Description

The anti-interference measurement mechanism of surface seawater flow velocity
Technical field
The present invention relates to a kind of seawater velocity measurement mechanism, be specifically related to a kind of anti-interference measurement mechanism of surface seawater flow velocity.
Background technology
Surface seawater flow velocity refers to the marine stream speed of water layer between 0.1 meter ~ 1 meter, below sea.The measurement of surface seawater flow velocity has great importance in national defence, shipping, fish production etc.The surveying instrument of surface seawater flow velocity has acoustics doppler flow speed measuring instrument and electromagnetism Flow speed measurer (electromagnetism flow measurement is one of traditional flow-speed measurement method) etc.Acoustic Doppler Flow speed measurer can be measured the flow velocity of multiple water layer due to it simultaneously and be widely used, and is at present more advanced Flow speed measurer, but acoustic Doppler Flow speed measurer exists and measures blind area and (measure dividing of You Shang blind area, blind area and lower blind area; The thickness of upper blind area is not only relevant with the degree of depth that probe is put under water, also relevant with factors such as its frequency of operation, setting parameters in observation process, it is minimum sounds the depth of the water at least more than 1 meter), this makes it directly cannot measure top layer seawater velocity (can only be obtained by estimation, its accuracy cannot ensure).
Electromagnetism Flow speed measurer is a kind of traditional Flow speed measurer, and there is not blind area when it is measured directly can measure top layer seawater velocity; When using electromagnetism Flow speed measurer to measure top layer seawater velocity, be laid in the water layer apart from sea certain depth by hang.The hang that current electromagnetism Flow speed measurer adopts when measuring generally includes following two kinds of modes: mode one, utilize existing offshore drilling platform or other fixed rack that can use as erecting frame, electromagnetism Flow speed measurer is measured the water layer be fixedly laid in apart from sea certain depth; Which is an effective surface seawater flow-speed measurement method, it can effectively avoid electromagnetism Flow speed measurer, with wave, the relative motion of obvious horizontal direction occurs, ensure that electromagnetism Flow speed measurer is in fixing position when measuring, thus improve the reliability of the data obtained; But which is mayed come by something with luck, but not by searching for it usually.
Mode two, the method stretches out a support in the ship side side of surveying vessel, then utilizes this support and rope to transfer on sea by flow rate measuring device; Flow rate measuring device generally includes ball float and is suspended on the electromagnetism Flow speed measurer below ball float by connecting line.Transfer to sea on by rope by flow rate measuring device when measuring, the upper end of rope is fixed on the support that stretches out ship side side, and the other end is adjacent with ball float; Ball float is across the sea floating, and electromagnetism Flow speed measurer is suspended on below ball float.Which is a kind of surface seawater fluid-velocity survey mode conventional at present, although it can need to measure the surface seawater flow velocity in selected marine site according to test; But because in measuring process, surveying vessel can with wave generation drift, cannot fix, thus cause the electromagnetism Flow speed measurer of flow rate measuring device also to produce drift thereupon, thus there is the relative motion of horizontal direction in electromagnetism Flow speed measurer in measuring process, this makes surveyed flow velocity and actual flow velocity have larger discrepancy, and measuring accuracy is low.
