Chinese patent application number 201220093939.3 discloses a vertical axis wind power generation system using wind energy in subway tunnels. The impeller structure includes Four integral blades with a certain height are used. Since the airflow in the tunnel is not evenly distributed in the vertical space, it cannot ...
