For example, they may refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0025] The battery pack puncturing water gun of the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Combined with attachment Figure 1-5 , the present invention is introduced in detail.

[0027] A battery pack puncturing water gun mainly comprises a base 1, a manual jack, a water hose connector 2 and a puncturing gun head 3.

[0028] The base 1 serves as the support base for the entire water gun and provides a mounting location for other components. It is made of channel steel and has several weight-reducing slots on its side walls to reduce the weight of the entire device.

[0029] The manual jack is fixed inside the base 1 and is used to drive the puncture gun head 3 to perform the puncture action.

[0030] The water hose connector 2 is arranged on the outside of the base 1 and is used to connect to an external water hose.

[0031] The puncture gun head 3 is detachably connected to the top of the manual jack, and the water hose connector 2 is connected to the puncture gun head 3 through a high-temperature resistant water pipe, so that water can be transported from the water hose connector 2 through the high-temperature resistant water pipe to the puncture gun head 3 and sprayed out.

[0032] The manual jack includes a first jack 4 and a second jack 5 arranged side by side within a base 1, and the first jack 4 and the second jack 5 are connected by a universal coupling 6. This design enables the two jacks to work together, and the universal coupling 6 allows a certain angular deviation between the two jacks, improving the flexibility and adaptability of the equipment.

[0033] The first jack 4 and / or the second jack 5 is provided with a telescopic driving part for driving the jack to perform telescopic movement, thereby driving the puncture gun head 3 to perform a puncture action.

[0034] The first jack 4 comprises a fixed base 7, a diamond-shaped telescopic bracket 8, a top mounting plate 9, a screw 10, and a screw sleeve 11. The fixed base 7 is fixed within the base 1, providing stable support for the entire jack. The diamond-shaped telescopic bracket 8 is vertically arranged, with its bottom pivotally connected to the fixed base 7 and its top pivotally connected to the top mounting plate 9. The extension and retraction of the diamond-shaped telescopic bracket 8 enables the lifting and lowering of the jack.

[0035] The upper and lower rods on each side of the diamond-shaped telescopic frame 8 are rotatably connected by screw sleeves 11. Screw rods 10 pass through the two screw sleeves 11 and are threadedly connected thereto. The threads on the inner walls of the two screw sleeves 11 are in opposite directions, while the threads on the outer walls of the screw rods 10 extend from the middle to the ends in opposite directions, respectively matching the inner threads of the two screw sleeves 11. When the screw rods 10 are rotated, due to the opposite inner thread directions of the two screw sleeves 11, the screw sleeves 11 move in opposite directions along the screw rods 10, thereby driving the diamond-shaped telescopic frame 8 to extend and retract.

[0036] The second jack 5 has the same structure as the first jack 4 and the screw 10 between the two is connected by a universal coupling 6, which ensures that the two jacks can work synchronously and improve the stability and accuracy of puncture.

[0037] The first jack 4 is arranged at one end close to the hose connector 2 , and a height indication mark 12 is provided on the top of the first jack 4 to facilitate the operator to accurately grasp the puncture depth of the puncture gun head 3 .

[0038] The puncture gun head 3 is threadedly connected to the top of the second jack 5, which is convenient for disassembly and replacement of puncture gun heads 3 of different specifications to meet different needs. A waterproof and high-temperature resistant silicone pad 13 is also provided on the top of the second jack 5 to prevent water leakage and protect the top of the jack from high temperatures.

[0039] A hose head mounting plate 14 is provided inside the base 1, and a hose connector 2 is fixed to the outside of the hose head mounting plate 14. A water flow indicator 15 is provided inside the hose head mounting plate 14. A high-temperature resistant water pipe is connected to the water flow indicator 15, and the other end is connected to the puncture gun head 3. The water flow indicator 15 can display the size and status of the water flow in real time, making it convenient for operators to confirm the flow of water and ensure the fire extinguishing effect.

[0040] A metal moving wheel 16 is provided at one end of the base 1 close to the second jack 5 to facilitate the movement of the entire water gun device and improve the maneuverability of the device.

[0041] The telescopic driving part is a T-shaped handle 17, which is fixed to one end of the screw of the first jack 4 close to the hose connector 2. The operator can drive the screw to rotate by rotating the T-shaped handle 17, thereby driving the jack to perform telescopic movement.

[0042] The present invention also includes an extended drive wrench 18, which includes an extension rod 19, a drive rod 20, a universal joint coupling 21, and a T-shaped sleeve 22. The drive rod 20 is plugged into the end of the extension rod 19 to form a T-shaped structure, which facilitates the operator's grip and application of torque. The front end of the extension rod 19 is connected to the T-shaped sleeve 22 via the universal joint coupling 21, and the T-shaped sleeve 22 is sleeved and mated with the T-handle 17. When the operating space is limited or greater driving force is required, the operator can use the extended drive wrench 18 to drive the T-handle 17, improving the convenience and efficiency of operation.

[0043] The specific implementation process of a battery pack puncture water gun of the present invention is as follows:

[0044] To address the rapid burning speed and difficulty of firefighting in new energy vehicle battery packs, the present invention utilizes two manual car jacks. Double-tooth, labor-saving car jacks should be preferred to ensure that the lifting center remains vertical during the lifting process. The second jack 5 on the inside is primarily responsible for raising and lowering the puncture gun head 3 and providing power for it. The puncture gun head 3 is used to puncture the battery pack shell and inject water into the interior. A circular water baffle is installed on top of the second jack 5, and a waterproof and high-temperature resistant silicone pad 13 is placed on it to prevent the fire-fighting water from flowing out of the battery pack.

[0045] The outer first jack 4 and the inner second jack 5 are of the same model and height, primarily providing a reference height for the inner second jack 5. Typically placed on the outside of the vehicle, they also serve as a power transfer point, further increasing their working distance. A universal coupling 6 connects the two manual jacks, ensuring efficient power transmission while preventing the first jack 4 from receiving force while the second jack 5 is not, which could lead to difficulty rotating the drive shafts when the two manual jacks are raised and lowered at different heights.

[0046] Two manual jacks are fixed in series within the base 1 to form a single unit. The outermost edge of the base 1 features a 65mm hose connector 2 for connecting the firefighting water. This connector is connected to a hose mounting plate 14 fixed to the interior of the base 1. Inside this mounting plate 14 is a water flow indicator 15. This indicator's main function is to confirm whether the firefighting water has been injected into the battery pack by rotating a dial on the indicator. This prevents muzzle obstruction from being detected and provides a visual indicator for quickly changing the puncture point.

[0047] A high-temperature and pressure-resistant metal hose is coiled and guided into the piercing gun head 3 of the second jack 5 to ensure water supply for firefighting in high-temperature combustion environments. A pair of steel metal wheels 16 are located on the innermost side of the base 1. The bottom of the wheel body is flush with the bottom of the base 1, which is used to push the vehicle forward and reduce ground friction when placed into the vehicle chassis.

[0048] A separate T-shaped extended drive wrench 18 is made, and its head has a universal joint coupling 21, which can increase the safe working distance while completing multi-angle operation. The T-shaped sleeve 22 is connected to the T-shaped handle 17, and the extension rod 19 is rotated through the drive rod 20 to drive the first jack 4 and the second jack 5 to achieve manual control of lifting.

[0049] Technical requirements:

[0050] 1. The overall closed height of the present invention should be controlled within 20 cm, so that it can be effectively placed in the car chassis during operation. The overall unfolded height should be controlled above 50 cm, so that the puncture gun head 3 can be effectively inserted into the chassis battery pack during operation.

[0051] 2. The overall length of the present invention should be greater than one meter to ensure that the puncture gun head 3 can effectively penetrate the depth of the bottom of the battery pack.

[0052] 3. The extended drive wrench 18 of the present invention should be appropriately lengthened without affecting normal operation to provide the necessary safe working distance for operation. At the same time, another water gun operator should implement water shooting cover during operation to further ensure safety.

[0053] The present invention and its embodiments are described above. This description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs structures and embodiments similar to this technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
