The detection method of ice is continued to develop with the development of science and technology at present, can substantially divide 3 kinds at present: range estimation
Method, device survey method, telemetry.
Ocular estimate is pure artificial detection method, is observed according to the eyes of personnel and experience, is obtained completely in this way
Description result can have certain difference because of the difference of Observation personnel, and the range observed also has certain limitations, and observes number
There is very big difficulty according to quantification.
It is a kind of by by Observation personnel manual operations and reading what data carried out by instrument and tool that device, which surveys method, than
Such as directly measurement ice thickness of manually making a hole in the ice or drill.Although this measurement data is accurate objective, labor intensity is high, and risk is big,
The continuous and automatic of same place ice thickness cannot be monitored or the synchronised automatic of different location ice thickness is detected.
Telemetry is to be completely dependent on instrument itself to be observed, and using aircraft, satellite as platform, carries detection device, comes
Telemetering ice condition.Ice condition data are finally inversed by by the processing to the sound such as image, transmitting, light, electric signal.Its advantage is that not by weather,
Place limitation, is suitble to the Sea Ice Observations of large area.But simultaneously also because the range of observation is big, precision is not high, and telemetry is to part
The minor change of small range ice sheet structure can not reflect, and be very difficult to apply in the narrow river in inland, open channel and its water conservancy projects
The state of an illness observation.

Specific embodiment
With reference to the accompanying drawings and examples, further description of the specific embodiments of the present invention.Following embodiment is only
For clearly illustrating technical solution of the present invention, and not intended to limit the protection scope of the present invention.
As shown in Figure 1 and Figure 2, the present invention be it is a kind of detect river ice layer thickness device, including cuboid hollow body 1,
Strainer 2, funnel 3, the fixed device 4 in bank, channel ultrasonic instrument 5 and monitoring center 6, cuboid hollow body 1 are equipped with strainer
2, strainer 2 is equipped with funnel 3, and cuboid hollow body 1 is connect with the fixed device 4 in bank, and the fixed device 4 in bank and multichannel are super
Sound instrument 5 connects, and channel ultrasonic instrument 5 is connect with monitoring center 6, and the fixed device 4 in bank remains cuboid hollow body 1
Perpendicular to the state of the water surface.Channel ultrasonic instrument 5 supports the wireless transmission of solar powered and data-signal.
1 upper opening of cuboid hollow body, 1 inner hollow of cuboid hollow body, the side of cuboid hollow body 1
Equipped with several probes 7, several probes 7 are evenly distributed on the inner wall of cuboid hollow body 1, table in cuboid hollow body 1
Face is smooth, and spacing is 5mm between 20mm between probe 7.Strainer 2 and funnel 3 prevent dirty water or other impurity from entering cuboid
In hollow body 1, and it is able to maintain the circulation of 1 inner air and outer air of cuboid hollow body.Probe 7 is ultrasonic probe.
Probe 7 is monocrystalline longitudinal wave probe, and chip frequency is 0.2MHz between 20MHz.Cuboid hollow body 1 passes through pipe
Line 8 is connect with the fixed device 4 in bank.Cuboid hollow body 1 is stainless steel cuboid hollow body or organic glass cuboid
Hollow body.Probe 7 is fixed on cuboid hollow body 1 by screw or socket.
The present invention is mainly realized by the following technologies: by several monocrystalline longitudinal wave probes (wafer size be Φ 1mm extremely
30mm, frequency are 0.2MHz to 20MHz), are mounted on the hollow elongated cuboid hollow body for only having top to have opening
In, cuboid inner surface is smooth；Probe is fixed on a face of cuboid by screw or socket, and velocity of sound direction is perpendicular to right
Facade, the spacing between the short transverse arrangement of cuboid hollow body, probe of popping one's head in is 5mm to 20mm；The hollow appearance of cuboid
Water is injected in device, water did not had the probe of the top；Then cuboid hollow body is inserted perpendicularly into water, guarantees the spy of the top
Head and river horizontal plane flush.By the fixed cuboid hollow body of tooling, guarantee that cuboid hollow body is in vertical always
In the state of the water surface；Ultrasonic probe line is guided by pipeline to the channel ultrasonic instrument of river bank, channel ultrasonic instrument acquisition probe
After signal, signal is conducted by modes such as wireless transmissions to monitoring center, channel ultrasonic instrument is by solar powered.In monitoring
After the heart receives data, storing data, and pass through data processing and imaging software, each region ice layer thickness in real-time display river, and
Form distribution map.
When normal power-up works, ultrasonic probe persistently emits sound wave, and sound wave is conducted in cuboid hollow body, touched
It when cuboid hollow body opposite, reflects, ultrasonic probe receives reflected acoustic wave.When non-icing condition, the sound path L of water is answered
To pop one's head in the distance of cuboid opposite；Under ideal icing condition, it is assumed that ice medium is uniformly distributed, then the sound path of ice should be
1500L/3230, the velocity of sound for defaulting water is 1500m/s, and the velocity of sound of ice is 3230m/s, and the Ultrasound Instrument velocity of sound is set as always
1500m/s.But under normal circumstances, the forming process of ice is extremely complex, and dielectric distribution is uneven, and carries stomata or other miscellaneous secretly
Matter, structure is more special, and ultrasonic wave is in ice in communication process, and easily transmitting scattering, refraction etc. influence the feelings that normal route is propagated
Condition is found through experiments that, under icing condition, the sound path of deicing is that can also go out there are two types of situation outside 1500L/3230 such case
Existing, first is that ultrasonic probe equally can receive reflected acoustic wave, but sound path is less than above-mentioned sound path；Second is that ultrasonic probe can not connect
Reflected acoustic wave is received, no signal is shown on ultrasonic instrument；The appearance of these three situations is all the card for judging to have frozen herein
According to.If one of above-mentioned three kinds of situations all occur in n-th probe and probe before, the N+1 probe sound path is shown as L, then
Deducibility ice layer thickness is { 20 (N-1)+5 } mm.Signal is passed to monitoring center by Ultrasound Instrument, and monitoring center passes through data processing
And image processing software, by ice sheet real-time thickness and ice sheet distribution map real-time display.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
