Technical Field

[0001] The present application relates to the field of roof technology, and in particular to an energy-saving building roof structure. Background Art

[0002] The roof, the rooftop of a house, consists of a sloping rooftop and gutters at the eaves. Downward-extending drainage pipes run through the bottom of the gutters. Rainwater flows through the sloping rooftop into the gutters, where it is then discharged downward through the drainage pipes.

[0003] Due to the presence of debris such as fallen leaves, the drainage pipes in the gutter are easily clogged by debris after a period of time, affecting the drainage efficiency of the gutter and drainage pipes. Summary of the Invention

[0004] In order to improve the problem that drainage pipes are easily blocked, the present application provides an energy-saving building roof structure.

[0005] This application provides an energy-saving building roof structure, which adopts the following technical solutions:

[0006] An energy-saving building roof structure includes a roof body and a drainage assembly arranged at the eaves of the roof body; the drainage assembly includes:

[0007] The water collecting cylinder is fixed horizontally under the eaves. The water collecting cylinder has an axially extending water collecting cavity. The upper end of the water collecting cylinder is provided with a water inlet communicating with the water collecting cavity. The lower end of the water collecting cylinder is provided with a sewage outlet communicating with the water collecting cavity.

[0008] The water collecting roller is coaxially connected to the water collecting cavity of the water collecting cylinder. The water collecting roller is provided with a plurality of receiving grooves for communicating with the water inlet or the sewage outlet. The receiving grooves pass through both ends of the axial direction of the water collecting roller.

[0009] A water collecting box with an opening is arranged in the receiving tank, and the opening of the water collecting box faces a side away from the receiving tank;

[0010] Wherein, coaxial guide posts are fixed to the bottoms of both ends of the length direction of the water collecting box, and a guide ring groove coaxial with the water collecting box is provided on the inner wall of the water collecting cylinder, and the guide post is located in the guide ring groove; the water collecting cylinder is also provided with a vertical groove connected with the guide ring groove at the water inlet for allowing the guide post to move upward; an elastic member for driving the water collecting box to move toward the vertical groove is provided in the accommodating groove; when the guide post is located in the vertical groove away from the end of the guide ring groove, the water collecting box extends out of the water inlet and is in a water collecting state state; both sides of the water collecting cylinder are connected with drainage pipes connected with the vertical grooves, and the guide column axially penetrates to form a drainage hole connected with the water collecting box; when the water collecting box is in the water collecting state, the drainage hole is connected with the drainage pipe; the water collecting box is provided with a filter screen at the drainage hole; the accumulated water caused by the blockage of the water collecting box can overcome the elastic force of the elastic part, so that the water collecting box is retracted into the water collecting cylinder, and the guide column is located in the guide ring groove; the drainage assembly also includes a driving member for driving the water collecting roller to rotate when the guide column is located in the guide ring groove.

[0011] By adopting the above technical solution, when debris falls into the water collecting box and blocks the filter screen, water begins to accumulate in the water collecting box. The water collecting box uses the accumulated water to overcome the elastic force of the elastic part, so that the guide column enters the guide ring groove from the vertical groove. The driving part drives the water collecting roller to rotate, so that the adjacent water collecting box is located at the water inlet. In this way, the original blocked water collecting box can be replaced to collect water again, and the water collecting box with garbage will move to the sewage outlet with the water collecting roller, so that the debris is discharged from the sewage outlet under the action of its own gravity, reducing the garbage in the water collecting box, thereby improving the drainage efficiency. The process only requires the help of accumulated water, which has an energy-saving effect.

[0012] Optionally, the driving member includes a counterweight block, and a rotating shaft rotatably connected to the water collecting drum is coaxially fixed to both ends of the water collecting roller, and a winding wheel is coaxially fixed to one end of the rotating shaft extending outside the water collecting drum, a pull rope is wound on the winding wheel, and the counterweight block is fixedly connected to the end of the pull rope.

[0013] By adopting the above technical solution, when the guide columns of all water collecting boxes are located in the guide ring groove, the counterweight block pulls the pull rope downward, causing the winding wheel to rotate with the water collecting roller, thereby realizing the switching of the water collecting box position.

[0014] Optionally, the water collecting box is further provided with a cleaning component for discharging debris in the water collecting box out of the sewage outlet.

[0015] By adopting the above technical solution and setting up the cleaning component, the garbage in the water collection box can be further cleaned.

[0016] Optionally, the cleaning assembly includes a scraper located in the water collecting box, and the scraper can move up and down in a direction close to or away from the bottom of the water collecting box.

[0017] By adopting the above technical solution, when the water collecting box is located at the sewage outlet, the scraper will move toward the sewage outlet under the action of its own gravity, thereby pushing the debris in the water collecting box out of the water collecting box, thereby cleaning the debris in the water collecting box.

[0018] Optionally, a guide rod extending toward the moving direction of the scraper is fixed to the bottom of the water collecting box, a guide hole for the guide rod to pass through is opened on the scraper, the guide rod is passed through the guide hole, and a limit block is provided at the end of the guide rod away from the bottom of the water collecting box to prevent the scraper from detaching from the guide rod.

[0019] By adopting the above technical solution and arranging the limit block and the guide rod, the scraper in the water collecting box can move along the track of the guide rod while preventing the scraper from leaving the water collecting box.

[0020] Optionally, the water collecting cylinder is provided with a plurality of magnetic strips at the sewage outlet, and the scraper is a magnet that cooperates with the magnetic strips.

[0021] By adopting the above technical solution, the provision of the magnetic strip can speed up the movement of the scraper toward the sewage outlet, thereby achieving further cleaning of debris in the water collecting box.

[0035] The present application is further described in detail below with reference to the accompanying drawings.

[0036] The embodiment of the present application discloses an energy-saving building roof structure. Figure 1 The building roof structure includes a roof body 1 and a drainage assembly installed at the eaves. The roof body 1 is a roof structure that slopes downward from the middle to both sides. The drainage assembly is used to collect rainwater flowing in the direction of the roof body 1.

[0037] Reference Figure 2 、 3 The drainage assembly includes a water collection drum 2, a water collection roller 3, and a water collection box 4. The water collection drum 2 is fixedly mounted horizontally at the eaves. Specifically, a connecting rod 5 is fixed to the side of the water collection drum 2, one end of which is bolted to the wall below the roof body 1. The water collection drum 2 has an axially extending water collection cavity 6. The upper end of the water collection drum 2 is provided with a water inlet 7 connected to the water collection cavity 6, and the lower end of the water collection drum 2 is provided with a sewage outlet 8 connected to the water collection cavity 6.

[0038] The water collection roller 3 is a cylindrical structure that fits within the water collection cavity 6 and is rotatably connected to the water collection cavity 6 of the water collection drum 2. Specifically, a rotating shaft 9 is coaxially welded to each end of the water collection roller 3, forming a rotational connection with the water collection drum 2 via the rotating shaft 9. The water collection roller 3 is provided with multiple receiving slots 10 for mounting the water collection box 4. The receiving slots 10 extend axially through both ends of the water collection roller 3. This embodiment uses four receiving slots 10 as an example for illustration. The four receiving slots 10 are evenly spaced around the circumference of the water collection roller 3. When one receiving slot 10 is aligned with the water inlet 7, the other receiving slot 10 is aligned with the sewage outlet 8.

[0039] Reference Figure 2 、 3 The water collecting box 4 has an opening on one side. When the water collecting box 4 is installed in the receiving groove 10, the opening of the water collecting box 4 faces the water collecting tube 2. Guide columns 11 are welded to the bottom of both ends of the water collecting box 4 in the longitudinal direction. The guide columns 11 are parallel to the axis of the water collecting tube 2. A guide ring groove 12 coaxial with the water collecting tube 2 is provided on the inner wall of the water collecting tube 2, and the guide column 11 is located in the guide ring groove 12. A vertical groove 13 connected to the guide ring groove 12 is also provided on the inner wall of the water collecting tube 2 at the water inlet 7. The guide column 11 can enter the vertical groove 13 and slide down along the direction of the vertical groove 13.

[0040] Reference Figure 4 When the guide post 11 is located in the guide ring groove 12, the water collection box 4 is located in the receiving groove 10. When the guide post 11 enters the vertical groove 13, the water collection box 4 is aligned with the water inlet 7. At this time, the guide post 11 can move upward along the vertical groove 13 and cause the water collection box 4 to extend out of the water inlet 7, thus collecting water.

[0041] Reference Figure 4 , an elastic member is also provided in the receiving groove 10, and the elastic member is used to drive the water collecting box 4 to move in a direction away from the receiving groove 10. The specific elastic member includes a spring 14, which is installed at the bottom of the receiving groove 10. One end of the spring 14 is fixedly connected to the receiving groove 10, and the other end is fixedly connected to the bottom of the water collecting box 4. In the absence of external force, when the guide column 11 moves to the vertical groove 13, the spring 14 can drive the water collecting box 4 to extend outward toward the water inlet 7, so that the guide column 11 enters the vertical groove 13 and is located at the end of the vertical groove 13 away from the guide ring groove 12. In order to increase the stability of the water collecting box 4 when it moves upward, a plurality of springs 14 are provided, and the plurality of springs 14 are evenly spaced along the length direction of the receiving groove 10.

[0042] Reference Figure 2 、 3 Drain pipes 15 are fixedly mounted at both ends of the water collection tube 2 and communicate with the vertical groove 13. A drainage hole 16 is formed through the guide column 11 and communicates with the water collection box 4. A filter 17 is installed in the water collection box 4 at the drainage hole 16 to prevent debris from entering the drainage hole 16. When the water collection box 4 is in the water collection state, that is, when the guide column 11 is located at the end of the vertical groove 13 away from the guide ring groove 12, the drainage hole 16 of the guide column 11 is connected to the drainage pipe 15. When rainwater enters the water collection box 4, it is discharged through the drainage hole 16 and the drainage pipe 15.

[0043] Reference Figure 5The drainage assembly also includes a driving member. When the guide column 11 of the water collecting box 4 at the water inlet 7 falls back into the guide ring groove 12, the driving member can drive the water collecting roller 3 to rotate, so that the adjacent water collecting box 4 reaches the position of the water inlet 7 and extends out of the water inlet 7 under the action of the spring 14.

[0044] Specifically, the driving component includes a counterweight block 18, one end of the rotating shaft 9 on the water collecting roller 3 extends out of the water collecting drum 2, and the end of the rotating shaft 9 extending out of the water collecting drum 2 is welded and fixed with a winding wheel 20, and a pull rope 19 is wound around the winding wheel 20, and one end of the counterweight block 18 is fixedly connected to the pull rope 19.

[0045] When the filter screen 17 in the water collection box 4 is clogged, rainwater flowing into the water collection box 4 will accumulate in the water collection box 4, causing the weight of the water collection box 4 to continue to increase. The water collection box 4 with accumulated water can overcome the elastic force of the spring 14, causing the water collection box 4 to move toward the receiving groove 10 and causing the guide post 11 to fall back into the guide ring groove 12. When the guide post 11 of the water collection box 4 at the water inlet 7 falls back into the guide ring groove 12, the counterweight 18 pulls the downward pull rope 19, causing the reel 20 to rotate and drive the water collection roller 3, causing the adjacent water collection box 4 to reach the water inlet 7. At this time, the water collection box 4, under the action of the spring 14, extends out of the water inlet 7 to collect water, and at the same time, the water collection roller 3 is locked.

[0046] Reference Figure 4 、 5 To clean debris that clogs the filter screen 17 inside the water collection box 4, a cleaning assembly is installed inside the water collection box 4. Specifically, the cleaning assembly includes a scraper 21, which is located inside the water collection box 4, with its circumference abutting against the sidewalls of the water collection box 4. Two guide rods 22 extending perpendicular to the axis of the water collection roller 3 are welded to the bottom of the water collection box 4. The scraper 21 is provided with guide holes 23 that mate with the guide rods 22. The guide holes 23 on the scraper 21 are inserted through the guide rods 22, allowing the scraper 21 to move along the axis of the guide rods 22. When the water collection box 4 is facing the sewage outlet 8, the scraper 21 inside the water collection box 4 moves toward the sewage outlet 8 under the action of its own gravity, pushing debris attached to the water collection box 4 out of the water collection box 4 and out through the sewage outlet 8. When the water collection box 4 is located at the water inlet 7, the scraper 21 falls back to the bottom of the water collection box 4 under the action of its own gravity.

[0047] Reference Figure 6 In order to prevent the scraper 21 from separating from the water collecting box 4, a limiting block 24 is fixed at one end of the guide rod 22 away from the bottom of the water collecting box 4, and the area of the limiting block 24 is larger than the diameter of the guide hole 23.

[0048] Reference Figure 4The water collection drum 2 has a number of magnetic strips 25 arranged at intervals near the drain outlet 8. The scraper 21 is a magnet that magnetically cooperates with the magnetic strips 25. When the water collection box 4 is located at the drain outlet 8, the scraper 21 inside the water collection box 4 moves faster toward the drain outlet 8 under the suction of the magnetic strips 25, further discharging the debris in the water collection box 4 through the drain outlet 8.

[0049] The implementation principle of an energy-saving building roof structure in the embodiment of the present application is as follows:

[0050] Adjust one of the water collection boxes 4 to the water inlet 7 so that it extends out of the water inlet 7 to collect water under the action of the spring 14. When the filter screen 17 in the water collection box 4 is clogged and water accumulates in the water collection box 4, the water collection box 4 with the accumulated water can overcome the elastic force of the spring 14, causing the guide column 11 to enter the guide ring groove 12. At this time, the counterweight block 18 falls and drives the water collection roller 3 to rotate, causing the adjacent water collection box 4 to rotate to the water inlet 7 and extend out of the water inlet 7 to collect water. In the water collection box 4 located at the sewage outlet 8, the scraper 21 inside it moves towards the sewage outlet 8 under the action of its own gravity and the suction force of the magnetic strip 25, pushing the debris accumulated in the water collection box 4 out of the water collection box 4.

[0051] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
