Description

Technical Field

[0001] This utility model belongs to the technical field of power distribution box safety monitoring equipment, and particularly relates to a power distribution box safety monitoring equipment. Background Technology

[0002] Distribution box safety monitoring equipment is an intelligent device that integrates sensors, data analysis, and communication technologies. It is designed to monitor the operating status of distribution boxes in real time and prevent electrical fires, equipment failures, and personal safety accidents.

[0003] Currently, existing electrical distribution box safety detection equipment only has detection functions and cannot extinguish the flames burning inside the distribution box in time. When rescuers arrive at the scene, they will miss the best opportunity to put out the fire. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that existing technologies only have monitoring functions but cannot extinguish flames, and therefore propose a safety monitoring device for power distribution boxes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A power distribution box safety monitoring device includes a power distribution box, a monitoring device body fixedly connected to the inner wall of the power distribution box, a control box fixedly connected to the right side of the power distribution box, a controller fixedly connected to the inner wall of the control box, a self-locking motor disposed on the left side of the power distribution box, and the controller electrically connected to the self-locking motor and the monitoring device body respectively via wires. Two fixing plates are fixedly connected to the left side of the power distribution box, and a rotating shaft is rotatably connected to the inner walls of the two fixing plates. The output end of the self-locking motor is fixedly connected to one end of the rotating shaft near the self-locking motor, and a transmission mechanism is fixedly connected to the outer surface of each rotating shaft. The gears have their outer surfaces meshing with each other. A transmission rope is fixedly connected to the outer surface of each shaft. A rectangular plate and a limiting plate are fixedly connected to the upper and lower surfaces of the distribution box. A return spring is fixedly connected to the left side of each rectangular plate. Each return spring is located in the inner cavity of the limiting plate. A baffle is fixedly connected to the left end of each return spring. The left side of each baffle is fixedly connected to the right end of the transmission rope. Several identical first circular heat dissipation holes are opened on the upper surface of each baffle. Several identical second circular heat dissipation holes are opened on the upper and lower surfaces of the distribution box.

[0007] Preferably, the front of the distribution box is hinged to a movable door, and a handle is fixedly connected to the front of the movable door.

[0008] Preferably, a base plate is provided below the self-locking motor, and the front of the base plate is fixedly connected to the back of one of the fixing plates.

[0009] Preferably, two sets of rectangular blocks are fixedly connected to the left side of the distribution box, and a short shaft is rotatably connected to the inner wall of each set of rectangular blocks, and the outer surface of each short shaft is in contact with the outer surface of the transmission rope.

[0010] Preferably, the right side of the control box has two slots, and each slot has a locking block inside.

[0011] Preferably, the right ends of the two card blocks are fixedly connected to a disassembly plate, and the left side of the disassembly plate is in contact with the right side of the control box.

[0012] In summary, the technical effects and advantages of this utility model are as follows: By incorporating a monitoring device body, the working status of the internal wiring of the distribution box can be detected. When a fault occurs in the internal wiring of the distribution box, the monitoring device body can transmit information to the controller via electrical signals. The controller, in turn, controls the self-locking motor to operate via electrical signals. When the self-locking motor operates, it drives one of the shafts to rotate counterclockwise. This shaft transmits power to the other shaft through a transmission gear, causing the two shafts to rotate in different directions. This loosens the transmission ropes fixed to the surfaces of the two shafts, and the return spring pulls the baffle towards the position of the limit plate until the baffle contacts the limit plate. At this point, the first circular heat dissipation hole on the surface of the baffle is offset from the second heat dissipation holes on the upper and lower surfaces of the distribution box, preventing outside air from entering the interior of the distribution box and thus avoiding the problem of the fire inside the distribution box growing larger.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-5 In one embodiment of this utility model, a power distribution box safety monitoring device is provided, including a power distribution box 1, a monitoring device body 12 fixedly connected to the inner wall of the power distribution box 1, a control box 11 fixedly connected to the right side of the power distribution box 1, a controller 21 fixedly connected to the inner wall of the control box 11, a movable door 9 movably hinged to the front of the power distribution box 1, and a handle 10 fixedly connected to the front of the movable door 9. By providing the handle 10, the movable door 9 can be opened by pulling the handle 10, thereby allowing operation of the equipment inside the power distribution box 1.

[0021] Furthermore, in this embodiment of the present invention, a self-locking motor 3 is provided on the left side of the distribution box 1. The controller 21 is electrically connected to the self-locking motor 3 and the monitoring device body 12 respectively through wires. Two fixing plates 2 are fixedly connected to the left side of the distribution box 1. A base plate 14 is provided below the self-locking motor 3. The front of the base plate 14 is fixedly connected to the back of one of the fixing plates 2. By providing the base plate 14, the base plate 14 can provide support for the self-locking motor 3, making the self-locking motor 3 run more stably.

[0022] In addition, the inner walls of the two fixed plates 2 are rotatably connected to a rotating shaft 16. The output end of the self-locking motor 3 is fixedly connected to one of the rotating shafts 16 near the end of the self-locking motor 3. The outer surface of each rotating shaft 16 is fixedly connected to a transmission gear 15. The outer surfaces of the two transmission gears 15 mesh with each other. The outer surface of each rotating shaft 16 is fixedly connected to a transmission rope 4. The left side of the distribution box 1 is fixedly connected to two sets of rectangular blocks 18. The inner wall of each set of rectangular blocks 18 is rotatably connected to a short shaft 17. The outer surface of each short shaft 17 is in contact with the outer surface of the transmission rope 4.

[0023] This invention incorporates a rectangular block 18 and a short shaft 17. The short shaft 17 helps prevent excessive friction between the transmission rope 4 and the equipment during movement, thereby increasing the service life of the transmission rope 4.

[0024] In one implementation of this utility model, a rectangular plate 8 and a limiting plate 7 are fixedly connected to the upper and lower surfaces of the distribution box 1. A reset spring 19 is fixedly connected to the left side of each rectangular plate 8. Each reset spring 19 is disposed in the inner cavity of the limiting plate 7. A baffle 5 is fixedly connected to the left end of each reset spring 19. The right end of the transmission rope 4 is fixedly connected to the left side of each baffle 5. Several identical first circular heat dissipation holes 6 are opened on the upper surface of each baffle 5. Two slots 20 are opened on the right side of the control box 11. A locking block 22 is locked inside each slot 20.

[0025] This utility model, by providing a card slot 20 and a card block 22, utilizes the card block 22 and the card slot 20 to connect external devices to the control box 11, achieving a good auxiliary effect.

[0026] Furthermore, the upper and lower surfaces of the distribution box 1 are provided with several identical second circular heat dissipation holes 13. The right ends of the two locking blocks 22 are fixedly connected to a disassembly plate 23. The left side of the disassembly plate 23 is in contact with the right side of the control box 11. By providing the disassembly plate 23, the distribution box 1 can be protected, and the disassembly plate 23 can be removed when the controller 21 needs to be operated.

[0027] In use, the monitoring device body 12 can be used to detect the working status of the internal circuitry of the distribution box 1. When a fault occurs in the internal circuitry of the distribution box 1, the monitoring device body 12 will use its own alarm function to send an alarm to the outside world. At the same time, the monitoring device body 12 will transmit information to the controller 21 via electrical signals. The controller 21 will also control the operation of the self-locking motor 3 via electrical signals. It should be understood that when the distribution box 1 is not faulty, the self-locking motor 3 can use its self-locking characteristic to keep the two transmission ropes 4 in a taut state for a long time. When the self-locking motor 3 is running, it will drive one of the rotating shafts 16 to rotate counterclockwise. This rotating shaft 16 will transmit power to the other rotating shaft 16 through the transmission gear 15. The two rotating shafts 16 rotate in different directions. It is clear that the rotating shaft 16 fixed to the self-locking motor 3 rotates counterclockwise, while the rotating shaft 16 not fixed to the self-locking motor 3 rotates clockwise. This allows the taut transmission ropes 4 that are fixed to the surfaces of the two rotating shafts 16 to relax. At this time, the transmission ropes 4 are not taut, and the two return springs 19 will pull the baffle 5 to move towards the position of the limit plate 7 until the baffle 5 contacts the limit plate 7. At this time, the first circular heat dissipation hole 6 on the surface of the baffle 5 will be offset from the second circular heat dissipation hole 13 on the upper and lower surfaces of the distribution box 1, preventing outside air from entering the interior of the distribution box 1, thereby avoiding the problem of the fire inside the distribution box 1 growing larger.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
