Abstract
The utility model relates to a glass fibre reinforced plastic canopy used for showing astronomical phenomenon and performance in a planetarium. A semi-spherical reticulate cage framework is provided. A fixedly connected glass fibre reinforced plastic screen is arranged at the inner side of the reticulate cage framework. Densely covered micropores are arranged on the glass fibre reinforced plastic screen. L-shaped metal sections are back-to-back connected to bolts, so that the reticulate cage framework is made. Because the glass fibre reinforced plastic is adopted to manufacture the screen, the manufacture cost of the canopy is reduced. The manufacture is easy. The screen has the advantages of uniform radians and high precision. The utility model conforms to the operation requirements of the planetarium.
Description
The utility model relates to the projection screen technical field, is the special-purpose canopy of the heavens of projection astronomical phenomena in a kind of planetarium.
At present, the canopy of the heavens of projection astronomical phenomena performance in the planetarium, it is the shape of making the hemisphere pot, as motion picture projection on curtain, projection is on the canopy of the heavens, and the canopy of the heavens is the requisite curtain of planetarium projection astronomical phenomena performance, and the existing canopy of the heavens generally adopts aluminum alloy plate materials to manufacture curtain, its cost height, difficulty of processing are big, make precision and are difficult to guarantee.
The purpose of this utility model provides the glass canopy of the heavens that a kind of cost is low, making is easy, the curtain radian is even, precision is high.
For achieving the above object, the utility model is taked following design scheme: be provided with the netted cage skeleton of hemispherical, be provided with affixed glass fiber reinforced plastic curtain in this netted cage skeleton inboard, be provided with densely covered micropore on the glass fiber reinforced plastic curtain, described netted cage skeleton is to make with Bolt Connection by L shaped shape is back-to-back.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation
Fig. 2 is the local enlarged diagram of Fig. 1
As shown in Figure 1 and Figure 2, instructions for use according to the canopy of the heavens, be shaped on the netted cage skeleton 1 of hemispherical, be provided with affixed glass fiber reinforced plastic curtain 2 in this netted cage skeleton 1 inboard, evenly be processed with micropore 3 on glass fiber reinforced plastic curtain 2, described netted cage skeleton 1 is to be made by L shaped 5 back-to-back connections with bolt 4 of shape densely coveredly.
Owing to adopt glass fiber reinforced plastic to make curtain, make the cost of making the canopy of the heavens reduce greatly, make also being easier to, the radian of curtain is even, and the precision height meets the instructions for use of planetarium.
