[0003] At present, with the society's emphasis on new energy, BIPV has been widely used. However, the existing BIPV roof drainage system has an unsightly external gutter design and no structural waterproof design. In actual use and installation, other blocking measures must be used to avoid leakage and backflow problems. In addition, the exposed gutter has water accumulation at the bottom when overlapped, and the accumulation of rainwater can easily damage photovoltaic modules. Summary of the invention

[0006] An assembled waterproof photovoltaic integrated roof is formed by splicing a plurality of photovoltaic unit modules arranged in a matrix, each photovoltaic unit module is a U-shaped plate structure with a U-shaped notch facing backwards, a strip-shaped water guide groove penetrating the top and bottom of the photovoltaic unit module is provided on the front end surface of the right parallel part of the photovoltaic unit module, an upper slot and a lower slot are provided on the right parallel part of the photovoltaic unit module and on the side of the strip-shaped water guide groove, the upper slot is adjacent to the top of the photovoltaic unit module and the notch faces upwards, and the lower slot is provided at the bottom of the photovoltaic unit module and the notch faces downwards;

[0007] The front of the photovoltaic unit module is a two-step stepped surface, that is, a first step surface facing upward is formed between the middle and the bottom of the photovoltaic unit module, and a second step surface facing upward is formed between the middle and the top. A row of screw locking holes that pass through from front to back are arranged on the top of the photovoltaic unit module. A cell embedded groove is arranged in the middle of the photovoltaic unit module, and the photovoltaic cell is embedded in the cell embedded groove. The left side of the photovoltaic unit module and the left groove surface of the strip water guide groove are both first-step stepped surfaces. The step surface on the left side of the photovoltaic unit module and the step surface on the left side of the strip water guide groove are both facing upward and have the same height, and both are lower than the horizontal height of the second step surface.

[0008] The right groove surface of the strip-shaped water guide groove is also a stepped surface, and the step surface on the right side of the strip-shaped water guide groove faces upward, so that the width of the notch at the top of the strip-shaped water guide groove is not less than the width of the bottom end of the parallel portion on the right side of the photovoltaic unit module;

[0009] When two longitudinally adjacent photovoltaic unit modules are vertically spliced, the bottom of the upper photovoltaic unit module completely covers the top of the lower photovoltaic unit module, the right parallel portion of the upper photovoltaic unit module partially extends into the strip water guide groove of the lower photovoltaic unit module, the portion between the upper slot and the strip water guide groove of the lower photovoltaic unit module is inserted into the lower slot of the upper photovoltaic unit module with a clearance fit, and the portion of the upper photovoltaic unit module located on the left side of the lower slot is inserted into the upper slot of the lower photovoltaic unit module with a clearance fit;

[0010] When two laterally adjacent photovoltaic unit modules are spliced, the left parallel portion of the right photovoltaic unit module extends into the strip water guide groove of the left photovoltaic unit module, and the left parallel portion of the left photovoltaic unit module is adjacent to the left groove wall of the strip water guide groove of the right photovoltaic unit module, so that the right photovoltaic unit module covers the notch of the strip water guide groove of the left photovoltaic unit module.

[0011] When the two longitudinally adjacent photovoltaic unit modules are vertically spliced, the level of the top of the lower photovoltaic unit module is lower than the level of the bottom of the lower slot of the upper photovoltaic unit module.

[0012] The horizontal height of the bottom end of the upper slot is lower than the horizontal height of the left step surface of the strip water guide groove, and the bottom end of the upper slot is connected with the inside of the strip water guide groove through the opening on the left groove surface of the strip water guide groove.

[0013] When the two longitudinally adjacent photovoltaic unit modules are vertically spliced, the outer side surface of the right parallel portion of the upper photovoltaic unit module is in close contact with the right groove surface of the strip-shaped water guide groove of the lower photovoltaic unit module.

[0014] Advantages of the present invention:

[0015] (1) The photovoltaic unit module of the present invention is a U-shaped plate structure with the U-shaped notch facing backwards, and a strip water guide groove with the notch facing forward is arranged on the parallel portion on the right side of the photovoltaic unit module. When two laterally adjacent photovoltaic unit modules are spliced, the left parallel portion of the right photovoltaic unit module and the strip water guide groove of the left photovoltaic unit module are handshake-style docked, so that the right photovoltaic unit module covers the notch of the strip water guide groove of the left photovoltaic unit module, so that the strip water guide groove is hidden, which is beautiful and neat.

[0016] (2) The front side of the photovoltaic unit module of the present invention is a two-step stepped surface, so that when two longitudinally adjacent photovoltaic unit modules are vertically spliced, the bottom of the upper photovoltaic unit module is completely covered on the top of the lower photovoltaic unit module, thereby blocking a row of screw locking holes on the top of the lower photovoltaic unit module, avoiding the problem of water leakage from the screw locking holes, and the right parallel portion of the upper photovoltaic unit module partially extends into the strip water guide groove of the lower photovoltaic unit module, so that the joints of the strip water guide grooves of the upper and lower photovoltaic unit modules partially overlap, achieving a tight overlap of the strip water guide grooves in the longitudinal direction.

[0017] (3) The present invention sets an upper slot and a lower slot on the right parallel part of the photovoltaic unit module. When two longitudinally adjacent photovoltaic unit modules are vertically spliced, the lower slot of the upper photovoltaic unit module and the upper slot of the lower photovoltaic unit module are plugged into each other, thereby realizing accurate positioning and plugging of the two longitudinally adjacent photovoltaic unit modules.

[0018] (4) In the present invention, when two laterally adjacent photovoltaic unit modules are spliced, the left parallel portion of the left photovoltaic unit module is adjacent to the left groove wall of the strip water guide groove of the right photovoltaic unit module, and a small gap flow channel is formed between the left parallel portion of the left photovoltaic unit module and the left groove wall of the strip water guide groove of the right photovoltaic unit module. When it rains, rainwater will fall into the small gap flow channel between the two, and the rainwater will flow down along the small gap flow channel. In the case of strong winds, the small trickle of rainwater left in the small gap flow channel will flow back and enter the lower slot of the upper photovoltaic unit module, and flow into the upper slot of the lower photovoltaic unit module along the gap at the joint of the upper slot and the lower slot. Therefore, the bottom end of the upper slot is connected to the inside of the strip water guide groove through the opening on the left groove surface of the strip water guide groove, so that the rainwater entering the upper slot is discharged into the inside of the strip water guide groove through the opening, thereby preventing the rainwater from being deposited in the upper slot and the lower slot.

[0019] (5) The present invention is easy to install and can be installed from bottom to top. The bottom of the upper photovoltaic unit module is completely covered on the top of the lower photovoltaic unit module, so that the upward force of wind can be dispersed to the longitudinal joints of multiple photovoltaic unit modules, effectively improving the roof's anti-wind uplift capability.

[0029] The front of the photovoltaic unit module 1 is a two-step stepped surface, that is, a first step surface 14 facing upward is formed between the middle part 12 and the bottom 13 of the photovoltaic unit module 1, and a second step surface 15 facing upward is formed between the middle part 12 and the top 11 of the photovoltaic unit module 1. A row of screw locking holes 6 that pass through from front to back are arranged on the top 11 of the photovoltaic unit module 1. A cell embedded groove is arranged on the middle part 12 of the photovoltaic unit module 1. The photovoltaic cell 7 is embedded in the cell embedded groove. The left side of the photovoltaic unit module 1 and the left groove surface of the strip water guide groove 2 are both first-step stepped surfaces.
