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.

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.
Fig. 4A is a front view of a drainage tank according to a third embodiment of the present utility model, and fig. 4B is a schematic partial cross-sectional view of a photovoltaic system according to a third embodiment of the present utility model. Referring to fig. 4A-4B, a drainage channel 210 according to a second embodiment of the present utility model is also provided with a U-shaped channel 211, and the U-shaped channel 211 includes a bottom plate 212, a first side plate 213 and a second side plate 214 respectively located at two sides of the bottom plate 211. 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.
