Description

Technical Field

[0001] The present invention relates to a bird-proofing device for a power transmission line, which is specifically intended to be installed on a crossarm above an insulator of a live line to prevent birds from fighting, resting, nesting, and other phenomena that could affect line reliability. Background Art

[0002] As people's awareness of environmental protection increases, the natural environment is gradually improving, and bird activities are becoming more frequent. The number of insulation short-circuit tripping faults caused by birds nesting, defecating, and fighting directly above the insulators on high-voltage transmission lines has increased significantly. At present, in order to prevent bird activities from causing insulation short-circuit faults on high-voltage transmission lines, various bird-proofing components are installed on the towers to prevent bird damage. Among the bird-proofing components, the use of bird spikes and windmill-type bird repellers is already existing technology. They are installed as auxiliary facilities at the end of the crossarms of the transmission line towers, which can effectively prevent birds from fighting, staying, and nesting directly above the conductors and insulator strings, ensuring the smooth flow of the line and reducing the occurrence of bird-damaged tripping accidents. However, due to their own design, installation location, installation quantity, and the design of the tower materials at the installation site, the existing bird spikes and windmill-type bird repellers inevitably have loopholes in the prevention space, allowing birds to stay, defecate, and nest in the loopholes, seriously threatening the safe and stable operation of the transmission line.

[0003] In addition, to save space, existing transmission lines often use multiple circuits on the same tower (commonly double-circuit lines on the same tower) for corridor construction. During line maintenance, multiple circuits on the same tower are shut down in rotation (multiple lines installed on the same tower, one line is powered off, and the others are energized). The risk of maintenance personnel accidentally entering the crossarm of a live line after climbing the tower increases significantly, posing a serious threat to the safety of maintenance personnel. Bird-proofing spikes and windmill-type bird repellers, as ancillary facilities installed at the farthest end of the tower crossarm and closest to the conductors (as shown in Figure 2), can fully utilize the location advantage of bird-proofing devices. An integrated sound and light bird-proofing device with a warning function to prevent accidental entry into the crossarm of a live line has been invented. This device addresses the shortcomings of existing bird-proofing devices and the installation of multiple circuits on the same tower, achieving "one device, multiple functions" for bird damage prevention, external damage prevention, and electric shock warning, thereby improving the inherent safety level of the line.

[0004] At present, in order to prevent bird damage accidents on high-voltage transmission lines, bird-proof spikes and windmill-type bird repellers are generally installed at the end positions of the cross arms of line towers.

[0005] Bird-proof spikes are installed on the crossarms directly above the insulators of high-voltage transmission lines. These spikes weave a protective net covering a certain area, preventing birds from landing, lingering, or nesting, thereby preventing bird damage. Windmill-style bird repellers use natural wind as their power source, using wind to move the bowl-shaped blades, which in turn rotate the reflective mirrors within the blades, continuously emitting intermittent reflected light to repel birds.

[0006] After bird spikes are installed, due to the location, number of spikes, and the design of the tower material where they are installed, gaps can easily form between the spikes, allowing birds to nest. Furthermore, these bird spikes do not prevent external damage at night, and they do not provide a warning to maintenance personnel entering the live crossarm.

[0007] Windmill-type bird repellents are less effective at night when there's no light, leaving a larger loophole in the defense space. Furthermore, these bird repellents lack nighttime protection from external damage, and they also lack the warning function to prevent maintenance personnel from accidentally entering the live crossarm. Summary of the Invention

DETAILED DESCRIPTION

[0040] The specific implementation of the present invention is described below with reference to the accompanying drawings and embodiments:

[0041] like Figure 1-1 、 1-2, 2-1, 2-2, 3 to 6, which show a specific embodiment of the present invention. As shown in the figure, the sound and light integrated bird-proofing device with the warning function of preventing accidental entry into the live line cross arm disclosed by the present invention comprises a bird-proofing component 11 installed on the cross arm, and the bottom of the bird-proofing component 11 is connected to the packaging box through the assembly part 9; the bird-proofing component 11 is installed on the cross arm through the bracket component; the present invention is a retrofit structure, which is installed on the existing bird-proofing component to improve and expand the bird-proofing function, and the same space occupies a more complete bird-proofing function and more extended functions (anti-accidental entry).

[0042] The packaging box is a transparent cylindrical structure, and an independent flashing light circuit and a warning circuit are set inside the packaging box; the cylindrical structure is for easy installation, and at the same time, the flashing light and the infrared sensor light are distributed more evenly, effectively avoiding the generation of blind spots;

[0043] The top surface of the packaging box is connected to the flashing light circuit photovoltaic panel 101 and the early warning circuit photovoltaic panel 205 for supplying power to the flashing light circuit and the early warning circuit;

[0044] The early warning circuit comprises a plurality of infrared sensing contacts 4 evenly arranged on the side of the packaging box;

[0045] The flashing light circuit comprises a flashing light circuit energy storage battery 102, a photosensitive switch 104 and an LED flashing warning component 103 connected in series; the flashing light circuit photovoltaic panel used to power the flashing light circuit energy storage battery is a 120-degree fan-shaped photovoltaic panel;

[0046] The warning circuit comprises a proximity sensor switch 201, an alarm assembly 202, an infrared sensor switch 203, and a warning circuit energy storage battery 204 connected in series. Two warning circuit energy storage batteries 204 are provided, namely Battery I and Battery II. Corresponding photovoltaic panels 205 for powering the warning circuit are two 120-degree fan-shaped photovoltaic panels, I 211 and II 212, respectively, which are powered by Battery I 209 and Battery II 210. The present invention evenly divides the top surface of the package box by three fan-shaped photovoltaic panels, providing power to each panel separately, ensuring maximum solar energy absorption. Therefore, the present invention has broad adaptability and can be incorporated into any existing bird-repellent assembly with a hollow, light-transmitting structure, such as bird-repellent spikes and windmill-style bird repellents, thereby improving both bird-repellent functionality and preventing trespassing.

[0047] As a preferred embodiment of the present invention, Figure 5As shown: the packaging box is made of acrylic material, and the center of the packaging box is a hollow assembly hole 5 for threaded connection to the assembly part 9 of the bird-proof component 11; the flashing light circuit photovoltaic panel 101, photovoltaic panel I211 and photovoltaic panel II212 are clamped on the upper surface of the packaging box through a card slot; the area outside the upper surface of the packaging box is a red coating area 6; the inner wall of the packaging box is a diffuse reflection material. The packaging box disclosed in this embodiment is durable, and the photovoltaic panel is easy to assemble through the clamping structure; the diffuse reflection material allows the flashlight to radiate evenly, and the red coating area is the packaging box itself and the light passing through it all have a red light that birds are disgusted with, which plays a bird-repelling and warning function. The packaging can be made of corrosion-resistant, aging-resistant, and light-transmitting materials (to facilitate the normal operation of the solar panel and the propagation of the flashing light, such as Figure 5 The package box is a hollow, oblate cylindrical structure, with the diameter of the central hollow area matching the lower mounting point of the bird deterrent. Except for the top where the solar panel is mounted, the entire box is red. The inner walls feature a diffuse reflective design, ensuring that light reaches the entire perimeter of the bird deterrent. The box includes slots for securing the solar panels, batteries, circuit boards, and other components. The side walls are evenly perforated to accommodate infrared sensors, ensuring full infrared coverage on all sides of the bird deterrent.

[0048] The flashing light circuit and the warning circuit are independent circuits. The flashing light circuit is powered by a single 120° sector solar panel; the warning circuit is powered by two 120° sector solar panels. Both circuits are enclosed and secured in a housing made of highly transparent material. This allows the flashing light to penetrate the housing to fill the gaps in the bird barbs and windmill-style bird repellents, allowing them to work together to repel birds. Furthermore, the three solar panels are housed in a highly transparent housing to optimize light energy conversion. The warning circuit's infrared sensing contacts are evenly distributed around the housing, ensuring 360° coverage. The housing utilizes a hollow, oblate cylindrical structure, with the center hollow area equal in diameter to the lower end of the bird deterrent, facilitating its integration with the device.

[0049] As a preferred embodiment of the present invention, Figure 1-1 、 1-2 As shown: the flashing light circuit stores energy during the day and stays on at night; the flashing light circuit includes multiple groups of parallel-connected LED light-emitting diode units, each group of LED light-emitting diode units includes an LED, a capacitor, two resistors and a transistor.

[0050] As a preferred embodiment of the present invention, Figure 1-1 、 1-2As shown, the LED light-emitting diode units are arranged in three groups, and the flashing light circuit comprises an LED flashing warning circuit composed of LED lamp beads (LED1-LED3), capacitors (C1-C3), resistors (R1-R6), and transistors (Q1-Q3). This embodiment discloses a three-group LED flashing light structure, which can also be expanded. A three-group structure can achieve effective bird deterrence in a relatively economical manner.

[0051] The flashing light circuit is mainly composed of LED flashing warning components, photosensitive switches, energy storage batteries, solar panels, etc., as shown in Figure 1 (1). The circuit is powered by independent solar panels and batteries, and is connected in series with a photosensitive switch to ensure that the flashing light circuit is fully charged at night and is in a constant flashing state. The flashing light uses red flashing light to fill the loopholes in the original bird-proofing device at night to prevent birds from staying, defecating, and building nests in the loopholes at night. At the same time, the flashing light flashes all the time at night, and can also set off the shape and structure of the tower, and use dots and lines to outline the direction of the line, which serves as a warning to nighttime construction workers near the tower, and prevents the line tower from being damaged by external forces such as large machinery. Figure 1-1 and 1-2 Figure 2 shows the schematic design of the flashing light circuit. For ease of packaging, the solar panel adopts a 120° fan-shaped design. The cylindrical packaging box is designed to evenly mount the infrared sensor contacts around the perimeter, achieving 360° coverage. The solar panel is also designed to fit within the box, adopting a fan-shaped structure. The 120° fan-shaped structure increases the light-collecting surface, and is secured by a slot at the top of the packaging box. A photosensor is connected in series with the circuit to ensure the battery stores energy during the day and remains illuminated at night. The LED flashing warning circuit consists of a storage battery, LEDs (LED1-LED3), capacitors (C1-C3), resistors (R1-R6), and transistors (Q1-Q3). The number of LEDs can be increased depending on their brightness to ensure sufficient flashing light at night to scare away resident birds.

[0052] As a preferred embodiment of the present invention, Figure 2-1 、 2-2 As shown in the warning circuit, when the proximity sensor switch 201 and the infrared sensor switch 203 are both closed, the alarm component 202 issues a long alarm. When the proximity sensor switch 201 and the infrared sensor switch 203 are not both closed at the same time, the alarm component 202 issues a short alarm. The long alarm in this embodiment is a sharp, long-lasting chirp until the warning contact is detected; the short alarm is a sharp chirp that stops after two beeps. The two beeps have a basic bird deterrent effect and also serve as a warning to prevent trespassing, i.e., the circuit is not energized at this time.

[0053] As a preferred embodiment of the present invention, Figure 2-1 、 2-2 , 3, and 4: the alarm component 202 of the early warning circuit is connected in series with the near-electric induction switch 201 and is built into a circuit board to form a near-electric induction switch and alarm component 208; the near-electric induction switch and alarm component 208 can be adjusted to four gears through the gear button 1; they are 220V, 35kV, 110kV, and 220kV, of which 220V is the test voltage; the maximum sensing distance of 35kV is 1.5 meters, the maximum sensing distance of 110kV is 2.5 meters, and the maximum sensing distance of 220kV is 3.0 meters; when the field strength of the corresponding gear voltage level is sensed, the near-electric induction switch probe thereon makes the switch normally closed, otherwise it is normally open.

[0054] As a preferred embodiment of the present invention, Figure 2-1 、 2-2 As shown in Figures 3 and 4, the warning circuit consists of six infrared sensors 203 connected in parallel. Each infrared sensor switch 203 has an infrared sensor contact with a 110° cone angle sensing range, providing three-dimensional infrared sensing of humans or birds. Each infrared sensor switch 203 is equipped with an infrared sensing distance adjustment knob 206 and a relay closing delay adjustment knob 207. The infrared sensing distance can be adjusted to a maximum of 5 meters, and the maximum relay closing delay after infrared triggering can be adjusted to 300 seconds. With the six infrared sensors 203 connected in parallel, the infrared sensing contacts 4 are evenly mounted on the side of the packaging box, providing 360° sensing. Actuation of one infrared sensor switch 203 activates the parallel circuit. When this component senses a field strength corresponding to the voltage level, the proximity sensor probe on it switches the switch to a normally closed state; otherwise, it remains normally open. The alarm component and the proximity sensor switch are connected in series and integrated into a single circuit board. When the circuit is activated, the alarm component emits a continuous, sharp sound, alerting maintenance personnel or scaring birds away.

[0055] The warning circuit primarily consists of a proximity sensor switch, an alarm module, an infrared sensor switch, an energy storage battery, and a solar panel. These three components are connected in series. The alarm module will only activate a long-duration alarm when both the proximity sensor and the infrared sensor are simultaneously closed. Even if direct sunlight on the infrared sensor contacts causes the relay to malfunction, this still proves the circuit is live and provides a bird-repellent effect.

[0056] Working status of the early warning circuit: When the line is energized, the proximity sensor switch is in the normally closed state. If maintenance personnel or birds enter the crossarm, the infrared sensor contact is triggered and is at a high potential. The relay is automatically connected, the circuit is connected, and the alarm component emits a continuous sharp sound to warn the maintenance personnel or scare the birds away; when the line is out of power, the proximity sensor switch is in the normally open state. If maintenance personnel or birds enter the crossarm, the infrared sensor contact is triggered and is at a high potential. The relay is automatically connected, but because the proximity sensor switch, alarm component, and infrared sensor switch are connected in series, the alarm component only emits two sharp sounds, indicating that the circuit is normal and there is no power in the high-voltage transmission line.

[0057] As a preferred embodiment of the present invention, Figure 2-1 、 2-2 As shown in , 3, and 4: the bird-proofing component is a bird-proofing spike or a windmill-type bird repellent; the lower end of the bird-proofing spike and the windmill-type bird repellent can be changed to a threaded design to facilitate the fixation of the packaging box, and the thread is adapted to a nut of corresponding size. After the packaging box is put on the lower end of the bird-proofing device, it can be fastened and fixed by the nut, which can achieve a better matching effect.

[0058] The bracket assembly includes a clamping plate I12 and a clamping plate II13 for clamping the crossarm; the clamping plate I12 and the clamping plate II13 are both L-shaped structures, and the clamping plate I12 and the clamping plate II13 are provided with corresponding longitudinal through holes and transverse through holes; the longitudinal through holes are penetrated by longitudinal assembly bolts 15, and the top of the longitudinal assembly bolts 15 is connected to the assembly part 9; the transverse through holes are penetrated by transverse assembly bolts 16.

[0059] As a preferred embodiment of the present invention, Figure 6 As shown: the bird-proof spikes are multiple stainless steel spikes that radiate out in an inverted umbrella shape with the assembly portion 9 as the bottom center.

[0060] As a preferred embodiment of the present invention, as shown in the figure: the windmill-type bird repeller uses natural wind as its power, blows the bowl-shaped fan blades with wind, drives the reflective mirror inside the bowl-shaped fan blades to rotate, and continuously emits intermittent reflected light.

[0061] In summary, the present invention has a new type of integrated sound and light bird-proofing device with an early warning function to prevent accidental entry into the crossarm of an energized line. By filling the prevention loopholes of the original bird-proofing device with sound and light, it ensures that there are no blind spots in the prevention area of ​​the bird-proofing device, avoids the occurrence of bird-damaged tripping accidents on the transmission line, and can effectively ensure the safe and stable operation of the line. At the same time, after the new bird-proofing device is installed on the crossarm, the light on it adopts a red light that flashes constantly at night and flashes continuously at night. It can set off the shape and structure of the tower at night, and use dots and lines to outline the direction of the line, which serves as a warning to nighttime construction workers near the tower, and prevents the line tower from being damaged by external forces such as large machinery at night. Therefore, the invention adds the function of preventing the tower from being damaged by external forces on the basis of the original bird-proofing function. This invention can also make full use of the location advantage of the bird-proofing device to prevent maintenance personnel from mistakenly entering the crossarm on the side of the energized line: when the line is energized, the maintenance personnel enter the crossarm and an early warning sound is issued; when the line is out of power, the maintenance personnel enter the crossarm and no early warning sound is issued, thus avoiding the risk of personal electric shock and improving the inherent safety level of high-voltage transmission lines. The development plan of this new bird-proofing device is easy to manufacture and has strong practicality. Currently, there is no research and design in this regard in the country. After the new bird-proofing device is put into use, it can effectively improve the level of bird damage prevention and control of transmission lines, effectively avoid the risk of maintenance personnel mistakenly entering the crossarm of energized lines, ensure the personal safety of maintenance personnel, and improve the inherent safety level of the lines. Specifically:

This invention can fill the defense loopholes of the original bird-proofing devices (bird-proof spikes, windmill-type bird repellers, etc.) with sharp sounds and flashing lights, ensuring that there are no blind spots in the defense space of the bird-proofing devices, avoiding the occurrence of bird-damaged tripping accidents on power transmission lines, and effectively ensuring the safe and stable operation of the lines.

[0063] 2. After the invention is installed on the cross arm, the light on it adopts a red light that flashes constantly at night and keeps flashing at night. It can set off the shape and structure of the tower at night, and use dots and lines to outline the direction of the line, which serves as a warning to night construction workers near the tower, and prevents the line tower from being damaged by external forces such as large machinery at night. Therefore, the invention innovatively adds the function of preventing the tower from being damaged by external forces on the basis of the original bird damage prevention function.

[0064] 3. The invention makes full use of the location advantage of the bird-proofing device and establishes a near-electric induction warning module, so that the invention has a warning function to prevent maintenance personnel from accidentally entering the crossarm on the side of the energized line: when the line is energized, the maintenance personnel enter the crossarm and a warning sound is issued; when the line is out of power, the maintenance personnel enter the crossarm and no warning sound is issued, effectively avoiding the risk of personal electric shock and improving the inherent safety level of high-voltage transmission lines.
