Description

Technical Field

[0001] This invention relates to the field of coating equipment technology, and more particularly to a graphite coating device for a 110kV high-voltage cable. Background Technology

[0002] After the production of high-voltage cables is completed, the insulation performance of the outer sheath needs to be tested before the cables leave the factory. Usually, conductive materials need to be coated on the surface of the outer sheath in advance. This is mainly because the good lubrication properties of graphite powder reduce the friction on the cable surface when the cable is laid, thereby reducing the probability of damage to the cable insulation layer and improving the performance of the cable. As a result, the application of cable graphite coating equipment covers many fields such as communications, power, industry, and aerospace.

[0003] During the graphite coating process of high-voltage cables, uneven tension during cable laying or winding can cause significant cable fluctuations. This cable swaying can lead to coating eccentricity and uneven coating. Furthermore, residual moisture, oil, or dust on the cable surface can affect wettability, also resulting in uneven coating and ultimately impacting the cable's shielding performance and electrical safety. Summary of the Invention

[0004] The purpose of this invention is to address the problems encountered during graphite coating of high-voltage cables. These problems include uneven tension during wire release or take-up, which causes significant cable fluctuations and eccentric coating due to cable swaying. Additionally, residual moisture, oil, or dust on the cable surface affects wettability and also leads to uneven coating, thus impacting the cable's shielding performance and electrical safety. Therefore, this invention proposes a graphite coating device for 110kV high-voltage cables.

[0005] To achieve the above objectives, the present invention employs the following technology: a graphite coating device for a 110kV high-voltage cable.

On both sides of the coating and drying component, a correction component is fixed on the frame, and a cleaning component is installed on one side of one of the correction components.

[0007] The correction component includes a connecting plate two fixed to the frame, two symmetrical support plates fixed on the connecting plate two, a circular plate one fixed on one side of the two support plates that are close to each other, a V-shaped guide wheel one rotatably installed between the two circular plates one, a plurality of annular array extrusion strips one fixed on the outer surface of the V-shaped guide wheel one, a connecting shaft penetrating the support plate fixed on one side of the V-shaped guide wheel one, a cylinder fixed on one side of one of the support plates, a connecting rod assembly one fixed at the output end of the cylinder, a connecting rod assembly two fixed on the circular plate one on the same side as the connecting shaft through a connecting frame, and an extrusion component jointly installed on the connecting rod assembly one and the connecting rod assembly two;

A gear is rotatably mounted on one side of the fixed frame that meshes with the two gears. Two mounting blocks that are slidably connected to the inner cavity sidewall of the fixed frame are threaded to the outer surface of each of the two bidirectional screws in the same set. A rotating roller is rotatably mounted between the two mounting blocks on the same side.

[0012] A guide component is fixed to one side of the frame near the cleaning component. The guide component includes a connecting plate that is fixedly connected to the frame. Two symmetrical mounting plates are fixed to one side of the connecting plate. A motor is fixed to one of the mounting plates. A drive gear is fixed to the output end of the motor. An annular plate is fixed to one side of each of the two mounting plates. Four annular array grooves are opened on each of the two annular plates. Limiting components are slidably installed in the inner cavity of each of the four grooves.

[0013] Further description of a graphite coating device for a 110kV high-voltage cable as described above:

[0014] A rotating ring is rotatably mounted between the two annular plates. The rotating ring has two annular arrays of locking slots, namely, the two locking slots are in the vertical direction and the two locking slots are in the horizontal direction. A half-tooth ring that meshes with the drive gear is fixed on the outer surface of the rotating ring.

[0015] Further description of a graphite coating device for a 110kV high-voltage cable as described above:

[0016] The limiting component includes a connecting rod that is slidably installed in the inner cavity of the slide groove. Both ends of the connecting rod are fixed with U-shaped plates, and guide wheels are rotatably installed in the inner cavities of the two U-shaped plates.

[0017] Further description of a graphite coating device for a 110kV high-voltage cable as described above:

[0018] The extrusion component includes two straight plates, and a circular plate is fixed on one side of each of the two straight plates that are close to each other. A V-shaped guide wheel is rotatably installed between the two circular plates, and multiple annular arrays of extrusion strips are fixed on the outer surface of the V-shaped guide wheel.

[0019] Further description of a graphite coating device for a 110kV high-voltage cable as described above:

[0020] The cleaning component includes two L-shaped frames that are fixedly connected to a circular plate by a mounting rod. The vertical parts of the two L-shaped frames are jointly fixed with a fixing ring. An mounting tube is rotatably installed in the inner cavity of the fixing ring. Multiple spiral strips in an annular array are fixed on the inner surface of the mounting tube. A bevel gear ring is fixed at one end of the mounting tube.

[0021] Further description of a graphite coating device for a 110kV high-voltage cable as described above:

[0022] The coating and drying component includes a connecting frame, a coating and drying box is fixed to one side of the connecting frame, the inner cavity of the coating and drying box is divided into a spraying chamber and a drying chamber, a graphite liquid stirring tank is fixed on the connecting frame, and a hot air generator is fixed to one side of the coating and drying box.

[0023] In summary, the beneficial effects of this invention, which employs the aforementioned technology to create a graphite coating device for a 110kV high-voltage cable, are as follows:

[0024] 1. This device, through the cooperation of two correction components and a cleaning component, ensures that the cable remains taut as it passes through the inner cavity of the coating and drying component, resulting in uniform cable stress, preventing cable fluctuations, and thus ensuring a uniform cable coating. Simultaneously, it cleans cables that do not enter the coating and drying component, removing residual moisture, oil, or dust from the cable surface, reducing the impact on wettability, and preventing uneven cable coating, thereby avoiding affecting the cable's shielding performance and electrical safety. A cylinder lowers the extrusion component, causing V-shaped guide wheels two and one to compress the cable. The cable located between the two correction components within the inner cavity of the coating and drying component remains taut under the extrusion pressure, unaffected by external forces. The friction generated by the extrusion strips on V-shaped guide wheels two and one causes V-shaped guide wheel one to rotate during cable movement, causing the connecting shaft and bevel gear to rotate together, thus rotating the mounting tube. During the rotation of the mounting tube, several spiral strips within the mounting tube clean the cable surface, and the cleaned impurities are discharged along the spiral direction of the spiral strips.

[0025] 2. This device, through the cooperation of its guiding and supporting components, not only centers and clamps the cable, but also provides phased guidance. In the vertical phase: Motor 1 drives the rotating ring, and the locking slot 1 pushes the vertical guide wheel to clamp the cable, eliminating gravity-induced sagging and keeping the cable on a horizontal reference plane. In the horizontal phase: Locking slot 2 drives the horizontal guide wheel to constrain the cable, preventing over-constraint and cable misalignment. Locking slots 1 and 2 control the guide wheel movement in a time-sharing manner, achieving conflict-free, step-by-step clamping. During the rotation of the rotating ring, the first phase of the two locking slots 1 moves the connecting rods within the corresponding slide grooves, bringing the two vertical limiting components closer together, clamping and supporting the cable vertically. Simultaneously, the first phase of the two locking slots 2 stabilizes the connecting rods within the corresponding slide grooves, and the second phase of the two locking slots 1 stabilizes the connecting rods within the corresponding slide grooves. This, in turn, brings the two horizontal limiting components closer together, constraining the cable's lateral misalignment.

[0026] 3. When the cable passes through the support component, by rotating the first gear in the vertical and horizontal directions, in conjunction with the second gear, the two sets of bidirectional screws rotate simultaneously, thereby bringing the two vertical rotating rollers and the two horizontal rotating rollers closer to each other, thus clamping the cable in a centered manner.

[0046] The following will describe in detail, with reference to the accompanying drawings of the embodiments of the present invention, a graphite coating device for a 110kV high-voltage cable according to the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0047] Example 1

[0048] like Figure 1 and Figure 2 As shown, a graphite coating device for a 110kV high-voltage cable includes a frame 10, which is the prior art. Two symmetrical support components 20 are fixed on one side of the frame 10. The two support components 20 are located at both ends of the frame 10 and are used to support the cable passing through. A coating and drying component 60 is fixed in the middle of one side of the frame 10. The coating and drying component 60 is used to spray graphite liquid onto the cable and dry the coated cable. On both sides of the coating and drying component 60, there are two correction components 50 fixed on the frame 10 and are located on both sides of the coating and drying component 60 and are used to clamp the cable.

[0049] One of the correction components 50 has a cleaning component 40 installed on one side. The cleaning component 40 is installed on the side where the cable enters and acts on the uncoated cable surface to clean the cable. A guide component 30 is fixed on one side of the frame 10 near the cleaning component 40. The guide component 30 is used to support and position the cable.

[0050] Furthermore, such as Figure 3As shown, the support component 20 includes a fixed frame 21 fixedly connected to the frame 10 via a mounting frame. The mounting frame is fixed to the frame 10, and the fixed frame 21 is fixed to the mounting frame. Two sets of mutually perpendicular bidirectional screws 22 are rotatably mounted on the fixed frame 21. The two sets of bidirectional screws 22 are located in different positions. One set of bidirectional screws 22 is horizontal, and the other set is vertical. The bidirectional screws 22 are rotatably mounted through the fixed frame 21, and the spiral part is located in the inner cavity of the fixed frame 21. One end of each of the two bidirectional screws 22 in the same set is fixed with a gear 23. A set of bidirectional screws 22 consists of two parallel bidirectional screws 22. The end of the bidirectional screw 22 located outside the fixed frame 21 is fixedly connected to the gear 23. One of the gears 23 is fixed with a rotating rod, which can control the rotation of the gear 23.

[0051] Next, a gear 24 meshes with two gears 23 on one side of the fixed frame 21. Through the two gears 23 and the gear 24, the two gears 23 rotate in the same direction. The outer surfaces of the two bidirectional screws 22 in the same group are threaded with two mounting blocks 26 that are slidably connected to the inner cavity sidewall of the fixed frame 21. The two mounting blocks 26 on the outer surface of one bidirectional screw 22 are symmetrical. A rotating roller 25 is rotatably installed between the two mounting blocks 26 on the same side. A rotating roller 25 is rotatably installed between the two corresponding mounting blocks 26 on the two bidirectional screws 22.

[0052] By rotating the vertical and horizontal gears 23, the two sets of bidirectional screws 22 are rotated, causing the two mounting blocks 26 connected to the bidirectional screws 22 to move away from or towards each other. This allows the four rotating rollers 25 to be centered and clamped to support the cable and position it in the corresponding position, preventing initial cable deviation.

[0053] Furthermore, such as Figures 4-6 As shown, the guide component 30 includes a connecting plate 31 fixedly connected to the frame 10. Two symmetrical mounting plates are fixed on one side of the connecting plate 31. A motor 32 is fixed on one of the mounting plates. A drive gear 321 is fixed at the output end of the motor 32. An annular plate 34 is fixed on one side of each of the two mounting plates. Four annular array grooves 35 are opened on each of the two annular plates 34. Limiting components 33 are slidably installed in the inner cavity of each of the four grooves 35. A limiting component 33 is installed in the inner cavity of each of the two corresponding grooves 35 on the two annular plates 34. That is, the limiting components 33 are installed in the inner cavity of each of the four grooves 35 on the annular plate 34. The limiting components 33 are used to clamp and guide the cable.

[0054] Next, a rotating ring 36 is rotatably installed between the two annular plates 34. The rotating ring 36 has two annular array of locking slots 37 and 38. The two locking slots 37 are in the vertical direction and correspond to the two vertical sliding grooves 35 on the annular plate 34. The two locking slots 38 are in the horizontal direction and correspond to the two horizontal sliding grooves 35 on the annular plate 34. A half-tooth ring 39 that meshes with the drive gear 321 is fixed on the outer surface of the rotating ring 36. The drive gear 321 causes the half-tooth ring 39 to rotate with the rotating ring 36, so that the locking slots 37 and 38 on the rotating ring 36 act on the limiting component 33 in stages, causing the limiting component 33 to move in stages. First, the two limiting components 33 in the vertical direction move closer to each other to solve the problem of cable sag due to gravity and control the cable on the horizontal reference plane. Then, the two limiting components 33 in the horizontal direction move closer to each other to constrain the cable from shifting left and right.

[0055] Both slot 1 (37) and slot 2 (38) can be divided into two sections, such as... Figure 7 As shown, during the rotation of the rotating ring 36, the first stage of the two locking grooves 37 allows the limiting components 33 in the corresponding inner cavity of the slide groove 35 to move, causing the two limiting components 33 to move closer to each other and clamp and support the cable in the vertical direction. At this time, the first stage of the two locking grooves 38 keeps the limiting components 33 in the corresponding inner cavity of the slide groove 35 stable, as shown. Figure 8 As shown, in the second stage, the two locking slots 37 keep the limiting components 33 in the inner cavity of the corresponding slide groove 35 stable. At this time, in the second stage, the two locking slots 38 bring the limiting components 33 in the inner cavity of the corresponding slide groove 35 closer to each other, so that the two limiting components 33 in the horizontal direction are close together, thus constraining the left and right offset of the cable.

[0056] Step-by-step guidance can avoid over-constraint. If all four wheels are in contact with the cable at the same time, even a slight misalignment will generate internal stress, causing damage to the cable surface. In the first stage, the two vertical wheels mainly solve the problem of gravity sag and keep the cable on the horizontal reference plane. Only in the second stage do the two horizontal wheels begin to constrain left and right offsets.

[0057] Furthermore, such as Figure 5 As shown, the limiting component 33 includes a connecting rod 331 that is slidably installed in the inner cavity of the slide groove 35. The connecting rod 331 is located in the inner cavities of the corresponding two slide grooves 35 of the two annular plates 34. Both ends of the connecting rod 331 are fixed with U-shaped plates 332. The U-shaped plates 332 are in close contact with the annular plates 34 on the same side. The inner cavities of the two U-shaped plates 332 are rotatably installed with guide wheels 333. The guide wheels 333 are used to support the cable and guide the cable.

[0058] Example 2

[0059] This embodiment further defines the cleaning component 40 and the correction component 50 based on Embodiment 1, in order to prevent uneven wire feeding or take-up.

[0060] Specifically, such as Figure 9 and Figure 10 As shown, the correction component 50 includes a connecting plate 2 51 fixed to the frame 10. Two symmetrical support plates 52 are fixed on the connecting plate 2 51. A circular plate 53 is fixed to one side of each support plate 52 that is close to each other. A V-shaped guide wheel 54 is rotatably mounted between the two circular plates 53. The V-shaped guide wheel 54 supports the cable. Several annular arrays of extrusion strips 55 are fixed to the outer surface of the V-shaped guide wheel 54. The extrusion strips 55 are made of silicone and have raised dots on their surface to increase friction. A connecting shaft 541 is fixed to one side of the V-shaped guide wheel 54, penetrating the support plate 52. The connecting shaft 541 is rotatably connected to the support plate 52 at the penetration point.

[0061] Next, a cylinder 56 is fixed on one side of one of the support plates 52, and a cylinder 56 is fixed on the support plate 52 on the side away from the connecting shaft 541. A connecting rod assembly 1 57 is fixed at the output end of the cylinder 56. The connecting rod assembly 1 57 includes a base plate, a fixed rod, a connecting spring, and a top plate. The connecting spring is fixed on the base plate. A connecting rod assembly 2 58 is fixed on the circular plate 1 53 on the same side as the connecting shaft 541 through a connecting bracket. The connecting bracket is fixed on the circular plate 1 53. The connecting rod assembly 2 58 also includes a base plate, a fixed rod, a connecting spring, and a top plate. The connecting spring is fixed on the base plate. A pressing component 59 is installed on both the connecting rod assembly 1 57 and the connecting rod assembly 2 58. The pressing component 59 is slidably installed on the fixed rod in the connecting rod assembly 1 57 and the connecting rod assembly 2 58.

[0062] Furthermore, such as Figure 10 As shown, the extrusion component 59 includes two straight plates 591. The fixing rods in the first connecting rod assembly 57 and the second connecting rod assembly 58 respectively pass through the two straight plates 591, and the straight plates 591 are connected to the connecting springs in the first connecting rod assembly 57 and the second connecting rod assembly 58. The top plate is used to limit the movement position of the straight plates 591. A circular plate 592 is fixed on the side of the two straight plates 591 that are close to each other. A V-shaped guide wheel 593 is rotatably installed between the two circular plates 592. A plurality of extrusion strips in an annular array are fixed on the outer surface of the V-shaped guide wheel 593. The extrusion bar 2594 has the same structure as the extrusion bar 155. The extrusion component 59 can be moved up and down by the cylinder 56, the connecting rod assembly 157 and the connecting rod assembly 258, so that the V-shaped guide wheel 154 and the extrusion bar 2594 clamp the cable. When the cable is retracted, the extrusion bar 155 on the V-shaped guide wheel 154 and the extrusion bar 2594 on the V-shaped guide wheel 2593 squeeze the cable. Under the action of friction, the cable can move and drive the V-shaped guide wheel 2593 and the V-shaped guide wheel 154 to rotate.

[0063] Two correction components 50 keep the cable taut as it passes through the inner cavity of the coating and drying component 60, ensuring uniform stress on the cable, preventing cable fluctuations, and thus ensuring a uniform cable coating.

[0064] Furthermore, such as Figure 11 As shown, the cleaning component 40 includes two L-shaped frames 41 that are fixedly connected to the circular plate 53 via mounting rods. The L-shaped frames 41 are fixedly connected to the circular plate 53 on the same side via mounting rods. The vertical parts of the two L-shaped frames 41 are jointly fixed with a fixing ring 42. An installation tube 44 is rotatably installed in the inner cavity of the fixing ring 42. Multiple annular array spiral strips 43 are fixed on the inner surface of the installation tube 44. The spiral strips 43 are in close contact with the cable surface. During the rotation of the installation tube 44 with the spiral strips 43, the dust and impurities on the cable can be cleaned off and discharged along the spiral direction of the spiral strips 43, without causing secondary pollution.

[0065] One end of the mounting tube 44 is fixed with a bevel gear ring 45. A bevel gear 46 that meshes with the bevel gear ring 45 is rotatably mounted on the horizontal part of one of the L-shaped brackets 41. The bevel gear 46 and the connecting shaft 541 are connected by a pulley set. A pulley is fixed on the mounting shaft of the bevel gear 46 and a pulley is also fixed on the connecting shaft 541. A pulley is wound on the two pulleys, so that the bevel gear 46 and the connecting shaft 541 rotate together, thereby rotating the bevel gear ring 45. As the V-shaped guide wheel 54 rotates, the bevel gear ring 45 rotates the mounting tube 44, so that the spiral strip 43 inside the mounting tube 44 cleans the cable.

[0066] Furthermore, such as Figure 12 As shown, the coating and drying component 60 includes a connecting frame 61, which is fixedly connected to the frame 10. A coating and drying chamber 62 is fixed to one side of the connecting frame 61. The inner cavity of the coating and drying chamber 62 is divided into a spraying chamber and a drying chamber. An adjustable spray gun head is installed in the spraying chamber for spraying graphite liquid onto the cable. A graphite liquid stirring tank 63 is fixed on the connecting frame 61 for preparing graphite liquid. A hot air generator 64 is fixed to one side of the coating and drying chamber 62 for supplying hot air to the drying chamber inside the coating and drying chamber 62 to dry the sprayed cable.

[0067] It should be noted that the frame 10, bidirectional screw 22, motor 32, cylinder 56, coating drying oven 62, graphite liquid stirring tank 63, and hot gas generator 64 in this invention are all existing technologies, and their installation methods and control methods are also conventional designs, which will not be described in detail in this invention.

[0068] The working principle of this invention: Through the cooperation between the guide component 30 and the support component 20, this device can not only center and clamp the cable, but also guide it in stages. In the first stage, the two vertical wheels mainly solve the problem of gravity sag and control the cable on the horizontal reference plane. In the second stage, the two horizontal wheels begin to constrain the left and right offset, so as to avoid over-constraining the cable and causing the cable to deviate.

[0069] During use, the cable is pulled by the traction device and passes through the support component 20, guide component 30, cleaning component 40, correction component 50, coating and drying component 60, correction component 50 and support component 20 in sequence. When the cable passes through the support component 20, the vertical and horizontal gears 23 are rotated in conjunction with the gear 24, so that the two sets of bidirectional screws 22 rotate simultaneously, thereby bringing the two vertical rotating rollers 25 and the two horizontal rotating rollers 25 closer to each other, thereby centering and clamping the cable.

[0070] Next, by controlling motor 32, the drive gear 321 engages with the half-gear ring 39 to rotate the rotating ring 36. During the rotation of the rotating ring 36, as... Figure 7 As shown, the first stage of the two locking slots 37 allows the connecting rod 331 of the corresponding inner cavity of the slide groove 35 to move, causing the two limiting components 33 in the vertical direction to move closer to each other, clamping and supporting the cable in the vertical direction. At this time, the first stage of the two locking slots 38 keeps the connecting rod 331 of the corresponding inner cavity of the slide groove 35 stable, as shown. Figure 8 As shown, in the second stage of the two locking slots 37, the connecting rod 331 in the inner cavity of the corresponding slide groove 35 is kept stable. At this time, in the second stage of the two locking slots 38, the connecting rod 331 in the inner cavity of the corresponding slide groove 35 is brought closer to each other, and the two limiting components 33 in the horizontal direction are brought closer to each other, thus constraining the left and right displacement of the cable.

[0071] This device, through the cooperation between the two correction components 50 and the cleaning component 40, can keep the cable taut when it passes through the inner cavity of the coating and drying component 60, so that the cable is subjected to uniform force and avoids cable fluctuation, thereby making the cable coating uniform. At the same time, it can clean the cable that has not entered the coating and drying component 60, remove residual moisture, oil or dust from the cable surface, reduce the impact of wettability, and make the cable coating uneven, thus avoiding affecting the shielding performance and electrical safety of the cable.

[0072] Specifically, when the cable passes through the correction component 50, the connecting rod assembly 57 controlled by the cylinder 56 moves the pressing component 59, so that the cable is located on the outer surface of the V-shaped guide wheel 54. Then, the pressing component 59 is lowered by the cylinder 56, so that the V-shaped guide wheel 593 and the V-shaped guide wheel 54 press the cable. The cable located in the inner cavity of the coating and drying component 60 between the two correction components 50 remains taut under the action of the pressing force and is not affected by external forces. When the cable is pulled, the pressing strip 594 on the V-shaped guide wheel 593 and the pressing strip 55 on the V-shaped guide wheel 54 generate friction force on the cable, so that the V-shaped guide wheel 54 rotates along with the cable during the movement of the cable, thereby causing the connecting shaft 541 to rotate.

[0073] Since the connecting shaft 541 and the bevel gear 46 mounting shaft are connected by a belt, the bevel gear 46 drives the bevel gear ring 45 to rotate, thereby causing the mounting tube 44 to rotate. During the rotation of the mounting tube 44, several spiral strips 43 in the inner cavity of the mounting tube 44 clean the cable surface, and the impurities cleaned are discharged along the spiral direction of the spiral strips 43.

[0074] When the cable passes through the inner cavity of the coating and drying component 60, graphite liquid is first sprayed onto the surface of the cable in the spraying chamber by the spray gun head, and then it enters the drying chamber for drying.

[0075] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technology of the present invention and the graphite coating device for high voltage 110kV cable and its inventive concept, should be covered within the scope of protection of the present invention.
