Description

Technical Field

[0001] This invention relates to the field of seedling cultivation and aquaculture technology, specifically to a facility for the industrialized seedling cultivation and aquaculture of sea cucumbers. Background Technology

[0002] Wild sea cucumber resources are declining sharply due to overfishing and habitat destruction, while market demand is increasing year by year. Artificial, factory-style seedling production has become a core breakthrough for the sustainable development of the industry. However, the current design of sea cucumber seedling production facilities is not fully adapted to the biological learning characteristics of larvae, and has multiple technical shortcomings, resulting in poor seedling production outcomes. First, the simulation of tidal environment lacks rationality. Existing facilities mostly rely on simple oxygenation devices or fixed flow rates, failing to replicate the periodic changes of "weak current-strong current-weak current" in the natural intertidal zone. Since larvae naturally inhabit the intertidal zone and rely on tidal currents to complete attachment, feeding and metabolism, artificial fixed flow fields cannot meet their habitual needs, directly resulting in poor larval metamorphosis attachment rates.

[0003] Secondly, the design of the attachment substrate is out of touch with the needs of the larvae. Traditional attachment substrates are mostly static structures, while in the natural environment, larvae rely on seaweed that sways with the tides to attach. Static attachment substrates cannot provide a dynamically adaptable attachment space, resulting in unstable attachment and easy detachment of larvae, which further affects their survival rate.

[0004] Third, the feeding and dispersal mechanisms are inadequate. Sea cucumber larvae burrow into the sand to feed, and existing facilities lack specialized structures for mixing and dispersing food. Food tends to clump together and has difficulty penetrating into the gaps in the sand layer, preventing the larvae from actively foraging, resulting in low feeding efficiency and uneven growth and development.

[0005] Fourth, the sand layer habitat is not adequately optimized. The existing facilities lack layered support and aeration design for the sand layer, and water flow cannot effectively penetrate the sand layer. This leads to sand layer compaction and lack of oxygen, and makes it difficult for uneaten food and feces to be discharged. After accumulation, they pollute the water body, causing suffocation or disease in larvae, resulting in poor seedling survival rate.

[0006] Fifth, the water flow intensity adjustment lacks flexibility. The water flow requirements of larvae vary significantly at different developmental stages, but existing facilities mostly have fixed water flow intensities, which cannot be dynamically adjusted according to the growth stages of the larvae. This results in larvae at different stages being in unsuitable water flow environments, ultimately leading to poor seedling stability and hindering large-scale promotion. Summary of the Invention

[0007] The purpose of this invention is to provide a facility for the industrialized breeding and cultivation of sea cucumbers to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a sea cucumber factory-scale seedling cultivation facility, comprising: a seedling box, and further comprising: a support component installed on the inner wall of the seedling box, wherein a sand layer is laid on the support component, and multiple equidistantly distributed simulated components are rotatably installed on the support component, and a piston pump is installed on one outer wall of the seedling box, wherein the inlet end of the piston pump is connected to an inlet pipe, and the outlet end of the piston pump is connected to an outlet pipe, a stirring component is installed on one inner wall of the seedling box, and a first impeller is installed at the bottom of the simulated component located in the middle of the transverse direction, and the same transmission component is installed at the bottom of every three simulated components in the longitudinal direction, and a fixed plate is installed on one outer wall of the seedling box, a rotating component is rotatably installed on one outer wall of the fixed plate, and a traction component is installed at an eccentric position on one outer wall of the rotating component, one end of the piston rod of the piston pump is rotatably connected to the traction component, and a controller and a first motor are installed on the other outer wall of the fixed plate, wherein the output shaft of the first motor is connected to one end of the rotating component.

[0009] The support assembly includes a mesh panel and a nylon screen mesh mounted on top of the mesh panel.

[0010] The nylon screen mesh is 150-200 mesh with an aperture of 75-100μm.

[0011] The simulation component includes a mounting rod, a simulated seaweed bundle sleeved on the top of the mounting rod, and a spring connecting the top of the mounting rod and the simulated seaweed bundle.

[0012] The stirring assembly includes a connecting plate, a stirring rod rotatably mounted on the outer wall of the connecting plate, and a second impeller mounted on one end of the stirring rod.

[0013] The transmission assembly includes synchronous pulleys mounted on the bottom of the three simulation components and synchronous belts that drive the transmission on the three synchronous pulleys.

[0014] The rotating assembly includes a rotating rod, a turntable mounted at one end of the rotating rod, and a conductive slip ring mounted on the outer wall of the rotating rod.

[0015] The traction assembly includes a housing, a threaded rod rotatably mounted on the inner wall of one side of the housing, a second motor mounted on the outer wall of one side of the housing, and a moving block screwed onto the threaded rod.

[0016] One end of the piston rod of the piston pump is rotatably connected to the outer wall of the moving block.

[0017] The second motor is connected to the inner slip ring rotor of the conductive slip ring via a wire.

[0018] Compared with the prior art, the beneficial effects of the present invention are: This invention discloses a factory-scale sea cucumber seedling cultivation facility. Through the coordinated operation of multiple components, it precisely simulates the tidal environment and micro-movement state of seagrass, the natural habitat of sea cucumbers, providing dynamically adapted attachment space for larvae and effectively improving their metamorphic attachment effect. The water circulation design loosens the sand layer and replenishes dissolved oxygen in the water, preventing sand layer compaction and oxygen deficiency, perfectly adapting to the burrowing habits of larvae. The stirring component can agitate the feed into a uniform suspension, which permeates into the gaps in the sand layer with the water flow, ensuring the feeding needs of burrowing larvae. The water flow intensity can be flexibly adjusted to adapt to the survival needs of larvae at different growth stages. The overall structure is tightly coordinated and operates stably, reducing water pollution and mechanical damage to larvae, significantly improving seedling survival rate and cultivation efficiency, and providing reliable technical support for large-scale factory-scale sea cucumber cultivation.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-10 This invention provides a sea cucumber factory-scale seedling cultivation facility, comprising: a seedling box 1, and a support component 2 installed on the inner wall of the seedling box 1. A sand layer 3 is laid on the support component 2. Multiple equally spaced simulated components 4 are rotatably mounted on the support component 2. A piston pump 5 is installed on one outer wall of the seedling box 1, with an inlet pipe 6 connected to the inlet end of the piston pump 5 and an outlet pipe 7 connected to the outlet end of the piston pump 5. A stirring component 8 is installed on one inner wall of the seedling box 1, and the simulated components 4 are positioned at the bottom of the simulated components 4 in the horizontal middle position. The first impeller 9 is installed in the part, and the same transmission component 10 is installed at the bottom of every three simulation components 4 in the longitudinal direction. A fixed plate 11 is installed on one side of the outer wall of the seedling box 1. A rotating component 12 is rotatably installed on one side of the outer wall of the fixed plate 11. A traction component 13 is installed at an eccentric position on one side of the outer wall of the rotating component 12. One end of the piston rod of the piston pump 5 is rotatably connected to the traction component 13. A controller 15 and a first motor 14 are installed on the other side of the outer wall of the fixed plate 11. The output shaft of the first motor 14 is connected to one end of the rotating component 12.

[0023] It should be noted that: after the first motor 14 starts, it runs at low speed, driving the rotating component 12 to rotate; the rotating component 12 drives the traction component 13 to move through the eccentric structure, and the traction component 13 converts the circular motion into the reciprocating linear motion of the piston rod of the piston pump 5; the piston pump 5 draws water from the upper part of the seedling box 1 through the water inlet pipe 6, and then delivers it to the bottom of the seedling box 1 through the water outlet pipe 7, and the water surges upward to form a simulated tidal flow; the upward surging water flow acts on the first impeller 9 at the bottom of the simulation component 4 in the horizontal middle position, driving the simulation component 4 to rotate; the simulation component 4 transmits power to the two longitudinally adjacent simulation components 4 through the transmission component 10, realizing the synchronous rotation of multiple sets of simulation components 4, and under the action of the water flow, the simulation components 4... The pump 5 swings, and at the same time, the water flow from the piston pump 5 drives the stirring component 8 on the inner wall of the seedling box 1 to rotate. The powder sprinkled in during feeding is stirred into a suspension by the stirring component 8 and pumped to the bottom and surges upward with the water flow. This not only loosens the sand layer 3 on the supporting component 2 through the water flow, but also causes the powder to spread evenly into the sand layer 3. The first impeller 9 weakens the water flow force and disperses the water flow so as not to wash away the fine sand layer. This can maintain the stability of the seedling's sand-burrowing channel and allow all the sand-burrowing larvae to feed. In addition, the traction component 13 can adjust the connection position of the piston rod of the piston pump 5, change its stroke, and thus adjust the water flow intensity to adapt to the needs of larvae at different growth stages. Finally, by simulating the natural ecology through "tidal water flow + swinging simulation component", the success rate of metamorphosis attachment of larvae is improved.

[0024] In a preferred embodiment, the support component 2 includes a mesh plate 201 and a nylon screen mesh 202 mounted on top of the mesh plate 201.

[0025] It should be noted that: the mesh plate 201 provides rigid support for the upper structure, bearing the weight of the sand layer 3 and the simulation component 4, and preventing the sand layer 3 from collapsing; the nylon sieve mesh 202 on the top of the mesh plate 201 plays the role of "blocking sand and allowing flow" - allowing the water flow delivered by the piston pump 5 and the mixed bait particles to pass through, ensuring that the water flow can surge upward over the sand layer 3 and the bait can penetrate into the gaps in the sand layer, while preventing sand particles in the sand layer 3 from leaking into the area below the mesh plate 201, creating a "stable sand-diving habitat + under-sand feeding" environment for the larvae.

[0026] In a preferred embodiment, the nylon screen 202 has a mesh size of 150-200 and an aperture of 75-100 μm.

[0027] It should be noted that the aperture size is just right for sea cucumber larvae bait (particle size 10-75μm), ensuring that the bait suspension after stirring can smoothly penetrate the sieve 202 and enter the sand layer 3; at the same time, its aperture size is smaller than the minimum particle size of fine sand in the sand layer 3 (100μm), which can effectively trap fine sand.

[0028] In a preferred embodiment, the simulation component 4 includes a mounting rod 401, a simulated seaweed bundle 402 sleeved on the top of the mounting rod 401, and a spring 403 connecting the top of the mounting rod 401 and the simulated seaweed bundle 402.

[0029] It should be noted that: the mounting rod 401, as the core support component, receives the power transmitted by the first impeller 9 or the transmission component 10 and drives the simulated seaweed bundle 402 to rotate; the simulated seaweed bundle 402 simulates the shape of natural seaweed and swings with the mounting rod 401 to form a dynamic attachment space, allowing the larvae to easily attach in the tidal current; the spring 403 between the mounting rod 401 and the simulated seaweed bundle 402 plays a buffering role - when the water flow intensity fluctuates or the rotation speed of the mounting rod 401 changes, the spring 403 can buffer the impact of the water flow, making the swing of the simulated seaweed bundle 402 more closely match the state of natural seaweed moving slightly with the tide, providing a dynamic attachment space for the larvae.

[0030] In a preferred embodiment, the stirring assembly 8 includes a connecting plate 801, a stirring rod 802 rotatably mounted on the outer wall of the connecting plate 801, and a second impeller 803 mounted on one end of the stirring rod 802.

[0031] It should be noted here that when the piston pump 5 draws water through the inlet pipe 6, the water flow will impact the second impeller 803 at one end of the stirring rod 802, causing the second impeller 803 to rotate synchronously with the stirring rod 802. The rotating stirring rod 802 will disperse the powder sprinkled into the water, forming a uniform bait suspension, which will prevent the powder from clumping and being unable to penetrate the sand layer 3 with the water flow, ensuring that the larvae can feed evenly in the sand layer 3, and at the same time reducing the risk of clumped powder polluting the water quality.

[0032] In a preferred embodiment, the transmission assembly 10 includes synchronous pulleys 1001 mounted on the bottom of the three simulation assemblies 4 and synchronous belts 1002 connected to the three synchronous pulleys 1001.

[0033] It should be noted that: a synchronous wheel 1001 is installed at the bottom of every three longitudinal simulation components 4, and the three synchronous wheels 1001 are connected by a synchronous belt 1002; when the middle simulation component 4 is driven to rotate by the first impeller 9, the synchronous wheel 1001 at its bottom will drive the synchronous wheels 1001 of the simulation components 4 on both sides to rotate synchronously through the synchronous belt 1002, thereby realizing the synchronous swaying of the simulated seaweed bundles 402 of the three simulation components 4; this design avoids uneven local water flow / attachment environment caused by the rotation of a single set of simulation components 4, and ensures that the larvae in all areas of the seedling box 1 can come into contact with the swaying seaweed and uniform water flow.

[0034] In a preferred embodiment, the rotating assembly 12 includes a rotating rod 1201, a turntable 1202 mounted on one end of the rotating rod 1201, and a conductive slip ring 1203 mounted on the outer wall of the rotating rod 1201.

[0035] It should be noted here that: the output shaft of the first motor 14 is connected to the rotating rod 1201, driving the rotating rod 1201 and the turntable 1202 at one end to rotate synchronously; the turntable 1202 has an eccentric structure, and the traction component 13 installed at its eccentric position will generate a lateral reciprocating motion when it rotates with the turntable 1202, providing power to the piston rod of the piston pump 5; the conductive slip ring 1203 on the outer wall of the rotating rod 1201 solves the problem of "power supply in rotation state" - the slip ring rotor of the conductive slip ring 1203 rotates with the rotating rod 1201, and the stator is fixed on the fixed plate 11. Through the sliding contact between the rotor and the stator, the second motor 1303 in the traction component 13 is continuously powered, avoiding the wires from getting tangled and affecting the rotation.

[0036] In a preferred embodiment, the traction assembly 13 includes a housing 1301, a threaded rod 1302 rotatably mounted on the inner wall of one side of the housing 1301, a second motor 1303 mounted on the outer wall of one side of the housing 1301, and a moving block 1304 screwed onto the threaded rod 1302.

[0037] It should be noted that when the water flow needs to be adjusted, the second motor 1303 starts and drives the threaded rod 1302 to rotate inside the housing 1301. The threaded rod 1302 and the moving block 1304 are screwed together. When the threaded rod 1302 rotates, it drives the moving block 1304 to move along the axial direction of the threaded rod 1302. The moving block 1304 is rotatably connected to the piston rod of the piston pump 5. Its position change will change the reciprocating stroke of the piston rod of the piston pump 5. When the stroke increases, the single pumping volume of the piston pump 5 increases, and the water flow intensity is enhanced to suit segmented larvae. When the stroke decreases, the pumping volume decreases, and the water flow intensity is reduced to suit trochlear larvae, thus achieving the convenience of "adjusting the flow without replacing the pump body".

[0038] In a preferred embodiment, one end of the piston rod of the piston pump 5 is rotatably connected to the outer wall of the movable block 1304.

[0039] It should be noted that when the moving block 1304 moves in a circular motion with the turntable 1202 of the rotating assembly 12, the circular motion can be smoothly converted into the reciprocating linear motion of the piston rod of the piston pump 5 through the rotational connection, thus avoiding jamming or component wear caused by rigid connection.

[0040] In a preferred embodiment, the second motor 1303 is connected to the inner slip ring rotor of the conductive slip ring 1203 via a wire.

[0041] It should be noted that the second motor 1303 is mounted on the traction assembly 13 that rotates with the turntable 1202. If it is powered directly by a fixed wire, the wire will become tangled and break as the turntable 1202 rotates. The second motor 1303 is connected to the slip ring rotor of the conductive slip ring 1203 by a wire. The slip ring rotor rotates synchronously with the rotating rod 1201, while the stator is connected to an external power source. The sliding contact between the rotor and the stator is used to achieve "continuous power supply in rotational state", which ensures that the second motor 1303 can stably drive the threaded rod 1302, adjust the piston rod stroke of the piston pump 5, and ensure the long-term reliability of the water flow regulation function.

[0042] Working principle: This device is based on "simulating natural tides + dynamic habitat + precise adaptation to the needs of larvae". Through the mechanical linkage of multiple components and environmental control, it realizes the adaptation of the entire process of sea cucumber seedling cultivation. The controller 15 starts the first motor 14 to rotate at low speed. The output shaft of the first motor 14 drives the rotating rod 1201 of the rotating component 12 to rotate. The rotating rod 1201 synchronously drives the turntable 1202 at one end to make a circular motion. Since the traction component 13 is installed at the eccentric position of the turntable 1202, when the turntable 1202 rotates, it will drive the traction component 13 to make a "circular → reciprocating" conversion motion.

[0043] The moving block 1304 of the traction component 13 is rotatably connected to one end of the piston rod of the piston pump 5. The reciprocating motion of the moving block 1304 directly drives the piston rod of the piston pump 5 to perform linear reciprocating motion. The piston pump 5 draws water from the upper part of the seedling box 1 through the water inlet pipe 6, and then transports the water to the bottom of the seedling box 1 through the water outlet pipe 7. The water flows upward from the bottom, forming an upward water flow that simulates the natural intertidal "high tide". When the piston rod of the piston pump 5 returns to its original position, the water in the seedling box 1 naturally falls back, completing the "low tide" cycle and replicating the tidal changes as a whole.

[0044] The upward-flowing water impacts the first impeller 9 at the bottom of the simulation component 4 at the middle horizontal position. The kinetic energy of the water is converted into the rotational kinetic energy of the first impeller 9, which in turn drives the corresponding mounting rod 401 of the simulation component 4 to rotate.

[0045] When the mounting rod 401 rotates, the synchronous wheel 1001 at its bottom drives the synchronous wheels 1001 of the two longitudinally adjacent simulation components 4 to rotate synchronously through the synchronous belt 1002, ultimately achieving synchronous rotation of "every three simulation components 4 in the longitudinal direction"; when the mounting rod 401 of the simulation component 4 rotates, the simulated seaweed bundle 402 at the top swings with the mounting rod 401, and at the same time, the spring 403 between the mounting rod 401 and the simulated seaweed bundle 402 can buffer the impact of water flow, so that the swing of the simulated seaweed bundle 402 is more in line with the natural seaweed's slight movement with the tide, providing dynamic attachment space for the larvae.

[0046] When the piston pump 5 draws water through the inlet pipe 6, the water flow will impact the second impeller 803 of the stirring assembly 8. The second impeller 803 drives the stirring rod 802 to rotate around the connecting plate 801. At this time, the ultrafine powder (suitable for sea cucumber larvae to feed on) sprinkled into the seedling box 1 will be stirred into a uniform suspension by the rotating stirring rod 802 to avoid the powder from clumping.

[0047] The suspension containing feed is transported to the bottom of the nursery box 1 by the water flow of the piston pump 5. The upward water flow penetrates the support component 2. The mesh plate 201 of the support component 2 provides rigid support. The 150-200 mesh nylon screen 202 (pore size 75-100μm) at the top can prevent sand particles from leaking into the sand layer 3, while allowing the feed suspension and water flow to smoothly penetrate into the sand layer 3. The water flow will both loosen the fine sand in the sand layer 3 (to avoid compaction and adapt to the burrowing habits of larvae) and carry the feed to spread evenly to the gaps in the sand layer 3, allowing the burrowing larvae to passively feed through the tentacle crown.

[0048] Water flow adjustment (adapting to larval stage): When it is necessary to adjust the water flow intensity according to the larval growth stage (e.g., trochophore larva → somatic larva), the second motor 1303 of the traction component 13 is activated; the second motor 1303 drives the threaded rod 1302 to rotate within the housing 1301 through a wire (connected to the inner slip ring rotor of the conductive slip ring 1203 to avoid wire entanglement during rotation). The threaded rod 1302 is screwed into the moving block 1304, driving the moving block 1304 to move axially along the threaded rod 1302; the change in the position of the moving block 1304 will change the reciprocating stroke of the piston rod of the piston pump 5 (increased stroke → increased pumping volume → stronger water flow, and vice versa), thereby achieving adjustment of the flow field intensity.

[0049] 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 implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
