Description

Technical Field

[0001] This invention relates to the field of fish aquaculture and breeding technology, specifically a composite green ecological aquaculture equipment. Background Technology

[0002] Fish aquaculture breeding equipment is a facility that integrates aquaculture science, ecology, mechanical engineering and automation control. It is designed to simulate or optimize the natural breeding environment of fish and improve the spawning rate, fertilization rate, hatching rate and seedling survival rate.

[0003] In the current use of fish aquaculture equipment, bottom cleaning is mostly done manually or periodically with electric suction pumps, which requires additional power and human intervention. At the same time, the direct discharge of aquaculture wastewater causes water waste and environmental pollution. There is a lack of green circular treatment that combines the resource utilization of fish manure with water purification.

[0004] To address the aforementioned issues, we propose a composite green ecological aquaculture equipment. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a composite green ecological aquaculture equipment. In this equipment, the buoyancy block utilizes the natural undulations of the water surface as the sole driving force. By connecting the vertical plate and the rotating plate, it drives the rotating shaft to swing back and forth, achieving energy-saving self-driven cleaning without an external power source. Furthermore, the rotating shaft is connected to the second helical gear through a one-way bearing, converting the reciprocating swing into the one-way intermittent rotation of the first helical gear, ensuring that the cleaning component always rotates in a single direction to scrape and collect fish feces.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a composite green ecological aquaculture equipment, including an aquaculture pond, a composite aquaculture trough plate fixedly installed on the top of the aquaculture pond, purification troughs opened on both the left and right sides of the bottom of the composite aquaculture trough plate, and a power vertical rod rotatably installed at the center of the bottom of the composite aquaculture trough plate, and purification components provided on the inner walls of both purification troughs; The bottom of the composite aquaculture trough is rotatably mounted on the periphery of the power vertical rod. A first helical gear is fixedly mounted on one side of the inner wall of the power vertical rod located on the protective shell. Three power components are arranged around the periphery of the first helical gear. A connecting column is embedded in the lower side of the inner wall of the aquaculture tank, and a connecting pipe is rotatably installed on the top of the connecting column. A water pump is fixedly installed on the left side of the top of the composite aquaculture trough plate, and a cleaning component is provided on the wall of the connecting pipe.

[0007] Furthermore, a protective ring is fixedly installed on the top of the aquaculture pond around the perimeter of the composite aquaculture trough, and protective fences are fixedly installed on both the front and back sides of the surface of the composite aquaculture trough.

[0008] Furthermore, the purification assembly includes a filter plate snapped onto the rear side of the inner wall of the purification tank. A partition mesh plate is fixedly installed on the upper side of the inner wall of the filter plate. The top of the partition mesh plate is used to place filter cotton plates for fine filtration. The bottom of the filter plate is used to fill biological filter media to purify the water. The left and right sides of the inner wall of the filter plate are provided with ventilating inclined holes located below the partition mesh plate. The ventilating inclined holes are used to allow the water purified by nitrifying bacteria in the filter plate to overflow. The width of the filter plate is smaller than the width of the purification tank so that the purified water flows into the aquaculture pond.

[0009] Furthermore, the upper side of the inner wall of the purification tank is provided with several vertical penetration holes inside the filter tank plate. Each vertical penetration hole has a barrier net fixedly installed on both the upper and lower sides of its inner wall. The barrier net is used to prevent the nutrient soil in the composite aquaculture tank plate from entering the purification tank.

[0010] Furthermore, the power assembly includes a second helical gear meshing with the surface of the first helical gear, and the inner wall of the second helical gear is connected to a rotating shaft via a one-way bearing, with support blocks rotatably connected to both ends of the rotating shaft; Rotating plates are fixedly installed on both sides of the rotating shaft wall opposite to the second helical gear. The inner wall of the protective shell has an opening on one side of the two rotating plates. The lower ends of the two rotating plates are rotatably connected to connecting vertical plates, and the bottom of the two connecting vertical plates are fixedly installed with buoyancy blocks.

[0011] Furthermore, the bottom of the support block is fixedly connected to the lower side of the inner wall of the protective shell, one end of the two rotating plates extends to the outside of the protective shell through the movable opening, and the rotating shaft is connected to the second helical gear through a one-way bearing. When the rotating plates swing up and down, the second helical gear can only drive the first helical gear to rotate in a single direction.

[0012] Furthermore, the front side of the filter tank plate extends through to the front of the composite aquaculture tank plate, the rod wall of the power vertical rod extends through to the bottom of the protective shell, and the rod wall of the power vertical rod is rotatably connected to the surface of the protective shell, and the top of the connecting pipe is fixedly connected to the lower end of the power vertical rod. The lower side of the inner wall of the aquaculture tank slopes towards the bottom center and converges at the location of the connecting pipe. The input end of the water pump penetrates the surface of the aquaculture tank and the connecting column and extends into the interior of the connecting column. The output end of the water pump extends to the lower side of the inner wall of the composite aquaculture trough plate. The water pump is used to pump out the sewage in the connecting column.

[0013] Furthermore, the cleaning assembly includes a cleaning inclined tube fixedly installed on one side of the connecting pipe wall, an inclined scraper fixedly installed at the center of the bottom of the cleaning inclined tube, a plurality of first suction ports being provided on both sides of the inclined scraper on the lower side of the inner wall of the cleaning inclined tube, and a plurality of second suction ports being provided on the connecting pipe wall between the cleaning inclined tube and the aquaculture pond.

[0014] Furthermore, a starting spring is fixedly installed on one side of the top of the first helical gear, and a normally open starting switch is fixedly installed at the bottom of the composite aquaculture tank plate along the rotation trajectory of the starting spring.

[0015] Furthermore, the tilt angle of the cleaning inclined tube is the same as the tilt angle of the inner wall of the aquaculture pond. The inclined scraper is a silicone scraper. The interior of the cleaning inclined tube is connected to the interior of the connecting tube. Every time the first helical gear rotates once, it squeezes the normally open start switch once. After the normally open start switch is closed, the water pump is started, which absorbs the fish feces cleaned by rotating once and transports them to the composite aquaculture trough through the connecting tube and the cleaning inclined tube. The wastewater is used to provide nutrients for the plants in the composite aquaculture trough. After the wastewater is absorbed and purified by the plants, it is purified again by the purification component and then flows back to the aquaculture pond to reduce water waste and keep the water quality of the aquaculture pond clean, which is beneficial to aquaculture and reproduction.

[0016] Compared with existing technologies, this invention provides a composite green ecological aquaculture equipment with the following beneficial effects: 1. In this device, the buoyancy block uses the natural undulation of the water surface as the only driving force. By connecting the vertical plate and the rotating plate, it drives the rotating shaft to swing back and forth, realizing energy-saving self-driven cleaning without external power source. The rotating shaft is connected to the second helical gear through a one-way bearing, which converts the reciprocating swing into the one-way intermittent rotation of the first helical gear, ensuring that the cleaning component always rotates in a single direction to scrape fish feces.

[0017] 2. For each rotation of the first helical gear of the device, the spring plate presses the normally open start switch once, triggering the water pump to start, realizing the synchronous linkage between the scraping and agglomeration of fish feces at the bottom of the pool and the adsorption of fish feces, ensuring the accurate timing of the cleaning and suction actions; The cleaning slant pipe rotates with the connecting pipe, and the slant scraper adheres to the inclined surface of the pool bottom to scrape fish feces to the center of the pool bottom. The first and second suction ports simultaneously adsorb fish feces and sewage, cleaning thoroughly without dead corners and preventing long-term accumulation of fish feces from deteriorating water quality.

[0018] 3. The pump in this equipment transports wastewater rich in fish feces to the composite aquaculture tank for plants to absorb and utilize, converting aquaculture waste into plant nutrients, realizing resource utilization, and reducing external pollution. After being absorbed and purified by planted plants, the wastewater enters the purification tank through infiltration vertical holes. It is then finely filtered by filter cotton boards and degraded by nitrifying bacteria in biological filter media. The purified water is then returned to the aquaculture pond through ventilated inclined holes, realizing the recycling of water resources and reducing the frequency of water changes and water costs.

On the left and right sides of the inner wall of the filter plate 501 in the field of fish aquaculture and breeding technology, below the partition mesh plate 502, there are air-permeable inclined holes 503. The air-permeable inclined holes 503 are used to allow the water purified by nitrifying bacteria in the filter plate 501 to overflow.

The upper and lower sides of the inner wall of each vertical infiltration hole 504 are fixedly installed with a barrier net 505. The barrier net 505 is used to prevent the nutrient soil in the composite aquaculture tank plate 2 from entering the purification tank 3.

[0022] In the field of fish aquaculture and breeding technology, a protective shell 6 is rotatably installed on the bottom of the composite aquaculture tank plate 2 around the power vertical rod 4. A first helical gear 8 is fixedly installed on one side of the inner wall of the power vertical rod 4 in the field of fish aquaculture and breeding technology, and three power components 7 are arranged around the first helical gear 8. The power component 7 in the field of fish aquaculture and breeding technology includes a second helical gear 701 that meshes with the surface of the first helical gear 8. The inner wall of the second helical gear 701 in the field of fish aquaculture and breeding technology is connected to a rotating shaft 702 through a one-way bearing. Both ends of the rotating shaft 702 in the field of fish aquaculture and breeding technology are rotatably connected to support blocks 703. In the field of fish aquaculture and breeding technology, the rotating shaft 702 has rotating plates 704 fixedly installed on both sides of the shaft wall opposite to the second helical gear 701. The inner wall of the protective shell 6 in the field of fish aquaculture and breeding technology has an opening 705 on one side of the two rotating plates 704. The lower ends of the two rotating plates 704 in the field of fish aquaculture and breeding technology are rotatably connected to the connecting vertical plates 706, and the bottom of the two connecting vertical plates 706 are fixedly installed with a buoyancy block 707. In the field of fish aquaculture breeding technology, the bottom of the support block 703 is fixedly connected to the lower side of the inner wall of the protective shell 6. One end of the two rotating plates 704 extends to the outside of the protective shell 6 through the movable port 705. The rotating shaft 702 is connected to the second helical gear 701 through a one-way bearing. When the rotating plate 704 swings up and down, the second helical gear 701 can only drive the first helical gear 8 to rotate in a single direction.

[0023] In the field of fish aquaculture and breeding technology, the front side of the filter tank plate 501 extends through to the front of the composite aquaculture tank plate 2, the rod wall of the power vertical rod 4 extends through to the bottom of the protective shell 6, and the rod wall of the power vertical rod 4 is rotatably connected to the surface of the protective shell 6, and the top of the connecting pipe 10 is fixedly connected to the lower end of the power vertical rod 4. In the field of fish aquaculture and breeding technology, the lower side of the inner wall of the aquaculture tank 1 slopes towards the bottom center and converges at the position of the connecting pipe 10. The input end of the water pump 11 in the field of fish aquaculture and breeding technology penetrates through the surface of the aquaculture tank 1 and the connecting column 9 and extends into the interior of the connecting column 9. The output end of the water pump 11 extends to the lower side of the inner wall of the composite aquaculture trough plate 2. The water pump 11 is used to pump out the sewage in the connecting column 9.

[0024] In the field of fish aquaculture and breeding technology, a connecting trough column 9 is embedded in the lower side of the inner wall of the aquaculture pond 1, and a connecting pipe 10 is rotatably installed on the top of the connecting trough column 9. A water pump 11 is fixedly installed on the left side of the top of the composite aquaculture trough plate 2 in the field of fish aquaculture and breeding technology. A cleaning component 12 is provided on the pipe wall of the connecting pipe 10 in the field of fish aquaculture and breeding technology.

[0025] The cleaning component 12 in the field of fish aquaculture and breeding technology includes a cleaning inclined pipe 1201 fixedly installed on one side of the wall of the connecting pipe 10. An inclined scraper 1202 is fixedly installed at the center of the bottom of the cleaning inclined pipe 1201. Several first suction ports 1203 are opened on both sides of the lower inner wall of the cleaning inclined pipe 1201 in the field of fish aquaculture and breeding technology. Several second suction ports 1204 are opened on the wall of the connecting pipe 10 in the field of fish aquaculture and breeding technology between the cleaning inclined pipe 1201 and the breeding pond 1. In the field of fish aquaculture and breeding technology, a starting spring 1205 is fixedly installed on one side of the top of the first helical gear 8, while a normally open starting switch 1206 is fixedly installed at the bottom of the composite aquaculture tank plate 2 along the rotation trajectory of the starting spring 1205. In the field of fish aquaculture and breeding technology, the inclined angle of the cleaning pipe 1201 is the same as the inclined angle of the inner wall of the breeding pond 1. The inclined scraper 1202 is a silicone scraper. The interior of the cleaning pipe 1201 is connected to the interior of the connecting pipe 10. Every time the first helical gear 8 rotates once, it squeezes the normally open start switch 1206 once. After the normally open start switch 1206 is closed, the water pump 11 is started, which absorbs the fish feces cleaned by rotating once and transports them to the composite breeding tank plate 2 through the connecting pipe 10 and the cleaning pipe 1201. The wastewater is used to provide nutrients for the plants in the composite breeding tank plate 2. After the wastewater is absorbed and purified by the plants, it is purified again by the purification component 5 and then returned to the breeding pond 1 to reduce water waste and keep the water quality of the breeding pond 1 clean, which is beneficial to aquaculture and breeding.

[0026] The features that distinguish this device from existing technologies are as follows: The buoyancy block 707 floats up and down with the rise and fall of the water surface, and the buoyancy is converted into the reciprocating swing of the rotating shaft 702 by connecting the vertical plate 706 and the rotating plate 704. The rotating shaft 702 is connected to the second helical gear 701 through a one-way bearing, which converts the reciprocating oscillation into the one-way intermittent rotation of the first helical gear 8, driving the connecting pipe 10 to drive the cleaning assembly 12 to rotate. Each rotation of the first helical gear 8 causes the starting spring 1205 to press the normally open starting switch 1206 once, triggering the water pump 11 to start and complete the synchronous adsorption of fish feces scraped from the bottom of the pond. The inclined tube 1201 rotates with the connecting tube 10, and the inclined scraper 1202 scrapes the fish feces to the center of the bottom of the pond by adhering to the inclined surface of the pond bottom. The first suction port 1203 and the second suction port 1204 simultaneously adsorb the fish feces and sewage, which are then transported to the composite aquaculture trough plate 2 for plant absorption through the connecting tube 10 and the water pump 11. The entire cleaning and pumping cycle is driven by the natural undulation of the water surface, requiring no additional power source or control program, thus achieving energy-saving self-driving pool bottom cleaning.

[0027] The working principle of the above embodiments is as follows: This equipment uses the natural undulations of the water surface in the aquaculture pond 1 as the driving force to drive the cleaning component 12 to periodically clean the fish feces at the bottom of the pond, and transports the wastewater rich in fish feces to the composite aquaculture trough 2 for plants to absorb and utilize. After being purified by the purification component 5, it flows back to the aquaculture pond 1, forming a composite use effect. The water surface in the aquaculture pond 1 fluctuates due to natural wind and waves, the movement of fish, and the oxygenation equipment. The buoyancy block 707 floats up and down with the water surface. The buoyancy block 707 drives the two rotating plates 704 to swing up and down around the second helical gear 701 through two connecting vertical plates 706. The rotating shaft 702 is connected to the second helical gear 701 through a one-way bearing. When the rotating plate 704 swings down, the one-way bearing locks, and the rotating shaft 702 drives the second helical gear 701 to rotate. The second helical gear 701 drives the first helical gear 8 that meshes with it to rotate in a single direction. When the rotating plate 704 swings upward, the one-way bearing is released, the second helical gear 701 spins freely and does not drive the first helical gear 8 to reverse. Through the continuous up and down floating of the buoyancy block 707, the first helical gear 8 achieves intermittent one-way rotation. When the first helical gear 8 rotates, it drives the power vertical rod 4 to rotate. The connecting pipe 10, which is fixedly connected to the lower end of the power vertical rod 4, rotates synchronously. A cleaning inclined pipe 1201 is fixedly installed on one side of the pipe wall of the connecting pipe 10. The inclination angle of the cleaning inclined pipe 1201 is the same as the inclination angle of the inner wall of the aquaculture pond 1. The inclined scraper 1202 (silicone scraper) at the bottom center of the cleaning inclined pipe 1201 fits against the inclined surface of the pond bottom and scrapes the fish feces deposited at the bottom of the pond towards the center of the pond bottom. The starting spring 1205 on one side of the top of the first helical gear 8 rotates with the first helical gear 8. Every time the first helical gear 8 rotates once, the starting spring 1205 presses the normally open starting switch 1206 once. After the normally open starting switch 1206 closes, the water pump 11 is started. Here, when the water pump 11 is pumping water, the first suction port 1203 at the bottom of the cleaning inclined pipe 1201 and the second suction port 1204 on the wall of the connecting pipe 10 absorb the fish feces and sewage that are scraped and collected during the rotation, and flow into the interior of the connecting pipe 10. The input end of the water pump 11 extends into the interior of the connecting trough column 9, and pumps the fish feces and sewage transported by the connecting pipe 10 into the connecting trough column 9. The output end of the water pump 11 extends to the lower side of the inner wall of the composite aquaculture tank plate 2, and transports the sewage rich in fish feces into the composite aquaculture tank plate 2 to provide nutrients for the plants. After the wastewater absorbs some nutrients from the roots of the plants in the composite aquaculture trough 2, it seeps into the purification tank 3 through the seepage vertical holes 504 at the bottom of the composite aquaculture trough 2. The barrier nets 505 on the upper and lower sides of the seepage vertical holes 504 prevent the nutrient soil in the composite aquaculture trough 2 from entering the purification tank 3 to prevent blockage. After the wastewater enters the purification tank 3, it first undergoes fine filtration through the filter cotton plate set on the top of the partition mesh plate 502 to remove suspended particulate matter. Then it enters the biological filter media layer filled at the bottom of the partition mesh plate 502, where nitrifying bacteria convert harmful substances such as ammonia nitrogen in the water into harmless substances such as nitrates, further purifying the water quality. The purified water overflows through the ventilated inclined holes 503 on both sides of the filter plate 501. Since the width of the filter plate 501 is smaller than the width of the purification tank 3, the purified water flows smoothly into the aquaculture pond 1, realizing the recycling of water resources, reducing water waste, and keeping the water quality in the aquaculture pond 1 clean, which is beneficial to aquaculture and reproduction. In this cycle, the buoyancy block 707 continuously drives the cleaning component 12 to rotate with the rise and fall of the water surface. Each rotation cleans the bottom of the pond and starts the water pump 11 once, realizing the regular automatic cleaning of the bottom of the aquaculture pond 1, the resource utilization of sewage, and the continuous purification of water quality.

[0028] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
