Multiple connecting ropes 12 respectively enter between two different adjacent partitions 5. The partitions 5 are evenly fixedly connected in the connecting frame 2. The roller 4 rotates to connect the partitions 5. A second motor 6 is fixedly connected to one side of the connecting frame 2. When the second motor 6 is started, it drives the screw 7 to rotate, which can move the protrusion 8 and the moving bar 9 and drive multiple connecting ropes. 12 are evenly distributed on the roller 4, the output end of the second motor 6 is fixedly connected to the screw 7, the screw 7 is threadedly connected with a protrusion 8 and the protrusion 8 is provided with several, one side of the protrusion 8 is fixedly connected to the moving bar 9, the moving bar 9 is evenly provided with an adaptation groove 10, the retraction and release of the connecting rope 12 will pass through the adaptation groove 10, and is squeezed and limited by the pressure wheel 11, the pressure wheel 11 is connected to the rotation in the adaptation groove 10, the pressure wheel 11 is in contact with the connecting rope 12, the connecting rope 12 is sleeved on the roller 4, and a mounting strip 13 is provided on one side of the connecting frame 2. The mounting strip 13 is consistent with the mounting plate 1 and is installed on the top of the stage On the shed, guide grooves 14 are evenly opened on the mounting bar 13, and a guide wheel 15 is rotatably connected in the guide groove 14 and the guide wheel 15 is in contact with the connecting rope 12. The pressure wheel 11 cooperates with the guide wheel 15 to form a dispersed guide for the connecting rope 12, and provides a turning point and disperses the stress. A rope loop is sleeved on the connecting rope 12 and a split curtain 16 is fixedly connected on both sides of the rope loop. When the connecting rope 12 is gradually wound around the roller 4, the counterweight 17 moves up, and the split curtain 16 forms a folding structure due to the gradual approach of the mounting bar 13 and the counterweight 17. The upper end of the split curtain 16 It is fixedly connected to a mounting bar 13, a counterweight 17 is fixedly connected to the bottom end of the split curtain 16, and two support plates 18 are fixedly connected to the side of the movable bar 9 away from the mounting plate 1. Cleaning rollers 19 are rotatably connected on the upper and lower sides of the support plates 18, and a brush is evenly fixedly connected to the surface of the cleaning roller 19. At the same time, a third motor (not shown in the figure, only used as a driving source) is installed on one side of the cleaning roller 19. The cleaning roller 19 is driven to rotate by the third motor and forms a rotation direction opposite to the connecting rope 12, which can clean the floating dust stuck on the surface of the connecting rope 12, and the cleaning roller 19 is in contact with the connecting rope 12.

[0018] Among them, the combing rod has a comb-like structure, which is fixedly connected to the opposite side of the two horizontal plates 20, and the horizontal plates 20 are fixedly connected to the upper and lower sides of the support plate 18. The combing rod combs the brush on the surface of the cleaning roller 19 to remove the dust on the brush.

[0019] Among them, the nozzle 23 is evenly fixedly connected to the bottom end of the hollow plate 21, the air pump 22 is fixedly connected to the upper end of the hollow plate 21, the movable bar 9 is fixedly connected to the hollow plate 21, and the hollow plate 21 is located on one side of the support plate 18. By setting the air pump 22, air is drawn from the external environment through the hollow plate 21 and the nozzle 23 to form an outward guiding airflow in the adaptation groove 10, thereby preventing dust from entering the adaptation groove 10.

[0020] Among them, the sponge block 26 is in contact with the connecting rope 12, the sponge block 26 is fixedly connected to the oil filling box 24, the sponge block 26 is located on the bottom side of the through hole 25, the through hole 25 is located on the bottom side of the oil filling box 24, and the oil filling box 24 is fixedly connected to one side of the movable bar 9.

[0021] Among them, the through hole 25 corresponds to the pressure plate 28, the pressure plate 28 is fixedly connected to the bottom end of the electric push rod 27, and the electric push rod 27 is fixedly connected in the oil filling box 24. By setting the electric push rod 27 to drive the pressure plate 28 to close the oil filling box 24, the waste of lubricating oil can be reduced.

[0022] Working principle: When the split curtain 16 needs to be retracted or extended, the first motor 3 drives the roller 4 to rotate and prompts the connecting rope 12 to be retracted or extended. The pressure wheel 11 and the guide wheel 15 provide bending guides to disperse stress, thereby improving the stability of the connecting rope 12 when moving and winding. During this process, the connecting rope 12 gradually contacts the brush on the cleaning roller 19, and prompts dust to be desorbed, and further cleans the dust through the cross plate 20 and the combing rod. The air pump 22 guides the air through the hollow plate 21 and the nozzle 23 to reduce the dust from entering the adaptation groove 10, and then the connecting rope 12 continues to move onto the roller 4, and through the squeeze contact with the sponge block 26, the lubricant adheres to the surface of the connecting rope 12, promoting the stability of the winding movement of the connecting rope 12, and then controls the electric push rod 27 to extend so that the pressure plate 28 closes the through hole 25, reducing the waste of lubricating oil.
