Description

Technical Field

[0001] This utility model relates to the field of water sample collection technology, and in particular to a sampling device for water environment engineering testing. Background Technology

[0002] Water sample data is required during water environment engineering testing. Water sample data can accurately assess water quality, support pollution prevention and control decisions, verify the treatment effect of engineering, ensure water safety and compliance, and provide a scientific basis for water environment protection and sustainable use.

[0003] Currently, water sampling primarily involves personnel traveling by sampling boat to different locations within the sampling area and then releasing sampling containers to collect samples. However, in practice, this requires personnel to approach the bow of the boat, release the sampling container into the water to extract the sample, and then retrieve the container after extraction. This process involves personnel operating near the edge of the boat, which carries certain risks. Furthermore, weeds, debris, and other contaminants can easily enter the sampling container, hindering sample collection and reducing sample quality.

[0004] Therefore, a sampling device for water environment engineering testing is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a sampling device for water environment engineering testing, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sampling device for water environment engineering testing, comprising a base, a support platform slidably disposed on the base, a vertical plate mounted on the support platform, a take-up and untake-down roller rotatably disposed within the vertical plate, a take-up and untake-down roller mounted on the take-up and untake-down roller, a sling wound within the take-up and untake-down roller, a connecting block mounted at the bottom of the sling, a hook mounted on the connecting block, a hanging bracket attached to the hook, a sampling bucket disposed below the hanging bracket, a support plate mounted on the base, a screw rotatably disposed within the support plate, the support platform screwed onto the screw, a first drive motor mounted on the support plate, and the screw mounted at the output end of the first drive motor.

[0007] Preferably, the sampling bucket is provided with a cover plate on top, and the hanging bracket is installed on the cover plate.

[0008] Preferably, an isolation net is installed inside the cover plate, and a locking buckle is installed between the sampling bucket and the cover plate.

[0009] Preferably, the sampling bucket is equipped with a discharge pipe, and a valve body is installed inside the discharge pipe.

[0010] Preferably, a guide rail is mounted on the base, and a sliding sleeve is slidably mounted on the guide rail, with the sliding sleeve installed at the bottom of the support platform.

[0011] Preferably, a second drive motor is installed on the vertical plate, and the take-up and untake-down reel is installed at the output end of the second drive motor.

[0012] Preferably, a mounting block is installed on the base.

[0013] The beneficial effects of this utility model are:

[0014] In this invention, the rotation of the screw drives the support platform and sampling bucket forward, positioning the sampling bucket above the water surface. The unwinding of the sling releases the sampling bucket, allowing it to descend into the water for sampling. After sampling, the first drive motor is activated in reverse to move the support platform backward, lifting the sampling bucket above the water surface and onto the hull. This eliminates the need for personnel to stand at the edge of the hull to collect samples, reducing the risk of injury during sampling.

[0015] In this invention, water samples from the collection area are passed through an isolation net into the sampling bucket. The isolation net can coarsely filter the sampled water to prevent garbage, aquatic plants, and other substances from entering the sample and interfering with the sampling. At the same time, it does not filter out microscopic solid substances in the sample, thus avoiding affecting the accuracy of the water sample detection. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example:

[0023] like Figure 1-4 As shown, this embodiment provides a sampling device for water environment engineering testing, including a base 1, a support platform 2 slidably mounted on the base 1, a vertical plate 3 mounted on the support platform 2, a winding and unwinding reel 4 rotatably mounted inside the vertical plate 3, a winding and unwinding wheel 5 mounted on the winding and unwinding reel 5, a sling 6 wound inside the winding and unwinding wheel 5, a connecting block 7 mounted at the bottom of the sling 6, a hook 8 mounted on the connecting block 7, a hanging frame 9 hooked to the hook 8, a sampling bucket 10 positioned below the hanging frame 9, a support plate 11 mounted on the base 1, a screw 12 rotatably mounted inside the support plate 11, the support platform 2 screwed onto the screw 12, a first drive motor 13 mounted on the support plate 11, and the screw 12 mounted at the output end of the first drive motor 13; the base 1 is pre-fixed to the hull by the mounting block 22, so that the end of the base 1 protrudes from the edge of the hull. Before sampling, the hull is steered to a suitable position, and then the hook 8 is hung in the hanging frame 9 to suspend the sampling bucket 10. Then start the first drive motor 13. The rotation of the first drive motor 13 will drive the screw 12 to rotate. The rotation of the screw 12 will drive the support platform 2 to move forward. The forward movement of the support platform 2 will drive the sampling bucket 10 to move forward, so that the sampling bucket 10 is above the sampling water surface.

[0024] During sampling, the second drive motor 21 is activated. The rotation of the second drive motor 21 drives the take-up and undo reel 4, which in turn drives the take-up and undo reel 5. This reel 5 then unwinds the sling 6, releasing the sampling bucket 10, which descends into the water to collect the sample. After sampling, the first drive motor 13 is activated in reverse to move the support platform 2 backward, lifting the sampling bucket 10 above the water surface and onto the hull. The hanger 9 is then removed from the hook 8, allowing the sampling bucket 10 to be retrieved and the sample collected. This eliminates the need for personnel to stand at the edge of the hull to collect samples, reducing the risk of injury during sampling.

[0025] To prevent debris, aquatic plants, and other substances from entering the collected sample, the sampling container 10 is equipped with a cover plate 14 on top. A hanger 9 is mounted on the cover plate 14, and an isolation net 15 is installed inside the cover plate 14. Locks 16 are installed on the sampling container 10 and the cover plate 14. Water samples from the collection area enter the sampling container 10 through the isolation net 15. The isolation net 15 coarsely filters the sampled water, preventing debris, aquatic plants, and other substances from entering the sample and interfering with sampling. It also does not filter out microscopic solid particles in the sample, thus avoiding affecting the accuracy of the water sample testing. After use, the cover plate 14 and isolation net 15 can be disassembled by unlocking the lock 16 to clean the inside of the sampling container 10.

[0026] To facilitate the collection of samples from the sampling container 10, a discharge pipe 17 is installed on the sampling container 10, and a valve body 18 is installed inside the discharge pipe 17; when the valve body 18 is opened, the samples from the sampling container 10 can be collected through the discharge pipe 17.

[0027] To guide the movement of the sampling bucket 10, a guide rail 19 is installed on the base 1, and a sliding sleeve 20 is slidably installed on the guide rail 19. The sliding sleeve 20 is installed at the bottom of the support platform 2. Since the guide rail 19 is slidably installed on the sliding sleeve 20, it can guide the movement of the sampling bucket 10, so that the sampling bucket 10 can only move along the water surface above the base 1.

[0028] To secure the base 1 and drive the release and rewind of the sampling bucket 10, a second drive motor 21 is mounted on the vertical plate 3, and a take-up and untake-down reel 4 is mounted on the output end of the second drive motor 21. A mounting block 22 is mounted on the base 1. The base 1 can be fixed to the hull by the mounting block 22. The rotation of the second drive motor 21 will drive the take-up and untake-down reel 4 to rotate, which in turn will drive the take-up and untake-down reel 5 to rotate, thereby driving the take-up and untake-down reel 5 to release and rewind the sling 6, which in turn drives the release and rewind of the sampling bucket 10.

[0029] Working principle: In use, the base 1 is pre-fixed to the hull using the mounting block 22, so that the end of the base 1 protrudes from the edge of the hull. Before sampling, the hull is steered to a suitable position, and the hook 8 is hung in the bracket 9 to suspend the sampling bucket 10. Then, the first drive motor 13 is started. The rotation of the first drive motor 13 will drive the screw 12 to rotate, which will move the support platform 2 forward. The forward movement of the support platform 2 will move the sampling bucket 10 forward, so that the sampling bucket 10 is positioned above the water surface for sampling. During sampling, the second drive motor 21 is activated. The rotation of the second drive motor 21 drives the take-up and unwind reel 4, which in turn drives the take-up and unwind reel 5. This reel 5 then unwinds the sling 6, releasing the sampling bucket 10, which descends into the water. The water sample from the sampling area passes through the isolation net 15 into the sampling bucket 10. The isolation net 15 coarsely filters the sampled water, preventing debris and weeds from entering the sample and interfering with the sampling. It also does not filter out microscopic solid particles in the sample, thus avoiding affecting the accuracy of the water sample testing. After sampling, the first drive motor 13 is activated in reverse to drive the support platform 2, moving it backward and lifting the sampling bucket 10 from the water surface to above the hull. The hanger 9 is then removed from the hook 8, allowing the sampling bucket 10 to be taken out. The valve 18 is then opened, and the sample inside the sampling bucket 10 can be collected through the discharge pipe 17. The operation is convenient and easy to use, reducing the risk of sample collection.

[0030] 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.
