Problems solved by technology

However, in the actual deployment process, due to the complex and special terrain of the steep slope, the conventional sitting-bottom ADCP support cannot have a stable sitting posture. The measurement results of the ADCP on the bracket will have a large error, and even cause the measured data to be invalid

Abstract

The invention relates to a slope wave flow measuring device and deployment method based on a seabed foundation. The slope wave flow measuring device comprises an anchor system, wherein the structure of the anchor system comprises a first anchor chain, one end of the first anchor chain is provided with a first anchor claw, the other end of the first anchor chain is provided with a second anchor claw, the first anchor chain installed at the position of the second anchor claw is connected with the second anchor chain, a tail end connecting piece is arranged at the end of the second anchor chain,a buoyancy device is arranged at the tail end connecting piece, the buoyancy device structurally comprises a buoyancy cylinder, a support is arranged inside the buoyancy cylinder, an ADCP is fixed atone end of the support, an acoustic releaser is fixed at the other end of the support, a cabin rope is fixed on the acoustic releaser, the cabin rope extends out of the buoyancy cylinder, a pluralitycircles of cabin ropes are sequentially wound on the periphery of the buoyancy cylinder from top to bottom, and the tail end connecting piece is connected at the bottom of the buoyancy cylinder. According to the device and method, the problem of safety of distribution of the wave flow measuring device at the steep slope is solved, the measuring stability and the data accuracy are ensured, and therecycling reliability is considered.

Description

technical field [0001] The invention relates to the technical field of underwater posture monitoring, in particular to a seabed-based steep-slope wave-current measurement device and a deployment method. Background technique [0002] Acoustic Doppler Current Profilers (English: Acoustic Doppler Current Profilers, referred to as ADCP) is an instrument that uses the acoustic Doppler effect to measure the velocity of a water flow profile. ADCP includes a self-contained ADCP. The self-contained ADCP is installed on the bottom of the water and is supported and fixed by a fixed bottom-mounted bracket. This type of bottom-mounted bracket is a relatively common and reliable installation method. The type ADCP itself is not easy to shake, can ensure the accuracy of data measurement, and is not easily affected by external natural conditions. After deployment, short-term detection and maintenance are not required. [0003] The steep slope topography of the seabed leads to great changes ...
