Fire-fighting wall-passing platform for ultra-high and ultra-wide shielding darkroom

Abstract

The invention relates to a fire-fighting wall-passing platform for the ultra-high and ultra-wide shielding darkroom, including a shielding passage arranged on the shielding wall, a fire shielding dooron the outside of the shielding tunnel, and a fire-fighting platform which is arranged on the inside of the shielding channel through hinges and is flush with the shielding wall after being fastened,wherein a protective ring chain is arranged between the upper end of the shielding channel and the free end of the fire-fighting platform, and a fire hydrant is installed on the fire-fighting ring corridor outside the shielding channel; the fire-fighting wall-passing platform can be installed at the middle height of the shielding wall, the fire extinguishing requirements for the ultra-high and ultra-wide shielding darkroom can be met by using the shielding passage, the unfolding of the fire-fighting platform and the fire hydrant on the fire-fighting ring corridor, fire-fighting passages of different heights are provided for the fire hydrant extinguishing system of the ultra-high and ultra-wide darkroom under the premise of ensuring the shielding performance and the microwave absorbing performance of the darkroom, and the problem that the range of the ground fire hydrant is insufficient can be solved.

Description

technical field [0001] The invention relates to a fire-fighting over-the-wall platform facing an ultra-high shielded darkroom. Background technique [0002] For ordinary shielded darkrooms, ground fire hydrants are generally used to extinguish fires. When extinguishing fires, spraying water to the fire point outdoors can meet the requirements of fire protection design specifications. However, for large darkrooms with ultra-high and ultra-wide widths, the fire hydrant protection range is limited by the full water column distance during fire extinguishing, and the ground is covered with absorbing materials and it is difficult to enter the room. Therefore, the ground fire hydrant cannot meet the protection range requirements in the fire protection design code. It is a fire-fighting device for super-high and super-large shielded darkrooms. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a fire-fighting over-the-wall...
