Description

Technical Field

[0001] The present invention relates to the technical field of wind turbine generators, and more particularly to a platform inside a tower of a wind turbine generator. Background Art

[0002] For large offshore wind turbine generators, in order to reduce costs, the wall thickness of the tower is getting thinner and thinner. Since the wall thickness of the tower is relatively thin and the size is relatively large, when the tower is placed in a horizontal state for installing related components, the tower will deform due to its own weight and thus assume an oval shape, unable to maintain the theoretically circular shape, which will cause difficulties in installing the platform inside the tower.

[0003] For example, when the tower becomes oval due to deformation, it cannot adapt to the shape and size of the platform, resulting in difficult and inefficient platform installation operations. At the same time, when the tower is rotated during the platform installation process, at certain angles, due to the large deformation amount of the tower, there will also be problems such as excessive local stress on the tower wall or the need to rework due to the platform being cracked.

[0004] Therefore, in the prior art, there are often phenomena of delaying the construction period due to problems such as low platform installation efficiency and poor reliability. Summary of the Invention

[0005] One of the purposes of the present invention is to provide a floating platform, which solves problems such as difficult platform installation and poor platform reliability, and significantly improves the installation efficiency and reliability of the platform.

[0006] According to one aspect of the invention, there is provided a floating platform, including: a central floating body located at the center of the floating platform; and a plurality of connecting beam groups respectively connected to the outer periphery of the central floating body and respectively extending radially outward from the central floating body in different directions in a plane parallel to the floating platform, wherein each connecting beam group includes an elastic component capable of stretching and contracting along the extending direction of the connecting beam group.

[0007] Optionally, the connecting beam group may include radial cross beams, one end of the elastic component may be connected to the radial cross beam, and the other end may be connected to the central floating body. The connecting beam group may further include a sliding component capable of sliding along the extending direction of the connecting beam group, one end of the sliding component may be fixedly connected to one of the central floating body and the radial cross beam, and the other end may be slidably supported by the other of the central floating body and the radial cross beam.

[0008] Optionally, the floating platform may further include a support base and a sliding assembly. The connecting beam group may include radial cross beams connected to the central floating body. One end of the elastic assembly may be connected to the radial cross beam, and the other end may be connected to the support base. One end of the sliding assembly may be fixedly connected to one of the radial cross beam and the support base, and the other end may be slidably supported by the other of the radial cross beam and the support base.

[0009] Optionally, the sliding assembly may include at least one of a screw, a sleeve assembly, and a bushing assembly.

[0010] Optionally, the elastic assembly may include at least one of a combination of elastic rubber and a tension spring and a compression-tension spring.

[0011] Optionally, a plurality of the connecting beam groups may be symmetrically arranged relative to the central floating body.

[0012] Optionally, the central floating body may be annular as a whole. The central floating body may include an annular cylindrical wall. The elastic assembly may include a spring and a first connecting plate and a second connecting plate connected to both ends of the spring. The first connecting plate may be connected to a first support plate at the end of the radial cross beam, and the second connecting plate may be connected to the annular cylindrical wall.

[0013] Optionally, the sliding assembly may include at least two screws. The first end of the screw may be fixedly connected to the first support plate. Screw end support holes may be formed in the annular cylindrical wall, and the second end of the screw may be inserted into the screw end support holes.

[0014] Optionally, the connecting beam group further includes a clearance adjusting member. The clearance adjusting member includes an adjusting nut screwed onto the second end of the screw, and the adjusting nut abuts against the radial inner surface of the annular cylindrical wall or the second connecting plate.

[0015] Optionally, the connecting beam group may further include a clearance adjusting member. The clearance adjusting member may include a connecting bolt and an adjusting nut. One end of the connecting bolt may be connected to the spring, the second end of the connecting bolt may pass through the annular cylindrical wall and be connected to the adjusting nut, and the adjusting nut may abut against the radial inner surface of the annular cylindrical wall.

[0016] According to the floating platform of the present invention, the installation of the platform can be conveniently and efficiently realized. By applying the elastic assembly, the impact of external deformation force on the platform can be absorbed, avoiding problems such as platform tearing or excessive local stress. At the same time, by applying the sliding assembly, the bending load-bearing capacity of the platform can be improved, and the installation connection of the floating platform can be easily realized through the cooperation of the clearance adjusting member and the elastic assembly. Therefore, the adaptive adjustment ability of the platform can be significantly improved, and the installation efficiency and reliability of the platform can be improved.

Detailed implementation manners

[0030] In order to enable those skilled in the art to better understand the present invention, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] An in-tower platform may be installed in the tower barrel 20 of the wind turbine generator set, and an elevator opening 30 and a ladder opening 40 may be provided on the platform to facilitate the operation of the operator inside the tower barrel.

[0032] According to an embodiment of the present invention, a floating platform 100 is provided, which can be easily installed to adapt to the deformation of the tower barrel 20 and absorb the deformation force of the tower barrel 20 after installation, and thus has higher reliability.

[0033] Figure 1 It is a schematic diagram showing the connection structure of the floating platform 100.

[0034] Refer to Figure 1 , the floating platform 100 includes: a central floating body 120, the central floating body 120 is located at the center of the floating platform 100; and a plurality of connecting beam groups 130, the plurality of connecting beam groups 130 are respectively connected to the outer periphery of the central floating body 120, and respectively extend radially outward from the central floating body 120 in different directions in a plane parallel to the floating platform 100.

[0035] The floating platform 100 according to the present invention may further include a platform panel, and the platform panel may be directly laid on the connecting beam group 130 after the plurality of connecting beam groups 130 extending radially as described above are installed on the inner wall of the tower barrel. Therefore, it is not necessary to directly connect the platform panel to the inner wall of the tower barrel 20, which reduces the installation difficulty of the platform panel, and can prevent the platform panel from being torn or the local stress of the platform / tower barrel 20 from being too large.

[0036] The connecting beam group 130 may include an elastic component (for example, Figure 2 the spring seat including the spring 131 shown in

[0037] The extension length of the connecting beam group 130 can be adjusted by the expansion and contraction of the elastic component. Therefore, the assembly of the floating platform 100 according to the embodiment of the present invention can be easily installed without being affected by the large deformation of the tower barrel.

[0038] That is, even when the tower barrel 20 changes from a perfect circle to an ellipse when the tower barrel 20 is placed horizontally, the radial clearance or insufficient radial installation space caused by the deformation of the tower barrel 20 can be adapted by adjusting the expansion and contraction state of the elastic component, so that the platform can still be assembled smoothly.

[0039] In addition, even during the process of rotating the tower barrel 20 from a horizontal state to a vertical state after the floating platform 100 is installed, through the expansion and contraction of the elastic component, the floating platform 100 can also adapt to the radial tensile force or extrusion force exerted on the floating platform 100 due to the deformation of the tower barrel 20.

[0040] That is, the floating platform 100 can automatically adapt to the deformation of the tower barrel 20 without defects such as platform tearing or excessive local stress, thereby effectively ensuring the stability and reliability of the platform.

[0041] The central floating body 120 can be located at the center of the floating platform 110, and multiple connecting beam groups 130 can be symmetrically arranged relative to the central floating body 120. Through this symmetric centripetal design, the floating platform system can be free from the action of additional bending moments.

[0042] The connecting beam group 130 may further include a radial cross beam 132. The radial cross beam 132 can be made of profiles for supporting and connecting the elastic component.

[0043] One end of the elastic component can be connected to the radial cross beam 132, and the other end can be connected to the central floating body 120.

[0044] Figure 2 Yes Figure 1 is an enlarged view of part I, showing an example of the connection structure of the elastic component according to this embodiment.

[0045] Refer to Figure 1 And Figure 2 As an example, when the elastic component is implemented as a spring seat, the elastic component may include a spring 131 and a first connecting plate 138 and a second connecting plate 137 connected to both ends of the spring 131. As an example, the spring 131 can be a tension-compression spring.

[0046] A first support plate 139 may be provided at the end of the radial cross beam 132. The first connecting plate 138 can be connected to the first support plate 139 at the end of the radial cross beam 132, and the second connecting plate 137 can be connected to the annular cylindrical wall 123 (which will be described in detail below with reference to Figures 10 to 12 ) of the central floating body 120.

[0047] Refer toFigure 2 The first connecting plate 138 and the second connecting plate 137 can be fixedly connected to the radial cross beam 132 and the central floating body 120 respectively through connecting bolts 135.

[0048] Figure 3 It is along Figure 1 the sectional view taken along A-A of Figure 4 which shows an example of the connection structure of the floating platform 100. Figure 3 It is an enlarged view of part J in

[0049] According to this embodiment, the connecting beam group 130 may further include a sliding component (for example, Figure 4 the screw 133 shown in

[0050] ). The sliding component can slide along the extending direction of the connecting beam group 130 (i.e., the telescopic direction of the elastic component) to slidably guide and support the telescoping of the elastic component.

[0051] One end of the sliding component can be fixedly connected to one of the central floating body 120 and the radial cross beam 132, and the other end can be slidably supported by the other of the central floating body 120 and the radial cross beam 132.

[0052] Referring to Figure 3 and Figure 4 as an example, the sliding component may include at least two screws 133. The first end of the screw 133 can be a fixed end 142 and is fixedly connected through a nut. The second end of the screw 133 can be a sliding end 141.

[0053] Figure 4 shows an example where the fixed end 142 is fixedly connected to the first support plate 139 and the sliding end 141 is slidably supported by the central floating body 120. For example, the sliding end 141 is inserted into the screw end support hole 122 (refer to Figure 11 ) and is slidably supported by the screw end support hole 122.

[0054] That is to say, the screw end support hole 122 can be formed on the annular cylinder wall 123 of the central floating body 120, and the second end of the screw 133 can be inserted into the screw end support hole 122.

[0055] However, the setting of the sliding support direction of the screw 133 of the sliding component is not limited to the above description. As another example, the fixed end 142 of the screw 133 can also be fixedly connected to the central floating body 120. At the same time, a screw end support hole is formed on the first support plate 139 at the end of the radial cross beam 132, so as to slidably support the sliding end 141 of the screw 133 through the radial cross beam 132.

[0056] Figures 1 to 4 An example in which the elastic component and the sliding component are arranged adjacent to the central floating body 120 is shown, that is, an example in which the elastic component and the sliding component are located between the radial cross beam 132 and the central floating body 120.

[0057] In this case, the other end of the radial cross beam 132 can be connected to the support seat 110 on the tower wall (refer to Figure 6 ), and the support seat 110 can be arranged on the inner wall of the tower 20 by welding, for example (hereinafter, the specific structure of the support seat 110 will be described in detail with reference to Figure 8 and Figure 9 ).

[0058] However, the installation positions of the elastic component and the sliding component are not limited to Figures 1 to 4 the example shown in. As another example, the elastic component and / or the sliding component can be arranged adjacent to the inner wall of the tower, that is, the elastic component and / or the sliding component are arranged between the radial cross beam 132 and the support seat 110.

[0059] In this case, one end of the elastic component can be connected to the support seat 110, and the other end can be connected to the radial cross beam 132. One end of the radial cross beam 132 can be connected to the elastic component, and the other end can be connected to the central floating body 120.

[0060] Accordingly, one end of the sliding component can be fixedly connected to one of the radial cross beam 132 and the support seat 110, and the other end can be slidably supported by the other of the radial cross beam 132 and the support seat 110.

[0061] As yet another example, the elastic component and the sliding component can be located in the middle section area of the connecting beam group 130, without being adjacent to the central floating body 120 or the inner wall of the tower 20.

[0062] In this case, one connecting beam group 130 of the floating platform 100 can include two radial cross beams. One radial cross beam can be connected to the support seat, and the other radial cross beam can be connected to the central floating body, and the elastic component and the sliding component are placed between the two radial cross beams.

[0063] In this case, the two ends of the elastic component and the sliding component can be respectively connected and supported by the two radial cross beams.

[0064] The connecting beam group 130 may further include a gap adjusting member. By means of the gap adjusting member, the telescoping of the elastic component can be adjusted, so as to utilize the telescoping of the elastic component to adapt to the deformation of the tower barrel.

[0065] For example, the gap can be eliminated by the elongation of the elastic component, or the problem of insufficient radial installation space can be adapted by the compression of the elastic component, so as to avoid the problem that it is difficult to install during the installation of the floating platform due to the existence of installation gaps or insufficient installation space.

[0066] As an example, the gap adjusting member may include an adjusting nut screwed onto the second end of the screw 133, so as to adjust the telescoping state of the elastic component by screwing the adjusting nut, thereby adapting to the problem that it is difficult to install due to the deformation of the tower barrel 20 during the installation of the floating platform 100.

[0067] The adjusting nut can abut against the radially inner surface of the annular barrel wall 123 of the central floating body 120 and / or the second connecting plate 137.

[0068] Refer to Figure 4 , when the adjusting nut 136 located on the second connecting plate 137 is screwed in the direction towards the central floating body 120, the elastic component can be elongated. When the adjusting nut 136 is screwed towards the center of the central floating body 120, the length of the elastic component 131 can be shortened.

[0069] That is to say, by adjusting the total length of the elastic component, the total length of the connecting beam group 130 can be made variable, so as to reduce the possible gaps during the installation. For example, when the elastic component is connected to the central floating body 120, the gap existing between the second connecting plate 137 and the annular barrel wall 123 can be eliminated by screwing the adjusting nut 136 to elongate the elastic component, so that the second connecting plate 137 is in close contact with the annular barrel wall 123.

[0070] On the other hand, by screwing the adjusting nut (not shown) located on the radially inner surface of the annular barrel wall 123, the elastic component can be compressed, so that the assembly of the platform can be easily carried out even in the case of insufficient radial installation space due to the deformation of the tower barrel.

[0071] However, the embodiments of the gap adjusting member are not limited to the adjusting nut provided on the screw 133. A gap adjusting member can also be additionally provided near the elastic component of the connecting beam group 130 or other bolt / screw assemblies can be selected as the gap adjusting member, as long as it can adjust the elongation or compression of the elastic component.

[0072] For example, as another example, the gap adjusting member includes a connecting bolt 135 and an adjusting nut 136. One end of the connecting bolt 135 is connected to the spring 131. The second end of the connecting bolt 135 passes through the annular barrel wall 123 of the central floating body 120 and is connected to the adjusting nut 136. The adjusting nut 136 abuts against the radially inner surface of the annular barrel wall 123.

[0073] By screwing the adjusting nut 136, the elastic component can be elongated, so that the gap caused by the deformation of the tower barrel 20 (for example, the gap between the second connecting plate 137 and the annular barrel wall 123) can be reduced during the installation of the floating platform 100.

[0074] Figure 5 is a plan view showing the view from the H direction in Figure 4 and shows an example of the arrangement of bolts / screws.

[0075] Referring to Figure 5 , the connecting bolt 135 for connecting and fixing the elastic component can be located at the center of the first connecting plate 138 and the first support plate 139. By making the connecting bolt 135 centered, it can be ensured that the elastic component is located on the radial center line of the connecting beam group 130, thereby improving the stability and operation efficiency of the elastic component.

[0076] The screw 133 used as a sliding component can be symmetrically arranged around the connecting bolt 135. For example, it can be symmetrically arranged above and below or left and right of the connecting bolt 135.

[0077] By arranging the screw 133 in such a symmetric manner, it is easier to ensure the stability of the elastic component and avoid instability caused by insufficient bending resistance of the elastic component.

[0078] Referring to Figure 4 and Figure 5 , as an example, four screws 133 can be symmetrically arranged around the connecting bolt 135. Among them, two screws 133 can be located on one side in the horizontal direction of the elastic component (connecting bolt 135), and the other two screws 133 can be located on the other side in the horizontal direction of the elastic component (connecting bolt 135).

[0079] However, the arrangement of the screw 133 is not limited to the examples shown in the above Figure 4 and Figure 5 .

[0080] Figure 6 is a cross-sectional view taken along the A-A of Figure 1 and shows a modified example of the connection structure of the floating platform 100.

[0081] Figure 7 is Figure 6The enlarged view of part K shows a variant example of the arrangement of the screw rod 133 of the sliding assembly.

[0082] Referring to Figure 6 and Figure 7 as another example, the screw rod 133 can also be symmetrically arranged in the vertical direction with respect to the elastic assembly (connecting bolt 135).

[0083] That is, one or a part of the screw rod 133 can be located on one side in the vertical direction of the elastic assembly (connecting bolt 135), and the other or another part of the screw rod 133 can be located on the other side in the vertical direction of the elastic assembly (connecting bolt 135).

[0084] Figure 8 is a side view of the support base 110. Figure 9 is a bottom view of the support base 110.

[0085] Next, examples of the specific structure of the support base 110 according to this embodiment will be described in detail with reference to Figure 8 and Figure 9 .

[0086] The support base 110 according to this embodiment may include a support platform 111 and a reinforcing rib 112 on the lower side of the support platform 111.

[0087] One side of the support platform 111 and the reinforcing rib 112 can be fixedly connected to the inner wall of the tower barrel 20 by welding, for example.

[0088] The support platform 111 can be used to support and fix one end of the connecting beam group 130. A plurality of through holes 113 can be formed on the support platform 111 to be connected to the radial cross beam 132 of the connecting beam group 130 by bolts, for example.

[0089] However, the structure of the support base 110 is not limited to this, as long as it can be connected to the connecting beam group 130. For example, a support connection part can also be formed on the side of the support base 110 opposite to the inner wall of the tower barrel 20, so that it can be connected to the connecting beam group 130 in the radial direction and support the connecting beam group 130.

[0090] Figure 10 is a top view of the central floating body 120. Figure 11 is from Figure 10 side view of the central floating body 120 observed in the F direction of

[0091] Figure 12 is along Figure 10 sectional view of the central floating body 120 taken along B-B of Figure 12 and in order to more clearly describe an example of the connection method of the central floating body, relevant connection components connected to the central floating body are also shown in

[0092] The following will refer to Figures 10 to 12 to describe in detail the specific structure and connection method of the central floating body 120 according to this embodiment.

[0093] Refer to Figure 10 , the central floating body 120 can be generally centrosymmetric in structure, and connection through holes are symmetrically arranged on its outer peripheral surface, so that multiple connection beam groups 130 can be symmetrically arranged relative to the central floating body 120.

[0094] Through such a symmetric design, the floating platform 100 can be made free from the action of additional bending moments, thereby improving the stability and reliability of the floating platform 100.

[0095] Refer to Figure 10 , the central floating body 120 according to this embodiment is generally annular and has a through hole in the center to allow the cable coming from the upper nacelle to pass through.

[0096] Refer to Figure 10 and Figure 12 , the central floating body 120 can be formed by welding metal plates, so as to have a frame structure to avoid the excessive weight of the central floating body 120.

[0097] Although Figure 12 shows that the cross-section of the central floating body 120 is in the form of a rectangle, the embodiment is not limited thereto. As other alternative examples, the central floating body 120 can also be formed into other shapes such as an inverted "T" shape, an inverted "I" shape, etc., as long as connection holes or support holes can be formed on the wall surface of the central floating body to connect with the connection beam group 130.

[0098] Next, a description will be given with reference to Figure 11 and Figure 12 of an example of the arrangement of the connection holes and support holes on the wall surface of the central floating body according to this embodiment.

[0099] Refer to Figure 11 , a plurality of through holes are formed on the wall surface (for example, the annular cylindrical wall 123) of the central floating body 120 for connecting and supporting the connection beam group 130.

[0100] The plurality of through holes may include bolt connection holes 121 and screw rod end support holes 122.

[0101] The bolt connection holes 121 may be located at the center of the corresponding connection surface of the annular cylindrical wall 123 of the central floating body for connecting to the connection bolts 135 of the elastic component.

[0102] The screw rod end support holes 122 may be symmetrically arranged on the corresponding connection surface of the annular cylindrical wall 123 for slidably supporting the sliding end 141 of the screw rod 133.

[0103] However, the embodiments are not limited thereto. As described above, the installation direction of the screw 133 can also be adjusted, with the fixed end 142 of the screw 133 connected to the central floating body 120 while the sliding end 141 of the screw 133 is coupled to the radial cross beam 132.

[0104] The following will refer to Figures 1 to 12 the exemplary configurations shown to describe the installation method of the floating platform according to an embodiment of the present invention.

[0105] The installation method of the floating platform according to the present embodiment includes: assembling the first set of connecting beam groups 130 (for example, three connecting beam groups 130 adjacent to each other) and the central floating body 120 to the support base 110; rotating the tower barrel and assembling the other connecting beam groups 130. During the process of assembling the connecting beam groups 130, the tension and compression states of the elastic components of the connecting beam groups 130 can be adjusted by using the gap adjusting member so as to easily achieve the assembly of each connecting beam group 130 by adjusting the gap.

[0106] The step of assembling each connecting beam group 130 includes: connecting one end of the radial cross beam 132 of the connecting beam group 130 to one end of the elastic component and the sliding component; connecting the other end of the radial cross beam 132 to the support base 110; connecting the other ends of the elastic component and the sliding component to the central floating body 120.

[0107] However, the step of assembling each connecting beam group 130 is not limited to the installation sequence described above, and the above installation sequence can also be adjusted according to the actual adaptability.

[0108] After the assembly of each connecting beam group 130 is completed, the gap adjusting member is released so that each connecting beam group 130 can adapt to the deformation of the tower barrel by the elastic force provided by the elastic component.

[0109] In addition, according to an embodiment of the present invention, after the assembly of the connecting beam groups 130 of the floating platform is completed, the platform panel can be directly laid on the connecting beam groups 130. Therefore, the installation difficulty problem existing in the prior art of fixedly connecting the platform panel to the inner wall of the tower barrel 20 and the problems of tearing or excessive stress caused by the subsequent deformation of the tower barrel 20 can be avoided.

[0110] Although the above installation method is provided as an example in the above description, the floating platform 100 and its installation method of the present embodiment are not limited thereto.

[0111] Although the case where the sliding component includes the screw 133 is described as an example in the above description, the examples of the sliding component are not limited thereto.

[0112] As a variant example of the sliding component, the sliding component can also be implemented to include a sleeve component, a bushing component, etc. The setting manner of the sliding component is not specifically limited as long as it can slide along the telescopic direction of the elastic component and provide bending resistance.

[0113] For example, when using a sleeve component or a bushing component to form the sliding component, the sleeve component or the bushing component can be located on the periphery or inside of the elastic component, as long as it can provide bending resistance to the elastic component and can slide and expand and contract in cooperation with the expansion and contraction of the elastic component.

[0114] Although the case where the elastic component includes a tension and compression spring is described as an example in the above description, the examples of the elastic component are not limited thereto, and the elastic component can also be implemented in other forms as long as it can stretch or compress the overall length of the connecting beam group 130 in its radial direction.

[0115] As a variant example, the elastic component can also be implemented to include a combination of elastic rubber (or compression spring) and tensile elasticity. In this case, the elastic rubber can provide compressive force in the radial direction, and the tensile spring can eliminate the installation gap in the radial direction during the installation of the floating platform, and provide tensile resistance in the radial direction after the floating platform is installed.

[0116] As an example, the elastic rubber and the tensile elasticity can be arranged adjacent to each other within the same section range of the connecting beam group 130.

[0117] For example, the elastic rubber can be formed into a ring and arranged around the shaft in the bushing assembly. At the same time, one end of the sleeve in the bushing assembly can contact the axial end surface of the elastic rubber. When the connecting beam group 130 is extruded in the radial direction, one end of the sleeve can extrude the axial end surface of the elastic rubber, and provide radial buffering force through the elastic force of the elastic rubber. In addition, when installing the floating platform 100, the problem of insufficient radial installation space caused by the deformation of the tower barrel can also be adapted by extruding the elastic rubber.

[0118] The tensile elasticity can be arranged around the elastic rubber to provide radial buffering force through the elastic force of the tensile spring when the connecting beam group 130 is subjected to tensile force in the radial direction. At the same time, when installing the floating platform 100, the installation gap can also be eliminated by stretching the tensile spring, and the installation difficulty problem caused by the installation gap caused by the deformation of the tower barrel 20 can be reduced.

[0119] In summary, according to the floating platform of the present invention, the installation of the platform can be conveniently and efficiently realized.

[0120] According to the floating platform of the present invention, by applying the elastic component, the installation gap can be eliminated during the installation of the floating platform, and after the floating platform is installed, the impact of external deformation force on the platform can be absorbed, and problems such as platform tearing or excessive local stress can be avoided.

[0121] According to the floating platform of the present invention, by applying the sliding component, the bending load-bearing capacity of the platform can be improved. In addition, according to the floating platform of the present invention, through the cooperative operation of the sliding component, the gap adjusting member and the elastic component, the installation connection of each cross beam can be easily realized.

[0122] Therefore, according to the floating platform of the present invention, the adaptive adjustment ability of the platform can be significantly improved, and the installation efficiency and reliability of the platform can be improved.

[0123] The specific embodiments of the present invention have been described in detail above. Although some embodiments have been shown and described, those skilled in the art should understand that these embodiments can be modified and perfected without departing from the principles and spirit of the present invention defined by the claims and their equivalents, and these modifications and improvements should also be within the protection scope of the present invention.
