Description

Liquid multi-layer sampling device

Technical field: the utility model relates to a kind of liquid sampler, particularly is applicable to a kind of multi-layer sampling device of water samplings such as ocean, lake, rivers and irrigation canals and ditches.

Background technology: fluid sample collection, particularly water sampling are to carry out water analysis, implement the important step of environment monitoring.According to national environmental protection portion water quality monitoring rule and water sample sampling request, should on three aspects in the upper, middle and lower of water body, obtain water sample, could the basic authenticity that reflects water quality.The water quality that Ministry of Water Resources of country also requires surface water and underground water to be carried out each different aspects is carried out water analysis, that is to say the multilayer water sample that needs to gather each different aspects.The water sample sampling apparatus of prior art generally all is fairly simple artificial or half manually-operated device, can only carry out the individual layer sampling, and can not carry out the multilayer sampling.When needs are gathered the multilayer water sample, just need repeatedly gather, its operation is cumbersome, and labour intensity is big, inefficiency.

Summary of the invention: the purpose of this utility model provides a kind of novel liquid sampler, in order to overcome the existing above-mentioned drawback of prior art sampling apparatus effectively.The utility model is to improve to realize on the basis of prior art sampling apparatus, it comprises the sampling head that the rope that twines on windlass, the lifting drum is connected with rope, the windlass that it is characterized in that it has a support, be fixed with back shaft on the support, be fixed with gear on the bolster, reel also is installed simultaneously.This reel is hollow reel, in be provided with motor and accumulator, electric machine main shaft is provided with gear, fixing gearing mesh on this gear and the above-mentioned said bolster; The end of reel is provided with the control micro computer; Also be provided with the sampling bottle stand on the support, the sampling bottle stand is provided with the branch bottle solenoid valve that has three outlets at least, divide the bottle solenoid valve below be equipped with at least three sampling bottles.Said sampling head has the housing of a tape guide wing, and water pump and liquid level, temperature signal sensor are housed in the housing.Said rope has a flexible protective pipe, is provided with messenger cable, power cable, pressure, temperature sensor signal cable, suction hose, pressure transducer air balance pipe in this protection tube.One end of said messenger cable is fixed on the reel, and the other end is connected with sampling head; One termination accumulator of power cable, the other end be through control micro computer water pump, by the startup of control microcomputerized control water pump with close; Liquid level, temperature sensor signal cable one end connect the control micro computer, and the other end is connected with liquid level, temperature signal sensor, and water level that is transmitted and temperature signal are presented on the LCD screen with digital form after control circuit is handled; One end of suction hose is connected with above-mentioned said branch bottle solenoid valve, and the other end connects water pump; One end of liquid level sensor air balance pipe is fixed on the reel, and the other end is connected with liquid level sensor.Accumulator is the power supply of motor, water pump, control micro computer, liquid level, temperature sensor.

During use, by the control micro computer, be provided with earlier according to sampling request.On needs are gathered, in, during following three layers of water sample, then set by micro computer, in, following three layers of water sample pattern, turn on the power switch then, electric motor starting, the reel rotation, the rope that is coiled on the reel is sent into sampling head under water, at this moment being contained in liquid level sensor on the sampling head is detecting always and is remembering water level depth, when water pump and liquid level sensor arrive the bottom, reel rotates some commentaries on classics again, the measured water level depth signal of pressure transducer no longer changes, then control micro computer and will confirm that this depth of water is the depth capacity of water body, instruct pump operation to gather lower floor's water sample simultaneously, water sample is sent the water surface by suction hose, flows in first sampling bottle by a minute bottle solenoid valve; After this, reel counter-rotating promotes water pump, and when the water signal that reacts up when liquid level sensor was 1/2nd water depths, reel stopped operating, and micro computer instruction pump operation is gathered the middle level water sample, delivers in second sampling bottle; After this reel is gone backward rotation again, and when the pressure signal that reacts up when pressure transducer demonstrated the depth of water and is 5-20 centimetre, reel stops operating, and was the same, gathers the upper strata water sample, delivers in the 3rd sampling bottle.When the multilayer water sample of certain depth is separated by in the needs collection, can be by the be separated by multilayer water sampling pattern of this certain depth of control micro computer setting, gather lower floor's water sample according to above-mentioned upper, middle and lower-ranking sampling routine earlier, reel counter-rotating then promotes sampling head, when showing sampling interval depth of water of lifting, reel then shuts down, control micro computer instruction pump working is sampled, and this water sample of collection is for counting second layer water sample down.Analogize later on constantly to up-sampling, when collecting that water level depth is not enough sets the interval sampling degree of depth, sampling head will directly be promoted to the upper strata, gather the upper strata water sample, so that finish multilayer sampling task.When needs are gathered the water sample of a certain degree of depth, then be provided with and gather this degree of depth water sample, turn on the power switch electric motor starting then, the reel rotation, the rope that is coiled on the reel is sent into sampling head under water, at this moment is contained in liquid level sensor on the sampling head and is detecting always and remember the depth of water, when water level depth reaches set depth, reel stops operating, micro computer instruction pump operation is gathered water sample, and water sample is sent the water surface by suction hose and arrived a branch bottle solenoid valve, flows in the sampling bottle.After sampling finished, reel reversed, and sampling head is left the water pack up, and then finished the sampling task of water body.

The utility model modern design, rational in infrastructure, compare with the prior art sampling apparatus, both can gather the individual layer water sample, can gather the multilayer water sample again, the robotization continued operation, easy and simple to handle, labour intensity is little, and high efficiency is time saving and energy saving.
