Description

Technical Field

[0001] This utility model relates to the field of aquatic seedling counting technology, and in particular to an aquatic seedling counting device that improves reliability. Background Technology

[0002] Accurately counting the number of aquatic seedlings such as fish and shrimp is crucial for quality control in aquaculture and for the economic benefits of farmers and businesses. For valuable seedlings, the traditional method is manual counting. This method is not only costly but also prone to errors due to unintentional or intentional mistakes by workers. To ensure accuracy, dedicated supervisory positions are needed, but this is both labor-intensive and difficult to guarantee objectivity. For fish of lower economic value, a sampling method is typically used. A certain weight (e.g., one pound or half a pound) is randomly selected from the seedlings to be counted and manually counted, then used as a baseline to estimate the total number. However, this method still relies on manual counting, and sampling and counting errors can affect the accuracy of the final result.

[0003] With advancements in image recognition technology, novel counting methods and technologies based on image recognition have emerged in the market, aiming to more accurately and fairly count the number of aquatic seedlings. For example, a Chinese invention patent with publication number CN118485096A proposes a low-complexity, high-throughput online general-purpose fish fry counting method and device, which performs quantity counting by capturing image information of fish fry. However, in actual operation, water droplets splashing and adhering to the camera during image acquisition can cause severe image distortion, thus affecting the stability and accuracy of the counting. Therefore, technologies to solve the problem of water droplet interference in the camera area are particularly important for improving the performance of such systems. Utility Model Content

[0004] In view of the above-mentioned prior art, the present invention provides an aquatic seedling counting device that improves reliability, effectively preventing water droplets from splashing and adhering to the camera, thereby improving the reliability of aquatic seedling counting.

[0005] To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows:

[0006] A reliable aquatic seedling counting device includes an image acquisition device and a seedling channel. The image acquisition device is used to acquire image information on the seedling channel. It also includes a blowing device. An air duct is provided between the image acquisition device and the seedling channel. The airflow in the air duct is driven by the blowing device to flow in a direction away from the image acquisition device.

[0007] Furthermore, the blowing device includes a pump body and a pipe, with the air outlet of the pipe located on the side of the image acquisition device, and the pipe connected to the pump body.

[0008] Furthermore, the image acquisition device is a camera, the cylindrical surface of the inner cavity of the pipe is tangent to or intersects the lens surface of the camera, and the central axis of the pipe coincides with the central axis of the camera.

[0009] Furthermore, the pipe includes a tapered section and a cylindrical section, the cylindrical section being located on the side of the image acquisition device, the cylindrical section being connected to the smaller end of the tapered section, and the larger end of the tapered section being connected to the pump body.

[0010] Furthermore, it also includes a frame, on which the image acquisition device and the seedling channel are detachably mounted.

[0011] Furthermore, the seedling channel is made of a light-transmitting material as a track, and a supplementary light is provided at the bottom of the seedling channel. The supplementary light is a shadowless lamp, and the shadowless lamp is detachably connected to the track.

[0012] Furthermore, the frame is detachably equipped with a host module, which is connected to the camera signal.

[0013] Furthermore, the host module includes a processor, a touch display screen, a power supply, and a data interface. The touch display screen, power supply, and data interface are signal-connected to the processor, and the processor is signal-connected to the camera.

[0014] Furthermore, the frame is detachably equipped with a power module, which is electrically connected to the host module.

[0015] Furthermore, it also includes a seedling funnel, which is detachably connected to the frame.

[0016] Furthermore, the frame has a sealing plate on its side, and the sealing plates located at the front and rear have through holes.

[0017] The beneficial effects of this invention are as follows: By setting up an air duct between the image acquisition device and the seedling channel, and using a blower to guide the airflow away from the direction of the image acquisition device, it effectively prevents upward-splashing water droplets from adhering to the camera, avoiding the problem of unstable counting caused by image distortion. By reducing image acquisition errors caused by water droplets, not only is the accuracy of a single count improved, but the reliability of the entire counting process is also enhanced, enabling the system to operate stably under a wider range of environmental conditions. With the above design, there is no need to establish a dedicated supervisory position to ensure the accuracy of manual counting, simplifying the operation process and reducing labor costs and management complexity.

[0026] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the utility model.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element.

[0028] Please refer to the attached document. Figures 1-6 This application provides a reliable aquatic seedling counting device, including an image acquisition device 1 and a seedling channel 2. The image acquisition device 1 is used to acquire image information on the seedling channel 2. Preferably, the image acquisition device 1 is a camera. It also includes a blower device 3. An air duct 4 is provided between the image acquisition device 1 and the seedling channel 2. The air duct 4 refers to an area where air can circulate; this area can be open or surrounded by other entities. The airflow within the air duct 4 is driven by the blower device 3 to flow in a direction away from the image acquisition device 1. Aquatic seedlings are placed on the seedling channel 2. As the seedlings move along the seedling channel 2, the image acquisition device 1 acquires images, and the images are analyzed to count the aquatic seedlings. Preferably, the image acquisition device 1 is installed above the seedling channel 2. A duct 4 is provided between the seedling channel 2 and the image acquisition device 1. The duct 4 is connected to the air passage of the blowing device 3. When the blowing device 3 blows air into the duct 4, it causes the airflow within the duct 4 to move in a direction deviating from the image acquisition device 1. For example, the airflow moves to the left / right, or to the lower left / lower right, etc. That is, the airflow direction can be perpendicular to the direction of the image acquisition device 1, or it can form a certain angle with the direction perpendicular to the direction of the image acquisition device 1, causing the airflow to flow downwards. Due to the movement of the airflow, the upward splashing water receives a first thrust perpendicular to the direction of the image acquisition device 1 and / or a second thrust with the same force as the direction of the image acquisition device 1, thereby effectively preventing water from splashing onto the image acquisition device 1 and improving the stability of the counting.

[0029] Specifically, the blowing device 3 includes a pump body 5 and a pipe 6. The air outlet of the pipe 6 is located on the side of the image acquisition device 1, and the pipe 6 is connected to the pump body 5. The pump body 5 drives the gas to be discharged from the pipe 6. The gas discharged from the pipe 6 blows directly below the image acquisition device. The flow of gas from the pipe 6 is more concentrated, which can effectively blow away splashed liquid from the image acquisition device, keep the image acquisition device clean, and improve the stability of image acquisition.

[0030] Preferably, the image acquisition device 1 is a camera, the cylindrical surface of the inner cavity of the pipe 6 is tangent to or intersects the lens surface of the camera, and the central axis of the pipe 6 coincides with the central axis of the camera. Preferably, the horizontal distance between the end of the air outlet of the pipe 6 and the camera is 1-3 cm, which allows the airflow to more effectively blow away the splashed liquid.

[0031] Specifically, the pipe 6 includes a conical section 7 and a cylindrical section 8. The cylindrical section 8 is located on the side of the image acquisition device. The cylindrical section 8 is connected to the end of the conical section 7 with a smaller cross-section, and the end of the conical section 7 with a larger cross-section is connected to the pump body 5. The gas discharged through the pump body 5 flows from the conical section 7 to the cylindrical section 8, and then blows towards the bottom of the image acquisition device. During the gas flow, the cross-section of the flow channel it passes through decreases, thereby increasing the flow velocity and facilitating the blowing of splashed liquid away from the image acquisition device 1.

[0032] Specifically, it also includes a frame 9, on which the image acquisition device 1 and the seedling channel 2 are detachably mounted, for example, by bolt connection or snap-fit ​​connection. The frame 9, as a stable supporting component, can stably support and fix the seedling channel 2 and the image acquisition device 1.

[0033] Specifically, the seedling channel 2 is a track made of a light-transmitting material, and a supplementary light 10 is installed at the bottom of the seedling channel 2. The supplementary light 10 is a shadowless lamp, and the shadowless lamp is detachably connected to the track, such as by bolts or clips. The light-transmitting material can be made of polypropylene, for example, using PP board to make the seedling channel 2. The supplementary light 10 can compensate for insufficient light intensity, and the shadowless lamp can eliminate brightness differences and ghosting caused by the supplementary lighting process, improving the stability of image acquisition and counting.

[0034] Specifically, the frame 9 has a detachable host module 11, which is connected to the camera signal. The host module 11 includes a processor 12, a touchscreen display 13, and a power and data interface 15. The touchscreen display 13, power and data interface 15 are connected to the processor 12, which in turn is connected to the camera signal. The detachable installation of the host module 11 on the frame 9 facilitates equipment assembly and maintenance. The detachable method can be bolt connection, snap-fit ​​connection, etc. Multiple installation positions can be provided on the frame 9. The host module 11 of this invention is designed independently, and the integrated touchscreen display 13 serves as the display component, allowing for flexible installation and placement. To achieve the best viewing angle, it can be placed and adjusted at multiple angles and positions.

[0035] Specifically, the frame 9 is detachably equipped with a power module 16, which is electrically connected to the host module 11. The step-down circuit within the power module 16 reduces the input 220V power supply to a safe voltage of 36V or less before supplying it to the host module 11 via an aviation connector. It can also supply power to other modules, such as the supplementary lighting 10 and the blower 3. Preferably, each electrical module may use low-voltage power supply to improve its safety. Preferably, the entire step-down circuit is installed in a sealed junction box, making the waterproof design and heat dissipation design more reasonable. This effectively avoids the risk of leakage and short circuits caused by water vapor intrusion, significantly improving the insulation effect of the entire power system and effectively enhancing electrical safety.

[0036] Specifically, it also includes a seedling funnel 17, which is detachably connected to the frame 9, such as by bolts or snap-fit ​​connections. The bottom of the seedling funnel 17 has an opening located above the seedling channel 2. Seedlings in the seedling funnel 17 can slowly fall into the seedling channel 2 through the opening and slide slowly diagonally downwards along the channel. Because the seedling funnel 17 is connected to the frame 9, the funnel can be adjusted and replaced according to actual conditions. For example, if the seedlings require stress reduction, a water-holding funnel can be used, which reduces stress on the seedlings but is relatively slower. If efficiency is required, an open-mouthed funnel can be used, improving counting efficiency. Secondly, the funnel-shaped inlet allows fish to be stored in the container and descend the track in an orderly manner, preventing them from sticking together densely and improving counting accuracy.

[0037] Specifically, the frame 9 has a sealing plate 18 on its side, and the sealing plate 18 located at the front and rear has through holes 19. The through holes 19 allow observation of the interior and also facilitate the expulsion of moisture, thus improving waterproof performance.

[0038] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. The protection scope of this utility model should be determined by the protection scope of the stated claims.
