Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic panel roof installation, in particular to a non-clamp type photovoltaic panel adapter with a waterproof structure. Background Art

[0002] With the development of roof photovoltaic technology, a large number of photovoltaic modules need to be installed on corrugated steel roofs. The existing steel structure roof panels are of different types. Some corrugated steel roofs can use clamp-type adapters to install roof photovoltaic modules, which will not damage the original building roof waterproofing system. However, a large number of corrugated steel roofs need to use non-clamp-type photovoltaic panel adapters to install photovoltaic modules, which will damage the original building roof waterproofing system. If the waterproofing measures are not appropriate, it will cause water seepage and leakage.

[0003] Chinese patent CN221283099U discloses a photovoltaic panel aluminum alloy bracket, which is arranged on a trapezoidal colored steel tile, characterized in that the aluminum alloy bracket includes three components: a bottom track A, a middle track B and a top track C. The middle track includes two parts: a middle track B1 and a middle track B2. The top track C includes two parts: a top track C1 and a top track C2. The bottom track A and the trapezoidal colored steel tile purlin are placed in parallel. The bottom track A and the trapezoidal colored steel tile purlin are connected and fixed by a colored steel tile clamp J1. The colored steel tile clamp J1 includes two components: a colored steel tile clamp plate and a bottom track connecting plate. The colored steel tile clamp plate is provided with a self-tapping screw hole, and a self-tapping screw is provided on the self-tapping screw hole. The colored steel tile clamp J1 is fixed to the colored steel tile purlin by the self-tapping screw. This structure will have the risk of water seepage and leakage in long-term use, and the overall structure is relatively complex and has poor stability. Summary of the invention

[0004] In order to solve the above problems, the present invention provides a non-clamp type photovoltaic panel adapter with a waterproof structure, which ensures the reliability and stability of the waterproof measures of the non-clamp type photovoltaic panel adapter installed on the corrugated steel plate and reduces the risk of leakage.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a non-clamp type photovoltaic panel adapter with a waterproof structure, including a roof corrugated steel plate, a photovoltaic panel adapter is arranged on the crest of the roof corrugated steel plate, the bottom of the photovoltaic panel adapter is a connecting bottom plate that fits with the crest, a vertically arranged connecting middle plate is arranged above the connecting bottom plate, a horizontally arranged connecting top plate is arranged above the connecting middle plate, a photovoltaic panel connecting hole is arranged on the connecting top plate, a waterproof membrane is arranged between the roof corrugated steel plate and the connecting bottom plate, and the roof corrugated steel plate and the connecting bottom plate are connected by screws.

[0006] An EPDM sealing gasket is arranged between the screw and the connecting bottom plate.

[0007] Neutral silicone sealant is coated on the outside of the screw and the EPDM sealing gasket.

[0008] The connecting screw holes connecting the bottom plate and the roof corrugated steel plate are arranged on the left and right side plates where the wave crest is inclined.

[0009] The photovoltaic panel connection holes on the connection top plate are connected to the photovoltaic panel components.

[0010] The waterproof membrane is a modified butyl rubber self-adhesive fluorocarbon waterproof membrane.

[0011] Beneficial effects of the present invention: Compared with the prior art, the present invention uses a modified butyl self-adhesive fluorocarbon waterproof membrane to waterproof the connecting part of the roof corrugated steel sheet and the photovoltaic panel adapter, installs EPDM sealing washers on the connected screws, and then uses neutral silicone sealant to completely cover the screws and the EPDM sealing washers, thereby greatly improving the waterproof effect; at the same time, the connecting screw holes of the roof corrugated steel sheet and the photovoltaic panel adapter are arranged on the left and right side plates inclined by the crest, rather than on the top of the crest. Since the connecting base plate at the bottom of the photovoltaic panel adapter fits with the crest, compared with the structure connected through the top of the crest, the force is more stable, and the structure of the photovoltaic panel adapter is also simpler. Compared with the prior art, the present invention improves the reliability and stability of long-term use and greatly reduces the risk of leakage. BRIEF DESCRIPTION OF THE DRAWINGS
