Description

Technical Field

[0001] This utility model relates to the field of aquaculture cage technology, and in particular to a floating tube limiting device for aquaculture cages. Background Technology

[0002] Aquaculture cages are an important type of aquaculture equipment in the aquaculture industry. Existing aquaculture cages typically consist of components such as a frame, floats, netting, sinkers, and cables. The frame has perforations through which the floats pass, providing buoyancy to the entire cage and allowing it to float on the water. The netting is housed within the frame, and a walking platform is provided at the top of the frame for personnel to access.

[0003] However, during the use of aquaculture cages, the diameter of the holes in the frame is slightly larger than the outer diameter of the floating pipes, creating a gap between the holes and the floating pipes. Furthermore, existing aquaculture cages lack effective limiting mechanisms between the floating pipes and the frame. This causes the floating pipes to easily move axially relative to the frame under the influence of wind and waves, and there is also relative rotation between the floating pipes and the frame. This affects the stability of the entire aquaculture cage frame. Moreover, the continuous friction and collision between the floating pipes and the frame holes will cause the holes in the frame to gradually enlarge and deform, affecting the strength and stability of the frame, and thus shortening the service life of the entire aquaculture cage. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies and provide a limiting device for the floating tubes of aquaculture cages.

[0005] The purpose of this utility model is achieved through the following technical solution: a floating tube limiting device for aquaculture net cages, comprising a frame unit, a floating tube, and a stop block. The frame unit is provided with a tube hole for the floating tube to pass through. The stop block is fixed on the outer wall of the floating tube and is located on both sides of the frame unit and abuts against the frame unit. A rotation limiting mechanism is provided between the stop block and the frame unit to limit the rotation of the floating tube in the tube hole.

[0006] Preferably, the block is provided with a plurality of weight-reducing grooves, and the weight-reducing grooves form a reinforcing rib structure.

[0007] Preferably, the end of the stop block near the float tube is provided with an arc surface that matches the outer wall of the float tube.

[0008] Preferably, the rotation limiting mechanism includes a limiting groove disposed on the frame unit and an extension disposed on the stop block, the width of the extension being the same as the width of the limiting groove, and the extension extending into the limiting groove.

[0009] Preferably, the rotation limiting mechanism includes a fixing rib on the support unit and a slot at one end of the stop block, with the fixing rib inserted into the slot; the fixing rib is integrally formed with the frame unit.

[0010] Preferably, the rotation limiting mechanism includes a limiting protrusion group disposed on both sides of the frame unit, the limiting protrusion group including two limiting protrusions, and a stop block disposed between the limiting protrusion group.

[0011] Preferably, the rotation limiting mechanism includes a limiting body fixedly mounted on the frame unit and a groove mounted on the stop block, with both ends of the limiting body extending out from both sides of the frame unit; the end of the limiting body extends into the groove on the stop block.

[0012] The beneficial effects of this utility model are: this utility model can effectively limit the floating tube, effectively avoid the relative movement or rotation between the floating tube and the frame unit, improve the stability of the entire aquaculture cage frame, reduce the friction and collision between the floating tube and the frame tube hole, thereby reducing the material wear of the frame unit and the floating tube, and improving the service life of the entire aquaculture cage.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art are within the protection scope of the present utility model.

[0023] Example 1:

[0024] like Figures 1 to 3 As shown, a limiting device for a floating tube 2 of an aquaculture net cage includes a frame unit 1, a floating tube 2, and a stop block 3. The frame unit 1 is provided with a tube hole for the floating tube 2 to pass through. The stop block 3 is fixed to the outer wall of the floating tube 2 and is located on both sides of the frame unit 1 and abuts against the frame unit 1. A rotation limiting mechanism is provided between the stop block 3 and the frame unit 1 to limit the rotation of the floating tube 2 in the tube hole.

[0025] Among them, the block 3 is provided with several weight-reducing grooves 3-1, and the weight-reducing grooves 3-1 form a reinforcing rib structure 3-2.

[0026] One end of the stop block 3 near the float tube 2 is provided with an arc-shaped surface 3-3 that fits the outer wall of the float tube 2. The arc-shaped surface 3-3 on the stop block 3 fits against the outer wall of the float tube 2. The arc-shaped surface 3-3 can form a large contact area with the outer wall of the float tube 2. The arc-shaped surface 3-3 on the stop block 3 is fixedly bonded to the outer wall of the float tube 2 with hot melt adhesive.

[0027] In this embodiment, the rotation limiting mechanism includes a limiting groove 1-1 disposed on the frame unit 1 and an extension 3-4 disposed on the stop block 3. The width of the extension 3-4 is the same as the width of the limiting groove 1-1, and the extension 3-4 extends into the limiting groove 1-1.

[0028] The stop block 3 is set on both sides of the frame unit 1 and abuts against the frame unit 1. The stop block 3 achieves axial limit of the float tube 2, which can effectively prevent the float tube 2 from moving axially in the tube hole. At the same time, the extension part 3-4 on the stop block 3 extends into the limiting groove 1-1. The cooperation between the extension part 3-4 and the limiting groove 1-1 can effectively prevent the float tube 2 from rotating relative to the frame unit 1.

[0029] This invention can effectively limit the floating tube 2, effectively preventing relative movement or rotation between the floating tube 2 and the frame unit 1, improving the stability of the entire aquaculture cage frame, reducing friction and collision between the floating tube 2 and the frame tube holes, thereby reducing material wear of the frame unit 1 and the floating tube 2, and improving the service life of the entire aquaculture cage.

[0030] Example 2:

[0031] like Figures 4 to 5 As shown, the difference between Embodiment 2 and Embodiment 1 is that in Embodiment 2, the rotation limiting mechanism includes a fixing rib 1-2 disposed on the support unit and a slot 3-5 disposed at one end of the stop block 3, with the fixing rib 1-2 inserted into the slot 3-5; the fixing rib 1-2 is integrally formed with the frame unit 1. When installing the stop block 3, the fixing rib 1-2 on the frame support is inserted into the slot 3-5 on the stop block 3, and then the stop block 3 is fixed to the outer wall of the float tube 2 with hot melt adhesive. Through the cooperation between the slot 3-5 and the fixing rib 1-2, the rotation of the float tube 2 relative to the frame unit 1 can be effectively prevented.

[0032] The remaining structures of Example 2 are the same as those in Example 1.

[0033] Example 3:

[0034] like Figure 6 As shown, the rotation limiting mechanism includes a set of limiting protrusions 1-3 disposed on both sides of the frame unit 1. Each set of limiting protrusions 1-3 includes two limiting protrusions 1-3, and a stop block 3 is disposed between the sets of limiting protrusions 1-3. The limiting protrusions 1-3 are integrally formed with the frame unit 1. Through the limiting action of the limiting protrusions 1-3, the rotation of the float tube 2 relative to the frame unit 1 can be effectively prevented.

[0035] The remaining structures of Example 3 are the same as those of Example 1.

[0036] Example 4:

[0037] like Figures 7 to 8 As shown, the rotation limiting mechanism includes a limiting body 4 fixedly mounted on the frame unit 1 and a groove 3-6 provided on the stop block 3. Both ends of the limiting body 4 extend out from both sides of the frame unit 1; the end of the limiting body 4 extends into the groove 3-6 on the stop block 3. The limiting body 4 is fixed to the frame unit 1 by hot melt adhesive. The cooperation between the limiting body 4 and the groove 3-6 on the stop block 3 effectively prevents the float tube 2 from rotating relative to the frame unit 1.

[0038] The remaining structures of Example 4 are the same as those in Example 1.

[0039] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
