Description
Technical Field
[0001] This invention relates to the field of power generation tower foundation technology, and in particular to a foundation for an offshore wind power generation tower. Background Technology
[0002] Offshore wind power towers are important facilities for generating electricity in marine environments. They are typically used to capture offshore wind energy and convert it into electricity. Compared with onshore wind power generation, offshore wind power generation has advantages such as abundant wind energy resources and more stable wind speeds. The foundation of an offshore wind power tower must be able to withstand external forces such as the tower's own weight, wind loads, and ice and snow loads. After the foundation is built, it needs to be monitored and maintained regularly to ensure its long-term stability and safety.
[0003] Offshore wind turbine towers typically have two types of foundations: fixed foundations and floating foundations. Fixed foundations are generally suitable for shallower waters, while floating foundations are generally suitable for deeper waters. However, regardless of the type, the erosion caused by the marine environment will affect the foundation of the offshore wind turbine tower over time, thus affecting its actual service life. Moreover, the installation of offshore wind turbine towers is usually quite complicated, as changes in weather, waves, and tides can significantly impact construction. Therefore, it is necessary to address these issues. Summary of the Invention
[0004] Based on the technical problems existing in the background technology, the present invention proposes a foundation for offshore wind power generation towers.
[0005] This invention proposes a foundation for an offshore wind power tower, comprising a base, a second support column fixedly connected to the center of the top of the base, a second fixing ring sleeved on the surface of the second support column, a first connecting seat disposed at the center of the top of the base, the first connecting seat slidably sleeved on the surface of the second support column, a support seat disposed on the top of the first connecting seat, the support seat being vertically disposed, a plurality of protective plates disposed on the surface of the support seat, a connecting mechanism connecting the first connecting seat to the top of the base, and an installation mechanism for installing the plurality of protective plates inside the support seat. The plurality of protective plates can be fitted to the surface of the support seat during use, thereby achieving a protective effect on the surface of the support seat. Furthermore, the horizontal sliding of the protective plates facilitates replacement or maintenance of the protective plates during use, thus improving the effectiveness of the device.
[0006] Preferably, the connecting mechanism includes a second connecting seat. A plurality of first connecting columns are fixedly connected to the top of the base. All first connecting columns are vertically arranged and evenly distributed in a ring. A first fixing ring is fitted onto the surface of each of the first connecting columns. Multiple second connecting seats are provided, each slidingly fitted onto the surface of one of the first connecting columns. A second flange is fixedly connected to the bottom of each of the second connecting seats. The second flanges are respectively disposed on the top of the first fixing rings. Fixing bolts are installed inside each of the second flanges, and each fixing bolt cooperates with one of the first fixing rings, facilitating the installation of the first connecting seats and thus improving the ease of installation of the device.
[0007] Furthermore, a plurality of first cross braces are horizontally fixedly connected to the surface of the first connecting seat. The plurality of first cross braces are respectively fixedly connected to the surface of a plurality of second connecting seats at one end away from each other. Each surface of the first connecting seat is fixedly connected to a diagonal brace. The plurality of diagonal braces are all inclined. The lower end of the plurality of diagonal braces is respectively fixedly connected to the surface of a plurality of second connecting seats. The same second cross brace is horizontally fixedly connected between two adjacent second connecting seats. A first flange is fixedly connected to the top of the first connecting seat. A third flange is fixedly connected to the bottom of the support seat. The third flange mates with the first flange. The third flange is installed on the top of the first flange to connect the first connecting seat and the plurality of second connecting seats, thereby improving the stability of the first connecting seat.
[0008] Preferably, the mounting mechanism includes multiple sliding plates, each horizontally slidably connected to the inside of a support base. Each sliding plate is vertically positioned, and two sliding rods are horizontally fixedly connected to the surface of each sliding plate. The support base has multiple connecting holes on its surface, and the sliding rods are slidably fitted into these holes. A fixing plate is fixedly connected to one end of each sliding rod. Two connecting sleeves are vertically slidably connected at the center of the support base. Each connecting sleeve has multiple connecting grooves on its surface, and a pull rod is hinged into each groove. The pull rods are paired in pairs. A fixing strip is vertically fixedly connected to the side of each sliding plate away from the sliding rods. Each pair of pull rods... The rod is hinged to the upper and lower ends of the fixed strip. A lead screw is rotatably connected to the center of the support base. The lead screw is vertically arranged, and its top end is rotatably sleeved on the top of the support base. Two sliders are slidably sleeved on the surface of the lead screw, and both sliders cooperate with the surface of the lead screw. The two sliders are connected to the lead screw in opposite directions. Two connecting sleeves are respectively sleeved on the outer surfaces of the two sliders. A fixed base is fixedly connected to the top of the support base, and a motor is installed inside the fixed base. The output end of the motor is fixedly connected to the top of the lead screw to restrict the vertical sliding of the two lead screws, thereby allowing multiple sliding plates to slide closer or further apart. At the same time, multiple protective plates will also slide, thus facilitating the protection of the support base surface.
[0009] Furthermore, each of the protective plates has two vertically formed grooves on one side near the support base, each groove has a mounting hole at its bottom, and each groove has a limiting groove inside. Each fixing piece is slidably connected to each mounting hole and limiting groove, and each sliding rod is slidably connected to each groove for installing the protective plate, thereby facilitating maintenance of the protective plate during use.
[0010] In this invention, the multiple protective plates can be fitted to the surface of the support base during use, thereby achieving a protective effect on the surface of the support base. At the same time, the horizontal sliding of the protective plates facilitates the replacement or maintenance of the protective plates during use, thereby improving the protective effect of the device.
[0011] The device is easier to install due to the first connecting seat, and with the addition of multiple second connecting seats, the device is more stable during use through the connection of multiple diagonal braces, first horizontal braces, and second horizontal braces, thereby improving the device's convenience and stability.

[0024] Reference Figure 4 and Figure 5In a preferred embodiment, the mounting mechanism includes multiple sliding plates 7, each horizontally slidably connected to the inside of a support base 5. Each sliding plate 7 is vertically arranged, and two sliding rods 71 are horizontally fixedly connected to the surface of each sliding plate 7. The support base 5 has multiple connecting holes 52 on its surface, and the sliding rods 71 are slidably fitted into the connecting holes 52. A fixing piece 72 is fixedly connected to one end of each sliding rod 71. Two connecting sleeves 63 are vertically slidably connected at the center of the support base 5. Multiple connecting grooves 64 are provided on the surface of each connecting sleeve 63, and a pull rod 74 is hinged inside each connecting groove 64. The pull rods 74 are paired in pairs. A fixing strip 73 is vertically fixedly connected to the side of each sliding plate 7 away from the sliding rods 71. The two ends of the pull rod 74 are respectively hinged to the upper and lower ends of the fixed strip 73. A lead screw 6 is rotatably connected to the center of the support base 5. The lead screw 6 is vertically set, and the top end of the lead screw 6 is rotatably sleeved on the top of the support base 5. Two sliders 62 are slidably sleeved on the surface of the lead screw 6. The two sliders 62 are connected to the lead screw 6 in opposite directions. Two connecting sleeves 63 are respectively sleeved on the outer surface of the two sliders 62. A fixed base 3 is fixedly connected to the top of the support base 5. A motor 61 is installed inside the fixed base 3. The output end of the motor 61 is fixedly connected to the top of the lead screw 6 to restrict the two lead screws 6 from sliding up and down, so that multiple sliding plates 7 slide closer or further away from each other. At the same time, multiple protective plates 4 will slide, which facilitates the protection of the surface of the support base 5.
[0025] Reference Figure 6 and Figure 7 In a preferred embodiment, each protective plate 4 has two vertically formed grooves 42 on one side near the support base 5.

[0026] In this invention, the multiple protective plates 4, when in actual use, can adhere to the surface of the support base 5, thereby achieving a protective effect on the surface of the support base 5. Simultaneously, the horizontal sliding of the protective plates 4 facilitates replacement or maintenance during use, thus improving the effectiveness of the device. During use, the motor 61 inside the drive base 3 rotates the lead screw 6. At this time, the connection of the two sliders 62 causes the two connecting sleeves 63 to slide closer or further apart. Simultaneously, the connection of the multiple pull rods 74 causes the multiple sliding plates 7 to slide closer or further apart. Furthermore, with the connection of multiple sliding rods 71 and fixing plates 72, multiple protective plates 4 will slide closer to each other or further away from each other on the surface of the support base 5. When multiple protective plates 4 slide closer to each other, they will fit against the surface of the support base 5, thus facilitating the protection of the surface of the support base 5. When multiple protective plates 4 move away from the surface of the support base 5, they can be easily disassembled. By lifting the protective plate 4 upward, multiple fixing plates 72 can slide out of the mounting hole 41 through the limiting groove 43, thus allowing the protective plate 4 to be quickly removed, facilitating the maintenance or replacement of the protective plate 4, thereby improving the protective effect of the device.
