Description

Technical Field

[0001] This utility model relates to the field of fire-fighting equipment, and in particular to a fire-fighting smoke exhaust nozzle. Background Technology

[0002] During firefighting and rescue operations, firefighters often encounter indoor spaces filled with dense smoke and toxic gases. To improve visibility at the fire scene, alleviate high temperatures, reduce the harmful effects of toxic gases, effectively control the fire, and improve rescue and firefighting efficiency, firefighters utilize available equipment and employ various smoke extraction methods. Using fire hoses is a commonly used and effective method. The principle of fire hoses is to spray water outwards, accelerating airflow and creating a pressure difference, thereby dispersing the smoke from inside the room and expelling it outside. However, existing fire hoses have limited length and lack fixed installation, making it difficult to extend them from the ground floor to the windowsill of an upper floor for smoke extraction. Utility Model Content

[0003] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a fire smoke exhaust nozzle that can be extended to the upper floor for smoke exhaust and can be fixed to the windowsill for convenient use.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A fire exhaust nozzle, including

[0006] A straight pipe, composed of multiple pipe sections connected by threads, with a hose connector at the bottom of the straight pipe;

[0007] A C-shaped rotary tube is used to extend into the room, and the lower end of the rotary tube is connected to the straight tube.

[0008] The water nozzle is located at the upper end of the rotary pipe, facing the straight pipe.

[0009] A breaking cone is positioned on the side of the rotary tube away from the straight tube;

[0010] A hanging rod is installed on the side of the rotary tube away from the straight tube and below the demolition cone; the hanging rod is used to suspend the tube on the windowsill.

[0011] According to an embodiment of this utility model, a fire exhaust nozzle has at least the following advantages: In use, multiple pipe sections are connected to form a straight pipe according to the floor height. This straight pipe is then connected to a rotary pipe, which is used to lift the rotary pipe, allowing it to extend into the room and be suspended from the windowsill by a hanging rod. This eliminates the need for firefighters to hold it manually. If there is glass on the windowsill, it can be broken with a demolition spike before inserting the nozzle. After installation, the fire hose enters through the hose connector at the bottom of the straight pipe and sprays water outwards through the nozzle on the rotary pipe. This accelerates airflow, creating a pressure difference that disperses the internal smoke outwards, expelling the smoke from the room. Therefore, this fire exhaust nozzle can be extended to upper floors for smoke extraction and can be fixed to a windowsill for convenient use. It should be noted that this fire exhaust nozzle is primarily designed for residential buildings with four floors or less and is not suitable for high-rise buildings.

[0012] According to some embodiments of the present invention, it also includes an extension water gun, which includes an extension tube and an extension nozzle. The extension tube is connected to the top of the rotary tube, and the extension nozzle is connected to the top of the extension tube and faces the straight tube.

[0013] The advantage is that setting up extended water guns and extended nozzles can supplement the water spray nozzles, thereby increasing the range of water sprayed outwards, which is beneficial for exhausting indoor smoke outwards.

[0014] According to some embodiments of the present invention, the extension tube is provided with a rotatable joint that communicates with the top of the rotary tube.

[0015] The advantage is that the rotatable joint allows the extension pipe to be rotated to change the spray angle of the extension nozzle. This can adjust the direction of smoke exhaust, or the extension nozzle can be directed downwards to spray water into the room for cooling and fire extinguishing. This, combined with the smoke exhaust process of the water nozzle, is beneficial for firefighters to carry out fire extinguishing work.

[0016] According to some embodiments of this utility model, the extension tube is provided with a switching valve.

[0017] The advantage is that the on / off valve can be used to shut off the nozzle when it is not needed for operation.

[0018] According to some embodiments of the present invention, a support rod is also included. The support rod is disposed at the bottom of the rotary tube near the side of the straight tube, and the top of the support rod is hinged to the bottom of the rotary tube for cooperating with the straight tube to support the rotary tube.

[0019] The advantage is that by hinged the support rod to the bottom of the rotary tube, both the support rod and the straight tube can be lifted with both hands, which is beneficial for supporting the rotary tube and hanging it on the windowsill.

[0020] According to some embodiments of the present invention, the support rod is composed of multiple sections connected by threads.

[0021] The advantage is that this support rod setup allows for the connection of an appropriate number of sections based on the floor height. Generally, the length of the support rod corresponds to the length of the straight pipe, making it convenient to match the straight pipe.

[0022] According to some embodiments of the present invention, the straight tube is provided with a handle.

[0023] The advantage is that the straight pipe with a handle makes it easy for firefighters to grip and operate.

[0024] According to some embodiments of this utility model, a control valve is provided on the straight pipe.

[0025] The advantage is that the control valve can open or close the water supply to the hose and regulate the water flow rate into the straight pipe.

[0026] According to some embodiments of the present invention, a rubber collar is provided at the top of the hanging rod, and the hanging rod is sleeved on the rotary tube through the rubber collar.

[0027] The advantages are: the rubber collar can prevent the hanging post from moving on the swivel tube, which helps to stably hang the swivel rod on the windowsill, and the position of the hanging rod can also be adjusted according to the thickness of the windowsill wall.

[0028] According to some embodiments of this utility model, the straight tube and the rotary tube are made of aluminum alloy.

[0029] The advantages are: the lightweight aluminum alloy material is easy for firefighters to use, and it is also resistant to corrosion and has a long service life.

[0030] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0041] The following is for reference. Figures 1-4 A fire exhaust nozzle is described in detail with reference to a specific embodiment. It is to be understood that the following description is merely illustrative and not intended to limit the scope of the invention.

[0042] like Figure 1 and Figure 4 As shown, a fire exhaust nozzle includes a straight pipe 100, a rotary pipe 130, a water nozzle 140, a demolition cone 150, and a hanging rod 160.

[0043] The straight pipe 100 is composed of multiple pipe sections 110 connected by threads, and a hose connector 120 is provided at the bottom of the straight pipe 100; the rotary pipe 130 is C-shaped and is used to extend into the room, and the lower end of the rotary pipe 130 is connected to the straight pipe 100; the water nozzle 140 is located at the upper end of the rotary pipe 130 facing the straight pipe 100; the demolition cone 150 is located on the side of the rotary pipe 130 away from the straight pipe 100; the hanging rod 160 is located on the side of the rotary pipe 130 away from the straight pipe 100 and below the demolition cone 150, and the hanging rod 160 is used to hang on the windowsill. In use, multiple pipe sections 110 are connected to form a straight pipe 100 according to the floor height. The straight pipe 100 is then connected to a rotary pipe 130. The rotary pipe 130 is then lifted through the straight pipe 100, allowing it to extend into the room and be suspended from the windowsill by a hanging rod 160. If there is glass on the windowsill, it can be broken first using a breaker cone 150 before the pipe is inserted. After installation, the fire hose enters through the hose connector 120 at the bottom of the straight pipe 100 and sprays water outward through the nozzle 140 of the rotary pipe 130. This accelerates airflow and creates a pressure difference, thereby causing the internal smoke to diffuse outward and expel the smoke from the room. Therefore, this fire exhaust nozzle can be extended to upper floors for smoke extraction and can be fixed to a windowsill for convenient use. It should be noted that this fire exhaust nozzle is mainly for residential buildings with 4 floors or less and is not suitable for high-rise buildings.

[0044] In some embodiments of this utility model, such as Figure 1 and Figure 2As shown, it also includes an extension water gun 170, which includes an extension pipe 180 and an extension nozzle 190. The extension pipe 180 is connected to the top of the rotary pipe 130, and the extension nozzle 190 is connected to the top of the extension pipe 180 and faces the straight pipe 100. The extension water gun 170 and extension nozzle 190 supplement the outlet nozzle 140, thereby increasing the range of water spray and facilitating the exhaust of indoor smoke. Specifically, the extension pipe 180 is equipped with a rotatable connector 200 connected to the top of the rotary pipe 130. The rotatable connector 200 allows the extension pipe 180 to be rotated to change the spray angle of the extension nozzle 190. This allows adjustment of the smoke exhaust direction and also allows the extension nozzle 190 to spray water downwards into the room for cooling and fire extinguishing. This, combined with the smoke exhaust process of the outlet nozzle 140, facilitates firefighters' firefighting efforts. Furthermore, the extension pipe 180 is equipped with a switch valve 210. The switch valve 210 can be used to close the extension nozzle 190 when it is not needed to operate.

[0045] In some embodiments of this utility model, such as Figures 1-3 As shown, it also includes a support rod 220, which is located at the bottom of the rotary tube 130 near the straight tube 100. The top of the support rod 220 is hinged to the bottom of the rotary tube 130 to cooperate with the straight tube 100 and support the rotary tube 130. The hinged connection between the support rod 220 and the bottom of the rotary tube 130 allows both the support rod 220 and the straight tube 100 to be lifted with both hands, facilitating the support of the rotary tube 130 and its hanging on the windowsill. Specifically, the support rod 220 is composed of multiple sections 230 connected by threads. This arrangement allows for the connection of an appropriate number of sections 230 according to the floor height. Generally, the length of the support rod 220 corresponds to the length of the straight tube 100, facilitating its cooperation with the straight tube 100.

[0046] Understandably, the straight pipe 100 is equipped with a handle 240. The handle 240 on the straight pipe 100 facilitates gripping by firefighters and aids in operation. Furthermore, the straight pipe 100 is equipped with a control valve 250. The control valve 250 can open or close the water inlet to the hose and regulate the water flow rate entering the straight pipe 100.

[0047] It should be noted that the top of the hanging rod 160 is equipped with a rubber collar 260, and the hanging rod 160 is fitted onto the rotary tube 130 through the rubber collar 260. The rubber collar 260 can prevent the hanging rod from moving on the rotary tube 130, which is conducive to the stable hanging of the rotary rod on the windowsill, and can also adjust the position of the hanging rod 160 according to the thickness of the windowsill wall.

[0048] It is worth mentioning that the straight pipe 100 and the rotary pipe 130 are made of aluminum alloy. The use of aluminum alloy is lightweight, which is beneficial for firefighters, and it is also resistant to corrosion and has a long service life.
