Abstract
The present invention relates to a high pressure injector which is arranged on a deep sea testing platform. The high pressure injector comprises a driving connecting device composed of a thick piston cylinder and a thin piston cylinder which are communicated by a guide tube, wherein quantitative air which is balanced with the outside is sealed between two pistons of the connecting device; at least one injector is bound beside the thin piston cylinder, a proper distance is formed between the tail end of a piston rod of the injector filled with quantitative reagents and the tail end of a piston rod of the thin piston cylinder, and the quantitative reagents filled in the injector are dynamically injected into a reagent bottle to be tested from the injection port of the bound injector by an injection catheter under the pushing of a wing handle at the tail end of the piston rod of the thin piston cylinder. The present invention can provide dynamic force with the change of pressure, and is particularly suitable for the application of the change of reagent concentration. The high pressure injector can quantitatively, stably and reliably provide the dynamic force to inject testing objects, such as a reagent, etc. to the reagent bottle under high-pressure environment for achieving the purpose of changing the reagent concentration, and used materials can not pollute the 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
Slightly/ V
Carefully=1.01-10000.
The invention has the advantages that: this high-pressure injection device is because in thick, the driving linker that the small piston cylinder constitutes that is communicated with by conduit, promptly seal quantitative and air extraneous balance between the two-piston of this linker up for safekeeping, because the connection of conduit, make that the gas in the cavity of heavy manual labour piston cylinder can be pressed in the small piston cylinder cavity.If thin cylinder is respectively 10ml, 1000ml with the volume of thick cylinder.When outside pressure increased, if the friction force of piston and piston cylinder and load during greater than pressure, then two-piston was not move; Pressure when the external world continues to increase, experiment confirm, when if the friction factor of two-piston and piston cylinder is more or less the same, heavy manual labour is beyond the Great Wall because the pressure of the big generation of sectional area is big than the pressure on the small piston, both friction force then is more or less the same, when the outside pressure increase, the heavy manual labour plug can at first move to cylinder inner cavity, up to reaching pressure equilibrium.When the heavy manual labour plug moves to the end, at this moment, can not move because the heavy manual labour plug is subjected to the restriction of cylinder, small piston is ability setting in motion under the effect of hyperbaric environment at this moment.When the heavy manual labour plug is pressed into all gas in its cylinder cavity in the small piston cylinder, by The Ideal-Gas Equation PV/T=C as can be known: this moment, the pressure of small piston cylinder was (1000+10)/10=101 (crust), i.e. 10.1MPa.If this moment, the length of small piston cylinder cavity was L, i.e. original state.When pressure raises to 20MPa (pressure that is equivalent to 2000 meters depth of water places), this moment, the length of small piston cylinder cavity was about L/2, i.e. the displacement of small piston is L-L/2=L/2.This moment, the small piston displacement was bigger, can inject more testing liquid, was convenient to control the concentration of testing liquid.Driving linker 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 material.
