When surveying the quadrat to be tested, it is necessary to manually enter the quadrat to set up the pull-out square frame. The framed part is the quadrat to be tested. After the frame is set up, the quadrat to be tested is delineated. Then, a photographic device is used to photograph and sample the delineated quadrat. When dealing with some special quadrat that cannot be entered by people, there are problems of inconvenience and low efficiency. Utility Model Content

[0003] This invention provides a plant community quadrat survey device to overcome the inconvenience of operation of such devices.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] The plant community quadrat survey device is characterized by comprising a main pole, a movable imaging device located at the upper end of the main pole, and a boundary positioning rod group located at the lower end of the main pole for placing on the ground to delineate the quadrat boundary, wherein the boundary positioning rod group includes two boundary telescopic rods that can extend outward.

[0006] As described above, in the plant community quadrat survey device, the boundary positioning rod assembly includes a movable sleeve for fitting onto the main rod and a locking member for locking or unlocking the movable sleeve on the main rod, and the two boundary telescopic rods are connected to the movable sleeve.

[0007] In the plant community quadrat survey device described above, the boundary telescopic rod is hinged to the movable sleeve via a connecting structure.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 6 The plant community quadrat survey device shown is characterized by comprising a main pole 1, a movable imaging device 11 located at the upper end of the main pole 1, and a boundary positioning rod assembly 12 located at the lower end of the main pole 1 for placing on the ground to delineate the quadrat boundaries. The boundary positioning rod assembly 12 includes two outwardly extending boundary telescopic rods 121. Figure 4 As shown, the boundary telescopic rod 121 is equipped with a scale 1211. The scale 1211 is calibrated according to the specific length of the boundary telescopic rod 121. Each section of the boundary telescopic rod 121 can be set to 20 cm, 50 cm, or other lengths depending on the different characteristics of the sample plot to be measured and the application scenario. Correspondingly, the number of sections of the boundary telescopic rod 121 can also be adjusted. The scale 1211 can be marked every 1 cm, 5 cm, 10 cm, or as needed. When delineating the sample plot to be measured, only the corresponding number of sections of the boundary telescopic rod 121 need to be pulled out to complete the delineation. The operation is simple and convenient, and no personnel need to enter the sample plot to be measured. This can prevent damage to special sample plots and can also make delineation measurement and investigation more convenient and safer in complex terrain.

[0026] Furthermore, such as Figure 1 and Figure 2As shown, the boundary positioning rod assembly 12 includes a movable sleeve 122 for fitting onto the main rod 1 and a locking member 123 for locking or unlocking the movable sleeve 122 on the main rod 1. The two boundary telescopic rods 121 are connected to the movable sleeve 122. The movable sleeve 122, in conjunction with the locking member 123, allows the boundary telescopic rods 121 to be adjusted in position, enabling the movable sleeve 122 to move the boundary telescopic rods 121 in the height direction of the support rod. The locking member 123 can be a locking screw with a hand-tightening component, a fastener, or a snap-fit ​​component consisting of the main rod 1 and the movable sleeve 122. When the user conducts a field survey, the movable sleeve 122 can be moved to the desired position, and then the locking member 123 can be locked to fix the movable sleeve 122 at the required survey height, thus positioning the boundary telescopic rods 121 in the appropriate position. The operation is simple and facilitates the conduct of surveys.

[0027] Furthermore, such as Figure 3 As shown, the boundary telescopic rod 121 is hinged to the movable sleeve 122 via a connecting structure 13. The connecting structure 13 includes an ear plate 131 on the movable sleeve 122, a connecting plate 132 on the boundary telescopic rod 121, and a pin 133 connecting the ear plate 131 and the connecting plate 132. The connecting structure 13 allows the boundary telescopic rod 121 to rotate. Besides the described structure of the ear plate 131 engaging with the pin 133 and the connecting plate 132, the connecting structure 13 can also be configured as a rotating joint mechanism or other types of structures. The detachable and rotatable connecting structure 13 makes using the boundary telescopic rod 121 more convenient.

[0028] Furthermore, such as Figure 1 and Figure 2 As shown, the main rod 1 is provided with a latch 14 for receiving the boundary telescopic rod 121 when it rotates close to the main rod 1. The telescopic rod 21 is received in the following state: Figure 2 As shown. The card 14, except... Figures 1 to 2 Besides the shape shown, the storage slot can also be configured as a triangular, square, or polygonal shape, and the shape of the boundary telescopic rod 121 can be changed accordingly. The two work together to securely store the boundary telescopic rod 121. The design of the boundary telescopic rod 121 makes it easier to store, and prevents it from breaking or deforming due to shaking when the entire device is folded up, thus making the entire device more portable and easier to operate.

[0029] Furthermore, such as Figure 6As shown, the upper end of the main rod 1 is provided with a support rod 111 that can extend and retract relative to the main rod 1. The upper end of the support rod 111 is hinged to one end of the flip connector 112, and the other end of the flip connector 112 is hinged to the shooting device 11. Both the hinge portion of the main rod 1 and the flip connector 112 and the hinge portion of the shooting device 11 and the flip connector 112 are provided with damping mechanisms. The damping structure can improve the stability of the support rod 111. The shooting device 11 can adjust the shooting angle through the flip connector 112. When defining the range, the shooting device 11 only needs to be focused so that the two mutually perpendicular sides of the captured image close to the device coincide with the boundary telescopic rod 121. The captured image of the shooting device 11 is set to square. This telescopic and bendable design makes the shooting device 11 more portable and makes the range definition more convenient.

[0030] Furthermore, such as Figure 6 As shown, the movable shooting device 11 at the upper end of the main rod 1 is connected to a telescopic support rod 111. The support rod 111 is equipped with a universal connector 112, allowing the shooting device 11 to adjust its shooting angle via the universal connector 112. The support rod 111 can be extended and retracted along the length of the main rod 1. When defining a range, the shooting device 11 only needs to be focused so that the two perpendicular sides of the captured image align with the boundary telescopic rod 121. The captured image of the shooting device 11 is set to a square. This telescopic and bendable design makes the shooting device 11 more portable and facilitates range definition.

[0031] Furthermore, such as Figure 1 and Figure 2 As shown, when the two boundary telescopic rods 121 are placed on the ground, they are set at a 90° angle. The 90° angle between the two boundary telescopic rods 121 allows for the delineation of the sample plot without further angle adjustments. The device can be simply set up at one corner of the sample plot to be tested to complete the positioning and delineation, making the operation simple and convenient.

[0032] Furthermore, such as Figure 5 As shown, the bottom of the main pole 1 is provided with a retractable insert rod 15. The bottom of the main pole 1 also has multiple locking holes 16 distributed axially. The insert rod is provided with an elastic catch 151, which engages with the locking holes 16 to lock the insert rod 15. In use, the insert rod 15 is pulled out from the bottom of the main pole 1 and inserted into the ground for further stabilization. When not in use, it is retracted into the main pole 1, with the insert rod 15 embedded in the ground for greater overall stability. Operation is simple.

[0033] Furthermore, such as Figure 1 and Figure 2 As shown, the main rod 1 is equipped with a telescopic support rod assembly 17 for circumferential support on the ground. The telescopic support rod assembly 17 is a retractable telescopic structure; each support rod of the telescopic support rod assembly 17 can be individually extended or shortened. When extended, it can support the ground. The number of support rods in the telescopic support rod assembly 17 can be set as needed. When facing uneven ground, some support rods can be extended or shortened as needed to place the entire device in a vertical position. The telescopic insertion rod 15, in conjunction with the telescopic support rod assembly 17, makes the entire support more stable when supported on the ground. When the entire device is folded up, the telescopic support rod assembly 17 can be closed, making operation simple and easy to carry.

[0034] Furthermore, the main rod 1 is a telescopic structure. During use, the main rod can be extended according to the specific conditions of the sample to be tested. When the entire device is folded up, the main rod 1 can be retracted, making the overall device smaller, easier to carry, and simpler and more convenient to operate.

[0035] Furthermore, the imaging device 11 is an automated plant phenotypic analysis device capable of analyzing relevant data. It can identify various data of plants within the quadrat, including plant species, quantity, coverage, and phenological period, by taking photos of the quadrat.

[0036] The working principle of this embodiment is as follows:

[0037] The lower end of the main pole is equipped with a boundary positioning rod assembly for marking the sample plot boundaries on the ground. This assembly includes two outwardly extending boundary telescopic rods, which can be manually adjusted using the scales on the rods. Extending the rods to the corresponding length marks the sample plot area. When not in use, the telescopic rods can be folded up and secured in a clip for easier transport. The upper end of the main pole features a movable imaging device connected to a telescopic support rod. The imaging range of this device can be adjusted using a universal connector for photographing and analyzing the sample plots. The telescopic support rod assembly on the main pole, which provides circumferential support to the ground, along with the insertion rod at the bottom, further enhances the stability of the entire main pole. This allows for more convenient and efficient survey and analysis in sample plots inaccessible to humans.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
