Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 , Figure 2 , Figure 3 as well as Figure 4The utility model provides a technical solution: a high-lift submersible pump, comprising a pump body 1, a barrier component for filtering external impurities and a protective component for protecting the pump body 1, the barrier component comprising a first connecting plate 21 connected to one side of the pump body 1, a filter cover 22 arranged on one side of the first connecting plate 21, a transverse plate 23 connected to the inner wall of the filter cover 22, a protective cover 24 connected to one side of the transverse plate 23, a motor 25 arranged in the protective cover 24, a rotating shaft 26 connected to the output end of the motor 25, an extension frame 27 connected to both sides of the rotating shaft 26, two first extrusion grooves 28 opened in the extension frame 27, two second extrusion grooves 29 opened in the extension frame 27, and extrusion grooves 28 and 29 respectively arranged in the first extrusion groove 28 and the second extrusion groove 29.

The filter cover 22 can filter external impurities, protect the pump body 1, and improve the service life of the pump body 1. The motor 25 can drive the rotating shaft 26 to rotate, and then drive the extension frame 27 to rotate, and then drive the scraper 31 to rotate. The first spring 32 is initially in a compressed state, so that the scraper 31 can contact with the filter cover 22 after wear, and the scraper 31 can rotate to remove impurities. The impurities on the outside of the filter cover 22 are cleaned up and can pass through the filter cover 22 to ensure the filtering performance. The locking component includes a slot 51 opened on one side of the first connecting plate 21, a plug plate 52 connected to one side of the filter cover 22, sliding openings 53 respectively opened on both sides of the slot 51, locking grooves 54 respectively opened on both sides of the plug plate 52, a locking rod 55 connected to the sliding opening 53, a pull plate 56 connected to one end of the locking rod 55, and a third spring 57 sleeved on the outside of the locking rod 55, the two ends of the third spring 57 are respectively fixedly connected to the pull plate 56 and the first connecting plate 21, the locking rod 55 is plugged into the locking groove 54, and the locking rod 55 is slidably connected to the sliding opening 53. The locking rod 55 can be moved by pulling the pull plate 56, and the third spring 57 can be moved. The third spring 57 deforms synchronously, and the plug plate 52 on one side of the filter cover 22 can be inserted into the slot 51. The reaction force generated by the deformation of the third spring 57 can push the locking rod 55 to be inserted into the locking groove 54, so that the filter cover 22 can be connected and fixed to the pump body 1, which is convenient for protecting the pump body 1, and the filter cover 22 can be easily disassembled and replaced. A stop groove 61 is provided on one side of the extrusion rod 30, and a stop rod 62 is fixedly connected in the first extrusion groove 28 and the second extrusion groove 29. The stop rod 62 is slidably connected to the stop groove 61.

The second connecting plate 41 is located on the outside of the first connecting plate 21, and the contact ring 45 can contact the bottom surface. As the pump body 1 is pressed downward, the second spring 46 will be squeezed and deformed. The elasticity of the second spring 46 can be used to provide a certain degree of protection for the pump body 1, reduce the vibration of the pump body 1 when it falls, and increase the service life of the pump body 1. A friction block 441 is fixedly connected to one side of the protection rod 44, and the friction block 441 contacts the inner wall of the protection groove 43. The friction block 441 can move synchronously with the protection rod 44 to generate damping, thereby preventing the second spring 46 from repeatedly jumping after deformation, thereby ensuring the stability of the pump body 1. A protection pad 451 is provided on one side of the contact ring 45, and the protection pad 451 is adhered to the contact ring 45. The protection pad 451 can play a protective role, can protect the contact ring 45, and can increase its service life.

[0025] Working principle: During operation, pulling the pull plate 56 can drive the locking rod 55 to move, and at the same time, the movement of the pull plate 56 can cause the third spring 57 to deform, and then the plug plate 52 on one side of the filter cover 22 is inserted into the slot 51, and the pull plate 56 is released. The third spring 57 is reset to allow the locking rod 55 to be inserted into the locking slot 54, so that the filter cover 22 and the pump body 1 can be connected and fixed. When the pump body 1 is in use, the protective pad 451 can contact the bottom surface. Due to the gravity of the pump body 1, the pump body 1 can drive the second connecting plate 41 to move, and the second connecting plate 41 can drive the support rod 42 to move, thereby squeezing the second spring 46 to deform it, which can reduce the vibration of the pump body 1 and improve the stability of the pump body 1. The filter cover 22 can be used to remove external impurities. The filter is filtered to prevent impurities from entering the pump body 1, and then the motor 25 can be started. The motor 25 can drive the rotating shaft 26 to rotate, and the rotating shaft 26 can drive the extension frame 27 to rotate. The rotation of the extension frame 27 can rotate the scraper 31, and the scraper 31 can clean and dredge the impurities on the outside of the filter cover 22 to ensure the filtering stability of the filter cover 22. Since the first spring 32 is initially in a compressed state, after the scraper 31 is worn, the first spring 32 can push the scraper 31 to always contact with the filter cover 22, thereby ensuring the cleaning performance and preventing the cleaning performance from decreasing after the scraper 31 is not in contact with the filter cover 22. The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
