Description

Technical Field

[0001] The present invention relates to the field of photovoltaic equipment installation technology, and specifically to a photovoltaic installation sling and a using method thereof. Background Art

[0002] In current green power technologies, photovoltaic power generation is one of the most important technologies.

[0003] To save land, current photovoltaic power stations mostly adopt the combined land use forms of agricultural-photovoltaic complementarity and pastoral-photovoltaic complementarity. The combined land use requires that the photovoltaic modules be at a relatively high distance from the ground, generally more than 2m. This makes the installation and construction of photovoltaic modules become high-altitude operations, with a high risk coefficient and increasingly difficult construction.

[0004] At the same time, the profitability of photovoltaic projects has become weaker due to the parity photovoltaic projects. The resulting cost control has continuously reduced the steel consumption per megawatt of photovoltaic brackets, and further reduced the bearing capacity of photovoltaic brackets. The current construction methods are prone to causing deformation of photovoltaic brackets and increasingly cannot meet the project requirements. Summary of the Invention

[0005] Aiming at the problems existing in the construction of high-bracket photovoltaic modules in the prior art, the present invention provides a photovoltaic installation sling and a using method thereof, which can realize the overall hoisting of the photovoltaic bracket and the module after being assembled on the ground, avoid high-altitude operations, and reduce the construction risk.

[0006] The present invention is realized through the following technical solutions:

[0007] A photovoltaic installation sling includes a driving machine, a photovoltaic sling body, and a hoisting shape-preserving frame. The driving machine is used to drive the photovoltaic sling body to move. The hoisting shape-preserving frame includes an installation frame and multiple groups of parallel support rods. The installation frame is connected to the photovoltaic sling body, and the support rods are connected to the installation frame. The plane formed by the same group of support rods is perpendicular to the plane formed by the installation frame, and the plane formed by the same group of support rods is parallel to the length axis of the installation frame; during use, the top of the support rod is connected to the photovoltaic bracket.

[0008] Preferably, the support rods in different groups have different heights.

[0009] Preferably, the heights of the support rods in different groups gradually decrease along the width axis of the installation frame.

[0010] Preferably, the distance between adjacent two groups of support rods is equal.

[0011] Preferably, the installation frame includes multiple cross bars and multiple vertical bars, and the support rods in the same group are located on the same cross bar.

[0012] Preferably, an installation groove is provided at the top of the support rod, and the installation groove is used for clamping with the photovoltaic bracket.

[0013] Preferably, the driving machine includes a truck crane and a lifting belt. One end of the lifting belt is connected to the truck crane, and the other end is connected to the photovoltaic hoist body.

[0014] Preferably, a lifting interface ring is provided on the photovoltaic hoist body, and the lifting interface ring is connected to the lifting belt.

[0015] A method for using a photovoltaic installation hoist, using the photovoltaic installation hoist, includes the following steps:

[0016] 1) First, connect the photovoltaic bracket to the lifting conforming frame;

[0017] 2) Then, connect the photovoltaic module to the photovoltaic bracket;

[0018] 3) Use the driving machine to hoist the photovoltaic bracket, photovoltaic module and lifting conforming frame as a whole to a predetermined position and fix them in corresponding positions.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] A photovoltaic installation hoist of the present invention can perform conformal installation of the photovoltaic bracket, rapid installation of the photovoltaic module, and overall hoisting of the combination by setting a lifting conforming frame.

[0021] During construction, the method for using a photovoltaic installation hoist of the present invention first assembles the photovoltaic module and the photovoltaic bracket on the ground, and then performs overall hoisting through the photovoltaic installation hoist, which can be quickly installed in place, avoiding construction risks during high-altitude operations, and further reducing the possibility of deformation of the photovoltaic bracket.

Detailed implementation manners

[0027] The following further elaborates on the present invention with reference to specific embodiments, which is an explanation rather than a limitation of the present invention.

[0028] The present invention discloses a photovoltaic installation sling. Referring to Figure 1 , it includes a driving machine, the main body 1 of the photovoltaic sling, and the lifting shape-preserving frame 8. The driving machine is used to drive the main body 1 of the photovoltaic sling to move. The driving machine includes the truck crane 5 and the lifting belt 6. One end of the lifting belt 6 is connected to the truck crane 5, and the other end is connected to the main body 1 of the photovoltaic sling.

[0029] Referring to Figure 2 , a lifting interface ring 7 is provided on the main body 1 of the photovoltaic sling, and the lifting interface ring 7 is connected to the lifting belt 6.

[0030] Referring to Figure 2 , 3 and 4, the lifting shape-preserving frame 8 includes a mounting frame 10 and multiple groups of support rods 9 arranged in parallel. The mounting frame 10 is welded and connected to the main body 1 of the photovoltaic sling.

[0031] The mounting frame 10 includes multiple cross bars 101 and multiple vertical bars 102. In this embodiment, there are four cross bars 101 and twelve vertical bars 102. The cross bars 101 are arranged at intervals, and the vertical bars 102 are welded at intervals between adjacent cross bars 101. The vertical bars 102 are perpendicular to the cross bars 101. The plane formed by the support rods 9 in the same group is perpendicular to the plane formed by the mounting frame 10, and the support rods 9 in the same group are located on the same cross bar 101.

[0032] The support rods 9 are welded to the mounting frame 10, and the plane formed by the support rods 9 in the same group is parallel to the length axis of the mounting frame 10; during use, the top of the support rod 9 is connected to the photovoltaic bracket 3. An installation groove 11 is provided at the top of the support rod 9, and the installation groove 11 is used for snap connection with the cross-section C-shaped steel of the cross arm of the photovoltaic bracket 3.

[0033] The support rods 9 in different groups have different heights, and the heights of the support rods 9 in different groups gradually decrease along the width axis of the mounting frame 10. This is to adapt to the shape of the photovoltaic bracket 3 and facilitate the installation of the photovoltaic bracket 3.

[0034] In order to keep the shape of the photovoltaic bracket 3 intact, the distance between adjacent two groups of support rods 9 is equal, so that the photovoltaic bracket 3 can be evenly stressed on the lifting shape-preserving frame 8, thereby reducing the possibility of deformation of the photovoltaic bracket 3.

[0035] A method for using a photovoltaic installation sling according to the present invention comprises the following steps:

[0036] 1) The photovoltaic bracket 3 can be connected to the hoisting shape-retaining frame 8 by snap-fitting the photovoltaic bracket 3 into the installation groove 11 on the fixed crossbar 101;

[0037] 2) Then, connect the photovoltaic module 2 to the photovoltaic bracket 3;

[0038] 3) Use a driving machine to hoist the photovoltaic bracket 3, the photovoltaic module 2 and the hoisting shape-retaining frame 8 as a whole to a predetermined position, and fix them in the corresponding positions with bolts.

[0039] During the construction of the method for using a photovoltaic installation sling according to the present invention, first assemble the photovoltaic module 2 and the photovoltaic bracket 3 on the ground, and then perform overall hoisting through the photovoltaic installation sling, which can be quickly installed in place, avoiding the construction danger during high-altitude operation, and at the same time further reducing the possibility of deformation of the photovoltaic bracket 3.
