Abstract

The utility model discloses a kind of transparency measuring device, include expansion link, black and white dish and safety buckle, black and white dish is fixed on the end of expansion link by described safety buckle.The utility model, by replacing traditional rope with expansion link, considerably reduces the impact that water volume flow rate, buoyancy and wind-force cause measurement result; And utilize set temperature meter and memory pressure meter on black and white dish, and utilize expansion link with a scale, reduce necessary mensuration number of times, improve the accuracy of data simultaneously, improve work efficiency on the whole.The utility model can be widely used in environmental monitoring field as a kind of transparency measuring device.

Description

A kind of transparency measuring device
Technical field
The utility model relates to environmental monitoring field, especially a kind of transparency measuring device.
Background technology
When carrying out activety fault monitoring, needing to investigate the transparency in water body, understanding water body clarification degree.At present, in the ecosystem, water transparency is by a rope connection black and white dish mensuration not with a scale.Rope does not have scale only rely on estimation post-tensioning to debark measured length again, often cause data inaccurate.On the other hand rope and black and white dish lighter, each mensuration is by flow velocity, wind-force and buoyancy effect, rope easy run-off the straight when the words that flow velocity, wind-force are too large measure, cause black and white dish vertical subsidence can not can produce angle difference impact mensuration accuracy, and black and white dish is gentlier by buoyancy effect not easily submerged, digital independent is simultaneously by eyesight difference and the subjective impact of each mensuration personnel, the different situation of each mensuration personnel reading may be produced, data accuracy is poor, often repeatedly will could measure and accurately make work efficiency lower.
Utility model content
In order to solve the problems of the technologies described above, the purpose of this utility model is: provide a kind of and realize transparency measuring device that is efficient, Accurate Measurement transparency.
The technical scheme that the utility model adopts is: a kind of transparency measuring device, and include expansion link, black and white dish and safety buckle, black and white dish is fixed on the end of expansion link by described safety buckle.
Further, the material of described expansion link is hard material.
Further, the bottom of described black and white dish also arranges safety hook in addition, and described safety hook is used for hook plummet.
Further, described black and white dish is also provided with thermometer and memory pressure meter.
Further, described expansion link is folding expansion link, and described folding expansion link includes handheld terminal and measuring junction.
Further, described handheld terminal is provided with the shaking tray that the measuring junction for controlling expansion link stretches.
Further, described shaking tray is also connected with handheld ring.
Further, the measuring junction of described expansion link is made up of the little bar of 50cm, with even scale on described little bar.
Further, described safety buckle is dismountable Double-protective safety button.
The beneficial effects of the utility model are: by replacing traditional rope with expansion link, considerably reduce the impact that water volume flow rate, buoyancy and wind-force cause measurement result; And utilize set temperature meter and memory pressure meter on black and white dish, and utilize expansion link with a scale, reduce necessary mensuration number of times, improve the accuracy of data simultaneously, improve work efficiency on the whole.
Accompanying drawing explanation
Fig. 1 is concrete structure figure of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
With reference to Fig. 1, a kind of transparency measuring device, includes expansion link 1, black and white dish 2 and safety buckle 3, and black and white dish 2 is fixed on the end of expansion link 1 by described safety buckle 3.
Be further used as preferred embodiment, the material of described expansion link 1 is hard material.
Use expansion link 1 but not black and white dish 2 more easily can be put into water by rope, and when measuring by the impact of the factors such as flow velocity wind-force, especially expansion link 1 is made up of hard material.
Be further used as preferred embodiment, the bottom of described black and white dish 2 also arranges safety hook in addition, and described safety hook is used for hook plummet.
The plummet that safety hook can be used for hook Different Weight is set in black and white dish 2 bottom, ensures the vertical subsidence of black and white dish 2, and further ensure black and white dish 2 not by the such environmental effects such as buoyancy, flow velocity, thus improve the accuracy of measurement result.
Be further used as preferred embodiment, described black and white dish 2 be also provided with thermometer and memory pressure meter.
Described thermometer is for measuring the temperature of water body, memory pressure meter can record pressure P under water, and then calculate the depth of water according to formula h=P/ ρ g, wherein ρ represents water body density, g represents local gravitational acceleration, accurately calculates the subjective and eyesight influence of individual when transparency data avoid mensuration by memory pressure meter.
Be further used as preferred embodiment, described expansion link 1 is folding expansion link, and described folding expansion link includes handheld terminal 11 and measuring junction 12.
Be further used as preferred embodiment, described handheld terminal 11 is provided with the shaking tray 4 that the measuring junction 12 for controlling expansion link stretches.
Be further used as preferred embodiment, described shaking tray 4 is also connected with handheld ring 5.
It is prevent from surveying timing lever landing on hand that described handheld ring 5 can hang over, and plays a protective role.
Be further used as preferred embodiment, the measuring junction 12 of described expansion link 1 is made up of the little bar of 50cm, with even scale on described little bar.
When black and white dish 2 is underwater and readable, especially saves time when needs repetitive measurement, increase work efficiency.
Be further used as preferred embodiment, described safety buckle 3 is dismountable Double-protective safety button.
Measure complete expansion link 1 can contraction, safety buckle 3 and black and white dish 2 are dismantled collection simultaneously, be easy to carry about with one.
More than that better enforcement of the present utility model is illustrated, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art can also make all equivalents or replacement under the prerequisite without prejudice to the utility model spirit, and these equivalent distortion or replacement are all included in the application's claim limited range.
