Special efficient and energy-saving flood drainage pump station for hydraulic engineering

Abstract

The invention discloses a special efficient and energy-saving flood drainage pump station for hydraulic engineering in the technical field of flood drainage equipment, which comprises a water pump and a water pipe. The water pipe is composed of a first water pipe branch and a second water pipe branch. The water outlet end of the water pump is fixedly connected with the first water pipe branch. An anti-blocking mechanism is fixedly connected between the end, away from the water pump, of the first water pipe branch and the second water pipe branch. The anti-blocking mechanism is composed of an anti-blocking box and a filtering layer detachably installed in the anti-blocking box. A cleaning mechanism is arranged on the left side of the filtering layer, a driving mechanism used for driving the cleaning mechanism to reciprocate up and down is connected to the cleaning mechanism, and an air cylinder used for providing a power source is connected to the driving mechanism. During use, the air cylinder can drive straight plate teeth to move left and right, and then a cleaning roller is driven by a reciprocating rod to move back and forth, so that the cleaning roller cleans the filtering layer, and blockage can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of drainage equipment, in particular to a high-efficiency and energy-saving drainage pumping station for water conservancy projects. Background technique [0002] When the existing drainage pump station discharges water to the outside of the dam, in order to compensate for the pressure difference caused by the lifting of the water, it is necessary to install a booster device on the inside of the dam, and increase the water lifting capacity by inputting electric energy to use the equipment, so as to ensure the safety of the drainage pump station. Drainage efficiency increases the consumption of electric energy, and when the drainage pump pumps water, it cannot filter the sediment and stones in the water, thereby increasing the viscosity of the water, thereby reducing the head of the drainage pump and increasing the energy. Especially in the process of drainage, impurities will block the filter layer, making i...

Problems solved by technology

[0002] When the existing drainage pump station discharges water to the outside of the dam, in order to compensate for the pressure difference caused by the lifting of the water, it is necessary to install a booster device on the inside of the dam, and increase the water lifting capacity by inputting electric energy to use the equipment, so as to ensure the safety of the drainage pump station. Drainage efficiency increases the consumption of electric energy, and when the drainage pump pumps water, it cannot filter the sediment and stones in the water, thereby increasing the viscosity of the water, thereby reducing the head of the drainage pump and increasing the energy. Especially in the process of drainage, impurities will block the filter layer, making it difficult to discharge water, which in turn leads to a decrease in drainage efficiency
