Description

Technical Field

[0001] The utility model relates to the technical field of fire hydrants, and particularly relates to an underground fire hydrant for fire protection. Background Technique

[0002] A fire hydrant, officially called a fire hose standpipe, is a fixed fire-fighting facility. Its main functions are to control combustibles, isolate combustion-supporting substances, and eliminate ignition sources. It is divided into indoor fire hydrants and outdoor fire hydrants. The fire protection system includes an outdoor fire hydrant system, an indoor fire hydrant system, a fire extinguisher system, and some may also have an automatic sprinkler system, a water cannon system, a gas fire extinguishing system, a fire detection system, a water mist system, etc. The fire hydrant set is generally composed of a fire box, a fire hose, a water gun, a coupling, a plug, a clip, etc. The fire hydrant is mainly used for fire trucks to draw water from the municipal water supply network or the outdoor fire water supply network to implement fire fighting, and can also be directly connected to the water hose and the water gun to discharge water for fire fighting. Therefore, the fire hydrant system is also one of the important fire-fighting facilities for extinguishing fires.

[0003] Chinese patent document CN216075350U discloses an underground fire hydrant for fire protection engineering, including a fire hydrant main body. A protective cover is arranged at the top of the fire hydrant main body. An adjusting wheel is arranged at the top of the protective cover. A rotating rod is fixedly connected to the bottom of the adjusting wheel. The other end of the rotating rod is fixedly connected to a threaded rod. The threaded rod is externally threaded with a lifting valve. Water delivery pipelines are arranged on both sides of the lifting valve. The other ends of the water delivery pipelines are provided with water outlet pipes. A buried chassis is arranged at the bottom of the fire hydrant main body. Fixing holes are arranged through the inside of the buried chassis. There are several fixing holes. By using the fixing holes arranged through the inside of the buried chassis and cooperating with the fixing bolts threadedly connected inside the fixing holes, the fire hydrant can be firmly fixed underground. By using the pressure groove arranged outside the fire hydrant main body, the internal pressure of the fire hydrant during water discharge can be effectively relieved.

[0004] The following problems exist in the prior art:

[0005] 1. For the existing underground fire hydrants for fire protection, when a fire occurs, firefighters need to dig out the fire hydrants buried underground to use them. This not only consumes the physical strength of firefighters, but also may cause irreparable losses in serious disaster situations.

[0006] 2. For the existing underground fire hydrants for fire protection, because the fire hydrants are buried underground for a long time, there will be a lot of soil at the water outlet of the fire hydrant. In case of an emergency, the soil will hinder the connection between the fire hose and the fire hydrant, affecting the rescue of the disaster situation. Summary of the Utility Model

[0007] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0008] A buried fire hydrant for fire fighting, comprising a fixed sleeve, the lower end of the fixed sleeve is fixedly connected with a base, a fire hydrant is arranged inside the fixed sleeve, a water outlet connection assembly is fixedly connected to the front end of the fire hydrant, and a valve is movably connected to the upper end of the fire hydrant.

[0009] Preferably, the valve includes a rotating handle, the lower end of the rotating handle is fixedly connected with a water blocking shaft, and the surface of the water blocking shaft is movably connected with the inside of the fire hydrant.

[0010] Preferably, fixing holes are opened at the four corners of the lower end of the base, and the inside of the fixing holes is fixedly connected with the ground through movable bolts.

[0011] Preferably, a water outlet groove is opened on the front inner wall of the fixed sleeve.

[0012] Preferably, limiting grooves are opened on the left and right inner walls of the fixed sleeve.

[0013] Preferably, fixing blocks are fixedly connected to the upper and lower ends inside the limiting grooves, motors are fixedly connected to the upper ends of the fixing blocks, rotating rods are fixedly connected to the output ends of the motors, moving blocks are movably connected to the surfaces of the rotating rods, and one end of the moving block is fixedly connected with the surface of the fire hydrant.

[0014] Preferably, a positioning plate is fixedly connected to the front end of the fire hydrant, and three buckles are fixedly connected to the front end of the positioning plate.

[0015] Preferably, three positioning sleeves are fixedly connected to the front end of the positioning plate, the positioning sleeves are located inside the buckles, springs are fixedly connected to the inside of the positioning sleeves, movable columns are fixedly connected to the front ends of the springs, and movable plates are fixedly connected to the front ends of the movable columns, and the movable plates are located behind the buckles.

[0016] Due to the adoption of the above technical solutions, the technical progress achieved by the present utility model compared with the prior art is:

[0017] 1. The present utility model provides a buried fire hydrant for fire fighting. Through the combined action of the motor, limiting grooves, fixing blocks, rotating rods and moving blocks, the automatic lifting of the fire hydrant can be realized. When there is no disaster, the fire hydrant will be buried underground. When there is a disaster, the fire hydrant will automatically rise, which is convenient for firefighters to fight the fire. By controlling the rotation of the motor, the rotating rod inside the limiting groove rotates on the fixing block, and then the moving block moves up and down inside the limiting groove, thereby driving the fire hydrant to move up and down inside the fixed sleeve, realizing the automatic lifting of the fire hydrant.

[0018] 2. The utility model provides a buried fire hydrant for fire fighting. Through the combined action of a positioning plate, a buckle, a positioning sleeve, a spring, a movable column and a moving plate, the protection of the water outlet connection assembly can be realized, preventing soil from entering the interior of the water outlet connection assembly, enabling firefighters to immediately use the fire hydrant when they arrive at the fire site, saving a large amount of time for firefighters. By manually aligning the fire hose with the water outlet and then squeezing the fire hose backward, the fire hose squeezes the moving plate, and then the movable column at the rear end of the moving plate squeezes the spring inside the positioning sleeve, separating the buckle on the moving plate and the positioning plate to form a gap, facilitating the movement of the clamping block on the fire hose. Then, manually rotate the fire hose clockwise to connect the buckle on the water outlet connection assembly with the clamping block on the fire hose, fixing the fire hose.

[0031] In this embodiment, by manually aligning the fire hose with the water outlet and then squeezing the fire hose backward, the fire hose squeezes the moving plate 56, and then the movable column 55 at the rear end of the moving plate 56 squeezes the spring 54 inside the positioning sleeve 53, separating the moving plate 56 from the buckle 52 on the positioning plate 51 to form a gap, facilitating the movement of the clamping block on the fire hose. Then manually rotate the fire hose clockwise to connect the buckle 52 on the water outlet connection assembly 5 with the clamping block on the fire hose, fixing the fire hose.

[0032] The working principle of the present utility model is as follows: By controlling the rotation of the motor 11, the rotating rod 15 inside the limit groove 13 rotates on the fixed block 14, and then the moving block 16 moves up and down inside the limit groove 13, thereby driving the fire hydrant 3 to move up and down inside the fixed sleeve 1, realizing the automatic lifting of the fire hydrant 3. Manually align the fire hose with the water outlet, and then squeeze the fire hose backward, so that the fire hose squeezes the moving plate 56, and then the movable column 55 at the rear end of the moving plate 56 squeezes the spring 54 inside the positioning sleeve 53, separating the buckle 52 on the moving plate 56 and the positioning plate 51 to form a gap, facilitating the movement of the block on the fire hose. Then manually rotate the fire hose clockwise so that the buckle 52 on the water outlet connection assembly 5 is connected to the block on the fire hose to fix the fire hose. After connecting the fire hose, manually rotate the rotating handle 41 to move the water blocking shaft 42 upward, allowing water to come out from the water outlet, realizing water spraying on the fire.
