Abstract
Description
Technical Field
[0001] This utility model relates to the technology and field of bird deterrence equipment, and in particular to a rotating fixing device for a bird deterrence cannon. Background Technology
[0002] Bird deterrent cannons are widely used in bird control operations at major airports both domestically and internationally. By using these cannons, airports can effectively reduce bird strikes, ensuring aviation safety and smooth operations. Furthermore, bird deterrent cannons are also suitable for other locations requiring bird control, such as farmland and orchards.
[0003] The existing mainstream bird deterrence equipment mainly uses acoustic (such as sonic bird deterrents) or optical (such as laser bird deterrents and terror eyes) principles to deter birds. These devices are easily adapted to by birds after repeated use, so it is difficult to achieve the goal of bird deterrence by sound and optical effects alone. Moreover, these devices will bring unnecessary sound and light pollution to the airport and the surrounding environment, and may even have a certain impact on operators and nearby residents.
[0004] Some airports have begun using solid projectiles to scare away birds. Two-stage firecrackers and titanium-plated firecrackers are two of the most commonly used bird-scare projectiles. They generally employ a two-stage gunpowder ignition process. Direct ignition achieves the first stage of explosive propulsion, propelling the projectile towards the bird. The second stage of explosion occurs in mid-air near the bird, producing a multi-sensory effect including sound, flash, and shockwave. Years of practical application have shown that this type of bird-scare projectile is currently the most effective, efficient, and least adaptable method for bird control.
[0005] In practical use, the bird deterrent cannon is mounted on a mounting bracket. This bracket is a crucial component for fixing and supporting the bird deterrent projectile launching device, and its design and installation methods vary depending on the application scenario and specific requirements. Existing mounting brackets include those with fixed angle installation, adjustable installation, or portable installation, with adjustable mounting brackets being the most widely used. However, adjustable mounting brackets suffer from problems such as inconvenient adjustment, limited adjustment range, and poor stability.
[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

Detailed Implementation
[0020] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.
[0021] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.
[0022] like Figures 1 to 3 As shown, a rotating fixing device for a bird-repelling cannon according to a specific embodiment of this utility model includes a first base 1 and a second base 2. The bird-repelling cannon 3 is rotatably connected to the first base 1 and the second base 2 and is located between the first base 1 and the second base 2. The angle of the bird-repelling cannon 3 can be adjusted by rotating it to adapt to different operational needs.
[0023] The specific structure is as follows: A sleeve 21 is provided on the second base 2, and a rotating shaft (not shown in the figure) is provided inside the sleeve 21. The right end of the rotating shaft is connected to the bird deterrent cannon 3. The rotating fixing device also includes an angle limiting plate 4, a rotating sleeve 5, a limiting pin 6, a handle 7, and a pin 8. The angle limiting plate 4 is provided on the first base 1 and is fitted to the first base 1. The angle limiting plate 4 is provided with a through arc-shaped limiting groove 41 and multiple pin limiting holes. The arc of the limiting groove 41 is a quarter circle arc and is located in the third quadrant of the coordinate system. In this embodiment, there are three pin limiting holes, namely the first pin limiting hole 42, the second pin limiting hole 43, and the third pin limiting hole 44. The three pin limiting holes are distributed along the outer edge of the limiting groove 41. The first pin limiting hole 42 is located near the upper end of the limiting groove 41, and the second pin limiting hole 43 and the third pin limiting hole 44 are located near the middle and lower sections of the limiting groove 41.
[0024] A rotating sleeve 5 is mounted on the first base 1. A horizontally positioned rotating shaft 51 is located inside the rotating sleeve 5. The front end of the rotating shaft 51 extends beyond the front end of the rotating sleeve 5 and is connected to the bird deterrent cannon 3. A limiting pin 6 is connected to the rear end of the rotating sleeve 5, and its front end is slidably positioned within a limiting groove 41. The front end of the limiting pin 6 is always positioned within the limiting groove 41. When the bird deterrent cannon 3 rotates, the limiting pin 6 slides within the limiting groove 41, providing support for the angle limiting plate 4 and preventing it from falling off. A handle 7 is rotatably connected to a handle rotating shaft 9 via a connecting piece 71. The handle rotating shaft 9 is vertically positioned on the rotating sleeve 5. One end of the connecting piece 71 is connected to the handle rotating shaft 9, and the other end is connected to the handle 7. The rear end of a pin 8 is movably connected to the handle 7 via a connecting rod 10. One end of the connecting rod 10 is hinged to the rear end of the pin 8 via a rotating shaft, and the other end is hinged to the handle 7 via a rotating shaft. The front end of the pin 8 is set to correspond to the pin limiting hole in a horizontally movable insertion or withdrawal manner.
[0025] The method for adjusting the angle of the bird deterrent cannon using the rotating fixing device of this utility model is as follows: Initially, the pin 8 is inserted into the first pin limiting hole 42, and the bird deterrent cannon 3 is at a horizontal angle. Move the handle 7 to the right, and the connecting piece 71 drives the handle rotating shaft 9 to rotate. The connecting rod 10 pulls the pin 8 horizontally, and the pin 8 moves away from the first pin limiting hole 42. Rotate the handle 7 downwards, and the limiting pin 6 slides in the limiting groove 41, causing the bird deterrent cannon 3 to rotate around the rotating shaft on the first base 1 and 2. When it moves to the second pin limiting hole 43, move the handle 7 to the left, and the pin 8 moves to the left, inserting into the second pin limiting hole 43, thus fixing the bird deterrent cannon 3 at this angle. In this embodiment, when rotated to the second pin limiting hole 43, the cannon body of the bird deterrent cannon 3 forms an 80° angle with the horizontal. Using the same handle operation method, rotate pin 8 to the third pin limiting hole 44. When the pin is inserted into the third pin limiting hole, the cannon body of the bird deterrent cannon 3 forms a 100° angle with the horizontal line. This utility model's device consists of a pin, an angle limiting plate, a handle rotation shaft, a handle, and a limiting pin. By rotating the handle, the position of the pin inserted into the pin limiting hole on the angle limiting plate is adjusted to adjust the angle of the bird deterrent cannon. The limiting pin always slides within the limiting groove, preventing the bird deterrent cannon from falling. In other words, this utility model's rotating fixing device can adjust the rotation angle of the bird deterrent cannon at multiple angles according to actual working needs, while also preventing the bird deterrent cannon from falling. The equipment operates stably and is simple to operate.
[0026] Preferably, the rotating sleeve 5 is provided with a mounting frame 52, and the handle rotation shaft 9 is vertically arranged inside the mounting frame 5. The connecting member 71 is an L-shaped connecting rod, with one end sleeved on the handle rotation shaft 9 and the other end connected to the handle 7. With the mounting frame 52, when the handle 7 is turned to the right, the connecting rod moves to the right. The mounting frame 52 limits the horizontal movement of the connecting rod, preventing excessive horizontal movement and thus avoiding the pin 8 from falling off.
[0027] Preferably, the rotating sleeve 5 is fixedly provided with a connecting plate 53. The front end of the connecting plate 53 is fixedly provided on the rotating sleeve 5, and the rear end extends towards the rear end of the first base 1. The connecting plate 53 is provided with a through pin sleeve 54. The front end of the pin 8 extends into the pin sleeve 54, and the rear end is movably connected to the handle 7 through a connector 71. With the pin sleeve 54 provided, when the pin 8 moves horizontally and disengages from the pin limiting hole, the pin 8 is placed inside the pin sleeve 54, with its front end located inside the pin sleeve 54 or flush with the front end of the pin sleeve 54. When the pin 8 moves horizontally, it can make the pin 8 move smoothly and along a horizontal straight line, avoiding the pin 8 from falling off during horizontal movement.
[0028] Preferably, the rear end of the limiting pin 6 is fixedly connected to the connecting plate 53.
[0029] Preferably, the rear end of the rotating sleeve 5 is provided with a sleeve pin retaining plate 55, which is used to fix the rotating shaft 51 and restrict the horizontal movement of the rotating shaft 51 to the right.
