Description

The invention concerns a device for installing solar modules / solar panels using support posts driven in the field, preferably protective fence posts with cross section in E. The device is especially suitable for installing solar modules side by side. in a row and with inclination in south direction.

Supports of solar modules / solar panels using support post are known.

A first group uses a row of support posts that are joined by the side of the head through a beam on which the solar modules are then directly juxtaposed (DE 203 03 257 U1) or using direction-oriented crossbars north-south (document DE 203 19 065 U1).

In the case of the direct arrangement, among others, due to the wider support base, protective fence profiles arranged in an inclined position are used or the beam is formed based on two parallel beams joined together by means of souls , fixing the side of the head in the area of the souls (document DE 20 2006 011 393 U1).

The fixing of the beams or the souls in the support posts is materialized by means of stirrups or angles that offer a possibility of height and lateral direction regulation, so that inaccuracies of position of the pillars of support can be compensated and The beam can be mounted in a horizontal position. The angle of inclination for the optimal incidence of solar radiation is also determined previously by means of the shape of the stirrups or the angles.

Thus, JP 61 04 0063 A describes a device for installing solar modules by means of a support post in which several beams connected to each other are arranged for the solar module. The beams are articulated together with one another and in an adjustable way with the support post, so that the working position of the solar module can be varied. The mounting of the support post on a ground bushing also allows a rotation around the axis of the post.

In this group of supports, the instability under external loads (wind, snow) caused by only one row of support posts is especially disadvantageous. Also, with the prefabricated stirrups or angles, the maneuvering space is restricted with respect to a specific adjustment of the location.

A second group of supports uses double rows of support posts that create a mounting base for the modules / solar panels by means of north-south beams and / or crossbars (documents DE 10 2005 015 346 A1, US 4,966,631).

The fixing of the beams to the support posts is carried out here also using angular ones. As far as the issue of compensation possibilities during assembly is approached, elongated holes are also suitable here for screw connections.

The problem of the invention consists in proposing a form of support for solar modules that offers a high degree of compensation possibilities for deviations as a result of the support posts, and the technical means used for it must be used in a universal way. that is, not specific to the location.

This problem is solved with the characteristics of claim 1; Advantageous executions are subject to the dependent claims.

The device according to the invention for installing solar modules / panels on support posts driven into the floor of the installation site, beatable beams being arranged on or on the support posts with the help of fixing means that allow height compensation and / or lateral compensation of vertical deviations of the pillars, provided as fixing means

- a lane that can be attached to the support post,

-

 a T or L or U shaped connection tab with at least one connector for a beam for solar modules and

-

 an articulation bearing through which the connection rail-flange connection can be established, the articulation bearing between an inner ring and an outer ring having a sliding engagement configured in a spherically curved shape.

Due to the advantageous arrangement of a joint bearing, a possibility of almost universal compensation for deviations from the vertical arrangement of the respective support post is created in a simple and inexpensive way.

In an advantageous embodiment, the rail has a housing for the outer ring of the joint bearing in the upper end area away from the support post, and the inner ring of the joint bearing inserted in the housing can be joined with the connecting flange.

Naturally, the inverted arrangement is also possible, namely that a wing or core of the connecting flange has a housing for the outer ring of the joint bearing and the inner ring of the joint bearing inserted in the housing can be joined with the rail.

Another advantageous embodiment provides that the T-shaped connection flange is configured in the form of a fork with two souls whose free distance is dimensioned so that the souls each grip frontally on the inner ring of the articulation bearing and can be join with the inner ring by means of preferably a bolt joint.

It is understood that the wings or souls of the connection flange applied to the inner ring of the articulation bearing must still have a certain distance from the rail so that the possibility of regulation created with the articulation bearing can also be exploited. In other words, the width of the inner ring of the joint bearing must be greater than the thickness of the rail in this area.

As a joint bearing, bearings are used which have a spherically curved sliding engagement between the inner ring and the outer ring. Since the slip pairing is used in principle only once during assembly, an absolutely poor maintenance bearing and not designed for permanent dynamic load can be used.

Another possibility of compensation is given by the fact that the rail can be joined with the support post in height-adjustable way. An advantageous embodiment provides in this respect that the rail, at least in the area of the fixing with the support post, is configured as a hollow profile and / or as a profile with external longitudinal grooves or souls, so that said rail can plug in and / or into the support post or parts of the support post.

In another embodiment, which is represented in the drawings, it is planned to configure the rail in a divided way, in a partial connecting rail for the support post and a partial rail to establish the connection with the connecting flange, the two being able to join partial lanes with each other.

The support posts are preferably arranged in double row, so that the beams arranged on the connecting tabs run each one in a north-south direction, that is to say that they join two support posts and these beams are joined by continuous crossbars. on which the solar modules are arranged.

The invention will be explained with reference to embodiments. They show:

Figure 1, the various components of the device,

Figure 2, the lane configured in divided form,

Figure 3, the connection tab arrangement and

Figure 4, fixing the connection flange.

Figure 1 shows the essential components of the device for installing solar modules / panels in a representation similar to an exploded view.

At the bottom 1 of the installation site a support post 2, preferably a protective fence post with a cross-section in en, has been driven. The support post 2 joins the beam 5 with the help of fixing means comprising

-

 a lane 3 that can be joined with the support post 2,

-

 a connection flange 4 of T or L or U shape with at least one connector 8 for beam 5 and

- an articulation bearing 6 through which the rail connection 3 - connection flange 4 can be established.

The articulation bearing 6 is arranged in a housing for the outer ring of said articulation bearing, in an upper end area of the rail 3 away from the support post 2. The inner ring of the articulation bearing 6 inserted in the housing can be joined with the connection tab 4.

A preferred embodiment of the device is shown in detail in Figures 2 to 4. The rail 3 with connection flange 4 to tie the beam 5 is configured here as a split rail with a connection rail 3.1 for the support post 2 and a partial rail 3.2 for the connection of the connection tab 4. The partial rail of connection 3.1 for the support post 2 is configured as a hollow profile and / or as a profile with external longitudinal slots or souls 9, so that said rail can be connected to and / or inside the support post 2 or parts of the support post 2.

As can be seen in Figure 3, the partial connection rail 3.1 is configured as a hollow rail with side grooves 9. These are sized so that, by connecting the partial connection rail 3.1 on the de-shaped support post 2, the wings of the Σ of the support post 2 angled inwardly fit into these grooves 9 and thus a lateral coupling of form is formed between the partial connection rail 3.1 and the support post 2. The partial connection rail 3.1 for the support post 2 is screwed with it in a variable height.

The partial rail 3.2 is plugged into a hollow profile of the connecting rail 3.1 and is screwed with it. This can be done in a rigid position fixed by the holes and stops. However, it would also be possible to use the following degrees of freedom: tilt around the union bolt 10 and / or height adjustment using an elongated hole.

The partial rail 3.2 contains the articulation bearing 6, whose inner ring protrudes externally from the partial rail 3.2 and can be joined with the connecting flange 4.

In Figure 4 it can be clearly seen that the connection flange 4 made as a T is configured in the form of a fork with two souls 4.2, 4.3 whose free distance is dimensioned so that the souls 4.2, 4.3 are grabbed frontally each of them on the inner ring of the articulation bearing 6 and can be joined with the inner ring by means of preferably a bolt joint 7.

The connection flange 4 can thus be inclined in all directions with respect to a horizontal plane and, therefore, can compensate for deviations from the vertical arrangement of the support posts 2. Height differences can be compensated by longitudinal displacement of the rail partial connection 3.1 with respect to the support post 2.

Follow the fastening of the beams 5 by means of the connectors 8 in the form of holes of the tester 4.1 of the connection tab 4 in the form of T.

Since the function of the bearing or articulation bearings 6 of the different support posts 2 has not been annulled by the screw connection with the connection tabs 4, an alignment of the connections 8 is also carried out automatically. connecting tabs 4 with the connecting surface of the beam 5. In case of several support posts 2, beams 5 and crossbars, the entire frame is aligned by itself and guarantees a flat and continuous seat base for the solar modules to arrange in a row and next to each other.
