Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, and in particular to a transformer outer wall maintenance and cleaning device. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components are the primary coil, the secondary coil, and the iron core. The transformer is equipped with multiple heat dissipation fins on its exterior to ensure proper heat dissipation.

[0003] However, after prolonged use, dust tends to accumulate between the heat dissipation fins of a transformer. When cleaning the exterior of the transformer, the dust and debris between the heat dissipation fins are difficult to remove, and long-term accumulation will affect the heat dissipation function of the heat dissipation fins.

[0004] For example, a patent entitled "A Surface Dust Removal Device for Transformers" (patent application number: CN202022165356.4) discloses a surface dust removal device for transformers. It utilizes the arrangement of a first scraper and a second scraper, which can slide and engage between two adjacent fins. When the connecting plate drives the first scraper to move up and down between the heat dissipation fins, it can clean the dust between the heat dissipation fins. The parallel movement of the connecting plate allows the second scraper to scrape off the dust that has fallen off, thereby ensuring the cleanliness between the heat dissipation fins. However, the scraped dust still remains near the transformer and may re-adhere to the heat dissipation fins, so the efficiency of use needs to be improved.

[0005] Therefore, it is necessary to propose a transformer external wall maintenance and cleaning device to solve the above problems. Utility Model Content

The wind power components include a wind hole, a sliding channel, a baffle, a round hole, a spring, and a first magnet. The wind hole is opened on the wall of the wind box, the sliding channel is opened on the end of the wind box near the square tube, the baffle is slidably disposed inside the sliding channel, the round hole is opened on the baffle, the first magnet is fixedly connected to the end of the baffle located outside the wind box, the spring is fixedly connected between the inner wall of the wind box and the baffle, a second magnet is provided on the side of the first magnet facing away from the baffle, the second magnet is fixedly connected to the square tube, the first magnet and the second magnet repel each other, and a scraper head is fixed at the end of the wind box away from the square tube.

[0008] Preferably, there are multiple air boxes, which are evenly distributed.

[0009] Preferably, a connecting assembly is provided between the air box and the square tube. The connecting assembly includes a fixed base, a rotating shaft, a circular groove, and a torsion spring.

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides, for example Figures 1-5 The transformer exterior wall maintenance and cleaning device shown includes a square tube 1, on which air boxes 2 are mounted. Multiple air boxes 2 are evenly distributed. A scraper head 18 is mounted at the end of each air box 2 furthest from the square tube 1. The scraper head 18 can be fixed to the air box 2 via a plug-in connection for easy replacement. The scraper head 18 can extend between two adjacent heat dissipation fins to scrape and clean the dust between the fins.

[0024] Each pair of adjacent air boxes 2 is connected by a second air duct 12, so that multiple air boxes 2 are connected and form a whole.

[0025] A first air duct 11 is connected to the square tube 1. The first air duct 11 is connected to the air pump (not shown in the figure). A filter box can also be installed to cooperate with the air pump to filter the dust drawn in. One of the air boxes 2 is connected to the square tube 1 by a telescopic hose 13. A handle 10 is fixedly connected to the square tube 1, and the operator can hold the handle 10 to use the device.

[0026] A connecting assembly is provided between the air box 2 and the square tube 1. The connecting assembly includes a fixed base 14, a rotating shaft 15, a circular groove 16, and a torsion spring 17. The fixed base 14 is fixedly connected to the square tube 1, the rotating shaft 15 is rotatably connected to the fixed base 14, the air box 2 is fixedly connected to the rotating shaft 15, the circular groove 16 is formed on the fixed base 14 and surrounds the outside of the rotating shaft 15, the torsion spring 17 is fitted on the rotating shaft 15, one end of the torsion spring 17 is fixedly connected to the inner wall of the circular groove 16, and the other end of the torsion spring 17 is fixedly connected to the air box 2. The torsion spring 17 can assist the air box 2 in resetting.

[0027] To facilitate the timely removal of dust after scraping and cleaning, wind-powered components are installed at both the top and bottom of the wind box 2. Each wind-powered component includes an air hole 3, a sliding channel 4, a baffle 5, a round hole 6, a spring 7, and a first magnet 8. The air hole 3 is located on the wall of the wind box 2. The sliding channel 4 is located at the end of the wind box 2 closest to the square tube 1. The baffle 5 is slidably positioned inside the sliding channel 4. The round hole 6 is located on the baffle 5. The first magnet 8 is fixedly connected to the end of the baffle 5 located outside the wind box 2. The spring 7 is fixedly connected between the inner wall of the wind box 2 and the baffle 5. A second magnet 9 is located on the side of the first magnet 8 facing away from the baffle 5. The second magnet 9 is fixedly connected to the square tube 1, and the first magnet 8 and the second magnet 9 engage in a repulsive relationship.

[0028] Specifically, the operator holds the handle 10 and inserts the scraper head 18 between two adjacent heat dissipation fins. When scraping downwards, the end of the air box 2 near the scraper head 18 tilts upwards, and the dust concentrates below the air box 2. The first magnet 8 located at the upper position abuts against the corresponding second magnet 9, while the first magnet 8 located at the lower position is offset from the corresponding second magnet 9. In the lower position of the air force component: the return force of the spring 7 pushes the baffle 5 to slide towards the square tube 1, so that the air hole 3 and the round hole 6 are connected. The dust after scraping can be sucked in through the first air duct 11, the telescopic hose 13, the air box 2, the round hole 6, and the air hole 3. The air hole 3 located at the upper position is in a closed state to ensure concentrated air force and improve the dust cleaning effect.

[0029] When the dust is pushed upwards, the end of the air box 2 near the scraper head 18 tilts upwards, and the dust is concentrated above the air box 2. The first magnet 8 located at the lower position abuts against the corresponding second magnet 9, while the first magnet 8 located at the upper position is offset from the corresponding second magnet 9. In the wind power component located at the upper position: the return force of the spring 7 pushes the baffle 5 to slide towards the square tube 1, so that the air hole 3 and the round hole 6 are connected. The dust after being pushed and scraped can be sucked through the first air pipe 11, the telescopic hose 13, the air box 2, the round hole 6 and the air hole 3. The air hole 3 located at the lower position is in a closed state to ensure that the wind force is concentrated and improve the dust cleaning effect.

[0030] By setting up structures such as the air box 2, scraper head 18, and wind power components, dust between the heat dissipation fins can be pushed and scraped cleaned. At the same time, the dust can be sucked away in time, and the concentrated wind force ensures the dust cleaning effect and improves the efficiency of the transformer outer wall maintenance and cleaning device.

[0031] After cleaning, under the restoring force of the torsion spring 17 and the repulsive force of the upper and lower sets of first magnets 8 and second magnets 9, the air box 2 is reset (refer to...). Figure 1 , Figure 2With the air vent 3 closed, the air box 2 vibrates slightly during this process, shaking off any residual dust on the scraper head 18 for easier subsequent use.
