Description

Technical Field

[0001] This invention relates to the field of deep-sea fishing equipment technology, specifically to a squid storage and automatic processing system for deep-sea squid fishing vessels. Background Technology

[0002] Deep-sea squid fishing is characterized by its long operating areas, large catch volume, and continuous operation. After the squid are hooked, they need to be quickly stored, cleaned, drained, and transported to ensure freshness and quality, while also meeting the demands of limited cabin space and continuous operation on fishing vessels. Currently, squid processing on deep-sea squid fishing vessels relies heavily on manual labor and simple equipment. This fragmented process has low automation, making it difficult to match the pace of large-scale continuous fishing operations. Furthermore, the rough seas of the vessel can cause squid to pile up and be damaged, affecting the yield of the finished product.

[0003] Existing squid processing equipment lacks an adaptive control mechanism that matches the real-time squid feeding volume. Most of them operate with fixed parameters, which can easily lead to incomplete cleaning or waste of water and energy when the feeding volume fluctuates. At the same time, squid tend to pile up and stick together during processing, resulting in poor cleaning and draining effects, which makes it difficult to meet the needs of stable operation and efficient storage in the confined space of ocean-going squid fishing vessels. Summary of the Invention

[0004] The purpose of this invention is to provide a squid storage and automatic processing system for use on ocean-going squid fishing vessels, in order to solve the problem that existing squid processing equipment lacks an adaptive control mechanism that matches the real-time feeding volume of squid, and mostly operates with fixed parameters. When the feeding volume fluctuates, problems such as incomplete cleaning or waste of water and energy resources are likely to occur.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A squid storage and automatic processing system for use on a deep-sea squid fishing vessel includes: a feeding assembly, an automatic processing module, a discharging module, and a controller;

[0007] An automatic processing module includes a processing chamber, a cleaning tank disposed on the bottom wall of the processing chamber, a partition mesh plate fixed to the inner wall of the cleaning tank, a conveyor belt driven and installed above the partition mesh plate, a bubble blower installed in the processing chamber, a conduit connected to the output end of the bubble blower, a branch pipe connected between the conduit and the cleaning tank, a plurality of bubble outlets connected to the periphery of the branch pipe, a spray pipe array disposed above the cleaning tank, and a plurality of first atomizing nozzles installed on the periphery of the spray pipe. The bubble outlets are connected to the bottom of the conveyor belt, and an inclined lifting conveyor section is connected to one side of the conveyor belt.

[0008] The feeding assembly includes a feeding port located on one side of the processing chamber, a guide slope connecting the feeding port and the cleaning tank, a receiving hopper rotatably installed on the side wall of the guide slope, and an adjustment assembly for controlling the rotation of the receiving hopper. A pressure sensor is installed on the bottom surface of the guide slope. The controller integrates a dynamic matching algorithm for cleaning parameters. The pressure sensor collects the pressure signal of the squid in the receiving hopper in real time and transmits it to the controller. The controller calculates the real-time feeding amount based on the pressure signal and then adjusts the bubbling intensity of the bubbler and the spray pressure and frequency of the first atomizing nozzle and the second atomizing nozzle synchronously through the dynamic matching algorithm for cleaning parameters to achieve dynamic adaptation between the feeding amount and cleaning parameters.

[0009] The discharge module includes a discharge port located on the other side of the processing chamber, a discharge hopper installed at the discharge end of the inclined lifting conveyor section, and a conveyor belt installed inside the processing chamber, the conveyor belt being located below the discharge hopper.

[0010] Furthermore, a discharge pipe is installed on the bottom surface of the cleaning tank, and a control valve is installed at the end of the discharge pipe.

[0011] Furthermore, the calculation formula for the dynamic matching algorithm of the cleaning parameters is as follows:

[0012] Material feed conversion: M = k × P avg ;

[0013] Where M is the real-time feeding rate (kg / min), k is the preset conversion factor, and P avg The effective average pressure (kPa) collected by the pressure sensor;

[0014] Cleaning parameter adjustment: Q=k1×M, P spray =k2×M, f=k3×M;

[0015] Where Q is the bubbling intensity of the bubbling machine, and P... spray f is the spray pressure of the atomizing nozzle, f is the spray frequency, and k1, k2, and k3 are the preset adjustment coefficients of the corresponding parameters, so as to realize the dynamic adaptation of the feed amount and cleaning parameters.

[0016] Furthermore, the adjustment assembly includes a hydraulic push rod hinged to the side wall of the processing chamber and a connecting seat fixed to the bottom of the receiving hopper, wherein the telescopic end of the hydraulic push rod is hinged to the connecting seat.

[0017] Furthermore, a hinge is provided on the side wall of the receiving hopper, and the hinge is rotatably connected to the side wall of the guide slope.

[0018] Furthermore, the conveyor belt is provided with partitions on its periphery, which evenly separate the squid carried by the conveyor belt, preventing the squid from piling up together during the transport and cleaning process, thus avoiding inconvenience in cleaning.

[0019] Furthermore, it also includes a material leveling component, which includes a fixed frame fixedly installed above the conveyor belt, a servo motor installed on the upper surface of the fixed frame, and a swing arm installed at the output end of the servo motor.

[0020] Furthermore, the tilt angle of the inclined lifting conveyor section is 30°-45°, and anti-slip ridges are provided on the surface of both the conveyor belt and the inclined lifting conveyor section.

[0021] Compared with existing technologies, the present invention provides a squid storage and automatic processing system for deep-sea squid fishing vessels. By setting up a feeding component, an automatic processing module, a discharging module and a controller, and by using a pressure sensor and a dynamic matching algorithm for cleaning parameters, the system achieves real-time adaptation of the feeding amount and processing parameters, thereby improving cleaning efficiency and energy saving. The overall structure is compact and adaptable to the limited space of deep-sea squid fishing vessels, meeting the needs of efficient, stable and automated deep-sea squid fishing operations.

Detailed Implementation

[0028] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] As attached Figure 1 To be continued Figure 4 As shown:

[0030] Example 1: This invention provides a squid storage and automatic processing system for use on a deep-sea squid fishing vessel, including a feeding assembly, an automatic processing module, a discharging module, and a controller;

[0031] The automatic processing module includes a processing chamber 1, a cleaning tank 2 set on the bottom wall of the processing chamber 1, a partition mesh plate 201 fixed on the inner wall of the cleaning tank 2, a conveyor belt 7 driven and installed above the partition mesh plate 201, a bubble blower 3 installed in the processing chamber 1, a conduit 4 connected to the output end of the bubble blower 3, a branch pipe 5 connected between the conduit 4 and the cleaning tank 2, a plurality of bubble outlets 6 connected to the periphery of the branch pipe 5, a spray pipe 10 arrayed above the cleaning tank 2, a plurality of first atomizing nozzles 11 installed on the periphery of the spray pipe 10, the bubble outlets 6 are connected to the bottom of the conveyor belt 7, an inclined lifting conveyor section 8 is connected to one side of the conveyor belt 7, a plurality of second atomizing nozzles 12 are arrayed on the inner wall of the inclined lifting conveyor section 8, a discharge pipe 202 is installed on the bottom surface of the cleaning tank 2, and a control valve is installed at the end of the discharge pipe 202.

[0032] The feeding assembly includes a feed inlet 101 located on one side of the processing chamber 1, a guide slope 103 connecting the feed inlet 101 and the cleaning tank 2, a receiving hopper 13 rotatably installed on the side wall of the guide slope 103, and an adjustment assembly for controlling the rotation of the receiving hopper 13. A pressure sensor 104 is installed on the bottom surface of the guide slope 103. The controller integrates a dynamic matching algorithm for cleaning parameters. The pressure sensor 104 collects the pressure signal of the squid in the receiving hopper 13 in real time and transmits it to the controller. The controller calculates the real-time feeding amount based on the pressure signal and then adjusts the bubbling intensity of the bubbler 3 and the spray pressure and frequency of the first atomizing nozzle 11 and the second atomizing nozzle 12 synchronously through the dynamic matching algorithm for cleaning parameters to achieve dynamic adaptation between the feeding amount and cleaning parameters.

[0033] The discharge module includes a discharge port 102 located on the other side of the processing chamber 1, a hopper 16 installed at the discharge end of the inclined lifting conveyor section 8, and a conveyor belt 17 installed inside the processing chamber 1, with the conveyor belt 17 located below the hopper 16.

[0034] The processing chamber 1 is a fully enclosed box structure, constructed entirely of 316L stainless steel sheet. All welded areas are fully welded and sealed, providing excellent waterproof, salt spray resistance, and resistance to deformation caused by sea turbulence. Its overall dimensions are designed according to the standard cabin space of a deep-sea squid fishing vessel, ensuring it does not occupy additional passage space or interfere with crew operations or the operation of other equipment on board. The processing chamber 1 has an inlet 101 on the left side wall and an outlet 102 on the right side wall. The internal space is divided into an inlet receiving area, a bubbling atomization cleaning area, an inclined lifting and draining area, and an outlet conveying area. The transitions between these areas are smooth, ensuring a seamless material transport process without backtracking, jamming, or accumulation.

[0035] In the feeding assembly, the guide slope 103 is an integrated smooth inclined panel, made of food-grade stainless steel by stamping, with a polished and passivated surface. The inclination angle is set to ensure that the squid can slide down smoothly entirely by its own weight. The upper end is seamlessly connected to the feed inlet 101, and the lower end extends precisely to the top of the conveyor belt 7 inside the cleaning tank 2, ensuring that the squid can fall completely into the effective conveying area. The receiving hopper 13 is a bucket-shaped structure with a large opening at the top and a narrow opening at the bottom. It is made of thickened stainless steel by stamping, and the side wall is integrally formed with a hinge part 1301. The hinge part 1301 is rotatably connected to the side wall of the guide slope 103 through a high-precision pin. The receiving hopper 13 can rotate stably in the vertical plane around the hinge part 1301, realizing a stable switching between the two states of receiving and storing materials and rotating and discharging materials.

[0036] The adjustment assembly consists of a hydraulic push rod 14 and a connecting seat 15. The fixed base of the hydraulic push rod 14 is fixedly installed on the outer left side of the processing chamber 1 through a high-strength hinge support. The telescopic end of the hydraulic push rod 14 is hinged to the connecting seat 15 through a pin. The connecting seat 15 is fixed to the bottom center of the receiving hopper 13 by welding, so that the force is uniform and does not deform. The telescopic movement of the hydraulic push rod 14 can accurately drive the receiving hopper 13 to rotate around the hinge part 1301, accurately control the opening orientation and feeding speed of the receiving hopper 13, and realize the continuous quantitative feeding of squid or the pause feeding as needed. The pressure sensor 104 is a high-sensitivity patch-type waterproof pressure sensor, which is tightly attached and fixed to the center of the bottom surface of the guide slope 103 with strong adhesive. The sealing protection level meets the requirements for use in high-humidity marine environments. When the squid falls from the receiving hopper 13 into the guide slope 103 and slides downward, the pressure sensor 104 can collect the pressure signal generated by the squid on the guide slope 103 in real time, continuously and accurately, and convert the pressure analog signal into a digital electrical signal for continuous and stable transmission to the controller.

[0037] In the automatic processing module, the cleaning tank 2 is a closed water storage tank, fixedly and sealed inside the bottom wall of the processing chamber 1, used to store cleaning water. The tank body is sealed and waterproof on all sides and bottom, and there is no leakage during use. The dividing mesh plate 201 is a stainless steel plate with uniform and dense mesh, horizontally welded and fixed in the middle of the inner wall of the cleaning tank 2, rigidly dividing the internal space of the cleaning tank 2 into a lower air-water mixing chamber and an upper material processing chamber. The mesh aperture allows rising air bubbles and water flow to pass smoothly, while completely preventing squid from falling into the lower chamber, avoiding contact between squid and sewage and dirt. The conveyor belt 7 is an independently driven mesh belt conveyor mechanism, composed of a waterproof geared drive motor, a drive roller, a driven roller, and a high-strength polyethylene mesh belt body. It is stably installed above the dividing mesh plate 201. The mesh of the mesh belt body is evenly distributed, facilitating the smooth penetration of rising air bubbles and atomized water flow. The drive motor speed is stable and adjustable, and can be matched and matched with the overall cleaning process. Bubble machine 3 is a high-power, high-pressure air pump type bubble machine, which is fixedly and securely installed in the right corner of the processing chamber 1. The output end is sealed and connected to the conduit 4 through a sealing joint. The conduit 4 is a pressure-resistant, corrosion-resistant, and anti-aging flexible hose, which is arranged neatly along the inner wall of the processing chamber 1. The lower end extends into the cleaning tank 2 and is sealed and connected to the branch pipe 5. The branch pipe 5 is a horizontally arranged multi-hole stainless steel pipe, which is firmly fixed in the air-water mixing chamber at the bottom of the cleaning tank 2. Several bubble outlets 6 are opened at equal intervals on the periphery and sealed and connected. The bubble outlets 6 extend vertically upward, with the upper end precisely passing through the partition mesh plate 201. The port is vertically facing the lower surface of the conveyor belt 7. When the bubble machine 3 is working, the high-pressure air generated passes through the conduit 4 and the branch pipe 5 in sequence and is continuously sprayed upward from the bubble outlets 6, forming a dense and uniform rising bubble group, which performs all-round, no-dead-angle bubble flushing of the squid on the conveyor belt 7. The spray pipes 10 are multiple horizontally parallel stainless steel pipes arranged in a uniform array. The array is installed above the cleaning tank 2 and on both sides of the conveyor belt 7. The spray pipes 10 are uniformly connected to the marine seawater supply system. Each spray pipe 10 has several first atomizing nozzles 11 installed at equal intervals on one side facing the center of the conveyor belt 7. The first atomizing nozzles 11 can fully atomize the high-pressure seawater and spray it evenly on the surface of the squid, forming a two-way three-dimensional cleaning structure in conjunction with the bottom bubbling rinsing. The inclined lifting conveyor section 8 is an inclined mesh belt lifting mechanism. The bottom end is smoothly and seamlessly connected to the end of the conveyor belt 7. The inclination angle is fixed at 30°. The surface is provided with a basic anti-slip structure, which can effectively prevent the squid from sliding back during the lifting process.

[0038] The second atomizing nozzle 12 is installed in an array above the inclined lifting and conveying section 8. The second atomizing nozzle 12 is also connected to the marine seawater supply system to perform secondary atomizing spraying and final rinsing treatment on the squid during the lifting and conveying process, while also assisting in the lifting and draining effect.

[0039] In the discharge module, the hopper 16 is a funnel-shaped structure, wider at the top and narrower at the bottom, made of stainless steel through a single stamping process. It is precisely and fixedly installed directly below the high-end discharge port of the inclined lifting conveyor section 8, efficiently collecting the lifted squid and ensuring it falls stably onto the conveyor belt 17 below, completely preventing material spillage. The conveyor belt 17 is a horizontally arranged food-grade belt conveyor, stably installed inside the processing chamber 1 on the lower right side. The inlet end is precisely located directly below the hopper 16, and the outlet end extends smoothly to the inside of the outlet 102, ensuring that the processed squid is transported smoothly, continuously, and without damage to the outlet 102 for easy discharge.

[0040] In the sewage discharge structure, the discharge pipe 202 is a stainless steel corrosion-resistant sewage discharge pipe, which is vertically and sealed at the lowest position of the bottom surface of the cleaning tank 2. The upper end is connected to the inside of the cleaning tank 2, and the lower end extends to the outside of the treatment chamber 1. The end of the discharge pipe 202 is sealed with a manual / electric dual-purpose control valve. The control valve can be opened periodically according to the cleaning water quality to completely discharge the sewage, mucus and impurities generated during cleaning, quickly replenish the clean seawater, continuously maintain the clean water quality in the cleaning tank 2, and ensure stable cleaning effect.

[0041] The controller and algorithm section consists of an industrial-grade embedded waterproof controller, which is fixedly installed on the outer wall of the treatment chamber 1 in a position convenient for crew operation. It has a built-in high-precision signal acquisition module, a high-speed computing module, a multi-channel drive control module, and a fixed dynamic matching algorithm for cleaning parameters.

[0042] The raw pressure signal acquired by pressure sensor 104 is filtered, amplified, and noise-reduced to obtain the effective average pressure P. avg The controller is calibrated according to the formula M=k×P. avg Accurately calculate the real-time material feeding rate M, in kg / min, where k is the actual pressure-weight conversion factor calibrated on site (k is the shipborne measured calibration factor, which is only applicable to the guide slope working condition of this system).

[0043] The controller synchronously adjusts three sets of core operating parameters according to the real-time material feed rate M using the following formula:

[0044] Bubble strength Q = k1 × M;

[0045] Spray pressure P spray =k2×M;

[0046] Spray frequency f = k³ × M;

[0047] k1, k2, and k3 are preset adjustment coefficients that are determined on-site based on the squid species, size, and cleaning requirements.

[0048] The controller outputs corresponding control signals to the bubble machine 3, the spray water pump, and the spray solenoid valve in real time, and dynamically adjusts the amount of bubbling air, the spray pressure and switching frequency of the first atomizing nozzle 11 and the second atomizing nozzle 12 in real time, so as to achieve dynamic optimal adaptation of "more fish, more washing; fewer fish, less washing".

[0049] Working Principle: After the system is powered on and initialized, it enters a stable standby state. The squid caught by the squid fishing machine is smoothly fed into the feed inlet 101 of the processing chamber 1 via a special conveyor mechanism on the ship. The squid first fall into the receiving hopper 13 for temporary storage to avoid impact and accumulation caused by direct feeding. The controller controls the hydraulic push rod 14 to perform periodic extension and retraction movements according to the preset operation sequence. When the hydraulic push rod 14 extends and retracts, it drives the receiving hopper 13 to rotate downwards and stably around the hinge part 1301 through the connecting seat 15. The squid temporarily stored in the receiving hopper 13 falls smoothly into the guide slope 103 by its own gravity. The squid slides continuously, smoothly and without jamming onto the conveyor belt 7 above the washing tank 2 along the smooth surface of the guide slope 103, completing the automatic receiving and precise quantitative feeding of squid.

[0050] Throughout the squid's descent along the guide slope 103, the pressure sensor 104, which is tightly attached to the bottom surface of the guide slope 103, continuously, in real time, and with high precision collects the pressure signal generated by the squid's descent. After processing, the pressure signal is stably transmitted to the controller. The controller, through a built-in dynamic matching algorithm for cleaning parameters, calculates the effective average pressure P collected by the pressure sensor 104. avg The data is accurately converted to the current real-time feeding quantity M, and the corresponding bubbling intensity Q and spray pressure P are calculated and matched based on the real-time feeding quantity M. spray The spraying frequency f is then synchronously output with multiple control signals to adjust the output air volume of the bubbler 3, the working pressure of the spray water pump, and the switching frequency of the first atomizing nozzle 11 and the second atomizing nozzle 12 in real time. When the amount of material increases, the cleaning intensity is automatically increased, and when the amount of material decreases, the cleaning intensity is automatically reduced, so as to achieve dynamic and precise matching between the amount of material and the cleaning parameters throughout the process, which ensures the cleaning effect and avoids the waste of water resources and energy.

[0051] After the squid lands stably on the conveyor belt 7, it is continuously transported forward at a constant speed. The bubble machine 3 at the bottom of the cleaning tank 2 continuously generates high-pressure air. The high-pressure air passes through the duct 4 and the branch pipe 5 in sequence and is continuously sprayed upward from the bubble outlet 6 into a dense and uniform cluster of rising bubbles. The bubble cluster powerfully, comprehensively, and thoroughly washes the surface of the squid from the bottom, effectively removing mucus, scales, seawater impurities, and other dirt from the surface of the squid. At the same time, the spray pipe 10 above the cleaning tank 2 sprays atomized seawater evenly downward through the first atomizing nozzle 11, continuously spraying and rinsing the upper surface of the squid. The two-way synergy achieves three-dimensional, thorough cleaning of the squid, greatly improving cleaning efficiency and cleanliness.

[0052] After the squid has completed the bubbling and atomized spray cleaning, it smoothly enters the inclined lifting conveyor section 8 from the end of the conveyor belt 7. The squid is continuously lifted and conveyed upward along the inclined lifting conveyor section 8. During the lifting process, the excess water carried on the surface of the squid drips down by its own gravity, completing the natural drainage action. At the same time, the second atomizing nozzles 12 installed in the array on the inner wall of the inclined lifting conveyor section 8 continuously spray atomized seawater to perform secondary rinsing and final cleaning of the squid, further removing residual dirt and improving the appearance quality and cleanliness of the squid.

[0053] After draining and rinsing, the squid falls smoothly from the high-end discharge port of the inclined lifting conveyor section 8, and is efficiently gathered by the discharge hopper 16 before falling precisely onto the lower conveyor belt 17. The conveyor belt 17 operates continuously at a stable speed, smoothly and without damage transporting the processed squid to the discharge port 102. After being successfully discharged from the discharge port 102, the squid can be directly put into the ship's refrigerated storage equipment, completing the fully automated processing and storage preparation work.

[0054] During continuous operation of the system, the wastewater, dirt, and sludge generated during cleaning will gradually settle to the bottom of the cleaning tank 2. Depending on the turbidity of the cleaning water, the crew can periodically open the control valve at the end of the discharge pipe 202 to completely discharge the wastewater and dirt in the cleaning tank 2 to the outside of the treatment chamber 1. Then, the control valve is closed and fresh clean seawater is added to ensure that the water quality in the cleaning tank 2 remains clean, thus ensuring the long-term stable operation of the system and a stable cleaning effect.

[0055] Example 2: Based on the complete structure of Example 1, this example adds several partitions 9 to the upper surface of the conveyor belt 7, arranged in an array and fixed vertically along the conveying direction. The partitions 9 are made of flexible food-grade rubber, with a uniform height of 4cm and a width that is exactly the same as the effective width of the conveyor belt 7. The partitions 9 are evenly spaced, rigidly dividing the conveyor belt 7 into multiple independent material holding units. Each unit can independently hold one or more squid, structurally preventing the squid from laterally gathering, stacking, squeezing, or sticking together during the conveying and cleaning process, thus completely eliminating cleaning dead corners.

[0056] Working Principle: After the squid caught by the squid fishing machine falls through the feed inlet 101, receiving hopper 13, and guide slope 103, they are directly separated into independent material receiving units by the partitions 9 on the conveyor belt 7. Throughout the continuous forward transport of the squid with the conveyor belt 7, the squid are rigidly confined within their independent units by the partitions 9, preventing them from gathering, overlapping, being squeezed, or sticking to either side of the conveyor belt 7. The entire surface of each squid is fully exposed to the rising bubbles and atomized spray water. The bubbles and water can fully contact every surface of the squid, completely eliminating the cleaning dead corners caused by stacking in traditional equipment. This ensures that each squid is fully, evenly, and thoroughly cleaned, while preventing squid from squeezing each other and causing skin damage or breakage, significantly improving the yield and quality uniformity. Except for the above-mentioned anti-stacking and separation cleaning action, all working principles such as material receiving and unloading, pressure detection, parameter adaptive adjustment, bubble spraying, inclined lifting and draining, material discharge and conveying, and periodic sewage discharge are completely consistent with those in Example 1, without any modifications.

[0057] Example 3: A special material leveling component is added above the conveyor belt 17: The fixed frame 18 is a portal-type high-strength stainless steel bracket, which is firmly fixed at both ends to the inner wall of the processing chamber 1 and spans directly above the conveyor belt 17 without interfering with the normal operation of the conveyor belt 17; the servo motor 19 is horizontally and sealed and fixedly installed at the center of the upper surface of the fixed frame 18, and its output axis passes vertically downward through the fixed frame 18 and is rigidly fixedly connected to the swing rod 20; the swing rod 20 adopts a round rod or flat rod structure, and its length is slightly less than the effective width of the conveyor belt 17. The lower end is kept 1-2 cm away from the upper surface of the conveyor belt 17. The servo motor 19 can drive the swing rod 20 to swing back and forth at a uniform speed, so as to evenly and gently flatten the squid locally accumulated on the conveyor belt 17 into a single layer.

[0058] Working principle: Squid falling onto the conveyor belt 17 after passing through the inclined lifting conveyor section 8 and the unloading hopper 16 are prone to localized accumulation. At this time, the servo motor 19 on the fixed frame 18 continuously drives the swing rod 20 to swing back and forth stably. The swing rod 20 gently and evenly spreads and disperses the squid locally accumulated on the conveyor belt 17 to both sides, so that the squid are completely arranged in a single layer evenly on the conveyor belt 17.

[0059] After being continuously conveyed to the discharge port 102, the squid arranged in a single layer can be directly, neatly and orderly placed into the ship's refrigerated box or storage rack. This avoids local heating, spoilage and squid damage caused by large-scale accumulation, and is more conducive to long-term low-temperature storage of squid, greatly improving storage quality and subsequent processing convenience.

[0060] Example 4: The tilt angle of the inclined lifting conveyor section 8 is set within the range of 30°–45°; at the same time, high-density trapezoidal anti-slip ridges are integrally formed on the surfaces of the conveyor belt 7 and the inclined lifting conveyor section 8. The anti-slip ridges have a protrusion height of 2mm and a spacing of 5mm, which can significantly increase the friction between the surface of the belt and the squid skin, and structurally prevent the squid from slipping, sliding, or flowing back during the conveying and lifting process.

[0061] Working principle: During the system installation phase, the crew can flexibly set the tilting lifting and conveying section 8 between 30° and 45° according to the actual size, height, and layout of the installation compartment on the ocean-going squid fishing vessel. When the horizontal space of the compartment is small, the tilting lifting and conveying section 8 is adjusted to a 45° tilt angle to save the horizontal space to the greatest extent. When the compartment space is sufficient and the drainage time needs to be extended, the tilting lifting and conveying section 8 is adjusted to a 30° tilt angle to extend the squid drainage stroke and improve the drainage effect. After adjustment, it is rigidly locked by the locking mechanism to ensure that it does not loosen or deform during operation.

[0062] Throughout the squid conveying and tilting process, the high-density trapezoidal anti-slip ridges on the surface of the conveyor belt 7 and the tilting conveyor section 8 can significantly increase the frictional force between the conveyor belt and the squid skin. Even under the harsh conditions of turbulence, shaking, and tilting of the ocean-going squid fishing vessel, the squid will not slip, slide, flow back, or accumulate, ensuring continuous, stable, and smooth material conveying throughout the entire process, and greatly improving the system's operational stability and reliability under complex marine conditions.

[0063] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
