Description

Technical Field

[0001] This invention belongs to the technical field of solar thermal power generation devices, and particularly relates to a tetrahedral solar collector support component and its assembly, as well as a solar thermal power generation device. Background Technology

[0002] Concentrated solar power (CSP) technology primarily uses mirrors to reflect and concentrate sunlight onto a single point or line, raising the temperature of the working fluid within a collector located at that point or line to generate electricity. The collectors are typically housed in parabolic troughs to capture more heat. The corresponding trough-type collector support serves to support the mirrors and transmit torque, and is a crucial optical instrument for ensuring the efficiency of CSP collection. Therefore, the support structure is extremely important for improving and guaranteeing the collector's heat collection efficiency.

[0003] The collectors used in parabolic trough solar thermal power plants primarily employ torque frame or torque tube structures as their support structures. These structures are characterized by their centralized nature; while they comprise less than 30% of the total collector volume, they account for over 60% of the overall weight. As the chord length of the mirror opening increases, the load increases quadratically, and the corresponding support weight also increases at least quadratically, making large-opening structures highly unsuitable.

[0004] For example, see the torque tube structure disclosed in patent application CN201821092626.X. Figure 1 As shown, the torque tube 8 is the core component of the entire structure, which is typically suitable for collector systems with small trough openings. Because the forces of the entire structure are transmitted to the torque tube 8 through the support wing 6 and the crossbeam 7, the torque tube 8 bears the main combined bending and torsional deformation. If the torque tube structure is used in a large-opening trough collector system, the size of the matching torque tube 8 will also increase accordingly. As a large single component, a completely solid tube is too heavy, and such large-diameter, thick-walled rods can only be rolled and welded, making processing difficult, resulting in large finished product dimensions and significant transportation inconvenience.

[0005] For large-slot solar collector systems, a torque frame structure is generally used, as disclosed in patent application ES201001347. Figure 2 and Figure 3As shown, this is a type of solar collector support structure made of spliced ​​profiles. It lacks large individual structural members, facilitating transportation. However, based on mechanical performance analysis, the upper frame structure, due to its perpendicular sides, has good bending strength but poor torque transmission capacity. The main load-bearing capacity of the torque frame is concentrated on the multiple main beams 3 of the frame, reaching a maximum of 48kN. However, the actual load-bearing capacity of the internal structure and support wings of the torque frame is relatively low, within 5kN. This reflects the irrationality of the torque frame structure; too many structurally necessary members result in low actual load-bearing capacity, leading to a large number of useless redundant members, excessive material usage, and ultimately, a high steel consumption. From a structural perspective, the main frame of the torque frame is rectangular, with each section perpendicular to the others, providing good bending resistance but poor torsional resistance. For novel trough-type concentrating solar collector systems with large openings and long spans, the increase in torque far outweighs the increase in bending moment; therefore, the torque frame structure is not suitable for future development directions. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the purpose of the invention is to provide a tetrahedral solar collector support component and its components and a solar thermal power generation device, which reduces the amount of steel used in the support frame and the material cost while meeting the requirements for the support strength of the collector.

[0007] In a first aspect, the present invention provides a tetrahedral solar collector support member, comprising:

[0008] The load-bearing frame comprises a tetrahedron consisting of six rods; multiple load-bearing frames are provided and connected in sequence.

[0009] A support wing is disposed on the outside of all the load-bearing frames; the support wing includes a support rod, one end of which is connected to the load-bearing frame and the other end extends in the support direction.

[0010] Furthermore, the load-bearing frame includes a first load-bearing frame and a second load-bearing frame, with one side of the first load-bearing frame and the second load-bearing frame on the same plane and connected at an angle; a first crossbeam is provided between the first load-bearing frame and the second load-bearing frame, with both ends of the first crossbeam connected to the corners of the first load-bearing frame and the second load-bearing frame respectively, forming a first structural unit.

[0011] Furthermore, in the first structural unit, the first load-bearing frame and the second load-bearing frame are symmetrically arranged, and the first crossbeam has three parallel crossbeams.

[0012] Furthermore, the load-bearing frame includes a third load-bearing frame and a fourth load-bearing frame, which are connected by a rod to form a second structural unit.

[0013] Furthermore, one side of the third load-bearing frame and the fourth load-bearing frame are on the same plane; a second crossbeam is provided between the third load-bearing frame and the fourth load-bearing frame, and the two ends of the second crossbeam are respectively connected to the top corners of the third load-bearing frame and the fourth load-bearing frame, forming a third structural unit.

[0014] Furthermore, the load-bearing frame includes a fifth load-bearing frame and a sixth load-bearing frame, which are connected on one side to form a fourth structural unit.

[0015] In a second aspect, the present invention provides a tetrahedral solar collector support assembly, comprising the tetrahedral solar collector support member as described above, wherein the tetrahedral solar collector support assembly is composed of at least two combinations of the first structural unit, the second structural unit, the third structural unit, and the fourth structural unit, and the load-bearing frame is arranged in sequence; the support wings are disposed on both sides of the arranged load-bearing frame.

[0016] Furthermore, one end of the support rod is connected to the load-bearing frame, and the other end extends in the support direction and is higher than the load-bearing frame.

[0017] Furthermore, the support rod includes an upper chord and a lower chord, with the high end of the upper chord connected to the high end of the lower chord. The support wing also includes an inner web member, which is connected between the upper chord and the lower chord.

[0018] A third aspect of the present invention provides a solar thermal power generation device, comprising a tetrahedral solar collector support assembly as described above, or a tetrahedral solar collector support assembly as described above; the solar thermal power generation device further comprises a mirrored grid structure, a mirror, and a collector tube sequentially disposed above the tetrahedral solar collector support assembly.

[0019] The beneficial effects of this invention are as follows:

[0020] The main structure supporting the solar collector is a combination of a tetrahedral load-bearing frame and supporting wings. The load-bearing frame and supporting wings form a V-shaped planar truss structure to accommodate the parabolic mirror installation of the solar collector. In addition, the crossbeams connecting the load-bearing frames prevent torque transmission from the load-bearing frame support, thus enhancing the stability of the entire structure.

[0021] The entire support assembly is constructed from rods to form a tetrahedral structure, which ensures uniform and stable stress distribution, excellent spatial stress characteristics, and superior bending moment and torque bearing capacity. This significantly reduces the weight of the support structure and saves on raw materials and production costs. Attached Figure Description

[0048] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings.

[0049] This invention proposes a tetrahedral solar collector support assembly and a solar thermal power generation device, which solves the problem of excessive weight of existing collector supports, resulting in resource waste; this invention reduces the amount of steel used in its support frame and the material cost.

[0050] The present invention proposes a tetrahedral solar collector support component, comprising:

[0051] The load-bearing frame comprises a tetrahedron consisting of six rods; multiple load-bearing frames are provided and connected in sequence.

[0052] A support wing is disposed on the outside of all the load-bearing frames; the support wing includes a support rod, one end of which is connected to the load-bearing frame and the other end extends in the support direction.

[0053] See Figure 4 As shown, the load-bearing frame has a tetrahedral structure with six edges, which is formed by six rods of equal length: rod 101, rod 102, rod 103, rod 104, rod 105 and rod 106. Taking advantage of the fact that the tetrahedral structure has the characteristic of uniform stress on each rod and internal stability, it is very suitable for the construction of structures with spatial stress conditions where forces are borne by all directions.

[0054] Support wings are installed on the outside of the load-bearing frame. The support wings are specifically designed as support rods, with one end connected to the load-bearing frame and the other end extending in the support direction. The combination of the load-bearing frame and the support wings provides support for the solar collector. Specifically, the solar collector is placed above the load-bearing frame and the support wings. The load-bearing frame plays the main role in bearing the load, while the support wings ensure the stability of the solar collector above.

[0055] The aforementioned members are connected by welding, forming a unified structure from the six tetrahedral members. Support rods are then welded onto the tetrahedral members to complete the overall support assembly.

[0056] All of the above-mentioned rods can be set as round rods or square rods; round rods are preferred.

[0057] The load-bearing frame mainly serves a supporting function. When multiple load-bearing frames are set up side by side, such as... Figure 5 and Figure 7 As shown, to improve structural stability, a first crossbeam 501 can be connected between all load-bearing frames. Support wings are also provided on both sides of the load-bearing frames, such as... Figures 9 to 13 As shown, the support wing adopts a support rod structure. One end of the support rod can be connected to the top corner of the load-bearing frame or to a member of the load-bearing frame, thus forming the entire support structure, which can support the trough-type solar collector.

[0058] The load-bearing frame and the support wings on both sides can form a V-shaped structure, which is more conducive to the assembly stability of the solar collector.

[0059] Furthermore, the load-bearing frame includes a first load-bearing frame 201 and a second load-bearing frame 202. One side of the first load-bearing frame 201 and the second load-bearing frame 202 are on the same plane and are connected at an angle. A first crossbeam 501 is provided between the first load-bearing frame 201 and the second load-bearing frame 202. The two ends of the first crossbeam 501 are respectively connected to the corners of the first load-bearing frame 201 and the second load-bearing frame 202, forming a first structural unit 1.

[0060] The combined structure of the load-bearing frame includes the first structural unit 1, such as... Figure 5 As shown, the adjacent first load-bearing frame 201 and second load-bearing frame 202 have one side on the same plane and are connected at one corner; a first crossbeam 501 is provided between the first load-bearing frame 201 and the second load-bearing frame 202, connecting the corner of the two load-bearing frames.

[0061] Furthermore, in the first structural unit 1, the first load-bearing frame 201 and the second load-bearing frame 202 are symmetrically arranged, and the first crossbeam 501 has three parallelly arranged crossbeams.

[0062] More preferably, the first load-bearing frame 201 and the second load-bearing frame 202 are symmetrically arranged, that is, the angles at which they are connected are symmetrical positions. Correspondingly, there are three parallel first crossbeams 501, which are respectively connected to the angles corresponding to the positions of the two load-bearing frames.

[0063] Furthermore, the load-bearing frame includes a third load-bearing frame 301 and a fourth load-bearing frame 302, which are connected by a rod to form a second structural unit 2.

[0064] The combined structure of adjacent load-bearing frames can also be as follows: Figure 6 As shown, the second structural unit 2 includes a third load-bearing frame 301 and a fourth load-bearing frame 302. The two load-bearing frames are connected by a single rod. The two load-bearing frames can be configured such that their sides are not on the same plane, thus allowing for two main axis directions: a first main axis direction and a second main axis direction, serving as the main directions for different supports.

[0065] Furthermore, one side of the third load-bearing frame 301 and the fourth load-bearing frame 302 are on the same plane; a second crossbeam 303 is provided between the third load-bearing frame 301 and the fourth load-bearing frame 302, and the two ends of the second crossbeam 303 are respectively connected to the top corners of the third load-bearing frame 301 and the fourth load-bearing frame 302, forming a third structural unit 3.

[0066] The second structural unit 2 can be further optimized into a third structural unit 3, where one side of the third load-bearing frame 301 and the fourth load-bearing frame 302 are on the same plane; a second crossbeam 303 is provided between the third load-bearing frame 301 and the fourth load-bearing frame 302, with both ends of the second crossbeam 303 connected to the apex corners of the third load-bearing frame 301 and the fourth load-bearing frame 302, respectively. Here, the apex corner refers to the angle relative to the sides on the same plane. For the specific structure, please refer to [reference needed]. Figure 7 As shown.

[0067] Furthermore, the load-bearing frame includes a fifth load-bearing frame 401 and a sixth load-bearing frame 402, which are connected on one side to form a fourth structural unit 4.

[0068] The combined structure of adjacent load-bearing frames can also be as follows: Figure 8 The fourth structural unit 4, the fifth load-bearing frame 401 and the sixth load-bearing frame 402 shown are connected on one side, that is, one side of the tetrahedral frame of the fifth load-bearing frame 401 and the sixth load-bearing frame 402 is the common surface of the two.

[0069] In a second aspect, the present invention provides a tetrahedral solar collector support assembly, comprising the tetrahedral solar collector support member as described above, wherein the tetrahedral solar collector support assembly is composed of at least two combinations of the first structural unit 1, the second structural unit 2, the third structural unit 3, and the fourth structural unit 4, and the load-bearing frames are sequentially connected and arranged; the support wings are disposed on both sides of the arranged load-bearing frames.

[0070] In structures with more load-bearing frames, the first structural unit 1, the second structural unit 2, the third structural unit 3, and the fourth structural unit 4 described above can be combined and connected, as shown in [reference needed]. Figure 12 and Figure 13 As shown, Figure 12 The connection method of the load-bearing frame is the alternating arrangement of the first structural unit 1 and the second structural unit 2; Figure 13 The load-bearing frame is connected by alternating third structural unit 3 and fourth structural unit 4. Alternatively, any two of the above four structural forms can be combined, or three or four can be combined to achieve the load-bearing function.

[0071] Furthermore, one end of the support rod is connected to the load-bearing frame, and the other end extends in the support direction and is higher than the load-bearing frame.

[0072] The support rod extends above the load-bearing frame, forming a V-shaped groove structure with the load-bearing frame. This facilitates the assembly of components such as solar collectors and improves stability.

[0073] The support rod can be a single rod or multiple rods. In a multi-rod structure, it can be a V-shaped diagonal brace or an X-shaped diagonal brace.

[0074] Furthermore, the support rod includes an upper chord 603 and a lower chord, with the high end of the upper chord 603 connected to the high end of the lower chord. The support wing also includes an inner web member, which is connected between the upper chord 603 and the lower chord.

[0075] The support rod is configured to include an upper chord 603 and a lower chord. Both the upper chord 603 and the lower chord are connected at one end to the load-bearing frame and at the other end to each other, forming a V-shaped structure. An inner web member is set in this V-shaped structure to improve the stability of the support wing structure.

[0076] A third aspect of the present invention provides a solar thermal power generation device, comprising a tetrahedral solar collector support assembly as described above, or a tetrahedral solar collector support assembly as described above; the solar thermal power generation device further comprises a mirrored grid structure, a mirror, and a collector tube sequentially disposed above the tetrahedral solar collector support assembly.

[0077] The technical solution of the present invention will be further described in detail below.

[0078] This invention proposes a support structure for a trough solar collector with a tetrahedral spatial truss. The tetrahedral spatial truss is a three-dimensional truss structure composed of interconnected members at nodes, capable of withstanding loads from all directions. By combining the stress characteristics of the trough solar collector with corresponding geometric arrangement design, mechanical balance within the space can be achieved, resulting in advantages such as good stress performance and low steel consumption per unit area.

[0079] This invention relates to a tetrahedral space truss-type trough solar collector mirror support, which mainly comprises two parts: a load-bearing frame structure composed of tetrahedral basic units and a support wing structure connected to the mirror. Each part conforms to the design method of a space truss and is assembled from spliced ​​rods. If necessary, a parabolic mirror grid structure can be added to enhance the compatibility and matching between the frame and different types of mirrors.

[0080] The forms of the rods include, but are not limited to, various types of steel, steel pipes, or steel cables.

[0081] The splicing methods include, but are not limited to, splicing by welding, riveting or bolting with ball joints or irregular joints.

[0082] The tetrahedral structure of this invention is mainly characterized by its extension from tetrahedrals that are regularly repeated along the principal axis (span direction). Typical tetrahedral units include... Figure 4 As shown. All members of the tetrahedron are preferably round tubes, and in principle, there is no difference in function and form among the members.

[0083] Tetrahedral forms include, but are not limited to, the use of regular tetrahedrons. Tetrahedral structures, especially regular tetrahedral structures, have the characteristic of uniform stress distribution among all members and internal stability, making them very suitable for constructing structures in spatial stress conditions where forces are shared from all directions.

[0084] Tetrahedrons are usually connected to each other using different connection methods. Figures 5 to 8 It indicates four connection methods, but is not limited to these four connection methods.

[0085] Figure 5 The diagram illustrates a common-point connection between the first load-bearing frame 201 and the second load-bearing frame 202, forming the first structural unit 1. The two tetrahedral load-bearing frame units share a single node, i.e., one corner of the tetrahedron. Three first crossbeams 501 are provided between the two tetrahedrons to enhance the connection strength between the units. The first crossbeams 501 can be in the form of round or square tubes; there is no difference between the individual first crossbeams 501.

[0086] Figure 6The diagram illustrates a collinear connection between the third load-bearing frame 301 and the fourth load-bearing frame 302, forming the second structural unit 2. The two tetrahedral load-bearing frame units share a single rod. However, the two tetrahedrons are not on the same plane around the shared rod. This structure has two possible repeating main axis directions: a first main axis direction 3011 and a second main axis direction 3021.

[0087] Figure 7 This demonstrates another collinear connection method between the third load-bearing frame 301 and the fourth load-bearing frame 302, forming the third structural unit 3. The two tetrahedral load-bearing frame units share a single member, and two of the shared member's surrounding sides lie on the same plane, increasing the strength between the tetrahedral units. A second crossbeam 303 also exists between the two tetrahedral load-bearing frame units. The second crossbeam 303 and... Figure 5 The description is consistent with the text. Shared members are simply common members and have no special characteristics; no special treatment is required unless otherwise specified.

[0088] Figure 8 The diagram illustrates a coplanar connection between the fifth load-bearing frame 401 and the sixth load-bearing frame 402, forming the fourth structural unit 4. The two tetrahedral load-bearing frame units share a triangular base formed by three members. The shared members are as described previously; unless otherwise specified, no special treatment is required for any of the shared members.

[0089] The four connection methods shown above do not imply that these are the only four connection methods. Tetrahedral elements connected by various connection methods will be used as basic unit cells.

[0090] The main structure constructed by replicating the basic unit requires a supporting structure to support the mirror and transfer the forces acting on the mirror to the main structure. Typically, the supporting structure is located on the sides of the tetrahedron and connects to the mirror or the mirror's space frame. The main supporting structures include... Figure 9 and Figure 10 As shown, this includes, but is not limited to, simple diagonal braces, V-shaped diagonal braces, or support wing structures.

[0091] The following mainly focuses on Figure 7 Taking the third structural unit 3 as an example, it has a common first-level member on the bottom surface with the same plane, and the diagonal bracing structure is connected to the basic unit through nodes. Figure 9 The diagram shown is of a simple diagonal bracing structure. This structure consists of only one diagonal member and is suitable for small loads where the mirror and the connecting basic unit correspond one-to-one. For situations with a large number of mirrors, such as a 1:2 ratio, a V-shaped diagonal bracing method can be used, such as... Figure 10The structure shown employs two support rods: a first support rod 601 and a second support rod 602, forming a V-shaped support to support a row of mirrors. The support rods can be stamped parts or various profiles and round tubes.

[0092] For large-aperture heat collectors that often experience high loads, simple diagonal braces can be replaced with a structure supporting wings, such as... Figure 11 As shown, a support wing is provided on one side of the second structural unit 2. The support wing includes an upper chord 603, which is responsible for bearing the mirror load. Here it is represented as a straight rod, but in reality it may be a curved stamped part or spliced ​​from multiple straight rods connected by bolts, riveting, or welding, depending on the parabolic shape. The support wing may also include a lower chord, which is responsible for transferring the mirror load to the main structure, and two inner web members located between the upper chord 603 and the lower chord: a first inner web member 604 and a second inner web member 605. The inner web members are responsible for enhancing the structural strength of the support wing. In addition, diagonal bracing connecting members can be provided for the support wing, mainly added at the connection between the support wing and the main structure to increase the stability of the support wing structure.

[0093] The supporting wing structure can be entirely stamped as a single piece, partially stamped as a single piece combined with rods, or entirely assembled from rods. The various rods are not significantly different in function and structure, and no special treatment is required unless otherwise specified. When selecting rods, round tubes are preferred, while the upper chord 603 is generally selected as a square tube because it usually has an assembly surface.

[0094] Figure 12 A schematic diagram of a solar collector support structure based on this technical approach is shown. The entire support structure is composed of alternating first structural unit 1 and second structural unit 2. Five support wings are mounted on the main structure of the support. The mirrors are ultimately mounted on the support wings, either directly or through a mirror mesh frame.

[0095] Figure 13 Another support structure constructed according to the present invention is provided. The entire support structure for the solar collector is composed of alternating third structural unit 3 and fourth structural unit 4, with connecting beams used to reinforce the basic units. Multiple support wings are provided on the support body along its extension direction. Each support wing includes an upper chord 603 and a lower chord. Furthermore, to prevent mass unevenness along the main axis span of the main structure, a claw-type connecting brace structure is used to optimize the stress characteristics. The claw-type connecting brace structure includes a first brace 606, a second brace 607, and a third brace 608.

[0096] This section demonstrates two different ways of obtaining space truss supports based on this approach, but it does not mean that the final form can only be achieved through these two methods.

[0097] This structure fully utilizes the advantages of space truss structures, such as good load-bearing performance and light weight per unit square meter. The basic square prism unit has good bending moment bearing characteristics, and the bottom diagonal bracing enhances the torque transmission capacity in the span direction, reducing the mass of the solar collector support by more than 20%.

[0098] Simultaneously, the use of basic unit technology allows for effective modular partitioning and processing of the solar collector, facilitating easier assembly and installation based on functionality, and enabling dimensional expansion in the span direction. This allows for more effective and targeted adjustments to the solar collector according to different environments and design conditions, facilitating personalized design.

[0099] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention. 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 be included within the protection scope of the present invention.
