Description
Technical field
The invention belongs to protective shell technical fields, and in particular to a kind of satellite communication power supply signal comprehensive electromagnetic protective shell.
Background technique
Telecommunication satellite is generally by satellite structure, power-supply system, temperature control system, posture control system, antenna system, transponder system
Deng composition；Wherein, core component one of of the power-supply system as satellite communication is mainly used for as each systems other in satellite communication
System power supply.Currently, usually power-supply system is placed in protective shell for protection power source system, it is protected using protective shell
Shield prevents extraneous interference, influences normal power supply.However, existing protective shell resistance to external shocks ability is poor, when by foreign impacts
The phenomenon that there is protective shell deformation and is damaged in Shi Jingchang, and loses defencive function, and power-supply system is smashed.
Summary of the invention
The purpose of the present invention is to provide a kind of satellite communication power supply signal comprehensive electromagnetic protective shells, to solve existing protection
Shell resistance to external shocks ability is poor, is easy impaired technical problem.
To achieve the above object, realization that the present invention adopts the following technical solutions:
Satellite communication power supply signal comprehensive electromagnetic protective shell, comprising: shell is machined with installation in the side of the shell and slits
Mouthful, lead block is installed on the installation gap, multiple fairleads, the electricity in power-supply system are machined in the lead block
Line passes through fairlead and is drawn out to hull outside, for connecting with module to be powered, powers for it；The improvement done is: described
It is welded with L-type installation folding around shell, is welded at least two hog frames, institute in the bending part of each L-type installation folding
Stating hog frame is 3-D triangle structure, and the vertical portion of the side of hog frame and L-type installation folding is welded, the bottom surface of hog frame with
The horizontal part of L-type installation folding welds, and is machined with mounting hole on the horizontal part of L-type installation folding, solid for installing shell
It is fixed；The shell includes inner shell, outer shell, the cooling layer being arranged between inner shell and outer shell, is coated in
Cushion rubber layer around outer shell, coated in the flame-retardant layer around cushion rubber layer；Wherein, pacify in the outer shell
Equipped with inlet union, outlet connection；The inlet union, outlet connection are connected to cooling layer, the input end of inlet union with go out
The outlet end of mouth connector both passes through cushion rubber layer and flame-retardant layer extends to outside, for passing through pipeline and the cooling dress of low-temperature circulating
It sets.
The beneficial effects of the present invention are:
(1) protective shell provided by the invention improves the protective shell integrally anti-external world by welding hog frame at installation folding
Impact capacity；In addition, buffering can be played when by foreign impacts by the cushion rubber layer being coated in around outer shell
Effect, to protect the power-supply system in protective shell, it is poor effectively to solve existing protective shell resistance to external shocks ability, is easily damaged
Technical problem.
(2) protective shell provided by the invention shields electromagnetism by inner shell, outer shell, two layers of shield effectiveness
It is good；In addition, cooling layer is arranged in the protective shell in protective shell, after long-play, cooling layer and low temperature are followed by hose
Ring cooling device connects, and the low-temperature circulating cooling device outside protective shell provides coolant liquid for cooling layer and cools down, and avoids power supply
Protective shell temperature increases after system long-play, reduces the service life and working efficiency of power-supply system.
