Description

Technical Field

[0001] This utility model relates to the field of water quality testing technology, and in particular to a sample introduction device for phytoplankton detection. Background Technology

[0002] Phytoplankton are a type of tiny plant that floats in water. They produce oxygen and organic matter through photosynthesis and are an important part of aquatic ecosystems. Phytoplankton not only play a key role in maintaining and regulating the aquatic ecological environment, but also play an important role in the global carbon cycle and oxygen production.

[0003] For example, Chinese utility model patent (CN212622651U) discloses an automatic sampling device for phytoplankton detection, relating to the field of water quality testing. This device addresses the problem in existing technologies where different types of phytoplankton require different types of testing, and the manual selection process is cumbersome and inefficient. The device housing has an installation box mounted on top, with temperature control devices on both sides. A sample storage container is mounted on top of the installation box, containing phytoplankton. A fixing box is mounted below the sample storage container. Two movable blocks are mounted on the lower part of the device housing, and a sliding groove is installed below the housing. The two movable blocks are slidably connected to the housing via the sliding groove. A limiting sleeve is mounted above each movable block. Sample storage containers are located inside both the limiting sleeve and the sample storage container. A foot is mounted on the lower part of the device housing.

[0004] However, when the inventors implemented this device, they found the following defects: the sample bottle may tilt during the falling process, which may prevent the sample bottle from falling accurately into the limiting sleeve, thus affecting subsequent detection or sampling operations. Secondly, the prior art cannot shake the sample bottle during use, which may result in uneven water sample and thus inaccurate test results. Utility Model Content

[0005] Therefore, it is necessary to provide a sample introduction device for phytoplankton detection to address the aforementioned technical problems.

When using the device, the translation component can be activated, driving the lifting component to move below the support frame to be lifted and the phytoplankton sample bottle. This allows the lifting component to lift the support frame, thereby raising the phytoplankton sample bottle inside the lifted support frame. This facilitates rapid selection of different phytoplankton for sample introduction and prevents the sample bottle from tilting during descent, thus avoiding any inaccurate landing within the limiting sleeve and ensuring subsequent detection or sampling operations are not affected.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0050] As described in the background section, the sample bottle may tilt during its descent, which may prevent it from accurately falling into the limiting sleeve.

[0051] To solve this technical problem, this utility model provides a sample introduction device for phytoplankton detection, which is applied to phytoplankton detection.

[0052] For details, please refer to Figure 1-5 The sample introduction device specifically includes:

[0053] Fixed frame 1;

[0054] A storage rack 2 is mounted on a fixed frame 1;

[0055] A fixed frame 3 is fixedly installed on the inner wall of the storage rack 2;

[0056] Multiple fixed posts 4 are arranged and fixedly installed on the inner wall of the fixed frame 3 from front to back, and the planktonic sample bottles are inserted into the round holes on the fixed posts 4.

[0057] Multiple support frames 5 are arranged sequentially on the fixed column 4 from left to right, and the planktonic sample bottles are located inside the support frames 5.

[0058] Translation component 7 is installed on the inner bottom wall of the holding rack 2;

[0059] And multiple lifting components 8 arranged sequentially from front to back on the translation component 7 for jacking the support frame 5.

[0060] The phytoplankton detection sampling device provided by this utility model includes a lifting component 8 on the holding rack 2 that can lift the support rack 5, and a translation component 7 that drives the lifting component 8 to move left and right. When using the device, the translation component 7 can be activated to drive the lifting component 8 to move below the support rack 5 to be lifted and the phytoplankton sample bottle, so that the lifting component 8 can lift the support rack 5, thereby causing the phytoplankton sample bottle inside the lifted support rack 5 to rise. This facilitates the rapid selection of different phytoplankton for sampling, and also prevents the sample bottle from tilting during the falling process and failing to fall accurately into the limiting sleeve, thus avoiding affecting subsequent detection or sampling operations.

[0061] Example 1

[0062] Please refer to Figure 1-5 A sample introduction device for phytoplankton detection, comprising:

[0063] A storage rack 2 is mounted on a fixed frame 1;

[0064] A fixed frame 3 is fixedly installed on the inner wall of the storage rack 2;

[0065] Multiple fixed posts 4 are arranged and fixedly installed on the inner wall of the fixed frame 3 from front to back, and the planktonic sample bottles are inserted into the round holes on the fixed posts 4.

[0066] Multiple support frames 5 are arranged sequentially on the fixed column 4 from left to right, and the planktonic sample bottles are located inside the support frames 5.

[0067] Translation component 7 is installed on the inner bottom wall of the holding rack 2;

[0068] And multiple lifting components 8 arranged sequentially from front to back on the translation component 7 for jacking the support frame 5.

[0069] The sampling device provided by this utility model, when in use, moves the lifting component 8 to the support frame 5 to be lifted and the plankton sample bottle by the translation component 7. Then, the lifting component 8 is activated and raised. The rising lifting component 8 lifts the support frame 5, thereby raising the plankton sample bottle inside the lifted support frame 5. This facilitates the rapid selection of different plankton for sampling. At the same time, it can also prevent the sample bottle from tilting during the falling process and failing to fall accurately into the limiting sleeve, thus avoiding affecting subsequent detection or sampling operations.

[0070] Specifically, such as Figure 1 and Figure 5 As shown, the lifting assembly 8 includes a first fixed frame 81 fixedly installed on the translation assembly 7. An electric telescopic rod 82 is fixedly installed on the inner bottom wall of the first fixed frame 81, and a second fixed frame 83 is fixedly installed on the top of the electric telescopic rod 82.

[0071] With the above structural design, when the support frame 5 needs to be lifted, the electric telescopic rod 82 inside the first fixed frame 81 drives the second fixed frame 83 to rise, so that the second fixed frame 83 can lift the support frame 5, thereby causing the plankton sample bottle inside the lifted support frame 5 to rise. This facilitates the rapid selection of different plankton for sampling and prevents the sample bottle from tilting during the descent and failing to fall accurately into the limiting sleeve, thus avoiding affecting subsequent testing or sampling operations.

[0072] Specifically, such as Figure 1 and Figure 5 As shown, the translation component 7 includes an H-shaped frame 71 fixedly installed on the inner bottom wall of the holding rack 2. A threaded rod 72 is provided on the inner side of the H-shaped frame 71, and both ends of the threaded rod 72 are rotatably installed between the H-shaped frame 71 and the outer side wall of the threaded rod 72 is threadedly connected to a U-shaped frame 73. A first fixing frame 81 is fixedly installed on the bottom of the U-shaped frame 73. A first motor 74 is fixedly installed on one side of the H-shaped frame 71, and the output end of the first motor 74 is fixedly connected to the threaded rod 72. Both ends of the U-shaped frame 73 are provided with grooves, and a first roller 13 is provided in each of the two grooves. The first roller 13 is rotatably installed on the U-shaped frame 73.

[0073] With the above structural design, when the lifting component 8 needs to lift the support frame 5, the first motor 74 drives the threaded rod 72 to rotate. Then, the rotating threaded rod 72 drives the U-shaped frame 73 threaded on its outer wall, so that the U-shaped frame 73 can move easily and smoothly with the cooperation of the first roller 13. This can drive the position of the lifting component 8 to move, so that the lifting component 8 can move to the bottom of the support frame 5 to be lifted and the planktonic sample bottle.

[0074] Example 2

[0075] Based on Example 1, the sample introduction device for phytoplankton detection provided in Example 1 is further optimized, specifically, as follows: Figure 1-5 As shown, multiple first mounting brackets 9 are fixedly installed at the bottom of the fixed frame 3 from left to right. Hollow tubes 10 are fixedly installed through each of the multiple first mounting brackets 9, and planktonic sample bottles are inserted into the inside of the hollow tubes 10. Rubber pads 11 are fixedly installed on the inner bottom walls of multiple support frames 5, and arc grooves are opened on the top of multiple rubber pads 11.

[0076] Through the above structural design, it is possible to prevent the plankton sample bottle from rising too high due to the support frame 5, which would cause the plankton sample bottle to fall off the fixed column 4. At the same time, it can also provide cushioning protection for the plankton sample bottle, preventing damage due to vibration when the plankton sample bottle is placed in the fixed column 4 and its bottom contacts the support frame 5.

[0077] Example 3

[0078] Based on Example 1, the sample introduction device for phytoplankton detection provided in Example 1 is further optimized, specifically, as follows: Figure 1-6 As shown, a shaking mechanism 6 is provided on the fixed frame 1, and the shaking mechanism 6 is connected to the holding rack 2. The shaking mechanism 6 includes a second mounting bracket 61 fixedly installed on the fixed frame 1, and a driving mechanism 62 is provided at the bottom of the second mounting bracket 61. A strip plate 63 is fixedly installed at the top of the driving mechanism 62, and a connecting column 64 is fixedly installed at the top of the strip plate 63. A rectangular frame 65 is fixedly installed at the bottom of the holding rack 2, and the top of the connecting column 64 is inserted into the rectangular frame 65.

[0079] With the above structural design, when the translation component 7 and the lifting component 8 are not used to drive the support frame 5 to rise, the drive mechanism 62 drives the strip plate 63, so that the strip plate 63, with the cooperation of the connecting column 64 and the rectangular frame 65, can drive the holding rack 2 on the fixed frame 1 to move back and forth, thereby shaking the sample bottle, so that the water sample is uniform and avoids inaccurate test results.

[0080] Specifically, such as Figure 1 and Figure 6 As shown, the drive mechanism 62 includes a second motor 6201 fixedly mounted at the bottom of the second mounting bracket 61 via a motor frame. The output end of the second motor 6201 is fixedly mounted on a fixed plate 6202 through one side wall of the second mounting bracket 61, and a strip plate 63 is fixedly mounted on the top of the fixed plate 6202.

[0081] With the above structural design, when the strip plate 63 is to be rotated, the second motor 6201 drives the fixed disk 6202 to rotate, thereby enabling the strip plate 63 to rotate, and thus enabling the connecting column 64 to drive the holding rack 2 to move back and forth through the rectangular frame 65.

[0082] Specifically, such as Figure 1 and Figure 6 As shown, the top of the holding rack 2 has two pairs of mounting openings, and the inner side of each pair of mounting openings is provided with a second roller 12, which is rotatably mounted on the holding rack 2.

[0083] Through the above structural design, when the holding rack 2 moves on the fixed frame 1, the friction between the holding rack 2 and the fixed frame 1 can be reduced by the second roller 12.

[0084] The automatic column-passing device provided by this utility model is used as follows: The first motor 74 is controlled by an external controller to drive the threaded rod 72 to rotate. Then, the rotating threaded rod 72 drives the U-shaped frame 73 threaded on its outer wall, thereby moving the position of the first fixed frame 81. This allows the second fixed frame 83 to move to the bottom of the support frame 5 and the plankton sample bottle to be lifted. Then, the second fixed frame 83 is lifted by the electric telescopic rod 82, thereby lifting the support frame 5. This causes the plankton sample bottle inside the lifted support frame 5 to rise. At the same time, under the action of the first mounting frame 9 and the hollow tube 10, the support frame 5 can be prevented from lifting the plankton sample bottle too high, which would cause the plankton sample bottle to fall off the fixed column 4. Afterwards, when the translation component 7 and the lifting component 8 are not used to lift the support frame 5, the second motor 6201 drives the fixed plate 6202 to rotate, thereby allowing the strip plate 63 to rotate. This allows the connecting column 64 to drive the holding rack 2 to move back and forth through the rectangular frame 65.
