In manufacturing, such as automobile production lines and machine tool processing; in the energy industry, such as water pumps and fans in power plants; and in the transportation sector, such as drive motors for electric vehicles, motors play a crucial role. However, motors face various fault risks during operation, such as overload, short circuit, underload, phase loss, and grounding. If these faults are not handled in time, they may damage the motor, thereby affecting the normal operation of the entire production process or equipment.

[0003] With the rapid development of electronic technology, various high-performance electronic components such as microprocessors, integrated circuits, and high-precision sensors are constantly emerging. These components provide the technological foundation for the intelligence and high precision of motor protectors. For example, microprocessors can realize real-time monitoring of motor operating parameters and complex logical judgments, enabling more accurate identification of the type and severity of motor faults.

[0004] Most existing motor protectors are installed in relatively small enclosures. While the small enclosure can protect the motor protector, the small environment leads to low light inside the enclosure. The small environment also makes the installation process more difficult and complicated. Furthermore, many common tools are limited by the space, ultimately resulting in low installation efficiency and a complicated process. Utility Model Content

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] The present invention will be further described below with reference to the embodiments.

[0030] Example 1:

[0031] Reference Figure 1-4 This is the first embodiment of the present utility model. A motor protector with an adjustable outer shell includes: a motor protector body 1 and a circular loading plate 2. The circular loading plate 2 is arranged directly below the motor protector body 1. A docking plate is also arranged on the lower surface of the motor protector body 1, and a docking hole is also opened through the vertical surface of the docking plate. A rigid suction cup 3 is arranged at the lower end of the circular loading plate 2. An L-shaped mounting plate 4 is fixedly connected to the arc surface of the circular loading plate 2. A miniature rotary vane vacuum pump 5 is also arranged on the upper surface of the L-shaped mounting plate 4. An arc-shaped connecting pipe 6 is also arranged on the miniature rotary vane vacuum pump 5. The arc-shaped connecting pipe 6 is connected through the rigid suction cup 3 at the end away from the miniature rotary vane vacuum pump 5. A U-shaped mounting frame 7 is also arranged on the upper surface of the circular loading plate 2. Mounting holes are opened through the vertical surface of the U-shaped mounting frame 7. A pair of circular limiting rods 8 are fixedly connected to the inner ring of the U-shaped mounting frame 7.

[0032] When the rigid suction cup 3 is pressed onto the surface of an object, the miniature rotary vane vacuum pump 5 will extract the air inside the suction cup, reducing the air pressure inside the suction cup and completely expelling the air from the suction cup, thus creating a near-vacuum state inside the suction cup.

[0033] Rectangular mounting strips 9 are provided on the vertical surfaces of both sides of the U-shaped mounting frame 7, and a mating hole is provided through the upper surface of the pair of rectangular mounting strips 9. An exhaust pipe 10 is provided through the arc surface of the rigid suction cup 3, and a temporary sealing cover 11 is rotatably connected to the upper section of the exhaust pipe 10. A pair of rectangular moving grooves 12 are provided on the horizontal surface of the circular loading tray 2, and a cylindrical guide rod 13 is provided inside the rectangular moving grooves 12.

[0034] T-shaped moving blocks 14 are provided inside the rectangular moving groove 12, and cylindrical guide rods 13 pass through the T-shaped moving blocks 14. Memory springs 15 are provided on the vertical surfaces of the T-shaped moving blocks 14 near the U-shaped mounting frame 7. One end of the memory spring 15 is connected to the T-shaped moving block 14, and the other end of the memory spring 15 is connected to the short vertical surface of the rectangular moving groove 12.

[0035] Each T-shaped moving block 14 has an L-shaped positioning rod 16 on its upper surface. Each pair of T-shaped moving blocks 14 is fixedly connected to the same arc-shaped pull rod 17. The upper surface of the temporary sealing cover 11 has a connecting port 18. The inner ring of the temporary sealing cover 11 also has an arc-shaped block 19, and the arc surface of the arc-shaped block 19 is also provided with a ball bearing. The cross-section of the exhaust pipe 10 is also provided with a stop block 20, and the stop block 20 is provided with an air inlet. The arc surface of the exhaust pipe 10 is provided with a rotating groove 21.

[0036] When using it, first hold the arc-shaped pull rod 17 with your hand, because both T-shaped moving blocks 14 are fixedly connected to the same arc-shaped pull rod 17, and each T-shaped moving block 14 has an L-shaped positioning rod 16 on its upper surface. Then pick up the motor protector body 1, because the lower surface of the motor protector body 1 is also provided with a docking plate, and the vertical surface of the docking plate is also provided with a docking hole, so you can put it down directly. After confirming that the motor protector body 1 is in place, you can release your hand directly, because each T-shaped moving block 14 is provided with a memory spring 15 near the vertical surface of the U-shaped mounting frame 7, and one end of the memory spring 15 is connected to the T-shaped moving block 14, and the other end of the memory spring 15 is connected to the short vertical surface of the rectangular moving groove 12. When the memory spring 15 has no resistance, the T-shaped moving block 14 will be pulled back, so that the pair of L-shaped positioning rods 16 can pass through the U-shaped mounting frame and the docking plate.

[0037] After installation, place the rigid suction cup 3 in the desired location. Note: Before installation, check for any leaks inside the cabinet. After checking, start the miniature rotary vane vacuum pump 5. When the rigid suction cup 3 is pressed onto the surface of the object, the miniature rotary vane vacuum pump 5 will extract the air from inside the suction cup, reducing the air pressure inside the suction cup and completely expelling the air. This will create a near-vacuum state inside the suction cup, which will eventually adhere to the object.

[0038] Example 2:

[0039] Reference Figure 1 and 5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: an air vent 22 is provided on the upper surface of the motor protector body 1, and a filter screen is also provided on the vertical surface inside the air vent 22. A pair of fixing blocks are also provided on the upper surface of the motor protector body 1, and a cylindrical slide rod 23 is provided through the vertical surface of the fixing block. A mounting plate is slidably connected to the rod of the cylindrical slide rod 23, and a pair of mounting plates are connected to the same moving plate 24.

[0040] During use, if the temperature inside the cabinet is too high, a pair of fixing blocks are installed on the upper surface of the motor protector body 1, and a cylindrical slide rod 23 is installed through the vertical surface of the fixing blocks. The mounting plate is slidably connected to the rod of the cylindrical slide rod 23, and a pair of mounting plates are connected to the same moving plate 24. Then, the operator can directly move the moving plate 24 to increase the area of ​​the air vent 22, thereby improving the air intake effect.

[0041] The remaining structure is the same as that in Example 1.

[0042] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
