Description
Technical Field
[0001] The utility model relates to the technical field of water quality monitoring, in particular to a town river water quality monitoring system. Background Art
[0002] Urban river water quality monitoring refers to the process of regular or irregular testing and evaluation of the water quality of urban rivers through various means.
[0003] The functions of water quality monitoring include: timely detection of water pollution problems: through regular water quality monitoring, abnormal water quality can be detected in time, the source of pollution can be determined, and corresponding measures can be taken to control it to prevent further spread of pollution. Scientific assessment of water environment conditions: through monitoring of river water quality, we can understand the water quality status of the water body, the degree of pollution, and the location and type of pollution sources, so as to scientifically evaluate the water environment and provide a basis for water pollution prevention and control. Improve the scientificity and efficiency of water pollution prevention and control: through water quality monitoring, we can understand the status of water pollution, timely detect pollution sources and control them, thereby reducing the damage caused by pollution to the environment and improving the scientificity and efficiency of water pollution prevention and control. Promote the sustainable use of water resources: by monitoring river water quality, we can timely detect and solve water pollution problems, protect the ecological balance and environmental quality of water bodies, and ensure the sustainable use of water resources.
[0004] However, when the prior art is actually used, when using a water quality monitoring system to monitor the water quality of urban rivers, the usual water quality monitoring system uses a suspended sensor to float in the urban river to monitor the water quality. However, when the sensor is floated in the urban river to monitor the water quality, since urban rivers are generally narrow and the water flow is more complicated, when monitoring the water quality of narrow urban rivers with fast-flowing water, the suspended sensor is easily washed away by the water flow, which makes the water quality monitoring data prone to deviations.

When the transmission gear rotates, the force generated by the meshing connection between the lower end of the transmission gear and the transmission rack will drive the U-shaped mounting platform to move left and right. When the U-shaped mounting platform moves left and right, it will drive the lower end of the supporting roller to roll along the inner walls on both sides of the I-beam, so that the supporting roller can play a rolling support role for the left and right movement of the U-shaped mounting platform. When the U-shaped mounting platform moves left and right, it will synchronously drive the monitoring box and the water quality sensor module to move left and right for adjustment, thereby achieving stable monitoring of the water quality of urban rivers while facilitating the left and right movement of the monitoring position.
