Abstract
The equipment includes driven connected vessels composed of thick piston cylinder and thin piston cylinder, which are connected through pipe. Quantitative air balanced to outside is sealed between two connected vessels. Bound at least one injector is near to the thin piston cylinder. There is proper distance between tail end of piston rod of injector with quantitative reagent being loaded and wing type handle at tail end of piston rod of thin piston cylinder. Under push pressure, quantitative reagent is injected to reagent bottle from the said injector to change concentration of reagent. The equipment supplies dynamic force as pressure changes, and used material does not cause pollution to reagent.
Description
(1) technical field
The present invention relates to a kind of hyperbaric environment lower sensor technology, it specifically is a kind of high-pressure injection device of the reagent bottle of under hyperbaric environment, dynamically annotating, this device can be under hyperbaric environment along with the variation of pressure, experiment reagent is provided, and it belongs to the oceanographic instrumentation detection technique field that deep-sea resources is surveyed project.
(2) background technology
Under deep-marine-environment, its pressure is huge, and general equipment and device can produce distortion under so high pressure, cause and damage or cisco unity malfunction.In the research that deep-sea resources is surveyed, study, heavy metal and other metals resources of detecting deep.This just be unable to do without the deep-sea analogue test platform.This platform often will provide the reagent of variable concentrations, comes the degree of accuracy and the response condition of detecting sensor.As, for detecting and proofread and correct the concentration that the deep-sea sensor will be measured metallic ion in the deep-sea.On the detection platform of deep-sea, will put into the testing liquid of the concentration known of preparation in advance for this reason, detect the data of deep-sea sensor under different pressures again.The difference of the test solution concentration of these data and concentration known is exactly the degree of accuracy of sensor.Detect and proofread and correct the response condition of this sensor to concentration change, be sensitivity, must under high pressure dynamically change the concentration of solution, the test solvent concentration that changes under so high pressure wherein is very difficult, and the concentration of deep-sea metallic ion is very low, if use metallic conduit transmission reagent, can pollute reagent, and the intensity of organic material can not satisfy the requirement of transmission reagent under the high pressure like this.Abroad someone's liquid chromatography pump of adopting chemical test equipment liquid chromatograph to use is played reagent by the titanium kapillary to the inside, and such scheme is very expensive.Under the hyperbaric environment of deep-sea, dynamically the special high-pressure injection device of filling trier does not appear in the newspapers always in reagent bottle.
(3) technology contents
The objective of the invention is to adapt under the hyperbaric environment of deep-sea, a kind of high-pressure injection device of the reagent bottle of dynamically annotating under hyperbaric environment is provided, this device can be quantitatively, stable, provide dynamically in reagent bottle trier such as filling reagent reliably, reach the purpose that changes reagent concentration, and the material that uses can not pollute to reagent.
Task of the present invention is finished by following technical scheme: develop a kind of high-pressure injection device, it is installed on the detection platform of deep-sea.This device includes: by thick, the driving linker that the small piston cylinder constitutes that conduit is communicated with, seal quantitative and air extraneous balance between the two-piston of this linker up for safekeeping; Be provided with at least one syringe in the binding of small piston cylinder next door, the piston rod tail end that this syringe of quantitative reagent is housed has suitable distance at a distance of the piston rod tail end wing handle of small piston cylinder, under the pushing of the piston rod tail end wing handle of small piston cylinder, dynamically the injection port from this syringe of binding injects the test agent bottle to the quantitative reagent that this syringe is equipped with by injection catheter.
Described this syringe that quantitative reagent is housed, its number that is bundled in small piston cylinder next door is that 1-20 props up, the piston rod tail end of all this syringes or be on the radial section, or be on the different radial sections that data demand is arranged.
Described this syringe that quantitative reagent is housed, its piston rod tail end at a distance of the suitable distance of the piston rod tail end wing handle of small piston cylinder is: 0---1000mm.
Described thick, small piston cylinder, wherein the volume V of heavy manual labour piston cylinder that is communicated with by conduit
SlightlyVolume V with the small piston cylinder
CarefullyBetween ratio V

As outside pressure P
2During increase, if the friction force of piston 13,3 and piston cylinder 11,1 and load during greater than pressure, then two-piston 13,3rd, do not move; Pressure P when the external world
2Continue to increase, experiment confirm is when the friction factor of two- piston 13,3 is identical with friction force, the pressure that produces on the heavy manual labour plug 13 is just big, because friction force and load are less than this pressure, this moment, then heavy manual labour plug 13 can at first move to heavy manual labour piston cylinder 11 inner chamber body 12, up to reaching pressure equilibrium.Experiment confirm: at this moment because heavy manual labour plug 13 is subjected to the restriction of heavy manual labour piston cylinder 11, can not move, small piston 3 is ability setting in motion under the effect of hyperbaric environment at this moment.When heavy manual labour plug 13 is pressed into all gas in its cylinder 11 cavitys 12 in the cavity 2 of small piston cylinder 1, as can be known: pressure P in this moment small piston cylinder 1 the cavity 2 by The Ideal-Gas Equation PV/T=C
1Be (1000+10)/10=101 (crust), i.e. 10.1MPa.If this moment, the length of small piston cylinder 1 cavity 2 was L, i.e. original state.Pressure P when the external world
2Rise when doubling to 20MPa (pressure that is equivalent to 2000 meters depth of water places), this moment, the length of small piston cylinder 1 cavity 2 was L/2, i.e. the displacement of small piston 3 is L-L/2=L/2.This moment, small piston 3 displacements were bigger, can inject more test reagent 5, were convenient to control the concentration of test reagent 5.Driving linker 11-1 of the present invention can provide power in the change along with pressure, is particularly suitable for changing the application of reagent concentration, promptly under hyperbaric environment dynamically to reagent bottle filling reagent material.
