Description

Technical Field

[0001] The present invention relates to the field of fire extinguishing devices, and in particular to a new energy vehicle electric vehicle chassis puncture fire extinguishing device. Background Art

[0002] There are slight differences depending on the type of electric vehicle. In a pure electric vehicle equipped with only a power battery, the power battery serves as the sole power source for the vehicle's drive system. In a hybrid vehicle equipped with a traditional engine (or fuel cell) and a power battery, the power battery can serve as both the main power source for the vehicle's drive system and an auxiliary power source. It can be seen that at low speeds and when starting, the power battery serves as the main power source for the vehicle's drive system; when accelerating at full load, it serves as an auxiliary power source; and when driving normally or decelerating or braking, it serves as an energy storage.

[0003] During the use of new energy vehicle batteries, there is a risk of fire due to environmental factors and quality factors. The main reasons are:

[0004] Improper operating temperature. The electrolyte inside the battery will release a large amount of gas and heat under high temperature conditions. If the vehicle is used for a long time in a high temperature environment, the cooling system fails, or the ambient temperature is too high during charging, the battery temperature may rise abnormally and cause thermal runaway. For example, in the hot summer, the battery temperature may rise sharply after the vehicle is parked outdoors for a long time in the sun.

[0005] Production quality. The batteries used in some pure electric vehicles are not of good quality and may have flaws or defects during the production process, such as substandard quality of the electrode materials and diaphragms inside the battery, which may increase the possibility of fire.

[0006] At present, when a fire occurs in a new energy vehicle battery, the fire is mostly extinguished by spraying fire water. This method can only extinguish the fire on the surface of the new energy vehicle battery, but cannot extinguish the fire inside the new energy vehicle battery, and cannot extinguish the fire quickly and thoroughly, which has certain defects. Summary of the invention

[0007] The purpose of the present invention is to provide a new energy vehicle electric vehicle chassis puncture fire extinguishing device to achieve synchronous fire extinguishing inside and outside the new energy vehicle battery, thereby quickly and completely extinguishing the new energy vehicle battery.

[0008] In order to solve the above technical problems, the present invention provides a new energy vehicle electric car chassis puncture fire extinguishing device, including a pipe support frame, a lifting member and a puncture head;

[0010] The lifting member is fixedly mounted in the middle of the pipe support frame, and the lifting member is used to drive the puncture head to perform lifting movement;

[0011] The puncture head is installed at the driving end of the lifter. A water spray hole is arranged on the puncture head. The puncture head is lifted by the lifting member and punctures and sprays water on the battery.

[0012] Furthermore, the pipeline support frame includes a main water inlet pipe, a secondary support pipe and a plugging connection strip;

[0013] A plurality of auxiliary support pipes are arranged in parallel, and the auxiliary support pipes are vertically connected to the main water inlet pipe;

[0014] The plugging connection strip is fixedly connected to one end of the secondary support pipe away from the main water inlet pipe, and the plugging connection strip blocks the end of the secondary support pipe.

[0015] Furthermore, two connecting frames are symmetrically installed on the main water inlet pipe, and hand push frames are detachably installed on the two connecting frames.

[0016] Furthermore, a connecting pipe interface is installed on the main water inlet pipe, and the connecting pipe interface is connected to the fire water pipeline.

[0017] Furthermore, the secondary support tube is provided with a plurality of cooling water holes at equal intervals along the vertical diameter direction, and the cooling water holes are used for spraying water to cool the outside of the battery.

[0018] Furthermore, a mounting plate is fixedly arranged between two adjacent auxiliary support tubes, and a universal wheel is fixedly installed on the bottom surface of the mounting plate.

[0019] Furthermore, the top end of the plugging connecting strip is inclined and is used to guide the pipeline support frame to move below the new energy vehicle battery.

[0020] Furthermore, the lifting member has a driving joint, and a connecting pipe is detachably provided on the driving joint, and one end of the connecting pipe away from the driving joint is connected to a hydraulic driving member.

[0026] Figure 2 It is a schematic diagram of the top view of the structure of the chassis puncture fire extinguishing device of the new energy vehicle electric car of the present invention. DETAILED DESCRIPTION

[0027] The new energy vehicle electric vehicle chassis puncture fire extinguishing device of the present invention will be described in more detail below in conjunction with a schematic diagram, wherein a preferred embodiment of the present invention is shown, and it should be understood that those skilled in the art can modify the present invention described herein while still achieving the advantageous effects of the present invention. Therefore, the following description should be understood as being widely known to those skilled in the art, and not as a limitation of the present invention.

[0028] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description and claims. It should be noted that the drawings are in very simplified form and in non-precise proportions, and are only used to facilitate and clearly assist in illustrating the purpose of the embodiments of the present invention.

[0029] like Figure 1 and Figure 2 As shown, an embodiment of the present invention proposes a new energy vehicle electric vehicle chassis puncture fire extinguishing device, including a pipe support frame, a lifting member 1 and a puncture head 2.

[0030] Specifically, the pipe support frame is used to support and install the lifting member 1 and the piercing head 2 , and to transport fire-fighting water to the piercing head 2 .

[0031] The lifting member 1 is fixedly installed in the middle of the pipe support frame, and the lifting member 1 is used to drive the piercing head 2 to perform lifting movement.

[0032] The puncture head 2 is installed at the driving end of the lifter. A water spray hole 3 is provided on the puncture head 2. The puncture head 2 is lifted by the lifting member 1 and punctures and sprays water on the battery.

[0033] In this embodiment, when a fire occurs in the battery chassis of the new energy vehicle, first, the pipe support frame is moved to the bottom of the battery chassis of the new energy vehicle. Then, the puncture head 2 is lifted up by the lifting member 1, so that the puncture head 2 punctures the battery chassis of the new energy vehicle and enters the inside of the battery chassis of the new energy vehicle. Finally, the pipe support frame and the puncture head 2 respectively spray water on the outside and inside of the battery chassis of the new energy vehicle to extinguish the open flame in the fire, thereby achieving the purpose of eliminating the fire.

[0034] Since the fire extinguishing device enters the battery chassis of the new energy vehicle by puncturing, it can extinguish the fire inside the battery chassis of the new energy vehicle. At the same time, the pipe support frame can extinguish the fire outside the battery chassis of the new energy vehicle. The combination of the two has a good fire extinguishing effect.

[0035] Furthermore, the pipeline support frame includes a main water inlet pipe 4 , a secondary support pipe 5 and a sealing connection strip 6 .

[0036] Specifically, a plurality of auxiliary support pipes 5 are arranged in parallel, and the auxiliary support pipes 5 are vertically connected to the main water inlet pipe 4 .

[0037] The blocking connection strip 6 is fixedly connected to the end of the secondary support tube 5 away from the main water inlet pipe 4 , and the blocking connection strip 6 blocks the end of the secondary support tube 5 .

[0038] In this embodiment, a connecting pipe interface 7 is installed on the main water inlet pipe 4, and the connecting pipe interface 7 is connected to the fire water pipe. The secondary support pipe 5 is provided with a plurality of cooling water holes 8 at equal intervals along the vertical diameter direction, and the cooling water holes 8 are used to spray water to cool the outside of the battery.

[0039] When extinguishing a fire, the fire water pipe is connected to the connecting pipe interface 7. After turning on the fire water switch, the fire water is sprayed out from the cooling water hole 8 on the auxiliary support pipe 5. The fire water is sprayed vertically upward and on the outer surface of the new energy vehicle battery chassis, which can extinguish the fire on the surface of the new energy vehicle battery chassis.

[0040] In addition, the main water inlet pipe 4 or the auxiliary support pipe 5 is connected to the puncture head 2 through a pipeline. When the puncture head 2 punctures into the interior of the new energy vehicle battery chassis, fire water is sprayed out from the puncture head 2 to spray water inside the new energy vehicle battery chassis to extinguish the fire.

[0041] In order to facilitate pushing the pipe support frame under the new energy vehicle battery chassis, a mounting plate 9 is fixedly arranged between two adjacent auxiliary support pipes 5, a universal wheel 10 is fixedly installed on the bottom surface of the mounting plate 9, and two connecting frames 11 are symmetrically installed on the main water inlet pipe 4, and a hand push frame 12 is detachably installed on the two connecting frames 11. On-site operators can use the hand push frame 12 to push the pipe support frame under the new energy vehicle battery chassis.

[0042] The connecting frame 11 and the hand push frame 12 can be detachably connected by plugging, and when the hand push frame 12 is not needed, the hand push frame 12 can be disassembled for convenient use. It should be noted that the detachable connection between the connecting frame 11 and the hand push frame 12 includes but is not limited to plugging.

[0043] Furthermore, the top end of the plugging connecting strip 6 is inclined and is used to guide the pipeline support frame to move below the new energy vehicle battery.

[0044] Specifically, the top end of the sealing connection strip 6 is inclined, and the inclined surface formed by the sealing connection strip 6 can guide the pipeline support frame to enter under the battery chassis of the new energy vehicle without colliding with the side wall of the vehicle, thereby playing a certain protective role.

[0045] Furthermore, the lifting member 1 has a driving joint 13 , on which a connecting pipe is detachably provided, and one end of the connecting pipe away from the driving joint 13 is connected to a hydraulic driving member (not shown).

[0046] Specifically, the lifting member 1 and the hydraulic driving member are designed separately, and after being combined, they form a hydraulic cylinder structure. The hydraulic driving member is used to drive the lifting member 1 to lift, and then cooperate with the puncture head 2 to puncture the battery chassis of the new energy vehicle, thereby facilitating water spraying to extinguish the fire inside the battery bottom plate of the new energy vehicle.

[0047] Furthermore, the end of the piercing head 2 is configured to be conical, and the conical end of the piercing head 2 is located away from the end of the lifting member 1.

[0048] Specifically, the water spray hole 3 is located at the puncture head 2 close to the conical end, and the water outlet direction of the water spray hole 3 is toward the puncture head 2 located at the conical end.

[0049] In this embodiment, under the lifting action of the lifting member 1, the conical end of the piercing head 2 pierces the new energy vehicle battery chassis and enters its interior, and then the fire water is sprayed out from the water spray hole 3 to spray water inside the new energy vehicle battery chassis to extinguish the fire.

[0050] Compared with the prior art, the present invention has at least the following beneficial effects:

[0051] The present invention can puncture the battery pack when a fire occurs in the new energy vehicle battery. At the same time, the new energy vehicle battery can be sprayed with fire water for cooling, which can effectively solve the problem that a fire occurs inside the new energy vehicle battery and cannot be directly extinguished, and effectively ensures the safety of new energy vehicle battery fire handling.

[0052] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
