Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tree measuring tools, in particular to an instrument for synchronously measuring the diameter at breast height and the height of a tree. Background Art
[0002] In forestry resource surveys, ecological research, and urban greening management, accurate measurement of tree diameter at breast height and tree height is an indispensable basic work. The tree diameter at breast height (i.e., trunk diameter, usually measured 1.3 meters from the ground) is an important indicator for evaluating tree growth conditions, biomass, and timber value, while tree height is directly related to the ecological function and landscape effect of trees.
[0003] Traditional tree measurement methods mostly rely on manual handheld tools, such as a diameter-at-breast (DBH) ruler and a stadiometer, to measure tree diameter at breast height (DBH) and height, respectively. However, this traditional measurement method has many drawbacks. First, the need to use two separate tools makes the measurement process cumbersome and time-consuming, reducing work efficiency. Second, because the stadiometer relies on its pole to extend and retract to reach the same height as the tree before taking the measurement, it is relatively heavy and bulky, making it difficult to carry. This is especially true when measuring a large number of trees, as each lift requires considerable effort and is inconvenient for the user. In light of this, we have proposed a simultaneous instrument for measuring both DBH and height. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0026] See also Figures 1-4 The utility model provides a technical solution: a synchronous measuring instrument for the diameter at breast height and height of a tree, comprising a slide bar 1, a surface of the slide bar 1 being provided with scale lines 10 arranged along the length direction of the slide bar 1, end plates 12 being fixedly mounted on both ends of the slide bar 1, an end of one of the end plates 12 being fixedly mounted with a limit plate 121, a sliding sleeve 14 being slidably connected to the slide bar 1, an end of the sliding sleeve 14 being fixedly mounted with a clamping plate 15, the limit plate 121 and the clamping plate 15 being clamped on the branch position of the tree, and the diameter at breast height of the tree being measured by reading the indication on the scale lines 10 indicated by the sliding sleeve 14;
[0027] Specifically, a support base 2 is fixedly installed on the other end plate 12, and a rectangular groove 20 is provided in the support base 2. A laser rangefinder 3 is rotatably connected between the left and right groove walls of the rectangular groove 20 through a rotating shaft 31. A laser light 33 is provided on the surface of the laser rangefinder 3. The laser light 33 is used to facilitate understanding of the measuring point of the laser rangefinder 3. The laser rangefinder 3 is used to measure the distance between the tree branches and the distance to the tree crown, and then the height of the tree is calculated by the Pythagorean theorem, thereby achieving the effect of facilitating measurement.
[0028] In this embodiment, the limiting plate 121 and the clamping plate 15 are both located on the same side of the sliding rod 1, and are used to clamp and fix them on the tree trunk. A transparent cover plate 11 is integrally formed on the surface of the sliding rod 1. The transparent cover plate 11 is made of transparent material, which protects the scale line 10 inside and prevents the scale line 10 from being worn.
[0029] Specifically, a measuring tape 13 is fixedly mounted on the end plate 12 near the limiting plate 121 . The unfolded length of the measuring tape 13 is between 5m and 8m, so that when encountering a tree with a large diameter at breast height, the measuring tape 13 can be used for measurement.
[0030] Furthermore, annular grooves 21 are provided on the left and right groove walls of the rectangular groove 20, and the rotating shaft 31 is located in the annular grooves 21 and is rotatably connected to the annular grooves 21; a threaded hole 22 connected to the outside world is provided on the groove wall of one of the annular grooves 21, and a fastening screw 23 is threadedly connected to the threaded hole 22, and the end of the fastening screw 23 is against the rotating shaft 31, so that the rotating shaft 31 is properly tightened, so that the rotating shaft 31 will not rotate easily without external force.
[0031] In addition, a pad 24 is fixedly installed on the front bottom wall of the rectangular groove 20. When the bottom surface of the laser rangefinder 3 is against the pad 24, the laser rangefinder 3 is horizontal and is used to horizontally measure the distance between the laser rangefinder 3 and the tree branches.
[0032] It is worth noting that a display screen 30 is provided on the surface of the laser rangefinder 3 , a protective film is provided on the surface of the display screen 30 , and the display screen 30 is used for digital display operation.
[0033] It is worth noting that a pad 32 is fixedly mounted on the upper surface of the laser rangefinder 3, and a support 34 is fixedly mounted on the bottom of the laser lamp 33. The support 34 is fixedly mounted on the pad 32 by fastening screws, which facilitates the fixed installation operation of the support 34.
[0034] When using the tree diameter at breast height and tree height synchronous measuring instrument of the present invention, the slide bar 1 is placed against the branch of the tree, and the sleeve 14 is slid so that the limit plate 121 and the clamping plate 15 are clamped on the branch. At this time, the tree diameter at breast height is measured by the number indicated on the scale line 10 by the sleeve 14; in addition, the slide bar 1 is placed at the corresponding position on the ground. At this time, the laser rangefinder 3 is first rotated to a horizontal state, and the laser rangefinder 3 is used to measure the vertical distance between the tree and the tree. Then, the angle of the laser rangefinder 3 is adjusted so that the laser rangefinder 3 measures the distance between the tree crown and the tree. At this time, the above two distances can be used as a right-angled side and a hypotenuse in a right-angled triangle, and then the length of the other right-angled side is calculated by the Pythagorean theorem. This length is the height of the tree, and the measurement operation is completed.
