Description

Technical Field

[0001] This invention relates to the field of long-snout catfish farming, and more particularly to a green and pollution-free long-snout catfish farming method. Background Technology

[0002] The long-snout catfish has tender, delicious, and nutritious flesh, and its thick swim bladder can be processed into a valuable fish maw. However, wild long-snout catfish are scarce, so in recent years, they have mostly been farmed.

[0003] Because long-snout catfish have high requirements for water quality, extra attention must be paid to the quality of the culture water during aquaculture. Currently, common methods for treating the quality of culture water include directly replacing the culture water or using water purification devices. Directly replacing the culture water wastes a lot of water resources, is time-consuming and labor-intensive, and can easily cause death or injury to the long-snout catfish. Furthermore, current devices used for purifying culture water cannot effectively combine filtering impurities and increasing the oxygen content in the water, resulting in a single purification effect. Therefore, this solution proposes a green and pollution-free long-snout catfish aquaculture method. Summary of the Invention

[0004] The green and pollution-free longsnout catfish farming method proposed in this invention solves the problem of the limited water purification effect in the existing green longsnout catfish farming process.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The green and pollution-free method for farming long-snout catfish includes the following steps:

[0007] S1. Establish a breeding farm and build suitable breeding ponds according to the breeding scale. The bottom and sides of the breeding ponds should be paved with bricks or cement for hardening.

[0008] S2. Establish a water purification system. Install a certain number of water purification devices in the breeding ponds and start them regularly to purify the breeding water in the breeding ponds.

[0009] S3. Disease and pest control: Before releasing fish fry, thoroughly sprinkle quicklime on the bottom layer.

[0010] S4. Regularly inject oxygen into the aquaculture water in the aquaculture pond to increase the oxygen content of the water.

[0011] Water filtration devices for green and pollution-free long-snout catfish farming methods include:

[0012] A filtration mechanism includes a filter plate, a water pump mounted on the filter plate, a fixed pipe rotatably connected to the center of the bottom of the filter plate, and a suction pipe fixed to the bottom of the outer periphery of the fixed pipe. The top surface of the filter plate has a filtration area, the bottom of the filtration area has a water storage area, and a filter screen is installed between the filtration area and the water storage area. The top of the fixed pipe extends above the filter plate and is connected to the water pump inlet through a water inlet pipe. The bottom surface of the filter plate is equipped with a drive assembly for driving the fixed pipe to rotate.

[0013] The water pumping mechanism includes a ring pipe installed on the top surface of the filter plate and multiple water pumping pipes installed on the top surface of the ring pipe. The outlet of the water pump is connected to the ring pipe through the outlet pipe, and the outlets of the multiple water pumping pipes face the filtration area.

[0014] Multiple water spray mechanisms are evenly distributed on the bottom surface of the filter plate. Each water spray mechanism includes an air cylinder fixed to the bottom surface of the filter plate, a piston plate installed inside the air cylinder, and a linkage assembly installed on the bottom surface of the filter plate to drive the piston plate to reciprocate within the air cylinder. One end of the air cylinder is equipped with a water spray pipe and a water pumping pipe connected to the water storage area.

[0015] The above technical solution can not only conveniently purify and remove impurities from the aquaculture water in the aquaculture pond, but also effectively increase the oxygen content in the aquaculture water during the filtration process, while also avoiding the water tank from tangling with the water suction pipe.

[0016] As a further improvement to the above solution, the filtration zone is a circular structure, a scraper is fixed on the outer periphery of the fixed tube, and the other end of the scraper abuts against the inner wall of the filtration zone. A discharge trough is provided on the filter screen along its length, a discharge pipe is fixed at the bottom of the discharge trough, the bottom of the discharge pipe extends to the bottom of the filter plate, and a receiving hopper is detachably installed at the bottom of the discharge pipe.

[0017] The above technical solution utilizes the rotation of the fixed tube to drive the scraper to rotate, thereby scraping the impurities falling on the top surface of the filter screen into the discharge pipe.

[0018] As a further improvement to the above solution, the bottom of the receiving hopper is provided with an opening, and a second filter screen is installed in the opening. A pull ring is installed on the outer wall of the head of the receiving hopper. Limiting plates are fixed on the outer walls of both long sides of the discharge pipe along their length direction. Limiting grooves are opened on the inner walls of both long sides of the receiving hopper along their length direction, and the limiting grooves match the limiting plates. A groove for engaging the discharge pipe is opened at the top of the tail of the receiving hopper.

[0019] Through the above technical solution, the groove makes it easy to slip the receiving hopper onto the discharge pipe, while the limiting groove and limiting plate facilitate the assembly and disassembly of the receiving hopper.

[0020] As a further improvement to the above solution, the linkage assembly includes a fixed shaft rotatably connected to the bottom of the filter plate, a rotating wheel fixed to the bottom of the fixed shaft, a piston rod hinged to the bottom surface of the rotating wheel at a position off-center, and a linkage shaft rotatably connected to the bottom of the filter plate. The other end of the piston rod extends into the air cylinder and is hinged to the outer wall of the piston plate. A driving bevel gear is sleeved on the outer circumference of the fixed tube. A driven bevel gear that meshes with the driving bevel gear is fixed at one end of the linkage shaft. A first linkage bevel gear is sleeved on the outer circumference of the fixed shaft, and a second linkage bevel gear that meshes with the first linkage bevel gear is fixed at the other end of the linkage shaft.

[0021] The above technical solution allows the piston plates in multiple air cylinders to move back and forth along the axial direction of the air cylinders simultaneously by rotating a fixed rotor, thereby drawing water from the water storage area into the air cylinders and then discharging it into the aquaculture pond.

[0022] As a further improvement to the above solution, the drive assembly includes a motor mounted on the bottom of the filter plate and a driven gear sleeved on the outer periphery of the fixed tube, and a driving gear that meshes with the driven gear is fixed at one end of the output shaft of the motor.

[0023] The above technical solution utilizes the rotation of a motor to drive the rotation of a fixed tube.

[0024] As a further improvement to the above solution, the water suction pipe has multiple water inlet holes on its outer periphery that communicate with its interior, and the water suction pipe is arranged perpendicular to the radial direction of the fixed pipe.

[0025] The above technical solution allows for the installation of water suction pipes that facilitate the extraction of aquaculture water from a wider area.

[0026] As a further improvement to the above solution, an auger is installed on the top surface of the water suction pipe along its length, and a transmission component is installed on the outer periphery of the fixed pipe to drive the auger to rotate while the fixed pipe rotates.

[0027] The above technical solution utilizes the rotation of the auger to remove impurities such as aquatic plants that are entangled in the suction pipe.

[0028] As a further improvement to the above solution, the transmission assembly includes a transmission shaft rotatably connected to the outer circumference of the fixed tube and a gear ring sleeved on the outer circumference of the fixed tube. The inner ring of the gear ring is spaced from the outer circumference of the fixed tube. A transmission gear is fixed at the top of the transmission shaft and meshes with the inner ring of the gear ring. A first transmission bevel gear is fixed at the bottom of the transmission shaft. A second transmission bevel gear, which meshes with the first transmission bevel gear, is sleeved on the outer circumference of the auger.

[0029] The above technical solution can be used to drive the transmission shaft to rotate by rotating the fixed tube, and finally achieve the purpose of driving the auger to rotate.

[0030] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0031] 1. Through the coordination of the filtration mechanism, water lifting mechanism, and water spraying mechanism, the aquaculture water can be pumped up by a water pump during the purification process, and then sprayed out through multiple water lifting pipes. The water then falls onto the filter screen, thereby filtering out impurities. The filtered water is then sucked into an air cylinder and sprayed out from the air cylinder back into the aquaculture pond. At the same time, the water lifting pipes increase the time that the water spends in the air, which helps more oxygen dissolve in the water.

[0032] 2. By setting up the auger and transmission components, the auger can be driven to rotate while the fixed pipe is rotating, thereby removing aquatic plants and other debris entangled on the suction pipe. Attached Figure Description

[0041] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0042] Example 1:

[0043] Please combine Figure 1 The water filtration device for the green and pollution-free long-snout catfish farming method of this embodiment includes:

[0044] The filtration mechanism includes a filter plate 1, a water pump 2 mounted on the filter plate 1, a fixed pipe 6 rotatably connected to the bottom center of the filter plate 1, and a suction pipe 17 fixed to the bottom periphery of the fixed pipe 6. Multiple support feet are installed at the bottom corners of the filter plate 1. Multiple water inlet holes communicating with the interior of the suction pipe 17 are opened on the outer periphery. The suction pipe 17 is perpendicular to the radial direction of the fixed pipe 6, and its end does not touch the support feet after rotation. A filtration zone 8 is opened on the top surface of the filter plate 1, and a water storage zone 9 is provided at the bottom of the filtration zone 8. A filter screen is installed between the filtration zone 8 and the water storage zone 9. The top of the fixed pipe 6 extends onto the filter plate 1. The filter plate 1 is connected to the inlet of the water pump 2 via the inlet pipe 7. The inlet pipe 7 is rotatably connected to the fixed pipe 6. The bottom surface of the filter plate 1 is equipped with a drive assembly for driving the fixed pipe 6 to rotate. The drive assembly includes a motor installed at the bottom of the filter plate 1 and a driven gear 27 sleeved on the outer periphery of the fixed pipe 6. One end of the output shaft of the motor is fixed with a drive gear 26 that meshes with the driven gear 27. After the motor rotates, it drives the fixed pipe 6 to rotate, thereby causing the suction pipe 17 to rotate in the aquaculture water. After the water pump 2 is turned on, the aquaculture water is sucked into the fixed pipe 6 through the suction pipe 17, and then enters the inlet pipe 7 from the fixed pipe 6, and finally is discharged through the water pump 2.

[0045] The water lifting mechanism includes a ring pipe 3 installed on the top surface of the filter plate 1 and multiple water lifting pipes 4 installed on the top surface of the ring pipe 3. The outlet of the water pump 2 is connected to the ring pipe 3 through the outlet pipe 10. The outlets of the multiple water lifting pipes 4 face the filtration zone 8. The water discharged by the water pump 12 enters the ring pipe 3 and is then discharged from the ring pipe 3 and sprayed into the filtration zone 8. After being filtered by the filter screen 1, it falls into the water storage zone 9 to wait for discharge.

[0046] The filter zone 8 has a circular structure. A scraper 5 is fixed to the outer periphery of the fixed pipe 6. The other end of the scraper 5 abuts against the inner wall of the filter zone 8. A discharge trough is provided on the first filter screen along its length. A discharge pipe 20 is fixed to the bottom of the discharge trough. The bottom of the discharge pipe 20 extends to the bottom of the filter plate 1. A receiving hopper 22 is detachably installed at the bottom of the discharge pipe 20. The bottom of the receiving hopper 22 has an opening, and a second filter screen is installed in the opening. A pull ring 23 is installed on the outer wall of the head of the receiving hopper 22. Limiting plates 21 are fixed to the outer walls of both long sides of the discharge pipe 20 along its length. Limiting plates 21 are provided to the inner walls of both long sides of the receiving hopper 22 along its length. The limiting groove 24 is set in the direction and matches the limiting plate 21. The top of the tail of the receiving hopper 22 is provided with a groove 29 for locking the discharge pipe 20. When the fixed pipe 6 rotates, it will drive the scraper 5 to rotate. After the scraper 5 rotates, it will scrape the debris falling on the surface of the filter screen into the discharge pipe 20 and then into the receiving hopper 22, thus ensuring that the surface of the filter screen will not accumulate too much impurity. When the impurities in the receiving hopper 22 accumulate to a certain amount, the receiving hopper 22 can be removed from the discharge pipe 20. After cleaning the impurities in the receiving hopper 22, the receiving hopper 22 can be re-locked onto the discharge pipe 20.

[0047] Multiple water spray mechanisms are evenly distributed on the bottom surface of the filter plate 1. Each water spray mechanism includes an air cylinder 15 fixed to the bottom surface of the filter plate 1, a piston plate installed inside the air cylinder 15, and a linkage assembly installed on the bottom surface of the filter plate 1 to drive the piston plate 15 to reciprocate within the air cylinder 15. One end of the air cylinder 15 is equipped with a water spray pipe 16 and a water suction pipe connected to the water storage area 9. Both the water spray pipe 16 and the water suction pipe are equipped with one-way valves. The linkage assembly includes a fixed shaft 13 rotatably connected to the bottom of the filter plate 1, a rotating wheel 14 fixed to the bottom of the fixed shaft 13, a piston rod 28 hinged to the bottom surface of the rotating wheel 14 at an off-center position, and a linkage shaft 19 rotatably connected to the bottom of the filter plate 1. The air cylinder 15 has an opening on the side near the rotating wheel 14, and the other end of the piston rod 28 extends through the opening into the air cylinder 15 and is hinged to the outer wall of the piston plate. A drive bevel gear is sleeved on the outer periphery of the fixed pipe 6. A driven bevel gear that meshes with the drive bevel gear is fixed at one end of the linkage shaft 19. A first linkage bevel gear is sleeved on the outer periphery of the fixed shaft 13. A second linkage bevel gear that meshes with the first linkage bevel gear is fixed at the other end of the linkage shaft 19. When the fixed pipe 6 rotates, it will drive the linkage shaft 19 to rotate. When the linkage shaft 19 rotates, it will drive the fixed shaft 13 to rotate, thereby causing the rotating wheel 14 to start rotating. When the rotating wheel 14 rotates, it can drive the piston plate to move back and forth inside the air cylinder 15 through the piston rod 28. This allows the water in the water storage area 9 to be sucked into the air cylinder 15 through the water pump pipe as the piston plate moves away from the water pump pipe. Then, as the piston plate moves towards the spray pipe 16, the water in the air cylinder 15 is sprayed out from the spray pipe 16 and falls back into the breeding pond.

[0048] The implementation principle of this embodiment is as follows: When purifying aquaculture water, the motor and water pump 2 are started first. After the motor starts, it drives the fixed pipe 6 to rotate, thereby causing the suction pipe 17 to rotate in the aquaculture water. After the water pump 2 is turned on, the aquaculture water is sucked into the fixed pipe 6 through the suction pipe 17, and then enters the inlet pipe 7 from the fixed pipe 6. Finally, it is discharged into the ring pipe 3 through the water pump 2, and then discharged from multiple water lifting pipes 4 and sprayed into the filter area 8. After being filtered by the filter screen 1, it falls into the water storage area 9.

[0049] While the fixed pipe 6 is rotating, it drives multiple water spraying mechanisms to work. When the water spraying mechanism is working, it first sucks the water in the water storage area 9 into the air cylinder 15, and then sprays it out from the water spray pipe 16, and finally falls back into the breeding pond, thus completing the purification and removal of impurities from the breeding water.

[0050] Example 2:

[0051] Combination Figure 1 and Figure 4 This embodiment, based on Embodiment 1, further improves upon the following: An auger 18, arranged along the length of the suction pipe 17, is mounted on the top surface of the suction pipe 17. A transmission assembly is mounted on the outer periphery of the fixed pipe 6 to drive the auger 18 to rotate while the fixed pipe 6 rotates. The transmission assembly includes a transmission shaft 12 rotatably connected to the outer periphery of the fixed pipe 6 and a gear ring 11 sleeved on the outer periphery of the fixed pipe 6. The inner ring of the gear ring 11 is spaced from the outer periphery of the fixed pipe 6. A transmission gear 25 is fixed to the top of the transmission shaft 12, meshing with the inner ring of the gear ring 11. A first transmission bevel gear is fixed to the bottom of the transmission shaft 12. A second transmission bevel gear, meshing with the first transmission bevel gear, is sleeved on the outer periphery of the auger 18.

[0052] The implementation principle of this embodiment is as follows: During the rotation of the fixed pipe 6, the transmission shaft 12 and the auger will rotate around the fixed pipe 6 as the rotation center. Since the gear ring 11 does not rotate with the rotation of the fixed pipe 6, the transmission gear 25 at the top of the transmission shaft 12 will rotate on its own during the rotation with the fixed pipe 6, thereby causing the transmission shaft 12 to rotate on its own. After the transmission shaft 12 rotates, it drives the auger 18 to rotate on its own, thereby removing the water tank and other debris wrapped around the outside of the suction pipe 17 from the suction pipe.

[0053] Example 3:
