Description

Technical Field

[0001] The utility model generally relates to the field of fire fighting technology. Specifically, it relates to a rescue hose installation structure and a fire fighting system. Background Art

[0002] In the event of a fire in an existing residential building, the elevator will be prohibited from use. Or in some multi-storey buildings in old and dilapidated communities, there is no elevator. When fire extinguishing is required in these civilian residences, the high-rise hoses are laid by manually winding along the evacuation stairs or laid vertically. After reaching the designated floor, the laid hose is connected to the water outlet of the foam aerial fire truck on the first floor, and the fire extinguishing agent reaches the fire extinguishing point on the designated floor through the laid hose for fire extinguishing. Taking a 10-story building as an example, at least 2 reels of hoses are required for fire extinguishing. When the fire brigade arrives at the scene, the firefighters need to climb the stairs on foot, while carrying protective clothing and gas cylinders weighing up to a hundred kilograms, and also holding two to three reels of hoses weighing about 12 - 18 kilograms in their hands. For firefighters, the whole process of laying the hose will consume a great deal of physical strength, which will affect their physical strength distribution in subsequent rescue operations.

[0003] There is a platform two-way water outlet at the top of the boom of an existing aerial platform fire truck or a ladder truck. By additionally connecting a hose, the fire extinguishing agent can be sent to the window of the designated fire extinguishing point on the high-rise building, which can save the climbing time and physical strength of firefighters. However, the fire situation on the floor is complex. The existing aerial platform fire truck can only provide one liquid supply channel. If there are multiple fires, other liquid supply water pipes need to be provided for fire extinguishing, which wastes the physical strength of firefighters and affects the rescue efficiency.

[0052] Now, the exemplary embodiments will be described more fully with reference to the accompanying drawings. However, the exemplary embodiments can be implemented in various forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present utility model will be thorough and complete and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the figures denote the same or similar structures, and thus their detailed descriptions will be omitted.

[0053] This embodiment provides a rescue hose installation structure for laying and installing a rescue hose, such as Figures 1 - 2As shown in the figure, the rescue hose installation structure includes a lifting structure 1, which is configured to carry the rescue hose and can drive the rescue hose to lift vertically, so that the rescue hose extends vertically.

[0054] Among them, the lifting structure 1 can directly drive the disk-shaped rescue hose to rise to a preset position, and then unfold the disk-shaped rescue hose, so that the rescue hose extends vertically, that is, parallel to the outer surface of the building to be rescued. One end of the unfolded rescue hose is fixed by the lifting structure 1, and the other end is connected to the water tank 102 or foam tank of the aerial fire truck 100 for rescue spraying. It can also be that the disk-shaped rescue hose has been unfolded on the ground, and the lifting structure 1 drives one end of the unfolded rescue hose to rise to a preset position, and the rescue hose hangs naturally. If the height of the building to be rescued is relatively high, according to the use needs, multiple disks of rescue hoses can also be unfolded and butted, and then the lifting structure 1 drives one end of the rescue hose to rise to a preset position.

[0055] The rescue hose installation structure provided in this embodiment uses the lifting structure 1 to drive the rescue hose to lift vertically, reducing the physical consumption of rescue personnel, and the laying speed of the rescue hose is relatively fast, which is conducive to the physical distribution of rescue personnel in the subsequent rescue process and improves the rescue efficiency.

[0056] It can be understood that the lifting structure 1 can hoist one or more rescue hoses, and multiple rescue hoses can transport fire extinguishing agents at the same time to achieve the rescue effect of multiple channels and reduce the situation of insufficient fire extinguishing agent supply.

[0057] After the rescue hose is laid, if pressurized water is injected, the rescue hose may swing greatly, which is not conducive to safe rescue.

[0058] For this reason, as Figures 3 - 4 shown, the rescue hose installation structure provided in this embodiment further includes a fixing structure 2, and the fixing structure 2 is respectively detachably connected to the rescue hose and the fixing part of the building to be rescued. Among them, the fixing part of the building to be rescued can be the outer wall of the building to be rescued, an air conditioner bracket, a drain pipe or any other fixable position of the building to be rescued.

[0059] After the rescue hose is laid, the fixing structure 2 is used to fix the rescue hose, reducing the situation of the rescue hose shaking in the air. Since the extending direction of the unfolded rescue hose is the same as the extending direction of the outer surface of the building to be rescued, that is, the unfolded rescue hose extends along the height direction of the building to be rescued, fixing the rescue hose to the building to be rescued through the fixing structure 2 has good reliability and reduces risks such as swinging. At the same time, the connection between the fixing structure 2 and the rescue hose and between the fixing structure 2 and the building to be rescued is not a completely fixed connection, but a movable connection, which is convenient for the installation and disassembly of the rescue hose and saves maintenance costs.

[0060] The rescue hose installation structure provided in this embodiment, under the combined action of the lifting structure 1 and the fixing structure 2, combines the actual situation of the building to be rescued, uses the building to be rescued as the fixing point for fixing the rescue hose, makes use of local materials, can quickly build a conveying channel for transporting fire extinguishing agents, and can simply and effectively achieve the fire extinguishing function.

[0061] In one embodiment, as Figures 1 - 2 shown, the lifting structure 1 includes a working bucket 12 and a telescopic boom 11. One end of the telescopic boom 11 is rotatably connected to the chassis of the aerial fire truck 100, and the other end is rotatably connected to the working bucket 12. The working bucket 12 is used to carry the rescue hose, and the telescopic boom 11 can drive the rescue hose to move up and down in the vertical direction through the working bucket 12.

[0062] Since the telescopic boom 11 of the aerial fire truck 100 has a lifting function, the telescopic boom 11 of the aerial fire truck 100 is used to achieve a rapid lifting function, thereby realizing the transportation of the rescue hose during high-rise fire fighting. By making full use of the structure of the existing aerial fire truck 100, while realizing the lifting and lowering of the rescue hose, the rescue cost can also be saved.

[0063] In one embodiment, the lifting structure 1 further includes a lifting member 13. The lifting member 13 is disposed on the working bucket 12 and is detachably connected to the rescue hose for winding and unwinding the rescue hose.

[0064] Among them, the lifting member 13 is at least one of an electric hoist and a hydraulic winch. The lifting member 13 is small in volume and convenient to install. By installing the lifting member 13 on the working bucket 12, a heavy object within 150 kg can be lifted. For example, a single rescue hose or multiple rescue hoses can be lifted, and other rescue tools such as hydraulic calipers and gas cylinders can also be lifted. The rising and falling speeds of the lifting member 13 are relatively fast, and the rescue hose can be laid in the vertical direction within a short time, realizing motorized transportation, shortening the laying time of the rescue hose, and saving the physical strength of rescue personnel.

[0065] In one embodiment, as Figure 3 shown, the fixing structure 2 includes a first fixing member 21. One end of the first fixing member 21 is detachably connected to the upper end of the rescue hose in the vertical direction, and the other end is detachably connected to a fixed position of the building to be rescued.

[0066] Since the upper end of the rescue hose needs to bear the pressure of the entire rescue hose, by using the first fixing member 21, the upper end of the rescue hose is fixed to a fixed position of the building to be rescued, improving the fixing effect of the entire rescue hose and facilitating rescue personnel to use the rescue hose to carry out rescue work.

[0067] Since there may be a certain distance between the fixed position of the building to be rescued and the upper end of the rescue hose, the first fixing member 21 includes an intermediate connecting portion 211, which has a certain length and is used to compensate for the distance between the fixed position of the building to be rescued and the rescue hose. The intermediate connecting portion 211 is made of a flexible material, that is, the intermediate connecting portion 211 can be straightened, bent, and deformed to meet different usage scenarios.

[0068] Specifically, Figure 3 As shown, the first fixing member 21 also includes two sub-connecting parts 212, which are arranged at both ends of the middle connecting part 211, one of the two sub-connecting parts 212 is detachably connected to the rescue hose, and the other is detachably connected to a fixed position of the building to be rescued.

[0069] Among them, the sub-connection part 212 can be a fixed hook, which is directly hooked on the rescue hose and various fixed pipes or fixed brackets of the building to be rescued; the sub-connection part 212 can also be a buckle, which can specifically be a ring with a pressing function.

[0070] Specifically, one end of the middle connection part 211 is wound around the upper end of the rescue hose and hooked on the middle connection part 211 through one of the sub-connection parts 212, and the other end of the middle connection part 211 is wound around a fixed position of the building to be rescued and hooked on the middle connection part 211 through another sub-connection part 212. The sub-connection part 212 is equivalent to forming a knot. As the gravity of the rescue hose increases, the knot will also be locked more tightly and firmly, thereby increasing the fixing effect between the rescue hose and the building to be rescued. When disassembly is required, the sub-connection part 212 is disassembled from the middle connection part 211, so that the rescue hose and the building to be rescued can be separated.

[0071] In one embodiment, Figure 4 As shown, the fixing structure 2 includes a second fixing member 22, one end of which is detachably connected to the middle of the rescue hose in the vertical direction, and the other end of which is detachably connected to a fixed position of the building to be rescued.

[0072] Since the middle part of the rescue water hose is easily suspended in the air with the building to be rescued and may shake greatly, the middle part of the rescue water hose is fixed to a fixed position of the building to be rescued by using the second fixing member 22, thereby reducing the swing of the rescue water hose, improving the fixing effect of the entire rescue water hose, and making it easier for rescue personnel to use the rescue water hose to carry out rescue work.

[0073] Since there may be a certain distance between the fixed position of the building to be rescued and the middle part of the rescue hose, the second fixing member 22 includes an extension part 221. The extension part 221 has a certain length and is used to compensate for the distance between the fixed position of the building to be rescued and the middle part of the rescue hose. The extension part 221 is made of a flexible material, for example, a nylon belt, etc. The extension part 221 can be straightened and bent, and the middle connection part 211 can be deformed to meet different usage scenarios.

[0074] In one embodiment, the second fixing member 22 further includes a first fixing part 222. The first fixing part 222 is arranged at one end of the extension part 221. The first fixing part 222 is provided with a clamping groove 2221, and the clamping groove 2221 is used for selectively clamping the rescue hose, and the clamping groove 2221 plays a role in limiting the rescue hose.

[0075] Specifically, the first fixing part 222 is a semi-closed structure. The first fixing part 222 has an open end and a cavity. The open end and the cavity communicate to form the clamping groove 2221. The rescue hose enters the cavity through the open end. While the cavity can accommodate the rescue hose, it can also prevent the rescue hose from coming out.

[0076] Specifically, the first fixing part 222 can be formed by bending a wire or the like multiple times. The production process is simple, the production cost is low, and it has a certain elasticity, which is convenient for the rescue hose to enter or come out of the clamping groove 2221.

[0077] In one embodiment, the second fixing member 22 further includes a second fixing part 223. One end of the second fixing part 223 is connected to the end of the extension part 221 far from the first fixing part 222, and the other end of the second fixing part 223 is provided with a hook 2231. The hook 2231 is used for selectively connecting to the fixed position of the building to be rescued.

[0078] Specifically, one end of the second fixing part 223 is a triangular structure. The end of the nylon belt is folded to form a through hole, and one side of the triangular structure passes through the through hole. The triangular structure has the advantage of stable structure. The other end of the second fixing part 223 is provided with a hook 2231, and the hook 2231 can be hooked on the fixed position of the building to be rescued, playing a role in limiting the rescue hose and preventing the rescue hose from having a large position deviation.

[0079] It can be understood that the specific structures of the first fixing member 21 and the second fixing member 22 in this embodiment are not limited. As long as the fixation of the upper end and the middle part of the rescue hose can be realized, it is within the protection scope of this embodiment. However, the fixation tightness of the first fixing member 21 to the upper end of the rescue hose is greater than the fixation tightness of the second fixing member 22 to the middle part of the rescue hose.

[0080] Such as Figures 5 - 9As shown in the figure, this embodiment also provides a fire protection system, which includes an aerial ladder fire truck 100, a foam fire truck 104, and the above-mentioned rescue hose installation structure. The foam fire truck 104 includes a water tank 102, and one end of the rescue hose away from the lifting structure 1 is connected to the water tank 102.

[0081] When the fire department goes out for fire fighting, it generally goes out as a team. In most cases, it will not send out only one vehicle. At least one aerial ladder fire truck 100 will be sent out for aerial rescue or building a fire fighting passage, and then one foam fire truck 104 will be sent out to supply liquid to the aerial ladder fire truck 100.

[0082] For the fire protection structure provided in this embodiment, after the rescue hose is laid using the rescue hose installation structure, the rescue personnel connect the water outlet of the water tank 102 to the water inlet of one end of the rescue hose away from the lifting structure 1, and the rescue personnel can carry out water spraying and fire fighting operations at the fire point of the high-rise fire.

[0083] As Figure 6 shown in the figure, when the aerial ladder fire truck 100 is driving in an old community, generally large aerial ladder fire trucks 100 (with chassis such as 10×4, 8×4 or 6×4, etc.) are not applicable. Although the foam aerial ladder fire truck with a common 4×2 chassis can enter for rescue, it does not have a telescopic boom 11 and thus does not have the function of a lifting vehicle. However, the 32-meter aerial platform aerial ladder fire truck with a 4×2 chassis has the advantages of a small turning radius and good maneuverability, and is more practical to achieve the above fire fighting functions. The turning radius R of this aerial ladder fire truck 100 is only 9.25 meters, the lifting height L can reach up to 32 meters at most, and the maximum working amplitude B is 16 meters, which can meet the requirements of passing through narrow roads in old communities and large-scale rescue work.
