Description

Technical Field

[0001] This invention belongs to the field of aquaculture technology, and particularly relates to a California bass farming device and farming method. Background Technology

[0002] California bass originally inhabited sandy or muddy bottoms in still or clear, slow-flowing waters with low transparency. Through long-term domestication, they have adapted to slightly more nutrient-rich water environments. This species exhibits significantly better tolerance to low oxygen levels than mandarin fish, surviving in dissolved oxygen levels above 1.5 mg / L. Their suitable temperature range is wide, from 1 to 36.5℃. They begin feeding above 10℃, with 20-30℃ being their optimal growth temperature. They also demonstrate good adaptability to brackish water ponds. Currently, most aquaculture utilizes direct pond culture. Although formulated feeds are widely available, many farmers still feed them frozen fish. Given the California bass's photophobic and heat-sensitive nature, feeding them frozen fish during the hot season can induce them to forage in the middle and lower water layers, helping to maintain a high feeding rate. Water quality control is particularly crucial during this period. However, existing aquaculture facilities still have obvious shortcomings: uneven oxygenation can easily lead to local hypoxia, which restricts growth; feeding relies on manual labor, which is inefficient; and it is difficult to clean the sediment at the bottom of the tank at the same time when changing the water, which affects the aquatic environment and aquaculture results.

[0003] Therefore, it is necessary to design a California bass farming device and farming method to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a California bass farming device and farming method to solve the above-mentioned problems and achieve the goal of improving the farming efficiency and farming effect of California bass.

The opening and closing mechanism is fixedly installed at the bottom of the outer side wall of the breeding box and is used to seal or open the bottom of the breeding box.

[0007] Preferably, the top wall, bottom wall and upper part of the side wall of the breeding box are provided with through holes, the through holes are arranged in an array, and the opening and closing mechanism is used to seal or open the bottom wall of the breeding box.

[0008] Preferably, the opening and closing mechanism includes a sealing plate, one side of which is fixedly connected to the bottom of the outer wall of the breeding box via a hinge. A driving part is fixedly connected to the hinge, and the driving part is rotatably connected to the sealing plate. The driving part is used to drive the sealing plate to close or open to achieve sealing or opening of the bottom wall of the breeding box.

[0009] Preferably, the hinge part includes a connecting plate, which is L-shaped. One end of the connecting plate is fixedly connected to the bottom of the outer wall of the breeding box, and the other end of the connecting plate is rotatably connected to a hinge shaft. Both ends of the hinge shaft are fixedly connected to a support lug, and both support lugs are fixedly connected to the sealing plate.

[0010] Preferably, the driving unit includes a fixing plate, which is horizontally arranged and has one end fixedly connected to the top of the side wall of the connecting plate. An upper hinge seat is fixedly connected to the bottom of the end of the fixing plate away from the connecting plate. The upper hinge seat is rotatably connected to the fixed end of the waterproof telescopic rod, and the telescopic end of the waterproof telescopic rod is rotatably connected to a lower hinge seat. The lower hinge seat is fixedly connected to the sealing plate and located between the two support ears.

[0011] Preferably, the height adjustment mechanism includes a gantry frame, which is fixedly connected to the ground and located above the aquaculture pond. A motor is fixedly connected to one end of the top of the gantry frame, and a lead screw is fixedly connected to one end of the output shaft of the motor. The other end of the lead screw is rotatably connected to the ground. A crossbeam is threadedly connected to one end of the lead screw, and a guide rod is slidably passed through the other end of the crossbeam. The guide rod is vertically arranged and its two ends are fixedly connected to the gantry frame and the ground, respectively. The aquaculture mechanism is fixedly connected to the bottom end of the crossbeam.

[0012] Preferably, the feeding mechanism includes a sliding table, which is slidably mounted on a slide rail, which is fixed to the ground. A feed box is fixedly connected to the top of the sliding table, and a discharge pipe is fixedly connected to the bottom of the side wall of the feed box. The discharge port of the discharge pipe is located above the breeding mechanism.

[0013] Preferably, the oxygen supply and disinfection mechanism includes a fixed platform, which is fixedly connected to the top of another sliding platform. A liquid oxygen tank and an ozone tank are fixedly connected to the top of the fixed platform.

[0014] A method for farming California bass using California bass farming equipment includes the following steps: Release the fish fry into the aquaculture facility and fill the aquaculture pond with aquaculture water; Feed is fed into the aquaculture ponds through a feeding mechanism, ensuring that the feed enters the aquaculture facility. Aquaculture water oxygenation and disinfection: oxygenation and disinfection of the aquaculture water in the aquaculture pond are achieved through an oxygenation and disinfection system. For residue cleaning, after each feeding and aquaculture, at a preset interval, the aquaculture unit is lifted out of the aquaculture water using the height adjustment mechanism. When lifting, the opening and closing mechanism opens, and when the top of the aquaculture unit is above the surface of the aquaculture water, the opening and closing mechanism closes. Then, the height of the aquaculture unit is raised further, and the feed residue in the aquaculture pond is cleaned. After cleaning, the aquaculture unit is lowered back into the aquaculture pond.

[0015] Compared with the prior art, the present invention has the following advantages and technical effects: This invention addresses the problems of uneven oxygenation, low feeding efficiency, and difficult cleaning in existing California bass farming, achieving significant technical benefits through a systematic structural design. First, the oxygen supply and disinfection mechanism combines liquid oxygen heating with ozone synergistically, along with the array-style perforated design of the rearing tanks, effectively solving the problem of uneven oxygen supply in traditional devices. Simultaneously, ozone disinfection reduces the risk of disease. Second, the automated feeding mechanism moves along a sliding rail for precise feeding, replacing manual operation, significantly improving feeding efficiency and reducing feed waste. This aligns with the light- and heat-sensitive habits of California bass, ensuring stable feeding during high-temperature periods. Third, the modular rearing mechanism, through height adjustment and an opening / closing bottom plate design, automatically opens to discharge uneaten feed and feces when the fish are lifted out of the water, achieving simultaneous cleaning of the rearing tanks and the pond bottom, avoiding sedimentation and pollution during water changes. Furthermore, multiple rearing tanks are independently suspended on a gantry frame, facilitating batch management of the fish population. Combined with temperature control adaptability and brackish water compatibility, this significantly optimizes the growth environment, increases stocking density and survival rate, and reduces labor intensity and the risk of water quality deterioration.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Reference Figures 1 to 3 As shown, the present invention provides a California bass farming apparatus, comprising: Aquaculture pond 2 is located on ground level 1; The height adjustment mechanism is fixedly installed at the top of ground 1, and the height adjustment mechanism is located above the breeding pond 2; Multiple breeding units are fixedly installed at the bottom of the adjustment end of the height adjustment mechanism, and the multiple breeding units are equally spaced along the length of the height adjustment mechanism; Multiple opening and closing mechanisms correspond one-to-one with the aquaculture unit. The opening and closing mechanisms are fixedly installed at the bottom of the outer wall of the aquaculture unit. The opening and closing mechanisms are used to seal or open the bottom of the aquaculture unit so that the California bass can be cultured when the bottom of the aquaculture unit is sealed and / or feed residue can be discharged from the aquaculture unit when it is opened. The feeding mechanism is slidably installed on the ground 1. The feeding mechanism is set along the length of the ground 1 and located on one side of the breeding pond 2. The feeding mechanism is used to feed the breeding pond 2. The oxygen supply and disinfection mechanism is slidably installed on the ground 1. The oxygen supply and disinfection mechanism is set along the length of the ground 1 and located on the other side of the breeding pond 2. The oxygen supply and disinfection mechanism is used to supply oxygen and disinfect the breeding pond 2.

[0022] The design is further optimized so that the breeding mechanism includes a connecting rod 18. The top of the connecting rod 18 is fixedly connected to the bottom of the adjustment end of the height adjustment mechanism. The bottom of the connecting rod 18 is fixedly connected to a breeding box 19. The opening and closing mechanism is fixedly installed at the bottom of the outer wall of the breeding box 19. The opening and closing mechanism is used to seal or open the bottom of the breeding box 19.

[0023] To further optimize the design, the top, bottom, and upper parts of the side walls of the breeding box 19 are provided with through holes, arranged in an array. The opening and closing mechanism is used to seal or open the bottom wall of the breeding box 19.

[0024] The through holes on the top wall of the breeding tank 19 ensure that the feed enters the breeding tank 19, while the through holes on the bottom wall ensure that feed residue inside the breeding tank 19 can be discharged through the through holes when the opening and closing mechanism is opened. The through holes on the side wall of the breeding tank 19 are located at the upper part of the side wall. This ensures that when the breeding tank 19 is lifted out of the water surface of the breeding pond 2 and the opening and closing mechanism seals the bottom wall of the breeding tank 19, a certain amount of breeding water can be retained in the breeding tank 19 to ensure the normal survival of the fish fry.

[0025] The design is further optimized so that the opening and closing mechanism includes a sealing plate 20. One side of the sealing plate 20 is fixedly connected to the bottom of the outer wall of the breeding box 19 through a hinge. A driving part is fixedly connected to the hinge. The driving part is rotatably connected to the sealing plate 20. The driving part is used to drive the sealing plate 20 to close or open so as to seal or open the bottom wall of the breeding box 19.

[0026] The design is further optimized. The hinge part includes a connecting plate 21, which is L-shaped. One end of the connecting plate 21 is fixedly connected to the bottom of the outer wall of the breeding box 19. The other end of the connecting plate 21 is rotatably connected to a hinge shaft 27. Both ends of the hinge shaft 27 are fixedly connected to support ears 26, and both support ears 26 are fixedly connected to the sealing plate 20.

[0027] In a further optimized design, the drive unit includes a fixed plate 22, which is horizontally positioned and fixedly connected at one end to the top of the side wall of the connecting plate 21. An upper hinge seat 23 is fixedly connected to the bottom of the end of the fixed plate 22 away from the connecting plate 21. The upper hinge seat 23 is rotatably connected to the fixed end of the waterproof telescopic rod 24. The telescopic end of the waterproof telescopic rod 24 is rotatably connected to a lower hinge seat 25. The lower hinge seat 25 is fixedly connected to the sealing plate 20 and is located between the two lugs 26.

[0028] When the waterproof telescopic rod 24 extends, it drives the sealing plate 20 to rotate around the hinge shaft 27 to a horizontal position. The two sealing plates 20 are joined together to seal the bottom wall of the breeding box 19. At this time, the feed put into the breeding box 19 stays stably in the breeding box 19 for the fish fry to eat. When the waterproof telescopic rod 24 shortens, it drives the sealing plate 20 to rotate in the opposite direction to an inclined position. At this time, the bottom wall of the breeding box 19 is no longer sealed, and feed residue can be discharged from the breeding box 19.

[0029] The scheme is further optimized. The height adjustment mechanism includes a gantry frame 4, which is fixedly connected to the ground 1 and located above the breeding pond 2. A motor 5 is fixedly connected to one end of the top of the gantry frame 4. The output shaft of the motor 5 is fixedly connected to one end of a lead screw 6. The other end of the lead screw 6 is rotatably connected to the ground 1. One end of a crossbeam 8 is threadedly connected to the lead screw 6. A guide rod 7 is slidably passed through the other end of the crossbeam 8. The guide rod 7 is vertically set and its two ends are fixedly connected to the gantry frame 4 and the ground 1 respectively. The breeding mechanism is fixedly connected to the bottom end of the crossbeam 8.

[0030] During the breeding process, the crossbeam 8 is lowered to the lowest position so that the breeding box 19 and the fish fry inside are in the breeding pond 2. After a certain period of breeding, the crossbeam 8 drives the breeding box 19 to a certain height, and then the staff cleans the breeding pond 2. After cleaning, the breeding box 19 is put back into the breeding pond 2.

[0031] The feeding mechanism is further optimized by including a slide table 9, which is slidably mounted on a slide rail 3. The slide rail 3 is fixed to the ground 1. A feed box 16 is fixedly connected to the top of the slide table 9. A discharge pipe 17 is fixedly connected to the bottom of the side wall of the feed box 16. The discharge port of the discharge pipe 17 is located above the breeding mechanism.

[0032] Feed from feed box 16 is thrown onto the top of breeding box 19 through discharge pipe 17, and then enters the breeding box 19 through the through hole in the top wall. When the breeding box 19 needs to be lifted, the discharge pipe 17 is moved between two breeding boxes 19 or between the outermost breeding box 19 and the side wall of the breeding pond 2 through slide rail 3 and slide table 9 to prevent the discharge pipe 17 from obstructing the normal lifting of the breeding box 19.

[0033] The scheme is further optimized. The oxygen supply and disinfection mechanism includes a fixed platform 10, which is fixedly connected to the top of another sliding platform 9. A liquid oxygen tank 11 and an ozone tank 14 are fixedly connected to the top of the fixed platform 10. The outlet of the liquid oxygen tank 11 is fixedly connected to a heater 13. The outlet of the heater 13 is fixedly connected to an oxygen pipe 12. The outlet of the ozone tank 14 is fixedly connected to an ozone pipe 15. Both the oxygen pipe 12 and the ozone pipe 15 are equipped with electrically controlled valves, and the outlets of both are located inside the aquaculture pond 2.

[0034] Oxygen is supplied to the aquaculture pond 2 through oxygen pipe 12, and ozone is released into the aquaculture pond 2 through ozone pipe 15 to achieve sterilization and ensure the normal growth of fish fry.

[0035] A method for farming California bass using California bass farming equipment includes the following steps: Release the fish fry into the aquaculture facility and fill the aquaculture pond 2 with aquaculture water; Feed is fed into the aquaculture pond 2 through a feeding mechanism, ensuring that the feed enters the aquaculture facility. The aquaculture water is oxygenated and disinfected by an oxygen supply and disinfection device. For residue cleaning, after each feeding and aquaculture, at a preset interval, the aquaculture unit is lifted out of the aquaculture water using the height adjustment mechanism. When lifting, the opening and closing mechanism is opened, and the opening and closing mechanism is closed when the top of the aquaculture unit is exposed above the aquaculture water surface. Then, the height of the aquaculture unit is raised again, and the feed residue in the aquaculture pond 2 is cleaned. After cleaning, the aquaculture unit is lowered back into the aquaculture pond 2.

[0036] The working process of this invention is as follows: Before the aquaculture begins, the height adjustment mechanism is used to lower each aquaculture unit to its lowest position. The motor 5 is then started, which drives the lead screw 6 to rotate, causing the crossbeam 8 to move downwards along the guide rod 7 until the aquaculture box 19 is completely submerged in the water of the aquaculture pond 2, providing a suitable living space for the fish fry.

[0037] During the aquaculture process, the feeding mechanism is responsible for feeding at regular intervals. The sliding platform 9 moves along the sliding rail 3, aligning the feed outlet pipe 17 of the feed box 16 directly above the aquaculture tank 19. The feed falls from the feed outlet pipe 17 and enters the tank through the opening in the top wall of the aquaculture tank 19 for the California bass to consume. At the same time, the oxygen supply and disinfection mechanism continues to operate. Liquid oxygen in the liquid oxygen tank 11 is vaporized by the heater 13 and then introduced into the aquaculture pond 2 through the oxygen pipe 12 to replenish the dissolved oxygen in the water; ozone generated by the ozone tank 14 is released into the water through the ozone pipe 15 to kill pathogenic microorganisms and ensure water quality.

[0038] When feed residue needs to be cleaned, the height adjustment mechanism is activated according to the preset cleaning cycle or the monitored residue accumulation. Motor 5 reverses, and the crossbeam 8 raises the aquaculture tank 19 to a certain height above the water surface. Subsequently, the opening and closing mechanism operates: the waterproof telescopic rod 24 shortens, pulling the sealing plate 20 to rotate around the hinge shaft 27, opening the bottom wall of the aquaculture tank 19. Feed residue and some water inside the aquaculture tank 19 are discharged through the bottom wall openings and fall into the aquaculture pond 2 below. After cleaning, the waterproof telescopic rod 24 extends, pushing the sealing plate 20 to a horizontal closed state, resealing the bottom wall of the aquaculture tank 19.

[0039] If a complete cleaning of aquaculture pond 2 is required, all aquaculture tanks 19 can be raised above the water surface first, allowing staff to thoroughly clean the empty pond 2. After cleaning, the aquaculture tanks 19 can be returned to the water using the height adjustment mechanism to restore the aquaculture status.

[0040] Furthermore, when it is necessary to remove the rearing box 19 from the rearing pond 2 for other operations (such as sorting or transfer), the bottom wall of the rearing box 19 can be sealed first through the opening and closing mechanism, and then the crossbeam 8 can be raised. At this time, since the side wall opening is located at the top, a portion of water will be retained inside the rearing box 19 to ensure the survival of the fish fry in the short term. Throughout the process, the feeding mechanism and the oxygen supply and disinfection mechanism can be moved flexibly through the sliding table 9 to avoid interference with the raised and lowered rearing box 19, ensuring smooth and safe operation.

[0041] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0042] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention.
