[0020] 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.

[0021] Please see Figure 1-5 One embodiment of this utility model is a water quality sampler for water conservancy projects, comprising:

[0022] First connecting rod 1, one end of the first connecting rod 1 is fixedly connected to a sealing cover 2, the other end of the sealing cover 2 is connected to a second connecting rod 3, and the other end of the second connecting rod 3 is connected to a threaded cylinder 4;

[0023] The threaded rod 5 is threadedly connected inside the threaded cylinder 4. One end of the threaded rod 5 is connected to a third connecting rod 8, and the other end of the third connecting rod 8 is connected to a fourth connecting rod 11. The other end of the fourth connecting rod 11 is fixedly connected to a sampling cup 12, and a sealing cap 2 is fitted onto the opening of the sampling cup 12. Through the threaded connection between the threaded cylinder 4 and the threaded rod 5, the sealing cap 2 and the sampling cup 12 can be separated and sealed by the rotation of their threads. This allows the device to achieve precise sampling at a fixed depth when sampling water sources. At the same time, its modular structure allows for flexible splicing of different lengths, thereby improving the flexibility of the device and enabling sampling and processing of water sources at different depths.

[0024] Furthermore, a sealing gasket is provided on the side of the sealing cap 2 near the sampling cup 12. The inner diameter of the sealing cap 2 is equal to the outer diameter of the sampling cup 12. The center of the first connecting rod 1 and the sealing cap 2 are both provided with a first through hole, and the fourth connecting rod 11 slides through the inside of the first through hole.

[0025] Furthermore, a positioning flange is provided at the end of the first connecting rod 1 near the sealing cover 2, and the positioning flange is fixedly connected to the sealing cover 2 by countersunk bolts. A first external thread is provided at the end of the first connecting rod 1 away from the sealing cover 2.

[0026] Furthermore, the second connecting rod 3 is provided with a first internal thread at the end near the first connecting rod 1, and the first internal thread is compatible with the first external thread. The second connecting rod 3 is provided with a second external thread at the end away from the first connecting rod 1. The threaded cylinder 4 is provided with a second internal thread at the end near the second connecting rod 3, and the second internal thread is compatible with the second external thread. The length connection is achieved through their threaded connection.

[0027] Furthermore, the inner diameters of the first connecting rod 1 and the second connecting rod 3 are the same, and the outer diameters of the third connecting rod 8 and the fourth connecting rod 11 are the same. The first connecting rod 1 and the fourth connecting rod 11, as well as the second connecting rod 3 and the third connecting rod 8, have a certain degree of damping, thereby enabling them to slide while preventing them from falling off at will. The outer wall of the threaded cylinder 4 is provided with a first grip, and the end of the threaded rod 5 is provided with a second grip. The grips facilitate the rotational drive of the threaded cylinder 4 and the threaded rod 5.

[0028] Furthermore, a first hook 6 is fixedly connected to one end of the threaded rod 5 near the third connecting rod 8, and a first adjusting hook 7 is slidably inserted into one end of the third connecting rod 8 near the threaded rod 5. The first hook 6 and the first adjusting hook 7 are hooked together. A second hook 9 is fixedly connected to one end of the third connecting rod 8 near the fourth connecting rod 11, and a second adjusting hook 10 is slidably inserted into one end of the fourth connecting rod 11 near the third connecting rod 8. The second adjusting hook 10 and the second hook 9 are hooked together. The second hook 9 and the first hook 6 have the same structure, and the second adjusting hook 10 and the first adjusting hook 7 have the same structure. The cross-section of the second adjusting hook 10 and the first adjusting hook 7 is hexagonal. The second adjusting hook 10 and the first adjusting hook 7 both include a guide shaft and a hook. The hooks are hooked together to facilitate their connection and docking. This allows the threaded rod 5 to rotate while driving the third connecting rod 8 and the fourth connecting rod 11 to rotate synchronously, thereby achieving the separation of the sampling cup 12 and the sealing cap 2.

[0029] Working principle: The sealing cap 2, threaded cylinder 4, threaded rod 5, and sampling cup 12 used in this application are all commercially available products. Their principles and connection methods are existing technologies well known to those skilled in the art, and therefore will not be described in detail here. When using this utility model, the device is first assembled. Then, with the sealing cap 2 and sampling cup 12 sealed, the sampling cup 12 is lowered to the bottom of the water. Then, by rotating the threaded cylinder 4 and threaded rod 5 by hand, the displacement of the threaded cylinder 4 and threaded rod 5 can be achieved through their threaded connection. Then, by separating the sealing cap 2 and sampling cup 12, the water source inside the sampling cup 12 can be sampled. Finally, the device is reversed to seal the sealing cap 2 and sampling cup 12, and then the sampling cup 12 can be lifted upwards.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
