Description

Technical Field

[0001] The present invention relates to the technical field of power transmission equipment, and in particular to a bird repelling device for a transmission line. Background Art

[0002] In recent years, with the continuous extension of the power grid and the improvement of the domestic ecological environment, and at the same time with the enhancement of people's awareness of protecting birds, the number of birds has been increasing, which has brought certain problems to the power industry. The activities of birds near overhead power lines have increased day by day. A large number of birds build nests and live on transmission lines. The bird droppings, bird nests and the birds themselves will cause huge safety hazards to overhead transmission lines. Statistical data shows that the number of line failures caused by bird activities has increased significantly, which has a certain impact on the safe operation of the power grid. The number of bird-related fault trippings generally shows an upward trend year by year and has become one of the main reasons for line failures, affecting the safe and stable operation of the power grid. The work of preventing bird damage is rather severe.

[0003] In order to protect power safety, humans have developed various bird repelling measures. For example, ultrasonic bird repelling: According to the fact that the auditory range of birds is larger than that of humans, a powerful high-power ultrasonic pulse is used to stimulate the auditory system of birds, making them unable to bear it and thus leaving the action range of the ultrasonic pulse. However, the generated wave has characteristics such as short propagation distance and fast attenuation in the air, so the action area is relatively small; intelligent voice bird repelling: Using electronic technology, combined with the principles of bionics and acoustics, playing sounds that can scare birds to achieve the purpose of driving away birds. However, birds have relatively strong adaptability. This method has an effect on driving away birds in the short term. Once the birds get used to the played sounds, the bird repelling effect will significantly decline; bionic biological bird repelling: Combining bionics to design a "hostile eagle eye" that birds are afraid of, which can make birds feel frightened and thus stay away from the area. When using this method, it cannot be blocked, and also due to the biological adaptability of birds, the bird repelling effect will also significantly decline after a long time.

[0004] The application document of the Chinese patent authorization announcement number CN207054618U, with the name of a bird repellent device for transmission lines, discloses a main body box, a solar panel, a vertical axis wind turbine, a laser emitter, an electric push rod and a voice player. The main body box is of a cuboid structure. An installation rod is arranged on the upper end face of the main body box. The installation rod includes a vertical rod and an arc rod. The lower end of the arc rod is fixedly connected to the vertical rod. The solar panel and the vertical axis wind turbine are respectively arranged on the vertical rod. The vertical axis wind turbine includes a plurality of blades and a blade fixing rod for installing the blades. Reflective lenses are arranged on both side faces of the blades. A plurality of vertical bird spikes are evenly distributed on the rod body of the blade fixing rod. The tail of the laser emitter is connected to the upper end of the arc rod through a pin shaft. This technical solution adopts a combined bird repellent method of laser and voice. The setting of the electric push rod and the vertical arm can enable the laser emitter to obtain a larger adjustment of the pitching angle and expand the bird repellent range. However, this adjustment has a certain regularity. After the electric push rod and the vertical arm adjust the angle, the pitching angle of the laser emitter is adjusted. Birds are easy to adapt to it, and the voice played is easier to adapt to. After a long time, its bird repellent effect will decline.

[0005] Therefore, the existing technologies generally have a small scope of action, high requirements for the environment, and are difficult to cope with the biological adaptability of birds, and the long-term bird repellent effect is weak. Summary of the Invention

[0006] In order to solve the problems existing in the prior art in the above-mentioned background technology, the present invention provides an improved bird repellent device for transmission lines.

[0007] The technical solution adopted by the present invention to solve its technical problems is: a bird repellent device for transmission lines, including a protective cover arranged on the transmission line, and further including a bottom support plate and a motor arranged in the protective cover. The motor is arranged on the bottom support plate. A rotating assembly is connected to the motor and drives the rotating assembly to rotate. A laser is arranged on the rotating assembly;

[0008] It further includes a U-shaped frame and an impact rod arranged on the bottom support plate. The U-shaped frame is located between the motor and the rotating assembly. The U-shaped frame is placed after being flipped by 90°. Its two side walls are parallel to the bottom support plate. The impact rod is arranged on the outer side surface of the bottom wall of the U-shaped frame. The rotation of the rotating assembly collides with the impact rod, causing the laser to form an irregular swing.

[0009] The protective cover of the present invention protects each component located inside the protective cover. When the motor and the laser are turned on, the laser emits a laser beam upward, and the motor also drives the U-shaped frame to rotate, thereby driving the rotating assembly. When the rotating assembly rotates, it will collide with the impact rod, causing the laser to swing irregularly. As a result, the laser beam emitted by the rotating laser can scan the bird repelling area irregularly by 360°, and birds will regard this irregular laser beam as a stick waved at them, so as to achieve the purpose of repelling birds. The bird repelling effect is better, and the scope of the bird repelling effect is wider. Through research, it is found that the visual system of birds is the most sensitive, especially for green lasers with a wavelength of 532nm, and the visual ability of birds to adapt to laser beams is poor and it is not easy to produce adaptability.

[0010] Further, the rotating assembly includes a rotating seat, an L-shaped large bracket, and a Z-shaped small bracket. Four L-shaped vertical rods are provided at the lower end of the U-shaped frame, and the bottoms of the four vertical rods are connected to the bottom support plate. The rotating seat is located above the U-shaped frame and is connected to the motor output shaft. The rotating seat is located below the large bracket and is connected to one side plate of the large bracket. A bearing is provided at the top of the other side plate of the large bracket, and a rotating column is inserted into the central part of the bearing;

[0011] The laser is arranged on the lower side plate of the small bracket. The middle plate of the small bracket is connected to the rotating column and is rotationally connected to the bearing, and the small bracket collides with the impact rod.

[0012] The motor of the present invention drives the rotating seat to rotate, driving the large bracket and the small bracket to rotate together. Since the small bracket, the rotating column and the bearing are rotationally connected, when the small bracket rotates, it collides with the impact rod, causing the small bracket and the rotating column to rotate irregularly with the bearing as the center, so that the laser beam of the laser also forms a circular and irregular swing. Birds will regard this irregular laser beam as a stick waved at them, so as to achieve the purpose of repelling birds and improve the bird repelling effect.

[0013] Further, a cross plate is fixedly arranged at the top of the upper side plate of the small bracket. The cross plate is located above the bearing, and a collision rod passing through the two is fixed on the upper side plate and the cross plate of the small bracket;

[0014] A several-character-shaped collision height adjustment seat is arranged on the outer side surface of the bottom wall of the U-shaped frame. The collision height adjustment seat is fixedly connected to the U-shaped frame by three screws. The impact rod is stuck between the middle protruding part of the collision height adjustment seat and the bottom wall of the U-shaped frame. The middle screw passes through the middle protruding part of the collision height adjustment seat and then is screwed into the bottom wall of the U-shaped frame. The impact rod is fixedly abutted between the middle screw and one side wall of the collision height adjustment seat, and the collision rod is used in cooperation with the impact rod.

[0015] The collision in the present invention is that the motor drives the rotating seat to rotate, driving the large bracket and the small bracket to rotate together. The small bracket drives the laser to rotate. During the rotation, the collision rod and the impact rod collide with each other, causing the small bracket to rotate irregularly with the bearing as the center, thereby completing the formation of a circular and irregular swing of the laser beam of the laser.

[0016] Further, a conductive slip ring and a connecting bearing are sequentially arranged between the motor and the rotating assembly from bottom to top. The output shaft of the motor passes through the conductive slip ring and is connected to the connecting bearing. The connecting bearing is connected to the rotating seat. The conductive slip ring is located in the U-shaped frame, and both ends of the conductive slip ring are connected to the two side walls of the U-shaped frame respectively;

[0017] The bird repelling device further includes a storage battery. The storage battery is electrically connected to the motor and the outer ring of the conductive slip ring, and the inner ring of the conductive slip ring is electrically connected to the laser.

[0018] The storage battery of the present invention can supply power to the motor and, through the conductive slip ring, to the laser, thereby meeting the power consumption of the bird repelling device and ensuring the normal operation of the bird repelling device. The storage battery greatly improves the convenience of installation and use of the bird repelling device; when the laser rotates continuously, the storage battery supplies power to the laser through the conductive slip ring, which can avoid winding when using wires for connection, and the connecting bearing ensures smooth and non-hysteretic rotation of the rotating assembly.

[0019] Further, the storage battery and the protective cover are fixed to the cross arm of the pole tower of the transmission line through brackets.

[0020] The storage battery and the protective cover of the present invention are connected to the transmission line through brackets, increasing the stability of the storage battery and the protective cover.

[0021] Further, a bird repelling device for a transmission line further includes a cooling fan, and the cooling fan is arranged on the bottom support plate and below the motor.

[0022] The cooling fan of the present invention can dissipate heat from components such as the motor and the laser, ensuring the normal operation of the bird repelling device.

[0023] Further, the top of the protective cover is made of a transparent material.

[0024] The top of the protective cover of the present invention is made of a transparent material, which does not affect the normal operation of the laser.

[0025] Further, a bird repelling device for a transmission line further includes a solar panel electrically connected to the storage battery, and the solar panel is fixed to the bracket.

[0026] The solar panel of the present invention can charge the storage battery, and can also supply power to the motor, the cooling fan and the laser through the slip ring, ensuring the power consumption requirements of the bird repelling device, enabling the bird repelling device to work normally and reducing energy consumption.

[0027] Furthermore, an outwardly extending convex block is provided at the upper end of the impact rod.

[0028] The beneficial effects of the present invention are as follows: By setting the U-shaped frame, the motor, the slip ring and the rotating seat are spaced apart, which can not only ensure the rotation of the rotating seat driven by the motor, but also ensure the normal power supply of the laser on the rotating seat; and the use of the slip ring avoids the entanglement when using wire connections; the rotation of the rotating seat drives the collision rod to collide with the impact rod, so that the laser forms an irregular swing and emits irregular laser light beams; the laser beams swing in a circular and irregular manner to scan the bird repelling area. When the laser beam scans and irradiates the birds, the birds cannot distinguish, and will mistake the irregularly swinging laser beam for a stick waving at the birds, so as to achieve the purpose of driving away the birds, thereby improving the bird repelling effect, being suitable for long-term bird repelling, and increasing the bird repelling range.

A conductive slip ring 5 is installed inside the U-shaped frame 6. The inner ring of the conductive slip ring 5 is electrically connected to the laser 5. The output shaft of the electric motor 2 sequentially penetrates through the mounting plate and the conductive slip ring 5. After the output shaft of the electric motor 2 passes through the conductive slip ring 5 and the U-shaped frame 6, it is connected to the connecting bearing.

[0038] A J-shaped collision height adjustment seat 20 is fixedly connected to the outer side wall of the bottom wall of the U-shaped frame 6 by bolts. The collision height adjustment seat 20 is fixedly connected to the U-shaped frame 6 by three screws. The impact rod 7 is clamped between the middle protruding part of the collision height adjustment seat 20 and the bottom wall of the U-shaped frame 6. The middle screw penetrates through the middle protruding part of the collision height adjustment seat 20 and then is screwed into the bottom wall of the U-shaped frame 6. The impact rod 7 is fixedly abutted between the middle screw and one side wall of the collision height adjustment seat 20.

[0039] A rotating assembly 3 is provided on the upper surface of the U-shaped frame 6. The rotating assembly 3 includes a rotating base 31, an L-shaped large bracket 32, and a Z-shaped small bracket 33. The rotating base 31 is located above the U-shaped frame 6 and is fixedly connected to the output shaft of the motor 2. The output shaft of the motor 2 is fixedly connected to the rotating base 31 through a connecting bearing. The rotating base 31 is located below the large bracket 32 and is fixedly connected to one side plate of the large bracket 32. A bearing 34 is fixedly connected to the top of the other side plate of the large bracket 32. A rotating column 35 is inserted into the central part of the bearing 34. One end of the rotating column 35 extending out of the bearing 34 is inserted and fixed on the middle plate of the small bracket 33, and the rotating column 35 is fixedly connected to the small bracket 33. A laser 4 is fixedly connected to the upper surface of the lower side plate of the small bracket 33. A cross plate 36 is fixedly provided at the top of the upper side plate of the small bracket 33, and the cross plate 36 is located above the bearing 34. A collision rod 37 passing through both of them is fixed on the upper side plate of the small bracket 33 and the cross plate 36. The collision rod 37 is used in cooperation with the impact rod 7 to form a collision. An outwardly extending convex block 71 is provided on the impact rod 7, which can increase the probability of collision between the collision rod 37 and the impact rod 7.

[0040] The light-emitting position of the laser 4 is from top to bottom, and the emitted laser beam is a second-level laser, which is harmless to the human eyes and will not cause harm to birds. At the same time, the upward irradiation method of the laser 4 will not mis-irradiate pedestrians and vehicles moving around.

[0041] A bird repelling device for a transmission line further includes a storage battery 21 fixed to the outside of the protective cover 9. A bracket 22 is installed on the cross arm 23 of the pole tower of the transmission line. A solar panel 24, a storage battery 21, and a protective cover 9 are fixedly connected to the bracket 22. The solar panel 24 is connected to the storage battery 21, and the storage battery 21 is electrically connected to the outer ring of the motor 2, the cooling fan 8, and the conductive slip ring 5.

[0042] The solar panel 24 can charge the storage battery 21 under sunlight irradiation conditions, and supply power to the motor 2, the conductive slip ring 5, and the cooling fan 8 while charging the storage battery 21. In the case where the power generation of the solar panel 24 is insufficient, it can only supply power to the motor 2, the conductive slip ring 5, and the cooling fan 8.

[0043] The working process of the present invention is as follows: The bird repelling device is installed on the cross arm 23 of the pole tower of the transmission line, the angle of the solar panel 24 is adjusted, and the initial position of the laser beam emitted by the laser 4 is directed at the area to be bird-repelled.

[0044] During the working period of bird repelling, the motor 2 and the cooling fan 8 are started. The storage battery 21 supplies power to the laser 4 through the conductive slip ring 5 to turn on the laser 4. The motor 2 drives the rotating seat 31 to rotate, and the rotating seat 31 drives the large bracket 32, the small bracket 33 and the laser 4 to rotate together, so that the collision rod 37 also rotates. During the rotation of the collision rod 37, it will collide with the impact rod 7. Since the small bracket 33 is rotatably connected to the bearing 34, after the collision rod 37 collides with the impact rod 7, it will generate irregular swings, driving the small bracket 33 to generate irregular swings, so that the laser beam of the laser 4 also forms circular and irregular swings, and performs circular and irregular scans on the bird repelling area. Birds will regard this irregular laser beam as a stick waved at them, so as to achieve the purpose of repelling birds. The cooling fan 8 can dissipate heat from the whole device, especially from the laser 4, to ensure the normal operation of the whole device.

[0045] According to the actual height of the collision rod 37, adjust the height of the impact rod 7. Loosen the screw at the middle position on the collision height adjustment seat 20 so that there is a clearance distance between the middle convex part of the collision height adjustment seat 20 and the impact rod 7, and then the impact rod 7 can be moved up and down. When the impact rod 7 is moved to a suitable height to make the collision rod 37 more compatible with the impact rod 7, then pass the screw at the middle position through the middle convex part of the collision height adjustment seat 20 and screw it into the bottom wall of the U-shaped bracket 6 to clamp the impact rod 7 so that the impact rod 7 is fixedly abutted between the screw and the side wall of the collision height adjustment seat 20.

[0046] Inspired by the ideal embodiments of the present invention described above, through the above description, relevant staff can make various changes and modifications completely within the scope without departing from the technical idea of this invention.
