DETAILED DESCRIPTION

[0019] The following is a specific embodiment of the utility model and further describes the technical scheme of the utility model in combination with the drawings, but the utility model is not limited to these embodiments.

[0020] For example, Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, this deep well protective submersible pump includes a submersible pump body 1. The pump casing of the submersible pump body 1 has an axially extending regular hexagonal prism structure, with arc transition sections 2 at the six side edges. Each side plane has an axially extending mounting groove 3, and a detachable protective component 4 is embedded in each mounting groove 3. The protective component 4 includes a connecting block 5 that matches the shape of the mounting groove 3. The outer surface of the connecting block 5 has a grid-like shock-absorbing protrusion 6. T-shaped guide rail holes 7 are symmetrically opened on the side walls at both ends of the mounting groove 3. A top block 8 is slidably fitted in each guide rail hole 7. The top block 8 is driven to move axially by a bolt post 9 with a precision threaded engagement. The end of the bolt post 9... The connecting block 5 is equipped with an anti-slip textured operating head. Both ends of the connecting block 5 have connecting structures, including a T-shaped movable cavity 10 within the connecting block 5, a connecting part 11 slidably disposed within the movable cavity 10, an elastic element 12 located within the T-shaped movable cavity 10 for elastic reset, and a detachable baffle 13. The baffle 13 is installed at the end of the connecting block 5 by fastening bolts. Under the action of the elastic element 12, the connecting part 11 partially extends out of the movable cavity 10 and embeds into the guide rail hole 7 to form a radial limit. By tightening the bolt post 9, the top block 8 is driven to axially press the connecting part 11, causing it to retract completely into the movable cavity 10, thereby enabling the disassembly of the protective element 4. The elastic element 12 can be a butterfly spring with a preload of 50-80N, and both ends of the spring have guide posts to prevent deflection. The axial ends of the protective element can be arranged in an arc structure. The depth of the mounting groove 3 is 2 / 3-4 / 5 of the thickness of the connecting block 5, and the bottom surface of the mounting groove 3 is provided with a rubber buffer pad that is interference-fitted with the connecting block 5.

[0021] The pump casing structure, combined with the arc transition design, balances mechanical strength and hydrodynamic performance, making it suitable for high-pressure environments in deep wells. The protective component 4 can be independently disassembled and replaced, reducing maintenance costs. The triple shock absorption design of the shock-absorbing protrusion 6, rubber buffer pad, and butterfly spring significantly extends the service life of the submersible pump and the protective component 4. The linkage mechanism between the T-shaped guide rail hole 7 and the top block 8 enables "one-click" disassembly and assembly. The anti-slip textured operating head facilitates manual operation without additional tools, improving maintenance efficiency.

[0022] Working principle

[0023] The pump shell adopts a regular hexagonal prism structure, six side edges are provided with arc transition parts 2, the overall compression and torsion resistance is enhanced, and the water flow resistance is reduced. A detachable protection piece 4 is embedded in an axial installation groove 3, a grid-shaped shock-absorbing protrusion 6 is arranged on the outer surface of the protection piece 4, vibration energy is dispersed and impact force is absorbed, noise and wear caused by water flow or mechanical vibration during operation of the submersible pump are reduced. A top block 8 is arranged in a T-shaped guide rail hole 7 at the two ends of the installation groove 3, the top block 8 is driven to move axially by rotating a non-slip bolt column 9. When the top block 8 moves axially, the elastic piece 12 (such as a butterfly spring) of the connecting part 11 of the protection piece 4 is pressed, the connecting part 11 is forced to retract into the movable cavity 10, the radial limiting is released, and the protection piece 4 is quickly disassembled. The connecting structure of the protection piece 4 is provided with a butterfly spring (pre-tightening force 50-80N) and a guide column, so that the elastic piece 12 is stably reset when pressed, and deviation is avoided. The pressing force of the top block 8 on the connecting part 11 can be controlled by rotating the bolt column 9, so that the protection piece 4 is automatically locked (the elastic piece 12 pushes the connecting part 11 to be embedded in the guide rail hole 7 for limiting) during installation, and is released by one key during disassembly, without the need for complex tools. Rubber buffer pads are arranged on the bottom surface of the installation groove 3, and are in interference fit with the connecting block 5, further absorbing vibration and preventing the protection piece 4 from loosening. The arc structure at the two axial ends of the protection piece 4 optimizes water flow guidance, reduces the impact of turbulent flow on the pump body, and reduces the risk of sediment accumulation.
