Description

Technical Field

[0001] The utility model mainly relates to the field of submersible pumps, in particular to an anti-clogging submersible pump. Background Art

[0002] Submersible pumps are important equipment for deep well water extraction. When in use, the entire unit submerges in the water to extract groundwater to the surface for domestic water, mine rescue, industrial cooling, farmland irrigation, seawater lifting, ship loading, and fountain landscape.

[0003] Hot water submersible pumps are used for hot spring bathing, and can also be used to extract groundwater from deep wells, and can also be used in water extraction projects such as rivers, reservoirs, and canals. They are mainly used for farmland irrigation and water for people and livestock in high mountainous areas. They can also be used for central air conditioning cooling, heat pump units, cold pump units, cities, factories, railways, mines, and construction site drainage. The general flow rate can reach 5-650m³ / h and the head can reach 10-550 meters.

[0004] The inventor discovered the following defects during the operation of the specific embodiment:

[0005] When the submersible pump is installed in a deep well, it is fixed with ropes. However, the submersible pump will shake during operation, and the ropes cannot limit the submersible pump, causing the shaking submersible pump to collide with the wall of the deep well, causing damage to the submersible pump.

[0006] It should be noted that the above contents belong to the technical cognition scope of the inventor. Since the technical contents in this field are vast and too complicated, the above contents of this application do not necessarily constitute prior art. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0031] See attached Figure 1-4 , an anti-clogging submersible pump, comprising a submersible pump body 1, a water inlet bin 2 is arranged in the middle of the submersible pump body 1, a water inlet port 3 is opened on the outer wall of the water inlet bin 2, a cleaning structure 11 is rotatably connected to the outer wall of the water inlet bin 2, mounting blocks 4 are arranged on both sides of the top of the submersible pump body 1, a guide wheel 5 is arranged inside the mounting block 4, support rods 13 are arranged on both sides of the top of the submersible pump body 1, and a fixing structure 12 is rotatably connected inside the support rod 13;

[0032] The fixed structure 12 includes a rotating shaft 1201, which is rotatably connected to the inside of the support rod 13, a flat spiral spring 1202 is arranged between the rotating shaft 1201 and the support rod 13, a mounting frame 1203 is arranged on the outer wall of the rotating shaft 1201, a fitting ring 1204 is arranged at one end of the mounting frame 1203, a fitting strip 1205 is arranged on the outer wall of the fitting ring 1204, a stretching rope 1206 is arranged inside the mounting frame 1203, and the outer wall of the stretching rope 1206 is fitted with the outer wall of the guide wheel 5.

[0033] Furthermore, a water outlet 6 is provided in the middle of the top of the submersible pump body 1, connecting chains 7 are provided on both sides of the top of the submersible pump body 1, and fixing rings 8 are provided on the tops of the two connecting chains 7. Rotating rods 9 are rotatably connected to both sides of the tops of the fixing rings 8, and one end of the rotating rod 9 is rotatably connected to a support block 10, which is fixedly connected to the wellhead of the deep well, thereby limiting the position of the submersible pump body 1 in the deep well and maintaining the depth of the submersible pump body 1.

[0034] Furthermore, the cleaning structure 11 includes a rotating ring 1101, which is rotatably connected to the top and bottom of the water inlet bin 2, and a cutting blade 1102 is arranged between the two rotating rings 1101. One side of the cutting blade 1102 is slidably connected to the outer wall of the water inlet bin 2, and the outer wall of the rotating ring 1101 is provided with rotating blades 1103. The number of the rotating blades 1103 is set to multiple, and the multiple rotating blades 1103 are arranged in a ring array on the outer wall of the rotating ring 1101. During the operation of the submersible pump body 1, the rotating blades 1103 are driven to rotate, and the rotating blades 1103 drive the rotating ring 1101 to rotate, so that the rotating ring 1101 drives the cutting blade 1102 to slide on the outer wall of the water inlet bin 2, so as to clean the impurities attached to the outer wall of the water inlet bin 2 and avoid blockage of the submersible pump body 1.

[0035] Furthermore, the fitting ring 1204 is arranged in an arc shape, and the fitting strip 1205 arranged on the outer wall of the fitting ring 1204 is made of rubber material. The fitting strip 1205 on the outer wall of the fitting ring 1204 fits with the inner wall of the deep well, and is used to fix the position of the submersible pump body 1, and pull the stretching rope 1206, so that the stretching rope 1206 drives the mounting frame 1203 to rotate, and the mounting frame 1203 squeezes the planar scroll spring 1202, and the fitting ring 1204 drives the fitting strip 1205 to separate from the well wall, so that the submersible pump body 1 can be taken out from the inside of the deep well.

[0036] In this embodiment, when the submersible pump body 1 needs to be placed in a deep well to extract liquid, the support block 10 is fitted with the wellhead of the deep well, and then the submersible pump body 1 is placed into the deep well through the connecting chain 7, so that the submersible pump body 1 enters the water, and then the stretch rope 1206 is loosened, the plane scroll spring 1202 is reset and drives the mounting frame 1203 to rotate, the mounting frame 1203 drives the fitting ring 1204 to rotate, and the fitting ring 1204 drives the fitting strip 1205 to fit with the inner wall of the deep well, and the maximum distance between the two fitting rings 1204 is less than the inner diameter of the deep well, such as Figure 1 As shown, the angle of the fixing structure 12 is the angle for fixing the submersible pump body 1, so that the fixing structure 12 can firmly fix the submersible pump body 1 inside the deep well. The heavier the submersible pump body 1 is, the more the fixing structures 12 on both sides of the top of the submersible pump body 1 can fit the inner wall of the deep well.

[0037] When the submersible pump body 1 extracts liquid, the liquid passes through the rotating blades 1103 and drives the rotating blades 1103 to rotate. The rotating blades 1103 drive the rotating ring 1101 to rotate, so that the rotating ring 1101 drives the cutting blade 1102 to rotate on the outer wall of the water inlet bin 2 to clean the impurities attached to the outer wall of the water inlet bin 2.

[0038] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
