Description

Technical Field

[0001] The present invention relates to a screen device, and particularly to a water-rotating and lifting screen. Background Art

[0002] Outdoor large display screens are generally fixed in position, and their shapes are either arc-shaped or hemispherical. They can only display content in a fixed direction. When used as a projection carrier, such as a moving water curtain or a fan-shaped curtain that can be used in water, the direction of the content presented is also fixed and cannot meet the requirement of presenting content within 360 degrees in all directions. Therefore, a display screen device or a projection screen device with a fixed orientation position used as a projection carrier cannot meet this requirement. Summary of the Invention

[0004] The lifting traction rope is wound around the drum and fixed at one end, and the drum is connected to the first hydraulic motor and is driven to rotate by the first hydraulic motor;

[0005] Furthermore, a second hydraulic motor is further included; the friction drive wheel is connected to the second hydraulic motor and is driven by the second hydraulic motor.

[0006] Furthermore, a screen guiding mechanism is further included. The screen guiding mechanism includes a first guiding wheel, two second guiding wheels arranged oppositely, and a guiding track; the first guiding wheel and the second guiding wheels are respectively fixed on the rotating support frame, the surface of the first guiding wheel abuts against one side surface of the guiding track, and the surface of the second guiding wheel abuts against the other side surface of the guiding track; the guiding track is arranged on both sides of the display screen; the screen guiding mechanism is provided in two groups and is arranged symmetrically left and right.

[0007] Alternatively, further, the first guide wheel and the two second guide wheels arranged oppositely are in four groups and are symmetrically arranged vertically and horizontally.

[0008] Further, the ring beams are in two groups and are arranged vertically; the ring beams are firmly connected by web members.

[0009] Further, the guide rail is a rectangular pipe, and the rectangular pipes form the peripheral frame of the display screen.

[0014] Further, the waterborne rotating and lifting screen is further provided with a lifting stop block for limiting the position when the display screen is lifted to the upper position.

[0015] The principle of the present invention is as follows: The lifting hoisting system lifts the screen chassis through the lifting wheel, and the display screen connected thereto can be lifted and lowered by the rotation ball support; the rotation system drives the rotation support frame to drive the passed-through display screen, and the display screen rotates around the rotation ball, so as to realize the actions of lifting and rotating simultaneously. The beneficial effects of the present invention are as follows: The lifting and rotating actions can be completed independently and simultaneously; the rotation support frame does not lift and lower simultaneously when the display screen is lifted and lowered, reducing the power of the lifting system and reducing energy consumption; using a hydraulic motor as the driving force, on the one hand, it is relatively environmentally friendly, and compared with using electricity as the driving force, it has relatively high safety and monitorability. On the other hand, when used in a real water area, when not needed, it can be lowered below the water surface without damaging the original ecological natural landscape above the water surface.
