Problems solved by technology

[0005] This device can realize the tracking and positioning of the sun more accurately, but the mechanical structure is relatively complicated, requiring a total of two azimuth drive motors and altitude drive motors, and the cost is correspondingly increased. Not only the power consumption increases, but also the system reliability is reduced.

Abstract

The invention relates to a photovoltaic power generation device with a two-dimensional photovoltaic sun-positioning function. The photovoltaic power generation device comprises a photovoltaic battery plate and a support pillar and also comprises a two-dimensional photovoltaic sun-positioning mechanism, wherein the two-dimensional photovoltaic sun-positioning mechanism contains a first multi-turn element, a second multi-turn element, a connecting piece and a one-dimensional steering unit; the first multi-turn element is arranged on the side edge of the support pillar; the second multi-turn element is arranged on the back of the photovoltaic battery plate; the connecting piece is connected with the steering output ends of the first multi-turn element and the second multi-turn element; the one-dimensional steering unit contains an electric motor and a transmission device; and the electric motor is controlled by a drive unit to realize that the photovoltaic battery plate rotates along with the axial direction of the support pillar.

Description

technical field [0001] The invention relates to a photovoltaic daylighting device, in particular to a two-dimensional mechanism for realizing solar tracking by a photovoltaic panel through a motor. Background technique [0002] As we all know, when the incident angle of sunlight is perpendicular to the photovoltaic panel, the photovoltaic panel generates the most electricity. Therefore, tracking the trajectory of the sun so that the incident angle of sunlight is always perpendicular to the panel will maximize the power generation of the photovoltaic panel. Photovoltaic heliostats currently on the market can be roughly divided into two types in terms of mechanical structure: one-dimensional and two-dimensional. The one-dimensional tracker has a fixed pitch angle (that is, the sun's altitude angle) and only tracks the change of the sun's latitude, usually from east to west every day. For example, a one-dimensional sun tracking device is disclosed in Chinese patent CN20071002...
