Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of water pump, and relates to a deep well pump, in particular to a pollution-preventing deep well pump. BACKGROUND

[0002] The deep well pump is a high-efficiency water pumping device specially used for extracting water from a deep well or a groundwater source, is usually composed of multiple-stage impellers in series, and is driven by a motor to vertically lift water to the ground. The deep well pump is characterized by high lift (up to hundreds of meters) and compact structure, is suitable for an environment with narrow well diameter, and adopts a corrosion-resistant material (such as stainless steel) for the pump body to adapt to the groundwater working condition.

[0003] In order to prevent large-particle silt foreign matters from entering the water pump, a filtering water net is usually arranged on the deep well pump to intercept foreign matters. The conventional filtering water net is in an always-on state, and foreign matters in water will adhere to the mesh holes of the filtering water net, resulting in reduced water inlet efficiency, and thus the user needs to frequently take out the deep well pump and clean the deep well pump, increasing the use cost. Therefore, the anti-foreign-matter-enterring needs to be developed. SUMMARY

[0004] The utility model discloses to aim at above -mentioned problem in prior art, provide a kind of using simple and convenient, anti-clogging pollution-preventing deep well pump.

[0005] The utility model discloses a kind of pollution-preventing deep well pumps, it is characterized in that, including water pump main body, the water pump main body is equipped with impeller assembly and motor assembly, the water pump main body is equipped with water inlet section, the water inlet section is equipped with several connecting plates connecting impeller assembly and motor assembly, it is equipped with flexible filter screen between the connecting plate, the flexible filter screen is equipped with several expansion joints, it is equipped with connecting main shaft in the water inlet section, the connecting main shaft is equipped with several impeller spoiler, it is equipped with magnetic strip at the end of the impeller spoiler, the flexible filter screen is also equipped with several magnet A, the magnetic strip and magnet A magnetic pole are same and set to opposite.

[0006] In the above-mentioned pollution-preventing deep well pump, the connecting plate is equipped with several magnet B, the magnet B and the magnetic pole of magnetic strip are set to opposite.

[0007] In the above-mentioned pollution-preventing deep well pump, the flexible filter screen both ends are equipped with clamping block, the clamping block is equipped with several clamping barbs.

[0008] Compared with existing technologies, this anti-fouling deep well pump is equipped with a flexible filter screen on the pump body. The flexible filter screen protrudes and deforms by the rotation drive magnetic strip connected to the main shaft, thereby realizing the automatic opening of the filter screen. When closing, magnet B attracts the impeller baffle plate to make the magnetic strip face the connecting plate. The flexible filter screen retracts, causing the filter holes to shrink back and become expansion joints, preventing foreign objects in the water from depositing and sticking to the filter holes, which would lead to a reduction in the water intake.

[0014] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0015] like Figure 1 , 2 As shown in Figures 3 and 4, this anti-fouling deep well pump includes a pump body 5, an impeller assembly 1 and a motor assembly 6 on the pump body 5, an inlet section 4 on the pump body 5, and several connecting plates 2 connecting the impeller assembly 1 and the motor assembly 6 on the inlet section 4. Flexible filter screens 7 are provided between the connecting plates 2, and several expansion joints 3 are provided on the flexible filter screens 7. A connecting main shaft 9 is located inside the inlet section 4, and several impeller baffles 8 are provided on the connecting main shaft 9. Each of the 8 ends is equipped with a magnetic strip 11, and the flexible filter screen 7 is also equipped with several magnets A13. The magnetic poles of the magnetic strip 11 and the magnets A13 are arranged in the same direction. When the water pump starts, the motor rotates and drives the connecting main shaft 9 to rotate. The magnetic strip 11 at the end of the impeller baffle 8 rotates around the connecting main shaft 9. The magnetic poles of the magnets A13 are opposite, and the magnetic strip 11 repels the flexible filter screen 7 outward, causing the center of the filter screen to bulge and deform. The expansion joint 3 opens when deformed to form a filter hole 12. The flexible filter screen 7 is made of silicone material.

[0016] Preferably, the connecting plate 2 is provided with a plurality of magnets B10, the magnets B10 are arranged opposite to the magnetic strips 11 in terms of magnetic pole, after the water pump is closed, the motor continues to rotate under the action of inertia until it stops due to friction, the magnets B10 on the connecting plate 2 attract the magnetic strips 11 to make the impeller spoiler 8 face the connecting plate 2, and the flexible filter screen 7 is retracted when not repelled by the magnets to restore the filter holes 12 to the expansion joints 3.

[0017] Preferably, the flexible filter screen 7 is provided with clamping blocks 14 at both ends, the clamping blocks 14 are provided with a plurality of clamping barbs 15, the clamping barbs 15 prevent the flexible filter screen 7 from deforming and falling off.
