Equipment used for observing bridge underwater structure object

Abstract

The invention belongs to the technical field of underwater observation, and particularly relates to equipment used for observing a bridge underwater structure object. The equipment is characterized bycomprising an observing carrier, a control system arranged on the observing carrier, an information acquisition system and a protection cover, the observing carrier comprises a remote control ship model, an anti-impact plate, an aquatic plant prevention screen arranged at the bottom of the rear end of the remote control ship model, a transverse bracket which is arranged on the remote control shipmodel, a platform plate, a sonar bracket arranged on the platform plate, a telescopic rod which is arranged at one end of the transverse bracket, a top fixed pulley and a rotary fixed pulley which are arranged on a first-level rod of the telescopic rod and a hoisting frame which is arranged at the top outside the telescopic rod. Inspection check work of the bridge underwater structure part is perfected, so that the check is simple and operable, based on practice of daily check work of all water-passing and water ponding bridge lower structures, and a sonar detector and an underwater camera are integrated with a remote control bearing ship model and a telescopic frame and cooperated with a corresponding image recognition system for recognition and detection.

Description

technical field [0001] The invention belongs to the technical field of underwater observation, in particular to a device for observing bridge underwater structures. Background technique [0002] At present, the observation of the underwater structure of bridges in China is still vacant, and there is no systematic and mature diagnostic technology to diagnose and detect the underwater foundation of bridges. The main detection methods at this stage are as follows: [0003] In June 2008, the Highway Planning, Survey and Design Research Institute of the Sichuan Provincial Department of Communications used the Blue Whale brand complete set of underwater TV equipment produced by the 750 Experimental Research Institute of China Shipbuilding Industry Corporation, and after simple processing of supporting equipment, the underwater camera was controlled on board. The underwater imaging observation system has detected the dropped girders and underwater piers of the Miaoziping Ejiang Br...

Problems solved by technology

[0003] In June 2008, the Highway Planning, Survey and Design Research Institute of the Sichuan Provincial Department of Communications used the Blue Whale brand complete set of underwater TV equipment produced by the 750 Experimental Research Institute of China Shipbuilding Industry Corporation, and after simple processing of supporting equipment, the underwater camera was controlled on board. The underwater imaging observation system has detected the dropped girders and underwater piers of the Miaoziping Ejiang Bridge after the "512" Wenchuan Earthquake. Due to factors such as water depth and light, the images are blurred, and there are errors and errors in detection and judgment. difficulty

This represents the highest level of observation of underwater structures at present, but it is expensive and difficult to promote, and cannot be used as equipment for daily inspection

[0005] In "Detection Methods and Engineering Examples of Underwater Pile Foundations in Service Structures", Sun Hui discussed the detection methods of pile foundations in service, expounded the advantages and disadvantages of reflected wave method, underwater camera method, and underwater topography method, and pointed out that Underwater acoustic wave imaging system, low-light and laser active imaging technologies are expected to be used in turbid water imaging and replace the three traditional visual detection technologies. However, this study only summarizes the current detection methods and future development directions, and does not substantive technical research
