[0027] Embodiment 1

[0028] Due to the following characteristics of rainwater: the initial rainwater carries ground scouring pollutants such as chemical oxygen demand (COD), suspended solids, heavy metals, etc., and has a high pollution risk, and needs to be collected separately to prevent water pollution accidents. The cleanliness of the later rainwater is relatively high, and can be infiltrated and recycled through urban sponge facilities, thereby realizing the full utilization of rainwater resources. The rainwater classification and collection method in the prior art relies on traditional manual operation or single liquid level control, and cannot respond to water quality changes and the saturation state of the sponge facility in real time, so the rain and sewage diversion effect is poor. In this regard, please refer to Figure 1 and Figure 2 The present application provides an intelligent switching device 100, Figure 1 a top view structural diagram of the intelligent switching device 100 is shown, Figure 2 a circuit principle diagram of the intelligent switching device 100 is shown, the intelligent switching device 100 comprises: a water collecting well 110, a control box 120, a plurality of gates 130, a plurality of liquid level control modules 140 and a water quality control module 150; the water collecting well 110 located at the end of the rainwater pipe of the factory is connected with the initial rainwater collection pool, the sponge pool and the municipal rainwater pipe network through different connecting pipelines; each first end of the connecting pipeline is provided with a gate 130; each liquid level control module 140 is arranged in the initial rainwater collection pool and the sponge pool; the water quality control module 150 is arranged in the initial rainwater collection pool; each gate 130, the liquid level control module 140 and the water quality control module 150 are electrically connected with the control box 120.

[0029] In this embodiment, the water collecting well 110 is poured with impermeable concrete, and is connected with the end of the rainwater pipe of the factory, Figure 1The middle arrow direction represents the water flow direction, and the rainwater flows into the water collecting well 110 through the rainwater pipe in the factory area for collection. The water collecting well 110 is connected with the initial rainwater collecting pool, the sponge pool and the municipal rainwater pipe network through different connecting pipes. Specifically, the water collecting well 110 is connected with the initial rainwater collecting pool through the first connecting pipe, connected with the sponge pool through the second connecting pipe, and connected with the municipal rainwater pipe network through the third connecting pipe. The first end of each connecting pipe is provided with a gate 130. The control box 120 is electrically connected with each liquid level control module 140, water quality control module 150 and each gate 130. The liquid level control module 140 is used for monitoring the water level and sending the water level information to the control box 120, and the water quality control module 150 is used for monitoring the pollutant concentration and sending the pollutant concentration information to the control box 120.

[0030] In the embodiment, the rainwater collection is divided into the following stages: the first stage is the initial rainwater collection stage. The control box 120 controls the gate 130 on the first connecting pipe to be opened, and the gates 130 on the second connecting pipe and the third connecting pipe to be closed. Thus, after the rainwater enters the water collecting well 110, it flows into the rainwater collecting pool through the first connecting pipe for collection. At the same time, the liquid level control module 140 in the initial rainwater collecting pool monitors the water level in the initial rainwater collecting pool in real time, and the water quality control module 150 monitors the rainwater pollution concentration in the initial rainwater collecting pool in real time. When the water level in the rainwater collecting pool reaches the preset water level height, or the rainwater pollution concentration in the initial rainwater collecting pool decreases to the preset concentration threshold, the control box 120 controls the gate 130 on the first connecting pipe to be closed, the gate 130 on the second connecting pipe to be opened, and the gate 130 on the third connecting pipe to remain in the closed state. At this time, the second stage of rainwater collection is entered.

[0031] In the second stage of rainwater collection, after the rainwater enters the water collecting well 110, it flows into the sponge pool through the second connecting pipe for collection. At the same time, the liquid level control module 140 in the sponge pool monitors the water level in the sponge pool in real time. When the water level in the sponge pool reaches the preset water level height, the control box 120 controls the gate 130 on the second connecting pipe to be closed, the gate 130 on the third connecting pipe to be opened, and the gate 130 on the first pipe to remain in the closed state. At this time, the third stage of rainwater collection is entered.

[0032] In the third stage of rainwater collection, after the rainwater enters the water collecting well 110, it flows into the municipal rainwater pipe network through the third connecting pipe for collection. Thus, the rainwater and sewage are collected by separate flow.

[0033] It should be noted that the control box 120 also has a cloud data synchronization function, which is used for storing historical data and forming a work log.

[0034] In an embodiment, the bottom of the water collecting well 110 is lower than the bottom of the factory rainwater pipe and the connecting pipes by a first preset distance.

[0035] In the present embodiment, the elevation of the pipe refers to the height of the bottom end of the pipe relative to the reference ground. The bottom of the water collecting well 110 is lower than the bottom of the factory rainwater pipe and the connecting pipes by a first preset distance, thereby achieving sand and mud collection and avoiding pipe blockage.

[0036] For example, please refer to Figure 3 , Figure 3 A side view of the intelligent switching device 100 is shown, where ΔH represents the first preset distance, for example, 0.8 m.

[0037] In an embodiment, the bottom of the water collecting well 110 is inclined at a preset angle relative to the reference ground.

[0038] In the present embodiment, the bottom of the water collecting well 110 has a certain slope, and the specific slope value can be set according to actual needs, for example, 5‰. Such a slope setting aims to guide the water flow to converge, thereby forming a sand pit at the bottom of the well. The main function of this sand pit is to deposit impurities such as sand, effectively preventing these impurities from entering the subsequent pipe system, avoiding pipe blockage, and ensuring smooth water flow. The volume of the sand pit can be flexibly set according to actual use requirements and site conditions to meet different application scenarios. In the present case, in order to ensure sufficient deposition capacity, the volume of the sand pit is set to be not less than 0.5 cubic meters (≥0.5 m 3 ). Such a design not only effectively collects and deposits sand, but also to some extent reduces the workload of subsequent cleaning and maintenance, improving the operation efficiency and reliability of the entire water collecting system.

The filter grid 160 can be replaced according to actual needs, and the pore size of the filter grid can also be selected according to actual needs, for example, the pore size is selected to be 10-20 mm.

The control box 120 comprises an editable control unit for adjusting the opening and closing state of each gate 130 according to the collected sensor data to realize rainwater and sewage separation. Specifically, for example, when the control box 120 determines that the rainwater in the initial rainwater collection tank meets the following conditions according to the collected sensor data: turbidity < 30 scattering turbidity units (NTU, Nephelometric Turbidity Unit) for 5 minutes and conductivity is stable within a fluctuation band of ± 3%, the control box 120 controls the gate 130 on the first connecting pipeline to be closed and the gate 130 on the second connecting pipeline to be opened, so that the rainwater flows into the sponge pool.
