Description

Technical Field

[0001] This utility model relates to the field of power facility protection technology, specifically to a bird deterrent device for power transmission towers. Background Technology

[0002] Power transmission towers, serving as the supporting structures for high-voltage transmission lines, are mostly erected in open, outdoor areas. Due to their complex structures and numerous perching platforms, they easily become nesting and roosting sites for birds. Bird activity can lead to problems such as short circuits in transmission lines and corrosion of tower components (due to bird droppings), seriously threatening the safe and stable operation of the power system.

[0003] To address the aforementioned issues, various bird deterrent devices have emerged in the existing technology, but they still have significant drawbacks in practical applications. For example, ultrasonic bird deterrent devices rely on electric power, which not only requires regular battery replacement or connection to an external power source, increasing maintenance costs, but also makes ultrasonic signals susceptible to interference from complex outdoor environments (such as wind, rain, and obstacles), limiting the bird deterrent range and effectiveness. Furthermore, birds may develop adaptation after long-term use, leading to bird deterrent failure. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a bird deterrent device for power transmission towers, so as to solve the problems of high dependence, poor adaptability and high maintenance cost of existing bird deterrent devices.

[0005] According to an embodiment of the present utility model, a bird deterrent device for power transmission towers includes a housing, which is cylindrical and has a front baffle and a rear baffle respectively provided at the front and rear openings. A sound-generating unit, which includes a sound-generating component and a driving component; The sound-generating component includes a sound-generating ring disposed within the housing and multiple sets of striking elements evenly distributed on the rear baffle, with each striking element located within the sound-generating ring. The driving component includes a fan blade rotatably mounted on the front baffle and a driving ring disposed in the housing and connected to the fan blade in a transmission manner. The driving ring is used to drive the striking component to strike the sound-producing ring. The mounting unit, located on the housing, is used to mount the housing onto the power tower.

[0006] Compared to existing technologies, this invention offers the following advantages: Driven by natural wind energy, the fan blades rotate to power a mechanical transmission structure (drive ring and striking components), eliminating the need for external power or reliance on specific conditions such as sunlight, thus completely freeing it from limitations imposed by energy supply and environmental factors. Through the cooperation of the drive ring and multiple sets of striking components, the drive ring periodically drives different striking components to intermittently strike the sound-producing ring during fan blade rotation, creating irregular sound waves with varying frequencies and rhythms. This effectively prevents birds from developing adaptive behavior. Furthermore, the purely mechanical design is unaffected by weather, ensuring stable operation regardless of sunshine, rain, day, or night, adapting to complex and changing outdoor environments. Moreover, the use of entirely mechanical components results in high durability, the absence of electronic components or easily consumable materials, and a low failure rate.

[0007] Preferably, each striking element includes a mounting base inclinedly disposed on the rear baffle and a spring disposed on the mounting base, the end of the spring being provided with a striking head for striking the sound-producing ring.

[0008] Preferably, a drive gear is provided at one end of the fan blade near the striking element, a rotating shaft is rotatably provided on the front baffle, the other end of the rotating shaft is rotatably provided on the rear baffle, a driven gear is provided at one end of the rotating shaft near the fan blade, the driven gear meshes with the drive gear, and a drive ring is provided on the rotating shaft.

[0009] Preferably, the drive ring includes a turntable fixedly mounted on a rotating shaft, and multiple sets of wedge blocks evenly distributed along the circumference of the turntable. The wedge blocks are used to abut against the striking head of the driving striking element, wherein the turntable is coaxially arranged with the sound-generating ring and the housing.

[0010] Preferably, multiple sets of through slots are provided on the rear baffle.

[0011] Preferably, a retaining rim is provided at one end of the housing near the rear baffle.

[0012] Preferably, a drainage groove is provided on the eaves.

[0013] Preferably, the installation unit includes a column mounted on the housing, a base connected to the bottom of the column, a slot on the base, and a screw threaded into the slot for locking the power tower components. Attached Figure Description

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figures 1 to 4 As shown in the figure, this utility model embodiment proposes a bird deterrent device for power towers, which includes a housing 20, the housing 20 is cylindrical, and a front baffle 21 and a rear baffle 22 are respectively provided at the front and rear openings. A sound-generating unit, which includes a sound-generating component and a driving component; The sound-generating component includes a sound-generating ring 60 disposed within the housing 20 and multiple sets of striking elements 50 evenly distributed on the rear baffle 22, with each striking element 50 located within the sound-generating ring 60. The driving component includes a fan blade 30 rotatably mounted on the front baffle 21 and a driving ring disposed in the housing 20 and pulsatorically connected to the fan blade 30. The driving ring is used to drive the striking component 50 to strike the sound-producing ring 60. The mounting unit is disposed on the housing 20 and is used to mount the housing 20 onto the power tower.

[0021] Driven by natural wind energy, the fan blades 30 rotate to power the mechanical transmission structure (drive ring and striking element 50), eliminating the need for external power supply or reliance on specific conditions such as sunlight, thus completely freeing it from limitations imposed by energy supply and environmental factors. Through the cooperation of the drive ring and multiple sets of striking elements 50, the drive ring periodically drives different striking elements 50 to intermittently strike the sound-producing ring 60 during the rotation of the fan blades 30, creating sound waves with irregular frequencies and rhythms. This effectively prevents birds from developing adaptations. Furthermore, the purely mechanical structure design is unaffected by weather, ensuring stable operation regardless of sunshine, rain, day, or night, adapting to the complex and ever-changing environment of the wild. Moreover, the use of all-mechanical components ensures high durability, eliminates electronic components or consumable materials, and results in a low failure rate.

[0022] In this embodiment, the sound-generating ring 60 is preferably made of copper alloy (such as brass) or aluminum alloy. Copper alloy has excellent acoustic properties, with moderate ductility and elastic modulus. When struck, it can produce high-frequency, crisp and loud sound waves with slow attenuation and wide propagation range, which can effectively stimulate the auditory system of birds. At the same time, copper alloy has strong corrosion resistance, is suitable for humid and dusty outdoor environments, and is not prone to sound production degradation due to rust after long-term use.

[0023] If aluminum alloy is chosen, it has a low density and sufficient strength, and it vibrates quickly when struck, producing a crisp high-frequency sound. It is also lightweight, which can reduce the overall load on the device. After surface anodizing, the weather resistance of aluminum alloy is significantly improved, which can adapt to complex outdoor climates and ensure stable long-term sound performance.

[0024] like Figure 3 As shown, each striking element 50 includes a mounting base 51 inclinedly disposed on the rear baffle 22 and a spring 52 disposed on the mounting base 51. The end of the spring 52 is provided with a striking head 53 for striking the sound ring 60.

[0025] The mounting base 51 is tilted on the rear baffle 22, which allows the striking head 53 to be precisely aligned with the inner sound ring 60, providing stable support for the striking action. The combination of the spring 52 and the striking head 53 forms an elastic transmission structure, which facilitates compression and energy storage when the drive ring (wedge block 40) contacts, and also enables rapid striking through the spring 52's reset, ensuring a crisp and powerful sound and improving the bird-repelling effect.

[0026] like Figure 2 As shown, a drive gear 31 is provided at one end of the fan blade 30 near the striking member 50, a rotating shaft 43 is rotatably provided on the front baffle 21, and the other end of the rotating shaft 43 is rotatably provided on the rear baffle 22. A driven gear 42 is provided at one end of the rotating shaft 43 near the fan blade 30. The driven gear 42 meshes with the drive gear 31, and a drive ring is provided on the rotating shaft 43.

[0027] The fan blade 30 is directly connected to the drive gear 31, converting wind energy into rotational power; the two ends of the rotating shaft 43 are respectively rotated and engaged with the front and rear baffles 22 to form a stable support structure, ensuring no obvious shaking during transmission; the meshing transmission between the drive gear 31 and the driven gear 42 stably transmits power to the rotating shaft 43, thereby driving the drive ring to work.

[0028] like Figure 2 and Figure 3 As shown, the drive ring includes a turntable 41 fixedly mounted on the rotating shaft 43, and multiple sets of wedge blocks 40 evenly distributed around the turntable 41. The wedge blocks 40 are used to abut against the striking head 53 of the drive striking member 50. The turntable 41 is coaxially arranged with the sound ring 60 and the housing 20.

[0029] The turntable 41 is fixedly connected to the rotating shaft 43 and is coaxially arranged with the housing 20 and the sound-emitting ring 60 to ensure concentricity during rotation, avoid wobbling or jamming due to eccentricity, and ensure transmission stability. Multiple sets of wedge blocks 40 are evenly distributed around the circumference of the turntable 41. When the turntable 41 rotates, they can sequentially abut against the striking head 53 of the striking element 50. The inclined structure of the wedge block 40 can smoothly push the striking head 53 to compress the spring 52 to store energy when in contact. When it is released, the spring 52's restoring force makes the striking head 53 quickly strike the sound-emitting ring 60, forming a continuous cycle of contact-energy storage-release-striking.

[0030] The evenly distributed design of multiple sets of wedge blocks 40, combined with the rotation of the turntable 41, can drive multiple sets of striking parts 50 to work alternately, generating sound waves with irregular frequencies and rhythms, thus preventing birds from adapting to a single sound.

[0031] like Figure 2 As shown, multiple sets of through slots 221 are provided on the rear baffle 22.

[0032] The through slot 221 serves as a sound propagation channel, allowing the crisp sound waves generated by striking inside the shell 20 to spread quickly and unobstructed to the external environment, avoiding sound wave reflection and attenuation within the enclosed shell 20, and expanding the effective bird-repelling range.

[0033] like Figure 2 As shown, a visor 23 is provided at one end of the housing 20 near the rear baffle 22. The visor 23 extends outward along the end of the housing 20 near the rear baffle 22 to form a shielding structure, which can directly intercept falling or drifting rainwater, preventing rainwater from seeping into the inner cavity of the housing 20 through the through groove 221, and protecting the mechanical parts such as gears, springs 52, and striking parts 50 inside the housing 20 from rainwater corrosion, and preventing rust or jamming.

[0034] like Figure 2 As shown, a drainage groove 231 is provided on the eaves 23. The drainage groove 231 prevents rainwater from accumulating at the eaves 23.

[0035] like Figure 1 As shown, the installation unit includes a column 11 mounted on the housing 20, a base 10 connected to the bottom end of the column 11, a slot 13 on the base 10, and a screw 12 for locking the power tower components threadedly connected to the slot 13.

[0036] The column 11 serves as the connecting carrier between the shell 20 and the base 10, raising the height of the device to ensure the wind-facing effect of the fan blade 30 and the range of sound wave propagation, while providing stable support for the shell 20. The slot 13 of the base 10 is designed to directly engage with crossbars, diagonal braces, and other components of different specifications on power towers without the need for additional drilling or welding, making it highly adaptable. The screw 12 at the slot 13 is locked by threads, and the clamping force can be adjusted according to the component size to achieve a firm fixation, preventing the device from loosening and falling off due to strong winds and vibrations in the field.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
