Detailed Description
Embodiments of the present invention will be described in further detail below. What is not described in detail in the embodiments of the present invention belongs to the prior art known to those skilled in the art.
The invention relates to an anti-bird shoulder rest device for an additional wire of a contact net, which comprises the following preferred specific embodiments:
the device comprises a vertical cone-shaped shoulder frame body, wherein one end of the vertical cone-shaped corner shoulder frame body is fixed with a groove-type fixing base, and the other end of the vertical cone-shaped corner shoulder frame body is hung with an insulator or an additional wire fixing clamp through an inverted T-shaped bolt;
the groove-type fixing base is fixed with the contact net support column through the U-shaped anchor ear and the anti-loosening fastening device; or the groove type fixed base is arranged on a column reserved hole of the contact net column.
The vertical cone type shoulder frame body is of a triangular hollow tube structure, a triangular sharp edge at the top is provided with a pin header, a triangular bottom surface at the bottom is provided with a cutting groove, two wings after the cutting groove are provided with an internal tooth structure and are thickened and inwards warped, and the inverted T-shaped bolt is arranged in the cutting groove and is clamped by the warped internal tooth.
One side of the triangular sharp edge at the top of the vertical cone-shaped shoulder frame body is a vertical surface, and the other side is a single conical surface with the inclination larger than 60 degrees.
The groove-type fixed base is of a groove-type inverted buckle structure and is integrally formed with the vertical cone-shaped shoulder frame body through welding connection or by adopting an integral metal film casting process.
The vertical cone type shoulder rest body is made of carbon structural steel, high-quality carbon structural steel or composite materials.
The outer surface of the vertical cone type shoulder rest body material is coated with aromatic nontoxic medicines.
For bird damage prevention work, birds are prevented from occupying from the source, the effective section of the designed shoulder frame enables the birds to be unable to stand on the shoulder frame from the bionic angle of the birds, and the bird nest material is unable to root, so that the possibility of nesting is fundamentally prevented. And smell is expelled, and the outer surface of the material of the shoulder rest is coated with aromatic nontoxic medicine.
