Description

Technical Field

[0001] This application relates to the field of fire protection facilities technology, and in particular to an anti-collision structure for a fire hydrant. Background Technology

[0002] A fire hydrant is a fixed fire-fighting water supply facility, typically consisting of valves, outlets, and connecting pipes. It is often installed in urban streets, public buildings, industrial sites, and residential areas. Its core function is to provide a stable high-pressure water source for fire fighting and rescue by connecting with fire hoses, nozzles, and other equipment.

[0003] As a core facility of the urban fire protection system, the anti-collision design of fire hydrants is crucial. Since fire hydrants are mostly located on both sides of the road or in public places, accidental collisions with vehicles are frequent. This not only leads to damage to fire hydrants and leakage of high-pressure water (a single accident may waste more than 200 tons of water resources), but also causes a chain of problems such as traffic congestion and water supply interruption, directly threatening the efficiency of emergency response.

[0004] Currently, most common fire hydrant anti-collision devices (such as cement blocks and metal guardrails) adopt rigid fixing methods. Due to the lack of effective buffer energy absorption design, they are difficult to fully absorb and disperse the impact force when hit by vehicles, which often still causes the main body of the fire hydrant to break or the internal sealing components to be displaced and damaged. Utility Model Content

[0005] To address the problem that insufficient cushioning performance of the aforementioned anti-collision devices can easily lead to damage to fire hydrants, this application provides an anti-collision structure for fire hydrants.

[0006] The anti-collision structure for a fire hydrant provided in this application adopts the following technical solution:

[0007] An anti-collision structure for a fire hydrant includes a fire hydrant body, a protective frame surrounding the fire hydrant body, anti-collision plates on both sides of the protective frame, a force-bearing block fixedly connected to the side of the anti-collision plate near the protective frame, lugs fixedly connected to both sides of the force-bearing block, a first movable rod rotatably connected inside the lugs, a second movable rod rotatably connected to one end of the first movable rod via a pin, a base plate rotatably connected to one end of the second movable rod, a side of the base plate fixedly connected to the protective frame, a transmission rod rotatably connected to one side of the first and second movable rods via a pin, a connecting block fixedly connected to one side of the transmission rod, a spring fixedly connected to one side of the connecting block, and one end of the spring fixedly connected to the base plate.

[0008] Preferably, the surface of the anti-collision plate has multiple circular holes, and a guide post is slidably connected inside the circular holes. A stop block is fixedly connected to one end of the guide post, and a damper is fixedly connected to the other end of the guide post. One end of the damper is fixedly connected to the protective frame.

[0009] Preferably, the protective frame has an outer door hinged to its front, and a lock is provided at the connection between the outer door and the protective frame. Multiple mounting blocks are fixedly connected to the bottom of the protective frame, and a ground cone is provided in the middle of each mounting block.

[0010] Preferably, the base plate is U-shaped, with its opening facing away from the protective frame.

[0011] Preferably, the first movable rod and the second movable rod have the same specifications, and the connecting block is made of a soft energy-absorbing material.

[0012] Preferably, the side of the anti-collision plate away from the protective frame is provided with a buffer pad layer, and the outer surface of the anti-collision plate is provided with a reflective warning strip.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. When impacted by external forces such as vehicles, the anti-collision plate first absorbs the impact force, and then drives the first and second movable rods to rotate through the force-bearing block and the lug. With the help of the transmission rod, it pushes the connecting block and the spring. The elastic deformation of the spring and the deformation of the soft energy-absorbing material connecting block are used to absorb energy. At the same time, the cooperation between the guide column and the damper further consumes the impact force, preventing the main body of the fire hydrant from being damaged due to direct force.

[0015] 2. The protective frame's outer door and lock prevent human-caused damage, while the ground cone and mounting block enhance the overall installation's stability and prevent structural displacement during impact. The buffer pad and reflective warning strip on the outside of the crash plate further buffer the initial impact force and alert passing vehicles in low-visibility conditions, actively reducing the probability of a collision.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0022] Reference Figure 1-4 This utility model provides an anti-collision structure for a fire hydrant, including a fire hydrant body 1, a protective frame 101 around the fire hydrant body 1, anti-collision plates 2 on both sides of the protective frame 101, a force-bearing block 3 fixedly connected to the side of the anti-collision plate 2 near the protective frame 101, and lugs 301 fixedly connected to both sides of the force-bearing block 3. A first movable rod 302 is rotatably connected inside the lugs 301. A second movable rod 303 is rotatably connected to one end of the first movable rod 302 via a pin. A base plate 304 is rotatably connected to one end of the second movable rod 303. One side of the base plate 304 is fixedly connected to the protective frame 101. A transmission rod 305 is rotatably connected to one side of the first movable rod 302 and the second movable rod 303 via a pin. A connecting block 306 is fixedly connected to one side of the transmission rod 305. A spring 307 is fixedly connected to one side of the connecting block 306. One end of the spring 307 is fixedly connected to the base plate 304.

[0023] When an external force (such as a vehicle impact) acts on the crash barrier 2, the impact force first acts on the crash barrier 2, which then transmits the force to the load-bearing block 3. After the load-bearing block 3 is subjected to force, the lugs 301 on both sides drive the first movable rod 302 to rotate. The first movable rod 302, through a pin, drives the second movable rod 303 to rotate. Since the second movable rod 303 is rotatably connected to the U-shaped base plate 304, which is fixed to the protective frame 101, it provides stable support. During the rotation of the first and second movable rods 302 and 303, the transmission rod 305 moves through the pin, which in turn pushes the connecting block 306. The connecting block 306 compresses the spring 307, causing the spring 307 to deform and absorb part of the impact force. Simultaneously, the connecting block 306, made of a soft energy-absorbing material, also deforms under stress to further absorb energy.

[0024] Through the coordinated action of components such as the force-bearing block 3, the first movable rod 302, the second movable rod 303, the transmission rod 305, the connecting block 306, and the spring 307, the impact force can be effectively absorbed and dispersed, reducing the risk of damage to the fire hydrant body 1 and better protecting the fire hydrant body 1.

[0025] In a preferred embodiment, the surface of the anti-collision plate 2 is provided with a plurality of circular holes 201, and a guide post 202 is slidably connected inside the circular holes 201. A stop block 203 is fixedly connected to one end of the guide post 202, and a damper 204 is fixedly connected to the other end of the guide post 202. One end of the damper 204 is fixedly connected to the protective frame 101.

[0026] When the crash barrier 2 is impacted, it moves towards the protective frame 101, at which point the guide post 202 slides within the circular hole 201. The stop block 203 prevents the guide post 202 from dislodging from the circular hole 201. As the crash barrier 2 moves, the guide post 202 pushes the damper 204, generating damping force within the damper 204, which hinders the movement of the guide post 202, thereby absorbing some of the impact force.

[0027] The guide column 202 and the damper 204 work together to enhance the energy absorption effect, which is more effective than the traditional rigid protection structure. The damper 204 can reduce the instantaneous impact force, thereby better protecting the fire hydrant body 1.

[0028] In a preferred embodiment, an outer door 102 is hinged to the front of the protective frame 101, and a lock 103 is provided at the connection between the outer door 102 and the protective frame 101. A plurality of mounting blocks 104 are fixedly connected to the bottom of the protective frame 101, and a ground cone 105 is provided in the middle of the mounting block 104.

[0029] The protective frame 101 provides external protection for the fire hydrant body 1. The outer door 102 is connected to the protective frame 101 by a hinge. When the outer door 102 is closed and locked by the lock 103, it can prevent unauthorized personnel from touching the fire hydrant body 1. The ground cone 105 on the mounting block 104 at the bottom of the protective frame 101 is inserted into the ground, firmly fixing the protective frame 101 to the ground and enhancing the stability of the overall structure.

[0030] In a preferred embodiment, the base plate 304 is U-shaped, with its opening facing away from the protective frame 101.

[0031] The U-shaped base plate 304 is designed to make good use of space, providing more room to accommodate the movement of the spring 307 and the transmission rod 305.

[0032] In a preferred embodiment, the first movable rod 302 and the second movable rod 303 are of the same specifications, and the connecting block 306 is made of a soft energy-absorbing material.

[0033] The first movable rod 302 and the second movable rod 303 are of the same specifications to ensure uniform force distribution and avoid uneven force distribution due to different rod lengths. The connecting block 306 is made of soft energy-absorbing material (such as rubber or polyurethane) to further absorb residual impact force during impact.

[0034] In a preferred embodiment, the side of the crash barrier 2 away from the protective frame 101 is provided with a buffer pad layer, and the outer surface of the crash barrier 2 is provided with a reflective warning strip.

[0035] The buffer pad layer (such as rubber or foam) on the outer side of the crash barrier 2 contacts the vehicle first upon impact, initially absorbing the impact force. Reflective warning strips improve the visibility of fire hydrants at night or in low visibility conditions.

[0036] The foregoing description of an exemplary embodiment of a fire hydrant anti-collision structure provided by this disclosure refers to preferred embodiments. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
