[0002] In crayfish farming, due to the strong climbing ability and digging ability of crayfish, traditional farming pond fences are difficult to effectively prevent crayfish from escaping, resulting in farming losses. Therefore, a farming fence with a simple structure, low cost, and effective prevention of crayfish escape is needed.

[0003] Chinese Patent with publication number CN218635058U discloses a fence for crayfish farming that prevents escape. By setting fixed pins, a middle rotating cylinder, and an outer rotating cylinder, the connection between the fence panels is rotatable, making the installation and removal of the fence panels more convenient and reusable. At the same time, a spiral cone is used to make the fixed pins more firmly fixed on the ground, which can better fix the fence panels and increase the stability of the fence panels. In this patent, the fence panels adopt an inwardly concave < - shaped fixing structure, which results in low flexibility of the fence panels. Crayfish will look for hidden places to rest during the day, such as under stones, in waterweeds, or in self - dug caves, and use these places to adjust their humidity and temperature. The open fence panels are not conducive to crayfish hiding. Summary of the Utility Model

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0020] Combination Figures 1 - 3 The utility model of the crayfish breeding fence for preventing escape comprises an end limit plate 1, which is composed of two flat plates vertically connected. A fixing nail 11 is arranged at the lower end of the end limit plate 1, and the fixing nail 11 is inserted into the soil to fix the end limit plate 1. At the same time, the lower end of the end limit plate 1 is also inserted into the soil following the fixing nail 11, so as to improve the firmness of the end limit plate 1 when in use. A mounting hole 12 is opened on the end limit plate 1, and a fence assembly 2 is inserted into the mounting hole 12. The fence assembly 2 can rotate in the mounting hole 12 to change the angle of the fence assembly 2.

[0021] The railing assembly 2 includes a fence body 21 and an anti-climbing plate 22. The upper end of the fence body 21 is hinged to the lower end of the anti-climbing plate 22. A first axle seat 221 is provided at the lower end of the anti-climbing plate 22. A plug rod 222 is fixedly connected to the first axle seat 221. A second axle seat 211 is provided at the upper end of the fence body 21. An axle hole 2111 is opened on the second axle seat 211, and the axle hole 2111 is sleeved with the plug rod 222. The first axle seat 221 and the second axle seat 211 are both discontinuous axle fixing seats. The first axle seat 221 and the second axle seat 211 are cross-arranged, and the fence body 21 and the anti-climbing plate 22 can rotate relative to each other.

[0022] The first shaft seat 221 is extended from both ends of the plug rod 222, and the two ends of the plug rod 222 are provided with external threads, and the plug rod 222 is meshed with a locking nut 223 through the external threads. The plug rod 222 passes through the mounting hole 12, and the locking nut 223 meshed on the plug rod 222 is tightened to increase the friction between the fence body 21, the anti-climbing plate 22 and the end limit plate 1. After tightening, the angle of the fence body 21 and the anti-climbing plate 22 is fixed and cannot rotate. After loosening the locking nut 223, the fence body 21 cannot move under the cover of the soil, but the anti-climbing plate 22 can change the inclination angle of the anti-climbing plate 22 by rotating the angle of the plug rod 222. The climbing board 22 is rotated to the same inclination angle as the fence main body 21, and the fence main body 21 is extended. The anti-climbing board 22 can also be rotated to incline toward the inside of the breeding pond, forming a closing structure at the upper end of the breeding pond. The anti-climbing board 22 itself does not contact the water surface. The anti-climbing board 22 tilted inward can also prevent crayfish from crossing the fence main body 21. At the same time, the anti-climbing board 22 can block the sunlight and provide a hidden resting area for crayfish. At the same time, the movable anti-climbing board 22 can also facilitate the work needs of the breeders. The end limit plate 1 is set to a certain width. When the fence main body 21 and the anti-climbing board 22 rotate, the end is always kept in contact with the end limit plate 1.

[0023] To improve air permeability and increase the firmness of the fence main body 21 in contact with the soil, ventilation holes 213 are provided on the fence main body 21. After the fence main body 21 is inserted into the soil, the fence main body 21 is inclined in the soil, and the soil itself presses on the fence main body 21, enhancing the stability of the fence main body 21 and the safety of preventing crayfish from escaping. A slope 212 is provided at the lower end of the fence main body 21, and the slope 212 facilitates the insertion of the fence main body 21 into the soil.

[0024] Working process: Install the fence main body 21 and the anti-climbing board 22 on the end limiting plate 1, control the angles of the fence main body 21 and the anti-climbing board 22, tighten the locking nut 223, insert the end limiting plate 1 together with the fence main body 21 into the soil. During use, the fence main body 21 forms a sealed area at the edge of the aquaculture pond to prevent crayfish from escaping. The angle of the installed fence main body 21 is fixed. According to the time of use, during the day, adjust the anti-climbing board 22 to incline towards the center of the aquaculture pond to form a shaded area at the edge of the aquaculture pond for crayfish to rest. At night, adjust the anti-climbing board 22 to be vertical or incline towards the outside of the aquaculture pond to prevent crayfish from escaping.
