Description

Technical Field

[0001] This utility model relates to the technical field of separation devices, specifically a separation device for mixed fish farming in lotus ponds. Background Technology

[0002] Polyculture of fish (such as carp, crucian carp, and loach) in lotus ponds is a highly efficient ecological farming model. Fish loosen the soil, prey on pests, and their excrement serves as fertilizer, while lotus roots provide shade and habitat for the fish, creating a virtuous cycle. Without separation, fish (especially herbivorous fish) will nibble on the tender shoots, stems, leaves, and roots of the lotus roots, affecting their growth and yield. Furthermore, it is impossible to effectively protect the fish when fertilizing or applying pesticides.

[0003] In existing technologies, some use fixed cement or earthen embankments for separation. However, during operations such as lotus root harvesting and pond clearing, these fixed embankments severely hinder mechanical and manual operations, greatly impacting harvesting efficiency and preventing flexible adjustments to the size and shape of the partitions according to annual farming plans. To address these issues, a fish separation device for lotus root ponds is proposed. Utility Model Content

The multi-point burial method provides a solid foundation for the entire structure and prevents it from tipping over or shifting during use.

[0026] Please see Figure 1 The docking rings 201 on both sides of the frame 101 are staggered to facilitate the connection after the adjacent frames 101 are docked.

[0027] Please see Figure 2 and Figure 3 The snap-fit ​​component includes a handle 207 connected to the top of the insert rod 206. The top of the positioning post 202 is provided with an insertion groove 204 for vertical insertion of the handle 207. An arc-shaped strip 205 is provided on one side of the insertion groove 204. The handle 207 is provided with a mating interface 208 for insertion into the arc-shaped strip 205. The middle part of the positioning post 202 is provided with a through hole 203 communicating with the through hole on the mating ring 201. Align the mating rings 201 that are staggered on the side walls of two adjacent support frames. Insert the rod 206 through the through hole 203 and through multiple mating rings 201 to restrict the lateral movement of the mating rings 201. After the rod 206 is inserted, align the handle 207 with the insertion slot 204 and then rotate the handle 207. Rotating the handle 207 will engage the interface 208 with the arc strip 205 on the positioning post 202, making the connection convenient.

[0028] Please see Figure 5The bottom of the frame 101 is provided with a drain hole 106 that communicates with the horizontal groove 105. The drain hole 106 at the bottom of the frame allows some of the silt and fish feces and other debris at the bottom of the pond to be discharged when the water flows or when it is manually cleaned, preventing excessive accumulation at the bottom of the device. The frame 101 is provided with vertical grooves 107 on both sides. The top side of the vertical groove 107 is provided with an installation groove 108 for hanging the hanging plate 303. The bottom rod 302 of the protective net is placed into the horizontal groove 105 at the bottom of the frame, and the hanging plate 303 at the top of the protective net 3 is hung into the installation grooves 108 on both sides of the frame 101, thus completing the initial and rapid positioning and fixing of the protective net 3.

[0029] Please see Figure 7 The limiting structure 4 includes a limiting rod 401, an adjusting rod 402, a rotating block 403, and a positioning fork 404. The limiting rod 401 is placed in the vertical groove 107. The rotating block 403 is fixedly connected to the side of the two sets of limiting rods 401 that are close to each other. The rotating block 403 is rotatably connected to the adjusting rod 402. The ends of the two sets of adjusting rods 402 that are away from the rotating block 403 are rotatably connected. The bottom end of the positioning fork 404 is connected to the frame 101 through a positioning bolt 405. The top two ends of the positioning fork 404 are connected to the adjusting rod 402 through positioning bolts 405. The adjusting rod 402 is provided with a positioning screw hole 406 that cooperates with the positioning bolt 405. The bottom rod 302 is provided with a fixing hole 304 for the positioning bolt 405 to pass through. The positioning bolt 405 is threadedly connected to the frame 101. After the protective net 3 is initially fixed, the adjusting rod 402 is unfolded, and the limiting rod 401 is placed in the vertical groove 107. The two sets of adjusting rods 402 are unfolded and can be fixed with the positioning fork rod 404. The bottom end of the positioning fork rod 404 is fixed to the frame 101 by the positioning bolt 405, and the top end is fixed to the adjusting rod 402 by the positioning bolt 405.
