[0002] With the acceleration of urbanization, the number of buildings has continued to increase, and the amount of rainwater runoff from roofs has increased significantly. The current scattered drainage methods and phenomena of downpipes can be seen everywhere.

[0003] The direct discharge of large amounts of untreated rainwater not only leads to the accumulation of urban surface runoff, increasing the burden on the drainage system and becoming a risk factor for urban flooding; the scattered drainage of rainwater from rooftops also leads to an increase in urban non-point sources and waste of rainwater resources, among other problems.

[0004] In the existing technology, the natural discharge of rainwater collected on roofs through various devices such as downpipes and rain barrels that have been built or are under construction cannot meet the requirements of effective retention and precise management. In addition, the rain barrels in the existing technology need to be emptied manually after storing water, which not only increases the cost of facility maintenance and management, but also may not be emptied in time, resulting in the facility being unable to effectively retain water for each rainfall.

[0031] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0032] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0033] Reference Figure 1 As shown, some embodiments of the present invention provide a rainwater storage device, including: a storage tank 1, a sensor 2 and a controller 3; the storage tank 1 is provided with a connecting pipe 4; the sensor 2 is arranged below the drain outlet of the rainwater downpipe 5, and the sensor 2 is suitable for detecting rainfall signals; the controller 3, the connecting pipe 4 and the sensor 2 are all communicated with the controller 3, and the controller 3 is suitable for receiving rainfall signals to control the extension and retraction of the connecting pipe 4, and the first end of the connecting pipe 4 has a water storage state extending to the drain outlet of the rainwater downpipe 5, and has a water stop state retracted into the storage tank 1.

[0034] Specifically, sensor 2 is located below the drain outlet of rainwater downpipe 5 and is used to detect rainfall signals. Sensor 2 is in communication with controller 3, which receives the rainfall signals and controls the expansion and contraction of connecting pipe 4 based on the rainfall signals, so that the first end of connecting pipe 4 can be extended to the drain outlet of rainwater downpipe 5 to store water, and can be retracted to the storage tank 1 to stop storing water. This rainwater storage device realizes automated rainwater storage and regulation, reduces labor costs, thus avoiding urban waterlogging, and effectively collects rainwater, avoiding the waste of rainwater resources.

[0035] It is understood that the sensor 2 is a rainfall sensor 2, which is installed on the ground and is arranged corresponding to the drainage outlet of the rainwater downpipe 5. The sensor 2 has a flow sensor and a water pressure sensor. The flow sensor of the sensor 2 is used to detect the flow parameter of the rainwater flowing through the rainwater downpipe 5 and falling on the sensor 2, and the water pressure sensor is used to detect the pressure parameter of the rainwater falling on the sensor 2. When the rainwater flow parameter and / or the rainwater pressure parameter are greater than or equal to the preset rainwater flow threshold and rainwater pressure threshold, the sensor 2 sends a rainfall signal to the controller 3. When the rainwater flow parameter and / or the rainwater pressure parameter are less than the preset rainwater flow threshold and rainwater pressure threshold, the sensor 2 stops sending the rainfall signal.

[0036] When the controller 3 receives a rainfall signal, it controls the connecting pipe 4 to extend so that the first end of the connecting section extends to just below the drain outlet of the downpipe 5, so as to receive rainwater and store rainwater. When the sensor 2 stops sending a rainfall signal, the rainfall signal disappears, or the controller 3 cannot receive a rainfall signal, the controller 3 controls the connecting pipe 4 to contract to stop storing rainwater.

[0037] It should be noted that the connecting pipe 4 is made of UPVC (Unplasticized Polyvinyl Chloride) or stainless steel and is a tubular structure with a diameter of 100-110 mm. When the controller 3 issues an extension command in response to a rainfall signal, the first end of the connecting pipe 4 extends toward the downpipe 5. The port at the first end of the connecting pipe 4 is coaxial with the drain outlet of the downpipe 5, and the distance between the port at the first end of the connecting section and the drain outlet of the downpipe 5 is 100-150 mm.

[0038] In some embodiments of the present invention, the regulating reservoir 1 includes a main body 11 and a cover plate 12, the main body 11 is provided with a water storage chamber 13, the cover plate 12 is covered on the main body 11, the connecting pipe 4 is provided in the cover plate 12, and the second end of the connecting pipe 4 is connected to the water storage chamber 13.

[0039] Specifically, the body 11 is made of stainless steel and can be configured as a block or cylindrical structure depending on the application scenario. The water storage chamber 13 is a square or cylindrical cavity. The second end of the connecting pipe 4 is connected to the water storage chamber 13 to drain rainwater into the water storage chamber 13.

[0040] It can be understood that the cover plate 12 is placed on the main body 11 and the connecting pipe 4 is placed inside the cover plate 12 to achieve a buried arrangement.

[0041] In some embodiments of the present invention, the diameter of the connecting pipe 4 is larger than that of the rain down pipe 5 . In the water storage state, the port at the first end of the connecting pipe 4 is located directly below the drain outlet of the rain down pipe 5 .

[0042] Specifically, because the connecting pipe 4 and the rainwater downpipe 5 are connected in a non-contact manner, the diameter of the connecting pipe 4 is larger than that of the rainwater downpipe 5 to ensure rainwater storage. This non-contact connection avoids changes to the existing structure and drainage method of the rainwater downpipe 5 and helps to ensure the drainage safety of the rainwater downpipe 5 during heavy rain, torrential rain, and heavy downpours. Furthermore, it improves versatility.

[0043] In some embodiments of the present invention, a water collecting trough is provided at the first end of the connecting pipe 4 . The water collecting trough is a funnel-shaped structure, and the water collecting trough is directly below the rainwater downpipe 5 .

[0044] Specifically, a funnel-shaped water collection trough is provided at the first end of the connecting pipe 4 to improve water collection efficiency during water storage. Specifically, the trough is made of UPVC (Unplasticized Polyvinyl Chloride) or stainless steel, with an inner diameter of 130-160mm at the upper edge, which is larger than the outer diameter of the drain outlet of the downpipe 5. During water storage, the trough is positioned 100-150mm directly below the drain outlet of the downpipe 5. The trough is connected to the connecting pipe 4 via a socket-and-spigot connection, secured with a flange.

[0045] In some embodiments of the present invention, a drain port 112 is provided at the bottom of the body 11 , and a drain valve 111 is provided at the drain port 112 . The drain valve 111 is communicatively connected to the controller 3 .

[0046] Specifically, an emptying port 112 is provided at the bottom of the main body 11, the emptying hole is connected to the water storage chamber 13, and an emptying valve 111 is provided at the emptying port 112. The controller 3 is communicated with the emptying valve 111, and the controller 3 controls the opening and closing of the emptying valve 111 to realize the drainage of the water storage chamber 13. It can be understood that the emptying port 112 is connected to the external pipeline to discharge the discharged rainwater into the rainwater pipe network, green space, rainwater garden and other drainage settings in the application scenario.

[0047] In some embodiments of the present invention, a water level sensor 114 is provided in the body 11 , and the water level sensor 114 is suitable for monitoring the water level parameters in the water storage chamber 13 in real time.

[0048] Specifically, a water level sensor 114 is set in the water storage chamber 13. When the water storage amount in the water storage chamber 13 reaches the maximum water storage amount, the water level sensor 114 feeds back the water level height parameter to the controller 3. The controller 3 controls the drain valve 111 to open to achieve drainage and avoid accidents caused by excessive water storage.

[0049] It will be appreciated that in some embodiments of the present invention, the maximum single water storage capacity of the water storage chamber 13 is 625L, and the maximum water storage height is 100cm. The water level sensor 114 has a measurement accuracy of 1cm. In some embodiments of the present invention, an alarm device is also provided. When the water level sensor 114 detects that the water level parameter reaches a preset height, the controller 3 controls the alarm device to activate. This allows manual drainage to ensure safety in the event of a malfunction of the drain valve 111.

[0050] In some embodiments of the present invention, an overflow port is provided on the top of the body 11 .

[0051] Specifically, an overflow port is set at the top of the main body 11, and the height of the overflow port is equal to the maximum water level height of the water storage chamber 13. When the drain valve 111 fails, the setting of the overflow port can ensure that the water storage component will not exceed the maximum water storage capacity, thereby ensuring safety and avoiding accidents.

[0052] In some embodiments of the present invention, a water quality sensor is provided within the water storage chamber 13, and the water quality sensor is in communication with the controller 3. The water quality sensor is adapted to detect the water quality parameters of the rainwater stored within the water storage chamber 13 and provide real-time feedback to the controller 3. It is understood that when the rainwater stored in the regulating reservoir 1 needs to be processed and reused, it is necessary to detect the rainwater quality parameters to ensure that the rainwater meets the usage standards. In some embodiments of the present invention, the water quality sensor can be configured to monitor one or more indicators such as SS (Suspended Solids), CODCr (Dichromate Index), TP (Total Phosphorus), and TN (Total Nitrogen).

[0053] The utility model proposes a rainwater storage control method, comprising the following steps:

[0054] Sensor 2 monitors rainfall signals and feeds back to controller 3 in real time;

[0055] The controller 3 receives a rainfall signal and controls the first end of the connecting pipe 4 to extend to just below the drain outlet of the rainwater downpipe 5;

[0056] When the rainfall signal disappears, the controller 3 controls the first end of the connecting pipe 4 to retract into the water reservoir.

[0057] Specifically, sensor 2 monitors rainfall signals and provides real-time feedback to controller 3. Upon receiving the rainfall signal, controller 3 controls the first end of connecting pipe 4 to extend directly below the drain outlet of downpipe 5. When the rainfall signal disappears, controller 3 controls the first end of connecting pipe 4 to retract into the reservoir. This rainwater storage and regulation control method is simple and convenient, enabling automated rainwater storage and regulation, thereby reducing labor costs.

[0058] It is understandable that when the rainfall signal disappears for longer than a preset time threshold, the controller 3 controls the drain valve 111 to open to drain the rainwater stored in the storage tank 1 to ensure that there is enough storage space for the rainwater during the next rainfall.

[0059] A rainwater storage control method comprises the following steps:

[0060] The sensor 2 detects rainfall signals from previous years, and the controller 3 statistically analyzes the rainfall amount and rainfall process changes in the same period of previous years in the area based on the rainfall signals. According to the rainfall amount and rainfall process changes, the preset time periods are: the beginning of rainfall, the middle of rainfall, and the end of rainfall.

[0061] At the beginning of rainfall, the controller 3 controls the connecting pipe 4 to be in a stopped storage state, and the controller 3 controls the drain valve 111 to be closed;

[0062] In the middle of the rainfall process, the controller 3 controls the connecting pipe 4 to be in a water storage state when the rainfall is increasing over time according to the rainfall amount and the rainfall process; and controls the connecting pipe 4 to be in a water stop state when the rainfall is decreasing over time.

[0063] After the rainfall ends, the controller 3 controls the drain valve 111 to open.

[0064] Specifically, the sensor 2 detects rainfall signals over the years, and the controller 3 counts and analyzes the rainfall and rainfall process changes in the same area and the same period in previous years based on the rainfall signals over the years. According to the rainfall and rainfall process changes, the rainfall time periods are preset, which are the early rainfall period, the middle rainfall period and the late rainfall period. The controller 3 collects rainwater by controlling the expansion and contraction of the connecting pipe 4 in the three time periods respectively. The rainwater storage method can be used in situations where the current rainfall cannot be predicted to ensure the storage of rainwater in the storage pool 1, thereby avoiding the occurrence of urban waterlogging, improving the rainwater collection capacity, and avoiding the waste of rainwater resources.

[0065] It is understandable that the rainwater storage control method can realize storage according to the change of rainfall, increase autonomy, and ensure that rainwater can be collected when rainfall suddenly increases, so as to avoid the occurrence of urban waterlogging.

[0066] In some embodiments of the present invention, the water level sensor 114 detects the water level parameter in the water storage chamber 13 in real time. When the water level parameter is greater than or equal to a preset water level threshold, the controller 3 controls the drain valve 111 to open.

[0067] Specifically, to ensure the stability and safety of the structure, in the water storage state, when the water level sensor 114 detects that the water level parameter is greater than or equal to the preset water level threshold, the controller 3 controls the drain valve 111 to open.

[0068] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
