When the lifting frame 13 is in a horizontal state, the LED screen group is in a folded state in the waterproof groove 12, and because the opening of the waterproof groove 12 is exposed above the water surface W, water cannot enter the waterproof groove 12, the waterproof groove 12 plays a role in protecting the LED screen group, and the phenomenon that the LED screen group is soaked by water to generate short circuit and the like is prevented.
When the LED screen is required to be used, the driving mechanism drives the lifting frame 13 to swing relative to the base 11, so that the lifting frame 13 rotates around the hinge joint of the lifting frame 13 and the base 11, and the lifting frame 13 is converted from a horizontal state to a vertical state. When the lifting frame 13 is in a vertical state, the rope winding and unwinding device 32 is started, the rope winding and unwinding device 32 pulls the rope 31, so that one end, connected with the LED screen group, of the rope 31 moves upwards along the lifting frame 13, the top of the LED screen group gradually moves towards the top of the lifting frame 13, and in the moving process of the LED screen group, the adjacent LED display screens 41 gradually rotate around the hinging positions of the adjacent LED display screens, so that the LED screen group is gradually converted into an unfolding state from a folding state.

Meanwhile, as the LED display screen is used in the LED screen lifting device provided by the embodiment of the invention and the LED imaging technology is adopted, the service life of the LED light source is longer than hundred thousand hours, and the running power consumption is generally less than 40 kilowatt hours, the LED screen lifting device provided by the embodiment of the invention is more attractive, energy-saving, stable and efficient, and meanwhile, the minimum influence on landscapes is achieved.
For convenience of description, one end of the lifting frame 13 hinged to the base 11 is referred to as a hinged end, and the other end opposite to the hinged end is referred to as a free end, and when the lifting frame 13 is in a vertical state, the free end is located above the hinged end. In specific implementation, the rope winding and unwinding device 32 may be mounted at a free end of the lifting frame 13, so one end of the rope 31 is connected with the rope winding and unwinding device 32, the other end is connected with the LED screen group, the rope 31 extends along a length direction of the lifting frame 13, when the rope winding and unwinding device 32 retracts the rope 31, a length of the rope 31 between the rope winding and unwinding device 32 and the LED screen group becomes shorter, therefore, the LED display screen 41 connected with the rope 31 of the LED screen group moves along the length direction of the lifting frame 13 towards a direction close to the rope winding and unwinding device 32, when the lifting frame 13 is in a vertical state, the LED display screen 41 connected with the rope 31 moves upwards, so as to drive the LED display screen 41 hinged with the rope to move upwards, and in a moving process, the LED screen group originally in a folded state is gradually unfolded.
Because when the rope winding and unwinding device 32 is disposed at the free end of the lifting frame 13, if the lifting frame 13 is in a horizontal state, the rope winding and unwinding device 32 is located below the water surface W along with the lifting frame 13, in order to avoid corrosion of the rope winding and unwinding device 32 by lake water, preferably, the rope winding and unwinding device 32 is disposed in the waterproof tank 12, the lifting frame 13 is provided with a pulley block, and the rope winding and unwinding device 32 adjusts the winding and unwinding direction of the rope 31 through the cooperation of the pulley block, so that the moving direction of the LED screen group is controlled through winding and unwinding the rope 31.

The rope reel 32 is placed in the waterproof tank 12 in a side area opposite to the fifth sheave 55. One end of the rope 31 extends from the rope winding and unwinding device 32, and then sequentially winds around the fifth pulley 55, the fourth pulley 54, the third pulley 53, the second pulley 52 and the first pulley 51, and is connected to the uppermost LED display screen 41 when the LED screen group is in a folded state.
