The terms used herein in the specification of this application are only for the purpose of describing specific implementation methods and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0023] like Figures 1 to 3 As shown, the present application provides a water sampling device based on a floating boat, including a hull 1, a sampling mechanism 2, an anti-winding mechanism 4 and a power supply mechanism 3, wherein a through hole is opened at the bottom of the hull 1; the sampling mechanism 2 is arranged on the hull 1 and extends into the water through the through hole for collecting water samples; the anti-winding mechanism 4 includes a protective sleeve 44, a plurality of rotating blades 43 and a driving assembly 41, the protective sleeve 44 surrounds the sampling mechanism 2 and extends underwater through the through hole, the protective sleeve 44 is connected with the hull 1, the rotating blades 43 are installed on the underwater part of the protective sleeve 44 to form an umbrella-shaped protective structure, the underwater end of the sampling mechanism 2 is located within the protection range of the rotating blades 43, the driving assembly 41 is located in the hull 1, and is driven and connected to the protective sleeve 44; the power supply mechanism 3 is arranged in the hull 1, and is electrically connected to the sampling mechanism 2, the anti-winding mechanism 4 and the hull 1.

[0024] Specifically, a through hole is provided at the bottom of the hull 1, and the water inlet end of the sampling mechanism 2 passes through the through hole and goes deep into the water. The main part of the sampling mechanism 2 is fixed at an appropriate position of the hull 1, and is realized by bolts, buckles or other fasteners to ensure that the sampling mechanism 2 is stable and adjustable. The hull 1 provides a stable platform, so that the sampling mechanism 2 can accurately perform sampling tasks in different waters. At the same time, the mobility of the hull 1 makes the selection of sampling locations more flexible. The protective sleeve 44 is a key part of the anti-entanglement mechanism 4, which surrounds the sampling mechanism 2 and cooperates with the through hole at the bottom of the hull 1 to extend underwater. The connection between the protective sleeve 44 and the hull 1 needs to ensure sufficient sealing to prevent water from penetrating into the interior of the hull 1. The protective sleeve 44 and the sampling mechanism 2 are also sealed to ensure that water cannot penetrate into the hull 1. The rotating blade 43 is installed in the underwater part of the protective sleeve 44 and is fixed by welding, threading or other connection methods to form an umbrella-shaped structure. The combination of the protective sleeve 44 and the hull 1 and the installation of the rotating blades 43 together constitute an effective anti-entanglement system. The drive assembly 41 is connected to the protective sleeve 44. When the drive assembly 41 is started, the rotating blades 43 start to rotate to remove the surrounding debris and protect the sampling mechanism 2 from entanglement. The power supply mechanism 3 is arranged on the hull 1, and the specific position depends on the design requirements and space layout. The power supply mechanism 3 is connected to various electrical devices in the hull 1 (such as the sampling mechanism 2, the driving assembly 41 of the anti-entanglement mechanism 4) through wires or cables. These lines are carefully laid out to avoid interfering with the structural integrity of the hull 1. The power supply mechanism 3 is the energy source of the entire device. It provides the necessary power to the sampling mechanism 2 and the anti-entanglement mechanism 4 through the power line to ensure that these components can operate normally. The sampling mechanism 2 and the anti-entanglement mechanism 4 are independent of each other in terms of function and each has a specific task, but they are indirectly connected through the same common protective sleeve 44. The protective sleeve 44 surrounds the sampling mechanism 2. The sealing design between the two is extremely important and can effectively prevent the external water from penetrating into the hull 1. Sealing is not only related to the normal operation of the equipment, but also a basic condition for ensuring the safety of the hull 1, avoiding the reduction of stability or potential sinking risk caused by water penetration. In addition, the protective sleeve 44 is also integrated with the rotating blade 43 to enhance the anti-entanglement effect.

[0025] The working process is as follows:

[0026] The hull 1 is moored in the predetermined sampling waters, the sampling mechanism 2 is started, and water samples are collected. The water collection part of the sampling mechanism 2 is tightly matched with the protective sleeve 44 to ensure sealing and prevent water from entering the hull 1. At the same time, the rotating blade 43 is started by the drive assembly 41 connected to the protective sleeve 44, and starts to rotate, forming a dynamic protective cover, which effectively prevents debris in the water from entangled with the sampling mechanism 2. Under the protection of the anti-entanglement mechanism 4, the sampling mechanism 2 smoothly reaches the specified depth and performs water quality collection. During this process, the power supply mechanism 3 continues to provide power support for the sampling mechanism 2 and the anti-entanglement system. After the sampling is completed, the sampling mechanism 2 and the drive assembly 41 are turned off, and the rotating blade 43 stops rotating. The water sample is collected for subsequent analysis. After the operation is completed, the sampling mechanism 2, the anti-entanglement mechanism 4 and all related components are inspected and maintained to ensure their performance is intact and ready for the next mission.

[0027] The above technical solution adopted by the water sampling device based on a floating vessel provided in the present application can achieve the following beneficial effects:

[0028] The present application is provided with a protective sleeve 44, a plurality of rotating blades 43 and a driving assembly 41. The protective sleeve 44 surrounds the sampling mechanism 2, extends underwater through the through hole, and is connected with the hull 1, and can rotate freely around the sampling mechanism 2; a plurality of rotating blades 43 are distributed in the underwater part of the protective sleeve 44, together forming an umbrella-shaped protective barrier; the driving assembly 41 drives the protective sleeve 44 to rotate, thereby driving the rotating blades 43 to rotate at high speed, thereby generating a strong water flow disturbance, which can effectively disperse the phytoplankton, branches, plastic fragments and other debris around the sampling point, greatly reduce the impact of these obstacles on the sampling process, avoid blockage or entanglement, and ensure the smooth operation of the sampling action. In addition, the high-speed rotating blades 43 also have a deterrent effect, which can effectively prevent large fish from approaching, further ensure the physical safety of the sampling mechanism 2, and protect it from damage caused by accidental collisions.

[0029] In one embodiment, a groove is formed on the inner wall of the through hole, and a waterproof bearing 441 is sleeved on the outer wall of the protective sleeve 44 , and the waterproof bearing 441 is fixed in the groove.

[0030] Specifically, in order to ensure the stability of the protective sleeve 44 and the waterproofness between the hull 1, an annular groove is opened on the inner wall of the preset through hole of the hull 1, and the outer wall of the protective sleeve 44 is provided with a waterproof bearing 441 to cooperate with the groove, and the outer ring of the waterproof bearing 441 is fixed in the groove. The waterproof bearing 441 has been carefully designed, and its size and shape can perfectly match the groove on the inner wall of the through hole, so as to achieve good sealing performance. After consideration in material selection and design, the waterproof bearing 441 with the publication number CN214404344U is adopted. The precise matching of the groove and the waterproof bearing 441 not only provides the necessary support for the protective sleeve 44 physically, ensuring its stable position during rotation, but also limits the movement in unexpected directions through precise positioning function, greatly enhancing the stability and reliability of the entire structure. The waterproof bearing 441, by virtue of its close fit with the groove, effectively prevents water penetration while ensuring free rotation, and protects the interior of the hull 1 from water intrusion.

[0031] In a preferred embodiment, at least three rotating blades 43 are provided.

[0032] Specifically, at least three rotating blades 43 are provided to provide better stability. Compared with a design with two blades, three blades or more can distribute the resistance of airflow or water flow more evenly, reduce vibration and noise, and improve efficiency. This is because multiple blades can push air or water more continuously, reducing energy waste. Increasing the number of blades helps to balance the load during rotation. This reduces the stress on the central axis, extends the service life of the equipment, and reduces maintenance costs. In some cases, increasing the number of blades can improve safety. For example, if one blade is damaged or fails, the other blades can still maintain basic functions, reducing the risk of failure. The surface of each rotating blade 43 is set to a smooth curved surface, and the smooth surface can reduce the attachment tendency of organisms such as phytoplankton (including cyanobacteria, green algae, etc.), because the smooth surface reduces the initial point of biological attachment, making it difficult for organisms to adhere to it. When the sampling mechanism 2 moves in the water, the water flow will help remove substances that attempt to attach to the smooth surface, thereby keeping the rotating blade 43 clean and running efficiently. At the same time, the smooth curved surface can reduce the chance of entanglement of foreign objects such as branches and plastic fragments. When these objects contact the rotating blades 43, they are more likely to slide off rather than get stuck, reducing the risk of clogging. In the water flow, the smooth surface helps objects to be carried away by the water flow faster rather than gathering around the rotating blades 43.

[0033] Based on the above embodiment, the three rotating blades 43 are arranged in a circular array on the outer wall of the protective sleeve 44 .

[0034] Specifically, the three rotating blades 43 are distributed in a circular array along the circumferential direction of the protective sleeve 44, that is, the angle between each rotating blade 43 and the adjacent rotating blade 43 is equal. This equidistant distribution can ensure that the load of the rotating blade 43 on the central axis is evenly distributed when it rotates, thereby reducing vibration and noise caused by unbalanced load, improving the stability of the equipment, extending the service life of the equipment, and also helping to reduce water resistance.

[0035] In one embodiment, the driving assembly 41 includes a motor 413, a gear 411 and a rotating shaft 412, wherein the output end of the motor 413 is connected to one end of the rotating shaft 412, and the end of the rotating shaft 412 away from the motor 413 is connected to the gear 411, and the gear 411 is meshed with the protective sleeve 44.

[0036] Specifically, the drive assembly 41 includes a motor 413, a rotating shaft 412 and a gear 411. The output end of the motor 413 is firmly connected to one end of the rotating shaft 412 through a keyway, a spline or a coupling, so as to ensure lossless transmission of power. The other end of the rotating shaft 412 is tightly connected to the gear 411 through a key, a bolt or other fasteners to ensure that the two can rotate synchronously. The gear 411 and the gear 411 outside the protective sleeve 44 are matched through precise tooth shapes to achieve smooth transmission of power, while protecting the internal sampling mechanism 2 from external interference.

[0037] In one embodiment, the sampling mechanism 2 includes a collecting container 21, a pipette 23 and a water pump 22. The collecting container 21 is arranged in the hull 1, the water outlet end of the pipette 23 is connected to the collecting container 21, the water inlet end of the pipette 23 passes through the protective sleeve 44 and penetrates into the water, the water pump 22 is connected to the pipette 23, and the power input end of the water pump 22 is connected to the power supply mechanism 3.

[0038] Specifically, the sampling mechanism 2 mainly includes a collection container 21, a pipette 23 and a water pump 22. The whole process is powered by a power supply mechanism 3 to ensure the normal operation of the pumping device. The collection container 21 is placed on the hull 1 as the main container for collecting and temporarily storing the extracted samples. It is usually designed to have a large enough capacity to meet different sampling needs. One end of the pipette 23 goes deep into the target water area and is guided to the water body to be tested through the protective sleeve 44, and the other end is connected to the collection container 21. The pipette 23 should have good corrosion resistance and flexibility to adapt to sampling operations at different depths and environmental conditions. The water pump 22, as the power source in the sampling process, is responsible for sucking the liquid sample in the target water area into the collection container 21 through the pipette 23. The connection between the water pump 22 and the pipette 23 should be well sealed to prevent leakage during the suction process. After the water pump 22 is started, a negative pressure is generated, and the liquid sample in the target area is sucked in through the pipette 23, and then transported along the pipeline to the collection container 21 located inside the hull 1.

[0039] In one embodiment, a sealing ring is provided between the outer wall of the pipette 23 and the inner wall of the protective sleeve 44 , and the sealing ring is fixedly connected to the pipette 23 and movably connected to the protective sleeve 44 .

[0040] Specifically, the sealing ring is a common sealing element, generally made of rubber, silicone or other elastic materials, and its function is to form a sealed state between the protective sleeve 44 and the pipette 23 to prevent water from penetrating into the hull 1 from the space between the two. The sealing ring is placed in the gap between the outer wall of the pipette 23 and the inner wall of the protective sleeve 44. The sealing ring is directly attached or fixed to the pipette 23 by other means to ensure that it is in a predetermined position of the pipette 23 and will not fall off or shift, thereby continuing to play a sealing role. In addition, a certain relative movement is allowed between the sealing ring and the protective sleeve 44. This movable connection can be achieved by the elastic deformation of the sealing ring itself, or by designing a specific sliding structure or reserving a corresponding space.

[0041] In a preferred embodiment, a filter 24 is provided at the water inlet of the liquid suction tube 23 .

[0042] Specifically, in the sampling mechanism 2, a filter 24 is provided at the water inlet of the pipette 23. The filter 24 can be a cylindrical tube, a conical tube, etc. One end of the filter 24 is connected to the water inlet of the pipette 23, and the end away from the pipette 23 is closed, and a plurality of water inlet holes are provided on the cylinder. The filter 24 is usually made of corrosion-resistant materials, such as stainless steel or special plastics, and is filled with filter media, such as metal mesh, fiber cloth or activated carbon, to intercept and capture solid particles, suspended matter or larger organisms in the water. The filter 24 can effectively intercept suspended matter, sediment, algae, etc. in the water, prevent these impurities from clogging the pipette 23, and ensure the smooth progress of the sampling process.

[0043] Based on the above embodiment, a scraper 42 is provided on the rotating blade 43 , and the scraper 42 is in contact with the filter element 24 .

[0044] Specifically, in the sampling mechanism 2, in order to keep the filter 24 clean and efficient, a scraper 42 is provided on the rotating blade 43 so that it contacts the outer surface of the filter 24, thereby solving the problem that the filter 24 is prone to accumulate impurities after long-term operation, and ensuring the continuity and accuracy of the sampling process. The scraper 42 is usually made of a material with a certain elasticity, such as wear-resistant rubber or special plastic, and its shape is designed to fit closely with the outer surface of the filter 24. When the rotating blade 43 drives the scraper 42 to rotate, the edge of the scraper 42 can effectively scrape off dirt, algae, suspended matter and other impurities attached to the surface of the filter 24, preventing these impurities from clogging the pores of the filter 24, affecting the filtering effect and the smooth flow of the pipette 23. The rotation of the rotating blade 43 directly drives the scraper 42 to move, without the need for an additional power source, simplifying the system structure and reducing energy consumption. As the rotating blade 43 continues to rotate, the scraper 42 continuously contacts the surface of the filter 24, achieving an immediate cleaning effect and avoiding the accumulation of impurities.

[0045] In one embodiment, the power supply mechanism 3 includes a storage chamber 34, a battery 31, a solar panel 32 and a solar charge controller 33. The storage chamber 34 is located in the floating boat. The battery 31 and the solar charge controller 33 are both located in the storage chamber 34. The solar panel 32 is arranged on the top of the outer side of the storage chamber 34. The battery 31, the solar panel 32 and the solar charge controller 33 are connected to each other through a connecting line. The battery 31 and the solar panel 32 are respectively connected to the solar charge controller 33 through a connecting line.

[0046] Specifically, the power supply mechanism 3 is designed with a hybrid power supply system for the water sampling equipment, which mainly includes a storage chamber 34, a battery 31, a solar panel 32 and a solar charging controller 33, with the purpose of providing a stable and sustainable power supply to support the long-term operation of the equipment. The storage chamber 34 is located on the hull 1 and is a space for installing and protecting the core components of the power supply system. The battery 31 is installed therein to store the electric energy converted by the solar panel 32, which can power the sampling equipment at night or on cloudy days to ensure uninterrupted operation of the system. The solar panel 32 is installed on the outer top of the storage chamber 34, directly exposed to the sun, responsible for capturing solar energy and converting it into electric energy. There are two solar panels 32 installed and symmetrically distributed, and two support rods are provided at the lower end of each solar panel 32 to enhance the structural stability. The contact parts of the upper ends of the two solar panels 32 are connected with a water retaining plate, and a bracket is welded at the lower end of the water retaining plate, and the side of the lower end of the bracket is in contact with the solar panel 32. The water retaining plate can block rainwater, prevent water accumulation at the battery 31, and avoid leakage damage to the device. The solar charge controller 33 is also located in the storage chamber 34, and is used to monitor and manage the charging process of the solar panel 32 to the battery 31, to prevent overcharging or over-discharging, and to ensure the health of the battery 31. Under lighting conditions, the solar panel 32 converts light energy into DC power and transmits it to the solar charge controller 33 through a connecting line. After receiving the power, the solar charge controller 33 monitors the battery status and intelligently adjusts the charging current to ensure that the battery 31 is charged safely and efficiently. During the day, the excess power generated by the solar panel 32 will be stored in the battery 31; at night or on cloudy days, the battery 31 releases power, thus forming a closed-loop energy supply system.

[0047] Using solar energy as the main energy source is in line with the development trend of green and low-carbon development, and reduces dependence on traditional fossil fuels. Although the initial investment is high, the long-term use of solar panels 32 and batteries 31 can reduce operation and maintenance costs, and is particularly suitable for sampling operations in remote waters. The combination of solar panels 32 and batteries 31 ensures all-weather power supply, improves the stability and reliability of the sampling equipment, and the maintenance of the two is relatively simple, reducing the need for on-site maintenance, reducing overall operating costs, and making the device last longer.

[0048] The specific working process of this application is as follows:

[0049] The hull 1 is accurately moored at the pre-selected sampling waters, and the motor 413, gear 411, protective sleeve 44, rotating blade 43, scraper 42, filter 24, water pump 22 and power supply mechanism 3 are comprehensively inspected to ensure that all components are in good working condition. The power is turned on, the motor 413 starts, and the gear 411 is driven to rotate through the rotating shaft 412. The rotation of the gear 411 drives the protective sleeve 44 to rotate, and then the rotating blade 43 fixed thereon starts to rotate, forming a dynamic protection. The scraper 42 on the rotating blade 43 rotates accordingly, continuously cleaning the outer wall of the filter 24 to prevent impurities from accumulating. Under the coordinated action of the motor 413, gear 411, protective sleeve 44 and rotating blade 43, the water pump 22 is started to start collecting water samples. The water pump 22 sucks the water sample from the filter 24, and after preliminary filtration to ensure the purity of the sample, it is then transported to the sample collection container 21 inside the hull 1. After the sampling is completed, the water pump 22 and the motor 413 are turned off in turn, and the movement of the rotating blades 43 and the scraper 42 is stopped. The collected water samples are properly stored and prepared for subsequent laboratory analysis. After the operation is completed, the sampling mechanism 2, the anti-winding system and all its components are fully inspected, and cleaned and repaired when necessary to ensure that the equipment is in the best condition at all times and is fully prepared for the next sampling task. During the entire sampling process, the power supply mechanism 3 continuously provides stable power support to the motor 413, the water pump 22 and other electrical components to ensure efficient operation of the system.
