High-altitude regeneration obstacle clearing device for power grid

Abstract

The invention discloses a high-altitude regeneration obstacle clearing device for a power grid, and the device comprises an operation substrate, a clearing mechanism disposed on a control substrate, and a control mechanism disposed at the tail end of the clearing mechanism. The operation substrate comprises a supporting column, a support disposed at the lower part of the supporting column, and a ratchet wheel module which is disposed at the upper part of the supporting column and is connected with the clearing mechanism. An isolation mechanism is disposed between the clearing mechanisms. A ratchet wheel is used for controlling the lifting of a supporting arm, and a working arm is enabled to carry out downward pressing successfully under the action of an electric telescoping rod. After the action of an elastic avoiding ring, a to-be-trimmed branch is sawed off. Moreover, because the device is provided with the isolation mechanism, the device can prevent wood flours from falling onto the whole body of an operator when the operator carries out operation. The device is simple in structure, is simple and convenient for operation, and is worthy of application and popularization.

Description

technical field [0001] The invention belongs to the technical field of obstacle removal tools for transmission lines, and in particular relates to a device for cleaning obstacles to regeneration at high altitudes of power grids. Background technique [0002] In recent years, with the development of cities and the continuous construction of roads and industrial parks, transmission lines have gradually been "relocated" from farmland to cities and suburbs, resulting in the increasing number and height of green trees, landscape trees, and street trees in transmission line protection areas. With the development of the economy, farmers' economic awareness is constantly improving, and there are more and more nurseries for economical fruit trees and precious tree species, resulting in growing contradictions between tree lines. There are also some grave trees under the wires, which have grown from small to large, and the longer they grow, the taller they are. Due to the traditional s...

Problems solved by technology

The operating arm can drive the operating arm to complete a 30° left and right swing at the swing joint, so that the robot's working area can completely cover the cone-shaped space with a solid angle of 60° below the robot; but its structure is complex and costly

[0005] Disclosed in 201320459988.9 is an auxiliary drag hook for tree and bamboo obstacle removal on power transmission lines, including a hook head and an insulating hook handle, the hook head is provided with a plug-in hole, and the front end of the hook handle is provided with a plug-in rod that can be inserted into the plug-in hole , the hook head is connected with an insulating pull rope. When in use, the personnel insert the plug rod into the plug hole from a safe distance, send the pull hook to the place where the branches and leaves of the tree need to be felled through the hook handle, and pull the branches and leaves close by the pull rope to complete the cutting process. Felling can not only eliminate the potential safety hazard of electric shock, but also prevent the cut off branches and leaves from hitting the line or equipment to cause damage. In addition, there are multiple hooks, which are easier to hook the branches, and the insertion rod is bent, which is easy to deal with The hooked branches can be directly used as pull hooks, and the length of the hook handle can be adjusted according to the actual situation, which is convenient to use; but it still fails to solve the phenomenon of being injured by falling branches
