Description

Technical Field

[0001] The utility model relates to the technical field of power transmission towers, in particular to a high-strength wind-resistant power transmission tower. Background Art

[0002] Power transmission towers are mainly used for erecting high-voltage transmission lines. Due to the high height of power transmission towers, in some areas with typhoons, the requirements for the wind resistance and stability of power transmission towers are very high.

[0003] In order not to expand the floor area, the existing power transmission towers usually only add multiple cross arms and diagonal bracing rods at the tower feet for reinforcement. However, this method not only increases the weight of the tower body of the power transmission tower, but also the torque received at the connection between the tower feet and the flange will be very large. When the tower body is directly blown by strong wind, it is easy for the tower feet to become loose or break, which will then cause the entire tower body to fall down, and it is also easy to cause deformation in the middle and upper parts of the tower body, which is very dangerous. Therefore, it is very important to enhance the wind resistance of power transmission towers. Summary of the Utility Model

[0020] Please refer to Figure 1 , a high-strength wind-resistant power transmission tower, including a tower body 10, a base 20, a displacement mechanism 30 and a plurality of flow guiding structures 40. The base 20 is installed on the bottom wall of the tower body 10 and embedded in the ground, and only the top surface part of the base 20 can be exposed above the ground. The lower end of the displacement mechanism 30 is installed in the base 20, and the displacement mechanism 30 has a movable part that can penetrate above the base 20 and is rotatably arranged outside the tower body 10. A plurality of flow guiding structures 40 are fixedly connected to the movable part of the tower body 10, and the plurality of flow guiding structures 40 are arranged in an array along the height direction of the movable part, so that the movable part of the displacement mechanism 30 can drive the plurality of flow guiding structures 40 to move and adjust their positions. The side of the flow guiding structure 40 facing away from the tower body 10 forms a cone, and the plurality of flow guiding structures 40 can be adjusted and moved so that the cone side of the plurality of flow guiding structures 40 is directly facing the side where the airflow blows, so that in strong wind weather, the flow guiding structures 40 can be used to guide and change the flow direction of the airflow flowing near them, so as to avoid the airflow directly blowing on the tower body 10 and avoid the tower body 10 directly receiving a large wind force, thereby reducing its tipping and deformation.

[0021] Refer to Figure 2, the base 20 may include an outer table body 21, an inner table body 22, a protective cover 23, and a maintenance cover 24. The outer table body 21 is inserted downward into the ground, and its top plane may be flush with the ground; an outer circular groove 210 is formed at the center of the upper surface of the outer table body 21, and the inner table body 22 is disposed in the outer circular groove 210 and concentrically distributed therewith. The inner table body 22 is embedded and fixed on the ground, and its top plane may be coplanar with the top plane of the outer table body 21, so that the top of the base 20 can be kept horizontal, and the tower body 10 can be supported and fixed above the base 20. An activity groove 220 through which the activity part of the displacement mechanism 30 passes is formed between the outer wall of the inner table body 22 and the inner wall of the outer circular groove 210, and the circular shape of the activity groove 220 matches the movement track of the activity part of the displacement mechanism 30. An opening is formed in the middle of the inner table body 22, and a maintenance cover 24 is detachably and fixedly connected to the opening of the inner table body 22. A protective cover 23 is fixedly connected below the maintenance cover 24, and the servo motor 31 of the displacement mechanism 30 can be installed and fixed in the protective cover 23.

[0022] Refer to Figure 3 , the displacement mechanism 30 may include a servo motor 31, a rotating bracket 32, a positioning bracket 33, several connecting brackets 34, several connecting plates 35, and at least one auxiliary component mounting rod 36. The output end of the servo motor 31 passes downward through the protective cover 23 and is fixedly connected to the rotating bracket 32 in a clamping manner. The top of the rotating bracket 32 is fixedly connected to the bottom of the positioning bracket 33. The positioning bracket 33 is movably sleeved outside the maintenance cover 24. Several connecting plates 35 are stacked in the height direction and fixedly connected into an integral structure. Several connecting brackets 34 are fixedly connected to the outer edge of the connecting plates 35, and a fixed connection is made between the end of the positioning bracket 33 extending outward and the adjacent connecting bracket 34. The several connecting brackets 34 and the several connecting plates 35 together form the activity part of the displacement mechanism 30, and under the drive of the servo motor 31, the rotating bracket 32 and the positioning bracket 33 can jointly drive the activity part to deflect and adjust its position. The connecting plate 35 can be used for welding and fixing the diversion structure 40. At least one auxiliary component mounting rod 36 is fixed between two adjacent groups of connecting brackets 34, and wind direction detection devices, such as devices for monitoring wind direction and wind speed, such as a wind vane and an anemometer existing in the prior art, can be installed on the auxiliary component mounting rod 36 and cooperate with the servo motor 31, so as to actively adjust the position of the diversion structure 40 according to the wind direction.

[0023] Refer to Figure 4, the diversion structure 40 includes a conical plate 41 and a plurality of reinforcing rib plates 42. The conical plate 41 is configured to be conical, and the plurality of reinforcing rib plates 42 are fixedly welded to the inner side of the conical plate 41. The conical plate 41 can be made into the illustrated shape through processing procedures such as bending and welding of carbon steel plates. The conical side thereof can cause the airflow to change the flowing direction after passing through, thereby reducing the direct blowing on the tower body 10, and thus reducing the force deformation or toppling of the tower body 10.

[0024] The system of the present invention may further include a control system for controlling the operation of the above servo motor to perform automatic operations of deflecting the movable part of the displacement mechanism and adjusting the position of the diversion structure. It should be understood that there is no particular limitation on this control system, and it can be implemented by control technologies in the prior art, which will not be elaborated herein.
