Description

Technical Field

[0001] This invention relates to the field of planktonic marine organism harvesting technology, specifically to an automatic planktonic marine organism harvesting system. Background Technology

[0002] Planktonic marine organisms (such as phytoplankton, small jellyfish, fish eggs, larvae and various planktonic larvae) are an important part of the marine ecosystem and have significant research and application value in fields such as fishery resource assessment, marine environmental monitoring, aquaculture feed collection, and extraction of bioactive substances from marine organisms.

[0003] To enhance monitoring and early warning capabilities in the waters surrounding nuclear power plants and address the issue of effective monitoring of nuclear power plant hazards, it is necessary to regularly collect planktonic marine organisms (PHOs). This requires clarifying the species, density, and spatiotemporal distribution characteristics of PHOs, conducting research on their growth, reproduction, and aggregation biological characteristics, and investigating their correlation with environmental factors at water intakes (temperature, salinity, flow velocity, etc.) to achieve dynamic prediction of the risk of PHO blockage at water intakes. Therefore, the need for large-scale, continuous collection of PHOs from the waters surrounding nuclear power plants is increasingly urgent.

[0004] Currently, traditional methods for collecting planktonic marine organisms mainly rely on manual operation or semi-mechanized equipment. Common methods include: using small planktonic nets to be manually towed or deployed from fixed positions, followed by manual rinsing and sample collection; some vessels are equipped with simple winches and nets, but still require significant manual labor for tasks such as setting, retrieving, transferring samples, and cleaning the nets. These existing technologies have the following significant drawbacks in practical applications:

[0005] First, manual trawls or semi-mechanized operations require multiple people to work together, and the process is continuous and tedious. After each sampling, the nets need to be cleaned and the samples transferred manually, making it difficult to achieve long-term, high-frequency continuous retrieval operations, resulting in low overall efficiency.

[0006] Second, existing equipment is mostly fixed or requires towing by large vessels, making it difficult to deploy flexibly in nearshore, shallow water, or complex sea conditions. Fixed-station sampling cannot dynamically track the spatiotemporal distribution changes of planktonic communities, has a limited dredging coverage, and generally lacks automatic collection and drainage functions, requiring full manual intervention. This not only increases labor costs but also limits operational capabilities under adverse weather or nighttime conditions.

[0007] Third, manual net collection, rinsing, and concentration processes cause significant mechanical damage to planktonic organisms, affecting subsequent live culture or morphological studies. Furthermore, standardized collection procedures are difficult to achieve manually, easily compromising sample representativeness.

[0008] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop an automatic planktonic marine organism harvesting system. Summary of the Invention

[0009] The purpose of this invention is to provide an automated system for harvesting planktonic marine organisms to solve the problems mentioned in the background section.

[0010] To achieve the above objectives, the present invention provides the following technical solution:

[0011] A technical solution for an automatic planktonic marine organism salvage system includes a salvage main float, a propeller base at the tail end of the main float, and a propeller mounted on the propeller base. A salvage drive motor is installed inside the main float, and the output end of the drive motor is connected to a drive pulley. A transmission pulley is positioned diagonally above the drive pulley, and a transmission shaft is installed in the shaft hole of the transmission pulley.

A collection net frame is located inside the main float at the outlet end of the salvage conveyor chain.

[0012] As a preferred technical solution, the front end of the salvage main float is also equipped with two sets of extension frames.

The second drive pulley and the second transmission pulley are connected by a second belt. The second transmission pulley is coaxially connected to a first synchronous pulley.

[0014] As a preferred technical solution, the drive shaft is coaxially fixed with a drive sprocket, and the driven shaft is coaxially fixed with a driven sprocket. The drive sprocket and the driven sprocket mesh around the salvage conveyor chain.

[0015] As a preferred technical solution, the second drive pulley is coaxially mounted on the transmission shaft, and the second drive pulley is connected to the second transmission pulley via the second belt. The second transmission pulley is coaxially connected to the first synchronous pulley.

[0016] As a preferred technical solution, the salvage conveyor chain and the centralized guide plate are arranged in a corresponding manner, and the propeller, salvage drive motor and reducer are linked together to form an integrated automatic salvage and transmission structure.

[0017] As a preferred technical solution, the collection net frame is provided with card interfaces on both sides, and the card interfaces are detachably connected to the salvage main float for easy assembly and disassembly.

[0030] The features and exemplary embodiments of various aspects of the present invention will now be described in detail. To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. For those skilled in the art, the present invention can be practiced without some of these specific details. The following description of the embodiments is merely to provide a better understanding of the present invention by illustrating examples of the invention.

[0031] like Figures 1-5 As shown, the automatic planktonic marine organism salvage system of the present invention includes a salvage main float 1, a propeller base 21 at the tail end of the salvage main float 1, a propeller 22 installed on the propeller base 21, and the propeller 22 can drive the entire salvage main float 1 to autonomously navigate and move in near-shore, shallow water or complex sea conditions without the need for large vessels to tow it.

[0032] The main salvage float 1 is equipped with a salvage drive motor 31. The output end of the salvage drive motor 31 is connected to a drive pulley 32. A transmission pulley 33 is arranged diagonally above the drive pulley 32. A transmission shaft 34 is installed in the shaft hole of the transmission pulley 33. The transmission pulley 33 and the drive pulley 32 are connected by a belt 35. A transmission sprocket 36 is mounted on the transmission shaft 34. A driven shaft 37 is rotatably connected inside the main salvage float 1. A driven sprocket 38 is mounted on the driven shaft 37. A salvage conveyor chain 39 is connected between the driven sprocket 38 and the transmission sprocket 36.

[0033] A collection net frame 6 is installed inside the main salvage float 1. The collection net frame 6 is located at the outlet end of the salvage conveyor chain 39. The collection net frame 6 is provided with snap-fit ​​interfaces on both sides. The snap-fit ​​interfaces are detachably snap-fitted to the main salvage float 1 for easy assembly and disassembly. The collection net frame 6 is located at the outlet end of the salvage conveyor chain 39.

[0034] After the salvage drive motor 31 starts, it drives the transmission pulley 33 to rotate via the drive pulley 32 and belt 35, which in turn drives the transmission shaft 34 to rotate synchronously. Through the transmission sprocket 36 and driven sprocket 38, the salvage conveyor chain 39 rotates cyclically. Planktonic marine organisms that enter the salvage area with the main salvage float 1 are gradually transported upwards by the salvage conveyor chain 39 and finally automatically fall into the collection net frame 6 from the outlet end for collection. The entire process requires no manual net setting, net retrieval, or sample transfer, enabling continuous salvage operations for extended periods, significantly improving salvage efficiency and reducing labor costs. Furthermore, the salvage conveyor chain 39 is a flexible transport structure, which avoids mechanical damage to the planktonic organisms, ensuring sample integrity and meeting the needs of subsequent live culture and scientific research.

[0035] Two sets of extension frames 11 are also installed at the front end of the main buoy 1. Each set of extension frames 11 is equipped with a reducer 48 at its top. The input ends of the two sets of reducers 48 are synchronously connected by a centralized connecting shaft 46. A centralized rotating shaft 49 is installed at its output end. A rotating shaft fixing sleeve 50 is fixedly fitted on the outside of the centralized rotating shaft 49. A centralized guide plate 51 is evenly distributed in a circular shape on the outside of the rotating shaft fixing sleeve 50. Several equally spaced elongated holes are provided on the centralized baffle 51 to block planktonic organisms without affecting water flow.

[0036] Two sets of extension frames 11 stably mount the reducer 48, the central rotating shaft 49, and the central guide plate 51 at the front end of the salvage main float 1. The central connecting shaft 46 synchronously drives the two sets of reducers 48 to run. The reducer 48 drives the central rotating shaft 49 to rotate at a constant speed through the output end. The rotating shaft fixing sleeve 50 drives the circumferentially arranged central guide plate 51 to rotate synchronously. The rotating central guide plate 51 can guide the planktonic marine organisms floating on the sea surface to the middle of the salvage main float 1, expand the salvage range, prevent the planktonic marine organisms from escaping from both sides of the salvage main float 1, and improve the efficiency of salvage and collection. At the same time, the guiding effect of the rotating guide plate is gentle and will not cause compression or damage to the planktonic organisms, ensuring the integrity of the sample.

[0037] The output end of the salvage drive motor 31 is also provided with a second drive pulley 41. A second transmission pulley 42 is provided on the adjacent side of the second drive pulley 41. The second drive pulley 41 and the second transmission pulley 42 are connected by a second belt 43. The second transmission pulley 42 is coaxially connected to a first synchronous pulley 44. A second synchronous pulley 45 is mounted on the centralized connecting shaft 46. The first synchronous pulley 44 and the second synchronous pulley 45 are connected by a synchronous belt 47.

[0038] After the salvage drive motor 31 starts, its output end synchronously drives the second drive pulley 41 to rotate. The second drive pulley 41 drives the second transmission pulley 42 to rotate through the second belt 43. The second transmission pulley 42 drives the coaxial first synchronous pulley 44 to rotate. The first synchronous pulley 44 drives the second synchronous pulley 45 to rotate through the synchronous belt 47, which in turn drives the centralized connecting shaft 46 to rotate synchronously. This enables one salvage drive motor 31 to simultaneously drive the salvage conveyor chain 39 and the centralized guide plate 51 to operate. No additional independent power source is required, which simplifies the overall structure of the equipment, reduces the energy consumption and manufacturing cost of the equipment, and ensures that the operating speed of the centralized guide plate 51 and the salvage conveyor chain 39 are matched. The guiding and converging actions are consistent with the salvage and conveying actions, which improves the stability and efficiency of the overall operation.

[0039] A drive shaft 34 is coaxially fixed with a drive sprocket 36, and a driven shaft 37 is coaxially fixed with a driven sprocket 38. The drive sprocket 36 and the driven sprocket 38 mesh around the salvage conveyor chain 39. When the drive shaft 34 rotates, it synchronously drives the coaxially fixed drive sprocket 36 to rotate. The drive sprocket 36 drives the salvage conveyor chain 39 to move cyclically through meshing. The salvage conveyor chain 39 drives the driven sprocket 38 on the driven shaft 37 to rotate synchronously. The meshing transmission connection is stable and reliable, avoiding slippage during transmission and ensuring a stable rotation speed of the salvage conveyor chain 39. This allows for the continuous and stable transport of salvaged planktonic marine life to the collection net frame 6, ensuring the stability of continuous operation.

[0040] Drive pulley 41 is coaxially mounted on drive shaft 34. Drive pulley 41 is connected to drive pulley 42 via belt 43. Drive pulley 42 is coaxially connected to synchronous pulley 44. When drive shaft 34 rotates with drive pulley 33, it synchronously drives drive pulley 41 to rotate. Power is transmitted sequentially through belt 43 and drive pulley 42 to synchronous pulley 44, realizing the synchronous transmission of power from the salvage and conveying mechanism to the guiding and collecting mechanism. This ensures consistent power transmission throughout the system, and the actions of each mechanism can be linked without additional control modules, reducing the complexity of the control system and improving the reliability of equipment operation.

[0041] The salvage conveyor chain 39 and the centralized guide plate 51 are arranged correspondingly at the front and rear. The propeller 22, salvage drive motor 31, and reducer 48 are linked together to form an integrated automatic salvage and transmission structure. The centralized guide plate 51 guides the collected planktonic organisms directly into the salvage range of the corresponding salvage conveyor chain 39. The propeller 22 drives the equipment to move and track the distribution of planktonic organisms. The salvage drive motor 31 drives the centralized guide plate 51 to collect the planktonic organisms and the salvage conveyor chain 39 to transport them, finally automatically storing them in the collection net frame 6. The entire process is fully automated and requires no manual intervention. It can operate continuously at night and in inclement weather conditions. At the same time, the unified linkage process achieves standardized collection, avoids errors caused by manual operation, and improves the representativeness of the samples. In addition, the entire equipment can move flexibly with the propeller, dynamically tracking the spatiotemporal distribution changes of the planktonic community, expanding the salvage coverage area, and adapting to the needs of various operating areas such as nearshore, shallow water, and complex sea conditions.
