Description

Technical Field

[0001] The present invention relates to the technical field of electrolytic cell detection equipment, and in particular to a testing device for an electrolytic cell for producing hydrogen by electrolyzing water and an operating method thereof. Background Art

[0002] In the process of electrolysis of water to produce hydrogen, the electrolyzer is one of the key structures of the electrolysis of water to produce hydrogen. Its function is to use electric current to pass through aqueous solution or water vapor to decompose water molecules to generate hydrogen and oxygen. The electrolyzer consists of a cell body, an anode and a cathode. Most of them use a diaphragm to separate the anode chamber and the cathode chamber to form an electrolyzer unit. According to the different electrolytes, it is divided into three categories: aqueous solution electrolyzer, molten salt electrolyzer and non-aqueous solution electrolyzer. When direct current passes through the electrolyzer, an oxidation reaction occurs at the interface between the anode and the solution, and a reduction reaction occurs at the interface between the cathode and the solution to produce the desired product. Optimizing the design of the electrolyzer structure and reasonably selecting the electrode and diaphragm materials are the key to improving current efficiency, reducing cell voltage and saving energy. When current is passed through the electrolyte inside the electrolyzer, detection equipment is needed to detect the current of the electrolyzer unit, voltage and temperature under different current conditions.

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0032] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0034] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0035] like Figures 1 to 6 As shown, the testing device for the electrolyzer for producing hydrogen by electrolysis of water according to the embodiment of the present invention comprises a support frame 1, a mounting seat 2 and a probe 3. The mounting seat 2 is slidably connected to the support frame 1 along the vertical direction (the vertical direction is the Z direction shown in the figure), and the mounting seat 2 can be selectively fixed to the support frame 1; a plurality of probes 3 are detachably connected to the mounting seat 2 along a first direction (the first direction is the X direction shown in the figure), each probe 3 corresponds to abutting an electrolyzer unit, the probe 3 is used to test the current of the electrolyzer unit, and each probe 3 can move along the vertical direction and be selectively fixed to the mounting seat 2.

[0036] It can be understood that by detachably arranging multiple probes 3 on the mounting base 2, the test device of the electrolyzer for producing hydrogen from water by electrolysis can adapt to different numbers of electrolyzer units for testing, thereby improving the practicality of the test device of the electrolyzer for producing hydrogen from water by electrolysis; by adjusting the height of the mounting base 2 on the support frame 1, the overall height of all probes 3 can be adjusted, so that the test device of the electrolyzer for producing hydrogen from water by electrolysis can test electrolyzer units of different thicknesses; by independently adjusting the height of each probe 3 on the mounting base 2, each probe 3 can independently adapt to each electrolyzer unit of different thicknesses, thereby effectively enhancing the degree of freedom of adjustment of the probe 3, and effectively improving the compatibility of the test device of the electrolyzer for producing hydrogen from water by electrolysis, thereby reducing the waste of time and cost in making different test devices for electrolyzer units of different thicknesses.

[0037] Furthermore, if Figure 2 , Figure 3 and Figure 4 As shown, the probe 3 includes a test rod 31 and a spring 32, and the test rod 31 is connected to the mounting seat 2 through the spring 32, and the spring 32 always has a moving tendency to drive the test rod 31 to abut against the electrolyzer unit. Through the setting of the spring 32, the test rod 31 can be kept in a tight state with the electrolyzer unit under the drive of the spring 32, thereby ensuring the stability of the test rod 31 abutting the test, and reducing the situation of poor contact or short circuit. And the test rod 31 is connected to the mounting seat 2 through the spring 32 to achieve a buffer connection, which can reduce the situation of hard collision between the test rod 31 and the electrolyzer unit when adjusting in the vertical direction, improve the use safety of the test device for the electrolytic water hydrogen production electrolyzer, and ensure the structural safety of the electrolyzer unit.

[0038] Furthermore, the probe 3 also includes an insulating sleeve 33 and a first nut 34, the insulating sleeve 33 is connected to the mounting seat 2, the test rod 31 is slidably connected to the inner wall of the insulating sleeve 33, the inner wall of the insulating sleeve 33 is provided with a first stopper 331 in a ring-shaped protrusion around its own central axis, the outer periphery of the test rod 31 is provided with a second stopper 311 in a ring-shaped protrusion around its own central axis, the two ends of the spring 32 are respectively connected to the first stopper 331 and the second stopper 311, the inner wall of the first nut 34 is provided with a third stopper 341 in a ring-shaped protrusion around its own central axis, the first nut 34 is sleeved on the outer periphery of the test rod 31, the outer peripheral wall of the insulating sleeve 33 and one end adjacent to the electrolytic cell unit is provided with a first thread 332, the first nut 34 has a second thread inside, the first thread 332 cooperates with the second thread, and the second stopper 311 is slidably connected between the first stopper 331 and the third stopper 341.

[0039] It can be understood that the probe 3 has a simple structure and is easy to assemble and disassemble. When assembled, the spring 32 is sleeved outside the test rod 31 and located above the second stopper 311, and then the test rod 31 is inserted into the insulating sleeve 33, so that the spring 32 is located between the first stopper 331 and the second stopper 311, and then the first nut 34 is sleeved outside the test rod 31 and located below the second stopper 311, and the first nut 34 is screwed to connect the first nut 34 with the insulating sleeve 33, so as to achieve the installation of the test rod 31. And by using the insulating sleeve 33 to slide and guide the test rod 31, the stability of the movement of the test rod 31 driven by the spring 32 is effectively improved, and the shaking of the test rod 31 is reduced, so as to ensure the stability of the abutment between the test rod 31 and the electrolytic cell unit and the position accuracy of the abutment.

[0040] Optionally, the probe 3 further includes a fixing seat 35 and at least two second nuts 36, the fixing seat 35 is connected to the mounting seat 2, the fixing seat 35 is provided with a first connection hole 351 in the vertical direction, the insulating sleeve 33 is slidably connected to the first connection hole 351, the outer peripheral wall of the insulating sleeve 33 and one end away from the electrolytic cell unit is provided with a third thread 333, the second nut 36 is provided with a fourth thread 361, the third thread 333 and the fourth thread 361 are threadedly matched, and the two second nuts 36 are threadedly connected to the insulating sleeve 33 and respectively press against both sides of the mounting seat 2 in the vertical direction. The insulating sleeve 33 is inserted into the first connection hole 351, and the second nuts 36 located on both sides of the mounting seat 2 in the vertical direction are screwed so that the second nuts 36 press against the mounting seat 2 to adjust and install the insulating sleeve 33, effectively ensuring the connection stability of the insulating sleeve 33 in the vertical direction, thereby ensuring the test stability of the probe 3. When the height of the probe 3 needs to be adjusted, the second nuts 36 on both sides of the mounting base 2 are loosened to adjust the corresponding position of the mounting base 2 and then the second nuts 36 are tightened. The threaded connection is stable and easy to adjust.

[0041] Of course, in other embodiments, the fourth thread 361 can be directly set in the first connection hole 351 of the fixing seat 35, and the third thread 333 is set on the outer peripheral wall of the insulating sleeve 33 and the end away from the electrolytic cell unit. The third thread 333 and the fourth thread 361 are threadedly matched, and the insulating sleeve 33 is directly screwed into the first connection hole 351 to adjust the height of the insulating sleeve 33. When operating this structure, it is necessary to pay attention to avoid the entanglement of the wire of the probe 3. In addition, it can also be adjusted by setting other sliding locking structures such as bolt locking on the slide rail slide seat, and too many specific examples are not given here.

[0042] Furthermore, if Figures 1 to 4As shown, the test device of the electrolytic water hydrogen production electrolyzer also includes a first bolt 4, a mounting seat 2 is provided with a mounting groove 21 along the vertical direction, and the length of the mounting groove 21 extends along the first direction, a fixing seat 35 is inserted in the mounting groove 21 and can rotate relative to the mounting seat 2, and the rotation axis of the fixing seat 35 extends along the second direction, and the mounting seat 2 is provided with a plurality of second connecting holes 22 on both sides along the second direction. All the second connecting holes 22 on each side of the two sides along the second direction of the mounting seat 2 are arranged at intervals along the first direction, and the outer peripheral wall of the fixing seat 35 is symmetrically provided with two first threaded holes 352, and the two first bolts 4 respectively pass through the two second connecting holes 22 arranged oppositely on the two sides of the mounting seat 2 along the second direction, and are respectively screwed into the first threaded holes 352 arranged oppositely on the fixing seat 35, so as to fix the fixing seat 35 to the mounting seat 2, wherein the first direction, the second direction and the vertical direction are arranged perpendicular to each other.

[0043] That is, the angle adjustment of the insulating sleeve 33 and the test rod 31 can be achieved by rotating the fixing seat 35, so as to meet the position requirements of different angle test points, with high adaptability, and effectively improve the practicality and compatibility of the probe 3. During installation, it is only necessary to place the fixing seat 35 in the installation groove 21, and align the first threaded holes 352 on both sides of the fixing seat 35 along the second direction with the second connection hole 22 on the mounting seat 2. Under necessary conditions, the fixing seat 35 is rotated to adjust the test angle position of the test rod 31, and the first bolt 4 is screwed through the second connection hole 22 and inserted into the first threaded hole 352 to achieve the installation of the fixing seat 35. The structure is simple and the operation is convenient. The fixing seat 35 is locked by the first bolt 4 on both sides along the second direction, and the connection is stable. It should be noted that even if the first threaded hole 352 is connected to the first connection hole 351, the screwing depth of the first bolt 4 cannot be exposed to the hole wall of the first connection hole 351 and abut against the insulating sleeve 33, so as to ensure the convenience of adjustment of the insulating sleeve 33.

[0044] Preferably, if Figure 1 and Figure 2 As shown, the outer peripheral wall of the fixing seat 35 has two anti-rotation planes 353 arranged along the second direction, and the two anti-rotation planes 353 are respectively in contact with the groove walls of the mounting groove 21 arranged along the second direction, and the first threaded hole 352 is arranged on the anti-rotation plane 353. Through the setting of the anti-rotation plane 353, on the one hand, the area of ​​the connection surface between the fixing seat 35 and the mounting seat 2 can be increased, the shaking of the fixing seat 35 can be reduced, the connection stability between the fixing seat 35 and the mounting seat 2 can be improved, and the rotation axis of the fixing seat 35 extending in the vertical direction and the rotation axis extending in the first direction can be avoided, thereby improving the installation stability of the fixing seat 35; on the other hand, the cooperation between the anti-rotation plane 353 and the groove wall of the mounting groove 21 can be used to improve the plug-in convenience of the fixing seat 35, thereby improving the alignment convenience of the first threaded hole 352 and the second connection hole 22, and facilitating the installation of the fixing seat 35.

[0045] Alternatively, if Figure 2 , Figure 3 and Figure 4 As shown, the test rod 31 includes a connecting rod 312 and a probe 313. The connecting rod 312 is connected to the mounting seat 2. The probe 313 is detachably connected to the connecting rod 312, and the probe 313 abuts against the electrolytic cell unit. The probe 313 abuts against the electrolytic cell unit during use, so after a period of use, the contact end of the test rod 31 and the electrolytic cell unit can be replaced by replacing the probe 313, thereby ensuring the structural quality of the contact end of the test rod 31 and the electrolytic cell unit and reducing the maintenance cost of the test rod 31. Of course, the shape of the probe 313 can be pointed, flat or round, etc., which is convenient for replacing the shape of the probe 313 to adapt to the structure of different electrolytic cell units.

[0046] In this embodiment, a boss is protruding from the side of the probe 313 away from the electrolytic cell unit, and a fifth thread is arranged on the outer periphery of the boss. A circle of surrounding walls is arranged on the side of the connecting rod 312 facing the electrolytic cell unit, and a sixth thread is arranged on the inner wall of the surrounding wall. The fifth thread cooperates with the sixth thread, and the probe 313 is screwed so that the boss is inserted into the surrounding wall to realize the connection between the probe 313 and the connecting rod 312. The threaded connection is stable and easy to disassemble and assemble. Of course, in addition to the boss and the surrounding wall being connected by threaded connection, the boss can also be connected to the surrounding wall by rotating the buckle.

[0047] In addition, the test device of the electrolytic cell for producing hydrogen from water by electrolysis also includes a temperature sensing element, which is connected to the test rod 31. By setting the temperature sensing element to fit the test rod 31 to monitor the temperature of the test rod 31, the temperature of the electrolytic cell unit abutted by the test rod 31 can be monitored, thereby enriching the functionality of the test device of the electrolytic cell for producing hydrogen from water by electrolysis.

[0048] In some embodiments, Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the test device of the electrolytic water hydrogen production electrolyzer also includes a second bolt 5, the support frame 1 includes two brackets 11 arranged at intervals along the first direction, and a sliding groove 111 is provided on one side of the two brackets 11 adjacent to each other, and the sliding groove 111 extends in the vertical direction and at least penetrates the top surface of the bracket 11, and the two groove walls of the sliding groove 111 along the second direction are relatively protruding and provided with a fourth stopper 112, and the fourth stopper 112 is adjacent to the notch of the sliding groove 111, and the mounting seat 2 is provided at both ends along the first direction. There are clamping parts 232, and the two clamping parts 232 are respectively slidably set in the sliding grooves 111 of the two brackets 11, and the clamping parts 232 are located between the fourth stopping part 112 and the bottom of the sliding groove 111. The clamping part 232 is penetrated by a second threaded hole 2321 along the first direction. The second bolt 5 is screwed through the second threaded hole 2321 and pressed against the bottom of the sliding groove 111 until the clamping part 232 is pressed against the fourth stopping part 112, wherein the first direction, the second direction and the vertical direction are perpendicular to each other.

[0049] It is understandable that the clamping parts 232 at both ends of the mounting seat 2 along the first direction are slidably arranged in the sliding grooves 111 of the two brackets 11 to ensure the guiding and stability of the mounting seat 2 in the vertical direction. By setting the fourth stopper 112, the clamping part 232 is limited between the fourth stopper 112 and the bottom of the sliding groove 111 to prevent the clamping part 232 from escaping from the sliding groove 111. During installation, it is only necessary to align the clamping part 232 of the mounting seat 2 with the sliding groove 111, insert it from the top surface of the bracket 11 into the sliding groove 111, adjust the height of the mounting seat 2, and then use the second bolt 5 to screw through the second threaded hole 2321 to abut against the bottom of the sliding groove 111, and continue to screw so that the clamping part 232 and the fourth stopper 112 are tightly pressed to achieve the adjustment and installation of the mounting seat 2.

[0050] Furthermore, if Figure 5 and Figure 6As shown, the mounting seat 2 includes a first connection block 23, a second connection block 24 and at least two mounting blocks 25, the probe 3 is arranged on the mounting block 25, the mounting block 25 is provided with connection grooves 251 on both sides along the first direction, the length of the second connection block 24 extends along the first direction, the two ends of the second connection block 24 are respectively detachably connected to the connection grooves 251 of two adjacent mounting blocks 25, the first connection block 23 includes a connection portion 231 and a clamping portion 232 arranged at an angle, and the connection portion 231 is detachably connected to the connection groove 251 of the mounting block 25 adjacent to one end of the bracket 11. That is, each mounting block 25 is provided with a mounting groove 21 and a plurality of second connection holes 22 for connecting a plurality of probes 3. When the span of the electrolyzer unit is large or the number is large and one mounting block 25 cannot meet the installation of the probe 3, a plurality of mounting blocks 25 can be spliced ​​through the connection block to improve the installation capacity of the mounting seat 2 and improve the applicability of the test device for the electrolyzer for producing hydrogen by electrolysis of water, so as to be compatible with the test of more electrolyzer units. The mounting seat 2 is split into a plurality of parts such as a mounting block 25 and a first connecting block 23 for production, which is convenient for production, manufacturing, maintenance and replacement.

[0051] Taking the splicing of two mounting blocks 25 as an example, two groups of third connecting holes communicating with two connecting grooves 251 are respectively provided on the top surface of the mounting block 25, and each group of third connecting holes includes two third connecting holes spaced along the second direction. Two groups of third threaded holes are spaced along the first direction on the second connecting block 24, and each group of third threaded holes includes two third threaded holes spaced along the second direction.
