[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0029] The present invention provides a technical solution:

[0030] Please refer to Figures 1 to 3 , a photovoltaic floor applying an isocyanate-modified adhesive film, which includes a housing assembly 1. Inside the housing assembly 1, a photovoltaic module 2 is provided, and a bottom support assembly 3 for support is provided below the housing assembly 1. A waterproof rubber strip 4 is provided between the photovoltaic module 2 and the housing assembly 1, and a connecting groove 5 for connecting the photovoltaic module 2 and the housing assembly 1 is opened at the top of the waterproof rubber strip 4;

[0031] The photovoltaic module 2 includes anti-slip glass 201. Below the anti-slip glass 201, solar cells 203 are provided, and below the solar cells 203, a bottom glass 204 is provided. Isocyanate-modified adhesive layers 202 are provided between the solar cells 203 and both the anti-slip glass 201 and the bottom glass 204;

[0032] Flow guide grooves 205 and anti-slip grooves are alternately arranged on the top of the anti-slip glass 201, and the flow guide grooves 205 communicate with the connecting groove 5;

[0033] The housing assembly 1 includes a support frame 101. A drainage groove 102 is opened at the top of the support frame 101, and a drainage hole 103 is provided at the end of the drainage groove 102. The waterproof rubber strip 4 is adhesively connected to the photovoltaic module 2 and the housing assembly 1. Both ends of the connecting groove 5 are respectively connected to the flow guide groove 205 and the drainage groove 102, and the depth in the middle of the flow guide groove 205 is less than the depths on both sides of the flow guide groove 205.

[0034] By adopting the above technical solution, two different acrylic monomers EHA and CEA are mixed in a ratio of 7:3 (mol%), 0.15% mo1,3-bis(isocyanatomethyl)cyclohexene is added as a cross-linking agent. To control the viscosity of the mixture, hydrophobic fumed silica (12 phr) is added as an inorganic filler, and a photoinitiator (phenylbis(2,4,6-trimethylbenzoyl)phosphine oxide) (0.1 mol%) is added, and it is mixed with a vortex mixer to make a glue solution; the glue solution is applied on tempered glass, and it is laid in the order of anti-slip glass 201 - glue solution - solar cells 203 - glue solution - bottom glass 204. The solar cells 203 should use thin-film solar cells to maximize the light transmittance, and it is cured for 1 min under a nitrogen atmosphere using a black light. The ultraviolet intensity of this lamp is about 1 W / cm2, and then the sample is slowly reversed using a robotic arm, and the back of it is cured again using a black light to make it completely cured. The glue solution forms an isocyanate-modified adhesive layer 202, and it is produced by a photo-curing method to improve the efficiency;

[0035] Rainwater can flow directly along the diversion groove 205 to the connection groove 5, and through the connection groove 5 to the drainage groove 102, and is directly discharged below the housing assembly 1 through the drainage hole 103. Since the housing assembly 1 is arranged on the bottom support assembly 3 and is higher than the construction plane, during construction, after the construction surface is cured, a drainage system is laid, so that rainwater can be directly discharged into the drainage system through the drainage hole 103, thereby improving the drainage efficiency.

[0036] Specifically, as Figure 4 and Figure 5 shown, the bottom support assembly 3 includes a waterproof base 301. The size of the waterproof base 301 is smaller than that of the support frame 101. Damping rods 305 are arranged at the four corners inside the waterproof base 301. A rubber plate 304 is arranged at the top of the damping rod 305. A damping spring 306 is sleeved on the surface of the damping rod 305. The two ends of the damping spring 306 are respectively connected to the waterproof base 301 and the rubber plate 304. And the rubber plate 304 is arranged at the four corners below the photovoltaic module 2. The bottom support assembly 3 further includes a limit bracket 302 located in the middle of the waterproof base 301, and a buffer bracket 303 sleeved inside the limit bracket 302. The buffer bracket 303 is arranged in the middle below the photovoltaic module 2. The top of the buffer bracket 303 is a hollow mesh structure.

[0037] By adopting the above technical solution, after the photovoltaic module 2 is stressed, the force can be transmitted into the rubber plate 304 and the buffer bracket 303. A number of damping blocks are arranged between the buffer bracket 303 and the limit bracket 302. By using the damping rod 305 and the damping spring 306, a certain buffering effect is provided. And because the bottom of the bottom layer glass 204 is not completely blocked, to a certain extent, it can assist in dissipating heat from the surface of the bottom layer glass 204.

[0038] Working principle: Rainwater can flow directly along the diversion groove 205 to the connection groove 5, and through the connection groove 5 to the drainage groove 102, and is directly discharged below the housing assembly 1 through the drainage hole 103. Since the housing assembly 1 is arranged on the bottom support assembly 3 and is higher than the construction plane, during construction, after the construction surface is cured, a drainage system is laid, so that rainwater can be directly discharged into the drainage system through the drainage hole 103, thereby improving the drainage efficiency. After the photovoltaic module 2 is stressed, the force can be transmitted into the rubber plate 304 and the buffer bracket 303. A number of damping blocks are arranged between the buffer bracket 303 and the limit bracket 302. By using the damping rod 305 and the damping spring 306, a certain buffering effect is provided. And because the bottom of the bottom layer glass 204 is not completely blocked, to a certain extent, it can assist in dissipating heat from the surface of the bottom layer glass 204.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
