Detailed Implementation

[0017] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1:

[0019] Please see Figures 1-8As shown, an electrolyte sampling device for a lithium battery production line includes a placement plate 1; a circular plate 2 is rotatably connected to the inner wall of the placement plate 1, and the placement plate 1 is ring-shaped; a set of sampling tubes 4 are provided at the top of the outer wall of the circular plate 2 via a set of sliders 3; a connecting column 5 is fixedly connected to the top of the outer wall of the placement plate 1; a sampling shell 6 is fixedly connected to the top of the outer wall of the connecting column 5 via a first cylinder; a set of sampling tubes 4 are respectively connected to the sampling shell 6 via a set of flexible hoses 7, and all of the flexible hoses 7 are connected to the sampling shell 6; a pump body 8 is fixedly connected to the top of the outer wall of the sampling shell 6, and the pump body 8 is connected to the sampling shell 6; a barrel 9 is fixedly connected to the top of the outer wall of the sampling shell 6 via a fixing block; the output end of the pump body 8 is connected to the barrel 9 via a first pipe 10, and one end of the outer wall of the first pipe 10 is located inside the barrel 9; a circular groove 11 is opened at the top of the outer wall of the placement plate 1. A motor 12 is fixedly connected to the inner wall of the circular groove 11; a rotating shaft 13 is provided at the output end of the motor 12; a set of first toothed grooves 14 are opened on the outer wall of the circular plate 2; a first gear 15 is fixedly connected to the outer wall of the rotating shaft 13, and the first gear 15 meshes with the first toothed grooves 14. By placing the placement plate 1 on a container for storing electrolyte, such as an electrolyte tank, the motor 12 drives the rotating shaft 13 to rotate, and the rotating shaft 13 drives the first gear 15 to rotate. Because the first gear 15 meshes with the set of first toothed grooves 14 on the circular plate 2, the rotation of the first gear 15 drives the circular plate 2 to rotate, and the rotation of the circular plate 2 drives a set of sampling tubes 4 to rotate, thereby changing the sampling area of ​​the sampling tubes 4. This makes the sampling accuracy of this device higher, and can more comprehensively reflect the overall quality status of the electrolyte, making the subsequent electrolyte detection data more accurate.

[0020] The circular plate 2 includes an annular plate 201 and a circular block 202; the outer wall of the circular block 202 is rotatably connected to the inner wall of the annular plate 201; a circular rod 16 is fixedly connected to the top of the outer wall of the circular block 202, and the top of the outer wall of the circular rod 16 is fixedly connected to the top of the inner wall of the connecting column 5; a second bevel gear 17 is fixedly connected to the outer wall of the circular rod 16; a set of sliding grooves 18 are formed on the outer wall of the annular plate 201; the outer walls of a set of sliders 3 are slidably connected to the inner walls of the set of sliding grooves 18; a set of sampling tubes 4 are fixedly connected to the set of sliders 3, and the set of sampling tubes The top and bottom ends of the outer wall of the circular plate 201 are located above and below a set of sliders 3, respectively. A set of first threaded rods 19 are rotatably connected to the top of the outer wall of the annular plate 201 via a set of square blocks. Each set of first threaded rods 19 passes through a set of sliders 3 and is threadedly connected to a set of sliders 3. The sliders 3 are inverted L-shaped. A third bevel gear 20 is fixed to one end of the outer wall of each set of first threaded rods 19, and each set of third bevel gears 20 meshes with a second bevel gear 17. When the circular plate 2 rotates, because the circular plate 2 includes the annular plate 201… When the annular plate 201 on the circular plate 2 rotates, the circular rod 16 on the circular block 202 is fixed to the connecting post 5, and the connecting post 5 is fixed to the placement plate 1. As the annular plate 201 rotates, the second bevel gear 17 on the circular block 202 and the circular rod 16 remains relatively stationary. The rotation of the annular plate 201 drives a set of first threaded rods 19 and third bevel gears 20 to rotate around the center of the circular block 202. Since the set of third bevel gears 20 are all meshed with the second bevel gear 17, when the set of third bevel gears 20 rotates, the second bevel gear 17... The rotation of gear 17 causes the third bevel gear 20 to drive the first threaded rod 19 to rotate. Since a set of first threaded rods 19 are threadedly connected to a set of sliders 3, the rotation of the first threaded rods 19 causes the sliders 3 to move in the slide groove 18, thereby causing the sliders 3 to move the sampling tube 4. This further adjusts the position of the sampling tube 4, which, in conjunction with the rotation of the annular plate 201, increases the sampling range of the sampling tube 4, allowing the sampling tube 4 to sample in different areas, thus further improving the sampling quality and effect of the device.

[0021] A fourth gear 23 is fixedly connected to the top of the outer wall of a set of second threaded rods 22; a set of first racks 24 is fixedly connected to the top of the outer wall of the annular plate 201, and a set of fourth gears 23 meshes with a set of first racks 24 respectively; the first racks 24 are L-shaped and are located above the slider 3 and beside the slide groove 18. When the slider 3 moves in the slide groove 18, the movement of the slider 3 drives the second threaded rods 22 and the fourth gears 23 to move. Since a set of fourth gears 23 meshes with a set of first racks 24 respectively, the movement of the fourth gears 23 is caused by the rotation of the first gear 15, thereby causing the rotation of the first gear 15 to drive the second threaded rods 22 to rotate, thereby adjusting the sampling depth of the sampling tube 4. Thus, this device can change the three-dimensional coordinates of the sampling tube 4 simultaneously through a power source, making the device more intelligent and able to accurately sample electrolyte at multiple locations without manual assistance.

[0022] A filter plate 25 is fixedly connected to the inner wall of the barrel 9; an annular baffle 26 is fixedly connected to the top of the outer wall of the filter plate 25; one end of the first pipe 10 located inside the barrel 9 is located inside the annular baffle 26, and the first pipe 10 is located above the annular baffle 26; a rotating rod 27 is rotatably connected to the center of the top of the outer wall of the barrel 9, and the bottom end of the outer wall of the rotating rod 27 penetrates the top of the outer wall of the barrel 9 and is located inside the barrel 9; a first sprocket 28 is fixedly connected to the top of the outer wall of both the rotating shaft 13 and the rotating rod 27, and a pair of first sprockets 28 are connected by a first chain 29; a set of cleaning rods 30 is provided on the outer wall of the end of the rotating rod 27 located inside the barrel 9, and the cleaning rods 30 are matched with the filter plate 25; a storage shell 32 is rotatably connected to the inner wall of the barrel 9 through a rotating plate 31, and the rotating plate 31 is annular; the top of the outer wall of the storage shell 32 is open, and the storage shell 32 is matched with the filter plate 25. When the sampling tube 4 samples the electrolyte... Afterwards, the electrolyte will enter the sampling shell 6 through the hose 7, and then enter the barrel 9 through the pump body 8 and the first pipe 10, thus falling onto the filter plate 25. Due to the annular baffle 26, the electrolyte is blocked and can only fall into the storage shell 32 from above. As the electrolyte falls into the storage shell 32, it is filtered by the filter plate 25, so that the sampled electrolyte is less likely to contain impurities, making subsequent electrolyte testing more convenient and faster. When the motor 12 drives the rotating shaft 13 to rotate, the rotating shaft 13 and the top of the outer wall of the rotating rod 27 are both fixed with the first sprocket 28, and a pair of first sprockets 28 are connected by the first chain 29. The rotation of the rotating shaft 13 drives the rotating rod 27 to rotate through the first sprockets 28 and the first chain 29, and the rotating rod 27 drives the cleaning rod 30 to rotate, so that impurities are less likely to accumulate and clog the filter plate 25, thus ensuring the filtration environment.

[0023] The sampling tube 4 includes a first circular tube 401 and a second circular tube 402; the first circular tube 401 is fixedly connected to the slider 3; the inner wall of the second circular tube 402 is slidably connected to the outer wall of the first circular tube 401; a connecting block 21 is fixedly connected to the outer wall of the second circular tube 402; a second threaded rod 22 is rotatably connected to the top of the outer wall of the slider 3, and the bottom end of the outer wall of the second threaded rod 22 passes through the slider 3 and the connecting block 21, and the second threaded rod 22 is threadedly connected to the connecting block 21. When the second threaded rod 22 rotates through the sampling tube 4, which includes the first circular tube 401 and the second circular tube 402, the second threaded rod 22... The second threaded rod 22 is threadedly connected to the connecting block 21, so that the rotation of the second threaded rod 22 drives the connecting block 21 to move up and down. The up and down movement of the connecting block 21 drives the second circular tube 402 to move up and down, thereby allowing the sampling depth of the sampling tube 4 to be adjusted. In conjunction with the movement of the slider 3 and the rotation of the circular plate 2, the three-dimensional coordinates of the sampling tube 4 in this device can be adjusted during sampling, thereby further improving the sampling range of the sampling tube 4 and making the sampled electrolyte more reflective of the overall quality of the electrolyte, thus making the subsequent detection data of the electrolyte more accurate.

[0024] The bottom end of the outer wall of the rotating rod 27 penetrates the filter plate 25 and is located inside the storage shell 32; a set of stirring plates 35 are fixedly connected to the outer wall of the end of the rotating rod 27 located inside the storage shell 32; the bottom end of the outer wall of the barrel 9 is open; a discharge pipe 36 is fixedly connected to the bottom end of the outer wall of the storage shell 32, and the discharge pipe 36 is connected to the storage shell 32; a flow meter is installed inside the discharge pipe 36; an electric control valve is installed inside the discharge pipe 36; a detection instrument 37 is slidably placed on the top of the outer wall of the sampling shell 6, and the detection instrument 37 is located below the storage shell 32. The detection instrument 37 is matched with the discharge pipe 36. The rotation of the rotating rod 27 causes the stirring to occur. The rotating plate 35 prevents the electrolyte from settling within the storage shell 32. When testing is required, the electrolyte remains in motion due to the agitation of the plate 35, ensuring optimal electrolyte condition and more accurate, less error-prone data. To test the electrolyte, the electrically controlled valve in the discharge pipe 36 is opened, allowing the electrolyte to flow out. Simultaneously, a flow meter monitors the electrolyte flow. When the flow rate reaches the standard, personnel and instruments can accurately detect this and control the valve to close, preventing electrolyte waste.

[0025] A set of first square grooves 33 are formed on the outer wall of one end of the rotating rod 27 located inside the barrel 9; the outer walls of a set of cleaning rods 30 are slidably connected to the inner walls of the set of first square grooves 33; springs are fixedly connected to the top of the outer walls of each set of cleaning rods 30, and the top of the outer walls of each set of springs are fixedly connected to the top of the inner walls of the set of first square grooves 33; a square baffle 34 is fixedly connected to the top of the outer wall of the cleaning rod 30, and the outer wall of the square baffle 34 is slidably connected to the outer wall of the rotating rod 27. The square baffle 34 matches the first square grooves 33. When the cleaning rod 30 rotates and causes wear, the elastic force of the springs will prevent wear. The cleaning rod 30 can still contact the filter plate 25 under the action of the spring, thus completing the cleaning operation. This increases the service life of the cleaning rod 30 under the action of the spring. Furthermore, a square baffle 34 is fixed to the top of the outer wall of the cleaning rod 30, which blocks the first square groove 33, thus keeping the first square groove 33 in a closed state. This prevents electrolyte from entering the first square groove 33 and avoids electrolyte waste. This increases the service life of the cleaning rod 30 and solves the problem of electrolyte waste caused by the structure of the cleaning rod 30.

[0026] Example 2:

[0027] Please see Figures 6-7As shown, a first rotating rod 38 is rotatably connected to the bottom of the outer wall of the filter plate 25; a second sprocket 39 is fixedly connected to the outer walls of both the first rotating rod 38 and the rotating rod 27, and a pair of second sprockets 39 are connected by a second chain 40; a sixth gear 41 is fixedly connected to the bottom of the outer wall of the first rotating rod 38; a set of sixth tooth grooves 42 are opened on the outer wall of the storage shell 32, and the sixth gear 41 meshes with the sixth tooth grooves 42; a set of sampling detection grooves 43 are provided at the top of the outer wall of the detection instrument 37, and a set of sampling detection... The slots 43 are arranged in a circular array, and each set of sampling and detection slots 43 is matched with the discharge pipe 36. When the rotating rod 27 rotates, since the outer walls of the first rotating rod 38 and the rotating rod 27 are both fixed with second sprockets 39, and a pair of second sprockets 39 are connected by a second chain 40, the rotation of the rotating rod 27 drives the first rotating rod 38 to rotate through the second sprockets 39 and the second chain 40. The rotation of the first rotating rod 38 drives the sixth gear 41 to rotate. Since the outer wall of the storage shell 32 is provided with a set of sixth tooth grooves 42, Furthermore, the sixth gear 41 meshes with the sixth tooth groove 42, causing the rotation of the sixth gear 41 to drive the rotation of the storage shell 32 through a set of sixth tooth grooves 42. The rotation direction of the storage shell 32 is opposite to that of the stirring plate 35. This makes it less likely for the electrolyte to become relatively still when it is being stirred, thus further improving the stirring effect and efficiency. In addition, a set of sampling detection grooves 43 are provided at the top of the outer wall of the detection instrument 37. The set of sampling detection grooves 43 are arranged in a circular array. When the electrolyte needs to be tested, the storage shell 32 drives the discharge pipe 36 to rotate. When the electrolyte flows out of the discharge pipe 36, the discharge position can be adjusted so that the electrolyte can flow into multiple sampling detection grooves 43 for testing. This allows the device to perform multiple tests on the electrolyte simultaneously, thereby improving the detection efficiency of the electrolyte. Multiple simultaneous tests can also make the detection data of the electrolyte more accurate.

[0028] In use, this invention involves placing the placement plate 1 on a container for storing electrolyte, such as an electrolyte tank. A motor 12 drives a rotating shaft 13 to rotate, which in turn drives a first gear 15. Since the first gear 15 meshes with a set of first toothed grooves 14 on the circular plate 2, the rotation of the first gear 15 causes the circular plate 2 to rotate. This rotation of the circular plate 2 then causes a set of sampling tubes 4 to rotate, thus changing the sampling area of ​​the sampling tubes 4. This results in higher sampling accuracy and a more comprehensive reflection of the overall quality of the electrolyte, leading to more accurate subsequent electrolyte testing data. Furthermore, when the circular plate 2 rotates, because it includes an annular plate 201 and a circular block 202, the rotation of the annular plate 201 causes the circular rod 16 on the circular block 202 to remain stationary. The ring plate 201 is connected to the connecting post 5, which is fixed to the placement plate 1. When the ring plate 201 rotates, the second bevel gear 17 on the circular block 202 and the circular rod 16 remains relatively stationary. The rotation of the ring plate 201 drives a set of first threaded rods 19 and third bevel gears 20 to rotate around the center of the circular block 202. Since the set of third bevel gears 20 are all meshed with the second bevel gears 17, when the set of third bevel gears 20 rotates, the second bevel gears 17 rotate, which in turn drives the first threaded rods 19 to rotate. Since the set of first threaded rods 19 are threadedly connected to a set of sliders 3, the rotation of the first threaded rods 19 drives the sliders 3 to move in the groove 18, which in turn drives the sampling tube 4 to move, thus further adjusting the device. The position of the sampling tube 4, in conjunction with the rotation of the annular plate 201, increases the sampling range of the sampling tube 4, allowing it to sample in different areas. This further improves the quality and effectiveness of the sampling. Furthermore, the sampling tube 4, comprising the first circular tube 401 and the second circular tube 402, allows the second threaded rod 22 to rotate. Because the second threaded rod 22 is threadedly connected to the connecting block 21, the rotation of the second threaded rod 22 causes the connecting block 21 to move up and down. This movement of the connecting block 21, in turn, causes the second circular tube 402 to move up and down. This allows the sampling depth of the sampling tube 4 to be adjusted. Combined with the movement of the slider 3 and the rotation of the circular plate 2, the three-dimensional coordinates of the sampling tube 4 during sampling can be adjusted, thus enhancing the sampling tube's efficiency. 4. The improved sampling range allows the sampled electrolyte to better reflect its overall quality, resulting in more accurate subsequent electrolyte testing data. When slider 3 moves within the groove 18, its movement drives the second threaded rod 22 and the fourth gear 23. Since the fourth gear 23 meshes with a set of first racks 24, its movement is caused by the rotation of the first gear 15. This rotation of the first gear 15 then drives the second threaded rod 22, adjusting the sampling depth of the sampling tube 4. This allows the device to simultaneously change the three-dimensional coordinates of the sampling tube 4 using a single power source, making the device more intelligent and enabling precise sampling of electrolyte from multiple locations without manual assistance.After the sampling tube 4 takes a sample of the electrolyte, the electrolyte will enter the sampling shell 6 through the hose 7, and then enter the tank 9 through the pump body 8 and the first pipe 10, thus falling onto the filter plate 25. Due to the annular baffle 26, the electrolyte is blocked and can only fall into the storage shell 32 from above. As the electrolyte falls into the storage shell 32, it is filtered by the filter plate 25, so that the sampled electrolyte is less likely to contain impurities, making subsequent electrolyte testing more convenient and faster. When the motor 12 drives the rotating shaft 13 to rotate, the rotating shaft 13 and the top of the rotating rod 27 are both fixed with the first sprocket 28, and the pair of first sprockets 28 are connected by the first chain 29, so that the rotation of the rotating shaft 13 is controlled by the first sprockets 28. The first chain 29 drives the rotating rod 27 to rotate, which in turn drives the cleaning rod 30 to rotate. This prevents impurities from accumulating and clogging the filter plate 25, ensuring a safe filtration environment. When the cleaning rod 30 wears down due to rotation, the spring force allows it to remain in contact with the filter plate 25, thus completing the cleaning operation. This increases the service life of the cleaning rod 30 under the action of the spring. Furthermore, a square baffle 34 is fixed to the top of the outer wall of the cleaning rod 30, blocking the first square groove 33 and keeping it closed. This prevents electrolyte from entering the first square groove 33 and reduces electrolyte waste. Therefore, the cleaning rod 30 in this device... While increasing the service life, it also solves the problem of electrolyte waste caused by the structure of the cleaning rod 30. Furthermore, the rotation of the rotating rod 27 drives the stirring plate 35 to rotate, thus preventing electrolyte from settling in the storage shell 32. When the electrolyte needs to be tested, the electrolyte remains in motion under the stirring of the stirring plate 35, ensuring the electrolyte reaches its optimal state for testing, resulting in more accurate and less error-prone data. When the rotating rod 27 rotates, because the outer walls of both the first rotating rod 38 and the rotating rod 27 are fixed with second sprockets 39, and the pair of second sprockets 39 are connected by a second chain 40, the rotation of the rotating rod 27 drives the first rotating rod 38 to rotate through the second sprockets 39 and the second chain 40. The rotation of the rotating rod 38 drives the sixth gear 41 to rotate. Since a set of sixth tooth grooves 42 are provided on the outer wall of the storage shell 32, and the sixth gear 41 meshes with the sixth tooth grooves 42, the rotation of the sixth gear 41 drives the storage shell 32 to rotate through the set of sixth tooth grooves 42. The rotation direction of the storage shell 32 is opposite to the rotation direction of the stirring plate 35. Therefore, when the electrolyte is stirred, the opposite rotation directions of the stirring plate 35 and the storage shell 32 prevent the electrolyte from becoming relatively still, thus further improving the stirring effect and efficiency. When the electrolyte needs to be tested, the electrically controlled valve in the discharge pipe 36 is opened, allowing the electrolyte to be discharged through the discharge pipe 36, while the flow meter simultaneously detects the electrolyte flow.When the electrolyte flow rate reaches the standard, personnel and instruments can accurately detect it through the flow meter, thereby controlling the electronic control valve to close, thus preventing electrolyte waste. Furthermore, a set of sampling detection tanks 43 is located at the top of the outer wall of the detection instrument 37, and these tanks are arranged in a circular array. When electrolyte testing is required, the storage shell 32 drives the discharge pipe 36 to rotate, allowing the electrolyte to flow into multiple sampling detection tanks 43 for testing. This enables the device to simultaneously perform multiple tests on the electrolyte, improving testing efficiency and ensuring more accurate data.
