Technical Field

[0001] This utility model relates to the field of water quality monitoring technology, specifically a water quality sampling device for monitoring the health of rivers and lakes based on benthic biodiversity. Background Technology

[0002] With the acceleration of industrialization and urbanization, human activities have had an increasingly significant impact on the natural environment, with river and lake ecosystems being particularly disturbed. Benthic organisms, as an important component of river and lake ecosystems, provide a direct reflection of the ecosystem's health status through their community structure and diversity. By monitoring and analyzing benthic biodiversity, it is possible to accurately assess water quality changes, ecosystem stability, and the extent of human impact on the river and lake environment.

[0003] Water quality is a key factor affecting the survival and reproduction of benthic organisms, and accurate water sampling is fundamental for scientific monitoring and analysis. Currently, water sampling faces numerous challenges and problems in river and lake health monitoring based on benthic biodiversity. Traditional water sampling devices are often designed to collect only a single water quality parameter, making it difficult to meet the need to simultaneously acquire multiple water quality indicators and parameters related to the benthic organism's living environment. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a water quality sampling device for river and lake health monitoring based on benthic biodiversity, which solves the technical problem of single sampling in existing water quality sampling devices.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a water quality sampling device for monitoring river and lake health based on benthic biodiversity, comprising an underwater robot and an installation shaft fixed to the bottom of the underwater robot, a fixed plate fixed to the bottom of the installation shaft, a sampling slot on the fixed plate, a movable plate rotatably connected to the installation shaft below the fixed plate, a rotation drive mechanism connected to the movable plate at the bottom of the fixed plate, and a plurality of holes on the movable plate, with a storage mechanism placed in the holes;

[0006] The storage mechanism includes a sampling tube located inside the disk hole, an energy storage component fixed inside the sampling tube, a sealing cap connected to the top of the energy storage component, the sealing cap fitting inside the opening of the sampling tube, and a beveled protrusion on the surface of the sealing cap that slides against the bottom surface of the fixed disk.

[0007] Preferably, the energy storage component includes a fixed frame fixed inside the sampling tube, a guide rod sleeved on the fixed frame, the top of the guide rod being fixedly connected to the sealing cover, and a spring sleeved on the guide rod between the fixed frame and the sealing cover.

[0008] Preferably, the rotary drive mechanism includes a motor mounted on a fixed disk, a gear fixed on the output shaft of the motor, a gear ring meshing on one side of the gear, and the gear ring being fixed to a movable disk.

[0009] Preferably, the sampling tube has a mesh structure at its opening.

[0010] Preferably, a buckle is fixedly provided on the outer wall of the pipe opening, and a fixing buckle that engages with the buckle is rotatably connected to the surface of the movable disc.

[0011] Preferably, a positioning block is fixed at the bottom of the pipe opening, and the positioning block is inserted into a positioning hole opened on the surface of the movable disc.

[0012] By employing the above technical solution, this utility model provides a water quality sampling device for river and lake health monitoring based on benthic biodiversity, which has at least the following beneficial effects:

[0013] 1. This water quality sampling device for monitoring river and lake health based on benthic biodiversity, through the setting of a storage mechanism, allows for sampling from different areas or depths by setting up multiple sampling tubes on the moving plate. This enables sample diversity and meets the need to simultaneously obtain multiple water quality indicators and parameters related to the living environment of benthic organisms.

[0014] 2. This water quality sampling device for monitoring river and lake health based on benthic biodiversity has a beveled protrusion on the surface of the sealing cover, which slides against the bottom of the fixed plate. When the moving plate rotates the sampling tube, the bottom of the fixed plate presses down on the protrusion, thus sealing the sample tightly and preventing it from being contaminated.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] As research into river and lake ecosystems deepens, the demand for intelligent and automated water sampling devices is increasing. Traditional manual sampling methods are inefficient and labor-intensive, making it difficult to meet the needs of long-term, continuous, and high-frequency monitoring. Moreover, in some remote or harsh river and lake areas, manual sampling poses safety hazards and cannot obtain accurate water quality data in a timely manner.

[0026] Due to the limitations of existing technologies in terms of single-sampling methods, please refer to... Figures 1-5This embodiment provides a water quality sampling device for river and lake health monitoring based on benthic biodiversity. Each sampling tube 601 can sample from different areas or depths, achieving sample diversity and meeting the need to simultaneously obtain multiple water quality indicators and parameters related to the benthic organism's living environment. The device includes an underwater robot 1 and a mounting shaft 2 fixed to the bottom of the underwater robot 1. A fixed disk 3 is fixed to the bottom of the mounting shaft 2, and a sampling slot 301 is provided on the fixed disk 3. A movable disk 5 is rotatably connected to the mounting shaft 2 below the fixed disk 3. A rotary drive mechanism 4 connected to the movable disk 5 is provided at the bottom of the fixed disk 3. Multiple disk holes are opened on the movable disk 5, and storage mechanisms 6 are placed in the disk holes. In use, the underwater robot 1 can drive the entire sampling device to perform sampling work in different areas or depths underwater. During sampling, the rotary drive mechanism 4 drives the movable disk 5 to rotate, so that each storage mechanism 6 on the movable disk 5 can sample separately.

[0027] Regarding the automatic opening and closing of the sealing cap 603 during sampling, please refer to... Figure 4 and Figure 5 The storage mechanism 6 includes a sampling tube 601 located within a disk opening. An energy storage component 602 is fixed inside the sampling tube 601. A sealing cap 603 is connected to the top of the energy storage component 602. The sealing cap 603 fits into the opening 6011 of the sampling tube 601. The surface of the sealing cap 603 has a beveled protrusion 604, which slides against the bottom surface of the fixed disk 3. When the rotation drive mechanism 4 rotates the sampling tube 601 to the sampling slot 301, the fixed disk 3 releases its downward pressure on the sealing cap 603. Under the action of the energy storage component 602, the sealing cap 603 is pushed upwards, allowing external water to enter the sampling tube 601 to complete the sampling process. After sampling, the movable disk 5 can continue to rotate the sampling tube 601. When the protrusion 604 is rotated, it contacts the bottom of the fixed plate 3 again. The fixed plate 3 then presses down on the sealing cover 603 through the protrusion 604, thereby sealing the sampling tube 601. Furthermore, the energy storage component 602 includes a fixed frame 6021 fixed inside the sampling tube 601. A guide rod 6022 is sleeved on the fixed frame 6021. The top of the guide rod 6022 is fixed to the sealing cover 603. A spring 6023 is sleeved on the guide rod 6022 between the fixed frame 6021 and the sealing cover 603. When the sampling tube 601 is in the sampling slot 301, the sealing cover 603 can be pushed upward by the elastic force of the spring 6023 to open the sampling tube 601 and perform sampling.

[0028] When performing batch sampling, it is necessary to control the rotation of the movable disk 5. For this purpose, please refer to... Figure 3 and Figure 4The rotary drive mechanism 4 includes a motor 401 mounted on a fixed disk 3. A gear 402 is fixed on the output shaft of the motor 401. A gear ring 403 meshes with one side of the gear 402. The gear ring 403 is fixed to the movable disk 5. The motor 401 works and drives the gear 402 to rotate. The gear 402 drives the movable disk 5 to rotate by meshing with the gear ring 403.

[0029] Furthermore, when the sealing cap 603 is opened, impurities in the water will also enter the sampling tube 601, thus affecting the sampling quality. To address this issue, the opening 6011 of the sampling tube 601 is designed with a mesh structure. When the sealing cap 603 is moved upwards and opened, the sampled water will enter the sampling tube 601 through the opening 6011. Since the opening 6011 has a mesh structure, it can intercept impurities, preventing them from entering the sampling tube 601. This has the advantages of filtration and improved sampling quality.

[0030] Since the sampling tube 601 is directly inserted into the hole of the movable disk 5, the sampling tube 601 itself lacks fixation and is prone to detaching from the movable disk 5 and falling off. To address this issue, a buckle 605 is fixedly provided on the outer wall of the tube opening 6011, and a fixing buckle 606 that engages with the buckle 605 is rotatably connected to the surface of the movable disk 5. After the sampling tube 601 is placed, the fixing buckle 606 is rotated to tighten the buckle 605, thereby fixing the sampling tube 601 and ensuring that the sampling tube 601 can take samples smoothly.

[0031] Furthermore, a positioning block 607 is fixedly provided at the bottom of the tube opening 6011. The positioning block 607 is inserted into the positioning hole opened on the surface of the movable disk 5. Through the cooperation of the positioning block 607 and the positioning hole, the sampling tube 601 is placed in the same position each time. In this way, the protrusion 604 on the sealing cover 603 faces the same direction, ensuring that the protrusion 604 can be smoothly pressed down by the fixed disk 3 after the movable disk 5 is rotated.

[0032] It should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
