[0002] In the prior art, water-cooled three-phase asynchronous motors are generally sealed, and the cooling water channel of the motor is sealed inside the motor casing, leaving only the water inlet and outlet for water circulation.

[0003] After long-term use of the motor, scale is easily generated inside the closed water channel of the existing technology, which blocks the water channel, causing obstruction of water circulation, affecting the water cooling effect, and further affecting the operation of the motor. Utility Model Content

[0004] The utility model provides a water-cooled three-phase asynchronous motor with easy-to-maintain water channels, which aims to overcome the above-mentioned shortcomings of the prior art, realize easy maintenance of the water channels of the water-cooling structure, and ensure the cooling effect.

[0005] The technical solution of this utility model is a water-cooled three-phase asynchronous motor with easily maintainable water channels. The motor structure includes a base, a sealing gasket, and a cover plate. A sandwich water channel is provided within the base. The top and two side surfaces of the base are provided with flat connection surfaces, each with an opening. Each opening corresponds to a corresponding connection surface connected to a cover plate. The top cover plate is provided with a water inlet and outlet. This allows for removable water channels for maintenance.

[0006] Preferably, a sealing gasket is provided between each of the cover plates and the corresponding connection surface, and the edges of the cover plates are evenly fixed by screws that pass through the cover plates, the sealing gaskets, and then connect to the corresponding screw holes on the connection surface, thereby improving the sealing effect of the water channel.

[0007] Preferably, sealant is applied between the sealing gasket and the connecting surface, and between the sealing gasket and the cover plate, to further improve the sealing effect.

[0008] The advantages of this utility model are: the structural design is simple and reasonable, the structure of the machine base is changed, and the water cooling machine base is detachable, which is convenient for assembly and disassembly. After disassembly, the water channel can be easily observed and the water channel can be easily cleaned in the event of blockage. It can effectively ensure the cooling effect of the motor, thereby ensuring the working effect of the motor. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The present invention will be further described in detail below with reference to the embodiments and specific implementation methods.

[0015] like Figure 1-4 A water-cooled three-phase asynchronous motor with easy-to-maintain water channels has a structure comprising a machine base 1, a sealing gasket 2 and a cover plate 3, wherein a sandwich water channel 11 is provided in the machine base 1, and a flat connecting surface 12 is provided on the top surface and both side surfaces of the machine base 1. The connecting surface 12 is provided with an open port 13, and a cover plate 3 is connected to the connecting surface corresponding to each open port 13. A sealing gasket 2 is provided between each cover plate 3 and the corresponding connecting surface 12, and the edges of the cover plate 3 are evenly fixed by screws 4 which pass through the cover plate 3, the sealing gasket 2 and then are connected to the corresponding screw holes on the connecting surface 12. A water inlet 31 and a water outlet 32 ​​are provided on the top cover plate 3.

[0016] During specific processing, three sides of the machine base 1 are opened to form an opening 13 , a plane is milled out of the machine base 1 blank to form a connecting surface 12 , and screw mounting holes are punched to facilitate the installation of the cover plate 3 .

[0017] The sealing gasket 2 and the cover plate 3 are installed on the machine base 1 to cover the interlayer water channel 11. Before installation, sealant is applied between the sealing gasket 2 and the connection surface 12 of the machine base 1 and between the sealing gasket 2 and the cover plate 3, and then fixed with screws 4 to ensure that the machine base 1 does not leak during water circulation.

[0018] When the cover plate 3 is sealed, the interlayer water channel 11 is closed-loop sealed, and water can circulate through the water inlet 31 and the water outlet 32 ​​to cool the motor.

[0019] When the motor needs maintenance after a long period of operation, or the water flow becomes smaller or in different situations, the cover plate 3 can be removed while the motor is being maintained to observe the condition of the interlayer water channel 11 and clean the interlayer water channel 11 .

[0020] The components described above are all prior art, and those skilled in the art can use any model and existing design that can achieve their corresponding functions.

[0021] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all fall within the scope of protection of the present invention.
