Description
Technical field
It is the utility model relates to a kind of water quality monitoring technical products field, in particular to a kind of based on the novel of paper tape instruction
Simple portable transparency measuring device.
Background technique
In recent years, the cities and towns black and odorous water phenomenon of domestic various regions is prominent, seriously restricts mentioning for people's living standard
It rises.House has put into effect " city black and odorous water renovation guide " in August, 2015 with town and country construction portion thus, by ammonia nitrogen, thoroughly
Totally four indexs are classified as the important evidence that black and odorous water determines for lightness, dissolved oxygen and oxidation-reduction potential.The guide specification, water body
To be slight black smelly when transparency is between 25-10cm, can determine that if being less than 10cm for severe it is black smelly, and by black and white disk method (Sai Shi
Disk method) or font method be classified as the standard method of situ measurement.According to the actual situation it is found that the application range of Sai Shi disk method most
It is extensive.
The transparence value usually assert refers to that black and white disk (Sai Shi disk) sinks down into the water surface or less and just disappears in tester
The vertical range when visual field, between the water surface and disk.Currently, people are to transparency measuring technology and product based on Sai Shi disk method
Expectation, be desirable to that its measurement is accurate, and operation is simple, and portable, cheap is applied widely.However, in water such as black-odor riverway improvement
Water Environmental Synthesis Dredge field in actual use, it is found that technical products involved by tradition Sai Shi disk method often have following 2 class
Obvious problem:
Problem 1: use scope is limited.It is limited by river two sides actual landform and space enrironment, such as works as water analysis
Point is arranged at the crossing bridge in certain river, but enclosure wall has been built at bridge both ends or there are the barrier construction such as architecture against regulations to build
Object or Channel slope are extremely precipitous, and gauger's work safety is unable to get guarantee, or are that Channel slope is extremely slow, river bank
The depth of water is extremely shallow at measuring point, and Sai Shi disk, which easily bottoms out, leads to not measure true transparency, and suchlike actual conditions generally require
Tester station can just carry out the measurement operation of transparency on higher bridge floor or higher river barricade, and need overlook view,
Such issues that often met in practical work process.Under such operating condition, farther out and the difference of tester's eyesight due to distance
Different, tester is difficult to see and judge the crosspoint (abbreviation A point) of the water surface and black and white flake down rope, and day colour cast is especially bright when dark
It is aobvious.Even if seeing A point, the removal process of black and white disk also easily makes tester forget the specific location of A point, so that the tool of A point
Body position vagueness in memory.Final test person can only be by general memory to A point, after the recycling disembarkation of black and white disk, then with survey
Amount tool, which measures or estimates reading, obtains transparency data.Therefore test value it is subjective, the precision of final transparence value also compared with
Low (such as estimate readings and be denoted as 10-15cm, 20cm etc.), can not obtain high-precision transparence value (such as obtain measured value be 11cm,
17cm etc.).
2: Sai Shi disk of problem is easy to damage, and Sai Shi disk easily drifts about when water flow is very fast, and binding rope easily tilts.Conventional Sai Shi disk product
Majority is made of plastic material, is easily collided in transport use process broken, such as plastics black and white disk is in removal process,
It easily collides and damages with bridge, concrete guard wall, applicant has purchased multiple plastic material black and white disks, but uses the longevity
Life is not grown.Furthermore, during actual use, if river water flow velocity is higher, traditional rope hangs the technology production for tying up Sai Shi disk
Product easily generate offset with water flow, to interfere the normal reading of transparence value, measured value are made to deviate actual value.
In view of the above-mentioned problems, transparency measuring technology and product that tester needs modified version to be to overcome drawbacks described above,
To obtain accurately satisfied transparence value.With regard to the above-mentioned measurement problem through being commonly encountered, studies in China person proposes more solution
Certainly gimmick.For problem 2, existing a large amount of simple portable innovation and creation achievements can be solved preferably.But it is directed to problem 1,
At present Simple portable and can solve problem technical solution and product still lack.The present invention intends bringing forward the technology for solving the problems, such as 1
Scheme and corresponding product, invention product need to have both the effect of overcoming the problems, such as 2.By the investigation of documents and materials, for above-mentioned 2 class
Using problem, patent application document plans numerous domestic inventor and improves gimmick and proposition to the typical of traditional Sai Shi disk method
Representative art product, carry out short summary be summarized as follows:
For problem 1, existing technical solution can be divided into following two major classes:
(1) optical method: national inventing patent (105223167 A of application publication number CN) is proposed by " hollow cylinder+black and white
The transparency test device of disk+photoinduction transmitting and receiving element+control device+display device "；National inventing patent (Shen
Please 106053395 A of publication No. CN), underwater light intensity is measured using photosensitive sensor, shoots Sai Shi disk using capture apparatus, with
The folding and unfolding of this control hoist engine connecting line, to obtain water transparency value；National inventing patent (application publication number CN
107084931 A) and china national practical new-type patent (206671177 U of Authorization Notice No. CN) also use similar principle.It is this kind of
Method can effectively overcome the above problem 1, reduce remote artificial reading and the bad caused artificial subjective error of observation angle,
It even can directly show the reading of transparence value, but there are at high cost, prices, easy to damage, maintenance for such technology and products thereof
The problems such as at high cost.
(2) labelling method: i.e. when Sai Shi disk, which is sunk down into, just disappears in the visual field, using special method by the water surface at this time
Boundary position between rope is recorded, and then reads transparence value after recycling disembarkation.Include:
A. color mark method: china national practical new-type patent (Authorization Notice No. CN207318353U) proposes on Sai Shi disk
Several color pearls of different colours, the distance being kept fixed between color pearl, in Sai Shi disk are fixedly installed on the binding measurement rope of side
Sinking watching in, transparence value with the position of corresponding color pearl is judged by the observation water surface, the program is simply portable, measurement accuracy
When can reach a centimetre rank, but aloft measuring, the extremely difficult color for seeing color pearl of tester or position cause measurement error to increase
It greatly or is unable to measure, and the patent aims at the test of shallow water cultivating pool transparency and designs, therefore is unsuitable for 1 institute of the above problem
The working condition measurement condition stated.
B. position mark method: china national practical new-type patent (Authorization Notice No. CN206300891 U) is proposed in Sai Shi disk
Limited block is fixedly installed on the binding drawstring of top, the intermediate floating plate perforated in tandem on aforementioned drawstring is installed on floating plate
There is locking device (function is realized by sliding shoe).Sai Shi disk and its lash rope can smoothly be transported downwards relative to floating plate
It is dynamic, but after Sai Shi disk sinks down under water and just disappears in the visual field, pull-up Sai Shi disk need to be recycled, floating plate is then stuck at this time
On the limited block of rising.Based on the principle, by measuring the distance between floating plate present position and plummet, it is accurate to obtain
Water transparency value.The program is relatively simple with respect to preceding method, and feasibility is high.But there are still limits for the solution
Block deformation (if plastics) easy to wear, limited block is more difficult to be fixed on drawstring for a long time, integrated " drawstring+limited block " accessory and
The problem of " floating plate+attached locking device " accessory processing and fabricating complexity and higher cost, there is also work as waters floating material impurity
Floating plate is easier to stuck lead to problems such as system that can not work when more.National inventing patent (application publication number CN
107884532 A) similar locking principle measurement transparency is also taken, which will " indicating sleeve+vertical guide sleeve+elasticity spine
The locking system that rack gear+ring limit block " is constituted is arranged on the scaffold for flying at the water surface, and china national practical new-type patent (is awarded
Weigh notification number CN206300891 U) then by the locking system setting at floating plate on binding drawstring.Therefore the principle of two patents
It is more similar, it is existing also more similar with limitation using problem, only had differences on realizing gimmick；In addition, there is test
Person attempts to determine distance of the Sai Shi disk disk apart from the water surface by the water stain position of drawstring above Guan Chasaishi disk, it follows that
Transparence value, but user would generally in a short time to many places water body carry out transparency continuous monitoring, it is water stain can not timely wind
It is dry therefore this method is infeasible in actual operation, because repeatedly water stain can be overlapped so leading to not to determine water stain when time measurement
Specific location.
C. graduated scale notation: china national practical new-type patent (204882363 U of Authorization Notice No. CN) has used for reference fishing rod
The thinking for recycling setline installs rope rolling apparatus on mobile jib and counter passes through counter in the removal process of Sai Shi disk
Metering obtains transparence value, and the method measurement accuracy is high, but painstaking there may be operating, and rope folding and unfolding is difficult, and mobile jib is easily lost
Problem.China national practical new-type patent (202994775 U of Authorization Notice No. CN) use replaces on Sai Shi disk with graduated meter ruler
The rope of side, to read transparence value, but the method is since meter ruler is usually in that flat strip shaped easily leads to the inclination of Sai Shi disk, and tester
It stands when on higher bridge floor or embankment, it is farther out and the influence of eyesight difference due to distance, usually more ugly to understand meter ruler
Shown in accurate transparence value, therefore application range is limited.
For problem 2, to solve the problems, such as the easy to damage of Sai Shi disk, the approach of Sai Shi disk can be made by using metal material
It is resolved, as china national practical new-type patent (203259475 U of Authorization Notice No. CN) makes Sai Shi using round stainless steel plate
Disk, thickness reach 6-7mm.To solve the problem of that the Sai Shi disk binding rope that easily drifts about easily tilts, presently, there are following major technique solution party
Case:
A. heavy pendant weight is increased: such as china national practical new-type patent (203259475 U of Authorization Notice No. CN, Granted publication
Number 206057169 U of CN 204789332 U, Authorization Notice No. CN), water is resisted by the method for aggravating heavy pendant or weight linear meter
Stream washes away, and the realization difficulty of the method is lower.
B. improve system stiffness method: china national practical new-type patent (204594878 U of Authorization Notice No. CN) is in Sai Shi disk
The more piece hollow tube casing of suit is provided with outside connection steel wire, to improve system stiffness, the realization difficulty of the method is lower；It is national real
With the measurement structure of new patent (205067343 U of Authorization Notice No. CN) then in the higher hollow cylinder of rigidity, therefore can
Effectively keep the plumbness of test macro and the water surface.
C. similar polygon method: national inventing patent (Authorization Notice No. CN103398986 B) and national utility model are special
The inventor of sharp (203385664 U of Authorization Notice No. CN) passes through partial parameters using the characteristic principle of similar polygon
Water-outlet body actual transparency angle value is converted in measurement again, but the operation of the method realizes that process is cumbersome.
D. sensor method: the inventor of national inventing patent (Authorization Notice No. CN105004699B) passes through setting hydraulic pressure
Sensor, gravimetric tilt sensors and calculator can accurately calculate transparence value by specific formula, but the method is to measurement
Facility it is mating more demanding, cost is higher, and daily maintenance is more demanding, is not easy to promote the use of.
In general, many years according to applicant in China East China test experience, it is saturating to estimate water body before official testing
Lightness, 4 classes of operating condition point of usual water transparency test, preceding 3 class is more common in Urban Water Environment comprehensive improvement project, most
The application scenarios of 1 class are less afterwards, and details are as follows: (1) low transparency operating condition: 60 cm of water transparency <.Usual completed region of the city
River, pond in range, the transparence value of especially black and odorous water is lower, often below 60cm, mainly due to water body by
To cities and towns industry, the pollution of sanitary sewage, and the suspension contents such as algae and water are excessively high caused.(2) medium transparency operating condition: water
Body transparency is between 60-120 cm.River, lake, reservoir and the pond in cities and towns countryside are tended to occur at, this kind of water body may be led
Will be by agricultural area source pollutants or soil erosion pollutant effects, the content of water body nitrogen phosphorus or silt is moderate, and water body presents rich
Nutrient laden or pollution by silt cause in water body containing algae or silt suspended matter as main component, water transparency
It is not high；(3) high grade of transparency operating condition: water transparency is between 120 cm-180cm.Tend to occur at the light clean water of pollution level
Library, lake, and existence have the waters of more water plant, such waters algae density is low, and sediment content is low, therefore transparency is higher；
(4) ultra-high transparency operating condition: water transparency is higher than 180cm.Tend to occur at unfrequented mountain area cleaning reservoir, lake,
Pond or water plant cleaning waters in great numbers, this kind of natural water area often do not need to administer, therefore its transparency is comprehensive in water environment
It seldom monitors, therefore is not included in this patent limit of consideration in regulation project, the transparence value of such water body is directly expressed as " >
180cm ".
