[0022] according to Figure 1-Figure 4 A continuous sampling device for soil and water conservation is shown, comprising a sampling tube 1. A plurality of sampling tubes 1 are arranged in a circular array for continuous sampling. The lower end of the sampling tube 1 is connected to a sampling drain pipe 9. A valve is provided on the sampling drain pipe 9 to facilitate the removal of sampled water in the sampling drain pipe 9. A negative pressure suction mechanism 2 is provided on the sampling tube 1. The negative pressure suction mechanism 2 comprises a pull rod 6 and a negative pressure plate 7. One end of the pull rod 6 is arranged in the sampling tube 1, and the other end extends to the outside thereof. The negative pressure plate 7 is fixedly connected to the pull rod 6, and its outer wall is in contact with the inner wall of the sampling tube 1. Pulling the pull rod 6 upward drives the negative pressure plate 7 to move upward, and negative pressure is created in the sampling tube 1 to facilitate sampling and pumping water.

[0023] A cylindrical plate body 3 is fixedly sleeved on the outer end of the sampling tube 1, and the cylindrical plate body 3 is connected to the sampling tube 1. A transition pipe 4 is rotatably connected to the center position of the cylindrical plate body 3. A fixing column 15 is fixedly connected to the upper end of the transition pipe 4, and a handle 8 is fixedly connected to the upper end of the fixing column 15. The transition pipe 4 is connected to the cylindrical plate body 3 through a limiting mechanism 5, and the limiting mechanism 5 is convenient for connecting the transition pipe 4 and the cylindrical plate body 3 together. The limiting mechanism 5 includes a U-shaped seat 12, a hinge seat 13, and a limiting plate 14. The U-shaped seat 12 is fixedly connected to the cylindrical plate body 3, and the hinge seat 13 is fixedly connected to the transition pipe 4. One end of the limiting plate 14 is rotatably connected to the hinge seat 13, and the other end is arranged in the U-shaped seat 12. A water inlet pipe 10 arranged in the cylindrical plate body 3 is connected on the side wall of the sampling tube 1, and the other end of the water inlet pipe 10 extends to the outer wall of the transition pipe 4. A water diversion pipe 11 is connected in the transition pipe 4, and the water diversion pipe 11 is connected to the water inlet pipe 10.

[0024] Principle of the present invention:

[0025] When in use, pull the pull rod 6 upward to drive the negative pressure plate 7 to move upward, and the negative pressure in the sampling tube 1 is generated. The water to be sampled enters the sampling tube 1 through the water guide pipe 11 and the water inlet pipe 10 to sample the water.

[0026] Rotate the limit plate 14 out of the U-shaped seat 12, rotate the cylindrical plate body 3, so that the limit plate 14 is aligned with another U-shaped seat 12, rotate the limit plate 14, so that it enters the corresponding U-shaped seat 12, and position the cylindrical plate body 3 and the transition pipe 4. At this time, the water diversion pipe 11 is aligned with the water inlet pipe 10, and the negative pressure plate is driven to move upward by pulling the pull rod 6 upward. The negative pressure in the sampling tube 1 is generated, and the water to be sampled enters the sampling tube 1 through the water diversion pipe 11 and the water inlet pipe 10 for sampling of the water. In the above manner, continuous sampling can be achieved.

[0027] The present invention describes its implementation mode, which is not restrictive. The drawings show only one of the implementation modes of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it and design structural modes and embodiments similar to the technical solution without creativity without departing from the purpose of the invention, they should all fall within the protection scope of the present invention.
