[0002] With the development of the power system, the safety and reliability of distribution cabinets / boxes are crucial. Traditional distribution boxes have deficiencies in aspects such as fire prevention, water prevention, dust prevention, and fire extinguishing. For example, the existing distribution cabinets only perform waterproof treatment at the bottom wiring ports, and only apply fireproof coatings on the external cables of the wiring ports, without other fire prevention treatments. The fireproof coatings on the external cables may become ineffective when in the underground environment for a long time. Therefore, once a fire breaks out inside the distribution cabinet, it will burn along the cables to the outside, causing secondary damage. In addition, the existing distribution cabinets are equipped with fire alarm devices, but lack actual fire extinguishing devices, and the emergency handling ability is poor. To meet the actual needs and ensure safety, the utility model provides a three-proof type distribution cabinet with functions of fire prevention, water prevention, dust prevention, and automatic fire extinguishing.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0016] Such as Figure 1-2As shown in the figure, a three-proof power distribution cabinet includes a cabinet body 1, a fire extinguishing device 5, a dust-proof sponge 3, a fire-blocking module 7, and an intumescent fireproof sealant 8. A plurality of wiring ports 12 for accessing cables 6 are provided at the bottom of the cabinet body 1. The fire-blocking module 7 is provided with a through hole 13 matching the overall outer diameter of the cable 6. The fire-blocking module 7 is arranged at the position of the wiring port 12 at the bottom of the cabinet body 1. The cable 6 passes through the wiring port 12 and the through hole 13. The intumescent fireproof sealant 8 is arranged at the gaps between the wiring port 12, the through port, and the cable 6. A ventilation port 2 is opened on the side wall of the cabinet body 1, and a dust-proof sponge 3 is arranged in the ventilation port 2. The fire extinguishing device 5 is arranged on the inner wall of the cabinet body 1 for extinguishing fire inside the cabinet body 1. A magnetic suction cup 4 is arranged on the side wall of the fire extinguishing device 5 and is connected to the side wall of the cabinet body 1 through the magnetic suction cup 4. A dust-proof net 9 is arranged outside the ventilation port 2. A sealing strip 10 is arranged at the door of the cabinet body 1. A fireproof coating 11 is arranged on the cable 6 corresponding to the outside of the wiring port 12.

[0017] The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, which are as follows:

[0018] The fire extinguishing device 5 adopts the prior art, the invention patent with the application number of 202210782230.2; the fire-blocking module 7 is the prior art. The fire-blocking module 7 refers to a solid made of fireproof materials with a certain shape and size specification, and is installed by 360-degree natural bite. The intumescent fireproof sealant 8 is an environment-friendly one-component water-based sealant. After curing, it has a certain elasticity, will not crack or powder after long-term use, and its expanded volume can reach about 5 times the original volume.

[0019] According to the attached Figure 1-2 As can be seen from the description, when the present utility model is in use, a ventilation port 2 is opened on the side wall of the cabinet body 1, and a dust-proof sponge 3 is arranged in the ventilation port 2. The dust-proof sponge 3 still has a ventilation effect and can block external dust from entering the inside of the cabinet body 1. When the power distribution cabinet catches fire and reaches a certain temperature, the fire extinguishing device 5 can automatically extinguish the fire inside the power distribution cabinet. For details, reference can be made to the invention patent with the application number of 202210782230.2.

[0020] During installation, fire and water protection is also provided between the cable 6 and the bottom of the cabinet 1. Clean the wiring port 12 and the cable 6 to be penetrated to make them dry, free of dust and debris. Measure the size of the wiring port 12 and the overall shape and approximate size of the cable 6. Cut the firestop module 7 according to the shape and size of the cable 6 to make a through hole 13. Pass the cable 6 through the through hole 13 of the wiring port 12 and the firestop module 7, and insert the firestop module 7 into the gap of the wiring port 12. Also, set the firestop module 7 at the positions corresponding to the wiring port 12 inside and outside the bottom of the cabinet 1, and use the intumescent fireproof sealant 8 to spray and seal all the gaps at the wiring port 12. The firestop module 7 and the intumescent fireproof sealant 8 itself have the function of waterproofing. Here, the fireproofing is mainly described in detail. Once a fire breaks out inside the cabinet 1, the firestop module 7 ensures the effectiveness of the fire compartment, prevents the spread of the fire, and isolates the cables 6 inside and outside the cabinet 1. When the intumescent fireproof sealant 8 is burned, it expands rapidly and effectively seals the gaps left by the combustion of combustibles in the fire, further isolating the cables 6 inside and outside the cabinet 1.

[0021] Among them, a magnetic chuck 4 is provided on the side wall of the fire extinguishing device 5, and it is connected to the side wall of the cabinet 1 through the magnetic chuck 4. The fire extinguishing device 5 can be conveniently installed and disassembled through the magnetic chuck 4, and the fire extinguishing device 5 can be placed adaptively according to the space layout of the power distribution cabinet.

[0022] Among them, a dust-proof net 9 is provided outside the ventilation opening 2 to effectively protect the dust-proof sponge 3 and prevent large impurities outside the cabinet 1 from entering the ventilation opening 2.

[0023] Among them, a sealing strip 10 is provided at the door of the cabinet 1 to ensure that rainwater does not enter.

[0024] Among them, a fireproof coating 11 is provided on the cable 6 corresponding to the outside of the wiring port 12 to further improve the fireproof effect of the cable 6.

[0025] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
