[0002] As wind turbine power generation efficiency increases, wind turbine blades are getting longer and longer, and the height and cross-sectional dimensions of the wind turbine towers that match them are also increasing. Steel structure towers are difficult to meet the construction requirements of large-section high towers due to their high cost and difficulty in transportation. Precast concrete towers can economically build large wind turbines, and therefore have received widespread attention. Ultra-high performance concrete, referred to as UHPC, has higher strength, toughness and durability than traditional concrete materials. UHPC towers can significantly improve the stability and safety of wind turbine towers.

[0003] At present, the existing UHPC concrete tower adopts two cylinder pieces to be hoisted and combined into one tower when splicing. After the two cylinder pieces are spliced, they need to be limited and fixed by multiple sets of limit fixing parts. The splicing construction steps are relatively cumbersome, which affects the efficiency of tower assembly. Therefore, a UHPC concrete tower for wind power tower is proposed to solve the above problems. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0023] like Figure 1-4 As shown, the utility model provides a technical solution: a UHPC concrete tower for a wind power tower, comprising a first cylinder sheet 1 and a second cylinder sheet 3, the first cylinder sheet 1 is fixedly connected with a first docking block 5, the second cylinder sheet 3 is provided with a first docking groove 6, and the second cylinder sheet 3 is provided with a docking mechanism 2;

[0024] The docking mechanism 2 includes a fixed frame 201 and an adjusting block 204. A partition 202 is fixedly installed inside the fixed frame 201, and a threaded tube 203 is fixedly installed on the partition 202. The internal thread of the threaded tube 203 is connected with a threaded column 208. A bearing 206 is fixedly installed at the bottom of the adjusting block 204. The upper end of the threaded column 208 is fixedly installed on the inner wall of the inner ring of the bearing 206. A positioning column 205 is fixedly installed on the upper surface of the adjusting block 204. A positioning hole 210 is opened at the bottom of the first docking block 5, and the upper end of the positioning column 205 is inserted into the inside of the positioning hole 210.

[0025] The first docking block 5 is inserted into the first docking groove 6 . The second tube piece 3 is provided with a mounting groove 4 . The fixing frame 201 is fixedly installed in the mounting groove 4 . The setting of the mounting groove 4 can facilitate the setting of the fixing frame 201 in the second tube piece 3 .

[0026] A turning handle 209 is fixedly installed at the lower end of the threaded column 208, and a light rod 207 is fixedly installed at the bottom of the adjustment block 204. A guide hole is opened on the partition 202, and the light rod 207 passes through the inside of the guide hole. The setting of the light rod 207 can play a role of limiting and guiding the adjustment block 204.

[0027] There are two first docking blocks 5, and the two first docking blocks 5 are respectively fixedly installed on the left end and the right end of the upper surface of the first cylinder piece 1. There are two first docking grooves 6, and the two first docking grooves 6 are both opened on the second cylinder piece 3. The arrangement of the first docking blocks 5 and the first docking grooves 6 can improve the accuracy of docking between the first cylinder piece 1 and the second cylinder piece 3.

[0028] In this embodiment, after the second cylinder segment 3 is hoisted and placed in position, the first cylinder segment 1 is hoisted and spliced ​​with the second cylinder segment 3, so that the first docking block 5 on the first cylinder segment 1 falls into the first docking groove 6 on the second cylinder segment 3 for docking. After completion, the turning handle 209 is rotated to drive the threaded column 208 to move the positioning column 205 upward and insert it into the positioning hole 210 on the first docking block 5 to complete the docking assembly of the cylinder segments. If the positioning column 205 cannot be directly inserted into the positioning hole 210, it means that the two cylinder segments are not completely docked and there is a docking offset problem, which requires calibration, which is convenient for the staff to perform calibration and detection, thereby improving the efficiency of tower assembly. Example

[0029] like Figure 1-4 As shown, based on the first embodiment, the utility model provides a technical solution: a second docking groove 8 is opened at the bottom of the first cylinder sheet 1, and a U-shaped steel part 7 is fixedly installed inside the second docking groove 8. The second docking groove 8 can be reinforced by the setting of the U-shaped steel part 7.

The arrangement of the second docking groove 8 and the second docking block 9 can further improve the accuracy of the docking between the first cylinder piece 1 and the second cylinder piece 3.

[0031] In this embodiment, by providing the second docking groove 8 and the second docking block 9, the firmness and stability of the docking between the first cylinder segment 1 and the second cylinder segment 3 can be further improved, making the tower splicing more stable. At the same time, the provision of the rubber seal 10 can improve the sealing of the two cylinder segments after direct splicing, further improving the practicality of the tower.

[0032] When in use, after the second cylinder piece 3 is hoisted and placed in position, the first cylinder piece 1 is hoisted and assembled with the first cylinder piece 1 and the second cylinder piece 3, so that the first docking block 5 on the first cylinder piece 1 falls into the first docking groove 6 on the second cylinder piece 3 for docking. After completion, the turning handle 209 is turned to drive the threaded column 208 to move the positioning column 205 upward and insert it into the positioning hole 210 on the first docking block 5 to complete the docking assembly of the cylinder pieces. If the positioning column 205 cannot be directly inserted into the positioning hole 210, it means that the two cylinder pieces are not completely docked and there is a docking offset problem. Calibration is required to facilitate the calibration and detection of the staff, thereby improving the efficiency of tower assembly. By setting the second docking groove 8 and the second docking block 9, the firmness and stability of the docking between the first cylinder piece 1 and the second cylinder piece 3 can be further improved, making the tower splicing more stable. At the same time, the setting of the rubber seal 10 can improve the sealing of the two cylinder pieces after direct splicing, thereby further improving the practicality of the tower.
