[0002] The power distribution system is a power network system composed of a variety of power distribution equipment and power distribution facilities that transforms voltage and directly distributes electric energy to end users. In the low-voltage power distribution system, most of the distribution cabinets, electrical cabinets, control boxes, etc. are relatively closed, and play an irreplaceable role in daily life and industrial construction. With the widespread application of low-voltage distribution cabinets, in order to facilitate operation, low-voltage distribution cabinets are often installed in outdoor environments. Low-voltage distribution cabinets usually refer to distribution cabinets with AC voltage of 1000V and below, which are used to distribute electric energy to various terminal electrical equipment.

When in use, the motor 10 is started to drive the threaded long rod 8 to rotate. When the threaded long rod 8 rotates, The sleeve-type square shell 12 which is threadably matched with it and is penetrated and limited by the limiting round rod 11 moves downward.

When the inner threaded sleeve 13035 moves, it drives the sliding circular plate 13036 on one side to move together. When the extension spring 1303 drives the hollow air cushion 1301 to expand and recover, it drives the inner threaded sleeve 13035 to move back together. The sliding circular plate 13036 is arranged on one side of the inner threaded sleeve 13035 to slide and limit the inner threaded sleeve 13035 that moves back.

A dust filter hole 1403 is provided on the side to filter dust particles to block the dust particles, and the electric push rod 1406 is started to drive the top inclined scraper 1407 to move upward. When the inclined scraper 1407 moves upward, the positions where the dust filter holes 1403 are provided on both sides of the frame cover 1401 are scraped and cleaned. When the inclined scraper 1407 moves upward, it drives the bottom frame plate 1408 and the sleeve sealing plate 1409 at the bottom to move upward together, and the driving shaft connection of the electric push rod 1406 is wrapped and covered by arranging the bottom frame plate 1408 and the sleeve sealing plate 1409 at the bottom of the inclined scraper 1407.

[0057] When the present invention is operated and used, the motor 10 is started to drive the threaded long rod 8 to rotate. When the threaded long rod 8 rotates, it drives the sleeve-type square shell 12 that is threadedly matched with it and is penetrated and limited by the limiting round rod 11 to move downward. When the sleeve-type square shell 12 moves downward, it drives the elastic protection device 13 to move downward as a whole and surround and cover the cabinet 1. At this time, the elastic protection device 13 can elastically contact with the flying debris to rebound the debris and reduce the damage to the sleeve-type square shell 12. At the same time, the heat dissipation device 14 can be used to perform ventilation and heat dissipation on the wrapped and covered cabinet 1. When the cabinet 1 needs to be repaired or other operations, the motor 10 drives the threaded long rod 8 to reverse so that the elastic protection device 13 moves upward as a whole to the top of the cabinet 1. The debris flying in the surrounding area of ​​the cabinet 1 will first contact with the interception device 14. The structure 1302 contacts and is intercepted by the interception mechanism 1302. When the interception mechanism 1302 applies pressure to the interception mechanism 1302, it is transmitted to the hollow air cushion 1301 to elastically compress the hollow air cushion 1301. When the hollow air cushion 1301 is compressed, the internal extension spring 1303 is also compressed. By arranging a hollow air cushion 1301 made of elastic material on the outside of the sleeve-type square shell 12, it is elastically in contact with the flying debris, the debris is rebounded and the damage to the hard baffle is reduced. After the hollow air cushion 1301 loses the pressure of the impact of the debris, the internal extension spring 1303 pushes the hollow air cushion 1301 to expand and recover to the initial state through the extension force. By arranging a middle connecting rod 1305 at the oblique angle position of the inner wall of the hollow air cushion 1301, the surface of the hollow air cushion 1301 at the oblique angle is stabilized. The middle connecting rod 1305 and the hollow air cushion 1301 are elastically contacted by respectively arranging a first arc-shaped gasket 1304 and a second arc-shaped gasket 1306 made of elastic rubber between the middle connecting rod 1305 and the hollow air cushion 1301. Flying debris will contact the spiral retaining bar 13032 on one side of the circular connecting plate 13031 first, and the hollow air cushion 1301 is pressurized by colliding the spiral retaining bar 13032 and the circular connecting plate 13031. A plurality of spiral retaining bars 13032 are arranged on the outside of the hollow air cushion 1301 to preliminarily intercept the flying debris. When the spiral retaining bar 13032 is gradually damaged by the impact of debris for a long time, the rounded grip bar 13033 can be twisted to drive the circular connecting plate 13031 and the threaded short rod 1303. 4 is rotated, and when the threaded short rod 13034 rotates, it cooperates with the thread of the internal threaded sleeve 13035 to remove the circular baffle as a whole from the outside of the hollow air cushion 1301, and the spiral baffle 13032 is removed and reinstalled by the threaded short rod 13034 and the thread of the internal threaded sleeve 13035. By arranging the internal threaded sleeve 13035 and the circular shell 13037 in sliding connection inside the hollow air cushion 1301, the shape of the hollow air cushion 1301 elastically connected by the extension spring 1303 is stabilized. When the hollow air cushion 1301 is compressed, the internal threaded sleeve 13035 of the inner wall is pushed to move into the circular shell 13037. When the internal threaded sleeve 13035 moves, it drives the sliding circular plate 13036 on one side to move together.When the extension spring 1303 drives the hollow air cushion 1301 to expand and recover, it drives the internal threaded sleeve 13035 to move back together. A sliding circular plate 13036 is set on one side of the internal threaded sleeve 13035 to slide and limit the internal threaded sleeve 13035 that moves back. The high-pressure air pump 1405 is used to evacuate the inside of the frame cover 1401 so that the gas inside the cabinet 1 is discharged from the heat dissipation circular hole 15 below the partition plate 1402, and the gas outside the cabinet 1 enters the frame cover 1401 from the dust filter hole 1403 and passes through the heat dissipation circular hole 15 above the partition plate 1402 to enter the cabinet 1 to form a ventilation gas flow path. The partition plate 1402 is set inside the frame cover 1401 to The inner area of ​​the frame cover 1401 is divided into an air intake area and an exhaust area so that the gas flows in a ventilation manner. The dust particles are blocked by opening dust filter holes 1403 on both sides of the frame cover 1401 to facilitate filtering dust particles. The electric push rod 1406 is started to drive the top inclined scraper 1407 to move upward. When the inclined scraper 1407 moves upward, the positions where the dust filter holes 1403 are opened on both sides of the frame cover 1401 are scraped and cleaned. When the inclined scraper 1407 moves upward, the bottom frame plate 1408 and the sleeve sealing plate 1409 at the bottom are driven to move upward together. The bottom frame plate 1408 and the sleeve sealing plate 1409 are set at the bottom of the inclined scraper 1407 to wrap and cover the driving shaft connection of the electric push rod 1406.
