The beneficial effects of the utility model are: INSAR corner reflector of the present utility model is observed INSAR first, GNSS observes, leveling observation combines, only need turn a screw, the conversion that the observation of INSAR corner reflector is observed with GNSS can be carried out, turn two screws and can carry out the conversion of INSAR elevation of satellite.Turn three screws, the orientation conversion of INSAR satellite can be carried out, thus the equipment that simplifies is installed, has saved funds, improve efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model INSAR corner reflector;
Wherein, 1 is corner reflector, and 2 is height regulating rod, and 3 is transverse axis, and 4 is column, and 5 is base, and 6 is fixed leg, and 7 is groove, and 8 is GNSS connecting hole, and 9 is leveling point, and 10 is pier base.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1, INSAR corner reflector, is made up of pier base 10, base 5 and corner reflector 1, GNSS connecting hole 8, leveling point 9.Pier base 10 is reinforced concrete structure, be of a size of 500mm (diameter) * 2000mm (highly), underground foundation is 1800*1800*1200 (300) mm, the fixed leg 6 be connected with base 5 is contained at top, corner reflector 1 is the cone be made up of three thick isosceles right triangle aluminium sheets of 3mm, isosceles right triangle aluminium sheet right angle length of side 1200mm; Between aluminium sheet, there is 40mm angle bar housing junction.Corner reflector 1 is provided with Ф=15mm right angle bottom outlet and is convenient to leak and dust; Diameter Ф=360mm is highly for the circular steel plate of 12mm is base 5, on base 5 with base center for the center of circle, the circular arc of radius R=170mm arranges trisection point, be that the center of circle is used for established angle reverberator diameter Ф=16mm brill to connect open-work with trisection point, trisection point is defined as A, B, C respectively; A, B point lays high 200mm* diameter Ф=14mm column 4, and column 4 top is 20mm transverse axis 3, and transverse axis 3 connects the column 4 that AB 2 lays; C point lays the height regulating rod 2 of H type length 400mm* diameter Ф=14mm; Between A, B, C 3, the saturating groove of milling width 20mm arc length 150mm concentric circles, i.e. groove 7, connects three fixed legs 6.The central point of base 5 is provided with GNSS connecting hole 8, and connect GNSS and observe connector, below pier base 10, north side is provided with stainless steel water on schedule 9.
Corner reflector 1 profile is the tetrahedral structure of three equilateral right-angle triangle compositions, and comprise a, b, c tri-, wherein a, b are side, c is bottom surface, bottom surface answer level lay install, lean against transverse axis 3 parallel with base 5, as long as base 5 level then bottom surface level reach requirement.Utilize C point to lay H type height regulating rod and carry out pitch regulation ± 40 ° (upset is 160 °).Horizontally rotate the groove of Adjust and use width 20mm arc length 150mm, can Level tune ± 45 ° (roughly utilizing rtk or compass to carry out position angle demarcation in advance).
