An open-air hydroelectric generator set that utilizes the ecological flow of a hydropower station to generate electricity

Abstract

The invention relates to an outdoor hydroelectric generating set generating electricity through hydropower station ecological flow. The outdoor hydroelectric generating set generating electricity through the hydropower station ecological flow is characterized by comprising a water turbine, a horizontal type asynchronous generator, a water inlet valve, a diffusion pipe and a hammer type butterfly valve; the diffusion pipe is arranged at the tail end of a branched pipeline which is perpendicularly connected with a main pipeline of an ecological flow drainage pipe; the convergence end of the diffusion pipe is connected with the tail end of the branched pipeline; the diffusion end of the diffusion pipe is connected with a water inlet of the water turbine; the water turbine is connected with an asynchronous motor to drive the asynchronous motor to generate electricity; the water inlet valve is arranged on the branched pipeline which is connected with the diffusion pipe; the hammer type butterfly valve is arranged at a water outlet of the ecological flow drainage pipe; the water inlet valve is opened and the hammer type butterfly valve is closed when the water turbine drives the asynchronous generator to generate electricity, the ecological flow sequentially passes the main pipeline, the water inlet valve and the diffusion pipe to flow into the water turbine, the water turbine drives the asynchronous generator to generate electricity, and the ecological flow after work is discharged through the water turbine; when the asynchronous motor does not generate electricity, the hammer type butterfly valve is opened and the ecological flow is discharged through the hammer type butterfly valve.

Description

technical field

[0001] The invention relates to a hydroelectric power generation device, in particular to an open-air hydroelectric generating set that utilizes the ecological flow of a hydropower station to generate electricity. Background technique

[0002] Diversion hydropower stations account for a high proportion of small and medium hydropower stations. Such as figure 1 As shown, the common power generation mode of diversion-type hydropower stations is to build a barrage in the river, and then use channels or diversion pipes to divert the water flow from the high water level to the location with a relatively large drop in the lower reaches of the river to build a power station for power generation. This may cause a problem, that is, the river section from the barrage to the power station will cause a cut-off, and cause the extinction of aquatic organisms or the destruction of the ecological environment in this river section that depend on the river water for survival. ...
