Description

Technical Field

[0001] The invention relates to a power transmission overhead line deicing device matched with an unmanned aerial vehicle, and belongs to the field of power line fault inspection and maintenance. Background Art

[0002] Transmission line icing is a serious natural disaster. Severe icing is likely to cause transmission line failure, which will lead to catastrophic accidents such as large-scale power outages. For example, if the ice on the conductors and lightning conductors falls off locally, the loads on the conductors will be uneven, which will cause the conductors to jump and collide. In addition, under the influence of icing, the conductors will sag, and the distance between the conductors and the ground will decrease. At the same time, the poles and towers are subjected to excessive loads due to the icing on the conductors, which may easily cause pole or tower collapse accidents. In addition, icing on transmission lines increases the possibility of overhead lines dancing. When the conductors dance, they will damage the poles, towers, conductors, hardware and components, causing frequent tripping and even power outages. The conductors mentioned here are overhead lines and transmission cables.

[0003] The existing announcement number is CN 217115548U, and the name of the patent application is a fixed outdoor cable deicing device, which reveals that it uses vibration to knock down water droplets and ice cubes on the cable to avoid personnel from performing high-altitude deicing operations. However, the transmission lines and high-voltage lines are at least 8-10 meters away from the bottom surface. Different from household electricity, they are high-altitude operations. The use of this fixed outdoor cable deicing device is not only troublesome to install and time-consuming, but also difficult to recycle. In emergency situations, such as blizzards, it cannot be used at all.

[0004] The existing announcement number is CN115800164B, and the name of the patent application is "A deicing device and deicing method for a power line ground wire deicing robot", which discloses that the deicing device can realize two-way operation on the power line ground wire, and the deicing hammer can be raised or lowered or rotated by the power mechanism to a height or angle that does not hinder the deicing robot from going online before going online, and the deicing method is mainly knocking, supplemented by rolling and cleaning, and the ice residue remaining on the power line ground wire is cleaned at the same time, and a camera is used to monitor the ice coverage of the power line ground wire and the deicing condition of the deicing device, which also does not have the advantage of quick disassembly and assembly, and the deicing method is mainly knocking, supplemented by rolling and cleaning, but from the present application Figure 1 It can be seen that the gravity of the entire device of the present application is biased to one side. During actual use, it is easy to lose balance, causing the wires to twist. For high-voltage lines, the insulating paper will wrinkle, loosen, or even break, causing current leakage and safety accidents.

[0005] The existing announcement number is CN110588976A, and the name of the patent application is a high-altitude cable deicing drone. It reveals that a driving deicing structure is set on the inside of the claw structure, and the drone is fixed on the cable as a whole. That is, the drone and the deicing device need to work synchronously and cannot be separated. In extreme rainy and snowy weather, the drone cannot work normally due to the influence of low temperature and rain and snow.

Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0048] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0049] Reference Figure 1 As shown, this embodiment provides a specific implementation method for a power transmission overhead line deicing device equipped with a drone, which uses a drone to fix the power transmission overhead line deicing device on the overhead line or separate it from the overhead line, including: a hinged frame 10, which is used to be erected on the overhead line and move on the overhead line; a deicing unit 20 is installed on the hinged frame 10, and is used to remove ice on the overhead line when the hinged frame 10 is fixed on the overhead line.

[0050] Furthermore, the unmanned aerial vehicle pulls the power transmission overhead line deicing equipment to move on the overhead line, and adjusts the placement position of the present invention on the overhead line.

[0051] The present invention adopts a split design of a drone and a hinged frame 10, adopts a drone bracket to operate the hinged frame 10, allows the hinged frame 10 to be hung on the overhead line, and the deicing unit 20 then cleans the ice on the overhead line. The drone is only used during installation or disassembly and does not need to work continuously. It has high flexibility in use and a wide range of applications.

[0052] Among them, the structure and principle of the hinged rack 10: the hinged rack 10 includes a cylinder 101, a first loose-leaf bracket 102 and a second loose-leaf bracket 103, the cylinder 101 is parallel to the transmission direction of the overhead line, and the first loose-leaf bracket 102 and the second loose-leaf bracket 103 are rotatably connected on both sides of the cylinder 101 along the long side direction, so that when the cylinder 101 contacts or separates from the overhead line, the first loose-leaf bracket 102 and the second loose-leaf bracket 103 can be combined to wrap and fix the overhead line or separate.

[0053] That is, when the present invention is installed, the hinged frame 10 is operated by a drone. When the cylinder 101 contacts the overhead line, the drone continues to lower the height, and the first and second hinged frames 102 and 103 continue to fall under the action of their own gravity. Because of the magnets, they are directly positioned and attracted. The magnets are shown below. While wrapping the overhead line, the hinged frame 10 is also fixed on the overhead line.

[0054] Furthermore, the cylinder 101 includes an arc-shaped bracket 111, and the arc-shaped bracket 111 is a semi-cylinder with open ends;

[0055] The pulley block 112 and the traction rope 113 are fixed to the inner wall at the center of the arc-shaped bracket 111. The number of the traction rope 113 is one. The center of the arc-shaped bracket 111 facing the pulley block 112 is provided with an opening 114 for the traction rope 113 to pass through.

[0056] A towing rod 115, one end of which is rotatably connected to the end of the arc-shaped bracket 111, and the other end of which is fixed to the head end or the tail end of the towing rope 113 passing through the opening 114;

[0057] The lifting and traction rope 113 can separate the first loose-leaf support 102 and the second loose-leaf support 103 .

[0058] In one specific embodiment, the pulley block 112 includes a plurality of pulleys 112 - 1 and a frame 112 - 2 for fixing the pulleys. The plurality of pulleys 112 - 1 are horizontally and equidistantly arranged on the same line. The frame 112 - 2 is mounted on the inner wall at the center of the arc-shaped bracket 111 .

[0059] In one specific embodiment, the traction rope 113 is provided with a limit rod 117 on the outer side of the arc-shaped bracket 111, and the limit rod 117 is fixed on the handle to facilitate the connection and lifting of the drone. A hole is provided in the middle of the limit rod 117 to facilitate the passage of the traction rope 113. The length of the limit rod 117 is longer than the opening 114, and the limit rod 117 does not fit into the opening 114. It is flexible and convenient to use, and the height of the increase does not need to be too high. As long as the first loose-leaf bracket 102 and the second loose-leaf bracket 103 can be separated, the overhead line can be left.

[0060] In one specific embodiment, a fixed wire guide 118 is further provided at the contact point between the long side of the arc-shaped bracket 111 and the traction rope 113. The fixed wire guide 118 is used to guide the traction rope 113, directly reducing the friction between the traction rope 113 and the long side of the arc-shaped bracket 111, which will save effort when pulling the traction rope 113 to separate the first loose-leaf bracket 102 and the second loose-leaf bracket 103.

[0061] Furthermore, the cylinder 101 further includes support members 116 fixed at both ends along the long sides, and the support member 116 includes a fixing plate 116-1, and the fixing plate 116-1 is locked on the inner wall of the cylinder 101 by screws;

[0062] Support buckles 116 - 2, 2 in number, are vertically mounted at both ends of the fixing plate 116 - 1 along the width direction, and the ends are rotatably connected to the first loose-leaf bracket 102 or the second loose-leaf bracket 103;

[0063] There are several cylindrical roller bearings 116-3, which are penetrated by the bearing rod 116-4 in the middle and fixed at the head end of the two support buckles 116-2 close to the inner wall of the cylinder 101. The cylindrical roller bearings 116-3 are in contact with or separated from the overhead wire. The cylindrical roller bearings 116-3 have a large radial load capacity and are suitable for bearing heavy loads and impact loads, as well as high-speed rotation.

[0064] When the overhead wire is embedded in the gap between two adjacent cylindrical roller bearings 116 - 3 , the cylindrical roller bearings 116 - 3 will be locked;

[0065] When the trolley wire is in linear contact with the side of the cylindrical roller bearing 116-3, the cylindrical roller bearing 116-3 can be used for sliding.

[0066] In one specific embodiment, the end of the support buckle 116-2 is horizontally tilted downward to form an acute angle with the horizontal line, expanding the support buckle 116-2 outward. When the cylindrical roller bearing 116-3 contacts the overhead line, the expansion and merging of the first loose-leaf bracket 102 and the second loose-leaf bracket 103 will not cause movement interference.

[0067] Furthermore, the first loose-leaf support 102 or the second loose-leaf support 103 includes a horizontal portion 121 along the long side direction and a vertical portion 122 along the wide side direction, and the horizontal portion 121 and the vertical portion 122 are an integrated structure;

[0068] It also includes a hanging ear 133, which is arranged on the side of the head end of the vertical part 122. The hanging ear 133 is rotatably connected to the end of the supporting buckle 116-2 through a rotating shaft to facilitate the expansion or closure of the first loose-leaf bracket 102 and the second loose-leaf bracket 103.

[0069] The structure and principle of the de-icing unit 20 are as follows: there are two de-icing units 20, which are installed on the first loose-leaf bracket 102 or the second loose-leaf bracket 103 of the hinged frame 10, and are distributed symmetrically about the center of the hinged frame 10. On the same line, the two de-icing units 20 rotate and vibrate synchronously, causing line resonance, and the de-icing effect is better.

[0070] The deicing unit 20 includes a battery box 201, a driving unit 202, a deicing head 203, and a housing 204. The housing 204 includes a second horizontal portion 241 on the same horizontal line as the battery box 201 and a second vertical portion 242 vertical to the second horizontal portion 241.

[0071] A de-icing head 203 is installed at the end of the second vertical portion 242, and the de-icing head 203 is in contact with or separated from the overhead line. A driving unit 202 is installed on the housing 204 between the de-icing head 203 and the battery box 201, and the driving unit 202 is electrically connected to the power supply inside the battery box 201, so that the driving unit 202 can drive the de-icing head 203 to operate normally.

[0072] Furthermore, magnets 205 are installed on the sides of the two battery boxes 201 that are in movable contact, which facilitates positioning when the first loose-leaf bracket 102 or the second loose-leaf bracket 103 contacts the overhead line and closes, and ensures that the closure is tight after the first loose-leaf bracket 102 or the second loose-leaf bracket 103 is closed and contacted, and will not be easily separated by external force.

[0073] In one specific embodiment, the thickness L1 of the battery box 201 is half the thickness L2 of the second horizontal portion 241 of the outer shell 204. When the first loose-leaf bracket 102 or the second loose-leaf bracket 103 carries the de-icing unit 20 and is put together and tightly fitted, the outer surface is flat and installed on both sides of the overhead line. The gravity on both sides is balanced, which will not cause excessive twisting of the overhead line and rupture of the outer insulation skin.

[0074] Furthermore, the driving unit 202 includes a rotating module 222, the rotating module 222 includes a motor 222-1, and the motor 221 is mounted on the second horizontal portion 241 of the housing 204 through a motor bracket 2221, close to the battery box 201 and electrically connected to the battery box 201;

[0075] A rotating rod 222-2, wherein the rotating rod 222-2 is vertically mounted in the middle of the second vertical portion 242 through the other end of the motor bracket 2221, and the upper and lower ends of the rotating rod 222-2 are in contact with the inner wall of the housing 204 through deep groove ball bearings 222-3, and the other end of the rotating rod 222-2 that is not connected to the motor bracket 2221 is equipped with a deicing head 203;

[0076] The speed changing unit 222-4 is used for mechanical transmission between the output end of the motor 222-1 and the rotating rod 222-2. The speed changing unit 222-4 changes the transmission ratio and reduces the torque, making the transmission of the de-icing head 203 simpler.

[0077] Furthermore, the speed change unit 222-4 includes a first gear 222-5, a second gear 222-6, a third gear 222-7, and a fourth gear 222-8, wherein the first gear 222-5 is mounted on the output end of the motor 222-1, and the first gear 222-5 is meshed with the second gear 222-6;

[0078] The fourth gear 222-8 is installed at the end of the rotating rod 222-2 close to the motor bracket 2221, the third gear 222-7 is located in the middle of the second horizontal portion 241, and the third gear 222-7 and the fourth gear 222-8 are vertically meshed;

[0079] The third gear 222-7 and the second gear 222-6 are fixed by a shaft;

[0080] The output end of the motor 222 - 1 can be transmitted to the fourth gear 222 - 8 , thereby driving the rotating rod 222 - 2 to rotate, so that the de-icing head 203 can rotate.

[0081] The de-icing head 203 includes a fan blade 231 and an impact head 232 . The impact head 232 can extend or retract in the middle of the fan blade 231 .

[0082] In one specific embodiment, the free end of the impact head 232 exposed outside the wind blade 231 is bullet-shaped. When it comes into contact with ice on the overhead line, the contact area is small and the pressure is high, so the ice can be easily broken.

[0083] In one specific embodiment, the driving unit 202 of the present invention further includes an impact module 221, and the impact module 221 includes a cylinder 221-1. The fixed end of the impact head 232 passes through the middle of the rotating rod 222-2 and is mechanically connected to the cylinder 221-1.

[0084] It also includes a crank 221 - 2 and a turntable 221 - 3 , wherein one end of the crank 221 - 2 is rotatably connected to the cylinder 221 - 1 , and the other end is rotatably connected to a position of the turntable 221 - 3 that is offset from the center of the circle.

[0085] It also includes a fifth gear 221-4, which is on the same horizontal plane as the first gear 222-5, and the first gear 222-5 is meshed with the fifth gear 221-4, and the fifth gear 221-4 is connected to the center of the turntable 221-3 through a connecting rod.

[0086] The present invention can control the extension and retraction of the impact head 232 by energizing the cylinder 221-1, and can also drive the cylinder 221-1 to move forward and backward through the operation of the motor 222-1, thereby driving the extension and retraction of the impact head 232. The extension and retraction of the impact head 232 will impact the ice on the overhead line at high speed.

[0087] As a possible specific implementation of the present invention, the impact head 232 is made of silicone rubber material. Silicone rubber refers to a rubber whose main chain is composed of alternating silicon and oxygen atoms, and the silicon atom is usually connected to two organic groups. It has good high and low temperature resistance, good electrical properties, oil and chemical reagent resistance, aging resistance, and low hardness, and will not scratch the circuit.

[0088] As a possible specific implementation of the present invention, a wireless module is provided inside the battery box 201 or the housing 204 of the de-icing unit 20. The wireless module refers to a high-performance professional data transmission radio module realized by means of DSP technology and radio technology to control the stepless speed change of the motor 222-1, change the speed change frequency and the impact frequency, so as to trigger line resonance and achieve maximum de-icing.

[0089] In summary, the deicing unit 20 of the present invention has both a rotary deicing function and an impact function. In actual use, multiple devices can be installed on each overhead line using a drone, about one device every 100-200 meters, and set to work for 1 minute every 5 minutes. The battery built into the battery box 201 can ensure 2 days of work. When there is a freezing forecast or a heavy snow report, layout in advance and vibration in time to avoid ice formation.
