[0002] BIPV, i.e., building integrated photovoltaic, is a common form of photovoltaic power generation. There are various ways for roof water guide grooves. Generally, the water guide groove needs to be installed and fixed by screws passing through the middle of the water guide groove. For example, the waterproof photovoltaic roof fixing structure of a three-channel water groove disclosed in the publication number CN219638255U. Rainwater may seep into the interior along the screw holes, causing roof leakage and rusting of the steel structure.

[0003] Therefore, there is an urgent need for a roof waterproof structure that can effectively prevent rainwater from leaking along the screw holes. Summary of the Utility Model

By setting the sleeve, the deformation of the water guide groove during installation is avoided, and it is not necessary for the edge of the water guide groove to extend down to the top surface of the roof purlin completely, saving the material of the water guide groove.

[0011] Further preferably, an aluminum alloy waterproof cover plate is arranged above the pressing block. It covers the gap between the photovoltaic modules, so that as much rainwater as possible is drained from the upper part of the roof components.

[0012] Further preferably, the top surface of the fixing bolt is not higher than the top surface of the water guiding groove, ensuring that the photovoltaic module can be placed flat on the upper part of the water guiding groove.

[0013] Further preferably, the chute portion includes a square frame structure with an upper opening, and both sides of the opening of the square frame structure are respectively connected to vertically arranged plates arranged side by side;

[0014] The screw of the T-shaped bolt slides between the vertically arranged plates arranged side by side.

[0015] Further preferably, a horizontally supporting portion and a water trough portion are sequentially arranged between the chute portion and the concave bending portion and are connected in sequence;

[0016] The rubber strip is clamped between the horizontally supporting portion and the frame of the photovoltaic module;

[0017] The bottom of the water trough portion overlaps above the purlin.

[0018] Further preferably, the concave bending portion is wider at the top and narrower at the bottom.

[0019] It is convenient for the fixing bolt to pass through.

[0020] The technical effect of the present utility model is as follows:

[0021] 1. The pressing block is matched with the T-shaped bolt and is fixed by the chute portion inside the water guiding groove. The pressing block is fixed without using screws to penetrate the water guiding groove, completely avoiding the possibility of rainwater leaking through the screw holes in the middle of the water guiding groove.

[0022] 2. By setting the sleeve, the deformation of the water guiding groove during installation is avoided, and it is not necessary for the edge of the water guiding groove to extend down completely to the top surface of the roof purlin, saving the material of the water guiding groove.
