Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of power maintenance, and specifically to a lightning strike induced discharge protection device for vegetation near power lines. Background Art
[0002] In the actual operation of the power system, distribution overhead lines extend widely to urban and rural areas. The surrounding environment is complex, and there is often a large amount of shrub vegetation growing. Among them, the patent with publication number CN113839345B discloses a lightning strike induced discharge protection device for vegetation near power lines and its usage method, revealing that these shrub vegetations will significantly affect the electric field distribution near the power lines during the operation of the power lines. When the shrub vegetation is lush and close to the power lines, it will cause distortion of the electric field around the lines, thereby changing the traveling trajectory of the lightning leader, greatly increasing the probability of the thundercloud hitting the power lines, and triggering the phenomenon of induced lightning strike discharge. Once the lightning strike discharge occurs, situations such as line short - circuit, tripping, and damage to power equipment are likely to occur, seriously threatening the safe and stable power supply of the power system.
[0003] This technical solution includes a fixing device, on which a weed collection device and an angle adjustment device are installed. An herb pulling device is installed on the angle adjustment device, and a grass clamping device is installed on the herb pulling device. The herb pulling device can pull weeds and cut down taller shrubs.
[0004] However, this device still has certain defects when in use:
[0005] First of all, when this lightning strike induced discharge protection device for vegetation near power lines performs pruning and maintenance operations on the shrub vegetation around the power lines, the roots of the pruned shrub vegetation are sharp. During subsequent inspections and maintenance work by construction workers, they are extremely likely to be stabbed in the feet due to accidental stepping, causing physical harm to the construction workers.
[0006] Secondly, after the pruning operation of this lightning strike induced discharge protection device for vegetation near power lines, the cut shrub vegetation is directly recycled into the grass box. Since the intact shrub vegetation takes up a lot of space, the grass box will be filled up after cutting for a while, and manual cleaning is required, which greatly affects the work efficiency. Summary of the Invention

[0008] Aiming at the deficiencies of the prior art, the present invention provides a lightning strike induced discharge protection device for vegetation near power lines, which has the advantages of preventing the distortion of the electric field near the distribution overhead lines by clearing the shrub vegetation around the power lines, thereby preventing the thundercloud from hitting the lines, and being able to round the roots of the pruned shrub vegetation to prevent the feet of construction workers from being stabbed by the roots of the pruned shrub vegetation as much as possible, solving the problems raised in the background art.

[0024] (III) Beneficial effects
[0025] Compared with the prior art, the present invention provides a lightning-induced discharge protection device for vegetation near power lines, which has the following beneficial effects:
[0026] 1. For the lightning-induced discharge protection device for vegetation near power lines, the cutting mechanism on the material receiving shell is used to remove the shrub vegetation around the power lines. Specifically, the first motor is started to drive the first rotating rod to rotate, so that the pushing mechanism on the rotating strip works, and the position of the material receiving shell is adjusted to accurately dock with the vegetation. Subsequently, the second motor is started to drive the cutting disc to rotate at a high speed to complete the cutting. In this way, the electric field distortion caused by the lush vegetation near the overhead distribution lines can be reduced, thereby reducing the probability of the thundercloud hitting the lines, preventing the occurrence of lightning-induced discharge phenomena, ensuring the safe and stable power supply of the power system, reducing the situations such as line short circuits, tripping, and damage to power equipment caused by lightning strikes, maintaining the normal supply of electricity, and avoiding the inconvenience and economic losses brought by power outages to production and life.
[0027] 2. For the lightning-induced discharge protection device for vegetation near power lines, since the device is provided with a grinding mechanism, when the first rotating rod rotates to drive the transmission shell to move horizontally, after the square block moves in place and presses the third motor switch and the fourth motor switch, the third motor and the fourth motor are automatically started. The third motor drives the second rotating rod to rotate to make the turntable rotate, and the fourth motor drives the grinding rod to rotate, and the roots of the cut vegetation are rounded and ground into an arc shape. This treatment method effectively avoids the situation that construction workers are stabbed in the feet by the sharp roots of the shrub vegetation due to accidental stepping during subsequent inspection and maintenance work, maximally guarantees the physical safety of construction workers, reduces the occurrence of work-related injuries, and creates a safer working environment for construction workers.
[0028] 3. For the lightning-induced discharge protection device for vegetation near power lines, the crushed vegetation can be crushed by the crushing mechanism inside the wood receiving shell. When the first transmission mechanism drives the transmission shell to move horizontally and reset, the second transmission mechanisms on both sides start to work. The transmission shell drives the transmission rod to move through the connecting rod, and then drives the rack to slide upward, meshing with the gear on one side, so that the cross bar and the crushing roller rotate. The two crushing rollers rotate towards each other to crush the vegetation. At the same time, the guide plate in the wood receiving shell can guide the vegetation to smoothly enter between the crushing rollers, enabling the wood receiving shell to store more vegetation, eliminating the need for frequent manual cleaning, reducing the time and labor spent on cleaning the vegetation, and improving the overall work efficiency.
[0029] 4. The lightning strike discharge protection device for the power line near vegetation ensures the stable movement of the transmission shell through the limit shell and the square block in the stabilizing mechanism. When the transmission shell moves, the connecting rods on both sides drive the square block to slide stably in the limit shell, thus ensuring the stable operation of the grinding mechanism, improving the quality and effect of grinding. The spring in the second transmission mechanism plays a buffering and resetting role, absorbing and dispersing the impact force during the transmission process, avoiding damage to the equipment caused by excessive instantaneous force, helping each component to accurately reset at the same time, ensuring the stable operation of the crushing mechanism, reducing the occurrence probability of equipment failures, extending the service life of the equipment, and reducing the maintenance cost of the equipment.
[0030] 5. The lightning strike discharge protection device for the power line near vegetation monitors the torque of the second motor during cutting in real time through the motor torque detection sensor and transmits the data to the PLC control cabinet. When the torque is too large during cutting of thick vegetation, the PLC control cabinet reduces the speed of the second motor to prevent damage to the motor due to high-load operation; when the torque is small during cutting of thin vegetation, the speed is increased to improve the cutting efficiency, further enhancing the working efficiency of the device.
[0031] 6. In the lightning strike discharge protection device for the power line near vegetation, the piston rod of the hydraulic cylinder in the pushing mechanism expands and contracts, and the receiving shell is pushed to move towards or away from each other through the connecting plate. It can flexibly adjust the position of the receiving shell according to the size, shape and position of different vegetation, enabling the device to adapt to various complex vegetation distribution situations, improving the applicability of the device and the convenience of operation. The operator does not need to spend a lot of time and energy adjusting the overall position of the equipment, and only needs to control the pushing mechanism to easily complete the position adjustment of the receiving shell, reducing the operation difficulty and labor intensity.
[0032] 7. In the lightning strike discharge protection device for the power line near vegetation, due to the close linkage relationship between the various mechanisms, the rotation of the first motor can drive the position adjustment of the receiving shell, the movement of the transmission shell and the operation of the crushing mechanism at the same time. In addition, when the square block moves into place, the third motor and the fourth motor are automatically started and automatically shut down during reset, and the motor torque detection sensor and the PLC control cabinet cooperate to automatically adjust the speed of the second motor, etc., all of which reflect the high degree of automation of the device, reduce manual intervention, reduce the work intensity of the operator, improve the accuracy and stability of operation at the same time, and make the entire vegetation treatment process more efficient and smooth.

[0058] In summary, when the lightning strike discharge protection device for vegetation near the power line is in use, it is mainly used to process the vegetation near the power line. Through operations such as cutting, grinding, and crushing, the impact of the vegetation on the power line is reduced. Its working process is completed by the cooperation of multiple mechanisms, and there is a linkage relationship between the mechanisms. When it is necessary to process the vegetation near the power line, the first motor 23 is started. The first motor 23 drives the first rotating rod 6 to rotate, and the rotating bars 7 at both ends of the first rotating rod 6 rotate accordingly. The pushing mechanism on the rotating bar 7 starts to work. The piston rod of the hydraulic cylinder 8 in the pushing mechanism expands and contracts, and through the connecting plate 9, it pushes the receiving shell 10 to move towards or away from each other, thereby adjusting the positions of the two receiving shells 10 so that they can accurately dock the vegetation to be processed. The second motor 12 is started. The second motor 12 drives the cutting disc 13 to rotate at high speed. The motor torque detection sensor 15 monitors the torque during the cutting of the second motor 12 in real time and transmits the data to the PLC control cabinet 14. When encountering thicker vegetation during the cutting process, which causes excessive torque, the PLC control cabinet 14 reduces the speed of the second motor 12 to prevent damage caused by the high-load operation of the second motor 12. When cutting thinner vegetation with less torque, the PLC control cabinet 14 increases the speed of the second motor 12 to improve the cutting efficiency. The cut vegetation falls into the interior of the receiving shell 10. The first motor 23 rotates in reverse, causing the rotating bar 7 to rotate to the vertical position. The receiving shell 10 pours the vegetation into the wood collecting shell 2. When the first rotating rod 6 rotates, the first transmission mechanism at its middle end starts to work. The push rod 24 rotates with the first rotating rod 6 and pushes the fixed frame 25 to move through the round pin 26, that is, drives the transmission shell 17 to move horizontally. When the transmission shell 17 moves, the connecting rods 34 on both sides of it drive the square block 36 to slide in the limit shell 35. Since the square block 36 slides stably in the limit shell 35, it can maintain the stable movement of the transmission shell 17, and further maintain the stable movement of the grinding mechanism. When the square block 36 moves into place, the third motor switch 42 and the fourth motor switch 43 on the inner wall of the limit shell 35 are pressed, automatically starting the third motor 22 and the fourth motor 20. The third motor 22 drives the second rotating rod 18 to rotate, causing the turntable 19 to rotate;The fourth motor 20 drives the grinding rod 21 to rotate, and grinds the surface of the cut vegetation to grind the root of the cut vegetation into an arc shape, which is not likely to cause foot stabbing of the staff. After grinding, the cutting of the next piece of vegetation can be carried out, that is, the first rotating rod 6 rotates again to drive the rotating bar 7 to rotate to the horizontal. During this period, the first transmission mechanism drives the transmission housing 17 to move horizontally and reset, and the second transmission mechanisms on both sides start to work. The transmission housing 17 drives the transmission rod 33 to move through the connecting rod 34. The transmission rod 33 drives the rack 29 to slide upward through the pin 32 and the connecting block 31. The rack 29 meshes with the gear 30 on one side, thereby driving the gear 30 on one side to rotate, and then driving the cross bar 3 and the crushing roller 4 to rotate. The gears 30 on the two cross bars 3 mesh with each other, so that the two crushing rollers 4 rotate towards each other to crush the vegetation falling into the wood collection housing 2. The guide plate 16 in the wood collection housing 2 can guide the vegetation to smoothly enter between the crushing rollers 4, that is, it can ensure that more vegetation can be stored in the wood collection housing 2, and there is no need to frequently manually take out the vegetation, thereby improving work efficiency. Through the above series of operations, the protection device completes the cutting, grinding and crushing of the vegetation near the power line, effectively reducing the impact of the vegetation on the power line and ensuring the safe operation of the power line.
