Description

Technical Field

[0001] This utility model relates to the technical field of zooplankton detection and sampling devices, and in particular to a sampling device for detecting zooplankton in lakes. Background Technology

[0002] Plankton are a vital group in lake ecosystems, playing a crucial role in material cycling, energy flow, and ecological balance. As an important component of plankton, information on zooplankton, including its species composition, abundance distribution, and community structure, is significant for understanding the health, productivity, and environmental impacts of lake ecosystems.

[0003] However, most existing zooplankton sampling devices, when used in lakes, inevitably encounter problems where leaves or debris from the lake surface get into the mesh and clog the filter screen on the collection bottle. This necessitates operators removing the sampling device from the water to remove the leaves or debris from the filter screen, thus affecting sampling efficiency and increasing sampling time. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a sampling device for detecting zooplankton in lakes.

[0005] This utility model is achieved using the following technical solution: a sampling device for detecting zooplankton in lakes, comprising a fixed ring, an indicator on the top of the fixed ring, a filter screen fixedly connected to the inner wall of the fixed ring, a connecting block fixedly connected to the right side of the fixed ring, a connecting plate fixedly connected to the right side of the connecting block, a cleaning component at the bottom of the fixed ring, a connecting ring fixedly connected to the bottom of the fixed ring, a fixing hook snapped into the inner wall of the connecting ring, a mesh fixedly connected to the bottom of the fixing hook, a connecting sleeve fixedly connected to the bottom of the mesh, a collection bottle threadedly connected to the inner wall of the connecting sleeve, and an L-shaped fixing block fixedly connected to the bottom of the fixed ring;

[0006] The cleaning assembly includes a fixed frame, a waterproof shell fixedly connected to the top of the fixed frame, an electric push rod fixedly connected to the inner wall of the waterproof shell, a rotating disk fixedly connected to the output end of the electric push rod, a limit ring rotatably connected to the surface of the rotating disk, a protruding plate fixedly connected to the surface of the limit ring, a rack ring fixedly connected to the surface of the protruding plate, a gear one meshing with the inner wall of the rack ring, a rotating column one fixedly connected to the inner wall of the gear one, a gear two fixedly connected to the surface of the rotating column one, a chain meshing with the inner wall of the gear two, a gear three meshing with the end of the chain away from the gear two, a rotating column two fixedly connected to the inner wall of the gear three, and a rotary knob fixedly connected to the top of the rotating column two.

[0007] Through the above technical solution, rotating the rotary knob causes the second rotating column to drive the third gear to rotate, which in turn causes the second gear to rotate via the chain. The first rotating column also rotates, driving the first gear to rotate, which in turn causes the rack ring to drive the protruding plate to rotate. This causes the rotating disk to rotate on the inner wall of the limiting ring until the fixed block contacts the L-shaped fixed block. Then, the electric push rod is activated, causing its output end to drive the rotating disk upward. This causes the protruding column on the protruding plate to penetrate the holes in the filter screen, thereby pushing out leaves or debris from the filter screen. This prevents the filter screen from being clogged by leaves or debris, avoids the need for manual removal of leaves or debris from the filter screen, and thus reduces collection time and improves collection efficiency.

[0008] As a further improvement to the above solution, the bottom of the fixing ring is fixedly connected to the top of the fixing frame.

[0009] The above technical solution, by setting up a filter screen, prevents leaves or garbage from entering the collection bottle and thus affecting its collection effect.

[0010] As a further improvement to the above solution, the output end of the electric actuator extends through the top of the waterproof housing.

[0011] By using the above technical solution, and by setting up L-shaped fixing blocks and fixing blocks, the protruding column of the protruding plate can accurately pass through the holes in the filter screen when pushed by the electric push rod.

[0012] As a further improvement to the above solution, the surface of the rotating column is rotatably connected to the inner wall of the connecting plate.

[0013] As a further improvement to the above solution, one end of the rotating column 2 passes through the connecting plate and is rotatably connected to the inner wall of the connecting plate.

[0014] As a further improvement to the above solution, a fixing block is fixedly connected to the bottom of the protruding plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention features a cleaning assembly. Specifically, rotating a knob causes a rotating column two to drive a gear three to rotate. This gear two, via a chain, rotates, causing a rotating column one to rotate as well. This, in turn, drives the gear one to rotate, causing the rack ring to rotate the raised plate. Consequently, the rotating disk rotates within the limiting ring until the fixing block contacts the L-shaped fixing block. Then, an electric push rod is activated, causing its output end to move the rotating disk upwards. This allows the raised column on the raised plate to penetrate the holes in the filter screen, pushing out leaves or debris. This prevents the filter screen from becoming clogged by leaves or debris, eliminating the need for manual removal of leaves or debris from the filter screen, thus reducing collection time and improving collection efficiency.

[0026] Please combine Figure 1-5This embodiment of a sampling device for detecting zooplankton in lakes includes a fixed ring 1, an indicator 2 on the top of the fixed ring 1, a filter screen 3 fixedly connected to the inner wall of the fixed ring 1, a connecting block 4 fixedly connected to the right side of the fixed ring 1, a connecting plate 5 fixedly connected to the right side of the connecting block 4, a cleaning component 6 at the bottom of the fixed ring 1, a connecting ring 7 fixedly connected to the bottom of the fixed ring 1, a fixed hook 8 snapped into the inner wall of the connecting ring 7, a mesh 9 fixedly connected to the bottom of the fixed hook 8, a connecting sleeve 10 fixedly connected to the bottom of the mesh 9, a collection bottle 11 threadedly connected to the inner wall of the connecting sleeve 10, and an L-shaped fixing block 12 fixedly connected to the bottom of the fixed ring 1.

[0027] The cleaning component 6 includes a fixed frame 601, a waterproof shell 602 fixedly connected to the top of the fixed frame 601, an electric push rod 603 fixedly connected to the inner wall of the waterproof shell 602, a rotating disk 604 fixedly connected to the output end of the electric push rod 603, a limit ring 605 rotatably connected to the surface of the rotating disk 604, a protrusion plate 606 fixedly connected to the surface of the limit ring 605, a rack ring 607 fixedly connected to the surface of the protrusion plate 606, a gear 608 meshing with the inner wall of the rack ring 607, a rotating column 609 fixedly connected to the inner wall of the gear 608, a gear 610 fixedly connected to the surface of the rotating column 609, a chain 611 meshing with the inner wall of the gear 610, a gear 612 meshing with the end of the chain 611 away from the gear 610, a rotating column 613 fixedly connected to the inner wall of the gear 612, and a rotary knob 614 fixedly connected to the top of the rotating column 613.

[0028] The bottom of the retaining ring 1 is fixedly connected to the top of the retaining bracket 601.

[0029] The output end of the electric actuator 603 extends through the top of the waterproof housing 602.

[0030] The surface of the rotating column 609 is rotatably connected to the inner wall of the connecting plate 5.

[0031] One end of the rotating column 613 passes through the connecting plate 5 and is rotatably connected to the inner wall of the connecting plate 5.

[0032] The bottom of the raised plate 606 is fixedly connected to a fixing block 13.

[0033] The implementation principle of the sampling device for detecting zooplankton in a lake in this embodiment is as follows: In use, the fixed ring 1 is first vertically immersed in water according to the direction indicated by the indicator 2 on its surface, until the lake water submerges the indicator 2, thus allowing the mesh 9 and collection bottle 11 to also enter the water. Then, by shaking the connecting plate 5, the fixed ring 1, mesh 9, and collection bottle 11 are oscillated in the water via the connecting block 4, allowing zooplankton in the water to pass through the filter screen 3 into the mesh 9. Under the oscillation action, excess lake water enters the collection bottle 11, and zooplankton also enters the collection bottle 11 through the connecting sleeve 10. When leaves or debris in the lake clog the filter screen 3, simply turn the rotary knob 614, causing the rotating column 613 to drive the gear 612 to rotate, which in turn causes the gear 610 to rotate via the chain 611. The rotating column 609 also rotates, driving the gear 608 to rotate, causing the rack ring 607 to drive the protruding plate 606 to rotate. This causes the rotating disk 604 to rotate within the inner wall of the limiting ring 605 until the fixing block 13 contacts the L-shaped fixing block 12. Then, the electric push rod 603 is activated, causing its output end to drive the rotating disk 604 upward. This causes the protruding column on the protruding plate 606 to penetrate the holes in the filter screen 3, thereby pushing out leaves or debris from the filter screen 3. Then, the connecting plate 5 is rotated to change the direction of the fixing ring 1, thereby removing leaves or debris from the fixing ring 1. This prevents the filter screen from being clogged by leaves or debris, avoiding the need to manually remove the fixing ring 1 from the water and the leaves or debris from the filter screen, thus reducing collection time and improving collection efficiency. Then, the electric push rod 603 is activated again, causing its output end to drive the rotating disk 604 downward. This causes the protruding column on the protruding plate 606 to move out of the inner wall of the filter screen 3. Then, the rotary knob 614 is rotated in the opposite direction to the top, causing the protruding plate 606 to rotate in the opposite direction indicated by the indicator 2, thereby continuing collection.

[0034] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
