Description

Technical Field

[0001] The utility model relates to an anti-slip device in a system for preventing a storage battery from burning and exploding and damaging a detection device, belonging to the technical field of safety protection. Background Art

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

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

[0004] Before various batteries are put into formal production and during the experimental process, various strict performance tests need to be carried out on them. When such batteries are being tested, the possibility of combustion and explosion is even greater.

[0005] The detection laboratories for testing batteries are equipped with various expensive instruments and equipment, and even the laboratories themselves are built with expensive special materials. If a battery catches fire and explodes during testing and there is no immediate and effective treatment method, the entire laboratory together with the instruments and equipment can be burned down within a very short time. Fire extinguishing measures such as using fire extinguishers and watering have almost no effect on the combustion and explosion of the battery itself. Since large-capacity batteries weigh hundreds of kilograms or even several tons (energy storage batteries for wind power generation and photovoltaic power generation), and there are thick power cables connecting them to the experimental equipment, it is very difficult for panicked people to move them out of the laboratory within a short period of several seconds when a combustion and explosion occurs. Content of the Utility Model

[0006] To solve the above problems, the applicant has developed a system for preventing a large-capacity storage battery from burning and exploding and damaging a detection device during testing (patent protection is applied for on the same day as this application). The system includes a box-type cabinet for placing the storage battery and a traction mechanism. When a combustion and explosion occurs, the traction mechanism drags the box-type cabinet out of the laboratory door to an open space, so that the storage battery in the box-type cabinet burns in the open space to protect the laboratory and the experimental equipment and minimize the losses caused by the combustion and explosion of the large-capacity storage battery as much as possible. Since the total weight of the box-type cabinet and the storage battery in this system reaches one ton to several tons, in order to be able to drag it out of the laboratory with a relatively small thrust when a combustion and explosion occurs, the track on which the box-type cabinet is parked in the laboratory is set as a downhill track from the inside to the outside. However, with such a design, in actual application, a relatively small external force may cause the box-type cabinet to slide outwards, which not only affects the normal progress of the detection, but also may endanger the safety of the equipment and personnel.

[0007] The technical problem to be solved by the present invention is: to solve the problem of stable parking of the box cabinet under normal working conditions for the above-mentioned system to prevent the detection equipment from exploding and burning during the detection of large-capacity batteries, and to require that the box cabinet can be quickly unlocked and released when an explosion occurs.

[0008] In view of the above problems, the technical solution proposed by the present invention is:

[0009] The invention relates to an anti-skid device in a system for preventing battery explosion and burning detection equipment, comprising a first stopper, a second stopper, a rotating shaft and a clamping block. The rotating shaft is fixed to the ground under a box cabinet. The rear end of the first stopper is installed on the rotating shaft, and the front end thereof can rotate around the rotating shaft. In the applied state, the front end of the first stopper is lifted upward to form an angle space with the ground. The clamping block is placed in the angle space and can be pulled forward from the angle space. A blocking surface is formed behind the upwardly lifted first stopper. The second stopper is installed on the lower bottom surface of the box cabinet behind the first stopper. When the box cabinet slides forward on its own, the second stopper is blocked by the blocking surface of the first stopper.

[0010] The clamping block is a wedge-shaped block with a front end thickness greater than a rear end thickness.

[0011] The anti-slip device also includes a frame that can be buried in a pit, the frame having a left side plate and a right side plate, a clamping groove between the left side plate and the right side plate that can accommodate a stopper 1, the two ends of the rotating shaft are respectively installed on the left side plate and the right side plate, and the stopper 1 is installed in the clamping groove in cooperation with the rotating shaft.

[0012] The width of the clamping block is greater than the width of the clamping groove.

[0013] The front end of the clamping block is provided with a hole for the chain of the traction mechanism to pass through.

[0014] The first stopper has a longitudinal groove one opening upward for allowing the chain rope of the traction mechanism to pass through, and the second stopper has a longitudinal groove two opening downward for allowing the chain rope of the traction mechanism to pass through. Beneficial Effects

[0015] 1. When the van cabinet slides forward on its own, it can be blocked and cannot continue to slide forward, thereby ensuring the normal progress of the inspection and avoiding damage to equipment and personnel;

[0016] 2. The unblocking operation is simple and can be completed by the traction chain of the traction mechanism when starting the traction. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation manners

[0022] The following further describes the present utility model in conjunction with the embodiments and the drawings: Embodiment 1

[0023] As Figure 1 , 2 shown, an anti-slip device in a system for a battery explosion prevention and burning detection device includes a first stop block 2, a second stop block 3, a rotating shaft 4 and a clamping block 5. The rotating shaft 4 is fixed on the ground under the cabinet 6. The rear end of the first stop block 2 is installed on the rotating shaft 4, and its front end can rotate around the rotating shaft 4. The front end of the first stop block 2 in the application state is lifted upward, forming an included angle space with the ground. The clamping block 5 is placed in the included angle space and can be pulled out forward from the included angle space. A blocking surface 202 is formed behind the lifted first stop block 2. The second stop block 3 is installed on the lower bottom surface of the cabinet 6 behind the first stop block 2. When the cabinet 6 slides forward by itself, its second stop block 3 is blocked by the blocking surface 202 of the first stop block 2, so that the cabinet 6 cannot continue to slide forward, thus ensuring the normal progress of the detection and avoiding damage to the equipment and personnel. When an explosion occurs, first pull out the clamping block 5, and then the front end of the first stop block 2 can be rotated downward to the ground, allowing the second stop block 3 to pass through, and the cabinet 6 is unlocked and released.

[0024] The clamping block 5 is a wedge-shaped block with a thickness at the front end greater than that at the rear end, which is beneficial to the smooth pulling out of the clamping block 5.

[0025] A hole 501 for the cable 7 of the traction mechanism to pass through is provided at the front end of the clamping block 5. That is, the front end of the clamping block 5 is connected to the cable 7, and the clamping block 5 is pulled out by the forwardly pulled cable 7, without the need to provide a separate pulling-out mechanism.

[0026] The first stop block 2 has a longitudinally upward-opening first groove 201 for the cable 7 of the traction mechanism to pass through, and the second stop block 3 has a longitudinally downward-opening second groove 301 for the cable 7 of the traction mechanism to pass through, so as to avoid interference between the anti-slip device and the cable 7 of the traction mechanism. Embodiment 2

[0027] As Figure 3 , 4 shown, the difference from the first embodiment is that the anti-slip device further includes a frame body 1 that can be buried in the pit. The frame body 1 has a left side plate 101 and a right side plate 102. There is a clamping groove 103 between the left side plate 101 and the right side plate 102 that can accommodate the first stopper 2. Both ends of the rotating shaft 4 are installed on the left side plate 101 and the right side plate 102 respectively. The first stopper 2 is installed in cooperation with the rotating shaft 4 in the clamping groove 103. During application, a pit is provided on the bottom surface under the van-type cabinet, and the frame body can be placed in the pit. In this way, the rotating shaft 4 is fixed to the ground under the van-type cabinet 6 through the frame body 1 fixed to the ground under the van-type cabinet 6.

[0028] The width of the clamping block 5 is greater than the width of the clamping groove 103, so that the clamping block 5 straddles the clamping groove 103 and both ends rest on the upper surfaces of the left side plate 101 and the right side plate 102.

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