Multifunctional power distribution cabinet for communication base station

Abstract

The invention discloses a multifunctional power distribution cabinet for a communication base station. The cabinet comprises a cabinet body, and a partition plate is arranged in the cabinet body. Thespace between the upper end face of the partition plate and the cabinet body is filled with a fire extinguishing agent. An installation cylinder is inserted into the partition plate, a sliding block is connected into the installation cylinder in a sealing and sliding mode, and a linkage mechanism is arranged on the sliding block. A plurality of ventilation openings are symmetrically formed in thecabinet body, and a plurality of closing mechanisms corresponding to the ventilation openings are arranged on the cabinet body. A rotating shaft is installed in each ventilation opening through a torsional spring, and a fan is arranged on each rotating shaft. According to the invention, external energy input is not needed, the fans are driven to rotate periodically by gasification and liquefactionof evaporated liquid, so that hot air in the cabinet body is exhausted intermittently, external cold air is sucked in intermittently, the flowing speed of the air in the cabinet body is increased, the cooling and heat dissipation effects are obvious, and energy conservation and environmental protection are achieved. Meanwhile, when a fire occurs in the cabinet body, the fire can be extinguished in time, and spreading of the fire is avoided.

Description

technical field [0001] The invention relates to the technical field of power equipment, in particular to a multifunctional power distribution cabinet for a communication base station. Background technique [0002] The communication base station is the most critical infrastructure in the mobile communication network. The communication base station generally has structural components such as machine rooms, wires, iron towers and masts. With the rapid development of mobile communication network services, the construction coverage of mobile communication base stations is becoming wider and wider. It has Become an important part of the investment of communication operators. [0003] Power distribution cabinets are generally used in the construction of communication base stations to install various electrical equipment. When the electrical equipment is running, a large amount of heat will be emitted. When the heat in the cabinet cannot be discharged in time, the internal temperatu...
