Weigh notification number: CN204794826U) and " flexible photovoltaic bracket " (Authorization Notice No.: CN204179992U) etc..However, photovoltaic group
In the case where wind load is especially negative Action of Wind pressure, photovoltaic module can be raised above part, be also easy to produce biggish institutional displacement, light occur
The problems such as lying prostrate component subfissure.
Summary of the invention
The object of the present invention is to provide a kind of prestressing force bilayer suspension cable photovoltaic brackets, can effectively improve flexible photovoltaic bracket
The ability that wind-force is resisted in the case where wind load is especially negative Action of Wind pressure reduces photovoltaic module due to generating biggish institutional displacement
The risk of damage；Its structure simple structure, farmland easy for installation, larger suitable for span, with a varied topography do not influence agricultural machinery work
Industry.
To achieve the above object, the present invention adopts the following technical scheme:
A kind of prestressing force bilayer suspension cable photovoltaic bracket, the rigid support frame of left and right ends, the rigidity are divided into including two
The top of braced frame is equipped with cant beam, and the angle of the cant beam and horizontal plane is A, and the lower section of cant beam is equipped with horizontal beam, is parallel to each other
The first, second lateral load-bearing drag-line be connected between two cant beams, multiple photovoltaic modulies are fixed on side by side by connector
Above described first, second lateral load-bearing drag-line, it is equipped with left side suspension cable in the left side of the rigid support frame of left end, in right end
The right side of rigid support frame is equipped with right side suspension cable, and lateral stability drag-line, the cross are connected between two horizontal beams
It further include the rigid suspended support member of multiple triangles to drag-line is stablized below the middle of the first, second lateral load-bearing drag-line,
Three angles of each rigid suspended support member of the triangle be separately fixed at the first lateral load-bearing drag-line, the second lateral load-bearing drag-line and
On lateral stability drag-line and the rigid suspended support member of each triangle and horizontal plane.
Length adjustment device is equipped on each suspension cable.
Length adjustment dress is equipped on the first lateral load-bearing drag-line, the second lateral load-bearing drag-line and lateral stability drag-line
It sets.
The included angle A is greater than 0 °, is less than or equal to 50 °.
Intermediate support beam is equipped between the left and right rigid support frame, the first lateral load-bearing drag-line and second are laterally held
Weight drag-line is fixed on the support cant beam on intermediate support beam top, and lateral stability drag-line is fixed on the column of intermediate support beam,
The support cant beam is parallel with cant beam.
Compared with prior art the beneficial effects of the present invention are: due to the adoption of the above technical scheme, in two horizontal beams
Between be connected with lateral stability drag-line, the lateral stability drag-line is located at below the middle of the first, second lateral load-bearing drag-line,
Three angles of multiple rigid suspended support members of the triangle are separately fixed at the first lateral load-bearing drag-line, the second lateral load-bearing drag-line
With on lateral stability drag-line and the rigid suspended support member of each triangle and horizontal plane, this structure, when strong wind forms positive pressure
When, the lateral load-bearing drag-line of first, second tightened can effectively prevent wind pressure from elapsing photovoltaic module downwards, when strong wind is formed
When negative pressure, the lateral stability drag-line tightened can effectively prevent wind pressure that photovoltaic module is upward by the rigid suspended support member of triangle
Passage improves the ability that flexible photovoltaic bracket resists wind-force in the case where wind load is especially negative Action of Wind pressure, reduces photovoltaic module
The risk damaged because generating biggish institutional displacement；Structure of the invention simple structure, it is easy for installation, it is multiple to be applicable to landform
Miscellaneous, span needs greatly, under photovoltaic module the place in larger agricultural machinery working space.
