Problems solved by technology

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

Embodiment 1

[0034] Figure 1a It is a schematic structural diagram of a base station based on an underwater inspection system provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of detecting leak points of underwater pipelines. The underwater inspection system can be used as a subsystem of the underwater pipeline transmission system to assist in the transmission of media in the pipeline. Typically, in an offshore oil and gas production system, the underwater inspection system can be used to detect leakage of submarine pipelines point, assisting in the transfer of oil and gas from the seabed to the land. The base station based on the underwater inspection system is installed on the underwater pipeline, and it is specifically realized as a device that provides navigation and energy supply for the underwater mobile inspection device. During the underwater inspection process, the base station can communicate with the underwater mobile inspection de...

Abstract

The embodiment of the invention discloses a base station based on an underwater routing inspection system and a routing inspection method thereof. The base station comprises a main controller, a positioning communication module and an energy control module, wherein the main controller is electrically connected with the positioning communication module which is used to generate a first positioninginstruction or a second positioning instruction according to the sound wave signal requesting positioning or charging sent by the routing inspection device, and then sent to the positioning communication module; the positioning communication module is used for sending positioning sound wave signals or infrared signals to the routing inspection device based on the first positioning instruction or the second positioning instruction; the energy control module is electrically connected with the main controller and is used for electrifying the electromagnet on the routing inspection device, a mutual attraction acting force is generated between the permanent magnet at the charging port and the electromagnet, so that the routing inspection device and the charging port are in butt joint and are charged. According to the technical scheme of the embodiment of the invention, real-time leakage point detection can be carried out on the pipeline rapidly and accurately, and loss of pipeline transmission media is reduced.

Description

technical field [0001] Embodiments of the present invention relate to inspection technologies, and in particular to a base station based on an underwater inspection system and an inspection method thereof. 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 early stage of pipeline leakage, due to t...
