Description

Technical Field

[0001] This invention relates to the field of power transmission line obstacle removal technology, and more specifically, to a fully automatic inspection and obstacle removal device for power transmission lines in mountainous areas. Background Technology

[0002] As the lifeline of power transmission, the stable operation of power transmission lines in mountainous areas is of paramount importance. However, these lines are exposed to complex natural environments year-round and are highly susceptible to various obstacles, including plant branches, ice, and potentially harmful plastic films. These obstacles can significantly reduce safety gaps, causing serious accidents such as line discharge, short circuits, and even power outages, threatening the safety of the power grid.

[0003] Existing technologies for inspecting and clearing obstacles on power transmission lines mostly rely on drones. However, drones are limited by the harsh terrain and weather conditions in mountainous areas. Moreover, remotely clearing obstacles such as plastic film is not only inefficient and difficult, but the film can also easily interfere with the drone's rotor. In particular, the airflow of the rotor can cause the obstacle to become increasingly entangled, and it can even enter the blade area and become entangled, which can not only interfere with the normal flight of the rotor, but may also lead to loss of control and safety accidents.

[0004] How to invent a fully automatic inspection and obstacle removal device for power transmission lines in mountainous areas to improve these problems has become an urgent issue for those skilled in the art. Summary of the Invention

[0005] To overcome the above deficiencies, the present invention provides a fully automatic inspection and obstacle clearing device for power transmission lines in mountainous areas, which aims to improve the problems mentioned in the background art.

[0008] The drive mechanism includes a gear ring, gear one, and gear two rotatably connected inside the box. A gear set is provided between the drive shafts of gear one and gear two. Gear set one and gear set two are provided on the inner side of the gear ring. A motor three that drives gear one is provided inside the box. The gear ring is driven by gear one and gear two, which in turn drive the transmission block to swing and clear obstacles.

[0009] Preferably, the lifting plate is provided with a set of driven wheels that cooperate with the drive wheel, which can close with the drive wheel to form a circular channel when the lifting plate rises.

[0010] Preferably, the two sets of gears connected to the drive shafts of gear one and gear two for transmission have the same parameters, so that gear one transmits power to gear two through the gear sets, only changing the direction of rotation, and gear one and gear two rotate at the same speed.

[0011] Preferably, gear set one and gear set two are designed to be staggered along the axis of the gear ring. Gear one meshes with gear set one, and gear two meshes with gear set two. Gear one and gear two are designed with missing gears. When the first set of transmission teeth of gear one begins to mesh with gear set one, the last set of transmission teeth of gear two just disengages from gear set two, thus achieving seamless reversing switching of the gear ring drive.

[0012] Preferably, the diameter of the cleaning roller is larger than the diameter of the cylinder formed by the combination of the take-up roller and the take-up hook, and the surface of the cleaning roller is provided with multiple sets of evenly spaced grooves.

[0014] Preferably, the support block is fixedly connected to the box body by a fixed rod, and the blade assembly has a sliding groove that matches the rod of the support block. During the reciprocating swing of the transmission block and the blade assembly, the swing amplitude is limited and will not affect or collide with the connecting rod of the support block.

[0015] Preferably, the side of the blade assembly away from the box body is designed with a first cutting tooth whose cutting direction is designed around the circumference of the blade assembly, and the side of the blade assembly away from the box body is also provided with a second cutting tooth distributed around the axis of the blade assembly and whose cutting direction is towards the axis of the blade assembly.

[0016] Preferably, a spring is provided between the detection block and the transmission block. A sealing groove 1 is provided on the top of the impact block.

[0018] In summary, the beneficial effects of this invention are:

[0019] 1. Through the cooperation of the drive wheel and the driven wheel, the operation is stable. The reverse rotation of gear one and gear two at the same speed drives the transmission block to rotate and swing back and forth. This not only effectively disrupts the balance of obstacles and accelerates their removal, but also avoids entanglement compared to rotary cleaning. The hidden blade design reduces contact and entanglement interference with films. The unidirectional rotation drive of the cleaning roller to the winding roller can efficiently capture and stably control the attached plastic film, ensuring the processing quality and efficiency of soft plastic waste.

[0020] 2. When clearing ice-covered obstacles on transmission lines, cutting teeth one and two are used to swing and rotate to cut the ice layer. At the same time, cutting teeth two on the end of the detection block shaft can efficiently grind the ice layer and generate vibration, thereby achieving efficient crushing and removal of the ice layer. The depth of the cutting group into the ice layer can be adjusted to move the detection block, and the degree of icing can be automatically monitored and evaluated. For general icing layers, the impact block is moved, stored, and reset to impact and destroy the ice on the surface of the transmission line. For deeper ice layers, the impact block and hydraulic block can be stored simultaneously to reduce the impact force of the impact block on the surface of the transmission line ice layer, improve the stress concentration effect of the impact, increase the efficiency of creating initial cracks, reduce the overall structural strength, and thus accelerate the rapid destruction of the ice layer.

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Reference Figure 1-11This invention provides a fully automatic inspection and obstacle clearing device for power transmission lines in mountainous areas, including a housing 100 and a traveling mechanism. The traveling mechanism includes a second motor 103 mounted on the side wall of the housing 100, with its output shaft connected to a drive wheel 105 for driving the device. A threaded rod 104 is disposed inside the housing 100, and a lifting plate 101 is threadedly connected to the side wall of the threaded rod 104. A first motor 102, which is connected to the threaded rod 104, is located at the bottom of the housing 100. A cleaning mechanism is also included. A transmission block 200 is rotatably connected to the box body 100. A cleaning roller 201 and a winding roller 202 are rotatably connected to the inner wall of the transmission block 200. A winding hook 203 for gripping and winding flexible plastic film is provided on the outer wall of the winding roller 202. A blade assembly 301 for cutting and clearing obstacles is connected to the side wall of the transmission block 200. A detection block 300 is movably sleeved on the side wall of the box body 100, and the detection block 300 is movably sleeved with the blade assembly 301. An impact block 500 is provided on the inner wall of the detection block 300, and the impact block 500 is movably sleeved with the detection block 301. A spring is installed between the 0 and 0 points. A drive groove 306 is opened inside the detection block 300. A drive block 307 is slidably connected inside the drive groove 306. A pull rope is installed between the drive block 307 and the impact block 500. A locking block 308 is sleeved inside the drive block 307. A support block 304 is fixedly connected to the box body 100. A set of fixing blocks 305 extending into the drive groove 306 are provided on the side wall of the support block 304. The fixing blocks 305 and the locking blocks 308 drive the impact block 500 to move and release, clearing the obstacle area. Impact cleaning is performed; the drive mechanism includes a gear ring 400, gear one 402, and gear two 403 rotatably connected inside the housing 100. A gear set 406 is provided between the drive shafts of gear one 402 and gear two 403 for transmission. Gear set one 404 and gear set two 405 are provided on the inner side of the gear ring 400. A motor three 401 that drives gear one 402 is provided inside the housing 100. The gear ring 400 is driven by gear one 402 and gear two 403, which in turn drives the transmission block 200 to swing and clear obstacles.

[0036] Furthermore, the lifting plate 101 is provided with a set of driven wheels that cooperate with the drive wheel 105. When the lifting plate 101 rises, it can close with the drive wheel 105 to form a circular channel, thereby ensuring stability when traveling on the conductor and preventing the conductor from detaching from the drive wheel 105.

[0037] It should be noted that the two sets of gear sets 406 connected to the drive shafts of gear one 402 and gear two 403 have the same parameters, so that gear one 402 transmits power to gear two 403 through gear set 406, only changing the direction of rotation, and gear one 402 and gear two 403 rotate at the same speed.

[0038] Furthermore, gear set 1 404 and gear set 2 405 are designed to be staggered along the axis of gear ring 400. Gear 1 402 meshes with gear set 1 404, and gear 2 403 meshes with gear set 2 405. Through the staggered design, during the transmission process between gear 2 403 and gear 1 402 and gear set 1 404, gear 1 402 and gear 2 403 do not contact or affect each other. Gear 1 402 and gear 2 403 are designed with missing gears. When the first set of transmission teeth of gear 1 402 begins to mesh with gear set 1 404, the last set of transmission teeth of gear 2 403 just disengages from gear set 2 405, realizing seamless reversing switching of the drive of gear ring 400.

[0039] Reference Figure 5 The diameter of the cleaning roller 201 is larger than the diameter of the cylinder formed by the combination of the take-up roller 202 and the take-up hook 203. The surface of the cleaning roller 201 is provided with multiple sets of evenly spaced grooves. Through the groove design of the cleaning roller 201, the stress during the contact process with the cable is increased. This not only further crushes, scrapes and breaks up the cleaning residue on the surface of the power transmission cable, but also drives the cleaning roller 201 to rotate through the contact with the cable. The small diameter take-up roller 202 can reduce and avoid direct contact with the cable, and avoid damage and deformation of the take-up hook 203.

[0040] Reference Figure 5-6 The drive shafts of the cleaning roller 201 and the take-up roller 202 are connected by a belt drive. The output shaft of the take-up roller 202 is also equipped with a ratchet 204 to drive the take-up roller 202 in one direction. By filtering the transmission direction, the take-up roller 202 can be rotated in one direction, so that the take-up roller 202 can be rotated in one direction to achieve winding and collection of plastic film components.

[0041] Reference Figure 3-7 The support block 304 is fixedly connected to the box body 100 through a fixed rod. The blade assembly 301 has a sliding groove that matches the rod of the support block 304. During the reciprocating swing of the transmission block 200 and the blade assembly 301, the swing amplitude is limited and will not affect or collide with the connecting rod of the support block 304.

[0042] Furthermore, the side of the blade assembly 301 away from the housing 100 is designed with a first cutting tooth 302 whose cutting direction is circumferentially around the blade assembly 301. The side of the blade assembly 301 away from the housing 100 is also provided with a second cutting tooth 303 distributed around the axis of the blade assembly 301 and whose cutting direction is towards the axis of the blade assembly 301. Through the multiple cleaning designs of the first cutting tooth 302 and the second cutting tooth 303, the first cutting tooth 302 can directly cut and clean obstacles along the circumference of the blade assembly 301, and the second cutting tooth 303 can swing, cut, grind and break obstacles in the direction of travel of the blade assembly 301.

[0043] Reference Figure 7-10A spring is provided between the detection block 300 and the transmission block 200. A sealing groove 502 is provided on the top of the impact block 500. A hydraulic block 501 is sleeved inside the sealing groove 502. The top of the hydraulic block 501 is connected to the drive block 307 by a pull rope. Sealing grooves 503 are provided on both sides of the bottom of the impact block 500. A protective block 504 is sleeved inside the sealing groove 503. A return pipe 506 and a one-way pipe 505 are provided between the sealing groove 502 and the sealing groove 503. The diameter of the one-way pipe 505 is larger than the diameter of the return pipe 506 and the flow direction of the one-way pipe 505 is towards the inside of the sealing groove 502. The flow direction of the return pipe 506 is towards the inside of the sealing groove 503. Hydraulic oil is filled between the hydraulic block 501 and the protective block 504. The bottom of the impact block 500 is designed as a sharp blade with a smaller cross-sectional area than the top.

[0044] Reference Figure 9 The bottom of the drive groove 306 is provided with a through groove 309. The top edge of the locking block 308 facing the through groove 309 is provided with a chamfer. The side of the locking block 308 away from the through groove 309 is provided with a limiting roller 311. The side wall of the fixing block 305 is provided with a limiting groove 310 that cooperates with the limiting roller 311. It should be noted that when the detection block 300 is not affected by external force, the limiting groove 310 does not contact the limiting roller 311.

[0045] The working process of this fully automatic inspection and obstacle removal device for mountain power transmission lines is as follows:

[0046] Starting from one end of the overhead line, motor 102 is first started, driving threaded rod 104 to rotate. Through the threaded transmission with lifting plate 101, a hole is made and lifting plate 101 moves downward, increasing the gap between drive wheel 105 and bottom driven wheel. The transmission line to be inspected passes through the gap between drive wheel 105 and bottom driven wheel, so that under the action of gravity, the drive wheel 105 hangs the entire box 100 on the transmission line. At the same time, the conductor enters through the notch of detection block 300 and transmission block 200, realizing... The near-alignment of the axis of the transmission block 200 and the detection block 300 facilitates subsequent cleaning of the transmission line surface. Furthermore, by rotating the motor 102 in the opposite direction, the lifting plate 101 is pushed upward toward the drive wheel 105, so that the drive wheel 105 is close to the driven wheel on the bottom lifting plate 101, forming a circular channel. During subsequent travel, even if the box 100 experiences shaking caused by wind, the drive wheel 105 can maintain its connection with the line, preventing it from becoming detached and thus ensuring stable transmission.

[0047] During obstacle clearing and inspection, starting motor 2 103 drives drive wheel 105 to rotate. During this rotation, the anti-slip design on the surface of drive wheel 105 moves the entire box 100 along the power transmission line. Simultaneously, motor 3 401 starts, driving gear 1 402 to rotate. Simultaneously, gear 1 402 and gear 2 403 are driven to rotate in opposite directions at the same speed via gear set 406 on their transmission shafts. Through the meshing transmission between gear 1 402 and gear set 1 404, when gear 1 402 rotates forward, it synchronously drives gear ring 400 to rotate forward, which in turn drives transmission block 200 to rotate in reverse until gear 1 402 reaches its maximum rotation speed. The last set of transmission teeth disengages from gear set 404. At this time, gear 2 403 rotates until the first set of transmission teeth contacts gear set 2 405. Thus, gear 2 403 reverses, causing gear ring 400 to reverse, which in turn causes transmission block 200 to rotate forward a certain distance until the last set of transmission teeth of gear 2 403 disengages from gear set 2 405. At this time, the first set of transmission teeth of gear 1 402 contacts gear set 404, causing transmission block 200 to reverse. This achieves the cyclical rotation and oscillation of transmission block 200, and the amplitude of the rotation and oscillation is greater than the notch of transmission block 200, thus achieving a thorough, dead-angle-free rotation and oscillation cleaning of the transmission line.

[0048] During the inspection and clearing process, the detection block 300 is positioned directly in front of the moving box 100. For flexible plastic film such as agricultural planting film or flexible plastic film in garbage attached to the power transmission line, under the elastic force of the spring between the detection block 300 and the transmission block 200 when no force is applied, the blade assembly 301 remains inside the detection block 300 and does not extend outside. Therefore, when plastic film or other attached materials pass by the detection block 300, they directly enter the area of ​​the transmission block 200 through the inner diameter of the detection block 300. The blade assembly 301 will not come into contact with low-resistance plastic film-like debris, thus preventing the breaking and clearing mechanism from tangling with the plastic. When plastic film waste enters the area where the transmission block 200 is located, under the rotational and oscillating action of the transmission block 200, the cleaning roller 201 contacts and rotates with the power line, and drives the ratchet 204 through the transmission belt. The ratchet 204 drives the take-up roller 202 in one direction, so that the take-up roller 202 can only rotate in one direction. During the unidirectional rotation of the take-up roller 202, the plastic film is captured through the large contact area of ​​the take-up hook 203. With the continuous unidirectional rotation of the take-up roller 202, the plastic film waste can be captured and stabilized by rotation. After the detection and obstacle removal are completed, it is taken out.

[0049] During the inspection and obstacle removal process, if non-flexible solid obstacles such as dead branches are encountered, when the box 100 moves, the detection block 300 comes into contact with the branches and debris. Under the pushing force of the obstacle, the detection block 300 moves towards the box 100, compressing the spring between the detection block 300 and the transmission block 200. At the same time, the detection block 300 moves to expose the blade assembly 301. Through the small-range reciprocating rotation and oscillation of the blade assembly 301, the cutting teeth 302 can perform reciprocating sawing cuts on the solid obstacles, significantly improving the cutting efficiency and destructive effect on plant obstacles. Bidirectional swinging motion can reduce entanglement and accumulation during the cutting and clearing process. Moreover, bidirectional swinging can efficiently disrupt the balance of obstacle accumulation, accelerating the falling and removal of obstacles after cutting and destruction. It should be noted that when laying high-altitude cables in mountainous areas, they are generally located above forests to reduce the impact of tree growth and spread on the lines. However, the natural environment in mountainous areas is complex. Under the action of wind, branches and leaves often hang on the transmission lines, forming obstacles. These obstacle structures generally have low bonding strength with the transmission lines and can be removed by rotation or cutting.

[0050] To address the icing obstacle, as the box 100 passes by, the detection block 300 presses against the ice, exposing the blade assembly 301. The cutting teeth 302 and 303 then oscillate and rotate to cut the ice layer. Simultaneously, the cutting teeth 303 at the shaft end of the detection block 300 efficiently grind and vibrate the ice layer, achieving efficient pulverization and removal. Furthermore, during the rotation and oscillation of the detection block 300, because the support block 304 is fixedly connected to the box 100, relative movement occurs between the support block 304 and the detection block 300. This causes the fixed block 305 to move during the rotation of the detection block 300. The right-angled side of the locking block 308 pushes the locking block 308 and the driving block 307 towards the through groove 309. The pull rope pulls the impact block 500, compressing the spring between the impact block 500 and the detection block 300. Because of the spring between the locking block 308 and the driving block 307, there is a thrust that pushes the locking block 308 towards the axis of the detection block 300. When the locking block 308 contacts the driving groove 306, because the bottom of the locking block 308 is in contact with the driving groove 306, it cannot be pushed to move. However, when the fixing block 305 moves the locking block 308 to the area of ​​the through groove 309, the locking block... Under the spring force of the drive block 307, 308 moves into the passage groove 309, allowing the drive block 307 to directly pass over the top of the locking block 308 and continue moving to the end of the drive groove 306. Under the spring force between the impact block 500 and the detection block 300, the drive block 307 resets towards the area where the impact block 500 is located. During the reset process of the drive block 307, the locking block 308 first contacts the side wall of the passage groove 309. The side wall of the passage groove 309 is provided with a chamfer, which allows the locking block 308 to be pushed upward from the bottom into the drive groove during the reset process of the drive block 307. Inside 306, the spring force between the impact block 500 and the detection block 300 is quickly released through the rapid sliding reset of the drive block 307 and the locking block 308. This allows the impact block 500 to be quickly released and reset, thus impacting the surface of the transmission line after ice breaking. The periodic impact energy resonates with the natural frequency of the ice layer, amplifying the stress effect. For general ice with weak adhesion and uniform thickness, it can quickly break the bond with the transmission line, achieving rapid cleaning of the surface ice. Moreover, the stress is dispersed and transmitted through the ice layer, avoiding potential damage to the cable sheath caused by concentrated load.

[0051] When the ice layer becomes deeper, including increased ice thickness and hardness, and the overall breaking down after cutting and grinding by the blade assembly 301 is slower, the blade assembly 301 will gradually penetrate deeper into the ice layer for further cutting and removal. At this point, the blade assembly 301 penetrates the ice layer to a greater depth, allowing the detection block 300 to move a longer distance through the ice. This results in relative movement between the fixed block 305 and the locking block 308 along the axis of the detection block 300. When the detection block 300 moves the locking block 308 to the position corresponding to the limiting roller 311 and the limiting groove 310, and during the swinging and rotating process of the detection block 300, the fixed block 305 moves the locking block 308 to the area of ​​the passage groove 309, where the locking engagement occurs between the limiting roller 311 and the limiting groove 310. The resistance from the incoming force prevents the locking block 308 from directly disengaging under the spring force between it and the driving block 307. The fixing block 305 moves the locking block 308 to the end of the driving groove 306 until the chamfered end of the locking block 308 contacts the edge of the driving groove 306. This contact between the edge of the driving groove 306 and the chamfered end of the locking block 308 generates a set of tangential stresses towards the axis of the detection block 300. This stress exceeds the locking force between the limiting roller 311 and the limiting groove 310, forcing the limiting roller 311 to rotate through the limiting groove 310 and pushing the locking block 308 towards the inside of the passage groove 309. This disengages the locking block 308 from the limiting force of the driving block 307. Then, following the reset process described above, the driving block 307 and the impact block 500 are reset and impacted. However... During this process, because the driving block 307 moves a longer distance in the driving groove 306 due to the movement of the locking block 308, after the driving block 307 moves and causes the impact block 500 to rise, compressing the spring between the impact block 500 and the detection block 300, the hydraulic block 501 can also be stretched and moved as the driving block 307 continues to move, thus reducing the internal pressure of the sealing groove 1 502. Furthermore, since the cross-sectional area of ​​the sealing groove 1 502 in the horizontal direction is much larger than that of the sealing groove 2 503 in the horizontal direction, the hydraulic block 501 can move a small distance and hydraulically drive the protective block 504 to move a large distance, exposing the sharp cutting end at the bottom of the hydraulic block 501. Moreover, since the hydraulic block 501 enters the sealing groove 1 502 unidirectionally through the sealing groove 2 503, The cross-sectional area of ​​the internal one-way pipe 505 is larger than the cross-sectional area of ​​the return pipe 506 that flows from the first sealing groove 502 into the second sealing groove 503. Therefore, after the hydraulic block 501 moves and drives the protective block 504 to rise, exposing the sharp section at the bottom of the impact block 500, during the reset process, the return flow of the first sealing groove 502 through the low-flow-area return pipe 506 is relatively slow. This allows the protective block 504 to gradually reset over time after the impact block 500 has fully reset and popped out, and after the sharp impact end at the bottom of the impact block 500 further impacts and vibrates the surface of the power transmission line after the surface ice layer has been removed. Moreover, during this process, due to the relative displacement between the hydraulic block 501 and the impact block 500, and the compression of the spring between the impact block 500 and the detection block 300, the protective block 504 will gradually reset over time.The reset distance remains the same: the drive block 307 resets first until the bottom of the locking block 308 contacts the chamfered edge of the through groove 309, and then the entire block quickly resets. Therefore, the elastic force of the impact block 500 during overall reset needs to be reduced by the elastic force generated by the spring tension between the hydraulic block 501 and the impact block 500. The actual impact force generated by the reset of the impact block 500 is less than the impact force generated by the reset under normal conditions. However, during impact, the impact part, which is a blunt body mixture composed of the hydraulic block 501 and the protective block 504, is changed to the sharp area at the bottom of the impact block 500. This allows for a smaller impact force and increased impact area strength when dealing with deeper ice layers. The sharp impact of the impact block 500 efficiently breaks and removes the remaining ice layer on the surface of the transmission line. Due to the greater thickness and adhesion of the deeper ice layer, the stress concentration effect is utilized. Taking advantage of the brittle nature of ice, initial cracks are created, significantly reducing its overall structural strength. The crack tip becomes a new stress concentration point, promoting continuous crack propagation and achieving rapid destruction of the ice layer. Moreover, because of the deeper ice layer, the sharp area of ​​the impact block 500 can avoid impacting and causing accidental damage to the transmission line. When the ice layer is shallow, the sharp area of ​​the impact block 500 will not directly impact the transmission line to prevent accidental damage caused by the shallow ice layer.

[0052] It should be noted that the drive groove 306 is provided with a set of recesses between the through groove 309 and the impact block 500. After the drive block 307 is reset, the locking block 308 is located directly above this set of recesses. The side wall of the recess is provided with a stop to restrict the locking block 308 from moving away from the through groove 309. Moreover, a set of spring plates is provided inside the recess to prevent the locking block 308 from entering the recess when it is not affected by external force. When the detection block 300 rotates in the opposite direction and the fixing block 305 passes by, the fixing block 305 can push the locking block 308 into this set of recesses through the angle of the locking block 308, so that the fixing block 305 can pass smoothly over the fixing block 305 and realize the cyclic operation.

[0053] The device is driven by drive wheel 105 to move to the other end of the power transmission line route. Workers can wait at the other end of the line in advance. After it reaches the end, the device can be unloaded and recycled. After the collected plastic film is removed and recycled, the next section of the line can be cleared and inspected.
