Description

Technical Field

[0001] This utility model relates to the field of oxygenation technology for freshwater fish farming ponds, specifically an emergency aeration device for freshwater fish farming ponds. Background Technology

[0002] Aerators are used as auxiliary oxygenation measures. They are mostly impeller-type, waterwheel-type, or microporous aeration devices, which are fixedly installed in the pond and rely on motor drive to achieve oxygenation of the entire pond. They are widely used in freshwater fish farming ponds to increase dissolved oxygen in the water by mechanically stirring, lifting, or blowing air. Some farmers use fixed pipes to spray water or manually turn on water pumps to supplement water and increase oxygenation during feeding. Early oxygenation methods were mainly fixed installations and full pond coverage, which maintained the dissolved oxygen level in the pond by promoting water flow and gas-liquid exchange. This provided the technical foundation and application experience for the subsequent development of mobile and precision spray aeration devices.

[0003] Power outages disrupt the power grid, rendering aerators inoperable and causing a continuous drop in dissolved oxygen in ponds. This can lead to fish surfacing for air or even suffocation and death, especially in high-density aquaculture conditions. On cloudy or rainy days, insufficient sunlight reduces phytoplankton photosynthesis, significantly decreasing oxygen production. Simultaneously, increased oxygen consumption due to organic matter decomposition further contributes to a rapid decrease in dissolved oxygen. In hot, humid weather or when air pressure drops sharply, oxygen solubility in the water decreases, creating an oxygen-deficient environment. Heavy rains cause convection between the upper and lower layers of pond water, with anaerobic water from the bottom rising and consuming large amounts of oxygen. During peak feeding periods, fish gather to feed, drastically increasing their oxygen consumption through respiration, causing a rapid drop in dissolved oxygen in localized areas. All these sudden events can cause a sharp decrease in dissolved oxygen in the water. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an emergency oxygenation device for freshwater fish farming ponds. It features dual pumps, four pipes, and multi-point spraying for oxygenation. The floating platform, combined with a self-moving and control module, allows for flexible movement and precise coverage of feeding points and oxygen-deficient areas. This solves the problem of sudden drops in dissolved oxygen during power outages, rainy days, hot and humid weather, heavy rain, or peak feeding times, which can easily lead to oxygen deficiency in fish and necessitate timely emergency oxygenation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an emergency stocking device for freshwater fish farming ponds, comprising a water pump and a control module, wherein two water pumps are provided and the water pumps and control module are located on the bank of the pond; it also includes a floating platform floating on the surface of the pond, wherein the input end of the water pump is connected to an inlet pipe and the other end of the inlet pipe extends into the pond, four main outlet pipes are provided on the floating platform, and the output end of the water pump is connected to a flexible connecting pipe, the other end of the flexible connecting pipe being connected to two main outlet pipes;

[0006] The main outlet pipe is a tubular structure extending along the axial direction. Multiple outlet holes are provided on the pipe wall. The outlet holes are distributed in the circumference and axial direction of the main outlet pipe, and the axis of the outlet holes is inclined downward relative to the horizontal plane. A self-moving device is provided at the lower end of the floating platform.

[0007] Furthermore, the self-moving device includes a thruster. When the thruster is powered on, it can drive the floating platform to move on the surface of the pond. The control module is electrically connected to the thruster. After receiving external signals, the control module outputs control commands to the thruster, causing the thruster to switch between running and stopped states.

[0008] Furthermore, the floating platform is composed of multiple high-density polyethylene pontoons spliced ​​together, and the high-density polyethylene pontoons are fixedly connected by metal connectors, and the overall structure of the floating platform is a rectangular frame.

[0009] Furthermore, the main water outlet pipe is a round pipe made of PVC material, the axial distance between adjacent water outlet holes is 15 centimeters, and the angle between the axis of the water outlet hole and the horizontal plane is 15 degrees.

[0010] Furthermore, the flexible connecting pipe is a rubber hose, and multiple auxiliary floats are fixedly connected to the outer wall of the rubber hose. The auxiliary floats are distributed at intervals along the length of the rubber hose. When the auxiliary floats float on the water surface, the flexible connecting pipe remains floating on the water surface.

[0011] Furthermore, the control module has multiple target coordinates pre-stored, and a positioning device is installed on the floating platform. The positioning device obtains the real-time coordinates of the floating platform, and the control module controls the thruster to operate based on the relative positional relationship between the real-time coordinates and any target coordinate, so that the floating platform moves from its current position to the position corresponding to the target coordinate.

[0012] Furthermore, it also includes a dissolved oxygen sensor, which is installed in the pond water and is connected to the control module. When the dissolved oxygen value detected by the dissolved oxygen sensor is lower than a preset threshold, the control module outputs a start signal to the thruster, causing the thruster to run and drive the floating platform to move.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] 1. By setting up two water pumps and four main water outlet pipes, a multi-point spray water flow is formed in the feeding area, which disperses the water into a large number of fine water droplets and sprays them into the air, significantly increasing the water-air contact area. Rapid physical aeration is achieved during the water flow reversal process, effectively improving the dissolved oxygen level of local water areas during peak feeding periods.

[0015] 2. The floating platform floats on the water surface and is equipped with a self-moving device. It can move along the pond water body under the coordinated action of the control module and the propeller, so that the spray area of ​​the main water outlet pipe is not limited by the fixed installation position and can be flexibly adjusted to different feeding points or areas prone to oxygen deficiency according to actual needs.

[0016] The technical problem to be solved by this utility model is that existing oxygenation devices are fixed in installation and cannot be moved flexibly, making it difficult to meet the local rapid oxygenation needs of feeding areas or sudden low-oxygen areas. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 This embodiment of an emergency aquaculture device for freshwater fish ponds includes a water pump 1 and a control module 8. Two water pumps 1 are provided, and the water pump 1 and control module 8 are located on the bank of the pond. It also includes a floating platform 3 that floats on the surface of the pond. The input end of the water pump 1 is connected to an inlet pipe 2, and the other end of the inlet pipe 2 extends into the pond. Four main outlet pipes 4 are provided on the floating platform 3. The output end of the water pump 1 is connected to a flexible connecting pipe 5, and the other end of the flexible connecting pipe 5 is connected to two main outlet pipes 4.

[0025] In this embodiment, multi-point spraying is achieved through the design of dual water pumps 1 and four pipelines, which increases the water-air contact area to improve dissolved oxygen. At the same time, the floating platform 3 can move with the cooperation of the self-moving device 7 and the control module 8, and the spraying position can be flexibly adjusted to different feeding points or hypoxic areas.

[0026] Please see Figures 1-5 In this embodiment, to disperse the water into fine sprays, which are then sprayed into the air and fall back down, allowing the water to absorb more oxygen and making it less prone to local oxygen deficiency during feeding, the main water outlet pipe 4 in this embodiment is a tubular structure extending along the axial direction. Multiple water outlet holes 6 are provided on the wall of the main water outlet pipe 4, distributed circumferentially and axially. The axis of the water outlet holes 6 is inclined downwards relative to the horizontal plane. A self-moving device 7 is provided at the lower end of the float 3. The main water outlet pipe 4 is a round pipe made of PVC material. The axial distance between adjacent water outlet holes 6 is 15 centimeters, and the angle between the axis of the water outlet holes 6 and the horizontal plane is 15 degrees. The flexible connecting pipe 5 is a rubber hose, and multiple auxiliary floats are fixedly connected to the outer wall of the rubber hose. The auxiliary floats are spaced apart along the length of the rubber hose. When the auxiliary floats float on the water surface, the flexible connecting pipe 5 remains floating on the water surface.

[0027] In this embodiment, the main outlet pipe 4 is made of PVC round pipe, which has good corrosion resistance and structural strength, and is easy to process and install. The main outlet pipe 4 is a tubular structure extending axially with multiple water outlet holes 6 on the pipe wall. The water outlet holes 6 are distributed circumferentially and axially in the main outlet pipe 4, so that the water flow is sprayed out from different directions. The axis of the water outlet hole 6 is inclined downward relative to the horizontal plane, and the included angle of 15 degrees is set to facilitate the water flow to spray at a certain angle to form a dispersed water spray. The axial distance between adjacent water outlet holes 6 is 15 cm to avoid mutual interference of the jets, so that the water is fully dispersed into fine water droplets and sprayed into the air to increase the contact area between water and air. During the fall, efficient oxygenation is achieved, which effectively alleviates the problem of excessive local oxygen consumption caused by the concentration of fish during feeding. The water pump 1 transports water to the main outlet pipe 4 through the flexible connecting pipe 5 (flexible connecting pipe 5). The connecting pipe 5 is connected to the main outlet pipe 4 via a quick-connect coupling. The flexible connecting pipe 5 is made of rubber hose with good flexibility and bending resistance. Multiple auxiliary floats are fixedly connected to the outer wall. The auxiliary floats are distributed at intervals along the length of the flexible connecting pipe 5 and float on the water surface, so that the flexible connecting pipe 5 is kept floating as a whole, preventing blockage or damage caused by sinking due to its own weight, and ensuring stable water delivery. The floating platform 3 is used to support the main outlet pipe 4 and connecting components and float on the water surface. The lower end of the floating platform 3 is equipped with a self-moving device 7, which includes a propeller that can drive the floating platform 3 to move in the pond under the action of a control signal. Combined with the control module 8 and the positioning device (the positioning device is a GPS module or a Beidou positioning module), the position can be adjusted so that the spraying area can flexibly cover different feeding points or low oxygen areas, improving the emergency oxygenation response capability and the operating range.

[0028] It should be noted that the control module 8 has multiple target coordinates pre-stored, and the floating platform 3 is equipped with a positioning device. The positioning device acquires the real-time coordinates of the floating platform 3. The control module 8 controls the propeller to operate based on the relative positional relationship between the real-time coordinates and any target coordinate, so that the floating platform 3 moves from its current position to the position corresponding to the target coordinate. The control module 8 is used to receive and process position information and issue control commands. It has multiple target coordinates pre-stored as the destination of movement. The positioning device on the floating platform 3 can acquire the current position data of the floating platform 3 in real time and transmit the data to the control module 8. The control module 8 compares and analyzes the real-time coordinates with the pre-stored target coordinates, generates corresponding motion control signals based on the relative positional relationship between the two, and outputs them to the propeller. The propeller starts running under the drive of the control signal, driving the floating platform 3 to move from its current position towards the target coordinate. Through this cooperation, the floating platform 3 achieves autonomous navigation and fixed-point arrival capability, enabling the spraying device to move to different areas as needed to perform oxygenation tasks, improving the flexibility and accuracy of equipment use, reducing manual intervention, and enhancing the rapid response capability to areas with oxygen deficiency risk in the pond.

[0029] Please see Figures 1-5 In this embodiment, to enable the entire water spray system to be mounted on a platform that can float on the water surface and move on its own according to instructions, going wherever it wants to aerate, the self-moving device 7 in this embodiment includes a propeller. When the propeller is powered on, it can drive the floating platform 3 to move on the surface of the pond. The control module 8 is electrically connected to the propeller. After receiving external signals, the control module 8 outputs control commands to the propeller, causing the propeller to switch between running and stopping states. The floating platform 3 is composed of multiple high-density polyethylene floats spliced ​​together. The high-density polyethylene floats are fixedly connected by metal connectors. The overall structure of the floating platform 3 is a rectangular frame.

[0030] In this embodiment, the floating platform 3 is composed of multiple high-density polyethylene floats, which have good buoyancy and water resistance. The high-density polyethylene floats are fixedly connected by metal connectors to ensure the overall structure is stable and reliable. The overall structure of the floating platform 3 is a rectangular frame, which can effectively support the main water outlet pipe 4 and related components and keep them floating stably on the water surface, providing a stable platform for the entire water spraying operation. The self-moving device 7 includes a thruster that can generate thrust when energized. The thruster is connected to the floating platform 3 so that its thrust acts on the floating platform 3, realizing the movement of the floating platform 3 on the pond water surface. The control module 8 is electrically connected to the thruster through wires. After receiving external remote control signals or preset commands, the control module 8 analyzes and processes them and outputs corresponding control commands to the thruster, so that the thruster switches between running and stopping states, or adjusts its running direction and speed. Through the coordinated work of the control module 8 and the thruster, the floating platform 3 can move autonomously to the designated area according to the commands, realizing flexible deployment and fixed-point operation, expanding the oxygenation coverage area, and improving the adaptability and ease of operation to meet the needs of different aquaculture areas.

[0031] It should be noted that a dissolved oxygen sensor is also included. The dissolved oxygen sensor is installed in the pond water and is connected to the control module 8. When the dissolved oxygen value detected by the dissolved oxygen sensor is lower than the preset threshold, the control module 8 outputs a start signal to the propeller to make the propeller run and drive the floating platform 3 to move. When the control module 8 receives the low oxygen signal from the dissolved oxygen sensor and drives the floating platform 3 to move, after the floating platform 3 stops moving, the control module 8 outputs a start signal to the water pump 1 to make the water pump 1 run.

[0032] The working principle of the above embodiments is as follows:

[0033] In use, high-density polyethylene pontoons are spliced ​​together with metal connectors to form a rectangular frame structure floating platform 3. The floating platform 3 floats stably on the water surface with the buoyancy provided by the pontoons, and is used to support the main water outlet pipe 4 and related components. The control module 8 receives external remote control signals or preset operating instructions, parses the instructions and generates corresponding control signals. The control module 8 transmits the control signals to the thruster through wires. After being powered on, the thruster starts to run according to the received signals, generating directional thrust. The thrust acts on the floating platform 3, causing it to start moving on the pond surface. The control module 8 adjusts the operating state of the thruster as needed, switching it between running and stopping, and controls the forward or reverse rotation of the thruster to change the moving direction and speed of the floating platform 3. Driven by the thruster, the floating platform 3 moves from the current position to the target area according to the instructions. After reaching the designated position, the control module 8 outputs a stop signal to stop the thruster. The floating platform 3 stays at the target position to perform water spraying operations. Through the above sequence, the controllable movement and fixed-point operation of the floating platform 3 are achieved, improving the flexibility and responsiveness of the equipment.

[0034] It should be noted that the control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming. The power supply is also common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail here.
