FIELD: power industry.SUBSTANCE: method for obtaining heat and electrical energy includes focusing of the sun rays by concentrator on the fixed heat-absorbing surface, and further focus movement over it in accordance with sun movement, the heating medium heating through the heat-absorbing surface, and transformation of the obtained heat energy in the electric energy. The concave mirror is used as concentrator, the mirror is moved by sun tracking, at that the heat-absorbing surface is arranged at crossing of the vertical and horizontal axes, around which the concentrator is rotated during tracking. For the concentrator rotation relatively the vertical axis the first motor is started, as result the worn screw 5 starts rotation and turning of the tooth-wheel 2 together with platform 1. When the concentrator achieves the required position (azimuth), the first motor shutdowns. For the concentrator rotation around the horizontal axis the second motor is started, resulting in rotation of the shaft 14 with worn screw 13, that by means of the tooth-wheel 12 and connected with its worn screw 10 the gear sector 9 with axle 6 and wheel 7 rotates. At that by means of the chain-drive 8 the driven wheel 15 with horizontal axles 17 and concentrator is rotated to the required position, then it is locked by the motor shutdown. At that on the bottom part of the heat-absorbing surface of the sphere 19 a light spot of the concentrated sun rays is created, the spot moves over this surface during the sun tracking during day time.EFFECT: increased stability of the energy sources parameters, increased efficiency, improved operation characteristics.10 cl, 3 dwg |
