Description

Technical Field

[0001] The utility model relates to the technical field of tunnel fire-fighting facilities, and particularly relates to a tunnel fire hydrant chamber structure. Background Art

[0002] With the increasing requirements for tunnel operation, there are more and more electromechanical facilities in the tunnel, and the installation of various facilities has requirements for equipment chambers and pipeline embedding. The relatively large chamber in the tunnel is the fire hydrant chamber. Due to the large number of fire-fighting equipment, a larger storage space is required. The main fire-fighting facilities include fire hydrants, fire hoses, sprinkler heads, foam boxes, valves, and fire extinguishers, etc. The existing fire hydrant chambers are made into long strip-shaped chambers arranged from left to right, and the fire-fighting equipment is also arranged in sequence from left to right in the fire hydrant chamber. In the tunnel, the designed size of the fire hydrant chamber is large and the setting interval is relatively dense. The designed size is 200*110*35cm, and the setting interval is 40m for three-lane tunnels and 50m for two-lane tunnels. In addition, the traditional method for constructing the reserved chamber is to manually break the secondary lining at the designed position of the reserved chamber after the tunnel secondary lining is completed to form the fire hydrant chamber. After the secondary lining is broken, the stress at the fire hydrant chamber will change, resulting in a risk of collapse of the secondary lining at the fire hydrant chamber.

[0003] In summary, there is an urgent need for a tunnel fire hydrant chamber structure to solve or at least partially solve the problems existing in the prior art. Content of the Utility Model

[0004] The purpose of the utility model is to provide a tunnel fire hydrant chamber structure, aiming to solve the problem that the existing fire hydrant needs to break out the fire hydrant chamber structure on the cast secondary lining, which is likely to cause the instability of the secondary lining at the fire hydrant chamber. The specific technical solution is as follows:

[0005] A tunnel fire hydrant chamber structure includes a pre-embedded box body.

The lamp is arranged on the inner side wall of the embedded box body, the power source is arranged in the second cavity of the embedded box body, and the switch is installed at the opening of the embedded box body. When the sliding door is closed, the sliding door presses on the switch and the switch is turned off. When the sliding door is opened, the sliding door moves away from the switch and the switch is turned on.

[0010] Preferably, the sliding door includes a door body, a locking mechanism, and two sliding rails arranged in parallel with each other. The two sliding rails are respectively detachably connected to the upper and lower edges on one side of the opening of the embedded box body. The door body is slidably connected to the two sliding rails. The locking mechanism is installed on the door body and is used to lock and unlock the door body with the sliding rails.

[0011] Preferably, the locking mechanism includes a driving component, a locking tongue, and a resilient member. A receiving cavity is provided in the door body, and the upper and lower ends of the receiving cavity are respectively open. There are two locking tongues and two resilient members. The two locking tongues are both slidably connected in the receiving cavity. The two resilient members are arranged in the receiving cavity. The resilient members are arranged in one-to-one correspondence with the locking tongues. One end of the resilient member abuts against the locking tongue, and the other end of the resilient member abuts against the inner wall of the receiving cavity.

[0029] For the convenience of understanding the present utility model, the present utility model will be described more comprehensively below, and preferred embodiments of the present utility model are given. However, the present utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure content of the present utility model more thorough and comprehensive.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0031] Embodiment:

[0032] See Figures 1-7 , this embodiment provides a tunnel fire hydrant chamber structure, including an embedded box 1. One side of the embedded box 1 is open, and the open side of the embedded box 1 faces the inside of the tunnel 6. The embedded box 1 includes a first cavity 11 and a second cavity 12. The first cavity 11 and the second cavity 12 are arranged up and down, and the first cavity 11 and the second cavity 12 are separated by a bearing plate 2. A first through hole 13 is arranged at the bottom of the embedded box 1, and a second through hole 21 is arranged on the bearing plate 2.

[0033] It is found through research that the existing method of chiseling on the second lining after pouring is likely to damage the overall structural strength of the second lining that has already solidified. When chiseling out the chamber structure of the fire hydrant from the second lining, the internal stress of the second lining will change, reducing the overall strength and waterproof performance of the second lining. Secondly, the existing fire hydrant chamber structures are all arranged along the length direction of the tunnel 6. After chiseling out the fire hydrant chamber structure, the upper part of the long fire hydrant chamber structure loses support, which has a greater impact on the second lining.

[0034] It is understandable that the embedded box body 1 is embedded to form a fire hydrant chamber structure inside the box body. Secondly, by arranging the embedded box body 1 into a first cavity 11 and a second cavity 12 arranged up and down, the overall width of the fire hydrant chamber structure is reduced, and the area of the second lining spanning across the air above the fire hydrant chamber structure is reduced, thereby reducing the damage to the strength of the second lining to a certain extent and preventing the instability of the fire hydrant chamber structure. On the other hand, through the embedded pouring method, the second lining is more tightly combined with the embedded box body 1. To a certain extent, the top of the embedded box body 1 plays a supporting role for the second lining, enhancing the stability of the second lining; secondly, by adopting the structural form of the embedded box body 1, the waterproof performance of the fire hydrant chamber structure is better. The first through hole 13 and the second through hole 21 are used for the fire pipeline to pass through, facilitating the installation of the fire pipeline in the later stage. The bearing plate 2 is a pull-out plate, which can be pulled out first when installing the fire pipeline, and then the bearing plate 2 is installed after the installation is completed, facilitating the installation of the fire pipeline.

[0035] Preferably, an installation frame 14 is arranged in the first cavity 11, and the installation frame 14 is detachably connected to the inner wall of the first cavity 11.

[0036] Specifically, the installation frame 14 is detachably connected to the inside of the embedded box body 1 through bolts. Fire fighting supplies such as foam boxes and water pipes connecting fire hydrants can be conveniently installed through the installation frame 14.

[0037] Preferably, a clamp 15 for installing a fire extinguisher is arranged in the second cavity 12, and the clamp 15 is detachably connected to the inner wall of the second cavity 12.

[0038] It is understandable that the fire extinguisher in the second cavity 12 is fixed by the fire clamp 15. The fire clamp 15 is a clamp 15 that can be quickly disassembled, facilitating fixation during storage and enabling quick removal during retrieval.

[0039] Furthermore, it further includes a sliding door 3 that is detachably connected, and the sliding door 3 is arranged at the opening of the embedded box body 1.

[0040] It is understandable that when there is a car accident or other situations in the tunnel 6, the tunnel 6 is often crowded with accident vehicles. If a rotating door is used, due to the obstruction of the vehicles, the fire door cannot be opened smoothly. However, when using the sliding door 3, the occupied area is reduced when opening, so that the sliding door 3 can be opened smoothly, facilitating the retrieval of fire fighting facilities for fire extinguishing operations.

[0041] Further, it further includes a lighting mechanism 4. The lighting mechanism 4 includes a switch 41, a power supply 42, and a lamp 43. The lamp 43 is electrically connected to the power supply 42 through the switch 41. The lamp 43 is arranged on the inner side wall of the embedded box body 1, the power supply 42 is arranged in the second cavity 12 of the embedded box body 1, and the switch 41 is installed at the opening of the embedded box body 1. When the sliding door 3 is closed, the sliding door 3 presses on the switch 41, and the switch 41 is turned off. When the sliding door 3 is opened, the sliding door 3 moves away from the switch 41, and the switch 41 is turned on.

[0042] Specifically, the switch 41 is a push switch 41. When the switch 41 is pressed down, the switch 41 is turned off. When the switch 41 bounces up, the switch 41 is turned on. The upper surface of the switch 41 is an arc surface or an inclined surface facing the sliding door 3. When the sliding door 3 moves towards the switch 41, under the guiding action of the arc surface or the inclined surface, the sliding door 3 can press on the switch 41 to turn off the switch 41. When the sliding door 3 is moved away, the switch 41 automatically bounces up and is turned on. The lamp 43 is installed on the side wall of the first cavity 11, and the bearing plate 2 is provided with a plurality of light-transmitting holes.

[0043] It can be understood that the tunnel 6 is generally dim, especially when accidents such as car accidents occur. The power facilities in the tunnel 6 may also malfunction, resulting in a lower visibility in the tunnel 6, making it inconvenient to take fire-fighting facilities. In particular, the fire hose needs to be connected to the fire hydrant, and it is very difficult for ordinary people to connect in the dark. Through the setting of the lighting mechanism 4, when the sliding door 3 is opened, the switch 41 pressed by the sliding door 3 bounces up. At this time, the switch 41 is turned on, and the power supply 42 is connected to the lamp 43 through the switch 41 to turn on the lamp 43 to illuminate the first cavity 11, thus facilitating the taking and connection of the fire-fighting facilities in the first cavity 11. In addition, by providing light-transmitting holes on the bearing plate 2, when the lamp 43 is turned on, the light is irradiated into the second cavity 12 through the light-transmitting holes to illuminate the second cavity 12, facilitating the taking and operation of fire-fighting facilities such as fire extinguishers in the second cavity 12. In addition, the lamp 43 can also play a role in temporarily illuminating the tunnel 6. When it is necessary to turn off the lamp 43, just close the sliding door 3, and the sliding door 3 will press down the switch 41, so that the switch 41 is turned off and the lamp 43 goes out. It is powered by the power supply 42 in the second cavity 12, and when the external circuit is powered off, the lighting mechanism 4 can still work normally without being affected by the outside.

[0044] Preferably, the sliding door 3 includes a door body 31, a locking mechanism 32, and two mutually parallel slide rails 33. The two slide rails 33 are respectively detachably connected to the upper and lower edges on one side of the opening of the embedded box body 1. The door body 31 is slidably connected to the two slide rails 33. The locking mechanism 32 is installed on the door body 31 and is used to lock and unlock the door body 31 and the slide rails 33.

[0045] The locking mechanism 32 includes a driving component 321, a locking tongue 322 and a resilient member 323. A receiving cavity 311 is provided in the door body 31, and both the upper and lower ends of the receiving cavity 311 are open. Two locking tongues 322 and two resilient members 323 are arranged. The two locking tongues 322 are both slidably connected in the receiving cavity 311, and the two resilient members 323 are arranged in the receiving cavity 311. The resilient members 323 are arranged in one-to-one correspondence with the locking tongues 322. One end of the resilient member 323 abuts against the locking tongue 322, and the other end of the resilient member 323 abuts against the inner wall of the receiving cavity 311. A locking hole 331 is arranged on one side of the slide rail 33 corresponding to the opening of the receiving cavity 311. The driving component 321 is used to drive the locking tongue 322 to penetrate into and out of the locking hole 331.

[0046] Specifically, the driving component 321 is a manual driving component 321.

[0047] It can be understood that when manually driving the driving mechanism to act, when the driving component 321 drives the locking tongue 322 to retract into the receiving cavity 311, the resilient member 323 is compressed, and the locking mechanism 32 is unlocked. When the hand is released, the locking tongue 322 is reset under the elastic force of the resilient member 323 and is locked again. In this embodiment, the resilient member 323 is a spring. In some other embodiments, the resilient member 323 can also be a rubber spring, a gas spring or other structures or components that can store elastic potential energy.

[0048] Of course, in some other embodiments, the driving component 321 can also drive the locking tongue 322 to move by an electric driving method.

[0049] Preferably, a plurality of locking holes 331 are arranged, and the plurality of locking holes 331 are arranged along the length direction of the slide rail 33.

[0050] It can be understood that by arranging a plurality of locking holes 331 on the slide rail 33, the sliding door 3 can be limited at any position corresponding to any of the locking holes 331 on the slide rail 33. Thus, the sliding door 3 can be limited at the docking position to prevent the sliding door 3 from sliding randomly and affecting the operation of taking the fire-fighting facilities.

[0051] As a preferred embodiment, the driving component 321 includes a handle 3211, a gear 3212 and a rack 3213. The handle 3211 is rotatably connected to the door body 31. The gear 3212 is arranged in the receiving cavity 311 and is fixedly connected to the handle 3211. Two racks 3213 are arranged, and the two racks 3213 are slidably connected in the receiving cavity 311. The two racks 3213 are both meshed with the gear 3212, and the two racks 3213 are respectively connected to the two locking tongues 322.

[0052] Specifically, refer to Figure 3, when moving the driving handle towards the right, it will drive the handle to rotate clockwise. The handle drives the turntable 3214 to rotate and wind the pull wire 3215, so that the pull wire 3215 pulls the lock tongue 322 to retract into the accommodating cavity 311. During the process of the lock tongue 322 retracting into the accommodating cavity 311, it compresses the elastic member 323 and withdraws the lock tongue 322 from the lock hole 331 in the slide rail 33. At this time, the sliding door 3 is unlocked and can slide back and forth along the slide rail 33 conveniently. When the handle 3211 is released, the lock tongue 322 resets under the elastic action of the elastic member 323 and re-inserts into the lock hole 331 on the slide rail 33, and the position of the sliding door 3 relative to the slide rail 33 is locked.

[0053] As another preferred embodiment, the driving assembly 321 includes a handle 3211, a turntable 3214 and a pull wire 3215. The handle 3211 is rotatably connected to the door body 31. The turntable 3214 is arranged in the accommodating cavity 311 and is fixedly connected to the handle 3211. Two pull wires 3215 are arranged, and the two pull wires 3215 are respectively arranged corresponding to the two lock tongues 322. The first end of the pull wire 3215 is fixedly connected to the turntable 3214, and the other end of the pull wire 3215 is fixedly connected to the lock tongue 322.

[0054] Specifically, referring to Figure 5 , when moving the driving handle towards the right, it will drive the handle to rotate clockwise. The handle drives the gear 3212 to rotate, and the gear 3212 drives the rack 3213 to move, so that the lock tongue 322 retracts into the accommodating cavity 311. During the process of the lock tongue 322 retracting into the accommodating cavity 311, it compresses the elastic member 323 and withdraws the lock tongue 322 from the lock hole 331 in the slide rail 33. At this time, the sliding door 3 is unlocked and can slide back and forth along the slide rail 33 conveniently. When the handle 3211 is released, the lock tongue 322 resets under the elastic action of the elastic member 323 and re-inserts into the lock hole 331 on the slide rail 33, and the position of the sliding door 3 relative to the slide rail 33 is locked.

[0055] The construction process of the present utility model is as follows:

[0056] Before pouring the second lining, place the embedded box body 1 into the pouring mold of the second lining and fix the embedded box body 1. Use a plugging block to plug the first through hole 13 of the embedded box body 1 to prevent concrete from entering the embedded box body 1 from the first through hole 13 during the pouring process. The plugging block can be items such as a rubber block or a felt cloth, which is convenient for smooth demolding. A leak-proof rubber strip is padded between the open end of the embedded box body 1 and the template of the second lining to prevent concrete from entering the embedded box body 1 from the opening. After the concrete is poured, install the two guide rails at the opening of the embedded box body 1, and install the sliding door 3 and other components inside the embedded box body 1.

[0057] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
