[0002] In the power system, the overhead transmission line is an important component. However, there are often obstacles in the line. Common obstacles include branches, weeds, and other items. These obstacles may affect the stability and safety of the transmission line. During the cleaning process, special attention should be paid to protecting the structure and safety of the transmission line from damage.

[0003] The existing cleaning mainly relies on manual labor and drones. When using drones, the fan blades are prone to cutting the line, causing damage to the line. When cleaning manually, the obstacle clearance device needs to be held high. If the device is heavy, it cannot operate for a long time, and it is not convenient to apply force. Therefore, this application provides a transmission line obstacle clearance device to meet the requirements. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a transmission line obstacle clearance device to solve the problems that the existing cleaning mainly relies on manual labor and drones, the fan blades of the drones are prone to cutting the line during use, causing damage to the line, and when cleaning manually, the obstacle clearance device needs to be held high. If the device is heavy, it cannot operate for a long time, and it is not convenient to apply force.

[0005] To solve the above technical problems, the utility model provides the following technical solutions:

[0006] A transmission line obstacle clearance device includes two symmetrically arranged obstacle clearance mechanisms. Each obstacle clearance mechanism includes a housing. First and second sealing plates are respectively and fixedly connected to two sides of the housing. The housing, the first sealing plate, and the second sealing plate are all semicircular in shape and are all provided with through holes for the transmission line to pass through in the middle. A groove is provided on the second sealing plate. A conical roller is arranged inside the housing. A first gear is fixedly connected to one side of the conical roller. A rack is meshed with the first gear. An installation block is fixedly connected to one inner wall of the housing. A second gear is rotatably connected to one side of the installation block. A third gear is fixedly connected to the side of the second gear away from the installation block. The third gear is meshed with the rack. A fourth gear is rotatably connected to one inner wall of the housing where the housing is fixedly connected to the installation block. The second gear is meshed with the fourth gear. The rotating shaft of the fourth gear penetrates through the second sealing plate and is fixedly connected to a second cutting knife.

[0007] Preferably, a fifth gear is fixedly connected to the outer surface of the rotating shaft of the fourth gear inside the groove. Sawteeth are provided at the bottom of the groove on the second sealing plate. The sawteeth are meshed with the fifth gear.

[0008] Preferably, a telescopic rod is fixedly connected to the inner wall of the housing. One end of the telescopic rod away from the inner wall of the housing is fixedly connected to a mounting frame, and the mounting frame is rotatably connected to the conical roller.

[0009] Preferably, a spring for rebounding the mounting frame is sleeved on the telescopic rod.

[0010] Preferably, a rotating rod is fixedly connected to the side of the conical roller away from the first gear. After passing through the housing, the rotating rod is fixedly connected to a first cutting knife.

[0011] Preferably, a plurality of connecting plates are fixedly connected to the side of the housing, and the housing can be connected to another housing through the connecting plates and bolts.

[0012] Compared with the prior art, the utility model has at least the following beneficial effects:

[0013] In the above solution, by setting the conical roller, the first gear, the second gear, the third gear and the fourth gear, during use, the housings are symmetrically installed through the connecting plates, the circuit passes through the housing through the through hole, and the staff can install a motor (not marked in the figure) on the first gear in the housing. After installation, the motor is started to rotate the first gear, driving the conical roller to roll along the circuit, so that the housing moves on the circuit. When the first gear rotates, the third gear is driven to rotate through the rack transmission, so that the second gear also rotates accordingly, and then drives the fourth gear meshed with it to rotate, so that the second cutting knife rotates to cut the branches in front, removing the obstacles in front of the current circuit without damaging the circuit. There is no need for manual operation with the obstacle removal device held high, reducing the labor intensity and facilitating the operation of the staff.

[0014] By setting the fifth gear and the saw teeth, when the housing moves, the rotation of the fourth gear will drive the fifth gear to rotate by the rotating shaft in the groove of the second sealing plate. Since the fifth gear is meshed with the saw teeth, the second sealing plate, the housing and the first sealing plate rotate when the fifth gear rotates, and rotate along the circuit on the circuit. The advantage of this is that when the housing moves, it rotates itself to drive the second cutting knife to rotate around the circuit, expanding the range of removing obstacles in front of the circuit and better clearing the circuit of obstacles.

[0015] By setting the telescopic rod and the spring, when the two outer shells are installed on the line, the line squeezes the conical roller, causing the mounting bracket to approach the inner wall of the outer shell. The spring rebounds against the mounting bracket, keeping the conical roller always in contact with the line. The advantage of this is that it can adapt to more types of lines and clear obstacles on various different types of lines. By setting the first cutting knife, when the conical roller rotates, it can drive the rotating rod to rotate, causing the first cutting knife to also rotate and clear the obstacles on the side of the line. At the same time, when the outer shell rotates around the line, it will also drive the first cutting knife to rotate around the line, further expanding the clearing range of the first cutting knife and preventing branches from extending to the line from the side and causing harm.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The following will describe in detail a transmission line obstacle removal device provided by the present utility model in conjunction with the accompanying drawings and specific embodiments. At the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some well-known technologies, those skilled in the art can also adopt other alternative methods for implementation; moreover, the accompanying drawings are only for more specifically describing the embodiments and are not intended to specifically limit the present utility model.

[0025] As Figures 1-4 shown, an embodiment of the present utility model provides a transmission line obstacle removal device, which includes two symmetrically arranged obstacle removal mechanisms 1. The obstacle removal mechanism 1 includes a housing 2. First sealing plates 3 and second sealing plates 4 are respectively fixedly connected to both sides of the housing 2. The housing 2, the first sealing plate 3 and the second sealing plate 4 are all in a semicircular shape and are all provided with through holes 22 for the transmission line to pass through in the middle. A groove 5 is provided on the second sealing plate 4. A conical roller 11 is arranged inside the housing 2. A first gear 12 is fixedly connected to one side of the conical roller 11. A rack 13 is engaged with the first gear 12. A mounting block 14 is fixedly connected to one inner wall of the housing 2. A second gear 15 is rotatably connected to one side of the mounting block 14. A third gear 16 is fixedly connected to the side of the second gear 15 away from the mounting block 14. The third gear 16 is engaged with the rack 13. A fourth gear 17 is rotatably connected to the inner wall of the housing 2 on the side where the mounting block 14 is fixedly connected. The second gear 15 and the fourth gear 17 are engaged with each other. The rotating shaft of the fourth gear 17 penetrates through the second sealing plate 4 and is fixedly connected with a second cutting knife 19. A fifth gear 18 is fixedly connected to the outer surface of the rotating shaft of the fourth gear 17 inside the groove 5 on the second sealing plate 4. A sawtooth 20 is arranged at the bottom of the groove 5 on the second sealing plate 4. The sawtooth 20 is engaged with the fifth gear 18. A rotating rod 9 is fixedly connected to the side of the conical roller 11 away from the first gear 12. The rotating rod 9 penetrates through the housing 2 and is fixedly connected with a first cutting knife 10. A plurality of connecting plates 21 are fixedly connected to the side of the housing 2. The housing 2 can be connected to another housing 2 through the connecting plates 21 and bolts.

[0026] By setting the conical roller 11, the first gear 12, the second gear 15, the third gear 16 and the fourth gear 17, when in use, the housings 2 are symmetrically installed through the connecting plates 21, and the line passes through the through holes 22 and penetrates through the housings 2. The staff can install a motor (not shown in the figure) on the first gear 12 inside the housing 2. After installation, the motor is started to make the first gear 12 rotate, driving the conical roller 11 to roll along the line, so that the housing 2 moves on the line. When the first gear 12 rotates, the third gear 16 is driven to rotate through the rack 13, so that the second gear 15 also rotates accordingly, and then drives the engaged fourth gear 17 to rotate, making the second cutting knife 19 rotate to cut the branches in front, removing the obstacles in front of the current line without damaging the line, eliminating the need for manual operation with the obstacle removal device held high, reducing the labor intensity and facilitating the operation of the staff.

[0027] By setting the fifth gear 18 and the serrations 20, when the outer shell 2 moves, the rotation of the fourth gear 17 will cause the rotating shaft to drive the fifth gear 18 to rotate in the groove 5 of the second sealing plate 4. Since the fifth gear 18 meshes with the serrations 20, the rotation of the fifth gear 18 causes the second sealing plate 4, the outer shell 2, and the first sealing plate 3 to rotate, and rotate along the line on the line. The advantage of this is that when the outer shell 2 moves, its self-rotation drives the second cutting knife 19 to rotate around the line, expanding the range of clearing obstacles in front of the line and better clearing the line of obstacles.

[0028] Such as Figure 2 , Figure 3 and Figure 4 As shown, a telescopic rod 6 is fixedly connected to the inner wall of the outer shell 2. One end of the telescopic rod 6 away from the inner wall of the outer shell 2 is fixedly connected to a mounting bracket 8. The mounting bracket 8 is rotatably connected to a tapered roller 11. A spring 7 for rebounding the mounting bracket 8 is sleeved on the telescopic rod 6. One side of the tapered roller 11 away from the first gear 12 is fixedly connected to a rotating rod 9. The rotating rod 9 passes through the outer shell 2 and is fixedly connected to a first cutting knife 10.

[0029] By setting the telescopic rod 6 and the spring 7, when the two outer shells 2 are installed on the line, the line squeezes the tapered roller 11, causing the mounting bracket 8 to approach the inner wall of the outer shell 2, and the spring 7 rebounds the mounting bracket 8, making the tapered roller 11 always stick to the line. The advantage of this is that it can adapt to more models of lines and clear obstacles on various different models of lines. By setting the first cutting knife 10, when the tapered roller 11 rotates, it can drive the rotating rod 9 to rotate, causing the first cutting knife 10 to also rotate accordingly, clearing obstacles on the side of the line. At the same time, when the outer shell 2 rotates around the line, it will also drive the first cutting knife 10, causing the first cutting knife 10 to rotate around the line, further expanding the clearing range of the first cutting knife 10 and preventing branches from extending to the line from the side and causing harm.

[0030] The technical solution provided by the present utility model, by setting the tapered roller 11, the first gear 12, the second gear 15, the third gear 16, and the fourth gear 17, in use, the outer shells 2 are symmetrically installed through the connecting plate 21, and the line passes through the outer shell 2 through the through hole 22. The staff can install a motor (not shown in the figure) on the first gear 12 inside the outer shell 2. After installation, the motor is started to make the first gear 12 rotate, driving the tapered roller 11 to roll along the line, causing the outer shell 2 to move on the line. When the first gear 12 rotates, it drives the third gear 16 to rotate through the rack 13, causing the second gear 15 to also rotate accordingly, and then driving the fourth gear 17 meshing with it to rotate, making the second cutting knife 19 rotate, cutting the branches in front, clearing the obstacles in front of the current line without damaging the line, and eliminating the need for manual operation of holding the obstacle clearing device high, reducing the labor intensity and facilitating the operation of the staff.

[0031] By setting the fifth gear 18 and the saw teeth 20, when the outer shell 2 moves, the rotation of the fourth gear 17 will cause the rotating shaft to drive the fifth gear 18 to rotate in the groove 5 of the second sealing plate 4. Since the fifth gear 18 meshes with the saw teeth 20, the second sealing plate 4, the outer shell 2 and the first sealing plate 3 rotate when the fifth gear 18 rotates, and rotate along the line on the line. The advantage of this is that when the outer shell 2 moves, it rotates itself to drive the second cutting knife 19 to rotate around the line, expanding the range of clearing obstacles in front of the line and better clearing the line of obstacles.

[0032] By setting the telescopic rod 6 and the spring 7, when installing the two outer shells 2 on the line, the line squeezes the conical roller 11, causing the mounting bracket 8 to approach the inner wall of the outer shell 2. The spring 7 rebounds against the mounting bracket 8, keeping the conical roller 11 always in contact with the line. The advantage of this is that it can adapt to more types of lines and clear obstacles for various different types of lines. By setting the first cutting knife 10, when the conical roller 11 rotates, it can drive the rotating rod 9 to rotate, causing the first cutting knife 10 to also rotate and clear obstacles on the side of the line. At the same time, when the outer shell 2 rotates around the line, it will also drive the first cutting knife 10 to rotate around the line, further expanding the clearing range of the first cutting knife 10 and preventing branches from extending to the line from the side and causing harm.
