The main design purpose of this device is to collect water samples in water bodies at different depths to obtain comprehensive data on the vertical profile of the water body, so as to more accurately assess the water quality status. It involves collecting water samples at different water depths. This sampling method is of great significance for understanding the overall status of the water body, changes in water quality, and the distribution of pollutants. By analyzing these data, we can understand the overall quality status of the water body, the types and concentration distribution of pollutants, etc. This information is of great reference value for formulating environmental protection measures, water pollution control plans, and water resource management strategies.

[0003] However, in actual applications, some water quality multi-depth sampling devices have a problem. When collecting samples, traditional water quality sampling devices can only collect samples one at a time, and cannot collect multiple samples at a time, resulting in low efficiency and increased sampling costs. At the same time, the collected samples are not convenient to take out as a whole, which also brings inconvenience to subsequent analysis and testing.

[0004] Therefore, there is an urgent need to improve a multi-depth sampling device for water quality used in environmental monitoring to solve the above-mentioned problems. Utility Model Content

The utility model can collect multiple samples at one time when sampling water quality through the arrangement of a motor, a fixing frame, a fixing frame, a sampling tube, a supporting frame, a threaded rod, a threaded sleeve, and a water delivery mechanism, which greatly improves the efficiency of collection. After collecting multiple samples, the threaded rod can be rotated to move outward under the action of the thread, so that the threaded rod is separated from the inside of the threaded hole and no longer limits the fixing frame, and the fixing frame is pulled out upward, so that multiple samples in multiple sampling tubes can be taken out as a whole, which is convenient for subsequent detection and analysis.

DETAILED DESCRIPTION

[0021] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0022] like Figure 1-Figure 5 As shown, the multi-depth sampling device for environmental monitoring water quality provided in this embodiment includes a lift 1, which is characterized in that: one end of the lift 1 is fixedly connected to a shell 2, a base 3 is movably installed at the bottom of the shell 2, a motor 5 is fixedly installed inside the base 3, and a support frame 6 is connected to the output end of the motor 5. A fixing frame 7 is movably installed on the surface of the support frame 6, and a plurality of fixing frames 8 are fixedly installed on the surface of the fixing frame 7, a sampling tube 9 is installed inside the fixing frame 8, a threaded sleeve 10 is installed on the surface of the fixing frame 7, a threaded hole is opened on the surface of the support frame 6, and a threaded rod 11 is screwed together with the thread inside the threaded hole, and a water delivery mechanism 12 is arranged inside the shell 2.

[0023] In this embodiment, when sampling water quality, the shell 2 and the base 3 can be controlled by the lift 1 to move up and down to a suitable depth as needed. When adjusted to a suitable depth, the water quality sample is transported to the inside of one of the sampling tubes 9 through the water delivery mechanism 12. After the water quality sampling of the depth is completed, the motor 5 is started to drive the support frame 6 to rotate, and the support frame 6 drives the fixed frame 8 to rotate, so that the adjacent sampling tube 9 rotates to the bottom of the outlet pipe 15, so as to facilitate the collection and sampling of water quality samples at other depths. By repeating this cycle, multiple samples can be collected at one time, which greatly improves the collection efficiency and reduces the collection cost. After collecting multiple samples, the threaded rod 11 can be rotated to move outward under the action of the thread, so that the threaded rod 11 is disengaged from the threaded hole and no longer limits the fixing frame 7, and the fixing frame 7 is pulled out upward, so as to facilitate the overall removal of multiple samples in multiple sampling tubes 9, which is convenient for subsequent detection and analysis.

[0024] like Figure 2-Figure 4 As shown, the water delivery mechanism 12 includes a water pump 13 fixedly mounted on the inner wall of the housing 2 , the input end of the water pump 13 is connected to a filter box 14 , and the output end of the water pump 13 is connected to a water outlet pipe 15 .

[0025] In this embodiment, when it is necessary to collect water quality, water can be pumped by the water pump 13, and the pumped water is transported to the inside of the sampling tube 9 through the outlet pipe 15. The particles and impurities in the water quality can be filtered through the filter box 14 to prevent the water pump 13 from being blocked.

[0026] like Figure 2-Figure 3As shown, two slots 16 are symmetrically provided at the bottom of the shell 2, a plug block 17 adapted to the shell 2 is fixedly installed on the top of the base 3, and plug holes 18 are provided on the surfaces of the two plug blocks 17, a sealing ring 4 is installed between the shell 2 and the base 3, and fixed cylinders 19 are fixedly installed on both sides of the shell 2. A latch 20 that can be movably inserted into the plug hole 18 is arranged inside the fixed cylinder 19, and a first spring 27 is sleeved on the surface of the latch 20, and the two ends of the first spring 27 are respectively connected to the inner wall of the fixed cylinder 19 and the surface of the latch 20.

[0027] In this embodiment, when sampling is completed, the latch 20 is pulled outward until the latch 20 is out of the socket 18 and is no longer limited and fixed, so that the latch 20 will squeeze the first spring 27 to shrink while moving outward, and the base 3 is pulled out downward to facilitate the removal of the internal sampling tube 9. After removal, the base 3 can be quickly inserted into the slot 16 in the shell 2 through the plug block 17, and the latch 20 is released at the same time. The first spring 27 is used to rebound to the inside of the socket 18 and limit and fix it again. The slot 16, the plug block 17, the fixing tube 19, the latch 20, and the first spring 27 are arranged to facilitate the installation and disassembly of the shell 2 and the base 3. The sealing ring 4 can fill the gap between the base 3 and the shell 2 to prevent water from penetrating into the interior through the gap, making it more airtight.

[0028] like Figure 2-Figure 5 As shown, a push rod 21 is movably inserted inside the fixed frame 8, one end of the push rod 21 is fixedly connected to the first clamping plate 22, the other end of the push rod 21 is fixedly installed with a stop block 23, a second spring 24 is sleeved on the surface of the push rod 21, the two ends of the second spring 24 are respectively connected to the fixed frame 8 and the first clamping plate 22, and a second clamping plate 25 is fixedly installed on one side of the inner wall of the fixed frame 8.

[0029] In this embodiment, when sampling water quality, it may be necessary to replace the sampling tube 9 of different capacity according to the situation. When replacement is needed, the push rod 21 is pulled to drive the first clamp 22 to move outward, and the second spring 24 is squeezed to shrink it. The first clamp 22 moves outward away from the sampling tube 9 and no longer fixes it. At the same time, the sampling tube 9 of other calibers is taken out and replaced, and the new sampling tube 9 is placed inside the fixed frame 8. At the same time, the push rod 21 is released and the resilience of the second spring 24 is used to drive the first clamp 22 to move inward until it contacts the sampling tube 9. The first clamp 22 pushes the sampling tube 9 to move and resist against the second clamp 25. The first clamp 22 and the second clamp 25 are clamped to prevent shaking during sampling. By replacing the sampling tubes 9 of different calibers, various sampling needs can be flexibly adapted.

[0030] like Figure 4-Figure 5 As shown, a pull ring 26 is fixedly installed on the top of the fixing frame 7, and a turning handle 28 is fixedly installed on one end of the threaded rod 11.

[0031] In this embodiment, the pull ring 26 is provided to facilitate the extraction of the fixing bracket 7, and the turning handle 28 is provided to make it easier to rotate the threaded rod 11 by hand, making the operation more convenient and labor-saving.

[0032] like Figure 1-Figure 5 As shown, the principle of the multi-depth sampling device for environmental monitoring water quality provided by this embodiment is as follows: when sampling water quality, the lift 1 can control the shell 2 and the base 3 to move up and down to a suitable depth according to needs. When adjusted to a suitable depth, water can be pumped by the water pump 13, and the pumped water is transported to the inside of one of the sampling tubes 9 through the outlet pipe 15. After the water quality sampling of the depth is completed, the motor 5 is started to drive the support frame 6 to rotate, and the support frame 6 drives the fixed frame 8 to rotate, so that the adjacent sampling tube 9 rotates to the bottom of the outlet pipe 15, so as to facilitate the collection and sampling of water quality samples at other depths. Through such a cycle, multiple samples can be collected at one time, which greatly improves the efficiency of collection and reduces the cost of collection. After the collection of multiple samples is completed, the threaded rod 11 can be rotated to move outward under the action of the thread, so that the threaded rod 11 is disengaged from the inside of the threaded hole and no longer limits the fixing frame 7, and the fixing frame 7 is pulled out upward, so as to facilitate the overall removal of multiple samples in multiple sampling tubes 9, which is convenient for subsequent detection and analysis.
