Description

Technical Field

[0001] This utility model relates to the field of outdoor fire hydrant anti-collision structure technology, specifically an outdoor fire hydrant with an elastic anti-collision structure. Background Technology

[0002] Outdoor fire hydrants are water supply facilities installed on the fire water supply network outside buildings. They primarily allow fire trucks to draw water from the municipal water supply network or the outdoor fire water supply network for firefighting. They can also be directly connected to fire hoses and nozzles for firefighting. Therefore, the outdoor fire hydrant system is one of the important fire-fighting facilities for extinguishing fires.

[0003] Existing technology disclosure number CN222413251U discloses an outdoor fire hydrant with protective function, belonging to the field of fire hydrant technology. It includes a fire hydrant body with two semi-circular fixing plates on its outer side. The lower part of each semi-circular fixing plate is fixedly connected to a semi-circular ring. Two fixing blocks are provided at both ends of the semi-circular fixing plate on the side away from the fire hydrant body. Two fixing blocks on the same side of the semi-circular fixing plate are fixedly connected by a fixing rod. Each end of the fixing rod has a movable block, which is movably connected to a connecting rod. The side of the connecting rod away from the movable block is movably connected to a connecting block. Two connecting blocks on the same side of the semi-circular fixing plate are fixedly connected to a crash barrier. A spring is sleeved between the two movable blocks on the fixing rod. The spring's cushioning effectively buffers the impact on the fire hydrant, significantly improving its safety.

[0004] While the above-mentioned methods offer certain advantages in improving security, they also have some drawbacks.

[0005] 1. The installation of crash barriers and fire hydrants is relatively complicated, requiring multiple bolts for fixing.

Triangular plates 22 are fixedly connected to the inner side walls of the left and right ends of the pressing cylinder 21. A return spring 23 is fixedly connected to the center of the top inner surface of the pressing cylinder 21. A limiting cylinder is provided at the center of the bottom inner surface of the second limiting block 160, and a connecting rod 24 is slidably connected through the limiting cylinder.

The toothed groove 27 is meshed with a gear 29, and the gear 29 is fixedly connected to the second connecting column 17.

[0030] The working principle of an outdoor fire hydrant with an elastic anti-collision structure based on Embodiment 1 is as follows:

[0031] First, during installation, manually pick up the anti-collision device 5, then lay it flat, align the first semi-circular fixing block 15 with the sliding groove 32, and then slide it into the inner side of the mounting groove 31 along with the second connecting plate 14. At the same time, make the first semi-circular fixing block 15 and the second semi-circular fixing plate 33 fit together to form a circle. After completion, use the first semi-circular fixing block 15 and the second semi-circular fixing plate 33 as relative fulcrums to rotate the anti-collision device 5 to make it vertically upright.

[0032] Second, during the alignment process, manually pressing the pressing cylinder 21 drives the triangular plate 22 to move the Z-shaped plate 25 through the inclined plane. At the same time, the connecting rod 24 moves relative to the moving rod, and the return spring 23 is squeezed. The frame plate 26 moves through the second inclined tooth groove 30 and the first inclined tooth groove 28. The gear 29 is driven by the tooth groove 27 to drive the second connecting column 17 and the rotating roller 18 to rotate together. The pull rope 20 is wrapped around the pull block 19 and at the same time, the locking block 19 is moved and retracted to the inside of the first limiting block 16.

[0033] Third, when the anti-collision device 5 is positioned correctly, the first limiting block 16 at the top is inserted into the inner side of the limiting port 6. Then, the pressing cylinder 21 is released, and the locking block 19 moves into the inner side of the locking port 7 through the spring reset. This completes the installation without the need for additional parts. When the anti-collision device 5 is subjected to external force, the anti-collision arc plate 9 drives the first connecting column 8 to move and pushes the partition plate 10 to move. If the force is small, it can be absorbed by the first spring 11 through stretching, which can also provide initial protection. When the impact force is large, the partition plate 10 squeezes the main spring 13, which can also absorb the force. When the anti-collision device 5 is damaged, the pressing cylinder 21 can be pressed again, and the anti-collision device 5 can be rotated to rotate the first semi-circular fixing block 15 and the second semi-circular fixing plate 33 to the initial flat position. The damaged anti-collision device 5 can also be removed for easy replacement.

[0034] This utility model provides an improved outdoor fire hydrant with an elastic anti-collision structure. In use, the anti-collision device 5 is laid flat, and the first semi-circular fixing block 15 is aligned with the sliding groove 32. The second connecting plate 14 is then slidably inserted into the mounting groove 31, causing the first semi-circular fixing block 15 and the second semi-circular fixing plate 33 to fit together and form a circle. The anti-collision device 5 is then rotated vertically, and the first semi-circular fixing block 15 drives the second semi-circular fixing plate 33 to rotate together, creating a relative misalignment with the sliding groove 32. Simultaneously, the pressing cylinder 21 is pressed, causing the locking block 19 to retract. When the first limiting block 16 engages inside the limiting port 6, the pressing cylinder 21 is released, and the locking block 19 engages inside the locking slot 7, allowing for quick installation without additional parts. Conversely, it can also be quickly disassembled.
