Description

Technical Field

[0001] This invention relates to the field of marine aquaculture, and more particularly to an aquaculture device that helps protect the marine ecological environment. Background Technology

[0002] Marine aquaculture is an agricultural production method that utilizes nearshore waters such as shallow seas, tidal flats, harbors, and enclosures to artificially raise and breed marine economic plants and animals. With the expansion of marine aquaculture areas, the unreasonable farming methods and significant pollution generated during the production process have become a major cause of nearshore pollution.

[0003] Aquaculture pollution mainly includes nutrient contamination, drug contamination, and sediment enrichment during the aquaculture process. The pollution is primarily manifested in the excessive emissions of nitrogen (N), phosphorus (P), and chemical oxygen demand (COD) from aquaculture, exceeding the environmental carrying capacity and self-purification capacity of nearshore marine environments, leading to eutrophication and the resulting damage and abnormalities to the marine ecosystem. Different aquaculture species and farming methods produce varying levels of pollution and have different environmental impacts.

[0026] 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.

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Example 1:

[0028] Reference Figures 1 to 5 As shown, this embodiment provides an aquaculture device that helps protect the marine ecological environment, including an aquaculture tank 1. The top surface of the aquaculture tank 1 is open. An installation plate 3 is fixedly connected to the top surface of the aquaculture tank 1. A heating component is connected to the top surface of the installation plate 3 through an angle adjustment part. A photovoltaic component 6 is attached to the top surface of the heating component. The heating component is connected to a seawater evaporation component, which is connected to the bottom of the aquaculture tank 1. A light angle sensor is installed on the top surface of the photovoltaic component 6. A floating adjustment part is fixedly connected to the side wall of the aquaculture tank 1. The floating adjustment part is used to adjust the floating height of the aquaculture tank 1 to replenish the water volume in the aquaculture tank 1. The angle adjustment part, the light angle sensor, the photovoltaic component 6, and the floating adjustment part are electrically connected to a controller.

[0029] A light angle sensor is used to track the angle of sunlight. The photovoltaic module 6 can be connected to a battery. The battery and the photovoltaic module 6 work together to power the electrical components. The angle adjustment unit and the light angle sensor work together to adjust the angle of the photovoltaic module 6, allowing the photovoltaic module to better track sunlight and improve energy utilization. The heating component is set in close contact with the photovoltaic module 6 and can absorb excess heat during the operation of the photovoltaic module 6, which can improve the power generation efficiency of the photovoltaic module 6 and reduce the loss of the photovoltaic module 6. At the same time, the heating component provides a heat source for the seawater evaporation component, improving the efficiency of seawater evaporation. By connecting the seawater evaporation component to the bottom of the aquaculture tank 1, feed waste and seafood excrement in the aquaculture tank 1 are sent into the seawater evaporation component for evaporation. After evaporation, the cold distilled water is discharged into the seawater, reducing pollution to the ocean.

[0030] The design is further optimized. The angle adjustment unit includes a support rod 4 fixedly connected to the top surface of the mounting plate 3. The top end of the support rod 4 is ball-jointed to the center of the top adjustment plate 602. The heating component is located on the top surface of the top adjustment plate 602. At least three telescopic rods 5 are provided around the support rod 4. The ends of the telescopic rods 5 are ball-jointed to the bottom surface of the mounting plate 3 and the bottom surface of the top adjustment plate 602. The telescopic rods 5 are electrically connected to the controller. The mounting plate 3 is fixedly connected to the top surface of the breeding chamber 1 via the bracket 2.

[0031] The angle of sunlight is tracked by an angle light angle sensor, and the signal is transmitted to the controller. The controller controls the extension or retraction of the corresponding telescopic rod 5, which can control the angle of the top adjustment plate 602, thereby controlling the angle of the photovoltaic module 6 to align it with the sunlight.

[0032] The scheme is further optimized. The seawater evaporation component includes an evaporation shell 9, an evaporation chamber 901 is fixedly connected inside the evaporation shell 9, one side of the evaporation chamber 901 is connected to the bottom side wall of the aquaculture tank 1 through a waste discharge channel 8, a one-way valve is provided between the waste discharge channel 8 and the aquaculture tank 1, a condenser plate 902 is fixedly connected to the top of the evaporation shell 9, a gap is left between the side wall of the evaporation chamber 901 and the side wall of the evaporation shell 9 for the outflow of condensate from the condenser plate 902, an evaporation heating component is provided on the bottom wall of the evaporation chamber 901, the evaporation heating component is connected to the heating component, a gap is reserved between the evaporation heating component and the bottom wall of the evaporation shell 9, a distilled water discharge part is provided at the bottom of the evaporation shell 9, and the one-way valve is electrically connected to the controller.

[0033] By controlling the opening of the one-way valve, the waste material at the bottom of the aquaculture tank 1 enters the evaporator 901 through the flushing action of the seawater inside. The top of the evaporator 901 is set with an open structure. When the water level in the aquaculture tank 1 reaches the set level, the one-way valve is closed. At this time, the wastewater containing the waste material is distilled by the evaporation heating component. The condenser plate 902 can extend its end to the outside of the evaporator shell 9, so that it comes into contact with the seawater, thereby increasing the condensation capacity of the condenser plate 902. The condensate on the condenser plate 902 flows into the bottom of the evaporator shell 9 through the gap between the side wall of the evaporator 901 and the side wall of the evaporator shell 9, and is then discharged into the seawater through the distilled water discharge part, reducing the pollution of the seawater.

[0034] The scheme is further optimized. The evaporation heating component includes an evaporation pipe 903 coiled on the outside of the bottom of the evaporation box 901. The evaporation pipe 903 is connected to the heating component for circulation. The heating component includes a circulating heat collection pipe 601. The two ends of the circulating heat collection pipe 601 are connected to the two ends of the evaporation pipe 903 through a heat circulation pipe 10. A circulating water pump is provided on the heat circulation pipe 10. The circulating water pump is electrically connected to the controller.

[0035] The circulating water pump can be started at a fixed time for thermal circulation, or a temperature sensor can be installed on the evaporation pipe 903 or inside the evaporation box 901. The operation of the circulating water pump can be controlled by the temperature detected by the temperature sensor to ensure the effective evaporation of waste seawater in the evaporation box 901.

[0036] The scheme is further optimized. The distilled water discharge section includes a drain pump 904 located at the bottom of the evaporator 901. A drain channel 905 is provided on the upper part of the side wall of the evaporator shell 9. The liquid outlet of the drain pump 904 is connected to the drain channel 905. A drain check valve for outward discharge is provided on the drain channel 905. The drain pump 904 and the drain check valve are connected to seawater.

[0037] The height of the top surface of the evaporator 901 is not lower than the height of the seawater level in the aquaculture tank 1. The drain pump 904 can be operated in a fixed time mode, or the water level can be detected by installing a liquid level sensor in the evaporator shell 9. When the set water level is met, the controller controls the drain pump 904 to run and discharge the distilled water. The function of the drain check valve is to prevent seawater from flowing back into the evaporator shell 9.

[0038] The scheme is further optimized by installing a first liquid level sensor 106 on the inner wall of the breeding tank 1 and a second liquid level sensor 906 on the inner wall of the evaporator 901. The first liquid level sensor 106 and the second liquid level sensor 906 are electrically connected to the controller.

[0039] The first liquid level sensor 106 and the second liquid level sensor 906 are used in conjunction with the floating adjustment unit to control the water level in the aquaculture tank 1.

[0040] Further optimization of the design: the floating adjustment unit includes several floating airbags 7, which are arranged along the side wall of the aquaculture chamber 1. Each floating airbag 7 is connected to an air pump, which is electrically connected to a controller. A solenoid valve is installed on each floating airbag 7, and the solenoid valve is electrically connected to the controller.

[0041] The second liquid level sensor 906 detects that the water level in the evaporator 901 meets the requirements, and the first liquid level sensor 106 detects that the liquid level in the aquaculture chamber 1 is lower than the set requirements. At this time, the controller controls the solenoid valve to open, the floating airbag 7 deflates, the entire device sinks, and seawater enters from the top of the aquaculture chamber 1. When the liquid level in the aquaculture chamber 1 meets the requirements, the controller controls the solenoid valve to close. At this time, the controller controls the air pump to inflate the floating airbag 7, making the entire device float and stopping the seawater from entering. When the second liquid level sensor 906 detects that the water level in the evaporator 901 is lower than the evaporation requirement, the controller controls the one-way valve on the waste discharge channel 8 to open, replenishing the evaporator 901 with waste water. When the requirement is met, the controller controls the one-way valve on the waste discharge channel 8 to close.

[0042] The scheme is further optimized. The light angle sensor includes a mounting shell 11 fixedly connected to the top surface of the frame of the photovoltaic module 6. The bottom wall of the mounting shell 11 is provided with a number of photosensitive elements 1102, which are arranged in an array. The top wall of the mounting shell 11 has a light inlet hole 1101, which is an inverted conical structure. The photosensitive element 1102 located in the middle is correspondingly arranged with the light inlet hole 1101. The photosensitive element 1102 is electrically connected to the controller.

[0043] The photosensitive element 1102 can be a photodiode. The light inlet 1101 is set as an inverted conical structure, which can increase the incident angle range of the detected light. When the light is directly facing the photovoltaic module 6, the light shines on the photosensitive element 1102 in the middle through the light inlet 1101. When the light deviates, it will shine on the middle and adjacent photosensitive elements 1102 or only on the edge photosensitive elements 1102. At this time, the controller controls the corresponding telescopic rod 5 to extend or retract through the signal emitted by the photosensitive element 1102, so as to adjust the angle of the photovoltaic module 6.

[0044] The design has been further optimized by installing a waste cleaning mechanism inside the aquaculture tank 1. This mechanism is used to clean the waste from the bottom wall of the aquaculture tank 1 into the seawater evaporation components.

[0045] The waste cleaning mechanism includes two slides 103 on opposite inner side walls of the breeding chamber 1. A scraper 102 is slidably connected between the two slides 103. A guide wheel 104 is provided at the end of the slide 103. The guide wheel 104 is rotatably connected to the breeding chamber 1. One end of a pull rope 105 is fixedly connected to each of the two sides of the scraper 102. The pull rope 105 passes around the corresponding guide wheel 104 and is fixedly connected to the output shaft of the scraper motor 101. The scraper motor 101 is fixedly connected to the side wall of the breeding chamber 1 and is electrically connected to the controller. By controlling the rotation of the scraper motor 101, the scraper 102 can be moved to transport the waste at the bottom of the breeding chamber 1 into the evaporator 901. Example 2:

[0046] The only difference between the aquaculture device in this embodiment and the first embodiment is that a maintenance airbag 12 is installed at the bottom of the device. The maintenance airbag 12 is connected to an air pump. Like the floating airbag 7, the maintenance airbag 12 is equipped with a solenoid valve. When there are many crystals in the evaporation tank 901 that affect the evaporation efficiency, the maintenance airbag 12 can be inflated by the air pump to make the evaporation shell 9 float up and then clean the crystals in the evaporation tank 901. During maintenance, some seawater can be discharged from the aquaculture tank 1 to ensure that the aquatic products can survive. To reduce the buoyancy burden on the maintenance airbag 12, the controller can be set to no longer run the aforementioned control process during maintenance.
