When using an electrolytic cell electrode, the electrode is placed in the electrolytic cell through connecting wires, and the positive and negative terminals of the power supply are connected to different electrodes through different connecting wires, thereby enabling basic hydrogen electrolysis experiments.
[0003] In their daily work, the inventors discovered that the electrodes still have at least the following problems: When using electrodes in an electrolytic cell, the electrodes are placed in the electrolytic cell through connecting wires, and the positive and negative terminals of the power supply are connected to different electrodes through different connecting wires, so that basic hydrogen electrolysis experiments can be carried out. However, in actual use, the electrodes are generally smooth cylinders, which limits the contact area between the electrode and the solution, thus affecting the electrolysis efficiency to some extent. Utility Model Content

[0006] The effect achieved by the above components is as follows: when using the connecting device, the first and second semicircular rings are manually slid into the inside of the circular groove, and then the fixing block is slid into the inside of the second semicircular ring. Then, the fixing plate is inserted into one side of the fixing block after passing through the groove. This can effectively set the first and second semicircular rings inside the circular groove, which can effectively increase the surface area of the electrode body and thus improve the electrolysis efficiency to a certain extent.
[0007] Preferably, the inner walls of both the first and second semicircular rings are fixedly connected with L-shaped plates, and the L-shaped plates are slidably inserted into one side of the electrode body.
[0008] The effect achieved by the above components is that the first semicircular ring and the second semicircular ring can be connected together well by the L-shaped plate, and then the L-shaped plate can be inserted into one side of the electrode body. This allows multiple first semicircular rings and second semicircular rings to slide into the inside of the circular groove at the same time.
[0009] Preferably, a second damping rod is fixedly connected to the bottom of the electrode body, a connecting plate is fixedly connected to the bottom of the second damping rod, a second spring is sleeved on the surface of the second damping rod, one end of the second spring is fixedly connected to the bottom of the electrode body, one end of the second spring near the second damping rod is fixedly connected to the top of the connecting plate, and a fixing rod is uniformly fixedly connected to the end of the connecting plate near the second damping rod. The fixing rod is slidably inserted into the bottom of the electrode body and the bottom of the L-shaped plate.
[0010] The effect achieved by the above components is as follows: the fixing rod is inserted into the bottom of the electrode body, and then the fixing rod is inserted into the bottom of the L-shaped plate. Then, the connecting plate is pulled closer to the bottom of the electrode body by the second spring, thus effectively restricting the fixing rod to the bottom of the inner wall of the L-shaped plate, and thus effectively restricting the L-shaped plate inside the electrode body.
[0011] Preferably, a connecting groove is provided at the bottom of the electrode body, a connecting rod is fixedly connected to the inner wall of the connecting groove, a U-shaped plate is slidably sleeved on the surface of the connecting rod, and the U-shaped plate is slidably connected to the inner wall of the connecting groove.
[0012] The effect achieved by the above components is: the U-shaped plate is manually controlled to slide on the surface of the connecting rod, thereby fitting the U-shaped plate onto the surface of the connecting plate, so that the connecting plate is in close contact with the bottom of the electrode body.
[0013] Preferably, a third spring is sleeved on the surface of the connecting rod, one end of the third spring is fixedly connected to one side of the inner wall of the connecting groove, and the end of the third spring near the connecting rod is fixedly connected to one side of the U-shaped plate.
[0014] The effect achieved by the above components is that the third spring pulls the U-shaped plate closer to the second damping rod, which can effectively restrict the U-shaped plate to the surface of the connecting plate.
[0015] Preferably, the protective device includes a cylinder, the bottom of which is fixedly connected to the top of the electrode body, the cylinder is sleeved on the surface of the connecting wire, a locking groove is formed on the surface of the cylinder, a rubber sleeve is slidably sleeved on the surface of the cylinder, the rubber sleeve is sleeved inside the locking groove, and a rubber cylinder is fixedly connected to the top of the rubber sleeve, the rubber cylinder is sleeved on the surface of the connecting wire.
[0016] The effect achieved by the above components is as follows: When using the protective device, the rubber sleeve is manually placed on the surface of the cylinder, and then part of the rubber sleeve is placed inside the locking groove. This can effectively restrict the rubber cylinder on the surface of the connecting wire, which can, to a certain extent, prevent the connection between the connecting wire and the electrode body from bending and, to a certain extent, prevent the connection between the connecting wire and the electrode body from being affected.
[0017] Preferably, a protective sleeve is fixed to the bottom of the rubber cylinder, the protective sleeve is disposed inside the cylinder, and the protective sleeve is fitted over the surface of the connecting wire.
[0018] The effect achieved by the above components is that after the rubber sleeve is placed on the surface of the cylinder, the protective sleeve is placed in the middle of the cylinder and the connecting line, which to a certain extent avoids the surface of the connecting line inside the cylinder being scratched by the top of the cylinder.
[0019] Preferably, the surface of the rubber sleeve is fitted with a first fixing ring and a second fixing ring, which are disposed inside the locking groove. A fixing groove is formed on one side of the first fixing ring, and one end of the second fixing ring is slidably connected to the inner wall of the fixing groove. A sliding groove is formed on one side of the second fixing ring, and a sliding block is slidably connected to the inner wall of the sliding groove. A fourth spring is fixedly connected to one side of the inner wall of the sliding groove, and the end of the fourth spring away from the sliding groove is fixedly connected to one side of the sliding block. A notch is formed on one side of the fixing groove, and the inner wall of the notch is slidably connected to the sliding block.
[0020] The effect achieved by the above components is as follows: the first and second fixing rings are manually slid into the inside of the fixing groove, and then one end of the second fixing ring is slid into the inside of the fixing groove, so that the sliding block slides out of the sliding groove and then slides out of the fixing groove through the notch. The fourth spring presses the sliding block away from the sliding groove, thereby setting the sliding block inside the notch, thus effectively restricting the first and second fixing rings inside the locking groove. This can effectively restrict the rubber sleeve to the surface of the cylinder.
[0021] In this invention, by setting a connecting device, when using the connecting device, the first and second semicircular rings are manually slid into the inside of the circular groove, and then the fixing block is slid into the inside of the second semicircular ring. Then, the fixing plate is inserted into one side of the fixing block after passing through the groove. This can effectively set the first and second semicircular rings inside the circular groove, which can effectively increase the surface area of the electrode body and thus improve the electrolysis efficiency to a certain extent.

[0028] Example 1, as Figure 1-5 As shown, an electrode for an electrolytic cell has a connecting wire 2 fixedly connected to the top of the electrode body 1, a connecting device 3 provided on the surface of the electrode body 1, and a protective device 4 provided on the top of the electrode body 1. When using the electrolytic cell electrode, the electrode is placed in the electrolytic cell through the connecting wire 2, and the positive and negative terminals of the power supply are connected to different electrodes through different connecting wires 2, thereby enabling alkaline hydrogen electrolysis experiments.
[0029] Reference Figure 2 and Figure 3The connecting device 3 connects the first semi-circular ring 301 and the second semi-circular ring 302. Circular grooves 303 are evenly formed on the surface of the electrode body 1. Both the first semi-circular ring 301 and the second semi-circular ring 302 are located inside the circular grooves 303. A fixing block 304 is fixedly connected to one side of the first semi-circular ring 301. The fixing block 304 is slidably inserted into one side of the second semi-circular ring 302. A groove 305 is formed on one side of the second semi-circular ring 302. A fixing plate 306 is slidably inserted into the inner wall of the groove 305, and the fixing plate 306 is slidably inserted into one side of the fixing block 304. A first damping rod 307 is fixedly connected to one side of the groove 305. The end of the first damping rod 307 away from the groove 305 is fixedly connected to one side of the fixing plate 306. A sleeve is fitted on the surface of the first damping rod 307. A first spring 308 is provided, with one end of the first spring 308 fixedly connected to one side of the inner wall of the groove 305. The end of the first spring 308 near the first damping rod 307 is fixedly connected to one side of the fixing plate 306. When using the connecting device 3, the first semi-circular ring 301 and the second semi-circular ring 302 are manually slid into the inside of the circular groove 303. Then, the fixing block 304 is slid into the inside of the second semi-circular ring 302. Finally, the fixing plate 306 is inserted into one side of the fixing block 304 after passing through the groove 305. This effectively positions the first semi-circular ring 301 and the second semi-circular ring 302 inside the circular groove 303, thus increasing the surface area of the electrode body 1 and improving electrolysis efficiency to a certain extent. L-shaped plates 309 are fixedly connected to the inner walls of the semicircular rings 302. The L-shaped plates 309 are slidably inserted into one side of the electrode body 1. The L-shaped plates 309 can effectively connect the first semicircular rings 301 and the second semicircular rings 302 together. By inserting the L-shaped plates 309 into one side of the electrode body 1, multiple first semicircular rings 301 and second semicircular rings 302 can be simultaneously controlled to slide into the circular groove 303. A second damping rod 310 is fixedly connected to the bottom of the electrode body 1. A connecting plate 312 is fixedly connected to the bottom of the second damping rod 310. A second spring 311 is sleeved on the surface of the second damping rod 310. One end of the second spring 311 is fixedly connected to the bottom of the electrode body 1. The second spring 311 is positioned close to the second damping rod 310. The top of the connecting plate 312 is fixedly connected to the end of the connecting plate 312 near the second damping rod 310. Fixed rods 313 are evenly fixedly connected to one end of the connecting plate 312 near the second damping rod 310. The fixed rods 313 are slidably inserted into the bottom of the electrode body 1 and the bottom of the L-shaped plate 309. The second spring 311 then pulls the connecting plate 312 towards the bottom of the electrode body 1, effectively confining the fixed rods 313 to the bottom of the inner wall of the L-shaped plate 309, and thus effectively confining the L-shaped plate 309 inside the electrode body 1. A connecting groove 314 is provided at the bottom of the electrode body 1, and a connecting rod 316 is fixedly connected to the inner wall of the connecting groove 314.A U-shaped plate 315 is slidably fitted onto the surface of the connecting rod 316. The U-shaped plate 315 is slidably connected to the inner wall of the connecting groove 314. The U-shaped plate 315 is manually slidable on the surface of the connecting rod 316, thereby fitting onto the surface of the connecting plate 312, making the connecting plate 312 tightly against the bottom of the electrode body 1. A third spring 317 is fitted onto the surface of the connecting rod 316. One end of the third spring 317 is fixedly connected to one side of the inner wall of the connecting groove 314, and the end of the third spring 317 near the connecting rod 316 is fixedly connected to one side of the U-shaped plate 315. The third spring 317 pulls the U-shaped plate 315 towards the second damping rod 310, thus effectively confining the U-shaped plate 315 to the surface of the connecting plate 312.
[0030] Reference Figure 4 and Figure 5The protective device 4 includes a cylinder 401, the bottom of which is fixedly connected to the top of the electrode body 1. The cylinder 401 is fitted onto the surface of the connecting wire 2. A locking groove 403 is formed on the surface of the cylinder 401. A rubber sleeve 402 is slidably fitted onto the surface of the cylinder 401, and the rubber sleeve 402 is fitted inside the locking groove 403. A rubber cylinder 404 is fixedly connected to the top of the rubber sleeve 402, and the rubber cylinder 404 is fitted onto the surface of the connecting wire 2. When using the protective device 4, the rubber sleeve 402 is manually fitted onto the surface of the cylinder 401, thereby positioning part of the rubber sleeve 402 inside the locking groove 403. This effectively secures the rubber cylinder 402. 4. The rubber sleeve 402 is fixed to the surface of the connecting wire 2, which can prevent bending of the connection between the connecting wire 2 and the electrode body 1 to a certain extent, and to a certain extent avoid affecting the connection between the connecting wire 2 and the electrode body 1. A protective sleeve 405 is fixed to the bottom of the rubber cylinder 404. The protective sleeve 405 is set inside the cylinder 401 and is fitted onto the surface of the connecting wire 2. After the rubber sleeve 402 is fitted onto the surface of the cylinder 401, the protective sleeve 405 is set between the cylinder 401 and the connecting wire 2. This can prevent the surface of the connecting wire 2, which is set inside the cylinder 401, from being scratched by the top of the cylinder 401. The surface of the rubber sleeve 402 is fitted with a first A first fixing ring 406 and a second fixing ring 407 are disposed inside the locking groove 403. A fixing groove 408 is formed on one side of the first fixing ring 406. One end of the second fixing ring 407 is slidably connected to the inner wall of the fixing groove 408. A sliding groove 409 is formed on one side of the second fixing ring 407. A sliding block 410 is slidably connected to the inner wall of the sliding groove 409. A fourth spring 411 is fixedly connected to one side of the inner wall of the sliding groove 409. The end of the fourth spring 411 away from the sliding groove 409 is fixedly connected to the side of the sliding block 410. A notch 412 is formed on one side of the fixing groove 408. The inner side of the notch 412... The wall is slidably connected to the sliding block 410. The first fixing ring 406 and the second fixing ring 407 are manually slid into the inside of the fixing groove 408, and then one end of the second fixing ring 407 is slid into the inside of the fixing groove 408. After the sliding block 410 slides out of the sliding groove 409, it slides out of the fixing groove 408 through the notch 412. The fourth spring 411 presses the sliding block 410 away from the sliding groove 409, and then sets the sliding block 410 inside the notch 412. This effectively restricts the first fixing ring 406 and the second fixing ring 407 inside the locking groove 403, which can effectively restrict the rubber sleeve 402 to the surface of the cylinder 401.
[0031] Working principle: When using the electrolytic cell electrodes, the electrodes are placed in the electrolytic cell via connecting wire 2. The positive and negative terminals of the power supply are connected to different electrodes via different connecting wires 2, thus enabling alkaline hydrogen electrolysis experiments. When using the connecting device 3, the first semi-circular ring 301 and the second semi-circular ring 302 are manually slid into the circular groove 303. The L-shaped plate 309 can effectively connect the first semi-circular ring 301 and the second semi-circular ring 302 together. Then, the L-shaped plate 309 is inserted into one side of the electrode body 1. This allows multiple first semi-circular rings 301 and second semi-circular rings 302 to slide into the circular groove 303 simultaneously. Then, the fixing block 304 is slid into the second semi-circular ring 302, and then the fixing plate 306 is... After passing through the groove 305, the fixing rod 313 is inserted into one side of the fixing block 304. The fixing rod 313 is then inserted into the bottom of the electrode body 1, and subsequently into the bottom of the L-shaped plate 309. The second spring 311 pulls the connecting plate 312 closer to the bottom of the electrode body 1, effectively confining the fixing rod 313 to the bottom of the inner wall of the L-shaped plate 309. Then, the U-shaped plate 315 is manually slid on the surface of the connecting rod 316, and the third spring 317 pulls the U-shaped plate 315 closer to the second damping rod 310. This effectively confines the U-shaped plate 315 to the surface of the connecting plate 312, causing the connecting plate 312 to fit tightly against the bottom of the electrode body 1, thus effectively confining the L-shaped plate 309 inside the electrode body 1. The first semicircular ring 301 and the second semicircular ring 302 can be well positioned inside the circular groove 303, which can effectively increase the surface area of the electrode body 1 and thus improve the electrolysis efficiency to a certain extent. When using the protective device 4, the rubber sleeve 402 is manually placed on the surface of the cylinder 401, and then part of the rubber sleeve 402 is positioned inside the locking groove 403. The first fixing ring 406 and the second fixing ring 407 are manually slid into the fixing groove 408, and then one end of the second fixing ring 407 is slid into the fixing groove 408, so that the sliding block 410 slides out of the sliding groove 409 and then slides out of the fixing groove 408 through the notch 412. The fourth spring 411 presses the sliding block 410 away from the sliding groove 409 in the direction of the wind. 10. The sliding block 410 is then placed inside the notch 412, which effectively restricts the first fixing ring 406 and the second fixing ring 407 inside the slot 403. This effectively restricts the rubber sleeve 402 to the surface of the cylinder 401, and the rubber sleeve 404 to the surface of the connecting line 2. After the rubber sleeve 402 is placed on the surface of the cylinder 401, the protective sleeve 405 is placed between the cylinder 401 and the connecting line 2. This, to a certain extent, prevents the surface of the connecting line 2 inside the cylinder 401 from being scratched by the top of the cylinder 401. This, to a certain extent, prevents the connection between the connecting line 2 and the electrode body 1 from bending, and to a certain extent, prevents the connection between the connecting line 2 and the electrode body 1 from being affected.
[0032] It should be noted that all damping rods in this case are telescopic dampers, which can absorb energy during the extension and retraction process.
