DESCRIPTION:
BRIEF SUMMARY
The invention relates to a solar radiation collection apparatus and more specifically a solar energy plant having a reflector which is adjusted to follow the path of the sun.
In U.S. Pat. No. 3,861,379 a solar collector is described which possesses for the control of tracking of the sun a photoelectric arrangement which is coupled to an adjusting mechanism via an electric motor. A second photoelectric arrangement is present so that in the case of an overcast sky, the rotation signal emanating from the first photoelectric arrangement for the electromagnetic arrangement is interrupted, and in this way a rotation of the reflectors is avoided. A time switch energized at the end of the day ensures that the motor causes the reflectors to return to the morning position. Such a suntracking system is complicated and accordingly expensive.
In CH patent specification No. 627,259 a solar collector having a solar radiation focusing reflector is described. Parallel to the axis of rotation of the reflector, an elongated absorber is disposed for receiving the solar radiation focused by the reflector. Sun-tracking means reacting to the solar radiation and actuating the adjusting mechanism are further provided for keeping the focusing of the solar radiation on the absorber. The sun-tracking means comprise two elongated sensor containers situated opposite the reflector and, viewed from the reflector reciprocally, extending at least for the most part on opposite sides of the absorber. In each of the containers there is a working medium which is, in operation, partially in the liquid phase and partially in the vapor phase, the vapor pressure of which is, through an evaporation-condensation process, proportional to the amount of solar radiation received from the respective container and from the reflectors. The two working-medium pressures are mutually and oppositely active upon the adjusting mechanism in such a way that a pressure differential occurring upon a deviation of the focusing at the absorber corrects the position of the reflectors for the said deviation. These known sun-tracking means are simpler in construction than the aforementioned sun-tracking means having photoelectric arrangements. On the other hand, however, pressure lines and two piston-cylinder drives are needed, which parts take up a relatively large space, and the installation of these parts is not exactly easy.
It is the task of the invention to provide an apparatus of the kind initially mentioned to which the mentioned disadvantages do not attach.
The invention is explained in more detail below, by way of example, with reference to the drawing.
FIG. 1 shows a solar energy plant having a reflector, an absorber, and an embodiment of the apparatus according to the invention in simplified perspective representation,
FIG. 2 another solar energy plant having a reflector assembled from strip-shaped reflector elements, an absorber, and another embodiment of the apparatus according to the invention in simplified perspective representation,
FIG. 3 the elementary circuit diagram of a first simple embodiment of the apparatus according to the invention,
FIG. 4 the elementary circuit diagram of a second embodiment of the apparatus according to the invention, and
FIG. 5 the elementary circuit diagram of a third embodiment of the apparatus according to the invention.
FIG. 1 shows a solar energy plant having an at least approximately cylindrical parabolic reflector 1 which is rotatable about a swivel axis 2. The swivel axis 2 is mounted in vertically disposed supports 3 and rotation-connected via a reduction gear 4 to an electric motor 5. In the region of the upper ends of the supports 3 an absorber 6 is rigidly disposed. The absorber 6 is an elongated container, preferably of a metal. The outer sides of the container are black so that as great a proportion as possible of the solar energy striking it is converted into heat. Provided for at each of the end faces of the container 6 is one pipeline 7, 8, respectively, each, over which a heat carrier, for example water, is
