Example Embodiment

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, which are all exemplary and are not intended to give any indication or description of the protection scope thereof.

[0021] Such as figure 1 As shown, the see-through window of the sealed cabin of the present invention includes: a bottom frame part 1, a glass 2, a pressure ring 3, a sealing ring 4, a sealing ring 5, and a fastening 6. Process the bottom frame part 1 and the glass 2, and assemble the see-through device. The bottom frame part 1 of the fluoroscopy device is provided with a sealing groove. Install the sealing ring 5 on the groove, then install the glass 2, install the sealing ring 5 on the glass 2, and finally install the pressing ring 3 on the glass 2. During the installation process Install the fastener 6 according to the design installation position of the fastener to fasten the perspective window of the sealed cabin.

Abstract

The invention discloses a sealed cabin perspective window. The sealed cabin perspective window comprises a bottom frame part, perspective glass, and sealing rings, pressing rings and fasteners respectively arranged on two sides of the perspective glass. The bottom frame part is a support which is used for fixing the cabin body and is provided with a groove. The sealing rings are arranged in two sides of the perspective glass and are pressed into the groove through the pressing rings. The fasteners are fixed to the bottom frame part through threaded holes evenly arranged on the bottom frame part. The invention also discloses a use of the sealed cabin perspective window. The sealed cabin perspective window has pressure resistance, heat resistance and high light transmittance. A test result shows that a device measurement accuracy error shown by a theodolite is within 5s. The sealed cabin perspective window satisfies the existing requirements on an installation precision of a spacecraft product.

Description

technical field [0001] The invention belongs to the technical field of industrial measurement, and in particular relates to a theodolite which utilizes a see-through device to perform measurement in a special environment such as a sealed vacuum environment, and also relates to an application of the device in the special environment. Background technique [0002] With the development of the spacecraft and the gradual implementation of the space station, the precise rendezvous and docking of the spacecraft and the accurate control of the orbit are important links in the system control. Since the operating environment of the spacecraft in orbit is different from that of the ground, there will be formations inside and outside the airtight cabin. A certain pressure difference will bring changes in the installation accuracy of some key control equipment inside and outside the cabin, such as rendezvous and docking equipment, gyro sensors, etc. Therefore, it is particularly importan...
