Abstract
Description
Technical Field
[0001] The invention relates to the technical field of marine aquaculture equipment, in particular to a marine air bag arranged at the bottom of a net cage. Background Art
[0002] In the field of marine fisheries and aquaculture, cage aquaculture is a widely used aquaculture method. In order to maintain the stability and buoyancy of the cage in the water, it is often necessary to install an air bag at the bottom of the cage. However, the traditional air bag installation method has many inconveniences and limitations.
[0003] Traditional airbags usually have fixed specifications and sizes. Once installed, it is difficult to adjust or replace them according to actual needs. In the actual breeding process, due to changes in breeding scale, breeding species or breeding environment, airbags of different specifications may need to be used to provide appropriate buoyancy. However, the fixed specifications of traditional airbags make such adjustments very difficult, and it is often necessary to dismantle and reinstall new airbags, which is not only time-consuming and labor-intensive, but may also damage the structure and stability of the cage.
[0004] In addition, the traditional installation method of airbags also lacks flexibility and adaptability. Usually, the airbags are directly fixed to the bottom of the cage by fixings or lashings. This fixing method is not only troublesome to install, but also difficult to ensure the stability of the airbags in the complex and changeable marine environment. When the wind and waves are strong or the floating of the cage changes, the airbags may shift or fall off due to loose fixation, thus affecting the stability and buoyancy support of the cage.
[0005] In order to solve the above problems, people are in urgent need of a marine airbag device that can quickly adapt to airbag bodies of different specifications. Summary of the invention
[0006] The present invention proposes a marine airbag, which, through a unique structural design, can achieve rapid adjustment of airbag specifications and stable installation to adapt to different breeding needs and environmental conditions.
[0007] The above technical objectives of the present invention are achieved through the following technical solutions: A marine airbag, arranged at the bottom of a net cage, comprising: Two symmetrically arranged airbag bodies, the two airbag bodies are respectively placed on two movable rails, and the movable rails are hollow long strip structures; A fixed rail, wherein the fixed rail is in a cross structure, the four ends of the cross structure are fixed on the bottom surface of the net box, and each end of the cross structure is provided with a mutually independent and unconnected slide groove to the cross intersection of the cross structure, and the movable rail is slidably mounted on two adjacent slide grooves; A positioning seat is provided at both ends of each movable rail, the ends of the airbag body are detachably connected to the positioning seat, a bottom column is provided at the bottom of the positioning seat, the positioning seat is placed on the movable rail and cannot pass through the hollow of the movable rail, and the bottom column passes through the hollow of the movable rail and extends into the slide groove and can slide along the slide groove.
[0008] In some embodiments, both ends of the airbag body are provided with connecting heads, and the positioning seat is provided with connecting holes adapted to the connecting heads. The connecting heads and the connecting holes are detachably combined together, and the detachable combination adopts a locking mechanism that is easy to quickly install and disassemble.
[0009] In some embodiments, the locking mechanism is a threaded tightening, the connector is provided with an external thread, the connecting hole is provided with an internal thread that matches the external thread, and the external thread and the internal thread are matched with each other by rotating the connector.
[0010] In some embodiments, a toothed ring is provided on the upper hoop of the airbag body, and a toothed plate is provided at the bottom of the mesh box. The toothed plate is meshed with the toothed ring, and the length direction of the toothed plate is consistent with the moving direction of the movable rail.
[0011] In some embodiments, a handle is provided on the movable rail.
[0012] In some embodiments, each of the movable rails is provided with two symmetrical handles, both of which are in an inverted U-shape and protrude upward and are respectively provided on both sides of the airbag body.
[0013] Compared with the prior art, the present invention has the following beneficial effects: The present invention realizes the rapid adaptation of the airbag body through the mutual cooperation of the movable rail and the fixed rail, as well as the limiting and guiding functions of the positioning seat and the bottom column. The airbag bodies of different specifications can be easily switched and installed only by sliding and adjusting the movable rail. When the specifications of the airbag need to be adjusted, the operator only needs to push or pull the movable rail to translate along the slide groove of the fixed rail to quickly adjust the distance between the two positioning seats to adapt to larger or smaller specifications of the airbag body. This adjustment method is not only simple and easy, but also greatly improves the flexibility and adaptability of the airbag installation. Different breeding needs and environmental changes can be quickly met without disassembling or reinstalling the airbag. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] See also Figure 1-7 This embodiment provides a marine airbag, which is arranged at the bottom of the cage 100, including: Two airbag bodies 1 are symmetrically arranged, and the two airbag bodies 1 are placed on two movable rails 2 respectively. The movable rails 2 are hollow strip-shaped structures. The hollow structure can reduce weight on the one hand, and can clamp the cylindrical airbag body 1 on the other hand, so that the airbag body 1 is difficult to roll off the movable rails 2; The fixed rail 4 is a cross structure, and the four ends of the cross structure are fixed on the bottom surface of the net box 100, providing a stable support foundation. Each end of the cross structure is provided with a mutually independent and unconnected slide groove 401 from the cross intersection of the cross structure, and the movable rail 2 is slidably mounted on two adjacent slide grooves 401; A positioning seat 3 is provided at both ends of each movable rail 2, and the end of the airbag body 1 is detachably connected to the positioning seat 3. A bottom column 302 is provided at the bottom of the positioning seat 3. The positioning seat 3 is placed on the movable rail 2 and cannot pass through the hollow of the movable rail 2. The bottom column 302 penetrates the hollow of the movable rail 2 and extends into the slide groove 401 and can slide along the slide groove 401. In other words, the positioning seat 3 and the bottom column 302 are both arranged at the overlapping and intersecting part of the hollow of the movable rail 2 and the slide groove 401.
[0021] The positioning seat 3 and the bottom column 302 are used to prevent the movable rail 2 from separating from or deviating from the fixed rail 4, and the two also limit the moving direction of the movable rail 2, so that the movable rail 2 can only be translated in the direction away from or close to the cross intersection of the cross structure. During this period, the positioning seat 3 and the bottom column 302 both move along the slide groove 401. When the movable rail 2 moves in the direction away from the cross intersection of the cross structure, the two positioning seats 3 on the movable rail 2 will move away from each other. At this time, the distance between the two positioning seats 3 increases to adapt to a larger specification of the airbag body 1. When the movable rail 2 moves in the direction close to the cross intersection of the cross structure, the two positioning seats 3 on the movable rail 2 will gather together. At this time, the distance between the two positioning seats 3 is reduced to adapt to a smaller specification of the airbag body 1. Therefore, the present invention can easily switch to install airbag bodies 1 of different specifications only by sliding the movable rail 2.
[0022] The working principle of the present invention is based on the mutual cooperation between the movable rail 2 and the fixed rail 4, as well as the limiting and guiding functions of the positioning seat 3 and the bottom column 302. Specifically, when the airbag specifications need to be adjusted, the operator pushes or pulls the movable rail 2 to make it translate along the slide groove 401 of the fixed rail 4. The movement of the movable rail 2 drives the positioning seat 3 and the bottom column 302 to slide in the slide groove 401. Since the positioning seat 3 cannot pass through the hollow of the movable rail 2, and the bottom column 302 penetrates the hollow and extends into the slide groove 401, the moving direction of the movable rail 2 is limited to the direction along the slide groove 401. When the movable rail 2 moves in the direction away from the cross intersection, the two positioning seats 3 move away from each other, and the distance between them increases, so as to adapt to the larger specifications of the airbag body 1; otherwise, it adapts to the smaller specifications of the airbag body 1.
[0023] When installing the airbag, first fix the four ends of the fixed rail 4 to the bottom surface of the cage 100 to ensure the stability of the fixed rail 4. Then slide the movable rail 2 on the two adjacent slide grooves 401, and prevent the movable rail 2 from separating from the fixed rail 4 or running off through the limiting effect of the positioning seat 3 and the bottom column 302. Finally, the end of the airbag body 1 is detachably connected to the positioning seat 3 to complete the installation and positioning of the airbag.
[0024] During use, the cross structure of the fixed rail 4 and the independent and non-interconnected design of the slide 401, as well as the limiting and guiding functions of the positioning seat 3 and the bottom column 302, ensure the stable operation and precise positioning of the airbag at the bottom of the cage 100. Even in the face of the complex and changeable marine environment and the floating changes of the cage 100, the airbag can maintain a stable operating state and provide continuous buoyancy support and stability for the cage 100.
[0025] In some embodiments, Figure 2 and 4 As shown, both ends of the airbag body 1 are provided with connectors 101, and the positioning seat 3 is provided with a connecting hole 301 adapted to the connector 101. The connector 101 and the connecting hole 301 are detachably combined together, and the detachable combination adopts a locking mechanism that is easy to quickly install and disassemble.
[0026] Preferably, Figure 7As shown, the locking mechanism is a thread tightening, the connector 101 is provided with an external thread, and the connecting hole 301 is provided with an internal thread adapted to the external thread. By rotating the connector 101, the external thread and the internal thread cooperate with each other to achieve a tight connection between the airbag body 1 and the positioning seat 3. The thread tightening can provide a large clamping force to ensure that the connection between the airbag body 1 and the positioning seat 3 is very stable. Even if it is subjected to a large external force in the marine environment, such as wave impact, water surge, etc., the connection will not easily loosen or fall off, ensuring the continuous and stable operation of the airbag. Moreover, the operation method of thread tightening is very simple, and tightening or loosening can be achieved by rotating the connector 101. This operation method does not require special tools or complicated steps, which greatly improves the efficiency of installation and disassembly.
[0027] Preferably, Figure 6 As shown, a toothed ring 102 is provided on the upper hoop of the airbag body 1, and a toothed plate 5 is provided at the bottom of the net box 100, the toothed plate 5 is meshed with the toothed ring 102, and the length direction of the toothed plate 5 is consistent with the moving direction of the movable rail 2; when the movable rail 2 moves along the slide groove 401 of the fixed rail 4, due to the meshing action of the toothed ring 102 and the toothed plate 5, the airbag body 1 will rotate due to the force of the toothed plate 5 while moving linearly with the movable rail 2, and this rotational motion is performed around the axis of the airbag body 1, which is perpendicular to the moving direction of the movable rail 2, and because the connectors 101 at both ends of the airbag body 1 are designed with external threads, The connecting hole 301 of the positioning seat 3 is provided with a corresponding internal thread. Therefore, when the airbag body 1 rotates, the external thread on the connecting head 101 will automatically screw into the internal thread in the connecting hole 301, thereby realizing the fastening connection between the airbag body 1 and the positioning seat 3. This synchronous assembly method does not require the operator to manually rotate the connecting head 101, which greatly simplifies the installation process. During the entire process, the operator only needs to place the airbag body 1 on the movable rail 2, and ensure that the gear ring 102 is correctly engaged with the gear plate 5, and then push or pull the movable rail 2. No additional rotation operation or special tools are required, making the installation process simpler and more convenient.
[0028] In some embodiments, Figure 1 or Figure 3 As shown, the movable rail 2 is provided with a handle 201, which is designed in an ergonomic shape, so that the operator can grasp and apply force, making it easier and more labor-saving to push or pull the movable rail 2 along the slide groove 401 of the fixed rail 4. The design of the handle 201 allows the operator to move the movable rail 2 more easily without spending too much effort or time. This greatly improves the installation, adjustment and maintenance efficiency of the marine airbag system.
[0029] Preferably, Figure 1 or Figure 3As shown, each movable rail 2 is provided with two symmetrical handles 201, both handles 201 are inverted U-shaped and protrude upward and are respectively arranged on both sides of the airbag body 1. On the one hand, the two symmetrically arranged handles 201 provide the operator with more gripping options. No matter which side of the movable rail 2 the operator stands on, he can easily find a suitable handle 201 for gripping. On the other hand, the inverted U-shaped handle 201 design conforms to the ergonomic principle, and the protruding part can provide a better grip and support force, making the operator more stable and labor-saving when pushing or pulling the movable rail 2. In addition, the two symmetrically arranged handles 201 form an effective barrier on both sides of the airbag body 1 to prevent the airbag body 1 from rolling down on the movable rail 2. The presence of the handle 201 can effectively limit the moving range of the airbag body 1, ensuring that it is always stably placed on the movable rail 2, and the inverted U-shaped design of the handle 201 enables its protruding part to fit tightly on the side of the airbag body 1, further enhancing the blocking effect. Even if the airbag body 1 is subjected to a large external force, it is difficult for it to escape from the obstruction of the handle 201 , thereby ensuring the safety and stability of the airbag body 1 .
[0030] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
