Description

Technical Field

[0001] The utility model relates to the technical field of reflection calibration equipment, in particular to a satellite remote sensor reflection calibration equipment. Background Art

[0002] Remote sensing satellites are the most effective means for quickly detecting the Earth on a global scale and play an important role in many fields such as atmospheric detection, ecological environment, climate change, and mineral resources. Quantitative measurement of the observed object is a prerequisite for ensuring the accuracy of quantitative applications of remote sensing satellite data. In order to ensure that the equipment can provide reliable data, it must be accurately calibrated, and this is where reflection calibration comes into play.

[0003] Currently, the satellite remote sensor reflection calibration equipment is installed in the northwest region. Due to the open terrain, sandstorms are frequent in the northwest region. The pot-shaped satellite remote sensor body used for satellite remote sensor reflection calibration will cause the support frame to twist due to the direct blowing of sandstorms or strong winds, which is likely to damage the satellite remote sensor reflection calibration equipment. Summary of the Utility Model

[0004] In view of the above problems, the utility model provides a satellite remote sensor reflection calibration equipment. The telescopic rod on its hinge seat is connected to the jacking reversing block through a sliding push rod. When a sandstorm or strong wind occurs, the telescopic rod extends and contracts, driving the sliding push rod to displace in the return groove of the jacking reversing block, so as to indirectly drive the satellite remote sensor body to flip and cover the surface of the cylinder. Matching the height of the lower half cylinder, on the one hand, the higher cylinder provides protection to avoid damage caused by the direct blowing of sandstorms or strong winds to the satellite remote sensor body, resulting in the distortion of the support frame, and thus achieving the protection effect of the satellite remote sensor body.

[0005] To achieve the above object, the present utility model is realized through the following technical solutions: A satellite remote sensor reflection calibration device, including a fixing frame, in which a protective cylinder is installed, a rotating base plate is connected below the fixing frame, a satellite remote sensor body is installed on the fixing frame, a plurality of side beams are arranged inside the fixing frame, locking blocks are installed on the outer walls of the side beams, a swing frame is arranged between the plurality of side beams, a plurality of fixing beams are fixed on the swing frame, and a jacking reversing block is fixed on the fixing beam; a cylinder body is arranged inside the protective cylinder, half of the cylinder body is provided with a lower exploration half cylinder, a plurality of air duct grooves are opened on both the cylinder body and the lower exploration half cylinder, a hinge seat is fixed on the inner wall of the cylinder body, a swing motor is installed on the side wall of the hinge seat, a telescopic rod is installed on the hinge seat, and a sliding push rod is fixed on the top of the telescopic rod. The sliding push rod is mainly driven by the telescopic rod to drive displacement on the jacking reversing block, thereby changing the guide of the swing frame, causing the swing angle of the satellite remote sensor body connected in front of the swing frame to change, so that the satellite remote sensor body covers the surface of the protective cylinder, achieving the protective effect on the satellite remote sensor body.

[0006] Furthermore, the swing motor is in clearance fit with the telescopic rod, the lower exploration half cylinder is lower than the cylinder body and is adapted to the swung satellite remote sensor body, the lower part of the protective cylinder is connected to the inside of the locking block, the sliding push rod is engaged in the jacking reversing block, and the jacking reversing block is provided with a return chute. The upper chute of the return chute on the jacking reversing block is longer than its lower chute, so that when the swing frame is cooperatively flipped, it can smoothly slide into the lower chute to form an internal pull, thereby driving the satellite remote sensor body to form a flip, avoiding sandstorms and strong winds blowing directly on the satellite remote sensor body and causing excessive resistance damage to the support frame behind the body.

[0007] Furthermore, the satellite remote sensor body is fixed in front of the swing frame, a plurality of connecting rods on the fixing beam are connected to the rear surface of the satellite remote sensor body, the upper part of the locking block is connected to the protective cylinder, and the lower part of the locking block is matched with the rotating base plate. One end of the fixing beam is mainly installed on the swing frame to form a connection with the swing frame, and the struts on the surface of the fixing beam are connected to the rear of the satellite remote sensor body for support, playing a role in the linkage of the fixing beam and the satellite remote sensor body when the swing frame drives.

[0008] Furthermore, a connecting plate is connected between the locking blocks, a connecting cylinder plate is fixed above the connecting plate, a rotating sleeve plate is connected below the connecting plate, the connecting cylinder plate is fixed to the bottom of the cylinder body, and the rotating sleeve plate is nested and connected with the rotating base plate. The locking block is mainly used for grounding, but when the locking block is locked by its locking rod, the rotating sleeve plate below the connecting plate can drive the connecting cylinder plate to rotate, thereby completing the azimuth adjustment of the satellite remote sensor body.

[0009] Beneficial effects

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] In the utility model, the telescopic rod on its hinge seat is connected to the lifting reversing block through the sliding push rod. When a sandstorm or strong wind occurs, the telescopic rod expands and contracts to drive the sliding push rod to displace in the return groove of the lifting reversing block, so as to indirectly drive its satellite remote sensor body and turn it over to cover the surface of the cylinder body. Matching the height of the lower half cylinder, on the one hand, the higher cylinder body provides protection to avoid the direct blowing of the sandstorm or strong wind on its satellite remote sensor body, which may cause damage to the support frame due to distortion, thereby realizing the protection effect of the satellite remote sensor body.

[0021] The working principle of the present utility model is described as follows:

[0022] In the present utility model, a plurality of side beams 11 in the fixing frame 1 are arranged at designated positions, and then the protection cylinder 2 is connected by means of the connecting cylinder plate 122 on the connecting plate 121 between the lock blocks 12. The rotating sleeve plate 123 is nested in the rotating base plate 3. Before the lock block 12 is grounded, the whole is rotated, so as to facilitate the reflection calibration work of the satellite remote sensor body 4. However, when encountering sandstorms or strong wind weather, the swing motor 27 on the hinge seat 23 in the cylinder body 21 can be triggered to change the orientation of its telescopic rod 24. Then, under the displacement of the sliding push rod 25, it is jacked up and slides in the return chute above the jacking reversing block 15, driving the swing frame 13 to turn between the side beams 11, and simultaneously turning over the satellite remote sensing body 4 into the cylinder body 21 to form a fit with the lower exploration half barrel 26.
