Abstract
Description
Technical Field
[0001] The utility model relates to the field of aquaculture equipment technology, and in particular to a shrimp pond sampling device. Background Technology
[0002] A feed net is a mesh device placed at the bottom of a shrimp pond to hold feed, allowing farmers to observe the shrimp's feeding behavior. Through the feed net, farmers can determine the shrimp's appetite, health status, and whether the feeding amount is appropriate. Due to technological advancements, many shrimp feeding devices now include mechanisms for automatically sinking and retrieving the feed net periodically. Using these devices, the sinking and retraction of the feed net are automatically controlled. The feed net is typically lowered to the bottom and pulled out of the water using a lifting rope. Therefore, once the feed net has sunk to the bottom of the shrimp pond, the lifting rope no longer needs to be loosened. When the feed net is pulled out of the water, an image sampler is activated to photograph it. The size of the shrimp in the photos and the amount of feed at different times are then analyzed to determine the shrimp's feeding status, thus achieving automatic feeding and monitoring. Therefore, determining whether the feed net has been placed at the bottom of the shrimp pond and whether it has been pulled out of the water is crucial for the proper functioning of the equipment.
[0003] The technical content disclosed in the Chinese patent document (publication number: CN202773753U, patent name: a trap suitable for fish and shrimp polyculture) is as follows: it includes a trap frame and a trap net sleeve wrapped around the trap frame. The trap net sleeve is made by sewing together a feed net sleeve for holding feed for polycultured shrimp and an isolation net sleeve for preventing polycultured fish from entering the trap. The mesh size of the isolation net sleeve should be selected according to the size of the polycultured fish. It is larger than the body size of the polycultured shrimp but smaller than the body size of the polycultured fish. In this way, the polycultured shrimp can enter the trap to eat, while the polycultured fish cannot enter. In order to allow the shrimp to enter and exit freely to the maximum extent, the mesh size of the isolation net sleeve should be as large as possible.
[0004] As can be seen from the above implementation plan and the corresponding drawings, this fishing net does not have a mechanism to automatically lift and lower it into the water. Therefore, each time the situation in the net is observed, it is necessary to manually lift the net, which is more time-consuming and labor-intensive than automated equipment. Utility Model Content
[0005] The utility model overcomes the shortcomings of the prior art and provides a shrimp pond sampling device with a high degree of automation, which is conducive to precise control and has an ingenious structure.

[0034] The preferred embodiments of the utility model are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the utility model.
[0035] like Figures 1 to 10 As shown, a shrimp pond sampling device includes a lifting power mechanism 5, an image sampler 6 is arranged on the side of the lifting power mechanism 5, the lifting power mechanism 5 is connected to a lifting rope 3, and the lifting rope 3 is connected to a feeding net component; when the feeding net component is pulled out of the water by the lifting rope 3, the image sampler 6 is activated to take a picture of the feeding net component. The size of the shrimp in the picture and the amount of feed at different time periods are analyzed by the picture collected by the image sampler 6 to determine the shrimp feeding situation, thereby achieving the purpose of automatic feeding and monitoring.
[0036] The lifting power mechanism 5 includes a base 501, a motor base 503 and a trigger plate 507 hinged to the base 501, and a first limit switch 508 and a second limit switch 509 connected to the base 501. A spring 504 is provided between the base 501 and the motor base 503, and the spring 504 causes one side of the motor base 503 to be subjected to a spring force away from the base 501. The first limit switch 508 is located below the motor base 503. When the motor base 503 is pressed down, the first limit switch 508 is triggered. When the motor base 503 is lifted by the spring 504, the first limit switch 508 is reset.
[0037] Specifically, the motor mount 503 and the base 501 are connected by a first hinge 502, meaning that the motor mount 503 can rotate upwards or downwards relative to the base 501 via the first hinge 502; therefore, under normal conditions, it is as follows... Figure 6 As shown, spring 504 lifts one side of motor mount 503.
[0038] The motor base 503 has a spring connecting seat 5031 at the end away from the first hinge 502. The lower end of the spring 504 extends downward from the spring connecting seat 5031 and presses against the base 501. The spring connecting seat 5031 is threadedly connected to an adjusting bolt 505. A spring pressure block 5051 is provided at the end of the adjusting bolt 505. The spring 504 is located in the spring connecting seat 5031, and the spring pressure block 5051 abuts against one end of the spring 504. Rotating the bolt 505 can adjust the initial compression degree of the spring 504, thereby adjusting the preset elastic force of the spring 504 on the motor base 503. This allows the preset elastic force of the spring 504 on the motor base 503 to both lift the motor base 503 when the lifting rope 3 is slack, preventing it from pressing against the first limit switch 508, and to press the motor base 503 down against the first limit switch 508 when the lifting rope 3 is taut.
[0039] Motor base 503 is connected to motor 506, motor 506 is connected to rod 5061, lifting rope 3 is wound around rod 5061, motor 506 rotates to make rod 5061 rotate, and rod 5061 achieves the winding and unwinding of lifting rope 3 by rotating forward or backward.
[0040] By setting a preset elastic force of spring 504 on motor base 503, the preset elastic force is made less than the weight of the feed net component. That is, when the feed net component sinks by releasing the lifting rope 3, the weight of the feed net component is greater than the elastic force of spring 504, so motor base 503 is in a swinging state. At this time, motor base 503 is pressed on the first limit switch 508. When the feed net component sinks to the bottom of the pond, the feed net component no longer has a pulling force on the lifting rope 3, that is, no longer has a pulling force on motor base 503. At this time, motor base 503 will swing upward under the elastic force of spring 504 and no longer has pressure on the first limit switch 508.
[0041] In this embodiment, both the first limit switch 508 and the second limit switch 509 are electrically connected to the motor 506. When the lifting rope 3 is being released, that is, when the feeder component sinks, the first limit switch 508 is triggered and transmits a signal to the motor 506, causing the motor 506 to stop rotating and releasing the rope. When the lifting rope 3 is being retracted, that is, when the feeder component rises, the second limit switch 509 is triggered and transmits a signal to the motor 506, causing the motor 506 to stop rotating and retracting the rope.
[0042] like Figure 3 as well as Figure 4 It can be seen that the trigger plate 507 and the base 501 are connected by the second hinge 5071, so the outer end of the trigger plate 507 can swing up and down relative to each other; combined with Figure 2 as well as Figure 3See, the trigger plate 507 has a wire groove, and the lifting rope 3 passes through the wire groove from top to bottom; the lifting rope 3 also has a limit member 4, the volume of which is larger than the width of the wire groove. Therefore, when the lifting rope 3 is retracting the wire, when the limit member 4 moves upward and enters the wire groove, the lifting rope 3 can pull the trigger plate 507 to rotate upward; from Figure 3 It can be seen that the trigger rod of the second limit switch 509 is connected to the outer end of the trigger plate 507. That is, when the trigger plate 507 swings upward under the action of the limit member 4, it will drive the trigger rod of the second limit switch 509 to move. At this time, the second limit switch 509 will transmit a signal to the motor 506, and the motor 506 will stop rotating and take in the wire.
[0043] In practical design, a spring can be incorporated into the base 501 to press down on the outer end of the trigger plate 507. As the lifting rope 3 rises, it causes the limiting member 4 to move upward, lifting the trigger plate 507. During the unloading process, the spring will push the outer end of the trigger plate 507 back down to reset it. Adding this spring to reset the trigger plate 507 helps improve the stability of the equipment operation.
[0044] Therefore, during the process of lowering the feed net component to the bottom of the pond, the lifting rope 3 is in a taut state. At this time, the tension of the feed net component on the motor base 503 through the lifting rope 3 causes the motor base 503 to compress the spring 504, thereby pressing the first limit switch 508. Until the feed net component reaches the bottom of the pond, the lifting rope 3 loosens, the tension of the feed net component on the motor base 503 through the lifting rope 3 decreases or even disappears, the elastic force of the spring 504 lifts the motor base 503, and the motor base 503 no longer applies pressure to the first limit switch 508. The first limit switch 508 is triggered, and the signal is transmitted to the motor 506 to stop the machine. The lifting rope 3 stops being released.
[0045] When the wire is being wound up, when the feeder is pulled to the top, the limiter 4 presses against the lower end of the trigger plate 507 and pulls it upward. When the trigger plate 507 is pushed upward, it moves the trigger rod of the second limit switch 509 upward. The second limit switch 509 is triggered and the signal is transmitted to the motor 506 to stop the machine. The lifting rope 3 stops winding.
[0046] That is, both the first limit switch 508 and the second limit switch 509 are used to control the motor 506 to stop. The first limit switch 508 is used to control the stop of wire feeding; the second limit switch 509 is used to control the stop of wire taking.
[0047] In this embodiment, the tension and relaxation of the lifting rope 3 triggers the first limit switch 508 to determine whether the feed net component has been placed at the bottom of the pond. In addition, the limit member 4 set on the lifting rope 3 presses against the trigger plate 507, causing the second limit switch 509 to be triggered, thus confirming that the feed net component has been pulled out of the water. This achieves the purpose of automatically monitoring the feeding and production of shrimp by the equipment. The shrimp pond is automatically monitored by the equipment, saving the time and energy of the farmers.
[0048] In this embodiment, the first limit switch 508 is a limit switch or a micro switch, and the second limit switch 509 is a limit switch or a micro switch.
[0049] A limit guide post 5011 is provided on the base 501. The motor base 503 is movably inserted into the limit guide post 5011. Since the motor base 503 swings up and down at a certain angle, an elliptical groove is provided on the motor base 503 corresponding to the limit guide post 5011. The limit guide post 5011 is relatively movably inserted into the elliptical groove, which does not affect the movement of the motor base 503. The limit guide post 5011 is threadedly connected to a limit nut 5012. The limit nut 5012 is located above the motor base 503. The limit nut 5012 restricts the motor base 503 so that it is inserted into the limit guide post 5011 and will not come out. Adjusting the limit nut 5012 can also adjust the distance between one side of the motor base 503 and the base 501. This distance is greater than or equal to the switching stroke distance of the first limit switch 508.
[0050] That is, the tilt of the motor base 503 is controlled by multiple components such as the limiting guide post 5011, the limiting nut 5012, the spring 504, and the spring connecting seat 5031.
[0051] The lifting power mechanism 5 is located at the center of the top of the frame 7, and the lower end of the frame 7 is provided with a buoyancy component 8. The buoyancy component 8 can float the frame 7 on the water surface, so that the feed net component can be placed in the middle of the shrimp pond, making it convenient for the shrimp to feed. In this embodiment, the buoyancy component 8 is a float.
[0052] The feeding net component includes a feeding net 1 and a counterweight 2. The feeding net 1 surrounds an upward-facing accommodating space. Feed can be placed into this accommodating space. When the feeding net 1 is scooped up, some fish and shrimp will also be in this accommodating space. At this time, the feeding progress and growth of the fish and shrimp can be observed by taking pictures with an image sampler or manually. The feeding net 1 is provided with a central hole 1011, through which a lifting rope 3 is movably inserted. The lower end of the lifting rope 3 is connected to the counterweight 2. The feeding net 1 includes a feeding net body 101, with the central hole 1011 located at the center of the feeding net body 101. The bottom surface of the feeding net body 101 is also provided with mesh holes. In this embodiment, the image sampler is a camera.
[0053] The periphery of the net body 101 is connected to the connecting piece 102 via a connecting rope 104. The connecting piece 102 is slidably sleeved on the lifting rope 3. A limiting post 103 is connected to the lifting rope 3 to restrict the connecting piece 102. Therefore, when the net body 101 sinks, the connecting piece 102 slides down the lifting rope 3 and stops when it reaches the position of the limiting post 103. When the lifting rope 3 is pulled up, the limiting post 103 will push against the connecting piece 102 and pull it up, thereby pulling the net body 101 up. When the net 101 is pulled out of the water, water flows down from the mesh of the net body 101, so that the inside of the net body 101 is not filled with water, which makes it easy for the image sampler to take pictures and observe, and also easy for the human eye to see.
[0054] When the feeder 1 is deployed, the counterweight 2 sinks and straightens the lifting rope 3. The feeder 1 descends along the lifting rope 3 until the connecting piece 102 stops against the limiting post 103. The counterweight 2 sinks to the bottom of the water first. Since the counterweight 2 does not descend slowly due to the mesh being blocked like the feeder 1, the lifting rope 3 will not slacken during the descent of the counterweight 2, thus preventing equipment misjudgment and ensuring the stability of the control mechanism. When the feeder 1 descends along the lifting rope 3, the lifting rope 3 also guides the feeder 1, making the descent of the feeder 1 more stable.
[0055] The outer diameter of the counterweight 2 is larger than the inner diameter of the central hole 1011, so it will not be pulled up and enter the feeder body 101.
[0056] The side wall of the material tray body 101 is inclined relative to the bottom surface. The bottom inner diameter of the material tray body 101 is smaller than the opening inner diameter of the material tray body 101. This makes the accommodating space an upward-opening container, which makes it easy for equipment or personnel to put materials into the accommodating space. It also ensures that the image sampler will not be obstructed when taking pictures of the inside of the accommodating space.
[0057] Three or more connecting ropes 104 are connected at equal intervals to the main body of the net 101, so that there are traction points on all four sides of the main body of the net 101, thus ensuring that the main body of the net 101 remains stable whether it is rising or falling.
[0058] The material net body 101 is also equipped with an internal support frame, which strengthens the internal structure of the material net body 101, making the material net body 101 more stable and less prone to deformation even if it is impacted during operation.
[0059] Finally, it should be noted that the above are merely preferred embodiments of the utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the utility model should be included within the protection scope of the utility model.
