Description

Technical Field

[0001] The present invention relates to the technical field of aquaculture cages, in particular to a symbiotic aquaculture cage for mixed aquaculture of sea urchins and sea cucumbers. Background Art

[0002] In the marine aquaculture industry, sea urchins and sea cucumbers, as high-value marine biological resources, have always attracted much attention for their aquaculture technology. However, traditional mixed aquaculture methods often have many problems, especially the mutual interference caused by direct contact between sea urchins and sea cucumbers, which not only affects their growth environment but also may cause the spread of diseases, thereby reducing aquaculture benefits.

[0003] To address this issue, the aquaculture industry has begun exploring zoning solutions, aiming to effectively separate sea urchins and sea cucumbers within the same aquaculture environment, reducing mutual interference and improving aquaculture results. However, existing zoning practices make it difficult to combine sea cucumbers and urchins to address the dietary needs of sea cucumbers. Therefore, we propose a symbiotic aquaculture cage for mixed sea urchin and sea cucumber aquaculture. Summary of the Invention

[0024] As a preferred embodiment of the present invention, the driving part includes a top crossbeam installed on the top frame, the end of the top crossbeam is connected to an L-shaped plate, a second sliding rod is provided on the L-shaped plate, the second sliding rod is slidably connected to a lifting plate, a fourth spring is sleeved on the second sliding rod, the two ends of the fourth spring are respectively abutted against the lifting plate and the L-shaped plate, a stop block is provided on the upper end of the second sliding rod, a first driving part is installed on the lifting plate, the output end of the first driving part is connected to the second rotating shaft, a second driving part is installed on the top crossbeam, the output end of the second driving part is connected to a cam, and the cam is used to drive the lifting plate to slide on the L-shaped plate.

[0025] As a preferred embodiment of the present invention, a mounting plate is installed on the first rotating shaft, and the mounting plate is used to install a support for carrying the sea urchin.

[0026] Compared with the existing technology, the present invention has the following advantages: by installing a vertical second mesh wall within the first mesh wall, the entire cage is divided into two areas. A third mesh wall, capable of accommodating sea urchins, is installed in one of the areas. When sea urchins are cultured within the second mesh wall, their organic-rich feces naturally fall to the bottom of the cage, forming a sediment layer. By periodically rotating the first shaft, the sea urchins' positions are altered, simultaneously driving sea cucumbers back to the original sea urchin culture area, achieving niche exchange. This dynamic zone-switch mechanism enables sea cucumbers to actively ingest sea urchin feces deposited at the bottom, effectively promoting material recycling within the culture system—converting sea urchin metabolic products into natural food for the sea cucumbers. This reduces the amount of artificial feed fed and prevents water quality deterioration caused by fecal accumulation. Furthermore, the economic sea cucumbers in the original sea urchin culture area are naturally purified after their active feeding, providing a clean environment for the next cycle of culture, forming a closed-loop "metabolism-feeding-purification" ecosystem.

[0027] During the bottom frame cleaning operation, by increasing the rotation speed or maintaining the original speed, the second rotating shaft moves downward inside the first rotating shaft to drive the scraper to contact the bottom frame. In the process of the scraper directing the surface dirt to the cleaning port, the specially designed baffle groove structure can selectively retain the sea urchin feces layer containing undecomposed organic matter, and only remove completely mineralized harmful sediments, which not only maintains the continuous supply of sea cucumber bait, but also accurately removes toxic substances. When the spring thruster triggers the baffle to flip, the system can discharge harmful dirt in a targeted manner. Based on the physical isolation of sea cucumbers and sea urchins, this collaborative design, through the coupling of space rotation and material circulation, constructs a co-cultivation system with less human intervention and high material utilization rate, so that the two types of organisms can obtain optimal growth conditions while sharing the same water resources, and the overall breeding efficiency is significantly improved.

DETAILED DESCRIPTION

[0042] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0044] The technical solutions provided by various embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0045] See also Figure 1 - Figure 13 The present invention provides an embodiment: a symbiotic culture cage for mixed culture of sea urchins and sea cucumbers, comprising

[0046] A frame assembly, wherein the outer periphery of the frame assembly is connected to a first mesh wall 105, and a mesh box is formed by the first mesh wall 105;

[0047] A first rotating shaft 201 is rotatably connected to the center of the frame assembly, and an upper crossbar 216 and a lower crossbar 204 are provided on the first rotating shaft 201;

[0048] The second mesh wall 217 is connected between the upper cross bar 216 and the lower cross bar 204, and the edge of the second mesh wall 217 moves in contact with the inner side of the first mesh wall 105;

[0049] A screen frame 219 is mounted on the first rotating shaft 201, and a third screen wall 220 is mounted on the screen frame 219, and the top of the third screen wall 220 has an opening;

[0050] A cleaning assembly, installed at the bottom of the frame assembly, for cleaning the bottom of the frame assembly;

[0051] The sewage discharge component is used to discharge the sewage cleaned by the sewage cleaning component.

[0052] According to the solution of the present invention, the frame assembly constitutes the main body of the cage, the first net wall 105 forms a breeding space around the frame assembly, and the first rotating shaft 201 is located at the center of the frame assembly, which can drive the upper cross bar 216 and the lower cross bar 204 to rotate. The second mesh wall 217 is connected between the upper crossbar 216 and the lower crossbar 204 to form a sea cucumber breeding area, dividing the cage into two parts. Its edge moves in line with the inner side of the first mesh wall 105 to achieve the position change of the sea urchin and sea cucumber areas. The mesh frame 219 is installed on the first rotating shaft 201. The third mesh wall 220 with an opening is used for the placement and management of sea urchins. The cleaning component is installed at the bottom of the frame to clean the dirt, and the sewage discharge component discharges the dirt. During operation, sea urchins are cultured in the second mesh wall 217, and their feces fall to the bottom of the frame. By rotating the first rotating shaft 201, the position of the sea urchins can be changed, and the sea cucumbers can be driven to the original area where the sea urchins were located, realizing position exchange and joint breeding. This solution can achieve the zoned breeding of sea urchins and sea cucumbers, but in the same cage, saving costs and avoiding direct contact between sea urchins and sea cucumbers, reducing mutual interference, and is conducive to their respective growth.

[0053] Optionally, in one embodiment, the frame assembly includes a bottom frame 100, a top frame 101, and a plurality of support rods 102 connected between the bottom frame 100 and the top frame 101, the first rotating shaft 201 is rotatably connected to the bottom frame 100, the lower end of the first mesh wall 105 is installed on the bottom frame 100, and the upper end of the first mesh wall 105 is detachably connected to the top frame 101 via a lifting part 106.

[0054] In one embodiment, the first rotating shaft 201 is a hollow structure, and a through slot 202 is formed on the lower side wall of the first rotating shaft 201;

[0055] The cleaning assembly includes

[0056] A second rotating shaft 203 is installed in the first rotating shaft 201. The second rotating shaft 203 can slide vertically and rotate coaxially with respect to the first rotating shaft 201. The lower cross bar 204 is fixed on the second rotating shaft 203. The lower cross bar 204 is located in the through slot 202 and can slide up and down in the through slot 202.

[0057] A scraper 205 is installed at the bottom of the lower crossbar 204. In a natural state, the scraper 205 is separated from the bottom frame 100. A sewage cleaning port 110 is provided on the bottom frame 100. Each sewage cleaning port 110 is provided with a baffle plate 111. The baffle plate 111 is connected to the sewage cleaning port 110 through a torsion spring. In a natural state, the baffle plate 111 blocks the sewage cleaning port 110 through the torsion spring.

[0058] A spring thruster is installed on the lower cross bar 204. When the scraper 205 contacts the surface of the bottom frame 100 and the spring thruster is located above the sewage cleaning port 110, the spring thruster drives the baffle plate 111 to open, and the sewage is discharged through the sewage cleaning port 110. The driving part is used to drive the second rotating shaft 203 to slide up and down in the first rotating shaft 201.

[0059] With such a solution, the scraper 205 is installed at the bottom of the lower cross bar 204, and the vertical sliding and coaxial rotation of the second rotating shaft 203 in the first rotating shaft 201 are used to realize the up and down movement and rotation of the scraper 205. In the natural state, the scraper 205 is separated from the bottom frame 100. In this state, the scraper 205 does not contact the dirt on the surface of the bottom frame 100 due to the rotation of the first rotating shaft 201, but the gap between the scraper 205 and the bottom frame 100 is smaller than the gap of the sea cucumber, which can drive the sea cucumber to move to the next area. The rotation speed of the first rotating shaft 201 is slow movement, not fast movement. When the bottom frame 100 needs to be cleaned, the rotation speed can be appropriately increased or maintained at the original speed. At the same time, the second rotating shaft 203 moves downward in the first rotating shaft 201. The scraper 205 moves and drives the scraper 205 to contact the bottom frame 100. At this time, the sea cucumber's feces and other dirt are scraped to the cleaning port 110 through the scraper 205. Since the top surface of the baffle plate 111 is not flush with the surface of the bottom frame 100, but forms a groove in the downward position, after the dirt enters the groove, the scraper 205 will not scrape away the dirt in the groove when passing through. As the scraper 205 continues to move, the spring thruster contacts the baffle plate 111 and drives the baffle plate 111 to flip and squeeze the torsion spring. At this time, the baffle plate 111 opens, and the dirt is discharged through the cleaning port 110. This solution, while being applicable to the background of the sea urchin and sea cucumber co-cultivation cage, can also improve the cleaning effect of the dirt, effectively remove harmful substances in the water body, and provide a healthier growth environment for sea cucumbers and sea urchins.

[0060] In one embodiment, the sewage discharge assembly includes

[0061] A bottom cover 107 is installed at the bottom of the bottom frame 100. The bottom cover 107 is sealed to the bottom frame 100, and a sewage outlet 108 is provided at the bottom of the bottom cover 107.

[0062] The pipeline assembly 109 is installed at the bottom of the sewage outlet 108 and is used to transport the sewage at the sewage outlet 108 to the outside.

[0063] With this solution, the pipe assembly 109 is installed at the bottom of the sewage outlet 108. Its function is to effectively transport the dirt at the sewage outlet 108 to the outside, thereby achieving the discharge and cleaning of the dirt. The pipe assembly 109 includes but is not limited to water pumps, pipes and other equipment for transporting liquids.

[0064] In order to prevent the sewage outlet 108 from being blocked, in one embodiment, the lower end of the first rotating shaft 201 passes through the bottom frame 100 and extends into the bottom cover 107 and is located at the center of the sewage outlet 108. A scraping mechanism is installed on the first rotating shaft 201, and the scraping mechanism is used to clean the sewage outlet 108.

[0065] By adopting such a solution, in order to prevent the sewage outlet 108 from being blocked, the lower end of the first rotating shaft 201 is designed to pass through the bottom frame 100 and extend to the inside of the bottom cover 107, and its position is exactly at the center of the sewage outlet 108. A scraper mechanism is installed on the first rotating shaft 201. When the first rotating shaft 201 rotates, the scraper mechanism will rotate accordingly and clean the sewage outlet 108, scraping off the dirt that may block the sewage outlet 108, ensuring the smooth flow of the sewage outlet 108. This embodiment cleans the sewage outlet 108 through the scraper mechanism, effectively preventing the sewage outlet 108 from being blocked, and brings about the effects of improving sewage discharge efficiency, reducing maintenance costs and extending service life.

[0066] In one embodiment, the scraping mechanism includes a shell 212 installed at the bottom of the first rotating shaft 201, a gap is provided in the middle of the shell 212, and two symmetrical rotating rods 213 are rotatably connected in the gap, and one end of the two rotating rods 213 close to the sewage outlet 108 is connected to a cleaning plate 214, a first cavity 206 and a second cavity 209 are provided in the first rotating shaft 201, and the second cavity 209 is located below the first cavity 206, a first through hole 2102 is provided in the first rotating shaft 201, and a second push rod 210 is slidably connected in the first through hole 2102, a baffle 2101 is installed on the second push rod 210, and a second spring 211 is sleeved on the second push rod 210, and the second spring 2 The two ends of 11 are respectively against the second cavity 209 and the bottom wall of the second cavity 209, the bottom of the lower cross bar 204 is connected to the first push rod 207, the lower end of the first push rod 207 is located in the first cavity 206, and the first push rod 207 is sleeved with a first spring 208 whose two ends are respectively against the bottom wall of the first cavity 206 and the lower cross bar 204. When the second rotating shaft 203 drives the scraper 205 to fit with the bottom frame 100, the first push rod 207 is against the second push rod 210 and drives the second push rod 210 to move downward, and the second push rod 210 pushes the rotating rod 213 to rotate, so that the rotating rod 213 drives the cleaning plate 214 to be folded and contracted to increase the passage area of the sewage outlet 108.

[0067] With this solution, when the scrapers 205 move toward each other and contact the surface of the bottom frame 100, it indicates that the cage has entered the dirt cleaning stage. In order to maximize the passage area of the sewage outlet 108 for smooth sewage discharge, the cleaning plate 214 needs to be folded. At this time, the second rotating shaft 203 moves downward, driving the scraper 205 to fit the surface of the bottom frame 100. At the same time, the first push rod 207 contacts the second push rod 210, driving the rotating rod 213 to rotate, so that the cleaning plate 214 is folded and contracted, thereby increasing the passage area of the sewage outlet 108. When the scraper 205 is separated from the bottom frame 100 and reset, the second push rod 210 and the first push rod 207 are reset under the interaction of each spring, and the rotating rod 213 is reset with gravity. At this time, when the first rotating shaft 201 rotates, the cleaning plate 214 cleans the sewage outlet 108. At this time, since the scraper 205 is not in contact with the bottom frame 100, it is not the sewage discharge time. The cleaning plate 214 can ensure the cleanliness of the sewage outlet 108 and avoid blockage. This embodiment maximizes the passage area of the sewage outlet 108 through the folding and contraction of the cleaning plate 214, ensuring that the sewage can be discharged quickly, thereby improving the sewage discharge efficiency.

[0068] In one embodiment, a vibrator is sealed in the shell 212, a metal segment 2103 is provided on the second push rod 210, and a first conductive ring 2104 and a second conductive ring 2105 are provided on the inner side of the first through hole 2102. The first conductive ring 2104 and the second conductive ring 2105 are electrically connected to the vibrator. When the metal segment 2103 contacts the first conductive ring 2104 and the second conductive ring 2105, a closed loop is formed and the vibrator is energized.

[0069] With this solution, when the metal segment 2103 on the second push rod 210 contacts the first and second conductive rings 2104 and 2105, a closed circuit is formed, energizing the vibrator and starting operation. The vibrator vibrates under the action of electricity, achieving the vibratory cleaning effect of the rotating rod 213 and the cleaning plate 214.

[0070] In one embodiment, the spring thruster includes a first slide bar 300 installed on the lower cross bar 204, the upper end of the first slide bar 300 is connected to a connecting rod 301, the lower end of the first slide bar 300 is connected to a roller bracket 302, the roller bracket 302 is rotatably connected to a roller body 303, and the first slide bar 300 is sleeved with a third spring 304, and the two ends of the third spring 304 are respectively against the lower cross bar 204 and the roller bracket 302. In a natural state, the roller body 303 is located below the scraper 205.

[0071] When the roller body 303 contacts the material baffle plate 111, the third spring 304 sleeved on the first slide bar 300 is deformed due to the rotation of the roller body 303 and the movement of the roller bracket 302 connected thereto, and a vibration-driving plate with multiple protrusions is provided at the bottom of the connecting rod 301, which is slidably connected to the lower cross bar 204. When the roller body 303 contacts the material baffle plate 111, the vibration generated by the vibration-driving plate and the lower cross bar 204 is transmitted to the material baffle plate 111 through the roller body 303, thereby shaking the material baffle plate 111 while it is opened, thereby improving the discharge effect. The shaking of the material baffle plate 111 helps the material to slide more smoothly, reducing the residue of material on the material baffle plate 111, thereby improving the discharge effect. Due to the shaking of the material baffle plate 111, the material is not easy to accumulate at the discharge port, reducing the risk of blockage.

[0072] In one embodiment, the driving part includes a top crossbeam 103 installed on the top frame 101, the end of the top crossbeam 103 is connected to an L-shaped plate 104, the L-shaped plate 104 is provided with a second slide bar 406, the second slide bar 406 is slidably connected to the lifting plate 200, the second slide bar 406 is sleeved with a fourth spring 408, the two ends of the fourth spring 408 are respectively against the lifting plate 200 and the L-shaped plate 104, a stop block 407 is provided at the upper end of the second slide bar 406, a first driving part 400 is installed on the lifting plate 200, the output end of the first driving part 400 is connected to the second rotating shaft 203, a second driving part 402 is installed on the top crossbeam 103, the output end of the second driving part 402 is connected to a cam 403, and the cam 403 is used to drive the lifting plate 200 to slide on the L-shaped plate 104.

[0073] With this solution, the second driving unit 402 drives the cam 403 to rotate, and the rotational movement of the cam 403 is converted into the sliding of the lifting plate 200 on the second slide rod 406, thereby realizing the up and down movement of the lifting plate 200. At the same time, the first driving unit 400 is installed on the lifting plate 200, and its output end is connected to the second rotating shaft 203. Therefore, when the lifting plate 200 moves up and down, the first driving unit 400 moves up and down synchronously, and at the same time, the first driving unit 400 can also synchronously drive the second rotating shaft 203 and the first rotating shaft 201 to rotate.

[0074] Optionally, in one embodiment, a mounting plate 218 is mounted on the first rotating shaft 201 , and the mounting plate 218 is used to mount a support for the sea urchin, which may be an object such as a reef where the sea urchins often inhabit.

[0075] The present invention divides the entire cage into two areas by arranging a vertical second mesh wall 217 within the first mesh wall 105, and installs a third mesh wall 220 capable of accommodating sea urchins in one of the areas. During operation, sea urchins are cultured within the second mesh wall 217, and their feces fall to the bottom of the frame. By rotating the first rotating shaft 201, the position of the sea urchins can be changed, and the sea cucumbers can be driven to the area where the sea urchins were originally located, realizing position exchange and joint culture. This allows for the regional culture of sea urchins and sea cucumbers, while still within the same cage, saving costs and avoiding direct contact between the sea urchins and sea cucumbers, reducing mutual interference and facilitating their respective growth.

[0076] When the bottom frame 100 needs to be cleaned, the rotation speed can be appropriately increased or maintained at the original speed. At the same time, the second rotating shaft 203 moves downward in the first rotating shaft 201 and drives the scraper 205 to contact the bottom frame 100. At this time, the scraper 205 scrapes the sea cucumber's feces and other dirt to the cleaning port 110. Since the top surface of the baffle plate 111 is not flush with the surface of the bottom frame 100, but forms a groove in the downward position, after the dirt enters the groove, the scraper 205 will not scrape away the dirt in the groove when passing through. As the scraper 205 continues to move, the spring thruster contacts the baffle plate 111 and drives the baffle plate 111 to flip and squeeze the torsion spring. At this time, the baffle plate 111 is opened, and the dirt is discharged through the cleaning port 110. Under the premise of being applicable to the background of the sea urchin and sea cucumber co-cultivation cage, it can also improve the cleaning effect of dirt, effectively remove harmful substances in the water body, and provide a healthier growth environment for sea cucumbers and sea urchins.

[0077] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
