[0034] The implementation principle of the embodiment of the present application is as follows: first, the main frame 1 is fixedly placed at the position required for testing, and the servo motor 7 drives the reducer 8 to decelerate and then drives the lead screw 4 to rotate, and the rotation of the lead screw 4 drives the threaded moving block 6 to perform lifting and lowering movements, and the movement of the threaded moving block 6 drives the drill rod 10 to move downward, and the movement of the drill rod 10 drives the probe 11 to move downward in translation, and the probe 11 slowly enters the soil layer after passing through the through groove 12, and the cone tip resistance sensor 13 and the side wall friction sensor 14 respectively measure the current rock and soil cone tip resistance and side wall friction, and the temperature sensor 15 monitors the ambient temperature, and synchronous testing is performed through multiple groups of probes 11 to achieve multi-point synchronous testing and improve test efficiency, and the microprocessor 16 is responsible for data acquisition and processing, power management Unit 19 provides stable power supply, communication interface 17 supports wired and wireless transmission, which is convenient for data uploading, data storage module 21 is used to save raw data, and data analysis software 22 is used to display and analyze test results in real time. During the test, the cone tip resistance sensor 13 and the side wall friction sensor 14 respectively measure the cone tip resistance and side wall friction of the current rock and soil, and the temperature sensor 15 monitors the ambient temperature and transmits the signal to the microprocessor 16. The control system 18 in the microprocessor 16 collects sensor data in real time and uploads it to the data processing unit 20 through the communication interface 17. The data processing unit 20 stores and analyzes the raw data, generates a test report, and transmits the signal to the display 23, so that the test data can be displayed. To facilitate staff to observe and record, the connection frame 25 and the electric telescopic rod 27 are connected by the rotating shaft 26 so that the electric telescopic rod 27 can rotate along the rotating shaft 26 to adjust the angle. The electric telescopic rod 27 plays a supporting role and has a locking structure. In the case of power failure, the current state can be maintained without being telescopically moved. The electric telescopic rod 27 can be telescopically supported and adjusted to ensure that the device remains stable on uneven ground. The support plate 29 connected by the universal joint 28 plays a stabilizing support role. The support plate 29 of the electric telescopic rod 27 can keep close to the ground at any angle, thereby improving the stability of the device. The micro motor 33 drives the worm 32 to rotate, and the rotation of the worm 32 drives the worm wheel 31 to rotate. The worm gear 31 rotates, the worm gear 31 rotates to drive the rotating shaft 26 to rotate synchronously, and the rotating shaft 26 rotates to drive the electric telescopic rod 27 to adjust the support angle, so as to stabilize the device. At the same time, the electric telescopic rod 27 can follow the rotation of the rotating shaft 26 to retract to the bottom end of the main frame 1 for storage, so as to facilitate storage and transportation when not in use. The current level of the main frame 1 can be detected by the level meter 34, so that the signal is transmitted to the microprocessor 16 through the communication interface 17. The microprocessor 16 controls the electric telescopic rod 27 and the micro motor 33 to adjust the level of the device, thereby improving the stability of the device. At the same time, when the support mechanism 24 needs to be stored, the auxiliary roller 36 can be pushed by the electric push rod 35 to contact the ground.The electric telescopic rod 27 and the support plate 29 are lifted off the ground, and the electric telescopic rod 27 is driven by the micro motor 33 to be stored, thereby completing the storage of the support mechanism 24. After storage, the electric push rod 35 is retracted to the original position, and the device is assisted to move by the auxiliary roller 36, thereby improving the mobility of the device. The second photovoltaic panel 43 and the first photovoltaic panel 38 can both perform photovoltaic power generation corresponding to each other. By pulling the second photovoltaic panel 43, the second photovoltaic panel 43 and the guide rod 40 can slide synchronously, so that the second photovoltaic panel 43 moves to the first photovoltaic panel 38. The two sides of the edge of the No. 1 photovoltaic panel 38 are arranged to increase the light receiving area. The No. 2 photovoltaic panel 43 and the No. 1 photovoltaic panel 38 are deployed in coordination to increase their power generation. At the same time, the No. 2 photovoltaic panel 43 can be deployed to shield the main frame 1 to prevent direct sunlight from shining on the main frame 1, thereby causing temperature rise and affecting the processing efficiency of the microprocessor 16. The mobile power supply 9 can store the electricity generated by the No. 2 photovoltaic panel 43 and the No. 1 photovoltaic panel 38 through the inverter to facilitate the subsequent power supply of the device, thereby improving the endurance of the device and making it usable even without an external power supply.
