[0002] A deep well pump is a water pump that integrates a motor and a pump. Its biggest feature is that it can be immersed in a groundwater well to pump and transport water. This design makes deep well pumps widely used in fields such as farmland irrigation and drainage, industrial and mining enterprises, urban water supply and drainage, and sewage treatment.
[0003] When the deep well pump is working, if it sucks in a large amount of mud and impurities, a large amount of dirt will accumulate inside the pump body. This dirt will seriously affect the water output efficiency of the deep well pump. Therefore, it is necessary to develop anti-fouling technology for the deep well pump. Summary of the invention
[0004] The utility model aims to provide an anti-fouling deep well pump which is easy to maintain in view of the above problems existing in the prior art.
[0005] The purpose of the utility model can be achieved through the following technical solutions: a kind of anti-fouling deep well pump, characterized in that it includes a water pump body, a supporting lug is provided on the water pump body, a plurality of water inlet holes are opened on the supporting lug, a rotating filter assembly is provided on the water inlet hole, a rotating shaft is provided on the filter assembly, and a plurality of pressure-bearing funnels are evenly distributed in an annular shape on the rotating shaft, a plurality of sleeves for fixing the rotating shaft are provided on the supporting lug, an arc-shaped filter screen is provided on the top of the water inlet hole, and a protective cover is provided on the top of the supporting lug.
[0006] In the above-mentioned anti-fouling deep well pump, brushes are arranged on the outside of the pressure-bearing funnel.
[0007] In the above-mentioned anti-fouling deep well pump, a limiting groove is arranged opposite to the protective cover and the supporting hanging ear, and a sealing gasket is arranged on the limiting groove.
[0008] In the above-mentioned anti-fouling deep well pump, a water inlet cavity is provided on the water pump body, a connecting lug is provided on the water inlet cavity, a plurality of fixing bolts are provided on the top of the protective cover, and the bottom of the fixing bolts is connected to the connecting lug.
[0009] In the above-mentioned anti-fouling deep well pump, a secondary filter screen is provided outside the water inlet cavity.
[0010] Compared with the prior art, the anti-fouling deep well pump reduces the amount of foreign matter that enters the water pump body by setting a filter at the water inlet hole, and sets a filter assembly at the water inlet hole to clean out the impurities intercepted by the filter, to prevent the filter from being blocked and causing water inlet difficulties, and to prevent the water pump from running idle. The secondary filter set on the water inlet cavity further prevents foreign matter from entering the water pump and prevents parts from getting stuck. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0016] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0017] like Figure 1 , 2 As shown in Figures 3 and 4, the anti-fouling deep well pump comprises a water pump body 4, a supporting lug 3 is provided on the water pump body 4, a plurality of water inlet holes 12 are opened on the supporting lug 3, a rotating filter assembly 2 is provided on the water inlet hole 12, a rotating shaft 16 is provided on the filter assembly, and a plurality of pressure funnels 14 are evenly distributed in an annular manner on the rotating shaft 16, a plurality of shaft sleeves 15 for fixing the rotating shaft 16 are provided on the supporting lug 3, an arc-shaped filter screen 5 is provided on the top of the water inlet hole 12, a protective cover 1 is provided on the top of the supporting lug 3, and the protective cover 1 and the supporting lug 3 form a closed structure so that water can only enter from the water inlet hole 12 at the bottom. When the water pump absorbs water, a water flow is formed in the water inlet hole 12, and the water flow pushes the pressure funnel 14 to rotate along the rotating shaft 16, and the impurities intercepted by the filter screen are entrained by the pressure funnel 14 and brought back to the water body, so as to prevent foreign matter from entering the water pump.
[0018] Preferably, a brush 13 is provided on the outside of the pressure funnel 14. The brush 13 rotates with the pressure funnel 14 to clean impurities adhering to the filter screen, thereby preventing the filter screen from being clogged and causing difficulty in absorbing water.
[0019] Preferably, a limiting groove 11 is provided opposite to the protective cover 1 and the supporting ear 3 , and a sealing gasket 7 is provided on the limiting groove 11 .
