[0019] Compared with the prior art, the present application has the following advantages:

[0020] 1、In the present application, the clamping plate is opened, the drainage pipe to be welded is placed in the clamping seat, and one end of the drainage pipe is pushed against the baffle, the drainage pipe is fixed in the clamping seat by rotating the clamping plate, the double-shaft motor is lowered by starting the hydraulic cylinder, the double-shaft motor drives the two side rotating rods and the gear ring to descend synchronously, until the center of the output shaft of the double-shaft motor and the center of the drainage pipe are located on the same horizontal line, the hydraulic cylinder stops working, and then the two side clamping seats are moved in the direction of approaching each other on the manufacturing table by rotating the two side screws, so that the drainage pipes on the clamping seats gradually approach the gear rings, one end of the drainage pipes gradually approaches and presses the inclined surface of the outer scraper block, the outer scraper block slides upward on the rotating rod, and the compression spring one is compressed, until the lower end of the outer scraper block is in close contact with the outer end of the drainage pipe, the outer scraper block stops sliding upward, and as the drainage pipe continues to approach the gear ring, the two side drainage pipes are in close contact with the cleaning disc at one end, the screw is stopped, at this time, the worker holds the water pipe to clean the welding area of the drainage pipe, at the same time, the double-shaft motor is started to drive the two side rotating rods to rotate, the rotating rods drive the two side outer scraper blocks to rotate synchronously, and the outer scraper blocks are closely attached to the outer wall of the drainage pipe under the action of the spring one, so that the outer wall of the welding position of the drainage pipe is conveniently cleaned, the impurity cleaning effect is good, and the welding quality of the welding position is improved.

[0021] 2、In the present application, the cleaning disc is in close contact with the cutting surface at one end of the drainage pipe, when the rotating rod rotates, the gear shaft and the cleaning disc also rotate synchronously, the gear shaft drives the cleaning disc to rotate on the rotating rod under the meshing action of the gear ring, so that the impurities on the welding surface at one end of the drainage pipe can be effectively cleaned, and the subsequent welding quality is also ensured.

[0022] 3、In the present application, when the gear shaft rotates to the lower side of the gear ring along with the rotating rod, the gear shaft also drives the conical top block to move to the lower side of the gear ring synchronously, the conical top block extrudes the front end of the movable plate, pushes the movable plate to slide on the supporting plate in the direction of approaching each other, compresses the spring two and the air bag, the gas in the air bag is sprayed out from the connecting pipe and the spray pipe, the sprayed gas can spray the impurity water after cleaning of the lower part of the drainage pipe welding area to the inside of the drainage pipe, so that the spray cleaning impurity water flowing to the lower welding position of the drainage pipe under the action of gravity can flow to the inside of the drainage pipe, the impurity water remaining in the lower part of the drainage pipe welding area is reduced, and the impurities remaining after drying still adhere to the welding area, which affects the subsequent welding quality.

[0023] 4. In this invention, when the movable plates slide away from each other, the connecting rod will push the nozzle to slide upward on the vertical plate, thereby blowing the residual impurity water into the drain pipe further away, reducing the backflow of impurity water, and also ensuring the cleanliness of the welded area of ​​the drain pipe, thus ensuring the subsequent welding quality.

[0024] 5. In this invention, when the rotating rod rotates, it also drives the inclined groove plate, magnetic plate, and flexible arc panel to rotate synchronously. When the magnetic plate moves to the side close to the magnetic rod, the flexible arc panel moves to the upper side of the inner bottom of the drain pipe. Under the action of magnetic repulsion, it pushes the magnetic plate to slide on the inclined groove plate, compressing the spring three. The flexible arc panel will move obliquely and gradually come into contact with the inner bottom of the drain pipe. It is gradually deformed by the pressure of the bottom of the inner wall of the drain pipe. The flexible arc panel is designed to help sweep the impurity water sprayed by the nozzle to the bottom of the drain pipe into a deeper part of the drain pipe, further reducing the situation of impurity water flowing back to the weld of the drain pipe and ensuring the welding quality of the subsequent drain pipe.

[0025] 6. In this invention, the central trough facilitates the collection of impurity water, reduces the overflow of impurity water from both sides of the flexible arc panel, and improves the sweeping quality of impurity water.

[0026] 7. In this invention, when the outer scraper is squeezed by the drain pipe and adheres to the outer wall of the drain pipe, the outer scraper will rise and compress the spring. At this time, the through groove does not affect the rotation of the cleaning disc and the protrusion. When the outer scraper is not in contact with the drain pipe, the gear shaft drives the cleaning disc to rotate, which will also drive the protrusion to rotate. The protrusion will intermittently hit the outer scraper, causing the outer scraper to shake under the action of the spring. This is beneficial for shaking off the impurities adhering to the outer scraper and improving the cleaning quality of the outer scraper. Attached Figure Description

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0038] Reference Figures 1-6A drainage construction accessory manufacturing device includes a manufacturing table 1. Clamping seats 2 are slidably mounted on both the left and right sides of the upper end of the manufacturing table 1. Clamping plates 3 are rotatably mounted on the upper ends of the clamping seats 2. Baffles 4 are fixedly mounted on the opposite ends of the clamping seats 2. Screws 5 are threadedly mounted on the front side of each clamping seat 2 and rotatably mounted on the manufacturing table 1. A cleaning mechanism is also provided for cleaning impurities from the welding surface of the drainage pipe to be welded on the clamping seats 2. The cleaning mechanism includes a bracket 6 fixedly mounted in the middle of the upper end of the manufacturing table 1. A hydraulic cylinder 7 is fixedly mounted in the middle of the bracket 6. A dual-axis motor 8 is fixedly mounted at the lower end of the hydraulic cylinder 7. Gear rings 9 are symmetrically fixedly mounted on the outer sides of the dual-axis motor 8, with their upper ends meshing. A gear shaft 10 is provided, and a rotating rod 11 is rotatably mounted through one side of the gear shaft 10. The rotating rod 11 is fixedly connected to the output shafts at both ends of the dual-axis motor 8. A cleaning disc 12 is fixedly mounted on the ends of the rotating rod 11 that are far apart from each other. An outer scraper 13 is provided on the upper side of the cleaning disc 12. The ends of the outer scraper 13 that are far apart from each other are inclined surfaces, and the lower ends of the outer scraper 13 are arc surfaces. The ends of the outer scraper 13 that are close to each other are slidably connected to the rotating rod 11. A spring 14 is fixedly mounted on the upper end of the outer scraper 13. The upper end of the spring 14 is fixedly mounted on the rotating rod 11. A through groove 15 is opened on the lower end of the outer scraper 13 corresponding to the cleaning disc 12. A protrusion 16 is fixedly mounted on the outer side of the cleaning disc 12 corresponding to the outer scraper 13.

[0039] During operation, open clamp 3, place the drain pipe to be welded in clamp 2, and push one end of the drain pipe against baffle 4. Rotate clamp 3 to fix the drain pipe in clamp 2. Start hydraulic cylinder 7 to drive dual-axis motor 8 to descend. Dual-axis motor 8 drives rotating rods 11 and gear ring 9 on both sides to descend synchronously until the center of the output shaft of dual-axis motor 8 and the center of drain pipe are on the same horizontal line. Then, stop working. Rotate screws 5 on both sides to drive clamps 2 on both sides to move closer to each other on manufacturing table 1. This makes the drain pipe on clamp 2 gradually approach the gear ring 9 on both sides. One end of the drain pipe will gradually approach and squeeze the inclined surface of outer scraper 13, forcing outer scraper 13 to be pressed against rotating rod 1. 1. The outer scraper 13 slides upwards, compressing spring 14, until the lower end of the outer scraper 13 is in contact with the outer end of the drain pipe. At this point, the outer scraper 13 stops sliding upwards. As the drain pipe continues to approach the gear ring 9, the ends of the two drain pipes that are close to each other will abut against the cleaning disc 12, stopping the rotation of the screw 5. At this time, the worker holds the water spray pipe to clean the welded area of ​​the drain pipe. Simultaneously, the dual-axis motor 8 is started to drive the rotating rods 11 on both sides to rotate. The rotating rods 11 drive the outer scrapers 13 on both sides to rotate synchronously. Under the action of spring 14, the outer scraper 13 is tightly attached to the outer wall of the drain pipe, which facilitates the cleaning of impurities on the outer wall of the welded joint of the drain pipe. The impurity removal effect is good, thus... This improves the welding quality at the weld joint. Simultaneously, because the cleaning disc 12 is in contact with the cut surface of the drain pipe at one end, when the rotating rod 11 rotates, it also drives the gear shaft 10 and the cleaning disc 12 to rotate synchronously. Under the meshing action of the gear ring 9, the gear shaft 10 drives the cleaning disc 12 to rotate on the rotating rod 11, thus effectively cleaning impurities on the weld surface of the drain pipe at the one end, ensuring the subsequent welding quality. When the outer scraper 13 is pressed against the outer wall of the drain pipe by the drain pipe, the outer scraper 13 rises to compress the spring 14. At this time, the through groove 15 does not affect the rotation of the cleaning disc 12 and the protrusion 16. When the outer scraper 13 is not in contact with the drain pipe... When the gear shaft 10 drives the cleaning disc 12 to rotate, it also drives the protrusion 16 to rotate. The protrusion 16 will intermittently hit the outer scraper 13, causing the outer scraper 13 to vibrate under the action of the spring 14. This helps to shake off the impurities adhering to the outer scraper 13 and improve the cleaning quality of the outer scraper 13. After the drain pipe welding joint is cleaned, the screws 5 on both sides are rotated to separate the drain pipes on both sides from the outer scraper 13 and the cleaning disc 12. The hydraulic cylinder 7 is started to drive the dual-shaft motor 8, gear ring 9 and rotating rod 11 to rise synchronously, so that the gear ring 9 and other components rise away from the drain pipes on both sides. Then the screws 5 are rotated to drive the drain pipes on both sides to approach and abut against each other, so that the connection joint of the drain pipes on both sides can be welded.

[0040] As an embodiment of the present invention, a backflow prevention mechanism is also provided to prevent the cleaning sewage at the bottom of the drain pipe from flowing back to the lower side of the welded surface. The backflow prevention mechanism includes a nozzle 17 disposed on one side of the gear ring 9 that is close to each other. The ends of the nozzles 17 that are close to each other are fixedly connected to a connecting pipe 18. The other ends of the connecting pipes 18 are fixedly connected to an airbag 19. The ends of the airbags 19 that are close to each other are fixedly installed with a support plate 20. The ends of the support plates 20 that are far apart from each other are fixedly installed on the gear ring 9. The ends of the airbags 19 that are far apart from each other are fixedly installed with a movable plate 21. The upper end of the movable plate 21 is slidably installed on the support plate 20. A spring 22 is fixedly installed between the movable plate 21 and the support plate 20. The ends of the gear shafts 10 that are close to each other are fixedly installed with a conical top corresponding to the movable plate 21. Block 23, the front end of the movable plate 21 is hinged to the connecting rod 24, the upper end of the connecting rod 24 is hinged to the nozzle 17, the ends of the nozzles 17 that are close to each other are slidably mounted with vertical plates 25, the lower end of the vertical plates 25 is fixedly mounted on the support plate 20, the rotating rods 11 are provided with flexible arc panels 26 on the opposite sides, the opposite ends of the flexible arc panels 26 are provided with concentrated grooves 27, the opposite ends of the flexible arc panels 26 are fixedly mounted with magnetic plates 28, and the gear ring 9 is fixedly mounted with magnetic rods 29 corresponding to the magnetic plates 28, the rear end of the magnetic plates 28 is slidably mounted with inclined groove plates 30, the opposite ends of the inclined groove plates 30 are fixedly mounted on the rotating rods 11, the opposite ends of the magnetic plates 28 are fixedly mounted with springs 31, the other end of the springs 31 is fixedly connected to the inclined groove plates 30;

[0041] During operation, when the gear shaft 10 rotates with the rotating rod 11 to the lower side of the gear ring 9, the gear shaft 10 also drives the conical top block 23 to move synchronously to the lower side of the gear ring 9. The conical top block 23 squeezes the front end of the movable plate 21, pushing the movable plate 21 to slide closer to each other on the support plate 20, compressing the spring 22 and the air bladder 19. The gas in the air bladder 19 is ejected from the connecting pipe 18 and the nozzle 17. The ejected gas can spray the impurities water after cleaning the lower part of the weld area of ​​the drain pipe into the interior of the drain pipe, so that the spray cleaning impurities water flowing to the lower weld area of ​​the drain pipe under the action of gravity can flow into the interior of the drain pipe, reducing the amount of impurities water remaining in the lower part of the weld area of ​​the drain pipe. After drying, the remaining impurities still adhere to the weld area, affecting the subsequent welding quality. When the movable plates 21 slide away from each other, under the action of the connecting rod 24, the nozzle 17 will be pushed to slide upward on the vertical plate 25, thereby blowing the remaining impurities water further into the drain pipe, reducing the amount of impurities. The backflow of water also ensures the cleanliness of the drainage pipe welding area, guaranteeing the subsequent welding quality. When the rotating rod 11 rotates, it also drives the inclined groove plate 30, magnetic plate 28, and flexible arc plate 26 to rotate synchronously. When the magnetic plate 28 moves to the side close to the magnetic rod 29, the flexible arc plate 26 moves to the upper side of the inner bottom of the drainage pipe. Under the action of magnetic repulsion, the magnetic plate 28 is pushed to slide on the inclined groove plate 30, compressing the spring 31. The flexible arc plate 26 will move obliquely and gradually come into contact with the inner bottom of the drainage pipe. It will gradually deform under the pressure of the bottom of the inner wall of the drainage pipe. The flexible arc plate 26 is designed to help sweep the impurity water sprayed by the nozzle 17 to the bottom of the drainage pipe into a deeper part of the drainage pipe, further reducing the backflow of impurity water to the drainage pipe welding point and ensuring the subsequent welding quality of the drainage pipe. The set collection groove 27 facilitates the collection of impurity water, reducing the overflow of impurity water from both sides of the flexible arc plate 26 and improving the sweeping quality of impurity water.

[0042] Working principle:

[0043] In use, the clamping plate 3 is opened, the drain pipe to be welded is placed in the clamping seat 2, and one end of the drain pipe is pushed to abut against the baffle 4. The clamping plate 3 is rotated to fix the drain pipe in the clamping seat 2. The hydraulic cylinder 7 is started to drive the dual-axis motor 8 to descend. The dual-axis motor 8 drives the rotating rods 11 and gear rings 9 on both sides to descend synchronously until the center of the output shaft of the dual-axis motor 8 and the center of the drain pipe are on the same horizontal line. The hydraulic cylinder 7 stops working. Then the screws 5 on both sides are rotated to drive the clamping seats 2 on both sides to move towards each other on the manufacturing table 1. This causes the drain pipe on the clamping seat 2 to gradually approach the gear rings 9 on both sides. One end of the drain pipe will gradually approach and press the inclined surface of the outer scraper 13, forcing the outer scraper 13 to slide upward on the rotating rod 11, compressing the spring 14, until the outer scraper 13 is pressed against the baffle 4. When the lower end of scraper 13 is in contact with the outer end of the drain pipe, scraper 13 stops sliding upward. As the drain pipe continues to approach the toothed ring 9, the ends of the two drain pipes that are close to each other will abut against the cleaning disc 12, stopping the rotation of screw 5. At this time, the worker holds a water spray pipe to clean the welding area of ​​the drain pipe. At the same time, the dual-axis motor 8 is started to drive the rotating rods 11 on both sides to rotate. The rotating rods 11 drive the outer scrapers 13 on both sides to rotate synchronously. Under the action of spring 14, the outer scrapers 13 are tightly attached to the outer wall of the drain pipe, which facilitates the cleaning of impurities on the outer wall of the welded joint of the drain pipe. The impurity removal effect is good, thereby improving the welding quality of the welded joint. At the same time, the cleaning disc 12 abuts against the cut surface of the end of the drain pipe that is close to each other. When the rotating rod 11 rotates, it also drives the gear shaft 10 and the cleaning disc 12 to rotate synchronously. Under the meshing action of the gear ring 9, the gear shaft 10 drives the cleaning disc 12 to rotate on the rotating rod 11, which can effectively clean the impurities on the welding surfaces of the drain pipes that are close to each other, thus ensuring the subsequent welding quality. After cleaning, the staff stops spraying water to clean the welding parts. When the gear shaft 10 rotates with the rotating rod 11 to the lower side of the gear ring 9, the gear shaft 10 also drives the conical top block 23 to move synchronously to the lower side of the gear ring 9. The conical top block 23 squeezes the front end of the movable plate 21, pushing the movable plate 21 to slide closer to each other on the support plate 20, compressing the spring 22 and the air bag 19. The gas in the air bag 19 flows from the connecting The nozzle 18 and spray nozzle 17 spray gas, which can spray the impurities in the lower part of the drainage pipe welding area into the drainage pipe. This allows the sprayed cleaning water that flows towards the lower welding area of ​​the drainage pipe under the action of gravity to flow into the interior of the drainage pipe, reducing the amount of impurities remaining in the lower part of the drainage pipe welding area. Even after drying, residual impurities still adhere to the welding area, affecting the subsequent welding quality. When the movable plates 21 slide away from each other, under the action of the connecting rod 24, the spray nozzle 17 will slide upward on the vertical plate 25, thereby blowing the residual impurities into the drainage pipe further away, reducing the backflow of impurities, and also ensuring the cleanliness of the drainage pipe welding area, ensuring the subsequent welding quality. When the rotating rod 11 rotates...This also causes the inclined groove plate 30, magnetic plate 28, and flexible arc plate 26 to rotate synchronously. When the magnetic plate 28 moves to the side close to the magnetic rod 29, the flexible arc plate 26 moves to the upper side of the inner bottom of the drain pipe. Under the action of magnetic repulsion, the magnetic plate 28 is pushed to slide on the inclined groove plate 30, compressing the spring 31. The flexible arc plate 26 will move obliquely and gradually come into contact with the inner bottom of the drain pipe. It will gradually deform under the pressure of the bottom of the inner wall of the drain pipe. The flexible arc plate 26 is designed to help sweep the impurity water sprayed by the nozzle 17 to the bottom of the drain pipe into a deeper part of the drain pipe, further reducing the situation of impurity water flowing back to the weld of the drain pipe, ensuring the welding quality of the subsequent drain pipe. The set collection groove 27 is convenient for collecting impurity water, reducing the situation of impurity water overflowing from both sides of the flexible arc plate 26, and improving the sweeping quality of impurity water. When the outer scraper 13 is squeezed by the drain pipe When the outer scraper 13 is pressed against the outer wall of the drain pipe, it rises and compresses the spring 14. At this time, the through groove 15 does not affect the rotation of the cleaning disc 12 and the protrusion 16. When the outer scraper 13 is not in contact with the drain pipe, the gear shaft 10 drives the cleaning disc 12 to rotate, which also drives the protrusion 16 to rotate. The protrusion 16 intermittently impacts the outer scraper 13, causing it to vibrate under the action of the spring 14. This helps to shake off impurities adhering to the outer scraper 13, improving the cleaning quality. After the drain pipe welding joint is cleaned, the screws 5 on both sides are rotated to separate the drain pipes on both sides from the outer scraper 13 and the cleaning disc 12. The hydraulic cylinder 7 is activated to drive the dual-shaft motor 8, gear ring 9, and rotating rod 11 to rise synchronously, causing the gear ring 9 and other components to rise away from between the drain pipes on both sides. Then, the screws 5 are rotated again to bring the drain pipes on both sides closer together, allowing for welding at the connection point of the drain pipes on both sides.

[0044] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
