Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic brackets, and in particular to a method for realizing a novel typhoon-resistant photovoltaic bracket foundation. Background Art

[0002] In recent years, domestic distributed photovoltaic power stations have developed rapidly, and they are mostly distributed in areas with good power consumption, such as urban rooftops and factory buildings. Most of the existing photovoltaic power stations built on urban rooftops and factory buildings have fixed counterweight photovoltaic support foundations, with steel photovoltaic supports on the upper part and cast-in-place concrete foundations on the lower part for compaction.

[0003] In existing rooftop distributed photovoltaic power generation projects, concrete blocks are often used to fix photovoltaic brackets. This method has many defects. In areas with high wind pressure, the weight of the bracket foundation is too large, the amount of concrete pouring is large, and the upper photovoltaic bracket can only be installed after maintenance is completed. The construction period is long and the cost is high. For non-walkable concrete roofs, due to the addition of excessive additional loads, the original structure needs to be reinforced before photovoltaic panels can be laid, which will inevitably cause shutdowns, high reinforcement costs, and poor economic benefits. It is basically not suitable for non-walkable concrete roofs. Summary of the invention

[0004] To solve the above problems, the purpose of the present invention is to provide a new method for realizing a typhoon-resistant photovoltaic support foundation, which can solve the problem of constructing photovoltaic modules on non-walkable roofs without destroying the original structural waterproof layer and without reinforcing the original structure, and meet the typhoon resistance requirements.

[0005] The following scheme is adopted in the embodiment of the present invention to realize: a method for realizing a novel typhoon-resistant photovoltaic support foundation is provided, and the method comprises the following steps:

[0006] Step S1: pouring ground weight blocks on the ground on both sides of the building respectively, pouring multiple photovoltaic bracket foundations on the roof of the building, and reserving a mounting through hole that penetrates the photovoltaic bracket foundation in each photovoltaic bracket foundation; Step S2: arranging pulley devices on both sides of the roof of the building;

[0007] Step S3: fix one end of the steel cable to the ground counterweight on one side, and pass the other end through the pulley device on the same side, the installation through hole, the pulley device on the other side in sequence, and finally anchor downward to the ground counterweight on the other side;

[0008] Step S4: grouting and sealing the installation through holes, and finally installing the photovoltaic modules on the photovoltaic support foundation.

[0009] In one embodiment of the present invention, the building is set on the ground, and the number of the ground counterweight blocks is four, and the four ground counterweight blocks are symmetrically distributed on the ground on the left and right sides of the building; parapets are set around the roof of the building, and two wall holes are opened on the left and right ends of the parapet, and the pulley device is set on the outside of the wall hole. The number of the steel cables is two, one end of the two steel cables is set on the two ground counterweight blocks on the left, and the other end of the steel cable passes through the pulley device on the left, the wall hole on the left, the installation through hole on the same horizontal line, the wall hole on the right and the pulley device on the right in sequence, and the other end of the steel cable is fixed to the ground counterweight block on the right; a plurality of the photovoltaic modules are set on the roof of the building, and each of the photovoltaic modules is set on the basis of four photovoltaic brackets through four supporting feet.

[0010] In one embodiment of the present invention, clamps for fixing the steel cables are symmetrically arranged at the left and right ends of the photovoltaic support foundation.

[0013] Beneficial effects of the invention: The invention provides a novel method for realizing a typhoon-resistant photovoltaic support foundation, which avoids adding counterweights on non-walkable roofs to ensure the stability of photovoltaic modules, reduces the load on non-walkable roofs, reduces reinforcement costs, and is suitable for coastal areas. The upward pulling force generated by typhoons on photovoltaic modules is transmitted to the ground through steel cables and pulley devices, while not damaging the original waterproof layer of the non-walkable roof, reducing the risk of water leakage in the house. The invention has simple construction, short construction period, and reduced reinforcement costs. It can solve the problem of constructing photovoltaic modules on non-walkable roofs without damaging the original structural waterproof layer and without reinforcing the original structure, and meets the typhoon resistance requirements.

[0022] Step S3: fix one end of the steel cable 3 to the ground counterweight block 2 on one side, and the other end passes through the pulley device 4, the installation through hole 7, and the pulley device 4 on the same side in sequence, and finally anchors downward to the ground counterweight block 2 on the other side; the specific implementation method of step S3 is: fix one end of the steel cable 3 to the ground counterweight block 2 on the left side, and the other end passes through the pulley device 4 on the left side upward, and then passes through the wall hole 6 of the parapet 5 on the left side to the right, and then passes through the installation through hole 7 of each photovoltaic bracket foundation 8 on the same horizontal line to the right, and then passes through the wall hole 6 of the parapet 5 on the right side, and finally passes through the pulley device 4 on the right side, and fixes the other end to the ground counterweight block 2 on the right side;
