Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy infrastructure equipment, in particular to a low water level working cooling device for a submersible pump. Background Art

[0002] Submersible pumps are important equipment for water discharge and transfer. When in use, the entire unit is submerged in water, water enters from the bottom of the submersible pump, and is then discharged from the outlet pipe of the submersible pump. It has a wide range of applications, including mine rescue, construction drainage, agricultural water irrigation and drainage, industrial water circulation, drinking water supply for urban and rural residents, and even disaster rescue, etc. Construction in the rainy season is a seasonal construction that needs to be focused on in construction projects. When a submersible pump is used for on-site pumping and the water level cannot completely cover the pump body, the pump body is more likely to overheat and be damaged, causing property losses in the project.

[0003] The patent with the publication number CN215890600U discloses a submersible pump anti-dry-burn water sprinkling cooling system. In this scheme, the water outlet of the submersible pump body is connected to the inlet end of the submersible pump drainage pipe. Each set of anti-dry-burning mechanism is connected to the submersible pump drainage pipe through a connecting joint. The anti-dry-burning mechanism includes a drainage diversion pipe, a valve, a valve operating rod and a floating plate; the drainage diversion pipe is connected to the submersible pump drainage pipe through a connecting joint, and the inlet end of the drainage diversion pipe is provided with a valve, one end of the valve operating rod is connected to the control end of the valve, and the other end of the operating rod is hinged to the floating plate, and a shower is connected to the pipe wall of the drainage diversion pipe. The water discharged by the submersible pump is passed into the shower after diversion, and the pump body of the submersible pump is cooled after being sprayed out by the shower. However, when the submersible pump is in use, since the water sprayed by the shower will flow back to the location of the submersible pump, it is easy to cause the problem of low drainage efficiency of the submersible pump while ensuring that the submersible pump has a sufficient cooling effect. Utility Model Content

[0004] The utility model provides a low water level working cooling device for a submersible pump, which solves the problem of low drainage efficiency of the submersible pump when draining water at a low water level in the prior art.

[0005] The technical solution of the utility model is achieved in this way:

[0006] A submersible pump low water level working cooling device comprises a submersible pump body, a water outlet of the submersible pump body is connected with a drain pipe and a cooling water pipe at the same time, the outlet of the cooling water pipe is connected with a water spray piece corresponding to the submersible pump body, and the pipe diameter of the drain pipe is larger than the pipe diameter of the cooling water pipe. The water pumped out by the submersible pump is simultaneously passed into the drain pipe and the cooling water pipe, and the water in the cooling water pipe is discharged through the water spray piece to cool the submersible pump body, and because the pipe diameter of the cooling water pipe is smaller than the pipe diameter of the drain pipe, the water entering the cooling water pipe is less than the water entering the drain pipe, so that most of the water pumped out by the submersible pump is discharged, and a small part is used to cool the submersible pump body, thereby improving the drainage efficiency of the submersible pump.

[0007] The water outlet is connected to the inlet of the three-way pipe joint, and the drain pipe and the cooling water pipe are connected to the outlet of the three-way pipe joint. The water outlet, drain pipe and cooling water pipe of the submersible pump are connected through the three-way pipe joint, and the three-way pipe joint can be detachably connected to the water outlet, which is convenient for installing the cooling device on the submersible pump.

[0008] A valve is provided between the cooling water pipe and the three-way pipe joint. The valve is used to control the on-off of the water flow in the cooling water pipe. Specifically, when the water level is low and cannot completely cover the submersible pump body, the valve is opened to cool the pump body and dissipate heat; when the water level can completely cover the submersible pump body, the valve is closed, and all the water pumped out by the submersible pump is discharged through the drain pipe to ensure the drainage efficiency of the submersible pump.

[0009] A reducer is provided between the cooling water pipe and the three-way pipe joint. The diameter of the reducer's inlet port is larger than the diameter of the reducer's outlet port. The cooling water pipe is connected to the outlet port of the reducer so that the amount of water entering the cooling water pipe is less than the amount of water entering the drain pipe.

[0010] The cooling water pipe is a U-shaped pipe, one end of which is connected to a three-way pipe joint, and the other end of which is connected to a water spraying member, which is located above the submersible pump body. The water pumped out by the submersible pump passes through the U-shaped pipe and is sprayed from above the submersible pump, thereby cooling and dissipating the submersible pump body.

[0011] The submersible pump body or the water spraying part is provided with a fan blade, and the fan blade corresponds to the outlet of the water spraying part. The water sprayed by the water spraying part impacts the fan blade, and the fan blade breaks up the sprayed water into water mist, thereby increasing the contact area between the water and the submersible pump body and improving the cooling and heat dissipation efficiency of the submersible pump.

[0012] The fan blade includes a bracket and a blade, the blade is rotatably arranged on the bracket, and the bracket is connected to the pump body or the water spraying part of the submersible pump. The water sprayed by the water spraying part impacts the blade, so that the blade rotates on the bracket, and the air flow near the pump body is stirred during the rotation of the blade, thereby improving the heat dissipation efficiency; and the blade can disperse the water sprayed by the water spraying part to form water mist, thereby increasing the contact area between the water and the pump body and improving the heat dissipation efficiency.

[0013] A handle is provided on the top of the submersible pump body, and the bracket is arranged on the handle. The handle is convenient for the staff to lift the submersible pump and is convenient for moving the submersible pump.

[0014] The bottom of the submersible pump body is provided with a water inlet, and the submersible pump pumps water out through the bottom water inlet. The water spraying part is a shower head or a spray head. The water sprayed by the shower head or the spray head is more uniform, ensuring full contact between the water and the pump body.

[0015] The beneficial effect produced by the utility model is that the diameter of the drainage pipe is larger than the diameter of the cooling water pipe, so that the amount of water entering the cooling water pipe is smaller than the amount of water entering the drainage pipe, so that most of the water pumped out by the submersible pump is discharged through the drainage pipe, and a small part of the water is dissipated and cooled by the cooling water pipe to dissipate heat and cool the submersible pump body, thereby ensuring sufficient cooling effect while ensuring the drainage efficiency of the submersible pump.

[0016] Blades are provided at the outlet of the water spray component. The water sprayed by the water spray component impacts the blades, causing the blades to rotate, thereby causing the air near the pump body to flow, thereby improving the heat dissipation efficiency. The blades can also disperse the water sprayed by the water spray component to form water mist, thereby increasing the contact area between the water and the pump body, thereby further improving the heat dissipation efficiency.
