Description

Technical Field

[0001] The utility model relates to the technical field of water ecological monitoring, in particular to a shore-based box for water ecological monitoring. Background Art

[0002] Water ecological monitoring refers to the process of monitoring and measuring the types of pollutants in water bodies, their concentrations and changing trends, and evaluating water quality. It provides a scientific basis for water resource management, ecological environmental protection, pollution control, and ecological restoration, timely discovers and controls water pollution problems, and protects the aquatic ecological environment. Water ecological monitoring methods include fixed-point monitoring, cross-section monitoring, mobile monitoring, remote sensing monitoring, and model simulation. Shore-based boxes are a type of equipment for fixed-point water ecological monitoring. They are installed at fixed locations on the shore to regularly collect water and biological samples for analysis and are used to monitor rivers, lakes, and other water bodies.

[0003] Since the shore-based water ecological monitoring box needs to conduct long-term, continuous and systematic monitoring at a fixed location, and there is a lot of suspended matter in the water, suspended matter and other substances will remain in the detection pool of the shore-based box. Long-term measurement will cause these substances to accumulate, resulting in reduced detection accuracy. In addition, water samples will precipitate during measurement, resulting in uneven distribution of substances, which will also reduce the accuracy of sampling detection. Summary of the Invention

The screw 301 rotates at the top of the box 1. Moving in the vertical direction, the screw 301 drives the connecting tube 304 to rotate and move in the vertical direction through the two first connecting rods 305. The connecting tube 304 drives the stirring blade 307 and the brush plate 308 to rotate and move in the detection tank 201. The rotation of the connecting tube 304 drives the connecting disk 309 to rotate through the guide rod 312. The rotation of the connecting disk 309 drives the brush plate 313 to rotate and clean in the detection tank 201. The sliding guide rod 312 ensures that the connecting disk 309 does not move in the vertical direction with the connecting tube 304 when it rotates.

[0030] Working principle: Start the water pump 203 to extract samples from the monitored water body and transport them to the top of the filter frame 202 through the water pipe 204, and the water flows through the filter frame 202 into the detection pool 201. The filter holes filter out branches, water plants and debris in the sample in the filter frame 202. The detection pool 201 stores the filtered samples for inspection. The multi-parameter sensor 205 measures the pH value, dissolved oxygen, conductivity, turbidity, nutrients, heavy metals and other data of the sample. The data controller 206 stores, processes and analyzes the measured data and transmits it to the monitoring center through the network. During the inspection process, the motor 303 is started to drive the screw 301 to rotate counterclockwise. The screw 301 rotates counterclockwise at the top of the box 1 and moves downward in the vertical direction. The downward movement of the screw 301 drives the sliders on both sides of the motor 303 to move downward in the slide groove of the support plate 302. The screw 301 drives the connecting pipe 303 through the two first connecting rods 305. 04 rotates counterclockwise and moves downward in the vertical direction to clean. The connecting pipe 304 drives the stirring blade 307 and the brush plate 308 to rotate and move in the detection pool 201. The stirring blade 307 stirs the sample in the detection pool 201 evenly, and the brush plate 308 scrubs the inner wall of the detection pool 201. The connecting pipe 304 rotates counterclockwise and drives the connecting plate 309 to rotate counterclockwise through the guide rod 312. The rotation of the connecting plate 309 drives the brush plate 313 to rotate and clean in the detection pool 201. When the brush plate 308 is close to the brush plate 313, the motor 3 03 drives the screw 301 to rotate clockwise, and the screw 301 rotates clockwise on the top of the box body 1 and moves upward in the vertical direction. The upward movement of the screw 301 drives the sliders on both sides of the motor 303 to move upward in the slide groove of the support plate 302. The screw 301 drives the connecting pipe 304 to rotate counterclockwise and move upward in the vertical direction through the two first connecting rods 305. The connecting pipe 304 drives the stirring blade 307 and the brush plate 308 to rotate and move in the detection tank 201. The brush plate 308 brushes the inner wall of the detection tank 201. The connecting pipe 304 rotates counterclockwise through the guide rod 312 to drive the connecting disk 309 to rotate clockwise. The rotation of the connecting disk 309 drives the brush plate 313 to rotate and clean in the detection tank 201. When the connecting pipe 304 moves up and down, it slides on the outside of the guide rod 312 so that the connecting disk 309 does not move along the vertical direction with the connecting pipe 304 when it rotates. Repeat the cleaning and stirring. After the test is completed, pull the handle to pull out the filter frame 202 to clear the debris inside, open the valve of the discharge pipe at the bottom of the detection tank 201 to discharge the tested sample, and then close the valve.
