This utility model relates to the field of
aquaculture equipment technology and discloses a
marine aquaculture net fixing device, comprising a first mounting plate, a second mounting plate, a connecting block, an arc-shaped spring plate, a locking device, a connecting post, and a limiting hole. The arc-shaped spring plate is an open ring shape, connecting the two mounting plates through the connecting block. The elasticity allows the mounting plates to close and clamp the net, and facilitates the threading of ropes to connect other facilities. The two mounting plates are respectively provided with connecting posts and limiting holes on corresponding sides for accurate alignment, ensuring even force on the net and preventing displacement and damage. The locking device includes a base, a first connecting rod, a second connecting rod, a locking rod, and other components. These components work together to achieve quick locking and unlocking of the mounting plates. The collar guides and limits the locking rod, improving locking reliability. The
handle at the hinge is easy to operate, reducing labor intensity. The bent rod on the locking rod engages with the connecting
post insertion hole to form a stable connection, resisting
seawater impact, ensuring the mounting plates are tightly fixed, and preventing the net from loosening and slipping. It is suitable for complex
aquaculture environments.
