Description

Technical Field

[0002] Power towers are the main equipment for power transmission in modern society. Power towers are mainly used to erect high-voltage transmission lines. Due to the high height of power towers, in some areas with typhoons or prone to ground subsidence, the wind resistance and stability requirements of power towers are very high. At present, the common wind resistance measures for transmission towers are mainly focused on the use of ground rope reinforcement and the streamlined structure design. The ground ropes can enhance the stability of the power tower to a certain extent. By connecting with the anchor points on the ground, they provide additional lateral tension for the tower to resist the horizontal force generated by strong winds. However, after a long period of strong wind attacks, the anchor points are repeatedly stretched, vibrated and eroded by environmental factors, and the anchor points are prone to loosening; in addition, with the increasing prominence of environmental problems, the construction of transmission towers also needs to consider the impact on the surrounding ecological environment.

The winding drum 103 is sleeved on the frustum, and the inner wall of the winding drum 103 is rotatably connected to the circumferential surface of the two frustums on the frustum 102. The winding drum 103 can be on the frustum 102 along the axis of the frustum 102 slides in the extension direction; a first cavity is provided between the inner wall of the winding drum 103 and the conical surface of the cone 102, the first cavity is filled with damping grease 106, the damping grease 106 does not completely fill the first cavity, and the interior of the first cavity is at positive pressure; the pull rope 104 is wound on the winding drum 103, and one end of the pull rope 104 is fixedly connected to the winding drum 103, and the other end of the pull rope 104 is connected to the ground, and the extension direction of the pull rope 104 between the winding drum 103 and the ground is perpendicular to the extension direction of the axis of the cone 102; the booster part is used to control the inner wall of the winding drum 103 to approach the conical surface of the cone 102 when the iron tower 100 swings in the direction away from the end of the pull rope 104 connected to the ground.

[0031] A pull rope 104 is provided so that the swing amplitude of the iron tower 100 can be reduced when the iron tower 100 is swung by wind, thereby increasing the stability of the iron tower 100; a damping grease 106 is provided between the winding drum 103 and the cone 102, so that the iron tower 100 is subjected to resistance when it swings and the instantaneous tension on the pull rope 104 is reduced, so that the pull rope 104 will not break and the connection part between the pull rope 104 and the ground will not be easily loosened; a booster part is provided so that when the winding drum 103 rotates, the volume of the first cavity can be reduced, so that the relative rotation resistance between the winding drum 103 and the roller is increased, thereby reducing the swing amplitude of the iron tower 100.

[0032] In this embodiment, the booster part includes a rotating drum 105, a first fixing ring 107 and a second fixing ring 108. The rotating drum 105 is arranged in the fixed box 101, the first fixing ring 107 is sleeved on the rotating drum 105, and the first fixing ring 107 is fixedly connected to the rotating drum 105, the second fixing ring 108 is fixedly installed on one end of the winding drum 103, and the end of the second fixing ring 108 away from the winding drum 103 abuts against the first fixing ring 107, and the first fixing ring 107 and the second fixing ring 108 abut against each other. The surfaces on which the first fixing ring 107 and the second fixing ring 108 abut against each other are both provided with inclined surfaces, and the inclined surfaces on the first fixing ring 107 are adapted to the inclined surfaces on the second fixing ring 108; when the pull rope 104 pulls the rotating drum 105 to rotate, the rotating drum 105 moves along the extension direction of the axis of the cone 102 through the cooperation of the inclined surfaces on the first fixing ring 107 and the second fixing ring 108, and the first cavity body The area is reduced, the first fixing ring 107 and the second fixing ring 108 are closer to the small end of the cone 102 than the large end of the cone 102, the inclined surfaces at the ends of the first fixing ring 107 and the second fixing ring 108 are spiral and extend along the extension direction of the axis of the cone 102, the rotation direction of the inclined surfaces on the first fixing ring 107 and the second fixing ring 108 is consistent with the rotation direction of the pull rope 104 on the winding drum 103, when the pull rope 104 pulls the winding drum 103 to rotate, the winding drum 103 drives the second fixing ring 108 to move along the inclined surface on the first fixing ring 107 in the direction away from the first fixing ring 107, so that the damping between the winding drum 103 and the cone 102 is increased, and the resistance to the rotation of the winding drum 103 is increased, thereby reducing the swing amplitude of the iron tower 100, while preventing the pull rope 104 from being subjected to excessive instantaneous tension at the connection position on the ground.

[0033] In this embodiment, a conical surface is provided on the inner wall of the winding drum 103, and the conical surface of the winding drum 103 and the conical surface of the cone 102 are coaxial and parallel. Two annular grooves are provided on the inner wall of the winding drum 103, and the two annular grooves are located on both sides of the conical surface of the winding drum 103 in the extension direction of the axis of the cone 102, and the two annular grooves are coaxial with the cone 102, and the two annular grooves are in close contact with the two cones on the cone 102 respectively. When the winding drum 103 slides on the turntable along the extension direction of the axis of the cone 102, the conical surface of the winding drum 103 and the conical surface of the cone 102 will move away from or approach each other. When moving away from each other, the volume of the first cavity increases, the flow space of the damping grease 106 in the first cavity increases, the rotational resistance between the winding drum 103 and the cone 102 will decrease, and the two are more likely to rotate relative to each other; conversely, it is less likely for the winding drum 103 and the cone 102 to rotate relative to each other.

[0034] In this embodiment, the buffer mechanism further includes a one-way drive component and a swing component. The rotating drum 105 is coaxial with the cone 102, and the rotating drum 105 is rotatably arranged in the fixed box 101. The one-way drive component is used to make the rotating drum 105 rotate in one direction. When the rotating drum 105 rotates, the first fixed ring 107 rotates relative to the second fixed ring 108. The inclined surface on the first fixed ring 107 pushes the second fixed ring 108 to move toward the cone 102, further improving the damping between the winding drum 103 and the cone 102. At the same time, the rotating drum The rotation of 105 will make the winding drum 103 tend to wind the pull rope 104 around its own circumference through the damping grease 106, indirectly improving the resistance of the winding drum 103 to release the pull rope 104, and reducing the swing amplitude of the iron tower 100. The swing assembly includes a pendulum 110, one end of the pendulum 110 is rotatably set in the fixed box 101, and the other end of the pendulum 110 is located below its rotation axis due to the influence of gravity. When the iron tower 100 swings, the pendulum 110 can rotate around its own axis due to inertia and drive the rotating drum 105 to rotate through the one-way drive assembly.

[0035] In this embodiment, the swing assembly further includes a first fixed shaft 112, a first gear 113, a second fixed shaft 114 and a second gear 115. The first fixed shaft 112 is rotatably disposed in the fixed box 101, and the first fixed shaft 112 is coaxial with the cone 102. The first gear 113 is fixedly mounted on the first fixed shaft 112, and the first gear 113 is coaxial with the first fixed shaft 112. The second fixed shaft 114 is rotatably disposed in the fixed box 101, and the second fixed shaft 114 is located below the first fixed shaft 112. The second fixed shaft 114 extends along the extension direction of the axis of the cone 102. The second gear 115 is rotatably disposed in the fixed box 101, and the first gear 113 is fixedly mounted on the first fixed shaft 112, and the first gear 113 is coaxial with the first fixed shaft 112. The second gear 115 is sleeved on the second fixed shaft 114, the second gear 115 is meshed with the first gear 113, and the diameter of the second gear 115 is smaller than the diameter of the first gear 113. One end of the pendulum 110 is fixedly connected to the second gear 115, and the other end of the pendulum 110 is located below the second gear 115 due to the influence of gravity. When the iron tower 100 is swung by the wind, the pendulum 110 drives the second gear 115 to swing around the second fixed shaft 114 due to inertia. The rotation of the second gear 115 will drive the first gear 113 to rotate. The second gear 115 will provide a large torque to the first gear 113, so that the first gear 113 can rotate easily.

[0036] In this embodiment, the one-way drive assembly includes a first ratchet 116, a first pawl 117, a second ratchet 118 and a second pawl 119. The first ratchet 116 is disposed on the drum 105, and the first ratchet 116 is coaxial with the drum 105. The first pawl 117 is rotatably disposed in the fixed box 101, and the first pawl 117 can be engaged with the first ratchet 116. The second ratchet 118 is sleeved on the first fixed shaft 112, and the second ratchet 118 is coaxial with the first fixed shaft 112. The rotation direction of the ratchet teeth on the first ratchet 116 is opposite to that on the second ratchet 118. The second pawl 119 is rotatably arranged on the drum 105, and the second pawl 119 can be engaged with the second ratchet 118. Torsion springs are arranged between the first pawl 117 and the first ratchet 116, and between the second pawl 119 and the second ratchet 118, so that the first pawl 117 and the first ratchet 116, and between the second pawl 119 and the second ratchet 118 are always in contact; the first fixed shaft 1 When the first fixed shaft 112 rotates to drive the second ratchet 118 to rotate, the second ratchet 118 can drive the rotating drum 105 to rotate through the second ratchet pawl 119, and the rotating drum 105 can drive the first ratchet 116 to rotate relative to the first ratchet pawl 117. Similarly, when the first fixed shaft 112 rotates to drive the second ratchet 118 to rotate in the opposite direction, the second ratchet 118 can go over the second ratchet pawl 119 and continue to rotate. The second ratchet 118 will rotate relative to the second ratchet pawl 119, and the rotating drum 105 will rotate between the first ratchet pawl 117 and the first ratchet pawl 117. The first ratchet 116 will not reverse either. Therefore, when the iron tower 100 swings, the pull rope 104 will not drive the rotating drum 105 to rotate through the winding drum 103. Relative rotation will occur between the rotating drum 105 and the winding drum 103. Under the action of the damping grease 106, the rotation of the winding drum 103 encounters resistance. At the same time, the pendulum 110 can swing back and forth, and will only drive the rotating drum 105 to rotate by swinging in one direction, so that the damping between the rotating drum 105 and the winding drum 103 is increased.

[0037] In this embodiment, two unidirectional drive components and two buffer components are provided, and the two unidirectional drive components are symmetrical about a plane passing through the center point of the first fixed axis 112 and perpendicular to the first fixed axis 112. The two buffer components are also symmetrical about a plane passing through the center point of the first fixed axis 112 and perpendicular to the first fixed axis 112. The connection parts between the two pull ropes 104 in the two buffer components and the ground are located on both sides of the iron tower 100. The reciprocating swing of the iron tower 100 can be restricted by the pull ropes 104. At the same time, the swing of the pendulum 110 can drive the corresponding rotating drum 105 to rotate through one of the unidirectional drive components.

[0038] In this embodiment, bearings are respectively provided between the rotating drum 105 , the first fixed shaft 112 , the second fixed shaft 114 and the fixed box 101 , so that the rotating drum 105 , the first fixed shaft 112 and the second fixed shaft 114 can rotate more smoothly.

[0039] In this embodiment, a spiral groove 120 is provided on the winding drum 103, and the pull rope 104 wound on the winding drum 103 is located in the spiral groove 120. The spiral groove 120 makes it easier for the pull rope 104 to be wound on the winding drum 103 and less likely to slide in the extension direction of the axis of the cone 102.

[0040] In this embodiment, a plurality of buffer mechanisms are provided, and the connection points between the pull ropes 104 in the plurality of buffer mechanisms and the ground are evenly distributed around the iron tower 100. The plurality of pull ropes 104 fix the iron tower 100 more stably, and when the wind from different directions blows the iron tower 100, the iron tower 100 can be subjected to the tension from the pull ropes 104.

[0041] The use principle of a wind-resistant transmission tower provided in the above embodiment is:

[0042] Taking the buffer assembly in one of the buffer mechanisms as an example, firstly, the end of the pull rope 104 away from the winding drum 103 is installed on the ground. When the iron tower 100 is affected by the environment and swings, the winding drum 103 corresponding to the pull rope 104 under tension will move away from the connection point of the pull rope 104 on the ground, and the length of the pull rope 104 between the winding drum 103 and the ground increases. The pull rope 104 drives the winding drum 103 to rotate, and the rotation of the winding drum 103 drives the second fixing ring 108 to rotate. The second fixing ring 108 rotates through its own inclined surface and the first fixing ring 108 rotates. With the cooperation of the inclined surface on the first fixing ring 107, the winding drum 103 moves in the direction away from the first fixing ring 107, and the conical surface of the winding drum 103 approaches the conical surface of the cone 102. The volume of the first cavity is reduced, and the flow space of the damping grease 106 is reduced. The friction and collision between the molecules of the damping grease 106 increase, which leads to an increase in the damping force, and the rotational resistance between the winding drum 103 and the cone 102 increases. The speed of the winding drum 103 releasing the pull rope 104 will slow down, thereby providing resistance to the swing of the iron tower 100 and reducing the swing amplitude of the iron tower 100.

[0043] While the iron tower 100 is swinging, the pendulum 110 rotates around the second fixed shaft 114 due to its own inertia. The rotation of the pendulum 110 drives the second gear 115 to rotate. The rotation of the second gear 115 drives the first gear 113 to rotate. The rotation of the first gear 113 drives the first fixed shaft 112 to rotate. The rotation of the first fixed shaft 112 drives the first ratchet 116 to rotate. The rotation of the first ratchet 116 drives the rotating drum 105 to rotate through the first pawl 117. The rotation direction of the rotating drum 105 is opposite to the rotation direction of the winding wheel. The rotation of the rotating drum 105 drives the first fixed ring 107 to rotate. The rotation of the first fixed ring 107, through the cooperation with the second fixed ring 108, will increase the moving speed of the winding drum 103, better provide rotation resistance between the winding drum 103 and the cone 102, and reduce the swing amplitude of the iron tower 100.

[0044] When the iron tower 100 recovers its original state after swinging, the iron tower 100 swings in the opposite direction, and the pendulum 110 swings in the opposite direction. The second gear 115 drives the first gear 113 to rotate in the opposite direction, and the first gear 113 drives the second ratchet 118 to reverse through the first fixed shaft 112. At this time, the second ratchet 118 will not drive the rotating drum 105 to rotate through the second pawl 119; when the iron tower 100 is reset, the tension on the pull rope 104 gradually decreases to its original size. During the process, due to the positive pressure in the first cavity, the winding drum 103 will move in the opposite direction along the extension direction of the axis of the cone 102 and approach the first fixed ring 107. With the cooperation of the first ratchet 116 and the first pawl 117, the rotating drum 105 will not rotate in the opposite direction. Under the guidance of the inclined surfaces of the first fixed ring 107 and the second fixed ring 108, the winding drum 103 rotates in the opposite direction to wrap around the pull rope 104; the two buffer components in the same buffer mechanism move in opposite directions, providing tension in opposite directions for the iron tower 100.

[0045] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
