Description

Technical Field

[0001] The invention relates to the technical field of cable maintenance equipment, in particular to a multifunctional maintenance equipment for power station electric equipment. Background Art

[0002] In the early days of the development of the electric power industry, power stations were relatively small, power transmission distances were short, and the requirements for cables and wires were relatively simple. The conductor materials at the time mainly relied on copper and aluminum, which became the mainstream choice due to their good conductivity. The insulation layer of the cable is mostly made of rubber or simple plastic materials. This insulation method can prevent leakage to a certain extent, but it has obvious deficiencies in high temperature resistance, high voltage resistance and durability. For example, rubber insulated cables are prone to aging and cracking in a long-term high temperature environment, resulting in a decrease in insulation performance, threatening the safe operation of the power station.

[0003] With the gradual expansion of the scale of power stations, especially the construction of large hydropower stations, thermal power stations and nuclear power stations, the performance requirements for cables and wires have increased dramatically. Higher voltage levels and greater transmission capacity have become urgent issues to be solved. As a result, cross-linked polyethylene insulation technology came into being and has been widely used. XLPE has excellent electrical insulation properties and can withstand higher voltages without breakdown. At the same time, it has good thermal stability and can operate for a long time at higher temperatures, greatly improving the current carrying capacity of the cable. In terms of conductor structure, in order to reduce AC resistance loss, the compact conductor process was adopted to make the conductors more compact, reduce the gaps between conductors, and thus improve the conductivity efficiency.

[0004] During the use of wires and cables, due to length or damage problems, workers are often required to splice the joints of two cables. When splicing two cable joints, the workers first need to connect the metal wires at the two cable joints, then wrap the connection position of the wires with insulating tape, and finally wrap and wrap the two cable joints with insulating sleeves. However, this splicing and maintenance method for cables and wires is less effective. As time goes by, the adhesive on the insulating tape will gradually fail, and gaps will appear at the joints of the metal wires wrapped by the insulating tape. Dust and moisture in the external environment will enter the connection of the metal wires through the gaps, thereby causing problems such as line short circuit or increased loss of electric energy during transmission. Therefore, those skilled in the art have proposed a multifunctional maintenance device for power station power equipment to solve the above-mentioned technical problems. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a multifunctional maintenance device for power station electrical equipment, which solves the problem that dust and water vapor in the external environment enter the connection of metal wires through the gaps in the insulating tape, thereby causing line short circuit or increased loss of electric energy during transmission.

[0015] Preferably, the end support mechanism includes an upper lifting seat, and the upper lifting seat is arranged on the top of the lower supporting seat, and an annular cavity is opened in the middle of the side adjacent to the upper lifting seat and the lower supporting seat, and a rubber ring seat is arranged on the inner wall of the annular cavity, and vertical adjustment rods are arranged on both sides of the middle of the top end of the lower supporting seat, and the top end of the vertical adjustment rod passes through the upper lifting seat and extends outward, and a locking nut is threadedly connected on the vertical adjustment rod.

[0017] Preferably, the repair and shaping mechanism includes aluminum alloy fins, and a plurality of aluminum alloy fins are equidistantly fixedly connected on both sides of the middle part of the outer wall of the metal sleeve, and an acceleration cavity is formed between adjacent aluminum alloy fins. Arc-shaped metal plates are provided on both sides of the middle part of the outer wall of the metal sleeve, and the inner walls of the arc-shaped metal plates are respectively connected to the aluminum alloy fins at corresponding positions, and the interior of the arc-shaped metal plate is a hollow cavity.

[0018] Preferably, the joint seat is located in the middle of the interior of the metal sleeve, and the brightness of the metal sleeve abuts against the rubber ring seat.

[0019] Working principle: When splicing the cables of the power equipment in the power station, the staff first installs the upper lifting seat and the lower supporting seat at both ends of the overall device at the two ends of the spliced ​​cable respectively, and then puts the metal sleeve between the two into one of the cable sections, and then takes out the joint seat in the metal sleeve to complete the preparation work before the equipment is used. Then the separation repair mechanism is started. First, the staff inserts the ends of each metal wire in a section of the cable into the interior through the guide of the wire plug tube on the joint seat, and then the staff removes the outer buckle plate on the joint seat, and then the metal wire on the other section of the cable is inserted through the joint seat. The outer buckle plate and the sockets on the stepped ring plate are inserted. After the outer buckle plate is put into the other section of the cable, the staff uses tools to twist and connect the corresponding metal wires in the two sections of the cable. After the metal wires in the two sections of the cable are connected, the staff resets the outer buckle plate. While resetting, the outer buckle plate is adsorbed with the connector seat through the magnetic absorption layer thereon to ensure the sealing of the connector seat during use, so that the outer buckle plate on the connector seat seals its interior, and then the staff opens the sealing cover on the injection tube 2, and injects the melted insulation repair material into the flow cavity through the injection tube 2 on the connector seat, and then proceeds. As the insulating repair material in the flow cavity is continuously injected, the insulating repair material in the flow cavity flows into the wire insertion tube, so that the connection of the metal wire is sealed again with insulating material, and then the repair material flowing into the wire insertion tube is prevented from overflowing by the silicone countercurrent ring in the wire insertion tube. At the same time, the stepped ring plate in the socket can also prevent the overflow of the insulating repair material. After the connection of the metal wire is repaired and finalized, the staff removes the joint seat and the outer buckle plate, and then peels off the excess material at the repair site, thereby completing the separation and repair of the metal wire connection; then The sheath splicing mechanism is started. After the separation repair mechanism repairs the connection between the two sections of metal conductors, the staff moves the metal sheath inserted into the cable to the position where the two sections of the cable are connected. After the metal sheath moves to the repair position, the sealing ring seat on the installation ring seat seals both sides of the repair position. Then the staff opens the rotating cover on the injection pipe 1 and injects the melted insulation repair material into the repair cavity in the metal sheath through the rotating cover. The insulation repair material flowing in the repair cavity repairs the insulation skin part of the outer surface of the connection position of the two sections of the cable, thereby completing the splicing of the insulation sheaths after the two sections of the cable;At the same time, the end support mechanism is started, and the staff first installs the upper lifting seat on the lower supporting seat, and then squeezes the upper lifting seat to move to the lower supporting seat by turning the locking nut on the vertical adjusting rod. While the upper lifting seat approaches the lower supporting seat, it squeezes and fixes the outer wall of the cable through the rubber ring seat in the annular cavity. The above operation is repeated to fix the other section of the cable in the same way. Then the staff connects the upper lifting seat and the lower supporting seat at both ends of the cable through the horizontal adjusting rod, and fixes them through the adjusting nuts on both ends of the horizontal adjusting rod, so as to ensure that the position of the sheath splicing mechanism at the connection between the two sections of the cable to repair the outer insulation layer is in a horizontal state, and at the same time, it can also prevent its repair position from being affected by external forces, thereby completing the repair of the two sections of the cable. The end support of the cable is processed; then the repair shaping mechanism is started, and when the sheath splicing mechanism repairs the insulation layer of the outer wall of the two sections of the cable, the high temperature of the high-temperature repair material in the repair cavity is conducted to the external environment through the metal sleeve, thereby accelerating its shaping in the first step, and then the temperature of the repair cavity material is conducted to the outside and the heat is absorbed by the aluminum alloy fins outside the metal sleeve, and then conducted again to the arc-shaped metal plate on the same side, thereby expanding its heat dissipation area, and because the acceleration cavity formed between adjacent aluminum alloy fins can accelerate the speed of air passing through the external environment, the heat generated by the repair material in the repair cavity is taken away to the maximum extent by the accelerated flow of air, thereby promoting the shaping of the cable repair position. ;

[0020] The present invention provides a multifunctional maintenance device for power station power equipment. It has the following beneficial effects:

[0021] 1. The present invention can perform sealing and fixing operations on the metal wire connections in the cable in a unique manner of separation and fixing by adding and setting a separation and fixing mechanism. This method effectively avoids the problems of wire displacement and poor contact that may occur in traditional connection methods, greatly enhancing the stability and reliability of the connection. Subsequently, the connection is sealed and wrapped with the melted repair material to further strengthen the sealing of the connection, effectively prevent the intrusion of impurities such as water vapor and dust, significantly extend the service life of the cable, reduce maintenance costs and failure rates, and ensure efficient and safe power transmission.

[0022] 2. The present invention adds and sets a sheath splicing mechanism. After the cable metal conductor connection repair is completed, the melted insulating material is used to splice and repair the sheaths at the connection of the two cable sections. This method can efficiently restore the integrity of the cable sheath, effectively prevent external physical wear, chemical corrosion and humid environment from invading the inside of the cable. Moreover, this repair method can not only enhance the stability of the overall structure of the cable, but also ensure that the insulation performance of the cable is not damaged, greatly reducing the safety hazards caused by sheath damage, extending the service life of the cable, improving the safety and reliability of cable operation, and reducing the frequency and cost of cable maintenance and replacement.

[0023] 3. The present invention adds and sets an end support mechanism. When the sheath is repaired at the connection between two cable sections, the mechanism supports and fixes the two ends of the repair position to ensure that the cable is in a horizontal state. This stability ensures the accuracy of the repair operation and effectively avoids problems such as uneven distribution of repair materials or loose connections due to cable shaking and deviation. The horizontal state is conducive to the uniform flow and solidification of repair materials, improves the quality of sheath repair, and makes the repaired cable smooth in appearance and stable in structure. At the same time, it can also reduce safety hazards caused by improper repair, improve cable repair efficiency, reduce manpower and time costs, and lay the foundation for the long-term stable operation of the cable.

[0024] 4. The present invention adds and sets a repair and shaping mechanism. When repairing the joints of two sections of cable sheaths, its unique multiple heat conduction design can quickly dissipate the heat of the repair material to the external environment, effectively accelerate the shaping of the repair material, greatly shorten the repair time, and improve work efficiency. At the same time, it accelerates the air flow to take away the conducted heat, further optimizes the heat dissipation effect, and makes the shaping process more stable and reliable. This method not only ensures the strength and sealing of the sheath after repair, reduces defects caused by poor shaping, but also allows the cable to be put into use faster, reduces the thermal impact on the surrounding environment, and improves the overall performance and practicality of the cable repair process.

[0037] The separation repair mechanism includes a joint seat 16, which is arranged between the two lower supporting seats 13, a concave seat 24 is arranged on the inner side of the joint seat 16, an outer buckle plate 17 is arranged on one side of the joint seat 16, and a plurality of wire insertion tubes 26 are arranged in a circular array on the side of the joint seat 16 away from the outer buckle plate 17, and one end of the wire insertion tube 26 passes through the concave seat 24 and extends outward, a silicone countercurrent ring 27 is arranged in the middle of the inner wall of the wire insertion tube 26, and the concave seat 24, the inner wall of the joint seat 16 and the inner wall of the outer buckle plate 17 constitute a flow cavity 25.

[0038] When the separation repair mechanism is started, the staff first inserts the ends of each metal wire in a section of the cable into the interior through the guidance of the wire insertion tube 26 on the connector seat 16, and then removes the external buckle plate 17 on the connector seat 16, and then inserts the metal wire on the other section of the cable through the external buckle plate 17 and the socket 20 on the step ring plate 29. After the external buckle plate 17 is put into the other section of the cable, the staff uses tools to twist and connect the corresponding metal wires in the two sections of the cable.

[0039] The separation repair mechanism also includes an injection tube 19, which is arranged in the middle of the top end of the outer wall of the joint seat 16, and the interior of the injection tube 19 is connected to the interior of the flow cavity 25. The upper part of the injection tube 19 is threadedly connected with a sealing cover 22, and a stepped ring plate 29 is fixedly connected to the middle part of the inner side of the outer buckle plate 17. There are multiple sockets 20 in a circular array in the middle of the outer buckle plate 17 and the stepped ring plate 29, and a silicone layer 28 is arranged on the inner wall of the socket 20. There are multiple inner buckle cavities 23 in a circular array near the edge of the outer wall of the outer buckle plate 17, and a magnetic attraction layer 30 is arranged at the edge of the outer buckle plate 17.

[0040] After the metal wires in the two sections of the cable are connected, the staff will reset the outer buckle plate 17. While resetting, the outer buckle plate 17 will be adsorbed to the connector seat 16 through the magnetic attraction layer 30 thereon, so as to ensure the sealing of the connector seat 16 during use, so that the outer buckle plate 17 on the connector seat 16 will seal its interior. Then the staff will open the sealing cover 22 on the injection tube 19 and inject the melted insulation repair material into the flow cavity 25 through the injection tube 19 on the connector seat 16.

[0041] Then, the insulating repair material entering the flow cavity 25 flows into the wire insertion tube 26 as the material is continuously injected, so that the connection of the metal wire is sealed again with insulating material, and then the repair material flowing into the wire insertion tube 26 is prevented from overflowing by the silicone countercurrent ring 27 in the wire insertion tube 26. At the same time, the stepped ring plate 29 in the socket 20 can also prevent the overflow of the insulating repair material. After the connection of the metal wire is repaired and finalized, the staff removes the joint seat 16 and the outer buckle plate 17, and then peels off the excess material at the repaired part, thereby completing the separation and repair of the metal wire connection.

[0042] The sheath splicing mechanism is arranged between the two lower brackets 13 and is used to splice the sheaths at the end connection of the two cable sections;

[0043] The sheath splicing mechanism includes a metal sleeve 5, a metal sleeve 5 is arranged between the lower support seat 13, mounting ring seats 14 are arranged on both sides of the middle of the inner wall of the metal sleeve 5, sealing ring seats 18 are arranged in the inner middle of the mounting ring seat 14, and a repair cavity 15 is formed between the sealing ring seats 18, an injection tube 12 is arranged in the middle of one side of the outer wall of the metal sleeve 5, and the interior of the injection tube 12 is connected with the interior of the repair cavity 15, and a rotating cover 21 is arranged on the top of the injection tube 12.

[0044] When the sheath splicing mechanism is started, after the separation repair mechanism repairs the connection between the two sections of metal wires, the staff will move the metal sleeve 5 inserted into the cable to the position where the two sections of the cable are connected. After the metal sleeve 5 moves to its repair position, the sealing ring seat 18 on the installation ring seat 14 will seal both sides of the repair position. Then the staff will open the rotating cover 21 on the injection tube 12, and inject the melted insulation repair material into the repair cavity 15 in the metal sleeve 5 through the rotating cover 21. The insulation repair material flowing in the repair cavity 15 repairs the outer insulation skin part of the connection position of the two sections of the cable, thereby completing the splicing operation of the insulation sheath after the two sections of the cable.

[0045] The end support mechanism is arranged on the lower support seat 13 and is used to support and prevent deformation of both sides of the cable after the sheath splicing mechanism splices the cable;

[0046] The end support mechanism includes an upper lifting seat 1, and the upper lifting seat 1 is arranged on the top of the lower supporting seat 13. An annular cavity 3 is opened in the middle of the side adjacent to the upper lifting seat 1 and the lower supporting seat 13, and a rubber ring seat 2 is arranged on the inner wall of the annular cavity 3. Vertical adjustment rods 7 are arranged on both sides of the middle of the top of the lower supporting seat 13, and the top of the vertical adjustment rod 7 passes through the upper lifting seat 1 and extends outward, and a locking nut 8 is threadedly connected on the vertical adjustment rod 7.

[0048] When the end support mechanism is started, the staff first installs the upper lifting seat 1 on the lower supporting seat 13, and then squeezes the upper lifting seat 1 to move toward the lower supporting seat 13 by rotating the locking nut 8 on the vertical adjustment rod 7. While the upper lifting seat 1 approaches the lower supporting seat 13, it squeezes and fixes the outer wall of the cable through the rubber ring seat 2 in the annular cavity 3. The above operation is repeated to fix the other section of the cable in the same way. Then the staff connects the upper lifting seat 1 and the lower supporting seat 13 at both ends of the cable through the horizontal adjustment rod 10, and fixes them through the adjusting nuts 6 on both ends of the horizontal adjustment rod 10, so as to ensure that the position of the outer insulation layer repaired by the sheath splicing mechanism at the connection between the two sections of the cable is in a horizontal state, and at the same time, it can also prevent its repair position from being affected by external forces, so as to complete the end support processing of the two sections of the cable.

[0051] When the repair shaping mechanism is started, when the sheath splicing mechanism repairs the outer wall insulation layer of the two sections of the cable, the high temperature of the high-temperature repair material in the repair cavity 15 is discharged to the external environment through the metal sleeve 5, thereby accelerating its shaping in the first step, and then the material in the repair cavity 15 conducts the external temperature and the heat is absorbed by the aluminum alloy fins 9 outside the metal sleeve 5, and then conducted again to the arc-shaped metal plate 4 on the same side, thereby expanding its heat dissipation area, and because the acceleration cavity formed between adjacent aluminum alloy fins 9 can accelerate the speed of air passing through the external environment, the heat generated by the repair material in the repair cavity 15 is taken away to the greatest extent by the accelerated flow of air, thereby promoting the shaping of the cable repair position.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
