[0020] See also Figure 1-Figure 4 A water quality detection sampling device comprises an arc-shaped dome 1 and a bottom plate 3 which are sealed and assembled together, and a PLC control module 8 which is electrically connected to a water pipe valve. An operation panel 5 which integrates an operation button, a charging port and a display screen is arranged at one end of the arc-shaped dome 1. The operation panel 5 is electrically connected to a battery box 7 which is arranged inside the arc-shaped dome 1 and integrates a battery and a power supply circuit. The battery box 7 is electrically connected to the PLC control module 8. The PLC control module 8 is electrically connected to a sewage detection sensor 9 which is externally arranged in a water pipe. The PLC control module 8 is electrically connected to a motor 10, which is transmission-connected to a pump 11. One end of the pump 11 is connected to a liquid extraction pipe 12 which is placed in the water pipe, and the other end of the pump 11 is connected to three sewage storage bottles 15 respectively through three-way valves 14. An electromagnetic valve 16 which is electrically connected to the PLC control module 8 is installed between the three-way valve 14 and the sewage storage bottle 15.

[0021] Specifically, a plurality of permanent magnets 2 are fixedly embedded in the top of the arc-shaped arch 1. This arrangement facilitates the use of a plurality of permanent magnets 2 to fix and adsorb the device on the top of the water pipe, thereby preventing impurities in the sewage from accumulating at the end of the liquid extraction pipe 12 and causing blockage.

[0022] Specifically, a waterproof shield 4 is provided outside the operation panel 5, and the waterproof shield 4 is detachably sealed and clamped together with the arc-shaped arch 1. Such a setting can provide further waterproof function for the operation panel 5 through the waterproof shield 4, thereby improving the waterproof effect and service life of the device.

[0023] Specifically, a material taking door 6 is installed at the other end of the arc-shaped arch 1 corresponding to the operation panel 5 through a sealed hinge. This arrangement facilitates the replacement of the sewage storage bottle 15 through the material taking door 6, thereby re-inspecting the extracted samples sealed in the sewage storage bottle 15 to ensure monitoring accuracy.

[0024] Specifically, a counterweight block 13 is installed at the end of the liquid extraction pipe 12. This arrangement allows the end of the liquid extraction pipe 12 to be located at the center of the water pipe through the counterweight block 13, thereby facilitating the extraction of sewage.

[0025] Specifically, the sewage storage bottle 15 includes a bottle body 1501 made of corrosion-resistant plastic material, a threaded cap 1503 is provided on the top of the bottle body 1501 for easy sealing connection with the three-way valve 14, and a waterproof breathable membrane 1502 is provided on the side of the bottle body 1501. This arrangement makes it easy to use the threaded cap 1503 to seal and screw the sewage storage bottle 15 and the three-way valve 14 together. At the same time, when extracting sewage samples, the gas in the sewage storage bottle 15 can be discharged through the waterproof breathable membrane 1502 to avoid excessive air pressure in the sewage storage bottle 15 affecting the extraction of samples.

[0026] Working principle: When using this device for water quality monitoring, first charge the battery integrated in the battery box 7 through the operation panel 5, and input instructions through the operation panel 5 to set the sampling interval, sampling times and other working parameters. Under the magnetic adsorption of the permanent magnet 2, fix the arc dome 1 above the water pipe, keep the sewage detection sensor 9 and the end of the suction pipe 12 in the middle of the sewage, and use the sewage detection sensor 9 to detect the water quality information of the sewage in real time, and feed back the detection results to the PLC control module 8 for processing. When the water quality data received by the PLC control module 8 meets the standard, no action is taken. When the PLC control module 8 When the water quality data received by the LC control module 8 exceeds the standard, the PLC control module 8 controls the motor 10 to start, and the motor 10 drives the pump 11 to operate, and the sewage in the water pipe is sucked into the water pipe through the suction pipe 12. At the same time, the PLC control module 8 controls the single solenoid valve 16 inside the three-way valve 14 to open, and closes the other two solenoid valves 16. The sewage sucked into the pump 11 is injected into the sewage storage bottle 15 through the opened solenoid valve 16 for storage, and a cycle action is completed. When the water quality in the water pipe is detected to exceed the standard for multiple times in a row, the PLC control module 8 controls the valve on the water pipe to automatically close and stop discharging sewage.
