Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, specifically to a surface stratified water sampling device for ecological environment monitoring. Background Technology

[0002] In the field of ecological and environmental monitoring, the analysis of surface water quality relies on sampling data from water bodies at different depths. Parameters such as dissolved oxygen content, pollutant concentration, and pH value vary significantly at different water depths. Collecting only surface water or water samples at fixed depths cannot fully reflect the true pollution status and ecological environment quality of the water body. Therefore, stratified water sampling devices have become key monitoring equipment.

[0003] A natural water sampling device with stratified sampling function, patent publication number CN221781944U, achieves simultaneous sampling of water bodies at different depths by setting several sampling boxes on a sleeve pole. This solves to some extent the problem of low efficiency in traditional single sampling, which can only obtain water samples from a single depth, and meets the basic requirements of batch sampling. However, this device has significant technical limitations. Its sampling boxes are all fixedly installed at preset positions on the sleeve pole, and the sampling depth cannot be flexibly adjusted according to the actual monitoring scenario. It is difficult to adapt to complex and ever-changing surface water monitoring scenarios. Therefore, there is an urgent need for a surface stratified water sampling device for ecological environment monitoring. Utility Model Content

[0019] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] like Figures 1-6 As shown, this specific implementation adopts the following technical solution, which includes a sampling cylinder 1, a flip cover 2, and a sealing plug 3. Several sampling cylinders 1 are abutted by flip covers 2 on their upper parts. A sealing plug 3 is inserted into the drain hole of the sampling cylinder 1. A sealing ring 16 is fixedly installed in the annular groove opened at the bottom of the flip cover 2, and the sealing ring 16 is abutted against the upper part of the sampling cylinder 1. The sealing ring 16 can improve the sealing performance of the gap between the flip cover 2 and the sampling cylinder 1, and prevent water from seeping in through the gap between the flip cover 2 and the sampling cylinder 1 when the sampling cylinder 1 has not reached the specified depth. It also includes: There are two vertical rods 4, which are respectively suspended on the left and right sides of several sampling cylinders 1. Several lifting blocks 5 are movably sleeved on the vertical rods 4. The lifting blocks 5 are fixedly set on the sampling cylinders 1. The left lifting block 5 is provided with a positioning mechanism 6 connected to the vertical rod 4. The left vertical rod 4 is provided with a scale line 14. The upper part of the left lifting block 5 is provided with a reference point 15 that cooperates with the scale line 14. The cooperation between the scale line 14 and the reference point 15 is used to accurately determine the adjustment height of the lifting block 5 and the sampling cylinder 1. Fixed block 7, there are several fixed blocks 7, which are respectively fixedly installed on the upper part of several lifting blocks on the right side. Two flip blocks 8 are fixedly installed on the flip cover 2, and the two flip blocks 8 are respectively movably installed on the front and rear sides of the fixed block 7. A rotating rod 9 is rotatably installed in the fixed block 7 through the bearing, and the end of the rotating rod 9 is fixedly connected to the flip block 8. Connecting plate 10, there are two connecting plates 10, which are respectively fixedly installed at the upper and lower ends of the left and right vertical rods 4. The right vertical rod 4 is provided with a synchronous control mechanism 11 connected to the fixing block 7, and the upper connecting plate 10 is fixedly provided with a connecting frame 12. The positioning mechanism 6 includes: An arc-shaped contact plate 6-1 is movably disposed within the lifting block 5 on the left side. Two springs 6-2 connected to the arc-shaped contact plate 6-1 are fixedly disposed within the lifting block 5 on the left side. A rubber pad 13 is fixedly disposed on the inner arc wall of the arc-shaped contact plate 6-1, and the rubber pad 13 is in contact with the vertical rod 4 on the left side. The rubber pad 13 can increase the friction between the arc-shaped contact plate 6-1 and the vertical rod 4 on the left side, so that the height of the sampling cylinder 1 can be guaranteed. There are four crossbars 6-3, all of which are fixedly installed on the arc-shaped contact plate 6-1. One end of each of the four crossbars 6-3 passes through the lifting block 5 on the left and is fixedly connected to the pressing plate 6-4. The positioning mechanism 6 can be used to position several sampling tubes 1 at different heights, so as to facilitate sampling of water at a specified depth according to sampling requirements. The synchronization control mechanism 11 includes: A bidirectional lead screw 11-1 is rotatably inserted into the right vertical rod 4 via a bearing. The upper end of the bidirectional lead screw 11-1 passes through the upper connecting plate 10 and is fixedly provided with an adjustment handle 11-2. Two polygonal blocks 11-3 are movably provided in the right vertical rod 4, and the polygonal blocks 11-3 are rotatably sleeved on the bidirectional lead screw 11-1 via a thread. A connecting rod 11-4 is hinged to the polygonal blocks 11-3. The extrusion strip 11-5 is movably disposed in the strip-shaped groove opened on the right vertical rod 4, and one end of the connecting rod 11-4 is hinged to the extrusion strip 11-5; Gears 11-6, there are several gears 11-6, which are fixedly sleeved on several rotating rods 9 respectively. A rack 11-7 is movably inserted in the fixing block 7. The rack 11-7 is meshed with the gears 11-6. One end of the rack 11-7 is in contact with the extrusion strip 11-5. Torsion springs 11-8 connected to the inner wall of the fixing block 7 are fixedly installed on both sides of the gears 11-6. The synchronous control mechanism 11 can realize the flipping and opening of several flip covers 2, thereby realizing the synchronous sampling of several sampling cylinders 1.

[0021] When using this utility model, the connecting frame 12 is fixed to the hull or other positions, so that the two vertical rods 4 and several sampling cylinders 1 are submerged in the water. Then, the adjusting handle 11-2 is rotated, which drives the bidirectional screw 11-1 to rotate, so that the two polygonal blocks 11-3 move synchronously in opposite directions. With the cooperation of the connecting rod 11-4, the extrusion strip 11-5 can be moved to the outside of the strip groove. The extrusion strip 11-5 pushes the rack 11-7 to move. The rack 11-7 drives the rotating rod 9 to rotate through the gear 11-6. The rotating rod 9 drives the flip cover 2 to flip upward through the flip block 8 to open the sampling cylinder 1, so that several sampling cylinders 1 can be sampled synchronously at different water depths. Then, the adjusting handle 11-2 is rotated in the opposite direction so that the flip cover 2 closes the sampling cylinder 1. After that, the vertical rods 4 and the sampling cylinder 1 are taken out of the water. Then, the sealing plug 3 is taken out from the drain hole so that the water sample in the sampling cylinder 1 flows out from the drain hole. If the sampling cylinder 1 is to sample water at different depths, the pressing plate 6-4 can be pushed towards the lifting block 5. The pressing plate 6-4 drives the arc-shaped contact plate 6-1 to detach from the vertical rod 4 through the cross bar 6-3 and compresses the spring 6-2. Then the height of the lifting block 5 on the vertical rod 4 can be adjusted. Then the pressing plate 6-4 is released, so that the spring 6-2 extends and pushes the arc-shaped contact plate 6-1 to move, so that the arc-shaped contact plate 6-1 abuts against the vertical rod 4 and generates a huge friction force between them, so as to limit the height of the sampling cylinder 1.

[0022] Compared with the prior art, the beneficial effects of this specific embodiment are as follows: 1. With the cooperation of the sealing ring 16, the sealing between the flip cover 2 and the sampling tube 1 can be effectively enhanced, preventing water from seeping into the gap between the two when the sampling tube 1 has not reached the specified depth, preventing the water from being mixed into the non-target depth water in advance, ensuring that the water sample collected is only the water at the specified depth, significantly improving the accuracy of stratified sampling, and providing a pure target water sample for subsequent water quality parameter analysis. 2. With the help of the scale line 14 on the left vertical rod 4 and the reference point 15 on the upper part of the lifting block 5, the adjustment height of the sampling tube 1 can be judged intuitively and accurately. At the same time, the arc-shaped contact plate 6-1 in the positioning mechanism 6 abuts against the vertical rod 4 under the action of the spring 6-2, and the rubber pad 13 increases the friction force, which can realize the stable positioning of the sampling tube 1 at different heights. This not only solves the problem of fixed sampling depth of the existing device, but also can accurately adjust to the target depth and maintain stability, meeting the collection needs of water samples at specific depths in different monitoring scenarios. 3. Through the cooperation of the bidirectional lead screw 11-1, polygonal block 11-3, connecting rod 11-4, extrusion bar 11-5, rack 11-7 and gear 11-6 in the synchronous control mechanism 11, rotating the adjustment handle 11-2 can drive all the flip covers 2 to flip open or close synchronously, so that multiple sampling cylinders 1 at different depths can complete the water sampling action simultaneously. There is no need to operate the sampling components one by one, which greatly reduces the sampling operation time and improves the overall efficiency of stratified sampling. It is especially suitable for monitoring scenarios that require batch collection of water samples at multiple depths. 4. When adjusting the height of sampling cylinder 1, push the pressing plate 6-4 to release the positioning. After adjustment, release the pressing plate 6-4 to automatically reset the positioning. The overall operation steps are simple and easy to understand, reducing the operation difficulty for monitoring personnel and improving the convenience of on-site monitoring.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
