Abstract
Description
Technical Field
[0001] This utility model relates to the field of bird deterrence devices, specifically to a bird deterrence device that can both effectively deter birds and avoid harming them. Background Technology
[0002] Birds frequently nest on the crossarms of power transmission line poles. When these nests become wet or damp from rain, they can easily cause line faults. Bird droppings can also cause short circuits. Extensive bird nesting and other activities can lead to frequent and widespread power outages. Therefore, implementing effective bird deterrence measures to prevent bird activity from causing power line faults and ensuring the safe and stable operation of the power grid is a crucial task for the power sector.
[0003] Common bird deterrence methods mainly involve bird deterrents, such as sound bird deterrents, strong light flashing bird deterrents, wind-powered bird deterrents, and ultrasonic bird deterrents. After these bird deterrents are installed in one location for a long time, birds become accustomed to them, and intelligent birds such as magpies may even develop immunity, making the bird deterrents generally ineffective. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a bird deterrent device that can effectively deter birds without causing harm to them, thus achieving both safety protection and eco-friendliness.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows.
[0006] A bird deterrent device includes a base plate installed on a utility pole crossarm, a connecting plate mounted on the base plate, and a layer of long spikes and a layer of short spikes arranged at intervals along the length of the connecting plate. The short spike layers are located between two adjacent layers of long spikes. The long spike layers consist of a number of long spikes arranged at even intervals perpendicular to the length of the connecting plate, and the short spike layers consist of a number of short spikes arranged at even intervals perpendicular to the length of the connecting plate.
[0007] In the aforementioned bird deterrent device, the long spike and the short spike are both conical structures designed in the style of jujube thorns, and the height of the long spike is greater than the height of the short spike, and the bottom circumference diameter of the long spike is greater than the bottom circumference diameter of the short spike.
[0008] The bird deterrent device described above has threaded holes on the connecting plate, and the connecting plate is connected to the base plate by connecting bolts.
[0009] In the aforementioned bird deterrent device, a magnetic plate is provided at the bottom of the base plate, which is magnetically attached to the crossarm of the utility pole. The magnetic plate is bonded to the base plate with structural adhesive.
[0010] In the aforementioned bird-repelling device, the magnetic plate is a single magnetic plate laid under the base plate.
[0011] In the aforementioned bird-repelling device, the magnetic plate consists of several magnetic strips laid at intervals below the base plate.
[0012] The base plate of the aforementioned bird deterrent device is made of PVC material.
[0013] The technological advancements achieved by this utility model are as follows, due to the adoption of the above technical solutions.
[0014] This utility model provides a bird deterrent device. Because the top of the device is a conical spike structure with a biomimetic jujube thorn, when birds land on the bird deterrent device on the crossarm of the utility pole, the birds feel the pain caused by the spikes and fly away from the area. Moreover, the conical tip of the spike is a smooth structure and will not cause great harm to the birds. It achieves efficient bird deterrence without harming the birds and avoids the birds developing an immune response and continuing to build nests on the crossarm of the utility pole.
[0015] This utility model uses a base plate with a magnetic plate at the bottom to magnetically connect with the crossarm of the utility pole, making installation and disassembly convenient and greatly reducing the cost of later maintenance and repair. It is time-saving, labor-saving and more economical. In addition, the base plate is made of high-quality PVC material, which has excellent anti-corrosion and anti-aging properties. It can withstand extreme climates such as severe cold, high temperature and humidity, and is durable and can ensure a long-term stable protective effect. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0021] Bird deterrent devices, such as Figures 1 to 3 As shown, it includes a base plate 1 installed on the crossarm of a utility pole, a connecting plate 3 installed on the base plate 1, and a layer of long spikes and a layer of short spikes arranged at intervals along the length of the connecting plate 3. The short spike layers are located between two adjacent layers of long spikes. The long spike layers are composed of a number of long spikes 4 arranged at even intervals perpendicular to the length of the connecting plate 3, and the short spike layers are composed of a number of short spikes 5 arranged at even intervals perpendicular to the length of the connecting plate 3.
[0022] The long spike 4 and the short spike 5 are conical structures designed to mimic the shape of jujube thorns. The height of the long spike 4 is greater than that of the short spike 5, and the bottom circumference diameter of the long spike 4 is greater than that of the short spike 5.
[0023] The tops of the long spike 4 and the short spike 5 are rounded to prevent the conical tips from being too sharp and causing damage to birds.
[0024] Furthermore, the long spikes 4 and short spikes 5 can be conical hollow structures, which can reduce the amount of material used in the spike production process.
[0025] The connecting plate 3 has threaded holes 6 around its perimeter. The connecting plate 3 is connected to the base plate 1 by connecting bolts 7, so that the connecting plate 7 and the base plate 1 are stably connected, ensuring the stability of the device installed on the utility pole.
[0026] Furthermore, the connecting plate 3 and the base plate 1 are bonded together with structural adhesive to prevent the connecting bolts 7 from loosening and affecting the stability between the connecting plate 3 and the base plate 1.
[0027] A magnetic plate 2 is provided at the bottom of the base plate 1. The magnetic plate 2 is bonded to the base plate 1 with structural adhesive. The magnetic plate 2 can attract the entire device to the crossarm of the utility pole, making installation and disassembly simple.
[0028] The magnet plate 2 can be made of a strong magnet to prevent the device from falling due to environmental factors and to enhance the stability of the device connection.
[0029] The magnet plate 2 can be a whole magnet plate laid under the base plate 1, or it can be a number of magnet strips laid at intervals under the base plate 1.
[0030] The base plate 1 is made of high-quality PVC board, which has excellent anti-corrosion and anti-aging properties. It can withstand extreme climates such as severe cold, high temperature and humidity, and is durable, ensuring long-term stable protection.
[0031] When birds land on the bird deterrent device on the utility pole crossarm, the device's cone-shaped spikes, designed to mimic the shape of a jujube thorn, will prick the birds. However, this will only cause the birds pain and will not harm them. After feeling the pain, the birds will fly away from the area. This method effectively deters birds while ensuring zero harm to animals, achieving both safety and eco-friendliness.
