Abstract
Description
Technical Field

Therefore, a pipeline-type hydroelectric power generation device with a filtration and diversion structure is proposed to avoid damage to the equipment's components caused by foreign objects.

A filter pipe is connected to one side of the bottom end of the L-shaped diversion pipe in the trapezoidal base, and a diversion pipe is connected to one side of the bottom end of the L-shaped diversion pipe corresponding to the filter pipe.
[0006] An inclined frame is installed at the top of the corresponding branch pipe between the L-shaped diversion pipe and the filter pipe. A filter screen is provided inside the inclined frame. The water turbine generator set includes an axial flow impeller.
[0007] By adopting the above technical solution, the L-shaped drainage pipe allows water to enter the trapezoidal base. The water entering the filter pipe is filtered by the filter screen inside the inclined frame, preventing foreign objects from entering with the water and avoiding damage to related equipment components due to foreign objects.
[0008] The slope facilitates the introduction of water into the funnel-shaped pipe, which flows to the axial flow impeller to make it rotate, so as to realize the function of converting mechanical energy into electrical energy when the hydro-generator unit is operating. At the same time, the main shaft of the hydro-generator unit is supported by the support bearing to avoid affecting its operation. The structure is simple and efficient.
[0009] The intercepted foreign objects and water are diverted through the diversion pipe, and the water is discharged through the drain pipe located at the bottom of the filter pipe and the diversion pipe.
[0010] Specifically, an L-shaped drainage pipe is inserted through the top of one side of the trapezoidal base, and a drain pipe is inserted through the bottom of one side of the trapezoidal base.
[0011] By adopting the above technical solution, water is introduced into the trapezoidal base using an L-shaped drainage pipe.
[0012] Specifically, the funnel-shaped pipe is installed on the inner wall of the filter tube and corresponds to the top of the axial flow impeller.
[0013] By adopting the above technical solution, a funnel-shaped pipe is used to facilitate the flow of water to the axial flow impeller.
[0014] Specifically, a ramp is installed between the top side of the funnel-shaped pipe and the inclined frame.
[0015] By adopting the above technical solution, a slope is used to facilitate the flow of water to the funnel-shaped pipe.
[0016] Specifically, the support bearing is installed inside the trapezoidal base at the top of the corresponding filter pipe, and the main shaft of the hydro-generator unit passes through the support bearing.
[0017] By adopting the above technical solution, the main shaft of the hydro-generator unit is supported by a support bearing while avoiding affecting its operation.
[0018] Specifically, the hydro-generator unit is bolted to one side of the top of the trapezoidal base, and the axial flow impeller is located at the bottom of the funnel-shaped pipe inside the filter tube.
[0019] By adopting the above technical solution, the water source is filtered by the filter screen inside the inclined frame on one side of the filter pipe.
[0020] The beneficial effects of this utility model are:
[0021] (1) The pipeline hydroelectric power generation equipment described in this utility model allows water to enter the trapezoidal base through an L-shaped diversion pipe. The water entering the filter pipe is filtered by the filter screen on the inside of the inclined frame to prevent foreign objects from entering with the water, thereby avoiding damage to the equipment components due to foreign objects.
[0022] (2) The pipeline hydropower generation equipment described in this utility model uses a slope to facilitate the introduction of water source into the inner side of the funnel-shaped pipeline and to make the axial flow impeller rotate, so as to realize the effect of converting the function into electrical energy under the operation of the hydro turbine generator set. At the same time, the main shaft of the hydro turbine generator set is supported by the support bearing to avoid affecting its operation. The structure is simple and efficient.
