[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example: Please refer to Figures 1-6 A prefabricated self-opening and closing rainwater inlet includes a rainwater hopper 1, a metal curtain wall 2 on the right side of the rainwater hopper 1, a drainage riser 3 fixedly connected to the top of the rainwater hopper 1, a first U-shaped groove 4 bent at the upper and lower ends of the right side of the rainwater hopper 1, a rear baffle 5 bent at the front end of the right side of the rainwater hopper 1, a water outlet 8 opened inside the metal curtain wall 2, a second U-shaped groove 6 bent at the upper and lower ends of the left side of the water outlet 8, a front baffle 7 bent at the rear end of the left side of the water outlet 8, a stainless steel sealing plate 9 inside the water outlet 8, two sets of stainless steel hinges 10 installed at the top of the left side of the stainless steel sealing plate 9, and a magnetic strip 11 fixedly connected to the bottom end inside the water outlet 8.

[0028] The drainage riser 3 is a 125mm*65mm oval flat pipe. The rainwater hopper 1 and the drainage riser 3 are connected internally. The outlet 8 runs through the left and right sides of the metal curtain wall 2. The rainwater hopper 1 and the outlet 8 are connected internally. The stainless steel hinge 10 is connected to the top of the outlet 8. The stainless steel sealing plate 9 is hinged inside the outlet 8 through the stainless steel hinge 10. The bottom end of the stainless steel sealing plate 9 is attached to the top end of the magnet strip 11. The front and rear ends of the stainless steel sealing plate 9 are attached to the front and rear ends of the outlet 8. It can open and close automatically according to water pressure.

[0029] A flexible hose 12 is connected to the bottom of the drainage riser 3, and a clamp 13 is connected between the flexible hose 12 and the drainage riser 3. The bottom of the flexible hose 12 extends into the interior of the rainwater hopper 1.

[0030] The magnetic strip 11 is used to calculate the equilibrium force point of the adsorption force and to conduct a simulation test. The magnetic strip 11 can be a strong metal magnet (such as a metal magnet or a neodymium magnet). When the water pressure in the drainage riser 3 is greater than the adsorption force of the magnetic strip 11, the water pressure will push open the stainless steel sealing plate 9 to drain the water. When the water pressure is less than the adsorption force of the stainless steel sealing plate 9, the stainless steel sealing plate 9 will close, thereby achieving the effect of automatic closure of the water outlet 8.

[0031] The bearing capacity of the first U-shaped slide 4 and the second U-shaped slide 6 was calculated and simulated to test the reliability of the connection between the rainwater hopper 1 and the metal curtain wall 2, so that it would not be knocked off by the vertical impact force of rainwater. In the laboratory simulation test, when the rigidity of the first U-shaped slide 4 and the second U-shaped slide 6 is insufficient, the material thickness of the rainwater hopper 1 and the metal curtain wall 2 can be appropriately increased to improve the connection reliability of the first U-shaped slide 4 and the second U-shaped slide 6.

[0032] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the stainless steel sealing plate 9 at the bottom of the water outlet 8 is attracted by the magnetic strip 11, blocking the water outlet 8. When the rainfall is small, there is little rainwater inside the rainwater hopper 1, and the stainless steel sealing plate 9 remains closed, with rainwater accumulating in the rainwater hopper 1. As the amount of water in the rainwater hopper 1 increases, or when the rainfall is large, the water pressure in the rainwater hopper 1 exceeds the magnetic attraction of the magnetic strip 11, and the stainless steel sealing plate 9 is pushed open by the water pressure, thus starting to drain water. As the water pressure decreases, the stainless steel sealing plate 9 returns to its original position and is re-attracted by the magnetic strip 11. The type of curtain wall panel can be changed in size, finish, material, etc., according to actual construction needs.

[0033] The external shape and size of the first U-shaped slide 4 are matched with the internal shape and size of the second U-shaped slide 6. The first U-shaped slide 4 can slide back and forth along the inside of the second U-shaped slide 6. The rear end of the rear baffle 5 is in contact with the front end of the second U-shaped slide 6. The right side of the rear baffle 5 is in close contact with the right side of the metal curtain wall 2. The front end of the front baffle 7 is in contact with the rear end of the rainwater hopper 1. The sealing is good and it is not easy to leak.

[0034] Specifically, such as Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, apply sealant to the second U-shaped groove 6, attach a sealing strip to the left front edge 7 of the water outlet 8 of the metal curtain wall 2, attach a sealing strip to the right rear edge 5 of the rainwater hopper 1, align the first U-shaped groove 4 of the rainwater hopper 1 with the second U-shaped groove 6 of the metal curtain wall 2 and push it in forcefully.

[0035] The top of the stainless steel sealing plate 9 fits into the top of the inside of the water outlet 8, and the right side of the metal curtain wall 2 and the stainless steel sealing plate 9 are flush, resulting in good integration and aesthetics.

[0036] Specifically, such as Figure 1 , Figure 4 and Figure 5 As shown, the sides of the metal curtain wall 2 and the stainless steel sealing plate 9 are flush.

[0037] Working principle: Before installation, firstly, apply sealant to the second U-shaped groove 6. Then, attach a sealing strip to the left front edge 7 of the outlet 8 of the metal curtain wall 2 and to the right rear edge 5 of the rainwater hopper 1. Align the first U-shaped groove 4 of the rainwater hopper 1 with the second U-shaped groove 6 of the metal curtain wall 2 and push it in forcefully. Next, check if the sealing strips on the rear edge 5 and the front edge 7 are tightly pressed, and check the sealant compaction within the groove. After ensuring the sealing between the rainwater hopper 1 and the metal curtain wall 2 meets the requirements, connect the hose 12 to the drainage riser 3 via the clamp 13. Finally, insert the hose 12 into the upper opening of the rainwater hopper 1. To prevent water from splashing from the lower end of the drainage riser 3 onto the outside of the rainwater hopper 1, rainwater from the roof flows downwards from the drainage riser 3 into the rainwater hopper 1 and accumulates there. The stainless steel sealing plate 9 at the bottom of the outlet 8 is attracted by the magnetic strip 11, sealing the outlet 8. When the rainfall is low, there is little rainwater inside the rainwater hopper 1, and the stainless steel sealing plate 9 remains closed, accumulating rainwater in the rainwater hopper 1. As the water volume in the rainwater hopper 1 increases, or when the rainfall is heavy, the water pressure in the rainwater hopper 1 exceeds the magnetic attraction of the magnetic strip 11, and the stainless steel sealing plate 9 is pushed open by the water pressure, thus starting drainage. As the water pressure decreases, the stainless steel sealing plate 9 returns to its original position and is re-attracted by the magnetic strip 11. The sides of the metal curtain wall 2 and the stainless steel sealing plate 9 are flush and have the same pattern, resulting in strong aesthetics and a unified appearance within the building. After the entire drainage outlet structure is connected, a water filling test is conducted on the drainage riser 3 to ensure that the rainwater hopper 1 is tightly connected to the metal curtain wall 2 and there is no side leakage. Then, the last piece of metal curtain wall 2 of the bracket column is sealed.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
