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 connected to the front end of the next purlin guided 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. No matter how much the distance between each row is, the length difference of each section of cable can be adjusted to keep each row of battery panels rotating synchronously at the same angl...

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 A9 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 cables are respectively connected to the two ends of the transmission chain 4. 5. The other ends of the two traction cables 5 are respectively guided throug...

Abstract

The invention provides a flexible driving apparatus for an all-terrain-matched linkage tracking photovoltaic bracket. The flexible driving apparatus comprises a reduction gear chain wheel, stand columns for supporting and rotating solar cell panels, and main beams moving on the corresponding stand columns, wherein purlines are arranged on the main beams for realizing power transmission for each row of solar cell panel array; the tail end of a former purline is connected with the front end of a next purline through a synchronous cable rope by a pulley A in a guiding connection manner so as to realize the series connection of the heads and the tails of the purlines; the reduction gear chain wheel drives a transmission chain to move in a reciprocating manner; two dragging cable ropes are connected with the two ends of the transmission chain respectively; the other ends of the two dragging cable ropes are connected with the synchronous cable rope through two pulleys B; and each of the two pulleys B is connected with a balance weight part separately for keeping the automatic compensation tensioning force of the transmission chain and the dragging cable ropes. The flexible driving apparatus is simple in structure, easy to mount, and capable of solving the problems of high requirement on land leveling standard and impossibility of being mounted and used in barren mountains and steep slopes with quite severe terrains.

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...
