The device includes a mounting frame 1, with a connecting plate fixedly connected to the top of the mounting frame 1. A cleaning and dust extraction mechanism is set up to start a motor 1, which synchronously drives a rotating soft brush to move. Simultaneously, a second motor is started during the movement of the rotating soft brush, which also drives the rotating soft brush to rotate, thus cleaning the surface of the fan blades.

Description

Technical Field

[0001] This utility model relates to the field of cooling technology for electrical engineering and automation components, specifically a cooling device for electrical components used in electrical engineering and automation. Background Technology

[0002] In the field of electrical engineering and automation, with the continuous development of technology and the increasing complexity of equipment, electrical components (such as control boards, frequency converters, inverters, etc.) generate a large amount of heat during operation. If this heat cannot be dissipated in a timely and effective manner, it will lead to excessively high temperatures in the electrical components. High temperatures will accelerate the aging process of the electrical components, shorten their service life, and may even cause equipment damage, thus requiring cooling devices for the electrical components.

[0003] According to the patent application disclosed in CN 222547303 U, "An electrical component cooling device includes an upper connecting pipe and two spacer plates installed on both sides of the bottom end of the upper connecting pipe. A lower connecting pipe is installed on one end of the two spacer plates opposite to the upper connecting pipe. An inlet pipe is connected to the middle of the upper connecting pipe, and an outlet pipe is connected to the lower connecting pipe. Several cold pipe assemblies are provided, and the several cold pipe assemblies are evenly installed between the upper connecting pipe and the lower connecting pipe. A drive component for driving the several cold pipe assemblies to rotate is installed on the upper connecting pipe."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] In the process of using this utility model, when it is necessary to clean the fan blades, the drive screw rotates alternately in both directions, thereby driving the lifting block to move up and down along the guide rod, which in turn drives the cleaning ring to scrape and clean the fan blades using a scraper and a cleaning brush. However, in actual use, the device scrapes and cleans the fan blades by scraping, which easily causes the scraped dust to scatter in the air during the cleaning process. As a result, after the cleaning mechanism stops running, the scattered dust is easy to re-adhere to the fan blades, resulting in poor cleaning effect and requiring more cleaning time in subsequent use. Therefore, there is a need to improve a cooling device for electrical components used in electrical engineering and automation. Utility Model Content

[0031] Furthermore, vertical grooves are provided at the corresponding positions of the limiting frame 7 and the support frame 516, and the support frame 516 is slidably connected in the vertical grooves, so as to synchronously drive the rotating soft brush 518 to move up and down.

[0032] Furthermore, the support frame 516 has holes at the corresponding positions of the rotating soft brush 518, and the rotating soft brush 518 is rotatably connected in the holes, which facilitates driving the rotating soft brush 518 to rotate.

[0033] Furthermore, the dust collection assembly 52 includes a dust collection box 521, which is fixedly connected to the right side of the connecting plate 2. A negative pressure fan 522 is fixedly connected to the bottom of the dust collection box 521, and a corrugated telescopic tube 523 is fixedly connected to the top of the dust collection box 521.

[0035] Based on the existing technology's requirement to complete cooling at a specific location, please refer to [link / reference needed]. Figure 5Furthermore, in conjunction with Embodiment 1, the cooling mechanism 4 includes a third motor 41, which is fixedly connected to the top of the second mounting frame 3. A first gear 42 is fixedly connected to the output end of the third motor 41. A second gear 43 is rotatably connected inside the second mounting frame 3. A hollow rotating shaft 44 is fixedly connected to the inner side of the second gear 43. A fan blade 45 is fixedly connected to the outside of the hollow rotating shaft 44. An inlet pipe 46 is fixedly connected inside the second mounting frame 3. An outlet pipe 47 is fixedly connected inside the first mounting frame 1, which facilitates improved cooling efficiency.

[0036] Furthermore, the hollow rotating shaft 44 has grooves at positions corresponding to the liquid inlet pipe 46 and the liquid outlet pipe 47, and the hollow rotating shaft 44 is rotatably connected to the outside of the liquid inlet pipe 46 and the liquid outlet pipe 47. Gear 1 42 and gear 2 43 mesh with each other, and liquid inlet channels are provided inside the fan blade 45 and the hollow rotating shaft 44 to facilitate synchronous rotation of the fan blade 45.

[0037] In actual operation, when the device is in use, the control method of this utility model is controlled by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail. The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The supply of power is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0038] First, the device is fixed next to a suitable electrical component for electrical engineering and automation. During the cooling process, the cooling mechanism 4 connects to an external coolant, which is then delivered to the inlet pipe 46. The coolant is then delivered from the inlet pipe 46 to the hollow rotating shaft 44, and from the hollow rotating shaft 44 to the inlet channel inside the fan blade 45. At this time, the motor 3 41 is started synchronously, which drives the gear 1 42 to rotate. The gear 1 42 then drives the gear 2 43 to rotate, which in turn drives the fan blade 45 to rotate. Guided by the air guide plate 6, the coolant is blown to the designated position for cooling. During the continuous cooling process, the coolant is discharged from the outlet pipe 47. When it is necessary to clean the fan blade 45 later, the speed of the motor 3 41 is adjusted synchronously to make the fan blade 45 rotate slowly. At the same time, the cleaning and dust collection mechanism 5 starts the motor 1 512, which drives the connecting rod 51. 3. The connecting rod 513 rotates, and the roller 514 moves synchronously during the rotation. The roller 514 then moves the guide frame 515, which in turn moves the support frame 516. The support frame 516 moves along the guide of the limiting frame 7, which in turn moves the rotating soft brush 518. During the movement of the rotating soft brush 518, the second motor 517 is started, which drives the rotating soft brush 518 to rotate. This allows the rotating soft brush 518 to rotate synchronously during its movement, cleaning the surface of the fan blade 45. At the same time, the negative pressure fan 522 is started, and the dust is transported to the dust collection box 521 through the dust collection hood 519 and the dust collection pipe 5110. The dust is then filtered by the filter screen, keeping it inside the dust collection box 521. This prevents a large amount of dust from being scattered and re-adhering to the fan blade 45, thus improving the cleaning effect.
