Single-channel multi-stage water power generation device

Abstract

The invention discloses a single-channel multi-stage water power generation device. The single-channel multi-stage water power generation device structurally comprises a movable door, slots, a power generation source dredging device, a water power generation shell, a bottom plate, a multi-scale hydrodynamic group and a converting power generation mechanism, wherein the converting power generationmechanism is fixedly mounted at one end, away from the power generation source dredging device, of the inner top end of the water power generation shell; the bottom end of the water power generation shell is fixedly connected to the top end of the bottom plate in a welding manner; the bottom end of the multi-scale hydrodynamic group is mounted at the top end of the bottom plate in an embedded manner; one end, away from the bottom plate, of the multi-scale hydrodynamic group is mounted at one end, near the bottom plate, of the converting power generation mechanism in an embedded manner. According to the invention, a hydraulic triggering mechanism is mainly utilized for controlling the energization state of an auxiliary power mechanism, and when a filter screen blocks too much sundries, a water flow cannot enter a communicating pipe, the hydraulic triggering mechanism passively triggers and controls energization of the auxiliary power mechanism, a dredging mechanism cleans the filter screen and cleaned materials are collected into a collecting mechanism, so that automatic cleaning can be achieved without manual operation.

Description

technical field [0001] The invention relates to the field of hydropower generation, in particular to a single-canal multi-stage hydropower generation device. Background technique [0002] Hydropower is a science and technology that studies technical and economic issues such as engineering construction and production operation that convert water energy into electrical energy. The water energy used by hydropower is mainly the potential energy stored in water bodies. In order to convert water energy into electrical energy, it is necessary Construct different types of hydropower stations. [0003] The existing single-canal multi-stage hydroelectric power generation device has a large amount of water inflow and a lot of debris in the water. If the debris is not blocked and filtered, the debris is easy to wrap around the rotating shaft of the water wheel. When there are too many debris wrapped around the rotating shaft, the speed It will reduce or even shut down, and if the debri...

[0003] The existing single-canal multi-stage hydroelectric power generation device has a large amount of water inflow and a lot of debris in the water. If the debris is not blocked and filtered, the debris is easy to wrap around the rotating shaft of the water wheel. When there are too many debris wrapped around the rotating shaft, the speed It will reduce or even shut down, and if the sundries are blocked, it is easy to cause danger due to the excessive water pressure caused by the impact of the water flow
