Description

Technical Field

[0001] The present invention relates to the technical field of garage safety, and in particular, the present invention relates to a garage fire prevention method. Background Art

[0002] Currently, with the development of technology, the use of vehicles is increasing. The increase in the number of vehicles has also led to a large garage area, a complex environment, and a messy pipeline system for space equipment in traditional underground garages. There is basically no consideration of the combination of fire protection characteristics and functions. The systems of new-style duplex garages, LOFT garages, etc. are simpler in setting, and because of their high utilization rate, energy conservation and environmental protection, and good user experience, they are widely welcomed by the market.

[0003] However, there are more vehicles parked in such garages. There is a risk of spontaneous combustion of new energy electric vehicles during the charging process. There are few targeted fire protection measures and equipment for vehicle fires in the parking lot environment. Moreover, traditional fire extinguishers, sprinkler facilities, and even large water guns are difficult to quickly stop the combustion of new energy vehicles. Once a fire breaks out, it often leads to rapid spread and "fire spreading to adjacent vehicles", causing greater property losses.

[0004] In order to carry out fire prevention and safety settings for the garage, the current optional fire prevention setting is to isolate multiple parking spaces so that when one vehicle catches fire, it will not spread, ensuring the safety of other vehicles. For example, Chinese Patent Invention CN118512733A discloses a fire prevention isolation device for parking spaces, which is applied to a designated parking area. There are multiple parking spaces in the designated parking area, and the parking area is a closed or semi-closed space, and the closed or semi-closed space includes the support area of the designated parking spaces in the designated parking area; the fire prevention isolation device is arranged relative to the parking line of the parking space, and the fire prevention isolation device is used to form a fire prevention isolation wall along the extension direction of the corresponding parking line and vertically, horizontally or obliquely to isolate the vehicles in the corresponding parking space. This application also provides a garage fire prevention isolation system. This application adopts the isolation method. When a fire is detected, the fireproof cloth in the isolation device automatically unfolds, and a fire prevention isolation space for isolating the vehicle on fire will be formed at the parking space, effectively avoiding the fire vehicle from affecting surrounding vehicles or flammable items and expanding the loss.

[0005] However, the above fire isolation device still has the following disadvantages: A large number of isolation devices are required in a garage to isolate multiple parking spaces one by one, resulting in high installation costs; moreover, the presence of the isolation wall poses a risk of scratching when the vehicle enters the garage. Some vehicles are parked irregularly, being too far forward or backward, which will cause them to go beyond the blocking range of the isolation wall, resulting in insufficient isolation safety. Finally, although the burning vehicle is effectively isolated, it will still burn violently. Not only will the vehicle still be damaged by the fire, but a large amount of toxic and harmful high-temperature gases generated by the vehicle fire will still pervade the entire garage space, causing other losses.

[0006] Therefore, to solve the above problems, it is necessary for us to design a garage fire prevention method. Summary of the Invention

[0007] The purpose of the present invention is to provide a garage fire prevention method. When a vehicle catches fire, the driving platform is displaced above the burning vehicle, and a fireproof cloth is lowered to cover the burning vehicle. Only one fireproof platform needs to be set in one garage area, with low installation costs and no impact on vehicle entry and exit from the parking space. By using two descents and two displacements, the burning vehicle at each position can be quickly and accurately covered. Through two fire extinguishing operations, the burning vehicle under the cover will stop burning due to lack of oxygen, and the toxic and harmful gases are effectively isolated within the fireproof cloth, with high safety.

[0008] To achieve the above object, the present invention is realized by adopting the following technical solutions: A garage fire prevention method is applicable to a garage fire prevention structure.

S3: Second descent and first fire extinguishing; the lifting frame is driven to descend to the ground at a second speed. At this time, the fireproof cloth covers the burning vehicle, and the fire extinguishing member is started to conduct the first fire extinguishing of the burning vehicle. S4: Second fire extinguishing; after a preset time, it is judged whether the temperature inside the fireproof cloth is higher than a preset temperature value. If so, the fire extinguishing member is started to conduct the second fire extinguishing of the burning vehicle; otherwise, no operation is performed.

[0022] Example: As Figures 1 to 4 shown, Figure 1 is a schematic flow chart of a method for preventing fire in a garage according to the present invention, which is only one embodiment of the present invention. A method for preventing fire in a garage is applicable to a garage fire prevention structure. The structure includes a slide rail and a platform disposed on the slide rail. The platform includes a first-level platform connected to the slide rail and a second-level platform connected to the first-level platform. A slideway for facilitating the sliding of the second-level platform is provided on the first-level platform. A lifting frame is connected to the lower side of the second-level platform through a fireproof cloth, and a fire extinguishing member is provided on the lower side of the second-level platform; Specifically, the garage fire prevention structure includes a slide rail 3 and a platform 1 disposed on the slide rail 3. A lifting frame 2 is connected to the lower side of the platform 1 through a pull rope 22. A fireproof cloth 21 is connected between the platform 1 and the lifting frame 2. A first motor for driving the platform 1 to displace along the slide rail 3 is provided on the platform 1. A third motor for winding and unwinding the pull rope 22 is provided on the platform 1; The platform 1 includes a first-level platform 11 generally disposed above the slide rail 3 and a second-level platform 12 disposed below the slide rail 3. A slideway 13 for facilitating the sliding of the second-level platform 12 is provided on the first-level platform 11. The slideway 13 is perpendicular to the slide rail 3. Both the pull rope 22 and the fireproof cloth 21 are connected to the second-level platform 12. The third motor is disposed on the second-level platform 12. A fire extinguishing member is provided on the lower side of the second-level platform 12. The fire extinguishing member includes a fire extinguishing gas pipe 14, a cover cloth clip 15, a gas valve provided on the fire extinguishing gas pipe 14, and a fire extinguishing cover cloth provided on the cover cloth clip 15; All the fire extinguishing members are located at the top of the space surrounded by the fireproof cloth 21; The lifting frame 2, the fireproof cloth 21, and the second-level platform 12 are all flame retardant members.

[0023] The method includes the following steps: S1: First displacement; when garage fire information is obtained, the data of the parking space where the vehicle on fire is located is obtained, and the platform is driven to displace along the slide rail to above the vehicle on fire; S2: First descent and second displacement; drive the lifting frame to descend to a preset height at a first speed; and during the first descent of the lifting frame, obtain the parking position of the vehicle on fire in real time, drive the first-level platform to displace along the slide rail and the second-level platform to displace along the slideway until the vehicle on fire is located inside and below the lifting frame; S3: Second descent and first fire extinguishing; drive the lifting frame to descend to the ground at a second speed. At this time, the fireproof cloth covers the vehicle on fire, and start the fire extinguishing component to conduct the first fire extinguishing of the vehicle on fire; S4: Second fire extinguishing; after a preset time, judge whether the temperature inside the fireproof cloth is higher than the preset temperature value. If so, start the fire extinguishing component to conduct the second fire extinguishing of the vehicle on fire; otherwise, do not perform the operation.

[0024] As one embodiment of the present invention, a first motor for driving the first-level platform to displace along the slide rail and a second motor for driving the second-level platform to displace along the slideway are provided on the first-level platform; effectively separately control the driving motors for the displacement of the lifting frame in two directions. The first motor is a high-speed motor, which can drive the entire platform to quickly displace on the slide rail to reach above the designated parking space. The second motor is a reduction motor, which can more precisely adjust the front and rear positions of the lifting frame, effectively adapting to vehicles parked in the front or rear to adjust the position; When performing step S1, only the first motor works to drive the first-level platform to displace along the slide rail to above the vehicle on fire; In addition, when performing step S2, the first motor and the second motor work simultaneously to drive the platform to displace along the slide rail and the second-level platform to displace along the slideway.

[0025] The slide rail 3 and the slideway 13 are both horizontally arranged and are perpendicular to each other. The slide rail 3 extends in the left-right direction of the vehicle, and the slideway 13 extends in the front-rear direction of the vehicle. The slide rail clamping plate 18 of the first-level platform 11 is stuck on the slide rail 3 for sliding. Most of the structure of the first-level platform 11 is located above the slide rail 3, but the edge plate of the first-level platform 11 extends downward to the lower side of the slide rail 3. A T-shaped slideway 13 is provided at the lower end of the edge plate. The T-shaped clamping plate of the second-level platform 12 just gets stuck at the T-shaped slideway 13, so that the second-level platform 12 will not fall, and the T-shaped clamping plate is a long strip plate, which just allows the T-shaped clamping plate to displace along the front-rear direction of the vehicle in the slideway 13; When performing step S2, the displacement directions of the first-level platform and the second-level platform are perpendicular until the vehicle on fire is located inside and below the lifting frame.

[0026] As one embodiment of the present invention, a vertically downward sensing component is provided on the outer side of the lifting frame; When performing step S2, when all the sensing components sense that there is no obstruction below, the vehicle on fire is located inside and below the lifting frame.

[0027] As one embodiment of the present invention, a pull rope is connected between the secondary platform and the lifting frame, and a third motor for taking in and paying out the pull rope is arranged on the secondary platform; When performing steps S2 and S3, the third motor pays out the pull rope to drive the lifting frame to descend.

[0028] As one embodiment of the present invention, the third motor is a stepless variable speed motor; and the second speed is greater than the first speed; When performing step S3, the third motor increases the output power to drive the lifting frame to descend to the ground at a second speed greater than the first speed.

[0029] As one embodiment of the present invention, the fire extinguishing member includes a gas valve and a cover cloth clip. The gas valve is arranged on the fire extinguishing gas pipe, and a fire extinguishing cover cloth is clamped and connected to the cover cloth clip; all the fire extinguishing members are located at the top of the space surrounded by the fireproof cloth 21; wherein the fire extinguishing cover cloth is arranged in the middle of the lower side of the secondary platform 12, that is, at the top of the space surrounded by the fireproof cloth. Once the cover cloth clip 15 is loosened, the fire extinguishing cover cloth falls to cover the vehicle. The fire extinguishing cover cloth is a flame-retardant and airtight member, which can cover and extinguish the vehicle; there are multiple openings of the fire extinguishing gas pipe 14 arranged on the lower side of the secondary platform 12 and evenly arranged around the fire extinguishing cover cloth. The end of the fire extinguishing gas pipe 14 is connected to a gas storage tank arranged in the secondary platform 12. After the gas valve is opened, the gas storage tank will release fire extinguishing gas through the fire extinguishing gas pipe 14 into the space surrounded by the fireproof cloth, generally inert gas or carbon dioxide, to reduce the oxygen content around the vehicle and extinguish the fire on the vehicle.

[0030] When performing step S3, the gas valve is opened to make the fire extinguishing gas in the fire extinguishing gas pipe reach the space surrounded by the fireproof cloth to conduct primary fire extinguishing on the vehicle on fire; When performing step S4, the cover cloth clip is opened to make the fire extinguishing cover cloth fall to cover the vehicle on fire to conduct secondary fire extinguishing on the vehicle on fire.

[0031] Here, there are two times of fire extinguishing on the vehicle. After the fireproof cloth descends, primary fire extinguishing is conducted on the vehicle on fire. If the vehicle on fire is a new energy vehicle or has other combustibles resulting in intense combustion, secondary fire extinguishing is conducted.

[0032] As one embodiment of the present invention, a temperature sensing member 16 is arranged at the bottom of the secondary platform; When performing step S4, the temperature inside the fireproof cloth is sensed by the temperature sensing member, and when the temperature inside the fireproof cloth is higher than the preset temperature value, the fire extinguishing member is started to conduct secondary fire extinguishing on the vehicle on fire.

[0033] As one embodiment of the present invention, a fire alarm is arranged on the secondary platform 12; When executing step S1, a first-level fire alarm information is issued; when it is obtained that there is a vehicle on fire in the garage, a first-level fire alarm is issued, and at the same time, the platform is started to move toward the location of the vehicle on fire; It should be noted that after the first fire extinguishing and after the predetermined time, when the temperature inside the fireproof cloth drops and no secondary fire extinguishing is required, the first-level fire alarm will be lifted, but the staff still needs to be reminded to confirm the loss on site and negotiate with the vehicle driver; When executing step S4, a second-level fire alarm information is issued; after the lifting frame is lowered, if a second fire extinguishing is required, it means that the fire is large and a second-level fire alarm is required, indicating that effective isolation has been carried out and firefighters are required to cooperate in the inspection, or to carry out effective fire extinguishing and remedial measures when fire prevention fails.

[0034] The invention discloses a garage fire prevention method. When a vehicle catches fire, a driving platform is displaced to above the burning vehicle, and a fireproof cloth is lowered to cover the burning vehicle. Only one fireproof platform is required to be arranged in one garage area, and the arrangement cost is low, and the vehicle entering and exiting the parking space is not affected. By adopting two descents and two displacements, the burning vehicles at various positions can be accurately covered at the fastest speed, and the burning vehicles under the cover will stop burning due to lack of oxygen through two fire extinguishing operations, and toxic and harmful gases can be effectively isolated in the fireproof cloth, and the safety is high.

[0035] The present invention is not limited to the above specific implementations, and the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made to the above implementations based on the technical essence of the present invention shall be included in the protection scope of the present invention.
