DETAILED DESCRIPTION

[0023] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figure 1-Figure 6 An environmentally friendly power cabinet that is easy to dissipate heat is shown, including a cabinet body 1. The inner wall of the cabinet body 1 is provided with a driving mechanism and a cleaning mechanism controlled by the driving mechanism. The cleaning mechanism includes a cross bar 9 slidably connected to the inner wall surface of the cabinet body 1. An embedding groove 12 is provided at one end of the cross bar 9 close to the inner wall of the cabinet body 1. A semicircular scraper 13 is rotatably connected inside the embedding groove 12. The cleaning mechanism is controlled by the driving mechanism to make the semicircular scraper 13 slide inside the heat dissipation hole 2 to scrape off all the dust attached to the inside of the heat dissipation hole 2, thereby preventing dust from clogging the inside of the heat dissipation hole 2 and affecting the heat dissipation performance of the power cabinet, thereby avoiding the occurrence of safety hazards.

[0025] A limiting groove 14 is provided inside the cabinet 1, and a damping rod 15 and a spring 16 are provided inside the limiting groove 14. One end of the spring 16 away from the inner wall of the limiting groove 14 is fixedly connected to a clamping block 17, and one end of the clamping block 17 arranged inside the limiting groove 14 is fixedly connected to a limiting block 18. A heat dissipation hole 2 is provided at the bottom end of the cabinet 1, and the clamping block 17 can limit the semicircular scraper 13. When the semicircular scraper 13 slides to the clamping block 17, it will rotate due to the limitation of the clamping block 17, thereby cleaning the dust in the arc-shaped part of the heat dissipation hole 2, thereby increasing the cleaning range and further ensuring that the dust will not block the heat dissipation hole 2.

[0026] The control mechanism includes a support 3 fixedly mounted on the inner wall of the cabinet 1, a driving motor 4 is fixedly mounted on one end of the support 3 away from the inner wall of the cabinet 1, an output end of the driving motor 4 is fixedly connected to a driving gear 5, the inner wall of the cabinet 1 is rotatably connected to a driven gear 6, the driving gear 5 is meshed with the driven gear 6, and through the cooperation of the driving gear 5 and the driven gear 6, the driving motor 4 can drive the two gears to rotate at the same time, thereby utilizing the connection mechanism to drive the dust cleaning mechanism to operate, and clean the dust accumulated inside the heat dissipation hole 2 to prevent the dust from clogging the heat dissipation hole 2 and affecting the heat dissipation performance of the power cabinet.

[0027] A connecting mechanism is installed on the end face of the driven gear 6 away from the inner wall of the cabinet 1, and the connecting mechanism includes a connecting rod 7 rotatably connected to the end face of the driven gear 6, and bearings 8 are fixedly installed at both ends of the connecting rod 7. The driven gear 6 is connected to the bearing 8 at one end, and the bearing 8 at the other end is connected to the cross bar 9. The connecting mechanism can not only control the moving distance of the cleaning mechanism, but also enable the cleaning mechanism to move up and down inside the heat dissipation hole 2, so that the cleaning mechanism can repeatedly clean the heat dissipation hole 2 to ensure the cleanliness of the heat dissipation hole 2 after cleaning.

[0028] The inner wall of the cabinet 1 is provided with two slide grooves 11, and the two slide grooves 11 are respectively located on both sides of the heat dissipation hole 2. Both ends of the cross bar 9 are fixedly connected with sliders 10, and the slider 10 and the slide groove 11 cooperate with each other. The cleaning mechanism is arranged on the inner wall of the cabinet 1 through the cooperation of the slider 10 and the slide groove 11. The cooperation between the slider 10 and the slide groove 11 can not only provide conditions for the movement of the cross bar 9, but also limit the cross bar 9 to prevent the cross bar 9 from being driven by the driving mechanism, together with the semicircular scraper 13, from detaching from the heat dissipation hole 2, thereby losing the work of cleaning the heat dissipation hole 2.

[0029] A rotating groove 20 is provided inside the embedded groove 12, and a rotating block 21 is fixedly connected to one end of the semicircular scraper 13 located inside the embedded groove 12. The rotating block 21 cooperates with the rotating groove 20. The semicircular scraper 13 is rotatably connected to the cross bar 9 through the cooperation of the rotating block 21 and the rotating groove 20. Through the cooperation between the rotating block 21 and the rotating groove 20, the semicircular scraper 13 can rotate inside the embedded groove 12, so that the arc part of the heat dissipation hole 2 can be cleaned to prevent missed dust from accumulating in the arc, which will still affect the heat dissipation performance of the power cabinet.

[0030] An auxiliary mechanism is provided inside the semicircular scraper 13, and the auxiliary mechanism includes a top column 19 slidably connected to the inside of the semicircular scraper 13. A peak-shaped groove 23 is provided on the surface of the top column 19. The peak-shaped groove 23 is divided into a top groove 24 and a bottom groove 25. A protrusion 22 is fixedly connected to the inner wall of the semicircular scraper 13, and the protrusion 22 cooperates with the peak-shaped groove 23. Through the cooperation between the protrusion 22 and the peak-shaped groove 23, the top column 19 can pop outward and retract during the rotation of the semicircular scraper 13, and the dust scraped by the semicircular scraper 13 can be ejected to prevent the scraped dust from remaining in the heat dissipation hole 2 and causing blockage.

[0031] When the protrusion 22 is located inside the top groove 24, the end face of the top column 19 located on one side of the bottom groove 25 fits with the inner wall of the embedded groove 12. When the protrusion 22 is located inside the bottom groove 25, the end face of the top column 19 located on one side of the top groove 24 is located on the same horizontal plane as the end face of the semicircular scraper 13. When the semicircular scraper 13 does not rotate, part of the scraped dust remains in the outer end face of the top column 19 and the semicircular scraper 13, and some dust will fall out. When the semicircular scraper 13 rotates, the top column 19 will rotate and retract to push out the dust, and the dust that is not ejected will also be blown away by the airflow emitted from the heat dissipation hole 2.

[0032] The block 17 is located inside the heat dissipation hole 2, and the semicircular scraper 13 is slidably connected to the inside of the heat dissipation hole 2 through a control mechanism and cooperates with the block 17. The semicircular scraper 13 will be restricted by the plane of the block 17 and rotate, and will also restrict the inclined surface of the block 17, so that the block 17 retracts into the limiting groove 14, so that it will not rotate.

[0033] Working principle: After the power cabinet has been working in a dusty place for a long time, not only the surface of the electrical appliances inside the power cabinet will be adhered to dust, but also a large amount of dust will clog the inside of the heat dissipation holes 2, affecting the heat dissipation performance of the power cabinet. At this time, the driving mechanism can be used to drive the dust cleaning mechanism to clean the dust inside the heat dissipation holes 2 to prevent the dust from clogging the heat dissipation holes 2. During the entire dust cleaning process, the connecting mechanism will control the moving distance of the dust cleaning mechanism to ensure that the semicircular scraper 13 slides between the top and bottom ends of the heat dissipation holes 2, so that the dust cleaning mechanism repeatedly cleans the heat dissipation holes 2. When the semicircular scraper 13 slides down to the block 17, it will It is restricted by the plane of the block 17 and rotates. During the rotation, the dust on the arc-shaped part of the heat dissipation hole 2 is also scraped off. After the semicircular scraper 13 rotates 180 degrees, the driving mechanism will drive the cross bar 9 to move upward, and the semicircular scraper 13 will also stop rotating and cooperate with the inclined surface of the block 17 to push the block 17 open to prevent the block 17 from affecting the cleaning work. When the semicircular scraper 13 rises to the top block 17, it will repeat the rotation and scraping work again. When the semicircular scraper 13 rotates, the auxiliary mechanism will retract and push out the scraped dust, thereby completely cleaning the dust attached to the heat dissipation hole 2 of the power cabinet.
