[0002] Ship-borne or shore-based water nutrient salt detection and early warning devices play a key role in water environment monitoring. The main purpose of such devices is to monitor the nutrient salt content in water bodies, which mainly include nitrogen, phosphorus and other elements. These are key nutrients in water bodies, but excessive nutrients may cause eutrophication of water bodies and cause algae outbreaks. Such devices include sensor systems, data acquisition units, processing systems and communication modules to ensure efficient acquisition, analysis and transmission of water quality data, and realize real-time monitoring and early warning of the concentration of nutrients such as nitrogen and phosphorus in water bodies;

[0003] For example, the ship-borne or shore-based water nutrient automatic detection and early warning device disclosed in the authorization announcement number CN207730675U includes an equipment platform, a water sampling pump, a sedimentation tank, a backwash filter, a pressure pump, a detection tank one, a detection tank two, a nutrient detection instrument, a multi-parameter water quality sensor, and a data transmission and early warning system; the nutrient detection instrument is suspended at the center of the detection tank one through an instrument support frame; the multi-parameter water quality sensor is suspended at the center of the detection tank two through an instrument support frame; each detection instrument is suspended at the middle position inside the upper mouth of the detection tank through a detection instrument bracket for long-term continuous monitoring, and is transmitted to the user server through a data transmission and early warning module. However, when controlling the sampling depth of the water pipe in the water body, this technical solution requires the staff to continuously unwind the pipe, and after the water sampling is completed, the water pipe needs to be manually reeled in. Manually reeling in the water pipe requires additional time and labor, which reduces the sampling efficiency, especially when a large amount of sampling or frequent monitoring is required, which brings trouble to the staff's deep-level water nutrient detection.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-4 , the utility model provides an embodiment: a shore-based water body nutrient salt automatic detection and early warning device, comprising a right-angle frame 1 and a reduction motor 3 installed on the outer wall of one side of the right-angle frame 1, the output end of the reduction motor 3 is installed with a transmission shaft 10 through a coupling, the outer peripheral surface of the transmission shaft 10 is wound with a plurality of turns of a liquid inlet hose 9, a housing 4 is fixed on one side of the top of the right-angle frame 1, and the housing 4 and a sample collecting tube 6 are installed on one side of the top of the housing 4, a multi-parameter water quality detector 11 is installed on one side of the interior of the sample collecting tube 6, a right-angle liquid inlet pipe 7 is installed on the top of the sample collecting tube 6, a micro water pump 8 is installed at one end of the right-angle liquid inlet pipe 7, the top of the liquid inlet hose 9 is connected to the liquid inlet of the micro water pump 8, a PLC control panel 2 is installed on the outer wall of the other side of the right-angle frame 1, and the output end of the PLC control panel 2 is electrically connected to the sound and light alarm 5, the micro water pump 8, and the input end of the reduction motor 3;

[0019] The reduction motor 3 drives the transmission shaft 10 to rotate, so that the liquid inlet hose 9 wound on the outer surface of the transmission shaft 10 is actively unwound, and then the liquid inlet hose 9 is continuously sunk into the shore-based water body to be detected, thereby controlling the depth position of the end of the liquid inlet hose 9 in the shore-based water body;

[0020] A metal pipe head is installed at the bottom end of the liquid inlet hose 9, and the metal pipe head can be sunk into the shore-based water body more quickly;

[0021] A drain pipe 601 is installed on one side of the bottom end of the sample collecting tube 6, and a switch valve is installed on the top end of the drain pipe 601. After completing the water sample collection and testing, the staff can open the switch valve at the end of the drain pipe 601, so that the switch valve is in a normally open state, and then the sample liquid in the sample collecting tube 6 is discharged through the drain pipe 601 and the switch valve;

[0022] A vertical bearing seat 101 is fixed to one side of the top of the right angle frame 1, and the transmission shaft 10 is rotatably mounted inside the vertical bearing seat 101. When the transmission shaft 10 rotates to reel in or unreel the liquid inlet hose 9, the vertical bearing seat 101 improves the rotation stability of the transmission shaft 10.

[0023] A shaft seat 12 is fixed to the bottom end of the housing 4, and a stirring shaft 13 is rotatably installed inside the shaft seat 12. The top end of the stirring shaft 13 extends to the inside of the sample collecting tube 6. A bevel gear transmission structure 14 for power connection with the transmission shaft 10 is installed at the bottom end of the stirring shaft 13. The bevel gear transmission structure 14 includes a driven bevel gear installed at the bottom end of the stirring shaft 13 and an active bevel gear installed at one end of the surface of the transmission shaft 10. The active bevel gear and the driven bevel gear are meshed with each other.

[0024] When the liquid inlet hose 9 completes sample liquid collection and is reeled up, the rotational power of the drive shaft 10 is transmitted to the stirring shaft 13 through the bevel gear transmission structure 14, and the sample liquid in the sample collecting tube 6 is actively mixed by the stirring shaft 13. By realizing synchronous mixing processing, it is ensured that the sample in the sampling tube does not stratify or precipitate during the reeling process, thereby obtaining a more representative water sample and reducing the error caused by local concentration differences.

[0025] When the embodiment of the present application is in use, the staff first arranges the device at the point to be detected, and then the staff turns on the reduction motor 3 through the PLC control panel 2 to work, and the reduction motor 3 drives the transmission shaft 10 to rotate, so that the liquid inlet hose 9 wrapped around the outer surface of the transmission shaft 10 is actively unwound, and then the liquid inlet hose 9 is continuously sunk into the shore-based water body to be detected, so as to control the depth position of the end of the liquid inlet hose 9 in the shore-based water body. When the end of the liquid inlet hose 9 reaches the specified depth, the staff stops the reduction motor 3 and turns on the micro water pump 8 through the PLC control panel 2, and the micro water pump 8 pumps the shore-based water body through the liquid inlet hose 9, straight The liquid is sucked into the sample collecting tube 6 by the angle liquid inlet tube 7, and the collected liquid sample is detected by the multi-parameter water quality detector 11. The multi-parameter water quality detector 11 obtains water quality data and identifies and analyzes various nutrients in the water body. The information is sent to the PLC control panel 2. Once the PLC control panel 2 detects that the nutrients in the water body exceed the safety standard, it immediately controls the sound and light alarm 5 to send out a warning signal. The device can achieve faster and more accurate control of the sampling depth of the water pipe, reduce the tediousness and time consumption of manual operation, and can significantly improve the efficiency of sampling, especially in cases where frequent monitoring or large-scale sampling is required, providing more convenient conditions for timely acquisition of data.
