Description

Technical Field

[0001] The invention relates to the field of fire extinguishing equipment, in particular to a water-injected portable fire-proof and extinguishing isolation cover. Background Art

[0002] The new energy sector is an emerging industry, and its fire extinguishing devices mostly rely on traditional fixed fire-fighting facilities, which are difficult to cope with the characteristics of new energy fires, which develop rapidly, consume a lot of water, and are easy to spread. At present, the technologies for new energy fire extinguishing are mainly divided into the following aspects:

[0003] 1. Isolation

[0004] 1. Use large machinery to transfer the burning materials to a safe area; 2. Use fixed fire-fighting facilities such as fire blankets and fire extinguishing boxes to cover the burning materials; 3. Use fire-proof roller curtains to isolate the fire area;

[0005] 2. Fire Extinguishing

[0006] 1. Set up a large number of fixed fire-fighting facilities around the cargo. Once a fire occurs, spray a large amount of fire extinguishing agent on the burning material to cool it down and extinguish the fire; 2. Use the bottom piercing jet technology of the car to extinguish the fire and cool the battery pack at the bottom of the vehicle; 3. Use the cofferdam technology to immerse the battery pack to extinguish the fire;

[0007] 3. Prevention

[0008] 1. Install temperature and smoke sensors in the monitoring area to predict fire in advance; 2. Use infrared cameras for monitoring.

[0009] However, the patents in the prior art have the following disadvantages:

[0010] 1. Disadvantages of fire blanket: 1. Single function, can only play the role of suffocation and isolation; 2. Long disposal time, belongs to passive fire extinguishing; 3. It is not easy to observe the fire situation; 4. It is easy to reignite; 5. People are easily injured when covered at close range.

[0011] 2. Disadvantages of cofferdam technology: 1. It cannot completely isolate the burning vehicle and can only soak the lower part of the vehicle; 2. When placing the device, people are easily burned by smoke or jet fire; 3. It cannot be used for vehicles that are in the fire development stage.

[0012] 3. Disadvantages of car cooling fire blanket: 1. It is easy to cause rescue water to pollute the environment; 2. Only a circle of water curtain hose at the bottom sprays water to extinguish the fire, and the fire extinguishing effect on the main three-dimensional fire and battery chassis fire of new energy vehicles is very limited; 3. It is difficult to observe the fire situation; 4. It is easy to re-ignite; 5. People are easily injured when covered at close range;

[0013] 4. Disadvantages of a car fire blanket with built-in water spray cooling function: 1. The device is heavy and difficult for people to carry and operate; 2. The equipment wires and water pipe interfaces are easily damaged; 3. It is easy to cause rescue water to pollute the environment; 4. It is difficult to observe the fire situation; 5. It is easy to re-ignite; 6. People are easily injured when covered at close range. Summary of the invention

[0014] The technical problem to be solved by the present invention is to overcome the above technical defects and provide a lightweight and portable device that can be widely used in compact parking spaces such as parking lots, underground garages, and roll-on / roll-off ship cargo holds where large equipment is difficult to enter.

[0015] In order to solve the above problems, the technical solution of the present invention is: a water-injected portable fire-proof isolation cover, including a fire blanket and a channel injection pipe, a sprinkler head pipe and a bracket pipe;

[0016] The fire blanket is a conical structure, and the channel injection pipes are distributed at the bottom and the inner side. The upper end of the channel injection pipe is connected with a connector, and the other section of the channel injection pipe is distributed inside and is provided with a plurality of evenly distributed water spray heads. A storage cover is provided on the top of the fire blanket, and supporting devices are provided around the channel injection pipe. The supporting device includes a fixing ring, which is sleeved on the channel injection pipe and is connected with a supporting frame. The end of the supporting frame is connected with a supporting head connected to the fire blanket. The bracket pipe is fixedly connected to the fire blanket, and water injection ports are provided on the water spray head pipe and the bracket pipe.

[0017] Furthermore, the fire blanket is a conical structure.

[0018] Furthermore, a plurality of evenly distributed water spray heads are arranged on the water spray head pipeline.

[0019] Furthermore, the fire blanket is provided with an observation window, and the observation window is made of transparent fireproof material.

[0020] Furthermore, a rubber suction cup is provided at the bottom of the inner cavity of the storage cover to fix the device and prevent displacement when unfolding.

[0021] The advantages of the present invention compared with the prior art are:

[0022] The present invention extinguishes a three-dimensional automobile fire by spraying water all around, effectively controlling the three-dimensional automobile fire; it is convenient to observe the internal situation, and the top is spliced ​​with a transparent fireproof material, which is convenient for checking the internal fire situation and preventing a large amount of air from rushing in when the isolation cover is opened for observation, resulting in re-ignition;

[0023] Immersion fire extinguishing prevents re-ignition. The bottom uses its own structure to form a closed space to achieve the effect of a cofferdam, immersing the battery pack at the bottom of the vehicle to extinguish the fire, and at the same time can effectively prevent the re-ignition. The operation is simple. You only need to connect the device to the water pipe and place it on the top of the burning vehicle. After the device is filled with water, it will automatically cover the vehicle to extinguish the fire;

[0024] To protect the operator, the operator can place the device on the roof outside the danger zone with a long pole, without having to get close to the vehicle, thus avoiding the risk of injury and facilitating maintenance. The device has a simple structure and only needs to be rinsed and dried, with low maintenance costs;

[0025] Meet the use requirements of different scenarios. The device is lightweight and portable, and can be widely used in parking lots, underground garages, ro-ro cargo warehouses and other compact parking spaces where large equipment is difficult to enter; it can also be used in automobile showrooms in large shopping malls to deal with sudden vehicle fires. When not in use, it can be placed in an emergency box without affecting the appearance of the showroom; it can also be fixed above the charging pile to quickly deal with sudden fires in charging vehicles and other scenarios to protect the environment. When using this device, the fire-fighting water is located in the isolation device, which will not cause the dispersion of wastewater. After the accident is handled, the wastewater can be effectively recycled and treated, reducing the secondary harm caused by the accident to the environment. BRIEF DESCRIPTION OF THE DRAWINGS
