Description

Technical Field

[0001] This application relates to the technical field of protective equipment for disconnecting switches, and more specifically, to bird protection devices for high-voltage AC disconnecting switch mechanisms. Background Technology

[0002] As a critical piece of equipment in substations used to isolate circuits and create visible disconnect points, the reliability of high-voltage AC disconnect switches directly affects the efficiency of switching operations and power supply safety. In outdoor environments, the base or housing of such equipment often becomes a favorite nesting and roosting site for birds. Debris such as twigs, wires, and feathers introduced by birds can easily clog precision transmission gears and connecting rods, leading to disconnect switch malfunctions and various accidents. More seriously, bird droppings are acidic and can corrode metal components, reduce the surface insulation strength of insulators, and potentially cause flashover, short circuits, and other serious accidents, posing a continuous threat to power grid stability. Therefore, effective bird protection for high-voltage AC disconnect switch mechanisms is a long-term and urgent need in the field of substation operation and maintenance.

[0003] The prior art publication CN115777676A provides a bird protection device for a high-voltage AC disconnector mechanism. This device, by setting up a protective cover and installing it on the lower side of the high-voltage AC disconnector mechanism, can effectively prevent birds from entering the mechanism to build nests. While effectively preventing birds from entering the mechanism, it does not lose the original function of the mechanism, nor does it affect the observation of the interior of the mechanism through the opening at the bottom of the mechanism. It has good performance and strongly guarantees the safe operation of the power grid.

[0004] While the aforementioned existing technical solutions offer some bird-repelling effectiveness, they still suffer from the following drawbacks: First, as a localized physical barrier, the protection range of these solutions is limited to the area at the bottom opening of the covered mechanism. Birds can still perch and rest in unprotected areas such as above the protective cover and insulators, and their droppings can still contaminate the critical external insulation parts and transmission components of the equipment, failing to eradicate corrosion and pollution problems. Second, a safety gap must be maintained between the protective cover and the bottom of the mechanism to avoid interference; this gap could easily become a channel for small birds to enter or for debris to fall. Furthermore, such passive isolation devices only address the issue of birds perching and nesting, but cannot actively drive them away, making it difficult to reduce overall bird activity in the equipment area. On the other hand, most commercially available active bird-repelling devices, such as rotating reflectors, ultrasonic generators, and sonic cannons, rely on stimulating the birds' vision and hearing. These methods achieve their purpose by creating unpleasant sound and light signals to drive them away; however, birds are highly intelligent and easily become accustomed to regular, repetitive stimuli that do not cause real harm, leading to a rapid decline in bird-repelling effectiveness over time. In view of this, we propose a bird protection device for high-voltage AC disconnect switch mechanisms. Summary of the Invention

[0005] 1. Technical problems to be solved The purpose of this application is to provide a bird-proof device for a high-voltage AC disconnector switch mechanism, which solves the technical problems of existing technologies that cannot actively drive away birds and whose bird-repelling effect easily decays over time. It realizes a fundamental transformation from passive isolation to active repelling, effectively overcoming the shortcomings of traditional physical barriers that have limited coverage and cannot actively drive away birds. At the same time, the olfactory repelling mechanism has a long-lasting effect, making it difficult for birds to become accustomed to it, thus ensuring the long-term effectiveness of bird repelling.

[0016] 3. Beneficial effects One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages: I. The technical solution of this application, by setting up a medicine storage box, an air duct, and an airflow generating component, drives external air to flow through the installation housing and carries the bird repellent components volatilized from the medicine storage box. The airflow generating component then accelerates the discharge through the air duct, thereby forming a continuous and active odor release and spatial barrier in the area near the disconnecting switch. This effectively overcomes the shortcomings of traditional physical barriers, such as limited coverage and inability to actively repel birds. At the same time, the olfactory repelling mechanism has a long-lasting effect, making it difficult for birds to develop habits, thus ensuring the long-term effectiveness of bird repellency and effectively improving the safety of power grid operation.

[0017] II. The technical solution of this application utilizes natural wind energy to drive the fan blades at high speed by setting up a wind turbine and a centrifugal clutch. The centrifugal clutch engages only when the wind speed reaches a threshold, thus achieving self-powered drive without external power supply. This avoids ineffective wear under light winds, extends the service life of transmission components, and automatically enhances the bird-repelling effect when the wind is strong and birds are more likely to approach the equipment for shelter.

[0018] Third, the technical solution of this application sets up a fan blade so that the dispensing tube can rotate with the wind to change the spray direction of the bird repellent, thus eliminating the blind spot of the fixed airflow direction; at the same time, by setting up a dust baffle and a coil spring, the dust baffle can automatically close when there is no airflow, thereby preventing foreign objects from clogging the dispensing tube and ensuring the long-term smoothness and reliability of the pipeline in harsh outdoor environments.

[0019] Fourth, the technical solution of this application can efficiently collect solar energy and directionally and uniformly heat the medicine in the medicine storage box by setting up a heat-conducting volatilization component, which significantly improves and stabilizes the volatilization rate; at the same time, by setting up a medicine capacity adaptive adjustment mechanism, the surface of the medicine is always kept at the optimal airflow contact height, ensuring the stability of the bird repellent concentration throughout the entire use cycle.

[0020] V. The technical solution of this application, by setting up a rapid bird-repelling component, can use wind power to drive a rotating hammer to intermittently strike the bell during the initial installation of this technical solution or when the effect needs to be enhanced, producing unpredictable sounds. This, together with the continuously released olfactory repelling signals, forms a compound bird-repelling effect, accelerating the disturbance and repulsion of roosting bird flocks, and improving the efficiency of establishing protection.

[0022] The present application will be further described in detail below with reference to the accompanying drawings.

[0023] Reference Figures 1-9 This application discloses a bird-proof device for a high-voltage AC disconnector mechanism, which includes: a mounting housing 1, a medicine storage box 2, a diffusion component 6, and an airflow generating component 7.

[0024] The mounting housing 1 has multiple ventilation holes 101; the medicine storage box 2 is installed inside the mounting housing 1 and is used to hold volatile bird repellent agent. The medicine storage box 2 is densely covered with leakage holes 201; the diffusion component 6 includes multiple air ducts 601, which are connected to the inner cavity of the medicine storage box 2. An air guide pipe 602 is connected to the outside of the air duct 601; the airflow generating component 7 is configured to cause airflow to flow through the interior of the mounting housing 1, carrying the volatile bird repellent agent components, and directionally discharged to the surrounding space of the high-voltage AC disconnect switch through the air guide pipe 602 to form a bird repellent odor barrier.

[0025] Workers add an appropriate amount of granular or block-shaped volatile bird repellent to the storage box 2. After the airflow generating component 7 is activated, outside air enters the housing 1 through the vent 101 on the mounting housing. As the airflow passes through the storage box 2 installed inside the mounting housing 1, it comes into contact with the volatile bird repellent contained in the storage box 2, carrying the effective bird-repelling odor components that evaporate from the surface of the agent. Subsequently, the airflow rich in bird-repelling components is drawn into the air duct 601 and directed to the air guide pipe 602 under air pressure. Then, the airflow is directed and accelerated through the air guide pipe 602 and discharged into the space surrounding the high-voltage AC disconnecting switch mechanism and its key components. By continuously releasing odors that birds dislike, a shift from passive isolation to active bird repellency is achieved, reducing bird activity near the disconnecting switch at its source and solving the problem that traditional physical barriers can only provide local protection and cannot actively repel birds. At the same time, with the directional delivery of the diffusion component 6, a three-dimensional odor barrier can be formed around the insulators and transmission components of the disconnecting switch, providing comprehensive protection and overcoming the blind spots of local protective covers. This olfactory-based deterrence mechanism is long-lasting and difficult for birds to become accustomed to, ensuring its long-term effectiveness and avoiding the degradation of traditional sound and light devices. Furthermore, by actively deterring birds, the risk of bird droppings pollution and corrosion is significantly reduced, thus helping to prevent accidents such as equipment insulation degradation and flashover short circuits, and improving the safety of power grid operation.

[0026] Reference Figure 2 , Figure 5 , Figure 6 and Figure 7 The bird protection device for the high-voltage AC disconnect switch mechanism provided in this application embodiment includes an airflow generating component 7 comprising multiple rotating frames 704, a blower fan blade 706, and a rotating mechanism.

[0027] The rotating frame 704 is fixedly mounted on the mounting housing 1; the fan blade 706 is rotatably mounted on the rotating frame 704, with the air supply side of the fan blade 706 facing the opening end of the air duct 601; the rotating mechanism is used to drive the fan blade 706 to rotate.

[0028] Under the action of the rotating mechanism, the fan blades 706 rotate, and the gas inside the housing 1 then enters the air duct 602 through the air duct 601 and diffuses outward.

[0029] Based on the above solution, the bird-proof device for high-voltage AC disconnect switch mechanism provided in this application embodiment includes a drive rod 701, a windmill 702, a gear column 703, and a drive gear 705 in its rotating mechanism.

[0030] The drive rod 701 is mounted above the mounting housing 1; the impeller 702 is fixedly mounted on the drive rod 701, and the impeller 702 is preferably a Savonius-type vertical axis impeller; the gear column 703 is mounted on one side of the drive rod 701; the drive gear 705 is rotatably mounted on the rotating frame 704 and connected and fixed to the corresponding blower blade 706, the drive gear 705 meshes perpendicularly with the gear column 703, and the diameter of the gear column 703 is larger than the diameter of the drive gear 705, thus forming a speed-increasing transmission pair.

[0031] Under the action of external wind, the wind turbine 702 drives the drive rod 701 to rotate, and the gear column 703 rotates accordingly. Since the drive gear 705 meshes perpendicularly with the gear column 703 and the diameter of the gear column 703 is larger than the diameter of the drive gear 705, the drive gear 705 then drives the blower fan blade 706 to rotate rapidly.

[0032] Based on the above solution, the bird protection device for the high-voltage AC disconnect switch mechanism provided in this application embodiment has a centrifugal clutch installed on the drive rod 701 and the gear column 703.

[0033] When the wind force is small and the wind speed is low, the power transmission between the drive rod 701 and the gear column 703 is disconnected under the action of the centrifugal clutch; when the wind force increases to a set threshold, the drive rod 701 can drive the gear column 703 to rotate through the centrifugal clutch.

[0034] Based on the above solution, the bird protection device for the high-voltage AC disconnect switch mechanism provided in this application embodiment includes a centrifugal clutch comprising a drive inner sleeve 707, at least one connecting rod 709, a centrifugal weight 708, and a spring 710.

[0035] The drive inner sleeve 707 is fixedly installed on the inner wall of the gear column 703; the connecting rod 709 is fixedly installed on the drive rod 701; the centrifugal weight 708 is slidably sleeved on the outside of the connecting rod 709, and the centrifugal weight 708 is driven by friction with the inner wall of the drive inner sleeve 707; the spring 710 is fixedly connected between the centrifugal weight 708 and the connecting rod 709.

[0036] Under the influence of wind from any direction, the Savonius-type vertical axis wind turbine 702 can drive the drive rod 701 to rotate. At low wind speeds, the centrifugal weight 708 is disconnected from the drive inner sleeve 707, and the subsequent transmission chain does not operate, avoiding ineffective or weak movements. When the wind speed increases to a set threshold, under the action of centrifugal force, the centrifugal weight 708 contacts the drive inner sleeve 707, and the power of the drive rod 701 is transmitted to the gear column 703, causing the blower blades 706 to rotate at high speed. This method, which utilizes natural wind energy on-site, eliminates the need for an external power supply or battery, making it particularly suitable for passive or field substation environments. Furthermore, this technical solution only starts when the wind is strong enough, avoiding frequent ineffective movements in light winds, reducing mechanical wear, and extending the device's service life. Moreover, when the wind is strong, birds will instinctively seek shelter and may approach the electrical equipment; at this time, the blower blades 706 rotate at high speed, generating a strong airflow. The stronger the wind and the stronger the airflow, the faster and wider the drug evaporates and diffuses, which precisely enhances the repelling effect on birds when they seek shelter in severe weather.

[0037] Reference Figure 1 , Figure 3 and Figure 4 The bird-proof device for high-voltage AC disconnect switch mechanism provided in this application embodiment has an air duct 602 that is restricted to the outside of the air duct 601 and rotatably connected thereto. Multiple medicine outlet pipes 603 are fixedly connected to the outside of the air duct 602. The diffusion component 6 also includes a driving mechanism for driving the air duct 602 to rotate.

[0038] The drive mechanism includes a fan blade 605, which is fixedly mounted on the air duct 602.

[0039] When there is wind outside, the wind force acts on the fan blade 605, thereby driving the entire air duct 602 together with the medicine outlet tube 603 on it to rotate around the axis of the air intake tube 601. This makes the airflow mixed with bird repellent sprayed from the medicine outlet tube 603 no longer fixed in one direction, but sweeps across the surrounding space over time, eliminating the blind spots that may exist in a fixed airflow direction and improving the comprehensiveness and reliability of bird repellency.

[0040] Based on the above solution, the bird protection device for the high-voltage AC disconnect switch mechanism provided in this application embodiment has an anti-dust mechanism installed on one side of the air outlet end of the medicine pipe 603. The anti-dust mechanism includes a rotating shaft 604, a dust baffle 607, and a coil spring 606.

[0041] The rotating shaft 604 is rotatably mounted on the medicine outlet pipe 603; the dust baffle 607 is fixedly installed on the rotating shaft 604, and its shape is adapted to the inner wall of the medicine outlet pipe 603 and maintains a clearance fit; a coil spring 606 is fixedly connected between the rotating shaft 604 and the medicine outlet pipe 603 to provide a pre-tightening force for closing the dust baffle 607.

[0042] When the device is not in operation, the spring force of the coil spring 606 keeps the baffle plate 607 closed, sealing the outlet of the dispensing pipe 603 and effectively preventing dust, insects, and other foreign objects from entering the dispensing pipe 603. When airflow is released and the air pressure inside the dispensing pipe 603 reaches a certain value, the airflow will force open the baffle plate 607 and discharge the waste. At this time, the baffle plate 607 remains open under the action of the airflow. During shutdown, the baffle plate 607 can isolate external pollution, prevent pipeline blockage, and avoid contamination of the agent, greatly improving the long-term operational reliability of this technical solution in harsh outdoor environments.

[0043] Reference Figure 1 and Figure 3 The high-voltage AC disconnect switch mechanism bird protection device provided in this application embodiment also has several quick bird deterrent components 9 installed on the mounting housing 1. The quick bird deterrent component 9 includes a striking bell 901 and at least one striking hammer 902.

[0044] The striking bell 901 is detachably mounted on the mounting housing 1; the striking hammer 902 is detachably mounted on the corresponding air duct 602, and the striking hammer 902 is in active contact with the striking bell 901.

[0045] During the initial installation of this technical solution or when a stronger bird-repelling effect is needed, workers can install the rapid bird-repelling component 9. When there is wind, the wind-driven fan blade 605 rotates the air duct 602 around its axis. The striking hammer 902 revolves accordingly and collides with the striking bell 901 when it passes the position, thus intermittently striking the striking bell 901 and making it emit a crisp sound. While driving the diffusion of odors, unpredictable intermittent sounds are generated. This sound, combined with the sound of natural wind, can quickly startle and drive away birds that have already perched near the isolation switch during the initial activation of this technical solution. It forms a synergistic compound bird-repelling effect with the continuously released olfactory avoidance signals, accelerating the establishment of the protected area.

[0046] Reference Figure 2 and Figure 8 The bird protection device for the high-voltage AC disconnect switch mechanism provided in this application embodiment is further equipped with a heat-conducting evaporation component 8 on the mounting housing 1. The heat-conducting evaporation component 8 includes a heat-conducting rod 801, a heat transfer base 802, and a heat pipe 805.

[0047] The heat-conducting rod 801 is rotatably mounted on the mounting housing 1. The heat-conducting rod 801 is made of a high thermal conductivity material such as copper, and its outer wall is coated with a dark heat-absorbing coating. The drive rod 701 is fixedly mounted on the heat-conducting rod 801. The heat transfer base 802 is fixedly mounted inside the mounting housing 1. The lower end of the heat-conducting rod 801 is rotatably connected to the heat transfer base 802. The heat transfer base 802 is preferably made of a high thermal conductivity material such as graphene. The heat pipe 805 is preferably a cored heat pipe. The evaporation end of the heat pipe 805 abuts against the heat transfer base 802, and the condensation section of the heat pipe 805 extends into the inner cavity of the medicine storage box 2.

[0048] The heat-conducting rod 801, exposed to sunlight, utilizes its dark heat-absorbing coating to efficiently absorb solar radiation and convert it into heat. Made of highly thermally conductive materials such as copper, the heat rod 801 rapidly conducts heat axially to the heat transfer base 802. The evaporation end of the heat pipe 805 absorbs heat, causing the working fluid inside to evaporate. Under pressure difference, the vapor flows to the condensation section inside the medicine storage box 2, where it condenses and releases heat, directly heating the bird repellent agent inside the medicine storage box 2. The heat pipe 805 enables rapid and directional heat transfer to the interior of the medicine storage box 2, significantly improving the evaporation rate and uniformity of the agent.

[0049] Based on the above solution, the bird protection device for the high-voltage AC disconnect switch mechanism provided in this application embodiment has a heat insulation sleeve 804 fixedly sleeved on one side of the heat-conducting rod 801, and a connecting rod 709 fixedly installed on the heat insulation sleeve 804. The heat insulation sleeve 804 can not only prevent the high temperature of the heat-conducting rod 801 from directly affecting the moving parts such as the drive rod 701 and the connecting rod 709 that are mechanically connected to it, and avoid the mechanism from jamming or being damaged due to thermal expansion or changes in material properties, but also concentrate the heat energy to transfer to the heat transfer base 802, thereby improving the targeted use of heat energy.

[0050] Based on the above solution, the high-voltage AC disconnect switch mechanism bird protection device provided in this application embodiment further includes a heat collection mechanism 8 for the heat conduction and evaporation component 8. The heat collection mechanism includes a plurality of convex lenses 806, and the optical focal points of the convex lenses 806 are set toward the heat conduction rod 801.

[0051] Sunlight, after passing through the convex lens 806, converges at its focal point, generating a localized high-temperature region. This enhances the heating of the heat-conducting rod 801 located in this focal region, significantly increasing its initial heating temperature and efficiency. Moreover, even under conditions of weak sunlight, such as early morning, evening, or cloudy days, sufficient light energy can still be collected for effective heating, extending the effective daily working time of this technical solution.

[0052] Based on the above solution, the bird-proof device for the high-voltage AC disconnect switch mechanism provided in this application embodiment further includes a protective housing 803 covering the convex lens 806. The protective housing 803 is made of a perforated or transparent material to allow light transmission while preventing external flammable materials from entering the focal area and causing a fire. The protective housing 803 not only prevents damage to the convex lens 806 but also, while ensuring the heat collection function, fundamentally eliminates the fire hazard caused by the potential ignition of external flammable materials by focused sunlight, greatly improving the safety of outdoor power equipment accessories.

[0053] Based on the above solution, the bird protection device for the high voltage AC disconnect switch mechanism provided in this application embodiment has a heat storage sleeve 807 sleeved on the outside of the condensing section of the heat pipe 805. The heat storage sleeve 807 has a hollow structure and its internal cavity is filled with phase change energy storage material. The heat storage sleeve 807 is made of a material with good thermal conductivity.

[0054] When the condenser section of heat pipe 805 releases heat, some of the heat is absorbed by the shell of heat storage sleeve 807 and conducted to the phase change energy storage material filled inside, causing it to undergo a phase change, such as a solid-liquid phase change, to store the heat. When sunlight stops or weakens, and the heat transfer capacity of heat pipe 805 decreases, the phase change material undergoes a reverse phase change process, slowly releasing the stored heat to continue heating the area of ​​drug storage box 2. This avoids temperature fluctuations caused by changes in sunlight, making the drug evaporation rate more stable.

[0055] Reference Figure 2 , Figure 8 and Figure 9 The bird-proof device for high-voltage AC disconnect switch mechanism provided in this application embodiment has a medicine capacity adaptive adjustment mechanism in the medicine storage box 2. The medicine capacity adaptive adjustment mechanism includes a support plate 3, a volume adjustment plate 5, and an elastic element 10.

[0056] The supporting plate 3 is horizontally set in the inner cavity of the medicine storage box 2 and is slidably connected to the inner wall of the medicine storage box 2 to hold volatile bird repellent; the volume adjustment plate 5 is located below the medicine storage box 2 and is slidably inserted through the bottom of the medicine storage box 2 and maintains a sliding fit with the inner wall of the mounting shell 1; the elastic element 10 is fixedly connected between the volume adjustment plate 5 and the medicine storage box 2.

[0057] Initially, the medicine storage box 2 is filled with medicine, and the support plate 3, due to its heavy load, is positioned at a lower level, overcoming the elastic force of the elastic element 10 to press the volume adjustment plate 5 to its lower limit. At this time, the airflow channel space above the medicine storage box 2 is relatively large. As the bird repellent medicine continues to evaporate and be consumed, its total mass gradually decreases. The gravity on the support plate 3 and the medicine on it decreases accordingly. Under the restoring elastic force of the elastic element 10, the volume adjustment plate 5 is pushed upward and slides, simultaneously causing the support plate 3 to move upward slowly. This causes the cavity volume above the medicine storage box 2 to gradually decrease. In this way, regardless of the amount of medicine remaining, the upward movement of the support plate 3 ensures that the upper surface of the medicine is always kept within a specific height range close to the airflow channel, thereby ensuring that the effective contact area between the flowing airflow and the medicine, as well as the concentration of volatile components carried, remain relatively stable, avoiding the decrease in bird repellent efficacy due to the reduction of medicine.

[0058] Based on the above solution, the bird protection device for the high voltage AC disconnect switch mechanism provided in this application embodiment has a maintenance door plate 4 hinged to one side of the housing 1, and an observation plate 11 is embedded and fixed on the maintenance door plate 4. The observation plate 11 is made of transparent material.

[0059] Without disassembling the housing 1, staff can directly observe the position of the volume adjustment plate 5 from the outside through the observation panel 11, thereby quickly determining the remaining amount of the reagent and the stage of use. This facilitates the planning of maintenance cycles and reagent replenishment times, greatly improving the maintainability and operational efficiency of the equipment.

[0060] The implementation principle of the bird-proof device for the high-voltage AC disconnect switch mechanism in this application embodiment is as follows: When relevant personnel need to use this technical solution to prevent birds from entering the high-voltage AC disconnect switch, the personnel first install this device on or near the disconnect switch base, and fill the medicine storage box 2 with a sufficient amount of granular or block volatile bird repellent.

[0061] A natural breeze blows onto the wind turbine 702. When the wind speed reaches a set threshold, the centrifugal weight 708 contacts the drive sleeve 707, and the power of the drive rod 701 is transmitted to the gear column 703. The fan blades 706 rotate at high speed, generating negative pressure, which allows outside air to enter the housing through the vent 101. The outside air flows through the medicine storage box 2, carrying the bird repellent agent, and is sprayed outward through the medicine outlet pipe 603. During this period, the natural wind drives the fan blades 605 to rotate the air guide pipe 602, spraying the agent to various locations.

[0062] After sunlight is focused by the convex lens 806, it shines on the heat-conducting rod 801, heating the rod. The heat is then transferred to the heat pipe 805 via the heat transfer base 802, and then into the medicine storage box 2, accelerating the evaporation of the medicine.

[0063] During use, staff can periodically check the position of the volume adjustment plate 5 through the observation panel 11 to determine the remaining amount of the medicine. When the medicine is about to run out, staff can open the maintenance door panel 4 to replenish it.
