Description

Technical Field

[0001] This utility model relates to the field of bird protection technology, and in particular to a bird protection device for power transmission lines. Background Technology

[0002] Bird protection devices for power transmission lines refer to a series of equipment or facilities specifically designed and installed to prevent birds from damaging power transmission lines. Through various means, such as physical blocking, driving away, and frightening, these devices prevent birds from roosting or nesting on power transmission line towers, prevent bird droppings from contaminating insulators, and prevent birds from short-circuiting the lines. This ensures the safe and stable operation of power transmission lines, reduces power outages and equipment damage caused by bird activity, and ensures the reliability and continuity of power supply.

[0003] A search revealed Chinese patent publication number CN210987900U, which discloses a laser-based bird-repelling analysis and protection device for power transmission lines in the field based on ecological big data. The device includes a sleeve, with a protective cover bolted to the top of the sleeve. A top seat is bolted to the top of the protective cover, and a support column is rotatably connected to the center of the top of the top seat via a pivot. A buzzer is rotatably connected to the top of the support column via a pivot. This device collects sounds generated near the power transmission line using a retractable sound sensor placed on the line. After comparing the sounds with ecological big data, it determines whether the sounds are birds and activates the buzzer and laser emitter to scare them away. This avoids the problem of birds developing adaptation due to prolonged use of the buzzer and laser emitter, providing sufficient stimulation to improve the bird-repelling effect. However, its effectiveness is greatly affected by environmental noise, and birds may develop adaptation after long-term use. Furthermore, it generally suffers from poor sustainability and complex installation. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a bird protection device for power transmission lines, which aims to improve the problem of birds adapting after long-term use in the existing technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a bird-proof protection device for power transmission lines, comprising a cable, a lower clamping body at the bottom of the cable, an upper clamping body at the top of the lower clamping body, motors on both the front and rear sides of the top wall of the upper clamping body, a crank fixedly connected to the output end of the motor, a connecting plate rotatably connected to the left side of the outer wall of the crank, a rotating shaft fixedly connected to the left ends of the outer walls of the two connecting plates on opposite sides, a slider rotatably connected to the outer wall of the rotating shaft, guide rails fixedly connected to both the front and rear sides of the top wall of the upper clamping body, the slider slidingly connected to the guide rails, a beater fixedly connected to the outer walls of the two sliders on opposite sides, a protective net installed on the top wall of the upper clamping body, and a fixing mechanism provided on the outer wall of the cable for fixing the two clamping bodies and the cable.

[0006] The above technical solution involves indirectly starting a motor, which drives a crank to rotate. The rotation of the crank then drives the connecting plate to rotate, which in turn causes the slider on the rotating shaft to slide on the guide rail. The movement of the slider causes the clapper to extend and retract, causing the clapper to strike the protective net and generate vibration. The vibration can drive away birds that approach, effectively preventing birds from staying or nesting near the power transmission line, thereby protecting the power transmission line from potential bird damage. The outer wall of the cable is equipped with a fixing mechanism, which is used to fix the two clamps and the cable.

[0007] As a further description of the above technical solution:

[0008] The fixing mechanism includes a connecting block, which is fixedly connected to the rear side of the outer wall of the lower clamping body. A connecting shaft is fixedly connected to the rear side of the outer wall of the upper clamping body. The connecting shaft is rotatably connected to the connecting block. Multiple square grooves are equally spaced on the bottom wall of the lower clamping body and the top wall of the upper clamping body. A spring is fixedly connected to the inner wall of the square groove. A clamping block is fixedly connected to the end of the spring. The clamping block is slidably connected to the square groove. Bolts are threadedly connected to the left and right ends of the front side of the top wall of the lower clamping body and the upper clamping body.

[0009] The above technical solution involves placing the cable between the upper and lower clamps, rotating the upper clamp so that the connecting shaft at the rear of the upper clamp rotates within the connecting shaft at the rear of the lower clamp. When the upper and lower clamps are closed, the spring in the square groove pushes the clamping block to move towards the cable, thereby applying clamping force to the cable from multiple directions. This ensures that the cable is securely fixed between the upper and lower clamps, preventing displacement or shaking due to wind and vibration during operation. Tightening the bolts further strengthens the tight fit between the upper and lower clamps, enhancing the cable's fixation effect. Disassembly can be easily achieved by simply rotating the bolts, without the need for complex tools or specialized skills.

[0010] As a further description of the above technical solution:

[0011] A fixing block is fixedly connected to the bottom wall of the motor, and the fixing block is fixedly connected to the front and rear sides of the top wall of the upper clamp.

[0012] Through the above technical solution, the fixing block plays the role of connecting and supporting the motor, ensuring that the motor can be stably installed on the upper clamp.

[0013] As a further description of the above technical solution:

[0014] The top wall of the upper clamp is fixedly connected to baffles on both the left and right sides.

[0015] The above technical solution uses a baffle to prevent external objects from colliding with or interfering with other components of the device from the side.

[0016] As a further description of the above technical solution:

[0017] Both the lower clamp and the upper clamp have multiple heat dissipation holes spaced at equal intervals on their outer walls.

[0018] The above technical solution uses heat dissipation holes to increase air circulation, prevent the internal temperature of the cable from becoming too high when transmitting current, extend the service life of the device, and reduce the risk of failure due to overheating.

[0019] As a further description of the above technical solution:

[0020] The outer wall of the clamping block is fitted with an insulating rubber pad.

[0021] Insulating rubber mats are used to provide insulation and protection.

[0022] As a further description of the above technical solution:

[0023] The front side of the top wall of the lower clamp is provided with a slot, and a rubber pad is provided inside the slot, and the slot engages with the rubber pad.

[0024] The above technical solution uses a slot to fix a rubber pad, which in turn provides a stable fixation.

[0025] As a further description of the above technical solution:

[0026] A washer is provided on the upper middle part of the outer wall of the bolt.

[0027] The above technical solution uses gaskets to prevent bolts from loosening due to vibration after tightening, thus enhancing stability and reliability.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, an indirect starting motor drives the crank and connecting plate to rotate, thereby causing the slider to slide on the guide rail. The clapper extends and retracts to vibrate the protective net, which enhances the bird-repelling effect through intermittent vibration without harming the birds. This prevents birds from staying or nesting near the power transmission line, thus protecting the power transmission line from bird damage. The protective effect is long-lasting and not easily adapted to by birds.

[0030] 2. In this utility model, the cable is placed between the upper clamp and the lower clamp. The upper clamp is rotated, and the connecting shaft behind the upper clamp rotates in the connecting block behind the lower clamp to achieve closure. The spring in the square groove pushes the clamp block to clamp the cable to prevent it from shifting due to external force. The bolt is tightened to strengthen the fixation. Disassembly only requires rotating the bolt, without the need for complicated tools and professional skills. Attached Figure Description

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 2 , Figure 3 and Figure 4 This utility model provides an embodiment of a bird-proof protection device for power transmission lines, comprising a cable 1, a lower clamp 3 at the bottom of the cable 1, an upper clamp 4 at the top of the lower clamp 3, motors 5 on the front and rear sides of the top wall of the upper clamp 4, cranks 6 fixedly connected to the output end of the motors 5, the motors 5 driving the cranks 6 to rotate, connecting plates 7 rotatably connected to the left side of the outer wall of the cranks 6, the cranks 6 driving the connecting plates 7 to rotate, rotating shafts 8 fixedly connected to the left ends of the outer walls of the two connecting plates 7 on opposite sides, sliders 9 rotatably connected to the outer walls of the rotating shafts 8, guide rails 10 fixedly connected to the front and rear sides of the top wall of the upper clamp 4, sliders 9 slidably connected to the guide rails 10, the connecting plates 7 driving the sliders 9 on the rotating shafts 8 to slide on the guide rails 10, the outer ends of the two sliders 9... A clapper 11 is fixedly connected to the side of the wall away from the wall. The slider 9 drives the clapper 11 to extend and retract. A protective net 12 is installed on the top wall of the upper clamp 4. The protective net 12 is used to prevent birds from falling directly onto the cable 1 or other parts of the device from above, and plays a physical blocking role. A fixing mechanism 2 is set on the outer wall of the cable 1. The fixing mechanism 2 is used to fix the two clamps and the cable 1. A fixing block 13 is fixedly connected to the bottom wall of the motor 5. The fixing block 13 is fixedly connected to the front and rear sides of the top wall of the upper clamp 4. The fixing block 13 plays a role in connecting and supporting the motor 5, ensuring that the motor 5 can be stably installed on the upper clamp 4. Baffles 14 are fixedly connected to the left and right sides of the top wall of the upper clamp 4. The baffles 14 are used to prevent external objects from colliding with or interfering with other parts of the device from the side.

[0040] Specifically, the motor 5 is indirectly started, which drives the crank 6 to rotate. The rotation of the crank 6 in turn drives the connecting plate 7 to rotate. The connecting plate 7 then causes the slider 9 on the rotating shaft 8 to slide on the guide rail 10. The movement of the slider 9 causes the beater 11 to extend and retract, so that the beater 11 strikes the protective net 12 and generates vibration. The vibration can drive away birds that approach, effectively preventing birds from staying or nesting near the power transmission line, thereby protecting the power transmission line from the potential impact of bird damage. The outer wall of the cable 1 is provided with a fixing mechanism 2, which is used to fix the two clamps and the cable 1. The fixing block 13 plays the role of connecting and supporting the motor 5, ensuring that the motor 5 can be stably installed on the upper clamp 4. The baffle 14 is used to prevent external objects from colliding with or interfering with other parts of the device from the side.

[0041] Reference Figure 3 and Figure 5 The fixing mechanism 2 includes a connecting block 201, which is fixedly connected to the rear side of the outer wall of the lower clamping body 3. A connecting shaft 202 is fixedly connected to the rear side of the outer wall of the upper clamping body 4. The connecting shaft 202 is rotatably connected to the connecting block 201, and the connecting shaft 202 rotates within the connecting shaft 202. Multiple square grooves 203 are equally spaced on the bottom wall of the lower clamping body 3 and the top wall of the upper clamping body 4. A spring 204 is fixedly connected to the inner wall of the square groove 203, and a clamping block 205 is fixedly connected to the end of the spring 204. The clamping block 205 is slidably connected to the square groove 203, and the spring 204 in the square groove 203 will push the clamping block 205 towards the... The direction of cable 1 is moved, thereby applying clamping force to cable 1 from multiple directions to ensure that cable 1 is firmly fixed between the upper clamp 4 and the lower clamp 3. The left and right ends of the front side of the top wall of the lower clamp 3 and the upper clamp 4 are threaded with bolts 206. Bolts 206 are used to strengthen the tight fit between the upper clamp 4 and the lower clamp 3. An insulating rubber pad 16 is installed on the outer wall of the clamping block 205. The insulating rubber pad 16 is used to provide insulation and protection. A washer 19 is provided in the upper middle part of the outer wall of the bolt 206. The washer 19 is used to prevent the bolt 206 from loosening due to vibration after tightening, thereby enhancing stability and reliability.

[0042] Specifically, cable 1 is placed between upper clamp 4 and lower clamp 3. The upper clamp 4 is rotated so that the connecting shaft 202 on the rear side of the upper clamp 4 rotates within the connecting shaft 202 on the rear side of the lower clamp 3. When the upper clamp 4 and lower clamp 3 are closed, the spring 204 in the square groove 203 pushes the clamping block 205 toward the direction of cable 1, thereby applying clamping force to cable 1 from multiple directions. This ensures that cable 1 is firmly fixed between the upper clamp 4 and lower clamp 3, preventing displacement or shaking due to wind and vibration during operation. Finally, by tightening the bolt 206, the tight fit between the upper clamp 4 and lower clamp 3 is further strengthened to enhance the fixing effect on cable 1. The installation is simple, and it can be easily disassembled by simply rotating the bolt 206. No complicated tools or professional skills are required. The insulating pad 16 is used for insulation and protection, and the gasket 19 is used to prevent the bolt 206 from loosening due to vibration after tightening, thus enhancing stability and reliability.

[0043] Reference Figure 1 and Figure 5 The outer walls of both the lower clamp 3 and the upper clamp 4 are provided with multiple heat dissipation holes 15 at equal intervals. The heat dissipation holes 15 are used to increase air circulation, prevent the internal temperature of the cable 1 from getting too high when transmitting current, extend the service life of the device, and reduce the risk of failure due to overheating. The front side of the top wall of the lower clamp 3 is provided with a slot 17. The slot 17 is used to fix the rubber pad 18. The rubber pad 18 is provided inside the slot 17. The slot 17 and the rubber pad 18 are engaged. The rubber pad 18 is used to stabilize and fix the device.

[0044] Specifically, the heat dissipation hole 15 is used to increase air circulation, prevent the internal temperature of the cable 1 from getting too high when transmitting current, extend the service life of the device, and reduce the risk of failure due to overheating. The slot 17 is used to fix the rubber pad 18, which is used to stabilize and fix the device.

[0045] Working principle: The motor 5 is started indirectly. The motor 5 drives the crank 6 to rotate. The crank 6 drives the connecting plate 7 to rotate. The connecting plate 7 drives the slider 9 on the rotating shaft 8 to slide on the guide rail 10. The slider 9 drives the flap 11 to extend and retract, so that the flap 11 beats the protective net 12 to make it vibrate, which can drive away birds that approach and prevent them from approaching the power transmission line. Thus, it can drive away birds and prevent birds from staying or nesting near the power transmission line, thus protecting the power transmission line from bird damage.

[0046] The cable 1 is placed between the upper clamp 4 and the lower clamp 3. The upper clamp 4 is rotated, and the connecting shaft 202 on the rear side of the upper clamp 4 rotates within the connecting shaft 202 on the rear side of the lower clamp 3. When the upper clamp 4 and the lower clamp 3 are closed, the spring 204 in the square groove 203 pushes the clamping block 205 to move towards the cable 1, applying clamping force to the cable 1 from multiple directions to ensure that the cable 1 is stably fixed between the upper clamp 4 and the lower clamp 3, preventing the cable 1 from shifting or shaking due to wind and vibration during operation. Finally, by tightening the bolt 206, the upper clamp 4 and the lower clamp 3 are further tightened to enhance the fixing effect on the cable 1. The installation is simple, and disassembly can be performed by simply turning the bolt 206 without complicated tools or professional skills.
