DETAILED DESCRIPTION

[0021] 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.

[0022] As Figures 1 to 4 shown, the high-altitude fire water supply device described in the embodiment is used to supply water for the liftable high pressure spray head 10, aiming to effectively put out the fire of high-rise buildings through the high pressure spray head 10 arranged at the top of the building. The high pressure spray head 10 can be vertically lifted to the fire floor along the outer facade of the building through the lifting mechanism 20.

[0023] In specific implementation, the high pressure spray head 10 is arranged at the distal end (the end away from the fixed base 60) of the cantilever 70 through the lifting mechanism 20. As an implementation manner, the lifting mechanism 20 can be a winch, which is stably installed at the distal end of the cantilever 70 and connected with the high pressure spray head 10 through a high-strength steel wire rope or other flexible connecting piece. The rotation direction and speed of the winch drum are accurately controlled to realize the winding and unwinding of the steel wire rope, and then the lifting of the high pressure spray head 10 is stably controlled. Figure 1 As another optional solution, as

[0024] Specifically, as Figure 1As shown, the water supply device includes a water storage tank 30, a water supply pipe 40 and a pipe reel 50, wherein the water storage tank 30 is arranged on the top of the building through a fixed base 60, the water storage tank 30 is used to store fire-fighting water, the volume of the water storage tank 30 can be flexibly adjusted according to actual needs, so as to ensure that the external water supply system does not need to be excessively relied on when the fire occurs, and the initial fire extinguishing operation can be fully supported by the self-reserved water source, thereby effectively inhibiting the rapid spread of the fire and gaining valuable time for the subsequent gathering of fire fighting forces. The cantilever 70 which is at least partially protruding out of the facade of the building is designed above the fixed base 60, the cantilever 70 is made of high-strength steel material to ensure that it has excellent bearing capacity and bending resistance, and can reliably support the entire water supply and lifting mechanism. The pipe reel 50 is installed at the proximal end of the cantilever 70, which is mainly used to receive and release the water supply pipe 40. One end of the water supply pipe 40 is connected with the water storage tank 30 through a water supply pump 80, the other end of the water supply pipe 40 passes through the pipe reel 50, and finally connects with the high-pressure spray head 10 arranged at the distal end of the cantilever 70. In this embodiment, the nozzle of the high-pressure spray head 10 can spray strong high-pressure water flow to achieve rapid and effective extinguishing of the fire.

[0025] In this way, by automatically adjusting the length of the water supply pipe 40 through the pipe reel 50 according to the lifting position of the high-pressure spray head 10, that is, by automatically winding and unwinding the water supply pipe 40, it is ensured that the length of the water supply pipe 40 always matches the position of the spray head, thereby effectively avoiding problems such as winding, knotting or excessive stretching of the water supply pipe 40 during lifting, and significantly improving the continuity, stability and safety of water supply.

[0026] In some embodiments, as shown in Figure 1 , Figure 3 , Figure 4 As shown, the distal end of the cantilever 70 away from the fixed base 60 is provided with two first guide wheels 61 arranged vertically opposite to each other, and a first guide space adapted to the water supply pipe 40 is formed between the wheel surfaces of the two first guide wheels 61. In this embodiment, the first guide wheels 61 are made of wear-resistant nylon material and are connected with the cantilever 70 through rolling bearings to ensure that they rotate flexibly and can smoothly guide the movement of the water supply pipe 40. At the same time, the diameter of the first guide wheels 61 is slightly larger than the diameter of the water supply pipe 40, so that the water supply pipe 40 has a certain gap when passing through the first guide space to avoid excessive extrusion. Specifically, by arranging the first guide wheels 61, the friction and wear of the water supply pipe 40 during lifting are effectively reduced, and the service life of the water supply pipe 40 is prolonged. At the same time, the first guide wheels 61 constrain and guide the movement direction of the downward bending of the water supply pipe 40, thereby avoiding the deviation and distortion of the water supply pipe 40.

[0027] In some embodiments, as shown in Figures 1 to 3As shown, the winding axis of the pipe winder 50 is horizontally arranged, and the cantilever 70 is provided with two horizontally arranged second guide wheels 62 at one end close to the fixed base 60, and the wheel surfaces of the two second guide wheels 62 form a second guide space matched with the water supply pipe 40. The horizontal arrangement of the pipe winder 50 can reduce the space occupation of the whole device in the vertical direction, and also facilitates the installation of the pipe winder 50 itself. When the pipe winder 50 is horizontally installed, the outlet direction of the pipe winder 50 is usually horizontal, and the main function of the second guide wheel 62 is to smoothly transition the movement direction of the water supply pipe 40 from the horizontal direction to the vertical direction guided by the first guide wheel 61, and to jointly ensure the smooth movement of the water supply pipe 40.

[0028] In some embodiments, as shown in Figure 1 、 Figure 3 、 Figure 4 As shown, the cantilever 70 adopts a telescopic design, including a fixed arm 71 and a movable arm 72. The fixed arm 71 is fixedly installed on the fixed base 60, and specifically, the fixed arm 71 is fixedly installed on the fixed base 60 by high-strength bolts or other reliable connection methods, thereby providing stable support for the whole cantilever system. The movable arm 72 is slidably installed on the fixed arm 71 along the length direction of the fixed arm 71, and a hydraulic cylinder 73 for driving the movable arm 72 to move relative to the fixed arm 71 is arranged on the fixed arm 71. Specifically, one end of the hydraulic cylinder 73 is fixed on the fixed arm 71, and the other end is connected with the movable arm 72. When the hydraulic cylinder 73 is extended, the movable arm 72 is pushed to slide outward, thereby increasing the length of the cantilever 70. When the hydraulic cylinder 73 is retracted, the movable arm 72 is pulled to slide inward, thereby reducing the length of the cantilever 70. The stroke of the hydraulic cylinder 73 determines the maximum telescopic range of the movable arm 72.

[0029] In actual application, when a fire occurs at a certain floor of a building, the operator can adjust the extension length of the movable arm 72 through the control system, so that the high-pressure nozzle 10 can accurately aim at the fire location and avoid obstacles on the facade of the building, such as air conditioning units, billboards, etc., so as to expand the coverage range of the high-pressure nozzle 10 and make it adapt to various complex fire scenes.

[0030] Specifically, as shown in Figure 1 、 Figure 4 Specifically, as shown in Figure 1 、 Figure 4 The outer side of the fixed arm 71 is provided with a guide rail 711 extending along the length direction thereof, and the movable arm 72 is provided with a side plate 721 extending downward, and two rows of first rolling elements 722 are pivotally connected to the side plate 721 and are in rolling contact with the upper and lower sides of the guide rail 711, respectively. The guide rail 711 provides a movement track for the movable arm 72, so that the movable arm 72 can only slide along the length direction of the fixed arm 71, and cannot deviate or shake laterally.

[0031] In some embodiments, as shown in Figure 3 The upper surface of the fixed arm 71 is provided with a groove, and a second rolling member 712 is pivoted in the groove and in rolling contact with the lower surface of the movable arm 72.

[0032] In some embodiments, as shown in Figure 3 、 Figure 4 The movable arm 72 is a hollow metal square beam, and the portion of the water supply pipe 40 between the pipe reel 50 and the high-pressure nozzle 10 passes through the movable arm 72 along the length direction of the movable arm 72.

[0033] In some embodiments, as shown in Figure 1 、 Figure 3 A quick connector 90 for connecting an external water source is arranged on the water storage tank.

[0034] The high-altitude fire-fighting water supply device provided in the embodiment utilizes the height advantage of the top of a building to integrate the water storage tank, the pipe reel, the lifting mechanism and the high-pressure nozzle on the fixed base and the cantilever arm that can extend out of the facade of the building, so that the device is compact and efficient.
