One end of the rod body 7, which is far away from the cavity 3121, is rotatably connected with a flow dividing piece 8 with a flow dividing function, the rotating axis of the flow dividing piece 8 is superposed with the axis of the rod body 7, and the flow dividing piece 8 is positioned in the water conduit 311. The flow dividing member 8 comprises a plurality of flow dividing plates 81, the flow dividing plates 81 are of arc-shaped sheet structures, an arc-shaped groove 811 is arranged at one end of the flow dividing plate 81 close to the cavity 3121, and an arc-shaped protrusion 812 is arranged at one end of the flow dividing plate 81 far from the cavity 3121. When rainwater flows into the water conduit 311, part of the rainwater flows through the splitter 81, and when the rainwater contacts with the groove surface of the arc groove 811, the impact of the rainwater on the splitter 81 drives the splitter 81 to move so as to drive the splitter 8 to rotate; the rainwater is divided into a plurality of strands of thin flows under the action of the dividing sheet 81, the plurality of strands of thin flows flow in a spiral shape to form a vortex, the vortex can accelerate the flowing speed of the rainwater, meanwhile, the vortex has attraction to the rainwater above, and the inflow of the rainwater staying on the roof body 1 can be accelerated; the rotating flow dividing member 8 has a strengthening effect on the vortex formed after the rainwater flows through, the speed of the rainwater flowing through the flow dividing member 8 is increased, and the speed of the rainwater on the roof body 1 flowing into the water conduit 311 is also increased; moreover, the arc-shaped protrusion 812 applies a downward acting force to rainwater flowing through the splitter 8 in the process of rotating the splitter 8, so as to accelerate the flow rate of the rainwater.
In addition, when rainwater flows into the arc-shaped groove 811 and impacts the groove surface of the arc-shaped groove 811, the whole water diversion piece 312 is driven to move vertically and downwards, so that the abutting part 3125 further presses the waterproof layer 13, the deformation amount of the waterproof layer 13 is increased, and rainwater on the roof body 1 can flow towards the direction close to the water diversion piece 312 more easily.
Since the rainwater on the waterproof layer 13 easily flows toward the direction close to the water diversion member 312, the position of the waterproof layer 13 damaged by the erosion of the rainwater is concentrated at the position close to the water diversion member 312, the area required to be repaired after the waterproof layer 13 is damaged can be reduced, and the material is saved.
Referring to fig. 3 and 4, a plurality of blockage clearing members 9 for clearing the first water diversion holes 3122 are installed at one end of the rod body 7 close to the cavity 3121, the blockage clearing members 9 are rotatably connected with the rod body 7, a rotation axis of the blockage clearing members 9 is perpendicular to an axis of the rod body 7, the blockage clearing members 9 are circumferentially distributed on the rod body 7 in an array manner by taking the axis of the rod body 7 as an axis, and the blockage clearing members 9 correspond to the first water diversion holes 3122 one by one.
One end of the blockage removing part 9 in the length direction is rotatably connected with the rod body 7 through a second elastic part 10, the rotating connection position of the blockage removing part 9 and the rod body 7 is lower than the first water diversion hole 3122, the second elastic part 10 drives the blockage removing part 9 to be kept against the rod body 7, and at the moment, the second elastic part 10 is located at the lower end of the blockage removing part 9, and in the embodiment, the second elastic part 10 is preferably a torsion spring. The rotating connection between the blockage removing piece 9 and the rod body 7 has angle limitation, and when the blockage removing piece 9 rotates to the limit position in the direction far away from the rod body 7, the blockage removing end penetrates out of the corresponding first water diversion hole 3122.
Referring to fig. 3 and 4, the whole blockage clearing piece 9 is of an arc-shaped sheet structure, one end of the blockage clearing piece 9, which is far away from the second elastic piece 10, is provided with a bent part 91, when the blockage clearing piece 9 abuts against the rod body 7, the end faces of the blockage clearing piece 9, which abuts against the rod body 7, are mutually attached, at this time, the bent part 91 is in an inclined state relative to the rod body 7, and one end, which is close to the rod body 7, of the bent part 91 is an inclined lower end; when the blockage removing piece 9 rotates to the limit state, the bending part 91 is approximately in the horizontal state relative to the rod body 7.
When the plurality of first water diversion holes 3122 are blocked, rainwater flows in from the second water diversion holes 3123, and during the inflow process of rainwater, part of rainwater will impact the bent part 91, so as to drive the blockage clearing member 9 to rotate in the direction close to the first water diversion holes 3122 against the acting force of the second elastic member 10, and after the blockage clearing member 9 starts to rotate, rainwater will impact the blockage clearing member 9 integrally, so that the blockage clearing member 9 further rotates; when the blockage clearing piece 9 rotates to the limit state, the blockage clearing piece 9 clears the corresponding first water diversion hole 3122, when rainwater flows in from the first water diversion hole 3122, the blockage clearing piece 9 is impacted to drive the blockage clearing piece 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 blockage clearing piece 9 can smoothly rotate and retract under the drive of the second elastic piece 10.
When the first water diversion holes 3122 are blocked in the plurality of first water diversion holes 3122, rainwater flows in from the second water diversion holes 3123 after accumulating, for the clear-blocking member 9 corresponding to the unblocked first water diversion holes 3122, the sum of the impact of rainwater flowing in from the first water diversion holes 3122 on the clear-blocking member 9 and the acting force of the second elastic member 10 is greater than the sum of the impact of rainwater flowing in from the second water diversion holes 3123 on the clear-blocking member 9 and the gravity of the clear-blocking member 9; and for the blockage clearing member 9 corresponding to the blocked first water diversion hole 3122, the sum of the impact of rainwater flowing in from the second water diversion hole 3123 to the blockage clearing member 9 and the gravity of the blockage clearing member 9 is greater than the acting force of the second elastic member 10, so that the blockage clearing member 9 corresponding to the blocked first water diversion hole 3122 is driven to rotate to clear the blockage of the first water diversion hole 3122.
Referring to fig. 2 and 5, the drainage system 3 further includes a plurality of water permeable pipes 33, the plurality of water permeable pipes 33 are also embedded in the impermeable concrete layer 12, and the positions of the plurality of water permeable pipes 33 in the impermeable concrete layer 12 are all higher than the positions of the water through pipes 32. Two ends of the water seepage pipeline 33 are fixedly connected and communicated with the two water through pipelines 32 through transition pipelines 34 respectively, and the water seepage pipelines 33 are also distributed on the impermeable concrete layer 12 in a square array. When the waterproof layer 13 is damaged, the rainwater can enter the water seepage pipe 33 through the water seepage holes 331 after permeating into the impermeable concrete layer 12 through the waterproof layer 13, so as to reduce the probability of water leakage of the roof body 1. The rainwater enters the water seepage pipe 33, flows into the water passage pipe 32, flows into the drainage channel 2, and is finally discharged from the drainage pipe 4.
When the rainwater enters the water pipeline 32 and is discharged, a part of the rainwater still remains in the water pipeline 32, and the remaining rainwater is mainly concentrated at the boundary position of the water pipeline 32 and the transition pipeline 34. At this time, when the outside is in a high temperature environment, the rainwater remaining in the water pipeline 32 evaporates to perform the heat dissipation and cooling functions on the whole roof body 1, so that the aging speed of the waterproof layer 13 due to high temperature can be reduced, and the room can be made cooler.
In this embodiment, the drainage channel 2, the drainage pipe 4, the water passage 32, the water conduit 311, and the water seepage pipe 33 are made of a material that is not easily corroded by rainwater and has a good heat conduction effect.
The implementation principle of a roof waterproof engineering structure in the embodiment of the application is as follows:
the waterproof layer 13 and the impermeable concrete layer 12 can prevent rainwater from permeating, so that the roof body 1 has a good waterproof effect;
when the rainwater falls on the roof body 1, part of the rainwater directly flows into the drainage channel 2 and is drained through the drainage pipe 4; another part of the rainwater will enter the water conduit 311 through the water diversion member 312, then flow into the water pipeline 32, then flow into the drainage channel 2, and finally be discharged through the drainage pipe 4; the residual rainwater will evaporate naturally; thereby reducing the time of the rainwater staying on the roof body 1 and reducing the amount of the rainwater staying on the roof body 1, and further improving the waterproof effect of the roof body 1.
The above are preferred embodiments of the present application, and the scope of protection of the present application is not limited thereto, so: equivalent changes in structure, shape and principle of the present application shall be covered by the protection scope of the present application.
