Description

Technical Field

[0001] The present invention belongs to the technical field of water quality monitoring, and in particular relates to a water quality monitoring device for environmental protection. Background Art

[0002] As an important part of environmental protection, water quality monitoring is not only important for evaluating the quality of water bodies, but also for providing a scientific basis for the protection, management and utilization of water resources.

[0003] Existing water quality monitoring devices include float-type, pole-type, and portable devices. Float-type devices are unaffected by flow velocity, offer flexible deployment, and are suitable for deep or highly mobile water bodies. However, existing water quality monitoring devices have some significant functional deficiencies: First, they cannot preserve water samples promptly, which is particularly critical when immediate analysis is required. Prompt preservation of water samples is crucial for ensuring the accuracy and validity of test data, but current equipment struggles to meet this basic requirement. Second, even if the device successfully preserves water samples, it cannot be transferred promptly. Water samples need to be quickly transferred to a laboratory or other suitable analytical environment for further testing. However, the lag in existing devices can cause the water samples to deteriorate or become contaminated during transfer, thus affecting the final analytical results. Furthermore, because the internal pipes of the devices remain wet during the pumping process, this not only easily leads to the growth of microorganisms on the inner walls of the pipes, but can also affect the purity of the water samples due to residual water stains, which in turn seriously affects the accuracy of testing. These issues prevent existing water quality monitoring devices from fully meeting the needs of high-quality testing, and urgent technical improvements are needed to enhance their performance and reliability.

[0050] During specific use, according to the monitoring requirements, the hoisting system 2 is used to fix the detection point, the hoisting motor 202 is started, and the hoisting roller 203 is driven to rotate by the hoisting motor 202 to release the anchor chain 204 wound on the hoisting roller 203, and the folding anchor 207 is dropped by the anchor chain 204 to fix the device body; when performing the detection operation, the sampling system 3 is used to take samples, and the monitoring system is used to monitor the values. When sampling, the isolation switch 303 and the exhaust switch 310 are first started to connect the pressure channel 302 with the shunt pipe 305, and the top of the shunt pipe 305 is connected to the outside world, and then the air pump 301 is started, and the air pump 301 pumps air into the pressure channel 302. When the air passes through the narrow section of the pressure channel 302, the air flow rate increases and the pressure decreases, forming a negative pressure area. The water sample in the sampling pipe 304 is sucked into the pressure channel 302, and the water sample enters the diversion pipe 305 from the pressure channel 302. The air is discharged from the upper end of the diversion pipe 305, and the water sample enters the monitoring system from the lower end of the diversion pipe 305; the water sample is tested for basic values ​​in the monitoring system, including pH value, conductivity, turbidity and temperature. The interior of the detection cabin 401 can be equipped with a pH detector, a conductivity detector, a turbidity detector and an electronic thermometer, and the probes (or detection heads) of the above detection equipment can be inserted into the detection tube 403. When the water sample is discharged from the diversion pipe 305, the water sample enters the monitoring system. After the lower end enters the detection tube 403, it can be directly tested. When there is no abnormality in the various values, the drainage switch 407 is turned on, and the water sample will be discharged from the floating chamber 6 through the branch pipe at one end of the branch pipe 404. When the detected values ​​are abnormal, the sample storage operation will be performed. When the sample storage operation is performed, the docking device 502 performs the main operation of sample storage. First, the opening and closing push arm 505 is started, and the opening and closing push arm 505 is extended. The rubber suction cup 506 at the end of the opening and closing push arm 505 contacts the side wall of the carrying base 508. The air in the rubber suction cup 506 is squeezed out and negative pressure is formed inside. At this time, the opening and closing push arm 505 contracts to draw the carrying base 508 out of the sample storage chamber 503, and then the docking push arm 504 is extended. The long push test tube rack 510 slides on the slide groove 509, pushing the sample test tube 511 that has not been injected with the water sample to the bottom of the injection head 406. During the test tube rack 510, the test tube rack 510 pulls the reset slider 513 to slide through the pulling line 512, and the reset slider 513 squeezes the reset spring 514 when sliding. After the sampling is completed, the docking push arm 504 contracts, and the elastic force generated by the restoration of the reset spring 514 pushes the reset slider 513 to move. The reset slider 513 pulls the test tube rack 510 to reset through the pulling line 512. The opening and closing push arms 505 and the docking push arms 504 are both contracted at equal intervals to ensure that the sample test tube 511 can be correctly aligned under the injection head 406.When the sample tube 511 is aligned under the injection head 406, the sample switch 405 is started. Since the branch tube 404 is connected to the detection tube 403, the air pressure of the sampling pipe 304 in the detection tube 403 will squeeze the water sample in the detection tube 403 to the branch tube 404 and the injection head 406 in turn. The pressure increase in the injection head 406 will push the docking slider 410 to slide downward, and the docking slider 410 will slide downward and insert into the sample tube 511. At the same time, the docking slider 410 will squeeze the sealing spring 411, and the inside of the sample tube 511 will be negative pressure. After the docking slider 410 is inserted into the sample tube 511, the water sample in the injection head 406 will be Inject it into the sample tube 511. When a sufficient amount of water sample is placed in the sample tube 511, the pressure in the sample tube 511 and the pressure in the injection head 406 tend to be consistent. At this time, the water sample stops entering the sample tube 511. At this time, the drain switch 407 is turned on, the sample switch is closed, and the sealing spring 411 recovers and pushes the docking slider 410 upward. The docking slider 410 is separated from the sample tube 511. At the same time, the docking slider 410 is tightly attached to the sealing disk 409. After the sampling is completed, the docking push arm 504 is retracted, the test tube rack 510 is reset, and the opening and closing push arm 505 is extended to close the carrying base 508 and the sample chamber 503. After a period of time, the rubber Air penetrates into the suction cup 506, and the rubber suction cup 506 is separated from the carrying base 508; when it is necessary to transfer the sample storage cabin 503, it is only necessary to start the double-fork lifting base 501, adjust the height of the double-fork lifting base 501 to lift the sample storage cabin 503, and during the rising process of the double-fork lifting base 501, the sealing slide 602 will be pushed to slide through the linkage rod 603, exposing the exchange port 601, making it easy to push the sample storage cabin 503 out of the floating cabin 6, and then the sample storage cabin 503 can be replaced manually or by using a drone; when monitoring is suspended, first close the exhaust switch 310 and the sample storage switch 405, and open the drain switch 407 and the isolation switch Close 303, reducing the power of the air pump 301 and the flow rate of gas through the pressure channel 302 to reduce the negative pressure in the narrow tube. The remaining water sample will be discharged through the branch pipe 404. Then close the drain switch 407 and the isolation switch 303. At this time, the gas will be discharged through the sampling pipe 304, draining the water in the sampling pipe 304. Then close the air pump 301 to prevent the sampling pipe 304 from prolonged contact with the water and causing internal contamination. For the next test, keep the isolation switch 303 closed and start the air pump 301. The air will squeeze out the remaining water at the bottom of the sampling pipe 304, preventing it from affecting the next test.

[0051] The isolating switch 303 is the same type of magnetic switch as the exhaust switch 310, the sample storage switch 405 and the liquid discharge switch 407, and has the same working principle. When the isolating switch 303 is turned on, the opening and closing electromagnet 309 is started, and the opening and closing electromagnet 309 adsorbs the single-hole channel 307. The single-hole channel 307 slides in the magnetic sliding cavity 306 and squeezes the magnetic spring 308. At this time, the isolating switch 303 is in the on state. When the isolating switch 303 is closed, the opening and closing electromagnet 309 is closed, and the magnetic spring 308 is reset to push the single-hole channel 307 to slide. At this time, the isolating switch 303 is in the off state.

[0052] The energy supply system 1 is responsible for energy storage, signal transmission and signal warning. By changing the length of the telescopic arm 104, the angle of the photovoltaic panel 103 is adjusted accordingly. When the telescopic arm 104 is extended, the telescopic end of the telescopic arm 104 pushes the adjustment push arm 106 through the connector. Since the upper end of the photovoltaic panel 103 is connected to the mounting bracket 102, the photovoltaic panel 103 will rotate under the push of the adjustment push arm 106, and the vertical angle of the photovoltaic panel 103 will increase. The length of the extension of the telescopic arm 104 can be controlled according to the dimension to change the rotation angle of the photovoltaic panel 103, so that the angle between the photovoltaic panel 103 and the sunlight is close to 90 degrees, so as to improve the energy conversion efficiency. The signal light 108 uses optical fiber to provide warnings, and also facilitates the drone to find targets. The signal antenna 109 can receive and send information.
