Referring further to fig. 1B, the present utility model also provides a photovoltaic system 100 comprising a plurality of purlins 30 (only one shown in fig. 1B for angular reasons), a plurality of photovoltaic modules 10, and a drainage channel 110, the plurality of photovoltaic modules 20 being disposed on the plurality of purlins 30, the drainage channel 110 being disposed on the purlins 30 between profiles 500 of two adjacent photovoltaic modules 10. To secure the photovoltaic module 10, the photovoltaic system further includes a plurality of first and second pressure plates 120, 130 and a plurality of first and second fasteners 140, 150. The first and second pressing plates 120 and 130 press the first and second supporting plates 117 and 118 of the drain tank 110, respectively. It will be appreciated that there is no direct contact between the first and second platens 120, 130 and the first and second pallets 117, 118, but rather the fixing portion 510 of the profile 500 is sandwiched. For ease of understanding, the following is described in connection with the left portion of FIG. 1: the right side of the outer side surface of the supporting part 530 is closely attached to the first side plate 113 of the drain tank 110, and the lower surface of the fixing part 510 is closely attached to the first supporting plate 117, i.e., the fixing part 510 of the profile 500 is located above the first supporting plate 117. The first pressing plate 120 presses against the fixing portion 510 of the profile 500, and fixes the profile 500 and the drain groove 110 in the longitudinal direction.

Specifically, in this embodiment, the first pressing plate 120 and the second pressing plate 130 include a pressing plate 121/131 and a supporting plate 122/132, respectively, the pressing plate 121/131 is used for pressing the corresponding first supporting plate 117 or second supporting plate 118, and the supporting plate 122/132 is connected to the pressing plate 121/131. The support plates 122/132 have fastening holes 123/133 in the embodiment shown in fig. 1, and the support plates 122/132 have a semi-enclosed rectangular shape, and the other ends thereof, which are not connected to the crimp plates 121/131, abut against the purlins 30.

Further, the first and second fasteners 140 and 150 fix the first and second platens 120 and 130, respectively. Also taking the left part of fig. 1 as an example: the first fastener 140 in this embodiment includes a fastening piece 141, a fastening nut 142 and a fastening bolt 143, the fastening piece 141 is located under the purline 30, the fastening nut 142 is located under the fastening piece 141, and the fastening bolt 143 sequentially passes through the fastening nut 142, the fastening piece 141 and the purline 30, and finally passes through the fastening hole 123 in the support plate 122 of the first platen 120.

The second fastening member 150 in the right part of fig. 1 also includes a fastening tab 151, a fastening nut 152, and a fastening bolt 153, and the specific connection thereof will not be repeated here.

It can be appreciated that the fastening holes 123/133 of the first and second pressing plates 120/130 are located on the supporting plates 122/132 in the present embodiment, and the fastening bolts 143/153 do not need to pass through the profile 500 after the installation is completed, so that the fixing portion 510 of the profile 500 does not need to perform a punching operation, and damage to the strength of the profile is reduced compared with the prior art. The arrangement of the fastening pieces 141/151 reduces the pressure of the fastening nuts 142/152 on the purlines 30, and achieves the technical effect of protecting the purlines 30.

Fig. 2 is a schematic view of another drainage channel and photovoltaic module installation according to a first embodiment of the present utility model. In comparison with the embodiment shown in fig. 1, the lower edges of the first side plate 113 'and the second side plate 114' in the drainage channel 110 'are lower than the bottom plate 112', i.e. two sides of the bottom plate 111 'are respectively connected with the first side plate 113' and the second side plate 114 'near the lower edges, and the first supporting plate 117' and the second supporting plate 118 'respectively extend horizontally outwards from two sides of the lower edges of the first side plate 113' and the second side plate 114 'in the U-shaped channel 111', i.e. the first supporting plate 117', the second supporting plate 118' and the bottom plate 112 'are not located at the same level, but the first supporting plate 117', the second supporting plate 118 'are lower than the bottom plate 112'.

Fig. 3 is a schematic partial cross-sectional view of a photovoltaic system according to a first embodiment of the present utility model. Preferably, in comparison with the embodiment shown in fig. 1, the edge of the first supporting plate 117 "far from the U-shaped groove 111" in the drainage groove 110 "in the photovoltaic system 100" in the embodiment shown in fig. 3 has a first protruding strip 117a, and the edge of the second supporting plate 118 "far from the U-shaped groove 111" has a second protruding strip 118a. The first raised line 117a and the second raised line 118a can play a limiting role on the first pressing plate 120 "and the second pressing plate 130" in the horizontal direction, so that the first pressing plate 120 "and the second pressing plate 130" are prevented from generating displacement, and the 500 fixing strength of the profile is ensured; meanwhile, the first raised line 117a, the second raised line 118a and the U-shaped groove 111″ form a first auxiliary water groove 119a and a second auxiliary water groove 119b, respectively, so that leakage water caused by gaps generated by artificial uncompacted water grooves can be collected and discharged. Or, in case of a large amount of rain, leakage occurs between the profile 500 and the first and second side plates 213 and 214, and the leakage water is collected and discharged by the sub-tank. The first and second protrusions 117a and 118a are longitudinally elevated above the upper surfaces of the first and second pallets 217 and 218 to form the sub-water tank.

The slot 210 also has a first connection plate 215, a second connection plate 216, a first pallet 217, and a second pallet 218.

The drain tank 210 according to the third embodiment is different from the drain tank 110 according to the first embodiment in that the U-shaped tank 211 is different from the drain tank 110 according to the first embodiment in that, referring to fig. 4B, the first side plate 213 and the second side plate 214 of the drain tank 210 are lower than the profile 600, and the first connecting plate 215 and the second connecting plate 216 are straight and extend obliquely upward from the top of the first side plate 213 and the second side plate 214, respectively, which can increase the contact area between the first connecting plate 215 and the second connecting plate 216 and the profile 600, and enhance the fixing effect. In addition, the inclined upward extension of the first and second connection plates 215 and 216 also reduces the risk of rain leakage: in the case of a large amount of rain, the rain water may temporarily accumulate in the U-shaped groove 211, resulting in an increase in the level of the U-shaped groove 211, and leakage occurs when the level rises beyond the highest point of the drainage groove 200, as in the embodiment shown in fig. 3, the first connection plate 215 and the second connection plate 216 extend obliquely upward to achieve the effect of increasing the height of the highest point of the drainage groove 200, thereby reducing the risk of rain leakage.

Specifically, the side of the supporting portion 630 in this embodiment has a slot 631. It will be appreciated that the slot 631 of the profile 600 is adapted to be used to receive either the first connection plate 215 or the second connection plate 216 of the drain tank 210, as shown in fig. 4B to 5, the slot 631 of the profile 600 also extends obliquely upwards from the side of the support portion 630, and in a direction inboard of the support portion 630, i.e. extending obliquely upwards from the side of the support portion 630 remote from the fixing portion 610 towards the side of the support portion 630 adjacent to the fixing portion 610.
