Abstract

This invention provides a hybrid structure solar thermal power generation tower with a multi-stage energy-dissipating self-resetting section, belonging to the field of solar thermal power generation technology. It includes an upper steel truss, a lower concrete cylinder, and a self-resetting section. The self-resetting section is equipped with a multi-stage self-resetting damper.

When the relative displacement between the two connecting members exceeds a preset threshold, the first energy-dissipating component dissipates energy through material yielding. The second energy-dissipating component includes a motion conversion mechanism and a reset component. The motion conversion mechanism converts the relative displacement between the two connecting members into a driving force on the reset component, causing it to store energy through elastic deformation under the driving force and release the energy to drive the reset when the driving force disappears.

Description

Technical Field

[0001] This invention belongs to the field of solar thermal power generation technology, specifically relating to a hybrid structure heat absorption tower with a multi-stage energy-consuming self-resetting section. Background Technology

[0002] As the core component of a concentrated solar power (CSP) plant, the solar thermal tower is structurally tall, with the receiver and supporting heavy-duty equipment at the top weighing thousands of tons, forming a towering structural system characterized by "high flexibility and heavy load at the top." Due to the stringent positioning accuracy requirements of the concentrating system, changes in the displacement of the top of the solar thermal tower directly affect the concentrating efficiency, making the lateral stiffness of the tower a core indicator in structural design. To meet this technical requirement, solar thermal towers typically employ a hybrid structure: a lower, more rigid concrete cylinder structure to control overall displacement, and an upper steel truss structure for easier equipment installation.

[0003] In traditional solar absorber towers, there is a sudden change in stiffness and mass at the transition section between the concrete cylinder and the steel truss cylinder. The stress state in this area is complex, and it is prone to become a weak point in the structure during earthquakes, which seriously threatens the safety of the structure and equipment. Furthermore, excessive residual deformation after an earthquake can cause the concentrating system to become inaccurate, resulting in a significant decrease in the power plant's power generation efficiency or even shutdown.

[0004] Therefore, it is necessary to provide a hybrid structure heat absorption tower with a configuration of multi-stage energy-consuming self-resetting sections to solve the above problems. Summary of the Invention

[0005] This invention provides a hybrid structure heat absorption tower with a multi-stage energy-consuming self-resetting section. It achieves multi-stage energy consumption through the cooperation of two energy-consuming components and reduces post-earthquake residual deformation by utilizing the self-resetting characteristics of the reset component. This solves the problems of insufficient energy consumption capacity of the conversion section and excessive post-earthquake residual deformation in the prior art.

[0006] To solve the above-mentioned technical problems, the present invention is implemented as follows: A hybrid structure heat absorption tower with a multi-stage energy-dissipating self-resetting section includes an upper steel truss, a lower concrete cylinder, and a self-resetting section disposed between the upper steel truss and the lower concrete cylinder. The self-resetting section is equipped with at least one multi-stage self-resetting damper, which includes: Two connectors are respectively connected to the upper steel truss and the lower concrete cylinder; A first energy-dissipating component is connected between the two connecting members. When the relative displacement between the two connecting members exceeds a preset threshold, the first energy-dissipating component dissipates energy through material yielding. At least one second energy-consuming component is arranged side by side with the first energy-consuming component, and includes: Reset component; A motion conversion mechanism, connected to one of the connecting members, is used to convert the relative displacement between the two connecting members into a driving force on at least one reset component. The reset component stores energy through elastic deformation under the driving force and releases the stored energy to drive the connected connecting member and the motion conversion mechanism to reset when the driving force decreases or disappears.

[0007] As a preferred improvement, the two connectors are divided into a first connector and a second connector, and the first energy-dissipating component includes: The substrate is fixedly connected to the first connector. An energy-consuming board is stacked on top of the substrate, with one end slidably connected to the first connector and the other end fixedly connected to the second connector; When the relative displacement between the first connector and the second connector exceeds a preset threshold, the energy dissipation plate dissipates energy through material yielding.

[0008] As a preferred improvement, one end of the energy-consuming board has a transverse elongated hole extending along its length, and a sliding member is fixed on the first connector. The sliding member passes through the transverse elongated hole to realize the sliding connection between the first connector and the energy-consuming board.

[0009] As a preferred improvement, the motion conversion mechanism includes: The core board is fixedly connected to the second connector; At least one cover plate is stacked on top of the core plate and can slide relative to it; In this embodiment, one of the two surfaces of the core plate and the cover plate opposite each other is provided with a wedge-shaped block protruding from it, and the other surface is provided with a wedge-shaped groove that wedges into the wedge-shaped block; the wedge-shaped block is housed in the wedge-shaped groove to convert the relative linear motion between the core plate and the cover plate into a thrust that drives the cover plate toward the reset assembly.

[0010] As a preferred improvement, the motion conversion mechanism includes two cover plates, with the core plate sandwiched between the two cover plates; both sides of the core plate are provided with the wedge-shaped blocks, and both cover plates are provided with the wedge-shaped grooves.

[0011] As a preferred improvement, the reset component includes: At least one high-strength bolt passes through the motion conversion mechanism; At least one ring spring assembly is sleeved on both ends of the high-strength bolt; The nut is locked to the end of the high-strength bolt and clamps the ring spring assembly between the nut and the motion conversion mechanism.

[0012] As a preferred improvement, the ring spring assembly includes an inner ring and an outer ring; the outer ring has a central hole, which is formed by two axially symmetrical tapered segments with gradually decreasing opening areas towards the center; each tapered segment is fitted with an inner ring, and the outer tapered surface of the inner ring fits against the inner tapered surface of the tapered segment.

[0013] As a preferred improvement, the second energy-consuming component further includes a limiting mechanism, which is fixed to the substrate and disposed at both ends of the cover plate to limit the lateral displacement of the cover plate.

[0014] As a preferred improvement, there are multiple multi-stage self-resetting dampers, which are arranged in a ring array along the circumference of the heat absorption tower; each multi-stage self-resetting damper has two sets of the second energy dissipation components, which are symmetrically distributed on both sides of the first energy dissipation components.

[0015] As a preferred improvement, the inner wall of the top of the lower concrete cylinder is provided with an I-shaped mounting groove, which includes an upper transverse groove, a lower transverse groove, and a vertical groove connecting the two. The multi-stage self-resetting damper is housed in the vertical groove, and its top is connected to the upper steel truss cylinder through an upper auxiliary fixing member, and its bottom is connected to the lower concrete cylinder through a lower auxiliary fixing member. The top of the upper auxiliary fixing member is fixedly connected to the upper steel truss cylinder, and its side is slidably connected to the lower concrete cylinder through a vertically extending elongated hole and a movable bolt. The self-resetting section also includes a metal rubber support, which is disposed between the upper auxiliary fixing member and the groove wall of the upper transverse groove.

[0016] The beneficial effects of this invention are as follows: (1) The present invention has a multi-level energy dissipation effect: when the magnitude is less than or equal to the critical value, a certain buffering effect is achieved through the deformation of the metal rubber bearing, the relative slippage of the cover plate and the core plate within a certain range, and the compression of the reset component. The energy input by the earthquake is absorbed and dissipated through deformation and friction. When the magnitude is greater than the critical value, the energy dissipation plate is activated and begins to yield, further participating in energy dissipation and vibration reduction to improve the energy dissipation characteristics under strong earthquakes. (2) The present invention has a self-resetting effect: the ring spring assembly is made of high-strength spring steel, which can restore to the initial state after bearing a high intensity load. During the reset process of the ring spring assembly, it drives the overall structure to reset, reduces the residual deformation of the structure, and thus reduces the repair cost and difficulty after the earthquake. (3) The present invention has the advantages of easy installation and disassembly and quick repair. The present invention concentrates structural energy consumption and yielding on replaceable components. After structural damage, repair work can be carried out quickly, which meets the need for rapid functional recovery of the heat absorption tower after a strong earthquake disaster.

[0017] In summary, this invention uses a multi-stage self-resetting damper and a metal-rubber bearing as protective components for a hybrid structure heat absorption tower under seismic loads. This achieves multi-stage energy dissipation with high redundancy, ensuring the heat absorption tower's excellent vibration reduction and energy dissipation characteristics. It also has the advantages of good self-resetting capability and easy replacement and repair, which can effectively improve the seismic performance of the hybrid structure heat absorption tower.

Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figure 1As shown, this embodiment provides a hybrid structure solar thermal power plant with a multi-stage energy-consuming self-resetting section. It is used in conjunction with heliostats and receivers as the core component of the solar thermal power plant. Its basic operation process is as follows: multiple heliostats are set up around the solar thermal power plant. By tracking the sun, the direct solar radiation is reflected and concentrated onto the receiver at the top of the solar thermal power plant to absorb solar energy. Then, through subsequent energy conversion, the solar energy is converted into electrical energy.

[0021] The hybrid structure heat absorption tower includes an upper steel truss 3, a lower concrete cylinder 4, and a self-resetting section disposed between the two. At least one multi-stage self-resetting damper 1 is configured within the self-resetting section. Both the upper steel truss 3 and the lower concrete cylinder 4 adopt conventional structures in the art. The lower concrete cylinder 4 has high rigidity to control overall displacement. The upper steel truss 3 is composed of a steel structure, facilitating the installation and fixing of the heat absorber and other related components. The two ends of the multi-stage self-resetting damper 1 are connected to the upper steel truss 3 and the lower concrete cylinder 4, respectively.

[0022] To install the multi-stage self-resetting damper 1, an I-shaped mounting groove 40 is provided on the inner wall of the top of the lower concrete cylinder 4. This mounting groove 40 consists of an upper transverse groove 41, a lower transverse groove 42, and a vertical groove 43 connecting the two. The main body of the multi-stage self-resetting damper 1 is housed within the vertical groove 43. The bottom of the multi-stage self-resetting damper 1 is fixedly connected to the lower transverse groove 42 via a lower auxiliary fixing member 45. The top of the multi-stage self-resetting damper 1 is connected to the upper steel truss cylinder 3 via an upper auxiliary fixing member 44. The top of the upper auxiliary fixing member 44 is fixedly connected to the upper steel truss cylinder 3, and its side, through a vertical elongated hole and a movable bolt 46, forms a vertically sliding connection with the lower concrete cylinder 4 to accommodate displacement during damper operation. In addition, the self-resetting section also includes a metal rubber support 2, which is disposed between the upper auxiliary fixing member 44 and the groove wall of the upper transverse groove 41, serving as a primary energy dissipation element under micro-vibration or wind vibration. The number of metal rubber supports 2 is selected according to actual needs.

[0023] Preferably, there are multiple multi-stage self-resetting dampers 1, which are arranged in a ring array along the circumference of the heat absorption tower to uniformly provide energy dissipation around the tower. In actual construction, the number of multi-stage self-resetting dampers 1 is determined based on the energy consumption requirements of the installation environment.

[0024] like Figures 2-4As shown, the multi-stage self-resetting damper 1 includes a first connector, a second connector, a first energy dissipation component 10, and two sets of second energy dissipation components 20. The two sets of second energy dissipation components 20 are symmetrically arranged on both sides of the first energy dissipation component 10. In this embodiment, the first connector is a fixed lug 13, the second connector is a movable lug 14, the upper auxiliary fixing component 44 is fixed to the upper steel truss 3 and is considered part of the upper steel truss 3, the lower auxiliary fixing component 45 is fixed to the lower concrete cylinder 4 and is considered part of the lower concrete cylinder 4, the fixed lug 13 is hinged to the lower auxiliary fixing component 45, and the movable lug 14 is hinged to the upper auxiliary fixing component 44. Under seismic action, the relative movement between the upper steel truss 3 and the lower concrete cylinder 4 will drive the damper to work through this hinge point. In other embodiments, the installation positions of the fixed lug 13 and the movable lug 14 can also be interchanged.

[0025] The first energy-consuming component 10 includes two parallel spaced substrates 12 and an energy-consuming plate 11 sandwiched between the two substrates 12, which together form a stacked structure. The fixed ear plate 13 is integrally formed or fixedly connected to one end of the substrate 12, and the movement states of the two are consistent; the movable ear plate 14 is spaced apart at the other end of the substrate 12, and the movement states of the two are independent of each other.

[0026] One end of the energy-consuming plate 11 is movably connected to the fixed ear plate 13, and the other end is fixedly connected to the movable ear plate 14. It includes an energy-consuming plate body 111, and movable connecting portions 112 and fixed connecting portions 113 integrally formed with the energy-consuming plate body 111 at both ends. The energy-consuming plate body 111 is sandwiched between the two base plates 12, the movable connecting portion 112 is sandwiched between the two fixed ear plates 13 and connected to the fixed ear plates 13 via a sliding member 15, and the fixed connecting portion 113 is sandwiched between the two movable ear plates 14 and fixed to the movable ear plates 14 via bolts.

[0027] Specifically, a transverse elongated hole 1120 is provided through the upper edge of the movable connecting part 112, and the transverse elongated hole 1120 is along... Figure 2 Extending along the X-axis, the two ends of the slider 15 are anchored to the fixed ear plate 13, and the middle position passes through the transverse elongated hole 1120. The rod of the slider 15 passes through the transverse elongated hole 1120, and the diameter of the rod is smaller than the width of the transverse elongated hole 1120, so that the movable connecting part 112 can slide linearly relative to the fixed ear plate 13.

[0028] The movable ear plate 14 includes a first fixing plate 141 and a second fixing plate 142 arranged vertically. The first fixing plates 141 of the two movable ear plates 14 are parallel and spaced apart. The fixed connection part 113 is sandwiched between the first fixing plates 141 of the two movable ear plates 14 and is fastened by bolts so that the fixed connection part 113 and the movable ear plate 14 maintain the same movement state.

[0029] The width of the energy-consuming panel body 111 is smaller than the width of the movable connecting part 112 and the fixed connecting part 113, forming an "I" shape that is narrow in the middle and wide at both ends. This structural form can ensure the effective area of ​​the movable connecting part 112 and the fixed connecting part 113 for better docking with other components; on the other hand, it can also control the yielding position on the energy-consuming panel body 111.

[0030] like Figure 2 , Figure 3 , Figures 5-9 As shown, the second energy-consuming component 20 is arranged side by side with the first energy-consuming component 10, that is, the second energy-consuming component 20 is disposed on the side of the substrate 12 away from the energy-consuming plate 11, and includes a motion conversion mechanism 21, a limiting mechanism 22, and a reset component 23. Two sets of the second energy-consuming component 20 are provided, symmetrically located on both sides of the first energy-consuming component 10.

[0031] The motion conversion mechanism 21 includes two spaced-apart cover plates 212 and a core plate 211 sandwiched between the two cover plates 212 and capable of sliding relative to the cover plates 212. Structurally, the cover plates 212 and the core plate 211 are along... Figure 2 The layers are stacked along the Y-axis as shown. The limiting mechanism 22 is fixed to the side of the substrate 12 away from the energy-consuming plate 11. Each end of the cover plate 212 abuts against one of the limiting mechanisms 22. One end of the core plate 211 is a free end, and the other end is fixed to the movable ear plate 14. The core plate 211 protrudes towards the cover plate 212 to form a wedge block 2110. The cover plate 212 is provided with a wedge groove 2120 corresponding to the position of the wedge block 2110. The wedge block 2110 is received in the wedge groove 2120. The number of wedge blocks 2110 is set to be multiple, and the wedge groove 2120 is provided one-to-one with the wedge block. The wedge block 2110 is received in the wedge groove 2120, and the inclined surfaces of the two are in contact with each other. When the core plate 211 moves along the X-axis, the wedge block 2110 drives the cover plate 212 to move in a direction perpendicular to the substrate 12 (Y-axis).

[0032] Each core plate 211 has a core plate fixing part 2111 at its end near the movable ear plate 14 for fixing to the second fixing plate 142 by means of bolt fixing.

[0033] Since the core plate 211 is sandwiched between the two cover plates 212, the core plate 211 is provided with wedge blocks 2110 on both sides along the Y-axis, which can synchronously drive the two cover plates 212 to move along the Y-axis.

[0034] The limiting mechanism 22 is fixed to the substrate 12 by welding. The limiting mechanism 22 includes a first plate 221 fixed to the substrate 12 and a second plate 222 connected to the first plate 221 and parallel to the substrate 12. The cover plate 212 is sandwiched between the two first plates 221 at both ends along the X-axis and between the second plate 222 and the substrate 12 on both sides along the Z-axis. This structural design restricts the movement of the cover plate 212 along both the X-axis and Z-axis, allowing it to maintain only a single movement along the Y-axis.

[0035] The reset assembly 23 includes a high-strength bolt 231, a nut 232, and multiple ring spring assemblies 233. The high-strength bolt 231 passes sequentially along the Y-axis through a cover plate 212, a core plate 211, and another cover plate 212. Both ends of the high-strength bolt 231 extend out of the cover plate 212 and are fitted with ring spring assemblies 233. Finally, the nut 232 locks the bolt in place, clamping the ring spring assemblies 233 between the nut 232 and the cover plate 212. A preload can be applied to the ring spring assemblies 233 by adjusting the nut 232. Multiple reset assemblies 23 are arranged at equal intervals along the X-axis.

[0036] It is understood that both the cover plate 212 and the core plate 211 have through holes along the Y-axis for the high-strength bolts 231 to pass through. Furthermore, since the core plate 211 also needs to move along the X-axis, the through holes on the core plate 211 need to be elongated straight holes 2113. The length of the elongated straight hole 2113 along the X-axis is not less than the length of the transverse elongated hole 1120, to avoid constraining the movement of the core plate 211 along the X-axis. Moreover, the elongated straight hole 2113 is located on the wedge block 2110 to fully utilize the advantage of the larger thickness of the core plate 211 at that location, reducing the impact of the opening on the strength of the core plate 211.

[0037] like Figures 6-7 As shown, the ring spring assembly 233 includes an inner ring 2331 and an outer ring 2332. The central hole of the outer ring 2332 is formed by two symmetrical tapered segments 2333 connected together. An inner ring 2331 is fitted into each tapered segment 2333, and the outer tapered surface of the inner ring 2331 is in close contact with the inner tapered surface of the tapered segment 2333. The axial thickness of the inner ring 2331 is slightly greater than the axial depth of the tapered segment 2333, ensuring that the inner ring 2331 undergoes radial contraction and axial expansion under preload or compression, generating a strong elastic restoring force.

[0038] By adjusting parameters such as the preload of the reset assembly 23, the number of reset assemblies 23, the number of ring spring assemblies 233, the friction coefficient of each contact surface in the friction energy dissipation, and the inclined angle of the wedge block 2110, the energy dissipation performance of the multi-stage self-resetting damper 1 can be precisely controlled, thereby flexibly adapting to the energy dissipation requirements under different working conditions.

[0039] The energy dissipation principle of the multi-stage self-resetting damper 1 is as follows: Under the action of an earthquake, the upper steel truss 3 and the lower concrete cylinder 4 vibrate, and the vibration is transmitted to the multi-stage self-resetting damper 1 through the fixed ear plate 13 and the movable ear plate 14. First, the core plate 211 is driven to move along the X-axis. The relative sliding between the core plate 211 and the cover plate 212 can form frictional energy dissipation, which is the first stage of energy dissipation.

[0040] Since the contact surfaces of the wedge block 2110 and the wedge groove 2120 are inclined, the sliding distance can be decomposed into a component in the Y-axis direction, driving the cover plate 212 to generate displacement in the Y-axis direction. This displacement, in conjunction with the nut 232, compresses the ring spring assembly 233. The inner ring 2331 and outer ring 2332 of the ring spring assembly 233 generate friction and deformation energy dissipation, serving as secondary energy dissipation. After the seismic action is eliminated, the system can automatically return to its original state under the drive of the restoring force of the ring spring assembly 233, thus achieving a self-resetting function.

[0041] Furthermore, during the displacement process, the energy-dissipating plate 11 and the substrate 12 undergo relative displacement. During this process, the sliding member 15 moves synchronously within the transverse elongated hole 1120 to accommodate the movement of the energy-dissipating plate 11. Due to the limited length of the transverse elongated hole 1120, the energy-dissipating plate 11 cannot generate further displacement after reaching the end of its stroke. As the vibration intensifies, the energy-dissipating plate 11 is activated and begins to gradually yield, dissipating energy through deformation as a third-level energy dissipation.

[0042] In short, when the magnitude is less than or equal to the critical value, a certain buffering effect is achieved through the deformation of the metal rubber bearing 2, the relative slippage of the cover plate 212 and the core plate 211 within a certain range, and the compression of the ring spring assembly 233, absorbing and dissipating the energy input by the earthquake through deformation and friction. When the magnitude exceeds the critical value, the energy-dissipating section further participates in energy dissipation and vibration reduction through the yielding of the energy-dissipating plate 11, thereby improving the energy dissipation characteristics under strong earthquakes and achieving a multi-stage energy dissipation effect.

[0043] This invention uses a multi-stage self-resetting damper and a metal-rubber bearing as protective components for a hybrid structure heat absorption tower under seismic loads. It achieves multi-stage energy dissipation with high redundancy, ensuring the heat absorption tower's excellent vibration reduction and energy dissipation characteristics. It also has the advantages of good self-resetting capability and easy replacement and repair, which can effectively improve the seismic performance of the hybrid structure heat absorption tower.

[0044] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other modifications under the guidance of the present invention without departing from the spirit of the present invention, and all of these modifications are within the protection scope of the present invention.
