Railway bridge underwater pier disease detection device

Abstract

The invention relates to the field of railway bridge underwater pier disease inspection, in particular to a railway bridge underwater pier disease detection device using an underwater robot to carry acoustic, optical and mechanical equipment and water surface control processing equipment, and surface defect detection of a bridge underwater structure is achieved. The technical problem of the invention is to provide a railway bridge underwater pier disease detection device which comprises a workboat, an underwater robot, a mechanical scanning sonar, a multi-beam sonar and the like. The workboat floats on a water layer, the bridge pier is located in the water layer, the workboat is connected with an underwater robot through a circuit, the underwater robot is located in the water layer, a mechanical scanning sonar is arranged on the underwater robot, and a multi-beam sonar is arranged on the underwater robot. The multi-beam sonar is arranged, the multi-beam sonar is used for finely scanning the surface of the underwater bridge pier, surface diseases of the underwater bridge pier are found by observing real-time sonar images, the condition of the underwater bridge pier can be mastered in time, related dangerous cases can be handled in advance, and driving safety is prevented from being affected.

Description

technical field [0001] The invention relates to the field of inspection of underwater bridge pier diseases of railway bridges, in particular to a detection device for underwater bridge pier diseases of railway bridges using underwater robots equipped with acoustic, optical, mechanical equipment and water surface control and processing equipment, so as to realize the detection of surface defects of bridge underwater structures . Background technique [0002] There are a large number of river-crossing bridges on the railway, and the underwater pier foundation is a concealed project, which is easily affected by uncertain factors such as water erosion, drifting large rocks, or collisions with passing ships, resulting in holes, grooves, exposed steel bars, corrosion, damage and cracking Due to the complex underwater environment and the high difficulty of detection, the probability of problems in bridge piers is further increased. To ensure the safety of bridge piers, the railway ...

Problems solved by technology

[0002] There are a large number of river-crossing bridges on the railway, and the underwater pier foundation is a concealed project, which is easily affected by uncertain factors such as water erosion, drifting large rocks, or collisions with passing ships, resulting in holes, grooves, exposed steel bars, corrosion, damage and cracking Due to the complex underwater environment and the high difficulty of detection, the probability of problems in bridge piers is further increased. To ensure the safety of bridge piers, the railway engineering department needs to conduct regular diving exploration of underwater bridge piers. The current detection Most of the methods use divers to explore underwater, and divers face the following problems in underwater exploration: the underwater environment is complex and changeable, the flow of water is urgent and other issues, and underwater is often accompanied by a series of unknown risks, which are directly related to the life safety of divers ; and divers have short working hours, which cannot meet long-term underwater work tasks; underwater visibility is low, and divers consume too much cost for underwater observation; it is difficult to detect internal problems of bridges with naked eyes, which may easily lead to missed maintenance opportunities

Due to the high cost and high risk, most bridges have not been explored for a long time, resulting in the inability to grasp the situation of underwater piers in time, and unable to deal with related dangers in advance. When the disease is serious, it will also affect driving safety
