Abstract

The invention discloses a waveguide ring mold vacuum container with a concave spherical-crown gate. The waveguide ring mold vacuum container comprises a horizontal cylinder, the concave spherical-crown gate, a temperature control baseboard, a pre-tightening hand wheel, a waveguide connector, a gate-wheel-type support, a ground guide rail, a fork-shaped mechanism and a container inner guide rail, the horizontal cylinder and the openable concave spherical-crown gate form a closed space, the pre-tightening hand wheel is utilized for conducting vacuum sealing and pressing on the horizontal cylinder and the openable concave spherical-crown gate, and the waveguide connector is reserved on the gate; the gate is supported by the gate-wheel-type support and is manually pushed to move transversely to be opened and closed along the ground guide rail; the fork-shaped mechanism has the up-and-down lifting fine adjusting function, the upper part of the fork-shaped mechanism supports the temperaturecontrol baseboard and a to-be-tested test piece, one end of the fork-shaped mechanism moves transversely along the container inner guide rail through idler wheels, and the other end of the fork-shapedmechanism is detachably connected with the concave spherical-crown gate to obtain translation thrust. The large-caliber concave spherical-crown high-vacuum negative pressure tolerance gate is adopted, the weight is reduced, and the short-distance requirement for the waveguide connector of the gate to be close to the test piece on the temperature control baseboard to the greatest extent during wireless testing is met, the situation that potential safety hazards are caused by yielding and failure of the gate under the external pressure of the atmosphere, the shortest distance for transmission of electromagnetic waves can be achieved, and the position of the satellite test piece can be manually adjusted in multiple dimensions by one person.

Description

technical field [0001] The invention belongs to the technical field of spacecraft space environment simulation equipment. Specifically, the invention relates to a vacuum container system with a concave spherical crown door, which is used for spacecraft electronic products, instruments, Thermal vacuum test and low pressure discharge test of instruments, components, parts and other devices and some complete equipment. Background technique [0002] Space environment simulation The vacuum container can form a sealed space inside the container, which can isolate the external atmospheric environment of the container, thereby simulating the vacuum, cold black and low temperature environment of outer space in the sealed space, and is used for satellites, spaceships and other spacecraft for the whole star or other Ground equipment for environmental testing of components, the main structure of which is a vacuum container system. [0003] Waveguide (WAVEGUIDE), a structure used to gui...
