[0038] In order to facilitate the description of the detection device provided by the embodiments of the present application, first, the flow battery involved in the embodiments of the present application is exemplarily described. The first direction F1, the second direction F2 and the third direction F3 are perpendicular to each other.

[0039] Referring to Figure 1 and Figure 2 , Figure 1Fig. 1 shows a structural schematic diagram of a flow battery part provided by some embodiments of the present application, Figure 2 Fig. 1 shows a structural schematic diagram of a flow battery part provided by some embodiments of the present application,

[0040] In this way, by arranging the plurality of conductive parts 2 in the central region of the electrode plate 1, the current can be more evenly distributed, and the problems of local overheating and uneven current density can be reduced.

[0041] Compared with arranging the conductive parts 2 in the edge region, arranging the conductive parts 2 in the central region can provide support to the middle part of the electrode plate 1, and the electrode plate 1 is less likely to deform. In addition, arranging the conductive parts 2 in the central region of the electrode plate 1 helps the current to be more evenly distributed on the surface of the entire electrode plate 1.

[0042] By arranging the gasket 3 between the electrode plate 1 and the current collector 4 along the third direction F3, a plurality of avoiding openings K are arranged on the gasket 3 along the third direction F3, and the plurality of avoiding openings K are used to avoid the plurality of conductive parts 2.

[0043] It can be understood that the plurality of avoiding openings K used to avoid the plurality of conductive parts 2 includes a case where one avoiding opening K avoids one conductive part 2, and a case where one avoiding opening K avoids a plurality of conductive parts 2.

[0044] By arranging the gasket 3, the flow battery can be stably supported, and the risk of the electrode plate 1 being bent or deformed during the operation of the battery can be reduced. In addition, the gasket 3 helps to evenly disperse the pressure applied by the conductive parts 2, and reduces the damage to the electrode plate 1 and the current collector 4 caused by excessive local pressure.

[0045] In this way, the durability of the entire flow battery can be improved, and the service life and reliability of the flow battery can be prolonged.

[0046] In some embodiments of the present application, continuing to refer to Figure 1 With Figure 2 The avoiding openings K penetrate the gasket 3 along the third direction F1, and the first direction F1 and the third direction F3 are perpendicular to each other.

[0047] It should be noted that the avoidance opening K can penetrate through either side of the pad plate 3 along the first direction F1. In this way, compared with the case without the penetration of the pad plate 3, the penetration of the pad plate 3 has lower machining accuracy, and because one side is penetrated, the pad plate 3 can be more easily allowed to be installed in the avoidance opening K, and the overall assembly efficiency of the flow battery is improved.

[0048] In some embodiments of the present application, continuing to refer to Figure 1 to Figure 2 , and in combination with referring to Figure 3 , Figure 3 A top view schematic diagram of the conductive part 2 installed on the electrode plate 1 is shown in some embodiments of the present application. The pad plate 3 has a first side and a second side oppositely arranged along the first direction F1; all the avoidance openings K penetrate through the first side of the pad plate 3; and / or, the avoidance openings K penetrate through one side of the pad plate 3 along the first direction F1, defining a gap in communication with the avoidance openings K; the avoidance openings K have an abutting surface M1 oppositely arranged along the first direction F1 with the gap, the abutting surface M1 abuts with the conductive part 2, and the abutting surface M1 is configured to contact the outer side surface of the conductive part 2.

[0049] In the case of “the pad plate 3 has a first side and a second side oppositely arranged along the first direction F1; all the avoidance openings K penetrate through the first side of the pad plate 3”, all the avoidance openings K penetrate through the same side of the pad plate 3, so that when the pad plate 3 is installed on the electrode plate 1, it can be installed by horizontal insertion along the first direction F1, without the need to be aligned with the electrode plate 1 along the third direction F3 to cover the electrode plate 1. The horizontal insertion installation method simplifies the assembly process, reduces the alignment difficulty during installation, and improves the production efficiency of the flow battery.

[0050] In other embodiments, referring to Figure 4 , Figure 4 A structure schematic diagram of the pad plate 3 is shown in another embodiment of the present application. A part of the plurality of avoidance openings K penetrates through the first side of the pad plate 3, and the other part penetrates through the second side of the pad plate 3.

[0051] In the case of “the avoidance openings K penetrate through one side of the pad plate 3 along the first direction F1, defining a gap in communication with the avoidance openings K; the avoidance openings K have an abutting surface M1 oppositely arranged along the first direction F1 with the gap, the abutting surface M1 abuts with the conductive part 2, and the abutting surface M1 is configured to contact the outer side surface of the conductive part 2”, in this way, the outer side surface of the conductive part 2 contacts the abutting surface M1, and the contact area between the two is large, so that the pad plate 3 is more stably installed on the electrode plate 1. In particular in the present application, the shape of the conductive part 2 is approximately cylindrical, so the shape of the abutting surface M1 is set as an arc-shaped concave surface.

[0052] The above-mentioned "the gasket 3 has a first side and a second side oppositely arranged along the first direction F1; all the avoiding openings K penetrate the first side of the gasket 3" and "the avoiding openings K penetrate one side of the gasket 3 along the first direction F1, and define a gap in communication with the avoiding openings K; the avoiding openings K have an abutting surface M1 oppositely arranged along the first direction F1 with the gap, and the abutting surface M1 abuts with the conductive part 2, and the abutting surface M1 is configured to contact the outer side surface of the conductive part 2" can be combined arbitrarily according to actual conditions.

[0053] In some embodiments of the present application, reference can be made to Figure 1 to Figure 2 , and in combination with reference to Figure 5 , Figure 5 A top view schematic diagram of two gaskets 3 installed on the electrode plate 1 is shown. All the conductive parts 2 arranged at intervals along the first direction F1 are configured as a conductive group; along the second direction F2, all the conductive groups are arranged at intervals, and the avoiding openings K are arranged one by one corresponding to the conductive groups; and / or, the two gaskets 3 are located between the electrode plate 1 and the current collector 4 along the third direction F3, and the two gaskets 3 abut in the first direction F1.

[0054] In the case of "all the conductive parts 2 arranged at intervals along the first direction F1 are configured as a conductive group; along the second direction F2, all the conductive groups are arranged at intervals, and the avoiding openings K are arranged one by one corresponding to the conductive groups", in this way, one avoiding opening K is used to avoid one conductive group, the conductive groups are arranged at intervals along the first direction F1, the number of avoiding openings K to be opened is reduced, and the avoiding openings K only need to be opened along the first direction F1, and the processing technology is simple. Specifically in the present application, the shape of the electrode plate 1 is approximately a cuboid, and the shape of the plurality of conductive parts 2 is approximately a cuboid. The shape of the gasket 3 is also designed to be a cuboid, so that as much as possible contact with the electrode plate 1 can be achieved when the gasket 3 is installed on the electrode plate 1.

[0055] Reference can be continued to be made to Figure 5 , and in combination with reference to Figure 6 , Figure 6 A top view schematic diagram of two gaskets 3 installed on the electrode plate 1 is shown. In the case of "the two gaskets 3 are located between the electrode plate 1 and the current collector 4 along the third direction F3, and the two gaskets 3 abut in the first direction F1", the installation efficiency of installing the gasket 3 on the electrode plate 1 can be further improved.

[0056] In other embodiments, reference can be made to Figure 7 , Figure 7A top view of the gasket 3 installed on the electrode plate 1 is shown. Compared with the installation of one electrode plate 1, the installation of two gaskets 3 on the electrode plate 1, and the abutment of the two gaskets 3, the number of conductive parts 2 that need to be avoided is smaller, and the processing precision of the two gaskets 3 is lower, which is more convenient for installing the gasket 3 on the electrode plate 1.

[0057] The above-mentioned "all conductive parts 2 arranged at intervals along the first direction F1 form a conductive group; along the second direction F3, all conductive groups are arranged at intervals, and the avoidance opening K is arranged one-to-one with the conductive group" and "two gaskets 3 are located between the electrode plate 1 and the current collector 4 along the third direction F3, and the two gaskets 3 abut in the first direction F1" can be arbitrarily combined according to actual conditions.

[0058] The embodiment of the application provides a detection device JC for detecting the gasket 3 in the flow battery in any one of the above-mentioned embodiments. The detection device JC can be referred to Figure 8 , Figure 8 A structure diagram of the detection device JC provided by some embodiments of the application is shown. The gasket 3 is arranged between the electrode plate 1 and the current collector 4 of the flow battery, the flow battery comprises a plurality of conductive parts 2 located between the electrode plate 1 and the current collector 4, the conductive parts 2 connect the electrode plate 1 and the current collector 4, the gasket 3 is provided with a plurality of avoidance openings K, and the plurality of avoidance openings K are used for avoiding the plurality of conductive parts 2.

[0059] The detection device JC comprises a body BA and a convex part D. The body BA is provided with a recess X, the recess X

[0060] The recess X is used for accommodating the gasket 3, the wall surfaces of the recess X opposite to each other abut each other, the recess X has an opening and a first wall surface opposite to the opening, a plurality of convex parts D are arranged on the first wall surface, the plurality of convex parts D are arranged one-to-one with the plurality of avoidance openings K, and the convex part D is used for being in contact with the inner wall of the avoidance opening K.

[0061] In this way, when the size of the gasket 3 needs to be detected, the gasket 3 only needs to be placed in the recess X, and whether the outer surface of the gasket 3 can abut the inner wall of the recess X can be observed. If the gasket 3 cannot be placed in the recess X, or the gasket 3 is placed in the recess X and it can be obviously seen that part of the inner wall of the recess X cannot be in contact with the outer surface of the gasket 3, then the size of the gasket 3 has a problem, and the gasket 3 is unqualified product.

[0062] It can be understood that the current assembly measurement of the gasket plate 3 often takes artificial one-to-one measurement of each size of the gasket plate 3, and compares it with the specified size to judge whether the gasket plate 3 is qualified. However, such measurement is difficult to measure the size of complex arcs, curves, and is also difficult to measure geometric tolerances such as parallelism, perpendicularity and straightness. And in the measurement process, the gasket plate 3 is easy to deform and difficult to accurately measure the size. In addition, it is difficult to measure the size chain through artificial measurement. The size chain is a concept in mechanical design and manufacturing, which refers to a series of interrelated sizes that affect each other during the processing and assembly of parts, and ultimately determine the overall size and shape of the parts. It can be understood that there may be a size that is the maximum size within the tolerance range, and another structure size related to it is the minimum size within the tolerance range. Although the size measured by artificial measurement is within the tolerance range, the structure of the gasket plate 3 produced cannot be accurately installed on the electrode plate 1. And the selection of a part size will affect the size of other parts of the gasket plate 3, which are interrelated.

[0063] In the present application, the structure design of the detection device JC is designed according to the structure of the electrode plate 1. If the gasket plate 3 can be detected by the detection device JC, the gasket plate 3 can be installed in the electrode plate 1, and the gasket plate 3 can be used for subsequent assembly of the flow battery.

[0064] In some embodiments of the present application, continuing to refer to Figure 1 , Figure 2 and Figure 8 , the avoidance openings K are arranged along the first direction F1, and all the avoidance openings K are arranged along the second direction F2. The convex portions D are arranged along the first direction F1, and all the convex portions D are arranged along the second direction F2, and the first direction F1 and the second direction F2 are arranged perpendicular to each other with the opening direction of the recess X.

[0065] It can be understood that the opening direction of the recess is parallel to the third direction. The avoidance openings K are provided with a plurality of conductive portions 2 on the electrode plate 1 to avoid more, and the convex portions D are correspondingly provided with a plurality of avoidance openings K to detect whether the size of the avoidance openings K is qualified.

[0066] In some embodiments of the present application, continuing to refer to Figure 1 , Figure 2 and Figure 8 , the body BA is provided with a revealing portion L, and the revealing portion L penetrates one side of the body BA along the opening direction of the recess X; the revealing portion L extends towards the edge of the body BA in the direction of the recess X, so that the revealing portion L communicates with the recess X.

[0067] By setting the exposed part L, after the base plate 3 is placed in the detection device JC, when the base plate 3 needs to be taken out from the detection device JC, the operator can contact the exposed part L and the base plate 3, and apply force to the base plate 3 to make the base plate 3 and the detection device JC separate.

[0068] In some embodiments of the present application, continuing to refer to Figure 1 、 Figure 2 and Figure 8 , the convex part D is provided with a plurality of convex parts D, all of which are arranged along the first direction F1, and all of which are arranged along the second direction F2. The first direction F1 and the second direction F2 are arranged perpendicularly to the direction in which the recess X is formed. The exposed part L includes a first exposed sub-part L1, which is located on one side of the body BA along the second direction F2. Along the second direction F2, the distance between the two sides of the adjacent two convex parts D close to each other is greater than the size of the first exposed sub-part L1 in the second direction F2.

[0069] Such design is to make the first part B1 not move relative to the first exposed sub-part L1 when the base plate 3 is placed in the detection device JC, further improving the detection efficiency of the detection device JC.

[0070] In some embodiments of the present application, continuing to refer to Figure 1 、 Figure 2 and Figure 8 , the first exposed sub-part L1 includes a first through hole L11, which is located on at least one side of the body BA in the first direction F1, and the first through hole L11 is in communication with the recess X.

[0071] Specifically in the present application, the first exposed sub-part L1 can be designed as a substantially rectangular through hole, and the corresponding first part B1 is also substantially rectangular. The first through hole L11 is designed as a closed design, which can be regarded as a handle, which is convenient for the operator to take, and can also be hung on a hook for convenient storage.

[0072] In some embodiments of the present application, continuing to refer to Figure 1 、 Figure 2 and Figure 8 , the recess X penetrates at least one side of the body BA in the first direction F1, defining a first gap L12 in communication with the recess X; the first exposed sub-part L1 includes the first gap L12.

[0073] The first gap L12 is formed by the recess X penetratingly opening, which is simpler in processing technology and lower in processing precision requirement, and is convenient for processing and production. The setting of the first gap L12 also facilitates the operator to contact the gasket 3 through the exposed part L and apply force to the gasket 3 to make the gasket 3 and the detection device JC disengage. Moreover, since the first gap L12 is formed by the recess X penetratingly opening, the side of the first gap L12 away from the recess X along the first direction F1 is directly connected with the outside, and the operator can directly contact the gasket 3, which is more convenient for applying force to the gasket 3 to make the gasket 3 and the detection device JC disengage.

[0074] In some embodiments of the present application, continuing to refer to Figure 1 , Figure 2 and Figure 8 , the first exposed sub-part L1 is provided with a plurality of first exposed sub-parts L1, and all the first exposed sub-parts L1 are arranged relative to each other along the first direction F1.

[0075] In this way, the operator can hold the part of the gasket 3 exposed in the first direction F1 with both hands and apply force together, which further facilitates the disengagement of the gasket 3 and the detection device JC, and the force application points of the two are in the first direction F1, which is not easy to damage the gasket 3.

[0076] In some embodiments of the present application, continuing to refer to Figure 1 , Figure 2 and Figure 8 , the first exposed sub-part L1 is provided with a plurality of first exposed sub-parts L1, and all the first exposed sub-parts L1 are arranged relative to each other along the first direction F1.

[0077] In this way, the operator can hold the part of the gasket 3 exposed in the first direction F1 with both hands and apply force together, which further facilitates the disengagement of the gasket 3 and the detection device JC, and the force application points of the two are in the first direction F1, which is not easy to damage the gasket 3.

[0078] In some embodiments of the present application, continuing to refer to Figure 1 , Figure 2 and Figure 8 , the recess X penetrates the body BA on at least one side in the second direction F2, and defines a second exposed sub-part L2 connected with the recess X, and the exposed part L includes the second exposed sub-part L2.

[0079] Similarly, the second exposing part L2 is formed by the recess X, and the machining process is simpler, the machining precision requirement is lower, and the machining production is facilitated. The setting of the second exposing part L2 also facilitates the operator to contact the gasket 3 through the exposing part L and apply force to the gasket 3 to make the gasket 3 and the detection device JC separate. Moreover, since the second exposing part L2 is formed by the recess X, the side of the second exposing part L2 away from the recess X in the second direction F2 is directly connected with the outside, and the operator can directly contact the gasket 3, which is more convenient for applying force to the gasket 3 to make the gasket 3 and the detection device JC separate.

[0080] In some embodiments of the present application, continuing to refer to Figure 1 Figure 2 Figure 8 Figure 8 The inner wall of the exposing part L is smooth. In this way, the gasket 3 is not easily damaged by sharp parts when placed in the detection device JC for detection, and the operator is safer when operating.

[0081] In addition, the electrode plate 1 in the flow battery includes an anode electrode plate 1 and a cathode electrode plate 1. Since the functions and matched parts of the cathode and the anode are different, the thicknesses of the anode electrode plate 1 and the cathode electrode plate 1 can be different. It can be understood that if the thicknesses are different, the size of the recess X opened in the second direction F2 can be different to adapt to the cathode electrode plate 1 or the anode electrode plate 1 with different thicknesses.

[0082] Moreover, the detection device JC in the present application adopts a plastic material, and specifically can adopt bakelite phenolic plastic. In this way, the detection device JC is not only light and portable, but also has a solid and reliable structure, and can provide reliable gasket 3 inspection under the premise of saving costs.

[0083] The technical features of the above embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above embodiments are described, but as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present application.

[0084] The above embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be pointed out that for ordinary skilled persons in the art, some modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
