Seabed ranging device and detection method thereof

Abstract

The invention relates to the technical field of data measurement and display, in particular to a seabed ranging device and a detection method thereof. The seabed distance measuring device includes a detection pile, a tubular plastic shell, a first conductive strip and a first conductive sheet group are vertically provided on the upper and opposite sides of the inner wall of the shell, and a hollow hole is slidingly provided in the shell. The detection rod, the lower end of the detection rod is slidably sleeved on the outer wall of the detection pile, and the upper end is provided with a first metal sheet and a second metal sheet connected by a wire, and the first metal sheet is connected to the first metal sheet. The conductive strips are in sliding contact, and the second metal sheet is in sliding contact with the first conductive sheet group. The invention has high detection accuracy, low production cost and good seawater corrosion resistance, can dynamically and real-time monitor the distance between the sea surface and the seabed and the water outlet height of the deck of the offshore oil platform, and ensures the use and construction safety of the offshore oil platform.

Description

technical field [0001] The invention relates to the technical field of data measurement and display, in particular to a seabed ranging device and a detection method thereof. Background technique [0002] With the development of offshore oil fields, offshore oil platforms have been widely used and have been distributed in almost every sea area of ​​the world. Offshore oil platforms are generally piled platforms, which are supported by piles driven into the seabed so that they can withstand external forces such as wind, waves, and currents at sea. [0003] The following problems exist in the use of offshore oil platforms: First, waves will generate significant dynamic pressure on the seabed during propagation, and some seabeds may become unstable under dynamic pressure. When the seabed is unstable, the seabed will The soil on the surface migrates with the action of waves, which reduces the penetration depth of piles into the seabed, seriously affecting the safety of offshore ...

AI Technical Summary

Problems solved by technology

[0003] The following problems exist in the use of offshore oil platforms: First, waves will generate significant dynamic pressure on the seabed during propagation, and some seabeds may become unstable under dynamic pressure. When the seabed is unstable, the seabed will The soil on the surface migrates with the action of waves, which reduces the penetration depth of piles into the seabed, seriously affecting the safety of offshore oil platforms; secondly, seabed subsidence may occur when the seabed is unstable, and seabed subsidence will Causes the overall sinking of the offshore oil platform, resulting in insufficient deck water height of the platform. When the deck water height is insufficient, the offshore oil platform is greatly affected by the waves, and the stability and construction safety are poor.
