Description

Technical Field

[0001] This invention relates to the field of aquaculture technology, and in particular to a method for heating aquaculture ponds using the heat storage capacity of a double-layered greenhouse. Background Technology

[0002] The booming development of aquaculture has greatly satisfied the global demand for aquatic products. However, its production process, especially in temperate and cold regions, has always faced a key bottleneck—the seasonality and diurnal fluctuations of water temperature. The optimal growth, reproduction, and immune response of many high-value farmed species (such as shrimp, grouper, largemouth bass, and eel) are highly dependent on a specific and relatively stable water temperature range (usually 20℃-30℃). When the water temperature falls below their tolerance threshold, it leads to reduced feeding, stunted growth, metabolic disorders, decreased immunity, high disease incidence, and even large-scale mortality, causing huge economic losses. Traditional open-air ponds or simple single-layer greenhouse farming methods are constrained by environmental temperature changes, making it difficult to maintain water temperature during winter and cold nights, severely restricting production cycles, farming density, and geographical expansion. Therefore, developing efficient, reliable, and low-cost water heating and insulation technologies is the core foundation for achieving high-yield, stable, efficient, and sustainable development in aquaculture, and has significant practical implications for enhancing industry competitiveness and ensuring food safety.

[0003] Modern facility agriculture widely adopts plastic greenhouse (solar greenhouse, multi-span greenhouse) technology. Its core lies in utilizing the high transmittance (70%-90%) of short-wave solar radiation by plastic film (or PC board, glass) and the low transmittance of long-wave solar radiation from the ground, effectively accumulating solar energy during the day. However, conventional single-layer greenhouses have significant drawbacks: poor heat insulation. The total thermal resistance (R value) of a single-layer covering material is very low, and heat loss mainly occurs through conduction, convection, and radiation. At night, driven by the huge temperature difference between the inside and outside, the heat accumulated during the day is rapidly dissipated into the cold environment. Especially on clear, windless nights, a significant "temperature inversion" phenomenon (cold air sinking from the roof) can even occur inside the greenhouse. This leads to drastic diurnal temperature fluctuations in the air and water temperatures inside the greenhouse. Single-layer structures mainly rely on the air inside the greenhouse for heating, but the air volumetric heat capacity is small, resulting in extremely limited heat storage capacity. The small amount of heat absorbed by the ground surface and structures is also insufficient due to its inadequate heat storage capacity and poor thermal conductivity, making it difficult to generate sufficient and stable residual heat release at night to offset the heat loss. The biggest problem with aquaculture greenhouses is their disconnect from water heating. Even on sunny days, while ordinary greenhouses can significantly raise the air temperature, the accumulated heat mainly remains in the air and shallow surface, lacking an effective mechanism to quickly and substantially transfer the excess daytime air heat to the water for storage (air has poor thermal conductivity, resulting in low and slow natural convection heat transfer). Conversely, when the air inside the greenhouse cools rapidly at night due to poor insulation, the water becomes a source of heat loss (convection + radiation), making it difficult to obtain effective insulation or heat replenishment from the greenhouse structure. Therefore, traditional single-layer greenhouses are essentially "weak insulators," not "water-based heat storage / heaters," and lack a mechanism for actively storing and releasing heat using their own structure.

[0004] To address the aforementioned problems, this invention proposes a method for heating aquaculture ponds using the heat storage capacity of a double-layered greenhouse. Summary of the Invention

[0005] Given that heating requires a significant amount of energy, existing aquaculture greenhouses only offer insulation and have limited heat collection and storage capabilities, raising the temperature during cold seasons demands substantial energy. This not only increases aquaculture costs but also puts pressure on energy supply. Furthermore, traditional heating methods are often inefficient, resulting in significant heat loss and failing to fully utilize energy to effectively raise water temperature. This makes it difficult to meet the stable and suitable water temperature requirements of aquaculture ponds during cold seasons, thus affecting the growth rate and quality of aquatic products. Therefore, this invention proposes a method for heating aquaculture ponds using the heat storage capacity of a double-layered greenhouse.

[0006] This invention proposes a method for heating aquaculture ponds using the heat storage capacity of a double-layer greenhouse. The method includes a heat exchange box, a connecting frame bolted to the right side of the heat exchange box, an air pump bolted to the top of the connecting frame, an air inlet connected to an air box via a pipe, the top of the air box bolted to the bottom of the heat exchange box, an outlet penetrating a hole at the bottom of the heat exchange box and connected to a one-way nozzle, the bottom of the one-way nozzle bolted to the bottom of the interior of the heat exchange box, an interlayer connected to the air pump via a pipe, the interlayer being composed of two layers of greenhouse film from the double-layer greenhouse, an outlet at the top of the heat exchange box connected to the interior of the interlayer via a pipe, a circulation pump bolted to the top of the heat exchange box, an inlet connected to the interior of the heat exchange box, a power mechanism bolted inside the connecting frame, a dispersing mechanism bolted to the shaft of the power mechanism, and a water filtration mechanism bolted to the surface of the dispersing mechanism. The specific steps for heating aquaculture ponds are as follows: S1: The breeding pond is built inside a double-layered greenhouse. The doors and windows of the double-layered greenhouse are designed with heat-insulating materials and structures. Carbon dioxide is injected into the interlayer of the double-layered greenhouse and air is extracted to fill the interlayer with carbon dioxide. The interlayer is equipped with carbon dioxide replenishment pipes and discharge valves, and the amount of carbon dioxide is monitored at all times. When the amount of carbon dioxide decreases, it must be replenished in time. When the sun shines on the double-layered greenhouse, the carbon dioxide in the interlayer absorbs heat due to the greenhouse effect, causing the temperature of the carbon dioxide in the interlayer to rise. When the room temperature is found to be too high, some carbon dioxide is discharged in time. S2: Lay a heating pipe network at the bottom of the breeding pond, connect one end of the heating pipe network to the inlet of the circulating pump, and connect the outlet of the heat exchange box to the breeding pond through a pipe. S3: The circulating pump draws cold water from the breeding pond through the heating pipe network and injects it into the heat exchange box. The air pump pumps the hot air from the double-layer greenhouse into the air box. The air box disperses the hot air into the heat exchange box through a one-way air nozzle. After the hot air enters the water, it is in the form of bubbles. The heat inside the hot air is absorbed by the water, thereby heating the water in the heat exchange box. S4: The heat-absorbing gas continues to move upward and is discharged back into the interlayer of the double-layer greenhouse through the pipe; S5: The water heated inside the heat exchanger is drained back into the aquaculture tank, where it transfers heat to the aquaculture tank, thus heating the water in the tank.

[0016] The beneficial effects of this invention are: By filling the double-layered greenhouse with carbon dioxide to absorb solar energy through the greenhouse effect, the solar energy is then stored as heat energy. The hot air is directly introduced into the water in the heat exchange box, allowing the water to directly absorb the heat from the hot air. The heated water can then be circulated back into the aquaculture pond to heat the water inside the pond. There is no need to worry about the temperature being too high and changing the water's structural composition, nor is there a need to burn energy for heating. Only electricity needs to be supplied to the geared motor, air pump, and circulation pump. Attached Figure Description

The specific steps for heating aquaculture ponds are as follows: S1: The breeding pond is built inside a double-layer greenhouse. The doors and windows of the double-layer greenhouse are designed with heat-insulating materials and structures. Carbon dioxide is injected into the interlayer 9 of the double-layer greenhouse and air is extracted to fill the interlayer 9 with carbon dioxide. Pipes for replenishing carbon dioxide and discharge valves are installed on the interlayer 9, and the amount of carbon dioxide is monitored at all times. When the amount of carbon dioxide decreases, it must be replenished in time. After the sun shines on the double-layer greenhouse, the carbon dioxide in the interlayer 9 absorbs heat due to the greenhouse effect, causing the temperature of the carbon dioxide in the interlayer 9 to rise. When the room temperature is found to be too high, some carbon dioxide is discharged in time. S2: Lay a heating pipe network at the bottom of the breeding pond, connect one end of the heating pipe network to the inlet of the circulating pump 10, and connect the outlet of the heat exchange box 1 to the breeding pond through a pipe. S3: The circulating pump 10 draws cold water from the breeding pond through the heating pipe network and injects it into the heat exchange box 1.

After the hot air enters the water, it is in the form of bubbles. The heat inside the hot air is absorbed by the water, thereby heating the water in the heat exchange box 1. S4: The heat-absorbing gas continues to move upward and is discharged back into the interlayer 9 of the double-layer greenhouse through the pipe; S5: The water heated inside the heat exchange box 1 is discharged back into the breeding pond, transferring heat to the breeding pond to heat the water in the breeding pond.

[0021] Gear-like structures can be made of self-lubricating, rust-proof, and wear-resistant materials, allowing them to operate underwater.

[0022] Working principle: After connecting the pipeline, the carbon dioxide in the interlayer 9 absorbs sunlight through the greenhouse effect and is converted into heat energy, forming hot air. The pump 6 is powered and draws the hot air from the interlayer 9 through the pipeline, pumping it into the air box 7. The air box 7 then guides the hot air into the one-way nozzle 8. The one-way nozzle 8 has a one-way structure; water enters the one-way nozzle 8, which disperses the hot air into small bubbles and discharges them into the water. The power to the reduction motor 21 is then connected. The reduction motor 21 drives the worm gear 22 to rotate, which in turn drives the worm wheel 23 to rotate clockwise. The worm wheel 23 drives the large rotating wheel 24 to rotate clockwise, which in turn drives the transmission belt 25 to rotate. The two guide wheels 26 can... The transmission belt 25 guides the right side of the large rotating wheel 24 backward, ultimately connecting the transmission belt 25 to the driven wheel 27. This allows the transmission belt 25 to drive the driven wheel 27 to rotate, which in turn drives the rotating rod 31 to rotate. The rotating rod 31 is rotatably connected to the heat exchange box 1 via bearings, ensuring smooth rotation. The rotating rod 31 drives four large helical gears 32 to rotate. Both the large and small helical gears 32 and 33 are helical gears, allowing the large helical gears 32 to mesh with the small helical gears 33, facilitating their rotation. The small helical gears 33 then drive the rotating shaft 34 to rotate, which is also rotatably connected to the heat exchange box 1 via bearings. The rotating shaft 34 can rotate smoothly, driving the spiral blades 35 to rotate. The spiral blades 35 can agitate the water, ensuring even distribution and maximizing heat absorption. The rotating shaft 34 can also drive the large gear 36 to rotate. The top of the gear rod 37 has a gear structure, allowing it to mesh with the large gear 36. The large gear 36 can then drive both gear rods 37 to rotate. The gear rods 37 are connected to the heat exchange box 1 via bearings, ensuring smooth rotation. The gear rods 37 can also quickly drive the cutting blade 38 to rotate, cutting the bubbles to make them smaller. Simultaneously, the rotating rod 31 can drive the main conical gear 41 to rotate. Gear 41 drives the secondary bevel gear 42 to rotate, which in turn drives the rotating rod 43 to rotate. The rotating rod 43 is connected to the heat exchange box 1 via bearings, allowing it to rotate smoothly. The rotating rod 43 drives the filter plate 44 to rotate, which filters the gas after heat absorption. The filtered water and water vapor are blocked by the filter plate 44, which then throws the water out by rotating.
