Its main functions include moisture protection, sealing, and corrosion prevention. It can significantly extend the cable's storage life and effectively extend its service life, reducing maintenance and replacement costs.

[0003] Existing cable surface protective oil coating equipment generally adopts the process of passing the cable through the winding pulley in the protective oil bath, and using the oil bath to immerse the cable surface to form an oil layer; however, this process has significant defects: the thickness of the formed oil film is uneven and the coverage is insufficient, which means that the protective oil cannot fully play its protective role on the cable surface.

In the process of immersing the cable in the protection oil, the rotating brush is used to effectively remove the small bubbles attached to the surface of the cable, ensuring that the protection oil can completely and uniformly cover the surface of the cable; the surface often adheres to a lot of protection oil, which can be stripped from the surface of the cable by using the high-frequency mechanical vibration generated by the small vibration motor, effectively controlling the oil film adhesion amount, ensuring the formation of a continuous and uniform oil film, and avoiding oil waste; this combined process solves the problems of uneven coating and excessive oil adhesion in the traditional oil immersion method, significantly improves the integrity and consistency of the protection oil coating, and lays a good foundation for the subsequent solidification process.

It should be understood that these descriptions are only exemplary, and are not used to limit the scope of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor should be within the scope of protection of the present application.

[0047] In addition, in the following description, the description of the known structures and technologies is omitted to avoid unnecessary confusion of the concepts disclosed in the present application.

[0048] The exemplary embodiments will be described in detail below with reference to the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application.

[0049] Referring to the drawings Figures 1 to 20 , a structural schematic diagram of a cable surface protection oil coating device provided by an embodiment of the present application is shown.

[0050] The structure of the cable surface protection oil coating device provided by the embodiment of the present application comprises a groove body 101, a first winding pulley 105, two symmetrically arranged second winding pulleys 106, a third winding pulley 107, two symmetrically arranged fourth winding pulleys 108, a fifth winding pulley 109 and a plurality of oil scraping modules 300 are arranged in the groove body 101. Before use, refer to Figure 2 , the cable is sequentially wound around the first winding pulley 105, the two symmetrically arranged second winding pulleys 106, the third winding pulley 107, the two symmetrically arranged fourth winding pulleys 108 and the fifth winding pulley 109. The plurality of oil scraping modules 300 are horizontally arrayed in the groove body 101, the oil scraping module 300 is located between the two fourth winding pulleys 108, and the cable passes through the oil scraping module 300.

[0051] Refer to Figure 6 and Figure 7 , the oil scraping module 300 comprises two symmetrically arranged second fixed supports 301, two first connecting plates 302, a plurality of scraping plates 303, a sliding groove 304 opened on the second fixed support 301, two sliding rods 305, two electric telescopic rods 306, and a fixed ring 307 and a contraction ring 308.

[0052] Two second fixing supports 301 are fixed inside the groove body 101, and the two second fixing supports 301 are fixedly connected with the fixed ring 307 through the first connecting plate 302. A plurality of scrapers 303 are arranged on one side of the fixed ring 307 (refer to Figure 6 With Figure 7 In the embodiment, the number of the scrapers 303 is three), the slide rod 305 is slidingly installed in the corresponding slide groove 304, the contraction ring 308 is fixedly installed between the two slide rods 305, the two electric telescopic rods 306 are located between the first connecting plate 302 and the slide rod 305, and the two ends of the electric telescopic rod 306 are fixedly connected to the first connecting plate 302 and the slide rod 305 respectively. The contraction ring 308 is slidingly connected with the scraper 303.

[0053] In the embodiment, the scraper 303 is made of elastic metal sheet material, and the three scrapers 303 are radially symmetrically distributed at an angle of 120° to form a clamping jaw-like folding shape. The cable passes through the space formed between the three scrapers 303, and there is a gap between the adjacent scrapers 303, which is used for scraping the protective oil. When the electric telescopic rod 306 performs the contraction action, the contraction ring 308 is displaced along the axial direction to the fixed ring 307, a radial extrusion force is generated to make the scraper 303 elastically deform, the contraction amount of the inner diameter of the scraping end of the scraper 303 is in a linear relationship with the stroke length of the electric telescopic rod 306. At this time, when the cable passes, the shear force formed between the scraper 303 and the surface of the cable increases, the stripping effect of the protective oil is improved, the oil film thickness is thinned, and the thickness of the protective oil on the surface of the cable after passing through the scraper 303 and the oil scraping module 300 is relatively thin. Conversely, when the electric telescopic rod 306 is stretched, the contraction ring 308 is reversely displaced, the elastic recovery force of the scraper 303 makes the inner diameter of the scraping end of the scraper 303 expand, and then the working gap is increased. In this state, the passing rate of the protective oil is significantly improved, the thickness of the protective oil on the surface of the cable after passing through the scraper 303 and the oil scraping module 300 is relatively thick, and this mechanism realizes the control of the oil film thickness.

[0054] In the embodiment, the number of the oil scraping modules 300 is two, and the scrapers 303 of the two oil scraping modules 300 are installed at an angle of 60° and are staggered to form a complementary gap distribution. In this way, the protective oil adhered to the cable can be more uniformly distributed on the surface of the cable after passing through the two oil scraping modules 300.

[0055] In a possible implementation, the number of the oil scraping modules 300 can be more, and a plurality of oil scraping modules 300 are arranged, so that the protective oil adhered to the cable can be more uniformly distributed on the surface of the cable after passing through the two oil scraping modules 300.

[0056] In a possible implementation, on the basis of the above embodiment, with reference to Figure 2 , Figure 4 With Figure 5, the groove body 101 is also fitted with a vibration residual oil removal module 200, the vibration residual oil removal module 200 comprising a first fixed support 201, an inner sleeve 202, a baffle 203, an outer sleeve 204, a spring 205, a mounting bracket 206, a small vibration motor 207 and a vibration transmission rod 208.

[0057] The outer sleeve 204 is fixedly installed inside the groove body 101 through the first fixed support 201, the inner sleeve 202 is sleeved inside the outer sleeve 204 and is in sliding fit with the outer sleeve 204, the baffle 203 is fixedly installed at one end of the inner sleeve 202, the spring 205 is installed between the baffle 203 and the outer sleeve 204, the spring 205 is sleeved on the inner sleeve 202, the mounting bracket 206 is located below the outer sleeve 204, the small vibration motor 207 is installed on the mounting bracket 206, and the inner side of the inner sleeve 202 is provided with a plurality of vibration transmission rods 208. Figure 2 The vibration residual oil removal module 200 is located between the second wire winding pulley 106 and the third wire winding pulley 107, and after the staff holds the cable and winds it around the second wire winding pulley 106, the cable passes through the inner sleeve 202 and then winds around the third wire winding pulley 107.

[0058] In the embodiment, the small vibration motor 207 vibrates, when the vibration occurs, the inner sleeve 202 will shake up and down within a certain range, the vibration is transmitted to the cable inside the sleeve through the vibration transmission rod 208, the excess protective oil layer on the surface of the cable is stripped by using high-frequency mechanical vibration, the oil film adhesion amount is effectively controlled, the vibration transmission rod 208 is made of flexible rubber material and has a whole nail-shaped structure, the base end of the vibration transmission rod 208 is embedded and fixed in the inner sleeve 202, the other end is designed as a tapered contact surface, so that the vibration transmission rod 208 can realize sufficient and uniform vibration transmission with the surface of the cable and can reduce the contact between the vibration transmission rod 208 and the protective oil on the surface of the cable, which not only ensures efficient transmission of vibration energy but also avoids mechanical damage to the cable insulation layer.

[0059] In a possible implementation, on the basis of the above embodiment, referring to Figure 2 and Figure 8 The heating module 400 is installed in the groove body 101, the heating module 400 comprising a third fixed support 401, two first positioning pipes 402, a temperature rising pipe 403 and a heating wire 404.

[0060] The two first positioning pipes 402 are fixedly installed inside the groove body 101 through the third fixed support 401, the temperature rising pipe 403 is clamped and installed between the two first positioning pipes 402, the heating wire 404 is wound on the temperature rising pipe 403, the cable passes through the first positioning pipe 402 and the temperature rising pipe 403, and the cable does not have direct contact with the first positioning pipe 402 and the temperature rising pipe 403, and after the staff holds the cable and winds it around the fifth wire winding pulley 109, the cable should pass through the first positioning pipe 402 and the temperature rising pipe 403.

[0061] In the present process embodiment, after the cable is treated by the oil scraping module 300, it will pass through the heating module 400 for heat treatment, and the cable is heated by the precise temperature control device to a slightly melted state of the residual protective oil on the surface. This process can achieve three key effects: first, the molten protective oil automatically spreads under the action of surface tension to form an oil film layer with uniform thickness. Second, the slightly melted state helps the protective oil penetrate into the micro-porous structure of the cable surface, improving adhesion. Third, the heat-treated protective oil can restore its optimal viscosity characteristics, fully exerting the protection functions of anti-oxidation, moisture erosion, etc.

[0062] In one possible implementation, on the basis of the above embodiment, referring to Figure 2 and Figure 9 A cooling module 500 is installed in the tank body 101, which includes a fourth fixed support 501, a second positioning pipe 502, a refrigeration fin 503, a cooling row 504, a fan 505, and a heat pipe 506.

[0063] The second positioning pipe 502 is fixedly installed on the inner side of the tank body 101 through the fourth fixed support 501, the refrigeration fin 503 is embeddedly installed in the second positioning pipe 502, the cooling row 504 is cooperatively installed on one side of the refrigeration fin 503, the fan 505 is cooperatively installed on the cooling row 504, and a plurality of heat pipes 506 are embeddedly installed in the second positioning pipe 502. The cable passes through the second positioning pipe 502, and the cable does not have direct contact with the second positioning pipe 502. After the staff member holds the cable to pass around the heating module 400, the cable should continue to pass through the second positioning pipe 502, and finally the cable is wound on the winding reel driven by the corresponding servo motor. The winding reel is a prior art commonly used in the art, which is not shown in the figure and will not be described in more detail here.

[0064] In the present embodiment, the cable heated by the heating module 400 can be cooled to smoothly transition the protective oil from a liquid state to a semi-solid state. The cooling endpoint temperature should be maintained at 5-8°C above the freezing point of the protective oil to ensure the formation of uniform microcrystalline structure, thereby significantly improving the anti-permeability of the cable.

[0065] In one possible implementation, on the basis of the above embodiment, it should be noted that the winding pulley of the present application is divided into two types. One is the first winding pulley 105 in Figure 2 which is simply a winding wheel, and the other is the winding pulley in Figure 10 and Figure 11 The winding pulley includes a mounting seat 601, a rotating shaft 602, a mounting pipe 603, a feeding groove 604, a plurality of support hairs 605, and a buffer pipe 606.

[0066] The mounting seat 601 is mounted in the groove body 101, the rotating shaft 602 is mounted on the mounting seat 601, the buffer pipe 606 is fixedly mounted on the rotating shaft 602, the mounting pipe 603 is sleeved and fixedly mounted on the buffer pipe 606, the discharging groove 604 is formed in the mounting pipe 603, and the supporting hairs 605 are uniformly distributed in the discharging groove 604.

[0067] In the embodiment, when the cable adhering to the protective oil passes through the pulley, the array of the supporting hairs 605 forms micro support points, converts the traditional surface contact into a multi-point contact mode, and effectively reduces the risk of oil film transfer. The temporary groove formed by the supporting hairs 605 passing through the oil film can be automatically repaired under the surface tension of the protective oil.

[0068] In a possible implementation, on the basis of the above embodiment, the groove body 101 is mounted with a partition plate 110, the groove body 101 is divided into a recovery groove 111 and a protective oil groove 112 by the partition plate 110, the oil scraping module 300 is located in the recovery groove 111, the motor 113 is fixedly mounted in the protective oil groove 112, two groups of brushes 114 are mounted on the motor 113, the two groups of brushes 114 are oppositely arranged, in the use of the embodiment, the protective oil is filled in the protective oil groove 112, the recovery groove 111 is used for recovery of the protective oil, the two groups of brushes 114 are located between the two second wire winding pulleys 106, and the motor 113 is mounted on the bottom of the inner side of the protective oil groove 112.

[0069] The first window 102 and the second window 103 are formed in the groove body 101 and correspondingly arranged with the protective oil groove 112 and the recovery groove 111, the liquid supplementing pipe 104 is mounted on the groove body 101, and glass windows are mounted in the first window 102 and the second window 103, so that the groove body 101 can be observed.

[0070] In the embodiment, in the process that the cable is initially immersed in the protective oil in the protective oil groove 112, because of the gas replacement phenomenon when the cable surface contacts the oil, the adhering bubbles are formed on the surface of the cable outer sheath. At this time, the rotating brush 114 group driven by the motor 113 starts to operate synchronously, the cable surface passing through the two groups of symmetrically arranged brushes 114 is physically cleaned through the cooperation of the two groups of brushes 114, the adhering bubbles are effectively stripped and removed, and the complete coverage of the protective oil on the cable surface is ensured.

[0071] In a possible implementation, on the basis of the above embodiment, the second liquid level sensor 119 is mounted in the recovery groove 111, the first liquid level sensor 115 is mounted in the protective oil groove 112, and the recovery plate 116 is fixedly mounted on the partition plate 110.

[0072] The recovery tank 111 is communicated with the protective oil tank 112 through an oil return pipe 117, and a pump body 118 is installed on the oil return pipe 117 (as shown in Figure 1 ).

[0073] In the embodiment, when the protective oil level in the protective oil tank 112 is below the first liquid level sensor 115, the first liquid level sensor 115 obtains a signal, and the protective oil is supplemented into the protective oil tank 112 through the liquid supplement pipe 104 (the liquid supplement pipe 104 is connected with a protective oil supplement pump, which is not shown in the figure), and when the protective oil level in the recovery tank 111 contacts the second liquid level sensor 119, the second liquid level sensor 119 obtains a signal, and the protective oil in the recovery tank 111 is transported into the protective oil tank 112 through the pump body 118.

[0074] Optionally, the embodiment further includes a preparation standard of the protective oil, and the protective oil is composed of 60 parts of hydrogenated polyisobutene, 23 parts of microcrystalline wax, 5.5 parts of nano silicon dioxide, 10 parts of carbon five petroleum resin, 1 part of phosphate ester, and 0.5 part of antioxidant.

[0075] The hydrogenated polyisobutene is used to provide a temperature-sensitive skeleton, the microcrystalline wax is used to regulate the phase change point crystalline structure, the nano silicon dioxide is used to prevent sagging in solid state, the carbon five petroleum resin is used to improve the low-temperature adhesion, the phosphate ester is used to prevent corrosion, and the antioxidant is used to prevent oxidation of the protective oil.

[0076] The above protective oil has a viscosity of 800-1200 cp (pumpable state) at 50 degrees or above, and is a semi-solid with a penetration of 40-60 (0.1 mm) at 50 degrees or below.

[0077] It should be noted that, before use, the cable is completed from the production line, and first, the cable is pulled out from the corresponding winding disc at one end of the cooling module 500 with reference to Figure 2 and Figure 12 , the cable is wound around the corresponding winding pulley and module.

[0078] The use steps of the embodiment are as follows:

[0079] Firstly, under the winding of the winding disc, the cable moves from right to left (with reference to the direction of Figure 12 ), the cable is first immersed in the protective oil (the temperature of the protective oil in the protective oil tank 112 should be 50 degrees or above, so as to ensure that the protective oil is in a thick paste state), and there will be a certain amount of bubbles attached to the cable (at this time, the cross-sectional view of the cable is shown in Figure 13 , and the position of the cross-sectional view of the cable is shown in a1 of Figure 12 ), at this time, the brush 114 is driven to rotate by the motor 113, so as to remove the bubbles on the cable.

[0080] Second step, after the cable passes through the second winding pulley 106, it passes through the vibration oil removal module 200 and passes through the third winding pulley 107. When the cable passes through the vibration oil removal module 200, the small vibration motor 207 vibrates, and when the vibration occurs, the inner sleeve 202 will vibrate up and down within a certain range. The vibration is transmitted to the cable inside the sleeve through the vibration transmission rod 208. The excess protective oil layer on the surface of the cable is stripped by high-frequency mechanical vibration, effectively controlling the amount of oil film attached (refer to Figure 14 With Figure 15 , Figure 14 is the cable cross-sectional view before passing through the vibration oil removal module 200. The position is referred to as a2 in Figure 12 . Figure 15 is the cable cross-sectional view after passing through the vibration oil removal module 200. The position is referred to as a3 in Figure 12 . The protective oil at this step is in a thick paste state.

[0081] Third step, the cable then passes through the fourth winding pulley 108 and passes through several oil scraping modules 300, and then winds around the fifth winding pulley 109. When the cable passes through the oil scraping module 300, the protective oil on the surface of the cable is scraped by multiple groups of adjustable opening size scraping plates 303, preventing a large amount of protective oil from sticking to the cable (refer to Figure 16 With Figure 17 At this time, the protective oil on the surface of the cable is scraped for the first time by the scraping plate 303 in the first oil scraping module 300. The position is referred to as a4 in Figure 12 . Figure 18 With 19 At this time, the protective oil on the surface of the cable is scraped for the second time by the scraping plate 303 in the second oil scraping module 300. The position is referred to as a5 in Figure 12 . Figures 16 to 19 The cross-sectional view of the cable can be easily known after the cable is scraped by multiple scraping plates 303, and the protective oil on the surface of the cable is more uniform). The protective oil at this step is in a thick paste state.

[0082] Fourth step, after the cable passes through the fifth winding pulley 109, it passes through the heating module 400 and the cooling module 500 in turn. When passing through the heating module 400, the heating module 400 will heat the cable, causing the thick protective oil on its surface to warm up (to prevent the protective oil from cooling and solidifying), and causing the protective oil to be evenly distributed on the surface of the cable due to surface tension (at this time, the cross-sectional view of the cable is referred to Figure 20 , and the position of the cross-sectional view is referred to Figure 12After the heating, the cable is cooled by the cooling module 500, so that the protective oil on the surface of the cable is cooled (so that the adhesion of the protective oil is higher, a uniform and dense protective film is formed, which effectively prevents the invasion of moisture, oxygen and other corrosive substances, and protects the cable from corrosion and damage), and finally the cable is wound on the corresponding reel after passing through the cooling module 500.
