Description

Technical Field

[0001] The utility model relates to the technical field of outdoor fire hydrant protection, in particular to an anti-collision fire hydrant. Background Art

[0002] A fire hydrant is a device installed in or around a building to provide water for firefighting. It is usually composed of pipes, valves, joints, etc. Fire hydrants are an important part of firefighting facilities. They are used to supply water for firefighting and help firefighters to extinguish fires. Therefore, fire hydrants are widely distributed in cities, and some fire hydrants on the roadside are easily hit by passing vehicles.

[0003] For this purpose, the utility model patent with announcement number CN221072846U discloses an anti-collision fire hydrant, which relates to the field of outdoor fire hydrant protection, including ground and underground pipelines, the upper flange of the underground pipeline is connected with a hose, and the underground pipeline and the hose are installed below the ground, a fire hydrant is installed above the ground, and the lower flange of the fire hydrant is connected to the upper end of the hose, and a rubber protective layer is arranged on the outside of the fire hydrant, and multiple groups of metal rods are arranged around the fire hydrant on the ground, and multiple groups of anti-collision buckets are arranged on the outside of the metal rods on the ground. The utility model is provided with a high-strength hose installed at one end between the fire hydrant and the underground pipeline. When the fire hydrant on the ground is impacted, the impact of the fire hydrant on the underground pipeline is reduced due to the good toughness of the hose. At the same time, the anti-impact high-strength metal rods, anti-collision buckets and spring steel are arranged around the fire hydrant to reduce the damage caused by external impact to the fire hydrant.

[0004] However, this patent reduces the damage caused by external impact to the fire hydrant by providing multiple sets of metal rods. However, when the fire hydrant is needed, the multiple sets of metal rods will affect the connection between the water pipe and the fire hydrant, affecting the water discharge effect of the fire hydrant. Utility Model Content

[0005] The utility model aims to provide an anti-collision fire hydrant to address the deficiencies of the prior art, which can avoid affecting the water discharge effect of the fire hydrant when in use.

[0006] The technical solution adopted by the utility model is an anti-collision fire hydrant, including a base plate and a fire hydrant body. The fire hydrant body is radially provided with a water outlet, a through hole is provided in the middle of the base plate, the base plate is sleeved on the surface of the fire hydrant body through the through hole, and fixed columns integrally formed with the base plate are provided at the four corners of the base plate. The fixed column is a hollow structure, a movable column is provided inside the fixed column, and a lifting device is provided inside the fixed column and the movable column. The movable column is slidably connected to the fixed column through the lifting device, and an anti-collision device is provided on one side of the movable column.

[0007] Preferably, the lifting device includes a threaded hole, which is opened in the movable column. A threaded column is rotatably installed in the threaded hole. The bottom of the threaded column is rotatably connected to the inner wall of the bottom of the fixed column. A worm gear is fixedly installed on the outer wall of one end of the threaded column close to the bottom of the fixed column. A worm is rotatably connected to one side of the worm gear. One end of the worm passes through the fixed column and is fixedly connected to a transmission column. The transmission column passes through the fixed column on the same side of the base plate and is fixedly connected to a handle.

[0008] Preferably, the anti-collision device includes a baffle and a storage groove. The two ends of the baffle are respectively fixedly connected to the movable columns on both sides of the base plate. A reinforcement rod is fixedly installed in the base plate, and multiple springs are fixedly installed around the reinforcement rod. The storage groove is opened in the fixed column below the baffle.

[0009] Preferably, the fixed column and the movable column have rounded corners at their sharp points.

[0010] Preferably, mounting blocks integrally formed with the bottom plate are provided at the four corners of the bottom plate, and mounting holes are provided in the mounting blocks.

[0011] Preferably, a reinforcement block is provided on one side of the bottom of the fixing column, one end of the reinforcement block is fixedly connected to the fixing column, and the other end of the reinforcement block is fixedly connected to the bottom plate.

[0012] Preferably, reflective plates are provided on the surfaces of the baffles.

[0013] The utility model is simple and convenient to use. It only requires the bottom plate to be sleeved on the surface of the fire hydrant through the through hole, and then the handle is held and rotated to raise the baffle, thereby reducing the impact damage to the fire hydrant. A reinforcing rod and a spring are arranged in the baffle, and the reinforcing rod can effectively improve the strength of the baffle and improve the impact resistance of the baffle. The spring can absorb and provide buffering when the baffle is deformed by impact, thereby further improving the impact resistance of the device. When the fire hydrant is used, it is only necessary to hold the reverse handle and rotate it to lower the height of the baffle, thereby making it convenient for the user to connect the water pipe to the water outlet of the fire hydrant.

[0014] Compared with the prior art, the utility model has the beneficial effects of being easy to install and effectively reducing the impact damage to the fire hydrant, and the baffle height is adjustable to avoid the baffle affecting the connection between the fire hydrant and the water pipe when the fire hydrant needs to be used.

[0021] Figure 1 The utility model schematically shows an anti-collision fire hydrant, including a bottom plate 1, a fire hydrant body 13, a water outlet 14 is radially opened on the fire hydrant body 13, a through hole 12 is opened in the middle of the bottom plate 1, the bottom plate 1 is sleeved on the surface of the fire hydrant body 13 through the through hole 12, and fixed columns 15 integrally formed with the bottom plate 1 are provided at the four corners of the bottom plate 1, the fixed column 15 is a hollow structure, a movable column 16 is provided in the fixed column 15, a lifting device 2 is provided in the fixed column 15 and the movable column 16, the movable column 16 is slidably connected to the fixed column 15 through the lifting device 2, an anti-collision device 3 is provided on one side of the movable column 16, and the fixed column 15 and the movable column 16 are provided with rounded corners 4 at their sharp points, which can effectively reduce the damage caused by bumps and can also effectively avoid scratching the user. The four corners of the bottom plate 1 are provided with mounting blocks 5 integrally formed with the bottom plate 1, and mounting holes 51 are provided in the mounting blocks 5. The device can be fixedly installed by setting fixing tools such as bolts in the mounting holes 51. A reinforcement block 6 is provided on one side of the bottom of the fixed column 15, one end of the reinforcement block 6 is fixedly connected to the fixed column 15, and the other end is fixedly connected to the bottom plate 1. The reinforcement block 6 can form a triangle between the fixed column 15 and the bottom plate 1, thereby improving the strength of the fixed column 15.

[0022] like Figure 2 , Figure 3 and Figure 4The lifting device 2 shown includes a threaded hole 21, which is opened in the movable column 16. A threaded column 22 is rotatably installed in the threaded hole 21. The bottom of the threaded column 22 is rotatably connected to the inner wall of the bottom of the fixed column 15. A worm gear 23 is fixedly installed on the outer wall of one end of the threaded column 22 close to the bottom of the fixed column 15. A worm 24 is rotatably connected to one side of the worm gear 23. One end of the worm 24 passes through the fixed column 15 and is fixedly connected to a transmission column 25.
