DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0026] Reference Figures 1-7 ​​The adjustable support type hyperspectral remote sensing survey device provided by the embodiment comprises a middle shaft rod 1, a hyperspectral instrument 3 is detachably connected to the top of the middle shaft rod 1 through a holder 2, a support leg 4 is hingedly connected to the side of the holder 2 through a hinge base, and the support leg 4 is unfolded at different angles through a support assembly 5 in the form of an umbrella rib on the middle shaft rod 1; the support assembly 5 comprises a shaft sleeve 51 capable of moving in the axial direction of the middle shaft rod 1, a support rod 52 corresponding to the support leg 4 is hingedly connected to the shaft sleeve 51, and the end of the support rod 52 away from the shaft sleeve 51 is hingedly connected to the support leg 4; and a positioning bolt 53 perpendicular to the axis of the shaft sleeve 51 is arranged on the shaft sleeve 51, and at least two positioning holes 11 matched with the positioning bolt 53 are formed in the middle shaft rod 1.

[0027] In the utility model, when the hyperspectral remote sensing survey device is used, the hyperspectral instrument 3 is connected to the holder 2 on the top of the middle shaft rod 1 through a bolt fastener, the shaft sleeve 51 can move in the axial direction of the middle shaft rod 1, when the shaft sleeve 51 moves, the support rod 52 hingedly connected to the shaft sleeve 51 will move accordingly, since the other end of the support rod 52 is hingedly connected to the support leg 4, according to the principle of a lever and a hinge structure, the movement of the support rod 52 drives the support leg 4 to rotate around the hinge base on the holder 2, the support leg 4 is unfolded at different angles, when the shaft sleeve 51 moves upwards, the support rod 52 will push the support leg 4 to unfold at a larger angle, when the shaft sleeve 51 moves downwards, the support leg 4 is folded inwards, when the shaft sleeve 51 moves to a suitable position and the support leg 4 reaches the required angle, the positioning bolt 53 is screwed tightly, the positioning bolt 53 is inserted into the corresponding positioning hole 11 in the middle shaft rod 1, the movement of the shaft sleeve 51 is limited, and thus the angle of the support leg 4 is fixed, after the support leg 4 is unfolded, the support leg 4 is placed at the survey site, and survey work can be performed;

[0028] It should be noted that since the lifting of the shaft sleeve 51 can adjust the unfolding angle of the support leg 4, when the unfolding angle of the support leg 4 becomes smaller, the hyperspectral instrument 3 on the holder 2 can be lifted, and when the unfolding angle of the support leg 4 becomes larger, the hyperspectral instrument 3 on the holder 2 can be lowered, and thus the height of the hyperspectral instrument 3 is adjusted, in addition, the hyperspectral instrument 3 is prior art, and thus the principle is not described herein.

[0029] Specifically, as shown in Figure 1 and Figure 2 The bottom of the support leg 4 is provided with a supporting leg mechanism 6 capable of switching states according to different survey requirements, the supporting leg mechanism 6 comprises a support 61 detachably installed at the bottom of the support leg 4, an axle base 62 is rotatably connected to the support 61, and a universal wheel 64 and a supporting leg 65 are arranged on the axle base 62 through two coaxial connecting pieces 63, respectively.

[0030] The shaft seat 62 is in a hollow cylindrical structure, and its two ends are movably connected with the support 61 through connecting end heads. When the shaft seat 62 rotates, the universal wheel 64 and the foot support 65 also rotate, so as to realize the switching of the foot support mechanism 6 between different states. When the hyperspectral remote sensing device needs to be moved, the universal wheel 64 can be rotated to the downward position, and the rolling characteristics of the universal wheel 64 are utilized to facilitate the movement of the device between different locations. When stable surveying is needed, the foot support 65 is rotated to the downward position, so that the foot support 65 contacts the ground and provides stable support for the device.

[0031] Specifically, as shown in Figures 2-5 The shaft seat 62 is provided with a limiting assembly 66 for positioning. The limiting assembly 66 includes a connecting shaft 661 coaxially arranged with the shaft seat 62. One end of the connecting shaft 661 extending into the shaft seat 62 is provided with a limiting plate 662, and a spring 663 is arranged between the limiting plate 662 and the inner wall of the shaft seat 62. A clamping strip 664 is further arranged on the connecting shaft 661. The support 61 is provided with a limiting groove 611 which cooperates with the clamping strip 664.

[0032] The connecting shaft 661 penetrates one of the connecting end heads of the shaft seat 62 and is movably connected therewith. When the universal wheel 64 or the foot support 65 needs to be switched, the pull ring on the connecting shaft 661 is pulled outward along the axis direction of the shaft seat 62. The connecting shaft 661 drives the limiting plate 662 to move and compresses the spring 663. At this time, the clamping strip 664 on the connecting shaft 661 is separated from the limiting groove 611 of the support 61, and one end of the clamping strip 664 is still clamped in the slot of one of the connecting end heads of the shaft seat 62. At this time, the connecting shaft 661 is rotated by using the pull ring, so that the connecting shaft 661 drives the shaft seat 62 to rotate by 180°, thereby switching the universal wheel 64 or the foot support 65. After the switching is completed, the pull ring is released, the connecting shaft 661 is reset under the action of the spring 663, and the clamping strip 664 on the connecting shaft 661 is clamped in the limiting groove 611 of the support 61. The clamping strip 664 cooperates with the limiting groove 611 to limit the further rotation of the connecting shaft 661 and the shaft seat 62, thereby realizing the positioning of the shaft seat 62 and ensuring that the universal wheel 64 or the foot support 65 is in a stable working state and cannot be rotated at will.

[0033] It should be noted that the connecting piece 63 comprises a mounting sleeve 631 connected with the shaft seat 62, an open end of the mounting sleeve 631 is sleeved with a mounting rod 632, and the inside of the mounting sleeve 631 is provided with a damping pad 633. The damping pad 633 arranged in the inside of the mounting sleeve 631 will generate a damping force on the movement of the mounting rod 632 in the mounting sleeve 631. When the universal wheel 64 or the foot support 65 is subjected to external force and rotates or shakes, the damping pad 633 will hinder the movement of the mounting rod 632 in the mounting sleeve 631, so that the movement of the universal wheel 64 and the foot support 65 is more stable, unnecessary shaking and vibration are reduced, and the stability of the surveying device during use is improved.

[0034] In addition, the foot support 65 comprises a fixed rod arranged perpendicularly with the supporting leg 4, and the outside of the fixed rod is wrapped with an anti-skid sleeve. The fixed rod of the foot support 65 is arranged perpendicularly with the supporting leg 4, so that when the device is in a supporting state, the foot support 65 can be maximally contacted with the ground, the weight of the device is evenly transmitted to the ground, the stability of the vertical structure is utilized to enhance the supporting effect of the whole device, and the material characteristics of the anti-skid sleeve are utilized to increase the friction between the device and the ground. When the device is placed on the ground, the anti-skid sleeve is tightly contacted with the ground, the friction coefficient is increased, so that the device can be kept stable on the ground with various materials and conditions and is not easy to slide or shift.

[0035] The above is only a preferred specific implementation of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art, according to the technical scheme and the inventive concept of the present application, can make equivalent replacement or change within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
