Title:
DEVICE FOR MEASURING THREE-DIMENSIONAL INFORMATION OF UNDERGROUND SPACE AND DETECTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/047391
Kind Code:
A1
Abstract:
A device for measuring three-dimensional information of an underground space and a detection method therefor, the measuring device comprising a sensor system, a power system, a housing protection system and a conduction system; the housing protection system comprises a constituent part of a sealed upper portion metal housing (3-1) and lower portion metal housing (3-9); the power system comprises a motor (2-1), a signal transmitter (2-2), a magnetometer (2-3), a gyroscope (2-4) and a circuit board (2-5); the sensor system comprises an ultrasonic sensor (1-1), a temperature sensor (1-2) and a video sensor (1-3); and the conduction system comprises a metal contact pin (4-1), a gear (4-3) and an upper end cap (4-4) wherein an upper portion is connected to a lifting cable, the metal contact pin (4-1) being provided at a top end of the upper portion metal housing (3-1). The measuring device may monitor the three-dimensional shape of an underground cavern at high temperatures and under high pressure, the acquired cavity shape information being significant to the evaluation of the stability of an underground structure. The detection method for the measuring device is simple to operate, and may effectively detect three-dimensional space information of an underground cavern at high temperatures and under high pressure.
