Description

Technical Field

[0001] This invention relates to an energy-saving three-dimensional insect breeding system and method, belonging to the field of insect breeding equipment. Background Technology

[0002] Three-dimensional insect farming is a highly efficient method of insect breeding. Through multi-layered vertical arrangement, it effectively utilizes space, solving the problems of large land area and high cost associated with traditional ground-based farming. Insect rearing requires suitable temperature and humidity; therefore, ventilation and heat exchange are crucial components of three-dimensional insect farming equipment. Patent publication number CN 117016495 A discloses a method and apparatus for raising corrosive insect larvae using natural ventilation and supplemental lighting. Its specific structure includes: a sealed insect farming device with several farming layers. Each farming layer includes a bottom support mechanism and surrounding baffles. The baffles are perforated and breathable, and a sealing mechanism is provided around each baffle. This sealing mechanism can be opened or closed depending on the actual farming environment. Based on the phototaxis of black soldier fly larvae, this invention allows for alternating periods of light and darkness during larval rearing, according to environmental requirements. During periods of light exposure, the larvae move downwards from the surface of the culture medium to avoid the light. When there is no light, the larvae return to the surface, creating small pores that allow for ventilation. This not only loosens the culture medium, preventing it from clumping, but also facilitates ventilation and heat dissipation, effectively preventing the culture medium from deteriorating. However, the following problems exist: (1) The gas inlet and outlet positions are not much different. The air in the same breeding layer flows horizontally. The gas flows a long distance and the wind pressure drops significantly, resulting in a general ventilation and heat exchange effect. A high-power fan is required to achieve a good ventilation and heat exchange effect, resulting in high energy consumption; (2) During the breeding process, the ventilation volume of different breeding layers is different due to the different distances from the fan, resulting in uneven ventilation; (3) This invention belongs to the integrated breeding and drying platform. During the drying process, the gas flow direction cannot be flexibly adjusted, resulting in low drying efficiency and high energy consumption. Summary of the Invention

[0039] Furthermore, preferably: the water heating mechanism is installed at intervals at the bottom of the breeding structure or the water heating mechanism is installed at the bottom of the lowest layer of the breeding structure.

[0040] This invention also provides an energy-saving method for drying insects during breeding, using the energy-saving three-dimensional insect breeding system of this invention, including the following steps:

[0041] (1) Place the insect feed and larvae on the conveyor net, and then seal the breeding platform;

[0042] (2) When the temperature is low, adjust the air inlet and outlet adjustment mechanism to the fully sealed area, the water heating mechanism will heat up, and the heat will flow from bottom to top, quickly raising the temperature inside the entire breeding platform to the suitable breeding temperature.

[0043] (3) Adjust the air inlet and outlet adjustment mechanism to the fully open area. Adjust the opening degree and time of the air outlet valve and air inlet valve according to the ambient temperature and humidity and the temperature and humidity inside the breeding platform. The air is automatically drawn into the breeding platform under the action of the pressure difference between the inlet and outlet. The air flows in the transverse ventilation duct of each layer of the breeding mechanism to keep the breeding platform with suitable temperature and humidity.

[0046] Furthermore, preferably, in step (4), the air drying process is carried out using intermittent negative pressure ventilation.

[0047] The beneficial effects of this invention are:

[0048] In this invention, the air outlet duct is located at the top of the multi-layered aquaculture platform, and its position is higher than the platform itself. This structure creates a height difference between the air outlet duct and the air inlet duct. With this structure, heat is generated during insect rearing, causing the internal temperature of the platform to consistently exceed the external temperature. The difference in density between the hot air at the outlet duct and the cold air at the inlet duct creates buoyancy and pressure, resulting in natural air circulation within and around the multi-layered aquaculture platform. This effectively improves ventilation efficiency and reduces energy consumption.

[0049] Meanwhile, existing traditional ventilation systems in multi-level aquaculture platforms use ducts to ventilate from one end of the platform to the other. The length-to-width ratio of these platforms is typically 4-10, resulting in long airflow distances and significant pressure losses. This invention utilizes transverse ventilation ducts between the aquaculture platforms, significantly shortening the airflow distance compared to the traditional longitudinal duct system. This effectively reduces pressure loss and improves ventilation efficiency.

[0050] The combination of natural ventilation device and energy-saving air conditioning device in this invention can conveniently and quickly change the air intake position and air volume in the breeding platform, realizing the conversion of ventilation, heat exchange and air drying operations in the breeding platform. Compared with the prior art, it has a simple structure and is easy to operate. Attached Figure Description

Detailed Implementation

[0078] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0079] Example 1

[0080] like Figure 1 and 2 As shown, an energy-saving three-dimensional insect breeding system includes a main frame 4, several layers of breeding structures 3 set on the main frame 4, a top plate 6, a bottom plate 11, a natural ventilation device and an energy-saving air conditioning device, and a transverse ventilation duct 8 is provided between two adjacent layers of breeding structures 3.

[0081] The natural ventilation device is a device that uses the heat generated during the insect breeding process to create a pressure difference between the air inlet 1-1 and the air outlet, thereby enabling air to circulate within the transverse ventilation duct 8.

[0082] The energy-saving air conditioning device can regulate the airflow between different breeding layers to achieve ventilation, heat exchange and drying.

[0083] In this embodiment, a ten-layer aquaculture structure 3 is used. The number of layers can also be set according to actual needs, such as 5, 6, 7, etc.

[0084] The structure of the breeding facility 3 can be adopted from the existing three-dimensional insect breeding platform, such as a breeding box, or refer to patents CN115251011A, CN113317283A, CN117016495A and CN220728829U.

[0085] like Figure 3 and 4 As shown, the breeding mechanism 3 in this embodiment includes a mounting frame 3-9, a left insect-blocking plate 3-4, a right insect-blocking plate 3-6, a conveyor belt 3-5, an active roller 3-7, a driven roller 3-1, and a feeding / discharging mechanism. The conveyor belt 3-5 is mounted on the mounting frame 3-9 via the active roller 3-7 and the driven roller 3-1. The left insect-blocking plate 3-4 and the right insect-blocking plate 3-6 are mounted on the mounting frame 3-9, with their bottoms in contact with the conveyor belt 3-5. The feeding / discharging mechanism is located at both ends of the conveyor belt 3-5. The feeding / discharging mechanism includes a baffle 3-2 and an electric push rod 3-8. The height of the baffle 3-2 is higher than the height of the left and right insect-blocking plates. This creates a transverse ventilation duct 8 in the space between the baffle 3-2 and the left and right insect-blocking mesh panels. The transverse ventilation duct 8 may be unstructured and can be configured as a breathable mesh, a sealing plate 12 with ventilation holes 7-8, etc., as needed. In this embodiment, no structure is provided. The driving roller and / or driven roller 3-1 are equipped with a power mechanism; in this embodiment, the driving roller is equipped with the power mechanism.

[0086] The conveyor belt 3-5 is made of breathable plastic mesh, metal mesh or cloth; in this embodiment, plastic mesh is used.

[0087] Since the conveyor belt 3-5 is long, it is prone to bending after material is laid. Therefore, a support mesh plate 3-3 can be installed in the middle of the conveyor belt 3-5, close to the top, to improve the support force of the conveyor belt 3-5. The support mesh plate 3-3 can be installed as a whole, or it can be installed under the conveyor belt 3-5 at the feeding end and / or the discharging end. In this embodiment, the support mesh plate 3-3 is installed at the feeding end, which can effectively prevent the material from squeezing and deforming the conveyor belt 3-5 at the feeding end during feeding.

[0088] The energy-saving three-dimensional insect breeding system also includes several water heating mechanisms 10, which are installed at the bottom of the breeding mechanism 3.

[0089] The water heating mechanism 10 is installed at intervals at the bottom of the breeding mechanism 3, or the water heating mechanism 10 is installed at the bottom of the lowest layer of the breeding mechanism 3.

[0090] This implementation adopts a water heating system 10 installed at the bottom of the breeding facility 3.

[0091] The water heating mechanism 10 is a conventional water heating mechanism 10, which includes water heating pipes, inlet and outlet. The water heating mechanism 10 can be connected to the heating device. The specific structure is not described in detail.

[0092] The natural ventilation device is a device that uses the heat generated during the insect breeding process to create a pressure difference between the air inlet 1-1 and the air outlet, thereby enabling air to circulate within the transverse ventilation duct 8.

[0093] The natural ventilation device includes an air inlet mechanism 1 and / or an air outlet mechanism 2;

[0094] The air intake mechanism 1 includes a main air intake 1-3 that is installed on the side of the three-dimensional multi-layer aquaculture platform and sealed to the side. The air intake mechanism 1 can be configured with different structures according to actual needs. In this embodiment, the main air intake 1-3 is an integral structure that completely covers the side of the three-dimensional multi-layer aquaculture platform. This type of structure is suitable for the overall feeding and discharging aquaculture mode of a single aquaculture platform and can perform ventilation operation on each transverse ventilation duct 8 without discrimination.

[0095] Several air inlet pipes 1-2 are installed on the main air inlet section 1-3 at different locations. The specific positions of the air inlet pipes 1-2 can be set as needed, such as at the top or bottom of the main air inlet section 1-3, to facilitate rapid and uniform air intake. In this embodiment, they are set at the bottom of the main air inlet section 1-3. An air inlet valve is installed on the air inlet pipe 1-2 to control the air volume. Heat exchange mechanisms, filtration mechanisms, sterilization mechanisms, and other equipment can be installed at the inlet of the air inlet pipe 1-2 as needed to perform operations such as filtering, sterilizing, heating, cooling, dehumidifying, and humidifying the air, thereby more effectively regulating the insect breeding and drying environment and improving breeding efficiency.

[0096] In this invention, the air inlet 1-1 consists of several elliptical holes, the length of which is slightly less than the length of the transverse ventilation duct 8. This ensures a large air volume. The air inlet valve is a similar butterfly valve, including a rectangular valve plate 1-5. The rectangular valve plate 1-5 is fixed on the air valve shaft 1-4, and the air valve shaft 1-4 is installed together with the motor.

[0097] For areas where air temperature and humidity do not change much and are suitable for insect farming in the long term, it is not necessary to install an air intake mechanism.

[0098] The air outlet mechanism 2 is located on the other side of the three-dimensional multi-layer aquaculture platform and is sealed to the main air outlet 2-5 on the side. The air outlet mechanism 2 can be configured with different structures according to actual needs. In this embodiment, the main air outlet 2-5 is an integral structure that completely covers the other side of the three-dimensional multi-layer aquaculture platform. This type of structure is suitable for the overall feeding and discharging aquaculture mode of a single aquaculture platform and can perform ventilation operation on each transverse ventilation duct 8 without discrimination.

[0099] The air outlet mechanism 2 and the air inlet mechanism 1 are set on both sides of the longitudinal direction of the breeding platform, so that the air flows laterally on the breeding platform, which can greatly reduce the length of air flow, effectively reduce wind resistance, and improve ventilation efficiency.

[0100] An air outlet pipe 2-3 is installed on the main air outlet section 2-5, and an air outlet valve 2-2 is installed on the air outlet pipe 2-3 to adjust the air volume.

[0101] The air outlet duct 2-3 is located at the top of the three-dimensional multi-layer aquaculture platform, and the position of the air outlet duct 2-3 is higher than the three-dimensional multi-layer aquaculture platform; air circulates in the transverse ventilation duct 8 between two adjacent aquaculture platforms.

[0102] During insect farming, the insects' activity generates heat, causing the air temperature inside the farming platform to be higher than the temperature of the air outlets by 2-3 vents.

[0103] During the insect drying process, the introduction of hot air causes the air temperature inside the breeding platform to be higher than the temperature at the air outlets of ducts 2-3. Therefore, throughout the entire operation of the breeding platform, the air temperature inside the platform remains higher than the air temperature at the air outlets of ducts 2-3, creating a temperature difference between the inlet ducts 1-2 and the outlets. This causes the hot air to rise and be expelled through the outlets 2-3, creating a negative pressure environment inside the breeding platform. This generates suction, automatically drawing air from the inlet ducts 1-2 into the breeding platform, forming a self-circulating air system. This provides natural ventilation to the breeding platform, is low-cost, and pollution-free.

[0104] The higher the exhaust duct 2-3 is, the better the natural ventilation effect. To further improve the ventilation effect, a negative pressure fan 2-1 can be installed on the exhaust duct 2-3. The air discharged from the exhaust outlet can be collected and treated for air purification as needed, depending on the actual situation.

[0105] Depending on the actual breeding environment, insulation layers 5 can be installed on the air inlet mechanism 1 and the air outlet mechanism 2 to effectively ensure heat exchange, reduce energy consumption, and ensure that insects always have a good growth environment.

[0106] like Figure 5 As shown, in order to improve the heat exchange effect, especially in winter when the air temperature is low and heating is required, the technical solution adopted by the present invention is: energy-saving ventilation also includes a waste heat utilization mechanism, and the air inlet pipe 1-2 and the air outlet pipe 2-3 are connected to the waste heat utilization mechanism.

[0107] The structure of the waste heat utilization mechanism can be selected according to the actual situation, and suitable heat exchange equipment can be selected. The mechanism used in this embodiment is as follows: the waste heat utilization mechanism is a waste heat outlet 2-4 set on the top of the three-dimensional multi-layer aquaculture platform. The air inlet pipe 1-2 passes through the waste heat outlet 2-4. A heat insulation layer 5 is provided between the top of the three-dimensional multi-layer aquaculture platform and the waste heat outlet 2-4. The waste heat outlet 2-4 is connected to the outlet.

[0108] Using the above-described mechanism, the air inlet duct 1-2 passes through the waste heat utilization section in the reverse direction. The heat from the air in the waste heat utilization section is used to heat the air inside the air inlet duct 1-2, thereby raising its temperature and providing heating and ventilation for the aquaculture platform. Alternatively, the air inlet duct 1-2 can be passed entirely through the air outlet section as needed to further improve waste heat utilization efficiency.

[0109] The energy-saving air conditioning device includes an air inlet regulating mechanism 7 and an air outlet regulating mechanism 9, which are respectively installed on both sides of the three-dimensional multi-layer aquaculture platform;

[0110] like Figure 6 As shown, the air intake adjustment mechanism 7 includes an upper air intake shaft and an air intake shield cloth disposed on the upper air intake shaft 7-2. The upper air intake shaft 7-2 is fixed to the upper part of the three-dimensional multi-layer aquaculture platform. The air intake shield cloth is provided with an air intake fully sealed area 7-3. Several horizontal air inlets 7-4 are provided at the bottom of the air intake fully sealed area 7-3. The horizontal air inlets 7-4 are connected to the horizontal ventilation duct 8 between two adjacent aquaculture platforms. The length of the air intake fully sealed area 7-3 is not less than the height of the aquaculture platform. In this embodiment, one horizontal air inlet 7-4 is provided. Multiple horizontal air inlets 7-4 can also be provided as needed or at intervals.

[0111] like Figure 6As shown, the air outlet adjustment mechanism 9 includes an upper air outlet rotating shaft 9-1, a lower air outlet rotating shaft 9-6, and an air outlet shielding cloth. The upper air outlet rotating shaft 9-1 and the lower air outlet rotating shaft 9-6 are respectively fixed to the upper and lower parts of the three-dimensional multi-layer aquaculture platform. The two ends of the air outlet shielding cloth are respectively fixed to the upper air outlet rotating shaft 9-1 and the lower air outlet rotating shaft 9-6. The air outlet shielding cloth is provided with a fully sealed air outlet area 9-3, a partially open air outlet area 9-4, and a fully open air outlet area 9-2. The partially open air outlet area is provided with several horizontal air outlets 9-5. The horizontal air outlets 9-5 are connected to the horizontal ventilation duct 8 between two adjacent aquaculture platforms. The lengths of the three areas, namely the fully sealed air outlet area 9-3, the partially open air outlet area, and the fully open air outlet area 9-2, are not less than the height of the aquaculture platform.

[0112] The air inlet and outlet windproof fabrics can be made of durable, non-breathable materials, such as a structure with a layer of plastic on the fabric.

[0113] The upper air inlet shaft 7-2, upper air outlet shaft 9-1, and lower air outlet shaft 9-6 are respectively connected to the first power mechanism 7-1. The first power mechanism 7-1 can be a motor, a chain drive mechanism, etc., and in this embodiment, a motor is used.

[0114] like Figure 7 As shown, the air intake adjustment mechanism 7 also includes a lower air intake shaft 7-7, which is fixed to the lower part of the three-dimensional multi-layer aquaculture platform. The air intake shield is also provided with a fully open air intake area 7-5 and a partially open air intake area 7-6, and the transverse air intake port 7-4 is located in the partially open air intake area 7-6.

[0115] like Figure 8 As shown, during the air-drying process, the air-drying layer is ventilated and dried, while the non-air-drying layer is sealed. This results in the non-air-drying layer not being able to ventilate, which makes it difficult for insects to live and grow. Therefore, in this embodiment, the fully sealed air intake area 7-3, the fully sealed air outlet area 9-3, and the partially open air outlet area 9-4 are provided with ventilation holes 7-8. The ventilation holes 7-8 can create micro-ventilation within the breeding structure 3, which will not affect the normal operation of the breeding process.

[0116] During the ventilation process in aquaculture, there is a problem that the wind speed at the air inlet and outlet is different from that at the fan, which in turn leads to different ventilation volumes. To solve the above technical problem, the ventilation holes 7-8 can be distributed on the windproof cloth in a manner that is smaller at the top and larger at the bottom or sparser at the top and denser at the bottom. This can effectively adjust the ventilation volume in the aquaculture facility 3 and achieve uniform ventilation.

[0117] like Figure 9As shown, if the breeding mechanism 3 is relatively long, it will be difficult to drive the shaft to rotate using a single motor. Therefore, the shaft can be set as multiple shafts according to the structure of the breeding platform, with each shaft connected to a power mechanism.

[0118] In this embodiment, there are two air inlet shafts 7-2, 9-1, and 9-6.

[0119] Example 2

[0120] like Figure 10-12 As shown, an energy-saving method for air-drying insects, using the apparatus of Example 1, includes the following steps:

[0121] (1) Place the insect feed and larvae on the conveyor net, and then seal the breeding platform;

[0122] (2) When the temperature is low, adjust the air inlet and outlet air conditioning mechanism to the fully sealed area, and the water heating mechanism will heat up by 10. The heat will flow from bottom to top, and the temperature inside the entire breeding platform will be quickly raised to the suitable breeding temperature.

[0123] (3) Adjust the air inlet and outlet adjustment mechanism to the fully open area. Adjust the opening degree and time of the air outlet valve 2-2 and the air inlet valve according to the ambient temperature and humidity and the internal temperature and humidity of the breeding platform. The air is automatically drawn into the breeding platform under the action of the pressure difference between the inlet and outlet. The air flows in the transverse ventilation duct of each layer of the breeding mechanism to keep the breeding platform with suitable temperature and humidity.

[0124] (4) When the breeding is finished or when air drying is required, adjust the air intake channel of the main air intake section 1-3 of the air intake mechanism 1 to the layer where the water heating mechanism 10 is installed, and adjust the air outlet 9-4 of the air outlet mechanism 2 to the upper part of the air drying layer. After being heated by the water heating pipe, the hot air penetrates from bottom to top and enters the air outlet pipe from the horizontal ventilation duct at the top of the breeding platform to air dry the materials on the breeding mechanism. If the air drying speed is slow, the negative pressure fan 2-1 can be turned on to improve the air drying efficiency.

[0125] (5) When the drying layer reaches the drying requirements, discharge the material, and then adjust the open area 9-4 of the air outlet of the air outlet mechanism 2 to the layer above the material outlet layer for drying. By doing this, the drying and discharge operation of all the breeding mechanisms 3 in the breeding platform can be completed, thus completing the breeding drying operation.

[0126] During the air-drying process, continuous negative pressure ventilation can be used, or intermittent negative pressure ventilation can be used for a period of time, followed by a pause before resuming ventilation. For example, ventilate under negative pressure for 20 minutes, stop for 40 minutes, and then ventilate for another 20 minutes. The ventilation intervals can be uniform or non-uniform, depending on the settings. For example, ventilate for 30 minutes, stop for 3 minutes, then ventilate for 20 minutes, stop for 40 minutes, and so on. Intermittent ventilation allows for more thorough mixing of hot air and materials, improving energy utilization and reducing energy consumption.

[0127] Experimental Example 1

[0128] Using the above-mentioned structure, the breeding layer consists of three layers, with a length of 8m, a width of 4m, a fabric thickness of 15cm, and a transverse ventilation duct of 85cm. Black soldier fly larvae are bred by feeding fourth-instar larvae, which are then bred for seven days and air-dried until the moisture content of the material is around 45%. The air-drying process uses continuous negative pressure ventilation. Energy consumption is then assessed.

[0129] Comparative Example

[0130] The structure is basically the same as that of Experimental Example 1, except that each layer of breeding structure 3 is sealed, and an air inlet pipe 1-2 is connected to one side of each layer of breeding structure 3, and an air outlet pipe 2-3 is connected to the other side. The air inlet pipe 1-2 is connected to the hot air mechanism.

[0131] The specific data is shown in Table 1 below:

[0132] Table 1 Energy consumption test results for different ventilation methods

[0133]

[0134] As shown in the table above, the ventilation and air conditioning method of the present invention can effectively reduce energy consumption when raising black soldier fly larvae. The energy-saving effect is best in spring, autumn and summer when the air is dry and the temperature is high, reaching 158.8%-254.2%. The energy-saving effect is also relatively good in winter when the air temperature is low, reaching 41.1%.

[0135] Example 3

[0136] It is basically the same as Example 1, except that:

[0137] like Figure 13 and 14 As shown, the structures of the air inlet 1-3 and the air outlet can be configured in different forms according to the actual situation. For example, the main air inlet 1-3 includes several small air inlets 1-8, which completely cover the sides of the three-dimensional multi-layer aquaculture platform. Each small air inlet 1-8 can be equipped with an air inlet pipe 1-2 and an air inlet valve, which can more accurately control the air volume. Alternatively, one air inlet pipe 1-2 and an air inlet valve can be used.

[0138] The main air outlet includes several smaller air outlets 2-8, which completely cover the other side of the three-dimensional multi-layer aquaculture platform. Each smaller air outlet 2-8 can be equipped with an air outlet duct 2-3 and a negative pressure fan 2-1, allowing for more precise control of the airflow; alternatively, a single air outlet duct 2-3 and a negative pressure fan 2-1 can be used.

[0139] The small air inlets or small air outlets 2-8 are staggered on both sides of the three-dimensional multi-layer aquaculture platform. The small air inlets 1-8 and small air outlets 2-8 can be arranged horizontally or vertically; this embodiment uses a vertical arrangement.

[0140] In this embodiment, four small air inlets 1-8 and four small air outlets 2-8 are used. Two adjacent small air inlets 1-8 share one air inlet valve and are divided into natural air inlets and dry hot air inlets. Two adjacent small air outlets 2-8 share one air outlet valve 2-2 and are divided into natural air outlets and dry hot air outlets.

[0141] The air inlet and outlet using the above structure are as follows: Figure 15 As shown:

[0142] The above structure allows for simultaneous ventilation and drying of the aquaculture platform, which helps improve the platform's efficiency and enables tiered aquaculture.

[0143] Example 4

[0144] like Figure 16 and 17 As shown, it is basically the same as in Embodiment 1, except that the main air intake can also be configured as follows as needed: the main air intake includes an air intake box 1-7, and the air intake box 1-7 is connected to the transverse ventilation duct 8 of each floor through the air intake duct 1-6.

[0145] The main air outlet includes an air outlet box 2-6, which is connected to the horizontal ventilation duct 8 of each floor through an air outlet duct 2-7.

[0146] The above structure allows for more precise air intake and exhaust, improving ventilation efficiency.

[0147] Example 5

[0148] like Figure 18 As shown, it is basically the same as Embodiment 1, except that the following technical solution is adopted: air regulating plates 7-9 are installed on one or both sides of the three-dimensional multi-layer aquaculture platform, and the air regulating plates 7-9 are located inside the air inlet regulating mechanism 7 or the air outlet regulating mechanism 9. This embodiment uses air regulating plates 7-9 installed on the air inlet side.

[0149] The air regulating plates 7-9 are several plates that are wider at the top and narrower at the bottom; in this embodiment, there are four plates. Setting up the aforementioned air regulating plates 7-9 can effectively control the air intake and exhaust volume of each layer of the breeding structure 3, making the air intake and exhaust vents smaller where the air pressure loss is small, and larger where the air pressure loss is large. This can effectively adjust the air intake volume of each layer, making the air intake volume of each layer uniform.

[0150] In addition to the structure described above, the air regulating plate 7-9 can also be made of several plates with through holes 15, which are either smaller at the top and larger at the bottom or sparser at the top and denser at the bottom.

[0151] The above-mentioned mechanism can also effectively achieve uniform ventilation within the aquaculture layer through the action of the air regulating plate 7-9.

[0152] Example 6

[0153] like Figure 19 and 20 As shown, basically the same as in Embodiment 1, the breeding facility 3 of the present invention has a sealing plate 12 and a ventilation regulating plate 14 on the transverse ventilation duct 8, which are equipped with the energy-saving air regulating device. The sealing plate 12 is provided with air holes 13, and the ventilation regulating plate 14 is provided with through holes 15. The ventilation regulating plate 14 is installed together with the second power mechanism 16. The second power mechanism 16 drives the ventilation regulating plate 14 to move, thereby opening and closing the air holes 13.

[0154] The second power mechanism 16 can be a power mechanism capable of linear motion; in this embodiment, an electric push rod 3-8 is used.

[0155] Example 7

[0156] like Figure 21 As shown, it is basically the same as in Embodiment 1. The energy-saving air conditioning device includes a sealed hose 19 installed in the transverse ventilation duct 8. The sealed hose 19 is installed together with the air pump 22 through the air pipe 20. The air pipe 20 is provided with an inflation pneumatic valve 17. The sealed hose 19 is installed together with the vacuum pump 23 through the vacuum pipe 21. The vacuum pipe 21 is provided with an exhaust pneumatic valve 18.

[0157] Using the above structure, the opening and closing of the transverse ventilation duct 8 is achieved through inflation and deflation, thereby regulating the airflow into and out of the aquaculture platform. The structure is simple, easy to operate, and provides good sealing. In this embodiment, a single vacuum pump 23 and air pump 22 are used for inflation and deflation control; however, several vacuum pumps 23 and air pumps 22 can also be used for inflation and deflation control.

[0158] Example 8

[0159] like Figure 22 and 23As shown, basically the same as in Embodiment 1, the energy-saving air conditioning device includes a wind shield 26. One end of the wind shield 26 is fixed to the upper part of the transverse ventilation duct 8 through a wind shielding pivot. The other end of the wind shield 26 is installed together with the third power mechanism 24. The third power mechanism 24 drives the wind shield 26 to rotate to realize the opening and closing of the transverse ventilation duct 8.

[0160] The third power mechanism 24 uses an electric motor, which drives the wind shield 26 to rotate via a rotating shaft, thereby opening and closing the transverse ventilation duct 8.

[0161] This embodiment has a simple structure, is easy to operate, and is practical for small-scale aquaculture platforms.

[0162] Example 9

[0163] like Figure 24 and 25 As shown, it is basically the same as Embodiment 1, except that the waste heat utilization mechanism in this invention further includes an air intake waste heat utilization section 1-9, which is connected to the main air intake section and connected to the waste heat outlet section through a heat exchange mechanism. The heat exchange mechanism is generally a heat-conducting plate or heat dissipation plate made of a material with high thermal conductivity. In this embodiment, heat exchange plates 1-10 are used.

[0164] In Example 1, the waste heat utilization mechanism uses an air inlet pipe passing through the waste heat utilization section to heat the air inside the pipe, thus achieving waste heat utilization. However, the contact area between the air inlet pipe and the waste heat utilization section is relatively small, resulting in a mediocre waste heat utilization effect. This embodiment uses an air inlet waste heat utilization section, which is a box-like structure, roughly the same size as the aquaculture platform. This effectively increases the contact area with the waste heat outlet section, significantly improving waste heat utilization efficiency. The air inlet waste heat utilization section can use the method of this invention, contacting the waste heat outlet section via a heat exchange plate, or other methods, such as enclosing the air inlet waste heat utilization section within the waste heat outlet section, etc., as long as it increases the area and improves waste heat utilization efficiency.

[0165] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
