[0035] First embodiment

[0036] See also Figures 1 to 12 The present invention provides a multi-split transmission line grounding device, including a drone, a hook 102, a hanging tower assembly 103, a hanging wire assembly 104 and a control rope 105, wherein the hook 102 is connected to the drone, the hanging tower assembly 103 includes a first locking member 106, a second locking member 107 and a support member 108, the support member 108 is connected to the hook 102, the first locking member 106 is used to lock the angle steel by the deadweight of the support member 108 when contacting the angle steel, and the second locking member 107 is used to When the UAV is detached from the hook 102, the angle steel is locked by the self-weight of the hook 102 and the second locking member 107. The hanging wire assembly 104 includes a grounding wire 109, a guide member 110, and a cable self-locking member 111. The grounding wire 109 is connected to the support member 108, and the guide member 110 is connected to the grounding wire 109. The cable self-locking member 111 is arranged on the guide member 110. The control rope 105 bypasses the guide member 110 and passes through the support member 108 to control the position of the guide member 110.

[0037] In this embodiment, the drone serves as a mobile platform for the entire device and is responsible for transporting the hooking device to the designated location. The selection of the drone should take into account its load-bearing capacity and flight stability to ensure that the device can be safely carried and accurately positioned on the high-voltage line tower. The hook 102 is directly connected to the drone and is a key component for achieving the physical connection between the device and the drone. Sufficient mechanical strength should be ensured during the design to withstand the various forces that may occur during the hooking process.

[0038] When the device approaches the angle steel on the transmission tower, the first locking member 106 automatically triggers the locking mechanism by utilizing the deadweight of the support member 108 to ensure that the device can be firmly fixed on the angle steel.

[0039] Once the drone completes its mission and is ready to leave, the second locking piece 107 will use the hook 102 and its own weight to reinforce the locking state. In addition, the hanging wire assembly 104 is connected to the second locking piece 107 through the grounding wire 109, so that the weight of the hanging wire assembly 104 can be added to move downward to further reinforce the locking state of the second locking piece 107 to prevent loosening or falling off due to external factors.

[0040] The grounding wire 109 of the wire hanging assembly 104 serves as a bridge between the tower hanging assembly 103 and the wire hanging assembly 104, and plays the role of transmitting force. The guide member 110 is installed on the grounding wire 109 to guide the cable self-locking member 111 to correctly reach the predetermined position. The cable self-locking member 111 is located on the guide member 110 and is used to quickly and accurately lock the target transmission line to ensure that the hanging and grounding operation is completed smoothly.

[0041] The control rope 105 passes around the guide member 110 and passes through the inside of the support member 108. The operator can accurately control the position of the guide member 110 by adjusting the control rope 105, thereby affecting the working state of the cable self-locking member 111 and achieving the purpose of remote control.

[0042] In summary, this grounding device cleverly combines modern drone technology and traditional mechanical design, which not only greatly improves the safety of power line maintenance work, but also significantly improves work efficiency and reduces costs. It is particularly suitable for power transmission line maintenance under complex terrain conditions.

[0043] The first locking member 106 includes a lifting block 112, a sliding block 113, a connecting rod 114, a first spring 115 and an upper horizontal buckle 116. The lifting block 112 is slidably set on the support member 108, and the sliding block 113 is slidably set on the lifting block 112. One end of the connecting rod 114 is rotatably connected to the support member 108, and the other end of the connecting rod 114 is connected to the sliding block 113. The upper horizontal buckle 116 is fixed to the sliding block 113, and the first spring 115 is connected to the connecting rod 114 and the support member 108.

[0044] The lifting block 112 is a component that can slide vertically on the support member 108. When the device approaches the angle steel, due to gravity, the lifting block 112 will move upward along the support member 108 to prepare for the subsequent locking action. The sliding block 113 is installed on the lifting block 112 and can slide in the horizontal direction.

[0045] One end of the connecting rod 114 is connected to the support 108 through a rotatable joint, allowing the connecting rod 114 to change angle as the sliding block 113 moves; the other end is fixed to the sliding block 113. This design allows the sliding block 113 to slide toward the side close to the angle steel under the limiting action of the connecting rod 114 when the lifting block 112 moves upward, and the upper horizontal buckle 116 is fixed to the sliding block 113. The upper horizontal buckle 116 will move closer to and eventually clamp the angle steel of the transmission tower as the sliding block 113 moves, thus achieving the locking function. The design of the upper horizontal buckle 116 needs to take into account the compatibility with different types of angle steels to ensure that it can be firmly locked regardless of the specifications of the angle steels encountered.

[0046] The first spring 115 is installed between the connecting rod 114 and the support member 108, and plays a role of reset and buffer. When the sliding block 113 is moved by an external force, the first spring 115 will be stretched to store energy; once the external force disappears, the energy released by the spring will push the sliding block 113 back to its original position, and at the same time help the entire locking mechanism return to its initial state.

[0047] The support member 108 is a hollow structure.

[0048] The support member 108 adopts a hollow structure design, which not only reduces the weight of the entire device, but also improves the utilization rate of materials and reduces manufacturing costs. The hollow structure effectively reduces wind resistance while ensuring sufficient mechanical strength through a carefully calculated hole layout, thereby enhancing the stability and wind resistance of the device when operating at high altitudes. In addition, the hollow design also helps to dissipate heat, avoid heat accumulation caused by long-term operation, and extend the service life of the device.

[0049] The support member 108 has a limiting groove 117 , and the hook 102 is located in the limiting groove 117 .

[0050] The support member 108 is also provided with a limit groove 117, which is designed to fix and guide the hook 102. The limit groove 117 is located on one side of the support member 108, and its length and width are customized according to the actual size of the hook 102 to ensure that the hook 102 can slide freely in the groove without falling out. The main function of the limit groove 117 is to limit the movement range of the hook 102 to prevent it from being displaced unnecessarily due to external factors (such as wind force, collision, etc.) during operation, thereby ensuring the stability and reliability of the device during the hanging process.

[0051] The limiting groove 117 is designed to be U-shaped or V-shaped. Such a shape can better wrap the hook 102 , reduce the shaking of the hook 102 in the groove, and facilitate the installation and removal of the hook 102 .

[0052] The second locking member 107 includes a second sliding plate 118, a lower horizontal buckle 119, and a first limiting block 120. The second sliding plate 118 is slidably set on the support member 108 and is connected to the hook 102. The lower horizontal buckle 119 is rotatably set on the support member 108. The first limiting block 120 passes through the lower horizontal buckle 119 and is fixed to the second sliding plate 118 for limiting the lower horizontal buckle 119. The grounding wire 109 is connected to the second sliding plate 118.

[0053] The second sliding plate 118 is slidably disposed on the support member 108 and connected to the hook 102. When the drone is detached from the hook 102, the second sliding plate 118 will slide down along the support member 108 under the action of gravity, and the weight of the hanging wire assembly 104 can be applied to the second sliding plate 118 through the ground wire 109. This design ensures that the second sliding plate 118 can respond quickly and activate the locking mechanism after the drone leaves.

[0054] The lower horizontal buckle 119 is rotatably mounted on the support 108 and can rotate freely within a certain range. When the second sliding plate 118 slides down, the lower horizontal buckle 119 rotates due to gravity and eventually gets stuck on the angle steel of the transmission tower. This design enables the device to be locked immediately after the drone leaves, ensuring the stability and safety of the device.

[0055] The first limit block 120 passes through the lower horizontal buckle 119 and is fixed to the second sliding plate 118, and is used to limit the lower horizontal buckle 119. The design of the first limit block 120 ensures that the lower horizontal buckle 119 will not continue to rotate after being rotated to an appropriate position, thereby achieving a stable locking effect. The position and shape of the first limit block 120 are designed to ensure that there will be no jamming or loosening during the locking process.

[0056] The second locking member 107 also includes a contact mechanism, which is slidably arranged on one side of the second sliding plate and close to the angle steel. During the downward movement of the hanging wire assembly 104 and the grounding wire 109 by their own weight, the contact mechanism is pushed to horizontally press the angle steel to ensure effective grounding contact.

[0057] The contact mechanism includes a guide rail 134, a top tongue 135, a fourth spring 136, a fifth spring 137, a special-shaped slider 138, a latch 139 and a contact panel 140. The guide rail 134 is slidably set on one side of the support member 108, the special-shaped slider 138 is slidably set in the guide rail 134, the fifth spring 137 is set in the special-shaped slider 138, and is used to press the top tongue 135 onto the second sliding plate 118. The contact panel 140 is rotatably set on one side of the guide rail 134 through the latch 139, and the fourth spring 136 is set between the special-shaped slider 138 and the guide rail 134.

[0058] The elastic coefficient of the fifth spring 137 is smaller than that of the fourth spring 136 . In the initial state, the fourth spring 136 is in a natural state, and the fifth spring 137 makes the tongue 135 close to the inclined surface of the second sliding plate 118 .

[0059] During the fixing process of the second self-locking mechanism, the second sliding plate 118 moves downward, and the top tongue 135 is squeezed. Since the elastic coefficient of the fifth spring 137 is smaller than that of the fourth spring 136, the contact mechanism slides outward as a whole, so that the contact panel 140 contacts the angle steel. At this time, the contact panel 140 is automatically deflected by the force, so as to fit the angle steel and form an elastic contact (the fourth spring 136 is further squeezed). This ensures that the contact mechanism is in effective contact.

[0060] The guide member 110 includes a guide rod 121 and a guide plate 122 . The guide rod 121 is fixed to the bottom of the guide plate 122 . There is an inclination angle between the guide rod 121 and the guide plate 122 .

[0061] The guide rod 121 is fixed to the bottom of the guide plate 122, and is used to contact the cable to be connected and guide the moving path of the cable self-locking member 111. The guide plate 122 forms a certain inclination angle with the guide rod 121. This inclination angle design helps the cable self-locking member 111 to slide to the predetermined position more smoothly under the action of gravity, and also increases the stability and reliability of the system.

[0062] The control rope 105 includes a control rope body 123, a traction rope 124 and an annular magnet 125, one end of the traction rope 124 is connected to the drone, and the other end of the traction rope 124 is connected to the annular magnet 125, the annular magnet 125 is magnetically attracted to the support member 108, and the control rope body 123 passes through the annular magnet 125 and is connected to the guide member 110 through an electric fixed pulley.

[0063] The control rope body 123 passes through the annular magnet 125 and is connected to the guide member 110 for transmitting operation instructions. The control rope body 123 needs to have high strength and flexibility to ensure that it will not break or get stuck when transmitting instructions.

[0064] One end of the traction rope 124 is connected to the drone, and the other end is connected to the annular magnet 125. A camera module can be set on the drone to monitor the position of the guide member 110. Through the operation of the drone, the position of the control rope body 123 can be adjusted, so that after the cable is grounded, the drone can be started to drive the traction rope 124 and the annular magnet 125 to detach from the support member 108, thereby driving the control rope body 123 to detach from the guide member 110. In addition, an electric control latch can be set on the support member 108, and the electric control latch can be loosened through remote control so that the traction rope 124 is not connected to the tower hanging device and fixedly connected. After the electric control latch is opened, the traction rope 124 connected to the hook 102 can pull the annular magnet 125 to drive the traction rope 124 to be towed and recovered by the drone. Note: When the electric control latch of the tower hanging device cannot be remotely controlled to detach under abnormal conditions, the traction rope 124 can be cut off at the ground end to allow the drone to return with the traction rope 124 and the annular magnet 125.

[0065] For details, please refer to Figure 4 After the tower hanging assembly 103 is hung on the angle steel (the wire hanging assembly 104 has not yet been hung on the wire), the tower hanging assembly 103 is clamped by gravity self-locking, and the electric fixed pulley plays the role of a pulley.

[0066] The wire hanging assembly 104 hangs the wire. Because the actual distance between the angle steel of the overhead line tower and the wire is different (depending on the voltage level, environmental climate and other factors, the distance difference is very large), when the tower hanging assembly 103 is fixed, the wire hanging assembly 104 is below the wire. Personnel B pulls the traction rope 124 on this side to make the wire hanging device rise and higher than the wire. Personnel A then pulls the other side of the traction rope to fix the wire hanging device on the wire.

[0067] The guide member 110 has a wire clamping mechanism 126 , and the control rope body 123 passes through the wire clamping mechanism 126 and can slide around the wire clamping mechanism 126 .

[0068] The clamping mechanism 126 is located on the guide member 110 and is used to fix and guide the control rope body 123. The design of the clamping mechanism 126 needs to take into account the sliding performance of the control rope body 123 to ensure that there will be no jamming or wear during operation. The clamping mechanism 126 can be provided with a locking structure to lock the passing cable to maintain the position, or release it so that the cable can be detached.

[0069] The cable self-locking part 111 includes a contact slider 127, a second spring 128, a third spring 129, a pull rod 130, an intermediate rod 131, a second limit block 132 and a rotating baffle 133. The contact slider 127 is slidably set on the guide plate 122. The second spring 128 is used to support the contact slider 127. The rotating baffle 133 is rotatably set on one side of the contact slider 127. The second limit block 132 is slidably set at the bottom of the rotating baffle 133 for limiting the rotating baffle 133. The pull rod 130 is connected to the guide plate 122 through the third spring 129. The intermediate rod 131 is connected to the pull rod 130 and the second limit block 132.

[0070] The contact slider 127 is slidably disposed on the guide plate 122 for contacting and locking the power line. The design of the contact slider 127 needs to ensure that it slides smoothly on the guide plate 122 and has sufficient friction so that it can firmly grasp the cable when contacting the power line.

[0071] The second spring 128 is used to support the contact slider 127. When the contact slider 127 does not contact the transmission line, the second spring 128 keeps it in the initial position. Once the contact slider 127 contacts the cable, the contact slider 127 moves upward and the second spring 128 is compressed to store the restoring force.

[0072] The rotating blocking rod 133 is rotatably disposed on one side of the contact slider 127 and can rotate freely within a certain range.

[0073] The second limiting block 132 is slidably disposed at the bottom of the rotating blocking rod 133 to limit the rotating blocking rod 133 .

[0074] The pull rod 130 is connected to the guide plate 122 through the third spring 129. The main function of the pull rod 130 is to provide force when locking is required to help the second limiting rod limit the rotation blocking rod 133.

[0075] The third spring 129 connects the pull rod 130 and the guide plate 122 to provide a reset force. When the pull rod 130 is pulled, the third spring 129 will reset from the compressed state to release energy. The intermediate rod 131 is connected to the pull rod 130 and the second limit block 132 to transmit force. The design of the intermediate rod 131 ensures that the force of the pull rod 130 can be effectively transmitted to the second limit block 132, thereby controlling the locking and unlocking action of the rotating block rod 133. The material selection of the intermediate rod 131 needs to have good strength and rigidity to ensure that it will not deform or break during the force transmission process.

[0076] Specifically, during clamping, the cable first contacts the contact slider 127 so that under the action of gravity, the contact slider 127 moves upward relative to the guide plate 122. At this time, the contact slider 127 releases the limit on the rotating baffle 133, so that under the support of the third spring 129, the pull rod 130 moves downward, so that the middle rod 131 drives the second limit block 132 to slide to push the rotating baffle 133 to rotate to enclose the cable for fixing the cable.

[0077] When unlocking, the drone provides an upward pulling force, and the cable pushes the rotating lever 133 downward, so that the rotating lever 133 can push the second limit block 132 backward, so that the rotating lever 133 can rotate, and at the same time, the contact slider 127 moves downward under the support of the second spring 128 to limit the rotating lever 133, so that the cable can be pulled out of the guide plate 122.

[0080] The S201 drone drives the entire device to the location of the cables and angle steel via the hook 102;

[0081] The operator first starts the drone and launches it into the air using a remote controller or a preset route. The drone carries the entire grounding device and is connected to the device via a hook 102. The operator controls the drone to gradually approach the transmission tower until the device is directly above the cables and angle steel. Using the drone's camera and sensors, the operator can monitor the location of the device in real time to ensure that it is accurately aligned with the target location.

[0082] S202 The tower assembly 103 contacts the angle steel, and the first locking member 106 locks the angle steel in the horizontal direction;

[0083] When the drone moves the device to the designated position, the support member 108 in the tower assembly 103 first contacts the angle steel of the transmission tower. The weight of the support member 108 causes the lifting block 112 to slide down along the support member 108, thereby pushing the sliding block 113 to move horizontally. The movement of the sliding block 113 drives the angle change of the connecting rod 114, and finally the horizontal buckle clamps the angle steel to achieve horizontal locking. The operator confirms through the drone's camera that the first locking member 106 has successfully locked the angle steel to ensure the initial stability of the device.

[0084] S203 The drone moves downward so that the tower assembly 103 is completely supported by the angle steel. At this time, the hook 102 and the second support member 108 push the second locking member 107 to move under the action of gravity to lock the angle steel in the longitudinal direction;

[0085] The operator controls the drone to slowly descend so that the tower assembly 103 is fully supported by the angle steel. At this time, the second sliding plate 118 slides down along the support member 108 under the action of gravity. The sliding of the second sliding plate 118 pushes the lower horizontal buckle 119 to rotate, causing it to jam the angle steel. The first limit block 120 ensures that the lower horizontal buckle 119 is locked in the appropriate position to prevent it from continuing to rotate. The operator once again confirms through the drone's camera that the second locking member 107 has successfully locked the angle steel to ensure the stability of the device in the longitudinal direction.

[0086] S204 The ground operator pulls the control rope 105 to make the guide member 110 of the wire hanging assembly 104 close to the cable, and the cable self-locking member 111 clamps the wire and self-locks to complete the grounding.

[0087] The ground operator pulls the traction rope 124 through the control rope body 123, and the traction rope 124 transmits force through the annular magnet 125, so that the guide rod 121 and the guide plate 122 of the guide member 110 are close to the transmission line. The wire clamping mechanism 126 of the guide member 110 ensures that the control rope body 123 slides smoothly when transmitting force, so that the guide rod 121 and the guide plate 122 are accurately aligned with the transmission line. The contact slider 127 slides on the guide plate 122, and after contacting the transmission line, the second spring 128 is compressed to provide downward force. The rotating baffle 133 rotates due to the resistance of the transmission line, further locking the transmission line. The second limit block 132 slides to the bottom of the rotating baffle 133 to ensure that it is locked in the appropriate position. The operator confirms through the camera of the drone or the ground sensor that the cable self-locking member 111 has successfully clamped the transmission line and self-locked, completing the grounding operation.

[0088] After the grounding is completed, the drone controls the traction rope 124 to electrically detach, so that the drone flies away carrying the traction rope 124.

[0089] After the line construction work is completed, the drone is controlled to hook the hook 102 carried by the drone onto the support 108, so that the support 108 receives an upward pulling force to mechanically unlock the tower hanging assembly 103, thereby completing the unlocking of the tower hanging device at the pole tower end;

[0090] The drone continues to extract the tower hanging assembly 103 upward, and the upward pulling force is transmitted to the hanging wire assembly 104 through the grounding wire, so that the hanging wire assembly 104 is mechanically unlocked.

[0091] What is disclosed above is only a preferred embodiment of the present invention, and it certainly cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made according to the claims of the present invention still fall within the scope of the invention.
