Description

Technical Field

[0001] This utility model relates to the field of aquaculture equipment technology and discloses an escape-prevention floating fence device for aquaculture. Background Technology

[0002] In aquaculture, fencing is a core component to prevent fish from escaping and to separate aquaculture areas. Traditional aquaculture fencing often uses fixed installation methods, where fishing nets or enclosure nets are secured between the bottom and the water surface using fixed stakes to form an enclosed aquaculture area. However, in natural aquaculture environments, water levels fluctuate due to factors such as rainfall, tides, and water changes. Traditional fixed fencing has a fixed height, which becomes insufficient when the water level rises, allowing fish to easily escape from the top. When the water level drops, gaps easily form between the bottom of the fencing and the bottom, or the netting may sag, again posing an escape risk. Furthermore, the complex method of fixing the netting in traditional fencing makes disassembly and reassembly cumbersome and inefficient when adjusting the fencing area or maintaining the netting. Utility Model Content

[0003] This invention addresses the technical problem of traditional fixed fences having a fixed height, which results in insufficient effective height when the water level rises, allowing aquatic organisms to easily escape from the top of the fence; and when the water level drops, gaps easily form between the bottom of the fence and the bottom, or the netting sags, posing the same risk of escape. The invention provides an escape-prevention floating fence device for aquaculture.

[0004] To achieve the above-mentioned technical effects, the technical solution adopted by this utility model is: a floating enclosure device for preventing escape in aquaculture, comprising four sets of symmetrically distributed fixed and floating unit combinations, each set of the fixed and floating unit combinations including: a fixed component fixed to the bottom of the water and a floating component floating on the water surface; an integral woven fishing net, connected to the four sets of fixed and floating components respectively through connecting components to form a closed aquaculture area; and the height of the woven fishing net is greater than the vertical distance between any set of fixed components and the corresponding floating component, for adapting to the dynamic adjustment of the water level adaptive component; the escape prevention mechanism: each set of the floating... A coil mounting base is installed on the moving part, and the inner wall of the coil mounting base is rotatably connected to the coil body, while the outer wall is fixedly connected to the drive motor; the wire end of the coil body is connected to the fixing ring on the corresponding fixing part; water level adaptive component: each set of the floating part is movably connected to a movable plate, and the movable plate is driven to move along the height direction of the floating part by an adjustment component; a water level monitoring sensor is provided on the movable plate for real-time monitoring of the current water level; control module: the drive motor and the water level monitoring sensor are electrically connected to the controller, and the coil body is automatically controlled to reel in and release the wire based on the water level monitoring signal, so that the effective height of the woven fishing net covers the range of water level changes in the aquaculture area.

[0005] As a preferred embodiment, the four sets of fixing components are symmetrically distributed in a rectangular or ring shape on the bottom of the water at the edge of the aquaculture area, and the corresponding four sets of floating components float on the water surface. After the woven fishing net is connected to the four sets of fixing components and floating components through the connecting components, a closed ring or rectangular aquaculture boundary is formed.

[0006] As a preferred embodiment, the connecting assembly includes: a fixing plate fixed to the fixing member and the floating member respectively, and a clamping plate slidably connected to the fixing member and the floating member respectively; a clamping screw threadedly connected to the fixing member and the floating member respectively, one end of the clamping screw being rotatably connected to the clamping plate, and the other end being screwed with a clamping nut.

[0007] As a preferred embodiment, the length of the woven fishing net is 1.2 to 1.5 times the maximum water level fluctuation range of the aquaculture area, ensuring that the net is always taut when the coil body is being wound up and down.

[0008] As a preferred embodiment, the controller integrates a wireless communication module for remotely transmitting water level monitoring data and fence status information to the aquaculture management terminal.

[0009] In a preferred embodiment, the floating component is provided with a waterproof protective shell, and the coil body and the drive motor are located inside the waterproof protective shell; In a preferred embodiment, an auxiliary roller is mounted on the floating component, and the surface of the auxiliary roller makes rolling contact with the wire of the coil body.

[0010] Compared with existing technologies, this utility model uses a water level monitoring sensor to monitor the water level in real time, and the controller automatically controls the drive motor to drive the coil body to reel in and out the wire, so that the effective height of the woven fishing net is adjusted synchronously with the water level changes. Regardless of whether the water level rises or falls, it can ensure that the net effectively covers the aquaculture area, solving the escape risk caused by water level fluctuations in traditional fences. Through the cooperation of the clamping screws and clamping nuts of the connecting components, the woven fishing net can be quickly fixed and disassembled with the fixed and floating components, making maintenance convenient. The four sets of fixed components can be distributed in a rectangular or ring shape to adapt to aquaculture areas of different shapes. The adjustment component can calibrate the installation height of the water level monitoring sensor to adapt to different initial water level environments. Attached Figure Description
