Description

Technical Field

[0001] This invention relates to the field of airport bird control technology, and in particular to a bird-catching net with an alarm function. Background Technology

[0002] Bird collisions with aircraft are a long-standing problem in airport operations. Due to the speed and size of aircraft, even small birds can cause serious damage. To reduce this risk, airports typically employ various measures to deter birds. Among these, bird trapping is an auxiliary bird control measure during flight. Airport birdwatchers, through long-term observation, identify the main activity ranges of common birds at the airport and key areas for aircraft takeoff and landing. Bird traps and nets are then deployed in these areas to capture birds and reduce their numbers.

[0003] In existing bird-catching nets, birds often become trapped when they collide with the net, unable to escape. This can lead to injury or even death as the birds struggle within the net, violating the principles of wildlife protection. To address this issue, some airports deploy staff for frequent patrols to check for trapped birds, which incurs high labor costs. Furthermore, existing bird-catching nets often leave birds hanging upside down after impact, causing significant harm. Summary of the Invention

[0004] The purpose of this invention is to provide a bird-catching net with an alarm function, which can promptly alert staff to rescue the bird, prevent the bird from being injured, and prevent the bird from getting upside down on the net after hitting it, thus reducing harm to the bird.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0006] A bird-catching net with an alarm function includes multiple support posts arranged side by side. Each support post has a T-shaped groove on its opposite side, which is wider at the inside and narrower at the outside. Each support post also has a limiting groove on its opposite side, which is located at the edge of the T-shaped groove. Multiple inclined hanging net rods are slidably connected to the opposite side of each support post. Each inclined hanging net rod is provided with a T-shaped sliding shaft slidably connected to the T-shaped groove and a limiting sliding shaft slidably connected to the limiting groove. A bird-catching net is set between two adjacent support posts. The edges of each bird-catching net are connected to the corresponding inclined hanging net rods. Each bird-catching net unfolds into a wave shape.

[0007] Each support column is provided with a winding housing at its upper end. Each winding housing has a threading hole at its lower end that communicates with the corresponding T-shaped slide groove. Each winding housing is rotatably connected to a winding wheel. Each winding housing is equipped with a drive motor for driving the winding wheel to rotate. Each winding wheel is wound with a pull rope. The free end of each pull rope passes through the corresponding threading hole and is connected to each T-shaped slide shaft in the corresponding T-shaped slide groove. The free end of each pull rope is connected to the lower end of the corresponding T-shaped slide groove.

[0008] Each cable reel housing has a mounting bracket at its upper end, and each mounting bracket is equipped with a monitoring camera tilted towards the corresponding bird-catching net. It also includes a cable passing through each cable reel housing. Each drive motor and each monitoring camera are electrically connected to the cable, and the cable is connected to the control center.

[0009] By adopting the above technical solution, when a bird hits the net, the monitoring camera transmits the image back to the control center. The intelligent algorithm automatically determines that a bird has hit the net, and the system notifies staff to go to the designated bird-catching net to check. When the staff arrives and finds a bird hitting the net, they control the drive motors on both sides to reverse, driving the reel to rotate. The pull rope is gradually released from the reel, and under the weight, the inclined hanging pole gradually slides down and eventually stacks together. At this time, the staff can remove the bird from the bird-catching net. Then, the drive motors on both sides are controlled to rotate forward again, driving the reel to rotate forward. The rotation of the reel gradually winds the pull rope around it, eventually straightening the pull rope in the T-shaped groove, pulling the inclined hanging pole to unfold the bird-catching net into a wave shape again.

[0010] A further feature of the present invention is that: each winding housing is rotatably connected to a drive shaft arranged in the same direction as the corresponding winding wheel; one end of each winding wheel is provided with a drive gear; one end of each drive shaft is provided with a transmission gear meshing with the corresponding drive gear; a spiral circulation groove is formed on the outer side of each drive shaft, the spiral circulation groove being formed by two spiral grooves with opposite spiral directions connected end to end; a slide rail is provided in each winding housing near the corresponding drive shaft; each slide rail is provided with a strip-shaped slide groove arranged along the length direction of the drive shaft; a slider is slidably connected to each strip-shaped slide groove; a slide shaft is provided on the side of each slider near the corresponding drive shaft and slidably connected to the corresponding spiral circulation groove; a lead arm is provided on the side of each slider away from the corresponding drive shaft towards the corresponding winding wheel; each lead arm is provided with a threading collar; and each pull rope passes through the winding wheel, through the threading collar, and then through the threading hole.

[0011] By adopting the above technical solution, while the drive motor drives the winding wheel to rotate, the winding wheel drives the drive shaft to rotate. Due to the connection between the sliding shaft and the spiral circulation groove, the drive shaft drives the lead arm to slide back and forth along the slide rail, pulling the pull rope back and forth, and evenly winding it on the winding wheel.

[0012] A further feature of the present invention is that both the winding reel and the drive shaft are arranged vertically.

[0013] A further feature of the present invention is that the length of the pull rope between any two adjacent T-shaped sliding shafts is equal.

[0014] A further feature of the present invention is that each inclined hanging pole is provided with a hanging shaft at both ends.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] Firstly, the bird-catching net of the present invention is equipped with a real-time monitoring camera that transmits the monitoring images back to the control center in real time. It also uses intelligent algorithms to automatically determine whether a bird has collided with the net. Once a bird is detected, the net will promptly notify staff to check it. This eliminates the need for staff to patrol regularly, thus reducing labor costs.

[0017] Secondly, the bird-catching net of the present invention is wavy when unfolded. After a bird hits the net, its feet are more likely to come into contact with the upward side of the net and get caught on it. This makes the bird caught on the inclined surface, making it less likely for the bird to hang upside down on the net, thus reducing the damage to the bird during bird catching.

[0018] Thirdly, this invention allows for free control of the bird-catching net's downward folding and upward unfolding, making it easy to remove birds from the net;

[0019] Fourth, the present invention drives the lead arm to slide back and forth along the slide rail via the drive shaft. During the winding process of the winding wheel, the pull rope can move back and forth along both ends of the winding wheel, so that it can be evenly wound on the winding wheel.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] In the description of this invention, it should be understood that the terms "upper", "lower", "left", "right", "front", "rear", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0028] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0029] Example, refer to Figure 1-5 A bird-catching net with an alarm function includes multiple support posts 1 arranged side by side. Each support post 1 has a T-shaped groove 11 on its opposite side, which is larger inside and smaller outside. Each support post 1 also has two limiting grooves 12 on its opposite side, which are located at the edge of the T-shaped groove 11 and are arranged along its height. Each support post 1 has multiple inclined hanging net rods 2 slidably connected to its opposite side. Each inclined hanging net rod 2 is provided with a T-shaped sliding shaft 21 that is slidably connected to the T-shaped groove 11 and a limiting sliding shaft 22 that is slidably connected to the two limiting grooves 12. Each inclined hanging net pole 2 has a hanging net shaft 23 at both ends. A bird-catching net 3 is set between two adjacent support columns 1. The edges of each bird-catching net 3 are connected to the corresponding limiting sliding shaft 22. Each bird-catching net 3 unfolds in a wave shape. After the bird-catching net 3 unfolds in a wave shape, the bird's feet are more likely to come into contact with the upward side of the bird-catching net 3 and get caught on the net. This makes it easier for the bird to be caught on the inclined surface and prevents the bird from getting upside down on the net, thus reducing the damage to the bird when catching it.

[0030] Each support column 1 has a winding housing 4 at its upper end. Each winding housing 4 has a threading hole 41 at its lower end that communicates with the corresponding T-shaped groove 11. Each winding housing 4 has a vertically arranged winding wheel 5 rotatably connected inside. Each winding housing 4 has a drive motor 51 installed inside to drive the winding wheel 5 to rotate. The drive motor 51 is vertically installed at the upper end of the winding wheel 5. Each winding wheel 5 has a pull rope 6 wound on it. The free end of each pull rope 6 passes through the corresponding threading hole 41 and is connected to each T-shaped sliding shaft 21 in the corresponding T-shaped groove 11. The free end of each pull rope 6 is connected to the lower end of the corresponding T-shaped groove 11. The length of the pull rope 6 between every two adjacent T-shaped sliding shafts 21 is equal.

[0031] Each winding housing 4 is rotatably connected to a vertically arranged drive shaft 7. Each winding reel 5 has a drive gear 52 at one end. Each drive shaft 7 has a transmission gear 71 at one end that meshes with the corresponding drive gear 52. Each drive shaft 7 has a spiral circulation groove 72 on its outer side. The spiral circulation groove 72 is formed by connecting two spiral grooves with opposite spiral directions end to end. The two spiral grooves intersect to form a sliding groove that can circulate at both ends of the drive shaft 7. Each winding housing 4 has a vertically arranged slide rail 8 near the corresponding drive shaft 7. Each slide rail 8 has a strip groove 81 arranged along the length of the drive shaft 7. Each strip groove 81 is slidably connected to a slider 82. Each slider 82 has a slide shaft 83 slidably connected to the corresponding spiral circulation groove 72 on the side near the corresponding drive shaft 7. Each slider 82 has a wire pulling arm 84 arranged on the side away from the corresponding drive shaft 7 towards the corresponding winding wheel 5. Each wire pulling arm 84 is provided with a wire threading collar 85. Each pull rope 6 passes through the wire threading collar 85 from the winding wheel 5 and then passes into the wire threading hole 41.

[0032] Each cable housing 4 has a mounting bracket 42 at its upper end. Each mounting bracket 42 has a monitoring camera 9 tilted towards the corresponding bird net 3. The monitoring camera 9 is used to monitor the bird net 3 in real time. After the image is transmitted back to the control center, an intelligent algorithm is used to automatically determine whether a bird has hit the net. It also includes a cable 10 that passes through each cable housing 4. Each drive motor 51 and each monitoring camera 9 are electrically connected to the cable 10. The cable 10 is connected to the control center.

[0033] Working principle: When a bird hits the net, the monitoring camera 9 transmits the image back to the control center. Using an intelligent algorithm, the system automatically determines that a bird has hit the net and notifies staff to check the designated bird-catching net. Upon arrival and finding the bird, staff control the drive motors 51 on both sides to reverse, causing the reel 5 and drive shaft 7 to rotate. During the rotation of drive shaft 7, due to the connection between the sliding shaft 83 and the spiral circulation groove 72, drive shaft 7 drives the lead arm 84 to slide back and forth along the slide rail 8, and the pull rope 6 is gradually released from the reel 5. Under the action, the inclined hanging net pole 2 gradually slides downward and eventually stacks together, at which point the workers can remove the birds from the bird-catching net 3; then the drive motors 51 on both sides are controlled to rotate forward again, driving the winding wheel 5 and drive shaft 7 to rotate forward. The winding wheel 5 rotates and gradually winds the pull rope 6 around it. The drive shaft 7 drives the pulling arm 84 to slide back and forth along the slide rail 8, pulling the pull rope 6 back and forth, evenly winding it around the winding wheel 5, and finally straightening the pull rope 6 in the T-shaped slide groove 11, pulling the inclined hanging net pole 2 to unfold the bird-catching net 3 into a wave shape again.
