Description
Technical field
The present invention relates to a kind of seawater velocity measuring devices, and in particular to a kind of adaptively to bottom out hanging type flow measurement
Instrument.
Background technology
Bottom seawater flow velocity is typically referred to from seabed certain altitude（Such as 0.5 meter）The flowing velocity of water layer.It is seabed electricity
The ocean engineerings such as cable and the dispensing of pipeline laying, sand exploitation, sea-farming location determination and artificial marine habitat are built necessary when addressing
One of key factor of consideration, therefore the correctness of bottom seawater measurement of rate of flow result is directly related to above-mentioned ocean engineering and builds
If the reasonability of addressing.
Currently, measuring the common instrument of bottom seawater flow velocity has acoustics doppler flow speed analyzer and electromagnetism Flow speed measurer
It measures.Acoustic Doppler flow meters need to only fix exterior measuring on the quarter and can be measured in certain depth of water（It is similar
Sonar）, but since there are blind areas（It is divided into upper blind area and lower blind area）；Usually lower blind area is the 6% of the depth of water（Such as when the depth of water is 20
Meter Shi, then its blind area is 1.2 meters）, thus in most cases can not be direct to being carried out from seabed only 0.5 meter or more water layer
It measures.
Blind area is not present in electromagnetism Flow speed measurer, can directly be measured to bottom seawater flow velocity.Current electromagnetism flow velocity
The following two modes of measuring instrument generally use：Mode one：In electromagnetism Flow speed measurer underhung counterweight, and will be electric by rope
Near Sea Bottom is leaned in the decentralization of magnetic Flow speed measurer.This measurement method not only needs to measure in advance sea water advanced, inconvenient；It is more important

Accurate location, and electromagnetism Flow speed measurer glances off, and electromagnetism Flow speed measurer can not be made to be in vertical outstanding when measuring
The state of extension, this will influence electromagnetism Flow speed measurer measurement accuracy.
Mode two：Electromagnetism Flow speed measurer is mounted on installation rack, and rope will be installed and arrive seabed below rack；This
Kind measurement method is although easy to operate, but when sea bottom surface is a slope or is uneven, is placed in the installation rack in seabed often
Also it will glance off, be glanced off so as to cause electromagnetism Flow speed measurer, and equally affect electromagnetism Flow speed measurer and measure essence
Degree.
