[0045] The outer end of the rotating shaft of the rotating sensor 3 is rotationally connected with the rope storage cylinder 9, the end of the monitoring rope 8 away from the monitoring shaft 7 is wound around the tree to be monitored and then wound to the outer end of the rope storage cylinder 9, the pitch circle diameter of the outer gear ring 5 is larger than that of the inner gear 4, so that the rotation of the monitoring shaft 7 is amplified, the outer end of the shell 1 is fixedly connected with the fixing belt 10, the end of the fixing belt 10 away from the shell 1 is wound around the tree to be monitored, and the other end of the fixing belt 10 is fixedly connected with the shell 1 through the elastic pull hook 11.

[0046] The end of the shell 1 close to the tree to be monitored is arc-shaped and matched with the tree, and the end away from the tree is also arc-shaped and matched with the circumferential surface of the tree, the diameter of the monitoring shaft 7 is smaller than that of the amplification ring 6, so that the rotation is amplified.

[0047] The shell 1 is provided with a controller, the controller is provided with a mobile power supply and a wireless communication module, and the controller is also provided with a timing module, the top end of the monitoring shaft 7 is fixedly connected with the tension spring 13, the tension spring 13 is a vortex structure, the end of the vortex structure away from the monitoring shaft 7 is fixedly connected with the inner wall of the shell 1 through the fixed plate 14, one end of the fixed plate 14 is fixedly connected with the shell 1, and the other end is rotationally connected with the outer end of the monitoring shaft 7, and the monitoring rope 8 is located between the amplification ring 6 and the fixed plate 14.

[0048] The outer end of the shell 1 is coated with a camouflage color, the outer surface of the monitoring rope 8 is provided with millimeter scale lines, the end of the fixing belt 10 away from the shell 1 is provided with a plurality of through holes matched with the fixing belt 10, the monitoring rope 8 is made of a stainless steel fine wire and has high strength and corrosion resistance, and is suitable for use in the field environment.

[0049] Working process

[0050] In use, the shell 1 is pressed to the surface of the tree to be monitored, the fixing belt 10 is wound around the tree and pulled to the direction close to the elastic pull hook 11, and then the fixing belt 10 is fixed through the elastic pull hook 11, when fixing, the appropriate through hole on the fixing belt 10 is selected to be connected with the elastic pull hook 11 according to the size of the diameter of the tree, so that the shell 1 is stably fixed on the tree.

[0051] Then, one end of the monitoring rope 8 is wound around the tree to be monitored and wound to the outer end of the rope storage cylinder 9, the tension spring 13 provides a back pulling force through the monitoring shaft 7, so that the monitoring rope 8 always adheres to the outer surface of the tree, when the tree grows, the diameter increases, the tree pulls the monitoring rope 8, the monitoring rope 8 pulls the monitoring shaft 7, the amplification ring 6 and the outer gear ring 5 to rotate, the outer gear ring 5 drives the inner gear 4 to rotate, and the inner gear 4 drives the rotating shaft of the rotating sensor 3 to rotate.

[0052] Since the pitch circle diameter of the external gear ring 5 is larger than that of the internal gear 4, the rotation is amplified twice. The diameter of the amplification ring 6 is larger than that of the monitoring shaft 7, which amplifies the pulling of the monitoring rope 8 for the first time. Through two amplifications, the minute changes in tree growth are transformed into obvious changes that can be detected by the rotation sensor 3.

[0053] Rotation sensor 3 transmits the detected rotation information to the controller, which then sends the data to the gateway via the wireless communication module to achieve real-time monitoring of tree growth.

[0054] In this embodiment, the design of the tension spring 13 and the fixing plate 14 ensures that the monitoring rope 8 always fits in close contact with the tree's surface, thus ensuring accurate monitoring of changes in the tree's diameter. The vortex structure of the tension spring 13 provides a stable pull force, preventing the monitoring rope 8 from becoming too loose and affecting the measurement accuracy.

[0055] The combination of the amplifying ring 6 and the external toothed ring 5 achieves dual amplification of minute changes in tree growth, enabling the rotation sensor 3 to accurately detect subtle changes in tree growth. Through the wireless communication module, the monitoring data can be transmitted remotely, improving the efficiency and timeliness of data collection.

[0056] The camouflage design of the housing 1 makes the device difficult to spot in the forest, preventing human interference and damage. The millimeter scale on the monitoring rope 8 facilitates initial adjustment and daily inspection during installation.
