A high-efficiency and energy-saving drainage pumping station for water conservancy projects

Abstract

The invention relates to the field of water conservancy engineering equipment, in particular to a high-efficiency and energy-saving drainage pumping station for water conservancy projects, which converts the wave energy of the water body through an energy-harvesting mechanism and drives a booster cylinder to pressurize the suction pipe, and pump water generated by the drainage pump. The pressure difference plays a compensatory role, and no power input is required, thereby reducing energy consumption while improving drainage efficiency, achieving the purpose of energy saving, and the energy-harvesting mechanism can block larger stones, and improve the protection against dams and suction pipes. And the protective ability of the sand filter tube, and use the sand filter tube to filter the sediment from the water entering the suction pipe, improve the lift capacity of the drainage pump, reduce energy consumption, further play a role in energy saving, and at the same time increase the service life of the drainage pump , and the pressurized cylinder can also backwash the sand filter cylinder to maintain the high-efficiency filtering effect of the sand filter cylinder. The energy-harvesting mechanism can also drive the sand discharge mechanism to clean the sediment and rocks at the bottom of the dam, saving time Save effort and ensure the normal operation of the entire drainage pumping station.

Description

technical field [0001] The invention relates to the field of water conservancy engineering 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. In addition, the sediment in the water will also cause blockage of the water...

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. Consumption, and the sediment in the water will also cause blockage of water pipes and damage to the impeller of the drainage pump, thereby reducing the service life of the drainage pump. In view of this, we propose a high-efficiency and energy-saving drainage pumping station for water conservancy projects
