[0048] Exemplary embodiments will be described in detail below, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments 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.

[0049] In the prior art, the inspection device includes a driving wheel, and the driving wheel abuts against the transmission line. By rotating the driving wheel relative to the transmission line, the inspection device moves on the transmission line, and then the transmission line is inspected. The driving wheel is usually located below the transmission line, and the driving wheel needs to press the transmission line tightly to rotate along the transmission line. When the pressing force of the driving wheel on the transmission line is large, it is not easy for the driving wheel to rotate along the transmission line. When the pressing force of the driving wheel on the transmission line is small, the driving wheel is prone to slip when moving on the transmission line, which affects the movement of the driving wheel on the transmission line and further affects the inspection efficiency of the inspection device. In addition, for different usage scenarios of the inspection device, such as climbing slopes, rainy days or ice-covered transmission lines, etc., the inspection device is prone to slip and cannot move forward.

[0050] Based on this, the embodiment of the present application provides an inspection device. The pressure detection structure is used to detect the pressure applied by the driving structure on the conductor or ground wire of the overhead transmission line to determine the abutting state between the driving structure and the conductor or ground wire of the overhead transmission line. The lifting structure is electrically connected to the pressure detection structure, so that the pressure detection structure can transmit the detected pressure information to the lifting structure. The lifting structure drives the driving structure to lift relative to the main frame according to the pressure information, that is, the driving structure lifts relative to the conductor or ground wire of the overhead transmission line, so as to adjust the abutting state between the driving structure and the conductor or ground wire of the overhead transmission line, and adjust the pressure applied by the driving structure on the conductor or ground wire of the overhead transmission line to a preset pressure. Thereby, it is not easy for the driving structure to slip when moving on the conductor or ground wire of the overhead transmission line, avoiding affecting the inspection efficiency of the inspection device. At the same time, it is more convenient for the driving structure to rotate relative to the conductor or ground wire of the overhead transmission line, which is convenient for the driving structure to drive the inspection device to move along the conductor or ground wire of the overhead transmission line.

[0051] The embodiments of the present application will be described below with reference to the accompanying drawings.

[0052] Refer to Figures 1 to 9, An inspection device provided by an embodiment of the present application includes: a driving structure 100, a main body frame 200, a lifting structure 300, and a pressure detection structure 400. The driving structure 100 is movably connected to the main body frame 200. The driving structure 100 is used to abut against one side of the conductor or ground wire 10 of the overhead transmission line. A part of the main body frame 200 is used to abut against the other side of the conductor or ground wire 10 of the overhead transmission line, so that the driving structure 100 and the main body frame 200 jointly clamp the conductor or ground wire 10 of the overhead transmission line.

[0053] The pressure detection structure 400 is connected to the driving structure 100. The pressure detection structure 400 is used to detect the pressure exerted by the driving structure 100 on the conductor or ground wire 10 of the overhead transmission line. The lifting structure 300 connects the driving structure 100 and the main body frame 200. The lifting structure 300 is electrically connected to the pressure detection structure 400. The lifting structure 300 is configured to lift the driving structure 100 relative to the main body frame 200 according to the pressure, so as to adjust the pressure to a preset pressure.

[0054] 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 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 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.

[0055] 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.

[0056] It can be understood that when the pressure exerted by the driving structure 100 on the conductor or ground wire 10 of the overhead transmission line is small, it will cause the clamping force between the driving structure 100 and the conductor or ground wire 10 of the overhead transmission line to be small, and further cause the driving structure 100 to slip easily when moving on the conductor or ground wire 10 of the overhead transmission line. When the pressure exerted by the driving structure 100 on the conductor or ground wire 10 of the overhead transmission line is large, the driving structure 100 is not easy to rotate relative to the conductor or ground wire 10 of the overhead transmission line, and further causes the driving structure 100 to be not easy to move on the conductor or ground wire 10 of the overhead transmission line, affecting the inspection efficiency of the inspection device.

[0057] The preset pressure is a range value, and the preset pressure can be adaptively set according to actual needs so that when the pressure applied by the driving structure 100 on the overhead transmission line conductor or ground wire 10 is within the preset pressure range, the driving structure 100 is not prone to slipping on the overhead transmission line conductor or ground wire 10, and the movement of the driving structure 100 on the overhead transmission line conductor or ground wire 10 is not affected. The specific range of the preset pressure is not limited in this embodiment.

[0058] Specifically, the driving structure 100 and the main frame 200 jointly clamp the overhead transmission line conductor or ground wire 10 to hang the inspection equipment on the overhead transmission line conductor or ground wire 10. When the pressure detection structure 400 detects that the pressure applied by the driving structure 100 on the overhead transmission line conductor or ground wire 10 is less than a preset pressure, the lifting structure 300 drives the driving structure 100 to move toward the overhead transmission line conductor or ground wire 10 relative to the main frame 200 to increase the pressing force of the driving structure 100 on the overhead transmission line conductor or ground wire 10. When the pressure detection structure 400 detects that the pressure applied by the driving structure 100 on the overhead transmission line conductor or ground wire 10 is greater than a preset pressure, the lifting structure 300 drives the driving structure 100 to move toward the side away from the overhead transmission line conductor or ground wire 10 relative to the main frame 200 to reduce the pressing force of the driving structure 100 on the overhead transmission line conductor or ground wire 10. Thus, the pressure applied by the driving structure 100 to the overhead power line conductor or the ground wire 10 can be adjusted to a preset pressure.

[0059] The inspection device provided in the embodiment of the present application detects the pressure applied by the drive structure 100 to the overhead transmission line conductor or ground wire 10 through the pressure detection structure 400 to determine the abutment state between the drive structure 100 and the overhead transmission line conductor or ground wire 10. The lifting structure 300 is electrically connected to the pressure detection structure 400 so that the pressure detection structure 400 can transmit the detected pressure information to the lifting structure 300. The lifting structure 300 drives the drive structure 100 to rise and fall relative to the main frame 200 based on the pressure information, that is, the drive structure 100 rises and falls relative to the overhead transmission line conductor or ground wire 10 to adjust the abutment state between the drive structure 100 and the overhead transmission line conductor or ground wire 10, and adjusts the pressure applied by the drive structure 100 to the overhead transmission line conductor or ground wire 10 to a preset pressure. As a result, the driving structure 100 is not easy to slip when moving on the overhead transmission line conductor or ground wire 10, thereby avoiding affecting the inspection efficiency of the inspection equipment. At the same time, the driving structure 100 is more convenient to rotate relative to the overhead transmission line conductor or ground wire 10, which makes it easier for the driving structure 100 to drive the inspection equipment to move along the overhead transmission line conductor or ground wire 10.

[0060] Reference Figure 6 、 Figure 7 and Figure 8, in some embodiments, the lifting structure 300 includes a first transmission member 310 and a second transmission member 320. The first transmission member 310 is in driving connection with the second transmission member 320. The first transmission member 310 is connected to the driving structure 100, and the second transmission member 320 is connected to the main body frame 200. The first transmission member 310 is configured to rotate relative to the second transmission member 320 to drive the driving structure 100 to move up and down relative to the main body frame 200.

[0061] Wherein, by providing the first transmission member 310 and the second transmission member 320, the second transmission member 320 is fixed on the main body frame 200, and the first transmission member 310 rotates relative to the second transmission member 320 to drive the first transmission member 310 to move relative to the second transmission member 320, thereby driving the driving structure 100 to move up and down relative to the main body frame 200.

[0062] Exemplarily, the second transmission member 320 is arranged vertically, so that when the first transmission member 310 moves along the second transmission member 320, the driving structure 100 can be driven to rise or fall.

[0063] Specifically, when it is necessary to raise the driving structure 100 relative to the main body frame 200, the first transmission member 310 is rotated relative to the second transmission member 320 in a first direction, so that the first transmission member 310 moves upward relative to the second transmission member 320, thereby driving the driving structure 100 to rise relative to the main body frame 200. When it is necessary to lower the driving structure 100 relative to the main body frame 200, the first transmission member 310 is rotated relative to the second transmission member 320 in a second direction, so that the first transmission member 310 moves downward relative to the second transmission member 320, thereby driving the driving structure 100 to fall relative to the main body frame 200. It can be understood that one of the first direction and the second direction is the clockwise direction and the other is the counterclockwise direction.

[0064] In a specific implementation, the lifting structure 300 further includes a control member, and the control member is connected to the first transmission member 310. The pressure detection structure 400 includes a pressure detection member, the control member is electrically connected to the pressure detection member, and the control member is configured to control the rotation of the first transmission member 310 relative to the second transmission member 320 according to the pressure.

[0065] The control element is electrically connected to the pressure sensing element so that the pressure information detected by the pressure sensing element can be transmitted to the control element. Based on the pressure, the control element can determine whether the drive structure 100 needs to be raised or lowered relative to the main frame 200, and further determine the direction in which the first transmission member 310 needs to rotate relative to the second transmission member 320, as well as the angle or number of rotations. Thus, the pressure between the drive structure 100 and the overhead power line conductor or ground wire 10 can be adjusted to a preset pressure. The provision of the control element enables automatic adjustment of the pressure between the drive structure 100 and the overhead power line conductor or ground wire 10.

[0066] For example, the control element may be a motor.

[0067] In a specific implementation, the first transmission member 310 is a gear, and the second transmission member 320 is a rack meshed with the gear.

[0068] Specifically, the gear is rotated relative to the rack to drive the gear to move relative to the rack, and the rack drives the driving structure 100 to rise and fall relative to the main frame 200.

[0069] In some embodiments, the lifting structure 300 further includes a limiting member 330 , which is connected to the driving structure 100 , and the limiting member 330 contacts a side of the rack away from the gear.

[0070] The stopper 330 contacts the side of the rack facing away from the gear, so that the stopper 330 and the gear jointly clamp the rack, thereby ensuring that the gear and rack are always meshed. When the gear moves relative to the rack, it drives the stopper 330 to move relative to the rack.

[0071] Illustratively, the limiting member 330 may be disposed opposite to the gear.

[0072] Reference Figure 8 In other embodiments, the limiter 330 may be cylindrical and may be connected to the drive structure 100 for rotation. When the gear drives the limiter 330 to move relative to the rack, the limiter 330 simultaneously rotates relative to the rack, converting the sliding friction between the limiter 330 and the rack into rolling friction. This reduces the friction between the limiter 330 and the rack, facilitating the gear-driven movement of the drive structure 100 and the limiter 330 relative to the rack.

[0073] Reference Figure 3 In a specific implementation, the drive structure 100 includes a drive wheel 110 and a host system 120. The drive wheel 110 is disposed on the host system 120. The host system 120 is movably connected to the main frame 200, and the host system 120 is connected to the lifting structure 300. The drive wheel 110 is used to abut against one side of the overhead transmission line conductor or ground wire 10.

[0074] Among them, the driving wheel 110 rotates on the conductor or ground wire 10 of the overhead transmission line, so that the driving wheel 110 moves along the conductor or ground wire 10 of the overhead transmission line. Furthermore, the main machine system 120 can be driven by the driving wheel 110 to move relative to the conductor or ground wire 10 of the overhead transmission line.

[0075] Specifically, the pressure detection structure 400 is connected to the driving wheel 110 to detect the pressure exerted by the driving wheel 110 on the conductor or ground wire 10 of the overhead transmission line. The lifting structure 300 drives the main machine system 120 to lift relative to the main body frame 200, so as to drive the driving wheel 110 to lift relative to the main body frame 200 through the main machine system 120. Furthermore, the driving wheel 110 can move towards the conductor or ground wire 10 of the overhead transmission line or move towards the side away from the conductor or ground wire 10 of the overhead transmission line, so as to adjust the pressure between the driving wheel 110 and the conductor or ground wire 10 of the overhead transmission line.

[0076] Exemplarily, the main machine system 120 includes a control mechanism. The control mechanism is electrically connected to both the lifting structure 300 and the pressure detection structure 400. The pressure detection structure 400 detects the pressure exerted by the driving wheel 110 on the conductor or ground wire 10 of the overhead transmission line, and transmits the pressure information to the control mechanism. The control mechanism controls the lifting structure 300 according to the pressure information to make the driving wheel 110 rise or fall.

[0077] Furthermore, the control mechanism can be electrically connected to the control component of the lifting structure 300 to control the rotation of the first transmission member 310 relative to the second transmission member 320 through the control component, and further control the lifting of the driving wheel 110.

[0078] Referring to Figure 4 and Figure 5 , in a specific implementation, the driving wheel 110 includes a rotating shaft 111 and a wheel body 112 sleeved on the rotating shaft 111. The rotating shaft 111 is connected to the pressure detection structure 400, and the wheel body 112 is used to abut against the conductor or ground wire 10 of the overhead transmission line.

[0079] Among them, the driving wheel 110 includes a driving motor. The driving motor includes a stator and a rotor. The stator is the rotating shaft 111, and the wheel body 112 is sleeved on the rotor. The rotor rotates relative to the stator to drive the wheel body 112 to rotate relative to the conductor or ground wire 10 of the overhead transmission line.

[0080] Exemplarily, the wheel body 112 can be a rubber shell. The rubber shell is sleeved on the rotor. The friction between the rubber shell and the conductor or ground wire 10 of the overhead transmission line is relatively large, so that the friction between the driving wheel 110 and the conductor or ground wire 10 of the overhead transmission line is relatively large, and further the driving wheel 110 is not likely to slip on the conductor or ground wire 10 of the overhead transmission line.

[0081] In some embodiments, the driving structure 100 further includes a connecting member 130, and the connecting member 130 connects the pressure detection structure 400 and the driving wheel 110.

[0082] Wherein, by providing the connecting member 130, it is convenient to connect the pressure detection structure 400 and the driving wheel 110.

[0083] Exemplarily, the connecting member 130 is connected to the rotating shaft 111.

[0084] In a specific implementation, the connecting member 130 includes a first connecting plate 131 and a second connecting plate 132. The first connecting plate 131 is disposed on one side of the second connecting plate 132. The first connecting plate 131 is connected to the driving wheel 110, and the second connecting plate 132 is connected to the pressure detection structure 400.

[0085] Wherein, the first connecting plate 131 and the second connecting plate 132 are inclined to each other. The first connecting plate 131 has a first connecting portion, and the first connecting portion is connected to the rotating shaft 111 of the driving wheel 110. The second connecting plate 132 has a second connecting portion, and the second connecting portion is connected to the pressure detection structure 400.

[0086] Exemplarily, the first connecting portion is a first connecting hole, and the driving wheel 110 is connected to the rotating shaft 111 through the first connecting hole by a mounting member. The second connecting portion is a second connecting hole, and the pressure detection structure 400 is connected to the second connecting hole through the mounting member. For example, the mounting member is a screw or a bolt.

[0087] Further, the rotating shaft 111 has a mounting portion, and the shape of the first connecting plate 131 matches that of the mounting portion, and the first connecting plate 131 is connected to the mounting portion.

[0088] Refer to Figure 2 and Figure 3 , in some embodiments, the host system 120 includes a housing 121 and at least two socket members 122. The driving wheel 110 is disposed on the housing 121. The housing 121 is connected to the lifting structure 300. The socket members 122 are connected to both sides of the housing 121, and the socket members 122 are sleeved on the main body frame 200.

[0089] Specifically, by providing the socket members 122 on both sides of the housing 121, when the lifting structure 300 drives the housing 121 to move up and down relative to the main body frame 200, the socket members 122 can move along the lifting structure 300. Thus, the lifting of the housing 121 can be guided by the socket members 122, and at the same time, the socket members 122 can provide support for the housing 121, so that the stability and reliability of the housing 121 are better.

[0090] Exemplarily, the housing 121 has a receiving groove, a part of the driving wheel 110 is located in the receiving groove, and the rotating shaft 111 of the driving wheel 110 is connected to the housing 121. The first transmission member 310 is connected to one side of the housing 121.

[0091] Furthermore, the pressure detection structure 400 can be connected to the housing 121, and the driving wheel 110 can be connected to the housing 121 through the pressure detection structure 400.

[0092] In a specific implementation, the main body frame 200 includes a frame main body 210 and a driven wheel structure 220 provided on the frame main body 210. The driven wheel structure 220 is used to abut against the other side of the conductor or ground wire 10 of the overhead transmission line. The socket member 122 is sleeved on the frame main body 210, and the lifting structure 300 is connected to the frame main body 210.

[0093] Wherein, the driving wheel 110 rotates relative to the conductor or ground wire 10 of the overhead transmission line so that the driving wheel 110 moves along the conductor or ground wire 10 of the overhead transmission line. At the same time, the driving wheel 110 can drive the driven wheel structure 220 to move along the conductor or ground wire 10 of the overhead transmission line through the host system 120 and the frame main body 210. By providing the driven wheel structure 220, it is convenient for the inspection device to move along the conductor or ground wire 10 of the overhead transmission line.

[0094] Specifically, the driven wheel structure 220 is connected to the upper part of the frame main body 210 and abuts against the upper side of the conductor or ground wire 10 of the overhead transmission line. The driving wheel 110 is located below the driven wheel structure 220 and abuts against the lower side of the conductor or ground wire 10 of the overhead transmission line. The host system 120 is located below the driving wheel 110.

[0095] In some embodiments, the frame main body 210 includes a plurality of support rods 211 and a plurality of fixing members 212. The fixing members 212 and the support rods 211 are arranged at intervals in sequence. The fixing member 212 connects two adjacent support rods 211. Each support rod 211 and each fixing member 212 jointly enclose the frame main body. The socket member 122 is sleeved on the support rod 211. The lifting structure 300 is connected to at least one of the support rod 211 and the fixing member 212.

[0096] Wherein, at least part of the structure of the socket member 122 matches the support rod 211. The socket member 122 is sleeved on the support rod 211 so that when the housing 121 moves up and down relative to the frame body 210, the socket member 122 can move along the support rod 211. Thus, the support rod 211 and the socket member 122 can provide a guiding effect on the housing 121. By providing the fixing member 212, adjacent two support rods 211 are connected. Exemplarily, the support rod 211 is a cylindrical rod.

[0097] In some examples, the socket member 122 is in the shape of a sleeve, and the socket member 122 is directly sleeved on the support rod 211 and connected to the housing 121.

[0098] In other examples, the socket member 122 includes a socket section and two connecting sections. The socket section is connected between the two connecting sections. The socket section and the housing 121 are respectively located on both sides of the support rod 211, and the connecting section is connected to the housing 121 so that the socket member 122 is sleeved on the support rod 211.

[0099] Furthermore, the support rod 211 can be a carbon fiber tube. The carbon fiber tube has a relatively high tensile strength and a relatively light weight, so that the weight of the frame body 210 is relatively light, and thus the weight of the inspection device can be reduced.

[0100] Exemplarily, the frame body 210 is in the shape of a rectangular frame. The number of the support rods 211 and the fixing members 212 is four each, and the support rods 211 form the sides of the rectangular frame.

[0101] It can be understood that the connection manner between the fixing member 212 and the support rod 211 can be snap connection, threaded connection, plug connection, etc.

[0102] In a specific implementation, the fixing member 212 has two fixing holes, and the support rod 211 is inserted into the fixing holes.

[0103] Among them, the fixing holes are matched with the structures of at least part of the support rod 211.

[0104] Exemplarily, the fixing member 212 includes a fixing portion and two connecting portions. The fixing holes are located on the fixing member, and the fixing holes have openings. The two connecting portions are respectively connected to both sides of the opening. The support rod 211 is inserted into the fixing holes, and the two connecting portions are connected to fix the support rod 211 in the fixing holes. Thus, it is more convenient for the support rod 211 to be inserted into and connected to the fixing holes, and at the same time, the size range of the support rod 211 adapted to the fixing holes can be expanded.

[0105] Furthermore, the fixing member 212 further includes at least two plugging members. The support rod 211 is a hollow circular tube, and the fixing holes are through holes. The support rod 211 is inserted into the fixing holes through one end of the fixing holes, and the plugging members can be inserted into the fixing holes through the other end of the fixing holes and inserted into the support rod 211 to support the support rod 211 and prevent damage to the support rod 211 when connecting the two connecting portions of the fixing member 212, resulting in rupture of the support rod 211. At the same time, the ends of the support rod 211 can be plugged to prevent impurities such as dust from entering the support rod 211.

[0106] In a specific implementation, the fixing member 212 has a mounting portion 213, and the lifting structure 300 is connected to the mounting portions 213 of two of the fixing members 212.

[0107] Among them, the second transmission member 320 of the lifting structure 300 is connected to the mounting portions 213 of two fixing members 212 in the same vertical direction, so that the second transmission member 320 is vertically arranged.

[0108] The connection manner between the second transmission member 320 and the mounting portion 213 can be screw or bolt connection, welding, snap connection, bonding, etc.

[0109] Exemplarily, the mounting portion 213 can be a protrusion provided on the fixing member 212.

[0110] In some embodiments, the mounting portion 213 can also be provided on the support rod 211, and the second transmission member 320 of the lifting structure 300 is connected to the support rod 211.

[0111] In some embodiments, the host system 120 further includes a protective housing 123. The protective housing 123 is connected to the housing 121, and at least part of the pressure detection structure 400 is located inside the protective housing 123.

[0112] Among them, the pressure detection structure 400 is connected to the housing 121 to fix the pressure detection structure 400 on the housing 121. By providing the protective housing 123 on the housing 121, the pressure detection structure 400 can be protected by the protective housing 123 to prevent the pressure detection structure 400 from being damaged by external forces, and at the same time prevent rainwater, etc. from contacting the pressure detection structure 400, thereby preventing the pressure detection structure 400 from short-circuiting.
