[0030] The camera fixing mechanism of the drone for aerial survey and remote sensing is improved by the clamping and fixing method of the aerial survey camera 18 so as to fix aerial survey cameras of different sizes and facilitate the replacement of different aerial survey cameras for use. It can meet the actual needs of aerial survey work, brings great convenience to aerial survey work, and also has the characteristics of high clamping stability and easy disassembly and assembly.

[0031] The L-shaped first bracket 1 can be used to connect the drone with its horizontal part so that it can be suspended under the drone, and can also be used to connect the second bracket 2 with its vertical part so as to connect the clamp block so that the aerial survey camera can be suspended and installed under the drone.

[0032] The U-shaped second bracket 2 is arranged horizontally, and its side walls are located on both sides. The clamp blocks can be installed between the two side walls, so that a pair of the clamp blocks 3 are arranged opposite to each other. A pair of the clamp blocks 3 are connected to the jacket 5 through their grooves, so that a pair of jackets 5 are also arranged opposite to each other. The relatively arranged jackets 5 can conveniently clamp and fix the aerial survey camera, and jackets 5 of different sizes can be selected according to different types and sizes of aerial survey cameras.

[0033] The setting of the sliding adjustment component can control the relative position between the pair of clamps 3. On the one hand, it is convenient to adapt to aerial survey cameras of different widths and can be adjusted over a large clamping range. On the other hand, it is also convenient for the installation or disassembly of the aerial survey camera, which is achieved by moving the pair of clamps closer to or farther away from each other.

[0034] The adjustable locking member is used to fix the jacket 5 in the groove 4, so that the jacket 5 can clamp the aerial survey camera more stably, and also facilitates the quick assembly and disassembly of the jacket 5, thereby facilitating the replacement of the jacket 5 according to different aerial survey cameras.

[0035] In some embodiments, in combination Figure 3 As shown, the sliding adjustment assembly includes a first adjusting screw rod 7, a vertical plate 10 and a pair of parallel arranged horizontal plates 9, the pair of horizontal plates 9 are respectively slidably arranged to pass through the side walls of the second bracket 2, one end of the pair of horizontal plates 9 is connected to the clamping block 3, and the other end is connected to the vertical plate 10, the first adjusting screw rod 7 passes through the vertical plate 10 and the side wall and is rotatably connected to the clamping block 3, and the first adjusting screw rod 7 is threadedly connected to the side wall.

[0036] Specifically, threaded through holes 6 are penetrated on the inner walls on both sides of the second bracket 2, and the first adjusting screw rod 7 is connected to the inner threads of the threaded through holes 6. Two rectangular through holes 8 are penetrated on the inner walls on both sides of the second bracket 2, and the horizontal plate 9 is slid through the rectangular through holes 8, and one end of the horizontal plate 9 is fixed on the corresponding clamping block 3. Vertical plates 10 are provided on both sides of the second bracket 2, and the vertical plates 10 are fixed on the corresponding two horizontal plates 9. The first adjusting screw rod 7 rotates and penetrates the corresponding vertical plates 10; by twisting the first adjusting screw rod 7, the clamping block 3 can be driven to move relative to the second bracket 2. This structure is not only simple to connect, but also easy to adjust, so that it is convenient to fix aerial survey cameras of different sizes to meet the actual needs of aerial survey work.

[0037] Furthermore, a circular groove is formed on the outer side of the clamp block 3, and the end of the first adjusting screw rod 7 is rotatably mounted in the corresponding circular groove through a bearing. Through the arrangement of the circular groove and the bearing, the first adjusting screw rod 7 can be rotatably connected, so that the rotational movement of the first adjusting screw rod 7 does not interfere with the linear movement of the clamp block 3.

[0038] Furthermore, a rubber ring is provided on the inner circumference of the rectangular through hole 8, and by providing the rubber ring, the horizontal plate 9 can be limited, so that the horizontal movement of the horizontal plate 9 is more stable. A first circular hole is passed through the vertical plate 10, and the first adjusting screw rod 7 rotates and passes through the first circular hole. By providing the first circular hole, the movement of the first adjusting screw rod is limited, and the shaking or non-axial movement of the first adjusting screw rod 7 can be prevented.

[0039] Furthermore, the upper and lower outer sides of the jacket 5 are respectively provided with card slots 11, the clamping block 3 is provided with a mounting through hole at the card slot, and the adjustable locking member is arranged at the card slot and the mounting through hole.

[0040] In some embodiments, in combination Figure 4 and 5 As shown, the adjustable locking member includes a tooth plate 12 arranged in the slot 11, and a rectangular cover 13 arranged in the mounting through hole, the rectangular cover 13 is connected to the groove 4, a tooth block 14 is slidably installed in the rectangular cover 13, one end of the tooth block 14 extends into the corresponding slot 11 and meshes with the tooth plate 12, the other end of the tooth block 14 is provided with a threaded groove 16, a second adjusting screw 15 is threadedly installed in the threaded groove 16, and the other end of the second adjusting screw 15 extends out from the rectangular cover 13.

[0041] Through the above arrangement, turning the second adjusting screw 15 can drive the tooth block 14 to move, so that the tooth block 14 is engaged or disengaged with the tooth plate 12. The tooth block 14 and the tooth plate 12 can fix the jacket 5 in the engaged state, and can remove the jacket 5 from the groove 4 of the clamping block in the disengaged state. Such an arrangement facilitates quick assembly and disassembly of the jacket 5, and further facilitates replacement of the jacket 5 according to different aerial survey cameras, so that the mechanism can adapt to different aerial survey cameras.

[0042] Furthermore, both sides of the tooth block 14 are provided with limiting grooves, and limiting blocks are slidably installed in the limiting grooves, and the limiting blocks are connected to the inner wall of the rectangular cover. By providing the limiting grooves and the limiting blocks, the tooth block 14 can be limited and allowed to move in a directional manner.

[0043] A second circular hole is formed on the rectangular cover 13 so that the second adjusting screw rod 15 can pass through. The second circular hole can also be used to support and limit the second adjusting screw rod 15 .

[0044] Furthermore, a plurality of slots are provided on an inner wall of one side of the groove 4, and plug blocks are slidably installed in the slots, and the plug blocks are fixed on the corresponding jackets. By setting the slots and the plug blocks, the jacket 5 can be limited to prevent the jacket 5 from shaking.

[0045] The inner circumference of the clamping sleeve 5 is also provided with a flexible bushing. The provision of the flexible bushing can increase the friction force on the one hand, so that the mechanism can clamp the aerial survey camera more stably, and on the other hand, its flexible property can protect the aerial survey camera from being clamped and damaged.

[0046] Furthermore, the first bracket 1 is suspended and installed at the bottom of the UAV 17. The first bracket 1 is connected to the second bracket 2 through an articulated seat for adjusting the pitch of the second bracket 2. The articulated seat can be a combination of multiple pairs of connecting ear plates and articulated shafts, or a commercially available mature pitch adjustment seat can be directly selected. Through such a setting, the second bracket 2 can be connected and the pitch angle of the aerial survey camera 18 can be appropriately adjusted.

[0047] When the drone camera fixing mechanism for aerial survey and remote sensing is used, firstly, the plurality of second adjusting screw rods 15 are rotated, and the second adjusting screw rods 15 drive the tooth block 14 to slide into the corresponding rectangular cover 13, and at the same time, the tooth block 14 withdraws from the slot 11 and disengages from the tooth plate 12, so that the fixing of the jacket 5 is released, and then the jacket 5 is pulled, so that the jacket 5 is driven to slide out of the corresponding groove 4, and then the required jacket 5 is slid into the corresponding groove 4, and the plurality of second adjusting screw rods 15 are rotated in the opposite direction, so that the tooth block 14 is meshed with the tooth plate 12 again, and the jacket 5 is fixed, so that the jacket 5 is replaced; then the aerial survey camera is placed between the two clamping blocks 3, and then rotated. The two first adjusting screw rods 7 drive the first adjusting screw rods 7 to rotate and move laterally in the threaded through hole 6, so that the clamping block 3 is driven by the first adjusting screw rod 7 to slide and move laterally in the second bracket 2, and the two clamping blocks 3 approach each other. At the same time, the clamping block 3 drives the two horizontal plates 9 to slide and move laterally in the corresponding rectangular through holes 8, and the vertical plate 10 is driven by the corresponding two horizontal plates 9 to move laterally until the aerial survey camera is tightly covered by the two clamping sleeves 5 and the aerial survey camera is fixed. Through such an arrangement, it is convenient to fix aerial survey cameras of different sizes and to replace different aerial survey cameras for use, which can meet the actual needs of aerial survey work and bring great convenience to aerial survey work.

[0048] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
