Description

Technical Field

[0001] This utility model relates to the field of fire hydrant technology for fire protection engineering, specifically a fire hydrant for fire protection engineering. Background Technology

[0002] Fire hydrants in fire protection engineering are specialized fire-fighting water supply devices that are fixedly installed inside and outside buildings or on municipal fire protection pipe networks. They typically consist of a hydrant body, valve, outlet, interface, and pressure device, and are divided into indoor fire hydrants and outdoor fire hydrants. Their function is to provide firefighters or trained personnel with an interface for quickly connecting fire hoses and spraying high-pressure water for fire extinguishing. They are key facilities for extinguishing initial fires. Outdoor fire hydrants are mostly designed underground or above ground, equipped with standard 65mm or 80mm interfaces, and are regularly maintained to ensure normal use during fires.

[0003] Outdoor fire hydrants are often installed on both sides of roads and other areas, making them susceptible to damage from vehicle collisions. Common protective measures include the installation of crash barriers. However, existing barriers are often rigidly fixed, which, while providing impact protection, may obstruct the operating space of the hydrant, making it difficult for firefighters to connect hoses or operate wrenches. The barriers may also hinder emergency operations. Furthermore, if the protective measures are not designed properly, they may actually impede the rapid activation of the fire hydrant, delaying the opportunity to extinguish the fire. Therefore, we propose a fire hydrant for fire protection engineering. Utility Model Content

[0004] The purpose of this utility model is to provide a fire hydrant for fire protection engineering to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fire hydrant for fire protection engineering, comprising a base, a fire hydrant body mounted on the surface of the base, a protective structure provided on the surface of the base, the protective structure comprising a column, a fixed shaft fixedly connected to both sides of the column, a torsion spring sleeved on the arc surface of the fixed shaft, a protective cover rotatably connected to both ends of the fixed shaft, both ends of the torsion spring being fixedly connected to the column and the protective cover respectively, an extension plate fixedly connected to the surface of the protective cover, a rope fixedly connected to the surfaces of the two extension plates, a bracket fixedly connected to the surface of the column, the rope passing through the bracket, and a pull ring fixedly connected to one end of the rope.

[0006] The effect achieved by the above-mentioned components is that by setting up a protective structure, a protective cover that is easy to use and open can be used to protect the fire hydrant, so that it can be quickly activated when using the fire hydrant body, thereby avoiding delays in extinguishing the fire.

[0007] Preferably, the surface of the rope is fitted with rollers, and the rollers are rotatably connected to the bracket.

[0008] The effect achieved by the above components is that the presence of rollers reduces the friction when the rope moves, making the operation easier and smoother.

[0009] Preferably, the surface of the bracket is fixedly connected with a hook.

[0010] The effect achieved by the above components is to allow the pull ring to be hooked onto the hook, thereby avoiding the need to keep the pull ring pulled when using the fire hydrant body.

[0011] Preferably, a top cover is fixedly connected to the surface of the protective cover, and the vertical cross-section of the top cover is conical.

[0012] The aforementioned components achieve the following effects: they effectively prevent rainwater from dripping onto the surface of the fire hydrant, avoiding rust and corrosion caused by long-term water accumulation. When rainwater falls on the top cover, it will quickly slide down the conical surface, ensuring the overall dryness of the fire hydrant structure. At the same time, the top cover can also prevent dust, leaves, and other debris from falling onto the surface of the fire hydrant, preventing these debris from clogging the fire hydrant's interfaces or valves, and ensuring that the fire hydrant can be used normally in an emergency.

[0013] Preferably, a water guide box is fixedly connected to the surface of the protective cover, and the water guide box is attached to the connection between the top cover and the protective cover.

[0014] The effect achieved by the above components is that when rainwater slides down the top cover, the water guide box can guide the rainwater to flow down in a specific direction, allowing the rainwater to flow to a designated location, such as a drainage pipe or sewer, to avoid water accumulation on the ground. This can reduce the trouble caused by water accumulation when people go out, prevent slipping and falling, and also prevent vehicles from being damaged when driving in water.

[0015] Preferably, a protective pad is fixedly connected to the surface of the protective cover, and the protective pad is made of rubber.

[0016] The effect achieved by the above components is that the protective pads prevent hard contact between the protective covers, thus avoiding damage or deformation to the protective covers.

[0017] Preferably, the inner wall of the protective cover is fixedly connected with several ribs.

[0018] The effect achieved by the above components is that the several ribs fixedly connected to the inner wall of the protective cover enhance the structural strength of the protective cover, making it less prone to deformation when subjected to impact, better protecting the fire hydrant body, and ensuring that the fire hydrant can be used normally in emergency situations.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This utility model features a torsion spring whose two ends are fixedly connected to a column and a protective cover, respectively. Under the torsion of the torsion spring, the protective cover tightly wraps around the fire hydrant body. This design can effectively prevent damage to the fire hydrant caused by accidental collisions with vehicles during daily driving. When the fire hydrant needs to be used for fire extinguishing, the pull ring is pulled to open the protective cover. The easily opened protective cover protects the fire hydrant, allowing it to be quickly activated when the fire hydrant body is used, thus avoiding delays in extinguishing the fire.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-2This utility model provides a technical solution: a fire hydrant for fire protection engineering, including a base 1, a fire hydrant body 2 mounted on the surface of the base 1, a protective structure 3 on the surface of the base 1, the protective structure 3 including a column 301, a fixed shaft 302 fixedly connected to both sides of the column 301, a torsion spring 303 sleeved on the arc surface of the fixed shaft 302, a protective cover 304 rotatably connected to both ends of the fixed shaft 302, the two ends of the torsion spring 303 being fixedly connected to the column 301 and the protective cover 304 respectively, an extension plate 305 fixedly connected to the surface of the protective cover 304, a rope 306 fixedly connected to the surface of the two extension plates 305, a bracket 308 fixedly connected to the surface of the column 301, the rope 306 passing through the bracket 308, and a pull ring 307 fixedly connected to one end of the rope 306. By setting the protective structure 3, the protective cover 304, which is easy to use and open, protects the fire hydrant, so that it can be quickly activated when using the fire hydrant body 2, thereby avoiding delays in extinguishing the fire.

[0029] Reference Figure 3 and Figure 4 and Figure 5As shown in this embodiment: A roller 309 is fitted onto the surface of the rope 306. The roller 309 is rotatably connected to the bracket 308. The presence of the roller 309 reduces the friction when the rope 306 moves, making operation easier and smoother. A hook 310 is fixedly connected to the surface of the bracket 308. The pull ring 307 is hung on the hook 310, thus avoiding the need to keep pulling the pull ring 307 when using the fire hydrant body 2. A top cover 311 is fixedly connected to the surface of the protective cover 304. The vertical cross-section of the top cover 311 is conical, which effectively prevents rainwater from dripping onto the surface of the fire hydrant, avoiding rust and corrosion caused by long-term water accumulation. When rainwater falls on the top cover 311, it will quickly slide off the conical surface, ensuring the dryness of the overall structure of the fire hydrant. At the same time, the top cover 311 can also prevent dust, leaves, and other debris from falling onto the surface of the fire hydrant, preventing these debris from clogging the fire hydrant's interfaces or valves, ensuring that the fire hydrant can be used normally in emergencies. A water guide box 312 is fixedly connected to the surface of the protective cover 304. The water guide box 312 is attached to the connection between the top cover 311 and the protective cover 304. When rainwater slides down the top cover 311, the water guide box 312 can guide the rainwater to flow down in a specific direction, allowing the rainwater to flow to a designated location, such as a drainage pipe or sewer, to avoid water accumulation on the ground. This reduces the inconvenience of people being troubled by water accumulation when traveling, prevents slips and falls, and also prevents vehicles from being damaged when driving in water. A protective pad 313 is fixedly connected to the surface of the protective cover 304. The protective pad 313 is made of rubber and serves to prevent hard contact between the protective covers 304, which could cause damage or deformation to the protective cover 304. The inner wall of the protective cover 304 is fixedly connected with several ribs 314. The ribs 314 fixedly connected to the inner wall of the protective cover 304 enhance the structural strength of the protective cover 304, making it less prone to deformation when subjected to impact, better protecting the fire hydrant body 2, and ensuring that the fire hydrant can be used normally in emergency situations.

[0030] Working Principle: Under normal conditions, the torsion spring 303 in the protective structure 3 plays a crucial role. The two ends of the torsion spring 303 are fixedly connected to the column 301 and the protective cover 304, respectively. Under the torsion of the torsion spring 303, the protective cover 304 tightly wraps around the fire hydrant body 2. This design effectively prevents damage to the fire hydrant caused by accidental collisions with vehicles during normal driving. When the fire hydrant needs to be used for firefighting, the operator pulls the pull ring 307. The pull ring 307 moves the rope 306. The roller 309 on the surface of the rope 306 is rotatably connected to the bracket 308. The presence of the roller 309 reduces the friction of the rope 306 during movement, making operation easier. With ease and smoothness, as the rope 306 moves, the protective cover 304 rotates around the fixed shaft 302, overcoming the torque of the torsion spring 303 to open. At this time, the fire hydrant body 2 is fully exposed, facilitating firefighters to quickly connect the fire hose and carry out firefighting operations. Then, the pull ring 307 is hooked onto the hook 310, thus avoiding the need to keep pulling the pull ring 307 while using the fire hydrant body 2. After use, the pull ring 307 is released, and under the torque of the torsion spring 303, the protective cover 304 automatically returns to its original position, re-wrapping the fire hydrant body 2. When the protective cover 304 returns to its original position, one side of the two protective covers 304 will rotate towards each other until the two protective covers 304... The protective pads 313 on the surface of the 04 are tightly fitted together, preventing hard contact between the protective covers 304 and thus avoiding damage or deformation to the protective covers 304. Several ribs 314 fixedly connected to the inner wall of the protective cover 304 enhance the structural strength of the protective cover 304, making it less prone to deformation when subjected to impact, better protecting the fire hydrant body 2, and ensuring that the fire hydrant can be used normally in emergency situations. The top cover 311 has a tapered vertical section. This special shape design plays a key role in the daily use of the fire hydrant. It can effectively prevent rainwater from dripping onto the surface of the fire hydrant, avoiding rust and corrosion caused by long-term water accumulation. When rainwater falls on the top cover 311, it will quickly slide down the conical surface, ensuring the dryness of the entire fire hydrant structure. At the same time, the top cover 311 can also prevent dust, leaves and other debris from falling on the surface of the fire hydrant, preventing these debris from clogging the fire hydrant's interfaces or valves, ensuring that the fire hydrant can be used normally in emergencies. When rainwater slides down the top cover 311, the water guide box 312 can guide the rainwater to flow down in a specific direction, allowing the rainwater to flow to a designated location, such as a drainage pipe or sewer, to avoid water accumulation on the ground. This can reduce the trouble caused by water accumulation when people go out, prevent slipping and falling, and also prevent vehicles from being damaged when driving in water.
