Description

Technical Field

[0001] This utility model relates to the field of survey quadrat technology, and in particular to a modular forest and grassland survey quadrat. Background Technology

[0002] A quadrat is a square plot of a certain area and shape delineated within a forest or grassland area. It is used to conduct quantitative surveys and analyses of plant communities, vegetation cover, biomass, etc., and is an important means of obtaining basic ecosystem data.

[0003] Traditional survey transects are typically constructed by welding steel pipes into a square frame at the location where sampling is required. Because of the welding, they are inconvenient to transport and carry. Furthermore, the dimensions are relatively fixed after welding, making it difficult to adjust them according to different survey objectives, vegetation types, or terrain conditions.

[0004] Therefore, in view of the fact that the traditional survey quadrats are inconvenient to transport and carry, and that their size is relatively fixed and difficult to adjust, a modular forest and grassland survey quadrats can be designed. By designing the survey quadrats as modular, detachable and adjustable structures, the above problems can be easily solved. Utility Model Content

[0005] To overcome the shortcomings of traditional survey transects, such as inconvenience in transportation and carrying, and relatively fixed size that is difficult to adjust, this utility model provides a modular forest and grassland survey transect.

[0006] The technical solution is as follows: A modular forest and grassland survey transect frame includes main frame poles, extension arms, fixed ground spikes, telescopic poles, and an image acquisition mechanism. There are four sets of main frame poles, with sampling pools between them to determine the sampling range. The four sets of main frame poles are evenly distributed around the centers of the four sides of the sampling pools. Extension arms for adjusting the size of the sampling pools are fitted at both ends of each of the four sets of main frame poles. One set of extension arms has a first connector at the top of the end furthest from the main frame pole, and another set of extension arms has a second connector at the bottom of the end furthest from the main frame pole, corresponding to the first connector. The lower end of the second connector has fixed ground spikes for fixing the position of the survey transect frame. A telescopic pole is located above the first connector, and an image acquisition mechanism for collecting sample images is located above the telescopic pole.

[0007] Furthermore, a main scale is attached to the upper surface of the main frame rod, and multiple sets of main scale grooves are evenly opened on the surface of the main scale rod. Slide rails are provided on both the front and rear side walls of the main frame rod.

[0008] Furthermore, anti-detachment blocks are provided at the top and bottom of both ends of the two sets of slide rails, and a hidden main light groove is provided on the side of the front wall slide rail of the main frame rod near the sampling pool.

[0009] Furthermore, a storage cavity is provided at one end of the extension arm near the main frame rod, and both ends of the main frame rod extend into the storage cavity. Damping grooves corresponding to the slide rails are provided on both the front and rear side walls of the storage cavity, and anti-detachment grooves corresponding to the anti-detachment blocks are provided at the top and bottom of the damping grooves.

[0010] Furthermore, the top of the storage cavity has a through-hole for accommodating the main scale, and multiple sets of auxiliary scale grooves that match the main scale groove are evenly distributed along the surface edge of the extension arm. The side of the extension arm near the sampling pool has a hidden auxiliary light groove that matches the hidden main light groove. The cooperation between the auxiliary and main scale grooves further refines the accuracy of dimensional readings. When adjusting the sample frame size, staff can more accurately determine the required sampling range. The combination of the hidden auxiliary and hidden main light grooves allows staff to purchase external magnetic light strips and attach them to the hidden main and hidden auxiliary light grooves to illuminate the sampling area.

[0011] Furthermore, the upper end of the fixed spike is provided with a tray, and the upper center of the tray is provided with a sleeve. The center of the first connector and the second connector are both provided with a connecting hole to accommodate the sleeve. By the sleeve cooperating with the connecting hole in the center of the first connector and the second connector, a stable connection between the spike and the extension arm is achieved.

[0012] Furthermore, the lower end of the telescopic rod is provided with a pressure plate corresponding to the tray, and the lower center of the pressure plate is provided with a docking shaft, which is matched and inserted into the sleeve.

[0013] Furthermore, the image capture mechanism includes a pan-tilt unit, which is located at the top of the telescopic pole, and a camera is mounted on the top of the pan-tilt unit.

[0014] The beneficial effects are that, compared to traditional survey sample frames, which are inconvenient to transport and carry, and whose dimensions are relatively fixed and difficult to adjust, this application, through a modular design of four main frame rods and their two end extension arms, allows for flexible adjustment of the sampling pool size to adapt to different sampling needs. During transportation, the extension arms can slide inward along the slide rails, allowing the main frame rods to be completely stored in the storage cavity, significantly reducing the volume of the sample frame, facilitating carrying and transportation, improving work efficiency, and reducing transportation costs. The main scale and main scale groove on the main frame rods cooperate with the auxiliary scale groove on the extension arms, allowing staff to intuitively and accurately read and record the adjusted size data of the sample frame, further refining the accuracy of size reading. This allows for more precise determination of the required sampling range. By using the insertion sleeve of the fixed ground spike to engage with the connection holes of the first and second connectors at the end of the extension arm, and with the tray supporting the first and second connectors, the sample frame can be firmly fixed to the ground to prevent movement, ensuring the accuracy and stability of sampling. Through the combination of the telescopic rod, pan-tilt unit, and camera, the ecological conditions within the sample plot can be clearly captured, providing intuitive and accurate image data for subsequent data analysis and research. By combining the hidden main light slot of the main frame rod and the hidden auxiliary light slot of the extension arm, externally purchased magnetic light strips can be attached to illuminate the sampling area during nighttime sampling, ensuring the accuracy of the survey in low-light environments.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0022] Example 1

[0023] like Figures 1-5 As shown, the modular forest-grassland survey sample frame includes a main frame rod 1, an extension arm 2, a fixed ground spike 4, a telescopic rod 5, and an image acquisition mechanism 6. The main frame rod 1 is provided in four sets, and a sampling pool 3 is opened between the four sets of main frame rod 1 to determine the sampling range. The four sets of main frame rod 1 are evenly distributed at the center of the four sides of the sampling pool 3. The two ends of the four sets of main frame rod 1 are fitted with extension arms 2 to adjust the size of the sampling pool 3. One set of extension arms 2 has a first connector 18 at the top of the end away from the main frame rod 1, and the other set of extension arms 2 has a second connector 19 at the bottom of the end away from the main frame rod 1, corresponding to the first connector 18. The lower end of the second connector 19 has a fixed ground spike 4 for fixing the position of the survey sample frame. The telescopic rod 5 is provided above the first connector 18, and the image acquisition mechanism 6 for collecting sample images is provided above the telescopic rod 5.

[0024] The upper surface of the main frame rod 1 is fitted with a main scale 7, and multiple sets of main scale grooves 8 are evenly opened on the surface of the main scale 7. The front and rear side walls of the main frame rod 1 are equipped with slide rails 9. Through the setting of the main scale 7 and the main scale grooves 8, it is convenient for staff to read and record the size data of the sample frame after adjustment intuitively and accurately.

[0025] Both ends of the two sets of slide rails 9 are equipped with anti-detachment blocks 11 at the top and bottom. The front side wall slide rail 9 of the main frame rod 1 is provided with a hidden main light groove 10 on the side near the sampling pool 3. The anti-detachment blocks 11 can effectively limit the sliding range of the extension arm 2 on the slide rail 9, and prevent the extension arm 2 from sliding out of the main frame rod 1 too much, which would cause the sample frame size to become out of control.

[0026] The extension arm 2 has a storage cavity 12 at one end near the main frame rod 1. Both ends of the main frame rod 1 extend into the storage cavity 12. The front and rear side walls of the storage cavity 12 are provided with damping grooves 13 corresponding to the slide rail 9. The top and bottom of the damping grooves 13 are provided with anti-detachment grooves 14 corresponding to the anti-detachment blocks 11. Through the storage cavity 12 at one end of the extension arm 2, both ends of the main frame rod 1 can be stored in it, realizing a tight connection and adjustable function between the two. Through the damping grooves 13 corresponding to the slide rails 9 on the main frame rod 1, the extension arm 2 can slide freely on the slide rails 9 through the damping grooves 13, thereby flexibly adjusting the size of the sampling pool 3.

[0027] The top of the storage cavity 12 has a through-hole groove 15 for accommodating the main scale 7. Multiple sets of auxiliary scale grooves 16 that match the main scale groove 8 are evenly opened on the surface edge of the extension arm 2. The side of the extension arm 2 near the sampling pool 3 has a hidden auxiliary light groove 17 that matches the hidden main light groove 10. By cooperating with the main scale groove 8, the accuracy of size reading is further refined. When adjusting the size of the sample frame, the staff can more accurately determine the required sampling range. By combining the hidden auxiliary light groove 17 with the hidden main light groove 10, the staff can purchase external magnetic light strips and attach them to the hidden main light groove 10 and the hidden auxiliary light groove 17 to illuminate the sampling area.

[0028] The upper end of the fixed spike 4 is provided with a tray 20, and the upper center of the tray 20 is provided with a sleeve 21. The center of the first connector 18 and the second connector 19 are both provided with a connecting hole to accommodate the sleeve 21. By the sleeve 21 cooperating with the connecting hole in the center of the first connector 18 and the second connector 19, a stable connection between the spike and the extension arm 2 is achieved.

[0029] The lower end of the telescopic rod 5 is provided with a pressure plate 23 corresponding to the tray 20. The lower center of the pressure plate 23 is provided with a docking shaft 22. The docking shaft 22 is matched and inserted with the sleeve 21. The docking shaft 22 and the sleeve 21 are matched and inserted to provide a fixed connection between the telescopic rod 5 and the ground spike.

[0030] The image acquisition mechanism 6 includes a pan-tilt unit 24, which is located at the upper end of the telescopic pole 5. A camera 25 is installed at the upper end of the pan-tilt unit 24. Through the telescopic pole 5, the pan-tilt unit 24 and the camera 25, the ecological conditions in the sample plot can be clearly captured, providing intuitive and accurate image data for subsequent data analysis and research.

[0031] During transportation, the extension arm 2 is slid inward along the slide rail 9 so that the main frame rod 1 is completely stored in the storage cavity 12, greatly reducing the volume and making it easy to carry. After arriving at the survey site, the staff pulls the extension arms 2 at both ends of the four sets of main frame rods 1 to the required size, and determines the sample plot size through the main scale groove 8 and the auxiliary scale groove 16. Then, the ends of the extension arms 2 at both ends of the four sets of main frame rods 1 are aligned so that the primary connector is connected to the secondary connector.

[0032] Next, insert the sleeve 21 of the fixed ground spike 4 into the connection hole between the primary connector and the secondary connector, and support the primary connector and the secondary connector with the tray 20, and then press the fixed ground spike 4 into the soil to fix it.

[0033] Subsequently, the connecting shaft 22 at the lower end of the telescopic rod 5 is inserted into the insert sleeve 21 of the ground spike, so that the pressure plate 23 and the tray 20 cooperate to fix the primary connector and the secondary connector. Then, the telescopic rod 5 is stretched to a suitable height, and the pan-tilt unit 24 and the camera 25 are used to collect images of the samples in the sampling pool 3.

[0034] When sampling at night, staff can purchase magnetic light strips to attach to the hidden main light trough 10 and the hidden auxiliary light trough 17 to illuminate the sample plot area and ensure the accuracy of the survey in low light conditions.

[0035] Its working principle is as follows: four sets of main frame rods 1 form the basic framework of the sample plot. The extension arm 2 is sleeved on both ends of the main frame rod 1 to adjust the size of the sample plot. The end of the extension arm 2 near the main frame rod 1 is provided with a storage cavity 12, which can slide to store the main frame rod 1 for easy transportation. The surface of the extension arm 2 is provided with an auxiliary scale groove 16, which cooperates with the main scale groove 8 to improve the measurement accuracy. The ground spike 4 is fixed and connected to the first connector 18 and the second connector 19 at the end of the extension arm 2 through the insertion sleeve 21, and inserted into the ground to fix the sample plot. The distribution of vegetation in the sample plot is photographed through the image acquisition mechanism 6. The slide rail 9 of the main frame rod 1 is provided with a hidden main light groove 10, and the extension arm 2 is provided with a hidden auxiliary light groove 17 at the corresponding position, which can be externally attached with magnetic light strips to provide uniform lighting.

[0036] Its beneficial effects are significant. Through the cooperation of four main frame rods 1 and extension arms 2, the size of the sampling pool 3 can be flexibly adjusted to adapt to different sampling needs. The main scale 7 and main scale groove 8 on the main frame rod 1 cooperate with the auxiliary scale groove 16 on the extension arm 2, allowing staff to intuitively and accurately read and record the adjusted size data of the sample frame, further refining the accuracy of size reading and enabling more precise determination of the required sampling range. By cooperating with the connecting holes of the insertion sleeve 21 of the fixing spike 4 and the first connecting head 18 and the second connecting head 19 at the end of the extension arm 2, and with the tray 20 supporting the first connecting head 18 and the second connecting head 19, the sample frame can be firmly fixed to the ground, preventing... The system prevents movement, ensuring the accuracy and stability of sampling. The combination of telescopic rod 5, pan-tilt unit 24, and camera 25 allows for clear imaging of the ecological conditions within the sample plot, providing intuitive and accurate image data for subsequent data analysis and research. The combination of the hidden main light slot 10 of the main frame rod 1 and the hidden auxiliary light slot 17 of the extension arm 2 allows for the attachment of externally purchased magnetic light strips to illuminate the sampling area during nighttime sampling, ensuring the accuracy of the survey in low-light environments. During transportation, the extension arm 2 can slide inward along the slide rail 9, allowing the main frame rod 1 to be completely stored in the storage cavity 12, significantly reducing the volume of the sample plot, facilitating carrying and transportation, improving work efficiency, and reducing transportation costs.
