Description

Technical Field

[0001] This utility model relates to the field of fire hose technology, specifically a fire hose with personnel protection function. Background Technology

[0002] A fire hose reel is a device used for extinguishing fires by spraying water or other extinguishing liquids onto the fire source to suppress or extinguish flames. It is typically connected to a fire hose or water source and can effectively control the water flow into different spray patterns to adapt to various firefighting needs. Fire hose reels are crucial tools in firefighting operations and are widely used at various fire scenes.

[0003] Chinese Patent Publication No. CN213609551U discloses "A Fire Hose," aiming to solve the problem in existing technologies where the high water pressure and impact force of fire hoses result in significant recoil, requiring firefighters to expend considerable effort to control them. The fire hose includes a nozzle head and a flow diversion connector for changing the water flow direction, the flow diversion connector being disposed between the nozzle head's outlet and the nozzle tip. In this disclosure, the flow diversion connector changes the direction of the water flow within the connector, thereby reducing the impact force of the water flow on the fire hose, allowing firefighters to control the fire hose with less effort.

[0004] While existing technologies reduce the impact of water flow on fire hoses, they fail to effectively protect firefighters. Furthermore, the high temperature of the flames makes firefighters susceptible to burns, impacting their safety. Additionally, existing technologies are difficult to disassemble, making it difficult to quickly clear blockages in the hoses, which can hinder rescue efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a fire hose with personnel protection function, which solves the problem that the existing technology in the background cannot effectively protect firefighters during use, and the high temperature of the flame makes firefighters easy to be burned by the flame, thus affecting the safety of firefighters. At the same time, the existing technology is difficult to disassemble, which makes it impossible to quickly disassemble the water hose to clear the internal blockage when it occurs. A blocked water hose can affect the efficiency of rescue.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A fire hose with personnel protection function includes a hose body, a protective component is provided in the middle of the hose body, and a separation component is provided on one side of the hose body;

[0008] The protective assembly includes a fixed plate, which is fixedly connected to the outer surface of the gun body near the middle.

A push plate is rotatably sleeved on the side of the multiple connecting rods away from the support rods, and the push plate is slidably sleeved on the outer surface of the gun body. Fireproof cloth is provided on the top of the outer surface of the multiple support rods.

[0009] The separation assembly includes a first connecting plate, which is fixedly connected to one side of the outer surface of the gun body. A first fixing plate is fixedly installed on one side of the outer surface of the first connecting plate, and a column is rotatably embedded inside the first fixing plate. A limit rod is fixedly installed on the side of the column away from the first fixing plate, and a second fixing plate is provided on the outer surface of the column.

[0010] Preferably, a second connecting plate is fixedly installed on one side of the outer surface of the second fixing plate, and a gun head is fixedly installed on the side of the second connecting plate away from the first connecting plate. Multiple fixing rods are slidably embedded inside the limiting rod, and a sliding plate is fixedly installed on the side of each of the multiple fixing rods away from the first connecting plate.

[0011] Preferably, a plurality of return springs are fixedly installed on one side of the outer surface of the slide plate, and the plurality of return springs are all wrapped around the outer surface of the fixing rod, and the side of the plurality of return springs away from the slide plate is fixedly connected to the limiting rod.

[0012] Preferably, the sides of the plurality of fixed rods away from the slide plate are slidably embedded inside the second fixed plate, and the side of the first connecting plate away from the gun body is fixedly installed with an extension tube, which is slidably embedded inside the second connecting plate.

[0013] Preferably, a second sealing ring is provided on the side of the first connecting plate away from the gun body, a first sealing ring is provided on one side of the outer surface of the second connecting plate, and the side of the second connecting plate away from the second fixing plate is rotatably connected to the first connecting plate.

[0014] Preferably, the internal threads of the push plate are fitted with fixed threaded rods, and multiple fixed threaded rods are slidably embedded in the inside of the gun body through the push plate.

[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] Please see Figure 1-4 A fire hose with personnel protection function includes a hose body 1, a protective component is provided in the middle of the hose body 1, and a separation component is provided on one side of the hose body 1.

[0026] The protective assembly includes a fixed plate 2, which is fixedly connected to the outer surface of the gun body 1 near the middle. Multiple support rods 202 are rotatably embedded inside the fixed plate 2, and connecting rods 203 are rotatably embedded on the outer surface of the multiple support rods 202 near the middle. A push plate 204 is rotatably sleeved on the side of the multiple connecting rods 203 away from the support rods 202, and the push plate 204 is slidably sleeved on the outer surface of the gun body 1. Fireproof cloth 201 is provided on the top of the outer surface of the multiple support rods 202.

[0027] The separation assembly includes a first connecting plate 3, which is fixedly connected to one side of the outer surface of the gun body 1. A first fixing plate 301 is fixedly installed on one side of the outer surface of the first connecting plate 3, and a column 303 is rotatably embedded inside the first fixing plate 301. A limit rod 302 is fixedly installed on the side of the column 303 away from the first fixing plate 301, and a second fixing plate 304 is provided on the outer surface of the column 303.

[0028] With the above technical solution, when protection is required, the telescopic protective cover 12 can be pushed towards the side closer to the nozzle 5, so that the telescopic protective cover 12 folds and releases the cover of the fireproof cloth 201. At this time, the push plate 204 can be pushed towards the side closer to the nozzle 5. During the movement of the push plate 204, the connecting rod 203 can be moved. Since the connecting rod 203 is rotatably connected to the support rod 202, the connecting rod 203 can push the support rod 202 during the movement, so that the support rod 202 can drive the fireproof cloth 201 to unfold. The fireproof cloth 201 protects the user and prevents the user from being burned by the flame.

[0029] With the above technical solution, when the device is blocked and needs to be cleaned, the sliding plate 8 can be dragged first. The sliding plate 8 drives the fixed rod 6 to move, so that the fixed rod 6 is separated from the second fixed plate 304 to release the limit on the limiting rod 302. At this time, the limiting rod 302 can be rotated to make the limiting rod 302 vertical. After adjusting the angle of the limiting rod 302, the second fixed plate 304 can be dragged so that the limiting rod 302 slides out from the slot in the second fixed plate 304, thereby separating the first connecting plate 3 from the second connecting plate 4 so that the inside of the device can be cleaned.

[0030] Specifically, a second connecting plate 4 is fixedly installed on one side of the outer surface of the second fixing plate 304, and a gun head 5 is fixedly installed on the side of the second connecting plate 4 away from the first connecting plate 3. Multiple fixing rods 6 are slidably embedded inside the limiting rod 302, and a sliding plate 8 is fixedly installed on the side of the multiple fixing rods 6 away from the first connecting plate 3.

[0031] Through the above technical solution, water is sprayed out through the nozzle 5 for rescue. When necessary, the second connecting plate 4 can be opened to clean the inside of the device. The limiting rod 302 is limited by embedding the fixing rod 6 in the preset fixing hole on the second fixing plate 304, so as to prevent the limiting rod 302 from shifting during use and causing the first connecting plate 3 and the second connecting plate 4 to separate. The drag plate 8 facilitates dragging the fixing rod 6.

[0032] Specifically, multiple return springs 7 are fixedly installed on one side of the outer surface of the slide plate 8, and the multiple return springs 7 are all wrapped around the outer surface of the fixing rod 6. The side of the multiple return springs 7 away from the slide plate 8 is fixedly connected to the limiting rod 302.

[0033] Through the above technical solution, the fixed rod 6 can be automatically reset after being moved by the return spring 7.

[0034] Specifically, multiple fixing rods 6 are slidably embedded inside the second fixing plate 304 on the side away from the slide plate 8, and an extension tube 11 is fixedly installed on the side of the first connecting plate 3 away from the gun body 1, and the extension tube 11 is slidably embedded inside the second connecting plate 4.

[0035] Through the above technical solution, the return spring 7 drives the slide plate 8 to move, which in turn drives the fixing rod 6 to move and embed the fixing rod 6 inside the second fixing plate 304, preventing it from falling off and separating from the second fixing plate 304 during use. The extension tube 11 improves the sealing between the first connecting plate 3 and the second connecting plate 4, preventing water from overflowing from the connection.

[0036] Specifically, a second sealing ring 10 is provided on the side of the first connecting plate 3 away from the gun body 1, a first sealing ring 9 is provided on one side of the outer surface of the second connecting plate 4, and the side of the second connecting plate 4 away from the second fixing plate 304 is rotatably connected to the first connecting plate 3.

[0037] The above technical solution improves the sealing performance of the device by using the first sealing ring 9 and the second sealing ring 10. A connecting shaft is installed at the bottom of the second connecting plate 4. The first connecting plate 3 and the second connecting plate 4 are connected together by rotating the connecting shaft into the rotating block at the bottom of the first connecting plate 3.

[0038] Specifically, the internal threads of the push plate 204 are fitted with fixed threaded rods 13, and multiple fixed threaded rods 13 are slidably embedded in the inside of the gun body 1 through the push plate 204. The inside of the gun body 1 is provided with a limiting groove 14, and the limiting groove 14 is slidably connected to the push plate 204.

[0039] Through the above technical solution, the gun body 1 is provided with multiple limiting holes. By rotating the fixed threaded rod 13, the fixed threaded rod 13 is embedded in the limiting hole to limit the push plate 204. The push plate 204 is provided with a slider. By embedding the slider in the limiting groove 14, the push plate 204 is limited to prevent its position from deviating during use.

[0040] Specifically, a protective plate 15 is fixedly installed on the side of the gun body 1 away from the fixed plate 2, and a telescopic protective cover 12 is provided on the side of the gun body 1 away from the protective plate 15.

[0041] The above technical solution protects the fireproof cloth 201 by using the telescopic protective cover 12 and the protective plate 15 together, thus preventing the fireproof cloth 201 from being damaged when folded.

[0042] In use, when protection is required, the telescopic protective cover 12 can be pushed towards the side closer to the nozzle 5 to fold and release the cover from the fireproof cloth 201. At this time, the push plate 204 can be pushed towards the side closer to the nozzle 5. During the movement of the push plate 204, the connecting rod 203 can be moved. Since the connecting rod 203 is rotatably connected to the support rod 202, the connecting rod 203 can push the support rod 202 during the movement, causing the support rod 202 to unfold the fireproof cloth 201. The fireproof cloth 201 protects the user from burns. When the device is blocked and needs to be cleaned, the sliding plate 8 can be dragged first. The sliding plate 8 moves the fixing rod 6, causing the fixing rod 6 to connect with the fireproof cloth 201. The second fixing plate 304 is separated to release the limiting rod 302. At this time, the limiting rod 302 can be rotated to make it vertical. After adjusting the angle of the limiting rod 302, the second fixing plate 304 can be dragged so that the limiting rod 302 slides out from the slot inside the second fixing plate 304, thus separating the first connecting plate 3 from the second connecting plate 4 for cleaning the inside of the device. After cleaning, the first connecting plate 3 and the second connecting plate 4 can be put together and the limiting rod 302 can be rotated again so that the fixing rod 6 is embedded in the fixing hole reserved on the second fixing plate 304. The second fixing plate 304 is limited and fixed by the limiting rod 302 to prevent the first connecting plate 3 from separating from the second connecting plate 4 during use.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
