Description


   <Desc / Clms Page number 1>
 



  Mirror construction for capturing and concentrating solar radiation. The invention relates to a mirror structure for collecting and concentrating solar radiation, which construction comprises a frame, at least one elongated transversely curved mirror with a concave specular surface, which is rotatable about a geometric axis parallel to its longitudinal direction frame is mounted, and means for revolving the mirror relative to the frame.



  Mirror structures of this kind are or form part of solar heating devices in which either a convex mirror or an object to be heated is arranged on the focal line of the mirror. In the first case, the convex mirror reflects the concentrated solar radiation through a slit in a closed space, for example a plant growing cabinet. In a second case, the object to be heated

 <Desc / Clms Page number 2>

 usually a pipe through which fluid to be heated flows, for example liquid sodium or steam, which fluid is then often used for driving heat engines, turbines, etc.



  The mirror must of course be rotatable in order to be able to receive maximum solar radiation at different positions of the sun.



  In these known mirror structures, the axis of rotation of the mirror lies on the mirror itself, by extension or on the back of the mirror. This is the case, inter alia, in the mirror constructions according to the Belgian patents No. 888 400 and No. 901 638. In the mirror construction described in the Belgian patent No. 901 638, for example, the mirror is a half parabola and the axis of rotation is located in the apex of this parabola .



  The result is that in all these known mirror structures the focal line shifts with a rotation of the mirror relative to the frame. In many cases this can cause problems. For example, if a conduit for fluid to be heated is arranged on the focal line, then this conduit also moves when the mirror is rotated, so that both ends of the conduit must be connected to the rest of the solar heating device.

 <Desc / Clms Page number 3>

 flexible connecting pipes that usually have to withstand relatively high temperatures. This makes the construction more complicated and expensive.

   The object of the invention is to overcome these drawbacks and to provide a mirror construction for collecting and concentrating the sun's rays, whereby the focal line remains in place when the hollow curved mirror is rotated.



  For this purpose, the geometric axis of rotation of the mirror is located on the focal line of the mirror, and the means for rotating the mirror include at least one auxiliary structure mounted on the side of the mirror remote from the axis of rotation, of which auxiliary structure the outer circumference part of a circle with this axis of rotation as its center, and means for moving this auxiliary construction.



  Because the focal line coincides with the axis of rotation, it also remains in place when the mirror is turned. The means for revolving the mirror can be carried out very simply and the mirror can also be supported very effectively.



  In a special embodiment of the invention, the mirror is curved according to a parabola.

 <Desc / Clms Page number 4>

 



  The invention is especially useful if the mirror construction includes a fluid conduit extending along the focal line.



  Other details and advantages of the invention will become apparent from the following description of a mirror structure for collecting and concentrating solar radiation; this description is given by way of example only and does not limit the invention; the reference numbers refer to the attached drawings.



   Figure 1 is a perspective view of a mirror construction according to the invention; Figure 2 is a side view of the mirror structure of Figure 1, drawn to a larger scale.



  In the two figures, like reference numerals refer to like elements.



  The mirror construction of the figures is a solar heating device for heating fluid flowing through a conduit.



  This conduit 1 extends along the focal line of a series of six elongated mirrors 2 arranged in their

 <Desc / Clms Page number 5>

 are curved transversely according to a parabola and whose mirror surface is hollow.



  The mirrors 2 may, for example, consist of a core of rigid foam plastic which is mounted in a frame and which is coated on the mirror side with a mirror coating, such as a polished stainless steel plate.



  The mirrors 2 are supported by a frame which mainly consists of seven vertical, almost triangular supports 3, which bear a bearing 4 at their top. A mirror 2 is mounted portable between two adjacent supports 3. To this end, each mirror is mounted at both ends on a number of arms 5 extending transversely of the longitudinal direction of the mirror and meeting at the focal line of the mirror on a round stud 6 with one end bearing in the bearing 4 of a support 3. Two of the arms 5 are in line and extend between the outer edges of the mirror 2. A third arm 5 extends perpendicular to the aforementioned arms 5. Each tap 6 is provided with a central opening through which the conduit 1 extends so that the tap 6 is freely rotatable around the conduit 1.

   Halfway along its length, each mirror 2 is provided on its back with an auxiliary construction 7 which is oriented transversely to its longitudinal direction and which is formed from an outer edge and a lattice construction located between this edge and the mirror. The

 <Desc / Clms Page number 6>

 outer periphery of the outer edge extends along a portion of a circle the center of which is on the focal line of the mirror 2. The outer edge is serrated on the outside. The teeth of this outer rim engage a gear 8 which is mounted on a drive shaft 10 in a ground mounted gearbox 9.



  This drive shaft 10, which extends in the longitudinal direction of the mirror construction, is common to all the gears 8, which means that all the gears 8 are rotated at the same time and therefore all the mirrors 2 tilt at the same time.



  The drive shaft 10, in turn, is driven by a motor 11 mounted on one end of the shaft on the ground.



  The tilting of the mirrors 2 thus takes place simultaneously in a very simple manner. All mirrors 2 are very well supported. Because the pipe 1 is located on the focal line of the mirrors 2, this pipe does not change position during the tilting of the mirrors. Because the taps 6 can rotate around this pipe, the pipe 1 can be fixed, so that the connection of this pipe to the rest of a circuit for fluid can be done by means of fixed connections and thus in a cheap and leak-free manner. The pipe 1 can move freely in the longitudinal direction in the studs 6 and can

 <Desc / Clms Page number 7>

 so expand and contract freely. The mirrors 2 are always directed towards the sun. The received solar radiation is concentratedly reflected on the focal line, that is to say on the pipe 1, which heats up the fluid flowing through it.

   For example, the conduit itself may consist of a metal tube surrounded by glass that transmits the solar radiation to the tube but limits heat radiation back. The pipe is supported by the taps 6.



  The invention is by no means limited to the above-described embodiment, and within the scope of the patent application many changes can be made to the described embodiment, including as regards the shape, the composition, the arrangement and the number of the parts used to realize the invention can also be used.



   0 In particular, the mirror construction need not necessarily contain just six mirrors. It can contain any other number of mirrors and even just one mirror.



  The displacement means of the auxiliary structures for tilting the mirrors which do not necessarily include a gear transmission. The transmission between the drive shaft and the auxiliary structures can also be effected, for example, by means of rollers.
