and step 3: when the device reaches a preset position, the first micro motor is controlled to push the detection induction part comprising the containing cavity to move outwards relative to the whole retainer, so that the inlet of the containing cavity is exposed in a sewage environment, the detection inductor starts to work at the moment, the components of the sewage flowing through the detection inductor are detected, the detection result is fed back to the microcomputer, and then the detection result is transmitted back to the control terminal for the reference of researchers;

and 4, step 4: when the detection work is stopped, the containing cavity can be retracted into the retainer under the driving of the first micro motor;

and 5: when the sampling collector is required to collect, the third micro motor is started to push the piston rod to drive the piston and the sampling collector to move outwards, so that the protruding part and the recessed part are separated; when the third micro motor pushes the piston to reach a preset position, the fourth micro motor can be started to drive the sampling collector to rotate so as to realize sampling collection;

2. the monitoring sensing equipment can be hidden, so that the monitoring sensing equipment can resist larger corrosion and prolong the service life;

3. the sewage sample can be freely collected so as to facilitate the subsequent analysis and treatment;

4. alternatively, the flexible chain type sensor can be used for truly and reliably transmitting monitoring data, and is convenient for recovering the detecting head and the sampling collector.

For example, the travelling direction is transmitted to the small steering engine by controlling the microcomputer, so that the steering engine deflects at a preset angle, and the travelling direction is adjusted;

for example, the microcomputer is controlled to control the travelling speed of the intelligent monitoring equipment to enable the intelligent monitoring equipment to travel to a preset position, and the general direction of the intelligent monitoring equipment can be known through the feedback of the position sensor and the depth sensor until the intelligent monitoring equipment moves to the preset position;

and step 3: when a predetermined position is reached, for example, a position with a depth of 25 m, a position with a width of 30 m and a length of 40 m in the wastewater component monitoring pool, the first motor 207 is controlled to push the detection sensing part including the receiving cavity to move outwards (leftwards in the figure) relative to the holder as a whole, as shown in fig. 2, so that the receiving cavity inlet 2053 is exposed in the wastewater environment, wastewater can enter the receiving cavity 2051 through the inlet, and the fine filter 2054 can filter particulate impurities, thereby protecting the detection sensing part 2052 and prolonging the service life thereof; at this time, the detection sensor 2052 starts to work, detects the components of the sewage flowing through it, feeds back the detection result to the microcomputer, and then transmits the detection result back to the control terminal for the reference of researchers;

and 4, step 4: when the detection operation can be stopped, the containing cavity 2051 can be retracted into the holder 203 by the driving of the first micro motor 207;

and 5: when the sampling collector is required to collect, the third micro motor 2082 is started to push the piston rod to drive the piston 2083 and the sampling collector 209 to move outwards (to the right in the figure), so that the protrusion 2095 is separated from the recess 2085; after the third micro-motor pushes the piston 2083 to a predetermined position, the fourth micro-motor 2099 may be activated to rotate the sample collector 209 to collect the sample.

Step 6: when the sampling and collecting are finished, the control terminal sends an instruction to the microcomputer, the microcomputer controls the corresponding equipment, so that the intelligent monitoring equipment 200 floats to the water surface and automatically returns to the initial position, the intelligent monitoring equipment is recovered by the operator through the transportation equipment, and the sample in the sampling collector is taken out.

the treatment mode is various and optional, so that the sewage can be treated in a targeted manner according to the monitoring result, and the treatment effectiveness is improved;

the monitoring and sensing equipment can be hidden, so that the monitoring and sensing equipment can resist larger corrosion and prolong the service life;

the effluent sample can be collected freely for subsequent analysis and treatment;

optionally, with flexible chain sensors, real reliable transmission of monitoring data is possible, as well as facilitating recovery of the probe head and sample collector.
