It is mainly composed of a pump body, a motor, a drive shaft, a mechanical seal or a packing seal, etc. It is usually used to transport liquids, including groundwater, well water, seawater, and various industrial liquids.

[0003] The main functions of submersible pumps include: Lifting liquids: Submersible pumps can transport liquids from deep wells or underwater to the ground to meet the needs of irrigation, water supply, industrial production, etc. Sewage treatment: In the sewage treatment industry, submersible pumps are mainly used to treat sewage, helping to move wastewater and transfer it to treatment equipment for treatment. Seawater desalination: In the seawater desalination industry, submersible pumps are mainly used to provide raw water to the desalination device. Petroleum and chemical industry: In the petroleum industry, submersible pumps are often used to obtain crude oil and natural gas, safely raising these liquids from the bottom of the well to the ground. In the chemical industry, submersible pumps are mainly used to transport highly concentrated acidic or alkaline liquids, such as sulfuric acid, hydrofluoric acid, sodium hydroxide, etc.

[0004] However, in actual use of the prior art, since the submersible pump is usually composed of a pump body, a motor, a drive shaft, a mechanical seal or a packing seal, the volume and length of the submersible pump are relatively large, so that when the submersible pump is in use, it needs to be supported and fixed on the upper end of the well body by mounting bolts to maintain the stability of the submersible pump. However, when the liquid level to be transported decreases, it will be inconvenient to adjust the insertion depth of the pump body of the submersible pump that is supported and fixed by mounting bolts. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: comprising a pump body and a mounting base plate, a support platform is welded to the upper end of the mounting base plate, a main limit sliding hole and a secondary limit sliding hole are respectively opened in the middle and side ends of the upper end surface of the support platform, a support plate is fixedly installed on the outer curved surface of the upper end of the pump body, and support limit sliding holes and internal threaded holes are respectively opened on both side ends of the support plate, and the inner wall of the support limit sliding hole is movably connected to the limit sliding rod;

[0008] Preferably, mounting holes are formed through the four corners of the mounting base plate, and there are four mounting holes, which are symmetrically distributed at the four corners of the mounting base plate, so that the mounting base plate can be installed and fixed through the mounting holes in conjunction with mounting bolts.

[0009] Preferably, the lower end of the pump body is movably connected to the inner walls of the main limit sliding hole and the auxiliary limit sliding hole respectively.

[0010] Preferably, the lower top end of the limiting slide bar is fixedly installed on the upper side end of the support platform.

[0011] Preferably, the top transmission shaft portion of the driving motor is rotatably connected to the top side end of the support platform via a rotating shaft.

[0012] Preferably, the lower end of the transmission screw is rotatably connected to the end of the support platform away from the limiting slide rod through a rotating shaft, and the upper end of the transmission screw is threadedly connected to the inner wall of the internal threaded hole.

[0013] Preferably, the transmission screw and the limiting slide rod are respectively fixedly mounted with limiting blocks for limiting the support plate on their upper top ends.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

When the first transmission sprocket rotates, it will drive the second transmission sprocket to rotate through the chain. When the second transmission sprocket rotates, it will drive the transmission screw to rotate. When the transmission screw rotates, the force generated by the threaded connection with the upper end of the transmission screw on the inner wall of the internal threaded hole will drive the support plate to move up and down.

When the support plate moves up and down in a linear manner, it will drive the pump body to move up and down in a linear manner along the main limit sliding hole and the auxiliary limit sliding hole, so as to realize the function of adjusting the insertion depth of the pump body by controlling the start of the driving motor.
