Description

Technical Field

[0001] This utility model belongs to the field of forest community survey tool design technology, specifically relating to a benchmark for community quadrat and quadrat surveys. Background Technology

[0002] The traditional method of setting up quadrats / circles in forest / grassland communities often relies on manual measuring tape. This method requires someone else or other tools to fix one end of the measuring tape, and then the surveyor pulls the free end of the measuring tape to the survey boundary. Alternatively, a rope of the target size can be measured first, and one end of the rope can be tied to a traditional marker (i.e., just a pole that can be fixed at the target position) before the free end of the fixed-length rope is pulled to the survey boundary. This method results in low efficiency in quadrat / circle positioning, which in turn reduces the efficiency of field operations. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to provide a marker for surveying community quadrats and quadrats, which can overcome the technical problem of low positioning efficiency and reduced field operation efficiency when using traditional manual rulers or traditional markers with fixed-length ropes to delineate forest community boundaries.

[0004] To address the aforementioned problems, this utility model provides a marker for community quadrat and quadrat surveys, comprising a marker body having a hollow cylindrical section with a accommodating space, and a measuring tape device assembled within the accommodating space. The measuring tape device includes a tape that can be wound and has graduations. A through hole is formed on the wall of the hollow cylindrical section, and the tape passes through the through hole with its free end located outside the wall of the hollow cylindrical section.

[0005] In some embodiments, an anti-detachment block is provided on the free end of the tape, the through hole is a rectangular hole, the anti-detachment block is a rectangular block, and the length of the anti-detachment block is greater than the length of the through hole or the width of the anti-detachment block is greater than the width of the through hole.

[0006] In some embodiments, a fixed shaft is provided within the receiving space, the axial direction of the fixed shaft coincides with the axis of the hollow cylindrical section, and both ends of the fixed shaft are fixed to both ends of the hollow cylindrical section. The measuring tape device also includes a drum and a torsion spring. The fixed end of the measuring tape is fixed to the drum, one end of the torsion spring is fixedly connected to the drum, and the other end of the torsion spring is fixedly connected to the fixed shaft, so that the measuring tape can be automatically wound around the outer circumferential wall of the drum when the free end of the measuring tape is released from tension.

[0007] In some embodiments, annular flanges are formed at both axial ends of the roll, and a guide groove is formed between the two annular flanges to guide the roll of the tape.

[0008] In some embodiments, a plurality of measuring tape devices are provided in the accommodating space, and each measuring tape device is sequentially assembled on the fixed shaft along the axial direction of the hollow cylindrical section, and the free ends of each measuring tape device are evenly spaced along the circumferential direction of the hollow cylindrical section.

[0009] In some embodiments, four measuring tape devices are provided.

[0010] In some embodiments, the marker body includes a detachably connected upper section and a lower section, with the hollow cylindrical section situated on the lower section.

[0011] In some embodiments, the upper section and the lower section are threaded together.

[0012] In some embodiments, the end of the lower segment away from the upper segment is formed into a sharp angle.

[0013] In some embodiments, a plurality of color mark segments are formed on the outer circumferential wall of the marker body, which are spaced apart along its length. The length of each color mark segment is equal, and the length of the interval between two adjacent color mark segments is equal to the length of each color mark segment.

[0014] This utility model provides a marker for surveying quadrats and transects in forest communities. It integrates a measuring tape device into the hollow section of the marker body, allowing the marker body to be fixed to the ground while also providing a tape that can be pulled out to a target length. This makes it more convenient to conduct surveys on delineating quadrats or transects in forest communities. It effectively overcomes the shortcomings of traditional methods, such as using manual measuring tapes or fixed-length ropes attached to traditional markers to delineate forest community boundaries, which are inefficient and reduce fieldwork efficiency. This invention improves fieldwork efficiency. Attached Figure Description

[0020] See also Figures 1 to 3 As shown in the figure, according to an embodiment of the present invention, a marker for community quadrat survey is provided, including a marker body 1, the marker body 1 having a hollow cylindrical section 11 with a receiving space (not indicated in the figure), and a measuring tape device 2, the measuring tape device 2 being assembled in the receiving space, the measuring tape device 2 including a tape 21 (e.g., a traditional tape measure) that can be wound and has graduations, the hollow cylindrical section 11 having a through hole (not indicated in the figure), the tape 21 passing through the through hole and the free end of the tape 21 (i.e., the end of the tape 21 that can be pulled by the operator) being located outside the cylindrical wall of the hollow cylindrical section 11.

[0021] In this technical solution, the measuring tape device 2 is integrated into the hollow cylindrical section 11 of the marker body 1, so that the marker body 1 can be fixed to the ground and also has a tape 21 that can be pulled out to a target length. This makes it more convenient to conduct surveys on forest community quadrats or transects. It effectively overcomes the shortcomings of low positioning efficiency and reduced field operation efficiency when using traditional manual tape measure or traditional markers with fixed-length ropes to delineate forest community boundaries, thus improving the efficiency of field operations.

[0022] See details Figure 3 As shown in some embodiments, the free end of the measuring tape 21 is provided with an anti-detachment block 22, the through hole is a rectangular hole, the anti-detachment block 22 is a rectangular block, and the length of the anti-detachment block 22 is greater than the length of the through hole or the width of the anti-detachment block 22 is greater than the width of the through hole.

[0023] In this technical solution, by setting an anti-detachment block 22 on the free end of the measuring tape 21, it can prevent the measuring tape 21 from being completely wound into the aforementioned receiving space, thus hindering its reuse. Furthermore, the anti-detachment block 22 can improve the stability of the operator's grip on the free end of the measuring tape 21. In a specific embodiment, the anti-detachment block 22 is made of plastic, and it can be integrated with the free end of the measuring tape 21 through a snap-fit ​​connection. Using plastic for the anti-detachment block 22 can reduce the overall weight of the marker pole, improving its ease of use and carrying. In a more preferred embodiment, the anti-detachment block 22 has a piercing positioning element (not shown in the figure) that can be inserted into the ground. The tip of this piercing positioning element can be inserted into the ground to position the free end of the measuring tape 21. This eliminates the need for a separate external structure for positioning the free end of the measuring tape 21, further improving the compactness of the marker pole's structure.

[0024] In some embodiments, a fixed shaft 3 is provided within the accommodating space. The axial direction of the fixed shaft 3 coincides with the axis of the hollow cylindrical section 11, and both ends of the fixed shaft 3 are fixed to both ends of the hollow cylindrical section 11 (e.g., supported on the inner wall of the hollow cylindrical section 11 by corresponding end caps). The measuring tape device 2 also includes a drum 23 and a torsion spring (not shown in the figure). The fixed end of the measuring tape 21 is fixed to the drum 23. One end of the torsion spring is fixedly connected to the drum 23, and the other end of the torsion spring is fixedly connected to the fixed shaft 3, so that it can be automatically wound around the outer circumferential wall of the drum 23 when the free end of the measuring tape 21 is released from tension. It is understood that the aforementioned torsion spring is a conventional helical spring, and in the specific application of this utility model, a commercially available part of a suitable model can be selected.

[0025] In this technical solution, by setting a torsion spring between the drum 23 and the fixed shaft 3, the torsional restoring force of the torsion spring can be used to achieve automatic retraction and storage of the tape 21, which can further facilitate field operations and improve work efficiency.

[0026] In some embodiments, annular flanges 231 are formed at both axial ends of the roll 23, and a guide groove is formed between the two annular flanges 231 to guide the winding of the tape 21.

[0027] In this technical solution, by forming an annular flange 231 at each of the two axial ends of the drum 23, the winding area of ​​the tape 21 is confined within the guide groove between the two, which can prevent entanglement during the automatic retraction and storage of the tape 21.

[0028] In some embodiments, a plurality of measuring tape devices 2 are provided in the accommodating space. Each measuring tape device 2 is sequentially assembled on the fixed shaft 3 along the axial direction of the hollow cylindrical section 11, and the free ends of each measuring tape device 2 are evenly spaced along the circumferential direction of the hollow cylindrical section 11. Specifically, in a specific embodiment, a total of four measuring tape devices 2 are provided.

[0029] In this technical solution, multiple measuring tape devices 2 are simultaneously set up, and the free ends of the tapes 21 of each measuring tape device 2 are evenly arranged along the circumference of the marker pole. This allows for fixed-distance boundary demarcation corresponding to different directions, without the need to adjust the direction (rotate) of the marker pole body 1 during the boundary demarcation process, further improving work efficiency. When there are four measuring tape devices 2, the free ends of the tapes 21 of each measuring tape device 2 are pulled out to correspond to the four corners of the quadrat, making boundary demarcation even faster.

[0030] In some embodiments, the marker body 1 includes a detachably connected upper section 101 and a lower section 102. Preferably, the upper section 101 and the lower section 102 are threaded together, and the hollow cylindrical section 11 is located on the lower section 102. Positioning the hollow cylindrical section 11 on the lower section 102, that is, placing each measuring tape device 2 below the marker body 1, prevents pulling on the measuring tapes 21 in the boundary calibration state from obstructing the operation. Furthermore, designing the marker body 1 as a detachable structure reduces storage space and facilitates its storage when not in use. See details. Figure 2 As shown, in a specific embodiment, a stud 1011 is formed on the bottom end of the upper section 101, and a threaded hole 1021 is formed on the top end of the lower section 102 to be threadedly connected to the stud 1011. Specifically, the threaded hole 1021 can be constructed at the center of the end cap at the top end of the fixed shaft 3.

[0031] In order to facilitate the fixing of the marker body 1, the lower section 102 is formed into a sharp corner 13 at the end away from the upper section 101, so as to pierce the ground surface through the sharp corner 13, thereby ensuring that the marker body 1 can be reliably fixed at the target position.

[0032] See details Figure 1As shown, in some embodiments, a plurality of color mark segments 12 (e.g., red plastic film affixed to the outer circumferential wall of the marker body 1, in which case the marker body 1 itself can be white) are formed on the outer circumferential wall of the marker body 1. Each color mark segment 12 has an equal length, and the interval between two adjacent color mark segments 12 is equal to the length of each color mark segment 12. In this way, by comparing each color mark segment 12 on the marker body 1 with the trees in the environment, the height of the surrounding trees can be quickly determined.

[0033] It will be readily understood by those skilled in the art that the aforementioned advantageous methods can be freely combined and superimposed without conflict.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. The above are only preferred embodiments of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
