Description

Technical Field

[0001] This utility model relates to the field of power transmission technology, and more specifically to a lifting and folding wind-resistant power transmission tower. Background Technology

[0002] As a critical infrastructure in power transmission networks, the performance of power transmission towers directly affects the stability and reliability of power transmission. With the acceleration of urbanization and the continuous increase in electricity demand in remote areas, the construction scale of power transmission towers is constantly expanding, and more and more towers need to be built in areas with complex natural environments. Power transmission towers in windy areas face severe challenges.

[0003] Currently, the lifting and folding wind-resistant power transmission tower disclosed in publication number CN217353795U, while improving the stability of the tower to some extent—by fixing the foundation with a bottom-level fixed claw frame and a concrete base, reinforcing the stability of the top layer through the connection between the second sliding rod, the first connecting rod, the second connecting rod, the third connecting rod, and the tower top plate, and improving the stability of the middle layer by connecting the top and bottom layers with telescopic rods—still has the following problems in practical applications:

[0004] From the perspective of wind-resistant structure, when encountering extreme strong winds, such as hurricanes and typhoons, the existing wind-resistant structural design cannot effectively distribute the enormous stress acting on the entire tower. The uneven wind force experienced by different parts of the tower leads to severe local stress concentration, which may cause the tower to twist, tilt, or even collapse, seriously threatening the safety of power transmission.

[0005] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a liftable and foldable wind-resistant power tower in order to achieve a more practical purpose. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a lifting and folding wind-resistant power tower to solve the problems existing in the background art.

[0007] This utility model provides the following technical solution: a liftable and foldable wind-resistant power transmission tower, comprising a power transmission tower body, which is composed of multiple segmented tower bodies stacked sequentially to form an integral tower structure. The cross-section of each segmented tower body is trapezoidal, making the entire tower present a progressively smaller pyramid shape from bottom to top, i.e., the top segmented tower body is the smallest and the bottom segmented tower body is the largest, which helps to enhance the tower's stability in the vertical direction and its ability to resist wind forces from different directions. The segmented tower bodies are connected by reinforced connecting seats. Longitudinal X-shaped reinforcing ribs are arranged along the longitudinal direction of the tower between adjacent reinforced connecting seats. These longitudinal X-shaped reinforcing ribs extend upward from the bottom of the tower and penetrate the space between each reinforced connecting seat, further enhancing the longitudinal structural strength of the tower. At the same time, transverse X-shaped reinforcing ribs are also arranged inside each reinforced connecting seat. The transverse X-shaped reinforcing ribs form a cross support structure inside the reinforced connecting seat, improving the strength and stability of the reinforced connecting seat itself, thereby further ensuring the stability of the entire tower structure.

[0008] Furthermore, the outer surface of the main body of the power tower is provided with a protective mechanism, which includes an insulating rubber layer, a wind erosion resistant coating, and a metal protective shell.

[0009] Furthermore, the outer surface of the metal protective casing is provided with reflective warning strips.

[0010] Furthermore, both the longitudinal X-shaped reinforcing ribs and the transverse X-shaped reinforcing ribs are made of high-strength alloy steel with a yield strength of not less than 600MPa, in order to enhance the overall wind resistance of the tower.

[0011] Furthermore, the reinforced connecting seat is connected to the segmented tower body by high-strength bolts with a tensile strength grade of not less than 8.8 to ensure the stability of the connection.

[0012] Furthermore, the insulating rubber layer is used to prevent electrical leakage.

[0013] Furthermore, the angle between the hypotenuse and the base of the trapezoidal cross-section of the segmented tower body is 60°.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] This utility model features a segmented tower structure with a trapezoidal cross-section that gradually decreases in size from bottom to top, resembling a pyramid. Longitudinal X-shaped reinforcing ribs are installed between adjacent reinforcing connectors, and transverse X-shaped reinforcing ribs are installed inside the reinforcing connectors. This design effectively disperses stress acting on the entire tower body when facing strong winds, reducing localized stress concentration caused by uneven wind loads on different parts of the tower. This significantly reduces the risk of tower twisting, tilting, or collapse, substantially improving the stability of power transmission towers in windy environments and effectively ensuring the safety of power transmission.

[0016] This utility model incorporates a protective mechanism comprising an insulating rubber layer, a wind-erosion resistant coating, and a metal protective shell, with reflective warning strips installed on the outer surface of the metal protective shell. The insulating rubber layer prevents electrical leakage, ensuring the safe operation of the tower in adverse weather conditions; the wind-erosion resistant coating effectively resists wind and sand erosion of the tower surface, extending its service life; the metal protective shell enhances overall protective strength; and the reflective warning strips improve the tower's visibility at night or in low-visibility environments, preventing collisions. These designs comprehensively improve the tower's performance, enabling it to better adapt to various complex environments. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0025] It should be noted that the structures, proportions, sizes, etc., shown in the accompanying drawings of this specification are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the conditions under which this application can be implemented.

[0026] Example 1: The lifting and folding wind-resistant power transmission tower of this utility model is constructed with the main body 100 of the power transmission tower as the core. The main body 100 of the power transmission tower is ingeniously constructed by stacking multiple segmented tower bodies 110 in sequence to form the overall tower body structure.

[0027] The segmented tower section 110 features an ingenious design with a trapezoidal cross-section, exhibiting a progressively smaller pyramid shape from bottom to top. This unique design minimizes the size of the top segment 110 and maximizes the size of the bottom segment 110. This design not only enhances the tower's vertical stability but also significantly improves its ability to withstand wind forces from different directions, laying a solid foundation for the tower's stable operation under complex weather conditions.

[0028] The segmented tower sections 110 are tightly connected by reinforcing connectors 111. The reinforcing connectors 111 surround the connection points of the segmented tower sections 110.

[0029] Meanwhile, the installation of reinforcing ribs is crucial in the structural design of the tower. Between adjacent reinforcing connectors 111, longitudinal X-shaped reinforcing ribs 112 extend vertically, rising from the bottom of the tower and penetrating the space between each reinforcing connector 111, contributing to the improvement of the tower's longitudinal structural strength. Inside each reinforcing connector 111, transverse X-shaped reinforcing ribs 113 interweave to form a cross-bracing structure, further enhancing the strength and stability of the reinforcing connector 111 itself, thus comprehensively ensuring the stability of the entire tower's main structure.

[0030] Example 2: Based on Example 1, Example 2 further enriches and improves the functions and performance of the iron tower.

[0031] First, a protective mechanism 114 is carefully arranged on the outer surface of the main body 100 of the power transmission tower. The protective mechanism 114 is composed of an insulating rubber layer 115, a wind-erosion resistant coating 116, and a metal protective shell 117. The insulating rubber layer 115 acts like a safety shield, effectively preventing leakage and ensuring the tower can operate safely and stably even in severe weather conditions such as heavy rain and lightning. The wind-erosion resistant coating 116 is 3mm thick; this carefully designed thickness effectively resists wind and sand erosion on the tower surface, greatly extending the tower's service life and making it durable even in areas with high wind and sand intensity. The metal protective shell 117 provides even more robust external protection, enhancing the overall protective strength of the tower.

[0032] It is worth mentioning that reflective warning strips 118 are installed at 50-centimeter intervals on the outer surface of the metal protective shell 117. These reflective warning strips 118 can reflect light at night or in low visibility conditions, significantly improving the visibility of the tower and effectively avoiding collision accidents caused by poor visibility, thus ensuring the safety of surrounding personnel and passing vehicles.

[0033] Furthermore, the key structural components of the tower—the longitudinal X-shaped stiffeners 112 and the transverse X-shaped stiffeners 113—are both made of high-strength alloy steel. This material has a yield strength of no less than 600 MPa, and its excellent strength properties greatly enhance the tower's overall wind resistance, enabling it to stand firm in strong winds.

[0034] In terms of connection method, the reinforced connecting seat 111 and the segmented tower body 110 are connected by high-strength bolts, and the tensile strength grade of the bolts is not lower than 8.8. This high-strength connection method ensures the stability of the connection between the components, and there will be no loosening or falling off even under long-term external force.

[0035] Finally, the angle between the hypotenuse and the base of the trapezoidal cross-section of the segmented tower body 110 was optimized to 60° through precise mechanical calculations. This optimized angle further improves the overall stability and wind resistance of the tower, enabling it to cope with various challenges more easily in complex and ever-changing natural environments.

[0036] Through such design and improvement, the lifting and folding wind-resistant power tower of this utility model has achieved a high level in terms of structural stability, safety and environmental adaptability, providing a reliable infrastructure guarantee for power transmission.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
