There is no need to build a special pump room to install the pump and machine, which can save a lot of land and infrastructure costs. When the submersible sewage pump works for a long time, heat energy will be generated inside, which needs to be discharged in time to increase the continuous use time of the equipment. Therefore, an automatic cooling device is needed for the submersible sewage pump.

[0003] After searching, for example, Chinese patent document CN216241359U discloses a submersible sewage pump cooling device, which connects the water inlet tank and the water storage tank at both ends of the cooling box, and uses a micro-impeller to connect the water outlet. A small amount of sewage is drawn from the relatively evenly mixed sewage at the water outlet into the cooling box, and then spirals around the shell for multiple turns along the route of the spiral plate and is discharged. During this period, the heat dissipation effect on the pump body is reduced, and then the discharged sewage enters the volute and is discharged under the action of the main impeller. However, there are still the following defects:

[0004] When the automatic cooling device for the submersible sewage pump is in use, even if there is a filter, the fine mud and sand impurities contained in the water will still enter the cooling box. After long-term use, they will adhere to the inner wall, resulting in a smaller water flow rate and a worse heat conduction and heat dissipation effect, making it inconvenient to clean the interior.

The top of the base 101 is fixedly connected, and the space between the outer wall 5 of the cooling pipe and the outer side of the submersible sewage pump body 1 can be divided by setting twelve groups of cooling pipe inner wall partitions 104, so that after water enters therein, the stroke becomes longer, and the submersible sewage pump body 1 can be better cooled, and the cooling pipe inner wall partitions 104 connected to the submersible sewage pump body 1 extend outward, increasing the contact area with the cooling water, thereby improving the cooling effect on the submersible sewage pump body 1, and a downwardly recessed card groove 102 is provided at the top of the base 101 near the outer wall 5 of the cooling pipe, and the card groove 102 is a circular ring structure, and a sealing ring 103 is inlaid inside the card groove 102, and an upper water hole 106 with a filter structure is provided on the base 101, and the liquid in the drain pipe 3 can enter between the outer wall 5 of the cooling pipe and the submersible sewage pump body 1 through the opened upper water hole 106, and then the submersible sewage pump body 1 is cooled.

[0025] A water inlet pipe 2 is arranged at the bottom of the base 101 away from the submersible sewage pump body 1, a drain pipe 3 is arranged on one side of the water inlet pipe 2, a cooling pipe outer wall 5 is arranged on the side of the submersible sewage pump body 1, and the cooling pipe outer wall 5 is arranged at the top of the base 101, a positioning ring 4 is arranged on the top of the cooling pipe outer wall 5, and the positioning ring 4 is plug-connected with the submersible sewage pump body 1, the bottom of the positioning ring 4 is fixedly connected with the cooling pipe outer wall 5, and twelve groups of cooling pipe outer wall partitions 401 are also arranged at the bottom of the positioning ring 4, and one group of cooling pipe outer wall partitions 401 is distributed between two groups of cooling pipe inner wall partitions 104, the length of the cooling pipe outer wall partition 401 is consistent with the length of the cooling pipe inner wall partition 104, and the cooling pipe outer wall partition 401 is close to the bottom of the base 101 and does not contact the base 101, and the cooling pipe outer wall partition 40 1 is fixedly connected with the outer wall 5 of the cooling pipe. The space between the outer wall 5 of the cooling pipe and the submersible sewage pump body 1 can be divided for the second time by setting the outer wall partition 401 of the cooling pipe. Cooperating with the inner wall partition 104 of the cooling pipe, the path through which the liquid flows can be changed into an S shape, thereby increasing the stroke of the liquid and cooling the submersible sewage pump body 1 better. Among the twelve groups of cooling pipe outer wall partitions 401 of the positioning ring 4, one group is a fixed partition 6 near the drain pipe 3. The fixed partition 6 is fixedly connected with the submersible sewage pump body 1, and the length of the fixed partition 6 is consistent with the length of the outer wall 5 of the cooling pipe. The fixed partition 6 can block the path of the water flow, so that the water flow entering between the outer wall 5 of the cooling pipe and the submersible sewage pump body 1 has a starting point and an end point, allowing the liquid to enter from the upper water hole 106 on one side of the fixed partition 6 and flow out from the drain hole 403 on the other side of the fixed partition 6.

The channel divided by the wall partition 401 and the cooling pipe inner wall partition 104 flows outside the submersible sewage pump body 1. The cooling pipe inner wall partition 104 contacting the submersible sewage pump body 1 will increase the heat dissipation area of ​​the cold water, and cool the submersible sewage pump body 1 faster and better. A drainage pump 404 is arranged inside the top positioning ring 4, which can quickly pump away the water of the submersible sewage pump body 1 and the cooling pipe outer wall 5 through the circulating water pipe 402 and the drainage hole 403 to ensure the cooling water circulation inside. The positioning ring 4 is obtained by the positioning plate 405 and the positioning bolt 406. To fix, after loosening the positioning bolts 406, the positioning ring 4 and the outer wall of the cooling pipe 5 can be pulled out upwards, thereby opening the internal space of the submersible sewage pump body 1 and the outer wall of the cooling pipe 5, making it convenient to clean the inner wall partition 104 of the cooling pipe and the outer wall partition 401 of the cooling pipe, avoiding the adhesion of impurities to the inner wall partition 104 of the cooling pipe and the outer wall partition 401 of the cooling pipe, resulting in a poor cooling effect, meeting different functional use requirements, and thus an automatic cooling device for a submersible sewage pump is completed.
