Embodiment Construction

[0016] In order to better understand the present invention, the content of the present invention is further explained below in conjunction with the examples, but the content of the present invention is not limited to the following examples.

[0017] Such as figure 1 , 2 As shown, a melon-shaped spherical shell of an astronomical dome comprises a melon-shaped spherical shell body, and the corresponding center angle of the melon-shaped spherical shell body is 30°-60°. Reinforcement ribs are arranged on the inner arc surface of the shell body, and shaft sleeves are fixedly arranged at both ends of the melon petal-shaped spherical shell body.

[0018] The body of the petal-shaped spherical shell is rotated and set on the base, and it needs to be turned frequently to open or close the observation port of the dome, resulting in serious wear at both ends of the petal-shaped spherical shell body. By setting the bushing, the worn bushing can be replaced regularly There is no need to ...

Abstract

The invention discloses a scalloped segment spherical shell piece for an astronomical dome. The scalloped segment spherical shell piece comprises a scalloped segment spherical shell piece body; the sphere center angle corresponding to the scalloped segment spherical shell piece body is 30 degrees to 60 degrees; reinforcing ribs are installed on the inner arc surfaces of the scalloped segment spherical shell piece body and shaft sleeves are fixedly installed at both ends of the scalloped segment spherical shell piece body; the scalloped segment spherical shell piece body is rotationally arranged on the pedestal, which requires frequent flipping to open or close the dome observation port, resulting in severe wearing of two ends of the scalloped segment spherical shell piece body; by providing shaft sleeves, the worn shaft sleeves can be replaced periodically without the need to replace the scalloped segment spherical shell piece body so as to reduce costs; the strength of the scalloped segment spherical shell piece body is improved by setting the reinforcing ribs to prevent deformation during use.

Description

technical field [0001] The invention relates to a melon petal-shaped spherical shell of an astronomical dome. Background technique [0002] At present, the astronomical dome adopts multi-valve melon petal-shaped spherical shells that are rotatably connected to the base, and the opening and closing of the windows of the dome are realized through the opening and closing of the melon-shaped spherical shells. Both ends are easy to wear, and the melon petal-shaped spherical shell has low structural strength and variability. Contents of the invention [0003] The purpose of the present invention is to provide a melon petal-shaped spherical shell of an astronomical dome, which solves the problem that both ends of the melon petal-shaped spherical shell in the prior art are easy to wear, and the structural strength of the melon-petal spherical shell is low and variable. question. [0004] In order to solve the above technical problems, the present invention adopts the following t...
