Description

Technical Field

[0001] This utility model relates to the field of bird deterrence equipment technology, and in particular to a wind-driven bird deterrence device for power transmission towers. Background Technology

[0002] As a critical facility in the power transmission network, the safe and stable operation of power transmission towers is of paramount importance. However, birds frequently roost and nest on these towers, and their droppings can contaminate insulator strings, reducing insulation performance and potentially causing flashover tripping, threatening power grid safety. Furthermore, conductive materials such as wires that may be trapped in bird nests also pose a significant short-circuit hazard.

[0003] To drive away birds, the power industry has adopted a variety of bird deterrent devices. Among them, active bird deterrents, such as devices that use reflection or sound to scare away birds, have been used to some extent. However, many existing such devices rely on a single bird deterrent method in their design, such as simply reflecting light or simply emitting a fixed sound to frighten birds.

[0004] This single stimulus method has a significant drawback: birds are prone to adaptation after prolonged exposure. For a fixed, unchanging stimulus with no real threat, birds will gradually lower their vigilance and eventually regard it as part of the environment and no longer avoid it. As a result, the effectiveness of bird deterrent devices will decrease significantly over time, making it impossible to achieve long-term effective bird deterrence.

[0005] Furthermore, these active bird deterrent devices typically require an energy supply to operate. Providing a stable and reliable power source for power transmission towers scattered throughout mountainous and remote areas is itself a challenge. Battery power requires regular manual replacement, resulting in significant maintenance workload and high costs. Solar power, on the other hand, is greatly affected by weather conditions, and the panels are easily covered by dirt, leading to insufficient reliability. Therefore, designing a bird deterrent that can overcome bird adaptability while achieving energy self-sufficiency and long-term maintenance-free operation is a pressing technical problem that needs to be solved in this field.

[0006] Therefore, this utility model proposes a wind-driven bird deterrent for power transmission towers to address the shortcomings of existing technologies. Utility Model Content

[0007] In view of the problems of existing wind-driven bird deterrents for power transmission towers, such as the single bird deterrent method leading to bird adaptability, dependence on external energy, and inconvenience in maintenance, this utility model aims to provide a wind-driven bird deterrent for power transmission towers with an improved structure that can effectively solve the above problems.

[0008] This utility model provides a wind-driven bird deterrent for power transmission towers, comprising: a fixed plate, a column vertically fixedly connected to the fixed plate, a rotating shaft rotatably connected to the column, a first connecting rod fixedly connected to the rotating shaft, a blade fixedly connected to the end of the first connecting rod, a bird deterrent component fixedly connected to the rotating shaft, a hollow iron box connected to the column, and an adjustment component connected to the column.

[0009] The bird deterrent assembly includes a connecting post, a first spring, and a striking ball. One end of the connecting post is fixedly connected to the rotating shaft, and the other end is connected to the striking ball via the first spring.

[0010] Furthermore, the hollow iron box and the bird deterrent component are combined in the following spatial relationship: the hollow iron box is located on the movement path formed by the ball as the rotating shaft rotates, and the adjustment component includes a reflector. The rotating shaft is driven by wind power to achieve periodic striking of the bird deterrent component and the hollow iron box, while simultaneously driving the reflector to rotate, forming a dual sound and light bird deterrent effect.

[0011] Preferably, a first sleeve is fixedly connected to the outer wall of the column, and a hollow iron box is fixedly connected to the first sleeve through a second connecting rod.

[0012] Preferably, the adjustment assembly further includes a second sleeve and a third connecting rod, with the reflector fixed to the third connecting rod and the second sleeve hinged to the column via the third connecting rod.

[0013] Preferably, the adjusting assembly further includes a connecting block, and the second sleeve is hinged to the connecting block.

[0014] Preferably, the adjustment assembly further includes a handle and a pin, the handle being slidably connected to the pin, and one end of the pin being pluggably engaged in a limiting hole in the inner wall of the third link to lock or unlock the angle of the third link.

[0015] Preferably, the adjustment assembly further includes a limiting post and a second spring. The limiting post is slidably disposed within the connecting block and fixedly connected to the handle. The second spring is sleeved on the outer periphery of the limiting post, and the two ends of the second spring abut against the inner wall of the connecting block and the pin, respectively.

[0016] Preferably, the handle is used to drive the limiting post to slide within the connecting block, thereby compressing the second spring and causing the pin to disengage from the inner wall of the third link, thus achieving angle adjustment.

[0017] Preferably, a wind-driven bird deterrent for power towers further includes a threaded rod passing through a fixing plate for fastening the fixing plate to the cross arm of the power tower.

[0018] This utility model has the following beneficial effects: 1. This utility model solves the problems of single function and poor bird-repelling effect caused by birds' easy adaptation in existing bird repellers by setting a wind-driven rotating shaft and linking it with a bird-repelling component that can knock on a hollow iron box and a reflector. It achieves the dual effect of sound and light bird repelling, which can form a continuous compound stimulus to birds and significantly improve the breadth and persistence of bird repelling.

[0019] 2. This utility model, by setting an adjustment component with a handle, a pin and a spring, realizes the manual adjustment and locking function of the reflector angle, which solves the problem that the existing reflective bird deterrent device has a fixed angle and cannot be optimized according to seasonal and light changes, resulting in unstable bird deterrent effect. It achieves the effect of dynamically optimizing the light reflection angle, maximizing the visual bird deterrent effect and improving the bird deterrent efficiency of the device at different times and in different seasons.

[0020] 3. This utility model, by setting up blades, uses natural wind energy to drive the entire device, which solves the problems of existing bird deterrents relying on external power sources, having high maintenance costs, and being unsuitable for remote environments without electricity. It achieves the goal of energy self-sufficiency and zero-energy operation, reduces the difficulty and cost of later maintenance, and enhances the environmental adaptability of the device.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] Example: Please refer to Figures 1 to 4 This utility model provides a wind-driven bird deterrent for power transmission towers, which aims to solve the problems of existing bird deterrents having limited functions, relying on external energy, and having fixed structures that cannot adapt to environmental changes.

[0025] like Figure 1 and Figure 2 As shown, the wind-driven bird deterrent for power towers includes a fixed plate 1 and a column 3 vertically fixed to the fixed plate 1. The fixed plate 1 serves as the mounting base for the entire device, and the column 3 supports the main structure of the device. A rotating shaft 4 is rotatably connected to the column 3, and a first connecting rod 5 is fixedly connected to the rotating shaft 4. A blade 6 is fixedly connected to the end of the first connecting rod 5. When the wind drives the blade 6 to rotate, the rotating shaft 4 rotates synchronously through the first connecting rod 5, providing power for the entire device. A bird deterrent assembly 7 is also fixedly connected to the rotating shaft 4. The bird deterrent assembly 7 includes a connecting column 701, a first spring 702, and a striking ball 703. One end of the connecting column 701 is fixedly connected to the rotating shaft 4, and the other end is connected to the striking ball 703 through the first spring 702. A hollow iron box 706 is connected to the column 3. The hollow iron box 706 is located on the movement path formed by the striking ball 703 when the rotating shaft 4 rotates, so that the striking ball 703 can periodically strike the hollow iron box 706 during the rotation of the rotating shaft 4. As a specific installation method, a first sleeve 704 is fixedly connected to the outer wall of the column 3. The first sleeve 704 is fixedly connected to a hollow iron box 706 through a second connecting rod 705. In addition, an adjustment component 8 is also connected to the column 3. The adjustment component 8 includes a reflector 801, which is used to achieve visual bird deterrence.

[0026] To achieve flexible adjustment and reliable fixation of the angle of the reflector 801, the core of the technical solution in this embodiment lies in the unique locking and unlocking structure inside the adjustment component 8. Please refer to the following for details. Figure 1 , Figure 3 and Figure 4 The structure of the adjustment component 8 will be described in detail below: Adjustment assembly 8 includes a second sleeve 802 and a third connecting rod 803. The reflector 801 is fixed to the third connecting rod 803. The second sleeve 802 is hinged to the column 3 via the third connecting rod 803, thus providing a basis for the reflector 801 to have an adjustable angle. To lock the adjusted angle, adjustment assembly 8 also includes a connecting block 804. The second sleeve 802 is hinged to the connecting block 804. Adjustment assembly 8 also includes a handle 805 and a pin 806 for performing a locking action. The handle 805 and the pin 806 are slidably connected. One end of the pin 806 is pluggably engaged in a limiting hole on the inner wall of the third connecting rod 803. When the pin 806 is inserted into the limiting hole... When the pin is in position, the angle of the third link 803 is locked. To achieve automatic reset and convenient operation of the pin 806, the adjustment assembly 8 also includes a limiting post 807 and a second spring 808. The limiting post 807 is slidably disposed in the connecting block 804 and fixedly connected to the handle 805. The second spring 808 is sleeved on the outer periphery of the limiting post 807, and the two ends of the second spring 808 abut against the inner wall of the connecting block 804 and the pin 806, respectively. This structure allows the limiting post 807 to slide in the connecting block 804 when the handle 805 is pulled, thereby compressing the second spring 808 and causing the pin 806 to disengage from the inner wall of the third link 803, thus unlocking the pin.

[0027] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred installation and fixing method, in order to securely install the entire device on the power tower, a threaded rod 2 is also included, which passes through the fixing plate 1. The threaded rod 2 is used to fasten the fixing plate 1 to the cross arm of the power tower, ensuring the structural stability of the device in strong wind or vibration environments.

[0028] The working principle of this utility model of wind-powered bird deterrent for power transmission towers is as follows: When the natural wind blows the blade 6, the blade 6 is driven to rotate by the wind force, and drives the rotating shaft 4 to rotate synchronously through the first connecting rod 5. As the rotating shaft 4 rotates, the bird deterrent component 7 fixed on the rotating shaft 4 starts to work. The striking ball 703 generates periodic reciprocating motion under the combined action of the elastic recovery of the first spring 702 and centrifugal inertia, and continuously strikes the outer wall of the hollow iron box 706 fixed on the column 3, thereby producing a continuous and rhythmic sound to achieve acoustic bird deterrence.

[0029] When the angle of the reflector 801 needs to be adjusted, the operator pulls the handle 805, causing the limiting post 807 to slide on the inner wall of the connecting block 804, thereby compressing the second spring 808 and causing the pin 806 to disengage from the limiting hole on the inner wall of the third link 803. At this time, the tilt angle of the reflector 801 can be freely adjusted. When the appropriate position is reached, the handle 805 is released, the second spring 808 rebounds, and pushes the pin 806 to automatically reset and re-insert into the limiting hole, thus completing the firm fixation of the angle of the reflector 801 to meet the visual bird deterrence needs in different environments.

[0030] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
