Technical Field

[0001] The utility model belongs to the technical field of automatic diversion of rainwater drainage, and particularly relates to an intelligent diversion control device for rainwater collection in a vehicle depot. Background Art

[0002] The rainwater storage tank is one of the important measures in the construction of sponge cities. Rainwater is collected through the pipe network and enters the rainwater storage tank through a rainwater diversion well. The collected rainwater can be used for various purposes such as greening irrigation, road watering, landscape water replenishment, and car washing after purification, so as to achieve the purpose of saving water resources and alleviating the water use pressure.

[0003] The key element of rainwater collection and utilization is to ensure the quality of the recycled rainwater. To ensure the quality of the recycled rainwater, there are generally two methods: "collecting clean rainwater + simple purification treatment" and "collecting rainwater uniformly + enhanced purification treatment". In actual life, the first method is mainly used, which can reduce the cost of rainwater recycling.

In addition, floating pollutants such as oil stains in the rainwater of the vehicle depot are removed, and the operation data is recorded to form an operation scenario database, which provides support for the intelligent management of rainwater collection in the vehicle depot.

[0035] As shown Figure 1 in the figure, the flow splitting well 1 adopts an integral structure, and an inspection well and a ladder 7 are arranged in the flow splitting well 1.

[0036] Specifically, in this embodiment, the flow splitting well 1 adopts an integral stainless steel structure or a cast-in-place reinforced concrete structure on site. Alternatively, the flow splitting well 1 can also adopt an integral structure of other materials.

[0037] As shown Figure 1 in the figure, a scum baffle 16 is arranged at the inlet of the collecting pipe 4.

[0038] Specifically, when the sewage in the water inlet pipe 2 enters the flow splitting well 1, the sewage first passes through the scum baffle 16 arranged at the inlet of the collecting pipe 4. The scum baffle 16 intercepts floating pollutants such as oil stains outside the collecting pipe 4, and the downward-opening hydraulic gate 6 intercepts the sewage on one side of the flow splitting well 1.

The multi-functional water quality sensor 8, the flow sensor 9 and the water level sensor 10 are electrically connected to the monitoring host 13.

[0040] Specifically, the flow, water quality, liquid level, etc. of the rainwater are monitored through the water quality sensor 8, the flow sensor 9 and the water level sensor 10, and the relevant data are transmitted to the monitoring host 13 through the signal line.

[0041] As shown Figure 1 in the figure, the signal lines of the multi-functional water quality sensor 8, the flow sensor 9 and the water level sensor 10 are fixed together by a fixing rod 12.

[0042] Specifically, the signal lines of the multi-functional water quality sensor 8, the flow sensor 9, and the water level sensor 10 are fixed together by the fixing rod 12, which can prevent the signal lines from getting chaotic, save space, and look neater and tidier.

[0043] As Figure 1 shown, the installation position of the multi-functional water quality sensor 8 is 10 cm higher than the bottom of the water inlet pipe 2.

[0044] Specifically, installing the multi-functional water quality sensor 8 at a position 10 cm higher than the bottom of the water inlet pipe 2 can better sense and detect the water quality in the entire water inlet pipe 2.

[0045] As Figure 1 shown, the monitoring host 13 is electrically connected to the hydraulic gate 5, the bottom-opening hydraulic gate 6, and the control and storage device 15.

[0046] Specifically, the multi-functional water quality sensor 8, the flow sensor 9, and the water level sensor 10 are used to monitor the flow rate, water quality, liquid level, etc. of rainwater, and transmit the relevant data to the monitoring host 13 through the signal line. The monitoring host 13 then transmits the signal to the control and storage device 15 for analysis and storage. At the same time, the hydraulic gate 5 and the bottom-opening hydraulic gate 6 are controlled to open and close by the control and storage device 15. The opening and closing state instructions are comprehensively determined by the values of the monitoring equipment, and the operation opening and closing states are stored in the control and storage device 15.

[0048] Specifically, the control and storage device 15 is provided with a control device, which has an Internet connection function, a weather forecast data module, and can view relevant data and control relevant devices through the PC side and the mobile phone side.

[0049] As Figure 1 shown, the monitoring host 13 is electrically connected to a self-recording rain gauge 17.

[0050] Specifically, the self-recording rain gauge 17 can record the data recorded by the multi-functional water quality sensor 8, the flow sensor 9, and the water level sensor 10 through the monitoring host 13.

[0051] As Figure 1 shown, the top of the bottom-opening hydraulic gate 6 is 10 cm higher than the top elevation of the water inlet pipe 2.

[0052] Specifically, the top of the bottom-opening hydraulic gate 6 is 10 cm higher than the top elevation of the water inlet pipe 2, which is used to intercept the sewage flowing into the diversion well 1 in the water inlet pipe 2 and prevent the unfiltered and purified sewage from flowing into the outlet pipe 3.

[0063] 4) The relationship between the data recorded by the multi-functional water quality sensor 8 and the opening and closing data of the hydraulic gate 5 and the downward-opening hydraulic gate 6;

[0064] 5) Record the relationship between the weather forecast data and the data recorded by the multi-functional water quality sensor 8, the flow sensor 9, and the water level sensor 10, and deduce the relationship between the weather forecast data and the amount of high-quality rainwater that can be collected with SS ≤ 20 mg / L and COD ≤ 70 mg / L or the amount of sub-high-quality rainwater with 20 ≤ SS ≤ 40 mg / L and 70 ≤ COD ≤ 100 mg / L.

[0065] 6) Record the relationship between the weather forecast data and the data recorded by the storage tank pump, the storage tank liquid level, and the storage tank volume.

[0067] 1) Combine the above-mentioned relationship between the weather forecast data and the amount of high-quality rainwater that can be collected with SS ≤ 20 mg / L and COD ≤ 70 mg / L, and empty the corresponding storage tank space in advance.

[0068] 2) In the water-scarce season, combine the above-mentioned relationship between the weather forecast data and the amount of sub-high-quality rainwater with 20 ≤ SS ≤ 40 mg / L and 70 ≤ COD ≤ 100 mg / L, and supplement the water volume in the storage tank in a timely manner.
