A self-adjusting photovoltaic module bracket and its adjustment method

Abstract

The invention provides a self-adjusting photovoltaic module bracket and an adjusting method thereof. The self-adjusting photovoltaic module bracket comprises a bracket upright post, a bracket girder, a counterweight structure, a power water tank and a flow control valve, wherein the bracket girder is connected with the bracket upright post and can rotate in the axial direction; the bracket girder is provided with an extension bracket which extends outwards; the counterweight structure is arranged on the extension bracket, so that the gravity center of the extension bracket does not coincide with that of the bracket girder; the power water tank is arranged at one side of the extension bracket through a hanging rod; a drainage pipeline is arranged at one end of the power water tank; the flow control valve is arranged on the drainage pipeline, and controls the power water tank to quantitatively drain away water; the weight of the drainage pipeline linearly changes along with time; and the extension bracket rotates to a corresponding inclination angle at which the torque balance of the extension bracket can be achieved along with the weight change of the power water tank. The control mode is discharged water flow control; the control difficulty is relatively low; and relatively high tracking accuracy can be achieved.

Description

technical field [0001] The invention relates to the technical field of solar photovoltaic modules, in particular to a self-adjusting photovoltaic module bracket and an adjustment method thereof. Background technique [0002] Existing solar photovoltaic module brackets generally include ordinary fixed brackets and adjustable brackets capable of adjusting the angle of the photovoltaic module. Generally, in order to effectively improve the power generation efficiency of photovoltaic modules and adapt to changes in the angle of sunlight, solar trackers with adjustable brackets (to maintain the vertical angle between photovoltaic modules and sunlight) have begun to be widely used. [0003] And the power drive scheme of existing solar tracker support mainly adopts the mode that motor drives support to rotate. The motor drive generally includes two drive forms: the first type drives the electric push rod through the motor to achieve a large thrust, thereby driving the rotation of ...
