Embodiment Construction

[0026] Solar trackers for parabolic trough solar collectors (ie, PTCs) and thermal solar systems with PTCs will be described in this disclosure.

[0027] In the proposed solar tracker, when the conversion device of the solar tracker cooperates with the corresponding conversion device of the PTC, the one-dimensional operation motion is transmitted through the transmission device and converted into the pivotal motion of the PTC. The switching device of the solar tracker is adjustably connected to the transmission to facilitate individual adjustment of the angular position of the PTC.

[0028] In mechanical engineering, play (sometimes called lash or backlash) is the clearance or lost motion in a mechanism caused by the clearance between mechanical parts. In solar tracking mechanisms, this play can introduce tracking errors because the signal operating the motion of the drive does not correspond exactly to the position of the PTC.

Abstract

The invention provides a solar tracking arrangement and a thermal solar energy system. The solar tracking arrangement enables a plurality of parallel arranged PTCs (parabolic trough solar collectors)to be directed towards the travelling sun. The solar tracking arrangement can be connected to PTC and comprises a drive means, a transmission means, and a plurality of conversion means. The transmission means are connected with the drive means and to each of the plurality of conversion means. The transmission means is configured to convey an operating movement caused by the drive means to the plurality of conversion means, and each of the conversion means is configured to convert the conveyed operating movement into a pivoting movement of a respective one of the plurality of PTCs about a focusline, such that each of the pivoting movements directs the respective PTC towards the travelling sun. One or more of the conversion means are adjustably connected with the transmission means in a direction along the transmission means so that the angular position of one of multiple PTCs can be individually adjusted, the guide precision is improved, and the heat output is improved.

Description

technical field [0001] The present disclosure relates to energy supply and in particular to building solutions in systems for solar energy production. Background technique [0002] In modern society, human beings and industries consume a large amount of energy, for example, for the production of various products, transportation or the production of food. Energy can be generated in many forms or obtained from different sources. For example, electricity is usually produced by hydroelectric power plants, and coal, oil or natural gas are usually produced by burning them. Traditionally, heat has been burned locally or provided by district heating power plants. [0003] As the population grows and the demand for services increases, energy consumption has increased dramatically with a significant negative impact on our environment. Combustion produces large amounts of carbon dioxide and other greenhouse gases. Hydroelectric plants need to flood large areas, etc. [0004] In or...
