DETAILED DESCRIPTION

[0024] The following will be combined with the attached embodiment of the utility model Figure 1-5 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example:

[0026] like Figures 1 to 5 As shown, the utility model discloses an electrochemical device, comprising a reaction tank 1, wherein a plurality of partitions 11 are arranged in the reaction tank 1 for isolating the reaction tank 1 into a plurality of chambers for performing electrochemical reactions.

[0027] The partitions 11 are provided with water holes 111, and an opening and closing mechanism is provided at the water holes 111. The opening and closing mechanism specifically includes a screw rod 22, a motor 21 and a water baffle 23, wherein the motor 21 is fixedly arranged on the outer wall of the reaction tank 1, the screw rod 22 is rotatably arranged in the reaction tank 1 and connected to the output end of the motor 21. In this structure, the screw rod 22 is transversely arranged in the reaction tank 1 and passes through each water hole 111 in sequence. In addition, as shown in FIG. Figure 1 and Figure 5 As shown, the water baffle 23 is slidably connected to the partition 11 at the water hole 111 of the partition 11. At the same time, the water baffle 23 is also connected to the outside of the screw rod 22 by threaded cooperation. In this structure, the side wall of the water baffle 23 is used to block the water hole 111. When the screw rod 22 rotates under the drive of the motor 21, the partition 11 forms a limit on the water baffle 23, so the water baffle 23 can slide on the screw rod 22, and thereby stick close to or away from the side wall of the partition 11.

[0028] The reaction tank 1 is provided with a group of electrode sheet pairs and a group of workpiece fixtures in the area separated by each partition 11, wherein the workpiece fixture includes a mounting frame 41, a first rubber pad 42, a second rubber pad 43 and a sliding plate 44, wherein the first rubber pad 42 is fixedly arranged on the inner side wall of the mounting frame 41, and the sliding plate 44 is slidably arranged in the mounting frame 41, and at the same time, the second rubber pad 43 is fixedly arranged on the sliding plate 44 and is located between the first rubber pad 42 and the sliding plate 44, and in addition, an elastic pusher 45 is arranged between the sliding plate 44 and the mounting frame 41, and the elastic pusher 45 is used to make the sliding plate 44 close to the first rubber pad 42. The electrode sheet pair includes a first electrode sheet 51 and a second electrode sheet 52. The first electrode sheet 51 is arranged between the first rubber pad 42 and the second rubber pad 43. The second electrode sheet 52 is fixedly arranged on the side wall of the reaction tank 1. When the workpiece (7) is installed, the sliding plate 44 is first pushed so that the workpiece 7 can be inserted between the first rubber pad 42 and the second rubber pad 43, and the first electrode sheet 51 is in contact with the workpiece 7. At this time, the sliding plate 44 is released. The sliding plate 44 will approach the first rubber pad 42 under the action of the elastic pushing member 45, so that the workpiece 7 and the first electrode sheet 51 are clamped between the first rubber pad 42 and the second rubber pad 43.

[0029] A first displacement mechanism for driving the workpiece fixture to move up and down is arranged in the reaction tank 1, and the first displacement mechanism specifically includes a connecting rod 34, a toothless gear 31, a first rack 32 and a second rack 33, wherein the connecting rod 34, the first rack 32 and the second rack 33 are all slidably arranged in the reaction tank 1 and fixedly connected to each other, and the toothless gear 31 is rotatably arranged on the side wall of the reaction tank 1 and is located between the first rack 32 and the second rack 33. In this structure, the toothless gear 31 is used to mesh with the first rack 32 and the second rack 33, and the first rack 32 and the second rack 33 are symmetrically arranged. In addition, in this structure, the connecting rod 34 is used to install the workpiece fixture.

[0030] The working principle of the structure is as follows: the toothless gear 31 will mesh with the first rack 32 or the second rack 33 during the rotation process. At this time, according to the meshing state of the toothless gear 31, the connecting rod 34 will move downward or upward, thereby driving the workpiece fixture to move up and down.

[0031] A mounting plate 61 is provided on the mounting frame 41 , and the mounting plate 61 extends upward from the upper end of the mounting frame 41 . A plurality of first threaded holes 62 are sequentially provided on the mounting plate 61 from top to bottom. A second threaded hole 63 is provided on the connecting rod 34 , and a screw is provided between the connecting rod 34 and the mounting plate 61 .

[0032] This structure can further adjust the height of the workpiece fixture, and by connecting the screw rod with the first threaded holes 62 at different heights, a height difference can be formed between the workpiece fixtures.

[0033] The structural zoning management can be achieved by setting multiple voltages, or by using a water retaining plate 23 to make the reaction pools between every two partitions 11 independent of each other to achieve insulation isolation, so there are more operable methods for zoning management.
