Description

Technical Field

[0001] This utility model relates to the technical field of forest resource survey equipment, and in particular to a measuring device for the growth process of standing trees. Background Technology

[0002] Forest resource monitoring is a crucial topic in global change research and sustainable development.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] This utility model provides a technical solution: a device for measuring the growth process of standing trees, see [link to relevant documentation]. Figures 1 to 4 It includes a height measuring rod 1 and a horizontal rod. The horizontal rod is installed at the top of the height measuring rod 1 through a connector 2. The horizontal rod body 42 has a connecting end, a movable end 3 and a fixed end 4. The connecting end is fixedly connected to the connector 2. The fixed end 4 is set away from the connector 2. The movable end 3 is slidably set between the connecting end and the fixed end 4. The fixed end 4 is provided with a fixed claw 41. The movable end 3 includes a movable claw sleeve 32. The movable claw sleeve 32 is provided with a movable claw 31. The horizontal rod body 42 is provided with a measuring ruler 33. The head end of the measuring ruler 33 is connected to the movable claw sleeve 32.

[0033] Specifically, this measuring device mounts a horizontal rod to the top of the measuring rod 1 via a connector. The horizontal rod has a connecting end, a movable end 3, and a fixed end 4. The movable end 3 is slidable, and the fixed end 4 has a fixed claw 41. The movable claw sleeve 32 on the movable end 3 has a movable claw 31, and the head end of the measuring ruler 33 is connected to the movable claw sleeve 32. In this way, the position of the movable end 3 can be flexibly adjusted according to the different thicknesses of the standing trees. The fixed claw 41 and the movable claw 31 cooperate to firmly clamp the standing trees, and the measuring ruler 33 moves with the movable end 3 to accurately measure the relevant growth data of the standing trees.

[0034] As an optional implementation, in some embodiments, the height measuring rod 1 is formed by several sleeve rods 11 connected together, with the upper sleeve rod movably fitted inside the lower sleeve rod in two adjacent sleeve rods 11. This allows the length of the height measuring rod 1 to be flexibly adjusted according to the actual height of the standing tree. The overall height can be easily changed by the telescopic sleeve rods 11, eliminating the need to prepare multiple fixed-length height measuring rods of different specifications. This not only saves storage space and cost but also greatly enhances the applicability and portability of the device, facilitating the measurement of the growth process of standing trees in different scenarios.

[0035] As an optional implementation, in some embodiments, the connector 2 includes a fixing plate 21, a first slot 12 is formed at the top of the height measuring rod 1, the fixing plate 21 is snapped into the first slot 12, and a second slot 24 is formed on the fixing plate 21, the connecting end is snapped into the second slot 24. This snap-fit ​​method has a simple structure, is easy to operate and disassemble, and facilitates the assembly and storage of the measuring device.

[0036] In the above embodiment, a pulley assembly is further provided at the end of the fixed plate 21 away from the fixed end 4. The pulley assembly includes two connecting rods 22 and a pulley 23. One end of each connecting rod 22 is connected to the fixed plate 21, and the other end of each connecting rod 22 is connected to a rotating rod. The rotating rod is provided with a pulley 23, and the end of the measuring scale 33 is slidably connected to the pulley 23. This structure allows the measuring scale 33 to slide smoothly with the help of the pulley 23 when the movable end 3 moves, reducing the frictional resistance of the measuring scale 33 and making the measurement operation easier and less strenuous.

[0037] As an optional implementation, in some embodiments, a groove 44 is provided on the horizontal bar, and a movable claw sleeve 32 is slidably disposed within the groove 44. A spring 43 is provided within the groove 44, with one end of the spring 43 fixedly connected to the inner wall of the groove 44 and the other end of the spring 43 fixedly connected to the movable claw sleeve 32. The spring 43 enables the movable claw sleeve 32 to have an automatic reset function, allowing it to quickly return to its initial state after adjusting its position to measure standing timbers of different thicknesses.

[0038] As an optional implementation, in some embodiments, both the fixed claw 41 and the movable claw 31 are located on the same side of the horizontal bar. This allows for better clamping of the standing tree during its growth process, improving stability.

[0039] As an optional implementation, in some embodiments, the measuring ruler 33 is made of fiberglass or PVC plastic; the fixed claw 41, the movable claw 31 and the movable claw sleeve 32 are all made of aluminum alloy; the sleeve rod 11 is made of aluminum alloy; the fixed plate 21, the two connecting rods 22 and the rotating rod are all made of aluminum alloy.

[0040] Specifically, the measuring ruler 33 is made of fiberglass or PVC plastic, which is lightweight and flexible, making it easy to slide and operate smoothly during measurement. It is also low in cost and corrosion resistant. The fixed claw 41, movable claw 31, movable claw sleeve 32, sleeve rod 11, fixed plate 21, connecting rod 22 and rotating rod are all made of aluminum alloy. Aluminum alloy has high strength and light weight, which can ensure that the device structure is stable, durable and not easily deformed. It can adapt to the standing tree measurement work in different environments, and the uniform material of each component makes it easy to process, manufacture and maintain.

[0041] The method of using this measuring device is as follows: When using it, according to the experimental requirements, place the measuring rod 1 at the base of the target tree trunk. Pull the sleeve 11 upwards section by section to the desired height. When the desired height is reached, read the tree height data H1. Another person reads the value L1 at the end of the measuring ruler 33 on the sleeve 11. Then, pull the measuring ruler 33, which pulls the spring 43 through the movable claw sleeve 32, causing the movable claw 31 to separate from the fixed claw 41. Place the fixed claw 41 against the east side of the tree trunk. Release the measuring ruler 33, allowing the movable claw 31 to adhere to the west side of the tree trunk due to the spring force of 43. At this point, read the value L2 at the end of the measuring ruler 33 on the sleeve 11. The difference between the two readings is the east-west diameter D1 of the tree at a certain height. Then, repeat the above steps to measure the north-south diameter D1. The average of the two measurements is the diameter D1 of the tree at that certain height. After the diameter measurement is completed, pull the measuring ruler 33 to disengage the movable claw 31 from the tree trunk. Release the measuring ruler 33, and the movable claw 31 will close with the fixed claw 41. Continue to pull the sleeve 11 upwards to measure the diameter D2 at the next height H2. Based on the measurements of multiple heights and diameters, an allometric growth equation for the tree is established. After the measurement is completed, release the measuring ruler 33 and push the sleeve 11 downwards for storage, so that it can be used again next time.
