Description

Technical Field

[0001] This utility model belongs to the field of pipeline anti-corrosion technology, specifically a spraying device for anti-corrosion coating of water supply pipelines. Background Technology

[0002] Water supply pipelines, as the main arteries of urban operation, are essential basic facilities for the normal life of urban residents. To better utilize space, water supply pipelines are usually buried underground. Therefore, before burial, anti-corrosion spraying treatment is required to extend the service life of the pipelines. According to the patent document with authorization announcement number CN223159448U, entitled "A Water Supply Pipeline Anti-corrosion Agent Spraying Device," it specifically includes: a main body; the top of the main body is interconnected, and a through pipe is installed inside the top of the main body. Two sealed bearings are installed outside the through pipe, located inside the main body; two spraying pipes are connected to the outside of the through pipe, and flexible hoses are connected to the outer ends of the spraying pipes, with the flexible hoses connected to the through pipe; retaining rings are fixedly installed on opposite sides of the outside of the main body, one retaining ring contacting the sealed bearings, and the other retaining ring contacting the through pipe; a motor is fixedly installed outside the main body, and a synchronous belt is connected to the outside of the motor, with the synchronous belt connected to the through pipe; however, the following defects still exist: This method involves directly spraying anti-corrosion coating onto the water supply pipes, neglecting the critical issue that dust easily adheres to the outer surface of the pipes during storage, transportation, or pretreatment. This dust forms an isolation layer between the pipe surface and the anti-corrosion coating, preventing the coating from adhering tightly to the pipe substrate. This not only reduces the adhesion of the coating but also makes it prone to blistering, cracking, or even peeling, severely affecting the anti-corrosion effect, shortening the actual service life of the pipes, and increasing subsequent maintenance costs.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0015] Example 1, by Figure 1 The present invention relates to an anti-corrosion coating spraying device for water supply pipelines, including a through pipe 1, and a cleaning mechanism 2 and a spraying mechanism 3 provided on the outside of the through pipe 1.

[0016] Specifically, by Figure 2-3 The cleaning mechanism 2 includes an outer ring 201 fixedly sleeved on the outside of the tube 1. Four guide posts 207 are fixedly connected at equal angles to the outer side of the outer ring 201. Guide plates 206 are movably sleeved on the outer side of the guide posts 207. Springs 2010 are fixedly connected between the guide plates 206 and the outer ring 201, and are sleeved on the outer side of the guide posts 207. Supports 205 are fixedly connected to the sides of the two guide plates 206 on the upper and lower sides that are close to each other. Arc-shaped brushes 204 are provided on the inner sides of the two supports 205. Two... Each guide plate 206 has a bracket 202 fixedly connected to one side of each other. The inner side of each bracket 202 is provided with an arc-shaped brush 203. The two brackets 202 are located between the two brackets 205 and the through pipe 1. The outer side of the guide post 207 is provided with a groove 208. The inner side of the guide plate 206 is fixedly connected with a slider 209. The slider 209 is slidably connected to the groove 208. By setting the slider 209, the guide plate 206 is limited to ensure the stability of the guide plate 206 when sliding along the guide post 207. In use, the water supply pipe is first passed between two curved brushes 204 and two curved brushes 203, and the water supply pipe passes through the through pipe 1. During this process, the two supports 205 move away from each other, and the two supports 202 move away from each other, causing each guide plate 206 to slide along each guide post 207. At this time, each spring 2010 is stretched, so that the two curved brushes 204 and two curved brushes 203 are tightly attached to the water supply pipe under the action of the elastic force of each spring 2010, removing the dust on the outer surface of the water supply pipe and finally improving the spraying effect.

[0017] Specifically, by Figure 4-5The spraying mechanism 3 includes a hollow ring 301 located outside the through pipe 1. Two spray nozzles 3013 are symmetrically fixedly connected to the outer side of the hollow ring 301. An inlet pipe 302 is fixedly connected to the outer circumference of the hollow ring 301. Two limiting rings 3014 are fixedly sleeved on the outer side of the through pipe 1. The hollow ring 301 is located between the two limiting rings 3014. Multiple limiting rollers 3015 are rotatably connected between the two limiting rings 3014 at equal angles. Each limiting roller 3015 is connected to the hollow ring 301. The inner wall abuts against the two limiting rings 3014, and multiple side rods 3016 are fixedly connected at equal angles on the side of the two limiting rings 3014 that are close to each other. One end of each side rod 3016 is provided with a ball 3017 that abuts against the hollow ring 301. By setting the limiting roller 3015, the side rods 3016, and the ball 3017, the hollow ring 301 is supported and limited, so that the hollow ring 301 can only rotate. A support plate 305 is fixedly installed on the outer side of the through pipe 1, and a support plate 305 is fixedly installed on the outer side of the support plate 305. A drive motor 306 is provided, and a drive shaft 307 is fixedly connected to the drive motor 306. A side cylinder 303 located below the drive shaft 307 is fixedly connected to the outer side of the hollow ring 301. A large gear 304 is fixedly installed on the outer side of the side cylinder 303. A small gear 308 is fixedly installed on the outer side of the drive shaft 307. The small gear 308 meshes with the large gear 304. Two L-shaped plates 309 are symmetrically fixedly connected to the outer side of the hollow ring 301. Electric push rods are fixedly installed on both L-shaped plates 309. 3010, each of the two electric push rods 3010 has a sleeve block 3012 fixedly connected to its output end. The two sleeve blocks 3012 are respectively fixedly sleeved on the outside of the two nozzles 3013. The two sleeve blocks 3012 are respectively fixedly connected to the side that is far away from each other. The two limit rods 3011 pass through the two L-shaped plates 309 respectively. Through the cooperation between the limit rods 3011 and the L-shaped plates 309, the sleeve block 3012 is limited to ensure the stability of the sleeve block 3012 when it moves. In operation, the anti-corrosion coating is first introduced into the hollow ring 301 through the inlet pipe 302 by the booster pump, so that the anti-corrosion coating is sprayed onto the surface of the water supply pipeline from the two spray nozzles 3013. When the two electric push rods 3010 are started, they drive the two sleeve blocks 3012 to move, and drive the two spray nozzles 3013 to move. The distance between the two spray nozzles 3013 is adjusted according to the size of the water supply pipeline. When the drive motor 306 is started, it drives the drive shaft 307 to rotate, and drives the pinion 308 to rotate. Since the pinion 308 meshes with the large gear 304, the hollow ring 301 is driven to rotate through the side cylinder 303, realizing the circumferential rotation of the two spray nozzles 3013, and finally uniformly spraying the water supply pipeline.
