Description

Technical Field

[0001] This utility model relates to the field of sea cucumber cleaning technology, and in particular to a biomimetic abdominal cavity deodorization and cleaning device for sea cucumbers. Background Technology

[0002] As a precious seafood, sea cucumber requires meticulous cleaning during processing, a crucial step that is currently largely done manually. Workers must individually cut open each sea cucumber, then use their fingers to pry, dig, rub, and knead it inside its abdominal cavity, followed by rinsing with water. This method is not only extremely inefficient and labor-intensive, but the cleaning quality also relies entirely on individual experience, resulting in inconsistent quality and failing to meet the hygiene and efficiency requirements of large-scale production.

[0003] While some automated or semi-automated sea cucumber cleaning equipment exists on the market, their technical solutions often have inherent flaws, making it difficult to achieve high-quality, biomimetic cleaning of the sea cucumber's abdominal cavity. For example, most equipment uses drum or basket cleaning, where the sea cucumber tumbles and rolls within the container, making it impossible to target and clean the abdominal cavity of individual sea cucumbers. Some existing equipment is specifically designed for cleaning the abdominal cavity, but its cleaning methods, such as ordinary spraying and bubble agitation, primarily focus on the sea cucumber's surface. The water flow cannot penetrate deep into the folds of the abdominal cavity, nor can it effectively separate the internal organs connected to the inner wall via mesentery. The mucus and fine sand on the inner wall of the sea cucumber cannot be removed by simple rinsing, often leaving residue after cleaning, affecting the product's taste and quality. Utility Model Content

[0004] The purpose of this utility model is to provide a biomimetic abdominal cavity deodorization and cleaning device for sea cucumbers, so as to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: This utility model provides a biomimetic abdominal cavity deodorization and cleaning device for sea cucumbers, comprising: The workbench is equipped with at least one cleaning station, which is provided with a docking nozzle for water output and a transmission component for rotational power output. The clamping base is detachably positioned and clamped on the cleaning station. The clamping base is provided with a drive wheel and several driven gears. The several driven gears are synchronously driven, and one of the driven gears is connected to the drive wheel. The bottom of the clamping base is provided with a water channel interface and a drive interface. The water channel interface is provided with a plug that seals with the docking nozzle. The drive wheel is provided with a drive shaft. The end of the drive shaft extends to the drive interface for meshing with the transmission components of the cleaning station. At least one insert is mounted on the clamping base via a roller bearing. The bottom end of the insert extends through the roller bearing into the clamping base and is externally fixed with a toothed ring. The toothed ring meshes with the driven gear for transmission. The insert has a hollow cavity, and the bottom end of the hollow cavity is provided with a rotary joint. The rotary joint is connected to the insertion nozzle via a connecting pipe. The outer surface of the insert has raised spiral guide ribs and multiple sets of radial injection holes.

[0006] This invention utilizes a rotating insert and a fixed sea cucumber. The spiral guide ribs on the insert surface effectively knead, comb, and shear within the sea cucumber's abdominal cavity, mimicking the action of manual finger cleaning. Combined with water jetting, it effectively removes viscera, mesentery, and sediment, solving the problem of inadequate cleaning by traditional equipment. The modular clamping base design enables offline unloading and online cleaning. Workers can pre-process and clamp the sea cucumbers onto the base outside the production line, followed by rapid automated cleaning, reducing equipment waiting time and making it suitable for continuous production lines.

[0007] As a further improvement of this utility model: the cleaning station is provided with a lifting plate and a liftable elastic pressing mechanism set on the lifting plate, which is used to gently press down on the outer wall of the sea cucumber sleeved on the insertion column during cleaning.

[0008] This improved design prevents the sea cucumber from rotating completely synchronously with the insertion post, ensuring that the guide ribs and water flow on the insertion post can generate relative motion and shear force with the inner wall of the sea cucumber's abdominal cavity.

[0009] As a further improvement of this invention: the lower surface of the insertion post is provided with at least two guide channels, which start from the lower surface of the insertion post and extend towards its bottom. During the cleaning process, the detached impurities fall naturally to the bottom of the insertion post under the influence of gravity, water flow impact, and the pushing force of the guide ribs. The guide channels direct these substances and allow them to be smoothly discharged from the incision at the bottom of the sea cucumber. This improved design provides a low-resistance outflow path for the washed-off viscera, mud, and other impurities, preventing them from accumulating or clogging at the bottom of the insertion post.

[0010] As a further improvement of this utility model, the spiral guide ribs are provided with a frosted surface at their outermost radial end. This improvement generates greater static and sliding friction between the guide ribs and the soft, moist inner wall of the sea cucumber, enhancing the kneading effect. The micro-cutting action formed by the frosted surface can more effectively scrape off tightly adhered mucus and fine mud.

[0011] As a further improvement of this utility model: the radial height of the spiral guide rib varies along its axial direction, with the radial height of its central region being greater than that of its two end regions. When the insert rotates, the central protrusion exerts stronger kneading and shearing forces on the middle section of the sea cucumber's abdominal cavity, simulating the action of rubbing the middle section of the sea cucumber with fingers during manual cleaning.

[0012] As a further improvement of this utility model: the cross-section of the spiral guide rib is asymmetrical, with different radii of curvature or inclination angles on its two sides. When the insert rotates at a constant speed, the asymmetrical contour will generate a periodic, left-right asymmetrical radial force on the inner wall of the sea cucumber. This periodically changing force will force the soft sea cucumber body wall to produce a slight, passive left-right sway, simulating manual cleaning, where the sea cucumber is held and shaken back and forth, using inertia to shake off the loosened internal organ fragments.

[0013] As a further improvement of this utility model: the top of the insertion post is provided with an annular spray hole, which is connected to the hollow cavity to form an umbrella-shaped water curtain sprayed outward and downward towards the insertion post. The umbrella-shaped water curtain formed by the annular spray hole washes from top to bottom, rinsing the top before the water flows into the deep abdominal cavity, and evenly wetting the entire inner wall of the abdominal cavity, preparing for subsequent deep cleaning and eliminating cleaning dead spots.

[0014] As a further improvement of this invention: each group of radial jet holes is arranged in a circumferential array, and the jetting angle of each radial jet hole unit in the same group is different. Water flows out simultaneously from jet holes at different angles, forming a complex three-dimensional flow field within the fixed abdominal cavity of the sea cucumber, impacting and stripping impurities from all directions. Water flows at different angles collide and reflect each other within the abdominal cavity, forming a highly turbulent, thorough cleaning network.

[0015] As a further improvement of this utility model: the drive wheel and the driven gear are connected by a synchronous belt. Synchronous belt drive is flexible and can absorb vibration and impact; compared to pure gear drive, the equipment operates more smoothly and with reduced noise.

[0016] As a further improvement of this invention, the cleaning equipment also includes a pulse water flow generator electrically connected to the control unit. The pulse water flow generator is disposed within the water path inside the worktable and is used to modulate the water flow delivered to the radial jet orifice into a periodically changing pulse water flow. The pulse water flow instantly generates a peak pressure far exceeding that of a constant water flow. This periodic shock wave has a strong physical tearing and peeling effect on tightly attached viscera and mesentery. Attached Figure Description

[0023] Reference Figures 1 to 3 The following are several embodiments of a biomimetic abdominal cavity deodorization and cleaning device for sea cucumbers according to this utility model.

[0024] An embodiment of this utility model provides a biomimetic abdominal cavity deodorization and cleaning device for sea cucumbers, such as... Figures 1-3 As shown, it includes: The workbench 100 is provided with at least one cleaning station 110, wherein the cleaning station 110 is provided with a docking nozzle 111 for water output and a transmission component 112 for rotational power output. The clamping base 200 is detachably positioned and clamped on the cleaning station 110. The clamping base 200 is provided with a drive wheel 210 and several driven gears 220. The several driven gears 220 are synchronously driven, and one of the driven gears 220 is connected to the drive wheel 210. The bottom of the clamping base 200 is provided with a water channel interface and a drive interface. The water channel interface is provided with a plug 230 that is sealed and connected to the docking nozzle 111. The drive wheel 210 is provided with a drive shaft 240. The end of the drive shaft 240 extends to the drive interface for meshing and driving with the transmission component 112 of the cleaning station 110. At least one insert post 300 is mounted on the clamping base 200 via a roller bearing 310. The bottom end of the insert post 300 extends into the clamping base 200 through the roller bearing 310 and is externally fixed with a toothed ring 320. The toothed ring 320 is meshed with the driven gear 220 for transmission. The insert post 300 is provided with a hollow cavity 330. The bottom end of the hollow cavity 330 is provided with a rotary joint 340. The rotary joint 340 is connected to the insertion nozzle 230 via a connecting pipe 350. The outer surface of the insert post 300 is provided with raised spiral guide ribs 360 and multiple sets of radial injection holes 370 are opened on the outer surface.

[0025] In this embodiment, the transmission component is the driving gear at the output shaft end of the drive motor, and the end of the transmission shaft at the drive interface is provided with a matching internal gear, which meshes with the drive motor for transmission. The rotary joint adopts an axial end-face mechanical seal, with the stationary ring fixed to the insertion nozzle and / or connecting pipe, and the rotating ring rotating with the insertion post to ensure continuous water flow and no leakage during rotation. Several driven gears can be synchronously driven through a common idler pulley or timing belt.

[0026] In this embodiment, workers first place the head-and-tail-removed sea cucumbers onto the inserts of the clamping base on the production line. Then, the clamping base, filled with sea cucumbers, is moved to the workbench and positioned at the cleaning station. Those skilled in the art will understand that positioning and clamping can be achieved using existing technologies such as positioning pins and holes or guide rails and grooves, which will not be elaborated upon here. When the clamping base is in position, its drive shaft automatically engages with the transmission components of the workbench (e.g., through end face teeth, splines, etc.), and its water channel connector's insertion nozzle and the workbench's mating nozzle are sealed together by a sealing ring to ensure water flow. The elastic pressing mechanism on the workbench descends under the drive of a cylinder or motor, gently and stably pressing down on the outer wall of the sea cucumber, fixing it relatively and reducing its rotation with the inserts.

[0027] At this point, the power system of the worktable rotates the drive wheel through transmission components and a drive shaft, which in turn drives all driven gears to rotate synchronously through a gear (or synchronous belt) transmission system. It should be noted that the power system and meshing transmission method of the worktable utilize existing technologies to achieve the rotation of the drive wheel, such as motor drive and automatic gear meshing. The driven gear meshes with a toothed ring fixed on the insert, driving the insert to rotate smoothly under the support of roller bearings. Simultaneously, water (which may be mixed with a deodorizing agent) enters the hollow cavity of the insert through the docking nozzle, insert nozzle, connecting pipe, and rotary joint. The water is ejected from multiple sets of radial spray holes on the surface of the insert, directly impacting the inner wall of the cavity.

[0028] As the insertion column rotates, the spiral guide ribs on its surface create relative motion with the fixed inner wall of the sea cucumber, continuously rubbing and scraping to separate the viscera from the mucous membrane. The separated impurities, driven by their own gravity, water flow, and the spiral guide ribs, move towards the bottom of the insertion column. Guided by the guide groove at the bottom of the insertion column, the impurities are smoothly discharged from the bottom cut of the sea cucumber and enter the wastewater discharge system of the workbench, which is existing technology. After cleaning, all power and water sources are turned off, the elastic pressure roller is raised, and the worker removes the clamping base to replace it with the next batch of sea cucumbers to be cleaned.

[0029] This invention utilizes a rotating insert and a fixed sea cucumber. The spiral guide ribs on the insert surface effectively knead, comb, and shear within the sea cucumber's abdominal cavity, mimicking the action of manual finger cleaning. Combined with water jetting, it effectively removes viscera, mesentery, and sediment, solving the problem of inadequate cleaning by traditional equipment. The modular clamping base design enables offline unloading and online cleaning. Workers can pre-process and clamp the sea cucumbers onto the base outside the production line, allowing for rapid automated cleaning and reducing equipment waiting time, making it suitable for continuous production lines.

[0030] In an optional embodiment, such as Figure 1As shown, the cleaning station 110 is equipped with a lifting plate 120 and a liftable elastic pressing mechanism (not shown in the figure) on the lifting plate, which is used to gently press down on the outer wall of the sea cucumber sleeved on the insertion post during cleaning.

[0031] In this embodiment, after the clamping base is in place and a signal is sent to begin operation, a small cylinder or servo electric push rod is driven to lower the entire elastic pressing mechanism. The elastic pressing mechanism has an elastically retractable gripper for each sea cucumber on the insertion post. The gripper gently abuts against the outer wall of the sea cucumber, fixing it relatively in place. It is not necessary to completely fix the sea cucumber to avoid damage; minimizing its rotation with the insertion post is sufficient. After cleaning, the elastic pressing mechanism automatically lifts up. It should be noted that the power system and control method for raising and lowering the elastic pressing mechanism use conventional methods of existing technology, which will not be elaborated upon here. This embodiment prevents the sea cucumber from rotating completely synchronously with the insertion post, ensuring that the guide ribs and water flow on the insertion post can generate relative movement and shear force with the inner wall of the sea cucumber's abdominal cavity.

[0032] In an optional embodiment, such as Figure 2 As shown, the lower surface of the insertion post 300 is provided with at least two guide grooves 380. The guide grooves 380 start from the lower surface of the insertion post and extend towards its bottom end. The guide grooves are grooves machined on the lower outer surface of the insertion post, with their starting end located below the lowest set of radial spray holes and their ending end extending to a position close to the worktable. The inner surface of the guide grooves has a smooth transition to minimize the possibility of impurity adhesion. During the cleaning process, the detached impurities fall naturally to the bottom of the insertion post under the influence of gravity, water flow impact, and the pushing force of the guide ribs. The guide grooves guide these substances and allow them to be smoothly discharged from the cut at the bottom of the sea cucumber. This embodiment provides a low-resistance outflow path for the washed-off viscera, mud, and other impurities, preventing them from accumulating or clogging at the bottom of the insertion post.

[0033] In an optional embodiment, the spiral guide ribs have a frosted surface layer at their outermost radial position. The frosted surface layer is a surface treatment process that allows for direct sandblasting of the guide rib area during the manufacturing of the insert. This embodiment generates greater static and sliding friction between the guide ribs and the soft, moist inner wall of the sea cucumber, enhancing the kneading effect. The micro-cutting action formed by the frosted surface more effectively scrapes away tightly adhered mucus and fine sand.

[0034] In an optional embodiment, the radial height of the spiral guide rib varies along its axial direction, with the radial height of its central region being greater than that of its two end regions. Specifically, the radial height of the guide rib in the middle of the insertion post is the greatest, gradually decreasing towards both ends (head and tail direction). For example, the height of the protrusion in the middle of the guide rib is 1-3 mm higher than that at both ends. This height difference is sufficient to generate an effective pressure gradient without hindering the insertion of the sea cucumber or causing damage. When the insertion post rotates, the protrusion in the middle will generate stronger kneading and shearing forces on the middle section of the sea cucumber's abdominal cavity, simulating the action of rubbing the middle section of the sea cucumber with fingers during manual cleaning.

[0035] In an optional embodiment, the cross-section of the spiral guide rib is asymmetrical, with different radii of curvature or inclination angles on its two side profiles. The left and right profiles of the spiral guide rib are designed with different slopes or shapes, such as one side being steep and the other gentle. Taking one guide rib as an example, its leading edge (relative to the direction of rotation) is set to be steeper to generate a stronger instantaneous thrust, while the trailing edge is set to be relatively gentle, providing a soft release. This asymmetrical structure on both sides can generate an effective lateral excitation to the sea cucumber in each rotation. When the insertion post rotates at a constant speed, the asymmetrical profile will generate a periodic, left-right asymmetrical radial force on the inner wall of the sea cucumber. This periodically changing force will force the soft sea cucumber body wall to produce a slight, passive left-right sway, simulating manual cleaning, where the sea cucumber is held and shaken back and forth, using inertia to shake off loosened visceral fragments.

[0036] In an optional embodiment, such as Figure 2 and Figure 3 As shown, the top of the insertion post 300 is provided with an annular spray hole 390, which communicates with the hollow cavity 330 to form an umbrella-shaped water curtain sprayed outward and downward toward the insertion post 300. The annular spray hole is an annular slit at the upper part of the insertion post, with a slit width between 0.5mm and 1.0mm. The spray direction is outward and downward toward the insertion post, and the angle between the slit and the axis of the insertion post is between 30° and 45°, ensuring that the water curtain can effectively cover the inner wall of the shoulder. After the high-pressure water flow enters the hollow chamber, a portion of it is ejected through the annular jet holes. With the help of the rotating insert, this water curtain provides a comprehensive flushing of the top of the sea cucumber's abdominal cavity. The cut shoulder area of ​​the sea cucumber is a blind end of the abdominal cavity, which is difficult to effectively cover with traditional radial water flow. The umbrella-shaped water curtain formed by the annular jet holes flushes this area from top to bottom. Before the water flow enters the deep part of the abdominal cavity, it first flushes the top and evenly wets the entire inner wall of the abdominal cavity, preparing for subsequent deep cleaning and eliminating cleaning dead zones in this area.

[0037] In an optional embodiment, each of the multiple sets of radial injection holes is arranged in a circumferential array, and the injection angle of each radial injection hole unit in the same set of radial injection holes is different. That is, the holes in the same circumferential group have different axial directions and radial directions of the insertion post. In the same set, the angle between each injection hole unit and the normal of the insertion post surface is different, such as 0° (vertical), +15° (slanted upward), -15° (slanted downward), etc.

[0038] In this embodiment, water jets are simultaneously ejected from nozzles at different angles, creating a complex three-dimensional flow field within the fixed abdominal cavity of the sea cucumber. This flow impacts and removes impurities from all directions. The water jets at different angles collide and reflect each other within the abdominal cavity, forming a highly turbulent and thorough cleaning network.

[0039] In an optional embodiment, such as Figure 3 As shown, the drive wheel 210 and the driven gear 220 are connected by a synchronous belt. Synchronous belt drives are flexible and can absorb vibration and impact, resulting in smoother equipment operation and reduced noise compared to pure gear drives.

[0040] In an optional embodiment, the device further includes a pulse water flow generator electrically connected to the control unit, the pulse water flow generator being disposed in the water path inside the workbench for modulating the water flow delivered to the radial jet orifice into a periodically changing pulse water flow.

[0041] The control unit in this embodiment is a PLC or a microcontroller. This control unit can serve as the central control for the pulse water flow generator, drive motor, or even the water pump using common control methods in the prior art, thereby realizing the periodically changing pulse water flow in this embodiment. The pulse water flow generates peak pressures that are much higher than constant water flow in an instant. This periodic shock wave (water hammer effect) has a strong physical tearing and peeling effect on tightly attached viscera and mesentery.

[0042] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
