Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, specifically to an environmental monitoring sampling device. Background Technology

[0002] In the field of environmental monitoring, water sampling is a crucial step in obtaining accurate environmental information. Current environmental monitoring sampling devices have some limitations. For example, in complex aquatic environments, the inlet pipe of the sampling device is easily clogged by impurities and suspended solids in the water. Once the inlet pipe is clogged, it not only reduces sampling efficiency, preventing the timely acquisition of representative water samples, but may also affect the accuracy of subsequent monitoring data analysis. Moreover, traditional devices often require manual cleaning or replacement of parts when facing clogging problems, which is extremely inconvenient in difficult environments such as the field, increasing monitoring costs and time. Therefore, the development of an environmental monitoring sampling device that can automatically clear blockages and improve sampling efficiency is urgently needed. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model provides an environmental monitoring sampling device.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] An environmental monitoring sampling device includes a sampling tube, the sampling end of which is fixedly connected to a receiving box. Two obliquely distributed liquid inlet pipes are connected to the side of the receiving box away from the sampling tube. The two liquid inlet pipes are symmetrically arranged along the central axis of the receiving box. A filter plate with filter holes is fixed to the end of the liquid inlet pipe away from the receiving box.

[0006] A guide plate is fixed on the inner wall of the liquid inlet pipe. A sliding rod that can clear the filter holes passes through the guide plate. A return spring is provided on the guide plate to push the sliding rod away from the filter holes.

[0007] The container is rotatably connected to a rotating plate, and the two sides of the rotating plate are respectively in contact with the sliding rods at the ends of the two liquid inlet pipes away from the filter holes.

[0008] When the filter hole on one side of the inlet pipe is blocked, the impact force on the rotating plate on the side corresponding to the blockage is reduced. The rotating plate rotates under force and squeezes the sliding rod on the blocked side to clear the filter hole.

[0009] Preferably, a support plate is fixedly mounted on the sliding rod, one end of the return spring is fixed to the support plate, and the other end of the return spring is fixed to the guide plate.

[0010] Preferably, there are multiple sliding rods, and the ends of the multiple sliding rods away from the filter holes are jointly fixed to an annular plate, and a contact rod is fixed to the side of the annular plate away from the sliding rods.

[0011] Preferably, the end of the sampling tube furthest from the container is fixedly connected to a liquid storage tank, and a liquid suction pump is installed on the sampling tube.

[0012] Preferably, a fixed shaft is fixed on both sides of the middle part of the rotating plate, and a shaft hole adapted to the fixed shaft on the rotating plate is opened on one of the opposite inner walls of the receiving box.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] When the filter hole on one side of the liquid inlet pipe is blocked, the impact force on the rotating plate on the side corresponding to the blockage is reduced. The rotating plate rotates under force and squeezes the sliding rod on the blocked side to clear the filter hole, thereby realizing the self-clearing of the environmental monitoring sampling device and greatly improving the sampling efficiency.

[0020] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0021] Example

[0022] like Figure 1-3 As shown, an environmental monitoring sampling device includes a sampling tube 1. The sampling end of the sampling tube 1 is fixedly connected to a receiving box 2. Two obliquely distributed liquid inlet pipes 3 are connected to the side of the receiving box 2 away from the sampling tube 1. The two liquid inlet pipes 3 are symmetrically arranged along the central axis of the receiving box 2. A filter plate 4 with filter holes is fixed to the end of the liquid inlet pipe 3 away from the receiving box 2.

[0023] A guide plate 5 is fixed on the inner wall of the liquid inlet pipe 3. A sliding rod 6 that can clear the filter holes is passed through the guide plate 5. A return spring 8 is provided on the guide plate 5 to press the sliding rod 6 away from the filter holes.

[0024] The container 2 is rotatably connected to a rotating plate 11. The two sides of the rotating plate 11 are in contact with the sliding rods 6 at the ends of the two liquid inlet pipes 3 that are away from the filter holes.

[0025] When the filter hole on the inlet pipe 3 on one side is blocked, the impact force on the rotating plate 11 on the side corresponding to the blockage is reduced, and the rotating plate 11 rotates under force to squeeze the sliding rod 6 on the blocked side to clear the filter hole.

[0026] When water resources in lakes and rivers need to be sampled, the water flow impacts both sides of the rotating plate 11. When the filter hole on the side corresponding to the rotating plate 11 is blocked, the impact of the water flow on the blocked side of the rotating plate 11 will be smaller. At this time, the rotating plate 11 will rotate due to the imbalance of forces. The rotation of the rotating plate 11 will squeeze the sliding rod 6 on the blocked side, causing the sliding rod 6 to clear the filter hole, thereby realizing the self-clearing of the environmental monitoring sampling device and greatly improving the sampling efficiency.

[0027] A support plate 7 is fixedly mounted on the sliding rod 6. One end of the return spring 8 is fixed on the support plate 7, and the other end of the return spring 8 is fixed on the guide plate 5.

[0028] There are multiple sliding rods 6, and an annular plate 9 is fixed to the end of the multiple sliding rods 6 away from the filter hole. A contact rod 10 is fixed to the side of the annular plate 9 away from the sliding rod 6.

[0029] A liquid storage tank 12 is fixedly connected to the end of the sampling tube 1 away from the container 2, and a liquid suction pump 13 is installed on the sampling tube 1;

[0030] A fixed shaft is fixed on both sides of the middle part of the rotating plate 11, and a shaft hole that matches the fixed shaft on the rotating plate 11 is opened on one of the opposite inner walls of the receiving box 2.

[0031] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
