Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of photo-thermal power generation devices, and particularly relates to a heat collector single-frame support assembly and a photo-thermal power generation device. BACKGROUND

[0002] Photo-thermal power generation technology mainly reflects sunlight to a point or a line through a mirror, so that the temperature of a working medium in a heat collector at the point or the line is increased to generate electricity. The heat collector is usually arranged in a parabolic trough to obtain more heat. A corresponding trough heat collector support plays a role in supporting a mirror and transmitting torque, and is an important optical instrument for ensuring the heat collection efficiency of photo-thermal power generation. In order to improve and ensure the heat collection efficiency of the heat collector, the form of the support is very important.

[0003] The main support form of the heat collector used in a heat collection field of a trough photo-thermal power station is a torque frame or a torque tube structure. The torque frame and the torque tube structure have the characteristic of structural centralization. The torque frame and the torque tube only account for less than 30% of the volume of the entire heat collector, but account for more than 60% of the weight of the entire structure. With the increase of the opening chord length of the mirror, the load will increase in the form of square, and the weight of the corresponding support will also increase in the form of square at least, which is very unsuitable for a large opening structure.

[0004] The torque tube structure disclosed in patent application CN201821092626.X, see Figure 1 The torque tube 8 in the structure is the core component of the entire structure, and this structure is usually suitable for a heat collector system with a small opening. Because the force of the entire structure is transmitted to the torque tube 8 through the support wing 6 and the cross beam 7, the torque tube 8 bears the main bending-torsion combined deformation. If the torque tube structure is used in a large opening trough heat collector system, the size of the torque tube 8 matched therewith will also expand. As a single component with a large mass, the mass of the complete tube is large, and such a large-diameter and large-wall-thickness rod can only be coiled and welded, which has a large processing difficulty. Finally, the single room size of the finished product is large, and transportation is very inconvenient.

[0005] For a large opening trough heat collector system, a torque frame structure is generally used, as disclosed in patent application ES201001347, see Figure 2 and Figure 3As shown, it is a kind of section splicing collector support form, there is no super large single structure rod in the interior, the convenience of transportation is realized. But according to the mechanical property analysis, the square frame structure has good bending strength because the edges are perpendicular to each other, but the torque transmission capacity is poor. The main force of the torque frame is mainly concentrated on the plurality of main beams 3 of the frame body, but in fact the internal structure of the torque frame and the bearing capacity of the support wing are both small. Too many rod structures are used on the torque frame to transmit torque, but the actual force of each rod is low, which increases a large number of useless redundant rods, so the material usage is more, and the steel quantity is more. When the opening size and span of the trough type collector increase, the torque ultimately increases is far greater than the bending moment and the support force. Therefore, for the new type of collector system with large opening and long span, the torsional stiffness is the first factor to be considered, and the square frame structure has defects in structure.

[0042] The exemplary embodiments will be described in detail hereinbelow with reference to the accompanying drawings. In the following description, the same numbers refer to the same elements in different drawings. The embodiments described in the following exemplary embodiments do not represent all the embodiments consistent with the present application. Rather, they are merely examples of methods and systems consistent with some aspects of the present application as detailed in the appended claims.

[0043] The present application provides a heat collector single frame support assembly and a photo-thermal power generation device, which solves the problem of high weight of the existing heat collector support, causing resource waste, and reduces the steel consumption and material cost of the support frame.

[0044] The heat collector single frame support assembly provided by the present application comprises:

[0045] The force bearing frame is mainly composed of a first rod 101, a second rod 102, a third rod 103 and a fourth rod 104, wherein the first rod 101, the second rod 102, the third rod 103 and the fourth rod 104 are all arranged in an inclined manner and are sequentially connected at the head and tail to form the force bearing frame; the force bearing frame comprises two corners in the horizontal direction and two corners in the vertical direction; a plurality of force bearing frames are arranged and are spaced from each other.

[0046] A first cross beam rod 105 is arranged along the arrangement direction of the force bearing frame; two ends of each first cross beam rod 105 are respectively connected to the same ends of two first rods 101, two second rods 102, two third rods 103 or two fourth rods 104 of adjacent force bearing frames.

[0047] The support wing 6 comprises a bearing rod and a support rod, wherein one end of the bearing rod is connected to the top corner of the force bearing frame, and the other end of the bearing rod is arranged to extend to one side of the vertical direction and away from the force bearing frame; the bearing rod is a bent rod, and the other end of the bearing rod is bent upward; one end of the support rod is connected to the horizontal corner of the force bearing frame, and the other end of the support rod is connected to the bearing rod.

[0048] Referring to Figure 4 Fig. 1, in the structure of each force bearing frame, the first rod 101, the second rod 102, the third rod 103 and the fourth rod 104 arranged in an inclined manner are sequentially connected at the head and tail to form a rhombus structure, wherein the four rod structures are made of the same material and are connected in an integral structure by welding, so that the first rod 101 and the third rod 103 are arranged in parallel, and the second rod 102 and the fourth rod 104 are arranged in parallel; each force bearing frame is a rhombus structure comprising two corners in the horizontal direction and two corners in the vertical direction. The middle arch of the rhombus structure can well support the middle position, and the other diagonal line is arranged to be longer to resist the stress in the opening direction of the large opening groove type heat collector. The width of the main structure should account for more than 60% of the width of the mirror surface. The ratio of the long and short diagonals of the rhombus generally depends on the size of the edge angle of the mirror surface, and the ratio is usually between 2:1 and 3:2.

[0049] In the structure of the plurality of force bearing frames arranged side by side, as shown in Figure 4 and Figure 5 a first cross beam rod 105 is arranged between the first force bearing frame 201 and the second force bearing frame 202, and two ends of each first cross beam rod 105 are respectively connected to the same ends of two first rods 101, two second rods 102, two third rods 103 or two fourth rods 104 of adjacent force bearing frames, so as to ensure the structural stability between the adjacent force bearing frames.

[0050] The multiple force bearing frames are arranged side by side along the axial direction of the heat collector, and the gravity center of the heat collector is located at the top corner of the rhombic force bearing frame; in order to strengthen the stability of the heat collector on the force bearing frame, the support wing 6 is arranged on at least one side of the force bearing frame. The support wing 6 adopts a combined structure of a bearing rod and a support rod, the bearing rod is a bent rod bent upward, one end of the bearing rod is connected to the top corner of the force bearing frame, and the other end of the bearing rod extends to one side of the vertical direction and away from the force bearing frame; in this way, an arc-shaped groove is formed to prevent the heat collector from slipping off; one end of the support rod is connected to the horizontal corner of the force bearing frame, and the other end of the support rod is connected to the bearing rod to form a support effect on the bearing rod and the heat collector.

[0051] If the gravity center of the heat collector deviates to one side of the force bearing frame, the support wing 6 must be arranged on the side; if the gravity center of the heat collector is located on the line connecting the top corner and the bottom corner of the force bearing frame, the support wing 6 needs to be arranged on both sides of the force bearing frame.

[0052] Further, the adjacent force bearing frames are further provided with inclined support rods 301, and the inclined support rods 301 are provided in plurality; two ends of each inclined support rod 301 are respectively connected to adjacent force bearing frames, and two ends of each inclined support rod 301 are respectively connected to different ends of two first rods 101, two second rods 102, two third rods 103 or two fourth rods 104 of adjacent force bearing frames.

[0053] The rhombic force bearing frame structure has good support and bending moment resistance ability in the span direction, but the torque transmission ability is poor, therefore, the inclined support rods 301 are arranged between adjacent force bearing frames, as shown in Figure 5 The inclined support rods 301 must form a spiral structure on the adjacent force bearing frame structure to realize the transmission of the torque around the main body structure and the short path.

[0054] The whole force bearing frame is used for bearing the bending moment of the heat collector, and plays a supporting role in bearing the heat collector; each rod member can be made of the same profile material, including a round rod made of a circular tube, or a solid rod.

[0055] The inclined support rods 301 are arranged between the multiple interval arranged force bearing frames, and the inclined support rods 301 can be arranged in X-shaped intersection to resist the torque that may occur when the force bearing frame bears the heat collector, so as to improve the stability between the multiple force bearing frames.

[0056] The multiple force bearing frames are combined with the inclined support rods 301, the force bearing frames are responsible for the supporting effect, the inclined support rods 301 between the force bearing frames play a role in resisting the torque transmission, and constitute a heat collector single frame support assembly. The torque structure of the heat collector single frame support assembly is quite different from the traditional torque structure, and is different from the past torque frame and torque pipe which not only bear the torque but also bear the bending moment force conducted by the support wing 6; the torque structure of the present application is the inclined support rod arranged between the force bearing frames, and is only responsible for the transmission of the torque structure.

[0057] Further, the support frame is provided with the support wing 6 on both sides, and the support rods of the two support wings 6 are arranged in a V shape with the top corner of the support frame as the vertex.

[0058] The support wing 6 is arranged on both sides of the support frame, and the support wings 6 on both sides are arranged in a V shape with the top corner of the support frame as the vertex, thereby forming a large V-shaped groove structure, which can well support the collector. The mirror surface structure 503 between the collector and the V-shaped groove can form an arc, thereby better collecting light.

[0059] Further, the support rod is provided with two ends, and the other end is connected to the bending part of the support rod and the other end.

[0060] In the support wing 6 structure, two support rods, a first support rod 401 and a second support rod 402, are used. One end of the first support rod 401 and the second support rod 402 is connected to the horizontal corner of the support frame, the other end of the first support rod 401 is connected to the bending part of the support rod, and the other end of the second support rod 402 is connected to the other bending end of the support rod, thereby well supporting the support rod. At this time, the two support rods are arranged in an inclined manner, as shown in Figure 6 .

[0061] Further, a plurality of support wings 6 are arranged along the interval arrangement direction of the support frame, and a second cross beam 501 is arranged between adjacent support wings 6. The two ends of the second cross beam 501 are connected to the same part of the adjacent two support rods.

[0062] The second cross beam 501 is arranged between the adjacent support wings 6, so as to enhance the structural stability of the plurality of support wings 6. In combination with the first cross beam 105 between the adjacent support frames, the structural strength and stability of the structural unit formed by the support frame and the support wing 6 and the plurality of structural units are improved.

[0063] Further, a diagonal bracing rod is arranged between the adjacent support wings 6. One end of the diagonal bracing rod is connected to the bottom end of the support rod of one support wing 6, and the other end is connected to the support rod of another support wing 6.

[0064] In order to improve the torsional moment of the support wing 6, a diagonal bracing rod is additionally arranged between the adjacent support wings 6, as shown in the first diagonal bracing rod 405, the second diagonal bracing rod 406, the third diagonal bracing rod 412 and the fourth diagonal bracing rod 413 in four different positions. Figure 6

[0065] Further, a plurality of diagonal bracing rods are arranged along the arrangement direction of the plurality of support wings 6, and are sequentially connected.

[0066] ​More preferably, the plurality of inclined struts are connected in sequence along the arrangement direction of the support wing 6, so that the torque can be transmitted and the anti-torque effect can be achieved.

[0067] Further, the single-frame supporting assembly of the collector further comprises a net rack structure 504, which is laid on the force-bearing frame and the support wing 6, and is used for assembling the mirror structure 503 of the collector.

[0068] The net rack structure 504 is arranged on the force-bearing frame and the support wing 6, and the mirror structure 503 of the collector is assembled on the net rack structure 504, so that the net rack structure 504 can disperse the gravity of the entire mirror structure 503 and the collector to the force-bearing frame and the support wing 6.

[0069] The net rack structure 504, referring to Figure 8 As shown in the figure, a typical net rack structure 504 comprises horizontal beams and vertical beams arranged in a cross manner, and the mirror holder, i.e., the mirror support, is arranged on the net rack structure 504 and used for supporting the mirror structure 503. There is no difference in structure between the horizontal beams and the vertical beams, and the horizontal beams and the vertical beams are preferably bars, and the type is square tube, and other flat profiles can also be used.

[0070] The mirror holder has a certain adjustability, and the lens is connected by adhesive connection. The mirror holder is vertically arranged relative to the net rack structure 504, and can be configured as a relatively small short rod.

[0071] The second aspect of the present application provides a photo-thermal power generation device, which comprises the single-frame supporting assembly of the collector as described above, and further comprises a mirror structure 503 mounted on the force-bearing frame and the support wing 6, and the cross section of the mirror structure 503 is arranged in an arc shape.

[0072] Further, the photo-thermal power generation device further comprises a collector, which is arranged in the arc of the mirror structure 503, and the axial direction of the collector is the same as the axial direction of the mirror structure 503.

[0073] The photo-thermal power generation device of the present application divides the stress of the collector into two parts, i.e., bending moment bearing and torque bearing.

[0074] First, in order to ensure the ability of the support mirror of the collector, the corresponding force bearing frame structure is designed, the force bearing frame adopts a diamond structure, the stress is realized by using the top corner, and is dispersed to each inclined rod, then combined with the bearing rod of the support wing 6 and the support rod below the bearing rod, a complete support structure is formed; the upper surface of the entire support structure is designed as a flat truss type structure with a similar V type to adapt to the parabolic mirror surface form; at the same time, the entire support structure itself is preferably an integrated welded truss net. The entire force bearing frame structure of the welded structure has the optimal overall mechanical performance, compared with the common riveting and bolt connection mode, there is no obvious stress concentration and obvious weak stress point. If the overall welding transportation is not suitable due to the actual situation of the project location and the like, the profile or round pipe joint form is also the preferred sequence.

[0075] After the entire support structure is responsible for supporting, the torque transmission structure between the force bearing frame structures, the inclined support rod 301, and the inclined bracing rod between the inclined support structures are arranged, the torque structure here is different from the traditional torque structure, unlike the past torque frame and torque pipe which not only bear the torque but also bear the bending moment force conducted by the support wing 6, the torque structure of the present application is the inclined bracing rod arranged between the force bearing frames and the inclined bracing rod between the inclined support structures, which is only responsible for the transmission of the torque structure. As the torque transmission rod, the round pipe can also be used for splicing. The rod of the torque transmission structure should be connected with the peripheral rod of the force bearing frame structure as much as possible to pursue a larger transmission route rotation radius and improve the torsional stiffness of the structure.

[0076] The force bearing frame and the support wing 6 form the main structure of the collector support, a typical main structure is shown in Figure 6 There is no obvious difference between each main structure. Due to the tooling and end surface structure requirements, the force bearing frame structures at both ends are preferably selected to have profile structures with assembly surfaces when the welded structure is not used. The end face force bearing frame can be independently designed and is composed of a plate or a welded plate. A plurality of groups of inclined support rods 301 structures are arranged between adjacent force bearing frames to form a spiral type torque transmission route with the maximum rotation radius. First cross beam rods 105 are also arranged between adjacent force bearing frames, all the first cross beam rods 105 are responsible for resisting the bending moment stress in the span direction, there is no essential difference in function, only in position. The square tube or other profile structure with assembly surface can be selected if there is a need for assembly, and the round pipe rod is preferred if there is no assembly surface on the rod.

[0077] Referring to Figure 8As shown, the complete version of the heat collector support is shown, and the support wings 6 are arranged on both sides of the load-bearing frame, and the bottom ends of the two support wings 6 are connected with the horizontal angle of the load-bearing frame. The above-mentioned rods are all profiled or circular pipes, and when there is no special description, the circular pipe structure is preferred.

[0078] The heat collector support of the present application is formed by splicing the load-bearing frame structure and the torque transmission structure-support wing 6, which can improve the torsional stiffness by 10% and reduce the weight by 30% compared with the current torque frame structure.

[0079] When the load-bearing frame structure is welded and prefabricated, the entire structure is easy to modularize, and has the advantages of better ensuring the machining precision and installation efficiency. Other non-welded rod members are more uniform in form, easy to process, transport and assemble.

[0080] At the same time, because the stress structure is divided according to the stress structure, the stress analysis and optimization iteration of the entire structure are more targeted, such as insufficient torsion, which can be directly changed for the intercostal torque part, and the load-bearing frame structure has less effect on the torsional stiffness, so the design and development are efficient.

[0081] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of the present application, and not to limit them. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application. Any changes or replacements that can be easily thought of by those skilled in the art within the technical scope disclosed by the present application should be covered within the protection scope of the present application.
