Description

Technical Field

[0001] The invention relates to the field of water body plankton collection, and in particular to a water body plankton collection, detection and filtering device. Background Art

[0002] Aquatic plankton refers to drifting organisms that live in water bodies, especially oceans, lakes and rivers, and lack the ability to move effectively. The collection and detection of aquatic plankton is an important means of marine environmental monitoring and marine ecological research. By selecting appropriate sampling methods and detection means, we can accurately and quickly obtain information on the types, quantities and distribution of plankton, providing a scientific basis for the protection and management of the marine environment.

[0003] Patent No. CN112774283B discloses a device for rapid on-site screening of plankton in seawater, including a screen box, a support plate arranged in the screen box, a collection box for collecting wastewater arranged at the bottom of the support plate, a flow hole for wastewater circulation is opened on the support plate, a filter barrel with a top hole is arranged on the support plate, and a filter assembly is also detachably mounted on the support plate, the filter assembly is arranged in at least two groups along the radial interval of the filter barrel, the filter assembly includes a bracket mounted on the support plate and a screen arranged on the bracket, the aperture of the screen of each filter assembly gradually decreases in a direction away from the filter barrel, the flow hole is opened between the filter assembly away from the filter barrel and the screen box, the screen of each group of filter assemblies can screen plankton of corresponding particle size, thereby obtaining plankton of corresponding particle size for research, and screening plankton of different particle sizes is performed separately at one time, thereby improving the screening rate and meeting the research needs.

The algae will clog the screen on the filter assembly, which requires manual cleaning at regular intervals, which is very inconvenient. Silt will be mixed in the water, affecting the detection effect when subsequently detecting plankton in the water. Summary of the invention

[0026] Beneficial effects of the present invention:

[0027] (1) Algae and impurities in the water flow will be intercepted by the filter plate on the top of the filter plate. Because the water flow is continuously filtered, the algae and impurities in the water flow will accumulate more and more on the filter plate. At this time, the driving component drives the rotating cleaning component to rotate, and the rotating cleaning component salvages and removes the algae and impurities on the filter plate.

[0028] (2) The water flows through the filter plate into the bottom of the working barrel and flows into the first filter barrel at the bottom of the working barrel. Because the water flow will carry a large amount of sediment and other substances, in order to avoid affecting the subsequent detection effect of plankton, the driving component drives the reciprocating component to block the sediment and separate the plankton mixed with the sediment. This setting is to prevent the sediment and plankton from mixing together and affecting the subsequent detection of plankton;

[0029] (3) The driven shaft rotates to drive the driving gear to rotate. The first driven gear is meshed with the driving gear, so the driven shaft rotates to drive the first support shaft to rotate. The first support shaft rotates to drive the cleaning disk on the top of the first support shaft to rotate. The driven shaft also rotates the filter plate, so that the cleaning disk cleans the filter plate. This setting is to prevent some substances from clogging the filter holes on the filter plate, resulting in the inability of water to pass through the filter plate smoothly and the inability to achieve the filtering and separation effect.

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] See also Figure 1-Figure 7 As shown, the present invention is a water body plankton collection, detection and filtering device, comprising a working barrel 1, a filter plate 11 and a first filter barrel 17; and also comprising a cleaning unit arranged on the working barrel 1;

[0041] The filter plate 11 is rotatably disposed in the working barrel 1;

[0042] The first filter barrel 17 is fixedly arranged at the bottom of the working barrel 1;

[0043] The cleaning unit is arranged on the working barrel 1, and includes a driving assembly, a rotating cleaning assembly and a reciprocating assembly; the driving assembly drives the rotating cleaning assembly to rotate; the driving assembly drives the reciprocating assembly to move;

[0044] The water flows into the working barrel 1, and the filter plate 11 in the working barrel 1 filters and separates the algae and impurities in the water flow. The water flow with plankton will pass through the filter plate 11 and enter the bottom of the working barrel 1. The algae and impurities in the water flow will be intercepted by the filter plate 11 at the top of the filter plate 11. Because the water flow is continuously filtered, the algae and impurities in the water flow will accumulate more and more on the filter plate 11. At this time, the driving component drives the rotating cleaning component to rotate, and the rotating cleaning component salvages and removes the algae and impurities on the filter plate 11. This setting is to continuously filter the top of the filter plate 11. Clean to avoid the continuous accumulation of algae and impurities that block the filter and prevent the water from passing through the filter plate 11 normally, affecting the subsequent filtering and separation work. The water flows through the filter plate 11 into the bottom of the working barrel 1 and flows into the first filter barrel 17 at the bottom of the working barrel 1. Because the water flow will carry a large amount of mud and other substances, avoid the subsequent impact on the detection effect of plankton. The reciprocating component is driven by the driving component to block the mud and separate the plankton mixed with the mud. This setting is to prevent the mud and plankton from mixing together and affecting the subsequent detection of plankton.

The waste plate 7 Holes are opened on the cleaning rod 10, which are arranged alternately with the cleaning rod 10. The working shaft 9 allows the cleaning rod 10 to overlap with the waste plate 7, and the algae and impurities on the cleaning rod 10 are intercepted through the holes on the waste plate 7, so that the algae and impurities on the cleaning rod 10 fall off to the waste plate 7, so that the cleaning rod 10 becomes clean, and then the algae and impurities on the filter plate 11 are continuously salvaged, and the operation is performed reciprocally to remove the algae and impurities on the filter plate 11, so as to prevent the algae and impurities from clogging the filter plate 11.

[0054] The driven shaft 30 rotates to drive the driving gear 29 fixed on the driven shaft 30 to rotate, and the driving gear 29 is meshed with the second driven gear 32, so when the driven shaft 30 rotates, the second support shaft 31 will also rotate accordingly, and the rotation of the second support shaft 31 drives the fixed rod 33 to make a circular motion, so that the driven block 34 brings the connecting column 35 to make reciprocating motion on the same axis, and the reciprocating motion of the connecting column 35 causes the stirring plate 36 fixed under the connecting column 35 to disturb the sediment, plankton and water flow entering the second filter barrel 38. This arrangement is to allow the stirring plate 36 to disturb the sediment, separate the plankton in the sediment from the sediment, and then discharge it into the first filter barrel 17 by the water flow, thereby avoiding the mixing of sediment and plankton during the subsequent detection of plankton, which affects the detection.

[0055] See also Figure 3 and Figure 5 As shown, the other end of the driven shaft 30 in the working barrel 1 is rotatably connected to the first support shaft 27; the middle of the first support shaft 27 is fixedly connected to the first driven gear 28; the top of the first support shaft 27 is fixedly connected to the cleaning plate 26; the first driven gear 28 is meshed with the driving gear 29; the top of the driven shaft 30 is fixedly connected to the filter plate 11; the cleaning plate 26 slides on the bottom of the filter plate 11;

[0056] The driven shaft 30 rotates to drive the driving gear 29 to rotate, and the first driven gear 28 is meshed with the driving gear 29, so the driven shaft 30 rotates to drive the first support shaft 27 to rotate, and the first support shaft 27 rotates to drive the cleaning disk 26 on the top of the first support shaft 27 to rotate. The rotation of the driven shaft 30 also drives the filter plate 11 to rotate, so that the cleaning disk 26 cleans the filter plate 11. This arrangement is to prevent some substances from clogging the filter holes on the filter plate 11, resulting in the inability of water to pass through the filter plate 11 smoothly, and the inability to achieve the filtering and separation effect.

[0058] The first bevel gear 12 is driven to rotate by the driving shaft 8, and the first bevel gear 12 is meshed with the second bevel gear 13, so the rotation of the first bevel gear 12 will drive the second bevel gear 13 to rotate, and the rotation of the second bevel gear 13 will rotate the connecting rod 14 and the first rotating wheel 22. The first rotating wheel 22 and the second rotating wheel 24 are sleeved with a belt 23, and the second rotating wheel 24 is rotated by the transmission of the belt 23. The rotation of the second rotating wheel 24 will rotate the connecting shaft 25 and the driven shaft 30, thereby starting the equipment in the working barrel 1 to operate. The shaft 16 and the limit plate 15 are used to limit the connecting rod 14 in the shaft 16 to prevent the connecting rod 14 from deviating from its position when it rotates.

[0059] See also Figure 1 and Figure 2 As shown, the side wall of the working barrel 1 is fixedly connected with a stacking groove 2 below the waste plate 7; and the baffle 3 is fixedly connected to the waste plate 7;

[0060] Algae and impurities enter the stacking trough 2 through the waste plate 7. When they are collected to a certain extent, they are uniformly processed by the staff. The baffle 3 on the waste plate 7 prevents the algae and impurities from slipping out of the waste plate 7 and scattering everywhere.

[0062] When the connecting column 35 is carried by the fixing rod 33 and the driven block 34 to perform reciprocating motion, in order to prevent the connecting column 35 from swinging randomly, the roller 41 on the connecting column 35 is allowed to slide in the limiting block 40, so that the connecting column 35 only performs reciprocating motion in the limiting block 40 without any random deviation.

[0063] See also Figure 1 , Figure 6 and Figure 7 As shown, the bottom of the second filter barrel 38 is fixedly connected to a drain pipe 19; the bottom of the drain pipe 19 is fixedly connected to a fixed frame 21; the fixed frame 21 is rotatably connected to a rotating rod 20; the bottom of the rotating rod 20 is fixedly connected to a piston 39; the piston 39 is slidably arranged in the drain pipe 19; the bottom of the first filter barrel 17 is fixedly connected to a discharge port 18;

[0064] When it is necessary to discharge the silt in the second filter barrel 38, the staff holds the handle at the bottom of the rotating rod 20 and rotates it. The rotating rod 20 is provided with a thread, and the thread on the rotating rod 20 cooperates with the fixed frame 21 to allow the rotating rod 20 to be raised and lowered and fixed. The staff rotates the rotating rod 20 to allow the piston 39 on the rotating rod 20 to move downward until it falls off the sewage pipe 19, allowing the silt to be released from the sewage pipe 19. The first filter barrel 17 is used to filter and separate the water flow, so that the plankton in the water flow is accumulated at the bottom of the first filter barrel 17. When testing is required, the staff releases the plankton at the bottom of the first filter barrel 17 through the discharge port 18 on the first filter barrel 17, and then sends it to a professional laboratory for testing.

[0065] See also Figure 2 and Figure 3 As shown, a limiting slide groove 37 is fixedly connected to the inner side wall of the working barrel 1; the filter plate 11 slides in the limiting slide groove 37;

[0066] The filter plate 11 is arranged in the shape of a groove, and then the filter plate 11 slides in the slide groove on the inner wall of the working barrel 1. This arrangement is to reduce the gap between the working barrel 1 and the filter plate 11, and prevent algae and impurities from entering the bottom of the working barrel 1 through the gap between the filter plate 11 and the working barrel 1.

[0067] The working principle of the present invention is as follows: water flows into the working barrel 1, and the filter plate 11 in the working barrel 1 filters and separates the algae and impurities in the water flow. The water flow with plankton will pass through the filter plate 11 and enter the bottom of the working barrel 1. The algae and impurities in the water flow will be intercepted by the filter plate 11 at the top of the filter plate 11. Because the water flow is continuously filtered, the algae and impurities in the water flow will accumulate more and more on the filter plate 11. At this time, the driving component drives the rotating cleaning component to rotate, and the rotating cleaning component salvages and removes the algae and impurities on the filter plate 11. This arrangement is to continuously filter the filter plate 1 1 is cleaned at the top to prevent the algae and impurities accumulated continuously from clogging the filter so that the water flow cannot pass through the filter plate 11 normally, affecting the subsequent filtering and separation work. The water flow through the filter plate 11 enters the bottom of the working barrel 1 and flows into the first filter barrel 17 at the bottom of the working barrel 1. Because the water flow will carry a large amount of sediment and other substances, it is avoided that the subsequent detection effect of plankton is affected. The reciprocating component is driven by the driving component to block the sediment and separate the plankton mixed with the sediment. This setting is to prevent the sediment and plankton from mixing together and affecting the subsequent detection of plankton.

[0068] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
