DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] Embodiment 1: This embodiment provides a power grid transmission line detection device, specifically, Figure 1-Figure 4 , Fig.11 As shown, it includes a drone 1. The drone 1 is a prior art well known to the public, and its specific working principle is not repeated here. The drone 1 is equipped with a debris capturing component 2 and a debris removing component 4. The debris removing component 4 is used to clean the debris wound on the cable 5. The debris capturing component 2 uses negative pressure to capture the scattered debris cleaned by the debris removing component 4.

[0030] The debris removal component 4 includes an adjustment mechanism and a shearing mechanism; the adjustment mechanism includes a first adjustment motor 401 fixedly mounted on the drone 1, and a second adjustment click 402 rotatably connected to the drone 1, the output end of the first adjustment motor 401 is connected to the second adjustment click 402, the output end of the second adjustment click 402 is installed with a mounting frame 403, a mounting rod 409 is installed on the mounting frame 403, a shearing mechanism is installed on the mounting rod 409, and a second spring 411 is arranged between the shearing mechanism and the mounting rod 409; the shearing mechanism includes a first shearing knife unit 416, a second shearing knife unit 418 and a control unit for respectively controlling the opening and closing of the first shearing knife unit 416 and the second shearing knife unit 418, and the shearing mechanism achieves the purpose of shearing debris through the opening and closing of the first shearing knife unit 416 and the second shearing knife unit 418.

[0031] like Figure 2 As shown, when the drone 1 is close to the debris and is stable, the first adjustment motor 401 can be started according to the position of the debris such as balloons or plastic bags, and the first adjustment motor 401 drives the second adjustment click 402 to rotate to change the inclination angle of the mounting frame 403 and the horizontal plane, so that the shearing mechanism comes to the position where shearing is required to operate; then the first adjustment motor 401 adjusts the inclination angle of the second adjustment click 402 to make the shearing mechanism contact the surface of the cable 5 and cut off the debris wrapped around its surface; if the wrapped object is Fig.11 In the state shown, i.e., the cable 5 is wound along the axial direction, the second adjustment click 402 is activated at this time, the second adjustment click 402 drives the mounting frame 403 to rotate 90 degrees, and the first adjustment motor 401 is used to make the mounting frame 403 vertically downward, at this time the second spring 411 is squeezed, the first shearing knife unit 416 and the second shearing knife unit 418 are pressed on the cable 5, and the shearing mechanism can cut off the rope or other debris wound along the circumference of the cable 5. Through the setting of the first adjustment motor 401 and the second adjustment click 402, the shearing mechanism can clean up various forms of debris wound on the cable 5, thereby improving the cleaning quality.

[0032] The debris capturing component 2 includes a fan motor 205 and a filter plate 204 installed on the drone 1 . A fan 203 is installed on the fan motor 205 . When the fan 203 rotates, the debris is adsorbed on the filter plate 204 .

[0033] Before the debris removal component 4 starts working, the fan motor 205 is started, and the fan 203 starts to rotate. Under the action of the fan 203, air is blown from the bottom of the drone 1 to the top. Therefore, after the debris removal component 4 cleans the debris, these lightweight airflows or plastic bags will be adsorbed on the filter plate 204 to prevent these debris from floating in the wind, and more importantly, to prevent these debris from affecting the flight of the drone 1.

[0034] Through the above-mentioned settings, the device does not require manual cleaning by staff, which reduces the labor intensity of staff and reduces the occurrence of safety accidents such as falling and electric shock; at the same time, it can clean various forms of debris entangled on the cable 5 with high cleaning quality; at the same time, it can capture the cleared debris to prevent it from being scattered by the wind and affecting the environment.

[0035] Based on the above-mentioned equipment, this embodiment also provides a power grid transmission line detection method, which is specifically as follows: first, the staff controls the drone 1 to fly to the cable 5 entangled with debris, so that the drone 1 is above the debris; then the debris capture component 2 is started, and the debris begins to be adsorbed on the filter plate 204, ensuring that the debris has a certain stability, which paves the way for the operation of the debris removal component 4; then the debris removal component 4 is started, and the debris is cut off by the debris removal component 4 to ensure that there is no debris entangled on the surface of the cable 5, and the debris is completely adsorbed on the filter plate 204; finally, the debris removal component 4 is folded up, and the debris capture component 2 continues to operate until the drone 1 returns to the ground, at which time the debris capture component 2 is turned off, and the debris is removed to complete the entire cleaning process.

[0036] Embodiment 2: This embodiment is further expanded on the basis of the above embodiment. Figure 2 , Figure 7 , Figure 8 As shown, the UAV 1 is also equipped with a plurality of retractable components 3, and the retractable components 3 include a base frame 305 installed on the UAV 1, and the base frame 305 is rotatably connected to a support tube 303, a second electric cylinder 306, and a first connecting rod 307, the second electric cylinder 306 is rotatably connected to the first connecting rod 307, the first connecting rod 307 is rotatably connected to a second connecting rod 308, the second connecting rod 308 is rotatably connected to the support tube 303, a support rod 304 is installed on the support tube 303, and a pulley is installed on the support rod 304.

[0037] When the drone 1 is close to the debris and is above the cable 5, the second electric cylinder 306 is started. At this time, the second electric cylinder 306 extends and synchronously pushes the first connecting rod 307. The first connecting rod 307 pushes the second connecting rod 308 in a linked manner. The second connecting rod 308 drives the support tube 303 to start swinging downward, that is, drives the support rod 304 to make the pulley unfold downward, and then the support rod 304 presses on the cable 5 (such as Figure 2 As shown in the figure, and the distance between the drone 1 and the cable 5 can be adjusted by the extension and contraction of the second electric cylinder 306, so as to ensure that the capture capability of the debris capture component 2 is maximized. The pulley allows the drone 1 to have a simple foothold. On the one hand, the cable 5 can be used to limit the pulley to reduce the impact of the airflow flowing in the sky on the drone 1, improve the hovering stability of the drone 1, and facilitate the subsequent operation of the debris removal component 4; on the other hand, the cable 5 is used to support the pulley, and part of the gravity of the drone 1 is borne by the cable 5, which can reduce the lift power output by the drone 1, thereby reducing power consumption and improving the endurance of the drone 1.

[0038] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0039] Embodiment 3: This embodiment further expands the retractable component 3 on the basis of the above embodiment. Figure 7 , Figure 8 As shown, a stabilizing motor 313 is installed on the base frame 305, and a second gear 312 is installed on the stabilizing motor 313; the support rod 304 is rotatably connected to the support cylinder 303, the support rod 304 is rotatably connected to the third connecting rod 309, the third connecting rod 309 is rotatably connected to the fourth connecting rod 310, the fourth connecting rod 310 is rotatably connected to the transmission shaft 314, the transmission shaft 314 is rotatably connected to the base frame 305, and a first gear 311 is installed on the transmission shaft 314, and the first gear 311 is meshed with the second gear 312.

[0040] After the pulley is pressed on the cable 5, before the debris removal component 4 adjusts its position and prepares to start the cleaning operation, the stabilizing motor 313 is started, the stabilizing motor 313 drives the second gear 312, the second gear 312 drives the first gear 311, the first gear 311 drives the transmission shaft 314, the transmission shaft 314 drives the fourth connecting rod 310, the fourth connecting rod 310 drives the third connecting rod 309, and the third connecting rod 309 drives the support rod 304 to rotate. At this time, the two slides rotate at the same time, so the pulley will give the cable 5 a torsional force, thereby increasing the friction force so that the pulley can be fixed on the cable 5, that is, the drone 1 at this time will not be blown by the airflow, causing the pulley to move on the cable 5, thereby reducing the power consumption of the airflow in the drone 1 and further improving its stability when hovering. When on the ground, the pulley can also support the drone 1. If the stabilizing motor 313 is started at the same time, the pulley can be used as a guide wheel, so that the drone 1 can glide on the ground without manual carrying.

[0041] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0042] Embodiment 4: This embodiment further expands the retractable component 3 on the basis of the above embodiment. Figure 7 , Figure 8 As shown, in the retractable assembly 3 near the debris removal assembly 4, an L-shaped through hole is provided on the support rod 304; a baffle 202 and an air pipe 201 are installed on the drone 1, and the air pipe 201 passes through the through hole of the transmission shaft 314 and is connected to the through hole on the support rod 304.

[0043] When the fan 203 rotates, part of the airflow is intercepted by the baffle 202, and then the intercepted airflow enters the air delivery pipe 201, and finally ejected from the L-shaped through hole on the support rod 304. At this time, the ejected airflow will cause the debris on the cable 5 to be subjected to a force approaching the other retractable component 3, that is, it can effectively prevent the debris removing component 4 from being directly moved upward by the negative pressure at the filter plate 204 when cutting off the debris, causing the debris to stick to the debris removing component 4. This arrangement can ensure that the debris bypasses the debris removing component 4 and is then adsorbed on the filter plate 204, and will not affect the normal operation of the debris removing component 4.

[0044] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0045] Embodiment 5: This embodiment further expands the retractable component 3 on the basis of the above embodiment. Fig. 9 As shown, in the retractable assembly 3 away from the debris removal assembly 4, a through hole is provided on the support rod 304 along the axis; a camera 315 is installed in the through hole of the support rod 304, and the transmission line of the camera 315 passes through the through hole of the transmission shaft 314 and returns to the drone 1; the pulley includes two pulley units 301, and the pulley unit 301 is sleeved on the support rod 304, and a first spring 302 is provided between the support rod 304 and the pulley unit 301.

[0046] When the pulley is pressed on the cable 5, due to the gravity of the drone 1, the first spring 302 will be compressed, and the two pulley units 301 will move away from each other until the cable 5 contacts the rotating shaft of the pulley unit 301. At this time, the cable 5 is closest to the camera 315. By setting the first spring 302, cables 5 of different diameters can be as close to the camera 315 as possible; after the debris on the cable 5 is cut off, the drone 1 moves on the cable 5, so that the camera 315 moves back and forth at the debris cutting position, and the camera 315 can capture clearer image information of the position, so as to observe whether the cable 5 is damaged during the cutting process.

[0047] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0048] Embodiment 6: This embodiment further expands the debris removal component 4 on the basis of the above embodiment. Figure 3 As shown, the adjustment mechanism also includes a fifth connecting rod 404 rotatably connected to the mounting frame 403, the fifth connecting rod 404 is rotatably connected to the seventh connecting rod 407 and the eighth connecting rod 408, the eighth connecting rod 408 is rotatably connected to the mounting rod 409, the seventh connecting rod 407 is rotatably connected to the sixth connecting rod 405, the sixth connecting rod 405 is rotatably connected to the mounting frame 403, and a third adjusting motor 406 is installed on the mounting frame 403, and the third adjusting motor 406 is transmission-connected to the sixth connecting rod 405; an arc-shaped slide rail is provided on the mounting frame 403, and the mounting rod 409 moves on the arc-shaped slide rail.

[0049] When the shearing mechanism is performing shearing operations, Figure 2 As shown, the third adjusting motor 406 can be started at this time, the third adjusting motor 406 drives the sixth connecting rod 405, the sixth connecting rod 405 pulls the seventh connecting rod 407, and the seventh connecting rod 407 pulls the fifth connecting rod 404 and the eighth connecting rod 408, thereby pushing the mounting rod 409 to slide in the arc track on the mounting frame 403. When the mounting rod 409 slides in the arc track, the shearing mechanism will move along the circumference of the cable 5, thereby cutting off debris at different circumferential positions of the cable 5, thereby improving the cutting quality.

[0050] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0051] Embodiment 7: This embodiment further expands the debris removal component 4 on the basis of the above embodiment. Figure 4-Figure 6 As shown, the shearing mechanism includes a shearing cylinder seat 410, a second spring 411 is arranged between the shearing cylinder seat 410 and the mounting rod 409, the shearing cylinder seat 410 is rotatably connected to the first shearing cylinder 415, the first shearing cylinder 415 is rotatably connected to the second shearing cylinder 417, the first shearing knife unit 416 is installed on the first shearing cylinder 415, the second shearing knife unit 418 is installed on the second shearing cylinder 417, a shearing motor 412 is installed on the shearing cylinder seat 410, the shearing motor 412 is transmission-connected to the driving shaft 413, and the shearing cylinder seat 410 is axially slidably connected to the sliding pin 414; a wavy and closed groove is arranged on the driving shaft 413, and a spiral groove is arranged on the first shearing cylinder 415 and the second shearing cylinder 417, and the spiral grooves of the two are opposite in rotation direction; the sliding pin 414 passes through the spiral grooves on the first shearing cylinder 415 and the second shearing cylinder 417 in turn, and finally cooperates with the groove on the driving shaft 413.

[0052] When the adjustment mechanism completes the position adjustment of the shearing mechanism, the shearing motor 412 is started, and the shearing motor 412 drives the driving shaft 413 to rotate. When the driving shaft 413 rotates, due to the wavy and closed grooves arranged thereon, the sliding pin 414 will reciprocate on the shearing cylinder seat 410. When the sliding pin 414 reciprocates, due to the setting of the spiral groove, the sliding pin 414 will also push the first shearing cylinder 415 and the second shearing cylinder 417 to reciprocate forward and reverse, that is, the first shearing knife unit 416 and the second shearing knife unit 418 will continuously open and close back and forth to shear, thereby completing the shearing operation of the debris.

[0053] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0054] Embodiment 8: This embodiment further expands the debris capture component 2 on the basis of the above embodiment.

[0055] When the balloon-like debris is adsorbed on the filter plate 204, the first electric cylinder 206 extends, and the fan motor 205 and the fan 203 extend synchronously, driving the needle holder 208 to move, that is, the puncture needle 207 begins to puncture the balloon on the filter plate 204, thereby puncturing the balloon; then the first electric cylinder 206 is retracted, and the puncture needle 207 returns to the top of the filter plate 204 to ensure that the puncture needle 207 is not punctured when manually removing the debris on the filter plate 204. The puncture needle 207 can puncture the airflow, reduce the volume of the balloon, prevent it from affecting the capture ability of the debris capture component 2, and prevent the adsorption from being unstable.

[0056] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0057] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form.
