Description

Technical Field

[0001] This invention relates to the field of power transmission line cleaning technology, specifically to a device for removing foreign objects from power transmission lines. Background Technology

[0002] Because overhead power transmission lines are directly exposed to the natural environment, they are frequently entangled or suspended by foreign objects such as kite strings, plastic film fragments, fishing lines, branches, vines, and bird droppings. These objects not only seriously interfere with normal power transmission operations but may also pose a potential threat to power grid safety.

[0003] Traditionally, this problem has been addressed by high-risk, high-intensity methods such as manual climbing on electrified power lines. This approach is not only time-consuming and labor-intensive, but also inefficient. Furthermore, requiring workers to operate at heights and in electrified environments significantly increases the difficulty and safety risks. While laser cannons exist for clearing debris from overhead power lines, their operation requires precise aiming and focus adjustment to ensure accurate targeting and avoid unnecessary damage to the power lines. Moreover, as high-precision, high-tech equipment, laser cannons have relatively high procurement, maintenance, and training costs, hindering large-scale application.

[0004] Meanwhile, foreign objects are divided into hard foreign objects (twigs or vines) and soft foreign objects (bird droppings, plastic bags, kites, etc.). For hard foreign objects, operators need to cut them off, while for soft foreign objects, operators can use a drone equipped with a flame launcher to burn them. However, after the soft foreign objects are carbonized, they will still adhere to the power transmission line and cannot be completely removed.

[0005] The present invention aims to solve the technical problems existing in the prior art, and to this end, a foreign object removal device for power transmission lines is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a foreign object removal device for power transmission lines to solve the problems mentioned in the background art.

These cleaning devices are used to clean soft foreign objects from the surface of the power transmission line. The inner cylinder assembly is slidably connected to several cutting blades, each corresponding to a cleaning device. One end of each cutting blade extends into a cleaning device, and the cutting blades are used to cut hard foreign objects from the surface of the power line.

The connecting plate is threadedly connected to the UAV through the plurality of connecting bolts, and the support plate is fixedly connected to the outer cylinder assembly.

[0009] As a further aspect of the present invention: the outer cylinder assembly includes an outer cylinder, which is fixedly connected to a support plate. A limit rod is fixedly connected to the inner surface of the outer cylinder, and a ball is provided at the other end of the limit rod. The ball rolls in contact with the inner cylinder assembly. An annular bevel gear is fixedly connected to the inner surface of the outer cylinder, and the annular bevel gear meshes with a self-rotating mechanism.

[0010] As a further aspect of the present invention: the inner cylinder assembly includes an inner cylinder located within an outer cylinder. A groove is provided on the cylindrical surface of the inner cylinder, and a ball bearing is located in the groove and rolls in contact with the inner cylinder. The ball bearing limits the inner cylinder by cooperating with the groove. A transmission bevel gear is fixedly connected to one end of the inner cylinder, and the transmission bevel gear meshes with a drive mechanism. Several guide grooves are provided on one side of the inner cylinder, and several self-rotating mechanisms are rotatably connected to the cylindrical surface of the inner cylinder.

[0011] As a further embodiment of the present invention: the plurality of self-rotating mechanisms include a rotating shaft, which passes through the inner cylinder and is rotatably connected to the inner cylinder. A limit block is fixedly connected to the cylindrical surface of the rotating shaft, and the limit block is used to limit the rotation of the rotating shaft. A driven bevel gear is fixedly connected to one end of the rotating shaft, and the driven bevel gear meshes with an annular bevel gear. A spring is fixedly connected to the other end of the rotating shaft, and a cleaning device is slidably connected to the rotating shaft.

[0012] As a further embodiment of the present invention: the cleaning device includes a connecting rod, one end of which extends into a rotating shaft, a guide block is provided on the cylindrical surface of the connecting rod, and a turntable is fixedly connected to the other end of the connecting rod. The turntable is in contact with a spring, and a groove is provided on the cylindrical surface of the turntable. The groove cooperates with the cutter body, an adhesive layer is provided at the other end of the groove, and an adhesive plate is provided on one side of the groove. The groove is bonded to the adhesive plate through the adhesive layer, and a cleaning brush is fixedly connected to the other end of the adhesive plate.

[0013] As a further aspect of the present invention: the cutter body includes a plurality of cutters, the plurality of cutters are respectively located in a plurality of guide grooves and slide in contact with the inner cylinder, one end of each plurality of cutters is fixedly connected to a push rod, and the other end of each plurality of push rods extends into the slide groove and slides in contact with the turntable.

[0014] As a further embodiment of the present invention: the driving mechanism includes a driving motor, which is fixedly connected to a support plate. A driving shaft is fixedly connected to one side of the driving motor, and the other end of the driving shaft extends into the outer cylinder. A driving bevel gear is fixedly connected to the driving shaft, and the driving bevel gear is located in the outer cylinder and meshes with the transmission bevel gear.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. The transmission line passes through the inner cylinder assembly, wherein the spring acts on the cleaning device to ensure that the cleaning device is in close contact with the surface of the transmission line. At the same time, the cleaning device drives the cutter to move through the push rod, which can reduce the distance between the cutter and the transmission line. Then, the drone drives the connecting frame to move, and the connecting frame drives the inner cylinder assembly to move through the outer cylinder assembly. The inner cylinder assembly drives the cutter body to move to cut hard foreign objects that are not entangled in the transmission line. At the same time, it can avoid the situation where the distance between the cutter and the transmission line is too large, so that the cutter cannot cut the hard foreign objects entangled in the transmission line, and the distance between the cutter and the transmission line is too small, so that the cutter damages the transmission line.

[0016] 2. The inner cylinder assembly is driven to rotate by the drive mechanism. The inner cylinder assembly drives several self-rotating mechanisms to revolve around the sun. The self-rotating mechanisms drive the cleaning device to revolve around the sun. At the same time, during the revolve, the self-rotating mechanisms mesh with the outer cylinder assembly and rotate on their own axis. The self-rotating mechanisms drive the cleaning device to rotate on its own axis, thereby improving the cleaning device's ability to clean soft foreign objects adhering to the surface of the power transmission line. Meanwhile, the cleaning brush is bonded to the slide groove through the adhesive plate and adhesive layer, making it easy to remove the cleaning brush for cleaning after the surface of the power transmission line has been cleaned.

The inner cylinder assembly 3 is rotatably connected to several self-rotating mechanisms 5. The self-rotating mechanisms 5 pass through the inner cylinder assembly 3 and are used to drive the self-rotating mechanisms 5 to revolve.

[0027] Please see Figure 2-3 The outer cylinder assembly 2 includes an outer cylinder 201, which is fixedly connected to the support plate 101. A limiting rod 202 is fixedly connected to the inner surface of the outer cylinder 201, and a ball bearing 203 is provided at the other end of the limiting rod 202. The ball bearing 203 rolls in contact with the inner cylinder assembly 3. A ring bevel gear 204 is fixedly connected to the inner surface of the outer cylinder 201. The ring bevel gear 204 meshes with the self-rotating mechanism 5. During the revolution of the several rotating shafts 501, the driven bevel gear 502 meshes with the ring bevel gear 204, that is, the driven bevel gear 502 rotates under the action of the ring bevel gear 204 during the movement. The driven bevel gear 502 drives the rotating shaft 501 to rotate. The rotating shaft 501 drives the connecting rod 601 to rotate through the guide block 602. The connecting rod 601 drives the cleaning brush 607 to rotate through the turntable 603, the adhesive layer 605 and the adhesive plate 606, thereby improving the cleaning effect of the cleaning brush 607.

[0028] Please see Figure 2 and Figure 4 The inner cylinder assembly 3 includes an inner cylinder 301, which is located inside the outer cylinder 201. A groove 302 is provided on the cylindrical surface of the inner cylinder 301. A ball bearing 203 is located in the groove 302 and rolls in contact with the inner cylinder 301. The ball bearing 203 limits the inner cylinder 301 by cooperating with the groove 302. A transmission bevel gear 304 is fixedly connected to one end of the inner cylinder 301. The transmission bevel gear 304 meshes with the drive mechanism 4. Several guide grooves 303 are provided on one side of the inner cylinder 301. Several self-rotating mechanisms 5 are rotatably connected to the cylindrical surface of the inner cylinder 301.

[0029] Please see Figure 2The plurality of self-rotating mechanisms 5 include a rotating shaft 501, which passes through the inner cylinder 301 and is rotatably connected to the inner cylinder 301. A limiting block 503 is fixedly connected to the cylindrical surface of the rotating shaft 501, and the limiting block 503 is used to limit the rotating shaft 501. A driven bevel gear 502 is fixedly connected to one end of the rotating shaft 501, and the driven bevel gear 502 meshes with the ring bevel gear 204. A spring 504 is fixedly connected to the other end of the rotating shaft 501. A cleaning device 6 is slidably connected to the rotating shaft 501.

[0030] Please see Figure 1 and Figure 5 The cleaning device 6 includes a connecting rod 601, one end of which extends into a rotating shaft 501. A guide block 602 is provided on the cylindrical surface of the connecting rod 601. A turntable 603 is fixedly connected to the other end of the connecting rod 601. The turntable 603 is in contact with a spring 504. A groove 604 is provided on the cylindrical surface of the turntable 603. The groove 604 cooperates with the cutter body 7. An adhesive layer 605 is provided at the other end of the groove 604. An adhesive plate 606 is provided on one side of the groove 604. The groove 604 is bonded to the adhesive plate 606 through the adhesive layer 605. A cleaning brush 607 is fixedly connected to the other end of the adhesive plate 606. Several rotating shafts 501 and several connecting rods 601 drive the turntable 603 to revolve. That is, the turntable 603 drives the cleaning brush 607 to rotate through the adhesive layer 605 and the adhesive plate 606 to clean the soft foreign matter adhering to the surface of the power transmission line.

[0031] Please see Figure 1 and 3 The cutter body 7 includes a plurality of cutters 701, which are respectively located in a plurality of guide grooves 303 and slide in contact with the inner cylinder 301. One end of each cutter 701 is fixedly connected to a push rod 702, and the other end of each push rod 702 extends into a sliding groove 604 and slides in contact with a turntable 603. The turntable 603 drives the push rod 702 to move through the sliding groove 604, and the push rod 702 drives the cutter 701 to move, ensuring that the distance between the cutter 701 and the transmission line is appropriate. This avoids the situation where the distance between the cutter 701 and the transmission line is too large, making it impossible for the cutter 701 to cut hard foreign objects wrapped around the transmission line, and the distance between the cutter 701 and the transmission line is too small, causing the cutter 701 to damage the transmission line.

[0032] Please see Figure 1-2The driving mechanism 4 includes a driving motor 401, which is fixedly connected to the support plate 101. A driving shaft 402 is fixedly connected to one side of the driving motor 401, and the other end of the driving shaft 402 extends into the outer cylinder 201. A driving bevel gear 403 is fixedly connected to the driving shaft 402. The driving bevel gear 403 is located in the outer cylinder 201 and meshes with the transmission bevel gear 304. When the driving motor 401 is started, it controls the driving shaft 402 to rotate. The driving shaft 402 drives the inner cylinder 301 to rotate through the driving bevel gear 403 and the transmission bevel gear 304. That is, the inner cylinder 301 drives several rotating shafts 501 to revolve.

[0033] The working principle of this invention is as follows: When the device is in use, the power transmission line passes through the inner cylinder 301. A spring 504 acts on one end of the turntable 603, causing the turntable 603 to move via the adhesive layer 605, which in turn moves the adhesive plate 606 and the cleaning brush 607. This ensures that the cleaning brush 607 is in close contact with the surface of the power transmission line. Simultaneously, during the movement of the turntable 603, the turntable 603 moves the push rod 702 via the sliding groove 604. The push rod 702 then moves the cutter 701, ensuring that the distance between the cutter 701 and the power transmission line is appropriate and preventing brittle fractures between the cutter 701 and the power transmission line. If the distance between the cutter 701 and the power line is too large, the cutter 701 will be unable to cut the hard foreign objects entangled in the power line. If the distance between the cutter 701 and the power line is too small, the cutter 701 will damage the power line. Then, the drone moves the support plate 101 and the connecting plate 102 through the connecting bolt 103. The connecting plate 102 then moves the inner cylinder 301 through the outer cylinder 201, the limit rod 202, the ball bearing 203, and the slot 302. The inner cylinder 301 moves the cutter 701 through the guide groove 303 to cut the hard foreign objects entangled in the power line. At the same time, the drive motor 401 starts. The drive motor 401 controls the drive shaft 402 to rotate. The drive shaft 402 drives the inner cylinder 301 to rotate via the drive bevel gear 403 and the transmission bevel gear 304. That is, the inner cylinder 301 drives several rotating shafts 501 to revolve. At the same time, the several rotating shafts 501 and several connecting rods 601 drive the turntable 603 to revolve. That is, the turntable 603 drives the cleaning brush 607 to rotate via the adhesive layer 605 and the adhesive plate 606 to clean the soft foreign matter adhering to the surface of the transmission line. At the same time, during the revolution of the several rotating shafts 501, the driven bevel gear 502 meshes with the ring bevel gear 204. The driven bevel gear 502 rotates under the action of the ring bevel gear 204 during its movement. The driven bevel gear 502 then drives the rotating shaft 501 to rotate. The rotating shaft 501 drives the connecting rod 601 to rotate through the guide block 602. The connecting rod 601 drives the cleaning brush 607 to rotate through the turntable 603, the adhesive layer 605, and the adhesive plate 606, thereby improving the cleaning effect of the cleaning brush 607. At the same time, the cleaning brush 607 is bonded to the slide groove 604 through the adhesive plate 606 and the adhesive layer 605, which makes it easy to remove the cleaning brush 607 for cleaning after the surface of the power transmission line is cleaned.
