[0041] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0042] like Figures 1 to 10 As shown, the anti-corrosion asphalt coating device for submarine cables according to the embodiment of the present invention comprises a frame 1, an operating barrel 2, a cleaning assembly 3, a drying assembly 4, a spraying assembly 5 and an extrusion assembly 6. The operating barrel 2 is rotatably arranged on the frame 1, so the operating barrel 2 comprises a first barrel section 21, a second barrel section 22 and a third barrel section 23. A positioning ring 24 is arranged between the first barrel section 21 and the second barrel section 22 and between the second barrel section 22 and the third barrel section 23. The positioning ring 24 is used for the submarine cable to pass through. The cleaning assembly 3 comprises a spray pipe 31, which is arranged on the first barrel section 21 and is used to rotate with the operating barrel 2 to spray the submarine cable. The water spraying body, the drying component 4 includes an air supply pipe 41, which is arranged at the second barrel section 22 and is used to rotate with the working barrel 2 to dry the submarine cable. The spraying component 5 includes a spraying pipe 51, which is arranged at the third barrel section 23 and is used to rotate with the working barrel 2 to spray asphalt to the submarine cable. The extrusion component 6 includes an extrusion plate 61, which is arranged at the third barrel section 23 and is located on the side of the spraying pipe 51 away from the second barrel section 22. A plurality of extrusion plates 61 are arranged at intervals along the circumference of the working barrel 2 and the radial position along the working barrel 2 is adjustable. The extrusion plate 61 is used to extrude the asphalt on the surface of the submarine cable.

[0043] The working principle of the anti-corrosion asphalt coating device for submarine cables according to the embodiment of the present invention is as follows: the operating cylinder 2 is rotated to pass the submarine cable from the first cylinder section 21 into the operating cylinder 2, and the spray pipe 31 sprays water to the submarine cable. The spray pipe 31 rotates with the operating cylinder 2 to realize circumferential spraying of the submarine cable, so as to ensure that the dust and debris attached to the outer surface of the submarine cable are comprehensively cleaned during the rotation process, and the cable surface is ensured to be clean and free of impurities, thereby improving the tightness and uniformity of the subsequent asphalt coating, and enhancing the protective effect of the anti-corrosion layer. After completing the flushing operation of the submarine cable, the submarine cable is continuously moved to the second cylinder section 22, and the air supply pipe 41 transports gas to the submarine cable to speed up the drying of the water attached to the peripheral side of the submarine cable, ensuring that the cable surface is dry and free of residue, thereby improving the tightness and uniformity of the asphalt coating layer, and enhancing the protective effect of the anti-corrosion layer. The cable surface after drying is drier, which is conducive to the rapid solidification of the asphalt coating layer. , continue to move the submarine cable to the third barrel section 23, the two positioning rings 24 support the submarine cable, the spray pipe 51 rotates with the working barrel 2, and sprays the surrounding side of the submarine cable in turn to ensure the uniformity of the spraying on the surface of the submarine cable. At the same time, the position of the extrusion plate 61 can be adjusted to extrude the asphalt coated on the outer surface of cables of different diameters, so that the extrusion plate 61 can be pressed tightly on the surrounding side of the submarine cable to achieve the extrusion of the asphalt on the surrounding side of the submarine cable, so that during the rotation and extrusion process, the asphalt coating can penetrate into the tiny pores on the surface of the cable to form a tight adhesion layer. This tight adhesion relationship helps to improve the wear resistance and corrosion resistance of the coating, thereby extending the service life of the submarine cable. The coating formed by the asphalt coating on the surface of the submarine cable has a certain hardness, which helps to resist mechanical impact and friction in the submarine environment, protect the submarine cable from damage, and improve the service life of the submarine cable.

[0044] The submarine cable anti-corrosion asphalt coating device of the embodiment of the present invention can pre-treat the submarine cable to facilitate the adhesion of the asphalt on the submarine cable, and increase the adhesion and coating uniformity of the asphalt on the surface of the submarine cable through the extrusion plate 61, thereby ensuring the anti-corrosion protection of the submarine cable and increasing the service life of the submarine cable.

By setting the extrusion wheel 62, when the extrusion plate 61 squeezes the asphalt on the submarine cable, the extrusion wheel 62 can rotate relative to the extrusion plate 61 under the action of the working cylinder 2 and the asphalt, thereby improving the uniformity of the asphalt coating on the submarine cable.

[0048] In some embodiments, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the cleaning assembly 3 includes a first annular cylinder 32, a first annular plate 33 and a liquid inlet pipe 34.
