[0016] (1) By setting up an installation cover, a ventilated mesh, a fixing nut, a threaded shaft, a fan blade, a transmission block, and a drive plate, when the motor is running, the output shaft drives the fan blade to rotate through the external transmission block in conjunction with the drive plate. While the fan blade rotates, it accelerates the air circulation inside the motor body and exhausts the air from the ventilated mesh, thereby quickly dissipating the heat inside the motor body and reducing the temperature inside the motor body, so as to improve the stability of the motor in high temperature conditions and achieve effective heat dissipation and cooling.

[0017] (2) By setting up a mounting bracket, base plate, threaded column, support plate, support nut, fixing plate, positioning nut and groove, when installing, after connecting the output shaft to the equipment, the base plate can be pulled to adjust its height so that the base plate can fit against the mounting surface. Then, rotate the support nut to fit against the bottom end of the fixing plate and then rotate the positioning nut to fit against the top end of the fixing plate. Thus, the motor is supported and positioned as a whole by the fixing plate and mounting bracket. The support plate fits into the groove to ensure installation stability and realizes the ability to adjust the installation height according to the requirements.

[0018] (3) By setting up an installation cover, positioning slot, positioning cylinder, spring, fixed block and movable slot, after the motor has been running for a long time, multiple sets of springs can be pulled to drive the fixed block to get out of the positioning slot. Then the installation cover can be pulled to remove it from the outside of the positioning cylinder. Then the fixed nut can be rotated to remove the fan blade to facilitate the maintenance of the internal components of the motor body. After completion, the installation cover is put on the outside of the positioning cylinder so that the fixed block and the positioning slot can be engaged to position the installation cover, thus realizing convenient disassembly and assembly for internal maintenance.

[0025] Example: Please refer to Figure 1-4 A high-temperature resistant explosion-proof asynchronous motor includes a motor body 1, an output shaft 2 movably connected inside the motor body 1, a base plate 4 at the bottom of the motor body 1, the center line of the base plate 4 and the center line of the motor body 1 being on the same vertical plane, and a cooling structure for quickly dissipating heat from the motor being provided on one side of the motor body 1.

[0026] The cooling structure includes a mounting cover 10, a mounting cover 10 is movably connected to one side of the motor body 1, a breathable mesh 11 is embedded in one side of the mounting cover 10, a threaded shaft 13 is fixedly connected to one side of the output shaft 2, a fan blade 14 is movably connected to the outside of the threaded shaft 13, two sets of drive plates 21 are fixedly connected to both ends of the fan blade 14, a set of transmission blocks 20 are fixedly connected to the same side of both ends of the output shaft 2, and a fixing nut 12 is movably connected to the outside of the threaded shaft 13.

[0027] The transmission block 20 is movably connected to the drive plate 21, and the fan blade 14 is movably connected to the output shaft 2;

[0028] The fixing nut 12 is movably connected to the fan blade 14, and the center line of the threaded shaft 13 is on the same horizontal plane as the center line of the output shaft 2.

[0029] Specifically, if Figure 1 , Figure 2 and Figure 3 As shown, when the motor is running, the output shaft 2 drives the fan blade 14 to rotate through the external transmission block 20 and the drive plate 21. While the fan blade 14 rotates, it accelerates the air circulation inside the motor body 1 and exhausts the air through the ventilation mesh 11, thereby quickly dissipating the heat inside the motor body 1 and reducing the temperature inside the motor body 1. This improves the stability of the motor when it is running at high temperatures and achieves effective heat dissipation and cooling.

[0030] Mounting brackets 3 are fixedly connected to both sides of the bottom of the motor body 1. Fixing plates 8 are fixedly connected to both ends of the mounting brackets 3. A set of threaded columns 5 are fixedly connected to both sides of the top of the base plate 4. A positioning nut 9 is movably connected to the top of the fixing plate 8. A support nut 7 is movably connected to the bottom of the fixing plate 8. Grooves 22 are provided on both sides of the mounting brackets 3. Two sets of support plates 6 are fixedly connected to both sides of the top of the base plate 4.

[0031] The support nut 7 is threadedly connected to the threaded post 5, and the positioning nut 9 is threadedly connected to the threaded post 5.

[0032] The support plate 6 is movably connected to the groove 22, and the fixing pieces 8 at both ends of the mounting bracket 3 are symmetrically arranged;

[0033] Specifically, if Figure 1 and Figure 4 As shown, during installation, after connecting the output shaft 2 to the equipment, the height of the base plate 4 can be adjusted by pulling it so that the base plate 4 can fit against the mounting surface. Then, the support nut 7 is rotated to fit against the bottom end of the fixing plate 8, and then the positioning nut 9 is rotated to fit against the top end of the fixing plate 8. Thus, the motor is supported and positioned as a whole by the fixing plate 8 and the mounting bracket 3. The support plate 6 fits into the groove 22 to ensure installation stability, and the installation height can be adjusted according to the requirements.

[0034] A positioning cylinder 16 is fixedly connected to one side of the motor body 1. Four sets of positioning slots 15 are opened on the outside of the positioning cylinder 16. Four sets of movable slots 19 are opened on one side of the mounting cover 10. A spring piece 17 is fixedly connected to one side inside the movable slot 19. A fixing block 18 is fixedly connected to one end of the spring piece 17.

[0035] The fixing block 18 is movably connected to the positioning slot 15, and the positioning cylinder 16 is movably connected to the mounting cover 10;

[0036] Specifically, if Figure 1 and Figure 2 As shown, after the motor has been running for a long time, multiple sets of springs 17 can be pulled to move the fixing block 18 out of the positioning slot 15. Then, the mounting cover 10 can be pulled to remove it from the outside of the positioning cylinder 16. After that, the fixing nut 12 can be rotated to remove the fan blade 14 to facilitate the maintenance of the internal components of the motor body 1. After completion, the mounting cover 10 is put on the outside of the positioning cylinder 16 so that the fixing block 18 and the positioning slot 15 can be engaged to position the mounting cover 10, which realizes convenient disassembly and assembly for internal maintenance.

[0037] Working Principle: During installation, after connecting the output shaft 2 to the equipment, the height of the base plate 4 can be adjusted by pulling it, allowing it to fit against the mounting surface. Then, the support nut 7 is rotated to fit against the bottom of the fixing plate 8, and the positioning nut 9 is rotated to fit against the top of the fixing plate 8. Thus, the fixing plate 8 and the mounting bracket 3 provide overall support and positioning for the motor. The support plate 6 fits inside the groove 22, ensuring installation stability. When the motor is running, the output shaft 2 drives the fan blade 14 through the external transmission block 20 in conjunction with the drive plate 21. The rotation of the fan blade 14 accelerates the internal rotation of the motor body 1. The air circulation in the motor body 1 is improved, and the air is discharged through the ventilation mesh 11, thereby quickly dissipating the heat inside the motor body 1 and reducing the internal temperature of the motor body 1, so as to improve the stability of the motor when operating at high temperature. After the motor has been running for a long time, multiple sets of springs 17 can be pulled to drive the fixing block 18 out of the positioning slot 15. Then, the mounting cover 10 can be pulled to remove it from the outside of the positioning cylinder 16. Then, the fixing nut 12 can be rotated to remove the fan blade 14 for easy maintenance of the components inside the motor body 1. After completion, the mounting cover 10 is put on the outside of the positioning cylinder 16 so that the fixing block 18 engages with the positioning slot 15 to position the mounting cover 10.
