[0058] The present invention will now be further described with reference to the accompanying drawings and embodiments.

[0059] Example 1. As... Figures 1-5As shown, a safety movable sealing mechanism for a cleaning tank 1 includes a transverse rotating shaft 2 hinged above the rear side of the opening 11 of the cleaning tank 1. The transverse rotating shaft 2 is connected to the rear end of the cleaning tank cover 12. One end of the transverse rotating shaft 2 is fixed to a rotating rod 31 perpendicular to the transverse rotating shaft 2. The end of the rotating rod 31 away from the transverse rotating shaft 2 is hinged to a driven connecting rod 33, and the end of the driven connecting rod 33 away from the rotating rod 31 is hinged to a driving connecting rod 32. The end of the driving connecting rod 32 away from the driven connecting rod 33 is fixedly connected to the power output shaft 34 of a transversely arranged drive motor 3. The driving connecting rod 32, the driven connecting rod 33, and the rotating rod 31 are all perpendicular to the power output shaft 34 of the drive motor 3. The drive motor 3 is located behind the cleaning tank 1 and below the transverse rotating shaft 2. The length of the driving connecting rod 32 is less than the length of the driven connecting rod 33. The length of the driven connecting rod 33 is less than the length of the rotating rod 31. The length ratio of the driven link 33, the driving link 32, and the rotating link 31 is 1:1.9:2.8.

[0063] The device employs a motor-linkage structure. Since the length of the active link 32 is less than the length of the driven link 33, and the ratio of the lengths of the active link 32 and the driven link 33 is fixed, the torque requirement for the drive motor 3 is reduced. This allows for a fixed switching angle, preventing damage to the cleaning tank opening 1 and the cleaning tank cover 12 due to overtravel under any circumstances, and also preventing damage to the drive motor 3.
