Abstract
The utility model relates to a photoelectric instrument which can measure the suspended sediment content in water on site, comprising an underwater measuring probe, a control and display device on water and a connection cable. The underwater measuring probe comprises a light transmitter and a light receiver, with measuring the scattering and transmission of light with a fixed water path, the underwater measuring probe can determine the suspended sediment content in water, and the measured result is digitally displayed by a meter or continuously self record. The utility model can not only continuously measure the skin layer with being pulled by a ship, but also can vertically and continuously measure with being fixed point suspended, and the utility model can get the suspended sediment content in water which is continuously distributed in time and space in the water depth of 40 meters.
Description
The utility model is the photoelectric instrument of suspended sediment concentration in a kind of in-site measurement water, belongs to underwater survey instrument technical field.
In coastal zone exploitation, harbor work's construction, waterway dredging and marine environmental assessment, must grasp suspended sediment concentration and the distribution on time and space thereof in the water of relevant waters.In the past, suspended sediment concentration all adopted the sampling weight method in China's measurement water.The sampling weight method is that (as the sea) layering at the scene fixed point is gathered a certain amount of water sample, transports that the laboratory is filtered back, desalination, dries, weighs, and calculate suspended sediment concentration according to weighing results and volume of water sample, promptly outstanding husky concentration.
For the sampling weight method, the randomness of sampling is big, and operation is tired many, and it is long to obtain the measurement data cycle, influenced greatly by human factor, and measuring accuracy is difficult to assurance.And the sampling weight method can't be accomplished on time and space continuously.Particularly, outstanding husky for some, as flyash, mud etc., because its suspension time is short, sedimentation is very fast, almost is difficult to measure than accurate result with the sampling weight method.Therefore, ocean scientific research and engineering department need the instrument of suspended sediment concentration in a kind of in-site measurement water especially.
The purpose of this utility model is to release the on-the-spot instrument of measuring suspended sediment concentration in the water continuously in real time of a kind of energy.This instrument can carry out the top layer continuous coverage with ship towing, can fix a point again to hang and carry out vertical continuous measuring, can obtain 40 meters of the depth of waters with suspended sediment concentration in the water interior and continuous distribution on time and space, i.e. outstanding husky concentration in the water.
Outstanding husky analyzer is the ultimate principle design of basis light transmission generation differential declines in the different water of outstanding husky concentration in the water described in the utility model.When light transmits in water, because the scattering and the absorption of aqueous medium make light intensity decays.When a branch of directional light transmits in the uniform water of macroscopic view, its decay follow lambert's law (Lambert, Law):
I
t＝I
oexp（－αL）
α＝－ 1/(L) I
nI
t／I。
In the formula, I
oBe the radiation intensity of light beam outgoing place, L is the water journey length that light beam passes through, I
tFor light beam by radiation intensity after the L water journey, α is the attenuation coefficient of aqueous medium.
The decay of aqueous medium comprises the decay of outstanding grains of sand in the decay of water itself and the water.Test shows that particle concentration that same particle size distributes and attenuation coefficient α and scattered light intensity Is have the better linearity relation.The variation of attenuation coefficient α can be from by light radiation intensity I after the L water journey as can be seen from above-mentioned law formula
tVariation draw.This outstanding under water husky analyzer is measured respectively by light radiation intensity I behind the fixing water journey L
tDetermine outstanding husky concentration under water with forward scattering light intensity Is.
Outstanding husky analyzer is made up of underwater survey probe, control display waterborne and stube cable thereof in the water.
The underwater survey probing shell is that right cylinder is streamlined, and afterbody installs the cruciform tail vane additional, sees Fig. 1.There are optical transmitting set, optical receiver and measured zone three parts in underwater survey probe inside, sees Fig. 2.Optical transmitting set is the front portion of measuring sonde under water, comprises light source and parellel light beam system.Light source adopts common bulb; Parellel light beam system is made of lens combination, and the light that light source is sent becomes parallel beam.Parallel beam enters receiver by measured zone.Measured zone is a water container, between optical transmitting set and optical receiver, is linked to each other with optical receiver with optical transmitting set by watertight glass respectively, has not only guaranteed that light beam passes through but also water-tight.Light by measured zone produces decay (scattering and absorption).Optical receiver is the rear portion of measuring sonde under water, mainly by accepting lens and two silicon photocells are formed.A big silicon photocell is the hollow circular ring shape, receives forward scattering light Is; A little silicon photocell is placed on central authorities, receives transmitted light I
tOptical transmitting set and receiver are concentric integrated frame structure, guarantee the concentricity requirement of optical axis.Measuring water (as seawater) enters from underwater survey probe front end, enter measured zone through the optical transmitting set outside (cavity between optical transmitting set capsul and the underwater survey probing shell), through the optical receiver outside (cavity between optical receiver capsul and the underwater survey probing shell), flow out again from underwater survey probe afterbody.Cavity in the underwater survey probe has the intake-outlet that is provided with at diverse location up and down, makes the timely conversion of water that enters in the underwater survey probe cavity, and enters to eliminate bias light in the turnover of cavity inside spin.A right angle bend venthole is offered in measured zone casing upper end, can in time the bubble that enters in the underwater survey probe water be discharged.Underwater survey probe upper housing has two suspension ring outward, in order to hang measuring sonde by wirerope.Underwater survey probe lower casing has the suspension ring that hang weight outward.
Optical transmitting set is linked to each other with control display waterborne by heptcable with optical receiver.Input, output inserter that cable and underwater survey probe join all adopt the round section joint ring sealing means.
Control display waterborne is with the scattered light of silicon photocell conversion and the electric signal of transmitted light, through suitably amplify, calculation process, by record display system record and show measurement result automatically.Data presentation can have three kinds of devices: 1. digital voltmeter shows outstanding husky concentration in the water that transmission output and scattering output characterizes; 2. a two X-Y recorder, outstanding husky concentration in the self-recording water continuously; 3. single card microcomputer data acquisition system (DAS), the field real-time acquisition measurement data deposits tape in, and links to each other with computing machine, is convenient to data and preserves and analytical calculation.
