Abstract

The invention relates to a drainage pumping station of a deep drainage tunnel system. The drainage pumping station comprises a front water pool and a drainage assembly partially arranged in the front water tank. The drainage assembly comprises a grid-shaped flow guide wall, a water pump water suction pipe, a water pump, a baffle and a water pressing plate; the grid-shaped flow guide wall is arranged in the front water tank, one side of the grid-shaped guide wall is connected with the inner wall of the front water tank, and the grid-shaped flow guide wall is provided with a plurality of cavities communicating with the front water tank; a water inlet of the water pump water suction pipe extends into the cavities, and a water outlet of the water pump water suction pipe communicates with the water pump; the baffle is arranged on the side, away from the inner wall of the front water tank, of the grid-shaped flow guide wall; one end of the water pressing plate is connected to the bottom of the baffle, and the other end of the water pressing plate inclines towards the water pump water suction pipe, so that a flow guide channel is formed between the face, facing the bottom wall of the front water tank, of the water pressing plate and the bottom wall of the front water tank, water flow in the front water tank is guided to the water inlet through the flow guide channel, and the situation that vortex is formed at the water inlet of the water suction pipe of the water pump or around the baffle to affect the operation efficiency and the service life of the water pump is avoided.

Description

technical field [0001] The present disclosure relates to the technical field of drainage, in particular to a drainage pumping station for a deep drainage tunnel system. Background technique [0002] The drainage pump station of deep drainage tunnel system is an important part of the deep drainage tunnel system, which undertakes the drainage task of the entire tunnel drainage system. Whether its operation status is good or not directly affects the operation status of the tunnel system. The drainage pumping station of the deep drainage tunnel system generally includes the forebay, water pump, etc. [0003] However, due to the different water levels in the forebay of the drainage pump station of the deep drainage tunnel system under different working conditions, the flow of water from the deep drainage tunnel into the sump of the pump station will carry water kinetic energy, and the flow state of the water flow at the water inlet of the pump is disordered and easily The vortex...
