Two-way cross flow pump station using one-way cross flow pump

Abstract

The invention discloses a two-way cross flow pump station using a one-way cross flow pump. The two-way cross flow pump station comprises a pump station main body; and a river channel is divided by thepump station main body into an inner river and an outer river. The two-way cross flow pump station is characterized by comprising an inner river first gate and an inner river water inlet gate near the inner river, and an outer river drainage gate and an outer river second gate near the outer river; the inner river first gate communicates with the outer river drainage gate through a first water channel; and the outer river second gate communicates with the inner river water inlet gate through a second water channel. The two-way cross flow pump station further comprises a separator for isolating the first water channel from the second water channel; the separator is provided with an exchange channel for communicating the first water channel with the second water channel; the one-way cross flow pump is arranged in the exchange channel; a water outlet end of the one-way cross flow pump is towards the first water channel; and a water inlet end of the one-way cross flow pump is towards thesecond water channel. The invention aims to solve the defects in the prior art, and provides the two-way cross flow pump station for direct reversing drainage by using the one-way cross flow pump without changing the direction of the one-way cross flow pump.

Description

technical field [0001] The invention relates to the field of two-way through-flow pumping stations, in particular to a two-way through-flow pumping station using a one-way through-flow pump. Background technique [0002] Two-way through-flow pumping stations are widely used, for example, internal and external river pumping stations with both irrigation and drainage functions, urban inland rivers with two-way ecological cycle water supply requirements, and water conservancy projects with both flood control and drainage. [0003] When the water level of the outer river is higher than that of the inner river, diverting the water from the outer river to the inner river is called self-irrigation; draining the water from the inner river to the outer river is called lifting; [0004] When the water level of the inner river is higher than that of the outer river, diverting the water from the outer river to the inner river is called lifting irrigation; discharging the water from the ...

Problems solved by technology

[0009] Secondly, in order to ensure the opening and closing angle of the existing flap door, the method of reducing its own weight is usually used to reduce the water energy loss; In the middle, it will cause the anti-rust layer on the surface of the hinged section to be worn, resulting in corrosion and rust of the hinged section, which will make it difficult to open or close the flap after opening.

Simply increasing the self-weight of the flap will lead to the consumption of more water energy to offset the self-weight of the flap and reduce the drainage efficiency, and it cannot fundamentally solve the problem of water energy consumption directly caused by the excessive weight of the flap
