Description

Technical Field

[0001] The utility model relates to the technical field of water pumps, and particularly relates to a self-cleaning water pump. Background Technique

[0002] A water pump is a machine that transports liquids or increases the pressure of liquids. It transmits the mechanical energy of the prime mover or other external energy to the liquid, increasing the energy of the liquid. It is mainly used to transport liquids including water, oil, acid-base solutions, emulsions, suspension emulsions, and liquid metals, etc., and can also transport liquid-gas mixtures and liquids containing suspended solids.

[0003] The basic working principle of a water pump involves the rotation of an impeller or the reciprocating motion of a piston, thereby generating a pressure difference to suck in and discharge the liquid. The structure of a water pump usually includes components such as a pump casing, an impeller, a pump shaft, and a pump frame. The combination and design of these components determine the performance and application range of the water pump.

[0004] Water pumps perform excellently in a variety of application scenarios, capable of generating high pressure and large flow rates. Many water pumps have a self-priming function, eliminating the need for external water diversion, making them more convenient to use. They also have a stable structure, smooth operation, and multiple protection functions, reducing the likelihood of failures. These advantages enable water pumps to be widely used in multiple fields such as industry, agriculture, and households, such as farmland irrigation, industrial water supply, and household water use.

[0005] The liquid transported by a water pump usually contains some solid impurities. After the solid impurities are deposited in the water pump, the transportation efficiency of the water pump will be reduced. Water pumps in the prior art usually set up filters to intercept solid impurities, but this method of cleaning the water pump will still lead to a reduction in the transportation efficiency of the water pump after the filter is blocked or the impurities adsorbed by the filter are too much.

Detailed implementation manners

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0043] As Figures 1 to 4 shown, this embodiment proposes a self-cleaning water pump, including a water pump body 1, a pump casing 2, a cleaning casing 3, a filtering mechanism, a flow-blocking frame 4, a cleaning mechanism and a cleaning blade 5. The pump casing 2 is fixedly connected to the water pump body 1, and the cleaning casing 3 is fixedly connected between the pump casing 2 and the water pump body 1. The filtering mechanism is installed in the pump casing 2. There are multiple flow-blocking frames 4, and multiple flow-blocking frames 4 are fixedly connected in the pump casing 2. The cleaning mechanism is installed in the cleaning casing 3. There are multiple cleaning blades 5, and multiple cleaning blades 5 are located in the cleaning casing 3. The filtering mechanism enables the conveyed liquid to enter unidirectionally through the flow-blocking frame 4 and then flow out from the arc-shaped filter screen 6, playing a filtering role and not affecting the water conveyance efficiency of the water pump body 1 at the same time. After too much solid impurities accumulate in the flow-blocking frame 4, the cleaning mechanism can clear the solid impurities in the flow-blocking frame 4 into the cleaning casing 3, and there is no need to frequently disassemble and clean.

[0044] Among them, the filtering mechanism includes an arc-shaped filter screen 6 and a unidirectional water inlet assembly. There are multiple arc-shaped filter screens 6, and multiple arc-shaped filter screens 6 are respectively fixedly connected in multiple flow-blocking frames 4. The unidirectional water inlet assembly is installed on the flow-blocking frame 4. During operation, the liquid enters through the unidirectional water inlet assembly and flows out from inside the arc-shaped filter screen 6, effectively reducing the impurities in the transported liquid and preventing the impurities from depositing in the pump casing 2 and affecting the conveying efficiency of the water pump body 1.

[0045] Secondly, the cleaning mechanism includes a sealing plate 7, a connecting rod 9, a sealing ring 10 and an impurity removal component. The sealing plate 7 is fixedly connected to one end of the cleaning shell 3 away from the water pump body 1. A plurality of through holes 8 are provided on the sealing plate 7. There are a plurality of connecting rods 9, and the plurality of connecting rods 9 are fixedly connected to the motor output end of the water pump body 1. The sealing ring 10 is sealingly and slidably connected to the inner wall of the cleaning shell 3, and the sealing ring 10 is fixedly connected to the plurality of connecting rods 9. A plurality of cleaning blades 5 are fixedly connected to the sealing ring 10. The impurity removal component is installed in the cleaning shell 3. The cleaning mechanism removes impurities into the cleaning shell 3 through the impurity removal component. The sealing plate 7 and the sealing ring 10 can ensure the sealing of the pump body.

[0046] Thirdly, the unidirectional water inlet component includes a rotating shaft 11, a water blocking plate 12, a water blocking plate 13 and a limiting block 14. There are a plurality of rotating shafts 11, and two rotating shafts 11 are fixedly connected to each flow blocking frame 4. There are a plurality of water blocking plates 12, and one water blocking plate 12 is fixedly connected to one of the rotating shafts 11 on each flow blocking frame 4. There are a plurality of water blocking plates 13, and one water blocking plate 13 is fixedly connected to the other rotating shaft 11 on each flow blocking frame 4. There are a plurality of limiting blocks 14, and one limiting block 14 is fixedly connected to each water blocking plate 13. During operation, the liquid pushes open the water blocking plate 12 and the water blocking plate 13 and enters the cavity formed by the arc-shaped filter screen 6 and the inner wall of the pump shell 2. The limiting block 14 cooperates with the groove provided on the water blocking plate 12, so that the liquid cannot flow out of the water blocking plate inside, so it flows out through the arc-shaped filter screen 6 to achieve a filtering effect and reduce the solid impurities in the liquid.

[0047] Among them, the impurity removal component includes a scraping groove 15, a connecting block 16 and a sliding groove 17. There are a plurality of scraping grooves 15, and the plurality of scraping grooves 15 are slidably connected in the through holes 8. There are a plurality of connecting blocks 16, and the plurality of connecting blocks 16 are fixedly connected to the plurality of scraping grooves 15. There are a plurality of sliding grooves 17, and the plurality of sliding grooves 17 are opened on the cleaning shell 3. The plurality of connecting blocks 16 are slidably connected in the sliding grooves 17. The two ends of the scraping groove 15 are matched with the shape of the through hole 8, and both ends of the scraping groove 15 can seal the through hole 8 before and after pulling the connecting block 16.

[0048] Finally, the flow blocking frame 4 is in a herringbone shape, and a unidirectional water inlet component is installed between every two flow blocking frames 4.

[0049] In this embodiment, when the water pump is conveying liquid, the liquid enters the pump housing 2, and enters the cavity formed by the arc filter screen 6 and the inner wall of the pump housing 2 through the water blocking plate 1 12 and the water blocking plate 2 13. The limit plate prevents the water flow from flowing out through the water blocking plate 1 12 and the water blocking plate 2 13, and thus flows out through the arc filter screen 6. When a large amount of solid impurities are accumulated on the arc filter screen 6, the connecting block 16 is pulled, and the connecting block 16 drives the scraping groove 15 to move. The scraping groove 15 scrapes the impurities on the arc filter screen 6 into the cleaning shell 3. When the output end of the motor works, it drives the connecting rod 9 to rotate, and the rotating rod drives the sealing ring 10 to rotate, thereby driving the cleaning blade 5 to rotate to scrape the impurities on the scraping groove 15 and the cleaning shell 3 into the cleaning shell 3, and finally sends the scraping groove 15 back. The process is quick and effective.
