[0002] Roof drainage refers to the measure of quickly draining rain and snow water from the roof through the water diversion device on the roof to avoid water accumulation in the roof area. It is usually done by opening grooves to collect rainwater, and then diverting rainwater to the ground drainage system through water diversion devices such as drain outlets and drainage pipes;
[0003] However, the drainage pipes in the existing roof drainage structure are used in the open air, and long-term use may easily cause the drainage pipes to be blocked by garbage from the outside, thereby affecting the normal discharge of water flow inside the gutter by the drainage pipes. Utility Model Content

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0023] like Figure 1-4 As shown, a building roof drainage structure for building construction engineering includes a drainage pipe 1, a filter screen 2 is fixedly installed on the top of the drainage pipe 1, and an anti-blocking structure 3 is arranged on one side of the surface of the drainage pipe 1;
[0024] The anti-blocking structure 3 includes a branch pipe 4, which is fixedly connected to one side surface of the drainage pipe 1. A fixing frame 5 is fixedly installed in the branch pipe 4, and a connecting rod 6 is slidably installed through the fixing frame 5. A floating plate 8 is fixedly installed on the top of the connecting rod 6, and a filter screen 7 is fixedly installed on the bottom end of the floating plate 8 close to the surface.
[0025] In this embodiment, the diameter of the floating plate 8 is larger than the diameter of the drainage pipe 1 , and the outer diameter of the filter screen 7 is the same as the inner diameter of the branch pipe 4 .
[0026] The floating plate 8 can be lifted by the buoyancy of water and can shield the drain pipe 1 when not in use. The filter screen 7 can be closely attached to the inner wall of the branch pipe 4 to prevent impurities from entering the drain pipe 1 through the gap between the two.
[0027] In this embodiment, the top end of the branch pipe 4 is higher than the top end of the drain pipe 1, and the cross section of the connecting rod 6 is a "T"-shaped structure.
[0028] The height of the branch pipe 4 is relatively high so that when the filter screen 2 is not blocked, it will not interfere with the operation of the drain pipe 1. The "T"-shaped structure plays a limiting role to prevent the floating plate 8 from separating from the branch pipe 4.
[0029] In this embodiment, the center of the fixing frame 5 is a circular ring structure, which is fixedly connected to the inner wall of the branch pipe 4 through a plurality of round rods.
[0030] The structure of the fixing frame 5 allows rainwater to be discharged through the gap between the circular ring and the circular rod in the fixing frame 5 , without affecting the drainage effect of the branch pipe 4 on rainwater.
[0031] In this embodiment, a vortex structure 9 is arranged inside the drain pipe 1 near the top, and the vortex structure 9 includes a baffle 10. The baffle 10 is fixedly installed inside the drain pipe 1, and a vortex tube 11 is fixedly installed at the bottom center of the baffle 10. The inner wall of the vortex tube 11 has four fixedly connected vortex blades 12.
[0032] The vortex structure 9 causes rainwater to form a vortex at the top of the drain pipe 1 when it is discharged, so that the rainwater is not easily blocked when it is discharged and the drainage effect is better.
[0033] In this embodiment, the vortex tube 11 is a truncated cone structure with a large upper opening and a small lower opening.
[0034] The structure of the vortex tube 11 can gather rainwater, thereby increasing the flow rate of rainwater, thereby facilitating the rainwater to rotate and form a vortex.
[0035] In this embodiment, four vortex blades 12 are evenly distributed on the inner wall of the vortex tube 11 , and the baffle 10 is connected to the vortex tube 11 .
[0036] The vortex blades 12 make the rainwater rotate along the direction of the vortex blades 12 when flowing through. The uniform distribution of multiple vortex blades 12 allows the rainwater to generate vortexes. The baffle 10 and the vortex tube 11 play a role in gathering the rainwater.
[0037] It should be noted that the utility model is a building roof drainage structure for building construction projects. When in use, rainwater will enter the interior of the drainage pipe 1 through the filter screen 2, and through the shielding of the baffle 10, the rainwater will enter through the top of the vortex tube 11. Since the vortex tube 11 is a structure with a large upper opening and a small lower opening, the rainwater will rotate along the spiral direction of the vortex blades 12 on the inner wall of the vortex tube 11, thereby forming a vortex, which can effectively avoid the blockage of the filter screen 2 and accelerate the discharge of rainwater.
[0038] When the filter screen 2 is clogged by larger impurities, rainwater accumulates, causing the floating plate 8 to float under the action of water buoyancy, and the rainwater will enter the branch pipe 4 through the filter screen 2 7 and be discharged, effectively preventing rainwater from accumulating and overflowing outside the roof. The connecting rod 6 and the fixing frame 5 play a limiting role, which can prevent the floating plate 8 and the filter screen 2 7 from detaching from the branch pipe 4.
[0039] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
