AI Technical Summary

Problems solved by technology

At present, there are a variety of non-destructive testing methods for concrete floor, but because the concrete floor of hydraulic structures has been underwater for a long time and the water depth is relatively deep, even as deep as about 10 meters, there are no intuitive testing conditions, which limits many conventional testing methods ; The existing artificial diving operation detection method has high risk, difficulty, and high cost; and thick deposits are easily formed on the surface of the bottom plate, which also brings inconvenience to the detection

Embodiment 1

[0031] In this embodiment, an intelligent detection device for underwater dredging of hydraulic structures is disclosed, including: a dredging tank, a sewage pump, and an image acquisition device. The dredging tank is placed at the position of the underwater structure to be detected, and the The sewage pump is placed in the dredging tank, and the sewage pump is connected to the sewage pipeline. The muddy water pumped out by the sewage pump is discharged through the sewage pipeline. The image acquisition device is fixed on the dredging tank through the bracket assembly, and is used to capture the surface of the underwater building. Image, through the collected surface images of underwater buildings to determine whether there are defects on the surface of underwater buildings.

[0032] Further, an openable cover plate is arranged on the dredging cylinder, and the dredging cylinder, the sewage pump and the cover plate are all connected with lifting ropes.

[0033] Further, a buoy...

Embodiment 2

[0075] In this embodiment, an intelligent detection method for underwater dredging of hydraulic structures is disclosed, including:

[0076] Place the dredging tank fixed with the image acquisition device at the position where the underwater structure is to be detected;

[0077] Locate the sinking position of the dredging cylinder according to the buoy;

[0078] According to the positioning position of the buoy, put the sewage pump into the dredging tank;

[0079] Underwater dredging is carried out through the sewage pump, and the muddy water from dredging is discharged from the sewage pipeline;

[0080] Collect the surface image of the underwater building through the image acquisition device;

[0081] According to the collected surface images of underwater buildings, it is judged whether there are defects on the surface of underwater buildings.

Abstract

The invention discloses an intelligent detection device and method for underwater dredging of a hydraulic structure. The device comprises a desilting cylinder, a sewage pump and an image collecting device used for collecting underwater structure surface images, wherein a cover plate capable of being opened and closed is arranged on the desilting cylinder, the sewage pump is installed in the desilting cylinder, the sewage pump communicates with a sewage pipeline, muddy water pumped by the sewage pump is discharged through the sewage pipeline, and the image collecting device is fixed on the desilting cylinder through the support assembly. Underwater dredging is performed through the sewage pump, and the surface image of the underwater building is acquired through the image acquisition device, so that the surface defects of the underwater building can be intuitively observed.

Description

technical field [0001] The invention relates to the technical field of underwater detection of hydraulic structures, in particular to an intelligent detection device and method for underwater dredging of hydraulic structures. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Hydraulic structures play a vital role in water resources dispatching, and ensuring the safe operation of hydraulic structures is a key task of hydraulic engineering management. Among them, the bottom plate and gates of hydraulic structures are subjected to repeated water loads for a long time underwater, and they are immersed in water for a long time, which is prone to safety hazards such as structural aging. In order to ensure the safety of the operation of hydraulic structures, it is very important to detect the water-soaked parts of hydraulic structures, especially...
