1. An apparatus for monitoring deformation of a reservoir landslide under water of a reservoir, comprising at least one buoy-type monitor, wherein the buoy-type monitor comprises a floating shell, a data monitoring system, and an anchor securing the floating shell from drifting around, the floating shell and the data monitoring system and the anchor are fixedly connected, the floating shell is hollowed-out for floating on a water surface, and the data monitoring system comprises a pull cord, a displacement compensation mechanism, and a global positioning system (GPS) sensor, a water temperature sensor, a gravity wave gauge, an encoder-type displacement meter, and an integrated circuit that are secured in the floating shell;
the GPS sensor is configured to transmit and receive a GPS signal to obtain a real-time position of the floating shell, the water temperature sensor is located below the water surface to monitor a change of water temperature in real time and obtain a water temperature-time relationship, and the gravity wave gauge is operable to obtain, after the floating shell floats with a wave, wave height information calculated by a built-in accelerometer, to obtain a wave height-time relationship;
an upper end of the pull cord is securely connected to the floating shell via the displacement compensation mechanism, and a lower end of the pull cord is securely connected to the anchor, the displacement compensation mechanism is configured to compensate for a displacement after the floating shell floats with the wave, so that the pull cord is constantly kept in a tensioned state, and the encoder-type displacement meter is located below the GPS sensor, and configured to measure a real-time distance between the encoder-type displacement meter and the anchor; and
the integrated circuit is electrically connected to the GPS sensor, the water temperature sensor, the gravity wave gauge, and the encoder-type displacement meter, and configured to collect, process, and transmit monitoring data.
