Description

Technical Field

[0001] This utility model belongs to the field of submersible electric pump technology, and specifically relates to a submersible electric pump. Background Technology

[0002] A submersible pump is a type of water pump in which both the pump body, impeller, and the motor driving the impeller are submerged in water. There are two types: one for deep wells and one for working surfaces. The motors used in submersible pumps include dry type (the motor is completely sealed), semi-dry type (the stator of the motor is sealed, while the rotor runs in the water), oil-filled type (the motor is filled with oil to prevent water from entering the windings), and wet type (the motor is filled with water, and both the stator and rotor run in the water).

[0003] In existing submersible pumps, the foreign object filter is either integrated with the pump or installed on it using bolts and flanges. This makes it extremely inconvenient to remove and clean the filter when it is damaged, affecting its usability. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the prior art by providing a submersible pump that facilitates the cleaning and replacement of the filter screen.

[0005] The objective of this utility model can be achieved through the following technical solution: A submersible electric pump, comprising a pump body and a pump cover, characterized in that a water pump motor is disposed within the pump body, a mounting cover is disposed at the upper end of the pump body, the pump cover is disposed on the mounting cover, the pump cover is provided with an inlet channel for water intake and an outlet channel for water output, a filter element for filtration is disposed on the pump cover and located at the inlet channel, a positioning protrusion for positioning the filter element is provided on the pump cover, the filter element is generally concave in structure, a groove for mounting the filter element is provided on the pump cover, and one end of the filter element extends into the groove, a positioning component for positioning the filter element is provided on the positioning protrusion, the positioning component consists of a positioning element and a return spring, a positioning hole for cooperating with the positioning element is provided on the filter element, and the filter element is fixed by cooperating with the positioning hole on the filter element.

[0006] In the aforementioned submersible pump, the inner wall of the positioning protrusion is in contact with the outer wall of the filter element. The positioning protrusion has an installation groove for installing the positioning component. One end of the positioning component extends out of the installation groove and is used to cooperate with the positioning hole. The other end of the positioning component extends out of the positioning protrusion and is connected to a pull rod. The positioning component is provided with a sliding part. One end of the return spring is connected to the sliding part, and the other end of the return spring is connected to the positioning protrusion.

[0007] In the aforementioned submersible electric pump, there are two positioning components, which are respectively located on both sides of the pump cover.

[0008] In the aforementioned submersible electric pump, the mounting cover is fixedly installed on the pump body by fixing bolts, and the pump cover is fixedly installed on the mounting cover by fixing bolts.

[0009] Compared with existing technologies, this submersible pump uses a positioning component that matches the positioning hole on the filter element to detachably fix the filter element at the water inlet channel, making it convenient for staff to maintain and replace the filter element.

[0014] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0015] like Figure 1 , Figure 2 , Figure 3 As shown, this submersible electric pump includes a pump body 1 and a pump cover 2. A water pump motor 3 is installed inside the pump body 1. A mounting cover 4 is provided at the upper end of the pump body 1. The pump cover 2 is mounted on the mounting cover 4. The pump cover 2 has an inlet channel 5 for water intake and an outlet channel 6 for water discharge. A filter element 7 for filtration is provided on the pump cover 2, located at the inlet channel 5. A positioning protrusion 8 for positioning the filter element 7 is provided on the pump cover 2. The filter element 7 has a concave overall structure. A groove for installing the filter element 7 is provided on the pump cover 2, with one end of the filter element 7 extending into the groove. A positioning component 9 for positioning the filter element 7 is provided on the positioning protrusion 8. The positioning component 9 consists of a positioning element 10 and a return spring 11. A positioning hole 12 is provided on the filter element 7 to cooperate with the positioning element 10. The filter element 7 is fixed by cooperating with the positioning hole 12 on the filter element 7.

[0016] To elaborate further, when the filter element 7 needs to be installed, first pull the positioning piece 10 so that it retracts into the mounting groove 13 of the positioning protrusion 8, and the return spring 11 is in a compressed state. Then, insert the filter element into the groove and release the positioning piece 10 at the same time. The return spring 11 rebounds, and one end of the positioning piece 10 is inserted into the positioning hole 12 of the filter element 7 to fix the filter element 7. When the filter element 7 needs to be disassembled, first pull the positioning piece 10 so that it retracts into the mounting groove 13 of the positioning protrusion 8, and the filter element 7 can be removed from the pump cover 2.

[0017] To elaborate further, the inner wall of the positioning protrusion 8 is in contact with the outer wall of the filter element 7. The positioning protrusion 8 has an installation groove 13 for the positioning component 9 to be installed. One end of the positioning component 10 extends out of the installation groove 13 and is used to cooperate with the positioning hole 12. The other end of the positioning component 10 extends out of the positioning protrusion 8 and is connected to a pull rod. The positioning component 10 is provided with a sliding part 14. One end of the return spring 11 is connected to the sliding part 14, and the other end of the return spring 11 is connected to the positioning protrusion 8.

[0018] To elaborate further, there are two positioning components 9, each located on one side of the pump cover 2. The two positioning components 9 simultaneously secure the left and right sides of the filter assembly, enhancing the stability of the filter element 7 during installation.

[0019] To elaborate further, the mounting cover 4 is fixedly installed on the pump body 1 by fixing bolts, and the pump cover 2 is fixedly installed on the mounting cover 4 by fixing bolts.
