[0050] Hereinafter, exemplary embodiments will be described in detail, and examples thereof are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0051] In the prior art, inspection robots are usually used to inspect overhead transmission lines. The inspection robot includes walking wheels, and the walking wheels are provided with grooves which are matched with the overhead transmission lines. During use, the overhead transmission lines are located in the grooves so that the overhead transmission lines are not easily detached from the walking wheels. However, when inspecting overhead transmission lines with different diameters, it is necessary to replace the walking wheels that are matched with the inspected overhead transmission lines.

[0052] Based on this, an embodiment of the present application provides a driven wheel structure of an inspection device, including: at least one driven wheel group, the driven wheel group includes a mounting frame and at least two rollers, the rollers are rotatably arranged on the mounting frame, the rollers are sequentially spaced apart, and two adjacent rollers are inclined relative to each other to form a receiving groove for receiving the conductors or ground wires of the overhead transmission line. The receiving groove can accommodate conductors or ground wires of various diameters of the overhead transmission line, so that the driven wheel structure can be applicable to conductors or ground wires of various diameters of the overhead transmission line. When the inspection device inspects conductors or ground wires of different diameters of the overhead transmission line, there is no need to replace the driven wheel structure.

[0053] The embodiments of the present application will be described below with reference to the accompanying drawings.

[0054] Refer to Figures 1 to 8 As shown in the figure, the driven wheel structure 100 of the inspection device provided by the present application includes: at least one driven wheel group 110, the driven wheel group 110 includes a mounting frame 111 and at least two rollers 112, the rollers 112 are rotatably arranged on the mounting frame 111, the rollers 112 are sequentially spaced apart, and two adjacent rollers 112 are inclined relative to each other to form a receiving groove 115 for receiving the conductors or ground wires 10 of the overhead transmission line.

[0055] Among them, the overhead transmission line is a power transmission facility erected above the ground and is used to transmit electric energy between two points. The overhead transmission line mainly consists of main components such as conductors, ground wires (lightning protection wires), towers, insulators, and fittings. These components work together to ensure that the current can be safely and effectively transmitted from the power generation station to the user end. As the main current carrier, the conductor usually uses steel-core aluminum stranded wire to optimize the conductivity and mechanical strength. The ground wire is installed above the conductor and is grounded through the tower to reduce the chance of lightning directly hitting the conductor. The tower is used to support the conductor and the ground wire and keep a safe distance between them and the ground and other structures. The insulator ensures the electrical isolation between the conductor and the tower and prevents current leakage.

[0056] The inspection device provided by the embodiment of the present application can be used to be arranged on the conductor or on the ground wire. Of course, two inspection devices can also be arranged, and the two inspection devices are respectively arranged on the conductor and the ground wire.

[0057] The number and size of the rollers 112 can be adaptively set according to actual needs.

[0058] It is understandable that the thickness of the mounting bracket 111 can be less than the diameter of the roller 112, so that part of the roller 112 is located outside the mounting bracket 111. In this way, the mass of the mounting bracket 111 can be made smaller, and thus the weight of the driven wheel structure can be reduced. Of course, the thickness of the mounting bracket 111 can also be greater than or equal to the diameter of the roller 112, and the roller 112 can be entirely located inside the mounting bracket 111, and thus the roller 112 can be protected by the mounting bracket 111.

[0059] Furthermore, there is a certain gap between two adjacent rollers 112 to prevent the rollers 112 from rubbing against adjacent rollers 112 during rotation, which may affect the rotation of the rollers 112.

[0060] In the driven wheel structure 100 of the inspection device provided by the embodiment of the present application, at least two rollers 112 are arranged on the mounting bracket 111, so that the rollers 112 jointly define a receiving groove 115 for receiving the conductors or ground wires 10 of the overhead transmission line. The receiving groove 115 can accommodate conductors or ground wires 10 of various diameters of the overhead transmission line, and thus the driven wheel structure can be applicable to conductors or ground wires 10 of various diameters of the overhead transmission line. When the inspection device inspects conductors or ground wires 10 of different diameters of the overhead transmission line, there is no need to replace the driven wheel structure 100.

[0061] Refer to Figure 2 and Figure 6 , in some examples, the number of rollers 112 in the driven wheel group 110 is two, and both of the two rollers 112 are used to abut against the conductors or ground wires 10 of the overhead transmission line.

[0062] Among them, the two rollers 112 are inclined relative to each other to form a V-shaped receiving groove 115, and thus the conductors or ground wires 10 of the overhead transmission line are received through the receiving groove 115. Both of the two rollers 112 are always in contact with the conductors or ground wires 10 of the overhead transmission line. The contact area between the roller 112 and the conductors or ground wires 10 of the overhead transmission line is large, and the roller 112 is not easily stuck in the gap between two adjacent strands of the conductors or ground wires 10 of the overhead transmission line, so that the driven wheel group 110 has good stability when moving on the conductors or ground wires 10 of the overhead transmission line.

[0063] In specific implementation, the two rollers 112 form an inverted V-shaped structure.

[0064] Among them, the driven wheel structure 100 is located above the conductors or ground wires 10 of the overhead transmission line, and the notch of the receiving groove 115 formed by the two rollers 112 faces downward, so that the two rollers 112 form an inverted V-shaped structure, and thus the conductors or ground wires 10 of the overhead transmission line can be received between the two rollers 112.

[0065] In some embodiments, the included angle between the axes of the two drums 112 is greater than or equal to 60 degrees and less than or equal to 120 degrees.

[0066] Specifically, when the included angle between the axes of the two drums 112 is between 60 degrees and 120 degrees, the receiving groove 115 formed by the two drums 112 can accommodate wires of various existing sizes and specifications. Thereby, the applicability of the driven wheel structure 100 is relatively wide.

[0067] It can be understood that, in specific use, the included angle between the axes of the two drums 112 can be adaptively set according to the diameter of the conductor or ground wire 10 of the specific overhead transmission line. Among them, the smaller the diameter of the conductor or ground wire 10 of the overhead transmission line, the smaller the included angle between the axes of the two drums 112.

[0068] In specific implementation, the diameter of the drum 112 is greater than or equal to three times the diameter of the strands of the conductor or ground wire 10 of the overhead transmission line.

[0069] Among them, the conductor or ground wire 10 of the overhead transmission line is stranded by multiple strands. The diameter of the drum 112 can be greater than or equal to three times the diameter of a single strand, so that the driven wheel structure 100 has better running performance on the conductor or ground wire 10 of the overhead transmission line.

[0070] Exemplarily, the diameter of the drum 112 can be set to five times the diameter of a single strand.

[0071] Refer to Figure 7 and Figure 8 In some examples, the number of drums 112 in the driven wheel group 110 is three or five.

[0072] Among them, the drums 112 are arranged in sequence to enclose and form the receiving groove 115, and at least part of the conductor or ground wire 10 of the overhead transmission line is located in the receiving groove 115.

[0073] It can be understood that the included angle between the axes of two adjacent drums 112 is an obtuse angle. Specifically, the specific degree of the included angle between the axes of two adjacent drums 112 can be adaptively set according to the size of the conductor or ground wire 10 of the overhead transmission line.

[0074] Furthermore, the number of drums 112 in the driven wheel group 110 can also be an odd number such as seven or nine.

[0075] In specific implementation, at least one drum 112 is used to abut against the conductor or ground wire 10 of the overhead transmission line.

[0076] When the driven wheel set 110 moves on the conductor or ground wire 10 of the overhead transmission line, it may move in the vertical direction of the extension direction of the conductor or ground wire 10 of the overhead transmission line, thereby causing the position of the driven wheel set 110 to shift. At this time, at least one roller 112 abuts against the conductor or ground wire 10 of the overhead transmission line and rotates along the conductor or ground wire 10 of the overhead transmission line so that the driven wheel set 110 can move stably along the conductor or ground wire 10 of the overhead transmission line.

[0077] Referring to Figure 5 , in some embodiments, the mounting bracket 111 has a plurality of insertion slots 1112. The roller 112 includes a roller body 1121 and a rotating shaft 1122. The roller body 1121 is sleeved on the rotating shaft 1122, and both ends of the rotating shaft 1122 are correspondingly inserted into the insertion slots 1112.

[0078] Among them, by providing the insertion slots 1112, both ends of the rotating shaft 1122 are correspondingly inserted into the insertion slots 1112 to facilitate the connection between the roller 112 and the mounting bracket 111.

[0079] Exemplarily, the rotating shaft 1122 is fixedly connected to the insertion slot 1112. The roller body 1121 is sleeved on the rotating shaft 1122, and the roller body 1121 can rotate relative to the rotating shaft 1122, so that the roller 112 can rotate relative to the mounting bracket 111.

[0080] In some other examples, the roller body 1121 is sleeved on the rotating shaft 1122 and fixedly connected to the rotating shaft 1122. The rotating shaft 1122 is inserted into the insertion slot 1112 and can rotate relative to the insertion slot 1112, so that the roller 112 can rotate relative to the mounting bracket 111.

[0081] Referring to Figure 5 , in a specific implementation, the mounting bracket 111 includes a first mounting member 1111 and a second mounting member 1113. The insertion slot 1112 is located on the first mounting member 1111 or the second mounting member 1113. The second mounting member 1113 is connected to the first mounting member 1111 to block the insertion slot 1112.

[0082] Exemplarily, the insertion slot 1112 is located on the first mounting member 1111. The second mounting member 1113 is connected to the first mounting member 1111 to block the insertion slot 1112 and fix both ends of the rotating shaft 1122 on the mounting bracket 111, thereby fixing the roller 112 on the mounting bracket 111.

[0083] In some examples, the insertion slot 1112 is located on the second mounting member 1113. The first mounting member 1111 is connected to the second mounting member 1113 to block the insertion slot 1112.

[0084] In some other examples, the first mounting member 1111 has a plurality of first grooves, and the second mounting member 1113 has a plurality of second grooves. The first grooves and the second grooves are joined to form a socket groove 1112.

[0085] In a specific implementation, the mounting bracket 111 has an avoidance groove 1114, and the avoidance groove 1114 is located between two mutually inclined drums 112.

[0086] Wherein, when the mounting bracket 111 is inclined relative to the overhead transmission line conductor or ground wire 10 and is not perpendicular, the overhead transmission line conductor or ground wire 10 is more likely to contact the part of the mounting bracket 111 between the two drums 112. At this time, if the drum 112 rotates along the overhead transmission line conductor or ground wire 10, it will cause friction between the overhead transmission line conductor or ground wire 10 and the part of the mounting bracket 111 between the two drums 112, and generate resistance to the rotation of the drum 112 along the overhead transmission line conductor or ground wire 10. Therefore, an avoidance groove 1114 is provided on the mounting bracket 111, and the avoidance groove 1114 is located between two adjacent drums 112 to avoid the overhead transmission line conductor or ground wire 10 and prevent the overhead transmission line conductor or ground wire 10 from contacting the part of the mounting bracket 111 between two adjacent drums 112.

[0087] Refer to Figure 3 、 Figure 4 and Figure 5 In some embodiments, the driven wheel set 110 further includes a cleaning member 113. The cleaning member 113 is connected to the mounting bracket 111, and the cleaning member 113 is used to remove debris on the overhead transmission line conductor or ground wire 10.

[0088] Wherein, when there is snow or other debris on the overhead transmission line conductor or ground wire 10, if the driven wheel set 110 contacts the debris, it will affect the movement of the driven wheel set 110 on the overhead transmission line conductor or ground wire 10. Therefore, a cleaning member 113 is provided on the driven wheel set 110, so that before the drum 112 contacts the debris on the overhead transmission line conductor or ground wire 10, the cleaning member 113 first contacts the debris on the overhead transmission line conductor or ground wire 10, and the cleaning member 113 removes the debris on the overhead transmission line conductor or ground wire 10, thereby facilitating the movement of the drum 112 on the overhead transmission line conductor or ground wire 10.

[0089] The cleaning member 113 is connected to the mounting bracket 111 to fix the cleaning member 113 on the mounting member 111.

[0090] Exemplarily, the number of the driven wheel sets 110 is two. The cleaning member 113 of one of the driven wheel sets 110 is connected to the side of the mounting frame 111 facing away from the other driven wheel set 110, so that the cleaning member 113 contacts the debris on the overhead transmission line conductor or ground wire 10 before the drum 112 contacts the debris on the overhead transmission line conductor or ground wire 10.

[0091] Referring to Figure 4 and Figure 5 , in a specific implementation, the cleaning member 113 includes a first connecting plate 1131 and a cleaning plate 1132. The first connecting plate 1131 connects the mounting frame 111 and the cleaning plate 1132, and the cleaning plate 1132 is used to remove the debris on the overhead transmission line conductor or ground wire 10.

[0092] Among them, the first connecting plate 1131 is connected to the mounting frame 111 to fix the first connecting plate 1131 on the mounting frame 111. The cleaning plate 1132 is connected to the mounting frame 111 through the first connecting plate 1131. The cleaning plate 1132 can be parallel to the mounting frame 111, and the debris on the overhead transmission line conductor or ground wire 10 is removed by the cleaning plate 1132.

[0093] Exemplarily, when the driven wheel set 110 moves along the overhead transmission line conductor or ground wire 10, the cleaning plate 1132 contacts the debris on the overhead transmission line conductor or ground wire 10 to push the debris on the overhead transmission line conductor or ground wire 10 off the overhead transmission line conductor or ground wire 10, thereby removing the debris on the overhead transmission line conductor or ground wire 10.

[0094] In a specific implementation, there is a spacing between the cleaning plate 1132 and the drum 112.

[0095] Among them, by setting a spacing between the cleaning plate 1132 and the drum 112, when the drum 112 rotates along the overhead transmission line conductor or ground wire 10, it is avoided that the drum 112 contacts the cleaning plate 1132 to generate friction and resistance to the rotation of the drum 112.

[0096] It can be understood that the spacing can be specifically set adaptively according to actual needs, and this embodiment does not limit it here.

[0097] Exemplarily, the first connecting plate 1131 is connected between the cleaning plate 1132 and the mounting frame 111, so that there is a spacing between the cleaning plate 1132 and the drum 112.

[0098] Referring to Figure 5 , in some embodiments, the cleaning member 113 further includes a second connecting plate 1133, and the second connecting plate 1133 connects the first connecting plate 1131 and the mounting frame 111.

[0099] Among them, by setting the second connecting plate 1133, the second connecting plate 1133 is connected to one side of the mounting frame 111, and the connecting surface between the second connecting plate 1133 and the mounting frame 111 is relatively large, so that the connection between the second connecting plate 1133 and the mounting frame 111 is relatively stable. Thus, the connection between the cleaning member 113 and the mounting frame 111 is relatively stable and reliable.

[0100] Exemplarily, the shape and size of the second connecting plate 1133 match the shape and size of the side surface of the mounting frame 111. The second connecting plate 1133 and the cleaning plate 1132 are arranged on the same side of the first connecting plate 1131.

[0101] In some examples, the cleaning plate 1132, the first connecting plate 1131 and the second connecting plate 1133 are integrally formed.

[0102] Refer to Figure 5 , in specific implementation, the cleaning plate 1132 has a notch 1134, and the notch 1134 is used to match with part of the conductors or ground wires 10 of the overhead transmission line.

[0103] Among them, by setting the notch 1134 on the cleaning plate 1132, the notch 1134 cooperates with at least the upper half of the conductors or ground wires 10 of the overhead transmission line, so as to facilitate the cleaning plate 1132 to clean the sundries on the conductors or ground wires 10 of the overhead transmission line.

[0104] It should be noted that there is a gap between the cleaning plate 1132 and the conductors or ground wires 10 of the overhead transmission line, so that the cleaning plate 1132 does not contact the conductors or ground wires 10 of the overhead transmission line. Thus, when the driven wheel set 110 moves along the conductors or ground wires 10 of the overhead transmission line, it is avoided that the cleaning plate 1132 generates friction with the conductors or ground wires 10 of the overhead transmission line and generates resistance to the movement of the driven wheel set 110.

[0105] Exemplarily, the notch 1134 is an arc-shaped notch.

[0106] Refer to Figure 3 and Figure 5 , in specific implementation, the cleaning member 113 has a relief hole 1135.

[0107] Among them, the cleaning member 113 is connected to the mounting frame 111 by screws. By setting the relief hole 1135, the screws are avoided, so that the screws can be connected to the cleaning member 113 and the mounting frame 111 through the relief hole 1135, thus facilitating the connection between the cleaning member 113 and the mounting frame 111.

[0108] Exemplarily, the second connecting plate 1133 is connected to the mounting frame 111, part of the relief holes 1135 are located on the first connecting plate 1131, and the remaining relief holes 1135 are located on the cleaning plate 1132.

[0109] Reference Figure 3 Figure 3 , in some embodiments, the driven wheel structure 100 provided by the embodiments of the present application further includes at least one connecting member 120. The number of the driven wheel groups 110 is at least two, and the connecting member 120 connects the mounting frames 111 of at least two driven wheel groups 110.

[0110] Among them, by providing the connecting member 120 to connect the driven wheel groups 110, so that each driven wheel group 110 can move synchronously along the conductor or ground wire 10 of the overhead transmission line.

[0111] Exemplarily, the connecting member 120 is an elastic member.

[0112] Reference Figure 3 、 Figure 4 and Figure 5 Figure 5 , in specific implementation, the driven wheel group 110 further includes a fixing member 114. The connecting member 120 is located between the mounting frame 111 and the fixing member 114, and the mounting frame 111 is connected to the fixing member 114.

[0113] Among them, the connection manner between the fixing member 114 and the mounting frame 111 can be screw-bolt connection, snap connection, bonding or welding, etc.

[0114] Exemplarily, there is a plug-in slot between the mounting frame 111 and the fixing member 114, and the connecting member 120 is inserted into the plug-in slot.

[0115] Reference Figure 1 and Figure 2 Figure 2 , on the basis of the above embodiments, the embodiments of the present application further provide an inspection device, including: a driving structure 200 and the driven wheel structure 100 of the inspection device.
