Description

Technical Field

[0001] This utility model relates to the technical field of inverter protection equipment, specifically to an integrated dustproof protective cover for inverter heat dissipation. Background Technology

[0002] A frequency converter is a power control device that uses frequency conversion technology and microelectronics technology to control an AC motor by changing the frequency of the motor's power supply. A frequency converter mainly consists of a rectification (AC to DC), filtering, inversion (DC to AC), braking unit, drive unit, detection unit, and microprocessor unit.

[0003] Referring to a patented protective cover for a frequency converter (publication number: CN210157079U), it prevents the frequency converter from being interfered with by dust, reduces the influence of other electrical components in the control cabinet on the frequency converter, and reduces the influence of the temperature inside the control cabinet on the operation of the frequency converter. Through the setting of the upper and lower connecting parts, the protective cover can be flexibly disassembled, which is simple and quick to operate, convenient to install, and saves time and effort. During the disassembly process, no damage is caused to the protective cover, frequency converter, and control cabinet. However, the frequency converter generates a lot of heat during operation, and its sealed structure design will seriously affect the heat dissipation of the frequency converter, which will lead to the aging and damage of the internal electronic components of the frequency converter and affect the service life of the frequency converter.

[0004] Therefore, an integrated dustproof protective cover for inverter heat dissipation is proposed to solve the above problems. Utility Model Content

[0018] Example

[0019] Please refer to the following: Figure 1-4 This utility model discloses an integrated dustproof protective cover for inverter heat dissipation, comprising a base plate 1 and an inverter body 3. A protective box 2 is provided on the top of the base plate 1. A base plate 4 is provided on the bottom of the inner wall of the protective box 2. Mounting brackets 5 are slidably connected to the top two sides of the base plate 4. The inverter body 3 is connected and fixed to the mounting brackets 5. Heat dissipation boxes 6 are fixedly connected and communicated on both sides of the protective box 2. An air intake fan 7 is provided in each heat dissipation box 6 on the side closer to the protective box 2. A first filter 9 and a second filter 10 are detachably connected to the side of each heat dissipation box 6 away from the protective box 2. Breathable mesh plates 8 are provided on both sides of the top of the protective box 2.

[0020] The heat dissipation box 6 has mounting rails 11 fixedly connected to the top and bottom of the inner wall. Each No. 1 filter 9 and No. 2 filter 10 is detachably connected to the corresponding mounting rail 11. Each pair of corresponding mounting rails 11 has a limiting groove 12 on one side close to each other. Each No. 1 filter 9 and No. 2 filter 10 has a limiting slide plate 13 fixedly connected to the top and bottom of the upper and lower parts. Each limiting slide plate 13 is slidably connected to the corresponding limiting groove 12.

[0021] The protective box 2 is fixedly connected to the top center of the drive motor 14. The output end of the drive motor 14 passes through the protective box 2 and is connected to the cleaning box 15. The cleaning box 15 is detachably connected to the output end of the drive motor 14. The bottom of the inner wall of the cleaning box 15 is fixedly connected to the servo motor 16. The output end of the servo motor 16 is fixedly connected to the mounting plate 17. The top of the mounting plate 17 is provided with a dust removal plate 18. A detachable power supply is provided inside one side of the cleaning box 15. The servo motor 16 is electrically connected to the detachable power supply inside the cleaning box 15.

[0022] A dual-head motor 19 is fixedly connected to the middle of the inner wall of the base plate 4. Both ends of the dual-head motor 19 are fixedly connected to screws 20. The end of each screw 20 is rotatably connected to the inner wall of the base plate 4. A slider 21 is threadedly connected to the middle of each screw 20. The top of each slider 21 passes through the top groove of the base plate 4 and is fixedly connected to the corresponding mounting bracket 5. A controller is set on one side of the protective box 2. The air intake fan 7, drive motor 14, servo motor 16 and dual-head motor 19 are all electrically connected to the controller on the side wall of the protective box 2.

[0023] Specifically, in use, this utility model uses an intake fan 7 to deliver external cold air into the protective box 2. Simultaneously, filter screens 9 and 10 effectively filter and adsorb dust particles in the incoming air. The sliding connection between the limiting slide plate 13 and the limiting sliding groove 12 allows for quick assembly and disassembly of filter screens 9 and 10 and their corresponding mounting rails 11, thus improving the convenience and efficiency of filter replacement and preventing filter blockage that could affect heat dissipation. The breathable mesh plate 8 allows hot air from the protective box 2 to escape. The drive motor 14 rotates the cleaning box 15, causing it to rotate sequentially below each breathable mesh plate 8. The servo motor 16 drives the mounting plate 17 to rotate, causing the dust removal plate 18 to clean the breathable mesh plates 8. This effectively prevents excessive dust accumulation on the breathable mesh plates 8 after prolonged use, thus further improving the dustproof effect of the equipment.

[0024] By starting the dual-head motor 19 to drive the screw 20 to rotate, the two screws 20 drive the corresponding slider 21 to slide, thereby causing the two mounting brackets 5 to move closer or further apart. This effectively adjusts the inverter body 3 according to different sizes, ensuring the convenience and adaptability of the equipment.

[0025] All electrical components mentioned in the article are electrically connected to the controller and power supply. The controller can be a conventional and known device such as a computer that can perform control functions, and it is a publicly available power connection technology, so it will not be described in detail.

[0026] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
