[0002] With the rapid development of wind power technology, the height and scale of wind turbine generators are constantly increasing, especially the application of hybrid tower (hybrid tower) structures in the wind power field. Hybrid tower structures are typically composed of concrete and steel sections, possessing high strength and stability, effectively supporting the operation of large wind turbine generators. However, the connection between the prefabricated tower sections of hybrid tower structures has always been one of the technical challenges.

[0003] In existing wind turbine hybrid tower structures, prefabricated tower sections are typically connected by bolts or welding. While bolted connections are convenient to install, they are susceptible to wind loads and vibrations during long-term operation, leading to bolt loosening and affecting the stability and safety of the structure. Welded connections, on the other hand, provide strong connection strength, but the welding process is complex, and welding quality is difficult to guarantee, making welding defects more likely. Furthermore, welding is time-consuming and labor-intensive, affecting the efficiency of equipment installation and making it difficult to quickly fix and install prefabricated tower sections of wind turbine hybrid towers. In addition, the welded structure is difficult to disassemble and maintain, increasing the difficulty and cost of later maintenance.

[0004] To address the problems raised in the background art, those skilled in the art have proposed a prefabricated tower section connection structure for wind power hybrid towers. Summary of the Invention

Detailed Implementation

[0018] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0019] Example 1: As shown in the attached document Figure 1 To be continued Figure 4 As shown: The present invention provides a prefabricated tower section connection structure for wind power hybrid towers, including a structural component 100, comprising a structural member 101, a fixing member 102 disposed on one side of the structural member 101, a clamping member 103 disposed on the inner side of the structural member 101, an auxiliary member 104 disposed on one side of the structural member 101, and a positioning member 105 disposed on one side of the structural member 101; The structural component 101 includes a first connecting plate 101a and a second connecting plate 101b, which are Z-shaped. The structural component 101 also includes a connecting sleeve 101c disposed on the side wall of the first connecting plate 101a and the second connecting plate 101b, which is used to install reinforcing bars. The fastener 102 includes an insert block 102a fixedly installed on the side wall of the first connecting plate 101a, a side wall mounting groove 102b opened in the insert block 102a, a wedge block 102c slidably disposed on the side wall of the mounting groove 102b, and a compression spring 102d disposed inside the mounting groove 102b. The two ends of the compression spring 102d are respectively connected to the side wall of the wedge block 102c and the side wall of the mounting groove 102b. The fastener 102 also includes a mounting block 102e fixedly mounted on the side wall of the second connecting plate 101b, a slot 102f formed in the side wall of the mounting block 102e, a screw 102g threaded into the slot 102f, a locking plate 102h rotatably disposed on one side of the screw 102g, and a locking block 102i disposed on one side of the locking plate 102h. The insert block 102a is inserted into the slot 102f and slidably disposed therewith. During installation, the insert block 102a is inserted into the slot 102f on the side wall of the mounting block 102e. During the insertion process, the inclined surface of the locking block 102i first contacts the inclined surface of the wedge block 102c. When the wedge 102c is pressed inward into the mounting groove 102b, the insert 102a can be inserted inward. When the insert 102a is fully inserted into the end point and needs to be pulled out, the wedge 102c is driven to return to its original position by the rebound force of the compression spring 102d. This causes the wedge 102c to re-enter the tooth groove of the locking block 102i. At this time, the vertical part of the wedge 102c contacts the vertical part of the locking block 102i, thereby locking the wedge 102c and the insert 102a, making it impossible for the insert 102a to be pulled out, thus achieving the locking and fixing of the insert 102a.

[0020] Preferably, the positioning component 105 includes a positioning rod 105a fixedly installed on one side of the first connecting plate 101a and a positioning hole 105b opened on one side of the mounting block 102e. The positioning rod 105a is inserted into the positioning hole 105b and slidably disposed therewith. The positioning rod 105a and the positioning hole 105b can be used to position the device during installation, thereby improving the installation efficiency of the device.

[0021] As can be seen from the above, during installation, the positioning rod 105a on the side wall of the first connecting plate 101a is inserted into the positioning hole 105b on the side wall of the second connecting plate 101b. During insertion, the insert block 102a is inserted into the slot 102f on the side wall of the mounting block 102e. At this time, the inclined surface of the locking block 102i first contacts the inclined surface of the wedge block 102c, pressing the wedge block 102c inward into the mounting groove 102b so that the insert block 102a can be inserted inward. When the insert block 102a... When the insert 102a is fully inserted into the end point and needs to be pulled out, the wedge 102c is driven to return to its original position by the rebound force of the compression spring 102d. This causes the wedge 102c to re-enter the tooth groove of the locking block 102i. At this time, the vertical part of the wedge 102c contacts the vertical part of the locking block 102i, thereby locking the wedge 102c and the insert 102a, making it impossible for the insert 102a to be pulled out, thus achieving the locking and fixing of the insert 102a.

[0022] Example 2: As shown in the attached document Figure 2 To be continued Figure 5 As shown: This embodiment is basically the same as the previous embodiment, except that the clamping member 103 includes an inner cavity 103a opened on one side of the mounting block 102e, a slide rod 103b slidably disposed in the inner cavity 103a, a trapezoidal block 103c fixedly installed on one side of the slide rod 103b, and a groove 103d opened on the side wall of the insertion block 102a. The trapezoidal block 103c is inserted into the groove 103d and slidably disposed therewith. During the insertion process, the insertion block 102a first contacts the inclined surface of the trapezoidal block 103c, and slides and squeezes the trapezoidal block 103c to both sides, so that the insertion block 102a can continue to be inserted inward.

[0023] Preferably, the clamping member 103 further includes a rotating plate 103e rotatably disposed within the inner cavity 103a, a return spring 103f disposed on one side of the inner cavity 103a, and a limiting groove 103g formed on one side of the rotating plate 103e. During the process of the insert block 102a sliding inward, the trapezoidal block 103c sliding in the groove will cause the rotating plate to rotate slightly within the inner cavity 103a, thereby squeezing the return spring 103f. When sliding to the end point, the trapezoidal block 103c corresponds to the groove 103d formed on the side wall of the insert block 102a. At this time, the rotating plate 103e is driven by the rebound force of the return spring 103f to return and slide within the inner cavity 103a. Since the trapezoidal block 103c will continue to be at the groove on the side wall of the inner cavity 103a and the slot 102f, During the reset rotation of the rotating plate 103e, the trapezoidal block 103c will be reset and slid due to the limitation of the slot, so that it is inserted into the groove 103d, thereby achieving auxiliary clamping and fixing of the insert 102a. When it is necessary to pull out the insert 102a, the horizontal surface of the trapezoidal block 103c contacts the side wall of the groove 103d to perform auxiliary locking and fixing, thereby improving the locking and fixing effect of the insert 102a. One end of the slide rod 103b is fixedly installed with a limiting plate 103h, which extends into the limiting groove 103g and slides therewith. The radius of the outlet of the limiting groove 103g is smaller than the radius of the limiting plate 103h. This setting facilitates the limiting treatment and reduces the possibility of the trapezoidal block 103c falling off.

[0024] Furthermore, the structural component 101 also includes an inspection door 101d on the side wall of the second connecting plate 101b. The inspection door 101d can be quickly opened when disassembly and maintenance are required, and the locking plate 102h and the rotating plate 103e inside can be manually adjusted to release the locking of the insert block 102a, thereby allowing the first connecting block and the second connecting block to be quickly disassembled.

[0025] As can be seen from the above, during the installation process, the insert 102a first contacts the inclined surface of the trapezoidal block 103c, causing the trapezoidal block 103c to slide and press to both sides. When the trapezoidal block 103c slides in the slot, it will cause the rotating plate to rotate slightly in the inner cavity 103a, thereby squeezing the return spring 103f. When it slides to the end point, the trapezoidal block 103c corresponds to the groove 103d on the side wall of the insert 102a. At this time, the rotating plate 103e is driven by the rebound force of the return spring 103f to move inside. The trapezoidal block 103c slides back and forth within the cavity 103a. Since the trapezoidal block 103c will remain at the groove between the inner cavity 103a and the side wall of the slot 102f, it will be limited by the groove. During the reset rotation of the rotating plate 103e, the trapezoidal block 103c will be driven to slide back and forth, so that it is inserted into the groove 103d, thereby achieving auxiliary clamping and fixing of the insert 102a. When it is necessary to pull out the insert 102a, the horizontal surface of the trapezoidal block 103c contacts the side wall of the groove 103d to perform auxiliary locking and fixing.

[0026] Example 3: As shown in the attached document Figure 1 To be continued Figure 7 As shown: Based on Embodiment 2, the auxiliary component 104 includes a plug rod 104a fixedly installed on one side of the first connecting plate 101a and a fixing sleeve 104b fixedly installed on one side of the second connecting plate 101b. The plug rod 104a is inserted into the fixing sleeve 104b and slidably disposed therewith. When the plug block 102a on the side wall of the first connecting block is inserted into the slot 102f opened in the mounting block 102e on the side wall of the second connecting block, the plug rod 104a is also inserted into the fixing sleeve 104b on the side wall of the second connecting plate 101b, thereby improving the stability of the installation.

[0027] Specifically, the auxiliary component 104 also includes channels 104c formed on both sides of the insertion rod 104a, a locking block 104d slidably disposed in the channel 104c, and a first spring 104e disposed inside the channel 104c. The auxiliary component 104 also includes a through hole 104f formed on the peripheral side of the fixed sleeve 104b. The locking block 104d extends into the through hole 104f and is slidably disposed therewith. When the insertion rod 104a is inserted into the fixed sleeve 104b, in the initial state, the locking block 104d is pressed into place by the pressure of the inner wall of the fixed sleeve 104b. Inside the channel 104c, when the insertion rod 104a is inserted to the end position inside the fixed sleeve 104b, the locking block 104d corresponds to the through hole 104f opened on the side wall of the fixed sleeve 104b. At this time, the locking block 104d is driven by the rebound force of the first spring 104e to slide towards the through hole 104f, so that it is inserted into the through hole 104f, thereby realizing the fixed installation of the insertion rod 104a, thereby realizing the auxiliary fixed installation of the first connecting plate 101a and the second connecting plate 101b, and improving the stability of the installation.

[0028] Furthermore, the auxiliary component 104 also includes a fixing plate fixedly installed in the through hole 104f, a push rod 104h slidably disposed on one side of the fixing plate, and an arc-shaped pressing block 104i fixedly installed on one end of the push rod 104h. When the insertion rod 104a is inserted into the fixed sleeve 104b, the push rod 104h is pressed upward by the locking block 104d, causing the arc-shaped pressing block 104i on the push rod 104h to re-extrude from the through hole 104f. The auxiliary component 104 also includes an annular pressing plate 104j slidably disposed on the outside of the fixed sleeve 104b and a tension spring 104k disposed on one side of the second connecting plate 101b. The two ends of the tension spring 104k are respectively connected to the side wall of the annular pressing plate 104j and the second connecting plate 101b. The side wall is connected, and the annular extrusion plate 104j contacts the arc-shaped extrusion block 104i. When it is necessary to disassemble the insertion rod 104a, the annular extrusion plate 104j is pulled, and the annular extrusion plate 104j slides outside the fixed sleeve 104b. When it slides to the arc-shaped extrusion block 104i, it extrudes the arc-shaped extrusion block 104i, thereby driving the top rod 104h to slide downward. The extrusion block 104d presses it into the groove 104c, thereby releasing the clamping and fixing of the insertion rod 104a. At this time, the insertion rod 104a can be pulled out directly for quick disassembly. At this time, the annular extrusion plate 104j is released, and the annular extrusion plate 104j is driven to reset and slide by the rebound force of the tension spring 104k for the next fixed installation.

[0029] As can be seen from the above, during the installation process, when the insert 102a on the side wall of the first connecting block is inserted into the slot 102f opened in the mounting block 102e on the side wall of the second connecting block, the insert rod 104a is also inserted into the fixing sleeve 104b on the side wall of the second connecting plate 101b. When the insert rod 104a is inserted to the end position inside the fixing sleeve 104b, the locking block 104d corresponds to the through hole 104f opened in the side wall of the fixing sleeve 104b. At this time, the locking block 104d is driven by the rebound force of the first spring 104e to slide towards the through hole 104f, so that it is inserted into the through hole 104f, thereby realizing the fixed installation of the insert rod 104a, thus realizing the auxiliary fixed installation of the first connecting plate 101a and the second connecting plate 101b, and improving the stability of the installation.

[0030] When it is necessary to disassemble the insertion rod 104a, pull the annular compression plate 104j. The annular compression plate 104j slides outside the fixed sleeve 104b. When it slides to the arc-shaped compression block 104i, it compresses the arc-shaped compression block 104i, thereby driving the top rod 104h to slide downward. The compression locking block 104d presses it into the groove 104c, thereby releasing the clamping and fixing of the insertion rod 104a. At this time, the insertion rod 104a can be pulled out directly for quick disassembly. Then, the annular compression plate 104j is released. The annular compression plate 104j is driven to reset and slide by the rebound force of the tension spring 104k, for the next fixing and installation.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
