Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0016] Example like Figure 1 , Figure 4 and Figure 5 As shown, the device includes two symmetrically arranged support bases 10. A support block 20 is provided on the top of one end of the support base 10 that is close to each other. An arc-shaped groove is opened at one end of the support block 20 that is close to each other. Several biomimetic composite materials 21 are arranged at intervals on the side wall of the arc-shaped groove. The biomimetic composite material 21 is a 3D printed lignin composite material that gradually degrades as the tree thickens. The degradation path is pre-etched to guide the bark healing morphology, avoiding the "marking effect" of traditional support. It also includes a biomimetic support device, a support base rod 40 bolted to the support block 20, and a support strut 41 movably connected to the support base rod 40. A movable support rod 42 is connected to the outer wall of the support strut 41 via a support assembly. The bottom end of the movable support rod 42 is movably connected to the side wall of the support base rod 40. The support assembly includes a limiting groove 411 formed in the side wall of the support strut 41, and a drive motor is installed in the limiting groove 411. A lead screw 412 is installed at the output end of the drive motor, and a threaded sleeve is threadedly connected to the outer wall of the lead screw 412. 413, the outer wall of the threaded sleeve 413 is hinged to the end of the movable support rod 42, and the other outer wall of the threaded sleeve 413 is connected to the first slider 414, and the first slider 414 slides in the first slide rail 415, which is opened in the limiting groove 411; it is worth noting that the power source of the drive motor is a sensor, which monitors the support force in real time, thereby driving the drive motor to open, causing the threaded sleeve 413 to move on the lead screw 412, adjusting the support function of the support rod 41, and preventing it from being too tight or too loose; It also includes a support plate 50 hinged to the top of the support rod 41. A cover plate 53 is installed on the support plate 50 via a locking mechanism. Insert rods 52 are symmetrically installed at the bottom of each cover plate 53. The bottom of each insert rod 52 is inserted into a sleeve rod 51. The sleeve rods 51 are all installed on the side wall of the support plate 50. Movable insert rods 544 are inserted into the side wall of each insert rod 52. Second sliders 543 are connected to the inner and outer walls of each movable insert rod 544. The second sliders 543 slide within second slide rails 542. The second slide rails 542 are symmetrically formed within cavities 541, which are located in the middle of a fixed block 54. The fixed block 54 is installed in the middle of the outer wall of the support plate 50. The two sets of movable insert rods 544 are connected by an elastic element 547. Each movable insert 544 has a pusher 545 connected to its inner top. The top of the pusher 545 passes through the movable cavity 546, which is located in the middle of the top of the fixed block 54. A pull handle 531 for pulling is installed in the middle of the top of the cover plate 53. The branches of the tree that need support are placed on the support plate 50 for support. At this time, the pull handle 531 is held to close the cover plate 53 on the support plate 50. After the two sets of pushers 545 are pressed against each other, the two sets of movable inserts 544 are moved inward. At this time, the pusher 545 is released, and under the action of the elastic potential energy of the elastic element 547, the movable insert 544 passes through the outer wall of the sleeve 51 and is inserted into the insert 52, thus completing the insertion and locking work.

[0017] like Figure 1 , Figure 2 and Figure 3 As shown, the device includes a connecting assembly, which includes protrusions 31 on the front and rear outer side walls of the support block 20, a support 32, and a set of hook-shaped frames 33 that are movably arranged along the length of the support 32. The hook-shaped frames 33 hook onto the outer side of the corresponding protrusions 31 and move closer to each other to connect and lock the two support blocks 20 to the outside of the tree.

[0018] The support base 10 is symmetrically arranged on both sides of the tree. The support block 20 is used to contact the tree and distribute the pressure, providing the main support force. The bottom end of the support base 10 is provided with a multi-hole rod 11, which is used to insert into the ground or fixed foundation to achieve stable anchoring of the support base 10.

[0019] The inner wall of the arc-shaped groove is provided with several biomimetic composite materials 21, which can increase the friction with the surface of the tree trunk and prevent slippage; it can also buffer external pressure to avoid damaging the bark, and adapt to the irregular shape of the tree trunk to improve the fit.

[0020] The protrusions 31 are set on the front and rear outer side walls of the support block 20 as locking points of the hook-shaped frame 33. The hook-shaped frame 33 is movably set along the length of the support 32. The hook-shaped frame 33 can hook the outer side of the corresponding protrusions 31 from both sides and lock them by moving closer to each other. It can be quickly fixed by hooking.

[0021] Two sets of protrusions 31 and hook-shaped brackets 33 are provided on the upper and lower sides respectively, and the support 32 is engaged in the gap between the upper and lower protrusions 31.

[0022] A transverse gap is formed between the upper and lower protrusions 31. The support 32 is long and is inserted into the gap between the upper and lower protrusions 31. It is fixed by locking the protrusions 31 with the hook-shaped bracket 33.

[0023] like Figure 3 As shown, Figure 3 The diagram shown is a cross-sectional view of the connecting components in the embodiment.

[0024] The support 32 includes a hollow box 321. A bidirectional threaded rod 322 is rotatably disposed inside the box 321. The upper and lower end faces of the box 321 are provided with strip grooves 324 that communicate with the inner cavity. Threaded sleeves 323 are threadedly fitted on the opposite threaded sections of the bidirectional threaded rod 322. The upper end of the threaded sleeve 323 is fixedly connected to the hook-shaped frame 33 located above by a connecting rod, and the lower end of the threaded sleeve 323 is fixedly connected to the hook-shaped frame 33 located below by a connecting rod.

[0025] The box 321 is hollow and rectangular in shape to accommodate the transmission mechanism. The bidirectional threaded rod 322 is rotatably disposed inside the box 321. It contains two threaded sections with opposite directions of rotation (one left-handed and one right-handed). When it rotates, the threaded sleeves 323 on both sides will move closer to each other or further away from each other. Therefore, when the threaded sleeves 323 move left and right, they drive the upper and lower hook-shaped frames 33 to open and close synchronously.

[0026] Specifically, the front and rear sidewalls of the threaded sleeve 323 are in sliding fit with the corresponding inner walls of the box body 321, so that the threaded sleeve 323 cannot rotate with the bidirectional threaded rod 322, and can only move along the length direction of the box body 321.

[0027] In the locked state, the hook-shaped frame 33 tightly hooks the outer edge of the protrusion 31, and generates a large clamping force, and the hook-shaped frame will not fall off due to the friction in the radial direction.

[0028] One end of the bidirectional threaded rod 322 extends out of the box body 321 and is provided with an operating end 325.

[0029] The operating end 325 is in the form of a handle, a hexagonal head or a knob, etc., and a user can drive the bidirectional threaded rod 322 to rotate by rotating the operating end 325, so as to drive and adjust the hook-shaped frame 33, to realize the locking and loosening actions.

[0030] Working principle: Growth adaptability stage: the bionic composite material 21 provides high friction support (friction angle > 25°) in the initial stage. As the tree grows thicker, the lignin on the surface of the composite material gradually degrades, and the degradation products promote the formation of bark callus; when the degradation depth reaches 2mm, the newly formed bark has completed morphological reconstruction according to the etching path; Mechanical regulation process: the pressure sensor collects the pressure value of the support surface every 24 hours, and when the detection value is > 20kPa for 3 times in a row, the controller starts the driving motor to make the lead screw 412 reverse 90°, and the threaded sleeve block 413 retreats 1mm to release the pressure; when it is a strong wind weather, the hinged structure of the movable support rod 42 allows the branch to swing within a range of 10°, to avoid rigid breakage; Moisture management path: when it rains, water quickly infiltrates to the deep root system through the vertical pore channels (pore diameter 1mm) of the porous insertion rod 11, and at the same time, the lateral micro-pores (pore diameter 0.5mm) form a soil lateral water guide network; in summer high temperature, the soil temperature around the base is reduced by 4-6℃ compared with the traditional metal base.

[0031] The above examples are only used to illustrate the technical solutions of the present application, but not limit it.
