Ventilation grid for comprehensive pipe rack war

Abstract

The invention relates to a ventilation grid for comprehensive pipe rack war. The ventilation grid comprises a ventilation port; a grid stretches over in the ventilation port in a sealing mode; the grid comprises a frame body connected to the inner wall of the ventilation port; multiple first grid bars are arranged in the frame body in parallel at intervals; second grid bars for closing the whole grid are arranged between the adjacent first grid bars; one ends of the multiple second grid bars penetrate through, and are fixedly connected with rotating shafts; the rotating shafts penetrate through, and are rotationally connected to the first grid bars and the frame body; driving pieces for driving the rotating shafts to rotate and driving the multiple second grid bars to move between the adjacent first grid bars are arranged on the outer wall of the ventilation port; the ventilation port is closed by the first grid bars and the second grid bars for preventing part of rainwater from entering a comprehensive rack; and when the air attack occurs, the first grid bars and the second grid bars can achieve a stop effect on impact force of guided missiles or other explosives to prevent damageof pipes in the comprehensive rack so as to prevent paralysis of the whole city.

Description

technical field [0001] The invention relates to the technical field of civil air defense facilities, in particular to a ventilation grille for both peacetime and wartime use in a comprehensive utility gallery. Background technique [0002] The combination of peacetime and wartime refers to the soft and hardware facilities in all aspects of civil air defense construction, which are used in society in peacetime without affecting the air defense capability in wartime. The comprehensive pipeline corridor is the comprehensive corridor of underground urban pipelines. That is to build a tunnel space underground in the city, integrating various engineering pipelines such as power, communication, gas, heating, water supply and drainage, etc., with special inspection ports, hoisting ports and monitoring systems, implementing unified planning, unified design, Unified construction and management is an important infrastructure and "lifeline" to ensure the operation of the city.

AI Technical Summary

Problems solved by technology

[0005] But its disadvantage is that the existing grids usually include a plurality of grid bars arranged horizontally and vertically. When it rains heavily, the rainwater will enter the integrated pipe gallery through the gaps between the bars, and the cables in the integrated pipe gallery will be affected. Or pipelines cause damage. For example, in wartime, if an air strike occurs, the impact force of the missile will impact the position of each pipeline in the comprehensive pipeline gallery through the gaps between the grids, causing a large area of ​​pipelines to be paralyzed, causing the entire city to fall into a trap. paralyzed situation
