Description

fae.i

The invention relates to solar technology and can be used for the alignment of solar furnaces.

The aim of the invention is to accelerate the alignment process while improving its accuracy by using absolute benchmarks, eliminating systematic errors and simple instrumental solution.

Figure 1 shows the optical alignment scheme of a solar furnace with structural elements and a device for adjusting a solar furnace; figure 2 is a fragment of the device for adjusting the solar furnace.

The method of adjusting the solar furnace is carried out by successive illumination of the facet 1 (Fig. 1) of the concentrator 2, optically coupled to the facet 3 of the heliostat 4, rotation of the face, and the position of the focal spot of the concentrator 2.

Facets 1 of hub 2 illuminate with a collimated beam 5, additionally light with a collimated beam 6 each facet 3 of the heliostat 4 and control the position of the reflected radiation beam, while lighting is carried out in the direction coinciding with the direction of the optical axis 7 of the hub 2.

The device for adjusting the solar furnace contains adjustment units (not shown) of the positions of the facets 1 and 3 of concentrator 2 and heliostat 4, respectively, the illuminator 8, facets 1 and 3, and the receiver 9 of the radiation reflected by facets 1 of the radiation concentrator 2, located at the focus of the concentrator 2.

The device is equipped with a movable bath 10 with a magnetic plate floating in it 10 and a receiver 12 of radiation reflected by the facets 3 of the heliostat 4 radiation, and the illuminator 8 is equipped with a collimator and mounted on the platform 11 (figure 2), and the receiver 12 is made in the form of a ring and is located on the illuminator 8 (figure 1) coaxially with its collimated beam 6.

The device is also equipped with a drive 13 of the bath 10 and adjustment screens 14 and 15 with dashed centers.

Illuminator B is made in the form of a laser installation, equipped with a limb 16 and may have two working ends with tufts 5 and 6, respectively.

The alignment of the solar furnace is carried out as follows.

The actuator 13 (Fig. 1) establishes the bath 10 so that the illuminator 8 with beams 5 and 6 interacts with the facets 1 and 3 of the concentrator 2 and the heliostat 4, respectively. In this case, the directions of the beams 5 and 6 are set in the absolute coordinate planes of the local horizon and the earth's magnetic meridian due to the liquid bath 10 and the magnetic platform 11, and the specific direction of the beams 5 and 6 is set by the limb 16 along the geographic meridian.

Using screens 14 and 15, the direction of the beams 5 and 6 is adjusted.

The beam 5 illuminates the facet 1. With the latter, before the maximum signal is received from the receiver 9, it is adjusted.

The beam 6 illuminates the facet 3. With the latter, before the minimum signal is received from the receiver 12, it is adjusted. - The invention allows not to have a geodetic network, except for the orientation elements of the optical axes of the concentrator and heliostats, which simplifies the alignment.

Separate adjustment of the concentrator and heliostats from one direction eliminates the systematic alignment of the alignment of the concentrator, which improves the accuracy of the adjustment.

The transition from one facet to another is accomplished by simply moving the adjustment device, which shortens the adjustment time.
