When the power mechanism pushes the puncture cone 32 to move forwards in the accommodating cavity 311 until the head end of the puncture cone 32 extends out of the accommodating cavity 311, the tip of the puncture cone 32 pierces the outer wall of the connecting seat 2 positioned at the head end of the accommodating cavity 311, meanwhile, one section of the head end of the puncture cone 32 extends into the cavity 221 of the connecting seat 2, and a liquid outlet close to the head end of the puncture cone 32 is positioned in the cavity 221, so that the cavity 221 is communicated with the puncture cavity 321, when the fire-fighting water pipe 4 is communicated with the accommodating cavity 311, water or gas in the fire-fighting water pipe 4 firstly enters the accommodating cavity 311, then enters the puncture cavity 321 through a liquid inlet, then enters the cavity 221 of the connecting seat 2 through a liquid outlet, and finally enters the inner space of the energy storage box through the maintenance opening 11, thereby realizing the cooling of a battery in the energy storage box and achieving the purpose of fire fighting.
In this embodiment, the power mechanism includes a cylinder 33 disposed on one side of the valve body 31, and one end of a telescopic rod 331 of the cylinder 33 extends into the accommodating cavity 311 and abuts against the puncture cone 32. A cylinder 33 is arranged on one side of the valve body 31, a cylinder seat of the cylinder 33 is fixed at the tail end of the valve body 31, one end of a telescopic rod 331 of the cylinder 33 is connected with the cylinder seat, and the other end of the telescopic rod stretches into a containing cavity 311 of the valve body 31. Initially, the puncture valve 3 is located at the tail end of the accommodating cavity 311, one end of the telescopic rod 331 of the air cylinder 33 extending into the accommodating cavity 311 is abutted against the puncture valve 3, at this time, the telescopic rod 331 is in a contracted state, so that when the telescopic rod 331 of the air cylinder 33 extends out, the puncture valve 3 is pushed to move forward in the accommodating cavity 311 until the tip of the head end of the puncture cone 32 extends out of the accommodating cavity 311, the outer wall of the connecting seat 2 located at the head end of the accommodating cavity 311 is pierced, the telescopic rod 331 of the air cylinder 33 is retracted to an original state again, the action of the power mechanism is completed, at this time, the puncture cone 32 stays in place, and a section of the head end of the puncture cone 32 extends into the cavity 221 of the connecting seat 2. The power mechanism is provided with the air cylinder 33, so that the fire fighting device has simple structure and is easy to implement.
After the tip of the puncture cone 32 pierces the side wall of the connecting seat 2, the telescopic rod 331 of the air cylinder 33 needs to retract, because when the telescopic rod 331 of the air cylinder 33 abuts against the puncture valve 3, the liquid inlet at the tail end of the puncture valve 3 is plugged, and after the puncture valve 3 pierces the outer wall of the connecting seat 2, the fire-fighting water pipe 4 needs to pass through the liquid inlet at the tail end of the puncture valve 3, enter the puncture cavity 321 of the puncture valve 3, and then enter the cavity 221 of the connecting seat 2 from the liquid outlet near the head end of the puncture valve 3. Therefore, after the air cylinder 33 provides the force for piercing the outer wall of the connecting seat 2 to the puncture valve 3, the telescopic rod 331 of the air cylinder 33 needs to retract, and no longer abuts against the tail end of the puncture valve 3, so that a passage is formed between the accommodating cavity 311 of the valve body 31 and the puncture cavity 321 of the puncture valve 3.
In this embodiment, the power mechanism further includes a buffer spring 332 sleeved on the telescopic rod 331. The telescopic rod 331 of the air cylinder 33 is sleeved with a buffer spring 332, and when the telescopic rod 331 of the air cylinder 33 is in a contracted state, the buffer spring 332 is in a natural extension state; when the telescopic rod 331 of the air cylinder 33 is extended, the buffer spring 332 is stretched; when the telescopic rod 331 of the air cylinder 33 is retracted, the buffer spring 332 is simultaneously contracted to a naturally extended state. The buffer spring 332 is sleeved on the telescopic rod 331 of the air cylinder 33, on one hand, the buffer spring 332 can limit the telescopic rod 331 to prevent the telescopic rod 331 from shifting towards two sides, so that the extending and retracting actions of the telescopic rod 331 are more stable; on the other hand, the buffer spring 332 can buffer when the telescopic rod 331 extends or retracts, so as to prevent the telescopic rod 331 from colliding with the cavity wall of the accommodating cavity 311 of the valve body 31 severely, and the service life of the air cylinder 33 is affected.
In this embodiment, the inner wall of the accommodating cavity 311 is provided with a spring buckle 34 and a groove for accommodating the spring buckle 34, and the spring buckle 34 ejects from the groove after the puncture cone 32 passes, so as to limit the backward movement of the puncture cone 32 in the accommodating cavity 311. Since the telescopic rod 331 of the air cylinder 33 extends to push the tip of the puncture valve 3 to puncture the outer wall of the connecting seat 2, the telescopic rod 331 of the air cylinder 33 is retracted to the original state and is not abutted against the tail end of the puncture valve 3, and the puncture cone 32 needs to stay in place at this time, so that a state that one section of the head end of the puncture cone 32 extends into the cavity 221 of the connecting seat 2 is maintained, and a passage is formed between the accommodating cavity 311 of the valve body 31 and the puncture cavity 321 of the puncture valve 3 and the cavity 221 of the connecting seat 2.
In order to prevent the telescopic rod 331 of the air cylinder 33 from abutting against the tail end of the puncture valve 3, the puncture valve 3 moves towards the tail end of the accommodating cavity 311 under the action of other external forces, so that the liquid outlet close to the head end of the puncture valve 3 is no longer located in the cavity 221 of the connecting seat 2, and the puncture cavity 321 of the puncture valve 3 and the cavity 221 of the connecting seat 2 cannot be communicated, thereby influencing the fire-fighting water pipe 4 to supply water or gas to the interior of the energy storage box. In the present utility model, therefore, the inner wall of the accommodation chamber 311 is provided with the spring catch 34 and the groove accommodating the spring catch 34.
When the telescopic rod 331 of the air cylinder 33 is in a contracted state and the puncture valve 3 is positioned at the tail end of the accommodating cavity 311, the spring buckle 34 is contracted in the groove under the extrusion of the outer wall of the puncture valve 3; when the telescopic rod 331 of the air cylinder 33 extends out to push the puncture valve 3 to move forwards in the accommodating cavity 311, after the tail end of the puncture valve 3 passes through the position of the spring buckle 34, the spring buckle 34 automatically pops out of the groove and abuts against the tail end of the puncture valve 3, so that when the telescopic rod 331 of the air cylinder 33 retracts and does not abut against the tail end of the puncture valve 3 any more, the spring buckle 34 limits the puncture valve 3, the puncture valve 3 is prevented from moving towards the tail end of the accommodating cavity 311 under the action of other external forces, the puncture cavity 321 of the puncture valve 3 cannot be communicated with the cavity 221 of the connecting seat 2, and the fire fighting effect of the fire fighting device on the energy storage box is guaranteed.
Since the telescopic rod 331 of the air cylinder 33 pushes the puncture valve 3 to move forward in the accommodating cavity 311, after the tail end of the puncture valve 3 passes the position of the spring catch 34, the spring catch 34 will pop out of the groove, and then the telescopic rod 331 of the air cylinder 33 is retracted again, so that the spring catch 34 cannot interfere with the telescopic rod 331 of the air cylinder 33, and the telescopic rod 331 of the air cylinder 33 is prevented from being retracted. It is envisioned that: the telescopic rod 331 of the air cylinder 33 extends into the accommodating cavity 311 along the axis of the accommodating cavity 311, and the sectional area of the end part of the telescopic rod 331 is larger than the sectional area of the liquid inlet at the tail end of the puncture valve 3, so that the telescopic rod 331 can push the puncture valve 3 to move forwards in the accommodating cavity 311.
Two spring buckles 34 are oppositely arranged on the inner wall of the accommodating cavity 311, after the two spring buckles 34 are respectively ejected from the two grooves, the two spring buckles are abutted against the position, away from the axle center of the puncture valve 3, of the tail end of the puncture valve 3, and the sum of the sectional area of the end part of the telescopic rod 331 and the sectional area of the two spring buckles 34 is smaller than the area of the plane of the tail end of the puncture valve 3, so that the two spring buckles 34 are respectively ejected from the two grooves and are not on the moving path of the telescopic rod 331 of the air cylinder 33, and therefore the spring buckles 34 are prevented from interfering with the telescopic rod 331 of the air cylinder 33.
In this embodiment, the puncture valve 3 further comprises an inductor 35, and a connecting line 36 connecting the inductor 35 and the cylinder 33. The puncture valve 3 further comprises an inductor 35 and a connecting line 36, the connecting line 36 connecting the inductor 35 with the cylinder 33. When the fire detection mechanism 5 detects thermal runaway of the battery, a signal is transmitted to the control system.
