Description

Technical Field

[0001] The invention relates to the technical field of aquaculture, in particular to a fry cultivation device used for aquaculture. Background Art

[0002] Fish fry cultivation is the process of cultivating the fry hatched from fish eggs into healthy fish of a certain size after a period of careful feeding and management. In order to optimize the growth environment of fish fry and improve the cultivation efficiency and survival rate, a series of pre-installed or set equipment and technologies are developed and applied. These equipment usually include spawning and hatching equipment, temporary holding and cultivation facilities, water quality management and control systems, aiming to provide a safe, stable and suitable growth condition for fish fry by accurately controlling key factors such as water quality, temperature and light.

[0003] In the process of using breeding equipment to raise fish fry, due to substandard water quality: for example, water temperature, pH value, dissolved oxygen content, ammonia nitrogen indicators do not meet the growth requirements of fish fry or fish fry transported over long distances are directly released without proper treatment, the fish fry will die and sink to the bottom of the breeding equipment. Since there are a large number of fish fry in the breeding equipment and the dead fish fry sink to the bottom, the staff's vision is easily obstructed, making it difficult to find the dead fish fry in time and deal with them. The long-term presence of dead fish fry in the breeding equipment will not only become a breeding ground for pathogens, increasing the risk of disease transmission, but also cause cross-infection, affecting the growth and survival rate of other healthy fish fry. Moreover, after the dead fish fry sink to the bottom, due to the structure of the breeding equipment and the density of the fish fry, the cleaning work will become difficult and time-consuming, which increases the residual time of the dead fish fry in the breeding equipment, causing further deterioration of water quality and affecting the growth of other healthy fish fry.

[0019] (III) Beneficial effects

[0020] Compared with the prior art, the present invention provides a fry cultivation device for aquaculture, which has the following beneficial effects:

[0021] 1. Through the bottom cleaning mechanism set up, the cleaning box can be driven to cooperate with the shovel to move slowly in accordance with the bottom of the incubator, and the dead seedlings and excrement at the bottom of the incubator are cleaned and pushed to the sewage outlet opened on the side wall of the incubator. This not only reduces the residual time of dead seedlings in the incubation equipment, reduces the risk of pathogen breeding, thereby reducing the possibility of disease transmission and cross infection, but also timely cleaning of dead seedlings and excrement helps to keep the water quality in the incubator clean. Clean water quality is essential for the growth of fry, can reduce the occurrence of diseases, improve the survival rate and growth rate of fry, and reduce the labor intensity of staff, shorten the cleaning time, and improve the overall cleaning efficiency of the incubator.

[0022] 2. By interlocking the sealing strips and sealing grooves, the space inside the cleaning box can be isolated from the interior of the incubator when the cleaning box and the shovel push the excrement and dead seedlings inside the incubator to the sewage outlet. This can not only effectively prevent the sewage, excrement or dead seedling remains from flowing back into the incubator during the cleaning process, thereby avoiding secondary pollution of the water quality and improving the water quality of the water source inside the incubator, but also the staff can directly clean the inside of the cleaning box through the sewage outlet without worrying about the pollutants being re-spread into the incubator, making the cleaning work more efficient.

[0023] 3. Through the fry driving mechanism, when the cleaning box moves horizontally to drive the shovel to clean the fry at the bottom of the breeding box, it can drive the driving plate to move up and down slightly above the cleaning box synchronously, which can not only effectively drive the live fry away from the cleaning area, but also enable the cleaning box and the cleaning plate to focus more on cleaning the dead fry, without worrying about accidentally injuring the live fry, reducing the risk of live fry being injured or killed due to accidental contact, and when the density of fry is high, the role of the driving plate is particularly obvious, it can effectively separate the live fry and the dead fry in a limited space, ensuring the smooth progress of the cleaning work, thereby improving the cleaning efficiency.

[0024] 4. By providing the disc, spring, movable column and linkage frame, before the sealing strip is inserted into the sealing groove, it is possible to avoid the situation where live fry remain in the sealing groove and are squeezed by the sealing strip to cause injury or death, thereby ensuring the safety of the fry breeding process. In addition, the remaining fry will affect the smooth insertion of the sealing strip, resulting in a poor sealing effect. By ensuring that there is no fry remaining in the sealing groove, the accurate insertion of the sealing strip can be ensured, thereby improving the sealing performance between the sealing strip and the sealing groove.

[0025] 5. Through the water level detection mechanism, during the cleaning process of the bottom of the incubator, the floating plate can be driven to move synchronously with the surface of the water source inside the incubator to monitor the water level and trigger the alarm when the water level is abnormal. This not only ensures that the staff can understand the water level status in time and find water level abnormalities in time, such as too high or too low water level, so as to take corresponding measures to adjust and avoid affecting the fry in the incubator, but also stimulates the activity of the fry by slowly moving the floating plate against the surface of the water source to prevent the fry from excessively gathering in the incubator, thereby promoting the uniform distribution of the fry in the incubator and optimizing its living environment.

[0040] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] A fish fry cultivation device for aquaculture in this embodiment, such as Figure 1 - Figure 8 As shown, it includes a breeding box 1, and a chute 2 is symmetrically opened on the upper end surface of the breeding box 1. Sewage outlets 6 are opened on both sides of the breeding box 1. It also includes a box bottom cleaning mechanism, a fry driving mechanism and a water level detection mechanism. The box bottom cleaning mechanism includes a movable frame 301, a cleaning box 303 and symmetrically arranged vertical plates 302. The movable frame 301 is slidably connected between the two chute 2. Vertical grooves 309 are opened on the side walls of the vertical plates 302. The box bottom cleaning mechanism is used to clean dead fry and excrement at the bottom of the breeding box 1, and the water level detection mechanism is used to detect the water level in the breeding box 1.

[0042] In this embodiment, Figure 1 - Figure 3 As shown, the vertical plates 302 are fixedly connected to the lower end surface of the movable frame 301, the cleaning box 303 is fixedly connected between the lower ends of the two vertical plates 302, and the cleaning box 303 is attached to the bottom of the incubator 1, and the lower end of the cleaning box 303 is symmetrically fixedly connected with a shovel plate 304, and the inner wall of the cleaning box 303 is provided with a sealing groove 310 near the sewage outlet 6. During the horizontal movement of the movable frame 301, the vertical plates 302 can drive the cleaning box 303 to move synchronously at the bottom of the incubator 1 to collect the dead seedlings and excrement at the bottom of the incubator 1.

[0043] In this embodiment, Figure 3 and Figure 4 As shown, a sealing strip 308 is fixedly connected to one side of the cleaning box 303 close to the sealing groove 310, and the sealing strip 308 and the sealing groove 310 are mutually clamped. By clamping the sealing strip 308 and the sealing groove 310 together, the sealing performance of the internal space of the cleaning box 303 can be improved.

[0044] In this embodiment, Figure 1 As shown, threaded rods 305 are threadedly connected on the movable frame 301, and the threaded rods 305 are rotatably connected to the incubator 1. The threaded rods 305 pass through one end of the incubator 1 and are fixedly connected to a pulley 306. A belt 307 is sleeved between the outer surfaces of the pulleys 306. One of the threaded rods 305 is fixedly connected to the output end of the external drive motor. When the external drive motor is turned on to drive one of the threaded rods 305 to rotate, the other threaded rod 305 can be driven to rotate synchronously through the transmission connection of the sliding column 9 and the belt 307 connected to the outer surfaces of the two threaded rods 305.

[0045] In this embodiment, Figure 8 As shown, the water level detection mechanism includes a fixed plate 501, which is fixedly connected to the center of the upper end surface of the moving frame 301. A through groove 502 is opened on the fixed plate 501, and a lifting plate 503 is slidably connected in the through groove 502. The lower end surface of the lifting plate 503 is symmetrically fixedly connected with connecting columns 504. The connecting columns 504 are all slidably connected to the moving frame 301, and the lower ends of the connecting columns 504 are fixedly connected with floating plates 505. When the floating plate 505 moves up and down with the water level, the lifting plate 503 can be pushed to slide up and down synchronously in the through groove 502 through the arranged connecting columns 504.

[0046] In this embodiment, Figure 8As shown, buttons 506 are symmetrically fixedly connected in the through groove 502, and an alarm 507 is fixedly connected to the upper end surface of the fixed plate 501. The buttons 506 are electrically connected to the alarm 507. When the lifting plate 503 slides up and down in the through groove 502 and touches the buttons 506, the alarm 507 will be turned on to work.

[0047] In the prior art, since there are a large number of fry in the breeding equipment and the dead fry sink to the bottom, the sight of the staff is easily obstructed, and it is difficult to find the dead fry in time and deal with them. The dead fry exist in the breeding equipment for a long time, which will not only become a breeding ground for pathogens, increase the risk of disease transmission, but also cause cross infection, affecting the growth and survival rate of other healthy fry. Moreover, after the dead fry sink to the bottom, it will be difficult and time-consuming to clean up due to the structure of the breeding equipment and the density of the fry, which increases the residual time of the dead fry in the breeding equipment, causing the water quality to deteriorate further, affecting the growth of other healthy fry. Compared with the prior art, the cleaning box 3 can be driven 03 The cooperative shovel plate 304 moves slowly against the bottom of the incubator 1 to clean the dead seedlings and excrement at the bottom of the incubator 1 and push them to the sewage outlet 6 opened on the side wall of the incubator 1. This not only reduces the residual time of the dead seedlings in the incubation equipment and reduces the risk of pathogen breeding, thereby reducing the possibility of disease transmission and cross-infection, but also timely cleaning of the dead seedlings and excrement helps to keep the water quality in the incubator 1 clean. Clean water quality is essential for the growth of fry, can reduce the occurrence of diseases, and improve the survival rate and growth rate of fry. It also reduces the labor intensity of the staff, shortens the cleaning time, and improves the overall cleaning efficiency of the incubator 1.

[0048] In other aspects, this embodiment also provides a fry driving mechanism for driving the fry inside the incubator 1 away from the critical area, such as Figure 1 - Figure 3 , Figure 5 - Figure 7 As shown, the fry driving mechanism includes a driving plate 404, both sides of the driving plate 404 are fixedly connected with lifting blocks 405, the lifting blocks 405 are slidably connected in the vertical groove 309, the upper end surfaces of the lifting blocks 405 are fixedly connected with lifting columns 403, and the lifting columns 403 are slidably connected to the vertical plate 302 and the movable frame 301.

[0049] In this embodiment, Figure 1 and Figure 5As shown, the upper ends of the lifting columns 403 are fixedly connected with connecting plates 406, and the lower end surfaces of the connecting plates 406 are fixedly connected with the side of the lifting columns 403 that are away from the lifting columns 403. The lower ends of the connecting rods 402 are fitted with corrugated plates 401, and the corrugated plates 401 are fixedly connected to the side walls of the incubator 1. The upper end surfaces of the connecting plates 406 are fixedly connected with counterweight blocks 407. When the lifting columns 403 move horizontally and drive the connecting rods 402 to move synchronously through the connecting plates 406, the connecting rods 402 will be affected by the wave crests of the corrugated plates 401 and will rise synchronously during the horizontal movement. When the connecting rods 402 move to the trough of the upper end surface of the corrugated plates 401, they will be affected by the gravity of the counterweight blocks 407 connected to the upper end surface of the connecting plates 406, pushing the connecting plates 406 to drive the connecting rods 402 and the lifting columns 403 to descend.

[0050] In this embodiment, Figure 7 As shown, the fry driving mechanism also includes a linkage frame 408, which is slidably connected to the sealing groove 310, and the linkage frame 408 is symmetrically fixedly connected to the side of the incubator 1 away from the inside of the incubator 1 with a moving column 409, and the moving column 409 is slidably connected to the incubator 1, and the moving column 409 is fixedly connected to the side away from the linkage frame 408 with a disc 410, and a spring 411 is fixedly connected between the disc 410 and the outer wall of the incubator 1, and the spring 411 is sleeved on the moving column 409 On the outer surface, when the linkage frame 408 is subjected to a thrust, it will slide into the sealing groove 310 and push the moving column 409 to slide out of the incubator 1, driving the disc 410 to pull the spring 411 arranged on the outer surface of the moving column 409. When the thrust applied to the linkage frame 408 disappears, the rebound force of the spring 411 can pull the disc 410 close to the incubator 1, push the moving column 409 to slide into the incubator 1, and push the linkage frame 408 out of the sealing groove 310.

[0051] In this embodiment, Figure 6 As shown, baffles 7 are vertically slidably connected in the sewage outlet 6, and sliding columns 9 are rotatably connected to the upper end surfaces of the baffles 7. The sliding columns 9 are all slidably connected to the incubator 1, and knobs 8 are fixedly connected to the upper ends of the sliding columns 9. Threaded grooves 10 are provided on the outer surfaces of the sliding columns 9 near the knobs 8. The sliding columns 9 are threadedly connected to the incubator 1 through the threaded grooves 10. When the knobs 8 are turned to drive the sliding columns 9 to rotate, the threaded grooves 10 provided on the outer surfaces of the sliding columns 9 can enable the sliding columns 9 to slide up and down on the incubator 1, and at the same time, the baffles 7 are pulled to rise and fall in the sewage outlet 6, thereby controlling the opening and closing of the sewage outlet 6.

[0052] In the prior art, when the staff cleans the dead fry inside the breeding equipment, due to the large number of fry in the breeding equipment and the dead fry sinking to the bottom, the live fry will interfere with the staff in the process of cleaning the dead fry. In order to avoid accidentally injuring the live fry, the staff must be cautious, which further reduces the efficiency of cleaning. In the process of cleaning the dead fry, the staff may accidentally touch the live fry, causing the live fry to be injured or killed. Especially when the density of fry is large, the risk of such accidental injury will be higher. Compared with the prior art, when the cleaning box 303 moves horizontally to drive the shovel plate 304 to clean the fry at the bottom of the breeding box 1, the driving plate 404 can be driven to move up and down slightly above the cleaning box 303 synchronously, which can not only effectively drive the live fry away from the cleaning area, but also enable the cleaning box 303 and the cleaning plate to focus more on cleaning the dead fry, without worrying about accidentally injuring the live fry, reducing the risk of live fry being injured or killed due to accidental contact, and when the density of fry is large, the role of the driving plate 404 is particularly obvious, it can effectively separate the live fry and the dead fry in a limited space, ensure the smooth progress of the cleaning work, thereby improving the cleaning efficiency.

[0053] The working process and principle involved in the overall content of the above embodiment are as follows:

[0054] When the staff needs to clean the bottom of the incubator 1, they turn on the external drive motor connected to one of the threaded rods 305 to drive the threaded rod 305 to rotate. Since the two threaded rods 305 are connected to pulleys 306, and belts 307 are sleeved between the outer surfaces of the pulleys 306, when one of the threaded rods 305 rotates, the transmission connection between the pulleys 306 and the belts 307 can drive the other threaded rod 305 to rotate synchronously. As the two threaded rods 305 rotate synchronously, the threaded rods 305 are threadedly connected to the mobile frame 301, so that the mobile frame 301 can be driven to move slowly horizontally in the slide groove 2 symmetrically opened on the upper end face of the incubator 1, and the vertical plate 302 symmetrically connected to the lower end face of the mobile frame 301 can be driven to move synchronously in the incubator 1. At this time, the cleaning box 3 connected to the lower ends of the two vertical plates 302 03, it will move in line with the bottom of the incubator 1 (it should be noted that the interior of the cleaning box 303 is divided into two areas), and the dead seedlings and excrement at the bottom of the incubator 1 are guided into the cleaning box 303 through the shovel plate 304 symmetrically connected to the lower end surface of the cleaning box 303, and the dead seedlings and excrement are pushed to the sewage outlet 6 opened on the side wall of the incubator 1, which not only reduces the residual time of the dead seedlings in the incubation equipment, reduces the risk of pathogen breeding, thereby reducing the possibility of disease transmission and cross infection, and timely cleaning of the dead seedlings and excrement helps to keep the water quality in the incubator 1 clean. Clean water quality is very important for the growth of fry, can reduce the occurrence of diseases, improve the survival rate and growth rate of fry, and reduce the labor intensity of the staff, shorten the cleaning time, and improve the overall cleaning efficiency of the incubator 1;

[0055] When the mobile frame 301 drives the cleaning box 303 to move horizontally to clean the bottom of the incubator 1 through the vertical plate 302, the lifting column 403 connected to the mobile frame 301 will move synchronously with the mobile frame 301. At this time, since the upper end of the lifting column 403 is connected to the connecting plate 406, the lower end of the connecting plate 406 is connected to the linkage rod 402, the lower end of the linkage rod 402 is attached to the upper end surface of the corrugated plate 401, and the upper end of the connecting plate 406 is connected to the counterweight block 407, the lifting column 403 will move with the mobile frame 301. The connecting plate 406 drives the linkage rod 402 to move synchronously with the upper end surface of the corrugated plate 401, and the linkage rod 402 is affected by the peaks of the upper end surface of the corrugated plate 401, and during the movement, it will push the connecting plate 406 to drive the lifting column 403 to slide vertically upward on the moving frame 301. When the linkage rod 402 moves to the valley of the corrugated plate 401, the counterweight block 407 connected to the upper end surface of the connecting plate 406 will be affected by gravity, pushing the connecting plate 406 to move downward, so that the lower end of the linkage rod 402 is always in contact with the upper end surface of the corrugated plate 401. , and at the same time, the lifting column 403 is driven to slide vertically downward on the mobile frame 301, and this is repeated. Through the cooperation between the corrugated plate 401 and the counterweight block 407, the lifting column 403 can be lifted and lowered while following the horizontal movement of the mobile frame 301. Since the lower end of the lifting column 403 is connected to a lifting block 405, the lifting block 405 is slidably connected to the vertical slot 309, and a driving plate 404 is connected between the lifting blocks 405, and the driving plate 404 is arranged above the cleaning box 303, so during the reciprocating movement of the lifting column 403 , the lifting block 405 can drive the driving plate 404 to move up and down slightly above the cleaning box 303 synchronously, which can not only effectively drive the live seedlings away from the cleaning area, but also enable the cleaning box 303 and the cleaning plate to focus more on cleaning the dead seedlings, without worrying about accidentally injuring the live seedlings, thereby reducing the risk of the live seedlings being injured or killed due to accidental contact, and in the case of a large density of fry, the driving plate 404 is particularly effective, and it can effectively separate the live seedlings from the dead seedlings in a limited space, ensuring the smooth progress of the cleaning work, thereby improving the cleaning efficiency;

[0056] When the cleaning box 303 moves horizontally and approaches the sewage outlet 6, the sealing strip 308 connected to the side wall of the cleaning box 303 will move synchronously and be inserted into the sealing groove 310 opened on the side wall of the cultivation box 1, so as to isolate the internal space of the cleaning box 303 from the internal space of the cultivation box 1. This can not only effectively prevent the sewage, excrement or dead seedling debris pollutants from flowing back into the cultivation box 1 during the cleaning process, thereby avoiding secondary pollution of the water quality and improving the water quality of the water source inside the cultivation box 1, but also the staff can directly clean the inside of the cleaning box 303 through the sewage outlet 6 without having to worry about the pollutants being re-dispersed into the cultivation box 1, making the cleaning work more efficient.

[0057] When the sealing strip 308 is inserted into the sealing groove 310, since the sealing groove 310 is slidably connected with the linkage frame 408, the sealing strip 308 will push the linkage frame 408 to slide synchronously in the sealing groove 310, and the moving column 409 symmetrically connected to the side wall of the linkage frame 408 will slide out of the incubator 1 synchronously. At this time, since the moving column 409 is connected to the end away from the linkage frame 408 with a disc 410, and a spring 411 is connected between the disc 410 and the outer wall of the incubator 1, the spring 411 will be pulled synchronously by the disc 410 during the sliding out of the moving column 409, and the sealing strip 308 will be pulled out of the sealing groove 310 in the subsequent When sliding out of the sealing groove 310, the rebound force of the spring 411 will pull the disc 410 close to the incubator 1, and push the movable column 409 to slide into the incubator 1, driving the linkage frame 408 to slide out of the sealing groove 310, not only avoiding the situation where the live fry remain in the sealing groove 310 and are squeezed by the sealing strip 308 to be injured or killed, ensuring the safety of the fry cultivation process, but also the remaining fry will affect the smooth insertion of the sealing strip 308, resulting in poor sealing effect. By ensuring that there is no fry remaining in the sealing groove 310, the accurate insertion of the sealing strip 308 can be ensured, thereby improving the sealing performance between the sealing strip 308 and the sealing groove 310;

[0058] After the sealing strip 308 is completely inserted into the sealing groove 310, the staff can turn the knob 8 to drive the sliding post 9 to rotate synchronously on the upper end surface of the baffle 7. Since the outer surface of the sliding post 9 is provided with a threaded groove 10, and the sliding post 9 is threadedly connected to the incubator 1 through the threaded groove 10, during the rotation of the sliding post 9, it can be synchronously rotated out from the inside of the incubator 1, and the baffle 7 connected to the lower end of the sliding post 9 is pulled to slide upward synchronously inside the sewage outlet 6 to open the sewage outlet 6. At this time, the staff can directly clean the inside of the cleaning box 303 through the sewage outlet 6 without being disturbed by the fry and water source inside the incubator 1.

[0059] When the mobile frame 301 slides horizontally along the slide groove 2 opened on the upper end surface of the incubator 1, it can drive the fixed plate 501 connected to the upper end surface of the mobile frame 301 to move synchronously, and because the mobile frame 301 is symmetrically slidably connected with the connecting column 504, and the lower end of the connecting column 504 is connected with the floating plate 505, when the mobile frame 301 moves horizontally, the floating plate 505 will be driven by the connecting column 504 to move synchronously with the water surface inside the incubator 1. However, when the water level inside the incubator 1 changes, the floating plate 505 will rise and fall with the change of the water level, pulling the connecting column 504 to slide up and down on the mobile frame 301. Since a lifting plate 503 is connected between the upper ends of the connecting columns 504, the lifting plate 503 is vertically slidably connected to the through groove 502 opened on the fixed plate 501, and the through groove 502 is connected to the floating plate 505. Buttons 506 are symmetrically installed above and below, so when the connecting column 504 moves up and down, it can drive the lifting plate 503 to slide up and down synchronously in the through groove 502. If the water level in the incubator 1 changes greatly, the lifting plate 503 will be pulled by the floating plate 505 and the connecting column 504 to press the button 506 in the through groove 502, and the alarm 507 will be turned on to work. This not only ensures that the staff can understand the water level status in time and discover water level abnormalities such as too high or too low water level in time, so as to take corresponding measures to adjust and avoid affecting the fry in the incubator 1, but also the floating plate 505 adheres to the surface of the water source and moves slowly to form ripples, which stimulates the activity of the fry and prevents the fry from excessively gathering in the incubator 1, thereby promoting the uniform distribution of the fry in the incubator 1 and optimizing its living environment.
