<P>PROBLEM TO BE SOLVED: To provide a trough excelling in wind resistant performance, operable by low power and allowing automatic washing. <P>SOLUTION: Wind resistant performance is enhanced by using divided type primary reflecting plates 1. Reduction of power is achieved by tracking the sun with a large gear 3. The reflecting plates can be washed automatically by using a mechanism of fixing a heat collection pipe 6 and allowing rotation of the entire troughs. As a heat collection mechanism, divided type primary troughs 1 are used and sunlight is collected to the heat collection pipe 6 in which a heat medium is made to flow. When all sunlight cannot be collected by the divided type primary reflecting plates 1 alone, a secondary reflecting plate 2 is used. If they still cannot collect all sunlight, by increasing reflecting plates unlimitedly in a manner of a tertiary reflecting plate and a fourth reflecting plate, sunlight can be collected to the heat collection pipe 6. <P>COPYRIGHT: (C)2013,JPO&INPIT |
