Description

Technical Field

[0001] The utility model relates to the technical field of measurement, in particular to a device for measuring and calculating the annual growth of trees. Background Art

[0002] With the development of society and people's attention to environmental protection, the monitoring and measurement of forest growth has become a vital task in forest management and ecological protection. Understanding the annual growth of trees is of great significance for scientific and reasonable forest management, maintenance of ecological balance and sustainable use of wood resources. The measurement of annual growth of trees is crucial for forest resource management and ecosystem monitoring. Understanding the growth of trees can help decision makers take appropriate measures to ensure the health and sustainable use of forests.

[0003] After searching, the existing patent (publication number: CN219810347U) discloses a forestry tree distance measuring ruler, including: a tape measure body; the tape measure body includes a cavity and a tape measure located inside the cavity; a binding component, the binding component is arranged at the free end of the tape measure, and is used to fix the free end of the tape measure to the measuring tree. When the utility model is in use, when it is necessary to measure the tree distance, the binding straps 1 and 2 on both sides are pulled out to the outside of the chamber, and the tree trunk is surrounded by the binding straps 1 and 2. At this time, the disc spring 1 and the disc spring 2 are stretched, and then the hook on the second connecting head is matched with the slot on the first connecting head, so that the binding straps 1 and 2 can be limited to fix the tree trunk, thereby facilitating the measurement of the tree distance. When the measurement is completed, the hook and the slot are unlocked. At this time, the binding straps 1 and 2 will shrink to the inside of the chamber under the action of the disc springs 1 and 2, so as to facilitate use.

[0004] However, in actual use of the above solution, due to the complex structure, the use environment of the device is relatively complex, and there are more impurities. Compared with more sophisticated devices, the internal structure may be stuck due to impurities, affecting the normal use of the device.

[0005] In view of this, the utility model proposes a device for measuring the annual growth of trees. Utility Model Content

[0008] Preferably, the card slot is slidably connected to the graduated ruler, and the card slot is snap-connected to the buckle.

[0009] Preferably, a connecting frame is fixedly connected to the bottom end of the measuring tape, and a rotating shaft is fixedly connected to the inner side of the bottom end of the connecting frame.

[0010] Preferably, a winding wheel is rotatably connected to the outer side of the middle end of the rotating shaft.

[0011] Preferably, a measuring rope is provided on the outer side of the winding wheel, and a counterweight block is fixedly connected to the bottom end of the measuring rope.

[0012] Preferably, an anti-slip cover which is opposite to the upper and lower parts is fixedly connected to the outer side of the measuring tape, and a fitting plate is fixedly connected to the rear side of the anti-slip cover.

[0013] Preferably, the laminating plate is fixedly connected to the anti-slip sleeve.

[0014] Preferably, the left side of the measuring tape is slidably connected to a limit plate, and the limit plate is snap-connected to the graduated ruler.

[0015] The working principle and beneficial effects of the utility model are:

[0016] 1. In the present invention, the device is fixed by engaging the buckle with the base, the limit rod and the slot, so that it is convenient to use during use, and the device has a simple structure, which reduces the failure rate during use. At the same time, a device with a simple structure usually means lower manufacturing and maintenance costs. A simpler design usually requires less materials and components, which reduces the cost of manufacturing and maintenance, making the device more cost-effective;

[0017] 2. In the utility model, the measuring rope and the counterweight block are used to measure the measuring height by the length of the measuring rope, thereby avoiding the difference in the measuring data caused by the different measuring heights each time, resulting in a large error between the final measuring data and the actual data. By fixing the measuring height, it can ensure that the trees of the same height are measured at different times and places, thereby improving the consistency and comparability of the measuring results. This is crucial for long-term growth trend analysis and comparison. BRIEF DESCRIPTION OF THE DRAWINGS
