According to the modal-switchable cross-medium environment detection platform, an air pump is used for inflating and deflating the floating air bag, so that the volume of the floating air bag is reduced and the buoyancy is greater than the gravity in the diving process, and diving is realized; the counterweight adjusting mechanism is used for releasing a counterweight after data acquisition is completed, so that the gravity is greater than the buoyancy, and floating is realized; the sensor mechanism mounting box is convenient to mount by utilizing the side edge clamping mechanism, and the sensor mechanism mounting box carrying different sensors is convenient to replace; and the landing support mechanism is linked with the counterweight adjusting mechanism, so that the landing support mechanism does not influence each sensor before data acquisition is completed, and meanwhile, the instrument is prevented from being collided during recovery and landing.
