Therefore, they cannot be understood as limitations on the present invention.

[0020] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0021] The following is combined with Figure 1-4 The utility model is further described.

[0022] In order to solve the problems existing in the background technology, the present application proposes the following technical solutions: a water quality sampler, comprising a sampling tube 1, the sampling tube 1 is a cylindrical or rectangular cavity structure, in this embodiment it is a cylindrical structure, the outside of the sampling tube 1 is fixedly connected to a pull rope 3, the outside of the pull rope 3 is provided with a scale for observing the depth of the sampling tube 1 descent, and the outside of the sampling tube 1 is fixedly connected to a fixed tube 2, the inside of the fixed tube 2 is slidably connected to an inner tube 13, the outside of the fixed tube 2 is provided with a second slot 15, the outside of the inner tube 13 is provided with a first slot 14, in the initial state, the first slot 14 and the second slot 15 are staggered, and water can only enter when the first slot 14 and the second slot 15 correspond.

[0023] In this embodiment, a rubber membrane 4 is fixedly connected to the outside of the sampling tube 1. The rubber membrane 4 is a frame-shaped structure. A slide 6 is fixedly connected to the outside of the rubber membrane 4. A pushing component is also provided in the sampling tube 1. The pushing component is used to push the inner tube 13 to slide.

[0024] In the specific design, the pushing assembly includes an inclined block 16 arranged in the sampling tube 1, a connecting rod 17 fixedly connected to the top of the inclined block 16, and a first spring 18 sleeved on the outside of the connecting rod 17. The connecting rod 17 is fixedly connected to the inner tube 13, and a partition 21 is fixedly connected to the fixed tube 2. The two ends of the first spring 18 are respectively connected to the partition 21 and the inclined block 16, and the connecting rod 17 passes through the partition 21.

[0025] Among them, the outside of the slide plate 6 is fixedly connected to a slide rod 11, one end of the slide rod 11 passes through the sampling tube 1, and one end of the slide rod 11 is rotatably connected to a contact wheel 12, which contacts the inclined block 16. In order to guide the slide plate 6, a guide rod 5 is fixedly connected to the outside of the sampling tube 1, and the guide rod 5 passes through the slide plate 6.

[0026] The above technical solution is explained as follows: when the sampling tube 1 enters the lake water area, the water pressure will act on the slide 6, the slide 6 compresses the rubber membrane 4, the slide 6 drives the slide rod 11 to slide, and the slide 6 resists the inclined block 16 through the resistance wheel 12, so that the inclined block 16 pushes the inner tube 13 to slide upward, and the inner tube 13 slides upward, so that the first slot 14 corresponds to the second slot 15, so that the water can pass through the inner tube 13, the first slot 14 and the second slot 15 into the sampling tube 1 for storage.

[0027] In another design, fixed plates 7 are fixedly connected to both sides of the outside of the slide 6, and a bayonet 8 is provided on the fixed plate 7. A fixed plate 9 is fixedly connected to the outside of the sampling tube 1, and a threaded groove 10 is provided on the outside of the fixed plate 9. If sampling is required in deeper waters, in order to control the sliding of the slide 6 and prevent the slide 6 from sliding open prematurely, a threaded column 19 can be threadedly connected in the threaded groove 10, and a second spring 20 is sleeved on the outside of the threaded column 19, so that one end of the second spring 20 is in contact with the outside of the fixed plate 7, thereby blocking the slide 6.

[0028] To enable those skilled in the art to fully understand the technical solution, this embodiment is summarized as follows:

[0029] When sampling is needed, the sampling tube 1 is thrown into the lake area where sampling is needed, and the depth of the sampling tube 1 descending is observed by observing the scale line on the pull rope 3. When the set depth is reached, the water pressure will act on the slide plate 6, and the slide plate 6 compresses the rubber membrane 4, and the slide plate 6 drives the slide rod 11 to slide. The slide plate 6 contacts the inclined block 16 through the contact wheel 12, so that the inclined block 16 pushes the inner tube 13 to slide upward, and the inner tube 13 slides upward, so that the first notch 14 corresponds to the second notch 15, so that water can enter the sampling tube 1 through the inner tube 13, the first notch 14 and the second notch 15 for storage; after the sampling is completed, the sampling tube 1 can be pulled out, and the effect of the water pressure is lost. The inclined block 16 slides out and resets under the elastic force of the first spring 18. At the same time, through the contact with the contact wheel 12, the slide plate 6 is reset to the initial position, the first notch 14 and the second notch 15 are staggered, and the inner tube 13 and the fixed tube 2 are closed and no water enters.
