Problems solved by technology
[0003] Traditional power distribution cabinets are generally provided with vents to dissipate heat inside the cabinet. The power distribution cabinets installed in the water power station are located close to the river. During the rainy season, as the water level rises, it is easy to cause the cabinet If the body is flooded, water will enter the cabinet, which will easily cause a short circuit in the circuit inside the cabinet, cause the electrical components inside the cabinet to not work normally, and easily cause electric leakage, causing the staff to have the risk of electric shock when passing by. Therefore, It is necessary to design an automatic flood control distribution cabinet for electric power to solve the above problems

The invention discloses anautomatic flood prevention power distribution cabinet for electric power, whichcomprises a cabinet body, wherein four supporting columns are fixedly connected to the lower wall of the cabinet body, a ventilation opening is formed in the side wall of the cabinet body in a penetrating mode, a groove is formed in the inner wall of the ventilation opening, a baffle capable of moving up and down is arranged on the inner wall of the groove, and a sliding groove is formed in the inner wall of the cabinet body and communicates with the groove; the side wall of the baffle is fixedly connected with a connecting rod, and the end, away from the baffle, of the connecting rod is fixedly connected with a rack. When the water surface rises, the baffle blocks the ventilation opening, water can be prevented from entering the cabinet body, normal work of electrical components in the cabinet body is further ensured, the airtightness of the baffle and the groove can be improved through expansion of the air bag, and the waterproof effect of the cabinet body is further improved. Besides, a problem that electrical apparatus elements in the cabinet body are damaged due to the fact that the internal temperature of the cabinet body is too high during sealing can be prevented, repeated use can be achieved, and the economic applicability of the device is improved.
Description
technical field [0001] The invention relates to the technical field of power distribution cabinets, in particular to an automatic flood control power distribution cabinet for electric power. Background technique [0002] The power distribution cabinet is the final equipment of the power distribution system, and it is also the general name of the motor control center. The electric energy of a certain circuit of the upper-level power distribution equipment is distributed to the nearest load. [0003] Traditional power distribution cabinets are generally provided with vents to dissipate heat inside the cabinet. The power distribution cabinets installed in the water power station are located close to the river. During the rainy season, as the water level rises, it is easy to cause the cabinet If the body is flooded, water will enter the cabinet, which will easily cause a short circuit in the circuit inside the cabinet, cause the electrical components inside the cabinet to not w...
