[0027] In the following, only some exemplary embodiments are described briefly. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and the description are considered to be exemplary in nature and not limiting.

[0028] As Figure 1 and Figure 2 shown, a quick ventilation device for breeding according to the present application comprises an air duct pipe 1, a waterproof breathable membrane 2, a guide plate 3, a dehumidification filter 4 and a drain pipe 5. The main purpose of the design of this system is to effectively solve the problem of condensation and water accumulation inside the ventilation duct in the traditional ventilation system in different seasons and changing environments, and the resulting structural rust and corrosion.

[0029] The air duct pipe 1 is the main component of the device, which is internally structured with a path specially designed to guide outdoor air to the desired indoor space. This air duct design takes into full consideration the actual needs of different scale breeding farms. In order to prevent the intrusion of external rainwater and the excessive humidity inside the duct caused by condensate water due to the temperature difference between the inside and outside, a waterproof breathable membrane 2 is specially provided at the air inlet. The waterproof breathable membrane 2 has strong hydrophobicity and air permeability, which prevents liquid raindrops while ensuring that enough fresh air can smoothly pass through the membrane layer into the duct.

[0030] The guide plate 3 is placed at a specific position inside the air duct pipe 1 and can be adjusted in angle according to the needs at different times, so as to optimize the flow direction and speed of the incoming air according to the climate changes brought by the four seasons or the obvious differences in indoor and outdoor temperatures between day and night, further reducing the increase in humidity inside the duct and avoiding the risk of oxidation of the metal duct due to moisture.

[0031] In order to further solve the potential threat of excess moisture in the air to the overall structure, a dehumidification filter 4 component with water absorption function is installed before the air outlet, which can effectively filter out gas carrying moisture and reduce the probability of these gaseous small particulate matters turning into liquid and dripping on the equipment.

[0032] In addition, the lowest end of the entire rapid ventilation system is provided with a drain pipe 5 specially used for guiding away the accumulated condensed liquid. The water droplets intercepted from the waterproof and breathable membrane 2 and the liquid separated during the filter screen processing will be collected at the bottom and then discharged outside the system through this path. This series of components are assembled in a certain order and tightly connected to form a complete anti-condensation drainage system.

[0033] In one embodiment, plastic or other materials not susceptible to corrosion can be used as the material of the air duct pipe 1. The waterproof and breathable membrane 2 as the core element is made of high polymer composite material. The adjustable guide vane part is made of stainless steel material and is installed in its designated air duct section through axial support points and fixed seats to meet the angle adjustment requirements. As for the key part of the filter effect, the dehumidifying filter screen 4 is made of hydrophilic fiber and cooperates with the honeycomb grid skeleton to provide a larger specific surface area, thereby enhancing the absorption capacity. Finally, all areas where liquid droplets are produced are connected to the external drainage ditch, and the form of the drain pipe 5 may be a curved PVC pipeline.

[0034] This special combination solves the problems existing in the use environment of the rapid ventilation device. For example, in the spring and autumn seasons with large diurnal temperature difference, the guide plate 3 can change the inclination degree according to the specific situation to make the incoming air move along the set route efficiently, so that the side wall with lower temperature is difficult to contact the high-temperature and humid external air. During the summer with high temperature and high humidity, the filter screen operates powerfully to quickly reduce the water content concentration in the air to be discharged, ensuring that there is no opportunity to form liquid water molecules. Even if there is slight condensation on some surfaces in winter, the pre-arranged drainage mechanism can timely remove the trace amount of water outside the body, greatly reducing the possibility of corrosion of iron parts due to long-term exposure of the pipeline to humid conditions. Such carefully arranged measures fundamentally eliminate the probability of such accidents and maintain a safe and reliable environment quality in good operating condition.

[0035] In one embodiment, the waterproof and breathable membrane 2 of the rapid ventilation device for aquaculture of the present application is made of multiple layers of composite material. The outer layer is a hydrophobic filter layer, which is located at the air inlet and covers the outside of the air duct pipe 1, effectively preventing rainwater from entering the inside of the pipe and ensuring that the air entering the air duct pipe 1 is not affected by external moisture. The inner layer is a hydrophilic filter layer, which is installed inside the outer layer and close to the air duct pipe 1, has good adsorption capacity, and can absorb the trace amount of moisture that penetrates through the outer layer, reducing the risk of condensation.

[0036] The waterproof and breathable membrane 2 has a unique structure in the arrangement of its multiple layers. Specifically, the outer layer is made of specially treated polytetrafluoroethylene or similar hydrophobic fabric, forming a strong and effective protective barrier; while the inner layer can use materials such as cotton or other natural fiber blended with synthetic fiber, which is chosen because such materials have high adsorption capacity for trace water vapor without affecting gas flow. In addition, the inner and outer layers are tightly bonded or directly overlaid, but ensure that the overall air permeability and protection performance are not affected. The entire composite structure is fixed to the opening edge of the air duct pipe 1, forming a firm connection.

[0037] For example, the waterproof and breathable membrane 2 is embedded in a specially designed metal or plastic frame through mechanical processing, and then the frame is nested and installed at the front end of the air duct pipe 1, thereby achieving reliable installation and fixation. In order to ensure the best use effect, precise cutting of each layer of material is required during the manufacturing process, and assembly is completed through high-temperature pressing, ultrasonic welding, or special adhesives to ensure good sealing and long-term stability between components. Such design makes the waterproof and breathable membrane 2 not only prevent external liquid penetration, but also allow necessary gas exchange, thereby protecting the entire system from moisture damage.

[0038] In one embodiment, referring specifically to Figure 2 The waterproof and breathable membrane 2 of the quick ventilation device for aquaculture of the present application is fastened at the air inlet of the air duct pipe 1 by the fixing ring 6. The fixing ring 6 is made of elastic material and can be adjusted according to the different diameters of the actual air inlet, ensuring that the waterproof and breathable membrane 2 is tightly and firmly fixed in the installation position. This design not only improves the structural stability, but also makes the installation more convenient and universal.

[0039] In order to adapt to the diameter changes of different air inlets, the elastic fixing ring 6 has a certain elastic deformation ability. When installing, a moderate pressure can be applied to expand the fixing ring 6 to the appropriate size and fit the inner wall or outer edge of the air duct pipe 1, and rely on its own elastic force to tightly fix the waterproof and breathable membrane 2. Specifically, during installation, the operator only needs to place the waterproof and breathable membrane 2 in the designated installation position and put it into the fixing ring 6; due to the self-adjusting characteristics of the fixing ring 6, it will tightly adhere between the air duct pipe 1 and the waterproof and breathable membrane 2, thereby ensuring the sealing and firmness of the fixation, without the need for additional tools or special equipment, achieving an efficient installation process. This design simplifies the assembly process and achieves good fixing effect in different specifications of air duct pipes 1. For example, in the actual environment of different farms, even if the air duct pipes 1 of different sizes are faced, the elastic fixing ring 6 can still play the expected function, effectively ensuring the stability and efficiency of the ventilation device during operation.

[0040] On this basis, the unique design of the elastic fixing ring 6 provides higher flexibility and compatibility for the entire system, ensuring that even if the air inlet is of different sizes, the reliable fixing state and waterproof performance can be maintained, and the later maintenance and replacement of parts are facilitated. In short, the above features constitute an important part of the quick ventilation device for aquaculture, and have important significance for the functional improvement of the overall structure.

[0041] In one embodiment, further referring to Figure 3 , a waterproof and breathable cover 7 is additionally provided outside the waterproof and breathable membrane 2 of the quick ventilation device for aquaculture. The waterproof and breathable cover 7 is located between the waterproof and breathable membrane 2 and the external environment, effectively preventing large particles and dust from entering the air duct pipe 1, protecting the cleanliness of the internal components, and helping to prolong the service life of the device. The specific structure of the waterproof and breathable cover 7 is composed of multiple layers of composite materials, which can provide good protection and breathability.

[0042] Specifically, the design of the waterproof and breathable cover 7 aims to further enhance the dustproof and waterproof capability of the device without affecting air circulation. The waterproof and breathable cover 7 is covered outside the waterproof and breathable membrane 2 and is tightly connected with the air duct pipe 1 through mechanical fixation or adhesion, forming an additional barrier. This barrier can effectively block impurities during air flow in and out while ensuring sufficient gas permeability. The material of the waterproof and breathable cover 7 is preferably a fabric or film with high strength and durability, which has excellent air permeability and weather resistance.

[0043] In terms of technical implementation, for example, a detachable installation form can be adopted, with buckles or magic tapes being provided around the edges of the waterproof and breathable cover 7, so as to regularly clean or replace the cover. This way not only simplifies the maintenance operation, but also ensures stable operation of the device for a long time, improving the use experience and management efficiency of the aquaculture farmers.

[0044] In one embodiment, referring back to Figure 2 , the guide vane 3 of the quick ventilation device for aquaculture is installed inside the air duct pipe 1, and its structure is unique to achieve flexible air flow control. The guide vane 3 is designed with adjustable angle and consists of multiple fan-shaped blades. Each blade is connected by a pivot 8, so that the entire guide vane 3 can change the inclination angle according to the needs, whether it is manually adjusted or electrically driven. This structure not only adapts to various environmental requirements, but also improves the air management capability. By adjusting the inclination angle of the blades to optimize the direction and flow of the air flow, it effectively prevents the condensation of wet and cold air into water droplets in the pipeline to form dew, and one of the key points of the application of this structure is to precisely control the humidity in the aquaculture environment.

[0045] Specifically, the angle adjustment of the blades can be achieved by setting a driving mechanism in combination with a control system. For example, in one embodiment, an electric motor is installed as a driving source on one side of the outside of the air duct pipe 1, and a power transmission rod passes through the wall and is coupled to the pivot 8 to drive each blade. At the same time, temperature and wind speed sensors are configured to detect changes in internal and external conditions and feed back information to the processor for calculation and processing to obtain the corresponding optimal operating parameters, and then issue execution instructions to control the motor to achieve the purpose of real-time response adjustment. This system can ensure stable operation even under complex and variable natural conditions.

[0046] In one embodiment, the guide vane 3 of the rapid ventilation device for aquaculture of the present application further comprises a sensor 9 installed near the guide vane 3. The sensor 9 is used to monitor the temperature and humidity in the pipe in real time, and is connected to a controller 10. The controller 10 can automatically adjust the angle of the guide vane 3 according to the information fed back by the sensor 9, thereby achieving intelligent adjustment. The controller 10 has multiple control modes preset, including a timing mode, a temperature trigger mode, and a manual adjustment mode, which can be selected by the user according to actual needs.

[0047] Specifically, this intelligent control mechanism further improves the efficiency of the ventilation system and helps to reduce energy consumption. In this structure, the sensor 9 is placed near the guide vane 3 to ensure that the environmental data in the pipe can be accurately obtained and then sent to the controller 10 connected to it. The controller 10 integrates algorithms to process the collected data and accordingly issues instructions to the guide vane 3 installed inside the air duct pipe 1 and adjustable in angle, so that the guide vane 3 can automatically optimize the ventilation effect under different working conditions.

[0048] For example, when the controller 10 receives real-time temperature and humidity information provided by the sensor 9, it will decide the optimal inclination angle of the guide vane 3 based on the built-in logic, and then adjust the guide vane 3 to the set position through an electronic or electromechanical driving system. This ensures that no matter how the external conditions change, timely response can be maintained to maintain a constant and suitable ventilation state. The timing mode changes the position of the guide vane 3 according to a pre-set schedule, while the temperature trigger mode activates the adjustment action when a certain threshold is reached; the manual mode allows the user to manually operate the angle of the guide vane 3 when special needs arise. These mechanisms complement each other to ensure efficient and flexible air circulation control.

[0049] In one embodiment, the dehumidification filter screen 4 of the rapid ventilation device for aquaculture of the present application is made of hydrophilic fiber material, i.e. the dehumidification filter screen 4 is a hydrophilic fiber screen, which has good moisture absorption performance. The dehumidification filter screen 4 is installed before the air outlet of the air duct pipe 1, at the end of the air flow direction, effectively filtering and absorbing the moisture contained in the air introduced through the air duct pipe 1. As the moisture is adsorbed, the hydrophilic fiber will gradually become wet, and after reaching a certain humidity, the collected moisture will be discharged outside the air duct pipe 1 through the drain pipe 5 arranged at the bottom, ensuring the dryness inside the ventilation system. In this way, the problem of condensate accumulation in the pipeline is avoided, and the risk of dewing is significantly reduced.

[0050] For example, a fiber material such as nylon or polyester that has been specially treated to enhance its hydrophilic properties can be selected to make the filter screen that functions as a dehumidification component. The dehumidification filter screen 4 is fixed to the designated position of the air duct pipe 1 by mechanical fasteners or adhesion, and is connected to the drain pipe 5 below, ensuring that any condensate generated due to temperature changes can flow smoothly from the dehumidification filter screen 4 to the drain pipe 5 and then be discharged from the entire system. This structured design can maintain a relatively low humidity environment in the pipeline and ensure long-term efficient operation.

[0051] In one embodiment, the dehumidification filter screen 4 of the rapid ventilation device for aquaculture of the present application is located in front of the air outlet of the air duct pipe 1. To improve the dehumidification effect, the dehumidification filter screen 4 adopts a special multi-layer structure design. Each layer of the filter screen is filled with multiple layers of microporous material, and different layers of microporous material have different pore sizes. Specifically, the microporous material with larger pore size can preliminarily remove large-size moisture particles in the air, and then the microporous material with smaller pore size can further filter and absorb the remaining small-size moisture particles. This step-by-step decreasing pore size design allows the entire dehumidification process to filter and capture moisture particles of various sizes in layers, thereby significantly enhancing the overall dehumidification efficiency during the air flow process.

[0052] For example, these dehumidification filter screens 4 can be installed in the air duct pipe 1 by a buckle method near the air outlet, and are firmly installed by a fixed support. Each layer of microporous material is connected together in an alternating stacking manner, ensuring smooth air flow while maintaining a compact structure, ultimately forming a complete and efficient dehumidification assembly and being connected to the drain pipe in a smooth manner. In addition, there are slight gaps between the microporous structures, allowing part of the air to flow without causing reverse water penetration, thereby achieving stable and continuous efficient operation.

[0053] In one embodiment, the dehumidification filter 4 of the rapid ventilation device for aquaculture of the present application is provided with an additional layer of antibacterial material 11. This layer of antibacterial material 11 is installed inside the dehumidification filter 4 and meets the outside air before it enters the aquaculture space through the air duct 1. By adding this layer of antibacterial material 11, it is ensured that the air circulating from the air duct 1 is not only dried but also receives additional antibacterial and mold protection. This design effectively prevents the breeding of bacteria and mold inside the duct, keeping the entire air circulation path clean and hygienic, thereby ensuring that the air quality in the aquaculture environment is at a high level.

[0054] In actual design, the antibacterial material layer 11 can be made of new materials with good sterilization effect and stability, such as silver ion carrier and zinc complex compound. This material usually has long-term and high-efficiency antibacterial effect and does not significantly decline over time, and has good killing or growth inhibition ability for most harmful microorganisms. The antibacterial material layer 11 can be installed on the dehumidification filter 4 by tight fitting or other connection forms, such as using heat-composite bonding or mechanical inlaying fixation technology to realize its firm assembly. This way ensures that it can continue to function even when exposed to air for a long time under any weather conditions, without the need for frequent component replacement or additional maintenance. In this way, when air flows through the dehumidification filter 4 with this antibacterial material layer 11, the water molecules carried therein will be removed and the potential pathogens attached will also be reduced, making the air flow into the aquaculture space cleaner and healthier.

[0055] In one embodiment, the drain pipe 5 of the rapid ventilation device for aquaculture of the present application has a diameter greater than the pore size of the dehumidification filter 4, to ensure that the condensed water discharged does not accumulate inside the duct and affect air circulation. In addition, the outlet position of the drain pipe 5 is set above a certain height, preventing external contaminants from flowing back into the air duct 1, thereby ensuring the internal air quality and sanitary conditions. Through reasonable diameter difference and installation position selection, this design also facilitates the rapid discharge of condensed water, effectively reducing the possibility of accumulation.

[0056] Specifically, the drain pipe 5 is installed at the bottom of the air duct 1 and is connected to the dehumidification filter 4 to receive the condensed water collected from the dehumidification filter 4. The diameter of the drain pipe 5 is larger than the pore size of the dehumidification filter 4, so that the condensed water can smoothly enter the drain pipe 5 without being hindered by the filter medium. To prevent contamination from flowing in, the outlet of the drain pipe 5 is located at an appropriate height, which is a certain distance above the ground, ensuring that external impurities are not easily backflowed into the ventilation device along with rainwater, etc.

[0057] For example, the drain pipe 5 can be designed to be installed vertically or slightly inclined at the bottom of the air duct pipe 1, and extend to the outside of the ventilation device for a sufficient length and then raise the end outlet. Such a structure not only facilitates the hydraulic flow of water to flow out smoothly, but also forms a natural barrier due to the physical height difference, preventing the backward invasion of pollutants from low water sources into the pipeline. At the same time, the design of a larger diameter allows the condensed water to be quickly drained, and will not be stored in the system due to slow flow rate.

[0058] In one embodiment, the air duct pipe 1 of the rapid ventilation device for aquaculture of the present application is coated with a corrosion-resistant coating 12. The coating is selected from materials with good adhesion and weather resistance, which can effectively resist moisture erosion and prevent metal materials from rusting and corroding during long-term use. This coating treatment is particularly suitable for aquaculture sites that need to operate continuously and are susceptible to humid environments. In addition, the corrosion-resistant coating 12 not only protects the metal structure of the air duct pipe 1 from erosion, but also indirectly ensures the efficient operation of the entire ventilation system.

[0059] In a typical installation environment, the air duct pipe 1 is located on the path from outdoor air into the aquaculture space, and is in a complex use environment, especially in areas with high humidity or frequent climate changes, its corrosion resistance is particularly important. Specifically, by uniformly spraying a specially formulated corrosion-resistant coating on the interior surface of the air duct pipe 1, the coating is tightly attached to the substrate, and a specific curing process is used to firmly fix it, avoiding wear and tear during daily operations. To ensure the integrity and effectiveness of the coating, it can also be strictly tested and tested before installation.

[0060] Specifically, a composite material based on epoxy resin can be used as the main component of the coating, which not only has excellent mechanical properties and chemical resistance, but also maintains stable physical properties under various harsh conditions. For example, in practical applications, the clean and dry air duct pipe 1 is first placed in a special spraying room, and the inside of the pipe is sprayed according to the preset parameters, and then the coating is cured by high temperature baking and other processes to achieve the best adhesion effect. This process ensures that the coating can effectively resist moisture for a long time and maintain the good working condition of the air duct pipe 1 inside.

[0061] In actual operation, when the device is in use, outdoor air first enters the air flow path inside the duct pipe 1, and needs to pass through the waterproof air permeable membrane 2 for preliminary filtration before entering. The waterproof air permeable membrane 2 blocks rainwater while allowing air to pass through, thereby avoiding the occurrence of condensation inside the duct pipe 1. The air passes through the flow guide plate 3. At this time, the flow guide plate 3 can be adjusted in angle according to different seasons and changes in ambient temperature, so as to optimize the flow direction and speed of the air and reduce the humidity inside the pipe. Subsequently, the air must pass through the dehumidification filter screen 4 before reaching the air outlet. The dehumidification filter screen 4 absorbs moisture in the air to prevent water droplets from condensing inside the pipe, further reducing the condensation probability. The condensed water collected by the waterproof air permeable membrane 2 and the water produced at the dehumidification filter screen 4 are all collected into the drain pipe 5 and discharged by it, so as to ensure that the duct pipe 1 as a whole remains in a dry state. The entire process constitutes a complete anti-condensation drainage system, which guarantees that the ventilation device can effectively prevent condensation and rust corrosion inside the duct pipe 1 at any time of operation.

[0062] The exemplary systems and methods of the present application have been specifically shown and described herein in connection with the exemplary embodiments, but it will be apparent that many modifications and variations can be affected therein by those skilled in the art without departing from the spirit and scope of the application, as defined in the appended claims.
