[0002] Common sieves on the market are similar to steamers, with a large diameter of about 15 cm or more and a shallow depth of about 4.5 cm. They are usually used alone. However, in actual work, if you want to separate and collect phytoplankton of various particle sizes in lake water at one time, you need to stack these sieves with different apertures. However, these sieves do not fit well together and are easy to fall apart, often requiring manpower to fix the relative positions of the sieves.

[0003] Existing Chinese patent CN218421262U discloses a sieve cylinder for collecting plankton in water bodies. The sieve cylinder for collecting plankton in water bodies connects multiple sieve cylinders together by opening corresponding threads. The sieve holes on the sieve cylinders gradually decrease from top to bottom, thereby realizing the separate collection of plankton of different particle sizes.

[0004] However, when a plurality of screen drums are connected by threaded connection, the screen drums need to be rotated one by one, which takes a long time to install, and the screen drums also need to be rotated one by one when disassembling, which also takes a long time to disassemble.

[0021] 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 the embodiments.

[0022] See also Figure 1-Figure 4 The utility model provides a technical solution: a sieve drum for collecting plankton in a water body, comprising a sieve drum 1, a sieve drum 2, and a sieve drum 3, wherein the inner walls of the sieve drum 1, the sieve drum 2, and the sieve drum 3 are all fixedly mounted with a sieve plate 4, the sieve drum 1, the sieve drum 2, and the sieve drum 3 are stacked together from top to bottom, and the outer walls of the sieve drum 1, the sieve drum 2, and the sieve drum 3 are fixedly mounted with a mounting mechanism 5;

[0023] The mounting mechanism 5 includes a hollow shell 501. The hollow shell 501 is provided with three groups and is respectively mounted on the outer walls of the sieve drum 1, the sieve drum 2, and the sieve drum 3. An L-shaped block 503 is fixedly mounted on the inner wall of the back side of the hollow shell 501. The L-shaped block 503 is close to the bottom end of the hollow shell 501. A slide rod 507 is fixedly mounted on the inner wall of the hollow shell 501. A connecting plate 502 is provided on the sliding sleeve of the outer wall of the slide rod 507. A spring 508 is fixedly mounted on the back side of the connecting plate 502. The rear end of the spring 508 is fixedly connected to the inner wall of the back side of the hollow shell 501. A threaded pressure rod 504 is threadedly connected to the front side of the hollow shell 501. The rear end of the threaded pressure rod 504 is pressed on the connecting plate 502, and a card slot 505 is provided on the front of the bottom end of the L-shaped block 503. A card block 506 is fixedly installed on the back of the connecting plate 502, and the card block 506 is opposite to the card slot 505, and the outer diameter of the card block 506 is consistent with the inner diameter of the card slot 505. A card seat 5010 is fixedly installed on the top of the connecting plate 502, and a card plate 509 is fixedly installed on the bottom end of the connecting plate 502, and the card plate 509 is opposite to the card seat 5010, and the outer diameter of the card plate 509 is consistent with the inner diameter of the card seat 5010. The floating Swimming organisms are classified and collected, and the installation mechanism 5 is used to connect the screen drum 1 1, the screen drum 2 2, the screen drum 2 2, and the screen drum 3 3. When connecting, it is only necessary to align the screen drum 1 1, the screen drum 2 2, and the screen drum 3 3 and stack them together. At this time, the upper clamping plate 509 is inserted into the lower clamping seat 5010, and the upper L-shaped block 503 is extended into the lower hollow shell 501. Then, a threaded pressure rod 504 is rotated to make the threaded pressure rod 504 move, thereby pushing the connecting plate 502 to move backward. The movement of the connecting plate 502 drives the clamping plate 509 and the clamping seat 5010 on it to move, thereby moving the upper and lower connecting plates 502 forward synchronously. The movement of the connecting plate 502 drives the block 506 to move until the block 506 is stuck in the slot 505, and the fixation of the screen drum 1 1, the screen drum 2 2, and the screen drum 3 3 can be completed. The connection is simple. When disassembling, it is only necessary to reversely rotate the threaded pressure rod 504 to move the threaded pressure rod 504 forward. At this time, the spring 508 pushes the connecting plate 502 to move, so that the block 506 is disengaged from the slot 505, and the screen drum 1 1, the screen drum 2 2, and the screen drum 3 3 can be separated. The operation is simple and quick. After the screen drum 1 1, the screen drum 2 2, and the screen drum 3 3 are stacked together, it is only necessary to rotate one or two threaded pressure rods 504.

[0024] There is a gap between the left and right outer walls of the connecting plate 502 and the inner wall of the hollow shell 501 to prevent the connecting plate 502 from rubbing against the inner wall of the hollow shell 501 during movement. Two sliding rods 507 are provided with a sliding connection to the connecting plate 502 to limit the connecting plate 502 and prevent it from rotating.

[0025] The height of the hollow shell 501 is consistent with the height of the sieve drum 1, sieve drum 2, and sieve drum 3. The top of the hollow shell 501 is higher than the top of the corresponding sieve drum, so that when the individual sieve drums 1, 2, and 3 are placed on the ground, the structure on the mounting mechanism 5 will not contact the ground, ensuring that the sieve drums 1, 2, and 3 are placed stably.

[0026] The apertures of the sieve plates 4 in the sieve drum 1, sieve drum 2, and sieve drum 3 decrease in sequence, and the plankton is screened in layers;

[0027] The bottom ends of the sieve drum 1, sieve drum 2, sieve drum 3 are provided with retracted skirts, and the top inner walls of the sieve drum 1, sieve drum 2, sieve drum 3 are provided with grooves corresponding to the skirts, so that when the sieve drum 1, sieve drum 2, sieve drum 3 are stacked together, the skirts at the bottoms of the sieve drum 1, sieve drum 2, 2 can just be stuck in the corresponding grooves, making the connection of the sieve drum 1, sieve drum 2, sieve drum 3 more stable, and the inner walls of the grooves are fixedly installed with elastic compression rings 6, which utilize the elastic contraction characteristics of the elastic compression rings 6 to compress the skirts, that is, after the sieve drum 1, sieve drum 2, sieve drum 3 are stacked together, the sieve drum 1, sieve drum 2, sieve drum 3 are not easy to shake;

[0028] The tops of the sieve drum 1 1 , sieve drum 2 2 and sieve drum 3 are all provided with diversion ports 7 to facilitate the flow of water into the sieve drum 1 1 , sieve drum 2 2 and sieve drum 3 3 . A turning handle is fixedly installed on the front of the threaded pressure rod 504 , making it easier to rotate the threaded pressure rod 504 .

[0029] Working principle: When in use, stack the screen drum 1, screen drum 2, and screen drum 3 together, then at this time, the upper clamping plate 509 is inserted into the lower clamping seat 5010, and a threaded pressure rod 504 is rotated to move the threaded pressure rod 504, thereby pushing the connecting plate 502 to move backward, and the movement of the connecting plate 502 drives the clamping plate 509 and the clamping seat 5010 thereon to move, and then moves the upper and lower connecting plates 502 forward synchronously, and the movement of the connecting plate 502 drives the clamping block 506 to move until the clamping block 506 is clamped into the clamping slot 505, the sieve drum 1 1, sieve drum 2 2, and sieve drum 3 can be fixed. The connection is simple. When disassembling, you only need to rotate the threaded pressure rod 504 in the opposite direction to move the threaded pressure rod 504 forward. At this time, the spring 508 pushes the connecting plate 502 to move, so that the block 506 is disengaged from the card slot 505, and the sieve drum 1 1, sieve drum 2 2, and sieve drum 3 can be separated. The operation is simple and quick. After stacking the sieve drum 1 1, sieve drum 2 2, and sieve drum 3 together, you only need to rotate one or two threaded pressure rods 504.

[0030] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.
