[0021] The following is combined with Figure 1-4 This application is described in further detail.

[0022] The present application embodiment discloses a tree support device for monitoring safety and early warning. Figure 1The tree support device for monitoring safety and early warning includes a support frame 1 and a tree hoop 2. The support frame 1 includes a plurality of support rods 101, which are spaced along the circumference of the tree hoop 2. One end of the support rod 101 is hinged to the bottom wall of the tree hoop 2, and the other end is used to be fixedly installed in the soil, so that the tree hoop 2 is installed above the support frame 1. In order to improve the overall stability of the plurality of support rods 101, the support rods 101 are inclined, and the lower ends of the support rods 101 are inclined in a direction away from the center of the tree hoop 2. A reinforcement ring 28 is distributed below the plurality of support rods 101. The reinforcement ring 28 is concentrically arranged with the tree hoop 2. The lower end of the support rod 101 is hinged to the reinforcement ring 28. The reinforcement ring 28 is fixedly installed in the soil and extends into the soil 15-20 cm and is fixed; wherein the tree hoop 2 and the reinforcement ring 28 are both composed of two semicircular rings by bolts, screws or welding, so that the tree hoop 2 and the reinforcement ring 28 can be sleeved outside the tree trunk.

[0023] Reference Figure 1 and Figure 2 Specifically, the inner diameter of the tree hoop 2 is larger than the diameter of the trunk, the trunk is located in the tree hoop 2, and a plurality of guide rods 14 are slidably penetrated inside the tree hoop 2. The plurality of guide rods 14 are spaced apart along the circumference of the tree hoop 2, and the guide rods 14 slide radially along the tree hoop 2. An abutment plate 3 is fixed to one end of the guide rod 14 close to the center of the tree hoop 2. The abutment plate 3 is arc-shaped, and the abutment plate 3 is concentrically arranged with the tree hoop 2. The abutment plate 3 is used to abut against the trunk. An elastic member is arranged in the tree hoop 2, and the elastic member is used to push the guide rod 14 to drive the abutment plate 3 to move toward the direction close to the trunk.

[0024] 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 on the corresponding support frame 1 or the abutment plate 3. In the embodiment of the present application, the pressure sensor 4 is installed on the side of the abutment plate 3 close to the center of the tree hoop 2 to detect the pressure change on the abutment plate 3 exerted on the tree trunk; in other embodiments, the pressure sensor 4 can be provided in the middle and lower sections of the support rod 101 in the support frame 1 or on the side where the reinforcement ring 28 contacts the soil. When the support rod 101 is subjected to different forces, its bending and deformation degrees are different, and thus the pressure on the pressure sensor 4 is different, so as to facilitate the detection of the force change on the support rod 101.

[0025] Reference Figure 1 and Figure 3 A controller 5 is fixedly installed on the support rod 101 of the tree hoop 2 or the support frame 1, the pressure sensor 4 is wirelessly connected to the controller 5, and the controller 5 is wirelessly connected to the external management platform; specifically, an installation cavity 26 is opened in 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.

[0026] When in use, the support frame 1 supports the tree hoop 2, and the tree hoop 2 is sleeved outside the tree trunk. Under the action of the elastic member, the abutment plate 3 will always abut against the tree trunk to achieve a certain support for the tree; the pressure sensor 4 on the abutment plate 3 abuts against the tree trunk to detect the pressure change of the tree trunk on the abutment plate 3, and sends it to the controller 5 in real time. The controller 5 receives the pressure change value detected by the pressure sensor 4 and sends it to the external management platform regularly or in real time, and sends it to the external management platform in time when the pressure change value detected by the pressure sensor 4 exceeds the preset threshold range, so that the maintenance personnel can use the external management platform to help timely determine whether the tree is skewed or fallen, and can analyze the possibility of tree breakage based on relevant data, so as to facilitate the maintenance personnel to know the condition of the tree in time. Among them, the preset threshold range is set according to the pressure change of the abutment plate 3 before the tree trunk is skewed or fallen.

[0027] Reference Figure 1 and Figure 3 In order to facilitate the guide rod 14 to drive the abutment plate 3 to move toward the direction close to the tree trunk, the elastic member includes a spring 29. The spring 29 corresponds to the guide rod 14 one by one. 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 installation cavity 26 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, so that the spring 29 always has the potential energy to drive the guide rod 14 and the abutment plate 3 to move toward the tree trunk, so as to provide a certain support to the tree through the abutment plate 3. In other embodiments, the spring 29 can be replaced by a rubber pad arranged between the guide rod 14 and the inner wall of the installation cavity 26.

[0028] Reference Figure 2 and Figure 3A plurality of abutment plates 3 are slidably connected to a same flexible abutment belt 6 on one side close to the tree trunk. Specifically, the flexible abutment belt 6 is made of a foam belt, a silicone belt, a plastic belt, etc. with poor ductility, which is not limited here; the flexible abutment belt 6 is used to abut against the tree trunk to avoid damaging the outer bark of the trunk. The flexible abutment belt 6 covers the pressure sensor 4 so that the pressure sensor 4 abuts against the tree trunk separated by the flexible abutment belt 6. A guide strip 22 is fixed on one side of the flexible abutment belt 6 close to the abutment plate 3. The cross section of the guide strip 22 is an arc shape, and the central angle of the circle is greater than 180°. A guide groove 23 that slidably cooperates with the guide strip 22 is provided on one side of the abutment plate 3 close to the center of the tree hoop 2, so that the flexible abutment belt 6 will not be separated from the abutment plate 3; the flexible abutment belt 6 embraces the tree trunk, one end of the flexible abutment belt 6 is fixedly nailed to the tree trunk as a fixed end, and the other end is slidably set as a movable end. Specifically, the fixed end of the flexible abutment belt 6 is close to the movable end of the flexible abutment belt 6, and the movable end of the flexible abutment belt 6 extends from the surface of the abutment plate 3 toward the tree hoop 2 to ensure that the flexible abutment belt 6 can completely embrace the tree trunk; a displacement detection component is provided on the tree hoop 2, and the displacement detection component is used to detect the displacement change of the movable end of the flexible abutment belt 6, and the displacement detection component is wirelessly connected to the controller 5.

[0029] Reference Figure 3 and Figure 4 In order to detect the displacement change of the moving end of the flexible abutting belt 6, the displacement detection part 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 fixed to the bottom wall of the tree hoop 2 by bolts. The mounting box 7 is located below the flexible abutting belt 6. A guide ruler 24 is fixed inside the mounting box 7. The guide ruler 24 is arranged in the vertical direction. The slider 8 is slidably sleeved on the guide ruler 24 in the mounting box 7. The connecting rope 9 is inelastic. One end of the connecting rope 9 is fixed to the upper surface of the slider 8, and the other end slides out of the mounting box 7 and is connected to the moving end of the flexible abutting belt 6. In connection, a plurality of guide pulleys 25 are fixedly installed inside the installation box 7 and on the outer wall of the installation box 7. The connecting rope 9 between the moving end of the flexible abutting belt 6 and the slider 8 slides and overlaps on the plurality of guide pulleys 25 in sequence, guiding the movement of the connecting rope 9 to adapt to the height of the flexible abutting belt 6, so that the movement of the flexible abutting 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 installation box 7, and the other end is fixed to the lower surface of the slider 8. The elastic rope 10 has a pulling force on the slider 8 toward the connecting rope 9, so that the connecting rope 9 and the flexible abutting belt 6 are kept 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.

[0030] When the tree grows and its diameter increases, the change in the circumference of the tree will stretch the flexible abutment belt 6, and at the same time push the abutment plate 3 to slide in the direction away from the tree hoop 2. When the flexible abutment belt 6 is stretched, relative sliding occurs between the multiple abutment plates 3, and then the moving end slides, causing the flexible abutment belt 6 to pull the connecting rope 9, and the connecting rope 9 pulls the slider 8 to move toward the side close to the connecting rope 9, stretching the elastic rope 10. At this time, the displacement of the slider 8 is detected by the displacement sensor 11 on the slider 8 and sent to the controller 5 in real time or at a fixed time. The controller 5 reports the data detected by the displacement sensor 11 to the external management platform in real time or at a fixed time, so that maintenance personnel can obtain the changes in tree diameters, which helps to monitor and analyze the growth conditions of trees according to the corresponding data.

[0031] Reference Figure 1 and Figure 3 An alarm 13 is installed on the support frame 1 or the 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 time, thereby conveniently notifying passers-by to avoid casualties.

[0032] Reference Figure 2 and Figure 3 A pest sensor 12 for detecting tree pests is fixedly installed on the upper end of the abutment plate 3. The pest sensor 12 is wirelessly connected to the controller 5. Specifically, the pest sensor 12 can be a multi-spectral camera sensor, an ultrasonic sensor, a biosensor, etc., and there is no specific limitation. When in use, the pest sensor 12 on the abutment plate 3 can detect the pests of the tree and send it to the controller 5. The controller 5 sends the pest detection data to the external management platform in real time or at a fixed time, so that the maintenance personnel can know the status of the tree in time to determine whether the tree has pests.

[0033] Reference Figure 1 and Figure 3 A removable battery (not shown) is built into the support frame 1 or the tree hoop 2. The pressure sensor 4, the displacement sensor 11, the controller 5, the alarm 13 and the pest sensor 12 are all electrically connected to the battery. Specifically, the battery is built into the tree hoop 2 to protect the battery. The pressure sensor 4, the displacement sensor 11, the controller 5, the alarm 13 and the pest sensor 12 are powered by the removable battery to ensure continuous and repeated use of the device.

[0034] Reference Figure 3 and Figure 4A fixed rack 15 is fixed on the guide rod 14, and the length direction of the fixed rack 15 is parallel to the length direction of the corresponding guide rod 14. A limit rack 16 is slidably arranged in the installation cavity 26 of the tree hoop 2, and the limit rack 16 corresponds to the fixed rack 15 one by one. The limit rack 16 is located above the corresponding fixed rack 15, and the sliding direction of the limit rack 16 is parallel to the axial direction of the tree hoop 2. The limit rack 16 is slidably matched with the guide rail (not shown in the figure) on the inner wall of the installation cavity 26 through the guide block to guide the sliding of the limit rack 16; the limit rack 16 is used to mesh with the corresponding fixed rack 15, and a driving assembly is arranged in the installation cavity 26, and the driving assembly is used to drive the limit rack 16 to slide in a direction close to or away from the corresponding fixed rack 15. When the limiting rack 16 moves toward the direction close to the corresponding fixed rack 15 and engages with the corresponding fixed rack 15, the positions of the guide rod 14 and the abutment plate 3 are limited, so as to provide rigid support to the tree trunk in time.

[0035] Reference Figure 3 and Figure 4 In order to facilitate driving the limiting rack 16 to slide in a direction close to or away from the corresponding fixed rack 15, the driving component includes a wind wheel 17, a transmission member and a reset member. A plurality of wind wheels 17 are provided. The plurality of wind wheels 17 are rotated at intervals along the circumference of the tree hoop 2 and are penetrated on the outer wall of the tree hoop 2. The wind wheel 17 rotates along the radial direction of the tree hoop 2. The transmission member is arranged in the installation cavity 26. The transmission member is used to drive the plurality of limiting racks 16 to slide synchronously in a direction close to or away from the corresponding fixed rack 15 when any one or more wind wheels 17 rotate. The reset member is arranged in the installation cavity 26. The reset member is used to drive the wind wheel 17 to rotate for reset. When the wind wheel 17 is rotated by the wind, the transmission member drives the plurality of limiting racks 16 to slide in a direction close to the corresponding fixed rack 15. This helps to timely limit the position of the guide rod 14 and the abutment plate 3, enhance the supporting force, and prevent the tree trunk from being easily shaken by the wind.

[0036] Reference Figure 3 and Figure 4In order to facilitate the rotation of any one or more wind wheels 17 to drive multiple limit racks 16 to slide synchronously in the direction close to or away from the corresponding fixed racks 15, the transmission member includes a bevel gear ring 18, a bevel gear 19 and a transmission ring 20. The bevel gear ring 18 is rotatably connected in the installation cavity 26. The bevel gear ring 18 is concentrically arranged with the tree hoop 2. The rotation axis of the bevel gear ring 18 is parallel to the axial direction of the tree hoop 2. 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 wheel 17. The transmission rod 27 is located in the installation cavity 26. A bevel gear is fixedly sleeved on the transmission rod 27. Wheel 19, bevel gear 19 meshes with bevel gear ring 18, transmission ring 20 is slidably arranged in the installation cavity 26, the sliding direction of transmission ring 20 is parallel to the sliding direction of limit rack 16, transmission ring 20 and bevel gear ring 18 are arranged concentrically, transmission ring 20 is located between bevel gear ring 18 and limit rack 16, the upper surfaces of multiple limit racks 16 are fixedly connected with transmission ring 20, under the sliding cooperation between the guide block of limit rack 16 and the guide rail of the inner wall of installation cavity 26, transmission ring 20 can only move axially of tree hoop 2, transmission ring 20 is threadedly sleeved on the lower end of bevel gear ring 18. Among them, bevel gear ring 18 and transmission ring 20 are both composed of two semicircular parts by bolts, screws, welding and the like, so as to be sleeved on 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 the bevel gear 19 drives bevel gear ring 18 to rotate in the same direction.

[0037] Reference Figure 3 and Figure 4 In order to facilitate the rotation of the wind wheel 17 for resetting, the resetting member includes a resetting torsion spring 21, which corresponds to the wind wheel 17 one by one. The resetting torsion spring 21 is sleeved on the shaft of the corresponding wind wheel 17, one end of the resetting torsion spring 21 is fixed on the inner wall of the mounting cavity 26, and the other end is fixed on the shaft of the wind wheel 17. The torsion 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 a natural state, the limiting rack 16 is disengaged from the corresponding fixed rack 15.

[0038] When strong wind blows, it will not only make the trees shake, but also make one or more wind wheels 17 on the tree hoop 2 rotate, causing the corresponding reset torsion spring 21 to deform. When the wind wheel 17 rotates, it will drive the corresponding transmission rod 27 and bevel gear 19 to rotate, and 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 is rotated to drive the transmission ring 20 to move toward the direction close to the fixed rack 15, so that the limiting rack 16 gradually approaches the corresponding fixed rack 15 until the limiting rack 16 is meshed 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 rigidly supports the tree trunk, making it difficult for the tree to shake, reducing the possibility of the tree tilting 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 wheel 17 to rotate in the opposite direction, so that the bevel gear 19 drives the bevel gear ring 18 to rotate in the opposite direction, and the bevel gear ring 18 drives the transmission ring 20 to move in the direction away from the fixed rack 15, so that the limiting rack 16 is disengaged from the fixed rack 15, thereby restoring the elastic support for the tree.

[0039] The implementation principle of the embodiment of the present application is as follows: when 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 the multiple support rods 101, the tree hoop 2 is concentrically arranged with the tree trunk, and the support frame 1 supports the tree hoop 2. At this time, the reset spring 29 is in a natural state, and the limit rack 16 and the corresponding fixed rack 15 are in a disengaged state; under the pushing action of the spring 29, the abutment plate 3 will make the flexible abutment belt 6 always abut against the tree trunk to achieve a certain support for the tree; the pressure sensor 4 on the abutment plate 3 abuts against the tree trunk separated by the flexible abutment belt 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 regularly or in real time, and 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 time, and the maintenance personnel can use the external management platform to help timely determine whether the tree is skewed or fallen, and can analyze the possibility of tree breakage according to relevant data, so as to enable the maintenance personnel to know the condition of the tree in time.

[0040] When the tree grows and its diameter increases, the tree will stretch out the flexible abutment belt 6 and push the abutment plate 3 to slide in the direction away from the tree hoop 2. When the flexible abutment belt 6 is stretched out, its moving end moves, pulling the connecting rope 9. The connecting rope 9 pulls the slider 8 to move toward the side close to the connecting rope 9. The displacement of the slider 8 is detected by the displacement sensor 11 on the slider 8 and sent to the controller 5 in real time or at a fixed time. The displacement value detected by the displacement sensor 11 is received by the controller 5 and sent to the external management platform in real time or at a fixed time, so that the maintenance personnel can obtain the change of the tree diameter, which is helpful to judge the growth condition of the tree according to the corresponding data. At the same time, The pest sensor 12 can detect pests and diseases on trees and send them to the controller 5. The controller 5 can send the pest and disease detection data to the external management platform in real time or at a fixed time, so that maintenance personnel can promptly determine whether the trees have pests and diseases; maintenance personnel can remotely monitor and promptly determine the condition of the trees, and send maintenance personnel to conduct on-site inspections when necessary; the device realizes cloud management and data interaction of garden maintenance agencies, provides a tree support device with digital monitoring and data uploading, can monitor the condition of trees and issue timely warnings when encountering danger, saves manpower investment, and improves the efficiency and technology of garden maintenance.

[0041] 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.
