Specific embodiments

[0023] The following describes the present utility model in further detail with reference to specific embodiments. The illustrative embodiments and descriptions of the present utility model are used to explain the present utility model, but not to limit the present utility model.

[0024] Embodiment: As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 shown, a soil moisture sensor for detecting the soil matrix temperature of a highway rock slope.

[0025] The first embodiment of the present utility model, referring to Figure 1 , a soil moisture sensor for detecting the soil matrix temperature of a highway rock slope, comprising a frame 1. The frame 1 is a hollow sheet metal housing structure, which provides an installation place for other components. A fixed arm 2 is provided at the upper part of the frame 1. The outer end of the fixed arm 2 is rotatably provided with a swing arm 3 through a rotating rod. A control terminal 8 and a probe 801 are provided on the swing arm 3. The probe 801 penetrates into the soil to detect the temperature and moisture inside the soil, and transmits the detected data to the control terminal 8. Preferably, as Figure 2 , Figure 3 , Figure 4 and Figure 5As shown in the figure, a lead screw 5 is slidably arranged at the lower end of the swing arm 3. The probe 801 is arranged at the lower end head of the lead screw 5. A sliding sleeve 301 is arranged at the lower end of the swing arm 3. The lead screw 5 is slidably arranged inside the sliding sleeve 301. The anti-rotation bar 302 arranged inside the sliding sleeve 301 is in sliding cooperation with the guiding groove 501 opened on the lead screw 5. The anti-rotation bar 302 and the guiding groove 501 cooperate with each other to prevent the lead screw 5 from rotating inside the sliding sleeve 301. A first gear 4 is rotatably arranged at the lower part of the swing arm 3. The lead screw 5 is in threaded connection with the threaded hole opened in the middle of the first gear 4. A first motor 7 is fixedly arranged at the lower part of the swing arm 3. A second gear 6 is arranged at the lower end of the output shaft of the first motor 7. The first gear 4 is in meshing connection with the second gear 6.

[0026] When performing the detection of the soil on the highway slope, the second gear 6 is driven to rotate by the first motor 7. The second gear 6 drives the first gear 4 to rotate. Since the lead screw 5 is in threaded connection with the threaded hole in the middle of the first gear 4 and the lead screw 5 will not rotate along with the first gear 4, therefore, while the first gear 4 rotates, the lead screw 5 drives the probe 801 to slide along the sliding sleeve 301, so that the probe 801 is inserted into the interior of the soil on the highway slope, and then the soil is detected.

[0027] For the second embodiment of the present utility model, refer to Figure 3 , Figure 4 and Figure 5 As shown in the figure, a profiling groove 101 matching with the highway guardrail is arranged inside the frame 1. The frame 1 is slidably arranged outside the highway guardrail through the profiling groove 101. A small wheel 13 is rotatably arranged inside the installation groove 102 opened in the middle of the frame 1 through a rotating shaft 14. The frame 1 is provided with a power device for driving the small wheel 13 to rotate. Preferably, the power device includes a third gear 15, a fourth gear 16 and a second motor 17. The third gear 15 is arranged at the top of the rotating shaft 14. The second motor 17 is arranged inside the square opening opened at the upper part of the frame 1. The fourth gear 16 is arranged at the lower end of the output shaft of the second motor 17. The third gear 15 is in meshing connection with the fourth gear 16. Preferably, a large wheel 12 is rotatably arranged at the lower end of the swing arm 3. Preferably, a fixing frame 19 is obliquely arranged at the outer end of the fixing arm 2. A spring 11 is arranged between the fixing frame 19 and the swing arm 3.

[0028] When conducting soil detection on highway slopes, the frame 1 is clamped outside the highway guardrail through the profiling groove 101. Driven by the second motor 17, the fourth gear 16 drives the third gear 15 to rotate, and then the rotating shaft 14 drives the small wheel 13 to rotate. When the small wheel 13 rotates, it rolls along the highway guardrail, thereby driving the frame 1 and the upper components to move along the highway guardrail. The large wheel 12 contacts the highway slope and rolls along the highway slope as the frame 1 moves. The elastic force of the spring 11 can press down the swing arm 3 to prevent the large wheel 12 from bouncing off the highway slope when the device moves, improving the stability of the device's movement. In this way, the device can automatically move along the highway guardrail, facilitating soil detection operations at different ends of the highway slope.

[0029] To enable the device to work automatically for a long time, as Figure 1 and Figure 3 shown in the third embodiment of the present utility model, a solar panel 10 is provided on the outer side of the fixed frame 19, and a storage battery 18 is provided in the notch opened on the lower surface of the swing arm 3. The output end of the solar panel 10 is electrically connected to the input end of the storage battery 18 through an inverter. The input ends of the first motor 7, the second motor 17, and the control terminal 8 are all electrically connected to the output end of the storage battery 18. Preferably, a signal transmitter 9 is further included. The signal transmitter 9 is provided at the lower end of the swing arm 3, and the control terminal 8 is bidirectionally electrically connected to the signal transmitter 9. The solar panel 10 can convert solar energy into electrical energy, and then store the electrical energy in the storage battery 18 through the conversion of the inverter for the electrical components inside the device to work. At the same time, the signal transmitter 9 can receive and transmit signals, and the detection personnel can control the device through an external terminal, thereby realizing remote control of the detection operation and greatly reducing the work burden of the detection personnel.
