Description

Technical Field

[0001] This utility model relates to the field of motor heat dissipation technology, and in particular to a detachable, high-efficiency, and energy-saving motor heat dissipation device. Background Technology

[0002] Motor cooling devices are crucial for heat dissipation during motor operation. They can dissipate the heat generated by the motor, achieve continuous cooling, stabilize the motor's operating temperature, and improve working efficiency. They are widely used in industrial motors, automated equipment, and power equipment. However, most existing cooling devices are integrated fixed structures, which are prone to uneven gaps between cooling components. They also require additional power and have drawbacks such as poor energy-saving effect and low overall heat dissipation efficiency.

[0003] A search revealed Chinese Patent Publication No. CN217956849U, which discloses an auxiliary heat dissipation device for a motor, relating to the field of motor technology. The device includes a base with a filter screen, a support fixedly connected to the base, a through slot on the support, a motor mounted on the support, and a housing rotatably connected to the motor's output end. The housing contacts the base and is equipped with a dustproof mesh. A heat dissipation mechanism is provided on the motor, and a mounting mechanism is provided on the base. This invention utilizes a fan to dissipate heat from the motor. Meanwhile, the heat generated by the heat-conducting pad and the heat-conducting rod can be absorbed by the heat-conducting rod. The heat-conducting rod can also dissipate heat through contact with the water in the water tank and with the outside air, thereby achieving the purpose of heat dissipation of the motor and improving the heat dissipation efficiency of the motor. However, the above utility model patent has obvious defects. The device needs to rely on the fan for active heat dissipation, which consumes additional power and is not energy-efficient. The whole structure is fixed and cannot be quickly disassembled and installed, making it inconvenient for later inspection and maintenance. The heat dissipation method is singular, the air outlet direction is fixed, and the heat dissipation uniformity is poor. It is difficult to meet the requirements of efficient heat dissipation, energy saving and detachable use. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 6 An embodiment of this utility model is provided: a detachable high-efficiency energy-saving motor heat dissipation device, including a drive motor 1, a drive gear 3 fixedly connected to the output end of the drive motor 1, a first protective shell 4 slidably connected to the outer wall of the drive motor 1, a transmission gear 5 meshing with the outer wall of the drive gear 3, a cooling fan 6 fixedly connected to one end of the transmission gear 5, a pulley group 7 fixedly connected to the outer surface of the cooling fan 6, a transmission rod 8 fixedly connected to the inner wall of the pulley group 7, a reciprocating groove 9 opened on the outer surface of the transmission rod 8, a drive slide 10 slidably connected to the inner wall of the reciprocating groove 9, a plurality of movable frames 11 slidably connected to the outer surface of the drive slide 10, an air outlet louver 12 fixedly connected to one side of each of the plurality of movable frames 11, and an installation mechanism 2 slidably connected to the outer wall of the drive motor 1.

[0033] Specifically, the drive motor 1 is slidably and detachably connected to the first protective shell 4 and the second protective shell 201, facilitating partial disassembly and maintenance. Simultaneously, the drive motor 1 provides heat dissipation through its transmission during operation, requiring no additional power input. The drive motor 1 provides the core power, and its output end fixed drive gear 3 meshes with the transmission gear 5, driving the cooling fan 6 to rotate for basic heat dissipation. The cooling fan 6 drives the transmission rod 8 to rotate synchronously via the pulley group 7 fixed to its outer surface. The reciprocating groove 9 of the transmission rod 8 drives the drive slide 10 to slide back and forth, thereby driving multiple movable frames 11 in linkage to achieve angle adjustment and reciprocating opening and closing of the air outlet louvers 12 to optimize air outlet efficiency. The mounting mechanism 2, slidably connected to the outer wall of the drive motor 1, allows for quick assembly and disassembly of the device. The first protective shell 4 is slidably connected to the drive motor 1, facilitating internal component inspection. Overall, the device achieves efficient heat dissipation and convenient maintenance.

[0034] Please see the appendix Figure 3 Appendix Figure 4 and attached Figure 5 The installation mechanism 2 includes a second protective shell 201, the inner wall of the second protective shell 201 is slidably connected to the outer wall of the first protective shell 4, the inner wall of the first protective shell 4 is slidably connected to a drive rod 202, the inner wall of the drive rod 202 is meshed with a driven gear 203, the outer surface of the driven gear 203 is fixedly connected to a linkage crank 204, the inner wall of the first protective shell 4 is rotatably connected to a docking claw 205, the inner wall of the second protective shell 201 is provided with an installation groove 206, the inner wall of the second protective shell 201 is fixedly connected to a locking pin 207, and the inner wall of the drive rod 202 is slidably connected to an elastic locking pin 208.

[0035] Specifically, the second protective shell 201 serves as the installation base, with its inner wall slidably connected to the first protective shell 4. This allows for quick docking and separation of the two shells, facilitating the maintenance of internal components. Pushing the drive rod 202, which is slidably connected to the inner wall of the first protective shell 4, drives the driven gear 203, which meshes with it, to rotate. The driven gear 203 then drives the linkage crank 204, which is fixed on the outer surface, to move in tandem. This causes the docking claw 205, which is rotatably connected to the inner wall of the first protective shell 4, to engage with the mounting groove 206 of the second protective shell 201. The docking claw 205 then encircles the locking post 207, achieving initial locking. Simultaneously, the elastic locking pin 208, which is slidably connected to the inner wall of the drive rod 202, engages with the inner wall of the first protective shell 4 to complete a secondary locking, ensuring the device is securely installed. The entire device achieves the dual functions of convenient disassembly and assembly and stable fixation.

[0036] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 6The outer wall of the transmission gear 5 is rotatably connected to the inner wall of the first protective shell 4, the outer surface of the pulley group 7 is rotatably connected to the inner wall of the first protective shell 4, the outer surface of the transmission rod 8 is rotatably connected to the inner wall of the first protective shell 4, the two ends of the air outlet louver 12 are rotatably connected to the inner wall of the first protective shell 4, a protective net 13 is fixedly connected to one side of the first protective shell 4, and a rear half cover 14 is fixedly connected to the other side of the first protective shell 4.

[0037] Specifically, the first protective housing 4 provides overall support and protection for the device. Its inner wall is rotatably connected to the transmission gear 5, the pulley group 7, and the transmission rod 8, which can limit the operating trajectory of each transmission component, ensure a smooth and reliable transmission process, and prevent component deviation and jamming. The two ends of the air outlet louver 12 are rotatably connected to the inner wall of the first protective housing 4 to ensure smooth and stable adjustment of the air outlet angle. The protective net 13 fixed on one side of the first protective housing 4 can block the entry of external foreign objects, and the rear half cover 14 fixed on the other side can close the rear end of the device to prevent dust and debris from entering the internal structure and ensure the safe and stable operation of the device.

[0038] Please see the appendix Figure 2 Appendix Figure 3 and attached Figure 5 Multiple friction teeth 15 are fixedly connected to the outer wall of the docking claw 205. The outer wall of the friction teeth 15 is engaged with the outer surface of the mounting groove 206. The outer surface of the driven gear 203 is rotatably connected to the inner wall of the first protective shell 4. The outer surface of the elastic locking pin 208 is engaged with the inner wall of the first protective shell 4. Multiple heat dissipation fins 16 are fixedly connected to the top of the second protective shell 201. A connecting pipe 17 is fixedly connected to the inner wall of the multiple heat dissipation fins 16.

[0039] Specifically, multiple friction teeth 15 on the outer wall of the docking claw 205 engage with the outer surface of the mounting groove 206, precisely positioning and locking the first protective shell 4 and the second protective shell 201 to prevent displacement after installation and ensure connection stability. The driven gear 203 rotates with the inner wall of the first protective shell 4, ensuring smooth and uninterrupted transmission. This, combined with the linkage crank 204, drives the docking claw 205 to move precisely. The elastic locking pin 208 engages with the inner wall of the first protective shell 4, achieving secondary locking and further preventing loosening during operation. Multiple heat dissipation fins 16 on the top of the second protective shell 201 increase the heat dissipation area, and the inner wall connecting pipe 17 conducts heat from the fins, accelerating heat dissipation.

[0040] Working principle: During operation, the drive motor 1 outputs power, which drives the drive gear 3 fixed at its output end to rotate synchronously with the shaft. Meanwhile, the drive gear 3 meshes with the transmission gear 5, thereby driving the cooling fan 6 to rotate. The cooling fan 6 adopts an arc-shaped swept blade structure, and the fan blade edge is equipped with guide teeth. When rotating, it can form a negative pressure suction effect, efficiently sucking in external cold air and blowing it in a direction to the motor surface to complete basic air cooling. Then it is discharged from the position of the air outlet louver 12 to complete basic air cooling. At the same time, the opening and closing of the air outlet louver 12 can increase the heat exchange area of ​​the motor surface and accelerate the motor heat dissipation. The cooling fan 6 transmits power through the pulley group 7 on the outer surface, driving the transmission rod 8 to rotate synchronously. The reciprocating groove 9 on the transmission rod 8 drives the drive slide 10 to reciprocate linearly as it rotates. The drive slide 10 then drives multiple movable frames 11 to move in linkage, so that the air outlet louver 12 can realize angle adjustment and reciprocating opening and closing, improving the uniformity of air outlet and heat dissipation efficiency. The drive motor 1 is slidably and detachably connected to the first protective shell 4 and the second protective shell 201. The device relies on the motor's own power to run throughout the process, without the need for additional energy input, and is also easy to disassemble and maintain in parts.

[0041] During installation, the second protective housing 201 slides into the first protective housing 4 for quick docking. The drive rod 202 is pushed to rotate the driven gear 203. The driven gear 203 then drives the docking claw 205 to swing through the linkage crank 204, locking it into the mounting groove 206 on the second protective housing 201, completing the initial locking. When the drive rod 202 moves into place, the elastic locking pin 208 engages with the inner wall of the first protective housing 4 to form a secondary lock, ensuring reliable connection of the device. During disassembly, the locking can be released by reversing the operation, realizing the quick separation of the two housings, facilitating internal maintenance. The whole device achieves the functions of detachable installation and stable fixation.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
