Description

Technical Field

[0001] This invention patent belongs to the field of water environment management test and measurement equipment, and relates to a rural river water environment management simulation device and method. Background Art

[0002] Rural rivers are essential for the drainage of rural residents' daily lives and production, playing a vital role in flood control, drainage, and water purification. However, with the rapid economic and social development of my country's rural areas and the significant loss of rural labor, the pollution load on rural rivers has continued to increase, and the lack of effective supervision has led to siltation in riverbeds, deterioration of the water environment, and degradation of aquatic ecosystems. This has led to seasonal and perennial black and odorous water bodies, directly impacting the daily lives and production of rural residents and severely restricting the sustainable development of the rural economy and society.

[0003] Riverbed sediment contains a large number of endogenous pollutants that are continuously released into the water over time, becoming an intrinsic source of pollution to the river's aquatic environment. Therefore, the management of rural rivers often relies on manual or mechanical cleaning of riverbed sediment. This method is effective and can quickly reduce the impact of riverbed sediment on river water quality, but it consumes a lot of manpower and material resources, and its effectiveness gradually fades with the accumulation of sediment. Its maintenance cost is high and requires regular investment. In recent years, water purification chemical treatment has become the simplest and fastest way to manage rivers. However, the application plan of the purification chemical needs to be determined according to different parameters such as riverbed sediment, water level, and water flow. However, the complex environmental factors of field experiments make it difficult to conduct relevant experiments to obtain relevant parameters. The uncertainty of the application plan has become a major obstacle to the promotion and application of the technology. Therefore, it is urgent to develop an indoor experimental device that simulates the water environment management of rural rivers to quickly and accurately formulate chemical treatment plans.

[0030] Before using the equipment, the composite microbial active conditioner is poured into the drug tank 108, the riverbed sludge is poured into the sludge tank 105, and the collected river water is poured into the water tank 102. When the equipment is in use, parameters such as sludge thickness, dosage, and application interval can be input into the single-chip control unit 121 through the wireless transmission module 123 via the host computer. The single-chip control unit 121 drives the screw pump 119 through the motor drive module 122 to operate, transporting the riverbed sludge in the sludge tank 105 to the mixer 209 through the feed pipe 106. At the same time, the single-chip control unit 121 drives the booster pump I103 through the motor drive module 122 to operate, transporting the water in the water tank 102 to the mixer 209 through the water pipe 104. After the sludge and water are mixed in a certain proportion in the mixer 209, they are sprayed through the nozzle 210 to the position pointed by the robotic arm IV208. The single-chip microcomputer control unit 121 drives motors I, II, III, and IV via the motor driver module 122. With the cooperation of motors I, II, III, and IV, the manipulator module 2 can reach any location on the inner wall of the channel module 4. The single-chip microcomputer control unit 121 drives the electric drive wheel 111 via the motor driver module 122. Driven by the electric drive wheel 111, the overhead crane module 1 advances along the track 401 at a constant speed set by the parameters until the entire channel module 4 is covered with the required thickness of riverbed mud according to the parameters. After the bottom mud is laid, the single chip control unit 121 drives the orifice plate motor 116 and the air pressure pump 107 to work through the motor drive module 122. When the granular composite microbial active conditioning agent passes through the limiting cone 114 and enters the holes on the array orifice plate 115, under the rotation of the orifice plate motor 116, the upper and lower sides of the holes on the array orifice plate 115 are aligned with the air nozzle 117 and the drug delivery tube 109 respectively. The air pressure pump 107 presses the composite microbial active conditioning agent in the hole into the drug delivery tube 109 through the air delivery tube 118 and the air nozzle 117, and finally implants it into the direction pointed by the robotic arm IV208 through the drug nozzle 211. In the riverbed mud, the single-chip control unit 121 drives motor I, motor II, motor III, and motor IV to work through the motor drive module 122. With the cooperation of motor I, motor II, motor III, and motor IV, the operating arm module 2 can reach any position of the inner wall of the channel module 4. At the same time, the single-chip control unit 121 drives the electric driving wheel 111 to rotate through the motor drive module 122. The overhead crane module 1 moves forward at a constant speed according to the speed set by the parameters under the drive of the electric driving wheel 111 until the conditioning agent is implanted into the riverbed mud inside the entire channel module 4 according to the parameter settings.After the conditioning agent is implanted, the single-chip control unit 121 drives motors I, II, III, and IV via the motor driver module 122. With the cooperation of motors I, II, III, and IV, the operating arm module 2 folds and retracts into the overhead crane module 1 through the landing port 110. To begin the test, water is supplied to the head water tank 301 of the head module 3. The water flows out through the water outlet 302, passes through the muddy surface of the channel 402, and finally enters the water collection tank 502 through the water outlet 503 and the filter structure 501. The water then flows through the water collection pipe 305, the nitrogen and phosphorus detection sensor 306, the booster pump II 303, and the drain pipe 304 into the head water tank 301. The microcontroller control unit 121 controls the Doppler flow sensor 113 and the ultrasonic water level sensor 112, feeding back the measured flow rate and water level information to the microcontroller control unit 121. This in turn regulates the booster pump II 303 to ensure that the flow rate in channel 402 meets the pre-set parameters for the experiment. At the time specified in the treatment method, the microcontroller control unit 121 controls the nitrogen and phosphorus detection sensor 306 to collect nitrogen and phosphorus content information.

[0031] When the test is complete, the microcontroller control unit 121 drives the water pump 505 via the motor driver module 122, draining the water in the channel 402 through the drain pipe 504. The microcontroller control unit 121 also drives the booster pump I 103 via the motor driver module 122, transporting the water in the water tank 102 through the water pipe 104 to the mixer 209, where it is sprayed through the nozzle 210 toward the location indicated by the robotic arm IV 208. The microcontroller control unit 121 drives the motors I, II, III, and IV via the motor driver module 122. With the coordination of motors I, II, III, and IV, the manipulator arm module 2 can reach any location on the inner wall of the channel module 4, flushing away any sludge therein. The mud-water mixture is finally discharged through the drain pipe 504 by the water pump 505.
