Description

Technical Field

[0001] The present invention relates to an aquaculture device, and particularly to a high-density aquaculture automation platform and a control method thereof. Background Art

[0002] Aquaculture in China is one of the fastest-growing industries in the Chinese agricultural structure. The aquaculture output still maintains stable growth, and 70% of the total world aquaculture output comes from China. During the aquaculture process, it is usually necessary to input bait. If the residual bait, excrement, and animal and plant corpses are not treated for water quality, it will lead to the deterioration of the water quality in the aquaculture pond, and finally the death of the aquaculture organisms, causing greater losses. However, most of the current aquaculture in China adopts the methods of flowing water and recycling of tail water that cannot be recycled, resulting in a low recycling rate of water resources. Therefore, it is necessary to accelerate the transformation of the aquaculture mode to enable sustainable aquaculture.

[0003] At present, the aquaculture method mostly uses canvas pond culture. However, due to the small water body and high culture density of the canvas pond, it is impossible to realize automatic sewage collection and discharge, resulting in an increase in harmful substances such as feces and residual bait in the water body, water quality deterioration, and a decrease in the dissolved oxygen content of the water body. In addition, the aquaculture wastewater is directly discharged without being recycled, causing serious pollution and resource waste of the natural water body and environment. Moreover, it is difficult to control the temperature of the water environment in the canvas pond. In cold or hot weather, it will lead to an increase in the mortality rate of aquatic organisms. Therefore, there is an urgent need to design a device and method that can realize automatic collection, treatment, recycling, and automatic temperature and oxygen control of aquaculture wastewater to solve the problems existing in current aquaculture. Summary of the Invention

[0004] The purpose of the present invention is to provide a high-density aquaculture automation platform and a control method thereof that utilize microelectronic technology and mechanical devices to realize automatic sewage collection, automatic sewage discharge, automatic temperature adjustment, automatic oxygen control, and automatic water cycle treatment in view of the deficiencies of the prior art.

[0005] The technical solution of the present invention is as follows:

[0006] An automated aquaculture platform with high density of the present invention includes a culture pond, and the culture pond is provided with an intelligent control main board, as well as a driving device, a main circulation pipe, a sewage discharge pipe and a water circulation treatment device connected to the intelligent control main board; the intelligent control main board controls the sewage collection device to be closed or working through the driving device; the lower end of the sewage collection device is connected with the main circulation pipe and the sewage discharge pipe, a flow control valve is arranged on the main circulation pipe, and a first sewage discharge switch is arranged on the sewage discharge pipe; the intelligent control main board is connected to drive the flow control valve and the first sewage discharge switch to be opened or closed; the water circulation treatment device includes a sewage treatment device, a water pump and a water inlet pipe, the water pump is arranged in the sewage treatment device and is connected to one end of the water inlet pipe, and the other end of the water inlet pipe is arranged above the water body of the culture pond; the sewage treatment device is communicated with the main circulation pipe.

[0007] Further, the sewage collection device includes a sewage collection buffer tank, a main circulation water inlet pipe, a limiting plate and a sliding cover plate are fixed above the sewage collection buffer tank, and the limiting plate restricts the upward movement of the sliding cover plate; one end of a spring is connected below the sliding cover plate, and the other end of the spring is installed in the sewage collection buffer tank; the water outlet at the lower end of the sewage collection buffer tank is connected with the sewage discharge pipe; the upper end of the sliding cover plate is connected with the driving device and moves up and down under the action of the timed pressure of the driving device and the elastic force of the spring; the main circulation water inlet pipe passes through the spring and is connected with the main circulation pipe, and water inlet small holes are arranged on the main circulation water inlet pipe.

[0008] In the above structure, the harmful substances discharged by the sewage collection device through the sewage discharge pipe do not enter the water circulation system and are directly discharged from the whole aquaculture system. The sewage flowing in through the main circulation water inlet pipe enters the sewage treatment device through the main circulation pipe for treatment, and then is pumped into the culture pond through the water pump and the water inlet pipe to realize the recycling of water circulation.

[0009] Further, the sewage treatment device includes an inclined plane filter, a biochemical bin, an ozone sterilization and precipitation bin and an EUV ultraviolet sterilization bin; the inclined plane filter is installed above the biochemical bin; two partition plates and water outlets are respectively arranged between the biochemical bin and the ozone sterilization and precipitation bin, and between the ozone sterilization and precipitation bin and the EUV ultraviolet sterilization bin, the water outlets are respectively arranged at different ends of the two partition plates, and a water flow channel is between the water outlets of the two partition plates; a water pump is arranged in the EUV ultraviolet sterilization bin.

[0010] The above structure ensures that after the sewage is treated by the inclined plane filter, it flows into the biochemical bin, and then flows into the ozone sterilization and precipitation bin and the EUV ultraviolet sterilization bin through the water outlet and the water flow channel for disinfection, sterilization and purification treatment.

[0011] Furthermore, a surface drainage system is provided in the aquaculture pond, which includes a water surface sewage discharge device, a surface drainage vertical pipe, and a surface drainage pipe. The water surface sewage discharge device is communicated with the upper end of the surface drainage vertical pipe. The lower end of the surface drainage vertical pipe passes through the main circulation water inlet pipe and is connected to the surface drainage pipe. A second drainage switch is provided on the surface drainage pipe. The water surface sewage discharge device is arranged on the water surface of the aquaculture pond, and the surface drainage pipe is arranged at the bottom of the aquaculture pond.

[0012] Furthermore, a water level sensor is provided in the aquaculture pond. The water level sensor is installed on the water surface of the aquaculture pond. The water level sensor includes a high-level probe and a low-level probe, and the high-level probe and the low-level probe are respectively connected to the intelligent control main board.

[0013] Furthermore, a temperature control, oxygen control, and automatic feeding device are provided in the aquaculture pond. The temperature and oxygen control device includes a temperature sensor, a heating plate, a cooling fan, a dissolved oxygen sensor, an aerator, and an aeration pipe, which are respectively connected to the intelligent control main board. The heating plate is arranged at the lower end of the bottom plate of the aquaculture pond. The temperature sensor, the dissolved oxygen sensor, and the aeration pipe are arranged in the water body of the aquaculture pond. The aeration pipe is connected to the aerator. The automatic feeding device includes a feeding machine and a storage bin, which are respectively connected to the intelligent control main board. The automatic feeding device is arranged beside the aquaculture pond, and the feeding port on the feeding machine is higher than the water surface.

[0014] The above structure oxygenates by generating an aeration effect through the micro-nano aeration pipe, and the water body continuously rotates around the center of the aquaculture pond. The harmful substances floating up by the air will gather in the form of bubbles around the water surface sewage discharge device.

[0015] Furthermore, a control method for a high-density aquaculture automatic breeding platform includes a circulating sewage collection and drainage control method: the intelligent control main board controls the sewage collection device to close through the driving device according to the set sewage discharge working time. When the sewage collection device reaches the specified closed position, the first sewage discharge switch is controlled to open. After the sewage discharge is completed, the first sewage discharge switch is closed. When the first sewage discharge switch is completely closed, the flow control valve on the main circulation pipe is opened. When the flow control valve is completely opened, the driving device controls the sewage collection device to open and enters the circulating sewage collection state.

[0016] Furthermore, a control method for a high-density aquaculture automatic breeding platform also includes a water circulation treatment control method: when the sewage collection device is opened, the first sewage discharge switch is closed, and the flow control valve is opened. The water in the sewage collection device flows into the sewage treatment system through the main circulation pipe. When the low-level probe of the water level sensor is triggered, the water pump is started to pump the water in the sewage treatment device into the aquaculture pond through the water inlet pipe.

[0017] Furthermore, a control method for a high-density aquatic automatic farming platform further includes a surface sewage collection and discharge control method: when the water in the sewage treatment device is pumped back into the farming pond and triggers the high-level probe of the water level sensor, the second sewage discharge switch of the surface drainage system is opened, and the intelligent control main board adjusts the flow control valve of the main circulation pipe so that the drainage volume of the main circulation pipe is less than the water intake volume of the water pump, resulting in a rising water level, making the water level higher than the water surface sewage discharge device, and the surface harmful substances are directly discharged from the farming pond through the surface drainage vertical pipe and the surface drainage pipe in the water surface sewage discharge device; when the water level drops so that the water surface is lower than the water surface sewage discharge device, a signal is sent to the intelligent control main board to control the second sewage discharge switch to close, and the flow control valve is fully opened. At this time, the water body circulation system operates normally, and the water surface sewage discharge device enters the sewage collection waiting period.

[0018] Furthermore, a control method for a high-density aquatic automatic farming platform further includes temperature control, oxygen control, and feeding control methods: the temperature sensor and the dissolved oxygen sensor in the farming pond collect the temperature and dissolved oxygen values in the farming pond in real time and send them to the intelligent control main board. The intelligent control main board determines whether each index is within the set value range. If it exceeds the range, it controls the operation of the heating plate, the cooling fan, and the aerator; the intelligent control main board sets the feeding time period to control the operation of the feeding machine.

[0019] Compared with the existing technology, the beneficial effects of the present invention are as follows:

[0020] 1. The present invention utilizes the continuous inflow of water to drive the water body to rotate along the center of the farming pond to generate centrifugal force and the water flow drop generated by the continuous drainage of the main circulation pipe to the outside, concentrating solid harmful substances such as the excrement and residual bait of aquatic animals at the bottom center of the aquaculture area. A sewage collection device and a sewage discharge device are arranged at the bottom center of the farming pond. By setting corresponding working time periods through the intelligent control main board, the sewage collection device is automatically controlled using microelectronics technology to achieve sewage collection and discharge treatment.

[0021] 2. The present invention is provided with a temperature control and oxygen control device, which uses a temperature sensor and a dissolved oxygen sensor to collect the water temperature and dissolved oxygen value in real time, compares them with the temperature value and dissolved oxygen value set by the intelligent control main board for the survival of suitable aquatic animals, and controls the operation of the heating plate, the cooling fan, the aerator, and the oxygenation pipe to achieve automatic temperature control and oxygen control.

[0022] 3. The present invention utilizes the water level drop of the water body in the farming pond, the water pump device, the water level sensor, and the intelligent control main board to circulate the water body in the farming pond, and uses the sewage treatment device to disinfect, sterilize, and purify the collected sewage, and then pumps the treated water into the farming pond to achieve an automatic water circulation farming mode.

[0023] 4. The present invention oxygenates water by generating an aeration effect through micro-nano oxygenation tubes. Meanwhile, tiny particles and harmful substances in the water body float to the water surface in the form of bubbles. A water level sensor including a high-level probe and a low-level probe is used. By using microelectronic technology, the flow control valve is automatically controlled to adjust at a specified time period, so that when the water level rises, it triggers the high-level probe to send a high-level signal to the intelligent control main board, controlling the opening of the second sewage discharge switch to discharge the surface harmful substances out of the water body through the surface drainage system; when the water level drops, it triggers the low-level probe to send a low-level signal to the intelligent control main board, and the intelligent control main board controls the water pump to pump water to realize the recycling of water circulation.

[0029] The technical solution of the present invention will be further described in detail below in conjunction with embodiments.

[0030] As Figure 1 shown, the present invention discloses a high-density aquaculture automation platform, which includes a culture pond 1.

The water pump 9 is arranged in the sewage treatment device 8 and is connected to one end of the water inlet pipe 10.

[0031] The sewage treatment device 8 includes an inclined plane filter 81, a biochemical tank 82, an ozone sterilization precipitation tank 83 and an EUV ultraviolet sterilization tank 84; the inclined plane filter 81 is installed above the biochemical tank 82; between the biochemical tank 82 and the ozone sterilization precipitation tank 83, and between the ozone sterilization precipitation tank 83 and the EUV ultraviolet sterilization tank 84, two partitions 14 and water outlets 15 are respectively arranged. The water outlets 15 are respectively arranged at different ends of the two partitions 14. The water flow channel is between the water outlets 15 of the two partitions 14; a water pump 9 is arranged in the EUV ultraviolet sterilization tank 84. After the sewage is treated by the inclined plane filtration, it flows into the biochemical tank, and then flows into the ozone sterilization precipitation tank and the EUV ultraviolet sterilization tank through the water outlet and the water flow channel for disinfection, sterilization and purification treatment.

[0032] The sewage treatment device 8 is connected to the main circulation pipe 61. The nozzle of the water inlet pipe 10 is arranged above the water body of the aquaculture pond 1. Due to the water level drop, when water flows into the aquaculture pond from the water inlet pipe, it will push the water body to rotate along the center of the aquaculture pond to generate centrifugal force. Since the aquaculture pond 1 includes an aquaculture area and a bottom hollow waterless area, the aquaculture area and the bottom hollow waterless area are separated by the aquaculture pond bottom plate 12, and an inclined bottom support 13 is arranged below the aquaculture pond bottom plate 12; the aquaculture pond bottom plate 12 is a funnel-shaped bottom plate, and the generated centrifugal force and the water flow drop generated by the continuous drainage of the main circulation pipe 61 will concentrate the feces, residual baits and solid harmful substances in the water body into the sewage collection device 4, and gather the harmful substances on the water surface that are floated up to the periphery of the water surface sewage discharge device 5.

[0033] The aquaculture pond 1 is provided with a temperature control, oxygen control and automatic feeding device. The temperature and oxygen control device includes a temperature sensor 71, a heating plate 73, a cooling fan 74, a dissolved oxygen sensor 72, an aerator and an aeration pipe respectively connected to the intelligent control main board 2; the heating plate 73 is arranged at the lower end of the aquaculture pond bottom plate 12, the temperature sensor 71, the dissolved oxygen sensor 72 and the aeration pipe are arranged in the aquaculture pond water body, and the aeration pipe is connected to the aerator; the automatic feeding device includes a feeding machine 16 and a storage bin 161 respectively connected to the intelligent control main board; the automatic feeding device is arranged beside the aquaculture pond, and the feeding port 162 on the feeding machine is higher than the water surface. According to the relevant living habits of the aquaculture animals, the feeding time and feeding quantity are set for the intelligent control main board. When the system runs to the specified cycle, the intelligent control main board starts the feeding machine to achieve automatic feeding.

[0034] The aquaculture pond 1 is also provided with a water surface sewage discharge device 5, a surface drainage vertical pipe 64 and a surface drainage pipe 63. The water surface sewage discharge device 5 is connected to the upper end of the surface drainage vertical pipe 64. The lower end of the surface drainage vertical pipe 64 passes through the main circulation water inlet pipe 60 and is connected to the surface drainage pipe 63. A second drainage switch 631 is arranged on the surface drainage pipe 63. The water surface sewage discharge device 5 is arranged on the water surface of the aquaculture pond, and the surface drainage pipe 63 is arranged at the bottom of the aquaculture pond. The surface harmful substances discharged from the surface drainage pipe 63 are directly discharged from the aquaculture pond.

[0035] The aquaculture pond 1 is also provided with a water level sensor 11. The water level sensor 11 is installed on the water surface of the aquaculture pond. The water level sensor 11 also includes a high-level probe and a low-level probe. The flow control valve 611 is adjusted through the intelligent control main board 2 at a specified time period, so that when the water level rises, the high-level probe is triggered to send a high-level signal to the intelligent control main board 2 to open the second sewage discharge switch 631; when the water level drops, the low-level probe is triggered to send a low-level signal to the intelligent control main board 2, and the intelligent control main board 2 controls the water pump 9 to pump water.

[0036] Such as Figure 2As shown in the figure, the sewage collection device 4 includes a sewage collection buffer tank 44, a main circulation water inlet pipe 60. Above the sewage collection buffer tank 44, a limit plate 41 and a sliding cover plate 42 are fixed. The limit plate 41 restricts the upward movement of the sliding cover plate 42. One end of a spring 43 is connected to the lower part of the sliding cover plate 42, and the other end of the spring 43 is installed in the sewage collection buffer tank 44. The water outlet at the lower end of the sewage collection buffer tank 44 is connected to a sewage discharge pipe 62. The upper end of the sliding cover plate 42 is connected to a driving device 3, and it moves up and down under the action of the timed pressure of the driving device 3 and the elastic force of the spring 43. The main circulation water inlet pipe 60 passes through the spring 43 and is connected to the main circulation pipe 61, and water inlet small holes 45 are arranged on the main circulation water inlet pipe 60.

[0037] As Figure 3 shown in the figure, the driving device 3 includes a motor or a cylinder 31, a motor or cylinder fixed seat 32, a connecting seat 33, a slider 34, a lead screw or a cylinder piston rod 35, a fixed rod 36 and a support rod 37. The motor or cylinder 31 is installed on the motor or cylinder fixed seat 32. At the other end of the motor or cylinder fixed seat 32, a connecting seat 33 is further provided. A motor or cylinder piston rod 35 is installed on the connecting seat 33. The lead screw or cylinder piston rod 35 passes through the slider 34 and is connected to a fixed plate. The lower end of the fixed plate is connected to a support rod 37. The upper end of the fixed rod 36 is connected to the slider 34, and the lower end of the fixed rod 36 passes through the limit plate 41 and is connected to the sliding cover plate 42.

[0038] Control method:

[0039] Circulating sewage collection and discharge control method: Under normal conditions, the sliding cover plate 42 of the sewage collection device 4 is opened upward at the limit plate 41 defined on the sewage collection device due to the upward elastic force of the spring 43. At this time, the sewage collection device 4 is opened; due to the water level drop, part of the water at the bottom of the aquaculture pond enters the sewage collection buffer tank 44 and flows outwards through the water inlet holes 45 on the main circulation water inlet pipe 60 into the main circulation pipe 61 for circulation. The generated water flow drives the solid feces, residual baits and harmful substances in the water body to flow into the sewage collection buffer tank. At this time, the first sewage discharge switch 621 on the sewage discharge pipe is in the closed state; the intelligent control main board 2 designed by microelectronics technology sets a certain time period. When the specified time period arrives, the intelligent control main board 2 sends out an instruction to close the flow control valve 611 on the main circulation pipe 61. When the intelligent control main board 2 collects that the flow control valve 611 is completely closed, the intelligent control main board 2 issues an instruction to drive and start the motor or cylinder 31, applying a downward force to the sliding cover plate 42 of the sewage collection device, so that the sliding cover plate 42 moves downward to reach the upper end of the sewage collection device 4, closing the sewage collection device 4; when the sliding cover plate 42 reaches the specified closing position, the intelligent control main board controls the first sewage discharge switch 621 on the sewage discharge pipe 62 to open, directly discharging the sewage with solid feces, residual baits and harmful substances in the sewage collection device 4 from the aquaculture system. After the sewage discharge is completed, an instruction to close the first sewage discharge switch 621 is sent out through the intelligent control main board 2. When the intelligent control main board 2 collects the signal that the first sewage discharge switch 621 is completely closed, the flow control valve 611 on the main circulation pipe 61 is opened. When the intelligent control main board 2 collects that the flow control valve 611 is completely opened, the intelligent control main board 2 issues an instruction to drive the motor or cylinder 31 in the reverse direction to open the sewage collection device. The water body enters the circulating sewage collection state again.

[0040] Water cycle treatment control method: The sewage treatment device 8 is lower than the breeding pond 1. The sewage discharged from the main circulation pipe 61 enters the biochemical chamber 82 through the inclined surface filtration 81 of the sewage treatment device 8 for nitrification treatment. Since when the sewage collection device (4) is opened, the first sewage discharge switch (621) is closed and the flow control valve (611) is opened, water continuously enters the biochemical chamber 82. The water treated in the biochemical chamber 82 flows into the ozone treatment chamber 83 through the water flow channel between the water outlet 15 at the lower right and the two partitions 14 for disinfection and sterilization treatment. The water treated in the ozone treatment chamber 83 continues to flow into the EUV ultraviolet sterilization chamber 84 through the same way for disinfection, sterilization treatment and precipitation; when the low-level probe of the water level sensor in the breeding pond is triggered, the water pump 9 at the lower right of the EUV ultraviolet sterilization chamber 84 is controlled to start, and the water that has been disinfected, sterilized and purified is pumped back into the breeding pond 1 through the water inlet pipe 10 for water cycle. The direction of the water inlet pipe opening is adjusted at a certain angle with respect to the edge of the breeding pond water body, so that while continuously feeding water, it promotes the water body to rotate around the center of the breeding pond to generate centrifugal force. The centrifugal force generated causes feces, residual baits and other solid harmful substances to concentrate in the sewage collection buffer tank 44 and wait to be discharged from the breeding pond at the next sewage discharge time. The entire water cycle process is automatically controlled by the intelligent control main board designed by microelectronic technology for 24 hours without interruption for sewage collection, sewage discharge, water treatment and circulating pumping.

[0041] Surface sewage collection and discharge control method: When the water body is circulating normally, when the high-level probe of the water level sensor is triggered when the water in the sewage treatment device is pumped back into the breeding pond, the second sewage discharge switch 631 of the surface drainage system is opened; since the water body is aerated through the micro-nano aeration pipes distributed at the bottom of the water body, and the water body continuously rotates around the center of the breeding pond, the tiny harmful substance particles floating up by air will gather in the form of bubbles around the sewage discharge device 5 on the water surface. The intelligent control main board 2 adjusts the flow control valve 611 of the main circulation pipe so that the drainage volume of the main circulation pipe is less than the water inlet volume of the water pump, resulting in the water level rising, making the water level higher than the sewage discharge device on the water surface. At this time, the harmful substances floating up by air overflow through the sewage discharge device 5 on the water surface and are discharged from the system through the surface drainage vertical pipe 64 and the surface drainage pipe 63. When the water level drops so that the water surface is lower than the sewage discharge device on the water surface, a signal is sent to the intelligent control main board to control the second sewage discharge switch 631 to close, and the flow control valve 611 of the main circulation pipe is fully opened. At this time, the water body circulation system operates normally, and the sewage discharge device on the water surface enters the sewage collection waiting period.

[0042] Temperature and oxygen control and feeding control method: Since the intelligent control main board 2 has the function of collecting the water temperature in real time through the temperature sensor 71 and is connected to the heating plate 73, when the water temperature of the water body is lower than the set temperature value, the heating plate 73 is turned on to heat the water body. When the water temperature of the water body is higher than the set temperature value, the heating plate 73 is turned off and the cooling fan 74 is turned on for heat dissipation, so that the water body is at a constant temperature, improving the breeding efficiency and preventing some diseases and pests, etc. At the same time, the intelligent control main board 2 has the function of collecting the dissolved oxygen value of the water body in real time through the dissolved oxygen sensor 72 and is connected to the aerator. When the dissolved oxygen is lower than the set dissolved oxygen value, the aerator is turned on to increase the oxygen in the water body through the oxygenation pipe. When the dissolved oxygen value of the water body is higher than the set dissolved oxygen value, the aerator is turned off to prevent the fish from suffering from bubble disease due to too high dissolved oxygen in the water body, etc. An automatic feeding device is arranged beside the breeding pond, and the feeding time and feeding quantity can be set for the intelligent control main board according to the relevant living habits of the aquaculture animals. When the system runs to the specified cycle, the intelligent control main board starts the automatic feeding device to realize automatic feeding.

[0043] The above embodiments only represent the specific implementation manners of the present application, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the protection scope of the present application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the technical solution of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application.
