Description

Technical Field

[0001] The utility model relates to the technical field of water quality sampling devices, and more specifically, it relates to a water quality sampling device. Background Technique

[0002] In the existing water quality sampling technology, there are some problems and limitations. Traditional sampling devices usually adopt the method of extending the sampling pipeline into the river to extract water samples, but this design has encountered some challenges in practice:

[0003] Firstly, the pipeline length of the existing sampling device is usually fixed and long, which causes inconvenience in storage and handling. The overly long pipeline is not only difficult to store reasonably when the device is not in use, but also increases the overall weight and volume of the device, making it extremely inconvenient to move the device to different sampling points. In addition, different usage scenarios may require pipelines of different lengths, while the existing technology often cannot flexibly adapt to this demand, resulting in limitations in actual applications and affecting the efficiency and flexibility of the sampling work.

[0004] Secondly, the simplicity of the internal structure of the pipeline in the existing technology limits its ability to control the water extraction speed. During the water quality sampling process, controlling the extraction speed is very important because different water quality analysis requirements may require different flow rates to ensure the representativeness of the samples. However, the existing devices often lack this fine-tuning ability, resulting in the inability to obtain ideal sampling results in specific situations.

[0005] In addition, although some existing devices attempt to adjust the water extraction speed through some adjustment mechanisms, the designs of these mechanisms are usually relatively simple and lack stability. During the operation of the device, due to the vibration of the device or the influence of external factors, the adjustment device is prone to looseness, which will cause the adjusted flow rate to change, thus affecting the accuracy and reliability of the sampling results. The existence of this instability makes it difficult for the sampling device to maintain consistent sampling conditions in actual applications, having an adverse impact on water quality analysis.

[0017] (3) Beneficial effects

[0018] Compared with the prior art, the utility model provides a water quality sampling device, which has the following beneficial effects:

[0019] 1. Through the design of components such as the connecting pipe, mounting bracket, communicating vessel, and winch, the storage device realizes the convenient storage and release of the sampling pipeline. The cooperation of the winch and the motor enables the connecting pipe to be conveniently released or retrieved, saving space and improving the portability of the device.

[0032] An output pipe 17 is provided on one side of the connecting pipe 3.

[0033] A slide rail 18 is provided on the outer side of the fixed pipe 4, and a chute 19 is formed on the inner side of the sliding sleeve 12. The chute 19 is adapted to the slide rail 18.

[0034] A fixing plate 20 is provided on the outer side of the fixed pipe 4. A tension spring 21 is provided on one side of the fixing plate 20, and the other end of the tension spring 21 is connected to the sliding sleeve 12.

[0035] An activity frame 22 is movably provided inside the rotating sleeve 10. Two ends of the elastic plate 6 are respectively connected to the activity frame 22 and the external thread sleeve 8.

[0036] In this embodiment, when it is necessary to adjust the water extraction speed, first rotate the rotating plate. The rotating plate will drive the arc-shaped groove 15 and the through groove 16 to move. When the positions of the through groove 16 and the limiting plate 13 correspond, the tension spring 21 pulls the sliding sleeve 12 to reset. Then the sliding sleeve 12 will slide along the slide rail 18 and the chute 19. At the same time, the sliding sleeve 12 will drive the limiting rod 14 and the limiting plate 13 to be withdrawn from the through groove 16. Then the outer side of the rotating sleeve 10 loses the limitation of the sliding sleeve 12. Then rotate the rotating sleeve 10. The rotating sleeve 10 drives the connecting frame 5 inside to rotate. The connecting frame 5 drives the square rod 9 to rotate. The square rod 9 drives the external thread sleeve 8 to rotate through the square sleeve 7. Since the external thread sleeve 8 and the inner wall of the fixed pipe 4 are movably connected by threads, then the external thread sleeve 8 will perform a spiral movement along the fixed pipe 4. At the same time, the thread sleeve will slide along the square rod 9 and the square sleeve 7. Then the distance between the external thread sleeve 8 and the activity frame 22 changes, so that the gap between the elastic plates 6 changes, thereby changing the water flow through speed. After adjustment, pull the sliding sleeve 12, so that the sliding sleeve 12 slides along the slide rail 18 and the chute 19. At the same time, the sliding sleeve 12 will drive the tension spring 21 to stretch. Then the limiting rod 14 and the limiting plate 13 provided on one side of the sliding sleeve 12 will pass through the through groove 16. Then rotate the rotating plate 11 in the reverse direction, so that the rotating plate 11 drives the arc-shaped groove 15 and the through groove 16 to move. Then the limiting rod 14 will enter the arc-shaped groove 15. At the same time, the limiting plate 13 will be clamped on one side of the rotating plate 11, so as to realize the limitation of the sliding sleeve 12, and further enable the sliding sleeve 12 to form a stable limitation on the rotating sleeve 10, ensuring the stability after adjustment.

[0037] Please refer to Figure 1 , as an implementation manner of the storage device: The storage device includes a connecting pipe 23, a mounting frame 24, a communicating vessel 25 and a winch 26. The mounting frame 24 is detachably mounted on the fixed frame 1. The winch 26 is movably mounted inside the mounting frame 24. The communicating vessel 25 is detachably mounted on one side of the mounting frame 24. The connecting pipe 23 is wound around the outer side of the winch 26, and one end of the connecting pipe 23 passes through the communicating vessel 25 and is connected to the fixed pipe 4.

[0038] A fixed rod 27 is provided on the outer side of the winch 26. The fixed rod 27 is detachably mounted inside the mounting frame 24.

[0039] On one side of the mounting bracket 24, there is a motor 28, and the output end of the motor 28 is connected to one end of the hoisting wheel 26.

[0040] More specifically, when the device needs to be used, first move the device to the designated location, then turn on the motor 28. The motor 28 drives the hoister to rotate, so that the connecting pipe 23 is released. Then insert the input end of the connecting pipe 23 into the river water. Then turn on the water pump 2. The water pump 2 pumps the river water through the connecting pipe 23, then reaches the communicating vessel 25, then enters the connecting pipe 3, and is then conveyed through the output pipe 17 to an external detection device for water quality sampling and detection.

[0041] In summary, when the overall device is in use or operation: when it is necessary to adjust the water extraction speed, first rotate the rotating plate. The rotating plate will drive the arc-shaped groove 15 and the through groove 16 to move. When the position of the through groove 16 corresponds to the position of the limiting plate 13, the tension spring 21 pulls the sliding sleeve 12 to reset. Then the sliding sleeve 12 will slide along the slide rail 18 and the chute 19. At the same time, the sliding sleeve 12 will drive the limiting rod 14 and the limiting plate 13 to be pulled out from the through groove 16. Then the outside of the rotating sleeve 10 loses the limitation of the sliding sleeve 12. Then rotate the rotating sleeve 10. The rotating sleeve 10 drives the connecting frame 5 inside to rotate. The connecting frame 5 drives the square rod 9 to rotate. The square rod 9 drives the external thread sleeve 8 to rotate through the square sleeve 7. Since the external thread sleeve 8 and the inner wall of the fixed pipe 4 are movably connected by threads, then the external thread sleeve 8 will move spirally along the fixed pipe 4. At the same time, the thread sleeve will slide along the square rod 9 and the square sleeve 7. Then the distance between the external thread sleeve 8 and the movable frame 22 changes, so that the gap between the elastic plates 6 changes, thereby changing the water flow through speed. After adjustment, pull the sliding sleeve 12, so that the sliding sleeve 12 slides along the slide rail 18 and the chute 19. At the same time, the sliding sleeve 12 will drive the tension spring 21 to stretch. Then the limiting rod 14 and the limiting plate 13 arranged on one side of the sliding sleeve 12 will pass through the through groove 16. Then rotate the rotating plate 11 in the reverse direction, so that the rotating plate 11 drives the arc-shaped groove 15 and the through groove 16 to move. Then the limiting rod 14 will enter the arc-shaped groove 15. At the same time, the limiting plate 13 will be clamped on one side of the rotating plate 11, thereby realizing the limitation of the sliding sleeve 12, and further enabling the sliding sleeve 12 to form a stable limitation on the rotating sleeve 10, ensuring the stability after adjustment.

[0042] When the device needs to be used, first move the device to the designated location, then turn on the motor 28. The motor 28 drives the hoister to rotate, so that the connecting pipe 23 is released. Then insert the input end of the connecting pipe 23 into the river water. Then turn on the water pump 2. The water pump 2 pumps the river water through the connecting pipe 23, then reaches the communicating vessel 25, then enters the connecting pipe 3, and is then conveyed through the output pipe 17 to an external detection device for water quality sampling and detection.

[0043] Among all the solutions mentioned above, for the connection between two components, welding, the connection with bolts and nuts, bolt or screw connection, or other well-known connection methods can be selected according to the actual situation, which will not be elaborated one by one here. For those mentioned above that involve fixed connection, welding is preferably considered.
