Description

Technical Field

[0001] The present invention relates to the technical field of fire fighting equipment, in particular to a mobile lithium battery electric vehicle rapid fire extinguishing device and a fire extinguishing method. Background Art

[0002] With the rapid growth of production, sales and ownership of new energy vehicles, the risk of fire accidents caused by them has become increasingly prominent. As the core component of new energy vehicles, high-voltage batteries have complex cell group structures, and their electrochemical performance and stability are quite different from those of traditional fossil fuels. There is a possibility of battery fire during driving, and the fire prevention and control of lithium batteries and the selection of fire extinguishing agents are completely different from those of traditional vehicles. Taking effective lithium battery fire prevention and control measures that can be moved to any position is of great practical significance for reducing the fire risk of new energy vehicles.

[0003] Since the lithium battery components of new energy vehicles are mostly enclosed in the vehicle chassis, the fire extinguishing agent cannot directly contact the fire site after a fire occurs, making it more difficult to control the fire in the early stages. Once the fire spreads, the difficulty of extinguishing the fire increases further, and the losses caused by the fire increase further.

[0004] Therefore, how to provide a mobile lithium battery electric vehicle rapid fire extinguishing device and fire extinguishing method is a problem that technical personnel in this field urgently need to solve. Summary of the invention

[0007] A mobile lithium battery electric vehicle rapid fire extinguishing device, comprising a mobile fire extinguishing vehicle body;

[0008] Wherein, the mobile fire-fighting vehicle body comprises a first vehicle body and a second vehicle body;

[0009] A fire extinguishing agent storage tank and a demolition agent storage tank are provided on the first vehicle body, and a plurality of fire extinguishing agent nozzles and a plurality of demolition agent nozzles are provided above the second vehicle body;

[0010] The fire extinguishing agent nozzle and the demolition agent nozzle are both fixed on the track, and the fire extinguishing agent nozzle and the demolition agent nozzle can move forward and backward.

[0012] The outlet of the demolition agent storage tank is connected to a demolition agent pump, and the outlet of the demolition agent pump is connected to a plurality of demolition agent nozzles through a conveying pipe disc;

[0013] An on-board battery is fixed in the mobile fire-fighting vehicle body, the on-board battery is electrically connected to the fire-extinguishing agent pump and the demolition agent pump, and the on-board battery provides power for the mobile fire-fighting vehicle.

[0014] Furthermore, it also includes a load-bearing controller

[0015] The load-bearing controller is fixed to the rear of the first vehicle body, and the load-bearing controller is electrically connected to the vehicle-mounted battery.

[0016] Furthermore, a Bluetooth module or a wireless module is provided in the load-bearing controller; the load-bearing controller is connected to the control terminal via an electrical signal via the Bluetooth module or the wireless module.

[0017] Furthermore, the control terminal is a mobile phone, a tablet or a computer.

[0018] The mobile lithium battery electric vehicle rapid fire extinguishing device is controlled by a control terminal; the control terminal controls the front, back, left, right, up and down movement of the vehicle body through a load-bearing controller;

[0019] The control terminal controls the demolition agent material pump through the load-bearing controller, thereby controlling the pressure and flow of the demolition agent nozzle.

[0020] The control terminal controls the fire extinguishing agent pump through the load-bearing controller, thereby controlling the injection pressure and flow rate of the fire extinguishing agent nozzle.

[0021] Further, the fire extinguishing agent is a water-based fire extinguishing agent;

[0022] The demolition agent is water.

[0023] In the technical solution of the present invention, all the spray heads can be adjusted by 180 degrees, and the wheels of the spray head vehicle are much smaller than those of the tank loading vehicle.

[0024] The present invention also provides a method for quickly extinguishing a fire in a mobile lithium battery electric vehicle, using the above-mentioned fire extinguishing device, comprising the following steps:

[0025] (1) After a lithium battery electric vehicle catches fire, move the fire extinguisher to the burning electric vehicle, push the fire extinguisher to the ground under the battery compartment of the vehicle and secure it with a hydraulic or pneumatic device;

[0026] (2) Start the fire extinguishing agent pump and the demolition agent pump at the same time. The fire extinguishing agent nozzle sprays the fire extinguishing agent onto the surface of the battery compartment. The demolition agent pump sprays the demolition agent and moves the bottom plate of the demolition battery compartment. Then the fire extinguishing agent directly contacts the lithium battery to extinguish the fire until the lithium battery stops burning.
