Description

Technical Field

[0001] This utility model belongs to the field of rainwater drainage technology, specifically relating to a real-time metering and display device for rainwater retention capacity in sponge facilities. Background Technology

[0002] With the acceleration of urbanization, rainwater drainage has become one of the important issues in urban management. Traditional urban drainage systems often rely on pipes and drainage ditches to quickly remove rainwater, resulting in rapid water loss and failure to fully utilize or treat rainwater resources. This rapid discharge method not only wastes water resources but also exacerbates environmental problems such as urban flooding, inundation, and water pollution. As an innovative urban water management concept, sponge cities have gradually gained widespread attention and application. The basic concept of sponge cities is to effectively collect, treat, and utilize rainwater through permeability, retention, infiltration, and purification, reduce urban rainwater loss, and enable water resources to be recycled in a natural way.

[0003] A prior art patent, CN211774126U, describes a rainwater collection and metering device. This device includes a tank with a first inlet hopper fixedly connected to the inner wall of the top. Electric push rods are fixedly connected to the tops of the outer walls on both sides of the tank. The tops of the two electric push rods are fixedly connected to the same second inlet hopper, which has four evenly distributed drain outlets in its center. The bottom of the first inlet hopper has an opening. Four rectangular support legs are welded to the outer wall of the tank bottom, and a water outlet pipe is located in the middle of the tank bottom. After rainwater collection, the device seals the bottom opening of the first inlet hopper through the outer wall of the second inlet hopper to prevent rainwater loss due to evaporation. However, in practical use, the following shortcomings exist: From a practical standpoint, the device only has one water outlet pipe, lacking diversion measures. In cases of heavy rainfall, the rainwater retention tank can quickly fill with a large amount of rainwater, potentially leading to overflow or overloading of the sponge system.

[0004] Therefore, there is a need for a real-time metering and display device for rainwater retention capacity in sponge facilities to solve the problem of overloading caused by the lack of diversion measures in existing technologies. Utility Model Content

[0005] The purpose of this invention is to provide a real-time metering and display device for rainwater retention capacity in sponge facilities, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a real-time metering and display device for rainwater retention capacity in sponge facilities, comprising a retention tank, a baffle frame fixedly connected to the inner wall of the retention tank near the top, a cover plate overlapping the top of the baffle frame, and multiple evenly distributed drainage holes penetrating the surface of the cover plate, a guide groove fixedly connected to the bottom of the baffle frame, an inlet pipe fixedly connected to the bottom of the guide groove, an inlet flow meter installed inside the inlet pipe, an ultrasonic water level sensor fixedly connected to the inner wall of one side of the retention tank, a display panel corresponding to the ultrasonic water level sensor installed on one side of the retention tank, a first drain pipe fixedly connected to the bottom of one side of the retention tank, a first drain flow meter installed inside the first drain pipe, and a diversion mechanism provided at the bottom of the retention tank.

[0007] It should be noted in the plan that the outer wall of the cover plate is in contact with the inner wall of the stagnation tank.

[0008] It is worth noting that filter screens are fixedly connected to the inner walls of each of the aforementioned leakage holes.

[0009] It should be further noted that a protective film is attached to the outer wall of the display panel.

[0010] In a preferred embodiment, the diversion mechanism includes a conical pipe fixedly connected to the bottom of the stagnation tank, a second drain pipe fixedly connected to the bottom of the conical pipe, connecting plates fixedly connected to the inner walls of both sides of the conical pipe, sliding rods slidably connected inside the two connecting plates, springs sleeved on the outer walls of the two sliding rods, sealing plates fixedly connected to the tops of the two sliding rods, and a second drain flow meter installed inside the second drain pipe.

[0011] In a preferred embodiment, the two springs are respectively fixedly connected between the top of the corresponding connecting plate and the bottom of the sealing plate.

[0012] In a preferred embodiment, the outer wall of the sealing plate is in contact with the top of the inner wall of the tapered tube.

[0013] Compared with the prior art, the real-time metering and display device for rainwater retention capacity of sponge facilities provided by this utility model has at least the following beneficial effects:

[0014] (1) By setting up a diversion mechanism, when the amount of rainwater increases, the rainwater pressure moves the sealing plate downward into the conical pipe, forming a gap between the conical pipe and the sealing plate. The rainwater is discharged from the gap and then discharged from the bottom of the second drainage pipe, thus realizing the diversion treatment of rainwater, improving the overall drainage capacity, reducing the risk of urban flooding, avoiding the retention of water or excessive water accumulation in the retention pond due to its inability to handle too much water, optimizing the efficiency of rainwater treatment, and making the process of rainwater retention and discharge smoother and more efficient.

[0015] (2) By setting up an inlet flow meter, an ultrasonic water level sensor, a first drainage flow meter and a second drainage flow meter to work together, the inlet flow meter monitors the flow of rainwater entering the retention tank in real time, the ultrasonic water level sensor accurately measures the water level in the tank, and the first drainage flow meter and the second drainage flow meter can monitor the drainage flow, forming a full-process data flow record to ensure the real-time and accuracy of the information. Through the display of real-time data, managers can obtain the current rainwater retention status through the display panel, and then adjust the retention and drainage strategies according to the actual situation to optimize the use and maintenance of the facilities.

[0021] The present invention will be further described below with reference to the embodiments.

[0022] Please see Figure 1-4 This utility model provides a real-time metering and display device for rainwater retention in sponge facilities, including a retention tank 1. A baffle 2 is fixedly connected to the inner wall of the retention tank 1 near the top. A cover plate 3 overlaps the top of the baffle 2. Multiple evenly distributed drainage holes 4 are opened through the surface of the cover plate 3. A guide groove 5 is fixedly connected to the bottom of the baffle 2. A water inlet pipe 6 is fixedly connected to the bottom of the guide groove 5. A water inlet flow meter 7 is installed inside the water inlet pipe 6. An ultrasonic water level sensor 8 is fixedly connected to the inner wall of one side of the retention tank 1. A display panel 9 corresponding to the ultrasonic water level sensor 8 is installed on one side of the retention tank 1. A first drainage pipe 10 is fixedly connected to the bottom of one side of the retention tank 1. A first drainage flow meter 11 is installed inside the first drainage pipe 10. A diversion mechanism 12 is provided at the bottom of the retention tank 1.

[0023] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the outer wall of the cover plate 3 fits snugly against the inner wall of the retention tank 1, which helps to enhance the sealing performance of the entire device and prevents external debris, garbage and other pollutants from entering the interior of the retention tank 1, thereby improving the reliability of the rainwater treatment system.

[0024] Further as Figure 1 and Figure 3 As shown, it is worth noting that the inner walls of multiple drainage holes 4 are all fixedly connected with filter screens. The filter screens can effectively prevent leaves, dust, garbage and other debris floating in the rainwater from entering the retention tank 1, avoiding clogging of the drainage holes 4 and other pipes, and ensuring the normal operation of the system. At the same time, by removing the interference of debris, the stability of the entire device is enhanced, and the system can operate without failure for a longer period of time, reducing potential failures caused by debris.

[0025] Further as Figure 2 As shown, it is worth noting that the outer wall of the display panel 9 is covered with a protective film. The protective film can effectively prevent the surface of the display panel 9 from being scratched, worn or otherwise physically damaged during equipment installation, transportation or daily use, and maintain the clarity and integrity of the display panel 9.

[0026] As can be seen from the above working process: by setting up the inlet flow meter 7, the ultrasonic water level sensor 8, the first drainage flow meter 11 and the second drainage flow meter 1207 to work together, and by displaying real-time data, the management personnel can obtain the current rainwater storage status through the display panel 9, and then adjust the storage and drainage strategies according to the actual situation to optimize the use and maintenance of the facilities. Among them, the inlet flow meter 7, the first drainage flow meter 11 and the second drainage flow meter 1207 are Endress+HauserProline 300 products, and the ultrasonic water level sensor 8 is a Siemens SITRANS Probe LU product.

[0027] Further as Figure 4As shown, it is worth noting that the diversion mechanism 12 includes a conical pipe 1201 fixedly connected to the bottom of the retention tank 1. A second drainage pipe 1202 is fixedly connected to the bottom of the conical pipe 1201. Connecting plates 1203 are fixedly connected to the inner walls on both sides of the conical pipe 1201. Sliding rods 1204 are slidably connected inside the two connecting plates 1203. Springs 1205 are sleeved on the outer walls of the two sliding rods 1204. Sealing plates 1206 are fixedly connected to the top of the two sliding rods 1204. A second drainage flow meter 1207 is installed inside the second drainage pipe 1202. By setting up the diversion mechanism 12, rainwater is diverted and treated, improving the overall drainage capacity, reducing the risk of urban flooding, preventing the retention tank 1 from being unable to handle too much water and causing excessive water retention or accumulation, optimizing the efficiency of rainwater treatment, and making the process of rainwater retention and discharge smoother and more efficient.

[0028] Further as Figure 4 As shown, it is worth noting that the two springs 1205 are respectively fixedly connected between the top of the corresponding connecting plate 1203 and the bottom of the sealing plate 1206. Under the action of the springs 1205, the sealing plate 1206 can move up and down flexibly. When the water flow is small, the sealing plate 1206 remains sealed. When the water flow is large, the pressure on the springs 1205 causes the sealing plate 1206 to drop and leak a gap.

[0029] Further as Figure 4 As shown, it is worth noting that the outer wall of the sealing plate 1206 fits into the top of the inner wall of the tapered tube 1201, which enables the device to achieve flexible drainage and improve the overall drainage capacity.

[0030] This solution has the following working process: In actual use, rainwater is collected from the drain hole 4. The filter screen on the inner wall of the drain hole 4 blocks solid pollutants in the rainwater. The filtered rainwater falls from the bottom of the inlet pipe 6 into the retention tank 1 through the guide channel 5. Then the rainwater is discharged from the first drain pipe 10. When the amount of rainwater increases, the rainwater pressure moves the sealing plate 1206 downward into the conical pipe 1201. A gap is formed between the conical pipe 1201 and the sealing plate 1206. The rainwater is discharged from the gap and then discharged from the bottom of the second drain pipe 1202, realizing the diversion treatment of rainwater. Throughout the process, the inlet flow meter 7 monitors the flow rate of rainwater entering the retention tank 1 in real time, the ultrasonic water level sensor 8 accurately measures the water level in the tank, and the first drainage flow meter 11 and the second drainage flow meter 1207 can monitor the drainage flow rate, forming a full-process data flow record.

[0031] In summary: By setting up the inlet flow meter 7, ultrasonic water level sensor 8, first drainage flow meter 11, and second drainage flow meter 1207 in coordination, and through the display of real-time data, managers can obtain the current rainwater retention status through the display panel 9, and then adjust the retention and drainage strategies according to the actual situation to optimize the use and maintenance of the facilities; by setting up the diversion mechanism 12, rainwater is diverted and treated, which improves the overall drainage capacity, reduces the risk of urban flooding, avoids the retention tank 1 from being unable to handle too much water and causing excessive water retention or accumulation, optimizes the efficiency of rainwater treatment, and makes the process of rainwater retention and discharge smoother and more efficient.
