[0022] Reference Figures 1 to 3An aquaculture oxygenation device according to an embodiment of the present invention includes a frame 100 and a control device. The frame 100 is equipped with a float 101, an oxygenation device 110, a photovoltaic device 120, and a power unit 140. The oxygenation device 110 includes a water pump 111, and the photovoltaic device 120 includes a swing mechanism 121 and a photovoltaic panel 131. The swing mechanism 121 is mounted on the frame 100 and can adjust the rotation angle and pitch angle of the photovoltaic panel 131. The power unit 140 includes a propeller 142 disposed at one end of the float 101. When the propeller 142 rotates, the float 101 can move on the water surface, thereby adjusting the position of the oxygenation device in the aquaculture pond. This allows oxygenation to be performed at different locations, which is beneficial for increasing the oxygen content of the water. Furthermore, the photovoltaic panel 131 provides solar power supply, eliminating the need for power lines, making installation and adjustment easier for workers and improving flexibility. The control device includes a light sensor and a posture sensor. The light sensor is installed on the swing mechanism 121. The posture sensor can measure the movement acceleration and rotation angle of the rack 100. When the rack 100 moves or rotates, the control device can use the feedback of the light sensor and the posture sensor to enable the swing mechanism 121 to drive the photovoltaic panel 131 to move, so that sunlight can directly hit the photovoltaic panel 131, which is conducive to ensuring good photovoltaic efficiency, reducing energy consumption, and improving the continuous oxygen supply capacity of the oxygen enrichment equipment, thereby increasing the oxygen content of the water body.
[0023] Specifically, the frame 100 serves as the core support structure and is typically welded from lightweight aluminum alloy or corrosion-resistant steel. Long, strip-shaped floats 101 are symmetrically mounted on either side of its bottom. The floats 101 are made of high-density polyethylene or expanded polystyrene to ensure sufficient buoyancy to support the entire device. It is understood that the length of the floats 101 is consistent with the length of the frame 100. The head 102 is designed as a streamlined structure with inclined surfaces 104 on both sides to reduce surface resistance. The tail 103 is equipped with a propeller 142 of the power unit 140. When the propeller 142 is driven by a motor, it propels the float 101 across the water, enabling the device to move or autonomously position itself within the aquaculture pond.
[0024] It is understood that the oxygenation device 110 includes a water pump 111, an air tank 112, a water inlet pipe 114, and a water outlet pipe 115. The water pump 111 is preferably a submersible pump 111 or a centrifugal pump, and the water pump 111 is fixed to the middle of the frame 100. The water inlet pipe 114 extends vertically from the bottom of the frame 100 into the water. Its bottom end is provided with a conical head 116. The small end of the conical head 116 is connected to the water inlet pipe 114, and the large end of the conical head 116 is located at the end away from the water inlet pipe 114. The conical head 116 can enhance the efficiency of water intake. Furthermore, the large end of the conical head 116 is provided with a screen (not shown in the figure) to prevent foreign matter such as garbage from entering the water inlet pipe 114, thereby preventing blockage.
[0025] It will be appreciated that the water outlet pipe 115 is arranged horizontally above the frame 100 and has multiple evenly spaced water outlets 117 along its width. Furthermore, multiple guide pipes 118 are provided on the water outlet pipe 115. In this embodiment, the length of the guide pipes 118 is perpendicular to the length of the water outlet pipe 115 and parallel to the length of the float 101, thereby discharging water in the direction of travel away from the frame 100.
[0026] It is understood that the oxygenation device 110 also includes an air tank 112, which is connected to the water pump 111 via an air pipe 113. The air pipe 113 is connected to the side of the water outlet pipe 115 that faces away from the water outlet 117. After high-pressure air is injected into the water flow through the air pipe 113, a large number of microbubbles are formed, which can significantly improve the dissolved oxygen efficiency. In practical applications, a gas-liquid mixer or a Venturi tube can also be added to further refine the bubbles. It is understood that the air tank 112 can be used to store high-pressure air or oxygen, which can increase the oxygen content of the water.
[0027] It is understood that the photovoltaic device 120 is composed of a photovoltaic panel 131 and an oscillating mechanism 121. The oscillating mechanism 121 includes a base 122, a stand 123, and a turntable 126. The frame 100 also has a mounting frame 105, which is equipped with a drive shaft 128 and a belt 129. The belt 129 is wrapped around the outer circumference of the drive shaft 128. The base 122 is fixed to the upper portion of the frame 100 via the mounting frame 105. A first motor 124 is installed at the bottom of the mounting frame 105. The first motor 124 drives the drive shaft 128 to rotate through the belt 129, thereby driving the turntable 126 to rotate horizontally, achieving azimuth adjustment of the photovoltaic panel 131 between 0 and 360 degrees.
[0028] As will be understood, the stand 123 is mounted perpendicular to one side of the base 122 and contains a screw 127 driven by a second motor 125. A connecting frame 130 is provided between the photovoltaic panel 131 and the stand 123. One end of the connecting frame 130 is pivotally connected to the photovoltaic panel 131, and the screw 127 is threadedly engaged with one end of the connecting frame 130. When the screw 127 rotates, the connecting frame 130 moves up and down along the stand 123, driving the photovoltaic panel 131 to change its pitch angle around the pivot on the other side of the base 122. This dual-degree-of-freedom adjustment structure can adapt to real-time changes in the solar altitude and azimuth angles.
[0029] It is understandable that the power unit 140 also includes a mounting base 141 installed on the tail 103 of the float 101, the mounting base 141 is detachably mounted on the tail 103 of the float 101, and the propeller 142 is arranged on the mounting base 141. Furthermore, in addition to the propeller 142, the power unit 140 also includes a matching drive motor and a reducer. The propeller 142 is preferably a three-blade or five-blade design, and the blade angle is adjustable to meet the requirements of different water depths. In shallow water areas, a low-speed and high-torque configuration can be adopted, and in deep water areas, a high-speed mode is switched. In order to enhance maneuverability, a rudder or a vector thruster can be installed at the tail 103 of the float 101 to achieve more precise path control.
[0030] It is understandable that the control device integrates a light sensor, a posture sensor and a microprocessor. The light sensor is embedded in the edge of the photovoltaic panel 131 to monitor the light intensity and incident angle in real time. The posture sensor uses a combination of a MEMS accelerometer and a gyroscope to detect the position offset, tilt angle and motion acceleration of the frame 100. When the equipment moves or its posture changes due to the influence of wind and waves, the control device integrates the two types of sensor data through an algorithm and dynamically adjusts the two motor actions of the swing mechanism 121 so that the photovoltaic panel 131 is always perpendicular to the direction of direct sunlight. For example, when the equipment moves eastward, the posture sensor detects the direction of acceleration, and the light sensor synchronously feeds back the light changes. The control device calculates the compensation angle and drives the turntable 126 to rotate, while adjusting the screw 127 to lift the photovoltaic panel 131 to ensure maximum power generation efficiency.
[0031] Furthermore, because one end of the photovoltaic panel 131 is height-adjustable, it can be folded when the connecting frame 130 reaches its lowest point, folding to a horizontal position in inclement weather to reduce wind resistance. The control device can also be connected to a wireless communication module, supporting remote monitoring and route planning. Users can set the trajectory of the oxygen enrichment zone through a mobile phone app.
[0032] The equipment installation process is as follows: First, bolt the float 101 to the frame 100, check the overall balance, and then place it in water. Adjust the water pump 111's water inlet depth to 0.5-1 meter below the water surface. Secure the swing mechanism 121 with the mounting bracket 105 and calibrate the initial angle of the photovoltaic panel 131. Finally, power on the system to test the control system's sensor feedback and actuator linkage. During daily operation, the equipment can move along a pre-set cruise route or automatically navigate to low-oxygen areas based on dissolved oxygen sensor feedback. At night or in rainy weather, the high-pressure air stored in the air tank 112 can provide continuous oxygen supply for several hours.
[0033] Compared to traditional fixed aerators, this implementation is innovative in three ways: First, through an integrated photovoltaic-power design, it combines energy self-sufficiency with mobile oxygenation, solving the problem of uneven dissolved oxygenation in large-scale aquaculture ponds. Second, a multi-sensor fusion intelligent tracking system ensures that the photovoltaic panels 131 maintain optimal light-receiving posture even when the device is in motion, improving power generation efficiency by over 30%. Third, its modular design allows for the rapid replacement of water pumps 111 or photovoltaic panels 131 with different power levels, adapting to the needs of various aquaculture scenarios, such as fish and shrimp ponds. Experimental data shows that when used in a 20-mu aquaculture pond, this device can maintain a stable dissolved oxygen level of over 5 mg / L while reducing cabling costs by 70%.
[0034] The control system incorporates a multi-level warning system for fault protection. If the photovoltaic panels 131 detect a 30-minute period of ineffective power generation, the system automatically switches to backup battery power and issues an alert. If the attitude sensor detects a tilt exceeding 15° on the frame 100, the propellers 142 are immediately stopped to prevent rollover. The air tank 112 is equipped with a safety valve and pressure sensor to automatically shut off the air supply in the event of abnormal pressure. Furthermore, all electrical components meet IP68 waterproofing standards, and key connections are protected with stainless steel fasteners and sealant.
[0035] Further application scenarios include: linking with a feeding machine to achieve precise feeding while simultaneously increasing oxygen; adding water quality monitoring probes to become a mobile monitoring platform; and acting as an emergency device to create circulation in algae bloom areas to suppress algal blooms. By replacing the dedicated float 101, this system can also be expanded to ecological restoration projects in natural water bodies such as lakes and reservoirs.
[0036] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the scope of the present invention.
