Technical Field

[0001] The utility model relates to the field of high-rise building fire fighting, in particular to an automatic fire extinguishing device for the exterior wall of a high-rise building. Background Art

[0002] For a long time, building fires have occurred from time to time. The fierce fire on the building's exterior wall often quickly engulfs the entire building, causing huge property losses and casualties. If low-rise single-story and multi-story buildings are easy for firefighters to put out, then high-rise buildings and even super high-rise buildings face huge difficulties in putting out fires, leaving firefighters helpless. This is also a very difficult problem for high-rise buildings that cannot be rescued. Utility Model Content

[0005] Preferably, the solenoid valve switch 9 is arranged at an inner position close to the outer wall 1 of the building.

[0006] Preferably, the casing 7 is provided with a water-retaining steel plate.

[0007] Preferably, the dry fire-fighting pipe 10 is fixed on the structural floor beam 4 by means of a U-shaped clip 11 and a steel nail 12 .

[0008] Preferably, the gap between the sleeve 7 and the water supply pipe 8 is sealed with sealant.

[0009] The utility model has the beneficial effects of simple structure, strong concealment, simple and convenient construction, effectively preventing fire from occurring, reducing the spread of fire, and winning precious rescue time for firefighters to carry out targeted firefighting.

Water supply pipe; 9. Solenoid valve switch; 10. Dry fire fighting pipe; 11. U-shaped clip; 12. Steel nails; 13. Water spray holes; 14. Water spray trajectory; 15. Wires. DETAILED DESCRIPTION

[0013] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0014] like Figure 1 and Figure 2 As shown, an insulation layer is arranged on the outside of the building's exterior wall, a decorative layer is arranged on the outside of the insulation layer, a casing is pre-buried in the structural floor beam at the building's exterior wall floor position, a water supply pipe with a solenoid valve switch is inserted into the casing, and the water supply pipe is connected indoors to the water supply pipe of the original fire hydrant fire extinguishing system or automatic sprinkler fire extinguishing system in the building. The solenoid valve switch can be arranged at an appropriate position on the inside near the building's exterior wall.

[0015] In order to prevent water seepage problems between the casing and the structural floor beams, casing with water-retaining steel plates can be used.

[0016] A dry fire-fighting pipe with a plurality of water spray holes is arranged in the horizontal direction of the outer side of the structural floor beam. The dry fire-fighting pipe is connected with the water supply pipe and is fixed on the structural floor beam.

[0017] The dry fire-fighting pipe can be fixed on the structural floor beam by fixing the dry fire-fighting pipe on the structural floor beam by a plurality of U-shaped clips through steel nails.

[0018] A heat-sensitive soluble element is embedded in the lower layer of the structural floor beam, and the heat-sensitive soluble element is connected to the electromagnetic valve switch through a wire. The purpose of installing the heat-sensitive soluble element in the lower layer of the floor where the dry fire water pipe is located is to consider that the flame generally spreads upwards. The heat-sensitive soluble element is actuated by the high temperature of the fire layer, and then the electromagnetic valve switch of the upper floor is activated, which plays a certain pre-spraying function.

[0019] The dry fire-fighting pipe with a number of water spray holes is installed within the insulation layer and does not exceed the scope of the decorative layer.

[0020] The gap between the casing and the water supply pipe is tightly sealed with sealing materials, such as sealants.

[0021] Working process: When a fire breaks out on the exterior wall of a building, the high temperature of the flame triggers the pre-buried thermosensitive soluble element, which then activates the solenoid valve switch through the wire. After the solenoid valve switch is turned on, the water from the water supply pipe immediately enters the dry fire-fighting pipe and flows downstream along the water spray trajectory through the water spray hole.

[0022] When the solenoid valve switch is turned on, the start signal will be fed back to the fire control room, so that the management personnel in the fire control room can take corresponding disposal measures, such as closing the water supply to the dry fire pipe after the fire is extinguished.

[0023] The present utility model is not limited to the above-mentioned implementation modes. Any other products identical or similar to the present utility model derived by anyone under the inspiration of the present utility model shall fall within the protection scope of the present utility model.
