Detailed implementation manners
[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will describe the implementation manners of the present utility model in detail with reference to the accompanying drawings. However, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0026] As Figures 1 - 6 shown, this embodiment provides a turbid water sampler, including a sampling pipe 1, a sample storage bin 2, and a temporary storage bin 3.
[0027] Specifically, as Figure 2 shown, both the upper and lower ends of the sampling pipe 1 are open - set. Two spaced - apart sealing discs 11 are coaxially movably arranged on the central axis of the sampling pipe 1. The radius of the sealing disc 11 matches the inner diameter of the sampling pipe 1. More specifically, when the sealing disc 11 moves in the sampling pipe 1, the contact surface between the sealing disc 11 and the inner wall of the sampling pipe 1 has airtightness.
[0028] Specifically, as Figure 2 and Figure 4As shown in the figure, the upper end of the sampling tube 1 is connected to the inside of the sample storage bin 2 through the lower end of the sample storage bin 2. The upper end of the sample storage bin 2 is coaxially penetrated with an opening 21 through the sampling tube 1. The opening 21 matches the radius of the sealing disc 11. More specifically, the opening 21 is used to enable the sealing disc 11 to move upward out of the sample storage bin 2. The lower end of the sample storage bin 2 is also penetrated with a drain port 22.
[0029] Specifically, as Figure 4 and Figure 6 shown, the temporary storage bin 3 is coaxially and movably arranged below the drain port 22. The upper end of the temporary storage bin 3 is open. The lower end of the temporary storage bin 3 is coaxially connected with a drain pipe 31. A sealing column 32 is coaxially and movably arranged in the temporary storage bin 3. The radius of the sealing column 32 matches the inner diameter of the drain pipe 31. More specifically, when the lower end of the sealing column 32 moves into the drain pipe 31, the contact surface between the sealing column 32 and the inner wall of the drain pipe 31 has airtightness.
[0030] Specifically, as Figure 4 shown, the sieve ring 4 is coaxially fitted to the upper end of the temporary storage bin 3. A sieve mesh 41 is arranged in the sieve ring 4. The sieve mesh 41 is used to screen out impurities in the water body; more specifically, the fitting part between the sieve ring 4 and the upper end of the temporary storage bin 3 has airtightness. When the temporary storage bin 3 moves to contact with the sieve ring 4 and the sample storage bin 2, the contact surface between the sieve ring 4 and the sample storage bin 3 has airtightness.
[0031] During operation, insert the lower end of the sampling tube 1 into the water body, and move the two sealing discs 11 so that one of the sealing discs 11 moves out of the lower end of the sampling tube 1 and into the water body, and the other sealing disc 11 moves to the lower end of the sampling tube 1; move the two sealing discs 11 upward so that the water body enters the sampling tube 1 from the lower end of the sampling tube 1.
[0032] When one of the sealing discs 11 enters the sampling tube 1 from the lower end of the sampling tube 1, continue to move the two sealing discs 11 upward so that the other sealing disc 11 enters the sample storage bin 2 and leaves the sample storage bin 2 through the opening 21. The water body between the two sealing discs 11 enters the sample storage bin 2 and passes through the drain port 22, the sieve mesh 41, the temporary storage bin 3, and the drain pipe 31 in sequence. Place the storage container below the drain pipe 31 in sequence to receive the water body, and the sampling is completed.
[0033] Preferably, as Figure 1 , Figure 2 , Figure 4 , Figure 6As shown, a connecting rod 12 is connected between the sealing discs 11. The opening 21 is coaxially communicated with a vertical pipe 23, and the upper end of the vertical pipe 23 is communicated with a gas pump 24. During operation, the lower end of the sealing column 32 is inserted into the drain pipe 31, and the temporary storage bin 3 is lifted upward so that the screening ring 4 contacts the sample storage bin 2. At this time, the movement of the two sealing discs 11 can be driven by controlling the air pressure through the gas pump 24. When drainage is required, the sealing column 32 is moved upward so that the lower end of the sealing column 32 leaves the drain pipe 31. Since the diameter of the drain pipe 31 is large enough, the water body can flow out from the lower end of the drain pipe 31.
[0034] Preferably, as Figure 4 and Figure 5 shown, a first annular groove 25 is coaxially provided on the lower surface of the sample storage bin 2 at the drainage port 22, a second annular groove 33 is coaxially provided at the upper end of the temporary storage bin 3, and mating rings 42 are coaxially provided on both the upper and lower surfaces of the screening ring 4. The sizes of the mating rings 42, the first annular groove 25, and the second annular groove 33 match. Specifically, the two mating rings 42 are respectively used to extend into the first annular groove 25 and the second annular groove 33, and the contact surfaces of the mating rings 42 with the first annular groove 25 and the second annular groove 33 have airtightness.
[0035] Preferably, as Figure 4 and Figure 5 shown, a mating block 26 is connected to the outer wall of the sample storage bin 2. A sliding column 27 is slidably sleeved along the axial direction of the temporary storage bin 3 in the mating block 26. The lower end of the sliding column 27 is connected with a mounting block 34, and the mounting block 34 is arranged on the outer wall of the temporary storage bin 3. A first spring 28 is coaxially arranged on the periphery of the sliding column 27, and the upper and lower ends of the first spring 28 are respectively connected with the mating block 26 and the mounting block 34. The first spring 28 is always in a stretched state. During operation, the temporary storage bin 3 is pulled downward, the screening ring 4 is taken out from between the sample storage bin 2 and the temporary storage bin 3 and the screen 41 is cleaned. After cleaning, the screening ring 4 is placed back between the sample storage bin 2 and the temporary storage bin 3. At this time, the sample storage bin 2 and the temporary storage bin 3 clamp the screening ring 4 under the action of the first spring 28. At the same time, the two mating rings 42 cooperate with the first annular groove 25 and the second annular groove 33. Such a design can conveniently take out the screening ring 4 from the device and clean the screen 41, avoiding the accumulation of impurities on the screen 41.
[0036] Preferably, as Figure 4 and Figure 6As shown in the figure, a sealing disc 35 is coaxially connected to the upper end of the sealing column 32, and the contact between the sealing disc 35 and the lower surface inside the temporary storage bin 3 has airtightness; a convex block 36 is connected to the circumferential side of the sealing disc 35. In this example, two convex blocks 36 are provided in total; the convex blocks 36 are each connected with a sliding rod 37 along the axial direction of the temporary storage bin 3. Two sliding holes 38 are penetrated through the lower end of the temporary storage bin 3, and the sliding rods 37 are slidably fitted into the sliding holes 38 in a one-to-one correspondence. A second spring 39 is coaxially provided on the circumferential side of each sliding rod 37. The upper and lower ends of the second spring 39 are respectively connected to the convex block 36 and the lower end of the temporary storage bin 3. The lower end of the sliding rod 37 is connected with a pressing ring 310 coaxially arranged with the temporary storage bin 3. When the second spring 39 is in its original state, the lower end of the sealing column 32 extends into the drain pipe 31; when sampling is required, the upper end of the storage container is brought into contact with the pressing ring 310 and the pressing ring 310 is pushed upward. At this time, the pressing ring 310 drives the sealing column 32 to move upward through the sliding rod 37, the convex block 36, and the sealing disc 35, so that the lower end of the sealing column 32 leaves the drain pipe 31, and the water body flows from the drain pipe 31 into the storage container; after sampling is completed, the storage container is removed, and the sealing column 32 re-enters the drain pipe 31 under the action of the second spring 39.
[0037] Preferably, as Figure 1 , Figure 3 , Figure 6 shown, the device further includes a bottle-carrying mechanism 5. The bottle-carrying mechanism 5 includes a turntable 51, a lifting ring 52, and a bottle-sleeving ring 53. The turntable 51 is arranged below the temporary storage bin 3 along the axial direction of the temporary storage bin 3, and the turntable 51 is rotatably arranged around its own central axis. The lifting ring 52 is coaxially and movably arranged above the turntable 51. The bottle-sleeving ring 53 is arranged along the axial direction of the turntable 51 and is circumferentially arrayed with a plurality of around the central axis of the turntable 51. In this example, six bottle-sleeving rings 53 are arrayed. The bottle-sleeving ring 53 is used to fix the storage container; the bottle-sleeving rings 53 are all arranged directly above the upper surface of the lifting ring 52. The distance between the bottle-sleeving ring 53 and the central axis of the turntable 51 is equal to the distance between the temporary storage bin 3 and the central axis of the turntable 51, so that the storage container sleeved into the bottle-sleeving ring 53 can be successively located directly below the drain pipe 31 under the rotation of the turntable 51; the bottle-sleeving rings 53 are all connected with support rods 54, and the support rods 54 are connected to the turntable 51; during operation, the storage container is sleeved into the bottle-sleeving ring 53, and the bottom of the bottle-sleeving ring 53 is placed on the lifting ring 52. The turntable 51 is rotated to make the storage container successively located directly below the drain pipe 31, and the lifting ring 52 is raised to make the upper end of the storage container push the pressing ring 310 upward.
[0038] Preferably, as Figure 3As shown in the figure, an installation plate 29 is provided on the upper surface of the sample storage bin 2. A rotation motor 210 is provided on the installation plate 29. The drive shaft of the rotation motor 210 is coaxially connected to a rotation rod 211. The rotation rod 211 is coaxially connected to a turntable 51. The rotation motor 210 is used to drive the turntable 51 to rotate through the rotation rod 211. A linear cylinder 55 is provided on the turntable 51 along its axial direction. The drive shaft of the linear cylinder 55 is connected to a lifting ring 52. The linear cylinder 55 is used to drive the lifting ring 52 to lift and lower.
