Description

Technical Field

[0001] The utility model relates to the field of freezing and refrigerating aquatic products, in particular to a freezing and refrigerating device for aquatic products. Background Art

[0002] Aquatic products are a general term for aquatic animal and plant products produced by marine and freshwater fisheries and their processed products, including: fresh fish, shrimp, crab, shellfish, algae, sea beasts and other live products produced by fishing and breeding; processed products that have been frozen, pickled, dried, smoked, cooked, canned and comprehensively utilized. Aquatic foods are rich in nutrients and have different flavors. Fish meal and concentrated fish juice made from low-value fish and processing waste are important protein feeds. Freezing of aquatic products refers to a low-temperature preservation method that uses low-temperature conditions to inhibit the activity of autolytic enzymes in aquatic products and the reproduction of attached microorganisms, and slows down the rate of chemical reactions such as lipid oxidation and non-enzymatic browning, so that they can maintain excellent quality during storage. Currently, freezing devices are used to store aquatic products to preserve their freshness. Refrigeration devices refer to mechanical equipment that uses a compressor to change the pressure change of refrigerant gas to achieve low-temperature refrigeration.

[0003] A Chinese patent discloses a refrigeration device for freezing aquatic products (authorization announcement number CN 214120477 U). This patented technology can solve the problem that most current refrigeration devices are directly stacked in an integral refrigeration box, which will cause uneven freezing of aquatic products and is extremely inconvenient for subsequent removal of aquatic products, or are placed in layers on trays. This layered placement requires workers to place trays filled with aquatic products in corresponding compartments. This placement method increases the difficulty of work for workers and reduces work efficiency for large refrigeration equipment.

[0004] However, the existing frame placed in the refrigerating room is prone to freezing, which makes it inconvenient to take out the frame, and when water leaks in the refrigerating room, it is easy to directly soak onto the floor and cause damage to it. Summary of the invention

[0005] In order to solve the above technical problems, the utility model provides a freezing and refrigerating device for aquatic products, comprising a cold storage box and a placement frame, wherein the placement frame is installed in the cold storage box by means of a snap-on connection, and an adjustment groove is symmetrically provided on the upper end surface of the cold storage box, wherein the adjustment groove is narrow at the top and wide at the bottom, and an outer cylinder is rotatably installed on the bottom of the adjustment groove through a bearing, an inner rod is rotatably installed on the inner wall of the outer cylinder through a thread, a driven bevel gear is installed on the outer wall of the outer cylinder, a driving bevel gear is meshingly and rotatably installed on the outer wall of the driven bevel gear, and an adjusting motor is installed on the outer end of the driving bevel gear.

[0006] Preferably, the inner rod and the adjusting slot are connected by sliding fit.

[0007] Preferably: a column is installed at the bottom of the refrigerator, a bottom cavity is installed at the bottom of the column, and moving wheels are installed at the bottom of the bottom cavity near the four corners.

[0008] Preferably: a water level sensor is embedded in the right end face of the column, through openings are symmetrically opened on the left and right side walls of the bottom cavity, a regulating valve is arranged in the through opening, and a fixed cavity is installed on the right end face of the through opening.

[0009] Preferably: a control panel is installed on the front end surface of the bottom cavity, and the control panel is electrically connected to the regulating valve.

[0010] Preferably, a plurality of limit racks are installed along the circumferential direction of the inner side wall of the bottom cavity, and the limit racks are closely attached to the outer side wall of the refrigerator.

[0011] Technical effects and advantages of the utility model:

[0012] 1. The utility model adopts a driving bevel gear and a driven bevel gear structure, so as to drive the inner rod to move upward, lift the placement frame, separate the placement frame from the refrigerator, and avoid freezing between the placement frame and the refrigerator, which makes it difficult to take out.

[0013] 2. The utility model adopts a bottom cavity and column structure. When the refrigerator leaks, it is prevented from flowing onto the floor and soaking it. There is a certain gap between the refrigerator and the bottom of the bottom cavity to prevent ice water from being adsorbed on the bottom of the refrigerator and damaging its internal structure.

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The invention of the present invention is given for the purpose of illustration and description, and is not intended to be exhaustive or to limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The invention is selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and design various inventions with various modifications suitable for specific purposes.

[0021] See also Figures 1 to 5 In this embodiment, a freezing and refrigerating device for aquatic products is provided, which includes a cold storage box 1 and a placement frame 2. The placement frame 2 is installed in the cold storage box 1 by a snap-on method. The upper end surface of the cold storage box 1 is symmetrically provided with adjustment grooves. The adjustment grooves are narrow at the top and wide at the bottom. An outer cylinder 11 is rotatably installed at the bottom of the adjustment groove through a bearing. An inner rod 12 is rotatably installed on the inner wall of the outer cylinder 11 through a thread. A driven bevel gear 13 is installed on the outer wall of the outer cylinder 11. A driving bevel gear 14 is meshed and rotatably installed on the outer wall of the driven bevel gear 13. An adjusting motor 15 is installed at the outer end of the active bevel gear 14. When working, the aquatic products are placed in the placement frame 2 for refrigeration. When the aquatic products need to be taken out, freezing is likely to occur between the placement frame 2 and the cold storage box 1, making it difficult to take out. At this time, the adjusting motor 15 is started, driving the active bevel gear 14 to rotate, and the active bevel gear 14 drives the driven bevel gear 13 to rotate, and the outer cylinder 11 rotates, so that the inner rod 12 moves up, and the inner rod 12 moves up to lift the placement frame 2, so that the placement frame 2 and the cold storage box 1 are separated.

[0022] The inner rod 12 is connected to the adjustment slot by a sliding fit. During operation, the sliding fit is adopted to ensure the stability of the inner rod 12 moving up and down.

[0023] The bottom of the refrigerator box 1 is installed with a column 16, and a bottom cavity 17 is installed at the bottom of the column 16. Moving wheels 18 are installed near the four corners of the bottom of the bottom cavity 17. When the refrigeration effect of the refrigerator box 1 is poor, resulting in water leakage, ice water enters the bottom cavity 17 to prevent it from flowing to the floor and soaking it. The column 16 structure is adopted to ensure that there is a certain gap between the refrigerator box 1 and the bottom of the bottom cavity 17 to prevent ice water from being adsorbed on the bottom of the refrigerator box 1 and damaging its internal structure.

[0024] A water level sensor 19 is embedded in the right end face of the column 16, and through openings 21 are symmetrically opened on the left and right side walls of the bottom cavity 17. A regulating valve is arranged in the through opening 21, and a fixed cavity 22 is installed on the right end face of the through opening 21. When working, the water level sensor 19 monitors the water level in the bottom cavity 17. When the water level is too high, the regulating valve opens to allow water to enter the fixed cavity 22 through the through opening 21, thereby lowering the water level and preventing it from causing damage to the bottom of the refrigerator 1.

[0025] A control panel 23 is installed on the front end surface of the bottom cavity 17. The control panel 23 is electrically connected to the regulating valve. When working, a PLC program is written in the control panel 23 to control the operation of each device.

[0026] The inner wall of the bottom cavity 17 is provided with a plurality of limit frames 24 along its circumferential direction. The limit frames 24 are in close contact with the outer wall of the refrigerator 1 . When in operation, the limit frames 24 limit and fix the refrigerator 1 to ensure the stability of the connection between the refrigerator 1 and the bottom cavity 17 .

[0027] During specific operation, the aquatic products are placed in the placement frame 2 for refrigeration. When the aquatic products need to be taken out, freezing is likely to occur between the placement frame 2 and the cold storage box 1, making it difficult to take out. At this time, the adjustment motor 15 is started, driving the active bevel gear 14 to rotate, and the active bevel gear 14 drives the driven bevel gear 13 to rotate, and the outer cylinder 11 rotates, so that the inner rod 12 moves up, and the inner rod 12 moves up to lift the placement frame 2, so that the placement frame 2 and the cold storage box 1 are separated.

[0028] Obviously, the invention described is only a part of the invention of the utility model, not the whole invention. Based on the invention in the utility model, all other inventions obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the utility model. The structures, devices and operating methods not specifically described and explained in the utility model shall be implemented according to the conventional means in the field unless otherwise specified and limited.
