Technical Field

[0001] The utility model relates to the technical field of water pump filtration, in particular to a water pump inlet filtering structure. Background Art

[0002] Water pumps are widely used equipment in industry, agriculture and daily life. Their main function is to transport water or other liquids from one place to another through mechanical energy. The water intake process of the water pump has a vital impact on its performance and life.

[0003] Most of the existing water pump inlet filter structures are not convenient for cleaning internal impurities, which cause the accumulation of internal impurities and shorten the service life. At the same time, some filter holes are easily clogged after long-term use, affecting the filtering effect and increasing the number and time of maintenance.

[0004] For this reason, we propose a water pump inlet filtering structure to solve the above problems. Utility Model Content

[0005] The purpose of the present utility model is to provide a water inlet filtering structure for a water pump, so as to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the present invention provides the following technical solutions: a water pump inlet filtering structure, comprising a water pump body,

[0007] A fixed tube is fixed to one side of the water pump body, and a fixed ring is fixedly sleeved on the surface of the fixed tube.

A first filter plate and a second filter plate are slidably provided on the inner wall of the movable tube, and a limit plate is fixed on the inner wall of the movable tube.

[0009] Preferably, the surfaces of the fixed tube and the connecting tube are fixedly sleeved with fixing rings, and slots are equidistantly provided around the surfaces of the fixing rings to improve the fixation of the two sides of the movable tube to the fixed tube and the connecting tube.

[0010] Preferably, the diameter of the movable tube is larger than the diameters of the fixed tube and the connecting tube, and the diameter of the fixed ring is consistent with that of the movable tube, thereby reducing the outflow waste of water.

[0011] Preferably, the arc plates are provided in multiple groups, and the multiple groups of arc plates are distributed on both sides of the surface of the movable tube, and at both ends of one side of the fixed tube and the connecting tube. Every two groups of arc plates are fixed by screws to facilitate installation and disassembly.

[0012] Preferably, the insert blocks are provided in multiple groups, and the multiple groups of insert blocks are fixed at equal distances on both sides of the movable tube, thereby reducing shaking and displacement of the fixed tube, the movable tube and the connecting tube during use and improving the stability of use.

[0013] Preferably, the springs are provided in multiple groups, and the multiple groups of springs are symmetrically fixed at both ends of both sides of the fixed column, wherein the first filter plate is fixed on the other side of two groups of springs, and the second filter plate is fixed on the other side of the other two groups of springs, so that the first filter plate and the second filter plate can be moved, thereby reducing the occurrence of impurities getting stuck.

[0014] Preferably, the surfaces of the first filter plate and the second filter plate are both provided with reserved holes, and the reserved holes are evenly distributed in multiple groups. The diameter of the reserved holes on the surface of the first filter plate is larger than the diameter of the reserved holes on the surface of the second filter plate, so that impurities of different sizes are filtered twice to improve the filtering effect.

[0015] Preferably, there are multiple groups of limit plates, two groups of limit plates are close to the first filter plate, and the other two groups of limit plates are close to the second filter plate, which limit the use position of the first filter plate and the second filter plate, so that the use position of impurities can be controlled, which is convenient for cleaning impurities.

[0016] The utility model provides a water pump inlet filtering structure, which has the following beneficial effects:

[0017] Through the coordinated use of movable tubes, fixed rings, curved plates, plugs and screws, the purpose of filtering impurities and cleaning can be achieved, which facilitates the regular disassembly and cleaning of the filter structure, reduces the accumulation of internal impurities, and keeps the filter plate unobstructed, so that the water pump can maintain a stable flow rate and head, ensuring the high efficiency of the system operation and extending the service life of the water pump and filter structure.

[0018] By cooperating with the fixing column, spring, first filter plate, second filter plate and limit plate, the purpose of reducing the blockage of the filter plate can be achieved, so that the water flow can pass smoothly and the impurities can be stably filtered, thereby reducing the jam of impurities in the filter holes, allowing clean water to flow through the water pump more smoothly, reducing the resistance of the water flow, improving the working efficiency of the water pump, and reducing the downtime caused by blockage, so that the water pump and filter device can work stably, thereby reducing the number and time of maintenance and improving the efficiency of use.

[0029] The water pump body 1 used in this application is a product that can be directly purchased on the market. Its principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described here in detail.

[0030] In the above embodiment, the whole is placed in a suitable position for use, and the multiple groups of plug blocks 7 on one side of the movable tube 3 are aligned with the slots 9 opened on the surface of the fixed ring 5. The movable tube 3 is pushed so that the multiple groups of plug blocks 7 pass through the slots 9. Then, one side of the movable tube 3 is close to the fixed ring 5. At the same time, the 96 on the surface of the movable tube 3 is aligned with the arc-shaped plate 6 on the surface of the fixed tube 2. Then, the multiple groups of arc-shaped plates 6 are fixed by screws 8. Finally, the other side of the movable tube 3 is fixed to the connecting tube 4 in the same way. When disassembly is required, the movable tube 3 can be taken out in the same reverse direction. The movable tube 3 can be replaced regularly.

[0031] Example 2

[0032] like Figure 4 and Figure 5As shown, based on the same concept as the above embodiment, this embodiment further proposes: a fixed column 10 is fixed to the inner wall of the movable tube 3, and springs 11 are fixed on both sides of the fixed column 10, a first filter plate 12 and a second filter plate 13 are slidably provided on the inner wall of the movable tube 3, and a limit plate 14 is fixed to the inner wall of the movable tube 3; a plurality of groups of springs 11 are provided, and the plurality of groups of springs 11 are symmetrically fixed at both ends on both sides of the fixed column 10, wherein the first filter plate 12 is fixed on the other side of two groups of springs 11, and the second filter plate 13 is fixed on the other side of the other two groups of springs 11; reserved holes are provided on the surfaces of the first filter plate 12 and the second filter plate 13, and the reserved holes are equidistantly distributed in a plurality of groups, the diameter of the reserved holes on the surface of the first filter plate 12 is larger than the diameter of the reserved holes on the surface of the second filter plate 13; a plurality of groups of limit plates 14 are provided, wherein two groups of limit plates 14 are close to the first filter plate 12, and the other two groups of limit plates 14 are close to the second filter plate 13.
