The disadvantage of this device is the drives made of metal with memory, since in order for the metal to take its previous shape, certain conditions must be created, such as high temperature.

The closest in technical essence and the achieved result is a solar space power station located in a near-earth geosynchronous orbit (the orbit of a satellite orbiting the Earth, in which the period of revolution is equal to the stellar period of the Earth's rotation - 23 hours 56 min 4.1 sec. [Geosynchronous orbit www.wikipedia .org]), consisting of load-bearing structures on which thin-film solar batteries are mounted, which perceive the flow of solar radiation and convert it into direct current electricity, which is made up of a longitudinal base portion, on which are attached perpendicular to the branches in the same plane, said cylindrical structure assembled from lightweight folding airtight shells blocks of a flexible deformable material attached to them outside the thin-film solar cells, and on the inside by linear stiffeners. [Patent RU 2094334, MKl. B64G 1/00 of 04/18/1994 (prototype)]

The disadvantage of this device is thin-film solar panels, as they are less reliable than conventional photo panels, and have a lower coefficient of strength.

The aim of the invention is to increase the productivity of energy transfer, its cost reduction and increase the area of solar energy coverage of areas on Earth that consume this energy.

This goal is achieved by the fact that the solar space power plant, which consists of supporting structures on which solar panels are mounted, is a solar collector that receives a stream of solar radiation and converts it into direct current electricity, and a remote energy transfer unit, while the solar collector is deployed, which at the same time it is also a power source of the station, made in the form of a polygon photopanel with an even number of angles, consisting of a large square photographic plate, four the back of the main rectangular photographic plates and eight main triangular photographic plates, and an additional multilobe polygon mechanism, consisting of auxiliary square and triangular isosceles photographic plates.

In the folded state, the solar collector is a cube with connections from automatic hooks and loops that are disconnected in the folded state, and when unfolded, they are connected. The remote energy transfer unit is a beam of antennas interconnected so that they direct energy to one common point where an amplifier is located that redirects the energy beam to Earth. On Earth, energy is received by existing power plants, which host receiving equipment. The solar collector consists of a photo panel in the form of a polygon with an even number of angles, to each side of which are connected square and triangular photographic plates. A solar collector that receives energy is also a power source for the solar space power plant itself. The solar collector is fully automatically deployed in outer space through a multi-leaf opening mechanism. The remote power transmission unit is an antenna beam. As power receiving stations, already existing power plants are used, on which receiving equipment is located.

The technical result provided by the given set of features is to increase the areas of solar energy consumption by ground-based solar stations that process the received radiation into electrical energy, and its cost reduction.

Solar space power plant operates as follows.

The energy of solar radiation is supplied to the solar collector - 1, which receives a stream of solar radiation and converts it into direct current electricity. A smaller part of all the received radiation goes into the battery for operation of the receiving-converting equipment located in the station building - 2, the rest of the energy goes into the battery, designed to transmit energy to the Earth, as shown in the diagram in FIG. 16. If the battery is completely full, then excess energy enters the buffer. Then, the energy is directed to microwave generators and to a beam of microwave antennas - 3 with microwave emitters - 28 using the remote energy transfer unit, the beams transmit energy to the Earth at a given time and a given place, taking into account the distance and time of energy passage between the SCES and receiving station, as well as the location of the station on Earth and atmospheric interference. Accepted energy on the recten Earth is converted into direct current energy and sent to the consumer.

After the launch of the solar space power station (SCES) to a specified location, the solar collector - 1 automatically unfolds, after the glue (indicated by bold dashed lines) all melts. The solar collector - 1 consists of auxiliary square - 9 and auxiliary triangular photoplates - 8, which make up square petal photographic plates - 13, the sizes of which are determined based on the lengths of the sides of the octagon - 4, which consists of a large square photographic plate - 5, the main rectangular photographic plate - 6 , the main triangular photographic plate - 7. When assembled, the solar collector -1 is a cube (Fig. 10), which is connected to the station building - 2 main square photographic plate - 5. All photographic plates are fastened Lena among themselves with telescopic flexible mounts - 10, which is indicated by thin dash-dotted lines. First, the petals of the solar collector - 1 are assembled, consisting of auxiliary square - 9 and auxiliary triangular photoplatsins - 8, while the telescopic flexible mounts between them are folded, as shown in FIG. 5.

Connections consisting of automatic hooks - 11 and loops - 12, shown in bold solid lines, are initially disconnected. Then, when the telescopic flexible mounts - 10 fold up, the automatic hook - 11 enters the loop - 12 and closes, as shown in FIG. 8.

An automatic hook works as follows: a loop - 12 moves up the shutter - 25 with a hollow cylindrical arc - 22 and a piston - 21 located in the hook body - 20, extrudes a cylindrical arc - 23 until the locking tip - 24 gets into the lock - 19. By this principle, the entire solar collector - 1 is assembled, however, telescopic flexible mounts between the polygon - 4 and its petals - 13 do not add up entirely, but unfold the petals - 13 so as to get the maximum energy from the Sun. After the solar collector - 1 has turned around, it begins to receive solar energy, and 10% of the energy received goes to the power plant itself.

The energy received from the Sun by a solar collector - 1 is converted into a station - 2 case and supplied to an antenna beam - 3, which consists of several parabolic antennas - 26, for example, the microwave range (there are 5 of them in this example) attached to the station case - 2 as shown in FIG. 1 and FIG. 15.

The conversion of solar energy to microwave radiation occurs according to the circuit shown in FIG. 16. Solar collector - 1 receives solar radiation. It is distributed in two directions. A smaller part enters the battery, designed to power the space segment of the SCES. Most of the energy received is transferred to an accumulator intended for broadcast to the Earth, and if this accumulator is full, then excess energy is transferred to the buffer. Then, on command from the control device, the energy is supplied to microwave generators and to the antenna beam - 3.

Parabolic antennas - 26 with microwave emitters - 28 are bonded to each other so that they direct microwave radiation to one common point where the remote energy transmission unit -27 is located, which amplifies the energy of microwave radiation and transmits it to Earth.
