Description

Technical Field

[0001] This utility model relates to the field of aquaculture equipment technology, specifically to a marine aquaculture net fixing device. Background Technology

[0002] In modern aquaculture, netting, as a core component of aquaculture facilities, plays a vital role in isolating aquaculture areas and protecting farmed organisms. As aquaculture develops towards large-scale and intensive operations, and aquaculture areas expand, netting must withstand more complex marine environments, such as tides, waves, and currents. This places higher demands on the reliability and stability of netting fixing devices. Traditional aquaculture netting fixing devices often use bolt connections, clips, or rope binding. Bolt connections are prone to corrosion under long-term seawater immersion, leading to loosening or even breakage of the bolts and causing netting failure. While clip binding... Installation is relatively convenient, but uneven force on the buckles can easily cause localized wear on the netting, shortening its lifespan. Furthermore, the buckles may slip off under strong external impact. Rope binding methods suffer from insufficient fixing strength, making it difficult to withstand the impact of large waves and currents, which can easily lead to netting displacement or detachment. In addition, traditional fixing devices often require multiple tools during installation and disassembly, making the operation cumbersome and consuming a lot of manpower and time. The limitations of traditional devices are even more prominent in scenarios where frequent adjustments or replacements of the netting are needed. To solve the above problems, we have proposed a marine aquaculture net fixing device. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a marine aquaculture net fixing device, which solves the aforementioned problems.

[0004] To achieve the above-mentioned objectives, this utility model provides the following technical solution: a marine aquaculture net fixing device, comprising a first mounting plate and a second mounting plate, wherein a set of connecting blocks is respectively provided on one side of the first mounting plate and the second mounting plate, and an arc-shaped spring plate is provided on the side of the two sets of connecting blocks opposite to the first mounting plate and the second mounting plate; a set of locking devices is respectively provided inside the first mounting plate and the second mounting plate; and multiple sets of connecting posts and multiple sets of limiting holes are respectively provided on the corresponding side of the first mounting plate and the second mounting plate; further comprising:

[0005] The locking device forms a stable mechanical connection by having the bent rod on the locking rod engage with the insertion hole of the connecting post. In conjunction with the collar, the locking rod is guided and limited, which enhances the structural stability of the locking device. It can withstand the impact of seawater and ensure that the device can be used stably for a long time in complex aquaculture environments.

[0006] Preferably, the arc-shaped spring plate is an open ring, and a set of connecting blocks are fixedly installed at both ends of the opening. The two sets of connecting blocks are fixedly installed together with the first mounting plate and the second mounting plate on the side away from the arc-shaped spring plate, respectively. The first mounting plate and the second mounting plate are connected together by the arc-shaped spring plate and the two sets of connecting blocks.

[0007] Preferably, multiple sets of connecting posts are fixedly installed on one side of the first mounting plate and the second mounting plate, and limiting holes corresponding to the multiple sets of connecting posts are opened on the side of the first mounting plate and the second mounting plate near the multiple sets of connecting posts. The multiple sets of connecting posts in the first mounting plate correspond to the multiple sets of limiting holes in the second mounting plate, and the multiple sets of connecting posts in the second mounting plate correspond to the multiple sets of limiting holes in the first mounting plate. Multiple sets of insertion holes are provided in the middle of one side of the multiple sets of connecting posts.

[0008] Preferably, the locking device includes a base, a first connecting rod, a second connecting rod, and a locking rod. The base is fixedly installed on one side of the first mounting plate and the second mounting plate respectively. The top of the base opposite to the connecting column has a protrusion, and the first connecting rod is installed at the protrusion.

[0012] Compared with the prior art, this utility model provides a marine aquaculture net fixing device, which has the following beneficial effects:

[0013] 1. This marine aquaculture net fixing device differs from traditional devices that often use single buckles or bolts, which can lead to insecure fixing and uneven stress on the net, causing it to loosen or even break under seawater impact. This device utilizes the elastic properties of an arc-shaped spring plate to automatically close the first and second mounting plates, tightly clamping the net. Simultaneously, multiple sets of connecting posts and limiting holes are correspondingly set, ensuring precise alignment during installation and uniform stress on the net during fixing. This design not only improves installation efficiency but also effectively prevents net displacement and damage, greatly enhancing the reliability and stability of net fixing and ensuring the normal operation of marine aquaculture.

[0014] 2. This aquaculture net fixing device addresses the common problem that traditional aquaculture net fixing devices often require multiple tools for bolt tightening and buckle fixing, which is time-consuming, labor-intensive, and difficult to operate. This device innovatively incorporates a locking device and handle, greatly improving the user experience. Operators can easily engage the first link, second link, and locking rod by simply operating the handle, enabling rapid locking and unlocking of the mounting plate. The collar guides and limits the locking rod, ensuring the accuracy and reliability of the locking action. This design increases the force application area, making operation more effortless and comfortable, reducing labor intensity, and significantly improving work efficiency, especially in frequent operation scenarios. Compared to traditional devices, it greatly saves labor and time costs. Attached Figure Description

[0043] Instructions for use

[0044] The first mounting plate 1 and the second mounting plate 2 are connected by an arc-shaped spring plate 4 and a connecting block 3. The elasticity of the arc-shaped spring plate 4 causes the two mounting plates to close under force, initially clamping the mesh tightly. At the same time, multiple sets of connecting posts 5 and limiting holes 6 are correspondingly set on opposite sides of the first mounting plate 1 and the second mounting plate 2. During installation, the connecting posts 5 are inserted into the limiting holes 6 to ensure accurate alignment of the two mounting plates. This not only improves installation efficiency but also ensures that the mesh is subjected to uniform force during clamping, preventing displacement and damage. The locking device 8 is installed inside the first mounting plate 1 and the second mounting plate 2 and consists of a base 9, a first connecting rod 10, a second connecting rod 11, and a locking rod 12. During operation, the handle 14 drives the first connecting rod 10 and the second connecting rod 11 to rotate, which in turn drives the locking rod 12 to move. The collar 13 on the base 9 guides and limits the locking rod 12, ensuring that the bent rod 15 on the locking rod 12 accurately engages with the insertion hole 7 of the connecting column 5, forming a stable mechanical connection. This locks the first mounting plate 1 and the second mounting plate 2, preventing them from loosening in complex environments such as seawater impact, and ensuring the netting's fixing effect. The arc-shaped spring plate 4 is an open ring, and its opening facilitates the threading of ropes, making it easy to connect the fixed netting device to other aquaculture facilities, thus completing the entire fixing work of the marine aquaculture netting.
