Description

Technical Field

[0001] This utility model belongs to the technical field of bird-catching equipment, specifically relating to a bird-catching cage. Background Technology

[0002] During takeoff and landing, aircraft fly at low altitudes, making them susceptible to collisions with birds near airports. Bird strikes often result in severe damage to the aircraft and can even lead to accidents. Therefore, it is necessary to deploy bird-catching devices near airports—non-lethal tools—to control bird populations and reduce flight safety risks. These devices aim to reduce the presence of dangerous birds at airports and facilitate the rescue of accidentally captured protected animals. However, existing bird-catching devices used at airports are mostly complex in design, often disposable, and inefficient, increasing the workload for staff and limiting their practicality.

[0003] In view of this, and in order to solve the above-mentioned technical problems, this utility model proposes a bird trap with a simple structure, high practicality, and the ability to induce birds to enter the trap on their own, resulting in high capture efficiency. This design can effectively control the number of birds at airports, reduce flight safety risks, and will not cause harm to birds or cause adverse effects such as environmental pollution.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] See Figure 1-6 A bird trap includes a cage body 1 with an open top and a perimeter designed to restrict bird movement. The cage body 1 consists of a frame made of multiple vertical and horizontal bars, with a mesh structure woven from wire or other woven materials inside the frame. Cage doors are located on the four sides of the cage body 1, with the doors situated in the lower center. Each cage door has an opening / closing mechanism 2 that allows birds to enter and closes automatically. Support rods 3 are vertically mounted on opposite sides of the top surface of the cage body 1, and a rotating rod 4 is rotatably connected between the two support rods 3. Frames 5 are inclined downwards on both sides of the rotating rod 4, with the lower ends of both frames 5 facing inwards towards the cage body 1. Each frame 5 contains a net 6 designed to prevent birds from escaping, and each net 6 has a food placer 7. Bird food can be placed in the food placer 7 to entice birds to eat and fall into the cage body 1.

[0024] The two frames 5 are preferably provided with standing poles 8 for birds to stand on at the bottom. The food placement piece 7 is set on the netting 6 diagonally above the standing poles 8. The design of the standing poles 8 makes it easy for birds to stand on the standing poles 8 when they fly over to feed. Then, the birds' own weight causes the frame 5 to tilt to the other side, so that the birds fall into the cage 1.

[0025] The two support rods 3 are preferably provided with bearing mounting parts at their tops, and ball bearings 9 are fixedly mounted on the two bearing mounting parts. The two ends of the rotating rod 4 are respectively connected to the ball bearings 9. The ball bearings 9 are designed to reduce the friction when the rotating rod 4 rotates, so that the bird loses its balance and enters the cage 1 instantly.

[0026] The preferred cage body 1 has two downwardly inclined sliding plates 10 symmetrically arranged on both sides of the upper end, with the bottom of the sliding plates 10 facing the inside of the cage body 1. The lower ends of the two sliding plates 10 are respectively arranged with gaps between them and the lower ends of the two frames 5. The sliding plates 10 on both sides are arranged to reduce the friction of the bird when it loses its balance and falls into the cage body 1, so that it can enter the cage body 1 more quickly.

[0027] Preferably, the upper ends of the two sliding plates 10 are horizontally connected to the insert plates 11, and slots for inserting the insert plates 11 are opened on both sides of the upper end of the cage body 1. The two insert plates 11 are fixed by bolts set on the top of the cage body 1.

[0028] The preferred two-panel net 6 and the four sides of the cage body 1 are each provided with colored reflective stickers 12. The colored reflective stickers 12 can effectively attract birds flying at low altitudes to form a visual attraction, so that they can quickly approach the cage body 1 through visual attraction and enter the cage body 1 through the attraction of food.

[0029] The two preferred frames 5 are respectively connected to counterweights at their lower ends. The counterweights are designed to allow birds to quickly return to their original position and form a seal when they enter the cage 1 due to the tilt of the frame 5, thus preventing the birds from escaping from the cage 1. The frames 5 and the netting 6 are made of rigid plastic. The rigid plastic supports the frames 5 and the netting 6, which can effectively reduce their resistance during rotation, allowing birds to enter the cage 1 more quickly.

[0030] The preferred opening and closing component 2 includes a fixed rod 201 fixedly installed above the cage door. Several slacks that can rotate on the fixed rod 201 are evenly spaced on the fixed rod 201. The lower ends of the slacks are vertically connected to a stop bar 202. The lower end of the cage door is provided with a U-shaped groove 15 suitable for the stop bar 202 to enter and exit. The lower ends of the stop bars 202 are fixedly connected to a counterweight ball 203, and the counterweight ball 203 is located below the U-shaped groove 15. Specifically, when a bird passes through the cage door and enters the cage 1 through the inducement of food, the stop bar 202 rotates along the fixed rod 201 as the bird enters, allowing the bird to enter the cage 1. When the bird moves away from the stop bar 202, the counterweight ball 203 connected to the lower end of the stop bar 202 causes the stop bar 202 to reset and enter the U-shaped groove 15 to form a limit. When the bird escapes from the cage 1, it can be blocked by the stop bar 202, ultimately forming a free-closing effect that allows entry but not exit to prevent the bird from escaping.

[0031] The preferred cage 1 has infrared sensors 13 installed on both sides of its lower part. The infrared sensors 13 are connected to a wireless receiver through a controller. The number of birds in the cage 1 can be detected by the infrared sensors 13, and the wireless receiver can inform the staff of the situation in the cage 1, so as to deal with the birds in the cage 1 in time for the continued trapping of birds.

[0032] The preferred cage 1 has a feeding trough 14 in the middle of its bottom surface, wherein the feeding trough 14 is designed to place bird food in a unified manner for easy collection.

[0033] The working principle of this invention is as follows: First, the bird trap is placed in a suitable location according to the airport layout. When birds fly at low altitudes, they are attracted by the visual appeal of the colored reflective sticker 12 or by the food placed in the feeding trough 14 and food holder 7. When the birds pass through the cage door and are induced by the food to enter the cage 1, the barrier 202 rotates along the fixed rod 201 to allow the birds to enter the cage 1. At this time, when the birds move away from the barrier 202, the counterweight ball 203 connected to the lower end of the barrier 202 causes the barrier 202 to reset and enter the U-shaped groove 15 to form a limit. When the birds escape from the cage 1, they can escape through the barrier 202. The structure creates a closed loop that allows birds to enter but not exit, preventing them from escaping. When a bird stands on the stand bar 8 and feeds, its own weight causes the frame 5 to rotate instantaneously to the other side, opening the top of the cage 1 and allowing the bird to fall into it. As the bird enters the cage 1, the frame 5 and the counterweight quickly return to their original position, closing the top of the cage 1 and preventing the bird from escaping. This bird trap has a simple and practical design, improves capture efficiency, effectively controls the number of birds at the airport, reduces safety risks during aircraft takeoff and landing, and does not harm birds or cause environmental pollution.

[0034] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.

[0035] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
