Description

Technical Field

[0001] This application relates to the field of power engineering technology, and in particular to a cable lead sealing device and a cable lead sealing method. Background Technology

[0002] At cable joints, lead sealing is required to prevent moisture, dampness, and dust from entering the joint. Currently, the lead sealing methods for cable joints are mostly described in the article "Delta Power Technology" (2014, Issue 5), pages 141-142: lead contact or lead casting. Both lead contact and lead casting methods require manual lead enamel application, which is labor-intensive and inefficient.

[0003] Chinese utility model patent CN216121588U discloses a rapid fixing mold for lead-sealing and welding of cable sheaths. The mold comprises an upper mold and a lower mold, hinged on one side and detachably connected on the other. The mold cavity formed by the upper and lower molds allows the cable to be sealed to pass through. Molten lead is poured into the cavity and allowed to solidify to form the lead-sealed body. Finally, the upper and lower molds are removed to complete the operation. However, the porosity of the lead-sealed body formed using this method is greater than that formed by manual lead plating. The specific reason is that the lead-sealed body is thicker. Manual lead plating is done by applying lead layer by layer, with the lead thickness gradually increasing from thin to thick. Each lead layer is relatively thin, allowing the gas generated during solidification to escape fully. However, in mold casting, the entire thickness of molten lead is filled in one go. The gas escaping path of the solidified inner sealing lead body is blocked by the rapidly solidifying outer sealing lead body, preventing gas escape and ultimately resulting in high porosity in the sealing lead body. Cable sealing lead bodies are not allowed to have high porosity because porosity would impair the sealing, conductivity, and mechanical protection functions of the sealing lead body, threatening the safe operation of the cable.

[0019] The cable lead sealing device of this application is used to seal 1000 cables with lead, such as Figures 1 to 7As shown, a preferred embodiment of the cable lead sealing device of this application includes a mounting frame 1, a rotating component 2, a first drive mechanism 3, a second drive mechanism 4, a third drive mechanism 5, and a lead coating device 6. A cable 1000 is mounted on the mounting frame 1. The rotating component 2 is connected to the mounting frame 1 and spaced apart from the cable 1000. The first drive mechanism 3 connects the mounting frame 1 and the rotating component 2. The second drive mechanism 4 is connected to the rotating component 2, and the third drive mechanism 5 is connected to the second drive mechanism 4. The lead coating device 6 is connected to the third drive mechanism 5. The first drive mechanism 3 is configured to drive the rotating component 2 to rotate about the axis of the cable 1000. The second drive mechanism 4 is configured to drive the third drive mechanism 5 to move in one of the axial and radial directions of the cable 1000. The drive mechanism 5 is configured to drive the lead coating device 6 to move along one of the axial and radial directions of the cable 1000. By adjusting the radial distance between the lead coating device 6 and the cable 1000 through one of the first drive mechanism 3 and the second drive mechanism 4, the thickness of the single-layer lead sealing layer can be adjusted. By driving the lead coating device 6 to rotate and move around the axial direction of the cable 1000 through the other of the first drive mechanism 3 and the second drive mechanism 4, as well as the first drive mechanism 3, multiple layers of lead sealing can be applied to the outer periphery of the cable 1000. The gas generated during the solidification of the lead paste of each layer of lead sealing can be fully released, which solves the problem that the gas cannot be released due to the one-time filling in the existing mold casting process, and reduces the porosity of the final lead sealing body.

[0020] In some embodiments of this application, the first driving mechanism 3 includes a gear ring 31, a first gear 32, and a first motor 33. The gear ring 31 is connected to the mounting bracket 1 and has a first wire hole. The cable 1000 is disposed in the first wire hole. The first motor 33 is connected to the rotating member 2, and the first gear 32 is connected to the output shaft of the first motor 33. The first gear 32 meshes with the gear ring 31. The first motor 33 drives the first gear 32 to rotate, while the gear ring 31 remains fixed. Therefore, the first gear 32 can drive the rotating member 2 to move along the annular guide structure. The rotating member 2 drives the lead coating device 6 to rotate around the axis of the wire hole.

[0021] The lead coating device 6 is a device that can heat raw materials such as lead powder or lead granules into lead paste and extrude the lead paste. It has heating and extrusion functions. Its structure is similar to the temperature control and extrusion mechanism of an injection molding machine. The lead coating device 6 includes a lead melting part and a lead outlet nozzle. The lead melting part is connected to the second drive mechanism 4, and the lead outlet nozzle is arranged facing the cable 1000. The lead coating device 6 can adjust the extrusion temperature and extrusion speed of the lead paste. In conjunction with the rotation speed of the rotating part 2, the lead paste is evenly applied to the outside of the cable 1000 located in the wire hole.

[0022] In some embodiments of this application, the toothed ring 31 includes a first half-toothed ring 311 and a second half-toothed ring 312. The first half-toothed ring 311 and the second half-toothed ring 312 are detachably connected. Disassembling the first half-toothed ring 311 and the second half-toothed ring 312 allows the cable 1000 to exit the first through-hole. The first half-toothed ring 311 and / or the second half-toothed ring 312 are connected to the mounting bracket 1. By disassembling the first half-toothed ring 311 and the second half-toothed ring 312, the cable 1000 can be inserted into the first through-hole. After the cable 1000 is inserted into the first through-hole, the first half-toothed ring 311 and the second half-toothed ring 312 are then connected.

[0023] In some embodiments of this application, such as Figure 1 , Figure 4 As shown, the mounting frame 1 includes a connecting frame 11 and a support member 12. The connecting frame 11 is detachably connected to the cable 1000. Using the cable 1000 as the supporting base of the connecting frame 11, the cable lead sealing device can be suspended in the air, enabling lead sealing operations on the cable 1000 at a higher position. The support member 12 has a second through hole 121, which is coaxial with the first through hole. The cable 1000 is disposed in the second through hole 121. The support member 12 includes a first semi-ring 122 and a second semi-ring 123 that are detachably connected and form the second through hole 121. The first semi-ring 122 has a first semi-circular shape. The guide structure 1223 includes a second semi-annular guide structure 1231 on the second semi-annular body 122. The first semi-gear ring 311 is connected to the first semi-annular body 122, and the second semi-gear ring 312 is connected to the second semi-annular body 123. When the first semi-annular body 122 and the second semi-annular body 123 are connected, the first semi-annular guide structure 1223 and the second semi-annular guide structure 1231 form an annular guide structure. The first semi-gear ring 311 and the second semi-gear ring 312 form the gear ring 31. The rotating member 2 is slidably connected to the annular guide structure, thereby ensuring the stable rotation of the rotating member 2 on the support member 12.

[0024] Specifically, the connecting frame 11 is detachably connected to the outside of the cable 1000 via two clamping assemblies. The two clamping assemblies are spaced apart along the length of the cable 1000. The support member 12 and the rotating member 2 are arranged between the two clamps. When the connecting frame 11 is connected to the outside of the cable 1000, the docking part of the cable 1000 is set between the two clamping assemblies. The cables 1000 at both ends of the docking part are fixed in the two clamping assemblies respectively. The inner holes of the two clamping assemblies are arranged coaxially with the wire hole. By clamping the cable 1000 in the clamping assemblies, the cable 1000 is made coaxial with the wire hole, thus achieving the positioning of the cable 1000 in the wire hole.

[0025] In some embodiments of this application, one side of the first semi-ring 122 and one side of the second semi-ring 123 are hinged, and the other side of the first semi-ring 122 and the other side of the second semi-ring 123 are detachably connected; the first semi-ring 122 is connected to the connecting frame 11.

[0026] Specifically, the second semi-ring 123 and the first semi-ring 122 are arranged vertically opposite each other. The lower part of the first semi-ring 122 is fixed on the support member 12. The first semi-ring guide structure 1223 and the second semi-ring guide structure 1231 can be guide grooves or guide posts. The rotating member 2 includes a mounting part 21 and a guide part 22 connected to the mounting part 21. The guide part 22 is slidably disposed in the guide groove or slidably sleeved on the outside of the guide post.

[0027] In some embodiments of this application, the first semi-annular guide structure 1223 and the second semi-annular guide structure 1231 are both grooves with a T-shaped cross-section. In some embodiments of this application, such as... Figure 6 As shown, the first semi-annular guide structure 1223 includes a first semi-annular groove 12221 and a second semi-annular groove. The first semi-annular body 122 includes a first body portion and a first protrusion 1222. The first protrusion 1222 protrudes from the first body portion in the axial direction of the cable 1000. The first semi-annular groove 12221 is disposed in the first protrusion 1222. The groove depth direction of the first semi-annular groove 12221 is arranged along the radial direction of the cable 1000. The second semi-annular groove is disposed in the first body portion. The groove depth direction of the second semi-annular groove is arranged along the axial direction of the cable 1000. The guide portion 22 includes a guide body 221, a first guide portion 222, and a second guide portion 223. The first guide portion 222 is slidably disposed in the first semi-annular groove 12221, and the second guide portion 223 is slidably disposed in the second semi-annular groove. The first semi-annular groove 12221 and the second semi-annular groove form the first semi-annular guide structure 1223. The structure of the second semi-annular body 123 is the same as that of the first semi-annular body 122. The second semi-annular body 123 has a third semi-annular groove 12311 and a fourth semi-annular groove 12312. The third semi-annular groove 12311 is arranged correspondingly to the first semi-annular groove 12221, and the fourth semi-annular groove 12312 is arranged correspondingly to the second semi-annular groove. The third semi-annular groove 12311 and the fourth semi-annular groove 12312 form the second semi-annular guide structure 1231.

[0028] The other side of the first half-ring 122 and the non-hinged side of the second half-ring 123 are detachably connected by a snap-fit ​​or fastener. The connection state of the first half-ring and the second half-ring mentioned in this application refers to the connection state of the non-hinged sides of the first half-ring 122 and the second half-ring 123. The separation state of the first half-ring and the second half-ring mentioned in this application refers to the separation state of the non-hinged sides of the first half-ring 122 and the second half-ring 123. Before connecting the connecting frame 11 to the cable 1000, the first half-ring 122 and the second half-ring 123 are separated. After connecting the connecting frame 11 to the cable 1000, the first half-ring 122 and the second half-ring 123 are then connected. In other embodiments of this application, both sides of the first half-ring 122 and both sides of the second half-ring 123 are connected by fasteners or snap-fit.

[0029] The first gear 32 is connected to the output shaft of the first motor 33. In some embodiments of this application, such as... Figures 3 to 6 As shown, the cable lead sealing device further includes a first positive current collector 71, a second positive current collector 72, a first negative current collector 73, a second negative current collector 74, a positive conductive element 75, and a negative conductive element 76; the first positive current collector 71 and the first negative current collector 73 are connected to the first semi-ring 122, and the second positive current collector 72 and the second negative current collector 74 are connected to the second semi-ring 123; when the first semi-ring 122 and the second semi-ring 123 are connected, the first positive current collector 71 and the second positive current collector 72... A positive current collector ring, a first negative current collector 73, and a second negative current collector 74 are combined to form a negative current collector ring; a positive conductive element 75 is connected to the rotating element 2, one end of the positive conductive element 75 slides against the positive current collector ring, and the other end of the positive conductive element 75 is electrically connected to the first driving mechanism 3 and the second driving mechanism 4; a negative conductive element 76 is connected to the rotating element 2, one end of the negative conductive element 76 slides against the negative current collector ring, and the other end of the negative conductive element 76 is electrically connected to the first driving mechanism 3 and the second driving mechanism 4. Specifically, the positive collector ring is connected to the positive terminal of the power supply, and the negative collector ring is connected to the negative terminal of the power supply. When the rotating part 2 rotates, the positive conductive part 75 and the negative conductive part 76 fixed on the rotating part 2 rotate synchronously with the rotating part 2. The positive conductive part 75 slides against the positive collector ring, and the positive terminal of the power supply is electrically connected to the positive conductive part 75 through the positive collector ring. The negative conductive part 76 slides against the negative collector ring, and the negative terminal of the power supply is electrically connected to the negative conductive part 76 through the negative collector ring. The electrical device arranged on the rotating part 2 draws power through the positive conductive part 75 and the negative conductive part 76, without the need to connect to the power supply through wires, thus avoiding the wire tangling caused by the rotation of the rotating part 2.

[0030] In some embodiments of this application, such as Figure 2As shown, the second driving mechanism 4 includes a first sliding member 41 and a first driving member 42; the first sliding member 41 is slidably connected to the rotating member 2, and the first driving member 42 connects the first sliding member 41 and the rotating member 2 to drive the first sliding member 41 to move radially along the cable 1000; the third driving mechanism 5 is connected to the first sliding member 41. The first driving member 42 is an electric telescopic rod, and the first sliding member 41 is slidably connected to the rotating member 2 via a guide post slider. The first sliding member 41 moves radially along the cable 1000 to adjust the thickness of each lead sealing layer.

[0031] In some embodiments of this application, such as Figure 3 As shown, the third driving mechanism 5 includes a second sliding member 51 and a second driving member 52; the second sliding member 51 is slidably connected to the first sliding member 41, and the second driving member 52 connects the second sliding member 51 and the first sliding member 41 to drive the second sliding member 51 to move axially along the cable 1000; the lead coating device 6 is connected to the second sliding member 51. The second sliding member 51 moves axially along the cable 1000 so that the entire length of the joint of the cable 1000 can be covered by the lead sealing layer, ensuring that the final formed lead sealing body meets the dimensional requirements in the length direction of the cable 1000. The second driving member 52 also adopts an electric telescopic rod.

[0032] Both the first driving member 42 and the second driving member 52 are electrically connected to the positive conductive member 75 and the negative conductive member 76. In other embodiments of this application, the first sliding member 41 can be configured to move axially along the cable 1000, and the second sliding member 51 can be configured to move radially along the cable 1000.

[0033] In some embodiments of this application, such as Figure 2As shown, the first sliding member 41 includes a sliding member body 411, a first guide post 412, and a second guide post 413. The sliding member body 411 is slidably connected to the rotating member 2. The first guide post 412 and the second guide post 413 are both fixed to the sliding member body 411. The first guide post 412 and the second guide post 413 are arranged in parallel and spaced apart, and both extend along the axial direction of the cable 1000. The second sliding member 51 is slidably connected to the first guide post 412 and the second guide post 413. The axis of the second driving member 52, the axis of the first guide post 412, and the axis of the second guide post 413 are parallel to each other and coplanar. Moreover, the distance between the second driving member 52 and the first guide post 412 is equal to the distance between the second driving member 52 and the second guide post 413. This configuration ensures that the push and pull applied by the second drive member 52 to the second slider 51 completely forms the thrust that moves the second slider 51, without generating torque or bending moment between the second slider and the first guide post 412 and the second guide post 413, thus guaranteeing smooth movement of the second slider 51 on the first guide post 412 and the second guide post 413.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

The first drive mechanism 3 can drive the rotating component 2 to rotate around the axis of the cable 1000, and the first drive mechanism 3 and the second drive mechanism 4 can drive the lead coating device 6. Moving axially and radially along the cable 1000, the radial distance between the lead coating device 6 and the cable 1000 can be adjusted by one of the first drive mechanism 3 and the second drive mechanism 4, thereby adjusting the thickness of a single layer of lead sealing. By rotating the lead coating device 6 and moving it axially around the cable 1000 through the other of the first drive mechanism 3 and the second drive mechanism 4, as well as the first drive mechanism 3, multiple layers of lead sealing can be applied to the outer periphery of the cable 1000. The gas generated during the solidification of the lead slurry of each layer of lead sealing can be fully released, solving the problem that the gas cannot be released due to one-time filling in the existing mold casting process, and reducing the porosity of the final lead sealing body.

[0036] This application also provides an embodiment of a cable lead sealing method, which uses the above-described cable lead sealing device and includes the following steps: Step S1: Connect the mounting bracket 1 to the outside of the cable 1000, so that the lead coating device 6 is located at the joint of the cable 1000. Step S2: The lead coating device 6 is driven to move radially and axially along the cable 1000 using the second drive mechanism 4 and the third drive mechanism 5. The second drive mechanism 4, the third drive mechanism 5, and the lead coating device 6 are driven to rotate axially around the cable 1000 using the first drive mechanism 3, applying the first layer of lead sealant to the outside of the mating area. The lead coating device 6 is driven to move radially along the cable 1000 using the second drive mechanism 4, which can adjust the thickness of the first layer of lead sealant. The lead coating device 6 is driven to move axially along the cable 1000 using the third drive mechanism 5, which ensures that the first layer of lead sealant completely covers the mating area along the length of the cable 1000. If the entire cross-section of the mating area is completely uniform along the length of the cable 1000, it is only necessary to use the second drive mechanism 4 before applying the first layer of lead sealant. The distance between the lead coating device 6 and the cable 1000 is adjusted to the correct position. During the application of the same layer of lead sealant, the radial distance between the lead coating device 6 and the cable 1000 is not adjusted during the rotation of the rotating part 2 and the movement of the lead coating device 6 along the axial direction of the cable 1000. For cases where the cross-section of the joint changes along the length of the cable 1000, such as when the joint includes a large-diameter section, a tapered transition section, and a small-diameter section connected sequentially along the axial direction of the cable 1000, the distance between the lead coating device 6 and the cable 1000 is kept fixed when applying lead to the large-diameter section and the small-diameter section. When applying lead to the tapered transition section, the distance between the lead coating device 6 and the tapered transition section needs to be adjusted once for each rotation of the lead coating device 6, thereby ensuring that the thickness of the first layer of lead sealant is the same on the large-diameter section, the tapered transition section, and the small-diameter section. Step S3: After the first lead sealing layer has cured, the second drive mechanism 4 and the third drive mechanism 5 drive the lead coating device 6 to move radially and axially along the cable 1000, and the first drive mechanism 3 drives the second drive mechanism 4, the third drive mechanism 5 and the lead coating device 6 to rotate around the axial direction of the cable 1000, so as to apply the intermediate lead sealing layer on the outside of the first lead sealing layer. Step S4: Repeat step S3 until a sealing lead body is formed on the outside of the docking area; Step S5: Remove the mounting bracket 1 from the cable 1000.

[0037] Step S1 includes: Step S11, splitting the first half-ring 122 and the second half-ring 123; that is, splitting the non-hinged side of the first half-ring 122 and the second half-ring 123. After the non-hinged side is split, the second half-ring 123 is rotated, and one side of the first wire hole and the second wire hole 121 is opened, so that the cable can enter the first wire hole and the second wire hole 121 along the radial direction of the cable 1000. Step S12: Connect the mounting bracket 1 to the outside of the cable 1000; Step S13: Connect the first half-ring 122 and the second half-ring 123; Step S5 includes: Step S51: Split the first semi-ring 122 and the second semi-ring 123; Step S52: Remove the mounting bracket 1 from the cable 1000.

[0038] The above are merely preferred embodiments of this application. It should be noted that, for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this application, and these improvements and substitutions should also be considered within the scope of protection of this application.
