Description

Technical Field

[0001] This utility model relates to the technical field of anti-corrosion spraying devices, and in particular to an anti-corrosion spraying device for cable sleeve surfaces. Background Technology

[0002] As a key component protecting cable joints in power transmission systems, cable sleeves are exposed to damp outdoor or underground environments for extended periods, making them highly susceptible to corrosion. This can lead to surface rust, reduced structural strength, and in severe cases, power outages. Therefore, surface anti-corrosion spraying is the core process for extending the service life of cable sleeves, and the performance of the spraying equipment directly determines the uniformity, adhesion strength, and protective effect of the anti-corrosion layer.

[0003] Existing anti-corrosion spraying devices for cable sleeves mostly employ a manual spraying mode with fixed nozzles. For cable sleeves of varying diameters (φ50-φ300mm) and lengths (200-1000mm), it is difficult to ensure uniform coverage of the anti-corrosion coating. Coating thickness deviations can reach 50-100μm, with localized missed spraying rates exceeding 8%, leading to rust spots appearing on the sleeves after only 1-2 years of service. Furthermore, while some automated devices are equipped with rotating mechanisms, the clamping and positioning are unstable, with radial runout of the sleeve exceeding 2mm during rotation, further exacerbating uneven spraying. The pass rate for anti-corrosion layer adhesion tests is less than 85%. Therefore, these technical problems need to be addressed. Utility Model Content

[0022] In this invention, the cleaning mechanism includes a second bolt rod 16 rotatably mounted inside the device housing 2. A first servo motor 6 is mounted on one outer wall of the device housing 2. The output end of the first servo motor 6 passes through the device housing 2 and is coaxially fixed to one end of the second bolt rod 16. A second scraper 21 is threadedly connected to the second bolt rod 16. One end of the second scraper 21 is tightly fitted to the inner bottom surface of the device housing 2. Through the second bolt rod 16, the first servo motor 6, and the second scraper 21, residual paint on the inner bottom surface of the device housing 2 is easily cleaned. The drying mechanism includes a protective cover 13 fixedly mounted on the inner wall of the device housing 2. Multiple heating tubes 17 are equidistantly installed on the inner side of the protective cover 13. Through the device housing 2... The inner wall protective cover 13 and heating tube 17 facilitate the drying of the coated cable sleeve; the scraping mechanism includes a guide rod 15 horizontally fixed to the upper end of the protective cover 13, a first bolt rod 11 rotatably mounted on the upper end of the guide rod 15, a second servo motor 7 mounted on the device housing 2 at one end of the first bolt rod 11, the output end of the second servo motor 7 passing through the device housing 2 and coaxially fixed to one end of the first bolt rod 11, a first scraper 14 slidably mounted on the first bolt rod 11 and the guide rod 15, the first scraper 14 closely fitting the surface of the protective cover 13, and through the guide rod 15, the first bolt rod 11, the second servo motor 7 and the first scraper 14, it is easy to clean the paint residue on the surface of the protective cover 13.

[0023] Working Principle: In use of this invention, firstly, the self-locking structure of the closed door 3 is unlocked, opening the closed door 3 and exposing the rotating cylinder 22 inside the outer casing 2. Then, the cable sleeve is fitted onto the fixing rod 10 around the rotating cylinder 22. The limiting ball 18 pops outward under the action of the telescopic spring 19, fixing the cable sleeve from the inside to prevent it from shaking during spraying. Depending on the sleeve size, a suitable fixing rod 10 can be selected for installation to ensure the sleeve is stable. The closed door 3 is closed and the self-locking structure is engaged, creating a relatively enclosed space inside the outer casing 2 to prevent paint leakage during spraying. At this point, the booster pump 9 is started, transporting the anti-corrosion paint from the anti-corrosion agent storage tank 20 to the spraying pipe 12 through the connecting pipe 8. The paint is then evenly sprayed onto the rotating cable sleeve surface through the spray nozzle at the lower end of the spraying pipe 12. Simultaneously, the drive motor 5 is started, driving the rotating cylinder 22 to rotate through its output end, causing the cable sleeve to rotate synchronously with the rotating cylinder 22, ensuring that all parts of the sleeve surface are evenly covered with anti-corrosion paint. After spraying... After completion, the booster pump 9 is turned off and the heating tube 17 of the drying mechanism is started. Heat is generated through the heating tube 17 inside the protective cover 13 to heat and dry the sprayed cable sleeve, accelerate the curing of the anti-corrosion coating, and improve the adhesion between the coating and the sleeve surface. Then, during drying, the second servo motor 7 is started, which drives the first bolt rod 11 to rotate through the output end. This causes the first scraper 14 to slide along the surface of the protective cover 13 through the threaded connection with the first bolt rod 11 and the guiding action of the guide rod 15, scraping off the coating or impurities attached to the protective cover 13. This ensures that the heat from the heating tube 17 can be transferred smoothly. At the same time, the scraped waste moves with the first scraper 14 to the vicinity of the discharge port and falls into the collection box 4. After scraping is completed, the first servo motor 6 reverses and drives the second bolt rod 16 to rotate, so that the second scraper 21 returns to the initial position. After drying is completed, the heating tube 17 is turned off. After the internal temperature of the device housing 2 drops to a suitable range, the sealing door 3 is opened and the cable sleeve fixed on the fixing rod 10 is removed, completing the anti-corrosion spraying operation.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
