Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a layered sampler for detecting the heavy metal content of wastewater. Background Technique

[0002] When sampling and detecting heavy metals in scenarios such as sewage pipelines, rivers, and lakes, it is necessary to separately take water samples at different depths for sampling and detection (i.e., layered sampling and detection) to ensure the authenticity, objectivity, and representativeness of the detection results.

[0003] Currently, the samplers used in the sampling of wastewater heavy metal detection are relatively simple and have relatively single functions. When conducting layered sampling of heavy metal-containing water samples, manual control is required. Affected by factors such as the depth of the sewage well in the on-site pipeline network, the water flow velocity, and the light, the manual control of layered sampling operation has problems such as large operation difficulty and poor accuracy. Therefore, there is an urgent need for a device that can achieve layered sampling for heavy metal wastewater. Content of the Utility Model

[0024] Refer to Figures 1 to 5, in the embodiment of the present utility model, a layered sampler for detecting the heavy metal content of wastewater includes a bearing plate 1, a fixing plate 3, a connecting block 4, an observation plate 5, a sliding rod 15, a measuring component, a sampling component, and a fixing component; the fixing plate 3 is fixedly connected to the bearing plate 1, the connecting block 4 is fixedly connected to the fixing plate 3, the observation plate 5 is fixedly connected to the connecting block 4, a sliding installation hole 14 is provided in the connecting block 4, the sliding rod 15 is slidably installed in the sliding installation hole 14, a first sliding block 7 is slidably connected to the fixing plate 3, a second sliding block 8 is slidably connected to the observation plate 5, a connecting rod 9 is fixedly connected between the first sliding block 7 and the second sliding block 8, and the connecting rod 9, the fixing plate 3, and the observation plate 5 have the same length; the measuring component is connected between the second sliding block 8 and the observation plate 5 and is used to detect the relative position between the second sliding block 8 and the observation plate 5; the sampling component is connected between the bottom of the sliding rod 15 and the first sliding block 7, and when the sampling component moves to the first sliding block 7, the sampling component opens, thereby completing the sampling of the wastewater; the fixing component is connected to the second sliding block 8 and is used to detect the relative position between the second sliding block 8 and the observation plate 5. First, the present utility model inserts the device into the bottom of the pool, so that the bearing plate 1 is attached to the bottom of the pool. Only when the staff controls the second sliding block 8 to slide and adjust on the observation plate 5, the second sliding block 8 drives the first sliding block 7 to move synchronously through the connecting rod 9, so that the second sliding block 8 is level with the water surface. At this time, the relative position of the second sliding block 8 can be observed through the measuring component. Then, the second sliding block 8 is moved according to the observation result, and the second sliding block 8 drives the first sliding block 7 to be inserted synchronously through the connecting rod 9. At this time, the depth of the second sliding block 8 from the water surface can be measured by observing the moving distance of the first sliding block 7. When the second sliding block 8 moves to the preset collection depth, the relative position between the second sliding block 8 and the observation plate 5 is relatively fixed through the fixing component, and then the sampling component can be installed at the bottom of the sliding rod 15. Then, the sampling component is driven to press down through the sliding rod 15. When the sampling component touches the second slider, the sampling component is opened, and at this time, the water body of this layer enters the sampling component to complete the sampling.

[0025] In one case of this embodiment, please refer to Figures 1 to 5 , a handle 25 is rotatably connected to the top of the observation plate 5. The present utility model takes and places the device through the setting of the handle 25.

[0026] In one case of this embodiment, please refer to Figures 1 to 5 , positioning nails 2 are fixedly connected to the bottom of the bearing plate. The present utility model inserts the positioning nails 2 into the bottom of the pool and positions the device through the positioning nails 2 to prevent the device from tilting.

[0028] In one case of this embodiment, please refer to Figures 1 to 5 , the sampling component includes a threaded mounting cylinder 19 fixedly connected to the bottom of the sliding rod 15. A threaded mounting head 20 is threadedly connected inside the threaded mounting cylinder 19. A sampling bucket 21 is fixedly connected to the threaded mounting head 20. A liquid inlet 22 is provided at one end of the sampling bucket 21 away from the threaded mounting head 20. A one-way valve 23 is installed in the liquid inlet 22.

A mounting seat 17 is fixedly connected to the second slider 8. A push rod 18 is fixedly connected to the mounting seat 17. The push rod 18 cooperates with the one-way valve 23. First, the handle 16 is used to drive the sliding rod 15 to slide telescopically inside the connecting block 4, so as to adjust the relative position of the bottom of the sliding rod 15. During the sampling process, first, the threaded mounting head 20 on the sampling bucket 21 is threadedly mounted into the threaded mounting cylinder 19, so as to mount the sampling bucket 21 on the sliding rod 15. After that, when the depth of the device is adjusted, then the handle 16 is controlled to drive the sliding rod 15 to press down. The sliding rod 15 drives the sampling bucket 21 to approach the push rod 18, and then the one-way valve 23 is pushed open by the push rod 18, so as to open the liquid inlet 22. After that, the gas in the sampling bucket 21 is discharged along the exhaust port 24, and the water body enters the sampling bucket 21 along the liquid inlet 22. Then, the sampling bucket 21 is driven away from the push rod 18. At this time, the one-way valve 23 closes, thus completing the sampling of the water body.

[0029] In one case of this embodiment, please refer to Figures 1 to 5 , the fixing component includes a mounting frame 11 fixedly connected to the second slider 8. A threaded cylinder 12 is fixedly connected inside the mounting frame 11. A hand-tightening bolt 13 is threadedly connected inside the threaded cylinder 12. The hand-tightening bolt 13 cooperates with the observation board 5. The fixing component converts the rotary motion of the hand-tightening bolt 13 into a linear motion of the hand-tightening bolt 13 by screwing the hand-tightening bolt 13 and through the threaded connection between the hand-tightening bolt 13 and the threaded cylinder 12, so as to relatively clamp and fix with the observation board 5 through the linear motion of the hand-tightening bolt 13, and then relatively fix between the second slider 8 and the observation board 5.
