They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0022] 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.

[0023] The following is combined with Figure 1-6 The utility model is further described.

[0024] In order to solve the problems existing in the background technology, the present application proposes the following technical solution: a sewage testing sampling device, including a base 2, on which an adjustment plate 1 is slidably connected, and also including a lifting tube 12 and a sampling tube 16. A lifting component is provided on the adjustment plate 1, and the lifting component is connected to the lifting tube 12.

[0025] In the specific design, the lifting assembly includes a motor 4 fixedly connected to the adjusting plate 1, a winding roller 3 fixedly connected to the output end of the motor 4, and a pull rope 6 wound around the winding roller 3. The adjusting plate 1 is rotatably connected to a guide wheel 5, and a pull rope 6 is wound around the outside of the winding roller 3. One end of the pull rope 6 passes through the guide wheel 5 and is fixedly connected to the lifting tube 12. The motor 4 drives the winding roller 3 to rotate, and the winding roller 3 releases the pull rope 6, so that the lifting tube 12 can enter the water area. Conversely, the motor 4 drives the winding roller 3 to wind the pull rope 6, so that the lifting tube 12 can move upward.

[0026] In a further design, a plurality of adjusting tubes 25 are provided in the lifting tube 12, and a water inlet pipe 26 is fixedly connected inside the adjusting tube 25. The water inlet pipe 26 is slidably connected to the lifting tube 12. A water inlet 27 is provided on the outside of the water inlet pipe 26. The water inlet 27 is used to allow water to enter the sampling tube, and a collection tube is fixedly connected to the outside of the water inlet pipe 26. The sampling tube 16 is detachably fixedly connected to the collection tube. A sliding adjustment component for adjusting the sliding of the water inlet pipe 26 is provided between the adjusting tube 25 and the lifting tube 12.

[0027] In the specific design, in order to facilitate water inlet, multiple groups of through holes 15 are provided on the outside of the lifting tube 12. In addition, the bottom of the lifting tube 12 is an open structure, which can also allow water to enter. In addition, the sliding adjustment assembly includes a fixing ring 18 fixedly connected to the outside of the adjusting tube 25, a slide plate 19 fixedly connected to the outside of the fixing ring 18, a mounting plate 22 fixedly connected to the outside of the slide plate 19, and a first electromagnet 23 fixedly connected to the outside of the mounting plate 22. The outside of the lifting tube 12 is fixedly connected with a sliding sleeve 21, and the slide plate 19 passes through the sliding sleeve 21. The position of the first electromagnet 23 on the outside of the lifting tube 12 is fixedly connected with the second electromagnet 24. The outside of the adjusting tube 25 is provided with a spring 20, and the two ends of the spring 20 are fixedly connected to the fixing ring 18 and the outside of the lifting tube 12 respectively. The first electromagnet 23 and the second electromagnet 24 are set with the same poles to repel each other.

[0028] The above technical solution is explained as follows: when the first electromagnet 23 and the second electromagnet 24 are energized, the first electromagnet 23 and the second electromagnet 24 with the same poles repel each other, and under the action of the repulsive force, the regulating tube 25 drives the water inlet pipe 26 to slide toward the inside of the lifting tube 12, so that the water can enter the sampling tube 17 through the lifting tube 12 and then enter the sampling cylinder 16.

[0029] In order to ensure the stability of the lifting pipe 12 when entering the water body, a first counterweight 13 and a second counterweight 14 are fixedly connected to the top and bottom of the lifting pipe 12 respectively.

[0030] In order to facilitate the control of the length of the adjusting plate 1, a plurality of positioning grooves 11 are provided on the top of the adjusting plate 1. A fixing frame 7 is fixedly connected to the base 2, and a threaded rod 9 is rotatably connected to the fixing frame 7. A positioning plate 8 is passed through the fixing frame 7. A connecting plate 10 is fixedly connected to the outside of the positioning plate 8. The connecting plate 10 is threadedly connected to the threaded rod 9, and can be slidably adjusted to control the length of the adjusting plate 1. After the adjustment is completed, the threaded rod 9 can be rotated to drive the positioning plate 8 to rise and fall. It is only necessary to insert the positioning plate 8 into the positioning groove 11 to lock the position of the adjusting plate 1.

[0031] In order for those skilled in the art to fully understand the technical solution, the method of using this embodiment is as follows:

[0032] The base 2 is fixedly connected to the hull and brought to the sampling area. The motor 4 is started to drive the winding roller 3 to rotate, and the winding roller 3 releases the pull rope 6, so that the lifting tube 12 can enter the water area. When it reaches the sampling area, it is only necessary to energize the first electromagnet 23 and the second electromagnet 24. The first electromagnet 23 and the second electromagnet 24 repel each other with the same poles. Under the action of the repulsive force, the regulating tube 25 drives the water inlet pipe 26 to slide toward the inside of the lifting tube 12, so that the water can pass through the lifting tube 12 into the sampling tube 17 and then into the sampling cylinder 16 for storage. After the sampling is completed, the power supply to the first electromagnet 23 and the second electromagnet 24 is stopped. The water inlet pipe 26 will be retracted under the elastic force of the spring 20, so that the water inlet 27 is no longer located in the lifting tube 12, and sampling of multiple layers at different depths can be completed at one time.

[0033] The standard parts used in the present invention can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology.
