Description

Technical Field

[0001] The present application relates to security equipment, and in particular to a main control box with explosion-proof and fire-extinguishing functions. Background Art

[0002] In modern security systems, especially those designed for fire extinguishing, the function of the main control box is crucial. Its main responsibility is to control and monitor the operation of the entire security facility. In emergency situations such as fires, especially in the event of power outages, the main control box must be able to ensure the continued operation of the system to perform fire extinguishing operations. To achieve this goal, the main control box is usually equipped with energy storage battery packs that can provide the necessary power support when the external power supply is interrupted.

[0003] However, with the rapid development of technology, the current design of the main control box has shown several key defects, which urgently need to be improved by introducing advanced technology.

[0004] Specifically, the existing main control box is relatively simple in design and structure, and does not fully consider the fire risk that may be triggered by the internal battery pack when it encounters high temperature or other abnormal conditions. If the battery pack catches fire, not only will the main control box itself be severely damaged, but it may also cause the failure of the entire security system and even cause a wider fire disaster.

[0005] In addition, most existing main control boxes lack effective active protection measures, such as a built-in automatic fire extinguishing system. This means that once a fire occurs inside the main control box, it cannot extinguish the flames by itself. This design flaw not only makes the main control box powerless when a fire occurs, but also increases the risk of fire spreading, posing a threat to the safety of the entire building.

[0006] In view of these problems, it becomes particularly important to develop a new main control box with explosion-proof and automatic fire extinguishing functions. Utility Model Content

[0007] The purpose of the present application is to overcome at least one of the shortcomings of the prior art and to provide a main control box with explosion-proof and fire-extinguishing function. The main control box integrates an explosion-proof and fire-extinguishing structure in the main control box, so that when an abnormal fire occurs in the battery pack, the fire extinguishing mechanism can be immediately activated to prevent the fire from spreading, thereby greatly improving the safety of the entire system.

[0008] To achieve the above purpose, the present application discloses a main control box with explosion-proof and fire-extinguishing functions, including a box body with an installation compartment, an inner liner located in the installation compartment,

[0009] Wherein, the box body has a box bottom and a box cover, and the box cover cooperates with the box bottom opening to form an installation compartment;

[0010] The installation bin is provided with a ventilation hole group on one side of the bottom of the box as the external ventilation surface, and correspondingly, ventilation holes are provided on the opposite surface of the inner lining bladder to the external ventilation surface of the bottom of the box as the internal ventilation surface;

[0011] The inner lining bladder is in a U-shaped-like form. The inner lining bladder is located inside the installation bin and is spaced from the installation bin at the side and bottom. The above-mentioned spaces form a heat insulation layer and a heat insulation layer relative to the box body; the inner lining bladder is hermetically matched with the box cover to form a working chamber;

[0012] At least one cooling and fire extinguishing pipe is inserted into the working chamber from the other side of the box body relative to the external ventilation surface. The cooling and fire extinguishing pipe is connected to an air inlet pipe and a water inlet pipe through an electric control three-way valve, and is controlled by the electric control three-way valve to selectively connect to the air inlet pipe / water inlet pipe;

[0013] At least one flame retardant ventilation plate is provided in the working chamber of the inner lining bladder. The flame retardant ventilation plate group divides the internal space in the direction of the cooling and fire extinguishing pipe and the internal ventilation surface in the working chamber. Among them, the flame retardant ventilation plate group and the internal ventilation surface cooperate to form a battery installation area, and other areas outside the battery installation area in the working chamber are used as the main control board installation area.

[0014] A flow equalizing plate is installed on the inner lining bladder near the cooling and fire extinguishing pipe. A number of holes are evenly provided on the flow equalizing plate to achieve the purpose of equalizing the flow of liquid / gas.

[0015] Compared with the prior art, the present application has at least the following beneficial effects:

[0016] 1. The main control box is provided with a heat insulation layer, which effectively isolates the influence of external high temperature on the internal battery pack and other key components, ensuring the safe operation of the system in a high temperature environment.

[0017] 2. The cooling and fire extinguishing pipe can introduce cooling air flow under normal conditions to help the internal components dissipate heat. When a fire or other abnormal conditions are detected, the cooling and fire extinguishing pipe can be quickly switched to introduce fire extinguishing liquid or gas to achieve efficient fire extinguishing and prevent the spread of fire.

[0018] 3. The design of the ventilation hole group and the flame retardant ventilation plate on the box body and the inner lining bladder enables the system to maintain a good ventilation state during normal operation, further improving the heat dissipation efficiency, and effectively isolating the fire source in case of emergency.

[0019] 4. The built-in electric control three-way valve and flow equalizing plate design ensure that the fire extinguishing medium can be evenly distributed when starting, reducing the fire extinguishing blind area, improving the fire extinguishing efficiency, reducing manual intervention, and improving the automation level and emergency response ability of the system.

[0020] The above-listed beneficial effects are not exhaustive of all advantages. Other potential beneficial effects and detailed technical implementations will be further disclosed in the examples or other description parts of this application. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Figures 1 to 4 Disclosed is an exemplary structure for achieving the technical purpose of the present application, specifically a main control box with explosion-proof and fire extinguishing functions.

[0031] The main control box is composed of a sturdy box body 1 and a lining bladder 2 located inside the box body 1.

[0032] The structure of the box body 1 includes a box bottom 101 and a box cover 102. The box cover 102 is closely fitted with the opening of the box bottom 102 to form a sealed installation chamber 103 to ensure the stability and relative tightness of the internal environment.

[0033] To ensure good air circulation and heat dissipation performance, a set of ventilation hole groups 104 are provided on one side surface of the box bottom 101. This surface serves as an external ventilation surface 105 through the ventilation hole groups 104, enabling air to freely enter and exit to avoid excessive internal temperature. Suitable for the above structure, ventilation holes are provided on the opposite surface of the lining bladder 2 and the external ventilation surface 105 in the box bottom 101 as an internal ventilation surface 202, and these ventilation holes ensure the circulation of internal and external air and further improve the heat dissipation efficiency.

[0034] The lining bladder 2 is in a U-shaped-like form, installed in the installation chamber 103, and is spaced from the side and bottom surfaces of the installation chamber 103 to form a heat insulation layer 201. This heat insulation layer 201 not only helps with heat dissipation but also plays a role in heat insulation, preventing the external high temperature from affecting the normal operation of the internal components.

[0035] The lining bladder 2 is hermetically fitted with the box cover 102 to form a working chamber 201, which provides a stable and safe internal environment to ensure the operation of the internal components under safe conditions.

[0036] In this embodiment, the main control box has a cooling and fire extinguishing function. The need for this function requires at least one cooling and fire extinguishing pipe 3, and the cooling and fire extinguishing pipe 3 is inserted into and enters the working chamber 201 from the other side of the box body 1 relative to the external ventilation surface 105. The cooling and fire extinguishing pipe 3 is connected to an air inlet pipe 204 and a water inlet pipe 205 through an electric control three-way valve 203, and the electric control three-way valve 203 can control the connection of the cooling and fire extinguishing pipe 3 with the air inlet pipe 204 or the water inlet pipe 205 as needed, thereby achieving a rapid switching of the medium.

[0037] Under normal conditions, cooling airflow is introduced into the cooling fire extinguishing pipe 3 to help dissipate heat; when an abnormal situation is detected, the system can quickly switch to the fire extinguishing mode, introduce liquid or gas for fire extinguishing, and perform efficient fire extinguishing operations.

[0038] At least one flame-blocking ventilation plate 206 is also provided in the working chamber 201 of the inner liner 2. The flame-blocking ventilation plate 206 divides the internal space in the working chamber 201 to form two independent areas: a battery installation area 207 and a main control board installation area 208.

[0039] It is understandable that the design of the flame-blocking ventilation plate 206 can not only effectively isolate the fire source, but also prevent the fire from spreading to other parts of the entire main control box when a fire occurs. The liner 2 is installed with a flow equalizing plate 207 on the side close to the cooling fire extinguishing pipe 3. The flow equalizing plate 207 is evenly provided with a number of holes for achieving uniform distribution of liquid or gas, ensuring that the cooling airflow or fire extinguishing medium can evenly cover the entire working chamber 201.

[0040] The entire main control box is designed to improve the safety and reliability of the system. By integrating explosion-proof and fire-extinguishing structures in the main control box, the fire-extinguishing mechanism can be immediately activated when an abnormal fire occurs in the battery pack to prevent the fire from spreading and ensure the safety of the main control box and the entire security system. At the same time, through reasonable structural design and material selection, the main control box can still maintain a good operating state under high temperature or other abnormal conditions.

[0041] In terms of material selection, the main control box body 1 and the inner lining 2 are made of high-strength, high-temperature resistant metal materials to ensure its structural stability and safety in fire or high-temperature environments. The cooling fire extinguishing pipe 3 and the electric three-way valve 203 are made of corrosion-resistant and non-aging materials to ensure their long-term reliability and stability. The flame-blocking ventilation plate 206 and the flow equalizing plate 207 are made of refractory materials to ensure that they will not fail due to high temperatures when a fire occurs.

[0042] The working principle of the main control box is based on the synergy of its internal components. When the system is operating normally, the main control box provides power support through the energy storage battery pack to ensure the continuous monitoring and operation of the entire security system. When the battery pack or internal temperature is detected to be abnormally high, the cooling and fire extinguishing pipe 3 in the main control box is immediately activated, and the appropriate fire extinguishing medium (gas or liquid) is selected through the electric three-way valve 203, and evenly distributed in the working chamber 201 through the flow plate 207 to cool and extinguish the battery pack or other electrical components. The flame-blocking ventilation 206 board effectively isolates the fire source and prevents the fire from spreading to the main control board installation area 208, thereby protecting the core control components of the entire system.

[0043] Although the exemplary embodiments of the present disclosure have been described, it should be understood by those skilled in the art that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure in essence. Therefore, all changes and modifications are included in the scope of protection of the present disclosure as defined by the claims. The present disclosure is defined by the appended claims, and the equivalents of these claims are also included.
