[0030] During the operation of the hydrogen electrolyzer 100, the stability of the electrode plate 101 is crucial. In related technologies, the support device often cannot effectively monitor in real time whether the electrode plate 101 of the electrolyzer 100 has sunk. If the sinking of the electrode plate 101 is not detected and dealt with in time, it may cause sealing problems such as leakage of the electrolyzer 100, affecting the normal operation of the electrolyzer 100, or even causing equipment damage.

[0031] To address the aforementioned technical problems, this utility model proposes a support device.

[0032] As attached Figure 1 The diagram shown is a schematic representation of the overall structure of the support device in an embodiment of this utility model; as shown in the attached diagram. Figure 2 As shown, Figure 1 Top view; as attached Figure 3 The diagram shown is a structural schematic of the support device used to support the electrolytic cell 100 in an embodiment of this utility model; as shown in the attached diagram. Figure 4 As shown, Figure 3 A cross-sectional view of the support assembly 3 and the electrolytic cell 100, cut along line AA. The support assembly supports the electrolytic cell 100, which includes electrode plates 101 and end pressure plates 102 disposed on both sides of the electrode plates 101. (From the attached...) Figure 1-4 It is known that the support device includes a support base 1, at least one movable component 2, and at least two support components 3.

[0033] The support base 1 has a first track 11 on at least one side. A movable component 2 is slidably disposed on the first track 11, and the movable component 2 is used to connect with an end pressure plate 102. During the operation of the electrolytic cell 100, the dimensions of the electrode plates 101 of the electrolytic cell 100 will change along the extension direction of the first track 11. The end pressure plate 102 is placed on the movable component 2, and the movable component 2 can slide on the first track 11 to adjust the position of the end pressure plate 102 as the dimensions of the electrode plates 101 change, so that the movable component 2 can accurately support the electrode plates of the electrolytic cell 100.

[0034] At least two support components 3 are arranged on the support base 1. The support components 3 include multiple checkweighers 31 and are used to support the electrode plate 101. The multiple checkweighers 31 can monitor the weight distribution changes of the electrode plate 101 on the support base 1 in real time, so as to promptly remind or take corresponding measures when the electrode plate 101 sinks, so as to avoid leakage or damage to the electrolytic cell 100 caused by the sinking of the electrode plate 101.

[0035] As can be seen from the above embodiments, when the electrode plate 101 sinks, the weight distribution of the electrode plate 101 on the support base 1 will change. Multiple checkweighers 31 can monitor the change in weight distribution of the electrode plate 101 on the support base 1 in real time, so that when the electrode plate 101 sinks, timely reminders or corresponding measures can be taken to avoid the problem of leakage and damage to the electrolytic cell 100 caused by the sinking of the electrode plate 101.

[0036] For example, the support device is equipped with an alarm device (not shown in the figure). The checkweigher sensor 31 can monitor the weight distribution changes of the electrode plate 101 on the support base 1 in real time and transmit the weight signal to the external control system or electrical control box 4. By using a preset weight threshold, the external control system or electrical control box 4 can determine whether the electrode plate 101 of the electrolytic cell 100 has sunk, thereby issuing an alarm in time or reminding the staff to take appropriate measures.

[0037] As attached Figure 3-4 As shown, in some embodiments, the support assembly 3 includes a checkweighing plate 32, and a checkweighing sensor 31 is disposed below the checkweighing plate 32 and connected to the checkweighing plate 32. When the support device is used to support the electrolytic cell 100, the electrode plate 101 is located above the checkweighing plate 32. The checkweighing plate 32 is used to support the electrode plate 101, so that the checkweighing sensor 31 below the checkweighing plate 32 can detect the weight of the electrode plate 101.

[0038] As attached Figure 4As shown, in some embodiments, the electrolytic cell 100 is provided with a plurality of insulating sleeves 103, which are evenly arranged along the periphery of the electrode plate 101. The insulating sleeves 103 are fitted onto the tensioning screw of the electrolytic cell 100 to ensure the insulation performance between the tensioning screw and the support assembly 3 and to prevent current leakage.

[0039] The support assembly 3 includes a first assembly 33 and a second assembly 34, which are staggered and positioned above the checkweighing plate 32. The first assembly 33 includes a first support portion 331 and a second support portion 332, with a first support gap 333 between them. An insulating sleeve 103 is fitted into the first support gap 333. The first and second support portions 331 and 332 clamp the insulating sleeve 103, enhancing the structural stability of the support assembly 3 and thus enabling it to better support the weight of the electrode plate 101.

[0040] The second component 34 includes a third support portion 341 and a fourth support portion 342, with a second support gap 343 between the third support portion 341 and the fourth support portion 342. An insulating sleeve 103 is fitted into the second support gap 343. Similarly, the third support portion 341 and the fourth support portion 342 clamp the insulating sleeve 103, enhancing the structural stability of the support component 3, thereby enabling it to better support the weight of the electrode plate 101.

[0041] As attached Figure 4 As shown, in some embodiments, the cross-sections of the first support portion 331, the second support portion 332, the third support portion 341, and the fourth support portion 342 are all approximately triangular, and a receiving groove 35 is provided between the first component 33 and the second component 34, with an insulating sleeve 103 being secured in the receiving groove 35. The receiving groove 35 limits the position of the insulating sleeve, preventing displacement and enhancing the stability of the support component 3 in supporting the electrode plate 101.

[0042] As attached Figure 4 As shown, in some embodiments, the first support portion 331, the second support portion 332, the third support portion 341, and the fourth support portion 342 are all connected to the checkweighing plate 32. The first support portion 331, the second support portion 332, the third support portion 341, and the fourth support portion 342 limit and fix the electrode plate 101. The weight of the electrode plate 101 presses on the checkweighing plate 32, and the weight distribution change of the electrode plate 101 on the support base 1 can be monitored by multiple checkweighing sensors 31 below the checkweighing plate 32.

[0043] As attached Figure 4As shown, in some embodiments, the support assembly 3 includes a base plate 36, which has a detection groove 361. A checkweigher sensor 31 is disposed on the base plate 36 of the detection groove 361, and a checkweigher plate 32 is disposed within the detection groove 361. When the weight distribution of the electrode plate 101 on the support base 1 changes, the position of the checkweigher plate 32 within the detection groove 361 changes; that is, the checkweigher plate 32 can float up and down within the detection groove 361, so that the gravity of the checkweigher plate 32 presses down on multiple checkweighers 31, enabling the multiple checkweighers 31 to accurately detect changes in the weight distribution of the electrode plate 101 on the support base 1.

[0044] As attached Figure 1-3 As shown, in some embodiments, the support device includes an electrical control box 4, which includes a controller (not shown), a display (not shown), an indicator light (not shown), and control buttons (not shown). The electrical control box 4 is connected to the checkweigher 31. The controller receives weight information detected by multiple checkweigher sensors 31 and analyzes whether the electrode plate 101 has sunk based on the received weight information. If the electrode plate 101 is detected to have sunk, the display shows an abnormal weight, and the indicator light illuminates in red or yellow. The control buttons can be preset with a weight range so that the controller can determine whether the electrode plate 101 has sunk.

[0045] For example, the controller may include any suitable processing device with data processing and / or instruction execution capabilities. For instance, the controller may be implemented using one or a combination of several of the following processing units: programmable logic controller (PLC), digital signal processor (DSP), field-programmable gate array (FPGA), programmable logic array (PLA), central processing unit (CPU), application-specific integrated circuit (ASIC), microcontroller unit (MCU), and others. For example, the controller may be the master control chip in the support device, i.e., the master control MCU.

[0046] For example, multiple checkweighers 31 detect the weight of the checkweighing plate 32 and transmit the weight information to the control box 4 as an electrical signal. The electrical signal is divided into three levels: Level 1 is a weight signal indicating that the checkweighing plate 32 can bear the weight of the electrode plate 101, with the weight range of the electrode plate 101 being a first preset range. After receiving this Level 1 electrical signal, the control box 4 controls the indicator light to display green. Level 2 is a weight signal indicating that the checkweighing plate 32 bears a relatively large weight of the electrode plate 101, with the weight range of the electrode plate 101 being a second preset range. After receiving this Level 2 electrical signal, the control box 4 controls the indicator light to display yellow and indicates that the detection cycle should be shortened. Level 3 is an alarm signal indicating that the checkweighing plate 32 bears an excessive weight of the electrode plate 101, with the weight range of the electrode plate 101 being a third preset range. After receiving this Level 3 electrical signal, the control box 4 controls the indicator light to display red, requiring the plate to be returned to the factory for repair. The first preset range, the second preset range, and the third preset range can be set according to the actual situation. This utility model does not limit the first preset range, the second preset range, and the third preset range.

[0047] The electrical control box 4 is connected to the external control system. After receiving the third-level electrical signal sent by the checkweigher sensor 31, the electrical control box 4 transmits the electrical signal of the electrode plate 101 sinking to the external control system for shutdown interlocking to ensure the safe operation of the electrolytic cell 100.

[0048] As attached Figure 1-2 As shown, in some embodiments, the support base 1 is provided with at least two second tracks 12, and the support assembly 3 is disposed on the second tracks 12. Understandably, during operation, the dimensions of the electrode plate 101 of the electrolytic cell 100 change along the extension direction of the second track 12. The support base 1 slides on the second track 12 to adjust its position according to the change in the dimensions of the electrode plate 101, thus accommodating the change in dimensions of the electrode plate 101 along the extension direction of the second track 12. The extension direction of the first track 11 is perpendicular to the extension direction of the second track 12. The electrode plate 101 is cylindrical, the extension direction of the first track 11 is parallel to the axial direction of the electrode plate 101, and the extension direction of the second track 12 is parallel to the radial direction of the electrode plate 101. Furthermore, the plane containing the extension directions of the first track 11 and the second track 12 is parallel to the horizontal plane. That is, during operation, the dimensions of the electrode plate 101 in the axial direction and in the radial direction change.

[0049] As attached Figure 5As shown, in some embodiments, the movable component 2 includes a movable pulley 21 and a support plate 22. The movable pulley 21 is disposed below and connected to the support plate 22, and the support plate 22 is connected to a pressure plate 102 at one end. The support plate 22 supports the pressure plate 102 at the end, and the movable pulley 21 facilitates the movement of the support plate 22. When the electrode plate 101 of the electrolytic cell 100 changes size along the extension direction of the first track 11 during operation, the support plate 22 moves and generates friction with the first track 11. The movable pulley 21 can reduce the friction between the support plate 22 and the first track 11, preventing the support plate 22 from being worn.

[0050] In some embodiments, the support plate 22 is provided with lifting lugs 221 on both sides, and the end plate 102 is located between the two lifting lugs 221. The two lifting lugs 221 are used to limit the end plate 102 and prevent the end plate 102 from sliding out of the support plate 22.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
