Description

Technical Field

[0001] The invention relates to the technical field of freshwater fish breeding, and in particular to a photovoltaic-based land-based captive freshwater fish feeding system. Background Art

[0002] At present, the output of the aquaculture industry shows a trend of continuous growth. In the face of the ever-expanding demand for modern large-scale aquaculture, the traditional artificial aquaculture model is gradually becoming unable to cope with the demand. Compared with traditional aquaculture models such as ponds and cages, the land-based factory-based aquaculture model that has emerged in recent years has shown significant advantages. In the land-based factory-based aquaculture model, the cost of pellet feed plays a dominant role in the aquaculture cost, accounting for about 70% of the total cost. Overfeeding will cause excess feed to remain in the water, which will lead to deterioration of water quality and increased costs. Insufficient feed supply will inhibit the growth rate of the aquaculture objects and prolong the growth cycle.

[0003] The existing land-based factory farming method mainly relies on manual feeding and simple feeding equipment. These feeding devices have a low degree of automation and poor accuracy, resulting in a high rate of feed waste. In addition, these feeding equipment generally have high energy consumption, resulting in high electricity costs. In addition, a few land-based factory farming bases are established in remote areas with insufficient power grid coverage, which may cause power outages to the feeding equipment. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the present invention provides a photovoltaic-based land-based captive freshwater fish feeding system, which solves the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a photovoltaic-based land-based captive freshwater fish feeding system, comprising a captive barrel and a feeding assembly, a support frame is provided on the side of the captive barrel, the feeding assembly includes a storage bin arranged 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-material mixing pipe, an electric control box is provided between the captive barrels, the air inlet end of the air-material mixing pipe of each feeding device is connected to a gas branch pipe, and the end of the gas branch pipe away from the gas-material mixing pipe is connected to the gas transmission assembly through an electric valve, the gas transmission assembly includes a gas main pipe and a gas storage tank, the end of the gas main pipe is connected to the gas storage tank through a manual gas valve and a pressure regulating valve, and one side of the gas storage tank is connected to an air compressor through a pipeline.

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

[0007] Furthermore, the discharge end of the gas-material mixing pipe is located above the confinement barrel, and the number of the confinement barrels and the number of the gas-material mixing pipes are arranged one to one.

[0008] Furthermore, the electric control box is connected to the unloading equipment and the air compressor through wires, and the weighing sensor is wirelessly connected to the electric control box.

[0009] Furthermore, the electric control box and the air compressor are connected to a photovoltaic power generation system through wires, and the photovoltaic power generation system is arranged outdoors.

[0010] Furthermore, the photovoltaic-based land-based captive freshwater fish feeding system includes the following steps:

[0011] Step 1: The photovoltaic power generation system converts sunlight into electrical energy outdoors and converts it into a specified voltage through an inverter to supply the electrical control box and air compressor. The electrical control box then supplies power to the unloading equipment, weighing sensor and various electric valves through wires;

[0012] Step 2: Set the control box to manual feeding mode or automatic feeding mode according to needs, and add sufficient bait into the storage bin.

[0013] Furthermore, in the step 1, when the bait feeding operation is not performed, the air compressor still keeps operating to compress the air into the air storage tank for storage until the air storage in the air storage tank reaches the upper limit.

[0014] Furthermore, the photovoltaic-based land-based captive freshwater fish feeding system further includes the following steps:

[0015] Step 3: In manual feeding mode, manually select the enclosure barrel that needs to be fed in the electronic control box and start the feeding process. At this time, the weighing sensor in the feeding component corresponding to the enclosure barrel will feed back the weight of the bait inside the storage bin to the display screen in real time. At the same time, the feeding equipment is started to transport the bait inside the storage bin to the gas-feed mixing pipe. At the same time, the manual air valve and pressure regulating valve on the gas main are opened, so that the gas tank enters the corresponding gas-feed mixing pipe through the gas branch pipe after the opened electric valve, thereby pneumatically conveying the bait to the corresponding enclosure barrel, and manually stop the feeding process in time according to the real-time feedback of the remaining bait weight inside the storage bin.

[0016] Furthermore, the photovoltaic-based land-based captive freshwater fish feeding system further includes the following steps:

[0017] Step 4: In the automatic feeding mode, the feeding time interval, feeding amount and duration of each enclosure barrel are pre-set in the electronic control box. Then, when the preset feeding time is reached, the feeding equipment starts automatically to transport the bait inside the storage bin to the gas-feed mixing pipe. At the same time, the gas tank will let the internal gas enter the corresponding gas-feed mixing pipe along the gas main pipe and the opened gas branch pipe, so as to transport the bait to the corresponding enclosure barrel by pneumatic conveying, and automatically stop feeding when the remaining bait weight inside the storage bin reaches the preset amount according to the real-time feedback.

[0018] Furthermore, in step four, when the weighing sensor detects that the amount of bait inside the storage bin is lower than a preset value, the feeding operation is shut down and a buzzer is activated to sound an alarm, so as to prompt the staff to replenish the bait inside the storage bin in time.

[0019] The present invention provides a photovoltaic-based land-based captive freshwater fish feeding system, which has the following beneficial effects:

[0020] 1. This photovoltaic-based land-based captive freshwater fish feeding system adopts a photovoltaic power generation system to power the entire feeding system, and uses an air compressor and a gas tank as air supply components to realize pneumatic feeding. Among them, the gas tank is an energy storage component that stores the excess electricity of the photovoltaic power generation system in the form of air. The gas tank can not only serve as an energy storage component of the photovoltaic power generation system, 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. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0028] like Figure 1-Figure 5 As shown, the present invention provides a technical solution: a photovoltaic-based land-based captive freshwater fish feeding system, comprising a captive barrel 1 and a feeding assembly 3, a support frame 2 is provided on the side of the captive barrel 1, the feeding assembly 3 comprises a storage bin 301 arranged on the 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-material mixing pipe 304, an electric control box 4 is provided between the captive barrels 1, the air inlet end of the air-material mixing pipe 304 of each feeding device 303 is connected to a gas branch pipe 5, and the end of the gas branch pipe 5 away from the gas-material mixing pipe 304 is connected to a gas delivery assembly 6 through an electric valve, the gas delivery assembly 6 comprises a gas main pipe 601 and a gas storage tank 602, the gas main pipe 601 The end of the gas storage tank 602 is connected to the gas storage tank 602 through a manual air valve and a pressure regulating valve, and one side of the gas storage tank 602 is connected to the air compressor 603 through a pipeline. The feeding equipment 303 uses a star-shaped feeding device or a spiral feeding device, and the feeding equipment 303 is connected to the gas-material mixing pipeline 304, wherein the specific rotation of the star-shaped feeding device or the spiral feeding device is selected according to cost and use effect. The discharge end of the gas-material mixing pipeline 304 is located above the confinement barrel 1, and the number of confinement barrels 1 and the number of gas-material mixing pipelines 304 are arranged one to one. The electric control box 4 is connected to the feeding equipment 303 and the air compressor 603 through wires, and the weighing sensor 302 is wirelessly connected to the electric control box 4. The electric control box 4 and the air compressor 603 are connected to the photovoltaic power generation system 7 through wires, and the photovoltaic power generation system 7 is arranged outdoors;

[0029] The specific operation is as follows: the photovoltaic power generation system 7 cooperates with the inverter to convert external sunlight into electrical energy to drive the air compressor 603. In the idle state, the air compressor 603 can still keep working to compress the air into the gas tank 602 until the gas storage in the gas tank 602 reaches the upper limit. When feeding is required, the electric valve of the corresponding gas branch pipe 5 is opened, and the pressure regulating valve adjusts the gas transmission power of the gas tank 602 so that the gas enters the gas-material mixing pipe 304. At the same time, the unloading equipment 303 transports the bait inside the storage bin 301 to the gas-material mixing pipe 304. Under the action of pneumatic conveying, the bait inside the gas-material mixing pipe 304 is pushed into the confinement barrel 1. During the feeding process, the weighing sensor 302 detects the remaining amount of bait inside the storage bin 301 in real time, and stops the feeding operation after the feeding amount reaches the preset amount.

[0030] like Figure 1-Figure 5 As shown, the photovoltaic-based land-based captive freshwater fish feeding system includes the following steps:

[0031] Step 1: The photovoltaic power generation system 7 converts sunlight into electrical energy outdoors and converts it into a specified voltage through an inverter to supply power to the electrical control box 4 and the air compressor 603. The electrical control box 4 then supplies power to the unloading equipment 303, the weighing sensor 302 and the electric valves through wires;

[0032] When the bait feeding operation is not being performed, the air compressor 603 still keeps operating to compress the air into the air storage tank 602 for storage until the air storage tank 602 reaches the upper limit;

[0033] Step 2: Set the electric control box 4 to manual feeding mode or automatic feeding mode according to the needs, and add sufficient bait into the storage bin 301;

[0034] The main difference between manual mode and automatic mode is whether it can be started on time. Users can choose the bait casting mode by themselves.

[0035] Step 3: In the manual feeding mode, the person manually selects the enclosure barrel 1 that needs feeding in the electric control box 4 and starts the feeding work. At this time, the weighing sensor 302 in the corresponding feeding component 3 of the enclosure barrel 1 feeds back the weight of the bait inside the storage bin 301 to the display screen in real time. At the same time, the unloading device 303 is started to transport the bait inside the storage bin 301 to the gas-material mixing pipe 304. At the same time, the manual air valve and the pressure regulating valve on the gas main 601 are opened, so that the gas tank 602 enters the corresponding gas-material mixing pipe 304 through the gas branch pipe 5 after the open electric valve, thereby pneumatically conveying the bait to the corresponding enclosure barrel 1, and manually stops the feeding work in time according to the real-time feedback of the remaining bait weight inside the storage bin 301;

[0036] Step 4: In the automatic feeding mode, the feeding time interval, feeding amount and duration of each confined barrel 1 are pre-set in the electric control box 4. Then, when the preset feeding time is reached, the unloading device 303 automatically starts to transport the bait inside the storage bin 301 to the gas-material mixing pipe 304. At the same time, the gas tank 602 sends the internal gas along the gas main pipe 601 and the opened gas branch pipe 5 into the corresponding gas-material mixing pipe 304, thereby pneumatically conveying the bait to the corresponding confined barrel 1. The feeding work is automatically stopped when the weight of the remaining bait inside the storage bin 301 reaches the preset amount according to the real-time feedback;

[0037] When the weighing sensor 302 detects that the bait inside the storage bin 301 is lower than the preset value, the bait feeding operation is stopped and the buzzer is activated to sound an alarm to prompt the staff to replenish the bait inside the storage bin 301 in time;

[0038] This system uses the M8000 auxiliary relay inside the PLC to read the weighing indication, among which M8000 is RUN monitoring;

[0039] The weighing part includes a weighing sensor 302 and two weighing transmitters. The weighing subroutine needs to perform a cyclic scan 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 a pulse signal with a period of 100ms, that is, its state will switch back and forth between ON and OFF in each 100ms time interval.

[0040] Based on the above description, the present invention adopts a photovoltaic power generation system 7 to power the entire feeding system, and adopts an air compressor 603 and a gas tank 602 as air supply components to realize pneumatic feeding, wherein the gas tank 602 is used as an energy storage component to store excess electricity of the photovoltaic power generation system 7 in the form of air. The gas 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 air-delivered feeding system, thereby not only reducing environmental pollution, but also realizing the pneumatic feeding function of the photovoltaic feeding system.

[0041] In summary, when the photovoltaic-based land-based captive freshwater fish feeding system is used, the photovoltaic power generation system 7 converts sunlight into electrical energy outdoors and 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 equipment 303, the weighing sensor 302, and the electric valves through wires;

[0042] When the bait feeding operation is not being performed, the air compressor 603 still keeps working to compress the air into the gas tank 602 for storage until the gas storage in the gas tank 602 reaches the upper limit. Then, the electric control box 4 is set to the manual bait feeding mode or the automatic bait feeding mode according to the demand, and sufficient bait is added to the storage bin 301.

[0043] In the manual feeding mode, the user manually selects the enclosure barrel 1 to be fed in the electric control box 4 and starts the feeding process. At this time, the weighing sensor 302 in the corresponding feeding assembly 3 of the enclosure barrel 1 feeds back the weight of the bait inside the storage bin 301 to the display screen in real time. At the same time, the unloading device 303 is started to transport the bait inside the storage bin 301 to the gas-material mixing pipe 304. At the same time, the manual air valve and the pressure regulating valve on the gas main pipe 601 are opened, so that the gas tank 602 enters the corresponding gas-material mixing pipe 304 through the gas branch pipe 5 after the open electric valve, thereby pneumatically conveying the bait to the corresponding enclosure barrel 1. The feeding process is manually stopped in time according to the real-time feedback of the remaining bait weight inside the storage bin 301.

[0044] In the automatic feeding mode, the feeding time interval, feeding amount and duration of each enclosure barrel 1 are pre-set in the electric control box 4. Then, when the preset feeding time is reached, the unloading device 303 starts automatically to transport the bait inside the storage bin 301 to the gas-material mixing pipe 304. At the same time, the gas tank 602 sends the internal gas along the gas main pipe 601 and the opened gas branch pipe 5 into the corresponding gas-material mixing pipe 304, thereby pneumatically conveying the bait to the corresponding enclosure barrel 1, and automatically stops feeding when the weight of the remaining bait inside the storage bin 301 reaches the preset amount according to the real-time feedback.

[0045] The embodiments of the present invention are presented for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described in order to better illustrate the principles of the invention and its practical application and to enable those skilled in the art to understand the invention and design various embodiments with various modifications as suited for specific applications.
