Technical Field

[0001] The utility model belongs to the technical field of water supply and drainage, and relates to a solar energy rainwater and sewage diversion device for a rainwater ditch. Background Art

[0002] A stormwater ditch is a waterway system used to collect and drain rainwater. Its main function is to discharge rainwater from roofs, roads and other surfaces into sewers, rivers or lakes to alleviate urban waterlogging and reduce flood risks. In urban planning, stormwater ditches play an important role in drainage and governance. Stormwater ditches are currently mainly used in compact residential areas, street shops and other scenarios, and are widely used in rural counties and other areas. Stormwater ditches are set up in the open air and are difficult to manage. In daily life, domestic sewage, car wash water, etc. are often dumped directly into rainwater ditches, causing sewage to enter the river, which is difficult to completely divert. At present, there are no effective diversion measures for dumping into rainwater ditches. Summary of the invention

It should be understood that the data used in this way can be interchanged where appropriate, so as to describe the embodiments of the utility model described herein. In addition, similar terms such as "including" and "having" mean that in addition to those contents already listed in "including" and "having", other contents that have not been listed can also be "included" and "having"; for example, a process, method, system, product or device that can include a series of steps or units is not necessarily limited to those steps or units that have been clearly listed, but can include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0022] Due to the angle of the drawing, some components may not be drawn, but their positions and connection relationships can be partially understood based on the text expression.

[0023] like Figure 1 As shown, the utility model is a solar rainwater and sewage diversion device suitable for a rainwater ditch 10, comprising a rainwater diversion well chamber 8 and a sewage transition well chamber 7, the rainwater diversion well chamber 8 is provided with a connected water inlet, a rainwater outlet, and a sewage transition outlet, a rainwater gate 2 is installed at the rainwater outlet, and a connected sewage transition inlet and a sewage final outlet are provided on the sewage transition well chamber 7, and the sewage transition outlet and the sewage transition inlet are connected and cut off through the sewage gate 1. The sewage valve 1 and the rainwater gate 2 are controlled to open and close by a rainfall sensor.

[0024] In order to intercept garbage such as leaves and debris, a sewage well chamber grille plate 3 is installed before the final sewage outlet, and a rainwater well chamber grille plate 4 is installed before the rainwater outlet. Manual garbage removal is carried out regularly.

[0025] In order to facilitate the connection between the sewage transition well chamber 7 and the sewage pipe, a sewage connection flange 5 is installed outside the final sewage outlet.

[0026] The sewage valve 1 and the rain gate 2 are electric gates. The sewage valve 1, the rain gate 2 and the rain sensor are powered by the solar photovoltaic panel 6. The solar photovoltaic panel 6 is connected to the sewage valve 1 and the rain gate 2 through the energy storage battery 9. The solar photovoltaic panel 6 and the energy storage battery 9 are installed on the bracket. The solar photovoltaic panel 6 is located above the energy storage battery 9. The rain sensor is installed on the solar photovoltaic panel 6.

[0027] On sunny days, the solar photovoltaic panel 6 stores energy, which is converted into electrical energy and stored in the energy storage battery 9. The sewage valve 1 is always open on sunny days, and the rainwater gate 2 is always closed on sunny days.

[0028] The sewage valve 1, the rainwater gate 2 and the rainfall sensor are all connected to the controller.

[0029] The sewage transition well chamber 7 and the rainwater diversion well chamber 8 are made of stainless steel.

[0030] The rainwater diversion well chamber 8 is installed in the rainwater ditch 10 , and the sewage transition well chamber 7 is connected to the sewage pipe through the sewage connection flange 5 .

[0031] Figure 2 It is in the running state on a sunny day, and the rain sensor state is that it is not raining. At this time, the sewage gate 1 is open, the rainwater gate 2 is closed, and the solar photovoltaic panel 6 is in the energy storage state, converting solar energy into electrical energy and storing it in the solar cell.

[0032] The gate is controlled according to the detection of the rain sensor. In sunny mode, the alarm gate is in the closed state.

[0033] After the sewage enters the rainwater ditch 10, it enters the rainwater diversion well chamber 8 from the water inlet. Since the rainwater gate 2 is closed, the sewage passes through the sewage transition outlet and the sewage transition inlet into the sewage transition well chamber 7 and then enters the sewage pipe from the sewage final outlet.

[0034] Figure 3 It is the operating state on rainy days. When the rain sensor detects rain, the system starts to calculate the accumulated rainfall according to the rain sensor. When the accumulated rainfall value reaches the gate opening threshold in the system (the accumulated value is 2mm), the system opens the rainwater gate 2 and closes the sewage gate 1. After the rainwater gate 2 is opened, when the sensor detects that it is not raining and the 5-minute rainfall value is less than the gate closing threshold set by the system (0.2mm), the system considers that the rainfall has stopped or decreased to almost no rain. At this moment, less rainwater flows into the rainwater pipe. In order to prevent sewage from flowing into the river channel and closing the rainwater gate 2, it is recommended to close the rainwater gate 2 after a delay of 10 minutes and open the sewage gate 1. The specific delay time can be adjusted according to the actual situation on site.

[0035] Figure 4 As shown, the solar photovoltaic panel 6 and the rain sensor are respectively connected to the controller, which is a PLC. The PLC controller converts analog signals and controls the equipment, and the PLC controller is respectively connected to the sewage valve 1 and the rainwater gate 2.

[0036] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
