Description

Technical Field

[0001] The utility model relates to the technical field of gate pumps, in particular to a gate pump provided with a flow splitting and pressure relief structure. Background Technique

[0002] A pumping station is a device and project that can provide hydraulic power and pneumatic power with a certain pressure and flow rate, which is called pumps and pumping station projects. It is the general name of the intake, outlet, pump house and other buildings of a drainage and irrigation pumping station, and the valve pump is an essential equipment for the pumping station. However, the existing valve pumps have some deficiencies. For example:

[0003] For a gate pump disclosed in the publication number: CN101305875A, since the device only adjusts the pressure balance inside and outside the gate by means of a water pump, once the rainfall is large during use, it will cause the pressure of the pump machine to increase. And the flow rate of the pump machine has a certain upper limit. When the pressure difference between the inside and outside ends is too large and the gate is not provided with a flow splitting device, it will cause huge pressure on the entire pumping station. Once the water flow gets out of control, the pumping station will be washed away, causing safety problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a gate pump provided with a flow splitting and pressure relief structure, so as to solve the problems in the above background technique that the existing devices on the market only adjust the pressure balance inside and outside the gate by means of a water pump. Once the rainfall is large during use, it will cause the pressure of the pump machine to increase. And the flow rate of the pump machine has a certain upper limit. When the pressure difference between the inside and outside ends is too large and the gate is not provided with a flow splitting device, it will cause huge pressure on the entire pumping station. Once the water flow gets out of control, the pumping station will be washed away, causing safety problems.

The heat sink 2 is fixedly connected to the upper and lower sides of the third waterproof motor 16, which can provide high-efficient heat dissipation efficiency when the third waterproof motor 16 is running, thereby improving the operation efficiency of the device.

[0028] Working principle: When using the gate pump with a diversion and pressure-relief structure, first lay the device in a suitable position. When the water flow is insufficient, water can be stored through natural flow. When the flood season comes and the water level rises significantly, the flow-limiting gate 4 will be lifted by the hydraulic pump 8 and the first waterproof motor 9 to drive the hydraulic rod 7, realizing floodgate opening and water discharge. At the same time of waterproofing, the pump impeller 13 and the second waterproof motor 15 will also run synchronously to improve the drainage efficiency. When the water level reaches the diversion pipeline 3, the third waterproof motor 16 and the pump blade 17 on both sides of the flow-limiting gate 4 will run synchronously to increase the drainage efficiency and divert the water flow in a high-throw manner to reduce the impact of high-velocity water on the pump station.

[0029] Thus, a series of operations are completed. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
