Description

Technical Field

[0001] This utility model relates to the field of electrical distribution box technology, and in particular to an indoor fireproof electrical distribution box. Background Technology

[0002] In modern building electrical systems, distribution boxes, as key equipment for power distribution and control, are widely used in various indoor locations such as residential buildings, commercial buildings, industrial plants, and public facilities. Their function is to receive electrical energy from the upstream power source and distribute it to various electrical devices, while also protecting, controlling, and monitoring the circuits. However, during operation, distribution boxes pose a fire risk due to overheating, overload, and short circuits caused by electrical components. Once a distribution box catches fire, it not only leads to power outages, disrupting normal production and daily life, but may also trigger a wider fire, causing severe property damage and casualties.

[0003] Traditional indoor electrical distribution boxes have many shortcomings in terms of fire resistance. Many distribution boxes only use ordinary metal or plastic shells. These materials cannot effectively prevent the spread of fire when a fire occurs. They are easily melted or burned by high temperatures, thus accelerating the development of the fire. Even if some distribution boxes are equipped with simple fire extinguishing devices, such as dry powder fire extinguishers or fire extinguishing bombs, these devices often require manual operation and are difficult to achieve rapid automatic response in the early stages of a fire, making it impossible to control the fire in a timely and effective manner.

[0008] The fire extinguishing assembly includes a fixed base, the lower end of which is fixedly connected to the top of the fireproof electrical box, and a gas storage tank is fixedly connected to the surface of the fixed base. The gas storage tank stores fire extinguishing gas inside, and a gas supply pipe is fixedly connected to the surface of the gas storage tank.

[0010] In a preferred embodiment of the indoor fireproof electrical distribution box of this utility model, the fire extinguishing pipe has an "S" shaped cross-section and is located inside the fireproof electrical box.

[0011] In a preferred embodiment of the indoor fireproof distribution box of this utility model, the switch assembly includes a sealing cylinder, which is connected to a gas supply pipe. A sealing plug is slidably connected to the inner wall of the sealing cylinder.

A sealing frame is sleeved on the outer side of the sealing plate, and one side of the sealing frame is fixedly connected to the inner wall of the fireproof distribution box.

[0012] In a preferred embodiment of the indoor fireproof electrical distribution box of this utility model, the surface of the traction rope is respectively wound with fixed pulley A and fixed pulley B, and both fixed pulley A and fixed pulley B are rotatably connected to the inner wall of the fireproof electrical box.

[0016] (III) Beneficial Effects

[0017] This utility model provides an indoor fireproof electrical distribution box. It has the following beneficial effects:

[0018] 1. By storing fire extinguishing gas in the gas tank, when a fire occurs, opening the switch assembly allows the fire extinguishing gas to be delivered through the gas supply pipe to the fire extinguishing pipe. The gas is then rapidly ejected through multiple exhaust ports on the surface of the fire extinguishing pipe, covering the interior space of the distribution box. Because the fire extinguishing pipe is S-shaped, it can be more widely distributed within the box, allowing for more even distribution of the fire extinguishing gas, quickly and effectively extinguishing the fire source, preventing the spread of fire, and reducing damage to the fireproof electrical box and internal electrical equipment. Simultaneously, a pressure gauge on the top of the gas tank can monitor the pressure of the fire extinguishing gas in real time, allowing for timely replenishment of the gas and ensuring that the gas tank provides sufficient pressure of fire extinguishing gas during a fire, guaranteeing the fire extinguishing effect.

[0019] 2. The photoelectric smoke sensor can detect fire in its early stages. Once a fire is detected, the electromagnetic switch will immediately cut off the power, so that the armature frame is no longer attracted and fixed by the electromagnetic switch. The sealing plate slides into the sealing frame with the help of gravity and guide blocks, thereby sealing the heat dissipation window, enhancing the sealing of the fireproof electrical box, and improving the fire extinguishing efficiency. During the descent of the sealing plate, it will pull the traction rope. Through fixed pulleys A and B, the direction of the traction rope is changed, thereby pulling the sealing plug in the sliding cylinder, so that the extinguishing gas in the gas supply pipe can flow into the extinguishing pipe, quickly extinguishing the fire source from the early stage and preventing the fire from spreading.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Example 1

[0029] Reference Figure 1 , Figure 2 and Figure 3 This is the first embodiment of the present utility model. This embodiment provides an indoor fireproof distribution box, including a fireproof box 1. The front of the fireproof box 1 is hinged with a door 2, and the side wall of the fireproof box 1 is provided with a heat dissipation window 3. The top of the fireproof box 1 is provided with a fire extinguishing component 4.

[0030] The fire extinguishing assembly 4 includes a mounting base 401. The lower end of the mounting base 401 is fixedly connected to the top of the fireproof electrical box 1. A gas storage tank 402 is fixedly connected to the surface of the mounting base 401. The gas storage tank 402 stores fire extinguishing gas inside. A gas supply pipe 405 is fixedly connected to the surface of the gas storage tank 402. A switch assembly 5 is provided on the surface of the gas supply pipe 405. A fire extinguishing pipe 406 is fixedly connected to the other end of the gas supply pipe 405. Multiple exhaust ports 407 are provided on the surface of the fire extinguishing pipe 406.

[0031] Specifically, the surface of the gas storage tank 402 is provided with a gas inlet 403, and a pressure gauge 404 is provided on the top of the gas storage tank 402. The fire extinguishing pipe 406 has an "S" shaped cross section and is located inside the fireproof electrical box 1.

[0032] Furthermore, by storing extinguishing gas in the gas storage tank 402, when a fire occurs, opening the switch assembly 5 allows the extinguishing gas to be delivered through the gas supply pipe 405 to the extinguishing pipe 406. The extinguishing gas is then rapidly ejected through multiple exhaust ports 407 on the surface of the extinguishing pipe 406, covering the interior space of the distribution box. Because the extinguishing pipe 406 is S-shaped, it can be more widely distributed within the box, allowing the extinguishing gas to be more evenly distributed, quickly and effectively extinguishing the fire source, preventing the fire from spreading, and reducing damage to the fireproof electrical box 1 and its internal electrical equipment. Simultaneously, the pressure gauge 404 installed on the top of the gas storage tank 402 can monitor the pressure of the extinguishing gas in the tank in real time, thereby replenishing the extinguishing gas promptly and ensuring that the gas storage tank 402 can provide sufficient pressure of extinguishing gas during a fire, guaranteeing the fire extinguishing effect.

[0033] Example 2

[0034] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The switch assembly 5 includes a sealing cylinder 509, which is connected to the gas supply pipe 405. A sealing plug 508 is slidably connected to the inner wall of the sealing cylinder 509. A traction rope 505 is fixedly connected to one side of the sealing plug 508. A sealing plate 504 is fixedly connected to the other end of the traction rope 505. A sealing frame 501 is sleeved on the outer side of the sealing plate 504. One side of the sealing frame 501 is fixedly connected to the inner wall of the fireproof electrical box 1.

[0035] Specifically, the surface of the traction rope 505 is wound with fixed pulleys A506 and B507 respectively. Fixed pulleys A506 and B507 are rotatably connected to the inner wall of the fireproof electrical box 1. Guide grooves 502 are opened on both sides of the inner wall of the sealing frame 501. Guide blocks 503 are slidably connected to the inner wall of the guide grooves 502. One side of the guide block 503 is fixedly connected to the side wall of the sealing plate 504. An armature frame 511 is fixedly connected to the top of the sealing plate 504. An electromagnetic switch 512 is provided on one side of the armature frame 511. A photoelectric smoke sensor 513 is installed on the top of the electromagnetic switch 512. A spring 510 is provided inside the sliding cylinder. The spring 510 is sleeved on the outside of the traction rope 505.

[0036] Furthermore, the photoelectric smoke sensor 513 can detect the fire in its early stages. Once the fire is detected, the electromagnetic switch 512 will immediately cut off the power, so that the armature frame 511 will no longer be attracted and fixed by the electromagnetic switch 512. The sealing plate 504 will slide into the sealing frame 501 with the help of gravity and the guide block 503, thereby sealing the heat dissipation window 3, enhancing the sealing of the fireproof electrical box 1, and improving the fire extinguishing efficiency. During the descent of the sealing plate 504, it will pull the traction rope 505. The fixed pulleys A506 and B507 will change the direction of the traction rope 505, thereby pulling the sealing plug 508 in the sliding cylinder, so that the fire extinguishing gas in the gas supply pipe 405 can flow into the fire extinguishing pipe 406, quickly extinguishing the fire source from the early stage and preventing the fire from spreading.

[0037] Working principle: During use, the photoelectric smoke sensor 513 can detect the fire in its early stages. Once a fire is detected, the electromagnetic switch 512 will immediately cut off the power, thus preventing the armature frame 511 from being attracted and fixed by the electromagnetic switch 512. The sealing plate 504 slides into the sealing frame 501 by gravity and the guide block 503, thereby sealing the heat dissipation window 3, enhancing the sealing of the fireproof electrical box 1, and improving the fire extinguishing efficiency. During the descent of the sealing plate 504, it will pull the traction rope 505, which, through the fixed pulley A506 and the fixed pulley... B507 changes the direction of the traction rope 505, thereby pulling the sealing plug 508 inside the sliding cylinder. This allows the extinguishing gas in the gas storage pipe to be transported to the extinguishing pipe 406 through the gas delivery pipe 405. The extinguishing gas is then rapidly ejected through multiple exhaust ports 407 on the surface of the extinguishing pipe 406, covering the interior space of the fireproof electrical box 1. Because the extinguishing pipe 406 is S-shaped, it can be more widely distributed inside the box, making the extinguishing gas more evenly distributed, quickly and effectively extinguishing the fire source, preventing the fire from spreading, and reducing the damage to the distribution box and internal electrical equipment caused by the fire.
