[0002] The rotary cleaning air knife is a device specially designed for efficient cleaning, drying or removal of impurities from the surface of objects. It combines the advantages of traditional cleaning air knives and rotary technology. This type of air knife rotates around an axis and uses high-speed airflow to treat objects in all directions.

[0003] The sewer and canal environment is complex, with many dead corners, and conventional fixed nozzles are difficult to clean thoroughly. When dealing with these complex environments, water or air cannot be effectively delivered to specific dead corners, resulting in poor cleaning effects. In addition, in the dead corners of sewers and canals, plastic bags, paper and other garbage are prone to long-term accumulation due to the lack of water flushing. Plastic bags and other garbage are highly flexible and easily entangled in the internal structure of sewers and canals. Over time, the entangled garbage will continue to accumulate, gradually reducing the water-passing section of the pipe, resulting in poor drainage.

After the angle of the nozzle 102 is adjusted, extend the nozzle body 1 to the cleaning position, and then open the valve on the external air pipe or water pipe. At this time, the gas or liquid is first gathered through the conical tube 104, and then sprayed out through the nozzle 102 for cleaning. The filter 105 can prevent external impurities from entering the nozzle 102.

[0027] like Figure 4 and Figure 5 As shown, it also includes a protective structure 3, the protective structure 3 is installed on the cylindrical tube 101, the protective structure 3 covers the nozzle 102, the protective structure 3 includes a protective cover 301, a connecting ring 302, a concave head 303, a guide rod 304, a convex block 305, a scraper 306, a spring 307, a convex thorn 308 and a stirring rod 39, the protective cover 301 is installed on the cylindrical tube 101, the protective cover 301 covers the nozzle 102, the connecting ring 302 is installed on the cylindrical tube 101, the bottom end of the connecting ring 302 is fixedly connected to the concave head 303, the concave head 303 The outer side of the bottom is a triangular block indented inward, and a guide rod 304 is vertically slidably arranged at the center of the bottom of the protective cover 301. A protrusion 305 is fixedly connected to the top of the guide rod 304, and the convex surface of the protrusion 305 fits the ground of the concave head 303. A scraper 306 is fixedly connected to the bottom end of the guide rod 304, and a spring piece 307 is connected between the scraper 306 and the protective cover 301. The bottom end of the spring piece 307 is rotatably connected to the scraper 306. Protrusions 308 are evenly spaced on the side of the scraper 306, and a mixing rod 39 is rotatably connected to the front and rear sides of the upper part of the scraper 306.

[0028] When cleaning, the protective cover 301 can protect the nozzle 102. When the protective cover 301 is blocked by impurities such as plastic bags, the entire rotating wind knife is pressed downward, the scraper 306 contacts the ground and moves upward, the spring piece 307 is compressed, and the convex block 305 is stuck in the concave head 303. At this time, the rotation of the nozzle 102 drives the concave head 303 to rotate, thereby driving the convex block 305 to rotate, thereby driving the guide rod 304 to rotate, and then driving the scraper 306 to rotate. The scraper 306 rotates to scrape off the impurities on the surface of the protective cover 301. After the protective cover 301 is cleaned, the rotating wind knife is moved upward, the spring piece 307 is reset, and the scraper 306 is driven to move downward and reset. When cleaning the surface of the protective cover 301, the convex thorns 308 can crush the connected impurities. At the same time, the rotation of the scraper 306 drives the crushing rod 39 to rotate, which can prevent external impurities from entering the protective cover 301 during the cleaning process.

[0029] like Figure 6 As shown, a fixed structure 4 is also included. The fixed structure 4 is installed above the nozzle body 1. The fixed structure 4 includes a placement plate 401, a clamping plate 402, a spring 403 and a foot pressure plate 404. The clamping plate 402 is slidably connected to the left side of the top of the placement plate 401, and a spring 403 is connected between the clamping plate 402 and the placement plate 401. The foot pressure plate 404 is rotatably connected to the right side of the top of the placement plate 401, and a torsion spring 403 is connected between the foot pressure plate 404 and the placement plate 401.

[0030] When cleaning places such as sewer pipes, the external pipe can be passed through the placement plate 401 and extended into the sewer pipe. After the external pipe is installed, the clamping plate 402 and the foot pressure plate 404 can be clamped on the external pipe, and then the placement plate 401 is fixed in the installation position, and then the cleaning work can be started. After the cleaning work is completed, the foot pressure plate 404 is stepped on with the foot, so that the foot pressure plate 404 is tilted upward, and the foot pressure plate 404 no longer clamps the external pipe, and then the device can be folded up.

[0031] like Figure 7 and Figure 8 As shown, it also includes a weight-increasing structure 5. The weight-increasing structure 5 is arranged on the outer side of the conical tube 104. The weight-increasing structure 5 includes a mounting ring 501, a lifting plate 502, a convex plate 503, a guide rod 504 and an elastic rope 505. The mounting ring 501 is arranged on the outer side of the conical tube 104. The lifting plate 502 is slidably connected inside the mounting ring 501. The convex plate 503 is fixedly connected to the middle of the lifting plate 502. The convex plate 503 is slidably connected to the conical tube 104 through a waist-shaped hole. The bottom of the lifting plate 502 is connected to the guide rod 504. The guide rod 504 is slidably connected to the mounting ring 501. An elastic rope 505 is connected between the bottom end of the guide rod 504 and the mounting ring 501.

[0032] When airflow or water flow impacts the convex plate 503, the convex plate 503 moves downward under the action of the airflow or water flow impact, thereby driving the guide rod 504 to move downward, and the elastic rope 505 is stretched. At the same time, under the driving force of the convex plate 503, the nozzle body 1 can move downward better. When the injection of airflow or water flow stops, the elastic rope 505 resets and drives the convex plate 503 to move upward and reset.

[0033] like Fig. 9 As shown, it also includes a scraper 6 and a blade 7. The scraper 6 is arranged on the outer side of the cylindrical tube 101, and the outer side of the scraper 6 is in contact with the inner side of the protective cover 301. The top of the cylindrical tube 101 is connected with the blade 7, and the blade 7 is installed at an angle of 45°. When the nozzle 102 rotates, the scraper 6 is driven to rotate, and the scraper 6 rotates to clean the impurities on the inner side of the protective cover 301. At the same time, when the water flow or air flow impacts the blade 7, the blade 7 is at an angle of 45°, so that the nozzle 102 can rotate more evenly under the impact of the water flow or air flow.
