Description

A device for collecting planktonic algae Technical Field

[0001] This invention belongs to the field of phytoplankton collection technology, specifically a phytoplankton collection device. Background Technology

[0002] Phytoplankton collection devices are used to collect algae from rivers, lakes, and other bodies of water to observe the current algae population. There are many species of algae; some require sunlight and float on the surface, while others do not and remain submerged. Therefore, the collection device also collects underwater algae by placing the suction head underwater and then releasing the collected algae into a collection container. However, this method only collects underwater algae and cannot automatically collect and store algae at different depths. This results in algae from different depths being mixed together, making it impossible to observe the species and density of algae at different depths, thus compromising the rigor of subsequent experimental observations.

[0012] Preferably, a counterweight is fixedly installed at the bottom of the suction cylinder, a disc is fixedly installed at the top of the suction cylinder, and a circular tube is provided in the middle of the disc.

[0013] The beneficial effects of this invention are as follows:

[0014] 1. This invention uses a pump to deliver water drawn from the suction cylinder to the inner cavity of the first collection component. When the inner cavity of the collection component is filled with water, the collection component drives the conical pressure rod to descend, squeezing the moving plate and causing it to move. Then, through the meshing of the moving rack and transmission gear, the piston rod is driven to move towards the blocking chamber, thereby moving the three-stage contraction tube to the top of the interval collection chamber and compressing the air on the left side of the piston cylinder's inner cavity, discharging excess water into the inner cavity of the interval collection chamber. When the interval collection chamber descends, it drives the ratchet rack to rotate, thereby driving the threaded cylinder to rotate through the transmission component. The threaded cylinder then drives the blocking rod to move, so that the compressed air in the piston cylinder's inner cavity is injected into the inner cavity of the airbag through the air outlet telescopic hose, allowing the suction cylinder to obtain... Buoyancy moves the device upwards to the second depth. When the ratchet and ratchet gear 1 separate, the transmission assembly is driven by the coil spring rod to reset the blocking rod, thus blocking the air outlet telescopic hose. This fixes the suction cylinder at the second depth, allowing the pump to collect water from that depth. The intermediate collection chamber then drives the downward-pressing cone block to rotate the ratchet gear 3, causing the movable sleeve to move the three-stage contraction tube to the top of the second collection assembly. This achieves segmented collection of phytoplankton at different depths and automatically classifies and stores phytoplankton at different depths, preventing them from mixing together. This more accurately reflects the phytoplankton situation at different depths in the current water body, making subsequent observations and experiments more rigorous.

[0015] 2. In this invention, when the water in the first and second depth intervals is collected through the inner cavity of the interval collection chamber, the interval collection chamber moves downward, thereby driving the conical moving block to move towards the direction of the spring assembly three through the downward pressing conical block. Then, the ratchet rack two drives the ratchet gear two to rotate, and the ratchet gear two drives the rotating shaft of the inner cavity of the rotating cylinder to rotate, thereby contracting the pulling thread, thereby driving the rotating shaft of the inner cavity of the coil spring contraction cylinder to rotate. The coil spring contraction cylinder then drives the scraper to rotate, thereby scraping away the planktonic algae and impurities in the water remaining on the surface of the filter plate at the first depth. This realizes the cleaning of the filter plate in the interval between the first and second depths by moving the suction cylinder from the first depth, effectively avoiding the influence of the planktonic algae remaining on the surface of the filter plate at the previous depth on the collection of planktonic algae at the second depth.

[0016] 3. This invention works by filling the first collection component with water, representing the completion of algae collection at the first depth, thereby driving the three-stage contraction tube to the top of the interval collection chamber. At this time, the suction cylinder is floating, ensuring that the water collected during the suction cylinder's ascent is not discharged into the second collection component. When the suction cylinder floats to the second depth, the weight of the water in the interval collection chamber causes the downward-pressing conical block to press towards the conical moving block, which in turn moves the conical moving block, causing the ratchet rack three to drive the ratchet gear three to rotate. The rotation of the ratchet gear three then drives the threaded cylinder one to rotate, thereby moving the piston rod and causing the three-stage contraction tube to move above the second collection component. This allows the three-stage contraction tube to briefly pause between the two collection components after the water collection at the first depth is completed, thus discharging the algae collected during the ascent and ensuring that the algae collected during the suction cylinder's ascent does not affect the accuracy of the collection results.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 are within the scope of protection of the present invention.

[0027] As shown in Figures 1 to 8, this embodiment of the invention provides a planktonic algae collection device, including a float 1, a hull 2 ​​fixedly connected to the top of the float 1, a return spring 3 fixedly installed on the rear side of the hull 2, a moving rack 4 fixedly installed on the front side of the return spring 3, a moving plate 5 fixedly connected to the left side of the moving rack 4, a fixed spring assembly 6 fixedly installed on the rear side of the hull 2, a collection assembly 7 fixedly connected to the front side of the fixed spring assembly 6, a conical pressure rod 8 fixedly connected to the bottom end of the collection assembly 7, a piston cylinder 9 fixedly connected to the rear side of the hull 2, a threaded cylinder 10 movably connected to the right side of the piston cylinder 9, a drive anti-slip transmission belt 11 movably sleeved on the surface of the threaded cylinder 10, a transmission gear 12 being driven and connected to the threaded cylinder 10 via the drive anti-slip transmission belt 11, and a piston rod 13 movably sleeved inside the piston cylinder 9, with the piston rod 13 on the right side... A ball screw 14 is fixedly connected. An L-shaped rod 15 is fixedly connected to the left side of the piston rod 13. A movable sleeve rod 16 is fixedly connected to the top of the L-shaped rod 15. A spring assembly 18 is fixedly installed in the inner cavity of the hull 2. An interval collection chamber 19 is fixedly connected to the top of the spring assembly 18. A spring assembly 20 is fixedly connected to the left side of the interval collection chamber 19. A ratchet rack 21 is fixedly connected to the left side of the spring assembly 20. A ratchet gear 22 meshes with the surface of the ratchet rack 21. A transmission assembly 23 is provided on the rear side of the ratchet gear 22. A blocking chamber 24 is fixedly installed at the bottom of the piston cylinder 9. A blocking rod 25 is movably sleeved in the inner cavity of the blocking chamber 24. A threaded cylinder 26 is movably connected to the rear side of the blocking chamber 24. A ball screw 27 is fixedly connected to the rear side of the blocking rod 25. An air outlet telescopic hose 29 is fixedly connected to the bottom of the blocking chamber 24.

[0028] The working principle and beneficial effects of the above technical solution are as follows: The extraction pump 31 delivers the water extracted from the suction cylinder 34 to the inner cavity of the first collection component 7. When the inner cavity of the collection component 7 is filled with water, it drives the conical pressure rod 8 to descend and squeeze the moving plate 5, causing the moving plate 5 to move. Then, through the meshing of the moving rack 4 and the transmission gear 12, it drives the piston rod 13 to move towards the blocking chamber 24, thereby driving the three-stage contraction tube 32 to move to the top of the interval collection chamber 19 and compressing the air on the left side of the inner cavity of the piston cylinder 9, discharging the excess water into the inner cavity of the interval collection chamber 19. When the interval collection chamber 19 descends, it drives the ratchet rack 21 to drive the ratchet gear 22 to rotate, thereby driving the threaded cylinder 26 to rotate through the transmission component 23. Then, through the threaded cylinder 26, it drives the blocking rod 25 to move, thereby allowing the compressed air in the inner cavity of the piston cylinder 9 to be injected into the airbag through the air outlet telescopic hose 29. The inner cavity of 30 allows the suction cylinder 34 to gain buoyancy and move upward to the second depth. When the ratchet 21 separates from the ratchet gear 22, the transmission component 23 is driven by the coil spring rod 28 to reset the blocking rod 25, thereby blocking the air outlet telescopic hose 29. This fixes the suction cylinder 34 at the second depth to collect water from the second depth. Then, the interval collection chamber 19 drives the downward pressing cone block 40 to move downward, driving the ratchet gear 49 to rotate. This causes the movable sleeve rod 16 to move the three-stage contraction tube 32 to the top of the second collection component 7. This achieves segmented collection of phytoplankton at different depths in the water body and automatically classifies and stores phytoplankton at different depths to prevent them from mixing together. This more accurately reflects the phytoplankton situation at different depths in the current water body, making subsequent observations and experiments more rigorous.

[0029] As shown in Figure 7, in one embodiment, an airbag 30 is fixedly connected to the bottom end of the air outlet telescopic hose 29, an extraction pump 31 is fixedly connected to the top end of the hull 2, a three-stage contraction tube 32 is threadedly connected to the output end of the extraction pump 31, a telescopic extraction hose 33 is fixedly connected to the output end of the extraction pump 31, and a suction cylinder 34 is fixedly connected to the bottom end of the telescopic extraction hose 33.

[0030] The working principle and beneficial effects of the above technical solution are as follows: the extraction pump 31 is started and the phytoplankton and water in the water are collected through the suction cylinder 34. The three-stage shrink tube 32 is then connected to the output end of the extraction pump 31, so that the three-stage shrink tube 32 can be disassembled, so that people will not be blocked by the three-stage shrink tube 32 when they take the collection component 7.

[0031] As shown in Figure 4, in one embodiment, a spring assembly 37 is fixedly connected to the front side of the inner cavity of the hull 2, a moving rod 38 is fixedly connected to the rear side of the spring assembly 37, a conical moving block 39 is fixedly connected to the rear side of the moving rod 38, a pressing conical block 40 is fixedly connected to the right side of the interval collection chamber 19, a spring assembly 41 is fixedly connected to the top of the conical moving block 39, a ratchet rack 42 is fixedly connected to the top of the spring assembly 41, a rotating cylinder 43 is fixedly connected to the right side of the inner cavity of the hull 2, a ratchet gear 44 is provided on the rotating shaft of the rotating cylinder 43, a pulling wire 45 is sleeved in the inner cavity of the ratchet gear 44, a filter plate 36 is fixedly connected to the right side of the suction cylinder 34, a coil spring shrink cylinder 46 is fixedly connected to the inner cavity of the suction cylinder 34, and a scraper 47 is provided on the rotating shaft of the coil spring shrink cylinder 46.

[0032] The working principle and beneficial effects of the above technical solution are as follows: When the inner cavity of the interval collection chamber 19 begins to collect water in the first and second depth intervals, the interval collection chamber 19 moves downward, thereby driving the conical moving block 39 to move towards the spring assembly 37 through the downward pressing conical block 40. Then, the ratchet rack 2 42 drives the ratchet gear 2 44 to rotate, and the ratchet gear 2 44 drives the rotating shaft of the inner cavity of the rotating cylinder 43 to rotate, thereby contracting the pulling thread 45, thereby driving the rotating shaft of the inner cavity of the coil spring contraction cylinder 46 to rotate. The coil spring contraction cylinder 46 then drives the scraper 47 to rotate, thereby scraping away the planktonic algae and impurities in the water remaining on the surface of the filter plate 36 at the first depth. This achieves the cleaning of the filter plate 36 by the suction cylinder 34 moving from the first depth interval to the second depth interval, effectively avoiding the impact of the planktonic algae remaining on the surface of the filter plate 36 at the previous depth on the collection of planktonic algae at the second depth.

[0033] As shown in Figure 2, in one embodiment, a ratchet rack 348 is provided at the top of the moving rod 38, and a ratchet gear 349 is fixedly installed on the surface of the threaded cylinder 10.

[0034] The working principle and beneficial effects of the above technical solution are as follows: When the water in the inner cavity of the first collection component 7 is full, the phytoplankton at the first depth has been collected, thereby driving the three-stage contraction tube 32 to move to the top of the interval collection chamber 19. At this time, the suction cylinder 34 is floating, so that the water collected during the floating process of the suction cylinder 34 will not be discharged into the second collection component 7. When the suction cylinder 34 floats to the second depth, the weight of the water in the inner cavity of the interval collection chamber 19 drives the downward cone block 40 to press in the direction of the cone moving block 39, thereby driving... The movement of the conical moving block 39 causes the ratchet rack 3 48 to drive the ratchet gear 3 49 to rotate. The rotation of the ratchet gear 3 49 then drives the threaded cylinder 10 to rotate, thereby moving the piston rod 13. This causes the three-stage contraction tube 32 to move above the second collection component 7. This allows the three-stage contraction tube 32 to pause briefly between the two collection components 7 after the water collection at the first depth is completed, thus discharging the planktonic algae collected during the ascent. This ensures that the planktonic algae in the suction tube 34 during the ascent will not affect the accuracy of the collection results.

[0035] As shown in Figure 4, in one embodiment, two support C-shaped plates 17 are provided on the front side of the inner cavity of the hull 2. The inner cavities of the two support C-shaped plates 17 are respectively movably sleeved with a movable rack 4 and a movable rod 38. The transmission gear 12 meshes with the movable rack 4, the threaded cylinder 26 meshes with the ball screw 27, the ball screw 14 meshes in the inner cavity of the threaded cylinder 10, the front side of the blocking rod 25 is fixedly connected with an elliptical rod, and a weight block is fixedly installed on the front side of the hull 2.

[0036] The working principle and beneficial effects of the above technical solution are as follows: the moving rod 38 and the moving rack 4 are supported by two supporting C-shaped plates 17 respectively, thereby improving the stability of the moving rod 38 and the moving rack 4. The elliptical rod on the front side of the blocking rod 25 is used to position and guide the blocking rod 25, thereby preventing the blocking rod 25 from rotating and not moving. The weight block on the front side of the hull 2 ​​ensures that the weight on the front and rear sides of the float 1 is the same.

[0037] As shown in Figure 5, in one embodiment, a collection bucket is movably fitted inside the collection component 7, and the movable plate 5 is composed of three conical blocks, which are respectively located at the bottom ends of three conical pressure rods 8.

[0038] The working principle and beneficial effects of the above technical solution are as follows: After the collection is completed, the staff pulls the collection bucket out of the inner cavity of the collection component 7 to process the collected planktonic algae. Then, through the three conical blocks of the moving plate 5, the three collection components 7 fall in turn, which can drive the moving plate 5 to move.

[0039] As shown in Figure 4, in one embodiment, the fixed spring assembly 6, spring assembly 18, spring assembly 20, spring assembly 37 and spring assembly 41 are all composed of springs and damping telescopic rods. The bottom end of the interval collection chamber 19 is provided with a slow water outlet pipe, and the rear side of the hull 2 ​​is provided with a water outlet.

[0040] The working principle and beneficial effects of the above technical solution are as follows: the spring of the fixed spring assembly 6 pulls the collection assembly 7 to fix the collection assembly 7 and make it stable. Then, the damping telescopic rod prevents the collection assembly 7 from displacing. The spring assembly 18 makes the water in the cavity of the interval collection chamber 19 reset after being drained from the slow outlet pipe. The spring assembly 20 makes the ratchet rack 21 not affect the rotation of the ratchet gear 22 during the rising process. The spring assembly 37 makes the ratchet gear 244 separate from the ratchet rack 242 and the water in the cavity of the interval collection chamber 19 drained. The spring assembly 37 drives the conical moving block 39 to reset. The spring assembly 41 makes the ratchet rack 242 reset so as not to affect the rotation of the ratchet gear 244. Finally, the water discharged from the interval collection chamber 19 can be discharged through the outlet on the rear side of the hull 2.

[0041] As shown in Figure 6, in one embodiment, a spring rod 28 is provided in the middle of the transmission assembly 23. The transmission assembly 23 is composed of two anti-slip transmission belts sleeved on the surface of the spring rod 28. The blocking chamber 24 is connected to the inner cavity of the airbag 30 through the air outlet telescopic hose 29.

[0042] The working principle and beneficial effects of the above technical solution are as follows: During the descent of the ratchet rack 21, it drives the ratchet gear 22 to rotate, thereby driving the threaded cylinder 26 to rotate through the transmission assembly 23 and the spring rod 28. This causes the air in the inner cavity of the piston cylinder 9 to be injected into the inner cavity of the airbag 30 through the air outlet telescopic hose 29. When the ratchet rack 21 descends to a certain distance, the ratchet rack 21 separates from the ratchet gear 22. At this time, the force of the spring rod 28 drives the threaded cylinder 26 to reverse, thereby driving the blocking rod 25 to move and reset, and re-blocking the air outlet telescopic hose 29, so that the position of the suction cylinder 34 no longer rises.

[0043] As shown in Figure 7, in one embodiment, a counterweight 35 is fixedly installed at the bottom end of the suction cylinder 34, and a disc is fixedly installed at the top end of the suction cylinder 34, with a circular tube provided in the middle of the disc;

[0044] The working principle and beneficial effects of the above technical solution are as follows: The counterweight 35 at the bottom of the suction cylinder 34 allows the suction cylinder 34 to move to the bottom when it is placed in water, and the buoyancy generated when the air bladder 30 is inflated can balance the counterweight 35, thereby changing the depth of the suction cylinder 34 in the water. The air bladder 30 is installed on the disc at the top of the suction cylinder 34, and the air bladder 30 is blocked by the round tube in the middle of the disc, thereby preventing the air bladder 30 from squeezing the telescopic extraction hose 33 when it is inflated, thus reducing the water flow in the telescopic extraction hose 33.

[0045] Working principle and usage process: The float plate 1 is placed on the water surface. At this time, the suction cylinder 34 falls to the deepest position under the weight of the counterweight block 35. Then, the pump 31 extracts water at this depth and discharges it into the inner cavity of the first collection component 7. When the inner cavity of the first collection component 7 begins to be filled with water, it drives the first collection component 7 to descend. Then, the conical pressure rod 8 squeezes the moving plate 5, causing the moving plate 5 to move. The movement of the moving plate 5 drives the moving rack 4 to move, which in turn drives the transmission gear 12 to rotate. This drives the anti-slip transmission belt 11 to rotate the threaded cylinder 10. The rotation of the threaded cylinder 10 drives the ball screw 14 that meshes with it to rotate, thereby causing the piston rod 13 to move towards the blockage chamber 24 and compress the air, thereby driving the movable sleeve rod 16 to move. The movable sleeve rod 16 drives the telescopic extraction hose 33 to move above the first collection component 7. When the first collection component... When the water in the inner cavity of chamber 7 is full, the telescopic extraction hose 33 moves between the two collection components 7 and discharges the water into the inner cavity of the interval collection chamber 19. At this time, the interval collection chamber 19 begins to descend, which in turn drives the ratchet rack 21 to descend. Through the meshing of the ratchet rack 21 and the ratchet gear 22, the ratchet gear 22 is driven to rotate. Then, through the transmission component 23, the threaded cylinder 26 is driven to rotate, thereby driving the ball screw 27 to rotate. When the ball screw 27 rotates, it drives the blocking rod 25 to move to the front side of the blocking rod 25, thereby making the inner cavity of the piston cylinder 9 connected with the air outlet telescopic hose 29. The compressed air in the inner cavity of the piston cylinder 9 is injected into the inner cavity of the airbag 30 through the air outlet telescopic hose 29. When the water in the inner cavity of the interval collection chamber 19 reaches one-quarter, the ratchet rack 21 and the ratchet gear 22 separate. Then, through the elasticity of the coil spring rod 28, the threaded cylinder 26 is reversed, thereby driving the blocking rod 25 to reset and re-block the air outlet telescopic hose 29.

[0046] When the suction cylinder 34 moves to the second depth, the water in the inner cavity of the interval collection chamber 19 causes the downward cone block 40 to descend, thereby pushing the cone moving block 39 to move. The movement of the cone moving block 39 causes the ratchet rack 3 48 to move, thereby causing the ratchet gear 3 49 to rotate, causing the ball screw 14 to rotate again, thereby starting to drive the piston rod 13 to move. Then, the movement of the piston rod 13 causes the telescopic extraction hose 33 to move above the second collection component 7, discharging the water at the second depth into the second collection component 7. This process is repeated to inject the water at the water meter into the inner cavity of the third collection component 7.

[0047] Water in the inner cavity of the interval collection chamber 19 is discharged into the inner cavity of the hull 2 ​​through the slow water outlet pipe, and then discharged through the water outlet of the hull 2. When the water in the inner cavity of the interval collection chamber 19 is drained, the ratchet gear 22 will not rotate due to the elasticity of the ratchet rack 21 and the spring assembly 20.

[0048] When water begins to be injected into the collection chamber 19, the downward pressing cone block 40 squeezes the cone moving block 39, thereby moving the moving rod 38. The movement of the moving rod 38 drives the ratchet rack 42 to move, thereby driving the ratchet gear 44 to rotate. This, in turn, drives the rotating shaft of the inner cavity of the rotating cylinder 43 to drive the pulling thread 45 to contract, thereby driving the rotating shaft of the inner cavity of the coil spring contraction cylinder 46 to rotate, thereby driving the scraper 47 to scrape the surface of the filter plate 36. When the suction cylinder 34 rises, the counterweight block 35 remains taut due to the contraction force of the coil spring contraction cylinder 46.
