[0001] This invention relates to a rainwater and sewage separation device, and more particularly to a rainwater and sewage separation automatic control device and its installation method, belonging to the field of drainage technology. Background Technology

[0002] Currently, oil stains from street-front restaurants, daily road dust, and illegal discharges from businesses are major sources of pollution in the stormwater drainage network. Street-front restaurants and night market stalls discharge oil stains into nearby road rainwater collection systems. Road dust and impurities are also major pollutants in the early stages of rainwater runoff and are one aspect that needs to be addressed. Illegal discharges also occur frequently, with businesses or merchants illegally discharging industrial wastewater or domestic sewage into stormwater pipes.

[0003] Most cities have rainwater and sewage separation designs for sewage discharge. Rainwater and sewage separation is a drainage system design that treats rainwater and sewage separately. Its core is to collect and transport rainwater and sewage separately through independent pipe networks. The advantages of this model are mainly reflected in environmental protection, resource utilization, urban management and other aspects.

[0004] However, traditional rainwater and sewage separation requires the laying of separate pipes, which wastes resources and requires significant investment in subsequent maintenance, leading to increased maintenance costs.

[0005] Therefore, it is urgent to improve the automatic control device for rainwater and sewage separation in order to solve the above-mentioned problems. Summary of the Invention

Under the action of the detection mechanism, the water quality is detected. At the same time, the water is intercepted by the valve assembly so that rainwater or sewage can flow out separately, realizing the cascade utilization of water resources.

[0009] Preferably, a water collection mechanism is fixedly installed inside the detection box.

The piston is slidably disposed inside the detection box. The piston has a detection groove on its upper side, and a water quality detection sensor is fixedly installed inside the detection groove. The electric telescopic rod and the water quality detection sensor are both connected to the central processing unit.

An impeller is provided at the output end of the generator.

[0011] Preferably, a filter screen is fixedly installed on the peripheral side of the generator, and a secondary filter screen and a main filter screen are fixedly installed on the filter screen. The filter screen is fixedly installed on the water inlet valve by screws.

[0012] Preferably, a first neodymium magnet is fixedly disposed on one side of the sealing plate, and a second neodymium magnet is fixedly disposed at the port of the drain outlet, wherein the magnetic properties of the first neodymium magnet and the second neodymium magnet are opposite on the side closest to each other.

[0013] Preferably, an assembly plate is fixedly provided on one side of each of the water inlet valve, the sewage valve, and the rainwater valve. The assembly plate has a plurality of assembly holes, which are fixed inside the drainage tee well by expansion bolts.

[0014] Preferably, the bottom of the distribution box is fixedly provided with box support feet, which are fixedly installed inside the well shaft of the drainage tee well.

[0015] Preferably, a sealing plate groove is provided on one side of each of the water inlet valve, the sewage valve, and the rainwater valve, and the sealing plate is rotatably disposed inside the sealing plate groove; A cleaning rod is connected to the sealing plate, and the cleaning rod is rotatably disposed inside the rotating groove of the sealing plate.

[0016] An installation method for a rainwater and sewage separation automatic control device includes the following steps: Step 1: Filter screen installation. First, fix the generator to the water inlet valve using the generator mounting bracket. Then, fix the filter screen to the water inlet valve with screws to complete the filter screen installation. Step 2: Valve installation. Install the inlet valve inside the inlet pipe using the mounting plate, the sewage valve inside the sewage pipe, and the rainwater valve inside the rainwater pipe. Step 3: Installation of the testing mechanism. The testing mechanism is fixedly installed inside the drainage tee well using the box support feet. Step 4: Communication connection.

[0017] The present invention has at least the following beneficial effects: 1. The drainage tee well is equipped with an inlet pipe, a sewage pipe, and a rainwater pipe. This means that both rainwater and sewage can be discharged into the drainage tee well. The water quality is tested by a testing agency, and the water is intercepted by a valve assembly so that rainwater or sewage can flow out separately. If the test results are not up to standard in sunny or rainy weather, the rainwater valve inside the rainwater pipe is closed and the sewage valve inside the sewage pipe is opened, and the sewage is discharged from the sewage pipe. The sewage is then transported to the treatment plant through a dedicated pipeline. After deep treatment, it can meet the standards for reuse as greywater for industrial cooling, toilet flushing, etc., realizing the cascade utilization of water resources. If the rainwater meets the testing standards of the testing agency, the sewage valve in the sewage pipe is closed and the rainwater valve in the rainwater pipe is opened, and the rainwater is discharged from the rainwater pipe. Therefore, rainwater or sewage can flow out separately, saving a lot of paving materials. The independently collected rainwater can be used for non-potable water scenarios such as greening irrigation, road washing, and landscape water replenishment after simple treatment, which can alleviate the problem of urban water shortage.

[0018] 2. The inlet valve, sewage valve, and rainwater valve are all equipped with sealing plates that are rotated by a sealing plate motor. When the sealing plate covers the drain outlet, it is in a closed state. When the sealing plate rotates to the top of the drain outlet, it is in an open state. Therefore, the structure is simple and can control the opening and closing of the sewage pipe and rainwater pipe at any time.

[0019] 3. After water enters the distribution box, the water quality is detected by a water quality sensor. The sensor transmits the detected information to the central processing unit, which processes it. The central processing unit then transmits the processed information wirelessly to the data center via a communication module, collecting water quality data in real time and accurately distributing it.

Detailed Implementation

[0022] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0023] like Figures 1-12 As shown, the rainwater and sewage separation automatic control device provided in this embodiment includes a water control mechanism 10 installed inside the drainage tee well 1. The water control mechanism 10 includes a valve assembly 2 and a detection mechanism 3. Currently, most cities have rainwater and sewage separation designs for sewage discharge. Rainwater and sewage separation is a drainage system design that separates rainwater and sewage for treatment. Its core is to collect and transport rainwater and sewage separately through independent pipe networks. The advantages of this mode are mainly reflected in environmental protection, resource utilization, urban management and other aspects. However, rainwater and sewage separation requires laying independent pipes, which wastes resources and requires a lot of investment. It also requires separate maintenance in the later stage, which increases the maintenance cost. The well of this invention is a tee well, which integrates the collection of sewage and rainwater, avoiding the waste of resources caused by laying independent pipes. At the same time, maintenance is also simple and quick. Valve assembly 2 includes an inlet valve 201, a sewage valve 202, and a rainwater valve 203. Drainage tee well 1 includes an inlet pipe 101, a sewage pipe 102, and a rainwater pipe 103. The inlet valve 201 is fixedly installed at the port of the inlet pipe 101, the sewage valve 202 is fixedly installed inside the sewage pipe 102, and the rainwater valve 203 is fixedly installed inside the rainwater pipe 103. The drainage tee well 1 is equipped with an inlet pipe 101, a sewage pipe 102, and a rainwater pipe 103, which means that both rainwater and sewage can be discharged into the drainage tee well 1. The water quality is detected by the detection mechanism 3, and the water is intercepted by the valve assembly 2 so that rainwater or sewage can flow out separately. For example, such as Figure 10 As shown, if the test indicators of the testing agency 3 fail to meet the standards in sunny or rainy weather, the rainwater valve 203 inside the rainwater pipe 103 is closed, and the sewage valve 202 inside the sewage pipe 102 is opened. The sewage will then be discharged from the sewage pipe 102 and transported to the treatment plant through a dedicated pipeline. After deep treatment, the sewage can meet the standards for reuse as greywater and can be used for industrial cooling, toilet flushing, etc., thus realizing the cascade utilization of water resources. like Figure 10 As shown, when the rainwater testing agency 3 tests the indicators and they are qualified, the sewage valve 202 in the sewage pipe 102 is closed and the rainwater valve 203 in the rainwater pipe 103 is opened. Rainwater is then discharged from the rainwater pipe 103. Therefore, rainwater or sewage can flow out separately, saving a lot of paving materials. The independently collected rainwater can be used for non-potable water scenarios such as greening irrigation, road washing, and landscape water replenishment after simple treatment, which can alleviate the problem of urban water shortage. During the drainage process, a sealing plate motor 204 is fixedly installed in the middle of the inlet valve 201, sewage valve 202 and rainwater valve 203. A drain outlet 205 is opened below the sealing plate motor 204. A sealing plate 206 is installed at the output end of the sealing plate motor 204. The sealing plate 206 is used to seal the drain outlet 205. The sealing plate 206 is installed on the inlet valve 201, sewage valve 202 and rainwater valve 203 through the rotation of the sealing plate motor 204. When the sealing plate 206 covers the drain outlet 205, it reaches the closed state. When the sealing plate 206 rotates to the top of the drain outlet 205, it is in the open state. Therefore, the structure is simple and can control the opening and closing of the sewage pipe 102 and the rainwater pipe 103 at any time. During the testing process, the testing mechanism 3 includes a power distribution box 301 and a testing box 302. The power distribution box 301 is internally equipped with a central processing unit 303 and a battery 304 that are electrically connected. The central processing unit 303 and the battery 304 are located inside the power distribution box 301 and can play a certain sealing role, thereby improving the service life of the central processing unit 303 and the battery 304. The sealing plate motor 204 and the testing box 302 are both connected to the central processing unit 303. The sealing plate motor 204 is connected to the central processing unit 303 and can be directly controlled to make the sealing plate 206 rotate, thereby improving the ease of use. After closing the inlet valve 201, sewage valve 202, and rainwater valve 203, the testing box 302 tests the water quality, specifically as follows: Pumping: A water collection mechanism 4 is fixedly installed inside the detection box 302. The water collection mechanism 4 includes an electric telescopic rod 401. A piston 402 is installed at the output end of the electric telescopic rod 401. The piston 402 is slidably installed inside the detection box 302. A water inlet hole 306 communicating with the detection box 302 is opened on the upper side of the detection box 302. By starting the electric telescopic rod 401, the piston 402 is pulled down, and water enters the inside of the distribution box 301 from the water inlet hole 306. Detection: A detection groove 403 is provided on the upper side of the piston 402. A water quality detection sensor 404 is fixedly installed inside the detection groove 403. After water enters the power distribution box 301, the water quality is detected by the water quality detection sensor 404. Both the electric telescopic rod 401 and the water quality detection sensor 404 establish a communication connection with the central processing unit 303. The water quality detection sensor 404 transmits the detected information to the central processing unit 303, which processes it. A communication module 305 is fixedly installed on the upper side of the detection box 302. The communication module 305 establishes a communication connection with the central processing unit 303. The communication module 305 is wirelessly connected to the data center. After processing the information, the central processing unit 303 transmits it wirelessly to the data center through the communication module 305, collecting water quality data in real time for accurate diversion. like Figure 12 As shown, a valve operation fault analysis model is constructed based on big data technology to accurately determine fault conditions and issue timely alarms. The data center includes a monitoring center, which consists of an industrial control computer and an IoT card. The industrial control computer is connected to a display screen and a printer. The IoT card establishes a wireless communication connection with the WeChat platform. Automatic report generation technology is used to automatically generate daily, monthly, and detailed reports of detection data and automatically calculate the diversion situation. Modern information and communication technology is used to construct a water quality monitoring cloud platform to intuitively display water quality detection data in a graphical manner. Reports are published in the cloud, allowing users to view water quality monitoring status anytime, anywhere, view and download reports, and simultaneously support multiple alarm methods: SMS, WeChat, etc., to promptly send alarm information to the responsible persons. It adopts LoRa wireless self-organizing network technology, dual-channel transmission, no wiring required, flexible networking, and reliable transmission.

[0024] Drainage: After the test is completed, the electric telescopic rod 401 is activated to push the piston 402 upward, and the tested water is discharged through the water inlet 306, thus completing the water quality test.

[0025] Furthermore, such as Figure 6 and Figure 7As shown, a generator 5 is fixedly installed on the side of the water inlet valve 201 away from the sealing plate 206. The generator 5 establishes a communication connection with the central processing unit 303. The generator 5 is fixedly installed on the water inlet valve 201 through the generator mounting bracket 501. An impeller 502 is provided at the output end of the generator 5. The generator 5 is fixedly installed on the water inlet valve 201 at the port of the water inlet pipe 101. The impeller 502 is driven to rotate by the water flow, thereby making the generator 5 generate electricity and transmitting the generated electrical energy to the central processing unit 303 and storing it in the battery 304. Therefore, it can reduce the consumption of electrical energy and improve the utilization rate of resources. In addition, to protect generator 5 and extend its service life, such as... Figure 1 As shown, a filter screen 6 is fixedly installed on the periphery of the generator 5. A secondary filter screen 601 and a main filter screen 602 are fixedly installed on the filter screen 6. The filter screen 6 is fixedly installed on the water inlet valve 201 by screws. The filter screen 6 is fixedly installed on the water inlet valve 201. The filter screen 6 filters impurities in the water, thereby improving the service life of the generator 5.

[0026] Furthermore, such as Figure 7 As shown, a first neodymium magnet 7 is fixedly installed on one side of the sealing plate 206, and a second neodymium magnet 701 is fixedly installed at the port of the drain outlet 205. The magnetic properties of the first neodymium magnet 7 and the second neodymium magnet 701 are opposite on the side closest to each other. The first neodymium magnet 7 is fixedly installed on the sealing plate 206 and corresponds to the second neodymium magnet 701 on the drain outlet 205. Due to the interaction force between the magnetic poles, the stability of the sealing plate 206 can be improved to a greater extent, and the sealing effect can be improved. Furthermore, a sealing plate groove 209 is provided on one side of the inlet valve 201, the sewage valve 202, and the rainwater valve 203. The sealing plate 206 is rotatably disposed inside the sealing plate groove 209. The rotatable disposal of the sealing plate 206 inside the sealing plate groove 209 can also improve the stability of the sealing plate 206. A cleaning rod 210 is connected to the sealing plate 206. The cleaning rod 210 is rotatably disposed inside the sealing plate groove 209. At the same time, the cleaning rod 210 on the sealing plate 206 can clean the impurities inside the sealing plate groove 209 and improve the rotational stability of the sealing plate 206.

[0027] Furthermore, such as Figure 7 and Figure 8As shown, an assembly plate 207 is fixedly installed on one side of each of the inlet valve 201, sewage valve 202, and rainwater valve 203. Several assembly holes 208 are provided on the assembly plate 207. The assembly holes 208 are fixed inside the drainage tee well 1 by expansion bolts. The inlet valve 201, sewage valve 202, and rainwater valve 203 are all fixedly installed on the drainage tee well 1 by the assembly plate 207, which improves the overall stability of the valve assembly 2. The bottom of the distribution box 301 is fixedly provided with a box support foot 307. The box support foot 307 is fixedly installed inside the well shaft of the drainage tee well 1. The distribution box 301 is fixed inside the well shaft of the drainage tee well 1 by the box support foot 307, which improves the stability of the distribution box 301.

[0028] like Figures 1-12 As shown, the installation method of the rainwater and sewage separation automatic control device provided in this embodiment is as follows: Figure 1 As shown, it includes the following steps: Step 1: Install the filter screen. First, fix the generator 5 on the water inlet valve 201 using the generator mounting bracket 501. Then, fix the filter screen 6 on the water inlet valve 201 with screws to complete the installation of the filter screen 6. Step 2: Valve installation. Install the inlet valve 201 inside the inlet pipe 101 via the assembly plate 207, install the sewage valve 202 inside the sewage pipe 102, and install the rainwater valve 203 inside the rainwater pipe 103. Step 3: Installation of the detection mechanism. The detection mechanism 3 is fixedly installed inside the well shaft of the drainage tee well 1 using the box support feet 307. Step 4: Communication connection. Connect valve assembly 2 to detection mechanism 3 via wires, and establish communication connection between central processing unit 303 and data center via communication module 305.
