[0022] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Example 1

[0024] like Figure 1-2As shown, this embodiment provides a remote sensing imaging aerial photography device for biodiversity monitoring, including a control cabin 1 and multiple wings 2, each of which is provided with blades driven to rotate by a motor. The device also includes a quick-install component 6 provided on the control cabin 1 and a remote sensing camera component 4 fixed by the quick-install component 6. The remote sensing camera component 4 is a component equipped with remote sensing equipment and camera equipment, which enables it to detect ground targets from a certain height or distance. In this embodiment, the remote sensing camera component 4 obtains remote sensing images of the protected area. The analysis software analyzes the classification of land objects and species distribution in the remote sensing images, as well as monitors and analyzes environmental changes and evolution in the ecosystem, thereby achieving comprehensive monitoring and analysis of the number and distribution of ecosystems and species.

[0025] A support and protection assembly 5 is hingedly connected to the lower end of each of the wings 2. The support and protection assembly 5 includes a support frame 51 hinged to the lower end surface of the wing 2 and a multi-stage buffer assembly provided at the front end of the support frame 51 for preventing the wing 2 from collision.

[0026] The quick-install assembly 6 includes a sealing cylinder 61 that is installed through the control cabin 1, a suction cup 66 provided at the lower end of the sealing cylinder 61 for adsorbing the remote sensing camera assembly 4, a piston rod movably inserted in the sealing cylinder 61, and a linkage connecting the support frame 51 and the piston rod.

[0027] The motor is a dual-axis motor 3, and one side of the support frame 51 is provided with a hinge seat 52 connected to the lower end of the wing 2. A support 53 is provided inside the support frame 51, and a bearing seat 54 is rotatably fitted on the support 53. A sleeve 56 is sleeved inside the bearing seat 54. The driving end of the dual-axis motor 3 that is not connected to the blade is connected to a rotating wheel 55, and a protrusion 59 is provided on the rotating wheel 55. A positioning groove 510 corresponding to the position of the protrusion 59 is opened on the inner side of the sleeve 56.

[0028] The piston rod member includes a piston block 62 that slides against the inner wall of the sealing cylinder 61 and a movable rod 63 connected to the upper end surface of the piston block 62. The upper end surface of the piston block 62 is also provided with connecting ropes 64 corresponding to the number of support and protection components 5, and the connecting ropes 64 connect the piston block 62 and the support and protection components 5. A plurality of guide wheels 65 for guiding the connecting ropes 64 are provided on the outside of the control cabin 1.

[0029] The specific application process is that when the aerial photography device is not working, it is supported by a plurality of support and protection components 5 hinged under the wings 2. In order to ensure the stability of the flight structure of the aerial photography device, the number of wings 2 is set to 4, which are distributed in a rectangular shape. When working, the support and protection components 5 hinged under the two wings 2 on the opposite sides are rotated to a horizontal state with the wings 2. The outermost side of the support and protection components 5 wraps the blades on the wings 2 that are driven by the motor to rotate, forming a protective structure. In addition, the multi-stage buffer component of the support and protection component 5 can play an effective buffering and protection role when the wings 2 encounter obstacles and collide.

[0030] During the rotation of the support and protection component 5, the position of the sleeve 56 that cooperates with the support 53 in the support frame 51 is adjusted in advance through the rotation of the bearing seat 54, so that the position of the positioning groove 510 on the sleeve 56 can correspond to the position of the protrusion 59 on the rotating wheel 55. When the support frame 51 is flipped to the bottom of the wing 2, the protrusion 59 is embedded in the positioning groove 510. Subsequently, when the aerial photography device is working, the dual-axis motor 3 drives the blades to rotate, and the dual-axis motor 3 simultaneously drives the rotating wheel 55 to rotate. The rotating wheel 55 causes the sleeve 56 to rotate relative to it through the protrusion 59, thereby ensuring the structural connectivity between the support frame 51 and the wing 2 when the aerial photography device is working.

[0031] In addition, during the rotation of the supporting protection component 5, the linkage part will be pulled to make the piston rod move upward inside the sealing cylinder 61. The lower end of the sealing cylinder 61 is connected to the suction cup part 66. When the piston rod moves upward, the suction cup part 66 generates suction. At this time, the remote sensing camera component 4 can be fixed on the suction cup part 66 to fix it on the control cabin 1.

[0032] Example 2

[0033] On the basis of Example 1, Figure 2-4 As shown, the multi-stage buffer assembly includes an arc-shaped cover 511, a secondary buffer assembly 57 connected to the support frame 51, and four primary buffer assemblies 58 arranged in a rectangular shape on the inner side of the arc-shaped cover 511. The primary buffer assembly 58 is plug-fitted with the secondary buffer assembly 57.

[0034] The primary buffer assembly 58 includes a fixed rod 581 connected to the support frame 51, a guide rail 582 provided on the fixed rod 581, a push plate 583 slidably provided on the guide rail 582, a first buffer plug rod 584 movably plugged into the front end of the fixed rod 581 and connected to the push plate 583, the front end of the fixed rod 581 is connected to a first shock-absorbing spring 585 sleeved on the outside of the first buffer plug rod 584, and the end of the first buffer plug rod 584 that is not in contact with the fixed rod 581 is connected to the inner wall of the arc cover 511 The secondary buffer assembly 57 includes a shell 571, two buffer seats 572 arranged opposite to each other in the shell 571, a second buffer rod 573 connected to the buffer seat 572, and a second shock-absorbing spring 575 sleeved on the outside of the second buffer rod 573 and connected to the buffer seat 572. A limit plate 574 is provided at the end of the second buffer rod 573 that does not contact the buffer seat 572, and a push plate 583 connected to the two first buffer rods 584 is movably extended into the shell 571 and abutted against the limit plate 574.

[0035] When the multi-stage buffer assembly is used, the cross-section of the arc cover 511 is in the shape of an arc, the upper end of which extends toward the blade to wrap a part of the blade, and the lower end extends toward the remote sensing camera assembly 4. When the side of the aerial photography device collides, the arc cover 511 resists the impact and releases the force through the first-level buffer assembly 58 and transmits the impact force to the second-level buffer assembly 57 for further buffering. Specifically, after the arc cover 511 receives the impact, it pushes the first buffer rod 584 and the fixed rod 581 to slide, and the first shock-absorbing spring 585 is compressed. , completing the first-level buffering force release. At the same time, the push plate 583 connected to the first buffering rod 584 and the shell 571 produce active displacement, and the push plate 583 extends into the shell 571 and pushes the second buffering rod 573 connected to the limit plate 574 to slide with the buffer seat 572. The second shock-absorbing spring 575 is compressed accordingly, completing further secondary buffering force release. After the multi-stage buffering assembly transmits the force release, the impact force on the arc cover 511 is fully released, thereby improving the protection effect and ensuring the stability of the aerial photography device during operation.

[0036] Example 3

[0037] like Figure 5 As shown, based on Examples 1 and 2, the control cabin 1 is provided with a main control unit and a flight control unit, the flight control unit being connected to the main control unit, which is further connected to a wireless transceiver unit, a positioning unit, and a data transmission unit. The remote sensing camera assembly 4 includes a remote sensing device and a camera device, each of which is connected to the main control unit via a data transmission unit, and is connected to a ground control station via a wireless transceiver unit. The positioning unit includes a GPS module and a Beidou positioning module. This enhances the positioning function of the drone and ensures accurate positioning.

[0038] The control station is connected to the main control unit in the control cabin 1 through a wireless transceiver unit to perform command control and measurement operations. At the same time, the camera equipment transmits the measurement data to the main control unit through data transmission. The main control unit processes the data and transmits the data to the ground control station through the wireless transceiver unit for data analysis to obtain remote sensing image data. By analyzing the classification of land objects and species distribution in the remote sensing images, as well as monitoring and analyzing the environmental changes and evolution in the ecosystem, comprehensive monitoring and analysis of the number and distribution of ecosystems and species is achieved.

[0039] The above-described embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
