Description

Technical Field

[0001] This utility model belongs to the field of water quality analysis and testing technology, and in particular relates to a water sampling device for water quality analysis and testing. Background Technology

[0002] River water quality analysis and testing are conducted to understand the content of nutrients (such as nitrogen and phosphorus) in the river water and assess the risk of eutrophication. If the content of nutrients such as nitrogen and phosphorus is too high, it may lead to the proliferation of algae and disrupt the ecological balance of the river.

[0003] However, the above-mentioned device still has the following problems during implementation:

[0004] Existing technologies make water sampling devices convenient for extracting water from rivers. However, the containers on these devices have a specific capacity. When more water needs to be collected for analysis and testing, it is necessary to collect the water in two batches, which is quite troublesome. Therefore, a water sampling device for water quality analysis and testing is proposed to solve the above problems. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a water sampling device for water quality analysis and testing, which has the advantage of adjustable water intake. It can overcome the above-mentioned problems or at least partially solve the problem that water sampling devices are designed to facilitate the extraction of water from river water, but the containers on the water sampling devices are all of a specific capacity. When more water needs to be extracted for analysis and testing, it is necessary to extract it in batches twice, which is quite troublesome.

[0006] This utility model is implemented as follows: a water sampling device for water quality analysis and testing includes a U-shaped plate, a collection tube, a connecting rod, and a handle. The left and right sides of the collection tube are fixedly connected to the U-shaped plate, the front side of the U-shaped plate is fixedly connected to the connecting rod, and the front side of the connecting rod is fixedly connected to the handle.

[0007] The surface of the collection tube is fitted with a lifting shell, the front side of the lifting shell is provided with a matching groove, and a rotating rod is movably connected to the front side of the lifting shell;

[0008] A positioning component is disposed within the inner cavity of the grip.

[0009] As a preferred embodiment of this utility model, the surface of the collecting tube is provided with a matching groove, and the side of the collecting tube near the matching groove contacts the surface of the matching groove. By providing the matching groove, when the lifting shell moves up and down, the matching groove can match the lifting shell, so that the lifting shell will not move randomly or detach when it moves on the surface of the collecting tube.

[0010] As a preferred embodiment of this utility model, a tooth is fixedly connected to the left side of the inner cavity of the mating groove, and there are multiple teeth. A gear is meshed with the right side of the teeth. The front side of the gear is fixedly connected to the rotating rod. By setting the teeth and gear, when it is necessary to control the lifting shell to adjust to different positions, the meshing of the gear and teeth can better control the lifting shell to move to different positions and facilitate positioning.

[0011] As a preferred embodiment of this utility model, a positioning element is sleeved on the surface of the rotating rod. The side of the positioning element near the connecting rod is fixedly connected to the connecting rod. A positioning groove is formed on the surface of the rotating rod to cooperate with the positioning element. The inner wall of the positioning groove is in contact with the positioning element. By setting the positioning element and the positioning groove, when the rotating rod rotates, because the positioning element is fixedly connected to the connecting rod, the positioning groove and the positioning groove match, which can increase the stability of the rotating rod when rotating.

[0012] In a preferred embodiment of this invention, a first transmission wheel is fixedly connected to the front side of the rotating rod, and a second transmission wheel is sleeved on the surface of the connecting rod. A transmission belt is sleeved on the surfaces of the first and second transmission wheels. By setting the first transmission wheel, the second transmission wheel, and the transmission belt, when it is necessary to conveniently control the rotation of the gear, rotating the rotating ring drives the second transmission wheel to rotate. The second transmission wheel will drive the first transmission wheel to rotate through the transmission belt. The rotation of the first transmission wheel will drive the rotating rod to rotate, and the rotation of the rotating rod will drive the gear to mesh with the teeth.

[0013] In a preferred embodiment of this invention, a rotating ring is fixedly connected to the front side of the second transmission wheel. The rotating ring has multiple insertion holes on its front side. A limiting groove is provided on the surface of the grip rod to cooperate with the rotating ring. The inner wall of the rotating ring contacts the inner wall of the limiting groove. By setting the rotating ring, insertion holes, and limiting groove, the limiting groove can control the position of the rotating ring when it is rotated. When the rotating ring rotates to different positions, the corresponding insertion holes can be connected with the insertion rod.

[0014] In a preferred embodiment of this invention, the positioning component includes a limiting groove, which is located at the top of the grip. A pull block is slidably connected to the inner cavity of the limiting groove. A spring is fixedly connected to the front side of the pull block, and a plug-in rod for use with a plug-in hole is fixedly connected to the rear side of the pull block. The plug-in rod is inserted into the inner cavity of the plug-in hole. By setting the positioning component, after the plug-in rod is inserted into the plug-in hole, the spring pressure on the pull block allows the pull block to apply force to the plug-in rod, thus preventing the plug-in rod from detaching.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention utilizes a combination of a handle, a lifting shell, a mating groove, a rotating rod, and a positioning component. The rotation of the first transmission wheel drives the rotating rod to rotate, which in turn drives the gears to mesh, thus lowering the lifting shell. This solves the problem that water sampling devices are designed for convenient water extraction from rivers, but the containers on these devices have a specific capacity. When more water needs to be collected for analysis, it is necessary to collect it in two batches, which is quite cumbersome. Attached Figure Description

[0022] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0023] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] like Figures 1 to 4 As shown in the figure, the water sampling device for water quality analysis and testing provided by this utility model includes a U-shaped plate 1, a collection tube 2, a connecting rod 3 and a handle 4. The left and right sides of the collection tube 2 are fixedly connected to the U-shaped plate 1, the front side of the U-shaped plate 1 is fixedly connected to the connecting rod 3, and the front side of the connecting rod 3 is fixedly connected to the handle 4.

[0025] A lifting shell 5 is fitted onto the surface of the collecting pipe 2. A matching groove 6 is provided on the front side of the lifting shell 5. A rotating rod 7 is movably connected to the front side of the lifting shell 5.

[0026] Positioning component 8 is disposed in the inner cavity of grip 4.

[0027] refer to Figure 3 The surface of the collection tube 2 is provided with an anastomosis groove 9, and the side of the collection tube 2 near the anastomosis groove 9 is in contact with the surface of the anastomosis groove 9.

[0028] The above solution is adopted: by setting the matching groove 9, the matching groove 9 can match the lifting shell 5 when the lifting shell 5 moves up and down. In this way, the lifting shell 5 will not move randomly or detach when it moves on the surface of the collecting tube 2.

[0029] refer to Figure 3 A tooth 10 is fixedly connected to the left side of the inner cavity of the groove 6, and there are multiple teeth 10. A gear 11 is meshed with the right side of the tooth 10, and the front side of the gear 11 is fixedly connected to the rotating rod 7.

[0030] The above scheme is adopted: by setting teeth 10 and gears 11, when it is necessary to control the lifting shell 5 to adjust to different positions, the meshing of gears 11 and teeth 10 can better control the lifting shell 5 to move to different positions and facilitate positioning.

[0031] refer to Figure 2 A positioning element 12 is sleeved on the surface of the rotating rod 7. The side of the positioning element 12 near the connecting rod 3 is fixedly connected to the connecting rod 3. A positioning groove 13 is opened on the surface of the rotating rod 7 to cooperate with the positioning element 12. The inner wall of the positioning groove 13 is in contact with the positioning element 12.

[0032] The above solution is adopted: by setting the positioning component 12 and the positioning groove 13, when the rotating rod 7 rotates, because the positioning component 12 is fixedly connected to the connecting rod 3, the positioning groove 13 and the positioning groove 13 match, which can increase the stability of the rotating rod 7 when rotating.

[0033] refer to Figure 1 and Figure 2 The front side of the rotating rod 7 is fixedly connected to the first transmission wheel 14, and the surface of the connecting rod 3 is fitted with the second transmission wheel 15. The surfaces of the first transmission wheel 14 and the second transmission wheel 15 are fitted with the transmission belt 16.

[0034] Using the above scheme: by setting the first transmission wheel 14, the second transmission wheel 15 and the transmission belt 16, when it is necessary to conveniently control the rotation of the gear 11, the rotating ring 17 drives the second transmission wheel 15 to rotate, the second transmission wheel 15 will drive the first transmission wheel 14 to rotate through the transmission belt 16, the rotation of the first transmission wheel 14 will drive the rotating rod 7 to rotate, and the rotation of the rotating rod 7 will drive the gear 11 to mesh with the teeth 10.

[0035] refer to Figure 2A rotating ring 17 is fixedly connected to the front side of the second transmission wheel 15. The rotating ring 17 has a plurality of insertion holes 18 on its front side. A limiting groove 19 is provided on the surface of the grip 4 to cooperate with the rotating ring 17. The inner wall of the rotating ring 17 contacts the inner wall of the limiting groove 19.

[0036] Using the above scheme: by setting a rotating ring 17, a plug hole 18 and a limiting groove 19, when the rotating ring 17 is rotated, the limiting groove 19 can control the position of the rotating ring 17. When the rotating ring 17 is rotated to different positions, the corresponding plug hole 18 can be connected with the plug rod 84.

[0037] refer to Figure 4 The positioning component 8 includes a limiting slide groove 81, which is opened at the top of the grip 4. A pull block 82 is slidably connected to the inner cavity of the limiting slide groove 81. A spring 83 is fixedly connected to the front side of the pull block 82. A plug rod 84 that mates with the plug hole 18 is fixedly connected to the rear side of the pull block 82. The plug rod 84 is plugged into the inner cavity of the plug hole 18.

[0038] Using the above solution: After the positioning component 8 is set and the plug rod 84 is inserted into the plug hole 18, the spring 83 applies pressure to the pull block 82, so that the pull block 82 can apply force to the plug rod 84, thus preventing the plug rod 84 from coming off.

[0039] The working principle of this utility model:

[0040] In use, staff walk to the riverbank where water quality analysis is required, and then adjust the position of the lifting shell 5 according to the amount of water to be taken. Then, pull the pull block 82 to compress the spring 83 in the limiting slide groove 81. When the pull block 82 drives the plug rod 84 to disengage from the plug hole 18, the rotating ring 17 rotates to drive the second transmission wheel 15 to rotate. The second transmission wheel 15 drives the first transmission wheel 14 to rotate through the transmission belt 16. The rotation of the first transmission wheel 14 drives the rotating rod 7 to rotate. The rotation of the rotating rod 7 drives the gear 11 to mesh with the teeth 10. At this time, the lifting shell 5 can be lowered. When the lifting shell 5 is lowered to the appropriate position, the pull block 82 is released. The spring 83 will undergo elastic deformation, causing the plug rod 84 on the pull block 82 to insert into the plug hole 18. At this time, the position of the rotating ring 17 can be fixed. The rotating ring 17 can fix the position of the gear 11 together through the first transmission wheel 14, the second transmission wheel 15 and the transmission belt 16. At this time, the gear 11 can fix the position of the lifting shell 5.

[0041] In summary, this water sampling device for water quality analysis and testing, through the coordinated use of the handle 4, lifting shell 5, mating groove 6, rotating rod 7, and positioning component 8, achieves the following: the rotation of the first transmission wheel 14 drives the rotating rod 7 to rotate, which in turn drives the gear 11 to mesh with the teeth 10, thereby causing the lifting shell 5 to descend. This solves the problem that while water sampling devices are designed for convenient extraction of water from rivers, the containers on these devices are limited to a specific capacity, requiring multiple extractions when more water needs to be collected for analysis, which is quite cumbersome.
