Embodiment
[0023] Such as figure 1 As shown, a glass fiber reinforced plastic spherical screen body, including a spherical crown shell curtain spliced by a plurality of glass fiber reinforced plastic spherical shells, ear plates, and a grid frame downswing rod 2, and the spherical crown shell screen is rotated down through the ear plate and the grid frame. Rod 2 is connected.
[0024] The plurality of glass fiber reinforced plastic spherical shells 1 are connected by bolts 3 , and putty 5 is filled in the concave parts of the joints. The bolt 3 is a bolt that can adjust the curvature between the glass fiber reinforced plastic spherical shells. The ear plate is composed of an ear body 41 and a protrusion 42, the ear body 41 is fixedly connected with the protrusion 42, the ear body 41 is connected with the lower rotating rod 2 of the grid frame, and the protrusion 42 passes through Bolt 3 is connected with FRP spherical shell 1. The cross section of the ear body 41 is circular.
