Description

Technical Field

[0001] The utility model relates to the technical field of fire hydrants, in particular to a telescopic fire hydrant device. Background Art

[0002] Fire hydrants, formally called fire hydrants, are a type of fixed fire-fighting facilities. Their main function is to control combustibles, isolate combustible materials, and eliminate sources of ignition. They are divided into indoor fire hydrants and outdoor fire hydrants. Fire hydrants are mainly used for fire trucks to take water from the municipal water supply network or the outdoor fire water supply network to implement fire extinguishing. They can also be directly connected to water hoses or water guns to discharge water for fire extinguishing. Therefore, indoor and outdoor fire hydrant systems are also one of the important fire-fighting facilities for fighting fires.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-4The utility model discloses a telescopic fire hydrant device, including a ground layer 1, characterized in that: a placement groove 2 is opened on the ground layer 1, a fixing pipe 3 is installed on the bottom inner wall of the placement groove 2, the inner cavity of the fixing pipe 3 is liftably connected with a lifting screw 4 driven by a worm gear mechanism, the top of the lifting screw 4 is fixedly connected to a lifting plate 5, a bolt body 6 is installed on the lifting plate 5, and a protrusion 16 is fixedly connected to the top of the bolt body 6, a cover body 8 that can cover the placement groove 2 is provided on the ground layer 1, and a groove 15 matching the protrusion 16 is opened at the bottom of the cover body 8.

[0019] A controller electrically connected to the worm gear mechanism may be provided on the lifting plate 5 , and the controller signal is connected to the corresponding remote control switch device so as to control the worm gear mechanism to lift the bolt body 6 when the cover body 8 is not opened.

[0020] Specifically, a guide rod 9 is installed at the bottom of the placement groove 2, and the lifting plate 5 is movably sleeved on the guide rod 9.

[0021] A linear bearing 18 that cooperates with the guide rod 9 is installed on the lifting plate 5 .

[0022] In this embodiment, the provision of the guide rod 9 can guide the lifting and lowering of the lifting plate 5 , and the provision of the linear bearing 18 can make the lifting plate 5 move more smoothly along the guide rod 9 .

[0023] Specifically, the worm gear mechanism includes a fixed box 10, a limit bearing 11, a worm wheel 12, a worm 13 and a motor 14. The top of the fixed tube 3 is fixedly connected to the fixed box 10. The fixed box 10 is equipped with two upper and lower limit bearings 11.
