AI Technical Summary
Building fires are prone to spread through window glass, resulting in property losses and casualties. It is difficult for existing technology to effectively control the spread of fires.
Design a fire extinguishing structure, including setting up embedded grooves on the window frames of the building's exterior windows, preset steel water pipes and thermally soluble components in the grooves, connecting the water pipes to the water supply system, combining the water sprinkler head and the splashing tray , Thermal-sensitive and soluble components expand and break during a fire, releasing water flow to prevent the flame from spreading.
Effectively control the fire in the room, reduce losses, provide favorable conditions for fire fighting and reduce the spread of the fire to the outside of the building.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of building fire fighting, in particular to a fire extinguishing structure which utilizes building exterior windows to control the spread of fire. Background Art
[0002] Large fires are basically caused by the gradual spread of small fires. Therefore, once a fire occurs, controlling the spread of the fire is the most critical node to reduce fire losses. Take building fires as an example. They usually start from inside a single room, which then causes the window glass outside the room to burst. Then the flames pass through the window and ignite other rooms or even the entire building. This causes significant property losses, and even worse, causes casualties. Therefore, controlling the spread of fire is a very effective way to reduce fire losses. Utility Model Content
[0003] The technical solution adopted by the utility model to solve the above technical problems is:
[0004] A fire extinguishing structure for controlling the spread of fire by using the exterior windows of a building, comprising an exterior wall 1 and a window frame 2 opened on the exterior wall 1, a plurality of embedded grooves 9 are opened on the inner side of the wall of an indoor room 11 above the window frame 2, a steel water pipe 4 is preset at the upper end of the embedded groove 9, a water spray head 6 is arranged inside the embedded groove 9, the upper end of the water spray head 6 is connected to the steel water pipe 4, the lower end of the water spray head 6 is arranged with a heat-sensitive soluble element 7 and a splash plate 8, the steel water pipe 4 is connected to the pipe of the water supply system of the indoor room 11 and is filled with water.
[0005] Preferably, a wooden board 5 is sealed at the lower opening of the embedded groove 9 .
[0006] The beneficial effects of the utility model are: simple structure, strong concealment, simple and convenient construction, which has a favorable effect on controlling the spread of fire on the exterior windows of buildings, controls the fire inside the room within the room and prevents it from spreading outward, and also creates more favorable conditions for firefighters to put out fires, thereby minimizing the losses caused by fire. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 3 It is a schematic diagram of the longitudinal cross-section structure of the embedded groove of the utility model.
[0010] As shown in the figure: 1. Exterior wall; 2. Window frame; 3. Exterior window glass; 4. Steel water pipe; 5. Wooden board; 6. Sprinkler head; 7. Thermosensitive soluble element; 8. Splash plate; 9. Embedded groove; 10. Indoor; 11. Outdoor. DETAILED DESCRIPTION
[0011] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0012] The sprinkler heads with heat-sensitive and soluble elements are evenly installed in the lintel or wall at the top of the window frame of the room. The lower end of the sprinkler head is the heat-sensitive and soluble element for blocking water, and the upper end is connected to the steel water pipe, and the steel water pipe is connected to the pipe of the water supply system in the room and filled with water. Normally, these sprinkler heads are hidden in the embedded grooves of the lintel or wall at the top of the window frame. Once a fire occurs in the room, the outer window glass will generally burst and fall off to form a window hole, and the high-temperature flame will pass through the window frame. When the temperature reaches a certain value, the heat-sensitive and soluble element will expand and rupture, so that the water inside the steel water pipe will be sprayed out through the sprinkler head, impacting the splash plate to form water splashes, and the water splashes fall to form a water curtain to close the entire window hole, thus achieving the purpose of preventing the flame from being inside the room.
[0013] Specifically, if Figure 1 , Figure 2 , Figure 3 As shown, a number of embedded grooves are opened on the inner side of the indoor wall above the window frame of the exterior wall, a steel water pipe is preset at the upper end of the embedded groove, a sprinkler head is arranged inside the embedded groove, the upper end of the sprinkler head is connected with the steel water pipe, a heat-sensitive soluble element and a splash plate are arranged at the lower end of the sprinkler head, and the steel water pipe is connected to the pipe of the indoor water supply system and is filled with water.
[0014] For further concealment and aesthetics, a wooden board is sealed at the lower opening of the embedded groove, and the wall paint consistent with the inner wall can be painted on the outside to play a concealing role. When a fire occurs in the room, the flame burns the wooden board and the temperature reaches a certain value, the heat-sensitive soluble element will expand and rupture, so that the water inside the steel water pipe will be sprayed out through the nozzle and hit the splash plate to form water splashes.
[0015] 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.
