Description

Technical Field

[0001] This utility model relates to the field of forest tree measurement, specifically a real-time measurement and analysis device for forest tree diameter. Background Technology

[0002] In forestry resource monitoring and forest ecology research, tree diameter is a core indicator for assessing tree growth dynamics, biomass estimation, and the health of forest ecosystems. Traditional tree diameter measurement mainly relies on manual use of tools such as calipers and circumference measuring tapes to obtain data through regular field measurements. This method is not only labor-intensive and inefficient, but also susceptible to human error and long measurement cycles, making it difficult to meet the needs for real-time and continuous monitoring of tree growth processes.

[0003] With the development of automation technology, some measuring devices have achieved automatic monitoring of diameter changes by installing sensors on the surface of trees. However, the existing devices have a simple fixed structure design, which makes it difficult to adapt to trees with different diameters at breast height. The devices have a low degree of integration, and the data processing and transmission modules are mostly external or separate designs. Therefore, we propose a real-time measurement and analysis device for tree diameter. Utility Model Content

[0047] Adjusting rod 6: rod-shaped, with a T-shaped groove 11 on one side, and both ends can be inserted into the square slots of the L-shaped frame 3. Under the action of spring 2 10, the position is finely adjusted to adapt to trees with different diameters at breast height. It has an embedded data processing and transmission unit.

[0048] Movable plate 7: Plate-shaped, with a T-shaped slider 17 connected to one side and a strip hole for installing a limiting rod 18, corresponding to the fixed plate 4, and connected to the other end of the measuring belt 5, which drives the displacement sensor 8 to move when the diameter of the trees changes;

[0049] Displacement sensor 8: A small electronic component, fixed on the movable plate 7, which monitors the displacement of the movable plate 7 in real time and converts the displacement change into an electrical signal;

[0050] Spring 9: Helical, connecting movable plate 7 and L-shaped frame 3, providing pre-tension to measuring belt 5 to ensure it fits tightly against the tree trunk;

[0051] Spring 210: Helical shape, connecting the adjusting rod 6 and the L-shaped frame 3, allowing the adjusting rod 6 to be finely adjusted in the square groove to adapt to trees with different diameters at breast height;

[0052] T-shaped groove 11: A groove structure with a "T" shaped cross section, opened on the adjusting rod 6, and cooperates with the T-shaped slider 17 of the movable plate 7 to guide the movement of the movable plate 7 and restrict its direction of movement;

[0053] Strip hole 12: A long strip-shaped through hole, opened on the L-shaped frame 3, corresponding to the T-shaped slide groove 11, for the T-shaped slider 17 of the movable plate 7 to slide, so that the movable plate 7 can move with the measuring belt 5;

[0054] Hemispherical groove 13: A hemispherical groove, equidistantly distributed along the inner wall axis of sleeve 1, engages with the hemispherical protrusion 16 of lifting rod 2 to fix the adjusted height of lifting rod 2;

[0055] Circular groove 14: A circular groove, equidistantly distributed along the axis of the outer cylindrical surface of the lifting rod 2, to accommodate the spring 15 and the hemispherical protrusion 16, and to cooperate with the hemispherical groove 13 to realize the height adjustment and locking of the lifting rod 2;

[0056] Spring 3 15: Helical shape, installed in the circular groove 14, pushes the hemispherical protrusion 16 to engage with the hemispherical groove 13 on the inner wall of the sleeve 1, and maintains the fixed state of the lifting rod 2;

[0057] Hemispherical protrusion 16: A hemispherical protrusion that engages with the hemispherical groove 13 on the inner wall of the sleeve 1 under the action of spring 3 15, thereby locking the height of the lifting rod 2;

[0058] T-shaped slider 17: A block structure with a "T" shaped cross-section, connecting the movable plate 7 with the strip hole 12 and the T-shaped groove 11, guiding the movable plate 7 to slide in a fixed direction;

[0059] Limiting rod 18: rod-shaped, fixed in the slot of the movable plate 7, used to clamp the other end of the measuring belt 5 to prevent it from falling off.

[0060] Working principle: During installation, the operator inserts the conical tip of the sleeve 1 of the outrigger adjustment structure into the soil on one side of the tree. The friction between the conical tip and the soil initially fixes the device. Then, according to the tree height and measurement requirements, the height of the device is adjusted by lifting or lowering the lifting rod 2. During this process, the hemispherical protrusion 16 on the outer cylindrical surface of the lifting rod 2 engages with the hemispherical groove 13 on the inner wall of the sleeve 1 under the action of the spring 15. When the lifting rod 2 is adjusted to the appropriate position, the hemispherical protrusion 16 embeds into the corresponding hemispherical groove 13, completing the height locking and ensuring the measurement frame structure is secure. At a suitable measurement height, after the two L-shaped frames 3 in the measuring frame structure are fixed by the lifting rod 2, the adjusting rod 6 can be finely adjusted in the square groove of the L-shaped frame 3 under the action of the spring 10 to adapt to trees with different diameters at breast height. The fixed plate 4 and the movable plate 7 are respectively located on the two L-shaped frames 3. One end of the measuring belt 5 is fixed to the fixed plate 4, and the other end is clamped to the movable plate 7 by the limiting rod 18. When the measuring belt 5 wraps around the tree trunk, the change in the tree diameter will push the movable plate 7 to slide along the strip hole 12, and the T-shaped slider 17 moves synchronously in the T-shaped groove 11. Spring 9 provides preload to the measuring belt 5, ensuring it remains tightly fitted to the tree trunk surface. This design allows the measuring belt 5 to adapt to changes in tree diameter, avoiding measurement errors caused by gaps. Displacement sensor 8 is fixed to the movable plate 7. When the tree diameter changes, the measuring belt 5 displaces accordingly, causing the movable plate 7 to move. Displacement sensor 8 senses the displacement of the movable plate 7 in real time. This displacement is linearly related to the change in tree diameter. Displacement sensor 8 converts the displacement change into an electrical signal, which is transmitted through internal circuitry to the data processing and transmission unit embedded in the adjusting rod 6. After receiving the electrical signal from displacement sensor 8, the data processing and transmission unit first performs preprocessing such as filtering and amplification to remove noise interference. Then, based on a preset mathematical model, it converts the electrical signal into corresponding tree diameter data. The processed data is stored in the unit's storage module and transmitted in real time to a remote data center via a wireless communication module. Forestry workers can remotely view and analyze real-time data and growth trends of tree diameter through the data center's management platform, providing accurate data for forest resource monitoring and management.
