Column switch nest removing apparatus based on insulating rod

Abstract

The invention discloses a column switch nest removing apparatus based on an insulating rod. The lower part of a base (2) is provided with an insulating rod screw joint slot (7), the upper part of the base (2) is provided with a gear buckle built-in groove (9), a gear mechanism (3) is integrally formed by a gear seat (3-1) and a gear buckle (3-2) protruding out of the gear seat (3-1), a gear buckle (3) is embedded in the gear buckle built-in groove (9), the gear seat (3-1) is connected with a work arm (1), the base (2), the gear mechanism (3), and the work arm (1) are fastened together through a wing-shaped nut (4), a pad (5), and a wing-shaped screw (6), the work arm (1) is in an inverted-V shape, the top angle alpha is arranged at an angle of 150 degrees, the front end of the work arm (1) is connected with a removing hook (8), and the removing hook (8) is integrally formed by a connecting rod (8-1) vertical to the work arm (1) and two obtuse-angle small hooks (8-2) at the two ends of the connecting rod (8-1). The column switch nest removing apparatus is simple in structure, convenient and flexible in use, high in safety coefficient, and low in cost, and can effectively reduce the operation and maintenance costs of overhead lines.

Description

Technical field: [0001] The invention relates to a pole-mounted switch bird's nest removal device based on insulating rods, which is widely used in the removal of various pole-mounted switch bird's nests in power systems, and belongs to the technical field of power grid distribution line operation and maintenance. Background technique: [0002] Bird's nest is a common frequent hazard of overhead distribution lines. The grid line located in the habitat of birds' migration, bird's nest is very harmful to overhead lines. In bad weather, it is very easy to cause faults such as short circuit between phases and single phase grounding of overhead lines, resulting in tripping of the whole line. [0003] The existing device for clearing the bird's nest mainly uses the protruding part of the head of the insulating operating rod. The staff stands on the ground or climbs on the rod, and at the same time keeps a sufficient safe distance from the live part, and directly hooks and pushes t...

AI Technical Summary

Problems solved by technology

[0008] Compared with the prior art, the present invention can produce the following positive effects: the present invention can effectively solve the problem that ordinary insulating rods cannot remove the bird's nest above the switch on the pole, and can avoid the potential safety hazard of electric shock that is likely to occur when live work is used to remove such bird's nest. Avoid the cumbersome procedures and high cost of live work to remove such nests
