Description

The utility model relates to solar energy and can be used in solar power plants to convert solar energy into electrical energy, and in addition, it can be used as an individual power plant.
Known solar photovoltaic installation, which contains a supporting structure with a parabolic concentrator mounted on it, made of flat mirror faces, connected to the output of the solar tracking unit, as well as an extended photoelectric converter located along the focal line of the parabolic concentrator. An elliptical reflector is mounted coaxially with it on the supporting structure behind the parabolic concentrator, one focus of which is combined with the focus of the parabolic concentrator, in the second focus of which there is a photoelectric sensor, the output of which is connected to the input of the solar tracking unit. On the back side of each of the mirror facets, a flat reflecting element facing the elliptical reflector is installed on its longitudinal axis perpendicular to its surface (see RF patent No. 2222755 of 05.17.2002).
The disadvantage of this installation is that it has a uniaxial tracking system for the Sun, as well as the fact that it uses large-area photoelectric converters, which makes the installation more expensive due to the high consumption of expensive converter semiconductor materials. In addition, a combined guidance system on the Sun is used. Coarse guidance is carried out from an external processor using astronomical time and latitude, so any change in installation location requires reprogramming of the processor.
Known solar photovoltaic installation containing a solar battery with Fresnel lenses and receiving radiation photovoltaic cells, mounted on a mechanical system supporting the perpendicular position of the solar battery to the direction to the Sun and equipped with a solar battery orientation system to the Sun, characterized in that the supporting mechanical system is formed by two frames - base and suspended, of which the base frame is mounted to rotate around a vertical axis, o leaning on the underlying surface using wheels, one of which is equipped with an electric drive, and the suspended frame is mounted to rotate around a horizontal axis from the electric drive, while the solar battery itself consists of modules with solar concentrators located on the suspended frame in the form of steps, and the orientation system The battery contains the primary and secondary solar position sensors, the main of which consists of a shading screen with a hole and eight cascade type solar cells, four of which located on the right, left, top and bottom on the outer sides of the screen and form azimuthal and zenith coarse guidance channels that generate electrical signals when the position of the Sun changes, and four other photocells are located in the same way on the inner sides of the screen and form accurate guidance channels, the mentioned additional sensor consists of three cascade-type photocells connected to the azimuth channel, two of which are directed left and right with respect to the main sensor, and the third is opposite opolozhnuyu side, and the polarity of the connection is changed when passing North-South direction, the signal to switch the base frame is supplied from the drive wheel photocells azimuth channel and the signal on the switch actuator is supplied from a suspended frame of photocells zenith channel (see. RF patent No. 2286517 dated 02.21.2005).
The disadvantage of this design is that the drive wheel is used as the executive link, which rotates the installation around the vertical axis, and, therefore, the underlying surface (the surface on which the installation is located) must be strictly smooth, otherwise adequate control signal processing will not be provided executive link. Also, the disadvantage is that the solar battery consists of modules with solar concentrators located in the form of steps, which leads to insufficient protection of the installation from atmospheric precipitation in the form of snow. All this leads to a decrease in the functionality of the installation in the northern latitudes, since the level of precipitation in the form of snow there is quite high.
The purpose of the utility model is to expand the functionality of the installation.
The problem is achieved in that in a known photovoltaic installation containing a solar battery with radiation-receiving photoelectric converters, mounted on a mechanical system supporting the perpendicular position of the solar battery to the direction to the Sun and equipped with a solar battery orientation system to the Sun, the mechanical system includes two executive body - a movable disk, providing the rotation of the installation around a vertical axis, mounted on a fixed base and equipped with an electric drive, and a shaft with a movable platform fixed on it, providing rotation around a horizontal axis from the electric drive, while the solar battery itself consists of modules with photoelectric converters and is equipped with a device for protection from adverse atmospheric influences, and the orientation system contains five light level sensors , which are photoresistors in a housing with a protective screen, mounted on the right, left, top, bottom and rear of the solar panel and form a channel azimuthal and zenithal guidance, generating signals when the position of the sun changes, while the sensor located behind the solar battery measures the level of ambient light and turns the unit at the beginning of a new day, and the signal to turn on the electric drives of the moving disk and shaft is fed from azimuthal and zenithal sensors channels respectively.
The claimed technical solution differs from the prototype in that the supporting mechanical system includes two actuators - a movable disk that provides rotation of the installation around a vertical axis, mounted on a fixed base and equipped with an electric drive, and a shaft with a movable platform mounted on it, providing rotation around a horizontal axis from the electric drive, while the solar battery itself consists of modules with photoelectric converters and is equipped with a device for protection against nebla favorable atmospheric influences, and the orientation system contains five light level sensors, which are photoresistors in a housing with a protective screen, mounted to the right, left, top, bottom and rear of the solar battery and forming azimuth and zenith guidance channels that generate signals when the position of the sun changes at the same time, the sensor located at the rear measures the level of ambient light and turns the unit at the beginning of a new day, and the signal to turn on the electric drives of ska shaft and fed from the zenith and the azimuth sensor channels respectively.
Distinctive features in the claimed technical solution were not identified when studying this and related areas of technology.
The combination of the claimed features ensures the achievement of the task of the utility model - the expansion of functionality.
Figure 1 shows a General view of the proposed device, figure 2 - a device for protection from adverse weather conditions, figure 3 - control system.
The design consists of a fixed base 1, on which the control electronics unit and a movable disk 2 are placed, driven by a horizontal rotation drive 3, two racks 4, a platform with a solar battery 5 mounted on it, driven by a horizontal rotation drive 6, located inside one from the racks. To provide feedback, the device includes two pairs of light level sensors 7 and an additional sensor 8 mounted on the back of the platform, which serves to measure the scattered radiation, eliminate its effect on two other sensors and start the system in the morning. Also in the system there is a microcontroller 9 as a central control device and end sensors 10 to implement a given range of rotation of the executive links. The device for protection against adverse atmospheric influences consists of a solar battery mounted on the platform 11, two movable rollers 12, and a transparent film covering the rollers and having external thickenings in its section. Under the influence of snow accumulating behind the thickenings and thus acting on them with its weight, the transparent film 13 moves with the help of movable rollers 12, passing to the back side of the platform and under the influence of gravity and vibration, clears the snow. Thus, during snowfall, sections of the film continuously replace each other during the operation of the installation.
The photovoltaic installation operates as follows: The signal from a horizontal pair of light level sensors 7 is supplied to the microcontroller 9, which processes it in accordance with the program laid down, determining the difference between the light levels of each sensor, and also comparing this signal with the signal from the additional sensor 8. In the case of a significant difference in the level of illumination, the microcontroller sends a control signal through the driver to the electric drive 3, which drives the movable disk 2. Thus, Guidance in the vertical plane. Moreover, if the shaft of the movable disk 2 reaches one of its limiting positions, the signal from one of the end sensors 10 is supplied to the microcontroller, and the rotation of the disk stops.
Similarly, guidance is carried out in the horizontal plane. The signal from a vertical pair of light level sensors 7 is fed to the microcontroller 9, which processes it in accordance with the program laid down, determining the difference between the light levels of each sensor, and comparing this signal with the signal from the additional sensor 8. In the case of a significant difference in the light level, the microcontroller sends a control signal through the driver to the electric drive 6, which drives the shaft of the mobile platform 5. Moreover, if the shaft of the mobile platform 5 reaches one of its maximum x positions, the microcontroller receives a signal from one of the end sensors 10, respectively, and the rotation of the shaft stops.
The use of this device will simplify the design of the mechanical system, as well as improving its operation in an environment with adverse atmospheric influences
