The spike 604 slides out of the oblique slot 606 under the action of the spring two 605, and is in sliding abutment with the inner wall of the conical fixed cylinder 601, so as to firmly hold the slope soil body and prevent the device from loosening or sliding out. In addition, the auxiliary anti-off assembly 9 is arranged in the vertical rod 2, and the auxiliary anti-off assembly 9 comprises two auxiliary fixing plates 901, one end of which is rotatably connected in the inner groove 902 of the vertical rod 2, and the other end is automatically inserted into the deep slope under the action of the spring one 903, so as to significantly improve the stability of the device.

[0035] Referring to Figure 1 - Figure 2, the device is provided with an inclination detection assembly 7 at the front side of the middle part of the vertical rod 2, which is used for real-time monitoring of the slope inclination change. The inclination detection assembly 7 includes an angle scale 701 and a pointer 702, the angle scale 701 is semicircular and provided with scales, and the pointer 702 is rotationally connected with the angle scale 701 through a rotating shaft 703, which directly displays the inclination change. At the same time, an inclination sensor 11 is also installed at the top of the horizontal rod 1, which is used for high-precision monitoring of the slope change and transmitting data to the control box 8 installed at the rear side of the vertical rod 2. The control box (8) is the core unit of the whole monitoring device, which contains multiple key elements inside, such as controller, wireless transmission module, analog signal receiver, data storage module. Among them, the controller selects a programmable logic controller (PLC), such as an STM32 microcontroller based on an embedded system, which is responsible for realizing data acquisition, processing, storage and control logic execution. The inclination sensor 11 is connected with the controller through I2C or UART interface, which collects the slope inclination angle data in real time and transmits it to the controller for processing.

The device is firmly inserted into the slope soil through the fixed assembly 6 at both ends of the horizontal rod 1 by using the conical fixed cylinder 601, the control rod 602, the spike 604 and the spring two 605. In order to prevent loosening, the auxiliary anti-loosening assembly 9 of the vertical rod 2 automatically penetrates into the soil when loosening by using the auxiliary fixed plate 901 and the spring one 903. The inclination detection relies on the mechanical type inclination detection assembly 7 and the electronic inclination sensor 11 installed on the vertical rod 2 to record the slope change data, and the control box 8 sends out an alarm through the alarm 10 when the inclination is abnormal. The osmometer 5 in the bottom protection sleeve 4 is buried in the deep part of the slope, detects the seepage pressure, and transmits the data to the monitoring center through the wireless module, so as to provide real-time data support for stability evaluation.
