Description

Technical Field

[0001] This utility model belongs to the field of fire hydrant technology, and in particular relates to an anti-collision fire hydrant. Background Technology

[0002] Outdoor fire hydrants are water supply facilities installed on the fire water supply network outside buildings. They are mainly used by fire trucks to draw water from the municipal water supply network or the outdoor fire water supply network to extinguish fires. They can also be directly connected to fire hoses and nozzles to extinguish fires. They are one of the important fire-fighting facilities for fighting fires.

[0003] While outdoor fire hydrants are convenient to use as they can be filled with water from the ground, their visibility is low at night, making them vulnerable to collisions with vehicles. Such collisions can easily damage them. Therefore, it is necessary to provide a crash-resistant fire hydrant to address these issues. Utility Model Content

[0004] To address the technical problems of existing outdoor fire hydrants being susceptible to damage due to low visibility at night and being vulnerable to vehicle collisions, this utility model provides a collision-resistant fire hydrant.

[0005] This utility model is implemented as follows: a fire hydrant with anti-collision features includes: a fire hydrant body, on which an annular mounting seat is rotatably mounted, and the annular mounting seat has an mounting groove; and an arc-shaped plate slidably mounted on the mounting groove via a mounting block, the arc-shaped plate having an anti-collision reflective mechanism for protecting the fire hydrant body.

[0006] Preferably, the anti-collision reflective mechanism includes: a bracket disposed on the arc-shaped plate; and an anti-collision barrel rotatably mounted on the bracket via a rotating shaft, wherein reflective strips are fixedly installed on the outer wall of the anti-collision barrel.

[0007] Preferably, the anti-collision fire hydrant further includes a buffer mechanism installed on the mounting groove to protect the fire hydrant body. The buffer mechanism includes a damping pad fixedly installed on the inner wall of the mounting groove, a spring fixedly installed on the damping pad, and one end of the spring contacting the mounting block.

[0008] Preferably, a support plate is fixedly installed on the annular mounting base, and a limit rod is slidably installed on the support plate, with one end of the limit rod being fixedly connected to the arc-shaped plate.

[0009] Preferably, a threaded rod is fixedly installed at one end of the limiting rod, and a cover is threaded onto the threaded rod, the cover being used to block the support plate.

[0010] Preferably, the bracket is L-shaped and is fixedly mounted on the arc-shaped plate by bolts.

[0011] Preferably, the anti-collision barrel is made of plastic material, and a rotating rod is fixedly installed on the cover.

[0012] Compared with related technologies, the anti-collision fire hydrant provided by this utility model has the following beneficial effects:

[0013] This solution utilizes reflective strips in the anti-collision reflective mechanism to reflect strong light under vehicle headlights, improving nighttime warning effects and enabling occupants to notice the fire hydrant promptly for timely avoidance, thus reducing the risk of collision. The anti-collision barrel in the mechanism absorbs impact force through its own deformation, reducing the impact force transmitted to the curved plate. When the curved plate is impacted, it pushes the mounting block to slide within the mounting groove due to the impact force, absorbing impact energy through displacement. This significantly reduces the damage rate of the fire hydrant itself, providing good protection. If a vehicle simply grazes the fire hydrant, the anti-collision barrel will rotate, and the annular mounting seat will also rotate on the fire hydrant body. This rotation reduces wear between the vehicle and the fire hydrant, lowering maintenance costs and providing good protection. This solution addresses the technical problems of existing outdoor fire hydrants being susceptible to damage from vehicle collisions at night due to low visibility. Attached Figure Description

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the specification and the foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification or the foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] This utility model embodiment provides an anti-collision fire hydrant, such as Figure 1-4 As shown, the anti-collision fire hydrant includes: a fire hydrant body 1, an annular mounting seat 2 rotatably mounted on the fire hydrant body 1, and an mounting groove 3 provided on the annular mounting seat 2; and an arc-shaped plate 5 slidably mounted on the mounting groove 3 via a mounting block 4, and an anti-collision reflective mechanism for protecting the fire hydrant body 1 is installed on the arc-shaped plate 5.

[0022] In this design, the fire hydrant body 1 is based on existing technology and can provide water to fire-fighting facilities when needed. When used at night, the reflective strips 10 in the anti-collision reflective mechanism reflect light to warn vehicles, allowing occupants to notice the fire hydrant in time and avoid it, thus reducing the risk of collision. When a vehicle collides with the fire hydrant, the anti-collision barrel 9 in the anti-collision reflective mechanism will first contact the vehicle and absorb the impact force through its own deformation. Then, the remaining impact force will be transferred to the arc plate 5, causing the arc plate 5 to push the mounting block 4 to slide in the mounting groove 3 due to the impact force. By absorbing the impact energy through displacement, the damage rate of the fire hydrant body 1 can be greatly reduced, and the protection effect is good. If the vehicle simply brushes past the fire hydrant, the annular mounting seat 2 will rotate on the fire hydrant body 1. This rotation can reduce the wear between the vehicle and the fire hydrant, reduce maintenance costs, and provide good protection.

[0023] In a further preferred embodiment of the present invention, the anti-collision reflective mechanism includes: a bracket 7 disposed on the arc plate 5; an anti-collision barrel 9 rotatably mounted on the bracket 7 via a rotating shaft 8, wherein a reflective strip 10 is fixedly installed on the outer wall of the anti-collision barrel 9.

[0024] In this embodiment, the anti-collision reflective mechanism is used to protect the fire hydrant body 1. When in use, the reflective strips 10 on the outer wall of the anti-collision barrel 9 reflect strong light under the illumination of the vehicle headlights, improving the nighttime warning effect and enabling people in the vehicle to notice the fire hydrant in time so as to avoid it in time, thereby reducing the risk of collision. When the vehicle collides with the anti-collision barrel 9, the anti-collision barrel 9 rotates on the bracket 7 through the pivot 8, converting the impact force into rotational kinetic energy, reducing the direct impact on the arc plate 5. After the collision, the anti-collision barrel 9 can absorb the impact force by its own deformation, which can reduce the impact force transmitted to the arc plate 5 and greatly reduce the damage caused by the impact force to the fire hydrant body 1.

[0025] In a further preferred embodiment of the present invention, the anti-collision fire hydrant further includes a buffer mechanism installed on the mounting groove 3 for protecting the fire hydrant body 1. The buffer mechanism includes a damping pad 11 fixedly installed on the inner wall of the mounting groove 3, and a spring 12 fixedly installed on the damping pad 11. One end of the spring 12 is in contact with the mounting block 4.

[0026] In this embodiment, when the arc plate 5 is impacted, the arc plate 5 will cause the mounting block 4 to slide along the mounting groove 3 due to displacement and compress the spring 12. The spring 12 absorbs the impact energy through elastic deformation. At the same time, the damping pad 11 also absorbs the impact energy on the spring 12, forming a double buffering effect. After the impact ends, the restoring force of the spring 12 pushes the mounting block 4 to reset, so that the arc plate 5 returns to the initial protective position, thereby ensuring that the fire hydrant body 1 obtains continuous and stable anti-collision protection.

[0027] In a further preferred embodiment of the present invention, a support plate 13 is fixedly installed on the annular mounting base 2, and a limiting rod 14 is slidably installed on the support plate 13, with one end of the limiting rod 14 fixedly connected to the arc-shaped plate 5.

[0028] In this embodiment, the combined use of the limiting rod 14 and the support plate 13 can improve the stability of the arc plate 5 during use, making the arc plate 5 more stable during movement.

[0029] In a further preferred embodiment of the present invention, a threaded rod 15 is fixedly installed at one end of the limiting rod 14, and a cover 16 is threadedly installed on the threaded rod 15. The cover 16 is used to block the support plate 13.

[0030] In this embodiment, the use of the cover 16 can prevent the limiting rod 14 from detaching from the support plate 13. When the arc plate 5 is severely damaged due to impact, the cover 16 is first removed from the threaded rod 15. After removal, the arc plate 5 can be pulled outward, so that the limiting rod 14 can detach from the support plate 13, and the mounting block 4 can detach from the mounting groove 3 and the spring 12. In this way, it is convenient for personnel to replace the severely damaged arc plate 5.

[0031] In a further preferred embodiment of the present invention, the bracket 7 is configured as an L-shape, and the bracket 7 is fixedly installed on the arc-shaped plate 5 by bolts 6.

[0032] In this embodiment, the use of bolts 6 allows the crash barrier 9 to be replaced when it is severely damaged. When replacing it, bolts 6 are removed first, so that bracket 7 can be removed from the arc plate 5. After removal, the damaged crash barrier 9 can be removed. By reversing the operation, a new crash barrier 9 can be replaced.

[0033] In a further preferred embodiment of this utility model, the anti-collision barrel 9 is made of plastic material, and a rotating rod is fixedly installed on the cover 16.

[0034] In this embodiment, the anti-collision barrel 9 made of plastic material can achieve lightweight buffering. When it is impacted, it can absorb impact energy through plastic deformation, and the buffering effect is good. The use of the rotating rod makes it convenient for people to rotate the cover 16 by hand.

[0035] In summary, compared with related technologies, this solution, through the reflective strip 10 in the anti-collision reflective mechanism, can reflect strong light under vehicle headlight illumination, improving the nighttime warning effect and enabling occupants of vehicles to notice the fire hydrant in time for timely avoidance, thus reducing the risk of collision. The anti-collision barrel 9 in the anti-collision reflective mechanism can absorb impact force through its own deformation, reducing the impact force transmitted to the arc-shaped plate 5. When the arc-shaped plate 5 is impacted, it will push the mounting block 4 to slide within the mounting groove 3 due to the impact force, absorbing impact energy through displacement. This significantly reduces the damage rate of the fire hydrant body 1, providing good protection. If the vehicle simply brushes past the fire hydrant, the anti-collision barrel 9 will rotate, and the annular mounting seat 2 will also rotate on the fire hydrant body 1. This rotation reduces wear between the vehicle and the fire hydrant, lowering maintenance costs and providing good protection. This solution solves the technical problems of existing outdoor fire hydrants being susceptible to damage from vehicle collisions at night due to low visibility.
