Unpowered sewage disposal device used for hydropower station

Abstract

The invention discloses an unpowered sewage disposal device used for a hydropower station, and belongs to the technical field of riverway sewage disposal equipment. The unpowered sewage disposal device is characterized by being mainly composed of a sewage disposal platform, a fixed frame, an elastic tensioning mechanism, a chain type conveying device and conveying teeth, wherein the sewage disposal platform is arranged on the water surface, the fixed frame is arranged on a pier on a water release gate of the hydropower station, the elastic tensioning mechanism is arranged on the fixed frame, the chain type conveying device is arranged between the elastic tensioning mechanism and the sewage disposal platform, and the conveying teeth are distributed on the conveying face of the chain type conveying device. The sewage disposal platform is connected with an external support through a connecting element, the end, located on one side of the sewage disposal platform, of the chain type conveying device stretches below the water surface, a transmission mechanism is arranged on the sewage disposal platform, and the power input end of the transmission mechanism is connected with a first propeller located in water, the power output end of the transmission mechanism is connected with the chain type conveying device, and the included angle between the rotating axis of the first propeller and the water flowing direction is 0 degree-45 degrees. The unpowered sewage disposal device used for the hydropower station is reasonable in structure, good in sewage disposal effect and convenient to use and is used for riverway sewage disposal.

Description

technical field [0001] The invention relates to a decontamination device, more specifically, to a non-powered decontamination device for a hydropower station. Background technique [0002] With the development of society and the increasing urban population, more and more domestic waste is produced, which has a greater impact on the water quality of the river and the environment. At the same time, the hydropower stations and sluices built on the river are also deeply affected by the waste. On the one hand, a large amount of garbage has been concentrated in the trash buoys on the water surface of the water inlet of the hydropower station for a long time, which has a great impact on the surrounding environment. If you want to clean up thoroughly, you have to use boats to salvage continuously (because the upstream garbage continues to flow down with the water), or open the sluice gate of the hydropower station to discharge the garbage downstream through the water flow, but when ...

Problems solved by technology

[0002] With the development of society and the increasing population of cities, more and more domestic garbage is produced, which has an increasing impact on the water quality of rivers and the environment. At the same time, hydropower stations and sluices built on rivers are also deeply affected by garbage. On the one hand, a large amount of garbage has been concentrated in the trash buoys on the water surface of the water inlet of the hydropower station for a long time, which has a great impact on the surrounding environment

If you want to clean up thoroughly, you need to use boats to salvage continuously (because the upstream garbage continues to flow down with the water), or open the sluice gate of the hydropower station to discharge the garbage downstream through the water flow, but when the water is not enough , it is impossible to discharge the garbage through this method; on the other hand, the garbage overturns the trash buoy and enters the forebay and is blocked at the trash rack of the water inlet, which seriously affects the output of the hydropower unit and the efficiency of the power station. The cleaning of the garbage is often difficult. Expend huge human and financial resources

[0003] Almost all existing cleaning equipment adopts manual cleaning methods, some use grab-type cleaning devices, and some use door-type cleaning devices. When there is a lot of garbage in the wet season, these cleaning devices all use a large number of Manpower and material resources are required to operate for a long time, and the efficiency is low, and the labor intensity of personnel is high. A lot of garbage is sucked into the trash rack by water during power generation and cannot be cleaned. To clean it thoroughly, it must be shut down to clean it up.

Moreover, the cleaned up garbage is piled up on the cleaning platform, and it must be cleaned up or reloaded a second time, which costs a lot of manpower and material resources.
