DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0038] In order to make the purpose, technical solutions and advantages of the implementation methods of this application clearer, the technical solutions in the implementation methods of this application will be clearly and completely described below in conjunction with the drawings in the implementation methods of this application. Obviously, the described implementation methods are part of the implementation methods of this application, not all of the implementation methods. Based on the implementation methods in this application, all other implementation methods obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0039] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0040] A laser removal device for foreign matter on power grid system lines according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0041] See also Figure 1-Figure 12 According to an embodiment of the present application, a laser removal device for foreign matter in a power grid system line includes: a mobile main body mechanism 1, a laser removal mechanism 2, a supporting mechanism 3 and a weed cutting mechanism 4.

[0042] Among them, the mobile main body mechanism 1 can drive the laser cleaning mechanism 2, the supporting mechanism 3 and the weed cutting mechanism 4 to move all together, and the weed cutting mechanism 4 can cut the grass in the dense grass. After cutting, the mobile main body mechanism 1 is more convenient to move, that is, the supporting mechanism 3 is more convenient to move as a whole, which reduces the difficulty of the operator to transfer the supporting mechanism 3. After the supporting mechanism 3 on the mobile main body mechanism 1 is transferred to the designated position, the supporting mechanism 3 is controlled according to the corresponding operating tool to cut the branches near the power grid line.

[0043] See also Figure 1 , Figure 2 , Figure 4-Figure 7 The mobile main body mechanism 1 includes a frame 11, an electric drive assembly 15 and a steering assembly 16. A rear axle 14 is rotatably arranged at the rear bottom of the frame 11, and rear wheels 12 are installed at both ends of the rear axle 14. The electric drive assembly 15 is installed at the bottom of the frame 11 to drive the rear axle 14 to rotate, and front wheels 13 are arranged on both sides of the bottom front of the frame 11. A handrail 17 is connected to the top of the steering assembly 16, and the steering assembly 16 drives the front wheel 13 to change the forward direction of the front wheel 13. The laser cleaning mechanism 2 includes an electric pan-tilt head 22 and a laser generator 23. A fixed frame 21 is fixed on the frame 11, the electric pan-tilt head 22 is installed on the top of the fixed frame 21, and the laser generator 23 is installed on the electric pan-tilt head 22. The support mechanism 3 includes a support plate 31, and the bottom of the support plate 31 is tilted and supported on the front side above the frame 11 by a support leg 32. The weed cutting mechanism 4 includes a pulley 41, a drive motor 42, a rope segment 45, a fixing part 46 and an end weight-increasing assembly 47. Two rotating shafts 43 are rotatably arranged in front of the support plate 31, a pulley 41 is fixedly sleeved outside the rotating shaft 43, a driving motor 42 is installed on the back of the support plate 31 to drive the rotating shaft 43 to rotate, and the output shaft end of the driving motor 42 is connected to the bottom end of the rotating shaft 43. A transmission belt 44 is arranged outside the two pulleys 41, one end of the rope segment 45 is connected to the outside of the transmission belt 44 through a fixing portion 46, and an end weight-increasing component 47 is arranged at the other end of the rope segment 45.

[0044] The electric drive assembly 15 in the mobile main body mechanism 1 drives the rear axle 14 to drive the rear wheel 12 to rotate, and cooperates with the front wheel 13 to realize the overall movement of the cleaning device. The handrail 17 is rotated, and the forward direction of the rear wheel 12 can be adjusted through the cooperation of the steering assembly 16, that is, the moving direction of the cleaning device is changed. The electric pan / tilt 22 can adjust the emission angle of the laser generator 23, and the laser generator 23 can cut off the branches near the power grid circuit. In the process of the cleaning device moving forward, the output shaft end of the drive motor 42 drives the rotating shaft 43 to rotate, and the rotating rotating shaft 43 drives the external pulley 41 to rotate, and the two sets of pulleys 41 drive the external transmission belt 44 to move rapidly in the same direction and speed. The fast-moving transmission belt 44 will drive the external rope segment 45 to move through the fixed part 46. Under the gravity of the rope segment 45 itself and the gravity of the end weight-increasing assembly 47, the fast-moving transmission belt 44 will drive the rope segment 45 and the end weight-increasing assembly 47 to swing, and the fast-swinging rope segment 45 is straightened to cut off the impurities in the dense grass in front. As the clearing equipment moves forward, the grass in front is cut at the same time, reducing the height of the grass in front, making it easier for the obstacle removal equipment to move quickly to a suitable position in the dense grass, and improving the movement and work efficiency of the laser clearing equipment in the dense grass.

[0045] The centrifugal cutting of grass by the rope segment 45 outside the transmission belt 44 driven by the driving motor 42 driving the pulley 41 has the following advantages: compared with the weeds cut by the blade, the weeds cut by the rotating rope segment 45 are safer for the operator, that is, the rotating rope segment 45 will only cause less harm to the operator than the blade. The end weighting assembly 47 set at the end of the rope segment 45 rotates centrifugally together with the rope segment 45, so that the rope segment 45 has a greater centrifugal force when rotating, and the weeds in front of the device are cut more effectively, that is, it is easier to cut the weeds.

[0046] The frame 11 may be equipped with a corresponding mobile power source and a control switch. The electric drive assembly 15 includes a motor and a gear set, and the rear axle 14 and the rear wheel 12 are driven to rotate by the cooperation of the motor and the gear set.

[0047] In the above specific implementation, please refer to Figure 3The steering assembly 16 includes a shaft frame 162, a transmission shaft 163, a turntable 164, a cross plate 165, a seat plate 166, a U-shaped seat 167, a vertical shaft 168 and a cross shaft 169. The two U-shaped seats 167 are fixed to both sides of the vehicle frame 11, respectively. The vertical shaft 168 is rotatably arranged with the U-shaped seat 167, and one end of the cross shaft 169 is fixed with the vertical shaft 168 to form a horizontally inverted T-shaped structure. The turntable 164 is rotatably arranged above the seat plate 166, the bottom end of the transmission shaft 163 is fixedly installed with the turntable 164, the middle part of the cross plate 165 is rotatably arranged with the seat plate 166 through the first pin shaft, and one end of the cross plate 165 is rotatably arranged with the turntable 164 through the second pin shaft, one end of the shaft frame 162 is rotatably arranged with the cross plate 165 through the third pin shaft, and the other end of the shaft frame 162 is rotatably sleeved outside the cross shaft 169. The handrail 17 is mounted on the top of the transmission shaft 163 , and the front wheel 13 is rotatably arranged at the end of the horizontal shaft 169 .

[0048] The rotating handrail 17 can drive the transmission shaft 163 below to rotate, and the rotating transmission shaft 163 drives the rotating disk 164 to rotate at the same time. The rotating rotating disk 164 drives the two horizontal plates 165 on both sides to rotate respectively through the second pin shaft, and the rotating horizontal plate 165 drives the horizontal shaft 169 to rotate a certain angle around the vertical shaft 168 through the shaft frame 162, that is, the moving horizontal shaft 169 drives the front wheel 13 at the end to change a certain angle. When the front wheel 13 of the cleaning device changes its angle and the rear wheel 12 rolls forward again, the overall forward direction of the cleaning device can be changed.

[0049] For further information, see Figure 1 A limit plate 18 is fixed on the frame 11, and a limit opening is set in the middle of the limit plate 18, and the transmission shaft 163 moves through the limit opening. The limit opening on the limit plate 18 is used to limit the transmission shaft 163 to rotate stably, that is, the transmission shaft 163 will not deviate along the radial direction of the transmission shaft 163 when rotating.

[0050] For specific settings, see Figure 8 and Fig. 9The fixing part 46 includes a first clamping seat 461, a second clamping seat 462 and a positioning block 463. The positioning block 463 connects the transmission belt 44 and the second clamping seat 462, and an avoidance groove for installing the positioning block 463 is provided on the inner side of the transmission belt 44, and the positioning block 463 and the second clamping seat 462 are fixed by bolts. The first clamping seat 461 can detachably fix one end of the rope segment 45 with the second clamping seat 462 through the fixing bolt 464. The first clamping seat 461 and the second clamping seat 462 are both provided with an arc groove 465 on the opposite side of the second clamping seat 462 for clamping the end of the rope segment 45. The inner wall of the arc groove 465 is equidistantly provided with multiple groups of tooth blocks 466 with arc structures. One end of the rope segment 45 is clamped in the arc groove 465 between the first clamping seat 461 and the second clamping seat 462, and the end of the rope segment 45 between the first clamping seat 461 and the second clamping seat 462 is fastened by the fixing bolt 464. The tooth block 466 on the inner wall of the arc groove 465 can increase the friction between the first clamping seat 461 and the second clamping seat 462 and the rope segment 45, so that the rope segment 45 between the first clamping seat 461 and the second clamping seat 462 is fixed more firmly and is not easy to fall off during centrifugal rotation. When the rope segment 45 is damaged, the rope segment 45 can be quickly replaced by removing the fixing bolt 464 and the first clamping seat 461.

[0051] In the above specific implementation, please refer to Fig.10 The end weight-increasing component 47 includes a flexible sphere 471 and a flexible protrusion 474. The flexible sphere 471 is provided with an annular groove 472 for receiving the rope segment 45 in the middle, and a rope threading hole 473 is provided in the middle of the annular groove 472. The rope segment 45 can move through the rope threading hole 473. The flexible protrusions 474 are symmetrically arranged on the inner side walls of the annular groove 472 in pairs, and a gap is reserved between the two symmetrically arranged flexible protrusions 474 for the rope segment 45 to pass through. The flexible sphere 471 and the flexible protrusion 474 are made of an integrally formed rubber material or latex material.

[0052] The method for installing the flexible sphere 471 is as follows: one end of the rope segment 45 passes through the rope hole 473 on the ring groove 472 in the middle of the flexible sphere 471, and a knot is tied at one end of the rope segment 45 passing through the rope hole 473 to prevent the rope segment 45 from falling off from the rope hole 473. When the rope segment 45 moves centrifugally to cut weeds, the flexible sphere 471 is located at the end of the rope segment 45, providing better centrifugal force to the rope segment 45, so that the moving rope segment 45 can be stretched tighter and straighter, and the moving rope segment 45 has better cutting ability. The flexible sphere 471 is made of rubber or latex material with good elasticity. When a person accidentally touches the flexible sphere 471 and the rope segment 45, the damage caused to the human body can be effectively reduced.

[0053] When the weed removal equipment does not need to perform weed removal operations, or after the equipment is used, the flexible sphere 471 at the end of the rope segment 45 can be rotated to roll the rope segment 45 around the annular groove 472 in the middle of the flexible sphere 471, that is, the rope segment 45 passes through the gap between the symmetrically arranged flexible protrusions 474, and the rope segment 45 is rolled inside the annular groove 472. The flexible protrusions 474 can prevent the rolled rope segment 45 from loosening. In this way, when the rope segment 45 is not used for cutting, it can be rolled inside the annular groove 472 in the flexible sphere 471. When the cutting operation is needed again, the driving motor 42 drives the pulley 41 to drive the transmission belt 44 to move, and the transmission belt 44 drives the outer rope segment 45 and the flexible sphere 471 to perform centrifugal motion. The rolled rope segment 45 stuck inside the annular groove 472 can be quickly thrown out under the action of centrifugal force for cutting operation, that is, the rope segment 45 rolled inside the flexible sphere 471 does not need to be released manually, and can be opened automatically when the cutting operation is performed.

[0054] For details, please refer to Fig.11 The support mechanism 3 also includes a cover plate 33, a top plate 34 and a connecting plate 35. The cover plate 33 is located above the pulley 41, and the top of the rotating shaft 43 is rotatably arranged with the cover plate 33. The top plate 34 is fixed to the top of the supporting plate 31 by welding, and the connecting plate 35 connects the cover plate 33 and the top plate 34 by bolts. The cover plate 33 is supported above the pulley 41 by the top plate 34 and the connecting plate 35, which plays a good protective role for the pulley 41 and the transmission belt 44. The support mechanism 3 also includes a lower vertical plate 36 and an upper vertical plate 37. The upper vertical plate 37 is fixed below the top of the cover plate 33, and the lower vertical plate 36 is located below the upper vertical plate 37 and connected to the supporting plate 31, and a gap is left between the lower vertical plate 36 and the upper vertical plate 37 for the rope segment 45 to pass through. The setting of the lower vertical plate 36 and the upper vertical plate 37 plays a shielding role, preventing the weeds splashed during cutting from entering between the supporting plate 31 and the cover plate 33 and affecting the transmission belt 44 and the pulley 41. The rotating rope segment 45 passes through the gap between the lower vertical plate 36 and the upper vertical plate 37 .

[0055] When the above-mentioned power grid system line foreign body laser removal equipment is performing weed cutting operations, although the flexible sphere 471 brings better effect to the rope segment 45, during the frequent cutting action, it will also cause the rotating rope segment 45 to be easily attached with the cut and broken weeds. The weeds attached to the rope segment 45 cannot be cleaned, which will affect the subsequent rope segment 45's cutting efficiency of the weeds in front of the equipment.

[0056] See also Fig.11 and Fig.12The power grid system line foreign body laser removal device also includes a linkage cleaning mechanism 5, which includes an L-shaped fixed rod 51, a beam 52, a fixed block 53, a lower baffle 54 and a buffer 55. A notch 39 is provided on the support plate 31. The lower baffle 54 is located below the notch 39, multiple groups of fixed blocks 53 are fixed on both sides of the lower baffle 54, and the buffer 55 connects the fixed block 53 and the back of the support plate 31. The bottom end of the fixed rod 51 is fixedly connected to the top of the vertical axis 168, one end of the beam 52 is fixedly connected to the fixed rod 51, and the other end of the beam 52 is in contact with the bottom wall of the lower baffle 54, and the upper baffle 38 is fixed on the top of the upper vertical plate 37, and the upper baffle 38 is located above the notch 39.

[0057] The driving motor 42 drives the pulley 41 to drive the transmission belt 44 and the external rope segment 45 to rotate and cut the weeds in front of the equipment. During the process of the rope segment 45 rotating to perform the cutting operation, the rope segment 45 can pass through the gap between the lower vertical plate 36 and the upper vertical plate 37, and the rotating rope segment 45 is located below the upper baffle 38. When the handrail 17 is rotated, the rotating handrail 17 drives the transmission shaft 163 below to rotate together, and the rotating transmission shaft 163 finally drives the horizontal shaft 169 to rotate around the vertical shaft 168 through the bottom turntable 164, the horizontal plate 165 and the shaft frame 162, that is, the forward direction of the front wheel 13 is changed at this time. At the same time, the rotating vertical shaft 168 will drive the upper fixed rod 51 to rotate synchronously, and the rotating fixed rod 51 drives the top beam rod 52 to move. When the obstacle clearing device is moving straight normally, under the elastic force of the buffer 55, the lower baffle 54 is located below the notch 39. Once the front wheel 13 is rotated to one direction, the vertical shaft 168 rotates at the same time, driving the fixed rod 51 and the beam 52 to rotate. The synchronously rotating beam 52 presses against the bottom of the lower baffle 54 and compresses the buffer 55. The lower baffle 54 moves upward, and the top of the lower baffle 54 passes through the notch 39. A small gap is finally reserved between the lower baffle 54 and the upper baffle 38, and the gap can be passed through by the rope segment 45, and the end weight-increasing assembly 47 at the top of the rope segment 45 passes through the space between the top of the upper baffle 38 and the top plate 34. When the rotating rope segment 45 passes through the gap between the upper baffle 38 and the lower baffle 54, the weeds attached to the rope segment 45 can be blocked by the upper baffle 38 and the lower baffle 54, and then fall off or are cut off by the rope segment 45, which plays a role in cleaning the weeds on the rope segment 45. This structural design can not only clean the weeds on the rope segment 45 while mowing, but also rotate the armrest 17 to adjust the distance between the lower baffle 54 and the upper baffle 38 as needed to clean the weeds on the rope segment 45, that is, the weeds attached to the rope segment 45 can be cleaned synchronously while the cleaning equipment moves forward and turns.
