The invention discloses an underground
television system for exploring a deep
karst cave of a bridge
pile foundation, the underground
television system comprises a hoisting mechanism and an underground
camera module, the hoisting mechanism drives the underground
camera module to go in and out of the deep position of the
pile foundation, and the underground
camera module comprises a camera module, a
gyroscope module, a power supply module, a
signal transmission module and a vertical cage type frame; the camera module and the
gyroscope module are arranged in the cage type frame in a spaced mode in the vertical direction, the
gyroscope module is used for keeping the posture of the underground camera module stable, the camera module comprises a camera, a searchlighting unit and a camera
servo rotary table, the camera is rotatably installed in the cage type frame through the camera
servo rotary table, and the power supply module supplies power to the underground camera module. The
signal transmission module transmits imaging information of the camera module to the outside. By arranging the underground camera module with a high-brightness
light source, controllable posture and clear imaging, the development and communication conditions of the deep
karst cave of the
pile foundation can be stably and effectively explored, meanwhile, personnel do not need to go down to a well for investigation, and safety is guaranteed.
