Abstract
The present invention relates to migration sediment concentration of the nearly end, a kind of shallow sea and granularity real-time detection device.Comprise eight of being fixed on the circle ring chamber by circumference 45 angle intervals, be the cylinder that radiation is laid, concentration probe and eight granularity probes are set on this cylinder, and be connected with the corresponding data acquisition treating apparatus via cable, above-mentioned cable and corresponding data acquisition treating apparatus all are encapsulated in the circle ring chamber.The present invention who constructs thus is rational in infrastructure, cost is low, solved different directions of the nearly end, shallow sea easily with the sediment concentration of passing, the motion of saltation form and the problem that size-grade distribution is difficult to on-the-spot real-time detection, so that the relation of split-phase starting sediment grain size and hydrodynamic condition, for seabed scouring research and retrogression of coast protection provide reliable scientific basis.
Description
Technical field
The present invention relates to the measurement mechanism of the nearly bottom sediment characteristic parameter in shallow sea, specifically migration sediment concentration of the nearly end, shallow sea and granularity real-time detection device.
Background technology
The nearly bed mud sand in shallow sea is migrated under wave and action of ocean current, often causes washing away or depositing of sea bed, and the marine engineering facility is worked the mischief.Existingly catch husky device and be widely used in catching of the nearly end, shallow sea migration silt, after generally getting up through a damp cycle, take back the sediment yield and the granulometric composition (size-grade distribution) of different directions in the whole tide of the lab analysis cycle again, thisly catch husky device and can not monitor sediment yield and granulometric composition (size-grade distribution) under the different sea situations of different in flow rate in real time; Though there are laser levitation body sonar and laser levitation body size-grade distribution sonar in the modern times in addition, can monitor the concentration and the size-grade distribution of suspension in the water respectively, but they must utilize hull to survey the concentration and the granularity of fine grained suspension in the water, then are difficult to survey for the sediment concentration and the size-grade distribution of the nearly end with passing, the motion of saltation form.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, the sediment concentration of the nearly end migration in a kind of real-time monitoring shallow sea silt at different time, different directions is provided.
Another object of the present invention is in the monitoring sediment concentration, can also monitor husky size-grade distribution, so that the relation of split-phase starting sediment grain size and hydrodynamic condition.It is the real-time detection device of migration sediment concentration of the nearly end, shallow sea and granularity.
The data acquisition processing device that the present invention utilizes existing granularity probe and concentration to pop one's head in and match conveniently is applied to the real-time measurement of migration sediment concentration of the nearly end, shallow sea and size-grade distribution with it.
Therefore, the present invention includes eight cylinders that are the radiation laying by circumference 45 angle intervals that are fixed on the circle ring chamber, the concentration probe is set on this cylinder, and be connected with the corresponding data acquisition treating apparatus via cable, above-mentioned cable and corresponding data acquisition treating apparatus all are encapsulated in the circle ring chamber.
Consider the on-the-spot size-grade distribution that realizes the silt of real-time detection process simultaneously, be radiation by circumference 45 angle intervals again and be laid in eight granularity probes on the circle ring chamber, and the granularity probe can be separately positioned on the same circle ring chamber with above-mentioned concentration probe.
The present invention who constructs thus is rational in infrastructure, cost is low, realized and solved different directions of the nearly end, shallow sea easily with the sediment concentration of passing, the motion of saltation form and the problem that size-grade distribution is difficult to real-time detection, so that the relation of split-phase starting sediment grain size and hydrodynamic condition, for seabed scouring research and retrogression of coast protection provide more reliable scientific basis.

Embodiment
As Fig. 1, the present invention includes eight cylinders 3 that are the radiation laying by circumference 45 angle intervals that are fixed on the circle ring chamber 2, concentration probe 5 and granularity probe 4 are set on this cylinder 3, and be connected with corresponding data acquisition device 6 via cable 7, above-mentioned cable 7 and corresponding data acquisition device 6 all are encapsulated in the circle ring chamber 2.Get final product above-mentioned degree and the size-grade distribution of on-the-spot real-time detection like this through the silt of device different directions.
As Fig. 2, for making things convenient for technology, above-mentioned concentration probe and granularity are popped one's head in the position of same circle ring chamber are installed, and are installed on the two ends of same circle ring chamber usually, and both positions can exchange.Above-mentioned circle ring chamber 2 is the circular body that round metal cavity or plastic tube curve, and cable and data collector all seal and put within it.
Consider the needs of on-the-spot stable detection, be fixed with the silt support 1 of being convenient to insert the seabed in the bottom of circle ring chamber 2.So that be fixed in the silt of seabed.
An above-mentioned granularity probe 4 of settling in cylinder 3 is MASTER equigranular sensors.
Above-mentioned concentration probe 5 is suspended sediment sensors such as LISST.
As Fig. 2, concentration probe and granularity probe are housed in the cylinder 3, can monitor concentration and granularity in real time, and data transfer to data collector 6 preservations through cable 7 simultaneously by the silt of cylinder.The cylinder 3 that includes concentration probe 5 and granularity probe 4 on the described circle ring chamber (2) is symmetrical arranged more than eight at least, as 12 etc., so that the concentration and the size-grade distribution of the migration silt of real-time detection seabed different azimuth.
Claims (2)
1, migration sediment concentration of the nearly end, shallow sea and granularity real-time detection device, it is characterized in that it comprise eight of being fixed on the circle ring chamber (2) by circumference 45 angle intervals, be the cylinder (3) that radiation is laid, and concentration probe (5) and granularity probe (4) is set on this cylinder (3), and be connected with corresponding data acquisition device (6) via cable (7), above-mentioned cable (7) and corresponding data acquisition device (6) all are encapsulated in the above-mentioned circle ring chamber (2).
2, migration sediment concentration of the nearly end, shallow sea as claimed in claim 1 and granularity real-time detection device is characterized in that being fixed with the support (1) of being convenient to insert seabed silt in the bottom of above-mentioned circle ring chamber (2).
