The invention relates to solar power plants designed to convert solar radiant energy into electrical energy as in Sunny weather and overcast. Well-known solar power plant for the conversion of solar radiant energy into electrical energy, comprising vertical and horizontal shafts rotate, the latter of which installed solar photobacteria, which has a system of rotation of the shafts orientation fotomature in the sun [1]. Lack of power is low efficiency, because santalina the installation is done manually once a month or quarter, which corresponds to the average azimuth latitude and time of year. Turn power daily is carried out automatically by means of two cylindrical (left and right) thermoperiods heated by sunlight that has low reliability in conditions of low temperatures and high wind loads. The drawback is the complete lack of return the station to its original position evening-morning. Well-known solar power plant, comprising a vertical shaft driven azimuthal rotation, which is fixed to the Playground, and on the upper end of the said shaft above the platform has a horizontal shaft driven sanitarnogo rotation, which is fixed to Sol is ecna photobacteria, equipped with automatic system sanitarnogo and azimuthal drive sun tracking, including command solar cells low power relay Executive relay drives reversing engines [2]. The shortcoming is the low reliability in terms of the variable or temporary clouds, the impossibility of automatically installed in operating position in the morning. This is due to the fact that the witness device is performed on the solar cells placed in the tube. In a few minutes the clouds, in the absence of solar beam, this device is not valid, and after the clouds a ray of sunlight into the receiver device already misses and the station is no longer navigate by the sun, it is a failure. And when variable clouds during the day this can happen hundreds of times. Even in a Sunny weather with nightfall, the station looks at the sunset, and the morning sunrise from the East. The station cannot be deployed, requires manual focusing. The prototype of the invention is a solar power plant, comprising a frame in which is mounted a vertical shaft driven azimuthal rotation, and at its upper end has a horizontal shaft with automatic system sanitarnogo rotation, which is fixed to the solar photobacteria equipped with automatic system of the azimuthal drive track with lnam and spread from West to East [3]. The disadvantage of the prototype is a high intensity, complexity of construction and electrical automation systems, resulting in decreased reliability and increased cost of plant. The present invention allows to obtain a new technical effect - increased reliability, simplified electrical schematic of automation and drives twice. This technical effect is achieved by the fact that the automation system sanitarnogo rotation is made in the form of a fixed horizontal rings on said frame, inside of the ring made one sinusoidal groove, a horizontal shaft ends are provided with symmetrical Cam leashes, which are sinusoidal groove, and the groove is shaped so that its amplitude is smaller than the radius of the shaft to the eccentric leashes deviated by an angle of 45° in one direction or the other when moving along the groove. Figure 1 shows a General view of a solar power station. Figure 2 - node I 1. Figure 3 - cross section of figure 1 along a-A. Figure 4 - cross section of figure 3 along B-B. Figure 5 - cross section in figure 4-C. Figure 6 - scan position 14. 7 shows the electrical circuit of the power plant. The power plant consists of a frame 1, in which the thrust bearing 2 has a vertical shaft 3 with the leading toothed wheel 4 is in contact with the worm shaft 5 revere the top of the actuator 6 (M) DC. The shaft 3 can rotate in the bearing sleeves 7 of the frame 1. On the upper end of the shaft 3 has a horizontal shaft 8, on which is rigidly fixed to the side of the clutch 9, and on them on the brackets 10 solar photobacteria 11 (PV) power plant. Horizontal shaft 8 at the ends provided with symmetrical eccentric leads 12, which are in the same sinusoidal groove 13 on the inner surface of the horizontal ring 14, is rigidly fixed on the frame 1 by brackets 15. The amplitude of the sinusoidal groove 13 in the ring 14 must be less than the radius of the shaft 8 so that it leads 12 is rejected only at 45 degrees to one side when driving on the groove 13. On sun fotomature 11 (Feh)is fixed to the two side, left 16 (PL) and right 17 (AF) command of the solar cell. The solar cells 16 and 17 relative to the working surface of futabatei 11 (Feh) mainly installed at an angle of 250...255 degrees. On the reverse side of the solar fotomature 11 (PV) installed additional rear photocell 18 (FZ), mounted to the horizontal plane at an angle of half maximum sanitarnogo angle of the sun. The angles command photocells 16 and 17 are justified from the condition that relative to the sun's rays they are constantly under an angle of 15...20°with reflection to 39%, while the deviation of the sun on 15...20°, working angle with one from the pile is increased by this value, on the other decreases. Then with one hand reflected light rays comes 6,6...of 9.8%, with the other to 100%. This ensures the efficiency of the above-mentioned solar cells. The electrical circuit of a solar power station includes a sun fotomature "Feh" power plant, which through switch VK has pins + and - DC to the consumer. In the power supply system power connected battery "AK", may also be set voltmeter to measure the voltage of the solar fotomature "Feh". It is equipped with two azimuthal command photocells - right "Op" and left "FL", United to the opposite winding of polarized low power relay "WP1", and the command photocell "FL", installed on the back side of the solar orientation, which is connected to the winding of polarized relay "WP2". Intermediate low power relay "WP1 and WP2 have a neutral anchor with the left and right contacts of the circuit, in the circuit which has a winding of the actuating relay, respectively, "WP1"-"PC1" and "RS", "WP2"-"RHS". All Executive relay "PC1"..."RS" through anchor "WP1 and WP2 directly connected power stations and relay "RS has additional parallel chain, which includes normally closed contacts RC" and normally the property is built contacts RS". The normally closed contact of the output relay "PC1" and "R" connected to a single phase power supply, for example,"+", and normally open contacts to the other phase power supply, with each of these circuits is supplied normally closed contacts of the limit switches, respectively, "CL" and "Lam". Between anchors relay "PC1" and "RS connected reversing the motor "M" DC. While normally open contacts R" given in parallel, normally open contacts R". The power plant operates as follows. Solar photobacteria "Feh" power focuses on the sun light rays and produces the estimated electrical energy voltage and constant current. When the switch is activated "VK" provides power to the consumer and is charging the battery "AK", when the voltage drop across fotomature "Feh", such as in clouds or at night, provides consumers with power. The morning begins sanitarne and azimuthal movement of the sun. The sun changes the azimuthal position during the day from East to West. In this case, the angle of incidence of sunlight on the right photocell "Op" and the darkening of the left solar cell "FL". Right photocell produces a current which is udaetsya the relay coil "WP1", the latter responds and closes anchor "WP1" on the left-hand contact and puts the current winding of the actuating relay "PC1", which opens its normally closed contacts and closes the normally open contacts PC 1.1", thereby casts current reverse drive "M"(6). Last through the worm shaft 5 and the gear wheel 4 rotates the vertical shaft 3 to the right and turns the whole station on the azimuthal position of the sun. When the azimuthal alignment of the two photocell "Fi" and "FL" at a small angle to the sun produce the same small currents, which are balanced on the winding "WP1", the last drops and drops his anchor "WP1". The power supply circuit of the actuating relay "PC1" is de-energized, which releases its contact "PC1" and de-energizes the drive "M" (6). Azimuthal rotation of the station stops. Further azimuthal changes of the sun, the operation is repeated until sunset. When the azimuthal rotation of the vertical shaft 3 to the right, from morning to noon, respectively, it produces a rotation of the horizontal shaft 8, which is their leashes 12 slides on the internal sinusoidal groove 13 fixed horizontal ring 14. This leads 12 to the amplitude of the top and bottom of the sine wave groove 13 from position "a" to position "b" rise up and turn the shaft 8 at 90°, with the NGOs through the bracket 10 is rotated solar photobacteria 11 (PV) from a vertical to a horizontal position. This ensures sanitarne tracking the sun in the first half of the day. In the second half of the day continues azimuthal tracking the sun, i.e. the further rotation of the vertical shaft 3, respectively, and continues the rotation of the horizontal shaft 8, which is their leashes 12 slides on the internal sinusoidal groove 13 of the upper amplitude of the sinusoid at the lower amplitude of the sinusoid and the shaft 8 is reversed at 90° to the sunset, in the manner described unfolds solar photobacteria 11 (PV) from the horizontal to the vertical than is provided sanitarne tracking the sun in the afternoon. Power sleep "backwards" to the East. In the morning when the sun rays fall on the rear photocell "FZ" (18), the latter generates an electrical current to the relay coil "WP2", which its armature closes the supply circuit of the actuating relay "R". The latter closes its contacts RS" and cambiocorsa through normally closed relay contacts "RS", at the same time, the relay contacts "RS" is under current reverse drive "M" (6), through which the worm shaft 5 and the gear wheel 4 rotates the vertical shaft 3 to the left and turns the whole station up until the sun's rays will fall on the left photocell "FL" angle of 15...20°i.e. when the orientation is the station of the sun at an angle of 140...150° . The latter generates an electrical current to the coil "WP1" reverse direction and causes its armature to the right contact "WP1", thus casts the current Executive relay "R"that their contacts RS" interrupts the circuit of relay supply "RS, closes its contacts RS" and continues the reversal of the plant above described manner to equalize the illumination of the photocells as "Fi" and "FL". Accordingly deenergized relay "RS" drop their contacts RS" and "RS", the scheme comes in its original position. On weather conditions (clouds, rain) the orientation of the plant can be stopped in any position, for example at any time of the day between sunrise and sunset. In this case, the output of the sun rays falls or rear "FZ" or "FL", and the station is in any case will be guided in the manner described. Variable cloudiness azimuthal spread of the sun will occur due to the operation of the photocell "Op". If the orientation of the station ceased to azimuthal angle of the sunset more than 145...150°i.e. almost from morning to evening, evening rays will not bring the right photocell "Op", but will go on the rear photocell "FZ". Happens this way turn the station on the East (left). In this case, none of the "Fi" and "FL" will not fall under the rays of the sun. The station is going to be unfold until while pressed, and turns off the limit switch "CL" left turn restrictions, remaining in readiness to work with the sunrise. In the morning when the sun rays fall on the "FP" and described provides azimuthal right turn power plant, when this is released limit switch "CL", providing the power supply circuit of the left turn. Throughout the supply circuit of the drive "M" rotation enabled limit switches "CL", "Lam", excluding emergency situations in the operation of the circuitry, as well as the possible operation at night from random light sources such as car headlights, searchlights, etc. Relay circuit can be assembled on an electronic relay. Circular rotation station is excluded to avoid the application of a number of slip rings. This ensures that the clock santalina and azimuthal self-orientation station, simplicity and high reliability. Sources of information: 1. Sunflower solar. NPP "Kvant", Moscow, 2002 2.
