Description

Technical Field

[0001] The invention relates to the technical field of combined wind power towers, in particular to a combined wind power tower frame prestressed concrete and steel tower section connection transition device. Background Art

[0002] A combined wind turbine tower is a wind turbine tower composed of a prestressed concrete tower section and a steel tower section. Prestressed concrete tower sections usually have high compressive strength and good durability, while steel tower sections have high tensile strength and good flexibility. By combining these two materials, their respective advantages can be fully utilized to improve the overall performance of the wind turbine tower.

[0003] According to the patent document: CN104018724A, a combined wind power tower prestressed concrete tower section and steel tower section connection device is disclosed, and the steel connection member is composed of an upper end connection flange, a connection steel cylinder section, a connection anchor flange, two cylindrical anchor steel plates, a stiffening connection steel plate and a steel anchor bolt, and each part forms a whole. The vertical prestress is applied to the concrete tower section by a prestressing component. The upper end of the prestressed steel strand or prestressed anchor bolt is anchored to the upper surface of the connection anchor flange after being tensioned by the post-tensioning method. The stiffening connection steel plate and the steel anchor bolt are embedded in the concrete. The stiffness of the connection section is increased by stiffening the connection steel plate, so that the stress distribution at the top of the concrete tower section is uniform. The present invention can ensure that the internal space of the tower is not reduced due to the thick wall thickness of the concrete tower, which is of great significance to improving the unevenness of the stress distribution at the connection of the combined tower, effectively controlling the crack width of the concrete tower section, and improving the durability and fatigue resistance of the combined tower.

[0004] In the existing wind power tower design, the connection structure between the prestressed concrete tower section and the steel tower section is traditionally realized by bolt connection or welding technology. However, these traditional connection methods have exposed several significant problems in practical applications. Specifically, although bolt connection is widely used, it is easy to loosen after long-term service. When the bolt is subjected to tension, it will indirectly cause the concrete tower tube to be subjected to shear force, which in turn causes the problem of uneven force distribution on the tower tube. On the other hand, although welding connection can achieve strong connection strength, fatigue cracks are easy to occur in the welding parts during long-term service, affecting the durability of the overall structure. In addition, it is worth noting that the bottom of the wind turbine tower often adopts a hollow design inside the tower to optimize the structural weight and performance. When relying solely on bolt connections and welding methods, it is difficult to ensure the stability of the tower under complex wind loads. The continuous action of wind loads will cause the tower to continuously bear alternating tensile and compressive stresses, which will pose a severe test to its crack resistance and fatigue resistance. Summary of the invention

[0005] The purpose of the present invention is to provide a combined wind power tower prestressed concrete and steel tower section connection transition device to solve the problem that the bolt connection proposed in the prior art is prone to loosening after long-term service. When the bolt is subjected to tension, it will indirectly cause the concrete tower to be subjected to shear force, thereby causing the problem of uneven force distribution on the tower. On the other hand, although the welding connection can achieve a strong connection strength, fatigue cracks are prone to occur at the welding part during long-term service, affecting the durability of the overall structure. The interior of the tower body at the bottom of the wind power tower often adopts a hollow design to optimize the structural weight and performance. When relying solely on bolt connection and welding methods, it is difficult to ensure the stability of the tower under complex wind loads. The continuous action of wind loads will cause the tower to continuously bear alternating tension and compression stresses, thereby posing a severe test to its crack resistance and fatigue resistance.

[0023] Working principle: when it is necessary to support the inside of the tower, the motor 313 is first started, and the rotation of the motor is transmitted to the rotating rod 316 through the conical teeth 314 and the second conical teeth 315, so that the rotating rod rotates, and the top end of the rotating rod extends to the outer wall of the base 311, driving the control panel top plate 325 on the top of the multiple control panel bodies 321 to rotate, and the control panel top plate 325 rotates accordingly, and the sliding connection of the arc groove 326 and the top slide bar 328 causes the push rod 3210 and the slider 327 in the control panel body 321 to produce corresponding displacement. As the multiple control panel top plates 325 rotate, the multiple bottom slide bars 329 slide in the slide groove 324, pushing the multiple push rods 3210 and the arc support plates 3211 to move to one side, and then the multiple arc support plates 3211 expand and support the inner wall of the tower.

The multiple moving plates 333 move and then mesh with the gears 416 hinged to the inner wall of the multiple reinforcement mechanism chassis 411 through the rack 334 at the top, so that the multiple gears 416 rotate and drive the rotating pressure rod slider 418 on one side of the outer wall to rotate. The rotating rod 417 rotates to change the angle and drives the rotating pressure rod slider 418 on the other side to slide on the inner wall of the slide plate 422, thereby pushing the pressure rod body 421 to rotate on the inner wall of the hinge groove 414, so that the pressure rod body 421 rotates outward, and finally realizes the connection reinforcement support of the second-stage tower and the bottom tower, and gives a certain pressure to the second-stage tower and the bottom tower through the pressure rod body 421, so that they are firmly connected to the top of the embedded part 1. In this way, the entire support mechanism can effectively reinforce the tower to ensure the stability and safety of its structure. When it is necessary to adjust the position of the internal support mechanism 3 and the second-order tower body reinforcement mechanism 4 on the inner wall of the tower so as to reinforce it more firmly, the hydraulic push rod 27 can perform telescopic movement to push the connecting cross bar 26 to move forward or backward. The movement of the connecting cross bar 26 drives the articulated rod 24 to rotate around the articulated slider 23, and then the second articulated slider 25 slides in the base slide groove 312, thereby changing the angle between the two sets of articulated rods 24 and pushing the internal support mechanism 3 and the second-order tower body reinforcement mechanism 4 to rise and fall on the inner wall of the tower. In this way, the control base 2 can realize precise position adjustment of the internal support mechanism 3 and the second-order tower body reinforcement mechanism 4 to ensure that they can be reinforced at the required position on the inner wall of the tower.
