Description

Technical Field

[0001] This utility model relates to the field of power systems, specifically to a three-sided ultrasonic bird deterrent for iron towers. Background Technology

[0002] In the field of power engineering, transmission towers, as key supporting facilities for power transmission, are frequently affected by birds roosting and nesting, leading to faults such as bird droppings contaminating insulators and short circuits in bird nest materials, threatening the stable operation of the power system. Ultrasonic bird deterrents, which emit ultrasonic waves of specific frequencies to interfere with birds, have become a commonly used method of bird control.

[0003] Ideally, ultrasonic bird repellers should be perpendicular to the tower to ensure effective coverage of the surrounding area and achieve a good bird-repelling effect. However, in reality, the angle steel of the tower is often tilted. When the angle steel is tilted, traditional bird repeller installation structures are difficult to adapt to this tilt angle. If forced to install, the bird repeller cannot maintain a proper perpendicular posture to the tower. It may become unstable and easily loosen or fall off under the influence of wind or other external forces; or the ultrasonic wave propagation direction may deviate from the expected direction, resulting in misaligned and incomplete bird-repelling coverage, significantly reducing its effectiveness and making it difficult to effectively prevent birds from adversely affecting the tower and power facilities. Therefore, a new installation structure that can adapt to the tilt of the angle steel and ensure a reasonable installation angle for the bird repeller is urgently needed to solve this practical application problem. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention aims to provide a three-sided ultrasonic bird repeller for power towers. It can flexibly adapt to the tilt of the tower's angle steel, adjust the angle of the bird repeller to ensure effective ultrasonic coverage, and guarantee stable installation, providing long-term reliable bird repeller operation and ensuring the safe operation of power towers.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a three-sided ultrasonic bird repeller for iron towers, comprising a fixed mounting base and a movable mounting base connected to the fixed mounting base; a mounting bracket is fixed to the upper end of the movable mounting base, and three sets of ultrasonic bird repellers are evenly distributed in a ring at the upper end of the mounting bracket; a bolt locking block is connected to the bottom of the fixed mounting base, and a locking strip is provided at the upper end of the bolt locking block. Preferably, a hinge hole is provided at the connection between the fixed mounting base and the movable mounting base, and an arc-shaped groove for adjusting the angle is provided at the upper end of the hinge hole. The fixed mounting base and the movable mounting base are fixed at an angle by bolts passing through the hinge hole and the arc-shaped groove.

[0006] Preferably, the mounting bracket includes a three-piece support section, with a downwardly bent mounting section at the bottom of the support section. The mounting section is fixedly connected to the upper end of the movable mounting seat by bolts, and a U-shaped connecting section is provided at the end of the support section.

[0007] Preferably, the ultrasonic bird repeller has side wings on both sides, and the side wings of two adjacent sets of ultrasonic bird repellers are fitted together and fixedly connected by bolts, with the bottom of the side wings fixedly connected to the connecting part.

[0008] Preferably, the lower surface of the fixed mounting base is symmetrically provided with length adjustment grooves, and the bolt locking block can move along the extension direction of the length adjustment groove to adjust the installation position.

[0009] Preferably, the front end of the fixed mounting base is bent downward to form a snap-fit ​​portion, which is used to snap-fit ​​with the angle iron of the tower.

[0010] (III) Beneficial Effects This utility model has the following beneficial effects: In terms of installation adaptability, the hinge and arc groove design of the fixed mounting base and the movable mounting base, together with the movable bolt locking block and snap-fit ​​part, can flexibly adapt to complex working conditions such as the tilt of the angle steel of the iron tower. No matter what the tilt angle of the angle steel is, the posture of the bird repeller can be precisely adjusted to ensure that the ultrasonic wave propagation direction is reasonable, and solve the problems of angle deviation and unstable installation of the bird repeller caused by the tilt of the angle steel in traditional installation.

[0011] In terms of bird deterrence effectiveness, the core component, the ultrasonic bird deterrent, integrates an infrared pyroelectric sensor and a Fresnel lens for precise bird detection. Combined with four square-distributed ultrasonic horns and a V-shaped flashing light, it forms a synergistic sound and light bird deterrence mechanism, which is more deterrent than traditional single-method bird deterrence. It effectively avoids bird adaptation issues and significantly improves bird deterrence efficiency. Meanwhile, the mounting bracket and bird deterrent are securely connected via side wings and connecting parts, ensuring structural reliability for long-term outdoor use. This reduces maintenance costs caused by equipment loosening or displacement, providing durable and efficient bird protection for the stable operation of power transmission towers. It also helps reduce safety hazards caused by bird interference in the power engineering field, improving the efficiency and stability of power system operation and maintenance.

Detailed Implementation

[0019] The following will refer to the appendix in the example of this utility model. Figures 1-6 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Example 1: like Figure 1-4 As shown in the figure, this embodiment provides a three-sided ultrasonic bird repeller for iron towers, including a fixed mounting base 1 and a movable mounting base 2 connected to the fixed mounting base 1; the upper end of the movable mounting base 2 is fixed with a mounting bracket 3, and three sets of ultrasonic bird repellers 4 are evenly distributed in a ring on the upper end of the mounting bracket 3; the bottom of the fixed mounting base 1 is connected with a bolt locking block 5, and the upper end of the bolt locking block 5 is provided with a locking strip 6.

[0021] Among them, the fixed mounting base 1 is the basic load-bearing and connecting component of the entire bird deterrent device, undertaking multiple key functions. On the one hand, it provides a connecting support base for the movable mounting base 2. By cooperating with the movable mounting base 2 and using the hinge hole 11, the two are hinged together, allowing the movable mounting base 2 to rotate around the hinge point. With the help of the arc groove 12 and the through bolts, the angle of the movable mounting base 2 relative to the fixed mounting base 1 can be flexibly adjusted, thereby adapting to different installation scenarios and angle requirements of the iron tower and ensuring that the bird repeller can accurately face the required protection direction. On the other hand, the bottom is connected to the bolt locking block 5, and the length adjustment groove 13 set on the lower surface provides the bolt locking block 5 with the space for movement adjustment, so that the bolt locking block 5 can move along the extension direction of the groove. This makes it easy to adjust the overall installation position of the device on the iron tower according to the actual structure of the iron tower, improving the installation adaptability. At the same time, the snap-fit ​​part 14 formed by the downward bending of the front end can be snapped together with the iron tower angle iron. Working together with the bolt locking block 5, the entire bird repeller is firmly installed on the iron tower, enhancing the structural stability of the device after installation and preventing loosening or displacement due to external forces such as wind.

[0022] The movable mounting base 2 mainly serves as a connector and angle adjustment transition. Its upper end is used to fix the mounting bracket 3, providing an upper support carrier for the installation of the bird repeller. It is connected to the fixed mounting base 1 through the hinge hole 11 and the arc groove 12 with bolts. During the installation process, it can flexibly adjust its angle relative to the fixed mounting base 1 according to the tower site environment and bird protection requirements. In this way, it can adjust the mounting bracket 3 and ultrasonic bird repeller 4 installed on it to the optimal bird repeller angle, ensuring accurate and effective ultrasonic coverage and improving the bird repeller effect.

[0023] The mounting bracket 3 serves as the direct mounting carrier for the ultrasonic bird repeller 4. Its three-piece support section 31 provides mounting positions for the three sets of ultrasonic bird repellers 4 in a uniformly distributed ring, ensuring a three-sided layout and providing comprehensive ultrasonic coverage protection around the tower. The mounting section 32, bent downwards at the bottom, has a bolt welded to its center. This bolt securely connects the mounting bracket 3 to the upper end of the movable mounting base 2, providing reliable support for the entire bird repeller assembly. The U-shaped connecting section 33 at the end of the support section 31 connects with the side wings 42 of the ultrasonic bird repeller 4, providing mounting points and ensuring structural stability after installation. This prevents shaking or detachment and ensures stable ultrasonic wave transmission.

[0024] The bolt locking block 5 and the locking strip 6 work together to lock the entire bird deterrent device onto the tower structure. The bolt locking block 5 can move along the length adjustment groove 13 of the fixed mounting base 1. After being adjusted to a suitable position, it works with the locking strip 6 and other fasteners such as bolts to lock the device onto the tower structure, such as angle steel. Together with the snap-fit ​​part 14 of the fixed mounting base 1, the device is secured from different parts, ensuring that the entire bird deterrent device can be firmly installed on the tower, withstand the influence of outdoor wind, vibration and other external forces, maintain the structural stability of the device after installation, and ensure the continuous and stable operation of the bird deterrent function.

[0025] like Figures 5-6 As shown, the ultrasonic bird repeller 4 is the core component for achieving the bird repeller function. The ultrasonic bird repeller 4 includes a housing 41. Four sets of ultrasonic speakers 43 are embedded in the front of the housing 41 in a square arrangement. A Fresnel lens 44 is embedded in the upper part of the housing 41. An infrared pyroelectric sensor 45 is fixed inside the housing 41 at the position corresponding to the Fresnel lens 44, and the Fresnel lens 44 and the infrared pyroelectric sensor 45 are coaxially aligned, so that the infrared signal focused by the Fresnel lens 44 is projected onto the sensing surface of the infrared pyroelectric sensor 45. A V-shaped strobe light 46 is provided at the upper front of the housing 41. A photovoltaic panel 47 is inclinedly installed on the top of the housing 41. A boat-shaped switch 48 and an indicator light 49 are provided at the bottom of the housing 41.

[0026] The housing 41 serves as the main structural component of the ultrasonic bird repeller 4, providing a mounting platform and protective shell for the various internal and external functional components. Its overall structural design protects internal precision components such as the infrared pyroelectric sensor 45 from outdoor wind, rain, dust, and external impacts. At the same time, it provides a stable assembly base for external components such as the ultrasonic horn 43 and Fresnel lens 44, ensuring that each component maintains a stable relative position in complex outdoor environments and guaranteeing the reliable operation of the bird repeller's overall function.

[0027] The four sets of ultrasonic speakers 43 embedded in the front of the housing 41 are arranged in a square pattern and are the core actuators for realizing the ultrasonic bird-repelling function. During operation, the four speakers synchronously emit ultrasonic waves of a specific frequency, utilizing the interference of ultrasonic waves on the birds' auditory system to disrupt their habitat and create an auditory deterrent. The square arrangement expands the coverage of the ultrasonic waves, ensuring that the bird-repelling signal forms a complete sound barrier in front of the housing, enhancing the bird-repelling effect.

[0028] The Fresnel lens 44 is mounted on the upper part of the housing 41. Its core function is to focus infrared radiation signals from the external environment, converging the dispersed infrared energy and projecting it directionally onto the internal infrared pyroelectric sensor 45. The coaxial alignment of the two ensures that the focused infrared signal is accurately projected onto the sensor's sensing surface, significantly improving the sensor's sensitivity and detection range for live targets such as birds.

[0029] The infrared pyroelectric sensor 45 serves as the core of the detection system. It can sense changes in the infrared signal focused by the Fresnel lens 44. When warm-blooded animals such as birds enter the detection range, the infrared radiation they release will trigger the sensor to generate an electrical signal, thereby achieving accurate identification and triggering response to bird activities.

[0030] The V-shaped strobe light 46 at the upper front of the housing 41 is a key component for visual bird deterrence. When the infrared pyroelectric sensor 45 detects a bird, the V-shaped strobe light will activate synchronously, emitting a high-frequency flashing bright light. Utilizing birds' instinctive fear of bright light and rapid changes in brightness, it creates a strong visual impact. Working in conjunction with the ultrasonic speaker 43, it enhances the deterrent effect on birds from both visual and auditory dimensions, thereby improving the bird deterrence effect.

[0031] The photovoltaic panel 47, tilted at the top of the casing 41, is the energy supply component of the device. It absorbs solar energy and converts it into electrical energy, providing continuous power to the various functional components of the ultrasonic bird repeller 4, such as the ultrasonic horn, strobe light, and sensors. The tilted design optimizes the angle of sunlight reception, improves light energy conversion efficiency, and ensures long-term stable operation of the device in outdoor environments without the need for an external power source, adapting to installation requirements in scenarios without mains power supply, such as those involving iron towers.

[0032] The rocker switch 48 features dual-mode control, allowing for flexible switching of operating states based on actual usage scenarios. When the switch is set to the "delay" position, the device immediately enters a 30-minute delay start-up mode. At this time, the indicator light flashes red once every two seconds, providing clear feedback that the device is in standby mode. This design is primarily used during the installation and commissioning phase, effectively preventing accidental triggering of ultrasonic waves or strong light during installation, thus avoiding interference with installers and ensuring smooth installation operations. When the switch is set to the "operation" position, the device immediately activates all functions, and the indicator light switches to a solid green. In this mode, the infrared pyroelectric sensor 45, ultrasonic horn 43, and V-shaped strobe light 46 are all in standby mode, facilitating on-site testing by installers to ensure the device's sensitivity, sound wave emission, and light flashing are functioning correctly, guaranteeing stable bird-repelling performance after installation. This dual-mode control design balances convenience and safety during installation while providing clear status indicators for device function testing, significantly improving the device's practicality and ease of operation.

[0033] The side wings 42 on both sides of the ultrasonic bird repeller 4 connect the three bird repellers into a stable whole by the side wings 42 of the adjacent bird repellers fitting together and being fixed with bolts, thereby enhancing the structural strength of the component; on the other hand, the bottom of the side wings 42 is fixed to the connection part 33 of the mounting bracket 3, ensuring that the bird repeller is firmly assembled on the mounting bracket 3, and ensuring the stable performance of the sensing, light-up and ultrasonic functions during long-term outdoor use.

[0034] Working principle: During the installation phase, the fixed mounting base 1 engages with the angle iron of the tower via the snap-fit ​​part 14, and with the bolt locking block 5 adjusting the position along the length adjustment groove 13 and the tightening of the locking strip 6, a stable overall installation is achieved; the fixed mounting base 1 and the movable mounting base 2 are hinged through the hinge hole 11, and with the positioning of the bolt in the arc groove 12, the angle can be flexibly adjusted to ensure that the three sets of ultrasonic bird repellers 4 on the mounting bracket 3 are in the optimal detection and bird repeller positions.

[0035] The ultrasonic bird repeller 4 is the core actuator, and its working process is as follows: The photovoltaic panel 47, which is tilted at the top, continuously supplies power to the device. After being started by the bottom boat-shaped switch 48, the indicator light 49 displays the working status. The rocker switch 48 features dual-mode control: when switched to the "delay" position, the device enters a 30-minute delay state, and the indicator light flashes red once every 2 seconds to avoid interfering with personnel during installation; when switched to the "work" position, the device starts immediately, and the indicator light remains solid green for easy function testing.

[0036] The Fresnel lens 44 on the upper part of the housing 41 focuses the external infrared signal and projects it onto the internal coaxially aligned infrared pyroelectric sensor 45, so as to achieve accurate detection of bird activity around the tower.

[0037] When birds are detected, the bird deterrent device immediately activates a dual bird deterrent mechanism: four sets of square-distributed ultrasonic speakers 43 at the front simultaneously emit ultrasonic waves of a specific frequency, forming a dense sound barrier; the V-shaped flashing lights 46 at the upper front simultaneously emit strong flashing light, deterring birds from both auditory and visual perspectives. The three sets of bird deterrent devices are fixed together in a ring shape by the side wings 42, and together with the three-piece support 31 of the mounting bracket 3, they form a 360° three-dimensional protective area, forcing birds away from the tower and effectively preventing power outages caused by birds roosting and nesting, thus achieving highly efficient bird deterrence and protection.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
