Description

Technical Field

[0001] This utility model relates to the field of fire protection, specifically to a fire box with a self-sprinkler mechanism. Background Technology

[0002] "Firefighting" means eliminating hidden dangers and preventing disasters (i.e., the general term for preventing and resolving man-made and natural or accidental disasters encountered by people in the process of life, work and study). Of course, in the early stages of people's understanding, firefighting meant extinguishing fires.

[0003] In existing technology, fire boxes are usually used to store fire-fighting equipment, such as fire hoses, fire axes, fire extinguishers, and fire hydrants, so that firefighters can quickly access and use them in a fire. However, in actual fire situations, when flames spread to the fire box, the high temperature of the flames can easily scorch the box, causing it to become hot and affecting the fire-fighting equipment inside. This can easily lead to damage to the equipment due to high temperatures, or make the equipment too hot to be easily accessed and used by firefighters. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a fire box with a self-spraying mechanism that can spray the cooling water stored in the box outward using a trigger-driven mechanism to achieve a self-spraying cooling effect, in light of the current state of the technology.

[0005] This utility model is achieved through the following technical solution: This utility model proposes a fire box with a self-sprinkling mechanism, including a box body, wherein a storage cavity and a main liquid cavity are respectively opened in the box body, wherein an upper guide cavity is connected above the main liquid cavity, a spray plate is fixedly installed at one end of the upper guide cavity in the box body, and a driving mechanism is also installed in the main liquid cavity;

[0006] The driving mechanism includes a pressure plate and a spring. The spring is fixedly installed at the bottom of the main liquid chamber, and the pressure plate is fixedly connected to the top of the spring. The pressure plate is sealed and slidably connected within the main liquid chamber. Under the action of the spring, the pressure plate compresses the water in the main liquid chamber to flow through the upper guide cavity and is sprayed outward through the spray plate.

[0007] Furthermore, the driving mechanism also includes a heat-fused component, which is detachably connected to both ends of the pressure plate and passes through the housing and is fixedly connected.

[0008] Furthermore, a sealing valve cover for replenishing water into the main liquid chamber is installed at the upper end of the housing via a slot.

[0009] Furthermore, a secondary liquid chamber is provided on one side of the main liquid chamber inside the box, and the lower part of the secondary liquid chamber is connected to the main liquid chamber and the lower guide chamber respectively.

[0010] Furthermore, a sealing valve cover and a vent valve cover are installed on the upper end of the housing via a slot. The sealing valve cover is used to control the opening and closing of the main liquid chamber, and the vent valve cover is used to control the opening and closing of the auxiliary liquid chamber.

[0011] Furthermore, a door is rotatably connected to the surface of the storage cavity of the box body.

[0012] Furthermore, a fire hose, a fire axe, and a fire hydrant are respectively installed inside the storage cavity.

[0013] Compared with the prior art, this utility model has the following advantages:

[0014] This invention features a main liquid chamber inside the enclosure for storing cooling water. A pressure plate, under the action of a spring, compresses the cooling water, which then flows through an upper guide chamber and is sprayed onto the outer surface of the enclosure via a spray plate. This allows the water to cool the enclosure door and enclosure, while also extinguishing flames below or near the enclosure to prevent the flames from heating the enclosure and causing high temperatures. Furthermore, it avoids damaging the fire-fighting equipment stored inside the enclosure, facilitating access and use by firefighters. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] like Figure 1 , Figure 3 and Figure 4 As shown, a fire box with a self-sprinkling mechanism in this embodiment includes a box body 1. The box body 1 has a storage cavity 101 and a main liquid cavity 102 respectively. The upper part of the main liquid cavity 102 is connected to an upper guide cavity 104. A spray plate 105 is fixedly installed on one end of the upper guide cavity 104 on the box body 1. A drive mechanism 3 is also installed in the main liquid cavity 102.

[0028] The drive mechanism 3 includes a pressure plate 301 and a spring 302. The spring 302 is fixedly installed at the bottom of the main liquid chamber 102, and the pressure plate 301 is fixedly connected to the top of the spring 302. The pressure plate 301 is sealed and slidably connected inside the main liquid chamber 102. Under the action of the spring 302, the pressure plate 301 compresses the water in the main liquid chamber 102 to flow through the upper guide chamber 104 and spray it outward through the spray plate 105.

[0029] This application provides a fire box with a self-spraying mechanism that can spray cooling water stored inside the fire box 1 outward using a trigger-driven mechanism to achieve a self-spraying cooling effect. This solves the problem in the prior art where fire boxes easily generate high temperatures due to fire exposure, which also affects the fire equipment inside the box, leading to damage or making the equipment difficult for firefighters to handle. The overall approach to solving these problems in this embodiment is to create a self-spraying mechanism inside the box 1... The main liquid chamber 102 stores the cooling water, and the pressure plate 301, under the action of the spring 302, squeezes the cooling water, allowing it to flow through the upper guide chamber 104 and spray onto the outer surface of the box 1 through the spray plate 105. This allows the water to cool the box door 2 and the box 1, and also extinguishes flames below or near the box 1, preventing the flames from baking the box 1 and generating high temperatures. It also prevents the fire-fighting equipment stored inside the box 1 from being affected by high temperatures, making it easier for firefighters to access and use the equipment.

[0030] The main innovation of this invention is that it uses a trigger-type pressure drive mechanism to drive the pre-stored cooling water in the box 1 to spray onto the surface of the box 1 and extinguish the surrounding flames to achieve a cooling effect. Specifically, the trigger mechanism can utilize the material properties of heat deformation to meet its triggering conditions, or it can use electronic devices such as temperature sensors as the trigger mechanism. However, due to the power supply form of electronic devices, their stability is not as good as the material properties of heat deformation itself.

[0031] As one implementation method, such as Figure 1 , Figure 3 and Figure 5 As shown, the drive mechanism 3 also includes a heat-fusion component 303, which is detachably connected to both ends of the pressure plate 301. The heat-fusion component 303 passes through the box 1 and is fixedly connected. In this embodiment, when the flame bakes the box 1, the surface of the box 1 will undergo a temperature change, and the heat-fusion component 303 will melt when subjected to high temperature. Therefore, the limiting effect on the pressure plate 301 will be released, and the spring 302 will release its contracted stored energy, so that the pressure plate 301 can move upward under the action of the spring 302 and squeeze the water in the main liquid chamber 102, so that the water can flow into the upper guide chamber 104 and be sprayed onto the outer surface of the box 1 and part of the box door 2 through the spray plate 105, thereby achieving a cooling effect and extinguishing the surrounding flammable materials.

[0032] As one implementation method, such as Figures 3-5As shown, a secondary liquid chamber 103 is also provided on one side of the main liquid chamber 102 inside the box 1. The lower part of the secondary liquid chamber 103 is connected to the main liquid chamber 102 and the lower guide chamber 106 respectively. The secondary liquid chamber 103 can be used to inject an appropriate amount of spare cooling water. The spare cooling water will fill the secondary liquid chamber 103 and the lower guide chamber 106. When the pressure plate 301 moves upward and squeezes the water in the main liquid chamber 102 to be discharged through the spray plate 105, the lower end of the pressure plate 301 will generate a negative pressure effect. The negative pressure effect will be used to draw the spare cooling water in the secondary liquid chamber 103 into the main liquid chamber 102 to fill the area below the pressure plate 301, so as to be retained in the box 1 for use as cooling water in the future, thereby improving the high temperature resistance of the box 1.

[0033] As one implementation method, such as Figures 1-3 As shown, the upper end of the housing 1 is equipped with a sealing valve cover 401 for replenishing water into the main liquid chamber 102 and a vent valve cover 402 for replenishing water into the secondary liquid chamber 102 via a slot. The sealing valve cover 401 is used to control the opening and closing of the main liquid chamber 102, and the vent valve cover 402 is used to control the opening and closing of the secondary liquid chamber 103. The sealing valve cover 401 acts as a seal to ensure that the water in the main liquid chamber 102 can only flow through the upper guide chamber 104 to avoid leakage. The vent valve cover 402 can maintain the communication between the secondary liquid chamber 103 and the outside air, so that when the pressure plate 301 moves, the water in the secondary liquid chamber 103 can be smoothly drawn into the lower part of the main liquid chamber 102.

[0034] As one implementation method, such as Figures 1-3 As shown, a door 2 is rotatably connected to the surface of the storage cavity 101 of the housing 1; a fire water pipe 501, a fire axe 502 and a fire hydrant 503 are respectively installed in the storage cavity 101; the door 2 can provide protection for the various fire-fighting equipment stored in the storage cavity 101.
