The support frame is fixedly installed in the soil, and the tree hoops are placed on the support frame and fitted onto the tree trunk. The support device composed of the support frame and tree hoops can support the tree. However, because maintenance personnel cannot always be on-site to inspect the trees, they cannot know the condition of the trees in a timely manner. Summary of the Invention

[0023] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0024] This application discloses a tree support device for monitoring safety and providing early warning. (Refer to...) Figure 1 The tree support device for monitoring safety and early warning includes a support frame 1 and a tree hoop 2. The support frame 1 includes multiple support rods 101, which are spaced apart circumferentially along the tree hoop 2. One end of each support rod 101 is hinged to the bottom wall of the tree hoop 2, and the other end is fixedly installed in the soil, so that the tree hoop 2 is installed above the support frame 1. To improve the overall stability of the multiple support rods 101, the support rods 101 are inclined, with the lower end of each support rod 101 tilted away from the center of the tree hoop 2. Reinforcing rings 28 are distributed below the multiple support rods 101, and the reinforcing rings 28 are concentrically arranged with the tree hoop 2. The lower end of each support rod 101 is hinged to the reinforcing ring 28, which is fixedly installed in the soil and extends 15-20 cm into the soil for fixation. Both the tree hoop 2 and the reinforcing ring 28 are composed of two semi-circular rings connected by bolts, screws, or welding, allowing the tree hoop 2 and the reinforcing ring 28 to be fitted over the tree trunk.

[0025] Reference Figure 1 and Figure 2 Specifically, the inner diameter of the tree hoop 2 is larger than the diameter of the tree trunk. The tree trunk is located inside the tree hoop 2. Multiple guide rods 14 are slidably inserted through the inner side of the tree hoop 2. The multiple guide rods 14 are distributed at intervals along the circumference of the tree hoop 2. The guide rods 14 slide along the radial direction of the tree hoop 2. An abutment plate 3 is fixed at one end of the guide rod 14 near the center of the tree hoop 2. The abutment plate 3 is arc-shaped and is concentrically set with the tree hoop 2. The abutment plate 3 is used to abut against the tree trunk. An elastic element is provided inside the tree hoop 2. The elastic element is used to push the guide rods 14 to move the abutment plate 3 toward the direction closer to the tree trunk.

[0026] Reference Figure 1 and Figure 3 A pressure sensor 4 is provided on the support frame 1 or the abutment plate 3. The pressure sensor 4 is used to detect the pressure change of the corresponding support frame 1 or abutment plate 3. In this embodiment, the pressure sensor 4 is installed on the side of the abutment plate 3 near the center of the tree hoop 2 to detect the pressure change of the abutment plate 3 on the tree trunk. In other embodiments, the pressure sensor 4 can be set in the middle and lower section of the support rod 101 in the support frame 1 or on the side of the reinforcing ring 28 that is in contact with the soil. Since the support rod 101 bends and deforms differently when it is subjected to different forces, the pressure on the pressure sensor 4 is different, so as to detect the force change of the support rod 101.

[0027] Reference Figure 1 and Figure 3 A controller 5 is fixedly installed on the support rod 101 of the tree hoop 2 or support frame 1. The pressure sensor 4 is wirelessly connected to the controller 5, and the controller 5 is wirelessly connected to an external management platform. Specifically, an installation cavity 26 is opened inside the tree hoop 2, and the controller 5 is installed in the installation cavity 26 of the tree hoop 2 to protect the controller 5.

[0028] In use, the support frame 1 supports the tree hoop 2, which is fitted over the tree trunk. The abutment plate 3, under the action of the elastic element, remains in contact with the tree trunk, providing support. The pressure sensor 4 on the abutment plate 3 detects changes in pressure from the trunk against the abutment plate 3 and sends this information to the controller 5 in real time. The controller 5 receives the pressure change values ​​detected by the pressure sensor 4 and sends them to an external management platform periodically or in real time. It also sends a timely message to the external management platform when the pressure change value detected by the pressure sensor 4 exceeds a preset threshold range. This allows maintenance personnel to promptly determine whether trees are leaning or falling, and to analyze the likelihood of tree breakage based on relevant data, thus facilitating timely awareness of the tree's condition. The preset threshold range is set based on the pressure changes on the abutment plate 3 before the tree trunk leans or falls.

[0029] Reference Figure 1 and Figure 3 To facilitate the movement of the guide rod 14 and the abutment plate 3 towards the tree trunk, an elastic element includes a spring 29. Each spring 29 corresponds to one of the guide rods 14, and the spring 29 is sleeved on the corresponding guide rod 14. One end of the spring 29 is fixed to the inner wall of the mounting cavity 26 on the side away from the tree trunk, and the other end is fixed to the guide rod 14. When the abutment plate 3 abuts against the tree trunk, the spring 29 is in a compressed state, ensuring that the spring 29 always possesses the potential energy to drive the guide rod 14 and the abutment plate 3 towards the tree trunk, thus providing some support to the tree through the abutment plate 3. In other embodiments, the spring 29 can be replaced by a rubber pad disposed between the guide rod 14 and the inner wall of the mounting cavity 26.

[0030] Reference Figure 2 and Figure 3Multiple abutment plates 3 are slidably connected to the same flexible abutment strip 6 on the side near the tree trunk. Specifically, the flexible abutment strip 6 is made of one of the following materials with poor extensibility: foam strip, silicone strip, plastic strip, etc., without limitation. The flexible abutment strip 6 is used to abut against the tree trunk to avoid damaging the bark of the tree trunk. A flexible abutment band 6 covers the pressure sensor 4, allowing the pressure sensor 4 to abut against the tree trunk through the flexible abutment band 6. A guide strip 22 is fixed to the side of the flexible abutment band 6 near the abutment plate 3. The cross-section of the guide strip 22 is arc-shaped, and the central angle is greater than 180°. A guide groove 23 is provided on the side of the abutment plate 3 near the center of the tree band 2, which slides with the guide strip 22 to prevent the flexible abutment band 6 from detaching from the abutment plate 3. The flexible abutment band 6 wraps around the tree trunk. One end of the flexible abutment band 6 is fixed to the tree trunk as a fixed end, and the other end is slidably configured as a movable end. Specifically, the fixed end of the flexible abutment band 6 is close to the movable end of the flexible abutment band 6, and the movable end of the flexible abutment band 6 extends from the surface of the abutment plate 3 toward the tree band 2 to ensure that the flexible abutment band 6 can completely wrap around the tree trunk. A displacement detection element is provided on the tree band 2 to detect the displacement change of the movable end of the flexible abutment band 6. The displacement detection element is wirelessly connected to the controller 5.

[0031] Reference Figure 3 and Figure 4 To facilitate the detection of displacement changes at the moving end of the flexible abutment belt 6, the displacement detection component includes a mounting box 7, a slider 8, a connecting rope 9, an elastic rope 10, and a displacement sensor 11. The mounting box 7 is bolted to the bottom wall of the tree hoop 2 and is located below the flexible abutment belt 6. A guide ruler 24 is fixed inside the mounting box 7 and is set vertically. The slider 8 is slidably fitted onto the guide ruler 24 inside the mounting box 7. The connecting rope 9 is non-elastic, with one end fixed to the upper surface of the slider 8 and the other end sliding through the mounting box 7 to connect with the moving end of the flexible abutment belt 6. Multiple guide pulleys 25 are fixedly installed inside and on the outer wall of the mounting box 7. The connecting rope 9 between the moving end of the flexible abutment belt 6 and the slider 8 slides and overlaps on the multiple guide pulleys 25 in sequence, guiding the movement of the connecting rope 9 to adapt to the height of the flexible abutment belt 6, so that the movement of the flexible abutment belt 6 can be reflected as the movement of the connecting rope 9. One end of the elastic rope 10 is fixed to the bottom wall of the mounting box 7, and the other end is fixed to the lower surface of the slider 8. The elastic rope 10 exerts a pulling force on the slider 8 towards the connecting rope 9, thereby keeping the connecting rope 9 and the flexible abutment belt 6 taut. The displacement sensor 11 is installed on the slider 8. The displacement sensor 11 is used to measure the displacement of the slider 8. The displacement sensor 11 is wirelessly connected to the controller 5.

[0032] As trees grow and their diameter increases, the change in tree circumference expands the flexible abutment belt 6, simultaneously pushing the abutment plate 3 to slide away from the tree hoop 2. When the flexible abutment belt 6 is expanded, relative sliding occurs between multiple abutment plates 3, which in turn causes the moving end to slide, causing the flexible abutment belt 6 to pull the connecting rope 9. The connecting rope 9 pulls the slider 8 to move towards the side closer to the connecting rope 9, stretching the elastic rope 10. At this time, the displacement sensor 11 on the slider 8 detects the displacement of the slider 8 and sends it to the controller 5 in real time or at regular intervals. The controller 5 then reports the data detected by the displacement sensor 11 to the external management platform in real time or at regular intervals, thus facilitating maintenance personnel to obtain information on changes in tree diameter and helping to monitor and analyze the tree growth status based on the corresponding data.

[0033] Reference Figure 1 and Figure 3 An alarm 13 is installed on the support frame 1 or tree hoop 2. The alarm 13 is wirelessly connected to the controller 5. Specifically, the alarm 13 is installed on one of the support rods 101 of the support frame 1. The alarm 13 can be a speaker. When the pressure change value detected by the pressure sensor 4 received by the controller 5 exceeds the preset threshold range, the controller 5 controls the alarm 13 to issue an alarm in a timely manner, thereby conveniently alerting passersby and avoiding injury or death.

[0034] Reference Figure 2 and Figure 3 A pest and disease sensor 12 for detecting tree pests and diseases is fixedly installed on the upper end of the abutment plate 3. The pest and disease sensor 12 is wirelessly connected to the controller 5. Specifically, the pest and disease sensor 12 can be one of the following: a multispectral camera sensor, an ultrasonic sensor, a biosensor, etc., without any specific limitation. In use, the pest and disease sensor 12 on the abutment plate 3 can detect tree pests and diseases and send the data to the controller 5. The controller 5 then sends the pest and disease detection data to an external management platform in real time or at regular intervals, so that maintenance personnel can know the status of the trees in a timely manner and determine whether pests and diseases have appeared.

[0035] Reference Figure 1 and Figure 3 A replaceable battery (not shown in the figure) is built into the support frame 1 or the tree hoop 2. The pressure sensor 4, displacement sensor 11, controller 5, alarm 13, and pest sensor 12 are all electrically connected to the battery. Specifically, the battery is built into the tree hoop 2 for protection. The pressure sensor 4, displacement sensor 11, controller 5, alarm 13, and pest sensor 12 are powered by the replaceable battery to ensure continuous and repeated use of the device.

[0036] Reference Figure 3 and Figure 4A fixed rack 15 is fixed on the guide rod 14. The length direction of the fixed rack 15 is parallel to the length direction of the corresponding guide rod 14. A limiting rack 16 is slidably arranged in the mounting cavity 26 of the tree hoop 2. The limiting rack 16 corresponds one-to-one with the fixed rack 15. The limiting rack 16 is located above the corresponding fixed rack 15. The sliding direction of the limiting rack 16 is parallel to the axis of the tree hoop 2. The limiting rack 16 slides in cooperation with the guide rail (not shown in the figure) on the inner wall of the mounting cavity 26 through the guide block to guide the sliding of the limiting rack 16. The limiting rack 16 is used to mesh with the corresponding fixed rack 15. A driving assembly is provided in the mounting cavity 26. The driving assembly is used to drive the limiting rack 16 to slide in a direction closer to or away from the corresponding fixed rack 15. When the limiting rack 16 moves toward the direction of the corresponding fixed rack 15, so that the limiting rack 16 meshes with the corresponding fixed rack 15, the position of the guide rod 14 and the abutment plate 3 is limited, so as to provide timely rigid support for the tree trunk.

[0037] Reference Figure 3 and Figure 4 To facilitate the sliding of the limiting rack 16 toward or away from the corresponding fixed rack 15, the drive assembly includes a windmill 17, a transmission component, and a reset component. Multiple windmills 17 are provided, rotating at intervals along the circumference of the tree hoop 2 and passing through the outer wall of the tree hoop 2. The windmills 17 also rotate radially along the tree hoop 2. The transmission component is located within the mounting cavity 26 and is used to drive multiple limiting racks 16 to slide synchronously toward or away from the corresponding fixed rack 15 when any one or more windmills 17 rotate. The reset component is located within the mounting cavity 26 and is used to drive the windmills 17 to rotate and reset. When the windmills 17 rotate due to wind force, the transmission component drives multiple limiting racks 16 to slide toward or away from the corresponding fixed rack 15. This helps to promptly limit the position of the guide rod 14 and the abutment plate 3, enhances the support force, and prevents the tree trunk from swaying due to wind force.

[0038] Reference Figure 3 and Figure 4To facilitate the simultaneous sliding of multiple limiting racks 16 toward or away from their corresponding fixed racks 15 when any one or more wind turbines 17 rotate, the transmission components include a bevel gear ring 18, a bevel gear 19, and a transmission ring 20. The bevel gear ring 18 is rotatably connected within the mounting cavity 26 and is concentrically arranged with the tree hoop 2. The rotation axis of the bevel gear ring 18 is parallel to the axis of the tree hoop 2, and the bevel gear ring 18 is located above the guide rod 14. A transmission rod 27 is coaxially fixed on the shaft of the wind turbine 17 and is located within the mounting cavity 26. A bevel gear is fixedly sleeved on the transmission rod 27. Wheel 19, bevel gear 19 meshes with bevel gear ring 18, and transmission ring 20 is slidably disposed in mounting cavity 26. The sliding direction of transmission ring 20 is parallel to the sliding direction of limiting rack 16. Transmission ring 20 and bevel gear ring 18 are concentrically arranged. Transmission ring 20 is located between bevel gear ring 18 and limiting rack 16. The upper surfaces of multiple limiting racks 16 are fixedly connected to transmission ring 20. With the sliding cooperation between the guide block of limiting rack 16 and the guide rail of the inner wall of mounting cavity 26, transmission ring 20 can only move axially upwards in the tree hoop 2. Transmission ring 20 is threaded onto the lower end of bevel gear ring 18. Both bevel gear ring 18 and transmission ring 20 are composed of two semicircular parts connected by bolts, screws, welding, etc., to facilitate fitting onto the tree trunk. When any wind wheel 17 is blown by wind and rotates, the corresponding transmission rod 27 drives bevel gear 19 to rotate, and bevel gear 19 drives bevel gear ring 18 to rotate in the same direction.

[0039] Reference Figure 3 and Figure 4 To facilitate the rotation of the impeller 17 for resetting, a resetting component includes a resetting torsion spring 21. Each resetting torsion spring 21 corresponds to one impeller 17 and is sleeved on the shaft of the corresponding impeller 17. One end of the resetting torsion spring 21 is fixed to the inner wall of the mounting cavity 26, and the other end is fixed to the shaft of the impeller 17. The torque of the resetting torsion spring 21 is greater than the rotational friction between the bevel gear 19 and the bevel gear ring 18. When the resetting torsion spring 21 is in its natural state, the limiting rack 16 disengages from the corresponding fixed rack 15.

[0040] When strong winds blow, not only will the trees sway, but one or more windmills 17 on the tree hoop 2 will also rotate, causing the corresponding return torsion spring 21 to deform. When the windmills 17 rotate, they will drive the corresponding transmission rod 27 and bevel gear 19 to rotate. The rotating bevel gear 19 will synchronously drive the bevel gear ring 18 to rotate. Since the bevel gear ring 18 is threadedly connected to the transmission ring 20, and the transmission ring 20 can only move along the axial direction of the tree hoop 2, the bevel gear ring 18 will rotate to drive the transmission ring 20 to move towards the fixed rack 15, so that the limiting rack 16 gradually approaches the corresponding fixed rack 15 until the limiting rack 16 meshes with the corresponding fixed rack 15, thereby limiting the position of the guide rod 14 and the abutment plate 3, so that the abutment plate 3 provides rigid support for the tree trunk, making the tree less likely to sway and reducing the possibility of the tree leaning or falling. When the wind force gradually decreases until it is less than the torque of the reset torsion spring 21, the deformed reset torsion spring 21 drives the wind turbine 17 to rotate in the opposite direction, causing the bevel gear 19 to drive the bevel gear ring 18 to rotate in the opposite direction. The bevel gear ring 18 drives the transmission ring 20 to move away from the fixed rack 15, causing the limiting rack 16 to disengage from the fixed rack 15, thereby restoring the elastic support for the tree.

[0041] The implementation principle of this application embodiment is as follows: In use, the reinforcing ring 28 at the lower end of the support frame 1 is installed and fixed in the soil, the tree hoop 2 is installed above multiple support rods 101, the tree hoop 2 is set concentrically with the tree trunk, the support frame 1 supports the tree hoop 2, at this time the return spring 29 is in the natural state, the limiting rack 16 is disengaged from the corresponding fixing rack 15; under the pushing action of the spring 29, the abutment plate 3 will make the flexible abutment strip 6 always abut against the tree trunk, so as to achieve a certain support for the tree; the pressure sensor 4 on the abutment plate 3 abuts against the tree trunk through the flexible abutment strip 6, thereby detecting the pressure change of the tree trunk on the abutment plate 3 and sending it to the controller 5. The controller 5 receives the pressure change value detected by the pressure sensor 4 and sends it to the external management platform at regular intervals or in real time. When the pressure change value detected by the pressure sensor 4 exceeds the preset threshold range, it is sent to the external management platform in a timely manner. The maintenance personnel can use the external management platform to help to judge in a timely manner whether the tree is tilted or fallen, and can analyze the possibility of tree breakage based on relevant data, so as to enable the maintenance personnel to know the condition of the tree in a timely manner.

[0042] As trees grow and their diameter increases, they expand the flexible abutment belt 6, simultaneously pushing the abutment plate 3 to slide away from the tree hoop 2. When the flexible abutment belt 6 is expanded, its moving end moves, pulling the connecting rope 9. The connecting rope 9 pulls the slider 8 towards the side closer to the connecting rope 9. The displacement sensor 11 on the slider 8 detects the displacement of the slider 8 and sends it to the controller 5 in real time or periodically. The controller 5 receives the displacement value detected by the displacement sensor 11 and sends it to the external management platform in real time or periodically. This allows maintenance personnel to obtain information on changes in tree diameter, helping them to judge the tree's growth status based on the relevant data. Simultaneously, through... The pest and disease sensor 12 can detect pests and diseases in trees and send the data to the controller 5. The controller 5 then sends the pest and disease detection data to an external management platform in real time or at regular intervals, so that maintenance personnel can promptly determine whether pests and diseases have appeared in the trees. This enables maintenance personnel to remotely monitor and promptly assess the condition of the trees, and dispatch maintenance personnel to conduct on-site inspections when necessary. This device realizes cloud management and data interaction for garden maintenance organizations, providing a tree support device with digital monitoring and data uploading capabilities. It can monitor the condition of trees and provide timely warnings when danger is encountered, saving manpower and improving the efficiency and technological sophistication of garden maintenance.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
