A fluoride ion monitoring device for water quality in pastoral areas

Abstract

The present invention relates to the field of water quality monitoring technology, and in particular to a fluoride ion monitoring device for water quality in pastoral areas. It is difficult for existing equipment to clean the flocculants on the filter screen, resulting in the filter screen's filtering effect on well water being not good enough, which in turn leads to a reduction in the accuracy of the detector's detection results of fluoride ions in well water. Moreover, since the well water level is different at different times, it is difficult for the detector to accurately detect groundwater at various depths. A fluoride ion monitoring device for water quality in pastoral areas includes a mounting frame and a protective shell, etc.; the top of the mounting frame is fixedly connected to the protective shell. The bristles of the cleaning frame will clean the filter plate; the upward movement of the extrusion block will discharge the well water in the detection rod, and the discharged well water will backwash the filter plate, making the filter plate cleaner, and then the clean filter plate can better purify the well water, thereby further improving the accuracy of the detector's detection of well water.

Description

Technical Field

[0001] The present invention relates to the technical field of water quality monitoring, and in particular to a fluoride ion monitoring device for water quality in pastoral areas. Background Art

[0002] The groundwater resources in some pastoral areas of Inner Mongolia have serious problems such as high fluoride ion concentration. Long-term excessive intake of fluoride will cause chronic fluoride poisoning, leading to dental fluorosis and skeletal fluorosis. In severe cases, people will lose their ability to work. It is necessary to monitor the groundwater resources in pastoral areas for a long time to identify the causes of high fluoride ion concentration.

[0003] The existing method is to test the well water by placing a detector into the well. There are solid particles, soft floccules and other impurities in the well water, which will interfere with the detection of the detector. Most of the existing detectors filter the impurities through a filter, and then use bristles to clean the filter. However, soft floccules are easy to stick to the bristles, which can easily cause the floccules to stick to the filter again, which in turn causes the filter to have an insufficient filtering effect on the well water, thereby reducing the accuracy of the detector's fluoride ion detection results in the well water. In addition, since the water level of the well water is different at different times, it is difficult for the detector to accurately detect groundwater at various depths. Summary of the invention

[0039] The cleaning frame 82 is provided with brushes, and the brushes of the cleaning frame 82 are in contact with the outer sides of the two filter plates 71 respectively.

[0040] At first, the protective shell 201 is connected with a rope, and the staff opens the sealing cover on the air inlet end of the air pump 61, and then the staff starts the air pump 61, and the air pump 61 injects air into the airbag 3 to make the airbag 3 inflated, and then the staff turns off the air pump 61 and covers the sealing cover, and finally the staff slowly puts the whole device into the well in the pastoral area through the rope, and after the airbag 3 contacts the water surface in the well, the airbag 3 will float on the water surface with the whole device, and the detection rod 2, the counterweight block 21, the filter plate 71 and the cleaning rack 82 are immersed in the well water, and then the staff remotely starts the electric push rod 5 and the detector 75, and the electric push rod 5 will run intermittently, and the retraction of the telescopic rod of the electric push rod 5 will drive the moving rod 51 to move downward , the moving rod 51 moves downward, which will drive the block 65, the pushing plate 84 and the pushing spring 73 to move. The movement of the pushing spring 73 will push the sliding frame 72 and the squeezing block 74 to move downward. The squeezing block 74 moves downward, which will pump the well water into the through groove of the detection rod 2. When the well water enters the detection rod 2, the impurities will be purified by the filter plate 71, so that the impurities in the well water entering the inside of the detection rod 2 are reduced. The moving rod 51 continues to move downward, which will drive the block 65, the pushing plate 84 and the pushing spring 73 to move. Since the squeezing block 74 contacts the bottom of the through groove of the detection rod 2, the moving rod 51 continues to move, which compresses the pushing spring 73. The pushing plate 84 continues to move downward, which will push the sliding cylinder 81 to move downward.

After the detection is completed, the extension of the telescopic rod of the electric push rod 5 will drive the moving rod 51, the block 65 and the pushing plate 84 to move upward, and the upward movement of the pushing plate 84 will cause the sliding cylinder 81 to reset upward driven by the tension spring 83, and the upward resetting of the sliding cylinder 81 will drive the cleaning frame 82 to move upward, and the upward movement of the cleaning frame 82 will be The filter plate 71 is cleaned in another direction. The upward movement of the moving rod 51 will reset the pushing spring 73. The moving rod 51 continues to move upward and drives the squeezing block 74 to move upward through the pushing spring 73. The upward movement of the squeezing block 74 will discharge the well water in the detection rod 2.

At the same time, the block 65 will drive the contact plate 63 in contact with the block 65 to move upward. The upward movement of the contact plate 63 will contact the contact switch 64. After the contact plate 63 contacts the contact switch 64, the solenoid valve 62 will be opened for a period of time.The air in the airbag 3 will be discharged through the electromagnetic valve 62 and the exhaust valve 202. After a period of time, the electromagnetic valve 62 is closed, and the air in the airbag 3 is no longer discharged. The contact plate 63 stops moving after contacting the contact switch 64. The block 65 continues to move upward and disengages from the contact plate 63, so that the contact plate 63 moves downward under the action of gravity, and the contact plate 63 disengages from the contact switch 64. After the moving rod 51, the block 65, the sliding frame 72, the pushing spring 73, the squeezing block 74, the sliding cylinder 81, the cleaning frame 82, the tension spring 83 and the pushing plate 84 are reset, the electric push rod 5 stops moving, the air in the airbag 3 is reduced, so that the buoyancy of the airbag 3 is reduced, and the reduction of the buoyancy of the airbag 3 will cause the entire device to move downward.

The lower pressing frame 96 is reset upward driven by the reset spring 95. The upward reset of the lower pressing frame 96 causes the rotating ring 931, the rotating frame 93, the movable frame 92 and the barbed rod 921 to rotate. The rotation of the barbed rod 921 gathers the bristles of the cleaning frame 82 together. At the same time, the cleaning frame 82 moves upward, and the flocculation on the bristles of the cleaning frame 82 is hooked by the barbs of the barbed rod 921, making the bristles of the cleaning frame 82 cleaner. The clean cleaning frame 82 can clean the filter plate 71 more cleanly, thereby making the filter plate 71 better able to purify the well water, thereby further improving the accuracy of the detector 75 in detecting the well water. After the lower pressing frame 96, the rotating ring 931, the rotating frame 93, the movable frame 92 and the barbed rod 921 are reset, the process repeats like this.

After the solenoid valve 62 is closed, no air will be discharged through the air guide frame 101, the diverter frame 102 and the one-way valve 104. The upward movement of the extrusion block 74 will push the diverter frame 102 and the one-way valve 104 to move upward, and the upward movement of the diverter frame 102 will compress the compression spring 103, and then repeat this process.
