Description

Technical Field

[0001] The utility model relates to the technical field of water pumps, in particular to a pump body protection device. Background Art

[0002] A pump is a machine that transports or pressurizes fluids. It transfers the mechanical energy of the prime mover or other external energy to the liquid, increasing the liquid's energy. Pumps are primarily used to transport liquids such as water, oil, acid and alkali solutions, emulsions, suspensoids, and liquid metals. They can also transport liquid-gas mixtures and liquids containing suspended solids. Pumps are often used in conjunction with protective devices.

[0003] Prior art, such as the utility model patent with publication number CN218882594U, discloses a pump body protection device comprising a pump body and a protective mechanism mounted at the water inlet of the pump body. The protective mechanism comprises a protective filter screen, a waterproof housing, a waterproof motor, a drive shaft, a crossbeam, and a cleaning roller. The outer periphery of the protective filter screen is machined to have several groups of filter holes. The waterproof housing is fixed to the bottom of the protective filter screen. The waterproof motor is built into the waterproof housing, with its power output end passing through the bottom of the protective filter screen. The power output end of the waterproof motor is connected to the drive shaft. The crossbeams are divided into two groups and symmetrically mounted on either side of the drive shaft. The outer ends of the crossbeams are connected to the cleaning roller. The cleaning roller comprises a roller body and several groups of cleaning protrusions machined onto the surface of the roller body. The utility model improves the structure of the underwater pump body by installing a cleaning mechanism within the protective outer housing of the pump body. This mechanism can simultaneously clean the mesh of the protective outer housing while filtering water through the protective outer housing, thus preventing the possibility of mesh blockage.

[0004] At present, most pump body filters are prone to debris getting stuck in the holes of the filter screen. However, the existing cleaning method only cleans the protruding debris, but cannot deal with the debris stuck in the holes, resulting in continuous clogging of the filter screen. Over time, it is easy to cause a large number of holes in the filter screen to be clogged, affecting the normal use of the pump. This needs to be improved. Utility Model Content

Over time, a large number of holes on the filter screen are easily clogged, affecting the normal use of the pump, and a pump body protection device is proposed.

[0006] In order to achieve the above-mentioned object, the present invention adopts the following technical scheme: a pump body protection device, comprising a pump body, a handle fixedly connected to the upper surface of the pump body, a wire installed at the upper end of the pump body, a mounting bracket fixedly connected to the lower end of the pump body, a filter fixedly connected to the lower end of the filter fixedly connected to the base, a leg fixedly connected to the lower surface of the base, a cleaning device provided on one side of the filter, the cleaning device comprising a cleaning cover, the cleaning cover is located on one side of the filter, the upper and lower surfaces of the cleaning cover are fixedly connected to a slide, the two slides slide with the mounting bracket and the inner wall of the base respectively, a pumping pump fixedly connected to one side of the cleaning cover, the input end of the pump fixedly connected to a conduit, one end of the conduit is fixedly connected to the cleaning cover, a groove is provided on the side of the cleaning cover close to the filter, the conduit is connected to the groove, and an auxiliary component is provided on the surface of one of the slides. This scheme effectively cleans the clogged part in the filter, avoids the filter clogging affecting the normal use of the equipment, thereby improving the service life of the equipment, reducing the economic loss of the user, and facilitating the normal use of the equipment.

[0007] Preferably, the output end of the pump is fixedly connected to a nozzle, which is arranged in a horizontal direction. When the pump is turned on, the pump will suck the aquatic plants and objects blocked in the filter holes into the groove and discharge them through the conduit and nozzle.

[0008] Preferably, one side of the cleaning cover is fixedly connected to a connecting frame, and the side of the connecting frame away from the cleaning cover is fixedly connected to a scraper. When the equipment is in use, the pump body is placed in water, the pump body is used for a period of time, and the filter screen is removed. Then the drive motor is turned on, and the drive motor drives the guide wheel to rotate. Then the cleaning cover starts to rotate, and the scraper immediately moves along the surface of the filter screen, and the scraper cuts off the water plants or other objects blocking the filter screen holes.

[0009] Preferably, the cleaning cover is in an arc shape, and the cleaning cover fits the surface of the filter screen, so that the groove fits the holes on the filter screen, and the water plants and debris blocked in the holes are sucked out and discharged.

[0010] Preferably, the number of the scrapers is two, and the two scrapers are mirror-imaged with the cleaning cover as the axis of symmetry, so as to facilitate normal use of the equipment.

[0014] In the present invention, when the device is in use, the pump body is placed in water, the pump body is used for a period of time, the filter screen is filtered, and then the drive motor is turned on. The drive motor drives the guide wheel to rotate, and then the cleaning cover starts to rotate. The scraper then moves along the surface of the filter screen, and the scraper cuts off the aquatic plants or other objects blocking the filter screen holes. The pumping pump is turned on, and the aquatic plants and objects blocking the filter screen holes are sucked into the groove and discharged through the conduit and nozzle. This solution effectively cleans the blocked part of the filter screen, avoids the filter screen blockage affecting the normal use of the equipment, thereby increasing the service life of the equipment, reducing the economic loss of the user, and facilitating the normal use of the equipment.
