The invention discloses a self-adjusting sand intrusion-prevention radar detecting trolley. The structure of the self-adjusting sand intrusion-prevention radar detecting trolley comprises wheels, a main body, a balancer, a radar detection lower connector, and a sand-proof processing device. With the self-adjusting sand intrusion-prevention radar detecting trolley of the invention adopted, after sand enters joint gaps, the temperature of the interior of the trolley rises, a heat conduction bag and a memory alloy sheet expand thermally and deform after the temperature rises, so that a squeezingplate is pushed upward to squeeze out water from water absorption sponge; the sand is discharged to the lower part of the device; and due to the infiltration capacity of the water, the sand is completely wrapped by the water, so that the specific heat capacity of the sand is increased, and the temperature of the sand will not rise too fast. In the high-temperature environment of a desert, water inside the trolley is evaporated; a leak-proof condensing device inside the trolley automatically collects water vapor; the sand enables a thermal actuator to act in the temperature rise process, so that a sand collecting plate and a fixing plate are pushed open, and the sand inside is discharged; and therefore, too fast temperature rise inside the trolley due to the accumulation of too much sand can be avoided, and the false alarms of laser radar detection can be prevented.
