Description

Technical Field

[0001] This utility model relates to the field of freshwater fish farming technology, specifically a photovoltaic-based land-based freshwater fish feeding system. Background Technology

[0002] Currently, the output of aquaculture is showing a continuous growth trend. Traditional artificial breeding models are gradually becoming inadequate in the face of the ever-expanding demand for modern large-scale aquaculture. Compared with traditional pond and cage aquaculture models, the land-based factory farming model that has emerged in recent years has shown significant advantages. In the land-based factory farming model, the cost of pelleted feed dominates the breeding cost, accounting for as much as 70% of the total cost. Overfeeding will result in excessive feed residue in the water, leading to water quality deterioration and increased costs; insufficient feed supply will inhibit the growth rate of the farmed organisms and prolong the growth cycle.

[0003] The existing domestic land-based factory farming feeding methods mainly rely on manual feeding and simple feeding equipment. These feeding devices have low automation and poor accuracy, resulting in a high feed waste rate. In addition, these feeding devices generally have high energy consumption, leading to high electricity costs. Furthermore, some land-based factory farming bases are located in remote areas with insufficient power grid coverage, which may result in power outages for the feeding equipment.

A support frame is provided on the side of the rearing tank. The feeding assembly includes a storage bin located on the top of the support frame, and a weighing sensor is provided on the side of the storage bin. A feeding device is provided at the bottom of the storage bin, and the discharge end of the feeding device is connected to an air-feed mixing pipe. An electrical control box is provided between the rearing tanks. The air inlet end of the air-feed mixing pipe of each feeding device is connected to an air supply branch pipe, and the end of the air supply branch pipe away from the air-feed mixing pipe is connected to an air supply assembly through an electric valve. The air supply assembly includes an air supply main pipe and an air storage tank. The end of the air supply main pipe is connected to the air storage tank through a manual air valve and a pressure regulating valve, and an air compressor is connected to one side of the air storage tank through a pipe.

[0006] Furthermore, the feeding device is a star-shaped feeding device or a spiral feeding device, and the feeding device is connected to the gas-material mixing pipeline.

[0007] Furthermore, the outlet end of the gas-material mixing pipe is located above the incubation tank, and the number of incubation tanks is set one-to-one with the number of gas-material mixing pipes.

Detailed Implementation

[0019] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0020] like Figures 1-5 As shown, this utility model provides a technical solution: a photovoltaic-based land-based freshwater fish feeding system, including a rearing tank 1 and a feeding assembly 3. A support frame 2 is provided on the side of the rearing tank 1. The feeding assembly 3 includes a storage bin 301 located on top of the support frame 2, and a weighing sensor 302 is provided on the side of the storage bin 301. A feeding device 303 is provided at the bottom of the storage bin 301, and the discharge end of the feeding device 303 is connected to an air-feed mixing pipe 304. An electrical control box 4 is provided between the rearing tanks 1. Each feeding device 303's air-feed mixing pipe 304 has an air supply branch pipe 5 connected to its air inlet end. The end of the air supply branch pipe 5 furthest from the air-feed mixing pipe 304 is connected to an air supply assembly 6 via an electric valve. The air supply assembly 6 includes a main air supply pipe 601 and an air storage tank 602. The end of 1 is connected to an air storage tank 602 via a manual air valve and a pressure regulating valve, and one side of the air storage tank 602 is connected to an air compressor 603 via a pipe. The feeding device 303 is selected as a star-shaped feeding device or a screw feeding device, and the feeding device 303 is connected to the air-material mixing pipe 304. The specific rotation of the star-shaped feeding device or the screw feeding device is selected based on cost and performance. The discharge end of the air-material mixing pipe 304 is located above the enclosure 1, and the number of enclosure 1 is set one-to-one with the number of air-material mixing pipes 304. The electrical control box 4 is connected to the feeding device 303 and the air compressor 603 via wires, and the weighing sensor 302 is wirelessly connected to the electrical control box 4. The electrical control box 4 and the air compressor 603 are connected to a photovoltaic power generation system 7 via wires, and the photovoltaic power generation system 7 is installed outdoors.

[0021] The specific operation is as follows: the photovoltaic power generation system 7, in conjunction with the inverter, converts external sunlight into electrical energy to drive the air compressor 603. In the idle state, the air compressor 603 can still work to compress air into the air storage tank 602 until the air storage tank 602 reaches its upper limit. When feeding is required, the electric valve of the corresponding air supply branch pipe 5 is opened, and the pressure regulating valve adjusts the air supply power of the air storage tank 602 so that the gas enters the gas-material mixing pipe 304. At the same time, the feeding device 303 transports the feed inside the storage bin 301 to the gas-material mixing pipe 304. Under the action of pneumatic conveying, the feed inside the gas-material mixing pipe 304 is pushed into the rearing bucket 1. During the feeding process, the weighing sensor 302 detects the amount of remaining feed inside the storage bin 301 in real time, and stops the feeding operation after the feeding amount reaches the preset amount.

[0022] like Figures 1-5 As shown, the photovoltaic-based land-based freshwater fish feeding system includes the following steps:

[0023] Step 1: The photovoltaic power generation system 7 converts sunlight into electrical energy outdoors and then converts it into a specified voltage through an inverter to supply the electrical control box 4 and the air compressor 603. The electrical control box 4 then supplies power to the feeding device 303, the weighing sensor 302 and various electric valves through wires.

[0024] When no feeding operation is being performed, the air compressor 603 continues to operate, compressing air into the air tank 602 for storage until the air tank 602 reaches its upper limit.

[0025] Step 2: Set the electrical control box 4 to manual or automatic feeding mode as needed, and add sufficient bait into the storage bin 301;

[0026] The main difference between manual and automatic modes is whether they can be started on a timer; users can choose the feeding mode themselves.

[0027] Step 3: In manual feeding mode, the operator selects the feeding bucket 1 in the control box 4 and starts the feeding operation. At this time, the weighing sensor 302 in the feeding component 3 corresponding to the feeding bucket 1 feeds the weight of the feed in the storage bin 301 to the display screen in real time. At the same time, the feeding device 303 starts to transport the feed in the storage bin 301 to the air-feed mixing pipe 304. At the same time, the manual air valve and pressure regulating valve on the main air pipe 601 are opened, so that the air tank 602 enters the corresponding air-feed mixing pipe 304 through the air branch pipe 5 after the open electric valve. Thus, the feed is transported to the corresponding feeding bucket 1 by pneumatic conveying. The operator stops the feeding operation in time according to the weight of the remaining feed in the storage bin 301 in real time.

[0028] Step 4: In automatic feeding mode, the feeding time interval, feeding amount, and duration of each feeding are preset in the electrical control box 4. Then, when the preset feeding time is reached, the feeding device 303 starts automatically to transport the feed inside the storage bin 301 to the gas-feed mixing pipe 304. At the same time, the gas tank 602 sends the internal gas through the main gas pipe 601 and the opened gas branch pipe 5 into the corresponding gas-feed mixing pipe 304, thereby transporting the feed to the corresponding feeding bin 1 through pneumatic conveying. The feeding operation will automatically stop when the weight of the remaining feed inside the storage bin 301 reaches the preset amount, based on the real-time feedback.

[0029] When the weighing sensor 302 detects that the amount of bait inside the storage bin 301 is lower than the preset value, the feeding operation is stopped and the buzzer is activated to alert the staff to replenish the bait inside the storage bin 301 in time.

[0030] This system uses the M8000 auxiliary relay inside the PLC to read the weighing reading. The M8000 is used for RUN monitoring.

[0031] The weighing section includes a weighing sensor 302 and two weighing transmitters. The weighing subroutine needs to scan cyclically between the two instruments. After querying the instrument parameters, the internal clock of M8012 is selected for cyclic scanning. M8012 is a 100ms pulse generator. M8012 generates pulse signals with a period of 100ms. That is, within each 100ms time interval, its state will switch back and forth between ON and OFF.

[0032] Based on the above description, this utility model uses a photovoltaic power generation system 7 to power the entire feeding system, and uses an air compressor 603 and an air storage tank 602 as air supply components to realize pneumatic feeding. The air storage tank 602 serves as an energy storage component, storing excess electricity from the photovoltaic power generation system 7 in the form of air. The air storage tank 602 can not only serve as an energy storage component of the photovoltaic power generation system 7, but also as an air supply component of the pneumatic feeding system. This not only reduces environmental pollution, but also realizes the pneumatic feeding function of the photovoltaic feeding system.

[0033] In summary, when this photovoltaic-based land-based freshwater fish feeding system is in use, the photovoltaic power generation system 7 first converts sunlight into electrical energy outdoors and then converts it into a specified voltage through an inverter to supply the electrical control box 4 and the air compressor 603. The electrical control box 4 then supplies power to the feeding device 303, the weighing sensor 302, and various electric valves through wires.

[0034] When no feeding operation is performed, the air compressor 603 continues to operate, compressing air into the air tank 602 for storage until the air tank 602 reaches its upper limit. Then, the electrical control box 4 is set to manual feeding mode or automatic feeding mode as needed, and sufficient bait is added into the storage bin 301.

[0035] In manual feeding mode, the operator selects the feeding bin 1 in the control box 4 and starts the feeding operation. At this time, the weighing sensor 302 in the feeding component 3 corresponding to the feeding bin 1 feeds the weight of the feed in the storage bin 301 to the display screen in real time. At the same time, the feeding device 303 starts to transport the feed in the storage bin 301 to the air-feed mixing pipe 304. At the same time, the manual air valve and pressure regulating valve on the main air pipe 601 are opened, so that the air tank 602 enters the corresponding air-feed mixing pipe 304 through the air branch pipe 5 after the open electric valve. Thus, the feed is transported to the corresponding feeding bin 1 by pneumatic conveying. The operator stops the feeding operation in time according to the weight of the remaining feed in the storage bin 301 in real time.

[0036] In automatic feeding mode, the feeding time interval, feeding amount, and duration of each feeding are preset in the electrical control box 4. Then, when the preset feeding time is reached, the feeding device 303 starts automatically to transport the feed inside the storage bin 301 to the gas-feed mixing pipe 304. At the same time, the gas tank 602 sends the internal gas through the main gas pipe 601 and the opened gas branch pipe 5 into the corresponding gas-feed mixing pipe 304, thereby transporting the feed to the corresponding feeding bin 1 through pneumatic conveying. The feeding operation automatically stops when the weight of the remaining feed inside the storage bin 301 reaches the preset amount, based on the real-time feedback.
