Description
Technical field
This utility model relates to water analysis facility technology field, particularly to a kind of measuring instrument for measuring water transparency.
Background technology
During present stage field water is measured, transparency index obtains by traditional transparent plate often, black and white disk or colored disk will be tied down by tape measure, and sends in water, until till eyes invisible black and white disk or colored disk, read what the scale on tape measure completed.
But, this method is in actual field operation, and error is relatively big, and particularly in boisterous weather environment, tape measure the transparent plate tied down can occur position to offset under the effect of current, and on tape measure, the numerical value of actual read-out is also the most inaccurate.
Therefore, how to solve water transparency in prior art and measure inaccurate problem, become those skilled in the art's important technological problems to be solved.
Summary of the invention
This utility model provides a kind of measuring instrument for measuring water transparency, uses this measuring instrument to carry out the measurement of water transparency, has higher accuracy.
The measuring instrument for measuring water transparency that this utility model provides, including:
Disk, described disc centre is provided with the first hydraulic pressure sensor;
It is connected to the wire of described first hydraulic pressure sensor;
It is connected to described wire and the second hydraulic pressure sensor of the existence distance with described first hydraulic pressure sensor;
Gravimetric tilt sensors for sensor wire angle of inclination;
Computer, is the most communicably connected with described gravimetric tilt sensors, the first hydraulic pressure sensor and the second hydraulic pressure sensor.
Preferably, described gravimetric tilt sensors is connected on described second hydraulic pressure sensor.
Preferably, the center of described disk is provided with gravity block.
Preferably, the coiling apparatus for winding described wire is also included.
Preferably, described computer includes the display screen of the water transparency value recorded for display.
Preferably, described disk is colored disk.
When the measuring instrument using this utility model to provide carries out water transparency measurement, first disk is put in water body, till eyes can't see disk.It should be noted that, after disk is put in water body, the degree of depth of the present position of the first hydraulic pressure sensor is more than the second hydraulic pressure sensor present position, the pressure that first hydraulic pressure sensor senses is P1, the pressure that second hydraulic pressure sensor senses is P2, distance between first hydraulic pressure sensor and the second hydraulic pressure sensor is known as s, the wire angle of inclination that gravimetric tilt sensors senses is α, the pressure difference Δ P=P1-P2 of the second hydraulic pressure sensor and the first hydraulic pressure sensor present position, the depth difference Δ h=h1-h2=s cos α of the two present position, according to P1=ρ water gh1, P2=ρ water gh2, draw ρWater=Δ P/(cos α g s), therefore can draw transparency h1=P1/ (ρWaterG)=(P1 cos α g s)/(Δ P g), computer can calculate the transparency of water body according to this formula.Be arranged such, this utility model provide measuring instrument carry out water transparency measure time, the error caused because disk glances off can be avoided, measurement result has higher accuracy.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in describing below is only embodiments more of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is measuring instrument schematic diagram in this utility model detailed description of the invention;
In Fig. 1:
Disk 11, wire the 12, first hydraulic pressure sensor the 13, second hydraulic pressure sensor 15, coiling apparatus 16.
Detailed description of the invention
This detailed description of the invention provides a kind of measuring instrument for measuring water transparency, uses this measuring instrument to carry out the measurement of water transparency, has higher accuracy.
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Refer to Fig. 1, a kind of measuring instrument for measuring water transparency that this detailed description of the invention provides, including: disk the 11, first hydraulic pressure sensor 13, wire the 12, second hydraulic pressure sensor 15, gravimetric tilt inductive transducer (not shown) and computer.
Wherein, the first hydraulic pressure sensor 13 is arranged on disk 11 center, and fixing with the end of wire 12 is connected.Second hydraulic pressure sensor 15 is also fixing with wire 12 to be connected, and maintains a certain distance s with the first hydraulic pressure sensor 13, and this distance s can be 5-10cm.Gravimetric tilt sensors is for the tilt angle alpha of sensor wire 12.Computer is the most communicably connected with gravimetric tilt sensors, the first hydraulic pressure sensor 13 and the second hydraulic pressure sensor 15, in order to gathers hydraulic pressure data and wire 12 tilt data, and calculates water transparency.
When the measuring instrument using this detailed description of the invention to provide carries out water transparency measurement, first disk 11 is put in water body, till eyes can't see disk 11.It should be noted that, after disk 11 is put in water body, the degree of depth of the present position of the first hydraulic pressure sensor 13 is more than the second hydraulic pressure sensor 15 present position, the pressure that first hydraulic pressure sensor 13 senses is P1, the pressure that second hydraulic pressure sensor 15 senses is P2, distance between first hydraulic pressure sensor 13 and the second hydraulic pressure sensor 15 is known as s, wire 12 angle of inclination that gravimetric tilt sensors senses is α, second hydraulic pressure sensor 15 and the pressure difference Δ P=P1-P2 of the first hydraulic pressure sensor 13 present position, the depth difference Δ h=h1-h2=s cos α of the two present position, according to P1=ρ water gh1, P2=ρ water gh2, draw ρWater=Δ P/(cos α g s), therefore can draw transparency h1=P1/ (ρWaterG)=(P1 cos α g s)/(Δ P g), computer can calculate the transparency of water body according to this formula.
