[0002] The distribution box is a low-voltage electrical wiring system that requires the assembly of switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-enclosed metal cabinet or on a screen. It is also the control center that directs the reasonable distribution of electric energy among various components in the power supply line, the control link that correctly feeds out load electric energy, and the key to whether users are satisfied with the power supply quality. The explosion-proof distribution box is a type of distribution box with explosion-proof performance. It is suitable for power distribution in flammable and explosive places such as chemical industry, pharmaceutical industry, coal, smelting, shipbuilding, textile, etc.

[0003] When the internal temperature of the distribution box on the market is too high for a long time during use, it is easy to cause the internal electrical equipment to overheat and explode, and its safety is low. For this reason, we propose an explosion-proof distribution box with gas detection function. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an explosion-proof distribution box with a gas detection function, comprising a body, a support, a ventilation member and a fire extinguishing member, wherein a support is arranged inside the body, and a ventilation member is arranged below the support, and a fire extinguishing member is arranged on the top of the support, the ventilation member comprises a ventilation chamber, a vent, a fan assembly, a desiccant chamber and a filter plate, and vents are arranged on the left and right sides of the ventilation chamber, a fan assembly is arranged at one end of the vent, and a desiccant chamber is arranged on the side of the fan assembly, and a filter plate is arranged above the ventilation chamber.

[0006] Furthermore, the vent is connected to the fan assembly, and the fan assembly is fitted to the desiccant chamber.

[0007] Furthermore, the fire extinguishing component includes a nozzle, a dry powder connecting pipe and an air pump, and the end of the nozzle is provided with a dry powder connecting pipe, and the end of the dry powder connecting pipe is provided with an air pump.

[0008] Furthermore, the nozzle is connected to the air pump.

[0009] Furthermore, the support member includes a support rod, a wiring board and a fastener, and the wiring board is arranged at one end of the support rod, and the fasteners are arranged around the wiring board.

[0010] Furthermore, the wiring board forms a threaded structure with the support rods through fasteners.

[0011] Furthermore, the machine body includes a cabinet, a temperature sensor, a detection probe and a buzzer alarm component, and the temperature sensor is arranged on the left side of the interior of the cabinet, the detection probe is arranged on the right side of the interior of the cabinet, and the buzzer alarm component is arranged on the upper middle part of the outer side of the cabinet.

[0012] Compared with the prior art, the beneficial effects of the utility model are: the explosion-proof distribution box with gas detection function allows air to circulate in the cabinet through the bottom vents when the heat is too high. When the electrical components catch fire due to excessive heat, the temperature sensor detects the temperature change and transmits the data to the buzzer alarm component to sound an alarm. Then the air pump on the top will spray the dry powder inside the dry powder box through the nozzle to extinguish the flames.

[0013] A ventilation chamber and vents are provided at the bottom of the distribution box to allow outside air to enter the interior, and the desiccant chamber provided at the vents can dry the moisture in the humid air to reduce the damage caused by the humid air to the internal components. At the same time, a fan assembly is provided at one end of the vent. When the internal temperature is too high, the fan assembly is used to exhaust air so that the internal heat can be dissipated, so that the internal components will not be damaged by high temperature and will not explode due to overheating. The setting of the filter plate can prevent flying insects from entering the cabinet to damage the components and avoid safety hazards.

[0014] The nozzle is connected to the air pump. When the gas concentration inside the distribution box is too high and causes a fire, the detection probe on the right will conduct detection, and the buzzer alarm component above will sound an alarm. At the same time, the air pump on the top will spray the dry powder inside the dry powder box through the nozzle to extinguish the flames, ensuring that the fire will not expand before the arrival of staff, and that the components inside the distribution box body will not be further damaged. The overall explosion-proof performance is better, which improves a certain degree of safety. BRIEF DESCRIPTION OF THE DRAWINGS
