DETAILED DESCRIPTION

[0026] The preferred embodiments of the utility model are described below in combination with the drawings, and it should be understood that the preferred embodiments described herein are only used to illustrate and explain the utility model, and are not used to limit the utility model.

[0027] As Figures 1 to 4 shown, the high-altitude fire-fighting spraying device described in the embodiment is used for high-rise building fire rescue, and aims to be a device capable of quickly reaching the higher floors of the building and stably and accurately performing fire extinguishing operation. The device mainly comprises a bearing platform 10, a lifting mechanism 20, a high-pressure spray head 30, a liquid supply pipeline 40, a fire extinguishing agent storage device 50 and a pneumatic suction cup 60.

[0028] The bearing platform 10 is the main working platform of the device, which is driven by the lifting mechanism 20 arranged on the top of the building 100. The lifting mechanism 20 can control the bearing platform 10 to ascend or descend in the vertical direction of the outer facade of the building 100, so as to transport the bearing platform 10 and other components thereon to the target floor, i.e. the floor where the fire occurs or the floor where the fire fighting operation is needed. In the embodiment, the bearing platform 10 is preferably made of light weight and high strength aluminum alloy material, so as to reduce the overall weight of the device and reduce the load of the lifting mechanism 20. As shown in Figure 1 Fig. 1, the shape of the bearing platform 10 can be designed as a rectangular basket structure according to actual needs, so as to facilitate the installation and arrangement of other components. In an example, the lifting mechanism 20 is preferably a winch type lifting mechanism arranged on the top of the building 100. The winch (not shown in the figure) is fixedly installed on the top of the building 100, connected with the bearing platform 10 through a steel wire rope, and driven by a motor to control the winding and unwinding of the steel wire rope, so as to drive the bearing platform 10 to ascend or descend along the outer facade of the building 100 vertically and accurately reach the predetermined fire floor.

[0029] The high-pressure spray head 30 is arranged on the bearing platform 10, and the nozzle thereof is arranged towards the outer facade of the building 100, so as to spray the extinguishing agent to the target position. The high-pressure spray head 30 is connected with the extinguishing agent storage device 50 through the liquid supply pipeline 40, and used for spraying the extinguishing agent to the target floor. In the embodiment, the extinguishing agent is water, foam extinguishing agent or dry powder extinguishing agent.

[0030] The pneumatic suction cup 60 is arranged on the bearing platform 10 in a telescopic manner relative to the bearing platform 10, and is configured to be extended and adsorbed on the outer facade of the building 100 by vacuum adsorption before the high-pressure spray head 30 sprays the extinguishing agent. In this way, before the fire fighting operation, the adsorption force generated by the pneumatic suction cup 60 can fix the bearing platform 10 in advance, so as to effectively offset the recoil force generated when the high-pressure spray head 30 sprays the extinguishing agent, and ensure the stability and safety of the device, and provide reliable guarantee for continuous and accurate fire fighting operation.

[0031] In a specific embodiment, the pneumatic suction cup 60 mainly comprises two parts of a suction cup body and a vacuum pump (not shown in the figure), the suction cup body is preferably made of rubber material with good sealing performance and adsorption force, such as silicone rubber or nitrile rubber, etc., and the vacuum pump is arranged on the bearing platform 10 to provide negative pressure for the suction cup body, so that the suction cup body can be firmly adsorbed on the outer facade of the building 100. In order to avoid the adverse effects of high temperature generated by the fire source on the work of the pneumatic suction cup 60, a fireproof cover 61 is arranged on the pneumatic suction cup 60, the caliber of the fireproof cover 61 is larger than the diameter of the suction cup body of the pneumatic suction cup 60, and the purpose is that when the suction cup body is adsorbed on the outer facade of the building 100, the fireproof cover 61 can fully cover and cover the suction cup body and key parts of the pneumatic suction cup 60, forming an effective heat protection barrier, ensuring that the pneumatic suction cup 60 can still work stably and reliably in a high temperature environment, and then ensuring the safe and efficient operation of the whole aerial fire extinguishing spraying device.

[0032] In some embodiments, as shown in Figure 1 、 Figure 2 、 Figure 4 , a multi-degree-of-freedom mechanical arm 70 is arranged on the bearing platform 10, the high-pressure spray head 30 is fixedly installed at the end of the mechanical arm 70, and the nozzle of the high-pressure spray head 30 can adjust the spray angle. Specifically, the mechanical arm 70 can adopt the multi-joint structure of an industrial robot, for example, a serial mechanical arm with three or more rotary joints and / or moving joints. The fire scene is complex, and the fire source point may be located in the corner of the window, the inside of the balcony, etc. difficult to directly reach, through the multi-degree-of-freedom mechanical arm 70, the movement of the high-pressure spray head 30 in the horizontal and vertical directions and the spray angle can be flexibly controlled, without frequent movement of the bearing platform 10, the spray range can be expanded to a larger area, effectively covering multiple fire source points in the same floor, greatly improving the fire extinguishing efficiency, and reducing unnecessary losses.

[0033] In some embodiments, as shown in Figure 1 、 Figure 2As shown, the base 80 is fixedly installed on the top of the building 100, and the pipe reel 90 is arranged on the base 80. The water storage device 50 is a water storage tank fixedly arranged on the base 80. One end of the liquid supply pipeline 40 is connected to the water storage tank through a water supply pump, and the other end is connected to the high-pressure nozzle 30 through the pipe reel 90. The pipe reel 90 has an automatic winding and unwinding function, which can automatically release or retract the liquid supply pipeline 40 according to the lifting of the bearing platform 10, so as to ensure that the liquid supply pipeline 40 is always in a proper tension state and avoid winding or knotting. In actual application, the water storage tank (water storage device 50) is fixedly arranged on the base 80 and is used for storing fire-fighting water. When the building 100 catches fire, the aerial fire injection device is started, the lifting mechanism 20 drives the bearing platform 10 to descend to the target floor, in the descending process, the pipe reel 90 automatically releases the liquid supply pipeline 40, and after reaching the target floor, the pneumatic suction cup 60 fixes the bearing platform 10. The fire-fighting water is transported to the high-pressure nozzle 30 through the liquid supply pipeline 40 to perform fire extinguishing operation. The water source pre-stored in the water storage device 50 can quickly cooperate with the high-pressure nozzle 30 to suppress the spread of fire at the initial stage of fire, and provide sufficient buffer time for the deployment of subsequent fire-fighting forces.

[0034] In some embodiments, a quick connector for connecting an external water source is arranged on the water storage tank. After the quick connector is arranged, the water storage tank can be conveniently and quickly connected to an external water source such as a fire hydrant, so as to timely supplement the fire-fighting water in the water storage tank and ensure the continuity and thoroughness of the fire extinguishing operation.

[0035] In some embodiments, as shown in the drawings, Figures 1 to 4 A telescopic arm 81 is arranged on the base 80 and at least partially protrudes from the facade of the building 100. In the case that there are many protruding balconies or decorative lines on the facade of a high-rise building, the telescopic arm 81 can be used to flexibly avoid the collision of the bearing platform 10 with the protruding structures during the lifting process, so as to ensure the stability and safety of the lifting process and finally reach the target fire floor to perform effective fire extinguishing operation. In this embodiment, as shown in the drawings, Figure 1 The lifting mechanism 20 is a rigid chain lifter installed at the distal end of the telescopic arm 81. Compared with a steel wire structure, the rigid chain has superior rigidity and stability, which can ensure the stability of the high-pressure nozzle 30 during the lifting process and improve the safety of the fire extinguishing operation.

[0036] In some embodiments, as shown in the drawings, Figure 1 , Figure 2As shown, the telescopic arm 81 is provided with two vertically opposite first guide wheels 82 at one end away from the base 80, and the wheel surfaces of the two first guide wheels 82 form a first guide space adapted to the liquid supply pipeline 40; the winding axis of the pipe winder 90 is horizontally arranged, and the telescopic arm 81 is provided with two horizontally opposite second guide wheels 83 at one end close to the base 80, and the wheel surfaces of the two second guide wheels 83 form a second guide space adapted to the liquid supply pipeline 40. By arranging the first guide wheels 82, the friction and wear of the liquid supply pipeline 40 during lifting are effectively reduced, and the service life of the liquid supply pipeline 40 is prolonged. At the same time, the first guide wheels 82 constrain and guide the downward bending movement direction of the liquid supply pipeline 40, avoiding the deviation and distortion of the liquid supply pipeline 40. The horizontally arranged pipe winder 90 can reduce the space occupation of the whole device in the vertical direction, and also facilitates the installation of the pipe winder 90 itself. When the pipe winder 90 is horizontally installed, the pipe outlet direction is usually horizontal. The main function of the second guide wheel 83 is to smoothly transition the movement direction of the liquid supply pipeline 40 from the horizontal direction to the vertical direction guided by the first guide wheel 82, to jointly ensure the stable movement of the liquid supply pipeline 40.

[0037] In some embodiments, as shown in Figure 2 As shown, the base 80 includes a track 84 and a rotating support 85, the track 84 is fixedly arranged on the top of the building 100 and extends along the outer edge of the building 100, the rotating support 85 is movably assembled on the track 84 and is configured to move along the track 84; the proximal end of the telescopic arm 81 is fixedly installed on the rotating support 85. The structure of the base 80 with the track 84 and the rotating support 85 enables the high-altitude fire extinguishing and spraying device to move along the edge of the top of the building 100 during operation, as shown in Figure 3 The rotating ability provided by the rotating support 85 realizes full coverage of all vertical surfaces of the building, improves positioning speed and rescue efficiency, and avoids the complexity and high cost of deploying multiple fixed devices on the top of the building.

[0038] Specifically, as shown in Figure 2 As shown, the rotating support 85 is fixedly provided with a plurality of sliding seats 86 at the bottom, the sliding seats 86 are slidably installed on the track 84, each sliding seat 86 is provided with a roller in contact with the track 84, and the rotating support 85 is provided with a drive motor 87 driving at least one roller to rotate. The rolling friction coefficient is much smaller than the sliding friction coefficient, which significantly reduces the friction resistance of the rotating support 85 when moving on the track 84, making the horizontal movement of the rotating support 85 more convenient, smooth and stable.

[0039] In some embodiments, as shown in Figures 1 to 4As shown, the bearing platform 10 is a basket structure, and two vertically parallel scissors guiding mechanisms 11 are arranged on the basket structure, one end of each of the scissors guiding mechanisms 11 is fixed to the bottom of the basket structure, and the other end is fixed to the distal end of the telescopic arm 81. The scissors guiding mechanism 11 is composed of a plurality of cross connecting rods, forming a telescopic parallelogram structure. When the basket structure is subjected to a lateral force, the scissors guiding mechanism 11 can resist lateral deformation and limit the swing amplitude of the basket structure, thereby improving the stability thereof, ensuring the efficiency and safety of fire extinguishing operation even under complex weather conditions or building structure conditions, and avoiding the decrease of spraying precision or the increase of safety risk caused by platform shaking.

[0040] In some embodiments, the depth of the basket structure is greater than the maximum height of the scissors guiding mechanism 11 in the fully retracted state. When the device is in a standby state for a long time, in combination with the use of the rotary support 85, the bearing platform 10 can be rotated to the top of the building, and the scissors guiding mechanism 11 can be stored in the basket, so that the mechanism can be better protected from wind, sun, rain and other natural environment, thereby prolonging the service life of the mechanism and reducing the maintenance cost.

[0041] The high-altitude fire extinguishing spraying device provided by the embodiment realizes rapid response and efficient extinguishing of high-rise building fire by integrating the high-pressure nozzle on the bearing platform which can move vertically along the building facade, and is firmly fixed to the building facade by the pneumatic suction cup, thereby effectively offsetting the recoil force generated when the high-pressure nozzle sprays the fire extinguishing agent, and ensuring the stability and safety of the device.
