Description

Technical Field

[0001] This invention relates to the field of environmental monitoring technology, specifically to an environmental monitoring device that can be quickly assembled. Background Technology

[0002] Water quality monitoring is an important foundation for environmental protection, water resource management, and water pollution control. It is necessary to monitor indicators such as pH value, dissolved oxygen, turbidity, and heavy metal content in various water bodies, including rivers, lakes, groundwater, and industrial wastewater.

[0003] Currently, my country's water quality monitoring technology mainly relies on physicochemical monitoring. Among existing technologies, establishing multiple water quality monitoring stations can achieve automatic continuous monitoring, but the construction cost is high. Therefore, the most common method of water quality monitoring is still to conduct it manually on-site. Staff collect water samples from the monitored water body on-site, and on-site instruments perform online data analysis of the monitored water body. Alternatively, advanced portable multi-parameter water quality monitoring instruments can be used to directly monitor and analyze the water body.

[0004] However, this method of water quality monitoring requires staff to go to the shore to carry out monitoring operations. The staff's labor intensity is high, especially when working in the field, where the environment is harsh. Moreover, there are safety hazards when environmental staff use on-site instruments to monitor water quality on the shore or near aquatic plants, resulting in low reliability. With the development of technology, staff have begun to use drones equipped with sampling devices to fly to the water body to collect samples.

[0005] When unmanned aerial vehicle (UAV) sampling equipment samples water in flowing water, if the sampling device is not heavy enough, it is easily tilted by the flowing water, which affects the accuracy of the water depth sampled.

[0006] A water pollution monitoring drone device is disclosed in publication number CN117129281B. The device includes a drone body with a cylindrical casing at its bottom. A scale rod is installed inside the casing. Several locking blocks are evenly spaced at the bottom of the casing, with their lower ends located within annular grooves. These grooves are located at the top of a nut, which is threaded onto the scale rod. A hollow bracket is connected to the lower end of the scale rod, and a sampling cylinder for entering the water body is connected to the bottom of the hollow bracket. This water pollution monitoring drone device avoids contamination of the sample chamber and inlet from other depths of water when the sampling cylinder enters the water body, thus preventing the accuracy of the test data from being affected. Furthermore, after sampling, as the drone moves upwards out of the water body, the float plate moves upwards on the water surface, while the float ball detaches from the water surface support and moves downwards towards the bottom plate. This causes the vortex spring to reset the closing plate, sealing the inlet and preventing water samples from flowing out of the sample chamber, achieving a certain degree of automatic sampling.

[0007] In the aforementioned application, a corresponding number of annular counterweights are nested onto the sleeve column according to the speed of the water flow from the water source to be sampled. Then, the conical counterweights are threadedly connected and fixed to the bottom of the sleeve column, so that the subsequent sampling tube is not easily tilted due to the water flow when inserted into the water source. However, this method requires manual operation, which is inconvenient to use, and it will increase the power consumption of the drone during flight. Summary of the Invention

[0016] Preferably, a magnetic ring three with a notch on its surface is provided above the ring body. A rotating layer is fixed on the outer wall of the magnetic ring three.

The bottom end of the locking hole plate is fixedly connected to the protective cylinder.

[0019] Working principle: First, the stabilizing sphere is immersed in water. Water enters the stabilizing sphere through the opening, thereby increasing its weight and improving its ability to resist water flow impact. The water flow inside the stabilizing sphere causes the buoyancy layer to rise. When it rises to the top, the sealing plate moves and presses against the inner top wall of the upper chamber of the opening. The snap-fit ​​structure also locks the buoyancy layer, thus fixing its position. This causes the sealing plate to block the opening, preventing the water entering the stabilizing sphere from flowing out. As a result, the weight of the stabilizing sphere tends to stabilize, achieving the effect of stabilizing the sampling component.

[0020] This invention provides an environmental monitoring device that can be quickly assembled. It has the following beneficial effects: 1. The present invention features a stabilizing ball that automatically stores water and increases weight after entering the water to resist the impact of the water flow, and automatically drains water and reduces weight after sampling. No manual adjustment of the counterweight is required, which not only ensures accurate sampling depth but also reduces the power consumption of the drone, achieving the effect of automatic adjustment and stability to adapt to the water flow environment.

[0021] 2. This invention uses a dual-line take-up and release integrated machine, which allows the sampling component to slide along the taut suspension rope to take samples, making it suitable for use in turbulent waters and also allowing for precise adjustment of the sampling depth.

[0022] 3. The sampling component of this invention supports multiple automatic samplings, the sealed structure avoids sample contamination, and the design of the protective cylinder and sampling cleaning port facilitates the disassembly and assembly of the sampling cylinder and the cleaning of the equipment, achieving the effect of efficient and convenient sampling and expanding the monitoring range.

[0023] 4. This invention filters impurities in the incoming water through a filter plate, prevents silt from clogging the filter plate with a mud baffle, and opens the stabilizing ball during recycling to reduce recycling resistance, thereby improving the ease of use of the stabilizing components.

[0026] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1, please refer to the appendix. Figure 1 - Appendix Figure 2 This invention provides an environmental monitoring device for rapid assembly, including a mounting base 1 that can be detachably installed under a drone. A suspension rope 2 is provided below the mounting base 1, a sampling component 3 is installed on the surface of the suspension rope 2, and a stabilizing component 4 is installed at the bottom end of the suspension rope 2. The stabilizing component 4 includes a stabilizing ball 401 that is fixedly connected to the suspension rope 2. The stabilizing ball 401 is made of solid stainless steel. By pre-drilling a threaded hole at the bottom of the drone and opening a connection hole on the surface of the mounting base 1, the device can be quickly assembled onto the drone by passing a bolt through the connection hole and connecting it to the threaded hole.

[0028] Specifically, when monitoring water resources and the environment, a drone flies up to lift the stabilizing ball 401. When it reaches the predetermined monitoring point, the drone descends and steadily lowers the stabilizing ball 401 into the water, thereby reducing the impact of the water flow and keeping the suspension rope 2 taut. This allows the subsequent sampling component 3 to be inserted into the water source without being easily affected by the water flow and thus improving the positional accuracy of water resource sampling and monitoring.

[0029] Example 2, please refer to the appendix. Figure 2 - Appendix Figure 5 Because the solid stabilizing sphere 401 is heavy, it increases the additional power consumption of the drone during flight. Therefore, this embodiment differs from the solid stabilizing sphere 401 in that the stabilizing sphere 401 adopts a hollow metal structure to reduce weight and power consumption of the drone. The bottom of the stabilizing sphere 401 has a stepped opening 402, which includes a liquid inlet, an upper chamber, and a lower chamber from top to bottom. A sealing plate 403 is provided inside the opening 402. The diameter of the sealing plate 403 matches that of the upper chamber and is smaller than that of the lower chamber. A connecting rod 404 penetrating the stabilizing sphere 401 is fixed at the top of the sealing plate 403. A buoyancy layer 405 is fixed at the top of the connecting rod 404. A hollow tube 409 is provided inside the buoyancy layer 405. The bottom end of the hollow tube 409 is fixedly connected to the inner wall of the stabilizing sphere 401. A snap-fit ​​mechanism is provided inside the tube 409 to snap the buoyancy layer 405 when it rises to the top. The snap-fit ​​mechanism includes an installation cavity opened in the inner side wall of the buoyancy layer 405 and a slot 410 opened in the upper side wall of the hollow tube 409. A snap-fit ​​block 406 is slidably connected inside the installation cavity. An elastic element 407 is fixed between the snap-fit ​​block 406 and the installation cavity. The elastic element can be a steel leaf spring, a coil spring, a torsion bar spring, a rubber spring, etc., preferably a coil spring made of a corrosion-resistant material such as stainless steel. The sealing plate 403 includes a sealing ring and a flexible membrane layer fixed inside the sealing ring. When the sealing plate 403 rises to seal, the flexible membrane layer can cause some of the liquid inside the stabilizer to squeeze the flexible membrane layer, thereby increasing the space to store water in the upper chamber, so that the sealing plate 403 can rise to the inner top wall of the upper chamber.

[0030] Specifically, initially, the sealing plate 403 slides to the bottom, opening the opening 402. When the stabilizing ball 401 is immersed in water, water enters the stabilizing ball 401 through the opening 402, thereby increasing its weight and improving its ability to resist water flow impact. The water flow inside the stabilizing ball 401 drives the buoyancy layer 405 to rise. When it rises to the top, the sealing plate 403 moves to abut against the inner top wall of the upper chamber of the opening 402, and the snap-fit ​​structure locks the buoyancy layer 405, thereby fixing the position of the buoyancy layer 405. This causes the sealing plate 403 to block the opening 402, preventing the water entering the stabilizing ball 401 from flowing out, thus stabilizing the weight of the stabilizing ball 401 and achieving the effect of stabilizing the sampling component 3.

[0031] When the locking mechanism is in use, the locking block 406 presses against the outer wall of the hollow tube 409 by the elastic force of the elastic element 407, and when the buoyancy layer 405 rises to the top, the locking block 406 is aligned and inserted into the locking groove 410 under the action of the elastic force, thereby realizing the locking and limiting of the buoyancy layer 405.

[0032] Based on the above embodiments, please refer to the appendix. Figure 5Since it is difficult to drain water from the stabilizing ball 401 after it is filled with water, which will affect the flight endurance of the drone, this embodiment proposes the following solution to automatically drain the water from the stabilizing ball 401 to reduce its weight. The top of the hollow tube 409 extends through the stabilizing ball 401. A T-shaped buoyancy adjustment member 408 is slidably arranged inside the hollow tube 409. The adjustment member 408 needs to have a certain weight to counteract the upward pushing force exerted by the magnetic repulsion between the magnetic ring 1 411 and the toothed magnetic ring 2 412. The lower side wall of the adjustment member 408 is fixed with the magnetic ring 1 411. One end of the locking block 406 is fixed with the magnetic ring 2 412 that is magnetically repulsive to the magnetic ring 1 411. That is, the opposite surfaces of the magnetic ring 1 411 and the magnetic ring 2 412 are magnetically repulsive. The hollow tube 409 is provided with multiple channels. The upper and lower inner walls of the uppermost channel are respectively fixed with limiting layers 413. The limiting layers 413 are used to limit the adjustment member 408, so that the adjustment member 408 slides up and down in the uppermost channel.

[0033] Specifically, when the stabilizing ball 401 and the hollow tube 409 are immersed in water, the adjusting component 408 drives the magnetic ring 411 to rise, making the magnetic ring 411 higher than the magnetic ring 412. When the stabilizing ball 401 rises to the water surface after sampling, the adjusting component 408 drives the magnetic ring 411 to fall, making the magnetic ring 411 move to the position of the magnetic ring 412. Through the magnetic force of the two, the locking block 406 is automatically driven to slide into the mounting cavity, so that the locking block 406 exits the slot 410, realizing the automatic unlocking of the buoyancy layer 405. This causes the sealing plate 403 to fall and open the opening 402, allowing the water in the stabilizing ball 401 to be discharged, thereby reducing the weight carried by the UAV during subsequent flight, reducing the flight pressure of the UAV, and extending its flight time.

[0034] Based on the above embodiments, please refer to the appendix. Figure 5 The multiple channels, from top to bottom, include channel one, channel two, channel three, channel four, and channel five. The bottom of the stabilizing ball 401 has an opening that connects to channel five to maintain internal airflow. The outer walls of channels one and two have filter holes. A sealing piston block 414 is slidably disposed inside channel four. An elastic element two 415 is fixed between the sealing piston block 414 and channel four. A flow port 416 is opened on the side of channel four facing the sealing piston block 414. The sealing piston block 414 is held at the flow port 416 by the elastic force of the elastic element two 415 to block the flow port 416.

[0035] Specifically, after sampling, when the stabilizing ball 401 flows upward, the resistance of the water flow pushes the adjusting member 408 downward, thereby opening the opening 402. At the same time, the adjusting member 408 presses down on the sealing piston block 414, so that the sealing piston block 414 is lower than the flow port 416 and the flow port 416 is opened. When the stabilizing ball 401 rises in the water, the water flows into the channel through the filter hole, then into the stabilizing ball 401 through the flow port 416, and finally flows out through the opening 402. This reduces the resistance of the stabilizing ball 401 when it rises, making it easier to recover the stabilizing ball 401. The size of the flow port 416, the channel, and the opening 402 are adjusted according to the volume of the stabilizing ball 401 to keep the water flow in a suitable flow velocity range. No specific limitations are made in this embodiment.

[0036] Based on the above embodiments, please refer to the appendix. Figure 6 The opening 402 has a cylindrical body 417 fixed inside, which can accommodate the sealing plate 403 and is closed at the bottom. An annular filter plate 418 is sleeved on the outside of the cylindrical body 417. An elastic telescopic rod 419 is fixed on the upper surface of the filter plate 418, and the top end of the elastic telescopic rod 419 is fixedly connected to the cylindrical body 417. The elastic telescopic rod 419 includes an outer cylinder and an inner rod that are slidably connected. An elastic element is sleeved in the area of ​​the inner rod located inside the outer cylinder to keep the inner rod retracted inside the outer cylinder.

[0037] Specifically, initially, the sealing plate 403 descends into the cylinder 417 under the action of gravity to prevent water from directly acting on the bottom of the sealing plate 403 when water enters, thus pushing the sealing plate 403 upward and affecting the water intake of the opening 402. The filter plate 418 is kept in the opening 402 by the elastic force of the elastic telescopic rod 419 to filter the water entering the stabilizing ball 401 and prevent impurities in the water from entering.

[0038] As the stabilizing ball 401 rises, the water flow impact causes the filter plate 418 to fall and detach from the opening 402, thus avoiding obstruction of the water flowing out of the stabilizing ball 401 and improving the water flow efficiency.

[0039] Example 3, please refer to the appendix. Figure 7 The first take-up and release machine 5 is fixedly installed on the inner bottom wall of the mounting base 1. The top end of the suspension rope 2 is wound and fixed on the take-up drum of the first take-up and release machine 5, and the bottom end of the suspension rope 2 is fixedly connected to the stabilizing ball 401. The sampling component 3 is fixed on the surface of the suspension rope 2. The first take-up and release machine 5 can be powered independently or electrically connected to the power supply system of the UAV. The first take-up and release machine 5 adopts an intelligent meter-counting take-up and release machine to achieve accurate measurement of the release length.

[0040] Specifically, the first wire take-up and release machine 5 can take up and release the suspension rope 2, thereby flexibly adjusting the height of the stabilizing ball 401 and the sampling component 3, and adjusting the sampling depth of the sampling component 3 by the length of the released wire.

[0041] Example 4, please refer to the appendix. Figure 8 Unlike Embodiment 3, where the stabilizing ball 401 is limited by its size and subject to the impact of the water flow when used in turbulent waters, this embodiment solves the above problem by adjusting the usage method. The bottom wall of the mounting base 1 is fixed with a first take-up and release machine 5 and a second take-up and release machine 6. The top of the suspension rope 2 is wound around and fixed on the winding drum of the first take-up and release machine 5. The sampling component 3 is slidably set on the suspension rope 2. The winding rope of the second take-up and release machine 6 is fixedly connected to the sampling component 3. The second take-up and release machine 6 can also use an intelligent meter-counting take-up and release machine to achieve accurate measurement of the release length. At this time, the first take-up and release machine 5 can adjust the release length of the suspension rope 2 by manually observing the tension of the suspension rope 2, so there is no need to accurately measure the release length.

[0042] Specifically, in use, the stabilizing ball 401 is first sunk to the bottom to improve its stability, and then the suspension rope 2 is taut. At this time, the second line take-up and release machine 6 takes up and releases the line, so that the sampling component 3 moves up and down along the taut suspension rope 2, thereby improving the stability of the sampling component 3 when used in turbulent waters.

[0043] Based on the above embodiments, please refer to the appendix. Figure 5 A connecting rod 420 is fixedly installed at the bottom of the sealing plate 403, and a mudguard 421 is fixedly installed at the bottom end of the connecting rod 420 through the cylinder 417.

[0044] Specifically, during the water intake process of the stabilizing ball 401, the sealing plate 403 is at the bottom, and through the connecting rod 3 420, the mudguard 421 is driven to be lower than the opening 402, so as to avoid affecting the water passing through the opening 402.

[0045] After the stabilizing ball 401 has stored water, the sealing plate 403 drives the mud baffle 421 to rise and block the bottom of the opening 402, so as to prevent the silt and impurities at the bottom of the river from clogging the filter plate 418 when the stabilizing ball 401 sinks to the bottom.

[0046] Example 5, please refer to the appendix. Figure 9 The sampling component 3 includes a ring 301. The surface of the ring 301 has several through holes 302. The through holes 302 include a receiving cavity, a sealing cavity, and a threaded cavity distributed from top to bottom. The internal threaded cavity is connected to a sampling cylinder 303. The sampling cylinder 303 includes a cylinder 417 and a hemispherical rubber layer fixed at its bottom. The lower side of the ring 301 is rotatably connected to a protective cylinder 313. The lower surface of the protective cylinder 313 has a sampling cleaning port 314. The side wall of the sealing cavity has a liquid inlet channel communicating with the outside. The sampling cleaning port 314 adopts a threaded interface that can be connected to the connector of the flushing pipe, thereby facilitating the injection of flushing fluid.

[0047] Specifically, during sampling, water enters the through-hole 302 through the liquid inlet channel, and then enters the sampling tube 303 through the through-hole 302 for sampling. The sampling cleaning port 314 is staggered from the sampling tube 303 during use, and limits the sampling tube 303 by cooperating with the protective tube 313 to prevent the sampling tube 303 from falling off or becoming loose under the impact of water flow. After use, the protective tube 313 is rotated so that the sampling cleaning port 314 is aligned with the sampling tube 303 in sequence, making it easy for the monitoring personnel to twist and remove the sampling tube 303. After the sampling tube 303 is removed, cleaning fluid is injected through the sampling cleaning port 314 to facilitate rinsing of the protective tube 313 and the inside of the ring 301 for easy cleaning.

[0048] Based on the above embodiments, please refer to the appendix. Figure 9 - Appendix Figure 10 To facilitate multiple sampling, this embodiment proposes the following scheme: A magnetic ring 304 with a notch on its surface is provided above the ring body 301. A rotating layer 305 is fixed on the outer wall of the magnetic ring 304. The bottom end of the rotating layer 305 is rotatably connected to the ring body 301. A buoyant sealing head 306 is fitted inside the sealing cavity. A magnetic block that repels the magnetic ring 304 is fixed inside the sealing head 306. A connecting rod 308 is fixed on the upper surface of the sealing head 306. The top end of the connecting rod 308 is fixedly connected to the top wall of the receiving cavity. A driving mechanism is provided inside the ring body 301 to drive the rotating layer 305 to rotate. The spacing of the notch in the magnetic ring 304 is smaller than the spacing between the two sampling cylinders 303.

[0049] Specifically, initially, the notch of the magnetic ring 304 is misaligned with the sampling cylinder 303. Through the magnetic repulsion between the magnetic ring 304 and the magnetic block, the sealing head 306 descends stably into the sealing cavity, thereby blocking the liquid inlet channel and preventing external water from entering the sampling cylinder 303. During sampling, the driving mechanism drives the ring 301 to rotate, so that when the notch of the magnetic ring 304 rotates to the top of the unused sampling cylinder 303, the magnetic repulsion is upward, and the sealing head 306 slides upward into the receiving cavity under its own buoyancy, thereby opening the liquid inlet channel above the sampling cylinder 303 and allowing external water to flow into the sampling cylinder 303. After sampling is completed, the driving mechanism drives the ring 301 to rotate again, so that the notch stops between the used sampling cylinder 303 and the unused sampling cylinder 303, thereby closing the used sampling cylinder 303. Repeating the above steps can realize the multiple sampling function of the sampling component 3, which helps to increase the monitoring range of the water environment.

[0050] Based on the above embodiments, please refer to the appendix. Figure 10The driving mechanism includes a waterproof motor 310 fixed inside the ring 301. A gear 311 is fixed at the driving end of the waterproof motor 310. A toothed groove that meshes with the gear 311 is opened on the inner side wall of the rotating layer 305. A filter cylinder 312 is fixed on the outer side wall of the ring 301. The waterproof motor 310 uses a servo motor to precisely control the rotation position of the notch.

[0051] Specifically, the waterproof motor 310 drives the gear 311 to rotate, and the gear 311 drives the rotating layer 305 to rotate, thereby adjusting the position of the notch and automatically opening and closing the sampling cylinder 303.

[0052] Based on the above embodiments, the waterproof motor 310 can be powered and remotely operated by having a built-in power supply and wireless controller in the ring body 301. Alternatively, the winding rope of the second take-up and unwinding machine 6 can be made of photoelectric composite cable, and the waterproof motor 310 can be powered and control signals transmitted through the built-in power supply and wireless controller in the mounting base 1 or the power supply and control system of the drone.

[0053] Based on the above embodiments, please refer to the appendix. Figure 11 The bottom of the ring 301 protrudes downward to form a column 315 corresponding to the sampling and cleaning port 314. The inside of the column 315 and the ring 301 is provided with a connected mounting groove 316. A limiting head 317 made of ferromagnetic material is slidably connected inside the mounting groove 316. An L-shaped locking head 319 is fixed on one side of the bottom end of the limiting head 317. A locking hole plate 320 is inserted into the top of the locking head 319. One end of the locking hole plate 320 is fixedly connected to the inner wall of the protective cylinder 313. Indicator lines are provided on the surface of the protective cylinder 313 and the filter cylinder 312 to assist the sampling and cleaning port 314 in aligning with the column 315.

[0054] Specifically, when disassembling and assembling the sampling cylinder 303, the notch is rotated to the top of the column 315 by the drive mechanism. The limiting head 317 moves upward by the elastic force of the elastic element 3, causing the locking head 319 to exit the locking hole plate 320. At this time, the protective cylinder 313 can be rotated to disassemble and assemble the sampling cylinder 303. Before sampling, the sampling cleaning port 314 is aligned with the column 315. The drive mechanism drives the notch to rotate to the area between the column 315 and the sampling cylinder 303. At this time, the magnetic ring 304 moves to the top of the limiting head 317. The magnetic attraction between the limiting head 317 and the magnetic ring 304 drives the limiting head 317 to rise, causing the locking head 319 to insert into the locking hole plate 320, thereby locking the position of the protective cylinder 313. This achieves the effect of stabilizing and protecting the sampling cylinder 303. Furthermore, the bottom of the column 315 blocks the sampling cleaning port 314, preventing impurities in the water from entering the protective cylinder 313.

[0055] Work processes, such as Figure 1-11The diagram shown is a schematic of the device after water filling. In use, the stabilizing ball 401 is first immersed in water. Water enters the stabilizing ball 401 through the opening 402, thereby increasing its weight and improving its ability to resist water flow impact. The water flow in the stabilizing ball 401 drives the buoyancy layer 405 to rise. When it rises to the top, the sealing plate 403 moves to abut against the inner top wall of the upper chamber of the opening 402, and the snap-fit ​​structure locks the buoyancy layer 405, thereby fixing the position of the buoyancy layer 405. This causes the sealing plate 403 to block the opening 402, preventing the water entering the stabilizing ball 401 from flowing out, thus stabilizing the weight of the stabilizing ball 401 and achieving the effect of stabilizing the sampling component 3.

[0056] When the stabilizing ball 401 rises to the water surface after sampling, the adjusting component 408 drives the magnetic ring 411 to descend, causing the magnetic ring 411 to move to the magnetic ring 412. The magnetic force of the two automatically drives the locking block 406 to slide into the mounting cavity, causing the locking block 406 to exit the slot 410, thus automatically unlocking the buoyancy layer 405. This causes the sealing plate 403 to descend and open the opening 402, allowing the water in the stabilizing ball 401 to be discharged. This reduces the weight carried by the drone during subsequent flight, reduces the flight pressure of the drone, and extends the flight time.

[0057] During sampling, the notch of the magnetic ring 304 is offset from the sampling cylinder 303. Through the magnetic repulsion between the magnetic ring 304 and the magnetic block, the sealing head 306 descends stably into the sealing cavity, blocking the liquid inlet channel and preventing external water from entering the sampling cylinder 303. During sampling, the drive mechanism rotates the ring 301, causing the notch of the magnetic ring 304 to rotate upwards until it reaches above an unused sampling cylinder 303. The magnetic repulsion then causes the sealing head 306 to slide upwards into the receiving cavity under its own buoyancy, opening the liquid inlet channel above the sampling cylinder 303 and allowing external water to enter. After sampling, the drive mechanism rotates the ring 301 again, causing the notch to remain between the used and unused sampling cylinders 303, thus closing the used sampling cylinder 303. Repeating these steps allows for multiple sampling operations by the sampling component 3, helping to increase the monitoring range of the water environment. When in use, the sampling cleaning port 314 is offset from the sampling tube 303 and, through cooperation with the protective tube 313, limits the sampling tube 303 to prevent it from falling off or becoming loose under the impact of water flow. After use, the protective tube 313 is rotated so that the sampling cleaning port 314 is aligned with the sampling tube 303 in sequence, making it easy for monitoring personnel to twist and remove the sampling tube 303. After the sampling tube 303 is removed, cleaning fluid is injected through the sampling cleaning port 314 to facilitate rinsing of the protective tube 313 and the inside of the ring 301 for easy cleaning.
