A dioxin sampling device for water quality detection

Abstract

The utility model discloses a dioxin sampling device for water quality detection, which relates to the technical field of water quality detection and comprises a shell, wherein both sides of the exterior of the shell are fixedly connected with fixed plates. In the utility model, a sampling bottle is placed in a first placement rack, and the sampling bottle is positioned between the first placement rack and the second placement rack by cooperation between a first clamping plate and a second clamping plate. By staggeredly distributing four sampling bottles on both sides of the shell, multiple water body samples can be taken at a time, thereby improving the efficiency of dioxin sampling. Meanwhile, the four sampling bottles are evenly distributed on both sides of the shell, thereby balancing the weight of both sides when lifting after sampling. By rotating the first rotating rod, the second rotating rod can be driven to rotate, and while the second rotating rod rotates, multiple connecting rods are driven to rotate, and two movable plates on the same side of the shell move synchronously, thereby driving a sealing plug to move. When the sealing plug is separated from the sampling bottle, water enters the interior of the sampling bottle for sampling, thereby improving the efficiency of sample sampling.

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. Example

[0023] like Figure 1-4 As shown, the utility model provides a dioxin sampling device for water quality detection, including a shell 1, both sides of the shell 1 are fixedly connected with connecting plates 11, one side of the connecting plate 11 is fixedly connected with a first placement rack 4, one side of the first placement rack 4 is rotatably connected with a second placement rack 5, one side of the second placement rack 5 is fixedly connected with a second fixing plate 17, one side of the second fixing plate 17 is overlapped with the first fixing plate 15, a fixing bolt 16 is threadedly connected between the second fixing plate 17 and the first fixing plate 15, and a sampling device is provided inside the first placement rack 4 and inside the second placement rack 5. Sample bottle 6; one end of the first placement rack 4 is fixedly connected to the second clamping plate 19, one end of the second placement rack 5 is fixedly connected to the first clamping plate 18, one side of the first clamping plate 18 and one side of the second clamping plate 19 are overlapped on one side of the sampling bottle 6; one end of the sampling bottle 6 is provided with a sealing plug 3, one end of the sealing plug 3 is fixedly connected to the movable plate 2, the middle part of the movable plate 2 is threadedly connected to a connecting rod 14, one end of the connecting rod 14 is rotatably connected to one side of the second clamping plate 19, and the other end of the connecting rod 14 passes through one side of the shell 1; one end of the movable plate 2 is slidably connected to the outside of the connecting plate 11.

[0024] When sampling water, the second placement rack 5 is opened, and the sampling bottle 6 is placed in the first placement rack 4. The second placement rack 5 is then rotated so that the second fixing plate 17 on one side overlaps the first fixing plate 15. The fixing bolt 16 is rotated to fix the second fixing plate 17 and the first fixing plate 15. The first clamping plate 18 and the second clamping plate 19 cooperate to position the sampling bottle 6 between the first placement rack 4 and the second placement rack 5. By staggeredly distributing four sampling bottles 6 on both sides of the shell 1, multiple water samples can be sampled at a time, thereby improving the efficiency of dioxin sampling. At the same time, the four sampling bottles 6 are evenly distributed on both sides of the shell 1, which can balance the weight on both sides when lifting after sampling. Example

[0025] like Figure 2 and Figure 3 As shown, one end of the connecting rod 14 is fixedly connected to the slave bevel gear 12, one side of the slave bevel gear 12 is meshed with the main bevel gear 13, and the middle part of the main bevel gear 13 is fixedly connected to the second rotating rod 9; one end of the second rotating rod 9 is rotatably connected to the inner side of the shell 1, the other end of the second rotating rod 9 passes through the other side of the shell 1, and the outside of the second rotating rod 9 is fixedly connected to the second gear 10; one side of the second gear 10 is meshed with the first gear 7, the middle part of the first gear 7 is fixedly connected to the first rotating rod 8, and one end of the first rotating rod 8 is rotatably connected to one end of the shell 1.

[0026] When sampling, by rotating the first rotating rod 8, the first gear 7, the second gear 10 and the second rotating rod 9 are driven to rotate in sequence. Through the engagement of the slave bevel gear 12 and the main bevel gear 13, while the second rotating rod 9 rotates, multiple connecting rods 14 are driven to rotate. The rotation of the connecting rod 14 drives the movable plate 2 to move. The two movable plates 2 on the same side of the shell 1 move synchronously. At the same time, the movable plate 2 slides on the connecting plate 11, and the movement path of the movable plate 2 can be fixed. The movement of the movable plate 2 drives the sealing plug 3 to move. When the sealing plug 3 is separated from the sampling bottle 6, the water enters the sampling bottle 6 for sampling. Then, by flipping the first rotating rod 8, the second gear 10 can be flipped, and the sealing plug 3 moves in the opposite direction to enter the interior of the sampling bottle 6, so that the port of the sampling bottle 6 can be sealed to end sampling.

[0027] The method of use and working principle of the device are as follows: open the second placement rack 5, place the sampling bottle 6 in the first placement rack 4, then rotate the second placement rack 5 so that the second fixing plate 17 on one side overlaps the first fixing plate 15, rotate the fixing bolt 16 to fix the second fixing plate 17 and the first fixing plate 15, and the first clamping plate 18 and the second clamping plate 19 cooperate to position the sampling bottle 6 between the first placement rack 4 and the second placement rack 5, so as to facilitate the fixing of the sampling bottle 6, put the sampling device into the water, and when sampling, rotate the first rotating rod 8 to drive the first gear 7, the second gear 10 and the second rotating rod in turn. The movable rod 9 rotates, and at the same time as the second rotating rod 9 rotates, it drives multiple connecting rods 14 to rotate. The rotation of the connecting rod 14 drives the movable plate 2 to move, and the two movable plates 2 on the same side of the shell 1 move synchronously. At the same time, the movable plate 2 slides on the connecting plate 11, and the movement path of the movable plate 2 can be fixed. The movement of the movable plate 2 drives the sealing plug 3 to move. When the sealing plug 3 is separated from the sampling bottle 6, water enters the sampling bottle 6 for sampling. Then, by flipping the first rotating rod 8, the second gear 10 can be flipped, and the sealing plug 3 moves in the opposite direction to enter the interior of the sampling bottle 6, so that the port of the sampling bottle 6 can be sealed to end the sampling.
