Description

Technical Field

[0001] This utility model relates to the field of water quality sampling technology, and in particular to an emergency multi-depth water quality sampling device. Background Technology

[0002] Emergency multi-depth water sampling equipment is a crucial tool for obtaining water samples at different depths in response to sudden environmental pollution incidents, disasters, or routine monitoring. With the increasing importance of water quality monitoring in water resource management, environmental protection, and water pollution prevention, this equipment, through efficient automated control, can be rapidly deployed and accurately collect water samples at various depths, providing real-time data support, especially when the aquatic environment changes. The equipment is widely used in routine water quality monitoring and research, covering deep water quality analysis in rivers, lakes, reservoirs, and oceans. Its core advantages lie in its efficiency, reliability, and adaptability, enhancing environmental disaster early warning and monitoring capabilities. This review will discuss the design principles, current development status, and challenges of this equipment, and will also look ahead to future technological innovations and application trends.

[0003] A search revealed an existing patent (publication number: CN212007924U) that discloses a river water quality sampling device, including a mounting base. The upper outer surface of the mounting base has a mounting hole near a corner. A support frame is positioned on the upper outer surface of the mounting base near the mounting hole. A bearing is mounted on the upper end of the support frame, and a winch is mounted inside the bearing. A connecting plate is positioned on the upper outer surface of the mounting base near the support frame, and a telescopic rod is mounted on the upper outer surface of the connecting plate. This utility model's river water quality sampling device, by incorporating a telescopic rod, increases the sampling range, allowing for the collection of more samples. The connecting plate and threaded hole, along with bolts, facilitate the installation and disassembly of the telescopic rod from the mounting base, making it easy to carry.

[0004] However, in actual use, the above-mentioned solution involves directly lowering the sampling bucket into the water via a cable to collect samples, and only one water layer can be sampled at a time. This necessitates repeated equipment adjustments during operation, increasing time costs and making it unsuitable for rapid response in emergency scenarios. Furthermore, due to its reliance on manual operation, the sampling location may be affected by external factors such as water flow and wind, leading to unstable sampling and jeopardizing data accuracy.

[0005] Therefore, this utility model provides an emergency multi-depth water quality sampling device. Utility Model Content

[0006] The purpose of this invention is to solve the problem that existing technologies can only sample water from one water layer at a time, which leads to repeated equipment adjustments during operation, increases time costs, and is not suitable for rapid response in emergency scenarios. Therefore, this invention proposes an emergency multi-depth water quality sampling device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An emergency multi-depth water quality sampling device includes a sampling vessel and also includes:

[0009] The first through hole is located at the top of the middle section of the collection vessel;

[0010] The lifting components are symmetrically arranged on both sides of the top of the first through hole;

[0011] The counterweight is located on the lifting end of the lifting assembly on one side;

[0012] The sampling component is located on the lifting end of the lifting component on the other side;

[0013] The control component is located inside the sampling component;

[0014] The connecting components are symmetrically positioned outside the sampling components.

[0015] As a preferred technical solution of this application, the lifting assembly includes support rods symmetrically fixed to the top wall of the collection vessel and located on both sides of the first through hole. A winch is fixedly connected to some side walls of the support rods, and a winch rope is fixedly connected to the output end of one side of the winch. The winch rope is fixedly connected to a counterweight.

[0016] As a preferred technical solution of this application, the sampling component includes a hook detachably connected to the bottom of a rope away from the counterweight. A collection bucket is fixedly connected to the bottom of the hook. Four water storage chambers are provided inside the collection bucket. A first filter screen is fixedly connected to the inner wall of the top end of the water storage chamber. A water inlet is fixedly connected to the inner wall of the bottom end of the first filter screen. A second filter screen is fixedly connected to the inner side of the water inlet. A float is slidably connected to the inner side of the middle section of the water storage chamber.

[0017] As a preferred technical solution of this application, the control component includes a motor fixed inside the bottom side of the collection bucket, a rotating disk rotatably connected to the bottom inner side of the collection bucket, the output end of the motor being fixedly connected to the rotating disk, and a second through hole being opened on one side of the top of the rotating disk.

[0018] As a preferred technical solution of this application, the connecting component includes a fixing ring symmetrically fixed to the outer wall of the collection bucket, a shackle fixedly connected to the outer side of the fixing ring, and the shackle being slidably connected to a rope near the counterweight.

[0019] As a preferred technical solution of this application, a rubber layer is provided on the outer side of the counterweight.

[0020] Compared with the prior art, this utility model provides an emergency multi-depth water quality sampling device, which has the following beneficial effects:

[0021] 1. The emergency multi-depth water quality sampling device of this utility model uses a motor to drive a rotating disk and a second through hole to rotate synchronously. The second through hole connects different water storage tanks to the outside world, allowing external water to enter the water storage tanks through a second filter, inlet, and second through hole. Simultaneously, a float can rise, thus extracting external water and completing the sampling. Afterwards, the rotating disk drives the second through hole to rotate and seal the water storage tank, allowing sampling to continue to the next water layer. This achieves multi-level water quality sampling, automates and improves sampling efficiency, reduces manual intervention, is suitable for emergency monitoring, precisely controls the through hole rotation to ensure data accuracy, automatically seals the water storage tanks after sampling to avoid cross-contamination, adapts to complex aquatic environments, and quickly and accurately collects data from different water layers, meeting the needs of emergency water quality monitoring.

[0022] 2. The emergency multi-depth water quality sampling device of this utility model, before sampling, first places a counterweight at the bottom of the water. Through cooperation with the winch rope, the sampling component uses an external connecting component to cooperate with the winch rope, thereby fixing the sampling path. The sampling component slides along the winch rope using the connecting component, enhancing the stability of the device, avoiding positional deviation caused by water flow interference, ensuring accurate sampling path, and the precise control of the depth and position of the device by the cooperation of the winch rope and connecting component, improving sampling accuracy. In addition, this design can operate stably in complex water environments, reduce adjustment time, improve sampling efficiency, and is particularly suitable for rapid sampling in emergency situations.

Example

[0032] Reference Figure 1-6 An emergency multi-depth water quality sampling device, including a sampling vessel 1, and also including:

[0033] The first through hole 15 is located at the top of the middle section of the collection vessel 1;

[0034] The lifting components are symmetrically arranged on both sides of the top of the first through hole 15, and the lifting components on both sides are simultaneously supported and limited by the collection vessel 1.

[0035] The counterweight 14 is mounted on the lifting end of the lifting assembly on one side, and the lifting assembly on one side drives the counterweight 14 to move up and down.

[0036] The sampling component is located on the lifting end of the lifting component on the other side, and the lifting component on the other side drives the sampling component to move up and down;

[0037] A control component is located inside the sampling component, and the water inlet of the sampling component is controlled by the control component;

[0038] The connecting component is symmetrically arranged on the outside of the sampling component, and connects the sampling component and the lifting component near the counterweight 14 through the connecting component.

[0039] The lifting assembly includes symmetrical support rods 11 fixed to the top wall of the collection vessel 1 and located on both sides of the first through hole 15. The collection vessel 1 supports and fixes the support rods 11 on both sides. A winch 12 is fixedly connected to the side wall of the support rods 11. The winch 12 is supported and fixed by the support rods 11. A winch rope 13 is fixedly connected to the output end of one winch 12. The winch 12 is used to wind and unwind the winch rope 13. The winch rope 13 is fixedly connected to the counterweight 14. The counterweight 14 is supported and fixed by the winch rope 13.

[0040] The sampling assembly includes a hook 23 detachably connected to the bottom of a rope 13 on the side away from the counterweight 14. The hook 23 is locked in place by the rope 13 on the side away from the counterweight 14. A collection bucket 2 is fixedly connected to the bottom of the hook 23, and the collection bucket 2 is supported and fixed by the hook 23. Four water storage chambers 25 are provided inside the collection bucket 2. Water samples of different depths can be stored separately through multiple water storage chambers 25. A first filter screen 24 is fixedly connected to the inner wall of the top end of the water storage chamber 25. A water inlet 27 is fixedly connected to the inner wall of the bottom end of the first filter screen 24. A second filter screen 28 is fixedly connected to the inner side of the water inlet 27. The water entering and leaving the water storage chamber 25 is filtered by the first filter screen 24 and the second filter screen 28 to prevent garbage or large impurities from entering. A float 26 is slidably connected to the inner side of the middle section of the water storage chamber 25. The float 26 floats up and can draw external water samples into the water storage chamber 25 through the water inlet 27.

[0041] The control component includes a motor 3 fixed inside the bottom of the sampling bucket 2, which supports and fixes the motor 3. A rotating disk 31 is rotatably connected to the bottom inner side of the sampling bucket 2, which limits the rotation of the rotating disk 31. The output end of the motor 3 is fixedly connected to the rotating disk 31, which supports and fixes the rotating disk 31. The motor 3 drives the rotating disk 31 to rotate. A second through hole 32 is opened on one side of the top of the rotating disk 31. The rotating disk 31 drives the second through hole 32 to rotate, so that different water storage tanks 25 can be connected to external water samples for sampling. When sampling is not required, the rotating disk 31 drives the second through hole 32 to move to a position between two water storage tanks 25, and seals the bottom of multiple water storage tanks 25.

[0042] The connecting assembly includes a fixing ring 21 symmetrically fixed to the outer wall of the collection bucket 2. The collection bucket 2 supports and fixes the fixing ring 21. A shackle 22 is fixedly connected to the outside of the fixing ring 21. The fixing ring 21 supports and fixes the shackle 22. The shackle 22 is slidably connected to the winch 13 near the counterweight 14. The shackle 22 connects the fixing ring 21 and the winch 13, so that the collection bucket 2 can be raised and lowered along the preset direction of the winch 13.

[0043] A rubber layer is provided on the outside of the counterweight 14 to seal the counterweight 14, preventing the counterweight 14 from directly contacting the sampled water and causing corrosion, thus extending its service life.

[0044] Specifically, this emergency multi-depth water quality sampling equipment operates as follows:

[0045] First, the rope 13 on the side away from the counterweight 14 is connected to the hook 23 on the top of the collection bucket 2. Then, the collection bucket 2 and the rope 13 on the other side are connected by the shackle 22 on the outside of the collection bucket 2, so that the collection bucket 2 can slide along the rope 13 on the other side.

[0046] Then, the winch 13 is first released through the winch 12 on the side close to the counterweight 14, so that the counterweight 14 is lowered into the bottom of the water through the first through hole 15. Then, the winch 12 is released through the winch 12 on the side away from the counterweight 14, so that the collection bucket 2 can slide to the bottom along the winch 13 on the side away from the counterweight 14 using the shackle 22.

[0047] After reaching the predetermined water level, the winch 12 stops outputting and stops the collection bucket 2 in the predetermined water level. Then, the motor 3 drives the rotating disk 31 and the second through hole 32 to rotate, so that the second through hole 32 is connected to one of the water storage tanks 25. Thus, the external sampled water can pass through the second filter screen 28 and the water inlet 27 into the water storage tank 25. At the same time, the float 26 can float up to extract the external sampled water. Afterwards, the motor 3 drives the rotating disk 31 and the second through hole 32 to continue rotating, so that the second through hole 32 moves between the two water storage tanks 25.

[0048] After sampling is completed at one water layer, the winch 12 continues to release the rope 13, allowing the collection bucket 2 to continue to descend. After reaching the second predetermined water layer, the above steps are repeated until the sampling work is completed. The winch 12 is then used to retrieve the rope 13, and the shackle 22 is disassembled from the counterweight 14 and the rope 13 respectively. The collection bucket 2 is then brought back, and the counterweight 14 is then removed.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
