Description

Technical Field

[0001] The invention belongs to the technical field of fire-fighting equipment, and in particular relates to a fire-fighting system that can penetrate deep into a vehicle chassis. Background Art

[0002] Fires in new energy vehicles are a safety issue that needs attention. The lithium battery used in electric vehicles is a high-energy-density energy carrier, which may experience thermal runaway due to short circuit, overcharging, collision, aging or external factors, thus causing a fire. Once the fire spreads to surrounding buildings, vehicles, trees or other facilities, it may trigger a chain reaction and cause wider property losses. However, battery fires are more challenging to extinguish than traditional vehicle fires. Once the battery of an electric vehicle catches fire, it is often difficult to extinguish. It is necessary to extinguish the fire immediately when the fire point is first discovered, otherwise the fire will become larger and cannot be effectively and quickly extinguished.

[0003] The existing fire extinguishing methods for new energy vehicles are as follows: First, a fire sprinkler is connected above the parking space. When the fire alarm is triggered, the fire water passes through the fire sprinkler to extinguish the fire from top to bottom; second, the firefighters go to the burning new energy vehicle and use the fire water in the fire truck to spray from the side to extinguish the fire. The battery pack of the new energy vehicle is on the chassis of the vehicle. The existing fire extinguishing methods cannot directly transport the fire water to the fire point, so it is impossible to achieve rapid fire extinguishing. Firefighting in the traditional way requires a high-pressure water source and is only suitable for firefighting in buildings. It is difficult to set up an independent outdoor area. There is a certain delay for firefighters to rush to the scene, and they will miss the best time to extinguish the fire. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a fire extinguishing system that can penetrate deep into the chassis of a vehicle.

[0005] The technical solution adopted to solve the above technical problems is: a fire extinguishing system that can penetrate into the chassis of a vehicle, comprising a bottom plate, a water tank is fixedly connected to the top center of the bottom plate, and L-shaped pipes are fixedly connected to one side of the front and rear ends of the top of the bottom plate;

[0006] The tops of the outer ends of the two L-shaped tubes are fixedly connected with a first U-shaped tube, one side of the two first U-shaped tubes is provided with a second U-shaped tube, and one side of the two L-shaped tubes is provided with a third U-shaped tube;

[0007] Two connecting mechanisms are installed between the two L-shaped tubes and the third U-shaped tube, and between the two first U-shaped tubes and the corresponding second U-shaped tubes, and a water spraying mechanism is installed on one side of the water tank.

[0008] Furthermore, the outer walls of the two L-shaped tubes, the two first U-shaped tubes, the two second U-shaped tubes and the third U-shaped tube are all fixedly connected with a plurality of nozzles, and the plurality of nozzles on the third U-shaped tube are located at the top of the outer wall thereof.

[0009] Through the above technical solution, when fire extinguishing is required, the water in the water tank flows to the L-shaped tube through the water spraying mechanism, and is transported to the connected third U-shaped tube through the L-shaped tube, and the fire is extinguished on the bottom of the car through multiple nozzles. At the same time, the water is transported to the connected first U-shaped tube through the L-shaped tube, and then transported to the connected second U-shaped tube. Finally, the fire is extinguished on the side of the car through multiple nozzles, thereby realizing multi-directional fire extinguishing, and it is a bottom-up fire extinguishing method with fast fire extinguishing efficiency.

[0010] Furthermore, a plurality of universal wheels are installed at the bottom of the bottom plate, the two L-shaped tubes, the two second U-shaped tubes and the third U-shaped tube.

[0011] Through the above technical solution, the entire fire extinguishing system can be moved at will through multiple universal wheels, so it is easy to carry and has strong flexibility. It can be moved into a parking space so that the car can be parked in the middle of the fire extinguishing system.

[0012] Furthermore, temperature sensors are installed at the inner ends of the outer walls of the two second U-shaped tubes and the top end of the outer wall of the third U-shaped tube.

[0013] Through the above technical solution, when the side and bottom of the car are on fire, the corresponding temperature sensor will send a signal, thereby starting the water spray mechanism to extinguish the fire on the side and bottom of the car. The multi-point detection method can achieve rapid response, rapid triggering, and timely fire extinguishing.

[0014] Furthermore, a plurality of annular limiting grooves are formed on the outer walls of the two first U-shaped tubes, and a plurality of clamping grooves are formed on the outer walls of the two first U-shaped tubes at positions close to the annular limiting grooves.

[0015] Through the above technical solution, the annular limiting groove is used to quickly position the connecting mechanism, so that its internal parts can be quickly engaged with the slot, thereby quickly adjusting the first U-shaped tube, the second U-shaped tube and the third U-shaped tube.

[0016] Furthermore, both ends of the two second U-shaped tubes are provided with a first thread groove.

[0017] The above technical solution facilitates the connection between the first U-shaped tube and the second U-shaped tube, while also improving the connectivity.

[0018] Furthermore, the connecting mechanism includes a connecting sleeve, an annular opening is provided on one side of the inner wall of the connecting sleeve, an annular spring strip is fixedly connected to the center of the annular opening, one end of the connecting sleeve is fixedly connected to a first threaded sleeve, a second threaded groove is provided on the outer wall of the connecting sleeve, a plurality of mounting grooves are provided on one side of the outer wall of the connecting sleeve, the inner ends of the plurality of mounting grooves are fixedly connected to springs, the outer ends of the plurality of springs are fixedly connected to connecting plates, the centers of the plurality of connecting plates are fixedly connected to limiting pins, the outer wall of the connecting sleeve is threadedly connected to a second threaded sleeve through the second threaded groove, and a push ring is fixedly connected to one side of the second threaded sleeve.

[0019] By the above technical scheme, when adjusting the length of the second U-shaped tube, first loosen the second threaded sleeve to drive the push ring away from the first threaded sleeve. At this time, the multiple limit pins extend to the outer ends under the action of the spring, so that the inner ends of the multiple limit pins are away from the slots. At this time, the second U-shaped tube can be pulled, and the connected first threaded sleeve can also be driven. When the second U-shaped tube is adjusted to a specified position, the annular spring bar is fitted with the annular limit groove. At this time, the inner ends of the multiple limit pins are aligned with the multiple slots on the outer wall of the first U-shaped tube. Then, the second threaded sleeve is tightened to make the push ring approach the first threaded sleeve, so that one end of the push ring pushes the outer ends of the multiple limit pins. Since one end of the push ring and the outer ends of the limit pins are both arc surfaces, the multiple limit pins are contracted when pushed, so that they are inserted into the corresponding slots, thereby realizing the limit connection of the first U-shaped tube. Similarly, the length of the third U-shaped tube can be adjusted, so that the fire extinguishing system frame becomes longer, so that it can be used for cars of different lengths, and the functionality is strong.

[0020] Furthermore, the annular spring strip is fitted with the corresponding annular limit groove, the first threaded sleeve is threadedly connected to the corresponding first thread groove, the multiple connecting plates are slidably connected to the corresponding mounting grooves, the inner ends of the multiple limit pins are inserted into the corresponding card grooves, and the outer ends of the multiple limit pins are fitted with the corresponding inner walls of the push rings.

[0021] Through the above technical solution, in the process of pulling the second U-shaped tube, the annular spring bar is pressed and squeezed by the first U-shaped tube, so that the annular spring bar is deformed and fits with the annular limiting groove through elastic action when it is aligned with the annular limiting groove.

[0022] Furthermore, the water spraying mechanism includes two water pumps fixedly installed on one side of the water tank, a first connecting pipe is fixedly connected between the two water pumps and the water tank, and a second connecting pipe is fixedly connected between the two water pumps and the corresponding L-shaped pipes.

[0023] Through the above technical solution, when extinguishing a fire, two water pumps are started, so that the two water pumps draw water from the water tank through the connected first connecting pipe, and then transport it to the corresponding first U-shaped tube through the connected second connecting tube, and then transport it to the corresponding second U-shaped tube and third U-shaped tube, and then use multiple nozzles to extinguish the fire on the bottom and outside of the car, so that the fire can be extinguished in the first time to prevent the fire from getting bigger.

[0024] The beneficial effects of the present invention are as follows: (1) By designing the first U-shaped tube, the second U-shaped tube, the third U-shaped tube and the water spraying mechanism, when the bottom or the outside of the car is on fire, the bottom and the outside can be extinguished immediately, and the fire extinguishing method is from bottom to top, which has high fire extinguishing efficiency and prevents the fire from getting bigger; (2) By designing the connecting mechanism, the second U-shaped tube and the third U-shaped tube can be quickly adjusted, so that the entire fire extinguishing system frame can be lengthened, so that it can be used for cars of different lengths, and has strong functionality.
