However, in modern buildings, when it rains, most rainwater flows along the top of the house to the outside, and then flows to the drainage ditch for discharge. At present, most cities are facing water shortages. In the process of construction, the conscious development of rainwater collection and utilization projects has not only increased the total amount of available water resources, but also saved existing water resources.

[0003] A green building capable of utilizing rainwater as mentioned in an existing Chinese public patent (authorization announcement number: CN217811979U) comprises a main body of a house, roofs are fixedly installed on both sides of the upper end of the main body of the house, and a water guide trough is fixedly installed on one side of the roof, the water guide trough is in an inclined state, and the interior of the water guide trough is a rectangular structure, a filter box is fixedly installed on one side of the lower end of the water guide trough, and the water guide trough is connected to the filter box, a drain pipe is fixedly installed on the lower end of the filter box, and a filter screen is fixedly installed between the middle position of the roof and the other side of the water guide trough, and the water guide trough is conveniently drained to the interior of the filter box by adopting the water guide trough, and the rainwater is discharged through the drain pipe after being filtered, so that the rainwater is convenient to utilize, and through the scraper, after raining, the mud and dirt deposited in the water guide trough can be pushed to the interior of the drain pipe for discharge to avoid blockage, and through the solar cell panel, light energy can be conveniently utilized, which is green and energy-saving and easy to use.

[0004] In the above patent, a scraper is provided to push the mud and dirt deposited inside the water guide trough to the inside of the sewage pipe for discharge to avoid blockage.

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] The embodiment of the present application discloses a rainwater utilizing building structure.

[0035] Reference Figure 1 , Figure 2 and Figure 3 A rainwater utilization building structure comprises a building body 1, a building roof 2 is symmetrically arranged on the top of the building body 1, a water collecting tank 3 is fixedly connected to one side of the bottom of the building roof 2, a water collecting pipe 4 is fixedly connected to the bottom surface of one end of the water collecting tank 3, a sewage pipe 5 is fixedly connected to the bottom surface of the water collecting tank 3 away from the water collecting pipe 4, a filter plate 6 is fixedly connected to the water collecting tank 3, a cleaning component 8 is installed inside the water collecting tank 3, a water baffle 83 is slidably arranged inside the water collecting tank 3, an adjusting component is installed at the bottom of the water baffle 83, a waterproof box 9 is fixedly connected to one end of the water collecting tank 3, a battery 10 is fixedly connected to the inside of the waterproof box 9, a controller 11 is fixedly connected to the inside of the waterproof box 9, a baffle 12 is fixedly connected to the top of one end of the water collecting tank 3, a storage box 13 is fixedly connected to the bottom of the water collecting pipe 4, a guide inclined plate 7 is fixedly connected to the inside of the water collecting tank 3, and the guide inclined plate 7 is located below the filter plate 6, and all electrical appliances in the device are electrically connected to the controller 11.

[0036] When rainy weather comes, rainwater will be guided by the inclined surface of the building roof 2 and flow into the interior of the water collection tank 3, and then pass through the filter plate 6 for initial filtration to intercept some larger impurities such as leaves and soil. The filtered rainwater will be guided by the guide inclined plate 7 and flow into the interior of the storage box 13 through the water collection pipe 4, thereby completing the rainwater collection and waiting for subsequent use. After the filter plate 6 has been filtering for a long time, a large amount of debris will accumulate on the top of the filter plate 6, which may cause the filter plate 6 to be blocked and affect the filtering effect of the filter plate 6. At this time, the cleaning component 8 can be started to operate. Through the operation of the cleaning component 8, the surface of the filter plate 6 can be directly cleaned quickly, and then the debris can be pushed into the sewage pipe 5 for discharge. At the same time, the adjustment component can avoid pushing the debris on the filter plate 6 to the other side of the filter plate, resulting in the filter plate 6 being blocked after a long period of accumulation. The practicability of the device is effectively improved, and there is no need to manually climb to the roof for cleaning.

[0037] Reference Figure 2 and Figure 3 The cleaning assembly 8 includes a threaded rod 81 rotatably connected to the inside of the water collection tank 3, a motor 82 is fixedly connected to the inside of the waterproof box 9, the output end of the motor 82 passes through and is fixedly connected to the threaded rod 81, one end of the water baffle 83 is threadedly connected to the threaded rod 81, both sides of the water collection tank 3 are fixedly connected to pressure sensors 87, and a guide rod 84 is fixedly connected to the inside of the water collection tank 3, the guide rod 84 and the threaded rod 81 are parallel to each other, and one end of the water baffle 83 is slidably connected to the guide rod 84;

[0038] Secondly, the adjustment component includes an electric telescopic rod 85 symmetrically fixedly connected to both sides of the bottom of the water retaining plate 83, and the output end of the electric telescopic rod 85 is fixedly connected to a cleaning brush 86, and the bottom of the cleaning brush 86 is in contact with the top surface of the filter plate 6.

[0039] When in use, first start the electric telescopic rod 85 to drive the cleaning brush 86 to fit with the filter plate 6, and then drive the threaded rod 81 to rotate by the operation of the motor 82. When the threaded rod 81 rotates, the water baffle plate 83 will move on the threaded rod 81 under the guidance of the guide rod 84. The movement of the water baffle plate 83 will drive the cleaning brush 86 at the bottom to move together to clean the debris on the filter plate 6 until the debris is pushed to one end of the water collection tank 3 and falls into the sewage pipe 5 for discharge. When the water baffle plate 83 continues to move to the inner end of the water collection tank 3, one side of the water baffle plate 83 will touch the pressure sensor 87. At this time, the pressure sensor 87 transmits a signal to the controller 1 1, the electric telescopic rod 85 is started by the controller 11 to drive the cleaning brush 86 to gradually rise away from the top of the filter plate 6, and then the motor 82 is started to reverse and drive the water retaining plate 83 to return to the other end of the filter plate 6 until the water retaining plate 83 touches another pressure sensor 87. At this time, the electric telescopic rod 85 can be started to drive the cleaning brush 86 to fit the top of the filter plate 6 again, so that the device can clean the debris on the filter plate 6 while ensuring that the debris on the filter plate 6 will not be pushed to the other side of the filter plate, so as to avoid the accumulation of debris on one side of the filter plate 6 that cannot be cleaned and cause the filter plate 6 to be blocked, which effectively improves the practicality of the device and no longer needs to climb to the roof for cleaning.

[0040] Reference Figure 4 and Figure 5 A filter plate 2 131 is slidably arranged inside the storage box 13, a through groove is opened on one side of the storage box 13, a sealing strip 132 is fixedly connected inside the through groove, one end of the filter plate 2 131 is located in the sealing strip 132, a water outlet pipe 133 is fixedly connected to the bottom of the storage box 13, a valve is installed on the water outlet pipe 133, and limiting components are installed on both sides of the storage box 13, the limiting components include grooves 135 symmetrically opened on both sides of the storage box 13, a limiting block 136 is slidably connected inside the groove 135, a spring 137 is fixedly connected inside the groove 135, one end of the spring 137 is fixedly connected to one end of the limiting block 136, one end of the limiting block 136 is arc-shaped, and limiting grooves 134 with the same shape as the limiting block 136 are opened on both sides of the filter plate 2 131.

[0041] When in use, the filtered rainwater is guided by the guide inclined plate 7 and then flows into the interior of the storage box 13 through the water collecting pipe 4. At this time, the rainwater can be filtered again through the filter plate 131, and then the filtered rainwater is stored in the storage box 13. When the filtered rainwater needs to be used, the valve can be opened to process and store the rainwater through the outlet pipe 133, which greatly improves the green environmental protection effect of the building and better utilizes the rainwater. When the filter plate 131 needs to be cleaned, the filter plate 131 can be directly pulled out of the through groove for cleaning. Then, the cleaned filter plate 131 is reinserted into the through groove. At this time, the inner walls on both sides of the filter plate 131 will squeeze the limit block 136 into the groove 135 until the filter plate 131 is completely inserted into the storage box 13. At this time, the limit block 136 will be parallel to the limit groove 134, and the spring 137 will rebound to drive the limit block 136 into the limit groove 134, so as to fix the position of the filter plate 131 to prevent the filter plate 131 from loosening and falling off. At the same time, the through groove can be sealed by the sealing strip 132 to prevent rainwater from penetrating.

[0042] The implementation principle of a rainwater utilization building structure in this embodiment is as follows: when rainy weather comes, rainwater will be guided by the inclined surface of the building roof 2 and flow into the inside of the water collection tank 3, and then pass through the filter plate 1 6 for primary filtration to intercept some larger impurities such as leaves and soil. The filtered rainwater will be guided by the guide inclined plate 7 and flow into the inside of the storage box 13 through the water collection pipe 4. At this time, the rainwater can be filtered again through the filter plate 2 131, and then the filtered rainwater will be stored in the storage box 13. When the filtered rainwater is needed, the valve can be opened to process and store the rainwater through the outlet pipe 133, which greatly improves the green environmental protection effect of the building and better utilizes the rainwater for the second time. When cleaning the filter plate 131, the filter plate 131 can be directly pulled out from the through slot for cleaning, and then the cleaned filter plate 131 can be reinserted into the through slot. At this time, the inner walls of both sides of the filter plate 131 will squeeze the limit blocks 136 into the grooves 135 until the filter plate 131 is completely inserted into the storage box 13. At this time, the limit blocks 136 will be parallel to the limit slots 134, and the limit blocks 136 will be driven to enter the limit slots 134 through the rebound of the spring 137, so as to fix the position of the filter plate 131 to prevent the filter plate 131 from loosening and falling off. At the same time, the through slot can be sealed by the sealing strip 132 to prevent rainwater from penetrating, so as to complete the rainwater collection and wait for subsequent use.

[0043] Secondly, after the filter plate 6 has been filtering for a long time, a large amount of debris will accumulate on the top of the filter plate 6, which may cause the filter plate 6 to be blocked and affect the filtering effect of the filter plate 6. At this time, the electric telescopic rod 85 can be started to drive the cleaning brush 86 to fit with the filter plate 6, and then the motor 82 can be used to drive the threaded rod 81 to rotate. When the threaded rod 81 rotates, the water baffle plate 83 will move on the threaded rod 81 under the guidance of the guide rod 84. The movement of the water baffle plate 83 will drive the cleaning brush 86 at the bottom to move together to clean the debris on the filter plate 6 until the debris is pushed to one end of the water collection tank 3 and falls into the sewage pipe 5 for discharge. When the water baffle plate 83 continues to move to the inner end of the water collection tank 3, one side of the water baffle plate 83 will touch the pressure The pressure sensor 87 transmits a signal to the controller 11, which starts the electric telescopic rod 85 to drive the cleaning brush 86 to gradually rise away from the top of the filter plate 6. Then, the motor 82 is started to reverse and drive the water retaining plate 83 to return to the other end of the filter plate 6 until the water retaining plate 83 touches another pressure sensor 87. At this time, the electric telescopic rod 85 can be started to drive the cleaning brush 86 to fit the top of the filter plate 6 again, so that the device can clean the debris on the filter plate 6 while ensuring that the debris on the filter plate 6 will not be pushed to the other side of the filter plate, so as to avoid the accumulation of debris on one side of the filter plate 6 that cannot be cleaned and cause the filter plate 6 to be blocked, which effectively improves the practicality of the device and no longer needs to climb to the roof for cleaning.
