Description

Technical Field

[0001] This utility model relates to the field of fire-fighting equipment, and in particular to a back-mounted fire hose carrying device. Background Technology

[0002] A key challenge in fighting fires in high-rise buildings is ensuring a stable water supply, particularly for close-quarters firefighting teams. In high-rise buildings, it's difficult to lay fire hoses vertically; instead, a main hose line must be laid winding along the staircases to extinguish the fire. Traditionally, fire hoses are laid by firefighters carrying them by hand, which is extremely physically demanding and restricts their movement, increasing the risk of injury.

[0003] Prior art CN218076117U discloses a portable fire hose carrier combined with an air respirator, consisting of a frame and an adapter. The frame is equipped with a rotating hook and a sliding sleeve, and the rotating hook is equipped with a set screw. The frame is divided into two placement areas: area A is for fire hose placement, and area B is for air respirator placement. The adapter is equipped with four sets of respirator mounting blocks, and existing ready-made air respirator assemblies can be installed as a whole onto the mounting blocks. The frame is hung on the adapter via the rotating hook, and firefighters carry the fire hose carrier on their shoulders for integrated carrying.

[0004] However, existing technologies require attaching the air respirator to the back frame, which is not as practical or convenient as wearing a traditional respirator. At the same time, existing portable hose back frames combined with air respirators cannot reel in the fire hose or control the speed at which the fire hose exits the coil. Utility Model Content

[0005] The purpose of this invention is to provide a back-mounted fire hose carrying device to solve the problems of low practicality and convenience of existing portable hose carriers, as well as the inability to reel in fire hoses and adjust the speed of fire hose exiting the reel.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a back-mounted fire hose carrying device, comprising a fixing component, a winding reel rotatably disposed on both sides of the fixing component for winding the fire hose, and an adjusting component disposed on the fixing component. The fixing component includes a fixing ring for hanging on a breathing apparatus and a support plate for fitting against the waist. The fixing ring and the support plate are connected by a steel plate or steel pipe. Two rotating bearings are symmetrically disposed at the connection between the fixing ring and the support plate. A transmission crankshaft is disposed between the two rotating bearings. The two ends of the transmission crankshaft pass through the rotating bearings and are connected to the winding reels on both sides, for driving the winding reels on both sides to move synchronously.

[0007] Furthermore, it also includes an adjustment assembly, which includes a first transmission wheel fixedly mounted on the transmission crankshaft, a tension adjustment group mounted outside the support plate, a second transmission wheel mounted on the tension adjustment group, and a speed control belt sleeved on the first transmission wheel and the second transmission wheel.

[0008] Furthermore, the tension adjustment assembly includes a fixed nut fixed to the support plate, an adjusting screw threadedly connected to the fixed nut, a transmission wheel seat connecting the adjusting nut and the second transmission wheel, and an adjusting nut threadedly connected to the adjusting screw.

[0009] Furthermore, the support plate is provided with waist-binding straps on both sides for binding around the waist.

[0010] Furthermore, the winding reel includes a support plate, a support frame, and a support column parallel to the support plate and forming a second interval area, wherein the support frame has a first interval area.

[0011] Furthermore, the back-mounted fire hose carrying device also includes a GPS locator and a temperature alarm mounted on the support plate or the steel pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention solves the problems of existing technologies where the hose cannot be directly attached to a breathing apparatus and the hose reel speed is not adjustable. Without affecting the wearing of the breathing apparatus, it can be directly attached to the breathing apparatus via a fixing ring. The structure is simple and easy to operate. Simultaneously, the support plate conforms to the waist, distributing the weight of the entire back-mounted fire hose carrying device to the waist, reducing physical exertion. Furthermore, the reel for winding the fire hose, installed on both sides of the fixing component, allows the fire hose to automatically rotate and exit the reel as the firefighter runs, freeing up their hands during hose laying and improving the firefighter's operability and safety during rescue operations.

[0014] In addition, this utility model is also provided with a means to adjust the rotation speed of the winding reel to prevent the fire hose from exiting the reel too quickly and affecting the laying of the fire hose. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0021] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0022] like Figures 1 to 3As shown, this utility model provides a back-mounted fire hose carrying device. The back-mounted fire hose carrying device includes a fixing component 1, winding reels 2 rotatably disposed on both sides of the fixing component 1 for winding the fire hose, and an adjusting component 3. The fixing component 1 includes a fixing ring 11 for hanging on a breathing apparatus. The fixing ring 11 is a circular ring made of steel pipe and is located between the two winding reels 2. A support plate 12 for fitting against the waist is an arc-shaped plate made of plastic or iron. When the back-mounted fire hose carrying device is hung on the breathing apparatus, the support plate 12 fits against the waist of the user, distributing the weight of the entire device and maintaining balance, thus reducing the physical exertion of firefighters. The fixing ring 11 and the support plate... The 12 are connected by a steel plate 13 or a steel pipe. One end of the steel plate 13 or steel pipe is fixedly connected to both sides of the fixed ring 11, and the other end is connected to the support plate 12 in a triangular shape. The triangular connection can strengthen the overall strength of the device and prevent the steel plate 13 or steel pipe from deforming. Two rotating bearings 14 are symmetrically provided at the connection or corner of the fixed ring 11 and the support plate 12. A transmission crankshaft 15 is provided between the two rotating bearings 14. The two ends of the transmission crankshaft 15 pass through the rotating bearings 14 and are connected to the winding reels 2 on both sides, so as to drive the winding reels 2 on both sides to move synchronously. The adjustment component 3 is provided between the transmission crankshaft 15 and the support plate 12, and is used to adjust the rotation speed of the winding reels 2.

[0023] This invention solves the problems of existing technologies where the hose cannot be directly attached to a breathing apparatus and the hose reel speed is not adjustable. Without affecting the wearing of the breathing apparatus, it can be directly attached to the breathing apparatus via the fixing ring 11. The structure is simple and easy to operate. Simultaneously, the support plate 12 conforms to the waist, distributing the weight of the entire back-mounted fire hose carrying device to the waist, reducing energy consumption. Furthermore, the reel 2 for winding the fire hose, installed on both sides of the fixing component 1, allows the fire hose to automatically rotate and exit the reel as the firefighter runs, freeing up their hands during hose laying and improving the firefighter's operability and safety during rescue operations.

[0024] In order to control the exit speed of the fire hose, an adjustment assembly 3 is provided between the transmission crankshaft 15 and the support plate 12. The adjustment assembly 3 includes a first transmission wheel 31 fixed on the transmission crankshaft 15, a tension adjustment group 32 located outside the support plate 12, a second transmission wheel 33 located on the tension adjustment group 32, and a speed control belt 34 sleeved on the first transmission wheel 31 and the second transmission wheel 33. The first transmission wheel 31 and the second transmission wheel 33 are used to limit the speed control belt 34 to prevent it from deviating. The tension adjustment group 32 includes a fixing nut 321 fixed on the support plate 12, an adjusting screw 322 threadedly connected to the fixing nut 321, a transmission wheel seat 324 connecting the adjusting nut 323 and the second transmission wheel 33, and an adjusting nut 323 threadedly connected to the adjusting screw 322. The fixing nut 321 is fixed on the support plate 12 to form an adjustment fulcrum. The transmission wheel seat 324 is the base of the second transmission wheel 33, ensuring that the second transmission wheel 33 can maintain rotation. By rotating the adjusting nut 323, the adjusting screw 322 can be moved upward or downward. When the adjusting screw moves upward, the distance between the first transmission wheel 31 and the second transmission wheel 33 decreases, the tension on the speed control belt 34 is low, and the restraint on the transmission crankshaft 15 is low. The fast rotation speed of the two reels 2 results in a fast hose reel exit speed, suitable for use in open environments where rapid hose laying is required. When the adjusting nut 323 is turned, the adjusting screw 322 is lowered slightly, increasing the distance between the first drive wheel 31 and the second drive wheel 33. This increases the tension on the speed control belt 34, resulting in greater restraint on the transmission crankshaft 15. Consequently, the slow rotation speed of the two reels 2 and the slow hose reel exit speed make this suitable for use in complex environments where slow hose laying is required. This invention allows for flexible adjustment of the hose reel exit speed according to the actual conditions of the fire scene. Whether it is a need for rapid deployment to cover a large area or slow and precise laying in complex environments to ensure the rationality and safety of hose arrangement, this invention meets the requirements, making firefighting operations smoother and more efficient, and reducing operational delays and resource waste caused by improper hose laying speed.

[0025] To further ensure the carrying stability of the back-mounted fire hose carrying device, the support plate 12 is provided with waist straps 121 on both sides for binding around the waist. The waist straps 121 are elastic bands that can be manually adjusted in tightness and are fastened around the waist by buckles, thus ensuring the carrying stability of the back-mounted fire hose carrying device.

[0026] To ensure the stability of the fire hose connection on the take-up reel 2, the take-up reel 2 includes a support plate 21, a support frame 25, and a support column 22 parallel to the support plate 21 and forming a second interval area 24. The support frame 25 has a first interval area 23. The take-up reel 2 of this invention not only has the function of releasing the fire hose, but also can reel in the fire hose. One end of the fire hose is clamped in the first interval area 23. By rotating the take-up reel 2, the fire hose is reeled into the second interval area 24 between the support frame 20 and the support plate 21. The support plate 21 and the support column 22 ensure that the fire hose will not fall off, solving the problem in the prior art that the fire hose can only be laid but not reeled in.

[0027] To ensure the safety of firefighters, the backpack-mounted fire hose carrying device can also be equipped with a GPS locator 4 and a temperature alarm 5 on the support plate 12 or the steel pipe. The GPS locator 4 can provide the command center and teammates with the firefighter's location information in real time and accurately. This allows for rapid location determination and timely rescue measures during rescue operations, whether encountering sudden dangerous situations requiring emergency rescue or becoming separated from teammates during operations, greatly improving the firefighter's chances of survival in dangerous environments. The temperature alarm 5 can monitor the temperature of the firefighter's surrounding environment in real time. When the temperature exceeds the safety threshold, it will issue an alarm signal in a timely manner, especially in environments where alcohols or hydrogen are burning (the flames of burning alcohols and hydrogen are not visible during the day, making firefighters vulnerable to burns), reminding them to take appropriate protective measures or evacuate the danger zone.

[0028] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
