Description

Technical Field

[0001] The utility model relates to a linkage chain mechanism in a battery explosion and burning prevention detection equipment system, 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 electricity 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 still 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 experimental process and before formal production, various batteries must undergo rigorous testing of various performance characteristics, and these batteries are more likely to explode during testing.

[0005] Battery testing laboratories are equipped with a variety of expensive instruments and equipment, and even the laboratories themselves are constructed of expensive, specialized materials. If a battery explosion occurs during testing and there is no immediate and effective response, the entire laboratory, along with the equipment, can be destroyed in a short period of time. Fire extinguishers and water spraying are virtually ineffective against battery explosions. Because large-capacity batteries (such as those used for wind and photovoltaic power generation) weigh hundreds of kilograms or even tons and are connected to the laboratory equipment by thick power cables, it is difficult for panicked personnel to remove them from the laboratory in the mere seconds it takes to extinguish an explosion. Utility Model Content

[0006] To address the above-mentioned issues, the applicant has developed a system to prevent large-capacity battery explosions and burns during testing (patent protection was applied for on the same date as this application). The system includes a box cabinet for storing batteries and a traction mechanism. When an explosion occurs, the traction mechanism drags the box cabinet out of the laboratory door to an open space, allowing the batteries inside the box cabinet to burn on the open space, thereby preserving the laboratory and experimental equipment and minimizing the losses caused by the explosion of large-capacity batteries. The system involves a linkage chain mechanism, which is required to continuously complete the following tasks within a few seconds when an explosion occurs:

[0007] Disconnect the power cord between the battery and the testing equipment;

[0008] Unlock the anti-slip device at the bottom of the box cabinet;

[0009] Drag the box cabinet out of the laboratory door.

[0010] The technical problem to be solved by the utility model is: to solve the problem of quickly dragging the box cabinet out of the laboratory door in conjunction with the traction mechanism for the system for preventing the large-capacity battery from exploding and burning the detection equipment during detection.

[0011] In view of the above problems, the technical solution proposed by the present invention is:

[0012] A linkage chain mechanism in a battery explosion and burning prevention detection equipment system includes a traction chain, a linkage chain one and a linkage chain two. The front end of the traction chain is connected to the traction mechanism, and the rear end is connected to a box cabinet and is also connected to the front end of the linkage chain one and the front end of the linkage chain two, respectively. The rear end of the linkage chain one hooks the end of the linkage rotating arm and can automatically fall off the linkage rotating arm after the linkage rotating arm is pulled to complete a forward rotation angle. The rear end of the linkage chain two is connected to a wedge block. When the traction chain is subjected to the pulling force of the traction mechanism, the linkage rotating arm and the wedge block are first subjected to the force. After the linkage rotating arm completes the rotation and the wedge block is pulled out, the box cabinet is subjected to the pulling force of the traction chain.

[0013] The linkage chain mechanism also includes a traction block fixed to the bottom of the box cabinet, the traction block is provided with a sliding hole running through the front and back, a linkage rod that can slide back and forth is installed in the sliding hole, and a retaining ring 1 is provided at the rear end of the linkage rod for preventing the linkage rod from continuing to slide forward in the sliding hole. The rear end of the traction chain is connected to the front end of the linkage rod, and the front ends of the linkage chain 1 and the linkage chain 2 are respectively connected to the rear end of the linkage rod. Under normal working conditions, at least the linkage chain 1 is in a tensioned state, and the retaining ring 1 has a set distance interval.

[0014] A retaining ring 2 is provided at the front end of the linkage rod, and a spring for supporting the linkage rod forward so that the linkage chain 1 is kept in a tensioned state is provided on the outer periphery of the linkage rod between the retaining ring 2 and the traction block.

[0015] The first retaining ring and / or the second retaining ring are mounted on the linkage rod through threaded engagement.

[0016] Two connecting plates extending backward are arranged at the rear end of the retaining ring 1, and holes for respectively connecting the linkage chain 1 and the linkage chain 2 are arranged on the two connecting plates.

[0017] Beneficial effect: Only one operation, namely pulling the traction chain forward, solves the problem that conventional means require multiple operations to disconnect the power cord and separate it into two parts, unlock the anti-slip device, and drag the box cabinet out. In an emergency when a fire or explosion occurs, an effective emergency response can be made with simple and quick continuous actions. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention will be further described below with reference to the embodiments and accompanying drawings:

[0023] like Figure 1 As shown, this application relates to: a box-type cabinet 10 housing a battery 11; a disconnecting device 7 for quickly separating a power cord 9 into two parts; an anti-slip device 8 for preventing the box-type cabinet 10 from sliding forward on its own; and a traction mechanism (not shown) located outside the laboratory for towing the box-type cabinet 10 out of the laboratory in the event of an explosion. The disconnecting device 7 includes a linkage arm 711 that rotates a ridged shaft 71. The linkage arm 711 is tilted downward and rearward, and has a rearward-facing notch 7111 at its lower end for a lanyard. Before towing the box-type cabinet 10, the linkage arm 711 only needs to be rotated forward 30-60 degrees to disconnect and separate the power cord 9 into two parts. The specific structure and principles are not described in detail in this application. The anti-slip device 8 is provided because the box-type cabinet 10 is parked on a sloped track to reduce resistance when towing the box-type cabinet 10. However, the box-type cabinet 10 may slide under relatively small external forces, hence the need for the anti-slip device. The anti-slip device has a block 81, the rear end of the block 81 is hingedly installed below the ground through a hinge shaft, the front end of the block 81 is lifted upward to form a backward blocking surface, and the bottom of the box cabinet 10 is fixed with an anti-sliding block 83 that is higher than the ground. The anti-sliding block 83 is blocked by the blocking surface of the block 81 to prevent the box cabinet 10 from sliding outward on its own. A wedge block 82 is set between the front end of the block 81 and the ground. When the explosion occurs, the wedge block 82 is pulled out to make the block 81 rotate and descend toward the ground around the hinge shaft, thereby releasing the blockage of the anti-sliding block 83.

[0024] like Figure 1 、 2As shown, a linkage chain mechanism in a battery explosion and burning prevention detection equipment system includes a traction chain 1, a linkage chain 2 and a linkage chain 2 3. The front end of the traction chain 1 is connected to the traction mechanism, and the rear end is connected to the box cabinet 10 and is also connected to the front end of the linkage chain 2 and the front end of the linkage chain 2 3 respectively. The rear end of the linkage chain 2 is hooked on the end of the linkage rotating arm 711, and can fall off from the linkage rotating arm 711 by itself after pulling the linkage rotating arm 711 to complete a forward rotation angle. The rear end of the linkage chain 2 3 is connected to the wedge block 82. When the traction chain 1 is subjected to the pulling force of the traction mechanism, the linkage rotating arm 711 and the wedge block 82 are first subjected to the force. After the linkage rotating arm 711 completes the rotation and the wedge block 82 is pulled out, the box cabinet 10 is subjected to the pulling force of the traction chain 1. That is, when the battery explodes, the traction mechanism first decompresses the disconnecting device 7 by pulling the traction chain 1 forward, separating the power cord connecting the battery and the detection equipment into two parts, thereby preventing the box cabinet 10 from being dragged away. At the same time, the wedge block 82 is pulled out, and the block 81 sinks, removing the obstruction to the forward sliding of the box cabinet 10, and then the box cabinet 10 is pulled away. In this way, only one operation, namely pulling the traction chain forward, solves the problem of conventional methods requiring multiple operations to disconnect the power cord 9 into two parts, unlock the anti-slip device, and drag the box cabinet out. In the event of an emergency, an effective emergency response can be made with simple, quick, and continuous actions.

[0025] like Figure 2 、 3 As shown, the linkage chain mechanism also includes a traction block 4 fixed to the bottom of the box cabinet 10. The traction block 4 is provided with a sliding hole 41 extending forward and backward. A linkage rod 5 capable of sliding forward and backward is installed in the sliding hole 41. A retaining ring 1 51 is provided at the rear end of the linkage rod 5 to prevent the linkage rod 5 from sliding forward in the sliding hole 41. The rear end of the traction chain 1 is connected to the front end of the linkage rod 5, and the front ends of the linkage chains 1 and 2 are respectively connected to the rear end of the linkage rod 5. Under normal operating conditions, at least the linkage chain 1 is in tension, and the retaining ring 1 is separated by a set distance. Thus, when the retaining ring 1 contacts the traction block 4, the forward sliding of the linkage rod 5 is blocked. Continuing to pull the traction chain 1 forward will apply a forward tension to the box cabinet 10, causing it to slide. At least the linkage chain 2 is in a tension state. Firstly, the rear end of the linkage chain 2 is only hung on the lower end of the linkage rotating arm 711. Being in a tension state can prevent the linkage chain 2 from sliding downward. Secondly, when the traction chain 1 is pulled, the linkage rotating arm 711 can be subjected to tension in the first place.

[0026] A second retaining ring 52 is provided at the front end of the linkage rod 5, and a spring 6 is provided on the outer periphery of the linkage rod 5 between the second retaining ring 52 and the traction block 4 for supporting the linkage rod 5 forward so that the linkage chain 2 remains in a tensioned state.

[0027] The retaining ring 1 51 and / or the retaining ring 2 52 are installed on the linkage rod 5 through threaded engagement, that is, at least one of the retaining ring 1 51 and the retaining ring 2 52 is detachably installed on the linkage rod 5, making it easy to install the linkage rod 5 into the sliding hole 41 of the traction block 4.

[0028] At the rear end of the retaining ring 1 51, two connecting plates 511 extending backward are provided, and holes for connecting the linkage chain 1 2 and the linkage chain 2 3 are provided on the two connecting plates 511. It is convenient for the linkage chain 1 2 and the linkage chain 2 3 to be connected to the linkage rod 5 respectively.

[0029] The above embodiments are only used to more clearly describe the present invention and cannot be regarded as limiting the scope of protection covered by the present invention. Any modifications in equivalent forms should be regarded as falling within the scope of protection covered by the present invention.
