Decontamination system for water inlet of hydropower station

Abstract

The invention discloses a sewage cleaning system for a water inlet of a hydropower station, which comprises a floating interception belt device located upstream of the water inlet of a hydropower station and a salvage ship for salvaging garbage. The floating interception belt device is composed of several floating devices connected in series. The device consists of an upper open metal box and an empty cylinder for generating buoyancy. The invention makes full use of the floating interception belt device arranged at the water inlet, intercepts the floating garbage at the upstream of the water inlet of the hydropower station in advance, and then salvages and discharges the garbage through the salvage ship, effectively reducing the trash arresting pressure at the trash rack of the hydropower station .

Description

technical field [0001] The invention relates to a sewage cleaning system for water conservancy projects, in particular to a sewage cleaning system for a water inlet of a hydropower station. Background technique [0002] With the growth of my country's economy, the lives of residents have been improved, and people's material life has been satisfied. However, in the process of development, due to the lack of environmental pollution control, the rivers and lakes in our country have been polluted to varying degrees. All kinds of garbage and floating objects can be seen everywhere on the water. If these garbage are not rectified, they will bring unexpected disasters to aquatic organisms. [0003] At present, the construction of hydropower stations provides electricity for people's production and life, and the generator water inlet group of hydropower stations is an important part of the power system. Whether it can work normally is an important link to ensure normal power supply. ...

AI Technical Summary

Problems solved by technology

Because people do not pay attention to environmental protection, they discharge a large amount of domestic garbage and other garbage into the river, resulting in a particularly large amount of garbage in the river. The trash rack is under increasing pressure to intercept dirt, which results in frequent cleaning of garbage at the trash rack. If there is too much garbage, it is likely to damage the trash rack when cleaning the trash at the water inlet

In addition, the decomposition of some floating objects in the water may cause a certain degree of corrosion to the trash rack, which has a great impact on the durability of the trash rack

[0004] Due to the blockage of the dam, the floating objects stay in the upper reaches of the reservoir. Over time, a large amount of garbage will be stranded in the upper reaches of the dam, which is not only unsightly, but also may bring a lot of pollution to the water body, the environment, the air, etc. Due to the effect of floating debris, it will also bring some obstacles to the navigation of ships. The treatment of floating debris has always been carried out by manual salvage. This cleaning method is time-consuming, laborious, costly, and inefficient. High, and has certain security risks
