Abstract
Description
Technical Field
[0001] This utility model relates to the field of navigation mark technology, specifically a novel navigation mark bird deterrent needle. Background Technology
[0002] Bird deterrents are devices used to prevent birds from perching or flying on navigation lighthouses. These deterrents are typically designed with visual or physical barriers to effectively scare away birds and prevent them from interfering with shipping.
[0003] Existing bird deterrents typically employ a fixed structure, such as mounting the needle to a rigid navigation light fixture. This design can easily lead to birds adapting to the fixed obstacle over time and no longer feeling threatened. For example, when the position and angle of the bird deterrent remain unchanged, the birds' alertness gradually decreases, resulting in a significant reduction in its bird deterrent effect. Utility Model Content
[0004] In view of the shortcomings of the existing technology, this utility model provides a new type of bird deterrent needle for navigation marks.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows:
[0006] The new type of bird deterrent needle includes:
[0007] The navigation light fixture has several semi-circular grooves evenly spaced in a ring on its top horizontal surface.
[0008] Multiple semi-circular concave mounting bases are fixed in each groove, and an annular buffer gap is left between the top of each mounting base and the top edge of the groove.
[0009] The bird deterrent needle is axially inserted into the annular buffer gap, and its bottom core is rolled and sleeved in the mounting base. When the tip of the bird deterrent needle is touched by a bird, its bottom core rolls in the mounting base, causing the bird deterrent needle to tilt in any direction of the buffer gap.
[0010] The bird-repelling needle automatically resets through the limiting effect of the annular buffer gap and the rolling inertia of the core, forming a continuous, irregularly swaying roly-poly effect to dynamically repel birds.
[0011] Preferably, when the bird deterrent needle is tilted by an external force, its sidewall presses against the inner edge of the annular buffer gap, causing the gap cross section to dynamically deform from an initial rectangle into an acute triangle.
[0012] Preferably, when the bird deterrent needle is tilted, a ring of elastic buffer layer is formed at the contact portion with the buffer gap, and the outer surface of the buffer layer and the outer wall of the bird deterrent needle in the perpendicular state are on the same conical surface.
[0013] Preferably, the bottom core of the bird-repelling needle is a counterweight encased in a stainless steel shell, and the counterweight coincides with the axis of the bird-repelling needle.
[0014] Preferably, the gap between adjacent grooves allows for non-contact swinging between adjacent bird deterrent needles.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] This invention utilizes the tilting and free movement of a bird-repelling needle to create a self-righting effect. When the bird-repelling needle is touched by a bird, it produces irregular and continuous shaking. Relying on the inertia of the annular buffer gap and the core, it achieves self-reset. This dynamic shaking and instability makes it difficult for birds to adapt, thus effectively driving away birds. Attached Figure Description

[0023] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0024] Example
[0025] like Figures 1-4 As shown, the new type of bird deterrent needle for navigation includes:
[0026] The navigation light fixture 1 has several semi-circular grooves 11 evenly spaced in a ring on its top horizontal surface;
[0027] Multiple semi-circular concave mounting bases 2 are fixed in each groove 11, and an annular buffer gap is left between the top of each mounting base 2 and the top edge of the groove 11.
[0028] The bird deterrent needle 3 is axially inserted into the annular buffer gap, and its bottom core is rolled and sleeved in the mounting base 2. When the top of the bird deterrent needle 3 is touched by a bird, its bottom core rolls in the mounting base 2, causing the bird deterrent needle 3 to tilt in any direction of the buffer gap.
[0029] The bird deterrent needle 3 automatically resets through the limiting effect of the annular buffer gap and the rolling inertia of the core, forming a continuous irregular shaking roly-poly effect to dynamically deter birds.
[0030] When a bird touches the tip of the bird deterrent needle 3, it shifts axially, causing its core to roll within the mounting base 2. This results in the needle tilting in any direction within the buffer gap. The inertia of the needle within the annular buffer gap ensures it doesn't remain at a fixed angle but repeatedly bounces back. This continuous, irregular shaking creates minute dynamic changes in the needle, making birds perceive environmental instability. Birds are extremely sensitive to environmental changes, especially when their surroundings are constantly shifting, causing them anxiety. Due to the irregular and continuous shaking of the needle, birds cannot adapt to these changes and will leave the area. Compared to traditional static physical barriers (such as nets or spikes), the roly-poly effect creates dynamic, constantly changing pressure to drive birds away, preventing them from adapting or habitually staying. The automatic reset function of the needle ensures this effect continues, constantly increasing the birds' discomfort.
[0031] like Figure 4 As shown, when the bird deterrent needle 3 is tilted under external force, its sidewalls compress the inner edge of the annular buffer gap, causing the gap's cross-section to dynamically deform from an initial rectangle into an acute-angled triangle. This design further increases the elastic feedback between the bird deterrent needle 3 and the annular buffer gap, making the bird deterrent needle 3's response more flexible and adaptable. This dynamic deformation allows the bird deterrent needle 3 to adjust its response according to changes in external force, increasing the randomness and uncertainty of the bird deterrence process, thereby effectively preventing bird habituation and adaptation.
[0032] like Figure 4As shown, when the bird deterrent needle 3 is tilted, a ring of elastic buffer layer 31 is formed at the contact portion with the annular buffer gap, and the outer surface of the buffer layer 31 is on the same conical surface as the outer wall of the bird deterrent needle 3 when it is perpendicular. The formation of an elastic buffer layer 31 at the contact portion between the bird deterrent needle 3 and the annular buffer gap makes the contact with the annular buffer gap softer and more adjustable. When the bird deterrent needle 3 is tilted, the buffer layer 31 is compressed, and this feedback mechanism further enhances the effect of dynamic shaking and enhances the bird deterrent needle 3's responsiveness to external forces.
[0033] like Figure 3 As shown, the bottom core of the bird deterrent needle 3 is a counterweight encased in a stainless steel shell, and the counterweight coincides with the axis of the bird deterrent needle 3. The gaps between adjacent grooves 11 allow for non-contact swinging between adjacent bird deterrent needles 3. When a bird touches one of the bird deterrent needles 3, the bottom core of the bird deterrent needle 3 will tilt due to its inertia and weight. When the bird deterrent needle 3 tilts, it maintains a non-contact state with the gaps between adjacent grooves 11, ensuring that the movement of each bird deterrent needle 3 does not interfere with the movement trajectory of other bird deterrent needles 3. Therefore, the swaying of the bird deterrent needle 3 remains irregular and continuous.
[0034] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
