Description

Technical Field

[0001] This utility model relates to the technical field of bird deterrent devices, and in particular to a sonic bird deterrent device for power facilities. Background Technology

[0002] In the power infrastructure sector, bird activity poses a significant threat to the safe and stable operation of power facilities. When birds nest, roost, or fly over power facilities such as transmission lines and substations, their droppings can cause faults such as insulator flashovers. Nest materials can also cause short circuits in windy and rainy weather. Furthermore, bird strikes can directly damage power equipment, causing power outages or even fires. Therefore, effectively deterring birds and ensuring the safe operation of power facilities has become a crucial issue that the power industry urgently needs to address.

[0003] Currently, various bird protection methods exist on the market, among which acoustic bird deterrent technology has attracted much attention due to its environmentally friendly and efficient characteristics. Acoustic bird deterrent technology emits sound waves of specific frequencies and waveforms to induce discomfort or fear in birds, thereby driving them away. However, existing acoustic bird deterrents still have some shortcomings in practical applications.

[0004] Many sonic boom detectors emit sound waves in a fixed direction, making it impossible to adjust them flexibly according to bird activity patterns and the specific layout of power facilities. This means that in some cases, the sound waves may not effectively cover areas where birds are frequently active, thus reducing their bird-repelling effect. Utility Model Content

[0039] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0040] See Figure 1-3 As shown;

[0041] The acoustic bird protector for power facilities according to this embodiment of the utility model includes:

[0042] Support base 1 is supported and set on the ground, and a rotation drive assembly is installed inside the support base 1;

[0043] The rotating base plate 11 is rotatably mounted on the support base 1 and is driven to rotate by the rotation drive assembly;

[0044] An angle adjustment mechanism is set on the rotating base plate 11 and is used to drive the sound wave generator to adjust the angle;

[0045] The angle adjustment mechanism includes:

[0046] The transmission bracket 21 is fixedly installed on the rotating base plate 11;

[0047] The swing support 22 is fixedly installed on the transmission bracket 21;

[0048] The swing shaft 23 is rotatably inserted into the swing support 22;

[0049] The swing rod 24 is fixedly connected to the swing shaft 23 and swings through the swing shaft 23. A sound wave generator 25 is provided at the top of the swing rod 24.

[0050] The drive component is used to drive the sound wave generator 25 to swing and adjust.

[0051] By adopting the above technical solution, when the sonic bird protector for power facilities is put into use, firstly, the support base 1 is firmly set on the ground, providing a solid foundation for the entire device; when it is necessary to adjust the direction of sonic emission, the rotation drive component inside the support base 1 is activated, which drives the rotating base plate 11 to rotate on the support base 1, realizing the angle adjustment of the protector in the horizontal direction to cover the bird activity area in different directions; if it is necessary to further adjust the vertical emission angle of the sonic wave, the angle adjustment mechanism begins to function; the drive component is activated, transmitting power to the swing shaft 23 through the transmission bracket 21; the swing shaft 23 rotates on the swing support 22, driving the swing rod 24 fixedly connected to it to swing; since a sonic generator 25 is set at the top of the swing rod 24, the swing of the swing rod 24 will cause the sonic generator 25 to change its angle in the vertical direction; through the synergistic action of the rotation drive component and the angle adjustment mechanism, the sonic wave is generated The device 25 can flexibly adjust its angle in both horizontal and vertical directions, allowing the emitted sound waves of specific frequencies and waveforms to precisely cover areas where birds are frequently active, effectively driving away birds. The rotating drive component and angle adjustment mechanism of the device enable flexible adjustment of the sound wave generator 25 in both horizontal and vertical directions. Based on the activity patterns of birds in different locations of power facilities such as power transmission lines and substations, as well as the specific layout of the power facilities, the device can accurately project sound waves onto areas where birds gather, effectively improving the bird-repelling effect and reducing the risk of power facility failures caused by bird activity. The flexibly adjustable sound wave emission angle allows the device to quickly adapt to different environments and changes in bird activity. Without the need for frequent manual adjustments to the device position, it can continuously maintain effective bird repellency. Compared with traditional fixed-direction sound wave protectors, this greatly improves bird-repelling efficiency, reduces the number of power facility failures caused by bird activity, and ensures the safe and stable operation of power facilities.

[0052] As a preferred embodiment of the above technical solution, such as Figure 2 As shown, the driving component includes:

[0053] The second worm gear 26 is rotatably mounted on the transmission bracket 21, and the second worm gear 26 is driven by a motor.

[0054] The second worm gear 27 is rotatably mounted on the transmission bracket 21, and the second worm gear 27 meshes with the second worm 26;

[0055] The transmission gear 28 is rotatably mounted on the swing support 22 and is driven to rotate by the second worm gear 27.

[0056] Driven gear 29 is fastened to the swing shaft 23 and meshes with transmission gear 28, and is driven to rotate by transmission gear 28;

[0057] In this embodiment, when the acoustic bird protector for power facilities needs to adjust the angle of the acoustic generator 25 in the vertical direction, the drive assembly starts to operate; the motor starts, driving the second worm 26 to rotate on the transmission bracket 21. The second worm 26, as the driving element, outputs the rotational power of the motor; since the second worm wheel 27 meshes with the second worm 26, according to the worm gear transmission principle, the rotation of the second worm 26 will drive the second worm wheel 27 to rotate on the transmission bracket 21, realizing the first power transmission and deceleration and torque increase; when the second worm wheel 27 rotates, it drives the transmission gear 28 linked with it to rotate on the swing support 22, completing the second power transmission; the transmission gear 28, as the driving gear, meshes with the driven gear 29 fastened to the swing shaft 23, and transmits power to the driven gear 29 through gear transmission. 9. This drives the swing shaft 23 to rotate on the swing support 22. Because the swing rod 24 is fixedly connected to the swing shaft 23, the rotation of the swing shaft 23 will drive the swing rod 24 to swing, thereby changing the angle of the sound wave generator 25 at the top of the swing rod 24 in the vertical direction, thus adjusting the sound wave emission angle. The worm gear transmission has self-locking properties, which can reliably maintain the angle of the sound wave generator 25 after the angle is adjusted to the correct position, preventing angle deviation due to external interference and ensuring the stability of the sound wave emission direction. At the same time, the gear transmission has the characteristic of accurate transmission ratio. By reasonably designing the number of teeth of the transmission gear 28 and the driven gear 29, the rotation angle of the swing shaft 23 can be precisely controlled, thereby accurately adjusting the vertical emission angle of the sound wave generator 25, so that the sound waves can more accurately cover the bird activity area and improve the bird deterrence effect.

[0058] As a preferred embodiment of the above technical solution, such as Figure 2 As shown, the rotary drive assembly includes:

[0059] The rotary motor 12 is fixedly installed in the support base 1;

[0060] The first worm gear 13 is rotatably mounted in the support base 1 and is driven to rotate by the rotary motor 12;

[0061] A support shaft 14 is vertically rotatably installed in a support base 1, and the top end of the support shaft 14 is fastened to the bottom end of the rotating base plate 11.

[0062] The first worm gear 15 is fastened to the support shaft 14, and the first worm gear 15 meshes with the first worm 13;

[0063] In this embodiment, when it is necessary to adjust the angle of the sound wave generator 25 in the horizontal direction, the rotary drive assembly starts to work; the rotary motor 12 starts, which is fixedly installed in the support base 1 and provides power to the entire rotary drive assembly; the rotary motor 12 drives the first worm gear 13 connected to it to rotate in the support base 1; the first worm gear 13, as the driving member, meshes with the first worm wheel 15, which is fastened to the support shaft 14; due to the characteristics of worm gear transmission, the rotation of the first worm gear 13 will cause the first worm wheel 15 to rotate; the support shaft 14 is vertically rotatably installed in the support base 1, and its top end is fastened to the bottom end of the rotating base plate 11; therefore, when the first worm wheel 15 rotates, it will drive the support... The rotating shaft 14 rotates together, thereby driving the rotating base plate 11 to rotate horizontally around the central axis of the support base 1. As the rotating base plate 11 rotates, the angle adjustment mechanism and the sound wave generator 25 installed on it will also change their positions in the horizontal direction accordingly, thereby adjusting the sound wave emission direction on the horizontal plane to better cover areas where birds are frequently active. Through the action of the rotation drive component, the sound wave generator 25 can be flexibly rotated in the horizontal direction. The emission direction of the sound wave can be precisely adjusted according to the layout of the power facilities and the activity of birds in different directions, ensuring that the sound wave can fully cover areas that may be threatened by birds, effectively improving the targeting and effect of bird deterrence.

[0064] As a preferred embodiment of the above technical solution, such as Figure 3 As shown, a plurality of balls 16 are arranged in a circular pattern at the top of the support base 1. The balls 16 are all rolled on the support base 1. The balls 16 are used to support the entire rotating base plate 11 and roll in contact with the bottom surface of the rotating base plate 11.

[0065] In this embodiment, the balls 16 are evenly distributed around the top of the support base 1, and their tops are in direct contact with the bottom surface of the rotating base plate 11, forming a rolling support structure. When the rotating drive assembly is started, the support shaft 14 drives the rotating base plate 11 to rotate around the vertical axis. When the rotating base plate 11 rotates, its bottom surface and the balls 16 make rolling contact. The balls themselves can roll freely in the grooves or tracks of the support base 1, converting the sliding friction of the rotating base plate into the rolling friction of the balls. The rolling friction coefficient is significantly lower than that of traditional sliding friction, making the rotating base plate rotate more flexibly, reducing motor energy consumption, and extending the life of the drive components. The weight of the rotating base plate 11 and the load of the components above it are evenly transmitted to the support base 1 through the balls 16, avoiding excessive local stress.

[0066] As a preferred embodiment of the above technical solution, such as Figure 1 As shown, a protective shell 2a is provided on the rotating base plate 11. The protective shell 2a covers the outside of the drive assembly. The protective shell 2a is provided with a swing groove to allow the swing rod 24 to swing smoothly.

[0067] In this embodiment, the protective shell isolates the drive components from the external environment, preventing bird droppings, rainwater, dust, etc. from entering the transmission mechanism, preventing gear meshing parts from jamming, rusting, or transmission failure due to contamination, and extending the service life of the equipment; physical shielding can prevent accidental contact by personnel, animal gnawing, or foreign object impact on the drive components, which is especially suitable for complex outdoor environments; the swing groove ensures that the swing rod 24 is not obstructed by the protective shell when adjusting the angle, realizing flexible adjustment of the pitch angle of the sound wave generator 25.

[0068] As a preferred embodiment of the above technical solution, such as Figure 1 As shown, a dustproof rubber strip 2b is provided on the swing groove of the protective shell 2a;

[0069] In this embodiment, the dustproof rubber strip 2b is fixedly installed on the edge of the swing groove of the protective shell 2a. Its material is elastic and it fits tightly against the outer wall of the swing rod 24. When the swing rod 24 is adjusted in angle under the action of the drive component, it swings back and forth along the swing groove. At this time, the rubber strip maintains dynamic sealing contact with the swing rod through its own elastic deformation, forming a flexible barrier. The protective shell 2a is completely covered on the outside of the drive component, forming a physical protective space. The swing groove serves as the movement channel of the swing rod 24, and the dustproof rubber strip 2b on its edge fills the gap between the swing rod and the groove. During the movement of the swing rod, the rubber strip bends or compresses with its swing direction, always covering the gap and preventing external dust, rainwater and other foreign objects from entering the interior of the protective shell.

[0070] As a preferred embodiment of the above technical solution, such as Figure 1 As shown, a sound collecting cover 2c is provided on the swing rod 24, and the sound collecting cover 2c covers the sound wave generator 25;

[0071] In this embodiment, sound wave energy is concentrated in a specific direction through physical structure to avoid ineffective diffusion, thereby increasing the sound pressure level per unit area and enhancing the stimulation effect on birds. With the horizontal rotation of the rotating base plate 11 and the angle adjustment of the swing rod 24, the sound collecting cover can achieve sound beam pointing adjustment in three-dimensional space, accurately covering areas where birds are frequently active, and solving the coverage blind spot problem of traditional fixed-direction sound wave protectors. The directional sound waves only act on the target area, reducing sound pollution to non-target areas such as surrounding residential areas and ecological protection areas, which meets environmental protection requirements. Compared with omnidirectional sound-emitting devices, the sound collecting cover can reduce the power requirement of the sound wave generator by concentrating energy, reducing energy consumption under the same repelling effect, extending the equipment's battery life or reducing power consumption.

[0072] As a preferred embodiment of the above technical solution, a shock-absorbing pad is provided at the bottom of the support base 1;

[0073] In this embodiment, the shock-absorbing pad can buffer and absorb vibrations through its own elastic material properties: when the rotary motor 12 drives the first worm gear 13 to rotate, the vibration generated by the mechanical transmission will first act on the bottom end of the support. The shock-absorbing pad consumes the vibration energy through elastic deformation, reducing the transmission of vibration to the ground, and at the same time reducing the impact of vibration on the precision transmission components inside the protector; when the vibration of the external environment is transmitted to the support through the ground, the elastic structure of the shock-absorbing pad can effectively weaken the vibration amplitude, preventing the protector from displacement or loosening of components due to severe vibration.

[0074] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
