Abstract:
A system for orientation of a ring (20) by rotation, including a cable (38) engaging the ring (20) which rotates about a ring axis (X), a motor assembly (31) providing a first rotation reduction, and a stretcher (32) for stretching the cable. The system has at least one proximal pulley (34) and at least one distal pulley (36) rotating about a pulley axis (P), each pulley having grooves (40) configured for receiving the cable (38) therein. The ring is rotated by the motor assembly (31) and the pulley assembly (28) is configured to provide a second reduction of rotation to the ring (20) relative to motor rotation, whereby the ring (20) is driven via at least a double reduction of rotation relative to rotation of the motor, and the cable, the plurality of pulleys, and the ring provide a one-way mechanism.
Abstract:
The solar installation has at least one supporting framework (1) and a plurality of solar modules (S) fastened thereto. The supporting framework (1) has a tubular basic body (2) which can be rotated about the longitudinal axis (L) so that the modules can track the sun. The tubular basic body (2) extends over the entire length of the supporting framework (1). In order to be able to connect the tubular basic body (2) to a further supporting framework (1a, 1b) or to provide it with a bearing point, the tubular basic body (2) is provided on both sides with a respective flange (10, 11).

The invention relates to systems and methods for controlling angular position of a pivotable platform relative to a radiation source. In one embodiment, an apparatus for controlling angular position of a pivotable platform relative to a radiation source includes a frame, a thermal actuation element coupled to the frame, a pivotable platform positioned between the radiation source and the thermal actuation element so as to at least partially block energy from the radiation source from impinging on the thermal actuation element, and apparatus for pivoting the pivotable platform in response to a thermally controlled deformation of the thermal actuation element.
Abstract:
In order to make it easy to install a tracking device for a photovoltaic system, in which a horizontal tracking device is positively coupled to a vertical tracking device by mechanical means, preferably two adjusting mechanisms are provided. One adjusting mechanism is used for rotationally moving an elevation element (22) about a vertical axis (6) relative to an anchoring element (14). The second adjusting mechanism is used for also rotationally moving two sections (36A, 36B) of a mast (16) about a vertical axis (6).

Abstract:
According to the present invention, a floating structure control device is provided, wherein the device comprises: a floating structure which is installed to float on the surface of water; a post which is penetrated through the center of said floating structure, and is erected and fixed to induce rising and falling of said floating structure according to a water level; a floating structure rotating means which has one pair of first and second power units installed on the ground, and one pair of first and second wires that cross each other by allowing both ends thereof to be respectively connected with the first and second power units and said floating structure; a wire-winding measurement means which is fixed to correspond to said first wire on the ground, and measures the winding quantity; and a control means which is connected with said wire-winding measurement means, and forward controls the operation of said one pair of the first and second power units according to a reference angle in accordance with the orbit of the sun by season. Thus, the invention can precisely control the rotation of the floating structure according to the orbit of the sun.
Abstract:
An apparatus for solar tracking using minimal energy is described. A prismatic energy harvester (10) is positioned above a spring (20). The harvester has a pair of ears (14) at both side of the top portion of the harvester. The ear is moved by strings (16) from a reel (18) connected to a box of motor (12). At least two photo-resistive elements track the sun rays intensity to identify the position of the sun. Then, the motor adjust the reels to rotate the harvester using strings until the harvester and the sun is at right angle. The photo-resistive elements continuously track the sun so that the harvester can be rotated towards the sun at right angle.
