Detailed implementation manners

[0025] Please refer to Figures 1-6 , an embodiment provided by the present invention: a water turbine anti-corrosion layer spraying device. The spraying machine 01, servo motor 31, and nut pair 36 used in this application are all products that can be directly purchased on the market. Their principles and connection methods are all prior arts well-known to those skilled in the art, so they will not be elaborated here.

[0026] Comprising: a spraying machine 01, and a reciprocating spraying adjustment assembly 02 is arranged at the robotic arm end of the spraying machine 01;

[0027] The reciprocating spraying adjustment assembly 02 includes a support plate 21 and a cushion block 30. A sleeve rod 22 penetrates through the inside of one end of the support plate 21. When the sleeve rod 22 rotates left and right reciprocally, it can drive the spray head in the middle of the sleeve rod 22 to rotate left and right reciprocally, enabling large-area spraying on the water turbine. A spray head is fixedly installed in the middle of the sleeve rod 22. A small gear 23 is fixedly arranged on the outer wall of one end of the sleeve rod 22. When the first toothed plate 24 moves left and right reciprocally along the guide rod 26, it can drive the small gear 23 and the sleeve rod 22 to rotate left and right reciprocally, and then drive the spray head in the middle of the sleeve rod 22 to rotate left and right reciprocally. One end of the first toothed plate 24 is fixedly connected to a second toothed plate 25. The guide rod 26 penetrates through the inside of the first toothed plate 24 and the second toothed plate 25, and the guide rod 26 plays a role in supporting and guiding the first toothed plate 24 and the second toothed plate 25. A half gear 27 is engaged with the outer wall of the second toothed plate 25. During the process of the half gear 27 rotating left and right reciprocally around the central rod 28, it can cause the second toothed plate 25 to move left and right reciprocally along the guide rod 26, and then drive the first toothed plate 24 to move left and right reciprocally along the guide rod 26. A central rod 28 penetrates through the upper part of the half gear 27. A fixed rod 29 is fixedly arranged above the half gear 27. The fixed rod 29 can drive the half gear 27 to rotate around the central rod 28, and then drive the second toothed plate 25 and the first toothed plate 24 to move left and right reciprocally along the guide rod 26. A servo motor 31 is fixedly installed above the cushion block 30. The output end of the servo motor 31 is fixedly connected to a driving rod 32. A turntable 33 is fixedly connected to the outer wall of one end of the driving rod 32. The turntable 33 does not affect the rotation of the lead screw 34. When the lead screw 34 rotates, it can drive the nut pair 36 and the moving rod 37 to move, thereby changing the angle at which the fixed rod 29 rotates around the central rod 28, and finally changing the spraying range of the spray head. A lead screw 34 is inserted into the turntable 33. A handle 35 is fixedly installed at one end of the lead screw 34. During the process of rotating the handle 35, the handle 35 drives the lead screw 34 to rotate. The rotation of the lead screw 34 drives the nut pair 36 to move. The outer wall of the lead screw 34 is connected to the nut pair 36. The nut pair 36 drives the moving rod 37 to move inside the turntable 33, adjusting the distance between the moving rod 37 and the central axis of the turntable 33, and the angle at which the fixed rod 29 rotates around the central rod 28 can be adjusted. The outer wall of the nut pair 36 is fixedly provided with a moving rod 37. During the process of the moving rod 37 rotating around the driving rod 32 following the turntable 33, it can drive the fixed rod 29 to rotate left and right reciprocally around the central rod 28, realizing the left and right reciprocal rotation of the half gear 27 around the central rod 28, and then driving the first toothed plate 24 and the second toothed plate 25 to move left and right reciprocally along the guide rod 26, and finally driving the small gear 23 and the sleeve rod 22 to rotate left and right reciprocally.

[0028] Furthermore, the support plate 21 is fixedly connected to the robotic arm of the spraying machine 01 to ensure the firmness of the position of the support plate 21. The sleeve rod 22 is rotatably connected to the support plate 21 to ensure that the support plate 21 does not affect the rotation of the sleeve rod 22. When the sleeve rod 22 rotates back and forth left and right, it can drive the spray head in the middle of the sleeve rod 22 to rotate back and forth left and right, enabling large-area spraying of the water turbine.

[0029] Furthermore, both the first toothed plate 24 and the second toothed plate 25 are slidably connected to the guide rod 26. The guide rod 26 plays a role in supporting and guiding the first toothed plate 24 and the second toothed plate 25. When the first toothed plate 24 moves back and forth left and right along the guide rod 26, it can drive the small gear 23 and the sleeve rod 22 to rotate back and forth left and right, and then drive the spray head in the middle of the sleeve rod 22 to rotate back and forth left and right.

[0030] Furthermore, one end of the guide rod 26 is fixedly connected to the spraying machine 01 to ensure the firmness of the position of the guide rod 26. The guide rod 26 plays a role in supporting and guiding the first toothed plate 24 and the second toothed plate 25. During the process of the half gear 27 rotating back and forth left and right around the central rod 28, it can cause the second toothed plate 25 to move back and forth left and right along the guide rod 26, and then drive the first toothed plate 24 to move back and forth left and right along the guide rod 26.

[0031] Furthermore, the central rod 28 is fixedly connected to the spraying machine 01 to ensure the firmness of the position of the central rod 28. The fixing rod 29 can drive the half gear 27 to rotate around the central rod 28, and then drive the second toothed plate 25 and the first toothed plate 24 to move back and forth left and right along the guide rod 26. The cushion block 30 is fixedly connected to the support plate 21 to ensure the firmness of the position of the cushion block 30. The cushion block 30 plays a role in supporting and limiting the servo motor 31.

[0032] Furthermore, the lead screw 34 is rotatably connected to the turntable 33. The turntable 33 does not affect the rotation of the lead screw 34. The rotation of the lead screw 34 can drive the nut pair 36 and the moving rod 37 to move, thereby changing the angle of rotation of the fixing rod 29 around the central rod 28, and ultimately changing the spraying range of the spray head.

[0033] Furthermore, the moving rod 37 is slidably connected to the turntable 33. During the process of rotating the handle 35, the handle 35 drives the lead screw 34 to rotate. The rotation of the lead screw 34 drives the nut pair 36 to move. The nut pair 36 drives the moving rod 37 to move within the turntable 33. By adjusting the distance between the moving rod 37 and the central axis of the turntable 33, the angle of rotation of the fixing rod 29 around the central rod 28 can be adjusted.

[0034] Further, the moving rod 37 is located inside the fixed rod 29 and is movably connected to the fixed rod 29. When the moving rod 37 rotates around the driving rod 32 following the turntable 33, it can drive the fixed rod 29 to rotate left and right reciprocally around the central rod 28, enabling the semi-gear 27 to rotate left and right reciprocally around the central rod 28. Further, it drives the first toothed plate 24 and the second toothed plate 25 to move left and right reciprocally along the guide rod 26, and finally drives the pinion 23 and the sleeve rod 22 to rotate left and right reciprocally.

[0035] Working principle: During use, first, according to the diameter of the water turbine, rotate the handle 35. The handle 35 drives the lead screw 34 to rotate within the turntable 33. The lead screw 34 drives the nut pair 36 and the moving rod 37 to move, adjusting the distance between the moving rod 37 and the central axis of the driving rod 32. When the moving rod 37 subsequently drives the fixed rod 29 to rotate left and right reciprocally around the central rod 28, the angle of the semi-gear 27 rotating left and right reciprocally around the central rod 28 can be adjusted. Further, the distance of the second toothed plate 25 and the first toothed plate 24 moving left and right reciprocally along the guide rod 26 can be adjusted, enabling the spraying range of the nozzle to be adjusted. Fix the water turbine on the rotating mechanism of the spraying machine 01, with the nozzle located above the water turbine. Start the servo motor 31. The output end of the servo motor 31 drives the driving rod 32 to rotate. The driving rod 32 drives the turntable 33 to rotate. During the rotation of the moving rod 37 inside the turntable 33, it can drive the fixed rod 29 to rotate left and right reciprocally around the central rod 28. The fixed rod 29 drives the semi-gear 27 to rotate left and right reciprocally around the central rod 28. The semi-gear 27 drives the second toothed plate 25 to move left and right reciprocally. The second toothed plate 25 drives the first toothed plate 24 to move left and right reciprocally along the guide rod 26. The first toothed plate 24 drives the pinion 23 to rotate left and right reciprocally. The pinion 23 drives the sleeve rod 22 inside the wall to rotate left and right reciprocally, further driving the nozzle to rotate left and right reciprocally. The nozzle can reciprocally rotate to spray the water turbine below.
