[0017] 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.

[0018] Please see Figures 1-4 This utility model provides a technical solution: an anti-clogging structure for a water quality sampling pipeline, including a sampling pipe 1, a sampling head 2, an inlet pipe 3, a connecting pipe 4, and an anti-clogging mechanism 5 installed inside the inlet pipe 3. The sampling pipe 1 is connected to the top of the sampling head 2, the inlet pipe 3 is installed on the front side of the sampling head 2, and the connecting pipe 4 is installed between the sampling pipe 1 and the inlet pipe 3. The inlet pipe 3 is connected to the sampling pipe 1 through the connecting pipe 4.

[0019] The anti-blocking mechanism 5 includes multiple water inlet holes 501 that are equidistantly opened at the front end of the water inlet pipe 3. A small electric push rod 502 is installed on the inner wall of the sampling head 2. The output end of the small electric push rod 502 passes through the outer wall of one side of the sampling head 2 and is fixedly connected to the inner wall of the water inlet pipe 3 with a pad 503. Multiple pointed conical shafts 504 are equidistantly opened on one side of the pad 503. A first through hole 505 is opened on one side of the top of the water inlet pipe 3. A protective net 506 is installed on the inner wall of the first through hole 505. A second through hole 507 is opened on one side of the bottom of the water inlet pipe 3. A threaded ring 508 is fixedly installed at the outer edge of the second through hole 507 at the bottom of the water inlet pipe 3. A debris container 509 is threadedly connected to the outer wall of the threaded ring 508.

[0020] In use, sampling pipe 1 is connected to sampling equipment installed on the shore. When the sampling equipment is started, the inlet pipe 3 on the sampling head 2 is connected to the sampling pipe 1 through the connecting pipe 4. Water flows through the inlet pipe 3 into the connecting pipe 4, and then through the connecting pipe 4 into the sampling pipe 1, eventually entering the sampled water for storage. Before sampling, if the inlet hole 501 of the inlet pipe 3 is blocked by debris in the water, the small electric push rod 502 is activated to push the pad 503 forward, and the pointed conical shaft 504 on one side passes through each corresponding inlet hole 501 to squeeze out the debris stuck on its inner wall, clearing the inlet hole 501 and preventing the inlet pipe 3 from being blocked and unable to collect water samples. The water flows through the inlet pipe 3 into the sampling pipe 1. When the water inlet 501 enters the inlet pipe 3, it enters the connecting pipe 4 through the first through hole 505 on the upper side of the inner wall of the inlet pipe 3. When it passes through the first through hole 505, the water flow is intercepted by the protective net 506, which intercepts the large-sized debris and prevents it from accumulating in the sampling pipe 1 and causing internal blockage. The intercepted large-sized debris settles and falls through the second through hole 507 into the debris tank 509. When the sampling head 2 is withdrawn from the water area later, the debris tank 509 can be unscrewed from the threaded ring 508 to collect the large-sized debris for water quality researchers to study. At the same time, it can also facilitate the cleaning of the inside of the inlet pipe 3, reduce the risk of blockage in the sampling pipeline, and improve the efficiency of water quality research.

[0021] Furthermore, the inner wall of the first through hole 505 is connected to the inner wall of one end of the connecting pipe 4, and the outer wall of each conical shaft 504 is connected to the inner wall of each water inlet 501. The first through hole 505 is connected to the connecting pipe 4, thereby connecting the water inlet pipe 3 to the sampling pipe 1. The protective mesh 506 in the first through hole 505 has large holes, which can only intercept debris that may cause blockage inside the sampling pipe 1, and will not intercept trace elements in the water sample.

[0022] Furthermore, the inner wall of the sampling head 2 is provided with an installation groove, and the small electric push rod 502 is installed on one side of the inner wall of the installation groove. The outer wall of the sampling head 2 is provided with a waterproof gasket 6 inside the water inlet pipe 3, and the inner wall of the waterproof gasket 6 is in contact with the outer wall of the output end of the small electric push rod 502.

[0023] A waterproof sleeve 7 is fixedly connected to one side of the top of the sampling head 2. One end of the small electric push rod 502 is connected to a connecting wire 8, and the outer wall of the connecting wire 8 passes through the outer wall of the sampling head 2 and is inserted into the inner wall of the waterproof sleeve 7. When using the small electric push rod 502 in this design, the output end of the small electric push rod 502 is connected to the sampling head 2 through the waterproof gasket 6, so that the connection area is sealed and not easy to get water in. At the same time, the connecting wire 8 of the small electric push rod 502 and the external power supply is inserted into the waterproof sleeve 7 to make the connecting wire 8 waterproof and prevent the line from short-circuiting when it gets wet.

Each embodiment focuses on its differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions of the method embodiments.

[0025] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
