Description

Technical Field

[0001] This invention relates to a foreign object removal device for power transmission lines, belonging to the field of power transmission line engineering technology. Background Technology

[0002] With the rapid development of the power grid and the increasing demands of staff for power supply reliability, the safety and reliability of power grid operation have become more important. When foreign objects are suspended on the transmission line conductors, failure to handle them in a timely manner will inevitably affect the safe operation of the power grid and may even cause line tripping faults. Therefore, the timeliness of handling foreign objects on live conductors directly affects the safe operation of the power grid.

[0003] Overhead transmission lines are often located in the field. During years of operation, changes in the surrounding environment can lead to the presence of floating foreign objects. These objects, such as plastic strips, shredded wires, and threads, can be blown up by the wind and become suspended on the transmission lines. Existing foreign object removal devices for transmission lines generally use hooks or have workers ride in a tractor to remove them. Using hooks to drag and pull is not effective at removing tightly wrapped plastic strips, and it is time-consuming and labor-intensive. Using tractors is even more manpower and resources-intensive, and there are certain dangers in the removal process, which is not conducive to the rapid removal of foreign objects.

[0004] A method of using a telescopic charged foreign object removal device is disclosed in Chinese invention patent publication number CN114744547A. The telescopic charged foreign object removal device includes an operating rod assembly and a transmission mechanism, wherein the transmission mechanism is installed inside the operating rod assembly.

[0005] The above-mentioned reference example adopts a disassembled and assembled insulated operating rod structure. Not only can the length of the device be adjusted according to the working environment, but it also meets the requirements of live operation without the need for power outage operation. However, it requires workers to lift it for cleaning, which puts a heavy workload on the workers. If they need to work for a long time, it will not only cause harm to the workers' health, but also affect the cleaning efficiency. Therefore, it is urgent to improve it. Summary of the Invention

[0006] In order to overcome the shortcomings of existing methods for cleaning transmission lines, such as being time-consuming, labor-intensive, and inefficient, this invention designs a foreign object removal device for transmission lines. This device eliminates the need for manual removal using a trolley or hook, greatly reducing the workload of cleaning transmission lines. It is also relatively safe and reliable, and facilitates the rapid removal of foreign objects.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A foreign object removal device for power transmission lines includes a lifting support rod. A height adjustment component is installed at the top of the lifting support rod, and a foreign object removal bracket is slidably mounted on the height adjustment component. A drive roller for moving along the direction of the power line and a foreign object removal component for cleaning foreign objects on the power line are respectively installed on one side of the top of the foreign object removal bracket. A drive component for driving the drive roller to move along the direction of the power line and for driving the foreign object removal component to clean foreign objects is also installed at the top of the foreign object removal bracket.

[0009] Furthermore, the drive assembly includes a side transmission chamber, a top transmission chamber, an outer drive chamber, a transmission component, and a drive motor. One end of the top transmission chamber is fixedly connected to the top side of the foreign object removal bracket, and the other end is fixedly connected to the side transmission chamber. The outer drive chamber is fixedly disposed at the front end of the top transmission chamber. The drive roller is rotatably connected between the side transmission chamber and the foreign object removal bracket. The foreign object removal component is disposed at the bottom of the free end of the outer drive chamber. The side transmission chamber, the top transmission chamber, and the outer drive chamber are all hollow and each contains a transmission component. The output end of the drive motor is connected to the drive roller and the foreign object removal component respectively through the transmission component.

[0010] Furthermore, the transmission assembly includes a side transmission rod, a top transmission rod, a middle transmission rod, and a cutting drive rod. The side transmission rod is rotatably mounted inside the side transmission compartment, the top transmission rod is rotatably mounted inside the top transmission compartment, and the middle transmission rod is rotatably mounted inside the outer drive compartment. The side transmission rod is connected to the drive roller, the drive motor, and the top transmission rod, respectively. The top transmission rod is connected to the middle transmission rod, the middle transmission rod is connected to the cutting drive rod, and the cutting drive rod is connected to the foreign object removal assembly.

[0011] Furthermore, the height adjustment assembly includes a support connecting plate, which is fixed to the top of the lifting support rod. The support connecting plate has an adjustment socket that runs vertically through it. The side of the support connecting plate has a fixing screw hole that communicates with the adjustment socket. A fixing screw is rotatably threaded into the fixing screw hole. An abutment connecting plate is rotatably connected to the end of the fixing screw. The abutment connecting plate is disposed in the adjustment socket and fits against the side wall of the foreign object removal bracket.

[0012] Furthermore, the end of the top transmission rod rotates and enters the side transmission compartment, and the end of the top transmission rod meshes with the bevel gear fixedly sleeved on the side transmission rod through a fixedly sleeved bevel gear.

[0013] Furthermore, one end of the middle transmission rod engages with a bevel gear fixedly mounted on the top transmission rod via a fixedly mounted bevel gear, and the other end of the middle transmission rod engages with a bevel gear fixedly mounted on the cutting drive rod via a fixedly mounted bevel gear.

[0014] Furthermore, the foreign object removal assembly includes a cutting drive rod, the top end of which rotates and passes into the outer drive chamber and is connected to the cutting drive rod. The bottom end of the cutting drive rod extends out of the outer drive chamber and is fitted with several cutting fixing sleeves at even intervals from top to bottom. Several foreign object cutting blades are evenly arranged on the side of the cutting fixing sleeves along the circumference.

[0015] Furthermore, a stabilizing sleeve is fixedly installed at the bottom of the outer drive chamber. The bottom end of the cutting transmission rod rotates out of the stabilizing sleeve, and the top end of the cutting transmission rod rotates into the outer drive chamber. The top end of the cutting transmission rod meshes with a bevel gear fixedly installed on the body of the cutting drive rod through a fixedly installed bevel gear.

[0016] Furthermore, the side of the contact connecting plate closest to the foreign object removal bracket is provided with anti-slip texture.

[0017] Furthermore, the outer end of the fixing screw is provided with a rotating handle, and the rotating handle is provided with an anti-slip pad.

[0018] Compared with the prior art, the present invention has the following features and beneficial effects:

[0019] 1. This invention allows for adjustment of the required cleaning height by setting up a lifting support rod, a height adjustment component, and a foreign object removal bracket, thus making it suitable for cleaning lines at different heights and highly adaptable. Furthermore, the inclusion of drive rollers facilitates the overall sliding and hoisting of the device onto the line, significantly reducing the workload for workers. To further simplify line cleaning, a foreign object removal component is included. The drive component, by rotating the drive rollers along the line, simultaneously drives the foreign object removal component to remove foreign objects from the line, further reducing the workload for workers and greatly improving the efficiency of cleaning foreign objects from the line.

[0020] 2. In this invention, the drive motor drives the drive roller and the foreign object removal component to move synchronously through the transmission component. That is, foreign objects on the line are cleaned while moving, thereby further improving work efficiency. The U-shaped frame is formed by the structure of the side transmission chamber, the top transmission chamber and the foreign object removal bracket, and the drive roller is placed between the side transmission chamber and the foreign object removal bracket, so that the foreign object removal bracket can be stably hooked on the line, which facilitates cleaning. The outer drive chamber is located at the front end of the top transmission chamber, so that the drive roller and the foreign object removal component can be arranged on the same straight line, which facilitates cleaning during sliding.

[0021] 3. This invention eliminates the need for manual pulling. During the movement of the foreign object removal component by the drive roller, the high-speed rotation of the foreign object cutting blades on the component can cut and break up the plastic ribbons or filaments wrapped around the power transmission line, thus effectively and quickly removing foreign objects from the power transmission line. It also eliminates the need for manual removal using a trolley or hook, greatly reducing the workload of cleaning power transmission lines. Furthermore, it is relatively safe and reliable, facilitating the rapid removal of foreign objects. Attached Figure Description

[0028] The present invention will now be described in more detail with reference to the embodiments.

[0029] like Figures 1 to 5 As shown, a foreign object removal device for power transmission lines includes a lifting support rod 1. A height adjustment component 2 is installed at the top of the lifting support rod 1. A foreign object removal bracket 3 is slidably installed on the height adjustment component 2. A drive roller 5 for moving along the line setting direction and a foreign object removal component 6 for cleaning foreign objects on the line are respectively installed on one side of the top of the foreign object removal bracket 3. A drive component is also installed at the top of the foreign object removal bracket 3 to drive the drive roller 5 to move along the line setting direction and to drive the foreign object removal component 6 to clean foreign objects.

[0030] As can be seen from the above description, the beneficial effects of the present invention are as follows: by setting the lifting support rod 1, the height adjustment component 2, and the foreign object removal bracket 3, the required cleaning height can be adjusted, thus making it suitable for cleaning lines at different heights and having strong applicability. At the same time, by setting the drive roller 5, it is convenient to slide and hoist the entire device onto the line, thereby greatly reducing the workload of the workers. In order to make it easier to clean the line, the foreign object removal component 6 is set. At the same time, by setting the drive component, the drive component drives the drive roller 5 to roll along the line, while driving the foreign object removal component 6 to clean the foreign objects on the line, further reducing the workload of the workers and greatly improving the efficiency of cleaning foreign objects on the line.

[0031] Furthermore, the drive assembly includes a side drive chamber 601, a top drive chamber 605, an outer drive chamber 607, a transmission component, and a drive motor 604. One end of the top drive chamber 605 is fixedly connected to the top side of the foreign object removal bracket 3, and the other end is fixedly connected to the side drive chamber 601. The outer drive chamber 607 is fixedly disposed at the front end of the top drive chamber 605. The drive roller 5 is rotatably connected between the side drive chamber 601 and the foreign object removal bracket 3. The foreign object removal component 6 is disposed at the bottom of the free end of the outer drive chamber 607. The side drive chamber 601, the top drive chamber 605, and the outer drive chamber 607 are all hollow and each has a transmission component inside. The output end of the drive motor 604 is connected to the drive roller 5 and the foreign object removal component 6 respectively through the transmission component.

[0032] As described above, the drive motor 604 drives the drive roller 5 and the foreign object removal component 6 to move synchronously through the transmission assembly. This means that foreign objects on the line are cleaned up while the roller is moving, thereby further improving work efficiency. The U-shaped frame is formed by the side transmission chamber 601, the top transmission chamber 605, and the foreign object removal bracket 3, and the drive roller 5 is placed between the side transmission chamber 601 and the foreign object removal bracket 3. This allows the foreign object removal bracket 3 to be stably hooked onto the line, facilitating cleaning. The outer drive chamber 607 is located at the front end of the top transmission chamber 605, so that the drive roller 5 and the foreign object removal component 6 can be aligned on the same straight line, facilitating cleaning during sliding.

[0033] Furthermore, the transmission assembly includes a side transmission rod 602, a top transmission rod 606, a middle transmission rod 608, and a cutting drive rod 609. The side transmission rod 602 is rotatably mounted inside the side transmission chamber 601, the top transmission rod 606 is rotatably mounted inside the top transmission chamber 605, and the middle transmission rod 608 is rotatably mounted inside the outer drive chamber 607. The side transmission rod 602 is connected to the drive roller 5, the drive motor 604, and the top transmission rod 606 respectively. The top transmission rod 606 is connected to the middle transmission rod 608, the middle transmission rod 608 is connected to the cutting drive rod 609, and the cutting drive rod 609 is connected to the foreign object removal assembly 6.

[0034] As described above, the side transmission rod 602 is rotated by the drive motor 604. Since the side transmission rod 602 is also connected to the drive roller 5 and the top transmission rod 606, the rotation of the side transmission rod 602 drives the drive roller 5 and the top transmission rod 606 to rotate. The top transmission rod 606 is connected to the middle transmission rod 608, which in turn drives the middle transmission rod 608 to rotate. The middle transmission rod 608 is connected to the cutting transmission rod 611, which in turn drives the cutting transmission rod 611 to rotate. This causes the cutting transmission rod 611 to drive the foreign object removal component 6 to rotate, thereby removing foreign objects. By setting the transmission component, the output direction of the drive motor 604 can be changed, making it suitable for removing foreign objects from circuits and suitable for promotion and use.

[0035] Furthermore, the height adjustment component 2 includes a support connecting plate 201, which is fixed to the top of the lifting support rod 1. An adjustment socket 202 is provided through the upper and lower parts of the support connecting plate 201. A fixing screw hole 203 communicating with the adjustment socket 202 is provided on the side of the support connecting plate 201. A fixing screw 204 is rotatably threaded into the fixing screw hole 203. An abutting connecting plate 205 is rotatably connected to the end of the fixing screw 204. The abutting connecting plate 205 is disposed in the adjustment socket 202 and is fitted against the side wall of the foreign object removal bracket 3.

[0036] As can be seen from the above description, the foreign object removal bracket 3 is slidably sleeved in the adjustment socket 202, and the static friction between the contact connecting plate 205 and the foreign object removal bracket 3 is adjusted by rotating the fixing screw 204, thereby realizing the height position adjustment of the foreign object removal bracket 3. The adjustment is convenient and quick and suitable for different working environments.

[0037] Furthermore, the end of the top transmission rod 606 rotates and enters the side transmission compartment 601, and the end of the top transmission rod 606 engages with the bevel gear fixedly sleeved on the side transmission rod 602 through a fixedly sleeved bevel gear.

[0038] As can be seen from the above description, bevel gear meshing transmission has high transmission efficiency, high transmission accuracy, strong load-bearing capacity and good durability, making it suitable for promotion and use.

[0039] Furthermore, one end of the middle transmission rod 608 engages with a bevel gear fixedly mounted on the top transmission rod 606 via a fixedly mounted bevel gear, and the other end of the middle transmission rod 608 engages with a bevel gear fixedly mounted on the cutting drive rod 609 via a fixedly mounted bevel gear.

[0040] As can be seen from the above description, bevel gear meshing transmission has high transmission efficiency, high transmission accuracy, strong load-bearing capacity and good durability, making it suitable for promotion and use.

[0041] Furthermore, the foreign object removal assembly 6 includes a cutting transmission rod 611. The top end of the cutting transmission rod 611 rotates and passes into the outer drive chamber 607 and is connected to the cutting drive rod 609. The bottom end of the cutting transmission rod 611 extends out of the outer drive chamber 607 and is uniformly fitted with several cutting fixing sleeves 612 from top to bottom. Several foreign object cutting blades 613 are uniformly arranged on the side of the cutting fixing sleeves 612 along the circumference.

[0042] As can be seen from the above description, the cutting transmission rod 611 rotates to drive the cutting fixing sleeve 612 to rotate, which in turn drives the foreign object cutting blade 613 to rotate to cut and clean the foreign object. This method is highly efficient and suitable for promotion and use.

[0043] Furthermore, a stabilizing sleeve 610 is fixedly installed at the bottom of the outer drive chamber 607. The bottom end of the cutting transmission rod 611 rotates out of the stabilizing sleeve 610, and the top end of the cutting transmission rod 611 rotates into the outer drive chamber 607. The top end of the cutting transmission rod 611 meshes with a bevel gear fixedly installed on the body of the cutting drive rod 609 through a fixedly installed bevel gear.

[0044] As can be seen from the above description, the connection stability of the cutting transmission rod 611 can be guaranteed by setting the stabilizing sleeve 610, ensuring that the operation can proceed smoothly.

[0045] Furthermore, the side of the contact plate 205 near the foreign object removal bracket 3 is provided with anti-slip texture.

[0046] As can be seen from the above description, the anti-slip texture can further improve the static friction between the contact connecting plate 205 and the foreign object removal bracket 3, and further improve the stability of the device.

[0047] Furthermore, a rotating handle is provided at the outer end of the fixing screw 204, and an anti-slip pad is provided on the rotating handle.

[0048] As can be seen from the above description, the rotating handle facilitates the rotation of the fixing screw 204, thereby facilitating the adjustment of the static friction between the contact connecting plate 205 and the foreign matter removal bracket 3.

[0049] Example 1

[0050] Please see Figures 1 to 4 A foreign object removal device for power transmission lines includes a lifting support rod 1, a height adjustment component 2 installed at the top of the lifting support rod 1, a foreign object removal bracket 3 slidably mounted on the height adjustment component 2, a drive roller 5 for moving along the line setting direction and a foreign object removal component 6 for cleaning foreign objects on the line respectively installed on one side of the top of the foreign object removal bracket 3, and a drive component for driving the drive roller 5 to move along the line setting direction and for driving the foreign object removal component 6 to clean foreign objects.

[0051] Furthermore, the drive assembly includes a side drive chamber 601, a top drive chamber 605, an outer drive chamber 607, a transmission component, and a drive motor 604. One end of the top drive chamber 605 is fixedly connected to the top side of the foreign object removal bracket 3, and the other end is fixedly connected to the side drive chamber 601. The outer drive chamber 607 is fixedly disposed at the front end of the top drive chamber 605. The drive roller 5 is rotatably connected between the side drive chamber 601 and the foreign object removal bracket 3. The foreign object removal component 6 is disposed at the bottom of the free end of the outer drive chamber 607. The side drive chamber 601, the top drive chamber 605, and the outer drive chamber 607 are all hollow and each has a transmission component inside. The output end of the drive motor 604 is connected to the drive roller 5 and the foreign object removal component 6 respectively through the transmission component.

[0052] In this embodiment, a rotating connecting frame 4 is provided between the side transmission chamber 601 and the foreign object removal bracket 3. The rotating connecting frame 4 is inverted U-shaped. The drive roller 5 is located in the U-shaped groove of the rotating connecting frame 4 and is rotatably connected to the rotating connecting frame 4 through the drive connecting rod 603. One end of the drive connecting rod 603 rotates through the side wall of the rotating connecting frame 4 and the side transmission chamber 601 in sequence and then engages with the bevel gear on the side transmission rod 602 through bevel gear transmission.

[0053] Furthermore, the side drive rod 602 is rotatably mounted inside the side drive compartment 601, the top drive rod 606 is rotatably mounted inside the top drive compartment 605, and the middle drive rod 608 is rotatably mounted inside the outer drive compartment 607. The side drive rod 602 is connected to the drive roller 5, the drive motor 604, and the top drive rod 606 respectively. The top drive rod 606 is connected to the middle drive rod 608. The middle drive rod 608 is connected to the cutting drive rod 609. The cutting drive rod 609 is connected to the foreign object removal assembly 6.

[0054] Furthermore, the end of the top transmission rod 606 rotates and enters the side transmission compartment 601, and the end of the top transmission rod 606 engages with the bevel gear fixedly sleeved on the side transmission rod 602 through a fixedly sleeved bevel gear.

[0055] Furthermore, one end of the middle transmission rod 608 engages with a bevel gear fixedly mounted on the top transmission rod 606 via a fixedly mounted bevel gear, and the other end of the middle transmission rod 608 engages with a bevel gear fixedly mounted on the cutting drive rod 609 via a fixedly mounted bevel gear.

[0056] Furthermore, the foreign object removal assembly 6 includes a cutting transmission rod 611. The top end of the cutting transmission rod 611 rotates and passes into the outer drive chamber 607 and is connected to the cutting drive rod 609. The bottom end of the cutting transmission rod 611 extends out of the outer drive chamber 607 and is uniformly fitted with several cutting fixing sleeves 612 from top to bottom. Several foreign object cutting blades 613 are uniformly arranged on the side of the cutting fixing sleeves 612 along the circumference.

[0057] Furthermore, a stabilizing sleeve 610 is fixedly installed at the bottom of the outer drive chamber 607. The bottom end of the cutting transmission rod 611 rotates out of the stabilizing sleeve 610, and the top end of the cutting transmission rod 611 rotates into the outer drive chamber 607. The top end of the cutting transmission rod 611 meshes with a bevel gear fixedly installed on the body of the cutting drive rod 609 through a fixedly installed bevel gear.

[0058] In this embodiment, existing foreign object removal devices for power transmission lines generally use hooks or workers riding in a tractor to remove them. Using hooks to drag and pull is not easy to remove tightly wrapped plastic ribbons, which is time-consuming and labor-intensive. Using a tractor is even more manpower and material-intensive, and there are certain dangers in the removal process, which is not conducive to the rapid removal of foreign objects.

[0059] In this embodiment, the drive roller 5, which is engaged with the power transmission line, can move gradually under the drive of the drive motor 604, without the need for manual pulling. As the drive roller 5 moves the foreign object removal component 6, the foreign object cutting blade 613 on the foreign object removal component 6 can cut and break the plastic ribbons or filaments wrapped around the power transmission line under the high-speed rotation, thereby effectively and quickly removing foreign objects from the power transmission line. It also eliminates the need for manual removal using a flyer or hook, greatly reducing the workload of cleaning the power transmission line. Furthermore, it is relatively safe and reliable, and facilitates the rapid removal of foreign objects.

[0060] Example 2

[0061] A foreign object removal device for power transmission lines, based on the above-described embodiment one, further defines the overall mechanical connection relationship of the height adjustment component 2 as follows:

[0062] Please see Figure 1 , Figure 2 and Figure 5 The height adjustment component 2 includes a support connecting plate 201, which is fixed to the top of the lifting support rod 1. An adjustment socket 202 is provided through the upper and lower parts of the support connecting plate 201. A fixing screw hole 203 communicating with the adjustment socket 202 is provided on the side of the support connecting plate 201. A fixing screw 204 is rotatably threaded into the fixing screw hole 203. An abutting connecting plate 205 is rotatably connected to the end of the fixing screw 204. The abutting connecting plate 205 is set in the adjustment socket 202 and is set against the side wall of the foreign object removal bracket 3.

[0063] Furthermore, the side of the contact plate 205 near the foreign object removal bracket 3 is provided with anti-slip texture.

[0064] Furthermore, a rotating handle is provided at the outer end of the fixing screw 204, and an anti-slip pad is provided on the rotating handle.

[0065] In this example, a rubber pad is provided on the outer side of the drive roller 5 to increase the friction with the power transmission line.

[0066] In this example, since different lines have different heights, in order to better adapt to power transmission lines of different heights, the height of the foreign object removal bracket 3 is adjusted by setting the height adjustment component 2, which further improves the applicability of this device.

[0067] The working principle of this invention is as follows: In specific operation, the operator first adjusts the foreign object removal bracket 3 slidably inserted on the height adjustment component 2, so that the drive roller 5 on the side of the foreign object removal bracket 3 can engage with the power transmission line and roll on the power transmission line. Then, by starting the drive motor 604, the drive motor 604 can drive the side transmission rod 602 to rotate. The side transmission rod 602 drives the cutting drive rod 609 to rotate through the top transmission rod 606, which in turn drives the cutting drive rod 611. This causes the several foreign object cutting blades 613 on the cutting drive rod 611 to rotate at high speed. The foreign object cutting blades 613 are located at the front end of the drive roller 5 rolling on the power transmission line. As the drive roller 5 moves on the power transmission line, the foreign object cutting blades 613 cut and break the plastic ribbons or filaments wrapped on the power transmission line, thereby quickly removing the foreign objects from the power transmission line.
