Description

Technical Field

[0001] The present invention relates to the technical field of interactive supply and demand of power systems, and in particular to a variable-section flow-guiding high-wind-resistant triangular communication tower structure. Background Art

[0002] At present, communication towers mainly adopt single-tube towers, angle steel towers and guyed towers. Although single-tube towers are beautiful and easy to construct, their wind resistance is limited by their cross-sectional shape and wall thickness. Angle steel towers achieve high strength through truss structures, but they have the problems of large steel consumption and high maintenance costs. Guyed towers rely on external cable systems and have poor adaptability in complex terrains. As 5G base stations expand to wind-sensitive areas, the industry's requirements for the wind resistance of communication towers have increased. Existing tower types are generally structurally damaged or functionally failed under typhoon conditions above level 12, and the single-tube tower reinforcement solution increases the wall thickness, resulting in an increase in foundation cost. The wind speed rises by more than 30%. The optimized solution for angle steel towers adopts K-type node structure, which increases the number of node bolts by 50%, resulting in reduced installation efficiency. The hybrid structure solution adds a triangular stabilizer, which destroys the aerodynamic shape of the tower and increases the wind pressure coefficient by 15%. In addition, the existing reinforcement methods have core defects such as low material utilization, insufficient dynamic response suppression, and deterioration of aerodynamic performance. Traditional communication towers have a high risk of structural instability under strong wind conditions, the wind-resistant design leads to a surge in steel consumption and deterioration in economic efficiency, and it is difficult to coordinate the optimization of the tower's aerodynamic shape and structural stiffness. A new communication tower structure is urgently needed to solve these problems. Summary of the Invention

[0021] The tower assembly 5 includes a plurality of main columns 501, which are arranged in a triangle shape. A plurality of horizontal cross arms 502 are fixedly installed between the main columns 501, and a plurality of diagonal braces 503 are also fixedly installed between the main columns 501. The lengths of the multiple horizontal cross arms 502 decrease from bottom to top; A plurality of diagonal braces 503 are cross-connected between the plurality of main columns 501; Specifically, the tower assembly 5 includes a plurality of main columns 501, and the plurality of main columns 501 are arranged in a triangular shape to form a stable spatial geometric structure. The spacing between the main columns 501 increases from top to bottom at a gradient of 1:1.2:1.5. This variable cross-section design enables the bottom of the tower to have a stronger supporting force and can better resist the overturning moment caused by wind loads. A plurality of horizontal cross arms 502 are fixedly installed between the plurality of main columns 501. Each group of horizontal cross arms 502 includes 3 H-shaped steels, and the length decreases from bottom to top, which not only provides an installation platform for communication equipment, but also enhances the rigidity of the tower in the horizontal direction. A plurality of diagonal braces 503 are also fixedly installed between the plurality of main columns 501. The plurality of diagonal braces 503 are cross-welded between adjacent main columns 501 at an inclination angle of 45° to form a triangular truss network, which further improves the torsional rigidity and overall stability of the tower, and effectively suppresses lateral deformation caused by wind loads.

[0025] The power supply structure includes three connecting rods 904 fixedly mounted on the outer sides of the upper portions of the plurality of horizontal cross arms 502, wherein one end of two of the three connecting rods 904 is respectively fixedly connected to a solar panel 905, and the plurality of solar panels 905 are respectively fixedly connected to the upper portions of the plurality of warning signs 902, and a battery 906 is provided on the rear side of each of the plurality of solar panels 905; The warning sign 902 is electrically connected to the battery 906; Specifically, the power supply structure includes three connecting rods 904 that are fixedly mounted on the outer sides of the upper portions of the multiple horizontal cross arms 502, wherein one end of two of the connecting rods 904 is fixedly connected to a solar panel 905.

[0026] Working Principle: The tower assembly 5 serves as the supporting framework of the entire communication tower. Its three main columns 501 are arranged in an equilateral triangle, evenly distributing wind loads from all directions. The main columns 501 utilize a variable cross-section design, with spacing increasing from top to bottom at a gradient of 1:1.2:1.5, creating a narrow-at-top, wide-at-bottom structure. This provides stronger support at the base of the tower, better able to resist the overturning moment caused by wind loads. This also accommodates the increasing wind load characteristic of increasing height. Six sets of horizontal crossarms 502, each consisting of three H-shaped steel beams, provide a mounting platform for communication equipment and enhance the tower's horizontal rigidity. Multiple sets of diagonal braces 503 are cross-welded at a 45° angle between adjacent main columns 501, forming a triangular truss network. This further enhances the tower's torsional rigidity and overall stability, effectively suppressing lateral deformation caused by wind loads. When wind load acts on the tower body, the tower body assembly 5 gradually transfers the wind load to the foundation assembly through this spatial truss system, ensuring the stability of the structure.

[0027] The deflector 603 is a curved fiberglass shell secured to the leeward side of the main column 501 by a clamp. When wind blows across the tower, the deflector 603 guides the airflow along its curved surface, forming a wall-attached jet. This reduces the vortex area at the rear of the tower, lowering windward pressure by 30% and effectively minimizing wind resistance. The damper is installed in the middle of the horizontal crossarm 502. Each set consists of a 20kg mass 703 and a 60 Shore hardness rubber shock-absorbing pad 702. When the tower vibrates under wind load, the mass 703, due to inertia, moves in the opposite direction of the tower's vibration. The elastic deformation and damping effect of the rubber shock-absorbing pad 702 converts the vibration energy into heat and dissipates it, significantly suppressing the tower's vibration response and reducing the risk of structural damage due to resonance.

[0028] When wind loads cause the tower to vibrate at low frequencies and high amplitude, the inertial motion of mass 703 and the cushioning effect of rubber shock-absorbing pads 702 further absorb the vibration energy. Together with the dampers, this forms a multi-stage vibration reduction system, reducing the tower's vibration amplitude and protecting the tower structure and internal equipment. Furthermore, fixing rods 704 securely connect support frame 701 to horizontal crossarm 502, ensuring that protective assembly 7 will not fall off under long-term wind vibrations, ensuring continued protection.

[0029] The anemometer 803 monitors the wind speed of the surrounding environment in real time, and the vibration sensor 804 detects the vibration amplitude and frequency of the tower in real time. When it is detected that the wind speed exceeds the set threshold or the tower vibration is abnormal, maintenance measures can be taken in time to ensure the safe operation of the communication tower.

[0030] The warning sign 902 and warning light 903 within the warning structure alert nearby personnel and equipment in severe weather or high winds, preventing accidental collisions. The solar panel 905 converts solar energy into electricity, which is stored in the battery 906 and used to power the warning light 903 and detection components 8, ensuring that the warning and monitoring functions remain functional even without an external power source. This design not only improves the safety of the communication tower but also achieves energy self-sufficiency, reducing operating costs.
