Description

Technical Field

[0001] The present invention relates to the technical field of plant diversity detection, in particular to a plant species diversity detection device. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] In the existing technology, plant species diversity is usually analyzed by staff who walk into the forest to analyze the diversity of plant species. In recent years, drones have been used to detect and analyze trees in the forest. However, in order to ensure the stability of camera rotation, most drones used for plant diversity detection currently have the camera and drone integrated. Therefore, when the camera or drone is damaged, a lot of manpower and material resources are required, affecting the staff's efficiency in detecting plant diversity. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a plant species diversity detection device, which ensures the stability of camera rotation while facilitating the disassembly and replacement of the camera, thereby improving the detection efficiency of plant diversity by staff.

[0005] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0006] A plant species diversity detection device includes a drone, wherein a support plate is provided on the top of the drone, a rotating disk is provided on the support plate, a strip groove is provided on the rotating disk, a camera is provided in the strip groove, and a pressing mechanism is provided on the top of the camera;

[0007] The pressing mechanism includes a pressing plate, a guide column, a top plate and a bolt. The bottom of the pressing plate is provided with a rectangular slot that is engaged with the top of the camera. The two sides of the pressing plate pass through the guide column. The top of the guide column is fixedly connected to the top plate. The center of the top plate is threaded with a bolt, and the bottom of the bolt is in contact with the pressing plate.

[0008] Furthermore, a spring is provided on the guide column, and the spring is provided between the pressure plate and the rotating disk.

[0009] Furthermore, an internally threaded sleeve is fixedly connected to the bottom of the top plate, and the bolt is threadedly connected to the internally threaded sleeve.

[0010] Furthermore, anti-slip grooves are provided on the outer side of the internally threaded sleeve.

[0011] Furthermore, a hand-tightening knob is fixedly connected to the top of the bolt.

[0012] Furthermore, a rotating rod is provided at the bottom of the rotating disk.

[0013] Furthermore, a circular hole is provided in the center of the support plate, and the bottom of the rotating rod passes through the circular hole.

[0014] Furthermore, a rotation drive mechanism is connected to the bottom of the rotating rod.

[0015] Furthermore, the camera is connected to the terminal so that the data of the camera can be transmitted to the terminal.

[0016] The method for using the above-mentioned plant species diversity detection device is characterized in that, before the drone flies, the bolt is rotated downward so that the rectangular slot is engaged with the top of the camera, thereby fixing the camera on the drone; when the drone is flying, the rotating disk drives the camera to rotate, thereby allowing the camera to shoot within a relatively wide range; when the drone or the camera is damaged, the rectangular slot is disengaged from the camera by rotating the bolt upward, and the camera is taken out along the strip groove.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. The present invention separates the camera from the drone, fixes the camera in a strip groove, and further secures the camera in place with a rectangular groove in a pressure plate that can move up and down. Bolts secure the pressure plate, ensuring stability during camera rotation. To disassemble the camera, simply loosen the bolts and remove it along the strip groove, ensuring a secure camera installation while facilitating easy replacement.

[0019] 2. The camera is pressed against the rotating disk by a pressing assembly. When the rotary drive mechanism is running, the rotary disk is driven to rotate, thereby causing the camera to rotate. When the drone flies near any tree, the rotary drive mechanism can rotate the camera to a certain angle, thereby expanding the camera's shooting range and avoiding the increased risk of collision between the drone and trees due to frequent movement or adjustment of the camera angle in the forest.

[0034] Example 1

[0035] A plant diversity detection device, such as Figure 1 As shown, it includes a drone 1 and a camera 2;

[0036] like Figure 2 As shown, the camera is rectangular in shape, and a support frame 3 is installed on the top of the drone body. The top of the support frame is a horizontally arranged support plate 31, and a rotating disk 32 is horizontally arranged on the upper end of the support plate. The rotating disk is rotatably connected to the support plate; a strip groove 321 is opened on the upper end of the rotating disk, and the strip groove extends horizontally from the outer wall of the rotating disk to the center of the rotating disk, and the end of the strip groove is located directly below the rectangular card slot.

[0037] The width of the strip groove is consistent with the width of the camera, so that the strip groove can be clamped on both sides of the camera.

[0038] When the staff installs the camera 2, the camera 2 is placed in the strip groove 321 and slides along the strip groove 321 toward the end of the strip groove 321. When the camera 2 moves to the end of the strip groove 321 and cannot move further, the rectangular slot 412 is just above the camera 2. The upper end of the camera 2 can be inserted into the rectangular slot 412 by lowering the pressure plate 41. The strip groove 321 is provided to position the camera 2, making it convenient for the staff to move the camera 2 to the bottom of the rectangular slot 412.

[0039] Since the width of the strip groove 321 is consistent with the width of the camera 2, it is not easy for the staff to install the camera 2 in the strip groove 321. Therefore, rounded corners 322 are provided on both sides of the strip groove 321 near the outer wall of the rotating disk 32. Under the guidance of the rounded corners 322, the camera 2 can be easily moved from the rounded corners 322 and laterally into the strip groove 321.

[0040] A pressing mechanism 4 capable of fixing the camera on the rotating disk is provided above the rotating disk; a rotation driving mechanism 5 for driving the rotating disk to rotate is provided below the supporting plate.

[0041] like Figure 3 As shown, the pressing mechanism includes a pressing plate 41 , a top plate 42 , and two guide rods 43 .

[0042] The two guide rods are vertically mounted on the rotating disk, and the top plate is horizontally mounted on the top ends of the two guide rods; two guide holes 411 are provided on the pressure plate, which is horizontally arranged between the top plate and the rotating disk, and the two guide rods are respectively inserted into the two guide holes.

[0043] In order to fix the camera, a rectangular slot 412 is provided at the lower end of the pressure plate to engage with the top of the camera. Before the drone flies, the rectangular slot is used to fix the drone; when the camera is disassembled, the pressure plate can be pulled up to remove the camera along the strip slot.

[0044] In order to prevent the rectangular slot from being separated from the camera due to the bumping of the drone, thereby causing the camera to fall off, the pressing mechanism also includes a height adjustment component 44 for adjusting the longitudinal distance between the pressing plate and the top plate.

[0045] Specifically, the height adjustment assembly includes a bolt 441, an internally threaded sleeve 442, and two springs 443;

[0046] A hand-tightening knob 4411 is provided on the top of the bolt, a vertical threaded through hole is provided on the top plate, the bolt is threadedly connected in the threaded through hole, and the hand-tightening knob is located above the top plate; the hand-tightening knob is provided to facilitate the staff to manually tighten the bolt; Figure 4 As shown, the internal threaded sleeve is threadedly connected to the bolt, and the internal threaded sleeve is located between the pressure plate and the top plate. Specifically, the internal threaded sleeve is fixedly connected to the bottom of the pressure plate; the pressure plate is further fixed by the bolt, so that the pressure plate firmly fixes the camera to prevent the rectangular slot from detaching from the camera due to the bumping of the drone, and then causing the camera to fall off.

[0047] In order to make it easier to remove the camera, two springs are installed on the two guide columns respectively. Both springs are located between the pressure plate and the rotating disk. When the bolt moves upward, the compressed spring moves up with the pressure plate, so that the top of the camera is out of the groove, making it easier for the staff to remove the camera.

[0048] Specifically, under the elastic force of the two springs 443, the pressure plate 41 can be guaranteed to always rest on the bolt 441. When the staff adjusts the height of the pressure plate 41, the staff must first loosen the internal threaded sleeve 442 to the lower end of the bolt 441. At this time, there is no contact between the internal threaded sleeve 442 and the top plate 42. When the staff rotates the hand-tightening knob 4411 clockwise, the bolt 441 can move downward along the threaded through hole 421, thereby driving the pressure plate 41 to descend along the two guide rods 43. At this time, the two springs 443 are compressed. When the staff rotates the hand-tightening knob 4411 counterclockwise, the bolt 441 can move upward along the threaded through hole 421. Under the elastic force of the two springs 443, the pressure plate 41 can move upward and always It rests on the bolt 441; when the staff fixes the camera 2 between the pressure plate 41 and the rotating disk 32, the top of the camera 2 is completely inserted into the rectangular slot 412, and the hand-tightening knob 4411 just rests on the top plate 42. At this time, the staff rotates the internal threaded sleeve 442 so that the internal threaded sleeve 442 rests on the lower end of the top plate 42, thereby locking the bolt 441 and preventing the bolt 441 from loosening; by setting the knob, the staff can rotate the bolt 441 without the aid of any tools, which is convenient for the staff's operation. By providing anti-slip grooves 4421 on the outer wall of the internal threaded sleeve 442, it is prevented from slipping when the staff rotates the internal threaded sleeve 442, which causes the internal threaded sleeve 442 to not be well locked on the lower end of the top plate 42.

[0049] like Figure 5 As shown, the lower end of the rotating disk is fixedly connected to a coaxial rotating rod 323, and a vertical circular hole 311 is opened at the center of the support plate. The rotating rod is rotatably set in the circular hole and passes through the circular hole to the bottom of the support plate.

[0050] The rotary drive mechanism 5 includes a mounting bracket 51 and a rotary drive 52 ; specifically, the rotary drive may be a motor.

[0051] The mounting bracket is mounted below the supporting plate. The rotary driver is vertically mounted on the mounting bracket. The output shaft of the rotary driver is in transmission connection with the rotating rod.

[0052] like Figure 7 As shown, the camera 2 can transmit data with the network display terminal (such as mobile phones, computers and tablets, etc.) used by the staff in a wireless connection, and the network display can recognize and retrieve the received images, that is, extract the image features, and then search and match, and finally output the results (quickly analyze the characteristics of plants and flowers, and output the category of the flowers and plants with a high accuracy, such as the "Shape and Color Identification of Flowers" APP).

[0053] Example 2

[0054] When the staff is testing the plant diversity index of a forest in a certain area, the staff first remotely operates the drone 1 to fly the drone 1 into the area to be tested, and flies the drone 1 with the camera 2 to one of the trees, trying to ensure that the lens of the camera 2 is closer to the tree. Then the camera 2 takes a picture and sends the image data of the tree to the network display. The network display analyzes the image data of the tree, thereby obtaining the type of the tree. Then the drone 1 continues to fly to another tree, and identifies the tree in the same way, thereby determining whether the detected tree is a new type or the same type. The drone 1 flies back and forth along the planned sample line or flies a sample square, thereby collecting data on the area passed by the drone 1. The number of trees in the area, as well as the types of trees, can be used to determine the diversity of trees in the sample plot. In this way, the diversity of trees in ten different sample plots in the area is collected by the detection device, and the diversity of plants in the entire forest can be determined by big data analysis. The camera 2 is pressed against the rotating disk 32 by the pressing component, and the rotating disk 32 can be driven to rotate when the rotating drive mechanism 5 is running, thereby causing the camera 2 to rotate. When the drone 1 is flying, the rotating drive mechanism 5 can rotate the camera 2 to a certain angle, thereby making the shooting range of the camera 2 wider, avoiding the drone 1 frequently shuttling through the forest or adjusting the angle of the camera 2, which increases the risk of collision between the drone 1 and trees.

[0055] The camera 2 and the drone 1 are designed as separate parts. When either the drone 1 or the camera 2 is damaged, only the damaged part needs to be replaced. Specifically, before the drone flies, the bolt is rotated downward so that the rectangular slot is engaged with the top of the camera, thereby fixing the camera on the drone. When the drone flies, the rotating disk drives the camera to rotate, thereby allowing the camera to shoot in a relatively wide range. When the drone or the camera is damaged, the rectangular slot is disengaged from the camera by rotating the bolt upward, and the camera is taken out along the strip groove.

[0056] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
