Description

TECHNICAL FIELD

[0001] The utility model relates to safe fire control equipment installation technical field, concretely for a kind of linear light beam smoke detector's fixing device in joint workshop. BACKGROUND

[0002] The joint workshop of cigarette factory is a large building integrating multiple production functions, usually including raw material processing, silk making, rolling and connecting, packaging and other processes. This design can improve production efficiency, reduce material handling and optimize production process. This joint workshop includes more columns, beams, inclined beams, ceilings and other structures, with the characteristics of efficient and convenient construction. Tobacco is a flammable material, and high-temperature equipment is involved in the production process, so there is a high risk of fire. Smoke detectors can detect smoke in the early stages of a fire and send out an alarm in time to give valuable time for personnel evacuation and fire extinguishing. Many countries and regions have strict fire safety regulations, requiring the installation of fire detection systems in industrial sites. Therefore, it is necessary to install a smoke detector in the joint workshop of a cigarette factory. Linear light beam smoke detectors are installed on the upper space, and the installation position is high, usually installed on the wall. In order to meet the distance requirements of the detector and reflector of the linear light beam smoke detector in the joint workshop, the linear light beam smoke detector needs to be installed on the triangular net rack steel pipe 0.3-1 meters away from the roof.

[0003] During actual installation, maintaining the reflector and detector at the same horizontal height may cause installation difficulties due to the complex internal structure of the joint workshop, as the height of the beams in different areas may differ. In actual operation, when installing the smoke detector, it is inconvenient to adjust the height position, and two people are needed to install simultaneously in the air, two vertical rod supports need to be installed on both sides of the beam pipe, and the two supports need to be connected by four screw rods, which makes the installation process inefficient. In addition, two sets of supports and detectors need to be installed on one beam, which will cause waste of structural materials, increase of fixed points, and need for mutual tensioning and fixing of the upper end in addition to the bottom. Moreover, point contact is formed between the two supports relative to the surface of the beam, and the equipment consumes more heavy materials, which is prone to tilting in the later stage. Once tilted, the detector may fail, resulting in the need for frequent maintenance and calibration of the bolt. SUMMARY
