Description

Technical Field

[0001] The present invention relates to the technical field of power protection equipment, and in particular to a swing-type internal protection device for high-voltage line towers. Background Art

[0002] With the development of the economy, the stable development of the national power industry is directly related to the economic development of our country. In recent years, in the statistics of transmission line accidents, high-voltage towers are prone to collapse after being affected by external forces such as earthquakes and strong winds, causing large-scale power outages and personal injuries, which is extremely dangerous; the accidents of birds causing line tripping not only increase gradually, but also show an upward trend, having a great impact on the safe operation of the power grid.

[0003] As the main support for carrying high-voltage lines, the tower structure of high-voltage towers is suitable to be the first choice for building bird nests, increasing the potential safety hazards of high-voltage towers. Birds will build many bird nests on the tower frames of the tower body. The bird nests not only affect power safety, but also bring unnecessary troubles to power workers for maintaining power line towers. Therefore, the anti-bird nest structure for the tower structure of high-voltage towers is also crucial. The existing bird repellers mainly include windmill-type, sound, ultrasonic and other bird repellers. However, most of the existing bird repelling devices are installed on the cross arm through wind vanes, and their working range is very small, and they cannot effectively drive away the birds at the tower frame. Therefore, there is an urgent need for a bird repelling device with a large working range for high-voltage line tower bodies. Summary of the Invention

[0004] To solve the technical problems in the background art, the present invention proposes a swing-type internal protection device for high-voltage line towers, which uses a swing member to scare and drive away the birds at the frame. The swing member can swing with the wind and drive away the birds at the frame during the swinging process. At the same time, the moving platform can move left and right, thereby adjusting the shortest distance from the swing member to the frame, with better effects and being suitable for popularization.

[0005] A swing-type internal protection device for high-voltage line towers proposed by the present invention includes a connecting base, a connecting rod, a slide rail, a moving platform, and a swing member. It is characterized in that the swing member includes a plurality of monomers from top to bottom, the monomers are connected by connecting ropes, and the monomers can swing left and right with the wind.

[0006] As a further improvement of the present invention, limiting blocks are provided on both sides of the slide rail. One end of the connecting rod is fixedly connected to the connecting base, and the other end is fixedly connected to the limiting block. The moving platform comprises a base, a wind blade, a support rod, a transmission gear, a rotating rod and a knocking rod. A slideway is provided on the base, and the slideway cooperates with the slide rail. One side of the base is fixed with a telescopic spring, and the other end of the telescopic spring is fixedly connected to the limiting block. A support rod is fixed above the base. The wind blade is rotationally matched with the support rod. The rotating rod is connected to the base through a rotating member. The end of the wind blade is matched with the top of the rotating rod through a transmission gear. A knocking rod is fixedly provided at the bottom of the rotating rod. A swinging member is connected below the base, and the knocking rod extends into the swinging member. The swinging member is formed by connecting a plurality of monomers through connecting ropes.

[0007] As a further improvement of the present invention, the swinging member is successively the first monomer, the second monomer... the (N - 1)th monomer, the Nth monomer from top to bottom, and they are connected by connecting ropes. Each monomer is a hollow cylinder structure. The first monomer is fixedly connected to the base. A metal sheet is provided inside the second monomer for cooperating with the knocking rod.

[0008] As a further improvement of the present invention, wind-catching structures are provided on both sides of the second monomer... the (N - 1)th monomer, the Nth monomer.

[0009] As a further improvement of the present invention, connecting holes are provided at the bottommost and topmost parts of the monomer.

[0010] As a further improvement of the present invention, the connecting rope is an elastic rope.

[0011] As a further improvement of the present invention, the second monomer is composed of an upper fixed end and a lower movable end. The upper fixed end is a "T"-shaped hollow structure, and an edge is provided below the upper fixed end. An inverted "L"-shaped connecting plate is provided above the lower movable end, and a return spring is provided between the inverted "L"-shaped connecting plate and the edge. A metal sheet is provided on the inner wall of the upper fixed end.

[0012] As a further improvement of the present invention, the connecting rod, the base, the wind blade, the support rod, the swinging member, and the wind-catching structure are all made of lightweight plastic materials.

[0013] As a further improvement of the present invention, the surface of the monomer is coated with green snake patterns, and the surface of the Nth monomer is in the shape of a snake head.

[0014] As a further improvement of the present invention, the connecting base is fixedly connected to the frame of the high-voltage tower, and the length of the connecting rod is 30 - 40 cm.

[0015] The beneficial technical effects of the present invention are:

[0016] (1) The swing member of the present invention is formed by connecting several monomers. The monomers are made of lightweight plastic material and can swing with the wind. The surface of the monomers is coated with green snake patterns, which can scare the birds near the frame during the left and right swinging process, and the driving effect is remarkable.

[0017] (2) In the present invention, the wind blade moves left and right with the mobile platform. During the left and right movement of the mobile platform, the shortest distance between the swing member and the frame is adjusted, so that the distance of the Nth monomer of the swing member is unpredictable, and its snake head shape is more likely to drive away birds.

[0020] (5) The second monomer is composed of an upper fixed end and a lower mobile end, which are connected by a return spring, so that the second monomer has a certain contraction ability, can further increase the length of the swing member, and adjust the swing amplitude of the lower monomer. When its length is uncontrollable, the action range at the tower body is larger and it is suitable for popularization. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, if the terms "first", "second", "third" are used, they are only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0030] As shown in the figure, a swing-type internal protection device for a high-voltage tower includes a connection base 1, a connecting rod 2, a slide rail 3, a moving platform 4, and a swing member 5. The swing member 5 includes a plurality of monomers 51 from top to bottom. The monomers 51 are connected by connecting ropes and can swing left and right with the wind. During the process of the monomers 51 swinging left and right, they will continuously approach the tower body of the high-voltage tower to drive away the birds staying on it.

[0031] Specifically, limit blocks are provided on both sides of the slide rail 3. The limit blocks have a certain height to limit the movement of the moving platform 4. One end of the connecting rod 2 is fixedly connected to the connection base 1, and the other end is fixedly connected to the limit block. The moving platform 4 includes a base 41, a wind blade 42, a support rod, a transmission gear, a rotating rod 43, and a knocking rod 44. A slideway is provided on the base 41, and the slideway is matched with the slide rail 3. One side of the base 41 is fixed with a telescopic spring 411, and the other end of the telescopic spring 411 is fixedly connected to the limit block. A support rod is fixed above the base 41. The wind blade 42 is rotatably matched with the support rod. The rotating rod 43 is connected to the base 41 through a rotating member and can rotate relative to the base 41. The end of the wind blade 41 is matched with the top of the rotating rod 43 through a transmission gear. The transmission gears are mutually meshed helical gears. A knocking rod 44 is fixedly provided at the bottom of the rotating rod 43. The swing member 5 is connected below the base 41, and the knocking rod 44 extends into the swing member 5. The swing member 5 is composed of a plurality of monomers 51 connected by connecting ropes.

[0032] Specifically, the swinging member 5 from top to bottom is successively the first monomer, the second monomer... the (N - 1)th monomer, the Nth monomer, which are connected to each other by connecting ropes. Each monomer 51 is a hollow cylinder structure. The first monomer is fixedly connected to the base. The second monomer is provided with a metal sheet 52 inside. The metal sheet 52 is used to cooperate with the knocking rod 44. When the wind blade 42 rotates, the wind blade 42 drives the rotating rod 43 to rotate, and then drives the knocking rod 44 to rotate in the swinging member 5, and the knocking rod 44 knocks on the metal sheet 52 to make a sound.

[0033] Specifically, on both sides of the second monomer... the (N - 1)th monomer, the Nth monomer, there are wind-catching structures, where the wind-catching structure is a plate or a wind bowl. The main function of the wind-catching structure is to increase the force on the monomer 51 and help the monomer 51 deflect and move when making a sound.

[0034] Specifically, connection holes are provided at the bottom and top of the monomer 51 for connecting and fixing each other through connecting ropes.

[0035] Specifically, the connecting rope is an elastic rope. The connecting rope uses an elastic rope, which has a certain length expansion and contraction ability. When the lower monomer 51 is subjected to a large force, the elastic rope is stretched to adjust the swinging distance of the lower monomer, and the driving range of the swinging member 5 is larger.

[0036] As a preferred technical solution of the present invention, the second monomer is composed of an upper fixed end 53 and a lower movable end 54. The upper fixed end 53 is a "T"-shaped hollow structure. There is an edge 531 below the upper fixed end 53. There is an inverted "L"-shaped connecting plate above the lower movable end 54. A return spring 532 is provided between the inverted "L"-shaped connecting plate and the edge 531. A metal sheet 52 is provided on the inner wall of the upper fixed end 53, making the second monomer have a certain contraction ability, which can further increase the length of the swinging member and adjust the swinging amplitude of the lower monomer. When the length is uncontrollable, the acting range on the tower body is larger.

[0037] Specifically, the connecting rod 2, the base 41, the wind blade 42, the support rod, the swinging member 5, and the wind-catching structure are all made of lightweight plastic materials.

[0038] Specifically, the surface of the monomer 51 is coated with green snake patterns, and the surface of the Nth monomer is in the shape of a snake head. When the swinging member 5 sways with the wind, the swinging distance and amplitude of the Nth monomer are the largest, and designing it in the shape of a snake head has the best driving effect.

[0039] Specifically, the connecting base 1 is fixedly connected to the frame of the high-voltage tower, and the length of the connecting rod is 40 cm.

[0040] The swing member 5 of the present invention is formed by connecting a number of monomers 51. The monomer 51 is made of lightweight plastic material and can swing with the wind. The surface of the monomer 51 is coated with green snake patterns, which can startle the birds near the frame during the left and right swinging process, and the driving effect is remarkable. In the present invention, the wind blade 42 moves left and right with the mobile platform 4. During the left and right movement of the mobile platform 4, the shortest distance between the swing member 5 and the frame is adjusted, so that the distance of the Nth monomer of the swing member 5 is unpredictable, and its snake head shape is more likely to drive away birds. During the rotation of the wind blade 42, the rotating rod 43 and the knocking rod 44 are driven to rotate through the transmission gear, and the knocking rod 44 knocks on the metal sheet 52 in the second monomer to make a sound for the purpose of driving away. The connecting rope is an elastic rope, which has a certain length expansion and contraction ability. When the lower monomer is subjected to a large force, the elastic rope is stretched to adjust the swing amplitude of the lower monomer. The second monomer is composed of an upper fixed end 53 and a lower moving end 54, which are connected by a return spring 532, so that the second monomer has a certain contraction ability, can further increase the length of the swing member, and adjust the swing amplitude of the lower monomer. When its length is uncontrollable, the action range at the tower body is larger, which is suitable for popularization.

[0041] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
