Description

Conical three-dimensional anti-bird device

technical field

The invention relates to a cone anti-bird device on a straight pole tower in a power transmission line of a power system. The bird prevention device can be widely used on a straight pole tower of an overhead power transmission line with a voltage level of 66 kV or above.

Background technique

In recent years, due to the intensification of afforestation efforts and the strengthening of legal protection, vegetation has been restored and developed, ecological conditions have been improved, and bird species and numbers have increased. In the densely populated eastern and northern mountainous areas of Dandong (mountainous), bird activities Frequently, this increases the probability of transmission line faults caused by birds nesting on the line and other activities. At present, the anti-bird devices widely used on the straight poles and towers of transmission lines are mostly "bird-repelling thorn" devices. The device is installed above the hanging point of the linear insulator string, which plays a role in preventing birds to a certain extent, but it is also found that birds can still build nests on the device. It is still possible to nest branches etc. on top, and the "bird repelling spines" do not have a covering effect, so they cannot prevent bird droppings from dripping on the insulator strings. In the power system, bird droppings have a great impact on the safe operation of transmission lines. Every year, bird droppings on the insulator strings cause a very high failure rate such as line tripping. In particular, a line flashover grounding fault caused by activities such as nesting, staying, and defecation above the hanging point of the linear insulator string, a cone-shaped bird prevention device suitable for transmission lines in mountainous areas has been developed.

The development advantages of this transmission line cone anti-bird device: it can prevent birds from nesting on the pole tower, especially on the insulator of the straight pole tower. The anti-guano cone device is one of the protective devices that can not only protect the safety of the transmission line, but also protect the birds.

Contents of the invention

The present invention aims at the problems existing in the above-mentioned prior art, and provides a cone-shaped anti-bird device capable of preventing birds from building nests on a cross-arm above a linear insulator and bird feces dripping on the insulator to cause flashover, which solves the problem In the prior art, it is necessary to manually climb the tower regularly to remove the bird's nest and other problems.

Technical scheme of the present invention is as follows:

The cone-shaped three-dimensional bird-proof device includes a cone-shaped bird-proof device cover, a metal pole, and a U-shaped base for the bird-proof device. The outer cover of the bird device is a cone structure with a cutting angle not exceeding 60°, and the outer surface is coated with patterns that are sensitive and irritating to birds.

The metal pole is connected to the U-shaped base of the bird-proof device through the pole-fixing screw, and the U-shaped base of the bird-proof device is fixed on the cross arm on the linear insulator through the base fixing screw.

The pattern sensitive and irritating to birds is a red snake pattern.

The outer cover of the cone-shaped bird-proof device is a closed hollow body structure.

The beneficial effects of the present invention are as follows:

The invention is applied to the linear insulators of 66 kV line towers, with small investment and low cost, and effectively covers the lower insulators. At the same time, its conical design can prevent birds from resting, staying, and building on the upper cross-arm of the insulators. Nests, etc., can also prevent bird droppings from dripping on the insulator strings. The surface is coated with irritating patterns that scare birds, which can effectively prevent birds from approaching, so as to achieve the purpose of three-dimensional anti-bird damage, and reduce the need for line operators to climb towers and remove them. The number of bird nests reduces the labor intensity and danger of operators.

Detailed ways

    Referring to the accompanying drawings, the present invention will be described in detail in combination with specific embodiments.

Example

As shown in Figures 2 and 3, the cone-shaped three-dimensional bird-proof device, the cone-shaped bird-proof device cover at the upper end of the device can be divided into two shapes, which are inverted cone-shaped umbrellas (applied to linear poles and towers with a single string of linear insulators) top); ridge type (applied above the double-string linear insulators of straight pole towers), the material can be steel, PVC composite material or alloy material, the outer surface is painted with red serpentine fluorescent pattern, and it is installed on the straight line through the metal pole and the base Above the connection between the string hanging point of the tower insulator and the cross-arm of the tower, its umbrella-shaped shape effectively covers the insulator below. At the same time, its conical and ridge-shaped design can prevent birds from resting, staying, and Nesting, etc., can also prevent bird droppings from dripping onto insulator strings, so as to achieve the purpose of three-dimensional anti-bird damage.

Concrete use process of the present invention is as follows:

Install the three-dimensional bird-proof device on the cross arm above the linear insulator string according to the position marked in attached drawing 1, and the three-dimensional bird-proof device outer cover 1 made of steel, PVC composite material or alloy material (inverted conical type for single string and inverted conical for double string) Roof type), the metal pole 2 is plugged with the U-shaped base 3 of the anti-bird device, the U-shaped base 3 is inserted into the cross arm, and the lower part is tightened with the fixing screw 4 to hold it firmly. In this way, the three-dimensional anti-bird device will cover the insulator string below, so that birds can be prevented from resting, staying, and nesting at the cross-arm on the upper part of the insulator, and at the same time, bird droppings can be prevented from dripping onto the insulator string.
