Description

Technical Field

[0001] This invention belongs to the field of rainwater harvesting and environmental protection technology, specifically relating to an integrated rainwater power generation device and its recycling system suitable for multi-story buildings. Background Technology

[0002] Rainfall, a natural precipitation phenomenon, is generated by atmospheric circulation disturbances and is an important component of the atmospheric water cycle. However, only 2.5% of the Earth's freshwater resources are directly usable by humans, and the vast majority of these are frozen at the North and South Poles. Therefore, the use of water resources is extremely important.

[0003] During rainfall, most of the rainwater is lost directly into rivers, and very little of it can be used directly, resulting in a waste of rainwater resources.

[0004] Chinese Patent Publication No. CN109235539A discloses a rainwater collection and reuse device for building floors, including a box. A quartz sand filter, a HEPA filter, and an activated carbon filter layer are sequentially fixedly connected from top to bottom to the upper part of the box's inner cavity. An ultraviolet lamp is fixedly connected to the lower right side of the inner cavity. This invention, by sequentially connecting the quartz sand filter, HEPA filter, and activated carbon filter layer from top to bottom to the upper part of the box's inner cavity, can perform triple filtration on rainwater flowing into the box from a pipe connected to a pre-set drainage pipe on the floor. This solves the problem of wasted rainwater due to the lack of collection devices for rainwater flowing down building floors. However, this filtered rainwater still contains a significant number of microorganisms, which could be unhealthy to drink directly, and this filtration device greatly increases the cost of filtration.

[0036] ​The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort belong to the scope of the present application.

[0037] As shown in Figure 1 , Figure 2 , the embodiment of the present application provides a rainwater integrated power generation device suitable for floors, which comprises a rainwater collecting mechanism 1, a water storage mechanism 2, a power generation mechanism 3 and a water storage mechanism 4.

[0038] The rainwater collecting mechanism 1 is located at the top of the floor, and the rainwater collecting mechanism 1 is in a funnel-shaped structure and is located at the position of the drainage outlet at the top of the floor. This position is generally arranged at the edge position (i.e. the lower position) of the floor. A grating net can be arranged for collecting rainwater, which can effectively realize preliminary filtration of rainwater and avoid blockage of the pipeline by larger leaves and other objects.

[0039] As shown in Figure 3 , the water storage mechanism 2 is arranged on each floor (the specific position can be arranged at the joint position of the wall surface, which can effectively save the effective use area of the floor), which comprises a straight pipeline 21 and a water storage barrel 22. The water storage barrel 22 is arranged on each floor, and the water in the water storage barrel 22 can be stored as secondary water for toilets. The straight pipeline 21 is used to connect the water storage barrels 22 between the upper and lower floors, and the water flow flows between the straight pipeline 21 and the water storage barrel 22. When the water storage barrel 22 of the upper floor is full to the specified water amount, the water will overflow through the straight pipeline 21 into the water storage barrel 22 of the next floor, and finally flow into the water storage mechanism 4 after the water amount of the water storage barrel 22 of each floor is full.

[0040] A water outlet 201 is arranged at the side of the water storage barrel 22, which can directly communicate with each toilet or other secondary water position of each floor to facilitate direct water taking. A sand discharge port 202 is arranged at the bottom position of the water storage barrel 22, and the water storage barrel 22 is in a funnel-shaped structure with a wide upper part and a narrow lower part, and the sand discharge port 202 is arranged at the narrow lower part. A control valve 23 is arranged at the position of the sand discharge port 202; the control valve 23 is arranged in a double-layer structure and is independently controlled by an electromagnetic valve. In specific use, the control valve 23 at the upper layer is first opened, at which time the sand deposited at the bottom of the water storage barrel 22 will leak into the cavity between the control valves 23 of the upper and lower layers, and then the control valve 23 at the upper layer is closed and the control valve 23 at the lower layer is opened, so that the sand and gravel previously deposited in the cavity between the control valves 23 of the upper and lower layers is recovered and can be periodically recovered.

[0041] AsFigure 4 As shown, the power generation mechanism 3 is located on the straight-through pipeline 21 between the upper and lower groups of water storage buckets 22, so that each group of power generation mechanisms 3 is independently connected to the storage battery for energy storage; at least two groups of power generation mechanisms 3 are arranged on the straight-through pipeline 21 between the water storage buckets 22 according to the actual height of the floor, which can be adjusted to fully use the potential energy difference water flow.

[0042] The straight-through pipeline 21 is arranged at the upper end of the water storage bucket 22, so that when the water storage in the water storage bucket 22 reaches a certain height, it directly overflows from the side of the straight-through pipeline 21 into the water storage bucket 22 of the next floor without manual operation, and the water outlet 201 is located at a lower level than the water outlet level of the straight-through pipeline 21. This height can fully utilize the water level in the water storage bucket 22 and avoid turbidity caused by pumping, which affects use.

[0043] As shown, Figure 5 The water storage mechanism 4 is located outside the floor and is used to receive the water flow falling from each water storage mechanism 2. The water storage mechanism 4 is arranged in multiple groups, and a potential difference height is arranged between the multiple groups. The power generation mechanism 3 is arranged between the potential difference height. This water flow has low cleanliness and can be used for cleaning large equipment in a factory or a community or for irrigation. Even when it is discharged into a sewer, it can also use the electric energy accumulated by the power generation mechanism 3 according to the potential difference, fully utilizing water resource storage and multiple uses. The power generation mechanism 3 uses a impeller type generator, which can realize normal power generation without causing pipeline blockage due to many impurities in the straight-through pipeline 21.

[0044] According to the need, a flow meter is arranged on each group of power generation mechanisms 3 to monitor the flow of water in the pipeline in real time. When blockage occurs, the flow will be blocked, so that timely maintenance can be performed to avoid serious blockage. A power digital flow meter can also be arranged on each group of power generation mechanisms 3 according to the need to facilitate the control of stored power. The electric energy of the storage battery can be used as a source of household electricity, such as a small power electrical sensor. A water quality monitor is arranged in the water storage bucket 22 or the water storage mechanism 4 to monitor the water quality so that it can be treated in time when the water quality is polluted.

[0045] Each group of water storage mechanisms 2 is independently controlled in the vertical position, so it can be independently arranged on the outer facade or inner wall of the wall according to the need. It can be applied to the use of a community or a single floor between floors, and can also be applied to the use of a factory according to the need. It can be adapted to local conditions to greatly meet the actual needs of use.

[0046] The factory area or residential area can be independently used as a system to share a set of water storage mechanisms 4, the flow mode of the residential area to the street block is used as a system to share a set of water storage mechanisms 4, and the mode of finally flowing into the sewer pipe is used as the last system. Each set of systems can be independently provided with a power generation mechanism 3 for power generation due to the potential difference. When the residential area between floors is shared, the water storage mechanism 4 can also be shared, that is, it can be used for irrigation and can also be used for cleaning or water storage.

[0047] The recycling system of the rainwater integrated power generation device suitable for floors includes the following steps:

[0048] S1, first, the rainwater collection mechanism 1 collects and returns the rainwater to the water storage mechanism 2.

[0049] S2, the water flow flows into the water storage barrels 22 of each floor in turn through the straight-through pipelines 21 from the water storage barrel 22 of the upper floor. When the water flow flows in the straight-through pipelines 21, the power generation mechanism 3 generates power, and the power generation is stored in the battery.

[0050] S3, until the water storage barrel 22 of each floor is full, the water flow continues to flow into the water storage mechanism 4 outside the floor, and the power generation mechanism 3 located on the water storage mechanism 4 performs secondary independent power generation, and the power energy of the power generation is stored for standby use.

[0051] The above shows and describes the basic principles, main features and advantages of the present application. It should be understood by those skilled in the art that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application.
