[0034] Figure 4 for Figure 3 BB sectional view. Among them, such as Figure 4 As shown, the first drive assembly 2 includes a bidirectional screw 21, a guide rod 22, and a pair of bearing plates 23. The bidirectional screw 21 and the guide rod 22 are arranged parallel to each other in the first cavity 11. Each bearing plate 23 has a through hole and a threaded hole. The bearing plate 23 is slidably fitted onto the guide rod 22 through the through hole. The bearing plate 23 is connected to the bidirectional screw 21 through the threaded hole. The two bearing plates 23 are respectively connected to the forward thread and the reverse thread of the bidirectional screw 21. A transverse cone rod 3 is connected to the opposite sides of the pair of bearing plates 23. Rotating the bidirectional screw 21 can drive the pair of bearing plates 23 to slide opposite sides along the guide rod 22, thereby causing the transverse cone rod 3 to extend out of the first cavity 11 and insert into the soil layer in the foundation pit.

[0035] In this embodiment, as Figure 4 As shown, one end of the transverse cone rod 3 is connected to the bearing strip 23, and the other end of the transverse cone rod 3 is a pointed tip, which is inserted into the through hole on the side of the bearing platform 1. When the bidirectional screw 21 is rotated, it can drive a pair of bearing strips 23 to slide along the guide rod 22 in a direction away from each other, thereby driving the transverse cone rod 3 to extend out of the through hole on the side of the bearing platform 1 and insert into the soil layer in the foundation pit.

[0036] The first driving assembly 2 in this embodiment includes a bidirectional screw 21, a guide rod 22, and a pair of bearing plates 23. The bidirectional screw 21, also called a double-ended bolt, double-ended stud, or double-ended threaded rod, has threads at both ends and a smooth shaft in the middle; the threads at both ends are forward and reverse threads, respectively. One bearing plate 23 is slidably fitted onto the guide rod 22 through a through hole on one side, and connected to the forward thread of the bidirectional screw 21 through a threaded hole on the other side. The other bearing plate 23 is slidably fitted onto the guide rod 22 through a through hole on one side, and connected to the reverse thread of the bidirectional screw 21 through a threaded hole on the other side. By rotating the bidirectional screw 21, the pair of bearing plates 23 can be driven to move away from each other along the guide rod 22, thereby pushing the transverse cone rod 3 out of the side wall of the bearing platform 1 and inserting it into the soil layer on the side of the pit, thus improving the stability, bearing capacity, and anti-displacement ability of the bearing platform 1.

[0037] Among them, see Figure 4 The transverse tapered rod 3 and the supporting strip plate 23 are connected by welding. In this embodiment, the transverse tapered rod 3 and the supporting strip plate 23 are connected by welding, which facilitates assembly and ensures the connection strength between the transverse tapered rod 3 and the supporting strip plate 23.

[0038] Among them, such as Figure 4 As shown, one end of the bidirectional screw 21 extends out of the first cavity 11 and is connected to the rotating disk 24.

[0039] In this embodiment, a rotating disk 24 is provided at one end of the bidirectional screw 21 that extends out of the first cavity 11. The rotating disk 24 can be connected to the drive device through a rotating chain or transmission belt, so as to drive the bidirectional screw 21 to rotate and enable the transverse cone rod 3 to be smoothly inserted into the soil layer.

[0040] Figure 5 for Figure 2 CC section view. Among them, such as Figure 5 As shown, the second drive assembly 6 includes a pair of slide rods 61, a pair of support plates 62, and a pair of push screws 63. The pair of slide rods 61 are arranged parallel to each other in the second cavity 41. The pair of support plates 62 are slidably mounted on the pair of slide rods 61. The rod portion of each push screw 63 passes through the side wall of the pressure plate 4 and is rotatably connected to a support plate 62. The push screw 63 is threadedly connected to the side wall of the pressure plate 4. A pair of arc-shaped guard plates 7 are respectively connected to opposite sides of the pair of support plates 62. Rotating the head of the push screw 63 can push the support plate 62 to move along the slide rods 61 toward the outer casing 5, thereby causing the arc-shaped guard plates 7 to abut against the outer circumferential surface of the outer casing 5.

[0041] In this embodiment, as Figure 5 As shown, the inner wall curvature of the arc-shaped guard plate 7 is adapted to the outer peripheral surface of the outer casing 5, and a pair of arc-shaped guard plates 7 symmetrically surround the outer peripheral surface of the outer casing 5.

[0042] The second drive assembly 6 in this embodiment includes a pair of sliding rods 61, a pair of support plates 62, and a pair of push screws 63. Each arc-shaped protective plate 7 is disposed on the side of a support plate 62 facing the outer casing 5. Each push screw 63 extends from the side of the pressure plate 4 into the second cavity 41 and is connected to the support plate 23. Rotating the push screw 63 causes it to rotate into the second cavity 41, thereby pushing the support plate 62 towards the outer casing 5 until the arc-shaped protective plate 7 wraps around the outer casing 5. Under the cooperative support of the connecting cylinder 12 and the arc-shaped protective plate 7, the outer casing 5 is more stable, facilitating the installation of the wind turbine tower and making the wind turbine tower more stable.

[0043] Among them, such as Figure 5 As shown, a positioning sleeve 64 is provided on the support plate 62. The rod of the push screw 63 passes through the side wall of the pressure plate 4 and is rotatably inserted into the positioning sleeve 64.

[0044] In this embodiment, a positioning sleeve 64 is provided on the support plate 62, and the push screw 63 is inserted into the positioning sleeve 64, which enables the push screw 63 to stably push the arc-shaped guard plate 7 to move.

[0045] Among them, see Figure 5The arc-shaped guard plate 7 and the support strip plate 62 are connected by welding. In this embodiment, the arc-shaped guard plate 7 and the support strip plate 62 are connected by welding, which facilitates assembly and ensures the connection strength between the arc-shaped guard plate 7 and the support strip plate 62.

[0046] Among them, such as Figure 1 As shown, the bearing platform 1 also includes a vertical cone rod 13. The vertical cone rod 13 is located at the bottom of the bearing platform 1. The vertical cone rod 13 is used to insert into the soil layer below the bearing platform 1.

[0047] In this embodiment, the support platform 1 is provided with a vertical cone rod 13 at the bottom. When the support platform 1 is placed at the bottom of the foundation pit, the vertical cone rod 13 can be inserted into the soil layer at the bottom of the foundation pit, which improves the stability of the support platform 1.

[0048] Among them, such as Figure 1 As shown, the pressure plate 4 is provided with an observation window 44. The observation window 44 corresponds to the second drive component 6.

[0049] In this embodiment, as Figure 1 As shown, the observation window 44 can be designed with a cutout or covered with tempered glass.

[0050] In this embodiment, an observation window 44 is provided on the pressure plate, which allows observation of the second drive component 6 and facilitates the assembly of the push screw 63 and the support plate 62.

[0051] The base for a wind turbine in this embodiment has been described in detail above. However, it should also be noted that both the support platform 1 and the pressure plate 4 in this embodiment adopt a box-type structure, with a first cavity 11 and a second cavity 41 inside, respectively. To facilitate the installation of the reinforcement unit and the anti-deviation unit, at least one side of the support platform 1 and the pressure plate 4 is designed to be open. After the reinforcement unit and the anti-deviation unit are installed, that side of the plate is then closed. Furthermore, the base for a wind turbine in this embodiment can be prefabricated. In the production workshop, the reinforcement unit is first assembled in the support platform 1, and the second drive assembly 6 of the anti-deviation unit is assembled in the pressure plate 4, before being transported to the wind turbine installation site. At the wind turbine installation site, the support platform 1, connecting cylinder 12, pressure plate 4, arc-shaped protective plate 7, and outer protective cylinder 5 are assembled according to the base construction sequence to form the base.
