[0041] When the chemical industrial park safety monitoring device of the present invention is in use, it includes the following steps. Step 1: Place the chemical industrial park safety monitoring device at a preset position in the wastewater tank. In the initial state, the floating platform floats on the water surface, and the water collection tank is located at a first preset height below the floating platform (the first state). Step 2: Control the motor to start. The motor drives the connecting rod to rotate, and the connecting rod drives the first spiral blade to rotate. The first spiral blade lifts the wastewater in the wastewater tank into the water guide groove. The wastewater in the water guide groove flows out through the water guide pipe and impacts the driving assembly. The driving assembly drives the air blocking assembly to move downward, the air holes are exposed, and the gas in the air storage cylinder enters the airbag through the air holes to inflate the airbag. At this time, the increased buoyancy of the airbag is less than the increased gravity of the wastewater in the water collection tank, and the water collection tank slowly moves downward to achieve continuous sampling of wastewater at different depths until the controller receives the signal from the water level sensor, that is, the water quality sampling of a depth interval section in the wastewater tank is completed. Step 3: Control the motor to stop. The wastewater in the water guide pipe is delayed from flowing off. The driving assembly drives the air blocking assembly to reset, closes the air holes, and the air storage cylinder no longer inflates the airbag. At the same time, control the water pump to start. The water pump quantitatively extracts the wastewater in the water collection tank and pumps it into the water quality detector. The water quality detector detects the water quality of the wastewater. After the detection is completed, control the first one-way valve to open, discharge the wastewater in the water collection tank, and the water collection tank moves upward under the action of the airbag to a height higher than the height of the water collection tank before the motor was started in Step 2. Step 4: Repeat Step 2 and Step 3 to complete the sampling and detection of wastewater in different depth interval sections in the wastewater tank. Step 5: When the water collection tank moves to the highest height under the action of the airbag, the exhaust needle is inserted into the valve to deflate the airbag (the second state), and the water collection tank moves downward under the action of gravity to the second preset height. Step 6: Repeat Steps 2 to 5 to achieve continuous detection of wastewater in different depth interval sections in the wastewater tank.

During sampling, the motor drives the second fixed rod to rotate, the second fixed rod drives the first spiral blade to rotate, the first spiral blade lifts the wastewater in the wastewater tank to the water guiding groove, the wastewater in the water guiding groove flows out through the water guiding pipe and impacts the driving assembly, the driving assembly drives the gas blocking assembly to move downward, the air hole is exposed, and the gas in the gas storage cylinder enters the airbag through the air hole to inflate the airbag. At this time, the increased buoyancy of the airbag is less than the increased gravity of the wastewater in the water collection tank, so that during the sampling process, the water collection tank slowly moves downward, and continuous sampling of wastewater in different depth intervals can be realized. After sampling, the water quality of the water sample is detected by a water quality detector arranged on the floating platform to more accurately and comprehensively master the water quality of the wastewater and conduct real-time monitoring of the water quality safety of the chemical industrial park.

[0050] The present invention also provides a monitoring method for a chemical industrial park safety monitoring device, including: Step 1, place the chemical industrial park safety monitoring device at a preset position in the waste water tank. In the initial state, the floating platform floats on the water surface, and the water collection tank is located at a first preset height below the floating platform; Step 2, control the motor to start. The motor drives the connecting rod to rotate, the connecting rod drives the first spiral blade to rotate, and the first spiral blade lifts the waste water in the waste water tank into the water guide groove. The waste water in the water guide groove flows out through the water guide pipe and impacts the driving component. The driving component drives the air blocking component to move downward, the air hole is exposed, and the gas in the air storage cylinder enters the air bag through the air hole to inflate the air bag. At this time, the increased buoyancy of the air bag is less than the increased gravity of the waste water in the water collection tank, and the water collection tank slowly moves downward to continuously sample the waste water at different depths until the controller receives the signal from the water level sensor, that is, the water quality sampling of a depth interval section in the waste water tank is completed; Step 3, control the motor to turn off. The waste water in the water guide pipe is delayed from flowing off. The driving component drives the air blocking component to reset, closes the air hole, and the air storage cylinder no longer inflates the air bag. At the same time, control the water pump to start. The water pump quantitatively extracts the waste water in the water collection tank and pumps it into the water quality detector. The water quality detector detects the water quality of the waste water. After the detection is completed, control the first one-way valve to open, discharge the waste water in the water collection tank, and the water collection tank moves upward under the action of the air bag to a height higher than the height of the water collection tank before the motor is started in Step 2; Step 4, repeat Step 2 and Step 3 to complete the sampling and detection of the waste water at different depth interval sections in the waste water tank; Step 5, when the water collection tank moves to the highest height under the action of the air bag, the exhaust needle is inserted into the air valve to deflate the air bag, and the water collection tank moves downward under the action of gravity to a second preset height; Step 6, repeat Steps 2 to 5 to realize the continuous detection of the waste water at different depth interval sections in the waste water tank.

[0051] Further, in step three, after the detection is completed, according to the detected water quality conditions, the second one-way valve and the third one-way valve on the corresponding chemical agent tank are controlled to open, and at the same time, the air compressor is controlled to open to quantitatively add chemical agents to the wastewater in the detected depth interval section.
