Description

Technical Field

[0001] This utility model relates to the field of environmental protection technology, and in particular to a sampling device for detecting blue-green algae in lakes. Background Technology

[0002] With the increasing severity of global water environment problems, eutrophication of water bodies is particularly prominent, and cyanobacterial pollution has gradually become a key focus in water quality monitoring and environmental protection. Cyanobacteria not only affect the transparency of water bodies and reduce water quality, but may also release toxic substances, causing harm to aquatic organisms, the ecological environment and human health. Therefore, the monitoring and detection of cyanobacteria is of particular importance.

[0003] Currently, there are various types of sampling devices for detecting cyanobacteria in lakes on the market. However, these devices use complex mechanical devices to collect samples, which requires a lot of time and manpower, resulting in low work efficiency. Furthermore, after sampling, it is difficult to effectively separate the cyanobacteria from the water sample, leading to excessive impurities in the cyanobacteria sample and affecting the test results. Utility Model Content

[0004] This invention addresses the problem that some devices on the market use complex mechanical devices for sampling, which requires a lot of time and manpower to complete the sampling, resulting in low work efficiency. Furthermore, after sampling, it is difficult to effectively separate cyanobacteria from water samples, leading to excessive impurities in the cyanobacteria samples and affecting the test results. Therefore, this invention provides a sampling device for detecting cyanobacteria in lakes.

[0005] This utility model is achieved using the following technical solution: a sampling device for detecting cyanobacteria in lakes, comprising a main body, a limiting mechanism, and an auxiliary mechanism. The limiting mechanism is located inside the main body, and the auxiliary mechanism is located at the bottom of the main body. The main body includes a shell, with fixed columns fixedly connected to both sides of the shell. A lifting ring is rotatably connected to the outer side of each fixed column. A sealing cover is installed on the top of the shell, with a limiting cover threaded inside the sealing cover. Fixed blocks are fixedly connected to both sides of the bottom of the sealing cover, and a support frame is fixedly connected to the bottom of the sealing cover. A filter screen is installed on the surface of the support frame, and a sealing ring is provided on the surface of the limiting cover. The fixed blocks are located outside the support frame, the sealing ring is located at the upper end of the surface of the limiting cover, and the support frame is located inside the shell.

[0006] Through the above technical solution, the limiting mechanism is used to limit the sealing cover, the auxiliary mechanism is used to limit the support frame, and the filter screen is used to effectively separate the blue-green algae and the water sample.

[0007] As a further improvement to the above solution, the limiting mechanism includes inclined blocks that are slidably connected to the inner walls of both sides of the housing. A cylinder is fixedly connected to the outer side of each inclined block. A spring is sleeved on the outer side of each cylinder. A limiting block is fixedly connected to the outer side of each cylinder. A ring is rotatably connected to the outer side of each limiting block. A limiting plate is slidably connected to the lower end of each inclined block. A support column is fixedly connected to the lower end of each limiting plate. A spring is fixedly connected to the lower end of each support column.

[0008] With the above technical solution, when the fixing block is inside the shell, the inclined block can limit the fixing block, and by pulling the ring, the inclined block can be moved outward, thereby unlocking the sealing cover.

[0009] As a further improvement to the above solution, the auxiliary mechanism includes a baffle that is slidably connected to the bottom of the support frame, a rotating plate that is rotatably connected to the bottom of the support frame, a protruding plate that is fixedly connected to the bottom of the housing, an auxiliary plate that is fixedly connected to the bottom of the baffle, and the baffle being located inside the rotating plate.

[0010] Through the above technical solution, the protruding plate at the bottom of the housing is used to limit the rotating plate and prevent the rotating plate from shaking inside the housing, which would cause the baffle to loosen.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This utility model, by setting a limiting mechanism, causes the ring to be pulled, which in turn moves the limiting block, cylinder, and inclined block outward together, thereby releasing the limiting of the sealing cover. After the inclined block releases its limiting of the fixing block, the second spring extends, pushing the fixing block and causing the sealing cover to be pushed upward by a portion, so that the fixing block is pushed out of the upper part of the sealing cover. This makes it easier for workers to remove the sealing cover, thereby saving time and labor intensity, ensuring that the equipment is used more efficiently and conveniently, and further improving work efficiency.

[0013] This invention incorporates an auxiliary mechanism. By rotating a rotating plate, the operator can release the baffle, allowing it to be extracted and the blue-green algae inside the filter screen to be removed. The water sample containing the blue-green algae is located inside the casing. The operator can effectively separate the blue-green algae and the water sample for separate testing, enabling a better understanding of the blue-green algae and timely identification of potential water quality problems, thus improving the overall effectiveness.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0023] Example:

[0024] Please combine Figure 1-6This embodiment of a sampling device for detecting cyanobacteria in lakes includes a main body 1, a limiting mechanism 2, and an auxiliary mechanism 3. The limiting mechanism 2 is located inside the main body 1, and the auxiliary mechanism 3 is located at the bottom of the main body 1. The main body 1 includes a housing 11, with fixed posts 12 fixedly connected to both sides of the housing 11. A lifting ring 13 is rotatably connected to the outer side of the fixed posts 12. A sealing cover 14 is installed on the top of the housing 11. A limiting cover 15 is threadedly connected inside the sealing cover 14. Fixed blocks 17 are fixedly connected to both sides of the bottom of the sealing cover 14, and a support frame 18 is fixedly connected to the bottom of the sealing cover 14. A filter screen 19 is installed on the surface of the support frame 18, and a sealing ring 16 is provided on the surface of the limiting cover 15. The fixing block 17 is located on the outside of the support frame 18, and the sealing ring 16 is located at the upper end of the surface of the limiting cover 15. The support frame 18 is located inside the shell 11. The staff can open the limiting cover 15 by rotating the protruding plate at the upper end of the limiting cover 15, so that they can hold the lifting ring 13 or tie it with a rope and put it into the lake for cyanobacteria collection. After collecting the cyanobacteria, the staff tightens the limiting cover 15 and ensures the sealing of the shell 11 through the sealing ring 16 to prevent the sample from spilling during transportation, which further facilitates the staff's collection.

[0025] The limiting mechanism 2 includes inclined blocks 21 that are slidably connected to the inner walls of both sides of the housing 11. A cylinder 22 is fixedly connected to the outer side of each inclined block 21. A spring 23 is sleeved on the outer side of each cylinder 22. A limiting block 24 is fixedly connected to the outer side of each cylinder 22. A ring 25 is rotatably connected to the outer side of each limiting block 24. A limiting plate 26 is slidably connected to the lower end of each inclined block 21. A support column 27 is fixedly connected to the lower end of each limiting plate 26. A spring 28 is fixedly connected to the lower end of each support column 27. When the sealing cover 14 is opened, the support frame 18 is brought out, and the lake water enters the housing 11. The blue algae is blocked by the filter screen 19 and enters the interior of the support frame 18. The filter screen 19 effectively prevents the blue algae from leaking out of the housing 11, so that the blue algae can be collected in a concentrated manner for subsequent detection and analysis.

[0026] The auxiliary mechanism 3 includes a baffle 31 slidably connected to the bottom of the support frame 18, a rotating plate 32 rotatably connected to the bottom of the support frame 18, a protruding plate 33 fixedly connected to the bottom of the housing 11, and an auxiliary plate 34 fixedly connected to the bottom of the baffle 31. The baffle 31 is located inside the rotating plate 32. Through the operation of the rotating plate 32, the staff can quickly and easily remove the blue algae, further improving work efficiency and reducing the complexity of manual operation.

[0027] The implementation principle of a sampling device for detecting cyanobacteria in lakes according to this application embodiment is as follows: When it is necessary to collect cyanobacteria from a lake, the operator opens the limiting cover 15 by rotating the protruding plate at the upper end of the limiting cover 15. The operator can then hold the lifting ring 13 by hand or tie a rope to the lifting ring 13 and lower it into the lake to collect the cyanobacteria. When an appropriate amount has been collected, the cyanobacteria are pulled out by the lifting ring 13. Afterwards, the operator puts the limiting cover 15 back on the sealing cover 14 to seal the shell 11. The sealing ring 16 further ensures its airtightness and prevents the sample inside the shell 11 from spilling out during transportation. When it is necessary to detect cyanobacteria, the operator pulls the rings 25 on both sides of the shell 11. Then, the ring 25 will move outward along with the limiting block 24. The outward movement of the limiting block 24 will also move the cylinder 22. At this time, the spring 23 will be compressed and contract. Then, the cylinder 22 will also move outward along with the inclined block 21. At this time, the fixing block 17 loses its limiting position. When the inclined block 21 limits the fixing block 17, the bottom of the fixing block 17 will push the limiting plate 26 downward. The limiting plate 26 will push the support column 27 downward together. The spring 28 will be compressed and contract. When the inclined block 21 releases its limiting position on the fixing block 17, the spring 28 will extend again, thereby pushing the fixing block 17 upward, thus pushing the entire sealing cover 14 out a small distance. To facilitate the removal of the sealing cap 14 by staff, the support frame 18 is pulled out along with it. Lake water remains inside the housing 11, while cyanobacteria are trapped by the filter screen 19 and placed inside the support frame 18. When the sealing cap 14 is removed, the protruding plate 33 at the bottom of the housing 11 disengages from its restraint on the rotating plate 32. Staff then rotate the rotating plate 32 to release its restraint on the baffle 31. By pulling the auxiliary plate 34, staff can remove the baffle 31, which is located at the top of the baffle 31, allowing for the removal of the cyanobacteria. Staff can then separate the cyanobacteria from the water sample for testing, enabling timely identification of potential water quality problems. With appropriate management measures in place, after using the device, the staff will place the baffle 31 back into the bottom of the support frame 18 via the rotating plate 32. Then, the rotating plate 32 will be rotated to limit the baffle 31 and prevent it from falling off. After that, the sealing cover 14 will be put on, and the fixing block 17 will re-enter the interior of the housing 11. After the fixing block 17 contacts the inclined block 21, the inclined block 21 will move outward. When the fixing block 17 moves to the appropriate position, the inclined block 21 will limit the fixing block 17, thereby locking the sealing cover 14. At the same time, the bottom of the rotating plate 32 will also be in close contact with the auxiliary plate 34 to prevent the rotating plate 32 from rotating. The whole operation process is convenient and quick, further improving the work efficiency of the staff.
