Description

Technical Field

[0001] This utility model belongs to the field of environmental protection and water supply and drainage engineering technology, and in particular relates to an intelligent control device for the liquid level of an initial rainwater storage tank. Background Technology

[0002] With the acceleration of urbanization and the frequent occurrence of extreme rainfall events, the collection, storage, and resource utilization of rainwater have become important issues in urban drainage system optimization and water environment protection. Promoting the effective collection, treatment, and resource utilization of initial rainwater can not only help alleviate urban flooding problems, but also significantly reduce the impact of pollutants in rainwater runoff on natural water bodies and improve the overall water environment quality.

[0003] Currently, the management of initial rainwater runoff has become increasingly standardized both domestically and internationally, with relevant standards and regulations generally including requirements for controlling the water quality of initial rainwater. In China, pollution control is typically achieved by setting water quality indicators or controlling the amount of initial rainwater collected. However, these measures still have certain limitations in practical application: on the one hand, the identification and classification of initial rainwater are not precise enough and lack specificity; on the other hand, management measures rely heavily on traditional engineering methods, such as constructing storage tanks and sedimentation tanks, lacking intelligent and automated control methods, making it difficult to achieve efficient classification, collection, and precise management of initial rainwater.

[0004] Therefore, there is a particular need for an intelligent control device for the liquid level of initial rainwater storage tanks to solve the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing initial rainwater management methods, such as inaccurate identification and unclear classification, reliance on traditional engineering measures, lack of intelligent and automated control capabilities, and difficulty in achieving efficient and accurate rainwater classification, collection, and pollution control, this utility model provides an intelligent control device for the liquid level of an initial rainwater storage tank.

[0006] This utility model is achieved through the following technical approach: an intelligent level control device for an initial rainwater storage tank, comprising a storage tank body, a cover plate, a water collection frame, a connecting pipe, a diversion pipe, an inlet pipe, an intelligent control component, a drainage pump, a drainage pipe, a partition, a level detector, and a control panel. The cover plate is installed on the upper part of the storage tank body and blocks the upper opening of the storage tank body. The partition is fixedly connected to the inside of the storage tank body, dividing the inside of the storage tank body into two independent water storage spaces. Two inlet pipes are arranged side by side and fixedly connected to one side of the lower part of the storage tank body, with each inlet pipe corresponding to one of the two water storage spaces. A diversion pipe is fixedly connected between one end of the two inlet pipes, and a diversion pipe is fixedly connected to the diversion pipe. The system includes a connecting pipe with a water collection frame fixed at one end. Two drainage pumps, distributed front to back, are installed on one side of the interior of the water storage tank. The two drainage pumps are located in two separate water storage spaces. A drainage pipe is fixed to the drainage end of each drainage pump, extending through the water storage tank to its exterior. Two level detectors, distributed front to back, are installed on the other side of the interior of the water storage tank. The two level detectors are located in two separate water storage spaces. A control panel is installed on the upper side of the water collection frame. The drainage pumps and level detectors are electrically connected to the control panel, which is waterproof. The intelligent control components are located between the water collection frame, the diversion pipe, the inlet pipe, the connecting pipe, and the drainage pipe.

[0007] Furthermore, the intelligent control component includes solenoid valve one, solenoid valve two, solenoid valve three, and a water quality detector. Solenoid valve one is installed at both ends of the diversion pipe, solenoid valve two is installed at one end of the diversion pipe, and solenoid valve three is installed at one end of each drain pipe. A water quality detector is installed inside the water collection frame. Solenoid valve one, solenoid valve two, solenoid valve three, and the water quality detector are all electrically connected to the control panel.

[0008] Furthermore, it also includes a connecting frame, photovoltaic panels, and a storage battery. The connecting frame is installed on the top of the water storage tank body, the photovoltaic panels are installed on the top of the connecting frame, and the storage battery is installed at the bottom of the photovoltaic panels. It is electrically connected to solenoid valve one, solenoid valve two, drainage pump, solenoid valve three, liquid level detector, water quality detector, and control panel.

[0009] Furthermore, it also includes a filter screen, which is fixed to the top of the water collection frame.

[0010] Furthermore, it also includes a protective box, which is fixed between one end of the two inlet pipes and covers the diversion pipe and the two solenoid valves.

[0011] Furthermore, the protective box is made of corrosion-resistant materials.

[0012] Beneficial effects: 1. The water storage tank is divided into two independent water storage spaces by a partition. Combined with a water quality detector to monitor the degree of rainwater pollution in real time, and with the help of solenoid valves one and two in the intelligent control component to realize the automatic conduction of the corresponding channels of the diversion pipe, rainwater is introduced into the corresponding water storage space through two inlet pipes. This effectively solves the problems of inaccurate identification, unclear classification and lack of targeting in traditional initial rainwater management, and realizes efficient classification, collection and precise management of rainwater with different pollution levels.

[0020] Example: An intelligent level control device for initial rainwater storage tanks, such as... Figures 1-5As shown, the system includes a water storage tank body 1, a cover plate 2, a water collection frame 3, a connecting pipe 4, a diversion pipe 5, an inlet pipe 6, an intelligent control component, a drainage pump 9, a drainage pipe 10, a partition 12, a liquid level detector 13, a control panel 15, and a filter screen 16. The cover plate 2 is bolted to the upper part of the water storage tank body 1 and blocks the upper opening of the water storage tank body 1 to prevent debris from entering. The partition 12 is fixedly connected to the inside of the water storage tank body 1, dividing the inside of the water storage tank body 1 into two independent water storage spaces. The water storage space located on the front side is used to collect initially heavily polluted rainwater, and the water storage space located on the rear side is used to collect later lightly polluted rainwater, realizing the classified storage of polluted rainwater. Two inlet pipes 6 are arranged side by side and fixedly connected to the lower left side of the water storage tank body 1. The two inlet pipes 6 correspond to the two water storage spaces respectively. A diversion pipe 5 is fixedly connected between the left ends of the two inlet pipes 6, and a connecting pipe 4 is fixedly connected to the diversion pipe 5. A water collection frame 3 is fixedly connected to the upper end of the connecting pipe 4. Two drainage pumps 9, distributed front and back, are bolted to the right side of the inside of the water storage tank body 1. The two drainage pumps 9 are located in two water storage spaces respectively. A drainage pipe 10 is fixedly connected to the drainage end of each drainage pump 9. The drainage pipe 10 passes through the water storage tank body 1 and extends to its outside. Two liquid level detectors 13, distributed front and back, are bolted to the left side of the inside of the water storage tank body 1. The two liquid level detectors 13 are located in two water storage spaces respectively to monitor water level changes in real time. The control panel 15 is bolted to the middle of the upper left side of the water collection frame 3. The drainage pumps 9 and the liquid level detectors 13 are electrically connected to the control panel 15. The control panel 15 is a waterproof control panel. The filter screen 16 is fixedly connected to the top of the water collection frame 3 to filter impurities such as leaves and pebbles in the rainwater. The intelligent control component is set between the water collection frame 3, the diversion pipe 5, the inlet pipe 6, the connecting pipe 4, and the drainage pipe 10.

[0021] like Figures 1-5 As shown, the intelligent control component includes solenoid valve 7, solenoid valve 8, solenoid valve 11, and water quality detector 14. A solenoid valve 7 is installed at both ends of the diversion pipe 5 to control rainwater to enter different inlet pipes 6 through the diversion pipe 5, and then be sent to different water storage spaces by the inlet pipes 6. A solenoid valve 8 is installed at the upper end of the diversion pipe 5, and a solenoid valve 11 is installed at the upper end of each drainage pipe 10. A water quality detector 14 is bolted inside the water collection frame 3 to detect the degree of pollution of the entering rainwater. Solenoid valves 7, 8, 11, and 14 are all electrically connected to the control panel 15 to realize the automatic control of the system.

[0022] like Figure 1 and Figure 2As shown, it also includes a connecting frame 17, a photovoltaic panel 18, and a storage battery 19. The connecting frame 17 is bolted to the top of the water storage tank body 1, the photovoltaic panel 18 is bolted to the top of the connecting frame 17, and the storage battery 19 is bolted to the bottom of the photovoltaic panel 18. It is also electrically connected to solenoid valve 7, solenoid valve 8, drainage pump 9, solenoid valve 11, liquid level detector 13, water quality detector 14, and control panel 15 to provide green energy support for the device.

[0023] like Figure 1 As shown, it also includes a protective box 20, which is fixedly connected between the left ends of the two water inlet pipes 6 and covers the diversion pipe 5 and the two solenoid valves 7 to provide protection. The protective box 20 is made of corrosion-resistant material, such as stainless steel, fiberglass or polyethylene, and can be exposed to rainwater for a long time without being damaged.

[0024] At the beginning of rainfall, rainwater is collected on the ground and enters the water collection frame 3. The filter screen 16 performs preliminary filtration of the rainwater to remove impurities such as leaves and stones. At the same time, the water quality detector 14 detects the pollution level of the rainwater in real time and transmits the data to the control screen 15.

[0025] According to the detection results of the water quality detector 14, the control panel 15 distributes the rainwater flow direction through the intelligent control component: when the rainwater is detected to be initially heavily polluted, the control panel 15 will automatically open the solenoid valve 2 8 and the front solenoid valve 1 7, and connect the front end of the connecting pipe 4 and the diversion pipe 5, so that the rainwater enters the front water storage space for storage through the connecting pipe 4, the front end of the diversion pipe 5 and the front water inlet pipe 6.

[0026] When the rainwater is detected to be slightly polluted in the later stage, the control panel 15 automatically opens the second solenoid valve 8 and the rear solenoid valve 7, and connects the rear end of the connecting pipe 4 and the diversion pipe 5, so that the rainwater enters the rear water storage space for storage through the connecting pipe 4, the rear end of the diversion pipe 5 and the rear inlet pipe 6.

[0027] During the process, the level detectors 13 in the two water storage spaces monitor the water level in real time and feed the data back to the control panel 15. When the water level in a certain water storage space reaches the preset threshold, the control panel 15 will automatically start the corresponding drainage pump 9 and open the solenoid valve 11 on the corresponding drainage pipe 10 to open the drainage pipe 10 and discharge rainwater through the drainage pipe 10 to the sewage treatment system or designated discharge point, thereby achieving automatic drainage and overflow protection.

[0028] The entire system is controlled by the control panel 15. All detectors and actuators are electrically connected to it, forming a closed-loop intelligent control system. At the same time, the device is equipped with a green power supply system consisting of photovoltaic panels 18 and batteries 19 to ensure normal operation in environments without mains power.
