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. 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.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] Example 1, as Figure 1 、 Figure 2 、 Figure 3 and Figure 5As shown in the figure, a detection device for a power energy storage device includes a housing 1. In the middle of the left inner wall surface and the middle of the right inner wall surface of the housing 1, a partition 2 is fixedly connected. At the rear edge of the bottom wall and the rear edge of the top wall of the housing 1, the rear edges of the ends close to each other of the partition 2 are rotatably connected to a sealing door 3. At the front diagonal of the upper right side of the housing 1, a driving component 4 is fixedly installed. A detection component 5 is rotatably installed on the inner surface of the housing 1. By setting the detection component 5, when simulating the detection of the storage battery, the effects of simultaneously simulating pressing downward and scraping the surface of the storage battery can be achieved. And with the assistance of the driving component 4, multi-stage simulation detection can be realized, thereby simulating the deflagration conditions that occur in different stages of the storage battery. And the detection environment is a sealed environment, thus ensuring the safety of personnel when using the device for detection; A sand-scattering component 6 is fixedly installed on the inner surface of the housing 1. By setting the sand-scattering component 6, when the detection component 5 simulates the detection of the storage battery, if the storage battery deflagrates during the detection, the sand-scattering component 6 can use the instantaneous pressure generated by the deflagration to push the fire-extinguishing sand inside it to the surface of the storage battery, reducing the fire intensity during the deflagration of the storage battery and relieving the pressure inside the device, thereby improving the safety during detection.

[0022] During the use of this solution, observation windows can be added to the outer surfaces of the two sealing doors 3. The installation positions can refer to Figure 1 , and the observation windows are made of fireproof and high-temperature resistant materials, and this material is a conventional setting in the prior art, and only needs to meet the requirements of fireproof and high-temperature resistant, so this solution will not elaborate on it in detail.

[0023] Embodiment 2. On the basis of Embodiment 1, for the purpose of simulating squeezing and scraping the surface of the storage battery.

[0024] Specifically, refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 11 、 Figure 12 and Figure 12, the driving component 4 includes a heat dissipation shell 41 fixedly connected to the front diagonal of the upper right side of the housing 1. A motor 42 is fixedly connected to the rear side of the top wall of the heat dissipation shell 41. A transmission rod 43 is rotatably connected to the front side of the middle of the top wall of the heat dissipation shell 41. The output end of the motor 42 is fixedly connected to an extension rod 44 through a coupling. The lower end of the extension rod 44 is rotatably connected to the upper end of the housing 1. A first pulley 45 is fixedly connected to the lower part of the outer surface of the transmission rod 43. A first belt 46 is wound around the outer surfaces of the first pulley 45 and the extension rod 44 together.

A connecting rod is rotatably connected to the front part of the upper left side of the housing 1. A third pulley 48 is fixedly connected to the outer surface of the connecting rod. A second belt 49 is wound around the outer surfaces of the third pulley 48 and the second pulley 47 together.

[0025] Further, the detection component 5 includes hollow boxes 511 fixedly connected to the corners of the left and right sides of the bottom wall of the housing 1 and the corners of the left and right sides of the upper end of the partition 2. Four first threaded rods 51 are rotatably connected to the four corners of the top wall of the housing 1. Belt wheels six 512 are fixedly connected to the middle and lower parts of the outer surfaces of the four first threaded rods 51. A fourth belt 513 is wound around the outer surfaces of the two belt wheels six 512 on the same side together. The two first threaded rods 51 on the same side respectively penetrate through the hollow box 511 in the middle and the inner surface of the guiding hole 103 on the same side and are rotatably connected to the bottom wall of the hollow box 511 on the lower side. Rectangular boxes 52 are commonly threadedly connected to the upper and lower parts of the outer surfaces of the four first threaded rods 51. Baffles 53 are fixedly connected to the left and right sides of the bottom walls of the two rectangular boxes 52. First tapered teeth 54 are slidably connected to the upper and lower parts of the outer surfaces of the four first threaded rods 51. The first tapered teeth 54 on the same side are respectively located above the rectangular box 52 on the same side. A fourth pulley 56 is rotatably connected to 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 baffle 53 on the right side. Second tapered teeth 55 are fixedly connected to the mutually approaching ends of the two fourth pulleys 56 on the same side. The second tapered teeth 55 on the same side mesh with the first tapered teeth 54 on the same side. A fifth pulley 57 is rotatably connected to the middle of the right side wall and the middle of the left side wall of the inner surface of the rectangular box 52 on the same side. A third belt 58 is wound around the outer surfaces of the fifth pulley 57 and the fourth pulley 56 on the same side together. Two guiding grooves 59 distributed symmetrically left and right are formed in the middle of the bottom wall of the rectangular box 52. An extrusion and scraping component 50 is slidably installed in the inner cavity of the rectangular box 52.

[0026] Further, the extrusion and scraping assembly 50 includes two connecting rods 501. One end of each of the two connecting rods 501 away from each other is fixedly connected to the same-side pulley five 57 respectively. One end of each of the two connecting rods 501 close to each other penetrates through the same-side baffle 53. A second threaded rod 502 is fixedly connected to the one ends of the two connecting rods 501 close to each other. Two hollow threaded blocks 503 are threadedly connected to the outer surface of the second threaded rod 502. A limiting block 504 is fixedly connected to the lower end of each of the two hollow threaded blocks 503. The two limiting blocks 504 are respectively slidably connected to the inner surface of the two guiding grooves 59. An extrusion and scraping block 505 is fixedly connected to the lower end of each of the two limiting blocks 504.

[0027] Further, the four extrusion and scraping blocks 505 are all wedge-shaped. The lower end of the transmission rod 43 penetrates through the inner surface of the mounting opening 104 and is fixedly connected to the first threaded rod 51 at the front right side. The lower end of the connecting rod penetrates through the housing 1 and is fixedly connected to the first threaded rod 51 at the front left side.

[0028] Further, two sand outlets 101 are opened on both the left inner wall and the right inner wall of the housing 1. Two fixing holes 102 are opened on both the left inner wall and the right inner wall of the housing 1. The sand outlets 101 on the same side are respectively located above the fixing holes 102 on the same side. Guide holes 103 are opened at the four corners of the upper end of the partition 2. A mounting opening 104 is opened at the front right side of the upper end of the housing 1. An operating table 105 is fixedly connected to the middle of the upper end of the partition 2 and the middle of the bottom wall of the housing 1 respectively. A number of rectangular grooves 106 are linearly arranged on the upper ends of the two operating tables 105. Top plates 107 are fixedly connected to both the left side and the right side of the upper ends of the two operating tables 105.

[0029] First, by opening the two sealing doors 3, the storage batteries to be detected are respectively placed on the upper sides of the two operating tables 105. Then the two sealing doors 3 are closed. Then, by starting the motor 42, the output end of the motor 42 drives the extension rod 44 fixedly connected thereto to rotate through a coupling. When the extension rod 44 rotates, a first pulley 45 is fixedly connected to the outer surface of both the extension rod 44 and the transmission rod 43, and a first belt 46 is wound around the outer surfaces of the two first pulleys 45. Therefore, when the extension rod 44 drives, the transmission rod 43 also rotates accordingly. When the transmission rod 43 rotates, a second pulley 47 fixedly connected to its outer surface and the outer surface of the third pulley 48 are wound with a second belt 49. Therefore, when the second pulley 47 rotates, the connecting rod at the front left side can be driven to rotate simultaneously. The lower ends of the connecting rod and the transmission rod 43 are respectively fixedly connected to the first threaded rods 51 at the front left side and the front right side. Therefore, the two first threaded rods 51 at the front part rotate in the same direction at the same time; 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. 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; 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; 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. 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. During the preliminary detection, the depth of reduction is relatively shallow. At this time, only the surface of the storage battery is deformed, and there is no deflagration. Then, the motor 42 is started again for the secondary detection. At this time, the depth of reduction deepens, and on the basis of the first detection, the storage battery is further squeezed and rubbed. At this time, the surface of the storage battery may be rubbed and deformed by the squeezing and rubbing block 505, and even cracks may occur. At this time, through the observation window on the surface of the sealing door 3, observe whether the battery produces deflagration. If the battery does not produce deflagration, the third detection is carried out. During the third detection, on the basis of the second detection, the damaged storage battery is further squeezed and rubbed. At this time, the probability of deflagration is extremely high. If deflagration occurs, the sand spreading component 6 is prompted to use the instantaneous pressure generated by the deflagration to push the fire extinguishing sand inside it to the surface of the storage battery to reduce the fire. After the storage battery inside the device burns out the oxygen inside the device, the battery can be taken out by opening the sealing door 3 at this time.

[0030] Embodiment 3. On the basis of Embodiment 2, this embodiment aims to realize the purpose of using the instantaneous pressure generated by deflagration to push the fire extinguishing sand inside the sand spreading component 6 to the surface of the storage battery to reduce the fire.

[0031] Specifically, refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 8 、 Figure 9 and Figure 10 . Connecting holes 31 are respectively opened at the lower right side of the rear ends of the two sealing doors 3. Threaded rings 32 are fixedly connected to the inner surfaces of the two connecting holes 31. Threaded columns 33 are threadedly connected to the inner surfaces of the two threaded rings 32. Discs 34 are fixedly connected to the rear ends of the two threaded columns 33.

[0032] Furthermore, the sand spreading component 6 includes four L-shaped tubes 62. Rectangular chambers 61 are respectively opened in the inner cavities of the four sand outlet ports 101. The four L-shaped tubes 62 are respectively fixedly connected to the inner surfaces of the four fixing holes 102. Sealing plates 63 are fixedly connected to the upper ends of the four L-shaped tubes 62. The four sealing plates 63 are respectively in mutual fit with the inner surfaces of the rectangular chambers 61 on the same side. Springs 64 are fixedly connected to the middle parts of the upper ends of the four L-shaped tubes 62. Tilted plates 65 are fixedly connected to the upper ends of the four springs 64. Connecting plates 66 are fixedly connected to the upper ends of the four tilted plates 65. Covers 67 are fixedly connected to the upper ends of the four connecting plates 66. Feeding ports 68 are respectively opened in the middle parts of the upper ends of the four covers 67. Guard plates 69 are fixedly connected to the mutually approaching ends of the left cover 67 and the right cover 67.

[0033] Furthermore, the four guard plates 69 cooperate with the four sand outlet ports 101. The two tilted plates 65 on the left and the two tilted plates 65 on the right together form a V shape.

[0034] Further, two arc-shaped hollow plates 60 are fixedly connected to the left and right sides of the rear end of the outer shell 1. The two arc-shaped hollow plates 60 on the same side communicate with the inner cavity of the rectangular chamber 61 on the same side respectively. Sealing caps 601 are clamped on the upper parts of the inner surfaces of the four arc-shaped hollow plates 60.

[0035] When performing a pressing and rubbing test on the storage battery, during the preliminary test, only deformation occurs on the surface of the storage battery and no deflagration occurs. During the second test, the storage battery may deflagrate, but the fire of the deflagration is not large, and the instantaneous pressure generated is not sufficient to drive the inclined plate 65 to move upward. At this time, only by observing the observation window on the outer surface of the sealing door 3 and waiting for the storage battery to burn out the oxygen inside the device. During the process of taking out the storage battery, it is necessary to first rotate the disc 34 so that the disc 34 drives the threaded column 33 to disengage from the threaded ring 32. At this time, external air will enter the inner cavity of the outer shell 1 from the connection hole 31. If the storage battery does not reignite when the air enters the inner cavity of the outer shell 1, the sealing door 3 can be opened, and then the storage battery can be taken out. If reignition occurs, wait until the storage battery burns out, and then open the sealing door 3 and take out the storage battery; During the third test, the instantaneous pressure generated by the deflagration enters the L-shaped pipe 62 and pushes the inclined plate 65 on the same side upward. At this time, the instantaneous pressure can break through the elastic force generated by the current deformation of the spring 64, as well as the frictional force between the connecting plate 66 and the protective plate 69 on the inner surface of the rectangular chamber 61, so as to push the inclined plate 65 upward; The four protective plates 69 cooperate with the four sand outlets 101. Therefore, during the upward movement of the inclined plate 65, the protective plate 69 on the same side no longer blocks the sand outlet 101 on the same side; 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 plate 65 pushes the fire extinguishing sand above it to the sand outlet 101, the fire extinguishing sand will pour into the inner cavity of the outer shell 1 from the sand outlet 101 and cover the surface of the storage battery, thereby reducing the fire and simultaneously playing a role in pressure relief; When the fire subsides, the inclined plate 65 rebounds to the initial state under the action of the spring 64. After the fire burns out, the operation of taking out the storage battery as described above can be repeated; When the fire extinguishing sand covers the surface of the storage battery, part of the fire extinguishing sand will fall from the rectangular groove 106 to the upper end of the partition plate 2 and the bottom wall of the outer shell 1. Subsequently, only the upper end of the partition plate 2, the bottom wall of the outer shell 1 and the table tops of the two operating platforms 105 need to be cleaned; When adding fire extinguishing sand subsequently, only need to open the sealing cap 601 on the same side, then add the fire extinguishing sand from the arc-shaped hollow plate 60 on the same side, and then the fire extinguishing sand can fall to the upper side of the inclined plate 65 for storage from the feed port 68 on the same side.

[0036] The clamping method of the sealing cover 601 and the upper inner surface of the arc-shaped hollow plate 60 described above is a conventional setting in the prior art. In this solution, only conventional clamping needs to be satisfied to prevent it from opening under the instantaneous pressure generated by deflagration. Therefore, this solution will not elaborate on it in detail.

[0037] It should be particularly noted that the specific installation method, circuit connection method, and control method of the motor 42 adopted in the present invention are all conventional designs, and the present invention will not elaborate on them in detail.
