High-class hotels, important office buildings, commercial buildings, exhibition buildings, comprehensive buildings of Class I buildings, etc. and other high-rise buildings with a building height exceeding 100m should be equipped with fire hose reels, and their water consumption can be not included in the total fire water consumption. The spacing of the fire hose reels should ensure that a stream of water can reach any part of the indoor ground. The installation height of the fire hose reels should be convenient for use, with flexible movement and no jamming. After the fire hose reels are used, they need to be retracted in time.

[0029] In order to enable those skilled in the art to better understand the present utility model, the technical solutions of the present utility model will be further described below with reference to the accompanying drawings and embodiments.

[0030] As shown in Figures 1-6As shown in the figure, a fire hose reel that can be automatically wound up according to the present utility model includes a fire hose reel outer box 1 connected to a fire protection machine box. Circular switch doors 2 and rectangular blocks 3 are respectively connected to two adjacent sides of the fire hose reel outer box 1. A winding motor 4 is connected to one side of the fire hose reel outer box 1. The output end of the winding motor 4 is connected to a winding rotating rod 401. The winding rotating rod 401 is rotatably connected to the fire hose reel outer box 1. Anti-detachment discs 4011 are connected to both ends of the winding rotating rod 401. The rectangular block 3 is provided with a rectangular through groove 301. The rectangular block 3 is connected to an automatic moving mechanism 5. The automatic moving mechanism 5 is connected to a rectangular moving block 6. The rectangular moving block 6 is slidably connected in the rectangular through groove 301. The rectangular moving block 6 is provided with a circular through groove 601. A matching plastic anti-abrasion cylinder 6011 is connected to the circular through groove 601. A fire hose 7 is slidably connected to the plastic anti-abrasion cylinder 6011.

[0031] In the embodiment of this case, when the staff needs to use the fire hose 7, the winding motor 4 is turned on through the controller. The winding motor 4 drives the winding rotating rod 401 to rotate. While the winding rotating rod 401 rotates, the staff pulls the nozzle part of the fire hose 7 for use. After use, the staff turns on the winding motor 4 and the automatic moving mechanism 5 through the central controller. The winding motor 4 rotates to drive the winding rotating rod 401 to rotate to wind up the fire hose 7. At the same time, during the winding process of the fire hose 7, the automatic moving mechanism 5 drives the rectangular moving block 6 to move reciprocally, which can prevent the fire hose 7 from accumulating at the same position for a long time. Such a structural design can automatically wind the fire hose 7 evenly around the outer wall of the shaft body of the winding rotating rod 401, which is convenient for later use, increases the length of the fire hose 7 that can be stacked in the fire hose reel outer box 1, saves time and effort, is simple to operate, and has high winding efficiency.

[0032] Among them, the fire hose reel outer box 1 has a protective effect on the fire hose 7 against dust, sun protection and damage. Opening and closing the circular switch door 2 on one side of the fire hose reel outer box 1 can facilitate later maintenance of internal components. The plastic anti-abrasion cylinder 6011 connected to the circular through groove 601 can reduce the wear of the fire hose 7 during extraction and winding, and extend its service life.

[0033] Preferably, a rotating block 1001 is connected to one side of the fire hose reel outer box 1. A rotating rod 1002 is connected to the rotating block 1001. The lower end of the rotating rod 1002 is rotatably connected to a mounting plate 1003. A vertical mounting plate 1004 is fixedly connected to the mounting plate 1003. Both ends of the vertical mounting plate 1004 are respectively connected to the inner wall of the fire protection machine box through a plurality of first bolts 1005. Such a structural design can facilitate the automatic adjustment of the direction of the fire hose reel outer box 1 and its connected components, and is convenient for the staff to use the fire hose 7 flexibly in different directions. In fact, other structural shapes that are convenient for automatically adjusting the direction of the fire hose reel outer box 1 can also be considered according to specific situations.

[0034] Preferably, the outer box 1 of the fire hose reel is provided with an installation groove adapted to plug and connect the circular switch door 2. A sealing plug 201 is provided on one side of the circular switch door 2. A plurality of second bolts 202 are connected between the circular switch door 2 and the installation groove of the outer box 1 of the fire hose reel. Such a structural design can facilitate the installation and disassembly of the circular switch door 2 for subsequent maintenance, and at the same time enhance the sealing performance of the circular switch door 2. In fact, other structural shapes that facilitate the installation and disassembly of the circular switch door 2 can also be specifically considered according to specific circumstances.

[0035] Preferably, the automatic moving mechanism 5 includes an adjustment motor 501. The output end of the adjustment motor 501 is connected to a threaded rod 502. The threaded rod 502 is connected to a matching nut sleeve 503. The nut sleeve 503 is connected to a dovetail slider 504. The rectangular block 3 is provided with a dovetail chute 3001 adapted to the sliding of the dovetail slider 504. The upper side of the dovetail slider 504 is connected to the rectangular moving block 6. Such a structural design can achieve the effect of automatically driving the rectangular moving block 6 to move left and right. In fact, other structural shapes that can automatically drive the rectangular moving block 6 to move left and right can also be specifically considered according to specific circumstances. In the embodiment of this case, when the adjustment motor 501 is turned on, the adjustment motor 501 drives the threaded rod 502 at the output end to rotate. When the threaded rod 502 rotates, it drives the nut sleeve 503 to move. When the nut sleeve 503 moves, it drives the dovetail slider 504 to reciprocate in the dovetail chute 3001. When the dovetail slider 504 moves, it drives the rectangular moving block 6 to reciprocate accordingly.

[0036] Preferably, the upper side of the rectangular moving block 6 is connected with a slider 602. The rectangular block 3 is provided with a chute adapted to the sliding of the slider 602. The chute is provided with a guide rod 3002. The slider 602 is slidably connected to the guide rod 3002. Such a structural design can enhance the stability of the rectangular moving block 6 when it moves. In fact, other structural shapes that can enhance the stability of the moving state of the rectangular moving block 6 can also be specifically considered according to specific circumstances.

[0037] Preferably, the fire pipeline 7 is connected with a blocking ball 701. Such a structural design can achieve the effect of preventing the over-winding of the fire pipeline 7 from affecting the use.
