Description

Technical Field

[0001] The utility model belongs to the technical field of fire protection engineering, is used when fixing gas cylinders in a cylinder storage room of a gas fire extinguishing system and when double-row cylinders are fixed off the ground, and specifically relates to an adjustable gas fire extinguishing cylinder adjustable support frame. Background Art

[0002] As the functions of buildings become increasingly complex, the number of gas fire extinguishing system cylinders required in the transformer substation is gradually increasing. In the case of limited building space, double-row arrangement of cylinders has gradually become a solution to save construction project costs. The conventional arrangement is to fix the cylinders in double rows, that is, the cylinders are placed back to back, with a horizontal beam in the middle. Double-row fixation means that the system header is installed on a single column, and the column landing position is supported by a triangle. When the double-row cylinders are fixed, the cylinders are placed directly on the ground. When multiple cylinders are placed back to back in a row, the cylinder support frame has insufficient seismic resistance. Once an earthquake occurs, the gas cylinders will tilt due to the lack of sufficient limiting measures, dragging the hose connected to the gas collector, and then causing damage to the gas fire extinguishing system. There is a possibility that the fire extinguishing device will fail prematurely, causing hidden dangers in the subsequent use of the transformer substation fire extinguishing system.
