Description

Technical Field

[0001] This utility model relates to the field of underwater hydrological sampling technology, specifically to an automatic underwater hydrological parameter sampling device. Background Technology

[0002] Automatic underwater hydrological parameter sampling devices are core equipment for hydrological monitoring, ecological protection, and environmental governance, and are widely used in rivers, lakes, oceans, and groundwater environments. By integrating sensors and sampling mechanisms, they can automatically collect key parameters such as water temperature, dissolved oxygen, turbidity, and pollutant concentrations, providing continuous data support for water resource management, pollution prevention and control, and ecological assessment. Especially in unattended remote areas or complex underwater environments, they can effectively reduce the cost and safety risks of manual sampling. A typical device consists of a refrigerated box, sampler, buttons, display screen, sampling port, and peristaltic tube.

[0003] The aforementioned and existing related technologies often have the following drawbacks: when the peristaltic tube is retrieved after underwater sampling, residual water is easily left behind. This residual water will mix with the water sample taken next time, which can easily lead to distorted parameter detection, especially for samples with low concentrations of pollutants or microorganisms. At the same time, the outer wall of the peristaltic tube is prone to the adhesion of impurities such as mud, algae and so on underwater. If it is not cleaned in time, it can easily lead to difficulties in retrieval by personnel and cause certain inconveniences. Long-term accumulation can also breed bacteria, aggravate cross-contamination of samples, and affect the stability of the device and the reliability of sampling data.

[0004] Therefore, we propose an automatic underwater hydrological parameter sampling device. Utility Model Content

Two fixed plates are provided, with a screw threaded through the surface of each fixed plate. A connecting plate is rotatably connected to the lower end of the screw. A rotating rod is fixedly connected to one side of the two connecting plates that are close to each other. A roller is rotatably connected to the arc surface of the rotating rod. An extrusion rod is fixedly connected to one side of the two fixed plates that are close to each other. An extrusion wheel is rotatably connected to the arc surface of the extrusion rod.

A ring is fixedly connected to the upper surface of the locking rod. A cleaning ring is fixedly connected to the inner wall of the ring.

[0007] The aforementioned components achieve the effect of squeezing and cleaning the peristaltic tube of the automatic underwater hydrological parameter sampling device, thereby minimizing the problem of water residue inside the peristaltic tube after sampling and debris adhering to the surface, which could easily lead to cross-sampling in subsequent sampling and inconvenience for personnel retrieval.

[0008] Preferably, a rotating plate is fixedly connected to the upper end of the screw, and an arc groove is formed on the arc surface of the roller.

[0009] The effect achieved by the above components is that the peristaltic tube moves within the arc groove of the roller, and the arc groove plays a role in assisting in positioning and centering the peristaltic tube.

[0010] Preferably, the cross-section of the clamping rod is triangular, and the size of the clamping rod is adapted to the inner wall size of the V-shaped frame.

[0011] The aforementioned components achieve the following effect: by using a lever with a triangular cross-section, a detachable cleaning ring can be removed for cleaning.

[0012] Preferably, a magnet is fixedly connected to the lower surface of the V-shaped frame, and an inner groove is formed on the upper surface of the magnet. The lower surface of the lever is attracted to the inner groove of the inner wall of the magnet.

[0013] The effect achieved by the above components is that the lever moves to the inner wall of the inner groove and is attracted to the magnet, and the magnet plays a better role in limiting the lever.

[0014] Preferably, the upper surface of the sampler is provided with a limiting structure, the limiting structure including a rectangular box, the lower surface of the rectangular box being fixedly connected to the sampler, a positioning rod being fixedly connected to the inner wall of the rectangular box, a long rod being fixedly connected to one side of the inner wall of the rectangular box, a pull plate being slidably connected to the arc surface of the long rod, and a limiting rod being fixedly connected to the upper surface of the pull plate.

[0015] The aforementioned components achieve the following effect: they limit the position of the retracted peristaltic tube, making it easier to place and retrieve it during underwater sampling in different areas, thus improving the ease of operation for personnel.

[0016] Preferably, a spring is fixedly connected to the side of the pull plate away from the positioning rod, the spring is sleeved on the arc surface of the long rod, and the other end of the spring is fixedly connected to the inner wall of the rectangular box.

[0017] The effect achieved by the above components is that the movement of the pull plate causes the spring to extend and retract, and the spring further fixes the peristaltic tube.

[0018] Preferably, the two sides of the pull plate are slidably connected to the inner wall of the rectangular box, and the positioning rod is an inverted conical rod.

[0019] The effect achieved by the above-mentioned components is to effectively prevent the peristaltic tube from springing back upwards as a positioning rod for the inverted cone rod.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] This invention, through the design of a squeezing structure, achieves the effect of squeezing and cleaning the peristaltic tube of an automatic underwater hydrological parameter sampling device. The double roller squeezing effectively removes residual water from the peristaltic tube, effectively avoiding detection errors caused by the mixing of new and old water samples, and ensuring the originality and accuracy of the samples. The annular cleaning ring can simultaneously clean impurities attached to the outer wall when the tube is retracted, facilitating subsequent recycling and reuse. This not only improves the accuracy of sampling data but also reduces the maintenance frequency of the equipment, extends its service life, and enhances the applicability of the device in complex underwater environments.

[0022] This invention achieves the effect of limiting the retracted peristaltic tube by setting a limiting structure. By limiting the retracted peristaltic tube, it is easier to place it during underwater sampling in different areas and to retrieve it more easily, thus improving the convenience of personnel operation.

[0029] 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.

[0030] Please see Figure 1 This utility model provides a technical solution: an automatic underwater hydrological parameter sampling device, including a refrigerated box 1, a sampler 2 connected to the upper surface of the refrigerated box 1, several buttons 3 fixedly connected to one side of the sampler 2, a display screen 4 fixedly connected to the side of the sampler 2 opposite to the buttons 3, a sampling port 5 connected to one side of the sampler 2, and a squeezing structure 6 provided above the sampling port 5 of the sampler 2, which achieves the effect of squeezing and cleaning the peristaltic tube of the automatic underwater hydrological parameter sampling device, thereby minimizing the problem of water residue in the peristaltic tube after sampling and debris adhering to the surface, which can easily lead to cross-sampling in subsequent sampling and inconvenience for personnel retrieval. A limiting structure 7 is provided on the upper surface of the sampler 2, which achieves the effect of limiting the peristaltic tube after retrieval. By limiting the peristaltic tube after retrieval, it is convenient to place it during the underwater sampling process in different areas, and it is easier to pick it up, improving the convenience of personnel operation.

[0031] The specific design and function of its extrusion structure 6 and limiting structure 7 will be explained below.

[0032] like Figure 2 - Figure 5 As shown, the extrusion structure 6 includes a U-shaped plate 601. One side of the U-shaped plate 601 is fixedly connected to the sampler 2. Two fixing plates 602 are fixedly connected to the side of the U-shaped plate 601 away from the sampler 2. A screw 603 is threaded through the surface of the fixing plate 602. A connecting plate 604 is rotatably connected to the lower end of the screw 603. A rotating rod 605 is fixedly connected to the side of the two connecting plates 604 that is close to each other. A roller 606 is rotatably connected to the arc surface of the rotating rod 605. An extrusion rod 607 is fixedly connected to the side of the two fixing plates 602 that is close to each other. A squeezing wheel 608 is rotatably connected to the arc surface of rod 607. A V-shaped frame 609 is fixedly connected to one side of the two connecting plates 604. A locking rod 610 slides through the inner wall of the V-shaped frame 609. A ring 611 is fixedly connected to the upper surface of the locking rod 610. A cleaning ring 612 is fixedly connected to the inner wall of the ring 611. A rotating plate 613 is fixedly connected to the upper end of the screw 603. An arc groove 614 is opened on the arc surface of the roller 606. The peristaltic tube moves in the arc groove 614 of the roller 606. The arc groove 614 plays a role in assisting in positioning and centering the peristaltic tube.

[0033] The cross-section of the lever 610 is triangular, and the size of the lever 610 is adapted to the inner wall size of the V-shaped frame 609. The lever 610 with its triangular cross-section achieves the effect of cleaning the detachable cleaning ring 612. A magnet 615 is fixedly connected to the lower surface of the V-shaped frame 609. An inner groove 616 is opened on the upper surface of the magnet 615. The lower surface of the lever 610 is attracted to the inner groove 616 of the inner wall of the magnet 615. The lever 610 moves to the inner wall of the inner groove 616 and is attracted to the magnet 615. The magnet 615 plays a better role in limiting the position of the lever 610.

[0034] like Figure 2 As shown, the limiting structure 7 includes a rectangular box 71. The lower surface of the rectangular box 71 is fixedly connected to the sampler 2. A positioning rod 72 is fixedly connected to the inner wall of the rectangular box 71. A long rod 73 is fixedly connected to one side of the inner wall of the rectangular box 71. A pull plate 74 is slidably connected to the arc surface of the long rod 73. A limiting rod 75 is fixedly connected to the upper surface of the pull plate 74. A spring 76 is fixedly connected to the side of the pull plate 74 away from the positioning rod 72. The spring 76 is sleeved on the arc surface of the long rod 73. The other end of the spring 76 is fixedly connected to the inner wall of the rectangular box 71. The movement of the pull plate 74 causes the spring 76 to extend and retract. The spring 76 further fixes the peristaltic tube. The two sides of the pull plate 74 are slidably connected to the inner wall of the rectangular box 71. The positioning rod 72 is an inverted conical rod. The inverted conical positioning rod 72 effectively prevents the peristaltic tube from springing back upward.

[0035] Working principle: When automatic sampling of underwater hydrological parameters is required, the refrigerated container 1 is first moved to the underwater area to be monitored and sampled. Then, the peristaltic tube is released from its own limit by the limiting structure 7, and one end of the peristaltic tube is passed between the cleaning ring 612, the roller 606, and the squeezing roller 608. Finally, it is fitted onto the arc surface of the sampling port 5. Then, the sampling time interval or trigger condition is set by the button 3 of the sampler 2. When the sampling time is reached, the pump inside the sampler 2 will automatically draw underwater water into the sampling port through the peristaltic tube. Inside the sampler 2, sensors measure hydrological parameters such as water temperature, dissolved oxygen, and turbidity in real time and record the data, which is then displayed on the screen 4. After water sampling is completed, the collected water sample can be refrigerated in the refrigerator 1. The parameter data recorded by the sensors in the sampler 2 is transmitted to the ground control console via line signals. After sampling, the peristaltic tube is moved out from the arc surface of the sampling port 5, and then the water contact position inside the peristaltic tube is moved between the roller 606 and the squeezing roller 608. At this time, the two rotating plates 613 are rotated, and the screw... The rod 603 is lifted by the rotation of the rotating plate 613 with the help of the fixed plate 602. The connecting plate 604, with the help of the screw 603 and the rotating rod 605, drives the arc groove 614 of the roller 606 to fit and squeeze the peristaltic tube. The arc groove 614 plays a role in assisting in positioning and centering the peristaltic tube. After the peristaltic tube is squeezed between the roller 606 and the squeezing wheel 608, the peristaltic tube is pulled to perform a retraction action. The movement of the peristaltic tube causes the squeezing wheel 608 and the roller 606 to rotate, thereby squeezing out the residual water on the inner wall of the peristaltic tube. During the peristaltic tube retrieval process, the cleaning ring 612 at the end performs forced cleaning on the arc surface, removing some attached debris. After cleaning, the moving ring 611 causes the locking rod 610 to detach from the inner wall of the inner groove 616 of the magnet 615. The magnet 615 plays a better role in limiting the locking rod 610. After the locking rod 610 detaches from the inner wall of the V-shaped frame 609, the triangular cross-section of the locking rod 610 enables the cleaning ring 612 to be detached for cleaning. The cleaning ring 612 is removed, allowing it to be cleaned.

[0036] After the peristaltic tube is retrieved, the limiting rod 75 is first pulled towards the side closer to the positioning rod 72. The pull plate 74 slides on the inner wall of the rectangular box 71 and the arc surface of the long rod 73 through the limiting rod 75. At this time, the spring 76 is in a stretched state due to the movement of the pull plate 74. The spring 76 further fixes the peristaltic tube. After the peristaltic tube is sleeved on the arc surface of the positioning rod 72 and the limiting rod 75, the positioning rod 72 of the inverted cone rod effectively prevents the peristaltic tube from springing back upward. The limiting rod 75 is slowly released. At this time, the spring 76 is in a contracted state, which drives the pull plate 74 to return to the arc surface of the long rod 73. The limiting rod 75 then pulls the peristaltic tube through the pull plate 74. The pulling of the limiting rod 75, which is positioned by the positioning rod 72, temporarily limits the rolled-up peristaltic tube on the rectangular box 71 to facilitate subsequent handling and placement.
