Description

Technical Field

[0001] This utility model relates to the field of water quality testing technology, and in particular to a UVT measuring device. Background Technology

[0002] UVT measurement is based on the absorption characteristics of ultraviolet light by substances. When a beam of ultraviolet light of a specific wavelength passes through a sample being tested, some of the light is absorbed, reflected, or scattered, while the remaining light continues to propagate through the sample. By measuring the intensity of the transmitted ultraviolet light, the UVT value of the sample can be calculated, determining whether the water quality meets safety standards.

[0003] Water quality measurement typically requires water sampling. After collection, the samples need to undergo a series of processing steps, such as preservation, transportation, extraction, and purification, to ensure the quality and stability of the samples. These steps all take time, making sample measurement time-consuming. Utility Model Content

[0004] The purpose of this invention is to provide a UVT measuring device to solve the problems and defects mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a UVT measuring device, including an electrical box, a light source box on the top of the electrical box, a sensor box fixedly installed on the front outer wall of the light source box, a sensor embedded in the front of the sensor box, a lamp sleeve embedded in one side of the light source box, an ultraviolet lamp sleeved inside the lamp sleeve, and aluminum foil pasted on the inner wall of the light source box to increase ultraviolet intensity. It also includes a DC fan fixedly installed on the rear inner wall of the light source box, and a cuvette fixedly installed on the front inner wall of the light source box. The cuvette is located between the sensor and the ultraviolet lamp, and the sensor, cuvette, and ultraviolet lamp are on the same horizontal plane. This device can quickly assess the content of suspended solids and organic matter in water and effectively deliver ultraviolet dose, thereby achieving ideal disinfection results. Given the significant differences in water quality conditions in different regions, UVT can help adapt to these changes and ensure effective disinfection under various water quality conditions. Especially in low UVT environments, by adjusting the UV system parameters, excellent disinfection results can be provided under economical and efficient conditions.

[0006] Preferably, the sensor box has a light-transmitting hole on the rear side, and the light source box has a light-transmitting hole on the front side, with the sensor box light-transmitting hole and the light source box light-transmitting hole located between the sensor and the cuvette.

[0007] Preferably, the cuvette has a backlight side on its front side and a light-receiving side on its rear side.

[0008] Preferably, the front side of the electrical box and the front side of the sensor have a connection hole, and a sensor signal wire is inserted into the connection hole. The front side of the electrical box also has a socket, and an electrical box power cord is inserted into the socket. One end of the electrical box power cord is fixedly connected to a three-wire plug.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This UVT measuring device can control the UV dose within the design range based on the UV transmittance. When the UV transmittance is low, the UV reactor can extend the water flow irradiation time or increase the number of UV lamps. When the UV transmittance is high, the water flow irradiation time or the number of UV lamps can be reduced. This ensures disinfection effect, saves energy and reduces consumption, and also reduces measurement time, making it suitable for water quality conditions in different regions.
