[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 The utility model provides an embodiment: a shielded internal circulation submersible sewage pump, comprising a centrifugal pump 1, which is the core component of the sewage pump, and the separation of water and impurities is achieved through the action of the centrifugal pump 1. The output end of the centrifugal pump 1 is fixedly connected with a detachable component for detaching the input pipe, so that when maintenance or replacement of parts is required, operation can be conveniently performed, which greatly improves maintenance efficiency. The other end of the detachable component is fixedly connected with an outlet pipe 5, and the other end of the outlet pipe 5 is fixedly connected with a filter cartridge 8, which filters out impurities in the water through the filter cartridge 8 to ensure the normal operation of the pump. The outer wall of the other end of the outlet pipe 5 is fixedly connected with a fixing ring 19, and the top of the fixing ring 19 is fixedly connected with a sealing ring 10, which is used to prevent water leakage. The top of the fixing ring 19 is detachably connected with a fixing ring 2 18, and the fixing ring 19 and the fixing ring 2 18 cooperate to realize the pipeline connection between the pump and the water-using equipment. The inner wall of the second fixing ring 18 is fixedly connected with a discharge pipe 19, and the inner wall of the discharge pipe 19 is fixedly connected with a filter plate 20. The filter plate 20 cooperates with the filter cartridge 8 to realize double-layer filtration to further remove impurities in the water.

[0033] The bottom of the fixing ring 1 9 and the top of the fixing ring 2 18 are detachably connected to a plurality of clamping plates 11. The clamping between the clamping plates 11 enables convenient disassembly between the fixing ring 1 9 and the fixing ring 2 18. The two clamping plates 11 are fixedly connected to the adjacent sides with a spring 2 28, and the two clamping plates 11 are fixedly connected to the distant sides with a spring 13. The other ends of the two springs 13 are fixedly connected to the upper and lower inner walls of the fixing plate 12, respectively. The springs 13 and 28 are used to increase the clamping force of the clamping plates 11, thereby making the connection between the fixing ring 1 9 and the fixing ring 2 18 more stable. The other ends of the two clamping plates 11 are slidably connected to the fixing plate 12, which provides a sliding path for the sliding of the clamping plates 11. The fixing plate 12 is internally rotatably connected to a rotating shaft 14, and one end of the rotating shaft 14 is fixedly connected to a rubber sleeve 15, which is convenient for staff to rotate. The other end of the rotating shaft 14 is fixedly connected to a rotating plate 16. Rotating the rubber sleeve 15 drives the rotating shaft 14, which in turn drives the transmission plate. Rotating plate 16 is rotatably connected to drive shafts 17 at each end. The other ends of the two drive shafts 17 are rotatably connected to the outer walls of the two clamping plates 11. Rotation of the rotating plate 16 drives the drive shafts 17 as well. Since the movement direction of the clamping plates 11 is fixed, the movement of the drive shafts 17 drives the clamping plates 11 toward each other. A heat sink assembly is fixedly connected to the outer wall of the pump housing 2 to dissipate heat generated during operation of the sewage pump.

[0034] The detachable component includes two connecting plates 6, the inner wall of one connecting plate 6 is fixedly connected to the output end of the centrifugal pump 1, and the inner wall of the other connecting plate 6 is fixedly connected to the outer wall of one end of the water outlet pipe 5. The internal threads of the two connecting plates 6 are connected with multiple screws 7. The connection between the centrifugal pump 1 and the water outlet pipe 5 is realized through the connection between the two connecting plates 6, and the connecting plates 6 are tightly fixed by the screws 7.

[0035] The top of the centrifugal pump 1 is fixedly connected to a pump casing 2, which is used to protect the internal working components that drive the centrifugal pump 1. The top of the pump casing 2 is detachably connected to a top cover 3, and the top of the top cover 3 is fixedly connected to a handle 4. The top cover 3 can be removed to inspect the working components inside the sewage pump.

[0036] Reference Figures 1 to 2The heat dissipation assembly includes a heat dissipation shell 27, which is used to protect internal components and provide sufficient space for heat dissipation. The inner wall of the heat dissipation shell 27 is fixedly connected to the outer wall of the pump housing 2, and a plurality of heat dissipation fins 26 are fixedly connected to the top of the centrifugal pump 1. The heat dissipation fins 26 improve the heat exchange efficiency by increasing the surface area and help dissipate the heat generated inside the pump. The heat dissipation fins 26 are usually made of materials with good thermal conductivity, such as aluminum alloy, to optimize the heat dissipation effect. The interior of the heat dissipation shell 27 is fixedly connected to a return water pipe 21, and the interior of the heat dissipation shell 27 is fixedly connected to a water inlet pipe 22. The return water pipe 21 and the water inlet pipe 22 are responsible for transporting the coolant to the heat dissipation assembly and circulating it therein to absorb and transfer heat. The other end of the return water pipe 21 is fixedly connected to a cooling box 23, which is a closed space for storing coolant. The other end of the water inlet pipe 22 is fixedly connected to the inside of the cooling box 23. A partition 24 is fixedly attached to the inner wall of cooling box 23. This partition divides cooling box 23 into two sections: one for storing heated coolant and the other for storing cooler coolant. This prevents direct mixing of hot and cold liquids, improving cooling efficiency. A water pump 25 is fixedly attached to the bottom inner wall of cooling box 23. The output of water pump 25 is located above partition 24. Water pump 25 draws coolant from cooling box 23 and delivers it to the heat dissipation assembly through water inlet pipe 22 for circulation.

[0037] Working principle: When in use, the sewage is sucked in for centrifugal separation through the action of the centrifugal pump 1, and the separated water enters the outlet pipe 5, and passes through the filter cartridge 8 and the filter plate 20 in turn into the discharge pipe 19, thereby entering the water equipment. When the filter plate 20 and the filter cartridge 8 need to be cleaned, the rubber sleeve 15 can be rotated to drive the rotating shaft 14 to rotate, and the rotation of the rotating shaft 14 drives the rotating plate 16 to rotate. The rotation of the rotating plate 16 drives the transmission shaft 17 to rotate and the transmission action of the transmission shaft 17 drives the two clamping plates 11 to move toward each other, thereby realizing the unlocking between the fixing ring 1 9 and the fixing ring 2 18, and then the filter cartridge 8 and the filter plate 20 can be disassembled for cleaning and dredging.

[0038] When the centrifugal pump 1 is working, the water pump 25 is turned on. The water pump 25 operates to transport the cooling liquid in the cooling box 23 to the inside of the heat dissipation shell 27 through the water inlet pipe 22, and absorbs the heat of the working components inside the pump shell 2 through the heat dissipation fins 26, thereby achieving the purpose of cooling the working components. The cooling liquid that has undergone heat exchange flows back to the bottom of the cooling box 23 through the return pipe 21 for further cooling, and liquid circulation is achieved through the water pump 25.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
