Description

Technical Field

[0001] The utility model relates to the technical field of turbidity meters, in particular to a self-cleaning turbidity meter. Background Art

[0002] Suspended and colloidal particles in water cause previously colorless, transparent water to become turbid. The degree of turbidity is called turbidity. Turbidity is expressed in degrees. For example, 1 liter of water containing 1 mg of SiO2 produces 1 degree of turbidity, or Jackson's unit. The unit of turbidity is called the JTU (Jettl Turbidity Unit), where 1 JTU equals 1 mg / L of kaolin suspension. Modern instruments display turbidity in NTUs (Nephelometric Turbidity Units), also known as TUs. 1 TU = 1 JTU. Recently, the international consensus has been that the turbidity standard prepared using methenamine-hydrazine sulfate has the best reproducibility and has been adopted as the unified standard, FTU. 1 FTU = 1 JTU. Turbidity units and their relationships. Turbidity, or the degree of water turbidity, is caused by the presence of suspended matter such as silt, clay, organic matter, inorganic matter, plankton, and microorganisms. Common methods for measuring turbidity include spectrophotometry, visual turbidimetry, and nephelometers. The measurement unit used in the ISO standard is FTU (Fever Turbidity Unit), which is consistent with NTU (Nephelometric Turbidity Unit).

[0003] This technical solution still presents at least the following drawbacks: Existing turbidity meters typically place the turbidity probe into flowing water to measure turbidity. However, turbidity in the flowing liquid easily adheres to the light source detection end, affecting the accuracy of turbidity measurement. Therefore, improvements are urgently needed. Therefore, we propose a self-cleaning turbidity meter. Utility Model Content

In addition, during the turbidity probe detection process, the sleeve can be rotated along the direction of the annular groove on the turbidity probe, so that the sleeve can be driven to rotate automatically by the water flow. In addition, during the rotation of the sleeve, the rubber strip on the sleeve will follow the rotation, so that the rubber strip can clean the surface of the light source detection end, thereby reducing the impact of the film in the turbid liquid on the surface of the light source detection end on the accuracy of the turbidity probe.

[0011] Optionally, the rubber plates are distributed in a ring shape, and at least six rubber plates are provided.

[0012] By adopting the above technical solution, the rubber plate is provided so that the driving force of the water flow can be transmitted, thereby driving the sleeve to rotate.
