Description

Technical Field

[0001] This utility model relates to the field of freshwater sampling technology, and in particular to an environmental engineering sampling device. Background Technology

[0002] The factory conducts environmental monitoring during operation and commissioning. Environmental monitoring refers to the activities of environmental monitoring agencies in monitoring and measuring the status of environmental quality. Environmental monitoring involves monitoring and measuring indicators that reflect environmental quality.

[0003] Currently, in existing technologies, water sampling is an important step in water quality testing. Freshwater samples are currently collected by throwing glass bottles into rivers. This method does not allow for free selection of sampling locations, nor can it sample water at different depths. Consequently, the freshwater samples obtained are not representative, which affects subsequent water quality testing and leads to inaccurate test results. To address this, we provide an environmental engineering sampling device. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides an environmental engineering sampling device. Water sampling is a crucial step in water quality testing. Currently, freshwater samples are typically taken by throwing glass bottles into rivers. This method does not allow for flexible selection of sampling locations or sampling at different depths, resulting in unrepresentative freshwater samples. This affects subsequent water quality testing and leads to inaccurate test results.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An environmental engineering sampling device includes a stainless steel tube, a sampling box fixedly connected to the bottom end of the stainless steel tube, a water inlet fixedly connected to the bottom of the sampling box, a pull rope inside the stainless steel tube, a pulling block fixedly connected to the top of the pull rope, a linkage component at the bottom of the pull rope, a sealing component below the linkage component, and a water inlet channel in the middle of the bottom of the sampling box.

[0009] Preferably, the linkage includes a strong magnetic plate, which is fixedly connected to the bottom end of the pull rope. A restoring spring is fixedly connected to the top center of the strong magnetic plate, and a connecting plate is fixedly connected to the top of the restoring spring. The connecting plate is welded to the inner wall of the sampling box. The sealing component includes a rod, which is inserted into the bottom of the sampling box near the water inlet channel. A magnetic rod with opposite magnetism to the strong magnetic plate is fixedly connected to the top of the rod. A side plate is fixedly connected to one side of the bottom of the rod. A return spring is fixedly connected between the side plate and the inner wall of the sampling box. A sealing gasket is fixedly connected to the bottom of the magnetic rod above the water inlet channel. The rod and the side plate are welded as a single unit.

[0010] The technical effect of adopting the above-mentioned further solution is as follows: The length of the stainless steel pipe and the pull rope in this device can be customized according to the specific application. When sampling water in the river, the stainless steel pipe is held and the sampling box can be placed at different depths in the river according to the sampling depth. Then, the pull block at the upper end of the pull rope is pulled. At this time, the strong magnetic plate moves upward with the pull rope and compresses the return spring. Since the magnetism of the magnetic rod is opposite to that of the strong magnetic plate, the magnetic rod will move upward with the strong magnetic plate. At the same time as the magnetic rod moves upward, it drives the insertion rod to move upward and causes the side plate to compress the return spring. At this time, the sealing gasket is no longer in contact with the upper end of the water inlet channel, so the water in the river can enter the sampling box from the water inlet channel. After the sampling is completed, the pull block at the upper end of the pull rope is released. At this time, the return spring and the return spring return and drive the strong magnetic plate and the magnetic rod to move downward until the sealing gasket contacts the inside of the sampling box, which can prevent the water inside the sampling box from flowing out when the sampling box is removed.

[0011] (III) Beneficial Effects

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention, by setting up a linkage component, can achieve the following by pulling the upper end of the pull rope: with the cooperation of the strong magnetic plate, the connecting plate and the restoring spring, the strong magnetic plate moves upward with the pull rope and compresses the restoring spring. Since the magnetic properties of the magnetic rod are opposite to those of the strong magnetic plate, the magnetic rod will also move upward with the strong magnetic plate.

[0014] This invention, through the installation of a sealing element, utilizes the combined action of the insertion rod, side plate, return spring, magnetic rod, and sealing gasket. As the magnetic rod moves upward, it simultaneously drives the insertion rod upward, causing the side plate to compress the return spring. At this point, the sealing gasket is no longer in contact with the upper end of the water inlet channel, allowing water from the river to enter the sampling box through the inlet channel. After sampling, the pulling block at the upper end of the pull rope is released. The return spring and reset spring then return to their original positions, causing the strong magnetic plate and magnetic rod to move downward until the sealing gasket contacts the inside of the sampling box, thus preventing water from flowing out when the sampling box is removed.

[0021] This application provides an environmental engineering sampling device. By incorporating a linkage mechanism, a strong magnetic plate, a connecting plate, and a restoring spring, pulling the upper end of the pull rope causes the strong magnetic plate to move upwards, compressing the restoring spring. Since the magnetic rod's magnetism is opposite to that of the strong magnetic plate, it also moves upwards. A sealing element, along with the insertion rod, side plate, return spring, magnetic rod, and sealing gasket, causes the insertion rod to move upwards, compressing the return spring. At this point, the sealing gasket is no longer in contact with the upper end of the water inlet channel, allowing water from the river to enter the sampling box. After sampling, releasing the upper end of the pull rope causes the restoring spring and return spring to return to their original positions, moving the strong magnetic plate and magnetic rod downwards until the sealing gasket contacts the inside of the sampling box, preventing water from flowing out when the sampling box is removed.

[0022] The technical solution in this application aims to effectively address the problem that water sampling is a crucial step in water quality testing. Currently, freshwater samples are typically taken by throwing glass bottles into rivers. This method does not allow for flexible selection of sampling locations or sampling at different depths, resulting in unrepresentative freshwater samples. This affects subsequent water quality testing and leads to inaccurate results. The overall approach is as follows:

[0023] like Figures 1 to 4To address the problems existing in the prior art, this utility model provides an environmental engineering sampling device, including a stainless steel pipe 1, a sampling box 2 fixedly connected to the bottom end of the stainless steel pipe 1, a water inlet 3 fixedly connected to the bottom of the sampling box 2, a pull rope 4 inside the stainless steel pipe 1, a pulling block 5 fixedly connected to the top of the pull rope 4, a linkage 40 at the bottom of the pull rope 4, a sealing element 41 below the linkage 40, a water inlet channel 201 in the middle of the bottom of the sampling box 2, and a strong magnetic plate 401 fixedly connected to the bottom end of the pull rope 4, and a restoring spring 403 fixedly connected to the middle of the top of the strong magnetic plate 401. A connecting plate 402 is fixedly connected to the top of the restoring spring 403. The connecting plate 402 is welded to the inner wall of the sampling box 2. The sealing element 41 includes a rod 411. The rod 411 is inserted into the bottom of the sampling box 2 near the water inlet channel 201. A magnetic rod 414 with the opposite magnetism to the strong magnetic plate 401 is fixedly connected to the top of the rod 411. A side plate 412 is fixedly connected to one side of the bottom of the rod 411. A return spring 413 is fixedly connected between the side plate 412 and the inner wall of the sampling box 2. A sealing gasket 415 is fixedly connected to the bottom of the magnetic rod 414 above the water inlet channel 201. The rod 411 and the side plate 412 are welded as a whole.

[0024] By adopting the above technical solution, the lengths of the stainless steel pipe 1 and the pull rope 4 in this device can be customized according to specific usage. When sampling water in a river, by holding the stainless steel pipe 1, the sampling box 2 can be placed at different depths in the river according to the sampling depth. Then, the pull block 5 at the upper end of the pull rope 4 is pulled. At this time, the strong magnetic plate 401 moves upward with the pull rope 4 and compresses the return spring 403. Since the magnetism of the magnetic rod 414 is opposite to that of the strong magnetic plate 401, the magnetic rod 414 will move upward with the strong magnetic plate 401. As the device moves upward, it causes the insertion rod 411 to move upward, which in turn causes the side plate 412 to compress the return spring 413. At this time, the sealing gasket 415 is no longer in contact with the upper end of the water inlet channel 201, so the water in the river can enter the sampling box 2 from the water inlet channel 201. After sampling, the pulling block 5 at the upper end of the pull rope 4 is released. At this time, the return spring 403 and the return spring 413 return to their original positions and cause the strong magnetic plate 401 and the magnetic rod 414 to move downward until the sealing gasket 415 contacts the inside of the sampling box 2, which can prevent the water inside the sampling box 2 from flowing out when it is taken out.

[0025] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
