Description

Technical Field

[0001] This utility model relates to the field of garage fire protection technology, specifically to an intelligent fire extinguishing system for garages. Background Technology

[0002] With the increasing modernization of cities, numerous parking garages have sprung up in various areas, including commercial districts, municipal government offices, office buildings, and residential communities. These garages play a vital role in alleviating urban parking difficulties and traffic congestion. However, the safety of these garages has become a major concern, especially given the significant safety hazards posed by fires within them. Sometimes, fires are so large that they are difficult to extinguish, requiring fire trucks to arrive. By the time fire trucks arrive, the fire has already caused substantial damage.

[0003] With the increasing popularity of new energy vehicles, the prevention and control of fires in parking garages has become even more challenging. New energy vehicle fires are characterized by their extreme suddenness and rapid combustion. When lithium batteries experience thermal runaway, their internal temperature can rapidly rise to 600-1000℃ within a short period, releasing large amounts of flammable gases (such as hydrogen, methane, and acetylene) and toxic gases (such as hydrogen fluoride and hydrogen cyanide). These characteristics make traditional fire extinguishing methods (such as carbon dioxide or dry powder extinguishers) ineffective. The fire can also spread rapidly to surrounding vehicles. Once ignited, the fire can quickly spread to nearby vehicles, leading to greater losses. Traditional fire suppression systems are often ineffective in controlling fires involving new energy vehicles due to their low extinguishing efficiency.

[0004] Currently, most parking garages use traditional fire protection systems, mainly including fire alarm devices, sprinkler systems, and fire extinguishers. While these systems play a crucial role in fire prevention, they still have many shortcomings in responding to fires in modern parking garages. For example, the batteries of new energy vehicles are usually installed at the bottom of the vehicle, in a concealed location, making it difficult for fire extinguishing agents to directly reach the battery interior, resulting in low extinguishing efficiency. Traditional sprinkler systems only place nozzles above the fire area, spraying the extinguishing agent from top to bottom, which is ineffective in extinguishing fires under the vehicle. Furthermore, traditional systems lack intelligent zoning control functions; once a fire occurs, the extinguishing agent may be sprayed into unaffected areas, causing resource waste and unnecessary equipment damage.

[0005] There are many causes of fires, including arson and electrical fires, which are all important reasons for fires. Although various monitoring methods are being updated and upgraded, fires still cannot be prevented. Therefore, in addition to fire prevention, it is more important to introduce new fire monitoring and extinguishing equipment and corresponding systems to solve the problem of "control" in the two levels of fire prevention and control. The key to solving this problem is how to quickly extinguish small fires and prevent them from escalating into disasters.

[0006] To address the shortcomings of existing technologies, this utility model proposes an intelligent fire extinguishing system for garages. Utility Model Content

[0007] To address the problems of rapid fire spread, difficulty in extinguishing, and the rapid spread of flames to surrounding vehicles after a car fire in a garage, this patent provides a solution: an intelligent fire suppression system for garages. The system comprises a fire suppression control cabinet, fire piping, a high-precision infrared fire detector, temperature-sensing cables, a fireproof cloth enclosure, solenoid valves, concealed nozzles, and PP plastic partitions. The fire suppression control cabinet is fixed to the garage floor and has an external cabinet structure. Internally, it contains a fire extinguishing agent storage tank. A fire inlet pipe is connected to the lower left side of the storage tank, allowing for external piping to refill the tank with fire extinguishing agent. A fire outlet is located on the lower right side of the control cabinet, connected to a fire... The main fire protection pipeline extends to near the ground level, where a PP plastic partition is laid. The main fire protection pipeline connects to a fire manifold installed on the PP plastic partition. Each branch of the fire manifold is connected to a solenoid valve, which is connected to a tee for each zone. The tee is connected to both the vertical and underground fire branch pipelines. A top nozzle is connected to the end of the vertical fire branch pipeline, which releases the extinguishing agent from top to bottom. The underground fire branch pipeline is connected to two underground concealed nozzles, which release the extinguishing agent from bottom to top, thus protecting against fires on the roof and under the vehicle.

[0008] The fire suppression control cabinet contains an integrated fire suppression controller. A high-precision infrared fire detector mounted on the garage ceiling and a temperature-sensing cable laid on a PP plastic partition are connected to the integrated fire suppression controller inside the cabinet. The high-precision infrared fire detector and temperature-sensing cable detect fire signals and transmit them to the integrated fire suppression controller as electrical signals. The integrated fire suppression controller is connected to the control terminal of the fireproof cloth box, which can transmit alarm signals to the fireproof cloth box. Upon receiving a fire signal, the fireproof cloth box will control the laying of the fireproof cloth to prevent the spread of fire at the first moment. The integrated fire suppression controller is connected to the fire pump set and the corresponding area's solenoid valves. Upon receiving a fire signal, the integrated fire suppression controller will delay the activation of the fire pump set and the corresponding area's solenoid valves. After the fireproof cloth is laid, the fire pump set and solenoid valves will open to release a special fire extinguishing agent.

[0009] Preferably, the system adopts a zoned design, dividing the 20 parking spaces into 20 fire control zones. Each zone is equipped with a solenoid valve, and each protected zone can independently carry out fire protection.

[0010] Preferably, each fire control zone is equipped with an independent fire detector module, fire isolation device and fire extinguishing nozzle system to ensure rapid response and precise control in the event of a fire;

[0011] Preferably, the fire extinguishing control cabinet integrates a fire extinguishing agent storage tank to store the special fire extinguishing agent. It contains a level gauge, which can be used to replenish the special fire extinguishing agent in a timely manner by observing the level indicator bar.

[0012] Preferably, the fire extinguishing control cabinet integrates a fire controller that can receive electrical signals from high-precision infrared fire detectors and temperature sensing cables, and process them in stages to transmit them to the fireproof cloth box, fire pump group, and solenoid valve.

[0013] Preferably, each fire control zone is equipped with a high-precision infrared fire detector at the top and a heat-sensing cable at the bottom for real-time three-dimensional fire monitoring from top to bottom; the fire information is transmitted to the integrated fire extinguishing controller in the fire extinguishing control cabinet in the form of electrical signals to ensure that the system can respond quickly to the fire.

[0014] Preferably, each parking space is equipped with fireproof sheet boxes in all four directions (front, back, left, and right). Upon receiving a fire signal, the fireproof sheet boxes can quickly lay fireproof sheeting to form a physical barrier, preventing the fire from spreading to adjacent parking spaces. The fireproof sheeting is laid before the fire pump unit starts, ensuring isolation is completed before the extinguishing agent is released.

[0015] Preferably, each fire protection control area is equipped with a top sprinkler and two underground invisible sprinklers. The top sprinkler is used to spray the fire extinguishing agent from top to bottom, while the underground invisible sprinkler is used to spray the fire extinguishing agent from bottom to top, which can quickly extinguish the fire at the bottom of the vehicle and improve the fire extinguishing efficiency.

[0016] Preferably, the ground of each fire protection control area is paved with PP plastic partitions, which is convenient for laying fire-fighting pipelines, sprinklers and temperature-sensing cables, and changes the installation method of traditional underground invisible sprinklers that require pre-burying fire-fighting pipelines underground.

[0017] Preferably, a solenoid valve is connected to each branch of the fire-fighting manifold in each fire protection control area to control the spraying of the fire extinguishing agent. After receiving the fire signal, the integrated fire extinguishing controller can accurately control the opening of the solenoid valve in the corresponding area to achieve zoned fire extinguishing.

[0018] Preferably, the integrated fire extinguishing control cabinet system has two control modes: manual and automatic, which can be flexibly switched according to the actual situation, enhancing the reliability and flexibility of the system.

[0019] The problems solved by the present utility model compared with the prior art are as follows:

[0020] (1) This fire extinguishing system is equipped with a fireproof cloth box at the same time. The fireproof cloth boxes are arranged in the four directions of front, back, left and right of each parking space partition. After receiving the laying signal sent by the integrated fire extinguishing controller, the control switch on the fireproof cloth box starts, and the fireproof cloth can quickly fall and spread out to isolate and protect the area where the fire occurs, effectively reducing the spread of the fire. At the same time, by controlling the system, the starting time of the fireproof cloth laying is earlier than the starting time of the fire pump group. After the fireproof cloth is laid, the fire extinguishing agent is sprayed to avoid the influence of the fire extinguishing agent on the vehicles outside the fire protection area.

[0021] (2) This fire extinguishing system improves the layout of traditional fire-fighting sprinklers. Most traditional fire-fighting sprinklers are only arranged directly above the fire protection area to spray the fire extinguishing agent from top to bottom. Considering the actual situation of vehicle fires, some fires actually occur at the bottom of the vehicle. The top-down spraying method of traditional fire-fighting sprinklers cannot quickly and effectively control the fire at the bottom of the vehicle. Considering the timeliness of fire extinguishing control, the present utility model adds two invisible sprinklers on the garage floor. When a fire occurs at the bottom of the vehicle, spraying the fire extinguishing agent from bottom to top can directly reach the ignition point for efficient fire extinguishing, and cooperating with the top sprinklers greatly improves the fire extinguishing efficiency of vehicle fires.

[0022] (3) This fire extinguishing system uses high-precision infrared fire detectors and heat-sensing cables. Each of the 20 parking spaces is equipped with one set. When a fire occurs, the high-precision infrared fire detectors can respond quickly from the top, and the heat-sensing cables can respond quickly from the bottom. The fire detection is carried out in a three-dimensional manner from top to bottom, which is faster than the traditional technology. The battery pack of new energy vehicles is located at the bottom of the vehicle. Traditional fire detection is carried out from top to bottom, which cannot respond in time to the fire of the battery pack of new energy vehicles. The method of laying heat-sensing cables on the ground effectively improves the timeliness of early fire detection of the battery pack of new energy vehicles.

[0023] (4) This fire extinguishing system is the first to introduce PP plastic partitions into the garage fire extinguishing system. Traditional fire extinguishing schemes require the corresponding pipes to be pre-buried in the ground when laying pipes, which increases the difficulty and cost of installation and is not convenient for later maintenance and repair. Laying PP plastic partitions on the garage floor allows the pipes and nozzles to be directly installed on the PP plastic partitions, ensuring the fire extinguishing function while improving the feasibility of the entire fire extinguishing system deployment. At the same time, the use of PP plastic partitions is waterproof and moisture-proof, avoiding long-term contact between the vehicle chassis, tires and other parts and the humid environment, reducing rust and aging, and extending the service life of the vehicle.

[0034] The present invention will be further described below with reference to the accompanying drawings and specific examples in the new embodiments of the present invention.

[0035] See attached document Figure 1 A smart fire suppression system for a parking garage includes a fire suppression control cabinet 1, with a fire outlet on the lower right side connected to a fire manifold 3 via a bend 2; (as shown in the figure, there are 20 identical parking space protection zones; this description only details one of these zones, while the other zones are identical to the example described herein). PP plastic partitions 14 are laid on the garage floor, and the fire manifold 3 is laid on top of these partitions. The fire manifold 3 has 20 branch outlets, each connected to a solenoid valve 4. The other end of each solenoid valve is connected to a zone tee 5, serving as the extinguishing agent inlet for a single fire control zone. The zone tee 5 is horizontally connected to an underground fire branch pipeline 6. The other end of the underground pipe 6 is connected to a tee, which connects vertically upward to underground concealed sprinkler head 7 and horizontally to underground pipe 6 of the fire branch. The end of the tee is connected to underground concealed sprinkler head 8 via an elbow. The zoning tee 5 connects vertically to vertical pipe 9 of the fire branch. The end of the pipe is connected to top sprinkler head 10 via an elbow. Fireproof cloth boxes 11 are fixed above the front, back, left, and right sides of the garage. High-precision infrared fire detectors 12 are fixed on the fireproof cloth boxes 11 with brackets. Temperature sensing cables 13 are laid on the PP plastic partition. Solenoid valves 4, zoning tee 5, underground pipe 6 of the fire branch, underground concealed sprinkler head 7, and underground concealed sprinkler head 8 are all arranged on the PP plastic partition.

[0036] Refer to the attached document for the internal structure of the fire extinguishing control cabinet. Figure 3 The fire extinguishing control cabinet 1.1 is fixed to the garage floor and houses the fire extinguishing agent storage tank 1.2. The fire extinguishing agent storage tank 1.2 is equipped with a level gauge, and the remaining amount of the special fire extinguishing agent in the storage tank 1.2 can be observed through the level indicator bar 1.3, allowing for timely replenishment. The fire extinguishing control cabinet 1 integrates a controller, which can be controlled via buttons including: a power indicator light 1.4, an emergency start button 1.5, a manual fireproof cloth laying button 1.6, an emergency stop button 1.7, a fire water inlet button 1.8, and a manual / automatic switch button 1.9. It can switch between manual and automatic modes and provide both manual and automatic control of the fire extinguishing system according to the actual situation.

[0037] Specific example 1: Automatic fire suppression mode:

[0038] When the garage fire suppression system is in automatic mode, if a fire occurs in a parking space protection zone within the garage, the high-precision infrared fire detector alarm 12 or the temperature sensing cable 13 will immediately acquire the fire information and transmit it to the fire suppression control cabinet 1 via electrical signals. The integrated controller in the fire suppression control cabinet 1 will analyze and process the fire signal, locate the parking space where the fire occurred, and transmit the fire information to the fireproof cloth box 11 via electrical signals. Upon receiving the fire signal, the fireproof cloth laying mechanism in the fireproof cloth box 11 will open to lay the fireproof cloth. Simultaneously, the integrated controller in the fire suppression control cabinet 1 will transmit electrical signals to the fire pump group 1.11 and the corresponding solenoid valve 4 in the parking space protection zone after 5 seconds, synchronously opening the fire pump group 1.11 and the corresponding solenoid valve 4. The three nozzles in the corresponding parking space protection zone will then begin to release extinguishing agent, thereby controlling the fire.

[0039] Specific Example 2: Manual Fire Extinguishing Mode

[0040] When a fire occurs in a parking space protection zone within the garage, the fire does not trigger a response from the high-precision infrared fire detector 12 or the temperature sensing cable 13, and the system does not respond automatically. If the fire is discovered by relevant personnel, the manual / automatic switch 1.9 can be adjusted to manual mode, and the emergency start button 1.5 can be pressed. This will control the fireproof cloth laying mechanism in the fireproof cloth box 11 to open and lay the fireproof cloth. Simultaneously, the integrated controller in the fire extinguishing control cabinet 1 will transmit an electrical signal to the fire pump group 1.11 and the corresponding solenoid valve 4 in the parking space protection zone after 5 seconds, synchronously opening the fire pump group and the corresponding solenoid valve. The three nozzles in the corresponding parking space protection zone will then begin discharging extinguishing agent, thus controlling the fire.

[0041] Specific Example 3: Handling False Alarms

[0042] When the garage fire suppression system is in automatic fire suppression mode, the high-precision infrared fire detector 12 or the heat sensing cable 13 detects fire information and gives corresponding feedback. However, if there is no fire in the actual parking space protection zone, but a false alarm is caused by external factors, the manual / automatic switch button can be adjusted to the manual position 1.9, and the emergency stop button 1.7 can be pressed to stop the garage fire suppression system from responding and stop subsequent actions.
