Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing technology, specifically to an auxiliary fire extinguishing system for industrial plants. Background Technology

[0002] In recent years, industrial plant fires have occurred frequently. With economic and technological development, industrial scale is expanding rapidly, and the individual building areas of factories in various industries are becoming increasingly larger. Faced with the frequent fires causing personal injury and economic losses, fire control and buying precious rescue time have become increasingly important.

[0003] Currently, the design of fire protection systems for factory interiors is quite mature; however, fire protection systems for factory roofs are relatively scarce. Existing industrial factory roofs generally use a two-layer structure of profiled steel sheets with fiberglass insulation in between. When a fire is large and the roof insulation layer is affected, fire-fighting water may have difficulty reaching the inner layer to extinguish the fire, making the fire difficult to control and allowing it to spread. Utility Model Content

[0004] The purpose of this invention is to develop an auxiliary fire extinguishing system for industrial buildings that can extinguish fires on the roof of the factory building and prevent the fire in the internal interlayer from spreading to the roof and other areas.

[0005] This utility model is achieved through the following technical solution:

[0026] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of the invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0027] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] like Figures 1-3 As shown, this utility model discloses an auxiliary fire extinguishing system for industrial buildings, including a factory roof 100, with a main pipe 200 provided on the ridge line of the factory roof 100, and the main pipe 200 arranged along the ridge line of the factory roof 100.

[0030] Two main pipes 200 are installed at the ridge line of the factory roof 100. The two main pipes 200 enter the factory roof 100 from both ends of the ridge line. A main valve 201 is installed at the end of each main pipe 200 outside the ridge line. Multiple branch pipes 300 are connected to both sides of the main pipes 200. A branch valve 301 is installed on the branch pipes 300 where they connect to the main pipes 200. Both the main valve 201 and the branch valve 301 are solenoid valves and can be remotely controlled.

[0031] In addition, the branch valve 301 may not be installed at the connection between the branch pipe 300 and the main pipe 200, and the main valve 201 may be a manual valve and installed on the ground or in other places that are easy for personnel to operate. In the event of a fire, personnel can open the main valve 201 to extinguish the fire.

[0032] The branch pipe 300 is perpendicular to the main pipe 200, and is inclined and parallel to the roof 100 of the factory building on which it is located. The end of the branch pipe 300 away from the main pipe 200 is a closed end. At least one set of spraying components is provided at the bottom of the branch pipe 300. The spraying components include multiple spray holes 302 arranged at equal intervals along the axial direction of the branch pipe 300. When there is one set of spraying components, the spraying components are located at the bottom end of the branch pipe 300. When there are multiple sets of spraying components, the multiple sets of spraying components are arranged at equal intervals in the circumferential direction of the branch pipe 300.

[0033] The multiple branch pipes 300 on both sides of the main pipe 200 are arranged at equal intervals on the main pipe 200. The multiple branch pipes 300 on both sides of the main pipe 200 are staggered by half a distance, that is, one of the branch pipes 300 on the left or right side of the main pipe 200 is located between the two branch pipes 300 on the right or left side.

[0034] The factory roof 100 includes fiberglass insulation cotton 103. A layer of profiled steel sheet 102 is provided on the top and bottom of the fiberglass insulation cotton 103. Multiple purlins 101 are provided at the bottom of the profiled steel sheet 102 at the bottom of the fiberglass insulation cotton 103. The purlins 101 are connected to the factory building support structure. The main pipe 200 and branch pipe 300 are arranged in the fiberglass insulation cotton 103.

[0035] Given that the water absorption rate of fiberglass insulation cotton 103 is very low, usually <1%, it will not increase the roof load due to water absorption. Therefore, the main pipe 200 is connected to the fire water source, using water as the fire extinguishing medium.

[0036] In addition to this embodiment, the spacing of the branch pipes 300, as well as the density and position of the branch pipes 300 on both sides, can be set according to the fire hazards in the factory. For example, the density of the branch pipes 300 can be increased in areas with high fire hazards, while the density of the branch pipes 300 can be reduced in areas with low or almost no fire hazards.

[0037] Under normal conditions (when no fire occurs), only the main pipe 200 is filled with water. When a fire spreads to the roof of a certain area in the factory, and the fiberglass insulation cotton 103 of the factory roof 100 is affected by the fire, the main valve 201 opens, and the main pipe 200 is filled with water. At the same time, the branch valve 301 of the branch pipe 300 covering the corresponding fire area opens, and the branch pipe 300 is filled with water. The water is sprayed out from the sprinkler hole 302, and the factory roof 100 in the fire area is sprayed to prevent it from being affected by the fire. In addition, since the pipe is located at the highest point of the factory roof 100, the water will flow to the lower part of the roof under gravity. The area through which the water flows will also achieve the fire extinguishing effect, reduce the impact of the fire, and prevent or suppress the spread of the fire.

[0038] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the technical solutions of this utility model. Any technical solution that can be implemented based on the above embodiments without creative effort should be considered to fall within the scope of protection of this utility model patent.
