Description

Technical Field

[0001] This utility model belongs to the field of COD sensor technology, specifically relating to an optical COD sensor with a cleaning brush. Background Technology

[0002] Chemical oxygen demand (COD) refers to the amount of strong oxidant consumed by reducing substances in wastewater under certain conditions when treated with strong oxidants. For industrial wastewater research, wastewater treatment plant effectiveness evaluation, and urban wastewater quality monitoring, COD plays a crucial role in total pollutant control and water environment management. With societal development, people are increasingly emphasizing the protection of their living environment, making water environment monitoring and pollution control particularly important. The concepts of the Internet of Things (IoT), smart water management, the river chief system, and grid-based management are gaining traction, making front-end monitoring data for rivers, lakes, urban canals, and tap water and secondary water supply systems indispensable. In this new context, digital COD sensors can be integrated with the IoT industry to achieve grid-based water quality management and river chief system responsibility zoning.

[0003] Existing optical COD sensors with cleaning brushes still have some drawbacks. In most cases, the cleaning brush needs to be replaced by removing screws during use. During the disassembly process, screws are easily lost, which consumes time when disassembling and replacing the cleaning brush. To address this, we propose an optical COD sensor with a cleaning brush. Utility Model Content

[0004] The purpose of this invention is to provide an optical COD sensor with a cleaning brush, in order to solve the problems mentioned in the background art, such as the inconvenience of replacing the cleaning brush with the screw and the easy loss of the screw.

[0010] Preferably, a power cord is provided on the top of the COD sensor body, and the power cord is fixedly connected to the COD sensor body.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. The COD sensor body has a detection groove inside, a connecting sleeve inside the detection groove, a connecting frame on one side of the connecting sleeve, a lead screw inside the connecting frame, a knob on one end of the lead screw, and a threaded moving block on the surface of the lead screw. The threaded moving block drives the limit plate to move. The limit plate, together with the connecting frame, clamps and fixes the cleaning brush, and releases the cleaning brush for replacement. This realizes the function of replacing the cleaning brush of the optical COD sensor with a cleaning brush, and improves the efficiency of replacing the cleaning brush of the optical COD sensor with a cleaning brush.

[0012] 2. The optical COD sensor body has an internal light channel, a lens inside the light channel, a drive shaft inside the COD sensor body, and a power cord on the top of the COD sensor body. This enables the optical COD sensor with cleaning brush to be used as a whole, improving the stability of the optical COD sensor with cleaning brush. Attached Figure Description
