[0043] In the utility model, water falling hole is provided on the flexible roof, and a drain pipe is arranged, the top of the drain pipe is inserted into the water falling hole, or the drain pipe is below the water falling hole, the bottom of the downspout is inserted into the water falling hole and the drain pipe, water on the flexible roof is collected at the water falling assembly, and enters the downspout through the grid type water baffle, and then the water is drained through the drain pipe. More preferably, an elastic sealing ring can be arranged on the outer surface below the downspout, or an elastic sealing ring can be arranged on the inner wall above the drain pipe, the elastic sealing ring is between the downspout and the drain pipe, and is used for sealing the connection between the downspout and the drain pipe, so that when the water discharged from the downspout enters the drain pipe and is discharged through the drain pipe, the water cannot leak from the connection between the downspout and the drain pipe. When the downspout is inserted into the water falling hole, the bottom of the downspout is directly inserted into the drain pipe to realize quick connection of the downspout and the drain pipe.

[0044] In the embodiment, the waterproof roll material is PVC waterproof roll material or TPO waterproof roll material, and the material of the sealing element is the same as that of the waterproof roll material. Therefore, when the water falling assembly is installed, the bottom of the downspout is directly inserted into the water falling hole, the bottom of the downspout is inserted into the drain pipe, and the downspout is connected with the drain pipe, then the bottom surface of the support plate is abutted on the top surface of the flexible roof to limit the downspout from falling downward, and because the size of the sealing element is greater than that of the support plate, the bottom surface of the sealing element at the outer edge of the support plate is abutted on the top surface of the flexible roof, and the sealing element and the waterproof roll material on the top of the flexible roof are connected by bonding or heat sealing, so that the sealing element and the waterproof roll material are sealed and connected, and the connection between the support plate and the waterproof roll material is sealed, so that when external water flows through the connection, water leakage does not occur. In addition, the material of the sealing element is the same as that of the waterproof roll material, so that when the sealing element deforms, the sealing element deforms with the waterproof roll material, the connection between the sealing element and the waterproof roll material does not separate, and water leakage is prevented.

[0045] More preferably, in order to ensure the firmness of the water falling assembly after installation, a plurality of mounting holes are arranged on the support plate, a positioning plate is arranged at the top outer edge of the downpipe, the positioning plate is connected with the flexible roof, a connecting screw hole is arranged on the positioning plate and faces the mounting hole, when the water falling assembly is installed, the downpipe is inserted into the water falling hole, the support plate is placed on the flexible roof, and the mounting hole faces the connecting screw hole, and the connecting bolt is screwed through the mounting hole and the connecting screw hole of the downpipe, so that the downpipe and the downpipe are connected (the mounting hole is another preferred embodiment). If the mounting hole is not provided, the support plate is directly placed on the flexible roof, and then the sealing element is placed on the support plate, the through hole faces the downpipe, the bottom surface of the sealing element has an adhesive layer, and then the adhesive layer of the sealing element is tightly connected and fixed with the top surface of the support plate by means of hot air welding, and the outer edge of the sealing element is hot air welded with the top surface of the waterproof roll, so as to realize the connection and fixation of the downpipe and the flexible roof. Then the grating type baffle is placed on the sealing element of the support plate above the downpipe, and the grating type baffle and the screw hole of the connecting frame of the downpipe are connected through the bolt, so that the grating type baffle and the downpipe are fixed. In this embodiment, the grating type baffle can block some impurities such as fallen leaves, so as to prevent the impurities from entering the downpipe, and water can smoothly enter the downpipe through the grating type baffle and be discharged. Since the grating type baffle adopts the upper convex structure, it protrudes above the support plate, and even if there is some accumulation of impurities and fallen leaves below, the upper part of the grating type baffle can still normally drain water, so as to as far as possible prevent the occurrence of blockage and prevent the problem of water accumulation on the flexible roof.

[0046] Referring to Figure 4 , 5 As shown in the figure, the grating type baffle 2 comprises an upper plate 8 and four grating plates 9, the four grating plates 9 are arranged at the outer edges of the four sides of the upper plate 8, the top of each grating plate 9 is connected with the side wall of one side of the upper plate 8, the grating plates 9 are arranged in a downward and outward inclined manner from top to bottom, and the two ends of each grating plate 9 are connected with the side portions of the adjacent grating plates 9, respectively, and the bottoms of the four grating plates 9 are arranged on the top surface of the sealing element 4 above the support plate 3.

[0050] A plurality of upper through grooves and a plurality of lower through grooves are arranged on each grid plate, the upper through grooves are arranged above the lower through grooves, when draining water, the grid plate blocks fallen leaves, impurities and the like, and drains water through the through grooves, preferably, the lower through grooves are used for draining water, when the water volume is large, the upper through grooves and the lower through grooves are used for draining water together, since the fallen leaves, impurities and the like are accumulated from bottom to top, the lower through grooves are blocked first, therefore, the upper through grooves can still be used for normal water draining. In addition, four grid plates are arranged, that is, the four surfaces of the grid type baffle can drain water, when one grid plate is completely blocked, the other grid plates can still drain water normally, so that the water accumulation or the delay of water accumulation is prevented as much as possible. The through grooves are arranged from top to bottom, which can prevent the blocking phenomenon as much as possible.

[0060] The outer ends of the connecting pieces 16 are welded to the inner surface of the downspout 1;

[0061] The screw hole 6 is coaxially arranged on the top surface of the connecting column 15.

[0062] Setting the screw hole at the top of the connecting column and coaxially arranging it inside the downspout can realize the connection between the bolt and the downspout, and is used to connect and fix the grid-type baffle and the downspout. At the same time, by connecting the connecting piece and the inner wall of the downspout, the connection between the connecting column and the downspout is realized.
