DETAILED DESCRIPTION

[0038] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are part of the embodiments of the present invention, rather than all of the embodiments. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work should fall within the scope of protection of the present invention.

[0039] Furthermore, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily obscuring the concepts disclosed in the present invention.

[0040] Exemplary embodiments are described in detail herein, with examples illustrated in the accompanying drawings. When the following description refers to the drawings, identical numerals in different figures represent identical or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present invention.

[0041] Reference Manual Figures 1 to 20 , showing a structural schematic diagram of a cable surface protective oil application device provided by an embodiment of the present invention.

[0042] The structure of a cable surface protective oil coating device provided by an embodiment of the present invention includes: a tank body 101, in which 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 provided. Before using this embodiment, refer to Figure 2 After being pulled off the production line, the cable needs to be passed through the first winding pulley 105, two symmetrically arranged second winding pulleys 106, the third winding pulley 107, two symmetrically arranged fourth winding pulleys 108, and the fifth winding pulley 109 in sequence. Several oil scraping modules 300 are installed in a horizontal array in the tank 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.

[0043] Reference Figure 6 and Figure 7 The oil scraping module 300 includes two symmetrically arranged second fixed brackets 301, two first connecting plates 302, a plurality of scrapers 303, a slide groove 304 opened on the second fixed bracket 301, two sliding rods 305, two electric telescopic rods 306, a fixed ring 307 and a shrinking ring 308.

[0044] The two second fixing brackets 301 are fixed to the inner side of the tank body 101 respectively. The two second fixing brackets 301 are fixedly connected to the fixing ring 307 through the first connecting plate 302. A plurality of scrapers 303 are provided on one side of the fixing ring 307 (refer to Figure 6 and Figure 7 In this embodiment, the number of scrapers 303 is three), the sliding rod 305 is slidably installed in the corresponding sliding groove 304, the shrinking ring 308 is fixedly installed between the two sliding rods 305, and the two electric telescopic rods 306 are located between the first connecting plate 302 and the sliding rod 305. The two ends of the electric telescopic rod 306 are respectively fixedly connected to the first connecting plate 302 and the sliding rod 305, and the shrinking ring 308 is slidably matched with the scraper 303.

[0045] In this embodiment, the scrapers 303 are made of elastic sheet metal. The three scrapers 303 are radially symmetrically arranged at 120°, forming a claw-like closed configuration. The cable passes through the spaces between the three scrapers 303. A gap exists between adjacent scrapers 303 to allow scraped protective oil to pass through. When the electric telescopic rod 306 retracts, the contraction ring 308 displaces axially toward the fixed ring 307, generating a radial extrusion force that elastically deforms the scrapers 303. The amount of contraction in the inner diameter of the scraping end of the scraper 303 is linearly proportional to the stroke length of the electric telescopic rod 306. As the cable passes through, the shear force between the scrapers 303 and the cable surface increases, enhancing the protective oil stripping effect and reducing the oil film thickness. This results in a thinner protective oil film on the cable surface after it passes through the scraper 303 oil scraping module 300. On the contrary, when the electric telescopic rod 306 is extended, the shrinking ring 308 produces a reverse displacement, and the elastic restoring force of the scraper 303 causes the inner diameter of the scraping end to expand, thereby increasing the working gap. In this state, the protective oil passing rate is significantly improved, so that the thickness of the protective oil on the surface of the cable after passing through the scraper 303 scraping module 300 is thicker. This mechanism realizes the control of the oil film thickness.

[0046] In this embodiment, there are two oil scraping modules 300, and the scrapers 303 of the two oil scraping modules 300 are installed at a 60° angle offset to form a complementary notch distribution. This arrangement allows the protective oil on the surface of the cable to be more evenly distributed after passing through the two oil scraping modules 300.

[0047] In a possible embodiment, the number of oil scraping modules 300 may be greater. Providing multiple oil scraping modules 300 can ensure that the protective oil on the surface of the cable is more evenly distributed after the cable passes through two oil scraping modules 300.

[0048] In a possible implementation manner, based on the above embodiment, referring to Figure 2 、 Figure 4 and Figure 5A vibration oil removal module 200 is also installed in the tank body 101. The vibration oil removal module 200 includes a first fixed bracket 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 conduction rod 208.

[0049] The outer sleeve 204 is fixedly mounted on the inner side of the tank body 101 through the first fixing bracket 201, the inner sleeve 202 is sleeved inside the outer sleeve 204 and is slidably matched therewith, the baffle 203 is fixedly mounted on one end of the inner sleeve 202, a 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 mounted on the mounting bracket 206, and a plurality of vibration conduction rods 208 are provided on the inner side of the inner sleeve 202. Figure 2 The vibration oil removal module 200 is located between the second winding pulley 106 and the third winding pulley 107 . The worker holds the cable and passes it around the second winding pulley 106 , then through the inner sleeve 202 and then around the third winding pulley 107 .

[0050] In this embodiment, the small vibration motor 207 vibrates, causing the inner sleeve 202 to oscillate up and down within a certain range. This vibration is transmitted to the cable inside the sleeve via the vibration transmission rod 208. High-frequency mechanical vibration strips away excess protective oil from the cable surface, effectively controlling the amount of oil film adhered. The vibration transmission rod 208 is made of flexible rubber and has an overall nail-like structure. Its base end is embedded and fixed within the inner sleeve 202, while the other end is designed with a tapered contact surface, ensuring sufficient and uniform vibration transmission to the cable surface and reducing contact between the vibration transmission rod 208 and the protective oil on the cable surface. This structure ensures efficient transmission of vibration energy while avoiding mechanical damage to the cable insulation layer.

[0051] In a possible implementation manner, based on the above embodiment, referring to Figure 2 and Figure 8 A heating module 400 is installed in the tank body 101 . The heating module 400 includes a third fixing bracket 401 , two first positioning tubes 402 , a heating tube 403 and a heating wire 404 .

[0052] The two first positioning tubes 402 are fixedly installed on the inner side of the trough body 101 through the third fixing bracket 401, and the heating tube 403 is clamped and installed between the two first positioning tubes 402. A heating wire 404 is wrapped around the heating tube 403. The cable passes through the first positioning tube 402 and the heating tube 403. The cable has no direct contact with the first positioning tube 402 and the heating tube 403. After the staff holds the cable and passes it around the fifth winding pulley 109, the cable should be passed through the first positioning tube 402 and the heating tube 403.

[0053] In this process embodiment, after the cable passes through the oil scraping module 300, it passes through the heating module 400 for heat treatment. Precise temperature control devices gently heat the cable, causing the residual protective oil on the surface to slightly melt. This process achieves three key effects: First, the molten protective oil automatically spreads under surface tension, forming a uniform oil film. Second, the slightly melted state facilitates the penetration of the protective oil into the microporous structure of the cable surface, improving adhesion. Third, the heat-treated protective oil restores its optimal viscosity, fully demonstrating its protective properties against oxidation and moisture erosion.

[0054] In a possible implementation manner, based on the above embodiment, referring to Figure 2 and Figure 9 A cooling module 500 is installed in the tank body 101 , and the cooling module 500 includes a fourth fixing bracket 501 , a second positioning tube 502 , a cooling fin 503 , a cooling radiator 504 , a fan 505 and a heat pipe 506 .

[0055] The second positioning tube 502 is fixedly installed on the inner side of the tank body 101 through the fourth fixing bracket 501, the cooling fin 503 is embedded in the second positioning tube 502, the radiator 504 is installed on one side of the cooling fin 503, and the fan 505 is installed on the radiator 504. Several heat pipes 506 are embedded in the second positioning tube 502, and the cable passes through the second positioning tube 502. The cable has no direct contact with the second positioning tube 502. After the staff holds the cable around the heating module 400, the cable should continue to pass through the second positioning tube 502, and finally the cable should be wound on the winding drum driven by the corresponding servo motor. The winding drum is a commonly used existing technology in this field and is not drawn in the figure, so it will not be elaborated on here.

[0056] In this embodiment, the cable heated by the heating module 400 can be cooled to promote a smooth transition of the protective oil from liquid to semi-solid. The cooling end temperature should be maintained at 5-8°C above the solidification point of the protective oil to ensure the formation of a uniform microcrystalline structure and significantly improve the cable's anti-penetration performance through oil film shaping.

[0057] In a possible implementation manner, based on the above embodiment, it should be noted that the winding pulley of the present application is divided into two types, one of which is Figure 2 The first winding pulley 105 is just a simple winding wheel, another reference Figure 10 and Figure 11 The winding pulley includes a mounting seat 601, a rotating shaft 602, a mounting tube 603, a discharge trough 604, a plurality of support hairs 605 and a buffer tube 606.

[0058] The mounting seat 601 can be installed on the inner side of the trough body 101, the rotating shaft 602 is installed on the mounting seat 601, the buffer tube 606 is fixedly installed on the rotating shaft 602, the mounting tube 603 is sleeved and fixedly installed on the buffer tube 606, and a discharge groove 604 is opened on the mounting tube 603, and a number of support hairs 605 are evenly distributed in the discharge groove 604.

[0059] In this embodiment, when a cable covered in protective oil passes over a pulley, the array of support bristles 605 forms microscopic support points, transforming traditional surface contact into multi-point contact, effectively reducing the risk of oil film transfer. The temporary grooves created by the support bristles 605 as they scratch the oil film are automatically repaired by the surface tension of the protective oil.

[0060] In a possible embodiment, based on the above embodiment, a partition 110 is installed in the tank body 101, and the tank body 101 is divided into a recovery tank 111 and a protective oil tank 112 by the partition 110. The oil scraping module 300 is located in the recovery tank 111, and a motor 113 is fixedly installed in the protective oil tank 112. Two groups of brushes 114 are installed on the motor 113, and the two groups of brushes 114 are arranged opposite to each other. When this embodiment is used, protective oil is filled in the protective oil tank 112, and the recovery tank 111 is used to recover the protective oil. The two groups of brushes 114 are located between the two second winding pulleys 106, and the motor 113 is installed at the bottom inner side of the protective oil tank 112.

[0061] A first window 102 and a second window 103 are provided on the tank body 101. The first window 102 and the second window 103 are respectively arranged corresponding to the protective oil tank 112 and the recovery tank 111. A liquid replenishing tube 104 is installed on the tank body 101. Glass windows are installed in the first window 102 and the second window 103 for convenient observation of the tank body 101.

[0062] In this embodiment, when the cable is initially immersed in the protective oil in protective oil tank 112, gas exchange occurs when the cable surface contacts the oil, causing bubbles to form on the cable's outer sheath. At this point, a set of rotating brushes 114, driven by motor 113, begins to operate synchronously. The symmetrically arranged brushes 114 physically clean the cable surface passing between them, effectively stripping and removing the bubbles and ensuring complete coverage of the protective oil on the cable surface.

[0063] In a possible implementation, based on the above embodiment, a second liquid level sensor 119 is installed in the recovery tank 111 , a first liquid level sensor 115 is installed in the protective oil tank 112 , and a recovery plate 116 is fixedly installed on the partition 110 .

[0064] The recovery tank 111 is connected to the protection oil tank 112 through an oil return pipe 117, and a pump body 118 (such as Figure 1 shown).

[0065] In this 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 receives a signal and replenishes the protective oil into the protective oil tank 112 through the liquid replenishing pipe 104 (the liquid replenishing pipe 104 is connected to the protective oil replenishing pump, which is not shown in the figure). When the protective oil level in the recovery tank 111 contacts the second liquid level sensor 119, the second liquid level sensor 119 receives a signal and transports the protective oil in the recovery tank 111 into the protective oil tank 112 through the pump body 118.

[0066] Optionally, this embodiment also includes a preparation standard for a protective oil, which is composed of 60 parts of hydrogenated polyisobutylene, 23 parts of microcrystalline wax, 5.5 parts of nano-silicon dioxide, 10 parts of C5 petroleum resin, 1 part of phosphate ester, and 0.5 parts of antioxidant.

[0067] Hydrogenated polyisobutylene is used to provide a temperature-sensitive skeleton, microcrystalline wax is used to regulate the phase change point crystal structure, nanosilica is used to prevent sagging in the solid state, C5 petroleum resin is used to improve low-temperature adhesion, phosphate ester is used for corrosion protection, and antioxidants are used to prevent oxidation of protective oil.

[0068] The above protective oil has a viscosity of 800-1200cp (pumpable state) when the temperature is above 50 degrees, and is a semi-solid with a needle penetration of 40-60 (0.1mm) when the temperature is below 50 degrees.

[0069] It should be noted that before using this embodiment, after the cable is completed from the production line, first refer to Figure 2 and Figure 12 , pass the cable around the corresponding winding pulley and module, pull it out from one end of the cooling module 500 and install it on the corresponding winding drum.

[0070] The steps for using this embodiment are as follows: Step 1: The cable moves from right to left on the winding drum (refer to Figure 12 The cable will first be immersed in the protective oil (the temperature of the protective oil in the protective oil tank 112 should be above 50 degrees, and the protective oil should be in a viscous paste), and some bubbles will be attached to the cable (refer to the cross-sectional view of the cable at this time). Figure 13 , the position of the cable screenshot is referenced Figure 12 a1), at this time, the brush 114 is driven by the motor 113 to rotate to remove the bubbles on the cable.

[0071] In the 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. When the vibration occurs, the inner casing 202 will shake up and down within a certain range. The vibration is transmitted to the cable inside the casing through the vibration transmission rod 208, and the excess protective oil layer on the cable surface is stripped by high-frequency mechanical vibration, effectively controlling the amount of oil film adhesion (refer to Figure 14 and Figure 15 , Figure 14 This is a cross-sectional view of the cable before passing through the vibration oil removal module 200. Figure 12 a2 in . Figure 15 This is a cross-sectional view of the cable after passing through the vibration oil removal module 200. Figure 12 In this step, the protective oil is in the form of a thick paste.

[0072] In the third step, the cable then passes through the fourth winding pulley 108 and through several oil scraping modules 300, and then is wound on the fifth winding pulley 109. When the cable passes through the oil scraping module 300, the protective oil on the cable surface is scraped off to a certain extent by multiple sets of scrapers 303 with adjustable opening sizes to prevent a large amount of protective oil from sticking to the cable (refer to Figure 16 and Figure 17 At this time, when the protective oil on the cable surface is first scraped off by the scraper 303 in the first scraping module 300, the position is referenced Figure 12 a4 in. The cross-sectional view of the cable, refer to Figure 18 and 19 At this time, the protective oil on the cable surface is scraped off for the second time by the scraper 303 in the second scraping module 300. Figure 12 a5 in the diagram. The cross-sectional view of the cable. Figures 16 to 19 , it can be easily seen that after the multiple scrapers 303 scrape the cable, the protective oil on the cable surface is more uniform). In this step, the protective oil is in a viscous paste.

[0073] Step 4: After the cable passes through the fifth winding pulley 109, it passes through the heating module 400 and the cooling module 500 in sequence. When passing through the heating module 400, the heating module 400 heats the cable, causing the protective oil on its surface to become viscous and to increase its temperature (to prevent the protective oil from cooling and solidifying), so that the protective oil is evenly distributed on the cable surface due to surface tension (refer to the cross-sectional view of the cable at this time). Figure 20 , the position of the cross-section diagram refers to Figure 12(a6 in the figure) The heated cable is then cooled by the cooling module 500 to cool the protective oil on the cable surface (this allows the protective oil to have higher adhesion, forming a uniform and dense protective film that effectively prevents the intrusion of moisture, oxygen, and other corrosive substances, protecting the cable from corrosion and damage). Finally, the cable passes through the cooling module 500 and is wound on the corresponding winding drum.

[0074] It should be further explained that all of the above embodiments include an electrical control cabinet (not shown in the figures).
