Definitions
- the present invention describes a system for supporting the facets to the frame of a heliostat, of those used in thermoelectric solar plants.
- a heliostat consists of a reflective surface like a mirror, whose main mission is to reflect the solar radiation and direct it to the desired place. Said heliostats are steerable and for this purpose it usually has two drives to carry out an individual tracking of the sun on two axes. These drives allow the heliostat to perform azimuth and elevation movements.
- the heliostat therefore, is an element that consists of a reflective surface, a supporting structure, an azimuth and elevation drive mechanism, a pedestal, with its corresponding foundation and a local control system.
- the reflective surface is formed by a set of mirrors, which are on a frame. Each mirror unit together with its frame unit is called a facet. The set of all these facets is the one that will later be mounted on the mobile structure of the heliostat (trusses, arms and drive).
- these reflecting mirrors are slightly curved, the radius of curvature being one of the critical optical characteristics in the manufacture thereof, since to direct the sunlight correctly to the receiver requires a high precision.
- the mirrors Depending on the distance to which the receiver is placed, the mirrors have a certain curvature. To achieve the highest possible performance, it is necessary to respect the curvature parameters of the mirror surface as exactly as possible.
- faceted heliostats we can find in the state of the art, different configurations for the placement of these facets.
- the patent US4276872A discloses by means of its figures a faceted heliostat, where the facets that compose said heliostats, have a structure or support with a flat reflecting surface. These facets are attached to the support of the heliostat. Also in the patent ES8306688 the facets are attached to the structure bonded or embedded in foam.
- the patent ES2326586 describes a facet for heliostat, configured from a flat structure, in which the reflective body is curved.
- the support described for the facet consists of a frame with a series of support points for it.
- through holes can be provided for the connection of the facet with the support of the heliostat, being able to practice around each of the holes a safety of embossments, which stiffen the area surrounding the holes for a better transmission of the efforts from the holes towards the rest of the zones.
- any system or invention that manages to simplify the assembly and manufacture of these mirrors, as well as increasing their strength and reliability, represents a very important advance for this type of technology.
- the present invention aims to develop a facet support that allows to regulate the orientation of the facet inside the heliostat in a way that simplifies the assembly of the mirrors and their replacement in case of breakage of any of them.
- the present invention consists in a support for fastening the facets to the structure of a heliostat.
- the claimed support does not use any type of frame for the facet that is glued or welded to the heliostat. But the support that the invention describes has the property, compared to what has been disclosed up to now, of being a support that allows movement and orientation of the facet within the heliostat assembly, without having to have the mirror mounted.
- the claimed support comprises a connector sheet folded in an "S" shape and a threaded pin.
- the connecting plate holds the facet to the threaded bolt.
- the threaded pin holds the connecting plate together with the structure of the heliostat.
- the connecting plate has in each of its two horizontal surfaces, where it connects with the bolt and the facet, with at least one drill.
- the connecting plate is rigidly joined to the facet by its upper horizontal surface, by means of a screw with washer or equivalent joining system that passes through the connecting plate through its hole.
- the lower horizontal surface of the connecting plate is joined to the threaded bolt (introduced by the hole in the sheet metal), by means of the use of a nut, a spherical and a conical washer, for each of its ends. In this way it is possible to adjust the height of the bolt to which the sheet is fixed and, consequently, the orientation of the facet.
- the bolt at its lower end joins the structure of the heliostat.
- This support or fixing system allows to regulate the orientation of the facet by regulating the height at which the connector plate is placed, so that it can be adjusted without having to have the facet fixed, which greatly simplifies the process of both the original assembly, as of the replacement of mirrors for maintenance, since replacing a mirror does not imply having to orient all facets again as it happens nowadays.
- This system is valid for the use of facets with flat or curved reflective surfaces, but it supposes an extraordinary saving in the cost of the heliostat if it is configured with flat facets, since we would not have the need to bend all the mirrors that constitute the surface of the concentrator, maintaining said concentration capacity thanks to the orientation of the mirrors in the desired shape, either paraboloid or even spherical, for the best concentration of solar radiation.
- the facets of flat reflective surface do not have the effect of astigmatic aberration with which facets have a spherical surface, and its small size can be maintained, which gives it greater advantages, since we can include as many facets as we wish, to shape the heliostat and guide them with this support with great ease and low cost.
- FIG 1 the whole of the invention is observed.
- the support holds the facet (10) together with the structure of the heliostat (20).
- the claimed support comprises, as essential elements, a connecting plate (8) and a threaded pin (4), as well as a fixed connection of the connecting plate (8) to the facet and a mobile connection between the connecting plate (8) and the threaded pin (4).
- the connecting plate (8) is a folded sheet in the shape of "S" that counts on each of its two horizontal surfaces, top and bottom, with a drill (81, 82).
- the holes have different diameters due to the different dimensions of the bolt (4) and the screw (6).
- the connecting plate (8) holds the facet (10) attached to the threaded bolt (4).
- connection between the connecting plate (8) and the facet (10) is shown in detail in figure 4. It shows how the connecting plate (8) is rigidly joined to the facet (10) by its horizontal surface top, by means of a hexagonal head screw (6) with washer (7) that passes through the connecting plate through the hole (81), threatening on the facet (10).
- FIG 3 shows the threaded bolt (4).
- This threaded pin (4) holds the connecting plate (8) together with the structure of the heliostat (20). It is a mobile union.
- the threaded bolt (4) is inserted through the bore (82) of the lower surface of the connector plate (8), holding it to said plate (8) at both ends, by means of a nut (3) a spherical washer (1) and a conical washer (2).
- the lower part of the threaded bolt (4) is fixed to the structure by means of two nuts (9) and two washers (5).
- this joint is mobile allows to fix the orientation of the facet inside the heliostat without the need to have the mirror mounted, which greatly facilitates the maintenance of the heliostat, since in case of breakage of a mirror it is not necessary to return to regular the orientation, if not directly the damaged mirror is replaced by a new one and the orientation of the facet by means of the mobile union of the bolt (4) to the sheet (8) remains intact and only the screw (7) or the Fixed equivalent joint that is installed between the sheet (8) and the facet (10) to perform the maintenance.
- Figure 5 shows a general view of a preferred embodiment of a flat faceted heliostat, where each of said facets is oriented by the mobile attachment of the claimed support. It is verified how, thanks to this support, the desired curvature in the heliostat can be achieved and its manufacture can be reduced by using flat rather than curved facets.
- a preferred embodiment can also be described, such as that shown in figure 6, in which the heliostat is formed by facets of cylindrical curvature and with this type of support the general curvature sought by the independent and individual orientation of each one of the facets.
- This support is designed especially for its application in the manufacture of facets for heliostats of solar concentrating plants, but its extension to other fields of the industry that require assemblies with similar characteristics is not ruled out.
