As one of the core components of water electrolysis hydrogen production equipment, the voltage change of the electrolyzer plays a vital role in the efficiency and stability of the entire equipment. The current water electrolysis electrolyzer chamber voltage monitoring system is mainly composed of sensors, data acquisition and processing parts and display parts. Among them, the sensor is the core component of the electrolyzer chamber voltage monitoring system. Its function is to convert the voltage change in the electrolyzer chamber into an electrical signal for processing by the data acquisition and processing part. Commonly used electrolyzer chamber 7 voltage sensors include capacitive, resistive and voltage transmitters.

[0003] At present, there are two traditional methods for collecting the voltage of the electrolytic cell chamber: direct collection method and indirect collection method. The direct collection method is favored by some companies because it can directly obtain voltage parameters. The direct collection method is a method of connecting the voltage cable to the hanging hole of the electrolytic cell chamber. The hanging hole is generally an M4 or M6 threaded hole, and the voltage cable is generally 1.5mm 2 For RV or BV cables of or below, for the direct collection method, if there is no lifting hole on the electrolytic cell, it cannot be connected through the voltage cable. At the same time, if the width of the water electrolysis cell is small, using M4 bolts to connect may cause a short circuit between adjacent electrolytic cell cells, thereby causing an accident stop.

[0004] Based on the above analysis, the present application designs a voltage monitoring fixture for a water electrolysis cell chamber. Summary of the invention

DETAILED DESCRIPTION

[0024] The present invention will be further described in detail below in conjunction with specific implementations and with reference to the accompanying drawings. It should be emphasized that the following description is merely exemplary and is not intended to limit the scope of the present invention and its application.

[0025] like Figure 1-5As shown, it is a schematic diagram of the overall structure of a water electrolysis cell chamber voltage monitoring fixture provided in this embodiment, the fixture includes a pair of clamps 1 and a crossbeam frame 2 arranged between the two pairs of clamps 1, that is, the two clamps 1 are arranged on both sides, and the crossbeam frame 2 is located in the middle. As the name suggests, the clamps 1 should be used to connect with the corresponding components by clamping or clamping. The crossbeam frame 2 in this embodiment preferably includes two crossbeams, and the two crossbeams are locked on one side of the clamps 1 by a clamp 4, which is convenient for disassembly and subsequent maintenance. In other embodiments of the application, the two crossbeams can also be fixed to one side of the clamp 1 by welding, screwing, or plugging. The clamp 4 is an existing conventional guide rod fixing clamp, which is fixed to the clamp by bolts; the spacing between the two paired clamps 1 corresponds to the spacing between the cathode busbar 5 and the anode busbar 6 of the electrolytic cell, and the two clamps 1 can be clamped on the cathode busbar 5 and the anode busbar 6 respectively to fix the clamp as a whole. It can be understood that when the clamp 1 is connected to the busbar, it is only necessary to separate the two clamps 1 by clamping or clamping. The cathode and anode busbars (5, 6) can be fixed separately, and there is no need to change the busbar structure and the structure of the electrolytic cell chamber 7, and there is no need to open a lifting hole on the electrolytic cell chamber 7. The installation is quick and the installation speed of the fixture is improved. The crossbeam frame 2 is provided with probe assemblies 3 corresponding to the number of electrolytic cell chambers 7. The probe assemblies 3 can contact the surface of the electrolytic cell chamber 7 for voltage monitoring. It can be understood that the probe assembly 3 includes at least a probe 32, and each probe assembly 3 should be provided with a collection cable 34 connected to the voltage collection device, through which the probe can be collected. The voltage of the electrolytic cell chamber 7 monitored by the needle assembly 3 is transmitted to the voltage acquisition device. When using the probe assembly 3 for voltage monitoring, it is only necessary to bring the probe 32 into contact with the surface of the electrolytic cell chamber 7. There is no need to open a lifting hole on the electrolytic cell chamber 7, and there is no need to connect cables. In addition, the size of the probe 32 on the probe assembly 3 is about 5-15mm. The probe 32 of this diameter can ensure sufficient structural strength and stability without taking up too much space or interfering with the normal operation of the adjacent electrolytic cell chamber 7. Therefore, there is no need to worry about the occurrence of short circuit when using the probe assembly 3.

[0026] The probe assembly 3 includes a mounting base 31 and a probe 32. Figure 6-7As shown, the mounting seat 31 is a hollow cylindrical structure with an open upper end, and a connector 33 that can be connected to the crossbeam frame 2 is provided near the lower end of the mounting seat 31. It can be understood that the connector 33 can be a sleeve hole structure or a slot structure. The present embodiment is preferably a sleeve hole structure. The connector 33 is sleeved on the crossbeam frame 2. It can be understood that the connector 33 should fix the probe assembly 3 on the crossbeam frame 2 to avoid rotation and displacement and thus affect the monitoring effect or result; the probe 32 is arranged at the upper end of the mounting seat 31 through an elastic member 36. At the same time, a collection cable 34 is led out at the connection between the probe 32 and the mounting seat 31. The elastic member 36 is arranged between the probe 32 and the mounting seat 31, which is beneficial to increase the contact strength between the probe 32 and the surface of the electrolytic cell chamber 7, thereby avoiding poor contact and thus affecting the monitoring effect or result; in other embodiments of the present application, the probe assembly 3 may also be an existing banana plug with corresponding structure and function.

[0027] The specific structure of the connector 33 fixing the probe assembly 3 on the crossbeam frame 2 includes: the connector 33 cooperates with the crossbeam frame 2 in an interference fit manner, or a locking member is provided on the connector 33, and the probe assembly 3 is fixed to the measuring frame by the locking member. In this embodiment, a locking member is preferably provided on the connector 33, and the locking member is a locking bolt and a locking hole 35 provided on the connector 33. The advantage of using the locking member is that the position of the probe assembly 3 on the measuring frame can be adjusted by adjusting the tightness of the locking member, which is convenient for adapting to electrolytic cells of different structures and improving flexibility.

[0028] The clamping member 1 is a U-shaped structure, that is, a groove-shaped structure. The clamping width of the clamping member 1 of this structure corresponds to the thickness of the cathode and anode busbars (5, 6). At present, the thickness of the cathode and anode busbars (5, 6) of the water electrolysis cell is generally about 150-200 mm, so the clamping space of the clamping member 1 is preferably 150 (+2) -200 (+2) mm; the depth of the clamping member 1 is greater than or equal to 12 mm and less than or equal to 200 mm; considering the support strength, the thickness of the clamping member 1 is set to about 14 mm in this embodiment.

[0029] Taking into account the problem of clamping tightness, a locking piece is provided on the clamping piece 1 in this embodiment, through which the clamping piece 1 can be fixed on the cathode and anode busbars (5, 6). Compared with direct clamping, the stability of the clamping can be improved to ensure the accuracy and safety of the collection. The locking piece is preferably a locking bolt. It can be understood that a locking hole 11 corresponding to the locking bolt should be provided on the clamping piece. Tightening or releasing the locking bolt can realize the connection and separation of the clamping piece 1 and the cathode and anode busbars (5, 6).

[0030] Alternatively, in other embodiments of the present application, the clamp 1 may also be an elastic clamp, and when the clamping space of the clamp 1 is adjusted to correspond to the thickness of the cathode and anode busbars (5, 6), the clamp 1 can be clamped on the cathode and anode busbars (5, 6) under the action of elastic force, and the structure of the elastic clamp may be an existing conventional U-shaped elastic clamp structure.

[0031] The length of the side of the U-shaped clamp 1 of this embodiment close to the crossbeam frame 2 is greater than the length of the side on the opposite side, that is, the side of the clamp 1 close to the crossbeam frame 2 is the long side, and the crossbeam frame 2 is detachably fixed on the long side by the clamp 4, so that it is convenient to adjust the distance between the crossbeam frame 2 and the surface of the electrolytic cell chamber 7 as needed, and then adjust the distance between the probe assembly 3 and the surface of the electrolytic cell chamber 7 to ensure that the contact force between the probe assembly 3 and the surface of the electrolytic cell chamber 7 is moderate, so that there will be no poor contact of the probe 32, and there will be no problem of damage to the probe 32 due to strong squeezing force on the probe 32.

[0032] The use principle of this embodiment includes: fixing a corresponding number of probe assemblies 3 on the crossbeam frame 2 in advance according to the number of electrolytic cell chambers 7, and adjusting the position of the probe assemblies 3 on the crossbeam frame 2 to ensure that they can correspond to the position of each chamber in the electrolytic cell chamber 7 area. It should be noted that after the probe assemblies 3 are adjusted to a suitable position, each probe assembly 3 is fixed to the crossbeam frame 2 by a locking bolt to avoid displacement, and then the two clamps 1 are clamped on the corresponding cathode and anode busbars (5, 6). At the same time, each clamp 1 is fixed to the busbar by a locking bolt, and finally the collection cable 34 led out from the probe assembly 3 is connected to the voltage collection equipment for voltage monitoring and collection.

[0033] It can be seen that the clamp of the present embodiment abandons the existing method of connecting the voltage cable with the hanging hole on the electrolytic cell chamber 7 by bolts. In this way, there is no need to open a hanging hole on the electrolytic cell chamber 7, nor is there any need to worry about the occurrence of short circuit problems between adjacent electrolytic cell chambers 7 due to the small width of the electrolytic cell chamber 7, and there is no need to perform wiring operations. The clamp of the present application only needs to fix the clamp 1 on the cathode and anode busbars (5, 6), and adjust each probe assembly 3 to contact the surface of the electrolytic cell chamber 7 at the corresponding position. Therefore, compared with the existing method, the clamp can simplify the wiring process when monitoring the voltage of the electrolytic cell chamber 7, and can improve the accuracy of voltage monitoring. There is no need to worry about the occurrence of short circuits or abnormal contact events, which reduces the cost of use of enterprises and has certain economic benefits and market value.

[0034] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several improvements can be made without departing from the premise of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of the claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
