[0039] Please refer to Figures 1-6This embodiment provides a portable ecological quadrat frame 100, which includes a connecting strip 300 and at least four ecological quadrat positioning posts 200.

[0040] The ecological quadrat positioning column 200 includes a positioning rod 210, a positioning seat 220, a level calibrator 230, a laser calibrator 240, a laser calibration point 250, and multiple positioning buckles 260.

[0041] The positioning base 220 is connected to the top of the positioning rod 210; the level calibrator 230 is connected to the top of the positioning base 220;

[0042] The laser calibrator 240 and the laser calibration point 250 are connected at an angle to the side of the positioning base 220 around the axis of the positioning base 220; the cursor positioning point is used to receive the laser positioning beam emitted by the laser calibrator 240 from the external adjacent ecological quadrat positioning column 200.

[0043] Multiple positioning buckles 260 are connected to the side of the positioning base 220 at intervals around the axis of the positioning base 220, and are used to connect with the connecting strap 300. This embodiment is illustrated by taking the arrangement of multiple positioning buckles 260 at 90° intervals around the axis of the positioning base 220 as an example.

[0044] The connecting strap 300 is wound inside the positioning base 220, and the side of the positioning base 220 is also provided with a passage 221 for the free end of the connecting strap 300 to extend out. The free end of the connecting strap 300 is connected to a connecting buckle 310, and the passage 221 and the positioning buckle 260 are set at an angle around the axis of the positioning base 220. The positioning buckle 260 is used to engage with the connecting buckle 310 of the adjacent ecological quadrat positioning column 200. In other embodiments of this utility model, the connecting strap 300 can also be placed outside the positioning base 220, and both ends of the connecting strap 300 are provided with connecting buckles 310. The connecting buckles 310 at both ends of the connecting strap 300 are respectively used to engage with the connecting buckles 310 of two adjacent ecological quadrat positioning columns 200.

[0045] Please refer to Figures 1-6The working principle of the ecological quadrat positioning post 200 is as follows: The ecological quadrat positioning post 200 is used together with multiple external ecological quadrat positioning posts 200 to form a portable ecological quadrat frame 100. When configuring the ecological quadrat positioning post 200, it adopts a structural setting including a positioning rod 210, a positioning seat 220, a horizontal calibrator 230, a laser calibrator 240, a laser calibration point 250, and a positioning buckle 260. The positioning seat 220 is connected to the top of the positioning rod 210, and the horizontal calibrator 230 is connected to the top of the positioning seat 220. Thus, the ecological quadrat positioning post 200 can be horizontally calibrated and positioned by the horizontal calibrator 230 to assist in horizontal adjustment and ensure that the true projection of the quadrat boundary is consistent with the horizontal plane in complex terrain.

[0046] By connecting the laser calibrator 240 and the laser calibration point 250 to the side of the positioning base 220, when forming the portable ecological quadrat frame 100, the laser positioning beam emitted by the laser calibrator 240 of the adjacent ecological quadrat positioning column 200 can be received by the cursor of one of the ecological quadrat positioning columns 200, thereby completing the corner point positioning.

[0047] Furthermore, by engaging the connecting buckle 310 of the connecting strap 300 located outside the positioning seat 220 with the positioning buckles 260 on two adjacent positioning seats 220, or by engaging the connecting buckle 310 on the connecting strap 300 inside the positioning seat 220 with the connecting buckle 310 of the adjacent ecological quadrat positioning post 200, it is possible to connect two adjacent ecological quadrat positioning posts 200 through the connecting strap 300 when forming the portable ecological quadrat frame 100, based on the aforementioned laser positioning, so that the two adjacent ecological quadrat positioning posts 200 do not need to be physically connected, thereby achieving precise distance control between the positioning rods 210; and by using the laser calibrator 240 for orientation projection, combined with the connecting strap 300 to provide boundary length calibration, the geometric accuracy control of the ecological quadrat can be achieved, thereby effectively improving the accuracy of corner point positioning and boundary through the combination of the two.

[0048] In summary, the ecological quadrat positioning column 200 is applied to the portable ecological quadrat frame 100. It has a simple structure, is flexible and convenient to use, has a wide range of applications, can meet different size requirements according to needs, and can accurately locate and calibrate each corner point of the quadrat.

[0049] Please refer to Figures 1-6The portable ecological quadrat frame 100 is composed of the aforementioned ecological quadrat positioning column 200, thus possessing all the advantages of the aforementioned ecological quadrat positioning column 200. Furthermore, the portable ecological quadrat frame 100 adopts a four-corner independent positioning structure, with each corner equipped with a laser calibrator 240 and a laser calibration point 250, as well as a horizontal calibrator 230. The height and direction can be adjusted according to the terrain, without the need for a unified central support point.

[0050] Furthermore, the adjustable boundary can be formed by the fastening of the positioning buckle 260 and the connecting buckle 310 on the connecting strap 300, no longer limited to a fixed square or relying on the projection of the built-in structure of the equipment, and supports rapid switching between multiple scales (1×1m, 2×2m, 5×5m, etc.); the laser calibrator 240 provides directional guidance, and the connecting strap 300 ensures the accuracy of the side length. The combination of the two effectively improves the corner point positioning and boundary accuracy; it can realize the accurate measurement of the quadrat boundary, the retractable layout, and the flexible adjustment of various sizes.

[0051] Moreover, the portable ecological quadrat frame 100 has a wide range of applications, suitable for non-flat terrains such as slopes and wetlands. It is horizontally adjustable, and each ecological quadrat positioning column 200 is equipped with a level calibrator 230, which can be a bubble level. It is portable and modular: each positioning unit can be disassembled and carried, supporting quick deployment by one or two people without complicated assembly.

[0052] It should be noted that the ecological quadrat positioning post 200 can meet the multi-scale requirements of the portable ecological quadrat frame 100. Users can set different side lengths according to research purposes, such as 1×1m, 2×2m, 5×5m, 10×10m, etc., all of which can be accurately positioned using a measuring tape and the vertical relationship of the four corners confirmed by a laser device. In addition, the ecological quadrat positioning post 200 is used in the portable ecological quadrat frame 100 to quickly and accurately determine the quadrat range and perform horizontal calibration in ecological quadrat surveys, thereby improving the accuracy and efficiency of ecological surveys. It is also suitable for standardized survey sampling of different vegetation types such as trees, shrubs, and herbs.

[0053] Further, please refer to Figures 1-6In this embodiment, the connecting tape 300 is wound up to the positioning seat 220. When configuring the laser calibrator 240 and the laser calibration point 250, they are set at an angle. In order to combine them into a portable ecological sample frame 100, the laser calibrator 240 and the laser calibration point 250 are set at a 90° angle around the axis of the positioning seat 220. The port 221 and the positioning buckle 260 are also set at a 90° angle around the axis of the positioning seat 220. In other embodiments of this utility model, in order to enable multiple ecological quadrat positioning posts 200 to be distributed linearly, and thus enable at least three ecological quadrat positioning posts 200 to form one side of the portable ecological quadrat frame 100 to improve its applicable size range, the laser calibrator 240 and the laser calibration point 250 can be set at a 180° angle around the axis of the positioning seat 220; the port 221 and the positioning buckle 260 are set at a 180° angle around the axis of the positioning seat 220.

[0054] In forming the portable ecological quadrat frame 100, taking four ecological quadrat positioning posts 200 as an example, the portable ecological quadrat frame 100 can be quickly formed by rectangularly distributing the ecological quadrat positioning posts 200, laser positioning adjacent ecological quadrat positioning posts 200, and connecting them with connecting buckles 310 and positioning buckles 260. The overall installation and use steps are simple and convenient, and the efficiency is high. It should be noted that when the number of ecological quadrat positioning posts 200 in the portable ecological quadrat frame 100 is more than four, the purpose is to ensure that the number of ecological quadrat positioning posts 200 on one side of the portable ecological quadrat frame 100 is greater than two. Therefore, in this case, taking... Taking three ecological quadrat positioning posts 200 on one side as an example, the laser calibrator 240 and laser calibration point 250 of the ecological quadrat positioning posts 200 at both ends can be set at a 90° angle around the axis of the positioning base 220, and the port 221 and positioning buckle 260 can be set at a 90° angle around the axis of the positioning base 220; while the laser calibrator 240 and laser calibration point 250 of the ecological quadrat positioning post 200 located in the middle position can be set at a 180° angle around the axis of the positioning base 220, and the port 221 and positioning buckle 260 can be set at a 180° angle around the axis of the positioning base 220. In this way, the size requirements of more portable ecological quadrat frames 100 can be met.

[0055] Further, please refer to Figures 1-6In this embodiment, to adapt to different ground environments, especially to meet the needs of use in environments with slopes or other elevation differences, the positioning rod 210 is a telescopic rod, allowing for height adjustment through its extension and retraction. Size markings are provided on the outer periphery of the telescopic rod to determine its actual length. For easy insertion into the ground, the end of the positioning rod 210 away from the positioning seat 220 is provided with a pointed tip. Therefore, the ecological quadrat positioning post 200 can easily adjust its height on different terrains and adapt to the influence of slopes or obstacles.

[0056] In this embodiment, to facilitate positioning and height adjustment during use, the laser calibrator 240 and the laser calibration point 250 are equidistant from the top of the positioning base 220 along the axial direction of the positioning base 220. Similarly, the orifice 221 and the positioning buckle 260 are equidistant from the top of the positioning base 220. This arrangement ensures that the laser calibrator 240 and the laser calibration point 250 are in the same radial plane relative to the axis of the positioning base 220, and that the orifice 221 and the positioning buckle 260 are in the same radial plane relative to the axis of the positioning base 220. This facilitates positioning and adjustment during later use, thereby improving its efficiency.

[0057] To improve the flexibility of the positioning seat 220, it can be connected to the positioning rod 210 via a universal connector, or rotatably connected to the positioning rod 210 around its axis, thereby allowing the laser projection direction to be adjusted as needed. To measure the extension length of the connecting buckle 310 of the connecting strap 300 when it is connected to the positioning buckle 260, graduation marks are provided on the connecting strap 300.

[0058] Based on the above structure, in order to improve the flexibility of use, the positioning base 220 may include a positioning shaft and a first rotating platform 222; the first rotating platform 222 is rotatably connected to the positioning shaft, and the positioning shaft is connected to the positioning rod 210; the laser calibrator 240 and the laser calibration point 250 are both connected to the first rotating platform 222.

[0059] In addition, the positioning seat 220 includes a second rotating platform 223; the second rotating platform 223 is rotatably connected to the positioning shaft; the positioning buckle 260 is connected to the second rotating platform 223; and when the connecting belt 300 is wound into the positioning seat 220, both the connecting belt 300 and the positioning buckle 260 can be connected to the second rotating platform 223, and are opened in the second rotating platform 223 through the opening 221.

[0060] Furthermore, the positioning shaft also includes a horizontal positioning platform 224 connected to the top of the positioning shaft, and a horizontal calibrator 230 connected to the horizontal positioning platform 224; the outer periphery of the horizontal positioning platform 224 is provided with an angle mark around the axis of the positioning shaft, and the outer periphery of the first rotating platform 222 and the second rotating platform 223 are respectively provided with a first positioning mark 225 and a second positioning mark 226.

[0061] By setting up the first rotating platform 222, the second rotating platform 223, and the horizontal positioning platform 224, the positions of the laser calibrator 240 and the laser calibration point 250 connected to the first rotating platform 222 relative to the positioning rod 210 can be adjusted independently. During the adjustment process, the angle mark on the horizontal positioning platform 224 can be used to position the first positioning block 225, thereby determining the change in angular position before and after rotation. Similarly, the positions of the connecting belt 300 and the positioning buckle 260 connected to the second rotating platform 223 relative to the positioning rod 210 can also be adjusted independently. During the adjustment process, the angle mark on the horizontal positioning platform 224 can be used to position the second positioning block 226, thereby determining the change in angular position before and after rotation.

[0062] In summary, please refer to Figures 1-6 It should also be noted that the level calibrator 230 of the portable ecological sample frame 100 can be a built-in high-precision bubble level, used to detect whether the positioning rod 210 is perpendicular to the ground; after the positioning rod 210 is inserted into the ground, by observing the position of the bubble in the level calibrator 230, the angle of the positioning rod 210 can be manually adjusted to keep it perpendicular.

[0063] Furthermore, the positioning rod 210 can be made of high-strength, lightweight alloy material, with an anti-corrosion coating on the outer shell. The positioning rod 210 is a multi-section telescopic structure with a rotary locking device, allowing users to freely adjust the rod length according to the terrain. The rod has markings on it.

[0064] The laser calibrator 240 features ±2 mm precision laser projection, capable of generating red or green laser beams for easy field observation; the laser calibration point 250 serves as a calibration point for receiving the laser beam, allowing users to observe laser position deviations and aid in accuracy calibration; the level calibrator 230 is used for terrain tilt calibration.

[0065] Although this device uses a non-physical connection method, a closed quadrilateral frame is formed by the connection between the connecting buckle 310 on the connecting strap 300 and the positioning buckle 260.

[0066] In addition, the connecting strap 300 will be replaced with a measuring tape. Both ends of the measuring tape are equipped with connecting buckles 310. Users can insert the connecting buckles 310 at both ends into the positioning buckles 260 of the two ecological quadrat positioning columns 200, read the scale value and adjust the length. Laser positioning assists in determining whether a standard rectangle has been formed.

[0067] The four sides are laid out clockwise and connected sequentially to form a complete quadrat boundary; if the calibration error at any point exceeds the set value (e.g., ±5mm), the height of the corresponding connecting strip 300 or positioning rod 210 can be adjusted.

[0068] Furthermore, the portable ecological quadrat frame 100 supports rapid adjustment at multiple scales. By changing the length of the connecting strap 300 and the positioning rod 210, or adjusting the connection position, it is possible to convert quadrats with side lengths of 1m, 2m, 5m, and 10m. Each connecting strap 300 is marked with commonly used standard length color markings (such as red for 1m and blue for 2m) for easy identification and deployment.

[0069] Please refer to Figures 1-6 The steps for using the portable ecological sample box 100 are as follows:

[0070] Select the center point of the quadrat, set the first ecological quadrat positioning column 200, and adjust its position according to the horizontal calibrator 230 to make it vertical;

[0071] Place the remaining three ecological quadrat positioning columns 200mm in a clockwise direction;

[0072] Use a laser calibrator 240 for initial positioning to ensure the stability of the laser intersection point between two adjacent rods;

[0073] Connect the connecting strips 300 sequentially and adjust them to the required length.

[0074] Repeatedly calibrate the laser position and the length of the connecting strip 300 to confirm the diagonal laser symmetry and the parallelism of the four sides;

[0075] Complete the quadrat layout and record the GPS coordinates of the four points.

[0076] For forest ecosystems, quadrats can be set up in woodlands with steep slopes; when applied to grassland monitoring, quadrats can be set up quickly in areas without ground cover; in wetland ecosystems, the telescopic function of the poles can be used to deal with unstable ground conditions; and when applied to urban green space surveys, non-invasive quadrats can be set up without damaging the ground structure.

[0077] In summary, please refer to Figures 1-6This portable ecological quadrat frame 100 achieves high-precision positioning and calibration for ecological quadrat deployment, making it particularly suitable for uneven terrain or complex landform environments. Furthermore, the four ecological quadrat positioning posts 200 are independent of each other, facilitating transportation and rapid field deployment, and do not rely on fixed connection structures, thus enhancing adaptability. Laser calibration significantly improves deployment efficiency and accuracy, avoiding errors associated with traditional manual measurements. The snap-fit ​​connection method of the connecting strap 300 is both simple and reliable, enabling flexible switching across multiple scales. The overall structure is lightweight and easy to operate, making it widely applicable in ecological monitoring, forestry surveys, grassland management, and scientific research and teaching.

[0078] Moreover, its structural design is reasonable and suitable for ecological research in various natural environments. It can significantly improve the efficiency and accuracy of quadrat layout and has good application prospects and promotion value.

[0079] Rotational damping is provided at the rotatable connection between the positioning base 220 and the positioning rod 210, thus adopting a damping adjustment design. The rotational resistance can be manually controlled, and the rotatable connection allows the positioning base 220 to allow the laser calibrator 240 and the laser calibration point 250 to rotate 360° horizontally, facilitating the adjustment of the laser projection direction. When used on slopes, the laser angle can be finely adjusted by rotation to ensure the precise intersection of the four edges. Moreover, the laser calibrator 240 projects a visible laser beam onto the laser calibration point 250 on the adjacent ecological quadrat positioning post 200, which can be used to calibrate the quadrat boundary. The emission angle of the laser beam can be adjusted by rotation to ensure that a standard geometric shape can still be formed in complex terrain. The connecting strip 300 is equipped with scale marks for measuring the distance between two adjacent ecological quadrat positioning posts 200 after connection, ensuring the geometric accuracy of the quadrat.

[0080] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
