The movable seat 12 drives the electric brush roller 141 to move to be exactly corresponding to the hole of the steel. Then the telescopic rod of the cylinder 13 extends to drive the electric brush roller 141 to move downward through the movable seat 12, so that the electric brush roller 141 rotates to apply the anticorrosive coating in the hole of the steel.

[0030] Please refer to Figure 3 As shown in the figure, the driving component includes a screw rod 10 and a servo motor 101. The screw rod 10 is horizontally rotatably connected to the guide frame 9. The screw rod 10 is threadedly connected to the slider 11. The servo motor 101 is installed on the right side of the outer surface of the guide frame 9. The output shaft of the servo motor 101 is driven by a synchronous belt component between the right side of the screw rod 10.

[0031] Please refer to Figure 5 andFigure 6 As shown, the cleaning component includes a jet pipe 15, a cylinder block 151, a one-way corrugated pipe 152, a piston rod 153, a trigger component and a one-way intake pipe 156. The front side of the moving part of the double-axis moving machine 7 is fixedly connected with a jet pipe 15. The jet end of the jet pipe 15 faces the front guide roller 3. The bottom of the jet pipe 15 is symmetrically connected with one-way corrugated pipes 152 on the left and right. The front side of the top of the base 1 is symmetrically and fixedly connected with cylinder blocks 151 on the left and right. The cylinder blocks 151 on the left and right are respectively connected and communicated with the intake ends of the one-way corrugated pipes 152 on the left and right. The piston rods 153 are slidably connected to the inner sides of the cylinder blocks 151 on the left and right. The top of the cylinder blocks 151 on the left and right are both communicated with one-way intake pipes 156. A trigger component is arranged between the piston rod 153 and the end of the front guide roller 3. When the trigger component operates, the trigger component can drive the piston rod 153 to move. The trigger component includes a movable plate 154 and a reciprocating lead screw 155. The reciprocating lead screws 155 are symmetrically and rotatably connected to the upper part of the front side of the base 1 on the left and right. The end parts of the reciprocating lead screws 155 on the left and right that are close to each other are respectively fixedly connected to the left and right ends of the third guide roller 3 from the front to the back in the front. The end parts of the piston rods 153 on the left and right that are far away from each other are both fixedly connected with movable plates 154. The movable plates 154 on the left and right are respectively threadedly connected to the reciprocating lead screws 155 on the left and right. When the movable plate 154 moves, the movable plate 154 can drive the piston rod 153 to move.

[0032] When the anti-corrosion treatment of the steel of the cooling tower is required, this device can be used. The shape of the steel is square bar-shaped. Initially, the charging bucket 5 contains an appropriate amount of anti-corrosion coating. The anti-corrosion coating in the charging bucket 5 is blocked by the electric control valve 52 when it is discharged into the material guiding pipe 51. Subsequently, the steel is moved to contact the inclined surface of the front guiding seat 2, and the steel is pushed backward by an external machine for feeding. When the steel moves backward and contacts the front guiding roller 3, the front guiding roller 3 guides the backward movement of the steel. The backward movement of the steel drives the front guiding roller 3 to rotate forward. The forward rotation of the front guiding roller 3 drives the reciprocating lead screw 155 to rotate forward. The forward rotation of the reciprocating lead screw 155 drives the movable plate 154 to move left and right. The movable plate 154 drives the piston rod 153 to move left and right. When the piston rods 153 on both sides move towards each other, the piston rods 153 push the air in the cylinder block 151 into the one-way corrugated pipe 152. The air in the one-way corrugated pipe 152 is discharged into the air spraying pipe 15. The air spraying pipe 15 sprays the air on the steel, and the air blows off the dust and impurities attached to the steel. When the piston rods 153 on both sides move away from each other and reset, the piston rods 153 draw the external air into the cylinder block 151 through the one-way air inlet pipe 156. Repeating this way, the air can be sprayed out to remove the dust and impurities on the steel. When the steel after removing the dust and impurities moves backward to the base 1, the operation of the external machine is stopped, the steel stops moving backward, the steel is separated from the front guiding roller 3, the front guiding roller 3 stops rotating forward, the front guiding roller 3 stops driving the reciprocating lead screw 155 to rotate forward, the reciprocating lead screw 155 stops driving the movable plate 154 to move, and the air spraying pipe 15 stops spraying air. Thus, whenever the steel moves to the base 1, the air spraying pipe 15 completely stops spraying air. Then, start the double-axis moving machine 7 to drive the frame 6 to move downward. The frame 6 drives the brush plate 8 to move downward. When the brush plate 8 moves downward and contacts the inner wall of the steel, stop the double-axis moving machine 7. Then start the electric control valve 52. The anti-corrosion coating in the charging bucket 5 is discharged into the brush plate 8 through the material guiding pipe 51, so that the anti-corrosion coating adheres to the bristles of the brush plate 8. Then start the double-axis moving machine 7 to drive the frame 6 to move back and forth. The frame 6 drives the brush plate 8 to move back and forth. The brush plate 8 moves back and forth to apply the anti-corrosion coating on the inner wall of the steel. The anti-corrosion coating can form a dense protective film on the surface of the steel, effectively isolating the direct contact between the steel and the corrosive medium, thereby slowing down or preventing the occurrence of corrosion. At the same time, the forward and backward movement of the frame 6 also drives the guiding frame 9 to move back and forth. The guiding frame 9 drives the cylinder 13 to move back and forth through the slider 11. The cylinder 13 drives the material control pipe 14 to move back and forth through the movable seat 12. When the inner wall of the steel is coated, stop the double-axis moving machine 7, and the brush plate 8 and the material control pipe 14 stop moving back and forth. Close the electric control valve 52. Start the double-axis moving machine 7 again to move, so that the electric brush roller 141 moves back and forth to be horizontally corresponding to the hole of one of the steels. Then start the servo motor 101. The servo motor 101 drives the screw rod 10 to rotate through the synchronous belt assembly. The rotation of the screw rod 10 drives the slider 11 to move left and right.The slider 11 moves left and right. The cylinder 13 and the movable seat 12 drive the electric brush roller 141 to move left and right until it is exactly corresponding to the hole of the steel. The left and right movement of the electric brush roller 141 drives the material control pipe 14 to move left and right. The left and right movement of the material control pipe 14 drives the rotating shaft 142 to rotate. Under the action of the torsion spring 143, the material control pipe 14 can be retracted and released to prevent the material control pipe 14 from loosening and affecting the movement of the slider 11. Turn off the servo motor 101, and then start the cylinder 13. The telescopic rod of the cylinder 13 extends to drive the movable seat 12 to move downward. The movable seat 12 drives the electric brush roller 141 to move downward. The electric brush roller 141 moves downward into the hole of the steel. Turn off the cylinder 13 and start the material control pipe 14. The anticorrosive coating in the guide pipe 51 is discharged into the material control pipe 14. The anticorrosive coating in the material control pipe 14 is discharged into the electric brush roller 141. Start the electric brush roller 141 to rotate. The electric brush roller 141 rotates to apply the anticorrosive coating to the hole of the steel, completing the anticorrosive treatment of the hole of the steel. Then, the telescopic rod of the cylinder 13 shortens to drive the electric brush roller 141 to move upward and reset through the movable seat 12. The electric brush roller 141 is moved to directly above the hole of the next steel through the double-axis moving machine 7. By following the above operations, the anticorrosive coating can be applied to the hole of the steel again. Repeating this process continuously, the holes on the steel can be sprayed with the anticorrosive coating. When the anticorrosive treatment of all the holes of the steel is completed, turn off the double-axis moving machine 7, and the electric brush roller 141 stops moving. Turn off the electric brush roller 141 and start the double-axis moving machine 7 to drive the frame 6 to move upward and reset. The frame 6 drives the brush plate 8 to move upward and reset, and at the same time, the electric brush roller 141 is driven to move upward and reset. Then, the steel is pushed backward by an external machine to complete discharging through the rear guide roller 3, and the anticorrosive coating on the inner wall and in the holes of the steel is dried. When the anticorrosive coating on the inner wall and in the holes of the steel is dry, turn the outer wall of the steel upward, and follow the above operations to load the material again for the anticorrosive treatment of the outer wall of the steel. Then, push the next steel to move onto the base 1 to complete the application of the anticorrosive coating. In this way, through the action of the brush plate 8 and the electric brush roller 141, the anticorrosive treatment of the inner wall and holes of the steel can be completed, and the anticorrosion is more comprehensive, thus improving the safety of the steel in use.

[0033] Please refer to Figure 7 and Figure 8As shown in the figure, the painting device for the anti-corrosion of cooling tower steel also includes a scraping component installed between the guiding frame 9 and the movable seat 12. The scraping component includes a scraping frame 16, a collecting frame 161, connecting springs 162 and guiding rods 163. Two guiding rods 163 are embedded and slidably connected to the rear side of the slider 11. A scraping frame 16 is fixedly connected between the rear ends of the two guiding rods 163. The upper part of the scraping frame 16 is a slope. The slope of the scraping frame 16 contacts the movable seat 12. The scraping frame 16 contacts the electric brush roller 141. When the electric brush roller 141 rotates, the scraping frame 16 can scrape off the residual anti-corrosion paint on the electric brush roller 141. Two connecting springs 162 are connected between the front side of the scraping frame 16 and the rear side of the slider 11. The two connecting springs 162 are respectively sleeved on the two guiding rods 163. The collecting frame 161 is snap-connected to the bottom of the guiding frame 9. The collecting frame 161 is located below the scraping frame 16. When the anti-corrosion paint on the scraping frame 16 drops, the collecting frame 161 can collect and process the anti-corrosion paint.

[0034] Please refer to Figure 9 As shown in the figure, the painting device for the anti-corrosion of cooling tower steel also includes a clamping component installed between the base 1 and the double-shaft moving machine 7. The clamping component includes a fixing plate 17, guiding rods 171, clamping plates 172, return springs 173 and pulling wires 174. Fixing plates 17 are fixedly connected symmetrically left and right at the top of the base 1. Guiding rods 171 are slidably inserted through the front and rear of the left and right fixing plates 17 symmetrically. A clamping plate 172 is fixedly connected between the inner ends of the front and rear guiding rods 171. When the clamping plate 172 moves and contacts the steel, the clamping plate 172 can clamp and fix the steel. Return springs 173 are symmetrically connected between the mutually separated ends of the left and right guiding rods 171 and the mutually separated sides of the left and right fixing plates 17 respectively. Pulling wires 174 are symmetrically connected to the left and right of the double-shaft moving machine 7. The tails of the left and right pulling wires 174 respectively slide through the left and right fixing plates 17 and are fixedly connected to the left and right clamping plates 172.

[0035] When the telescopic rod of the cylinder 13 extends, the telescopic rod of the cylinder 13 drives the movable seat 12 to move downward. Since the upper part of the scraping frame 16 is inclined, the downward movement of the movable seat 12 drives the scraping frame 16 to move forward, and the connecting spring 162 is compressed. The scraping frame 16 moves forward and disengages from the electric brush roller 141. When the movable seat 12 drives the electric brush roller 141 to move upward and reset, the movable seat 12 resets and stops limiting the scraping frame 16. Due to the action of the connecting spring 162, the scraping frame 16 moves backward and resets to contact the electric brush roller 141. The scraping frame 16 scrapes off the residual anticorrosive paint on the electric brush roller 141. Since the scraping frame 16 is vertically arranged, the anticorrosive paint on the scraping frame 16 drops downward into the collection frame 161 for collection. When the collection frame 161 contains an appropriate amount of anticorrosive paint, the collection frame 161 is removed from the guiding frame 9 for reusing the anticorrosive paint. After all the anticorrosive paint is poured out, the collection frame 161 is snapped back onto the guiding frame 9. In this way, it can prevent the waste caused by the residual anticorrosive paint on the electric brush roller 141, thus ensuring the full utilization of the anticorrosive paint.

[0036] Initially, the reset spring 173 is in a stretched state. When the double-axis moving machine 7 moves downward and drives the frame 6 to move downward, the frame 6 drives the brush plate 8 to move downward. At the same time, the double-axis moving machine 7 also drives the pull wire 174 to move downward, and the pull wire 174 is relaxed. Due to the action of the reset spring 173, the left and right guide rods 171 move towards each other, and the left and right guide rods 171 drive the left and right clamping plates 172 to move towards each other. The left and right clamping plates 172 move and contact the steel, and the left and right clamping plates 172 clamp and fix the steel. Subsequently, the brush plate 8 continues to move downward and contacts the clamped steel, and then the anticorrosive paint can be applied to the clamped steel to complete the anticorrosion treatment. When the anticorrosion treatment of the steel is completed, the double-axis moving machine 7 is started to move upward and reset, so that the brush plate 8 moves upward and disengages from the steel. The upward movement and reset of the double-axis moving machine 7 drive the pull wire 174 to move upward. The upward movement of the pull wire 174 drives the left and right clamping plates 172 to move away from each other and reset through the fixed plate 17. The left and right clamping plates 172 drive the left and right guide rods 171 to move away from each other and reset, and the reset spring 173 is stretched. The left and right clamping plates 172 reset and loosen the steel. In this way, it can prevent the movement of the steel from affecting the painting, thus improving the stability of the steel during painting.

[0037] Please refer to Figure 10 As shown, the painting device for the anticorrosion of the cooling tower steel also includes an electric roller 18. The electric rollers 18 are rotatably connected at the middle of the top of the base 1 at equal intervals. When the steel moves and contacts the electric roller 18, the electric roller 18 can drive the steel to move backward for guiding and conveying.

[0038] When the steel moves backward onto the base 1, the steel contacts the electric roller 18. Start the electric roller 18 to rotate forward. The forward rotation of the electric roller 18 drives the steel to move backward, thus guiding and conveying the steel. In this way, the frictional force of the contact between the steel and the base 1 can be reduced, making the backward movement of the steel smoother.

[0039] Finally, it is necessary to note that the above content is only used to help understand the technical solution of the present invention and should not be construed as a limitation on the protection scope of the present invention; any non-essential improvements and adjustments made by those skilled in the art based on the above content of the present invention shall fall within the scope of protection required by the present invention.
