[0022] The following is combined with Figure 1-3 This application is described in further detail.

[0023] The present application embodiment discloses a tree diameter monitoring instrument. Figure 1 and Figure 2 The tree diameter monitor includes a housing 1 for installation on a tree. The housing 1 includes a shell 101 and a cover plate 102. The cross section of the shell 101 is rectangular. Channel steels 14 are fixed to both ends of the shell 101 in the length direction. The shell 101 is installed on the measured tree by the cooperation of the channel steels 14 and screws. After the shell 101 is installed, the length direction of the shell 101 is parallel to the height direction of the measured tree. The cover plate 102 is detachably fixed to the shell 101 by screws, so as to open or close the shell 101 and facilitate maintenance by the operator. In other embodiments, the shell 101 and the cover plate 102 can also be detachably connected by means of locks, bolts, etc.

[0024] Reference Figure 1 and Figure 2 The bottom wall of the housing 101 is fixed with a base plate 15, the length direction of the base plate 15 is parallel to the length direction of the housing 101, a slider 2 is slidably arranged on the base plate 15, the sliding direction of the slider 2 is parallel to the length direction of the housing 101, an inelastic measuring rope 3 is fixed on one side of the slider 2, the inelastic measuring rope 3 is slidably arranged on the housing 101, the inelastic measuring rope 3 is used to extend out of the housing 101 and embrace the measured tree, and the end of the inelastic measuring rope 3 away from the slider 2 is fixed on the measured tree. In the embodiment of the present application, the inelastic measuring rope 3 is a steel wire rope; when the housing 101 is installed on the measured tree, one end of the inelastic measuring rope 3 is fixed to the upper end of the slider 2, and the other end passes through the upper end of the housing 101. A pressing plate (not shown in the figure) is fixed on the slider 2, and the pressing plate abuts against the inelastic measuring rope 3 to ensure that the inelastic measuring rope 3 is stable and not prone to tilting.

[0025] Reference Figure 2 and Figure 3, a pulling member is provided on the substrate 15, and the pulling member is used to pull the slider 2 to move in a direction away from the inelastic measuring rope 3 so that the inelastic measuring rope 3 remains tensioned, and a measuring member 4 for measuring the displacement of the slider 2 is provided on the substrate 15; a battery compartment 12 is fixed to the bottom wall of the housing 101, and the battery compartment 12 can be located on one side of the substrate 15 or below the substrate 15; a first battery 5 is installed in the battery compartment 12, and the first battery 5 is electrically connected to a solar panel 6 through a wire, and the solar panel 6 can be fixed to the ground alone or to the measured tree, and there is no limitation here. The wire between the first battery 5 and the solar panel 6 slides through the battery compartment 12 and the housing 101; the first battery 5 is electrically connected to the measuring member 4 to supply power to the measuring member 4.

[0026] When in use, the outer shell 101 is fixed to the measured tree by the cooperation of the channel steel 14 and the screws, so that the length direction of the outer shell 101 is parallel to the height direction of the tree, and the inelastic measuring rope 3 is passed through the upper end of the outer shell 101, and the inelastic measuring rope 3 is wrapped around the measured tree along the circumference of the measured tree and the end away from the slider 2 is fixed to the measured tree. Under the pulling action of the pulling member, the slider 2 exerts a pulling force on the inelastic measuring rope 3 to keep the inelastic measuring rope 3 taut, and the solar panel 6 can convert solar energy into electrical energy and store it in the first battery 5, so that the first battery 5 can supply power to the measuring member 4.

[0027] When the tree grows and its diameter increases, the change in the circumference of the tree will stretch the inelastic measuring rope 3, causing the inelastic measuring rope 3 to pull the slider 2 to slide towards the side close to the inelastic measuring rope 3. The displacement of the slider 2 is measured by the measuring piece 4, and then the change in the circumference of the measured tree can be obtained, and the change in the tree diameter can be calculated, which is convenient for the operator to analyze later; the use of the solar panel 6 can reasonably utilize solar energy and charge the first battery 5 in time, which helps to ensure the normal use of the tree diameter monitor in cold winter weather.

[0028] Reference Figure 1 and Figure 2 A second battery 7 is installed in the battery compartment 12, and the second battery 7 is electrically connected to the measuring piece 4. The second battery 7 adopts a lithium battery. By combining the lithium battery with solar power supply, dual power supply modes are realized to facilitate switching as needed, thereby further ensuring the normal use of the tree diameter monitor.

[0029] Reference Figure 2 and Figure 3In order to facilitate pulling the slider 2 to move in a direction away from the inelastic measuring rope 3 so that the inelastic measuring rope 3 remains tensioned, a mounting base 8 is fixed on the substrate 15, and the mounting base 8 is located on the side of the slider 2 away from the inelastic measuring rope 3, that is, when the shell 101 is installed on the measured tree, the mounting base 8 is located below the slider 2, and the mounting base 8 has a cylindrical section. The pulling member includes a coil spring 9, and the coil spring 9 is sleeved on the cylindrical section on the mounting base 8. The coil spring 9 is coaxially arranged with the cylindrical section, and the axial direction of the coil spring 9 is perpendicular to the length direction of the shell 101. Specifically, the axial direction of the coil spring 9 is parallel to the depth direction of the shell 101, one end of the inner ring of the coil spring 9 is fixed on the cylindrical section of the mounting base 8, and one end of the outer ring is fixed on the side of the slider 2 away from the inelastic measuring rope 3, and the coil spring 9 is located on the side of the slider 2 away from the inelastic measuring rope 3.

[0030] Reference Figure 2 and Figure 3 A pressure cap 13 is fixed on the base plate 15, and a coil spring 9 is located between the pressure cap 13 and the base plate 15. The pressure cap 13 abuts against the coil spring 9, so that the coil spring 9 is not easy to move in the direction of its own axis. Through the coiling force of the coil spring 9, the coil spring 9 always exerts a pulling force on the slider 2. When the slider 2 slides in a direction away from the mounting base 8, the slider 2 pulls the coil spring 9 to tighten; when the slider 2 slides in a direction close to the mounting base 8, the coil spring 9 expands and resets under the action of its own coiling force.

[0031] Reference Figure 2 and Figure 3 In order to facilitate the measurement of the displacement of the slider 2, the measuring member 4 includes a measuring ruler 41, a displacement sensor 42 and a circuit board 43. The measuring ruler 41 is fixed on the substrate 15, and the length direction of the measuring ruler 41 is parallel to the length direction of the housing 101. The slider 2 is slidably mounted on the measuring ruler 41, and the displacement sensor 42 is mounted on the slider 2. The measuring ruler 41, the slider 2 and the displacement sensor 42 form an electronic measuring ruler, and the displacement sensor 42 is electrically connected to the first battery 5 and the second battery 7 respectively; the circuit board 43 is mounted on the bottom wall of the housing 101, the circuit board 43 is located on one side of the substrate 15, the displacement sensor 42 is electrically connected to the circuit board 43, and the circuit board 43 is used to process and store data, and the circuit board 43 is electrically connected to the first battery 5 and the second battery 7 respectively. Specifically, in order to facilitate the staff to obtain data, one is to wirelessly connect the circuit board 43 to a gateway set in the forest, the gateway receives data through LORA and transmits it to the platform through a private network or a public network, and the staff obtains the corresponding data through the platform; wherein the gateway can correspond to multiple tree diameter detectors. Secondly, the data can be output later by connecting the data output unit on the circuit board 43 through an external data line so that the staff can obtain the data.

[0032] When in use, the displacement sensor 42 measures the displacement of the slider 2 on the measuring ruler 41 in real time or periodically and sends it to the circuit board 43 for processing and storage, so that the staff can obtain the change value of the tree diameter.

[0033] Reference Figure 2 and Figure 3 A mounting block 16 is fixed on the outer wall of the housing 101 away from the mounting base 8, and a guide wheel 10 is rotatably mounted on the side of the mounting block 16 away from the housing 101. The axial direction of the guide wheel 10 is parallel to the sliding direction of the slider 2, that is, the axial direction of the guide wheel 10 is parallel to the height direction of the tree. The guide wheel 10 is staggered with the measuring ruler 41, and the inelastic measuring rope 3 between the slider 2 and the tree is slidably overlapped on the guide wheel 10.

[0034] Reference Figure 2 and Figure 3 An idler wheel 11 is installed on the mounting block 16 through a fixing nut 17. The axial direction of the idler wheel 11 is perpendicular to the axial direction of the guide wheel 10, and the axial direction of the idler wheel 11 is parallel to the depth direction of the housing 101. The idler wheel 11 is located on the side of the guide wheel 10 close to the measuring ruler 41, and the inelastic measuring rope 3 between the guide wheel 10 and the slider 2 is slidably overlapped on the idler wheel 11.

[0035] When the housing 101 is installed on the tree to be measured, the inelastic measuring rope 3 can smoothly embrace the tree to be measured under the guidance of the idler wheel 11 and the reversing action of the guide wheel 10, ensuring the smooth movement of the inelastic measuring rope 3 and making it difficult for the inelastic measuring rope 3 to be tangled.

[0036] The implementation principle of the embodiment of the present application is as follows: when in use, the outer shell 101 is fixed to the measured tree by the cooperation of the channel steel 14 and the screws, so that the length direction of the outer shell 101 is parallel to the height direction of the tree, and the inelastic measuring rope 3 is passed through the upper end of the outer shell 101, and the inelastic measuring rope 3 is slid and overlapped on the idler wheel 11 and the guide wheel 10 in turn, and then embraced on the measured tree along the circumference of the measured tree, and the end of the inelastic measuring rope 3 away from the slider 2 is fixed to the measured tree, and under the tension of the coil spring 9, the inelastic measuring rope 3 remains taut, the solar panel 6 can convert solar energy into electrical energy and store it in the first battery 5, and the electrical energy of the first battery 5 is maintained. The first battery 5 can power the circuit board 43 and the displacement sensor 42, and the circuit board 43 and the displacement sensor 42 can also be switched to the second battery 7 for power supply as needed.

[0037] When the tree grows and the tree diameter changes, the circumference of the tree changes, which will stretch the inelastic measuring rope 3, causing the inelastic measuring rope 3 to pull the slider 2 to slide towards the side close to the inelastic measuring rope 3, or when the tree shrinks and the tree diameter becomes smaller, the tree's abutment force on the inelastic measuring rope 3 decreases, and the coil spring 9 pulls the slider 2 to slide towards the side away from the inelastic measuring rope 3. The displacement of the slider 2 is measured in real time or periodically by the displacement sensor 42 and sent to the circuit board 43 for processing and storage, so that the change in the circumference of the measured tree can be obtained, so as to calculate the change in the tree diameter, which is convenient for the operator to analyze later; the use of the solar panel 6 can reasonably utilize solar energy and charge the first battery 5 in time to ensure the power of the first battery 5, so that under the influence of cold weather in winter, although the power of the second battery 7 is attenuated, it also helps to ensure the normal use of the tree diameter monitor.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
