Description
Technical field
The utility model relates to the monitoring water environment technical field, and specifically, the utility model relates to a kind of water body buoy section sampling apparatus.
Background technology
Physics, chemistry, the biotic factor of the different water layers of the water bodys such as ocean, lake, reservoir, river are widely different, and traditional monitering buoy is general only monitors for surface water, can not truly reflect the water quality situation of whole water body section.For example, in the ocean, phytoplankton can be in the whole euphotic layer existence of degree of depth 0-200m, and the Phytoplankton biomass of so only measuring surface water is to represent Phytoplankton biomass in the whole 200m water column.
In order to carry out long term monitoring to the water body of different depth, the researchist has designed several different methods and device is done profile survey, substantially can be divided into four classes:
(1) the buoy section method of movement.The buoy integral body of carrying surveying instrument is carried out the section motion in water body inside, simultaneously the water body of different depth is monitored.Most typical representative is the Argos drifting buoy, by regulating up and down section motion in the marine site of buoyancy in degree of depth 2000m, measures the indexs such as water temperature, pressure, salinity, and carry out satellite communication when buoy surfaces.China scientific research personnel also autonomous Design some can do the buoy of section motion, such as Chinese invention patent CN 100445164C, CN 101738179B and CN 102129089A etc.
Although these buoys can carry out good profile survey, but all exist power supply supply difficulty, electric weight to exhaust the problem of necessary power cut-off, simultaneously can only measure the basic indexs such as water temperature, pressure, salinity, complicated nutritive salt and biological indicator can't be measured owing to length consuming time.
(2) the sensor section method of movement.Setting winch system on buoy or platform does the section motion by winch control sensor and measures in the underwater.Just proposed this viewpoint as far back as U.S.'s patent of invention 4157657 in 1979, the water quality vertical section automatic monitoring system of U.S. YSI Inc. has also adopted similar approach.The major defect of this method also is to measure complicated nutritive salt and biological indicator.U.S. Patent application US2003/0092393A1 has proposed a kind of platform that can regulate buoyancy that drags under buoy, carry instrument on the platform, by the lifting method of carrying out profile survey of control platform.The elevating control of platform is similar to the Argos drifting buoy in this method, but the sun power of water surface float is adopted in its power supply, can continue.For the instrument type of carrying on the platform, this patent is not pointed out in detail.
(3) the sensor section lays method.Wirerope of drag and drop under buoy or platform is installed water quality sensor every a segment distance on wirerope, be placed in the water body for a long time and monitor.Typical Representative is the temperature chain T-Chain system of U.S. PME company, and Chinese utility model patent CN 201497507U, CN 201215902U and CN2400792Y etc. have also proposed similar temperature catenary system.This system also take indexs such as simple gaging pressure, temperature as main, can't measure for nutritive salt and biological indicator.
(4) the sampling pipe section method of movement.Chinese invention patent application CN 102381441A has proposed a kind of sampling pipe VTOL (vertical take off and landing) below the motor control buoy and has come section sampling, and the instrument room that sample delivery enters buoy inside is carried out the method for analysis to measure.The advantage of this method is water sample is conveyed in the instrument room of buoy inside can carry out complicated measurement, such as the flow cytometry that utilizes that this patent proposes phytoplankton is counted, shortcoming is that sampling pipe easily with the current drift, causes the degree of depth that can't accurately determine the source water sample.
To sum up, still there is not a kind of preferably method that the water body section is carried out perfect physics, chemistry and biology measurement at present.Buoy and the sensor section method of movement are not suitable for carrying out process complexity, long nutritive salt consuming time, the measurement of biological indicator; The sensor section lays method can only measure simple physical index, if nutritive salt analysis, bio-analysis instrument also section are laid, cost is too high; The impact that the sampling pipe section method of movement is subject to drift about.More feasible mode is a kind of device that can carry out accurate section sampling under buoy of desired design at present, water sample is conveyed in the instrument cabin of buoy inside, utilize various advanced persons' physics, chemistry and biology analytical instrument to carry out perfect measurement, and provide electric power by the buoy solar electric power supply system, reach the purpose of unmanned, long-term, continuous monitoring.
