However, such roofs have complex curved surfaces, large slopes, fast rainwater runoff speed and extremely uneven distribution, which puts high requirements on the adaptability, anti-clogging ability and anti-freezing ability of the drainage system in cold environments. If the drainage system cannot efficiently adapt to the roof structure, it is easy to cause roof leakage, structural damage and other problems, and even pipe rupture due to ice formation in cold weather, which seriously affects the service life and safety of the building, so it is an urgent need in the field to develop a drainage device with strong adaptability and perfect functions.

[0037] Example 4, refer to Figures 1-6 Figures 1-6 The construction method of the adaptive drainage device for a multi-curved and large-slope tile roof comprises the following steps:

[0038] S1: Install the rainwater collection frame 1 on the roof rainwater collection area, adapt the rainwater collection frame 1 to the roof slope; connect the water outlet pipe 6 to the rainwater collection frame 1 and the drain pipe 7, install the support plate 8 on the top of the drain pipe 7, fix the protective shell 9 on the support plate 8, assemble the heating assembly 10 in the protective shell 9, and wrap the hot compress coating 11 on the surface of the drain pipe 7, and set the protective shell 12;

[0039] S2: Insert the plug 17 of the filter screen 4 into the slot 16 of the rainwater collection frame 1, rotate the rotating disc 302 of the installation assembly 3 in the outer shell 2, move the threaded sleeve 303 through the bidirectional threaded rod 301, push the inclined block 305 and the baffle 306 with the movable wheel 304, and insert the clamping block 307 into the groove of the limiting plate 5 to complete the fixation of the filter screen 4;

[0040] S3: After the rainwater is filtered by the filter screen 4, it enters the rainwater collection frame 1 and flows into the drain pipe 7 through the water outlet pipe 6; in cold environments, start the fan 1002 and heating wire 1003 of the heating assembly 10, and heat the drain pipe 7 through the heating pipe 1005, and cooperate with the hot compress coating 11 to prevent the pipe from freezing;

[0041] S4: When cleaning or replacing the filter screen 4, reverse rotate the rotating disc 302, and the spring 308 rebounds to drive the clamping block 307 to disengage from the limiting plate 5, so that the filter screen 4 can be removed.

[0042] In use, the prefabricated drain pipe module is customized according to the specific curved surface and large slope of the roof; the intelligent drainage control device is located in the prefabricated drain pipe module, which is used for real-time water flow analysis, path optimization and water flow speed and direction prediction; the intelligent drainage outlet is distributed on the roof to facilitate smooth water flow into the drainage system; the rainwater collection and reuse device is used to collect roof precipitation and reuse; the energy efficiency management system optimizes the energy consumption of the drainage system through intelligent control; the anti-freezing system includes heating elements integrated in the prefabricated drain pipe module and surface coatings for continuous and reliable operation of the system under cold conditions; the user interface and remote monitoring system allow users to remotely monitor and manage the operating status of the drainage system through the application or web interface. First, fix the filter screen 4 by the plug 17 and the installation assembly 3 according to the steps, then drain the filtered rainwater, start the heating assembly 10 to prevent the pipe from freezing in cold weather, reverse rotate the rotating disc 302 to clean the filter screen 4, efficiently complete the device construction and ensure its stable operation and convenient maintenance.

[0043] Working principle: When the rainwater falls on the multi-curved large slope tile roof, it will converge into the rainwater collecting frame 1. At this time, the filter screen 4 at the top of the inner cavity of the rainwater collecting frame 1 filters the rainwater, blocking impurities in the rainwater to avoid blockage of the subsequent drainage channel. The filter screen 4 is fixed by the cooperation of the limiting plates 5 on both sides and the installation assembly 3 in the rainwater collecting frame 1: first, insert the plug blocks 17 on the front and back sides of the filter screen 4 into the slot 16 on the front and back sides of the inner cavity of the rainwater collecting frame 1 to assist in accurate positioning of the filter screen 4; then rotate the rotating disc 302 at the top of the outer shell 2, the rotating disc 302 drives the bidirectional threaded rod 301 to rotate, and the two threaded sleeves 303 on the surface of the bidirectional threaded rod 301 move vertically along the sliding rod 310 (the sliding block 309 slides on the sliding rod 310 to guide the stable movement of the threaded sleeve 303); the movable wheels 304 on the front and back sides of the threaded sleeve 303 push the inclined blocks 305, so that the baffle 306 moves horizontally along the positioning rod 312 (the positioning block 311 slides on the positioning rod 312 to guide the smooth movement of the baffle 306), and finally the clamping block 307 on the baffle 306 is clamped into the preset groove of the limiting plate 5 to complete the stable installation of the filter screen 4. The filtered rainwater flows to the drain pipe 7 through the water outlet pipe 6 at the bottom of the rainwater collecting frame 1, and the electromagnetic valve 15 on the surface of the water outlet pipe 6 can control the opening and closing of the water outlet pipe 6, thereby realizing the quantitative collection and discharge of rainwater, and the drain pipe 7 can adapt to the drainage path of the multi-curved large slope roof to smoothly guide the rainwater out.

[0044] When in cold conditions, the heating assembly 10 in the inner cavity of the protective shell 9 is started: the fan 1002 sends air to the inside of the heating box 1001, and the airflow is heated into hot air after passing through the three heating wires 1003 in the heating box 1001; the hot air enters the heating pipe 1005 around the drain pipe 7 through the two air outlet pipes 1004 on the left side of the heating box 1001 to heat the drain pipe 7. At the same time, the hot compress coating layer 11 wrapped on the surface of the drain pipe 7 enhances the anti-freezing performance of the pipe, and can also accelerate the ice melting on the outer wall of the pipe, and the protective shell 12 on the surface of the hot compress coating layer 11 protects the hot compress coating layer 11 from external damage, both of which cooperate to prevent the rainwater in the drain pipe 7 from freezing. If it is necessary to clean or replace the filter screen 4, the rotating disc 302 is rotated in the opposite direction, the bidirectional threaded rod 301 is reversely rotated to make the threaded sleeve 303 move back, the spring 308 on one side of the baffle 306 rebounds to reset the baffle 306, and the clamping block 307 is separated from the groove of the limiting plate 5, at which time the filter screen 4 can be taken out for cleaning or replacement operation. In addition, the cover plate 14 at the top of the outer shell 2 can cover the top opening of the outer shell 2 in the non-maintenance state to prevent rainwater and dust from entering the inside of the outer shell 2 and damaging the installation assembly 3.
