Description

Technical Field

[0001] The present invention relates to the application field of refrigeration equipment, and specifically to a modular refrigeration device. Background Art

[0002] When a deep-sea manned platform carries out mission tasks such as pre-dive preparation, navigation, diving, and operation, a refrigeration storage environment is provided for refrigerating natural foods. A refrigeration device is a device used to lower the temperature and maintain a low-temperature environment, usually used to store food, medicine, or other items that need to be stored at low temperatures. When there is electricity, it is necessary to ensure an appropriate refrigeration temperature during the voyage period.

[0003] The working principle of the refrigeration device mainly relies on components such as a compressor cycle, an evaporator, and a condenser, and maintains a low-temperature environment through the physical changes of the refrigerant.

[0004] However, the equipment compartments of the offshore manned platform and the passages accessible to personnel are very narrow, and the underwater environment is relatively complex, with high requirements for earthquake resistance and anti-sway. As conventional devices such as freezers and refrigerators, it is difficult to enter the cabin as a whole, and it is difficult to work properly under a long-term large-angle tilt state, which will cause the stored fruits, vegetables, or medicines in the drawers of the refrigeration device to shake. This will not only produce collisions and make noises, affecting the concealment of the submarine, but also reduce the quality of the fruits and vegetables due to collisions. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a modular refrigeration device to solve the technical problems mentioned in the above background.

By providing two sets of limit buckles 1908 on the side of the second mounting plate 1906 that match the second guide rods 1904, when the height of the second mounting plate 1906 is adjusted, both ends thereof can be attached to the second guide rods 1904 through the limit buckles 1908, so that the heights of both ends of the second mounting plate 1906 can be balanced, and the second mounting plate 1906 is prevented from tilting only by being connected by the hooks 1909.

[0036] When the present invention is working specifically: when the refrigeration equipment in the first embodiment of the present application is assembled, mainly the refrigeration module 1, the rear back plate 3, the left side plate 4, the right side plate 5, the bottom plate 6, the middle partition 9, the hinge 10, the upper front door 11, the lower front door 12 and a plurality of drawers 16 are respectively transported to special scenarios such as ships or deep-sea manned platforms that need to enter through narrow channels. Among them, the refrigeration module 1 and the refrigeration unit 2 are shipped as a whole.

[0037] First, the rear back plate 3, the left side plate 4, the right side plate 5, the bottom plate 6, and the middle partition 9 are assembled and screwed and fixed using multiple sets of countersunk bolts 8 and M6 nuts spot-welded to their respective sides. Then, the refrigeration module 1 is engaged between the left side plate 4 and the right side plate 5 and is located on the top of the support frame 7. Multiple sets of countersunk bolts 8 are used again to reinforce with M6 threads spot-welded to the side of the top plate 101 to ensure that the air supply duct 13 and the return air duct 14 are docked with the centrifugal blower of the refrigeration unit 2. Next, hinges 10 are installed at the middle position of the top plate 101, the side of the right side plate 5, and the side of the bottom plate 6. Then, the upper front door 11 and the lower front door 12 are installed on the sides of the hinges 10. Finally, multiple sets of drawers 16 are engaged into the tops of multiple sets of guide rails 15.

[0038] When Example 2 in this application is working, when it is necessary to use the drawer 16 to store fruits, vegetables, and medicines, first pull the second mounting plate 1906 through the handle plate 1907 to elongate the flexible telescopic net 1905. Then, release the hook 1909 from the movable block 1911, place the fruits, vegetables, or medicines to be stored in the drawer 16, and then reinstall the hook 1909 into the movable block 1911. The limit buckles 1908 on both sides of the second mounting plate 1906 will fit against the outer wall of the second guide rod 1904, turn the knob 1915 to loosen it, that is, the inner wall of the knob 1915 moves away from the outer wall of the outer shell plate 1912. Then, pull the knob 1915 to make the whole movable block 1911 slide downward, driving the hook 1909, one end of the second mounting plate 1906, and the flexible telescopic net 1905 to slide downward synchronously. The limit buckle 1908 slides downward while fitting against the outer wall of the second guide rod 1904 until the flexible telescopic net 1905 tightly wraps the fruits, vegetables, or medicines. Then, reset and turn the knob 1915 so that the inner wall of the knob 1915 tightly fits against the outer wall of the outer shell plate 1912, thereby locking the position of the movable block 1911. When one end of the flexible telescopic net 1905 slides downward, depending on the amount of fruits and vegetables placed, the first mounting plate 1903 may be compressed by the spring 1902 and lift a short distance outside the first guide rod 1901. Due to the settings of the spring 1902 and the movable block 1911, both ends of the flexible telescopic net 1905 can press tightly on the fruits, vegetables, or medicines to prevent them from shaking, which is applicable to special scenarios where the hulls of ships, submarines, etc. are prone to tilting.
