The present invention relates to a provision for the foundation of a solar collector installed at outdoors, which is connected through a stand with a ground foundation, comprising a container with ballast arranged inside.

State of the art

Flat components are often used, as photovoltaic modules or solar modules and / or heat exchangers, on sloped roofs, which point at Southbound, to take optimal advantage of the radiation solar. However, in part, solar modules should be used to obtaining energy, especially in large areas in uninhabited regions In these cases, there are no surfaces of sloping roofs, on which the components.

In this case, they are needed, so to speak, supports, that is, frame constructions, on which fix the components, so that they are ideally placed in the optimal angle in relation to the sun. Calls are also known tracking units, in which solar collectors follow from  individually or in groups the position of the sun that varies in the course of the day In this case, the solar collectors are moored individually or in smaller groups on vertical columns, which can be tied back in the ground.

Such columns, as well as the racks of support frame constructions are moored in the ground the most of the time by foundation of piles or foundations screwed, to secure the surfaces of solar collectors against storm and other atmospheric influences and against slip or tilt.

However, frequently, such anchors to the soil can only be done with a higher expense, for example in the case of rocky or rocky subsoil, but also in the case subsoil very soft or irregular or variable.

Description

A priority object of the invention consists of in mooring the solar collectors installed outdoors of the as simple as possible and with the most favorable cost possible in soil. At the same time, the anchor must offer stability as safe as possible also in weather conditions unfavorable

This object of the invention is achieved in a arrangement, which consists of at least one solar collector installed outdoors, which is connected through a bracket with a ground foundation, comprising a container with ballast arranged inside, because a high laste is used most favorable cost density. How do you use it? essentially bulk material, material that moves slowly and / or fluid material. As ballast are especially suitable gravel, ballast and / or quarry stones. However, the ballast can be formed in an optional or additional way also by sand and / or other material that moves slowly from comparable density. Such ballast is available in quantities Unlimited and very favorable cost.

According to a preferred configuration of the invention, the container is formed by a rack basket. From In a preferred manner, the grid basket has walls formed by corrosion-resistant wire mesh surfaces. Corrosion resistance can be guaranteed through the use of stainless material. In a preferred way, it use galvanized wire, since this material is cost effective especially favorable. Since the foundation containers are install normally without additional soil preparation, directly on the surface of the earth, it can be advantageous an additional separation layer, which prevents the grilles from container wire are exposed to permanent moisture from the soil or liquids. This separation layer may be formed, for example, for a lot of gravel or ballast at a height of approximately 5 to 10 cm or more.

In addition, it can be provided that at least some of the wire grid surfaces can be separated one of the other and / or can be rotated with respect to the others. The sides of the container, for example, can be suspended or bring down. Optionally, one, two, three or more may be provided. folding sides. The rack can present especially a geometric shape of a parallelepiped, of a polygonal body or of a cylinder, since these shapes can be configured easily by means of several grid surfaces.

Preferably, the rack basket is open on its upper side, so that you can fill the pile of ballast from above. In addition, the rack can be folded flat and can be transported.

At least one side wall, preferably All side walls can be optionally deformable and / or they may be bulging out. Such configuration deals that lateral pressure forces, which occur through from stacking, they can be absorbed better.

In another embodiment of the invention, the side walls and the floor are provided with a thin or closed mesh lining. Such configuration is especially suitable for housing fine grain ballast, which is It moves slowly like sand or similar. The ballast may be formed, in this embodiment variant, also by cement or concrete, which is set after pouring into the container.

The support can comprise at least one column vertical or inclined, which is projected in the center or out of the center from the ground floor. Least one column of the support can also have a lower front side than the minus a horizontal or inclined reinforcement at an acute angle with respect to the horizontal. In accordance with an advantageous configuration of the invention, at least one reinforcement may be arranged below from the bottom of the container. Optionally, on the front side bottom of the column can be arranged two reinforcements horizontal, arranged in a V-shape, that extend along from the bottom side of the bottom of the container. Reinforcements present in a preferred manner a length such that they extend greatly measured on the ground surface. In the case of a column vertical, arranged approximately in the center, reinforcements They can also be cross-shaped.

At least one booster can be connected, of an advantageous way, through a connection, that passes through of the grid surface of the bottom of the container, with the side lower front of the column. This connection, which passes through The grid surface of the bottom of the container, can be especially a screwed connection. In this variant, you can assemble the container quickly and easily from its individual pieces and can be assembled together with the column in the location, before it is completed below with the pile or ballast filling.

The support column can be part of a support frame, comprising several columns, respectively, with a soil foundation for fields of several solar collectors arranged on a regular basis, preferably inclined. Optionally, the support column can be part of a unit tracking, rotating around a vertical axis, with at least a solar collector arranged preferably inclined.

Below are explained again some special aspects and / or configurations of the invention. Since there are very different forms of soil and degrees of difficulty to the introduction of conventional soil foundations, this invention will provide a kind of foundation that remembers in certain mode, the so-called stone tubes or grid containers of wire for flowers and plants in pots. The special novelty of the This invention consists, among other things, in that grid containers consist of a bottom rack geometric shape, adapted to the surface of the foundation needed and can present three, four or more folding cans, which are formed in the same way by metallic fabrics. The sides placed at an angle of approximately 60 ° to 120 ° with respect to the bottom grid they provide a geometric cube body, which It forms the foundation.

In the center or out of the center in this body geometric shaped parallelepiped or cube, a tube cap with a housing for solar uprights, which is connected in positive connection with the grid. The cap of housing or the mandrel of accommodation is tied securely on the bottom surface of the grid container. The bottom of grid and grid sides are coated on the surface against corrosion The container itself has little weight and It can be installed relatively easily and can be placed  in geometric series at a distance to serve as a foundation for a solar amount It can also serve as a foundation for a system solar tracking of one or more uprights. To obtain sufficient resistances in these foundations are filled, according to the needs, in rack baskets, for example, ballast and Coarse-grained quarry stones, whose granules are larger than wire mesh meshes and that prevent them in this way Slip out of the container.

The great advantage of such "foundations of ballast grid container "is the flexibility in the installation and that do not require machines to tamp or screw other foundations In addition, this does not cause any modification ground. On the motherboard, on concrete surfaces or old asphalt surfaces and also in damp places You can install these foundations without having to prepare previously surfaces in a special way. Only to through the amount of padding and the weight that results from this way, tensile forces, pressure forces and bending moments, which act on the foundation and retain with security the solar upright / solar tracking unit on the ground.

The arrangement according to the invention serves for the foundation of solar uprights and / or systems solar tracking and enables the absorption of tensile forces and / or bending moments, conditioned by the combined wind with snow or other environmental influences. The foundations they can be specially made of wire walls grid welded protected against corrosion or fabric braided metal, which are arranged articulated between yes and they set up a geometric shape of a parallelepiped, a triangle or a polygon, which are suitable for housing coarse-grained stones

The foundations may be provided with housing brackets inserted in the center or outside the center, which are suitable for a solar upright or for an installation of follow-up, which must be retained or must be followed in a manner optimal sun.

The foundations provide a figure that is rigidly made or that can be folded, resulting in reduced transport costs from the place of manufacture to the place of installation or
mounting.

A variant embodiment of the figure may have correspondingly formed side walls, which are able to absorb lateral pressure forces of the filling material in a durable way without deformation destructive

Although in the present context there is talk of a predominant manner of a provision, which is constituted by the minus a solar collector and a soil foundation that supports it and stabilizes, it should be stressed, however, that the invention is It also refers to the foundation of the soil itself. This one serves especially for the support and stabilization of the so-called outdoor mounted collectors, but also It can serve other purposes, which are known by the technical.

The characteristics of other developments advantageous of the invention are deduced from the dependent claims as well as from the description following of preferred embodiments.

A possible configuration of an arrangement of according to the invention of at least one, if necessary, several solar collectors are illustrated with the help of figures 2 to 8. In change, the schematic perspective representation of figure 1 shows a support frame 10 known per se for the arrangement  inclined of several solar collectors (not shown) or in form of known photovoltaic elements, which can be used to the conversion of solar radiation energy into electrical energy and, therefore, for the generation of current from light solar. The support frame 10 is tied, so to speak, with several floor clamps 12 on the ground, so that it can ensure a secure fixation of the support frame 10 so as of the solar collectors mounted on top of it. He anchoring of the support frame on the ground by means of floor clamps 12 or by other suitable measures as, for example, piles or the like implies, however, a relatively high expense and therefore not desirable in certain circumstances

In accordance with the present invention, they suppress the floor clamps according to figure 1 and replace by other soil foundations 14, which are formed in each case by a container 16 with ballast 18 arranged therein. How ballast 18 essentially bulk material is used, material that It moves slowly and / or fluid material. The representation of the Figure 2 shows a part of a support frame 12, whose two vertical columns 20 flow into a container 16 in each case. The containers 16 configured in the form of a parallelepiped are still empty The side view of Figure 3 illustrates the arrangement of support frame 12 with containers 16 installed directly on the ground. In the example of embodiment shown, the ballast 18 may be formed by ballast thickness 22, which is indicated by figures 6 and 7.

As illustrated with the help of figures 4 and 5, the container 16 is formed by a rack 26. Of a preferred way, the rack 26 presents, respectively, walls 28 constituted by wire grid surfaces corrosion resistant. Optionally the rack 26 it can be formed by walls 28 fixedly connected to each other. However, it may also be provided that at least some of the wire grid surfaces 28 can be separated from others and / or can be turned relative to each other. The sides 28 of container 16, for example, can be suspended or collapsed. Optionally, one, no, three or more sides may be provided 28 folding. The rack 26 presents, in the example of embodiment shown, the geometric shape of a parallelepiped; This form can be easily configured by means of several 28 grid surfaces flat. The rack 26 is open on its upper side, so that the ballast 22 that forms Ballast 18 can be filled from above. If necessary, the basket of grid 26 can be glued flat and transported.

Optionally, the ballast 18 may be formed also by concrete 24 or cement, which is indicated in figure 8. In this variant embodiment of the invention, the walls sides 28 and bottom 30 of rack 26 are provided in a preferred manner with a thin or closed mesh lining (not shown).

The support of the support frame 10 comprises, for each foundation element 14, a vertical column 20, which is projects out of the center from the ground foundation 14. The column 20 of the support presents on a lower front side 32 two horizontal reinforcements 34, arranged in a V-shape, which are extend along the bottom side of bottom 30 of the container (see figure 5). The reinforcements 34 are arranged below the bottom 30 of container 16 and in each case have a length, which extends largely on the bottom surface 30.

The reinforcements 34 are connected by means of a screwed connection 36, which passes through the surface of bottom rack 30 of container, with lower front side 32 of column 20. In this way the container can be assembled 16 quickly and easily from its parts individual and can be mounted together with column 20 of the frame support 10 at the site, before it is completed then with the ballast heap 18 constituted by ballast 22

As illustrated with the help of Figure 5, the reinforcements 34 may be formed especially by braces of profiled steel, for example with a U-profile. Such profiling makes that the braces 34 are very resistant to bending when they have a sufficient thickness of material, so that they lend a high stability to the entire construction. Since, in addition, they are loaded with the ballast heap 18, the column 20 motionless. In a preferred way, the braces 34 are similarly resistant to corrosion, for example They are galvanized.

The column 20 of the support can be part of a support frame, comprising several columns 20, respectively, with a soil foundation 14 for several fields solar collectors arranged on a regular basis, preferably inclined Optionally, however, column 20 of the support It can also be part of a tracking unit, rotating around a vertical axis, with at least one solar collector (no represented) preferably inclined.

The invention is not limited to the examples of previous realization. Instead, a plurality are conceivable of variants and modifications, which use the idea of the invention and, therefore, enter the same way within the field of protection.
