Embodiment 1

[0021] Such as figure 1 The shown all-terrain matching linkage tracking photovoltaic support flexible drive device includes a reducer sprocket 3, a column 12 for supporting and rotating solar panels, and a main beam 8 that can move on the column. There are purlins 1, which are used to transmit power in each row of solar panel arrays. The purlins 1 are hinged on the main beam 8 through bolts, and the synchronous cables 2 are pulled, so that the purlins 1 rotate synchronously. The tail end of the purlin is guided and connected to the front end of the next purlin by the pulley A9 through the synchronous cable 2 to realize the end-to-end series connection of the purlins. Specifically, the purlins on the N rows of battery panel supports are connected in series by N+1 sections of synchronous cables. The effect is that regardless of the distance between each row, the length difference of each section of the cable can be adjusted to keep each row of battery panels rotating synchronous...

Embodiment 2

[0024] Such as figure 2 As shown, the basic principle and structure of Example 2 are the same as Example 1. The column 12 can also be installed on the concrete pipe pile 11. When the concrete pipe pile 11 is used for installation, the counterweight 6 is suspended on the concrete pipe pile 11. .

Embodiment 3

[0026] Such as image 3 Shown is a schematic diagram of the structure of the present invention matched on the complex terrain of the mountain, all-terrain matching linkage tracking photovoltaic support flexible drive device, reducer sprocket 3 and column 12 for supporting and rotating solar panels, and can move on the column The main beam 8 is provided with purlins 1 on the main beam 8, which are used to transmit power in each row of solar panel arrays. Between the purlins 1, the tail end of the previous purlin is passed through the synchronous cable 2 according to the needs of the terrain. Multiple sets of pulleys A 9 guide and connect to the front end of the next purlin to realize the end-to-end series connection of the purlins. The sprocket 3 of the reducer drives the transmission chain 4 to reciprocate, and two traction chains are respectively connected to the two ends of the transmission chain 4. Cable 5, the other ends of the two traction cables 5 are respectively guided...

Abstract

Provided in the present invention is a flexible driving device for an all-terrain-matching linkage tracking photovoltaic support, comprising: a reducer sprocket, columns for supporting and rotating solar panels, and main beams that are movable on the columns. The main beams are provided thereon with purlins for transferring power to respective arrays of solar panels, the rear end of a preceding purlin being connected, by means of a synchronous cable guided by a pulley A, to the front end of a following purlin, realizing a head-to-tail serial connection of the purlins. The reducer sprocket drives a transmission chain in a reciprocating motion, two traction cables being respectively connected to the two ends of the transmission chain, and the other end of the two traction cables being connected to synchronous cables via two pulleys B. The two pulleys B each are fitted with a counterweight to maintain an automatically compensated tensile force of the transmission chain and the traction cables. The present invention is structurally simple and easy to install, solving the problem that a linkage horizontal single-axis, linkage inclined single-axis, or linkage array-type double-axis tracking support has to meet a high standard concerning the flatness of the land and cannot be installed and used on a barren mountain or a steep slope with complex terrain.

Description

technical field [0001] The invention relates to the field of photovoltaic supports, in particular to an all-terrain matching linkage tracking photovoltaic support flexible drive device. Background technique [0002] Since the 1980s, various forms of tracking solar power generation systems developed by countries around the world have been widely used in photovoltaic power plants of various sizes. Among them, the most widely used is the linkage tracking bracket, which is the most direct, simple, reliable, low-cost and most effective method to improve the power generation efficiency of solar cells. [0003] At present, the driving devices of linkage tracking brackets at home and abroad all use rigid kinematic pairs, such as electric reducer (or electric push rod) + main push rod + multiple rows of solar panels to drive the push rod together; Electric reducer + multiple drive shafts with universal joints in series + multiple worm gear reducers + multiple rows of solar panels li...
