Description

Technical Field

[0001] This invention relates to the field of fish egg incubation technology, and more particularly to a fish egg incubation device with adjustable water flow speed. Background Technology

[0002] Fish egg hatching is a meticulous process that requires monitoring and adjustment in many aspects, among which water flow speed is a very important factor.

[0003] Existing devices typically use water pumps to circulate water within the hatching tank during fish egg incubation. This helps keep the surface of the eggs clean, ensures sufficient oxygen supply, and washes away deposits and bacteria to prevent rotting and infection. However, existing devices struggle to adjust the water flow rate during incubation, maintaining a constant flow that is difficult to adapt to different stages of incubation. This reduces operational convenience and increases the difficulty of operation.

[0004] Therefore, in order to address the above problems, a fish egg hatching device that can recycle water resources and adjust the water flow rate is now being developed. Summary of the Invention

[0005] To overcome the shortcomings of existing devices that are difficult to adjust the water flow speed during the incubation process, where the water flow is always at the same speed and cannot adapt to different stages of fish egg incubation, resulting in reduced ease of operation and increased operational difficulty, this invention provides a fish egg incubation device that can recycle water resources and adjust the water flow speed.

[0006] The technical solution of the present invention is: a fish egg hatching device with adjustable water flow speed, comprising a base, a water tank, an adjustment mechanism, and a purifier. The water tank is connected to the top of the base, and water inlets are opened on both the front and rear sides of the water tank. The adjustment mechanism is provided on the water tank, and the adjustment mechanism includes an adjustment cover, an adjustment fan blade, a dual-axis motor, a circulation pipe, and a water pump. The adjustment cover is bolted to both the front and rear sides of the water tank, and the adjustment fan blade is rotatably connected inside the adjustment cover. The dual-axis motor is bolted to the left side of both the front and rear sides of the water tank, and the right output shaft of the dual-axis motor is connected to the adjustment fan blade. The water pump is bolted to the middle right side of the water tank, and a circulation pipe is connected between the water pump and the adjustment cover. The purifier is connected to the circulation pipe on the rear side.

[0007] Optionally, it also includes an egg-holding mechanism, which includes a base, an incubation frame, a placement plate, a first spring, and a fixing block. Three bases are bolted to the bottom of the water tank, and an incubation frame is placed on top of each base. Four first springs are connected to the bottom of each incubation frame, and a placement plate is connected between the tops of adjacent first springs. Fixing blocks are connected to the left and right sides of the incubation frame.

[0008] Optionally, the system also includes a filtration mechanism, which comprises a limiting frame, a fixed filter frame, a sliding filter frame, a locking block, a second spring, a slide rod, a guide seat, a rotating disk, a telescopic rod, a third spring, a fixing component, and a transmission assembly. Limiting frames are connected to both the front and rear sides of the water tank. A fixed filter frame is connected to the side of the limiting frame closest to the inlet. Two sliding filter frames are slidably connected to each limiting frame. A locking block for engaging with the limiting frame is slidably connected to the left side of each sliding filter frame. A second spring connects the locking block to the adjacent sliding filter frame. Guide seats are bolted to the upper left side of both the front and rear parts of the water tank. Two slide rods for pushing adjacent locking blocks are slidably connected to the guide seats. Fixing components are bolted to both the front and rear sides of the left side of the water tank. A rotating disk is rotatably connected to each fixing component. A telescopic rod for pushing adjacent slide rods is slidably connected inside each rotating disk. A third spring connects the telescopic rod to the adjacent rotating disk. A transmission assembly connects the left output shaft of the dual-shaft motor to the adjacent rotating disk.

[0009] Optionally, it also includes a lifting mechanism, which includes a cylinder, a connecting frame, a connecting rod, a guide rod, and a fixed frame. The cylinder is bolted to the left side of the water tank, and the connecting frame is connected to the cylinder's telescopic rod. Three connecting rods that are respectively connected to the fixed blocks on the left side are connected to the right side of the connecting frame. The fixed frame is bolted to the upper right side of the water tank, and three guide rods that are slidably connected to the fixed blocks on the right side are connected to the left side of the fixed frame.

[0010] Optionally, it also includes a monitoring mechanism, which includes cameras and displays. The left side of the water tank is bolted with symmetrically arranged front and rear cameras, and the left side of the water tank is bolted with symmetrically arranged front and rear displays.

[0011] Optionally, it also includes a testing mechanism, which includes a limit frame, a testing instrument, and a probe. The limit frame is bolted to the right side of the water tank near the front. The testing instrument is slidably connected to the limit frame, and a probe is connected to the bottom of the testing instrument.

[0012] Optionally, the transmission assembly includes a transmission wheel and a transmission belt. The left output shaft of the dual-axis motor and the rotating disk are both connected to transmission wheels, and a transmission belt is wound between adjacent transmission wheels.

[0013] Optionally, the detector and the limit frame have a detachable connection structure.

[0014] The beneficial effects of this invention are: 1. This invention uses a water pump to draw water from the water tank, causing the water to circulate in the circulation pipe, thereby increasing the oxygen content in the water. At the same time, the water flow rate is controlled by a dual-axis motor to prevent fish eggs from rotting and becoming infected, thus improving the success rate of fish egg hatching.

[0015] 2. This invention places fish egg frames on a placement plate, allowing fish eggs to be hatched in batches within different hatching frames, thus avoiding mutual interference between fish eggs and improving hatching efficiency.

[0016] 3. As the output shaft of the dual-axis motor adjusts its rotation speed, the rotating disk will extend the telescopic rod, thereby pushing and squeezing the adjacent sliding rod. This will cause the locking block to no longer engage with the limiting frame, and the sliding filter frame will slide downwards due to its own gravity. This will enhance the filtration effect of the fixed filter frame on the water flow and prevent the water flow rate from being too fast, making it difficult for the fixed filter frame to effectively filter impurities.

[0017] 4. This invention controls the connecting frame to move by means of a cylinder telescopic rod, thereby causing the left fixed block to move the incubation frame, and causing the right fixed block to slide upward along the guide rod, thereby quickly removing the fish egg frame placed in the incubation frame.

Detailed Implementation

[0029] The embodiments of the present invention will be described below with reference to the accompanying drawings.

[0030] A fish egg incubation device with adjustable water flow rate, such as Figure 1 and Figure 2 As shown, it includes a base 1, a water tank 2 and an adjustment mechanism 4. The top of the base 1 is connected to the water tank 2 for storing water. The water tank 2 has water inlets 3 on both the front and rear sides for injecting water. The water tank 2 is equipped with an adjustment mechanism 4 for adjusting the water flow rate.

[0031] It should be noted that this device can be used to place fish eggs during incubation. First, sufficient water is introduced into water tank 2, and then the fish eggs are placed in water tank 2 for incubation. During the incubation process, the adjustment mechanism 4 is activated to regulate the water flow rate in water tank 2, thereby making the water in water tank 2 circulate and preventing the water in water tank 2 from becoming stagnant, which would reduce the oxygen content in the water and be detrimental to the hatching of fish eggs, thus improving the hatching success rate.

[0032] like Figure 1 and Figure 3 As shown, the adjustment mechanism 4 includes an adjustment cover 41, an adjustment fan blade 42, a dual-axis motor 43, a circulation pipe 44, a water pump 45, and a purifier 46. The front and rear sides of the water tank 2 are bolted to the adjustment cover 41 for sealing the water inlet 3. The adjustment fan blade 42 for changing the water flow speed is rotatably connected inside the adjustment cover 41. The front and rear sides of the water tank 2 are bolted to the left side of the dual-axis motor 43. The output shaft of the dual-axis motor 43 is set to the left and right. The right output shaft of the dual-axis motor 43 is connected to the adjustment fan blade 42. The right middle position of the water tank 2 is bolted to the water pump 45. The water pump 45 and the adjustment cover 41 are connected to the circulation pipe 44 for promoting water circulation. The circulation pipe 44 on the rear side is connected to the purifier 46 for purifying the circulating water.

[0033] It should be noted that during fish egg incubation, in order to ensure sufficient oxygen content in the water in tank 2 and keep the surface of the fish eggs clean, the water needs to flow at a certain speed. At this time, the water pump 45 can be started to circulate the water in tank 2 within the circulation pipe 44. During the water circulation process, the water is purified by the purifier 46 to ensure water quality. At the same time, the dual-shaft motor 43 is started, causing the output shaft of the dual-shaft motor 43 to drive the regulating fan blades 42 to rotate. This allows for rapid adjustment of the water flow speed at different stages of fish egg incubation, washing away deposits and bacteria attached to the surface of the fish eggs, preventing fish egg rot and infection, and improving the success rate of fish egg hatching. In summary, by using the water pump 45 to draw water from tank 2 and circulate the water within the circulation pipe 44, the oxygen content in the water is increased. At the same time, the dual-shaft motor 43 controls the water flow speed to prevent fish egg rot and infection, thereby improving the success rate of fish egg hatching.

[0034] like Figure 1 and Figure 4 As shown, it also includes an egg-holding mechanism 5, which includes a base 51, an incubation frame 52, a placement plate 53, a first spring 54, and a fixing block 55. Three bases 51 are bolted to the bottom of the water tank 2. An incubation frame 52 for supporting the fish egg frame is placed on the top of each base 51. Four first springs 54 are connected to the bottom of each incubation frame 52. A placement plate 53 is connected between the tops of adjacent first springs 54. Fixing blocks 55 are connected to the left and right sides of the incubation frame 52 to facilitate lifting and picking up.

[0035] It should be noted that, in order to hatch fish eggs in batches and avoid mutual interference, the fish egg frames can be placed on the placement plate 53. The first spring 54 provides cushioning support for the fish egg frames to prevent the fish eggs at the bottom from being crushed or damaged. When the fish eggs have successfully hatched and the fish egg frames need to be removed, the hatching frames 52 can be detached from the base 51 simply by lifting the fixing block 55. In summary, by placing the fish egg frames on the placement plate 53, the fish eggs can be hatched in batches in different hatching frames 52, avoiding mutual interference between the fish eggs and improving the hatching efficiency.

[0036] like Figure 1 , Figure 5 , Figure 6 and Figure 7As shown, it also includes a filtration mechanism 6, which includes a limiting frame 61, a fixed filter frame 62, a sliding filter frame 63, a locking block 64, a second spring 65, a slide rod 66, a guide seat 67, a rotating disk 68, a telescopic rod 69, a third spring 610, a fixing member 611, and a transmission assembly 612. Limiting frames 61 are connected to both the front and rear sides of the water tank 2. A fixed filter frame 62 for filtering the flowing water is connected to the side of the limiting frame 61 near the inlet 3. Two sliding filter frames 63 for enhancing the filtration effect are slidably connected to the limiting frame 61. A locking block 64 for engaging with the limiting frame 61 is slidably connected to the left side of each sliding filter frame 63. A second spring 65 is connected between each locking block 64 and the adjacent sliding filter frame 63, and the second spring 65 is wound around the adjacent locking block 64. The front and rear parts of the water tank 2... The upper left side is bolted to guide seats 67, and two sliding rods 66 for pushing adjacent locking blocks 64 are slidably connected to guide seats 67. The front and rear left sides of water tank 2 are bolted to fixing parts 611, and rotating disks 68 are rotatably connected to fixing parts 611. Telescopic rods 69 for pushing adjacent sliding rods 66 are slidably connected inside rotating disks 68. A third spring 610 is connected between telescopic rods 69 and adjacent rotating disks 68. The third springs 610 are wound around adjacent telescopic rods 69. The left output shaft of dual-axis motor 43 is connected to adjacent rotating disks 68 with transmission components 612. Transmission components 612 include transmission wheels and transmission belts. Transmission wheels are connected to the left output shaft of dual-axis motor 43 and rotating disks 68. Transmission belts are wound between adjacent upper and lower transmission wheels.

[0037] It should be noted that as the operator adjusts the water flow speed using the dual-axis motor 43, the left output shaft of the dual-axis motor 43 will rotate at the same speed. When the output shaft of the dual-axis motor 43 is rotating rapidly, it will drive the transmission component 612 to make the rotating disk 68 rotate synchronously. Under the action of centrifugal force, the telescopic rod 69 extends and is thrown out. The third spring 610 is stretched. After the telescopic rod 69 extends, as the rotating disk 68 rotates, the telescopic rod 69 will push the adjacent sliding rod 66. At this time, the telescopic rod 69 will push the sliding rod according to the extension length. When the dual-axis motor 43 is at its fastest speed, the telescopic rod 69 extends to its longest length, thus pushing both sliding rods 66 simultaneously. At a slower speed, only the closest sliding rod 66 is pushed, causing both sliding rods 66 to slide to the right along the guide seat 67, pushing the locking block 64. This causes the locking block 64 to slide to the right, compressing the second spring 65. As the locking block 64 slides to the right, it no longer engages with the adjacent limiting frame 61. Under the influence of gravity, the sliding filter frame 63 slides downwards along the limiting frame 61, preventing the water flow from being too fast. The filtration effect of the fixed filter frame 62 is reduced, thereby enhancing the filtration effect on the water flow. This ensures that the water entering the water tank 2 undergoes multiple filtrations, preventing debris in the water flow from affecting the hatching of fish eggs. After the fish eggs have hatched, the dual-shaft motor 43 is turned off. At this time, the rotating disk 68 is no longer driven by the transmission component 612 and stops rotating. Under the action of the third spring 610, the telescopic rods 69 will retract and reset. Finally, the sliding filter frame 63 is pulled upward along the limiting frame 61 and reset, so that the locking block 64 is no longer squeezed by the limiting frame 61. Then, in the second spring... Under the action of spring 65, it slides to the left to reset, thus engaging with the limiting frame 61 again, completing the limiting lock of the sliding filter frame 63. In summary, as the output shaft of the dual-axis motor 43 adjusts its rotation speed, the rotating disk 68 will throw out the telescopic rod 69 to extend, thereby pushing and squeezing the adjacent sliding rod 66. As a result, the locking block 64 will no longer engage with the limiting frame 61, and the sliding filter frame 63 will slide downward due to its own gravity, thereby enhancing the filtration effect of the fixed filter frame 62 on the water flow and preventing the water flow rate from being too fast, making it difficult for the fixed filter frame 62 to effectively filter impurities.

[0038] like Figure 1 and Figure 8 As shown, it also includes a lifting mechanism 7, which includes a cylinder 71, a connecting frame 72, a connecting rod 73, a guide rod 74, and a fixing frame 75. The cylinder 71 is bolted to the left side of the water tank 2. The connecting frame 72 is connected to the telescopic rod 69 of the cylinder 71. Three connecting rods 73, which are respectively connected to the fixing block 55 on the left side, are connected to the right side of the connecting frame 72. The fixing frame 75 is bolted to the upper right side of the water tank 2. Three guide rods 74, which are slidably connected to the fixing block 55 on the right side, are connected to the left side of the fixing frame 75.

[0039] It should be noted that after the fish eggs have hatched, the cylinder 71 is activated, causing the cylinder 71 extension rod 69 to extend upward, which in turn drives the connecting frame 72 to move the connecting rod 73 upward. This causes the left-side fixing block 55 to move the adjacent hatching frame 52 upward, and the right-side fixing block 55 to slide upward along the adjacent guide rod 74, making it easy for the operator to quickly retrieve the eggs. In summary, by controlling the connecting frame 72 to move the connecting rod 73 through the extension rod 69 of the cylinder 71, the left-side fixing block 55 moves the hatching frame 52, and the right-side fixing block 55 slides upward along the guide rod 74, thereby quickly removing the fish egg frame placed in the hatching frame 52.

[0040] like Figure 1 and Figure 9 As shown, it also includes a monitoring mechanism 8, which includes a camera 81 and a display screen 82. The left side of the water tank 2 is connected by bolts to a symmetrically arranged camera 81 for monitoring the hatching of fish eggs. The left side of the water tank 2 is connected by bolts to a symmetrically arranged display screen 82 for displaying the monitoring images.

[0041] It should be noted that during the fish egg incubation process, the incubation status is monitored by camera 81, allowing for real-time observation of the incubation process. This enables rapid handling of any abnormalities and facilitates the detection of broken or rotten fish eggs by operators.

[0042] like Figure 1 and Figure 10 As shown, it also includes a detection mechanism 9, which includes a limit frame 91, a detector 92 and a probe 93. The limit frame 91 is bolted to the right side of the water tank 2 near the front. The detector 92 for testing water quality is slidably connected to the limit frame 91. The detector 92 and the limit frame 91 are detachably connected. The probe 93 is connected to the bottom of the detector 92.

[0043] It should be noted that during the incubation of fish eggs, the water quality in tank 2 needs to be monitored in real time to avoid the water quality being too poor and affecting the hatching of the fish eggs. The water quality is monitored by probe 93 contacting the water source, and the test results are provided by the detector 92, which will prompt the operator whether the water in tank 2 needs to be replaced.

[0044] The above embodiments are provided for those skilled in the art to implement or use the present invention. Those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope that conforms to the innovative features mentioned in the claims.
