Detailed Description

The following description of the embodiments of the present invention will be made with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

Supporting rod

The branch is as the base of photovoltaic unit, but direct fixed connection is on fixed support, perhaps further, and branch and mobile jib and diagonal brace are connected, and branch, mobile jib and diagonal brace make up into triangular connecting rod structure, are provided with a plurality of branches around the mobile jib, form the structure that opens and shuts of similar umbelliform.

The branch quantity of mobile jib periphery is according to the size of photovoltaic plate and the angle of opening and shutting of branch and synthesize and confirm. The adjacent light receiving surfaces or the fitting of the photovoltaic panels depend on the thickness of the photovoltaic panels and the size of the brackets and the supporting rods.

Photovoltaic panel unit

The photovoltaic panels in the photovoltaic panel units on both sides of the strut can be shaped like photovoltaic panels of different shapes. Based on the photovoltaic panels of the same shape, the number of photovoltaic panels located on both sides of the strut may vary. Preferably, the photovoltaic panels on both sides of the strut are symmetrically arranged. The outer edges of the two symmetrical photovoltaic panels are flush in the folded state, the frame interval of the photovoltaic assembly is small, and the amount of wind sand entering between the two folded photovoltaic panels in the wind sand environment is small.

Photic state and folding state of photovoltaic panel

The light receiving state of the photovoltaic panel refers to a state in which the photovoltaic panel faces the light source, i.e., the panel in the photovoltaic panel faces upward. Under the light receiving state, the included angle of the light receiving sides of the two photovoltaic panels connected with the same supporting rod is equal to, larger than or smaller than 180 degrees, and preferably equal to or larger than 180 degrees. The folding state needs to satisfy the following three conditions simultaneously: the photovoltaic panel is arranged along the vertical direction, the photovoltaic panel is positioned at the light receiving side of the supporting rod, and the light receiving surfaces of the photovoltaic panels at the two sides of the supporting rod are adjacent or attached to each other. The smaller the distance between the light receiving surfaces of the two photovoltaic panels connected with the same supporting rod is, the better the protection effect on the photovoltaic panels is.

Rotary connection and locking piece of bracket and support rod

The rotational connection of the bracket to the strut includes known rotational connections and is not limited to a shaft and a bushing. The locking member functions to fix the relative positions of the bracket and the strut. Specifically, a gear or a worm wheel is arranged on a rotating shaft of the rotating structure, and the locking piece comprises a gear clutch and a worm which correspond to each other, so that the aim of locking the bracket and the support rod can be achieved.

Rotating shaft and shaft sleeve

The positions of the rotating shaft and the shaft sleeve can be interchanged, namely, the rotating shaft is arranged on the cantilever, the shaft sleeve is arranged on the bracket, or the shaft sleeve is arranged on the cantilever, and the rotating shaft is arranged on the bracket. The axial of pivot is unanimous with the axial of branch to and the photovoltaic unit symmetry setting of branch both sides all helps guaranteeing that branch and photovoltaic unit's assembly body center is located directly over the branch. Compared with the center of the photovoltaic panel in a folded state deviating from the support rod, the connection structure of the photovoltaic module is more stable and reliable, and the service life of the photovoltaic module is prolonged.

First stopper and second stopper

The two first limiting blocks limit the stroke of the second limiting block, and specifically, the central angle of the stroke of the second limiting block is 80-100 degrees.

First articulated seat, second articulated seat and third articulated seat

The first hinge seats are connected with the end parts of the supporting rods, the inclined supporting rods, the supporting rods and the main rod form a triangular connecting rod structure, and the end parts of the inclined supporting rods are switched between the two hinge seats to realize the unfolding and folding of the supporting rods. Equivalent alternative structures include, but are not limited to, known umbrella frame structures: the lantern ring is arranged outside the main rod and is in pin joint with the diagonal brace, and the lantern ring moves along the main rod to drive the branch rods to be unfolded and folded.

Furthermore, in order to optimize the hail impact protection effect, the frame of the photovoltaic panel can be locally enhanced, or a buffer layer can be arranged in and/or outside the top frame of the photovoltaic panel.
