Description

Technical Field

[0001] This invention relates to the field of new energy technologies such as wind power and photovoltaics, specifically to a multi-stage limiting energy-consuming displacement amplification damping device and its application, which is suitable for use in support structures of wind power and photovoltaics to achieve energy consumption and vibration reduction under extreme working conditions. Background Art

[0002] In recent years, wind power development has achieved remarkable results both domestically and internationally as an effective measure to address the dual problems of energy scarcity and environmental pollution. However, with the increasing trend of wind power generation technology towards larger blades, higher power output, and taller towers, the overall reliability of wind turbine tower structures has become increasingly prominent. Excessive tower vibration and structural collapses are frequent occurrences, causing significant economic losses and severely impacting the wind power industry as a whole. In situations such as unusually strong winds or sudden loads, the external load on the tower increases abruptly, causing severe vibration and deformation of the tower, ultimately leading to tower collapse. Furthermore, excessive tower vibration can damage or loosen bolts at the lower flange, resulting in fatigue failure or fracture at the flange connection.

[0003] Based on the above problems, it is necessary to study a displacement amplification damping device that can realize multi-stage limit energy consumption in order to solve the above technical problems or mitigate their effects. Summary of the Invention

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention. Contents not described in detail in the embodiments of the present invention belong to the prior art known to those skilled in the art.

[0043] It should be noted that terms such as "first," "second," and "third" are merely for ease of description and distinction, and should not be interpreted as indicating or implying relative importance. Terms such as "up," "down," "front," "back," "left," "right," "inner," and "outer" are merely for ease of description and to establish relative orientations or positional relationships, and do not indicate or imply that the component referred to must have that specific orientation or position.

[0044] As the scale of individual buildings for new energy sources such as wind power and photovoltaics increases, both the wind turbine generators (RNA) and photovoltaic panels on the upper part become larger, and the requirements for the vibration resistance of the supporting structure also become higher. In addition, the probability of natural disasters is increasing, and energy projects are lifeline projects, so it is necessary to protect the supporting structure of existing new energy buildings against vibration.

[0045] This invention provides a displacement-amplifying damping device with multi-stage limiting energy dissipation. The damping device may include a fixing component, a connecting component, an energy dissipation component, and a force transmission component. The fixing component may include several limiting sleeves and several fixed connecting plates, with the limiting sleeves fixedly connected to the fixed connecting plates. The connecting component may include several limiting elements and several connecting members. The energy dissipation component may include several fan-shaped energy dissipation plates, which are hinged to the fixed connecting plates and mounted on the fixed connecting plates via limiting elements, enabling multi-stage limiting energy dissipation. The force transmission component may include several force transmission members, which are connected to the fan-shaped energy dissipation plates via connecting members and slidably connected to the limiting sleeves. The force transmission members can slide relative to the limiting sleeves within a certain set range along the force transmission direction.

[0046] In this invention, the force-transmitting component of the damping device slides relative to the limiting sleeve, transmitting force to the force-bearing end of the sector-shaped energy-dissipating plate through the connecting component. Because the sector-shaped energy-dissipating plate is hinged to the fixed connecting plate, the displacement of the force-bearing end of the sector-shaped energy-dissipating plate is amplified and transmitted to the damping end of the sector-shaped energy-dissipating plate through a lever principle. The sector-shaped energy-dissipating plate is mounted on the fixed connecting plate through a limiting member to form the damping end, enabling multi-stage limiting energy dissipation. Under normal operating conditions, the damping device does not participate in force bearing; under extreme operating conditions, the damping device participates in force bearing, achieving multi-stage limiting energy dissipation.

[0047] Exemplary Example 1

[0048] This exemplary embodiment provides a multi-stage limiting energy-consuming displacement amplification damping device. The following is in conjunction with... Figures 1 to 10 Describe it.

[0049] like Figures 1 to 4 As shown, the number of limiting sleeve 1, fixed connecting plate 2 and force transmission component 4 can all be 2, and the number of sector-shaped energy dissipation plate 3 and connecting component 7 can all be 4.

[0050] like Figures 1 to 6 As shown, two limiting sleeves 1 are symmetrically arranged laterally, and two fixed connecting plates 2 are symmetrically arranged vertically. The two limiting sleeves 1 and the two fixed connecting plates 2 together form a cross-shaped fixing frame with a central gap. Four sector-shaped energy-dissipating plates 3 are respectively installed on the front and rear surfaces of the two fixed connecting plates 2. Each sector-shaped energy-dissipating plate 3 may include a sector-shaped energy-dissipating section 31 and a handle connecting end 32. The sector-shaped energy-dissipating section 31 is installed on the fixed connecting plate 2, and the handle connecting end 32 is located near the center of the cross-shaped fixing frame. Two force-transmitting components 4 are arranged laterally, passing through the limiting sleeves 1. One end of the force-transmitting component 4, near the center of the cross-shaped fixing frame, is connected to the handle connecting end 32 of the sector-shaped energy-dissipating plate 3 via a connecting component 7.

[0051] Of course, the present invention is not limited to this. The number of limiting sleeve 1, fixed connecting plate 2 and force transmission component 4 can also be 1, 3, 4, etc., and the number of fan-shaped energy dissipation plate 3 and connecting component 7 can be matched according to the actual situation, as long as the corresponding multi-level limiting energy dissipation can be achieved. For example, when the number of limiting sleeve 1, fixed connecting plate 2 and force transmission component 4 is 3, the three fixed connecting plates 2 can be distributed at a 120° angle, and the three force transmission components 4 can also be distributed at a 120° angle, and each is connected to the outside to bear force.

[0052] In this embodiment, as Figure 1 and Figure 6 As shown, the fan-shaped energy-dissipating section 31 may include a first energy-dissipating section 3101 and a second energy-dissipating section 3102. The first energy-dissipating section 3101 is located outside the arc of the second energy-dissipating section 3102, and is farther away from the handle connection end 32 than the second energy-dissipating section 3102. During operation, it also experiences energy dissipation and vibration reduction before the second energy-dissipating section 3102. The first energy-dissipating section 3101 is generally arc-shaped and may be provided with a first slotted steel plate 3103; the second energy-dissipating section 3102 is also generally arc-shaped and may be provided with a second slotted steel plate 3104. The thickness of the first slotted steel plate 3103 is less than the thickness of the second slotted steel plate 3104, making the first slotted steel plate 3103 more prone to deformation and energy dissipation than the second slotted steel plate 3104. Of course, the invention is not limited to this; the fan-shaped energy-dissipating section 31 can also be designed as a three-stage, four-stage, or multi-stage energy-dissipating section according to actual needs.

[0053] Furthermore, the first slotted steel plate 3103 can be a rhomboid slotted steel plate, and the second slotted steel plate 3104 can be a shuttle-shaped slotted steel plate. The fan-shaped energy-consuming section 31, by using slotted steel plates of different thicknesses and shapes, facilitates better multi-level limiting energy consumption. Of course, the invention is not limited to this; the shapes of the first slotted steel plate 3103 and the second slotted steel plate 3104 can also be two other different shapes, such as square and circular, or triangular and elliptical.

[0054] In this embodiment, as Figures 1 to 6As shown, the first energy-consuming section 3101 has several first elongated holes 3105 along its arc-shaped edge, which are larger at both ends and smaller in the middle. The second energy-consuming section 3102 has several second elongated holes 3106 along its arc-shaped edge, which are larger at both ends and smaller in the middle. The length of the first elongated holes 3105 is shorter than the length of the second elongated holes 3106. The fixed connecting plate 2 has several first circular holes 201 and several second circular holes 202. The first circular holes 201 correspond one-to-one with the first elongated holes 3105, and the second circular holes 202 correspond one-to-one with the second elongated holes 3106. The size of the middle part of the first elongated holes 3105 and the second elongated holes 3106 is the same as the size of the first circular holes 201 and the second circular holes 202. The limiting member 6 can pass through the first circular holes 201 and the second circular holes 202.

[0055] Specifically, the number of first elongated holes 3105 and first circular holes 201 are the same and their positions correspond one-to-one, and the number of second elongated holes 3106 and second circular holes 202 are the same and their positions correspond one-to-one. All the first elongated holes 3105 are arranged in an arc shape, and all the second elongated holes 3106 are also arranged in an arc shape, and the corresponding first circular holes 201 and second circular holes 202 are also arranged in a corresponding arc shape. During installation, the middle part of the first elongated hole 3105 corresponds to the first circular hole 201, and the middle part of the second elongated hole 3106 corresponds to the second circular hole 202. The limiting member 6 passes through the first elongated hole 3105 of the front fan-shaped energy-consuming plate 3, the first circular hole 201 of the fixed connecting plate 2, and the first elongated hole 3105 of the rear fan-shaped energy-consuming plate 3 in sequence; similarly, the limiting member 6 also passes through the second elongated hole 3106 of the front fan-shaped energy-consuming plate 3, the second circular hole 202 of the fixed connecting plate 2, and the second elongated hole 3106 of the rear fan-shaped energy-consuming plate 3 in sequence. The length of the first long hole 3105 is shorter than the length of the second long hole 3106. This arrangement allows the first energy-consuming section 3101 to perform energy-consuming and vibration-damping before the second energy-consuming section 3102, so as to better achieve multi-level limit energy consumption.

[0056] In this embodiment, as Figure 1 , Figure 6 and Figure 10 As shown, the limiting member 6 may include a rod 601, two elastic members 602, and two limiting sliders 603. End caps may be provided at both ends of the rod 601. The limiting sliders 603 are sleeved on the rod 601, and the elastic members 602 are located between the end caps and the limiting sliders 603. The size of the rod 601 is the same as the middle size of the first elongated hole 3105 and the second elongated hole 3106, and the size of the limiting sliders 603 is the same as the end size of the first elongated hole 3105 and the second elongated hole 3106.

[0057] Specifically, when the sector-shaped energy-dissipating plate 3 is displaced due to the force transmission component 4, causing the ends of the first elongated hole 3105 / second elongated hole 3106 to correspond with the limiting slider 603, the elastic element 602 engages the limiting slider 603 with the ends of the first elongated hole 3105 / second elongated hole 3106, and the sector-shaped energy-dissipating plate 3 begins to be subjected to force for multi-stage limiting energy dissipation. The size and shape of the ends of the first elongated hole 3105 and second elongated hole 3106 match the limiting slider 603, and the ends of the first elongated hole 3105 and second elongated hole 3106 can be large circular holes.

[0058] Furthermore, the limiting member 6 can be a limiting bolt, wherein the rod body 601 can be a high-strength screw, and the elastic member 602 can be a prestressed spring. Of course, the present invention is not limited to this, and any other limiting member 6 that can achieve the above functions can be used.

[0059] In this embodiment, as Figures 1 to 6 , Figure 9 As shown, a first hinge hole 33 may be provided between the fan-shaped energy-consuming section 31 and the handle connecting end 32. The fixed connecting plate 2 may be provided with a second hinge hole 203 corresponding to the first hinge hole 33. The fixing assembly may also include two fixing plates 5, which are respectively arranged laterally on the front and rear sides of the limiting sleeve 1, and the left and right ends of the fixing plates 5 are respectively fixedly connected to two symmetrically positioned limiting sleeves 1. Two third hinge holes 501 may be provided vertically in the middle of the fixing plate 5, and the third hinge holes 501 correspond one-to-one with the first hinge holes 33. The connecting assembly may also include several hinge members 8, which are used to connect the first hinge hole 33, the second hinge hole 203, and the third hinge hole 501.

[0060] Specifically, the first hinge hole 33, the second hinge hole 203, and the third hinge hole 501 are the same size and their positions correspond one-to-one. During installation, the hinge member 8 passes sequentially through the third hinge hole 501 of the front fixing plate 5, the first hinge hole 33 of the front sector-shaped energy-consuming plate 3, the second hinge hole 203 of the fixing connecting plate 2, the first hinge hole 33 of the rear sector-shaped energy-consuming plate 3, and the third hinge hole 501 of the rear fixing plate 5. When the force transmission member 4 is subjected to force and the force is transmitted to the handle connection end 32 of the sector-shaped energy-consuming plate 3, the sector-shaped energy-consuming plate 3 can rotate around the hinge member 8. At this time, the hinge member 8 acts as the fulcrum for the sector-shaped energy-consuming plate 3 to perform multi-stage energy consumption using the lever principle. The fixing plate 5 has a thickened annular portion around the third hinge hole 501 on the side facing the sector-shaped energy-consuming plate 3 to facilitate better hinge function. The hinge member 8 can be a bolt, or other methods that can achieve this function.

[0061] In this embodiment, as Figures 1 to 5 , Figure 9As shown, the front and rear sides of the limiting sleeve 1 can be provided with a plurality of third circular holes 101 and two horizontally distributed limiting grooves 102. The left and right ends of the fixing plate 5 are both engaged between the limiting grooves 102, and the thickness of the fixing plate 5 is not greater than the protrusion height of the limiting grooves 102. The fixing plate 5 may also be provided with fourth circular holes 502 corresponding one-to-one with the third circular holes 101. The connecting assembly may also include a plurality of connectors 9, which are used to connect the third circular holes 101 and the fourth circular holes 502.

[0062] Specifically, the number of third circular holes 101 and fourth circular holes 502 are the same, and their positions and sizes correspond one-to-one. During installation, the connector 9 passes sequentially through the fourth circular hole 502 of the front fixing plate 5, the third circular hole 101 of the front of the limiting sleeve 1, the third circular hole 101 of the rear of the limiting sleeve 1, and the fourth circular hole 502 of the rear fixing plate 5 to achieve a fixed connection between the fixing plate 5 and the limiting sleeve 1. The limiting groove 102 protrudes outward, and the fixing plate 5 is formed between the upper and lower limiting grooves 102 to better achieve a fixed connection between the fixing plate 5 and the limiting sleeve 1.

[0063] In this embodiment, as Figures 1 to 8 As shown, the force transmission component 4 may include an end connecting plate 41, a middle square steel tube 42, and a top connecting plate 43, which are fixedly connected in sequence. The end connecting plate 41 is used to receive external forces; the size of the middle square steel tube 42 is consistent with the inner size of the limiting sleeve 1, and several horizontally arranged elongated holes 4201 are opened on both the front and rear sides of the middle square steel tube 42, and the elongated holes 4201 correspond one-to-one with the third circular hole 101; the top connecting plate 43 may be asymmetrically arranged, and the top connecting plate 43 is connected to the handle connecting end 32 through the connecting component 7 to transmit the force.

[0064] Specifically, the end connecting plate 41 is provided with several mounting holes 4101 for external connection, and the end connecting plate 41 and the central square steel pipe 42 can be fixedly connected by welding. The force transmission member 4 is provided with elongated holes 4201 to limit the sliding displacement of the force transmission member 4. The length of the elongated holes 4201 is the displacement range in which the force transmission member 4 can slide relative to the limiting sleeve 1. During installation, the connecting piece 9 also needs to pass through the elongated holes 4201 on both the front and rear sides of the central square steel pipe 42.

[0065] Furthermore, the top connecting plate 43 is provided with two first connecting holes 4301, each end of the connecting member 7 is provided with a second connecting hole 701, and the handle connecting end 32 is provided with a third connecting hole 3201. One end of the connecting member 7 is connected to the second connecting hole 701 and the third connecting hole 3201 by bolts, and the other end is also connected to the second connecting hole 701 and the first connecting hole 4301 by bolts. Of course, the present invention is not limited to this, and the connecting member 7 can be made in many ways, as long as it meets the requirements of high rigidity and can achieve the above functions.

[0066] Specifically, due to the asymmetrical arrangement of the top connecting plate 43, during installation, the force transmission component 4 at one end is connected to the handle connection ends 32 of the two fan-shaped energy-consuming plates 3 on one side via two connecting components 7. For example, the force transmission component 4 at the left end is connected to the handle connection ends 32 of the two fan-shaped energy-consuming plates 3 on the rear side via two connecting components 7, and the force transmission component 4 at the right end is connected to the handle connection ends 32 of the two fan-shaped energy-consuming plates 3 on the front side via two connecting components 7. This arrangement is to allow the force transmission component 4 to better undergo axial displacement within the limiting sleeve 1, and to allow the force transmission component 4 to be connected to the connecting components 7 via bolts. Furthermore, a second angle steel 4302 can be provided between the top connecting plate 43 and the middle square steel pipe 42. The two sides of the second angle steel 4302 are fixedly connected to both the top connecting plate 43 and the middle square steel pipe 42 by welding. The purpose is to increase the rigidity of the top connecting plate 43, and at the same time, to make the eccentric force due to the asymmetrical arrangement as consistent as possible with the axial force transmission.

[0067] In this embodiment, as Figure 4 and Figure 5 As shown, the limiting sleeve 1 is symmetrically provided with fixed connecting slots 103 on its upper and lower sides, and the fixed connecting plate 2 is placed in the connecting slots 103 and fixed therein. The end of the connecting slot 103 may be provided with a first angle steel 104, and the two sides of the first angle steel 104 are fixedly connected to the connecting slot 103 and the limiting sleeve 1 respectively.

[0069] Exemplary Example 2

[0070] This exemplary embodiment provides an application of a displacement amplification damping device with multi-stage limiting energy consumption.

[0071] The multi-stage limiting energy-consuming displacement amplification damping device of Exemplary Example 1 above is applied to the support structure of wind power photovoltaic to perform multi-stage limiting energy-consuming vibration reduction.

[0072] To better understand the above exemplary embodiments of the present invention, the following is in conjunction with... Figures 1 to 10 The assembly process of the displacement amplification damping device with multi-stage limit energy consumption is further explained.

[0073] The assembly process of the damping device includes, but is not limited to, the following steps:

[0074] (1) First, process the limiting sleeve 1, the fixing connecting plate 2, and the connecting slot 103. Then, weld the connecting slot 103 to the upper and lower symmetrical positions of the limiting sleeve 1. Next, align the through holes at the lower left and lower right ends of the fixing connecting plate 2 with the through holes in the connecting slot 103, and then connect them with bolts. Finally, weld the two sides of the first angle steel 104 to the connecting slot 103 and the limiting sleeve 1 respectively, thus completing the assembly of the fixing components (e.g., Figure 5 (As shown).

[0075] (2) Place the four processed sector-shaped energy-consuming plates 3 on the front and back sides of the fixed connecting plate 2 (e.g., Figure 1 (As shown). The limiting member 6 passes through the first elongated hole 3105 of the front fan-shaped energy-consuming plate 3, the first round hole 201 of the fixed connecting plate 2, and the first elongated hole 3105 of the rear fan-shaped energy-consuming plate 3 in sequence; similarly, the limiting member 6 also passes through the second elongated hole 3106 of the front fan-shaped energy-consuming plate 3, the second round hole 202 of the fixed connecting plate 2, and the second elongated hole 3106 of the rear fan-shaped energy-consuming plate 3 in sequence, thus completing the limiting installation of the fan-shaped energy-consuming plate 3 and the fixed connecting plate 2.

[0076] (3) Place the two processed force transmission components 4 into the limiting sleeves 1 at the left and right ends respectively. Connect the second connecting hole 701 at one end of the connecting component 7 to the third connecting hole 3201 in the sector-shaped energy dissipation plate 3 with bolts, and then connect the second connecting hole 701 at the other end of the connecting component 7 to the first connecting hole 4301 in the force transmission component 4 with bolts. Repeat this operation so that the four connecting components 7 connect the four sector-shaped energy dissipation plates 3 and the two force transmission components 4 (e.g., Figure 2 (As shown).

[0077] (4) Finally, install the two fixing plates 5 with the annular thickened part facing the fan-shaped energy dissipation plate 3. Use the hinge 8 to connect them by passing through the third hinge hole 501 of the front fixing plate 5, the first hinge hole 33 of the front fan-shaped energy dissipation plate 3, the second hinge hole 203 of the fixing connecting plate 2, the first hinge hole 33 of the rear fan-shaped energy dissipation plate 3, and the third hinge hole 501 of the rear fixing plate 5 in sequence. At the same time, use the connector 9 to connect them by passing through the fourth circular hole 502 of the front fixing plate 5, the third circular hole 101 of the front of the limiting sleeve 1, the elongated hole 4201 of the front of the force transmission component 4, the elongated hole 4201 of the rear of the force transmission component 4, the third circular hole 101 of the rear of the limiting sleeve 1, and the fourth circular hole 502 of the rear fixing plate 5 in sequence. This completes the assembly of the multi-stage limiting energy dissipation displacement amplification damping device (e.g., Figure 1 (As shown).

[0078] In summary, the damping device of this invention amplifies displacement through a simple lever principle, employs two types of slotted steel plates with different thicknesses and shapes, and achieves multi-level limiting energy dissipation through different limiting settings. This damping device, with its elongated holes (large at both ends and small in the middle) engaging with limiting components, allows it to remain unaffected by small displacements in the force-transmitting component. Only under extreme conditions, when the displacement of the force-transmitting component increases due to the original structure, causing the limiting slider in the limiting component to engage with the fan-shaped energy-dissipating plate, does the device begin to bear force and dissipate energy for vibration reduction.

[0079] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should fall within the scope of protection of the technical solution of the present invention.
