Description

Technical Field

[0001] The invention relates to a fire extinguishing hood, in particular to a fire extinguishing hood for an automobile. Background Art

[0002] Cars are the most widely used means of transportation in modern society. In recent years, as energy and environmental resources have received people's attention, new energy vehicles have been able to accelerate their development in recent years. As of mid-2018, the number of new energy vehicles in China has exceeded 2 million, which means that the production and sales of new energy vehicles will continue to increase rapidly. Therefore, the safety issues of new energy vehicles have received corresponding attention. It is known that in the past, the causes of new energy vehicle fires were caused by battery problems due to the presence of high-voltage batteries, 58% of the fires in vehicles were caused by battery problems, 19% of the fires in vehicles were caused by collision problems, and some vehicles were caused by flooding, component failures and other reasons. Therefore, how to quickly extinguish the spontaneous combustion of electric vehicles is also a difficult problem. The current default measure is to let it burn. The specific reason is that battery spontaneous combustion is not a chemical reaction between combustibles and oxygen, so the traditional fire extinguishing principle of isolating air cannot be used. Even if there is no oxygen, battery spontaneous combustion is still difficult to control, which also requires urgent technical improvement measures. At the same time, in addition to the fuel tank and oil line, other parts of the car, such as tires, car interior, etc., are all combustibles. Passengers in the car use fire illegally and carry combustibles. There are also electrical appliances and other things such as wiring harnesses in the car, which are all fire sources. In addition, some drivers lack fire safety knowledge and ignore the safety prevention of car fires, which leads to a significant increase in car fire accidents, causing serious losses to the country and people's lives and property. Therefore, when a vehicle catches fire, it is particularly important to quickly extinguish the fire to prevent greater casualties and property losses.

[0003] Especially in open parking lots, residential areas, gas stations and charging stations, liquefied gas tank distribution stations, highway service areas and other places, when a car catches fire, the rapid spread of the fire will cause unimaginable harm. At the same time, when a car catches fire, the general approach is either to use the fire extinguisher on the car to put out the fire, or to call 119 firefighters for on-site rescue, and there is no effective fire extinguishing device. As we all know, the car fire extinguisher is small in size and has weak fire extinguishing ability. If the 119 firefighters arrive, it is estimated that large casualties and property losses have already occurred. Therefore, it is imperative to invent an effective and timely fire extinguishing device.

The problem that the traditional car needs to wait for firefighters or spontaneous combustion to extinguish the fire after the fire, resulting in the loss of the opportunity to extinguish the fire and causing greater losses, is overcome. After the fire is reduced, the internal temperature of the car and the mobile frame on which the fire is extinguished can be slowly reduced by connecting the water pipe to the external water resources. At the same time, the oxygen concentration is continuously reduced, and the fire is continuously reduced and the fire is extinguished. When the fire of the car on fire has been extinguished, the rear drive device shrinks the length of the mobile frame, and after shrinking, it is driven back to an empty place by the front drive device, which greatly reduces the occupied space and is convenient to use. In addition, when the fire is not large, the fire extinguisher may be detonated only after the outer frame moves to the rear of the car on fire. The use of two sets of fire extinguishing systems can effectively and timely control the fire, and the use effect is good.

[0030] The fire extinguishing hood of the present invention is particularly applicable to places such as gas stations, charging stations, liquefied gas tank distribution stations, highway service areas, open-air parking lots, residential areas, etc. It has a wide range of application scenarios, brings great convenience to firefighters, and has a wide promotion market; specifically:

[0031] 1. The fire extinguishing cover of the present invention is configured at a gas station or charging station. When a vehicle catches fire, the device can quickly start operation to isolate the burning vehicle to prevent the fire from spreading to surrounding vehicles. When a fire occurs during refueling or charging, it can prevent the charger, gas station and other equipment from catching fire and exploding and spreading to more surrounding facilities. When multiple fire extinguishing covers are equipped at the same time, the fire extinguishing covers can provide temporary shelters for people whose lives are threatened in the area, and can also provide cover for fire extinguishers.

[0032] 2. The fire extinguishing hood of the present invention can be configured at a liquefied gas tank distribution station, which can be used as a storage room to place flammable items. When a fire occurs, it can respond in time and protect the safety of surrounding personnel.

Fire hazards occur in highway service areas, and fire rescue is often not timely. By placing the fire extinguishing cover of the present invention in the highway service area, the fire extinguishing cover of the present invention can be towed to the scene nearby when a fire occurs.

[0034] 4. With the continuous increase in the number of cars in my country, the quality and performance of vehicles vary. Fuel vehicles, pure electric vehicles, gas vehicles and other vehicles are parked in a centralized open-air manner. After a fire occurs, the fire extinguishing cover of the present invention can be used in the parking lot to quickly isolate the fire source and protect other properties from being infringed.

[0035] 5. Private vehicles, battery vehicles, etc. in residential areas are often parked in disorder, which is a high-risk place for fires. After a fire occurs, the fire extinguishing cover of the present invention can be used to quickly isolate the fire source and protect other properties from being damaged; or a fixed diamond fire extinguishing cover can be made in the charging pile area and fixed parking spots in the community to fully protect the property of the owner from accidental fire damage.

[0036] 6. In cold open-air places in the north (for example: the average winter temperature in the northeast is -20°C), the fire extinguishing hood of the present invention is set up on the basis of automatic fire extinguishing, and an electric radiator is installed inside to heat the inside of the diamond fire extinguishing hood, forming a mobile or fixed insulation shed that can play a role in heat preservation, especially for new energy vehicles, which is beneficial to the stability of the vehicle charging process.

[0037] In the present invention, a fire curtain 7 located between two front vertical pipes is installed at the upper end of the front gantry-shaped pipe, and a hook is provided at the upper end of the front gantry-shaped pipe. When traveling, the fire curtain 7 is pulled up and hung on the upper hook to avoid obstruction of vision; after the travel is completed, the fire curtain is lowered to allow the fire of the burning car to escape from the moving frame and cause damage to the components outside the moving frame.

[0038] In the present invention, a portable dry powder extinguisher 8 is installed on the mounting frame 13 and is located below the fire curtain. Preferably, two portable dry powder extinguishers 8 are provided, so that a backup fire extinguisher is provided for the entire mobile frame, so that it can be used at any time according to the fire risk situation.

[0039] In the present invention, a gas detector (not shown) can be installed outside the top of the mobile frame, with its sensing end extending into the mobile frame and used to sense gas. The output end of the gas detector is electrically connected to a gas sensing alarm. In this way, if flammable and explosive gas leaks from the mobile frame during the fire extinguishing process, an alarm can be issued to ensure timely rescue.

[0040] In the present invention, a Y-type filter is arranged in the water spray pipeline to filter impurities in the pipeline and avoid blockage due to a small diameter nozzle.

[0041] In the present invention, handrails 128 are welded to the vertical bars on the left and right sides of the front end of the outer frame 12, so that in the unexpected situation that the electric drive system of the mobile frame fails, the handrails can be used to manually push the cart to the fire scene.

[0042] In the present invention, a working power supply and a control system for controlling the operation of the entire mobile frame are installed on the mounting frame. The working power supply is a lithium iron phosphate lithium ion power supply, and the control system uses a "one-to-two" control system.

[0043] In the present invention, outer guide wheel tracks 91 extending in the front-to-back direction are installed on the left and right outer side walls of the inner frame 11, and inner guide pulleys 92 located in the outer guide wheel tracks and sliding along the outer guide wheel tracks are installed on the left and right vertical rods at the front end of the outer frame 12 corresponding to the outer guide wheel tracks; inner guide wheel tracks 93 extending in the front-to-back direction are installed on the left and right inner side walls of the outer frame 12, and outer guide pulleys 94 located in the inner guide wheel tracks and sliding along the inner guide wheel tracks are installed on the left and right vertical rods at the rear end of the inner frame corresponding to the inner guide wheel tracks.
