Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, specifically to a self-propelled explosion-proof high-voltage power distribution cabinet for mining. Background Technology

[0002] A design for a self-contained explosion-proof high-voltage distribution cabinet for mining is presented to ensure a safe, stable, and efficient power supply in high-risk environments such as mines. This design aims to improve the safety and reliability of mine power systems and provide miners with a safe working environment.

[0003] According to the publicly disclosed high-voltage distribution cabinet (publication number: CN 212435097 U), it includes a cabinet body with a door on the front. Inside the cabinet body are two screw rods, with their ends fixedly connected to the bottom and top plates of the cabinet body, respectively. Between the two screw rods are multiple mounting plates, each with multiple through-holes. One side of each mounting plate faces the door. Sleeves are fixedly connected to the left and right ends of each mounting plate, and these sleeves fit over the screw rods. A nut is threaded onto the screw rod at the lower end of each sleeve, and the nut has a size larger than the inner diameter of the sleeve.

[0004] Underground electrical distribution cabinets are typically located underground, where gases, dust, and other substances may be present. These substances can affect the operation of the distribution cabinets, making them unable to withstand external impacts and environmental influences, potentially leading to explosions or other dangerous situations. Even with the aforementioned coordination between components such as screws and bushings, it is difficult to reduce the amount of dust and impurities falling onto the top of the distribution cabinet, prevent the intrusion of external substances, reduce the possibility of fires or explosions, and minimize the risk of explosions due to overheating. These issues require improvement. Utility Model Content

[0008] Furthermore, the power distribution cabinet is located on the displacement trajectory of the protective cover. There are two connecting blocks, which are symmetrical to each other along the vertical central axis of the rotating rod. When the protective cover rotates, it will block the top of the power distribution cabinet to protect it and reduce the entry of dust and impurities into the interior of the power distribution cabinet.

[0009] Furthermore, the distribution cabinet is equipped with buttons on its side, an adjustment rod on its side, and a start button on its side. The button design facilitates the operation of the distribution cabinet by staff.

[0010] Furthermore, the support plate and protective cover are made of metal, and a telescopic column is fixedly connected to the side of the power distribution cabinet. The telescopic end of the telescopic column is fixedly connected to the side of the protective cover. The telescopic column is used to further support the protective cover and ensure smooth operation of the protective cover.

[0011] Furthermore, the side of the distribution cabinet is equipped with a sealing explosion-proof device, which includes a ventilation box. The side of the ventilation box extends through the side of the distribution cabinet, and ventilation openings are provided on the inner wall of the ventilation box. A cover plate is slidably connected to the side of the ventilation box. A thin rod is fixedly connected to the side of the rack, and a pressing block is fixedly connected to the side of the thin rod. A triangular block is fixedly connected to the top of the cover plate. A rectangular plate is fixedly connected to the side of the distribution cabinet, and a rotating shaft is rotatably connected to the side of the rectangular plate. An inclined plate is fixedly connected to the circumference of the rotating shaft, and a second spring is fixedly connected to the side of the inclined plate. A trigger rod is fixedly connected to the side of the cover plate, and a vibration rod is fixedly connected to the top of the inclined plate.

[0016] The working principle and beneficial effects of this utility model are as follows:

[0017] 1. In this utility model, through the cooperation of components such as the electric telescopic rod, protective cover, rack, and rotating rod inside the explosion-proof protection device, the protective cover rotates to the top of the distribution cabinet when it rotates forward. The protective cover automatically rotates to the top of the distribution cabinet, blocking the top of the distribution cabinet and reducing the amount of dust and impurities falling from the mine onto the top of the distribution cabinet. The protective cover can effectively block dust and impurities from the mine, reducing their fall onto the top of the distribution cabinet, thereby reducing the risk of pollution and malfunction. This is crucial for the normal operation of high-voltage power distribution equipment, because dust can lead to a decrease in insulation performance and overheating of the equipment. It can reduce the possibility of explosion due to overheating, thus providing explosion protection, preventing the intrusion of external substances, reducing the possibility of fire or explosion, and ensuring the safety of equipment and personnel.

[0018] 2. In this utility model, through the cooperation of components such as the ventilation box, extrusion block, triangular block, and spring inside the sealed explosion-proof equipment, the air outlet of the ventilation box is blocked, and the distribution cabinet is completely sealed to prevent dust from entering. Vibration shakes the dust off the surface of the ventilation box, reducing the possibility of dust entering the distribution cabinet. Through the sealing design of the cover, the distribution cabinet can effectively prevent dust from entering. The combination of sealing design and dustproof function can reduce electrical sparks caused by dust accumulation, thereby reducing the risk of explosion. It also prevents external dust from entering the distribution cabinet and ensures that the environment inside the cabinet is dry and clean, reducing the risk of short circuits or electrical faults caused by dust accumulation and reducing the danger caused by gas or dust explosions, thereby reducing the possibility of explosion.

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0027] Example 1

[0028] like Figures 1-3 As shown, this embodiment proposes a self-propelled explosion-proof high-voltage distribution cabinet for mining, including a distribution cabinet 1, a switch 2 on the side of the distribution cabinet 1, and an explosion-proof enclosure protection device 3 on the side of the distribution cabinet 1. The explosion-proof enclosure protection device 3 includes a support plate 31, the side of the support plate 31 is fixedly connected to the side of the distribution cabinet 1, one end of the support plate 31 is fixedly connected to an electric telescopic rod 32, a support plate 33 is fixedly connected to the side of the distribution cabinet 1, a rack 34 is slidably connected to the top of the support plate 33, a crossbar 35 is fixedly connected to the side of the distribution cabinet 1, a rotating rod 36 is rotatably connected to the top of the crossbar 35, a gear 37 is fixedly connected to one end of the rotating rod 36, a connecting block 38 is fixedly connected to one end of the rotating rod 36, and a protective cover 39 is fixedly connected to one end of the connecting block 38.

[0029] The rack 34 and gear 37 mesh with each other. The protective cover 39 is located on the top of the distribution cabinet 1. The support plate 31 is made of metal. The rack 34 and gear 37 mesh with each other. The gear 37 will only rotate when the rack 34 moves.

[0030] The distribution cabinet 1 is located on the displacement trajectory of the protective cover 39. There are two connecting blocks 38, which are symmetrical to each other along the vertical central axis of the rotating rod 36. The distribution cabinet 1 is located on the displacement trajectory of the protective cover 39. When the protective cover 39 rotates, it will block the top of the distribution cabinet 1 for protection and reduce the entry of dust and impurities into the interior of the distribution cabinet 1.

[0031] A button 5 is provided on the side of the power distribution cabinet 1, an adjustment rod 6 is provided on the side of the power distribution cabinet 1, and a start button is provided on the side of the electric telescopic rod 32. The design of the button 5 makes it convenient for staff to operate the power distribution cabinet 1.

[0032] The support plate 33 and the protective cover 39 are made of metal. The side of the distribution cabinet 1 is fixedly connected to the telescopic column 310. The telescopic end of the telescopic column 310 is fixedly connected to the side of the protective cover 39. The telescopic column 310 is used to further support the protective cover 39 and ensure that the protective cover 39 operates smoothly.

[0033] In this embodiment, the underground power distribution cabinet 1 is generally located underground. Underground environments may contain gases, dust, and other substances that affect the use of the power distribution cabinet 1, causing it to be unable to withstand external impacts and environmental influences, potentially leading to explosions or other dangerous situations. In this case, the electric telescopic rod 32 can be extended. The extension of the electric telescopic rod 32 will drive the rack 34 to extend. The rack 34 and gear 37 mesh with each other, with the gear 37 positioned on the movement trajectory of the rack 34. When the rack 34 extends, it will drive the gear 37 to rotate clockwise. The clockwise rotation of the gear 37 will drive the rotating rod 36 to rotate. The rotation of the rotating rod 36 will drive the two connecting blocks 38, and the rotation of the connecting blocks 38 will drive the protective cover 39 to rotate. When the gear 37 rotates clockwise, it will drive the protective cover 39 to rotate. As the power distribution cabinet 1 rotates forward, it is positioned on the trajectory of the protective cover 39. The protective cover 39 rotates forward and moves towards the top of the power distribution cabinet 1, automatically blocking the top of the cabinet and reducing the amount of dust and impurities falling from the mine onto its top. The protective cover 39 effectively blocks dust and impurities from the mine, reducing their accumulation on the top of the cabinet and thus lowering the risk of pollution and malfunction. This is crucial for the normal operation of high-voltage power distribution equipment, as dust can cause insulation degradation and overheating. Reducing the risk of explosion due to overheating provides explosion protection, preventing the intrusion of external substances, lowering the possibility of fire or explosion, and ensuring the safety of equipment and personnel.

[0034] Example 2

[0035] like Figures 3-5As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes another embodiment. A sealing explosion-proof device 4 is provided on the side of the distribution cabinet 1. The sealing explosion-proof device 4 includes a ventilation box 41, the side of which extends through the side of the distribution cabinet 1. A ventilation opening 414 is provided on the inner wall of the ventilation box 41. A cover plate 44 is slidably connected to the side of the ventilation box 41. A thin rod 42 is fixedly connected to the side of the rack 34. A pressing block 43 is fixedly connected to the side of the thin rod 42. A triangular block 4 is fixedly connected to the top of the cover plate 44. 7. A rectangular plate 48 is fixedly connected to the side of the distribution cabinet 1. A rotating shaft 49 is rotatably connected to the side of the rectangular plate 48. An inclined plate 410 is fixedly connected to the circumference of the rotating shaft 49. A spring 411 is fixedly connected to the side of the inclined plate 410. An actuating rod 413 is fixedly connected to the side of the cover plate 44. A vibrating rod 412 is fixedly connected to the top of the inclined plate 410. When the distribution cabinet 1 is blocked by the protective cover 39, the ventilation box 41 on the distribution cabinet 1 is automatically covered, sealing the distribution cabinet 1 and reducing the entry of dust into the distribution cabinet 1.

[0036] Triangular block 47 is located on the displacement trajectory of extrusion block 43, ventilation box 41 is located on the displacement trajectory of vibration rod 412, inclined plate 410 is located on the displacement trajectory of trigger rod 413, and triangular block 47 is located on the displacement trajectory of extrusion block 43. When extrusion block 43 moves, it will extrude triangular block 47.

[0037] A short plate 45 is fixedly connected to the side of the ventilation box 41, and a spring 46 is fixedly connected to the top of the short plate 45. The end of the spring 46 away from the short plate 45 is fixedly connected to the side of the cover plate 44. The design of the spring 46 is conducive to the automatic reset of the cover plate 44 when it is not squeezed.

[0038] There are two short plates 45 and springs 46, which are symmetrical to each other along the vertical central axis of the ventilation box 41. The vibrating rod 412 is made of plastic and has two short plates 45 and springs 46, which helps to stably and automatically reset the cover plate 44 and reduce instability during operation.

[0039] Several ventilation openings 414 are provided and are arranged in a linear array on the inner wall of the ventilation box 41. The pressing block 43 has an inclined surface on the side near the triangular block 47. The inclined surface of the pressing block 43 facilitates pressing the triangular block 47 downward, causing the triangular block 47 to move downward.

[0040] In this embodiment, the movement of the rack 34 causes the thin rod 42 and the pressing block 43 to move. The triangular block 47 is located on the movement trajectory of the pressing block 43. When the pressing block 43 moves, it will press against the triangular block 47. The pressing block 43 is provided with an inclined surface, which corresponds to the inclined surface on the triangular block 47. Due to the influence of the inclined surface, the movement of the pressing block 43 will press the triangular block 47 downward. The downward movement of the triangular block 47 will cause the cover plate 44 to move downward. The side of the cover plate 44 is slidably connected to the side of the ventilation box 41. The downward movement of the cover plate 44 will cause the cover plate 44 to move downward. This will block the air outlet of the ventilation box 41, completely sealing the distribution cabinet 1 to prevent dust from entering and ensuring the dryness inside the distribution cabinet 1. When the cover plate 44 moves downward, it will also drive the trigger rod 413 downward. The downward movement of the trigger rod 413 will press against the inclined plate 410. The inclined plate 410, under pressure, will move towards the side closer to the rectangular plate 48 and press against the second spring 411. When ventilation is needed, opening the cover plate 44 will cause it to move upward, which will then drive the trigger rod 413. Moving upwards, the trigger rod 413 will no longer press the inclined plate 410, and the inclined plate 410 will no longer press the second spring 411. The elastic force of the second spring 411 will cause the inclined plate 410 to spring back. The springback of the inclined plate 410 will drive the vibrating rod 412 to move. The ventilation box 41 is located on the movement trajectory of the vibrating rod 412. The movement of the vibrating rod 412 will strike the ventilation box 41. At this time, the ventilation box 41 is in the state of having just opened the cover 44, and there may be dust on the surface. The presence of dust may accidentally enter the ventilation box 41. Vibration will cause the ventilation box 41 to... The vibration of surface dust reduces the possibility of dust entering the distribution cabinet 1, thereby reducing the possibility of explosion. Through the sealing design of cover plate 44, the distribution cabinet 1 can effectively prevent dust from entering. The combination of sealing design and dustproof function can reduce electrical sparks caused by dust accumulation, thereby reducing the risk of explosion. Preventing external dust from entering the distribution cabinet 1 also ensures that the environment inside the cabinet is dry and clean, reducing the risk of short circuits or electrical faults caused by dust accumulation, and reducing the danger caused by gas or dust explosion, thereby reducing the possibility of explosion.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
