Description

Technical Field

[0001] This invention relates to the field of power technology, specifically to an oil skimming mechanism of an oil-passing device for power generation. Background Technology

[0002] Oil is applied to electrical wires for insulation and protection. During the wire manufacturing process, the conductors need to be isolated from the outside environment to prevent current leakage or short circuits. Oil has excellent insulating properties and can effectively isolate the conductors inside the wire, ensuring that the current flows along the predetermined path.

[0003] CN221008677U discloses an oil scraping mechanism for an oiling device used in cable production. The mechanism includes an oil tank, a vertical plate fixedly installed inside the tank, and a through-hole on one side of the vertical plate. A vertical rod is located on one side of the vertical plate inside the oil tank, and a fixed plate is fixedly connected to the vertical rod. An oil flow channel is formed on the fixed plate. Support plates are fixedly connected to both ends of the top of the fixed plate on either side of the oil flow channel. An oil scraping sleeve is fixedly installed on a pair of support plates. A cable passes through the oil scraping sleeve via an oil scraping plate. This patent utilizes the cooperation of the vertical rod, fixed plate, and support plates to allow the cable to pass through the oil scraping sleeve. Simultaneously, the oil scraping plate scrapes excess oil from the cable surface onto the oil flow channel, from which it flows back to the oiling mechanism. This achieves the recycling and reuse of the scraped oil, facilitating complete oil scraping of the cable's outer surface and improving cable utilization efficiency. Although the device solves the above problems, it is prone to problems such as poor oil flow due to low temperature, resulting in poor oiling effect on wires. Therefore, an oil scraping mechanism for an oiling device for power production is proposed to solve the above problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an oil skimming mechanism for an oil-passing device for power generation, which addresses the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: an oil scraping mechanism for an oil-passing device used in power production, comprising a cable and a housing. The housing has a cable inlet at the rear. Multiple fixed rollers are rotatably connected to the inner wall of the housing. An oil tank is located inside the housing. A clamping and heat-insulating mechanism is provided on the bottom inner wall of the oil tank. A reciprocating screw is rotatably connected to the front of the housing. An oil scraping device is provided on the circumferential surface of the reciprocating screw. A vibration mechanism is rotatably connected to the inner wall of the housing. An oil guide plate is located inside the housing. A collecting cylinder is located at the front of the housing, and a motor is located on the left side of the collecting cylinder. The clamping and heat-insulating mechanism includes a fixing block, a clamping wheel, a spring, and a fixing shaft. The fixing shaft is slidably connected to the bottom of the oil tank. The clamping wheel is rotatably connected to the outer circumferential surface of the fixing shaft. The fixing block is fixedly connected to the bottom of the oil tank. One end of the spring is fixedly connected to the outer circumferential surface of the fixing shaft, and the other end of the spring is fixedly connected to the outer wall of the fixing block. The clamping and heat-insulating mechanism also includes heat-conducting rods, which are fixedly connected to the top of the clamping wheel. The clamping wheel contacts the cable. Several heat-conducting rods are evenly arrayed on top of the clamping wheel. The cable is manually inserted through the inlet, with the other end wrapped around the surface of the collecting cylinder. The motor is then started, and under its traction, the cable slides at a constant speed within the device and is finally collected by the collecting cylinder. When the cable enters through the inlet, a fixed roller limits and guides it, allowing the cable to enter the oil tank. After passing through the clamping and heat-insulating mechanism, the clamping wheel rotates due to friction under the motor's traction. Simultaneously, the heat-conducting rods on top rotate, releasing heat to prevent excessive temperature fluctuations inside the oil tank from affecting the cable's oil transfer efficiency. The rotation of the clamping wheel expands the heating range of the heat-conducting rods, increasing heating efficiency.

[0006] Preferably, the oil scraping device includes an assembly block, a limiting rod, oil scraping teeth, and a rotating shell. The assembly block is slidably connected to the outer circumferential surface of the reciprocating lead screw. The limiting rod is fixedly connected to the inner wall of the housing. The rotating shell is fixedly connected to the top of the assembly block. The oil scraping teeth are rotatably connected to the inner wall of the rotating shell. The oil scraping device also includes a transmission tooth, a return spring, a non-self-locking spiral rod, and a small transmission belt. The non-self-locking spiral rod is slidably connected to the inner wall of the assembly block. The transmission tooth is movably connected to the outer circumferential surface of the non-self-locking spiral rod. One end of the return spring is fixedly connected to the outer surface of the assembly block, and the other end of the return spring is fixedly connected to the outer wall of the transmission tooth. A gear rack is provided on the outer circumferential surface of the oil scraping tooth. The teeth of the transmission tooth and the outer circumferential surface of the oil scraping tooth are aligned. The meshing mechanism works as follows: When the cable passes the fixed roller under the traction of the motor, the friction force drives the fixed roller to rotate. As the fixed roller rotates, it drives the long convex strip to rotate via the transmission belt. The convex surface of the long convex strip contacts the cable, causing the cable to vibrate and the oil droplets on the cable surface to fall onto the lower oil guide plate and flow back into the oil tank for reuse. At the same time, as the transmission belt rotates, the drive column on the surface rotates to a certain position and drives the scraper to move from top to bottom on the plate to scrape off the oil adhering to the plate, preventing excessive oil from adhering to the plate and affecting work efficiency. When the drive column rotates to a certain angle and no longer contacts the scraper, the scraper will return to its original position under the elastic action of the tension spring, thus achieving the effect of scraping the plate surface repeatedly.

[0007] Preferably, the oil guide plate includes a plate surface, an oil scraper, a tension spring, a fixing block, a limiting strip, and a driving column. The plate surface is disposed on the inner wall of the housing, the fixing block is fixedly connected to the outer wall of the plate surface, the oil scraper is slidably connected to the outer surface of the oil scraper, the limiting strip is fixedly connected to the outer circumferential surface of the oil scraper, one end of the tension spring is fixedly connected to the outer wall of the oil scraper, and the other end of the tension spring is fixedly connected to the outer circumferential surface of the fixing block. The vibration mechanism includes a long protruding strip and a transmission belt. The long protruding strip is rotatably connected to the inside of the housing, one side of the transmission belt is drivenly connected to the outer circumferential surface of the long protruding strip, and the other side of the transmission belt is drivenly connected to the outer circumferential surface of the fixed roller. The driving column is fixedly connected to the outer circumferential surface of the transmission belt. The long protruding strip contacts the cable and contacts the non-self-locking spiral rod. The column contacts the scraper blade. When the long convex strip rotates, it contacts the non-self-locking auger during rotation, causing it to extend and retract inward. Simultaneously, the non-self-locking auger groove on the surface of the non-self-locking auger causes the transmission teeth to rotate. When the long convex strip no longer contacts the non-self-locking auger, the elasticity of the return spring causes the non-self-locking auger to return to its original position. At the same time, the rotation of the transmission teeth also drives the return spring to rotate. When the force on the return spring reaches a certain level, it will drive the transmission teeth to rotate further, thereby better driving the scraper teeth and thus improving the scraping effect on the surface of the cable. At the same time, when the long convex strip rotates, it drives the reciprocating screw to rotate through the small transmission belt. While the reciprocating screw rotates, it drives the assembly block to move back and forth. Under the limit of the limit rod, the scraper device moves back and forth, thus improving the cable collection effect and preventing the cable from accumulating in one place in the collection cylinder.

[0008] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. The oil scraping mechanism of the oil-passing device for power production, with the cooperation of the clamping wheel, heat-conducting rod, oil tank, and cable, allows the heat-conducting rod at the top to rotate simultaneously with the clamping wheel. The heat-conducting rod releases heat to prevent excessive fluctuations in the oil temperature inside the oil tank from affecting the oil-passing efficiency of the cable. The rotation of the clamping wheel expands the heating range of the heat-conducting rod, increasing the heating efficiency.

[0009] 2. The oil scraping mechanism of the oil-passing device for power production, with the cooperation of the transmission belt, drive column, scraper plate, and plate surface, drives the scraper plate to move from top to bottom on the plate surface to scrape off the oil adhering to the plate surface when the drive column rotates to a certain position while the transmission belt rotates.

[0010] 3. The oil scraping mechanism of the oil-collecting device for power production, in cooperation with the long convex bar, small transmission belt, reciprocating screw, assembly block and oil scraping device, the long convex bar drives the reciprocating screw to rotate through the small transmission belt when rotating. At the same time as the reciprocating screw rotates, it drives the assembly block to move back and forth. Under the limit of the limit rod, the oil scraping device moves back and forth, thereby improving the cable collection effect and preventing the cable from accumulating in a certain place in the collection cylinder.

The fixing shaft 304 is slidably connected to the bottom of the oil tank 11, the wire clamping wheel 302 is rotatably connected to the outer circumferential surface of the fixing shaft 304, the fixing block 301 is fixedly connected to the bottom of the oil tank 11, one end of the spring 303 is fixedly connected to the outer circumferential surface of the fixing shaft 304, and the other end of the spring 303 is fixedly connected to the outer wall of the fixing block 301. The clamping and heat-insulating mechanism 3 also includes a heat-conducting rod 305, which is fixedly connected to the top of the clamping wheel 302. The clamping wheel 302 contacts the cable 1. The clamping and heat-insulating mechanism 3 also includes a heat-conducting rod 305, which is fixedly connected to the top of the clamping wheel 302. Several heat-conducting rods 305 are provided, and the several heat-conducting rods 305 are evenly arrayed on the top of the heat-conducting rods 305. The oil scraping device 5 includes an assembly block 501, a limiting rod 502, oil scraping teeth 503, and a rotating shell 507. The assembly block 501 is slidably connected to the outer circumferential surface of the reciprocating screw 8. The limiting rod 502 is fixedly connected to the inner wall of the housing 4. The rotating shell 507 is fixedly connected to the top of the assembly block 501. The oil scraper tooth 503 is rotatably connected to the inner wall of the rotating housing 507. The oil scraper device 5 also includes a transmission tooth 504, a return spring 505, a non-self-locking spiral rod 506, and a small transmission belt 508. The non-self-locking spiral rod 506 is slidably connected to the inner wall of the assembly block 501. The transmission tooth 504 is movably connected to the outer circumferential surface of the non-self-locking spiral rod 506. One end of the return spring 505 is fixedly connected to the outer surface of the assembly block 501, and the other end of the return spring 505 is fixedly connected to the outer wall of the transmission tooth 504. A gear rack is provided on the outer circumferential surface of the oil scraper tooth 503. The transmission tooth 504 meshes with the teeth on the outer circumferential surface of the oil scraper tooth 503. The small transmission belt 508 is connected to the circumferential surface of the reciprocating screw 8.

[0015] Working principle: The cable 1 is manually inserted into the inlet 12, and the other end is wrapped around the surface of the collecting cylinder 6. Then the motor 7 is started. Under the traction of the motor 7, the cable 1 will slide at a constant speed in the device and finally be collected by the collecting cylinder 6. When the cable 1 enters from the inlet 12, it is limited and guided by the fixed roller 2, so that the cable 1 enters the oil tank 11. Then it passes through the clamping and heat preservation mechanism 3. Under the traction of the motor 7, the friction causes the clamping wheel 302 to rotate. At the same time as the clamping wheel 302 rotates, the heat conducting rod 305 on the top also rotates. The heat conducting rod 305 releases heat to prevent the oil temperature inside the oil tank 11 from changing too much and affecting the oil passing efficiency of the cable 1. The rotation of the clamping wheel 302 expands the heating range of the heat conducting rod 305 and increases the heating efficiency.

[0016] When cable 1 passes through fixed roller 2 under the traction of motor 7, it will drive fixed roller 2 to rotate through friction. When fixed roller 2 rotates, it drives long convex strip 1001 to rotate through transmission belt 1002, so that the convex surface of long convex strip 1001 contacts cable, thereby causing cable 1 to vibrate and oil droplets on the surface of cable 1 to fall onto the lower oil guide plate 9 and flow back into oil tank 11 for reuse. At the same time, when transmission belt 1002 rotates, the drive column 906 on the surface rotates to a certain position and drives the scraper 902 to move from top to bottom on plate surface 901 to scrape off the oil adhering to plate surface 901, preventing too much oil from adhering to plate surface 901 and affecting work efficiency. When drive column 906 rotates to a certain angle and no longer contacts scraper 902, scraper 902 will reset under the elastic action of tension spring 903, thus achieving the effect of scraping plate surface 901 repeatedly.

[0017] Please see Figures 1-7Based on the above embodiments, in another embodiment of the present invention, the oil guide plate 9 includes a plate surface 901, an oil scraper 902, a tension spring 903, a fixing block 904, a limiting strip 905, and a driving column 906. The plate surface 901 is disposed on the inner wall of the housing 4, the fixing block 904 is fixedly connected to the outer wall of the plate surface 901, the oil scraper 902 is slidably connected to the outer surface of the oil scraper 902, the limiting strip 905 is fixedly connected to the outer circumferential surface of the oil scraper 902, one end of the tension spring 903 is fixedly connected to the outer wall of the oil scraper 902, and the other end of the tension spring 903 is fixedly connected to the outer circumferential surface of the fixing block 904. The vibration mechanism 10 includes a long protruding strip 1001 and a transmission belt 1002. The long protruding strip 1001 is rotatably connected to the inside of the housing 4. One side of the transmission belt 1002 is connected to the outer circumferential surface of the long protruding strip 1001, and the other side of the transmission belt 1002 is connected to the outer circumferential surface of the fixed roller 2. The drive column 906 is fixedly connected to the outer circumferential surface of the transmission belt 1002. The long protruding strip 1001 is in contact with the cable 1 and the non-self-locking spiral rod 506. The drive column 906 is in contact with the oil scraper 902. The long protruding strip 1001 is in contact with the cable 1 and the non-self-locking spiral rod 506. The drive column 906 is in contact with the oil scraper 902. The outer circumferential surface of the long protruding strip 1001 is connected to the inner wall of the small transmission belt 508.

[0018] Working principle: When the long protrusion 1001 rotates, it contacts the non-self-locking spiral rod 506 during rotation, causing it to extend and retract inward. Simultaneously, the non-self-locking spiral groove on the surface of the non-self-locking spiral rod 506 causes the transmission gear 504 to rotate. When the long protrusion 1001 no longer contacts the non-self-locking spiral rod 506, the elasticity of the return spring 505 causes the non-self-locking spiral rod 506 to return to its original position. At the same time, the rotation of the transmission gear 504 also drives the return spring 505 to rotate. When the return spring 505... When the force on 05 reaches a certain level, it will drive the transmission gear 504 to rotate further, thereby better driving the oil scraping gear 503, thus achieving a better oil scraping effect on the surface of the cable 1. At the same time, when the long protrusion 1001 rotates, it drives the reciprocating screw 8 to rotate through the small transmission belt 508. While the reciprocating screw 8 rotates, it drives the assembly block 501 to move back and forth. Under the limit of the limit rod 502, the oil scraping device 5 moves back and forth, thereby achieving a better cable collection effect and preventing the cable 1 from accumulating at a certain place in the collection cylinder 6.

Many methods and approaches exist for implementing this technical solution; the above description is merely a preferred embodiment of the invention.

All components not explicitly stated in this embodiment can be implemented using existing technology.
