Description

Technical Field

[0001] This utility model relates to the field of water source environment monitoring technology, and more specifically, it relates to a water source environment monitoring sampling device. Background Technology

[0002] Technological advancements and accelerated processes of intelligentization and industrialization have brought water pollution to the forefront, making water quality testing of paramount importance. However, current water sampling still requires manual on-site operations, with samples then sent back to the laboratory for testing.

[0003] Currently, most sampling methods use drones to carry sampling equipment, but this method still has the following problems: 1. Currently, drones can only carry a single water tank for multi-point sampling over large water areas. After completing sampling at each location, they must fly back to shore to replace the empty tank. This repeated back-and-forth flight consumes a significant amount of operational time, making the overall sampling process lengthy and inefficient, and significantly reducing the speed of covering multiple target points.

[0004] 2. Existing sampling methods using water tanks can only obtain samples from the surface layer of the water body and cannot reach water layers at different depths. However, lake water quality often varies significantly in the vertical direction, and relying solely on surface water samples cannot comprehensively and accurately reflect the overall water quality of the water body.

[0005] 3. During drone flight, especially when accelerating, decelerating, turning, or encountering turbulence, the suspended water tank will shake violently. This shaking can easily cause the collected water sample inside the tank to splash out or overflow, resulting in unexpected loss of sample volume and affecting the accuracy and reliability of subsequent water quality test results.

[0006] Therefore, there is an urgent need to develop a water source environment monitoring and sampling device. Utility Model Content

[0007] (a) Technical problems to be solved In view of the problems existing in the prior art, this utility model provides a water source environment monitoring and sampling device to solve the technical problems mentioned in the background art.

[0008] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a water source environment monitoring sampling device, comprising a drone, a connecting rope fixedly connected to the lower side of the drone, a connecting cover fixedly connected to the lower end of the connecting rope, a threaded shell fixedly connected to the connecting cover, a bottom shell threadedly connected to the threaded shell, fixing clips evenly distributed circumferentially fixed to the inner wall of the bottom shell, a fixing ring fixedly connected to the inner wall of the bottom shell, a sliding ring slidably connected to the bottom shell, a spring fixedly connected between the sliding ring and the fixing ring, extrusion members evenly distributed circumferentially fixed to the sliding ring, a sampling structure provided inside the fixing clips, and a driving structure provided in the connecting cover.

[0009] The present invention is further configured such that the sliding ring is press-fitted with the lower side of the connecting cover.

[0010] The present invention is further provided that the middle part of the extrusion member is provided with a groove.

[0011] The present invention is further provided that the bottom of the bottom shell is provided with through holes distributed at equal intervals in the circumferential direction, and a sealing ring is installed in each of the through holes of the bottom shell.

[0012] The present invention is further configured such that the sampling structure includes a fixed tube, the fixed ring is snapped into the fixed clip, the top of the fixed tube is threadedly connected to a top cover, the top cover is limitedly fitted with the extrusion piece, the fixed tube passes through the through hole of the bottom shell, a piston is slidably connected inside the fixed tube, a sliding rod is slidably connected to the top cover, the sliding rod is fixedly connected to the piston, and a limiting plate is fixedly connected to the top end of the sliding rod.

[0013] The present invention is further provided that a sealing ball is provided inside the fixed tube.

[0014] The present invention is further configured such that the driving structure includes a rotating sleeve, the rotating sleeve is rotatably connected to the lower side of the connecting cover, an electric push rod is fixedly connected to the middle of the rotating sleeve, a connecting plate is fixedly connected to the telescopic end of the electric push rod, and the connecting plate is limited in a limiting fit with the limiting plate.

[0015] The present invention is further configured such that a motor is fixedly connected to the connecting cover, a gear is fixedly connected to the output shaft of the motor, a gear ring is fixedly connected to the rotating sleeve, the gear ring meshes with the gear, a control power supply is fixedly connected to the top of the connecting cover, the control power supply is electrically connected to the motor and the electric push rod, and the control power supply is signal connected to the handheld controller.

[0016] (III) Beneficial Effects Compared with the prior art, the present invention provides a water source environment monitoring and sampling device, which has the following beneficial effects: 1. This utility model, by setting multiple fixing clips and corresponding sampling tubes at equal intervals along the circumference inside the bottom shell, enables the drone to carry multiple sampling units in a single flight. When sampling different locations in large water areas, there is no need to frequently travel back and forth to change containers, allowing for multi-point sampling to be completed in one go, greatly shortening the operation time and significantly improving the overall sampling efficiency.

[0017] 2. This utility model employs a unique piston-driven structure combined with electric push rod control. By precisely triggering the piston's upward movement underwater, negative pressure is generated within the fixed tube, actively drawing in surrounding water. This method overcomes the limitation of traditional water tanks that can only obtain surface water, effectively collecting water samples at a set depth and better reflecting the vertical stratification of the water body.

[0018] 3. This utility model utilizes a spring-loaded sliding ring and a pressing component to press the top cover and fixing tube tightly during assembly, ensuring a tight fit with the sealing ring at the bottom shell's through-hole, forming a reliable seal. This structure effectively buffers vibration and shaking during flight, preventing water sample splashing and ensuring sample integrity and subsequent testing accuracy. Attached Figure Description

A bottom shell 5 is threadedly connected to the threaded shell 4. Fixed clips 6 are circumferentially evenly distributed and fixed to the inner wall of the bottom shell 5. A fixed ring 7 is fixedly connected to the inner wall of the bottom shell 5. A sliding ring 8 is slidably connected to the bottom shell 5. A spring 9 is fixedly connected between the sliding ring 8 and the fixed ring 7. An extrusion member 10 is circumferentially evenly distributed and fixed to the sliding ring 8. A sampling structure is provided in the fixed clip 6. A driving structure is provided in the connecting cover 3. The sliding ring 8 is pressed and engaged with the lower side of the connecting cover 3. A groove is provided in the middle of the extrusion member 10. A through hole is provided at a circumferentially evenly distributed and a sealing ring is installed in each through hole of the bottom shell 5.

[0025] Please see Figures 3-5 The sampling structure includes a fixed tube 11, a fixed ring 7 that is snapped into a fixed clip 6, a top cover 12 that is threaded to the top of the fixed tube 11, the top cover 12 that is limited to the extrusion piece 10, the fixed tube 11 that passes through the through hole of the bottom shell 5, a piston 13 that is slidably connected inside the fixed tube 11, a sliding rod 14 that is slidably connected to the top cover 12, the sliding rod 14 that is fixed to the piston 13, and a limit plate 15 that is fixed to the top of the sliding rod 14; a sealing ball is provided inside the fixed tube 11.

[0026] Please see Figure 3 and Figure 6 The drive structure includes a rotating sleeve 17, which is rotatably connected to the lower side of the connecting cover 3. An electric push rod 18 is fixedly connected to the middle of the rotating sleeve 17. A connecting plate 19 is fixedly connected to the telescopic end of the electric push rod 18. The connecting plate 19 is in a limiting fit with the limiting plate 15. A motor 20 is fixedly connected to the connecting cover 3. A gear 21 is fixedly connected to the output shaft of the motor 20. A gear ring 22 is fixedly connected to the rotating sleeve 17. The gear ring 22 meshes with the gear 21. A control power supply 23 is fixedly connected to the top of the connecting cover 3. The control power supply 23 is electrically connected to the motor 20 and the electric push rod 18. The control power supply 23 is also signal connected to the handheld controller.

[0027] The working principle of this utility model is as follows: Before using this device for sampling, the fixing tube 11 needs to be inserted into the fixing clip 6, and the sliding rod 14 needs to be located in the groove of the extrusion member 10, with the extrusion member 10 located above the top cover 12. Then, the threaded shell 4 and the bottom shell 5 are tightened together, and the connecting cover 3 presses the sliding ring 8 downward. The sliding ring 8 drives the extrusion member 10 to press the top cover 12, and the spring 9 is compressed, thereby causing the fixing tube 11 to press the sealing ring in the through hole of the bottom shell 5, so that the fixing tube 11 and the bottom shell 5 are in a sealed connection state.

[0028] When the bottom shell 5 is tightened, the electric push rod 18 and the connecting plate 19 are located inside the bottom shell 5, and the height of the connecting plate 19 is lower than that of the limiting plate 15. The drone 1 is controlled to fly along the water surface. When the drone 1 flies to the designated point, the drone 1 is moved downward until the bottom shell 5 and the connecting cover 3 are below the water surface. The handheld controller sends a signal to the control power supply 23, and the control power supply 23 supplies power to the motor 20. The output shaft of the motor 20 drives the gear ring 22 to rotate through the gear ring 22. At this time, the rotating sleeve 17 rotates along the connecting cover 3. The rotating sleeve 17 drives the electric push rod 18 to rotate, so that the connecting plate 19 is located below one of the limiting plates 15. Then the motor 20 is turned off, and the control power supply 23 supplies power to the electric push rod 18. The telescopic end of the electric push rod 18 drives the connecting plate 19 to move upward. Then the connecting plate 19 cooperates with the limiting plate 15, so that the sliding rod 14 drives the piston 13 to move upward.

[0029] As piston 13 moves upward, negative pressure is created inside fixed tube 11, allowing water to enter the interior. Simultaneously, the water impacts the metal sealing ball 16. When piston 13 reaches the top, electric push rod 18 drives connecting plate 19 to reset, while metal sealing ball 16 seals the lower part of fixed tube 11. Then, drone 1 is controlled to move upward, removing bottom shell 5 and connecting cover 3 from the water. Drone 1 then flies to other sampling areas, repeating the above operation to ensure all fixed tubes 11 sample the river water. Finally, motor 20 is controlled to reset rotating sleeve 17 and electric push rod 18, preventing the connecting wires of electric push rod 18 from becoming tangled.

[0030] After sampling is completed, remove the fixed tube 11 from the fixed clip 6, then rotate the top cover 12 and remove the piston 13 from the fixed tube 11, thus emptying the sample from the fixed tube 11 for subsequent testing.

[0031] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model.
