Description

Technical Field

[0001] The invention relates to the technical field of power transmission line deicing, and in particular to an impact vibration device for deicing overhead power transmission lines. Background Art

[0002] Transmission line icing is a common natural phenomenon, especially in cold and wet climates. Supercooled water droplets condense into ice when they hit the surface of transmission lines and transmission towers below freezing. Severe line icing is the most threatening natural disaster to the normal operation of the power grid. After severe ice and snow weather, severe line icing may cause transmission line overload, which may lead to line breakage, hardware damage, continuous tower collapse, and even severe accidents such as continuous discharge, burning and explosion of substation equipment.

[0003] There are many deicing robots available. However, among the wide variety of deicing robots, the working mode of their working heads mostly continues the traditional ice scraping method, which is not conducive to efficient and stable operations in large-span flexible conductor environments. For large-span flexible conductors, the existing deicing method is usually to manually operate an insulating rod to knock on the conductor for deicing; or, when the conductor is high, to knock through it through drone operation; but the knocking force is difficult to guarantee the deicing effect; at the same time, ice formation occurs continuously, and deicing needs to be carried out at intervals, and it is difficult to remove ice in time by manual or drone knocking; therefore, the above-mentioned manual knocking and drone knocking methods are not suitable in terms of efficiency and convenience.

[0022] An embodiment of the present application discloses an impact vibration device for de-icing overhead power transmission lines, the device includes a base plate, two mounting components are provided on the base plate, the base plate can be mounted on the conductor through the mounting components, wherein the mounting component includes a mounting seat 11 and a buckle 12, the mounting seat 11 is fixedly connected to the base plate, and the buckle 12 is detachably connected to the mounting seat 11 by bolts; after the buckle 12 is connected to the mounting seat 11, a mounting hole for the conductor to pass through is formed between the two; during installation, the conductor is placed in the two mounting holes, and then the buckle 12 is fixed to the mounting seat 11. It should be noted that the mounting component and subsequent guide rods 22 and other structures are located on both sides of the base 1.

[0023] A base 21 is also provided on the base plate, and a guide rod 22 is inserted into the base 21. A connecting plate is provided at the other end of the guide rod 22 away from the base 21. A spring 23 is provided on the outer sleeve of the guide rod 22, and the two ends of the spring 23 are respectively connected to the base 21 and the connecting plate. The spring 23 can be compressed first and then released instantly to generate strong impact vibration on the base plate. A pulse component for compressing the spring 23 is also provided on the base plate.

[0024] In the present application, the pulse assembly includes an incomplete gear 32 and a rack 31, the incomplete gear 32 is rotatably connected to the base 1, and the rack 31 is connected to the guide rod 22, the length directions of the two are consistent, and the rack 31 is meshed with the incomplete gear 32; the pulse assembly also includes a driving assembly for driving the incomplete gear 32 to rotate; the driving assembly includes a motor 43, a rotating rod 33 and a transmission assembly; the rotating rod 33 is rotatably connected to the base 1 through a bearing and is coaxially connected to the incomplete gear 32; the transmission assembly is used to transmit the torque of the motor 43 to the rotating rod 33, and each group of transmission assemblies includes two worms 42 and two turbines 41, the two worms 42 are coaxially fixedly connected, the worms 42 are rotatably connected to the base 1, and the rotation axis of the worms 42 is arranged along the length direction of the rack 31; one of the turbines 41 is arranged on the output shaft of the motor 43 and meshes with the worm 42, and the other turbine 41 is arranged on the rotating rod 33 and meshes with the worm 42.

[0025] At the same time, in order to facilitate the driving motor 43, a CT power module is also provided on the base 1. It is a mature technology. The CT power module is a power supply device based on the principle of electromagnetic induction. It obtains electric energy from the power line through a current transformer (CT) and converts it into a stable DC voltage. This module is widely used in the fields of high-voltage power transmission and distribution, smart grids, etc., providing continuous power supply for various smart electronic devices.

[0026] In order to keep the rotating rod 33 under balanced force, two transmission assemblies are provided. The motor 43 is a double-headed output motor 43 .

[0031] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
