Description

Technical Field

[0001] The present invention relates to the field of fish farming, and specifically to an incubation device for the reproduction of black porgy fish. Background Art

[0002] The black porgy fish, also known as black seabream, wuge, sea mullet, etc., is a warm-water bottom fish widely distributed in the coastal waters of China and the East Asian seas. Among them, the artificial incubation of black porgy fish eggs requires strict control of environmental factors such as water quality, temperature, and dissolved oxygen, and attention should be paid to the disinfection of eggs and disease prevention and control.

[0003] Black porgy fish eggs usually need to be incubated in an incubation box or an incubation pond. The fertilized eggs are evenly placed in the incubation equipment. During this period, it is necessary to regularly check and remove unfertilized or dead eggs. After a period of incubation, the fry will hatch out. The dead eggs produced during the incubation of black porgy fish need to be processed in time, otherwise they will pollute the water quality and spread germs, seriously affecting the hatching rate of healthy eggs. Since black porgy fish eggs are floating eggs, healthy eggs will float in the upper and middle layers of the water body of the incubation pond, while dead eggs will gradually sink to the bottom of the pond. Existing incubation devices mostly use a sieve for filtration. Dead eggs will leak out from the mesh holes, and healthy eggs will be retained on the sieve. However, during the sieving process, if the operation force of the staff is too large, the sieve will easily squeeze the healthy eggs, causing the healthy eggs to rupture, with a large operation difficulty, and there will also be a situation of missed sieving.

The resilience of the first spring 19 can be utilized to facilitate the reset movement of the pressing plate 16. Moreover, an adjusting handle 20 slidably extending to the outside of the hatching pond 1 is fixedly installed on the outer side of the pressing plate 16. A long strip groove for limiting the sliding of the adjusting handle 20 is formed on the outside of the hatching pond 1. When the adjusting handle 20 is pulled downward, it can drive the pressing plate 16 to move downward. The pressing plate 16 pushes the mounting block 14 to move through the connecting rod 15. The mounting block 14 can drive the rhombic rod 12 to move horizontally along the inside of the positioning frame 13. The rhombic rod 12 drives the rack plate 11 to contact the gear 10, realizing the flipping of the sealing plate 8, and thus ensuring the discharge of dead eggs without affecting healthy eggs.

Thus, the sealing plate 8 can drive the swing rod 42 to move along the outer side of the arc-shaped sliding frame 43 through the second mounting rod 41 and compress the arc-shaped spring 44. Then, when the sealing plate 8 is reset, the resilience of the arc-shaped spring 44 can be utilized to facilitate the quick reset of the sealing plate 8. Moreover, under the positioning of the arc-shaped sliding frame 43 on the swing rod 42, a limit can be provided for the rotation of the sealing plate 8 to ensure that the sealing plate 8 is in a horizontal state after reset.

[0032] Embodiment 2: Please refer to Figures 1-6, this embodiment further elaborates on Embodiment 1. The water-blocking mechanism in the illustration includes a winding box 22 fixedly installed on the outer side of the hatching pond 1. A sealing strip 23 that cooperates with the winding box 22 is slidably installed on the inner side of the hatching pond 1. The sealing strip 23 is made of metal. A rubber sleeve frame 24 is fixedly installed on the outer side of the inclined plate 21 on the left side of the bottom plate 7. The sealing strip 23 is slidably installed inside the rubber sleeve frame 24. A moving plate 25 is fixedly installed at one end of the sealing strip 23 away from the winding box 22. Two symmetrically distributed screw rods 26 are rotatably installed between the two inclined plates 21. The moving plate 25 is threadedly assembled on the outer side of the screw rod 26. When the two screw rods 26 rotate, they can drive the moving plate 25 to move horizontally along the inner side of the hatching pond 1, realizing the stretching of the sealing strip 23. An installation box 27 is fixedly installed on the outer side of the hatching pond 1. One end of the screw rod 26 extends into the installation box 27. A synchronous belt 28 is rotatably installed between the two screw rods 26. A driving motor 29 is fixedly installed on the outer side of the installation box 27. The output end of the driving motor 29 is fixedly connected to one end of the adjacent screw rod 26. When the driving motor 29 operates, it can drive the corresponding screw rod 26 to rotate, and this screw rod 26 can drive the other screw rod 26 to rotate synchronously through the synchronous belt 28. A triangular protrusion is provided on the top of the pressing plate 16. An elastic push plate 30 is provided on the inclined surface of the triangular protrusion. The elastic push plate 30 is slidably installed inside the adjacent inclined plate 21. When the elastic push plate 30 moves, it can push the pressing plate 16 downward through the triangular protrusion on the top of the pressing plate 16. A resisting plate 31 is fixedly installed on the side of the moving plate 25 away from the sealing strip 23, and the resisting plate 31 and the elastic push plate 30 are on the same horizontal line. When the moving plate 25 moves, it can make the resisting plate 31 contact the elastic push plate 30, and the resisting plate 31 can push the pressing plate 16 downward through the elastic push plate 30, realizing the opening of the sealing plate 8 and enabling the sealing strip 23 to divide the water in the hatching pond 1 into upper and lower layers. Healthy eggs are located above the sealing strip 23, and dead eggs are located below the sealing strip 23, avoiding excessive water discharge when the sealing plate 8 is opened. Both sides of the moving plate 25 are inclined surface structures, and the inclination angle of the inclined surface of the moving plate 25 corresponds to the inclination angles of the two inclined plates 21, facilitating the moving plate 25 to adhere to the outer sides of the inclined plates 21. Two symmetrically distributed rubber blocking strips are fixedly installed on the inner side of the hatching pond 1, and the rubber blocking strips are located above the sealing strip 23, enabling the sealing strip 23 to move along the bottom of the rubber blocking strips, improving the sealing performance between the sealing strip 23 and the rubber blocking strips.

[0033] Embodiment 3: Please refer to Figures 2-8, this embodiment further illustrates other embodiments. The material taking mechanism in the figure includes a pulling frame 35 slidably installed inside the discharging box 6. A filter plate 32 is fixedly installed inside the pulling frame 35, which can filter the water entering the discharging box 6, so that dead eggs and silt impurities stay on the top of the filter plate 32, facilitating the recycling of dead eggs and silt impurities. When the pulling frame 35 is pulled, the dead eggs and silt impurities on the filter plate 32 can be taken out. A drain valve 33 is fixedly installed at the bottom of the discharging box 6, and the filtered water can be discharged outward from the drain valve 33. A baffle 34 is arranged at the bottom of the filter plate 32. A plurality of equally spaced drain holes are formed on the surface of the baffle 34, and the drain holes on the baffle 34 are aligned with the filter holes on the filter plate 32, so that the water passing through the filter plate 32 can be discharged downward from the drain holes of the baffle 34. Two symmetrically distributed abutting rods 36 are fixedly installed on the outer side of the baffle 34. The abutting rods 36 slidably penetrate through the pulling frame 35 and contact the inner side of the discharging box 6. A T-shaped sliding rod 37 is fixedly installed at one end of the baffle 34 away from the abutting rod 36. The T-shaped sliding rod 37 slidably penetrates through the discharging box 6, and a second spring 38 is fixedly installed between one end of the T-shaped sliding rod 37 and the outer side of the discharging box 6. When the pulling frame 35 is inserted into the inner side of the discharging box 6, the abutting rod 36 contacts the inner side of the discharging box 6. Using the reaction force of the discharging box 6 on the abutting rod 36, the abutting rod 36 drives the baffle 34 to move along the bottom of the filter plate 32, and the second spring 38 is stretched through the T-shaped sliding rod 37, so that the drain holes on the baffle 34 are aligned with the filter plate 32. Then, when the pulling frame 35 is taken out from the discharging box 6, the resilience of the second spring 38 can be used to stagger the drain holes on the baffle 34 from the filter holes on the filter plate 32, realizing the sealing of the filter holes of the filter plate 32, which is convenient for the staff to take out dead eggs and silt impurities. A sleeve for limiting the sliding of the T-shaped sliding rod 37 is provided on the outer side of the pulling frame 35, improving the smoothness of the movement of the T-shaped sliding rod 37. A buckle plate 45 is rotatably installed at one end of the pulling frame 35 close to the abutting rod 36. A through hole for limiting the insertion of the buckle plate 45 is provided on the outer side of the discharging box 6. When the pulling frame 35 is inserted into the discharging box 6, the buckle plate 45 can be rotated downward so that the buckle plate 45 abuts against the outer side of the discharging box 6, realizing the locking of the pulling frame 35, which is convenient for installation and disassembly.

[0034] Working principle: First, the staff starts the driving motor 29. The driving motor 29 drives the corresponding screw rod 26 to rotate. This screw rod 26 can drive another screw rod 26 to rotate synchronously through the synchronous belt 28, so that the two screw rods 26 drive the moving plate 25 to move horizontally along the inner side of the hatching pool 1. The moving plate 25 pulls the sealing strip 23 to move along the inner side of the hatching pool 1. When the moving plate 25 contacts the inclined plate 21 on the right side of the bottom plate 7, the abutting plate 31 on the moving plate 25 contacts the elastic push plate 30, causing the abutting plate 31 to push the elastic push plate 30 to move. The elastic push plate 30 moves along the inclined surface of the triangular protrusion on the pressing plate 16. With the cooperation of the support rod 17 and the sleeve plate 18, when the elastic push plate 30 moves horizontally, it can push the pressing plate 16 downward through the triangular protrusion and compress the first spring 19. The pressing plate 16 pushes the mounting block 14 to move through the connecting rod 15, so that the mounting block 14 pushes the rhombic rod 12 to move horizontally along the inner side of the positioning frame 13. The rhombic rod 12 can drive the rack plate 11 to contact the gear 10. The gear 10 drives the corresponding sealing plate 8 to rotate through the first mounting rod 9. At the same time, the sealing plate 8 drives the second mounting rod 41 to rotate synchronously. The second mounting rod 41 drives the swing rod 42 to move along the outer side of the arc-shaped slide 43 and compresses the arc-shaped spring 44. The sealing plate 8 can be in an inclined state, so that the sealing plate 8 opens the drain hole on the bottom plate 7. At the same time, the sealing strip 23 divides the water in the hatching pool 1 into upper and lower layers, so that the healthy eggs are above the sealing strip 23 and the dead eggs are below the sealing strip 23. The water below the sealing strip 23 can be discharged into the discharge box 6. The dead eggs and sludge impurities on the sealing plate 8 enter the discharge box 6 along with the water flow. Then, the falling water flow passes through the filter plate 32 in the pulling frame 35 and enters the bottom of the discharge box 6 and is discharged out through the drain valve 33. The dead eggs and sludge impurities stay on the top of the filter plate 32. At this time, the driving motor 29 drives the corresponding screw rod 26 to rotate in the reverse direction, so that the moving plate 25 moves back to its original position, retracts the sealing strip 23 into the winding box 22, and uses the resilience of the first spring 19 and the arc-shaped spring 44 to make the sealing plate 8 rotate back to its original position. The sealing plate 8 can rotate back and close the drain hole of the bottom plate 7 to seal the hatching pool 1. Finally, the staff opens the water injection pipe 4 to replenish water into the hatching pool 1, rotates the buckle plate 45 to align with the perforation on the discharge box 6, pulls out the pulling frame 35 from the discharge box 6, and uses the resilience of the second spring 38 to make the second spring 38 push the T-shaped sliding rod 37 to move. The T-shaped sliding rod 37 pulls the baffle 34 to move along the bottom of the filter plate 32, so that the drain holes on the baffle 34 are staggered from the filter holes on the filter plate 32 to seal the filter holes of the filter plate 32. The staff can then recycle the dead eggs and sludge impurities on the filter plate 32 to complete the treatment of the dead eggs. During this process, the healthy eggs are not contacted, thus achieving the effect of installing and discharging eggs and improving the convenience of dead egg treatment.
