Description

Technical Field

[0001] This utility model relates to a fire extinguishing device, and more particularly to an integrated automatic tracking and positioning jet fire extinguishing device for electric vehicle sheds, belonging to the field of fire protection. Background Technology

[0002] The integrated automatic tracking and positioning jet fire extinguishing system for electric vehicle sheds is a water-based fire extinguishing device that extinguishes fires from a distance. Existing automatic tracking and positioning jet fire extinguishing systems are based on image-based fire detectors and image positioning technology. They monitor the fire source in real time, quickly locate the fire source through sensors and a control system, and automatically spray water directly onto the fire source, resulting in significant fire extinguishing effects, rapid control of the fire, reduced property damage, and continued monitoring after extinguishing the fire to prevent reignition.

[0003] The existing automatic tracking and positioning jet fire extinguishing system has the following drawbacks:

[0004] (1) Limited applicable locations: Automatic tracking and positioning jet fire extinguishing system is used in locations with fire category A and the fire extinguishing medium is water. It is not suitable when there are many items that explode or accelerate combustion when they come into contact with water, items that undergo violent chemical reactions or produce toxic and harmful substances when they come into contact with water, or liquids that will cause accidental splashing or boiling when water is sprayed.

[0005] (2) High water supply cost: Automatic tracking and positioning jet fire extinguishing system requires a complete water supply system, fire water tank, fire pump room, fire pump, water supply network and pump connection, pressure stabilization system, etc. The initial investment is large and the operation and maintenance cost is high.

[0014] The housing is a streamlined housing.

[0015] The fire extinguishing agent storage tank is made of corrosion-resistant material and is filled with a lithium battery-specific fire extinguishing agent. The gas cylinder is a high-pressure gas cylinder such as a steel cylinder or a carbon fiber cylinder.

[0016] The control device includes a signal processor and a field control box.

Detailed Implementation

[0029] The integrated automatic tracking and positioning jet fire extinguishing device for electric vehicle sheds will be further described below with reference to the accompanying drawings.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, this integrated automatic tracking and positioning jet fire extinguishing device for electric vehicle sheds is based on the original automatic tracking and positioning fire extinguishing device. The control system, fire extinguishing agent and power supply are integrated into the box structure 1. The box 1 is equipped with casters, which facilitates installation and relocation, occupies a small area and has a compact structure.

[0031] The integrated automatic tracking and positioning fire extinguishing device includes a housing 1 and an upper-mounted fully enclosed single-nozzle fire monitor 4. The housing 1 is divided into four sections by a partition. The middle section of the housing 1 houses an extinguishing agent storage tank 2 and a gas cylinder 3, connected by pipe I11. Pipe I11 is equipped with a solenoid valve I6 and a pressure regulator 5. The extinguishing agent storage tank 2 is also connected to a jet-type automatic tracking and positioning jet device located outside the housing 1 via pipe II12, which is equipped with a solenoid valve II7. The jet-type automatic tracking and positioning jet device, solenoid valve I6, and solenoid valve II7 are connected to a control device 10 on the upper part of the partition via power and control lines. The control device 10 is connected to a fixed fire-fighting power supply or powered by a UPS battery pack. The manual fire extinguishing device placement area on the inner side of the housing 1 houses a gas manual control valve 8, an extinguishing agent manual control valve 9, a hose, and a spray nozzle, meeting fire extinguishing requirements in the absence of power.

[0032] The upper part of the integrated automatic tracking and positioning fire extinguishing device housing 1 is a jet-type automatic tracking and positioning fire extinguishing device. Based on the original jet-type automatic tracking and positioning fire extinguishing device, the appearance and detection and activation equipment have been upgraded. The outer shell adopts a streamlined "Great White Shark" shell, meeting the dust and rain protection requirements of carports and even outdoor environments. While the original automatic tracking and positioning fire extinguishing devices mostly used infrared-ultraviolet composite positioning technology, with ultraviolet activation and infrared horizontal and vertical positioning, this new automatic tracking and positioning jet fire extinguishing device uses an image-type fire detector to monitor the protected area in real time. After detecting a fire, the control device 10 activates the image-type fire positioning system to achieve precise location of the fire source. After positioning, solenoid valves I6 and II7 are activated to spray extinguishing agent. After the fire is extinguished, the control device 10 automatically closes solenoid valves I6 and II7, stopping fire extinguishing. After confirming there is no fire point, the fully enclosed single-nozzle fire monitor 4 stands by for monitoring. If the fire reignites, it will restart, and the fire extinguishing cycle will continue. Compared to traditional spray-type automatic tracking and positioning fire extinguishing devices, this new type overcomes light interference, provides faster and more accurate positioning, and is more suitable for semi-enclosed structures such as carports or outdoor environments.

[0033] The integrated automatic tracking and positioning fire extinguishing device housing 1 contains a fire extinguishing agent storage tank 2 made of corrosion-resistant material, filled with lithium battery-specific fire extinguishing agent. The extinguishing medium is supplied to the automatic tracking and positioning jet device via pipeline II12. The gas cylinder 3 is preferably a high-pressure gas cylinder such as a steel cylinder or carbon fiber cylinder, which can be filled with compressed air, nitrogen, inert gas, etc., as needed. The outlet of the gas cylinder 3 is connected to a pressure reducer 5 and a solenoid valve I6. When the automatic tracking and positioning jet device sends an opening signal to solenoid valve I6, solenoid valve I6 opens, and high-pressure gas passes through pressure reducer 5 and pipeline I11 to charge the fire extinguishing agent storage tank 2. When the gas pressure reaches the device's working pressure, solenoid valve II7 opens to deliver the fire extinguishing agent to the fully enclosed single-nozzle fire monitor 4. The opening and closing of solenoid valves I6 and II7 are controlled by control device 10. The enclosed housing of the fully enclosed single-nozzle fire monitor 4 is connected to the pipeline channel above the housing via a flange. Power supply and control lines pass through the housing's inlet and outlet lines and connect to the nozzle 41 and the image acquisition device on the nozzle 41.

[0034] The control device 10 of the integrated automatic tracking and positioning fire extinguishing device is the "brain" of the system. It is responsible for receiving and analyzing fire detection signals, issuing control and alarm information, driving the fire extinguishing device to extinguish the fire at a specific location, and simultaneously performing corresponding display, recording, and signal transmission functions. It is also responsible for sending start and stop signals to solenoid valves I6 and II7. All information processing and process control components involved in the process from fire detection to the implementation of targeted fire extinguishing belong to the control device 10, which mainly includes a signal processor and a field control box. The signal processor and field control box are centrally located on the upper layer of the enclosure 1. The field control box is an important component of the fire extinguishing system; it is responsible for receiving signals from the fire detectors and determining whether to activate the fire extinguishing device based on preset logic. The design principle of the control box is based on safety and reliability considerations, ensuring that the fire extinguishing mechanism can be triggered quickly and accurately when a fire occurs. Its main functions include signal processing, logic judgment, and control of the fire extinguishing device.

[0035] For projects requiring centralized control, the integrated automatic tracking and positioning fire extinguishing device can be equipped with a video control host in the fire control room. The added high-definition camera can be used to observe the fire scene in real time, providing firefighters with an intuitive view of the scene to assist in decision-making. Alternatively, the host can control the automatic tracking and positioning fire extinguishing device to complete the processes of positioning, switching solenoid valves, and extinguishing the fire. The control device 10 also has a number of key functions, such as: self-test function, audible and visual alarm function, alarm information display, memory and printing function, real-time monitoring and recording of fire scene video, etc.

[0036] The integrated automatic tracking and positioning fire extinguishing device is powered by either 220V AC mains power or a battery pack. It uses AC mains power when available and the battery pack when AC mains power is unavailable. The battery pack can be installed in the lower compartment of the enclosure 1.

[0037] In addition, this utility model takes into account the situation of no power supply. The side of the box 1 is equipped with a gas manual control valve 8, a fire extinguishing agent manual control valve 9, a high-pressure hose and a spray gun. In the case of no power supply, the side door can be opened and the high-pressure hose and spray gun can be taken out to realize manual fire extinguishing.

[0038] In summary, the integrated automatic tracking and positioning fire extinguishing system has three functions: automatic control, manual control from the fire control room, and on-site manual control. Among these, manual control from the fire control room and on-site manual control have priority over automatic control.

[0039] The above describes specific embodiments of this utility model and the technical principles used. Any modifications or equivalent transformations based on the technical solution of this utility model should be included within the protection scope of this utility model.
