Description

Technical Field

[0001] The utility model relates to a photovoltaic module, in particular to an assembly and support structure of a lightweight photovoltaic module. Background Art

[0002] Roof-mounted photovoltaic module power generation is a new energy power generation method; the photovoltaic module frame is arranged on the roof through a support base, and the support base is connected to the roof through riveting bolts; when installing the riveting bolts, it is necessary to drill holes in the roof structural layer, then pour chemical agents into the holes, insert the planted bolts into the chemical agents in the holes, and after the agents solidify, connect the support base of the photovoltaic module frame to the planted bolts; therefore, when installing the support base of the roof-mounted photovoltaic module, it is first necessary to drill holes in the roof structural layer, and then inject chemical agents into the holes. Before injecting the chemical agents, it is necessary to blow the concrete powder and fine sand grains remaining in the bolt holes, on the hole walls, and in the base foundation pit area to ensure that the chemical agents are firmly bonded to the original concrete structure, thereby ensuring the reliability of the bolts; if the dust powder in the drilled holes is not cleaned up, voids will appear at the joint between the chemical agent and the hole, forming a potential hazard of water leakage; affected by the concrete powder and fine sand grains, the implanted bolts will not be firmly bonded to the holes, and cannot withstand the external force during the installation process, resulting in delamination and displacement; in addition, due to the presence of concrete powder and fine sand grains in the holes, the depth of the bolts implanted into the holes also fails to meet the design requirements, thereby reducing the bearing capacity and durability of the base, affecting the safety and normal operation of the photovoltaic module; currently, the blowing method used on site is to blow with a large-diameter air duct of a hair dryer, which has the problem of incomplete blowing in the planted holes, directly leading to problems such as easy loosening, offset of the implanted bolts, and insufficient bonding force between the chemical agent and the holes. Summary of the Invention

[0003] The utility model provides a blowing device for implanted bolt holes for fixing the support base of a roof-mounted photovoltaic module, which solves the technical problem of incomplete blowing in the planted holes existing in the prior art.

[0004] The utility model solves the above technical problems through the following technical solutions:
