Description

Technical Field

[0001] This utility model relates to the field of rainwater harvesting technology, and in particular to a rainwater harvesting and utilization device for green building roofs. Background Technology

[0002] With the promotion of green buildings, rooftop greening is becoming increasingly popular, but this also brings new challenges to rainwater harvesting. Traditional rainwater harvesting systems typically rely on gravity flow or simple filter screens. However, rainwater from green building roofs often contains impurities such as silt, plant debris, etc., which can easily clog filters or pipes, leading to reduced harvesting efficiency or even system failure. Furthermore, passive harvesting structures are difficult to adapt to the complex roof environment, and cannot effectively divert rainwater when initial rainwater pollution is severe, affecting water quality.

[0003] In existing technologies, some improved solutions employ multi-stage filtration or sedimentation tank structures, but they still rely on passive drainage and cannot actively adapt to roof rainwater with high impurity content. A few pump-suction recycling devices suffer from high energy consumption and complex structures, making them difficult to integrate efficiently with green building roofs. Utility Model Content

[0004] The main purpose of this utility model is to provide a green building roof rainwater recycling device, which aims to improve the efficiency of rainwater recycling and ensure the stability of rainwater recycling.

[0005] To achieve the above objectives, this utility model proposes a green building roof rainwater recycling device, which includes a water tank, a recycling mechanism located at one end of the water tank, and a drainage mechanism located at the other end of the water tank. The recycling mechanism has a shell connected to the water tank. The shell facing the water tank has a filter section with a first filter screen installed, and the end of the shell away from the filter section has a liquid collection section with a second filter screen installed.

[0006] The housing is rotatably connected to a collection structure consisting of multiple scrapers connected to the inner wall of the housing. Adjacent scrapers and the inner wall of the housing are sandwiched to form a segmented cavity. A pressure regulating structure is provided on one side of the housing along the rotation direction of the collection structure toward the segmented cavity.

[0007] In one embodiment of this application, the scraper is provided with a reinforcing part connected to the inner wall of the housing along the side opposite to the rotation direction of the collecting structure.

[0008] In one embodiment of this application, the housing is provided with an opening relative to the pressure regulating structure, and the pressure regulating structure is provided with a guide portion disposed along the extension direction of the reinforcing portion relative to the opening portion, and a pressure regulating component is connected to the end of the guide portion away from the opening portion.

[0009] The length of the outer periphery of the reinforcing part is less than the length of the outer periphery of the open part.

[0010] In one embodiment of this application, the rotating shaft of the collecting structure passes through the housing and is connected to a reduction gear set. One end of the reduction gear set is provided with a reduction end connected to the collecting structure, and the other end is provided with a power generation end connected to a generator.

[0011] In one embodiment of this application, a third filter screen is provided in the water tank relative to the filtration section, and an activated carbon layer is provided on the side of the third filter screen opposite to the shell relative to the drainage mechanism, and the drainage mechanism is connected to the activated carbon layer.

[0012] In one embodiment of this application, the drainage mechanism includes a tee pipe connected to a water tank and a drain pipe located at the end of the tee pipe away from the water tank. The tee pipe has an installation part for installing an inlet water pipe between the water tank and the drain pipe.

[0013] In one embodiment of this application, a slag collection section is provided at the end of the housing away from the pressure regulating structure, and the pressure regulating structure, the filter section and the slag collection section are arranged sequentially along the rotation direction of the collection structure.

[0014] By adopting the above technical solution, this utility model has the following advantages:

[0015] To prevent problems caused by large amounts of impurities, rainwater harvesting devices for green buildings can be equipped with a harvesting mechanism under the roof. This mechanism has a collection section facing the roof, and a second filter with larger mesh is installed to prevent injury to users. This second filter primarily serves as support for the collection section, preventing injury to users. Impurities such as leaves and soil are generally not blocked at this location. The harvesting mechanism actively harvests rainwater through a collection structure, preventing blockages caused by passive harvesting. The collection structure rotates within the housing, and multiple scrapers extend from the rotating shaft towards the inner wall of the housing. The segmented cavities formed between adjacent scrapers can store rainwater in stages. When one segmented cavity carries rainwater to the pressure regulating structure for pressurization and downward movement, another segmented cavity can connect to the collection section for rainwater harvesting.

[0016] The regulating structure is generally a fan. By pressurizing one side of the collection structure, the collection structure can be driven to rotate. Since each segment chamber is sealed before being connected to the filter section, after pressurization at the segment section, when the segment section moves to the filter section, the pressurized pressure can act on the rainwater in the segment section, allowing it to pass through the first filter screen more quickly and enter the water tank. This structure enables rapid active rainwater recovery. As the collection structure continues to rotate, the scraper can scrape the first filter screen, removing impurities and preventing clogging. This structure ensures the efficiency and stability of rainwater recovery.

[0017] The water tank has a drainage structure on the side away from the shell. The filtered water is collected through the water tank and can be connected to the household pipe, making it more convenient for users to use the water in the tank and improving the user experience more efficiently and conveniently.

[0024] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0026] The following is in conjunction with the reference appendix. Figures 1 to 3 The present invention will be further described below.

[0027] The present invention proposes a green building roof rainwater recycling device, which includes a water tank 1, a recycling mechanism 3 located at one end of the water tank 1 and a drainage mechanism 2 located at the other end of the water tank 1. The recycling mechanism 3 is provided with a housing 31 connected to the water tank 1. The housing 31 facing the water tank 1 is provided with a filter part 32 on which a first filter screen is installed. The end of the housing 31 away from the filter part 32 is provided with a liquid collection part 33 on which a second filter screen is installed.

[0028] The housing 31 is rotatably connected to a collection structure 4 consisting of multiple scrapers 41 connected to the inner wall of the housing 31. Adjacent scrapers 41 and the inner wall of the housing 31 are sandwiched to form a segmented cavity. A pressure regulating structure 35 is provided on one side of the housing 31 along the rotation direction of the collection structure 4 toward the segmented cavity.

[0029] To prevent problems caused by a large amount of impurities, a rainwater harvesting device for green building roofs can be installed under the roof to prevent rainwater harvesting from malfunctioning. The harvesting device 3 has a collection section 33 facing the roof. To prevent injury to users at this location, a second filter is installed at the collection section 33. The second filter has a larger mesh size and is mainly used as a support for the collection section 33 to prevent injury to users. Impurities such as leaves and soil are generally not blocked at this location. The harvesting device 3 uses a collection structure 4 to actively harvest rainwater and prevent blockages caused by passive harvesting. The collection structure 4 rotates inside the housing 31. The collection structure 4 has multiple scrapers 41 extending from the rotating shaft toward the inner wall of the housing 31. The segmented cavities formed between adjacent scrapers 41 can store rainwater in stages. When one segmented cavity carries rainwater to the pressure regulating structure 35 and moves downward under pressure, another segmented cavity can be connected to the collection section 33 for rainwater harvesting.

[0030] The regulating structure is generally a fan. By pressurizing one side of the collection structure 4, the collection structure 4 can be driven to rotate. Since each segment cavity is sealed before being connected to the filter section 32, after pressurization at the segment, when the segment moves to the filter section 32, the pressurized pressure can act on the rainwater in the segment, allowing it to pass through the first filter screen more quickly and enter the water tank 1. This structure enables rapid active rainwater recovery. As the collection structure 4 continues to rotate, the scraper 41 can scrape the first filter screen, removing impurities and preventing clogging. This structure ensures the efficiency and stability of rainwater recovery.

[0031] The water tank 1 has a drainage structure on the side away from the shell 31. The filtered water is collected through the water tank 1. The drainage structure can be connected to the household pipe, so that users can make more convenient use of the water in the water tank 1, and improve the user experience more efficiently and conveniently.

[0032] In one embodiment of this application, the scraper 41 is provided with a reinforcing part 42 connected to the inner wall of the housing 31 along the side opposite to the rotation direction of the collection structure 4. The reinforcing part 42 is connected to the scraper 41 and the inner wall of the housing 31, which improves the structural strength of the end of the scraper 41 near the first and second filter screens. This can make it easier for the scraper 41 to scrape impurities in the water from the filter screen, avoid clogging of the filter section 32, and strengthen the structure of the scraper 41 to prevent the scraper 41 itself from being damaged during rotation.

[0033] In one embodiment of this application, the housing 31 is provided with an opening relative to the pressure regulating structure 35, and the pressure regulating structure 35 is provided with a guide portion 36 provided along the extension direction of the reinforcing portion 42 relative to the opening portion, and a pressure regulating component is connected to one end of the guide portion 36 away from the opening portion.

[0034] The length of the outer periphery of the reinforcing part 42 is less than the length of the outer periphery of the open part.

[0035] The pressure regulating structure 35 is generally a fan. The fan is connected to the open end of the housing 31 through the obliquely set guide part 36. By being obliquely set along the rotation direction of the collecting structure 4, the fan can drive the scraper 41 to rotate, ensuring the stability of the operation of the collecting structure 4. The arc circumference of the reinforcing part 42 is smaller than the arc circumference of the open end, which allows the fan to constantly drive the scraper 41 and ensure the stability of the scraper 41 operation.

[0036] In one embodiment of this application, the rotating shaft of the collecting structure 4 passes through the housing 31 and is connected to a reduction gear set 5. One end of the reduction gear set 5 is provided with a reduction end connected to the collecting structure 4, and the other end is provided with a power generation end connected to a generator.

[0037] To ensure sufficient pressure is accumulated in each compartment and to guarantee the filtration efficiency of rainwater at the filter section 32, a reduction gear set 5 is provided at the rotating shaft of the collection structure 4. The reduction gear set 5 consists of one or more planetary gear sets. One end of the planetary gear set is a gear ring serving as the reduction end, and the other end is a power generation end serving as the sun gear. Because the radius of the gear ring is larger than the radius of the sun gear, there is a difference in angular velocity between the two when the linear speed is the same, thus achieving a reduction effect. The collection structure 4 connected to the reduction section allows each compartment to accumulate higher air pressure, while the rapid rotation at the power generation end can be used to recover excess energy, making the entire active rainwater recycling device more energy-efficient and environmentally friendly, and effectively improving the user experience.

[0038] In one embodiment of this application, a third filter screen 11 is provided in the water tank 1 relative to the filter section 32. An activated carbon layer is provided on the side of the third filter screen 11 opposite to the housing 31 and relative to the drainage mechanism 2. The drainage mechanism 2 is connected to the activated carbon layer. The third filter screen 11 is used for further filtration, and then the activated carbon is used for adsorption, which can effectively allow rainwater to be used directly and ensure the user's experience.

[0039] In one embodiment of this application, the drainage mechanism 2 includes a three-way pipe 21 connected to the water tank 1 and a drain pipe 22 located at the end of the three-way pipe 21 away from the water tank 1. The three-way pipe 21 has an installation part for installing the household water pipe between the water tank 1 and the drain pipe 22.

[0040] The T-pipe 21 allows water in the water tank 1 to be directed from the installation section to the location where water is needed, making it easier to recycle rainwater. The drain pipe 22 can drain excess water when the water tank 1 is full, effectively preventing damage caused by insufficient load-bearing capacity of the water tank 1.

[0041] In one embodiment of this application, a slag collection section 34 is provided at the end of the housing 31 away from the pressure regulating structure 35, and the pressure regulating structure 35, the filter section 32 and the slag collection section 34 are arranged sequentially along the rotation direction of the collection structure 4.

[0042] The housing 31 is also provided with a slag collection section 34. After the rainwater is filtered at the filter section 32, the remaining rainwater and impurities can be discharged at the slag collection section 34 under the action of the scraper 41, so that the inside of the housing 31 can be kept clean.
