Specifically, the air floatation scraping device in the prior art is a water treatment device which is characterized in that air bubbles are introduced into water to enable air to be attached to suspended particles in the form of micro-bubbles so as to enable the density of the air to be smaller than that of the water, the air bubbles float on the water surface by utilizing the buoyancy principle, and solid-liquid separation is realized, when the air floatation scraping device is used, the water inlet 21 is connected with a sewage discharge port, so that sewage enters the reaction zone 2 from the water inlet 21, then a coagulant is added into the reaction zone 2, when the sewage completely floods the stirrer 22, the stirrer 22 is started to rotate and stir, so that the sewage fully contacts with the coagulant, and the hydrophilicity of the suspended particles in the sewage is changed through the action of the coagulant, the fine particles in the sewage are flocculated into larger flocculates, at the moment, the air bar string 31 is started, the air bar string 31 is used for generating bubbles at the bottom of the contact area 3, the bubbles are attached to the flocculated suspended matters, the overall density of the suspended matters with a large amount of attached bubbles is smaller than that of water, the flocculates and the bubbles rise to the liquid level together to form scum, the effect of solid-liquid separation is realized, then the chain 42 is started to rotate, the chain 42 drives the scraper 44 to move through the fixed column 43, the scraper 44 is contacted with the scum on the liquid level when moving, thereby carrying the scum to move towards the waste slag pool 5, finally the scum is scraped into the waste slag pool 5, and because the number of the scrapers 44 is several, after one scraper 44 scrapes the dross to the waste slag pool 5, other scrapers 44 scrape the regenerated dross later, so that the cyclic scraping of the dross is realized; however, some air floatation scraping devices are arranged outdoors, if the device suddenly rains during working, rainwater enters the contact area 3, so that the water level inside the contact area 3 rises, and finally the scum overflows, and because the outdoor air floatation device occupies a larger area, the cost is very high if the rain shielding device is arranged, and the environment requirement is not high when the air floatation device works, in order to solve the problem of rising of the water level, operators need to plug the water inlet 21 first, avoid continuous waste water entering from the inside of the device, then increase the rotation speed of the chain 42, accelerate the scum scraping speed of the scraping plate 44, and adjust the height of the partition plate between the scum pool 5 and the contact area 3 according to the water level, Therefore, the scum in the equipment is rapidly processed, but if the rain potential is too large, the water level line in the contact area 3 can be rapidly raised, and finally the liquid can be caused to overflow the scraper 44, and the scraper 44 is not only contacted with the scum, but also contacted with the liquid, so that the scraper 44 can be subjected to resistance of the liquid when the scum is scraped, the kinetic energy of the scraper 44 in movement can be greatly increased, and a large amount of liquid which has been subjected to solid-liquid separation can be scraped into the waste slag pool 5, thereby causing resource waste; therefore, the scraping structure 4 is arranged in the scraping plate 44, when the solid-liquid separation of the wastewater is realized, the chain 42 is started to rotate, the chain 42 moves together with the scraping plate 44, at the moment, the telescopic plate 601 in the initial state is arranged in the scraping plate 44, so that the telescopic plate 601 contacts with the scum, the scraping plate 44 is not used for scraping the scum, the scum is scraped into the scum pool 5, when the water level is continuously raised during the rain, at the moment, the telescopic plate 601 is required to be stretched, the rotating rod 602 is rotated when the rotation of the chain 42 is reset, the universal joint 604 is driven to rotate by the rotating rod 602 in the rotating process, The universal joint 604 will drive the screw 605 at the other end to rotate, because the screw 605 is in threaded connection with the expansion plate 601, and the limiting blocks 609 at the two ends of the expansion plate 601 slide in the sliding grooves 608, the expansion plate 601 at the moment will move downwards, finally before the water level rises to exceed the expansion plate 601, the expansion plate 601 will move into the scraper 44 and will not contact with the scum, because the length of the plate for scraping the scum is shortened at the moment, the scraper 44 will contact with the scum, because the chain 42 at the moment has accelerated rotation, and the resistance of liquid to the scraper 44 will be reduced when the scum is scraped by the scraper 44, So that scum can be scraped as soon as possible; Through setting up adjusting device 6, can adjust the length of scraper blade 44 when the rain leads to the inside water line of contact zone 3 to rise, and then can not contact each other with liquid again when scraper blade 44 fully scrapes the dross, can just accomplish the scraping of dross before the dross overflows equipment.
As shown in fig. 1 to 9, the adjusting device 6 further includes: the gear 603, the gear 603 is arranged on the arc surface of one end of the rotating rod 602, and the gear 603 extends to one side of the scraping frame 41; a displacement rack 611, the displacement rack 611 slides on one side of the scraping frame 41, and the displacement rack 611 is engaged with the gear 603; a telescopic cylinder 626, the telescopic cylinder 626 being provided at the lower end of the displacement rack 611.
Specifically, if the device is raining during operation, and the water line is continuously rising, at this time, the water line in the contact area 3 can be observed, if the liquid is about to cross the scraper 44, the telescopic cylinder 626 needs to be started, the telescopic cylinder 626 will push the displacement rack 611 upwards, finally when the chain 42 drives the scraper 44 to move, the gear 603 of the arc surface of the rotating rod 602 is meshed with the displacement rack 611, so that the gear 603 rotates, the rotating rod 602 is driven to rotate together through the rotation of the gear 603, and finally the telescopic plate 601 moves to the inside of the scraper 44, so that the scraper 44 is contacted with the scum again.
As shown in fig. 5 to 6, the universal joint 604 rotates inside the squeegee 44, and the universal joint 604 is initially placed obliquely, and the size of the universal joint 604 near one end of the screw 605 is smaller than the size of the universal joint 604 near one end of the rotation lever 602.
Specifically, when the expansion plate 601 needs to retract into the scraper 44, the rotation of the rotating rod 602 drives the screw 605, and the universal joint 604 is obliquely arranged, and the size of the universal joint 604 near one end of the screw 605 is smaller than that near one end of the rotating rod 602, so that the design can change the rotating direction and realize the axial adjustment effect.
As shown in fig. 8 to 9, two ends of the limiting block 609 are rotatably connected with auxiliary rollers 610, and the auxiliary rollers 610 slide on the inner wall of the sliding groove 608.
Specifically, after the waste residues of the expansion plate 601 are scraped, the scraping plate 44 needs to be driven to reset through the chain 42, the scraping plate 44 at this time is turned over, and when the expansion plate 601 is turned over during raining, rainwater easily flows into the scraping plate 44 during the turning process and remains in the sliding groove 608, and finally the limiting block 609 is not smooth in the sliding groove 608, and the friction force between the limiting block 609 and the sliding groove 608 can be reduced by arranging the auxiliary roller 610, so that the limiting block 609 is in the sliding groove 608, and the limiting block 609 can be smooth in sliding despite the accumulated water in the sliding groove 608.
As shown in fig. 5 to 7, the upper end of the squeegee 44 is rotatably connected with a brush 606, the brush 606 is attached to the surface of the expansion plate 601, both ends of the brush 606 are provided with coil springs 607, and one end of the coil springs 607 is connected with the squeegee 44.
Specifically, when the expansion plate 601 moves toward the inside of the scraping plate 44, the brush 606 will abut against the surface of the expansion plate 601, and the elastic force is released by the coil spring 607, so that the brush 606 will brush the scum remained on the surface of the expansion plate 601, and the scum is prevented from moving to the inside of the scraping plate 44 through the expansion plate 601.

Specifically, by arranging the starting frame 612 on the side wall of the base frame 1 and arranging the horizontal pipeline 614 which is communicated with the contact area 3 in the starting frame 612, when the horizontal line in the contact area 3 rises, the horizontal line in the starting frame 612 is consistent with the contact area 3 through the horizontal pipeline 614, as the sensor 613 in the starting frame 612 is the water immersion sensor 613, when the sensor 613 is in a normal state, the insulating layer between the electrode and the circuit can prevent the current from flowing, and when the water level exceeds a certain threshold value, the liquid is in contact with the electrode to form a conductive path, the current in the sensor 613 starts to flow, and when the horizontal line rises to a certain height, the sensor 613 can transmit a signal to the telescopic cylinder 626, so that the telescopic cylinder 626 is started, and the telescopic plate 601 is automatically moved to the inside of the scraper 44 according to the height of the water level.
As shown in fig. 11, the horizontal duct 614 is provided inside with a scum screen 615, and the scum screen 615 is provided near one end of the contact area 3.
Specifically, by providing the dross filter 615, it is possible to prevent the dross in the contact area 3 from entering the inside of the start-up frame 612 through the horizontal pipe 614 when the inside of the contact area 3 is lifted horizontally, thereby causing unnecessary cleaning work.
As shown in fig. 10 to 12, a fixed ring 616 is disposed in the horizontal pipe 614, one end of the horizontal pipe 614, far from the scum filter screen 615, is slidably connected with a movable plate 617, and the movable plate 617 is not in contact with the inner wall of the horizontal pipe 614 in the initial state, one end of the movable plate 617 is fixedly connected with a sliding rod 618, the sliding rod 618 slides on the inner wall of the fixed ring 616, the other end of the movable plate 617 is provided with a fixed frame 619, a connecting ring 620 is disposed in the fixed frame 619, the lower end of the connecting ring 620 is fixedly connected with a connecting arm 622, one end of the connecting arm 622, close to the connecting ring 620, is rotatably connected with a rotating shaft 621, both ends of the rotating shaft 621 are fixedly connected in the inner portion of the starting frame 612, the other end of the connecting arm 622 is provided with a floating ball 623, and the density of the floating ball 623 is smaller than water.
Specifically, when the water level in the contact area 3 rises due to rain, water enters the inside of the starting frame 612 through the horizontal pipe 614, when the water level in the starting frame 612 rises, the floating ball 623 also moves upwards, and when the floating ball 623 rises, the connecting arm 622 turns around the rotating shaft 621 as the center of the circle, so that the connecting ring 620 is driven to move towards the horizontal pipe 614, and the connecting ring 620 is connected with the fixed frame 619, and the fixed frame 619 is integrated with the movable plate 617, so that the movable plate 617 moves towards the horizontal pipe 614 and finally is attached to the inner wall of the horizontal pipe 614, and when the floating ball 623 rises to the top, the movable plate 617 completely blocks the horizontal pipe 614 and does not enter the water source again, and at the moment, the water level exceeds the threshold value of the sensor 613, and the sensor 613 transmits a signal towards the telescopic cylinder; since the water line may still be raining after the scum scraping is completed, the water level line is still rising, and finally overflows the device, by isolating the starting frame 612 from the contact area 3, the water inside the starting frame 612 can be a separate water source and is still water, so that the unstable signal receiving of the sensor 613 is avoided, and the starting of the telescopic cylinder 626 is not timely caused.
