Problems solved by technology

[0004] Aiming at the technical problem that measuring instruments such as theodolite cannot measure the equipment in the cabin under special environments such as pressurization and thermal vacuum in the sealed cabin of the spacecraft, the present invention measures the installation accuracy of the equipment in the cabin by erecting the theodolite outside the cabin and through the perspective device , the accuracy can reach within 5 seconds

Embodiment Construction

[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 provide any indication or description of its protection scope.

[0021] like figure 1 As shown, the perspective window of the sealed cabin body 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 glass 2, and assemble the see-through device. There is a sealing groove on the bottom frame part 1 of the see-through device, and the sealing ring 5 is installed on the groove, and then the glass 2 is installed, the sealing ring 5 is installed on the glass 2, and the pressure ring 3 is finally installed on the glass 2. Install the fastener 6 according to the designed installation position of the fastener, and fasten the see-through window of the sealed cabin.

[0022] like figure 2 As s...

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...
