[0002] Ground fire hydrants are essential fire-fighting equipment in southern my country and are widely used in residential areas, office areas, factories, warehouses and other places. In the event of a fire, fire hydrants can provide water to fire trucks in a timely manner. Since they are related to fire safety, ground fire hydrants must ensure safe and stable operation.

[0003] At present, when using ground fire hydrants, they need to be connected to fire water pipes. However, when connecting existing ground fire hydrants to fire water pipes, they are generally connected by threaded connections or flange connections, and they cannot be quickly connected. As a result, firefighters need to spend a lot of time to connect the fire water pipes to the fire hydrants, which affects the fire extinguishing efficiency. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figures 1 to 5 A smart ground fire hydrant includes a fire hydrant body 1, a valve 2 is installed on the surface of the fire hydrant body 1, and two water supply pipes 3 are symmetrically fixedly connected on the surface of the fire hydrant body 1. The surfaces of the two water supply pipes 3 are movably provided with fire water pipes 4. The fire water pipes 4 are water pipes used by firefighters to extinguish fires. When the fire water pipes 4 are connected to the water supply pipes 3, water can be passed into the fire water pipes 4 by opening the valve 2.

[0024] An intelligent connection component is provided between the fire water pipe 4 and the water supply pipe 3; the intelligent connection component includes a first fixing ring 5 and a second fixing ring 6 respectively fixedly installed on the outer walls of the water supply pipe 3 and the fire water pipe 4, and each first fixing ring 5 is fixedly installed with a sealing ring 18 on the side close to the corresponding second fixing ring 6, which can increase the sealing between the contact surfaces of the first fixing ring 5 and the second fixing ring 6, thereby effectively preventing water leakage when the water supply pipe 3 is connected to the corresponding fire water pipe 4. The material of each sealing ring 18 is amino rubber, which has good oil resistance, wear resistance and aging resistance.

[0025] Two electric push rods 7 are fixedly installed on the side of the first fixed ring 5 away from the second fixed ring 6, and the driving ends of the two electric push rods 7 are jointly fixedly installed with a moving ring 8, and the moving ring 8 is movably sleeved on the outer surface of the water supply pipe 3, and two fixing frames 9 are symmetrically fixedly installed on the side of the moving ring 8 away from the fire hydrant body 1. The other ends of the two fixing frames 9 are installed with a positioning frame 10 through a limiting assembly. The limiting assembly includes a groove 15 opened on the side of the fixing frame 9 away from the corresponding moving ring 8, a rotating shaft is rotatably installed in the groove 15, and the rotating shaft is fixedly passed through the end of the positioning frame 10, the upper and lower sides of the positioning frame 10 and the surface of the groove 15 are commonly connected with a coil spring 16, the end of the groove 15 is fixedly installed with a limiting frame 17 abutting against the side wall of the positioning frame 10, and the limiting frame 17 is placed on the side of the rotating shaft away from the corresponding water supply pipe 3, refer to Figure 3-5The limit frame 17 can prevent the positioning frame 10 from rotating in the longitudinal direction away from the first fixing ring 5, and it can first rotate in the direction close to the first fixing ring 5, that is, when the fire water pipe 4 is installed and put on the corresponding water supply pipe 3, it can push the positioning frame 10 to rotate inward, which facilitates the connection and fixation of the fire water pipe 4 and the water supply pipe 3, thereby improving the connection speed of the fire water pipe 4 and the fire hydrant body 1.

[0026] A first push-type switch 11 is installed on the side of the first fixing ring 5 close to the second fixing ring 6, and the first push-type switch 11 is electrically connected to the two electric push rods 7; a second push-type switch 12 is installed on the top of the fire hydrant body 1, and the second push-type switch 12 is electrically connected to each electric push rod 7. The circuit connection structure between the first push-type switch 11 and the second push-type switch 12 and the corresponding electric push rod 7 is similar to the double-control switch in the household light control switch, that is, when the first push-type switch 11 is touched, the driving ends of the corresponding two electric push rods 7 will be extended, and when the second push-type switch 12 is touched, the driving end of each electric push rod 7 will be shortened. As for its circuit structure, this technical solution will not be described in detail. It is a commonly used technical means for technical personnel in this field and is also an existing public technology.

[0027] Furthermore, a positioning block 13 is fixedly installed on one side of each first fixing ring 5 close to the corresponding second fixing ring 6, and a positioning hole 14 matching the positioning block 13 is opened on the surface of each second fixing ring 6. When the fire water pipe 4 is sleeved on the corresponding water supply pipe 3, the clamping connection between the positioning block 13 and the positioning hole 14 can prevent the fire water pipe 4 from rotating, thereby ensuring the connection stability between the water supply pipe 3 and the fire water pipe 4.

[0028] The working principle of this utility model is:

[0029] When water is needed to extinguish a fire and the fire hose 4 and the water supply pipe 3 are connected, the fire hose 4 is first placed along the corresponding water supply pipe 3 and sleeved on its surface. At this time, the second fixing ring 6 pushes the corresponding positioning frame 10 to rotate inward and causes the coil spring 16 to generate a deformation force. When the second fixing ring 6 is separated from the positioning frame 10, the positioning frame 10 will reverse and reset under the action of the coil spring 16 until it contacts the limit frame 17. At this time, the positioning frame 10 will be in a vertical state with the fixing frame 9 and cannot rotate in the opposite direction away from the second fixing ring 6.

[0030] When the second fixing ring 6 continues to move toward the direction of the first fixing ring 5 and touches the first push-type switch 11, the driving ends of the corresponding two electric push rods 7 are synchronously extended, pushing the moving ring 8 to move away from the first fixing ring 5 until the positioning frame 10 contacts the second fixing ring 6 and presses it tightly against the surface of the first fixing ring 5, thereby realizing automatic and rapid connection between the fire water pipe 4 and the water supply pipe 3, reducing the connection time of the fire water pipe 4 and the fire hydrant body 1, improving the connection efficiency, and having a certain intelligent effect;

[0031] Finally, after the fire is extinguished, when the fire water pipe 4 needs to be disassembled, press the second push switch 12. At this time, each electric push rod 7 pulls the corresponding movable ring 8 away from the fire hydrant body 1, so that the positioning frame 10 no longer presses against the second fixed ring 6. At this time, pull out the fire water pipe 4 and then lift it upward to remove the fire water pipe 4.

[0032] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are common means well known to those skilled in the art.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
