Definitions
- This invention falls within the sector of solar collectors, more specifically it refers to the structures that are used to hold said collectors responsible for concentrating solar radiation.
- solar collectors In solar energy production plants from solar radiation you can use solar collectors of various types (cylindrical collectors, Stirling disc, tower center with heliostats, Fresnel collectors, etc.) and all of them require support structures for mirrors They are responsible for concentrating solar radiation.
- parabolic troughs whose primary reflector is a parabola.
- parametric cylinder a new type of collector
- the latter are distinguished from parabolic trough collectors because the geometry of the primary reflector does not correspond to a parabola.
- the reflector does not correspond to a continuous curve, if not that is sectioned obtaining what is called the discontinuous primary reflector, to achieve additional advantages, since it allows the wind to evacuate and reduce the associated loads per m 2 of mirror.
- a secondary reconcentrator is also added, generally above the receiver, which increases the concentration of solar radiation on the receiver.
- lattice structures that support parabolic trough collectors.
- the structures that support these collectors are formed by a series of beams, arms and joints, being understood by beams those elements that serve as support of the central structure, also called torque box. They are beams subjected to great torsion and bending forces and usually, of a great length, which causes problems due to the arrow that this produces and also greatly complicates their transport to the plant.
- the invention claimed herein is intended to provide a structure of great versatility, to serve as a support for a cylindrical solar collector module, either parabolic or parametric, with the continuous primary reflector or discontinuous, with or without secondary reconcentrator and accepting any receiver geometry.
- the solar tracker that can then be coupled to it is not the subject of the invention.
- the invention has a series of characteristics that make it differ substantially from those known in the state of the art, solving technical problems so important in this type of collectors such as the structural resistance of the assembly, reduction of loads, ease and cheaper transport and assembly.
- the invention consists of a support structure for a cylindrical solar collector module.
- Receiver element responsible for the absorption of solar energy and through which the fluid that is heated circulates. There are several geometries, the most common comprising two concentric tubes, one inside metal through which the fluid circulates and another outside glass, keeping empty between them. The structure proposed by the invention is valid for any receiver geometry.
- Secondary reconcentrator reflective element that increases the concentration of solar radiation on the receiver, but that is not always installed in the collectors. If placed, it is usually placed above the receiver.
- Solar tracker the most common tracker system consists of a device that rotates the reflector around an axis.
- the mission of the structure of the collector is to support and stiffen the set of elements that compose it. This element is the object of the present invention.
- the claimed invention focuses on developing a structure that, unlike the known state of the art, has a number of essential characteristics that give it important advantages over what exists in the sector.
- Geometry of the central body type torque box one of the main features that are incorporated in the torque box is the change of its geometry with respect to the state of the art, since it goes from being rectangular or triangular section, to being cylindrical or multi-face polyhedral. Another of the differences in its geometry is that the torque box is not composed of a single piece, but that it is formed by a series of sectors of equal length and each of the sectors is in turn formed by several thin curved sheets or folded The sheets are transported stacked, greatly facilitating logistics and achieving an ideal transport system.
- each of the sections are mounted starting from the plates and then the complete torque box is assembled, joining the different sectors with parts called diaphragms that materialize the union and prevent local dents from occurring in the cylinder due to the point loads exerted by the pyramidal base supports of the concentric tube receiver.
- the torque box designed in this way is responsible for supporting the torsional stresses caused by the receiver's weight, the proper weight and the wind forces.
- the triangular lattice structures that support the complete primary reflector are supported if it is continuous or any of its sections if it is discontinuous.
- the intermediate pyramidal base supports that support the receiver if it is concentric tubes, as well as the legs that support the whole structure on the ground.
- Hexagonal frames surrounding the torque box along its length, the torque box is embraced by hexagonal frames in successive sections.
- the frames also perform the function of joining triangular lattice structures to the torque box.
- Hexagonal frames are made with "L" angles, all their joints will be resolved with rivets or any equivalent joint system.
- Cable-stayed structure the whole structure is prestressed by two horizontal braces, optimizing its flexural behavior, thus avoiding having the torque box supported only on the legs. This problem could have been solved by increasing the thickness of the tube, which would give greater rigidity, but the price and weight would also have been increased.
- the braces work in opposition to the arrow, this one tries to produce in any of the positions or orientations that the torque box adopts and depending on these positions, one or the other brace or both will work, but they will always work opposing the deformation.
- the straps have some mooring points at the ends thanks to which they are able to give the desired pretension and intermediate points only through which allow them to be given the necessary curvature and manage to maintain tension.
- Lattice pillars responsible for supporting the secondary reconcentrator if it exists and in some cases, also the receiver. These pillars rest on the upper section of the hexagonal frame.
- Pyramid-based brackets they are installed in certain cases to support the receiver directly on the torque box, instead of installing lattice pillars on the hexagons. They rely directly on the torque box taking advantage of its multi-sided circular or polyhedral geometry, not needing any other intermediate element.
- the structure has a triangular lattice structure, similar to those existing in the state of the art, whose mission is to support the complete primary reflector if it is continuous and the sections of the reflector ends, if it is discontinuous.
- This structure is made with "L" angles, with riveted joints or equivalent.
- FIG. 3 Perspective view of the structure of the preferred embodiment
- FIG. 5 Folded plates that make up each section of the torque box
- Torque box cover that connects a module with the adjoining
- the solar collector module will be described in accordance with a preferred embodiment.
- the collector supporting the structure is a cylinder-parametric collector, with discontinuous primary reflector divided into three sections: two parametric at the ends (17) and a higher central parabolic (17 ').
- the receiver is eccentric tubes (2) and will be supported on a lattice pillar (20) supported by the hexagonal frame (19).
- FIG. 1 shows the elevation of a preferred embodiment of the claimed structure.
- the torque box or central body of the structure (1) has a total length of 12 meters.
- the torque box (1) is divided into three sections (3) of 4 m each. To join the sections (3) and form the entire tube (1) pieces called diaphragms (5) are used.
- the triangular lattice structure (16) is supported and the legs that support the whole structure (not shown) are supported.
- two covers (10, 12) are placed.
- one of the covers (12) is located the axis of rotation of the collector (11).
- the other cover (10) is used to connect this solar collector module with its adjoining one.
- FIG. 2 A profile view of the claimed structure is shown in Figure 2.
- the hexagonal frame (19) that embraces the torque box (1).
- the torque box (1) is reinforced in several sections thanks to these hexagonal frames (19).
- the upper side of the hexagon (19) is used to support a lattice pillar (20) that supports the receiver (2).
- the hexagonal frame (19) also supports the central parabolic section (17 ').
- the two sides of the hexagonal frame (19) adjacent to the top are free.
- the three lower sides of the hexagon (19) allow the transition of the torque box (1) to the triangular lattice structures (16).
- the claimed structure in addition to the torque box (1), comprises a triangular lattice structure (16), which consists of an enveloping structure to support the parametric sections (17) of the reflector. It is made with “L” angles, all joints being solved with rivets or equivalent joining methods.
- FIG. 3 An axonometric perspective view of the structure is shown in Figure 3. It represents the horizontal braces (13, 15) that prestress the whole structure. These braces (13, 15) are placed one on each side of the torque box (1). Its mission is to optimize bending behavior and solve the problem of the arrow that appears to have the torque box (1) resting only on the legs. Thus, the braces work opposing the arrow, which is intended to be produced in any of the positions adopted by the torque box (1).
- the straps have some mooring points at the ends thanks to which they are able to give the desired pretension and intermediate points only through which allow them to be given the necessary curvature and manage to maintain tension.
- Figure 4 shows the detail of the connection of the supports (6) of pyramidal base (18) that can support the receiver (2) to the torque box (1), in the case of not installing the lattice pillars (20) .
- the fact that the geometry of the torque box (1) has changed and is a polyhedron (or cylinder) allows the union element between the receiver (2) and the cylinder (1) to be greatly simplified since, As can be seen in Figure 4, the support (6) can be supported on the torque box (1) with a simple pyramidal base (18), while with the triangular or square geometry of the state of the art developments, You need to introduce a much more complex transition element between the two to adapt the geometries, which complicates and makes mounting more expensive.
- FIG. 5 shows the plates (4) that form each of the sections (3) of the torque box (1).
- each section (3) of the torque box (1) is formed by three folded or curved sheets (4) that when assembled, form the polyhedral or cylindrical tube that is the torque box (1). In figure 5 they appear as curved sheets, but they could also be made of folds.
- FIG. 6 shows the detail of the geometry of the diaphragms (5) discussed in Figure 1. Thanks to them it is possible to materialize the union between the different sections (3) that make up the torque box (1), increasing the stiffness of the set and reducing the torsion efforts.
- the diaphragms (5) are joined to the plates (4) that form the sections (3) of the torque box (1) by riveting (7) or any equivalent joining system. They consist of a hexagonal (8) or cylindrical plate (depending on the geometry of the torque box (1)), whose folds or curvature coincides with that of the plates (4) of the sections (3) of the torque box (1). They also comprise a series of spokes (9) that stiffen the assembly. For 12m tubes, divided into three sections of 4 m each, two diaphragms (5) are required.
- the described structure is specially designed for application in cylindrical solar collectors, but its extension to other fields of the industry that require similar characteristics is not ruled out.
