DETAILED DESCRIPTION

[0031] Example 1

[0032] Figure 1 This is a pre-buried foundation for wind power construction proposed by the utility model. The structural shape and size ratio in the figure are for reference only.

[0033] The embedded base structure includes a base 1, a support column 2, and a drilling device 3. The base 1 and the support column 1 are both cylindrical. The support column 2 is installed above the base 1. There are multiple drilling devices 3, which are positioned and installed through positioning holes 15 arranged at equal intervals in the circumferential direction of the base 1.

[0034] like Figure 2 , Figure 3 As shown, each drilling device 3 includes a column 11, a threaded rod 12, a propulsion device 13, and a conical rod 14. The column 11 passes through the middle of the positioning hole 15, and the threaded rod 12 is longitudinally installed in the middle of the column 11 with the top exposed. There are two conical rods 14, and the two conical rods 14 are symmetrically arranged in the horizontal direction. The side of the column 11 is provided with an entry and exit hole 16 for facilitating the entry and exit of the tip of the conical rod 14. A propulsion device installation groove 17 is provided inside the column 11 for installing the propulsion device 13 and the conical rod 14. The propulsion device 13 is installed between the threaded rod 12 and the conical rod 14, and its function is to convert the longitudinal rotation in or out of the threaded rod 12 into the lateral rotation in or out of the conical rod 14.

[0035] The specific structure of the propulsion device 13 and the connection parts with the threaded rod 12 is as follows:

[0036] A support member 101 is provided at the rear end of the threaded rod 12, and the support member 101 is hinged to two support rods 102, and the other ends of the support rods 102 are each hinged to a support frame 107, and a rack 103 is transversely fixedly installed on the plug column 11 at a position above the support frame 107, and the gear 104 and the rack 103 form a gear rack mechanism. A groove 108 for installing the first bevel gear 105, the second bevel gear 106 and the gear 103 is provided on the support frame 107, and the first bevel gear 105 is coaxially installed with the gear 104. The second bevel gear 106 is installed at the axial center of the conical rod 14, and the horizontal first bevel gear 105 and the longitudinal second bevel gear 106 mesh with each other at a vertical angle. When the threaded rod 12 is screwed in, the support frame 107 moves horizontally, the gear 104 and the rack 103 engage to produce horizontal rotation, and the first bevel gear 105 synchronized with the gear 104 engages with the second bevel gear 106, converting the horizontal rotation into the longitudinal screwing of the conical rod 14, so that the conical rod 14 passes through the entry and exit hole 16 and enters the underground soil layer. On the contrary, when the threaded rod 12 is screwed out, the conical rod 14 retreats, leaves the soil layer and returns to the inside of the plug.

[0037] like Figure 4 As shown, in order to fix the column 11 and control the depth of the column 11 buried in the ground, the base of this embodiment is also provided with a limiting ring 18 at the top of the base 1, and the limiting ring 18 is provided with a threaded ring 112. The inner side of the top of the column 11 is provided with a threaded groove 120 corresponding to the threaded ring 112, and the actual burial depth of the column 11 is controlled by screwing the threaded ring 112 on the limiting ring 18 in and out.

[0038] In order to maintain the stability of the threaded rod 12 during the lifting process, the base of this embodiment is further provided with a limit rod 109, a slider 110, and a slide groove 111. The slide groove 111 is provided on the inner wall of the plug column 11, and its length is set corresponding to the lifting height of the threaded rod 12. The slider 110 is installed in the slide groove 111, and the two ends of the limit rod 109 are respectively connected to the support member 101 and the slider 110. When the threaded rod 12 is lifted and lowered, the limit rod 109 plays a role in ensuring that the threaded rod 12 does not tilt longitudinally.

[0039] like Figure 5 , Figure 6As shown, in order to control the travel distance of the conical rod 14 when it enters the soil layer and maintain the stability of the conical rod 14 when it moves, the base of this embodiment is also provided with a convex block 113, a convex block mounting groove 114 and a first spring 115. The convex block mounting groove 114 is installed in the plug column 11 and extends to the inner wall of the plug column 11. The convex block 113 is arranged in the convex block mounting groove 114 and is connected to the bottom of the support frame 107. The first spring 115 is arranged between the convex block 113 and the inner wall of the plug column 11. When the conical rod 14 is screwed into the soil layer, the support frame 107 slides in the convex block mounting groove 114 driven by the convex block 113 to keep the conical rod 14 moving smoothly. The first spring 115 controls the depth of the conical rod 14 screwed into the soil layer.

[0040] Example 2

[0041] like Figure 7 , Figure 8 As shown, in order to protect the embedded base 1 and support column 2, the base of this embodiment is also provided with a protection device 4.

[0042] The protection device 4 includes a fixing sleeve 116 , a bracket 117 , a railing 118 and a second spring 119 .

[0043] The fixing sleeve 116 is composed of two semicircular annular sleeves, which are integrally sleeved on the support column 2. A plurality of brackets 117 are evenly spaced and connected to the outside of the fixing sleeve 116. The other end of each bracket 117 is connected to a railing 118 via a second spring 119. When there is an external impact, the railing 118 bears the impact force, and the second spring 119 absorbs the impact energy to protect the support column 2 and the base 1 thereunder.

[0044] The wind power civil engineering pre-buried foundation provided by the utility model adopts the method of sequentially passing a plurality of plug posts 11 through a plurality of positioning holes 15 in the body of the foundation 1, so that one end of the plug posts 11 is inserted into the ground, and then the threaded rod 12 inside the plug posts 11 is rotated, and the two support rods 102 at the bottom of the lower end support member 101 are respectively connected with the rotation of the two support frames 107, so as to push the two support frames 107 to move laterally, and the conical rods 14 on one side of the two support frames 107 are respectively passed through the inlet and outlet holes 16 on both sides of the plug posts 11 and inserted into the soil, and since the gear 104 at the top of the support frame 107 is meshed with the rack 103 inside the plug posts, the gear 104 rotates with the movement of the support frame 107, and the first bevel gear 105 and the second bevel gear 106 are meshed, and the first bevel gear 105 and the second bevel gear 106 are respectively fixedly connected with the conical rod 14 and the gear 104, the gear 104 drives the conical rod 14 to rotate, and the soil is drilled. After the fixing of the plug posts 11 is completed, the threaded rings 112 at the bottom of the plurality of limit rings 18 are aligned with the threaded grooves 120 at the tops of the plurality of plug posts 11 in sequence, and the limit rings 18 are installed on the plurality of plug posts 11 by rotation to limit the position of the base 1 body. Similarly, when the base 1 needs to be disassembled, the plurality of limit rings 18 are rotated in the reverse direction to separate the limit rings 18 from the plug posts 11, and the threaded rods 12 are screwed out in the reverse direction to make the conical rods 14 leave the soil layer and be retracted into the plug posts 11, so that the base 1 can be separated from the plurality of plug posts 11. According to the needs, the fixing sleeve 116 can be sleeved on the support column, so that the plurality of brackets 117 and railings 118 outside the fixing sleeve 116 surround the base 1 and the support column 2 to protect the base 1 and the support column 2.
