Dustproof communication cabinet

Abstract

The invention provides a dustproof communication cabinet, belongs to the technical field of electric power, and solves the problem that an existing communication cabinet cannot guarantee the dustproof effect while dissipating heat. According to the dustproof communication cabinet, an air supply pipe communicated with an equipment installation cavity is fixed to the upper portion of an air inlet cavity, an air spraying pipe is arranged in the equipment installation cavity and communicated with the air supply pipe, the lower portion of the air spraying pipe is located at the bottom of the equipment installation cavity, a plurality of air spraying heads are fixed to the lower portion of the air spraying pipe, and an air draft assembly is arranged on the upper portion of the air inlet cavity; a filter assembly located between the air inlet hole and the air supply pipe is arranged on the inner wall of the air inlet cavity and comprises a mounting frame fixed to the inner wall of the air inlet cavity in a sliding mode, a dust filter screen is arranged on the inner circumference of the mounting frame, a plurality of springs are arranged on the upper side of the mounting frame, the upper ends of the springs are connected with a supporting frame, and the supporting frame is fixedly connected with the inner wall of the air inlet cavity. According to the invention, the dustproof effect is improved while the heat dissipation effect is ensured, and the dust filter screen is convenient to clean.

Description

technical field [0001] The invention belongs to the technical field of electric power, and relates to a communication cabinet, in particular to a dustproof communication cabinet. Background technique [0002] The power communication network came into being in order to ensure the safe and stable operation of the power system. Together with the relay protection, safety and stability control system and dispatching automation system of the power system, it is collectively called the three pillars of the safe and stable operation of the power system. At present, it is the foundation of power grid dispatching automation, network operation marketization and management modernization; it is an important means to ensure the safety, stability and economic operation of power grid; it is an important infrastructure of power system. Because the power communication network has strict requirements on the reliability of communication, the speed and accuracy of protection and control informa...

Problems solved by technology

[0004] Although the exhaust fan, dust-proof net, dust-cleaning brush and dust collection box disclosed in this patent can play the role of heat dissipation and dust-proof and clean the dust-proof net, the device is to dissipate heat by means of draft. When ventilating, the wind generated by it enters the cabinet through the cabinet door to dissipate heat from the working parts. The dust generated in the air is easily adsorbed to the working parts and pollutes the working parts. Only part of the dust can be adsorbed to the dust-proof net. The dust-proof effect is limited, and because the dust is on the side of the dust-proof net close to the working parts, when the dust-proof net is cleaned with a dust-cleaning brush, it is easy to generate dust, which will pollute the working parts again
