Description

A photovoltaic energy storage intelligent integrated machine

Technical Field

The invention relates to the field of photovoltaic energy storage technology, and specifically refers to an intelligent all-in-one photovoltaic energy storage machine.

Background Art

With the cost reduction and popularization of energy storage technology, energy storage has become an important auxiliary tool for new energy. The form of photovoltaics plus energy storage will become an important form of photovoltaic utilization in the future. Photovoltaic energy storage panels absorb sunlight and convert solar radiation energy directly or indirectly into electrical energy through photoelectric effect or photochemical effect, and store electrical energy through intelligent control, integrating photovoltaic inverters, batteries and controllers inside.

However, during the installation process of existing photovoltaic energy storage intelligent integrated machines, a fixed pitch angle is generally selected and then fixed. If adjustment is needed later, the process is more complicated and not conducive to rapid adjustment under different lighting conditions, which in turn affects the conversion effect of sunlight. At the same time, it is also inconvenient to clean the dust adhering to the light-receiving surface.

The invention is further described in detail below in conjunction with the full text.

As shown in Figures 1 to 4, a photovoltaic energy storage intelligent integrated machine includes a bracket 2, on which a solar direction angle tracking structure 1 is installed. The present invention can automatically adjust the position of the photovoltaic panel 5 according to the rising and setting of the sun through the solar direction angle tracking structure 1, so that the photovoltaic panel 5 is always facing the sunlight, and the photovoltaic panel 5 can fully convert light energy into electrical energy.

The present invention is specifically implemented as shown in FIG4. The present invention includes a photovoltaic panel 5, a solar cell assembly, a controller and a battery pack 8. If an AC load is to be powered, an AC inverter is also required. Specifically, the basic principle of the photovoltaic panel 5 is to directly convert solar energy into electrical energy using the photovoltaic effect of a solar cell (in fact, a solar cell is a semiconductor device similar to a crystal diode). When a photon irradiates a metal, its energy can be completely absorbed by an electron in the metal. The energy absorbed by the electron is large enough to overcome the Coulomb force inside the metal atom to do work, escape from the metal surface, and become a photoelectron.

In a specific implementation of the present invention, as shown in FIGS. 1 to 3 , the solar azimuth tracking structure 1 includes a crossbar 101 and a connecting plate 103. The middle portion of the crossbar 101 is hinged to the upper end of the bracket 2. A vertical bar 102 is installed on one side of the crossbar 101. The connecting plate 103 is hinged to both sides of the upper end of the crossbar 101. An end of the vertical bar 102 away from the crossbar 101 and the connecting plate 103 are hinged with a first telescopic rod 104. A side of the bracket 2 and a side of the crossbar 101 away from the vertical bar 102 are hinged with a second telescopic rod 105. A connecting frame 9 is relatively installed at the lower end of the connecting plate 103. The crossbar 101 is hinged on the two connecting frames 9. The telescopic end of a telescopic rod 104 is hinged on one of the connecting frames 9, and the other end is hinged on the vertical rod 102. The telescopic end of the second telescopic rod 105 is hinged on the cross bar 101, and the other end is hinged on the bracket 2. When the first telescopic rod 104 is extended, the X-axis position is adjusted to push the connecting plate 103 to rotate on the hinged cross bar 101. At the same time, the other end of the first telescopic rod 104 is hinged on the vertical rod 102, which can realize automatic adjustment to prevent jamming. At the same time, the Y-axis position can be adjusted according to the extension of the second telescopic rod 105, and the cross bar 101 can be adjusted to rotate on the bracket 2, thereby adjusting the position of the connecting plate 103.

Because the sun does not rise and set in different directions, in winter, the sun rises in the east-south direction and sets in the west-south direction; in summer, the sun rises and sets in the east-north direction and west-north direction respectively. In places with different latitudes, the degree of "tilt" of the sun's trajectory is also different. The two points where the celestial equator intersects the horizon are due east and due west. The sun rises in the east-north direction on the summer solstice and sets in the west-north direction. When the sun is at mid-heaven on the summer solstice, that is, when the local time is noon, the sun in the area south of the Tropic of Cancer is in the north of the zenith, and the sun in the area north of the Tropic of Cancer is in the south of the zenith. The solar direction angle tracking structure 1 of the present invention can adjust the position of the connecting plate 103 according to the extension of the first telescopic rod 104 and the second telescopic rod 105, so that the connecting plate 103 always follows the rising and setting of the sun, and can fully convert light energy into electrical energy through the photovoltaic panel 5.

During the specific implementation of the present invention, as shown in FIGS. 1 and 2 , a driving motor 3 is fixedly connected to the connecting plate 103, a rotating shaft 4 is installed at the rotating end of the driving motor 3, a rotatable stacked photovoltaic panel 5 is installed on the outer side of the rotating shaft 4, and the plurality of photovoltaic panels 5 include an active rotating photovoltaic panel 501 fixedly connected to the upper end of the rotating shaft 4 and a plurality of groups of driven rotating photovoltaic panels 502 connected to the outer side of the rotating shaft 4 by bearings, a circular frame 301 is installed on the outer side of the rotating shaft 4 and fixedly connected to the driving motor 3, a fixed photovoltaic panel 503 is fixedly installed on the circular frame 301, a lever is installed at the lower end of the active rotating photovoltaic panel 501 and the driven rotating photovoltaic panel 502, and an active groove 504 used in conjunction with the lever is provided on the upper end surface of the fixed photovoltaic panel 503 and the driven rotating photovoltaic panel 502, and the driving motor 3 works , the rotating shaft 4 rotates, driving the active rotating photovoltaic panel 501 to rotate, and the active rotating photovoltaic panel 501 rotates and moves in the active groove 504 of the driven rotating photovoltaic panel 502 of the lower layer through the lever, and the guide lever can drive the driven rotating photovoltaic panel 502 to rotate on the side wall of the active groove 504, and similarly drive the driven rotating photovoltaic panel 502 of the lower layer to rotate, and then open them in sequence, as shown in Figure 1. In a specific implementation, a torsion spring is also provided between the driven rotating photovoltaic panel 502 and the rotating shaft 4. When rotating to open, the torsion spring is in a working state, which will ensure that the photovoltaic panels 5 are firmly arranged together when opened. When folded, the rotating shaft 4 direction of the driving motor 3 rotates, and the torsion spring is reset at the same time, and the active rotating photovoltaic panel 501 and the driven rotating photovoltaic panel 502 are rotated and folded, as shown in Figure 2.

In a specific implementation of the present invention, as shown in FIG2 , an automatic cleaning device 6 is installed between multiple photovoltaic panels 5, and the automatic cleaning device 6 includes a cleaning plate 601 arranged at the lower ends of the driven rotating photovoltaic panel 502 and the active rotating photovoltaic panel 501, and a cleaning brush 602 is installed on the cleaning plate 601. When the active rotating photovoltaic panel 501 and the driven rotating photovoltaic panel rotate, the cleaning brush 602 is driven to clean the photovoltaic panel on the lower layer. Compared with the prior art, the device can help the user to directly clean the photovoltaic panel 5, and can be cleaned again when it is folded up, completing two cleanings. When the prior art is used, the cleaning process is more cumbersome and the use of tools is more inconvenient.

Working principle of the invention:

First, the driving motor 3 works, the rotating shaft 4 rotates, and the active rotating photovoltaic panel 501 is driven to rotate. The active rotating photovoltaic panel 501 is rotated and moved in the active groove 504 of the driven rotating photovoltaic panel 502 of the lower layer through the lever. The guide lever can drive the driven rotating photovoltaic panel 502 to rotate on the side wall of the active groove 504. Similarly, it drives the driven rotating photovoltaic panel 502 of the lower layer to rotate, and then opens in sequence. According to the different positions of the rising and falling of the sun, when the first telescopic rod 104 is extended, the X-axis position is adjusted to push the connecting plate 103 to rotate at an angle on the hinged cross bar 101. At the same time, the other end of the first telescopic rod 104 is hinged on the vertical rod 102, which can realize automatic adjustment to prevent jamming. At the same time, the second telescopic rod 105 can be extended to adjust the Y-axis position, and the adjustable cross bar 101 can be rotated on the bracket 2, thereby adjusting the position of the connecting plate 103, so that the photovoltaic panel 5 always follows the rising and setting of the sun, and can fully convert light energy into electrical energy through the photovoltaic panel 5.

The photovoltaic energy storage intelligent integrated machine of the present invention can increase the annual power generation by about 20%. It will automatically clean the photovoltaic panels before and after work, ensuring that the generator can remain clean during daily operation. This is 6% more efficient than the photovoltaic panels covered with dust on the roof.

The invention and its implementation methods are described above, which is not restrictive. What is shown in the full text is only one of the implementation methods of the invention, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention, they should all fall within the scope of protection of the invention.
