Abstract
The utility model relates to a thin sheet type glass fiber reinforced plastic antenna hood for large sized ground radar. The thin sheet type glass fiber reinforced plastic antenna hood is a ball shell body made of glass materials, and the ball shell body is composed of a curved rib board block, a dome-shaped rib board block, a reinforcing rib and a foundation base, wherein, the curved face rib board block is connected into an annular shell body by bolts via the reinforcing rib, and the dome-shaped rib board block is connected with the annular shell body formed by the curved face rib board block into a ball shell body by bolts via the annular reinforcing rib. With the advantages of simple structure, low cost, firm and durable use, and long service life, the thin sheet type glass fiber reinforced plastic antenna hood can be used for antennas of 3-20 m.
Description
The utility model is a kind of fiberglass radome.
Present existing fiberglass ground radome has two kinds of structural shapes, i.e. sandwich pattern and diaphragm type metallic framework triangular structure pattern.The sandwich pattern is to be made of honeycomb and foam layer, and states such as American and Britain, method and Japan have all adopted, and also there is application in China.But this structural shape only is adapted to narrow wave band, large diameter antenna, and cost height, manufacturing process complexity, maintenance require highly, is not easy to apply; Diaphragm type metallic framework triangular structure form is suitable for wide waveband, is universal type, but its intensity low, perishable, be not durable maintenance difficult, expense height.
The purpose of this utility model is to propose a kind of, and fiberglass heavy ground-based radar radome simple in structure, cheap, robust overcomes the shortcoming that has the fiberglass radome.
Technology contents of the present utility model is, this fiberglass radome is the global shell made from glass-reinforced plastic material, and this global shell is made up of curved surface floor block, top, garden type floor block, ribs and sole plate; The curved surface floor block has on limit rib, the limit rib porose all around, and also porose on the ribs, Kong Yukong is corresponding, connects into ring-like housing by ribs with bolt between the curved surface floor block; Top, garden type floor block is connected to become global shell by ring-like ribs with the ring-like housing that bolt and curved surface floor block constitute, and form a radial rib skeleton overall structure, connection slit between the curved surface floor block is filled out with the elastic water-proof putty, telescopic soft cover fillet is arranged above, form smooth global shell, the bottom of housing is a sole plate, sole plate is made and is given with armored concrete and buries bolt, it is relative with the hole on the rib of curved surface floor block surrounding, global shell bottom to give the position of burying bolt, by bolt global shell is fixed on the sole plate, constitutes the fiberglass ground radome.
Technique effect of the present utility model is, this thin board type fiberglass heavy ground-based radar radome, owing to structurally adopted the overall structure form of metal ribs, curved surface floor block that fiberglass is made and top, garden type floor block are connected into metal bolts and are global shell, sole plate is that armored concrete is made by bolt and global shell and connected as one, not only simple in structure, cheap, and sturdy and durable, long service life.Radar antenna is used after this glass steel cage, the work of under any weather and orographic condition, all can in all weather of the year starting shooting, but reach the work of antenna normal boot-strap as the wind and thunder of high mountain area more than 10 grades.Brought very big convenience for communication and national defence, aviation etc.And this radome is convenient to maintenance and repair and long-distance transport, and any curved surface floor block damages all can be changed, repair; The production of this radome simultaneously is to adopt to paste the production moulding, and equipment is simple, technological forming is convenient, and quality guarantees easily.It is not available that these advantages are existing fiberglass radome.This radome is suitable for wide waveband in addition, and wavelength X 〉=7.5cm, length of antenna L=3～20m all can use.
