Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically to a modular intelligent rainwater and sewage interception and conveying device. Background Technology

[0002] In the early stages of rainfall, rainwater washes debris from the roads into storm drains. However, storm drains can only intercept larger debris, resulting in a large amount of wastewater flowing into rivers and causing pollution. Therefore, the initial rainwater contains a high level of pollutants and requires effective treatment to prevent it from entering rivers.

[0003] After the initial rainwater washes over the roads to a certain extent, the subsequent rainwater becomes relatively cleaner with lower concentrations of pollutants, making it an important source of high-quality water for replenishing rivers and lakes. At this point, the clean rainwater in the storm drains is guided into the river channels.

[0004] The existing technologies have the following problems: 1. The quality of initial rainwater is affected by uncertain factors such as rainfall intensity, rainfall interval, and rainfall pattern, resulting in high uncertainty in the rainwater pollutant load. Effectively distinguishing whether rainwater should be intercepted and treated or diverted to rivers requires intelligent identification, interception, and classification treatment. 2. During heavy rainfall, if the equipment continues to discharge naturally when the rainfall volume is large, the treatment capacity may be insufficient, leading to water accumulation. 3. During heavy rainfall, equipment malfunctions, and traditional emergency repairs are labor-intensive, time-consuming, and uncertain, which can also affect the rainwater discharge effect. Utility Model Content

[0005] To address the shortcomings of the aforementioned technologies, this invention provides a modular intelligent rainwater and sewage interception and conveying device.

[0006] The technical solution of this utility model is as follows: A modular intelligent rainwater and sewage interception and conveying device includes an upstream inlet pipe, an outlet pipe, a sewage discharge pipe, a main housing, a power control cabinet, a flow detection module, and a water quality detection module. The main housing is provided with a treatment chamber, an inlet, an outlet, several grilles, and a cover. The inlet is connected to the upstream inlet pipe, which is connected to the municipal pipe network. The outlet is connected to the discharge pipe. The several grilles divide the bottom of the treatment chamber into several secondary chambers along the direction from the inlet to the outlet. The water quality detection module is set in each secondary chamber and is connected to the electro-hydraulic control cabinet. The flow detection module is set at the pipe network node and is connected to the power control cabinet.

[0007] Each of the secondary chambers is equipped with a sewage pump connected to the sewage pipeline. The electro-hydraulic control cabinet is connected to each sewage pump and controls each sewage pump to draw sewage through the sewage pipeline to the sewage treatment plant based on the signals from the flow detection module and the water quality detection module.

[0008] A further feature of this invention is that a forced-flow rainwater pump and a forced-flow pipeline are installed in the secondary chamber near the outlet. The forced-flow rainwater pump is connected to the forced-flow pipeline and is signal-connected to the power control cabinet. The power control cabinet controls the forced-flow rainwater pump to draw rainwater from the secondary chamber according to the signal from the flow detection module and discharges it to the discharge pipeline through the forced-flow pipeline.

[0009] Further features of this invention: The water quality detection module includes an ammonia nitrogen detector, a total phosphorus detector, and a COD detector.

[0010] Further features of this invention: the water inlet is detachably connected to the upstream water inlet pipe, the water outlet is detachably connected to the discharge pipe, the main housing is provided with several lifting lugs, and each secondary chamber of the main housing is provided with a cleaning pipe and a drain valve at its bottom.

[0011] A further feature of this utility model is that an expansion rubber sleeve is provided at the pipe opening where the upstream water inlet pipe, the discharge pipe connects to the water inlet and the water outlet. The outer circumferential surface of the expansion rubber sleeve is adapted to the pipe opening, and the inner hole is a tapered threaded hole. The expansion rubber sleeve is provided with a limiting flange that engages with the end face of the pipe opening.

[0012] The inlet and outlet are provided with internal threads. The device also includes a connecting flange, which is provided with a threaded shaft, a flange plate, and a water passage hole. The diameter of the threaded shaft is adapted to the internal thread and the tapered thread hole. The connecting flange is detachably connected to the upstream water inlet pipe and the discharge pipe through the inlet or outlet of the main box.

[0013] The beneficial effects of this utility model are as follows: First, through the design of the intelligent rainwater interception and transportation device, in the early stage of rainwater, the polluted rainwater collected by the municipal pipe network nodes enters the main tank through the upstream inlet pipe. The main tank is equipped with multiple screens to further filter the polluted rainwater and form multiple secondary chambers. In conjunction with the water quality detection modules in each secondary chamber, the changes in the rainwater quality after filtration are detected. The power control cabinet identifies the detection data (specifically, the detection values ​​of ammonia nitrogen, total phosphorus, COD, etc.) and controls the start of each sewage pump to intercept and extract the polluted rainwater, which is then transported to the sewage treatment plant for treatment through the sewage pipeline. This avoids the direct discharge of sewage with high pollutant content into the river in the early stage of rainwater.

[0014] Second, through the design of the flow detection module, the forced drainage rainwater pump, and the forced drainage pipeline, the power control cabinet identifies changes in upstream rainfall. During periods of increased rainfall, the forced drainage rainwater pump is started under the control of the power control cabinet to accelerate the drainage efficiency of the device and relieve upstream pressure.

[0015] Third, the device is modularly designed, utilizing improvements to the structure of the expansion rubber sleeve and connecting flange. During the screwing of the threaded shaft into the tapered threaded hole, the nozzle rubber sleeve expands radially, ensuring a tight connection with the pipe opening. This allows for detachable connections to upstream inlet and outlet pipelines. In the event of a fault that is difficult to resolve quickly due to heavy rainfall, the device can be rapidly disassembled, hoisted, and replaced with a new module, enabling complete module replacement and restoration, thus saving time during emergency repairs.

[0016] Fourth, on the one hand, installing this equipment can quickly solve the problems of regional sewage collection and sewage overflow into rivers; on the other hand, it can effectively collect initial rainwater, which is beneficial to river water environment management. Furthermore, due to its modular design, it can be modularly removed and reused in other areas after remediation is completed in the area or upstream, or used for enhanced monitoring in key areas. Through equipment numbering and remote communication monitoring, the usage trajectory and maintenance status of each module can be tracked, forming an intelligent management system of historical data.
