The utility model is inserted into the slope body of the slope through the fixed column, and the steel wire is connected to the tension sensor through the metal seat and the electromagnet block. When the slope body of the slope has a downward trend, it will pull the fixed column.

[0026] In addition, through the cooperation of the balancing gear 21 and the synchronous rack 22 in the slope extension 2, when the slope soil layer slides, it can cooperate to pull the synchronous rack 22 to slide in the opposite direction, and then drive the balancing gear 21, the trigger gear 23 and the transmission gear 24 to rotate, thereby triggering the displacement sensor 25.

[0029] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0030] The implementation principle of a slope stability monitoring device in the embodiment of the present application is:

[0031] When in use, first place the top machine 1 on the top of the slope, and ensure that the end of the top machine 1 and the docking ear plate 11 are close to the highest point of the slope, and then the large anchor rod 12 is inserted into the ground through the retaining edge for fixing, and the transfer platform 3 on the docking ear plate 11 is turned over, so that the transfer platform 3 can be freely placed on the slope, and multiple slope extensions 2 are connected through the connecting rod 210, and the topmost connecting rod 210 is connected to the transfer platform 3, so that multiple slope extensions 2 are laid along the slope, and a suitable number of slope extensions 2 are installed according to the length of the slope, and finally, the small anchor rod 211 is inserted into the inside of the slope through the retaining edge to fix the slope extension 2 and complete the installation;

[0032] When the soil layer of the slope slides, the slope extension 2 at the corresponding position will be triggered to slide down, and the tension will be transmitted to the transfer platform 3. The stress of the slope soil layer can be monitored through the tension sensor 31 on the transfer platform 3. When the stress exceeds the critical value, the wireless alarm module 13 on the top machine 1 can be used to sound an alarm. In addition, the two synchronous gears in the slope extension 2 will slide in the opposite direction, which will drive the balance gear 21 and the trigger gear 23 to rotate. The trigger gear 23 can also drive the transmission gear 24 to rotate, thereby triggering the displacement sensor 25 to accurately monitor the sliding of the soil layer.
