Description
Technical field
The utility model relates to a kind of deep-sea mechanism, specifically is meant a kind of sampling unit that is used for Deep-Sea Microorganisms.
Technical background
For the research of seabed microorganism, the most frequently used method is still fetched sample from the seabed and is studied to scientific surveying ship.Concentrate the sample mode of sampling, utilize the suction of equipment and filter design to make seawater enter sampler exactly and sample, promptly belong to initiatively sampling.
Seabed microorganism sampler generally is the single-stage filtering system at present, and the microbiological specimens impurity of obtaining is more, and research and analysis are produced a very large impact, and therefore is necessary to adopt multistage membrane filtration system.
The pump that the volume-variation of utilizing plunger plunger hole in the to-and-fro movement parallel with transmission shaft to be produced is carried out work is called ram pump, compares with other pumps, and the advantage that ram pump has has: the volumetric efficiency height, running steadily, discharge uniformity is good, and noise is low, the operating pressure height.In the sampling by filtration of Deep-Sea Microorganisms, the hole of filtering membrane is very little, needs bigger filtration pressure difference, and Deep-Sea Microorganisms concentration is very low in addition, often need to filter the amount that the more water yield just can be obtained needs, so flow is definite very important to studying its concentration.These can be resolved by ram pump.
Adopt the transistor commutating circuit to replace the motor of brush and reverser to be called dc brushless motor.Dc brushless motor is compared the common electric machine advantage to be had: the rotating speed variable range is big, and the motor speed of enclosed control is stable, is subjected to load effect very little.
Sampler is transferred to after the deep-sea with framework; the collection head suction pipe need be reached framework samples outward; and in transferring process in order to protect the collection head suction pipe, be with in the collection head suction pipe income framework, therefore the design collection head that can stretch also is necessary for the deep earth sampling device.
After sampling finishes, the gastight sampling tube can be put forward back sea level with framework under the effect of hawser, and in the process of this rising, the pressure of pressurize tube outside is in continuous reduction, every rising 100m then can fall 1MPa, final after the pressurize tube is mentioned sea level, the pressure of pressurize tube outside reduces to zero, but its inside has still kept the original position pressure of sampling spot.The pressurize cylindrical shell because recoverable deformation produces volumetric expansion, is added the distortion of other elastomericss (as sealing member etc.) in the effect meeting of interior pressure, and system is difficult to reach the pressurize effect of expection, therefore also needs to realize half initiatively pressurize by the pressure boost compensation system.
Deep-Sea Microorganisms living environment pressure is very high, and the sample that sampling obtains will remain under the highly compressed environment, otherwise will be because of decompression death, and how to shift microorganism under the highly compressed condition also is a problem of comparison difficulty in follow-up cultivation or other equipment.
