Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, and in particular to a seedling release device for shrimp larvae. Background Technology

[0002] In modern aquaculture, especially shrimp farming, the stocking of shrimp larvae is crucial. Precise control of the stocking quantity directly affects farming efficiency, aquatic ecological balance, and the ease of subsequent management. Accurate stocking ensures shrimp populations grow at suitable densities, avoiding problems like intense food competition and disease transmission due to overcrowding, and preventing resource waste due to undercrowding. Traditional methods of counting shrimp larvae rely on manual labor, using small nets to scoop them out of holding containers one by one and count them. However, this manual method is labor-intensive and prone to accidents. Shrimp larvae are prone to fatigue, which reduces the accuracy and efficiency of counting. With the continuous advancement of technology, some automatic larvae counting devices have emerged. After capturing images of shrimp larvae through cameras, image recognition technology is used for counting. While ensuring accuracy, the counting efficiency can be improved. However, the active swimming characteristics of shrimp larvae have been overlooked in the current image acquisition process, affecting the accuracy of counting. Under normal lighting conditions, the high-speed swimming of shrimp larvae makes it difficult to clearly and completely obtain the accurate position and status information of each shrimp larvae, even with advanced image capture and analysis methods, thus affecting the final counting results. Utility Model Content

[0003] In view of this, the present invention proposes a seedling release device that can gradually reduce the brightness to slow down the movement of the shrimp seedlings, so as to facilitate the acquisition of accurate image data.

[0004] The technical solution of this utility model is implemented as follows:

[0005] A shrimp larvae release device includes a release box, a light-transmitting plate, a larvae inlet channel, a larvae outlet pipe, a valve, a night vision camera, and a light adjustment mechanism. The release box has an open top, the light-transmitting plate is located on the top of the release box, the larvae inlet channel is located on one side of the release box, the larvae outlet pipe is located on the bottom of the release box, the valve is located on the larvae outlet pipe, and the night vision camera is located on the bottom of the light-transmitting plate. The light adjustment mechanism includes a mounting plate, a roller, a rotary motor, a fully transparent film, and several light-blocking films. The mounting plates are positioned opposite each other on both sides of the release box, the roller is located between the mounting plates, the rotary motor is located on the side wall of the mounting plate, and its output shaft passes through the mounting plate and connects to the end of the roller. One side of the fully transparent film is fixed to the roller on one side, and the other side is connected to the light-blocking films connected in sequence above the light-transmitting plate. The light transmittance of the several light-blocking films gradually decreases from one side of the fully transparent film to the other side, and the light-blocking films are wrapped around the roller on the other side.

[0006] Preferably, it also includes a baffle, the top of which is rotatably connected to the inner wall of the seedling box via a hinge, and the seedling inlet channel is located on one side of the baffle.

[0007] Preferably, the illumination adjustment mechanism further includes a bearing and a rotating shaft. The bearing is mounted on a mounting plate away from the rotating motor, and the rotating shaft is located at the end of the roller away from the rotating motor and connected to the bearing.

[0008] Preferably, it also includes a semiconductor refrigeration chip, which is disposed at the bottom of the seedling box.

[0009] Preferably, the light adjustment mechanism further includes a guide wheel, which is inclinedly disposed on the side wall of the seedling box, and the bottom surface of the fully transparent film passes through the surface of the guide wheel.

[0010] Preferably, it also includes a cleaning mechanism, which includes an electric push rod, a moving plate, and a cleaning sponge.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] ① The culture water containing shrimp larvae is poured into the seedling box through the seedling inlet channel. After pouring, the image data containing the shrimp larvae can be collected by the night vision camera. Then, image recognition technology can be used to seed the larvae.

[0019] To better understand the technical content of this utility model, a specific embodiment is provided below, and the utility model will be further described in conjunction with the accompanying drawings.

[0020] See Figures 1 to 3 This utility model provides a seedling release device for shrimp larvae, comprising a seedling box 1, a light-transmitting plate 2, a seedling inlet channel 3, a seedling outlet pipe 4, a valve 5, a night vision camera 6, and a light adjustment mechanism. The seedling box 1 has an open top, the light-transmitting plate 2 is located on the top of the seedling box 1, the seedling inlet channel 3 is located on one side of the seedling box 1, the seedling outlet pipe 4 is located on the bottom surface of the seedling box 1, the valve 5 is located on the seedling outlet pipe 4, and the night vision camera 6 is located on the bottom surface of the light-transmitting plate 2. The light adjustment mechanism includes a mounting plate 7, a roller 8, and a rotary motor 9. The system comprises a fully transparent film 10 and several light-blocking films 11. The mounting plate 7 is arranged opposite each other on both sides of the seedling box 1. The roller 8 is located between the mounting plates 7. The rotary motor 9 is located on the side wall of the mounting plate 7, and its output shaft passes through the mounting plate 7 and is connected to the end of the roller 8. One side of the fully transparent film 10 is fixed on the roller 8 on one side, and the other side is connected to the light-blocking films 11 connected in sequence above the light-transmitting plate 2. The light transmittance of the several light-blocking films 11 gradually decreases from one side of the fully transparent film 10 to the other side. The light-blocking films 11 are wrapped around the roller 8 on the other side.

[0021] After dividing the breeding pond into several grid areas, shrimp larvae from one grid are taken and released into the seedling box 1 along with the breeding water through the seedling inlet channel 3. The top of the seedling box 1 is a light-transmitting plate 2, and the top of the light-transmitting plate 2 is a fully transparent film 10. This ensures that the brightness does not change excessively when the shrimp larvae are released into the seedling box 1. After the shrimp larvae are released, the rotary motor 9 is started. The rotary motor 9 drives the roller 8 to rotate, causing the fully transparent film 10 to wrap around one side of the roller 8. At the same time, the light-blocking film 11 on the other side of the roller 8 is continuously released. Since the light transmittance of the light-blocking film 11 continuously decreases, the fully transparent film 10 and the light-blocking film 11... As the light-emitting membrane 11 moves over the light-transmitting plate 2, the amount of light entering the seedling box 1 decreases, thus reducing the brightness inside the seedling box 1. Since shrimp larvae are phototactic, their activity slows down as the brightness decreases. At this time, the night vision camera 6 can collect image data of the cleaned shrimp larvae. This image data can be transmitted to a computer, where the number of shrimp larvae can be calculated through image recognition, achieving precise seedling selection. Compared to traditional seedling selection methods, this method can obtain the number of shrimp larvae more accurately. The number of shrimp larvae in the seedling box 1 can then be used to map the total number of shrimp larvae in the entire breeding pond, providing data support for shrimp larvae farming.

[0022] When the fully transparent membrane 10 and the light-blocking membrane 11 move above the light-transmitting plate 2, they can move intermittently. That is, the light-blocking membrane 11 is first allowed to stay on the light-transmitting plate 2 for a period of time before the next light-blocking membrane 11 is moved. This allows the shrimp larvae to adapt to the reduced brightness environment and avoids stress on the shrimp larvae. After the seeding is completed, the fully transparent membrane 10 and the light-blocking membrane 11 can move in opposite directions. Finally, the fully transparent membrane 10 moves to the top of the light-transmitting plate 2, so that the brightness inside the seeding box 1 is consistent with the outside. After maintaining this for a period of time, the valve 5 is opened, allowing the shrimp larvae and the culture water to be discharged to the outside through the valve 5, thus completing the entire seeding process.

[0023] Preferably, it also includes a baffle 12, the top of which is rotatably connected to the inner wall of the seedling box 1 via a hinge 13, and the seedling inlet channel is located on one side of the baffle 12.

[0024] The baffle 12 is rotatably mounted inside the seedling inlet channel 3 via the hinge 13. When shrimp seedlings need to be poured in, the baffle 12 can be pushed upward to rotate. After the shrimp seedlings are poured in, the baffle 12 can cover the inside of the seedling inlet channel 3 under its own weight to prevent external light from entering the seedling box 1 through the seedling inlet channel 3.

[0025] Preferably, the light adjustment mechanism further includes a bearing 14 and a rotating shaft 15. The bearing 14 is mounted on a mounting plate 7 away from the rotating motor 9, and the rotating shaft 15 is mounted on the end of the roller 8 away from the rotating motor 9 and connected to the bearing 14.

[0026] When the drum 8 rotates, one end is driven by the rotary motor 9, and the other end of the shaft 15 can rotate under the support of the bearing 14.

[0027] Preferably, it also includes a semiconductor cooling chip 16, which is disposed at the bottom of the seedling box 1.

[0028] In addition to adjusting the light, the water temperature inside the seedling box 1 can also be adjusted. The semiconductor cooling chip 16 can cool the inside of the seedling box 1, lowering the water temperature by one or two degrees. Without harming the shrimp larvae, the movement of the shrimp larvae is slowed down by lowering the water temperature.

[0029] Preferably, the light adjustment mechanism further includes a guide wheel 17, which is inclinedly disposed on the side wall of the seedling box 1, and the bottom surface of the fully transparent film 10 passes through the surface of the guide wheel 17.

[0030] The guide rollers 17 allow the fully transparent film 10 and the light-blocking film 11 to move smoothly over the light-transmitting plate 2.

[0031] Preferably, it also includes a cleaning mechanism, which includes an electric push rod 18, a moving plate 19, and a cleaning sponge 20. The electric push rod 18 is disposed on the inner side wall of the seedling box 1, and its output shaft is connected to the side wall of the moving plate 19. The cleaning sponge 20 is disposed on the top surface of the moving plate 19. The night vision camera 6 is located on the moving path of the cleaning sponge 20. The height of the seedling inlet channel 3 is lower than the height of the moving plate 19.

[0032] During multiple seedling placements, the aquaculture water may splash onto the bottom of the night vision camera 6. At this time, the electric push rod 18 can be activated, which can drive the moving plate 19 to move, allowing the cleaning sponge 20 to move past the bottom of the night vision camera 6. Thus, the cleaning sponge 20 can clean the bottom of the night vision camera 6, ensuring that the night vision camera 6 can capture clear images.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
