Description

Technical Field

[0001] The present invention relates to the technical field of ships, and in particular to a hydroponic vegetable planting cabin for ships and an ocean-going polar ship. Background Art

[0002] Ocean-going polar ships refer to special ships that can sail in polar ice areas such as the Arctic and Antarctic. Due to the special polar environment and sparse ports, ocean-going polar ships need to have ultra-long supply cycles. Food is mainly storable materials (such as canned food and compressed food), and is equipped with refrigerated cabins (-18℃~0℃) to store fresh fruits and vegetables.

[0003] For ocean-going polar vessels with long voyages and no mid-journey replenishment, the demand for fresh vegetables is particularly important. Currently, ships often use vegetable storage inside the hull to store vegetables. However, even in vegetable storages equipped with ethylene removal devices and ozone generators at suitable temperatures, the maximum shelf life for vegetables is only 1-2 months. This short shelf life of vegetables is far from meeting the demand for fresh vegetables for ships sailing in polar regions with a voyage period of more than half a year. In addition, in order to ensure the freshness of vegetables as much as possible and avoid rotting, only vegetables with longer storage cycles, such as potatoes and radishes, can be used, resulting in a limited variety of vegetables.

[0004] Therefore, there is an urgent need for a hydroponic vegetable growing cabin for ships and an ocean-going polar ship to solve the above problems. Summary of the Invention

[0034] Ocean-going polar ships refer to special ships that can sail in polar ice areas such as the Arctic and Antarctic. Due to the special polar environment and sparse ports, ocean-going polar ships need to have ultra-long supply cycles. Food is mainly storable materials (such as canned food and compressed food), and is equipped with refrigerated cabins (-18℃~0℃) to store fresh fruits and vegetables.

[0035] For ocean-going polar vessels with long voyages and no mid-journey replenishment, the demand for fresh vegetables is particularly important. Currently, ships often use vegetable storage inside the hull to store vegetables. However, even in vegetable storages equipped with ethylene removal devices and ozone generators at suitable temperatures, the maximum shelf life for vegetables is only 1-2 months. This short shelf life of vegetables is far from meeting the demand for fresh vegetables for ships sailing in polar regions with a voyage period of more than half a year. In addition, in order to ensure the freshness of vegetables as much as possible and avoid rotting, only vegetables with longer storage cycles, such as potatoes and radishes, can be used, resulting in a limited variety of vegetables.

[0036] Therefore, in order to ensure the demand for fresh vegetables during long-term voyages and increase the variety of vegetables supplied, this embodiment provides a hydroponic vegetable planting cabin for a ship.

[0037] like Figures 1 to 3As shown, the hydroponic vegetable planting cabin for ships is arranged on the side of the hull and close to the waterline of the hull. The hydroponic vegetable planting cabin for ships is also provided with portholes for natural light to enter. The hydroponic vegetable planting cabin for ships includes a cultivation system 1, a nutrient solution circulation system 2 and an air-conditioning system. The cultivation system 1 includes a plurality of cultivation pipes 11, each of which is provided with a plurality of planting holes 111 for cultivating vegetables. The nutrient solution circulation system 2 includes a nutrient solution storage tank 21, a circulation pipe 22 and a pump 23. The circulation pipe 22 is used to connect the nutrient solution storage tank 21 and the cultivation pipe 11. The pump 23 is used to drive the flow of nutrient solution. The air-conditioning system is used to control the temperature and humidity in the hydroponic vegetable planting cabin for ships.

[0038] By setting up a hydroponic vegetable planting cabin for ships composed of a cultivation system 1, a nutrient solution circulation system 2 and an air-conditioning system, vegetables can be grown hydroponically in the hull, thereby increasing the supply of fresh vegetables on the ship, ensuring the demand for fresh vegetables during long-term voyages, and increasing the variety of vegetable supply. On the one hand, the hydroponic vegetable planting cabin is set close to the waterline of the hull to keep the hydroponic vegetable planting cabin as stable as possible. On the other hand, the hydroponic vegetable planting cabin is set on the side of the hull, and the portholes opened on the side are used to ensure the entry of natural light, thereby providing a stable and well-lit cultivation environment for the growth of vegetables.

[0039] In this embodiment, the hydroponic vegetable planting cabin for ships is divided into two cabins, one is the planting and cultivation cabin 100, and the other is the planting control cabin 200 for controlling the temperature, humidity and other environmental conditions of the planting and cultivation cabin 100, wherein the control system for the air-conditioning system and the control system for the nutrient solution circulation system 2 are both located in the planting control cabin 200.

[0040] The cultivation pipe 11 is arranged in the planting and cultivation cabin 100, and in order to enable the cultivation pipe 11 used for cultivating vegetables to better receive natural light entering through the porthole, the cultivation pipe 11 is usually placed on the side, that is, the length direction of the cultivation pipe 11 is parallel to the central axis of the hull, so as to make full use of the ambient light to photosynthesize the vegetables and promote the growth of vegetables.

[0041] Among them, in order to facilitate the storage and utilization of vegetables after planting, the hydroponic vegetable planting cabin for the ship is set near the cold storage area to ensure smooth use. The cold storage area includes a first freezer 300 for storing meat, a second freezer 400 for storing fish, and a cold storage room 500 for storing vegetables.

[0042] It's important to note that hydroponic vegetables are those whose roots primarily grow within a nutrient solution layer, relying solely on the solution for water, nutrients, and oxygen. Unlike vegetables grown in traditional soil cultivation, hydroponic vegetables boast short growth cycles, high yields, and simple technology. Therefore, hydroponic vegetables are grown under relatively controlled environmental conditions, allowing for precise regulation of nutrient supply and various environmental factors. As long as there's ample light and optimal humidity and room temperature, the vegetables will thrive. Therefore, as long as the input conditions are met, hydroponic vegetable cultivation on ships is feasible.

[0043] In addition, hydroponic vegetable cultivation methods mainly include trough and pipeline types. The pipeline hydroponic cultivation method uses pipelines as the primary cultivation method, utilizing the interconnected pipelines to achieve circulation and control of the nutrient solution. Furthermore, the roots are protected within the pipelines, maximizing nutrient absorption and preventing insect infestation. In this embodiment, the pipeline hydroponic cultivation method adopted not only has the above advantages, but also minimizes splashing and loss of nutrient solution during the rocking of the ship, where wind and waves at sea can significantly impact the vessel during navigation.

[0044] Optionally, the cultivation system 1 includes a carrying frame 12, a plurality of cultivation pipes 11 are connected to the carrying frame 12 and are distributed at intervals along the height direction, and the carrying frame 12 is connected to the hull.

[0045] A plurality of cultivation pipes 11 for cultivating vegetables are distributed on the supporting frame 12 at intervals along the height direction to form a shelf structure. The vertically stacked structure can improve space utilization, thereby increasing the amount of cultivated vegetables.

[0046] In this embodiment, the cultivation pipes 11 are mostly made of PVC-U or PP plastic pipes, and the distance between two adjacent cultivation pipes 11 needs to meet the height requirements of vegetable growth.

[0047] Optionally, the cultivation system 1 further includes fill lights 13 corresponding one-to-one to the plurality of cultivation pipes 11 , and the fill lights 13 are connected to the supporting frame 12 .

[0048] Since the sunlight absorbed through the portholes is limited and cannot meet all the lighting conditions required for vegetable growth, a fill light 13 is provided on the supporting frame 12 to supplement the lack of light. The combination of natural light and the fill light 13 can achieve an ideal growth state for the vegetables.

[0049] In this embodiment, the power of the fill light 13 can be freely adjusted according to the growth pattern of the plant itself, weather changes, and lighting time, so as to ensure the lighting requirements during the growth of vegetables.

[0050] Optionally, the spacing dimension L between the plurality of planting holes 111 satisfies 25 cm ≤ L ≤ 30 cm. By limiting the spacing dimension L between the plurality of planting holes 111 to satisfy 25 cm ≤ L ≤ 30 cm, on the one hand, it is possible to avoid the spacing between the planting holes 111 being too small, thereby causing interference between two adjacent vegetables during growth, and on the other hand, it is possible to avoid the spacing being too large, thereby causing waste of space.

[0051] Optionally, the inner wall of the cultivation pipe 11 is provided with a black coating. This coating can, on the one hand, block light, simulate a dark environment, and inhibit algae growth, thereby preventing the growth of green algae, as green algae can rapidly multiply in ordinary transparent pipes, contaminating the nutrient solution, affecting crop growth, and even causing crop death. Furthermore, the black inner wall reflects infrared and other light, providing insulation and reducing pipe temperature fluctuations. This ensures that the nutrient solution maintains a suitable temperature and fluidity within the pipe, promoting normal crop growth.

[0052] Optionally, the circulation pipe 22 includes a liquid supply pipe 221, a liquid return pipe 222, and a connecting pipe 223. The connecting pipe 223 is used to connect multiple cultivation pipes 11 in series. The liquid supply pipe 221 is used to connect the nutrient solution storage tank 21 and the cultivation pipe 11 at the beginning, and the liquid return pipe 222 is used to connect the cultivation pipe 11 at the end and the nutrient solution storage tank 21. By utilizing the liquid supply pipe 221, the liquid return pipe 222, and the connecting pipe 223, the nutrient solution circulates between the nutrient solution storage tank 21 and the cultivation pipe 11, so that the nutrient solution can be recycled and waste is avoided.

[0053] Optionally, the temperature of the hydroponic vegetable growing cabin for the ship is T, and satisfies 10° C. ≤ T ≤ 25° C. By limiting the temperature T of the hydroponic vegetable growing cabin for the ship to satisfy 10° C. ≤ T ≤ 25° C., it is ensured that the vegetables are grown in a suitable temperature environment.

[0054] In this embodiment, temperature control primarily relies on the ship's air conditioning system, with the heat pump unit serving as the core device for both cooling and heating. Based on the reverse Carnot cycle principle, it regulates indoor temperature by consuming a small amount of electrical energy to transport heat, offering both high efficiency, energy saving, and bidirectional temperature control. During operation, in cooling mode, the compressor compresses the gaseous refrigerant, releasing heat and liquefying it in the condenser. The liquid refrigerant, after being depressurized and cooled by the expansion valve, absorbs heat and vaporizes in the evaporator. The vaporized refrigerant is then drawn back into the compressor for circulation. In heating mode, the refrigerant flow is redirected by a four-way reversing valve. A heat pump unit typically consists of a compressor, condenser, evaporator, expansion valve, four-way reversing valve, refrigerant, and an electronic control system. These components work together to regulate the indoor temperature with minimal energy consumption. Since air conditioning systems are conventional technology in the marine industry, they will not be discussed in detail here.

[0055] In addition, the hydroponic vegetable growing cabin for ships also includes a ventilation system that complements the air-conditioning system. The ventilation system is used to control the circulation flow of air in the hydroponic vegetable growing cabin for ships.

[0056] Furthermore, the daytime temperature of the hydroponic vegetable growing cabin used for the ship is T1, and satisfies 15°C≤T1≤25°C.

[0057] Among them, when the temperature is lower than 15℃, the growth of vegetables will slow down, and when it is higher than 30℃, they will grow poorly. Since the temperature difference between day and night is large during sailing at sea, and the photosynthesis of vegetables is most intense during the day, the temperature needs to be further optimized. By limiting the daytime temperature T1 of the hydroponic vegetable planting cabin used for ships to meet 15℃≤T1≤25℃, it is ensured that during the day, the vegetables are in a suitable growth environment temperature.

[0058] Furthermore, the temperature of the hydroponic vegetable growing cabin for ships during the night is T2, and satisfies 10°C ≤ T2 ≤ 15°C. By limiting the temperature T2 of the hydroponic vegetable growing cabin for ships during the night to 10°C ≤ T2 ≤ 15°C, respiration is suppressed, which is conducive to the accumulation of organic matter.

[0059] In this embodiment, a polar ocean vessel is provided, comprising the aforementioned hydroponic vegetable growing chamber. By utilizing the aforementioned hydroponic vegetable growing chamber, the polar ocean vessel can obtain a rich variety of fresh vegetables even during long voyages. This not only ensures the health of the crew but also helps reduce the size of traditional vegetable cold storage, saving space and thus optimizing the internal cabin layout of the vessel.

[0060] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
