The invention provides a flexible prestressed clamp for peen forming of large-scale wallboard workpieces. The flexible prestressed clamp comprises a rigid framework used for supporting, an upward and downward extrusion module used for bending the wallboard workpieces, a lifting control module used for controlling the upward and downward extrusion module, an elastic pre-bending module used for controlling the bending shapes of the wallboard workpieces and horizontal guide rails, wherein the upward and downward extrusion module, the lifting control module and the elastic pre-bending module are mounted on the rigid framework; and the rigid framework is arranged on the horizontal guide rails and moves along the horizontal guide rails. The flexible prestressed clamp has the following beneficial effects: the prestressed clamp has extremely high flexibility and universality, and is suitable for implementing elastic pre-bending in various shapes on the wallboard workpieces of various sizes; the bending shapes of the wallboard workpieces can be well controlled; the elastic prestress application is uniform and controllable; clamping and pre-bending are both convenient and labor-saving; the center heights of the workpieces can be kept unchanged in the clamping and pre-bending process; and the positioning performance of the workpieces is extremely good.

The invention discloses an air conditioning device for a water medium, comprising a device for releasing or generating antibacterial substances into water and a water and air contact device, and water containing the antibacterial substances is in contact with air in the water and air contact device, wherein water in the water and air contact device can be continuously replenished. Sterilizing air passing the water containing the antibacterial substances by using the water containing the antibacterial substances is a brand new concept; and compared with the prior art, the air conditioning device is not only more long-term effective on antibacterial effect, but also free of greatly modifying the overall structure or introducing a complex structure so as to be lower in cost, higher in practicability and very suitable for application to a humidifier and a cooling fan.
