Description
Technical field
The utility model relates to hydraulic model test technologies, in particular to throw mud mould type under water and test landform real-time measurement system
System.
Background technique
It throws in mud model test under water, carrying out bathymetric surveying will be seen that the influence for throwing mud to underwater topography, be
Influence, guidance of the further research throwing mud to river and sediment movement throw mud ship throwing mud mode and provide foundation, and importance is not sayed
And it explains.Hydraulic model bathymetric surveying is more demanding for measuring system, on the one hand, due to the ratio of hydraulic model in laboratory
Ruler is generally large, and the 1mm on model may correspond to that prototype 100mm is even more big, therefore positioning and survey for measuring system
Deep required precision is higher；On the other hand, it for reaction model underwater topography as accurately as possible, generally requires and arranges more survey
Point, while needing to guarantee the synchronism of data again, therefore it is required that measuring system measuring speed with higher.
The bathymetric surveying method of hydraulic model mainly includes contact and contactless two major classes in current experiment room.
The former generally measures underwater topography using the contacts Topographical indicator such as impedance Topographical indicator and photoelectricity Topographical indicator.Its advantage is that whole
Bulk measurement precision is higher, so be widely used.But since this kind of conventional contact Topographical indicator is needed measuring instrument and model
The contact of bottom surface landform, is easy to bring local dip.By taking impedance Topographical indicator as an example, when use, needs to insert a probe into silt circle
Face, the variation by measuring resistance obtain the Terrain Elevation of the measurement point.If measurement point is excessively intensive, just inevitably result in
Some areas measurement error is larger.Furthermore the measuring speed of conventional contact Topographical indicator is also relatively slow, it is difficult to realize underwater topography
Real-time measurement.
And the latter then mainly includes underwater laser ranging and supersonic sounding two ways.Supersonic sounding is by ultrasonic wave to water
Lower landform is scanned, and obtains each measuring point ultrasonic reflections time by instrument, so obtain each point to instrument distance, and according to
Instrumented site is scaled measuring point coordinate, and measuring speed is very fast.However, speed of the supersonic sounding dependent on sound transmission, and velocity of sound
Again vulnerable to temperature, water quality impact；In addition, outside noise may also have an impact supersonic sounding, therefore its low measurement accuracy.
Underwater laser range measurement principle is similar with supersonic sounding, and compared to supersonic sounding, laser is not vulnerable to temperature and extraneous influence, measurement speed
Degree is very fast, and precision is also higher under normal circumstances.It is contemplated that silt can expand in water during throwing mud model test under water
It dissipates, tends to interfere with laser propagation, thus the accuracy for throwing laser ranging in mud model test under water is unable to get guarantee.Together
Reason, the influence to sediment that ultrasonic wave can also be spread, it is difficult to guarantee the accuracy of ranging, and this quasi-instrument is relatively expensive.Therefore
Although various Topographical indicators are widely used in most of hydraulic model test, the underwater particularity for throwing mud test makes its hardly possible
To be applied to this, this is also why many research institutions are when carrying out underwater throwing mud test, is still carrying out people using Sounding Rod
Work bathymetric surveying.
Utility model content
The purpose of the utility model is to overcome underwater topographies when carrying out underwater throwing mud model test in current laboratory to survey
The difficulty of amount provides the technology for the landform that one kind is efficient, reliable, real―time precision measurment throws mud formation under water, for throwing mud mould under water
Type test provides technical support.
The technical scheme adopted by the utility model is a kind of underwater mud mould type of throwing tests landform real-time measurement system, packet
Include underwater throwing mud mould type, measuring system and Image Acquisition and identifying system；
The underwater throwing mud mould type includes that sink, remote control throwing mud ship model and model sasnd, the remote control are thrown mud ship model and used
In the loading model sasnd and the model sasnd of dishing out；
The measuring system includes measurement plate and pulley with probe；The probe is provided with several and is in rectangular
It is fixed in the measurement plate；The measurement plate is placed in the sink, and quadrangle is connected on the pulley by rope；Institute
It states there are four pulley settings, the top quadrangle of the sink is separately fixed at, for controlling the measurement plate raising and lowering；
Described image acquisition and identifying system include video camera, data line and computer；The video camera is for real-time
Record cast sand siltation situation is shot, the video camera is connected by the data line with the computer, by information reality
When be transferred to the computer.
Further, the probe is the metal needle of diameter 2mm, and be divide into upper part and lower part: top is provided with for identification
The label of probe location, lower part are provided with for measuring the scale marker for throwing the Terrain Elevation that mud is formed.
Further, the video camera setting has four, is uniformly arranged on outside the sink；Every video camera is only remembered
Record the capped situation of the probe of a quarter.
The beneficial effects of the utility model are: on the one hand, during throwing mud under water, silt is first in water around
Spread then almost vertical drop, as long as guaranteeing the enough depth of water, the spy when silt is vertically fallen in measurement plate, in measurement plate
For throwing, the influence of topography that mud is formed is minimum, has both avoided the excessive contact disturbance of conventional contact Topographical indicator bring and part accidentally
Difference, and the accuracy of measurement will not be influenced because of sediment diffusion；On the other hand, the utility model is mutually matched by 4
It the capped situation of probe and is input on same computer in video camera sync pulse jamming measurement plate and is automatically synthesized realtime graphic, both
Measurement efficiency is improved, and test process can be made more intuitive, provides guidance to throw the throwing mud mode of mud ship.
