Description

Technical Field

[0001] The invention relates to the technical field of power transmission line maintenance, and in particular to a high-altitude power transmission tower ice and snow removal device based on an unmanned aerial vehicle. Background Art

[0002] At present, my country's demand for electric energy is increasing, and the effective operation of power transmission and distribution is related to people's daily life and work. However, due to force majeure in nature, there are certain safety hazards in the lines, which also bring troubles to normal power transmission and distribution. It is a natural disaster for transmission lines. When encountering heavy snow weather, a lot of snow will accumulate on the insulators of the transmission towers. If it is not cleaned for a long time, it will affect the normal operation of the insulators and even cause safety hazards.

[0003] When the surface of the high-voltage insulator is covered with snow or bridged by ice, the insulation strength decreases and the leakage distance shortens. During the snow melting process, the water film on the surface of the snow or ice crystals will quickly dissolve the electrolyte in the dirt, increase the conductivity of the melted ice water or the water film on the ice surface, and cause the distortion of the voltage distribution of the high-voltage insulator string. As the voltage rises sharply, the high-voltage insulators at both ends will also cause the distortion of the surface voltage distribution of the single high-voltage insulator, thereby reducing the flashover voltage of the ice-covered high-voltage insulator string. At the same time, the snow melting period is usually accompanied by heavy fog. The dirt particles in the atmosphere are contained in the fog as condensation nuclei, which will further increase the conductivity of the ice water when the snow on the high-voltage insulator melts. The relevant test data show that the heavier the snow, the greater the voltage distribution distortion, and the higher the percentage of voltage withstand at both ends of the high-voltage insulator string, especially the high-voltage end of the high-voltage insulator. As the conductivity of ice water increases, the leakage current also increases under the action of the power frequency voltage. When it increases to a certain level, a flashover channel is formed and the line trips.

[0004] With the continuous application of drone technology, drones can be controlled very flexibly and can accomplish some difficult tasks instead of manual labor. In the existing technology, some power transmission snow and ice removal devices have been equipped with blades and sprayed with snow-melting agents to remove ice and snow from power transmission lines. The snow-removing effect of the snow-spraying agents and blades on the snow and ice removal devices is somewhat difficult, and the blades are prone to damage the lines.

[0005] Therefore, there is an urgent need for a high-altitude transmission tower deicing device based on drones to replace manual work to reliably, safely and efficiently complete the deicing work of high-voltage insulators on transmission towers. Summary of the invention

DETAILED DESCRIPTION

[0032] The present invention will now be described in further detail.

[0033] The present invention provides a technical solution for a high-altitude transmission tower deicing device based on a drone:

[0034] Embodiment 1:

[0036] The ice and snow removal assembly includes an operating rod 4, a first cross beam 6, a second cross beam 7, and a wiping module; the left end of the operating rod is fixedly provided with a wiping module 5, and the right end of the operating rod passes through and connects the first cross beam 6 and the second cross beam 7, the first cross beam 6 and the second cross beam 7 are hinged on the landing gear 2, and the landing gear 2 is two, and the two landing gears 2 are arranged on the left and right sides of the lower surface of the UAV body 1, and the wiping module 5 is a rectangular structure.

[0037] The two ends of the first crossbeam 6 and the second crossbeam 7 are fixed to the two landing gears 2 on the lower surface of the UAV body by hinged connection. The hinged parts are detachable aluminum alloy fasteners 8, and there are four of them. The detachable aluminum alloy fasteners 8 are rectangular, with first through holes 81 on the left and right sides, and second through holes 82 on the front and back sides. The landing gear 2 passes through the first through holes 81 of the detachable aluminum alloy fasteners 8; the first crossbeam 6 and the second crossbeam 7 pass through the second through holes 82, and the first crossbeam 6 is on the left side of the second crossbeam 7.

[0038] The right end of the operating rod 4 penetrates the first cross beam 6 and the second cross beam 7. The operating rod 4 and the first cross beam 6 and the second cross beam 7 are fixed at the intersection with a wrapping belt 9 to prevent the operating rod 4 from shaking when in use. The operating rod 4, the first cross beam 6, and the second cross beam 7 are made of epoxy resin, which is light in weight and reduces the weight of the ice and snow removal assembly.

[0039] The wiping module 5 includes a brush plate 51, bristles 52 and a brush rod 53. The brush plate 51 is a rounded rectangular structure. The bristles 52 are slender strips. The bristles 52 are bonded to the gasket at the bottom of the brush plate. The brush rod 53 is provided with external threads. The bristles 52 are at the end away from the external threads of the brush rod 53. The wiping module 5 is connected to the operating rod through threads.

[0040] In this embodiment, the drone body 1 is a prior art, which can provide sufficient lift and drive the snow and ice removal assembly to rise and operate stably. In the specific snow and ice removal process of the present invention, the end of the operating rod 4 away from the drone is first connected to the brush rod 53 through a thread, and then the snow and ice removal device is connected to the drone body 1 through a detachable aluminum alloy fastener 8.

The state of snow accumulation on the transmission tower insulator can be viewed through the camera 3, which is beneficial for the operation and maintenance personnel to control the flight altitude of the drone body, and also realizes multi-angle precise acquisition of the camera 3. This embodiment realizes the adjustment of the camera 3 to approach and move away from the insulator target through the drone body 1. The adjustment angle is comprehensive and reliable, which is beneficial for the precise positioning of the wiping module 5 and precise ice and snow removal.

[0044] During operation, the drone transmission module transmits wireless signals with a maximum transmission distance of 120m. The camera 3 can transmit the captured image information to the drone body 1 processing unit for processing. The processing unit sends the processed image information to the drone body 1 control unit. The drone body 1 control unit transmits the image information through the antenna. The monitoring system on the ground receives the image information sent by the drone body through the receiving antenna and the receiver, and then transmits it to the ground control human-computer interaction for display. The operation and maintenance personnel can observe the current image captured by the drone, and store the camera's shooting status through the storage unit for future browsing and query.
