Abstract

The invention provides a self-adjusting type permafrost protecting device. The protecting device comprises a support and a fiber plate, wherein a solar cell panel and a cover plate are mounted on the support; a driving motor controlled by an automation controller is mounted on the cover plate; two sets of telescopic guide rails are arranged on each of the upper surface and the lower surface of the cover plate; the driving motor drives the four sets of telescopic guide rails to extend or retract simultaneously; sun shielding plates are arranged on the telescopic guide rails; and the automation controller is used for setting an upper limit valve and a lower limit value of the temperature in advance, detecting the environment temperature, comparing a detected environment temperature value with the preset upper limit valve and the preset lower limit value of the temperature and controlling the driving motor according to the detected environment temperature so as to enable the telescopic guide rails to extend or retract. By the aid of the protecting device, the sun shielding plates can be extended or retracted according to the environment temperature, so that the heat transmitted to side slopes can be reduced, and excessive evaporation of side slope moisture can be prevented; side slope wind erosion can be prevented; and heat and moisture replenishment required by normal growth of side slope plants can be guaranteed. In addition, the protecting device can be recycled.
