Description

Technical Field

[0001] This invention relates to the field of power line maintenance technology, and in particular to a convenient auxiliary tool for power line maintenance. Background Technology

[0002] Power lines are the infrastructure for transmitting and distributing electrical energy. They consist of conductors, towers, insulators, and fittings, connecting power plants, substations, and end users. To ensure the stable and reliable operation of power distribution, power line maintenance has become an indispensable part of the process.

[0003] In related technologies, power line maintenance is generally carried out manually. Workers first climb the tower (by climbing or using a lifting device to raise the workers), and then the workers drive the flying vehicle equipment and use handheld testing instruments to inspect the power line.

[0004] However, manual operation is not only a waste of time and energy and has low work efficiency, but also poses certain safety hazards. When operators drive the vehicle, the failure of the safety belt or equipment may lead to collisions or falls. At the same time, when in close contact with live lines, electric shock may occur due to insufficient safety distance or equipment insulation failure. Summary of the Invention

[0005] The purpose of this invention is to solve the problems of wasted time and effort and safety hazards associated with manual labor in the prior art. It proposes a convenient auxiliary tool for power line maintenance, which can replace manual labor, making power line maintenance more efficient and convenient, while reducing the occurrence of accidents.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: A portable auxiliary tool for power line maintenance includes a maintenance mechanism and a walking mechanism connected to the maintenance mechanism for moving the maintenance mechanism on the power line. The maintenance mechanism includes a support ring, a drive assembly, and a detection component. The support ring is fixedly connected to the walking mechanism. The support ring has a first notch for the power line to pass through. The support ring is provided with a support plate. The support ring is provided with a number of guide wheels along its circumference.

The driven wheel and the second gear are both fixedly mounted on the driven shaft. The timing belt is sleeved on the drive wheel and the driven wheel. The first gear and the second gear are both located inside the guide wheel. The gear ring is located between the guide wheel, the first gear, and the second gear. The gear ring meshes with the first gear and the second gear. A second notch is provided on the gear ring for the passage of power lines. The detection component is mounted on the toothed ring and can rotate with the toothed ring to detect the power line.

[0007] Furthermore, based on the above solution, the walking mechanism includes a bracket, a first pulley assembly, and a second pulley assembly. The bracket is fixedly connected to a support ring, and the first pulley assembly and the second pulley assembly are respectively installed at both ends of the bracket. The first pulley assembly and the second pulley assembly can move on the power line.

[0008] Furthermore, based on the above scheme, both the first pulley assembly and the second pulley assembly include a pulley frame and a pulley mounted on the pulley frame. The pulley frame of the first pulley assembly is rotatably mounted on one end of the bracket, and the pulley frame of the second pulley assembly is rotatably mounted on the other end of the bracket.

[0009] Furthermore, based on the above solution, the first pulley assembly also includes a second motor, which is fixedly installed on the outside of the pulley frame of the first pulley assembly, and the pulley is fixedly connected to the output shaft of the second motor.

[0010] Furthermore, based on the above solution, the walking mechanism also includes a locking component for locking the pulley frame onto the bracket. The locking component includes a first screw hole mounting block, a second screw hole mounting block, and a bolt. The first screw hole mounting block and the second screw hole mounting block are respectively fixedly installed on the pulley frame and the bracket. The bolt is installed on the first screw hole mounting block and works in conjunction with the first screw hole mounting block and the second screw hole mounting block.

[0011] Furthermore, based on the above solution, the walking mechanism also includes an auxiliary support assembly for locking the pulley frame onto the bracket. The auxiliary support assembly is located below the pulley and includes an adjustment hole, a connecting shaft, a support pulley, and a nut. The adjustment hole is opened on the bracket, the connecting shaft is installed in the adjustment hole and has threads at both ends that are adapted to the nut, the support pulley is rotatably installed on the connecting shaft and is located below the pulley, and the nut is installed on the connecting shaft and is tightly fitted to the bracket.

[0012] Furthermore, based on the above solution, the maintenance mechanism also includes a detachable component for installing and removing maintenance parts. The detachable component includes a fixing component and a detachable component. The fixing component is fixedly installed on the gear ring, and the detachable component is detachably installed on the fixing component. The maintenance part is fixedly installed on the detachable component. The detachable component has a movable groove inside, and a buckle is provided in the movable groove. An elastic element for buckle reset is also provided in the movable groove. One end of the buckle is connected to the buckle, and the other end is connected to the detachable component. The fixing component has a slot, which cooperates with the buckle.

[0013] Building upon the above solution, the detachable components are further provided in two form, symmetrically distributed on the toothed ring.

[0014] Furthermore, based on the above scheme, the width L1 at the minimum point of the second gap is less than the center distance L2 between the first gear and the second gear.

[0015] Furthermore, based on the above solution, a control box is also included. The control box is fixedly installed below the bracket. The control box contains a PCB board and a power supply. The PCB board is electrically connected to the power supply, the first motor, and the second motor.

[0016] Compared with the prior art, the present invention has the following beneficial effects: This invention includes an inspection mechanism and a traveling mechanism. The inspection mechanism can inspect power lines, and the traveling mechanism can move the inspection mechanism along the power lines. It can replace manual inspection of power lines, making inspection more convenient, improving work efficiency, and reducing safety hazards.

[0017] The driving component of this invention can drive the detection element to move in a circular motion around the power line. Driven by the traveling mechanism, it can then detect the position of the outer circumference of the entire power line, thereby improving the accuracy of the detection.

[0018] In this invention, the detection component is fixed on a detachable component, which is detachably installed on a fixed component. By disassembling and replacing the detachable component, different detection components can be installed, thereby enabling the detection of different indicators of the power line.

It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0023] like Figure 1-7 As shown, a convenient auxiliary tool for power line maintenance is used for the inspection of power line 4. It includes a maintenance mechanism 1 and a walking mechanism 2 connected to the maintenance mechanism 1 and used to move the maintenance mechanism 1 on the power line 4. The walking mechanism 2 moves the maintenance mechanism 1 on the power line 4, thereby replacing manual operation. It has the advantages of convenience, efficiency and safety.

[0024] Please refer to the following for details. Figure 3-5 The maintenance mechanism 1 includes a support ring 101 fixedly connected to the walking mechanism 2. The support ring 101 is a ring structure with a notch, called the first notch 1011, which is used to allow the power line 4 to pass through, so that the power line 4 is located inside the support ring 101. A support plate 1012 is provided on the support ring 101. Five guide wheels 1013 are provided on the support ring 101 along its circumference. The five guide wheels 1013 are symmetrically and rotatably mounted on the support ring 101.

[0025] Furthermore, the maintenance mechanism 1 also includes a drive assembly. Specifically, the drive assembly includes a first motor 103, a drive shaft 104, a drive wheel 105, a first gear 106, a driven shaft 107, a driven wheel 108, a second gear 109, a synchronous belt 110, and a gear ring 111. The first motor 103 is fixedly mounted on one end of the support plate 1012. The drive shaft 104 is fixedly mounted on the output shaft of the first motor 103. The drive wheel 105 and the first gear 106 are both fixedly mounted on the drive shaft 104. The driven shaft 107 is rotatably mounted on the other end of the support plate 1012. The driven wheel 108... Both the first gear 106 and the second gear 109 are fixedly mounted on the driven shaft 107. The synchronous belt 110 is sleeved on the driving wheel 105 and the driven wheel 108. The first gear 106 and the second gear 109 are both located inside the guide wheel 1013. The gear ring 111 is located between the guide wheel 1013, the first gear 106 and the second gear 109. The gear ring 111 meshes with the first gear 106 and the second gear 109. The gear ring 111 has a ring structure with a notch, which is the second notch 1111. The second notch 1111 is used to pass through the power line 4, so that the power line 4 is located inside the gear ring 111. The first motor 103, drive shaft 104, drive wheel 105, driven shaft 107, driven wheel 108, and synchronous belt 110 constitute a synchronous motion mechanism. When the first motor 103 is working, it drives the drive shaft 104 to rotate, which in turn drives the first gear 106 to rotate, thereby driving the gear ring 111 to rotate. At the same time, under the action of the drive wheel 105, driven shaft 107, driven wheel 108, and synchronous belt 110, it can also drive the second gear 109 to rotate synchronously, so as to drive the gear ring 111 to rotate.

[0026] Furthermore, the width L1 at the minimum point of the second notch 1111 is less than the center distance L2 between the first gear 106 and the second gear 109; in this way, the gear ring 111 will mesh with at least one of the gears no matter what position it rotates to, ensuring that the gear ring 111 can always mesh and rotate under the action of the gears.

[0027] Furthermore, the maintenance mechanism 1 also includes a detection component 102, which is mounted on a gear ring 111. Under the action of the first gear 106 and the second gear 109, the gear ring 111 can make a circular motion around the power line 4. The detection component 102 can rotate with the gear ring 111, thereby performing a comprehensive inspection of the power line 4 and improving the accuracy of the inspection.

[0028] In this embodiment, the detection element 102 can be a temperature sensor, camera, infrared thermal imager, ultraviolet imager, and rangefinder, etc., used to detect different parameters.

[0029] In summary, the support ring 101 and the gear ring 111 are provided with notches, through which the power line 4 can be placed inside the gear ring 111, which is convenient and quick. At the same time, there are synchronously rotating first gear 106 and second gear 109. The gear ring 111 will always mesh with at least one of the gears, so that the gear ring 111 can always be driven by the gear to rotate, thereby driving the detection element 102 to make a circular motion around the power line 4, thereby performing a comprehensive inspection of the power line 4 and improving the accuracy of the inspection.

[0030] It is worth mentioning that the guide wheel 1013 is an H-shaped wheel or a U-shaped wheel. The guide wheel 1013 can restrict the rotation of the toothed ring 111, ensuring that the toothed ring 111 rotates along a fixed track. It can better wrap the toothed ring 111 and prevent the toothed ring 111 from derailing. At the same time, the guide wheel 1013 replaces sliding friction with rolling friction, which significantly reduces the resistance when the toothed ring 111 rotates, making the rotation more effortless and smoother.

[0031] It is worth mentioning that a counterweight block with a weight equivalent to that of the first motor 103 is provided at the other end of the support plate 1012 (the end opposite to the first motor 103). The counterweight block can be fixed to the support plate 1012 by screws or welding to balance the overall weight.

[0032] Please refer to the following for details. Figure 3 and 7 The maintenance mechanism 1 also includes a detachable component for installing and removing maintenance parts. The detachable component includes a fixing member 112 and a detachable member 113. The fixing member 112 is fixedly installed on the gear ring 111 and can be fixed to the gear ring 111 by screws or welding. The detachable member 113 is detachably installed on the fixing member 112, and the maintenance part is fixedly installed on the detachable member 113. The maintenance part can be glued to the detachable member 113 with adhesive. The detachable member 113 has a movable groove 1131 inside, and a latch 1132 is provided in the movable groove 1131. The latch 1132 can move within the movable groove 1131. The component 1 also includes an elastic element 1133 for resetting the latch 1132. One end of the latch 1132 is connected to the latch 1132, and the other end is connected to the detachable component 113. The fixing component 112 has a slot 1121, which works in conjunction with the latch 1132. By pressing the latch 1132, the latch 1132 is moved into the movable slot 1131, allowing the latch 1132 to enter or leave the slot 1121. At the same time, the elastic element 1133 is compressed, releasing the latch 1132 and resetting the elastic element 1133, thus facilitating the installation and removal of the maintenance component.

[0033] It is worth mentioning that there are two detachable components, which are symmetrically distributed on the toothed ring 111, meaning that two detection elements 102 can be mounted on the toothed ring 111. In this way, the symmetrical arrangement makes the load evenly distributed on the toothed ring 111, avoiding deformation or fracture caused by local stress concentration. At the same time, the symmetrical installation of the detection elements 102 can obtain more comprehensive data and avoid detection deviation.

[0034] In this embodiment, the elastic element 1133 is a spring.

[0035] It is worth mentioning that the end of the buckle 1132 protrudes from the movable groove 1131 to form a pressing part, which makes it convenient for the operator to press the buckle 1132.

[0036] It is worth mentioning that there are two symmetrically arranged buckles 1132 and elastic elements 1133, which can enhance structural reliability and improve stability.

[0037] Please refer to the following for details. Figure 1 and 7 The walking mechanism 2 includes a bracket 201, a first pulley assembly 202, and a second pulley assembly 203. The bracket 201 is divided into two parts, which are fixedly connected to the support ring 101 respectively. The first pulley assembly 202 and the second pulley assembly 203 are respectively installed at both ends of the bracket 201. The first pulley assembly 202 and the second pulley assembly 203 can move on the power line 4.

[0038] Furthermore, both the first pulley assembly 202 and the second pulley assembly 203 include a pulley frame 204 and a pulley 205 mounted on the pulley frame 204. The pulley frame 204 of the first pulley assembly 202 is rotatably mounted on one end of the bracket 201 via a pivot, and the pulley frame 204 of the second pulley assembly 203 is rotatably mounted on the other end of the bracket 201 via a pivot. In other words, the first pulley assembly 202 and the second pulley 205 are respectively mounted on both ends of the maintenance mechanism 1, which can improve stability and balance. Moreover, the pulley frame 204 can be rotated open, which facilitates the placement of the power line 4 inside the gear and avoids interference between the pulley frame 204 and the power line 4.

[0039] In this embodiment, all pulleys 205 are U-shaped wheels. The U-shaped wheels can better wrap around the power line 4, prevent derailment, and reduce wear on the power line 4.

[0040] Furthermore, the first pulley assembly 202 also includes a second motor 206, which is fixedly installed on the outside of the pulley frame 204 of the first pulley assembly 202. The pulley 205 is fixedly connected to the output shaft of the second motor 206. That is, the first pulley assembly 202 is a drive pulley 205 assembly. The motor can drive the pulley 205 of the first pulley assembly 202 to rotate, so that it can move on the power line 4, which facilitates the detection element 102 to detect the power line 4.

[0041] Furthermore, the walking mechanism 2 also includes a locking assembly for locking the pulley frame 204 onto the bracket 201. The locking assembly includes a first screw hole mounting block 207, a second screw hole mounting block 208, and a bolt 209. The first screw hole mounting block 207 and the second screw hole mounting block 208 are respectively fixedly mounted on the pulley frame 204 and the bracket 201. The bolt 209 is mounted on the first screw hole mounting block 207 and works in conjunction with the first screw hole mounting block 207 and the second screw hole mounting block 208. That is, the first screw hole mounting block 207 and the second screw hole mounting block 208 are provided with threaded holes for mounting the bolt 209. In this way, when the pulley frame 204 is fastened to the bracket 201, the pulley frame 204 can be fixed by rotating the bolt 209 and tightening it onto the first screw hole mounting block 207 and the second screw hole mounting block 208. Fixing the pulley frame 204 with the bolt 209 also makes it easy to release the pulley frame 204 and facilitates the rotation of the pulley frame 204.

[0042] Furthermore, the traveling mechanism 2 also includes an auxiliary support assembly for locking the pulley frame 204 onto the bracket 201. The auxiliary support assembly is located below the pulley 205 and includes an adjustment hole 210, a connecting shaft 211, a support pulley 212, and a nut 213. The adjustment hole 210 is formed on the bracket 201. The connecting shaft 211 is installed in the adjustment hole 210 and has threads at both ends that are compatible with the nut 213. The support pulley 212 is rotatably mounted on the connecting shaft 211 and is located below the pulley 205. The nut 213 is installed on the connecting shaft 211 and fits tightly against the bracket 201. Thus, by loosening the nut 213, the positions of the connecting shaft 211 and the support pulley 212 in the adjustment hole 210 can be adjusted so that the support pulley 212 supports the power line 4. By supporting the power line 4 with the support pulley 212, the traveling mechanism 2 is prevented from deviating too much during movement.

[0043] In this embodiment, the bolt 209 and nut 213 are wing bolts 209 and nut 213, which are easy to grip with fingers and enable quick operation.

[0044] Please refer to the following for details. Figure 1The portable power line maintenance auxiliary tool also includes a control box 3, which is fixedly installed below the bracket 201, lowering the center of gravity of the tool. This helps to suppress the tool's swaying and reduce shaking caused by inertia or wind, allowing the walking mechanism 2 to move smoothly. The control box 3 contains a PCB board and a power supply, which are electrically connected to the power supply, the first motor 103, and the second motor 206.

[0045] This invention is a convenient auxiliary tool for power line maintenance, and its working principle is explained in conjunction with the accompanying drawings: First, the lifting device lifts the operator to the position of the power line 4, turns on the first motor 103, drives the gear to rotate, so that the second notch 1111 of the gear faces upward and is aligned with the first notch 1011, opens the pulley frame 204 on the first pulley assembly 202 and the second pulley assembly 203, and at this time the walking mechanism 2 and the detection mechanism are in the open state, which makes it easy to put the power line 4 into the interior of the portable power line maintenance auxiliary tool.

[0046] Next, rotate the pulley bracket 204 on the first pulley assembly 202 and the second pulley assembly 203 so that the pulley bracket 204 is fastened to the bracket 201, and rotate the bolt 209 to screw the lower part of the bolt 209 into the second screw hole mounting block 208, thus completing the fixing of the pulley bracket 204 of the first pulley assembly 202 and the second pulley assembly 203. At this time, the pulleys 205 of the first pulley assembly 202 and the second pulley assembly 203 are in contact with the outer surface of the power line 4.

[0047] Then, adjust the height of the connecting shaft 211 and the support pulley 212 so that the support pulley 212 is as close as possible to the power line 4, but not in close contact with the power line 4. After adjustment, tighten the nut 213 so that the nut 213 is in close contact with the side wall of the bracket 201 and fixes the connecting shaft 211 and the support pulley 212.

[0048] Finally, the first motor 103 and the second motor 206 are started. The first motor 103 drives the detection element 102 to rotate and perform circumferential detection on the power line 4. The second motor 206 drives the pulley 205 on the first pulley assembly 202 to rotate, thereby driving the detection element 102 to move along the length of the power line 4 and perform length detection on the power line 4. This allows for the detection of the entire outer circumference of the power line 4, making it more efficient, convenient, and accurate.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
