Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the invention, are given by way of illustration only.

Example 1

The embodiment discloses a novel water transparency measuring device, and as shown in fig. 2, the device comprises a graduated scale reel, a handle for holding hands, symmetrical protractor sectors, a handle for controlling the length of the graduated scale to swing, the graduated scale and a Samsung disc with the diameter of 20cm (as shown in fig. 1). The graduated scale curls in the graduated scale reel, the sai shi dish with the graduated scale is connected, the graduated scale reel is installed the central point of protractor sector, holds the hand and connects on the graduated scale reel.

In order to make the Sai's dish sink to the bottom smoothly for measurement, the Sai's dish in this embodiment is provided with a counterweight, and the counterweight is divided into two parts, and round platform shape counterweight is added to the upper bottom, and toper counterweight is added to the lower bottom. Dividing the front surface of the dish with the diameter of 20cm shown in figure 1 into 4 equal fan-shaped areas, and painting the areas to be black and white; the truncated cone-shaped and conical counterweights are divided into an upper part and a lower part to fix the plate, and the graduated scale reel is connected with the truncated cone-shaped counterweights by an iron ring, so that the Samsung disk is connected with the graduated scale reel.

Example 2

This example provides a method for measuring the transparency of a water body using the measuring device of example 1. first, we need to understand the measuring method adopted in the prior art, which is an ideal case of measuring the transparency of a water body, and in ideal cases, such as when the surface of water is calm and calm, and the measuring Seitz disk is just at the horizontal level, the reading displayed on the graduated scale is L₁(ii) a Then the Seitz disc is put into water and slowly shaken into the water until the Seitz disc is invisible, and the reading L on the graduated scale at the moment is recorded₂So the optical depth of water at this sampling point is L₀＝L₂-L₁。

However, in general, in practical situations, such as water surface or lake surface, and excessive wind and wave, the scale is bent or twisted, which interferes with the real recorded information of the data of the sampling point, so that it is necessary to improve the existing technology. Thus adopt the factThe measurement was carried out by the measuring apparatus in example 1, and the distance L from the observation point to the water surface was first measured in the same manner as in the conventional measurement₁The Seitz disc was then lowered into the water using the apparatus of example 1, and when the Seitz disc was placed in the water and was not visible, the angle α of the protractor and the scale reading L were noted₂'. although wind and waves make the scale deviate a certain angle, the reading will be read directly on the protractor and recorded as α, and the reading on the scale should display the vertical distance L₂＝L₂' cos α, so in this practical case the optical depth distance of the water transparency of the sample point is L₀＝L₂-L₁＝L₂′·cosα-L₁As shown in FIG. 2, the optical depth L of water in any case can be determined₀Accurate to centimeter and take 2 decimal places.

When carrying out the actual survey, adopt the utility model discloses the data of actual survey include the distance of survey point to the surface of water and survey point to the distance when the transparent circle is invisible soon, and add scale skew angle α according to actual conditions, application trigonometric function formula, only need the distance of twice survey a certain sampling point, just can be relatively fast, accurately obtain the optical water depth distance of this point, time and material resources have been saved, the interference of people for and other factors has been avoided, the error is little, the accuracy is high.

Through adopting the utility model discloses an above-mentioned technical scheme has obtained following profitable effect:

the utility model discloses a novel water transparency's measuring device, the device has added the protractor sector disc on current transparency survey device, this change can obtain water transparency through simple survey method and the accurate survey of calculation method in any water measuring environment, can be in order to solve the optics depth of water problem under actual conditions and the ideal condition, effectively avoid in the actual conditions measurer not good eyesight, conditions such as weather condition and light are not enough lead to the inaccurate problem of reading, and instrument operation is simple, the shang shou is fast, can calculate the actual optics depth of water in current waters, have the calculation scientificity, measure the characteristics of accuracy, make the measurement of water transparency swift effective, work efficiency and validity have greatly been improved.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
