Description

Technical Field

[0001] The present invention relates to the technical field of sample collection and storage, and in particular to a storage device for environmental monitoring with a sample extraction function. Background Art

[0002] In the process of monitoring the environment, samples will be collected from water sources or soil in the monitoring area, and then the sampled samples will be tested. At present, when collecting water sources or soil in the monitoring environment, different equipment will be used for collection, and then the collected samples will be transferred to a storage device. By transferring the device for storing samples, the testers can test the samples and determine the environmental conditions through the tested samples, thereby performing environmental testing. However, in different environments, such as the collected soil, there will be stratification. When it is taken out of the sampling device and then placed in the storage device, it will cause confusion between the stratification layers of the soil, and the chaotic soil layers will affect the detection of the testers. At the same time, when the collected liquid is stored in the sample, the liquid will be poured out to make the internal division of the liquid chaotic. At the same time, the liquid is prone to shaking during transfer. When the sampling amount is large, the liquid will be chaotic due to shaking during sample transfer, which will disrupt the accuracy of liquid detection. Summary of the invention

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0019] Example 1 To avoid stratification problems in sampled samples, refer to Figure 1-Figure 6 As shown, the purpose of this embodiment is to provide a storage device for environmental monitoring with a sample extraction function, including a storage element 1, the interior of the storage element 1 is used to store the sampled sample, and the interior of the storage element 1 is provided with a partition 2, the partition 2 divides the interior of the storage element 1 into a plurality of chambers, and when the partition 2 moves downward, the storage element 1 is driven to move downward, so that the storage element 1 and the partition 2 are both inserted into the sample to be collected, and a protective element 3 is provided on the outside of the storage element 1, and a blocking element 4 is provided near the lower end of the protective element 3 to seal The blocking member 4 is sleeved on the storage member 1, and the protective member 3 protects the blocking member 4. When the partition 2 rotates, it drives the protective member 3 to rotate. The rotating protective member 3 pushes the blocking member 4 to the lower side of the storage member 1, so that one end of the blocking member 4 extends to the bottom of the storage member 1, and the blocking member 4 extending to the bottom of the storage member 1 is turned toward the central axis of the storage member 1. During the turning of the blocking member 4, the partition 2 is pulled up to limit the turning position of the blocking member 4, so that the blocking member 4 and the partition 2 cooperate to block the bottom of the storage member 1.

[0020] When collecting samples, one end of the partition 2 is inserted into the sample, and then the sample is cut through the storage member 1, so that the device is inserted into the sample to collect the sample. At the same time, when the collection is completed, the partition 2 is rotated to drive the protective member 3 to rotate, and the rotating protective member 3 drives the blocking member 4 to penetrate the sample. At the same time, the storage member 1 is lifted to make the blocking member 4 shrink inward, and then the partition 2 moves upward to guide the blocking member 4, so that the blocking member 4 and the partition 2 seal the bottom of the storage member 1, so that the device completes the sampling and storage of the device. When collecting soil, the trouble of transferring soil is avoided, and when collecting liquid, the trouble of pouring liquid is avoided, so as to ensure that the stratification of the sample will not be disrupted, thereby improving the accuracy of sample detection.

[0021] In order to make the above structure achieve the above described effect, please refer to Figure 1-Figure 14As shown, the storage element 1 includes a storage tube 11, and the partition element 2 includes a plurality of partition plates 21 in an annular array. The partition plates 21 are arranged inside the storage tube 11, and the side walls of the partition plates 21 are in contact with the side walls of the storage tube 11, so that the plurality of partition plates 21 divide the interior of the storage tube 11 into a plurality of chambers. At the same time, a plurality of side cabinet bars 12 corresponding to the positions of the partition plates 21 are fixed on the inner wall of the storage tube 11, and clamping bars 13 are fixed on the tops of the plurality of side cabinet bars 12. The partition plates 21 are slidably arranged in the clamping bars 13, and the side edges of the partition plates 21 are slidably arranged in the side cabinet bars 12. The position of the partition plates 21 is limited by the side cabinet bars 12 and the clamping bars 13, so that the partition plates 21 can only move up and down inside the storage tube 11, thereby improving the sliding movement of the partition plates 21 inside the storage tube 11. In order to ensure the stability of movement, a middle tube 14 is fixed between several clamping bars 13, and a middle sliding column 25 is fixed on the upper side of the connection position of several partition plates 21. The middle sliding column 25 is slidably arranged inside the middle tube 14, and a sliding groove for the partition plates 21 to move up and down is opened on the middle tube 14. When the partition plates 21 move upward, the middle tube 14 will block the upward position of the partition plates 21. The space for the partition plates 21 to move in the storage tube 11 is controlled by blocking the upward position of the partition plates 21 by the middle tube 14. One end of the middle sliding column 25 passes through the upper end of the middle tube 14 and is fixed with a connecting column 26. The upper end of the connecting column 26 is threadedly connected to a connecting head 291, and a pull rod 292 is rotatably connected to the connecting head 291. The user pulls or presses the pull rod 292 to make the pull rod 292 press or pull up the connecting column 26.

[0022] When soil needs to be collected, the storage tube 11 is placed on the soil, and then the pull rod 292 is pressed. The pull rod 292 under pressure drives the partition plate 21 to press into the soil. A retaining ring 24 is fixed near the top of several partition plates 21. During the downward movement of the partition plates 21, the retaining ring 24 presses the top of the storage tube 11, so that the storage tube 11 is penetrated into the soil together with the partition plates 21. In order to facilitate the penetration of the partition plates 21 into the soil, the bottom of the partition plates 21 is an inclined surface inclined to the axis of the storage tube 11, and several partition plates 21 are provided. A spike 22 is fixed at the bottom of the plate 21. When the partition plate 21 is forced to move downward, the spike 22 first penetrates into the soil, and then the partition plate 21 divides the soil. Then the storage tube 11 cuts the soil, allowing the soil to enter the chamber between the storage tube 11 and the partition plate 21. When the device needs to continue to move downward, the device needs to be repeatedly inserted into the soil and then the soil is taken out. If the soil needs to be fully collected, after the soil is collected in the storage tube 11, the device that has completed the soil collection is extracted, and then a new device is replaced to continue collecting.

[0023] When liquid needs to be collected, a floating object is tied to the storage tube 11. The floating object can be a foam block or a plastic bottle. The storage tube 11 is pulled by the buoyancy of the foam block or the plastic bottle, so that the storage tube 11 can resist gravity and move the partition 2 downward, thereby ensuring that the partition plate 21 can guide the debris in the liquid to the surroundings.

[0024] After the storage tube 11 has collected soil or liquid, the liquid or soil will be pulled upward. When collecting soil, the soil will fall down, resulting in the loss of soil stratification. When collecting liquid, the liquid will flow through the storage tube 11 during the upward movement of the storage tube 11. At this time, the liquid in the corresponding water area cannot be collected. In order to ensure that the liquid or soil collected in the storage tube 11 is not lost, the structure of the protective member 3 and the sealing member 4 is refined.

[0025] Please refer to Figure 7-Figure 14 The protective member 3 includes a rotating collar 31, which is sleeved on a position near the upper end of the storage tube 11. A plurality of outer rings 18 are fixed on an outer wall of the storage tube 11 near the top. An inner ring groove 33 is provided on the inner wall of the rotating collar 31. The outer ring 18 is slidably arranged in the inner ring groove 33. A plurality of rotating blocks 16 are fixed centrally and symmetrically on the outer ring 18. At the same time, a limiting arc groove 35 is centrally and symmetrically provided on the side wall of the inner ring groove 33. The rotating block 16 is slidably arranged inside the limiting arc groove 35. The limiting arc groove 35 limits the rotating block 16 to rotate 90 degrees in the limiting arc groove 35. At the same time, a protective collar 32 is rotatably connected to the rotating collar 31 near the bottom. A sliding chamber is provided between the protective collar 32 and the storage tube 11. The blocking member 4 is provided in the sliding chamber. The blocking member 4 includes a lowering tube 41, which is slidably sleeved on the storage tube 11, and the outer wall of the lowering tube 41 and the protective The inner wall of the protective sleeve ring 32 is in sliding contact, and a plurality of vertical sliding grooves 43 are provided inside the lower slide tube 41. A plurality of sliding limit blocks 17 are fixed at a position near the bottom of the outer wall of the storage tube 11. The sliding limit blocks 17 are slidably arranged in the vertical sliding grooves 43. The vertical sliding grooves 43 limit the movement trajectory of the sliding limit blocks 17, so that the lower slide tube 41 can move up and down between the storage tube 11 and the protective sleeve ring 32. At the same time, inclined arc surfaces are provided on the upper side of the lower slide tube 41 and the bottom of the rotating sleeve ring 31. The inclined surface is a trajectory with one end high and the other end low, and its shape is elliptical. When the lower slide tube 41 is inside the protective sleeve ring 32, the bottom of the rotating sleeve ring 31 and the top of the lower slide tube 41 are in close contact. When the rotating sleeve ring 31 rotates, the inclined arc surface of the rotating sleeve ring 31 squeezes the inclined arc surface of the lower slide tube 41, so that one end of the lower slide tube 41 extends downward from the protective sleeve ring 32.

[0026] A plurality of sealing pieces 42 are hingedly connected in an annular array at the bottom of the lower slide tube 41. An elastic rubber ring 44 is provided at the connection position of the lower slide tube 41 and the sealing piece 42 to cover the gap between the lower slide tube 41 and the sealing piece 42. A torsion spring is provided at the hinged position of the sealing piece 42 and the lower slide tube 41. The torsion spring drives one end of the sealing piece 42 to rotate toward a position close to the central axis of the lower slide tube 41, so that the side walls of the plurality of sealing pieces 42 are close to each other. At the same time, an inclined guide bar 23 is fixed on the inclined surface at the bottom of the partition plate 21. When the sealing piece 42 is tilted, the partition plate 21 moves upward, so that the inclined guide bar 23 guides the end of the sealing piece 42, so that the plurality of sealing pieces 42 and the thorn head 22 seal the bottom of the storage tube 11. At this time, the plurality of sealing pieces 42 cooperate with the partition plate 21 to seal the bottom of the storage tube 11, so as to prevent the collected soil and liquid from falling out of the storage tube 11.

[0027] The limiting tube 27 is rotatably arranged on the top ring 15, and when the pull rod 292 drives the connecting column 26 to move downward, the rotating block 29 slides inside the limiting tube 27. At the same time, a rotating frame 28 is fixed at the bottom of the limiting tube 27. The shape of the rotating frame 28 is the same as the cross-sectional shape of the combination of several partition plates 21 and the retaining ring 24. At the same time, several rotating bars 281 are fixed at the bottom of the rotating frame 28 near the edge. Several rotation limiting grooves 34 corresponding to the rotating bars 281 are provided on the outer side wall of the rotating ring 31 near the top. One end of the rotating bar 281 is slidably inserted into the In the rotation limiting groove 34, by rotating the rotating block 29, the rotating block 29 drives the limiting tube 27 and the rotating frame 28 to rotate, and the rotating rotating frame 28 drives the rotating ring 31 to rotate by plugging the rotating bar 281 and the rotation limiting groove 34. When the rotating ring 31 rotates, the lower slide tube 41 is pushed downward. When the storage tube 11 penetrates into the soil or liquid, the soil or liquid will enter the gap between the protective ring 32 and the storage tube 11. The downwardly moved lower slide tube 41 pushes the soil and liquid out from between the protective ring 32 and the storage tube 11, and then the blocking piece 42 rotates and moves upward by pulling the partition 2 so that the blocking piece 42 is guided by the inclined guide bar 23, so that the side wall between the blocking piece 42 and the partition plate 21 contacts, so that the soil or liquid entering the storage tube 11 is blocked in the storage tube 11, and the soil or liquid is prevented from falling. At the same time, this scheme can be used as a transportation device directly to avoid the stratification and confusion during sample storage.
