Curtain leveling device for spherical curtain system

Abstract

The invention discloses a curtain leveling device for a spherical curtain system. The device comprises a ceiling spherical curtain, an interactive framework and an adjusting type air exhaust unit, theinteractive framework is a hemispherical dome support formed by constructing multiple connecting pieces and fixing pieces, and an outer curtain body and an inner curtain body of the ceiling sphericalcurtain cover the upper and lower surfaces of the interaction framework respectively, so that a hemispherical cavity structure is formed in the ceiling spherical curtain. Air between the outer curtain body and the inner curtain body is exhausted by the adjusting type air exhaust unit, so that the inner curtain body forms an outward-expansion state, and then the leveling effect of the curtain surface is maintained when the inner curtain body is in an expanded state. The spherical curtain system adopting the curtain leveling device has a better projection effect so that a better viewing experience can be provided for audience.

Description

technical field [0001] The invention relates to a ball screen system, in particular to a screen leveling device for the ball screen system. Background technique [0002] The dome screen system is a platform that uses internal projection technology to display popular science images or videos. This platform breaks the previous limitation that projected images can only be plane regular graphics. The projector inside the curtain projects the image onto almost the entire spherical screen, and the audience can have a three-dimensional surround viewing experience. [0003] The shape of the sphere in the inner projection screen is very suitable for the appearance of the cosmic celestial body, and it has great advantages in expressing the cosmic celestial body. As long as we display the images describing the celestial bodies such as planets, satellites, and the sun with this inner projection, a The vivid celestial body can vividly show the mysteries of the universe to people.

Problems solved by technology

[0005] In traditional applications, the construction of the inner ball screen is a fixed installation structure. This fixed installation method may obtain an inner ball screen with a stable structure and a flat screen surface, but the installed ball screen will cause non-removable movement during the later maintenance and management process. problems, especially for large domes with a diameter of more than 10 meters, both the fixed installation process and the post-disassembly process will be time-consuming and laborious

At present, in order to realize the detachable characteristics of the dome screen, there is a dome screen frame made of detachable hard materials. When the screen is bonded to the inner surface of the dome screen frame, an uneven screen surface will be formed at each concave-convex fulcrum, which will lead to the visual defect of image deformation when the image is projected on the screen in severe cases
