Description

Technical Field

[0001] This utility model relates to the field of power distribution box technology, and in particular to a fireproof and explosion-proof power distribution box. Background Technology

[0002] In modern industrial production, business operations, and various infrastructure constructions, power distribution boxes serve as key hubs for power distribution and control, and their operational safety and reliability are of paramount importance.

[0003] With the increasing size and complexity of power systems, distribution boxes face numerous potential risks. Electrical faults such as prolonged operation of electrical equipment, aging wiring, overload, and short circuits occur frequently. Once these faults occur, they often generate high temperatures and electrical sparks inside the distribution box, which can easily lead to fires or even explosions, posing a significant threat to the safety of surrounding equipment and personnel. Therefore, we propose a fireproof and explosion-proof power distribution box to address these issues. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a fireproof and explosion-proof power distribution box.

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

[0006] A fireproof and explosion-proof power distribution box includes a distribution box body, a control box mounted on the top of the distribution box body, a canopy mounted on the top of the control box, a fire extinguishing agent tank installed inside the control box, a connecting pipe rotatably mounted on the inner wall of the top of the distribution box body, the top of the connecting pipe extending to the control box, a flexible hose mounted on the connecting pipe, one end of the flexible hose being fixedly connected to the outlet of the fire extinguishing agent tank, and a nozzle mounted on the bottom end of the connecting pipe, and two vertical plates fixedly mounted on the inner wall of the top of the distribution box body, a rotating shaft rotatably mounted on one side of the vertical plates, and a common guide plate fixedly mounted on the ends of the two corresponding rotating shafts that are close to each other.

[0007] Optionally, a smoke sensor and a controller are fixedly installed on the top of the control box, and a solenoid valve is installed at the opening of the fire extinguishing agent tank. The smoke sensor, solenoid valve, and drive motor are all electrically connected to the controller.

[0008] By adopting the above technical solution and by setting up a controller, it is convenient to control the solenoid valve and the drive motor. The controller can intermittently start the drive motor in both forward and reverse directions, thereby realizing the reciprocating rotation of the transmission shaft.

[0009] Optionally, the top of the distribution box body is provided with a groove, and multiple fixing springs are fixedly installed at equal intervals on the bottom inner wall of the groove. The top of the multiple fixing springs is fixedly installed with the same extrusion plate, and a transmission mechanism is provided between the extrusion plate and the rotating shaft.

[0010] By adopting the above technical solution and by setting a fixed spring, when the eccentric wheel does not press the extrusion plate, the fixed spring can push the extrusion plate to reset.

[0011] Optionally, the transmission mechanism includes a rack seat and a rotating gear. The rotating gear is fixedly mounted on a rotating shaft, and multiple rack seats are fixedly mounted on the bottom of the extrusion plate, with the rack seats meshing with the corresponding rotating gears.

[0012] By adopting the above technical solution, and by setting up a rack seat and a rotating gear, the movement of the rack seat can drive the rotating gear to rotate.

[0013] Optionally, the bottom inner wall of the groove is provided with multiple rectangular holes, and the rack seat is slidably connected to the corresponding rectangular holes.

[0014] By adopting the above technical solution and by setting a rectangular hole, the rack seat can be guided, and the rack seat can be moved stably.

[0015] Optionally, a drive motor is fixedly installed inside the control box, a drive mechanism is provided between the drive motor and the extrusion plate, and a linkage mechanism is provided between the drive motor and the connecting pipe. The drive mechanism includes a transmission shaft and an eccentric wheel. The transmission shaft is fixedly installed on the output shaft of the drive motor, and the eccentric wheel is fixedly installed on the transmission shaft, and the eccentric wheel is in contact with the extrusion plate.

[0016] By adopting the above technical solution, and by setting an eccentric wheel, the rotation of the eccentric wheel can squeeze the extrusion plate, thereby achieving the purpose of the extrusion plate moving up and down reciprocatingly.

[0017] Optionally, the linkage mechanism includes a driving bevel gear and a driven bevel gear. The driving bevel gear is fixedly mounted on the transmission shaft, and the driven bevel gear is fixedly mounted on the connecting pipe. The driving bevel gear meshes with the driven bevel gear.

[0018] By adopting the above technical solution, the transmission shaft can drive the connecting pipe to rotate through the cooperation of the driving bevel gear and the driven bevel gear.

[0019] The beneficial effects of this utility model are:

[0020] 1. The smoke sensor can monitor the fire in the distribution box. When an open flame appears inside the distribution box, the smoke sensor can send a signal to the controller. The controller can open the solenoid valve, so that the fire extinguishing agent can spray the fire extinguishing agent into the distribution box through the nozzle, thereby extinguishing the fire.

[0021] 2. At the same time, the controller can intermittently start the drive motor in both forward and reverse directions. The drive motor can drive the connecting pipe and the nozzle to rotate back and forth. Through the cooperation of the transmission shaft, eccentric wheel, fixed spring, extrusion plate and rack seat, the rotation shaft and guide plate can be rotated.

[0022] 3. By reciprocating the rotation of the nozzle and the oscillation of the guide plate, the sprayed extinguishing agent can be guided, thereby achieving comprehensive spraying of extinguishing agent on the distribution box body and avoiding the situation where insufficient fire extinguishing is caused by spray dead spots, which may lead to an explosion.

[0029] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0030] This application discloses a fireproof and explosion-proof power distribution box.

[0032] Specifically, a smoke sensor 501 and a controller 502 are fixedly installed on the top of the control box 2, and a solenoid valve is installed at the opening of the fire extinguishing agent tank 401. Both the smoke sensor 501 and the solenoid valve are electrically connected to the controller 502.

[0033] Specifically, the top of the distribution box body 1 is provided with a groove 701, and multiple fixing springs 702 are fixedly installed at equal intervals on the bottom inner wall of the groove 701. The top of the multiple fixing springs 702 is fixedly installed with the same pressing plate 703. A transmission mechanism is provided between the pressing plate 703 and the rotating shaft 602. The transmission mechanism includes a rack seat 802 and a rotating gear 801. The rotating gear 801 is fixedly installed on the rotating shaft 602. Multiple rack seats 802 are fixedly installed at the bottom of the pressing plate 703, and the rack seats 802 mesh with the corresponding rotating gears 801. The rack seats 802 are slidably connected to the corresponding rectangular holes.

[0034] Specifically, a drive motor 901 is fixedly installed inside the control box 2. A drive mechanism is provided between the drive motor 901 and the extrusion plate 703, and a linkage mechanism is provided between the drive motor 901 and the connecting pipe 403. The drive mechanism includes a transmission shaft 902 and an eccentric wheel 903. The transmission shaft 902 is fixedly installed on the output shaft of the drive motor 901, and the eccentric wheel 903 is fixedly installed on the transmission shaft 902. The eccentric wheel 903 is in contact with the extrusion plate 703. The linkage mechanism includes a drive bevel gear 904 and a driven bevel gear 905.

[0035] The working principle of this utility model is as follows: The smoke sensor 501 can monitor the distribution box body 1 for fire. When an open flame appears inside the distribution box body 1, the smoke sensor 501 sends a signal to the controller 502. The controller 502 then opens the solenoid valve, allowing the fire extinguishing agent tank 401 to spray the fire extinguishing agent into the distribution box body 1 through the nozzle 404, thus extinguishing the fire. Simultaneously, the controller 502 can intermittently start and stop the drive motor 901 in both directions. The drive motor 901 drives the transmission shaft 902 to rotate. Through the engagement of the drive bevel gear 904 and the driven bevel gear 905, the rotation of the transmission shaft 902 drives the connecting pipe 403. The nozzle 404 reciprocates, and the drive shaft 902 rotates through the eccentric wheel 903 to press the extrusion plate 703. The fixed spring 702 can push the extrusion plate 703 to reset, so that the rotation of the eccentric wheel 903 can drive the rack seat 802 to move up and down. The rack seat 802 can drive the rotating shaft 602 and the guide plate 603 to rotate through the rotating gear 801. Through the reciprocating rotation of the nozzle 404 and the reciprocating swing of the guide plate 603, the sprayed fire extinguishing agent can be guided, so as to achieve comprehensive spraying of fire extinguishing agent on the distribution box body 1, which can avoid the situation of insufficient fire extinguishing due to spray dead corners and the possibility of explosion.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
