Description

Technical Field

[0001] The utility model relates to the technical field of radar reflectors, and particularly relates to a spaceborne corner reflector. Background Art

[0002] The common artificial corner reflector shapes mainly include the following: dihedral corner reflector and trihedral corner reflector. Among them, the trihedral corner reflector can be further divided into those with a single-sided shape of triangular pyramid, cube, etc. Because of the regular geometric shape, this kind of corner reflector utilizes the corner reflection effect to form a very strong echo signal after several reflections of the received radar beam.

[0003] Most of the existing corner reflectors are fixedly installed on the ground. Although this method is very stable and can resist wind, its disadvantage is that it is not adjustable. When the angle needs to be adjusted, the corner reflector needs to be reinstalled, which is very complicated.

[0004] Therefore, we propose a spaceborne corner reflector. Summary of the Invention

[0005] In view of the above deficiencies of the prior art, the utility model provides a spaceborne corner reflector.

[0006] To achieve the above invention purpose, the technical solution adopted by the utility model is as follows:

[0007] A spaceborne corner reflector includes: a corner reflector body; a lifting frame fixedly installed on the ground for adjusting the height of the corner reflector body; a rotating assembly installed on the top of the lifting frame for adjusting the azimuth of the corner reflector body; a flipping assembly fixedly installed on the rotating assembly, with the corner reflector body installed on the flipping assembly, and the flipping assembly is used for adjusting the inclination angle of the corner reflector body.

[0008] By setting the lifting frame, rotating assembly and flipping assembly, the height, azimuth and inclination angle of the corner reflector can be adjusted respectively. The height adjustment can avoid being blocked by vegetation in areas with rich vegetation, thus affecting the effect. The adjustment of the azimuth and inclination angle can make the adjustment of the corner reflector more flexible, without removing and reinstalling the corner reflector, saving more manpower and being more convenient to use.

[0009] Further defined, the lifting frame includes a hollow outer rod, an inner rod and a mounting plate. The inner rod is inserted into the outer rod, the mounting plate is horizontally arranged at the top of the inner rod, a locking hole penetrating through to the inner rod is opened on the rod wall at the top of the outer rod, and a locking pin is threadedly connected in the locking hole; the height adjustment is realized by the outer rod and the inner rod, the structure is simple, and the inner rod is locked after adjustment by tightening the locking pin, which is very stable.

[0010] Further limitation: The rotating assembly includes a rotating reduction gear, a rotating gear, and a rotating motor. The rotating reduction gear is rotatably connected to the mounting plate through a rotating shaft. The rotating motor is vertically mounted at the bottom of the mounting plate, and its output shaft passes through the mounting plate. The rotating gear is fixedly arranged on the output shaft of the rotating motor and meshes with the rotating reduction gear. By driving the rotating gear to rotate with the rotating motor, the rotating gear drives the rotating reduction gear to rotate, thereby realizing the rotational adjustment of the mounting device, which is convenient to operate.

[0011] Further limitation: The flipping assembly includes a flipping bracket, a flipping motor, a flipping gear, and a flipping reduction gear. The flipping bracket is in the shape of "「". The vertical section of the flipping bracket is fixedly arranged at the center position of the gear surface of the rotating gear. A space for installing the flipping gear and the flipping reduction gear is provided inside the horizontal section of the flipping bracket. The flipping motor is horizontally mounted on the outer wall of the horizontal section of the flipping bracket, and its output shaft passes through the outer wall of the horizontal section of the flipping bracket. The flipping gear is fixedly arranged on the output shaft of the flipping motor. The corner reflector body is fixedly arranged on the outer periphery of the flipping reduction gear. The flipping reduction gear is arranged on the horizontal section of the flipping bracket through a rotating shaft and meshes with the flipping gear.

[0012] By fixing the flipping motor on the horizontal section of the flipping bracket, when the flipping motor starts, the output shaft drives the flipping gear to rotate. The flipping gear drives the flipping reduction gear to rotate. The flipping reduction gear is fixedly connected to the corner reflector body. The rotation of the flipping reduction gear drives the corner reflector body to realize the adjustment of the inclination angle. The structure is simple and the operation is convenient.

[0013] Further limitation: An inclined reinforcing rod is arranged on the flipping bracket. The two ends of the reinforcing rod are respectively connected to the horizontal section and the vertical section of the flipping bracket. By arranging the reinforcing rod, the strength of the flipping bracket can be improved, and the flipping bracket can be prevented from deforming due to the weight of the corner reflector body.

[0014] Further limitation: The bottom end of the outer rod is fixedly connected to a counterweight block, and an insertion rod is arranged at the bottom of the counterweight block. By arranging the counterweight block, the overall weight of the device can be increased, and the installation can be more stable. Arranging the insertion rod at the bottom of the counterweight block can also increase the depth of the device inserted into the soil and improve the stability after installation.

[0015] Further limitation: Both the counterweight block and the insertion rod are formed by concrete casting. An anti-disengagement structure is arranged at the bottom end of the outer rod. The anti-disengagement structure is in the shape of an "I" and is arranged inside the counterweight block. Using the concrete casting structure for the counterweight block and the insertion rod is more stable, and arranging the anti-disengagement structure at the bottom of the outer rod can effectively prevent the outer rod from disengaging from the counterweight block.

[0016] The beneficial effects of the present utility model are as follows: By providing a lifting frame, a rotating assembly and a flipping assembly, more diverse adjustments can be achieved for the corner reflector, enabling it to adapt to various reflection requirements with a single installation, avoiding repeated installations for adjustment, and making it simpler and more convenient to use.
