Description

Technical Field

[0001] This utility model relates to the field of fish fry breeding technology, specifically: a fish fry sampling device for fish fry breeding. Background Technology

[0002] Fish fry, also known as fry, are newly hatched juvenile fish, generally 6-9 mm in length. The cultivation of fish fry, from the selection of broodstock to successful conception, hatching, and growth, requires meticulous and responsible management. Managers must be fully committed, constantly monitoring the growth of the fish fry and changes in the environment, and providing timely and appropriate countermeasures. Only with proper handling can successful cultivation be achieved. During this process, fish fry sampling devices are needed to observe the fish fry.

[0003] Chinese patent CN216314938U discloses a fish fry sampling device for fish fry breeding, including a fish fry sampling box. An air chamber is fixedly connected to the top of the sampling box, and an air injection pipe is connected to the top of the air chamber. A feed box is fixedly connected to the bottom of the inner wall of the sampling box. The left and right sides of the inner wall of the sampling box have U-shaped notches. This invention, by incorporating a rubber flexible plate and a sealing plate, allows fish fry to enter the sampling box through the U-shaped notches. The user can then pull the sampling box upwards by pulling a rope, sealing the sampling box with the rubber flexible plate and sealing plate, preventing water from flowing out. This solves the problem of existing fish fry sampling devices directly removing fish fry from the water during capture, which can damage the fry and lead to a lower survival rate after release, resulting in resource waste. This invention has the advantage of not harming the fish fry during capture.

[0004] While the aforementioned patents offer some improvements in fish fry sampling, there is still room for further enhancement. For example, prolonged exposure of fish fry inside the sampling device may lead to insufficient oxygen supply, resulting in a decrease in dissolved oxygen levels in their environment and potentially causing hypoxia. This hypoxia can adversely affect the normal physiological functions of the fish fry and may even threaten their survival and health.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes a fish fry sampling device for fish fry breeding, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0008] Furthermore, a sealing ring is fixedly connected to the inner wall of one of the through holes, and the inner wall of the sealing ring is fixedly connected to the outer surface of the oxygen delivery tube.

[0009] Furthermore, the inner wall of the sampling box is fixedly connected with symmetrical fish-attracting tubes, and the ends of the two fish-attracting tubes that are close to each other are threaded with tube caps.

[0010] Furthermore, fish inlet hoppers are fixedly connected to both the left and right sides of the sampling box, and each fish inlet hopper is a conical cylinder.

[0011] Furthermore, a sealing plate is fixedly connected to the front of the sealed box by fasteners, and a sealing strip is fixedly connected to the inner wall of the sealed box. The back of the sealing plate is in contact with the outer surface of the sealing strip.

[0012] Furthermore, the inner bottom wall of the sealed box is fixedly connected with symmetrical support columns, and the top of each support column is fixedly connected to the inner top wall of the sealed box.

[0013] Furthermore, the upper surface of the sampling box is hinged with a cover plate, the bottom surface of the cover plate is fixedly connected with symmetrical locking posts, and the inner wall of the sampling box is fixedly connected with symmetrical locking slots, with the two locking posts respectively engaging with the two locking slots.

[0014] The beneficial effects of this utility model are as follows: By powering the oxygenation pump with the battery module, the pump delivers oxygen through the oxygen supply tube to the sampling inner frame, increasing the oxygen level within the frame. A sealing ring improves the seal between the oxygen supply tube and the through-hole, preventing oxygen leakage and thus avoiding prolonged stays of fish fry inside the sampling device. Insufficient oxygen supply can lead to a decrease in dissolved oxygen levels in the fry's environment, causing hypoxia, which can negatively impact their normal physiological functions and even threaten their survival and health. This design achieves the goal of catching fish fry without harming them. The addition of a fish-attracting tube and lid allows for the placement of food the fry like inside, attracting them into the sampling box and improving the ease of sampling. A conical fish-entry hopper further facilitates the entry of fish fry into the sampling box. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-5 As shown in the embodiment of this utility model, a fish fry sampling device for fish fry breeding is provided, comprising: a sampling box 1, a sealing box 2 fixedly connected to the bottom surface of the sampling box 1, a sampling inner frame 3 fixedly connected to the inner bottom wall of the sampling box 1, through holes 4 provided in the inner bottom wall of the sampling box 1, the inner top wall of the sealing box 2 and the inner bottom wall of the sampling inner frame 3, an oxygen pump 5 fixedly installed in the inner bottom wall of the sealing box 2, an oxygen supply pipe 6 fixedly connected to the output end of the oxygen pump 5, the end of the oxygen supply pipe 6 away from the oxygen pump 5 passing through the through hole 4 and extending into the interior of the sampling inner frame 3, and a symmetrical battery module 7 fixedly installed in the inner bottom wall of the sealing box 2. Through the above scheme, the output end of the battery module 7 is electrically connected to the oxygen pump 5 to provide power to the oxygen pump 5. Using the oxygen pump 5, the oxygen pump 5 injects oxygen into the interior of the sampling inner frame 3 through the oxygen supply pipe 6, thereby maintaining sufficient oxygen inside the sampling inner frame 3, preventing the fish fry from dying due to lack of oxygen, and ensuring the safety of the fish fry during the sampling process.

[0024] Continue to refer to Figures 1-5 One of the through holes 4 has a sealing ring 8 fixedly connected to its inner wall. The inner wall of the sealing ring 8 is fixedly connected to the outer surface of the oxygen supply tube 6. The sealing ring 8 improves the sealing between the oxygen supply tube 6 and the through hole 4, preventing oxygen leakage and ensuring that oxygen can be stably delivered to the inside of the sampling inner frame 3. In addition, the sealing ring 8 also fixes the oxygen supply tube 6, preventing it from shaking or falling off during use, further improving the stability and reliability of the device. The inner wall of the sampling box 1 is fixedly connected to symmetrical fish attracting tubes 9. The ends of the two fish attracting tubes 9 that are close to each other are threaded with tube caps 10. Each fish attracting tube 9 has several ventilation holes. The ventilation holes can attract fish fry. The left and right sides of the sampling box 1 are fixedly connected to fish inlet hoppers 11. Each fish inlet hopper 11 is a conical tube with its large opening facing outward. This design facilitates the smooth entry of fish fry into the sampling box 1, reduces the obstruction of the fish fry during the entry process, and improves the sampling efficiency.

[0025] Continue to refer to Figures 1-5A sealing plate 12 is fixedly connected to the front of the sealed box 2 by fasteners, and a sealing strip 13 is fixedly connected to the inner wall of the sealed box 2. The back of the sealing plate 12 contacts the outer surface of the sealing strip 13. The sealing strip 13 enhances the sealing performance between the sealing plate 12 and the sealed box 2, effectively preventing external air or moisture from entering the interior of the sealed box 2, ensuring the dryness and cleanliness of the sampling box 1, and providing a good living environment for the fish fry. At the same time, the sealing strip 13 also acts as a buffer, reducing the impact force between the sealing plate 12 and the sealed box 2 when the sealing plate 12 is closed, thus extending the service life of the device. In addition, the sealing plate 12 is fixedly connected to the front of the sealed box 2 by fasteners. This connection method is both firm and easy to disassemble, making it convenient for users to maintain and clean the sampling device.

[0026] Continue to refer to Figures 1-5 The inner bottom wall of the sealed box 2 is fixedly connected with symmetrical support columns 14. The top of each support column 14 is fixedly connected to the inner top wall of the sealed box 2. This structural design not only enhances the structural strength of the sealed box 2 but also ensures its stability. The setting of the support columns 14 creates a stable space inside the sealed box 2, ensuring that the device can operate normally. The upper surface of the sampling box 1 is hinged with a cover plate 15. The bottom surface of the cover plate 15 is fixedly connected with symmetrical locking posts 16. The inner wall of the sampling box 1 is fixedly connected with symmetrical locking grooves 17. The two locking posts 16 are respectively connected to two locking grooves. The slot 17 is snapped in place, and the snap-fit ​​design between the snap-fit ​​post 16 and the slot 17 allows for easy and secure connection between the cover plate 15 and the sampling box 1, ensuring the sealing of the sampling box 1 and effectively preventing fish fry from jumping out of the sampling box 1 during sampling, thus improving sampling efficiency. At the same time, the connection method between the snap-fit ​​post 16 and the slot 17 is simple and practical, making it easy for users to open and close the cover plate 15, which greatly facilitates the fish fry sampling work. In addition, the cover plate 15 can also prevent external impurities or contaminants from entering the sampling box 1, further ensuring the survival environment of the fish fry and the accuracy of the sampling results.

[0027] In use, the user first connects the battery module 7 to an external power source. The battery module 7 provides power to the electrical components in this device. The user guides the fish fry into the sampling box 1 through the fish inlet 11. The fish attractant tube 9 attracts the fish fry into the sampling box 1. Once the fish fry are inside the sampling inner frame 3, the oxygen pump 5 is activated. The oxygen pump 5 injects oxygen into the sampling inner frame 3 through the oxygen supply tube 6, thus maintaining sufficient oxygen inside the sampling inner frame 3 and preventing the fish fry from dying due to lack of oxygen. When it is necessary to sample the fish fry, the user opens the cover plate 15. At this time, the locking post 16 separates from the locking slot 17. The user opens the cover plate 15 and then removes the sampling inner frame 3 from the sampling box 1. The fish fry inside the sampling inner frame 3 can then be sampled. After sampling, the user puts the sampling inner frame 3 back into the sampling box 1 and seals the sampling box 1 with the cover plate 15 to complete the sampling work.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
