Spherical crown shape cover of the present invention is the lamination layer structure being made up of exterior skin, moderate soak layer and inside panel, described Inner Mongol Skin and exterior skin use epoxy resin and glass fiber cloth to be composited and uniform spreading is set to spherical crown stratiform, the thickness of described inside panel Degree is 5mm, and the thickness of described exterior skin is 2mm, has cavity, described inside panel and outer illiteracy between described inside panel and exterior skin Moderate soak layer described in the cavity dense packing effect formed between skin.
Cavity moderate soak layer of the present invention uses polyurethane foam to make, and the heat conductivity of described polyurethane foam is not more than 0.04w/m.k, density is 40~50kg/m3
The cavity formed between inside panel of the present invention and exterior skin cavity is passed to spherical crown bottom by the spherical crown top of spherical crown shape cover Subtracting, described moderate soak layer is positioned at the thickness at spherical crown top more than or equal to be positioned at spherical crown bottom thickness 2 times.
It is flange connecting plate bottom the heavy stand of connection interface of the present invention, which is provided with connecting hole.
Hoop fiber laying is also had additional, in described hoop fiber laying on the face that inside panel of the present invention is close with described flange It is provided with the through hole corresponding with described connecting hole.
Inside panel of the present invention, moderate soak layer and exterior skin glued joint successively and are integrated.
Uniformly being laid with 6 on the lateral surface of spherical crown shape cover opening part of the present invention and connect interface, any two of which is adjacent Connect and between interface, described hinged interface is set.
Pop-up device of the present invention seals lid difference from prior art and is that pop-up device of the present invention seals lid by being set by sealing lid Be calculated as spherical crown shape and make sealing lid be hinged on launching tube flange, can freely open sealing after lid constraint relief, need not by bursting, Thus realize reusing, and seal lid and use lamination layer structure, after reasonable layout quality so that it is out-shift of gravity center is to installing Outside flange, make cover can overturn under self gravitation moment and leave, use simple reaction speed fast, MISSILE LAUNCHING will not be made Become interference, seal lid and use the inside and outside eyelid covering of fiberglass of high wave transmission rate to make cover have good wave transparent performance, use high intensity Glass fiber cloth makes inside and outside eyelid covering, inside panel is designed as the main force support structure of big rigidity, high intensity simultaneously, makes remote measurement Cover entirety has enough stiffness performances;High wave transmission rate, low thermal conductivity, low-density poly-is filled between interior exterior skin Urethane foam, makes remote measurement cover while possessing good thermal insulation property, does not affect its wave transparent performance, and lighter in weight.
Pop-up device of the present invention seals lid and has the advantage that
(1) can independently overturn after being hingedly connected to constraint relief with launching tube and open;
(2) there is good wave transparent performance and heat preservation and insulation;
(3) there is good stiffness performance, and lightweight;
(4) simple and reliable for structure, reusable.
Below in conjunction with the accompanying drawings the pop-up device sealing lid of the present invention is described further.
