Abstract
Description
Technical Field
[0001] This utility model relates to the field of automatic bird deterrent devices, and in particular to an automatic bird deterrent device for a high-mast lamp. Background Technology
[0002] With the development of civil aviation, the threat of bird strikes to flight safety has received high attention. Bird strikes can cause aircraft damage, component failure, and even crashes resulting in loss of life and safety. Airports have incorporated bird control into their key safety management practices. High-mast lights on the apron, as crucial lighting equipment in the flight area, frequently see bird nests, affecting illumination. Large nests can block the light from the high-mast lights, interfering with pilots' judgment of the runway and taxiway, especially at night or in low visibility conditions, which is extremely detrimental to aircraft takeoff and landing guidance. This threatens flight safety. Furthermore, birds active near high-mast lights increase the risk of bird strikes during takeoff and landing. When birds are startled and fly away from their nests, their flight direction is unpredictable, further increasing the risk of bird strikes.
[0003] Therefore, it is necessary to propose an automatic bird deterrent device for high-mast lights to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide an automatic bird deterrent device for high mast lights, in order to solve the problem that birds nesting on high mast lights can easily lead to bird strikes during aircraft take-off and landing.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic bird deterrent device on a high-mast light, comprising a pole, a frame, an LED light, and a bird deterrent mechanism, wherein the frame is installed on the upper end of the pole, and the LED light is installed on the frame;
[0006] The bird deterrence mechanism is located above the frame. The bird deterrence mechanism includes a bird deterrence box, a windmill, a lens, and an electrical box. The electrical box is located inside the bird deterrence box. The windmill is rotatably located above the bird deterrence box. The upper end of the bird deterrence box is equipped with a device for converting wind power into electrical energy. The lens is fixedly located on both sides of the blades at the upper end of the windmill.
[0007] The electrical box is equipped with an infrared sensor, a time relay, an intermediate relay, and a bird-repelling speaker.
[0008] When the infrared sensor detects birds approaching or perching on the frame, the infrared photoelectric sensor switch generates an output signal. This signal, combined with a time relay and an intermediate relay, controls the bird deterrent speaker to emit the sound of eagles. The time relay outputs seconds. After the birds fly away, the bird deterrent speaker stops emitting sound, and the infrared sensor resets to the warning working state.
[0009] Preferably, the frame is provided with a slot that extends through both the upper and lower ends of the frame, and a base is slidably disposed in the slot, with the bottom of the bird deterrent box fixed to the upper surface of the base.
[0010] Preferably, a first retaining ring and a second retaining ring are fixedly provided on the upper surface of the base and the upper surface of the frame, respectively. An electric push rod is fixedly installed on one side of the bird deterrent box. A retaining rod is fixedly connected to the telescopic end of the electric push rod. The electric push rod is set horizontally, and the retaining rod cooperates with the first retaining ring and the second retaining ring.
[0011] Preferably, a power box is installed below the rod, and a winding mechanism is provided in the power box. A wire rope on the winding mechanism extends out of the power box, and one end of the wire rope extending out of the power box is fixedly connected to the clamp rod.
[0012] Preferably, the middle part of the frame is supported on the rod by a sliding wheel.
[0013] Preferably, a lithium battery is installed on the frame. When the windmill rotates, the device that converts wind power into electrical energy converts wind power into electrical energy, which is stored in the lithium battery. The lithium battery is used to provide power to the bird deterrent speaker.
[0014] The technical effects and advantages of this utility model are as follows:
[0015] 1. This utility model utilizes an infrared photoelectric sensor switch to automatically drive away birds, greatly reducing the input of manpower and material resources. It drives away birds with an extremely fast response speed, preventing them from stopping and nesting, preventing the weakening of lighting effects caused by nesting, reducing the number of birds near the airport, and lowering the risk of bird strikes.
[0016] 2. When the electric push rod pushes the locking rod to engage with the first locking ring, the winding mechanism can use the wire rope to release the base and bird deterrent mechanism to descend independently, which is convenient for maintenance, without having to lower the entire heavy frame, thus saving energy.
[0017] 3. This utility model simultaneously achieves the purpose of converting wind energy into electrical energy and repelling birds. Attached Figure Description

[0021] This utility model provides, for example Figure 1 and Figure 2 An automatic bird deterrent device for a high-mast light is shown, comprising a pole 1, a frame 2, an LED light 3, and a bird deterrent mechanism 4. The frame 2 is installed on the upper end of the pole 1, and the LED light 3 is installed on the frame 2.
[0022] The bird deterrence mechanism 4 is located above the frame 2. The bird deterrence mechanism 4 includes a bird deterrence box 8, a windmill 6, a lens 7, and an electrical box 9. The electrical box 9 is located inside the bird deterrence box 8. The windmill 6 is rotatably located above the bird deterrence box 8. The upper end of the bird deterrence box 8 is equipped with a device for converting wind power into electrical energy. The lens 7 is fixedly located on both sides of the blades at the upper end of the windmill 6.
[0023] Electrical box 9 is equipped with an infrared sensor, a time relay, an intermediate relay, and a bird-repelling speaker;
[0024] When the infrared sensor detects birds approaching or perching on frame 2, the infrared photoelectric sensor switch generates an output signal. Combined with the time relay and intermediate relay, this signals the bird deterrent speaker to emit the sound of eagles. The time relay outputs a 15-second signal. After the birds fly away, the bird deterrent speaker stops emitting sound, and the infrared sensor resets to the warning working state.
[0025] This invention utilizes an infrared photoelectric sensor switch to automatically drive away birds, greatly reducing the investment of manpower and resources. It drives away birds with an extremely fast response speed, preventing them from stopping and nesting, reducing the effect of lighting due to nesting, and reducing the number of birds near the airport, thereby lowering the risk of bird strikes.
[0026] A slot 11 is provided on the frame 2, which passes through both the upper and lower ends of the frame 2. A base 10 is slidably disposed in the slot 11, and the bottom of the bird deterrent box 8 is fixed to the upper surface of the base 10. A first retaining ring 12 and a second retaining ring 13 are fixedly disposed on the upper surface of the base 10 and the upper surface of the frame 2, respectively. An electric push rod 16 is fixedly installed on one side of the bird deterrent box 8. A retaining rod 14 is fixedly connected to the telescopic end of the electric push rod 16. The electric push rod 16 is horizontally disposed, and the retaining rod 14 cooperates with the first retaining ring 12 and the second retaining ring 13. A power box 5 is installed below the rod body 1. A winding mechanism is provided in the power box 5. A steel wire rope 15 on the winding mechanism extends out of the power box 5, and one end of the steel wire rope 15 extending out of the power box 5 is fixedly connected to the retaining rod 14.
[0027] During operation, when the electric push rod 16 pushes the locking rod 14 to engage with the first locking ring 12, the winding mechanism can use the wire rope 15 to loosen the base 10 and the bird deterrent mechanism 4 to descend independently, which is convenient for maintenance, without having to lower the entire heavier frame 2, thus saving energy.
[0028] When the electric push rod 16 pushes the locking rod 14 to simultaneously engage with the first locking ring 12 and the second locking ring 13, the winding mechanism can use the wire rope 15 to loosen the frame 2 and lower it, which facilitates overall maintenance and makes it easy to use according to actual needs.
[0029] It should be noted that the winding mechanism refers to conventional electric hoists, winches, wire rope winding equipment, etc., and is not limited here.
[0030] In another embodiment, the winding mechanism is located at the bottom of the rod 1.
[0031] It should also be noted that the middle part of frame 2 is supported on rod 1 by three sliding wheels, which allows frame 2 to move vertically up and down.
[0032] A lithium battery 17 is installed on the frame 2. When the windmill 6 rotates, the device that converts wind power into electrical energy converts wind power into electrical energy, which is stored in the lithium battery 17. The lithium battery 17 is used to provide power to the bird-repelling speaker. It saves energy, and the effect of the mirror 7 reflecting light during the rotation of the windmill 6 also achieves a bird-repelling effect. In other words, it simultaneously achieves the purpose of converting wind energy into electrical energy and repelling birds.
[0033] It should be noted that converting wind power into electricity is a common existing technology, and the specific components used will not be described in detail here.
