[0002] With the rapid development of the power grid and the continuous improvement of the requirements of staff for power supply reliability, the safety and reliability of power grid operation become more important. When there are foreign objects hanging on the transmission line conductors, if they cannot be processed in a timely and rapid manner, it will inevitably affect the safe operation of the power grid and even cause line tripping faults. Therefore, the timeliness of handling foreign objects on the conductors directly affects the safe operation of the power grid.

[0003] Overhead transmission lines are often set in the wild. During the long-term operation process, the surrounding environment changes and there are floating foreign objects. It is easy for floating objects such as plastic strips, scraps of cloth, and silk threads to be blown up by the wind and hang on the transmission lines. For the existing foreign object cleaning devices for transmission lines, generally, hooks are used or workers take a flying car to go to remove them. Using the method of dragging and pulling with a hook, it is not easy to remove the tightly wound plastic floating ribbons, which is time-consuming and laborious. And using a flying car is even more labor-intensive and material-consuming, and there is a certain danger during the removal process, which is not conducive to the rapid removal of foreign objects. Therefore, we propose a foreign object removal device for transmission lines to solve the above problems. Summary of the Invention

Specific embodiments

[0016] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0017] The present application provides a device for removing foreign objects from a transmission line, mainly used to solve the problems of existing devices for removing foreign objects from a transmission line. Generally, a hook or a staff member takes a flying vehicle to remove them. Using the method of dragging and pulling with a hook, it is not easy to remove tightly wound plastic streamers, which is time-consuming and laborious. Using a flying vehicle is even more costly in terms of manpower and material resources, and there are certain risks during the removal process. The following technical solutions are provided and will be described in detail below in conjunction with Figures 1-5 for a detailed description: A device for removing foreign objects from a transmission line includes: A mounting plate 1, at the bottom of one side of which is fixedly provided with a wind hood 2, and at the bottom of the wind hood 2 is fixedly provided with a U-shaped plate 3; A support rod 4, arranged at the bottom of the U-shaped plate 3, and the length of the support rod 4 is adjustable; A cutting mechanism 5, used for cutting foreign objects. The cutting mechanism 5 includes a mounting box 501 fixedly provided in the middle of one side of the mounting plate 1. There are through holes at the top and bottom of the mounting box 501, and a movable plate 502 is slidably inserted through the through holes. On one side of the movable plate 502 outside the mounting box 501, cutting blades 503 are fixedly provided at equal intervals; A telescopic mechanism 6, arranged inside the mounting box 501, used to adjust the distance that the movable plate 502 extends out of the through hole; Traveling wheels 7, arranged on both sides of the cutting mechanism 5, used to drive the mounting plate 1 to move on the transmission line. The traveling wheels 7 include L-shaped plates 701 fixedly provided on both sides of the mounting box 501, and a driving wheel 702 is rotatably connected between the L-shaped plates 701 and the mounting plate 1 through a rotating shaft.

[0018] The specific implementation steps and principle explanations of the device for removing foreign objects from a transmission line: First step, move the device to the position on the transmission line where foreign objects need to be removed. By adjusting the length of the support rod 4, the transmission line is embedded in the wheel groove (upper or lower) of the driving wheel 702. Second step, according to the size and position of the foreign object, adjust the distance that the movable plate 502 protrudes out of the through hole through the telescopic mechanism 6 to ensure the cutting effect. Third step, use the walking wheel 7 to drive the mounting plate 1 to reciprocate on the transmission line. During the movement, the cutting blade 503 can cut the foreign objects on the transmission line, so as to achieve the purpose of removing the foreign objects.

[0019] The foreign object removal device for the transmission line combines the cutting mechanism 5 and the walking wheel 7, which can quickly remove the foreign objects hanging on the transmission line and improve the removal efficiency. The setting of the telescopic mechanism 6 can be adjusted according to the size and position of the foreign object to ensure the cutting effect. The support rod 4 is composed of several short rods 401 spliced together, and the length can be adjusted according to needs to adapt to different working scenarios. In summary, the foreign object removal device for the transmission line has the advantages of high efficiency, flexibility, safety, multi-function and reliability through the combined design of the mounting plate 1, the support rod 4, the cutting mechanism 5, the telescopic mechanism 6 and the walking wheel 7, and can effectively solve the problem of foreign object cleaning on the transmission line and improve the safety and reliability of the power grid operation.

[0020] As Figure 1 shown, in some embodiments, hook rakes 8 are fixedly arranged at equal intervals on the top of the mounting plate 1. More specifically, the design of the hook rakes 8 can increase the function and flexibility of the device. By using multiple curved metal hooks, the hook rakes 8 can effectively grab and pull larger foreign objects wound on the transmission line, such as branches, kites or other sundries. This design can improve the removal efficiency and reduce the time and labor intensity of manual cleaning.

[0021] As Figure 4 shown, in some embodiments, a blower 9 is installed inside the C-shaped plate 3. The blower 9 generates a strong air flow by forcing the air to flow and discharge, and blows the foreign objects off the transmission line. In order to improve the utilization efficiency of the wind force and ensure that the wind force can be accurately transmitted to the target area, the air outlet end of the blower 9 is connected to the bottom of the wind hood 2. By connecting the air outlet end of the blower 9 to the bottom of the wind hood 2, the wind force can be concentrated in a specific direction, so as to ensure that the air flow generated by the blower 9 is guided to the target area on the transmission line, increasing the impact force and removal effect on the foreign objects. This connection method can make the air flow of the blower 9 more targeted and efficient, ensuring the accuracy and efficiency of the cleaning process.

[0022] As Figure 4As shown, in some embodiments, a retaining net 201 is provided at the top of the wind hood 2. More specifically, a retaining net 201 is provided at the top of the wind hood 2 to prevent foreign objects from entering the interior of the wind hood 2 from above. The design of the retaining net 201 can effectively prevent foreign objects that may fall or float in from above from entering the interior of the wind hood 2, thereby protecting the device and ensuring the smooth progress of the cleaning process.

[0023] As Figure 5 shown, in some embodiments, the cutting blade 503 is triangular pyramidal, and an arc-shaped notch is formed in the middle of its top. More specifically, the cutting blade 503 is designed in a triangular pyramidal shape, having a larger cutting area and being able to cut thicker materials or handle larger objects more effectively. The triangular pyramidal blade can provide a wider contact area during use, increasing the cutting force and cutting efficiency, enabling it to handle larger-sized objects or thicker materials. The design of the arc-shaped notch enables the cutting blade 503 to better adapt to the shape of the transmission line, increasing the contact area with foreign objects and thus enhancing the cleaning effect.

[0024] As Figure 5 shown, in some embodiments, the telescopic mechanism 6 includes a rotating rod 601 rotatably connected between the inner side walls of the mounting box 501. Threads with opposite spiral directions are formed on both sides of the rotating rod 601, and movable blocks 602 are symmetrically threadedly connected thereto. Hinge plates 603 are hinged to both sides of the movable block 602, and one end of the hinge plate 603 away from the movable block 602 is hinged to the movable plate 502. A driving member for driving the rotating rod 601 to rotate is provided in the middle of the mounting box 501. More specifically, when the driving member drives the rotating rod 601 to rotate, the movable blocks 602 on both sides will move in opposite directions, thereby changing the angle between the hinge plate 603 and the movable plate 502, and further changing the distance that the movable plate extends out of the through hole, ensuring the cutting effect of the cutting blade 503.

[0025] As Figure 5 shown, in some embodiments, the driving member includes a worm 604 rotatably connected in the middle of the interior of the mounting box 501. A worm gear 605 is fixedly provided in the middle of the rotating rod 601, and the worm gear 605 meshes with the worm 604. More specifically, by rotating the worm 604, the worm gear 605 can be driven to rotate, thereby realizing the rotation of the rotating rod 601.

[0026] As Figure 4As shown, in some embodiments, the support rod 4 is composed of a plurality of short rods 401 spliced together. One end of the short rod 401 is fixedly provided with a connection head 402, and the other end is provided with a connection groove 403 that is threadedly engaged with the connection head 402. The bottom of the U-shaped plate 3 is fixedly provided with a connection cylinder 301, and the connection head 402 can be threadedly connected to the connection cylinder 301. More specifically, the support rod 4 is composed of a plurality of short rods 401 spliced together. This design can achieve the length adjustment of the support rod 4. One end of each short rod 401 is fixedly provided with a connection head 402, and the other end is provided with a connection groove 403 that is threadedly engaged with the connection head 402. Such a design enables the short rods 401 to be detachably connected through the threaded connection of the connection head 402 and the cooperation of the connection groove 403. This design has flexibility and adjustability, and the length can be adjusted and fixed according to actual needs. At the same time, due to the detachable connection between the short rods 401, it also facilitates the assembly and disassembly of the support rod 4.

[0027] As Figure 4 shown, in some embodiments, the short rod 401 is an insulating plastic rod, and a protective sleeve 404 is sleeved on one end thereof. More specifically, the short rod 401 is an insulating plastic rod. This design can provide good insulation performance and ensure the safety of the support rod 4 during use. The insulating plastic rod is usually made of a specific plastic material and has excellent insulation performance and corrosion resistance, which can effectively prevent current leakage and electric shock accidents. In addition, a protective sleeve 404 is sleeved on one end of the short rod 401. This design can provide additional protection. The protective sleeve 404 is usually made of wear-resistant and corrosion-resistant materials, which can effectively prevent the short rod 401 from being affected by external physical damage or chemical corrosion. At the same time, the protective sleeve 404 can also provide a better grip and facilitate the user to operate.

[0028] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
