[0002] A fire hydrant is a fixed fire-fighting facility. It is installed on a water pipe and is closed under normal circumstances. In the event of a fire, the fire hydrant can be quickly opened through the switch on the fire hydrant and connected to the fire pipe. A large amount of water can be output through the fire hydrant to extinguish the fire. Fire hydrants are usually cast with metal materials, which are high in strength and resistant to high temperatures. They will not be damaged even in a serious fire or when hit by heavy objects. They are very durable and reliable, and are easy to use, which can effectively reduce the losses caused by a fire.

[0003] Although the above-mentioned existing technology can solve the corresponding technical problems, it still has certain defects: most of the existing fire hydrants are used outdoors. Since the fire hydrants can be opened by twisting, when they are used outdoors in areas with less strict supervision, they are easily unscrewed and connected to pipes to steal water, which not only easily leads to the theft and waste of water resources, but also in the event of a fire, the fire hydrants need to be closed again and the water theft pipelines need to be disconnected and reconnected to the fire water pipes, which greatly increases the time consumption and affects the fire extinguishing efficiency.

[0020] See also Figure 1-4 As shown, the technical solution adopted in this specific embodiment is: an intelligent anti-theft water fire hydrant, including a water flow body 1, an opening and closing member is arranged in the water flow body 1, an opening top cover 4 is arranged on the water flow body 1, the bottom end of which extends into the water flow body 1 and is fixedly connected to the opening and closing member, a drainage pipe 2 is arranged on the side wall of the water flow body 1 and is connected to the water flow body 1, the opening top cover 4 includes a connecting plate 48 arranged on the water flow body 1 and an opening and closing rod 41 that penetrates the connecting plate 48 and extends into the water flow body 1 and is fixedly connected to the opening and closing member, and the inner wall of the connecting plate 48 is sleeved on the outer wall of the opening and closing rod 41 The magnetic anti-theft device 45 includes a fixing ring 451 fixedly arranged on the connecting plate 48 and a card slot 452 arranged on the inner wall of the fixing ring 451. The magnetic anti-theft device 45 also includes a snap-fit ​​block 100 sleeved on the outer wall of the opening and closing rod 41 and capable of contacting and engaging with the card slot 452. The snap-fit ​​block 100 includes a ring 453 sleeved on the outer wall of the opening and closing rod 41 and a card block 454 arranged on the outer wall of the ring 453 and capable of contacting and engaging with the card slot 452. The ring 453 is also provided with a plurality of driven magnetic blocks 455, and six are provided in this embodiment. The outer wall of the opening and closing rod 41 can also be detachably provided with a card block 454. There is a magnetic block 46. When in use, the magnetic block 46 is installed to unlock the magnetic anti-theft device 45, and after use, the magnetic block 46 is removed to limit the rotation of the magnetic anti-theft device 45. When in use, when it is necessary to start the fire hydrant, the fire water pipe is connected to the drain pipe 2, and the magnetic block 46 is installed on the upper end of the outer wall of the opening and closing rod 41, so that it generates suction to adsorb the driven magnetic block 455 on the ring 453 of the locking block 100, so that the ring 453 moves upward, and then the block 454 is in contact with the slot 452. At this time, the opening and closing rod 41 can be twisted to drive the opening and closing rod 41 to drive the opening and closing rod 41 to open the water body 1. The closure piece opens and closes the fire hydrant. When the fire hydrant needs to be locked after use, the magnetic block 46 is removed from the opening and closing rod 41 and taken away. At this time, the suction force generated by the magnetic block 46 on the driven magnetic block 455 disappears, so that the ring 453 falls along the opening and closing rod 41 by gravity, and the clamping block 454 is re-inserted into the clamping groove 452. When the opening and closing rod 41 is rotated, the clamping block 454 is stuck in the clamping groove 452, which effectively avoids the occurrence of water theft. The opening and closing only requires the installation or removal of the magnetic block 46, which is very quick and convenient, reducing the time consumption of opening and closing when a fire occurs, and ensuring the efficiency of fire extinguishing.

[0021] The bottom of the water-passing body 1 is also provided with a connecting flange 5, which is conducive to making the connection between the fire hydrant and the water pipe more convenient;

[0022] The upper surface of the connecting plate 48 is also provided with a sealing cover 44, and the bottom surface of the magnetic block 46 is in contact with the outer wall of the sealing cover 44, which is conducive to shielding the rotating part of the opening and closing rod 41, preventing dust from entering and affecting the rotation of the opening and closing rod 41, and making the installation of the magnetic block 46 more convenient;

[0023] The top of the opening and closing rod 41 is also provided with a twisting handle 42, which is conducive to making the twisting of the opening and closing rod 41 more labor-saving;

[0024] The twist handle 42 is detachably arranged on the top of the opening and closing rod 41. The top surface of the opening and closing rod 41 is provided with a hexagonal groove. A hexagonal fixing bolt 43 whose bottom is buckled with the hexagonal groove is inserted through the center of the twist handle 42, which is conducive to making the twist handle 42 detachable. Then, the twist handle 42 can be removed and taken away after use, making the anti-theft performance stronger. At the same time, the hexagonal fixing bolt 43 cooperates with the hexagonal groove, and the disassembly and assembly are simple;

[0025] The outer wall of the opening and closing rod 41 is provided with a sliding groove 47, and the inner wall of the ring 453 is provided with a slider 456 slidably connected to the inner wall of the sliding groove 47, which is conducive to allowing the ring 453 to slide up and down while preventing it from lateral twisting, thereby ensuring the locking effect of the opening and closing rod 41.

[0026] Working principle of the utility model: When the utility model is used, when it is necessary to start the fire hydrant, the fire water pipe is connected to the drain pipe 2, and the magnetic suction block 46 is installed on the upper end of the outer wall of the opening and closing rod 41, so that it generates suction to adsorb the driven magnetic block 455 on the ring 453 of the locking block 100, so that it drives the ring 453 to move upward, and then the clamping block 454 is in contact with the clamping groove 452. At this time, the opening and closing rod 41 can be twisted, and the opening and closing part in the water flow body 1 is driven by the opening and closing rod 41 to open and close the fire hydrant. After use, it needs to be locked. When using a fire hydrant, the magnetic block 46 is removed from the opening and closing rod 41 and taken away. At this time, the suction force generated by the magnetic block 46 on the driven magnetic block 455 disappears, so that the ring 453 falls along the opening and closing rod 41 through gravity, and the clamping block 454 is re-inserted into the clamping groove 452. When the opening and closing rod 41 is rotated, the clamping block 454 is stuck in the clamping groove 452 and cannot be rotated, thereby effectively avoiding the occurrence of water theft. Moreover, opening and closing only requires the installation or removal of the magnetic block 46, which is very quick and convenient, reducing the time consumption of opening and closing when a fire occurs, and ensuring the efficiency of fire extinguishing.
