[0002] The intelligent explosion-proof monitoring distribution box is a new type of electrical equipment that integrates explosion-proof design, intelligent sensing, remote monitoring and automatic protection functions. It is widely used in high-risk industrial sites such as petroleum, chemical, natural gas, and coal mines where flammable and explosive gases or dust may exist.

[0003] Chinese Patent CN109193409B, published on August 31, 2021, discloses an explosion-proof intelligent monitoring gas concentration distribution box, which includes a first protective box, a first sealing plate, a sub-circuit breaker, a main circuit breaker, an indicator light, a gas sensor, a PLC, a storage battery, a lifting handle, a second protective box, a second sealing plate, a terminal block, a wiring head, an exhaust head, a line collection and fixing protective pipe structure, a storage and mobile trolley structure, a gas emission installation pipe structure, and a protective installation outer casing structure. The sub-circuit breaker, the main circuit breaker, and the indicator light are respectively embedded inside the first sealing plate.

[0004] The aforementioned application document describes a system that uses a fixed protective conduit structure for collecting and securing the line, which allows the line to be easily secured within connectors, hoses, and bends. This system facilitates the use of the line collection and securing protective conduit structure. However, in the event of an accidental fire inside the main body of the distribution box, it is difficult to mitigate the fire to a certain extent, thus affecting the usability of the device. Summary of the Invention

By configuring the vibration assembly, the two vibration plates can vibrate sequentially, re-energizing the dry powder extinguishing agent that has fallen to that location, improving the utilization rate of the dry powder extinguishing agent, and thus further improving the fire extinguishing efficiency of the device.

[0010] Preferably, the elastic telescopic block is located on the side of the cam and is in contact with the cam.

[0011] Preferably, the second transmission rod is located on the side of the first transmission rod and is in contact with the second transmission rod.

A rotating shaft is rotatably connected to the side of the distribution box outer casing, and a limiting groove is formed at the top of the rotating shaft. A limiting block is connected to the side of the distribution box outer casing via an elastic telescopic block, and a rotating plate is fixedly connected to the outer side of the rotating shaft. By configuring the rotating assembly, an opening can be created during fire suppression, facilitating further fire control by personnel.

[0013] Preferably, the cross-sectional shape of the limiting block is adapted to the cross-sectional shape of the limiting groove.

[0014] Preferably, the rotating plate is located on the side of the arc-shaped rod and is in contact with the arc-shaped rod.

[0015] The advantages of this application are: (1) When the main body of the intelligent explosion-proof monitoring distribution box catches fire, the servo motor and dry powder extinguishing agent placement box can be activated. With the help of the power rod, screw, hose, sliding seat, hard pipe, pipe joint, gear and rack, the dry powder extinguishing agent can be sprayed out through the output head, thereby increasing the coverage area of ​​the dry powder extinguishing agent on the main body of the distribution box and thus improving the fire extinguishing efficiency of the device.

[0016] (2) When the screw is in the rotating state, the intelligent explosion-proof monitoring distribution box can drive the cam fixedly connected to it to rotate. With the cooperation of elastic telescopic block one, transmission rod one, elastic telescopic block two, transmission plate and transmission rod two, the two vibrating plates can vibrate in sequence, which will shake up the dry powder extinguishing agent that has fallen to that place, improve the utilization rate of dry powder extinguishing agent, and thus further improve the fire extinguishing efficiency of the device.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] Example 1, please refer to Figures 1-5 An intelligent explosion-proof monitoring distribution box includes a distribution box shell 100. Inside the distribution box shell 100, a distribution box main body 200 and an intelligent detection module 300 with PLC function are respectively installed. A dry powder extinguishing agent storage box 400 is installed on the top of the distribution box shell 100, and a power rod 500 powered by a servo motor is installed on the side of the distribution box shell 100. When the intelligent detection module 300 with PLC function detects that the distribution box main body 200 is on fire, the servo motor and the dry powder extinguishing agent storage box 400 can be activated, and the servo motor drives the power rod 500 to rotate. A lead screw 601 is fixedly connected to the side of the power rod 500. When the power rod 500 rotates, it can drive the lead screw 601 fixedly connected to it to rotate.

[0027] The distribution box housing 100 has a sliding seat 603 inside, which is mounted on the outer side of the lead screw 601 and connected to the lead screw 601 by a thread. When the lead screw 601 rotates, it can drive the sliding seat 603 to move in the horizontal direction.

[0028] A rigid pipe 604 is mounted at the bottom of the sliding seat 603. A pipe joint 605 is rotatably connected to the side of the rigid pipe 604. A transmission component for transmission is mounted between the lead screw 601 and the pipe joint 605. The transmission component includes a flexible hose 602 mounted on the side of the dry powder extinguishing agent storage box 400. The flexible hose 602 is mounted on the top of the rigid pipe 604 and communicates with the rigid pipe 604. A gear 606 is fixedly connected to the outside of the pipe joint 605. When the sliding seat 603 moves in the horizontal direction, it can drive the rigid pipe 604, the pipe joint 605, and the gear 606 to move synchronously.

[0029] The distribution box housing 100 is internally equipped with a rack 607, which meshes with a gear 606. An output head 608 is mounted on the side of the pipe connector 605. When the gear 606 moves horizontally, it is restricted by the meshing rack 607, causing it to rotate synchronously. The rotating gear 606 drives the pipe connector 605, which is fixedly connected to it, to rotate. This, in turn, causes the pipe connector 605 to rotate the output head 608 mounted on its side, discharging the dry powder extinguishing agent from the dry powder extinguishing agent storage box 400 through the hose 602, rigid pipe 604, pipe connector 605, and output head 608. This increases the coverage area of ​​the dry powder extinguishing agent on the distribution box body 200, thereby improving the fire extinguishing efficiency of the device.

[0030] In use, when the intelligent detection module 300 with PLC function detects a fire in the main body 200 of the distribution box, it can activate the servo motor and the dry powder extinguishing agent storage box 400. The servo motor drives the power rod 500 to rotate, and the rotating power rod 500 drives the lead screw 601 fixedly connected to it to rotate. The sliding seat 603, which is threaded onto the outside of the lead screw 601, is simultaneously restricted by the distribution box housing 100 slidably connected to it, so that the sliding seat 603 moves horizontally during the rotation of the lead screw 601. The sliding seat 603 can drive the rigid pipe 604, pipe joint 605 and gear 606 to move synchronously. While the gear 606 moves horizontally, it is restricted by the gear 607 that meshes with it, so that the gear 606 rotates synchronously when it moves. The rotating gear 606 can drive the pipe joint 605 that is fixedly connected to it to rotate, so that the pipe joint 605 drives the output head 608 mounted on its side to rotate, so that the dry powder extinguishing agent in the dry powder extinguishing agent storage box 400 is sprayed out through the hose 602, rigid pipe 604, pipe joint 605 and output head 608.

[0031] Example 2, please refer to Figures 1-6 Based on Embodiment 1, a vibration assembly 800 is installed inside the distribution box housing 100. The vibration assembly 800 includes a cam 801 fixed to the side of the lead screw 601. When the lead screw 601 is rotating, it can drive the cam 801 fixedly connected to it to rotate.

[0032] A transmission rod 803 is connected to the side of the distribution box housing 100 via an elastic telescopic block 802. The transmission rod 803 is located on the side of the cam 801 and is in contact with the cam 801. When the protruding part of the cam 801 rotates to the position of the transmission rod 803, the protruding part of the cam 801 can squeeze the transmission rod 803, causing the transmission rod 803 to compress the elastic telescopic block 802 and move a certain distance.

[0033] The bottom of the distribution box housing 100 is connected to a transmission plate 805 via an elastic telescopic block 804. A transmission rod 806 is fixedly connected to the side of the transmission plate 805. The transmission rod 806 is located to the side of the transmission rod 803 and is in contact with the transmission rod 803. When the transmission rod 803 moves, it compresses the transmission rod 806. The compressed transmission rod 806 then drives the transmission plate 805, which is fixedly connected to it, to move. At this time, the transmission plate 805 stretches the elastic telescopic block 804 and moves downward a certain distance.

[0034] A vibrating plate 807 is fixedly connected to the top of the transmission plate 805. When the transmission plate 805 moves downward, it causes the vibrating plate 807, which has a certain elasticity, to deform. As the lead screw 601 and cam 801 continue to rotate, the protruding part of cam 801 moves away from the transmission rod 803, and the transmission rod 803 loses its restraint and can be reset under the action of the elastic telescopic block 802. Similarly, the transmission rod 806 and transmission plate 805 lose their restraint and can be reset under the action of the elastic telescopic block 804. This allows the vibrating plate 807 to be reset, re-vibrating the dry powder extinguishing agent that has fallen to that location, improving the utilization rate of the dry powder extinguishing agent, and thus further improving the fire extinguishing efficiency of the device.

[0035] In use, based on Embodiment 1, when the lead screw 601 is rotating, it drives the cam 801 fixedly connected to it to rotate. When the protruding part of the cam 801 rotates to the transmission rod 803, the protruding part of the cam 801 can squeeze the transmission rod 803, causing the transmission rod 803 to compress the elastic telescopic block 802 and move a certain distance. The moving transmission rod 803 can squeeze the transmission rod 806, and the squeezed transmission rod 806 can drive the transmission plate 805 fixedly connected to it to move. At this time, the transmission plate 805 stretches and expands elastically. Block 2 804 moves downward a certain distance, and the transmission plate 805, which is in a downward moving state, can drive the vibrating plate 807, which has a certain elasticity, to deform. As the lead screw 601 and cam 801 continue to rotate, the protruding part of cam 801 moves away from transmission rod 1 803, and transmission rod 1 803 loses its restriction and can be reset under the action of elastic telescopic block 1 802. Similarly, transmission rod 2 806 and transmission plate 805 lose their restriction and can be reset under the action of elastic telescopic block 2 804, thereby enabling the vibrating plate 807 to complete its reset and re-vibrate the dry powder extinguishing agent that has fallen to that location.

[0036] Example 3, please refer to Figures 1-8Based on Embodiments 1 and 2, a rotating assembly 700 is mounted on the side of the distribution box housing 100. The rotating assembly 700 includes a hydraulic chamber 701 that is mounted inside and passes through the distribution box housing 100. One end of the hydraulic chamber 701 is slidably connected to a force-bearing rod 702 via a piston. When the sliding seat 603 moves to the left side, the moving sliding seat 603 can press the force-bearing rod 702, and the pressed force-bearing rod 702 can move to the side.

[0037] The other end of the hydraulic chamber 701 is slidably connected to an arc-shaped rod 703 via a piston. When the force-bearing rod 702 moves to the side, it engages with the hydraulic chamber 701, which is slidably connected to the force-bearing rod 702 via a piston. As the force-bearing rod 702 moves into the hydraulic chamber 701, it compresses the oil originally stored in the hydraulic chamber 701. The oil in the hydraulic chamber 701 is compressed and flows towards the side closer to the arc-shaped rod 703, causing the arc-shaped rod 703, which is slidably connected to the hydraulic chamber 701 via a piston, to move out of the hydraulic chamber 701.

[0038] A rotating shaft 704 is rotatably connected to the side of the distribution box housing 100. A limiting groove 705 is provided on the top of the rotating shaft 704. A limiting block 707 is connected to the side of the distribution box housing 100 via an elastic telescopic block 706. The cross-sectional shape of the limiting block 707 is adapted to the cross-sectional shape of the limiting groove 705. A rotating plate 708 is fixedly connected to the outside of the rotating shaft 704. The rotating plate 708 is located on the side of the arc-shaped rod 703 and is in contact with the arc-shaped rod 703. When the arc-shaped rod 703 is moved out of the hydraulic chamber 701, the rotating plate 708 and the rotating shaft 704 can be rotated by squeezing the rotating plate 708. The limiting groove 705 on the rotating shaft 704 can rotate with the rotating shaft 704 to the bottom position of the limiting block 707. At this time, the limiting block 707 loses its restriction and can move into the limiting groove 705 under the action of the elastic telescopic block 706, restricting the rotating plate 708 and the rotating shaft 704 to the open state. This creates an opening in the process of mitigating the fire, making it easier for staff to further address the situation.

[0039] In use, based on Embodiments 1 and 2, when the sliding seat 603 moves to the left position, the moving sliding seat 603 can compress the force-bearing rod 702. The compressed force-bearing rod 702 can then move to the side. In conjunction with the hydraulic chamber 701, which is slidably connected to the force-bearing rod 702 via a piston, the force-bearing rod 702, as it moves into the hydraulic chamber 701, compresses the oil originally stored in the hydraulic chamber 701. The oil in the hydraulic chamber 701, under compression, flows towards the side closer to the arc-shaped rod 703, driving... An arc-shaped rod 703, which is slidably connected to the hydraulic chamber 701 via a piston, moves out of the hydraulic chamber 701. The moving arc-shaped rod 703 can then rotate the rotating plate 708 and the rotating shaft 704 by pressing the rotating plate 708. The limiting groove 705 on the rotating shaft 704 can then rotate to the bottom position of the limiting block 707. At this time, the limiting block 707 loses its restriction and can move into the limiting groove 705 under the action of the elastic telescopic block 706, thus restricting the rotating plate 708 and the rotating shaft 704 to the open state.
