Automatic waterproof high and low voltage power distribution cabinet with high safety performance

Abstract

The invention discloses an automatic waterproof high and low voltage power distribution cabinet with high safety performance, which belongs to the technical field of high and low voltage power distribution cabinets, and comprises a main body of the high and low voltage power distribution cabinet, and a floating plate is arranged under the main body of the high and low voltage power distribution cabinet , the top of the floating plate is fixedly connected with a connecting shaft, the surface of the connecting shaft is sleeved with a sliding sleeve, and the sliding sleeve is clamped in the telescopic groove opened at the bottom of the main body of the high and low voltage power distribution cabinet. In the present invention, through the designed connecting shaft, floating plate, torsion spring, torsion shaft, gear shaft, tooth plate, telescopic groove, sealing ring, sliding sleeve, ball valve, first ventilation hole, second ventilation hole and perforation, etc. With the mutual cooperation of the structure, the loss caused by the natural environment such as rainy seasons to the main body of the high and low voltage power distribution cabinet is reduced, and the ventilation function of the perforation can be automatically restarted. The automatic adjustment mechanism is simple, and no external power or hydraulic pressure is required. Automated drive equipment is low in cost and easy to implement.

Description

technical field [0001] The invention belongs to the technical field of high and low voltage power distribution cabinets, in particular to an automatic waterproof high and low voltage power distribution cabinet with high safety performance. Background technique [0002] As the name implies, the high and low voltage power distribution cabinet is the power distribution equipment used for power distribution, control, metering and cable connection in the power supply system. Generally, power supply bureaus and substations use high-voltage switchgear, and then step down the low-voltage side through transformers. It leads to the low-voltage power distribution cabinet, the low-voltage power distribution cabinet and then to the power distribution boards, control boxes, and switch boxes. Inside are protective devices such as switches, circuit breakers, fuses, buttons, indicators, meters, and wires. A device that is assembled into a power distribution device that meets the design funct...

AI Technical Summary

Problems solved by technology

[0003] High and low voltage power distribution cabinets are divided into indoor and outdoor. Outdoor power distribution cabinets are not easy to fix, and are usually placed directly on the ground. At present, in order to improve the waterproof performance of high and low voltage power distribution cabinets, it is usually installed on the door of the cabinet. Waterproof sealing ring, although the waterproofness has been gradually improved, in order to ensure the heat dissipation effect inside the high and low voltage power distribution cabinet, a ventilation port is usually set on the surface of the cabinet body, and the setting of the ventilation port is easy to appear on the road. When there is a large amount of water, there will be water ingress, and the phenomenon of water ingress will easily cause the electronic components inside the main body of the high and low voltage power distribution cabinet to be eroded by rainwater, and it will also bring a lot of sludge cleaning work. Therefore, an automatic waterproof high and low voltage power distribution cabinet with high safety performance is urgently needed in the market at this stage to solve the above problems
