The abutting portion 3125 is configured to elastically deform the waterproof layer 13 after abutting the waterproof layer 13, so that the waterproof layer 13 forms a small inclined surface at a position close to the water diversion member 312, and a structure similar to a bell mouth is formed as a whole, and rainwater staying on the roof body 1 can flow along the end surface of the waterproof layer 13 in a direction close to the water diversion member 312.
Referring to fig. 3, the water diversion member 312 is fixedly connected with a rod body 7, the rod body 7 is in a cylindrical rod-shaped structure, the axis of the rod body 7 coincides with the axis of the water diversion member 312, one end of the rod body 7 in the axial direction is located in the cavity 3121, and the other end of the rod body 7 in the axial direction penetrates into the water diversion pipe 311. The end of the rod body 7 away from the cavity 3121 is rotatably connected with a flow dividing member 8 having a flow dividing function, the rotation axis of the flow dividing member 8 coincides with the axis of the rod body 7, and the flow dividing member 8 is located in the water conduit 311. The splitter 8 includes a plurality of splitter blades 81, the splitter blades 81 are in an arc-shaped sheet structure, one end of the splitter blade 81, which is close to the cavity 3121, is provided with an arc-shaped groove 811, and one end of the splitter blade 81, which is far away from the cavity 3121, is provided with an arc-shaped protrusion 812. When rainwater flows into the water conduit 311, part of the rainwater flows through the diversion piece 81, and when the rainwater contacts with the groove surface of the arc-shaped groove 811, the impact of the rainwater on the diversion piece 81 drives the diversion piece 81 to move so as to drive the diversion piece 8 to rotate; the rainwater is split into a plurality of trickles under the action of the splitter 81, and the trickles flow in a spiral shape to form vortex, so that the vortex can not only accelerate the flowing speed of the rainwater, but also has attractive force on the rainwater above, and the inflow of the rainwater staying on the roof body 1 can be accelerated; the rotating diversion piece 8 has strengthening effect on vortex formed after rainwater flows through, the speed of the rainwater flowing through the diversion piece 8 is increased, and the speed of the rainwater on the roof body 1 flowing into the water diversion pipe 311 is also increased; and, the arc-shaped protrusions 812 will exert a downward force on the rainwater flow flowing through the flow dividing member 8 during the rotation of the flow dividing member 8, thereby accelerating the flow rate of the rainwater flow.
In addition, when the rainwater flows into the arc-shaped groove 811 and impacts the groove surface of the arc-shaped groove 811, the whole water guiding member 312 is driven to move vertically downwards, so that the abutting portion 3125 further presses the waterproof layer 13, the deformation amount of the waterproof layer 13 is increased, and the rainwater on the roof body 1 also flows more easily in the direction approaching the water guiding member 312.
Since the rainwater on the waterproof layer 13 easily flows in the direction close to the water guiding member 312, the position of the waterproof layer 13 damaged by rainwater will also appear in the position close to the water guiding member 312, so that the repair area required after the waterproof layer 13 is damaged can be reduced, and the material is saved.
Referring to fig. 3 and 4, a plurality of blocking removing members 9 for cleaning the first water diversion holes 3122 are installed at one end of the rod body 7 close to the cavity 3121, the blocking removing members 9 are rotatably connected with the rod body 7, the rotation axis of the blocking removing members 9 is perpendicular to the axis of the rod body 7, the plurality of blocking removing members 9 are distributed on the rod body 7 in a circumferential array with the axis of the rod body 7 as an axis, and the plurality of blocking removing members 9 are in one-to-one correspondence with the plurality of first water diversion holes 3122.

The rotational connection between the block-removing member 9 and the rod body 7 has an angular limitation, and when the block-removing member 9 rotates to a limit position in a direction away from the rod body 7, the block-removing end penetrates out of the corresponding first water diversion hole 3122.
Referring to fig. 3 and 4, the blocking remover 9 is in an arc-shaped sheet structure, one end of the blocking remover 9, which is far away from the second elastic piece 10, is provided with a bending part 91, when the blocking remover 9 abuts against the rod body 7, the end surfaces of the blocking remover 9 abutting against the rod body 7 are mutually attached, at the moment, the bending part 91 is in an inclined state relative to the rod body 7, and one end of the bending part 91, which is close to the rod body 7, is an inclined lower end; when the block-removing member 9 is rotated to the limit state, the bending portion 91 is approximately in the horizontal state with respect to the rod body 7.
When the first water diversion holes 3122 are blocked, rainwater flows in from the second water diversion holes 3123, and part of rainwater forms impact on the bending part 91 in the rainwater inflow process, so that the blocking removing member 9 is driven to rotate towards the direction close to the first water diversion holes 3122 against the acting force of the second elastic member 10, and the blocking removing member 9 forms impact on the blocking removing member 9 after the blocking removing member 9 starts to rotate, so that the blocking removing member 9 further rotates; when the blocking removing member 9 rotates to the limit state, the blocking removing member 9 completes blocking removing of the corresponding first water diversion hole 3122, and when rainwater flows in from the first water diversion hole 3122, impact is formed on the blocking removing member 9 to drive the blocking removing member 9 to rotate and reset, and meanwhile, the inflow amount of the rainwater from the second water diversion hole 3123 is reduced, so that the blocking removing member 9 can smoothly rotate and retract under the drive of the second elastic member 10.
When the first water diversion holes 3122 are blocked, rainwater flows into the second water diversion holes 3123 after being accumulated, and for the blockage removing member 9 corresponding to the first water diversion holes 3122 which are not blocked, the sum of the impact of the rainwater flowing into the first water diversion holes 3122 on the blockage removing member 9 and the acting force of the second elastic member 10 is larger than the sum of the impact of the rainwater flowing into the second water diversion holes 3123 on the blockage removing member 9 and the gravity of the blockage removing member 9; and for the blocking remover 9 corresponding to the blocked first water diversion hole 3122, at this time, the sum of the impact of the rainwater flowing in from the second water diversion hole 3123 to the blocking remover 9 and the gravity of the blocking remover 9 is larger than the acting force of the second elastic member 10, so that the blocking remover 9 corresponding to the blocked first water diversion hole 3122 is driven to rotate to clear the first water diversion hole 3122.

Two ends of the seepage pipeline 33 are fixedly connected and communicated with the two water pipelines 32 through transition pipelines 34 respectively, and a plurality of seepage pipelines 33 are distributed on the seepage-proof concrete layer 12 in square arrays. A plurality of water seepage holes 331 for rainwater inflow are formed in one side of the water seepage pipeline 33, which is close to the waterproof layer 13, when the waterproof layer 13 is damaged, rainwater can enter the water seepage pipeline 33 through the water seepage holes 331 after penetrating into the impermeable concrete layer 12 through the waterproof layer 13, and the water leakage probability of the roof body 1 is reduced. After entering the water seepage pipe 33, the rainwater flows into the water pipeline 32 and then flows into the water drainage channel 2, and finally is discharged from the water drainage pipe 4.
When the rainwater enters the water pipe 32 and is discharged, there is still a part of rainwater remaining in the water pipe 32, and the remaining rainwater is mainly concentrated at the junction of the water pipe 32 and the transition pipe 34. At this time, when the outside is in a high temperature environment, the evaporation of the residual rainwater in the water pipe 32 will perform the function of heat dissipation and cooling on the whole roof body 1, so that the aging speed of the waterproof layer 13 due to the high temperature can be slowed down, and the inside of the house can be cooled more.
In this embodiment, the drain channel 2, the drain pipe 4, the water pipe 32, the water pipe 311, and the water seepage pipe 33 are made of a material which is not easily corroded by rainwater and has a good heat conduction effect, and in this embodiment, stainless steel is preferable.

the waterproof layer 13 and the impermeable concrete layer 12 can prevent rainwater from penetrating, so that the roof body 1 has a good waterproof effect;
when rainwater falls onto the roof body 1, part of the rainwater directly flows into the drainage channel 2 and is then discharged through the drainage pipe 4; another part of the rainwater enters the water diversion pipe 311 through the water diversion part 312, then flows into the water pipe 32, then flows into the water drainage channel 2, and finally is discharged through the water drainage pipe 4; the rest rainwater naturally evaporates; thereby reducing the time for the rainwater to stay on the roof body 1 and reducing the amount of the rainwater to stay on the roof body 1, and further improving the waterproof effect of the roof body 1.
The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
