Description

Technical Field

[0001] The present invention relates to the technical field of plankton density detection, and in particular to a plankton density monitoring device for marine disaster warning. Background Art

[0002] Marine plankton is an extremely important component of the marine ecosystem. It has a wide variety of species and diverse functions. The vast majority of plankton are the basis of the marine food chain and make positive contributions to the ecosystem. However, excessive density of marine plankton (such as algal blooms or red tides) can cause multiple hazards to the marine ecosystem and human activities.

[0003] Currently, when testing the density of marine plankton, samples are usually taken from different areas of the same water area, and then the marine plankton density of this water area is comprehensively evaluated based on the sampling results of each area. However, in the marine environment, fish predation and the ebb and flow of tides can easily lead to large differences in the density of marine plankton in different areas of the same water area. After the life cycle of plankton ends, the debris or shells will gradually sink to the seabed. A large amount of plankton debris is decomposed by heterotrophic bacteria in the bottom mud, consuming oxygen and forming an anoxic environment. Under anoxic conditions, sulfate-reducing bacteria decompose organic matter into hydrogen sulfide, poisoning benthic organisms and affecting the ecological environment of the ocean bottom. Therefore, sampling of plankton sediment debris is also to explore the marine disasters caused by the large-scale deposition of plankton debris. Therefore, a marine disaster warning plankton density monitoring device is proposed. Summary of the Invention

[0022] Example, see Figures 1 to 12 A marine disaster warning plankton density monitoring device includes an anchoring ladder column 1 and a plurality of positioning suspension seats 2. The top of the anchoring ladder column 1 is connected to a capping seat 4 through a lifting umbrella column 3. The capping seat 4 is connected to the positioning suspension seat 2 through a plurality of umbrella support assemblies. Furthermore, a plurality of anchoring rods are fixedly connected to the bottom end of the anchoring ladder column 1, and a plurality of V-shaped diverter plates 8 are fixedly connected to the front and rear side walls of the anchoring ladder column 1. The plurality of V-shaped diverter plates 8 are arranged in a stepped manner from top to bottom. The umbrella support assembly consists of a two-way push column 6 and an oblique support column 7. The outer side wall of the lifting umbrella column 3 is slidably connected to an electric control guide ring 5. The outer side wall of the electric control guide ring 5 is rotatably connected to one end of the plurality of two-way push columns 6 through a plurality of control rotating seats. The other end of the two-way push column 6 is slidably connected to the oblique support column 7 through a sliding seat. The two ends of the oblique support column 7 are rotatably connected to the capping seat 4 and the positioning suspension seat 2 through two control rotating seats respectively. It should be noted that: the anchoring ladder column 1 is transported to the water area to be monitored, and then the anchoring ladder column 1 is lifted by a lifting machine, so that the V-shaped diverter plate 8 on one side of the anchoring ladder column 1 is installed in the water area to be measured facing the shore. The lifting operation at sea is an existing technical means and will not be described in detail here. Then, according to the area of ​​the water area to be measured, the electric control guide ring 5 is controlled to move on the lifting umbrella column 3, and one end of the two-way push column 6 moves up with the electric control guide ring 5, and the other end of the two-way push column 6 will push the oblique support column 7 obliquely, so that the multiple oblique support columns 7 are synchronously expanded outward, so that the multiple positioning suspension seats 2 are expanded outward, and the positioning suspension seat 2 maintains a relatively horizontal state by adjusting the rotation with the oblique support column 7, thereby changing the range of waters that can be monitored by the entire equipment; The above-mentioned advantages are as follows: by utilizing the change of the umbrella-shaped structure of the plurality of oblique supports 7, the area of ​​the area where the plurality of oblique supports 7 are deployed can also be changed accordingly, thereby adjusting the range required to be monitored in different waters and at different times, making the monitoring operation flexible and convenient.

[0023] The left and right side walls of the anchoring ladder column 1 are connected to the tensioning bottom platform 9 and the adjusting top platform 12. The adjusting top platform 12 and the bottom end of the positioning suspension seat 2 are connected to two auxiliary sampling tubes 22 through a steel cable 10. A two-way threaded column 14 is provided between the two auxiliary sampling tubes 22. A reciprocating assembly for monitoring plankton at different depths is provided on the outer wall of the two-way threaded column 14. The main sampling tube 20 is symmetrically provided above and below the reciprocating assembly. An opening and closing assembly for controlling the start of sampling is provided between the main sampling tube 20 and the auxiliary sampling tube 22; Furthermore, the top of the tensioning bottom platform 9 is rotatably connected to the tensioning shaft through the mounting plate, and the outer side walls of both ends of the tensioning shaft are sleeved with torsion springs 11, and the outer side wall of the tensioning shaft is wound with a steel cable 10. The top of the adjusting top platform 12 is fixedly connected to the adjusting motor 13 through the mounting plate, and the steel cable 10 located above is wound on the output shaft of the adjusting motor 13. The reciprocating assembly consists of a reciprocating frame 15 and a knob 16. The inner side wall of the reciprocating frame 15 is fixedly connected to the knob 16, and the knob 16 is slidably connected to the inner side wall of the bidirectional threaded groove on the bidirectional threaded column 14. A plurality of imaging plankton recorders 17 are fixedly connected to the outer side wall of the reciprocating frame 15, and the top and bottom ends of the reciprocating frame 15 are fixedly connected to impact wheels 18. The ends of the two impact wheels 18 are fixedly connected to a trigger magnetic ring 19. The auxiliary sampling cylinder 22 located above is fixedly connected to the bottom end of the upper steel cable 10, and the auxiliary sampling cylinder 22 located below is fixedly connected to the top end of the lower steel cable 10. The main sampling cylinder 20 is connected to the auxiliary sampling cylinder 22 through two guide tubes 21. The opening and closing assembly consists of a closing spring 23 and two open magnetic half rings 26. The inner end surface of the auxiliary sampling cylinder 22 is connected to an adjusting piston column 24 through the closing spring 23. The adjusting piston column 24 is fixedly connected to two sealing arc plates 25 that adapt to the opening of the main sampling cylinder 20. The sealing arc plates 25 are fixedly connected to the open magnetic half rings 26 through a fixing rod. The end of the main sampling cylinder 20 is made of magnet material. It should be noted that: during monitoring, the adjusting motors 13 on the adjusting top platforms 12 on the left and right sides of the anchor ladder column 1 adjust the height of the two-way threaded column 14 between the tensioning bottom platform 9 and the adjusting top platform 12 by winding and loosening the steel cable 10, and adjust the monitoring water depth according to the sea water conditions. When there is a tide at sea, the water flow is blocked by the V-shaped diverter plate 8 into two diverter flows on both sides, reducing the impact of the water flow on the anchor ladder column 1. The separated side water flow will impact the two impact wheels 18 above and below the reciprocating frame 15, so that the reciprocating frame As the impact wheel 18 rotates on the bidirectional threaded column 14, the knob 16 slides in the bidirectional threaded groove on the bidirectional threaded column 14, causing the reciprocating frame 15 to perform an up and down reciprocating motion on the bidirectional threaded column 14, thereby driving multiple imaging plankton recorders 17 to rotate synchronously up and down to shoot sinking particles and plankton in real time, and automatically classify and count them in combination with AI recognition. When the reciprocating frame 15 first moves to the end, the trigger magnetic ring 19 will approach the open magnetic half ring 26 and produce an electric shock to the open magnetic half ring 26. The magnetic repulsion force is generated, causing the open magnetic half ring 26 to move under the action of the magnetic repulsion force, thereby driving the sealing arc plate 25 and the regulating piston column 24 to move together. The movement of the sealing arc plate 25 will open the sealed space of the main sampling cylinder 20, allowing the water sample of the upper plankton to enter and enter the auxiliary sampling cylinder 22 through the guide tube 21. As the water sample continues to enter, the water sample in the auxiliary sampling cylinder 22 cooperates with the closing spring 23 to squeeze the regulating piston column 24 synchronously, and gradually squeeze the regulating piston column 24 to make the sealing arc plate 25 close again. At this time The main sampling tube 20 and the auxiliary sampling tube 22 are full of water samples. The open magnetic half ring 26 is subsequently squeezed by the magnetic repulsion force and cannot push the sealing arc plate 25 to open again, avoiding affecting the initial plankton water sample in the subsequent process. In the state of static flow or small water flow, the impact wheel 18 is subjected to a small impact force, and it is difficult to drive the reciprocating sleeve 15 to rotate on the bidirectional threaded column 14, avoiding opening the main sampling tube 20 for sampling in the static flow state. The bidirectional threaded columns 14 below each positioning suspension seat 2 maintain a synchronous monitoring and sampling state. The benefits based on the above are: in this way, the up and down reciprocating motion of the reciprocating frame 15 on the bidirectional threaded column 14 can be used to monitor the plankton density at different depths under tidal conditions, and in the initial stage of monitoring, sealed sampling of shallow and deep plankton water samples can be performed, so that the detection of plankton density has high accuracy while ensuring real-time visualization.

[0024] The end of the steel cable 10 located below the positioning suspension seat 2 is connected to a sediment sampling barrel 27, the bottom end of the sediment sampling barrel 27 is connected to a notched sleeve 29, the notched sleeve 29 is connected to an anchoring protrusion 31 through multiple bursting discs 30, and a rotary assembly for sampling sediment plankton is provided in the notched sleeve 29; Furthermore, the bottom end of the positioning suspension seat 2 is wound with the steel cable 10 through an electrically controlled rotating seat 34, and the outer side wall of the sediment sampling barrel 27 is fixedly connected to the impeller part 28. The outer side wall of the bottom end of the sediment sampling barrel 27 is rotatably connected to the inner side wall of the top end of the notched sleeve 29. The bottom end of the notched sleeve 29 is fixedly connected to the anchoring protrusion 31 through multiple bursting discs 30. The rotary extraction assembly consists of a telescopic shaft 32 and a dragon blade 33. The outer side wall of the telescopic shaft 32 is fixedly connected to the inner side wall of the dragon blade 33. The telescopic shaft 32 is fixedly connected to the sediment sampling barrel 27. A plurality of sampling holes are opened at the bottom end of the sediment sampling barrel 27. The telescopic shaft 32 is rotatably connected to the anchoring protrusion 31. The tops of the notched sleeve 29 and the anchoring protrusion 31 are both made of magnet material. It should be noted that before placing the steel cable 10 below the positioning suspension seat 2 into the water, the anchoring protrusion 31 is first immersed in the water, and the entire sediment sampling barrel 27 and the steel cable 10 are kept in a vertical state, and then the limit of the sediment sampling barrel 27 is released, and the sediment sampling barrel 27 is allowed to fall with the anchoring protrusion 31. The higher weight of the anchoring protrusion 31 makes the center of gravity of the entire structure of the rotary assembly located at the bottom, thereby ensuring that the entire structure remains in a relatively vertical state with the anchoring protrusion 31 when falling. When the sediment sampling barrel 27 moves in the water, the impeller part 28 is impacted and rotates, and continuously generates downward impact power, thereby driving the sediment sampling barrel 27 to rotate together. The rotation of the sediment sampling barrel 27 will drive the telescopic shaft 32 and the dragon blade 33 to rotate together in the notched sleeve 29, and wait for the anchor to be When the fixed protrusion 31 impacts and falls into the seabed mud, the whole structure will instantly decelerate to a stop, and the sediment sampling barrel 27 connected to the telescopic shaft 32 will have an instantaneous contraction and extrusion under the impact of inertia and the rotation of the impeller part 28. Then, the multiple bursting discs 30 on the outside will be compressed and deformed during the extrusion process and explode outward, so that the notched sleeve 29 will contact and magnetically attract the anchoring protrusion 31, and the notch at the bottom of the notched sleeve 29 will open. At this time, the telescopic shaft 32 rotating with the impeller part 28 will drive the dragon blade 33 to rotate, and the plankton deposited at the bottom will be rotated and pressed into the sediment sampling barrel 27. As the rotation stops, the dragon blade 33 has been pressed into the bottom mud, sealing and protecting the bottom of the sediment sampling barrel 27 to ensure that the sampled sample will not be affected by other factors. The above advantages are as follows: the impeller 28 can be used to move in the water to drive the rotation of the sediment sampling tube 27 and the dragon blade 33, and after the anchoring protrusion 31 falls to the ground, the inertia and the impact power of the impeller 28 can be used to pop out the bursting membrane 30 to sample the plankton deposited on the bottom of the ocean.

[0025] When the present invention is in use, the anchoring ladder column 1 is transported to the water area to be monitored, and then the anchoring ladder column 1 is lifted by a lifting machine, so that the V-shaped diverter plate 8 on one side of the anchoring ladder column 1 is installed in the water area to be monitored facing the shore. The lifting operation at sea is an existing technical means, which will not be described in detail here. Then, according to the area of ​​the water area to be monitored, the electric control guide ring 5 is controlled to move on the lifting umbrella column 3, and one end of the two-way pushing column 6 moves up with the electric control guide ring 5, and the other end of the two-way pushing column 6 will push the oblique support column 7 obliquely, so that the multiple oblique support columns 7 are synchronously expanded outward, so that the multiple positioning suspension seats 2 are expanded outward, and the positioning suspension seat 2 maintains a relatively horizontal state through rotation adjustment with the oblique support column 7, thereby changing the water area range that the entire equipment can monitor. In this way, the umbrella-shaped structure of the multiple oblique support columns 7 can be changed, so that the area of ​​the multiple oblique support columns 7 expanded is also changed, thereby adjusting the range to be monitored in different water areas and at different times, so that the monitoring operation can be flexible and convenient; During monitoring, the regulating motors 13 on the regulating top platforms 12 on the left and right sides of the anchor ladder column 1 adjust the height of the two-way threaded column 14 between the tensioning bottom platform 9 and the regulating top platform 12 by winding and relaxing the steel cable 10, and adjust the monitoring water depth according to the sea water conditions. When tides appear at sea, the water flow is blocked by the V-shaped diverter plate 8 into two-way water flow, reducing the impact of the water flow on the anchor ladder column 1. The separated side water flow will impact the two impact wheels 18 above and below the reciprocating frame 15, so that the reciprocating frame 15 rotates on the two-way threaded column 14 as the impact wheel 18 rotates, and the knob 16 on the two-way threaded column The reciprocating frame 15 slides in the bidirectional thread groove on the bidirectional thread column 14, so that the reciprocating frame 15 performs a reciprocating motion up and down on the bidirectional thread column 14, thereby driving multiple imaging plankton recorders 17 to rotate synchronously up and down, and take real-time photos of sinking particles and plankton. Combined with AI recognition, automatic classification and counting, when the reciprocating frame 15 first moves to the end, the trigger magnetic ring 19 will approach the open magnetic half ring 26 and generate a magnetic repulsion force on the open magnetic half ring 26, so that the open magnetic half ring 26 moves under the action of the magnetic repulsion force, thereby driving the sealing arc plate 25 and the regulating piston column 24 to move together, and the movement of the sealing arc plate 25 will The sealed space of the main sampling cylinder 20 is opened to allow the water sample of the upper plankton to enter and enter the auxiliary sampling cylinder 22 through the guide tube 21. As the water sample continues to enter, the water sample in the auxiliary sampling cylinder 22 cooperates with the closing spring 23 to synchronously squeeze the regulating piston column 24, and gradually squeezes the regulating piston column 24 to make the sealing arc plate 25 close again. At this time, the water samples in the main sampling cylinder 20 and the auxiliary sampling cylinder 22 are full, and the open magnetic half ring 26 is squeezed by the magnetic repulsion force in the future and cannot push the sealing arc plate 25 to open again, so as to avoid affecting the plankton water sample sampled for the first time in the subsequent process. In the state of static flow or small water flow, Under the condition that the impact wheel 18 is subjected to a small impact force, it is difficult to drive the reciprocating sleeve 15 to rotate on the two-way threaded column 14, thereby avoiding opening the main sampling tube 20 for sampling under a static flow state. The two-way threaded column 14 below each positioning suspension seat 2 maintains a synchronous monitoring and sampling state. In this way, the up and down reciprocating motion of the reciprocating sleeve 15 on the two-way threaded column 14 can be used to monitor the plankton density at different depths under a tidal state. In the initial stage of monitoring, the shallow and deep plankton water samples are sealed and sampled, so that the detection of plankton density is highly accurate while ensuring real-time visualization. The anchoring protrusion 31 is then released to allow the entire sediment sampling tube 27 and the steel cable 10 to remain in a vertical position. The limit of the sediment sampling tube 27 is then released, and the sediment sampling tube 27 is allowed to fall with the anchoring protrusion 31. The higher weight of the anchoring protrusion 31 makes the center of gravity of the entire structure of the rotary assembly located at the bottom, thereby ensuring that the entire structure remains in a relatively vertical state with the anchoring protrusion 31 when falling. When the sediment sampling tube 27 moves in the water, the impeller part 28 is impacted and rotates, and continuously generates downward impact power, thereby driving the sediment sampling tube 27 to rotate together. The rotation of the sediment sampling tube 27 will drive the telescopic shaft 32 and the dragon blade 33 to rotate together in the notched sleeve 29. When the anchoring protrusion 31 impacts and falls into the seabed mud, the entire structure will instantly decelerate to a stop, and the sediment sampling tube 27 connected to the telescopic shaft 32 will be in a state of inertia and Under the impact of the rotation of the impeller 28, there will be an instantaneous contraction and extrusion, and the multiple bursting membranes 30 on the outside will be compressed and deformed during the extrusion process and explode outward, so that the notched sleeve 29 is magnetically attracted to the anchoring protrusion 31, and the notch at the bottom of the notched sleeve 29 is opened. At this time, the telescopic shaft 32 rotates with the rotation of the impeller 28, which drives the dragon blade 33 to rotate, and the plankton deposited at the bottom is rotated and pressed into the sediment sampling tube 27. As the rotation stops, the dragon blade 33 has been pressed into the bottom soil, sealing and protecting the bottom of the sediment sampling tube 27 to ensure that the sampled sample will not be affected by other factors. In this way, the impeller 28 can be used to move in the water to drive the rotation of the sediment sampling tube 27 and the dragon blade 33, and after the anchoring protrusion 31 falls to the ground, the inertia and the impact power of the impeller 28 are used to pop out the bursting membrane 30 to perform sampling operations on the plankton deposited on the bottom of the ocean.
