Description

Technical Field

[0001] The present invention relates to the field of distribution cabinets, and particularly to a distribution cabinet that is convenient for maintenance. Background Art

[0002] A distribution cabinet is a device used to receive electrical energy from a generator, transformer, or other power source and distribute it to various circuits or devices. Distribution cabinets play an important role in many fields, including electricity, industry, transportation, petroleum, and chemical industry. In the electricity field, the distribution cabinet undertakes the distribution control and protection work of the power system; in the industrial field, it is responsible for the electrical control and protection of production lines and equipment; in the transportation field, it is widely used in the electrical control and protection of transportation facilities such as railways, subways, and highways. In addition, distribution cabinets are also widely used in fields such as construction, IT, medical, and military.

[0003] In the prior art, when the distribution cabinet is impacted, the staff cannot discover it in time. During this delay period, the impact may have caused damage to the electrical components inside the distribution cabinet, such as wire short circuits and component looseness. These problems may further lead to serious safety accidents such as fires and electric shocks. Therefore, a distribution cabinet that is convenient for maintenance is proposed. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that in the prior art, when the distribution cabinet is impacted, the staff cannot discover it in time. During this delay period, the impact may have caused damage to the electrical components inside the distribution cabinet, such as wire short circuits and component looseness.

[0011] The alarm device is arranged on the cabinet body and is used for alarm prompting.

[0012] The controller is arranged on the side of the cabinet, fixedly connected to the side surface of the cabinet, and electrically connected to the power equipment.

[0013] When the two sides of the distribution cabinet are hit, the anti-collision device can effectively play a buffering role and reduce the impact force of the cabinet when it is hit. The anti-collision device starts to drive the heat dissipation device, which can effectively cool the cabinet to prevent the internal electrical components from generating a lot of heat due to short circuit, overload or mechanical damage when the distribution cabinet is hit, which may cause a fire.

The four buffer plates are slidably connected to the four rectangular grooves, and their sliding directions are horizontally set and parallel to the front of the cabinet.

[0017] The two anti-collision wind plates are vertically arranged, perpendicular to the front side of the cabinet body, and the two anti-collision wind plates are respectively arranged on both sides of the four buffer plates, and are respectively fixedly connected to the other ends of the four buffer plates.

[0023] The second rack is parallel to the first rack, is located behind the linkage gear, and is meshed with the linkage gear. One end of the second rack is fixedly connected to the right anti-collision plate.

[0024] When the left side of the distribution cabinet is hit, the thrust generated by the impact drives the left anti-collision wind plate to move right, and the left anti-collision wind plate moves to the right and drives the first rack to move to the right. The first rack moves to the right and in turn drives the cleaning brush to move to the right and the linkage gear to rotate.

[0025] When the left anti-collision wind plate drives the first rack to move rightward, the first rack moves rightward and drives the cleaning brush to move rightward. The cleaning brush moves rightward to clean the filter to prevent dust, particles and other impurities from clogging the filter and causing a decrease in the heat dissipation effect.

[0119] By providing a temperature sensor, it is convenient for the staff to observe the temperature condition inside the cabinet 1.

[0120] Working principle: When the left side of the distribution cabinet is hit, the thrust generated by the impact drives the left anti-collision wind plate 403 to move right, and the left anti-collision wind plate 403 moves right, driving the first rack 406 to move right, and the first rack 406 moves right, which in turn drives the cleaning brush 407 to move right and the linkage gear to rotate.

[0121] When the left anti-collision wind plate 403 drives the first rack 406 to move rightward, the first rack 406 moves rightward and drives the cleaning brush 407 to move rightward, and the cleaning brush 407 moves rightward to clean the filter 405 to prevent dust, particles and other impurities from clogging the filter 405, thereby reducing the heat dissipation effect; When the left windshield 403 moves to the right and drives the linkage gear to rotate, the linkage gear rotates and drives the second rack to move to the left, and the second rack moves to the left and drives the right windshield 403 to move to the left; At this time, the two anti-collision wind plates 403 move toward each other, and the two anti-collision wind plates 403 move toward each other to squeeze the plurality of shock-absorbing springs 404.

The sound produced by the knocking rods 604 repeatedly knocking the gong 603 effectively attracts the attention of the staff, so that they can respond quickly, check the status of the distribution cabinet, evacuate personnel or take emergency maintenance measures, etc.

[0123] When the right side of the distribution cabinet is hit, the working process is as above.

[0124] When the left side of the power distribution cabinet is blown by wind, the left wind shield 403 moves to the right under the action of wind force, and the left wind shield 403 moves to the right, driving the first rack 406 to move to the right, and the first rack 406 moves to the right, driving the linkage gear to rotate, and the linkage gear rotates to drive the second rack to move to the left, and the second rack moves to the left, driving the right wind shield 403 to move to the left; At this time, the two anti-collision wind plates 403 move toward each other, and the two anti-collision wind plates 403 move toward each other to squeeze the plurality of shock-absorbing springs 404. Under the action of the elastic force of the plurality of shock-absorbing springs 404, the cabinet body 1 is buffered and protected, and under the action of the reaction force of the plurality of shock-absorbing springs 404, the two anti-collision wind plates 403 return to their original positions.

[0125] When the two wind-proof plates 403 move toward each other, the two wind-proof plates 403 move toward each other to squeeze the two elastic airbags 502 respectively, and drive the transmission plate 507 to move rightward; When the two anti-collision wind plates 403 move toward each other and squeeze the two elastic air bags 502 respectively, at this time, the heat dissipation liquid in the two elastic air bags 502 passes through the two liquid outlet pipes 505 respectively, and then is sprayed from the two spray heads 504 to the side surface of the cabinet 1 respectively. The heat dissipation liquid adheres to the side surface of the cabinet 1 and absorbs the heat of the cabinet 1, thereby effectively cooling the cabinet 1; When the two anti-collision wind plates 403 move toward each other and drive the transmission plate 507 to move rightward, the transmission plate 507 moves rightward and drives the tooth plate 510 to move rightward, the tooth plate 510 moves rightward and drives the first gear 511 to rotate, the first gear 511 rotates and drives the rotating rod 509 to rotate, the rotating rod 509 rotates and drives the cooling fan 512 and the plurality of knocking rods 604 to rotate in turn; When the rotating rod 509 rotates to drive the cooling fan 512 to rotate, the rotation of the cooling fan 512 can accelerate air convection, so that the hot air inside the cabinet 1 can be discharged through the cooling port more quickly, thereby preventing the components from being damaged due to overheating; When the rotating rod 509 rotates and drives the knocking rods 604 to rotate, the rotating rod 509 rotates at a smaller angle due to the wind force, and the knocking rods 604 cannot knock the gong 603, thereby avoiding repeated alarm prompts when the wind blows; When the right side of the distribution cabinet is blown by wind, the working process is as above.
