A plurality of circumferential steel bars 3 laid along the trend of the plurality of top radial steel bars 4. A limiting component 5 arranged between two adjacent radial steel bars 2 to evenly distribute the plurality of radial steel bars 2 and fix the plurality of radial steel bars 2 together. And a binding component 6 arranged on the plurality of circumferential steel bars 3 to quickly bind the circumferential steel bars 3 to the adjacent top radial steel bars 4 / radial steel bars 2 and top radial steel bars 4 together.

The limiting piece one 51 and the limiting piece two 52 are in mutual contact, which can automatically and evenly lay the plurality of radial steel bars 2 when laying the radial steel bars 2, without manual positioning, reducing the labor intensity of the staff. At the same time, the uniform laying of the radial steel bars 2 can also make the base of the wind turbine more stable and firm.

[0030] Furthermore, the limiting piece one 51 includes a connecting rod one 511 arranged on both sides of the butt joint steel bar one 21; the other ends of the connecting rod one 511 are both connected with a butt joint plate one 512; a sleeve 513 is connected to the butt joint plate one 512; a sliding column 514 is slidably connected to the lower opening of the sleeve 513; an adjusting inclined surface one is arranged at the lower end of the sliding column 514; a spring one 515 is connected between the sleeve 513 and the sliding column 514; the limiting piece two 52 includes a connecting rod two 521 arranged on both sides of the butt joint steel bar two 22; the other ends of the connecting rod two 521 are both connected with a butt joint plate two 522; a limiting column 523 which is matched and clamped with the sliding column 514 is connected to the butt joint plate two 522. The plurality of radial steel bars 2 can be firmly connected together, avoiding the sliding and dislocation of the radial steel bars 2 in the subsequent construction process, thus increasing the construction difficulty.

[0031] Embodiment 2

[0032] As Figures 6-8As shown in the figure, a base of a wind turbine generator set proposed by the present utility model further includes, compared with the first embodiment: multiple groups of binding assemblies 6 are evenly arranged on each circumferential steel bar 3, and the multiple groups of binding assemblies 6 respectively correspond to the multiple radial steel bars 2 and the multiple top-layer radial steel bars 4 one by one. The binding assembly 6 includes a connecting member 61 arranged on the circumferential steel bar 3 and a binding member 62 arranged on the connecting member 61 for binding the circumferential steel bar 3 to the adjacent top-layer radial steel bar 4 / radial steel bar 2 and the top-layer radial steel bar 4. The connecting member 61 includes a base 611 arranged on the circumferential steel bar 3; both ends of the base 611 are connected with connecting plates 614; the binding member 62 includes a binding belt 621 rotatably connected at one end to one of the connecting plates 614; a slot 622 is opened at the other end of the binding belt 621; a limit box 623 is arranged on the other connecting plate 614; a through slot 624 is opened at the upper end of the limit box 623, and a second spring 625 is connected to the inner wall; the other end of the second spring 625 is connected with a plug board 626 that cooperates with and is clamped in the slot 622; an adjusting inclined surface two is arranged at the upper end of the plug board 626; the binding belt 621 binds the circumferential steel bar 3 and the top-layer radial steel bar 4 together through the cooperation and clamping of the slot 622 and the plug board 626. The circumferential steel bar 3 and the adjacent top-layer radial steel bar 4 can be bound together, and the binding can be completed while laying the circumferential steel bar 3 and the top-layer radial steel bar 4. The binding is convenient and fast, which can greatly improve the construction efficiency of the wind turbine base, and the binding is firm and not easy to fall off.

[0033] Further explanation, two groups of binding members 6 are arranged crosswise on the connecting member 61. Further strengthen the firmness of the binding, so that the connection between the circumferential steel bar 3 and the top-layer radial steel bar 4 is not easy to loosen.

[0034] Further explanation, multiple groups of sliding grooves 612 corresponding to the binding assemblies 6 one by one are opened on the circumferential steel bar 3; the base 611 is slidably connected at the corresponding sliding grooves 612. When the placement positions of the radial steel bar 2 or the top-layer radial steel bar 4 are not accurately aligned with the binding assembly 6, the base 611 can be slid to make their positions opposite to each other, which is convenient for binding.

[0035] Further explanation, the lower end of the base 611 arranged on the circumferential steel bar 3 below the top-layer radial steel bar 4 is connected with an elastic gripper 613 that cooperates with and is clamped to the radial steel bar 2. Pressing down the circumferential steel bar 3 can make the radial steel bar 2 be clamped into the elastic gripper 613, completing the connection between the radial steel bar 2 and the circumferential steel bar 3. The connection is fast, convenient, time-saving and labor-saving.

[0036] The working principle of the utility model is as follows: When building the base, first insert multiple anchor rods 1 vertically in a circular shape, and then insert multiple radial steel bars 2 one by one into the gaps between two adjacent anchor rods 1, so that the docking plate one 512 and the docking plate two 522 are in mutual contact, thereby enabling the automatic equidistant laying of multiple radial steel bars 2 without manual positioning, reducing the labor intensity of the staff. When laying the radial steel bars 2, first place the docking steel bar one 21, and then place the docking steel bar two 22. After the limiting column 523 abuts against the first adjusting inclined surface provided on the sliding column 514, push the sliding column 514 upward into the sleeve 513 to compress the first spring 515. Subsequently, the first spring 515 resets to drive the sliding column 514 to rebound downward, and the limiting column 523 is limited between the docking plate one 512 and the sliding column 514, realizing the fixed connection between the docking steel bar one 21 and the docking steel bar two 22. Subsequently, lay a layer of circumferential steel bars 3, press the circumferential steel bars 3 downward so that the elastic gripper 613 catches the radial steel bars 2. Then lay the top-layer radial steel bars 4, rotate the binding band 621 to extend one end of the binding band 621 into the through groove 624, and make the binding band 621 press the second adjusting inclined surface provided on the plug board 626, so that the second spring 625 retracts. Subsequently, the second spring 625 resets to drive the plug board 626 to be inserted into the slot 622, thereby binding the circumferential steel bars 3 and the top-layer radial steel bars 4 together, realizing the fixed connection between the circumferential steel bars 3 and the top-layer radial steel bars 4. Then lay another layer of circumferential steel bars 3 outside the top-layer radial steel bars 4 and repeat the above steps. Finally, surround the outside of the device with steel plates and pour concrete to complete the installation of the wind turbine base.

[0037] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited thereto. Various changes can be made without departing from the gist of the present utility model within the scope of knowledge possessed by those skilled in the art to which it pertains.
