Description

Technical Field

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

[0002] Fire hydrants, formally known as fire suppression hydrants, are fixed fire protection facilities whose main function is to control combustibles, isolate oxidizers, and eliminate ignition sources. They are divided into indoor and outdoor fire hydrants. Fire protection systems include outdoor fire hydrant systems, indoor fire hydrant systems, fire extinguisher systems, and some may also include automatic sprinkler systems, water cannon systems, gas extinguishing systems, fire detection systems, water mist systems, etc.

[0003] Existing fire hydrants are all made from fire hydrant castings. However, because these safety-grade fire hydrant castings lack any protective measures during installation, they can be damaged if a vehicle hits them, leading to water waste and inconvenience when repairs are needed.

[0004] This utility model was developed to solve this problem. Utility Model Content

[0005] Therefore, in view of the above problems, this utility model proposes a new type of outdoor anti-collision fire hydrant casting with simple structure and anti-collision function.

[0006] To solve the above-mentioned technical problems, the solution adopted by this utility model is as follows: a novel outdoor anti-collision fire hydrant casting, including a fire hydrant body and an anti-collision plate. A fixed rod is provided on the fire hydrant body by a fixing device. A sliding rod is slidably passed through the fixed rod. The anti-collision plate is located at the end of the sliding rod. A damping device is provided between the fixed rod and the sliding rod. A return device is also provided between the fixed rod and the sliding rod to allow the sliding rod to return to its original position after sliding into the fixed rod.

[0007] A further improvement is made to the damping device, which includes a first damping block and a second damping block. The fixed rod has a damping channel that is connected to the sliding rod. One end of the damping channel has a connecting rod, and the first damping block is located at the end of the connecting rod. The other end of the damping channel has a rotating rod, and the second damping block is located on the rotating rod. The first damping block and the second damping block resist each other. The damping channel is equipped with a rotating device for driving the rotating rod to rotate.

[0008] A further improvement is that the rotating device includes a gear, which is sleeved on the rotating rod, and the sliding rod has a toothed row, which meshes with the toothed row for transmission.

[0009] A further improvement is that the return device is a spring, the fixed rod has a return channel, the fixed rod has a return plate and the return plate is located in the return channel, one end of the spring is connected to the return plate and the other end of the spring is connected to the inner wall of the return channel.

[0010] A further improvement is that the sliding rod is provided with a sliding rail, the fixed rod is provided with a sliding groove, and the sliding rail is slidably disposed in the sliding groove.

[0011] A further improvement is that the fixing device is a fixed rod that is threadedly connected to the fire hydrant body.

[0012] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0013] With a simple structure and anti-collision function, it can protect fire hydrants and extend their service life. The anti-collision plate allows vehicles to impact it first, thus protecting the fire hydrant and preventing damage and leakage, thereby reducing property loss. Attached Figure Description

[0017] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0018] refer to Figures 1-3 The present invention discloses a novel outdoor anti-collision fire hydrant casting, comprising a fire hydrant body 1 and an anti-collision plate 2. The fire hydrant body 1 is provided with a fixed rod 3, and a sliding rod 4 is slidably passed through the fixed rod 3. The anti-collision plate 2 is located at the end of the sliding rod 4. A damping device is provided between the fixed rod 3 and the sliding rod 4. A spring 7 is also provided between the fixed rod 3 and the sliding rod 4 to allow the sliding rod 4 to return to its original position after sliding into the fixed rod 3. The fixed rod 3 has a return channel 8, and a return plate 6 is provided on the fixed rod 3 and located in the return channel 8. One end of the spring 7 is connected to the return plate 6, and the other end of the spring 7 is connected to the inner wall of the return channel 8.

[0019] Specifically, the damping device includes a first damping block 13 and a second damping block 11. The fixed rod 3 has a damping channel 101 connected to the sliding rod 4. One end of the damping channel 101 has a connecting rod 12, and the first damping block 13 is located at the end of the connecting rod 12. The other end of the damping channel 101 has a rotating rod 10, and the second damping block 11 is located on the rotating rod 10. The first damping block 13 and the second damping block 11 resist each other. A gear 9 for driving the rotating rod 10 to rotate is provided inside the damping channel 101. The gear 9 is fixedly sleeved on the rotating rod 10. A gear rack is provided on the sliding rod 4, and the gear 9 meshes with the gear rack for transmission. In use, when a vehicle hits a fire hydrant, it first hits the crash barrier 2, thus protecting the fire hydrant and preventing damage and leakage, thereby reducing property damage. When the impact occurs, the anti-collision plate 2 causes the sliding rod 4 to slide into the fixed rod 3. At this time, the spring 7 is compressed, thus buffering the impact force. Simultaneously, the sliding rod 4 slides into the fixed rod 3, and the gear rack drives the gear 9 to rotate. The gear 9 drives the rotating rod 10 to rotate, and the rotating rod 10 drives the first damping block 13 to rotate. The first damping block 13 rubs against the second damping block 11, thereby further dissipating the impact force and reducing the impact force of the anti-collision plate 2. This reduces the destructive force after the impact, protecting not only the fire hydrant but also the anti-collision plate 2 and extending its service life.

[0020] In order to allow the sliding rod 4 to slide better, the sliding rod 4 is provided with a sliding rail 5, and the fixed rod 3 is provided with a sliding groove, and the sliding rail 5 is slidably disposed in the sliding groove.

[0021] In order to facilitate the removal of the fixing rod 3 and make it easier to connect the water hose during fire fighting, the fixing rod 3 is threadedly connected to the fire hydrant body 1.

[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions above are only illustrative of the principles of this utility model. Various changes and modifications may be made to this utility model without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
