For example, Chinese Utility Model Patent No. CN202522082199.3 discloses a sewage pump comprising a pump body with a sealed cavity and a control box. The pump body has a through hole on the side wall of the sealed cavity, connecting the sealed cavity to the outside.

The check pipe is located at and connected to the through hole. The two check rings are located inside and connected to the check pipe. Each check ring has a mounting hole for the shaft to pass through. The collar is located on and connected to the shaft, situated between the two check rings. The spring is sleeved on the shaft, with its two ends abutting against the collar and the corresponding check ring, respectively.

[0004] In the existing technologies described above, the control box and the water pump body are designed as a single unit, which is inconvenient for later disassembly and maintenance. Therefore, further improvements to its structure are needed. Summary of the Invention

Detailed Implementation

[0026] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-8 As shown, an integrated direct-drive vertical axial flow pump includes a pump body 1 and an impeller assembly 2. A rotor shaft 3 and a stator assembly 4 are installed inside the pump body 1. A sealing cover 5 is installed at the end of the pump body 1, and a mesh cover 6 is installed at the end of the sealing cover 5. Several water inlets 7 are opened on the side wall of the mesh cover 6. A pump base 8 is installed at the end of the mesh cover 6, and a water outlet 9 is opened inside the pump base 8. An impeller assembly 2 connected to the end of the rotor shaft 3 is arranged inside the pump base 8. An installation cavity 10 for installing a heat dissipation box 11 is formed between the sealing cover 5 and the mesh cover 6. A control board 12 is arranged inside the heat dissipation box 11. Several heating elements 13 are arranged on the control board 12. The heating elements 13 are located on the side close to the mesh cover 6 and are in contact with the heat dissipation box 11 to conduct heat to the heat dissipation box 11.

[0028] This invention features an independent heat dissipation box design with the control board housed within it. The heat dissipation box is secured to the sealing cover 5 and the mesh cover 6 for easy installation and subsequent disassembly and maintenance. During operation, the heat generated by the control board 12 is transferred to the heat dissipation box 11, improving heat dissipation. Furthermore, when the impeller assembly 2 is in operation, water flows through the inlet 7, across the heat dissipation box 11, and out through the outlet 9, carrying away heat from the surface of the heat dissipation box 11 and further enhancing heat dissipation.

[0029] The heat dissipation box 11 has a first mounting through hole 14 in the middle for the connecting cylinder 16 to pass through, and the control board 12 has a second mounting through hole 15 in the middle. The control board 12 is equipped with a wireless control module, which can realize remote control of the pump body.

[0030] The sealing cover 5 has a connecting cylinder 16 formed in the middle, which is connected to the mesh cover 6. The connecting cylinder 16 has a through hole 17 for the rotor shaft to pass through.

[0031] The mounting through hole 14 and the mounting through hole 15 are respectively provided with mounting notches 18 on one side. Through the design of the mounting notches 18, the heat sink 11 can be quickly disassembled and assembled. The heat sink 11 can be disassembled and assembled from the side through the mounting notches 18, without having to disassemble the upper and lower parts in sequence, thus solving the problem of inconvenient disassembly and assembly of the existing structure.

[0032] The connecting cylinder 16 extends a limiting part 19 on one side, and the mesh cover 6 and the sealing cover 5 are designed as an integral part, which can reduce the number of parts to be assembled and make the assembly simpler.

[0033] A sealing seat 20 is formed in the middle of the mesh cover 6. A rotating bearing 21 is provided inside the sealing seat 20 to improve the support when the rotor shaft 3 rotates, making it more stable when rotating. The rotating bearing 21 is located on the outer periphery of the rotor shaft 3. A sealing element 22 is provided at the opening of the sealing seat 20 to prevent external liquid from entering the pump body.

[0034] One end of the rotor shaft 3 passes through a through hole and is connected to the impeller assembly 2. The other end of the rotor shaft 3 is equipped with a rotating bearing 23. The rotating bearing 23 is located on the inner wall of the pump body 1 to provide support for the rotor shaft 3 when it rotates, making it more stable when rotating.

[0035] The outer wall of the heat dissipation box 11 is formed with several heat dissipation ribs 24, which can increase the contact area and improve the heat dissipation effect.

[0036] The end face of the heat dissipation box 11 is formed with a number of heat dissipation blocks 25, which can increase the contact area and improve the heat dissipation effect.

[0037] The end face of the mesh cover 6 is provided with a number of heat dissipation holes 26 so that water flow can come into contact with the surface of the heat dissipation box 11 and the heat dissipation block 25 to improve the heat dissipation effect.
