Embodiment Construction

[0028] The interference light elimination structure applicable to the ionospheric photometer without moving parts of the present invention will be described in detail below in conjunction with the accompanying drawings. These specific embodiments are only used to illustrate the present invention and are not intended to limit its protection scope.

[0029] see Figure 1-5 ,

[0030] A large-scale storage tank assembly guide device for a spacecraft of the present invention includes a precision guide wheel set, a tank transfer mechanism, a guide rod, a guide rod base, a motor, a driver, a distance measuring sensor, and a control system. The precision guide wheel set Installed on the star mounting plate, the precision guide wheel set is used to realize the precise guidance of the storage tank skirt contact, which can control the lateral displacement of the storage tank within 1mm during hoisting; the upper end of the storage tank transfer mechanism passes through the lower skirt o...

Abstract

The invention relates to a general assembly guiding device for spacecraft large storage tank and using controlling method. A precision guide wheel set is arranged on a star mounting plate. The upper end of a storage tank adapter mechanism is connected with a storage tank through a mounting hole on the lower skirt of the storage tank. A guide post on the top of a guide rod is inserted into a guidehole at the lower end of the storage tank adapter mechanism. The bottom of the guide rod is connected with a guide rod base. The guide rod base can realize the movement and lock of the guide rod. A control system is respectively connected with a motor, a driver and a ranging sensor. The driver is connected with the guide rod. The method can realize the whole process of storage tank installation. The method solves the problems of inconvenient observation of the storage tank matching and inconvenient control of the storage tank attitude during the installation of the small gap and long matchingstroke of the storage tank, reduces possible collision risks during the assembly process of the storage tank, and effectively improves the safety of product assembly.

Description

technical field [0001] The invention belongs to the technical field of spacecraft assembly. Specifically, the invention relates to a guide device for the assembly of a large storage tank of a spacecraft and a use control method. Background technique [0002] As an important part of the spacecraft propulsion system, the tank is very important to the spacecraft. The common assembly method of the tank is to connect the skirt of the tank itself with the star structure hole to realize the fixation of the tank. With the development and upgrading of the spacecraft, the design of the tank Continuous upgrades, larger and larger sizes, and the application of more composite material technologies and lightweight technologies have brought about greater difficulty in the final assembly process of storage tanks. For example, a newly developed storage tank of a certain type, the outer diameter of the skirt of the storage tank is about 1300mm (large size), the total length is about 3m, the h...
