Description

Technical Field

[0001] The utility model relates to the field of water sampling, in particular to a small water body sampling device. Background Art

[0002] Among the various tasks of environmental protection, environmental monitoring is a crucial link. By continuously observing and analyzing various indicators in the environment, such as air, soil, water quality, etc., people can understand the current situation and changing trends of the environment, and then take corresponding protection measures. Among these monitoring tasks, water quality monitoring is particularly important, after all, water is the basis for the survival of organisms on the earth. Water quality sampling is a key link in water quality monitoring work. Accurately extracting water samples at specific time and space positions is crucial for subsequent water quality analysis work. Therefore, when conducting water quality sampling, professional sampling equipment is required. These devices can help people quickly extract water samples from various water bodies, such as rivers, lakes, oceans, groundwater, etc. At the same time, the sampling equipment also needs to have good sealing performance and representativeness to ensure that the water samples taken can truly reflect the water quality conditions at that time and space position.

[0003] Currently, the equipment we use in real life has a significant defect due to its design and technical capabilities: it cannot perform multiple samplings at multiple locations in a vast water area at one time. This means that in actual operation, we need to move the equipment multiple times, reposition it, and conduct sampling. This process is not only cumbersome but also greatly increases the time cost of sampling in different regions. This not only affects our work efficiency but also, in some cases, may even lead to data distortion or the inability to obtain key information due to time delays. Content of the Utility Model

[0004] The utility model provides a small water body sampling device, which solves the problem of taking water samples from multiple water areas.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is: a small water body sampling device, including a hull. At least two turbine cavity cylinders arranged side by side are provided at the bottom end of the hull. The rear ends of each turbine cavity cylinder are open and are provided with rotatable drainage turbines. A cavity structure is provided inside the hull. A partition plate is provided in the cavity structure. A rotatable loading mechanism and a sampling mechanism are respectively provided on both sides of the partition plate. The loading mechanism includes a placement turntable. A plurality of placement cavities are provided along the circumferential direction of the placement turntable. The placement cavities are used for placing specimen storage tubes. The sampling mechanism includes a sampling tube reel. A hollow sampling tube is wound on the sampling tube reel. The sampling tube can be curled. One end of the sampling tube is provided with a drain pipe head, and the drain pipe head faces the loading mechanism. An openable weighted cover is provided at the lower end of the hull. The other end of the sampling tube is connected to the weighted cover.

[0006] The hull material can be a material with a density less than that of water. The drainage turbine protrudes downward from the hull, enabling the weighted cover to be above the water surface. When the weighted cover is opened, water will not enter the hull.

[0007] The chambers on both sides of the partition plate are separated, and the water droplets adhering to the outer wall of the sampling tube are restricted to the chamber where the sampling mechanism is located, preventing the filling mechanism from being wetted.

[0008] A sealed cavity is provided inside the hull. An electronic control board, a battery pack, and a wireless module are provided in the sealed cavity. The electronic control board and the battery pack are connected to each electrical component. A signal receiving device is provided at the upper end of the hull, and the signal receiving device is electrically connected to the wireless module. A camera is provided at the front end of the hull, and a positioning and monitoring device is also provided on the hull. The hull can be remotely controlled by a remote controller on the shore for observation, movement, and sampling.

The lower end of the drainage hole is communicated with the inside of the turbine chamber cylinder, and the drain pipe head is telescopic to switch the alignment to the drainage hole or the placement chamber.

[0010] In a preferred solution, the filling mechanism further includes a driving device. The driving device includes a worm gear sleeved on the lower end of the placement turntable and a worm meshing with the worm gear. One end of the worm is provided with a first driving motor.

[0011] The sampling tube reel is connected inside the hull through a bracket. Similarly, one end of the sampling tube reel is driven by a second driving motor.

[0012] In a preferred solution, a placement base is provided inside the placement chamber. A spring is provided at the lower end of the placement base. The two ends of the spring respectively abut against the placement base and the bottom end of the placement chamber. A rubber damping plate is provided at the orifice of the placement chamber. A through hole is provided at the center of the rubber damping plate, and a plurality of cut grooves are provided along the circumference.

[0013] The cut grooves divide the rubber damping plate into multiple petals and endow it with certain deformation and resilience capabilities. After the sample storage tube is inserted, its lower end contacts the placement base, and the outer wall of its upper end contacts the rubber damping plate. When the sampling ship fluctuates, it can play a certain buffering role for the sample storage tube to prevent the internal liquid from spilling out.

[0014] In a preferred solution, an openable sealing cover is provided above the filling mechanism at the upper end of the hull. An annular pressure tube part is provided at the lower end of the sealing cover. A sunken notch is provided at one end of the pressure tube part, and the sunken notch faces the drain pipe head. A limiting part is provided on the outer wall of the pressure tube part, and the upper end of the limiting part abuts against the lower end face of the upper side plate of the hull.

[0015] The sunken notch has an avoidance function, enabling the drain pipe head to extend into the center of the pressure tube part to drain water to the drainage hole or the placement chamber.

[0016] In a preferred embodiment, a third driving motor is further provided at one end of each turbine chamber cylinder inside the hull. A rotatable turbine rod is provided inside the turbine chamber cylinder. One end of the turbine rod is connected to the drainage turbine, and the other end of the turbine rod is rotatably sleeved with the inner bottom end of the turbine chamber cylinder and passes through the inner bottom end of the turbine chamber cylinder to be connected to the third driving motor.

[0017] The first driving motor, the second driving motor, and the third driving motor can adopt servo motors or stepper motors.

[0018] The third driving motor is inside the cavity at the bottom of the hull and will not get water. A hollow cage is also provided near the drainage turbine inside the turbine chamber cylinder. The outer side of the cage abuts against the inner wall of the turbine chamber cylinder, and the center of the cage is rotatably connected to the turbine rod. The hollow structure enables the cage not to block the water flow but can prevent the turbine rod from cantilever rotation.

[0019] The drainage hole is communicated with the inside of the turbine chamber cylinder through a one-way valve to prevent the water flow from flowing back into the hull.

[0020] The beneficial effects of the present utility model are as follows: It is equipped with multiple sampling tubes. Through the rotation and switching of the placement turntable, and in cooperation with the pumping equipment, rapid sampling of multiple water areas can be achieved in a single voyage; the sampling tubes can also be used as suspension ropes. In cooperation with the weighted cover and the sampling tube reel, sampling at any depth can be realized; the setting of the downwardly convex turbine chamber cylinder and the upwardly concave cavity raises the bottom opening, which can prevent water from entering the bottom when the weighted cover is opened; the peristaltic pump drives the pumping of liquid from the outside, avoiding direct contact, and a drainage hole is provided to facilitate the operation of flushing the tube and prevent cross-contamination of samples from different water areas.

[0037] The chambers on both sides of the partition plate 2 are separated, and the water droplets adhering to the outer wall of the sampling tube 19 are restricted to the chamber where the sampling mechanism 4 is located, preventing the loading mechanism 3 from being wetted.

[0039] In a preferred solution, at least two turbine chamber cylinders 8 arranged side by side are provided at the bottom end of the hull 1. The rear end of each turbine chamber cylinder 8 is open and is provided with a rotatable drainage turbine 9. One end of each turbine chamber cylinder 8 inside the hull 1 is also provided with a third driving motor 803. A rotatable turbine rotating rod 801 is provided inside the turbine chamber cylinder 8.

[0040] The third driving motor 803 is inside the cavity at the bottom of the hull 1 and will not be flooded. A hollow cage 802 is also provided near the drainage turbine 9 inside the turbine chamber cylinder 8. The outer side of the cage 802 abuts against the inner wall of the turbine chamber cylinder 8, and the center of the cage 802 is rotatably connected to the turbine rotating rod 801.

[0042] The two third driving motors 803 can independently control the rotation speed. When they rotate at the same speed, the hull 1 moves straight forward. When there is a speed difference, the turning function is realized.

[0043] In a preferred solution, the loading mechanism 3 further includes a driving device 302. The driving device 302 includes a worm gear sleeved at the lower end of the placing turntable 301 and a worm meshing with the worm gear. One end of the worm is provided with a first driving motor 307.

[0044] The sampling tube reel 402 is connected inside the hull 1 through a bracket. Similarly, one end of the sampling tube reel 402 is driven by a second driving motor 401.

[0046] In a preferred solution, a placement base 305 is provided in the placement cavity 303. A spring 304 is provided at the lower end of the placement base 305. The two ends of the spring 304 respectively abut against the placement base 305 and the bottom end of the placement cavity 303. A rubber damping plate 15 is provided at the orifice of the placement cavity 303. A through-hole is provided in the center of the rubber damping plate 15, and a plurality of cut grooves are provided along the circumferential direction.

[0047] The cut grooves divide the rubber damping plate 15 into a plurality of petals and endow it with certain deformation and resilience capabilities. After the sample storage tube 18 is inserted, its lower end contacts the placement base 305, and the outer wall of its upper end contacts the rubber damping plate 15. When the sampling ship sways, it can play a certain buffering role for the sample storage tube 18 to prevent the internal liquid from spilling out.

[0048] Above the loading mechanism 3 at the upper end of the hull 1, there is an openable sealing cover 5. A ring-shaped pipe pressing part 6 is provided at the lower end of the sealing cover 5. A sunken notch 7 is provided at one end of the pipe pressing part 6, and the sunken notch 7 faces the drain pipe head 404. A limiting part 16 is provided on the outer wall of the pipe pressing part 6, and the upper end of the limiting part 16 abuts against the lower end face of the upper side plate of the hull 1.

[0049] The sunken notch 7 has an avoidance function, which enables the drain pipe head 404 to extend into the center of the pipe pressing part 6 to drain water to the drain hole 306 or the placement cavity 303.

[0050] In a preferred solution, a drain hole 306 is provided at the center of the placement turntable 301. The lower end of the drain hole 306 is communicated with the inside of the turbine cavity cylinder 8. The drain pipe head 404 is telescopic to switch the alignment with the drain hole 306 or the placement cavity 303.

[0051] In a preferred solution, a hollow fixed pipe 406 is provided on one side of the partition plate 2. The drain pipe head 404 is slidably sleeved with the fixed pipe 406. An electric push rod 408 is also provided on the partition plate 2, and the electric push rod 408 drives the drain pipe head 404 to telescope relative to the fixed pipe 406.

[0052] In a preferred solution, a flexible hose 409 is provided inside the drain pipe head 404. One end of the flexible hose 409 passes through the fixed pipe 406 to communicate with the sampling pipe 19. A downwardly bent pipe 407 is provided at the front end of the drain pipe head 404. The other end of the flexible hose 409 is communicated with the bent pipe 407. A corrugated part 410 is provided in the middle of the flexible hose 409 to enable the length of the flexible hose 409 to be variable.

[0053] A through-hole is provided on the side wall of the fixed pipe 406 near the partition plate 2, and the drain turbine 9 passes through here.

[0054] The bent pipe 407 can be detached to facilitate the replacement of the drain turbine 9.

[0055] In a preferred embodiment, a plurality of peristaltic pumps 403 are provided at the connection section between the sampling pipe 19 and the flexible hose 409, and an expansion pipe 411 is connected between adjacent peristaltic pumps 403.

[0056] When the expansion pipe 411 returns, it has the same diameter as the sampling pipe 19 and will expand when too much liquid is filled inside, so a certain amount of liquid can be collected.

[0057] The typical structure of the peristaltic pump 403 includes a U-shaped outer housing 417. Inside the U-shaped outer housing 417, there is a rotating disk 418 driven to rotate by a motor with an encoder. Along the circumferential direction near the outer edge of the rotating disk 418, a plurality of rotatable pressing wheels 419 are provided. The sampling pipe 19 is arranged along the inner wall of the U-shaped outer housing 417 and is alternately squeezed by the plurality of pressing wheels 419, and the liquid in the pipe is pumped forward in a peristaltic manner in sections. Since the pumping volume per single circle is a fixed value and the encoder records the number of circles, the peristaltic pump 403 has the function of measuring the pumping volume. When the pressing wheels 419 do not rotate, they press the pipeline tightly to seal the pipeline.

[0058] In a preferred embodiment, an upper concave cavity 412 is provided at the bottom end of the hull 1. A weighted cover 405 is arranged inside the upper concave cavity 412. A connecting counterbore 414 is provided at the upper end of the weighted cover 405. A pipe sleeve 413 connected by threads is arranged in the connecting counterbore 414. The pipe sleeve 413 is fixedly sleeved with one end of the sampling pipe 19. A magnet 415 is provided at the upper bottom end of the upper concave cavity 412, and an adsorbed block 416 is provided at the upper end of the weighted cover 405. The magnet 415 adsorbs the adsorbed block 416.

[0059] The pipe sleeve 413 is provided with a through hole, so that the end of the sampling pipe 19 is freely communicated with the external water body.

[0060] A sealing ring is provided on the outer side wall of the weighted cover 405 to play a sealing role between the weighted cover 405 and the upper concave cavity 412.

[0061] The sampling pipe 19 has a certain tensile strength and can not only be used as a sampling pipe but also as a lifting rope to lift the weighted cover 405 to block the upper concave cavity 412, and the magnet 415 adsorbs the adsorbed block 416.

[0062] The self-weight of the weighted cover 405 is greater than the adsorption force of the magnet 415 and the friction force between the weighted cover 405 and the upper concave cavity 412. When the sampling pipe 19 is lowered, the weighted cover 405 is disengaged downward, driving the lower end of the sampling pipe 19 to penetrate into the water body to a set depth.

[0063] In a preferred embodiment, the sampling method is as follows:

[0064] Drive the hull 1 to travel to the first designated water area and stop;

[0065] Rotate the sampling pipe reel 402 to lower the weighted cover 405 to the first depth in the first water area;

[0066] The bent pipe 407 is moved to align with the drain hole 306, and each peristaltic pump 403 works synchronously to pump water and discharge it into the drain hole 306 for pipe washing. At this time, each expansion pipe 411 is not expanded.

[0067] The peristaltic pump 403 closest to the bent pipe 407 is denoted as the first peristaltic pump. The first peristaltic pump is turned off. Due to the structural characteristics of the peristaltic pump, the sampling pipe 19 is shut off here. The expansion pipe 411 closest to the bent pipe 407 is denoted as the first expansion pipe. The first expansion pipe expands under the action of water pressure and stores the liquid at the first depth in the first water area. At this time, the first expansion pipe is not filled to the set collection amount, which is denoted as the nearly full collection amount.

[0068] Each peristaltic pump 403 pauses, and the weighted cover 405 is lowered to the second depth.

[0069] The second peristaltic pump adjacent to the first peristaltic pump and the third peristaltic pump adjacent to the second peristaltic pump continue to work, and use the residual water in the sampling pipe 19 to fill the first expansion pipe. The first expansion pipe reaches the full collection amount, and the second peristaltic pump is turned off.

[0070] The third peristaltic pump continues to work to fill the second expansion pipe adjacent to the first expansion pipe to the nearly full collection amount, and uses the residual water in the sampling pipe 19 to make the second expansion pipe reach the full collection amount.

[0071] According to the above steps, adjust the depth of the weighted cover 405 and the working state of each peristaltic pump 403 so that each expansion pipe 411 reaches the full collection amount.

[0072] The weighted cover 405 rises to block the upper concave cavity 412.

[0073] The hull 1 moves to the second water area. During the movement, the drain pipe head 404 retracts so that the bent pipe 407 aligns with the sampling pipe 19 in the placement cavity 303.

[0074] The first peristaltic pump is turned on to pump the water in the first expansion pipe into the sampling pipe 19.

[0075] The placement turntable 301 rotates to switch the sampling pipe 19, and the subsequent peristaltic pumps 403 at the rear end are sequentially turned on to pump the water in the remaining expansion pipes into the respective sampling pipes 19.

[0076] The hull 1 reaches the subsequent water areas and samples according to the above steps until the sampling at each depth in each water area is completed, and then remotely controls the hull 1 to return.

The placement cavities 303 are equidistantly opened on the outside of the top of the placement turntable 301, and the placement base 305 is movably connected to the inner cavity of the placement cavity 303. The drainage hole 306 runs from the top of the placement turntable 301 to the bottom of the hull 1. The input end of the sampling tube reel 402 is fixedly connected to the top of the counterweight cover 405, and the output end of the sampling tube reel 402 is connected to the input end of the water pump through a pipeline, and the output end of the water pump is connected to the input end of the drainage pipe head 404 through a pipeline. A sealing gasket is provided on the contact surface between the counterweight cover 405 and the hull 1, and a test tube is provided in the inner cavity of the placement cavity 303.

[0080] By adopting the above scheme: through the setting of the sealing pad with counterweight cover 405, the phenomenon of water infiltrating into the inner cavity of the hull 1 due to the increase of water pressure during the movement of the hull 1 can be avoided.

[0082] With the above scheme: Through the setting of the turbine chamber cylinder 8, the water flow can flow into the interior of the drainage turbine 9 better, thereby increasing the propulsion force when the drainage turbine 9 propels. Through the setting of the drainage turbine 9, drainage can be carried out to generate propulsion force, so that the device can move on the water surface. Through the setting of the camera 10, the field of vision at the front end of the device can be observed, making it more convenient to control the device.

[0083] Working principle:

[0084] During use, each component of the device is operated and controlled through a remote control device and a remote control system. The remote control signal is received by the signal receiving device 12 and transmitted to the remote control system. The position information of the device is monitored by the positioning and monitoring device 11. The front view of the hull 1 is observed through the camera 10, and the device information is transmitted to the remote control device through the signal receiving device 12 for observation. The sealing cover 5 is loosened to separate it from the hull 1 and removed. The filled test tubes are sequentially placed in the inner cavity of the placement cavity 303, and each placement cavity 303 is marked to distinguish the filled test tubes. Then the sealing cover 5 is reinstalled, and the bottom end of the tube pressing part 6 presses the opening of the filled test tube. The downward movement of the tube pressing part 6 drives the filled test tube to move downward, pushing the placement base 305 to move downward. The downward movement of the placement base 305 causes the spring 304 to contract, pressing the sample storage tube 18 tightly.Place this device on the water surface. By controlling the drainage turbine 9 to work, the water in the inner cavity of the turbine chamber 8 is discharged backward. The device is pushed to move forward by the reaction force of drainage. According to the positioning information, observe the device to stop after traveling to the designated sampling water area, and mark the position information through the remote control. Then control the servo motor to work to drive the sampling tube reel 402 to rotate and release the tube, and control the length of the released tube according to the usage requirements. Drive the water pipe to sink to the designated depth by driving the weighted cover 405. Then control the driving device 302 to work to drive the placement turntable 301 to rotate, so as to drive the test tube holder to rotate to the lower side of the output end of the drain pipe head 404, and extend through the drain pipe head 404 to the inside of the sinking notch 7, so that the output end of the drain pipe head 404 corresponds to the opening of the test tube holder. After the test tube holder rotates to the lower side of the drain pipe head 404, the placement base 305 is pushed to rise by the springback characteristic of the spring 304 to drive the test tube holder to rise, so that the opening of the test tube holder is close to the output end of the drain pipe head 404, so that splashing will not occur during the drainage process of the drain pipe head 404. At this time, control the water pump to work to suck the water sample in the sampling water area and transport it to the drain pipe head 404 for discharging into the inner cavity of the test tube holder. After sampling, drive the test tube holder to move to the bottom of the tube pressing part 6 by rotating the placement turntable 301. During the process, due to the inclined surface design of the sinking notch 7, the test tube holder slowly moves down, and the bottom of the tube pressing part 6 presses against the opening of the test tube holder, so that the opening of the test tube holder is sealed and will not leak. Then wind up the water pipe, control the device to travel to the next water area, and perform the above operations again to collect the water sample of this water area into the next test tube holder. The difference is that before the water sample is pumped into the test tube holder, it is necessary to first control the drain pipe head 404 to extend so that the output end of the drain pipe head 404 corresponds to the opening of the drain hole 306. First, discharge the water sample in the water pipe from the previous water area into the inner cavity of the drain hole 306, and discharge it to the outside of the device through the drain hole 306. At the same time, flush the water sample in the water pipe from the previous water area with the water sample of this water area, so that the water samples in different water areas will not be mixed. And through the marking of different test tube holders corresponding to the position and depth information of the sampling water area, the water samples can be better distinguished.

[0085] In summary, for this small water body water quality monitoring and sampling device, through the coordinated work of each component, it solves the problem that in the actual use process of existing equipment, it is impossible to perform multiple samplings in multiple places in a large water area at one time, resulting in a cumbersome sampling process and an increase in the time cost of sampling in multiple places.
