[0002] In order to improve the efficiency and effect of fire extinguishing of burning cars, car fire extinguishing hoods have appeared on the market. The fire extinguishing hoods can seal the burning car and isolate the burning car. Especially for places where cars are parked in a concentrated manner, such as roll-on / roll-off ship cabins, garages and other places, the fire extinguishing hoods can effectively isolate the burning car from other cars. It is only necessary to spray water on the burning car to cool it down and extinguish the fire, thereby preventing the fire from spreading and achieving rapid fire extinguishing.

[0003] However, there are great risks in manually covering the car with a fire hood, especially in car concentrated parking areas such as roll-on / roll-off ship cabins and garages. Since the vehicles are very close to each other, there is little space for manual operation to safely cover the burning car with a fire hood. The burning vehicle can easily ignite nearby vehicles, posing a great safety hazard. Utility Model Content

DETAILED DESCRIPTION

[0020] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] like Figure 1 , Figure 2 As shown, a driving and positioning device for a fire extinguishing hood for a car in a garage or a ro-ro cabin includes a rigid track 7 and two load-bearing steel cables 1 arranged on the top of the garage or the ro-ro cabin. The two load-bearing steel cables 1 are arranged at the same height and in parallel. A steel cable winch 18 is anchored at each end of each load-bearing steel cable on the top of the ro-ro cabin. The two ends of each load-bearing steel cable 1 are respectively wound on the drum of the corresponding steel cable winch 18 to tighten and straighten the load-bearing steel cable 1. The two steel cable winches 18 cooperate to enable the load-bearing steel cable 1 to move back and forth between the two drums. The rigid track 7 spans across the two load-bearing steel cables 1 and is fixed to the two load-bearing steel cables 1. Driven by the load-bearing steel cables 1, the rigid track 7 can move along the arrangement direction of the load-bearing steel cables 1. A trolley 3 is arranged on the rigid track 7. The trolley 3 matches the travel drive motor 2 to provide power for the trolley 3 to move along the rigid track 7.

[0022] A wire rope vertical hoisting mechanism is respectively provided on the left and right sides of the trolley 3 through a connecting frame. The wire rope vertical hoisting mechanism comprises two wire rope winding wheels 6 and a double-axis motor 4. The two wire rope winding wheels 6 are concentric and arranged in sequence along the moving direction of the trolley. A wire rope 8 is wound around each wire rope winding wheel 6. The two wire rope winding wheels 6 are mounted on two motor shafts 5 of the double-axis motor 4. The double-axis motor 4 drives the two wire rope winding wheels 6 to rotate synchronously, so that the wire ropes 8 wound around the two wire rope winding wheels 6 are lowered or wound at the same speed. A hoisting frame 13 is provided under the trolley 3, and the steel wire rope 8 is vertically downward, and its lower end is connected and fixed to the hoisting frame 13. At this time, the hoisting frame 13 is hoisted on the trolley 3 through four steel wire ropes 8, and a hook 14 is provided on the hoisting frame 13. The fire extinguishing hood is hoisted by the hook 14 to put the fire extinguishing hood in a combat standby state. Once a fire is discovered, the fire extinguishing hood is driven by the device to move and lower in the garage and the roll-on / roll-off ship cabin, so as to quickly seal and isolate the burning cars in the area.

[0023] In the present invention, the hoisting frame 13 is preferably a square frame structure, and its internal area, that is, the area surrounded by the four frames of the square frame, is larger than the cross-sectional size of the fire extinguishing hood, ensuring that the fire extinguishing hood is horizontally deployed in an emergency state. Because when hoisting the fire extinguishing hood 17 that is vertically compressed and folded, can be filled with water, and is made of flexible materials, the lifting point of the fire extinguishing hood 17, that is, the position of its flexible lifting ring 16 is set close to the bottom surface of the fire extinguishing hood 17. When the fire extinguishing hood 17 is lowered to the burning car until the bottom surface of the fire extinguishing hood 17 and the garage and the floor of the roll-on / roll-off ship are in contact, during the lowering process of the fire extinguishing hood 17, the valve of the fire hose 22 connected to the fire hose interface 11 of the fire extinguishing hood 17 is opened, and fire water or fire extinguishing agent (water-quality extinguishing agent) is filled into the fire extinguishing hood 17. Fire extinguishing agent), since the internal area of ​​the lifting frame 13 is larger than the cross-sectional size of the fire extinguishing hood, it makes way for the compressed fire extinguishing hood 17 to expand upward, ensuring that the compressed fire extinguishing hood 17 is expanded and opened upward after being filled with water, so as to seal and isolate the burning car. At the same time, the fire extinguishing agent or fire-fighting water filled in the fire-fighting hood 17 is sprayed toward the burning car through the nozzle of the fire-fighting hood to cool down and extinguish the fire. The sprayed fire-fighting water or fire-extinguishing agent quickly forms a pool in the fire-fighting hood, directly immersing the battery at the bottom of the car in water and quickly extinguishing the fire.

[0024] In the utility model, video fire detectors 12 are arranged around the hanging frame 13, and fire detectors such as temperature detectors and / or smoke detectors and / or infrared detectors are arranged at the lower end of the hanging frame 13. All the above fire detectors are connected to the control terminal, that is, the regional automatic fire fighting workstation system and communicate data. At the same time, the motor driving the trolley, that is, the travel drive motor 2, the motor driving the steel cable winch 18 and the motor driving the steel wire rope winding wheel, and the valve of the fire hose connected to the fire extinguishing hood are connected to the control terminal cable respectively. The change of the spatial position of the fire extinguishing hood suspended and pulled by the hanging frame 13 is realized by the cooperation of the motor. The cooperation drive of the motor depends on the fusion judgment of multiple information sensors such as temperature, video, infrared, etc. According to the spatial grid coordinates of the protection area, the positioning coordinate information of the burning car is transmitted to the execution motor and the fire extinguishing agent control system of the fire station in the protection area, and the fire extinguishing agent or fire water is filled and sprayed while the compressed fire extinguishing hood is moved to the position above the burning car.

[0025] Working principle of the utility model: Use the utility model to hoist the fire extinguishing hood 17 so that it is suspended in the upper space of the garage and the roll-on / roll-off ship cabin, ready for battle. When the fire extinguishing hood 17 is a flexible fire extinguishing hood, compress the fire extinguishing hood vertically, fold it and then hoist it, and keep the fire extinguishing hood and the fire hose in the garage and the roll-on / roll-off ship cabin connected. When the fire detector finds that there is a car on fire in the area, the regional automatic fire fighting workstation system determines the location of the fire point and issues a corresponding instruction. The corresponding execution motor is turned on to move the hoisted fire extinguishing hood 17 to the top of the burning car, and then lower the fire extinguishing hood 17, and cover the fire extinguishing hood 17 downward on the burning car, isolate the burning car and then extinguish the fire. The programmatic association and integration of the utility model and the fire extinguishing hood make it possible to realize a fully automatic unmanned disposal security system for preventing car fires in parking lots such as garages and roll-on / roll-off ship cabins.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
