Description

Technical Field

[0001] The invention belongs to the technical field of environmental monitoring, and in particular relates to an environmental monitoring collection device. Background Art

[0002] With the improvement of social living standards and the rapid development of industrialization, the discharge of various garbage and sewage is increasing. Therefore, people are paying more and more attention to environmental governance. Environmental governance first requires environmental testing, including sewage testing. Before testing, it is necessary to collect microorganisms in water at different depths.

[0003] In the prior art (the announcement number is CN112834285B, and the patent name is a sewage collection device for water environment detection), a submersible chamber and a sampler are combined. The submersible chamber is the main body, and a driving device is installed on the submersible chamber. A plurality of shell units are installed on the axial circumference of the driving device. The shell unit is connected to the submersible chamber by means of a connecting rod. The connecting rod, the submersible chamber and the shell unit are all hinged. The driving device can drive the shell unit to close and open along the axial direction. After the shell unit is completely closed, a sealed space is formed between the shell units to accommodate water samples. During the working process, the submersible chamber first sinks below the water surface and adjusts to the depth position to be collected. At this time, a suspended stable state is maintained. After stabilization, the driving device is started to drive the shell unit to close. The surrounding shell units converge toward the center, and the adjacent shell units are butt-sealed. After several shell units are closed, a sealed space is formed. During the closing process of the shell unit, the suspension is stable, the water sample disturbance is small, and the water sample integrity is achieved. In the process of implementing this technical solution, it is found that at least the following problems exist in the prior art.

[0004] There are some significant shortcomings in the traditional water quality monitoring sampling method. When researchers try to obtain water samples at a specific depth, the sampling equipment will inevitably enter waters at other depths, resulting in the collected water samples not fully representing the water quality conditions at the target depth. This cross-contamination phenomenon causes deviations in the test results and affects the accuracy of the data. In addition, water samples often contain suspended particles such as mud and sand. These debris can easily interfere with the equipment and affect the reliability of the test results. Especially when sampling rivers, the presence of aquatic plants and floating objects is a thorny problem. Since these substances are difficult to be effectively filtered, they can cause blockage or even damage inside the device. Summary of the invention

[0017] An environmental monitoring and collection device of the present invention:

[0018] 1. The environmental monitoring and collection equipment first fixes one end of the rope on the steel rope connecting ring, and puts the device into the water area that needs to be tested. When the driving motor drives the rotating rod to rotate counterclockwise, the rotating rod drives the active bevel gear to rotate, and the active bevel gear drives the driven bevel gear and the rotating rod to rotate. The rotating rod drives the propeller to rotate, and the propeller sucks water into the suction and pressure cylinder through the filter inlet pipe to increase the gravity of the device, and the excess water is discharged from the drain pipe. The propulsion force generated by the discharged water flow can accelerate the sedimentation speed of the equipment and quickly reach the predetermined detection water area. In this way, not only the sampling time is greatly shortened, but also the work efficiency is significantly improved.

[0019] 2. The environmental monitoring and collection equipment, before reaching the detection water area, when the rotating rod rotates counterclockwise, the double-ended gravity ball rod moves in the top straight groove in the guide groove, so that the sealing mechanism is in a sealed state. When reaching the detection water area, the driving motor drives the rotating rod to rotate clockwise, and the rotating rod drives the limiting column to rotate. When the double-ended gravity ball rod passes above the oblique groove of the guide groove, the double-ended gravity ball rod falls into the oblique groove of the guide groove through the gravity of the end, so that the guide groove pushes one end of the double-ended gravity ball rod to move to the bottom straight groove of the guide groove, so that the double-ended gravity ball rod pulls the connecting plate to move through the hollow card ball, and the connecting plate drives the rotating ring to rotate. The rotating ring pulls the push-pull rod to move through the hinge seat, so that the push-pull rod pulls the sealing plate through the hinge rod, and the sealing plate moves with the axial rod as the axis, thereby opening the sealing mechanism, ensuring that only water samples of the target depth enter the water suction cylinder, and preventing water samples of other depths from entering the water suction cylinder to cause cross contamination, thereby causing deviations in the detection results and affecting the accuracy of the data.

[0020] 3. The rotating rod drives the inclined circular plate to rotate, and the inclined circular plate pushes and pulls the lifting hollow tube to perform reciprocating lifting motion. Because the friction between the piston and the connecting bracket is greater than the friction between the piston and the lifting hollow tube, when the lifting hollow tube drives the lifting cylinder to rise, the lifting hollow tube rising piston does not move, and the lifting cylinder needs to pull the piston to move. When the piston contacts the lifting cylinder, the piston blocks the water absorption hole, so that negative pressure is generated at the bottom of the piston, and the blocking ball releases the blockage of the blocking port, so that water can enter the water absorption cylinder from the blocking port. When the lifting hollow tube drives the lower pressure ring to descend, the lower pressure ring Push the piston down to expose the water absorption hole, and the blocking ball will seal the sealing port during the descending process, which can minimize the disturbance of the device to the water sample, thereby ensuring that the integrity of the water sample is enhanced. After the sealing is completed, the piston squeezes the water inside the water absorption cylinder, and the squeezed water enters the lifting hollow tube through the water absorption hole and is discharged from the lifting hollow tube into the U-shaped connecting tube, so that the water enters the sampling bottle, achieving the effect of water sampling. This design not only improves the sampling efficiency, but also ensures the accuracy and reliability of the sampling process.

[0021] 4. In the process of absorbing water, impurities in the water are filtered by the filter cartridge, and the impurities are adsorbed on the filter cartridge. The rotating rod drives the pressure block to rotate, and the pressure block pushes one end of the lifting rod to descend, so that the other end of the lifting rod is lifted. When the pressure block is not in contact with the lifting rod, the impact ball descends by its own gravity, thereby impacting the filter cartridge to make it vibrate, so that the impurities adhering to the filter cartridge are effectively separated, and the solid impurities are prevented from accumulating on the filter cartridge, which is convenient for extending the maintenance cycle of the device, and the maintenance cost is low. The rotating rod drives the L-shaped scratching sheet to rotate, and the L-shaped scratching sheet can be tightly attached to the filter cartridge, so that the cleaning effect is better, which not only improves the service life of the equipment, but also reduces the manpower and material costs during the maintenance process. At the same time, a cutting knife is also provided at the bottom of the rotating rod, which can be driven by the rotating rod to rotate the cutting knife. The cutting knife can effectively cut and separate aquatic plants in the water body, so as to avoid these plants from interfering with and hindering the movement and diving operation of the device. In addition, cutting aquatic plants can also prevent them from being entangled in the water, thereby ensuring that the device can smoothly carry out various operations and improve operating efficiency and safety.

In this way, not only the sampling time is greatly shortened, but also the work efficiency is significantly improved. The top of the counterweight circular plate 103 is fixedly connected with A connecting frame 73, the side wall of which is rotatably connected to a blocking plate 74, the bottom of which is fixedly connected to a connecting spring 75, and one end of the connecting spring 75 away from the blocking plate 74 is fixedly connected to the top of the counterweight circular plate 103. This arrangement is such that when the driving motor 21 drives the rotating rod 22 to rotate clockwise, the drain pipe 72 generates suction, so that the connecting spring 75 drives the blocking plate 74 to block the drain pipe 72, preventing water from entering from the drain pipe 72 and being discharged from the filter water inlet pipe 71, thereby preventing the device from rising during the sampling process.

[0051] The working principle of an environmental monitoring and collection device: first, fix one end of the rope on the steel rope connecting ring 101, and put the device into the water area to be tested. When the driving motor 21 drives the rotating rod 22 to rotate counterclockwise, the rotating rod 22 drives the active bevel gear 701 to rotate, and the active bevel gear 701 drives the driven bevel gear 705 and the rotating rod 703 to rotate. The rotating rod 703 drives the propeller 704 to rotate. The propeller 704 sucks water into the suction and pressure cylinder 706 through the filter water inlet pipe 71 to increase the gravity of the device, and the excess water is discharged from the drain pipe 72. Through the propulsion force generated by the discharged water flow, the device can accelerate its sedimentation speed and quickly reach the predetermined detection water area. In this way, not only the sampling time is greatly shortened, but also the work efficiency is significantly improved;

[0052] When the detection water area is not reached, the rotating rod 22 rotates counterclockwise, so that the double-end gravity ball rod 504 moves in the top straight groove in the guide groove 502, so that the sealing mechanism 4 is in a sealed state. When the detection water area is reached, the driving motor 21 drives the rotating rod 22 to rotate clockwise, and the rotating rod 22 drives the limiting column 501 to rotate. When the double-end gravity ball rod 504 passes above the inclined groove of the guide groove 502, the double-end gravity ball rod 504 falls into the inclined groove of the guide groove 502 by the gravity of the end, so that the guide groove 502 pushes one end of the double-end gravity ball rod 504 to move to the bottom straight groove of the guide groove 502, so that the double-end gravity ball rod 504 is The end gravity ball rod 504 pulls the connecting plate 506 to move through the hollow card ball 505, and the connecting plate 506 drives the rotating ring 403 to rotate. The rotating ring 403 pulls the push-pull rod 406 to move through the hinge seat 405, so that the push-pull rod 406 pulls the sealing sheet 408 through the hinge rod 407, and the sealing sheet 408 moves with the axis rod 409 as the axis, so as to open the sealing mechanism 4, ensuring that only water samples of the target depth enter the water absorption cylinder 204, and preventing water samples of other depths from entering the water absorption cylinder 204 to cause cross contamination, thereby causing deviations in the detection results and affecting the accuracy of the data;

[0053] The rotating rod 22 drives the inclined circular plate 23 to rotate, and the inclined circular plate 23 pushes and pulls the lifting hollow tube 203 to perform reciprocating lifting motion. Because the friction between the piston 304 and the connecting bracket 205 is greater than the friction between the piston 304 and the lifting hollow tube 203, when the lifting hollow tube 203 drives the lifting cylinder 303 to rise, the piston 304 does not move when the lifting hollow tube 203 rises, and the lifting cylinder 303 needs to pull the piston 304 to move. When the piston 304 contacts the lifting cylinder 303, the piston 304 blocks the water absorption hole 301, so that negative pressure is generated at the bottom of the piston 304, and the blocking ball 306 releases the blocking of the blocking port 307, so that water can enter the water absorption cylinder 204 from the blocking port 307. When the lifting hollow tube 2 When the lower pressure ring 302 is driven to descend, the lower pressure ring 302 pushes the piston 304 to descend, thereby exposing the water absorption hole 301, and the blocking ball 306 blocks the blocking port 307 during the descending process, so as to minimize the disturbance of the device to the water sample, thereby ensuring that the integrity of the water sample is enhanced. After the blocking is completed, the piston 304 squeezes the water inside the water absorption cylinder 204, and the squeezed water enters the lifting hollow tube 203 through the water absorption hole 301, and is discharged from the lifting hollow tube 203 into the U-shaped connecting tube 201, so that the water enters the sampling bottle 106, achieving the effect of sampling the water sample. This design not only improves the sampling efficiency, but also ensures the accuracy and reliability of the sampling process;

[0054] During the water absorption process, impurities in the water are filtered by the filter cartridge 602, and the impurities are adsorbed on the filter cartridge 602. The rotating rod 22 drives the pressing block 607 to rotate, and the pressing block 607 pushes one end of the lifting rod 605 to descend, so that the other end of the lifting rod 605 is lifted. When the pressing block 607 is not in contact with the lifting rod 605, the impact ball 606 falls by its own gravity, thereby hitting the filter cartridge 602 to make it vibrate, so that the impurities adhering to the filter cartridge 602 can be effectively separated, and the solid impurities can be avoided from accumulating on the filter cartridge 602, which is convenient for extending the maintenance period of the device, and the maintenance cost is low. The rotating rod 22 drives the L-shaped scratching plate 6 08 rotation, the L-shaped scratching sheet 608 can be tightly attached to the filter cartridge 602, so that the cleaning effect is better, which not only improves the service life of the equipment, but also reduces the manpower and material costs in the maintenance process. At the same time, a cutting knife 609 is also arranged at the bottom of the rotating rod 22, and the cutting knife 609 can be driven to rotate by the rotating rod 22. The cutting knife 609 can effectively cut and separate the aquatic plants in the water body, so as to avoid these plants from interfering with and hindering the movement and diving operation of the device. In addition, cutting the aquatic plants can also prevent them from being entangled in the water, thereby ensuring that the device can smoothly carry out various operations and improve the working efficiency and safety.
