A hollow anchor rod 15 is inserted through the middle of the base plate 1, and the soil moisture sensor 14 is located at the bottom of the hollow anchor rod 15. The wireless transmission module is a LoRa wireless transmission module 16. A planar thrust ball bearing 17 is provided between the outer shell 4 and the main pipe 2. The upper ring of the planar thrust ball bearing 17 abuts against the outer shell 4, and the lower ring abuts against the upper end of the main pipe 2. The outer shell 4 has a hollow column 18 inserted into the main pipe 2, and the outer shell 4... A through hole 19 is provided, communicating with the hollow column 18 and allowing the first wire 9 to pass through. A first gear 20 is detachably mounted on the lower end of the hollow column 18. A support 21 is provided inside the main pipe 2, and a motor 22 is detachably mounted on the support 21. A second gear 23 that meshes with the first gear 20 is sleeved on the shaft of the motor 22. The motor 22 is powered by a power supply 6 and is connected to a PLC 7 via a second wire 24. The PLC 7 controls the motor 22 according to a preset program. A sleeve 25 is provided at the lower end of the outer casing 4, which is fitted onto the main pipe 2. The inner ring of the sleeve 25 has multiple sealing rings 26 from top to bottom, and the sealing rings 26 are coated with lubricating oil.

[0024] The sleeve 25, sealing ring 26 and lubricating oil are designed to prevent longitudinal displacement of the housing 4 during rotation, making the rotation more precise.

[0025] The solar panel 28 is designed to convert solar energy into electrical energy to charge the power supply 6. On the other hand, its area is larger than the upper surface area of the outer casing 4, which can provide a certain degree of protection for the outer casing 4, slow down the aging process of the outer casing 4 and the small laser projector 5, and make the outer casing 4 and the small laser projector 5 have a longer service life.
[0026] The first assembly port 31 and the first lockable door plate 32 facilitate the assembly of the support 21, motor 22, first gear 20 and second gear 23, and also facilitate subsequent maintenance work.
[0027] The speaker 34 can work with the small laser projector 5 to provide sound escape guidance. In addition, when the main pipe 2 is bent or damaged due to geological disasters, the speaker 34 can also emit sound notifications of safe locations or safe directions, so that the victims know the approximate escape direction and can then escape to a safe location. The second assembly port and the second lockable door panel 35 facilitate the assembly of the frame 33, power supply 6, PLC 7, tilt sensor 13, sensing module and other structures, and also facilitate later maintenance work.
