Description

Technical Field

[0001] This invention relates to the field of zebrafish farming technology, and more particularly to a zebrafish farming tank. Background Technology

[0002] Zebrafish have elongated, slightly spindle-shaped bodies, small, slightly pointed heads, and short snouts. Their bodies are covered with multiple dark blue longitudinal stripes resembling zebra stripes, interspersed with silver-white or golden-yellow longitudinal stripes in a relatively orderly pattern. During the breeding process, it is necessary to change the water in the breeding tank regularly to prevent harmful substances accumulated in the water from harming the zebrafish.

[0003] Current methods for changing the water mainly involve fishermen using nets to scoop out zebrafish from the rearing tank, draining the water, pouring in fresh water, and then putting the scooped-out zebrafish back in. While this method does change the water, it is time-consuming and labor-intensive, and fishermen are very likely to injure the zebrafish while scooping them out. Therefore, we propose a zebrafish rearing tank. Summary of the Invention

[0004] To address the technical problem of inconvenient water changes in existing zebrafish rearing tanks, this invention provides a zebrafish rearing tank.

[0005] This invention is achieved using the following technical solution: a zebrafish breeding tank, comprising a tank body, wherein the tank body has a breeding chamber and a drainage chamber, a loading box is slidably connected inside the breeding chamber, a sealing box is provided on the top of the tank body, the sealing box has a feeding chamber and a storage chamber, a feeding component is provided in the feeding chamber, a winding column is provided inside the storage chamber, a winding rope is fixedly wound around the outer walls at both ends of the winding column, and the end of the winding rope away from the winding column is fixed to the loading box, an installation groove is provided on the inner wall between the breeding chamber and the drainage chamber, a filter screen is fixed inside the installation groove, a drainage pipe communicating with the drainage chamber is installed at the bottom of the tank body, and a butterfly valve is installed on the drainage pipe. Through the coordinated operation of the above components, zebrafish can be bred, and the breeder can change the breeding water.

[0006] As a further improvement to the above solution, the bottom of the loading box is fixed with multiple support feet, and each support foot is fitted with a threaded sleeve. The internal thread of the threaded sleeve is threaded through a screw rod that is rotatably connected to the inner wall of the bottom of the breeding chamber. The inside of the drainage chamber is rotatably connected to a rotating rod. A transmission wheel is fixedly sleeved on the outer wall of the screw rod and the outer wall of the rotating rod near the rotating rod. A transmission belt is externally connected to the transmission wheel. Multiple cams that work with the filter screen are fixedly sleeved on the outer wall of the rotating rod. Through the coordinated operation of the above components, the zebrafish can be blocked during the water discharge process. The blocking component can be vibrated and cleared, improving the endurance of the blocking component.

[0007] As a further improvement to the above solution, a drive column is fixed to the bottom of one end of the sealing box. The end of the drive column away from the sealing box is rotatably connected to a loading shell fixed on the box body. A motor is fixed inside the loading shell. A transmission column is driven to the output end of the motor. The end of the transmission column away from the motor extends to the outside of the loading shell and is fixedly sleeved with a drive gear. A driven gear that meshes with the drive gear is fixedly sleeved on the outer wall of the drive column. A support leg is hinged to the outside of the sealing box. A sliding groove is opened at the bottom of the support leg. A slider is slidably connected inside the sliding groove. A bolt is threaded to the bottom of the support leg. Multiple threaded grooves are opened on the side of the slider near the bolt. The bolt is threadedly connected inside the adjacent threaded grooves. Through the coordinated operation of the above components, the breeder can make adaptive adjustments to the breeding box.

[0008] As a further improvement to the above solution, the bottom of the sealing box is provided with an opening that communicates with the storage cavity. The loading box works in a sliding fit with the opening, and the loading box can be flexibly moved through the opening.

[0009] As a further improvement to the above solution, the feeding assembly includes a feeding cylinder that slides inside the feeding chamber. A discharge port, which slides and engages with the feeding cylinder, is located at the bottom of one end of the feeding chamber. A flat block is fixed to the inner wall of the top of the feeding chamber above the discharge port. Discharge plates, fixed to the inner wall of the feeding chamber, are located on both sides of the feeding cylinder. A transmission block is fixed to the outer side of the feeding cylinder. A threaded sleeve is embedded in the transmission block. A worm gear passes through the inside of the threaded sleeve. The outer wall of the worm gear has an external thread that engages with the internal thread of the threaded sleeve. A slidable connection is made to the end of the feeding chamber furthest from the feeding cylinder. The push plate has a connecting shaft rotatably connected to the inside of the feeding chamber on the side away from the feeding cylinder. A cam that works with the push plate is fixedly sleeved on the outer wall of the connecting shaft. A worm wheel that meshes with a worm gear is also fixedly sleeved on the outer wall of the connecting shaft. A sliding groove is opened on the inner wall of the top of the feeding chamber. A sliding block fixed on the push plate is slidably connected inside the sliding groove. Multiple push springs with their other ends fixed on the sliding blocks are fixed on the inner wall of the sliding groove. Through the operation of the feeding assembly, fish food can be periodically fed to the zebrafish being raised. The amount of fish food can be precisely controlled according to the number of zebrafish in the breeding tank.

[0010] As a further improvement to the above solution, a second motor is fixed to the inner wall of one end of the feeding chamber. One end of the worm gear is connected to the output end of the second motor gear, and the other end of the worm gear is rotatably connected to the inner wall of the feeding chamber. The push plate has a rotating hole, and the worm gear rotates inside the rotating hole. By running the second motor gear, the worm gear can be driven to rotate. Through the rotating hole, the worm gear can rotate flexibly.

[0011] As a further improvement to the above solution, the bottom of the loading box is provided with a support frame fixed to the inner wall of the breeding chamber, and a sliding opening is provided on the inner wall between the breeding chamber and the drainage chamber. The transmission belt slides inside the sliding opening. The loading box can be supported by the support frame, and the transmission belt can slide flexibly by the sliding opening.

[0012] As a further improvement to the above solution, a feeding valve connected to the feeding chamber is installed on the top of the sealing box. The feeding valve is located between the feeding cylinder and the push plate. Through the feeding valve, a sufficient amount of fish food can be injected into the feeding chamber.

[0013] As a further improvement to the above solution, the flattening block has an L-shaped structure, and the bottom of the flattening block slides in conjunction with the top of the feeding cylinder. Through the flattening block, the fish food accumulated on the top of the feeding cylinder can be scraped off, thereby effectively increasing the amount of fish food inside the feeding cylinder and improving the feeding accuracy.

[0014] As a further improvement to the above solution, a motor is fixed to the inner wall of one end of the storage cavity, one end of the winding column is driven to the output end of the motor, and the other end of the winding column is rotatably connected to the inner wall of the storage cavity. The winding rope slides inside the opening, and the winding column can be driven to rotate by the operation of the motor.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. This invention can be used to raise zebrafish and allows for easy and convenient water exchange, avoiding the need for repeated catching of zebrafish by the breeder. It is convenient to use and allows for regular feeding of the zebrafish, saving manpower.

[0017] 2. This invention allows for adaptive adjustment of the breeding tank according to the user's needs, and can precisely control the amount of fish food based on the number of zebrafish inside the breeding tank. It can also periodically unclog the drainage components of the breeding tank, thereby effectively improving the endurance of the drainage components and achieving high performance.

[0030] 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.

[0031] Example 1:

[0032] Combination Figure 1 This embodiment of a zebrafish breeding box includes a box body 1, which has a breeding chamber 2 and a drainage chamber 3. A loading box 4 is slidably connected inside the breeding chamber 2. A sealing box 5 is provided on the top of the box body 1. The sealing box 5 has a feeding chamber 6 and a storage chamber 7. A feeding component is provided in the feeding chamber 6. A winding column 8 is provided inside the storage chamber 7. A winding rope 9 is fixedly wound around the outer walls of both ends of the winding column 8. The end of the winding rope 9 away from the winding column 8 is fixed to the loading box 4. An installation groove is provided on the inner wall between the breeding chamber 2 and the drainage chamber 3. A filter screen 10 is fixed inside the installation groove. The filter screen 10 is made of flexible material. A drain pipe 11 communicating with the drainage chamber 3 is installed at the bottom of the box body 1. A butterfly valve is installed on the drain pipe 11.

[0033] The implementation principle of a zebrafish breeding tank in this embodiment is as follows: When zebrafish need to be bred, sufficient water can be injected into the tank 1. After the water injection is completed, the zebrafish can be placed into the breeding chamber 2 for feeding. After the zebrafish in the tank 1 have been fed for a period of time, when it is necessary to change the water in the tank 1, the butterfly valve can be opened. At this time, the water in the breeding chamber 2 and the drain chamber 3 can be discharged through the drain pipe 11. Through the filter screen 10, the zebrafish in the breeding chamber 2 will be blocked from entering the loading box 4 as the water flows out, thus preventing the zebrafish from entering the drain pipe 11 and being affected by the drain pipe 11. After the water in the tank 1 is drained, the zebrafish can be carried in the loading box 4. After the water in the tank 1 is drained, the winding rope 9 can be wound up by rotating the winding column 8. At this time, the winding rope 9 will pull the loading box 4 to move vertically upward. After the loading box 4 enters the storage chamber 7, the breeder can inject new water into the tank 1. After the new water is injected, the winding rope 9 can be released by rotating the winding column 8. At this time, the loading box 4 will move vertically downward. After the loading box 4 enters the breeding chamber 2, the zebrafish inside the loading box 4 will swim out of the loading box 4 and enter the breeding chamber 2. At this time, the breeder can continue to raise the zebrafish inside the breeding chamber 2.

[0034] Example 2:

[0035] Combination Figure 2 and Figure 3 This embodiment, based on embodiment 1, further improves upon the following: Multiple support feet 12 are fixed to the bottom of the loading box 4. Screw sleeves 13 are embedded in the support feet 12. A screw rod rotatably connected to the inner wall of the bottom of the breeding chamber 2 is threaded through the internal threads of the screw sleeves 13. A rotating rod 14 is rotatably connected inside the drainage chamber 3. Transmission wheels are fixedly sleeved on the outer walls of both the screw rod and the rotating rod 14. A transmission belt is externally coupled to the transmission wheels. Multiple cams 15 that cooperate with the filter screen 10 are fixedly sleeved on the outer wall of the rotating rod 14. When the loading box 4 moves vertically, it will drive the support feet 12 to move vertically. At this time, the displacement of the support feet... The support leg 12 will drive the screw sleeve 13 to move vertically. At this time, the screw sleeve 13 will drive the screw to rotate. Through the transmission wheel and transmission belt, the rotating rod 14 will be driven to rotate. The rotating rod 14 will drive the cam 15 to rotate. The rotating cam 15 will intermittently press the filter screen 10, causing the filter screen 10 to vibrate. The vibrating filter screen 10 will unclog the filter holes, thereby preventing the filter holes of the filter screen 10 from being blocked by debris in the water after long-term operation, improving the filter screen 10's endurance and high working performance.

[0036] Example 3:

[0037] Combination Figure 4 , Figure 9 and Figure 10 This embodiment, based on embodiment 1, further improves upon the following: A drive column is fixed to the bottom of one end of the sealing box 5. The end of the drive column away from the sealing box 5 is rotatably connected to a loading shell fixed to the box body 1. A motor is fixed inside the loading shell. The motor is a forward and reverse stepper motor. A transmission column is connected to the output end of the motor. The end of the transmission column away from the motor extends to the outside of the loading shell and is fixedly sleeved with a drive gear 16. A driven gear that meshes with the drive gear 16 is fixedly sleeved on the outer wall of the drive column. A support leg 27 is hinged to the outside of the sealing box 5. A groove 28 is opened at the bottom of the support leg 27. A slider 29 is slidably connected inside the groove 28. A bolt 30 is threadedly connected to the bottom of the support leg 27. Multiple threaded grooves are opened on the side of the slider 29 near the bolt 30. The bolt 30 is threadedly connected inside the adjacent threaded grooves. When the breeder needs to open the box during use, When the body 1 is open, the winding column 8 rotates to wind up the winding rope 9, which pulls the loading box 4 to move vertically upward. After the loading box 4 enters the storage cavity 7, the motor 1 drives the drive column to rotate, which in turn drives the drive gear 16 to rotate. Through the cooperation of the drive gear 16 and the driven gear, the driven gear is driven to rotate. At this time, the rotating driven gear will drive the drive column to rotate, which will drive the sealing box 5 to rotate. After the sealing box 5 opens the body 1, the bolt 30 can be rotated to move the bolt 30. When the bolt 30 is disengaged from the adjacent threaded groove, the slider 29 can be pulled. When the slider 29 contacts the ground, the bolt 30 can be rotated to move the bolt 30. When the bolt 30 enters the adjacent threaded groove, the sealing box 5 is supported by the slider 29 and the support leg 27. At this time, the user can easily use the breeding box.

[0038] The bottom of the sealing box 5 has an opening 17 that communicates with the storage cavity 7. The loading box 4 slides and works in conjunction with the opening 17, allowing the loading box 4 to move flexibly through the opening 17.

[0039] Example 4:

[0040] Combination Figure 5-8This embodiment, based on Embodiment 1, further improves upon the following: the feeding assembly includes a feeding cylinder 18 that slides inside the feeding chamber 6. A discharge port 21, which slides and cooperates with the feeding cylinder 18, is located at the bottom of one end of the feeding chamber 6. A flat block 19, fixed to the inner wall of the top of the feeding chamber 6, is located above the discharge port 21. Discharge plates 26, fixed to the inner wall of the feeding chamber 6, are located on both sides of the feeding cylinder 18. A transmission block 24 is fixed to the outside of the feeding cylinder 18. A threaded sleeve 25 is embedded in the transmission block 24. A worm gear 20 passes through the inside of the threaded sleeve 25. A groove is formed on the outer wall of the worm gear 20. The feed chamber 6 has an external thread that mates with the internal thread of the threaded sleeve 25. A push plate 22 is slidably connected to the end of the feed chamber 6 furthest from the feeding cylinder 18. A connecting shaft is rotatably connected to the side of the push plate 22 furthest from the feeding cylinder 18. A cam 23, which works in conjunction with the push plate 22, is fixedly sleeved on the outer wall of the connecting shaft. A worm wheel, which meshes with the worm gear 20, is also fixedly sleeved on the outer wall of the connecting shaft. A sliding groove is formed on the inner wall of the top of the feed chamber 6. A sliding block, fixed to the push plate 22, is slidably connected inside the sliding groove. Multiple push springs, with their other ends fixed to the sliding blocks, are fixed to the inner wall of the sliding groove. Furthermore, when the breeder needs to feed the zebrafish in the rearing chamber 2, the rotation of the worm gear 20, through the threaded engagement between the worm gear 20 and the threaded sleeve 25, causes the threaded sleeve 25 to move, thereby moving the feeding cylinder 18. When the feeding cylinder 18 separates from the flat block 19 and enters the fish food inside the feeding chamber 6, the fish food inside the feeding chamber 6 will enter the feeding cylinder 18 through the opening on the top plate. When the feeding cylinder 18 is full of fish food, the reverse rotation of the worm gear 20 can be used to move the feeding cylinder 18... In the reverse displacement, when the feeding cylinder 18 contacts the flat block 19, the excess fish food at the top of the feeding cylinder 18 can be scraped off by the flat block 19. When the feeding cylinder 18 passes the discharge port 21, the fish food inside the feeding cylinder 18 will enter the discharge port 21. The fish food entering the discharge port 21 will then enter the breeding chamber 2 through the discharge port 21 and the opening 17, thereby feeding the zebrafish inside the breeding chamber 2. The above operation can be repeated according to the number of zebrafish inside the breeding chamber 2 until the feeding is finished, thereby achieving precise control of the amount of fish food.

[0041] A second motor is fixed to the inner wall of one end of the feeding chamber 6. The second motor is a forward and reverse reversible motor. One end of the worm gear 20 is connected to the output end of the second motor, and the other end of the worm gear 20 is rotatably connected to the inner wall of the feeding chamber 6. The push plate 22 has a rotating hole, and the worm gear 20 rotates inside the rotating hole. The operation of the second motor can drive the worm gear 20 to rotate. The worm gear 20 can rotate flexibly through the rotating hole.

[0042] The bottom of the loading box 4 is provided with a support frame 31 fixed to the inner wall of the breeding chamber 2. A sliding opening is provided on the inner wall between the breeding chamber 2 and the drainage chamber 3. The transmission belt slides inside the sliding opening. The loading box 4 can be supported by the support frame 31, and the transmission belt can slide flexibly through the sliding opening.

[0043] The top of the sealing box 5 is equipped with a feeding valve that communicates with the feeding chamber 6. The feeding valve is located between the feeding cylinder 18 and the push plate 22. Through the feeding valve, a sufficient amount of fish food can be injected into the feeding chamber 6. When the worm gear 20 rotates, it will drive the worm wheel to rotate. At this time, the rotating worm wheel will drive the connecting shaft to rotate. At this time, the rotating connecting shaft will drive the second cam 23 to rotate. At this time, the rotating cam 23 will intermittently push the push plate 22. The pushed push plate 22 will push the fish food inside the feeding chamber 6, preventing the fish food inside the feeding chamber 6 from accumulating in a peak shape, which would cause the feeding valve to be blocked and prevent the user from injecting fish food into the feeding chamber 6.

[0044] The leveling block 19 has an L-shaped structure. The bottom of the leveling block 19 slides in conjunction with the top of the feeding cylinder 18. The leveling block 19 can scrape away the fish food accumulated on the top of the feeding cylinder 18, thereby effectively increasing the amount of fish food inside the feeding cylinder 18 and improving the feeding accuracy.

[0045] A motor three is fixed to the inner wall of one end of the storage cavity 7. The motor three is a forward and reverse stepper motor. One end of the winding column 8 is connected to the output end of the motor three, and the other end of the winding column 8 is rotatably connected to the inner wall of the storage cavity 7. The winding rope 9 slides inside the opening 17. The winding column 8 can be driven to rotate by the operation of the motor three.

[0046] Working Principle: When zebrafish need to be raised, sufficient water can be injected into the tank 1. After the water is injected, the zebrafish can be placed into the breeding chamber 2 for feeding. When it is necessary to feed the zebrafish in the breeding chamber, the rotation of the worm gear 20, through the threaded engagement between the worm gear 20 and the threaded sleeve 25, drives the threaded sleeve 25 to move, which in turn drives the feeding cylinder 18 to move. When the feeding cylinder 18 separates from the flat block 19 and enters the fish food in the feeding chamber 6, the fish food in the feeding chamber 6 will enter the feeding cylinder 18 through the opening on the top plate of the feeding cylinder 18. When the feeding cylinder 18 is full of fish food, the reverse rotation of the worm gear 20 can drive the feeding cylinder... 18 moves in the reverse direction. When the feeding cylinder 18 contacts the flat block 19, excess fish food at the top of the feeding cylinder 18 can be scraped off by the flat block 19. When the feeding cylinder 18 passes the discharge port 21, the fish food inside the feeding cylinder 18 will enter the discharge port 21. The fish food entering the discharge port 21 will then enter the breeding chamber 2 through the discharge port 21 and the opening 17, thus feeding the zebrafish inside the breeding chamber 2. The above operation can be repeated according to the number of zebrafish in the breeding chamber 2 until the feeding is finished, thereby achieving precise control of the amount of fish food. When the worm gear 20 rotates, it will drive the worm wheel to rotate. The rotating worm wheel will drive the connecting shaft to rotate. The shaft will drive cam 23 to rotate. The rotating cam 23 will intermittently push push plate 22, which in turn pushes the fish food inside the feeding chamber 6, preventing the fish food from accumulating in a peak shape and clogging the feeding valve, thus preventing the user from injecting fish food into the feeding chamber 6. When the zebrafish in the tank 1 have been kept for a period of time and the water needs to be changed, the butterfly valve can be opened. At this time, the water in the breeding chamber 2 and the drainage chamber 3 can be drained through the drain pipe 11. The filter screen 10 will filter the water in the breeding chamber 2, preventing the zebrafish inside from entering the loading box 4 as the water flows out, thus preventing them from entering the drain pipe. The water inside tank 11 is drained through drain pipe 11, and then the zebrafish can be carried by loading box 4. After the water inside tank 1 is drained, the winding rope 9 can be wound up by rotating the winding column 8. At this time, the winding rope 9 will pull the loading box 4 to move vertically upward. After the loading box 4 enters the storage chamber 7, the breeder can inject new water into the tank 1. After the new water is injected, the winding rope 9 can be released by rotating the winding column 8. At this time, the loading box 4 will move vertically downward. After the loading box 4 enters the breeding chamber 2, the zebrafish inside the loading box 4 will swim out of the loading box 4 and enter the breeding chamber 2. At this time, the breeder can continue to raise the zebrafish in the breeding chamber 2.Furthermore, when the loading box 4 moves vertically, it will cause the support leg 12 to move vertically as well. This movement of the support leg 12 will then cause the threaded sleeve 13 to move vertically, which in turn will drive the screw to rotate. Through the transmission wheel and belt, this will drive the rotating rod 14 to rotate. The rotating rod 14 will then drive the cam 15 to rotate, intermittently pressing the filter screen 10 and causing it to vibrate. This vibration will unclog the filter pores, preventing them from becoming clogged with debris after prolonged use. This improves the filter screen's endurance and performance. When the user needs to open the box 1 during use, the filter screen can be retracted... The rotation of the winding column 8 retracts the winding rope 9, which pulls the loading box 4 vertically upward. Once the loading box 4 enters the storage cavity 7, the operation of motor 1 drives the drive column to rotate, which in turn drives the drive gear 16. Through the cooperation of the drive gear 16 and the driven gear, the driven gear rotates, which in turn drives the drive column to rotate, causing the sealing box 5 to rotate. When the sealing box 5 opens the box body 1, the bolt 30 can be rotated, causing it to move. Once the bolt 30 disengages from the adjacent threaded groove, the slider 29 can be pulled. When the slider 29 contacts the ground, the bolt 30 can be rotated, causing it to move. When the bolt 30 enters the adjacent threaded groove, the sealing box 5 is supported by the slider 29 and the support leg 27, allowing the user to easily operate the breeding box.
