Description

Technical Field

[0001] The utility model relates to the technical field of bird-repelling devices, in particular to an automatic loading structure for bird-repelling devices. Background Art

[0002] In the aerospace industry, bird repelling during takeoff and landing is a crucial safety measure. Hundreds of bird-aircraft collisions occur worldwide each year, potentially causing engine damage, windshield ruptures, and even serious threats to the lives of passengers and crew. Therefore, minimizing bird interference with aircraft operations is crucial. To address this challenge, airports employ a variety of bird repellent methods, including ultrasound and digital voice commands. However, birds gradually adapt to these sounds. Currently, a common and effective method involves using bird repellent devices equipped with bird repellent munitions, which use the sound waves, shock waves, and bright lights generated by the explosion to repel birds. However, this method has significant drawbacks: airports experience a large number of flights daily, and bird repellent devices can only be loaded with one round at a time, requiring frequent ammunition changes, resulting in low efficiency. Furthermore, the device requires a large number of operators, making the work tedious and demanding.

[0003] Therefore, there is an urgent need to develop a highly automated and efficient loading structure to realize automatic bullet replacement of bird repellent devices, so as to effectively combat the bird threat around airports, ensure aviation safety, protect facilities and assets, maintain ecological balance, and provide reliable guarantees for the sustainable development of the aviation industry. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide an automatic loading structure for a bird-repelling device.

[0005] The purpose of the utility model is achieved through the following technical solutions: an automatic loading structure for a bird-repelling device, comprising a magazine, a stepping motor, a reducer, a coupling, a connecting frame, a guide, a turntable, a circular encoding disk, a fixing frame and a rotating shaft; the input end of the reducer is connected to the stepping motor, the output end is fixedly connected to the fixing frame, and then the fixing frame is fixedly connected to the back of the magazine; the circular encoding disk is mounted on the rotating shaft; the turntable is located at the bottom of the magazine, connected to one end of the coupling through the rotating shaft, and the other end of the coupling is connected to the output shaft of the output end of the reducer.

[0006] Preferably, the turntable is provided with six evenly distributed notches, and the size of each notch matches the ammunition.

[0007] Preferably, the circular encoding disk is provided with six evenly distributed slits, and the positions of the six slits coincide with the centers of six evenly distributed slots on the turntable. The optical signal of the slot-shaped optical fiber sensor can pass through the six slits, thereby determining the position of the turntable slot.

[0008] Preferably, the stepper motor rotates in one direction, causing the ammunition wrapped on the turntable to fall in one direction, and is combined with a reducer with a reduction ratio of 10 to increase the torque.

[0009] Preferably, a slot-type fiber optic sensor and a fiber optic sensor are also installed on the back of the magazine. The slot-type fiber optic sensor is installed in a vertical position. When the photoelectric signal passes through one of the slits of the circular encoding disk, the vertical position of the slot of the turntable is consistent with the circular encoding disk, ensuring that the bullet in the slot can fall smoothly; the position of the fiber optic sensor corresponds to a slot of the turntable, which is used to detect whether there is a traceless bullet in the slot.

[0010] Preferably, the slot-shaped optical fiber sensor is used to detect whether the turntable has returned to zero point through a circular encoding disk; and the optical fiber sensor is used to detect whether there is ammunition in the turntable.

[0011] Preferably, a second fiber optic sensor is installed on the right side of the magazine; when the ammunition in the magazine is reduced to the position of the second fiber optic sensor, the second fiber optic sensor senses the lack of ammunition and sends out a lack of ammunition signal. After the control system detects the lack of ammunition signal, it automatically sends an alarm signal to remind the staff to change the material.

[0012] Preferably, the guide is connected to the magazine via a connecting frame.

[0013] Preferably, the upper portion of the guide is a square opening, and the lower portion is a round opening.

[0014] Preferably, an adjusting pin is installed inside the guide to change the direction of the ammunition when the ammunition falls smoothly into the guide, ensuring that the fuse of the traceless bullet is facing downward.

[0015] The beneficial effects of the utility model are:

[0016] 1) Compared with traditional manual ammunition replacement, the automatic loading structure of the utility model can complete ammunition replacement in a short time, significantly improving the efficiency of the bird-repelling device and reducing human errors in operation; at the same time, its ammunition storage design can store a large amount of ammunition, increasing the durability of the structure and reducing the frequency of ammunition replenishment;

[0017] 2) The utility model is equipped with optical fiber sensors, optical fiber sensors and slot-type optical fiber sensors in the structure, which realize the device's material shortage detection, material leakage detection and the rotation position detection of the turntable magazine, ensuring that the ammunition is reliably loaded into the bird-repelling device;

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. It should be understood that the following drawings only show certain embodiments of the present invention and should not be regarded as limiting the scope. For ordinary technicians in this field, other relevant drawings can be obtained based on these drawings without making any creative work. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection of the present invention.

[0024] The utility model is suitable for places where bird repelling measures are required, and is particularly suitable for airport scenes and aviation ports with dense air traffic and rich surrounding ecological environment.

[0025] This utility model patent can provide a more intelligent and efficient airport bird-repelling solution, while promoting the safety and sustainable development of the aviation industry.

[0026] In this embodiment, the utility model provides an automatic loading structure for a bird-repelling device, such as Figure 1 and Figure 2 As shown, it includes a magazine 1, a stepper motor 2, a reducer 3, a coupling 4, a slotted optical fiber sensor 5, an optical fiber sensor 6, a connecting frame 7, an adjusting pin 8, a guide 9, a turntable 10, a second optical fiber sensor 11, a circular encoding disk 12, a fixing frame 13, ammunition 14, and a rotating shaft 15.

[0027] Furthermore, the input end of the reducer 3 is connected to the stepper motor 2, and the output end is fixedly connected to the fixing bracket 13, and then the fixing bracket 13 is connected to the back of the magazine 1; the turntable 10 is located at the bottom of the magazine 1, and is connected to one end of the coupling 4 through the rotating shaft 15, and the other end of the coupling 4 is connected to the output shaft of the output end of the reducer 3; the circular encoding disk 12 is installed on the rotating shaft 15, and is located between the coupling 4 and the back of the magazine 1; the slot-type optical fiber sensor 5 is installed on the back of the magazine 1, and its vertical position is consistent with the circular encoding disk 12; the optical fiber sensor 6 is installed on the back of the magazine 1, corresponding to a slot of the turntable 10; the second optical fiber sensor 11 is installed on the right side of the magazine 1; the upper part of the guide 9 is a square opening and the lower part is a round opening, and is connected to the magazine 1 through the connecting frame 7.

[0028] Furthermore, the magazine 1 can be opened and closed by a magnetic handle to replace ammunition, which is convenient and quick, and has the effect of being waterproof and sun-proof. In addition, the magazine as a whole has a certain inclination, which can stabilize the ammunition and prevent the magazine from shaking or the ammunition from accidentally falling.

[0029] Further, such as Figure 3 As shown, the stepper motor 2 rotates in one direction, causing the ammunition 14 wrapped in the turntable 10 to fall in one direction to prevent the ammunition from falling off, and at the same time cooperates with the reducer 3 with a reduction ratio of 10 to increase the torque.

[0030] Furthermore, the turntable 10 is provided with six evenly distributed slots, the size of each slot being perfectly matched with the ammunition, and the six slots can take turns wrapping the ammunition for loading, thereby greatly improving the loading efficiency.

[0031] Furthermore, the second optical fiber sensor 11 is installed on the right side of the magazine 1. When the ammunition in the magazine 1 is reduced to the position of the second optical fiber sensor 11, it means that the ammunition in the magazine is about to be exhausted. The second optical fiber sensor issues an alarm to remind the staff to change the material.

[0032] Furthermore, the optical fiber sensor 6 is used to detect whether there is ammunition in the turntable 10, and if there is no ammunition, an ammunition leakage alarm will be issued.

[0033] Furthermore, the slot-type optical fiber sensor 5 detects whether the turntable 10 has returned to zero through the circular encoder disk. If not, the information is fed back to the main control board, and then fine-tuned through the stepper motor 2.

[0034] Furthermore, the upper part of the guide 9 is square and the lower part is round. At the same time, an adjusting pin 8 perpendicular to the ammunition placement direction is installed inside, which can make the ammunition fall smoothly into the guide 9 and change the direction of the ammunition so that the ammunition falls vertically into the bird-repelling device. When the ammunition falls, one end touches the adjusting pin, so that the direction of the end of the traceless bullet that touches the adjusting pin changes from horizontal to upward, and the fuse end faces downward, and the ammunition changes from horizontal to vertical and enters the bird-repelling barrel, completing the bullet changing task.

[0035] When loading the bird-repellent device based on the automatic loading structure of the utility model, the operator first fills the magazine 1 with ammunition 14. The stepper motor 2 starts to rotate, increasing the output torque through the speed reducer 3, driving the rotating shaft 15 connected to the coupling 4 to rotate unidirectionally, while also driving the rotating disk 10 on the rotating shaft. The zero point state of the rotating disk is detected by the slot-shaped optical fiber sensor 5 through the circular code disk 12. If it is not in the zero point state, an alarm is triggered to adjust the stepper motor 2 to adjust its state. Then, the ammunition 14 enters the notch of the rotating disk 10, wrapped by the rotating disk and rotated with the rotating disk. The optical fiber sensor 6 monitors the ammunition state in the notch in real time and issues an alarm if any leakage is detected. When the notch opens downward, the ammunition 14 falls off from the notch and falls horizontally into the guide 9. One end of the ammunition touches the adjusting pin 8, causing it to change from horizontal to vertical and enter the lower part of the guide and continue to fall downward along the circular opening until it falls into the bird-repellent device, completing the loading of the bird-repellent device. When the ammunition in the magazine reaches the position of the second fiber optic sensor 11, it detects the shortage and triggers an alarm, prompting the operator to restock. This reloading process is achieved through an automated stepper motor and sensor system, ensuring the stability and continuity of the bird repellent device during operation.

It should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments.
