Description

Technical Field

[0001] This utility model relates to the field of fire protection technology, and in particular to a fire hydrant box for tunnels. Background Technology

[0002] A fire hydrant box is a fixed device used to store and protect fire hydrants and related equipment. It is usually installed on the wall inside a building. It is an important fire protection facility designed to provide a rapid and effective means of extinguishing fires, especially in the early stages of a fire, and can greatly reduce the losses and risk of casualties caused by fires.

[0003] Existing fire extinguisher boxes typically have doors made of glass and metal frames, and are mostly designed with a flat structure to ensure quick opening and unobstructed access to equipment in an emergency. However, in special environments such as tunnels, fire extinguisher boxes may be designed to conform to the curves of the tunnel sidewalls in order to blend in with the environment, including the door adopting an arc design. While this design improves aesthetics and space utilization efficiency, it also brings new challenges.

[0004] Specifically, when the fire cabinet door opens to the sides, due to its curved design and limited opening angle, the glass section is prone to colliding with the tunnel wall or other structures when opened by staff. Such collisions may cause uneven stress on the corners of the glass, leading to breakage and damage. This not only increases maintenance costs but may also hinder the rapid access of fire-fighting equipment in emergencies and even pose a risk of injury to users. Furthermore, if the glass breaks, it will reduce the protective effect of the fire cabinet on the internal equipment, exposing it to dust, moisture, and other potential damaging factors, affecting the long-term performance and reliability of the equipment. Therefore, to address this issue, it is necessary to consider improving the design or taking additional safety measures to prevent such accidents from occurring. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a tunnel fire hydrant box.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fire hydrant box for tunnels includes a fire hydrant box and a door adapted to the shape of the tunnel sidewall. Two mounting plates are fixed to the top of the sidewall of the fire hydrant box, and a fixing shaft is fixed between the two mounting plates. A mounting bracket is rotatably mounted on the fixing shaft. The mounting bracket is fixed to the top of the door. Electric telescopic rods are rotatably connected to both inner sides of the fire hydrant box. The telescopic ends of the electric telescopic rods are rotatably connected to the back of the door. A protective component is provided between the fire hydrant box and the door.

[0008] As a preferred technical solution of this utility model, the protective component includes a slot disposed on the side wall of the fire box and facing the box door. The slot is provided with a buffer pad, the buffer pad is hollow inside, and the buffer pad is provided with several springs inside.

[0009] As a preferred embodiment of this utility model, the cross-section of one side of the buffer pad is I-shaped, and the cross-section of one side of the slot is T-shaped.

[0010] As a preferred embodiment of this utility model, the buffer pad has an inclined surface on the side wall facing the slot.

[0011] As a preferred embodiment of this utility model, the fire box is provided with a lubrication assembly, which includes a sealed cylinder fixedly connected to the inside of the fire box for storing lubricating fluid. A sliding plug is slidably connected inside the sealed cylinder, and the lubricating fluid is located on one side of the sliding plug. An air inlet pipe and an air outlet pipe are connected to the buffer pad. Both the air inlet pipe and the air outlet pipe are provided with one-way valves, and the flow limiting directions of the two one-way valves are opposite. The air outlet pipe is connected to one end of the sealed cylinder, and the other end of the sealed cylinder is connected to a liquid outlet pipe, which is located on the side closer to the lubricating fluid. The fixed shaft is hollow inside, and several through holes are opened on the fixed shaft, and the through holes are connected to the inside of the fixed shaft. The liquid outlet pipe is connected to the inside of the fixed shaft.

[0012] As a preferred embodiment of this utility model, all the through holes are arranged at equal intervals.

[0013] This utility model has the following beneficial effects:

[0014] 1. Preventing damage: The door can rotate upwards via an electric telescopic rod, which prevents the door from colliding with the tunnel during opening and causing damage. In addition, the two symmetrically arranged electric telescopic rods in the design ensure that the force on both sides is even when the door rotates upwards, avoiding the problem of glass breakage caused by uneven force. This design enhances the safety and reliability of the equipment.

[0015] 2. Quick opening: The electric telescopic rod is connected to the fire alarm system and can be automatically activated when a fire is detected, so that the door can be opened quickly, which improves the emergency response speed and reduces the time and complexity of manual operation.

[0016] 3. The protective components provide cushioning protection: The protective components installed between the door and the fire box not only absorb the impact force when closing, but also ensure the airtightness of the fire box, further protecting the internal fire equipment from the influence of the external environment, reducing maintenance costs. In addition, the special design of the buffer pad and the slot facilitates the connection between the two, which makes it easier for staff to install and maintain, simplifies daily inspection and maintenance work, and reduces long-term operating costs.

[0017] 4. Lubrication system improves durability: The presence of lubrication components ensures smooth rotation between the fixed shaft and the mounting bracket, reduces friction, extends the service life of mechanical parts, and also ensures the smoothness and reliability of the door opening and closing action.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] Reference Figure 1-5A fire hydrant box for tunnels includes a fire hydrant box 1 adapted to the shape of the tunnel sidewall and a box door 2. Both the opening of the fire hydrant box 1 and the box door 2 are rectangular. The box door 2 is constructed of a metal frame and glass. Two mounting plates 3 are fixed to the top of the sidewall of the fire hydrant box 1 and welded to it. A fixing shaft 4 is fixed between the two mounting plates 3. A mounting bracket 5 is rotatably mounted on the fixing shaft 4 and fixed to the top of the box door 2 by welding. Electric telescopic rods 16 are rotatably connected to both inner sides of the fire hydrant box 1. The telescopic ends of the electric telescopic rods 16 are connected to the back of the box door 2. Specifically, a connecting plate is welded and fixed to the back of the door 2. The telescopic end of the electric telescopic rod 16 is rotatably connected to the side wall of the connecting plate. The two electric telescopic rods 16 are symmetrically arranged, so that the force on both sides is even when the door 2 rotates upward. Furthermore, the electric telescopic rod 16 is connected to the fire alarm system. When a fire is detected, the electric telescopic rod 16 can be automatically activated, so that the door 2 can be opened quickly. Optionally, the switch of the electric telescopic rod 16 can be set on the tunnel side wall. The user can open it by pressing the switch, which replaces the manual opening method and can improve the opening efficiency.

[0027] A protective assembly is installed between the fire box 1 and the door 2. The protective assembly includes a slot 6 located on the side wall of the fire box 1, directly opposite the door 2. The slot 6 contains a buffer pad 7. When the door 2 is closed, the buffer pad 7 can absorb the impact force of the door 2 hitting the fire box 1, thus preventing damage to the glass of the door 2 due to uneven force. Secondly, when the door 2 is closed, the buffer pad 7 can fill the gap between the door 2 and the fire box 1, ensuring the airtightness of the fire box 1, thus protecting the fire equipment inside the fire box 1. The buffer pad 7 is hollow inside and contains several springs 15, which assist the buffer pad 7 in restoring its shape. One side of the buffer pad 7 has an I-shaped cross-section, and the other side of the slot 6 has a T-shaped cross-section. This design facilitates the installation of the buffer pad 7 into the slot 6, thereby facilitating the maintenance of the fire box 1 by staff. The side wall of the buffer pad 7 facing the slot 6 has a slope, which facilitates the insertion of part of the buffer pad 7 into the slot 6.

[0028] Working principle: When a fire occurs and fire-fighting equipment needs to be used, the fire alarm system or the user activates the electric telescopic rod 16 via a switch. The telescopic end of the electric telescopic rod 16 extends and pushes the box door 2 upward, allowing the box door 2 and the mounting bracket 5 to rotate upward. At the same time, the electric telescopic rod 16 also rotates, so that the box door 2 can be opened quickly without colliding with the tunnel wall during the opening process, thus preventing damage to the equipment. Conversely, when closing, the telescopic end of the electric telescopic rod 16 retracts and pulls the box door 2 in reverse to reset. At the same time, the buffer pad 7 cushions the box door 2, further preventing damage to the equipment.

[0029] Example 2

[0030] Example 2 includes the content of Example 1. The technical features disclosed in Example 1 are also applicable to this example. The technical features disclosed in Example 1 will not be described again in the specification. The implementation method of the tunnel fire hydrant box will be further described in detail below with reference to the accompanying drawings.

[0031] Reference Figure 3 and Figure 4 The fire box 1 is equipped with a lubrication assembly, which includes a sealed cylinder 11 fixedly connected to the inside of the fire box 1 for storing lubricating fluid. A sliding plug 13 is slidably connected inside the sealed cylinder 11, with the lubricating fluid located on one side of the sliding plug 13. An air inlet pipe 8 and an air outlet pipe 9 are connected to a buffer pad 7. Both the air inlet pipe 8 and the air outlet pipe 9 are equipped with one-way valves 10, and the flow restriction directions of the two one-way valves 10 are opposite. Under the action of the one-way valves 10, when the buffer pad 7 is compressed, the air inside it will enter the sealed cylinder 11. When the buffer pad 7 is restored, outside air can enter it through the air inlet pipe 8. The air outlet pipe 9 is connected to one end of the sealing cylinder 11, and the other end of the sealing cylinder 11 is connected to the liquid outlet pipe 12, which is located on the side close to the lubricant. The interior of the fixed shaft 4 is hollow, and several through holes 14 are opened on the fixed shaft 4, which are connected to the interior of the fixed shaft 4. The liquid outlet pipe 12 is connected to the interior of the fixed shaft 4. All the through holes 14 are evenly spaced, so that the lubricant can be evenly distributed on the fixed shaft 4.

[0032] Working principle: When the electric telescopic rod 16 closes the box door 2, the box door 2 will squeeze the buffer pad 7, causing the air inside it to enter the sealing cylinder 11 through the air outlet pipe 9. The sliding plug 13 moves under the pressure of the air, thereby squeezing the lubricating fluid. The lubricating fluid enters the interior of the fixed shaft 4 through the liquid outlet pipe 12, and flows into the space between the fixed shaft 4 and the mounting bracket 5 through the through hole 14. In this way, the fixed shaft 4 and the mounting bracket 5 can be lubricated every time the fire-fighting equipment is maintained, reducing the friction between them, so that the box door 2 can be opened quickly and smoothly, improving the safety and reliability of the device.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
