Description

Technical Field

[0001] This utility model relates to the technical field of pollution monitoring, and in particular to a device for monitoring the concentration of pollution in river water. Background Technology

[0002] To monitor the concentration of pollutants in river water in real time, it is necessary to install river water pollution concentration monitoring devices in the monitored rivers. For example, Chinese utility model patent CN219016292U discloses a river water pollutant concentration monitoring device. This monitoring device includes a pumping pipe, a pumping pump, and a pollutant concentration detection device. The pumping pipe is connected to a sampling assembly, which includes a tee pipe, a sampling tube, a control valve, a regulating pipe, and a drive assembly for driving the regulating pipe to rotate at the end of the sampling tube. The drive assembly is located on the sampling tube. The pumping pipe, the tee pipe, and the sampling tube are connected in sequence. The control valve is located on the sampling tube. Multiple inlets 'a' are evenly distributed at the end of the sampling tube. The regulating pipe is rotatably located on the outer circumference of the sampling tube, and multiple inlets 'b' are evenly distributed at the end of the regulating pipe. The input end of the pumping pump is connected to the top of the pumping pipe. The pollutant concentration detection device is connected to the output end of the pumping pump. This utility model can clean the inlets to ensure the pumping effect.

[0003] However, the existing monitoring devices are fixed installations, so the monitoring range is relatively small. When the pollution diffusion is poor, the pollutants accumulate in the river water, causing the pollutants to be clearly separated from the river water. If the sampling end cannot come into contact with the pollutants at this time, the pollution concentration in the water cannot be monitored, resulting in monitoring failure. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a river water pollution concentration monitoring device that can move flexibly on the river water body and monitor the river water pollution concentration, with a large monitoring coverage and high monitoring reliability.

[0005] This utility model discloses a river water pollution concentration monitoring device, comprising a hull and a rudder mechanism, with the rudder mechanism installed at the stern of the hull; it also includes a sampling tube, a three-way valve, a monitoring tube, a monitoring unit, an air extraction pipe, a water extraction pipe, and a water pump. The sampling tube is installed at the bottom of the hull, and the three-way valve is installed inside the hull. The upper end of the sampling tube is connected to the input end of the three-way valve, the input end of the monitoring tube is connected to one output end of the three-way valve, and the output end of the monitoring tube is connected to the detection inlet of the monitoring unit. The detection inlet of the monitoring unit is connected to the detection chamber. The system is interconnected: the input end of the air extraction pipe is connected to the other output end of the three-way valve; the output end of the air extraction pipe is connected to the inlet of the water pump; the input end of the water extraction pipe is connected to the air outlet of the monitoring unit, which is connected to the detection chamber of the monitoring unit; the output end of the water extraction pipe is connected to the inlet of the water pump; and the water pump's outlet pipe extends out from the stern of the hull. The hull houses the power supply and control units for the water pump, rudder mechanism, three-way valve, and monitoring unit, as well as communication and positioning units for communication with the higher-level monitoring system. All of the above are existing... The specific setup of the technology is not detailed here. During operation, the vessel floats on the river surface. A three-way valve is adjusted to connect the sampling tube and the air extraction tube. A water pump draws river water from the sampling and air extraction tubes and sprays it towards the stern of the vessel through the outlet pipe, propelling the vessel across the river. The rudder mechanism adjusts the angle to change the vessel's direction, allowing it to reach different positions in the river. Once the vessel reaches the monitoring position, the three-way valve is adjusted again to connect the sampling and monitoring tubes. The water pump then extracts air from the air extraction tube, allowing river water to pass through the sampling and monitoring tubes into the detection chamber of the monitoring unit. A sampling bottle can be placed in the detection chamber for sampling, or an online monitoring unit can be set up to directly detect the pollution concentration of the river water entering the chamber. The detection data is transmitted to the higher-level monitoring system via a communication unit. When the vessel reaches the shore, the sampling bottle can be removed for further monitoring. Compared to existing technologies, this technology allows for flexible movement on the river surface and monitoring of river pollution concentrations, offering a wide monitoring coverage and high reliability.

[0006] Preferably, it also includes a corrugated hose, the upper end of which is connected to the input end of the three-way valve via the corrugated hose; by setting the corrugated hose, the sampling tube can pitch and swing, and when it encounters an obstacle, the sampling tube bends, thereby allowing the hull to pass over the obstacle.

[0007] Preferably, it also includes a push rod, one end of which is rotatably connected to the bottom of the hull, and the other end of which is rotatably connected to the sampling tube; the piston rod of the push rod extends or shortens to push the sampling tube, thereby adjusting the angle of the sampling tube, and thus adjusting the depth of the input port of the sampling tube in the river water, so as to realize sampling and monitoring of water at different depths.

[0008] Preferably, it also includes a water expansion tube and a float. The water expansion tube is installed on the air extraction tube, and the float is movable inside the water expansion tube. When the water pump is running and pumping water through the sampling tube and monitoring tube to monitor the pollution concentration, air is extracted through the gap between the float and the inner wall of the water expansion tube, so that water in the river is sucked into the detection chamber of the monitoring unit. When the water enters the water expansion tube along the air extraction tube, the float floats up and is pushed by the buoyancy of the water to the top output port of the water expansion tube, thereby blocking the air extraction tube and preventing excess water from being extracted.

[0009] Preferably, it also includes a pan-tilt unit and a monitoring camera. The pan-tilt unit is installed on the hull, and the monitoring camera is installed on the pan-tilt unit. The monitoring camera is used for video monitoring of the river water and provides hardware support for monitoring water color changes using visual recognition technology. By installing the pan-tilt unit, the monitoring angle of the monitoring camera can be flexibly adjusted.

[0010] Preferably, it also includes an air monitoring unit, an air inlet, an air duct, and multiple monitoring probes. The air monitoring unit is installed on the hull, with an air inlet on the front end of the air monitoring unit. An air duct is installed inside the air monitoring unit, and the air inlet is connected to the air duct. Multiple monitoring probes are installed inside the air duct. Air from the river enters the air duct through the air inlet, and the concentration of harmful substances in the air is monitored by multiple monitoring probes, thereby indirectly monitoring the pollution concentration of the river water. By setting multiple different monitoring probes, the concentration of different pollutants can be monitored.

[0011] Preferably, it also includes a fan, and an air outlet is provided on the side wall of the air monitoring unit. The air outlet is connected to the air duct, and the fan is installed on the air outlet of the air monitoring unit. When the fan is running, it exhausts the air inside the air duct to the outside, accelerates the entry of outside air into the air duct through the air inlet, and improves the monitoring efficiency.

[0012] Compared with the prior art, the advantages of this utility model are: it can move flexibly on the river water body and monitor the concentration of pollution in the river water body, with a large monitoring coverage and high monitoring reliability. Attached Figure Description

This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example 1

All of these are existing technologies, and their specific configurations are not detailed here. During operation, the hull 1 floats on the river surface. The three-way valve 4 is adjusted to connect the sampling pipe 3 and the air extraction pipe 7. The water pump 9 draws river water from the sampling pipe 3 and the air extraction pipe 7 and sprays it towards the stern of the hull 1 through the outlet pipe, thus propelling the hull 1 along the river. The rudder mechanism 2... The angle is adjusted to change the direction of the hull 1, allowing it to reach different positions in the river. A corrugated hose 10 allows the sampling tube 3 to pitch and swing. When encountering an obstacle, the sampling tube 3 bends, allowing the hull 1 to pass over it. Once the hull 1 reaches the monitoring position, the piston rod of the push rod 11 extends or retracts to push the sampling tube 3, thereby adjusting its angle and the depth of the input port in the river water. This enables sampling and monitoring of water at different depths. The three-way valve 4 is adjusted and switched to allow the sampling tube to... When the sampling pipe 3 and monitoring pipe 5 are connected, the water pump 9 operates, extracting air from the pumping pipe 8, allowing river water to enter the detection chamber of the monitoring unit 6 through the sampling pipe 3 and monitoring pipe 5. While the water pump 9 is pumping water through the sampling pipe 3 and monitoring pipe 5 to monitor pollution concentration, air is extracted through the gap between the float 13 and the inner wall of the expansion tube 12, causing water from the river to be drawn into the detection chamber of the monitoring unit 6. When the water enters the expansion tube 12 along the air extraction pipe 7, the float 13 floats up and is pushed by the buoyancy of the water.

A sampling bottle can be set up in the detection chamber for sampling, or an online monitoring unit can be set up to directly detect the pollution concentration of the river water entering the detection chamber. The detection data is sent to the upper-level monitoring system through the communication unit. When the hull 1 reaches the shore, the sampling bottle can be removed for further monitoring. Compared with the existing technology, it can move flexibly on the river water and monitor the pollution concentration of the river water, with a large monitoring coverage and high monitoring reliability.
