Description

Technical Field

[0001] This utility model relates to the field of aquaculture cage technology, specifically to an anchoring device for aquaculture cages. Background Technology

[0002] With the continuous advancement of marine aquaculture technology, the application of aquaculture cages is becoming increasingly widespread. Among various marine aquaculture facilities, aquaculture cage mooring devices play a crucial role. Their main function is to securely fix the aquaculture cages in the designated sea area, ensuring that the cages maintain a relatively stable position even when facing complex marine environmental factors such as wind, waves, and currents, thus providing a safe and suitable growth space for the cultured organisms. According to announcement number CN206713803U, a single-point mooring circular deep-water cage is disclosed. This technology discloses that it "includes a frame system, a single-point mooring system, and a netting system. The single-point mooring system is composed of rope groups and an anchoring mechanism. The frame system has a circular floating tube frame, and the netting system is hung on the circular floating tube frame. The frame system is characterized by: the frame system also having an A-shaped auxiliary floating tube frame, which is composed of floating tubes. One end of the two inclined sides of the A-shaped auxiliary floating tube frame is connected as the mooring point of the frame system. The other ends of the two inclined sides of the A-shaped auxiliary floating tube frame are connected to the circular floating tube frame by a first connecting rope and a second connecting rope, respectively. The center of the horizontal side of the A-shaped auxiliary floating tube frame is connected to the circular floating tube frame by a third connecting rope, etc. This utility model can make the circular floating tube frame less prone to deformation and breakage, and meets the working characteristics of the single-point mooring method, etc." However, the above technical solution still has some problems in use: First, single-point mooring systems are difficult to cope with complex sea conditions. This solution relies on a single anchor point for fixation and lacks multi-directional restraint. When encountering strong winds, rapid currents, or waves, the aquaculture cages are prone to significant displacement or swaying, resulting in insufficient mooring stability and seriously affecting the mooring device's fixation effect on the cages. Secondly, the anchoring height is not adjustable, resulting in poor adaptability. Since different aquaculture species have different water depth requirements, and the sea level is subject to tidal and seasonal changes, the fixed-height net cages in this scheme cannot be adjusted to the optimal aquaculture water depth according to actual needs. This not only limits the adaptability of aquaculture, but may also increase the stress on the anchoring system due to water level fluctuations, reducing the overall efficiency of the device. Utility Model Content

[0003] To address the problems of insufficient stability and poor adaptability of existing anchoring devices that use single-point anchoring and have no adjustable anchoring height, the purpose of this utility model is to provide an anchoring device for aquaculture cages.

[0004] To solve the above technical problems, the present invention adopts the following technical solution: a cage anchoring device for aquaculture includes anchor rods distributed in a rectangular array, with connecting grooves on the outer surface of the anchor rods, and a support frame fixedly connected to the inner side of the anchor rods. An adjustment mechanism is provided on one side of the support frame, and a frame is provided on one side of the adjustment mechanism. The anchor rods are stainless steel rods, and both the support frame and the frame are stainless steel frames. A cage body is movably installed inside the frame, and a positioning ring is fixedly connected to the upper surface of the cage body. Positioning components are arranged in a circular array on the upper surface of the positioning ring and the frame.

[0005] Preferably, the positioning component includes a ring array of slots on the upper surface of the frame. The inner wall of the slots is movably engaged with a positioning block. The upper surface of the positioning ring is provided with a ring array of positioning grooves. The positioning block is movably engaged inside the positioning groove. The outer surface shape of the positioning block matches the inner wall shape of the slot and the positioning groove. The corresponding positioning block and the slot are threaded together with positioning bolts.

[0006] Preferably, the adjustment mechanism includes a connecting shell, which is fixedly installed on one side of the support frame. A servo motor is fixedly installed on the upper surface of the connecting shell, and a protective shell for use with the servo motor is fixedly installed on the upper surface of the connecting shell. The servo motor is fixedly installed inside the protective shell. The output end of the servo motor passes through the upper surface of the connecting shell and is fixedly connected to a lead screw. The bottom end of the lead screw is damped and rotatably connected to the inner wall of the connecting shell. A slider is threaded on the outer surface of the lead screw, and connecting rods are symmetrically fixedly connected to both sides of the slider. Guide grooves for use with the connecting rods are symmetrically opened on both sides of the connecting shell. The connecting rods are slidably connected to the inner walls of the guide grooves. A connecting block is fixedly connected to one side of the connecting rod, and one side of the connecting block is fixedly connected to one side of the frame. Guide sleeves are fixedly connected in a ring array on the outer surface of the frame, and the corresponding guide sleeves are slidably connected to the outer surface of the corresponding anchor rods.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This application constructs a multi-point positioning and mooring system through positioning components. Compared with the traditional single-point mooring method, it can apply restraint forces to the cage from multiple directions. Under complex sea conditions such as strong winds and rapid currents, multi-point positioning can effectively disperse external forces, significantly reduce the displacement and swaying of the cage, and greatly improve mooring stability, thereby achieving a more stable and reliable fixing effect for the cage. 2. This application, through its adjustment mechanism, allows for flexible adjustment of the anchoring height according to actual aquaculture conditions, ensuring that the net cages are always at the optimal aquaculture water depth. This not only improves the adaptability of aquaculture but also enhances the overall efficiency of the device. Attached Figure Description

Detailed Implementation

[0014] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example: like Figures 1 to 4 As shown, this utility model provides a cage anchoring device for aquaculture, including anchor rods 1 arranged in a rectangular array. The anchor rods 1 arranged in a rectangular array achieve multi-point positioning. Compared with single-point anchoring, the cage can be constrained from multiple directions, external forces can be dispersed, and anchoring stability can be improved. The outer surface of the anchor rods 1 is provided with a connecting groove 6. The connecting groove 6 on the outer surface of the anchor rods 1 facilitates connection and fixation with other components, enhancing the assembly flexibility of the overall structure.

[0016] See Figure 1The anchor rod 1 is fixedly connected to the support frame 5 on its inner side. The support frame 5 has an adjustment mechanism 3 on one side and a frame 7 on the other side. The connecting groove 6 on the outer surface of the anchor rod 1 facilitates connection and fixation with other components, enhancing the assembly flexibility of the overall structure. The anchor rod 1 is made of stainless steel, and the support frame 5 and frame 7 are also made of stainless steel. The use of stainless steel in the anchor rod 1, support frame 5, and frame 7 provides excellent corrosion resistance, allowing for long-term use in seawater environments without rusting or damage, extending the service life of the mooring device and reducing maintenance costs. The frame 7 has a movable gabion body 8 inside, providing installation space for the gabion body 8 and ensuring the stability of the gabion during mooring. The upper surface of the gabion body 8 is fixedly connected to a positioning ring 4. The positioning ring 4 and the positioning component 2 are arranged in a ring array on the upper surface of the frame 7. The positioning ring 4 and the positioning component 2 work together to firmly fix the gabion body 8 to the frame 7, preventing the gabion from shaking or shifting under the impact of water flow, further improving the mooring device's fixation effect on the gabion.

[0017] See Figure 2 The positioning component 2 includes a ring array of slots 22, which are arranged in a ring array on the upper surface of the frame 7. A positioning block 23 is movably engaged with the inner wall of the slot 22. A positioning groove 24 is arranged in a ring array on the upper surface of the positioning ring 4. The positioning block 23 is movably engaged with the inside of the positioning groove 24. The design of the ring array of slots 22, positioning blocks 23 and positioning groove 24 makes the positioning ring 4 and the frame 7 fixed at multiple points, further enhancing the fixing strength of the cage body 8 and forming a multi-point positioning effect.

[0018] See Figure 2 The outer surface shape of the positioning block 23 matches the inner wall shape of the slot 22 and the positioning groove 24. The positioning block 23 matches the shape of the slot 22 and the positioning groove 24 to ensure accurate positioning. The corresponding positioning block 23 and the slot 22 are threadedly connected with positioning bolts 21. The positioning bolts 21 are easy to install and remove, making it convenient to install, disassemble and maintain the cage body 8.

[0019] See Figure 3 and Figure 4The adjustment mechanism 3 includes a connecting shell 33, which is fixedly installed on one side of the support frame 5. A servo motor 35 is fixedly installed on the upper surface of the connecting shell 33, and a protective shell 34 for use with the servo motor 35 is fixedly installed on the upper surface of the connecting shell 33. The servo motor 35 is fixedly installed inside the protective shell 34, which protects the servo motor 35 from damage caused by seawater, debris, etc. The output end of the servo motor 35 passes through the upper surface of the connecting shell 33 and is fixedly connected to a lead screw 36. The servo motor 35 drives the lead screw 36 to rotate, and the bottom end of the lead screw 36 is damped and rotated in a rotatable connection with the inner wall of the connecting shell 33. This damped rotational connection prevents the lead screw 36 from rotating accidentally. Furthermore, the lead screw 36 is treated with anti-corrosion and anti-rust measures.

[0020] See Figure 4 A slider 37 is threaded onto the outer surface of the lead screw 36, driving the slider 37 to move up and down along the lead screw 36 to achieve precise adjustment of the height of the frame 7. Connecting rods 38 are symmetrically fixedly connected to both sides of the slider 37. Guide grooves 32 that cooperate with the connecting rods 38 are symmetrically opened on both sides of the connecting shell 33. The connecting rods 38 are slidably connected to the inner wall of the guide grooves 32. The guide grooves 32 cooperate with the connecting rods 38 to guide the movement of the slider 37, preventing the slider 37 from deviating or shaking during the movement, and ensuring that the adjustment process is smooth and reliable. A connecting block 39 is fixedly connected to one side of the connecting rod 38, and one side of the connecting block 39 is fixedly connected to one side of the frame 7. The connecting rods 38 and the connecting block 39 connect the slider 37 to the frame 7, so that the movement of the slider 37 can drive the frame 7 to rise and fall synchronously.

[0021] See Figure 3 The outer surface of the frame 7 is fixedly connected with a ring array of guide sleeves 31. The corresponding guide sleeves 31 are slidably connected to the outer surface of the corresponding anchor rods 1. The guide sleeves 31 and the anchor rods 1 are slidably engaged, which further enhances the stability of the frame 7 during the lifting process, prevents the frame 7 from tilting or shaking, and ensures that the cage body 8 is always at the ideal aquaculture water depth.

[0022] Working principle: First, the rectangular array of anchor bolts 1 is inserted into the seabed. It can be further connected to other auxiliary fixing structures through the connecting groove 6 on the outer surface to enhance the anchoring stability.

[0023] The support frame 5 on the inner side of the anchor rod 1 connects each anchor rod 1, providing support for the subsequent structure.

[0024] The cage body 8 is placed inside the frame 7 and fixed by the positioning component 2. The slots 22 of the ring array on the upper surface of the frame 7 are aligned with the positioning grooves 24 on the positioning ring 4. The positioning block 23 is inserted into the slots 22 and the positioning grooves 24. The positioning block 23 is threadedly connected to the slots 22 by the positioning bolt 21, so that the positioning ring 4 is firmly connected to the frame 7, thereby fixing the cage body 8.

[0025] The positioning block 23 matches the shape of the card slot 22 and the positioning groove 24 to ensure accurate positioning and tight connection.

[0026] When it is necessary to adjust the aquaculture water depth of the cage body 8, the servo motor 35 in the adjustment mechanism 3 is started. The output end of the servo motor 35 drives the lead screw 36 to rotate. When the lead screw 36 rotates, the threaded slider 37 moves up and down along the lead screw 36.

[0027] The connecting rods 38 on both sides of the slider 37 slide in the guide grooves 32 of the connecting shell 33, which serves as a guide to prevent the slider 37 from deviating. The connecting rods 38 are connected to the frame 7 through the connecting block 39, which drives the frame 7 to rise and fall synchronously.

[0028] The guide sleeve 31 on the outer surface of the frame 7 slides with the anchor rod 1, further enhancing the stability of the frame 7 during the lifting process, so that the cage body 8 can be smoothly adjusted to the appropriate aquaculture water depth.

[0029] The anchoring effect of the anchoring device is improved by using the positioning component 2 and the adjustment mechanism 3 together.

[0030] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
