Description

Technical Field

[0001] This utility model relates to the field of shrimp farming, and in particular to a disease prevention and control device for Litopenaeus vannamei farming. Background Technology

[0002] Litopenaeus vannamei, also known as Pacific white shrimp or white-legged shrimp, originated from the eastern Pacific coast and is one of the three most farmed shrimp species in the world. In recent years, diseases of Litopenaeus vannamei have occurred frequently, some of which are even devastating. When using conventional equipment to isolate diseased shrimp, the feces of the diseased shrimp contain viruses, and excessive accumulation can pollute the water, which is detrimental to the survival of the shrimp. It is also difficult to separate the feces from the diseased shrimp, thus affecting the effectiveness of the equipment.

[0003] To address the aforementioned issues, existing patent (CN221554408U) discloses a biological disease isolation device for Litopenaeus vannamei, comprising a first threaded rod, a movable plate, a synchronous wheel, a synchronous belt, a fixed cylinder, a fixed shaft, a coil spring, a partition net, and a housing. Rotating one of the first threaded rods causes the movable plate to move. Synchronous wheels are fixedly connected to the outer sides of one end of both first threaded rods, and synchronous belts are tensioned around the outer sides of the two synchronous wheels, causing the two first threaded rods to rotate synchronously. The rotation of the first threaded rods drives the two movable plates to move, which in turn drives the fixed cylinder to move. The fixed cylinder, in turn, drives the fixed shaft to move, which in turn drives the coil spring and the partition net to move. This allows for adjustment of the partition net's distance. When the fixed cylinder moves, it drives the fixed shaft to move, causing the partition net and coil spring to unwind, thus lengthening the partition net to accommodate different housing sizes. This facilitates adjustment of the partition net's tilt angle, separates the excrement of diseased shrimp from the shrimp body, and removes the excrement, thereby improving the device's effectiveness.

[0004] However, in the aforementioned existing technologies, after the excrement of diseased shrimp is separated from the shrimp body, it is time-consuming and laborious to clean the excrement, making it inconvenient to remove the excrement from inside the tank, which can easily affect the shrimp farming environment. Utility Model Content

[0005] The purpose of this utility model is to provide a disease prevention and control device for Litopenaeus vannamei farming, which solves the technical problem in the prior art that after the excrement of diseased shrimp is separated from the shrimp body, it is time-consuming and laborious to remove the excrement from the inside of the tank, which can easily affect the shrimp farming environment.

[0006] To achieve the above objectives, this utility model employs a disease prevention and control device for Litopenaeus vannamei aquaculture, comprising a housing and structural components. The structural components include a grid, a water tank, a pump, a filter box, a fine filter, an activated carbon filter, a top block, a feeding box, an adjusting component, and an installation component. The grid is detachably connected to the housing. The water tank is connected to the housing via a pipe. The output end of the pump is connected to the housing via a pipe, and the input end of the pump is connected to the water tank via a pipe. The installation component is connected to the filter box. The top block is detachably connected to the filter box and to the installation component. The filter box is thermally fixed to the top block and detachably connected to the water tank. The fine filter is fixedly installed on the top block near the filter box. The activated carbon filter is fixedly installed on the top block near the fine filter. The feeding box is detachably connected to the housing, and the adjusting component is connected to the feeding box.

[0007] The mounting component includes a frame, a stop block, and a driving component. The frame is slidably connected to the water tank and is located on the side of the water tank away from the top block. The driving component is connected to the frame, and the stop block is slidably connected to the frame and connected to the driving component.

[0008] The driving component includes a driving rod and a driving block. The driving rod is rotatably connected to the frame and threadedly connected to the abutment block. The driving block is fixedly connected to the driving rod and is located on the side of the driving rod away from the abutment block.

[0009] The adjusting component includes an adjusting block and a moving part. The adjusting block is slidably connected to the feeding box and is located on the side of the feeding box away from the box body. The moving part is connected to the box body and to the adjusting block.

[0010] The moving component includes a moving rod and a moving motor. The moving rod is rotatably connected to the feeding box and threadedly connected to the adjusting block. The moving motor is fixedly connected to the feeding box, and the output shaft of the moving motor is connected to the moving rod.

[0011] This utility model discloses a disease prevention and control device for Litopenaeus vannamei (whiteleg shrimp) farming. Rotating the drive block drives the drive rod to rotate on the frame. The drive rod engages with the stop block, causing the stop block to move and fix the top block on the water tank. The top block drives the filter box, the fine filter screen, and the activated carbon filter screen to be installed on the water tank, pushing the grid screen to move on the tank body, mechanically separating diseased shrimp from their excrement. Subsequently, the pump body operates, guiding the excrement into the water tank. The filter box filters large excrement particles, the fine filter screen filters small excrement particles, and the activated carbon filter screen filters the water. The filtered water re-enters the tank body, facilitating the removal of excrement from the tank body and thus avoiding any impact on the shrimp farming environment. Attached Figure Description

The outer side of the grid 102 is detachably connected to the inner side of the box body 101. The water... The interior of tank 103 is hollow. An installation port is designed at the top of tank 103, and movable grooves are designed at both the front and rear ends of tank 103. The right end of tank 103 is connected to the lower left side of tank body 101 via a pipe. A rubber pad is designed on the upper outer side of the vertical end of top block 108. The mounting component installs the outer side of the vertical end of top block 108 onto the installation port of tank 103. Filter box 105 is located on the bottom right side of top block 108. Fine filter screen 106 is located at the bottom center of top block 108, and activated carbon filter screen 107 is located on the bottom left side of top block 108.

The filter box 105 filters large excrement particles, the fine filter 106 filters small excrement particles, and the activated carbon filter 107 filters the water. The filtered water is then reintroduced into the box 101, facilitating the removal of excrement from the inside of the box 101 and thus avoiding any impact on the shrimp farming environment.
