Description

Technical Field

[0001] The utility model belongs to the technical field of forestry monitoring, and in particular relates to a tree growth monitoring device for forestry carbon sink analysis. Background Art

[0002] Carbon sink refers to the process, activity or mechanism by which forest plants absorb carbon dioxide from the atmosphere and fix it in vegetation or soil, thereby reducing the concentration of the gas in the atmosphere. In the process of forestry carbon sink analysis, the tree's breast diameter data is an important data component for obtaining the biomass of the entire forest. By measuring the tree's breast diameter or tree height, the equation of biomass and tree breast diameter is used to obtain the biomass of a single tree, which is then multiplied by the number of trees per unit area of ​​each carbon layer (density per unit area) to obtain the biomass of each carbon layer. In the same way, all the measured data of the carbon layers are summed up to obtain the biomass of the project area. The carbon storage is measured by multiplying the biomass by the carbon content of the corresponding tree species, and converted into carbon dioxide equivalent based on the carbon storage.

[0003] Most of the existing tree growth monitoring devices use elastic ropes with rope buckles to determine the circumferential growth length of the tree by measuring the stretched length, and convert it into the tree's diameter at breast height. It is cumbersome to use and extremely inconvenient to disassemble and assemble. In addition, since the tree is in the process of growth, the existing tree growth monitoring device cannot accurately detect the changes in the tree's height, diameter at breast height position and size. Therefore, in order to solve the above problems, a tree growth monitoring device for forestry carbon sink analysis is proposed. Utility Model Content

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] Example 1

[0026] See also Figure 1-4 , the utility model provides a technical solution: a tree growth monitoring device for forestry carbon sink analysis, comprising a convergence component 3 and a breast diameter ruler 8 inserted into the convergence component 3;

[0027] The collecting assembly 3 includes a collecting shell 31 and a cover plate 33. A guide cavity 32 is formed on the top of the collecting shell 31. The cover plate 33 is detachably connected to the port of the guide cavity 32. A pull-out opening 35 is provided on one side of the outer wall of the collecting shell 31. A hinge shaft 36 is provided on the side of the guiding cavity 32 away from the pull-out opening 35. Specifically, both ends of the hinge shaft 36 are processed with square shaft ends. The square shaft ends at both ends of the hinge shaft 36 are respectively sunk into the inner bottom surface of the collecting shell 31 and the bottom surface of the cover plate 33. The hinge shaft 36 rotates The guide cavity 32 is connected to the drawer 35 by a hinge block 37. Two parallel positioning shafts 39 are provided on one side of the guide cavity 32 close to the drawer 35. The two positioning shafts 39 are both penetrated by a damping wheel 310. Specifically, the damping wheel 310 is a rubber wheel. The damping wheel 310 and the positioning shaft 39 are interference fit. Friction damping is formed on the fitting surface of the damping wheel 310 and the positioning shaft 39. The two ends of the damping wheel 310 respectively contact the inner bottom surface of the guide cavity 32 and the bottom surface of the cover plate 33, forming friction damping at both ends of the damping wheel 310.

[0028] A second scale 11 is provided on one end face of the breast diameter ruler 8. Specifically, the second scale 11 is used to measure the breast diameter and circumference of the tree, including scale lines, length and radius. The hinge block 37 is detachably connected to the outer end face of the breast diameter ruler 8 near the starting end of the second scale 11. The breast diameter ruler 8 between the hinge block 37 and the starting end of the second scale 11 serves as a remaining section. Specifically, the length of the remaining section is not less than 1 / 2 of the maximum outer diameter of the cover plate 33. The other end of the breast diameter ruler 8 passes around the tree and presses the remaining section, and the end is clamped by two damping wheels 310 and then passes through the pull-out opening 35.

[0029] The diameter at breast height of the tree can be measured by cooperating with the focusing component 3 and the breast-height diameter ruler 8. One end of the breast-height diameter ruler 8 is fixed by the hinge block 37 hinged in the focusing shell 31, and a remaining section is left. The free end of the breast-height diameter ruler 8 passes around the tree and presses the remaining section, and is inserted into the focusing shell 31. It is clamped by the damping wheel 310, and then the breast-height diameter of the tree is measured by the second scale 11 on the outer end face of the breast-height diameter ruler 8. In the process of tree growth, as the outer diameter of the tree changes, the circle surrounded by the breast-height diameter ruler 8 is expanded. Under the damping action of the damping wheel 310, the breast-height diameter ruler 8 can move with it, which is more convenient for measuring the breast-height diameter of the tree and more convenient to use.

[0030] Furthermore, the focusing assembly 3 also includes a guide shaft 38 parallel to the hinge shaft 36. Specifically, both ends of the guide shaft 38 are processed with square shaft ends, and the square shaft ends at both ends of the guide shaft 38 are respectively sunk into the inner bottom surface of the focusing shell 31 and the bottom surface of the cover plate 33. The guide shaft 38 guides the breast diameter ruler 8 to penetrate into the guide cavity 32. Specifically, after the free end of the breast diameter ruler 8 is pressed against the remaining section, it is bent at the guide shaft 38 and penetrated into the guide cavity 32. The breast diameter ruler 8 can be bent at a certain angle by the fixed guide shaft 38 and then introduced into the guide cavity 32. At the same time, sliding friction is formed between the outer end surface of the breast diameter ruler 8 and the outer wall of the guide shaft 38, thereby further improving the damping effect and preventing the free end of the breast diameter ruler 8 from detaching from the focusing shell 31.

[0031] Furthermore, a guide groove 9 is provided on the end face of the breast height diameter ruler 8 that contacts the tree, and a guide platform 10 is provided on the other end face of the breast height diameter ruler 8. The guide platform 10 at one end of the breast height diameter ruler 8 cooperates with the guide groove 9 at one end of the breast height diameter ruler 8 that bypasses the tree. Specifically, the second scale 11 is provided on the outer end face of the guide platform 10, and the zero scale position of the second scale 11 of the breast height diameter ruler 8 is located at the end of the remaining section. The guide groove 9 cooperates with the guide platform 10 to improve the stability of the remaining section of the breast height diameter ruler 8 and prevent the breast height diameter ruler 8 from loosening and falling off. At the same time, the guide platform 10 cooperates with the guide groove 9 to make the breast height diameter ruler close to the outer surface of the tree, so that the reading through the second scale is more accurate, thereby improving the measurement accuracy of the tree breast height diameter.

[0032] Furthermore, corresponding guide grooves 34 are provided on the inner bottom surface of the guide cavity 32 and the bottom surface of the cover plate 33. Specifically, the path formed by the guide groove 34 is located between the two damping wheels 310 and between the hinge shaft 36 and the guide shaft 38. The free end of the breast diameter ruler 8 passes through the guide cavity 32 along the guide groove 34. Specifically, one end of the breast diameter ruler 8 away from the hinge block 37 passes into the guide cavity 32 along the guide groove 34 and extends out through the pull-out opening 35. The free end of the breast diameter ruler 8 can be guided by the guide groove 34, which is more conducive to passing the free end of the breast diameter ruler 8 into the guide cavity 32.

The main tube 1 and the measuring rod 2 can be telescopically cooperated to position the convergence component 3 and the breast diameter ruler 8 at the breast diameter position 1.3 meters away from the root of the tree, so that the height change of the breast diameter position of the tree can be measured through the first scale 7, and then the height change of the tree can be obtained.

[0036] A pedal 6 is provided on the top of the ground plug 5, and the pedal 6 is convenient for the user to step on and insert the ground plug 5 into the soil, which is more convenient.

[0037] Example 3

[0038] See also Figure 1-6 , based on Example 2, the difference is that:

[0039] Furthermore, the universal joint 4 includes two relatively arranged hinged heads 41 and a cross head 42 arranged between the two hinged heads 41, and the shaft ends on the outer sides of the cross heads 42 are rotatably connected to the shaft covers 43, and the shaft covers 43 are detachably connected to the hinged heads 41.
