[0043] Embodiment 1:

[0044] like Figure 1-Figure 4 As shown, an anti-twisting suspension wire includes a suspension wire body 1 and a pulley 2. The suspension wire body 1 is constructed as a closed frame structure. The frame structure has opposite upper and lower ends. The upper end of the frame structure is provided with at least two connection points 101. The lower end of the frame structure is detachably connected to the pulley 2 through a suspension member 3.

[0045] The anti-twist suspension wire is constructed into a frame-like structure through the suspension wire body 1. The frame-like structure has a larger contact area with surrounding objects, which helps to improve the load-bearing capacity. Compared with a single rope, the frame-like structure also has better wind resistance. The anti-twist suspension wire is connected to the hoisting member 3 through the pulley 2. Any suitable materials can be hoisted on the hoisting member 3, which helps to broaden the scope of use.

[0046] When working at high altitude, the drone body 4 is connected to the pulley 2 through the suspension wire body 1. The pulley 2 is heavy and is hoisted with materials of a certain weight, so that the overall center of gravity height is lowered. Combined with the weight of the pulley 2 and the materials, it helps to increase the wind resistance and reduce the swing. Moreover, since the state of the pulley 2 and the materials is more stable, it is easier for the staff to correct the angle deviation, which improves the convenience of alignment and reduces the difficulty of the operation and the labor intensity of the staff.

[0047] Specifically, the upper end of the frame structure is connected to the drone body 4 through a connection point 101, and thanks to the larger volume of the frame structure, multiple connection points 101 can be provided, so the connection between the anti-twist suspension wire and the drone body 4 is more stable. The hoisting member 3 is detachably connected to the pulley 2. When performing electrical aerial work, the pulley 2 is detached from the hoisting member 3 and mounted on the wire, thereby facilitating the next step of operation.

[0048] For example, when arranging the lifting and landing ropes, the drone body 4 is connected to the pulley 2 through the suspension wire body 1, and the pulley 2 is connected to the lifting and landing ropes. After the connection is completed, the drone body 4 moves vertically upward and drives the suspension wire body 1, the pulley 2 and the lifting and landing ropes to rise into the air. The connection between the lifting and landing ropes and the pulley 2 is lifted. According to the length of the lifting and landing ropes, the two ends of the lifting and landing ropes are located on the ground or near the ground. When the pulley 2 rises to the vicinity of the wire, the pulley 2 is aligned with the wire, and the drone body 4 moves horizontally to allow the pulley 2 to hang on the wire, and then the drone body 4 is moved to separate the hoisting part 3 from the pulley 2, thereby completing the arrangement of the lifting and landing ropes.

[0049] It is easy to understand that items such as transfer ropes and tool kits replace the take-off and landing ropes, so that the drone body 4 can transfer the required items to the high-altitude workers, which expands the scope of use and is more practical.

[0050] It is easy to understand that the frame structure formed by the suspension wire body 1 can be a rectangular frame, an isosceles trapezoidal frame, or any other suitable frame shape.

[0051] It is easy to understand that the hanging member 3 can be a hanging ring, or the hanging member 3 can also be any other suitable existing component.

[0052] In a possible implementation, the connection point 101 is constructed as a knot. Based on the above design, the suspension line body 1 can select any suitable existing rope, and the selection range is wide. And the rope is knotted to form a knot, which is not only used to connect the drone body 4, but also does not require other connection equipment, reducing the use of parts. Further, the knot can be constructed as any suitable existing structure to adapt to different work requirements.

[0053] In a possible implementation, at least one support rod 102 is provided in the frame-like structure, and the support rod 102 divides the frame-like structure into a plurality of sub-frames. Based on the above design, the support rod 102 makes the structural strength of the frame-like structure better, so as to improve the bearing capacity of the frame-like structure. And according to the length of the frame-like structure and specific working requirements, those skilled in the art can set any appropriate number of support rods 102.

[0054] In a possible implementation, the pulley 2 includes a base 21, a hanger 22 and a hanging structure 23;

[0055] The base 21 is provided with a hanging groove 201 for connecting the wires, the upper end of the hanging groove 201 is provided with a slide plate 202, and the lower end of the hanging groove 201 has two opposite sides, one of which is provided with a mounting hole outside the hanging groove 201, and the other side is provided with an opening 203 connected to the outside;

[0056] The hanger 22 is disposed on the base 21 and has an upper and lower end, the upper end of the hanger 22 is located outside the base 21 and is used to connect the frame structure, and the lower end of the hanger 22 is slidably disposed on the mounting hole;

[0057] The hanging structure 23 includes a base plate 231 and a connecting rope 232. The base plate 231 is rotatably arranged at the opening 203 and is used to control the opening and closing of the opening 203. One end of the connecting rope 232 is connected to the base plate 231, and the other end of the connecting rope 232 is connected to the lower end of the hanger 22. Accordingly, the sliding of the hanger 22 is used to drive the base plate 231 to rotate.

[0058] Based on the above design scheme, a lifting groove 201 for connecting the wire is provided on the base 21, so that the pulley 2 can connect the wire and slide along the wire; the lifting groove 201 is large in size, which can not only expand the volume of the opening 203 to facilitate the connection, but also reserve space, so that even if the wire is twisted, it will not affect the connection between the pulley 2 and the wire; the lifting groove 201 contacts the wire through the slide plate 202, and the friction coefficient of the slide plate 202 is low, which helps to reduce the wear of the wire; in addition, the base 21 can be constructed in any suitable shape.

[0059] The hanger 22 is used to connect the hoisting member 3 to realize the connection between the pulley 2 and the suspension wire body 1, and the hanger 22 can be constructed in any suitable structure. The hoisting structure 23 controls the opening and closing of the opening 203 through the base plate 231. When the wire is plugged into the hoisting slot 201, the opening 203 is closed in time to prevent the pulley 2 from separating from the wire. At the same time, the base plate 231 is connected to the hanger 22 through the connecting rope 232, and the hanger 22 is connected to the drone body 4, so that the movement of the drone body 4 during the hoisting process controls the movement of the base plate 231, thereby controlling the opening and closing of the opening 203.

[0060] Specifically, when the drone body 4 lifts the pulley 2, the hanger 22 and the base 21 move relative to each other, and the position of the hanger 22 moves up relative to the base 21, and the connecting rope 232 is tightened, thereby driving the base plate 231 to rotate and open the opening 203. When the opening 203 is aligned with the wire, the drone body 4 moves laterally to allow the wire to enter the lifting groove 201. At this time, the drone body 4 moves again and causes the suspension wire body 1 to separate from the pulley 2. After the external force is lost, the hanger 22 will move downward under the action of gravity, the connecting rope 232 is loosened, and the base plate 231 also rotates under the action of gravity and closes the opening 203, thereby closing the lifting groove 201.

[0061] Based on this, the drone body 4 and the base plate 231 are linked through the connection of the hanger 22. No additional equipment is required to provide power, and no additional operation is required to control the base plate 231, thereby simplifying the operation and work intensity of the staff and helping to improve the speed of operation.

[0062] Preferably, if Figure 4 As shown, the base 21 includes two plates arranged opposite to each other and a plurality of connectors for connecting the two plates. Based on this, the base 21 is made into a hollow structure to reduce the weight of the base 21 and avoid the base 21 being overweight, thereby helping to improve the endurance performance of the drone body 4. It is easy to understand that the connectors are selected from any suitable existing parts such as screws, shafts, etc.

[0063] Preferably, if Figure 3 As shown, the base 21 is provided with a guide member 204 located outside the opening 203, and two guide members 204 are provided and are respectively located at the upper and lower ends of the opening 203, and one end of the two guide members 204 connected to the base 21 is close to each other and connected to the base 21, and the two ends of the two guide members 204 away from the base 21 are separated from each other, so as to increase the area of ​​the opening 203, increase the convenience of aligning the wire, and can guide the moving direction of the wire, so that the pulley 2 is more convenient to connect the wire.

[0064] It is easy to understand that the guide member 204 can be any suitable existing component such as a plate-shaped component or a frame structure.

[0065] Alternatively, if Figure 4 As shown, the base 21 is provided with a steering wheel 205 between the hanger 22 and the base plate 231, and the connecting rope 232 is wound around the steering wheel 205. Based on this, steering is achieved by the steering wheel 205, and the wear of the connecting rope 232 is reduced.

[0066] In a possible implementation, the hanger 22 includes a base rod 221, a slide seat 222 and a frame body 223;

[0067] The base rod 221 is inserted into the mounting hole and can slide along the mounting hole;

[0068] The lower end of the base rod 221 is located inside the base 21 and connected to the slide 222. Correspondingly, the slide 222 is slidably disposed inside the base 21 and connected to the connecting rope 232. The upper end of the base rod 221 extends outside the base 21 and is connected to the frame 223. The frame 223 is used to connect the hanging member 3.

[0069] The frame 223 includes two obliquely arranged sub-frames 223, the upper ends of the two sub-frames 223 are close to each other and form a connection for connecting the two sub-frames 223, the lower ends of the two sub-frames 223 are far away from each other, and the base rod 221 is connected to the frame 223 through the connection, so that the hanger 22 is umbrella-shaped.

[0070] Based on the above design scheme, the base rod 221 is connected to the connecting rope 232 through the slide 222. The slide 222 is larger in size, which is convenient for connecting the connecting rope 232 and also makes the connection more secure. The base rod 221 is connected to the suspension wire body 1 through the frame 223, and the frame 223 makes the hanger 22 umbrella-shaped through the sub-frame 223. By adjusting the position of the suspension wire body 1, the center point of the camera on the drone body 4 and the center point of the hanger 22 are as close as possible to each other, thereby eliminating the upper and lower height errors. The lateral movement of the drone body 4 is accurately fed back to the pulley 2, which helps to eliminate the angle error and improve the accuracy of the connecting wire. And because the hanger 22 is umbrella-shaped, when the hanging part 3 is connected to the frame 223, under the action of the gravity of the pulley 2, the hanging part 3 slides along the sub-frame 223 to the connection point, and can be moved to the center point of the hanger 22 without additional adjustment.

[0071] Alternatively, if Figure 3 As shown, the sub-frame 223 is constructed as a frame-shaped frame 223, thereby expanding the cross-sectional area of ​​the sub-frame 223 to facilitate the connection of the hanging member 3 to the hanger 22. Alternatively, the sub-frame 223 can also be constructed in any other suitable shape.

[0072] Embodiment 2:

[0073] This embodiment introduces a high-altitude operation drone based on the embodiment 1. Figure 1 and Figure 5-Figure 9 As shown, the aerial work drone includes a drone body 4, the anti-twist suspension wire and supplies. The belly of the drone body 4 is connected to the upper end of the anti-twist suspension wire, and the supplies are detachably connected to the lower end of the anti-twist suspension wire.

[0074] In the aerial work drone, the drone body 4 can be selected from any suitable existing model, and the materials are determined according to the needs of the aerial work, that is, the aerial work drone can be used for any suitable aerial work, including but not limited to aerial work on power towers. The anti-twist suspension wire cooperates with the suspension wire body 1 and the pulley 2 to increase wind resistance and reduce swinging. Since the state of the pulley 2 and the materials is more stable, it is easier for the staff to correct the angle deviation, which improves the convenience of alignment and reduces the difficulty of the operation and the labor intensity of the staff.

[0075] Furthermore, for the drone body 4, the existing model of the equipment is provided with a connecting structure 5 at the belly, which is connected to the camera and other equipment through the connecting structure 5, but for the anti-twist suspension line, it is provided with at least two connection points 101. In this regard, a connecting structure 5 is provided between the drone body 4 and the anti-twist suspension line, and the top surface of the connecting structure 5 is provided with a first connecting unit 501 adapted to the drone body 4, and the bottom surface of the connecting structure 5 is provided with at least two second connecting units 502 adapted to the anti-twist suspension line.

[0076] Based on the above design, the intermediate transition is achieved through the connecting structure 5. On the basis of meeting the anti-twist wire connection requirements, there is no need to modify or customize the drone body 4, which helps to reduce economic costs. It is easy to understand that the first connecting unit 501 is constructed as any suitable existing structure to achieve the connection between the connecting structure 5 and the drone body 4.

[0077] In one possible implementation, the connecting structure 5 includes a base body 51, a slider 52 and a connecting module. The top surface of the base body 51 is provided with the first connecting unit 501, and the bottom surface of the base body 51 is provided with a concave slide groove. The slider 52 is slidably set in the slide groove. The lower end of the slider 52 extends outside the base body 51 and is connected to the connecting module to form a second connecting unit 502. Accordingly, the slider 52 and the connecting module are arranged one by one and are respectively provided with at least two.

[0078] Based on the above design, the slider 52 can slide along the slide slot, thereby adjusting the position of the slider 52 and adjusting the distance between two adjacent sliders 52 to adapt to different connection requirements. The connection module is used to connect the connection point 101 of the anti-twist suspension wire. It is easy to understand that the connection module can be constructed as any suitable structure.

[0079] Furthermore, if the connection structure 5 is used to connect the anti-twist suspension wire, and the connection points 101 of the anti-twist suspension wire are located on the same straight line, then only one slide groove is required and two sliders 52 are required. If it is used to connect other equipment, and its connection points 101 are located on different straight lines, then correspondingly, multiple slide grooves are provided, and each slide groove is provided with at least one slider 52. Based on this, there are multiple layout schemes for the slide groove and the slider 52, and those skilled in the art can determine according to the connection requirements.

[0080] Furthermore, if there are multiple slide grooves, the seat body 51 is constructed as a hollow structure to reduce the weight of the connecting structure 5 and reduce the flight burden of the drone body 4.

[0081] It is easy to understand that when the device connected to the connection structure 5 has a certain rigidity, after the slider 52 is connected to the device through the connection module, the position of the slider 52 can be in a relatively fixed position, but for non-rigid components such as anti-twist suspension wires, the position of the slider 52 needs to be fixed. Therefore, in a possible implementation, a driving part 503 and a vertically arranged driving shaft 504 are provided in the slider 52, the output end of the driving part 503 is connected to the driving shaft 504, and the two ends of the driving shaft 504 are respectively provided with driving threads, and accordingly, the two sections of the driving threads are respectively connected to the upper slide cylinder 505 and the lower slide cylinder 506;

[0082] The upper slide 505 is connected with a pressing block 507 located outside the seat body 51, and the pressing block 507 is provided with a plurality of pressing rods 508 extending outward. The seat body 51 is provided with an additional groove located above the slide groove, and the additional groove is provided with a plurality of limiting grooves adapted to the pressing rod 508. Accordingly, the reciprocating sliding of the upper slide 505 is used for the pressing rod 508 to be inserted into or separated from one of the limiting grooves.

[0083] A control hole communicating with the outside is provided at the lower end of the lower slide cylinder 506, and a control member 509 is detachably provided on the control hole. The lower end of the control member 509 is connected to the connection module through a control rope 510 to control the opening and closing of the connection module.

[0084] Based on the above design, the driving unit 503 provides power to rotate the driving shaft 504, and the driving unit 503 can be any suitable existing device; the driving shaft 504 transmits power through the driving screw to make the upper slide 505 and the lower slide 506 rise and fall respectively. Specifically:

[0085] As for the upper slide 505, a pressing block 507 is connected to the upper slide 505. When the upper slide 505 rises, the pressing block 507 rises and causes the pressing rod 508 to disengage from the limiting groove, eliminating the obstruction of the pressing rod 508 to the movement of the slider 52 along the slide groove. At this time, the slider 52 can be moved along the slide groove, and the position of the slider 52 and the distance between two adjacent sliders 52 can be adjusted. When the slider 52 moves to the desired position, the upper slide 505 descends, the pressing block 507 descends, and causes the pressing rod 508 to be inserted into one of the limiting grooves, thereby fixing the position of the slider 52.

[0086] For the lower slide cylinder 506, the lower slide cylinder 506 is connected to the connection module through the control member 509 and the control rope 510. When the lower slide cylinder 506 descends, the control member 509 descends, and the control rope 510 follows and drives the connection module to move, so that the connection module is opened or closed; when the lower slide cylinder 506 rises, the control member 509 rises, the control rope 510 follows, and the connection module is reset.

[0087] For example, Figure 6 and Figure 7 As shown, the connection module is constructed as an annular structure 513, and a socket and a control panel 514 rotatably arranged on the socket are arranged obliquely above the annular structure 513, the upper end of the control panel 514 is connected to the control rope 510, and the lower end of the control panel 514 is buckled on the annular structure 513. When the lower slide cylinder 506 moves downward, the control rope 510 pulls the control panel 514 to rotate outward to open the annular structure 513; conversely, when the lower slide cylinder 506 rises, the control rope 510 is loosened, and the control panel 514 is reset under the action of gravity and the annular structure 513 is closed.

[0088] Furthermore, a detachable control member 509 is provided on the lower slide cylinder 506. When the opening and closing of the connection module needs to be manually controlled, the staff manually pulls the control member 509, and then controls the opening and closing of the connection module through the control rope 510. Based on this, the use is more flexible and convenient, and the practicality is better.

[0089] Based on this, the upper slide 505 controls whether the pressing block 507 limits the slider 52, and the lower slide 506 controls the opening and closing of the connection module, thereby realizing the linkage between the two. Those skilled in the art can control whether the upper slide 505 and the lower slide 506 are raised and lowered synchronously by controlling the rotation direction of the two driving threads, and then combine the limiting of the slider 52 and the opening and closing of the connection module to form a variety of solutions to adapt to different usage requirements.

[0090] In addition, the speed of the upper slide cylinder 505 and the lower slide cylinder 506 rising and falling can be controlled by controlling the pitch of the driving thread, thereby achieving fine control to adapt to different usage requirements.

[0091] Alternatively, if Figure 6 and Figure 7 As shown, the bottom surface of the pressure rod 508 is provided with an additional plate extending outward, and the additional plate increases the depth of insertion into the limiting groove to ensure the limiting effect. Further, when the upper slide 505 and the lower slide 506 are asynchronously lifted and lowered, when the lower slide 506 moves down, the pressure rod 508 moves up, and the additional plate increases the depth of contact between the pressure rod 508 and the limiting groove, so that when the lower slide 506 moves down a certain distance, the pressure rod 508 can be limited by the additional plate, and on the basis of ensuring the limit, the distance that the lower slide 506 moves down is increased.

[0092] In a possible implementation, the plurality of pressure rods 508 are divided into two limit groups, and the two limit groups are respectively arranged on two oppositely arranged outer surfaces of the pressure block 507. Based on the above design, the pressure block 507 is subjected to uniform force through symmetrical design, so as to extend the service life of the pressure block 507.

[0093] In a possible implementation, the control member 509 includes a base ring 511 and a plug rod 512, and a plurality of plug rods 512 are provided and evenly distributed on the end surface of the base ring 511. Based on the above design, the base ring 511 is used to connect the control rope 510 and is used by the staff, and the plug rod 512 is plugged into the lower slide cylinder 506 and is detachably connected by any appropriate method.

[0094] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
