Abstract

The invention discloses a multi-layer guide rail type multifunctional composite trash rack, which comprises a guide rail main body, a trash rack, a bar direction controller, a screen frame, and a cleaning mechanism. Wherein, the main body of the guide rail is located at the front side of the water inlet of the water turbine and its end wall is fixed to the side wall of the water inlet of the water turbine. Cleaning tank, wherein the screen frame slot is used to set the screen frame, and the trash rack slot is used to set the pollution cleaning mechanism; the invention has the functions of silting up the water inlet, grading and blocking dirt according to the size and direction of the dirt, The trash rack is easy to clean, can remove floating objects on the water surface above the trash rack, can prevent dirt from entering the turbine when the trash rack is replaced, and can prevent fish from entering the turbine, etc. It has strong practicability and multiple functions, and can solve many thorny problems faced by current hydropower stations. It can be applied to hydropower stations that have been built or are under construction.

Description

technical field [0001] The invention belongs to the technical field of sewage blocking and cleaning equipment for hydropower projects, and in particular relates to a sewage blocking and cleaning device that can be used for water inlets of hydropower stations and pumping stations. Background technique [0002] With the increase of torrential rains and floods in my country, the design of a large number of existing trash racks of hydropower stations has exposed many shortcomings, such as easy deposition of sediment near the water inlet where the water flow is slow, easy blockage of trash racks, inconvenient replacement and cleaning of trash racks, etc. . When the trash rack needs to be replaced urgently due to the large amount of garbage in the flood, the existing trash rack cannot play the role of trash rack while being replaced. During the replacement process, a large amount of dirt may enter the turbine, which can easily damage the turbine. If the trash rack is not replaced...
