Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical testing technology, and in particular to an electrode testing fixture and an electrolytic cell device. Background Technology
[0002] Currently, the inspection of electrolytic cells mainly relies on manual operation. Inspectors periodically carry testing tools such as voltmeters to check the voltage status of the electrolytic cell chambers and record the data. To improve inspection efficiency, sometimes the testing equipment is fixed to the electrolytic cell tabs, for example, by welding or alligator clips. However, welding is cumbersome and inconvenient for subsequent disassembly and maintenance; while alligator clips are prone to poor contact, leading to inaccurate data acquisition.
[0003] Currently, the commonly used improvement method in the industry is to use probes to read the voltage of individual cells. Although spring-loaded probes can read the voltage of a single cell relatively accurately, their design suffers from poor stability during long-term fixed use, making it difficult to ensure accurate monitoring over extended periods. Therefore, there is an urgent need for a test fixture that can stably assemble multiple probes to read the voltage of multiple cells, thereby improving the accuracy and efficiency of inspections. Utility Model Content
[0004] One objective of this invention is to provide an electrode testing fixture and an electrolytic cell device, which aims to optimize the assembly effect of the inspection fixture.
[0005] To achieve the above objectives, the present invention provides an electrode testing fixture, which includes a support, a first clamp and a second clamp connected to the support, and a plurality of probes assembled between the first clamp and the second clamp. Specifically, the support includes a frame, a first arm and a second arm. The frame is used to connect to the electrical device under test. The first arm and the second arm are respectively connected to the frame. The first arm, the second arm and the frame form a clamp groove. The first clamp and the second clamp are stacked together, and their opposite ends are placed in the clamp groove. A plurality of probes are inserted between the first clamp and the second clamp.
[0006] In some embodiments of this application, a first positioning groove is formed on the side of the first clamping plate facing the second clamping plate, and a plurality of probes are respectively assembled in the first positioning groove.
[0007] In some embodiments of this application, a plurality of second positioning grooves are provided on the side of the first clamping plate away from the second clamping plate, and the spacing between adjacent first positioning grooves is different from the spacing between adjacent second positioning grooves.
[0008] In some embodiments of this application, the first positioning groove is a V-shaped groove or an arc groove, and adjacent first positioning grooves are connected to each other.
[0009] In some embodiments of this application, a first through groove is provided on the first clamping plate, a second through groove is provided on the second clamping plate, a third through groove is provided on the first arm, and a fourth through groove is provided on the second arm; the electrode testing fixture also includes a first fastener, which passes through the third through groove, the first through groove, the second through groove and the fourth through groove in sequence.
[0010] In some embodiments of this application, a first through groove extends along the length direction of a first clamping plate, a second through groove extends along the length direction of a second clamping plate, a first fastener is connected to a second arm, and the first arm and the second arm clamp the stacked first clamping plate and the second clamping plate.
[0011] In some embodiments of this application, the third through slot and the fourth through slot extend in a direction parallel to the probe, the first fastener and the second arm are connected, and the first arm and the second arm clamp the first clamping plate and the second clamping plate that are stacked together.
[0012] In some embodiments of this application, the first clamping plate has a first hole and the second clamping plate has a second hole; the electrode testing fixture also includes a second fastener, which passes through the first hole and the second hole in sequence and is connected to the second clamping plate.
[0013] In some embodiments of this application, the electrode testing fixture further includes a gasket, which is sandwiched between a first clamping plate and a second clamping plate, and the gasket and the first clamping plate clamp a probe.
[0014] To achieve the above objectives, the present invention provides an electrolytic cell device, which includes multiple inspection plates and electrode testing fixtures of any of the above, with multiple probes electrically connected to the multiple inspection plates one by one.
[0015] The beneficial effects of this utility model are as follows:
[0016] The first and second clamping plates are stacked together, with their opposite ends placed in the clamping plate slots. One end of the bracket clamps the first and second clamping plates, and the other end is connected to the electrical equipment such as the electrolytic cell to be tested. Multiple probes are inserted between the first and second clamping plates. After the frame is stably installed on the electrical equipment to be tested through bolting, welding, or other methods, it is only necessary to use the first and second clamping plates to clamp the corresponding number of probes, and set the probe spacing to correspond to the electrode plate to be tested. Then, the first and second clamping plates are inserted into the clamping plate slots to make the probes electrically connected to the electrode plate to be tested, thus achieving batch assembly of probes.
[0017] Compared with existing technologies, the electrode testing fixture provided by this utility model is easier to assemble. It eliminates the need for independent fixing of each probe; simply pushing the first and second clamping plates into the clamping slots allows the probes clamped between them to naturally establish an electrical connection with the electrode plate under test. Furthermore, because the number of disassemblies and reassemblies between the bracket and the electrical device under test is reduced, it can even be placed on the device's housing for extended periods. Therefore, installation methods with higher connection strength, such as riveting and welding, can be used, resulting in superior connection stability of the entire electrode testing fixture, making it less susceptible to environmental disturbances and ensuring more reliable test data.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Please see Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of the overall structure of the electrode testing fixture 10 provided in this embodiment of the present invention. Figure 2 This is a schematic diagram of the application scenario of the electrode testing fixture 10 provided in this embodiment of the utility model.
[0031] In order to solve the technical problems of complex assembly and unstable connection of test fixtures in the existing electrolytic cell inspection process, this utility model discloses an electrode test fixture 10. The electrode test fixture 10 includes a support 11, a first clamping plate 12 and a second clamping plate 13 connected to the support 11, and a plurality of probes 14 assembled between the first clamping plate 12 and the second clamping plate 13.
[0032] Specifically, the bracket 11 includes a frame 111, a first arm 112 and a second arm 113. The frame 111 is used to connect with the electrical equipment under test. The first arm 112 and the second arm 113 are respectively connected to the frame 111. The first arm 112, the second arm 113 and the frame 111 form a clamping groove 114. The first clamping plate 12 and the second clamping plate 13 are stacked together and their opposite ends are placed in the clamping groove 114. A plurality of probes 14 are inserted between the first clamping plate 12 and the second clamping plate 13.
[0033] For clarity, the assembly method of the electrode testing fixture 10 in this embodiment is also described here. The following assembly steps are only one way of using the electrode testing fixture 10 in this embodiment, and are for illustrative purposes only. They should not be used to limit the scope of protection of this utility model. An electrical device to be tested is provided, which includes at least a plurality of exposed electrode plates for collecting electrical signals. A bracket 11 is fixed to the housing of the electrical device to be tested, such as an electrolytic cell. Optional fixing methods include threaded connection, riveting, and welding, such that the opening of the clamping plate groove 114 faces away from the electrode plate to be tested. A plurality of probes 14 are clamped using a first clamping plate 12 and a second clamping plate 13. The spacing of the probes 14 is set according to the position of the electrode plate to be tested. The probes 14 can be arranged in parallel or clamped at a certain angle, as long as it is feasible. The probe 14 is electrically connected to the electrode plate under test. For electrical devices under test with multiple electrode plates stacked, the probes 14 are preferably arranged in parallel, and the spacing between adjacent probes 14 is configured to be the thickness of the electrode plate, so that the probes 14 can be inserted between the gaps of each substrate. The first clamping plate 12, the second clamping plate 13, and the probes 14 are placed into the clamping slot 114, so that the first arm 112 and the second arm 113 clamp the first clamping plate 12 and the second clamping plate 13, and the multiple probes 14 are electrically connected to the multiple electrode plates under test one by one. When it is necessary to replace the sampling electrode plate, it is only necessary to remove the first clamping plate 12, the second clamping plate 13, and the probes 14 as a whole, adjust the number and position of the clamped probes 14, and reinsert them into the clamping slot 114 to start a new round of data acquisition.
[0034] In this embodiment, because the bracket 11 and the probe 14 are separate, the bracket 11, which is smaller in size and has a longer service life, can be installed on the electrical equipment under test for a long time. Therefore, a more stable connection method such as welding or riveting can be selected. The position of the probe 14, which needs to be frequently adjusted according to the electrode plate type and the test data, can be fixed by simply placing it between the first clamping plate 12 and the second clamping plate 13 and clamping it. Then, the first clamping plate 12, the second clamping plate 13 and the probe 14 are pushed into the clamping plate groove 114 to achieve batch electrical connection between the probe 14 and the electrode plate. Compared with the prior art, the electrode test fixture 10 disclosed in this embodiment is quick to assemble and disassemble, has a stable connection, and has high reliability of sampling data.
[0035] Please refer to the following: Figure 3 and Figure 4 As shown, Figure 3 It is along Figure 1 A partial cross-sectional view of line AA. Figure 4 yes Figure 1 The enlarged view of region B shows the specific structure of the first clamping plate 12 in some embodiments and the cooperation relationship between the first clamping plate 12, the second clamping plate 13 and the probe 14.
[0036] In some embodiments of this application, the first clamping plate 12 has multiple first positioning grooves 121 on the side facing the second clamping plate 13, and multiple probes 14 are respectively assembled in the first positioning grooves 121.
[0037] The first positioning groove 121 facilitates the positioning of the probe 14, especially when a large number of probes 14 are arranged side by side. The probe 14 can be automatically aligned by simply spreading it on the surface of the first clamping plate 12 and embedding it into the first positioning groove 121. On the other hand, after the probe 14 is partially inserted into the first positioning groove 121, it can also prevent the probe 14 from sliding between the first clamping plate 12 and the second clamping plate 13. Compared with clamping between two planes, the first clamping plate 12 with the first positioning groove 121 provides a more stable clamping of the probe 14.
[0038] Furthermore, multiple second positioning grooves 122 are provided on the side of the first clamping plate 12 away from the second clamping plate 13, and the spacing between adjacent first positioning grooves 121 is different from the spacing between adjacent second positioning grooves 122.
[0039] The separate arrangement of the first positioning groove 121 and the second positioning groove 122 allows the probe 14 to be positioned at different intervals when the first clamping plate 12 mates with the second clamping plate 13 with different surfaces to clamp the probe 14, thus adapting to more assembly requirements. It should be noted that this embodiment only provides a technical solution for setting the first positioning groove 121 and the second positioning groove 122. In fact, in some preferred embodiments, a third positioning groove, a fourth positioning groove, etc., can also be formed on the first clamping plate 12. This is an improvement that can be made by those skilled in the art without creative effort.
[0040] Please refer to the following: Figure 5 As shown, Figure 5 This is a partial cross-sectional schematic diagram of another first clamping plate 12 in an embodiment of this utility model.
[0041] Optionally, the first positioning groove 121 is a V-shaped groove or an arc groove, and adjacent first positioning grooves 121 are connected to each other.
[0042] The interconnected first positioning slots 121 allow the probe 14 to select its assembly position as needed. Sampling of different plates can be achieved by changing the number of first positioning slots 121 between adjacent probes 14. Similarly, changing the surface roughness of the first clamping plate 12 to impede the movement of the probe 14 between the first clamping plate 12 and the second clamping plate 13, or setting the side of the first clamping plate 12 facing the second clamping plate 13 to a wavy surface, can achieve a similar effect.
[0043] Please refer to the following: Figure 6 and Figure 7 As shown, Figure 6 yes Figure 1A magnified view of a portion of region C. Figure 7 It is along Figure 1 Another partial cross-sectional schematic diagram of line AA shows the fitting relationship between the first arm 112 and the second arm 113 clamping the first clamping plate 12 and the second clamping plate 13.
[0044] In some embodiments of this application, a first through groove 123 is provided on the first clamping plate 12, a second through groove 131 is provided on the second clamping plate 13, a third through groove 1121 is provided on the first arm 112, and a fourth through groove 1131 is provided on the second arm 113; the electrode testing fixture 10 also includes a first fastener 15, which passes through the third through groove 1121, the first through groove 123, the second through groove 131 and the fourth through groove 1131 in sequence.
[0045] The setting of the first fastener 15 can further enhance the fixing effect of the clamping groove 114 on the first clamping plate 12 and the second clamping plate 13, prevent the first clamping plate 12 and the second clamping plate 13 from sliding out of the clamping groove 114 and causing the first clamping plate 12 and the second clamping plate 13 to separate, and also ensure the reliability of the first clamping plate 12 and the second clamping plate 13 in clamping the probe 14.
[0046] Furthermore, the first through groove 123 extends along the length of the first clamping plate 12, the second through groove 131 extends along the length of the second clamping plate 13, the first fastener 15 is connected to the second arm 113, and the first arm 112 and the second arm 113 clamp the stacked first clamping plate 12 and the second clamping plate 13.
[0047] The first through groove 123 extends along the length of the first clamping plate 12, and the second through groove 131 extends along the length of the second clamping plate 13. This allows the first fastener 15 to move along the length of the first clamping plate 12 and the second clamping plate 13. That is, the first clamping plate 12 and the second clamping plate 13 can be finely adjusted relative to the bracket 11 before being fully locked, so as to change the electrode plate corresponding to the probe 14.
[0048] Optionally, the third through slot 1121 and the fourth through slot 1131 extend in a direction parallel to the probe 14, and the first fastener 15 and the second arm 113 are connected. The first arm 112 and the second arm 113 clamp the stacked first clamping plate 12 and the second clamping plate 13.
[0049] The third through groove 1121 and the fourth through groove 1131 extend in a direction parallel to the probe 14, which allows the first fastener 15 to move in a direction parallel to the length of the probe 14 to change the distance between the first clamping plate 12 and the second clamping plate 13 and the electrode plate to be tested, so that the probe 14 of the same length can measure the electrode plate at different depths.
[0050] Furthermore, the probe 14 includes a spring segment, which is disposed on the side of the first clamping plate 12 near the electrode plate to be tested. This ensures that when the first clamping plate 12 and the second clamping plate 13 approach or move away from the device under test, the probe 14 will not break due to squeezing the electrode plate, nor will it easily break off due to moving away from the electrode plate. This allows probes 14 of the same model to be used for batch sampling on multiple non-coplanar electrode plates.
[0051] In some embodiments of this application, the first clamping plate 12 has a first hole 124 and the second clamping plate 13 has a second hole 132; the electrode testing fixture 10 also includes a second fastener 16, which passes through the first hole 124 and the second hole 132 in sequence and is connected to the second clamping plate 13.
[0052] The second fastener 16 is positioned outside the clamping groove 114, providing additional fixing and clamping effect to the first clamping plate 12 and the second clamping plate 13. This avoids the situation where the middle part is loosened due to clamping only at the opposite ends of the first clamping plate 12 and the second clamping plate 13. The reinforcement effect of the second fastener 16 will be more obvious when the flexural strength of the first clamping plate 12 and the second clamping plate 13 is poor.
[0053] It should be noted that for the first fastener 15 and the second fastener 16, Figures 3 to 7 The diagram uses screws for illustration. In reality, the first fastener 15 can be a screw that is threaded to the second arm 113, or it can be a bolt and nut combination, or an expansion locking pin, etc. Similarly, the second fastener 16 can be replaced with any structure that can achieve the fastening effect according to the existing technology in the art, and is not limited to bolts.
[0054] In some embodiments of this application, the electrode testing fixture 10 further includes a gasket 17, which is sandwiched between the first clamping plate 12 and the second clamping plate 13, and the probe 14 is sandwiched between the gasket 17 and the first clamping plate 12.
[0055] The design of the gasket 17 means that the side of the probe 14 closest to the second clamping plate 13 is not in planar contact, which increases the resistance of the probe 14 sliding between the first clamping plate 12 and the second clamping plate 13 and increases the stability of the probe 14 positioning.
[0056] Please refer to the following: Figure 8 As shown, Figure 8 This is a schematic diagram of the overall structure of the electrolytic cell device provided in this embodiment of the utility model.
[0057] In order to solve the above-mentioned technical problems and facilitate the inspection and monitoring of each electrode in the electrolytic cell, this utility model also discloses an electrolytic cell device. The electrolytic cell device includes multiple inspection electrode plates 20 and the electrode testing fixture 10 disclosed in any of the above embodiments. Multiple probes 14 are electrically connected to the multiple inspection electrode plates 20 one by one.
[0058] Since the electrolytic cell device of this embodiment includes the electrode testing fixture 10 described above, this embodiment also has the technical effects of the above embodiment. That is, when the electrolytic cell device of this embodiment needs to sample the electrical signal of the inspection electrode plate 20, it can achieve the effect of quickly disassembling and assembling the fixture.
[0059] Specifically, the bracket 11 is fixed to the housing of the electrolytic cell device, such that the opening of the clamping slot 114 faces away from the inspection electrode 20; multiple probes 14 are clamped using the first clamping plate 12 and the second clamping plate 13, with the spacing of the probes 14 set according to the position of the inspection electrode 20; the entire assembly of the first clamping plate 12, the second clamping plate 13, and the probes 14 is placed into the clamping slot 114, such that the first arm 112 and the second arm 113 clamp the first clamping plate 12 and the second clamping plate 13, and the multiple probes 14 are electrically connected to the multiple inspection electrodes 20 to be tested in a one-to-one correspondence. When it is necessary to replace the inspection electrode 20 for sampling, simply remove the entire assembly of the first clamping plate 12, the second clamping plate 13, and the probes 14, adjust the number and position of the clamped probes 14, and reinsert them into the clamping slot 114 to start a new round of data acquisition.
[0060] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture. If the specific posture changes, the directional indicator will also change accordingly.
[0061] It should also be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on the other component or may be connected to an intermediary component. When a component is referred to as being "connected to" another component, it can be directly connected to the other component or indirectly connected to the other component through an intermediary component.
[0062] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.
