[0033] like Figure 3 and Figure 4As shown, the painting mechanism 2 includes a delivery pump 201, a paint spraying pipe 202, an extraction pipe 203, a storage tank 204, a drain hole 205, a solenoid valve 206, a threaded column 207, an arc-shaped plate 208, a stabilizer bar 209, and a rotating assembly 210. The delivery pump 201 is located on one side of the pipe body 1, the paint spraying pipe 202 is located at the output end of the delivery pump 201, and the paint spraying pipe 202 is arranged in an H-shape. The extraction pipe 203 is located at the input end of the delivery pump 201, and the storage tank 204 is fixedly connected to... Connected to one end of the extraction tube 203, multiple drain holes 205 are opened inside the paint spray tube 202, and the multiple drain holes 205 are arranged opposite to each other. The solenoid valve 206 is located on one side of the paint spray tube 202. The threaded column 207 is threadedly connected to the inside of the tube body 1. The arc plate 208 is rotatably connected to the top of the threaded column 207. Two stabilizing rods 209 are fixedly connected to the bottom of the arc plate 208. One end of the stabilizing rod 209 extends to the outer wall of the tube body 1 and is slidably connected to the tube body 1. External paint is injected into storage tank 204; the pipe can be sent into the pipe body 1 by rotating component 210 and rotated for adjustment; rotating threaded column 207 causes arc plate 208 to rise or fall along the length of stabilizer bar 209, which can support the bottom of the pipe inside pipe body 1; starting delivery pump 201 can extract paint from storage tank 204 through extraction pipe 203, and after passing through spray pipe 202, it is sprayed out from drain hole 205; while solenoid valve 206 is normally closed, the paint flows in spray pipe 202 and sprays the outer wall of the pipe; after opening solenoid valve 206, the paint can spray the inner wall of the pipe; thus improving work efficiency.

[0034] like Figure 3As shown, the rotating assembly 210 includes a support block 2101, a support frame 2102, a slide groove 2103, a servo motor 2104, a lead screw 2105, a moving block 2106, a limiting plate 2107, a first motor 2108, a rotating plate 2109, a limiting block 2110, and a support rod 2111. The support frame 2102 is fixedly connected to the top of the tube body 1 and to the side of the support block 2101 away from the tube body 1. The slide groove 2103 is formed inside the support block 2101. The servo motor 2104 is bolted to one side of the support frame 2102, and the lead screw 2105 is coaxially arranged on the servo motor. At the output end of machine 2104, a moving block 2106 is threadedly connected to the outer wall of lead screw 2105, and the moving block 2106 is slidably connected to the inside of slide groove 2103. A limiting plate 2107 is fixedly connected to the bottom of the moving block 2106. A first motor 2108 is bolted to the side of the limiting plate 2107 away from the tube body 1. A rotating plate 2109 is coaxially arranged at the output end of the first motor 2108. A limiting block 2110 is bolted to the side of the rotating plate 2109 close to the tube body 1. A support rod 2111 is fixedly connected between the tube body 1 and the support frame 2102. The limiting plate 2107 is slidably connected to the outer wall of the support rod 2111. One end of the pipe is attached to the limiting block 2110, and the inner wall of the pipe is locked onto the outer wall of the limiting block 2110. Since the limiting block 2110 is bolted to the rotating plate 2109, it is easy for the user to replace it according to the diameter of the pipe hole. The servo motor 2104 is started, causing the lead screw 2105 to rotate, which in turn drives the moving block 2106 to slide in the slide groove 2103, thereby causing the limiting plate 2107 to move along the length of the support rod 2111, so that the limiting plate 2107 is attached to the pipe body 1, making it easy for the user to send the pipe into the pipe body 1. When the painting work is carried out, the first motor 2108 is started, causing the rotating plate 2109 and the limiting block 2110 to rotate, which in turn drives the pipe on the limiting block 2110 to rotate, so that the pipe receives the sprayed paint more evenly.

[0035] like Figure 5 As shown, the support assembly 3 includes a partition plate 301, a fixing plate 302, an adjusting groove 303, an electric push rod 304, and an adjusting block 305. The partition plate 301 is fixedly connected to the inner wall of the pipe body 1. Two fixing plates 302 are fixedly connected to one side of the partition plate 301. Two adjusting grooves 303 are formed inside the partition plate 301. Two electric push rods 304 are respectively disposed on one side of the two fixing plates 302. Two adjusting blocks 305 are respectively disposed on one side of the two electric push rods 304, and the adjusting blocks 305 are slidably connected to the inner wall of the adjusting groove 303. After the pipe enters the pipe body 1, the electric push rod 304 can be activated to slide the adjusting block 305 in the adjusting groove 303, causing one side of the adjusting block 305 to fit against the outer wall of the pipe, thus improving the stability of the pipe inside the pipe body 1.

[0036] likeFigure 4 As shown, an arc-shaped groove 4 is provided on one side of the adjusting block 305, and a first placement groove 5 is provided on one side of the arc-shaped groove 4. A first stabilizing roller 6 is rotatably connected to the inner wall of the first placement groove 5. The arc-shaped groove 4 can better fit the outer wall of the pipe; while the first stabilizing roller 6 in the first placement groove 5 can increase the smoothness of the pipe when rotating.

[0037] like Figure 4 As shown, a second placement groove 7 is provided on one side of the arc-shaped plate 208, and a second stabilizing roller 8 is rotatably connected to the inner wall of the second placement groove 7. When the arc-shaped plate 208 lifts the pipe, the second stabilizing roller 8 in the second placement groove 7 will directly contact the outer wall of the pipe, facilitating the rotation of the pipe.

[0038] like Figure 5 As shown, multiple extension rods 9 are fixedly connected to the side of the adjusting block 305 away from the arc groove 4. One end of the extension rod 9 extends to the outside of the tube body 1 and is slidably connected to the tube body 1. When the adjusting block 305 moves, the extension rods 9 move synchronously inside the tube body 1, increasing the stability of the adjusting block 305 during movement.

[0039] like Figure 3 As shown, a second motor 10 is fixedly connected to the top of the storage tank 204. A rotating column 11 is coaxially arranged at the output end of the second motor 10, and multiple stirring blades 12 are fixedly connected to the outer wall of the rotating column 11. When the second motor 10 is started, the rotating column 11 and the stirring blades 12 rotate, which can stir the paint in the storage tank 204 and prevent the paint in the storage tank 204 from solidifying.

[0040] Specifically, when using the painting equipment for water conservancy pipelines: one end of the pipeline is attached to the limiting block 2110, and the inner wall of the pipeline is locked onto the outer wall of the limiting block 2110; since the limiting block 2110 is bolted to the rotating plate 2109, it is easy for the user to replace it according to the diameter of the pipeline hole; the servo motor 2104 is started, causing the lead screw 2105 to rotate, which in turn drives the moving block 2106 to slide in the slide groove 2103, so that the limiting plate 2107 moves to the pipe body 1 and sends the pipeline into the pipe body 1; external paint is injected into the storage tank 204, and the second motor 10 is started, causing the rotating column 11 and the stirring blade 12 to rotate, stirring the paint and preventing the paint from solidifying; after the pipeline enters the pipe body 1, the threaded column 207 is rotated, so that the arc plate 208 rises or falls to support the pipe; the electric push rod 304 is activated, causing the adjusting block 305 to slide in the adjusting groove 303, so that the first stabilizing roller 6 in the first placement groove 5 comes into contact with the outer wall of the pipe for clamping; the delivery pump 201 is activated, which can draw the paint from the storage tank 204 through the extraction pipe 203, and after passing through the paint spraying pipe 202, it is sprayed out from the drain hole 205; the solenoid valve 206 is normally closed, and the paint flows in the paint spraying pipe 202 to spray the outer wall of the pipe; after the solenoid valve 206 is opened, the paint can spray the inner wall of the pipe; the first motor 2108 is activated, causing the rotating plate 2109 and the limiting block 2110 to rotate, which in turn drives the pipe on the limiting block 2110 to rotate, so that the pipe receives the sprayed paint more evenly.

[0041] All technical features in this embodiment can be freely combined according to actual needs.

[0042] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
