Description

Technical Field

[0001] This invention relates to the field of aquaculture equipment technology, and in particular to a typhoon-resistant net cage. Background Technology

[0002] With the rapid development of aquaculture, typhoon-resistant cages have become an important facility for ensuring the safety of marine fisheries. Typhoon-resistant cages are mainly divided into two types: floating and stationary. Floating cages generally use mooring systems for positioning, and steel cables or chains restrain the drift of the cages. Due to the addition of mooring systems, the sea area of ​​a single cage increases, resulting in low utilization of the ocean area and low economic returns. Therefore, stationary cages are more commonly used. However, to achieve better typhoon resistance, stationary cages need to stack more reinforcing steel horizontal or diagonal braces, which increases the cost of the cages.

[0003] Therefore, it is necessary to develop a new type of typhoon-resistant cage that has good typhoon resistance performance, low cost, and high sea-drop density. Summary of the Invention

[0004] To address the aforementioned shortcomings, the present invention aims to propose a typhoon-resistant gabion, which replaces purely rigid resistance with flexible resistance to reduce structural costs and enhance adaptive typhoon resistance. By coupling the anti-tensioner with the folding cross brace structure, the deformation of the folding cross brace under typhoon load pulls the anti-tensioner to generate an adjustable restoring force, thereby improving the gabion's typhoon resistance.

[0005] To achieve this objective, the present invention adopts the following technical solution: A typhoon-resistant gabion includes several support columns and a two-layer mesh structure. Each layer of the mesh structure includes several folding cross braces, several tension ropes, several first connecting rods, and a central connecting plate. The first connecting rods are equipped with anti-tensioners. Several of the support columns are arranged vertically and circumferentially, and several of the folding cross braces are provided between two adjacent support columns. The two ends of the folding cross braces are respectively hinged to the two adjacent support columns. The several support columns and several of the folding cross braces enclose an internal space. The two central connecting plates are respectively set at the top and bottom of the cage, and a number of first connecting rods are radiating along the central connecting plates. One end of the first connecting rod is connected to the central connecting plate, and the other end is perpendicularly connected to the support column. The folding point of the folding cross brace is the connection point. One end of the traction rope is connected to the connection point on the folding cross brace, and the other end is connected to the corresponding anti-tensioner. When the cage is subjected to a force, the folding cross brace undergoes expansion or contraction deformation. The connection point is displaced with the deformation and simultaneously pulls the corresponding tension rope to generate tension against the tensioner. This drives the corresponding anti-tensioner to generate a restoring force that resists the tension. The restoring force acts in the opposite direction on the connection point through the tension rope to resist the deformation of the folding cross brace.

[0006] Preferably, the folding cross brace includes several crossbars and several first connecting plates. The several crossbars are divided into left and right groups along the length of the folding cross brace, and each group includes 4 crossbars. The left and right ends of the crossbars are respectively provided with two second connecting plates that are spaced apart in the vertical direction. The support column is provided with a connecting base, and the connecting base is hinged with two third connecting plates in the vertical direction. Each third connecting plate has two strip holes on the left and right sides. The strip holes on the same third connecting plate are movably connected to one end of different crossbars respectively. A plurality of first connecting plates are arranged at intervals along the vertical direction, and each of the four corners of the first connecting plate has a strip hole. The strip hole of the same first connecting plate is movably connected to the other end of different crossbars. The upper and lower adjacent crossbars are fixedly connected by a third connecting rod. For any set of crossbars, the third connecting rod passes through a second connecting plate, the strip hole and another second connecting plate from top to bottom in sequence. The third connecting plate and the first connecting plate are partially embedded in the gap between the second connecting plates. Through the connection of the third connecting rod, the upper and lower adjacent crossbars can slide synchronously relative to the first connecting plate and the third connecting plate along the length direction of the strip hole, and / or rotate around the axis of the third connecting rod.

[0007] Preferably, the tensioner has a telescopic tube with a sealed cavity inside, the cavity is filled with gas at a preset pressure, and the outer end of the telescopic tube is connected to the tension rope.

[0008] Preferably, each of the folding cross braces is provided with two connection points, and the two connection points are respectively connected to the tensioners on the first connecting rods adjacent to each other on both sides of the folding cross brace through two tension ropes.

[0009] Preferably, the two connection points are located in the middle of the folding cross brace and are symmetrically distributed on the left and right.

[0010] Preferably, the number of folding cross braces between two adjacent support columns is two, and the two folding cross braces are symmetrically and parallelly distributed vertically.

[0011] Preferably, a second connecting rod is vertically connected between the two symmetrically parallel folding cross braces, and the two ends of the second connecting rod are respectively fixedly connected to the folding points of the two folding cross braces.

[0012] Preferably, the third connecting plates include a fourth connecting plate arranged in a vertical direction, a guide wheel is provided between the fourth connecting plates, and two strip holes are opened on the fourth connecting plates, corresponding to the third connecting rod passing through the strip holes on the fourth connecting plates; Each of the first connecting rods has a guide wheel at one end near the support column, and the pull rope passes over the guide wheel between the fourth connecting plates and the guide wheel on the first connecting rod.

[0013] Preferably, the support column is provided with a lifting rack, and the support column includes a lifting component that can move up and down along the lifting rack. The connecting base is provided on the lifting component, and the first connecting rod is hinged to the lifting component.

[0014] Preferably, a fourth connecting rod is fixedly connected between the two first connecting plates of the same folding cross brace; The two connection points are located on the fourth connecting rod and are symmetrically distributed on the left and right.

[0015] One of the above technical solutions has the following advantages or beneficial effects: This invention uses support columns to enclose the internal aquaculture space. The first connecting rods radially connect to the central connecting plate to form an overall support frame. When a typhoon load acts on the cage, the folding cross brace deforms and drives the anti-tensioner on the first connecting rod through the synchronous traction rope at the connection point. This causes the telescopic tube in the internal sealed cavity to generate a restoring force positively correlated with the deformation under gas pressure. This restoring force acts in the opposite direction at the connection point of the folding cross brace via the traction rope to resist the development of deformation. As a result, the cage does not need to stack steel cross braces or diagonal braces to enhance its typhoon resistance, successfully reducing the cost of the cage. At the same time, the pile-type design of this invention avoids dependence on the mooring system, which can significantly reduce the sea area occupied by a single cage. Attached Figure Description

Detailed Implementation

[0018] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0019] In this invention, the terms "comprising," "including," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0020] A type of typhoon-resistant cage, such as Figure 1 , 3 As shown in Figure 4, it includes several support columns 1 and a two-layer mesh structure. Each layer of the mesh structure includes several folded cross braces 2, several tension ropes, several first connecting rods 4 and a central connecting plate 5. The first connecting rods 4 are provided with anti-tensioners 41. Several support columns 1 are arranged vertically and circumferentially, and several folding cross braces 2 are provided between two adjacent support columns 1. The two ends of the folding cross braces 2 are respectively hinged to the two adjacent support columns 1. Several support columns 1 and several folding cross braces 2 enclose an internal space. The two central connecting plates 5 are respectively disposed at the top and bottom of the cage, and a plurality of first connecting rods 4 are distributed radiatingly along the central connecting plates 5. One end of the first connecting rod 4 is connected to the central connecting plate 5, and the other end is perpendicularly connected to the support column 1. The folding point of the folding cross brace 2 is the connection point 21. One end of the traction rope is connected to the connection point 21 on the folding cross brace 2, and the other end is connected to the corresponding anti-tensioner 41. When the cage is subjected to a force, the folding cross brace 2 undergoes expansion or contraction deformation. The connection point 21 is displaced with the deformation and simultaneously pulls the corresponding tension rope to generate tension against the tensioner 41. This drives the corresponding anti-tensioner 41 to generate a restoring force that resists the tension. The restoring force acts in the opposite direction on the connection point 21 through the tension rope to resist the deformation of the folding cross brace 2.

[0021] It should be noted that the support columns 1 are arranged vertically and circumferentially, forming an internal space for the aquaculture area with the folding cross brace 2; the two-layer net structure refers to the net cage being divided into two independent functional layers in the vertical direction, an upper layer and a lower layer, each layer being equipped with a folding cross brace 2, a pull rope, a first connecting rod 4, a central connecting plate 5, and a tensioner 41; the two ends of the folding cross brace 2 are respectively hinged to two adjacent support columns 1, and the folding cross brace 2 is used to bear and transmit external loads in the horizontal direction. In one embodiment, each layer of net structure is a regular hexagonal structure in the horizontal direction; the pull rope, as a force transmission component, is connected at one end to the connection point 21 on the folding cross brace 2, and at the other end to the corresponding tensioner 41; the first connecting rod One end of the first connecting rod 4 is connected to the central connecting plate 5, and the other end is vertically connected to the support column 1, forming a radial overall support frame for the net cage. The vertical connection is beneficial to the transmission of force between the support column 1 and the first connecting rod 4, making the overall structure of the net cage more stable. The two central connecting plates 5 are respectively set at the top and bottom of the net cage to converge and fix each first connecting rod 4 to enhance the overall structure. The tensioner 41 is set on the first connecting rod 4. In the embodiment, a telescopic tube with a sealed cavity can be provided inside the tensioner 41 and the cavity is filled with gas at a preset pressure to generate elastic restoring force when subjected to force. The connection point 21 is set on the folding cross brace 2 as a fixed node of the traction rope, which moves with deformation and drives the traction rope to move.

[0022] Understandably, a rigid frame foundation is constructed through support columns 1, the first connecting rod 4, and the central connecting plate 5. The folding cross brace 2 connects adjacent support columns 1 to form a regular hexagonal horizontal support system. When external forces such as typhoons are applied to the cage, the folding cross brace 2 undergoes elastic deformation. The connection point 21, as the pivot center of the folding action and the fixed node of the tension rope, shifts with the deformation. The tension rope synchronously pulls the telescopic tube inside the tensioner 41, causing it to change from a compressed state to an extended state. Due to the gas pressure inside the telescopic tube, resistance is generated. The anti-stretch restoring force is transmitted in the opposite direction to the connection point 21 through the traction rope, forming a resistance force opposite to the external force, thereby offsetting or weakening the deformation of the folded cross brace 2 and realizing the typhoon resistance function of the cage. By converting the limited deformation of the rigid structure into the storage and release of gas compression energy, the technical effect of dynamic buffering and self-stabilization is achieved. The typhoon resistance can be enhanced without stacking steel cross braces or diagonal braces, successfully reducing the cost. At the same time, the pile-type design avoids dependence on the mooring system and significantly reduces the sea area occupied by a single cage.

[0023] Preferably, such as Figure 2 and Figure 6 As shown, the folding cross brace 2 includes several crossbars 22 and several first connecting plates 23. The several crossbars 22 are divided into left and right groups along the length direction of the folding cross brace 2. Each group includes 4 crossbars 22. The left and right ends of the crossbars 22 are respectively provided with two second connecting plates 221 that are spaced apart in the vertical direction. The support column 1 is provided with a connecting base 13, and the connecting base 13 is hinged with two third connecting plates 14 in the vertical direction. Each third connecting plate 14 has two strip holes 15 on the left and right sides. The strip holes 15 on the same third connecting plate 14 are respectively movably connected to one end of different crossbars 22. A plurality of first connecting plates 23 are arranged at intervals along the vertical direction, and strip holes 15 are respectively opened at the four corners of the first connecting plates 23. The strip holes 15 of the same first connecting plate 23 are respectively movably connected to the other end of different crossbars 22. The third connecting rod 24 is used to fix the upper and lower adjacent crossbars 22. For any set of crossbars 22, the third connecting rod 24 passes through one second connecting plate 221, the strip hole 15 and another second connecting plate 221 from top to bottom. The third connecting plate 14 and the first connecting plate 23 are partially embedded in the gap between the second connecting plates 221. Through the connection of the third connecting rod 24, the upper and lower adjacent crossbars 22 can slide synchronously relative to the first connecting plate 23 and the third connecting plate 14 along the length direction of the strip hole 15, and / or rotate around the axis of the third connecting rod 24.

[0024] It should be noted that the crossbars 22 are divided into two groups, left and right, along the length of the folding cross brace 2, with four crossbars in each group. These crossbars are the main load-bearing components of the folding cross brace 2. The first connecting plates 23 are spaced apart vertically, with slotted holes 15 at their four corners for connecting one end of the crossbars 22 and providing a sliding track. The second connecting plate 221 can be two plates that extend horizontally from the left and right ends of the crossbars 22 and are spaced apart vertically, for connecting with the third connecting plate 14 and the first connecting plate 23. The connecting base 13 is located on the support column 1 and serves as the mounting fulcrum for the third connecting plate 14. The third connecting plates 14 are sequentially hinged to the connecting base 13 vertically. Each third connecting plate 14 has two slotted holes 15, and the slotted holes 15 on the same third connecting plate 14 are connected to different crossbars 22. The ends correspond to the movable connection; the strip hole 15 is opened on the third connecting plate 14 and the first connecting plate 23, providing a guide space for the crossbar 22 to slide and rotate along the length direction, which is the key structure to realize the movable connection; the third connecting rod 24 is used to fix the upper and lower adjacent crossbars 22, and passes through a second connecting plate 221, the strip hole 15 and another second connecting plate 221 from top to bottom, so that the upper and lower adjacent crossbars 22 can move synchronously; in one embodiment, the connection point 21 is located in the middle of the folding cross brace 2 and corresponds to the position of the first connecting plate 23, serving as the pivot center of the folding action and the fixed node of the pulling rope. The third connecting plate 14 and the first connecting plate 23 are partially embedded in the gap between the second connecting plate 221, which can increase the stability of the hinge connection between the folding cross brace 2 and the support column 1 and avoid damage by typhoons. The movable connection specifically refers to the third connecting rod 24 passing sequentially through the upper second connecting plate 221, the strip hole 15, and the lower second connecting plate 221, thereby forming a sliding and rotating fit between the end of the crossbar 22 and the third connecting plate 14 or the first connecting plate 23.

[0025] Understandably, starting from the original state of the gabion, when a typhoon acts on the gabion structure from one side, the folding cross brace 2 on the windward side bears the wind load first. At this time, the left and right sets of crossbars 22 of the folding cross brace 2 begin to move in coordination: the connection point 21 and the first connecting plate 23 move towards the center of the gabion. The movement of the first connecting plate 23 drives the third connecting rod 24, thereby pulling one end of the crossbar 22 towards the center of the gabion. During this process, the end of the crossbar 22 can slide along the length of the slot 15 and rotate around the axis of the third connecting rod 24, realizing a movable connection. As the wind force increases, the left and right sets of crossbars 22 move closer to each other, causing the folding cross brace 2 as a whole to converge towards the central connecting plate 5. The connection point 21, as the folding pivot center, moves inward (i.e., towards the central connecting plate 5), synchronously pulling... The tension cable drives the extension tube of the tensioner 41 to generate restoring force. During this movement, the third connecting rod 24 is fixedly connected to the adjacent horizontal bars 22. Through the coordinated displacement of the connection point 21 and the first connecting plate 23, the left and right horizontal bars 22 are guided to slide and rotate around the third connecting rod, so that the folded cross brace 2 on the windward side converges towards the center of the cage. This not only effectively absorbs and disperses some of the impact energy through the folding movement of the structure of the strip hole 15 and the horizontal bar 22, but also ensures the coordination and stability of the overall frame through the rigid synchronization of the upper and lower horizontal bars 22. At the same time, the movable connection method combining sliding and rotation at the end of the horizontal bar 22 gives the cage an adaptive adjustment capability, enabling it to cope with complex wind and wave loads of multiple directions and changes. This provides a reliable structural foundation for the entire cage to achieve efficient and flexible typhoon resistance performance.

[0026] Preferably, the tensioner 41 has a telescopic tube with a sealed cavity inside, the cavity is filled with gas at a preset pressure, and the outer end of the telescopic tube is connected to the tension rope.

[0027] Understandably, when external forces such as typhoons are applied to the cage, the folding cross brace 2 undergoes elastic deformation, causing the connection point 21 to shift. The pull rope simultaneously pulls the outer end of the telescopic tube inside the tensioner 41, causing the telescopic tube to change from a compressed state to an extended state. Due to the gas pressure inside the telescopic tube, a restoring force that resists the extension is generated. This restoring force is transmitted in the opposite direction to the connection point 21 through the pull rope, forming a resistance force opposite to the external force, thereby offsetting or weakening the deformation of the folding cross brace 2 and realizing the typhoon resistance function of the cage. By converting the limited deformation of the rigid structure into the storage and release of gas compression energy, the effect of dynamic buffering and self-stabilization is achieved.

[0028] Preferably, each of the folding cross braces 2 is provided with two connection points 21, and the two connection points 21 are respectively connected to the tensioners 41 on the first connecting rods 4 adjacent to each other on both sides of the folding cross brace 2 through two tension ropes.

[0029] It should be noted that each folding cross brace 2 has two connection points 21 (e.g., Figure 2 As shown, symmetrical force transmission is achieved through a two-point arrangement; two tension ropes are independently connected to the corresponding connection point 21 and the anti-tension device 41, forming a double-sided force transmission path; the first connecting rods 4 adjacent to each other on both sides of the folding cross brace 2 refer to two different first connecting rods 4 located on the left and right sides of the folding cross brace 2, and the anti-tension devices 41 on them are connected to the connection point 21 in a one-to-one correspondence, meaning that each connection point 21 establishes a unique correspondence only with the anti-tension device 41 on the first connecting rod 4 on its spatially adjacent side, ensuring the accuracy and independence of the force transmission path.

[0030] It is understandable that by setting two connection points 21 on each folding cross brace 2, when the cage is subjected to the force of a typhoon, the folding cross brace 2 undergoes elastic deformation, causing the two connection points 21 to shift and independently pull the corresponding two tension ropes, driving the anti-tensioners 41 on the first connecting rods 4 on both sides to respond synchronously, forming a balanced restoring force on both sides of the folding cross brace 2. This double-sided symmetrical force structure can effectively resist the bending deformation of the folding cross brace 2 and improve the overall wind resistance stability of the cage.

[0031] Preferably, the two connection points 21 are located in the middle of the folding cross brace 2 and are symmetrically distributed on the left and right.

[0032] It should be noted that the middle section refers to the central area along the length of the folding cross brace 2, which is the part of the structure where deformation is most significant under stress; for example... Figure 2 As shown, there are two connection points 21, which are symmetrically distributed on the left and right sides. This means that the two connection points 21 are located in the middle of the folding cross brace 2 and are symmetrically arranged in the horizontal direction to ensure balanced force and symmetrical force transmission path.

[0033] Understandably, when a typhoon acts on the cage from one side, the folding cross brace 2 undergoes elastic deformation, expanding or converging under wind load. The maximum deformation occurs in the central region of the structure. By placing the two connection points 21 in the middle and symmetrically distributed left and right, the fixing nodes of the tension ropes are precisely positioned at the most deformation-sensitive locations, enabling immediate detection of displacement changes and rapid response of the tensioners 41. Simultaneously, the symmetrical layout ensures that the two connection points 21 experience equal and symmetrical forces, respectively pulling the tensioners 41 on the adjacent first connecting rods 4 on both sides of the folding cross brace 2, generating a balanced restoring torque. This effectively avoids uneven stress and structural distortion caused by the offset of the connection points 21.

[0034] Preferably, there are two folding cross braces 2 between two adjacent support columns 1, and the two folding cross braces 2 are symmetrically and parallelly distributed vertically.

[0035] Specifically, the two folding cross braces 2 are symmetrically and parallelly distributed, so that the stiffness of the upper and lower mesh structures is the same. The symmetrical layout ensures that the wind load is evenly transmitted to the support column 1, avoiding excessive pressure on the support column 1 by a certain layer of mesh structure. At the same time, it ensures that the displacement of the connection point 21 of the upper and lower layers is coordinated, and that the tension rope and the anti-tensioner 41 respond in a consistent manner, avoiding interlayer misalignment and torsional instability.

[0036] Preferably, a second connecting rod 6 is vertically connected between the two symmetrically parallel folding cross braces 2, and the two ends of the second connecting rod 6 are respectively fixedly connected to the folding points of the two folding cross braces 2.

[0037] Understandably, the second connecting rod 6 rigidly connects the folding points (i.e., connection points 21) of the upper and lower folding cross braces 2. When a typhoon acts on the cage, the folding point of any one folding cross brace 2 will be displaced. This displacement is transmitted in real time to the folding point of the other folding cross brace 2 through the second connecting rod 6, causing the two folding cross braces 2 to deform synchronously and pull the corresponding tension ropes in coordination, driving the tensioner 41 to generate restoring force. This rigid linkage integrates the two independent folding cross braces 2 into a unified overall resistance unit, realizing the balanced distribution and coordinated response of forces between the layers, significantly improving the overall stiffness and deformation resistance of the cage, avoiding local damage or failure caused by the independent force of a single layer structure, and effectively enhancing the structural safety of the cage under extreme sea conditions.

[0038] Preferably, such as Figure 5 and Figure 6 As shown, the third connecting plate 14 includes a fourth connecting plate 16 arranged in a vertical direction. A guide wheel 42 is provided between the fourth connecting plates 16. The fourth connecting plate 16 has two strip holes 15 on the left and right sides, through which the third connecting rod 24 passes. Each of the first connecting rods 4 is provided with a guide wheel 42 at one end near the support column 1, and the pull rope passes over the guide wheel 42 between the fourth connecting plates 16 and the guide wheel 42 on the first connecting rod 4.

[0039] It should be noted that the fourth connecting plate 16 is arranged vertically between the third connecting plates 14, serving as the mounting base for the guide wheel 42; the guide wheel 42 is respectively arranged between the fourth connecting plates 16 and at the end of the first connecting rod 4 near the support column 1, serving as the steering and guiding components of the pull rope, used to change the direction of force transmission and reduce frictional resistance; the fourth connecting plate 16 has two strip holes 15 on the left and right sides, providing a passage for the third connecting rod 24 to pass through, which can be combined with the third connecting plate 14 to reinforce the hinge between the folding cross brace 2 and the support column 1; one end of the pull rope is connected to the connection point 21 on the folding cross brace 2, and the other end is connected to the anti-tensioner 41, and passes around the corresponding guide wheel 42, i.e. Figure 5As shown, the tension rope turns for the first time by passing around the guide wheel 42 between the fourth connecting plates 16, then turns for the second time by passing around the guide wheel 42 at the end of the first connecting rod 4, and finally connects to the tensioner 41.

[0040] Preferably, the support column 1 is provided with a lifting rack 11, and the support column 1 includes a lifting member 12 that can move up and down along the lifting rack 11. The connecting base 13 is provided on the lifting member 12, and the first connecting rod 4 is hinged to the lifting member 12.

[0041] It should be noted that the support columns 1 are arranged vertically and circumferentially to enclose the internal space, serving as the main vertical load-bearing components of the cage; the lifting rack 11 is provided on the support column 1 to provide vertical guidance and positioning track for the lifting component 12, wherein the lifting component 12 can be a device that can be remotely controlled for lifting or a device that can be manually driven for lifting; the lifting component 12 can move up and down along the lifting rack 11, driving the components connected to it to move up and down as a whole; the connecting base 13 is provided on the lifting component 12 as the mounting fulcrum of the third connecting plate 14; the first connecting rods 4 are all hinged to the lifting component 12, forming the radial overall support frame of the cage.

[0042] Understandably, by setting a lifting rack 11 and a lifting component 12 on the support column 1, the net cage gains the ability to adjust its height in the vertical direction. When external forces such as typhoons are applied to the net cage, the lifting component 12 can move up and down along the lifting rack 11, causing the connecting base 13, the third connecting plate 14, the folding cross brace 2, the first connecting rod 4, and the central connecting plate 5 to move up and down as a whole. This changes the immersion depth and the position of the force center of the net cage, enabling the net cage to dynamically adjust its own posture according to the typhoon intensity and sea state changes, optimize its wind resistance performance, and improve its environmental adaptability.

[0043] Preferably, such as Figure 2 As shown, a fourth connecting rod 25 is vertically fixed between the two first connecting plates 23 of the same folding cross brace 2; The two connection points are located on the fourth connecting rod and are symmetrically distributed on the left and right.

[0044] It should be noted that the fourth connecting rod 25 is fixedly connected between the two first connecting plates 23 of the same folding cross brace 2, serving as a structural reinforcement to enhance the overall rigidity and deformation resistance of the folding cross brace 2; the connection point 21 is a point set on the fourth connecting rod 25, serving as the pivot center of the folding action and the force transmission hub, shifting with deformation and synchronously driving the pulling rope action; the fixed connection means that the fourth connecting rod 25 and the first connecting plate 23 form a rigid connection, and relative displacement is not allowed. The two symmetrically distributed connection points 21 are symmetrically arranged on the fourth connecting rod 25 along the horizontal direction to ensure balanced force and symmetrical force transmission path.

[0045] Understandably, the fourth connecting rod 25 rigidly connects the two first connecting plates 23 of the same folding cross brace 2 into a whole. When a typhoon acts on the cage, the crossbar 22 of the folding cross brace 2 slides and rotates under the restriction of the strip hole 15. At this time, the fourth connecting rod 25 effectively constrains the relative displacement between the two first connecting plates 23, thereby effectively increasing the overall structural stability of the folding cross brace 2. The symmetrical distribution on the left and right ensures that the two connection points 21 are subjected to equal forces and opposite symmetrical directions, respectively pulling the anti-tensioners 41 on the adjacent first connecting rods 4 on both sides of the folding cross brace 2, generating an effective restoring force to resist the bending deformation of the folding cross brace 2.

Claims

1. A typhoon-resistant cage, characterized in that, It includes several support columns and two layers of net structure. Each layer of net structure includes several folded cross braces, several tension ropes, several first connecting rods and a central connecting plate. The first connecting rods are equipped with anti-tensioners. Several of the support columns are arranged vertically and circumferentially, and several of the folding cross braces are provided between two adjacent support columns. The two ends of the folding cross braces are respectively hinged to the two adjacent support columns. The several support columns and several of the folding cross braces enclose an internal space. The two central connecting plates are respectively set at the top and bottom of the cage, and a number of first connecting rods are radiating along the central connecting plates. One end of the first connecting rod is connected to the central connecting plate, and the other end is perpendicularly connected to the support column. The folding point of the folding cross brace is the connection point. One end of the traction rope is connected to the connection point on the folding cross brace, and the other end is connected to the corresponding anti-tensioner. When the cage is subjected to a force, the folding cross brace undergoes expansion or contraction deformation. The connection point is displaced with the deformation and simultaneously pulls the corresponding tension rope to generate tension against the tensioner. This drives the corresponding anti-tensioner to generate a restoring force that resists the tension. The restoring force acts in the opposite direction on the connection point through the tension rope to resist the deformation of the folding cross brace.

2. The typhoon-resistant gabion cage according to claim 1, characterized in that, The folding cross brace includes several crossbars and several first connecting plates. The crossbars are divided into two groups, left and right, along the length of the folding cross brace. Each group includes four crossbars. The left and right ends of the crossbars are respectively provided with two second connecting plates that are spaced apart in the vertical direction. The support column is provided with a connecting base, and the connecting base is hinged with two third connecting plates in the vertical direction. Each third connecting plate has two strip holes on the left and right sides. The strip holes on the same third connecting plate are movably connected to one end of different crossbars respectively. A plurality of first connecting plates are arranged at intervals along the vertical direction, and each of the four corners of the first connecting plate has a strip hole. The strip hole of the same first connecting plate is movably connected to the other end of different crossbars. The upper and lower adjacent crossbars are fixedly connected by a third connecting rod. For any set of crossbars, the third connecting rod passes through a second connecting plate, the strip hole and another second connecting plate from top to bottom in sequence. The third connecting plate and the first connecting plate are partially embedded in the gap between the second connecting plates. Through the connection of the third connecting rod, the upper and lower adjacent crossbars can slide synchronously relative to the first connecting plate and the third connecting plate along the length direction of the strip hole, and / or rotate around the axis of the third connecting rod.
