DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example:

[0022] See also Figures 1 to 3 The utility model provides a technical solution: a special effect curtain wall for film and television post-production, comprising a base 1, a frame 2 is arranged on the top of the base 1, and a curtain wall 3 is installed on the inner side of the frame 2, wherein:

[0023] The frame 2 and the curtain wall 3 are controlled to be lifted and lowered by a lifting mechanism. The frame 2 is symmetrically connected to reciprocating screw rods 11 on both sides of the curtain wall 3. The reciprocating screw rods 11 on both sides of the curtain wall 3 are driven to rotate in the same direction by an electric mechanism. A lifting frame 16 is threadedly connected to the reciprocating screw rod 11. The lifting frame 16 is fixedly connected to a connecting frame 17 near the front of the curtain wall 3.

[0024] A wiping plate 18 is provided on one side of the connecting frame 17 close to the curtain wall 3, and a dust cleaning cotton 19 is installed on one side of the wiping plate 18 close to the curtain wall 3. Guide rod grooves 20 are symmetrically penetrated on both sides of the connecting frame 17, and a guide rod 21 is fixedly connected to one side of the wiping plate 18 corresponding to the guide rod groove 20. A spring 22 is sleeved on the guide rod 21 between the wiping plate 18 and the connecting frame 17;

[0025] The screen size is increased by setting up the curtain wall 3 to facilitate the subsequent production of special effects. When the display screen of the curtain wall 3 needs to be cleaned, the reciprocating screws 11 on both sides are driven to rotate in the same direction by the electric mechanism, so that the reciprocating screws 11 drive the lifting frames 16 on both sides to reciprocate and lift synchronously, and then drive the connecting frame 17 to reciprocate and lift. The wiping plate 18 and the cleaning cotton 19 are pressed against the display screen of the curtain wall 3 through the spring 22. When the connecting frame 17 is reciprocated and lifted, the cleaning cotton 19 cleans the surface of the curtain wall 3. The cleaning structure can automatically clean the display screen of the curtain wall 3, reducing the labor intensity of the staff.

[0026] See also Figures 1 to 3 The lifting mechanism includes a bracket 4, a bracket 4 is symmetrically fixedly connected to the top of both sides of the base 1 near the frame 2, a guide groove 5 is opened on one side of the bracket 4 near the frame 2, and a guide block 6 is fixedly connected to one side of the frame 2 near the guide groove 5. A slide groove 7 is symmetrically opened on the top of the base 1, and a slider 8 is arranged in the slide groove 7. An adjusting screw 9 threadedly connected to the slider 8 is rotatably connected in the slide groove 7. A transmission rod 10 is symmetrically rotatably connected to the lower part of the frame 2 near the middle, and the end of the transmission rod 10 away from the frame 2 is rotatably connected to the top of the slider 8. There are two sections of external threads on the adjusting screw 9, and the texture directions of the two sections of the external threads of the adjusting screw 9 are opposite. When the height of the curtain wall 3 needs to be adjusted, the sliders 8 on both sides are driven to approach or move away from each other by adjusting the screw 9, thereby driving the frame 2 and the curtain wall 3 to be lifted and lowered. The guide groove 5 and the guide block 6 enable the frame 2 and the curtain wall 3 to be lifted and lowered vertically, so as to facilitate the adjustment of the height of the curtain wall 3 according to needs.

[0027] See also Figures 1 to 3 The electric mechanism includes a first reversing gear 12, and the end of the reciprocating screw rod 11 near the top of the frame 2 is fixedly connected with the first reversing gear 12. A double-axis motor 13 is installed in the middle of the top of the frame 2. A second reversing gear 14 is installed on the shaft end of the double-axis motor 13 near the first reversing gear 12. A protective cover 15 is installed on the outer side of the frame 2 near the first reversing gear 12 and the second reversing gear 14. When the double-axis motor 13 is working, it drives the second reversing gear 14 to rotate. The second reversing gear 14 drives the first reversing gear 12 to rotate through meshing, so that the first reversing gear 12 drives the reciprocating screw rod 11 to rotate. Through the second reversing gear 14 set in the same direction on both sides, the reciprocating screw rods 11 on both sides can be driven to rotate in the same direction at the same time, so as to control the lifting and lowering of the cleaning structure. The guide rod 21 is a cylinder, and the outer diameter of the guide rod 21 coincides with the inner diameter of the guide rod groove 20.

[0028] Working principle: The special effects curtain wall for film and television post-production increases the screen size by setting the curtain wall 3 to facilitate the subsequent production of special effects. When the display screen of the curtain wall 3 needs to be cleaned, the reciprocating screws 11 on both sides are driven to rotate in the same direction by the electric mechanism, so that the reciprocating screws 11 drive the lifting frames 16 on both sides to reciprocate and lift synchronously, thereby driving the connecting frame 17 to reciprocate and lift. The wiping plate 18 and the cleaning cotton 19 are pressed against the display screen of the curtain wall 3 through the spring 22. When the connecting frame 17 is reciprocated and lifted, the cleaning cotton 19 cleans the surface of the curtain wall 3. The cleaning structure can automatically clean the display screen of the curtain wall 3, reducing the labor intensity of the staff;

[0029] When the height of the curtain wall 3 needs to be adjusted, the sliders 8 on both sides are driven to move closer or farther away from each other by adjusting the screw rod 9, thereby driving the frame 2 and the curtain wall 3 to rise and fall. The frame 2 and the curtain wall 3 can be lifted and lowered vertically through the guide groove 5 and the guide block 6, so as to facilitate the adjustment of the height of the curtain wall 3 according to needs. When the dual-axis motor 13 is working, it drives the second reversing gear 14 to rotate. The second reversing gear 14 drives the first reversing gear 12 to rotate through meshing, so that the first reversing gear 12 drives the reciprocating screw rod 11 to rotate. Through the second reversing gear 14 set in the same direction on both sides, the reciprocating screw rods 11 on both sides can be driven to rotate in the same direction at the same time, so as to control the lifting and lowering of the cleaning structure.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
