Description
Technical Field
The utility model relates to a water transparency measures the field, concretely relates to simple and easy double mode water transparency on-site determinator.
Background
In river and lake water environment monitoring, water transparency is one of conventional water quality monitoring indexes, is the most direct sensory index for detecting water environment quality and water quality, reflects the light transmittance of water, and is closely related to suspended sediment concentration, suspended matter content, colored soluble matter content and other factors in water. The transparency of the water body is reduced, so that not only can the sensory properties of the water bodies of rivers and lakes be directly influenced, but also the growth and development of aquatic plants and aquatic organisms can be directly influenced. At present, the existing water transparency field measurement technology and method are mainly divided into two types: the first type is a measurement and improvement method based on a Seattle disk (transparent disk) method which has been used for hundreds of years, a black-and-white alternating disk (generally made of acrylic or PC) with the diameter of 15-30 cm is used, a central hole of the disk is penetrated by a string or a lead wire (tied or not tied with a counterweight such as a plumbum hammer, a hanging block and the like), the disk is flatly placed in water and gradually sinks until the black-and-white alternate color of the disk surface is just not seen, then the disk surface is recorded to drop to the depth, and the water quality transparency is obtained. The second type is a measurement method mainly using an optical sensor or a pressure sensor, and an optical signal or a mechanical signal is sensed and measured by a light-emitting system, a visual sensor or a pressure sensor, so as to determine the transparency of the water body.
The above two methods have advantages, disadvantages and shortcomings. The first type of measurement method has the advantages of simple structure, convenient operation, easy carrying, simplicity, intuition and the like, and also has the following main defects and shortcomings: the device is influenced by factors such as wind waves, flow velocity, buoyancy of a water body and the like in actual operation, the problem of drift can occur when the Samson dish is used for launching measurement, the dish body, the measuring rope or the measuring tape can be inclined, the horizontality of the Samson dish can not be kept, and reading errors are caused, so that the measurement accuracy is influenced; when the balance weights such as the measuring rope, the measuring tape, the plumb bob, the hanging block and the like are used, the balance weights are not easy to be folded and unfolded, and are often wound, so that the measuring progress is influenced; when measuring deeper depth of water, receive the disk body stopper shi dish of water pressure influence and easily take place fracture breakage at the lift in-process, life is short, brings the inconvenience for on-the-spot survey crew. The second type of measurement method has the advantages of rapid measurement, small relative error, reduction of the working strength of measurement personnel and the like, and also has the following main defects and shortcomings: the design of the detection device is too complex, and the equipment purchase and later maintenance costs are higher; the main influence factors of the transparency of different water bodies are different, so that the optical properties, suspended matters, dissolved matters and the like of the water bodies are greatly different, and the comparative reliability of data among different water bodies is greatly reduced by using data measured by using the same set of optical sensor or pressure sensor as a main measuring method. From the above analysis, for the convenience of transverse comparison of water transparency and the convenience and easiness in operation of measurement, the measurement method based on the Seattle disk may be more suitable for the water bodies in rivers and lakes, but the defects and shortcomings of the measurement method based on the Seattle disk need to be overcome, and reading errors and relative measurement errors are reduced as much as possible.
Therefore, how to provide a simple, convenient and fast water transparency measuring device with easy operation and small relative error to improve the measuring accuracy and precision is one of the technical problems to be solved by those skilled in the art.
In order to solve the above problems, we have made a series of improvements.
