Description

Technical Field

[0001] This utility model relates to the field of water quality testing technology, specifically to a portable water quality testing sampling device. Background Technology

[0002] In today's environmental monitoring field, water quality testing is a key link in assessing the health status of water bodies. With the increasing emphasis on water resource protection and utilization, water quality testing is becoming more frequent and complex. From rivers and lakes to oceans, from drinking water sources to industrial wastewater discharge outlets, precise water sample collection and analysis are required. However, traditional water quality sampling devices have revealed many problems in practical applications.

[0003] Traditional water sampling devices, especially those designed for specific water areas or testing projects, involve an extremely cumbersome process when switching water samples between different water areas or for various testing needs. For example, with common integrated sampling bottles, changing the water sample often requires disassembling, cleaning, drying, and reassembling the entire bottle. This process is not only time-consuming, but also carries the risk of residual cleaning agents or impurities during cleaning, which can affect the purity of subsequent water samples and thus interfere with the accuracy of the test results. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a portable water quality testing sampling device, which solves the problem of the extremely cumbersome process of switching water samples when facing different water areas or multiple testing needs.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a portable water quality testing sampling device, comprising a fixed plate and a storage component. The bottom of the storage component is fixedly connected to the top of the fixed plate, and the outer wall of the storage component is connected to a suction component. The storage component includes an outer tube, the top of which is fixedly connected to a threaded ring. A threaded disc is threadedly connected to the inner wall of the threaded ring, and an inlet pipe is fixedly connected to the inner wall of the threaded disc. An inner tube is fixedly connected to the bottom of the threaded disc. Both the outer and inner tubes are made of rubber. Thus, when the sampling device needs to be stored, only the inner and outer tubes need to be folded, making it easy to carry the sampling device.

[0008] Preferably, the bottom of the outer tube is fixedly connected to the top of the fixed plate, and the wall of the fixed plate is provided with a threaded groove.

[0009] Preferably, the suction assembly includes a suction shell, with one-way tubes fixedly connected to the outer walls on both sides of the suction shell. A liquid suction tube is sleeved on the outer wall of the one-way tube. A flow guide tube is sleeved on the top of the suction shell through a one-way valve. The inner wall of the top of the suction shell is fixedly connected to the outer wall of the one-way valve. The one-way valve only allows the liquid inside the suction shell to flow through the flow guide tube.

[0010] Preferably, a converging tube is fixedly connected to the end of the guide tube away from the suction shell, a piston block is slidably connected to the inner wall of the suction shell, a pull rope is fixedly connected to the inner wall of the piston block, the outer wall of the pull rope is slidably connected to the inner wall of the suction shell, and the outer wall of the suction shell is fixedly connected to the outer wall of the threaded ring.

[0011] Preferably, the inner wall of the collecting pipe is fitted onto the outer wall of the inlet pipe.

[0012] (III) Beneficial Effects

[0013] This invention provides a portable water quality testing sampling device. It offers the following advantages:

[0014] (i) This portable water quality testing sampling device allows the inner tube to be easily removed from the storage assembly by rotating the threaded disc, facilitating the replacement of the water sample in the inner tube. This design enables the device to quickly switch water samples in different water areas or for different testing projects without the need for complicated cleaning or replacement of the entire storage assembly. For example, when conducting continuous multi-point water quality testing, it can efficiently collect and store water samples from different locations separately, improving the versatility and flexibility of the device.

[0015] (II) This portable water quality testing sampling device uses a suction component to control the movement of a piston block by pulling a rope, thereby achieving the extraction and transport of water samples. The operation process is simple and intuitive. With just a simple pulling action, the water sample can be collected and transferred under the action of external atmospheric pressure using the principles of fluid mechanics. No complicated equipment operation skills are required, which lowers the skill threshold for operators. Even those who are using the device for the first time can quickly get started and successfully complete the water sample collection work. Attached Figure Description

[0022] 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.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a portable water quality testing sampling device, including a fixed plate 1 and a storage component 2. The bottom of the storage component 2 is fixedly connected to the top of the fixed plate 1, and the outer wall of the storage component 2 is connected to a suction component 3. The storage component 2 includes an outer tube 21, a threaded ring 22 is fixedly connected to the top of the outer tube 21, a threaded disc 23 is threadedly connected to the inner wall of the threaded ring 22, an inlet pipe 25 is fixedly connected to the inner wall of the threaded disc 23, and an inner tube 24 is fixedly connected to the bottom of the threaded disc 23. The bottom of the outer tube 21 is fixedly connected to the top of the fixed plate 1. By rotating the threaded disc 23, the positions of the inner tube 24 and the inlet pipe 25 can be adjusted to adapt to the water sample collection needs at different depths or positions. On the other hand, during the carrying of the device, the tight threaded connection ensures that the components will not loosen, ensuring the integrity of the device. Moreover, by rotating the threaded disc 23, the inner tube 24 can be easily removed from the storage component 2, allowing the water sample in the inner tube 24 to be replaced.

[0024] The suction assembly 3 includes a suction shell 36. One-way tubes 35 are fixedly connected to the outer walls on both sides of the suction shell 36. A liquid suction tube 34 is sleeved on the outer wall of the one-way tube 35. A guide tube 32 is sleeved on the top of the suction shell 36 through a one-way valve. A converging tube 33 is fixedly connected to the end of the guide tube 32 away from the suction shell 36. A piston block 38 is slidably connected to the inner wall of the suction shell 36. A pull rope 39 is fixedly connected to the inner wall of the piston block 38.

[0025] The outer wall of the pull rope 39 is slidably connected to the inner wall of the suction shell 36. The outer wall of the suction shell 36 is fixedly connected to the outer wall of the threaded ring 22. The inner wall of the converging pipe 33 is sleeved with the outer wall of the inlet pipe 25. When the operator pulls the pull rope 39, the piston block 38 slides on the inner wall of the suction shell 36. According to the principle of fluid mechanics, the movement of the piston block 38 increases the space on one side of the suction shell 36 and reduces the pressure, forming a negative pressure environment. Under the action of the external atmospheric pressure, the water sample enters the one-way pipe 35 through the suction pipe 34. Due to the action of the one-way valve in the one-way pipe 35, the water sample can only flow into the suction shell 36 in one direction. When the piston block 38 reaches one side of the suction shell 36, the operator pulls the other end of the pull rope 39 in the opposite direction to force the water sample in the suction shell 36 into the inlet pipe 25 through the guide pipe 32 and the converging pipe 33.

[0026] When using,

[0027] The device mainly consists of a fixed plate 1, a storage component 2, and a suction component 3. The components work together to achieve convenient and efficient water sampling. The fixed plate 1 serves as the basic support component of the entire sampling device, providing a stable installation platform for the storage component 2. The bottom of the storage component 2 is firmly fixed to the top of the fixed plate 1, ensuring the overall stability of the device during carrying and use. The storage component 2 not only undertakes the function of storing samples, but is also closely connected with the suction component 3. The two work together to complete the water sample collection process.

[0028] The core structure of the storage assembly 2 includes an outer tube 21, a threaded ring 22, a threaded disc 23, an inner tube 24, and an inlet pipe 25. The outer tube 21 serves as an external protective and support structure. The threaded ring 22 fixed at its top engages with the threaded disc 23 via a threaded connection. This threaded connection design is adjustable and stable. On the one hand, when water samples need to be collected, the positions of the inner tube 24 and the inlet pipe 25 can be adjusted by rotating the threaded disc 23 to accommodate water sample collection needs at different depths or locations. On the other hand, during device transport, the tight threaded connection ensures that the components do not loosen, guaranteeing the integrity of the device. Furthermore, by rotating the threaded disc 23, the inner tube 24 can be easily removed from the storage assembly 2 to replace the water sample in the inner tube 24.

[0029] The suction assembly 3 mainly consists of a suction shell 36, a one-way tube 35, a liquid extraction tube 34, a guide tube 32, a converging tube 33, a piston block 38, and a pull rope 39. The one-way tubes 35, which are fixed to the outer walls on both sides of the suction shell 36, are fitted with the liquid extraction tubes 34 on their outer walls for extracting water samples from the outside. The guide tube 32 is fitted to the top of the suction shell 36 through a one-way valve. The end of the guide tube 32 away from the suction shell 36 is connected to the converging tube 33, which is fitted with the liquid inlet tube 25 to form a complete water sample delivery path. The piston block 38 can slide on the inner wall of the suction shell 36, and the pull rope 39 is fixedly connected to its inner wall. The movement of the piston block 38 can be controlled by pulling the pull rope 39.

[0030] When water samples need to be extracted, the operator pulls the pull rope 39, causing the piston block 38 to slide on the inner wall of the suction shell 36. According to the principles of fluid mechanics, the movement of the piston block 38 increases the space on one side of the suction shell 36, reduces the pressure, and creates a negative pressure environment. Under the action of external atmospheric pressure, the water sample enters the one-way pipe 35 through the extraction pipe 34. Due to the action of the one-way valve in the one-way pipe 35, the water sample can only flow into the suction shell 36 in one direction. When the piston block 38 reaches one side of the suction shell 36, the operator pulls the other end of the pull rope 39 in the opposite direction, forcing the water sample in the suction shell 36 into the inlet pipe 25 through the guide pipe 32 and the converging pipe 33, and finally into the outer pipe 21 of the receiving component 2 for storage. In this process, the one-way valve ensures that the water sample can only flow in the predetermined direction, avoids backflow of the water sample, and ensures the smooth progress of the water sample extraction and transportation process.
