Automatic receiver can be widely used as an autonomous source of energy in the lower latitudes with a lot of sunny days with the intensity of the solar flux of 1 kW / m 2. receiver design, consisting of a system of two co-axial parabolic mirrors with a common focus, the two rotary mechanisms for horizontal and vertical turning mirrors with electric drives, flexible optical fiber, one end of which is free to move in a stationary light guide which directs light energy to the consumer, and a control system consisting of two consecutive follow-up systems for vertical and horizontal turning mirror system while tracking the sun moving across the sky during the day, the sensor light intensity, logic block, consisting of two relays and performs launch function, stop, reverse and refresh the memory of the duration of the day and the maximum declination of the sun above the horizon. The receiver is fully automated and requires no human intervention during the operation, in addition to preventive maintenance and troubleshooting. The mechanical part of the receiver enables and automatic control system allows you to receive solar energy without direct human involvement during the day, and transport it to the consumer, regardless of the breadth of the earth, on which the receiver and the time of year, which saves electricity.

DESCRIPTION OF THE INVENTION

The invention relates to solar energy and may be used in the design and operation of solar receivers it with transportation to the consumer without direct human intervention.

The prior art known controllable solar energy receiver comprising two coaxial parabolic mirror with the same tricks two mechanisms mirror axis orientation to the sun and the flexible light guide mirror.

This decision is the closest to the proposed solar energy receiver.

The lack of automatic control technique and the method of transportation of solar energy to the consumer is a brake on the development of solar energy in general.

An object of the invention is to provide a fully automatic solar receiver Enhanced density with the ability to transport it to the consumer at a distance, without direct human involvement with a small team operating personnel during operation.

The greatest effect of the introduction of the proposed receiver can receive if they assemble in the most lit areas with the highest density of solar flux without darkening adjacent objects (on the roofs of tall buildings in the cities, in the mountains, in the open countryside, on ships, and so on. D.) .

The most cost-effective use of solar energy - indoor lighting during the day (the subway, warehouses, ovoschehranischah, the holds of ships, etc.), which will lead to a reduction in electricity used for lighting in half a year.

The technical problem is solved by the fact that the mechanical part of the receiver enables and automatic control system provides continuous reception of solar energy throughout the solar day from sunrise to sunset in the optimal range (axis mirrors coincides with the direction of the sun at the time of moving it across the sky) regardless of earth latitude and time of year, and the transportation of it and to the consumer.

The invention consists in that in the automatic receiver of solar energy, which includes two co-axial parabolic mirror with coincident foci, two mechanisms mirror axes orientation to the sun, and a flexible mirror optical fiber according to the invention the orientation of the mirror axis are produced in the horizontal and vertical directions, and the the receiver further comprises a stationary mirror light guide and the automatic mechanisms of orientation control, consisting of sensor intensity of the solar wind, the clock mechanism with an electric linear angle sensor, two consecutive follow-up systems to restore mirror axis of the sun, the logical unit consisting of two relay to start at sunrise and stop at sunset, but also to upgrade the memory of a sunny day duration and maximum angle of declination of the sun above the horizon, the functional blocks to determine a maximum angle of declination of the sun above the horizon to change the time scale and a sinusoidal input into a vertical tracking system that provides an angle of declination sun in the vertical direction, the flexible optical waveguide having one end freely movable in the stationary optical fiber, for the orientation axis of the mirrors in the sun uses the principle of the guidance barrel anti-aircraft machine guns or anti-aircraft gun at the target with horizontal and vertical rotation of the barrel, to a horizontal servo system input is set by clockwork through the line angle sensor in the range of 0 o -360 o, to automatically turn on the tracking systems at sunrise and off at sunset using a signal from the solar flux intensity sensor relay P 1 switching, vertical servo system input signal is sinusoidal with rescaled time so that at the end of reception time after sunset, he vanishes, and was the highest, to bring the control system in the middle of the day in its original state when the mirror axis is directed to the point of sunrise horizon, using the second relay P 2, which performs fast reverse a horizontal servo system, it clears the memory and replaces with new values ​​the time duration of the solar day and the maximum declination of the sun above the horizon, and to form the input vertical servo system in the control system has a block of memory declination angle of maximum sun above the horizon with the input from the angle sensor the output shaft of the vertical rotation drive gear system of mirrors and access to the multiplier.

Thus, the system of automatic solar receiver control consists of two series-connected servo systems for horizontal and vertical cornering foster a system of mirrors, sensor solar flux intensity, logic block, consisting of two relay P 1 and P 2, provides automatic start, stop, reverse horizontal servo system, bringing it to its original state, the divider and multiplier device level memory extremum, sine wave block and the level of remembering the time duration of the solar day and the keys K 1 +, K 2 +, K 1 -, K 2 - for manual control of the sun when you start the system to the max readings meter solar flux intensity I.

automatic receiver work begins with the initial start-up. In this case, by pressing 1, K +, K 2 +, K 1 -, K 2 - when the sun sets the position of the point of sunrise horizon, combining the mirror axis in the direction of the sun at solar maximum flow rate, which is measured at the meter I.

After that, the control system is included in the automatic mode by yourself at the time of sunrise.

Since the mirror axis is directed to the point of the horizon, close to sunrise, when the appearance of the last strong intensity of solar flux increases and the start relay P 1 includes tracking systems for horizontal and vertical cornering mirror axis, ensuring that it is the direction of movement of the sun across the sky during the day, up approach, providing a maximum density of the solar flux arriving at the receiver mirror.

At sunset on the horizon the intensity of the solar wind drops to zero and the relay P 1 disables both tracking systems, but this time for a short period of time t switch P 2 includes a horizontal servo system Reversing system, bringing it to the starting point of the horizon, that is, sunrise point, the length of time clears the memory of the day by entering a new value in the memory divider, which serves as a link time-warping, clears the memory of the maximum declination of the sun above the horizon angle v and replaces it with a new value. Relay coil P 2 is switched to the voltage U t, derived from the time of the sensor, standing on the clockwork axis at time t = T d, ie, when disconnecting relay P 1 due to discharge of the capacitor in series with the relay coil P 2 at a time t. This time depends on the relay P 2 parameters, capacitor and resistance, which are selected experimentally or calculated.
