Description

Technical Field

[0001] The present application relates to the technical field of ball screen projection, and in particular to a large ball screen structure. Background Art

[0002] Dome projection technology is an emerging display technology that breaks the limitation that the previous projection images can only be regular flat graphics. According to the different projection methods, dome projection technology can be divided into external projection and internal projection. The screen of the internal projection dome is a spherical rear projection screen. The projector placed inside the dome projects the image onto almost the entire spherical screen, and the audience can see that the entire dome is covered with images. The internal projection dome can play specially made videos as well as ordinary videos and movies.

[0003] At present, the dome screens are mainly divided into two types: hard dome screens and soft dome screens. Soft dome screens are further divided into inflatable and vacuum types. The soft dome screen has a simple structure and is easy to install, but it is greatly affected by the natural environment and is difficult to use outdoors for a long time. Due to venue and technical reasons, hard dome screens are mostly hemispherical, making it difficult to achieve a 360-degree panoramic effect. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present application aims to propose a large-scale spherical screen structure, which can achieve a 360-degree stereoscopic panoramic effect and is simple and convenient to install and maintain.

The ball screen structure is designed as a three-layer structure design of an outer layer structure, a middle layer structure and an inner layer structure, so that the ball screen structure is more stable and reliable, can resist light natural disasters, and is suitable for long-term use as an outdoor building.

[0006] Furthermore, an outer layer base is provided at the bottom of the outer layer structure, and the outer layer base is fixedly connected to the ground, thereby enhancing the stability of the outer layer structure.

[0007] Furthermore, the middle layer structure is a double-layer spherical grid, which enhances the safety and stability of the spherical curtain structure.

[0008] Furthermore, a fixed base is provided at the bottom of the middle structure, the middle structure is installed on the fixed base, and the fixed base is fixedly connected to the ground through anchor bolts and threaded steel bars.

[0009] Furthermore, four fixing parts are provided at the connection between the fixed base and the middle structure, and the four fixing parts are evenly distributed at the bottom of the middle structure, so as to support the middle structure more stably.

[0010] Furthermore, the outer ball connection mechanism is formed by welding square tubes of various specifications.

[0011] Furthermore, the inner layer structure includes a curtain board and a keel structure, the keel structure includes a plurality of transverse keels and a plurality of longitudinal keels, the plurality of transverse keels and the plurality of longitudinal keels are arranged in a crisscross pattern to form a sphere, the connection between the plurality of transverse keels and the plurality of longitudinal keels is fixed by a porous disc and fixing bolts, and the curtain board is installed on the inner side of the sphere formed by the plurality of transverse keels and the plurality of longitudinal keels, thereby forming a spherical curtain body.

[0012] Furthermore, the surfaces of the plurality of transverse keels, the plurality of longitudinal keels and the middle structure are all sprayed with metal anti-rust paint, which can effectively enhance the anti-rust ability of the dome curtain structure.
