Technical Field

[0001] This utility model relates to the field of building rainwater harvesting technology, and in particular to an energy-saving device for collecting and utilizing rainwater on building roofs. Background Technology

[0002] Building roofs are often major rainwater collection points, which are usually discharged directly into the ground through drainage pipes. With the growing awareness of environmental protection, rainwater harvesting and utilization on building roofs has become an important direction for water and energy conservation.

[0003] Chinese patent document CN221798579U discloses a building rainwater harvesting structure, including a filter bucket. A bracket is fixedly connected to the bottom of the filter bucket, a water outlet pipe is fixedly connected to one end of the filter bucket, and a building drainage pipe is fixedly connected to the top of the filter bucket. A limiting frame is fixedly connected to one end of the filter bucket; a limiting component is slidably connected to the middle of the limiting frame, and the limiting component includes a connecting plate, a limiting plate, and a screw. Compared to existing technologies, this application avoids workers having to carry rainwater back and forth, reducing work steps and workload. Furthermore, the water outlet pipe can be adapted to various sizes of plastic water pipes, making it more practical.

[0004] When using the above-mentioned building rainwater harvesting structure, the filter screen and its surrounding structure need to be removed for cleaning. Since the rainwater discharged from the building usually contains a lot of impurities, repeated disassembly and cleaning is quite troublesome. Sometimes it is only a slight blockage, which increases the workload of the staff. Utility Model Content

[0005] The purpose of this utility model is to provide a rainwater collection and energy-saving device for building roofs, which can solve the problem that when the above-mentioned building rainwater collection structure is used, the filter screen and its surrounding structure need to be removed for cleaning. Since the rainwater discharged from the building usually contains a lot of impurities, repeated disassembly and cleaning is troublesome. Sometimes it is only a slight blockage, which increases the workload of the staff.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rainwater harvesting and energy-saving utilization device for building roofs, comprising a water storage tank, a water filtration mechanism, and a cleaning mechanism. The water filtration mechanism is located outside the water storage tank and includes a connecting box, an annular plate, and a fine filter screen. The connecting box is fixedly installed on the outer wall of the water storage tank, and the inner wall of the connecting box is fixedly connected to the outer walls of two sets of annular plates. Fine filter screens are fixedly installed on adjacent sides of the two sets of annular plates. The cleaning mechanism is located outside the water storage tank and includes a rotating rod, an mounting rod, and cleaning brushes. The outer wall of the rotating rod is fixedly connected to one end of multiple sets of mounting rods, and two sets of cleaning brushes are fixedly installed on the other end of the mounting rods.

The water injection pipe is located between two sets of annular plates. A drain pipe is fixedly installed at the bottom of the connecting box, and a sealing cap is threaded onto one end of the drain pipe. This allows for the filtration of impurities in the sewage discharged from the building roof, followed by the collection of rainwater. This facilitates the direct use of rainwater and avoids clogging of components such as water pumps and pipes, while also allowing for the rapid discharge of filtered impurities and sewage.

[0008] Preferably, the cleaning mechanism further includes a snap-fit ​​cover and a handle. The snap-fit ​​cover is snap-fitted onto the top of the connecting box, and a rotating rod is rotatably mounted on the inner top of the snap-fit ​​cover. One end of the rotating rod passes through the snap-fit ​​cover and is fixedly mounted with a handle. This allows the fine filter cylinder to be brushed and cleaned with the help of rainwater, without having to remove the fine filter cylinder. This ensures smooth filtration of rainwater, reduces the workload of workers, and the entire device does not require electrical equipment to drive it, resulting in lower production costs and making it more energy-efficient and environmentally friendly.

[0018] Please see Figure 1-3 This utility model provides a technical solution: a rainwater harvesting and energy-saving device for building roofs, comprising a water storage tank 1, a water filtration mechanism 2, and a cleaning mechanism 3. The water filtration mechanism 2 is located outside the water storage tank 1 and includes a connecting box 201, an annular plate 202, and a fine filter screen 203. The connecting box 201 is fixedly installed on the outer wall of the water storage tank 1, and the inner wall of the connecting box 201 is fixedly connected to the outer walls of two sets of annular plates 202. Fine filter screens 203 are fixedly installed on adjacent sides of the two sets of annular plates 202. The cleaning mechanism 3 is located outside the water storage tank 1 and includes a rotating rod 302, an mounting rod 303, and a cleaning mechanism 3. The cleaning brush 304 and the outer wall of the rotating rod 302 are fixedly connected to one end of multiple sets of mounting rods 303. Two sets of cleaning brushes 304 are fixedly installed on the other end of the mounting rods 303. The cleaning brushes 304 are in contact with but not connected to the inner wall of the fine filter cylinder 203. An auxiliary handle is provided at the bottom of the sealing cover 205. A water inlet pipe 4 is fixedly installed on the outer wall of the connecting box 201 and is connected to it. The water inlet pipe 4 is located above the annular plate 202. A drain pipe 6 is fixedly installed on the outer wall of the water storage tank 1. The drain pipe 6 is connected to the inside of the water storage tank 1 and a control valve 7 is provided on the drain pipe 6. A capacity window 5 is embedded in the outer wall of the water storage tank 1.

[0019] Secondly, the water filtration mechanism 2 also includes a sewage pipe 204, a sealing cap 205, and a water injection pipe 206. The outer wall of the connecting box 201 is fixedly connected to one end of the water injection pipe 206 and they are in communication. The other end of the water injection pipe 206 is fixedly connected to the outer wall of the water storage tank 1 and they are in communication. The water injection pipe 206 is located between two sets of annular plates 202. The sewage pipe 204 is fixedly installed at the bottom of the connecting box 201. A sealing cap 205 is threaded onto one end of the sewage pipe 204.

[0021] Working principle: When using this device, the inlet pipe 4 is connected to the building drainage pipe via a flange. Rainwater first flows into the connecting box 201 through the inlet pipe 4. Impurities in the rainwater are intercepted by the inner wall of the drain pipe 204. The filtered water flows into the storage tank 1 through the injection pipe 206. The water level in the storage tank 1 can be observed through the capacity window 5. The water pump pipe is connected to the drain pipe 6, and the control valve 7 is opened to pump out the rainwater stored in the storage tank 1. This water can then be used for watering plants, etc. When the fine filter cylinder 2... 03 When filtration is obstructed, hold the handle 305 and rotate the rotating rod 302 to rotate the mounting rod 303, which in turn rotates the cleaning brush 304. This, combined with the rainwater flushing, brushes the inner wall of the fine filter cylinder 203 to remove the blockage. After the rain stops, remove the sealing cover 205 from the drain pipe 204 to allow the sewage and impurities in the connecting box 201 to be discharged through the drain pipe 204. Remove the snap-fit ​​cover 301 and take out the cleaning brush 304 for cleaning and replacement.

[0022] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings.
