[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figures 1-6 The surface water quality online monitoring sampling device shown includes a sampling cylinder 1. A movable plug 12 is slidably disposed inside the sampling cylinder 1. A circular groove is opened at the top of the sampling cylinder 1, and a movable rod 13 is slidably disposed inside the circular groove. The movable plug 12 is fixedly connected to the movable rod 13, and a crossbar 14 is fixedly connected to the top of the movable rod 13. A connecting pipe 2 is connected to the bottom of the sampling cylinder 1, and a sampling cover 3 is connected to the bottom of the connecting pipe 2. A filter plate 5 is fixedly connected inside the sampling cover 3.

[0025] Specifically, the device is carried to the sampling point, and then the sampling tube 1 is held in hand. The sampling cover 3 is aimed at the surface water, and then the horizontal bar 14 is pulled upward. The horizontal bar 14 drives the movable plug 12 to move upward through the movable rod 13, so that the surface water can be drawn into the sampling tube 1 through the sampling cover 3 for collection and sampling. During the extraction process, the filter plate 5 can filter impurities.

[0026] This device works in conjunction with online surface water quality monitoring agencies to test collected surface water samples. These agencies can use, but are not limited to, the SWA-2000 online water quality monitor to detect pH values, turbidity, and other parameters. The device's flexibility allows for convenient sampling from multiple locations, improving the flexibility and comprehensiveness of the testing.

[0027] In view of the fact that impurities are easily attached to the filter plate 5 due to suction force in the sampling process, causing the filter plate 5 to be blocked, in order to prevent the filter plate 5 from being blocked, a threaded cylinder 6 is rotatably arranged on the filter plate 5, and the threaded cylinder 6 extends to the inside of the connecting pipe 2, the bottom of the threaded cylinder 6 is fixedly connected with a cleaning box 7, a square groove 8 is formed through the side wall of the cleaning box 7, a push strip 9 is fixedly connected to the outer wall of the cleaning box 7, and the push strip 9 is distributed corresponding to the square groove 8 and is slidably attached to the lower surface of the filter plate 5. A first threaded rod 11 is threadedly connected to the inside of the threaded cylinder 6, and the first threaded rod 11 is fixedly connected to a movable plug 12.

[0028] Specifically, when the movable plug 12 is moved upward by the movable rod 13, the first threaded rod 11 is synchronously moved upward, and since the first threaded rod 11 is threadedly connected with the threaded cylinder 6, the threaded cylinder 6 drives the cleaning box 7 to rotate, at this time, the push strip 9 is at the front end of the rotating direction of the cleaning box 7 corresponding to the square groove 8, the push strip 9 pushes and scrapes the impurities attached to the filter plate 5, and the impurities enter the inside of the cleaning box 7 from the square groove 8, achieving the effect of cleaning and collecting the impurities, improving the sampling efficiency, and thus improving the effect of the online monitoring of the surface water quality.

[0029] The cleaning box 7 can also be provided as a detachable structure, facilitating the treatment of the impurities in the cleaning box 7.

[0030] In view of the fact that the surface water also enters the inside of the cleaning box 7 from the square groove 8 in the rotating process of the cleaning box 7, in order to reduce the resistance of the cleaning box 7, a plurality of circular holes 10 are formed in the side wall of the cleaning box 7, the inner diameter of the circular hole 10 is small, and the surface water can pass through but the impurities cannot pass through.

[0031] A limiting groove, a limiting block or the like structure (not shown in the figure) can be arranged between the movable plug 12 and the inner wall of the sampling cylinder 1, so that the movable plug 12 can only move up and down but cannot rotate, ensuring the cooperation of the first threaded rod 11 and the threaded cylinder 6.

[0032] In order to prevent the first threaded rod 11 from being separated from the threaded cylinder 6, a limiting rod 15 is fixedly connected to the upper surface of the movable plug 12, and when the limiting rod 15 abuts against the top end of the sampling cylinder 1, the first threaded rod 11 cannot be separated from the threaded cylinder 6.

[0033] The two sides of the connecting pipe 2 are fixedly connected with square boxes 16, and the square boxes 16 are communicated with the connecting pipe 2. A partition plate 17 is slidably arranged in the inside of the square box 16, an arc opening 4 matched with the threaded cylinder 6 is formed in the end of the partition plate 17 close to the threaded cylinder 6, a second threaded rod 18 is threadedly connected to the end of the square box 16 away from the connecting pipe 2, the partition plate 17 is rotatably connected to the corresponding second threaded rod 18, and the end of the second threaded rod 18 located outside the square box 16 is fixedly connected with a rotating block 19. In specific use, a rubber pad can be arranged on the partition plate 17 to improve the sealing effect.

[0034] Specifically, when sampling at a position having a certain distance from the online monitoring mechanism of surface water quality, before the sampling operation, the second threaded rod 18 is rotated by rotating the rotating block 19, so that the partition plate 17 is retracted to the inside of the square box 16, and the sampling cylinder 1 can be communicated with the sampling cover 3 through the connecting pipe 2; after the sampling is completed, the rotating block 19 is reversed, the partition plate 17 moves to the direction of the connecting pipe 2, the arc opening 4 is attached to the threaded cylinder 6, the connecting pipe 2 is cut off, and then the extracted surface water sample is carried to the online monitoring mechanism of surface water quality.
