Description

Be used for high velocity of flow water transparency to detect and use measuring disk

Technical Field

The utility model relates to the field of environmental detection, in particular to a measuring disc for detecting the transparency of a high-flow-rate water body.

Background

The transparent disc, also known as the Seitz disc, was made in 1865 and was initially a pure white disc of 30cm diameter for measuring transparency in seawater. The disc body is arranged on a line and slowly descends along with the disc body in water until the disc body descends to a certain depth and the disc is just invisible, and the depth is used as a technical parameter for measuring the transparency of water. The water transparency is used as a physical index commonly used in water quality monitoring and is used for describing visual indexes of physical and chemical performances of natural water such as lakes, rivers and the like. However, because the ecological environments of various water bodies in nature are complex, the transparency is often accurately measured under the requirements of high flow speed and large storms, and because the transparent dial has a large diameter and is suspended by a soft rope, the rope cannot be kept vertical under the environments, and the transparent dial is also often deviated, so that a large error exists between the measured value and the actual value.

In the current actual detection work, a measuring tape is usually adopted to replace a sampling rope, and methods such as sinking quality and the like are increased, but the problem cannot be completely and effectively solved, and the measurement accuracy is low.

SUMMERY OF THE UTILITY MODEL

The technical problems to be solved by the utility model are as follows: the existing measuring disc cannot solve the problem that the measuring accuracy is low due to the deviation of a sampling rope under the condition of high-flow-speed water; further provides a measuring disc for detecting the transparency of the high-flow-rate water body.

The technical scheme adopted by the utility model for solving the technical problems is as follows: the measuring disc for detecting the transparency of the high-flow-velocity water body comprises a take-up and pay-off mechanism, a handle, an angle scale, a level gauge, a detecting disc, a heavy hammer and a plastic ruler, wherein the handle is installed on the outer side wall of the take-up and pay-off mechanism, the angle scale and the level gauge are fixedly installed on the lower surface of the take-up and pay-off mechanism from inside to outside in sequence, the heavy hammer is fixedly installed on the lower surface of the detecting disc, and the detecting disc is connected with the take-up and pay-off mechanism through the plastic ruler.

Compared with the prior art, the utility model has the following beneficial effects:

1. by arranging the angle scale below the take-up and pay-off mechanism, when the plastic ruler is influenced by high-flow-velocity water body to deviate, the deviation angle of the plastic ruler can be read, so that the depth of the transparent scale in water can be accurately calculated;

2. the level gauge is arranged below the angle scale, and the purpose of the level gauge is to keep the device in a horizontal state, namely when a sphere in the level gauge is at the 0-degree position of the angle scale, the device is in the horizontal state, so that the device is ensured not to cause inaccurate measurement due to human factors;

3. the wrench ensures that the plastic ruler can be freely folded and unfolded.
