Abstract

The invention belongs to the technical field of PLC control cabinets, and particularly relates to an energy-saving low-noise PLC control cabinet which comprises a cabinet body, a cabinet door is hinged to the front end of the cabinet body, a mounting groove is formed in the outer wall of the periphery of the cabinet door, an inflation hose adheres to the interior of the mounting groove, a first branch pipe is fixed to the front end of the cabinet door in a penetrating mode, and the top of the first branch pipe communicates with the inflation hose. The front end of the first branch pipe is sleeved with a balloon, the front end of the balloon is bonded with a second branch pipe, the front end of the second branch pipe is communicated with a connecting pipe, second sliding grooves are formed in the inner walls of the two sides of the second branch pipe, second sliding blocks are slidably connected into the second sliding grooves, and second springs are fixed between the second sliding blocks and the inner walls of the rear ends of the second sliding grooves. An exhaust block is fixed between the two second sliding blocks, and exhaust holes are formed in the front end and one side of the exhaust block. According to the invention, air in the cabinet body is pumped into the inflation hose, the door crack is closed, noise transmission is reduced, and meanwhile, the air content in the cabinet body is reduced, so that effective noise reduction is carried out.

Description

technical field [0001] The invention relates to the technical field of PLC control cabinets, in particular to an energy-saving and low-noise PLC control cabinet. Background technique [0002] The PLC integrated control cabinet has protection functions such as overload, short circuit, and phase loss protection. It has compact structure, stable operation and complete functions. It can be combined according to the size of the actual control scale, which can not only realize the automatic control of a single cabinet, but also realize the distribution (DCS) control system composed of multiple cabinets through industrial Ethernet or industrial field bus network. PLC control cabinets can adapt to industrial automation control occasions of various sizes. Widely used in electric power, metallurgy, chemical industry, papermaking, environmental protection sewage treatment and other industries. [0003] PLC control cabinets are generally equipped with cabinet doors, and the cabinet d...
