The quantitative aseptic sampling method for pipe dirt is that the distance L of a bucket of the quantitative aseptic sampling device for pipe dirt on pipe walls for eradicating the dirt is multiplied by the width R of the bucket, L*R is equal to S, and thereby, the sampling areas of the pipe walls can be obtained; the dirt quantity of unit area can be obtained from that the dirt weight of the bucket is divided by the sampling area S of the pipe walls to achieve the dirt quantitative sampling aim. The present invention has the advantages that (1) the quantification of the area of the collected pipe walls is carried out by the combination of electronic control technology and mechanical technology, and therefore, the quantitative sampling for the pipe wall sampling is realized; (2) the adoption of disposable parts ensures the sterility of a sampler, which makes samples difficult to be polluted and joined by other objects during the sample sampling process.
Description
Technical field
The present invention relates to sampling apparatus and method thereof, relate in particular to a kind of quantitative aseptic sampling device for pipe scale and method thereof.
Background technology
Along with Chinese economic development, people improve day by day for the requirement of quality of the life because people's life and work rhythm accelerates day by day, when more and more being particular about for the requirement of live and work, to live, working environment to improve cry also more and more higher.Owing to air-conditioning system can not in time be cleaned the air pollution that causes and also more and more caused people's great attention, because this is directly connected to we and household's physical and mental health.
Air-conditioning system especially suitable temperature, the humidity in the air-line system is the desirable place that bacterium, virus are grown and multiplied.According to expert statistics, the objectionable impurities that is present in the airduct comprises: dust, virus, fungi, mould, harmful bacteria, carbon element, various microorganism and insect corpse and pollen etc.They are the arch-criminals that cause room air pollution.
According to statistics, in more than 400 ten thousand commercial buildings of the U.S., have near three one-tenth be faced with serious air quality problems.
The Britain expert finds that eighth office room air is defective when 500 offices of investigation Britain, make employees problems such as chronic fatigue, pachylosis occur.
According to another Environmental Protection Administration of the Hong Kong Special Administrative Region selective examination statistics, there is 37.5% office building air quality exceed standard in Hong Kong.
NUS has the mansion of 3 to 15 years age of the buildings to detect to 5, finds that the bacteria content in some place exceeds 2 times than safety standard in 5 mansions, and in addition, the content of the yeast of same place, mould and carbon dioxide all is higher than safety standard.426 people that work in these 5 mansions are invited to accept physical examination, and the result shows that their great majority have serious " ill building syndrome " sign.
Central air conditioner system is being dominated the air metabolism of modern building, is the genuine core organ of buildings---lung ".
The survey showed that at US and European in mechanism such as EPA, Technical University Of Denmark, air conditioner ventilating system is owing to long-time running, cleaning reason such as improper, room air pollution comes from the 42%--53% that accounts for of air conditioner ventilating system, and major pollutants are particle and microorganism in the ventilating system.
The ventilating system of central air conditioner is the corner or spot as yet untouched by a clean-up campaign that long-term accumulation is got off, and its area is far longer than the unit area that we can clean at ordinary times.The airduct that can not get for a long time cleaning provides stable environment for objectionable impurities, they can constantly grow and along with the airduct that extends in all direction in indoor wide-scale distribution, cause air secondary to pollute in air-conditioning inside.Present most of central air conditioner generally uses low efficient filter, they at most can only filtered air in 40% pellet, pellet over half can enter central air conditioner system.On the one hand, these pellets might become the carrier of virus, virus is flowed in air conditioning wind pipe propagate, and therefore produce cross-infection.On the other hand, the pellet that particle is little interconnects becomes big dust, is accumulated in the bottom and the turning of air-line system, and they accumulate over a long period and have just grown microorganism.
These viruses and the microorganism that may exist in the air-line system are sent to everywhere indoor under the effect of blower fan, even more serious is that these contaminated air might be sucked back air-line system by air return system, through discharging once more after the simple process, objectively concentrated harmful gas and material, make IAQ (indoor air quality) pollution level than outdoor serious 2-5 doubly.
Learn with dust, dirt sample that microscopic analysis is gathered in the central air conditioner ventilating system, its Main Ingredients and Appearance is that dust grit, charcoal class material, crystalline solid, fiber, paint chips, fungi, viral micro-organisms and corrosion are dropped (See Figures) such as airduct inner-wall materials, also has the corpse of some insects to be mingled in wherein in addition.In case when being attached with microorganisms such as bacterium, fungi, yeast in the middle of the dust, also just be easy to make the people suffer from allergy or respiratory disease.
Except ventilating duct, as gas piping, natural gas line, all there is the cleaning problem in various conveyance conduits such as pipeline, and chemical industry from the beginning, power plant etc., and needing to clean just to have needs to detect.The present invention uses for this reason.
Detecting for airduct is example, requires to accomplish detection by quantitative, and most critical is to accomplish on the tube wall to gather dust on the wall of regulation here,

Embodiment
Because soil conditions has nothing in common with each other in the pipeline, powdery dust is arranged, have caked, glutinousness material etc. is also arranged, we adopt the bucker-type sampling method, and in order to guarantee to realize stipulating the sampling of area, we rely on the method for robot ambulation predetermined distance to reach for this reason.When just needing to sample, scoop is put down, touch the tube wall face, rely on robot ambulation to realize that scoop travels forward then and reach the purpose of sample thief, if we can determine the robot ambulation distance L, measure scoop effective width R, then L*.R=M.M is exactly a sampling area.
In order to guarantee that sampling process is not subjected to other pollutions, we have adopted two measures, 1) the scraper bowl separated into two parts, the one, link together with robot, we claim that it is a constant part, another part is the part that contacts with the dirt that is sampled, we adopt disposable part, every once sampling is changed disposable scraper bowl, can avoid impurity and germ etc. to be blended in the sample like this.2) after sample had been adopted by robot, cover lid at once made sample in the enclosure space that scraper bowl and lid are formed.Can avoid like this withdrawing from and have the thing of other foreign material or disease carrying germ to enter in the sample in the process, and guarantee in operating process, the sampling error that the loss of sample causes in the scraper bowl can not occur in robot.
For the dirt of powdery, not thorough at the dirt of shovel powdery for remedying scoop, we are provided with wiping block wiping pipeline wall in the scoop bottom.Being added on the sample again in the dirt amount that is increased on the cloth.Remedy the deficiency of scoop, improve the levels of precision of sampling.
As shown in the figure, quantitative aseptic sampling device for pipe scale has the sampling apparatus body, the device body front end is provided with first motor 1, first reduction gearing 2, scraper bowl connector 4, scraper bowl 5, scraper bowl is connected on the scraper bowl connector, motor passes through reduction gearing, the scraper bowl connector drives scraper bowl and moves up and down, scraper bowl 5 tops are provided with lid 6, be provided with spring 8 between scraper bowl and the lid, scraper bowl front end both sides are provided with little prominent bar 7, both sides, sampling apparatus body below respectively are provided with the crawler type motion, the crawler type walking mechanism has driving wheel 10, second motor 11, second reduction gearing 12, code-disc 13, engaged wheel 14, crawler belt 15, second motor drives driving wheel by second reduction gearing and rotates, and drives crawler belt promotion scraper bowl and advances, and code-disc sends the signal that driving wheel turns over angle.Described scraper bowl 5 is disposable scraper bowl.Scraper bowl 5 bottoms are provided with wiping block 9.
Lid on the scraper bowl is can cover automatically behind the shovel sample thief.This method can have a lot.Fig. 3 is one of them example.Two little prominent bars 7 are arranged on the lid both sides.When the motor rotation made scraper bowl 5 press close to the pipeline wall, scraper bowl lid 6 (see figure 3)s were owing to there is little prominent bar 7 can not make lid 6 press close to wall.Thereby reach lid is opened, when scraper bowl sampling end, motor 1 upwards rotates scraper bowl.Lid relies on spring 8 tightly to cover on scraper bowl.
Electrical system is conventional DC MOTOR CONTROL. it can be opened, the motivation that has a power failure, and also can export positive and negative voltage, makes the motor forward and backward.It accepts computer instruction, regulates motor rotation speed.
In order to measure and control the angle that motor turns over, so on reduction gearbox output shaft, also load onto code-disc 13 (see figure 1)s, the angle that reduction gearbox output shaft turns over can be sent the pulse signal number by code-disc and reflect, we only need counting pulse signal, just can know that reduction gearbox output shaft turns over angle.Fig. 5 represents this information feedback process.The 13rd, code-disc, 17 impulse meters, the 18th, computing machine.Code-disc has been arranged, and we just can know that driving wheel 10 (Fig. 1) turns over angle, also just can know the distance that robot advances, and we suppose that travel distance is L.After knowing L, we come to determine the effective width R of scraper bowl again, R determine can with experimental technique also can the actual measurement scraper bowl method come fixed.L and R have been arranged, and we just can obtain sampling area S=L*R.
For the accuracy of powdery dirt for guaranteeing that scraper bowl is sampled, we have increase wiping block (also available other energy wipings adsorb the material of dust) 9 (see figure 3)s under scraper bowl, scraper bowl shoveled wall also can stay some dust eventually, and it is just cleaner to nuzzle up through wiping block 9 again.When samples weighing, need only the wiping block and the dust of being with have been weighed exactly together.So just remedied the deficiency of scraper bowl.
More than explanation all is to be example with air channel dust, and it can be used for other pipelines in fact, as gas piping, and natural gas line, the conveyance conduit in power plant, chemical plant.No matter be gas, fluid pipeline.What need detection can both use said method.
Only be applicable to horizontal pipe in the above description,, can use equally as long as change robot form for vertical pipe.
