[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0016] 1. This utility model provides a sea urchin seedling cultivation device, which employs a combination of a cultivation mechanism, a water exchange device, a base, a water inlet pump, a funnel, a water pump, an oxygenation device, a fixed plate, a motor, a drive wheel, a transmission belt, a follower wheel, a lever, a scraper, an oxygenation pipe, a corrugated oxygen pipe, a shell, a bracket, a fixed frame, supplemental lighting, a limiting block, and a compartmentalized bracket. The base serves as the foundation of the entire device. The water inlet pump provides water to the entire device, and the water pump extracts water from the device to meet the water exchange requirements for sea urchin cultivation. When the water pump draws water, debris inside the water body is collected through the funnel and then pumped away along with the water. The oxygenation device divides the base and the shell into two spaces. The width of the oxygenation device is smaller than the opening width of the base, making it less likely for debris cleaned into the base by the oxygenation device to return to the shell. The bracket... By fixing the supplemental light at a suitable height and angle, it can provide illumination for sea urchin species that require additional lighting. The combination of the compartmentalized bracket and the fixed frame facilitates the placement of the storage mechanism. The fixed plate is fixed inside the base, with gaps reserved at both ends. The motor drives the drive wheel to rotate, which moves the transmission belt. The lever on the top of the transmission belt causes the corrugated scraper to reciprocate. The corrugated oxygen tube extends and retracts with the movement of the scraper. The oxygen supply tube is supplied with oxygen by connecting the corrugated oxygen tube to the oxygen pump, allowing the oxygen supply tube to evenly oxygenate the sea urchins inside the storage mechanism. When the scraper moves, it also moves the food residue and sea urchin feces accumulated on the top of the fixed plate, causing them to fall into the base through the gaps between the fixed plate and the base. The special shape of the scraper helps the debris enter the base, improving the adaptability of the device.

[0017] 2. This utility model provides a sea urchin seedling cultivation device, which employs a storage mechanism, fixing frame, handle, fixing bolts, mesh frame, top cover device, top cover, ventilation hole, concealed hinge, threaded hole, partition, water inlet net, and feed filter. By placing multiple fixing frames inside the compartmentalized support and placing sea urchins inside the mesh frame, the density of sea urchin aggregation can be effectively planned, and the approximate number of sea urchins can be easily counted later. The partition provides attachment points for sea urchins according to their living habits, and the water inlet net allows water to enter the interior of the mesh frame, allowing food to be placed inside. Placed inside the net frame, food scraps and excrement from sea urchins after feeding will fall into the aquaculture facility through the opening of the feed filter. Since the mesh size of the feed filter is smaller than that of the sea urchins, no sea urchins will fall into the aquaculture facility. When it is necessary to transfer sea urchins later, the top cover can be removed, one end of the top cover can be inserted into the handle, and the threaded hole can be fixed with fixing bolts. The curved design of the side of the top cover will help the top cover to be inserted into the handle. At this time, the storage mechanism is a relatively closed box, which can facilitate the transportation of sea urchins and improve the adaptability of the device. Attached Figure Description

[0025] The present invention will be further described in detail below with reference to embodiments:

[0026] Example 1

[0027] like Figure 1-6As shown, this utility model provides a sea urchin seedling cultivation device, including a cultivation mechanism 1. The cultivation mechanism 1 has a storage mechanism 2 inside. The cultivation mechanism 1 includes a water exchange device 11. An oxygenation device 12 is installed at the top of the inner side of the water exchange device 11. A shell 13 is fixedly connected to the top surface of the water exchange device 11. A support 14 is fixedly connected to the side of the shell 13. A supplementary light 16 is movably connected to the top of the inner side of the support 14. A limit block 17 is fixedly connected to the bottom of the inner side of the shell 13. A [missing information - likely a device name] is fixedly connected to the middle of the inner side of the shell 13. The compartmentalized support 18 has a fixed frame 15 fixedly connected to the bottom of its inner side. There are multiple fixed frames 15, which are evenly distributed inside the compartmentalized support 18. The water changing device 11 includes a base 111. The input end of the base 111 is fixedly connected to a water inlet pump 112. The outer shell 13 is fixedly connected to the top surface of the base 111. The input end of the base 111 is fixedly connected to the water inlet pump 112. The output end of the base 111 is fixedly connected to a funnel 113. The output end of the funnel 113 is fixedly connected to a water pump 114.

[0028] In this embodiment, the base 111 serves as the base of the entire device. The water inlet pump 112 provides water to the entire device, and the water pump 114 extracts water from the device to meet the water exchange requirements for sea urchin farming. When the water pump 114 pumps water, debris inside the water body will be collected through the funnel 113 and pumped away with the water pump 114. The oxygenation device 12 can divide the base 111 and the outer shell 13 into two spaces. The width of the oxygenation device 12 is smaller than the opening width of the base 111, so that the debris cleaned into the base 111 by the oxygenation device 12 is not easy to return to the interior of the outer shell 13. The bracket 14 fixes the supplementary light 16 at a suitable height. The supplementary light 16 can be fixed at a suitable angle to provide supplementary lighting for sea urchin varieties that need supplementary lighting. The combination of the compartment bracket 18 and the fixing frame 15 facilitates the placement of the storage mechanism 2.

[0029] Example 2

[0030] like Figure 1-6As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the oxygen supplementation device 12 includes a fixing plate 121, which is fixedly connected to the top of the inner side of the base 111. A motor 122 is fixedly connected to the inner bottom surface of the fixing plate 121. A drive wheel 123 is fixedly connected to the output end of the motor 122. The drive wheel 123 is rotatably connected to the inside of the top surface of the fixing plate 121. A transmission belt 124 is movably connected to the outer surface of the drive wheel 123. Another transmission belt 124 is located inside the transmission belt 124. A follower wheel 125 is movably connected to the end of the fixed plate 121. The follower wheel 125 is rotatably connected to the other end of the top surface of the fixed plate 121. A lever 126 is fixedly connected to the top surface of the transmission belt 124. A scraper 127 is movably connected to the outer surface of the lever 126. An oxygen supply pipe 128 is movably connected to the inside of the top surface of the scraper 127. A corrugated oxygen pipe 129 is fixedly connected to the input end of the oxygen supply pipe 128. One end of the corrugated oxygen pipe 129 is fixedly connected to the inside of the side of the outer shell 13. A limiting block 17 is movably connected to the side of the scraper 127.

[0031] In this embodiment, the fixed plate 121 is fixed inside the base 111 with gaps at both ends. The motor 122 drives the drive wheel 123 to rotate, which moves the transmission belt 124. The lever 126 on the top surface of the transmission belt 124 causes the corrugated scraper 127 to reciprocate. The corrugated oxygen pipe 129 extends and retracts with the movement of the scraper 127. The oxygen pump connects to the corrugated oxygen pipe 129 to provide oxygen to the oxygen supply pipe 128, so that the oxygen supply pipe 128 can evenly oxygenate the sea urchins inside the storage mechanism 2. When the scraper 127 moves, it also moves the food residue and sea urchin feces accumulated on the top surface of the fixed plate 121, which fall into the interior of the base 111 through the gap between the fixed plate 121 and the base 111. The special shape of the scraper 127 helps the debris enter the interior of the base 111.

[0032] Example 3

[0033] like Figure 1-6As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the storage mechanism 2 includes a fixed frame 21, which is movably connected inside the compartment support 18. A fixed frame 15 is tightly attached to the bottom surface of the fixed frame 21. A handle 22 is fixedly connected to the top surface of the fixed frame 21. A top cover device 25 is movably connected inside the handle 22. A fixing bolt 23 is movably connected inside the top surface of the handle 22. A mesh frame 24 is fixedly connected inside the fixed frame 21. A partition 26 is fixedly connected inside the mesh frame 24. A partition plate 26 is fixedly connected inside the side of the mesh frame 24. There is a water inlet screen 27, and a material leakage filter screen 28 is fixedly connected to the bottom surface of the screen frame 24. The top cover device 25 includes a top cover 251, which is movably connected to the inside of the handle 22. A threaded hole 254 is fixedly connected to one end of the top surface of the top cover 251. One end of the fixing bolt 23 is threadedly connected to the inside of the threaded hole 254. A vent hole 252 is opened on the top surface of the top cover 251. A hidden hinge 253 is movably connected to the inside of the side of the vent hole 252. There are two vent holes 252. Another vent hole 252 is movably connected to the other end of the hidden hinge 253.

[0034] In this embodiment, by placing multiple fixing brackets 21 inside the compartment support 18 and placing sea urchins inside the mesh frame 24, the density of sea urchin aggregation can be effectively planned, and it is convenient to count the approximate number of sea urchins later. The partition 26 can provide attachment points for sea urchins according to their living habits. The water inlet net 27 allows water to enter the inside of the mesh frame 24. Food is placed inside the mesh frame 24. Food residue and excrement after the sea urchins have eaten will fall into the aquaculture facility 1 through the opening of the feed filter 28. Since the mesh size of the feed filter 28 is smaller than that of the sea urchins, no sea urchins will fall into the aquaculture facility 1. When it is necessary to transfer sea urchins later, the top cover 251 can be removed, one end of the top cover 251 can be inserted into the handle 22, and the threaded hole 254 can be fixed by the fixing bolt 23. The side arc design of the top cover 251 will help the top cover 251 to be inserted into the handle 22. At this time, the storage facility 2 is a relatively closed box, which can facilitate the transportation of sea urchins.

[0035] The working principle of this sea urchin seedling cultivation device will be explained in detail below.

[0036] like Figure 1-6As shown, by placing multiple fixing frames 21 inside the compartmentalized support 18 and placing sea urchins inside the net frame 24, the density of sea urchin aggregation can be effectively planned, and it is also convenient to count the approximate number of sea urchins later. The partition 26 can provide attachment points for sea urchins according to their living habits. The water inlet net 27 allows water to enter the inside of the net frame 24. Food is placed inside the net frame 24. Food residue and excrement after the sea urchins have eaten will fall into the aquaculture facility 1 through the opening of the feed strainer 28. Since the mesh size of the feed strainer 28 is smaller than that of the sea urchins, no sea urchins will fall into the aquaculture facility 1. The fixing plate 121 is fixed inside the base 111, with gaps reserved at both ends. The motor 122 drives the drive wheel 123 to rotate, which moves the transmission belt 124. The lever 126 on the top surface of the transmission belt 124 causes the corrugated scraper 127 to reciprocate. The corrugated oxygen pipe 129 extends and retracts with the movement of the scraper 127. The oxygen supply pipe 128 is supplied by the oxygen pump connected to the corrugated oxygen pipe 129, so that the oxygen supply pipe 128 can evenly supply oxygen to the sea urchins inside the storage mechanism 2. When the scraper 127 moves, it also moves the food residue and sea urchin feces accumulated on the top surface of the fixing plate 121. The gap between 121 and base 111 allows debris to fall into the interior of base 111. The special shape of scraper 127 helps debris enter the interior of base 111. Water pump 112 provides water to the entire device and pumps water from inside the device through pump 114 to meet the water change requirements of sea urchin farming. When pump 114 pumps water, debris inside the water body will collect through funnel 113 and be pumped away along with the water by pump 114. Oxygenation device 12 can separate base 111 and outer shell 13 into two spaces. The width of oxygenation device 12 is smaller than the opening width of base 111, allowing the oxygenation device to pass through... 12. Dirt swept into the base 111 is not easily returned to the inside of the outer shell 13. The bracket 14 fixes the supplementary light 16 at a suitable height. The supplementary light 16 can be fixed at a suitable angle to provide supplementary lighting for sea urchin varieties that need supplementary lighting. When it is necessary to transfer sea urchins later, the top cover 251 can be taken out, one end of the top cover 251 can be inserted into the handle 22, and the threaded hole 254 can be fixed by the fixing bolt 23. The side arc design of the top cover 251 will help the top cover 251 to be inserted into the handle 22. At this time, the storage mechanism 2 is a relatively closed box, which can facilitate the transportation of sea urchins.

[0037] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
