At present, some people in society think that the roadside distribution cabinet is very safe, and there may be situations where they lean against the distribution cabinet to make a phone call, and children may climb on it. If there is a leakage in the distribution cabinet, it will also endanger life safety. According to some news that have come out, there have been many cases of leakage and fire caused by serious aging of internal components. There are also some distribution boxes with wiring harnesses exposed outside. When it rains, rain may fall on the interface between the wiring harness and the distribution box, resulting in electric shock damage. Therefore, certain improvements are needed.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figures 1 to 5As shown, a power distribution cabinet for electric power engineering includes a cabinet body 1, support legs 2, cabinet door hinges 3, fixing frames 4, connection holes 5, external expansion pipes 6, powder bins 7, sensors 8, delivery pipes 9, nozzles 10, door panels 11, locking devices 12, inspection windows 13, mounting frames 14, equipment tables 15, electrical components 16, canopies 17 and rock wool boards 18. Support legs 2 are provided at the bottom of the cabinet body 1. The cabinet door hinges 3 are fixedly connected to the front right side of the cabinet body 1. The fixing frames 4 are arranged on both sides of the inner wall of the cabinet body 1. The connection holes 5 are opened at the front end of the inner wall of the cabinet body 1. The external expansion pipes 6 are fixedly connected to the outside of the connection holes 5. The powder bins 7 are arranged on the cabinet body 1. 1, the sensor 8 is arranged at the top front end of the powder bin 7, the delivery pipe 9 is arranged at the top rear end of the powder bin 7, the nozzle 10 is arranged on the top of the delivery pipe 9, the cabinet 1 and the door panel 11 are connected through the cabinet door hinge 3, the locking device 12 is arranged on the left side of the front of the door panel 11, the exploration window 13 is arranged above the front of the door panel 11, the mounting frame 14 is connected to the fixing frames 4 on both sides by bolts, the equipment table 15 is arranged on the top of the front of the mounting frame 14, the electrical component 16 is arranged on the bottom of the front of the mounting frame 14, the awning 17 is arranged on the top of the cabinet 1, and the rock wool board 18 is arranged around the inner wall of the cabinet 1.

[0022] refer to Figures 1 to 5 The external expansion pipe 6 is a downward 45-degree inclined pipe, and the bottom pipe opening is cut parallel to the ground.

[0023] As a technical optimization solution of the utility model, by setting the external expansion tube 6 as a downward 45-degree inclined tube, the wiring harness is connected to the interface in the distribution box. Due to time, there may be aging problems in the future. When it rains, it can be completely guaranteed that rainwater will not contact the interface, and the surface of the wiring harness at the interface will not be directly exposed to the sun, thereby extending the service life of the wiring harness.

[0024] refer to Figures 1 to 5 , the powder bin 7 is set to contain dry powder, and other materials cannot be added.

[0025] As a technical optimization solution of the utility model, dry powder is set in the powder bin 7, and other materials cannot be added. This is mainly because dry powder can be used for electrical fires and can be effectively extinguished. After the dry powder is used up, the powder bin 7 can be opened for replenishment.

[0026] refer to Figures 1 to 5 The delivery pipe 9 directly reaches the bottom of the powder bin 7, and the inner circle of the delivery pipe 9 adopts the same siphon pipe as that in the fire extinguisher.

[0027] As a technical optimization solution of the utility model, the inner circle of the delivery pipe 9 adopts a siphon tube consistent with the fire extinguisher, so that the dry powder can be fully sprayed when needed, and the best firefighting opportunity will not be missed due to the inability to spray due to powder accumulation.

[0028] refer to Figures 1 to 5 The rain shelter 17 is not fixedly connected to the cabinet body 1 as a whole, but can be disassembled.

[0029] As a technical optimization solution of the utility model, the canopy 17 and the cabinet body 1 can be disassembled, and normal operation can be performed when the distribution cabinet is inspected, repaired, and the powder bin 7 is replaced and replenished. There is no need for construction workers to squat or bend over for a long time to work like ordinary distribution cabinets because they are relatively small.

[0030] refer to Figures 1 to 5 The surfaces and interiors of the cabinet body 1, the supporting legs 2, the cabinet door hinges 3, the door panels 11, the locking devices 12 and the rain shelter 17 are all uniformly and repeatedly coated with insulating paint.

[0031] As a technical optimization scheme of the utility model, by uniformly and repeatedly applying insulating paint on the surface and interior of the cabinet body 1, supporting legs 2, cabinet door hinges 3, door panels 11, locking devices 12 and awnings 17, rock wool boards 18 are arranged around the inner walls, which can ensure that the surface of the distribution cabinet will not be conductive to the greatest extent possible in the event of leakage. In this way, even if people are leaning on the distribution cabinet at that time, their lives will not be endangered. In the later stage, due to the aging of the rock wool boards 18 over a long period of time, the awning 17 can be directly opened, and the rock wool boards 18 around the inner wall of the cabinet body 1 can be taken out from the top and replaced with new rock wool boards 18.

[0032] The working principle and use process of the utility model are as follows: when in use, firstly, the surfaces and the interiors of the cabinet 1, the supporting legs 2, the cabinet door hinges 3, the door panels 11, the locking device 12 and the rain shelter 17 are all uniformly and repeatedly coated with insulating paint, and after drying, the rock wool board 18 is pasted around the inner wall of the cabinet 1, and then the three mounting frames 14 are connected to the fixing frame 4, and after the equipment table 15 and the electrical components 16 are installed on the fixing frame 4, the wiring harness connected to the equipment table 15 and the electrical components 16 is uniformly connected to the external wiring harness through the connection hole 5 and the external expansion tube 6, and the connection port is placed at the position of the connection hole 5. The powder bin 7, sensor 8, delivery pipe 9 and nozzle 10 are directly placed at the bottom of the cabinet 1 and connected to the power cord. They will be automatically triggered when a fire occurs. The awning 17 is placed on the top of the cabinet 1 and connected through the door buckle to a small password lock. It can be opened when needed and the password is managed uniformly. Then the door panel 11 is closed and the entire distribution cabinet is completely locked through the locking device 12. The equipment table 15 can be directly viewed through the inspection window 13 later. This can also reduce the number of door opening times. When maintenance is needed later, the door panel 11 and the awning 17 can be directly opened to carry out maintenance.
