[0002] In the marine aquaculture industry, sea urchins and sea cucumbers are high-value marine biological resources, and their aquaculture technology has always attracted much attention. 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 may also cause disease transmission, thereby reducing aquaculture benefits. In order to solve this problem, the aquaculture industry has begun to explore the technical solution of zoned aquaculture, in order to effectively separate sea urchins and sea cucumbers in the same aquaculture environment, reduce mutual interference, and improve aquaculture results. However, the existing zoned aquaculture is not convenient for combining sea cucumbers and sea urchins to solve the problem of sea cucumber diet.

[0014] Compared with the prior art, the present invention has the following beneficial effects: the present invention divides the entire cage into two areas by setting a vertical second net wall in the first net wall, and installs a third net wall that can accommodate sea urchins in one of the areas. When sea urchins are cultured in the second net wall, their feces rich in organic matter naturally fall to the bottom of the frame to form a sediment layer. By periodically rotating the first rotating shaft to change the position of the sea urchins, the sea cucumbers are synchronously driven to the original sea urchin culture area to achieve niche exchange. This dynamic zone exchange mechanism enables sea cucumbers to actively ingest the sea urchin feces deposited at the bottom, effectively promoting the recycling of materials in the culture system - the metabolites of sea urchins are converted into natural bait for sea cucumbers, which not only reduces the amount of artificial feed fed, but also avoids the deterioration of water quality caused by feces accumulation. At the same time, the economic sea cucumbers in the original sea urchin culture area are naturally purified after feeding, providing a clean environment for the next round of zone exchange culture, forming a closed-loop ecosystem of "metabolism-feeding-purification".

[0015] 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. While the scraper guides the surface dirt to the cleaning port, the specially designed baffle plate groove structure can selectively retain the sea urchin feces layer containing undecomposed organic matter, and only removes 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 plate 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 has constructed a co-cultivation system with less human intervention and high material utilization rate through the coupling of space rotation and material circulation, 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

[0018] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. 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 making creative work are within the scope of protection of the present invention.

[0019] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0021] See also Figure 1 - Fig.13 The present invention provides an embodiment: a symbiotic culture cage for mixed culture of sea urchins and sea cucumbers, comprising: A frame assembly, wherein the outer periphery of the frame assembly is connected with a first mesh wall 105, and a mesh box is formed by the first mesh wall 105; A first rotating shaft 201, rotatably connected to the center of the frame assembly, and an upper cross bar 216 and a lower cross bar 204 are provided on the first rotating shaft 201; 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; 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; A cleaning assembly, installed at the bottom of the frame assembly, for cleaning the bottom of the frame assembly; The sewage discharge component is used to discharge the sewage cleaned by the sewage cleaning component.

[0022] According to the solution of the present invention, the frame assembly constitutes the main body of the cage, the first net wall 105 surrounds the frame assembly to form a breeding space, 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 cross bar 216 and the lower cross bar 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 areas where the sea urchins and sea cucumbers are located. 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 to achieve position exchange and joint breeding. This solution can achieve the zoned breeding of sea urchins and sea cucumbers, but in the same mesh cage, saving costs and avoiding direct contact between sea urchins and sea cucumbers, reducing mutual interference, and is beneficial to their respective growth. 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 portion 106.

[0023] In one embodiment, the first rotating shaft 201 is a hollow structure, and a through slot 202 is formed on the side wall below the first rotating shaft 201; The cleaning assembly includes A second rotating shaft 203 installed in the first rotating shaft 201, the second rotating shaft 203 can slide vertically and rotate coaxially relative 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 slides up and down in the through slot 202; A scraper 205 installed at the bottom of the lower crossbar 204 is separated from the bottom frame 100 in a natural state; a sewage cleaning port 110 is provided on the bottom frame 100, and each sewage cleaning port 110 is provided with a baffle plate 111, which 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; 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.

[0024] With such a solution, the scraper 205 is installed at the bottom of the lower cross bar 204, and the vertical movement and rotation of the scraper 205 are realized by the vertical sliding and coaxial rotation of the second rotating shaft 203 in the first rotating shaft 201. In a 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 a groove is formed in the downward position, after the dirt enters the groove, the scraper 205 will not scrape away the dirt in the groove when passing by. 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. 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, and provide a healthier growth environment for sea cucumbers and sea urchins.

[0025] In one embodiment, the sewage discharge assembly includes A bottom cover 107 installed at the bottom of the bottom frame 100, the bottom cover 107 is sealedly connected to the bottom frame 100, and a sewage outlet 108 is provided at the bottom of the bottom cover 107; 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.

[0026] 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.

[0027] 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 scraper mechanism is installed on the first rotating shaft 201, and the scraper mechanism is used to clean the sewage outlet 108.

[0028] By adopting such a scheme, 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 to ensure 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.

[0029] In one embodiment, the scraper 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, a second spring 211 is sleeved on the second push rod 210, and the second spring 2 The two ends of the first push rod 207 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 in a folded and contracted state to increase the passage area of ​​the sewage outlet 108.

[0030] With this solution, when the scrapers 205 move toward each other and contact the surface of the bottom frame 100, it indicates that the net box has entered the stage of cleaning dirt. 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 in a folded and contracted state, 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 cleaning 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. In one embodiment, a vibrator is sealed and connected inside the shell 212, a metal segment 2103 is provided on the second push rod 210, 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, and 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.

[0031] With this solution, when the metal segment 2103 on the second push rod 210 contacts the first conductive ring 2104 and the second conductive ring 2105, a closed loop is formed, so that the vibrator is powered on and starts to work. The vibrator vibrates under the action of electricity, achieving the effect of vibrating and cleaning the rotating rod 213 and the cleaning plate 214.

[0032] In one embodiment, the spring thruster includes a first sliding bar 300 installed on the lower cross bar 204, the upper end of the first sliding bar 300 is connected to a connecting rod 301, the lower end of the first sliding bar 300 is connected to a roller bracket 302, the roller bracket 302 is rotatably connected to a roller body 303, the first sliding bar 300 is sleeved with a third spring 304, the two ends of the third spring 304 are respectively against the lower cross bar 204 and the roller bracket 302, and in a natural state, the roller body 303 is located below the scraper 205.

[0033] By adopting such a scheme, when the roller body 303 contacts the material baffle plate 111, due to the rotation of the roller body 303 and the movement of the roller bracket 302 connected thereto, the third spring 304 sleeved on the first slide bar 300 is deformed, and a shock-driving plate with multiple protrusions is provided at the bottom of the connecting rod 301, and the shock-driving plate 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 shock-driving plate and the lower cross bar 204 is transmitted to the material baffle plate 111 through the roller body 303, so that the material baffle plate 111 is shaken while it is opened, thereby improving the discharge effect. The shaking of the material baffle plate 111 helps the material to slide more smoothly, reduces the residue of the 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.

[0034] In one embodiment, the driving unit 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, a second slide bar 406 is provided on the L-shaped plate 104, the second slide bar 406 is slidably connected to the lifting plate 200, a fourth spring 408 is sleeved on the second slide bar 406, the two ends of the fourth spring 408 are respectively abutted against the lifting plate 200 and the L-shaped plate 104, a stopper 407 is provided on the upper end of the second slide bar 406, a first driving unit 400 is installed on the lifting plate 200, the output end of the first driving unit 400 is connected to the second rotating shaft 203, a second driving unit 402 is installed on the top crossbeam 103, the output end of the second driving unit 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.

[0035] With such a 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 bar 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.

[0036] 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 urchin often lives.

[0037] The present invention divides the entire cage into two areas by arranging a vertical second mesh wall 217 in the first mesh wall 105, and installs a third mesh wall 220 that can accommodate sea urchins in one of the areas. 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 area where the sea urchins were originally located, thereby realizing position exchange and joint culture, and realizing the zoned culture 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 being beneficial to their respective growth.

[0038] When it is necessary to clean the bottom frame 100, 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 sea cucumber's feces and other dirt are scraped to the cleaning port 110 by the scraper 205. Since the top surface of the baffle plate 111 is not flush with the surface of the bottom frame 100, but a groove is formed 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 the dirt, effectively remove harmful substances in the water body, and provide a healthier growth environment for sea cucumbers and sea urchins.

[0039] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
