Abstract

The invention relates to a bird repellent, which comprises a casing sleeved on an electric wire, two pairs of counterweights respectively arranged at both ends of the lower end of the casing, a bracket installed on the casing, a frame structure and a top frame arranged on the top of the bracket, The brush arm arranged on the top shelf, the knocking hammer arranged on the bracket, the rotating cylinder arranged on the bracket and located on one side of the hammer, the sounding sheet arranged on the rotating cylinder and in intermittent contact with the hammer, And the wind whistle set on the bracket. When the present invention is used, the disadvantage of the horizontal frame of the bird repellent being placed on two electric wires is avoided, and the reason of the horizontal frame setting of the bird repellent is prevented from being connected to electricity in wet weather and causing malfunctions.

Description

bird repellent

technical field

The present invention relates to a bird repellent.

Background technique

With the continuous strengthening of human awareness of the protection of the natural ecological environment, the number of birds is increasing year by year, and the scope of activities is expanding day by day, which has caused great harm to power distribution lines, and the work of preventing bird damage on lines is imminent.

1. The harm of birds to distribution lines

Birds build nests. In spring, birds start to build nests on power distribution line towers to lay eggs and hatch. Birds carry branches, iron wires, firewood and other debris in their mouths and fly back and forth over the road. When iron wires and other objects fall between the cross arm and the conductor, it will cause line failure. When the wind blows, the bird's nest on the tower is blown away by the wind and falls on the live wire or insulator, causing a short-circuit ground fault.

Guano flashover. The feces excreted by birds pollute the insulators, and in bad weather such as humid air, heavy fog, and haze, flashovers are prone to occur and cause failures.

2. Characteristics of bird damage faults

The topography and landforms that cause bird damage are hidden near rivers, reservoirs, low-lying and humid areas; there are large trees and some villages, secluded and open farmland.

3. Existing bird repelling technology

Existing bird-repelling measures include wind-driven bird-repelling devices and ultrasonic bird-repelling devices.

Pneumatic bird repellents have design defects such as high failure rate and loss of bird repelling efficiency in calm weather, which cannot effectively prevent birds from nesting in dangerous parts of equipment structures and towers, which may easily lead to bird damage failures.

When the ultrasonic bird repellent senses that birds are approaching, it will emit a warning sound to drive the birds to roost and nest in dangerous areas on the tower. The device has a remarkable effect on preventing birds from building nests at dangerous parts of the tower. However, after a period of application, the birds got used to the eagle model and screams of the bird repellent, and then began to build nests in dangerous parts on the tower again, which could not effectively control the occurrence of bird damage failures.

Contents of the invention

The technical problem to be solved by the present invention is generally to provide a bird repellent; the technical problem solved in detail and the beneficial effect achieved are described in detail in the following content and in conjunction with specific embodiments.

In order to solve the problems referred to above, the technical scheme that the present invention takes is:

A bird repellent, comprising a casing sleeved on the electric wire, two pairs of counterweights respectively arranged at both ends of the lower end of the casing, a bracket installed on the casing, a frame structure and a top frame set on the top of the bracket, and a top frame set on the top of the bracket. The brush arm of the frame, the knocking hammer arranged on the support, the rotating cylinder arranged on the support and positioned at one side of the striking hammer, the sounding sheet arranged on the rotating cylinder and in contact with the striking hammer intermittently, and the Whistle on stand.

When using the present invention, avoid the disadvantages of the horizontal frame of the bird repellent on the two wires, avoid the connection of electricity in wet weather due to the installation of the horizontal frame of the bird repellent, and cause failures. Structure, through the clamps, bolts and other fasteners to make it frictionally contact with the wire, avoid axial movement, easy to disassemble, through the counterweight to make the bird repellent stand up better, similar to the principle of a tumbler, through the brush arm To frighten and drive away birds by swinging in the breeze, it is better to attach flexible and light insulating tapes such as ribbons for better effect. The wind whistle, percussion hammer and sounding piece will produce noise, frightened sounds or imitate the sounds of natural enemies through the wind to drive the rotating cylinder, and further Keep birds away.

The beneficial effects of the present invention are not limited to this description, and for better understanding, a more detailed description is given in the specific embodiment section.

Fig. 1 is the structural representation of the present invention.

Among them: 1. Wire; 2. Sleeve; 3. Counterweight; 4. Bracket; 5. Top frame; 6. Brush arm; 7. Knocking hammer; post.

Detailed ways

As shown in Figure 1, the bird repellent of the present embodiment includes a casing 2 sleeved on the electric wire 1, two pairs of counterweights 3 respectively arranged at both ends of the lower end of the casing 2, a bracket 4 installed on the casing 2, Frame structure and the top frame 5 that is arranged on the top of the support 4, the brush arm 6 that is arranged on the top frame 5, the percussion hammer 7 that is arranged on the support 4, the rotation that is arranged on the support 4 and is located at one side of the percussion hammer 7 The drum 8 , the sounding piece 9 arranged on the rotating drum 8 and in intermittent contact with the hammer 7 , and the wind whistle 10 arranged on the bracket 4 .

When using the present invention, avoid the disadvantages of the horizontal frame of the bird repellent on the two wires, avoid the connection of electricity in wet weather due to the installation of the horizontal frame of the bird repellent, and cause failures. 2 structure, through the fasteners such as clamps and bolts to make it frictionally contact with the wire, avoid axial movement, easy to disassemble, and use the counterweight 3 to make the bird repellent stand up better, similar to the tumbler principle, through the hair The brush arm 6 swings in the breeze to frighten and drive away the birds. It is preferable to attach flexible and light insulating tapes such as ribbons for better effect. The wind whistle 10, the percussion hammer 7 and the sounding piece 9 produce noise and panic by driving the rotating cylinder 8. Sound or imitate the sound of natural enemies to further drive birds away.

The invention is reasonable in design, low in cost, strong and durable, safe and reliable, simple in operation, saves time and effort, saves money, has compact structure and is convenient to use.
