Seabed distance measuring device and detection method thereof

Abstract

The invention relates to the technical field of data measurement and display, in particular to a seabed distance measuring device and a detection method thereof. The seabed distance measuring device comprises a detection pile and a tubular plastic shell, a first conductive strip and a first conductive strip set are vertically arranged on the two opposite sides of the upper portion of the inner side wall of the shell respectively, a hollow detection rod is arranged in the shell in a sliding mode, and the outer side wall of the detection pile is sleeved with the lower end of the detection rod in a sliding mode; a first metal sheet and a second metal sheet which are communicated through a wire are arranged at the upper end of the first conductive strip, the first metal sheet is in sliding contact with the first conductive strip, and the second metal sheet is in sliding contact with the first conductive strip group. The device is high in detection accuracy, low in production cost and good in seawater corrosion resistance, the distance between the sea surface and the seabed and the water outlet height of the offshore oil platform deck can be dynamically monitored in real time, and the use and construction safety of the offshore oil platform is ensured.

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.
