Description

Technical Field

[0001] This utility model relates to the field of power system operation and maintenance equipment technology, and in particular to power system operation and maintenance tools. Background Technology

[0002] The operation and maintenance of the service lines at the end of the power system (especially in old urban communities and rural areas) still generally rely on manual operation and maintenance. The core process is: after cutting the aging or faulty wires with manual wire cutters, the operators manually wrap ordinary PVC insulating tape to cover the wires.

[0003] However, existing manual maintenance methods still have many shortcomings. On the one hand, it is usually time-consuming for a single person to complete wire cutting and insulation wrapping, and the tape tension and overlap need to be repeatedly adjusted during the tape wrapping process, making the operation cumbersome and the work inefficient. On the other hand, when manually wrapping PVC insulating tape, problems such as air gaps, wrinkles, and loosening are prone to occur, resulting in poor insulation reliability. Moreover, workers usually need to be in close contact with exposed conductors during the PVC insulating tape wrapping process, which poses a high safety risk, especially in live-line working scenarios.

[0004] Therefore, there is an urgent need for a power operation and maintenance tool to solve the above problems. Utility Model Content

[0056] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0060] This embodiment provides a power system operation and maintenance tool, such as Figure 1 and Figure 2As shown, the power system maintenance tool includes an insulating rod 100, a base assembly 200, and a shearing clamping device 300. The base assembly 200 is detachably mounted on one end of the insulating rod 100, and the shearing clamping device 300 is mounted on the base assembly 200. The power system maintenance tool also includes a spraying device 400. The base assembly 200 has a liquid storage chamber 221 configured to contain insulating liquid. The spraying device 400 is rotatably mounted on the base assembly 200 and communicates with the liquid storage chamber 221. The spraying device 400 is configured to spray the insulating liquid in the liquid storage chamber 221 onto the cut conductor. By integrating the shearing clamping device 300 and the spraying device 400, and by setting up the liquid storage chamber 221 to contain the insulating liquid, operators can immediately spray the cut surface of the conductor with insulating liquid without switching tools after cutting the conductor, eliminating the tedious steps of repeatedly adjusting tension, overlapping wrapping, and tearing the tape in the traditional manual wrapping of PVC insulating tape. The operation time has been reduced from 1-3 minutes in the traditional way to 10-20 seconds, which is especially suitable for large-scale and high-frequency operation and maintenance scenarios such as old residential areas and rural power lines, and significantly improves operation efficiency.

[0061] Furthermore, by integrating the spraying device 400 into one end of the insulating rod 100, workers can complete the entire process of wire cutting and insulation spraying from a safe distance using the insulating rod 100, without close contact with exposed conductors, thus avoiding the risk of hands coming into contact with live parts when manually wrapping tape. Simultaneously, the spraying process can complete insulation coverage in a very short time, significantly shortening the dangerous time window for exposed conductors after wire cutting. This design reduces reliance on personal protective equipment such as insulating gloves, making live-line work safer and more controllable.

[0062] Optionally, the spraying device 400 includes a telescopic tube assembly 410 and a spraying power source. One end of the telescopic tube assembly 410 is rotatably connected to the base assembly 200 and can rotate around a first axis perpendicular to the axis of the insulating rod 100. The other end of the telescopic tube assembly 410 is provided with a liquid outlet 4122, which is connected to the liquid storage chamber 221 through the telescopic tube assembly 410. The telescopic tube assembly 410 can extend or shorten along its own axial direction. The spraying power source is configured to drive the insulating liquid in the liquid storage chamber 221 to be sprayed out through the liquid outlet 4122 onto the cut wire. With this configuration, the spraying angle and spraying distance can be adjusted according to the position of the wire and the working space, improving the adaptability of the spraying device 400 to wires with different installation heights and orientations, and enhancing the flexibility and convenience of operation and maintenance.

[0063] like Figure 3As shown, the telescopic tube assembly 410 includes a first tube 411, a second tube 412, a first driving member 413, and a liquid guide tube 415. One end of the first tube 411 is rotatably connected to the base assembly 200, and the second tube 412 is slidably engaged with the first tube 411. The output end of the first driving member 413 is provided with a first gear 414. One of the inner wall of the first tube 411 and the outer wall of the second tube 412 is provided with a first rack portion 4121, and the other is provided with the first driving member 413. The first gear 414 meshes with the first rack portion 4121. One end of the liquid guide tube 415 is connected to the liquid storage chamber 221, and the other end passes through the first tube 411 and the second tube 412 and extends to the liquid outlet 4122. The first driving member 413 can drive the second tube 412 to extend or retract from the first tube 411, thereby adjusting the distance between the liquid outlet 4122 and the guide wire, and improving the adaptability of the spraying device 400 to different working conditions.

[0064] Optionally, the first driving component 413 is a first motor, and the output shaft of the first motor is coaxially fixed with the first gear 414, thereby providing a stable and reliable power input to ensure that the second tube 412 extends or retracts along the first tube 411.

[0065] Optionally, the spraying power source can be a first drive pump, which is disposed within the liquid storage chamber 221. The inlet of the first drive pump is connected to the liquid storage chamber 221, and the outlet of the first drive pump is connected to the liquid guide pipe 415. Pressurization by the drive pump ensures that the insulating liquid is sprayed onto the wire. In other embodiments, the spraying power source can be a pressurizing component, which is connected to the liquid storage chamber 221. The pressurizing component provides pressure to the liquid storage chamber 221, making the pressure inside the liquid storage chamber 221 greater than the external pressure, so that the insulating liquid is sprayed out through the liquid guide pipe 415.

[0066] Optionally, the insulating liquid is an acrylic copolymer emulsion, which has the characteristics of rapid curing, resistance to water vapor leakage, rust prevention, and high dielectric strength, and can improve the insulation protection strength and work efficiency.

[0067] like Figure 1 , Figure 4 and Figure 5As shown, the insulating rod 100 includes a plurality of detachably connected rod bodies 110. At least one rod body 110 is provided with a counterweight assembly 500. The counterweight assembly 500 includes a counterweight block 510 and an operating member 520. The rod body 110 is provided with a receiving cavity extending along the axial direction of the rod body 110. The counterweight block 510 is movably disposed in the receiving cavity along the axial direction of the rod body 110. The rod body 110 is provided with a guide hole and a second rack portion 111 corresponding to the receiving cavity. The operating member 520 passes through the guide hole and is connected to the counterweight block 510. The operating member 520 is provided with a locking portion 521 on the side facing the second rack portion 111. The locking portion 521 can move or stop along the second rack portion 111. With this configuration, the counterweight 510 can be moved axially along the insulating rod 100 by the operating component 520, thereby adjusting the position of the counterweight 510 on the insulating rod 100. This adjusts the overall center of gravity of the power system maintenance tool, reduces the torque on the operator's hands, improves operational stability, and reduces the labor intensity of long-term maintenance work. At the same time, the counterweight 510 can be locked in a preset position by the locking part 521 cooperating with the second rack part 111, preventing the counterweight 510 from moving during operation and improving the stability of counterweight adjustment and safety of use.

[0068] Optionally, the locking part 521 can be an elastic locking tooth. By applying force to the operating member 520 by the operator, the lever arm of the elastic locking tooth can be slightly deformed, thereby allowing the elastic locking tooth to engage at different positions on the second rack part 111, achieving center of gravity adjustment. In other embodiments, the locking part 521 can be any structure in the prior art that realizes locking and unlocking functions, and the structure of the locking part 521 will not be described in detail.

[0069] Optionally, the insulating rod 100 is composed of multiple detachable rods 110 connected together, allowing for flexible adjustment of the length of the insulating rod 100 according to the working height, thus improving operational flexibility. In this embodiment, each rod 110 is made of carbon fiber, which has extremely high specific strength (tensile strength) and specific modulus, ensuring the strength of the insulating rod 100 and making it lightweight, reducing the burden on the operator's hands.

[0070] like Figure 5 As shown, the surface of the insulating rod 100 is densely coated with high-performance epoxy resin to form a robust insulating protective layer 112, which effectively improves the electrical insulation performance and environmental resistance of the rod 110.

[0071] Preferably, the counterweight assembly 500 is disposed on the bottommost rod 110 of the insulating rod 100 to increase the distance between the counterweight assembly 500 and the shearing clamping device 300, thereby improving the ability of the counterweight assembly 500 to adjust the overall center of gravity of the power system maintenance tool and reducing the torque borne by the operator's hands.

[0072] like Figure 6 and Figure 7 As shown, the power system operation and maintenance tool also includes a connection assembly 600. The connection assembly 600 includes a connecting sleeve 610, a first top block 620, a second top block 630, and a fastener 640. The connecting sleeve 610 includes an inner tube portion 611, an outer tube portion 612, and a limiting groove 613. The inner tube portion 611 is inserted into the insulating rod 100, and at least a portion of the insulating rod 100 is sandwiched between the inner tube portion 611 and the outer tube portion 612. The base assembly 200 is detachably connected to the connecting sleeve 610. The first top block 620 is disposed at the limiting groove 613, and the second top block 630 is disposed inside the connecting sleeve 610. Fastener 640 passes through the first top block 620 and the second top block 630, and is threadedly connected to the second top block 630. Fastener 640 is configured to drive the second top block 630 to move closer to the first top block 620, causing the second top block 630 to drive the inner tube portion 611 to expand radially, thereby fixing the connecting sleeve 610 to the top of the insulating rod 100. This interference fit connection effectively avoids structural damage to the rod body 110 caused by direct tapping. While ensuring connection strength and reliability, it retains the advantages of the extreme lightweight of carbon fiber material and achieves convenient installation. In this embodiment, the first top block 620 has a first through hole, the second top block 630 has a threaded hole, and the fastener 640 is a bolt. The bolt passes through the first through hole and the threaded hole in sequence and is threadedly connected to the second top block 630.

[0073] like Figure 6 As shown, the outer wall of the inner tube 611 is provided with anti-slip pattern 6112. When the fastener 640 is screwed in, it drives the second top block 630 at the bottom to move upward along the axial direction, generating a radial expansion force. This forces the irregular anti-slip pattern 6112 on the outer wall of the inner tube 611 to be tightly embedded in the inner wall of the carbon fiber rod 110, achieving mechanical locking and improving the firmness and reliability of the connection between the connecting component 600 and the insulating rod 100.

[0074] Optionally, the diameter of the second top block 630 gradually increases in the direction away from the first top block 620, so that the second top block 630 can exert a radial pushing effect on the inner tube 611 when it moves towards the first top block 620, thereby causing the inner tube 611 to make interference fit with the inner wall of the insulating rod 100.

[0075] Optionally, the inner tube portion 611 has at least one notch 6111 along its axial direction, enabling it to have radial elastic deformation capability. This allows it to expand radially under the support of the second top block 630, ensuring a tight fit between the inner tube portion 611 and the inner wall of the insulating rod 100. This achieves a reliable clamping connection between the connecting sleeve 610 and the insulating rod 100, improving the installation stability of the base assembly 200 and reducing the risk of loosening and detachment during operation. In this embodiment, the inner tube portion 611 has multiple notches 6111 along its circumference, allowing for more uniform radial expansion under the support of the second top block 630, thus improving the firmness of the interference fit.

[0076] Optionally, the limiting groove 613 is a conical groove. Along the direction in which the first top block 620 is assembled to the limiting groove 613, the diameter of the first top block 620 gradually decreases, so that during the locking process of the fastener 640, the first top block 620 also provides radial tension force to the inner tube 611.

[0077] like Figure 8 As shown, the base assembly 200 includes a first base 210, a second base 220, and a second drive component. The first base 210 is detachably connected to the connecting sleeve 610, and the second base 220 is rotatably connected to the first base 210. A shearing clamping device 300 and a spraying device 400 are both mounted on the second base 220. The output end of the second drive component is drively connected to the second base 220. The second drive component is configured to drive the second base 220 to rotate relative to the first base 210, which can synchronously adjust the working angle of the shearing clamping device 300 and the spraying device 400 mounted on the second base 220. This allows for flexible adjustment of the shearing and spraying directions according to the conductor position and working space requirements, improving the adaptability of power system maintenance tools to different working conditions. In this embodiment, the second drive component is a second motor, which is drively connected to the second base 220 to drive the second base 220 to rotate.

[0078] like Figure 9As shown, the power system operation and maintenance tool also includes an image acquisition component 700, a display screen 120, and a control component. The image acquisition component 700 is mounted on the base component 200, while the display screen 120 and control component are both mounted on the insulating rod 100. The shearing clamping device 300, the spraying device 400, the image acquisition component 700, and the display screen 120 are all communicatively connected to the control component. The display screen 120 is configured to display images of the working area acquired by the image acquisition component 700. With this configuration, the image acquisition component 700 can acquire images of the working area in real time and transmit them to the display screen 120 for display via the control component. This allows the operator to observe the working area of ​​the shearing clamping device 300 and the spraying device 400 in real time while working remotely from the insulating rod 100, thereby improving the accuracy of identifying the target conductor position and the precision of shearing and spraying operations. Simultaneously, observation and operation control can be completed without the operator approaching the energized area, which helps improve the safety of operation and maintenance, reduces the difficulty of operation in high-altitude, obstructed, or confined spaces, and improves operation and maintenance efficiency.

[0079] In one embodiment, the spraying device 400 and the shearing clamping device 300 are interlocked through a control component. During operation, the image acquisition component 700 acquires image information of the working area and sends the acquired image information to the control component. The control component identifies the state of the wire based on the image information. When the control component identifies that the target wire has been cut by the shearing clamping device 300, the control component allows the spraying device 400 to be started, thereby avoiding premature spraying of insulating liquid by the spraying device 400 due to misoperation or accidental triggering, and reducing waste of insulating liquid.

[0080] like Figure 9 As shown, the image acquisition component 700 includes a first support base 710, a camera 720, and a third driving component. The first support base 710 is mounted on the base assembly 200. The camera 720 is rotatably mounted on the first support base 710 and can rotate around a second axis perpendicular to the axis of the insulating rod 100. The output end of the third driving component is connected to the camera 720 for transmission. The third driving component is configured to drive the camera 720 to rotate around the second axis. With this configuration, by driving the camera 720 to rotate around the second axis through the third driving component, the shooting angle of the camera 720 can be adjusted according to the position of the target wire and the working environment, thereby expanding the observation range of the image acquisition component 700 over the working area and improving the visualization capability of the target wire at different heights, in different orientations, and under obstructed environments. This is beneficial for improving the accuracy of cutting, clamping, and spraying operations.

[0081] Optionally, the third driving component is a third motor. The output shaft of the third motor is provided with a second gear 730, and the housing 800 of the camera 720 is provided with a third gear 740. The second gear 730 and the third gear 740 mesh, and the angle of the camera 720 is adjusted under the drive of the third motor.

[0082] Optionally, the control component can be a single microcontroller or a combination of multiple microcontrollers. The control program runs in the microcontroller to realize the functions of cutting, clamping, spraying, and image acquisition and display. The connection circuits between the cutting and clamping device, the spraying device 400, and the image acquisition component 700 and the control component are prior art in this field and will not be described in detail.

[0083] Optionally, a fourth driving component is provided on the second base 220. The output shaft of the fourth driving component is connected to the first tube 411 for transmission. The fourth driving component can drive the telescopic tube assembly 410 to swing around the first axis, thereby adjusting the spray angle of the insulating liquid and improving the uniformity of spraying. In this embodiment, the fourth driving component is a fourth motor. A fifth gear is provided at the bottom of the first tube 411. The output shaft of the fourth motor is provided with a fourth gear. The fourth gear meshes with the fifth gear. Under the drive of the fourth motor, the telescopic assembly can swing around the first axis to adjust the angle of spraying the insulating liquid.

[0084] Optionally, one of the first seat 210 and the connecting sleeve 610 is provided with an annular protrusion 211 and the other is provided with an annular groove 614. The annular protrusion 211 is inserted into the annular groove 614, thereby limiting the first seat 210 in the connecting sleeve 610 and improving the stability of the first seat 210.

[0085] Optionally, the base assembly 200 also includes a bearing 230, which is disposed in the first base 210. The second base 220 is rotatably connected to the first base 210 through the bearing 230, which can reduce the frictional resistance of the second base 220 and improve the smoothness of rotation of the second base 220.

[0086] like Figure 1 and Figure 8As shown, the shearing and clamping device 300 includes a second support base 310, a first support arm 320, a second support arm 330, a fifth driving member 340, a sixth driving member 350, and a shearing and clamping assembly 360. The second support base 310 is disposed on the base assembly 200. The first support arm 320 is rotatably connected to the second support base 310. The second support arm 330 slides along the length of the first support arm 320. The fifth driving member 340 is disposed on the second support base 310 and configured to drive the first support arm 320 to rotate relative to the second support base 310. The sixth driving member 350 is disposed on the first support arm 320 and configured to drive the second support arm 330 to slide relative to the first support arm 320. The shearing and clamping assembly 360 is disposed at the end of the second support arm 330 away from the first support arm 320 and configured to cut and clamp the cable. This setup eliminates the need for frequent adjustments to the overall posture of the insulating rod 100, reducing the swing amplitude of the insulating rod 100, improving the stability and accuracy of the shearing operation, reducing the operator's workload, and increasing maintenance efficiency.

[0087] Optionally, during operation, the fifth drive member 340 drives the first support arm 320 to rotate and lift, while the sixth drive member 350 operates synchronously to provide driving force to the second support arm 330, causing the second support arm 330 to extend along the first support arm 320. The lifting angle of the first support arm 320 and the extension length of the second support arm 330 can be adjusted via the control components integrated on the rod 110 to improve the accuracy of the shearing and clamping actions. In this embodiment, the fifth drive member 340 is a fifth motor, and the sixth drive member 350 is a hydraulic cylinder or an electric cylinder.

[0088] Optionally, the shearing and clamping assembly 360 includes a blade holder 361, a clamping seat 362, a blade head 363, a chuck 364, and a seventh driving member. The blade holder 361 and the clamping seat 362 are fixed on the second support arm 330. The blade head 363 and the chuck 364 are rotatably connected to the blade holder 361 and the clamping seat 362, respectively. The seventh driving member is configured to drive the blade head 363 and the chuck 364 to move synchronously, thereby cutting and clamping the wire. In this embodiment, the seventh driving member is a sixth motor. The blade head 363 and the chuck 364 are both coaxially fixed to the transmission shaft. The transmission shaft is connected to the output end of the sixth motor. The sixth motor drives the transmission shaft to rotate, thereby realizing the synchronous movement of the blade head 363 and the chuck 364.

[0089] Optionally, the clamp 364 is made of a flexible material, such as rubber or silicone, to prevent damage to the wire when clamping it. Furthermore, the clamp 364 has multiple serrations on one edge facing the clamping base 362 to increase friction with the wire, thereby improving the stability of the wire clamping.

[0090] Optionally, the insulating rod 100 is also provided with a directional key 130 and an indicator light 140. The directional key 130 and the indicator light 140 are respectively connected to the control component. The directional key 130 is used to control the operation of the shearing clamping device 300, the spraying device 400 or the image acquisition component 700.

[0091] Optionally, the base assembly also includes a storage battery, which is electrically connected to the shearing clamping device 300, the spraying device 400, the image acquisition component 700, the display screen 120, and the control component, respectively, to provide power to the aforementioned components.

[0092] Optionally, the power system operation and maintenance tool also includes a housing 800 and a door. The housing 800 is mounted on the base assembly 200, specifically on the second seat 220 of the base assembly 200. The housing 800 covers the shearing clamping device 300 and the spraying device 400. The door is slidably connected to the housing 800. In the non-operating state, after the door is closed, the housing 800 and the door can protect the shearing clamping device 300 and the spraying device 400, reducing the entry of dust, moisture, and foreign objects into the housing 800, reducing the risk of damage to the spraying device 400 and the shearing clamping device 300 from external impacts, and improving the stability and service life of the equipment.

[0093] When the power equipment operation and maintenance tool provided in this embodiment is applied to the operation and maintenance of power lines such as service lines in old residential areas and rural areas, the working process is roughly as follows:

[0094] First, the operator selects an appropriate number of rods 110 according to the height of the faulty or aging conductor (hereinafter referred to as the conductor) and connects them sequentially by thread to form an insulating rod 100. The operator then adjusts the position of the counterweight 510 in the axial direction of the insulating rod 100 through the operating component 520, which effectively counteracts the extra torque generated by the increase of the lever arm and minimizes the physical exertion and muscle load on the operator during the lifting and operation process.

[0095] Then, the operator slowly raises the shearing clamping device 300, bringing it close to the wire so that the wire is inside the opening of the shearing clamping device 300. While the wire is being cut, the clamp 364 clamps the wire. After the wire is cut, the clamp 364 and the clamping seat 362 together clamp the cut part (called the broken wire) and do not let go. The operator then slowly lowers the height of the shearing clamping device 300 at the top of the insulating rod 100 and then removes the broken wire.

[0096] Finally, after the operator removes the broken wire from the shearing clamping device 300, the spraying device 400 is lifted to the position of the high wire using the insulating rod 100. The spraying device 400 is then used to spray the cut surface of the wire to achieve the effect of insulation protection.

[0097] It should be noted that the shearing clamping device 300 and the spraying device 400 can work together. That is, after the shearing clamping device 300 clamps and cuts the conductor, the spraying device 400 sprays insulating liquid onto the cut surface of the conductor, thereby achieving integrated operation of conductor cutting and insulation protection, improving maintenance efficiency and operational safety. In other embodiments, the shearing clamping device 300 can be used alone to clamp and cut faulty conductors, aging conductors, or conductors to be replaced; the spraying device 400 can be used alone to spray insulating liquid onto the cut surface of the conductor to provide insulation protection for the exposed conductor.

[0098] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
