The working principle is as follows:
when the whole vehicle runs for the first time, the sail mechanism is lifted by the hydraulic cylinder 15.1, so that the windward effect of the largest area is realized, and the starting of the vehicle is facilitated. And then, the wind speed and the wind direction under a specific environment are collected through a wind speed and wind direction sensor 11, corresponding data are transmitted to a controller 12, and after the controller 12 analyzes and processes the data, the sail assembly is controlled to change different modes according to different data information. When the wind speed and the vehicle speed are within a certain range, the sail mechanism is not required to be adjusted. When the wind speed is not in the set interval, the control circuit is divided into the following conditions: 1. when the wind speed is not large, the sail motors 17 can be controlled to rotate, so that the windward angles of the three sails reach 90 degrees, the windward areas reach the maximum, and the vehicle speed can be increased in a mode of increasing the areas. 2. When the wind speed is too high, there are two control methods, the first is to control the second sail unit to reduce the vehicle speed. The servo motor 20 is controlled to rotate to drive the rotating connecting piece 19 to rotate, so that the second sail unit is controlled to rotate, a certain number of small sails are controlled according to a certain sequence, the second sail unit rotates to an angle parallel to the wind direction, the driving force of the scientific investigation vehicle can only be generated by the remaining sail units vertical to the wind direction, and the vehicle speed is reduced by reducing the area of the sails of the scientific investigation vehicle. The second method is to control the angle of the large sail to the wind to reduce the speed of the vehicle. The driving mast 6 and the driving sail body 7 are driven to rotate by controlling the sail motor 17, and the driving sail body 7 controls the driven sail 4 to rotate by the sliding groove 9.3 connecting rod mechanism, so that synchronous rotation of three large sails is realized, an included angle between the whole sail and the wind direction is reduced, and the speed of the vehicle is reduced. 3. When the wind speed exceeds the set wind speed peak value, the current wind speed is over high, and the damage of the wind sail and the instability of the scientific investigation vehicle can be caused. At this time, the controller 12 controls the gas-liquid pressure rod 15.2 to contract, drives the sail mechanism to integrally pitch through the connecting rod, and is attached to the frame 3, so that the windward area of the sail is zero, the scientific investigation vehicle keeps a static state, and when the wind speed and the wind direction detection sensor detect that the wind speed is reduced to a reasonable value, the three sail mechanisms are lifted, and the scientific investigation vehicle continues to advance.
