Description

Technical Field

[0001] This invention relates to the field of sponge city technology, and in particular to a building drainage system for sponge city planning. Background Technology

[0002] Sponge city is a new generation of urban stormwater management concept, referring to a city that can be as resilient as a sponge in adapting to environmental changes and coping with natural disasters caused by rainwater. It can also be called a "water-resilient city." The core of sponge city is to start from ecosystem services, build water ecological infrastructure across scales, and combine various specific technologies to construct water ecological infrastructure. Under the new circumstances, sponge city is an innovative manifestation of promoting green building construction, low-carbon city development, and smart city formation. It is an organic combination of modern green new technologies with social, environmental, and humanistic factors under the characteristics of the new era.

[0003] In existing sponge city technologies, surface water is discharged into sewer pipes through wells and then transported to water purification devices for purification to meet standards before being stored or discharged. However, the impurity content of water entering the sewer pipes varies depending on the region, environment, and time of day. If a uniform purification process is applied, it would be a huge waste of resources. What was originally a simple filtration process would now require a complex purification process after mixing. Summary of the Invention

[0004] The purpose of this invention is to provide a comprehensive building drainage system for sponge city planning, which has the advantages of selectively using different filtration devices for pretreatment of sewage with different components, thereby saving costs and improving efficiency.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0006] A comprehensive building drainage system for sponge city planning includes: a roof drainage subsystem installed on the building roof, a ground drainage subsystem installed on the ground surface, an underground circulation and purification subsystem, a monitoring subsystem, and a main control subsystem.

[0007] The roof drainage subsystem includes a roof drainage structure and a roof drainage pipe installed on the roof of the building. The roof drainage structure is connected to the circulating purification subsystem through the roof drainage pipe. When the water accumulation on the roof exceeds a preset amount, the roof drainage structure opens to discharge the accumulated water into the circulating purification subsystem through the roof drainage pipe.

[0008] The circulating purification subsystem includes a purification device, a water storage device, a drainage device, and connecting pipes. The purification device, water storage device, and drainage device are connected to the ground drainage subsystem and the roof drainage subsystem through the connecting pipes.

[0009] The ground drainage subsystem includes a ground drainage outlet and a ground drainage pipeline. The ground drainage outlet is used to supply ground water to enter the circulating purification subsystem through the ground drainage pipeline. The ground drainage pipeline is equipped with a multi-stage filtration device to filter impurities of different standards.

[0010] The monitoring subsystem includes a ground monitoring module, which is installed at the ground drainage outlet to monitor the impurities in the accumulated water.

[0011] The ground monitoring module, multi-stage filtration device, and purification device are all electrically connected to the main control subsystem.

[0012] Further configuration: The drainage pipe includes an upper pipe section wall and a lower pipe section wall. Several stepped filtration areas are formed on the lower pipe section wall. The multi-stage filtration device includes several purification units, each corresponding to one of the filtration areas. Each purification unit includes a filter rotating plate and a drive mechanism for rotating the filter rotating plate. The filter rotating plate has a filtration state and a closed state. When the filter rotating plate is in the filtration state, it is used to filter impurities in the water. At this time, the side of the filter rotating plate away from the filtration area abuts against the upper pipe section wall. Each filter rotating plate and its corresponding filtration area form multiple independent filtration chambers. When the filter rotating plate is in the closed state, it covers the top of the filtration area. At this time, the filter rotating plate forms a water flow channel between the upper pipe section wall and the filter rotating plate.

[0013] Further configuration: The filter plate has a unidirectional filtration structure, and several filter plates are used to filter impurities with different particle diameters, and the particle diameter filtered along the flow direction of the accumulated water continuously decreases.

[0014] Further configuration: The main control subsystem includes a filtration adjustment module. The filtration adjustment module acquires component data collected by the monitoring module at preset sampling intervals, analyzes the component data to obtain impurity information, and controls the corresponding filter plate to be in the filtration state according to the impurity information, while the other filter plates are in the closed state. The impurity information includes the type of impurity and the particle diameter.

[0015] Further configuration: The unidirectional filtration structure includes a plurality of unidirectional holes formed on the filter rotating plate, and a baffle cover is rotatably connected to one side of one of the unidirectional holes. When the filter rotating plate is in the filtration state, the baffle cover is on the side in which the water flows; when the filter rotating plate is in the closed state, the baffle cover is located above the filter rotating plate.

[0016] Further configuration: The top drainage structure includes a drain outlet, a drain valve, and a liquid level detection module. The liquid level detection module is used to detect the depth of water accumulation. When the preset depth is reached, it controls the drain valve to open so that the water can be discharged into the circulating purification subsystem through the top drainage pipe.

[0017] Further configuration: The monitoring subsystem also includes a top monitoring module, which is installed inside the top drainage pipe and is used to monitor the flow data in the top drainage pipe and send it to the main control subsystem. The main control subsystem also includes an early warning module, which receives the flow data sent by the top monitoring module and generates an early warning signal when the water flow through the top drainage pipe exceeds a preset threshold within a preset unit period. After the monitoring subsystem detects the generation of the early warning signal, it controls all filter plates to be in a closed state.

[0018] Further configuration: A debris collection box is also provided below the ground drainage pipe. The filtration area includes a side wall and a bottom wall. An outlet is provided at the bottom wall. A debris removal mechanism is provided at the outlet. The debris removal mechanism includes a debris removal pipe, a debris removal plate rotatably connected to the outlet, and a power source mechanism for driving the debris removal plate to rotate. When the filter plate is in a closed state, the power source mechanism drives the debris removal plate to flip downward so that the debris in the filtration area enters the debris collection box through the debris removal pipe.

[0019] Further configuration: A rinsing mechanism is also provided on the side wall. The rinsing mechanism includes a water storage chamber and a rinsing nozzle. The rinsing nozzle is connected to the water storage chamber and is used to spray water from the water storage chamber onto the filter plate.

[0020] Further configuration: A water inlet is provided on the side wall, connecting the filtration area and the water storage chamber, and a filter screen is provided at the water inlet.

[0021] In summary, the present invention has the following beneficial effects: the top drainage subsystem and the ground drainage subsystem are respectively used to drain water from the top of the building and the ground. When rainwater enters the ground drainage outlet after passing through the complex environment of the ground, it contains different impurities and components. The ground monitoring module installed at the ground drainage outlet detects the composition of impurities in the water. The filtration adjustment module acquires the composition data collected by the ground monitoring module at preset sampling intervals, analyzes the composition data to obtain impurity information, and controls the corresponding filter plate to be in the filtration state according to the impurity information, while the other filter plates are in the closed state. That is, the filter plates for filtering impurities of corresponding particle diameters are opened according to the different impurity components contained in the water to filter the accumulated water. After the accumulated water flows through the filtration chambers, the water from different areas and times can reach a similar level after this pretreatment and then enter the purification device for purification, saving costs. At the same time, since the detection and treatment are carried out at each ground drainage outlet, the targeted filtration operation improves the efficiency of water flow. The top monitoring module is set up to monitor the water accumulation on the rooftop of the building in real time. Since the situation on the rooftop is often relatively simple and straightforward, rainwater tends to accumulate more quickly during sudden heavy rainfall and be discharged through the top drainage pipes. However, the ground surface is more complex and has a large number of facilities and vegetation to prevent water accumulation, so water accumulation is less likely to occur. But once water accumulates, it is often difficult to deal with in time. Therefore, the flow rate in the top drainage pipe per unit time is used as an alarm. When it exceeds the normal data, it means that the short-term rainfall in the area is too large, generating an early warning signal. The control device can promptly adjust the filter plates in the corresponding area's ground drainage pipes to a closed state, so that a water flow channel is formed between the filter plates and the upper pipe wall, maximizing the rapid flow of water and preventing blockages that could cause ground water accumulation.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Example:

[0029] like Figure 1-4 As shown, a building drainage system for sponge city planning includes: a roof drainage subsystem installed on the building roof, a ground drainage subsystem installed on the ground surface, an underground circulation and purification subsystem, a monitoring subsystem, and a main control subsystem.

[0030] The roof drainage subsystem includes a roof drainage structure 1 and a roof drainage pipe 2 installed on the roof of the building. The roof drainage structure 1 is connected to the circulation purification subsystem through the roof drainage pipe 2. When the water accumulation on the roof exceeds a preset amount, the roof drainage structure 1 is opened to discharge the accumulated water into the circulation purification subsystem through the roof drainage pipe.

[0031] The circulating purification subsystem includes a purification device 3, a water storage device 4, a drainage device 5, and a connecting pipe 6. The purification device 3, the water storage device 4, and the drainage device 5 are connected to the ground drainage subsystem and the roof drainage subsystem through the connecting pipe 6.

[0032] The ground drainage subsystem includes a ground drainage outlet 7 and a ground drainage pipe 8. The ground drainage outlet 7 is used to supply ground water to enter the circulating purification subsystem through the ground drainage pipe 8. The ground drainage pipe 8 is equipped with a multi-stage filtration device for filtering impurities of different standards.

[0033] The monitoring subsystem includes a ground monitoring module, which is installed at the ground drainage outlet 7 to monitor the impurities in the accumulated water.

[0034] The ground monitoring module, multi-stage filtration device, and purification device 3 are all electrically connected to the main control subsystem.

[0035] The ground drainage pipe 8 includes an upper pipe section wall 81 and a lower pipe section wall 82. Several stepped filtration areas 83 are formed on the lower pipe section wall 82. The multi-stage filtration device includes several purification units, each corresponding to one of the filtration areas 83. Each purification unit includes a filter rotating plate 84 and a drive mechanism for rotating the filter rotating plate 84. The filter rotating plate 84 has a filtering state and a closed state. When the filter rotating plate 84 is in the filtering state, it is used to filter impurities in the water. At this time, the side of the filter rotating plate 84 away from the filtration area 83 abuts against the upper pipe section wall 81. Each filter rotating plate 84 and the corresponding filtration area 83 form multiple independent filtration chambers 85. When the filter rotating plate 84 is in the closed state, the filter rotating plate 84 covers the top of the filtration area 83. At this time, the filter rotating plate 84 forms a water flow channel 86 between the upper pipe section wall 81.

[0036] The filter plate 84 has a unidirectional filtration structure. Several filter plates 84 are used to filter impurities with different particle diameters, and the particle diameter filtered along the flow direction of the accumulated water continuously decreases.

[0037] The main control subsystem includes a filtration adjustment module. The filtration adjustment module acquires component data collected by the monitoring module at preset sampling intervals, analyzes the component data to obtain impurity information, and controls the corresponding filter plate 84 to be in the filtration state according to the impurity information, while the other filter plates 84 are in the closed state. The impurity information includes the type of impurity and the particle diameter.

[0038] The unidirectional filtration structure includes a plurality of unidirectional holes formed on the filter rotating plate 84. A baffle is rotatably connected to one side of one of the unidirectional holes. When the filter rotating plate 84 is in the filtration state, the baffle is on the side in which the water flows. When the filter rotating plate 84 is in the closed state, the baffle is located above the filter rotating plate 84.

[0039] The top drainage structure 1 includes a drain outlet, a drain valve, and a liquid level detection module. The liquid level detection module is used to detect the depth of water accumulation. When the preset depth is reached, it controls the drain valve to open so that the water can be discharged into the circulating purification subsystem through the top drainage pipe.

[0040] The monitoring subsystem also includes a top monitoring module, which is installed inside the top drainage pipe and is used to monitor the flow data in the top drainage pipe and send it to the main control subsystem. The main control subsystem also includes an early warning module, which receives the flow data sent by the top monitoring module and generates an early warning signal when the water flow through the top drainage pipe exceeds a preset threshold within a preset unit period. After the monitoring subsystem detects the generation of the early warning signal, it controls all filter plates 84 to be in a closed state.

[0041] Below the ground drainage pipe 8, there is also an impurity collection box 9. The filtration area 83 includes a side wall and a bottom wall. An outlet is provided at the bottom wall. An impurity removal mechanism is provided at the outlet. The impurity removal mechanism includes an impurity removal pipe 10, an impurity removal plate 11 rotatably connected to the outlet, and a power source mechanism for driving the impurity removal plate 11 to rotate. When the filter rotating plate 84 is in a closed state, the power source mechanism drives the impurity removal plate 11 to flip downward so that the impurities in the filtration area 83 enter the impurity collection box 9 through the impurity removal pipe 10.

[0042] A rinsing mechanism is also provided on the side wall. The rinsing mechanism includes a water storage chamber 13 and a rinsing nozzle 12. The rinsing nozzle 12 is connected to the water storage chamber 13 and is used to spray the water in the water storage chamber 13 onto the filter plate 84.

[0043] A water inlet is provided on the side wall, connecting the filtration area 83 and the water storage chamber 13, and a filter screen is installed at the water inlet. The water in the filtration area 83 is used as the water source for rinsing the filter plate 84, which saves water resources. At the same time, the filter screen prevents impurities in the water from entering the water storage chamber 13 and causing clogging of the rinsing mechanism.

[0044] The set-up top drainage subsystem and ground drainage subsystem are used to drain water accumulated on the top and ground of the building, respectively. After passing through the complex environment of the ground, rainwater enters the ground drainage outlet 7 with different impurities and components. The ground monitoring module set in the ground drainage outlet 7 detects the composition of impurities in the water. The filtration adjustment module obtains the composition data collected by the ground monitoring module at preset sampling intervals, analyzes the composition data to obtain impurity information, and controls the corresponding filter plate 84 to be in the filtration state according to the impurity information, while the other filter plates 84 are in the closed state. That is, the filter plates 84 that filter impurities of corresponding particle diameters are opened according to the different impurity components contained in the water to filter the accumulated water. After the accumulated water flows through the filtration chambers 85, the water in different areas and at different times can reach a similar level after this pretreatment and then enter the purification device 3 for purification, saving costs. At the same time, since the detection and treatment are carried out at each ground drainage outlet 7, the targeted filtration operation improves the efficiency of water passage. The top monitoring module is set up to monitor the water accumulation on the rooftop of the building in real time. Since the situation on the rooftop is usually relatively simple and straightforward, rainwater tends to accumulate more quickly on the rooftop during sudden heavy rainfall and is discharged through the top drainage pipe. The ground surface is more complex and has a large number of facilities and vegetation to prevent water accumulation, so water accumulation is less likely to occur. However, once water accumulates, it is often difficult to deal with in time. Therefore, the flow rate in the top drainage pipe per unit time is used as an alarm. When it exceeds the normal data, it means that the short-term rainfall in the area is too large, generating an early warning signal. The control device can adjust the filter plates 84 in the corresponding area's ground drainage pipe 8 to the closed state in time, so that a water flow channel 86 is formed between the filter plates 84 and the upper pipe section wall 81, maximizing the rapid flow of water and avoiding blockage and ground water accumulation.

[0045] The embodiments described above do not constitute a limitation on the scope of protection of this technical solution. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the above embodiments should be included within the scope of protection of this technical solution.
