Description

Technical Field

[0001] This invention relates to the field of greenhouse technology, specifically to a fish-vegetable integrated farming and overwintering greenhouse. Background Technology

[0002] Aquaponics greenhouses are a new type of integrated aquaculture and planting model that combines aquaculture and vegetable cultivation technologies to achieve scientific synergistic symbiosis. Currently, conventional symbiotic methods involve floating planting or separating the aquaculture water from the planting area. Floating planting uses floating bodies such as foam boards to directly fix vegetable seedlings onto floating planting boards for hydroponics. Although this method is simple, its utilization rate is low and it is only suitable for growing hydroponic vegetables. The method of separating aquaculture water and planting involves setting up fish farming areas and vegetable planting areas in the same greenhouse, using the water discharged from fish farming to irrigate the vegetable planting area. This model is relatively convenient and labor-saving. However, due to the high evaporation rate of water in the fish farming area, the humidity inside the greenhouse is relatively high, especially in the winter in northern regions. In order to maintain the temperature inside the greenhouse, ventilation is not advisable, resulting in very humid air inside the greenhouse. This has a significant impact on some vegetables that do not like humidity. For example, the suitable humidity range for the growth and development of fruits and vegetables such as eggplant, beans, watermelon, zucchini, and melon is 40% to 50%, while the humidity in aquaponics greenhouse is generally 80% to 95%, which is very unfavorable for the growth of fruits and vegetables. Moreover, excessive humidity can easily induce fungal and bacterial diseases. Summary of the Invention

[0003] In view of this, it is necessary to provide a fish-vegetable integrated farming and overwintering greenhouse that can isolate moisture in fish farming areas and regulate humidity in vegetable planting areas.

[0004] A greenhouse for aquaponics and winter cultivation includes a greenhouse constructed from gable walls, side walls, and a supporting frame. The greenhouse is equipped with a moisture isolation device that separates the greenhouse into a vegetable growing area and a fish farming area, preventing moisture from the fish farming area from entering the vegetable growing area. The moisture isolation device has closable vents, which are also equipped with dehumidifiers and ventilation fans. The ventilation fans facilitate air exchange between the vegetable growing area and the fish farming area, increasing the oxygen content in the fish farming area, while the dehumidifiers dehumidify the air flowing from the fish farming area into the vegetable growing area.

[0005] Preferably, the fish farming area is equipped with a fish pond and aquaculture water treatment device, and the vegetable planting area is equipped with a constant temperature maintenance device and an irrigation device.

The output end of the constant temperature maintenance device is connected to the water inlet of the fish pond, and the input end of the aquaculture water treatment device is connected to the drain outlet of the fish pond. The aquaculture water treatment device precipitates and separates the water discharged from the fish pond after aquaculture, and transports the separated clean water to the constant temperature maintenance device to regulate the soil temperature. The aquaculture water treatment device ferments the precipitated nutrient water containing fish excrement, and transports the fermented nutrient water to the irrigation device for irrigation. The constant temperature maintenance device guides the regulated clean water into the fish pond for recycling.

[0006] Preferably, the aquaculture water treatment device includes a vertical flow sedimentation tank, a fermentation tank, and a microbial treatment tank.

After aquaculture, the water is treated by sedimentation and separation in the vertical flow sedimentation tank. The separated clear water enters the microbial treatment tank for sterilization. The sterilized clear water enters the constant temperature holding device to regulate the soil temperature. The fertile water containing fish excrement after sedimentation in the vertical flow sedimentation tank enters the fermentation tank for fermentation. The fermentation tank transports the fermented fertile water to the irrigation device for irrigation.

[0007] Preferably, the constant temperature maintaining device includes a water storage tank, a constant temperature circulating water pipe, and a circulating pump. The water storage tank is located in the fish farming area or vegetable planting area. The constant temperature circulating water pipe is buried at intervals under the ground surface of the vegetable planting area. The drain outlet of the microbial treatment tank is connected to the inlet of the constant temperature circulating water pipe, the outlet of the constant temperature circulating water pipe is connected to the inlet of the water storage tank, and the outlet of the water storage tank is connected to the inlet of the fish pond. The circulating pump is installed on the constant temperature circulating water pipe. After aquaculture, separation, and sterilization, the clean water enters the constant temperature circulating water pipe and is transported to the vegetable planting area by the circulating pump to regulate the soil temperature and keep it constant before being transported back to the water storage tank for recycling.

[0008] Preferably, the constant temperature maintaining device further includes a constant temperature isolation water pipe. The greenhouse is also provided with a front wall, which is located at the front end of the greenhouse and opposite the gable wall. The constant temperature isolation water pipe is buried in the front wall. The inlet of the constant temperature isolation water pipe is connected to the outlet of the constant temperature circulating water pipe or the drain outlet of the microbial treatment tank. The outlet of the constant temperature isolation water pipe is connected to the inlet of the water storage tank. The clean water treated by the microbial treatment tank flows through the constant temperature isolation water pipe to insulate the front wall, and then flows into the water storage tank for recycling. Alternatively, the clean water treated by the microbial treatment tank first flows into the constant temperature circulating water pipe to regulate the soil temperature, and then flows into the constant temperature isolation water pipe from the constant temperature circulating water pipe to insulate the front wall, and then flows into the water storage tank for recycling.

[0009] Preferably, the constant temperature maintaining device further includes a circulating hot water storage pipe, which is buried in the gable wall of the greenhouse. The circulating hot water storage pipe is spaced apart along the length of the gable wall. The inlet of the circulating hot water storage pipe is connected to the outlet of the microbial treatment tank, and the outlet of the circulating hot water storage pipe is connected to the inlet of the constant temperature circulating water pipe. After separation and sterilization, the clean water enters the circulating hot water storage pipe for heat storage. The heat-stored clean water flows to the constant temperature circulating water pipe to regulate the soil temperature.

[0010] Preferably, a heat storage chamber is provided inside the gable wall, and the circulating hot water pipe passes through the heat storage chamber. The heat storage chamber is filled with heat storage blocks that are in contact with the surface of the circulating hot water pipe. A channel communicating with the heat storage chamber is opened on the inner side of the gable wall, and a heat storage fan is installed on the channel. The heat storage fan exhausts the hot air in the greenhouse into the heat storage chamber, and heat is stored through the heat storage blocks and the circulating hot water pipe.

[0011] Preferably, the water inlet of the water storage tank is also equipped with a microfilter, which is connected to an external tap water pipe and filters the water flowing into the water storage tank from the tap water pipe, the constant temperature circulating water pipe, or the constant temperature isolation water pipe.

[0012] Preferably, the outlet of the water storage tank is equipped with a water temperature heater to heat and regulate the temperature of the water flowing into the fish pond.

[0013] Preferably, the ventilation opening of the moisture isolation device is further provided with an air duct. The air inlet of the air duct is connected to the ventilation opening, and the air outlet of the air duct is located at the lower end of the water inlet of the fish pond. A diffuser is provided on the air outlet of the air duct. The diffuser is a cover with openings at the top and bottom. A grid plate is provided at the upper opening of the diffuser. The grid plate faces the water inlet of the fish pond. When the ventilation fan operates, it discharges the air from the vegetable planting area into the diffuser through the air duct. The water flowing into the fish pond from the constant temperature maintaining device is dispersed by the grid plate of the diffuser and then passes through the diffuser into the fish pond. During the process of passing through the diffuser, the water comes into contact with the air discharged from the air duct to increase the oxygen content of the water entering the fish pond.

[0014] The present invention adopts the above-mentioned technical solution, and its beneficial effects are as follows: By setting up a moisture isolation device in the vegetable planting area and the fish farming area, the moisture in the fish farming area can be isolated; by setting up a ventilation fan on the ventilation opening to disturb the air in the vegetable planting area and the fish farming area, the temperature between the vegetable planting area and the fish farming area can be balanced, so that they can exchange and circulate with each other, increase the convection of carbon dioxide and oxygen, increase the oxygen content of the air in the fish farming area, which is beneficial to the growth of fish; and by using a dehumidification device to dehumidify the air flowing to the vegetable planting area, the humidity in the vegetable planting area can be regulated, avoiding the impact of excessive humidity on the growth of fruits and vegetables in the vegetable planting area, and reducing the risk of inducing fungal, bacterial and other diseases in fruits and vegetables.

Detailed Implementation

[0021] To more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0022] Please refer to Figure 1 , Figure 2 and Figure 4 This invention provides a greenhouse for aquaponics and winter cultivation, comprising a greenhouse constructed from a gable wall 11, side walls 12, and a supporting frame 13. A moisture isolation device 14 is installed inside the greenhouse to separate a vegetable growing area 10 and a fish farming area 20, preventing moisture from the fish farming area 20 from entering the vegetable growing area 10. The moisture isolation device 14 has a closable ventilation opening 17, which is also equipped with a dehumidifier and a ventilation fan 18. The ventilation fan 18 facilitates air exchange between the vegetable growing area 10 and the fish farming area 20, increasing the oxygen content in the fish farming area 20, and the dehumidifier dehumidifies the air flowing from the fish farming area 20 into the vegetable growing area 10.

[0023] Specifically, the greenhouse is constructed by combining gable walls 11, side walls 12, and a supporting frame 13. The moisture isolation device 14 is a sealed wall or a sealed membrane, located in the middle of the greenhouse, in sealed contact with the ground, gable walls 11, and the membrane on the top of the greenhouse, thus isolating the greenhouse into a sealed vegetable planting area 10 and a fish farming area 20. The moisture isolation device 14 prevents humid air evaporated from the fish farming area 20 during the farming process from entering the vegetable planting area 10, thereby avoiding excessive humidity in the vegetable planting area 10. Ventilation openings 17 are provided on the moisture isolation device 14, located near the top of the device, with both ends of the openings connected to the vegetable planting area 10 and the fish farming area 20, respectively. In the aquaculture area 20, wind deflectors can be installed on the ventilation openings 17 to close or open them. At least two ventilation openings 17 are provided, each equipped with a ventilation fan 18. The ventilation fan 18 is an electric ventilation fan. At night, or when the oxygen content in the aquaculture area is low, the ventilation openings 17 can be opened and the ventilation fan 18 can be turned on. The ventilation fans 18 on the two ventilation openings 17 operate in opposite directions, disturbing the air in the vegetable growing area 10 and the fish farming area 20, balancing the temperature between them, promoting air exchange, increasing carbon dioxide and oxygen convection, and increasing the oxygen content in the fish farming area 20, which is beneficial for fish growth. In this embodiment, to prevent humid air from the fish farming area 20 from entering the vegetable growing area 10 during air exchange, a dehumidification device is also installed on each ventilation opening 17 to dehumidify the circulating air, reducing the amount of humid air entering the vegetable growing area 10. The dehumidification device can be a dehumidifier, non-woven fabric, desiccant pack, activated carbon, etc. During the day, when the humidity in the vegetable growing area 10 is high, the ventilation fan 18 can be turned on to exhaust the humid air from the vegetable growing area 10 into the fish farming area 20. The humid air in the fish farming area 20 is then dehumidified by the dehumidification device before entering the vegetable growing area 10, thus regulating the humidity of the vegetable growing area 10.

[0024] The fish farming area 20 is equipped with a fish pond 21 and a water treatment device 22. The water treatment device 22 is connected to the drain outlet of the fish pond 21. The water after farming is discharged into the water treatment device 22, where the fish excrement is settled and separated. The constant temperature device 15 is a heat-conducting pipe buried in the soil of the vegetable planting area 10 at intervals, at a depth of 40-50 cm from the ground surface. The irrigation device is laid on the planting ditch of the vegetable planting area 10. The output end of the water treatment device 22 is connected to the input ends of the constant temperature device 15 and the irrigation device through pipelines. The output end of the constant temperature device 15 is connected to the inlet of the fish pond 21, forming a loop. The aquaculture water treatment device 22 ferments the effluent containing fish excrement after sedimentation and separation, and then transports the fermented effluent to the irrigation device to irrigate the vegetables in the vegetable planting area 10 for nutrient supply. The aquaculture water treatment device 22 also transports the effluent after sedimentation and separation to the constant temperature holding device 15. The effluent flows along the constant temperature holding device 15. The water after aquaculture has a certain temperature. The aquaculture water is used to raise the temperature of the soil. The high specific heat capacity of water is used to regulate the soil temperature difference, so that the soil at the edge of the vegetable planting area and the soil in the middle can exchange heat, reduce the temperature difference between the soils, and keep the soil temperature constant. Finally, the water is introduced into the fish pond 21 for recycling.

[0025] Please refer to Figure 4 and Figure 5 Furthermore, the aquaculture water treatment device 22 includes a vertical flow sedimentation tank 221, a fermentation tank 223, and a microbial treatment tank 222. The inlet of the vertical flow sedimentation tank 221 is connected to the outlet of the fish pond 21, the overflow outlet of the vertical flow sedimentation tank 221 is connected to the inlet of the microbial treatment tank 222, the sedimentation outlet of the vertical flow sedimentation tank 221 is connected to the input end of the fermentation tank 223, the outlet of the microbial treatment tank 222 is connected to the inlet of the constant temperature holding device 15, and the input end of the irrigation device is connected to the output end of the fermentation tank 223. After aquaculture... The water is treated by sedimentation and separation in a vertical flow sedimentation tank 221. The separated clear water enters a microbial treatment tank 222. An ultraviolet sterilization device is installed on the microbial treatment tank 222 to sterilize the separated clear water. The sterilized clear water enters a constant temperature holding device 15 to regulate the soil temperature. The fertilizer water containing fish excrement, after sedimentation and separation in the vertical flow sedimentation tank 221, enters a fermentation tank 223 for fermentation. The fermentation tank 223 transports the fermented fertilizer water to an irrigation device for irrigation.

[0026] Please refer to Figure 3 and Figure 4Furthermore, the constant temperature maintaining device 15 includes a water storage tank 151, a constant temperature circulating water pipe 152, and a circulating pump 153. The water storage tank 151 is installed in the fish farming area 20 or the vegetable planting area 10. The constant temperature circulating water pipe 152 is a heat-conducting pipe, buried under the ground surface of the vegetable planting area 10, and arranged in parallel and at intervals. The drain outlet of the microbial treatment tank 222 is connected to the inlet of the constant temperature circulating water pipe 152. The outlet of the water tank is connected to the inlet of the water storage tank 151, and the outlet of the water storage tank 151 is connected to the inlet of the fish pond 21. The circulation pump 153 is installed on the constant temperature circulation water pipe 152. After breeding, separation and sterilization, the clean water enters the constant temperature circulation water pipe 152 and is transported to the vegetable planting area 10 by the circulation pump 153 to regulate the soil temperature in the vegetable planting area 10 and keep the soil temperature constant. Then it is transported to the water storage tank 151 for recycling.

[0027] Please refer to Figure 2 and Figure 3 Furthermore, the constant temperature maintaining device 15 also includes a constant temperature isolation water pipe 154. The greenhouse is also equipped with a front wall 16, which is located at the front end of the greenhouse and opposite to the gable wall 11. The constant temperature isolation water pipe 154 is a steel pipe with thermal conductivity plastic pipe, which is buried in the front wall 16. The inlet of the constant temperature isolation water pipe 154 is connected to the outlet of the constant temperature circulating water pipe 152, and the outlet of the constant temperature isolation water pipe 154 is connected to the inlet of the water storage tank 151. After the clean water in the constant temperature circulating water pipe 152 regulates the soil temperature, it flows through the constant temperature isolation water pipe 154 to heat up the front wall 16 to isolate the cold air from the outside, and then flows into the water storage tank 151 for recycling. In this embodiment, the inlet of the constant temperature isolation water pipe 154 can be directly connected to the outlet of the microbial treatment tank 222. The clean water treated by the microbial treatment tank 222 flows directly into the constant temperature isolation water pipe 154 to insulate the front wall 16, and then flows into the water storage tank for recycling. By using the aquaculture water to insulate the front wall 16, the cold air from the outside can be effectively blocked from entering the greenhouse through the front wall 16.

[0028] Please refer to Figure 3 and Figure 5Furthermore, the constant temperature maintaining device 15 also includes a circulating hot water storage pipe 155. The circulating hot water storage pipe 155 is a steel pipe with thermal conductivity plastic pipe, which is buried in the gable wall 11 of the greenhouse. The circulating hot water storage pipe 155 is spaced along the length of the gable wall 11. The inlet of the circulating hot water storage pipe 155 is connected to the outlet of the microbial treatment tank 222, and the outlet of the circulating hot water storage pipe 155 is connected to the inlet of the constant temperature circulating water pipe 152. After separation and sterilization, the clean water enters the circulating hot water storage pipe 155 to store heat. During the day, the temperature inside the greenhouse is relatively high, which can conduct heat to the gable wall 11. The clean water entering the circulating hot water storage pipe 155 after separation and sterilization can absorb the heat in the gable wall 11. At night, when the temperature inside the greenhouse is low, the clean water in the circulating hot water storage pipe 155 can be discharged into the constant temperature circulating water pipe 152 to regulate the temperature of the soil. In this embodiment, the circulating hot water pipe 155 and the constant temperature circulating water pipe 152 are controlled and managed by a three-way valve. When the aquaculture water temperature in the aquaculture area is higher than 15°C, the circulating hot water pipe 155 is closed, the water inside stops flowing, and heat is stored. The water in the fish pond 21 flows into the constant temperature circulating water pipe 152 through the microbial treatment tank 222 to regulate the soil temperature. When the aquaculture water temperature in the aquaculture area is lower than 15°C, the circulating hot water pipe 155 is open, the water in the fish pond 21 flows into the circulating hot water pipe 155 through the microbial treatment tank 222, and the water in the circulating hot water pipe 155, after heat storage, flows into the constant temperature circulating water pipe 152 to regulate the soil temperature.

[0029] Please refer to Figure 1 or Figure 4 Furthermore, the inlet of the water storage tank 151 is also equipped with a microfilter 156. The microfilter 156 is connected to an external tap water pipe, and water is supplied to the water storage tank 151 through the tap water pipe. The microfilter 156 is a screen filter that intercepts fine suspended matter and is used to filter the water flowing into the water storage tank 151 from the tap water pipe, the constant temperature circulating water pipe 152, or the constant temperature isolation water pipe 154.

[0030] Furthermore, the outlet of the water storage tank 151 is equipped with a water temperature heater, which is an electric heater. A water temperature sensor or a thermostat can be installed at the outlet of the water storage tank 151. The thermostat controls the water temperature heater to start, heating and regulating the water flowing into the fish pond 21 to prevent the water temperature in the fish pond 21 from being too low and affecting the farmed fish.

[0031] Please refer to Figure 4To improve the heat storage efficiency of the circulating hot water pipe 155, a heat storage chamber 111 is set inside the gable wall 11. The circulating hot water pipe 155 passes through the heat storage chamber 111, which is filled with heat storage blocks. The heat storage blocks are in contact with the surface of the circulating hot water pipe 155. A channel communicating with the heat storage chamber 111 is opened on the inner side of the gable wall 11. A heat storage fan 112 is installed on the channel. The heat storage fan 112 discharges hot air from the greenhouse into the heat storage chamber 111, where heat is stored through the heat storage blocks and the circulating hot water pipe 155. The heat storage block is a spherical block molded from heat storage materials such as industrial slag. It is difficult for adjacent heat storage blocks to fit together completely, forming a large number of irregularly distributed channels. When the temperature inside the greenhouse rises, the heat storage block quickly absorbs the heat inside the greenhouse and uses the heat storage principle of phase change materials to store the heat in the heat storage filler and transfer the heat to the pipe wall of the circulating hot water pipe 155. When the circulating hot water pipe 155 transfers heat to the constant temperature circulating water pipe 152, the heat storage block can supplement the temperature of the circulating hot water pipe 155.

[0032] Please refer to Figure 1 and Figure 4 To increase the oxygen content of the water in fish pond 21, an air duct 19 is installed on one of the vents 17 of the moisture isolation device 14. The air duct 19 is located within the fish farming area 20. The ventilation fan 18 on the vent 17 operates to transport air from the vegetable planting area 10 to the fish farming area 20. The air inlet of the air duct 19 is connected to the vent 17. The water inlet of the fish pond 21 is located above the fish pond 21, suspended in mid-air, at a certain distance from the water surface. The air outlet of the air duct 19 is located below the water inlet of the fish pond 21, close to the water surface. A diffuser is installed on the air outlet of the air duct 19. The ventilation hood 23 is an open-top and closed-bottom hood. A grid plate 24 is installed at the upper open end of the ventilation hood 23, directly opposite the water inlet of the fish pond 21. The ventilation fan 18 operates to exhaust air from the vegetable planting area 10 into the ventilation hood 23 through the air intake pipe 19. Water flowing from the water inlet enters the ventilation hood 23. As the water passes through the grid plate 24, it is blocked by the grid plate, forming scattered water droplets. These droplets pass through the ventilation hood 23 and fall into the fish pond 21. During their passage through the ventilation hood 23, they come into contact with the air exhausted from the air intake pipe 19, using the inertia of the water flow to carry the air into the water, thereby increasing the oxygen content of the water entering the fish pond. The grid plate 24, by blocking the water and forming scattered water droplets, increases the contact area between the water and air, thus increasing the dissolved oxygen content of the water.

[0033] This overwintering greenhouse has a two-way temperature regulation function for the vegetable planting area 10. In winter, the fish farming area 20 is a relatively closed environment. During the farming process, the water in the fish pond 21 can store heat, which is used to raise the temperature of the soil in the vegetable planting area 10. Utilizing the high specific heat capacity of water, the soil temperature difference is regulated, allowing heat exchange between the soil at the edges and in the center of the vegetable planting area 10, reducing the temperature difference between the soils and maintaining a constant soil temperature. In summer, the fish farming area 20 is open, and the water temperature is lower than the soil temperature in the vegetable planting area 10. Using the water in the fish pond 21 to cool and regulate the soil temperature in the vegetable planting area 10 is beneficial for vegetable growth.

[0034] The above-disclosed embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the invention. Those skilled in the art will understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present invention are still within the scope of the invention.

The aquaponics and overwintering greenhouse as described in claim 2, characterized in that: The water inlet of the water storage tank is also equipped with a microfilter, which is connected to an external tap water pipe. The microfilter filters the water flowing into the water storage tank from the tap water pipe, the constant temperature circulating water pipe, or the constant temperature isolation water pipe.

4. The aquaponics and overwintering greenhouse as described in claim 3, characterized in that: The water outlet of the storage tank is equipped with a water heater to heat and regulate the temperature of the water flowing into the fish pond.

5. The aquaponics and overwintering greenhouse as described in claim 1, characterized in that: The ventilation opening of the moisture isolation device is also equipped with an air duct. The air inlet of the air duct is connected to the ventilation opening, and the air outlet of the air duct is located at the lower end of the water inlet of the fish pond. A diffuser is installed on the air outlet of the air duct. The diffuser is a cover with openings at the top and bottom. A grid plate is installed at the upper opening of the diffuser. The grid plate faces the water inlet of the fish pond. When the ventilation fan operates, it discharges the air from the vegetable planting area into the diffuser through the air duct. The water flowing into the fish pond from the constant temperature device is dispersed by the grid plate of the diffuser and then passes through the diffuser into the fish pond. During the process of passing through the diffuser, the water comes into contact with the air discharged from the air duct to increase the oxygen content of the water entering the fish pond.
