Description

Technical Field

[0001] This utility model relates to the field of concrete pole technology, and in particular to prestressed reinforced concrete poles for wind farms. Background Technology

[0002] Wind farm reinforced concrete poles are high-strength structures specifically designed for wind farm transmission lines. Utilizing prestressed reinforced concrete, they provide superior wind, bending, and torsional resistance through bottom fixing components, a ring-shaped array of supports, and internal reinforcing ribs. Wind farms are typically located in areas with strong winds and complex environments (such as coastal or mountainous regions), where traditional poles struggle to meet the demands for high strength, durability, and stability. Using prestressed reinforced concrete poles not only allows them to withstand the high wind loads and line tensions of wind farms but also reduces maintenance costs through corrosion resistance, ensuring the long-term safe operation of the transmission system and thus becoming a crucial support structure for wind farm power transmission.

[0003] Traditional wind farm prestressed reinforced concrete poles are made of high-strength concrete and prestressed steel bars. Prestressing technology enhances their bending, compressive, and tensile strength. Their simple structure typically relies on a single column design and foundation fixing method to bear wind loads and line tension, meeting the basic power transmission requirements of most wind farms. However, due to the lack of complex multi-point support and reinforcement structures, their stability and durability in extreme environments (such as strong winds and highly corrosive areas) are limited, easily leading to increased maintenance costs and reduced safety during long-term use.

[0004] Traditional reinforced concrete poles typically employ a single-column upright design, relying solely on the foundation at the bottom to withstand wind loads, line tension, and other external forces, making them ineffective in dealing with strong wind conditions in wind farms. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a prestressed reinforced concrete pole for wind farms, which aims to improve the problem that traditional reinforced concrete poles are difficult to effectively cope with strong wind conditions in wind farms.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a prestressed reinforced concrete pole for wind farms, comprising a reinforced concrete column, a fixing component at the bottom of the reinforced concrete column for fixing the column, a rotating shaft I fixedly connected to the upper side of the outer wall of the reinforced concrete column, an inclined support rotatably connected to the outer wall of the rotating shaft I, a rotating shaft II rotatably connected to one end of the inclined support, a fixing base plate fixedly connected to the lower surface of the rotating shaft II, a fixing bolt II provided inside the fixing base plate, and a support component provided on the outer wall of the inclined support, the support component cooperating with the inclined support to support the reinforced concrete column;

[0007] The support assembly includes a connecting column and a supporting column. One end of the connecting column is rotatably connected to the upper side of the outer wall of the inclined support column, and the other end of the connecting column is fixedly connected to the outer wall of the reinforced concrete column. One end of the supporting column is rotatably connected to the lower side of the outer wall of the inclined support column, and the other end of the supporting column is fixedly connected to the bottom of the reinforced concrete column.

[0008] Furthermore, the fixing component includes a base, the outer wall of which is fixedly connected to the bottom of the reinforced concrete column, and a plurality of fixing bolts are provided at the bottom of the reinforced concrete column.

[0009] Furthermore, a positioning seat is slidably connected to the top of the reinforced concrete column, a reinforced concrete composite column is fixedly connected to the upper surface of the positioning seat, an electric pole is fixedly connected to the upper surface of the reinforced concrete composite column, reinforcing ribs are fixedly connected inside the reinforced concrete column, and a connecting component is provided inside the positioning seat for connecting and fixing the reinforced concrete column and the positioning seat.

[0010] Furthermore, the connecting assembly includes a screw rod, the outer wall of which is slidably connected to the interior of the reinforced concrete column and the positioning seat, and both ends of the screw rod are threaded with nuts.

[0011] Furthermore, the inclined support columns are arranged in a circular array around the reinforced concrete column, and the inclined support columns are used to support and reinforce the reinforced concrete column.

[0012] Furthermore, the connecting column is positioned above the supporting column, and the connecting column, supporting column, inclined support column, and reinforced concrete column form two triangular support structures.

[0013] Furthermore, the reinforcing rib is slidably connected inside the positioning seat, and the reinforcing rib is used to strengthen the reinforced concrete column and the reinforced concrete composite column.

[0014] Furthermore, one side of the outer wall of the nut is attached to the outer wall of the positioning seat, and the nut is used to fix the screw inside the reinforced concrete column and the positioning seat.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, a pair of reinforced concrete columns are first fixed by the base and fixing bolts. Then, the inclined support column is pulled to provide support for the reinforced concrete column in conjunction with the first and second rotating shafts, the fixed base plate and the second fixing bolt. Finally, the supporting effect is further strengthened by the connecting column and the support column. This solves the problem of not being able to effectively cope with the strong wind conditions in the wind farm, and achieves the ability to better withstand high wind loads, reduce the possibility of tilting and swaying, thereby improving the wind resistance performance of the overall structure.

[0017] 2. In this utility model, the reinforced concrete column and the reinforced concrete composite column are first positioned by the positioning seat, and then the reinforced concrete column and the reinforced concrete composite column are further strengthened by the reinforcing ribs. Finally, the connection between the reinforced concrete column and the reinforced concrete composite column is fixed with screws and nuts. This allows it to be disassembled into multiple parts, which is suitable for long-distance transportation, especially in mountainous areas, complex terrain or remote areas of wind farms, solving the problem of difficult transportation of traditional integral poles.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 and Figure 2 An embodiment of this utility model provides a prestressed reinforced concrete pole for wind farms, comprising a reinforced concrete column 1, a fixing component at the bottom of the reinforced concrete column 1 for fixing the reinforced concrete column 1, a rotating shaft 4 fixedly connected to the upper side of the outer wall of the reinforced concrete column 1, an inclined support column 5 rotatably connected to the outer wall of the rotating shaft 4, a rotating shaft 6 rotatably connected to one end of the inclined support column 5, a fixing base plate 7 fixedly connected to the lower surface of the rotating shaft 6, a fixing bolt 10 inside the fixing base plate 7, and a support component on the outer wall of the inclined support column 5 for supporting the reinforced concrete column 1.

[0026] The support assembly includes a connecting column 8 and a support column 9. One end of the connecting column 8 is rotatably connected to the upper side of the outer wall of the inclined support column 5, and the other end of the connecting column 8 is fixedly connected to the outer wall of the reinforced concrete column 1. One end of the support column 9 is rotatably connected to the lower side of the outer wall of the inclined support column 5, and the other end of the support column 9 is fixedly connected to the bottom of the reinforced concrete column 1. The fixing assembly includes a base 2. The outer wall of the base 2 is fixedly connected to the bottom of the reinforced concrete column 1, and multiple fixing bolts 3 are provided at the bottom of the reinforced concrete column 1.

[0027] Specifically, firstly, the reinforced concrete column 1 is firmly fixed in the pre-prepared designated position using fixing bolt 3, thus ensuring the initial positioning and stability of the column. Then, the base 2 provides foundational support for the reinforced concrete column 1, further enhancing its initial stability. Next, the operator pulls the inclined support column 5, allowing one end of the inclined support column 5 to rotate freely on the outer wall of the rotating shaft 4. This causes the other end of the inclined support column 5 to gradually descend under the influence of the rotating shaft 6, bringing it into contact with the ground together with the fixed base plate 7, achieving close contact with the foundation. At this point, the fixed base plate 7 is firmly fixed using fixing bolt 10, further stabilizing the inclined support column. The connection between the support column 5 and the foundation: After the inclined support column 5 is fixed, its pulling force will drive the connecting column 8 and the support column 9 to move synchronously through the mechanical connection. During this process, one end of the connecting column 8 will be close to the middle of the reinforced concrete column 1, while one end of the support column 9 will be firmly against the bottom of the reinforced concrete column 1. This forms two intersecting triangular support structures between the reinforced concrete column 1, the connecting column 8, the support column 9, and the inclined support column 5. This geometrically stable structure effectively disperses the effects of various forces from the outside, such as wind load and line tension, ensuring that the reinforced concrete column 1 can achieve further efficient support and fixation in various complex environments.

[0028] Reference Figure 3 and Figure 4 A positioning seat 12 is slidably connected to the top of the reinforced concrete column 1. A reinforced concrete composite column 11 is fixedly connected to the upper surface of the positioning seat 12. A utility pole 16 is fixedly connected to the upper surface of the reinforced concrete composite column 11. A reinforcing rib 13 is fixedly connected inside the reinforced concrete column 1. A connecting component is provided inside the positioning seat 12. The connecting component is used to connect and fix the reinforced concrete column 1 and the positioning seat 12. The connecting component includes a screw 14. The outer wall of the screw 14 is slidably connected to the interior of the reinforced concrete column 1 and the positioning seat 12. Nuts 15 are threaded to both ends of the screw 14. 5 are arranged in a ring array around the reinforced concrete column 1. The diagonal support column 5 is used to support and reinforce the reinforced concrete column 1. The connecting column 8 is set above the support column 9. The connecting column 8, support column 9, diagonal support column 5 and reinforced concrete column 1 form two triangular support structures. The reinforcing rib 13 is slidably connected inside the positioning seat 12. The reinforcing rib 13 is used to reinforce the reinforced concrete column 1 and the reinforced concrete composite column 11. The outer wall of the nut 15 is attached to the outer wall of the positioning seat 12. The nut 15 is used to fix the screw 14 inside the reinforced concrete column 1 and the positioning seat 12.

[0029] Specifically, the positioning seat 12 at the bottom of the reinforced concrete composite column 11 is inserted into the top of the reinforced concrete column 1. This process, through the sliding connection function of the positioning seat 12, precisely positions the reinforced concrete composite column 11, ensuring a stable connection between it and the column. During this process, the reinforcing rib 13 inside the top of the reinforced concrete column 1 moves accordingly and embeds into the internal space of the reinforced concrete composite column 11 and the positioning seat 12, effectively reinforcing the entire connection node. Subsequently, the screw 14 is passed through the internal channel between the positioning seat 12 and the reinforced concrete column 1. Utilizing the insertion of the screw 14 and the tightening action of the nuts 15 at both ends, the connection point between the reinforced concrete column 1 and the reinforced concrete composite column 11 is firmly fixed. This tight connection method not only improves the overall rigidity of the structure but also significantly enhances the wind and vibration resistance of the pole 16 through the supporting effect of the reinforcing rib 13, thereby ensuring the long-term reliability and safety of the assembled structure. Through this process, the pole 16 structure achieves efficient support and stable installation from bottom to top, meeting the usage requirements under complex conditions in a wind farm environment.

[0030] Working principle: When using prestressed reinforced concrete poles for wind farms, the reinforced concrete column 1 is first fixed in the designated position using fixing bolt 3. Then, the base 2 provides initial support for the reinforced concrete column 1. Next, the inclined support column 5 is pulled, causing one end of the inclined support column 5 to rotate on the outer wall of the rotating shaft 4. This causes the other end of the inclined support column 5 to work with the rotating shaft 6 to bring the fixed base plate 7 into contact with the ground. Then, the fixed base plate 7 is fixed using fixing bolt 10. After the inclined support column 5 is fixed, the movement of the inclined support column 5 will cause the connecting column 8 and the support column 9 to move. One end of the connecting column 8 will abut against the middle of the reinforced concrete column 1, while one end of the support column 9 will abut against the bottom of the reinforced concrete column 1. At this time, two triangular support structures will be formed between the reinforced concrete column 1, the connecting column 8, the support column 9 and the inclined support column 5, thereby achieving further support and fixation of the reinforced concrete column 1 and achieving efficient support and fixation of the reinforced concrete column 1.

[0031] In addition, during use, the positioning seat 12 at the bottom of the reinforced concrete composite column 11 is inserted into the top of the reinforced concrete column 1. This process positions the reinforced concrete composite column 11 through the positioning seat 12, thereby moving the reinforcing rib 13 at the top of the reinforced concrete column 1 into the interior of the reinforced concrete composite column 11 and the positioning seat 12 for reinforcement. Finally, the screw 14 is passed through the positioning seat 12 and the interior of the reinforced concrete column 1 to achieve the connection and fixation between the reinforced concrete column 1 and the reinforced concrete composite column 11, thus facilitating assembly.

[0032] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
