[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0018] Reference Figure 1-Figure 5 As shown, the electrostatic spray fluorescent penetration detection line includes a nozzle 1, one end of the nozzle 1 is connected to a nozzle 2, an expansion cover 3 is installed on the nozzle head 2, and the expansion cover 3 is arranged on the outside of the nozzle head 2 to expand the spraying range of the fluorescent liquid. A discharge port is provided on the expansion cover 3, and a movable groove is provided on the side wall of the discharge port. A blocking plate 4 is slidably installed in the movable groove through an elastic component, and a rotating shaft 5 is horizontally rotated in the expansion cover 3. A mounting rod 6 is fixedly installed at one end of the rotating shaft 5, and scrapers 7 are fixedly installed at both ends of the mounting rod 6. The two scrapers 7 are in sliding contact with the inner wall of the expansion cover 3, and a transmission component for driving the rotating shaft 5 to rotate is provided in the expansion cover 3.

[0019] During the spraying process, the discharge port is blocked by a blocking plate 4 to prevent the fluorescent liquid from overflowing from the discharge port during the spraying process. Two scraping strips 7 are installed at one end of the rotating shaft 5 through the mounting rod 6. When the rotating shaft 5 rotates, the two scraping strips 7 can be driven by the mounting rod 6 to rotate in the expansion cover 3. During the rotation process, the scraping strips 7 contact the inner wall of the expansion cover 3, thereby being able to scrape off the fluorescent liquid remaining on the inner wall of the expansion cover 3, thereby playing a cleaning role.

[0020] The elastic component includes a moving rod 8 fixedly installed on the blocking plate 4 horizontally through the mounting block, a positioning block 9 fixedly installed on the expansion cover 3 and a telescopic spring 10 sleeved on the moving rod 8. The positioning block 9 is provided with a moving hole, one end of the moving rod 8 is slidably inserted in the moving hole, and the two ends of the telescopic spring 10 are fixedly connected with the positioning block 9 and the mounting block respectively. The blocking plate 4 is slidably installed in the moving groove. Under the action of the elastic force of the telescopic spring 10, the blocking plate 4 blocks the discharge port. When the residual fluorescent liquid in the expansion cover 3 needs to be discharged, the blocking plate 4 can be driven to move into the moving groove. During the movement of the blocking plate 4, the moving rod 8 moves on the positioning block 9, and the telescopic spring 10 is compressed. The transmission component includes a winding roller 11 fixedly sleeved on the rotating shaft 5, a torsion spring 12 sleeved on the rotating shaft 5 and a pull rope 13 wound on the winding roller 11. The two ends of the torsion spring 12 are fixedly connected to the side walls of the winding roller 11 and the inner wall of the expansion cover 3 respectively, and one end of the pull rope 13 is fixedly connected to the winding roller 11 The other end is fixedly connected to one end of the blocking plate 4.

One end of the pull rope 13 is fixedly connected to one end of the blocking plate 4 through the guide block 14. When the blocking plate 4 is driven to move into the moving groove, the winding roller 11 is driven to rotate through the guide block 14, and then the rotating shaft 5 is driven to rotate through the winding roller 11. At the same time, the torsion spring 12 is torsionally deformed. At this time, the rotating shaft 5 will The two scrapers 7 are driven to rotate in the expansion cover 3. When the blocking plate 4 is driven to move toward the discharge port, the rotating shaft 5 and the winding roller 11 are driven to rotate in the opposite direction under the action of the torsion force of the torsion spring 12. At the same time, the pull rope 13 is wound around the winding roller 11. Under the action of the guide block 14, the scraper 7 is prevented from touching the pull rope 13 when rotating. The rotation of the rotating shaft 5 can be achieved by moving the blocking plate 4, thereby realizing the cleaning of the inner wall of the expansion cover 3. The operation is simple and convenient, and the cleaning efficiency is effectively improved.

[0021] The discharge port is opened just below the rotating shaft 5, and one end of the blocking plate 4 contacts one end side wall of the expansion cover 3. The setting of the discharge port can facilitate the discharge of the scraped fluorescent liquid from the discharge port.
