Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an environmental monitoring device for wastewater treatment based on the Internet of Things. Background Technology

[0002] Wastewater treatment refers to the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. In traditional wastewater treatment industries, monitoring nodes have always been scattered, leading to difficulties in water quality monitoring, management challenges, and high costs in terms of manpower and resources. To improve production efficiency and reduce engineering costs, achieving remote monitoring and minimal or even unmanned monitoring is of great significance. Furthermore, most existing monitoring methods can only sample water quality data from the wastewater surface. For wastewater treatment, water quality data can vary significantly at different depths, resulting in false alarms or unreliable monitoring results. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an IoT-based environmental monitoring device for wastewater treatment. This device can remotely monitor the site and transmit data remotely via the IoT, thereby improving the convenience of monitoring. It can also collect water quality data from wastewater at different depths to improve the reliability of monitoring results.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A wastewater treatment environmental monitoring device based on the Internet of Things (IoT) is characterized by the following: it includes monitoring terminals located at various monitoring points, as well as IoT gateways, monitoring servers, and cloud servers. Each monitoring terminal communicates with the monitoring server through the IoT gateway, and the monitoring server communicates with the cloud server through the Internet.

[0006] The monitoring terminal includes a housing, a mounting base inside the housing, and a detection water tank. A winding mechanism and a water pump are fixed on the mounting base. A water inlet pipe is wound within the winding mechanism. A guide mechanism is fixed on the outer wall of the housing. One end of the water inlet pipe is connected to a counterweight mechanism after being folded by the guide mechanism. A water inlet hole is provided on the counterweight mechanism. The other end of the water inlet pipe is connected to the water inlet of the water pump through a water inlet pipe. The water outlet of the water pump is connected to the water inlet of the detection water tank through a water supply pipe. A data acquisition module for collecting water quality data in sewage is provided inside the detection water tank. A drain pipe connected to the detection water tank is connected to the bottom of the housing. An electrically controlled valve is installed on the drain pipe.

[0007] Furthermore, a sealed cavity is provided inside the tank above the detection water tank, and a control mechanism is installed in the sealed cavity. The output end of the acquisition module is connected to the input end of the control mechanism, and the control ends of the winding mechanism, water pump, and electrically controlled valve are connected to the output end of the control mechanism.

[0008] Furthermore, a level gauge is installed at the top inside the detection tank, and the output end of the level gauge is connected to the input end of the control mechanism.

[0009] Furthermore, the control mechanism includes a control module and a power module. The input terminal group of the control module is connected to the acquisition module and the level gauge. The output terminal group of the control module is connected to a first drive module, a second drive module, and a third drive module. The output terminal of the first drive module is connected to the control terminal of the winding mechanism, the output terminal of the second drive module is connected to the control terminal of the water pump, and the output terminal of the third drive module is connected to the control terminal of the electrically controlled valve. The control module is also connected to a communication module for information interaction with the Internet of Things gateway.

[0010] Furthermore, a positioning module is also connected to the control module.

[0011] Furthermore, the guiding mechanism includes a mounting bracket, one end of which is fixedly connected to the outer wall of the housing, and the other end of which is rotatably provided with a guide roller having a guide groove, and the water inlet pipe is confined within the guide groove of the guide roller.

[0012] Furthermore, an encoder is installed inside the guide roller. The sensing end of the encoder is located inside the guide groove and in contact with the water inlet pipe. The output end of the encoder is connected to the input end of the control mechanism.

[0013] Furthermore, the counterweight mechanism is teardrop-shaped, and its small end is detachably connected to the water inlet end of the water pipe. The counterweight mechanism is evenly distributed with water inlet holes that communicate with the water pipe.

[0014] Furthermore, a display terminal and an alarm terminal are also connected to the monitoring server.

[0019] Figure 2 This is a structural diagram of the monitoring terminal;

[0020] Figure 3 This is a block diagram of the monitoring terminal. Detailed Implementation

[0021] The specific embodiments and working principle of this utility model will be further described in detail below with reference to the accompanying drawings.

[0022] like Figure 1 As shown, an IoT-based wastewater treatment environmental monitoring device includes monitoring terminals located at various monitoring points, as well as IoT gateways, a monitoring server, and a cloud server. Each monitoring terminal communicates with the monitoring server via an IoT gateway, and the monitoring server communicates with the cloud server via the Internet. A display terminal and an alarm terminal are also connected to the monitoring server. Specifically, the monitoring terminals are used to sample wastewater at different depths at each monitoring point and collect water quality data, which is then uploaded to the monitoring server via the IoT gateway. The IoT gateway enables data interaction between the monitoring terminals and the monitoring server. The monitoring server analyzes and processes the water quality data and generates alarm commands according to preset rules. The display terminals display the water quality data collected by each monitoring terminal. The alarm terminals issue alarm signals based on alarm commands. The cloud server backs up the monitoring records of this device to prevent data loss and facilitate data analysis.

[0023] Based on the above, it can be seen that this device uses Internet of Things (IoT) technology to network the monitoring terminals located at various monitoring points, thereby enabling remote monitoring of the sewage treatment site and remote data transmission. This improves the convenience of monitoring and overcomes the problems of difficult water quality monitoring, high management difficulty, and high consumption of manpower and resources in existing technologies.

[0024] See appendix Figure 2The monitoring terminal includes a housing 1, with multiple support legs 2 at the bottom of the housing 1. A mounting base 3 and a detection water tank 4 are located inside the housing 1. A winding mechanism 5 and a water pump 6 are mounted and fixed on the mounting base 3. A water inlet pipe 7 is wound within the winding mechanism 5. A guide mechanism 8 is fixed on the outer wall of the housing 1. One end of the water inlet pipe 7 is connected to a counterweight mechanism 9 after being folded by the guide mechanism 8. A water inlet hole 10 is provided on the counterweight mechanism 9. The other end of the water inlet pipe 7 is connected to the water inlet of the water pump 6 via a water inlet pipe 11. The water outlet of the water pump 6 is connected to a water supply pipe. 12 is connected to the inlet of the detection water tank 4. The detection water tank 4 is equipped with a data acquisition module 13 for collecting water quality data in sewage. A drain pipe 14 connected to the detection water tank 4 is connected to the bottom of the tank body 1. An electrically controlled valve 15 is installed on the drain pipe 14. A sealed cavity 16 is provided in the tank body 1 above the detection water tank 4. A control mechanism 17 is installed in the sealed cavity 16. The output end of the data acquisition module 13 is connected to the input end of the control mechanism 17. The control ends of the winding mechanism 5, the water pump 6 and the electrically controlled valve 15 are connected to the output end of the control mechanism 17.

[0025] During wastewater quality data collection, the control mechanism 17 first issues a control command to close the electrically controlled valve 15. Simultaneously, the control mechanism 17 issues a control command to rotate the winding mechanism 5. Under the gravity of the counterweight mechanism 9, the water inlet pipe 7 sinks into the wastewater until it reaches the required depth. Then, the water pump 6 is activated to sample the wastewater, pumping it into the testing tank 4 via the water inlet pipe 7, inlet pipe 11, and supply pipe 12. The acquisition module 13, located in the testing tank 4, detects the sampled wastewater for COD, total nitrogen, total phosphorus, and other water quality data. The control module then transmits the detected water quality data to the monitoring server via an IoT gateway. If testing at other depths is required, a control command is issued to open the electrically controlled valve 15, discharging the wastewater from the testing tank 4. This testing process is then repeated. Once all depths of wastewater testing are completed, the control mechanism 17 issues a control command to rotate the winding mechanism 5, winding the water inlet pipe 7 into the winding mechanism 5. Simultaneously, a control command is issued to open the electrically controlled valve 15, discharging the wastewater from the testing tank 4.

[0026] Therefore, this device, through the cooperation of the winding mechanism 5 and the counterweight mechanism 9, can adjust the sampling position of the water inlet pipe 7 as needed, thereby enabling the collection of water quality data from sewage at different depths and effectively improving the reliability of the monitoring results. In specific implementation, the winding mechanism 5 can be an electric hose reel (also known as a water drum) used in car washes.

[0027] from Figure 2It can also be seen that a level gauge 18 is installed at the top of the inner side of the detection tank 4, and the output end of the level gauge 18 is connected to the input end of the control mechanism 17.

[0028] By setting up the level gauge 18, the liquid level in the detection tank 4 can be detected in real time, which makes it easier for the control mechanism 17 to control the working status of the water pump 6 and the electric control valve 15 according to the liquid level in the detection tank 4. This enables the automated management and control of the wastewater quality data collection process, further solving the problems of difficult water quality monitoring and high manpower and material resources in the existing technology.

[0029] like Figure 2 As shown, the guiding mechanism 8 includes a mounting bracket 81, one end of which is fixedly connected to the outer wall of the housing 1, and the other end of the mounting bracket 81 is rotatably provided with a guide roller 82 having a guide groove, and the water pipe 7 is confined within the guide groove of the guide roller 82.

[0030] The guide mechanism 8 facilitates the guidance of the water pipe 7 by the counterweight mechanism 9, thereby helping to sample sewage at different depths.

[0031] Furthermore, an encoder 83 is installed inside the guide roller 82. The sensing end of the encoder 83 is located inside the guide groove and in contact with the water pipe 7. The output end of the encoder 83 is connected to the input end of the control mechanism 17.

[0032] By setting the encoder 83, the length of the water inlet pipe 7 passing through the encoder 83 can be detected, thereby calculating the depth of sewage at the inlet end of the water inlet pipe 7. Therefore, based on the signal of the encoder 83, the control mechanism 17 can control the state of the winding mechanism 5, thereby automating the sewage sampling process and further solving the problems of difficult water quality monitoring and high manpower and material resources in the existing technology.

[0033] from Figure 2 It can also be seen that the counterweight mechanism 9 is teardrop-shaped, and the small end of the counterweight mechanism 9 is detachably connected to the water inlet end of the water pipe 7. The counterweight mechanism 9 is evenly distributed with water inlet holes 10 that are connected to the water pipe 7.

[0034] The aforementioned counterweight mechanism 9 not only drives the water inlet pipe 7 to sink into the sewage, but also achieves a filter effect through the evenly distributed water inlet holes 10, thereby preventing impurities in the sewage from clogging the water inlet pipe 7 and other pipes. In specific implementation, the counterweight mechanism 9 is made of corrosion-resistant metal material to ensure the effectiveness of driving the water inlet pipe 7 to sink in the sewage.

[0035] See appendix Figure 3The control mechanism 17 includes a control module and a power module. The input terminals of the control module are connected to the acquisition module 13 and the level gauge 18. The output terminals of the control module are connected to a first drive module, a second drive module, and a third drive module. The output terminal of the first drive module is connected to the control terminal of the winding mechanism 5, the output terminal of the second drive module is connected to the control terminal of the water pump 6, and the output terminal of the third drive module is connected to the control terminal of the electrically controlled valve 15. The control module is also connected to a communication module for information interaction with the Internet of Things gateway and a positioning module. The power module provides power to all the above modules. Specifically, the acquisition module 13 is used to detect the water quality data of the wastewater in the detection tank 4, the level gauge 18 is used to detect the level of the wastewater in the detection tank 4, the positioning module is used to acquire the location data of the monitoring terminal, the control module is used to receive signals from the acquisition module 13, the level gauge 18, and the positioning module, and the control module is also used to control the status of the winding mechanism 5, the water pump 6, and the electrically controlled valve 15 as needed. The communication module is used to receive signals from the monitoring server or to upload water quality data collected by the monitoring terminal and location signals collected by the positioning module to the monitoring server.

[0036] Based on the above structure, the principle of this device can be understood as follows:

[0037] During wastewater quality data collection, the control mechanism 17 first issues a control command to close the electrically controlled valve 15. Simultaneously, the control mechanism 17 issues a control command to rotate the winding mechanism 5. Under the gravity of the counterweight mechanism 9, the water inlet pipe 7 sinks into the wastewater until it reaches the required depth. Then, the water pump 6 is activated to sample the wastewater, pumping it into the testing tank 4 via the water inlet pipe 7, inlet pipe 11, and supply pipe 12. The acquisition module 13, located in the testing tank 4, detects the sampled wastewater for COD, total nitrogen, total phosphorus, and other water quality data. The control module then transmits the detected water quality data to the monitoring server via an IoT gateway. If testing at other depths is required, a control command is issued to open the electrically controlled valve 15, discharging the wastewater from the testing tank 4. This testing process is then repeated. Once all depths of wastewater testing are completed, the control mechanism 17 issues a control command to rotate the winding mechanism 5, winding the water inlet pipe 7 into the winding mechanism 5. Simultaneously, a control command is issued to open the electrically controlled valve 15, discharging the wastewater from the testing tank 4.

[0038] Subsequently, the control module receives water quality data collected by the acquisition module 13 and location signals collected by the positioning module, and uploads them to the monitoring server via the IoT gateway through the communication module. The monitoring server analyzes and processes the water quality data to obtain water quality monitoring data from each monitoring terminal, and generates alarm commands according to preset rules. The monitoring server sends the water quality monitoring data to the display terminal for display, sends the alarm command to the alarm terminal to issue an alarm signal, and simultaneously backs up the data to the cloud server.

[0039] In summary, this device not only utilizes IoT technology to network monitoring terminals located at various monitoring points, enabling remote monitoring of the wastewater treatment site and remote data transmission, thereby improving the convenience of monitoring and overcoming the problems of difficult water quality monitoring, high management difficulty, and high manpower and material consumption in existing technologies; but also, through the cooperation of the winding mechanism and the counterweight mechanism, the sampling position of the water inlet pipe can be adjusted as needed, thereby enabling water quality data collection from wastewater at different depths and effectively improving the reliability of monitoring results.
