Description

Technical Field

[0001] The present invention relates to the technical field of detection devices, and in particular to a detection device for electric energy storage equipment. Background Art

[0002] It is crucial to test batteries for squeeze, scratches, and explosions to ensure that they do not cause safety accidents due to external mechanical damage or internal failures during energy storage. During long-term use and charging and discharging, batteries may be subjected to physical pressure, vibration, or external collisions, resulting in damage to the battery casing or internal short circuits. Especially in large-scale power storage systems, battery damage may spread rapidly, leading to explosions or fires.

[0003] Extrusion and scratch detection can promptly detect external damage to the battery and prevent these damages from further causing internal battery failures, such as electrolyte leakage, internal short circuit or thermal runaway. Explosion detection focuses on monitoring temperature changes inside the battery and uses temperature sensors to monitor whether the battery is overheating. Excessive temperature may cause gas accumulation inside the battery, which may cause explosion or combustion.

The energy storage equipment to be detected is placed on the storage seat, and the storage seat is arranged on the correction mechanism; the correction mechanism includes a first correction plate, a second correction plate, a first rack plate, a second rack plate, a transmission gear and a limit plate; this structure includes that the device can limit the position of the energy storage equipment through the limit plate in the correction mechanism before the energy storage equipment is detected, and by rotating the transmission gear, the limit plate is separated from the energy storage equipment. At the same time, the position of the energy storage equipment is corrected by the first correction plate and the second correction plate, thereby improving the detection accuracy of the energy storage equipment in the later stage and extending its service life.

[0005] Although the above-mentioned patent documents are used to perform fault detection on energy storage devices during use, they are unable to perform simulated detection on battery-type energy storage devices during actual use, and cannot guarantee that the battery will not explode during the detection process, and cannot effectively relieve the internal pressure.

[0041] Furthermore, the detection component 5 includes a hollow box 511 fixedly connected to the left and right corners of the bottom wall of the shell 1 and the left and right corners of the upper end of the partition 2, and the four corners of the top wall of the shell 1 are rotatably connected to the threaded rod 51, the middle and lower parts of the outer surfaces of the four threaded rods 51 are fixedly connected to the pulley six 512, and the outer surfaces of the two pulleys 512 on the same side are commonly wrapped with a belt four 513, the two threaded rods 51 on the same side respectively penetrate the hollow box 511 in the middle and the inner surface of the guide hole 103 on the same side and are rotatably connected to the bottom wall of the hollow box 511 on the lower side, the upper and lower parts of the outer surfaces of the four threaded rods 51 are commonly threadedly connected to the rectangular box 52, and the left and right sides of the bottom walls of the two rectangular boxes 52 are fixedly connected to the baffle 53, and the outer surfaces of the four threaded rods 51 The upper and lower parts of the surface are both slidably connected with conical teeth 1 54, and the conical teeth 1 54 on the same side are respectively located on the upper sides of the rectangular box 52 on the same side. The left side wall of the inner surface of the rectangular box 52 on the same side and the front part of the left end of the right baffle 53 are both rotatably connected with pulley 4 56. The ends of the two pulleys 4 56 on the same side that are close to each other are fixedly connected with conical teeth 2 55, and the conical teeth 2 55 on the same side are meshed with the conical teeth 1 54 on the same side. The middle part of the right side wall and the middle part of the left side wall of the inner surface of the rectangular box 52 on the same side are both rotatably connected with pulley 5 57, and the outer surfaces of the pulley 5 57 and the pulley 4 56 on the same side are wrapped with belt 3 58 together. Two guide grooves 59 symmetrically distributed on the left and right are opened in the middle of the bottom wall of the rectangular box 52, and an extrusion and scratching assembly 50 is slidably installed in the inner cavity of the rectangular box 52.

[0042] Furthermore, the extrusion and scratch assembly 50 includes two connecting rods 501, the ends of the two connecting rods 501 that are away from each other are fixedly connected to the pulley five 57 on the same side, and the ends of the two connecting rods 501 that are close to each other pass through the baffle 53 on the same side. The ends of the two connecting rods 501 that are close to each other are commonly fixedly connected to a threaded rod two 502, and the outer surface of the threaded rod two 502 is threadedly connected to two hollow threaded blocks 503, and the lower ends of the two hollow threaded blocks 503 are fixedly connected to the limiting blocks 504, and the two limiting blocks 504 are respectively slidably connected to the inner surfaces of the two guide grooves 59, and the lower ends of the two limiting blocks 504 are fixedly connected to the extrusion and scratch blocks 505.

[0043] Furthermore, the four extrusion scratch blocks 505 are all wedge-shaped, the lower end of the transmission rod 43 passes through the inner surface of the mounting opening 104 and is fixedly connected to the threaded rod 51 located at the right front, and the lower end of the connecting rod passes through the outer shell 1 and is fixedly connected to the threaded rod 51 located at the left front.

[0044] Furthermore, two sand outlets 101 are provided on the left side wall and the right side wall of the inner surface of the shell 1, and two fixing holes 102 are provided on the left side wall and the right side wall of the inner surface of the shell 1. The sand outlets 101 on the same side are respectively located on the upper part of the fixing holes 102 on the same side. Guide holes 103 are provided at the four corners of the upper end of the partition 2, and a mounting port 104 is provided on the right side of the front upper end of the shell 1. The middle part of the upper end of the partition 2 and the middle part of the bottom wall of the shell 1 are fixedly connected to an operating table 105. A number of rectangular grooves 106 are provided in a linear array on the upper ends of the two operating tables 105, and a top plate 107 is fixedly connected to the left and right sides of the upper ends of the two operating tables 105.

[0045] First, by opening the two sealed doors 3, the batteries to be tested are placed on the upper sides of the two operating tables 105 respectively, and then the two sealed doors 3 are closed, and then the motor 42 is started, so that the output end of the motor 42 drives the extension rod 44 fixedly connected to it to rotate through the coupling, and when the extension rod 44 rotates, its outer surface and the outer surface of the transmission rod 43 are fixedly connected with pulley 1 45, and the outer surfaces of the two pulleys 1 45 are wound with belt 1 46 together, so when the extension rod 44 is driven, the transmission rod 43 also rotates accordingly, and when the transmission rod 43 rotates, the pulley 2 47 fixed on its outer surface and the outer surface of the pulley 3 48 are wound with belt 2 49 together, so when the pulley 2 47 rotates, it can simultaneously drive the connecting rod at the front left to rotate, and the lower end of the connecting rod and the lower end of the transmission rod 43 are fixedly connected to the threaded rod 1 51 located at the front left and right respectively, so the two threaded rods 1 51 located at the front rotate in the same direction at the same time;

[0046] When the two threaded rods 51 at the front rotate, since the outer surfaces of the two threaded rods 51 on the left and the two threaded rods 51 on the right are connected by the pulley 6 512 and the belt 4 513 on the same side, the four threaded rods 51 can rotate in the same direction at the same time. When the four threaded rods 51 rotate, since the two rectangular boxes 52 are threadedly connected to the outer surfaces of the four threaded rods 51, and the outer surfaces of the rectangular boxes 52 are slidably connected to the inner surface of the shell 1, the two rectangular boxes 52 can move downward at the same time.

[0047] When the rectangular box 52 moves downward, the conical tooth 1 54 on its inner surface is slidably connected to the outer surface of the threaded rod 1 51 on the same side, and the conical tooth 1 54 on the same side is meshed with the conical tooth 2 55 on the same side. At this time, the conical tooth 1 54 on the same side is limited by the meshing position of the conical tooth 2 55 and the position of the bottom wall of the rectangular box 52, so that the conical tooth 1 54 on the same side can rotate with the rotation of the threaded rod 1 51, and can move up and down with the rectangular box 52 on the same side. When the conical tooth 1 54 and the conical tooth 2 55 are meshed for transmission, since the pulley 4 56 on the same side is fixedly connected to the conical tooth 2 55 on the same side, and the outer surfaces of the pulley 4 56 and the pulley 5 57 on the same side are commonly wound with the belt 3 58, the rotational power can be transmitted to the pulley 5 57 through the belt 3 58;

[0048] When the pulley 57 rotates, it can simultaneously drive the connecting rod 501 fixedly connected thereto to rotate, and the two connecting rods 501 on the same side are commonly fixedly connected with the threaded rod 2 502, and the outer surface of the threaded rod 2 502 on the same side is threadedly connected to the two hollow threaded blocks 503 on the same side, and the limit blocks 504 fixedly connected at the lower ends of the two hollow threaded blocks 503 on the same side are respectively slidably connected to the inner surfaces of the guide grooves 59 on the same side. Therefore, under the limiting and guiding action of the guide grooves 59, the limit blocks 504 on the same side drive the extrusion and scratching blocks 505 fixedly connected at their lower ends to move leftward;

[0049] Therefore, through the above operation, the squeezing and scratching block 505 can be moved downward and to the left at the same time. In the process of the squeezing and scratching block 505 moving, after the squeezing and scratching block 505 moves downward a certain distance, the lower end of the squeezing and scratching block 505 contacts the surface of the battery. As can be seen from the above, the four squeezing and scratching blocks 505 are all wedge-shaped. Therefore, when the squeezing and scratching blocks 505 contact the battery surface downward, the squeezing and scratching blocks 505 move to the left, thereby realizing simultaneous pressing and scratch detection on the battery surface.

[0050] During the pressing and scratching test, the top plates 107 fixedly connected to both sides of the upper end of the operating table 105 can prevent the battery from shifting left and right during the test.

[0051] During the initial inspection, the depth of the reduction is shallow. At this time, the surface of the battery only produces deformation, and no explosion occurs. Then the motor 42 is started again for a second inspection. At this time, the depth of the reduction is deepened, and the battery is further squeezed and scratched on the basis of the first inspection. At this time, the surface of the battery may be squeezed and scratched and deformed by the scratch block 505, or even cracked. At this time, observe whether the battery produces an explosion by observing the observation window on the surface of the sealing door 3. If the battery does not produce an explosion, a third inspection is carried out. During the third inspection, the damaged battery is further squeezed and scratched on the basis of the second inspection. At this time, the probability of an explosion is extremely high. If an explosion occurs, the sand-fighting component 6 uses the instantaneous pressure generated by the explosion to push the fire-extinguishing sand inside it to the surface of the battery to reduce the fire. After the battery inside the device burns and exhausts the oxygen inside the device, the battery can be taken out by opening the sealing door 3.

[0052] Embodiment 3: Based on embodiment 2, this embodiment uses the instantaneous pressure generated by the deflagration to push the fire extinguishing sand inside the sand extinguishing assembly 6 to the surface of the battery to reduce the fire.

[0053] For details, see Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 8 、 Figure 9 and Figure 10 A connecting hole 31 is opened at the lower right part of the rear end of the two sealing doors 3. The inner surfaces of the two connecting holes 31 are fixedly connected to threaded rings 32. The inner surfaces of the two threaded rings 32 are threadedly connected to threaded columns 33. The rear ends of the two threaded columns 33 are fixedly connected to discs 34.

[0054] Furthermore, the sand-blowing assembly 6 includes four L-shaped tubes 62, and the inner cavities of the four sand outlets 101 are each provided with a rectangular chamber 61. The four L-shaped tubes 62 are respectively fixedly connected to the inner surfaces of the four fixing holes 102, and the upper ends of the four L-shaped tubes 62 are respectively fixedly connected to a sealing plate 63. The four sealing plates 63 are respectively fitted with the inner surfaces of the rectangular chamber 61 on the same side. The middle parts of the upper ends of the four L-shaped tubes 62 are fixedly connected to a spring 64, the upper ends of the four springs 64 are fixedly connected to an inclined plate 65, the upper ends of the four inclined plates 65 are fixedly connected to a connecting plate 66, the upper ends of the four connecting plates 66 are fixedly connected to a cover plate 67, and the middle parts of the upper ends of the four cover plates 67 are provided with a feed port 68, and the end close to the left cover plate 67 and the right cover plate 67 are fixedly connected to a guard plate 69.

[0055] Furthermore, the four guard plates 69 cooperate with the four sand outlets 101 , and the two inclined plates 65 on the left and the two inclined plates 65 on the right jointly form a V-shape.

[0056] Furthermore, two arc-shaped hollow plates 60 are fixedly connected to the left and right sides of the rear end of the shell 1. The two arc-shaped hollow plates 60 on the same side are respectively connected to the inner cavity of the rectangular chamber 61 on the same side, and the upper part of the inner surface of the four arc-shaped hollow plates 60 is clamped with a sealing cover 601.

[0057] When the battery is pressed and scratched for detection, in the initial detection, the battery surface only deforms and does not produce deflagration. In the second detection, the battery may produce deflagration, but the fire of the deflagration is not large, and the instantaneous pressure generated is not enough to drive the inclined plate 65 to move upward. At this time, it is only necessary to observe the observation window on the outer surface of the sealing door 3 and wait for the battery to burn out the oxygen inside the device. In the process of removing the battery, it is necessary to first rotate the disc 34 so that the disc 34 drives the threaded column 33 to disengage the threaded ring 32. At this time, external air will enter the inner cavity of the shell 1 from the connecting hole 31. If the battery does not re-ignite when air enters the inner cavity of the shell 1, the sealing door 3 can be opened and the battery can be removed. If re-ignition occurs, wait until the battery is completely burned out, open the sealing door 3 and then remove the battery.

[0058] During the third test, the instantaneous pressure generated by the explosion enters the L-shaped tube 62 and pushes the inclined plate 65 on the same side upward. The instantaneous pressure can overcome the elastic force generated by the current deformation of the spring 64 and the friction between the connecting plate 66 and the guard plate 69 on the inner surface of the rectangular chamber 61, thereby pushing the inclined plate 65 upward.

[0059] The four guard plates 69 cooperate with the four sand outlets 101 , so when the tilting plate 65 moves upward, the guard plates 69 on the same side no longer block the sand outlets 101 on the same side;

[0060] As can be seen from the above, the two inclined plates 65 on the left and the two inclined plates 65 on the right together form a V-shape. Therefore, when the inclined plates 65 push the fire extinguishing sand on their upper sides to the sand outlet 101, the fire extinguishing sand will flow into the inner cavity of the housing 1 from the sand outlet 101 and cover the surface of the battery, thereby reducing the fire and also having a pressure relief effect.

[0061] When the fire is reduced, the inclined plate 65 rebounds to its initial state under the action of the spring 64. After the fire is burned out, the above-mentioned operation of removing the battery can be repeated.

[0062] When the fire extinguishing sand covers the surface of the battery, some of the fire extinguishing sand will fall from the rectangular groove 106 to the upper end of the partition 2 and the bottom wall of the shell 1. Subsequently, only the upper end of the partition 2, the bottom wall of the shell 1 and the surfaces of the two operating tables 105 need to be cleaned.

[0063] When fire extinguishing sand needs to be added later, it is only necessary to open the sealing cover 601 on the same side, and then add the fire extinguishing sand from the arc-shaped hollow plate 60 on the same side. The fire extinguishing sand can then fall from the feed port 68 on the same side to the upper side of the inclined plate 65 for storage.

[0064] The above-mentioned clamping method between the middle sealing cover 601 and the upper inner surface of the arc-shaped hollow plate 60 is a conventional setting in the prior art. In this solution, it is only necessary to meet the conventional clamping to prevent it from opening when subjected to the instantaneous pressure generated by the explosion. Therefore, this solution will not elaborate on it in detail.

[0065] It should be noted that the specific installation method of the motor 42, the circuit connection method and the control method used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and modifications are intended to fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
