Description

Technical Field

[0001] This utility model relates to aquaculture, and in particular to a ventilation and air exchange device for aquaculture greenhouses driven by concentrated photovoltaic power generation. Background Technology

[0002] Aquaculture greenhouses are a method of raising aquatic plants and animals using large greenhouse structures. Their main features are that they are not affected by seasons or climate, and can isolate pests and diseases, providing a stable breeding environment for aquatic plants and animals.

[0003] While greenhouses provide insulation, poor air circulation often leads to high humidity and CO2 concentrations, which can negatively impact crop growth, especially during the high temperatures of summer. Ventilation devices are needed to ensure adequate air circulation, and the timing and intensity of ventilation should be adjusted according to the actual situation. However, this process is costly and energy-intensive.

[0004] Although some greenhouses have adopted photovoltaic ventilation systems, the long, cold winters require heating the air for ventilation, resulting in high energy consumption. Furthermore, the short daylight hours in winter mean that traditional photovoltaic power generation devices are less than one-third the efficiency of thermal power plants, making it difficult to meet energy needs and necessitating backup power supplies. In summer, the long daylight hours and high temperatures mean that despite the extended sunshine, ventilation equipment still consumes a lot of energy, and traditional photovoltaic power generation devices still face the problem of operating under overload. Compared to traditional photovoltaics, concentrated photovoltaics (CPV) has higher power generation efficiency, but its construction costs are high. Especially since it is also installed outdoors like traditional photovoltaic devices, it needs to be protected against wind, frost, rain, snow, fog, hail, and other weather conditions, making it more susceptible to weather influences and increasing maintenance costs. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a new energy gust-type ventilation device for aquaculture greenhouses that is environmentally friendly, emission-reducing, has high photoelectric conversion efficiency, and high ventilation efficiency.

[0006] This utility model relates to a new energy-efficient gust-type ventilation device for aquaculture greenhouses, comprising: a drive circuit, a battery, a cooling pump, a generator, an aeration pump, an electric heater, a reversing valve, a threaded telescopic rod, an aquaculture greenhouse, an exhaust fan, a decomposition tank, an aquaculture pond, a porthole, an air-lift filter, an exhaust valve, and related connecting pipes: a generator inlet pipe, an aeration inlet pipe, an upper air pipe, an aeration pipe, a main air pipe, a lower air pipe, a T-shaped pipe, and a generator outlet pipe. The generator is connected to the battery via wires, and the battery is connected to the drive circuit via wires. The small end of the cooling pump is connected to the generator's cooling pipe inlet via the generator inlet pipe, and the generator's cooling pipe outlet is connected to the T-shaped pipe via the generator outlet pipe. The pipe consists of a T-shaped pipe, one end of which is connected to an exhaust valve, and the other end to the lower left port of a reversing valve. The upper left port of the reversing valve is connected to the outlet of the electric heater via an aeration inlet pipe. The outlet of the electric heater is connected to the small end of the aeration pump. The upper right port of the reversing valve is connected to the main air pipe via an upper air pipe, and the lower right port of the reversing valve is connected to the main air pipe via a lower air pipe. The decomposition tank and the breeding tank are located inside the breeding shed, each with an air-lift filter at the bottom. The air-lift filter is connected to the main air pipe via an aeration pipe. The breeding shed has windows on both sides, with exhaust fans located inside the windows and portholes located outside the windows. The upper end of the portholes is connected to the upper end of the windows via a movable hinge, and the movable hinge on the outside of the portholes is connected to the movable hinge on the upper side of the breeding shed via a threaded telescopic rod.

[0007] The drive circuit includes: a heat dissipation switch, a heat dissipation pump motor, an aeration pump motor, an electric heater resistance wire, a washing machine forward / reverse control, an exhaust fan motor, an exhaust fan switch, an electric heater switch, and a ventilation switch. The heat dissipation pump motor is directly connected to the battery via the heat dissipation switch; the electric heater switch is connected in series with the electric heater resistance wire; the aeration pump motor is connected in parallel with the electric heater resistance wire via the electric heater switch, and then connected in series with the battery via the ventilation switch; two exhaust fan motors are connected in parallel to the washing machine forward / reverse control, and the washing machine forward / reverse control is connected to the battery via the ventilation switch.

[0008] The cooling pump includes: a filter screen, a grid plate, an axial flow fan, and a housing. The filter screen is located on the left side inside the large end of the housing, and the grid plate is located on the right side of the filter screen, providing support and limiting the filter screen. The axial flow fan is located on the right side inside the large end of the housing and on the left side of the small end.

[0009] The shell has a cylindrical structure at the large end and a conical structure at the small end, forming a flow collector.

[0010] The aeration pump and the cooling pump are of the same model and specification.

[0011] The generator is a trolley-type concentrating photovoltaic generator, comprising: a heat dissipation pipe, a trough-shaped photovoltaic panel, a trough-shaped reflector, a support column, directional wheels, a base plate, a handwheel, a support plate, a strut, a steering wheel, and a spindle. Two sets of directional wheels are located on either side of one end of the base plate, and two sets of steering wheels are located on either side of the other end of the base plate. The bottom of the support plate is fixedly connected to the base plate. The upper shaft hole of the support plate is movably connected to the support column via the spindle. The outer end of the spindle is fixedly connected to the handwheel, and the middle section of the spindle is fixedly connected to the support column. The upper end of the support column is fixedly connected to the backlighting surface of the trough-shaped reflector. The trough-shaped reflector is connected to and supports the heat dissipation pipe via the strut. The centerline of the heat dissipation pipe is located at the focal point of the trough-shaped reflector. The backlighting surface of the trough-shaped photovoltaic panel is fixedly connected to the lower side of the heat dissipation pipe, and the light-receiving surface faces the reflective surface of the trough-shaped reflector.

[0012] The heat dissipation pipe is a transparent glass tube.

[0013] The upper end of the support plate is provided with a shaft hole, and it is a symmetrical piece.

[0014] The support rod consists of four pieces, located on the front and rear sides of the heat dissipation pipe and the grooved reflector, and symmetrically arranged at both ends.

[0015] The breeding shed is an arched, transparent shed.

[0016] The exhaust fan is a bidirectional exhaust fan, which is connected to the washing machine's forward and reverse control controller via a wire.

[0017] The porthole has a louvered check valve structure and a movable hinge on the outside.

[0018] The working principle of this invention is as follows: Based on the angle of direct sunlight during different solar terms, the angle of the arc-shaped reflector is adjusted by rotating the handwheel to face the direct sunlight, concentrating the light and allowing the arc-shaped photovoltaic panel to acquire more energy. The arc-shaped reflector and the arc-shaped photovoltaic panel have high angle compatibility, low requirements for the angle of direct sunlight, and require fewer adjustments, thus providing a more uniform power supply to the battery. The generator is a trolley-type concentrating photovoltaic generator, which can be flexibly turned to face the direct sunlight. The arc-shaped reflector and the arc-shaped photovoltaic panel have high angle compatibility, low requirements for the angle of direct sunlight, and require fewer adjustments, thus providing a more uniform power supply to the battery.

[0019] The battery acts as a constant voltage source for the drive circuit, ensuring the motor operates smoothly. Depending on the impact of day and night length on power generation in winter and summer, and the different requirements for water filtration, aeration, and ventilation due to varying water and air temperatures in winter and summer, different branches are connected via different switches to perform filtration, aeration, and ventilation.

[0020] In winter, low water and air temperatures result in low evaporation and reduced oxygen consumption in the aquaculture and decomposition ponds. Therefore, the portholes can be closed to prevent cold air from entering the greenhouse and reduce heat loss. During the day, the cooling switch is closed, activating the cooling pump motor and starting the pump. The reversing valve is positioned upwards, allowing cold air from outside the greenhouse to pass through a filter screen and then into the generator's cooling pipes via the generator's inlet pipe, providing ventilation and cooling. After passing through the generator's cooling pipes, the heated air enters the reversing valve via the generator's outlet pipe and T-shaped pipe. Through the lower left and right ports of the reversing valve, it enters the main air pipe via the lower air pipe, and then from the main air pipe through the aeration pipe into the airlift system. The system uses filters for aeration and filtration; during this time, the air pressure inside the greenhouse rises, and exhaust is vented to the outside through the portholes. At night, the cooling switch is turned off, the reversing valve is lowered, the ventilation switch is closed, the aeration pump motor is turned on, the aeration pump is started, the electric heater switch is closed, and the electric heater resistance wire is turned on. Cold air from outside the greenhouse is filtered by the filter screen, heated by the electric heater, and then enters the reversing valve through the aeration inlet pipe. It then enters the main air pipe through the upper left and upper right interfaces of the reversing valve, and then enters the air-lift filter through the aeration pipe for aeration and filtration. During aeration and filtration, the air pressure inside the greenhouse rises, and exhaust is vented to the outside through the portholes. When the humidity and CO2 concentration inside the greenhouse are high, the ventilation volume can be controlled by adjusting the screw-in lifting rod to open the portholes and adjusting the opening angle of the portholes.

[0021] In summer, high water and air temperatures lead to significant evaporation and high oxygen consumption in the aquaculture and decomposition ponds. Opening the portholes and adjusting their angle improves ventilation and accelerates heat dissipation in the greenhouse. During summer operation, the electric heater switch is off, the reversing valve is lowered, and the exhaust valve is open. During the day, the cooling switch is closed to activate the cooling pump motor, starting the pump. Outside air, filtered through the filter, enters the generator's cooling pipes via the generator's intake pipe, ventilating and cooling the pipes. The heated air is then discharged directly into the atmosphere via the exhaust valve. When the ventilation switch is closed, the aeration pump is activated. Outside air, filtered through the filter, enters the reversing valve via the aeration intake pipe, then through the upper left and upper right interfaces of the reversing valve, and finally through the upper air pipe into the main air pipe. From there, it flows through the aeration pipe into the airlift filter for aeration and filtration. This process controls factors such as temperature, humidity, and CO2 levels. If the concentration is too high, the exhaust fan will be activated to exhaust the air. The washing machine's forward and reverse controller controls the exhaust fans on both sides of the greenhouse to alternately intake and exhaust air, forming a reciprocating gust of wind that stirs the air inside the greenhouse, making the air flow more even and thus improving the effects of ventilation, dehumidification, and cooling.

[0022] Compared with the existing technology, the present invention has the following advantages:

[0023] The generator of this invention can work around the clock and provide continuous power to the storage battery for a long time. The generator of this invention is a trolley-type concentrating photovoltaic generator, and the breeding shed is an arched transparent shed. In case of severe weather, the generator can be moved into the breeding shed to continue working.

[0024] The generator of this invention has a good overheat protection effect; the heat dissipation tube is a transparent glass tube that allows light to pass through directly and has little self-heating; the heat dissipation pump delivers air cooling to the heat dissipation tube through the generator's air inlet pipe, and the heat dissipation pump uses an axial flow fan to output cyclone air, which stirs inside the heat dissipation tube, resulting in uniform heat transfer.

[0025] This utility model's generator has high energy utilization and versatility. In winter, cold air from outside the greenhouse passes through the generator's heat dissipation pipe, and the heated air enters the reversing valve through the generator's outlet pipe and T-shaped pipe. From there, it enters the main air pipe through the lower air pipe, and then through the main air pipe and aeration pipe into the airlift filter for aeration and filtration. At this time, the air pressure inside the greenhouse rises, and the air is exhausted to the outside through the porthole. Power generation, aeration, and ventilation are all achieved in one step, making it a multi-purpose machine.

[0026] The generator of this utility model is a trolley-type concentrating photovoltaic generator. In case of severe weather, it can be promptly moved into a breeding shed or warehouse, which improves safety. The photovoltaic device does not require measures to prevent severe weather such as wind, frost, rain, snow, fog, hail, etc. during construction. While generating electricity continuously, it can also greatly reduce manufacturing and maintenance costs.

[0027] This invention provides a well-ventilated breeding shed. The portholes feature a louvered check valve structure, allowing for natural ventilation in winter while preventing cold air from entering the shed. The opening angle of the portholes can be adjusted by regulating the threaded extension rod to control the ventilation volume. In summer, exhaust fans can be activated to expel air. The washing machine's forward and reverse controller controls the exhaust fans on both sides of the shed to alternately intake and exhaust air, creating reciprocating gusts that stir the air inside the shed, making the airflow more uniform. This achieves ventilation, dehumidification, and cooling in one step, and is closer to natural ventilation.

[0028] This invention features low energy consumption. In winter, the exhaust gas heated by the generator's heat dissipation pipe can be fully utilized for aeration and ventilation of the breeding shed, effectively reducing the working time of the aeration pump and electric heater. In summer, the washing machine's forward and reverse controller controls the exhaust fans on both sides of the breeding shed to create reciprocating gusts, making the air flow inside the shed more uniform and reducing the working time of the exhaust fans. The intermittent operation of the exhaust fan motor also allows for more time for heat dissipation, which helps to improve the service life of the exhaust fan motor. Attached Figure Description
