Description

Technical Field

[0001] This application relates to the field of steam turbine generator base technology, and in particular to a steel-concrete composite steam turbine generator base. Background Technology

[0002] Steam turbines and generators are the core equipment of power plants. The steam turbine generator base, as an important structure supporting the steam turbine and generator, is crucial for ensuring the stable operation of the equipment.

[0003] Currently, reinforced concrete support columns are commonly used for turbine generator bases, with the platform connected to the foundation via these columns. However, reinforced concrete support columns have the following disadvantages: 1) Large self-weight: In traditional reinforced concrete support column design, to improve the rigidity of the support column, the cross-section is often designed to be very large, reaching over 2m, resulting in material waste. Furthermore, the excessively large cross-section increases the self-weight, requiring stronger foundation design and increasing the overall cost of the turbine generator base; 2) Complex construction process: Traditional reinforced concrete support columns require tying reinforcing bars and erecting formwork during fabrication. After the concrete has cured, the formwork needs to be removed, resulting in numerous procedures. In addition, a certain number of steel embedded parts need to be pre-embedded in the column body as suspension points for pipeline facilities, further increasing the number of procedures; 3) High construction difficulty: Traditional reinforced concrete support columns have a large cross-section, dense reinforcement arrangement, and a large volume of concrete poured. This places higher demands on the accuracy of reinforcing bar tying and the compaction of concrete vibration. Furthermore, the concrete will produce… The water turns into heat, and if the temperature of the large-volume concrete support column is not properly controlled, it is easy to crack, which will affect the normal use of the structure; 4) The space utilization efficiency is low. The cross section of the traditional reinforced concrete support column is large, which will occupy more space and restrict the layout and installation of equipment and pipelines around the base, resulting in low space utilization efficiency; 5) The traditional steam turbine generator base usually has angle steel pre-embedded at the four corners of the support column as the support points of the pipeline; however, the angle steel is not involved in the stress calculation of the support column during the design and is only used as the support point of the pipeline, which will cause a waste of the support column reinforcement; in addition, the angle steel and the reinforced concrete column need to be connected by anchor bars, which will also cause a waste of anchor bars; (6) When the steam turbine and generator are running, the vibration of the intermediate platform of the traditional steam turbine generator base is often large. The busbar of the intermediate platform is more sensitive to vibration. Excessive vibration can easily cause damage to the busbar, which in turn causes the failure of the power generation system.

[0004] Therefore, there is an urgent need in this field to develop a steel-concrete composite turbine generator base. This base uses steel-concrete composite support columns and improves the support structure and its connection nodes. It can not only reduce the cross-sectional dimensions and simplify the construction process, but also improve the cross-sectional bearing capacity and stiffness, which has significant advantages.

[0050] Through extensive and in-depth research, the inventors have developed for the first time a steel-concrete composite turbine generator base. The supporting columns in this base are made of steel-concrete composite, which significantly reduces the column cross-sectional dimensions and improves its load-bearing capacity and stiffness while ensuring stable equipment operation and structural safety. This application also modifies the position of the vibration isolators by installing rubber vibration isolators between the top platform and the turbine generator base to reduce vibration.

[0051] In the following description, many technical details are presented to help the reader better understand this application. However, those skilled in the art will understand that the technical solutions claimed in this application can be implemented even without these technical details and various variations and modifications based on the following embodiments.

[0052] the term

[0053] Steam turbine generator base: The frame structure that supports the steam turbine and generator.

[0054] In this invention, all directional indicators (such as up, down, left, right, front, back, etc.) are only used to explain the relative positional relationships and movement of the components in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indicators will also change accordingly. This application has at least one of the following advantages:

[0055] (a) The steel-concrete composite turbine generator base of this application has high strength, good stability and strong bearing capacity. Through the restraint effect of the steel pipe on the core concrete, the concrete is in a triaxial compression state, which significantly improves the compressive strength of the concrete. At the same time, the presence of concrete can prevent the buckling of the steel pipe and improve its stability.

[0056] Optionally, (b) the steel-concrete composite turbine generator base of this application has high rigidity and small deformation. The steel pipe and concrete work together, resulting in high overall rigidity. Under load, the structure deforms little and can effectively resist the unbalanced torque generated by the turbine generator starting and stopping, ensuring stable operation of the equipment.

[0057] Optionally, (c) the steel-concrete composite steam turbine generator base of this application is easy to construct and has a short construction period. The steel-concrete composite column does not require formwork, steel reinforcement binding and other procedures. Moreover, the steel pipe can be directly used as the pipe support point, without the need for pre-embedded steel plates, which simplifies the construction process and shortens the on-site construction time.

[0058] Optionally, (d) the steel-concrete composite turbine generator base of this application makes full use of material properties, with a compact cross-section and saves space. The steel-concrete composite column can fully utilize the tensile properties of steel and the compressive properties of concrete, and the material properties are fully utilized. When achieving the same bearing capacity requirements, it is often smaller than the cross-section of traditional reinforced concrete columns, which can reserve more space for equipment layout, pipeline installation, etc., and is suitable for the compact layout requirements of large power plants.

[0059] Optionally, (e) the steel-concrete composite turbine generator base of this application can save steel, and the steel pipe of the steel-concrete composite support column can also serve as the support point for the pipeline, which can save a lot of angle steel and anchor bars compared with traditional support columns.

[0060] Optionally, (f) the steel-concrete composite turbine generator base of this application can significantly reduce the impact of vibration on facilities such as busbars on the intermediate platform by arranging the intermediate platform independently;

[0061] Optionally, (g) the steel-concrete composite turbine generator base of this application has outstanding dynamic performance. By using rubber vibration isolators, the vibration generated during equipment operation can be effectively blocked, thereby improving the service life of the base and the equipment. By optimizing the arrangement of the vibration isolators, the vibration of the equipment is isolated at the top of the base plate. Compared with the traditional vibration isolator arrangement method (that is, the vibration isolators are arranged at the top of the support column), the thickness of the base plate can be significantly reduced, and the amount of reinforced concrete used can be reduced.

[0062] Optionally, (h) the rubber vibration isolator has a large internal damping and can effectively block vibration when the disturbance frequency passes through the resonance zone during the equipment start-up and shutdown phases without the need for a damper.

[0063] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. It should be understood that these are merely examples provided to the reader of possible implementations of this utility model, and are not intended to limit the scope of this utility model.

[0064] See Figures 1-8This application provides a steel-concrete composite steam turbine generator base, including a bottom foundation platform 4, a top platform 1, a supporting structure, and an intermediate platform structure. The steam turbine generator set is installed on the top platform 1, and its thickness can be designed to be 1.5m-2.0m depending on the load. The holes 7 on the top platform 1 are for equipment and pipeline installation. The supporting structure includes multiple steel-concrete composite support columns 3, vertically arranged between the bottom foundation platform 4 and the top platform 1. The vertical distance between the bottom foundation platform 4 and the top platform 1 is 8.0m-12.0m.

[0065] See Figure 4 The steel-concrete composite support column 3 mainly consists of two parts: an outer steel pipe 9 and concrete 8 filled inside the steel pipe 9. By selecting different types of steel pipes and concrete, it can be equipped with load-bearing capacity. By adjusting the wall thickness and size of the steel pipe, the rigidity and dynamic performance of the support column can be changed to meet the normal operation requirements of the equipment. The steel-concrete composite support column 3 is reliably connected with the top platform 1 and the bottom foundation platform 4 to form a whole and work together.

[0066] Preferably, the outer steel pipe 9 can be a seamless steel pipe or a welded steel pipe. Preferably, the outer steel pipe 9 has a circular, square, or rectangular cross-sectional shape. The concrete filled in the steel pipe is generally ordinary concrete or high-strength concrete. A small number of reinforcing bars can be locally installed inside the steel pipe according to actual needs to improve the performance of the supporting column.

[0067] The steel pipes of the concrete-filled steel pipe support column can also serve as support points for pipelines and other facilities, saving a significant amount of angle steel and anchor bars compared to traditional support columns.

[0068] See Figure 5 and Figure 6 The diagram shows the connection node between the steel-concrete composite support column 3 and the top platform 1. By reserving radial reinforcing bars at the top of the steel-concrete composite support column 3, it is reliably connected to the top platform 1. Specifically, the steel-concrete composite support column 3 is directly connected to the top platform 1 through a first connection structure: the first connection structure includes multiple vertical connecting reinforcing bars 10, which are embedded in the top concrete of the support column 3 and extend upward to anchor to the top platform 1.

[0069] Preferably, the vertical connecting steel bars 10 are welded to the inner wall of the outer steel pipe of the steel-concrete composite support column 3 and are evenly arranged around its perimeter. The length of the vertical connecting steel bars 10 in the concrete 8 is 1.0m-1.5m, that is, the anchorage length in the concrete is 1.0m-1.5m. Preferably, there are 8 vertical connecting steel bars 10, which are arranged at equal intervals.

[0070] Preferably, the first connecting structure further includes a transversely arranged circumferential connecting steel bar, which surrounds the vertical connecting steel bar 10 for fastening the vertical connecting steel bar 10. More preferably, the steel bars are evenly spaced in the vertical direction, and the number of steel bars is 4.

[0071] See Figure 7 and Figure 8 The diagram illustrates the connection node between the bottom of the concrete-filled steel tube support column 3 and the bottom foundation platform 4. A perforated base plate 12 is welded to the bottom of the concrete-filled steel tube support column to better transmit vertical forces, and studs are welded to the portion of the concrete-filled steel tube support column 3 inserted into the foundation to enhance shear resistance. Specifically, the bottom of the concrete-filled steel tube support column 3 is fixed to the bottom foundation platform 4 via a second connection structure, with the bottom of the concrete-filled steel tube support column 3 inserted into the bottom foundation platform 4. The second connection structure includes a perforated base plate 12 welded to the bottom end of the concrete-filled steel tube support column 3 and multiple studs 11. The perforated base plate 12 is used to transmit vertical loads; the studs 11 are welded at intervals along the circumferential outer wall of the bottom of the concrete-filled steel tube support column 3 to enhance shear resistance. Preferably, multiple studs 11 are also spaced at intervals in the vertical direction.

[0072] See Figures 1-3 The intermediate platform structure is independently arranged, meaning that intermediate platform columns (such as the first intermediate platform column 51 and the second intermediate platform column 52) are separately installed from the bottom foundation platform 4 to support the platform plate 2. By setting up an independent intermediate platform structure, it is protected from equipment vibration, ensuring the normal operation of auxiliary equipment, busbars, and other facilities on the intermediate platform structure. The intermediate platform is used to house auxiliary equipment of the steam turbine generator set, support pipes (such as steam pipes, oil pipes, water pipes, etc.), and cable trays, and can also serve as a maintenance platform.

[0073] The intermediate platform structure is completely independent of the supporting structure. The intermediate platform structure is set between two adjacent steel pipe concrete support columns 3 and is a certain distance away from the two adjacent steel pipe concrete support columns 3 to avoid vibration transmission. The intermediate platform structure includes an intermediate platform plate 2, a first intermediate platform column 51 and a second intermediate platform column 52 for supporting the intermediate platform plate 2. The intermediate platform plate 2 is set on the first intermediate platform column 51 and the second intermediate platform column 52.

[0074] Preferably, two adjacent steel-concrete composite support columns 3 include a first steel-concrete composite support column 31 and a second steel-concrete composite support column 32. The horizontal distance between the first steel-concrete composite support column 31 and the first intermediate platform column 51 is 0.15m-0.3m, and the horizontal distance between the second steel-concrete composite support column 32 and the second intermediate platform column 52 is 0.15m-0.3m.

[0075] Preferably, the first intermediate platform column 51 and the second intermediate platform column 52 are directly supported on the bottom foundation platform 4, that is, the first intermediate platform column 51 and the second intermediate platform column 52 are directly anchored to the bottom foundation platform 4. Preferably, the cross-sectional dimension of the intermediate platform column 51 is 0.4m-0.6m.

[0076] Furthermore, in order to resist equipment vibration, traditional intermediate platforms often have very large intermediate platform plates with a thickness of 0.6m-1.2m. However, this utility model arranges the intermediate platform independently, eliminating the interference of equipment vibration. The thickness of the platform plate 2 is optimized to 0.1m-0.15m. Although there are more intermediate platform columns, it can still save a lot of steel bars and concrete compared with the traditional solution, and extend the service life of related equipment on the intermediate platform.

[0077] This embodiment incorporates vibration isolation design to further optimize vibration control. The position of the vibration isolator is changed, and a rubber vibration isolator (not shown) is installed between the top platform 1 and the turbine generator base. Preferably, the rubber vibration isolator is a compression type, a shear type, or a compression-shear type. By changing the position of the rubber vibration isolator, it is installed on the top surface of the top platform 1, isolating vibration, thus significantly reducing the thickness of the top platform. For example, the thickness of the platform of a traditional non-vibration-isolated base or a spring-isolated base is generally 2.5m-3.0m, while the platform of this application is 1.5m-2.0m, thereby reducing the amount of reinforced concrete used.

[0078] By changing the position of the vibration isolator and replacing the support column 3 with a steel-concrete composite support column 3, the cross-sectional area of ​​the steel-concrete composite support column is between 1.0m and 1.5m. Because the cross-sectional dimensions of the base column (support column) are controlled by strength indicators during the design process after the vibration isolator is installed, since very little vibration is transmitted to the support column 3, the cross-sectional dimensions of the steel-concrete composite support column are basically controlled by strength indicators. Since the outer wall of the steel tube of the steel-concrete composite column can withstand very high tensile stress, a large amount of steel reinforcement can be saved compared with traditional reinforced concrete columns.
