Description

Technical Field

[0001] This utility model relates to the field of tower tube segment technology, specifically to a prefabricated earthquake-resistant concrete tower tube segment. Background Technology

[0002] Wind turbines with a power generation capacity of 10 kilowatts or less are generally referred to as small wind turbines. Small wind turbines mainly consist of the following parts: wind turbine, generator, rotating body, speed regulation mechanism, directional adjustment mechanism, braking mechanism, and tower. In recent years, my country's wind power generation industry has made great progress and development. Faced with fierce market competition, key indicators such as long blades and large megawatts are constantly being refreshed. Meanwhile, concrete-steel hybrid towers have advantages such as high reliability, anti-resonance, low cost, good waterproofness, good durability, low maintenance cost, stable power generation, and increased power generation, and are being increasingly used in practice.

[0003] The diversity of concrete wind turbine tower segment forms gives the tower structure great flexibility and adaptability. It can not only meet the special requirements of the project for tower size, shape, materials, etc., but also be designed in a targeted manner according to local climate conditions, topography and other factors, so as to ensure the safe and efficient operation of wind power projects.

[0004] Chinese patent CN221400788U discloses an earthquake-resistant concrete tower segment. Through the combined use of auxiliary and internal components, the device has high seismic resistance and stability, making it suitable for harsh environments such as storms and heavy rain, and possessing a certain degree of earthquake resistance. The device also adopts a prefabricated structural design, and the support rods have a storage function, facilitating transportation and reducing transportation costs.

[0005] Although the above scheme improves the structural strength of the assembled tube segments by adding auxiliary components to the outside of the tube segments, since most towers are assembled by stacking tower segments longitudinally, the auxiliary components at the top are difficult to bear the force, resulting in limited structural strength of the assembled tower. Furthermore, the tube segments are assembled by relying solely on bolts for connection, which results in poor load-bearing capacity.

[0006] Therefore, this utility model provides a prefabricated earthquake-resistant concrete tower segment to solve the above problems. Utility Model Content

[0007] In order to overcome the shortcomings of the prior art, this utility model provides a prefabricated earthquake-resistant concrete tower segment to solve the problems that most towers are composed of tower segments stacked longitudinally, and the auxiliary components at the top are difficult to bear the force, resulting in limited structural strength of the assembled tower. In addition, the segments are assembled by relying only on bolts to complete the connection, which results in poor load-bearing capacity.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A prefabricated seismic-resistant concrete tower segment includes a segment body and connectors. Connecting blocks are fixedly connected to both sides of the segment body, and each connecting block has a connecting groove. The two ends of the connector are respectively inserted into the two connecting grooves. A protruding strip is fixedly connected to the upper surface of the segment body, and a positioning groove matching the protruding strip is opened on the bottom surface of the segment body.

[0010] Preferably, the inner wall of the connecting groove is provided with a locking bolt, the locking bolt has an internal threaded connection to a threaded hole, and one end of the threaded hole is inserted into the connector.

[0011] Preferably, the cross-section of the connecting groove is T-shaped, and the cross-section of the connector is I-shaped.

[0012] Preferably, the segment body has an arc-shaped through hole and an installation groove that communicates with the arc-shaped through hole. An arc-shaped bolt is provided in the arc-shaped through hole, and one end of the arc-shaped bolt passes through the arc-shaped through hole and extends into the installation groove.

[0013] Preferably, a limiting block is fixedly connected to the convex strip, and a limiting groove adapted to the limiting block is provided on the positioning groove.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The combination of connectors and connecting blocks makes the connection between adjacent segments more stable, which not only improves the structural strength of individual segments, but also significantly enhances the seismic performance of the entire tower, enabling it to remain stable in harsh environments such as storms and even earthquakes, thus ensuring the long-term safe operation of wind power projects.

[0016] 2. By setting up convex strips, positioning grooves, and corresponding limiting blocks and grooves, the problem of insufficient load-bearing capacity caused by traditional tube segments relying solely on bolt connections is effectively solved. This not only ensures that the longitudinally arranged tube segments can be tightly connected, but also strengthens the fixation between adjacent transverse tube segments, thereby significantly improving the stability and load-bearing capacity of the overall tower structure.

[0022] The following will refer to the attached reference. Figures 1 to 4 The various embodiments of this utility model will be described in detail below. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this utility model and are not intended to limit the scope of protection of this utility model.

[0023] A prefabricated seismic-resistant concrete tower segment includes a segment body 1 and connectors 11. Connecting blocks 4 are fixedly connected to both sides of the segment body 1. The connecting blocks 4 are located on the side at the port of the segment body 1, and the side of the connecting blocks 4 is flush with the assembly surface of the segment body 1. When two segment bodies 1 are assembled laterally, the sides of the two connecting blocks 4 that are close to each other are pressed against each other. Each connecting block 4 has a connecting groove 5. The two ends of the connector 11 are respectively inserted into the two connecting grooves 5. The connection of the two connecting blocks 4 is completed by inserting the connector 11 into the connecting groove 5.

[0024] The inner wall of the connecting groove 5 is provided with a locking bolt 13, and the locking bolt 13 is internally threaded with a threaded hole 12. One end of the threaded hole 12 is inserted into the connector 11. The connecting groove 5 can be a connected groove or a non-connected groove. When a connected groove is selected, the worker needs to lean against the bottom end of the connecting groove 5 to limit the connector 11 placed in the connecting groove 5. When a non-connected groove is selected, after the connector 11 is inserted into the connecting groove 5 from the top, the bottom end of the connector 11 is leaned against the inner bottom wall of the connecting groove 5.

[0025] After the connector 11 is installed in place, the threaded hole 12 is threaded into the locking bolt 13. The connector 11 has a hole that matches the threaded hole 12. The threaded hole 12 is used to fix the connector 11 in the connecting block 4. That is, the connector 11 and the two connecting blocks 4 are used to limit the transverse adjacent tube body 1.

[0026] The cross-section of the connecting groove 5 is T-shaped, and the cross-section of the connector 11 is I-shaped. Since the connecting groove 5 is T-shaped, when adjacent connecting grooves 5 are spliced ​​together, they will form an I-shape to match the connector 11.

[0027] Among them, the segment body 1 has an arc-shaped through hole 2, and the segment body 1 has an installation groove 3 that communicates with the arc-shaped through hole 2. An arc-shaped bolt 10 is provided in the arc-shaped through hole 2, and one end of the arc-shaped bolt 10 passes through the arc-shaped through hole 2 and extends into the installation groove 3.

[0028] The arc-shaped perforation 2 is located between two longitudinally arranged connecting blocks 4. When assembling the transversely arranged tube body 1, the two arc-shaped perforations 2 will be connected. Then, the two ends of the connector 11 are respectively placed in the two arc-shaped bolts 10, and the connector 11 is locked by installing nuts in the mounting groove 3, thereby completing the fixation of the two tube body 1.

[0029] The upper surface of the segment body 1 is fixedly connected with a protruding strip 8, and the bottom surface of the segment body 1 is provided with a positioning groove 6 that matches the protruding strip 8. When splicing the longitudinally arranged segment bodies 1, the protruding strip 8 needs to be inserted into the positioning groove 6.

[0030] A limiting block 9 is fixedly connected to the protruding strip 8. A limiting groove 7 adapted to the limiting block 9 is opened on the positioning groove 6. After the protruding strip 8 is inserted into the positioning groove 6, the tube body 1 above the tube body 1 is continuously lowered, which will insert the upper limiting block 9 of the lower tube body 1 into the upper limiting groove 7. Thus, the connection of the longitudinally arranged tube body 1 is completed by using the protruding strip 8 and the limiting block 9, thereby improving the stability of the tower.

[0031] By setting up convex strips, positioning grooves, and corresponding limiting blocks and grooves, the problem of insufficient load-bearing capacity caused by traditional tube segments relying solely on bolt connections is effectively solved. This not only ensures that the longitudinally arranged tube segments can be tightly connected, but also strengthens the fixation between adjacent transverse tube segments, thereby significantly improving the stability and load-bearing capacity of the overall tower structure.
