Description

Technical Field

[0001] This invention relates to the field of aquatic product preservation technology, specifically to a freezing and preservation device for aquatic products. Background Technology

[0002] Freezing and preserving aquatic products involves low-temperature freezing, rapid freezing, and sealing to prevent oxygenation, thereby inhibiting microbial growth, slowing down enzyme activity and oxidation, achieving long-term preservation, maintaining meat quality and flavor, and extending shelf life.

[0003] Patent publication number CN107836628A describes a structure including control buttons, a display screen, a control panel, a movable sealing plate, a handle, a storage box, edging lines, a refrigeration box, heat dissipation holes, a power supply unit, and casters. Four casters are evenly distributed at the four corners of the bottom of the power supply unit. The storage box has edging lines on its upper and lower outer rings via a snap-fit ​​mechanism. The refrigeration box uses a weighing plate to control the main push rod, which in turn pushes the lifting guide sleeve inside the box. A linkage rod controls the transmission mechanism, which in turn adjusts the regulating rod to regulate the cooling air in the temperature-controlled box. This allows for automatic adjustment of the cooling air volume based on the volume of aquatic products, effectively preventing energy waste in the refrigeration and freezing system and saving operating costs.

[0004] The aforementioned technology controls the main push rod to push the lifting guide sleeve inside the box, and controls the transmission mechanism through the linkage rod, thereby adjusting the regulating rod to regulate the cold air in the temperature-controlled box. It can automatically adjust the cold air volume according to the volume of aquatic products, effectively preventing energy waste in the freezing and refrigeration unit and saving operating costs. However, the device still adopts an integrated box-type preservation structure and does not achieve zoned or differentiated refrigeration control. When only a small amount of aquatic products are stored in the box, the entire internal space of the box still needs to be frozen, and it is impossible to target the aquatic product storage area with localized refrigeration, resulting in unnecessary energy consumption. At the same time, its freezing and preservation process uses a direct-blowing refrigeration method where low-temperature cold air directly contacts the aquatic products. The low-temperature cold air acts directly on the surface of the aquatic products, which can easily cause problems such as frostbite on the skin, moisture loss, and tissue shrinkage. This not only damages the texture and nutritional integrity of the aquatic products, but also seriously affects their appearance and significantly reduces their commercial value. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a freezing and preservation device for aquatic products, solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a freezing and preservation device for aquatic products, comprising a water tank, casters, a freezing and preservation box, and a door, wherein the casters are mounted on the water tank, the freezing and preservation box is mounted on the water tank, and the door is mounted on the freezing and preservation box; the freezing and preservation device for aquatic products further comprises: Drive motor; The freezing and preservation device includes a modular preservation mechanism installed on the freezing and preservation box and an intelligent start-stop mechanism installed on the freezing and preservation box; The modular preservation mechanism includes a gear 1 mounted on the drive motor, a gear 1 mounted on the door, a gear 2 mounted on the freezer preservation box, a preservation module box mounted on the freezer preservation box, a box cover mounted on the preservation module box, a sealing plate mounted on the box cover, a contact rod mounted on the box cover, a linkage rod 1 mounted on the contact rod, and a telescopic spring rod 1 mounted on the freezer preservation box. The freezing and preservation device is used to freeze and preserve aquatic products inside the freezing and preservation box. The modular preservation mechanism preserves aquatic products that need to be preserved in layers and modules. The intelligent start-stop mechanism is used to activate the freezing and preservation effect by returning the preservation module box to its original position.

[0007] The intelligent start-stop mechanism includes a battery installed on the freezer compartment, a connection port one installed on the battery, a telescopic spring rod two installed on the freezer compartment, a pressure plate installed on the free end of the telescopic spring rod two, a connection port two installed on the pressure plate, a connecting wire installed on the connection port two, and a cooling plate installed on the freezer compartment.

[0008] Gear 1 meshes with Gear 2. The inner wall of the preservation module box is set as an inclined surface. A circulation hole 1 is opened on the surface of the box cover. A circulation hole 2 is opened on the surface of the sealing plate. The circulation hole 1 and circulation hole 2 overlap. The end of the linkage rod 1 away from the contact rod is connected to the sealing plate. The free end of the telescopic spring rod 1 is connected to the contact rod.

[0009] The battery is electrically connected to the connection port, and the pressure plate is shaped like an arc.

[0010] The freezing and preservation device also includes a partition frost scraping device installed on the freezing and preservation box. The partition frost scraping device includes a cleaning and frost scraping mechanism installed on the freezing and preservation box and a vibration auxiliary mechanism installed on the cleaning and frost scraping mechanism. The partition and frost-scraping device is used to separate the inner wall of the freezer compartment from the preservation module box and to clean the inner wall of the freezer compartment. The frost-removing mechanism is used to clean the frost buildup on the inner wall of the freezer compartment; The vibration-assisted mechanism uses vibration to help clean the frost buildup on the inner wall of the freezer compartment.

[0011] The cleaning and frost-scraping mechanism includes a partition plate installed on the freezer compartment, a sliding frame installed on the pressure plate, a rotating rod installed on the sliding frame, a contact roller installed on the rotating rod, and a frost-scraping roller installed on the rotating rod. The partition plate has ventilation holes on its surface, the sliding frame is connected to the partition plate, the contact roller is in contact with the freezer, and the circumferential surface of the frost scraper is provided with bristles.

[0012] The vibration assist mechanism includes a cam mounted on the rotating rod, a sliding block mounted on the sliding frame, and a striking block mounted on the sliding block; Wherein, the end of the sliding block near the cam is set as arc surface one, and the surface of the striking block is set as arc surface two.

[0013] The freezing and preservation device also includes a drainage and deodorization device installed on the preservation module box. The drainage and deodorization device includes an automatic drainage mechanism installed on the preservation module box and a feeding and deodorization mechanism installed on the sliding frame. The drainage and deodorization device is used to drain the water inside the preservation module box and deodorize the collected water. The automatic drainage mechanism is used to actively drain and transport the water accumulated inside the preservation module box; The deodorizing mechanism is used to deodorize the water inside the aquatic product storage area by adding chemicals.

[0014] The automatic drainage mechanism includes a telescopic spring rod three installed on the preservation module box, a limiting block installed on the free end of the telescopic spring rod three, a water supply pipe installed on the water storage tank, a leaking pipe installed on the water supply pipe, and a sealing sleeve installed on the leaking pipe; The surface of the preservation module box is provided with a drain outlet, and the surface of the drain pipe is provided with filter holes. The drain pipe coincides with the drain outlet.

[0015] The feeding and deodorizing mechanism includes a linkage rod 2 installed on the sliding frame, a feeding cylinder installed on the frozen food preservation box, a storage bin installed on the feeding cylinder, a fixing rod installed on the storage bin, a conveying pipe installed on the feeding cylinder, and a reagent cylinder installed on the frozen food preservation box; The medicine cylinder is connected to the conveying pipe, and the end of the fixed rod away from the storage bin is connected to the end of the linkage rod away from the sliding frame.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, by aligning circulation hole one and circulation hole two, the sealing plate moves to release the sealing limit on the circulation hole on the surface of the box lid. At this time, the aquatic products inside the preservation module box can be frozen. The circulation hole avoids direct cold air blowing, preventing problems such as frostbite, cracking, dehydration and shrinkage, and darkening of color in aquatic products such as shrimp, fish, and shellfish. This preserves the original shape, texture, and appearance of the aquatic products to the greatest extent. Connection port two transmits electricity to the refrigeration plate through the connection line. At this time, the refrigeration plate freezes the corresponding compartments inside the frozen preservation box. By freezing the modular units individually inside the frozen preservation box, unnecessary energy consumption is reduced, avoiding the energy waste of traditional integrated refrigeration units operating at full capacity. The refrigeration energy consumption is significantly reduced, and the refrigeration devices are prevented from being missed or accidentally turned on. The control logic is precise and sensitive, shortening the refrigeration response time and improving the safety and intelligence level of the equipment operation.

[0017] 2. In this invention, the rotating rod drives the frost scraper roller to rotate, which in turn drives the brush to rotate. The brush cleans the frost hanging on the inner wall and partition surface of the freezer compartment, preventing excessive frost buildup that could block cold air conduction and reduce cooling efficiency. It also prevents frost from corroding the inner wall of the freezer compartment and rusting the refrigeration and transmission components, reducing the probability of short circuits, jamming, and refrigeration failures. The striking block moves to contact and strike the surface of the sliding frame. The sliding frame vibrates under the striking action of the striking block, and this vibration is transmitted to the partition plate, assisting in cleaning any remaining frost on the partition plate surface. Simultaneously, the vibration of the sliding frame provides a self-cleaning effect on the circumference of the frost scraper roller, ensuring that the heat exchange efficiency of the refrigeration components is always at its optimal level, and that the freezing speed and temperature stability are not affected by frost accumulation.

[0018] 3. In this invention, the water inside the preservation module box enters the water supply pipe through filter holes on the surface of the drain pipe, precisely intercepting the aquatic products themselves and only draining the water. This prevents small aquatic products such as shrimp, shellfish meat, and fish roe from being lost with the drainage, minimizing raw material loss. Subsequently, the water supply pipe transports the water into the storage tank, eliminating the water inside the preservation module box and preventing the water from enveloping the aquatic products, causing them to soak and spoil, resulting in a poor taste. At the same time, it prevents the water from diluting the cold air and reducing freezing efficiency, ensuring that the aquatic products are frozen evenly and meet the preservation quality standards. The storage bin moves upward again to release the restriction on the delivery pipe, at which point the automatic dosing of the agents inside the storage tank is completed, preventing the water from fermenting and spoiling, producing odors, and preventing odors from entering the freezing compartment and contaminating the aquatic products, ensuring that the aquatic products are odorless and free of excessive bacteria.

[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 Figures 1-5 One embodiment of the present invention is as follows: A freezing and preservation device for aquatic products includes a water storage tank 1, casters 11, a freezing and preservation box 2, and a door 21. The casters 11 are mounted on the water storage tank 1, the freezing and preservation box 2 is mounted on the water storage tank 1, and the door 21 is mounted on the freezing and preservation box 2. The freezing and preservation device for aquatic products further includes: Drive motor 22; The freezing and preservation device includes a modular preservation mechanism installed on the freezing and preservation box 2 and an intelligent start-stop mechanism installed on the freezing and preservation box 2; The modular preservation mechanism includes a gear 23 mounted on the drive motor 22, a gear 23 mounted on the door 21, a gear 24 mounted on the freezer preservation box 2, a preservation module box 31 mounted on the freezer preservation box 2, a box cover 32 mounted on the preservation module box 31, a sealing plate 33 mounted on the box cover 32, a contact rod 34 mounted on the box cover 32, a linkage rod 35 mounted on the contact rod 34, and a telescopic spring rod 36 mounted on the freezer preservation box 2. The freezing and preservation device is used to freeze and preserve aquatic products inside the freezing and preservation box 2. The modular preservation system allows for the layered and modular preservation of aquatic products that require preservation. The intelligent start-stop mechanism is used to activate the freezing and preservation effect by returning the preservation module box 31 to its original position.

[0023] The intelligent start-stop mechanism includes a battery 41 installed on the freezer compartment 2, a connection port 42 installed on the battery 41, a telescopic spring rod 43 installed on the freezer compartment 2, a pressure plate 44 installed on the free end of the telescopic spring rod 43, a connection port 45 installed on the pressure plate 44, a connecting wire 46 installed on the connection port 45, and a cooling plate 47 installed on the freezer compartment 2.

[0024] Gear 1 23 and gear 2 24 mesh with each other. The inner wall of the preservation module box 31 is set as an inclined surface to guide the accumulated water. The surface of the box cover 32 is provided with circulation hole 1, and the surface of the sealing plate 33 is provided with circulation hole 2. Circulation hole 1 and circulation hole 2 overlap, which facilitates sealing or unsealing. The end of the linkage rod 1 35 away from the contact rod 34 is connected to the sealing plate 33, and the free end of the telescopic spring rod 1 36 is connected to the contact rod 34.

[0025] Battery 41 is electrically connected to connection port 42. The pressure plate 44 is shaped like an arc, which is used to fit the preservation module box 31 to facilitate force application.

[0026] In this embodiment, during operation: When the worker places the aquatic products inside the preservation module box 31, the drive motor 22 is then started. The drive motor 22 rotates, driving gear 24 to rotate. Because gear 24 meshes with gear 1 23, the rotation of gear 24 drives gear 1 23 to rotate, which in turn drives the door 21 to rotate. At this time, the door 21 rotates, pushing the preservation module box 31 into the frozen preservation box 2. The movement of the preservation module box 31 drives the contact rod 34 to move. The contact rod 34 moves until it makes contact and moves under the pressure of the inner wall of the frozen preservation box 2. The movement of the contact rod 34 drives the linkage rod 35 to rotate. At this time, the rotation of the linkage rod 35 drives the sealing plate 33 to move. Since circulation hole 1 and circulation hole 2 coincide, the movement of the sealing plate 33 releases the sealing limit on the circulation hole on the surface of the box cover 32. At this time, the aquatic products inside the preservation module box 31 can be frozen. The circulation hole prevents cold air from blowing directly on the aquatic products, preventing the shrimp, fish, shellfish and other aquatic products from developing skin lesions. To prevent issues such as frostbite, cracking, dehydration, shrinkage, and darkening of color, the system preserves the original shape, texture, and appearance of aquatic products to the greatest extent possible. Simultaneously, the preservation module 31 moves to contact and press against the pressure plate 44, causing the second connection port 45 to move until it contacts the first connection port 42. At this point, because the battery 41 is electrically connected to the first connection port 42, the battery 41 transmits electricity through the first connection port 42 to the second connection port 45. The second connection port 45 then transmits the electricity through the connecting line 46 to the cooling plate 47. The cooling plate 47 then freezes the corresponding compartments inside the freezer-preservation box 2. This modular, individual freezing within the freezer-preservation box 2 reduces unnecessary energy consumption, avoiding the energy waste of operating the entire traditional freezer unit. Cooling energy consumption is significantly reduced, and the system prevents missed or accidental activation of cooling devices. The control logic is precise and sensitive, shortening the cooling response time and improving the safety and intelligence of the equipment.

[0027] Please see Figures 1-9 Based on the above embodiments, in another embodiment of the present invention, the freezing and preservation device further includes a partition frost scraping device installed on the freezing and preservation box 2. The partition frost scraping device includes a cleaning and frost scraping mechanism installed on the freezing and preservation box 2 and a vibration auxiliary mechanism installed on the cleaning and frost scraping mechanism. Among them, the partition frost scraping device is used to separate the inner wall of the freezer compartment 2 from the preservation module box 31 and to clean the inner wall of the freezer compartment 2; The frost-removing mechanism is used to clean the frost buildup on the inner wall of the freezer compartment 2; The vibration-assisted mechanism uses vibration to help clean the frost buildup on the inner wall of the freezer compartment 2.

[0028] The defrosting mechanism includes a partition plate 51 installed on the freezer compartment 2, a sliding frame 52 installed on the pressure plate 44, a rotating rod 53 installed on the sliding frame 52, a contact roller 54 installed on the rotating rod 53, and a defrosting roller 55 installed on the rotating rod 53. The partition plate 51 has ventilation holes on its surface to prevent the surface of the preservation module box 31 from contacting the surface of the freezer box 2 and thus freezing quickly. The sliding frame 52 is connected to the partition plate 51. The contact roller 54 contacts the freezer box 2. The circumferential surface of the frost scraper roller 55 is provided with bristles, which are used to clean the frost on the surfaces of the partition plate 51 and the freezer box 2.

[0029] The vibration assist mechanism includes a cam 56 mounted on a rotating rod 53, a sliding block 57 mounted on a sliding frame 52, and a striking block 58 mounted on the sliding block 57; Among them, the end of the sliding block 57 near the cam 56 is set as arc surface one, which is used to assist the cam 56 in contacting and receiving force. The surface of the striking block 58 is set as arc surface two, which is used to reduce the force-bearing surface and thus improve the striking effect.

[0030] In this embodiment, when the pressure plate 44 moves under the action of the preservation module box 31, the movement of the pressure plate 44 drives the sliding frame 52 to move, which in turn drives the rotating rod 53 to move. Simultaneously, the movement of the rotating rod 53 drives the contact roller 54 to move. Because the contact roller 54 is in contact with the inner wall of the freezer compartment 2, it rotates under the action of contact with the inner wall of the freezer compartment 2. At this time, the rotation of the contact roller 54 drives the rotating rod 53 to rotate, which in turn drives the frost scraper roller 55 to rotate. The rotation of the frost scraper roller 55 drives the brush to rotate, and the brush cleans the frost hanging on the inner wall of the freezer compartment 2 and the surface of the partition plate 51, preventing excessive frost buildup that could block cold air conduction and reduce the cooling effect. It also prevents the frost layer from corroding the inner wall of the freezer compartment. Rust on refrigeration and transmission components reduces the probability of equipment malfunctions such as short circuits, jamming, and refrigeration failure. Simultaneously, the rotating rod 53 rotates under the action of the contact roller 54, which drives the cam 56 to rotate. The rotating cam 56 contacts and presses the sliding block 57 to move. The movement of the sliding block 57 drives the striking block 58 to move. At this time, the striking block 58 contacts and strikes the surface of the sliding frame 52. The sliding frame 52 vibrates under the striking action of the striking block 58. The vibration of the sliding frame 52 is transmitted to the partition plate 51, which assists in cleaning the frost that has not been cleaned on the surface of the partition plate 51. At the same time, the vibration of the sliding frame 52 has a self-cleaning effect on the circumference of the frost scraper roller 55, ensuring that the heat exchange efficiency of the refrigeration components is always in the best state, and the freezing speed and temperature stability are not affected by frost accumulation.

[0031] Please see Figures 1-9Based on the above embodiments, in another embodiment of the present invention, the freezing and preservation device further includes a drainage and deodorization device installed on the preservation module box 31. The drainage and deodorization device includes an automatic drainage mechanism installed on the preservation module box 31 and a feeding and deodorization mechanism installed on the sliding frame 52. The drainage and deodorization device is used to drain the water inside the preservation module box 31 and deodorize the collected water. The automatic drainage mechanism is used to actively drain and transport the water accumulated inside the preservation module box 31; The deodorization system is used to deodorize the water inside the aquatic product storage area by adding chemicals.

[0032] The automatic drainage mechanism includes a telescopic spring rod 61 installed on the preservation module box 31, a limiting block 62 installed on the free end of the telescopic spring rod 61, a water supply pipe 63 installed on the water storage tank 1, a drain pipe 64 installed on the water supply pipe 63, and a sealing sleeve 65 installed on the drain pipe 64. The surface of the preservation module box 31 is provided with a drain outlet, and the surface of the drain pipe 64 is provided with filter holes. The filter holes are used to intercept small shrimp, shellfish meat and fish roe. The drain pipe 64 coincides with the drain outlet.

[0033] The feeding and deodorizing mechanism includes a linkage rod 66 installed on the sliding frame 52, a feeding cylinder 67 installed on the freezer box 2, a storage bin 68 installed on the feeding cylinder 67, a fixing rod 69 installed on the storage bin 68, a conveying pipe 610 installed on the feeding cylinder 67, and a reagent cylinder 611 installed on the freezer box 2. The agent cylinder 611 is connected to the conveying pipe 610, and the end of the fixed rod 69 away from the storage bin 68 is connected to the end of the linkage rod 66 away from the sliding frame 52.

[0034] In this embodiment, during operation: the preservation module box 31 moves towards the sealing ring 65 under the action of the box door 21. The movement of the preservation module box 31 drives the limiting block 62 to move. Then, the preservation module box 31 moves until the sealing ring 65 contacts the surface of the preservation module box 31 to waterproof the area that needs drainage. Then, the drain pipe 64 is inserted into the interior of the preservation module box 31. The drain pipe 64 contacts and squeezes the limiting block 62, moving it away from the sealing ring 65. At this time, the limiting block 62 moves until the sealing treatment of the drain outlet is released. Then, the drain pipe 64 enters the interior of the preservation module box 31. At this time, the water inside the preservation module box 31 enters the interior of the water supply pipe 63 through the filter holes opened on the surface of the drain pipe 64, accurately intercepting the aquatic products themselves and only draining the water. This avoids the loss of small aquatic products such as shrimp, shellfish meat, and fish roe with the drainage, minimizing raw material loss. Then, the water supply pipe 63 transports the water into the interior of the water storage tank 1, realizing the water supply of the preservation module box. The drainage of internal water prevents the aquatic products from becoming soaked and spoiled, resulting in a poor taste. It also prevents the water from diluting the cold air and reducing freezing efficiency, ensuring uniform freezing and maintaining the freshness of the aquatic products. When the sliding frame 52 moves under the action of the pressure plate 44, the movement of the sliding frame 52 drives the second linkage rod 66 to rotate. The rotation of the second linkage rod 66 drives the fixed rod 69 to move, which in turn drives the storage bin 68 to move. The storage bin 68 moves downward, pushing the stored medicine downward until it is added into the water storage tank 1. At this time, the top of the storage bin 68 restricts the conveying pipe 610, preventing it from continuously conveying medicine. When the sliding frame 52 resets, the storage bin 68 moves upward again, releasing the restriction on the conveying pipe 610. This completes the automatic medicine dispensing effect inside the water storage tank 1, preventing fermentation and spoilage of the water, the generation of odors, and preventing odors from entering the freezing chamber and contaminating the aquatic products, ensuring that the aquatic products are odorless and free of excessive bacteria.
