[0028] The ecological environment refers to the quantity and quality of water, land, biological, and climate resources that influence human survival and development. It is a complex ecosystem crucial for sustainable social and economic development. The process of utilizing and transforming nature sometimes causes damage to the ecological environment, necessitating its protection and monitoring.

[0029] In the related art, since the texture of the rope is relatively soft, it is impossible to fix the position of the water quality monitor in the water, resulting in the water quality monitor being easily affected by the flow velocity of the water area, causing the water quality monitor to move due to the impact of the water flow, thereby causing the position monitored by the water quality monitor to change, affecting the accuracy of the monitoring.

[0030] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a water quality monitoring device. When it is necessary to monitor water areas with rapid water flow, it is only necessary to start the lifting component 23 to push the fixed rod 24 downward. After the fixed rod 24 moves downward to the predetermined position, the lifting component 23 is stopped, and then the line is released through the retracting component 21, and the monitoring probe 14 is put into the water and continuously moved downward. As the monitoring probe 14 continues to descend in the water, it slides on the fixed rod 24 through the sliding sleeve 25, so that the monitoring probe 14 can move vertically downward to the predetermined monitored water level, and at the same time the fixed rod 24 will support the monitoring probe 14.

[0031] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0033] During use, according to the water level of the water area to be monitored, the lifting component 23 is started, and the lifting component 23 pushes the fixed rod 24 to move downward. After the fixed rod 24 moves downward to the predetermined position, the lifting component 23 is stopped, and then the line is released through the retracting component 21, and the monitoring probe 14 is put into the water and continuously moved downward. As the monitoring probe 14 continues to descend in the water, it slides on the fixed rod 24 through the sliding sleeve 25, so that the monitoring probe 14 can move vertically downward to the predetermined monitored water level. At the same time, the fixed rod 24 will support the monitoring probe 14, thereby increasing the stability of the monitoring probe 14, preventing the monitoring probe 14 from being offset by the impact of the water flow, and improving the monitoring accuracy of the monitoring probe 14.

[0034] Specifically, the monitoring probe 14, model CK-DCS-A1, operates based on the principle of fluorescence quenching. The probe contains a fluorescent substance. When excitation light of a specific wavelength strikes the fluorescent substance, it emits fluorescence of a specific wavelength. Dissolved oxygen molecules in the water interact with the fluorescent substance, weakening the fluorescence intensity. By measuring parameters such as the intensity and lifetime of the fluorescence, the dissolved oxygen concentration in the water can be calculated, although this is not shown in the accompanying drawings.

The rotating threaded rod 232 pushes the fixed rod 24 up and down through the movable plate 233, and cooperates with the monitoring probe 14 to monitor different water levels.

[0038] In some embodiments, a slider 28 is provided at one end of the movable plate 233, and a second slide groove 281 is provided on the inner side of the support column 22 to cooperate with the slider 28, supporting the movable plate 233 and increasing the stability of the movable plate 233 pushing the fixed rod 24 to move up and down in the water.

[0039] In some embodiments, the retraction and extension assembly 21 includes: a shell 211 disposed on the top of the support plate 12 and located on one side of the second motor 231; a winch 212 disposed inside the shell 211; a first motor 213 disposed on one side of the winch 212, and the winch 212 is driven by the first motor 213 to rotate forward or reverse, and the monitoring probe 14 is retracted and extended through the rope.

[0040] In some embodiments, fixing screws 15 are provided on the bottom plate 13 and pass through the bottom plate 13 , and the pillar 11 is fixed to the river bank by the fixing screws 15 .

[0041] In some embodiments, a support rod 16 is provided on the outside of the column 11 and is located at the bottom of the support plate 12 to support the support plate 12 and increase the stability and balance of the support of the column 11.
