Technical Field

[0001] The utility model relates to the field of electrical equipment, in particular to an environmental protection cabinet which is convenient for internal inspection. Background Art

[0002] The power distribution cabinet is a commonly used power distribution equipment. The power distribution cabinet generally includes a cabinet body and a power distribution module installed in the cabinet body. The power distribution module will generate a lot of heat during operation. A large number of power distribution modules are arranged in a large space of the cabinet body. The heat between the power distribution modules will be transferred to each other, resulting in concentrated heat and difficulty in heat dissipation. It is difficult for the external airflow to take away the internal heat. At the same time, since it is arranged in a sealed space and lacks a fire extinguishing structure, once the power distribution module therein spontaneously ignites, it will cause the fire to spread rapidly.

[0003] Therefore, it is necessary to provide a new environmental protection cabinet that is convenient for internal inspection to solve the above technical problems. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides an environmental protection cabinet which is convenient for internal inspection, and solves the problems of heat dissipation difficulty and lack of fire extinguishing structure in the existing power distribution cabinet.

[0019] Beneficial effects of the utility model:

[0020] 1. When the environmental protection cabinet is in use, the motor starts (forward rotation) to drive the transmission shaft to rotate. Under the transmission action of the first bevel gear and the third bevel gear, the installation shaft will rotate and drive the blades to rotate, and finally the outside air will be sucked into the cabinet to speed up the heat dissipation of electrical components and avoid overheating and spontaneous combustion of electrical components;

[0021] 2. When the electrical components spontaneously combust, the smoke sensor module installed inside the cabinet will transmit a signal to the central controller. At this time, the lifting seat will move down under the action of gravity until it contacts the surface of the fixed seat. During the downward movement of the lifting seat, the closing plate will block the first waterproof ventilation slot to prevent outside air from entering. At the same time, the central controller controls the motor to reverse, so that the blades will reverse and extract the air inside the cabinet.

[0022] When the lifting seat moves downward, it will drive the top rod to move downward. When the pressure strain gauge is separated from the top of the cabinet, the pressure strain gauge can transmit the signal to the central controller, and then the central controller controls the solenoid valve to open. At this time, a large amount of inert gas enters the cabinet, further accelerating the fire extinguishing speed. In summary, this environmental protection cabinet can extinguish the fire source in time, greatly reduce the amount of burning wires and the toxic gases generated by the combustion, reduce air pollution, and is highly environmentally friendly.

[0023] 3. By setting up a fill light, the brightness inside the cabinet can be increased, which is convenient for the staff to inspect the circuit. By setting up a placement table with a placement slot, it is convenient for the staff to place maintenance tools, and the placement table can be moved to the side close to the lifting seat when not in use.

[0034] A rain shield 14 is fixed on the ventilation pipe 3, and a plurality of second waterproof ventilation grooves 15 are opened on the rain shield 14 to prevent rainwater from entering the cabinet 1 when it rains. A mounting ring 16 is detachably mounted on the ventilation pipe 3 by bolts, and a dustproof net 17 is installed on the mounting ring 16. The air entering the cabinet 1 can be filtered through the dustproof net 17.

[0035] Two fixed seats 20 are fixed at intervals inside the cabinet 1, a guide rail 21 is fixed between the fixed seat 20 and the top of the cabinet 1, a lifting seat 22 is slidably arranged on the guide rail 21, a closing plate 23 is fixed between the two lifting seats 22, one side of the closing plate 23 is in contact with the inner wall of the cabinet 1, two electric telescopic rods 24 are symmetrically installed on one side of the cabinet 1, a support rod 25 is penetrated through the inner wall of the cabinet 1, the support rod 25 is slidably connected to the cabinet 1, and the upper surface of the support rod 25 is in contact with the bottom of the lifting seat 22. When the electrical component 9 spontaneously ignites, The smoke sensing module arranged inside the cabinet 1 will transmit the signal to the central controller, and then the central controller will control the output end of the electric telescopic rod 24 to drive the support rod 25 to move and separate from the lifting seat 22. At this time, the lifting seat 22 will move down under the action of gravity until it contacts the surface of the fixed seat 20. During the downward movement of the lifting seat 22, the closing plate 23 will block the first waterproof ventilation slot 7 to prevent outside air from entering.
