Description

Technical Field

[0001] This utility model relates to the field of wastewater discharge monitoring technology, and in particular to an online monitoring device for water pollution sources. Background Technology

[0002] Water is the material basis for human survival and is a non-renewable energy source. With rapid industrial development, water pollution has become increasingly serious, severely threatening human survival and making water pollution control an urgent priority. Some enterprises, due to large volumes of wastewater discharge and high wastewater treatment costs, resort to illegal discharge of wastewater to reduce costs. This phenomenon persists despite repeated prohibitions. To prevent such illegal discharges, environmental protection departments typically need to dispatch personnel to conduct on-site inspections of various discharge points.

[0003] However, the method of conducting on-site inspections of each sewage outlet makes it difficult to achieve 24 / 7 monitoring of each outlet, resulting in poor regulatory effectiveness. Furthermore, when sewage discharge exceeds standards, staff often fail to detect and immediately close the outlets, causing some wastewater to be discharged into the environment without treatment. This delay not only affects the effectiveness of pollution control but also poses a continuous risk to the environment. Utility Model Content

[0004] The purpose of this utility model is to provide an online monitoring and drainage device for water pollution sources in order to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0027] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0028] 1. In this utility model, fiber optic sensor modules are installed at the sewage outlets of each sewage pipe 1 to detect the sewage discharge status of each sewage outlet. The detected sewage discharge data is sent to the cloud information server for processing, and the processed sewage discharge data is sent to the monitoring terminal for display.

[0029] 2. In this utility model, when the fiber optic sensor module detects that the sewage outlet is discharging sewage outside the designated sewage discharge period, it transmits the sewage discharge signal to the main control board. The main control board then controls the opening of the first and third control valves. The sewage flows into the sampler through the second horizontal end of the T-shaped pipe, facilitating subsequent water quality testing of the illegally discharged sewage. When the liquid level sensor reaches the set value (i.e., the sampling amount is sufficient), the liquid level sensor transmits the signal to the main control board.

Simultaneously, the sewage flows out through the first horizontal end of the T-shaped pipe and is collected by the sewage return pool, preventing the problem of excessive sewage volume caused by illegal discharge by enterprises.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figure 1-3This utility model provides a technical solution: an online monitoring and drainage device for water pollution sources, including a monitoring terminal, a cloud information server, a communication unit, and an optical fiber sensor module. The optical fiber sensor module includes an optical fiber strain sensor and a dot-shaped grating temperature sensor. The optical fiber sensor module is installed at the discharge outlets of different sewage pipes 1. When sewage is discharged from the discharge outlet, the splashed water will cause a change in strain force on the surface of the optical fiber strain sensor, and may also cause a change in temperature. By detecting the stress and temperature changes through the optical fiber strain sensor and the dot-shaped grating temperature sensor, it can be determined whether sewage is being discharged from the discharge outlet. They are redundant and have higher accuracy. The communication unit includes one or more of the following: optical fiber communication module, Beidou satellite communication module, GPRS communication module, NB-IoT communication module, and 5G / 4G communication module. The optical fiber strain sensor and the dot-shaped grating temperature sensor are respectively connected to the cloud information server through the communication unit. The cloud information server is connected to the monitoring terminal. Fiber optic sensor modules are installed at the discharge outlets of each sewage pipe 1 to detect the sewage discharge status of each outlet. The detected sewage discharge data is sent to the cloud information server for processing, and the processed sewage discharge data is sent to the monitoring terminal for display. The monitoring terminal determines whether each sewage outlet is discharging sewage based on the received sewage discharge data. It can automatically monitor each sewage outlet 24 hours a day and detect sewage discharge in a timely manner without manual inspection. It is highly efficient, has good monitoring effect, and saves a lot of manpower and material resources.

[0037] Specifically, such as Figure 1 and Figure 2 As shown, the alarm unit includes an audible and visual alarm unit and an SMS alarm unit. The audible and visual alarm unit and the SMS alarm unit are respectively connected to the monitoring terminal and are used to issue an alarm when an alarm command is received from the monitoring terminal. The audible and visual alarm unit is used to issue an audible and visual alarm when an alarm command is received from the monitoring terminal, and the SMS alarm unit is used to send an alarm message to the user's mobile phone when an alarm command is received from the monitoring terminal, so that remote users can promptly detect abnormal sewage discharge.

[0038] Specifically, such as Figure 1-3As shown, the vertical end of the T-shaped pipe 2 is fixedly connected to the sewage pipe 1 near the sewage outlet. The sewage return tank 4 is connected to the first horizontal end of the T-shaped pipe 2. The sampler 5 is connected to the second horizontal end of the T-shaped pipe 2. The liquid level sensor is installed on the top side of the sampler 5. The main control board and the liquid level sensor are connected through a communication unit. The first control valve 31 is installed on the vertical end of the T-shaped pipe 2. The second control valve 32 is installed on the first horizontal end of the T-shaped pipe 2. The third control valve 33 is installed on the second horizontal end of the T-shaped pipe 2. The three sets of control valves are electrically connected to the main control board. When the fiber optic sensor module detects that the sewage outlet is discharging sewage outside the designated discharge period, it transmits the discharge signal to the main control board. The main control board then controls the opening of the first control valve 31 and the third control valve 33. The sewage flows into the sampler 5 through the second horizontal end of the T-shaped pipe 2, facilitating subsequent water quality testing of the illegally discharged sewage. When the liquid level sensor reaches the set value (i.e., the sampling volume is sufficient), the liquid level sensor transmits the signal to the main control board. The main control board then controls the opening of the second control valve 32 and the closing of the third control valve 33 to stop the sampling process. Simultaneously, the sewage flows out through the first horizontal end of the T-shaped pipe 2 and is collected by the sewage return pool 4, preventing the sewage volume from exceeding the standard due to illegal discharge by the enterprise.

[0039] This device can not only monitor sewage discharge in real time, but also take automatic measures when abnormal sewage discharge is detected, such as opening or closing the corresponding control valves and taking sewage samples. This greatly improves the timeliness and effectiveness of supervision, reduces reliance on manual inspection, lowers operating costs, and enhances monitoring results.

[0040] Specifically, such as Figure 1 and Figure 2 As shown, the photovoltaic power generation device is electrically connected to the fiber optic strain sensor, the dot grating temperature sensor, the liquid level sensor, the communication unit, the main control board, and three sets of control valves, respectively, to supply them with power.

[0041] Working principle: In use, firstly, fiber optic sensor modules are set at the sewage outlets of each sewage pipe 1 to detect the sewage discharge status of each sewage outlet, and send the detected sewage discharge data to the cloud information server for processing. The processed sewage discharge data is then sent to the monitoring terminal for display. The monitoring terminal determines whether each sewage outlet is discharging sewage based on the received sewage discharge data. It can automatically monitor each sewage outlet 24 hours a day and detect sewage discharge in a timely manner without manual inspection. It is highly efficient, has good monitoring effect, and saves a lot of manpower and material resources.

[0042] Secondly, when the fiber optic sensor module detects that the sewage outlet is discharging sewage outside the designated sewage discharge period, it transmits the sewage discharge signal to the main control board. The main control board then controls the opening of the first control valve 31 and the third control valve 33. The sewage flows into the sampler 5 through the second horizontal end of the T-shaped pipe 2, facilitating subsequent water quality testing of the illegally discharged sewage. When the liquid level sensor reaches the set value (i.e., the sampling amount is sufficient), the liquid level sensor transmits the signal to the main control board. The main control board then controls the opening of the second control valve 32 and the closing of the third control valve 33 to stop the sampling process. At the same time, the sewage flows out through the first horizontal end of the T-shaped pipe 2 and is collected by the sewage return pool 4, preventing the sewage volume from exceeding the standard due to illegal discharge by enterprises.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
