Embodiment 1

[0034] Such as figure 1 As shown, a tool for measuring the DBH of a tree includes three or more measuring sides 100, and several measuring sides 100 are connected end to end to form a linear structure, and the measuring sides 100 are hinged, and the measuring sides 100 can be around the hinge point Rotation, the adjacent measuring sides 100 can be rotated to form an included angle of any size, one of the measuring sides 100 has a fixed length, and the other measuring sides 100 are telescopic structures, which can be adjusted in length.

[0035] Preferably, the measuring side 100 is a hollow structure, and the inside forms a groove with one side opening, and the thickness of several measuring sides 100 decreases successively, and the measuring side 100 with the smaller thickness among the two adjacent measuring sides 100 has a larger thickness. The groove clearance fit of the measuring side 100. When folded and folded, the measuring side 100 with a smaller thickness can be fol...

Embodiment 2

[0063] As a specific example:

[0064] Such as image 3 As shown, a tool for measuring the DBH of a tree comprises three measuring sides 100, which are respectively the first measuring side 1, the second measuring side 2, the third measuring side 3, the first measuring side 1 and the second measuring side 2 and The third measuring sides 3 are respectively hinged by pin shafts, the first measuring side 1 and the third measuring side 3 include an outer ruler 4, an inner ruler 5 and a displacement sensor 6, and one end of the outer ruler 4 is hinged with the second measuring side 2, The other end is a free end, the inner ruler 5 is arranged inside the outer ruler 4, and the outer ruler 4 is provided with a groove matching with the inner ruler 5, and the inner ruler 5 is arranged in the groove, and the first measuring side 1 and the second The hinge point of measuring side 2, the hinge point of second measuring side 2 and the third measuring side 3 are all provided with angle sen...

Embodiment 3

[0078] As a specific example:

[0079] Such as Figure 4 As shown, a tool for measuring the DBH of a tree comprises three measuring sides 100, which are respectively the first measuring side 1, the second measuring side 2, the third measuring side 3, the first measuring side 1 and the second measuring side 2 and The third measurement sides 3 are respectively hinged by pin shafts. The first measurement side 1 and the third measurement side 3 include an outer ruler 4 and an inner ruler 5. One end of the outer ruler 4 is hinged with the second measurement side 2, and the other end is free. end, the inner ruler 5 is set inside the outer ruler 4, and the outer ruler 4 is provided with a groove matching with the inner ruler 5, the inner ruler 5 is arranged in the groove, and the outer ruler 4 of the first measuring side 1 is provided with Displacement sensor 6, inner ruler 5 is connected with displacement sensor 6. The inner ruler 5 slides along the groove, extends the free end of...

Abstract

The invention relates to a tool for measuring the diameter at breast height of a tree. The tool for measuring the diameter at breast height of the tree comprises three or more measuring edges, whereinthe plurality of measuring edges are sequentially connected end to end to form a linear structure, the measuring edges are hinged, the measuring edges can rotate around hinge points, the adjacent measuring edges can rotate to form an included angle of any size, one measuring edge is of a fixed length and the other measuring edges are of a telescopic structure, and the length can be adjusted. Thetool is simple to operate and high in measurement precision, and can be used for scientific research on forest resources, forest growth and the like; the tree diameter at breast height is calculated in a mode of forming a triangle or a polygon in a plane through the measuring edges and calculating the inner diameter, and compared with a diameter-at-breast-height ruler, the measuring edges are moreeasily kept in the same plane, so that errors are reduced, and the measuring precision is improved.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a tool for measuring the diameter at breast height of trees. Background technique [0002] A set of measurement techniques and methods that take trees and forests as the main objects in forest resources investigation. Its main tasks are: ① Static and dynamic analysis of the accumulated resources of a forest area, forestry bureau or forest farm, to obtain basic data to demonstrate the possibility of timber base construction and planned harvesting volume; ② To identify the effects of various forest management measures Provide basis; ③ provide the quantity data needed for forest protection and environmental protection; ④ provide basis for afforestation and selection of afforestation tree species; ⑤ provide various necessary data for various production plans, forestry zoning and forestry planning, etc. [0003] Overview The tree measuring work with histo...
