Description

Technical Field

When the inspection vehicle travels in the field ditches, it will not damage the crops in the farmland or stir the soil, thereby avoiding the influence of gas release in the soil on the monitoring results.

[0041] 2. Through the design of the large wheels and the small wheels, when the inspection vehicle is not traveling in the field ditch, the large wheels are in direct contact with the ground, and there is no need to adjust the wheelbase, thereby improving the moving speed of the inspection vehicle when it is not traveling in the farmland.

[0042] 3. The present application adopts the design of the bidirectional screw of the screw transmission mechanism and the design of the grabbing components, the first cantilever and the second cantilever on the left and right sides of the inspection vehicle, which not only makes it unnecessary for the inspection vehicle to set up a separate counterweight block to maintain balance during work, but also greatly improves the working efficiency of the inspection vehicle.

[0043] 4. Through the overall design of the walking mechanism, the screw transmission mechanism and the placement mechanism, the present application can quickly move the monitoring room and the square soil ring at a position to the next position after the monitoring time of the monitoring system at a position is reached. Compared with the traditional method of installing a monitoring system for each monitoring position, the inspection method of the present application uses much fewer monitoring systems.
