Description

Technical Field

[0001] This invention relates to the field of water body detection, and in particular to a water body detection device that can be used for environmental water quality assessment. Background Technology

[0002] Environmental water quality assessment is a comprehensive evaluation process based on certain standards and methods to assess the quality of water bodies. Its aim is to accurately understand the environmental condition of water bodies and provide a scientific basis for water resource protection and management. The main influencing factors include physical, chemical, and biological indicators. Specific assessments require water sampling and analysis of the composition of substances within the water to obtain relevant parameters for physical, chemical, and biological indicators.

[0003] Currently, water body testing generally relies on manual sampling. This not only involves a large workload, but also limits sampling to the banks or, when sampling large bodies of water like rivers, lakes, and lagoons, significantly increasing costs and reducing efficiency. It also fails to achieve efficient and rapid batch and multi-site sampling and testing. Consequently, the sampled water bodies lack high representativeness, and accurate environmental water quality assessment maps cannot be created based on the test results.

[0004] A water sampling device, disclosed in announcement number CN114659850A, relates to the field of water sampling technology. To reduce the number of times a sampler enters and exits the water body, the device includes a probe and a water sampling unit. The water sampling unit includes: a drive motor mounted on the probe; a drive gear mounted on the output shaft of the drive motor; a driven gear mounted on the probe; a chain mounted on the drive and driven gears; and a water sampling cup mounted on the chain, comprising a cup body and a cup lid. The cup lid has a water inlet, and the water inlet is equipped with a solenoid valve. The number of water sampling cups is two or more. Water samples at different depths are obtained simultaneously, avoiding interference with the samples caused by repeated entry into the water body.

[0005] While the aforementioned technical solutions ensure that the water at different levels is not disturbed or mixed during sampling, they still cannot efficiently and quickly perform multi-point water sampling and testing. Therefore, a water body testing device for environmental water quality assessment is proposed. Summary of the Invention

[0011] Preferably, the clamping sleeve is slidably connected to the inner wall of the circular groove, and the upper end of the circular groove is also connected to an arc-shaped cylindrical opening. The clamping sleeve is also slidably connected to the inner wall of the arc-shaped cylindrical opening. The lower end of the telescopic component is connected to a disc, and the water pump is installed on the lower side of the disc. The upper side of the disc is connected to a top rod in an array.

[0012] Preferably, the second drive component includes a servo motor and a gear. The servo motor is mounted on the ring platform, the gear is connected to the output end of the servo motor, and a gear ring that meshes with the gear is fitted on the inner wall of the ring.

[0013] Preferably, the clamping assembly includes a limiting sleeve, a limiting rod, and a clamping plate. The limiting sleeve array is connected to the inner wall of the clamping cylinder. One end of the limiting rod is slidably connected inside the limiting sleeve and connected to the inner wall of the limiting sleeve by a spring, while the other end extends to the outside of the limiting sleeve. The clamping plate is connected to the extension end of the limiting rod on the outside of the limiting sleeve, and each clamping plate is slidably fitted to the outer surface of the sampling cylinder.

The technical solution of the present invention can drive the disc and the top rod to move upward by the contraction of the telescopic component, so that the upper end of the top rod can pass through the opening and abut against the lower end of the ring platform, thereby pushing it to move upward, so that each clamping cylinder gradually moves upward. When the clamping cylinder gradually slides out of the circular groove through the arc-shaped cylinder opening, it will drive the sampling cylinder inside it to flip under the action of the spring hinge, so that the water sampled in the sampling cylinder is poured out, which facilitates the next resampling and realizes continuous automated multiple sampling. 3. The technical solution of the present invention can drive the rudder surface to be parallel to the moving square when the float valve moves, and rotate to a direction perpendicular to the moving direction of the float valve when sampling, so as to quickly stop the movement of the float valve, and at the same time stabilize the float valve when it is stationary and floating, so as to ensure the accuracy of sampling points when sampling and testing at multiple points, and further improve the accuracy of sampling and testing.

[0020] The following will be combined with the appendix Figure 1 To be continued Figure 9 The technical solutions in the embodiments of the present invention have been clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention. Example 1:

[0021] like Figure 1-4 As shown, this invention discloses a water body detection device for environmental water quality assessment, including a float valve 1. The float valve 1 is equipped with a drive component 1 for driving itself. A telescopic component 7 is installed at the bottom of the float valve 1, and a water pump 9 is installed at the lower end of the telescopic component 7. The water pump 9 is connected to a nozzle 12 through a hose. A circular groove 2 is opened on the float valve 1, and a ring platform 14 is slidably connected in the circular groove 2. A ring 16 is rotatably fitted on the ring platform 14, and a drive component 2 is provided on the ring platform 14 to drive the ring 16 to rotate on the ring platform 14. A water quality detection terminal 32 is also slidably installed on the float valve 1. A hose reel is installed on the float valve 1. Due to the winding of the hose with a certain redundant length, when the water pump 9 is driven by the telescopic component 7 to move into the deep water body, the hose can be stretched and unwound, realizing an effective connection between the water pump 9 and the nozzle 12, which facilitates water pumping and sampling. A clamping cylinder 20 is rotatably connected to the ring platform 14 via a spring hinge, and a sampling cylinder 22 is fitted inside the clamping cylinder 20. A clamping assembly is installed inside the clamping cylinder 20 to stably clamp the sampling cylinder 22. Rotary shafts 27 are rotatably connected through both sides of the float valve 1, and a rudder surface 28 is connected to the lower end of the float valve 1 via the rotating shafts 27. A sliding seat 35 is slidably connected to the float valve 1, and a rotating rod 42 is rotatably connected between the sliding seat 35 and the water quality testing terminal 32. An adjustment assembly is also installed on the sliding seat 35 to adjust the angle of the rudder surface 28 to achieve steering drive or... The device stops and stabilizes, while the second drive component can drive the ring 16 to rotate, which is convenient for multi-point sampling. It drives different sampling cylinders 22 on the ring 16 to rotate to the lower side of the nozzle 12 to collect the sample water drawn by the water pump 9 at different points. At the same time, the clamping cylinder 20 and the sampling cylinder 22 on the ring 16 are arranged in an array, but there are two empty spaces in the diameter direction to facilitate the lifting of the ring platform 14, so that the clamping cylinder 20 and the sampling cylinder 22 can rotate under the action of the spring hinge, and the sample water in the sampling cylinder 22 is poured out to achieve continuous sampling and detection.

[0022] The telescopic component 7 is an existing waterproof electric cylinder or electric hydraulic cylinder, etc.

[0023] The drive assembly includes a waterproof electric steering seat 4, a waterproof motor 5, and a propeller 6. The nozzle 12 and the water quality testing terminal 32 are symmetrically arranged on both sides of the diameter of the float valve 1. The waterproof electric steering seat 4 is installed at the bottom of the float valve 1 on both sides of the line connecting the nozzle 12 and the water quality testing terminal 32. The waterproof motor 5 is installed at the output end on the lower side of the waterproof electric steering seat 4, and the propeller 6 is installed at the output end of the waterproof motor 5.

[0024] The waterproof electric steering seat 4 can drive the waterproof motor 5 and propeller 6 to turn. When the waterproof electric steering seats 4 on both sides are running synchronously, they can drive the float valve 1 to move on the water surface and also adjust the direction.

[0025] Multiple guide rods 13 are arrayed on the lower inner wall of the circular groove 2. The annular platform 14 is slidably sleeved on the outer side of each guide rod 13. A spring 15 sleeved on the outside of the guide rod 13 is connected between the annular platform 14 and the upper end of the guide rod 13. A guide rail 34 is installed on the float valve 1, and the slide seat 35 is slidably connected to the guide rail 34.

[0026] The guide rod 13 ensures the stability of the ring platform 14 sliding up and down in the circular groove 2. At the same time, the elastic force of the spring 15 and the weight of the ring platform 14 itself can keep the ring platform 14 at the bottom of the circular groove 2 without external force. The guide rail 34 is the existing electric guide rail 34, which can drive the slide block 35 to slide.

[0027] Multiple brackets 19 are connected to the ring platform 14. The lower end of the clamping cylinder 20 is rotatably connected to the bracket 19 via a spring hinge. A limit frame 21 is also connected to the bracket 19. The limit frame 21 is located on the side of the clamping cylinder 20 near the center of the circular groove 2. A mounting bracket 30 is connected to the float valve 1, and a telescopic rod 31 is mounted on the mounting bracket 30. A water quality testing terminal 32 is connected to the output end of the telescopic rod 31. A water quality testing module 33 is mounted on the float valve 1. The water quality testing module 33 is connected to the water quality monitoring system via a cable. The detection terminal 32 is connected so that each cassette 20 can abut against the inner wall of the circular groove 2 under the action of the spring hinge. The telescopic rod 31 can drive the water quality detection terminal 32 to move up and down by telescoping. When moving up, it can avoid each sampling cassette 22, ensuring that each sampling cassette 22 can be driven to rotate with the circular ring 16 by the drive component 2 to hold the water samples taken from multiple points. When moving down, it can be inserted into the corresponding sampling cassette 22 to detect the sampled water.

[0028] The clamp 20 is slidably connected to the inner wall of the circular groove 2. The upper end of the circular groove 2 is also connected to the arc-shaped cylindrical opening 3. The clamp 20 is also slidably connected to the inner wall of the arc-shaped cylindrical opening 3. The lower end of the telescopic component 7 is connected to the disc 8, and the water pump 9 is installed on the lower side of the disc 8. The upper side of the disc 8 is connected to the top rod 10. Multiple openings 11 corresponding to the top rod 10 are opened through the bottom of the circular groove 2 and the float valve 1. The top rod 10 slides through the opening 11 on its respective side and abuts against the lower end of the ring platform 14.

[0029] In practical use, the telescopic component 7 can drive the water pump 9 to move to different water depths for sampling. When each sampling cylinder 22 is filled with sample water, by controlling the telescopic component 7 to retract, the top rod 10 passes through the opening 11 and abuts against the ring platform 14, causing it to move upward and compress the spring 15. As it moves upward, each clamping cylinder 20 will gradually flip outward through the arc-shaped cylinder opening 3 to the outside of the circular groove 2, thereby tilting the sample water in the sampling cylinder 22 to achieve continuous sampling. At the same time, when the device is equipped with the existing remote control module, it can be remotely controlled to achieve continuous multi-point and multi-depth sampling and testing, ensuring the representativeness of the sampling and testing, facilitating accurate assessment of environmental water quality, and enabling more accurate drawing of environmental water quality assessment atlases.

[0030] The arc-shaped opening 3 also minimizes the backflow of water samples into the circular groove 2 when the sample water is poured. The limiting frame 21 ensures that the clamping cylinder 20 does not over-rotate when it is flipped. This ensures that when the ring platform 14 moves down and resets, the clamping cylinder 20 can again contact the arc-shaped opening 3 and the inner wall of the circular groove 2 and rotate back to a vertical position, which is convenient for sampling. Example 2:

[0031] like Figure 1-5As shown, the present invention discloses a water body detection device for environmental water quality assessment. Compared with Embodiment 1, this embodiment discloses the structure of the driving component 2.

[0032] The second drive component includes a servo motor 17 and a gear 18. The servo motor 17 is mounted on the ring platform 14, and the gear 18 is connected to the output end of the servo motor 17. The inner wall of the ring 16 is fitted with a gear ring that meshes with the gear 18. This enables the ring 16 to rotate relative to the ring platform 14, thereby rotating the sampling cylinder 22 to continuously collect samples from the nozzle 12 and continuously cooperate with the water quality testing terminal 32 for water quality testing. Example 3:

[0033] like Figure 1-7 As shown, the present invention discloses a water body detection device for environmental water quality assessment. Compared with Embodiment 2, this embodiment discloses the structure of the card-mounted component.

[0034] The clamping assembly includes a limiting sleeve 23, a limiting rod 24, and a clamping plate 26. The limiting sleeves 23 are arrayed and connected to the inner wall of the clamping cylinder 20. One end of the limiting rod 24 is slidably connected inside the limiting sleeve 23 and is connected to the inner wall of the limiting sleeve 23 by a spring 25, while the other end extends to the outside of the limiting sleeve 23. The clamping plate 26 is connected to the extension end of the limiting rod 24 on the outside of the limiting sleeve 23. Each clamping plate 26 is slidably attached to the outer side of the sampling cylinder 22.

[0035] This causes the clamping plates 26 to move closer to each other under the action of the spring 25. When the sampling cylinder 22 is inserted between the clamping plates 26, the clamping plates 26 can clamp and stabilize the sampling cylinder 22. Example 4:

[0036] like Figure 1-9 As shown, the present invention discloses a water body detection device for environmental water quality assessment. Compared with Embodiment 3, this embodiment discloses the structure of the adjustment component.

[0037] The adjustment assembly includes a second gear 29, a mounting frame 36, a second servo motor 37, a connecting plate 38, an arc-shaped rack 39, and a linear rack 41. The second gear 29 is mounted on one end of the rotating shaft 27 on the upper side of the float valve 1. The mounting frame 36 is connected to the slide block 35. The second servo motor 37 is mounted on the mounting frame 36. The connecting plate 38 is connected to the output end of the second servo motor 37. The arc-shaped rack 39 is symmetrically connected to both sides of the connecting plate 38. The linear rack 41 is slidably connected to the float valve 1, and the linear rack 41 is connected to both the second gear 29 and the arc-shaped rack 39.

[0038] A slide 40 is connected to the float valve 1. A linear rack 41 is slidably sleeved on the outer side of the slide 40. An arc rack 39 is located on the rear side of the gear 29. The linear rack 41 is located on the two rotating shafts 27 on the side of the gear 29 that is far apart from each other.

[0039] In practical use, when the float valve 1 needs to be stopped and sampled, the guide rail 34 can drive the slide 35 to move forward, thereby driving the connecting plate 38 and the arc rack 39 to move forward synchronously, so that the straight rack 41 also moves forward. Through the two rotating shafts 27 and the gear 29, the two rudder surfaces 28 are driven from a state parallel to the direction of movement of the float valve 1 to a state perpendicular to it, so as to quickly stop the float valve 1 and stabilize its floating, so as to facilitate stable water pumping and sampling. At this time, since the propeller 6 is located behind the water pump 9, the disturbance of the water body by the propeller 6 will not affect the sampling of the water pump 9. Furthermore, when the float valve 1 needs to turn during movement, it can be done through the waterproof electric steering seat 4. At the same time, the connecting plate 38 can be rotated by controlling the servo motor 37, which in turn drives the arc-shaped racks 39 on both sides to slide back and forth, thereby driving the linear racks 41 on both sides to move back and forth. Through meshing, the rotating shafts 27 on both sides and the rudder surface 28 rotate synchronously to one side. Their rotation direction is consistent with the rotation direction of the waterproof electric steering seat 4, which can assist the steering movement of the float valve 1 and further improve the efficiency and stability of the float valve 1's steering.

[0040] A support plate 43 is connected to the rear side of the slide 35, and a rotating shaft 27 is also fitted through the rear end of the support plate 43. The lower end of the rotating shaft 27 is also connected to the same rudder surface 28. The upper end of the rotating shaft 27 on the support plate 43 is connected to the same sprocket 44 on the connecting plate 38. A chain 45 is fitted between the two sprockets 44, so that there is another rudder surface 28 on the rear side of the float valve 1, forming a three-rudder surface structure. When the rudder surfaces 28 on both sides rotate to one side to assist the waterproof electric steering seat 4 in steering the float valve 1, the rotating shaft 27 and the rudder surface 28 on the support plate 43 can also rotate in the same direction under the linkage of the chain 45 and the sprocket 44, further improving the efficiency and stability of the rotation of the float valve 1.

[0041] Based on the disclosure and teachings of the foregoing specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the protection scope of the claims of the present invention. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the present invention.
