Embodiment 1

[0019] Example 1 as figure 1 Shown: a photovoltaic power generation device with two axes automatically tracking the sun controlled by an electric push rod, including a solar panel 8, a transmission mechanism for controlling the rotation of the solar panel, and it also includes a bracket 28, a connecting frame 29, a transverse shaft 13 and the longitudinal axis 14; the support 28 includes a base 30, a support column 5 and a crossbeam 10, the support column 5 is installed on the base 30, the crossbeam 10 is installed on the support column 5, and the connecting frame 29 is connected with the solar panel 8 through the transverse axis 13, and connected The lower part of the frame 29 is looped on the longitudinal axis 14, and the longitudinal axis 14 is fixed on the top of the support column 5; the transmission mechanism includes the height angle electric telescopic push rod 1 and the hour angle electric telescopic push rod 2; the lower bearing 4 is installed at the bottom of the sup...

Embodiment 2

[0031] Example 2 figure 2 Shown is the second embodiment of the present invention, the crossbeam 10 is fixed with a vertical shaft 33, and one end of the hour angle electric telescopic push rod 2 is connected to the crossbeam 10 through the vertical shaft 33; the lower bearing 4 is equipped with a longitudinal shaft 21, and the hour angle The other end of the electric telescopic push rod 2 is connected with the longitudinal rotating shaft 21 . All the other structures are the same as in Example 1.

[0032] The hour angle electric telescopic push rod 2 telescopically pushes the lower bearing 4 to rotate, and drives the height angle electric telescopic push rod 1 fixed on the lower bearing 4 to rotate. Because the upper end of the height angle electric telescopic push rod 1 is connected to the solar panel 8, the solar panel is driven 8 rotates left and right, that is, it drives the solar panel 8 to rotate around the vertical axis 14 to track the solar hour angle.

Embodiment 3

[0033] Example 3 image 3 Shown is the third embodiment of the present invention, the slider 6 is fixed on the upper end of the slide rod 7, the support column 5 is equipped with the upper bearing 3 and the lower bearing 4, the height angle electric telescopic push rod 1 is fixedly connected to the lower bearing 4, and the lower bearing 4 is fixed on the lower bearing 4. Bearing 4 is equipped with longitudinal rotating shaft 21 and horizontal rotating shaft 22, and crossbeam 10 is fixedly provided with vertical shaft 33, and one end of hour angle electric telescopic push rod 2 is connected to crossbeam 10 through vertical shaft 33, and the other end is connected with longitudinal rotating shaft 21; Telescopic push rod 1 is not associated with upper bearing 3. All the other structures are the same as in Example 1.

[0034] Since the upper bearing 3 has no constraints on the height-angle electric telescopic push rod 1, the connection between the lower end of the electric push r...

Abstract

The invention relates to an electric push rod-controlled photovoltaic generating set for automatically tracking the sun with double shafts, which comprises a solar panel, a bracket, a connecting frame, a transverse shaft and a longitudinal shaft, wherein the bracket comprises a base, a bracket column and a beam; the bracket column is installed on the base; the beam is installed on the bracket column; the connecting frame is connected with the solar panel through the transverse shaft; the lower part of the connecting frame is flexibly sleeved on the longitudinal shaft which is fixedly arranged on the top end of the bracket column; a transmission mechanism comprises an elevating angle electric telescopic push rod and an hour angle electric telescopic push rod; the lower end of the elevating angle electric telescopic push rod is connected to the bracket column through a lower bearing; the upper end of the elevating angle electric telescopic push rod is connected to the solar panel through a slide block and a slide rod and is used for controlling the solar panel to rotate around the transverse shaft; and the hour angle electric telescopic push rod is used for controlling the solar panel to rotate around the longitudinal shaft. The photovoltaic generating set has a simple structure; the transmission mechanism is controlled at low power consumption; the hour angle tracking range is larger than or equal to + / -50 degrees; the elevating angle change range is larger than or equal to + / -35 degrees; and the generating efficiency of the solar panel is largely increased.

Description

technical field [0001] The invention belongs to the technical field of solar energy applications, and relates to a photovoltaic power generation device that automatically tracks the sun, specifically a dual-axis photovoltaic power generation device that automatically tracks the sun controlled by an electric push rod. Background technique [0002] Solar photovoltaic power generation provides sustainable energy for human beings and protects the environment on which they depend, but its low power generation efficiency and relatively high power generation cost are still important factors restricting its large-scale application. Before the emergence of high-efficiency photovoltaic cell materials, the development of a practical solar photovoltaic power generation automatic tracking system is one of the main ways to improve the efficiency of solar photovoltaic power generation and promote the application of solar energy. [0003] Foreign countries have done a lot of research on sol...
