Description

Technical Field

[0001] This utility model belongs to the field of hydrogen fuel cell technology, and specifically relates to a hydrogen anode and cathode rib protection device. Background Technology

[0002] Anode and cathode ribs are key structural components supporting the anode and cathode plates in an electrolytic cell. They are typically made of conductive and corrosion-resistant metals, serving as the electrode fixing and conductive paths for current transmission and connecting to external circuits. Gas channels designed on the rib surface guide hydrogen / oxygen bubbles to quickly detach from the electrode surface and, in conjunction with a sealing structure, reduce the risk of gas leakage. Anode ribs promote oxygen evolution, while cathode ribs optimize hydrogen generation efficiency. Together, they ensure the efficient and stable operation of the electrolytic cell. However, traditional anode and cathode ribs lack active stress regulation and are unable to effectively cope with the high-frequency vibration impact caused by hydrogen fluctuations. Under long-term operation, this can easily lead to metal fatigue cracks or local deformation. Furthermore, when directly subjected to hydrogen pressure fluctuations or external impacts during operation, the high-frequency vibration energy cannot be effectively absorbed or dispersed, easily causing microcracks or plastic deformation at the rib and sealing interface due to repeated stress concentration. To address the problems mentioned above, we propose a hydrogen anode and cathode rib protection device. Utility Model Content

[0003] The purpose of this utility model is to provide a hydrogen anode and cathode rib protection device, which has the advantages of reinforced protection and buffer protection.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a hydrogen anode and cathode rib protection device, comprising a strip body, a fixing plate bolted to the bottom of the strip body, fixing frames bolted to both sides of the bottom of the fixing plate, a steel wire rope passing through and fixedly sleeved inside the fixing frame, brackets roped to both sides of the surface of the steel wire rope, a frame sleeve bolted to the opposite side of the two brackets, a fixing post fixedly sleeved inside the frame sleeve, a locking groove bolted to the center of the bottom of the fixing plate, a locking buckle engaging inside the locking groove, and the inside of the surface of the steel wire rope being fixedly sleeved with the inner wall of the locking buckle, and a buffer mechanism provided at the front and rear ends of the bottom of the two fixing frames away from one side.

[0005] The above technical solution involves connecting the wire rope to the supports on the two fixed columns, fixing the wire rope on both sides, and then fixing it to the fixing brackets on both sides of the fixing plate. The fixing plate supports the bottom of the strip, and the locking groove and buckle fix the middle of the wire rope and tighten it, generating an upward force to distribute the weight of the strip to the fixed columns, which can stabilize the strip. The pre-application of controllable mechanical constraint force significantly improves the deformation resistance and overall rigidity of the rib structure, effectively offsetting the periodic load impact caused by hydrogen fluctuations during electrolysis, and forming a self-balancing stress system in the key load-bearing parts of the protective device. This reduces the risk of fracture caused by metal fatigue and simplifies the stress adjustment process during later maintenance through the modular design of external anchor points.

[0006] The present invention is further configured such that the buffer mechanism includes a slide rod, the slide rod is bolted to the front end and rear end of the bottom of the two fixed frames away from one side, a spring is sleeved on the top of the surface of the slide rod, and a base plate is slidably sleeved through the middle of the surface of the slide rod.

[0007] The above technical solution employs a buffer mechanism. When the strip vibrates, the sliding rod moves up and down, causing the spring to contract. The base plate limits the movement of the sliding rod, and the opening is designed not to obstruct the movement of the sliding rod. This effectively mitigates the vibration transmission caused by hydrogen fluctuations or external impacts, preventing metal fatigue cracks or loosening of connectors due to high-frequency vibrations. The damping mechanism absorbs energy, maintaining the relative positional stability of the ribs and sealing structure, reducing the cumulative deformation of the protective device caused by long-term vibration, lowering the risk of hydrogen leakage caused by micro-displacement of the structure, extending the service life of key components, and reducing the frequency of unplanned downtime maintenance.

[0008] The present invention is further configured such that a base is bolted to the bottom of the base plate, and the base has openings at the front and rear ends near the middle sides, and the bottom of the slide rod surface penetrates the top of the opening.

[0009] The above technical solution provides a stable base and allows the sliding rod to move without obstruction.

[0010] The present invention is further configured such that module one is bolted to the left side of the top of the base away from the middle, module two is bolted to the right side of the top of the base away from the middle, and the bottom of the fixing column is bolted to the top of module one and module two.

[0011] The above technical solution is adopted: by setting up module one and module two, it can be connected by strips.

[0012] The present invention is further configured such that the buckle and the locking groove are configured to tighten the steel wire rope.

[0013] By adopting the above technical solution, the steel wire rope can be made to generate an upward force by setting it to tension.

[0014] The present invention is further configured such that the fixing plate is a corrosion-resistant structural vulcanized plate.

[0015] By adopting the above technical solution, the durability can be effectively improved by setting it as a corrosion-resistant structural vulcanized plate.

[0016] The present invention is further configured such that a limiting block is bolted to the top of the fixed column.

[0017] The above technical solution uses limit blocks to stabilize the frame.

[0018] The present invention is further provided that sealing rings are provided on both sides of the surface of the strip.

[0019] The above technical solution, by setting a sealing ring, can prevent leakage of the strip.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. This utility model significantly improves the deformation resistance and overall rigidity of the rib structure by applying controllable mechanical constraint force in advance, effectively offsetting the periodic load impact caused by hydrogen fluctuations during electrolysis, and enabling the key load-bearing parts of the protective device to form a self-balancing stress system. This not only reduces the risk of fracture caused by metal fatigue, but also simplifies the stress adjustment process during later maintenance through the modular design of external anchor points.

[0022] 2. This utility model can effectively mitigate the transmission of vibration caused by hydrogen fluctuations or external impacts, avoid metal fatigue cracks or loosening of connectors caused by high-frequency vibrations, absorb energy through the shock absorption mechanism, maintain the relative positional stability of the ribs and sealing structure, reduce the cumulative deformation of the protective device caused by long-term vibration, reduce the risk of hydrogen leakage caused by structural micro-displacement, extend the service life of key components, and reduce the frequency of unplanned downtime maintenance.
