Description
Technical field
Fixed the present invention relates to a kind of fixed mount, more particularly to a kind of doppler velocimeter measured for ocean flow velocity
Frame.
Background technology
Deep water mesh cage is generally arranged at compared with deep-sea domain, is a kind of high investment, high production, the breeding facility of excessive risk.Cultivation
Capacity is big, culture benefit is deep-water net cage culture significant advantage the most well.Develop deep-water net cage culture turns into China coast
Province accelerates transformation fishery economic development pattern, significantly expands the important measure in sea farming space, and maximum net cage produces fish amount per year
Super 60t/ casees.But the deep-water net cage culture of high capacity highly effective benefit is realized, the net cage addressing of science, structure is be unable to do without and sets safely
Meter and efficiently aquaculture management, and the above is intended to be related to the scientific measurement of cage culture marine site flow velocity, such as deep water mesh cage
Should not be arranged on the marine site of larger flow velocity, big flow velocity be likely to result in etting deformation it is serious cause cultured fishes because of activity space not
Enough so as to influence fish growth and the increase death rate.
The flow velocity method of measurement Sea Area of Net-cage Culturing mainly has two kinds at present.One kind is hand-held measurement, by flow velocity
Instrument is tied up stretches to the progress hand-held measurement of below the water surface on a montant.This metering system is typically that staff is small at one
Operated on ship, do not possess the possibility that can continuously measure for a long time.Another is the measurement of ship side fixed-point type, and current meter is tied
Board carries out section flow velocity measurement, although this mode can realize continuous measurement for a long time, but surface velocity is often
Being highly susceptible to influence of ship-body causes the inaccurate of measurement data, and to ensure that the probe vertical of current meter is downward, outfit
Workboat tonnage should not be too small, and the influence for being otherwise highly susceptible to small stormy waves causes waving for hull, and economy is not good.In addition,
Both the above metering system can not measure the ocean flow velocity under severe sea condition in real time because of security consideration.
The content of the invention
The technical problems to be solved by the invention, are just to provide a kind of doppler velocimeter for the measurement of ocean flow velocity and consolidate
Determine frame, can be achieved ocean current speed under harsh ocean operating mode it is prolonged it is continuous, accurately measure.
Above-mentioned technical problem is solved, the technical solution adopted in the present invention is as follows：
A kind of doppler velocimeter fixed mount measured for ocean flow velocity, including for fixing in doppler velocimeter
Between support body, the protect-ing frame structure in plane, top support body and bottom support body；Top and the bottom are respectively equipped with fixture block in middle frame body, often
Individual fixture block includes two clamping blocks, and each clamping block is provided with the breach being adapted with the neck on doppler velocimeter and peace
Through hole is filled, jaws is formed the fixture block by two recessed fixture blocks through running through screw rod in installation through-hole with respect to clamping；The middle frame
