Problems solved by technology

The disadvantage is that the transmission is exposed to atmospheric influences without protection
For example, flying sand gets into the transmission, which leads to premature wear
The transmission is also exposed to rain without protection, which causes severe corrosion

Embodiment Construction

[0019] figure 1 with figure 2 A device for harvesting solar energy is shown. This device is used in solar tower plants to reflect sunlight onto a central absorber or receiver at the top of the tower. A solar tower plant may contain hundreds or thousands of such heliostats, so the low-cost manufacturability of the inventive device is particularly advantageous.

[0020] The device comprises a column 9 (frame) on which a drive unit is arranged, comprising a motor drive 17 for elevational movements as well as a transmission 4 and a motor drive 18 for azimuth movements. The drive 17 pivots the carrier 3 together with the receiving device 1 about an elevation hinge with a horizontal axis 7 . The drive 18 oscillates the carrier 3 together with the receiving device 1 about an azimuthal hinge having a vertical axis 22 coaxial to the tubular support 9 . The carrier 3 forms a capsule 5 which serves as a cover for the entire drive unit including the drives 17 , 18 and the transmissio...

Abstract

The device has a receiving unit (1) which is provided for receiving the solar energy. The receiving unit has a receiving element (2) in the form of a collector, a solar cell or a reflector. A carrier (3) is provided for supporting the receiving unit, and a gear box (4) is provided for adjusting the carrier together with the receiving unit, taking place as a function of the sun tracking. The carrier comprises a capsule (5) which is arranged inside the gear box.

Description

technical field [0001] The invention relates to a device for harvesting solar energy, which includes: a receiving device for receiving solar energy, a carrier for carrying the receiving device, and a Highly tracked gearing. [0002] In this case, the receiving element can be a collector, a photovoltaic solar cell or, preferably in the case of a solar thermal power plant, also a reflector or a mirror. Background technique [0003] DE 10 2006 027 152 A1 describes a solar energy harvesting device, the transmission of which includes a ring gear with an external toothing. The transmission is additionally equipped with a pinion, which meshes with the external toothing of the ring gear. The disadvantage is that the transmission is unprotected from atmospheric influences. For example, flying sand gets into the transmission, which causes premature wear. The transmission is also exposed to rain without protection, which causes severe corrosion. Contents of the invention [0004...
