Technical Field

[0001] The utility model relates to the technical field of electric power engineering, in particular to a distribution box for electric power engineering. Background Art

[0002] A distribution box for power engineering is a device used to distribute and control electricity. It is usually installed in a building or at a key location in the power system. It contains multiple electrical components such as circuit breakers, fuses, contactors, relays, etc., which are used to control the direction and size of the current and protect the circuit safety.

[0003] The current distribution boxes used in power projects lack moisture-proof structures. When the distribution boxes are installed in relatively humid environments, such as humid basements or open air environments, the inside of the distribution boxes will be affected by the moisture in the air and become humid. The humid environment will increase the risk of short circuits in the distribution boxes, reducing the safety of the distribution boxes. In addition, the current distribution boxes lack emergency fire extinguishing devices. When a fire occurs in the distribution box, the flames cannot be suppressed in time, further reducing the safety of the distribution boxes. Utility Model Content

[0004] In order to overcome the above technical problems, the purpose of the utility model is to provide a distribution box for electric power engineering to solve the problem of lack of moisture-proof structure on the current distribution box of electric power equipment mentioned in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a distribution box for electric power engineering, comprising: a distribution box component group, the distribution box component group comprising a box body assembly and a cover body assembly, the box body assembly comprising a box body, a box frame member is arranged on one side of the box body, the cover body assembly comprises a cover body, a sealing ring is arranged on the outside of the cover body, a bolt member is arranged on the inside of the cover body, an attached box member is arranged on one side of the cover body, and a cover plate member is arranged on one side of the attached box member; a fire extinguishing component group is arranged at the bottom of the distribution box component group, and the fire extinguishing component group is used for emergency fire extinguishing inside the distribution box component group.

[0006] Preferably: the box body is connected to the box frame, the cover body is connected to the bolt member through threads, the box frame member and the bolt member are connected through threads, the cover body is provided with a groove at a position corresponding to the sealing ring, and the cover body contacts the sealing ring through the groove.

[0008] Preferably: the attached box part is connected to the cover body, a placement groove is provided in the attached box part, the placement groove on the attached box part is used to store the moisture-proof agent package, a plurality of ventilation holes are provided on the cover plate part, and the cover plate parts are connected to each other by screws.

[0009] Preferably, the fire extinguishing component group comprises an upper shell, a sealing cover is arranged on one side of the upper shell, a hanging rod is arranged inside the upper shell, and a hanging dry powder fire extinguisher is arranged on one side of the hanging rod.

[0010] Preferably, the upper shell is connected to the bottom of the box body, the box body is provided with a through groove at a position corresponding to the upper shell, and the upper shell and the sealing cover are connected by screws.

[0011] Preferably, one end of the hanging rod is connected to the upper shell, the hanging dry powder fire extinguisher is hung on the hanging rod by a hook, and the working end of the hanging dry powder fire extinguisher faces the box body.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. A distribution box for electric power engineering is provided with a distribution box component group. The current distribution box for electric power engineering lacks a moisture-proof structure. When the distribution box is installed in a relatively humid environment, such as a humid basement or an open-air environment, the distribution box will be affected by the moisture in the air and become humid. The humid environment will increase the risk of short circuit in the distribution box and reduce the safety of the distribution box. In the corresponding distribution box component group, the overall box assembly and the cover assembly are sealed by the components included. The external moisture will be blocked by the sealing structure composed of the box assembly and the cover assembly, and the moisture cannot enter the box body, and then cannot damage the electronic structure inside the box body. Water droplets condense on the structure to reduce the risk of short circuit, and the attached box member and the cover plate member connected to the cover body are connected by screws. The desiccant pack is stored in the attached box member through a placement groove, and the cover plate member is provided with air holes. The desiccant pack can absorb moisture in the box body, further ensuring the internal dryness of the sealed structure of the box body assembly and the cover body assembly, reducing the risk of short circuit of the internal electronic components. The sealing ring between the box frame member and the cover body ensures the sealing between the box frame member and the cover body. The overall design of this distribution box component group improves the sealing of the distribution box, which can effectively prevent external humid air from entering its interior, thereby reducing the risk of short circuit of the internal electronic components of the distribution box;

[0014] 2. The distribution box for power engineering is provided with a fire extinguishing component group. The current distribution box lacks an emergency fire extinguishing device. When a fire occurs in the distribution box, the flame cannot be suppressed in time, further reducing the safety of the distribution box. In the corresponding designed fire extinguishing component group, when the electronic components in the box body below the fire extinguishing component group catch fire, the surrounding temperature will rise. When it reaches sixty degrees Celsius, the hanging dry powder fire extinguisher will be triggered to open. After opening, the dry powder fire extinguishing agent will be sprayed toward the inside of the box body through the working end, and then the flame of the burning electronic components will be suppressed, which increases the reaction time of subsequent manual fire extinguishing, thereby improving the safety of the overall distribution box. When the hanging dry powder fire extinguisher expires, the hanging dry powder fire extinguisher mounted on the hanging rod can be replaced by removing the sealing cover, which is convenient for safety inspectors to inspect and replace.
