[0004] Therefore, it is necessary to propose a power box for power engineering to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a power box for power engineering, in order to solve the problem that during peak electricity consumption periods, the internal electrical components and wires of the power box are prone to short circuits, which can easily lead to fires. If personnel cannot detect the fire in time, it can easily cause the fire to spread too much and result in significant economic losses.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a power box for power engineering, comprising a power box body, a dry powder gas bag fixed to the top of the inside of the power box body, the dry powder gas bag being filled with fire extinguishing dry powder, an L-shaped bracket provided on one side of the dry powder gas bag, the top of the L-shaped bracket being fixed to the top of the inside of the power box body, and a flame sensor being fixed to the bottom of the L-shaped bracket.

[0007] An electric push rod is fixed on the L-shaped bracket, and a needle is fixed at the top of the electric push rod. The needle is located below the dry powder gas bag. A protruding box is fixed at the bottom of the outer side of the power box. Multiple exhaust holes are opened on the protruding box and are connected to the outside.

[0008] Preferably, the bottom of the power box has multiple through holes, the top of which are connected to the inside of the power box, and the bottom of which are connected to corresponding exhaust holes.

[0009] Preferably, the power box has fixing blocks on both sides inside, the two fixing blocks are positioned correspondingly, and the bottom of the two fixing blocks is provided with a sliding groove. The two sliding grooves are fitted with protruding blocks, the bottom of the two protruding blocks are fixed with a base plate, and the two base plates are fixed with a mounting bracket.

[0010] Preferably, each of the two protruding blocks has a fixing hole on one side of its opposite side, and the fixing block has an insertion hole corresponding to the fixing hole. A fixing screw is provided between the fixing hole and the insertion hole.

[0011] Preferably, the power box is hinged with a door.

[0012] Preferably, the mounting bracket has a connection slot for mounting electrical components along its length.

[0013] Preferably, the inner wall of the power box is coated with fire-retardant paint.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. In the actual operation of this utility model, when the flame sensor detects a short circuit in the electrical components inside the electrical box causing a fire, the flame sensor detects the generation of flames and transmits the information to the controller, which will cause the electric push rod to extend upward, thereby causing the needle to puncture the dry powder gas bag, so that the dry powder can extinguish the fire inside the electrical box from top to bottom, reducing the time for manual firefighting, reducing economic losses, and improving fire extinguishing efficiency.

[0016] 2. Furthermore, after the dry powder is sprayed out, some of the dry powder enters the multiple through holes due to its own gravity, and as it continues to descend, it is finally discharged to the outside through the vent. Before the door is opened, it alerts personnel to the fire inside and uses the dry powder to extinguish the fire, preventing personnel from opening it unintentionally and causing injury. At the same time, the vent can serve as a heat dissipation channel under normal conditions. Attached Figure Description
