DETAILED DESCRIPTION

[0013] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0014] like Figure 1-Figure 4As shown, the intelligent indoor fire hydrant box includes a box body 8, a box door 1, a fire hydrant head 7 and a fire hose 10. The box door 1 and the box body 8 are hinged. The box body 8 has a first installation cavity 19 and a second installation cavity 12. The fire hydrant head 7 is located above the first installation cavity 19, and the fire hydrant head 7 has two interfaces 6. Two groups of fire hoses 10 are provided, and joints 5 and water gun heads 14 are respectively provided at both ends of the fire hose 10. The joints 5 are threadedly connected to the interfaces 6. An electric control valve is provided at the front end of the water inlet of the fire hydrant head 7 corresponding to the two interfaces 6. Two first guide rings 4 are fixedly installed on the top of the box body 8. A mounting frame 3 is provided in the first installation cavity 19. A fixing component 2 for keeping the mounting frame 3 in a suspended installation state is provided on the box body 8. The mounting frame 3 is provided with equal intervals along its height direction. A plurality of sliders 25 are provided, and second guide rings 16 are fixedly installed on both sides of the sliders 25. A power assembly for driving the sliders 25 to slide horizontally is provided on the mounting frame 3. The sliding directions of the two adjacent sliders 25 are opposite to each other. A fixing block 33 is provided at the bottom of the first mounting cavity 19. Third guide rings 11 are fixedly installed on both sides of the fixing block 33. The axis lines of the third guide ring 11 and the second guide ring 16 are arranged in parallel. The axis lines of the first guide ring 4 and the second guide ring 16 are arranged vertically. The fire hose 10 passes through the first guide ring 4, the second guide ring 16, the third guide ring 11 and the box body 8 in sequence. A clamping assembly 15 for clamping the water gun head 14 is provided in the second mounting cavity 12. A control panel 9 is provided on the side of the box body 8. The control panel 9 is coupled to the electric control valve.

[0015] The power assembly includes a first motor 17, a first screw rod 24 and a gear 22. The number of the first screw rod 24, the gear 22 and the slider 25 is equal. The first screw rod 24 is rotatably connected to the mounting frame 3, and the first screw rod 24 is threadedly connected to the slider 25. The gear 22 is fixed at the end of the first screw rod 24, and two adjacent gears 22 are meshed for transmission. The output shaft of the first motor 17 is fixedly connected to one of the first screw rods 24. The first motor 17 drives one of the first screw rods 24 to rotate, so that one of the gears 22 rotates synchronously. By relying on the mutual meshing between the gears 22, all the first screw rods 24 can rotate. The rotation directions of the two adjacent first screw rods 24 are opposite, thereby driving the two sliders 25 to slide in opposite directions. In this way, all the second guide rings 16 can slide toward the middle or both sides of the mounting frame 3, so that the length of the fire hose 10 in the box body 8 can be adjusted to prepare for lengthening or storing the fire hose 10.

[0016] The mounting frame 3 is provided with a limiting groove 18 for the second guide ring 16 to slide. The two adjacent limiting grooves 18 are staggered. The limiting groove 18 can limit the sliding distance of the slider 25, so that all the second guide rings 16 can be smoothly arranged in a row at different heights. The first guide ring 4, the second guide ring 16 and the third guide ring 11 can play a guiding and limiting role on the water-filled fire hose 10.

[0017] The fixing assembly 2 is provided with four groups, and includes support columns 26 and fastening bolts 23. The fastening bolts 23 pass through the mounting frame 3 and the support columns 26 and are fixedly connected to the box body 8. The support columns 26 are located between the mounting frame 3 and the box body 8, so that a gap is formed between the two for installing the second guide ring 16, so as to facilitate the installation of two fire hoses 10.

[0018] A mounting block 21 is provided in the middle of the mounting frame 3 in the direction of the extension line of the limit groove 18, and a pressure sensor 20 is provided on the side of the mounting block 21. The pressure sensor 20 is coupled to the electric control valve. When the second guide ring 16 contacts the pressure sensor 20, the pressure sensor 20 outputs an electrical signal indicating that the circuit where the electric control valve is located is closed. Before extinguishing the fire, the first motor 17 drives the first screw 24 to rotate, so that all the sliders 25 slide toward the middle of the mounting frame 3, so that one of the second guide rings 16 contacts the pressure sensor 20, so that the control panel 9 can be operated to energize the electric control valve. At this time, the pressure sensor 20 is equivalent to a switch, which can effectively avoid the situation where the fire hose 10 accidentally opens the electric control valve when it is reeled, thereby avoiding the waste of water resources.

[0019] The clamping assembly 15 includes a clamping seat 29, a second screw 28 and a second motor 27. Two support blocks 32 are provided on the box body 8. The two ends of the second screw 28 are rotatably connected to the two support blocks 32. The water gun head 14 is provided with an annular groove 13. Two clamping seats 29 are provided, and the clamping seat 29 is provided with an arc-shaped notch 30 that matches the annular groove 13. The second screw 28 has threads with opposite rotation directions at both ends, and the second screw 28 is threadedly connected to the two clamping seats 29. The second motor 27 is fixed to the second screw 28. A pressure block 31 is provided on the box body 8 for slidingly guiding the clamping seat 29. When the second motor 27 rotates, the second screw 28 can be driven to rotate synchronously, so that the two clamping seats 29 can slide horizontally along the pressure block 31. When the two clamping seats 29 are close to each other, they can rely on the arc-shaped recess 30 and the annular groove 13 to clamp the water gun head 14. When the two clamping seats 29 are away from each other, the clamping state of the water gun head 14 can be released, thereby facilitating the subsequent pulling out of the fire hose 10 from the box body 8.

[0020] Working principle: When a fire occurs, the control panel 9 is used to make the first motor 17 and the second motor 27 work. The second motor 27 drives the two clamping seats 29 to move away from each other, thereby releasing the clamping state of the two water gun heads 14. The first motor 17 drives one of the first screw rods 24 to rotate, and the other first screw rods 24 rotate by the meshing transmission of the gear 22, so that all the sliders 25 begin to slide toward the middle of the mounting frame 3, and the second guide rings 16 on one side of the slider 25 are arranged in a row according to their height, so that the fire hose 10 can be smoothly pulled out of the box 8. When the second guide ring 16 hits the pressure sensor 20, the electric control valve opens, allowing water to flow out of the fire hose 10 and pass through the water gun head 14. A high-pressure water flow is formed to achieve fire extinguishing. During the whole process, there is no need to manually install or unwind the fire hose 10, thereby shortening the preparation time for fire extinguishing, and two fire hoses 10 can extinguish the fire at the same time, and the fire source is extinguished more quickly. After the fire extinguishing is completed, the first motor 17 is used to drive the first screw 24 to rotate in the opposite direction, so that all the sliders 25 slide toward the two sides of the mounting frame 3, so that the fire hose 10 presents a curved serpentine structure on the side of the mounting frame 3, so that the two fire hoses 10 can be stored in the first mounting cavity 19, and the water in the fire hose 10 can be discharged during this process, and finally the second motor 27 is used to drive the two clamping seats 29 to approach each other, thereby fixing the water gun head 14.
