[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-7 As shown, the pipe inner wall anti-corrosion coating thermal spraying device includes a thermal spraying equipment body 1 and a pipe rotating machine 2 used in conjunction with it. An extension pipe 3 is installed on one side of the thermal spraying equipment body 1, and the other end of the extension pipe 3 is connected to a nozzle 4. A fixing block 5 is fixedly connected to one side of the bottom of the extension pipe 3. A support pipe 6 is fixedly connected inside the fixing block 5. The other end of the support pipe 6 extends to one side of the fixing block 5 and is fixedly connected to a fixing long block 9. An extension plate 8 is fixedly connected to one side of the bottom of the support pipe 6. Guide wheels 7 are fixedly connected to the upper and lower sides of one side of the fixing long block 9 and the top of the extension plate 8. When the operator rotates the winding reel 147, the guide wheels 7 can guide the rope 148. A protective cover 13 is fixedly connected to the surface of the support pipe 6. A shielding structure 11 and a drive mechanism used in conjunction with the support pipe 6 are provided on the surface of the support pipe 6. The moving structure 12 and the shielding structure 11 include several square blocks 111 fixedly connected to the surface of the support pipe 6. A slider 112 is slidably connected inside the square block 111. A protrusion 113 is fixedly connected to the surface of one side of the square block 111. A groove 114 is opened on one side of the square block 111. A slider 115 is slidably connected to the inner wall of the groove 114. One end of the slider 115 is fixedly connected to the slider 112. A folded fireproof cloth 116 is provided on one side of the slider 112. When the staff cleans the inner wall of the pipe, the staff can pull the slider 115 and move the slider 112. At this time, the folded fireproof cloth 116 will also unfold. In this way, the staff can adjust the folded fireproof cloth 116 according to the diameter of the inner wall of the pipe, thereby preventing dust from falling onto the nozzle 4 and affecting the normal use of the nozzle 4.

[0025] The drive structure 12 includes a gear disk 121 rotatably connected to the surface of the support tube 6. A rotating rod 122 is rotatably connected to one side of the protrusion 113. A gear 123 is fixedly connected to the surface of the rotating rod 122. The gear 123 meshes with the gear disk 121. The gear 123 and the gear disk 121 are located inside the protective cover 13. A first handwheel 124 is fixedly connected to the other end of the rotating rod 122. Several arc-shaped grooves 125 are opened inside the gear disk 121. The inside of the arc-shaped grooves 125 cooperates with the slide rod 115. When the operator rotates the first handwheel 124, it can drive the rotating rod 122 and the gear 123 to rotate together, and make the gear disk 121 rotate. When the gear disk 121 rotates, it can make the slide rod 115 move in the arc-shaped grooves 125, and drive the slider 112 to move. This makes it easier for the operator to unfold the folded fireproof cloth 116. The fixed long block 9 is equipped with a cleaning structure 14 and a dust suction structure 15 used in conjunction with it.

[0026] The cleaning structure 14 includes a movable block 141 slidably connected above and below the fixed long block 9. One end of the movable block 141 is fixedly connected to an arc-shaped scraper 142. Springs 143 are installed both above and below the interior of the fixed long block 9. The two ends of the springs 143 are fixedly connected to the inner wall of the fixed long block 9 and the other end of the movable block 141, respectively. Through grooves 144 are opened on both the upper and lower sides of one side of the fixed long block 9. A sliding plate 145 is slidably connected to the inner wall of the through groove 144. The sliding plate 145 is fixedly connected to one end of the movable block 141. A movable rod 146 is rotatably connected to the surface of the thermal spraying equipment body 1. A winding reel 147 is fixedly connected to the surface of the movable rod 146. A rope 148 is wound around the surface of the winding reel 147. The other end of the rope 148 is fixedly connected to one side of the sliding plate 145. A second handwheel 149 is fixedly connected to the other end of the movable rod 146. Before the worker performs thermal spraying on the inner wall of the pipe, the worker first... The operator needs to turn the second handwheel 149 to unwind the take-up reel 147 and release the tension on the slide plate 145. At this time, the compressed spring 143 can push the two moving blocks 141, the arc scraper 142 and the slide plate 145 to move through its own elastic force. Thus, the operator can adjust the position of the arc scraper 142 according to the diameter of the pipe. Then, when the operator starts the thermal spraying equipment body 1 to process the inner wall of the pipe, the arc scraper 142 can scrape and clean the inner wall of the pipe. The dust collection structure 15 includes a dust collection pipe 153 fixedly connected inside the support pipe 6. Both sides of the surface of the dust collection pipe 153 are connected to the air pipe 151, and the air pipe 151 is a retractable hose. The other end of the air pipe 151 extends to the outside of the support pipe 6 and is fixedly connected to the dust collection port 152. One side of the dust collection port 152 is fixedly connected to the other side of the slide plate 145.

[0027] When the operator adjusts the position of the arc-shaped scraper 142, the movement of the moving block 141 causes the sliding plate 145 and the suction port 152 to move together. After moving to the designated position, the operator starts the thermal spraying equipment body 1 to process the inner wall of the pipe. At this time, the arc-shaped scraper 142 cleans the inner wall of the pipe, generating dust and other impurities. Then, the operator needs to start the vacuuming equipment connected to the other end of the suction pipe 153. Subsequently, the dust scraped off by the arc-shaped scraper 142 is sucked in through the suction port 152 and finally discharged through the vent pipe 151 and the suction pipe 153. This prevents the dust scraped off by the arc-shaped scraper 142 from re-adhering to the inner wall of the pipe. A fixing structure 10 is provided on both the surface of the thermal spraying equipment body 1 and one side of the protective cover 13. The fixing structure 10 includes a connecting plate 101 fixedly connected to the surface of the thermal spraying equipment body 1 and one side of the protective cover 13. A fixing pin 102 slides through the inside of the connecting plate 101. Several circular grooves 103 are opened on the surfaces of the rotating rod 122 and the movable rod 146. The other end of the fixing pin 102 passes through one side of the connecting plate 101 and is used to cooperate with the inside of the circular groove 103. When the first handwheel 124 and the second handwheel 149 are rotated, the operator can pass the fixing pin 102 through one side of the connecting plate 101 and insert it into the circular groove 103, so as to limit and fix the first handwheel 124 and the second handwheel 149 after rotation.

[0028] Working principle: Before applying thermal spraying to the inner wall of the pipe, the operator first needs to pull out the fixing pin 102 inside the movable rod 146 to release the limit on the second handwheel 149. Then, the operator needs to turn the second handwheel 149 to unwind the reel 147 and release the tension on the slide plate 145. At this time, the compressed spring 143, through its own elastic force, can push the two moving blocks 141, the arc-shaped scraper 142, the slide plate 145, and the suction port 152 to move, so that the operator can move according to the pipe's direction. The diameter is adjusted to change the position of the arc-shaped scraper 142 and the suction port 152. After adjustment, the worker needs to reinsert the fixing pin 102 into the circular groove 103 to limit and fix it. Then, the worker needs to pull out the fixing pin 102 in the rotating rod 122 to release the limit of the first handwheel 124. Then, the worker needs to rotate the first handwheel 124. When the first handwheel 124 rotates, it can drive the rotating rod 122 and the gear 123 to rotate together, and make the gear plate 121 rotate. When the gear plate 121 rotates... When rotated, the slide bar 115 moves within the arc-shaped groove 125, simultaneously moving the slider 112. This allows the operator to unfold the folded fireproof cloth 116 according to the diameter of the pipe's inner wall. After unfolding, the operator needs to reinsert the fixing pin 102 into the circular groove 103 to limit the first handwheel 124. Then, the operator starts the thermal spraying equipment body 1 to process the inner wall of the pipe, while simultaneously starting the vacuum cleaner connected to the other end of the suction pipe 153. This allows the arc-shaped scraper 142 to clean the inner wall of the pipe. The dust is scraped and cleaned, and the suction port 152 can suck up the scraped dust, which is then discharged through the vent pipe 151 and the suction pipe 153. The unfolded folded fireproof cloth 116 can cover the floating dust and prevent the dust from falling onto the nozzle 4 and affecting normal use. After the inner wall of the pipe is processed, the operator needs to repeat the above operation, pull the arc-shaped scraper 142 with the rope 148 and move it to the starting position to prevent damage to the inner wall of the pipe that has been sprayed when the thermal spraying equipment body 1 moves back to the starting position.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
