Description

Technical Field

[0001] This utility model relates to the field of power transmission line technology, specifically to a self-powered ultrasonic bird repeller. Background Technology

[0002] With the improvement of the ecological environment, the number of birds has increased. However, birds often nest and defecate frequently on the tops of overhead power transmission towers. Bird droppings can contaminate insulators, reduce their insulation performance, and cause flashover accidents. Nesting materials can also cause short circuits, posing a serious threat to the safe operation of the power system and grid. Therefore, various devices that use chemical agents or have environmental impacts have emerged to drive birds away from transmission lines. With the development of ultrasonic technology and the growing popularity of environmental protection and sustainable development concepts, self-powered ultrasonic bird repellers have appeared. Self-powered ultrasonic bird repellers use physical methods to drive birds away, do not rely on chemical agents, are non-toxic and odorless, and do not produce any environmental pollution. They can effectively drive away birds, solve bird damage problems, and protect the survival rights of birds to the greatest extent, achieving harmonious coexistence between humans and nature.

[0003] After a period of use, birds adapt to the fixed characteristics of the ultrasonic waves emitted by the generator, and the bird-repelling effect of the existing self-powered ultrasonic bird repeller will drop sharply, resulting in the problem of low persistence of the bird-repelling effect of ultrasonic bird repeller. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the sound characteristics of existing self-powered ultrasonic bird repellers are easily adapted to by birds, resulting in a short-lasting bird repeller effect. This invention provides a self-powered ultrasonic bird repeller.

[0005] To address the shortcomings of the aforementioned technical problems, the present invention adopts the following technical solution: a self-powered ultrasonic bird repeller, comprising a self-powered component installed on a power transmission line, a bird repeller component provided on one side of the self-powered component in the axial direction, and the bird repeller component being powered by the self-powered component.

[0006] The bird deterrent assembly includes a support shell fixedly disposed on one axial side of the self-powered assembly, a sound generator fixedly disposed on the support shell, and a bearing shell rotatably disposed on the outer periphery of the support shell.

[0007] The outer periphery of the support shell is uniformly provided with multiple wind turbine blades, and the support shell is uniformly provided with multiple barrier plates. The multiple barrier plates can cover the sound-emitting part of the sound generator in sequence as the support shell rotates, and the multiple barrier plates have different elastic moduli or densities.

[0008] As a further optimization of the self-powered ultrasonic bird repeller of this utility model: the plurality of the blocking plates are respectively made of iron-based, nickel-based or cobalt-based alloy materials.

[0009] As a further optimization of the self-powered ultrasonic bird repeller of this utility model: the bearing shell is provided with a plurality of through holes evenly distributed, and the blocking plate is disposed in the through holes.

[0010] As a further optimization of the self-powered ultrasonic bird repeller of this utility model: a positioning element for positioning is provided on the side of the self-powered component away from the bird repeller component.

[0011] As a further optimization of the self-powered ultrasonic bird repeller of this utility model: the positioning component includes two connecting tiles, any one of which is fixed on the self-powered component, and the two connecting tiles are connected to the power transmission line by locking pins.

[0012] As a further optimization of the self-powered ultrasonic bird repeller of this utility model: a clamping ring is provided on the opposite surfaces of the two connecting tiles, and the clamping ring is made of insulating rubber.

[0013] As a further optimization of the self-powered ultrasonic bird repeller of this utility model, the feature is that: a rotating rail is fixedly provided on the outer periphery of the support shell, and the rotating rail is rotatably connected to a rotating ring fixed on the bearing shell.

[0014] As a further optimization of the self-powered ultrasonic bird repeller of this utility model, the feature is that the bearing shell, the rotating rail and the rotating ring are all C-shaped, and the notch of the rotating ring is smaller than the notch of the rotating rail.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This invention utilizes multiple wind-powered fan blades on the outer circumference of the supporting shell to drive its rotation. Due to the irregularity of the wind, the rotation direction and speed of the supporting shell are also irregular. Subsequently, multiple barrier plates made of different materials on the supporting shell pass irregularly through the ultrasonic wave emitted by the sound generator. This causes the wavelength of the ultrasonic waves emitted by the sound generator to change irregularly, thus constantly changing the characteristics of the ultrasonic waves. This makes it difficult for birds to adapt, thereby maintaining a continuous deterrent effect on birds and making the bird-repelling effect more lasting. Attached Figure Description

[0020] To better understand this utility model, the following embodiments further illustrate the content of this utility model, but the content of this utility model is not limited to the following embodiments.

[0021] like Figure 1 and Figure 2 As shown, a self-powered ultrasonic bird repeller includes a self-powered component 2 installed on a power transmission line. Specifically, the self-powered component 2 is a CT power harvesting device BNWGK-300 manufactured by Hubei Tianrui Electronics Co., Ltd. Positioning components 1 and bird repeller components 3 are fixedly connected to the axial sides of the housing of the self-powered component 2, respectively. The self-powered component 2 and bird repeller components 3 are electrically connected to provide energy for the operation of the bird repeller components 3 in an energy-saving and environmentally friendly manner, ensuring stable operation. Specifically, the self-powered component 2 includes a current transformer, which induces electrical energy from the power transmission line to provide power. The positioning component 1 connects to the power transmission line to assist the bird repeller components 3 and the self-powered component 2 in positioning them appropriately on the power transmission line. The bird repeller components 3 include a support shell 307 fixedly connected to the self-powered component 2. A sound generator 304 is fixedly connected to the center of the support shell 307, and a bearing shell 303 is provided along the sound emission path of the sound generator 304. The carrier shell 303 is rotatably mounted on the support shell 307. The carrier shell 303 is provided with multiple blocking plates 302. The multiple blocking plates 302 are made of different materials, so that the wavelength of the ultrasonic waves emitted by the sound generator 304 changes after passing through different blocking plates 302. The blocking plates 302 are set to correspond to the sound emission path of the sound generator 304, so that the ultrasonic waves emitted by the sound generator 304 can stably pass through the corresponding blocking plates 302. The outer periphery of the carrier shell 303 is provided with multiple wind turbine blades 301. When the wind blows and the wind turbine blades 301 drive the carrier shell 303 to rotate, the multiple blocking plates 302 will pass through the sound generator 304 one by one, thereby changing the wavelength of the sound emitted by the sound generator 304 after passing through the corresponding blocking plate 302. That is, the sound generator 304 emits ultrasonic waves of different wavelengths to repel birds. At the same time, the wavelength of the emitted ultrasonic waves is controlled by irregular wind force, so it can effectively reduce the situation where birds easily adapt to the use of ultrasonic waves of the same wavelength for a long time, resulting in a significant reduction in the bird repelling effect.

[0022] Specifically, the carrier shell 303 is provided with multiple through holes, which are engaged with the blocking plate 302 to facilitate the replacement of the blocking plate 302 by the staff. This allows for easy modification of the structural settings to improve the bird-repelling effect after the birds' adaptability increases and the bird-repelling effect decreases. At the same time, it also allows the ultrasonic waves emitted by the generator 304 to directly pass through the blocking plate 302 to change their own wavelength. Specifically, the blocking plate 302 is made of iron-based, nickel-based, or cobalt-based alloy materials. The different base alloys have different hardness, toughness, and other mechanical properties. When the ultrasonic waves propagate through them, the energy attenuation and scattering are different, which will cause the wavelength of the ultrasonic waves to change during the propagation process.

[0023] The positioning component 1 includes two annular connecting tiles 101. Specifically, the connecting tiles 101 have a central arch and ear plates on both sides. The ear plates of the two connecting tiles 101 are connected by locking pins 102 to stably connect the power transmission line with the cooperation of the two central arches. This helps to fix the auxiliary self-powering component 2 and the bird-repelling component 3 to the power transmission line. When the wind blows the fan blades 301 and causes the bearing shell 303 to rotate, it maintains the stability of the support shell 307 in the position on the power transmission line. Each of the two connecting tiles 101 has a clamping ring 103 on its opposite surface with a central arch. The clamping ring 103 is made of insulating rubber to protect the surface of the power transmission line while the connecting tiles 101 clamp the power transmission line. At the same time, the clamping ring 103 can also improve the connection stability between the power transmission lines based on the clamping force provided by the connecting tiles 101.

[0024] A rotating rail 305 is fixedly provided on the outer circumference of the support shell 307. A rotating ring 306 fixed on the bearing shell 303 is rotatably connected inside the rotating rail 305. Specifically, the rotating rail 305, the rotating ring 306 and the bearing shell 303 are all C-shaped, and the notch of the rotating ring 306 is smaller than the notch of the rotating rail 305. This ensures that the multiple baffles 302 on the bearing shell 303 can rotate stably while reducing the weight of the rotating rail 305, the rotating ring 306 and the bearing shell 303. Then, under the push of the wind, they can pass irregularly on the sound path of the sound generator 304, and then the frequency of the sound emitted by the sound generator 304 can be changed irregularly. The C-shaped design also makes it easy for workers to install and remove the rotating rail 305, the rotating ring 306 and the bearing shell 303 on the power transmission line.

[0025] In practical use, first connect the self-powered assembly 2 to the power transmission line. Then, secure the two corresponding connecting tiles 101 to the power transmission line using locking pins 102. Next, stably position the support shell 307 on the power transmission line. Simultaneously, the self-powered assembly 2 will use a current transformer to induce electrical energy from the power transmission line to provide power to the sound generator 304 mounted on the support shell 307. After the sound generator 304 operates, it will emit ultrasonic waves to drive away birds standing on the power transmission line. While the sound generator 304 emits ultrasonic waves to drive away birds, the wind will also work in conjunction with the device. The wind turbine blades 301 on the outer periphery of the carrier shell 303 drive the carrier shell 303 to rotate irregularly in cooperation with the rotating rail 305 and the rotating ring 306. Then, multiple blocking plates 302 set on the carrier shell 303 will pass through the sound path of the sound generator 304 one by one irregularly. That is, multiple blocking plates 302 will cover the ultrasonic wave emission point of the sound generator 304 one by one. Then, the emitted ultrasonic wave can be passed through blocking plates 302 of different materials to change the wavelength of the ultrasonic wave, so that the characteristics of the ultrasonic wave will change continuously, reduce the speed at which birds adapt to the ultrasonic wave, and make the bird repelling effect more lasting.

It should be understood that this utility model is not limited to the specific embodiments described above, and those skilled in the art can make various modifications or variations within the scope of the claims, which do not affect the substantive content of this utility model.
