[0040] Example:
[0041] The following is in conjunction with the appendix Figure 1-3The present invention will be described in further detail below.
[0042] Please see Figure 1-3 This utility model provides a technical solution: a groundwater quality sampling device for water conservancy testing, including a fixed plate 1. A winding assembly 2 is fixedly connected to the upper surface of the fixed plate 1. The winding assembly 2 includes two support plates 201, a first rotating shaft 202, a winding roller 203, a transmission line 204, and a scale line 205. A through hole 3 is opened on the surface of the fixed plate 1. A limit assembly 4 is provided on the side of the winding assembly 2. The limit assembly 4 includes a square slide rod 401, a handle 402, a limit tooth 403, and a limit wheel 404. A rotating block 5 is fixedly connected to the lower surface of the fixed plate 1. A support leg 6 is rotatably connected to the surface of the rotating block 5. A stop block 7 is fixedly connected to the surface of the rotating block 5. There are multiple sets of support legs 6, which are evenly distributed on the lower surface of the fixed plate 1. A sampling bucket 8 is fixedly connected to the lower end of the transmission line 204. A horizontal partition 9 and a vertical partition 10 are fixedly connected to the inner wall of the sampling bucket 8. The vertical partition 10 is fixedly connected to the lower surface of the horizontal partition 9. Sampling... The inner wall of the sampling barrel 8 is provided with multiple sampling components 11. Each sampling component 11 includes a second rotating shaft 1101, a threaded column 1102, a threaded tube 1103, a piston 1104, a rotating handle 1105, a first gear 1106, and an exhaust port 1107. A transmission component 12 is provided on the surface of the transverse partition 9. The transmission component 12 includes a turntable 1201, a first motor 1202, a second motor 1203, and a second gear 1204. Multiple connecting pipes 13 are fixedly connected to the lower surface of the sampling barrel 8. By setting the transverse partition 9 and the vertical partition 10, the inner wall of the sampling barrel 8 can be divided into multiple cavities. By setting the sampling components 11, the threaded column 1102 drives the threaded tube 1103 and the piston 1104 to move up and down, which facilitates the extraction of groundwater through the connecting pipes 13 and its separate storage. By setting multiple support legs 6 and multiple rotating blocks 5, the fixed plate 1 can be supported.
[0043] Specifically, both support plates 201 are fixedly connected to the upper surface of the fixed plate 1.

The transmission line 204 is wound and connected to the surface of the take-up roller 203. One end of the transmission line 204 passes through the through hole 3. The scale line 205 is set on the surface of the transmission line 204.
[0044] By adopting the above technical solution, and by setting up the transmission line 204 and the scale line 205, it is convenient to accurately observe the descent depth of the sampling bucket 8, and to accurately sample groundwater at a specified depth. By setting up the winding roller 203, it is convenient to wind up and unwind the transmission line 204.
[0045] Specifically, the square slide bar 401 is slidably connected to one end of the first rotating shaft 202, the handle 402 is fixedly connected to the other end of the square slide bar 401, the limiting tooth 403 is fixedly connected to the surface of the handle 402, and the limiting wheel 404 is fixedly connected to the side of one of the support plates 201.
[0046] By adopting the above technical solution, by setting a handle 402, it is easy to drive the first rotating shaft 202 and the take-up roller 203 to rotate. By setting a square slide bar 401, it is easy to drive the handle 402 and the limiting tooth 403 to move, so that the limiting tooth 403 is engaged with the surface of the limiting wheel 404, thereby limiting the rotation of the take-up roller 203.
[0047] Specifically, the second rotating shaft 1101 is rotatably connected to the surface of the sampling barrel 8 and the surface of the horizontal partition 9 via a bearing. The threaded column 1102 is fixedly connected to the lower end of the second rotating shaft 1101. The threaded tube 1103 is threadedly connected to the surface of the threaded column 1102. The piston 1104 is fixedly connected to the lower end of the threaded tube 1103. The piston 1104 is slidably connected to the surface of the vertical partition 10 and the inner wall of the sampling barrel 8. The rotating handle 1105 is fixedly connected to the upper end of the second rotating shaft 1101. The first gear 1106 passes through the surface of the second rotating shaft 1101. The exhaust hole 1107 is opened on the surface of the sampling barrel 8.
[0048] By adopting the above technical solution, the rotation of the second rotating shaft 1101 drives the threaded column 1102 to rotate on the inner wall of the threaded tube 1103, causing the piston 1104 to move up and down, thereby facilitating the extraction and separate storage of groundwater through the connecting pipe 13.
[0049] Specifically, turntable 1201 is rotatably connected to the surface of partition 9 via bearings, first motor 1202 is fixedly connected to the lower surface of turntable 1201, one end of the output shaft of first motor 1202 is fixedly connected to the lower surface of turntable 1201, second motor 1203 is fixedly connected to the upper surface of turntable 1201, and second gear 1204 is fixedly connected to the upper end of the output shaft of second motor 1203.
[0050] By adopting the above technical solution, the second motor 1203 operates, thereby driving the second gear 1204 to rotate. Under the meshing relationship between the first gear 1106 and the second gear 1204, the second motor 1203 drives the second rotating shaft 1101 to rotate. The first motor 1202 operates, thereby driving the turntable 1201 to rotate. This facilitates the second motor 1203 and the second gear 1204 to mesh with multiple first gears 1106 respectively, so as to sample groundwater at different depths.
[0051] Specifically, the sampling bucket 8 has multiple legs 14 fixedly connected to its lower surface, and the lower ends of the multiple support legs 6 are all provided with conical surfaces.
[0052] By adopting the above technical solution and setting the support legs 14, it is easy to support the sampling bucket 8, thereby facilitating the release of groundwater through the connecting pipe 13.
[0053] The working principle of this utility model is as follows: In use, the fixing plate 1 is placed above the well, supported by multiple rotating blocks 5 and support legs 6. The support angle of the support legs 6 is limited by the stop block 7. The sampling bucket 8 is placed inside the well. By pulling the handle 402, the limiting tooth 403 disengages from the limiting wheel 404, releasing the limitation on the winding roller 203. The handle 402 drives the winding roller 203 to rotate, releasing the transmission line 204. The descent depth of the sampling bucket 8 is accurately observed under the action of the scale line 205. When the sampling bucket 8 descends to the designated depth, the handle 402 and the limiting tooth 403 move via the square slide rod 401, causing the limiting tooth 403 to engage with the surface of the limiting wheel 404, limiting the rotation of the winding roller 203. The first motor 1202 then operates, driving the turntable. Rotation of 1201 drives the second motor 1203 and the second gear 1204 to mesh with one of the first gears 1106. The operation of the second motor 1203 drives the second gear 1204 to rotate. Under the meshing relationship between the first gear 1106 and the second gear 1204, the second motor 1203 drives the second rotating shaft 1101 to rotate, causing the threaded column 1102 to rotate on the inner wall of the threaded tube 1103, causing the piston 1104 to move up and down. Groundwater is extracted through the connecting pipe 13 and stored separately. By repeating the above steps, groundwater at different depths is extracted. Then, the sampling bucket 8 is pulled out of the well. When it is necessary to release the sample water, the handle 1105 can be rotated to drive the piston 1104 to move downward, releasing the sample water through the connecting pipe 13 for water quality testing.
[0054] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
