Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishing equipment and is a vehicle chassis fire extinguishing mobile frame. Background Art

[0002] In recent years, the new energy industry has developed rapidly. Among them, lithium-ion batteries have been widely used due to their high energy density and long life. The number of lithium-based new energy vehicles in my country has also shown an upward trend year by year. However, under conditions of thermal abuse, electrical abuse, and mechanical abuse, lithium-ion batteries are prone to thermal runaway in single cells, and even cause thermal runaway of the entire battery module, resulting in frequent vehicle fire and explosion accidents. There are no better fire-fighting measures for power battery fires. Traditional fire extinguishing agents such as dry powder, carbon dioxide, and heptafluoropropane can extinguish battery fires, but the cooling effect is poor. High-temperature batteries still heat adjacent batteries, which can easily cause thermal runaway of adjacent batteries. Eventually, thermal runaway propagates within the module.

[0003] At present, water is the main method of firefighting for new energy vehicles. However, since the battery compartment is at the bottom of the car, it is difficult for water to enter the battery compartment and directly act on the battery. The water utilization efficiency is relatively low, and it is difficult to effectively extinguish the fire point. The jet water is basically dispersed by the car body or cooled on one side in the car, so that the battery pack at the bottom of the car cannot be effectively cooled. Summary of the invention

[0004] The utility model provides a vehicle chassis fire extinguishing mobile frame, which overcomes the deficiencies of the above-mentioned prior art and can effectively solve the problem that it is difficult to effectively extinguish the fire point at the bottom of the vehicle after the existing new energy vehicle catches fire.

[0005] The technical solution of the utility model is achieved through the following measures: a vehicle chassis fire extinguishing mobile frame includes a fire extinguishing annular pipe, a water inlet pipe, a water outlet nozzle and moving wheels, a water inlet hole is provided in the middle of the front side of the fire extinguishing annular pipe, a water inlet pipe is fixedly installed on the front side of the fire extinguishing annular pipe corresponding to each water inlet hole position, a plurality of water outlet holes are arranged at intervals on the upper side of the fire extinguishing annular pipe, a water outlet nozzle is fixedly installed on the upper side of the fire extinguishing annular pipe corresponding to each water outlet hole position, and a plurality of moving wheels are provided on the lower side of the fire extinguishing annular pipe.

[0006] The following are further optimizations and / or improvements to the above utility model technical solution:

[0007] The fire extinguishing annular pipe may be in the shape of a rectangular ring.

[0008] The above-mentioned water outlet nozzle may include a straight nozzle, a first oblique nozzle, a second oblique nozzle, a third oblique nozzle and a fourth oblique nozzle. At least two straight nozzles are arranged at intervals on the left and right sides of the upper rear side of the fire-extinguishing ring-shaped pipe; at least two first oblique nozzles are arranged at intervals on the front and back sides of the upper left side of the fire-extinguishing ring-shaped pipe, each of which is inclined to be higher on the left and lower on the right. A second oblique nozzle is arranged on the upper left side of the fire-extinguishing ring-shaped pipe between every two adjacent first oblique nozzles, and each of which is inclined to be lower on the left and higher on the right; at least two third oblique nozzles are arranged at intervals on the front and back sides of the upper right side of the fire-extinguishing ring-shaped pipe, each of which is inclined to be higher on the left and lower on the right. A fourth oblique nozzle is arranged on the upper right side of the fire-extinguishing ring-shaped pipe between every two adjacent third oblique nozzles, and each of which is inclined to be lower on the left and higher on the right.

[0009] The above may also include support rods, and at least two support rods are arranged at intervals between the left part of the fire extinguishing annular pipe and the right part of the fire extinguishing annular pipe.

[0010] The above-mentioned device may also include a water mist nozzle, and a water mist nozzle is arranged at the upper end of the water outlet nozzle pipe.

[0011] The above may also include a water hose joint, and the front end of the water inlet pipe is fixedly installed with a water hose joint.

[0012] The above-mentioned moving wheel may include a wheel frame and a moving wheel. At least two wheel frames are fixedly installed at a front-to-back interval on the lower left side of the fire extinguishing annular pipe and the lower right side of the fire extinguishing annular pipe, and the moving wheel is rotatably installed in the wheel frame.

[0013] The utility model has a reasonable and compact structure and is easy to use. By arranging movable wheels, the fire extinguishing annular pipe can be pushed to an appropriate position under the chassis of the vehicle to effectively extinguish the fire and cool the fire point. By arranging a water hose joint, the water inlet pipe and the water hose can be quickly connected together. By arranging multiple water outlet nozzles and water mist nozzles, all-round coverage spraying of the bottom of the vehicle can be achieved, which has the characteristics of fast, stable and good fire extinguishing and cooling effects.
