DETAILED DESCRIPTION

[0027] The following is a further detailed description of the embodiments of the invention in conjunction with the accompanying drawings to make the objectives, technical solutions and technical effects of the invention more clearly presented.

[0028] like Figure 1-5 As shown, the present invention discloses an automatic water quality monitoring system with an intelligent operation and maintenance mode, including a water sample acquisition unit 100, a water quality detection unit 200, a cleaning unit 400 and an operation and maintenance control unit 300. The operation and maintenance control unit 300 controls the cleaning unit 400 to clean the water sample acquisition unit 100 and the water quality detection unit 200. Among them, the water sample acquisition unit 100 includes a water pump 101 and a water sample tank 102, and the water sample tank 102 is used to hold the sewage sample sucked by the water pump 101; a drain port is provided at the bottom of the water sample tank 102. The water quality detection unit 200 is connected to the water sample tank 102 through a pipeline main pipe 201, and sewage outlets are provided at the bottom of both ends of the pipeline main pipe 201.

[0029] Here, the cleaning unit 400 includes a first cleaning component and a second cleaning component. The first cleaning component includes a first magnetic roller brush 401, a first magnetic field generator 402, and a first guide device 403. The first magnetic roller brush 401 has wash bristles and the size of the first magnetic roller brush 401 corresponds to the size of the inner cavity of the water sample tank 102. The first magnetic field generator 402 is arranged outside the water sample tank 102 and can fit, and moves up and down along the water sample tank 102 through the first guide device 403. The first magnetic field generator 402 changes the magnetic field to make the first magnetic roller brush 401 rotate and follow the first magnetic field generator 402 to move up and down. The second cleaning component includes a second magnetic roller brush 404, a second magnetic field generator, and a second guide device. The second magnetic roller brush 404 has wash bristles and the size of the second magnetic roller brush 404 corresponds to the size of the inner tube of the pipeline main 201. The second magnetic field generator is arranged outside the pipeline main 201 and can fit, and moves forward and backward along the pipeline main 201 through the second guide device. A cleaning fence 405 is provided at the bottom of the water sample tank 102. The cleaning fence 405 is used to correspond to the bristles of the roller brush. The first magnetic roller brush 401 rotates close to the cleaning fence 405. The cleaning fence 405 contacts the bristles of the roller brush to form a cleaning process. This can clean up the debris attached to the first magnetic roller brush 401 to avoid affecting the cleaning process. Here, the first magnetic roller brush 401 includes a magnetic core 407, a hard shell layer 408, a soft shell layer 409 and bristles 410. Figure 6 As shown, the first magnetic roller brush 401 and the second magnetic roller brush 404 have the same structure.

[0030] Here, the first guide device 403 is an electric lifting device, and the second guide device is a track traction device, and the track traction device and the pipeline main pipe 201. This can improve the automation and accuracy of the cleaning process, prevent the roller brush from deviating from the cleaning area, ensure that all key parts of the system can be effectively cleaned, reduce the need for manual intervention, and improve operation and maintenance efficiency.

[0031] According to the above structure, the operation and maintenance control unit 300 obtains the dirt condition of the inner wall of the water sample tank 102 and the pipeline main pipe 201 through the sensor, and controls the cleaning unit 400 to clean the water sample acquisition unit 100 and the water quality detection unit 200, specifically controlling the first cleaning component or the second cleaning component to perform the cleaning operation.

[0032] Here, the operation and maintenance control unit 300 automatically adjusts the roller brush speed and cleaning strategy according to the type and thickness of dirt monitored by the ultrasonic sensor 301. This setting can accurately adapt to various dirt conditions, avoid excessive cleaning or insufficient cleaning, extend the service life of the system, improve the operation and maintenance efficiency, reduce labor costs, and allow water quality monitoring to be carried out continuously, stably and efficiently. The cleaning strategy includes the cleaning duration, the number of cycles, the number of revolutions of the first magnetic roller brush 401 and the second magnetic roller brush 404, and the moving speed. Ultrasonic waves can penetrate the walls of the water sample tank 102 and the pipeline main pipe 201. When encountering dirt, reflected waves will be generated. The sensor receives and analyzes the characteristics of these reflected waves, such as wave intensity, frequency changes, etc., and then determines the type of dirt. Dirt of different composition and density reflects ultrasonic waves differently, and the reflected wave information is converted into corresponding dirt type data, such as algae dirt, silt dirt, chemical precipitation dirt, etc. In terms of measuring dirt thickness, the time difference from ultrasonic emission to reception is directly related to the dirt thickness. As dirt gradually accumulates and thickens, the ultrasonic propagation path becomes longer, and the time difference increases accordingly. The ultrasonic sensor 301 can accurately calculate the thickness of the dirt based on precise time measurement and pre-calibrated parameters. The operation and maintenance control unit 300 can collect dirt type data in advance, that is, pre-store multiple cleaning modes to deal with different types of dirt. The operation and maintenance control unit 300 obtains the ultrasonic sensor 301 data and classifies the ultrasonic sensor 301 data to correspond to different cleaning modes.

[0033] like Figure 2 As shown, a switch valve is provided between the water sample tank 102 and the water pump 101, a switch valve is provided between the pipeline main pipe 201 and the universal reaction tank 202, and switch valves are provided at the sewage outlets at both ends of the pipeline main pipe 201. The switch valves are electromagnetic switch valves. It should be clear that when cleaning, it is necessary to inject clean water first, or pump in sample water, and then close the switch valve to form a closed cleaning space to avoid affecting other components. This should be clear to technical personnel in this field.

[0034] Here, the connection between the pipeline main pipe 201 and the water sample tank 102 is a long cylindrical cavity structure, which is close to the cleaning fence 405 and has a cleaning window 406, so that the cleaning fence 405 can partially extend into the long cylindrical cavity structure; the cleaning fence 405 is in a long strip shape, and the cleaning fence has long protrusions evenly distributed along its outer circumference. It should be noted that the cleaning fence 405 is made of antibacterial material, and the long protrusions are mainly used to clean the bristles 410 on the first magnetic roller brush 401 and the second magnetic roller brush 404, and the antibacterial material prevents bacteria from growing and affecting the results.

[0035] like Figure 4As shown, in order to assist in solving the problem of cleaning the first magnetic roller brush 401, the second magnetic roller brush 404 and the cleaning fence 405 themselves, an ultrasonic cleaning device 410 is provided at the bottom of the water sample tank 102. The ultrasonic cleaning device 410 can clean the first magnetic roller brush 401, the second magnetic roller brush 404 and the cleaning fence 405 at the same time, ensuring the pollution problem of the cleaning tools themselves, and avoiding the cleaning tools from affecting the monitoring data results.

[0036] Here, water quality sensors are installed in the water quality detection unit 200, and the water quality sensors include a temperature sensor, a pH sensor, a dissolved oxygen sensor, a conductivity sensor, an ammonia nitrogen sensor, a total phosphorus sensor, and a total nitrogen sensor; the temperature sensor, the pH sensor, the dissolved oxygen sensor, and the conductivity sensor are respectively installed on the pipeline main pipe 201; the ammonia nitrogen sensor, the total phosphorus sensor, and the total nitrogen sensor are respectively connected to the pipeline main pipe 201 through a universal reaction tank 202.

[0037] Based on the above solution, a third cleaning component is further provided in the reaction tank 202 for cleaning the reaction tank 202 and the sensor. The third cleaning component has the same structure as the first cleaning component, and also uses an external magnetic field generator to drive the magnetic roller brush inside the reaction tank 202 for cleaning.

[0038] The operation and maintenance control unit 300 in the above scheme obtains the dirt conditions on the inner wall of the water sample tank 102 and the pipeline main pipe 201 through the ultrasonic sensor 301. In the first cleaning component of the cleaning unit 400, the first magnetic field generator 402 is arranged outside the water sample tank 102 and can fit, and moves up and down along the water sample tank 102 through the first guiding device 403. The changing magnetic field generated by it makes the first magnetic roller brush 401 with brush hairs and adapted to the size of the inner cavity of the water sample tank 102 rotate and follow the up and down movement, thereby cleaning the water sample tank 102. In the second cleaning component, the second magnetic field generator is outside the pipeline main pipe 201 and can fit, and moves back and forth along the pipeline main pipe 201 through the track traction device, so that the second magnetic roller brush 404 with brush hairs adapted to the size of the inner pipe of the pipeline main pipe 201 cleans the pipeline main pipe 201. The operation and maintenance control unit 300 automatically adjusts parameters such as the roller brush speed according to the type and thickness of the dirt.

[0039] According to the above structure, the operation process includes: after starting, the sensor continuously monitors the dirt on the inner wall of the water sample tank 102 and the pipeline main pipe 201, and transmits the sensor data to the operation and maintenance control unit 300 in real time. The operation and maintenance control unit 300 analyzes the sensor data and determines whether cleaning is required, and issues instructions to the cleaning unit 400 according to the type and thickness information of the dirt. During cleaning, the first magnetic field generator 402 corresponding to the first magnetic roller brush 401 is started, adheres to the outer wall of the water sample tank 102 and drives it to move up and down along the tank wall through the first guide device 403, and the changing magnetic field causes the first magnetic roller brush 401 to rotate and wash. The corresponding operation of the second magnetic roller brush 404 is similar, and it cleans along the pipeline main pipe 201 front and back under the action of the second magnetic field generator and the track traction device. After cleaning, the bottom sewage outlets at both ends of the pipeline main pipe 201 are opened to discharge sewage, and the third cleaning component in the reaction tank 202 cleans the reaction tank 202 and the sensor as needed, and the system returns to the normal monitoring state.

[0040] At the water quality monitoring station of the urban drinking water source, a large amount of raw water samples are extracted into the water sample tank by the water sample acquisition unit every day, and the water quality detection unit detects in real time; due to the complex composition of the water body in the water source, dirt is easy to accumulate. For example, in the spring and summer, the peak season for algae reproduction, the sensor detects that the algae dirt in the pipeline main 201 increases and the thickness increases. The operation and maintenance control unit quickly instructs the cleaning unit to adjust the roller brush speed to speed up, the first and second magnetic roller brushes clean efficiently, and the sewage outlet discharges sewage in time. At the same time, the third cleaning component in the reaction tank ensures the normal operation of sensors such as ammonia nitrogen and total phosphorus.
