Description

Technical Field

[0001] This utility model relates to the field of line maintenance technology, and in particular to a de-icing device for power transmission and transformation lines. Background Technology

[0002] Cables are core components of power transmission lines and are an indispensable infrastructure in modern society's power, communication, and energy sectors. They transmit electrical energy or signals through conductors, offering advantages such as high transmission efficiency, low loss, and high reliability. In low-temperature environments such as rain or snow, cable surfaces are prone to icing. This icing increases cable resistance, reducing power transmission efficiency, increasing energy consumption, and can even lead to cable overload and breakage, causing power outages and affecting the stability of power supply. Therefore, timely de-icing of cables is necessary. Existing de-icing methods generally involve manual de-icing or using equipment to break up the ice on the cable. However, manual de-icing is labor-intensive, and the slippery surface of icy cables poses a risk of accidents. Furthermore, knocking on the cable to remove ice can easily damage the cable surface due to excessive force, limiting its effectiveness. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned shortcomings by providing a de-icing device for power transmission and transformation lines, enabling stable and safe de-icing of cables.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a de-icing device for power transmission and transformation lines, comprising a drone and a heating module;

[0005] The bottom of the drone is equipped with a universal swing assembly, and the moving end of the universal swing assembly is equipped with a heated de-icing mechanism. The universal swing assembly is used to make the heated de-icing mechanism surrounding the line swing universally with the line.

[0006] The heated de-icing mechanism includes a spacing adjustment component, which has two movable ends that can move closer to or further away from each other. Each of the two movable ends is provided with a C-shaped frame, and a C-shaped heated ring is rotatably provided in each of the two C-shaped frames. The two heated rings are combined to form a ring.

[0007] A drive device, used to drive the heated ring to rotate around the center point of the C-shaped frame;

[0008] An anti-detachment component, which is mounted on a C-shaped frame, is used to prevent the heated ring from falling out of the C-shaped frame;

[0009] The emitter of the heating module faces the heating ring.

[0010] Furthermore, the omnidirectional swing assembly includes a sleeve disposed at the bottom of the drone, a ball sleeve rod slidably inserted into the sleeve, and a ball rod rotatably disposed at the bottom of the ball sleeve rod. A fixing member is provided on the sleeve, which is used to fix the ball sleeve rod in the sleeve.

[0011] Furthermore, the pitch adjustment assembly includes a platform disposed at the bottom of the cue stick, wherein a lead screw with two oppositely oriented threads is rotatably disposed in the platform, and a first motor is disposed on the platform to drive the lead screw to rotate.

[0012] Furthermore, the heated de-icing mechanism also includes mounting platforms disposed at the corresponding two threaded sections of the lead screw and threadedly engaged therewith. Each of the C-shaped frames is connected to the corresponding mounting platform. The driving device includes a half-tooth ring disposed on each of the heated rings, a second motor disposed on the corresponding C-shaped frame, and a gear disposed at the moving end of the second motor. The gear meshes with the corresponding half-tooth ring.

[0013] Furthermore, the anti-detachment component includes a C-shaped groove formed in each of the heating rings, and each of the C-shaped frames is provided with an anti-detachment rod inserted into the corresponding C-shaped groove. Both ends of the C-shaped heating ring are provided with a set of contacts, and the C-shaped frame is provided with another set of contacts corresponding to the contacts on the heating ring.

[0014] Furthermore, an opening is provided on the side wall of the C-shaped frame.

[0015] Furthermore, the heating module is a laser module, with the emitting end of the laser module facing the opening, and the laser module emits a laser beam onto the heating ring for heating the heating ring.

[0016] Furthermore, a mounting frame is provided at the bottom of the mounting platform, and the heating module is vertically mounted on the mounting frame with the emitting end of the heating module facing the opening.

[0017] Furthermore, it also includes a ground engineering vehicle, on which a position recognition module is installed, and the heating module is installed on the ground engineering vehicle. The position recognition module is used to identify the C-shaped frame with an opening, so that the emitting end of the heating module faces the opening.

[0018] The beneficial effects of this utility model are reflected in:

[0019] In this invention, the operator activates the heating module and launches a drone. The heated rings are heated, and the drone flies and approaches the cable until it is positioned between the two heated rings. Then, the spacing adjustment component drives the two C-shaped frames closer together, causing the two heated rings to surround the cable. If the ice layer on the cable is thick, the heated rings, having been preheated, can melt the ice simultaneously upon approaching the cable. Once the two C-shaped frames are in contact, the drive device is activated, causing the two heated rings to rotate around the midpoint of the C-shaped frames. During this process, different arc surfaces of the heated rings are heated by the heating module, resulting in simultaneous temperature increases at different locations. The heated rings are then placed on the cable, melting the ice layer. This de-icing method does not damage the cable surface and provides a very stable de-icing operation, making it convenient for practical use. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0030] Please see Figure 1-7 This utility model discloses a de-icing device for power transmission and transformation lines, including a drone 1 and a heating module 5. The bottom of the drone 1 is provided with a universal swing assembly 2, and the moving end of the universal swing assembly 2 is provided with a heated de-icing mechanism 3. The universal swing assembly 2 is used to make the heated de-icing mechanism 3 surrounding the line swing universally with the line. The drone 1 includes a body 11 and a base frame 12 installed at the bottom of the body 11. The drone 1 belongs to the well-known technology in this field, so its specific structural composition and working principle will not be described in detail in this article.

[0031] In one embodiment, the heated de-icing mechanism 3 includes a spacing adjustment component 31, which has two movable ends that can move closer to or further away from each other. Each of the two movable ends is provided with a C-shaped frame 33, and a C-shaped heated ring 34 is rotatably installed in each of the two C-shaped frames 33. The two heated rings 34 are combined to form a ring. The device also includes a driving device and an anti-detachment component. The driving device is used to drive the heated ring 34 to rotate around the midpoint of the C-shaped frame 33, while the anti-detachment component is provided on the C-shaped frame 33 to prevent the heated ring 34 from falling out of the C-shaped frame 33. The emitting end of the heating module 5 is directed toward the heated ring 34.

[0032] In practice, the staff activates the heating module 5 and launches the drone 1. At this time, the heated ring 34 is heated, and the drone 1 flies into the air and approaches the cable until the cable is between the two heated rings 34. Then, the spacing adjustment component 31 drives the two C-shaped frames 33 to approach each other, so that the two heated rings 34 inside surround the cable. If the ice layer on the cable is thick, since the heated rings 34 have been heated beforehand, the ice layer can be melted simultaneously when they approach the cable. When the two C-shaped frames 33 come into contact with each other, the drive device is activated, so that the two heated rings 34 rotate around the midpoint of the C-shaped frame 33 and inside the C-shaped frame 33. During this process, different arc surfaces of the heated rings 34 are heated by the heating module 5, so that different positions of the heated rings 34 are heated synchronously. The heated rings 34 are then placed on the cable, thereby melting the ice layer on the cable. This method of de-icing will not damage the cable surface and can perform de-icing operations very stably, thus facilitating practical use.

[0033] Understandably, when the two heated rings 34 rotate and shift within the corresponding C-shaped frame 33, the anti-detachment component cooperates with the heated rings 34 to prevent them from falling out of the C-shaped frame 33, thereby ensuring operational safety. In practice, a temperature monitoring element (such as a temperature sensor) can be installed on the heated rings 34. The installed temperature monitoring element is not within the irradiation range of the heating module 5, which is used to ensure that the temperature of the heated rings 34 is within a suitable range, so as to melt the ice layer without damaging the cable. Since the cable will produce ice cones when it freezes, when the drone 1 moves the heated de-icing mechanism 3 on the cable, the side of the heated rings 34 will come into contact with the ice cones, thereby heating and removing the ice cones.

[0034] In one embodiment, the omnidirectional swing assembly 2 includes a sleeve 21 mounted on the bottom of the drone 1, a ball sleeve rod 22 slidably inserted into the sleeve 21, and a ball rod 23 rotatably mounted on the bottom of the ball sleeve rod 22. A fixing member is provided on the sleeve 21 to fix the ball sleeve rod 22 in the sleeve 21.

[0035] In practice, since the cable is at a high altitude, it will sway with the wind. Therefore, when the cable sways, the heated de-icing mechanism 3 will also sway, causing the ball rod 23 to swing with the same amplitude as the connection point with the ball sleeve rod 22. This process reduces the impact on the ball sleeve rod 22, thereby improving the working safety of the UAV 1. Furthermore, the ball sleeve rod 22 and the sleeve body 21 are telescopically adjustable in length. After adjustment, they can be positioned by fixing parts, which can be pins. The ball sleeve rod 22 and the sleeve body 21 have multiple interlocking locking holes, which, in conjunction with the pins, allow the ball sleeve rod 22 and the sleeve body 21 to be adjusted to different lengths. This design allows the distance between the UAV 1 and the heated de-icing mechanism 3 to be adjusted according to actual needs, thus facilitating practical use.

[0036] In one embodiment, the pitch adjustment assembly 31 includes a platform 311 mounted on the bottom of the cue stick 23, a lead screw 312 with two oppositely oriented threads rotatably mounted in the platform 311, and a first motor 313 mounted on the platform 311 to drive the lead screw 312 to rotate.

[0037] With this design, when the first motor 313 starts, the lead screw rotates 312 accordingly, which is used to drive the two C-shaped frames 33 to move closer to or further away from each other.

[0038] In one embodiment, the heated de-icing mechanism 3 further includes a mounting platform 32 disposed at the corresponding two threaded sections of the lead screw 312 and threadedly engaged therewith. Each C-shaped frame 33 is connected to the corresponding mounting platform 32. The driving device includes a half-gear ring 37 mounted on each heated ring 34, a second motor 38 mounted on the corresponding C-shaped frame 33, and a gear 39 mounted on the moving end of the second motor 38. The gear 39 meshes with the corresponding half-gear ring 37.

[0039] With this design, when the second motor 38 starts, the gear 39 rotates and drives the half-gear ring 37 that meshes with it to rotate. The two heated rings 34 rotate synchronously, and the two half-gear rings 37 combine to form a complete gear ring, thus cooperating with the gear 39 and rotating continuously.

[0040] In one embodiment, the anti-detachment component includes C-shaped grooves 35 formed in each heating ring 34, and anti-detachment rods 36 inserted into the corresponding C-shaped grooves 35 are detachably installed on each C-shaped frame 33. A set of contacts 6 is installed at both ends of the C-shaped heating ring 34, and another set of contacts 6 (not shown in the figure) corresponding to the contacts 6 on the heating ring 34 is installed on the C-shaped frame 33.

[0041] In practice, when the heated ring 34 rotates, the anti-detachment rod 36 is always in the C-groove 35 on the corresponding heated ring 34, so that the heated ring 34 will not detach from the C-shaped frame 33. The device is equipped with a controller that cooperates with the contact 6. The controller is connected to the second motor 38. When it is necessary to stop heating the cable, the contact 6 on the heated ring 34 needs to contact the contact 6 on the corresponding C-shaped frame 33 to form a circuit. This circuit connects the controller and causes the controller to stop the second motor 38, so that each heated ring 34 is in the corresponding C-shaped frame 33 to ensure safe separation.

[0042] It should be noted that, in practice, the length of the anti-detachment rod 36 is no less than half the width of the heated ring 34. This design ensures that the heated ring 34 will not be higher at one end and lower at the other when rotating, thus ensuring the safety of the heated ring 34 during rotation.

[0043] In one embodiment, an opening 4 is provided on the side wall of the C-shaped frame 33.

[0044] In one embodiment, the heating module 5 is a laser module, with the emitting end of the laser module facing the opening 4. The laser module emits a laser beam onto the heating ring 34 to heat the heating ring 34.

[0045] This design allows the laser module to irradiate and heat the two rotating heated rings 34 from the side.

[0046] In one embodiment, a mounting bracket 7 is mounted on the bottom of the mounting platform 32, and the heating module 5 is vertically mounted on the mounting bracket 7, with the emitting end of the heating module 5 facing the opening 4.

[0047] In practice, the heating module 5 is installed at the bottom of the UAV 1 through the above-mentioned components. It takes off synchronously with the UAV 1. The purpose is to ensure that the launching end of the heating module 5 can be accurately aligned with the opening 4, so that it is not affected by the cable drift and can accurately heat the heating ring 34.

[0048] In another embodiment, unlike the above embodiments, a ground engineering vehicle is also included. A position recognition module is installed on the ground engineering vehicle. The heating module 5 is movably installed on the ground engineering vehicle. The position recognition module is used to identify the C-shaped frame 33 with the opening 4, so that the emitting end of the heating module 5 faces the opening 4. The position recognition module can be an image recognition module. Its specific recognition method is a well-known technology in the field. Therefore, its specific structure and working principle will not be described in detail in this article.

[0049] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0050] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0051] Additionally, "multiple" refers to two or more.

[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
