Description

S e i 1 / Kab e 1 me ch a n i s mu s for swiveling at least one table for ph o t o v o 11 a i kmo du 1 e k k k k k k

The present invention relates to a egg 1 / cable 1 mechanism for swiveling at least one table for ph otovo 11 ai kmo du 1 e by at least two further implementations of the egg 1 me ch anis mu sses according to the characterizing part of the claim.

 A large number of K ab e 1 me ch a n i s me n for pivoting Ph o t o v o 11 a i kmo du 1 e n or structures are known from the prior art which support these so-called tables for Ph o t o v o 11 a i kmo du 1 e. A table can be carried by several supports. The purpose of these mechanisms is to use the photo 11 a i kmo du 1 s to track the sun 1 in order to optimally use the sun's rays to generate energy or the like. These mechanisms are often very complex, require a lot of maintenance and are expensive to manufacture. Furthermore, in the known mechanisms there are large forces for aligning the photo 11 a i kmo du 1 e and the like for the 1 i ch.

From EP 2 963 357 a guide for P hotovo 11 ai kmo du 1 e is known which has a mast for direct or has an indirect arrangement of a support row, which is articulated by means of a pivotable joint about an axis of rotation, in which the support row has two rotatable joints, on which opposing forces have one zone for the rotation of the bearing unit are present, in which the force is achieved by means of a guide element 1 essentially with H a 1 circles and in which the radius of the guide element 1 essentially with H a 1 circle essentially corresponds to the distance between the force zone and the swivel joint.

 The device described in the publication EP 2 963 357 has some problems. In particular, the mechanism between the h a 1 k r e i s s e gme n t and the rope is exposed to stress and wear. Furthermore, a tension element is required, which in the present publication is a rope that has to withstand the force that is required for aligning the guide. In addition, the system requires an arrangement between tables with photo o 11 a i kmo du 1 e n and a control system that crosses the tables. This arrangement limits access with vehicles between the rows of ph o t o v o 11 a i kmo du 1 e n and / or makes it very competitive 1 i z i e r t.

A mechanism for aligning a large number is also known from the publication WO 2010 116007 by N a ch f h rv orri ch do ge n who wear Ph otovo 1 tai kmo du 1 e. These follow-up devices are arranged essentially parallel to one another.

 The individual T r a c k i n g devices are operated by an indirect connection via a chain. This mechanism is subject to stress and wear. In this case, too, the chain is exposed to high loads. Therefore, a larger thickness is required. In systems with large dimensions, this thickness of the chain can become a problem due to its weight, and for the management of the mechanisms, these gears can also generate bending moments and torques, which damage the mechanisms and structures used in the feed systems can cause.

US 2011 02 08 326 describes a structural support and a follow-up device with a platform which can be aligned by means of a cable system in which the platform is aligned by means of the rope. In the system described, one or more cables are operated and / or sometimes by means of a mechanism, and this movement aligns the platform on which the ph otovo 11 ai km o du 1 e are arranged. This system also poses problems, since the control mechanism of the ropes is very complex and by deflecting the ropes the ph otovo 11 ai kmo du 1 e are aligned, a reduction in the force needed to control the mechanism is not taught. In addition, the mechanism disclosed only aligns one of the following. In the device disclosed, a motor for aligning and tensioning is provided for each rope.

 An almost identical structure is also described in GB 2488105.

 From CN102073321 a guide for ph o t o v o 11 a i kmo du 1 e is known. However, this device generates high actuating forces, since the moments that occur, for example, are caused by wind directly or via a crevice guide onto the adjusting rope and from this in turn directly onto the connecting link 1 between several adjusters and the drive is derived. The resulting high actuating forces require large mechanical dimensions.

A second guide is also known from EP 2 837 899. With this device, the actuating forces are passed on directly to the actuating ropes, which in turn creates large loads.

 KR 20150026296 also describes a follow-up, whereby in this case the forces at the articulation points of the device are also directly directed to the control cable.

All of the systems described do not solve the problem, several adjustments due to a simple and easy adjusting mechanism to actuate, since they either pass on the wind forces and similar forces acting on the Ph otovo 11 ai kmo du 1 e to the control cables without much reduction, and there is therefore a risk that the Ste 11 me ch anis must be damaged by these forces , or that due to the lack of control cables, each table needs its own drive unit.

 Within the scope of the present invention, ropes, cables, wires, in particular

Meta 11 wires, tapes, chains and the like to be understood as ropes.

 Ph o t o v o 11 a i kmo du 11 i s ch e and / or support modules and Ph o t o v o 11 a i kmo du 1 e can also be carried and swiveled by several tr a g s t ru c t u r e s.

 It is an object of the present invention to produce a table which is used to align a long or several separate tables by means of a large number of guide devices via a central control system Anis must enable low actuating forces in accordance with the preamble of claim 1.

A mechanism according to the invention is proposed, which comprises at least one table for Ph otovo 11 ai kmo du 1 e, which is pivotably supported by at least one supporting structure and with at least two guides The table or tables is pivoted around at least two distant pivot points, the alignment being over a range of 1 centimeters be aligned between the block and tackle.

 The mechanism comprises at least two guides, two control cables, which can be operated by one operator.

 At least two devices are provided for each follow-up, which are connected to the respective control cables, and the alignment cable between the table and the support structure forms a pulley block.

 The aligning cable translates the movement of the table by means of the pulley, whereby a movement at the attachment points of the table results in a multiple movement of the alignment and thus the control cable. The actuating forces are reduced by this multiple. Since ropes work on a train, the two alignments (103, 104) work together to form the pulley blocks around the table.

 By rolling on at least one Ro 11 e / F 1 as ch enzug and / or a post is connected to a pulley and / or is arranged on several rollers / pulleys, which clean with the structure and / or the table of the next ch device are connected and guide the alignment cable and are deflected at least once by a deflecting element.

 In spite of 1 h a t t e r i s e, the attachment points of the F 1 a c h n z u ge s lie on the table and on the

Support structure distant from the fulcrum. It follows from this that there are several anchor points of the bottle on the table / on the support structure that are close to each other relative to the distance from the pivot point.

Advantageously, the outlines are by means of a clamp or other

Clamping devices with the s e e r s e i 1 e n, in particular releasably connected. In this way, the at least two control ropes can be arranged over the entire length and the alignment line for the respective guide lines for Ph otovo 11 ai kmo du 1 e / tables with Ph otovo 11 ai kmo du 1 en. First of all, the control cable can be formed from a pair of ropes and the outlines are connected to the pairs by connecting them together. In a further embodiment, additional ropes can be added.

 The preferred embodiment with pairs of controls spaced apart has some significant advantages. First, the alignment rope is there with two

Control cables is connected and these are connected to one another, not exposed to any rotation of the cable, which could generate force moments, in particular from torques or tensions on the alignment cable and thus on the entire system. In addition, the forces are applied to two control cables and the diameter of the individual in this way Rope can be reduced. In particular, only steel wires could also be used to control a large number of follow-up devices.

First of all, they are

After guiding you with one or more tables with photos o 11 a i kmo du 1 e /

P o t o v o 11 a i kmo du 1 e n, essentially arranged along a single straight line. In this way, they can easily be controlled centrally and all

After that, evenly follow the

Movement of the sun.

 The pulley blocks formed by the alignment allow the tables to be aligned, which reduces the effort required. Even if the alignment line and therefore also the control cables have to make a longer movement in order to align tracking devices, the entire system requires smaller dimensions and a drive device with less force in order to align the tracking devices do exactly that.

First of all, the control ropes on a drum are w e w i c ke 1 t. That which advantageously aligns the arrangement between the block and tackle and the adjusting cable

Around 1 e n ke 1 eme n t is an aligning reel or a variety of aligning reels that align the ropes and undesirable

Power transmissions and undesirable moments combine. Both the at least two control cables and the at least two control cables 1 e can be connected at the respective ends or formed by a single cable.
