Description

Technical Field

[0001] This invention relates to the technical field of protective equipment for power transmission towers, and more particularly to a bird deterrent device for power transmission towers. Background Technology

[0002] Currently, in the field of power transmission tower protection equipment, bird deterrents are typically installed on power towers to prevent birds from nesting or perching on them and causing short circuits or other faults. Most existing bird deterrents are fixed high up on the towers, requiring workers to climb to a height for close-range operation during routine inspections or maintenance. This high-altitude work method is not only inconvenient and time-consuming but also poses significant safety hazards, easily leading to falls. Therefore, there is an urgent need for a bird deterrent device for power towers that allows for safe operation from the ground and reduces maintenance difficulty and risks. Summary of the Invention

[0003] The present invention aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, the purpose of this invention is to propose a bird deterrent device for iron towers, which uses a lifting frame and a winch to achieve controllable lifting of the bird deterrent device body, so as to facilitate the safe maintenance of the bird deterrent device body by workers on the ground.

[0005] To achieve the above objectives, this invention proposes a bird deterrent device for iron towers, comprising a base, a bird deterrent device body, and a lifting frame. The base is disposed under the lifting frame, and the bird deterrent device body is movably disposed on one side of the lifting frame. The lifting frame has a partition, and a guide wheel is installed on the top of the partition. A cable is mounted on the guide wheel, and a winch is located at the bottom of the lifting frame. The cable connects the bird deterrent device body and the winch respectively. The winch controls the lifting and moving of the bird deterrent device body through the cable, facilitating maintenance of the bird deterrent device body by staff.

[0006] In addition, the iron tower bird deterrent proposed according to the present invention may also have the following additional technical features:

[0007] Specifically, the top of the partition is provided with a notch structure, and the guide wheel is fixed inside the notch structure.

[0008] Specifically, the lifting frame is symmetrically provided with vertical rods, and a sliding collar is movably sleeved on the vertical rods, and the sliding collar is fixedly connected to the bird deterrent body.

[0009] Specifically, a sleeve is connected to one side of the bird deterrent device body, the sleeve is fitted onto the cable, and the sleeve is connected to a sliding collar.

[0010] Specifically, the sleeve is symmetrically fitted with sleeve plates, which are disposed on the outer side of the bird repeller body.

[0011] Specifically, a connecting rod is provided between the sleeve and the sliding collar, and the connecting rod is disposed between the sleeve plates.

[0012] Specifically, a slider is provided between the sleeve plate and the bird deterrent body. The slider has an I-shaped structure and moves through the lifting frame.

[0013] Specifically, the vertical rod and the winch are respectively located on both sides of the partition.

[0014] Specifically, the bird deterrent device body is provided with an auxiliary wheel on the side near the lifting frame, and the auxiliary wheel is rolled on the outer surface of the lifting frame.

[0015] Specifically, the sleeve, connecting rod, and sliding collar are respectively provided.

[0016] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0017] By installing partitions and guide wheels inside the lifting frame, and a winch at the bottom, with cables connecting the winch to the bird deterrent body, the winch can control the bird deterrent body's lifting and lowering movement along the lifting frame by winding and unwinding the cable. When maintenance is required, workers can use the winch to lower the bird deterrent body to a lower position, avoiding the risks of climbing the tower for high-altitude work and achieving safe and convenient maintenance operations. Simultaneously, the vertical rods and sliding collars inside the lifting frame provide stable sliding guidance for the bird deterrent body's lifting and lowering, preventing swaying during the process; the partitions separate the vertical rods and winch on both sides, rationally planning the internal space layout of the lifting frame and preventing interference between the cables and the sliding structure; auxiliary wheels on the side of the bird deterrent body roll on the outer side of the lifting frame, further ensuring a smooth and stable lifting process, significantly improving the efficiency and safety of equipment maintenance.

[0025] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention. Rather, embodiments of the invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0026] Example 1:

[0027] like Figure 1-4 As shown, this embodiment provides a bird deterrent device for iron towers. The bird deterrent device includes a base 1, a bird deterrent device body 2, and a lifting frame 3.

[0028] The base 1 is located below the lifting frame 3. Specifically, the base 1, as the supporting structure of the entire bird deterrent system, is usually fixed to the crossarm or main structure of the tower by fasteners, providing a stable bottom support for the lifting frame 3.

[0029] It should be understood that although the layout of the base 1 located directly below the lifting frame 3 is shown in this embodiment and the accompanying drawings, in other embodiments, the base 1 may also be laterally connected to the bottom edge of the lifting frame 3 according to the specific installation space conditions of the tower, as long as it can provide reliable anchoring for the lifting frame 3.

[0030] The bird deterrent device body 2 is movably mounted on one side of the lifting frame 3.

[0031] Specifically, the bird repeller body 2 is the core functional module for performing bird repeller functions. It can integrate bird repeller components such as ultrasonic generators, voice playback modules, flashlights, or rotating reflectors. Unlike traditional equipment that is statically fixed high up on the tower, the bird repeller body 2 is suspended or attached to the side of the lifting frame 3 in a way that allows it to move relative to the lifting frame 3, thus enabling it to move vertically.

[0032] The lifting frame 3 is equipped with a partition 4. A guide wheel 5 is installed on the top of the partition 4. A cable 6 is installed on the guide wheel 5. A winch 7 is installed at the bottom of the lifting frame 3. The cable 6 connects the bird repeller body 2 and the winch 7 respectively. The winch 7 controls the lifting and moving of the bird repeller body 2 through the cable 6, which facilitates the maintenance of the bird repeller body 2 by the staff.

[0033] Specifically, the lifting frame 3 constitutes the track frame for the lifting movement of the bird repeller body 2 and the protective shell for its internal components. The partition 4 extends along the interior of the lifting frame 3, not only enhancing the structural rigidity of the lifting frame 3 frame but also serving as the mounting base for the guide wheel 5. The guide wheel 5 is positioned in the top area of ​​the partition 4, changing the direction of force transmission of the cable 6. The winch 7, as the power source, is located at the bottom of the lifting frame 3, and its interior contains components such as a motor and a drum. One end of the cable 6 is wound and fixed to the drum of the winch 7, while the other end extends upward, passes around the guide wheel 5 at the top of the partition 4, turns downward, or connects to the top or side wall connection point of the bird repeller body 2, forming a complete power transmission path of "winch 7 - cable 6 - guide wheel 5 - bird repeller body 2".

[0034] The working mechanism and core advantages of this embodiment are as follows: When the bird repeller body 2 needs to be lowered to the vicinity of the ground for maintenance, the operator starts the winch 7 at a low position to perform the cable release operation. The cable 6 is released from the drum, and the bird repeller body 2 descends smoothly along one side of the lifting frame 3 under its own weight. Conversely, when the bird repeller body 2 needs to be reset after maintenance, the winch 7 is started to perform the cable reeling operation. The traction force of the winch 7 is transmitted through the cable 6, passing around the guide wheel 5, and lifting the bird repeller body 2 upward, causing it to rise along the lifting frame 3 to the working height. During this force transmission process, the guide wheel 5 converts the horizontal or oblique traction force from the bottom of the winch 7 into a vertical lifting force on the bird repeller body 2, while avoiding direct friction and cutting between the cable 6 and the top frame of the lifting frame 3, thus ensuring the service life and transmission stability of the cable 6. Through this architecture, the core pain point of traditional bird repellers being fixed at high altitudes, requiring operators to climb the tower for close-range maintenance, is completely solved. The risk of falling from heights is transformed into safe ground operation, significantly improving the convenience of maintenance and personal safety.

[0035] Example 2:

[0036] This embodiment, based on the basic lifting structure of the bird deterrent device for iron towers provided in Embodiment 1, further refines the design of the installation and fixing method of the guide wheel 5 on the partition plate 4. Specifically, the top of the partition plate 4 has a notch structure, and the guide wheel 5 is fixed within the notch structure.

[0037] The notch structure provides three-dimensional spatial constraints and hardware binding for the guide wheel 5. For example, the notch structure can be constructed as a U-shaped, V-shaped, or semi-circular groove. It should be understood that while a U-shaped groove is preferred in this embodiment to obtain a larger bottom support area, in other embodiments, a V-shaped groove can provide a more precise self-centering effect, and a semi-circular groove has the best surface fit with the cylindrical shaft, as long as it can form a partial structure that provides lateral stop and accommodates the guide wheel 5. The shaft or base of the guide wheel 5 is directly embedded and seated inside the notch structure, with the side walls on both sides of the notch and the bottom wall together forming a limiting space.

[0038] This embodiment uses a notch structure, the core mechanism of which is to achieve anti-displacement and anti-detachment by utilizing the interlocking of physical morphology. In contrast, if the top of the partition 4 is just a flat plane, and the guide wheel 5 is only connected by bolts and other fasteners for planar compression, under the conditions of long-term strong wind vibration of the tower and the alternating traction load generated by the repeated winding and unwinding of the cable 6 by the winch 7, the bolts at the planar connection are very likely to loosen due to micro-friction, which will lead to uncontrollable slippage or even detachment of the guide wheel 5 along the plane. Once the guide wheel 5 deviates, the routing path of the cable 6 will change accordingly, and the originally stable transmission topology will be destroyed. This will not only aggravate the friction and cutting between the cable 6 and the frame of the lifting frame 3, but may also cause serious interference risk of the bird deterrent body 2 getting stuck during lifting. The notch structure's sidewalls provide rigid stop and limit for the guide wheel 5. Even under severe vibration and stress conditions, the base or shaft of the guide wheel 5 is firmly held in place by the notch structure, fundamentally eliminating the possibility of slippage along the plane and ensuring the absolute stability of the guide wheel 5's installation position and the long-term constancy of the cable 6's transmission path. Therefore, the notch structure is not simply a matter of installation location selection, but rather a necessary and superior structural defense established to meet the requirements of anti-interference and anti-loosening under harsh tower conditions.

[0039] As another optional implementation, after the guide wheel 5 is embedded in the notch structure, it can also be supplemented with auxiliary locking components such as pins, snap rings or pressure plates that penetrate or press against the notch to form a double anti-detachment safety, further adapting to the tower installation needs in areas with extreme winds.

[0040] Example 3:

[0041] Based on the basic lifting structure of the iron tower bird deterrent provided in Example 1, this embodiment further refines the guiding and anti-swaying mechanism and the power anti-interference layout of the bird deterrent body 2 inside the lifting frame 3.

[0042] Specifically, the lifting frame 3 is symmetrically provided with vertical rods 8, and a sliding collar 9 is movably sleeved on the vertical rods 8. The sliding collar 9 is fixedly connected to the bird deterrent body 2.

[0043] The vertical rod 8, serving as a rigid track column within the lifting frame 3, typically extends parallel to the vertical direction. Its cross-section can be circular, square, or other polygonal, as long as it provides a stable sliding constraint surface for the sliding collar 9. The inner hole of the sliding collar 9 is adapted to the cross-sectional shape of the vertical rod 8, allowing the sliding collar 9 to slide smoothly up and down along the vertical rod 8 like a piston ring. When the winch 7 pulls the bird deterrent body 2 up and down via the cable 6, the engagement between the sliding collar 9 and the vertical rod 8 provides a rigid lateral limit stop for the bird deterrent body 2, fundamentally constraining its lateral swaying and tilting tendencies during the lifting process, ensuring that it always travels along a predetermined vertical trajectory.

[0044] Furthermore, a sleeve 10 is connected to one side of the bird deterrent body 2, the sleeve 10 is sleeved on the cable 6, and the sleeve 10 is connected to the sliding collar 9.

[0045] The sleeve 10 acts as a mechanical hub here. On the one hand, the hollow cavity of the sleeve 10 movably houses the cable 6, confining it within the local space of the sleeve 10 during retraction and extension, preventing the cable 6 from swinging erratically inside the large lifting frame 3. On the other hand, the outer wall of the sleeve 10 is fixedly connected to the sliding collar 9. This convergence structure allows the traction force transmitted by the cable 6 to be stably and directly transferred to the sliding collar 9 through the sleeve 10, thereby driving the bird deterrent body 2 to rise and fall synchronously. It should be understood that the connection between the sleeve 10 and the sliding collar 9 can be achieved through various methods such as integral molding, welding, or riveting with intermediate fasteners, as long as the rigidity of the traction force transmission can be ensured.

[0046] More importantly, the vertical rod 8 and the winch 7 are respectively located on both sides of the partition 4.

[0047] This spatial layout is not arbitrary, but a necessary choice based on the principle of preventing interference. The partition 4 extends along the interior of the lifting frame 3, effectively physically separating the inner cavity of the lifting frame 3 into two relatively independent functional areas: one side is the sliding guide area containing the vertical rod 8 and the sliding collar 9, and the other side is the power area containing the winch 7 and the cable 6 winding / unwinding area. When the winch 7 performs the winding / unwinding operation, the cable 6 will swing laterally and be rapidly pulled on the drum. Without physical isolation, this disorderly swinging cable is very likely to hook and entangle with the sliding collar 9 or the vertical rod 8, causing serious mechanical interference or even jamming. The physical barrier 4 fundamentally cuts off this interference path, allowing the guide area and the power area to operate independently without interfering with each other, greatly improving the system's operational reliability under long-term, frequent lifting conditions.

[0048] In addition, the sleeve 10, connecting rod 12 and sliding collar 9 are respectively arranged.

[0049] The "corresponding arrangement" referred to here means that, in terms of spatial geometry, the sleeve 10, connecting rod 12, and sliding collar 9 are arranged collinearly or coplanarly. For example, the connecting rod 12, as the intermediate force transmission arm connecting the sleeve 10 and the sliding collar 9, can have its axis coincide with the force center line of the sleeve 10 and the sliding center line of the sliding collar 9 in the same vertical plane. This geometrically symmetrical design ensures that when the cable 6 transmits traction force through the sleeve 10, the tension can reach the sliding collar 9 directly along the axis of the connecting rod 12 without eccentricity, avoiding torsional torque caused by the force point deviating from the sliding center. Without this corresponding arrangement, the eccentric traction force would force the sliding collar 9 to be skewed and squeezed on the vertical rod 8, exacerbating local wear and potentially causing jamming. Therefore, the corresponding arrangement is a necessary geometric constraint to ensure the smoothness of force transmission and extend the service life of the guide structure.

[0050] Example 4:

[0051] Based on the internal guidance and power interference prevention architecture provided in Embodiment 3, this embodiment further refines the microscopic anti-detachment mechanism of the connection between the bird deterrent body 2 and the lifting frame 3. Through multiple structural layers, a defense depth is constructed to ensure the absolute reliability of the lifting connection.

[0052] Specifically, the sleeve 10 is symmetrically fitted with a sleeve plate 11, which is disposed on the outer side of the bird repeller body 2.

[0053] The sleeve plate 11 is typically made of high-strength metal sheet through bending or casting. It is attached and fixed to the side wall of the outer shell of the bird repeller body 2 by conventional fastening methods such as welding, bolting, or riveting. It should be understood that although this embodiment preferably uses two sleeve plates 11 symmetrically to achieve the best mechanical balance, in lightweight bird repeller models with less stress, only a single sleeve plate 11 or multiple sleeve plates 11 arranged in a ring can be used, as long as they can provide sufficient connection anchor points. The introduction of the sleeve plate 11 essentially adds a large-area transition force transmission panel between the sleeve 10 and the bird repeller body 2. Since the outer shell of the bird repeller body 2 is often made of relatively thin sheet metal or plastic material, if the sleeve 10 is directly connected to the outer shell in a point-like manner, after long-term exposure to the repeated lifting and alternating loads of the winch 7, the connection point is very prone to stress concentration, resulting in shell tearing or local dent deformation. By increasing the contact area with the bird deterrent body 2, the sleeve 11 disperses the originally concentrated point force into a surface force, which significantly enhances the structural strength and fatigue life of the connection.

[0054] Furthermore, a connecting rod 12 is provided between the sleeve 10 and the sliding collar 9, and the connecting rod 12 is disposed between the sleeve plates 11.

[0055] The connecting rod 12 serves as the intermediate force transmission arm, with its two ends rigidly connected to the outer wall of the sleeve 10 and the side of the sliding collar 9, respectively, for example, by hinged pins or integral welding. The connecting rod 12 is cleverly arranged in the gap between the two sleeve plates 11. This space utilization not only makes the structure more compact and avoids additional space occupation of the lifting frame 3, but also makes the connecting rod 12, sleeve plates 11 and sleeve 10 form a rigid frame system similar to a truss. When the cable 6 applies traction force through the sleeve 10, the connecting rod 12 can directly and rigidly transmit part of the tension to the sliding collar 9, avoiding the bending deflection that may occur when the sleeve 10 is subjected to force alone, thereby enhancing the rigidity of the overall force transmission mechanism and ensuring that the bird deterrent body 2 does not experience microscopic elastic deformation accumulation when subjected to lifting force.

[0056] More importantly, a slider 13 is provided between the sleeve plate 11 and the bird deterrent body 2. The slider 13 has an I-shaped structure and is installed through the lifting frame 3.

[0057] The slider 13 is the core component that enables physical anti-detachment locking between the bird deterrent body 2 and the lifting frame 3. The I-shaped structure means that the slider 13 has a wider top wing plate, a narrower middle web plate, and a wider bottom wing plate. In the installed state, the middle web plate of the slider 13 moves through the vertical long slot opened on the side wall of the lifting frame 3, while the top and bottom wing plates are respectively locked onto the inner and outer sides of the side wall of the lifting frame 3. This embodiment, by setting the I-shaped slider 13, utilizes the geometric shape of the wing plates to form a three-dimensional interlocking anti-detachment constraint. In contrast, if only a simple straight rod or rectangular cross-section slider is used to pass through the slot of the lifting frame 3, although it can provide lifting guidance, under the strong wind lateral thrust conditions faced by the tower in actual operation, the bird deterrent body 2 is very likely to tilt outward away from the lifting frame 3. At this time, the straight rod will shake within the slot or even detach laterally from the slot opening, causing the bird deterrent body 2 to fall off the lifting track and cause a serious safety accident. The two wings of the I-shaped slider 13 are firmly held in place on the inner and outer sides of the side wall. No matter what kind of lateral wind force or eccentric load the bird deterrent body 2 is subjected to, the slider 13 cannot be dislodged laterally from the slide groove and can only slide smoothly within the vertical slide groove. Therefore, the I-shaped structure is not an arbitrary choice of cross-section, but a necessary and optimal structural defense to ensure that the bird deterrent body 2 will never detach from the lifting frame 3 under any extreme working conditions.

[0058] As another optional implementation, wear-resistant and friction-reducing pads or rolling rollers can be provided between the wing plates of the I-shaped slider 13 and the inner and outer surfaces of the side wall of the lifting frame 3 to further reduce sliding friction resistance, improve the smoothness of lifting, and meet the application requirements of high-frequency maintenance lifting.

[0059] Example 5:

[0060] Based on the basic lifting structure of the bird deterrent device provided in Example 1, this embodiment further refines the external anti-sway mechanism of the bird deterrent device body 2, constructing an external rolling constraint defense line independent of the internal guiding structure.

[0061] Specifically, the bird deterrent body 2 is provided with an auxiliary wheel 14 on the side near the lifting frame 3, and the auxiliary wheel 14 is rolled on the outer side of the lifting frame 3.

[0062] The auxiliary wheel 14 is typically fixedly mounted on the back side of the bird repeller body 2, i.e., the side closest to the lifting frame 3, via a pivot assembly such as an axle, bracket, or bearing seat. It should be understood that although this embodiment and accompanying drawings show the auxiliary wheel 14 positioned in the upper region of the side of the bird repeller body 2, in other embodiments, to accommodate bird repeller bodies 2 with different center of gravity positions, the auxiliary wheel 14 can also be positioned in the middle or lower region of the side, as long as it can form a stable rolling contact with the outer surface of the lifting frame 3. In the installed state, the outer circumferential surface of the auxiliary wheel 14 directly abuts against the plane of the outer wall of the lifting frame 3. When the bird repeller body 2 moves up and down along the lifting frame 3, the auxiliary wheel 14 rolls against the outer surface of the lifting frame 3, rather than sliding.

[0063] This embodiment utilizes an external auxiliary wheel 14, the core mechanism of which lies in using a rolling fulcrum to resist outward tilting moment and eliminate swaying and jamming. In actual tower operation, the bird deterrent body 2 is suspended on one side of the lifting frame 3, and its center of gravity often deviates from the central axis of the lifting frame 3. Furthermore, the high-altitude environment inevitably subjectes it to the thrust of strong crosswinds, making the bird deterrent body 2 prone to outward tilting away from the lifting frame 3. Without external constraints, this outward tilting tendency will force the connection between the bird deterrent body 2 and the lifting frame 3 to experience unilateral pressure, significantly increasing sliding friction resistance and causing lifting jamming. Long-term operation will also cause severe wear and even deformation of the connection structure. The auxiliary wheel 14 provides a rigid and low-friction rolling fulcrum on the outer surface of the lifting frame 3. When the bird repeller body 2 is subjected to wind force or a shift in the center of gravity, causing it to tilt outwards, the auxiliary wheel 14 first abuts against the outer side of the lifting frame 3, transforming the lateral swaying force that could have caused sliding and squeezing into a rolling constraint force. This ensures that the bird repeller body 2 is always confined within a predetermined parallel trajectory during the lifting process, completely eliminating swaying and jamming. More importantly, this rolling constraint of the external auxiliary wheel 14, together with the guiding constraint of the sliding collar 9 inside the lifting frame 3 along the vertical rod 8, forms a combined internal and external anti-deviation system. The internal sleeve structure provides lateral restraint, while the external auxiliary wheel 14 provides a reverse rolling fulcrum. The two, one inside and one outside, jointly clamp and constrain the bird repeller body 2, ensuring absolute stability of the lifting movement.

[0064] Furthermore, from a practical perspective of patent protection and infringement enforcement, the auxiliary wheel 14, as an externally visible feature, offers significant advantages in evidence collection. Since the auxiliary wheel 14 is installed on the outer side of the bird deterrent device body 2 and adheres to the outer wall of the lifting frame 3, it is completely exposed on the device's external outline. Its existence and position can be directly confirmed through visual observation or photography without disassembling the outer shell or internal partitions of the lifting frame 3. This high visibility allows staff to easily and directly obtain structural evidence of the auxiliary wheel 14 from below the tower or through drone inspections in the event of potential infringement, greatly reducing the difficulty and cost of infringement evidence collection and building a more robust and easily enforceable external feature defense for the rights holder.

[0065] As another optional implementation, the number of auxiliary wheels 14 can be flexibly adjusted according to the size and weight of the bird repeller body 2. For example, one auxiliary wheel 14 can be set at each of the upper and lower ends of the bird repeller body 2 to form a double-support anti-deviation point, or multiple auxiliary wheels 14 can be arranged in a matrix on the side of the heavy bird repeller body 2 to distribute lateral forces. At the same time, the outer circumference of the auxiliary wheels 14 can also be covered with a layer of wear-resistant and shock-absorbing material such as rubber or polyurethane to further reduce rolling noise and adapt to the surface roughness that may exist on the outer wall of the lifting frame 3, thereby improving the smoothness of rolling and the service life.

[0066] Example 6:

[0067] To more intuitively demonstrate the decisive role and commercial value of the above-mentioned structural features of this invention in actual operation and maintenance environments, the following is a detailed explanation of the ground safety maintenance operation closed loop of the entire technical solution, using a typical scenario of an ultrasonic module failure in a bird deterrent device on a high-voltage tower as an example.

[0068] The scenario is as follows: The ultrasonic generator module inside the bird deterrent device 2, located high up on a high-voltage power tower, has malfunctioned due to prolonged exposure to the harsh outdoor environment. Birds are beginning to gather again at the tower's crossarm, posing a serious risk of short circuits. Traditionally, maintenance personnel must carry heavy tools to the top of the tower, tens of meters high, for close-range repairs—a process that is extremely time-consuming and carries a high risk of fall. However, using the bird deterrent device provided by this invention, the entire maintenance process is transformed into an efficient and absolutely safe ground-based operation.

[0069] The specific operation sequence is as follows:

[0070] Step S100, Fault Confirmation and Preparation. Personnel on the ground confirm the fault status of the bird deterrent device body 2 using an inspection drone or remote monitoring terminal, and then proceed to a location near the base 1 below the tower. It should be understood that although this embodiment uses an ultrasonic module fault as an example, in other application scenarios, the faulty object can be any component requiring close-range replacement or repair, such as a voice playback module, flash assembly, or power supply battery; the lifting and maintenance mechanism of this invention is applicable to all of these.

[0071] Step S200: Ground-controlled descent. Workers in a low-lying, safe area activate winch 7 to perform the line-laying operation.

[0072] The drum of the winch 7 rotates to release the cable 6. The cable 6 releases traction downward through the guide wheel 5 at the top of the partition 4. Under its own weight, the bird deterrent body 2 begins to descend smoothly along one side of the lifting frame 3.

[0073] During this descent, the internal and external dual anti-deviation structure and isolation layout constructed in the aforementioned embodiments play a crucial synergistic role in ensuring safety. Internally, the sliding collar 9 provides rigid sliding guidance along the vertical rod 8, fundamentally constraining the lateral swaying of the bird deterrent body 2 during descent. Externally, the auxiliary wheel 14 rolls tightly against the outer surface of the lifting frame 3, transforming the outward tilting tendency that may be caused by high-altitude crosswinds into a low-friction rolling fulcrum constraint, completely eliminating swaying and jamming phenomena.

[0074] Meanwhile, the partition 4 physically isolates the sliding guide area where the vertical rod 8 is located from the winding area where the winch 7 is located, ensuring that the cable 6 will never hook, entangle or interfere with the sliding collar 9 or the vertical rod 8 when it is quickly released and pulled, thus ensuring the absolute smoothness and safety of the descent action.

[0075] The bird deterrent device 2 eventually landed smoothly at a low stopping position near the base 1, which was completely within the safe working range that the staff could reach without having to climb.

[0076] Step S300, Ground Safety Inspection. Workers operate the bird deterrent device body 2, which is positioned low on the ground, directly from the ground. They open the casing, quickly remove the malfunctioning ultrasonic generator module, and replace it with a brand new spare. Throughout the entire inspection process, the worker's feet remain on the ground, eliminating the need for fall protection harnesses. The operating space is spacious, and tools are easily accessible, reducing what could have been a dangerous high-altitude operation taking several hours to a routine ground maintenance session of just over ten minutes.

[0077] Step S400: Re-elevate and reset. After inspection and confirmation, the operator reverses the start of winch 7 to perform the cable reeling operation. The traction force of winch 7, through cable 6, passes over guide wheel 5 and lifts bird deterrent body 2 upward. Under the dual clamping protection of the sliding collar 9 and the internal guide of vertical rod 8, and the outer rolling constraint of auxiliary wheel 14, bird deterrent body 2 rises smoothly and without swaying along lifting frame 3 until it returns to the high working position at the top of lifting frame 3, restoring the bird deterrent function.

[0078] The complete operational loop described above clearly demonstrates that this invention, through the power topology design of the winch 7 and cable 6, combined with the internal anti-deviation system consisting of the vertical rod 8 and sliding collar 9, the external rolling constraint system consisting of the auxiliary wheel 14, and the anti-interference isolation layout consisting of the partition 4, not only fundamentally eliminates the risk of falls during high-altitude maintenance but also ensures the operational stability and structural reliability of the equipment under frequent lifting and lowering maintenance conditions. These structural features are not isolated functional additions but collectively constitute the essential technological foundation supporting the core commercial value of "ground-based safe maintenance."
