Embodiment 1

[0014] This embodiment proposes a hollow crab-preventing plastic wall that is easy to install and low in cost.

[0015] Such as figure 1 As shown, the hollow crab escape prevention plastic wall of this embodiment includes a frame, a metal wire and a flexible plastic tube 1 with openings at both ends. The frame is composed of a bottom plate 3 and vertical frames fixed at both ends of the bottom plate 3. The frame is composed of fixed vertical columns 4 on both sides and shaped vertical columns 5 in the middle. The fixed vertical columns 4 pass through the bottom plate 3 and are fixedly connected with the bottom plate 3. The bottom ends of the fixed vertical columns 4 are tapered; the shaped vertical columns 5 The height is lower than the height of the fixed vertical column 4, the top and bottom of the fixed vertical column 4 are provided with a fixed ring, and the top of the modeling vertical column 5 is provided with a fixed ring; the wire includes a fixed wire 6 and a molding...

Abstract

The invention provides a hollow crab anti-escape plastic wall with convenient mounting and low cost. The hollow crab anti-escape plastic wall comprises a frame, metal wires and a flexible plastic cylinder with openings at two ends, wherein the frame consists of a bottom plate and a vertical frame fixed at two ends of the bottom plate; the vertical frame consists of fixing vertical columns on two sides and a modelling vertical column in the middle; the height of the modelling vertical column is lower than that of the fixing vertical columns; fixing rings are formed in the top and lower parts ofthe fixing vertical columns; a fixing ring is formed in the top of the modelling vertical column; the metal wires comprise fixing metal wires and a modelling metal wire; the fixing metal wires penetrate through the plastic cylinder to spread the plastic cylinder; both ends of the fixing metal wires penetrate through the fixing rings of the fixing vertical columns and are fixedly connected with the fixing vertical columns; the modelling metal wire is positioned above the plastic cylinder and presses the plastic cylinder downwards to form an anti-escape groove in the top of the plastic cylinder; two ends of the modelling metal wire penetrate through the fixing rings of the modelling vertical column and are fixedly connected with the modelling vertical column.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to anti-escape facilities used in crab cultivation. Background technique [0002] River crabs have a strong ability to escape, and the choice of anti-escape facilities directly affects the return rate of crabs. The current common anti-escape facilities for crabs are made of cement sheets. Prefabricate cement sheets with a length of 1 meter, a width of 0.8-1.0 meters, and a thickness of 2-3 cm with reinforced concrete, and lay them along the surrounding fields. The cement boards are 30-40 cm into the ground and 50-60 cm above the ground. Smooth it with cement, keep the inner wall as smooth as possible, tamp the wall foundation, and press an iron sheet with a width of 20 to 30 cm on the top of the cement sheet to prevent river crabs from escaping. The investment of the above-mentioned crab escape prevention facilities is large, which is difficult for many farmers to ...
