Liftable weak current box and weak current well

Abstract

The invention discloses a liftable weak current box and a weak current well. The weak current well and the weak current box body located in the weak current well are included. Slide blocks protrudingout of a surface of the weak current box body are arranged on side surfaces, which are in contact with an inner wall of the weak current well, of the weak current box body. Slideways corresponding topositions of the slide blocks are arranged on the inner wall of the weak current well. A rotating shaft is arranged above a top wall of the weak current well. A pressure-bearing cable is arranged on the rotating shaft, one end of the pressure-bearing cable is fixedly connected with the slide blocks, and the other end is fixedly connected with the rotating shaft and wound on the rotating shaft. Therotating shaft is driven by a motor, a fire extinguishing device capable of being opened through descending of the weak current box body is further arranged at a bottom of the weak current well. A top of the fire extinguishing device is in contact with bottom end surfaces of the slideways. The weak current box body is controlled to ascend and descend through rolling and releasing of the pressure-bearing cable, an outlet of the fire extinguishing device is opened through the weak current box body to achieve a purpose of fire extinguishing, the weak current box is effectively placed in different spaces, and on the basis that a fire behavior of the weak current box is rapidly and timely handled, an influence outside the weak current well is minimized.

Description

technical field [0001] The invention relates to the field of centralized control equipment for weak current pipelines, in particular to a liftable weak current box and a weak current well. Background technique [0002] The weak current shaft is a vertical shaft built for the convenience of laying cables for the weak current system of the building, referred to as the weak current shaft. The rapid development of building intelligence for many years has made weak current wells widely used in various buildings, and the use of weak current wells has also made the planning and design of building intelligence more standardized. The weak current lines in the weak current well include the lines of computer network, cable TV, mobile phone signal, monitoring system, etc., and these lines are concentrated in the weak current box for control. [0003] In the public area of ​​the building, when an accident occurs, the existence of monitoring and sensors can detect the accident in time, b...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art that when a fire is found at the place where the weak current box is placed in the weak current well, it cannot quickly and timely deal with the fire on the basis of less impact on the outside of the weak current well, and provides a liftable weak current box and Weak electric well, by lifting and lowering the weak electric box in the weak electric well, the weak electric box can be effectively placed in different spaces, and the impact on the outside of the weak electric well can be minimized on the basis of quick and timely handling of the fire of the weak electric box
