Abstract
Description
Technical Field
[0001] This utility model relates to the field of shipborne graded refrigeration technology, and more specifically, to a shipborne graded refrigeration device. Background Technology
[0002] In the modern maritime transport sector, shipboard refrigeration units are key equipment for ensuring the freshness and quality of goods. Their performance directly affects the preservation status of goods during transportation. However, shipboard refrigeration units currently on the market generally suffer from a lack of flexibility in their cooling control systems. Their cold air delivery systems often adopt a uniform refrigeration method, which cannot make precise temperature-graded adjustments according to the specific needs of different types of goods and storage areas. This extensive refrigeration method not only affects refrigeration efficiency but may also lead to excessively low or high temperatures in some areas, failing to meet the precise temperature control requirements of different goods.
[0003] More importantly, the lack of tiered temperature control in this refrigeration system severely impacts operational convenience and cost-effectiveness in practical applications. Because it cannot independently regulate the temperature of different storage areas, operators struggle to optimize refrigeration solutions based on the characteristics of different goods. This not only increases energy consumption but may also affect the preservation quality of the goods. Furthermore, when loading goods with varying temperature requirements, the existing equipment cannot meet the needs of differentiated storage, significantly limiting the flexibility of ship transportation and potentially leading to the loss of some temperature-sensitive goods, resulting in unnecessary economic losses.

The refrigeration chamber 1 is equipped with an adjustment mechanism, which includes an air inlet pipe 2, a cooling inlet pipe 3, a speed control pipe 4, an air outlet mechanism, a central pipe 5, a contraction port 6, and a sealing mechanism. Multiple air inlet pipes 2 are provided, each connected to a portion of the refrigeration chamber 1. Each speed control pipe 4 is installed on an air inlet pipe 2. The central pipe 5 is installed on the speed control pipe 4. The cooling inlet pipe 3 is connected to multiple speed control pipes 4. Each central pipe 5 has a contraction port 6 installed within it. A rotary groove 7 is formed within the central pipe 5. The sealing mechanism is installed on the speed control pipe 4. Multiple rotary grooves 7 are arranged along the speed control pipe 4. Multiple entry grooves 8 are formed within the central pipe 5, connected to the rotary grooves 7. The sealing mechanism includes an outer sleeve 9 and adjusting bolts 10. Multiple outer sleeves 9 are provided with… Multiple external sleeves 9 are respectively installed on the speed regulating pipe 4. Each external sleeve 9 is threaded with an adjusting bolt 10. Each inlet groove 8 is provided with an abutting groove 11. The adjusting bolt 10 rests in the abutting groove 11. Each adjusting bolt 10 is provided with a sealing spring 12. Multiple sealing springs 12 are provided with a contact ring 13. The contact ring 13 is slidably connected to the adjusting bolt 10 and abuts against the external sleeve 9.

[0031] In this embodiment, cold air needs to be introduced during freezing. Different spaces require different freezing effects, so only the air intake needs to be controlled. First, the cold air is introduced into the central pipe 5 through the speed regulating pipe 4. The cold air is first diverted by the contraction port 6. After passing through the outer wall of the contraction port 6, it flows into the rotary groove 7 along the inlet groove 8. The multiple rotary grooves 7 cause this part of the cold air to rotate and flow in the opposite direction to the cold air entering through the contraction port 6. This greatly increases the flow resistance of the contraction port 6, thereby greatly reducing the flow velocity and thus reducing the cooling effect. When it is necessary to change the flow velocity, it is only necessary to stop the flow in the rotary grooves 7. Therefore, it is only necessary to press the corresponding adjusting bolt 10 against the abutment groove 11 to seal the corresponding abutment groove 11. Then, the number of flowable rotary grooves 7 is changed, thereby reducing the backflow resistance and completing the adjustment process.
[0032] More specifically, by controlling the air intake volume of different air intake pipes 2, the freezer 1 can be adjusted in stages, thus adapting to different requirements and completing the usage process.
[0033] In summary, during the use or operation of the overall equipment: When freezing, appropriate cold air needs to be introduced. Different spaces require different freezing effects, so only the air intake needs to be controlled. First, the cold air enters the central pipe 5 through the speed regulating pipe 4. The incoming cold air is first diverted by the contraction port 6, then flows along the inlet groove 8 into the rotary groove 7 through the outer wall of the contraction port 6. Multiple rotary grooves 7 cause this portion of the cold air to rotate and flow in the opposite direction to the cold air entering through the contraction port 6, greatly increasing the flow resistance at the contraction port 6 and significantly reducing the flow velocity, thus reducing the cooling effect. When it is necessary to change the flow velocity, simply stop the flow in the rotary grooves 7. Therefore, simply press the corresponding adjusting bolt 10 against the contact groove 11 to seal it, thus changing the number of flowable rotary grooves 7, thereby reducing the backflow resistance and completing the adjustment process. By controlling the air intake of different air intake pipes 2, the freezing chamber 1 can be adjusted in stages, thus adapting to different requirements and completing the usage process.
