DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4 A water quality detection sampling device includes a counterweight block 1 and a sampling device body 2, the top of the counterweight block 1 is fixedly connected to the sampling device body 2, and the top of the sampling device body 2 is fixedly connected to a filter sleeve 3, the top of the filter sleeve 3 is fixedly and movably connected to a fixed collar 4, and the top of the fixed collar 4 is fixedly connected to a fixed sleeve rod 5, a movable pull rod 6 is inserted into the interior of the fixed sleeve rod 5, and the bottom end of the movable pull rod 6 is fixedly connected to a sealing plug 15.

[0022] Further, see Figure 2 It can be known that the two sides of the fixed ring 4 are symmetrically fixedly connected with the fixed frame 7, and an extension rod 9 is inserted into the interior of the fixed frame 7, the end of the extension rod 9 away from the interior of the fixed frame 7 is fixedly connected with a fixed ring 8, and the bottom end of the fixed ring 8 is fixedly connected with a cleaning rod 10, and the fixed ring 8 moves inside the fixed frame 7, so as to facilitate the adjustment of the length to adapt to the diameter of the filter sleeve 3.

[0023] Further, see Figure 2 It can be known that a second spring 17 is inserted into the interior of the fixed frame 7, and one end of the second spring 17 is connected to the inner wall of the fixed frame 7, and the other end of the second spring 17 is fixedly connected to the extension rod 9. The second spring 17 is in an expanded state. During use, the second spring 17 uses its own contraction force to pull the cleaning rod 10 to always contact the surface of the filter sleeve plate 3, which facilitates better cleaning.

[0024] Further, see Figure 3 and Figure 4 It can be known that the top end of the sealing plug 15 is symmetrically fixedly connected to the limit rod 14, and the surface of the limit rod 14 is sleeved with a limit sleeve 12, the outer wall of the limit sleeve 12 is fixedly connected to a connecting rod 16, and the end of the connecting rod 16 away from the limit sleeve 12 is fixedly connected to the inner wall of the filter sleeve plate 3. During use, the limit sleeve 12 can limit the limit rod 14 to facilitate its straight line up and down movement.

[0025] Further, see Figure 3 It can be known that the top end of the limit rod 14 is fixedly connected to the limit block 11, and the diameter of the limit block 11 is larger than the diameter of the limit sleeve 12. During use, the limit block 11 can play a limiting role to prevent the limit rod 14 from detaching from the limit sleeve 12.

During use, when the first spring 13 is subjected to tension, the first spring 13 is in an expanded state, which facilitates the downward movement of the sealing plug 15. When the external force is released, the first spring 13 contracts and pulls the sealing plug 15 to return to its original position, thereby playing a sealing role.

[0027] Working principle: When the utility model is in use, according to the attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 and attached Figure 4 As shown, during use, the sampling device body 2 is put into water. When it reaches a certain depth, the movable pull rod 6 is manually pushed, and the movable pull rod 6 moves downward. The movable pull rod 6 pushes the sealing plug 15 to move downward. During the downward movement of the sealing plug 15, the first spring 13 is pulled to an expanded state, and the water flows through the filter sleeve 3 to filter into the interior of the sampling device body 2 for sampling;

[0028] After the sampling is completed, the external force of the movable pull rod 6 is released, the first spring 13 contracts and drives the sealing plug 15 to reset, thereby sealing the gap at the top of the sampling device body 2, and pulling the sampling device body 2 upward to complete the sampling;

[0029] After sampling is completed, the operator rotates the fixed sleeve rod 5, the fixed sleeve rod 5 drives the fixed sleeve ring 4 to rotate, the fixed sleeve ring 4 drives the fixed frame 7 to rotate, the fixed frame 7 drives the extension rod 9 to rotate, the extension rod 9 drives the fixed ring 8 to rotate, the fixed ring 8 rotates and drives the cleaning rod 10 to rotate, the cleaning rod 10 rotates to clean the outer wall of the filter sleeve plate 3, so as to avoid clogging of the filter holes of the filter sleeve plate 3, and the operation is completed. The above is the entire working principle of the utility model.
