[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] In the description of this utility model, the terms "upper", "lower", "above", "both ends", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] Reference Figure 1-2As shown, this embodiment provides a component cover plate for BIPV waterproofing. The component cover plate includes a waterproof part 1. The cross-section of the waterproof part 1 is generally arched. Both ends of the waterproof part 1 are vertically folded upward to form a fastening part 2. The tops of the two sets of fastening parts 2 are bent and extended in opposite directions to form a water guiding part 3. The end of the water guiding part 3 away from the fastening part 2 is bent downward to form an enclosing part 4. The component cover plate is formed in one step by roll forming of zinc-aluminum-magnesium steel plate.

[0020] The component cover made of zinc-aluminum-magnesium steel sheet is cheaper than aluminum alloy material. By promoting BIPV and replacing extrusion molding with roll forming, the component cover made of zinc-aluminum-magnesium steel sheet can completely cover the main water tank.

[0021] Furthermore, multiple sets of fastening blocks 6 are provided on the side of the fastening part 2 away from the waterproof part 1, and the fastening blocks 6 cooperate with the grooves of the middle pressure block 5.

[0022] By setting the fastening block 6 in conjunction with the intermediate pressure block 5, the component cover plate and the intermediate pressure plate can be tightly joined together, making it difficult to fall off. This can completely cover the gap between the component cover plate and the intermediate pressure plate, preventing a large amount of rainwater from entering the main water tank, and also preventing fallen leaves and other debris from entering the main water tank.

[0023] Furthermore, the included angle between the fastening part 2 and the water guiding part 3 is an acute angle greater than 60 degrees.

[0024] By setting the included angle between the fastening part 2 and the water guiding part 3 to an acute angle greater than 60 degrees, the tilt between the fastening part 2 and the water guiding part 3 becomes gentle, thus preventing rainwater from splashing due to excessive tilt when it drips.

[0025] Furthermore, the height of the fastening part 2 is higher than the height of the waterproof part 1.

[0026] Furthermore, the fastening part 2 and the waterproof part 1 are tightly fitted together.

[0027] This design prevents rainwater or fallen leaves and other debris from entering the gap between the fastening part 2 and the waterproof part 1, thus avoiding difficulties in cleaning.

[0028] Furthermore, the height of the fastening block 6 is lower than the highest position of the waterproof part 1.

[0029] This design allows the fastening between the fastening block 6 and the groove to become tighter through the compression of the waterproof part 1, making it less likely for the component cover plate and the intermediate pressure plate to fall off.

[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
