Description

Technical Field

[0001] This utility model relates to the field of new energy engineering technology, and in particular to a cooling water pipe arrangement structure suitable for wind turbine foundations. Background Technology

[0002] In the construction of onshore wind power projects, wind turbine foundations are typically large-volume concrete structures. During the hardening process, the concrete undergoes a hydration reaction, releasing a significant amount of heat, known as heat of hydration. Excessive heat of hydration can lead to a large temperature difference between the inside and outside of the concrete, generating substantial thermal stress. When this stress exceeds the tensile strength of the concrete, it can trigger thermal cracks. Furthermore, when the internal temperature of the concrete is too high, the calcium sulfoaluminate (ettringite) produced during the hardening process dehydrates and decomposes. When the dehydrated components encounter water again, they undergo a hydration reaction, producing expansive ettringite, which damages the existing concrete structure, causing cracks. This affects the structural integrity and long-term safety of the wind turbine foundation, posing a serious safety hazard.

[0003] To effectively control the heat of hydration in large-volume concrete and prevent cracking, temperature control measures such as pre-embedding cooling water pipes inside the concrete foundation are commonly used in engineering practice. By circulating cooling water through the pipes, the heat of hydration inside the concrete is promptly removed, keeping the maximum temperature of the concrete and the temperature difference between the inside and outside within the design limits.

[0004] In existing technologies, the commonly used cooling water pipe arrangement in wind turbine foundations is the U-shaped water pipe arrangement. This arrangement typically involves multiple layers of water pipes arranged along the height of the foundation, with each layer consisting of one or more pipes bent into a U-shape, covering the main area of ​​the foundation. However, this traditional U-shaped water pipe arrangement has several technical drawbacks when applied to modern wind turbine foundations, especially circular foundations: 1. The reinforcing steel bars in circular wind turbine foundations are usually arranged radially and circumferentially. The straight sections of the U-shaped water pipes do not align with the direction of the reinforcing steel bars, making them difficult to securely tie and fix. This often requires additional specialized fasteners, increasing the amount of reinforcing steel work, construction costs, and construction complexity; 2. The central area of ​​the wind turbine foundation usually has a ring-shaped distribution of anchor bolt assemblies (i.e., pre-embedded anchor bolt rings). The reinforcing steel bars in and around this area are dense. To cover the entire foundation cross-section, the U-shaped water pipes must pass through the densely reinforced area where the anchor bolt rings are located multiple times. This makes the installation and insertion of the water pipes extremely difficult, greatly complicating construction, and in some cases, it may be impossible to reserve sufficient installation space for the water pipes. Utility Model Content

[0005] The purpose of this utility model is to provide a cooling water pipe layout structure suitable for wind turbine foundations, which can be well matched with the steel reinforcement layout of wind turbine foundations, simplify the fixing method, and effectively avoid areas with dense steel reinforcement, i.e., pre-embedded anchor bolt rings, thereby reducing the difficulty of cooling water pipe layout and improving construction efficiency and reliability.

[0006] To achieve the above objectives, this utility model provides a cooling water pipe arrangement structure suitable for wind turbine foundations. The wind turbine foundation includes a foundation body and pre-embedded anchor bolt rings embedded in the foundation body, comprising:

[0007] A ring pipe assembly is disposed within the foundation body and located outside the pre-embedded anchor bolt ring. The ring pipe assembly includes multiple ring pipe layers spaced apart along the height direction of the wind turbine foundation. The inlet and outlet of each ring pipe layer are located on the outer surface of the foundation body.

[0008] A spiral tube assembly is disposed within the foundation body and located inside the pre-embedded anchor ring. The inlet and outlet of the spiral tube assembly are both located on the outer surface of the foundation body.

[0009] Furthermore, the foundation body is divided into a first region, a second region, and a third region from the inside out from the pre-embedded anchor bolt ring. The ring pipe layer that spans the first region, the second region, and the third region is called the first ring pipe layer. The ring pipe layer that spans the first region and the second region is called the second ring pipe layer. The ring pipe layer that is set in the first region is called the third ring pipe layer.

[0010] The first ring layer includes a first ring loop, a second ring loop, and a third ring loop arranged coaxially from the inside to the outside;

[0011] The second ring layer includes a fourth ring loop and a fifth ring loop arranged coaxially from the inside to the outside;

[0012] The third ring pipe layer includes a sixth ring pipe loop;

[0013] The first ring circuit, the fourth ring circuit, and the sixth ring circuit have the same structure, and the second ring circuit and the fifth ring circuit have the same structure.

[0014] The inlets and outlets of the first, second, third, fourth, fifth, and sixth ring pipe circuits are all located on the outer surface of the main body of the foundation.

[0015] Furthermore, the first ring pipe circuit includes at least one first cooling pipe unit, the inlet and outlet of which are both located on the outer surface of the base body.

[0016] Wherein, when the number of the first cooling pipe units is greater than or equal to two, the first cooling pipe units are arranged concentrically and coaxially at intervals.

[0017] Furthermore, the first cooling pipe unit includes three first cooling ring pipes arranged concentrically and coaxially at intervals, and the three first cooling ring pipes are connected to each other.

[0018] Furthermore, the second ring circuit includes at least one second cooling pipe unit, the inlet and outlet of which are both located on the outer surface of the base body.

[0019] When the number of the second cooling pipe units is greater than or equal to two, the second cooling pipe units are arranged concentrically and coaxially at intervals.

[0020] Furthermore, the second cooling pipe unit includes two second cooling ring pipes arranged concentrically and coaxially at intervals, and the two second cooling ring pipes are connected to each other.

[0021] Furthermore, the third ring circuit includes at least one third cooling ring pipe, the inlet and outlet of which are both located on the outer surface of the base body;

[0022] When the number of the third cooling ring pipes is greater than or equal to two, the third cooling ring pipes are arranged concentrically and coaxially at intervals.

[0023] Furthermore, the spiral tube assembly includes a plurality of spiral cooling tubes that are concentrically and coaxially spaced from the inside to the outside of the base body, and the inlet and outlet of the spiral cooling tubes are both located on the outer surface of the base body.

[0024] Compared with the prior art, the cooling water pipe arrangement structure of this utility model embodiment suitable for wind turbine foundations has the following advantages:

[0025] 1. Simplified fixing and cost saving: The ring pipe assembly adopts a ring arrangement parallel to the circumferential steel bars of the wind turbine foundation, which can be easily tied and fixed directly to the steel bars of the wind turbine foundation itself. This avoids the need to add special fasteners due to inconsistent routing, simplifies the fixing process of water pipes, and reduces construction costs.

[0026] 2. Reduce construction difficulty and improve feasibility: By dividing the cooling water pipe into a ring pipe assembly located outside the pre-embedded anchor bolt ring and a spiral pipe assembly located inside, the cooling water pipe is prevented from having to pass through the densely reinforced area of ​​the pre-embedded anchor bolt ring, which reduces the on-site installation difficulty and improves the construction feasibility and efficiency of the water pipe layout scheme.

[0027] 3. Segmented cooling for better temperature control: The fan foundation is divided into inner and outer zones for independent cooling. The spiral tube assembly on the inner side can efficiently cool the core area of ​​the foundation where the heat of hydration is most concentrated. The ring tube assembly on the outer side is responsible for cooling the larger peripheral area. This makes the distribution of cooling water flow more reasonable and the heat removal more efficient. This enables precise control of the temperature of the fan foundation section, effectively preventing the formation of temperature cracks and further ensuring the structural safety and long-term reliability of the fan foundation.

[0047] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0048] In this description of the utility model, the terms "upper," "lower," "left," "right," "front," "rear," "inner," "outer," "lateral," and "longitudinal," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are used solely for the convenience of describing the utility model and for simplifying the description, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model. Those skilled in the art can understand the specific meaning of these terms in this utility model according to the specific circumstances.

[0049] In this description of the utility model, the terms "provided with," "set up," "connected," and "placed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0050] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0051] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0052] like Figure 1-6As shown in the figure, a cooling water pipe arrangement structure suitable for a fan foundation 1 according to an embodiment of the present invention is provided. The fan foundation 1 includes a foundation body 11 and pre-embedded anchor bolt rings 12 embedded in the foundation body 11, including:

[0053] The ring pipe assembly 2 is set inside the foundation body 11 and is located outside the pre-embedded anchor bolt ring 12. The ring pipe assembly 2 includes multiple ring pipe layers 21 spaced apart along the height direction of the wind turbine foundation 1. The inlet and outlet of each ring pipe layer 21 are located on the outer surface of the wind turbine foundation 1.

[0054] The spiral tube assembly 3 is installed inside the foundation body 11 and located inside the pre-embedded anchor ring 12. The inlet and outlet of the spiral tube assembly 3 are both located on the outer surface of the fan foundation 1.

[0055] Based on the above technical solutions

[0056] The cooling water pipe system is divided into a ring pipe assembly 2 located outside the pre-embedded anchor bolt ring 12 and a spiral pipe assembly 3 located inside, forming a zoned layout structure. This reduces construction difficulty and improves construction feasibility. The area with the densest reinforcement and the most difficult construction in the wind turbine foundation 1 is the pre-embedded anchor bolt ring 12 and its vicinity. The existing U-shaped cooling water pipe scheme must force its way through this area, leading to installation difficulties. The U-shaped cooling water pipe has higher requirements for the layout between the U-shaped cooling water pipe and the reinforcement. By arranging bolt pipe assemblies and ring pipe assemblies 2 on the inner and outer sides of the anchor bolt ring respectively, this problem is directly avoided, reducing the technical requirements for installation and improving construction efficiency. Zoned temperature control is achieved, improving cooling efficiency and the construction quality of the wind turbine foundation 1. The heat of hydration of concrete is unevenly distributed inside the wind turbine foundation 1, with the central part usually having the highest temperature. The spiral pipe assembly 3 can concentrate the heat in the central part for efficient cooling. The ring pipe assembly 2 is responsible for fully covering the larger but relatively lower temperature-rising outer part, effectively controlling the temperature of the entire wind turbine foundation 1, thereby more effectively preventing the generation of temperature cracks and ensuring the final project quality.

[0057] Each ring pipe layer 21 of the ring pipe assembly 2 has an inlet and an outlet leading to the outer surface of the foundation body 11. Similarly, the spiral pipe assembly 3 also has an inlet and an outlet leading to the outer surface of the foundation body 11. Since concrete of different heights reaches its peak hydration heat at different times, the ring pipe layers 21 of different heights can be independently cooled according to the concrete pouring and solidification process. This ensures a high degree of spatial matching between cooling resource input and actual heat dissipation demand, improving cooling efficiency and guaranteeing energy savings. If a ring pipe layer 21 becomes blocked, leaks, or is damaged, the fault will be isolated within that ring pipe layer 21 without affecting the normal operation of other ring pipe layers 21, which can still provide cooling for the foundation. This "fault-tolerant design" improves the reliability of the entire temperature control process and avoids the risk of the entire cooling structure failing due to a single point of failure.

[0058] Preferably, the foundation body 11 is divided into a first region 111, a second region 112 and a third region 113 from the inside out from the pre-embedded anchor ring 12. The ring pipe layer 21 that spans the first region 111, the second region 112 and the third region 113 is called the first ring pipe layer 211, the ring pipe layer 21 that spans the first region 111 and the second region 112 is called the second ring pipe layer 212, and the ring pipe layer 21 set in the first region 111 is called the third ring pipe layer 213.

[0059] The first ring tube layer 211 includes a first ring tube loop 2111, a second ring tube loop 2112 and a third ring tube loop 2113 arranged coaxially from the inside to the outside;

[0060] The second ring pipe layer 212 includes a fourth ring pipe loop 2121 and a fifth ring pipe loop 2122;

[0061] The third ring pipe layer 213 includes the sixth ring pipe loop 2131;

[0062] The first ring circuit 2111, the fourth ring circuit 2121, and the sixth ring circuit 2131 have the same structure, and the second ring circuit 2112 and the fifth ring circuit 2122 have the same structure.

[0063] The inlets and outlets of the first ring pipe circuit 2111, the second ring pipe circuit 2112, the third ring pipe circuit 2113, the fourth ring pipe circuit 2121, the fifth ring pipe circuit 2122, and the sixth pipe circuit are all located on the outer surface of the main body 11.

[0064] The fan foundation 1 is layered along its height (first ring pipe layer 211, second ring pipe layer 212, third ring pipe layer 213), and the ring pipe layer 21 is divided into sections along its radial direction (first ring pipe loop 2111, second ring pipe loop 2112, third ring pipe loop 2113). Each independent ring pipe loop is equipped with inlet and outlet water outlets leading to the outer surface of the foundation body 11, forming a three-dimensional cooling structure. Each layer (first ring pipe layer 2111, second ring pipe loop 2112, third ring pipe loop 2113) can be independently adjusted according to the hydration heat process of the concrete at different heights. 1. Cooling water flow rate of the second ring pipe layer 212 and the third ring pipe layer 213; radial independent control, even within the same ring pipe layer 21, the temperature of different radial regions (first region 111, second region 112, and third region 113) can be independently controlled. The water inflow of each region can be adjusted at any time according to the different stages of pouring and the changes in concrete temperature. While performing precise cooling at fixed points, the amount of cooling water used is controlled. Cooling water resources are used rationally, and excellent temperature control effect is achieved with less energy consumption, ensuring the engineering quality of the fan foundation 1.

[0065] More preferably, the first ring pipe circuit 2111 includes at least one first cooling pipe unit 21111, and the inlet and outlet of the first cooling pipe unit 21111 are both located on the outer surface of the base body 11.

[0066] When the number of first cooling pipe units 21111 is greater than or equal to two, the first cooling pipe units 21111 are arranged concentrically and coaxially at intervals.

[0067] More preferably, the first cooling pipe unit 21111 includes three first cooling ring pipes 211111 arranged concentrically and coaxially, and the three first cooling ring pipes 211111 are connected to each other.

[0068] More preferably, the second ring pipe circuit 2112 includes at least one second cooling pipe unit 21121, and the inlet and outlet of the second cooling pipe unit 21121 are both located on the outer surface of the base body 11.

[0069] When the number of second cooling pipe units 21121 is greater than or equal to two, the second cooling pipe units 21121 are arranged concentrically and coaxially at intervals.

[0070] More preferably, the second cooling pipe unit 21121 includes two second cooling ring pipes 211211 arranged concentrically and coaxially, and the two second cooling ring pipes 211211 are connected to each other.

[0071] More preferably, the third ring pipe circuit 2113 includes at least one third cooling ring pipe 21131, and the inlet and outlet of the third cooling ring pipe 21131 are both located on the outer surface of the base body 11.

[0072] When the number of third cooling ring pipes 21131 is greater than or equal to two, the third cooling ring pipes 21131 are arranged concentrically and coaxially at intervals.

[0073] First loop 2111: This loop corresponds to the first area 111, which is composed of at least one first cooling pipe unit 21111. When the area to be covered is wide, two or more first cooling loops 211111 can be set to form a parallel water circuit.

[0074] Second ring pipe circuit 2112: This circuit corresponds to the second area 112, which is composed of at least one second cooling pipe unit 21121. When the area to be covered is wide, two or more first cooling pipe units 21111 can be set to form a parallel water circuit.

[0075] Third ring pipe circuit 2113: This circuit corresponds to the third region 113, which is composed of at least one third cooling ring pipe 21131. When the area to be covered is wide, two or more third cooling ring pipes 21131 can be set to form a parallel water circuit.

[0076] This ensures that the cooling water flow distribution among the first cooling pipe unit 21111, the second cooling pipe unit 21121, and the third cooling ring pipe 21131 in the same ring pipe layer 21 is relatively uniform. By connecting them in series, the effective cooling path of the first cooling pipe unit 21111 and the second cooling pipe unit 21121 is increased, the heat exchange utilization rate of the cooling water is improved, and the waste of cooling water resources is avoided.

[0077] Specifically, the spacing between the first cooling ring pipes 211111, the spacing between the first cooling ring pipe 211111 and the first cooling pipe unit 21111, the spacing between the second cooling ring pipes 211211, the spacing between the first cooling pipe unit 21111 and the second cooling pipe unit 21121, and the spacing between the third cooling ring pipes 21131 are the same.

[0078] This design creates a regular and unobstructed vertical vibration channel, effectively avoiding construction interference. By setting a uniform and standardized horizontal spacing between all pipes on the same floor, uniform vertical gaps are created within the coverage area of ​​the entire ring pipe assembly 2. During concrete pouring, the vibrator used by construction workers needs to be vertically inserted through the gaps between the upper steel mesh and pipes to vibrate the lower layer of concrete. The equidistant spacing design of this scheme provides a smooth and unobstructed channel for the lowering, operation, and lifting of the vibrator. It effectively avoids problems such as the vibrator getting stuck, unable to reach the specified depth, or unable to be smoothly pulled out due to the distribution of cooling pipes, eliminating construction interference, ensuring the continuity and efficiency of vibration operations, and thus ensuring the structural safety and long-term stability of the wind turbine foundation 1.

[0079] Preferably, the spiral tube assembly 3 includes a plurality of spiral cooling tubes 31 that are concentrically and coaxially distributed from the inside to the outside of the base body 11, and the inlet and outlet of the spiral cooling tubes 31 are both located on the outer surface of the base body 11.

[0080] This system achieves three-dimensional, seamless cooling coverage of the central area of ​​the foundation 11. The spiral cooling pipe 31, with its spiral tube structure, allows for simultaneous radial (horizontal) and axial (vertical) cooling of the concrete. Compared to the layered horizontal ring pipes on the outer side, a single spiral cooling pipe 31 constitutes a three-dimensional cooling structure. By using multiple concentric and coaxial spiral pipes, it further ensures that the entire cylindrical or frustum-shaped area from the center point to the inner wall of the anchor ring is uniformly and seamlessly covered by the spiral cooling pipe 31, effectively removing the heat of hydration from the concrete.

[0081] This design simplifies construction in the central area, where the reinforcement bars are extremely dense, making the layered installation and connection of horizontal pipes very difficult. The spiral cooling pipe 31 in this solution can be pre-formed off-site or on the ground, creating an independent, prefabricated structure. During construction, this prefabricated spiral cooling pipe 31 is simply hoisted into the reinforcement cage inside the anchor ring and then positioned and fixed. This simplifies construction procedures in confined, dense spaces, significantly shortens construction time, and substantially reduces the risk of construction errors due to on-site difficulties.

[0082] It is easy to achieve hydraulic balance. The complex central area cooling task is decomposed into multiple spiral cooling pipes 31 with similar structure and similar hydraulic resistance, which are connected in parallel. This makes it easier and more uniform to distribute cooling water to each spiral cooling pipe 31, ensuring the uniformity of cooling of the entire central area and avoiding complex flow balance design.

[0083] In summary, this utility model embodiment provides a cooling water pipe arrangement structure suitable for a wind turbine foundation 1, which simplifies fixing and saves costs: the ring pipe assembly 2 adopts a ring arrangement parallel to the circumferential reinforcement of the wind turbine foundation 1, which can be easily and directly tied and fixed to the reinforcement of the wind turbine foundation 1 itself, avoiding the need for additional special fasteners due to inconsistent routing, simplifying the water pipe fixing process and reducing construction costs; reducing construction difficulty and improving feasibility: by dividing the cooling water pipe into the ring pipe assembly 2 located outside the pre-embedded anchor bolt ring 12 and the spiral pipe assembly 3 located inside, the cooling water pipe is prevented from having to pass through the densely reinforced area of ​​the pre-embedded anchor bolt ring 12, reducing the on-site installation difficulty and improving the construction feasibility and efficiency of the water pipe arrangement scheme. The system achieves segmented cooling with excellent temperature control: the fan foundation 1 is divided into inner and outer zones for independent cooling. The spiral tube assembly 3 on the inner side can efficiently cool the core area of ​​the foundation where the heat of hydration is most concentrated. The ring tube assembly 2 on the outer side is responsible for the overall cooling of the larger peripheral area. This makes the distribution of cooling water flow more reasonable and the heat removal more efficient. Moreover, the water intake of each zone can be adjusted at any time according to the different stages of pouring and changes in concrete temperature. While performing precise cooling at fixed points, the amount of cooling water used is controlled. The rational use of cooling water resources enables precise control of the cross-sectional temperature of the fan foundation 1, effectively preventing the generation of temperature cracks and further ensuring the structural safety and long-term reliability of the fan foundation 1.

[0084] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
