This main water tank can effectively connect and fix photovoltaic modules and play a role in drainage at the same time. However, the structure of this main water tank is relatively complex, especially when installing with other parts, it is very inconvenient. Moreover, the existing main water tank has a large thickness and high cost; the main water tank with a thin-walled structure cannot be welded and the installation is very inconvenient.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The present invention will be further described in detail below with reference to the drawings and embodiments.

[0021] Embodiment 1

[0022] A fixed connection structure for a main water tank 2, comprising a main beam 1. A main water tank 2 for supporting a photovoltaic module is placed on the main beam 1, and the main water tank 2 is fixed to the main beam 1 through a clamping seat 9. The main water tank 2 includes a tank body, and the tank body is composed of a first side plate 4 and a second side plate 5 that are vertically parallel to each other and a bottom plate connecting the first side plate 4 and the second side plate 5. The upper end of the first side plate 4 is bent towards the middle 3 of the tank body to form a first baffle 6, and the upper end of the second side plate 5 is bent towards the middle 3 of the tank body to form a second baffle 7. The first baffle 6 and the second baffle 7 are arranged parallel to the bottom plate. The clamping seat 9 includes a clamping portion 10 and a fixing portion 11. The fixing portion 11 is fixedly installed on the main beam 1, and the clamping portion 10 is clamped on the first baffle 6, the second baffle 7, the first side plate 4, and the second side plate 5. The main beam 1 serves as a support for the entire photovoltaic system and plays a main load-bearing role. In the prior art, square tubes or channel steels are generally used. The main water tank 2 on the one hand directly supports the photovoltaic module, and on the other hand is used as a drainage channel for the photovoltaic module. In the prior art, the main water tank 2 is generally fixed by welding steel or by clamping with a clamp. In this solution, the first side plate 4, the second side plate 5, the first baffle 6, the second baffle 7, and the bottom plate are a thin-walled steel structure with an integrally formed structure, which has the advantage of light weight. The clamping limits the first baffle 6 and the second baffle 7, thereby reducing the force directly acting on the main water tank 2 and improving the anti-deformation ability of the main water tank 2.

[0023] In this solution, the first side plate 4 and the second side plate 5 are vertically arranged. The clamping portion 10 includes an upper limiting plate 16 and a lower limiting plate 17. A clamping groove 13 is formed between the upper limiting plate 16 and the lower limiting plate 17. During installation, the clamping groove 13 can be directly inserted onto the first baffle 6 and the second baffle 7 to achieve installation positioning. The width of the clamping groove 13 is equal to the thickness of the first baffle 6 or the second baffle 7. The upper limiting plate 16 and the lower limiting plate 17 are connected at one end close to the middle 3 of the tank body, and the connection part seals the end of the first baffle 6 or the second baffle 7. In this embodiment, the clamping seat 9 is installed on the first baffle 6 and the first side plate 4, and the clamping seat 9 is also installed on the second baffle 7 and the second side plate 5.

[0024] The other end of the lower limiting plate 17 is bent downward to form a third baffle 8. The third baffle 8 is vertically arranged, and the third baffle 8 abuts against the side of the first side plate 4 or the second baffle 7 close to the middle 3 of the tank body. The third baffle 8 improves the lateral anti-deformation ability of the first side plate 4 and the second side plate 5.

[0025] The fixing portion 11 is a plate structure. The fixing plate is fixed to the main beam 1 like a base. Since the inner sides of the first side plate 4 and the second side plate 5 are already supported by the baffles, in order to maintain the positioning of the first side plate 4 or the second side plate 5, the fixing portion 11 abuts against the outer side of the first side plate 4 or the second side plate 5. Thus, the side plate is positioned with forces on both sides.

[0026] Wherein, the clamping part 10 and the fixing part 11 are connected through the connecting part 12. The connecting part 12 includes a vertical part 14 fixedly installed on the fixing part 11 and an arc part 15 connected to the clamping part 10. The vertical part 14 is arranged in parallel with the first side plate 4 and the second side plate 5. The clamping part 10, the fixing part 11 and the connecting part 12 are of an integral structure, and the arc part 15 extends from the tail of the upper limit plate 16. A fixing hole is arranged on the left side of the vertical part 14, and the screw 18 is fixedly connected with the main beam 1 through the fixing hole; the right side of the vertical part 14 abuts against the outside of the first side plate 4 or the second side plate 5.

[0027] Embodiment 2

[0028] The difference between this embodiment and Embodiment 1 is that: the clamping part 10 and the connecting part 12 have the ability of elastic deformation.

[0029] Embodiment 3

[0030] The difference between this embodiment and Embodiment 1 is that: the wall thickness of the main water tank 2 is 1 mm to 2 mm.
