Description

Technical Field

[0001] This invention discloses a field of wastewater monitoring technology, specifically relating to an urban wastewater monitoring device based on NB-IoT. In addition, this invention also relates to an urban wastewater monitoring and early warning method. Background Art

[0002] NB-IoT (Narrowband Internet of Things) is based on cellular networks and can be directly deployed on existing networks. Its main technological advantages are wide coverage and low power consumption. It is superior in terms of data security, network construction costs, industry chain, and network coverage.

[0003] Wastewater is becoming increasingly complex, generally including domestic sewage, industrial wastewater and runoff. It contains a large amount of organic matter, bacteria, viruses and other types and levels of toxic and harmful pollutants. Direct discharge into the environment will cause irreversible ecological pollution.

[0004] At some wastewater discharge outlets in the wild, staff need to conduct random water quality checks on-site at irregular intervals. This method is time-consuming, labor-intensive, and very inconvenient. Therefore, wastewater detection devices are usually installed at the discharge outlets. When the wastewater volume decreases, the detection devices are prone to becoming suspended in the air and cannot detect the wastewater. If the detection devices remain in the wastewater for a long time, pollutants or microorganisms can easily adhere to them, leading to a decrease in the accuracy of the test results. Summary of the Invention

[0005] The purpose of this invention is to provide an urban sewage monitoring device based on NB-IoT, which can solve the above-mentioned technical problems in practical use and has the advantage of being easy to use; in addition, this invention also discloses an urban sewage monitoring and early warning method, which can achieve the purpose of automatic early warning when sewage quality exceeds the standard.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0007] A city sewage monitoring device based on NB-IoT includes a support frame and a solar power generation component mounted on top of the support frame. A sewage detection mechanism is slidably mounted on the support frame. The sewage detection mechanism includes a connecting cylinder for sliding connection with the support frame, a floating body disposed inside the connecting cylinder, and an installation cylinder disposed inside the connecting cylinder via a connecting rod.

[0008] The mounting cylinder includes a barrel body and a top cover. The barrel body has a first mounting hole and a second mounting hole communicating with the first mounting hole. The barrel body is provided with several oblique holes communicating with the second mounting holes. A battery connected to a solar power generation component is installed in the first mounting hole. A controller, an NB-IoT module, and a detection module are connected together with the battery. The detection module is installed in the second mounting hole. Both the detection module and the NB-IoT module are connected to the controller. The NB-IoT module is used to connect to a monitoring cloud platform located in the cloud.

[0009] The lower end of the inner wall of the connecting cylinder is provided with a buoyancy adjustment component, which is connected to the controller and is used to adjust the overall buoyancy of the device.

[0010] Preferably, the buoyancy adjustment component includes an annular airbag, an inflation pump, and a deflation pump. The inflation pump and the deflation pump are disposed in the first mounting hole and connected to the battery and the controller. The inflation pump and the deflation pump are respectively connected to the controller through an inflation valve and a deflation valve. Both the inflation valve and the deflation valve are connected to the controller.

[0011] Further optimization involves installing a sensor inside the second mounting hole at the detection module location, and the sensor is connected to the controller.

[0012] The annular airbag is equipped with a hydrophobic coating.

[0013] Further specifying, the buoyant body is a ring-shaped foam or an airbag.

[0014] Further optimization involves a bracket that includes a mounting plate and several support columns located at the lower end of the mounting plate, with the support columns slidably connected to the connecting cylinder.

[0015] Preferably, the side wall of the connecting cylinder is provided with a lug corresponding to the support column, and the lug is provided with a guide hole, and the support column cooperates with the guide hole.

[0016] The detection module is a water quality analyzer.

[0017] The present invention discloses a method for monitoring and early warning of urban sewage, which includes using an NB-IoT-based urban sewage monitoring device to detect the quality of sewage;

[0018] The tested water quality information is sent to the monitoring cloud platform, which processes the water quality information and sends it to the user terminal and alarm terminal.

[0019] If the detected water quality information is within the standard water quality information range, it will be displayed on the user terminal and the data will be archived.

[0020] If the detected water quality information is outside the standard water quality range, the alarm terminal will sound an alarm and display it on the user terminal, while the data will be archived.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] This invention slides the wastewater detection mechanism onto a support frame, allowing it to float on the water surface under the action of an upper buoy. A buoyancy adjustment component regulates buoyancy. When wastewater quality testing is required, the overall buoyancy of the device decreases under the action of the buoyancy adjustment component. At this time, the connecting cylinder descends, bringing the lower end of the mounting cylinder into contact with and submerging the wastewater. The wastewater then enters the second mounting hole through an inclined hole. The detection module detects the wastewater and sends the water quality information to a monitoring cloud platform via a controller and an NB-IoT module. After testing, the overall buoyancy of the device increases under the action of the buoyancy adjustment component, causing the mounting cylinder to rise and its bottom to leave the water surface. Due to the inclined hole, the wastewater flows out along the inclined hole, separating the detection module from the wastewater. This prevents prolonged contact between the detection module and the wastewater, and prevents wastewater and plankton from adhering to the detection module, thus ensuring the accuracy of the test. Simultaneously, a solar power generation component at the top of the support frame converts solar energy into electrical energy for storage and powering the power-consuming components, facilitating long-term outdoor use of this invention.

[0036] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0037] Example 1

[0038] See Figures 2-4 This embodiment discloses an urban sewage monitoring device based on NB-IoT, including a support 101 and a solar power generation component 112 disposed on the top of the support 101. A sewage detection mechanism 102 is slidably disposed on the support 101. The sewage detection mechanism 102 includes a connecting cylinder 103 for sliding connection with the support 101, a floating body 104 disposed inside the connecting cylinder 103, and an installation cylinder 106 disposed inside the connecting cylinder 103 via a connecting rod 105.

[0039] The mounting cylinder 106 includes a barrel body 107 and a top cover 108. The barrel body 107 has a first mounting hole 109 and a second mounting hole 110 communicating with the first mounting hole 109. The barrel body 107 is provided with a plurality of oblique holes 111 communicating with the second mounting hole 110. A storage battery 113 connected to the solar power generation component 112 is disposed in the first mounting hole 109. A controller 114, an NB-IoT module 115, and a detection module 116 are connected together with the storage battery 113. The detection module 116 is installed in the second mounting hole 110. Both the detection module 116 and the NB-IoT module 115 are connected to the controller 114. The NB-IoT module 115 is used to connect to a monitoring cloud platform 117 located in the cloud.

[0040] The lower end of the inner wall of the connecting cylinder 103 is provided with a buoyancy adjustment component 118, which is connected to the controller 114 and is used to adjust the overall buoyancy of the device.

[0041] In this embodiment, the solar power generation component 112 is a solar power generation device in the prior art, and its specific structure and principle will not be described in detail here.

[0042] This invention slides the wastewater detection mechanism 102 onto the support 101, allowing it to float on the water surface under the action of the upper float 104. Buoyancy is adjusted via a buoyancy adjustment component 118. When wastewater quality testing is required, the overall buoyancy of the device decreases under the action of the buoyancy adjustment component 118. At this time, the connecting cylinder 103 descends, causing the lower end of the mounting cylinder 106 to contact and be submerged in the wastewater. The wastewater then enters the second mounting hole 110 through the inclined hole 111. The detection module 116 detects the wastewater and sends the water quality information to the monitoring cloud platform 117 via the controller 114 and the NB-IoT module 115. After testing, the overall buoyancy of the device increases under the action of the buoyancy adjustment component 118, causing the mounting cylinder 106 to move upwards, lifting its bottom off the water surface. Due to the inclined hole 111, the wastewater flows out, causing the detection module 116 to detach from the wastewater. It will not come into prolonged contact with sewage, and sewage and plankton will not adhere to the detection module 116, thus ensuring the accuracy of the detection; at the same time, the solar power generation component set on the top of the bracket 101 can convert solar energy into electrical energy for storage and power the power-consuming components, which facilitates the long-term outdoor use of this invention.

[0043] It should be noted that in actual use, the monitoring cloud platform 117 is used to connect to the user terminal 119, which can be a mobile phone, tablet or computer; in actual use, the controller 114 performs timed monitoring under its control, and staff can also control the controller 114 to issue monitoring commands through the user terminal 119, and then perform buoyancy adjustment and detection.

[0044] In this embodiment, the buoyancy adjustment component 118 includes an annular airbag 120, an inflation pump 121, and a deflation pump 122. The inflation pump 121 and the deflation pump 122 are disposed in the first mounting hole 109 and connected to the battery 113 and the controller 114. The inflation pump 121 and the deflation pump 122 are respectively connected to the controller 114 through an inflation valve and a deflation valve. Both the inflation valve and the deflation valve are connected to the controller 114.

[0045] In practical use, when buoyancy needs to be adjusted, the controller 114 controls the air pump 121 and the air pump 122, as well as the corresponding air inflator and air deflation valves. When the air pump 121 inflates the annular airbag 120, the annular airbag 120 is inflated, thereby increasing the overall buoyancy of the device. When the air pump 122 deflates the valve, the air inside the annular airbag 120 is expelled, and the annular airbag 120 is deflated. At this time, the overall buoyancy of the device will decrease, and the main buoyancy of the device will be provided by the upper float 104. At this time, the lower end of the mounting cylinder 106 will be submerged in the sewage, which is convenient for the detection module 116 to detect the sewage quality.

[0046] Further optimization involves installing a sensor inside the second mounting hole at the detection module 116, which is connected to the controller 114.

[0047] The controller uses sensors to detect whether wastewater has entered the second mounting hole 110. Once the wastewater enters the second mounting hole 110, the controller can activate the detection module 116 to detect the wastewater.

[0048] The annular airbag 120 is equipped with a hydrophobic coating to reduce the adhesion of dirt and plankton.

[0049] The floating body 104 is a ring-shaped foam or airbag.

[0050] Further optimization involves the bracket 101 including a mounting plate 124 and several support columns 123 disposed at the lower end of the mounting plate 124, the support columns 123 being slidably connected to the connecting cylinder 103. Each support column 123 has a pointed tip at its bottom for easy insertion into the soil at the drainage outlet.

[0051] The connecting cylinder 103 has a support lug 125 on its side wall that corresponds to the support column 123. The support lug 125 has a guide hole 126, and the support column 123 cooperates with the guide hole 126.

[0052] Among them, the detection module 116 is a water quality tester.

[0053] Example 2

[0054] See Figure 1 This embodiment discloses a method for monitoring and early warning of urban sewage, including using the NB-IoT-based urban sewage monitoring device described in Embodiment 1 to detect the quality of sewage;

[0055] The tested water quality information is sent to the monitoring cloud platform 117. The monitoring cloud platform 117 is used to process the water quality information and send it to the user terminal 119 and the alarm terminal 127.

[0056] If the detected water quality information is within the standard water quality information range, it will be displayed at user terminal 119 and the data will be archived;

[0057] Among them, water quality information refers to the specific water quality conditions, such as color value, heavy metal content value, oxygen content value, nitrogen content value, and other water quality evaluation values;

[0058] If the detected water quality information is outside the standard water quality information range, the alarm terminal 127 will sound an alarm and display it on the user terminal 119, while the data will be archived.

[0059] In this way, the urban sewage monitoring device based on NB-IoT will periodically upload the detected sewage information to the monitoring cloud platform 117. After the monitoring cloud platform 117 processes the sewage information, it can issue a timely warning if the water quality exceeds the standard.

[0060] In practical use, the NB-IoT-based urban sewage monitoring device also includes a GPS positioning module. Based on the location of the drainage outlet, an NB-IoT-based urban sewage monitoring device is installed at each outlet. In actual use, the location of the drainage outlet is marked and mapped on an electronic map. After detecting the sewage quality, the NB-IoT-based urban sewage monitoring device transmits the corresponding GPS signal to the monitoring cloud platform 117. The monitoring cloud platform 117 integrates the water quality information and GPS signal and displays it on the electronic map. Thus, when the alarm terminal issues a warning signal, staff can quickly locate the drainage outlet and assess the sewage quality at that outlet.

[0061] Although the preferred embodiments of the present invention have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0062] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. It should be noted that any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
