Photovoltaic single-shaft rotating follow spot device

Abstract

The invention relates to a photovoltaic follow spot device, and in particular relates to a photovoltaic single-shaft rotating follow spot device. The device comprises a main shaft and a photovoltaic board, wherein the main shaft is transversely arranged in the middle part of the photovoltaic board; a spot sensing box is arranged on the spot surface of photovoltaic board through the main shaft; a controller is arranged on the back surface of the photovoltaic board; one end of the main shaft is connected with a plurality of front brackets through a front bearing block, and while the other end of the main shaft is connected with a rear bearing block, wherein the rear bearing block is connected with a plurality of rear brackets through an adjusting plate; the rear bearing block is also connected with the output end of a speed reducer through an universal joint; the input end of the speed reducer is connected with the output end of a driving device; the spot sensing box comprises a light filter, a shading board and a bottom plate, wherein the shading board which is vertical to the bottom plate and free of spot transmission is arranged in the center of the bottom plate; spot sensitive resistors are arranged at two sides of the shading board; the light filter is semispherical; the shading board and the spot sensitive resistors are arranged in the light filter. The device has the characteristics of being simple in structure, free of additional sensor, small in mechanical vibration, and large in follow spot angles.

Description

technical field [0001] The invention relates to a photovoltaic light tracking device, in particular to a photovoltaic single-axis rotating light tracking device. Background technique [0002] The oblique single-axis light tracking device has attracted people's attention due to its many advantages. Up to now, this device has not really entered the public eye. The reasons are as follows: [0003] In the existing single-axis rotary light tracking device, the left and right sides of the bracket must reserve installation positions for mechanical or electronic limit switches, which limits the rotation angle of the main shaft. Different dimensions, seasons, climates, sunlight hours, and durations are different or even uncertain, and fixed-angle brackets do not have universal adaptability. Furthermore, once the limit switch fails or the circuit fails, the bracket itself will be damaged. [0004] The self-locking of the spindle position is done by the electronic brake, which is no...
