[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0031] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0032] Example 1 of a non-stop power switch for an electrolytic cell (hereinafter referred to as a non-stop power switch) provided by the present utility model:

[0033] like Figures 1 to 4 As shown, the non-stop power switch includes a housing 1, an operating device, a static contact 3, a moving contact 4, a static terminal 31 and a moving terminal 41.

[0034] The static contact 3 is fixedly mounted on the housing 1 and connected to a static terminal 31. The movable contact 4 is correspondingly mounted above the static contact 3 and connected to a movable terminal 41. The static terminal 31 is connected to the cathode of the electrolytic cell busbar, and the movable terminal 41 is connected to the anode of the electrolytic cell busbar. A short-circuit conductor and a short-circuit connection are connected between the static terminal 31 and the movable terminal 41. When the static contact 3 contacts the movable contact 4, a circuit is formed with the short-circuit conductor and the short-circuit connection.

[0035] like Figure 1 and Figure 2 As shown, the operating device is installed on the housing 1 and includes a power input part 25, a connecting rod 21, a first spring 22, a swing arm 23 and a transmission member 24.

[0036] The power input unit 25 controls the movement of the moving contact 4, causing the circuit to have two states: (a) the power input unit 25 drives the moving contact 4 downward, causing it to contact the stationary contact 3, at which point the circuit is in the closed state; (b) the power input unit 25 drives the moving contact 4 upward, causing it to disengage from the stationary contact 3, at which point the circuit is in the open state. When the circuit is in the closed state, the electrolytic cell's circuit is short-circuited, and the electrolytic cell stops operating. When the circuit is in the open state, the electrolytic cell is connected to the circuit and is put into operation. By controlling the closing and opening of the circuit through the power input unit 25, the electrolytic cell can be stopped or put into operation.

[0037] like Figure 1 and Figure 3As shown, three connecting rods 21 are provided, spaced apart from each other. The connecting rod 21 comprises a first segment 211 and a second segment 212, which are integrally formed. The left end of the second segment 212 is hinged to the housing 1 via a pin 213. A second chute 215 extending left and right is provided in the middle of the second segment 212, and a spring seat 217 is provided at the right end of the second segment 212. A first chute 214 extending left and right is provided at the right end of the first segment 211. Both the first and second chute 214, 215, have waist-shaped hole structures. A stopper is slidably connected to the first segment 211. The first spring 22 is sleeved on the first segment 211, with both ends of the first spring 22 abutting against the spring seat 217 and the stopper, respectively. The first spring 22 is a compression spring, ensuring that the stopper is always subjected to a force acting to the right along the axis of the first segment 211. The stopping member is a stop ring 221 , and the stop ring 221 is slidably sleeved on the first rod segment 211 along the left-right direction.

[0038] The second rod section 212 includes two side arms 216 and a bottom plate. The two side arms 216 are arranged in parallel with each other at a front-to-back interval. The bottom plate is provided at the right end of the side arms 216 to connect the two side arms 216 together. The side arms 216 and the bottom plate make the second rod section 212 have a U-shaped structure, and the bottom plate forms the above-mentioned spring seat 217.

[0039] like Figure 1 and Figure 2 As shown, the swing arm 23 includes a boss 231, a protrusion 232, and a rotating base 233. The boss 231, protrusion 232, and rotating base 233 are fixedly connected together. The rotating base 233 is located on the right side of the swing arm 23 and is hinged to the housing 1 via a second pin 234. The boss 231 is located on the left side of the rotating base 233, and the protrusion 232 is arranged perpendicular to the boss 231 and located on the upper side of the rotating base 233.

[0040] The bosses 231 are provided in pairs and spaced apart in front and back, and are arranged corresponding to the first rod segment 211. Each pair of bosses 231 has two bosses, which are respectively provided on the front and rear sides of the corresponding first rod segment 211 to limit the first rod segment 211 in the front and rear directions.

[0041] The left end of the boss 231 is hingedly connected to a first slider, which is a sliding shaft. The sliding shaft passes through multiple first sliding grooves 214 and is slidably assembled in the first sliding grooves 214. In other embodiments, the first slider can also be hingedly provided at the right end of the first rod segment 211, and the first sliding groove 214 is correspondingly provided at the left end of the boss 231.

[0042] The connecting rod 21, the swing arm 23 and the first slider form a swing guide rod mechanism. When the swing arm 23 swings upward, it can drive the connecting rod 21 to swing upward, so that the connecting rod 21 and the swing arm 23 form a horizontal straight line state; when the swing arm 23 swings downward, it can drive the connecting rod 21 to swing downward, so that the connecting rod 21 and the swing arm 23 form a V-shaped state.

[0043] The left end of the boss 231 has an arc-shaped outer contour and abuts against a stop. When the swing arm 23 swings upward or downward, the left end of the boss 231 abuts against the stop, causing the stop to slide left and right along the axis of the first rod segment 211, thereby compressing or releasing the elastic force of the first spring 22. When the connecting rod 21 and the swing arm 23 are horizontal, the first spring 22 is compressed to its limit. When the connecting rod 21 and the swing arm 23 form a V-shaped configuration, the first spring 22 applies forces to the connecting rod 21 and the swing arm 23 in the upper left and lower right directions, respectively, causing the swing arm 23 to swing downward faster, thereby increasing the swing speed of the connecting rod 21.

[0044] like Figure 1 and Figure 2 As shown, the transmission member 24 is slidably assembled on the housing 1 and arranged in a one-to-one correspondence with the connecting rod 21 , and includes a first transmission rod 241 , a second transmission rod 242 and a second spring 243 .

[0045] A second slider is hingedly connected to the upper end of the first transmission rod 241. The second slider is a sliding shaft that simultaneously passes through multiple second sliding grooves 215 and is slidably assembled within the second sliding grooves 215. In other embodiments, the second slider can also be hingedly disposed in the middle of the second rod segment 212, and correspondingly, the first sliding groove 214 is disposed at the upper end of the first transmission rod 241.

[0046] The second transmission rod 242 is disposed below the first transmission rod 241 and is slidably connected to the first transmission rod 241. The second transmission rod 242 includes a screw 242a, a transition piece 242b, and a screwing portion 242c. The screwing portion 242c is fixedly connected to the screw 242a. The transition piece 242b has a threaded hole that matches the screw 242a. The lower end of the transition piece 242b is connected to the moving contact 4. By rotating the screwing portion 242c, the length of the screw 242a extending beyond the transition piece 242b can be adjusted, thereby causing the transition piece 242b to move the moving contact 4 up and down, thereby adjusting the initial distance between the moving contact 4 and the static contact 3. This allows the non-stop switch to be adapted to different usage scenarios.

[0047] The connecting rod 21, the transmission member 24 and the second slider form a tangent mechanism. When the connecting rod 21 swings upward, it can drive the transmission rod to slide upward, and then drive the moving contact 4 to move upward; when the connecting rod 21 swings downward, it drives the transmission rod to slide downward, and then drives the moving contact 4 to move downward.

[0048] The second spring 243 is mounted between the first transmission rod 241 and the second transmission rod 242. One end of the second spring 243 abuts against the shoulder of the first transmission rod 241, and the other end abuts against the screw portion 242c of the second transmission rod 242. When the movable contact 4 slides downward to contact the stationary contact 3, the second spring 243 can buffer the pressure generated by the contact between the movable contact 4 and the stationary contact 3, thereby reducing the impact force on the non-stop switch and increasing the service life of the device.

[0049] like Figure 1-Figure 3 As shown, the power drive unit is a dial mechanism comprising an operating lever 251, a dial 252, and a stopper 253. The dial 252 is rotatably mounted on the housing 1 about its axis extending in the front-to-back direction. A slot 252a is provided on the rear side of the dial 252, located in the middle of the dial 252. The operating lever 251 is inserted into the slot 252a. The operating lever 251 is in driving connection with the power input unit 25 and can swing left and right under the power input unit 25, driving the dial 252 to rotate counterclockwise or clockwise.

[0050] The front side of the dial 252 has two stoppers 252b spaced apart from each other. The protrusion 232 is disposed on the front side of the dial 252 and located between the two stoppers 252b. Within the rotational range of the dial 252, the protrusion 232 can contact the stoppers 252b and rotate synchronously with the stoppers 252b. When the dial 252 rotates clockwise, the left stopper 252b can contact the protrusion 232 and push the protrusion 232 to rotate clockwise, thereby driving the swing arm 23 to rotate downward. When the dial 252 rotates counterclockwise, the right stopper 252b can contact the protrusion 232 and push the protrusion 232 to rotate counterclockwise, thereby driving the swing arm 23 to rotate upward.

[0051] By spacing the two push members 252b, the protrusion 232 can move between the two push members 252b. In this case, the operating lever 251 does not directly rotate the protrusion 232 during rotation, but rather has an idle stroke. This prevents the operator from accidentally touching the operating lever 251 and causing the circuit to close or open during circuit closing and opening operations, thereby reducing the possibility of accidents and lowering safety risks.

[0052] like Figure 3As shown, the limiter 253 is fixed to the housing 1. There are two limiters 253, one on each side of the protrusion 232 of the transmission arm. When the protrusion 232 rotates clockwise and contacts the right limiter 253, the right limiter 253 can stop the protrusion 232. When the protrusion 232 rotates counterclockwise and contacts the left limiter 253, the left limiter 253 can stop the protrusion 232. By providing the limiters 253 on both sides of the protrusion 232, the clockwise and counterclockwise swing amplitudes of the protrusion 232 are limited. On the one hand, it can prevent the swing arm 23 from swinging too far downward, which would cause a large impact force when the moving contact 4 contacts the static contact 3, thus reducing the service life of the device. On the other hand, it can also prevent the swing arm 23 from swinging too far upward, which would cause the moving contact 4 and the static contact 3 to separate a large distance when the circuit is opened, thus affecting the next closing time.

[0053] The working principle of the embodiment 1 of the non-stop switch provided by the utility model is as follows:

[0054] In the initial state, operating lever 251 is in a disposition state, with connecting rod 21 and swing arm 23 in a horizontal position. To perform a non-stop operation on the electrolytic cell, operating lever 251 is controlled to rotate counterclockwise, thereby rotating dial 252. When the push member 252b on dial 252 contacts the protrusion of swing arm 23, continued rotation of dial 252 drives swing arm 23 downward, thereby driving connecting rod 21 downward. At this point, connecting rod 21 and swing arm 23 form a V-shaped configuration. The first spring 22 exerts a force on swing arm 23, accelerating its downward swing. This speeds up the downward swing of connecting rod 21, accelerating the downward movement of transmission member 24, and thereby increasing the closing speed of moving contact 4 and static contact 3. This reduces the response time of contact between moving contact 4 and static contact 3, thereby reducing heat loss during the electrolytic cell shutdown process.

[0055] When it is necessary to perform the slotting operation of the electrolytic cell, the operating lever 251 is controlled to rotate clockwise, driving the swing arm 23 to rotate upward, thereby driving the connecting rod 21 to swing upward, so that the connecting rod 21 and the swing arm 23 are transformed from a V-shaped state to a horizontal state. At this time, the moving contact 4 is disengaged from the static contact 3, and the slotting operation of the electrolytic cell is realized.

[0056] Example 2 of a non-stop switch for an electrolytic cell provided by the utility model:

[0057] The difference from Example 1 is that the static terminal 31 is connected to the anode of the electrolytic cell busbar, and the dynamic terminal 41 is connected to the cathode of the electrolytic cell busbar.

[0058] Example 3 of a non-stop switch for an electrolytic cell provided by the utility model:

[0059] The difference from the first embodiment is that the number of connecting rods 21 is not limited to three, and accordingly, the number of transmission members 24 and bosses 231 is adjusted accordingly.
