Problems solved by technology

[0004] However, in the initial stage of pipeline leakage, due to the small scale of the leakage point, it is difficult to quickly and accurately locate the position of the pipeline leakage point due to the limitation of the installation position and number of detection devices in the existing technology. When it is discovered, it has already caused the loss of the pipeline transmission medium, and even caused some pollution to the water quality around the pipeline.

Abstract

The embodiment of the invention discloses an underwater inspecting system. The system comprises an inspecting device and a base station; the base station is arranged on a pipeline and used for transmission a positioning sonic wave signal to the inspecting device, and the inspecting device is used for receiving the positioning sonic wave signal and determining the relative position of a pipeline leakage point and the inspecting device according to the movement of the positioning sonic wave signal towards the base station and the real-time collection of the sonic wave signal of the pipeline leakage point in the moving process; the inspecting device is further used for transmitting a sonic wave signal requesting for charging, receiving an infrared signal to determine the moving direction towards a charging port of the base station based on the infrared signal, and butting with the charging port of the base station based on the moving direction to receive energy provided by the base station, and the base station is further used for transmitting the infrared signal to the inspecting device based on the sonic wave signal requesting for charging. The system has the advantages that the position of the pipeline leakage point can be rapidly and accurately positioned to reduce the loss of a pipeline transmission medium.

Description

technical field [0001] The embodiments of the present invention relate to inspection technologies, and in particular to an underwater inspection system. Background technique [0002] Since the 1950s, the amount of underwater pipeline laying has been increasing, from the past laying across rivers to the current laying across deep seas, realizing the transmission network of underwater oil and gas. [0003] Because underwater oil and gas pipelines are soaked in water, they will be corroded by chemicals and organisms. In the long run, the wall thickness of the pipeline will gradually decrease, which will lead to the leakage of the transmission medium in the pipeline. The existing technology mainly detects the pressure and flow of the pipeline by installing a detection device on the pipeline, so as to determine the position of the leakage point of the pipeline. [0004] However, in the initial stage of pipeline leakage, due to the small scale of the leakage point, it is difficul...
