Description

Technical Field

[0001] The present invention relates to the technical field of fishery breeding, and in particular to a breeding enclosure net for marine fisheries capable of monitoring environmental pollution. Background Art

[0002] With the rapid development of marine fishery aquaculture, aquaculture enclosures, as important aquaculture facilities, have a direct impact on aquaculture efficiency and economic benefits due to their performance. Traditional aquaculture enclosures mainly use a single-layer net structure, which has exposed many technical limitations in practical applications: Limited interception effect: Traditional purse seines usually adopt a single-layer net structure with a fixed mesh size, which makes it difficult to effectively intercept fish of different sizes, especially small fish or highly maneuverable fish.

[0003] Fixed structure, difficult to adjust: Most existing enclosures are of integral design, which cannot be flexibly expanded or contracted according to the area of ​​aquaculture waters, and are difficult to disassemble and maintain, affecting their efficiency.

[0004] To address these issues, the industry has attempted several improvements, such as adopting a double-layer net structure or improving net materials. However, these improvements often only address partial issues and fail to fundamentally enhance the overall performance of purse seines. In particular, innovations in intelligent and modular design remain insufficient, failing to meet the demands of modern marine aquaculture. Therefore, developing a new type of aquaculture purse that combines efficient interception, environmental monitoring, modular design, and easy maintenance is of great practical significance. Summary of the Invention

[0005] The main purpose of this invention is to overcome the shortcomings of the existing technology and provide a marine fishery aquaculture enclosure capable of monitoring environmental pollution. This aquaculture enclosure not only improves fish interception effectiveness but also achieves modularization, intelligentization, and environmental friendliness, providing an efficient and reliable aquaculture solution for modern marine fisheries.

[0006] The technical solution adopted by the present invention to achieve its technical purpose is: a breeding enclosure net for marine fisheries capable of monitoring environmental pollution, comprising an outer shell, a first layer of net arranged inside the outer shell, and the first layer of net being installed inside the outer shell through a linkage assembly; A second layer of net is further provided inside the shell. The second layer of net is provided on one side of the first layer of net. The second layer of net and the first layer of net form a stacked cross structure. The main frame of the housing houses the first and second net layers. The first net layer is secured to the housing via a linkage assembly and provides initial fish interception. The second net layer is positioned to one side of the first net layer, forming a stacked, cross-shaped structure with the first net layer to enhance interception effectiveness. The housing and first net layer are detachably connected via a linkage assembly for easy replacement or maintenance. The housing and second net layer are secured with screws to form a stable structure.

[0007] The sidewall of the enclosure is equipped with a connection detection component, which connects the enclosure and its internal first and second layers of mesh in a modular manner. The connection detection component then monitors the surrounding water environment. The connection detection component is installed on the sidewall of the enclosure and is used to modularly connect multiple enclosure units and monitor the water environment, enabling modular expansion and environmental monitoring of the enclosure.

[0008] Preferably, the housing is configured as a square frame plate structure, with a mounting slot and an embedded slot provided inside the housing; The installation slot is connected to one side of the shell and is used for placing the first layer of net; the linkage component fixes the first layer of net through the installation slot to ensure its stability.

[0009] The embedded groove is connected to the interior of the frame of the outer shell to form a convex structure for fixing the second layer of net; the screw fixing method makes the second layer of net close to the first layer of net to form a stacked structure.

[0010] Preferably, the first layer of net includes an edge strip, an outer rope net and through holes; The outer rope net is a rope net structure with multiple pores, and the pores are square or parallelogram structures; the edging strip is wrapped around the outer periphery of the outer rope net, and multiple thin steel wires are fixed inside it; the through holes are opened at the edge of the edging strip, distributed in a rectangular shape, and iron rings are arranged inside the through holes.

[0011] The edging strips are integrally connected to the outer rope net to enhance structural strength. The through holes cooperate with the linkage components, allowing the pins to pass through the through holes to secure the first layer of net, ensuring detachability.

[0012] Preferably, the linkage assembly includes a frame plate, a bayonet, a spring and a positioning sleeve; The bayonet is a T-shaped structure, one end of which passes through the housing and extends to the outside, and the other end is sleeved with a spring; One end of the spring is fixed to the outer wall of the housing, and the other end is fixed to the bayonet pin; The positioning sleeve is fixed inside the shell and communicated with the through hole, and is used for inserting the rod body of the bayonet pin.

[0013] The outer walls of one end of the T-shaped plurality of the bayonet pins are fixedly connected via a frame plate to achieve synchronous control.

[0014] The bayonet and the through-hole are plugged into each other to fix the first layer of mesh; the spring and the bayonet provide elastic force to ensure that the bayonet is stably engaged; the positioning sleeve and the bayonet guide the bayonet to be inserted accurately, thereby improving installation efficiency.

[0015] At the same time, the frame plate and the pin are linked to facilitate the simultaneous operation of multiple pins, thereby improving the efficiency of disassembly and assembly.

[0016] Preferably, the second layer of net comprises a convex frame and an inner rope net; One end of the protrusion of the convex frame is located inside the frame of the outer shell, and the other end is fixed in the embedded groove by screws; The pores of the inner rope net are in a shuttle-shaped structure, and the edges thereof are fixed inside the raised end of the convex frame.

[0017] The convex frame is fixed to the outer shell with screws to ensure the stability of the second layer of net. The inner and outer rope nets are tightly attached to form a stacked cross structure, which reduces the gaps and enhances the interception effect.

[0018] Preferably, the connection detection assembly comprises a bridging plate, a detection head and a bridging column; The bridge plates are fixed on the side walls of the housing on two adjacent sides, and a detection head is installed between two adjacent bridge plates; The bridging columns are fixed on the other two adjacent side walls of the housing and are rotatably connected to the bridging plates.

[0019] The bridge plate and the detection head are fixedly installed to evenly distribute the detection points. The bridge column and the bridge plate are connected by a rotating shaft to achieve flexible expansion of the fence.

[0020] Preferably, the detection head is used to detect water pollution in the surrounding waters, fill the gaps in the modular connections, and monitor the water environment in real time.

[0021] Preferably, the bridging plate and the bridging column are connected by a rotating shaft to realize a modular combination of multiple shells to adapt to different water area requirements.

[0022] Preferably, the first layer of net and the second layer of net can be disassembled and used separately, and a single-layer or double-layer structure can be selected according to actual needs to improve the applicability and maintenance convenience of the fence.

[0023] Compared with the prior art, the present invention has the following beneficial effects: The aquaculture enclosure net for marine fisheries capable of monitoring environmental pollution can achieve double-layer interception and enhance the anti-escape effect: through the stacked cross structure of the first layer of net (2) and the second layer of net (5) (the pores of the outer rope net 202 are square / parallelogram-shaped, and the pores of the inner rope net 502 are shuttle-shaped), a composite interception barrier is formed to effectively prevent fish of different sizes from escaping.

[0024] The aquaculture enclosure for marine fisheries capable of monitoring environmental pollution can realize modular design and flexible expansion: a connection detection component (4) is provided on the side wall of the shell (1), and is connected by a rotating shaft of a bridge plate (401) and a bridge column (403), thereby realizing rapid combination of multiple modules and adapting to the needs of different aquaculture waters.

[0025] The aquaculture enclosure for marine fisheries capable of monitoring environmental pollution has an integrated environmental monitoring function: detection heads (402) are evenly distributed at the connection points of the enclosure, monitor water pollution parameters in real time, fill the gaps between modules, and provide environmental data, thereby facilitating intelligent aquaculture management.

[0026] The aquaculture enclosure net for marine fisheries capable of monitoring environmental pollution can be quickly assembled and disassembled, and is convenient to maintain: the linkage assembly (3) adopts a spring (303) and a latch (302) structure to achieve rapid replacement of the first layer of net (2); the second layer of net (5) is fixed by screws, which is convenient for separate disassembly, cleaning or replacement, thereby reducing maintenance costs.

[0027] The aquaculture enclosure net for marine fisheries capable of monitoring environmental pollution has the functions of stable structure, corrosion resistance and durability: the edging strip (201) is built with fine steel wire to enhance tensile strength, and the outer shell (1) adopts an anti-corrosion frame to extend the service life of the enclosure net.

[0041] See also Figure 1-Figure 4A breeding enclosure net for marine fisheries capable of monitoring environmental pollution includes an outer shell 1, a first layer of net 2 is arranged inside the outer shell 1, and the first layer of net 2 is installed inside the outer shell 1 through a linkage component 3; a second layer of net 5 is also arranged inside the outer shell 1, and the second layer of net 5 is arranged on one side of the first layer of net 2, and the second layer of net 5 and the first layer of net 2 form a stacked cross structure.

[0042] A connection detection component 4 is provided on the side wall of the shell 1 , through which the shell 1 and the first layer of network 2 and the second layer of network 5 inside it are modularly connected, and then the connection detection component 4 is used to detect the surrounding water environment.

[0043] The outer shell 1 is configured as a square frame structure, and a mounting groove 101 and an embedded groove 102 are provided inside the outer shell 1; the mounting groove 101 is communicated with one side of the outer shell 1, and the first layer of net 2 is placed inside the mounting groove 101 through one side of the outer shell 1, and then the first layer of net 2 is fixed inside the outer shell 1 through the linkage component 3; the embedded groove 102 is communicated with the inside of the frame of the outer shell 1, forming a convex structure with the inside of the frame of the outer shell 1, and the second layer of net 5 is fixed to the embedded groove 102 and the inside of the frame of the outer shell 1 by screws; at the same time, the second layer of net 5 is just in close contact with the first layer of net 2.

[0044] Specifically, during use, the outer shell 1 serves as the main frame. The first and second net layers 2 and 5 must first be installed through the mounting slots 101 and embedded slots 102, respectively. The mounting slots 101 are used to position the first net layer 2 and secure it via the linkage assembly 3. The embedded slots 102 secure the second net layer 5 with screws, ensuring it adheres closely to the first net layer 2 to form a stacked structure. The connection and detection assembly 4 on the sidewall of the outer shell 1 is used for modular connection to other enclosure units and for mounting a detection head 402 for water quality monitoring. Example 2

[0045] See also Figure 1-Figure 5 Based on the above embodiment, this marine fishery aquaculture enclosure capable of monitoring environmental pollution comprises a first layer 2 comprising a edging strip 201, an outer rope net 202, and through holes 203. The outer rope net 202 is configured as a rope net structure with multiple pores arranged in a square or parallelogram configuration. The outer rope net 202 is wrapped with an edging strip 201 for integral connection. Multiple thin steel wires are fixed within the edging strip 201 to increase its hardness and tensile strength. Multiple through holes 203 are formed along the edge of the edging strip 201. The through holes 203 are arranged in a rectangular configuration, with opposing sides aligned with each other. Iron rings are positioned within the through holes 203 to expand and shape the through holes 203, with the edges of the iron rings secured to the edging strip 201.

[0046] Specifically, during use, the first layer of net 2 consists of a edging strip 201, an outer rope net 202, and through-holes 203. During use, the edging strip 201 is inserted into the mounting slot 101 of the outer shell 1, with the through-holes 203 aligned with the latches 302 of the linkage assembly 3. Insertion of the latches 302 secures the first layer of net 2. The porous structure of the outer rope net 202 is designed to intercept fish, while the fine steel wire of the edging strip 201 enhances tensile strength and ensures structural stability.

[0047] The solution in this embodiment can be selectively combined with the solutions in other embodiments for use. Example 3

[0048] See also Figure 1 、 Figure 2 、 Figure 4 、 Figure 6 and Figure 7 Based on the above embodiment, this marine fishery aquaculture enclosure capable of monitoring environmental pollution features a second net layer 5 comprising a convex frame 501 and an inner rope net 502. The convex frame 501 is configured as a shaped frame, with one protruding end located within the outer shell 1 and the other end screwed into the inner recess 102. The other end of the convex frame 501 is flush with the outer wall of the outer shell 1. The inner rope net 502 has a shuttle-shaped aperture, with its edges secured within the raised end of the convex frame 501. One side of the inner rope net 502 is flush with the raised end of the convex frame 501.

[0049] When the convex frame 501 is fixed inside the frame of the outer shell 1 and in the embedded groove 102, the inner rope net 502 is close to the outer rope net 202. At the same time, the protruding end of the convex frame 501 just presses against the edging strip 201, so that the inner rope net 502 in the second layer of net 5 and the outer rope net 202 in the first layer of net 2 form a stacked cross structure, making the pores of the inner rope net 502 and the pores of the outer rope net 202 narrower, and the pore structure more complex and tight, which makes it easier to control the fish within the water area of ​​the aquaculture enclosure.

[0050] Specifically, during use, the second net layer 5 comprises a convex frame 501 and an inner rope net 502. During installation, the raised end of the convex frame 501 is inserted into the interior of the outer shell 1, and the other end is screwed into the inner slot 102, so that the inner rope net 502 is tightly attached to the outer rope net 202 of the first net layer 2. The shuttle-shaped apertures intersect with the apertures of the first net layer 2, enhancing the interception effect and preventing fish from escaping.

[0051] The solution in this embodiment can be selectively combined with the solutions in other embodiments for use. Example 4

[0052] See also Figure 1-Figure 4Based on the above embodiment, the marine fishery aquaculture enclosure capable of monitoring environmental pollution comprises a linkage assembly 3 including a frame plate 301, a latch 302, a spring 303, and a positioning sleeve 304. When the first layer of net 2 is fixedly mounted within the housing 1, that is, when the edging strip 201 of the first layer of net 2 is located within the mounting groove 101 of the housing 1, the through hole 203 is positioned by the latch 302, thereby securing the first layer of net 2 within the housing 1.

[0053] The bayonet 302 is set to a T-shaped structure, and the T-shaped end of the bayonet 302 extends through the shell 1 to the outside. A spring 303 is sleeved on the outside of the T-shaped end of the bayonet 302. One end of the spring 303 is fixed to the outer wall of the shell 1, and the other end is fixed to the T-shaped end of the bayonet 302; the spring 303 is in a tensioned state, which enables the bayonet 302 to pass through the through hole 203 to position the edging strip 201 of the first layer of net 2 inside the installation groove 101 of the shell 1, thereby fixing the first layer of net 2 inside the shell 1.

[0054] One end of the rod of the bayonet 302 is sleeved with a positioning sleeve 304 , which is fixed inside the housing 1 and communicates with the through hole 203 . When the spring 303 is in a tensioned state, the rod of the bayonet 302 is inserted into the positioning sleeve 304 .

[0055] Furthermore, in this embodiment, the outer walls of the T-shaped ends of multiple pins 302 are fixedly connected as a whole through the frame plate 301, and the multiple pins 302 are synchronously controlled by the frame plate 301, so that the multiple pins 302 can be pulled up at the same time to overcome the force of the spring 303, and then one end of the rod body of the multiple pins 302 is passed through the through hole 203 and inserted into the interior of the positioning sleeve 304, so as to facilitate the installation of the first layer of net 2 inside the shell 1.

[0056] Furthermore, in this embodiment, the provision of the linkage assembly 3 facilitates the fixed installation or removal of the first layer of net 2 from the housing 1 .

[0057] When the first net layer 2 is fixedly installed from within the housing 1, the first net layer 2 and the second net layer 5 can be used in combination, forming a stacked cross structure with the second net layer 5. When the first net layer 2 is removed from the housing 1, the second net layer 5 can be used alone. Furthermore, because the second net layer 5 is fixed to the inner groove 102 and the interior of the housing 1 by screws, the second net layer 5 can also be removed, allowing the first net layer 2 to be used alone, effectively increasing the adjustability of the aquaculture enclosure and the efficiency of net replacement.

[0058] Specifically, during use, the linkage assembly 3 is used to quickly install and remove the first layer of net 2. During operation, multiple latches 302 are pulled synchronously through the frame plate 301. After overcoming the elastic force of the spring 303, the first layer of net 2 is placed in the mounting slot 101 of the housing 1. The spring 303 then uses its rebound force to insert the rods of the latches 302 into the through-holes 203 and positioning sleeves 304 of the first layer of net 2, securing the mesh. In other words, after loosening the frame plate 301, the spring 303 rebounds, locking the latches 302, ensuring the secure installation of the first layer of net 2. To remove, the reverse operation is performed.

[0059] The solution in this embodiment can be selectively combined with the solutions in other embodiments for use. Example 5

[0060] See also Figure 1 and Figure 8 Based on the above embodiment, this marine fishery aquaculture enclosure capable of monitoring environmental pollution has a connection detection assembly 4 comprising a bridging plate 401, a detection head 402 for detecting water pollution, and a bridging column 403. Two bridging plates 401 are fixedly mounted on adjacent sidewalls of the housing 1, with a detection head 402 fixedly mounted between the two adjacent bridging plates 401. The detection head 402 can detect water pollution in the surrounding waters, thereby assessing the environmental pollution situation.

[0061] In addition, bridging columns 403 are fixedly provided on the side walls on two adjacent sides of the shell 1, and the bridging columns 403 can maintain a rotational connection with the bridging plate 401; by arranging multiple shells 1, the bridging columns 403 and the bridging plates 401 on the multiple shells 1 are connected through a rotating shaft, thereby realizing a modular combination connection of the multiple shells 1, and can adopt shells 1, the first layer of net 2 and the second layer of net 5 of different areas according to the different areas required to surround the water area, thereby realizing flexible setting.

[0062] Furthermore, in this embodiment, each two bridging plates 401 are fixed oppositely to each other along the maximum length of the side wall of the housing 1. This arrangement, on the one hand, prevents the generation of large gaps at the common connection of multiple housings 1 after modular assembly when the bridging plates 401 and bridging columns 403 are connected. On the other hand, the detection heads 402 can be fixedly installed between two adjacent bridging plates 401, which not only facilitates the positioning of the detection heads 402, but also ensures that the positions of the detection heads 402 are evenly distributed. More importantly, the detection heads 402 can also fill the gaps generated at the common connection of multiple housings 1 after modular assembly.

[0063] Specifically, during use, the connection detection assembly 4 is used for modular expansion of the enclosure and environmental monitoring. During installation, the bridging column 403 is connected to the bridging plate 401 of the adjacent housing 1 via a rotating shaft, thereby assembling multiple housings 1. The detection head 402 is fixed between adjacent bridging plates 401 to monitor water pollution in real time. The modular design allows for flexible adjustment of the enclosure area, and the detection head 402 can also fill gaps at the joints.

[0064] It should be noted that when the aquaculture enclosure is assembled in a modular manner, in order to facilitate the bridging column 403 to maintain a rotational connection with the bridging plate 401 and to allow ropes or other traction ropes to pass through the inside of the bridging plate 401 and the bridging column 403, the detection head 402 is not installed on the outermost bridging plate 401, so that the aquaculture enclosure can be connected by passing ropes or other traction ropes through the inside of the bridging plate 401 and the bridging column 403, thereby facilitating the actual use of the aquaculture enclosure.

[0065] In addition, small through holes are opened inside the bridging column 403 and the bridging plate 401, so that the bridging column 403 and the bridging plate 401 can be connected through a rotating shaft, and the outermost bridging plate 401, the bridging column 403 and the rope or other traction rope can be connected for use.

[0066] The solution in this embodiment can be selectively combined with the solutions in other embodiments for use.

[0067] The working principle and specific use process of the aquaculture enclosure net used in marine fisheries to monitor environmental pollution: Main frame: The outer shell 1 adopts a square frame structure, with a mounting groove 101 and an embedded groove 102 inside. The mounting groove 101 is used to fix the first layer of mesh 2, and the embedded groove 102 is fixed with screws to the second layer of mesh 5, forming a stable double-layer structure.

[0068] Interception function: The first layer of net 2 consists of a edging strip 201, an outer rope net 202, and through-holes 203. The outer rope net 202 has square or parallelogram-shaped holes for initial fish interception. The edging strip 201 is built with fine steel wire for enhanced tensile strength, while the through-holes 203 engage with the latches 302 of the linkage assembly 3 for quick assembly and disassembly.

[0069] The second layer of net 5 includes a convex frame 501 and an inner rope net 502. The shuttle-shaped holes of the inner rope net 502 form a stacked cross structure with the outer rope net 202, further reducing the holes and preventing fish from escaping.

[0070] Modular connection and monitoring: The connection detection assembly 4 consists of a bridge plate 401, a detection head 402 and a bridge column 403. The bridge column 403 is connected to the bridge plate 401 of the adjacent housing 1 through a rotating shaft to achieve flexible expansion of the enclosure.

[0071] The detection head 402 is installed between adjacent bridge plates 401 to monitor water pollution in real time and fill the gaps at the module connections to ensure structural sealing.

[0072] Linkage assembly and disassembly mechanism: The linkage assembly 3 includes a frame plate 301, a latch 302, a spring 303, and a positioning sleeve 304. By pulling the frame plate 301, the multiple latches 302 are synchronously controlled, and the spring 303 is compressed and then inserted or pulled out of the through hole 203, thereby realizing the rapid replacement of the first layer of mesh 2.

[0073] Flexible application: The first layer network 2 and the second layer network 5 can be disassembled and used separately. Users can choose single-layer interception or double-layer enhancement mode according to their needs, taking into account both functionality and ease of maintenance.

[0074] This marine fishery aquaculture enclosure that can monitor environmental pollution optimizes the interception effect through a double-layer net structure. Its modular design adapts to different water areas and integrates environmental monitoring functions to achieve intelligent and sustainable management of marine aquaculture.
