A fixing snap-fit ​​block is snapped into the fixed snap-fit ​​hole. An arc-shaped block is installed at one end of the fixing snap-fit ​​block.

[0018] According to the above technical solution, the top connecting rod extends out of the top of the inner tube;

[0019] The rotating solenoid passes through the threaded hole at the top of the outer tube and is screwed into the threaded hole at the top of the top connecting rod.

[0020] According to the above technical solution, the snap-fit ​​circular block is snapped into the inside of the snap-fit ​​circular hole;

[0028] The input terminals of the tree monitoring camera, the first drive motor, the second drive motor, and the electric push rod are electrically connected to the output terminal of the battery.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0030] 1. By setting up a rotating solenoid, support rod, fixed plate, mounting rod, internal gear ring, semi-circular gear rod, first drive motor, first drive gear, second drive motor, and second drive gear, the first drive motor drives the first drive gear to rotate, which in turn drives the internal gear ring to rotate. The second drive motor drives the second drive gear to rotate, which in turn drives the semi-circular gear rod to rotate, thus rotating the tree monitoring camera at the top of the mounting rod to a suitable viewing angle. This ensures that all tree monitoring cameras are placed in a suitable position, resulting in a wider monitoring range and better monitoring effect. By rotating the support rod, the rotating solenoid can be unscrewed from the top of the top connecting rod, allowing the tree monitoring camera to be removed for inspection and maintenance.

[0031] 2. By setting up an electric push rod, a snap-fit ​​plate, a movable plate, an inner tube, an outer tube, snap-fit ​​round holes, snap-fit ​​round blocks, fixed snap-fit ​​holes, fixed snap-fit ​​blocks, arc-shaped blocks, and a converging ring, the electric push rod pushes the top connecting rod and the outer tube, causing the support rod and tree monitoring camera to move upward. The tree monitoring camera is adjusted to a suitable monitoring height according to the tree height and the position of the monitoring device. As the tree grows, the height of the tree monitoring camera is continuously adjusted, resulting in more accurate monitoring data. During maintenance, moving the converging ring upward releases the constraint on the arc-shaped block, pulling out the arc-shaped block and the fixed snap-fit ​​block releases the constraint on the snap-fit ​​round block, and moving the movable plate, inner tube, and outer tube upward. Finally, the outer tube and inner tube are removed, allowing for maintenance of the top connecting rod and the electric push rod.

[0032] 3. By setting up a placement slot, placement plate, heat dissipation slot, battery, angled slot, mounting slot, positioning slot, L-shaped lever, limit slot, air outlet, angled baffle, angled rod, and connecting hole, the battery is inserted into the top of the placement plate. The placement plate and battery are then placed inside the placement slot. The L-shaped lever is inserted from the mounting slot into the positioning slot to fix the pull-out block to the movable base. The L-shaped lever is then rotated to engage inside the limit slot, completing the battery installation and powering the monitoring device. The battery is ventilated and cooled through the air outlet and connecting hole to ensure battery life and prevent damage from prolonged high temperatures. The outer angled baffle and angled rod can block external dust and rainwater, and the battery is easy to install and remove, meeting the power supply needs of tree monitoring cameras.

[0033] In summary, two drive motors rotate the drive gears, which in turn drive the internal gear ring and the semi-circular gear rod to rotate. This causes the mounting rod and the tree monitoring camera on top of it to rotate to a suitable monitoring angle. An electric push rod then pushes the outer tube upwards to meet the monitoring needs of trees at different heights. Automatic adjustment saves labor costs and improves monitoring efficiency. The bottom battery powers the tree monitoring camera, and ventilation holes and connecting holes provide heat dissipation. Battery replacement and maintenance are convenient, making the monitoring device easy to use, flexible, and highly efficient. Attached Figure Description

[0057] The mobile base 1 has a placement slot 601 at its bottom, and a placement plate 602 is snapped into the inner side of the placement slot 601.

The top of the movable base 1 is provided with a connecting hole 614.

[0059] The working principle and usage process of this invention are as follows: First, before using the monitoring device to monitor tree growth, insert the fully charged battery 604 into the top of the placement plate 602, then insert the battery 604 into the inclined slot 606 to secure the placement plate 602 and the battery 604 inside the placement slot 601. Then, insert the L-shaped lever 609 from the mounting slot 607 into the positioning hole 608 to fix the pull-out block 605 to the movable base 1. Then, rotate the L-shaped lever 609 so that its top is engaged inside the limiting slot 610 to complete the installation of the battery 604 and power the monitoring device. During use, the battery 604 is ventilated and cooled through the air outlet 611 and the connecting hole 614 to ensure the use of the battery 604 and prevent the battery 604 from being damaged by high temperature for a long time. The outer inclined baffle 612 and the inclined side rod 613 can block external dust and rainwater.

[0060] Then move the monitoring device to the location that needs to be monitored, and push the top connecting rod 302 and the outer tube 307 through the electric push rod 301, thereby pushing the top support rod 403 and the tree monitoring camera 5 to move upward. Adjust the tree monitoring camera 5 to a suitable monitoring height according to the height of the tree and the distance between the monitoring device and the tree. As the tree grows, the height of the tree monitoring camera 5 can be continuously adjusted to make the monitoring data more accurate.

[0061] After the height adjustment is completed, the first drive motor 414 drives the first drive gear 415 to rotate, which drives the internal gear ring 411 to rotate, thereby rotating the tree monitoring camera 5 on the top of the mounting rod 406 on one side to a suitable viewing position. Then, the second drive motor 416 drives the second drive gear 417 to rotate the semi-circular gear rod 412, thereby rotating the tree monitoring camera 5 on the top of the mounting rod 406 on the other side to a suitable viewing position. This ensures that the tree monitoring cameras 5 are all placed in suitable positions, resulting in a wider monitoring range and better monitoring effect.

[0062] When inspecting the monitoring device, first use the electric push rod 301 to move the outer tube 307 and support rod 403 downwards. Rotate the support rod 403 to unscrew the rotating screw tube 401 from the top of the top connecting rod 302, and the tree monitoring camera 5 at the top can be removed for inspection. Then move the agglomerated ring 314 upwards to release the position restriction on the arc block 313. Pull the arc block 313 and the fixing block 312 outwards to release the restriction on the locking block 310. Then move the moving plate 305, inner tube 306 and outer tube 307 upwards. Finally, remove the outer tube 307 and inner tube 306. The top connecting rod 302 and electric push rod 301 can be inspected. Disassembly is simple and convenient and does not require tools.
