More specifically, when the balancing weight 302, the sealing plug 311 and the mouth 310 finish sealing the sampling bottle 301, the air valve 309 is located at the same height of the mouth of the sampling bottle 301. When the sampling bottle 301 finishes sampling the water layer with the designated depth and moves upwards, the air supply assembly 5 is started to work through the controller, the air pump in the air supply assembly 5 supplies air with a first pressure value into the traction part 303 through the first pipeline, the upper air valve 309 is opened at the moment, then the air is discharged from the upper air valve 309, and the discharged air floats out of the sample water surface in the form of bubbles and can push away oil stains floating on the water surface in the process of burst. Because the position of the air valve 309 is equal to the bottle opening of the sampling bottle 301, before the sampling bottle 301 discharges water, the air valve 309 can always discharge air bubbles and push away oil stains, so that the surface of a water sample obtained after the sampling bottle 301 discharges water is guaranteed to be free from oil stains, the detection head 202 is not affected by the oil stains when inserted into the sampling bottle 301 for detection, and the accuracy of water quality detection by the detection head 202 is further guaranteed.
Third embodiment
In the process of sampling and measuring the water body, in order to ensure the accuracy of water quality detection in the same water area, multiple points of detection are often required to be carried out on different positions of the water area. The water quality of water bodies at different positions in some water areas is often different due to different pollution or microorganism contents. After finishing the water quality detection at one of the positions, in order to improve the accuracy of the subsequent detection on the water body at the other positions, the detection device needs to be recovered to the shore, and then the detection head 202 and the sampling bottle 301 are cleaned and then the next position is sampled and detected. Therefore, the cleaning workload of operators is increased, the continuity of detection is not possible, and the detection efficiency is reduced.
Therefore, a lower air valve 312 is arranged above the connection part of the traction part 303 and the balancing weight 302, the lower air valve 312 is a one-way valve, and when the balancing weight 302, the sealing plug 311 and the bottle neck 310 finish sealing the sampling bottle 301, the lower air valve 312 is positioned at the lower part of the sampling bottle 301. And the traction part 303 is connected with the cleaning assembly 6 through a second pipeline.
After water quality detection at one detection point is completed, an electromagnet in the electromagnetic area 212 is controlled by a controller to electrify and magnetically adsorb the sampling bottle 301, then a traction motor 304 drives a wind-up roller 305 to rotate, then a traction part 303 is lowered, the traction part 303 pulls a balancing weight 302 to move downwards, the sampling bottle 301 and the balancing weight 302 are separated, water samples reserved in the sampling bottle 301 are discharged outwards, after the water samples are emptied, the traction motor 304 is controlled to drive the wind-up roller 305 to rotate reversely, and finally the traction part 303 drives the balancing weight 302 to move upwards and seal the sealing plug 311 and the bottle mouth 310 to seal the sampling bottle 301. The controller then controls the water pump in the cleaning assembly 6 to supply cleaning fluid having a second pressure value into the traction portion 303 through the second pipeline, and both the upper air valve 309 and the lower air valve 312 are opened, so that the cleaning fluid is introduced into the sampling bottle 301 from the traction portion 303. After a preset amount of cleaning solution is introduced and the sampling bottle 301 is full of the cleaning solution, the cleaning assembly 6 is stopped, then the controller starts the air supply assembly 5 to work, the air pump is controlled to supply air with a second pressure value into the traction portion 303 through the first pipeline, at the moment, the air down valve 312 is opened, the air with the second pressure value enters the sampling bottle 301 to form bubbles, the bubbles are fully mixed with the cleaning solution in the floating process, and the cleaning solution flows to clean the detection head 202 inserted into the sampling bottle 301.
It should be noted that, the second pressure value is greater than the first pressure value, so that when air with the first pressure value is introduced in the second embodiment, the upper air valve 309 may be opened, but the lower air valve 312 may not be opened, so as to prevent air from being discharged from the lower air valve 312 and forming bubbles, and turbulence is generated in the sampling bottle 301 during rising of the bubbles, so as to affect the accuracy of the water sample already collected in the sampling bottle 301.
After the detection head 202 and the sampling bottle 301 are cleaned for a predetermined time, the sampling bottle 301 and the weight 302 may be separated in the same manner as described above, the cleaning liquid in the sampling bottle 301 may be discharged, and then the detection head 202 and the sampling bottle 301 may be cleaned again or multiple times in the same manner as described above. After the detection head 202 and the sampling bottle 301 are cleaned, the device can be used for continuously checking the water quality of the next or a plurality of detection points to be detected, so that the automatic cleaning of the device replaces manual cleaning after a recovery device, the manual cleaning workload is reduced, the next detection point can be directly reached for sampling detection after automatic cleaning, the detection continuity is ensured, and the efficiency of multi-point detection in the same water area is improved.
Finally, it should be noted that: the foregoing description is only illustrative of the preferred embodiments of the present invention, and although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements or changes may be made without departing from the spirit and principles of the present invention.
