Abstract
The invention discloses a deep-sea high-magnification underwater suspended particle imager, wherein a long-distance microscope objective of an underwater camera is close to a front end cover of a case, and a digital eyepiece is arranged behind the long-distance microscope objective. A sampling device is arranged at the outside of the front end cover of a cylindrical case, and the sampling device comprises an elevator mechanism, an LED (Light Emitting Diode) light source, a stator plate, a rotor plate and a ring seal cover. The stator plate is fixed at the external side of the end cover of the case, the rotor plate is fixed at a lower opening of an LED light source fixed hood, the LED light source is fixed at the centre of the light source fixed hood, the ring seal cover is located at the outside of the light fixed hood, the light source fixed hood is connected with the elevator mechanism, and the elevator mechanism drives the light source fixed hood to move up and down. Action of the elevator mechanism is controlled by a control circuit of a microprocessor. In the imager, the long-distance microscope objective is used, so that thickness of the stator plate between an objective lens and the rotor plate is increased, the conflict between the deep-sea pressure tolerance and the magnification is solved, and the imager can shoot the suspended particles, of which the size is less than 5 micrometers, in deep sea; an automatic closing sampling mechanism is also used, thus, the problem of blurring of the captured images caused by flowing seawater is avoided.
Description
Technical field
The present invention relates to ocean measuring instrument, relate to particularly that suspended particle in the in-site measurement seawater distributes and the instrument of concentration.
Background technology
Suspended particulate substance has material impact to marine environment in the seawater, and the detection of suspended particulate substance is the important content of marine environmental monitoring, also is the important content of coastal ocean environmental improvement.Marine Environmental Governance needs on-the-spot seawater suspended particulate substance data, all in-site measurement seawater suspended particulate substance is listed as important content in standard of marine survey and the marine monitoring standard, and for this reason, the surveying instrument of on-the-spot suspended particulate substance is further paid attention in the water.
At present, the surveying instrument of suspended particle mainly is to utilize optical means to measure in the seawater, utilizes the dispersion image that obtains suspended particle in the water perhaps to pass through thin layer seawater micro-imaging, to measure the distribution and the concentration of suspended particulate substance in the seawater.Be complicated funtcional relationship between the size of the size of suspended particle dispersion image speckle and actual suspended particle in the water, calculate loaded down with trivial detailsly that error is bigger; Utilization is to the distribution and the concentration of suspended particulate substance in the thin layer seawater micro-imaging analysis seawater, to having relatively high expectations of optical microphotograph imaging system.
Fig. 1 shows the machine under water of " the outstanding husky imager (ZL2005100131032) in the water " of suspended particulate substance in the measurement water of prior art.Outstanding husky imager is made up of machine and computing machine two parts waterborne under water in the water that Fig. 1 relates to, and the movement of machine is arranged in the cylindrical sleeves 1 under water, comprises microcobjective 3, CCD camera 2.The end cap outer setting sampling apparatus of machine cylindrical sleeves 1 under water, sampling apparatus comprise the stator 4 that is fixed on the end cap, the moving plate 5 in the stator outside, and moving plate 5 is transparent glass sheet with stator 4.Moving plate 5 is fixed on the front end of led light source device 6, and led light source device 6 is connected with the linear electric motors of the end cap outer setting of cylindrical sleeves 1.Under the drive of linear electric motors, moving plate 5 slides along stator 4, between moving plate 5 and stator 4, forms the thin layer water sample of gathering.Led light source illuminates water sample, and microcobjective 3 receives the image of the thin layer water sample that contains suspended particulate substance, and CCD camera 2 is converted into digital picture with the water sample image and passes to computing machine waterborne, handles the distribution and the concentration that obtain suspended particulate substance in the seawater sample then.
But, in the water shown in Figure 1 in the water of outstanding husky imager the microcobjective 3 of micro optical system to adopt enlargement ratios be 10 times short distance object lens, can not take considerable molecule below 5 microns in the seawater.For common short distance object lens; Take the molecule below 5 microns; The microcobjective enlargement ratio will reach 40 times at least; The microcobjective front end face need be less than 1 millimeter to the object distance between the particle that will observe, requires to be installed in object lens and is observed stator 4 between the particle less than 1 millimeter, and the stator 4 that plays the sealed window effect can't bear seawater pressure.In addition, the moving plate 5 of sampling apparatus is communicated with seawater with slit between the stator 4, has flowing seawater in the slit, and conditions of streaking appears in image that influence is taken easily, causes particle image fuzzy, is difficult to reflect really grain size.
Summary of the invention
Problem to suspended particulate substance measurement mechanism existence in the water of prior art; The present invention releases suspended particle imager in the high enlargement ratio water in new deep-sea; Adopt long apart from microcobjective; Increased the stator thickness between object lens and the moving plate, solved the withstand voltage contradiction with enlargement ratio in deep-sea, made the in-site measurement of the small suspended particle in deep-sea become possibility.Simultaneously, adopt auto-closing sampling mechanism, moving plate is arranged on movably on the seal closure, and the seal closure of automatic lifting is isolated from the outside the sampling seawater between moving plate and the stator, the photographic images fuzzy problem of avoiding marine stream to cause.
The suspended particle imager is become with computing machine two parts group waterborne
by machine under water in the high enlargement ratio water in deep-sea of the present invention.
Machine is a cylindrical structure under water; The movement of machine is arranged in the cylinder casing under water; Movement comprises long apart from microcobjective, digital eyepiece, microprocessor, battery case, and near the anterior end cap of casing, length is provided with digital eyepiece at the back apart from microcobjective to length apart from microcobjective.Cylinder casing front ends lid outer setting sampling apparatus, sampling apparatus is an auto-closing sampling mechanism, comprises elevating mechanism, led light source, stator, moving plate and ring seal cover.Stator is fixed on the outside of shell end cover; Moving plate be arranged on the bottom of led light source fixed cover uncovered on, led light source is fixed on the center of light source fixed cover, light source fixed cover arranged outside ring seal cover; The light source fixed cover is connected with elevating mechanism, and elevating mechanism drives the light source fixed cover and moves up and down.The action of elevating mechanism is by the control circuit control of microprocessor.
Suspended particle imager in the high enlargement ratio water in deep-sea involved in the present invention; Adopt long apart from microcobjective; Increase the stator thickness between object lens and the moving plate, solved the withstand voltage contradiction with enlargement ratio in deep-sea, can take deep-sea suspension molecule in the water below 5 microns; Adopt auto-closing sampling mechanism, moving plate is arranged on movably on the seal closure, and the seal closure moving plate of automatic lifting and the sampling seawater between the stator are isolated from the outside, the photographic images fuzzy problem of avoiding marine stream to cause.
