Description

Technical Field

[0001] This utility model relates to the field of bridge tower structure technology, and in particular to a wind-resistant bridge tower that can generate electricity. Background Technology

[0002] Composite bridge towers are a common structural form in modern bridge engineering, combining the advantages of both steel and concrete to achieve higher structural performance and economy. A composite bridge tower refers to a bridge tower structure that uses a combination of steel and concrete. This structure typically consists of a steel frame (outer or inner shell) and concrete filling the frame. This combination utilizes both the high tensile strength and good ductility of steel and the high compressive strength and good durability of concrete.

[0003] The loads exerted by wind on bridge structures can be enormous, especially on tall bridge towers. These loads include static wind loads and dynamic wind loads, the latter of which can cause structural vibrations. Wind-induced vibrations can lead to structural fatigue damage. Therefore, wind-resistant structures are required on composite bridge towers. Utility Model Content

[0026] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] Example 1, as Figures 1 to 5 As shown, this application proposes a wind-resistant bridge tower capable of generating electricity, comprising two combined bridge towers 1. A crossbeam 2 is fixedly installed between two adjacent combined bridge towers 1. The crossbeam 2 has a square steel tube cross-section and connects the two combined bridge towers 1, making the two combined bridge towers 1 form a whole to jointly resist wind loads. Each combined bridge tower 1 includes a steel outer shell 101 and a steel inner shell 102 located inside the steel outer shell 101. The steel outer shell 101 and the steel inner shell 102 are fixedly connected by anchor bolts 5. The steel outer shell 101, as the external structure of the combined bridge tower 1, mainly bears lateral loads, such as wind loads and seismic forces, and has good tensile strength and ductility. The steel inner shell 102, as the internal skeleton, provides longitudinal and lateral support and also serves as a formwork for pouring concrete 103. The steel inner shell 102 is typically smaller than the steel outer shell 101 to save materials.

[0028] Furthermore, concrete 103 is poured between the steel outer shell 101 and the steel inner shell 102, with the outer shell 101 being thicker than the inner shell 102. Reinforcing bars are arranged both longitudinally and transversely within the concrete 103. A reinforcing cage is installed within the concrete 103; similarly, when filling the inner shell 102 with concrete, a reinforcing cage is typically placed within the inner shell to increase the tensile and shear strength of the concrete. Since the concrete 103 is poured inside the inner shell, its compactness and quality must be ensured to fully utilize its high compressive strength. Anchor bolts 5 are used to connect the steel outer shell 101 and the inner shell 102, providing additional structural stiffness and stability.

[0029] Furthermore, the inner steel shell 102 is made of rectangular square tube, and the outer steel shell 101 is made of irregular square tube. The outer steel shell 101 has a chamfer 104 on the windward side.

[0030] This embodiment also includes a vent 3 fixedly installed on the composite bridge tower 1. The vent 3 consists of two steel plates 301 connected to the windward side of the composite bridge tower 1 and fitted with the chamfer 104 on the steel shell 101. The vent 3 is an important component in bridge design for improving aerodynamic characteristics, reducing wind-induced vibration, and enhancing structural stability. When the transverse wind blows across the composite bridge tower 1, it is dispersed by the vent 3, significantly reducing the static wind load on the side of the composite bridge tower 1. After being dispersed by the vent 3, the transverse wind forms a high-pressure zone in the middle of the two composite bridge towers 1, creating wind from the middle to both sides.

[0031] Wind power generation devices 4 are fixedly installed on both sides of the combined bridge tower 1. The wind power generation devices 4 are installed inside the combined bridge tower 1 and perpendicular to it. Each wind power generation device 4 includes blades, a shaft, and a generator. The blades are the key component for capturing wind energy and typically employ an airfoil design to improve wind energy conversion efficiency. The shaft connects the blades and the generator and bears the torque generated by the blades. The generator converts wind energy into electrical energy; it can be a DC-to-AC generator or an AC generator (the wind power generation device 4 is existing technology and will not be described in detail here). The cross-bridge wind, dispersed by the nozzles 3, forms a high-voltage zone in the middle of the two combined bridge towers 1, creating wind flowing from the middle to both sides, which drives the wind power generation devices 4 to generate electricity. The longitudinal wind, flowing from both sides to the middle, directly acts on the wind power generation devices 4 to generate electricity.

[0032] Working principle: When the wind blows across the bridge in the transverse direction, it is dispersed by the wind nozzles 3, which greatly reduces the static wind load on the side of the bridge tower 1. The bridge tower 1 adopts a steel-concrete composite section with high lateral stiffness, which reduces the wind-induced vibration effect of the tower. The crossbeam 2 connects the two bridge towers 1, so that the two bridge towers 1 form a whole to jointly resist the wind load. After the wind is dispersed by the wind nozzles 3, a high-pressure zone is formed in the middle of the two bridge towers 1, which generates wind from the middle to both sides, driving the wind power generation device 4 to generate electricity. The wind along the bridge direction is from both sides to the middle, which directly acts on the wind power generation device 4 and can drive the wind power generation device 4 to generate electricity.

[0033] Example 2, as Figures 5 to 7 As shown, based on Embodiment 1, the anchor rod 5 includes a connecting rod 501, with a first thread 502 on the connecting rod 501, and two fastening nuts 503 threaded onto the first thread 502. By fixing both ends of the anchor rod 5 to the steel outer shell 101 and the steel inner shell 102 respectively, the steel outer shell 101 and the steel inner shell 102 can be fixedly connected by the anchor rod 5. After the steel inner shell 102 is fixedly connected to one end of the anchor rod 5, rotating the fastening nuts 503 can fix the anchor rod 5 onto the steel outer shell 101 and the steel inner shell 102. The steel outer shell 101 and the steel inner shell 102 are provided with connecting holes for the anchor rod 5 to pass through.

[0034] Furthermore, the end of the anchor rod 5 is equipped with a diameter-changing component, which adjusts the diameter of one end of the anchor rod 5. Since one end of the anchor rod 5 needs to pass through the steel outer shell 101 and the steel inner shell 102 and enter the interior of the steel inner shell 102, it is inconvenient to fix the anchor rod 5 to the steel inner shell 102. By setting the diameter-changing component, the anchor rod 5 can be expanded after passing through the connection hole on the steel inner shell 102, so that the expanded anchor rod 5 cannot pass through the connection hole on the steel inner shell 102, thereby facilitating the fixation of the steel inner shell 102 and the anchor rod 5.

[0035] The variable diameter assembly includes an adjusting rod 504 installed inside the connecting rod 501. The adjusting rod 504 is provided with a second thread 509 and is threadedly connected to the connecting rod 501 through the second thread 509. A bolt head 510 is fixedly installed on the adjusting rod 504. A connecting plate 505 is rotatably installed on the adjusting rod 504. Multiple first connecting rods 506 are rotatably installed on the connecting plate 505. A connecting block 507 is rotatably installed on the first connecting rod 506. A second connecting rod 508 is rotatably installed on the connecting block 507 and is rotatably connected to the connecting rod 501. After one end of the anchor rod 5 is passed through the connecting hole of the steel inner shell 102, the bolt head 510 is rotated to drive the adjusting rod 504 to rotate. Under the action of the second thread 509 and the connecting rod 501 being threaded together, the adjusting rod 504 will move along its axis, which will in turn drive the connecting plate 505 rotatably connected to it to move. When the connecting plate 505 moves closer to the connecting rod 501, it will drive multiple first connecting rods 506 to rotate. Under the action of the connecting block 507, the second connecting rod 508 will rotate synchronously. Under the action of the second connecting rod 508 and the first connecting rod 506, the connecting block 507 will expand outward, which can effectively increase the diameter of the end of the anchor rod 5, making it impossible for the end of the anchor rod 5 to pass through the connecting hole on the steel inner shell 102, thus making it easier for the anchor rod 5 to be fixedly connected to the steel inner shell 102.

[0036] The working principle of this embodiment is as follows: After one end of the anchor rod 5 passes through the connecting hole of the steel inner shell 102, rotating the bolt head 510 drives the adjusting rod 504 to rotate. Under the action of the second thread 509 and the connecting rod 501 being threaded together, the adjusting rod 504 will move along its axis, which in turn drives the connecting plate 505 rotatably connected to it to move. When the connecting plate 505 moves closer to the connecting rod 501, under the action of the second connecting rod 508 and the first connecting rod 506, the connecting block 507 will expand outward, which can effectively increase the diameter of the end of the anchor rod 5, making it impossible for the end of the anchor rod 5 to pass through the connecting hole on the steel inner shell 102, thus making it easier for the anchor rod 5 to be fixedly connected to the steel inner shell 102. Then, rotating the fastening nut 503 can fix the anchor rod 5 to the steel outer shell 101 and the steel inner shell 102.

[0037] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
