Description

Technical Field

[0001] This utility model belongs to the field of cold storage technology, specifically relating to a cold storage cold storage for ships. Background Technology

[0002] The continued growth in maritime transport volume is accompanied by an increase in the number of maritime workers and cargo ships. Maritime transport cycles can range from several weeks to several months. The health and well-being needs of maritime workers on board have spurred the market for shipboard cold storage. Shipboard cold storage operates in a special environment, requiring high standards for equipment operational stability, corrosion resistance, and energy efficiency. The manufacturing processes and technological levels required are also high. Conventional cold storage facilities typically rely on mains electricity to ensure the normal operation of the refrigeration system and maintain the cold storage within a set temperature range.

[0003] In existing related technologies, some cold storage ice blocks are placed in the cold storage. They store cold when the refrigeration system is working normally and release the stored cold when the refrigeration system fails to work normally, so that the cold storage can still maintain the cold storage within the set temperature range for a period of time. However, items cannot be effectively moved or placed in the cold storage. Therefore, there is an urgent need to design a cold storage cold storage for ships to deal with these problems. Utility Model Content

[0011] Preferably, the cold storage assembly includes a condenser disposed inside the cold storage box, a compressor mounted on the condenser, an evaporator disposed between the condenser and the compressor, and a sealing platform mounted on the evaporator.

[0012] Preferably, a cold air fan is installed on the cold storage box.

[0013] The beneficial effects are:

[0014] This utility model discloses a cold storage warehouse for ships. Through an adjustable moving mechanism, a power assembly is activated to rotate a lead screw, driving a lifting platform mounted on the outer surface of the lead screw to move relative to and towards each other. Simultaneously, this moves the mounting platform and placement platform up and down. After the placement platform is adjusted, items are placed on it for refrigeration. Utilizing the cold storage capacity of the cold storage blocks, and with the auxiliary cold storage provided by the cold storage blocks within the placement platform, the freezing effect on the placement platform becomes more uniform and enhanced. This ensures the lifting and moving capability of the placement platform, while also increasing the cold storage capacity of the items on the platform. The large cold storage capacity extends the refrigeration and insulation time in the absence of power. It is convenient to use and highly practical. Attached Figure Description

[0027] In this embodiment: the adjusting and moving mechanism 2 includes an outer housing 201 fixedly mounted above the base 1, a top cover plate 202 fixedly mounted on the top of the outer housing 201, and double-opening end doors 203 mounted opposite each other on the front side of the outer housing 201. An inner housing 204 is installed inside the outer housing 201, and sealing boxes 2041 are vertically arranged on both sides of the inner housing 204. A lead screw 205 is vertically and parallelly arranged inside the sealing box 2041. A lifting platform 206 is mounted on the outer surface of the lead screw 205, and a power component is mounted on one end of the lead screw 205. A mounting platform 207 is provided on the lifting platform 206. A placement platform 208 is provided on the mounting platform 207, and a cold storage block 2081 is installed inside the placement platform 208. A cover plate 2082 is installed above the placement platform 208. Multiple shelves are provided inside the placement platform 208 for placing the cold storage block 2081. The built-in cold storage block 2081 can also play a role in cold storage when the refrigeration circuit is working normally, storing cold energy in the cold storage block 2081. When needed, such as in the event of power failure or refrigeration system failure, the cold storage block 2081 can also release the stored cold energy to extend the insulation time of the cold storage box, further extending the insulation time of the cold storage box. Buffer components are arranged longitudinally at equal intervals above the mounting platform 207. The power component includes a drive motor 2051 located on one side of the lead screw 205, and a belt 2052 is provided between the power end of the drive motor 2051 and one end of the lead screw 205. The buffer component includes a damping spring 209 located above the mounting platform 207, and a buffer platform 210 is installed on the damping spring 209. One end of the lead screw 205 has a forward-rotating thread on its outer surface, and the other end has a reverse-rotating thread on its outer surface. The lead screw 205 is connected to the lifting platform 206 via threads. The outer casing 201 is the cold storage casing. The cold storage material inside the cold storage block 2081 can be water, phase change material PCM, etc. An insulation layer is installed inside the outer casing 201. The outer casing 201 and the top cover plate 202 are fixedly and sealed together.

[0028] In this embodiment: the cold storage actuator 3 includes a housing 301 fixedly disposed inside the adjusting and moving mechanism 2. A water tank 302 is installed inside the housing 301. Cooling fins 3021 are provided on the outer surface of the water tank 302. A cold storage box 304 is disposed above the adjusting and moving mechanism 2. A cold storage component is disposed inside the cold storage box 304. The cold storage component includes a condenser 305 disposed inside the cold storage box 304. A compressor 306 is mounted on the condenser 305. An evaporator 308 is disposed between the condenser 305 and the compressor 306. A sealing platform 307 is mounted on the evaporator 308. A cold air blower 303 is disposed on the cold storage box 304. The evaporator 308 is located in the water tank 302. The condenser 305, compressor 306, and evaporator 308 are connected to form a refrigeration circuit. Preferably, there are multiple water tanks 302, distributed in multiple locations within the inner box 204. To improve the cold storage capacity and the uniformity of cold distribution, each water tank 302 can be equipped with its own refrigeration circuit, meaning each refrigeration circuit corresponds one-to-one with a water tank 302. The water tank 302 is a rectangular stainless steel tank with cooling ribs 3021 on at least one side, specifically the outer side, to enhance its strength and resist expansion and deformation caused by freezing of the water inside. The evaporator 308 is a coil type and can be positioned on the inner wall of the water tank 302 by pipe clamps. The compressor 306 is a DC compressor, eliminating the need for additional components such as expansion valves and capillary tubes. In addition to releasing the cold storage capacity from the water tank 302, the air cooler 303 can also be activated when necessary to provide cooling, further extending the insulation time of the cold storage.

[0029] Working principle: In use, the power unit is first activated to rotate the lead screw 205, which in turn drives the lifting platform 206 mounted on the outer surface of the lead screw 205 to move relative to and towards each other. Simultaneously, it drives the mounting platform 207 and the placement platform 208 to move up and down. After the placement platform 208 has been adjusted, items are placed on it. The categorization can be adjusted according to different usage needs, maximizing space utilization while categorizing frozen items. External power is then activated to power the compressor 306, and the evaporator 308 directly... The water in water tank 302 is cooled, creating an ice-water mixture. Since the evaporation temperature is generally below -5℃, the water in water tank 302 can be cooled to over 90% freezing point, resulting in a large cold storage capacity. When needed, the air cooler 303 delivers cold air into the inner box 204. After the inner box 204 is cooled, the material above the platform 208 is cooled by the thermal conductivity of the cold storage block 2081. This makes the freezing effect inside the inner box 204 more uniform and enhances the freezing efficiency.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
