In the above structure, since the switch valve in the cavity is capable of connecting or disconnecting the first port and the second port, when the switch valve connects the first port and the second port, the sampler can be extended into the hopper by moving relative to the blocking assembly along the first direction to sample material in the hopper. After the sampler is retracted into the cavity to complete sampling, the switch valve disconnects the first port and the second port. During the above process, since the blocking assembly maintains its blockage on the second port, outside air and impurities are unlikely to enter the hopper through the second port.

[0026] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0027] Unless otherwise defined, all technical and scientific terms used in this application have the same meanings as commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first" and "second" in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order or a primary-secondary relationship.

[0028] References to "embodiments" in this application mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments.

[0029] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connected," and "attached" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0030] The term "and / or" in this application simply describes an association between related objects, indicating that three possible relationships exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this application generally indicates that the related objects are in an "or" relationship.

[0031] In the embodiments of this application, the same reference numerals represent the same components, and for the sake of brevity, detailed descriptions of the same components in different embodiments are omitted. It should be understood that the thickness, length, width, and other dimensions of the various components in the embodiments of this application, as well as the overall thickness, length, width, and other dimensions of the integrated device shown in the drawings are merely illustrative and should not constitute any limitation on this application.

[0032] In the embodiments of this application, "parallel" includes not only absolute parallelism but also approximately parallelism as commonly understood in engineering practice. Similarly, "perpendicular" also includes not only absolute perpendicularity but also approximately perpendicularity as commonly understood in engineering practice. For example, if the angle between two directions is 85°-9°, they are considered perpendicular; if the angle between two directions is 5°-5°, they are considered parallel.

[0033] The term "plurality" used in this application refers to two or more (including two).

[0034] Currently, market developments indicate that battery devices are becoming increasingly widely used. They are not only used in energy storage systems such as hydropower, thermal power, wind power, and solar power plants, but are also widely used in sampling devices such as energy storage containers and energy storage cabinets. As the application of battery devices continues to expand, the demand for their reliability is also increasing.

[0035] The production of active materials for battery devices typically requires powdered materials, which are typically transported and transferred in a closed environment during the production process. However, during this material transfer process, sampling is often necessary to assess the material's condition and quality. Current sampling devices often disrupt the closed transport state of the material, allowing air and impurities to enter the material, impacting its quality.

[0036] To improve the quality of materials, some embodiments of the present application provide a sampling device, comprising a housing, a switch valve, a blocking assembly, and a sampler. The housing forms a cavity, the housing having a first port and a second port disposed opposite each other along a first direction and communicating with the cavity, the first port being configured to communicate with a hopper, the switch valve disposed in the cavity being capable of connecting or disconnecting the first port and the second port, the blocking assembly blocking the second port, and the sampler being movably connected to the blocking assembly along the first direction. In the above structure, since the switch valve in the cavity is capable of connecting or disconnecting the first port and the second port, when the switch valve connects the first port and the second port, the sampler can be extended into the hopper by moving relative to the blocking assembly along the first direction to sample the material in the hopper. After the sampler retracts into the cavity to complete sampling, the switch valve disconnects the first port and the second port. During the above process, since the blocking assembly maintains its blockage on the second port, outside air and impurities are less likely to enter the hopper through the second port. This makes it difficult for the sampling device to mix outside air and impurities with the material in the hopper, minimizing the impact on the material and facilitating the improvement of the material quality.

[0037] The sampling device disclosed in the embodiment of the present application can be used for, but is not limited to, sampling powdered active material materials. It can also be used for sampling powdered intermediates such as fuel, soap powder, and inorganic salts. It can also be used for sampling liquid or gaseous materials. It can reduce the possibility of the material being mixed with external air and impurities, has less impact on the material, and is conducive to improving the quality of the material.

[0038] Some embodiments of the present application provide a sampling device, referring to Figure 1 The sampling device includes a shell 1, a switch valve 2, a blocking assembly 3 and a sampler 4. The shell 1 forms a cavity 11. The shell 1 is provided with a first port 12 and a second port 13 which are arranged opposite to each other along a first direction X and communicate with the cavity 11. The first port 12 is used to communicate with the hopper 10; the switch valve 2 is arranged in the cavity 11, and the switch valve 2 can connect or disconnect the first port 12 and the second port 13; the blocking assembly 3 blocks the second port 13; the sampler 4 is movably connected to the blocking assembly 3 along the first direction X.

[0039] The housing 1 may be the outer shell structure of the sampling device, which is not only used to enclose the cavity 11 of the sampling device, but also used to connect other components of the sampling device and can support other components in the sampling device.

[0040] The cavity 11 may be a cavity structure in the sampling device, which may be used as a cavity for sampling, and may not only contain the sampled material but also contain the sampler 4 used for sampling.

[0041] The first port 12 and the second port 13 may be opening structures formed on the housing 1 , and the two are arranged opposite to each other along the first direction X. The first port 12 is in communication with the hopper 10 , which may mean that the first port 12 can be in communication with the inner cavity of the hopper 10 , so that the sampler 4 can extend from the cavity 11 into the hopper 10 through the first port 12 to sample the material in the hopper 10 .

[0042] The switch valve 2 may be a valve body structure capable of connecting or disconnecting its two sides. By disposing the switch valve 2 in the cavity 11, the switch valve 2 can connect or disconnect the first port 12 and the second port 13. When the switch valve 2 connects the first port 12 and the second port 13, the portion of the cavity 11 between the switch valve 2 and the second port 13 can be connected to the first port 12 through the switch valve 2, facilitating the sampler 4 to take material outside the first port 12 into the cavity 11 between the switch valve 2 and the second port 13. When the switch valve 2 disconnects the first port 12 and the second port 13, the portion of the cavity 11 between the switch valve 2 and the second port 13 can be disconnected from the first port 12, making it difficult for air and impurities in the cavity 11 between the switch valve 2 and the second port 13 to enter the material outside the first port 12 through the first port 12, thereby minimizing the impact on the material.

[0043] The sealing assembly 3 can be a group of components used to seal the second port 13. By sealing the second port 13, it reduces the possibility of external air and impurities entering the cavity 11 through the second port 13, thereby reducing the possibility of air and impurities mixing into the material in the hopper 10 through the first port 12.

[0044] The sampler 4 can be a device for sampling materials. For example, it can be a spoon-shaped structure, a dropper-shaped structure, or a gas collection bag-shaped structure, so that the sampler 4 can collect samples of powdered materials, liquid materials, gas materials, etc.

[0045] Since the first port 12 and the second port 13 are arranged relative to each other along the first direction X, the sampler 4 is movably connected to the blocking assembly 3 along the first direction X, so that at least a portion of the sampler 4 can move along the first direction X on the side of the blocking assembly 3 close to the first port 12, and can extend from the first port 12 to the hopper 10, so as to complete the sampling from the hopper 10.

[0046] In the above structure, since the switch valve 2 in the cavity 11 can connect or disconnect the first port 12 and the second port 13, when the switch valve 2 connects the first port 12 and the second port 13, the sampler 4 can extend into the hopper 10 by moving relative to the blocking assembly 3 along the first direction X to sample the material in the hopper 10. After the sampler 4 retracts into the cavity 11 to complete the sampling, the switch valve 2 disconnects the first port 12 and the second port 13. During the above process, since the blocking assembly 3 maintains the blockage of the second port 13, it is difficult for outside air and impurities to enter the hopper 10 through the second port 13. Therefore, the sampling device is unlikely to mix the material in the hopper 10 with outside air and impurities, which has a smaller impact on the material and is conducive to improving the quality of the material.

[0047] In some embodiments, the sealing assembly 3 includes a first sealing member 31, which is connected to the second port 13. The first sealing member 31 is provided with a first through hole 311 extending along the first direction X. The sampler 4 slides sealingly through the first through hole 311, and at least part of the sampler 4 extends into the cavity 11.

[0048] The first blocking member 31 may be a component of the blocking assembly 3 for sealing the second port 13. By sealingly connecting the first blocking member 31 to the second port 13, it is difficult for external air and impurities to enter the cavity 11 through the second port 13.

[0049] The first through hole 311 can be a hole-like structure provided on the first sealing member 31, which passes through the first sealing member 31 along the first direction X, so that at least part of the sampler 4 passing through the first through hole 311 is located in the cavity 11, and the other part is located outside the cavity 11, so that the operator can operate the sampler 4 from outside the cavity 11.

[0050] By sealingly sliding the sampler 4 through the first through hole 311, not only can the part of the sampler 4 that passes through the first through hole 311 seal the first through hole 311, thereby reducing the possibility of external air and impurities entering the cavity 11 through the first through hole 311, but also the sampler 4 can move relative to the shell 1 along the first direction X so that the sampler 4 can extend into the hopper 10 to take samples.

[0051] In some embodiments, the first blocking member 31 is detachably connected to the second port 13 .

[0052] By detachably connecting the first blocking member 31 to the second port 13 , the cavity 11 can be cleaned by removing the first blocking member 31 , which helps to reduce the accumulation of materials in the cavity 11 and the interference of residual materials on sampling.

[0053] For example, the first blocking member 31 may be connected to the second port 13 via a snap-fit ​​structure or may be connected to the second port 13 via a thread, so that the first blocking member 31 is easy to assemble and disassemble at the second port 13 .

[0054] In some embodiments, the blocking assembly 3 further includes a sealing member 32 , which is sealingly connected to the first through hole 311 , and the sampler 4 sealingly slides through the sealing member 32 .

[0055] The seal 32 may be a device for sealing the first through-hole 311 and the sampler 4, thereby reducing the possibility of outside air and impurities entering the cavity 11 through the first through-hole 311. By sealingly connecting the seal 32 to the first through-hole 311 and sliding the sampler 4 through the seal 32, the seal 32 can not only seal the gap between the first through-hole 311 and the inner wall and the sampler 4, but also allow the sampler 4 to slide smoothly.

[0056] Exemplarily, the sealing member 32 may be a sealing ring or a sealing block, and may be made of rubber, silicone, or nylon.

[0057] In some embodiments, the sealing assembly 3 also includes a locking mechanism 33, which includes a cylinder 331, a first cover 332 and a second cover 333. The cylinder 331 is sealed and connected to the first through hole 311 and is arranged along the first direction X. The seal 32 is provided in the cylinder 331. The first cover 332 and the second cover 333 are respectively connected to the two ends of the cylinder 331 and clamp the seal 32. The first cover 332 is located in the cavity 11, and the sampler 4 passes through the first cover 332, the seal 32 and the second cover 333 in sequence.

[0058] The locking mechanism 33 may be a mechanism for locking the seal 32 and increasing the sealing effect of the seal 32 . The locking mechanism 33 is used to reduce the possibility of sealing failure of the seal 32 .

[0059] The barrel 331 may be a structure for arranging the sealing member 32 , which is arranged along the first direction X, so that the sampler 4 passing through the barrel 331 can be arranged along the first direction X.

[0060] The cylinder 331 is sealed and connected to the first through hole 311. The cylinder 331 can pass through the first through hole 311, and the outer peripheral surface of the cylinder 331 is sealed and connected to the inner wall surface of the first through hole 311, so that external air and impurities are not easy to enter the cavity 11 from between the cylinder 331 and the first through hole 311.

[0061] Exemplarily, the outer peripheral surface of the cylinder 331 and the inner wall surface of the first through hole 311 can be welded so that the materials of the cylinder 331 and the first sealing member 31 are melted together, which not only makes the cylinder 331 and the first through hole 311 firmly connected, but also helps to improve the sealing between the outer peripheral surface of the cylinder 331 and the inner wall surface of the first through hole 311.

[0062] The first cover 332 and the second cover 333 are components connected to both ends of the cylinder 331, and are used to clamp the seal 32 provided in the cylinder 331. By disposing the seal 32 in the cylinder 331 and using the first cover 332 and the second cover 333 to clamp the seal 32 from both ends of the cylinder 331, the seal 32 is compressed and shortened in the axial direction and expanded in the radial direction, so that the seal 32 can be more tightly filled between the sampler 4 and the cylinder 331, which is conducive to improving the sealing effect of the seal 32.

[0063] Exemplarily, the first cover 332 is located in the cavity 11, the second cover 333 is located outside the cavity 11, and the sampler 4 passes through the first cover 332, the seal 32 and the second cover 333 in sequence, so that the sampler 4 is sealed and slidably connected to the sealing assembly 3 along the first direction X.

[0064] In some embodiments, the first cover 332 and the second cover 333 are connected to the cylinder 331 by threads.

[0065] The first cover 332 and the second cover 333 are connected to the cylinder 331 by threads, which may mean that both ends of the cylinder 331 are provided with internal threads, part of the first cover 332 is provided with external threads, and part of the second cover 333 is provided with external threads. The part of the first cover 332 provided with external threads is screwed into the cylinder 331 by threads and abuts against the seal 32 located in the cylinder 331, and the part of the second cover 333 provided with external threads is screwed into the cylinder 331 by threads and abuts against the seal 32 located in the cylinder 331. The first cover 332 and the second cover 333 clamp the seal 32, and the clamping force on the seal 32 can be adjusted by screwing, so that the sealing effect of the seal 32 can be adjusted, which is beneficial for the seal 32 to maintain a good seal on the gap between the sampler 4 and the inner wall of the cylinder 331.

[0066] For example, the seal 32 may include graphite packing, which has a good anti-corrosion sealing effect and is conducive to extending the service life of the seal 32 .

[0067] In some embodiments, the sampler 4 includes a sampling portion 41, a connecting rod 42 and a holding portion 43. The connecting rod 42 is connected between the sampling portion 41 and the holding portion 43. The connecting rod 42 slides sealingly through the seal 32. The sampling portion 41 is located in the cavity 11, and the holding portion 43 is located outside the cavity 11.

[0068] The sampling portion 41 may be the portion of the sampler 4 used to hold or accommodate a material sample. It is located at the end of the sampler 4 near the on-off valve 2. The grip portion 43 may be the portion of the sampler 4 held by the operator. It is located outside the cavity 11 and is connected to the sampling portion 41 via a connecting rod 42, allowing the operator to manipulate the sampling portion 41 from outside the cavity 11 through the grip portion 43. The connecting rod 42 may be a rod-shaped component used to connect between the sampling portion 41 and the grip portion 43, and it slides sealingly through the seal 32. The smooth surface of the connecting rod 42 allows it to slide smoothly within the seal 32, which facilitates the operator's manipulation of the sampler 4.

[0069] Exemplarily, the sampling portion 41 may be configured as a spoon-shaped structure, so that the sampling portion 41 can more conveniently obtain powdered materials from the hopper 10 .

[0070] In some embodiments, a first mark is provided on the holding portion 43 and a second mark is provided on the connecting rod 42 .

[0071] The first mark may be a mark provided on the outer peripheral surface of the holding portion 43 , which is used to indicate the orientation of the sampling portion 41 , so that the operator can know the orientation of the sampling portion 41 by observing the position of the first mark during the process of rotating the holding portion 43 .

[0072] The second mark may be a mark provided on the outer peripheral surface of the connecting rod 42, and a plurality of the second marks may be provided at intervals along the first direction X, for indicating the distance that the sampling portion 41 extends out of the first port 12, so that the operator can know the distance that the sampling portion 41 extends out of the first port 12 by observing the positions of the plurality of second marks during the process of pushing the holding portion 43.

[0073] For example, the first mark and the second mark may be scratches formed on the outer surface of the sampler 4 by etching, which is beneficial to extending the service life of the first mark and the second mark.

[0074] In some embodiments, the sampling device also includes a unloading mechanism 6. A unloading port 14 communicating with the cavity 11 is provided on the shell 1. The unloading port 14 is located between the switch valve 2 and the sealing assembly 3 and is arranged downward. The unloading mechanism 6 is connected to the unloading port 14.

[0075] The unloading mechanism 6 may be a mechanism for unloading the sample collected in the sampling device, which enables the sample to be unloaded conveniently, facilitating subsequent analysis and inspection of the sample.

[0076] The discharge port 14 may be an opening for discharging the sample in the cavity 11. By connecting the discharge mechanism 6 to the discharge port 14, the sample in the cavity 11 can enter the discharge mechanism 6, so as to achieve the discharge of the sample.

[0077] By arranging the discharge port 14 between the switch valve 2 and the blocking component 3, when the sampler 4 is retracted into the cavity 11 between the switch valve 2 and the blocking component 3 for sampling, the sample can conveniently enter the discharge mechanism 6 for discharge.

[0078] The discharge port 14 is arranged downward, which may mean that the direction of the discharge port 14 has a vertical downward component. By arranging the discharge port 14 downward and connecting the discharge mechanism 6 to the discharge port 14, the sample in the sampler 4 can fall into the discharge mechanism 6 under the action of gravity, thereby facilitating the discharge of the sample.

[0079] In some embodiments, the unloading mechanism 6 includes a unloading bin 61 and a unloading valve 62 . The inlet of the unloading bin 61 is connected to the unloading port 14 , and the unloading valve 62 is provided at the outlet of the unloading bin 61 .

[0080] The discharge bin 61 may be a structure within the discharge mechanism 6 that temporarily stores sample material to be discharged. The discharge valve 62 may be a valve structure used to control whether the sample material temporarily stored in the discharge bin 61 is discharged. By connecting the inlet of the discharge bin 61 to the discharge port 14 and positioning the discharge valve 62 at the outlet of the discharge bin 61, the sample material in the chamber 11 can fall into the discharge bin 61 and be discharged outward under the control of the discharge valve 62.

[0081] Exemplarily, the unloading bin 61 extends downward in the vertical direction, and the outlet of the unloading bin 61 is arranged downward in the vertical direction, so that when the unloading valve 62 is opened, the sample material in the unloading bin 61 can be smoothly unloaded from the outlet of the unloading bin 61 under the action of gravity, so that the unloading of the sample material is smooth.

[0082] Some embodiments of the present application also provide a material conveying device, such as Figure 2 As shown, the material conveying device includes a hopper 10 and a sampling device 40 provided by any of the above technical solutions. The first port 12 of the shell 1 in the sampling device 40 is connected to the hopper 10, and the sampler 4 in the sampling device 40 can be extended into the hopper 10 to take samples.

[0083] The hopper 10 may be a funnel-shaped container used in the material conveying device to collect or supply materials. The first port 12 of the housing 1 of the sampling device 40 is connected to the hopper 10. This may mean that the hopper 10 has an installation opening, and the first port 12 of the housing 1 of the sampling device 40 is connected to the installation opening, so that the first port 12 is connected to the interior of the hopper 10, allowing the sampler 4 to extend into the hopper 10 to collect material therein, thereby achieving material sampling.

[0084] For example, the first port 12 can be connected to the mounting port by welding, so that the sampling device 40 can be sealed and firmly connected to the hopper 10 .

[0085] Exemplarily, the material conveying device further includes a first conveying pipe 20 and a second conveying pipe 30, one of the first conveying pipe 20 being connected to the inlet of the hopper 10, and the other being connected to the outlet of the hopper 10. The active material used in the battery device can be conveyed through the first conveying pipe 20, the hopper 10, and the second conveying pipe 30.

[0086] Since the material conveying device includes the sampling device provided by the above technical solution, the material in the material conveying device (such as the active material used in the battery device) can be conveniently sampled online without affecting the conveying of the material.

[0087] Some embodiments of the present application further provide a battery device production system, which includes the material conveying device provided by the above technical solution, and the material conveying device is used to convey materials.

[0088] The material conveyed by the material conveying device can be the active material in the battery device. Since the material in the material conveying device provided by the above-mentioned technical solution can be easily sampled, the material therein is easily detected, which helps to improve the quality of the battery devices produced by the battery device production system.

[0089] Some embodiments of the present application provide a sampling device such as Figure 1As shown, the sampling device includes a shell 1, a switch valve 2, a sealing assembly 3, a sampler 4 and a unloading mechanism 6. The shell 1 is provided with a first port 12 and a second port 13 which are arranged opposite to each other along a first direction X and communicate with the cavity 11. The switch valve 2 is arranged in the cavity 11 near the first port 12, and can connect and disconnect the first port 12 and the second port 13. The first sealing member 31 of the sealing assembly 3 is detachably connected to the second port 13, and the cylinder 331 is connected to the first sealing member 31. A sealing member 32 is provided in the cylinder 331. The two ends of the cylinder 331 are respectively connected to the first cover 332 and the second cover 333 and clamp the sealing member 32. The sampler 4 slides through the sealing member 32 in a sealed manner. The sampling part 41 of the sampler 4 can be extended into the hopper 10 from the first port 12 under the control of the operator to collect the material in the hopper 10. The inlet of the discharge bin 61 in the discharge mechanism 6 is connected to the discharge port 14 of the housing 1, and the outlet of the discharge bin 61 is provided with a discharge valve 62. In the above structure, since the switch valve 2 in the cavity 11 can connect or disconnect the first port 12 and the second port 13, when the switch valve 2 connects the first port 12 and the second port 13, the sampler 4 can extend into the hopper 10 by moving relative to the blocking assembly 3 along the first direction X to achieve sampling of the material in the hopper 10. After the sampler 4 retracts into the cavity 11 to complete the sampling, the switch valve 2 disconnects the first port 12 and the second port 13. In the above process, since the blocking assembly 3 maintains the blockage of the second port 13, it is difficult for outside air and impurities to enter the hopper 10 through the second port 13, so that the sampling device is not easy for the material in the hopper 10 to be mixed with outside air and impurities, which has little impact on the material and is conducive to improving the quality of the material.
