[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] Please see Figures 1-4 The present invention provides the following technical solution: a water quality sampling device for ecological environment testing, including a box 1 and a sampling mechanism 5 disposed in the box 1. The box 1 has a guide sliding hole 11. The sampling mechanism 5 includes: a mounting base 51, a peristaltic pump 52, a first elbow 53, a second rigid pipe 56, a support plate 6, a measuring cup 7, and a driving mechanism 8.

[0044] Furthermore, by Figures 1-3As shown, in this embodiment, the mounting base 51 is movably placed inside the housing 1. The peristaltic pump 52 is fixed to the top surface of the mounting base 51. A first elbow 53 passes through the guide sliding hole 11, and one end of the first elbow 53 is connected to the water inlet of the peristaltic pump 52 via a first rigid pipe 54, while the other end is connected to a flexible hose 55. A second rigid pipe 56 is supported and fixed to the top surface of the mounting base 51 by a support frame 57, and the second rigid pipe 56 is connected to a third rigid pipe 59 via a second elbow 58. The third rigid pipe 59 is connected to... Connecting to the outlet end of the peristaltic pump 52, the support plate 6 is fixed inside the housing 1, and multiple support grooves 61 evenly distributed along its length are machined on the top surface of the support plate 6. The measuring cup 7 is placed in the support groove 61 and located directly below the second rigid tube 56. The drive mechanism 8 is drivably connected to the mounting base 51 to drive the mounting base 51 to move. With the above scheme, when using the equipment, the staff will move the water quality sampling equipment to the sampling point, then place the water quality sampling equipment on the ground, and place the hose 55... At the sampling location, the peristaltic pump 52 is then activated. The peristaltic pump 52 draws the sample from the sampling location. The sample water sequentially passes through the flexible tube 55, elbow 53, rigid tube 54, peristaltic pump 52, rigid tube 59, elbow 58, and rigid tube 56, and finally enters the measuring cup 7 for collection. When collecting samples from other locations, the drive mechanism 8 is used to move the mounting base 51 to adjust the position of the rigid tube 56 so that it corresponds to the measuring cup 7 at different locations. Afterwards, the water quality sampling equipment is moved to other sampling points, and then the peristaltic pump 52 is started to draw samples from the sampling location and deliver the samples to the measuring cup 7. This utility model uses the peristaltic pump 52 to draw water quality samples and deliver them to the measuring cup 7. Different measuring cups 7 collect water quality samples from different locations. By adjusting the position of the second rigid tube 56 through the drive mechanism 8, water quality samples can be delivered to different measuring cups 7, which facilitates rapid sampling at different sampling points and greatly improves work efficiency.

[0045] It should be noted that this utility model is powered by a lithium battery. The lithium battery is fixed inside the housing 1 to power the peristaltic pump 52. The switch controlling the peristaltic pump 52 is located on the housing 1. Its wiring principle is a well-disclosed existing technology and will not be described in detail here.

[0046] It is also understandable that when samples are taken from different locations of the same water source, only a very small amount of water remains in the pipe, which will not interfere with the test results. In principle, when samples are taken from different water sources, they will not interfere with the test results either. However, to ensure accuracy, peristaltic pump 52 can be used to pump clean water to flush the pipe and remove the sample remaining in the pipe.

[0047] Preferably, by Figures 1-3As shown in this embodiment, the outer wall of the measuring cup 7 abuts against the inner wall of the support groove 61. With the above solution, the stability of the measuring cup 7 can be effectively improved during use, avoiding shaking during transportation and improving safety.

[0048] Optionally, by Figures 1-3 As shown, in this embodiment, the driving mechanism 8 includes a movable stage 81 and a threaded screw 82. The movable stage 81 is fixed to the bottom surface of the mounting base 51, and the threaded screw 82 is rotatably installed inside the housing 1. The threaded screw 82 passes through the movable stage 81 and is connected to the movable stage 81 by thread engagement. With the above solution, when in use, rotating the threaded screw 82 will cause the movable stage 81 to move due to the thread engagement.

[0049] Preferably, by Figures 1-3 As shown in this embodiment, the drive mechanism 8 further includes a handwheel 83, which is fixed to one end of the threaded screw 82. With the above solution, the threaded screw 82 can be easily rotated by the handwheel 83 during use.

[0050] Preferably, by Figures 1-3 As shown in this embodiment, the drive mechanism 8 further includes a guide rod 84. The two guide rods 84 are symmetrically fixed inside the housing 1 and pass through the moving platform 81. With the above solution, the two guide rods 84 are used to guide the moving platform 81 during use, which improves the stability of the moving platform 81 and the mounting base 51.

[0051] Preferably, by Figure 1 As shown, this embodiment also includes a top cover 2 and a locking mechanism 4. The top cover 2 is hinged to the top of the housing 1. After the top cover 2 is closed, it is locked by the locking mechanism 4. With the above solution, when in use, the top cover 2 is closed when idle, and the locking mechanism 4 is used to lock the top cover 2 to ensure the stability of the top cover 2 after it is closed.

[0052] Optionally, by Figure 1 and Figure 4 As shown, in this embodiment, the locking mechanism 4 includes a connecting block 41, a flip screw 42, and a wing nut 43. The connecting block 41 is fixed to the free end of the top cover 2 and has a notch 411. The flip screw 42 is hinged to the outer wall of the housing 1 and passes through the notch 411. The wing nut 43 is installed on the protruding end of the flip screw 42 by threaded engagement. With the above scheme, when the top cover 2 is closed, the flip screw 42 is flipped up so that it passes through the notch 411. Then, the wing nut 43 is tightened on the protruding end of the flip screw 42 to lock it.

[0053] Preferably, by Figure 1As shown in this embodiment, it also includes a handle 3, which is fixed to the top surface of the top cover 2. With the above solution, the water quality sampling equipment can be easily moved by the handle 3 during use, making it convenient to use in different scenarios.

[0054] It should be noted that the peristaltic pump 52 is a commercially available standard device with a built-in power switch. Those skilled in the art can make conventional selections according to their needs. Its working principle is common knowledge known to those skilled in the art and has been fully disclosed in the prior art, so it will not be elaborated further in this article.

[0055] The circuit connection involved in this utility model is a common method used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments. It belongs to the widely used prior art.

[0056] Components not described in detail in this article are existing technologies.

[0057] The working principle and usage process of this utility model: When using the water quality sampling equipment of this utility model, the staff will move the water quality sampling equipment to the sampling point, then place the water quality sampling equipment on the ground and place the hose 55 at the sampling position.

[0058] Then, the peristaltic pump 52 is started. The peristaltic pump 52 draws the sample from the sampling position. The sample water passes through the hose 55, the first elbow 53, the first rigid tube 54, the peristaltic pump 52, the third rigid tube 59, the second elbow 58 and the second rigid tube 56 in sequence, and finally enters the measuring cup 7 for collection.

[0059] When collecting samples from other locations, first use handwheel 83 to rotate threaded screw 82 to move drive mounting base 51 and adjust the position of rigid tube 56 so that rigid tube 56 corresponds to measuring cup 7 at different positions. Then move the water quality sampling equipment to other sampling points, start peristaltic pump 52 to draw samples from the sampling location and transport the samples into measuring cup 7.

[0060] This invention uses a peristaltic pump 52 to draw water samples and deliver them to measuring cups 7. Different measuring cups 7 collect water samples from different locations. By adjusting the position of the second rigid tube 56 through the drive mechanism 8, water samples can be delivered to different measuring cups 7, facilitating rapid sampling at different sampling points and significantly improving work efficiency.

[0061] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
