Description

Technical Field

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

[0002] A water sampling and testing device is a device used to obtain and analyze water samples. It can provide important data for water resource management, pollution monitoring and ecological protection. This device is commonly used in environmental monitoring, water quality testing, scientific research and water source management, and conducts chemical, biological and physical analyses.

[0003] Currently, existing water sampling and testing devices suffer from several drawbacks. Most are fixed in length and can only sample water sources within a certain depth range, making it difficult to adjust the sampling depth according to actual needs. This reduces the applicability of the equipment. Furthermore, most existing sampling devices can only sample water sources at one depth at a time, making it inconvenient to sample water sources at different depths simultaneously. This is time-consuming and labor-intensive, further reducing the practicality of the equipment. Therefore, a new water sampling and testing device is urgently needed to solve these problems. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a water source sampling and testing device to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a water source sampling and testing device, comprising:

[0006] An adjustment structure is provided with a fixing ring on the outer wall surface at the upper end of the adjustment structure, and a sampling structure is provided on the outer surface of one side of the lower end of the adjustment structure. A wire wheel is inserted into the inner part of the outer surface of one side of the fixing ring, and a connecting wire is sleeved on the outer surface of the wire wheel.

[0007] The adjustment structure includes a first sleeve rod, and a fixing ring is fixedly connected to the outer wall surface of the upper end of the first sleeve rod;

[0008] The sampling structure includes a placement rack, and the placement rack is provided in multiple sets;

[0009] The adjustment structure also includes a first clamping bolt, which is threaded into the interior of the outer surface of the lower end of the first sleeve rod. A second sleeve rod is inserted inside the first sleeve rod, and the second clamping bolt is threaded into the interior of the outer surface of the lower end of the second sleeve rod. A third sleeve rod is inserted inside the second sleeve rod, and the third clamping bolt is threaded into the interior of the outer surface of the lower end of the third sleeve rod. A moving rod is inserted inside the third sleeve rod. A placement frame is fixedly connected to the outer surface of the other side of the lower end of the first sleeve rod, the second sleeve rod, the third sleeve rod, and the moving rod. This design allows the second sleeve rod, the third sleeve rod, and the moving rod to move inside the first sleeve rod, the second sleeve rod, and the third sleeve rod respectively. Rotating the first clamping bolt, the second clamping bolt, and the third clamping bolt allows the outer surface of one end of each bolt to press against the outer surface of the second sleeve rod, the third sleeve rod, and the moving rod respectively, thereby fixing the positions of the second sleeve rod, the third sleeve rod, the moving rod, and the first sleeve rod, the second sleeve rod, and the third sleeve rod respectively.

[0010] The sampling structure also includes a fourth clamping bolt. The fourth clamping bolt is internally threaded on the outer surface of one side of the placement rack, and a sampling box is inserted inside the upper end of the placement rack. A box cover is hinged to the outer surface of the upper end of the sampling box, and a connecting ring is fixedly connected to the outer surface of one end of the box cover. A clip is inserted inside the connecting ring, and the outer surface of one side of the clip is fixedly connected to the outer surface of one end of the connecting line. This design allows the outer surface of one end of the fourth clamping bolt to be pressed against the outer surface of the sampling box when rotated, thereby fixing the position between the sampling box and the placement rack.

[0011] Preferably, a limiting ring is provided on the outer surface of the upper end of the second sleeve rod, the third sleeve rod, and the moving rod, and the outer dimensions of the limiting ring are adapted to the inner dimensions of the first sleeve rod, the second sleeve rod, and the third sleeve rod, respectively. This design ensures that the second sleeve rod, the third sleeve rod, and the moving rod will not move out of the interior of the first sleeve rod, the second sleeve rod, and the third sleeve rod when they move.

[0012] Preferably, the inner diameter of the placement rack is adapted to the outer diameter of the sampling box. This design allows the sampling box to be inserted into the placement rack, and the insertion is more stable.

[0013] Preferably, a torsion spring is provided inside the hinged connection between the sampling box and the lid, and a torsion spring is provided inside the clip. This design allows the outer surface of the upper end of the sampling box to fit against the lower surface of the lid through the elasticity of the torsion spring itself, and allows it to automatically reset itself after the lid is opened by hinge rotation.

[0014] The technical effects and advantages of this utility model are as follows: This utility model uses a second sleeve rod, a third sleeve rod, and a moving rod to move inside the first sleeve rod, the second sleeve rod, and the third sleeve rod respectively. After moving, they can be fixed by the first clamping bolt, the second clamping bolt, and the third clamping bolt respectively. This allows for flexible adjustment of the length of the equipment and facilitates adjustment of the water sampling depth according to actual needs, thereby improving the applicability of the equipment to a certain extent.

[0015] Multiple sets of placement frames are fixedly connected to the outer surface of the lower end of the first, second, and third sets of rods and the other side of the moving rod, enabling simultaneous sampling of water sources at different depths. Subsequently, rotating the reel causes the connecting line to be stored on the outer surface of the reel, thereby driving multiple sets of clamps to move upward. At this time, the box cover can be hinged and rotated open through the connecting ring. After sampling is completed, the reel is released, and the box cover can be hinged and rotated closed by the elasticity of the torsion spring. This makes the equipment more time-saving and labor-saving during sampling, improving the practicality of the equipment to a certain extent. Moreover, its overall structure is simple and reasonable in design, highly practical, and easy to promote and apply. Attached Figure Description

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The water source sampling and detection device involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1

[0023] like Figures 1-2 As shown, this embodiment proposes a water source sampling and detection device, including:

[0024] Adjustment structure 1 includes a first sleeve rod 11, with a fixing ring 2 fixedly connected to the outer wall surface of the upper end of the first sleeve rod 11. Adjustment structure 1 also includes a first clamping bolt 12, which is threadedly connected to the interior of the lower end outer surface of the first sleeve rod 11. A second sleeve rod 13 is inserted inside the first sleeve rod 11, and a second clamping bolt 14 is threadedly connected to the interior of the lower end outer surface of the second sleeve rod 13. A third sleeve rod 15 is inserted inside the second sleeve rod 13. A third clamping bolt 16 is threaded on the inner surface of the lower end of the rod 15, and a moving rod 17 is inserted inside the third sleeve rod 15. A placement frame 31 is fixedly connected to the outer surface of the lower end of the first sleeve rod 11, the second sleeve rod 13, the third sleeve rod 15 and the moving rod 17. A limit ring is provided on the outer surface of the upper end of the second sleeve rod 13, the third sleeve rod 15 and the moving rod 17, and the external dimensions of the limit ring are adapted to the internal dimensions of the first sleeve rod 11, the second sleeve rod 13 and the third sleeve rod 15 respectively.

[0025] In this embodiment, the positions of the second sleeve rod 13, the third sleeve rod 15, and the moving rod 17 inside the first sleeve rod 11, the second sleeve rod 13, and the third sleeve rod 15 are adjusted according to the specific sampling depth required. The limiting rings on the upper outer surfaces of the second sleeve rod 13, the third sleeve rod 15, and the moving rod 17 prevent them from detaching from the interior of the first sleeve rod 11, the second sleeve rod 13, and the third sleeve rod 15. When the second sleeve rod 13, the third sleeve rod 15, and the moving rod 17 move to a suitable position, the first clamping bolt 12, the second clamping bolt 14, and the third clamping bolt 16 can be rotated so that the outer surfaces of one end of the first clamping bolt 12, the second clamping bolt 14, and the third clamping bolt 16 respectively abut against the outer surfaces of the second sleeve rod 13, the third sleeve rod 15, and the moving rod 17, thus fixing the positions of the second sleeve rod 13, the third sleeve rod 15, and the moving rod 17 inside the first sleeve rod 11, the second sleeve rod 13, and the third sleeve rod 15.

[0026] Example 2

[0027] like Figures 3-4 As shown, based on the same concept as the above embodiments, this embodiment also proposes:

[0028] A fixing ring 2 is provided on the outer wall surface of the upper end of the adjustment structure 1, and a sampling structure 3 is provided on the outer surface of one side of the lower end of the adjustment structure 1. A wire wheel 4 is inserted inside the outer surface of one side of the fixing ring 2, and a connecting wire 5 is sleeved on the outer surface of the wire wheel 4. The sampling structure 3 includes a placement frame 31, and the placement frame 31 is provided with multiple sets. The sampling structure 3 also includes a fourth clamping bolt 32. The fourth clamping bolt 32 is threadedly connected to the inner surface of one side of the outer surface of the placement frame 31, and a sampling box 33 is inserted inside the upper end of the placement frame 31. A box cover 34 is hinged to the outer surface of the upper end of the sampling box 33, and a connecting ring 35 is fixedly connected to the outer surface of one end of the box cover 34. A clip 36 is inserted inside the connecting ring 35, and the outer surface of one side of the clip 36 is fixedly connected to the outer surface of one end of the connecting wire 5. The inner diameter of the placement frame 31 is adapted to the outer diameter of the sampling box 33. A torsion spring is provided inside the hinged connection between the sampling box 33 and the box cover 34, and a torsion spring is provided inside the clip 36.

[0029] In this embodiment, multiple sampling boxes 33 are inserted into the upper part of multiple placement racks 31 respectively. The fourth clamping bolt 32 is rotated so that the outer surface of one end of it presses against the outer surface of the sampling box 33, which can fix the position of the sampling box 33. It is fixedly connected to the outer surface of multiple clamps 36 through the connecting line 5. Rotating the thread wheel 4 causes the connecting line 5 to move upward, which can drive the multiple clamps 36 to move upward, and pull the connecting ring 35 to move upward. This allows the multiple box covers 34 to open simultaneously through hinge rotation. Thus, water sources at different depths can be sampled at the same time. After sampling, the thread wheel 4 is released, and the box cover 34 can automatically return to its original position through the elasticity of the torsion spring.

[0030] Working principle: When using the equipment, firstly, according to the required sampling depth, adjust the positions of the second sleeve rod 13, the third sleeve rod 15, and the moving rod 17 inside the first sleeve rod 11, the second sleeve rod 13, and the third sleeve rod 15 respectively. Then, fix the positions of the second sleeve rod 13, the third sleeve rod 15, and the moving rod 17 inside the first sleeve rod 11, the second sleeve rod 13, and the third sleeve rod 15 by rotating the first clamping bolt 12, the second clamping bolt 14, and the third clamping bolt 16. Next, insert multiple sets of sampling boxes 33 into the multiple sets of placement racks 31 respectively, and fix the positions of the sampling boxes 33 inside the placement racks 31 by rotating the fourth clamping bolt 32. Then, open the clamp 36 through the torsion spring and insert it into the connecting ring 35. The torsion spring's elasticity allows for automatic clamping. Then... Multiple clamps 36 are fixed to the outer surface of the connecting line 5 by knotting or other means. At this time, the device can be immersed in water for sampling. When the device is placed in the required position, the reel 4 is rotated to move the connecting line 5 upward, which in turn moves the clamps 36 and the connecting ring 35 upward. This allows multiple boxes 34 to open by hinged rotation, enabling the device to sample at different depths. After sampling, the reel 4 is released, and the elasticity of the torsion spring causes the box 34 to automatically reset and fit tightly against the sampling box 33. This prevents water samples from flowing out of the sampling box 33 and water from flowing in when the device is pulled out of the water. Then, the fourth locking bolt 32 is rotated in the opposite direction and the clamps 36 are opened to remove the sampling box 33 for water sample testing. This is the complete working principle of this utility model.
