Description

Technical Field

[0001] The present invention relates to the technical field of permanent magnet motors, and in particular to a water channel structure of a low-speed, high-torque permanent magnet motor. Background Art

[0002] With the development of permanent magnet motors, low-speed, high-torque permanent magnet motors have gradually been used in various industries such as coal, cement, and logistics. However, the heat dissipation problem of high-power density motors has always plagued major manufacturers and researchers. In production, motor water channel structures are usually set up to cool low-speed, high-torque permanent magnet motors.

[0003] Although the existing low-speed, high-torque permanent magnet motor water channel structure can cool the motor body, it has some defects during use. For example, when the existing water channel structure is installed and used, when the cables of the permanent magnet motor body are passed through the water channel structure, the cables will be entangled with each other, which is inconvenient for personnel to operate during subsequent maintenance of the corresponding cables. In addition, after a certain number of years of use, the existing water channel structure will rust inside and produce rust residue, which will be mixed in the coolant and affect the cooling effect of the coolant on the motor body. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and propose a low-speed, high-torque permanent magnet motor water channel structure.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0022] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0023] Reference Figures 1-6 The water channel structure of the low-speed, high-torque permanent magnet motor includes a base inner cylinder 1, and a base outer cylinder 2 is fixedly sleeved on the outside of the base inner cylinder 1. Cooling liquid flows between the base inner cylinder 1 and the base outer cylinder 2 to cool the low-speed, high-torque permanent magnet motor and prevent the low-speed, high-torque permanent magnet motor from overheating during long-term operation, thereby affecting its working effect and service life.

[0024] Two wire outlets 3 are provided on the inner tube 1 of the machine base, and each wire outlet 3 passes through the outer tube 2 of the machine base. A flip plate 4 is rotatably provided in the wire outlet 3, and a plurality of splitting rods 5 are movably provided on the inner side wall of the flip plate 4. Two sliding grooves 6 are symmetrically provided on the inner side wall of the flip plate 4. A sliding block is fixed at both ends of each splitting rod 5, and the sliding block is damped in connection with the sliding groove 6. When in use, the flip plate 4 is flipped open, and then all the splitting rods 5 are moved upward, and then each cable to be threaded is passed through the flip plate 4 in turn, and a splitting rod 5 is pulled downward when a cable is passed through, and each cable is passed through the flip plate 4 in sequence, so that the cables are arranged more orderly and the cables are prevented from being entangled with each other. When a faulty cable needs to be repaired later, it can be found quickly, which is convenient for personnel to operate and improves work efficiency.

[0025] A connecting plate 7 is fixed to one side of each flip plate 4, and rotating columns 8 are fixed to both ends of the connecting plate 7. A rotating groove for cooperating with the connecting plate 7 is opened on the side wall of the outlet 3. The rotating column 8 is rotatably connected to the rotating groove, so that the connecting plate 7 can rotate on the rotating groove, causing the flip plate 4 to complete the opening and closing action on the outlet 3, cooperating with the operator to thread the wire.

[0026] A plurality of elastic friction balls 9 are fixed to one side of each flip plate 4 away from the connecting plate 7, and a friction groove for cooperating with the elastic friction ball 9 is provided on the side wall of the wire outlet 3. A buckle groove 10 is provided on the upper end surface of each flip plate 4. When the flip plate 4 is in a closed state, the flip plate 4 is located in the wire outlet 3, and the elastic friction balls 9 on the flip plate 4 open and close in the friction groove, limiting and fixing the flip plate 4 to prevent the flip plate 4 from flipping open during use and affecting the use effect. When threading work is required, the operator only needs to pull the buckle groove 10 outward to flip open the flip plate 4, which is easy to use.

[0027] A first fixing ring 11 and a second fixing ring 12 are fixed to both ends of the base inner tube 1 respectively, and a third fixing ring 13 is fixed to the outer wall of the base inner tube 1, and multiple water retaining rings 14 are fixed between the second fixing ring 12 and the third fixing ring 13. The third fixing ring 13 is located between the base inner tube 1 and the base outer tube 2. The cooling liquid circulates between the second fixing ring 12 and the third fixing ring 13 to cool the low-speed and high-torque permanent magnet motor. In addition, by setting up multiple water retaining rings 14, the flow time of the cooling liquid between the second fixing ring 12 and the third fixing ring 13 is extended, so that the cooling liquid can better take away the heat generated by the low-speed and high-torque permanent magnet motor during operation, thereby improving the cooling efficiency of the low-speed and high-torque permanent magnet motor.

[0028] A water inlet 15 and a water outlet are provided on the outer wall of the machine base outer cylinder 2, and the water inlet 15 and the water outlet are both threadedly connected with a mounting ring 16. A filter sleeve 17 is fixed to the bottom of the mounting ring 16, and a filter baffle 18 is fixed to the inner bottom of the filter sleeve 17. A filter adsorption layer 19 is placed in the filter sleeve 17. Since the filter sleeve 17 is fixed to the bottom of the mounting ring 16, when the mounting ring 16 is installed to the corresponding water inlet 15 and water outlet, the filter sleeve 17 is now between the machine base inner cylinder 1 and the machine base outer cylinder 2. Since a filter adsorption layer 19 is placed in the filter sleeve 17, when the coolant flows between the machine base inner cylinder 1 and the machine base outer cylinder 2, the coolant will pass through the filter adsorption layer 19, and the provided filter adsorption layer 19 will adsorb impurities such as rust residue mixed in the coolant, thereby preventing impurities such as rust residue from mixing in the coolant and reducing the use effect of the coolant.

[0029] A threaded ring 20 is provided on the fixed sleeve on the outer wall of the mounting ring 16, and a threaded groove is provided on the inner wall of the mounting ring 16. The mounting ring 16 is installed and fixed to the corresponding water inlet 15 and water outlet through the provided threaded ring 20. The connecting hose is connected to the corresponding mounting ring 16 through the provided threaded groove. The connecting hose is connected to the water tank so that the coolant can circulate and cool the low-speed, high-torque permanent magnet motor. After the filter adsorption layer 19 has been used for a certain period of time, the mounting ring 16 and the filter sleeve 17 can be rotated to remove the corresponding filter adsorption layer 19, thereby replacing the corresponding filter adsorption layer 19.

[0030] When the cable is threaded, the operator only needs to pull the buckle groove 10 outwards to flip open the flip plate 4, which is convenient to use. The flowing coolant cools down the low-speed, high-torque permanent magnet motor to prevent the low-speed, high-torque permanent magnet motor from overheating when working for a long time, affecting its working effect and service life. By setting up multiple water retaining bars 14, the flow time of the cooling liquid between the second fixing ring 12 and the third fixing ring 13 is extended, so that the cooling liquid can better take away the heat generated when the low-speed, high-torque permanent magnet motor is working, thereby improving the cooling efficiency of the low-speed, high-torque permanent magnet motor. When the coolant flows between the second fixing ring 12 and the third fixing ring 13, the coolant will pass through the filter adsorption layer 19, and the filter adsorption layer 19 provided will absorb impurities such as rust residue mixed in the coolant, thereby avoiding rust residue and other impurities from mixing in the coolant, reducing the use effect of the coolant. After the filter adsorption layer 19 has been used for a certain period of time, the mounting ring 16 and the filter sleeve 17 can be rotated to remove the corresponding filter adsorption layer 19, thereby replacing the corresponding filter adsorption layer 19.

Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, make some changes or modifications to equivalent embodiments using the technical contents disclosed above.
