Description

Technical Field

[0001] The present invention relates to the technical field of power grid disaster prevention and mitigation, and particularly to an automatic grasping and connecting device for a transmission line and an installation method thereof. Background Art

[0002] Disaster risks such as galloping and de-icing jump of transmission lines can cause major accidents such as phase-to-phase flashover tripping and power outage, conductor damage, wire breakage, fitting damage, and tower collapse. It has great harm to the operation of the transmission system, seriously affects the safe operation of the line, and brings huge national economic losses.

[0003] To prevent and control disaster risks such as galloping and de-icing jump of transmission lines, devices such as phase spacers, double pendulum anti-galloping devices, and emergency handling cables need to be installed on the conductors to achieve control of disaster risks. However, how to achieve rapid and reliable connection between the emergency handling device and the line is a current technical problem.

[0004] Since disasters such as galloping and de-icing jump of transmission lines occur in severe weather conditions such as rain, snow, and ice, generally there are no conditions for high-altitude operations where personnel climb towers and go online. Therefore, there is an actual need for an automatic connection device that can work without human climbing.

[0005] Unmanned aerial vehicles (UAVs) play an important role in power-assisted operations. They do not require manual tower climbing or high-altitude operations, shorten the operation time, reduce the labor intensity of personnel, and reduce the risk of high-altitude operations. However, in the construction application of UAV-assisted connection operations, the current connections mainly involve hanging, such as UAV hanging of conductor grounding wires, UAV suspension of safety protection devices for climbing towers, etc. It is difficult to achieve a firm connection at the connection point. If the hanging method is used in the prevention and control of disaster risks such as galloping and de-icing jump of transmission lines, the connection reliability is poor, and during subsequent operation, relative movement may occur between the hanging object and the conductor, resulting in wear problems.

[0020] Unless otherwise required by the context, throughout the specification and claims, the term "comprising" is construed in an open, inclusive sense, i.e., "including, but not limited to". In the description of the specification, the terms "one embodiment", "some embodiments", "exemplary embodiments", "examples" or "some examples", etc. are intended to indicate that the specific features, structures, materials or characteristics related to the embodiment or example are included in at least one embodiment or example of the present disclosure. The schematic representations of the above terms do not necessarily refer to the same embodiment or example. In addition, the specific features, structures, materials or characteristics may be included in any one or more embodiments or examples in any suitable manner.

[0021] An embodiment of the present invention provides an automatic grasping and connecting device for a transmission line and an installation method, as Figure 1 shown, including: a body 1 and a chuck 2.

[0022] In some embodiments, the shape of the body 1 is polygonal.

[0023] Exemplarily, the shape of the body 1 is one of a square, a regular hexagon, and a regular octagon. In actual use, according to the usage scenarios of different split numbers of conductors, the specific shape of the body 1 is selected to form an automatic grasping and connecting device applicable to different conductors such as four-split, six-split, and eight-split. As Figure 1 shown, if the split number of the conductor is four conductors, a four-split automatic grasping and connecting device is used.

[0024] In some embodiments, a plurality of chucks 2 are provided, and the number of the plurality of chucks 2 corresponds to the number of sides of the shape of the body 1. The plurality of chucks 2 are all arranged at the connecting corners of the side of the body 1, and the chuck 2 is hinged to the body 1.

[0025] As Figure 1 shown, Figure 1 is a schematic diagram of a four-split automatic grasping and connecting device, Figure 1 in which the shape of the body 1 is a square, with four sides provided. Correspondingly, four chucks 2 are also provided, and are respectively arranged at the connecting corners of the four sides of the body 1, that is, at the four right angles of the square.

[0026] Exemplarily, as Figure 1 shown, when the automatic grasping and connecting device is in an unused state, the plurality of chucks 2 are folded and arranged on the side of the body 1. When in use, the plurality of chucks 2 rotate and pop out to the side of the body 1 along the Figure 1 direction of the arrow in. In this way, when not in use, the space occupied by the plurality of chucks 2 can be saved, so as to facilitate the high-altitude operation of the automatic grasping and connecting device.

[0027] In some embodiments, the chuck 2 includes a hook portion 21 and a connecting rod structure. The connecting rod structure includes a spring 22, a first slider 23, a second slider 24, and a connecting rod 25. The hook portion 21 is used for connecting with a wire, and the connecting rod structure is used to assist the hook portion 21 in connecting with the wire.

[0028] In some embodiments, the first slider 23 is slidably disposed on the side surface of the chuck 2. The spring 22 is disposed at one end of the first slider 23 and is connected to the first slider 23. The second slider 24 is disposed perpendicular to the hook portion 21, and the second slider 24 is slidably disposed on the hook portion 21. The two ends of the connecting rod 25 are respectively connected to the first slider 23 and the second slider 24.

[0029] Exemplarily, as Figure 2 shown, when the automatic grasping connection device is in an unused state, one end of the spring 22 is connected to the first slider 23, and the other end is connected to the body 1, and the spring 22 is stretched and in an energy storage state. The second slider 24 is disposed on the upper part of the hook portion 21, so that the chuck 2 is in an unclosed state; in the use state, the spring 22 releases energy and changes to a normal non-stretched state, providing power to the first slider 23, and then pulling the first slider 23 to move relative to the chuck 2. After the first slider 23 moves, the second slider 24 is pulled to move through the connecting rod 25, so that the second slider 24 slides towards the hook portion 21, making the chuck 2 in a closed state, and then grasping the wire through the chuck 2 to achieve connection with the wire.

[0030] Since the movement direction of the second slider 24 is perpendicular to the setting direction of the wire, when the wire vibrates due to external factors, the impact force direction of the movement of the second slider 24 is perpendicular to the movement direction of the wire, which can avoid the problem that the chuck 2 is disengaged from the wire due to vibration impact, and thus ensure the stability of the connection between the chuck 2 and the wire.

[0031] An automatic grasping connection device and an installation method for a transmission line provided by the present invention can save the space occupied by multiple chucks through a rotary telescopic chuck structure, so as to facilitate the high-altitude operation of the automatic grasping connection device; through the connecting rod structure of the chuck, the automatic grasping connection device grasps and connects the wire, and at the same time, with the assistance of a drone, the remote control and reliable connection of the automatic grasping connection device are realized.

[0032] An automatic grasping connection device and an installation method for a transmission line provided by the present invention can be widely applied to the installation of different types of transmission line dancing prevention and control devices in the scenario of dancing disaster prevention and control, provide a device and a disposal plan for the rapid and reliable installation of transmission line disaster prevention and mitigation devices, reduce the risk of high-altitude operation, and improve the reliability and efficiency of the operation.

[0033] In some embodiments, the automatic grasping connection device further includes: a first remote control device for releasing the chuck 2 so that the chuck 2 rotates and pops out to the side of the body 1.

[0034] When the automatic grasping connection device is in an unused state, multiple chucks 2 are folded and arranged on the side of the body 1, saving the space occupied by the multiple chucks 2. In the use state, by controlling the first remote control device, the multiple chucks 2 rotate and pop out to the side of the body 1 to facilitate the connection of the chucks 2 to the wire.

[0035] In some embodiments, the automatic grasping connection device further includes: a second remote control device for actuating the link structure so that the second slider 24 slides on the hook portion 21.

[0036] After the automatic grasping connection device reaches the designated operation position by the unmanned aerial vehicle (UAV), by controlling the second remote control device, the second slider 24 slides on the hook portion 21, and then the chuck 2 is in a closed state to facilitate the auxiliary connection of the link structure and the hook portion 21 to the wire.

[0037] In some embodiments, a UAV hanging point is provided at the top of the body 1, and the UAV lifts the body 1 to a high altitude for operation through the UAV hanging point.

[0038] In some embodiments, an external connection point is provided at the bottom of the body 1, and the external connection point connects the body 1 to the emergency disposal device.

[0039] In some examples, the emergency disposal device includes any one of a double pendulum anti-vibration device, an interphase spacer, and a dancing emergency disposal cable.

[0040] As Figures 4-6 shown, they are respectively schematic diagrams of the connection states of the automatic grasping connection device with the double pendulum anti-vibration device, the interphase spacer, and the dancing emergency disposal cable.

[0041] The embodiment of the present invention provides a transmission line automatic grasping connection device and an installation method, including steps: S100 - S500.

[0042] S100, the UAV carries the automatic grasping connection device into the air through the remote disconnection device, aligns the center of the automatic grasping connection device with the center of the bundled conductor, and arranges the plane of the automatic grasping connection device perpendicular to the wire arrangement direction.

[0043] The arrangement directions of multiple bundled conductors are the same. Arranging the plane of the automatic grasping connection device perpendicular to the wire arrangement direction enables the automatic grasping connection device to grasp multiple bundled conductors through multiple chucks, and then separates the multiple bundled conductors from each other to prevent the transmission line from dancing and de-icing jump.

[0044] S200, control the first remote control device to release the ejectable chuck 2.

[0045] When the drone takes off with the automatic grasping connection device, multiple chucks 2 are folded and arranged on the side of the body 1. After the automatic grasping connection device reaches the operation braking position, release the ejectable chuck 2 through the first remote control device to facilitate the connection between the chuck 2 and the wire.

[0046] S300, control the drone to finely adjust the position of the automatic grasping connection device so that the chuck 2 is attached to the bundled conductor. In this way, the accuracy of the chuck grasping the wire can be improved.

[0047] S400, control the second remote control device to slide the second slider 24 to achieve the connection between the chuck 2 and the wire.

[0048] S500, control the remote disconnection device to disconnect the drone from the automatic grasping connection device to complete the installation of the automatic grasping connection device.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solutions of the present invention should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
