Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, and more specifically, to a fire exhaust water gun. Background Technology

[0002] High temperatures and dense smoke at fire scenes are among the main factors hindering rescue operations and threatening the lives of trapped personnel. Timely and effective smoke removal is crucial for controlling the spread of fire and ensuring unobstructed rescue routes. Current fire-fighting smoke removal operations often require the use of water jets or high-pressure gas to disperse dense smoke. Some water jets integrate window-breaking functions for rapid entry into enclosed spaces; however, even after breaking a window, the water jet still needs to be manually held or secured with a simple support to maintain continuous smoke removal operations.

[0003] Currently, traditional fire exhaust nozzles suffer from insufficient stability: on the one hand, after a window is broken, there is a lack of a dedicated adjustment and fixing structure to accommodate different window thicknesses (such as differences in the thickness of window glass and frames in different buildings). When relying on manual support, the nozzle is prone to shaking due to physical exertion, affecting the direction and efficiency of smoke exhaust. On the other hand, some simple fixing brackets are complicated to adjust and operate, making it difficult to quickly adapt to the site environment. They may even cause the nozzle to tip over due to instability, increasing the safety risks for rescuers and hindering the overall rescue progress. Utility Model Content

[0004] In view of the problems in the related technologies, this utility model proposes a fire exhaust water gun to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows:

[0006] A fire exhaust water gun includes a pipe structure, a sliding structure connected to the pipe structure, a stop structure rotatably connected to the sliding structure, and a limit structure connected to the sliding structure. The limit structure, the stop structure, and the sliding structure constitute a water gun mounting and fixing device. The pipe structure can be adjusted and fixed according to the thickness of the window frame through the fixing device.

[0007] Furthermore, the pipe structure includes a connecting pipe, a shut-off valve, a connecting end, a connecting pipe, a bend section, a limiting guide rod, a U-shaped pipe, a window-breaking spike, a water gun nozzle, and an auxiliary nozzle. The bottom end of the connecting pipe is provided with a connecting end, and a shut-off valve is installed on the connecting pipe. The top end of the connecting pipe is connected to a connecting pipe. The connecting pipe is connected to a bend section through the connecting pipe. A limiting guide rod is fixedly installed on the pipe body of the bend section. One end of the bend section is connected to a U-shaped pipe. A window-breaking spike is fixedly installed on one side of the U-shaped pipe. An auxiliary nozzle is connected to the bend of the U-shaped pipe. The end of the U-shaped pipe is connected to a water gun nozzle.

[0008] Furthermore, the sliding structure includes a sliding ring, a limiting end, and a limiting groove. The two ends of the sliding ring are fixedly provided with limiting ends, and the inner ring of the sliding ring is provided with a limiting groove. The limiting groove fits with the limiting guide rod, and the sliding ring is slidably connected to the limiting guide rod of the bend section through the limiting groove.

[0009] Furthermore, the stop bar structure includes a rotating ring, a friction ring, and a blocking rod. The friction ring is integrally provided on one side of the rotating ring, and the blocking rod is fixedly connected to the ring body of the rotating ring. The rotating ring is rotatably connected to the ring body of the sliding ring.

[0010] Furthermore, the limiting structure includes a fixed ring, a friction metal strip, a connecting ring, a limiting ring, and an open section. The inner ring of the fixed ring has a connecting ring, and one side of the fixed ring has an integrally formed limiting ring. The bottom end of the limiting ring has an open section, and the open section is fitted with a friction metal strip. The friction metal strip is wrapped around the friction ring of the stop bar structure. The fixed ring is fixedly installed on the ring body of the sliding ring through the connecting ring. The limiting ring is in contact with the friction metal strip, and one side of the limiting ring is in sliding contact with one side of the rotating ring.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. By sliding along the limiting guide rod of the tube structure through the sliding structure, and by adjusting the angle of the stop rod in combination with the limiting structure, it can flexibly adapt to different window thicknesses, so as to achieve stable hanging of the water gun on the window wall after the window is broken, and solve the problems of unstable fixing and easy displacement of traditional water guns.

[0013] 2. Pulling the friction metal strip of the limiting structure can drive the stop bar to rotate through static friction, quickly adjusting the engagement angle without the need for additional tools, reducing the difficulty of operation for rescue personnel and improving the speed of on-site response;

[0014] 3. The pipe structure integrates window-breaking spikes and main and auxiliary nozzles, which have the functions of breaking windows, exhausting smoke and extinguishing fires, reducing the number of rescue equipment carried, optimizing the rescue process and improving operational efficiency.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] According to an embodiment of the present invention, a fire-fighting smoke exhaust nozzle is provided.

[0026] like Figure 1-6 As shown, the fire exhaust water gun according to an embodiment of the present utility model includes a pipe structure 1, a sliding structure 4 connected to the pipe structure 1, a stop bar structure 3 rotatably connected to the sliding structure 4, and a limiting structure 2 connected to the sliding structure 4. The limiting structure 2, the stop bar structure 3, and the sliding structure 4 form a water gun mounting and fixing device. The pipe structure 1 can be adjusted and fixed according to the thickness of the window through the fixing device.

[0027] The pipe structure 1 includes a connecting pipe 101, a shut-off valve 102, a docking end 103, a connecting pipe 104, a bend section 105, a limiting guide rod 106, a U-shaped pipe 107, a window-breaking spike 108, a water gun nozzle 109, and an auxiliary nozzle 110. The bottom end of the connecting pipe 101 is provided with a docking end 103. The shut-off valve 102 is installed on the connecting pipe 101. The top end of the connecting pipe 101 is connected to the connecting pipe 104. The connecting pipe 101 is connected to the bend section 105 through the connecting pipe 104. The limiting guide rod 106 is fixedly provided on the pipe body of the bend section 105. One end of the bend section 105 is connected to the U-shaped pipe 107. The window-breaking spike 108 is fixedly provided on one side of the pipe body of the U-shaped pipe 107. The bend of the U-shaped pipe 107 is connected to the auxiliary nozzle 110. The end of the U-shaped pipe 107 is connected to the water gun nozzle 109.

[0028] The pipe structure 1 serves as the main body of the fire-fighting smoke exhaust nozzle, undertaking the functions of water flow transmission, window breaking operation, and smoke exhaust and fire extinguishing. Its bottom docking end 103 is used to connect to the water source, and the on / off valve 102 controls the water flow. The top end is connected to the bend section 105 through the connecting pipe 104, and the limiting guide rod 106 on the bend section 105 provides a sliding track for the sliding structure 4. The window breaking spike 108 on one side of the U-shaped pipe 107 is used for window breaking operations. The auxiliary nozzle 110 at the bend and the water gun nozzle 109 at the end work together to achieve multi-angle smoke exhaust and fire extinguishing, forming a basic functional framework. At the same time, it is connected to the sliding structure 4 through the limiting guide rod 106, providing an adjustment basis for the fixed device.

[0029] The sliding structure 4 includes a sliding ring 401, a limiting end 402, and a limiting groove 403. The two ends of the sliding ring 401 are fixedly provided with the limiting end 402. The inner ring of the sliding ring 401 is provided with the limiting groove 403. The limiting groove 403 fits with the limiting guide rod 106. The sliding ring 401 is slidably connected to the limiting guide rod 106 of the bent pipe section 105 through the limiting groove 403.

[0030] The sliding structure 4 is the moving adjustment carrier of the fixed device. The sliding ring 401 is slidable by the limiting groove 403 of the inner ring of the sliding ring 401 engaging with the limiting guide rod 106 of the tube structure 1, thereby adapting to different window thicknesses. The limiting ends 402 at both ends of the sliding ring 401 are used to limit the lateral movement of the rotating ring 301. Its ring body also provides a rotation connection point for the stop rod structure 3 and a fixed installation point for the limiting structure 2. Through position adjustment and structural bearing, the limiting structure 2 and the stop rod structure 3 are integrated into a movable fixed component.

[0031] The stop bar structure 3 includes a rotating ring 301, a friction ring 302, and a blocking rod 303. The friction ring 302 is integrally provided on one side of the rotating ring 301. The blocking rod 303 is fixedly connected to the ring body of the rotating ring 301. The rotating ring 301 is rotatably connected to the ring body of the sliding ring 401.

[0032] The baffle structure 3 is rotatably connected to the sliding ring 401 of the sliding structure 4 via the rotating ring 301. The baffle 303 on the ring is used to engage with the window wall to fix the water gun. The friction ring 302 on one side of the rotating ring 301 cooperates with the friction metal strip 202 of the limiting structure 2 to achieve rotation adjustment through static friction. When the friction metal strip 202 is pulled, it drives the friction ring 302 and the rotating ring 301 to rotate, thereby adjusting the angle of the baffle 303 to ensure that it is stably engaged with the window wall and improve the overall stability during smoke exhaust.

[0033] The limiting structure 2 includes a fixed ring 201, a friction metal strip 202, a connecting ring 203, a limiting ring 204, and an open section 205. The connecting ring 203 is provided on the inner ring of the fixed ring 201. The limiting ring 204 is integrally provided on one side of the fixed ring 201. The bottom end of the limiting ring 204 is provided with an open section 205. The friction metal strip 202 is matched with the open section 205. The friction metal strip 202 is wrapped around the friction ring 302 of the stop bar structure 3. The fixed ring 201 is fixedly installed on the ring body of the sliding ring 401 through the connecting ring 203. The limiting ring 204 is in contact with the friction metal strip 202. One side of the limiting ring 204 is in sliding contact with one side of the rotating ring 301.

[0034] The limiting structure 2 is fixed to the sliding ring 401 of the sliding structure 4 via the connecting ring 203 of the fixed ring 201. The limiting ring 204 on one side of the fixed ring 201 slides in contact with the rotating ring 301. The space between the inner ring of the limiting ring 204 and the friction ring 302 is the adjustment space of the friction metal strip 202. The bottom opening section 205 of the limiting ring 204 is the transmission opening of the friction metal strip 202. By pulling the friction metal strip 202, the friction ring 302 and the rotating ring 301 are driven to rotate by static friction, so as to achieve precise adjustment of the angle of the blocking rod 303. Finally, in conjunction with the position adjustment of the sliding structure 4, the fixing device adapts to different window thicknesses and completes the stable hanging of the water gun.

[0035] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0036] The main body of the fire-fighting smoke exhaust nozzle is formed by the pipe structure 1. The nozzle mounting and fixing device, consisting of the limiting structure 2, the stop bar structure 3, and the sliding structure 4, allows the nozzle pipe to be hung on the window wall according to the thickness of the window after the window is broken. At the same time, by pulling the friction metal strip 202 of the limiting structure 2, the friction metal strip 202 drives the friction ring 302 and the rotating ring 301 connected to the sliding ring 401 to rotate through static friction, adjusting the rotation angle of the stop bar 303. This allows the two stop bars 303 to be smoothly engaged with the window wall, improving the stability of the nozzle when exhausting smoke.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
