Description

Technical Field

[0001] This utility model relates to the field of fish fry cultivation technology, specifically to an automatic feeding device for fish fry cultivation ponds. Background Technology

[0002] Aquaculture is a production activity involving the breeding, cultivation, and harvesting of aquatic plants and animals under human control. It generally includes the entire process of raising fish fry into aquatic products under artificial feeding and management. In the process of fish farming, when raising fish fry, it is necessary to put feed into the rearing pond in a timely manner to feed the fish fry and maintain their normal growth.

[0003] A search revealed prior art publication number CN221264862U, which discloses an automatic feeding device for fish fry rearing ponds. The device includes a base with a second rotating shaft at its top, the bottom of which is rotatably connected to the top of the base. A turntable is connected to the top of the second rotating shaft, one side of which is connected to a rotating mechanism. A feed hopper is located on the top of the turntable, and several legs are evenly spaced along the bottom edge of the feed hopper. The bottom of the legs is fixed to the turntable. A discharge pipe is installed at the bottom of the feed hopper, and a conveying mechanism is located inside the discharge pipe. This application uses a first motor to control the rotation of spiral blades, conveying feed into the discharge pipe. Simultaneously, a high-speed air blown by a high-pressure fan propels the feed into the rearing pond for feeding. During the feeding process, a second motor drives gears and a gear ring to rotate, thereby adjusting the horizontal rotation direction of the discharge pipe, increasing the feed distribution area, and improving the feeding effect.

[0004] However, existing technologies cannot dynamically adjust the feeding amount based on the real-time feeding intensity of fish fry. This leads to feed settling and rotting at the bottom and increasing ammonia nitrogen levels when overfeeding, while underfeeding inhibits the growth of fish fry. At the same time, feeding devices generally lack direct means of sensing feeding sound waves and can only rely on timed or manual observation.

[0005] Therefore, based on the above-mentioned search and combined with existing technologies, an automatic feeding device for fish fry rearing ponds is proposed to solve the above problems. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0022] In one typical implementation of this application, please refer to Figures 1-4 As shown, an automatic feeding device for a fish fry rearing pond includes: a floating plate 1, a feeding device body 2 fixedly installed on the top surface of the floating plate 1, the floating plate 1 being connected to the shore via a steel wire rope, a discharge port 3 being provided on the front side wall of the feeding device body 2, a sealing plate 4 being provided on one side of the discharge port 3 via an installation component, a hydrophone 5 being fixedly installed on the bottom surface of the floating plate 1, the hydrophone 5 detecting the specific sound wave spectrum of the fish fry biting the bait, and a controller 12 being fixedly installed on the top surface of the floating plate 1.

[0023] The mounting components include: mounting plate 6, which is fixedly mounted on the front side wall of the floating plate 1 and located above the sealing plate 4. The bottom surface of the mounting plate 6 has a moving groove 7.

[0024] The mounting assembly also includes: a limiting rod 8, which is fixedly installed on the inner wall of the moving groove 7, and a moving block 9 is slidably installed on the limiting rod 8. The moving block 9 slides in the moving groove 7. The mounting assembly also includes a driving component.

[0025] The driving component includes an electromagnet 10, which is fixedly installed on the left side of the inner wall of the moving groove 7. A spring 11 is provided on the right side of the inner wall of the moving groove 7. The spring 11 is sleeved in the limiting rod 8. The left side wall of the spring 11 is connected to the right side wall of the moving block 9. The moving block 9 is made of iron material and can be attracted to the electromagnet 10 when it is energized.

[0026] Based on the above characteristics, the hydrophone 5 detects the specific sound wave spectrum of the fish fry biting the bait and transmits the data to the controller 12. The controller 12 controls the strength of the electromagnet 10 according to the data transmitted by the hydrophone 5. Specifically, when the hydrophone 5 detects that the fish fry are feeding quickly, the electromagnet 10 is at its maximum strength. At this time, the sealing plate 4 is at the far right, so that the feed in the feeding device body 2 is discharged into the rearing pond through the discharge port 3. Conversely, when the hydrophone 5 detects that the fish fry are feeding gradually decreases, the controller 12 will gradually reduce the strength of the electromagnet 10, so that the moving block 9 is restored to its initial position under the action of the spring 11. At this time, the sealing plate 4 seals the discharge port 3 again.

[0027] Multiple observation windows 13 are provided on both sides of the feeding device body 2, and the multiple observation windows 13 are all made of transparent glass.

[0028] Working principle:

[0029] In use, the floating plate 1 is connected to the shore with a steel wire rope, so that the whole device floats stably on the surface of the rearing pond. After starting, the hydrophone 5 collects the specific sound wave spectrum generated when the fish fry bite the feed in the pond in real time and transmits the signal to the controller 12 in real time. The controller 12 judges the current feeding intensity based on the preset threshold: when the hydrophone 5 detects a high-frequency strong signal, it indicates that the fish fry are feeding actively. The controller 12 immediately increases the current of the electromagnet 10, and the electromagnet 10 generates the maximum attraction force, attracting the iron moving block 9 to slide to the left against the elastic force of the spring 11, driving the sealing plate 4 to fully open the feed outlet 3 to the right, and the feed is quickly discharged from the feeding device body 2; as the feeding intensity decreases, the output signal of the hydrophone 5 weakens, the controller 12 gradually reduces the current of the electromagnet 10, the attraction force weakens, the restoring force of the spring 11 pushes the moving block 9 to reset to the right, and the sealing plate 4 moves to the left and gradually closes the feed outlet 3 until it is completely closed, and the feeding stops. The observation window 13 is used for manual real-time monitoring of the remaining material in the hopper; the guide mechanism consisting of the mounting plate 6, the moving groove 7, and the limit rod 8 ensures that the reciprocating motion of the sealing plate 4 is smooth and without jamming.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
