[0027] like Figure 1 and Figure 2 As shown, the embodiment of the utility model provides a wind turbine foundation reinforcement assembly 100, which includes an annular concrete beam 102 and at least one first reinforcement member 104. Specifically, during actual assembly, the annular concrete beam 102 can be sleeved and assembled on the outside of the foundation ring or steel tower 200 of the wind turbine. For the assembly of the wind turbine foundation, the foundation ring is first installed on the foundation column 202, and then the foundation ring is used as an intermediate connecting member to assemble the steel tower on the foundation ring. In other words, the assembly position of the annular concrete beam 102 can be determined according to actual conditions, and can be installed on the foundation ring or on the steel tower.

[0030] In an optional embodiment, for the annular concrete beam 102, the shape of the annular concrete beam 102 can be set to a circular ring structure, such as Figure 2 As shown. In this case, the shape of the annular concrete beam 102 can be further constructed to match the shape of the outer surface of the foundation ring or the steel tower 200 of the wind turbine. In other words, the circular ring structure of the annular concrete beam 102 and the circular ring outer surface of the foundation ring or the steel tower 200 are mutually adapted and tightly fitted, which can achieve a better reinforcement effect. It should be understood here that the circular ring structure of the annular concrete beam 102 is only one of the optional embodiments of the utility model. In other optional embodiments, the shape of the annular concrete beam 102 can also be any other shape, as long as its shape can be adapted to the shape of the outer surface of the foundation ring or the steel tower 200. The utility model is not limited to one or some specific embodiments.

Further, when multiple first reinforcements 104 are selected for reinforcement, the multiple first reinforcements 104 can be arranged around the central axis of the annular concrete beam 102. In other words, the multiple first reinforcements 104 can be arranged around the central axis of the annular concrete beam 102 at intervals and at equal intervals. In an optional embodiment, the multiple first reinforcements 104 can also be arranged parallel to each other. It should be understood that according to the above-described embodiments, by arranging multiple first reinforcements 104, the reinforcement effect can be effectively improved.
[0032] As for the assembly method of the first reinforcement member 104, in the embodiment of the present utility model, the first end of the first reinforcement member 104 can extend from the lower surface of the annular concrete beam 102 to the inside of the annular concrete beam 102 and be firmly held therein; on the other hand, the second end of the first reinforcement member 104 can extend from the upper surface of the base column 202 to the inside of the base column 202 and be firmly held therein, thereby forming a Figure 1In this embodiment, the arrangement direction of each first reinforcement member 104 can be parallel to the arrangement direction of the central axis of the annular concrete beam 102, that is, it can be extended along the height direction of the entire wind turbine foundation.
[0033] Optionally, in an embodiment of the present utility model, the specific structure of the first reinforcement member 104 can be configured as a high-strength steel bar or an anchor bolt, so as to improve the bending strength.
[0034] It should be noted that, for the first reinforcement member 104, the material, arrangement, arrangement direction, quantity and other related settings of the first reinforcement member 104 can be changed or adjusted according to the actual application. In other words, the above is only an optional exemplary implementation of the utility model, and the utility model is not limited to one or some specific implementations.
[0035] Continue to see Figure 1 and Figure 2 In the embodiment of the present utility model, the wind turbine foundation reinforcement assembly 100 may further include at least one second reinforcement member 108. Specifically, the second reinforcement member 108 may be sleeved and installed on the outer side of the annular concrete beam 102, so as to reinforce the annular concrete beam 102.
[0036] In an optional embodiment, similar to the annular concrete beam 102, the second reinforcement 108 can also be set to an annular structure, so that the shape of the second reinforcement 108 is adapted to the shape of the annular concrete beam 102, and then adapted to the shape of the foundation ring or the steel tower 200, thereby improving the reinforcement effect.
[0037] In addition, the number of the second reinforcing members 108 can also be set according to the situation, for example, only one or more second reinforcing members 108 can be used. In an optional embodiment of the utility model, when multiple second reinforcing members 108 are used, the multiple second reinforcing members 108 can be spaced apart and arranged at equal intervals along the height direction of the annular concrete beam 102, so as to form a Figure 1 In other words, the plane formed by the annular structure of each second reinforcing member 108 is perpendicular to the extension direction of the central axis of the annular concrete beam 102, and two adjacent second reinforcing members 108 are equidistant from each other and are arranged parallel to each other.
[0038] Optionally, in an embodiment of the present utility model, the specific structure of the second reinforcement member 108 can be configured as prestressed steel bars or prestressed steel strands, so as to improve the bending strength.
[0039] It should be noted here that, similar to the first reinforcement member 104, for the second reinforcement member 108, the material, arrangement mode, arrangement direction and quantity of the second reinforcement member 108 can be changed or adjusted according to the actual application. In other words, the above is only an optional exemplary implementation of the utility model, and the utility model is not limited to one or some specific implementations.

Then, a second reinforcement member 108 configured as an external prestressed steel bar or prestressed steel strand is arranged on the outside of the ring-shaped concrete beam 102 to increase the lateral pressure. Then, a first reinforcement member 104 configured as a high-strength steel bar or an anchor bolt is arranged at the lower part of the ring-shaped concrete beam 102, and the upper and lower ends of the high-strength steel bar are anchored into the ring-shaped concrete beam 102 and the foundation column 202 respectively.
[0041] In summary, the wind turbine foundation reinforcement assembly 100 provided in the embodiment of the utility model utilizes the annular concrete beam 102 and the first reinforcement member 104 to stably reinforce the foundation ring or steel tower 200 of the wind turbine and the foundation column 202 of the wind turbine, thereby improving the bending resistance of the wind turbine foundation and significantly improving the reinforcement effect. In addition, the second reinforcement member 108 configured as an external prestressed steel bar is arranged on the outer side of the annular concrete beam 102 to achieve the effect of increasing the lateral pressure. The raw materials of the embodiment of the utility model only use reinforced concrete and anchor glue, and the reinforcement cost is low. In addition, a plurality of high-strength steel bars can be arranged along the center line of the beam under the annular concrete beam 102, which has strong bending resistance and obvious reinforcement effect.
