Detailed Description
The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.
The general roof is the tilt state, and photovoltaic module has a plurality ofly, arranges the roofing in the array form, can collect the illumination better. When the array is arranged, a gap is reserved between the adjacent photovoltaic modules, so that the influence on the waterproof performance of the whole house caused by the fact that rainwater falls into the gaps of the photovoltaic modules is avoided. Therefore, a waterproof mounting structure with the installation function of the photovoltaic module needs to be designed.

Take utility model CN201721455855.9 discloses a photovoltaic roofing drainage system as an example, this system has higher roofing waterproof performance, but its structure is comparatively complicated. The mounting groove is held between two water drainage tank of main basin, and although installation mechanism and water drainage tank can be kept apart to the mounting groove, avoid installation mechanism infiltration, nevertheless main basin need increase a mounting groove, then when fixed to photovoltaic module, need arrange installation mechanism in the mounting groove, with main basin, horizontal basin, photovoltaic module, four location match backs of mounting groove, utilize installation mechanism fixed. In the process, a step of arranging the installation mechanism in the installation groove, a step of arranging the installation mechanism relative to the photovoltaic module, positioning and fixing the installation mechanism relative to the transverse water tank and a step of adjusting the position of the installation mechanism in the installation groove are required. If the mounting groove and the main water tank are not integrally formed, a step of fixing the mounting groove in the main water tank is required to be added.
In addition, the structure has the problem of unstable structure under long-term use. The water drainage tank of main basin is located its middle part, and photovoltaic module surface water falls into main basin on the one hand and directly gets into water drainage tank, and on the other hand falls into horizontal basin, then falls into water drainage tank. This will lead to main basin middle part as the carrier of main displacement, under long-term the use, main basin middle part structural support power is weakened, in addition still need set up the mounting groove in the water drainage tank, will set up installation mechanism again in the mounting groove, and the pressure that receives at main basin middle part increases. Generally, main basin is along a plurality of photovoltaic module vertical settings that are to arrange in line, then main basin design is longer relatively, when main basin middle part carried more power, and main basin is easy to be out of shape from the middle part in long-term use, and main basin both sides installation support is between horizontal basin and structural support beam, can seriously, can lead to main basin to be in the fracture of its middle part department, and this will unable support photovoltaic module, also unable drainage.
Based on the defects, the invention provides the photovoltaic roof installation structure which is simple in structure and convenient to install, can firmly install the photovoltaic module on the roof and can prevent water.

The supporting and drainage structure is arranged below the photovoltaic module 1, and the structural support piece 9 is arranged below the supporting and drainage structure. The supporting and drainage structure comprises a longitudinal guide rail 3, a transverse guide rail 2, a pressing strip 4, a first fixing assembly and a second fixing assembly. The longitudinal guide rail 3 is provided with three longitudinal guide grooves 31, and the top ends of two groove walls of the middle guide groove are respectively abutted to the bottom surfaces of the two adjacent photovoltaic modules 1, so that the middle guide groove is positioned below the gap between the two adjacent photovoltaic modules 1. The transverse guide rail 2 is provided with a transverse guide groove, two groove walls on the side of the longitudinal guide rail 3 are respectively abutted to the bottom surfaces of the transverse guide rails installed at the bottoms of the adjacent two photovoltaic modules 1, so that the side groove of the longitudinal guide rail 3 is communicated with the transverse guide groove of the corresponding transverse guide rail 2, namely the transverse guide groove can guide water into the side groove of the longitudinal guide rail 3.

Meanwhile, the top ends of the groove walls of the middle guide groove of the longitudinal guide rail provide supporting force for the photovoltaic module, and the top ends of the two groove walls of the side of the longitudinal guide rail 3 provide supporting force for the transverse guide rails on the two sides of the longitudinal guide rail. Each part of the longitudinal guide rail is dispersed and supported and is divided into three paths for drainage, and the weight is not completely concentrated in the middle of the longitudinal guide rail, so that the structural installation stability is ensured. Meanwhile, three ways of drainage improve the drainage efficiency. In addition, the first fixing assembly does not need to depend on the position of the mounting groove, and the pressing strip can be mounted between two adjacent photovoltaic assemblies as long as each groove wall of the longitudinal guide rail is abutted to the corresponding position, so that the photovoltaic assemblies can be mounted quickly. In this way, the roof can be arranged in order all the photovoltaic modules in a quick array mode.

The second extending wall is not required to be too long, and the spacing distance between the second extending walls of the two groove walls is just the spacing distance between the two adjacent photovoltaic modules after the two adjacent photovoltaic modules are stably arranged and installed. In another embodiment, the top ends of the two walls of the middle guide groove are provided with third extending walls 34, the third extending walls 34 extend horizontally towards the sides of the longitudinal guide rail, and the third extending walls 34 are tightly attached to the bottom surface of the photovoltaic module, i.e. the stress area of the top ends of the walls of the middle guide groove is increased. The third extending wall does not need to be too long, and can support the photovoltaic module and simultaneously prevent the transverse guide groove from guiding water to the longitudinal guide groove. In another embodiment, the presence of both the second extension wall 33 and the third extension wall 34, which are in the same plane, can support two adjacent photovoltaic modules more firmly.
