[0035] Further, sealing plugs are plugged on both the water inlet 45 and the water outlet 46.

[0036] Further, a self - locking mechanism is installed on the traveling wheels 3.

[0037] The usage method of the portable monitoring device of the present invention is as follows: Step 1: Push the push rod 23 to move the device to the area to be monitored. Rotate the threaded drill rod 2 to drill the drill bit 7 into the soil to fix the base 4. At this time, the traveling wheels 3 and the universal wheels 6 are not in contact with the ground. Inject water into the cavity 5 of the base 4 through the water inlet 45. After filling, plug the water inlet 45 with a sealing plug to increase the weight of the base 4, which is used to improve the overall stability of the device. Then, hang the lower hook 19 into the lower hanging ring 10, and hang the upper hook 12 into the upper hanging ring 18 to make the steel wire rope 11 taut. Utilize the tension of the four groups of anti - tipping mechanisms composed of the counterweight 9, the lower hanging ring 10, the lower hook 19, the steel wire rope 11, the upper hook 12 and the upper hanging ring 18, as well as the gravity of the counterweight 9 and the base 4, so that the accommodation box 16 will not tilt; Step 2: Select one of the monitors 30 and move it onto the placement table 39 according to the content to be monitored. Specifically, the initial position of the placement table 39 is that its upper surface is on the same horizontal line as the upper surface of the annular fixing seat 29. Turn on the stepper motor 37 to rotate the placement table 39 until the third electric push rod 47 is perpendicular to the first electric push rod 14 on the side where the monitor 30 is located. Rotate the screw rod 15 above the monitor 30 to move the pressure plate 35 away from the monitor 30. Turn on the first electric push rod 14 on the side where the monitor 30 is located. Extend its telescopic rod to push the monitor 30 onto the placement table 39. Extend the telescopic rod of the third electric push rod 47 to make the clamping block 44 abut against the monitor 30. Use the clamping block 44 to clamp and fix the monitor 30. Turn on the stepper motor 37 again to rotate the placement table 39 until the slots 40 are located on the left and right sides of its upper surface. Step 3: The telescopic rod of the second electric push rod 21 extends to raise the placement platform 39 and the monitor 30. During the rising process, the insertion rod 41 on the lower surface of the cover plate 32 is inserted into the slot 40 on the upper surface of the placement platform 39. The placement platform 39 continues to rise, driving the cover plate 32 to rise. When it rises to the required monitoring height of the monitor 30, the stepper motor 37 is used to drive the placement platform 39 and the monitor 30 to rotate, so that the monitor 30 can perform 360-degree all-round monitoring, improving the monitoring accuracy. During the monitoring process, the cover plate 32 can shield and protect the monitor 30. Step 4: After the monitor 30 completes monitoring, the telescopic rod of the second electric push rod 21 shortens to reset the placement table 39, and the placement table 39 is rotated by the stepping motor 37 until the third electric push rod 47 is perpendicular to the first electric push rod 14 corresponding to the monitor 30. The telescopic rod of the first electric push rod 14 corresponding to the monitor 30 is extended until the electromagnet 48 fixed at its free end contacts the iron block 49 on the side wall of the monitor 30. The electromagnet 48 is energized to attract the iron block 49, and the telescopic rod of the first electric push rod 14 contracts to reset the monitor 30. After resetting, the electromagnet 48 is de-energized, and the screw 15 above it is rotated to lower the pressure plate 35 to contact the monitor 30 to fix it. Step 5: When a new monitor 30 needs to be replaced according to the monitoring content, repeat the above step 2, and then repeat the above steps 3 and 4 in sequence, so that the device can use different monitors 30 to monitor different items of mine geology, which is highly practical.
