[0036] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0037] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.
[0039] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components are required to be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.
[0040] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0041] In one aspect, the utility model provides a spigot-and-socket concrete tower for wind power generation, comprising a plurality of interconnected concrete tower pipe sections 1;
[0042] The mixing tower pipe section 1 includes a concrete structure 3 arranged inside the mixing tower pipe section 1 and a structural steel bar 2 located inside the concrete structure 3;
[0043] One end of the mixing tower pipe section 1 is provided with a socket 11, and the other end is provided with an inserting platform 12 matching the socket 11.
[0044] A concrete structure 3 is arranged inside the mixed tower pipe section 1 to prevent the concrete structure 3 from being corroded and reducing its firmness. A structural steel bar 2 is arranged inside the concrete structure 3 to further improve the mechanical properties of the concrete structure, thereby improving the firmness of the mixed tower pipe section 1 as a whole. When the mixed tower pipe section 1 is hoisted, the inserting platform 12 can be embedded in the adjacent pipe section bearing groove 11, and the inserting platform 12 is connected to the bearing groove 11 in a spigot-and-socket manner. It can be quickly aligned and installed, and rainwater can be prevented from penetrating from the transverse seam of the pipe section connection, and the sliding dislocation of the mixed tower pipe section during the operation of the fan can be avoided, which greatly improves safety and is highly practical.
[0045] In some specific implementations, the inner diameter L2 of one end of the mixing tower pipe segment 1 provided with the socket 11 is ≥ the inner diameter L1 of the inserting platform 12 provided on the mixing tower pipe segment 1 .
[0046] When in use, the mixed tower pipe segment 1 with L1=L2 and the mixed tower pipe segment 1 with L2≥L1 can be mixed and used to gradually reduce the diameter of the concrete tower. The mixed tower pipe segment 1 with L1=L2 or the mixed tower pipe segment 1 with L2≥L1 can also be used continuously as needed.
[0047] In some specific implementations, the socket 11 and the insert 12 are both coaxially arranged with the mixing tower pipe section 1 .
[0048] It ensures that when the socket 11 and the insert 12 complete the socket-and-spigot connection, they are symmetrically balanced at all angles, thereby improving firmness.
[0049] In some specific embodiments, the depth H1 of the socket 11 is 2-5 mm greater than the depth H2 of the inserting platform 12. When the socket 11 and the inserting platform 12 are connected in a socket-and-spigot manner, the socket 11 can better support the inserting platform 12 to prevent the inserting platform 12 from being separated from the socket 11 due to external forces. The optimal depth is 3 mm.
[0050] In some specific embodiments, the angle β1 between the side wall and the bottom of the socket 11 is 5° to 15° greater than the angle β2 between the outer wall of the insert 12 and the end face of the mixing tower pipe segment 1. When the socket 11 and the insert 12 are connected in a spigot-and-socket manner, the angle β1 between the side wall and the bottom of the socket 11 can better accommodate the angle β2 between the outer wall of the insert 12 and the end face of the mixing tower pipe segment 1, further avoiding the danger of the insert 12 being separated from the socket 11 due to external forces. The most preferred angle is 15°.
[0051] In some specific embodiments, the width ts1 of the bottom of the socket 11 is 2-3 mm greater than the width tb1 of the top of the insert 12. Combining β1-β2=15° and H1-H2=3 mm, the firmness of the socket connection can be further improved. The most preferred value is 2 mm.
[0052] In some specific embodiments, the depth H1 of the socket 11 is 15 to 20 mm;
[0053] The angle β1 between the side wall and the bottom of the socket 11 is greater than 90°;
[0054] The depth H2 of the inserting platform 12 is 12-17 mm;
[0055] The included angle β2 between the outer wall of the inserting platform 12 and the end surface of the mixing tower pipe section 1 is greater than 90°.
[0056] In some specific implementations, the socket 11, the insert 12 and the mixing tower pipe section 1 are an integrated structure.
[0057] In some specific embodiments, the mixing tower pipe segment 1 is an integrated cylindrical structure, or a cylindrical structure assembled from multiple pieces.
[0058] When the mixing tower pipe section 1 is a cylindrical structure assembled from multiple pieces, it can be divided into several pieces along the central axis, and the several pieces are sequentially connected and assembled into a cylindrical structure.
[0059] According to another aspect of the utility model, there is also provided an assembled concrete tower for wind power generation, which is composed of the aforementioned socket-and-spigot concrete tower for wind power generation and a steel tower section 4 located at the upper end of the socket-and-spigot concrete tower for wind power generation.
[0060] By using the socket-type concrete tower for wind power generation, it has a higher degree of firmness; it can be quickly aligned and installed, and prevents rainwater from seeping in from the transverse joints of the pipe joints. It can also avoid sliding and dislocation of the concrete tower pipe joints during the operation of the wind turbine, greatly improving safety and strong practicality.
