Description

Technical Field

[0001] This invention relates to the field of insulating sleeve technology, specifically an insulating sleeve and a live-line installation mechanism. Background Technology

[0002] In the field of power transmission, the stability and reliability of overhead power lines in distribution networks are crucial as the key carriers for transmitting electricity at the end. With increasing years of operation, the insulation layers of conductors, switches, disconnectors, and transformer terminals in these overhead lines are prone to aging and sheath cracking. This leads to the detachment of insulation sheaths at the connections of various equipment terminals and lead wire (bow wire) clamps, and cracking of the insulation layer at the top of insulators on straight poles, exposing the cable core. These become weak points in the insulation protection of overhead lines. In recent years, with continuous environmental improvements and changes, failures caused by foreign objects or small animals at these weak points have increased significantly. Taking Urumqi as an example, such failures account for more than 20%, with a huge impact. Protecting these weak points has become a critical issue in reality.

[0003] Currently, the most commonly used protective sleeves on the market are soft silicone sleeves, which offer reliable protection. However, they require installation without power. If installed while the power is on, manual installation using a live trolley or platform is necessary, along with safety measures such as insulation wrapping. Live installation is inefficient and extremely costly. Transparent polycarbonate insulating sleeves on the market can be installed with simple insulating rods. However, the insulating rods have a simple structure and cannot achieve multi-dimensional adjustment, making installation difficult. Furthermore, the sleeve structure consists of two halves, with a spring at the top in the middle to hold the sleeve together. This does not allow for multi-point stress closure, resulting in concentrated stress points that become weak points for later aging and damage.

[0004] Chinese patent document CN110415950A discloses a transformer insulation sleeve, which includes a first sleeve shell and a second sleeve shell. The sides of the first and second sleeve shells are provided with fixing strips, and fixing plastic nails are embedded in the sides of the fixing strips. The sides of the first and second sleeve shells are provided with bending strips. The bottom surfaces of the first and second sleeve shells are provided with wire clamp shells, and the bottom surfaces of the wire clamp shells are provided with fixing shells. The top surfaces of the first and second sleeve shells are provided with outlet shells, and the top surfaces of the outlet shells are provided with outlet reinforcing rings. Compared with existing equipment wire clamps, this technical solution neglects insulation protection, is difficult to install, and is inconvenient for live installation. Compared with conventional silicone sleeves, it has no significant technical advantages or changes. Furthermore, it is difficult to replace, and can almost only be removed after a power outage.

[0005] Chinese patent document CN111653982A discloses a live-line installation tool for silicone rubber insulating sleeves and its usage method. The installation tool includes an insulating operating rod, a control box mounted on the insulating operating rod, and an installation head mounted on the top of the insulating operating rod. The installation head includes a U-shaped main mounting plate, a left clamping plate, a right clamping plate, an electric push rod, and insulating sleeve hole nail mounting parts. The left and right clamping plates are positioned opposite each other on both sides of the U-shaped main mounting plate and are hinged to the U-shaped main mounting plate. One end of the electric push rod is hinged to the left clamping plate, and the other end is hinged to the right clamping plate. The top of both the left and right clamping plates is provided with the insulating sleeve hole nail mounting parts. The control box contains a control circuit board and a first power module. The control circuit board is electrically connected to the electric push rod for controlling the movement of the electric push rod. The bottom of the insulating operating rod is provided with a control button electrically connected to the control circuit board. Compared with existing technologies, this technical solution does not consider multi-angle conditions on site, has poor adaptability to multi-angle installation, poor visual installation control and operability, and the commonly used silicone is soft and not easy to control the overall assembly process at a single point. In actual use, the installation efficiency is low, the installation quality and reliability are difficult to control, and the design is only suitable for wires and not for the installation of complex structures such as equipment terminals and clamps.

[0006] Chinese patent document CN115890574A discloses a portable, live-line quick-installation tool for insulating sheaths, comprising: a holding mechanism including a fixed rod, an extension rod located at the bottom of the fixed rod, a snap-fit ​​component located on the outer side of the top of the extension rod, an interface located on the top surface of the extension rod, a plug-in connector located at the bottom of the extension rod, and a snap-fit ​​hole located on the outer side of the lower part of the extension rod; and an assembly mechanism including an outer frame located at the top of the fixed rod, a clamping component installed inside the outer frame, a support component located at the top of the outer frame, a snap-fit ​​rod located on the outer side of the support component, and a transmission component located in the middle section inside the outer frame. This technical solution is also only suitable for conductors and cannot meet the installation requirements of complex structures such as equipment terminals and clamps.

[0007] Chinese patent document CN119601374A discloses a live-installation transformer terminal insulation sleeve installation device. This technical solution only applies to transformer terminals, and its feasibility for other equipment terminals and connection points cannot be guaranteed. The matching sleeve has poor sealing performance, and the fitting structure of this technical solution cannot meet the installation requirements of weak points in complex structures such as other equipment terminals and clamps, resulting in poor practicality and applicability. The matching insulation installation operation structure cannot meet the multi-dimensional installation requirements, and replacement is difficult, almost only requiring removal after a power outage.

[0008] Currently, there is considerable research on insulation technology for conductors, but less research on the protection of critical fixed connections such as equipment terminals and clamps. In particular, there is very little research on the sheathing of insulated rods for live-lined equipment terminals and clamps, and on live-lined equipment itself. Summary of the Invention

[0019] This invention features a reasonable and compact structure. The operating head of an insulating rod is inserted into the first disassembly ring. The insulating rod is used to move the insulating sleeve above the equipment pile or clamp to be installed. The operating head of the other insulating rod is then inserted into the second disassembly ring. Pushing one of the insulating rods upwards causes the lower rear side of the first housing and the lower front side of the second housing to move away from each other, creating an opening in the lower parts of both housings. Simultaneously moving both insulating rods downwards allows the first and second housings to be placed over the equipment pile or clamp. After removing the two insulating rods, the polarities of the two adjacent surfaces of the first and second magnets on the first and second housings are opposite, causing them to attract each other and bring the first and second housings together, making contact between the rear side of the first housing and the front side of the second housing. This allows the first and second housings to be installed outside the equipment pile or clamp. Alternatively, the insulating sleeve can be carried to the target location by a worker for direct installation.

[0020] The insulating sleeve of this application can achieve rapid closing and installation while energized. The insulating sleeve of this application has a two-half structure. Its installation and closure are achieved by the first and second magnets on both sides, in conjunction with the insulating rod and the operating head, to achieve rapid opening and closing of the insulating sleeve. It can be replaced without power interruption, and the replacement is simple. The insulating sleeve of this application works by magnetic attraction and can be removed by inserting the insulating rod into the removal hole and prying it off, which is convenient to operate.

Detailed Implementation

[0034] The present invention is not limited to the following embodiments, and the specific implementation can be determined according to the technical solution of the present invention and the actual situation.

[0035] In this invention, for ease of description, the description of the relative positions of the components is based on the appendix to the specification. Figure 1 The layout is described using a diagrammatic method, such as the positional relationships of front, back, top, bottom, left, and right, which are based on the instructions attached. Figure 1 The orientation of the layout is determined by the direction of the map.

[0036] The present invention will be further described below with reference to embodiments and accompanying drawings: Example 1: As shown in the attached document Figure 1 , 2As shown in Figures 3 and 4, the insulating sheath includes a first housing 1, a second housing 2, and a hinge assembly. The upper middle part of the first housing 1 and the upper middle part of the second housing 2 are hinged together by the hinge assembly. The outer rear part of the first housing 1, corresponding to the positions on both sides of the hinge assembly, has several first mounting slots with outward openings distributed circumferentially. Each first mounting slot contains a first magnet 3. The outer front part of the second housing 2, corresponding to each first mounting slot, has a second mounting slot with outward openings. Each second mounting slot contains a second magnet 4. The polarities of the two faces of the second magnet 4 and the first magnet 3 that are close to each other are opposite. A first disassembly ring 5 is fixedly installed on the front left side of the first housing 1, and a second disassembly ring 6 is fixedly installed on the rear side of the second housing 2, corresponding to the position of the first disassembly ring 5.

[0037] Depending on the requirements, in order to ensure insulation performance, oxidation resistance and protection performance, the first shell 1 and the second shell 2 can be made of hardened high-temperature vulcanized silicone rubber. After the rear side of the first shell 1 and the front side of the second shell 2 come into contact, they can form a protective cavity that matches the fixed connection points such as equipment piles and clamps in the existing power grid. After the rear side of the first shell 1 and the front side of the second shell 2 come into contact, they can cover the outside of the fixed connection points such as equipment piles and clamps. The first magnet 3 and the second magnet 4 can both be cylindrical or strip-shaped. The first magnet 3 and the second magnet 4 are both existing known magnets, such as hard ferrite magnets.

[0038] During use, the operating head of the insulating rod 20 can be inserted into the first disassembly ring 5. The insulating sleeve can be moved to the top of the equipment pile or wire clamp to be installed using the insulating rod 20. The operating head of the other insulating rod 20 can be inserted into the second disassembly ring 6. After pushing one of the insulating rods 20 upward, the lower rear side of the first housing 1 and the lower front side of the second housing 2 will move away from each other, thus forming an opening at the bottom of the first housing 1 and the second housing 2. Then, both insulating rods 20 can be moved downward at the same time, so that the first housing 1 and the second housing 2 can be covered on the outside of the equipment pile or wire clamp. After removing the two insulating rods 20, the polarities of the two adjacent surfaces of the first magnet and the second magnet 4 on the first housing 1 and the second housing 2 are opposite. Thus, the first magnet 3 and the second magnet 4 attract each other, so that the first housing 1 and the second housing 2 can be brought together, so that the rear side of the first housing 1 and the front side of the second housing 2 can be in contact with each other. The first housing 1 and the second housing 2 can then be installed on the outside of the equipment pile or wire clamp. Alternatively, the operator can carry the insulating sleeve to the target position and install it directly.

[0039] The insulating sleeve of this application can achieve rapid closing and installation while energized. The insulating sleeve of this application has a two-half structure. Its installation and closure are achieved by the first magnet 3 and the second magnet 4 on both sides, together with the insulating rod 20 and the operating head, so as to achieve rapid opening and closing of the insulating sleeve without power interruption. The replacement is simple. The insulating sleeve of this application works by magnetic attraction and can be removed by inserting the insulating rod 20 into the removal hole and prying it off. The operation is convenient.

[0040] The above-mentioned insulating sheath can be further optimized and / or improved according to actual needs: Example 2: As an optimization of the above examples, as shown in the appendix. Figure 1 , 3 As shown, the first housing 1 has a third mounting groove with an opening facing forward on the front side of the middle part. A third magnet 7 is installed in the third mounting groove. The rear side of the third magnet 7 has the same polarity as the front side of the first magnet 3. The second housing 2 has a fourth mounting groove with an opening facing backward on the rear side of the middle part corresponding to the position of the third mounting groove. A fourth magnet 8 is installed in the fourth mounting groove. The front side of the fourth magnet 8 has the same polarity as the rear side of the second magnet 4.

[0041] Depending on the requirements, both the third magnet 7 and the fourth magnet 8 can be cylindrical. Both the third magnet 7 and the fourth magnet 8 are existing known magnets, such as soft magnetic ferrite. During use, by setting the third magnet 7 and the fourth magnet 8, the rear side of the third magnet 7 and the front side of the fourth magnet 8 can attract the first magnet 3 and the second magnet 4 to move closer together. This ensures that the rear side of the first housing 1 and the front side of the second housing 2 are in close contact, thereby ensuring the protective and insulating effect of the insulating sleeve on the equipment terminals and clamps.

[0042] Example 3: As an optimization of the above examples, as shown in the appendix. Figure 1 , 2As shown in Figures 3 and 4, the hinge assembly includes a front connecting plate 9, a rear connecting plate 10, a hinge shaft 11, a top seat 12, and a fifth magnet 13. The rear connecting plate 10 is fixedly installed on the upper front part of the second housing 2. The rear connecting plate 10 has several through rear disassembly holes 14 spaced apart on the left and right sides of its front side. The rear connecting plate 10 has two rear fixing sleeves 16 spaced apart on its upper side. The front connecting plate 9 is fixedly installed on the upper side of the first housing 1 corresponding to the position of the rear connecting plate 10. The front connecting plate 9 has a through front disassembly hole 15 on its front side corresponding to each rear disassembly hole 14. The front connecting plate 9 is fixedly fixed on its upper side at intervals between the two rear fixing sleeves 16. Two front fixing sleeves 17 are installed. A hinge shaft 11 is provided in the middle of the rear fixing sleeve 16 and fitted inside the front fixing sleeve 17. A top seat 12 is fitted on the outer side of the middle of the hinge shaft 11 corresponding to the position between the two front fixing sleeves 17. A fixing groove with an upward opening is provided on the upper side of the top seat 12. A fifth magnet 13 is installed in the fixing groove. A rear skirt 19 is fixed along the circumferential direction on the surface of the second housing 2 corresponding to the left and right positions of the rear connecting plate 10. A second mounting groove is spaced on the surface of the rear skirt 19. A front skirt 18 is fixed along the circumferential direction on the surface of the first housing 1 corresponding to the left and right positions of the front connecting plate 9. A first mounting groove is spaced on the surface of the front skirt 18.

[0043] During use, the front skirt 18 and rear skirt 19 facilitate the installation of the first magnet 3 and the second magnet 4, enabling the first housing 1 and the second housing 2 to close quickly. They also increase the contact area between the rear side of the first housing 1 and the front side of the second housing 2, resulting in uniform force distribution between them and improving the sealing effect. The top seat 12 and the fifth magnet 13 can be attached together with tools during disassembly and assembly, thus positioning the top seat 12 and facilitating the opening and closing of the first housing 1 and the second housing 2.

[0044] Example 4: As attached Figures 5 to 11 As shown, the live mounting mechanism is used for disassembling and assembling insulating sleeves. The live mounting mechanism includes an insulating rod 20, a mounting sleeve 21, a support arm 22, a first opposing damping joint 60, a second opposing damping joint, a front claw arm 23, a rear claw arm 24, and a drive mechanism. The mounting sleeve 21 is detachably fixedly mounted on the upper part of the insulating rod 20. The first opposing damping joint 60 is hinged between the upper part of the mounting sleeve 21 and the right end of the support arm 22. The second opposing damping joint is hinged between the left end of the support arm 22 and the upper end of the disassembly and assembly base 63. The front claw arm 23 and the rear claw arm 24 are hingedly mounted on the lower part of the disassembly and assembly base 63. A drive mechanism is installed on the upper part of the disassembly and assembly base 63 to allow the lower rear side of the front claw arm 23 and the lower front side of the rear claw arm 24 to approach or move away from each other. The lower rear side of the front claw arm 23 is provided with a front adsorption component that can adsorb the front side of the first housing 1, and the lower front side of the rear claw arm 24 is provided with a rear adsorption component that can adsorb the rear side of the second housing 2.

[0045] Depending on the requirements, the insulating rod 20 can be made of materials with excellent mechanical and insulation properties such as nylon, ABS, and PEEK to improve the safety performance during live-line work. In order to facilitate the assembly and disassembly of the mounting sleeve 21 and the insulating rod 20, the mounting sleeve 21 is a two-part split shell structure connected together by bolts.

[0046] During use, by setting the first opposing damping joint 60 and the second opposing damping joint, the angle between the insulating rod 20, the support arm 22 and the disassembly and assembly base 63 can be easily adjusted. The insulating sheath can be disassembled and assembled with the equipment pile and the wire clamp from multiple positions, reducing the difficulty of disassembly and assembly. The first opposing damping joint 60 and the second opposing damping joint have a damping posture maintenance function. During on-site operations, the joint can be adjusted at multiple angles according to the position of the equipment pile, the wire clamp and the operator, which greatly improves the installation efficiency.

[0047] When disassembling the insulating sleeve, adjust the angles of the insulating rod 20 and the disassembly / removal seat 63 according to the target position. Then, the operator raises the insulating rod 20 and places the disassembly / removal seat 63 on the top seat 12. The fifth magnet 13 is attracted to the lower part of the disassembly / removal seat 63, thus connecting the disassembly / removal seat 63 to the top seat 12 and the fifth magnet 13. Then, the drive mechanism moves, causing the lower rear side of the front claw arm 23 to approach the front side of the first housing 1. Then, the front adsorption component is attracted to the third magnet 7, thus connecting the lower rear side of the front claw arm 23 to the front side of the first housing 1. At the same time, the rear... The lower front side of the claw arm 24 is close to the rear side of the second housing 2, and then the rear adsorption assembly is adsorbed together with the fourth magnet 8. In this way, the lower front side of the rear claw arm 24 can be connected to the rear side of the second housing 2. After the drive mechanism is working, the lower rear side of the front claw arm 23 and the front side of the rear claw arm 24 move away from each other. When the lower rear side of the front claw arm 23 and the front side of the rear claw arm 24 move away from each other, the lower parts of the first housing 1 and the second housing 2 can be opened. Then, the insulating rod 20 is pushed upward. The insulating rod 20 can drive the disassembly and assembly seat 63 and the insulating sleeve to separate from the equipment terminal and wire clamp, making disassembly convenient.

[0048] Example 5: As an optimization of the above examples, as shown in the appendix. Figures 5 to 8As shown in Figures 10 and 11, the drive mechanism includes a geared motor 25, a lifting plate 26, a lead screw 27, a retaining cover 28, and a control unit. The geared motor 25 and the control unit are fixedly installed on the inner side of the upper part of the disassembly and assembly base 63. The control unit is electrically connected to the geared motor 25. A base plate 29 is fixedly installed on the inner side of the lower part of the disassembly and assembly base 63. The lifting plate 26 is located above the base plate 29. The lifting plate 26 has a threaded through hole in the center. The lead screw 27 is screwed into the threaded through hole. The upper end of the lead screw 27 is driven and installed together with the lower end of the output shaft of the geared motor 25. A front connecting rod is hinged between the front part of the lifting plate 26 and the upper side of the front part of the front claw arm 23. 30. A rear connecting rod 62 is hinged between the rear part of the lifting plate 26 and the upper rear part of the rear claw arm 24. Two first hinge rings 31 are fixedly installed on the upper rear side of the front claw arm 23 at intervals. Two second hinge rings 32 are fixedly installed on the upper front side of the rear claw arm 24 at intervals between the two first hinge rings 31. Each second hinge ring 32 is provided with a hinge rod 61 whose end passes through the corresponding first hinge ring 31 and is installed together with the lower part of the mounting base 63. A clip cover 28 that can be fitted onto the outside of the top seat 12 is fixedly installed on the lower side of the base plate 29 at the position between the two second hinge rings 32.

[0049] The disassembly / assembly base 63 can be H-shaped. During use, when the output shaft of the geared motor 25 rotates clockwise, it drives the lead screw 27 to rotate clockwise. When the lead screw 27 rotates clockwise, it causes the lifting plate 26 to move upward. After the lifting plate 26 moves upward, it can pull the front claw arm 23 and the rear claw arm 24 upward through the front connecting rod 30 and the rear connecting rod 62, thereby opening the first housing 1 and the second housing 2. Similarly, when the output shaft of the geared motor 25 rotates counterclockwise, it drives the lead screw 27 to rotate counterclockwise. When the lead screw 27 rotates counterclockwise, it causes the lifting plate 26 to move downward. After the lifting plate 26 moves downward, it can release the front claw arm 23 and the rear claw arm 24 downward through the front connecting rod 30 and the rear connecting rod 62, thereby closing the first housing 1 and the second housing 2, which facilitates the disassembly and assembly of the insulating sleeve.

[0053] Depending on the requirements, the lower rear side of the front claw arm 23 and the front side of the front finger 36, and the lower front side of the rear claw arm 23 and the rear end of the rear finger 39 can be hinged together using existing known damping hinges. During use, when the cover 28 is fitted onto the outside of the top seat 12, the first electromagnet 37 and the second electromagnet 40 are energized via the remote control module. The energized electromagnets 37 and 40 generate magnetic fields, allowing them to attract the third magnet 7 and the fourth magnet 8 respectively. Then, the remote control module causes the reduction motor 25 to rotate forward or backward, facilitating the connection between the front finger 36 and the first housing 1, and the rear finger 39 and the second housing 2. The magnetic fields generated by the energized electromagnets 37 and 40 prevent them from attracting other surfaces of the housing during assembly and disassembly, making the assembly and disassembly of the insulating sleeve more accurate.

[0054] Example 8: As an optimization of the above examples, as shown in the appendix Figure 5 , 7As shown in Figures 8, 10 to 12, the upper side of the cover 28 is provided with a guide groove 42 that runs vertically through it.
