by arranging the limiting ball 53 between the protective soft wheel 26 and the arc stress rod 5, when the pressure plate 51 is extruded, the arc stress rod 5 moves towards the protective soft wheel 26 and simultaneously moves between the arc stress rod 5 and the protective soft wheel 26, when the inclination amplitude of the arc stress rod 5 is overlarge, the limiting ball 53 is extruded between the elastic sheet 52 and the arc stress rod 5, at the moment, the arc stress rod 5 cannot continuously incline, and further, the limiting ball 53 limits the arc stress rod 5, so that the problem that the outer ring of the protective soft wheel 26 is damaged due to the fact that the pressure plate 51 and the air bag 4 are pressed too low is solved; the wavy groove 6 is formed in the pressure receiving plate 51, the arc-shaped spring 61 is fixedly connected in the pressure receiving plate 51, so that the friction force between the pressure receiving plate 51 and the air bag 4 can be increased when the pressure receiving plate 51 is extruded by the air bag 4, the outer rings of the air bag 4 and the protective soft wheel 26 can be extruded into an uneven shape, the problem of sliding displacement of the pressure receiving plate 51 in the air bag 4 can be avoided, meanwhile, the friction force between the protective soft wheel 26 and a pipeline can be increased, and the sliding is reduced; when the spray head 2 sprays the spraying liquid, part of the spraying liquid can be sprayed out from the emission port 21 on the side wall of the spray head 2, and meanwhile, the air guide plate 7 which is obliquely arranged is arranged in the emission port 21, so that the sprayed air flow and the spraying liquid can impact the pipeline wall, the spraying liquid sprayed out from the emission port 21 can be sprayed onto the pipeline, and the waste of the spraying liquid is reduced; when air flows in the emission port 21, the air flow impacts the arc-shaped air receiving piece 81, the sliding block 8 slides on the top of the air guide plate 7 at the moment, the elastic pull rope 82 is stretched, then the sliding block 8 pushes the roadster 85 on the arc-shaped guide groove 84 through the transmission rod 83, and at the moment, the drainage piece 71 can be straightened, the arrangement can ensure that spraying liquid sprayed out of the emission port 21 is sprayed near the spray head 2 when the flow rate of the air flow in the emission port 21 is low, the drainage piece 71 is straightened when the flow rate of the air flow in the emission port 21 is high, so that the air flow sprayed out of the emission port 21 is blown farther, and the problem that the spraying liquid near the spray head 2 is sprayed unevenly due to too much spraying liquid brought out by the air flow is avoided; a pressure reducing port 9 is formed in the drainage sheet 71; the decompression opening 9 is provided with a plurality of groups in the drainage sheet 71.
The use method of the spraying device for repairing the pipeline is suitable for the spraying device for repairing the pipeline and comprises the following steps:
s1: firstly, uniformly shaking the spraying liquid, heating the spraying liquid to 30-35 ℃, then pouring the spraying liquid into the spraying equipment 1, and horizontally placing the spraying equipment 1;
s2: aligning the port of the spraying device 1 to the wall of the pipeline in step S1, pressing the spraying device 1 to make the protective soft wheel 26 at the end of the nozzle 2 tightly pressed on the side wall of the pipeline, and opening the switch inside the spraying device 1 to spray the spraying liquid inside the spraying device onto the pipeline from 11;
s3: and (4) standing the sprayed pipeline of S2 in a cool and ventilated place to keep the temperature near the sprayed pipeline at 10-25 ℃, and standing for 3 days to obtain the repaired pipeline.
