Embodiment 1

[0056] figure 1 and 2 Shown is an embodiment of the two-way drainage pump gate of the present invention. The two-way drainage pump gate includes a gate 1, a sleeve 17, a pump barrel 16, a horizontal axial flow pump 13, a water inlet pipe 4, and a water outlet pipe 6. , water inlet control valve 10 and water outlet control valve 11;

[0057] The sleeve 17 is installed in the gate 1 , preferably, the sleeve 17 is installed at the inner center lower position of the gate 1 through a flange connection.

[0058] The pump barrel 16 is installed in the sleeve 17;

[0059] The horizontal axial flow pump 13 is installed in the pump barrel 16;

[0060]The water inlet pipe 4 is installed in the gate 1, one end of the water inlet pipe 4 is provided with a second water inlet flap 26, and the other end is connected to the water inlet of the horizontal axial flow pump 13 through a pipeline;

[0061] The water outlet pipe 6 is installed in the gate 1, one end of the water outlet pipe 6 is ...

Embodiment 2

[0084] A two-way drainage pump gate control system, comprising the two-way drainage pump gate and controller in Embodiment 1;

[0085] The controller is respectively connected with the gate (1), the horizontal axial flow pump (13), the liquid level sensor (106), the first water inlet flapper door (8), the first water outlet flapper door (9), and the second inlet flapper door (9). The water flapping door (26), the second water outlet flapping door (27), the water inlet control valve (10) and the water outlet control valve (11) are connected.

[0086] When the water flow submerges the impeller of the horizontal axial flow pump 13 , the liquid level sensor 106 detects the liquid level signal and transmits it to the controller, and the controller controls the horizontal axial flow pump 13 to work.

[0087] When the right side enters water and the left side exits: the controller controls the gate 1 to close, opens the first water inlet flap gate 8 and the first water outlet flap ga...

Abstract

The invention provides a bidirectional draining pump brake and a control system. The bidirectional draining pump brake comprises a gate, a sleeve, a pump cylinder, a horizontal type axial flow pump, awater inlet pipe, a water outlet pipe, a water inlet control valve, a water outlet control valve and a control circuit. The pipes are integrally horizontally mounted. The sleeve is mounted inside thegate. The pump cylinder is mounted in the sleeve. The horizontal type axial flow pump is mounted in the pump cylinder. The water inlet pipe is mounted in the gate. One end of the water inlet pipe isprovided with a secondary water inlet flap valve, and the other end of the water inlet pipe is connected with a water inlet of the horizontal type axial flow pump. A pipe water inlet is formed in a pipe between the water inlet control valve and the horizontal type axial flow pump and provided with a first water inlet flap valve. A pipe water outlet is formed in a pipe between the water outlet control valve and the horizontal type axial flow pump and provided with a first water outlet flap valve. The bidirectional draining pump gate is good in reliability and convenient to implement; plenty ofland investment is saved, and the labor intensity is lowered; and meanwhile, the problem that operation efficiency is low due to use of a bidirectional operation flap valve is avoided.

Description

technical field [0001] The invention belongs to the technical research field of pump gates for water conservancy projects, and particularly relates to a two-way drainage pump gate and a control system. Background technique [0002] The integrated pump gate structure is different from the traditional pump gate structure. The submersible axial flow pump is directly installed on the sluice gate through the connection structure, and the submersible axial flow pump and the sluice gate are combined into one. It also has the advantages of no need for upper plant structure, simplified hydraulic structure, reduced floor space, and reduced engineering investment. [0003] In the case of two-way outflow of a single pump, two-way axial flow pumps or tubular pumps are often used. This type of pump has high efficiency in forward operation and very low efficiency in reverse operation. [0004] In the prior art, the vertical submersible axial flow pump double-layer two-way flow channel sys...
