Description

Technical Field

[0001] The invention relates to the technical field of water quality sampling and detection, and in particular to a water quality detector for environmental monitoring. Background Art

[0002] Meteorological services involve marine environmental water quality meteorological monitoring buoys, which are used to monitor water quality changes caused by meteorological reasons. At the same time, marine environmental monitoring buoys: buoys that integrate water quality monitoring and meteorological monitoring functions, can simultaneously monitor marine environmental parameters such as seawater temperature, salinity, flow rate, and flow direction. With the rapid development of industrialization and urbanization, environmental issues are becoming increasingly important, which has had a huge impact on the quality of water resources. Accurate and timely monitoring of water quality is crucial to environmental protection, maintenance of ecological balance, and human health.

[0003] The existing marine environment water quality meteorological monitoring buoy can only sample pool water at the same depth when sampling. However, pool water at different depths has different water quality characteristics. The surface of the water body may be affected by factors such as light and air pollution, while the water quality at the bottom may be different due to sediments, microbial decomposition, etc. Therefore, if only the water quality at one depth is taken during the sampling process, the experimental data will be inaccurate. Traditional water quality testing equipment discharges after sampling, and does not save the samples collected from the pool water. Therefore, it is impossible for researchers to compare the water quality at the same depth at different time points. At the same time, the water inlet is easily blocked by impurities, silt, algae, microorganisms, etc. in the water during use. Once blocked, it will lead to poor water inflow, affecting the normal collection of water samples, and then making the test data inaccurate or unable to obtain, delaying the monitoring and analysis of water quality.

[0047] A sample storage bottle 30 is fixedly connected to the top of each fixed rod 29, and a water quality parameter sensor is arranged at the bottom of the inner cavity of each sample storage bottle 30, which can measure the corresponding water quality parameters in real time and provide data support for water quality monitoring. An electric telescopic rod 31 is fixedly installed at one end of each fixed rod 29 away from the second disk 26, and the drainage pipe of the sample storage bottle 30 is located directly above the electric telescopic rod 31. Two fixed recessed blocks 32 are fixedly connected to the bottom of the inner cavity of the floating shell 1, and a resistance plate 33 is slidably connected between the two fixed recessed blocks 32. A spring 34 is fixedly connected between the resistance plate 33 and the fixed recessed block 32. The end of the resistance plate 33 close to the second disk 26 is rotatably connected to a swivel 35, and a reset plate 2 36 is fixedly installed on the side of the fixed recessed block 32 close to the second disk 26. The swivel 35 and the end of the reset plate 2 36 away from the eccentric cylinder 24 are in contact with each other, and the output shaft end of the electric telescopic rod 31 located directly below the fixed funnel 17 is in conflict with the inner wall of the floating shell 1, and the end of the swivel 35 away from the fixed recess 32 is in conflict with the arc-surface protrusion of the disk 26. A float pull-rope switch 37 is fixedly installed at the bottom of the inner cavity of each sample storage bottle 30. The float pull-rope switch 37 consists of a float, a pull rope and a travel switch, and the float is made of plastic, stainless steel and other materials, and is used to detect changes in water level. It will float as the water level rises or falls. The pull rope is made of nylon rope and other materials, and is used to connect the float and the travel switch. The travel switch is used to trigger the switch action when the float reaches the set position, thereby controlling the operation of the electric telescopic rod 31.

[0048] The above implementation works as follows:

[0049] The initialization steps are as follows:

[0050] The floating airbag 3 is filled with air, so the staff places the floating shell 1 on the water surface where the water quality needs to be tested. The floating airbag 3 increases the buoyancy of the floating shell 1 to float on the water surface. The water surface below may include ponds, rivers, etc. The float rope switch 37 is in a retracted state.

[0051] The working steps are as follows:

[0052] The working steps of the rotating telescopic assembly are as follows:

[0053] After the stepper motor 2 is energized, it drives the rotating column 4 to start rotating, and the rotating column 4 drives the cylinder 5 to rotate. Therefore, the cylinder 5 passes through the sliding groove 7 and the extrusion convex plate 8, so that the cylinder 5 drives the sliding column 6 to move synchronously. At this time, the sliding column 6 drives the rotating column 2 11 to rotate in the inner cavity of the fixed circular shell 9, so that the rotating column 2 11 drives the fixed cylinder 12 to slide along the trajectory of the spiral groove 10, so that the fixed cylinder 12 drives the rotating column 2 11 to continuously descend. At this time, the rotating column 2 11 also drives the sliding column 6 to move vertically downward, so the convex plate 8 on the sliding column 6 slides vertically downward on the sliding groove 7, so that the vertical position of the bottom of the rotating column 2 11 in the water continues to decrease, thereby realizing the sampling of water quality at different depths.

[0054] The working steps of the sampling assembly are as follows:

[0055] As the bottom of the rotating column 11 continues to drop in the vertical position in the water, the rotating column 11 drives the hose 15 to move vertically downward continuously, so the hose 15 continuously drives the rotating frame 14 to roll, and the rotating frame 14 pulls up the bellows of the hose 15, thereby ensuring that the bottom of the hose 15 moves vertically downward synchronously with the rotating column 11.

[0056] When it is necessary to sample water at different depths, the stepper motor 2 stops driving to ensure that the rotating column 11 stays in the corresponding position. At this time, the sampling chamber 13 opens the solenoid valve through the controller, and the pool water continuously enters the interior of the sampling chamber 13. After the pool water fills the interior of the sampling chamber 13, the solenoid valve is closed, and then the suction pump of the hose 15 is energized and started to suck the pool water inside the sampling chamber 13. The pool water flows along the inner cavity of the hose 15 into the water outlet pipe 16, and the water outlet pipe 16 discharges the pool water into the fixed funnel 17, so that the pool water falls vertically through the fixed funnel 17 under the action of its own gravity.

[0057] By cooperating with the rotating telescopic component and the sampling component, it is possible to sample pool water at different depths. By extracting pool water at different depths for testing, the water quality of the entire water body can be understood more comprehensively and accurately, avoiding one-sided judgments on the overall water quality based on the test results obtained from sampling pool water at a single depth. This makes water quality test data more accurate, thereby effectively increasing the portability of meteorological services.

[0058] The steps for storing sample components are as follows:

[0059] When the pool water falls vertically through the fixed funnel 17 under the action of its own gravity and enters the sample storage bottle 30, the inner cavity of the sample storage bottle 30 continuously stores the pool water. At this time, the water quality parameter sensor at the bottom of the inner cavity of the sample storage bottle 30 detects the water quality of the pool water, thereby realizing real-time measurement of the corresponding water quality parameters, providing data support for water quality monitoring, and when the pool water is submerged to above the middle of the sample storage bottle 30, the floating ball in the float pull-string switch 37 also comes to a position above the middle of the sample storage bottle 30 as the water level rises, so that the float in the float pull-string switch 37 The floating ball triggers the travel switch by pulling the pull rope, so that the electric telescopic rod 31 is powered on and begins to extend. At this time, the extended shaft end of the electric telescopic rod 31 contacts the inner wall of the floating shell 1. According to the force, as the electric telescopic rod 31 continues to extend, one end of the electric telescopic rod 31 close to the fixed funnel 17 contacts the side wall of the floating shell 1, so the other end away from the electric telescopic rod 31 starts to push the contact plate 33 to move toward the fixed concave block 32. Therefore, the contact plate 33 is limited in the horizontal direction by the fixed concave block 32. The contact plate 33 drives the swivel 35 to push the disk 26 and compress the spring 34. The swivel 35 is resisted by the reset plate 26. The memory elastic force of the reset plate 26 always resists the side of the swivel 35. The swivel 35 and the reset plate 26 jointly exert a vertical downward force to move the disk 26. The disk 26 starts to rotate. The swivel 35 passes through the smooth curved surface of the disk 26, so that the swivel 35 again resists the arc surface convex block of the disk 26 after rotating 90 degrees. At the same time, the disk 26 The rotation drives the rectangular rotating block 27 to start rotating. The rectangular rotating block 27 rotates through the smooth curved surface to open the resistance of the reset piece 28. The reset piece 28 is elastically deformed by the rotation force of the rectangular rotating block 27. When the rectangular rotating block 27 rotates ninety degrees and stops rotating, the reset piece 28 remembers the elastic force and clamps the rectangular rotating block 27 again. At this time, the ninety-degree rotation of the disk 26 drives the fixed rod 29. The ninety-degree rotation of the fixed rod 29 drives the sample storage bottle 30 and the electric telescopic rod 31 to rotate synchronously ninety degrees, thereby forming the effect of replacing the sample storage bottle 30.

[0060] Therefore, the staff extracts the pool water from the inner cavity of the sample storage bottle 30 at regular intervals.

[0061] By coordinating the rotating telescopic component with the sample storage component, pool water samples of different depths can be retained, which is convenient for staff to conduct more comprehensive testing after taking them out. At the same time, a water quality database can be established after the sampled pool water is preserved. By analyzing pool water samples of different depths preserved at different time points, the long-term change trend of water quality can be understood. At the same time, it is convenient to establish a water quality database for meteorological services and reduce errors caused by no sample retention.

[0062] The working steps of cleaning components are as follows:

[0063] When sampling of different pool water is not performed, along with the rotation of rotating column 14, rotating column 14 drives rotating column 3 18 to rotate synchronously through synchronous belt 19, so rotating column 3 18 continuously rotates disc 1 20 with its own circle as the axis, and disc 1 20 drives its eccentrically arranged eccentric cylinder 24 to perform circular motion with the center of disc 1 20 as the axis, and the eccentric cylinder 24 continuously pushes sliding groove 23 to drive the swing rod 22 to perform circular motion with the center of rotating column 4 21 as the axis, so disc 1 20 performs one circle, and swing rod 22 swings back and forth once, and swing rod 22 drives cleaning brush head 25 to continuously resist the pipe mouth of water outlet pipe 16.

[0064] Similarly, when sampling is completed, when the stepper motor 2 reverses, the pool water is no longer sucked. As the stepper motor 2 reverses, the same steps are repeated to continuously wipe the water outlet pipe 16 after the pool water is taken.

[0065] By setting up the cleaning component, the pipe mouth of the water outlet pipe 16 can be cleaned, thereby preventing long-term attachment and reproduction of microorganisms in the pool water during the sampling process, resulting in the formation of biofilm blocking the water inlet, ensuring that the water sample can continuously and stably enter the sample storage bottle 30, and avoiding incomplete or inaccurate water sample collection due to poor water inlet.
