Description

Technical Field

[0001] This invention belongs to the technical field of power distribution line maintenance equipment, and specifically relates to a cable marking device for locating faults in power distribution lines. Background Technology

[0002] Power distribution lines are the core infrastructure for power transmission, and their operational status directly affects the stability and reliability of power supply. During long-term operation, power distribution lines are susceptible to damage, leakage, and line breakage due to various factors such as environmental erosion, external force damage, and line aging. Maintenance personnel need to promptly identify the fault locations and carry out repair work.

[0003] Currently, the industry commonly uses marking devices that travel along high-altitude power distribution lines to mark fault locations for accurate subsequent maintenance. However, existing cable marking devices have shortcomings in practical use: high-altitude power distribution lines are exposed to the outdoors year-round and are highly susceptible to wind disturbances and swaying. Existing devices, when traveling along power distribution lines, are typically attached to the lines via wheels. These wheels usually have a recessed design in the middle, engaging with the outside of the power distribution line through a recessed groove, resulting in generally poor stability. The fit between the wheels and the power distribution line is unstable; under wind conditions, the power distribution line can sway, and the recessed groove in the wheel can easily detach from the line, causing the entire device to lose support and potentially fall from a height. This not only damages the equipment and increases maintenance costs, but also poses a safety hazard of injuring personnel on the ground and damaging ground facilities, seriously affecting the safety and stability of power distribution line inspection and marking operations, and failing to meet the needs of routine high-altitude power distribution line fault location and marking operations. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing cable marking devices for locating faults in power distribution lines, such as cumbersome operation, easy fall, and insufficient safety.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cable marking device for locating faults in power distribution lines, comprising: The main body has a hanging ring fixedly installed on its upper part for hanging and pulling the main body, and a base plate horizontally installed on its lower part for placing the tagging mechanism. The walking mechanism includes a driving wheel and a driven wheel. Both the driving wheel and the driven wheel are provided with a housing. Inside the housing, a wheel body is rotatably mounted via bearings. A wheel-side motor is fixedly mounted outside the housing of the driving wheel. The output shaft of the wheel-side motor passes through the housing and is fixedly connected to the wheel body. The output shaft of the wheel-side motor and the wheel body can be connected by a reducer or the like. Furthermore, to increase power, a wheel-side motor can also be installed on the outside of the driven wheel; A stabilizing mechanism is symmetrically arranged on the left and right sides of the main body. Both stabilizing mechanisms are connected to the main body through stabilizing links. The stabilizing mechanism is used to maintain the stability of the main body outside the power distribution line. A drive link is provided between the stabilizing mechanism and the driving wheel and the driven wheel. The tagging mechanism is fixedly installed on the upper side of the base plate and is used to mark the fault location of the power distribution line.

[0006] The upper part of the hanging ring is arc-shaped, which facilitates the balanced hanging of the main body. The bottom of the base plate is detachably equipped with a balance block, which can adjust the overall center of gravity of the device and improve walking stability.

[0007] The stabilizing mechanism includes a sleeve and a guard arm. A drive block is movably disposed inside the lower side of the sleeve, and the drive block can move up and down along the inside of the sleeve. The drive block is fixedly connected to a drive linkage. A crank is symmetrically disposed on the side of the sleeve, and the middle part of the crank is hinged to the sleeve. A first linkage is hinged between the upper end of the crank and the outer end of the drive block. The lower end of the crank is hinged to the upper outer end of the guard arm. An auxiliary linkage is hinged between the lower end of the sleeve and the upper middle part of the guard arm. The auxiliary linkage is used to assist the opening and closing action of the guard arm. A protective groove for the passage of power distribution lines is provided inside the guard arm.

[0008] The upper side of the sleeve is provided with an inner groove, and the upper side of the drive block is fixedly provided with a plug rod. The plug rod is inserted into the inner groove, and a return spring is provided between the upper end of the plug rod and the inner groove. The return spring pushes the plug rod to move downward.

[0009] A limiting piece is fixedly provided at the upper end of the insertion rod. The diameter of the limiting piece is larger than the diameter of the insertion rod, which is used to limit the sliding stroke of the insertion rod and prevent the insertion rod from leaving the inner groove.

[0010] The guard groove is arc-shaped, and ball bearings are rotatably installed inside the groove. This reduces the frictional resistance between the guard arm and the power distribution line, ensuring smooth movement of the device and improving the clamping and fitting effect.

[0011] The tagging mechanism includes a placement cylinder and an electric cylinder. The placement cylinder is fixedly connected to the base plate via support legs. A top block is slidably disposed inside the placement cylinder. A pusher spring is disposed between the top block and the placement cylinder. Multiple tag rings are placed on the side of the top block away from the pusher spring. A discharge port is disposed at the end of the placement cylinder away from the support legs. A pusher port is disposed on the lower side of the placement cylinder corresponding to the discharge port. The position of the electric cylinder corresponds to the pusher port. A pusher plate is disposed at the output end of the electric cylinder. The upper end of the pusher plate is inserted into the pusher port via a top head.

[0012] The placement cylinder has an open design at one end near the discharge port, and a plug is screwed inside to facilitate the replenishment of the marking rings inside the placement cylinder.

[0013] The upper part of the marking ring is provided with an opening, and an arc-shaped pin is fixedly provided at the opening.

[0014] A limiting strip is fixedly installed inside the placement cylinder along its length. The limiting strip cooperates with the pin and is used to keep the marking ring opening facing upwards.

[0015] This invention provides a cable marking device for locating faults in power distribution lines, which has the following advantages: This invention features a symmetrical stabilizing mechanism. Through a drive linkage, a drive block, a crank, and an auxiliary link, the protective arms on both sides can adaptively open and close, clamping the power lines. Relying on the device's own weight, the protective arms automatically close to clamp the power lines, achieving line encirclement and limiting without additional electrical control. Combined with the balance block adjustment device at the bottom of the base plate, the device's center of gravity can be adjusted to effectively counteract the disturbance of high-altitude winds, preventing the wheels from detaching from the power lines and solving the problem of the device falling from heights. This significantly improves the safety and stability of high-altitude inspection and marking operations.

[0016] The walking mechanism is driven independently by wheel-side motors and can be configured with single-wheel or dual-wheel drive as needed. It has sufficient power and strong walking controllability. Combined with the arc-shaped hanging ring balance traction structure, it further improves the overall balance of the device and is suitable for inspection and marking scenarios of high-altitude power distribution lines, with a wide range of applications.

[0017] The automated marking mechanism uses an electric cylinder, a pusher spring, and a top block to automatically discharge and precisely clamp the marking rings. The marking action is completed automatically, eliminating the need for manual high-altitude operation and reducing the risk of manual maintenance. At the same time, the limit strip and the marking ring pins work together to ensure that the marking rings are arranged neatly, avoiding material jamming and ensuring high equipment stability.

[0018] The entire device can be hoisted and deployed by drones, eliminating the need for manual high-altitude climbing operations, reducing the risks of manual operation and maintenance, and is suitable for fault marking operations on high-altitude and long-distance power distribution lines, with a wide range of applications.

Detailed Implementation

[0031] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0032] Please see Figures 1 to 3 A cable marking device for locating faults in power distribution lines, comprising a main body 1, a traveling mechanism 3, a stabilizing mechanism 4, and a marking mechanism 2.

[0033] The top of the main body 1 is fixedly welded with an arc-shaped hanging ring 102, which can be adapted to the hook of the drone for hoisting, so as to realize the rapid deployment of the device at high altitude and ensure uniform force and stable balance during hoisting. The bottom of the main body 1 is horizontally fixedly installed with a base plate 101. The bottom of the base plate 101 is detachably installed with a balance block 1011 by bolts. The counterweight can be adjusted according to the working environment to optimize the overall center of gravity of the device and avoid deviation and swaying during movement. The upper surface of the base plate 101 is the mounting bearing surface of the tagging mechanism 2. The left and right sides of the main body 1 are symmetrically fixed with stabilizing connecting rods 103 for connecting and fixing the stabilizing mechanism 4.

[0034] The walking mechanism 3 includes a driving wheel 301 and a driven wheel 302 arranged in a front-to-back configuration. Both the driving wheel 301 and the driven wheel 302 are composed of a housing 3011, a wheel body 3012, and a bearing. The wheel body 3012 is rotatably mounted inside the housing 3011 through the bearing, ensuring smooth rotation without jamming. A wheel-side motor 3013 is fixedly mounted on the outside of the housing 3011 of the driving wheel 301. The output shaft of the wheel-side motor 3013 passes through the housing 3011 and is fixedly connected to the wheel body 3012. A reducer can be selected to match the transmission according to the walking requirements to improve torque and walking stability. In a preferred embodiment, a wheel-side motor 3013 can be simultaneously installed on the outside of the driven wheel 302 to achieve synchronous drive of the two wheels, which greatly improves the walking power of the device on inclined and bent power distribution lines.

[0035] In this embodiment, the entire device is hoisted to the high-altitude power distribution line 5 by attaching the hook to the hanging ring 102 via the drone hook, so that the wheels 3012 of the walking mechanism 3 are suspended on the power distribution line 5. A stabilizing mechanism is used to maintain the stability of the main body on the outside of the power distribution line. The wheel-side motor 3013 is started to drive the wheels 3012 to rotate, and the device moves at a constant speed along the power distribution line 5. A marking mechanism is fixedly installed on the upper side of the base plate; this marking mechanism is used to mark fault locations on the power distribution line.

[0036] Please see Figures 4 to 8In another embodiment, the left and right sets of stabilizing mechanisms 4 are arranged symmetrically and fixed to the main body 1 by stabilizing connecting rods 103. The driving block 403 of each set of stabilizing mechanisms 4 is fixedly connected to the outer shell 3011 of the walking mechanism 3 by driving connecting rods 401. The sleeve 402 of the stabilizing mechanism 4 is a fixed base. A sliding cavity is opened inside the sleeve 402, and the driving block 403 is slidably assembled inside the cavity. An inner groove 4021 is opened on the upper side of the sleeve 402. A vertically inserted rod 4034 is fixed on the top of the driving block 403. The top end of the rod 4034 extends into the inner groove 4021 and is fixed with a limiting piece 4035. The diameter of the limiting piece 4035 is larger than the diameter of the rod 4034 to prevent the rod 4034 from slipping. A return spring 4022 is installed inside the inner groove 4021. The return spring 4022 is sleeved on the outside of the rod 4034, and its two ends abut against the top wall of the inner groove 4021 and the limiting piece 4035 respectively, continuously applying a downward pushing force to the rod 4034.

[0037] The sleeve 402 is symmetrically hinged with crank rods 4031 on both sides. The middle of the crank rod 4031 is the hinge fulcrum. The upper end of the crank rod 4031 is hinged to the outer end of the drive block 403 through the first connecting rod 4032, and the lower end of the crank rod 4031 is hinged to the outer end of the guard arm 404. The bottom end of the sleeve 402 is hinged to the auxiliary connecting rod 4033, and the bottom end of the auxiliary connecting rod 4033 is hinged to the middle of the guard arm 404, forming a four-bar linkage structure to ensure that the opening and closing action of the guard arm 404 is smooth, synchronous and without deviation. The inner side of the guard arm 404 has an arc-shaped protective groove 4041 that matches the outer diameter of the power distribution line 5. Several freely rotatable ball bearings 4042 are evenly embedded inside the protective groove 4041 to minimize friction loss between the device and the line when the device moves.

[0038] In this embodiment, the entire device is hoisted to the high-altitude power distribution line 5, so that the wheels 3012 of the walking mechanism 3 are suspended on the power distribution line 5. The device presses down on the walking mechanism 3 under its own weight, and the drive block 403 is pulled up along the sleeve 402 by the drive linkage 401. The linkage crank 4031, the first linkage 4032 and the auxiliary linkage 4033 drive the left and right guard arms 404 to close inward synchronously, so that the guard groove 4041 hugs and clamps the power distribution line 5, thus completing the stable fixation of the device and preventing the walking mechanism from detaching from the power distribution line.

[0039] After the operation is completed, the drone lifts the hanging ring 102, and the entire device is lifted up under the force. The weight of the device is no longer pressing on the walking mechanism. The walking mechanism 3 releases the tension on the drive linkage 401 at the same time. The reset spring 4022 pushes the insertion rod 4034 and the drive block 403 to move down. The linkage guard arm 404 automatically opens and releases the clamp on the power distribution line 5. The entire device can then be lifted away, completing all operations.

[0040] Please see Figures 9 to 11In another embodiment, the tagging mechanism 2 is fixed to the upper side of the base plate 101. The placement cylinder 201 is fixed to the base plate 101 by the support leg 2011 provided at the bottom. The interior of the placement cylinder 201 is a hollow storage structure. The top block 2012 is slidably assembled on the right end inside the placement cylinder 201. A push spring 2013 is fixed between the right side of the top block 2012 and the end wall of the placement cylinder 201. The push spring 2013 always applies a leftward push force to the top block 2012, pushing the tag ring 203 to fit and arrange itself towards the discharge port 2014.

[0041] A discharge port 2014 is opened at the left end of the placement cylinder 201, and a push port 2015 is opened at the bottom corresponding to the discharge port 2014. An electric cylinder 202 is fixedly installed on the base plate 101 and located directly below the push port 2015. The telescopic end of the electric cylinder 202 is fixed with a push plate 2021. The top of the push plate 2021 is integrally formed with a top head 2022. The top head 2022 can be accurately inserted into the push port 2015 and push the outermost marking ring 203 to complete the wire marking.

[0042] The right end of the placement cylinder 201 has an opening, and a plug 2017 is screwed into the opening. By unscrewing the plug 2017, the marking rings 203 can be added into the cylinder through the storage port 2016, making loading convenient and quick. The top side of the placement cylinder 201 is fixed with a limiting strip 2018, and the top opening of the marking rings 203 is fixed with an arc-shaped pin 2031. The pin 2031 and the limiting strip 2018 fit together to keep all the marking rings 203 in an upward-facing state, avoiding stacking disorder and jamming, and ensuring continuous marking operation.

[0043] In this embodiment, the plug 2017 is first unscrewed, and the marking rings 203 are filled into the placement cylinder 201. The marking rings 203 are neatly arranged with the limiting strip 2018 and the pin 2031 in alignment. After filling, the plug 2017 is locked. When the fault location is reached, the control system activates the electric cylinder 202. The electric cylinder 202 extends, driving the pusher plate 2021 and the top head 2022 upwards, pushing out the marking rings 203 at the outlet 2014 and locking them at the fault location of the power distribution line 5, thus completing the fault marking. After a single marking operation, the electric cylinder 202 resets, and the pusher spring 2013 pushes the top block 2012 forward, replenishing the marking rings 203 to the outlet 2014 position, awaiting the next marking operation.
