A biomimetic sound-based bird deterrent

Abstract

This utility model discloses a biomimetic sound-based bird deterrent device, including a mounting base. An outer support rod is connected to the center of the upper end of the mounting base, and a wind tunnel is connected to the upper end of the outer support rod. A connecting shaft is inserted into the upper end of the wind tunnel, and multiple connecting horizontal rods are connected to the upper end of the connecting shaft. Each of the multiple connecting horizontal rods has a connecting vertical rod connected to its outer side, and each of the multiple connecting vertical rods has a vertically upward-pointing biomimetic fan blade. The multiple biomimetic fan blades are all human-shaped. This utility model uses multiple rotationally symmetrical human-shaped biomimetic fan blades to rotate under the drive of wind, simulating human activity patterns. Combined with an up-and-down floating mechanism, it enhances the dynamic realism and achieves the dual effects of visual deterrence and physical deterrence. When the fan blades rotate under the drive of wind, a reverse airflow is generated inside the wind tunnel, pushing the connecting shaft to move up and down. With the help of the support spring, it forms an adaptive floating mechanism, using natural wind energy to achieve dynamic adjustment without power, thus improving the randomness and realism of the bird deterrent action.

Description

Technical Field

[0001] This utility model relates to the field of bird deterrents, and in particular to a bionic sound bird deterrent. Background Technology

[0002] Currently, bird activity often causes serious economic losses and safety risks in fields such as agriculture, airports, and power facilities. Traditional bird deterrence methods, such as manual deterrence, ultrasonic equipment, or static scarecrows, have problems such as low efficiency, poor adaptability, or easy habituation by birds.

[0003] Existing mechanical bird deterrent devices mostly use a single rotation or fixed action mode, lacking dynamic changes, which birds can easily adapt to; acoustic bird deterrent devices rely on external power supply or batteries, and have limited endurance in the wild environment.

[0004] To address the aforementioned issues, this patent proposes a highly efficient bird deterrent device that can simulate natural dynamics, combine sound and light for coordinated deterrence, possess self-powered capabilities, and has a durable mechanical structure. This addresses the problems of poor bird deterrent effect, high energy dependence, and insufficient mechanical reliability in existing technologies. Utility Model Content

[0005] The main purpose of this invention is to propose a biomimetic sound-based bird deterrent, which aims to solve the problem that traditional bird deterrents use a single rotation or fixed action mode, lack dynamic changes, and have poor bird deterrent effect.

[0006] To address the aforementioned problems, this utility model proposes a biomimetic sound-based bird deterrent device, comprising a mounting base, an outer support rod connected to the center of the upper end of the mounting base, a fan duct connected to the upper end of the outer support rod, a connecting shaft inserted into the upper end of the fan duct, multiple connecting horizontal bars connected to the upper end of the connecting shaft, connecting vertical bars connected to the outer sides of the upper ends of the multiple connecting horizontal bars, vertically upward biomimetic fan blades connected to the upper ends of the multiple connecting vertical bars, and multiple biomimetic fan blades arranged in a human-shaped manner and rotationally symmetrical about the central axis of the connecting shaft, photovoltaic panels arranged on the inner sides between the multiple connecting horizontal bars, an electrical box arranged at the upper end of the connecting shaft, a buzzer arranged at the upper end of the electrical box, and the electrical box electrically connected to the multiple photovoltaic panels and the buzzer via a wiring harness.

[0007] Preferably, the upper end of the outer support rod is connected to a limiting frame, and the connecting shaft passes through the center of the limiting frame and is slidably connected to the limiting frame. The lower end of the connecting shaft is connected to a connecting plate.

[0008] Preferably, multiple telescopic sliding rods are connected to the outer side of the lower end of the connecting plate, and an inner support rod is connected to the center of the inner wall of the lower end of the connecting shaft.

[0009] Preferably, the upper end of the inner support rod is rotatably connected to a spring support plate, and multiple telescopic slide rods pass through the outer side and inside the spring support plate and are slidably connected to the spring support plate.

[0010] Preferably, a support spring is provided between the connecting plate and the spring support plate, and the support spring is located between multiple telescopic slide rods, and multiple fan blades are connected to the lower side of the connecting shaft.

[0011] Preferably, a limiting ring is connected at the middle of the outer side of the connecting shaft, and the limiting ring is located on the lower side between the multiple fan blades and the limiting frame, and a rotating groove is opened at the center of the upper end of the inner support rod.

[0012] Preferably, a rotating head is rotatably connected inside the rotating groove, and the rotating head is connected to the center of the lower end of the spring support plate. Multiple balls are rotatably connected to the inner side of the lower end of the rotating head, and the multiple balls are attached to the inner wall of the rotating groove.

[0013] Beneficial effects:

[0014] 1. This utility model uses multiple rotationally symmetrical humanoid bionic wind blades to rotate under wind power, simulating human activity patterns, and combines them with an up-and-down floating mechanism to enhance the dynamic realism, achieving the dual effects of visual deterrence and physical dispersal.

[0015] 2. When the fan blades of this utility model are driven to rotate by wind, a reverse airflow is generated inside the wind duct to push the connecting shaft to move up and down. In conjunction with the support spring, an adaptive floating is formed, which utilizes natural wind energy to achieve dynamic adjustment without power, thereby improving the randomness and realism of the bird-repelling action.

[0016] 3. The buzzer of this utility model plays the sounds of birds' natural enemies through an electrical box, which, together with the visual deterrence of the bionic wind blades, forms a sound and light linkage to enhance the bird-repelling effect. At the same time, the photovoltaic power supply system ensures continuous operation and achieves self-sufficiency in electricity.

[0017] 4. This utility model uses the sliding cooperation between the connecting plate, the telescopic slide rod and the spring support plate to make the support spring rotate synchronously with the rotating shaft, avoiding damage to the spring due to torsional force. At the same time, the limit ring and the rotating groove-rotating head structure ensure the lifting stability and component life.

[0018] 5. The photovoltaic panel of this utility model converts light energy into electrical energy and stores it in a storage battery. The inverter then powers the buzzer, achieving energy self-sufficiency without the need for an external power source. This makes it suitable for long-term deployment in the field and reduces maintenance costs. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] To achieve the above-mentioned utility model objectives, such as Figures 1-4As shown, this utility model provides a biomimetic sound-based bird deterrent device, including a mounting base 1. An outer support rod 2 is connected to the center of the upper end of the mounting base 1. A fan duct 3 is connected to the upper end of the outer support rod 2. A connecting shaft 4 is inserted into the upper end of the fan duct 3. Multiple connecting horizontal rods 5 are connected to the upper end of the connecting shaft 4. Connecting vertical rods 6 are connected to the outer sides of the upper ends of the multiple connecting horizontal rods 5. Vertically upward-pointing biomimetic fan blades 7 are connected to the upper ends of the multiple connecting vertical rods 6. The multiple biomimetic fan blades 7 are all human-shaped and arranged rotationally symmetrically around the central axis of the connecting shaft 4. Photovoltaic panels 8 are arranged on the inner sides between the multiple connecting horizontal rods 5. An electrical box 9 is located at the upper end of the connecting shaft 4. A buzzer 10 is located at the upper end of the electrical box 9. The electrical box 9 is electrically connected to the multiple photovoltaic panels 8 and the buzzer 10 via a wiring harness. The bird deterrent device is fixed at the bottom by the mounting base 1 and is activated by the external... Support rod 2 provides support at the bottom. In addition, the bird repeller simulates human movement by rotating multiple humanoid bionic fan blades 7 and emits sounds of bird predators through a buzzer 10 to scare birds, thereby achieving the purpose of bird repeller. The multiple bionic fan blades 7 can also move up and down while rotating to increase the realism of the simulation and enhance the bird repeller effect. During this process, the buzzer 10 is powered by an electrical box 9 and the sound emitted is controlled by the electrical box 9. The electrical box 9 contains a storage battery, a charging controller, an inverter, and a sound controller. Multiple photovoltaic panels 8 convert light energy into electrical energy and store the electrical energy in the storage battery inside the electrical box 9 through the charging controller. The storage battery powers the buzzer 10 through the inverter. Photovoltaic power generation, energy storage, and power supply are existing known technologies and will not be described in detail again.

[0028] Preferably, the upper end of the outer support rod 2 is connected to a limiting frame 11, and the connecting shaft 4 passes through the center of the limiting frame 11 and is slidably connected to the limiting frame 11. The lower end of the connecting shaft 4 is connected to a connecting plate 12, and multiple telescopic slide rods 13 are connected to the outer side of the lower end of the connecting plate 12. The center of the inner wall of the lower end of the connecting shaft 4 is connected to an inner support rod 14, and the upper end of the inner support rod 14 is rotatably connected to a spring support plate 15. The multiple telescopic slide rods 13 pass through the inner side of the spring support plate 15 and are slidably connected to the spring support plate 15. A support spring 16 is provided between the connecting plate 12 and the spring support plate 15, and the support spring 16 is located between the multiple telescopic slide rods 13. Multiple fan blades 17 are connected to the lower side of the outer side of the connecting shaft 4, and a limiting ring 18 is connected to the middle of the outer side of the connecting shaft 4. The limiting ring 18 is located slightly lower between the multiple fan blades 17 and the limiting frame 11. During the use of the bird deterrent device, since multiple bionic fan blades 7 are arranged in a rotationally symmetrical manner around the center of gravity axis of the connecting shaft 4, when there is wind outside, the multiple bionic fan blades 7 will rotate around the center of gravity axis of the connecting shaft 4 under the blowing force of the wind, and drive multiple fan blades 17 to rotate inside the wind tube 3. The rotation of multiple fan blades 17 generates wind blowing into the wind tube 3, causing multiple fan blades 17 to move upward under the reaction force of the internal wind. The multiple fan blades 17 drive multiple bionic fan blades 7 to move upward through the connecting shaft 4, connecting horizontal bar 5 and connecting vertical bar 6. Since the strength of the external wind is variable, the internal wind generated by multiple fan blades 17 fluctuates, causing multiple fan blades 17 to move up and down under the elastic support of the supporting spring 16, causing multiple bionic fan blades 7 to float randomly up and down, thereby producing a realistic simulation effect and improving the bird deterrent effect.

[0029] The vertical movement of multiple fan blades 17 can be limited by the limiting ring 18 to prevent the uppermost fan blade 17 from colliding with the limiting frame 11 and causing damage. In addition, the connecting shaft 4 can drive the spring support plate 15 to rotate together through the connecting plate 12 and multiple telescopic slide rods 13, so that the support spring 16 located between the connecting plate 12 and the spring support plate 15 can rotate with the connecting shaft 4, avoiding damage to the support spring 16 due to torsional force. Under the action of the support spring 16, the spring support plate 15 is always located at the upper end of the inner support rod 14 and will not separate from the inner support rod 14, nor will it move up and down with the connecting shaft 4. Furthermore, the connecting shaft 4 can move up and down smoothly through the sliding of multiple telescopic slide rods 13 inside the spring support plate 15.

[0030] Preferably, a rotating groove 19 is provided at the center of the upper end of the inner support rod 14. A rotating head 20 is rotatably connected inside the rotating groove 19, and the rotating head 20 is connected to the center of the lower end of the spring support plate 15. Multiple balls 21 are rotatably connected inside the outer side of the lower end of the rotating head 20, and the multiple balls 21 are attached to the inner wall of the rotating groove 19. During the rotation of the spring support plate 15, the spring support plate 15 can be connected and limited with the inner support rod 14 through the rotating groove 19 and the rotating head 20, and the multiple balls 21 can reduce the rotational resistance between the spring support plate 15 and the inner support rod 14, so that the rotation of the spring support plate 15 is smoother.

[0031] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
