Description

Technical Field

[0001] This invention relates to the field of aquaculture technology, and in particular to a method and device for detecting shrimp mortality. Background Technology

[0002] Shrimp sudden mortality is a unique phenomenon that occurs in the later stages of shrimp farming. It typically manifests as the sudden, unannounced death of a small number of shrimp, or the discovery of a small number of dead individuals in the farming environment. Shrimp are mid- to bottom-dwelling aquatic animals, and due to the stealthy nature of their sudden mortality, it is usually not discovered until the dead shrimp have been submerged in water for an extended period and their density has decreased, causing water pollution. Therefore, by the time sudden mortality is discovered, a significant number of shrimp in the farming environment have already died, resulting in substantial economic losses for shrimp farmers.

[0003] Shrimp mortality disease frequently occurs in: ① the middle and late stages of farming, generally after 60 days of farming; ② high-temperature periods, when the air temperature is above 30℃ and the water temperature reaches above 28℃ (the peak period of outbreaks is from June to November in the annual cycle and from 12:00 to 14:00 in the daily cycle); ③ during the molting period of shrimp.

[0004] Therefore, during the aquaculture process, shrimp need to be harvested regularly by hand, which greatly increases the labor intensity of the personnel. A small number of shrimp are harvested using equipment, but even after being harvested by equipment, manual judgment is still required on site, which is not convenient overall. Summary of the Invention

[0005] In view of the problems existing in the prior art, the present invention is proposed.

[0006] Therefore, the purpose of this invention is to provide a method for detecting shrimp dying suddenly.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a method for detecting shrimp mortality, comprising the following steps,

[0008] First, shrimp are scooped from the pond using fishing equipment. Then, image signals are acquired by shrimp image acquisition. The color and activity level of the shrimp are then transmitted to the central processing unit's shrimp recognition system. The acquired shrimp video is analyzed and the recognition results are sent to the mobile phone.

[0009] As a preferred embodiment of the shrimp death detection method of the present invention, the result of the shrimp identification system is determined by a central processing unit;

[0010] If the shrimp identification result is weak activity, a warning message will be sent to the mobile device;

[0011] If the recognition result is normal, the shrimp's activity data and growth status information will be sent to the mobile phone.

[0040] Example 1

[0041] Reference Figures 1 to 7 This is the first embodiment of the present invention, which provides a method for detecting shrimp sudden death, including the following steps:

[0042] First, shrimp are scooped from the pond using fishing equipment. Then, image signals are acquired by shrimp image acquisition. The color and activity level of the shrimp are then transmitted to the central processing unit's shrimp recognition system.

[0047] Example 2

[0048] Reference Figures 1-5 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a detection device for implementing the shrimp mortality detection method. The detection device includes...

[0049] The support mechanism 100 includes a counterweight 101 placed on the ground 1, a support frame 102 fixedly connected to the top of the counterweight 101, and a bracket 103 fixedly connected to the outside of the support frame 102. One end of the support frame 102 is fixedly connected to a mounting frame 104. An adjustment component 105 is provided at the bottom of the inside of the mounting frame 104. An auxiliary component 106 is adapted to be installed on the outside of the mounting frame 104. A drive component 107 is provided at the top of the inside of the mounting frame 104.

[0050] Specifically, the adjustment component 105 includes a telescopic rod 105a that is slidably connected to the bottom of the mounting bracket 104, a top plate 105b that is fixedly connected to the top of the telescopic rod 105a, and a sealing component 105c that is provided at the bottom of the outer side of the telescopic rod 105a. A collection component 105d is provided inside the telescopic rod 105a.

[0051] The top plate 105b is slidably connected inside the mounting bracket 104.

[0052] Furthermore, the sealing assembly 105c includes a guide rod 105c-1 fixedly connected to the outside of the telescopic rod 105a, an anti-detachment block 105c-2 fixedly connected to one end of the guide rod 105c-1, and a first spring 105c-3 sleeved on the outside of the guide rod 105c-1.

[0053] Preferably, the sealing assembly 105c further includes a slide plate 105c-4 slidably connected to the outside of the guide rod 105c-1, a wedge block 105c-5 fixedly connected to the top of the slide plate 105c-4, and a sealing plate 105c-6 fixedly connected to the bottom of the slide plate 105c-4, with a scraper 105c-7 fixedly connected to the top of the sealing plate 105c-6.

[0054] One end of the first spring 105c-3 is connected to the anti-detachment block 105c-2, and the other end of the first spring 105c-3 is connected to the slide plate 105c-4.

[0055] It should be noted that the auxiliary component 106 includes a bottom block 106a that is bolted to the bottom of the mounting bracket 104, cavities 106b formed on both sides of the bottom block 106a, and guide grooves 106c formed inside the cavities 106b.

[0056] Among them, the guide groove 106c has a triangular design.

[0057] Preferably, the drive component 107 includes a motor 107a adapted to be installed inside the mounting bracket 104, and a threaded rod 107b fixedly connected to the output end of the motor 107a, the threaded rod 107b being threadedly connected to the telescopic rod 105a.

[0058] Among them, the motor 107a, the lighting lamp 105d-3, and the camera 105d-4 are electrically connected to the host computer.

[0059] First, feed is placed inside the fishing platform 201. Then, the motor 107a is started by the host computer. The motor 107a can drive the threaded rod 107b to rotate. Through the cooperation of the threaded rod 107b and the telescopic rod 105a, the telescopic rod 105a can be driven to slide upward until the fishing platform 201 is completely pulled out of the pond 2.

[0060] When the telescopic rod 105a slides to the bottom of the inclined block 105c-5, the fishing platform 201 has been pulled up from the pond 2. As the telescopic rod 105a continues to slide upward, the inclined block 105c-5 will slide under the guidance of the bottom of the bottom block 106a, simultaneously driving the sliding plate 105c-4 to slide outside the guide rod 105c-1 and compress the first spring 105c-3. When the inclined block 105c-5 slides to the outside of the guide groove 106c, the elasticity of the first spring 105c-3 will cause the sliding plate 105c-4 and the inclined block 105c-5 to return to their original positions. Furthermore, with the telescopic rod 105a continuing to slide upward and in conjunction with the triangular design of the guide groove 106c, the inclined block 105c-5 will continuously unfold outward and return to its original position until the inclined block 105c-5 slides above multiple sets of guide grooves 106c. At this point, the inclined block 105c-5 will always be in an unfolded state.

[0061] When the inclined block 105c-5 is always in the extended state, the sealing plate 105c-6 can be fully opened, ensuring that the subsequent camera 105d-4 can collect images and videos of the shrimp normally. When the telescopic rod 105a is in the pond 2, the sealing plate 105c-6 is in the closed state, which ensures that the glass 105d-5 cannot come into contact with the water in the pond 2.

[0062] Since Pond 2 is aquaculture water, it contains many impurities. If the glass 105d-5 is in contact with the water for a long time, impurities and dirt will adhere to its surface, preventing the equipment from performing normal collection work. This equipment, through its sealed design, ensures that the glass 105d-5 can be separated from the water when it is in Pond 2. At the same time, when the equipment is lifted to perform collection work, the sealing plate 105c-6 can be automatically deployed to ensure the normal operation of the collection work. This ensures continuous use, increases the service life of the equipment, and reduces subsequent maintenance costs.

[0063] As the inclined block 105c-5 continuously unfolds and resets, it can preferentially drive the scraper 105c-7 at the top of the sealing plate 105c-6 to scrape and clean the surface of the glass 105d-5. Even if water stains or debris adhere to the surface of the glass 105d-5 during the unfolding process of the sealing plate 105c-6, secondary cleaning can be achieved to ensure the cleanliness of the glass 105d-5 and allow the collection work to proceed normally.

[0064] In summary, the equipment adopts a sealed design, which ensures that the glass 105d-5 can be separated from the water when it is in pond 2. At the same time, when the equipment is lifted for collection work, the sealing plate 105c-6 can be automatically deployed to ensure the normal operation of the collection work. This ensures continuous use, improves the service life of the equipment, and reduces subsequent maintenance costs. In addition, the deployment of the sealing plate 105c-6 can also achieve secondary cleaning of the surface of the glass 105d-5, allowing the collection work to proceed normally.

[0065] Example 3

[0066] Reference Figure 6 and Figure 7 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a data acquisition component 105d, including a slide rod 105d-1 slidably connected inside the mounting frame 104, a mounting frame 105d-2 fixedly connected to the bottom end of the slide rod 105d-1, and a lighting lamp 105d-3 installed inside the bottom end of the mounting frame 105d-2. A camera 105d-4 is installed inside the bottom end of the mounting frame 105d-2, and a glass 105d-5 is installed at the bottom end of the mounting frame 105d-2. A second spring 105d-6 is sleeved on the outside of the slide rod 105d-1.

[0067] One end of the second spring 105d-6 is connected to the mounting bracket 104, and the other end of the second spring 105d-6 is connected to the mounting frame 105d-2.

[0068] Specifically, it also includes,

[0069] The fishing mechanism 200 includes a fishing platform 201 located directly below the telescopic rod 105a, a fishing net 202 installed at the bottom of the fishing platform 201, and a sling lock 203 fixedly connected to the top of the fishing platform 201. The other end of the sling lock 203 is fixedly connected to the sealing plate 105c-6.

[0070] When the inclined block 105c-5 slides above the guide groove 106c, causing the sealing plate 105c-6 to unfold, the telescopic rod 105a continues to slide upward, which causes the slide rod 105d-1 to contact the bottom end of the threaded rod 107b. As the telescopic rod 105a slides up and down, the slide rod 105d-1 is squeezed by the threaded rod 107b, causing the mounting frame 105d-2 at the bottom of the slide rod 105d-1 to extend from the bottom end of the telescopic rod 105a. This brings the lighting lamp 105d-3, the camera 105d-4, and the fishing platform 201 closer, ensuring that the camera 105d-4 can collect data more clearly and accurately during the process.

[0071] As the inclined block 105c-5 continuously expands outward and resets, the sealing plate 105c-6 will cause the hanging lock 203 to move back and forth continuously, causing the fishing platform 201 to shake and vibrate. The shaking and vibration of the fishing platform 201 can not only quickly shake off the water brought up by the fishing platform 201 to reduce the overall weight of the equipment, but also shake the shrimp inside the fishing platform 201 to achieve flatness and improve the shrimp harvesting effect.

[0072] In addition, the shaking and vibration of the fishing platform 201 can also startle the shrimp, causing them to move inside the platform 201, thereby quickly identifying the shrimp's activity and making an accurate judgment on their condition.
