Description

Technical Field

[0001] The invention relates to a system for preventing detection equipment from exploding and burning during detection of a large-capacity storage battery, belonging to the technical field of safety protection. Background Art

[0002] With the rapid development of new energy technologies, high-density, large-capacity batteries are not only widely used in new energy vehicles to power vehicles, but are also widely used in the fields of wind power generation and photovoltaic power generation technology to temporarily store electrical energy that cannot be connected to the grid in time during peak power generation.

[0003] With the current level of technology, high-density, large-capacity batteries have not completely solved the problem of combustion and explosion. We often see reports of various safety accidents caused by battery explosions.

[0004] During the experiment and before formal production, various batteries must be strictly tested for various performances, and these batteries are more likely to explode when being tested.

[0005] The testing laboratory used to test batteries has a variety of expensive instruments and equipment, and even the laboratory itself is built with expensive special materials. If a battery explodes during testing and there is no immediate and effective way to deal with it, the entire laboratory and the instruments and equipment can be burned in a very short time, and fire extinguishing measures such as fire extinguishers and watering have almost no effect on the explosion of the battery itself. Because large-capacity batteries weigh hundreds of kilograms or even tons (the weight of wind power, photovoltaic power generation and storage batteries, and batteries used in large equipment), and are connected to the experimental equipment by thick power cords, when an explosion occurs, it is difficult for panicked people to move them out of the laboratory within a few seconds. Summary of the invention

[0006] The technical problem to be solved by the present invention is: how to prevent the detection equipment and laboratory from being burned when detecting large-capacity batteries.

[0007] In view of the above problems, the technical solution proposed by the present invention is: A system for preventing detection equipment from exploding and burning during detection of large-capacity batteries, comprising a box cabinet for placing batteries, a disconnecting device for quickly separating a power line into two parts, and a traction mechanism provided outside a laboratory for dragging the box cabinet out of the laboratory. The power line from the battery to the detection equipment passes through the disconnecting device. When an explosion occurs, the power line is first disconnected by the disconnecting device, and then the box cabinet is dragged out of the laboratory door to an open space by the traction mechanism, so that the batteries in the box cabinet burn on the open space.

[0008] The disconnecting device is arranged at the rear of the box cabinet, and includes a pile body, a clamping piece, an output integrated block with multiple power line blocks, and an input integrated block. The upper end of the pile body has an overlapping cavity that runs through from front to back. The clamping piece is arranged in the overlapping cavity. The power line blocks of the output integrated block are separated by an insulator, and each power line block has an exposed output overlapping surface in the same plane. The power line blocks of the input integrated block are separated by an insulator, and each power line block has an exposed input overlapping surface in the same plane. The rear section of the output integrated block and the front section of the input integrated block are overlapped in the overlapping cavity, and the output integrated block and the input integrated block are compressed by the clamping piece. The output overlapping surfaces of each power line block of the output integrated block are overlapped and connected with the input overlapping surfaces of each power line block of the corresponding input integrated block, and the output integrated block and the input integrated block are respectively connected with the battery and the detection equipment through rubber power lines.

[0009] The clamping member includes a convex rib shaft with ribs on one side, the convex rib shaft is arranged at the lower part of the overlapping cavity of the pile body, and a rotating arm is provided at one end thereof. The output integrated block and the input integrated block are overlapped up and down at the upper part of the convex rib shaft, and the convex rib shaft rotates to compress the output integrated block and the input integrated block through the ribs; the convex rib shaft rotates 30-60° to release the pressure on the output integrated block and the input integrated block, so that the output integrated block can be pulled out.

[0010] A force balancing cushion block is added between the overlapping output integrated block, the input integrated block and the convex ridge shaft, and the force balancing cushion block comprises two upper and lower hard blocks and a rubber layer located between the two hard blocks.

[0011] A socket is provided on the rear wall of the box-type cabinet, and the front end of the output integrated block overlapped with the input integrated block extends into the box-type cabinet through the socket.

[0012] The traction mechanism includes a linkage chain assembly and a winch device. The winch device has a winch and is arranged outside the laboratory door. The linkage chain assembly has a traction chain with one end connected to the box cabinet and the other end wound around the winch. The box cabinet can be pulled out by rotating the winch.

[0013] The linkage chain cable assembly also includes a linkage rod, a linkage chain cable 1 and a traction block fixed to the bottom of the box cabinet. The traction block is provided with a sliding hole that passes through the front and back. The linkage rod is sleeved in the sliding hole and can slide forward and backward. The rear end of the linkage rod is provided with a retaining ring 1 for preventing the linkage rod from continuing to slide forward. A linkage rotating arm is provided on the convex ridge shaft. The linkage rotating arm under working conditions is inclined downward and backward, and the lower end has a notch that opens backward. The front end of the linkage chain cable 1 is connected to the rear end of the linkage rod, and the rear end is hung in the notch at the lower end of the linkage rotating arm and can automatically slide off when the linkage rotating arm is rotated to tilt forward. The traction chain cable is connected to the front end of the linkage rod. When the traction chain cable pulls the linkage rod to slide forward, the linkage rotating arm is first pulled by the linkage chain cable 1 to rotate to the convex ridge shaft to release the pressure on the output integrated block, and then the retaining ring 1 contacts the traction block to apply pulling force to the box cabinet.

[0014] The winch device also has a winch shaft, a drive motor and a human-powered rotating device. The drive motor is connected to the winch shaft through a one-way bearing. The human-powered rotating device includes a rocker arm, a transmission shaft, a transmission belt, a transmission wheel one and a transmission wheel two. One end of the transmission shaft is connected to the rocker arm, and the other end is equipped with the transmission wheel one. The transmission wheel two is installed on the winch shaft through a one-way bearing. One end of the transmission belt is sleeved on the transmission wheel one, and the other end is sleeved on the transmission wheel two.

[0015] Running wheels are arranged at the bottom of the box cabinet, and the bottom surface where the running wheels stop and move is arranged as a ramp which facilitates the box cabinet to slide out of the laboratory door, and the slope of the ramp is based on the standard that the box cabinet can stop.

[0016] An anti-slip device is provided on the ground under the box-type cabinet, which has a stopper, the rear end of the stopper is hingedly installed below the ground through a hinge shaft, the front end of the stopper is lifted upward to form a backward blocking surface, and an anti-sliding block higher than the ground is fixedly provided at the bottom of the box-type cabinet. The anti-sliding block is blocked by the blocking surface of the stopper to prevent the box-type cabinet from sliding outward by itself, and a wedge block is provided between the front end of the stopper and the ground. When an explosion occurs, the wedge block is pulled out to make the stopper rotate around the hinge shaft toward the ground and descend, thereby releasing the obstruction to the anti-sliding block; a linkage chain rope 2 is provided between the wedge block and the linkage rod, and when the linkage chain rope 1 pulls the linkage rotating arm to rotate, it also pulls the wedge block to pull the wedge block outward. Beneficial Effects

[0017] 1. When an explosion occurs, the power cord can be quickly disconnected, and then the box cabinet can be dragged out of the laboratory door to an open space, so that the battery in the box cabinet can burn on the open space. In the case that the explosion of large-capacity batteries cannot be effectively controlled, the laboratory and the equipment in the laboratory can be preserved, and the losses caused by the explosion can be minimized as much as possible; 2.

[0020] The present invention will be further described below in conjunction with embodiments and drawings: Embodiment 1

[0021] like Figure 1 ,2 As shown, the system for preventing the detection equipment from being burned and exploded during the detection of large-capacity batteries includes a box cabinet 1 for placing the battery 7, a disconnecting device 2 for quickly separating the power line 200 into two parts, and a traction mechanism provided outside the laboratory for dragging the box cabinet 1 out of the laboratory, and the power line 200 from the battery 7 to the detection equipment passes through the disconnecting device 2. That is, the box cabinet 1 is placed in the laboratory, and a laboratory door 8 is specially provided to drag the box cabinet out of the open space outside. When an explosion occurs, the power line 200 is firstly quickly disconnected by the disconnecting device 2, and then the box cabinet 1 is dragged out of the laboratory door 8 to the open space by the traction mechanism, so that the battery 7 in the box cabinet 1 burns on the open space. In this way, in the case where the explosion of large-capacity batteries cannot be effectively controlled, the above measures can be adopted to preserve the laboratory and the equipment in the laboratory, and minimize the losses caused by the explosion.

[0022] like Figure 2 As shown in FIG. 7 , the disconnecting device 2 is arranged at the rear of the box cabinet 1, and includes a pile body 21, a pressing member, an output integrated block 22 having multiple power line blocks 201, and an input integrated block 23. The upper end of the pile body 21 has a lap joint cavity 211 that runs through the front and back, and the pressing member is arranged in the lap joint cavity 211. The power line blocks 201 of the output integrated block 22 are separated by an insulator 203, and each power line block 201 has an exposed output lap joint surface 221 in the same plane; the power line blocks 201 of the input integrated block 23 are separated by an insulator 203, and each power line block 201 has an exposed input lap joint surface 222 in the same plane. The rear section of the output integrated block 22 and the front section of the input integrated block 23 are overlapped in the overlap cavity 211, and the output integrated block 22 and the input integrated block 23 are compressed by the pressing member, and the output overlap surfaces 221 of each power line block 201 of the output integrated block 22 are overlapped and connected with the input overlap surfaces 222 of each power line block 201 of the corresponding input integrated block 23, and the output integrated block 22 and the input integrated block 23 are respectively connected with the battery 7 and the detection equipment through the rubber power line 202. In this way, when the pressure applied by the pressing member to the output integrated block 22 and the input integrated block 23 is released, the output integrated block 22 can be pulled out of the overlap cavity 211, so that the box cabinet 1 can be dragged out of the laboratory without being hindered.

[0023] Here, each power line block 201 constituting the output integrated block 22 and each power line block 201 constituting the input integrated block 23 are metal blocks.

[0024] The clamping member includes a convex rib shaft 24 with a convex rib 241 on one side, the convex rib shaft 24 is arranged at the lower part of the overlapping cavity 211 of the pile body 21, and a rotating arm 242 is arranged at one end thereof. The output integrated block 22 and the input integrated block 23 are overlapped up and down at the upper part of the convex rib shaft 24, and the convex rib shaft 24 rotates to press the output integrated block 22 and the input integrated block 23 through the convex rib 241; the convex rib shaft 24 rotates 30-60 degrees to release the pressure on the output integrated block 22 and the input integrated block 23, so that the output integrated block 22 can be pulled out. The convex rib shaft 24 rotates 30-60 degrees to release the pressure on the output integrated block 22 and the input integrated block 23, that is, only the rotating arm 242 needs to be rotated 30-60 degrees to quickly release the pressure on the output integrated block 22 and the input integrated block 23, which is conducive to the rapid separation of the output integrated block 22 and the input integrated block 23 in an emergency.

[0025] A force balancing pad 25 is provided between the overlapping output integrated block 22 and input integrated block 23 and the convex ridge shaft 24, and the force balancing pad 25 includes two upper and lower hard blocks 251 and a rubber layer 252 located between the two hard blocks 251. Since the convex ridge 241 only provides one stress pressure line, when the force balancing pad 25 is used, the entire overlapping part of the output integrated block 22 and the input integrated block 23 can be stressed through the force balancing block. At the same time, the rubber layer 252 can not only play an insulating role, but also use its elasticity to keep the output integrated block 22 and the input integrated block 23 under constant pressure.

[0026] A socket 111 is provided on the rear wall of the box cabinet 1, and the front end of the output integrated block 22 overlapped with the input integrated block 23 extends into the box cabinet 1 through the socket 111. Since the power line blocks 201 constituting the output integrated block 22 and the power line blocks 201 of the input integrated block 23 are all non-combustible metal blocks, such an arrangement can prevent the fire burning in the box cabinet 1 from being introduced into the laboratory along the power line blocks through the rear wall of the box cabinet 1.

[0027] like Figure 8 As shown in FIG. 10 , the traction mechanism includes a linkage chain assembly 3 and a winch device 4. The winch device 4 has a winch 41 and is arranged outside the laboratory door 8. The linkage chain assembly 3 has a traction chain 31 with one end connected to the box cabinet 1 and the other end wound around the winch 41. The box cabinet 1 can be dragged out by rotating the winch 41.

[0028] The linkage chain assembly 3 also includes a linkage rod 32, a linkage chain 33 and a traction block 13 fixed to the bottom of the box cabinet 1. The traction block 13 is provided with a sliding hole 121 that passes through the front and rear. The linkage rod 32 is sleeved in the sliding hole 121 and can slide forward and backward. The rear end of the linkage rod 32 is provided with a retaining ring 321 for preventing the linkage rod 32 from continuing to slide forward. The convex ridge shaft 24 is provided with a linkage arm 243. The linkage arm 243 in the working condition is tilted downward and backward, and the lower end has a notch 2431 that opens backward. The front end of the moving chain rope 33 is connected to the rear end of the linkage rod 32, and the rear end is hung in the notch 2431 at the lower end of the linkage arm 243 and can automatically slip off when the linkage arm 243 rotates to tilt forward. The traction chain rope 31 is connected to the front end of the linkage rod 32. When the traction chain rope 31 pulls the linkage rod 32 to slide forward, the linkage arm 243 is first pulled by the linkage chain rope 33 to rotate to the convex ridge shaft 24 to release the pressure on the output integrated block 22, and then the retaining ring 1 321 contacts the traction block 13 to apply tension to the box cabinet 1. In this way, only one action of pulling the traction chain rope 31 outward can loosen the output integrated block 22 and drag the box cabinet 1, which is very conducive to rapid response in emergency situations where explosions occur.

[0029] A second retaining ring 322 is provided at the front end of the linkage rod 32, and a spring 35 for supporting the linkage rod 32 and keeping the linkage chain 1 33 straight is provided on the outer periphery of the linkage rod 32 between the second retaining ring 322 and the traction block 13.

[0030] The winch device 4 also has a winch shaft 42, a drive motor 43 and a human-powered rotating device. The drive motor 43 is connected to the winch shaft 42 through a one-way bearing 44. The human-powered rotating device includes a rocker arm 46, a transmission shaft 45, a transmission belt 49, a transmission wheel 1 47 and a transmission wheel 2 48. One end of the transmission shaft 45 is connected to the rocker arm 46, and the other end is installed with the transmission wheel 1 47. The transmission wheel 2 is installed on the winch shaft 42 through the one-way bearing 44. One end of the transmission belt 49 is sleeved on the transmission wheel 1 47, and the other end is sleeved on the transmission wheel 2 48. In this way, if the drive motor 43 cannot be started normally due to long-term non-use or when the power is cut off or the power is cut off, the winch 41 can be rotated by manually rotating the rocker arm 46. The provision of the one-way bearing 44 can prevent the motor rotation and the human-powered rotation from interfering with each other. Embodiment 2

[0031] This embodiment is a further improvement on the first embodiment.

[0032] like Figure 1 , 2As shown in Figure 3, a running wheel 11 is provided at the bottom of the box cabinet 1, and the bottom surface where the running wheel 11 stops and moves is provided as a ramp that facilitates the box cabinet 1 to slide out of the laboratory door 8, and the slope of the ramp is based on the standard that the box cabinet 1 can stop. Further, a track 6 is provided for the running of the running wheel 11. Since the box cabinet 1 can weigh hundreds of kilograms to several tons, and the weight of the battery also reaches hundreds of kilograms to several tons, the resistance during dragging will be very large, especially the static friction before dragging is greater. By setting the slope and track as mentioned above, the static friction resistance during starting and the resistance during normal dragging will be greatly reduced. The slope of the ramp is based on the standard that the box cabinet 1 can stop, which means that the box cabinet 1 can stop without any blocking setting. External force must be applied to make it slide, but it does not require too much external force to drag it.

[0033] like Figure 2 , 9 As shown, an anti-slip device 5 is provided on the ground under the box cabinet 1, which has a stopper 51. The rear end of the stopper 51 is hingedly installed below the ground through a hinge shaft 53, and the front end of the stopper 51 is lifted upward to form a backward blocking surface 52. An anti-sliding block 12 higher than the ground is fixedly provided at the bottom of the box cabinet 1. The anti-sliding block 12 is blocked by the blocking surface 52 of the stopper 51 to prevent the box cabinet 1 from sliding outward by itself. A wedge block 54 is provided between the front end of the stopper 51 and the ground. When an explosion occurs, the wedge block 54 is pulled out to make the stopper 51 rotate and descend toward the ground around the hinge shaft 53, thereby releasing the obstruction to the anti-sliding block 12. A linkage chain 2 34 is provided between the wedge block 54 and the linkage rod 32. When the linkage chain 1 33 pulls the linkage rotating arm 243 to rotate, the wedge block 54 is also pulled to pull the wedge block 54 outward. The box cabinet 1 slides outward by itself because after the track 6 with a slope is set, there is a risk that the box cabinet 1 can slide outward when subjected to a small external force or no external force other than gravity, which may cause a safety accident. Therefore, a stopper 51 is set, but before the box cabinet 1 is dragged outward, the stopper 51 must lose its blocking function.

[0034] The above embodiments are only used to more clearly describe the present invention and cannot be regarded as limiting the protection scope of the present invention. Any modifications in equivalent forms should be regarded as falling within the protection scope of the present invention.

When explosion occurs, the wedge block (54) is pulled out to make the stopper (51) rotate and descend toward the ground around the hinge shaft (53), thereby releasing the blocking of the anti-sliding block (12). A second linkage chain (34) is arranged between the wedge block (54) and the linkage rod (32). When the first linkage chain (33) pulls the linkage rotating arm (243) to rotate, the wedge block (54) is also pulled to be pulled out.
