AI Technical Summary
Existing methods for measuring transparency in water are inaccurate and easily affected by water flow and ship movement, making precise measurements impossible.
The device employs a Seymbo disc with a tower-type shrinkage scale and a lifting eye screw structure. By combining the Seymbo disc and the tower gauge, the device is vertically fixed through the lifting eye screw, avoiding the influence of water flow and ship sway, and accurately measuring transparency.
It enables accurate measurement of transparency in environments with water flow and ship swaying, with a measurement accuracy of up to 0.1 cm, and is suitable for on-site measurement of surface water and sewage.

Abstract
Description
A device for measuring transparency in water Technical Field
[0001] This utility model relates to a device for measuring transparency in water, belonging to the field of water transparency measurement technology. Background Technology
[0002] Currently, the Seiler disk (transparency disk) method is commonly used for measuring water transparency on-site. The Seiler disk, also known as the black and white disk, is a circular disk that is submerged in water, and the water depth at which the disk is just barely visible is used to represent transparency. The transparency disk (also known as the Seiler disk) is made by making a small hole in the center of a circular plate, threading a lead wire through it, placing a lead weight below, and tying a rope to the top. A colored silk thread or paint is used to mark every 10 cm along the rope. At present, the Seiler disk method (B) in "Methods for Monitoring and Analysis of Water and Wastewater" (Fourth Edition Supplement) is commonly used to measure the transparency of water. Although the Seiler disk method is simple and easy to implement, it can only be used as a rough measurement method. This method has poor accuracy, is not precise enough, and is susceptible to interference from factors such as water flow and ship movement. It is only suitable for rapid on-site testing and occasions where high transparency requirements are not required. Summary of the Invention
[0003] To overcome the shortcomings of the existing technology, this utility model provides a water transparency measuring device. This device has strong anti-interference capabilities, avoids measurement interference caused by factors such as water flow and boat swaying, and can measure vertically and accurately without being affected by factors such as water flow and boat swaying. It has high measurement accuracy and is simple and flexible to operate.
[0004] The technical solution adopted by this utility model to solve its technical problem is: a water transparency measuring device, including a Seymbidium plate, a scale, and a lifting eye screw. The Seymbidium plate is a circular plate, and a scale is set at the center of the top of the Seymbidium plate in a vertical direction. A threaded hole is provided inside the bottom end of the scale.
[0005] A lifting eye screw is provided at the center of the bottom of the Sejuani disc. The lifting eye screw consists of a screw and a lifting eye, which are an integral structure. The screw of the lifting eye screw passes through the washer and the center hole of the Sejuani disc and is threaded to the threaded hole at the bottom of the leveling gauge.
[0006] Furthermore, the surface of the Seidon disk is arranged in alternating black and white patterns, and is divided into four equal parts.
[0007] Furthermore, the leveling rod is a leveling rod with a tapered shape, and its two sides are respectively provided with a coarse measuring surface with graduations and a fine measuring surface with graduations.
[0008] The beneficial effects of this utility model are as follows: This utility model is an improvement and innovation on existing measurement methods and devices. By using a scaled ruler or telescopic ruler with a transparency disc, a new type of device for measuring transparency in water is established. This device has strong anti-interference capabilities, avoids measurement interference caused by factors such as water flow and boat swaying, and can measure vertically and accurately without being affected by factors such as water flow and boat swaying. It has high measurement accuracy, is simple and flexible to operate, and the measurement results can be accurate to 0.1cm. It is suitable for on-site measurement of transparency in surface water and sewage. Attached Figure Description

[0016] As shown in Figures 1-4, a water transparency measuring device includes a Seymbidium disk 1, a scale 2, and a lifting eye screw 3. The Seymbidium disk 1 is a circular plate with a black and white pattern on its surface, divided into four equal parts. A scale 2 is vertically positioned at the center of the top of the Seymbidium disk 1. The scale 2 is a tapered, tower-shaped device. The scale 2 has a coarse measuring surface with graduations and a fine measuring surface with graduations on its two sides. A threaded hole 201 is provided inside the bottom of the scale 2.
[0017] A lifting eye screw 3 is provided at the center of the bottom of the Sess plate 1. The lifting eye screw 3 includes a screw 301 and a lifting eye 302, which are integral structures. The screw of the lifting eye screw 3 passes through the washer and the center hole of the Sess plate 1 and is threaded to the threaded hole 201 at the bottom of the scale 2.
[0018] During use, simply pull out the scale 2. The scale 2 is a rectangular pull-out type, and a retaining spring pops out with each section pulled out. Ensure the retaining spring is in place during use. Then, place the transparency measuring device in the water. The vertical measurement of the scale 2 can measure the depth of the Seidon disk 1 in the water, while avoiding interference from factors such as water currents and boat swaying. Gradually sink the Seidon disk 1 until the white color on the surface of the Seidon disk 1 is just no longer visible. Record the scale reading as the transparency value in cm. When the Seidon disk 1 sinks to the point where the black and white pattern on the surface of the disk is just no longer visible, record the corresponding scale reading on the scale 2, which is the transparency value of the water sample. After measurement, simply retract the scale 2. The Seidon disk 1 can be replaced by loosening the eyelet screw 3. This underwater transparency measuring device is simple to use, has strong anti-interference capabilities, and high measurement accuracy.
