Device for detecting cracks of underwater building

Abstract

The invention relates to the field of detection of underwater buildings, in particular to a device for detecting cracks of an underwater building. A lifting assembly is arranged on a fixed base fixedly connected on a ship body, a connecting column is fixedly connected on the bottom of a movable plate in transmission connection on the lifting assembly, and a mounting cavity is arranged on a rectangular base fixedly connected to the bottom end of the connecting column; a first motor is fixedly connected on the top inner wall of a ring-shaped slot formed in the top inner wall of the mounting cavity, a rotary disc is fixedly connected on the output shaft of the motor, an electric push rod is fixedly connected on the bottom of the rotary disc, a connecting plate is fixedly connected on the output shaft of the electric push rod, and a fixed plate is fixedly connected on the bottom of the connecting plate; and the bottom of the fixed plate extends to a position below the bottom of a rectangular base; detectors are fixedly connected at the two sides of the fixed plate; and an anti-impact assembly is arranged on the rectangular base. The device solves the problems that a conventional detector has a detection dead corner, is liable to have a detection leakage phenomenon, and is easily damaged as a result of impact of water flow.

Description

technical field [0001] The invention relates to the field of detection of underwater buildings, in particular to a crack detection device for underwater buildings. Background technique [0002] Most of the important structures in underwater buildings are composed of concrete components. In the long-term use process, due to the intrusion of external factors such as wind and waves, corrosion, hydraulic erosion and temperature stress, the buildings will crack, which requires timely repair. Detection of underwater structures. [0003] The existing detection of underwater buildings generally uses crack detectors for detection, but the traditional crack detectors have detection dead ends, which are prone to missed inspections, and the detectors are vulnerable to the impact of water flow, causing damage, so we propose a A device for detecting cracks in underwater buildings is used to solve the above-mentioned problems. Contents of the invention [0004] In view of this, the pre...
