DETAILED DESCRIPTION

[0028] Reference herein to an embodiment means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of one another. As will be apparent to those of ordinary skill in the art, embodiments described herein can be combinable with other embodiments.

[0029] Embodiment: A net cage with wave-damping function and lifting function, comprising Figures 1-3 As shown, comprising: crossbeam 101, which adopts a rectangular frame structure and is provided with two layers; diagonal brace 102, which is fixedly installed between each crossbeam 101 and the two layers of crossbeams 101, thereby forming a net-shaped surface for providing structural stability and reducing wave energy; six groups of piles 103, which are fixedly installed vertically below crossbeams 101 and symmetrically arranged at the four edges of crossbeams 101, with four groups being located at the corner positions; pile leg 104, which is slidingly installed at the bottom of pile 103 and used for insertion into the seabed for fixation; control rod 105, which is rotatably installed in each pile 103 and cooperates with pile leg 104 through a helical groove, and the rotary motion of control rod 105 is converted into the relative displacement between pile 103 and pile leg 104; mounting shell 106, which is fixedly installed on crossbeam 101; synchronous wheel 107, which is fixedly installed on the shaft of each control rod 105; synchronous belt 108, which is wound between all synchronous wheels 107 and cooperates with synchronous wheels 107 through a tooth groove to achieve power transmission; drive motor 109, which is fixedly installed at the top of mounting shell 106 and has an output end connected with one of control rods 105 to provide rotary driving force.

[0030] In application, the net cage is fixed to the seabed through pile leg 104 and forms a rigid protective barrier around the periphery of the breeding unit, and the specific arrangement form is shown in Figure 10When impacted by sea waves, the mesh surface formed by the crossbeam 101 and the diagonal braces 102 resists the initial impact of the waves with its overall rigidity, and through the dense arrangement of the diagonal braces 102, achieves the effect of interference and diversion, effectively breaking, dissipating and reducing the wave energy, thereby significantly reducing the wave intensity transmitted to the area where the internal aquaculture unit is located.

[0031] In addition, the net cage has a high degree of active adjustment function: after starting the driving motor 109, all control rods 105 are synchronously controlled to rotate forward and backward through the transmission structure of the synchronous belt 108 and the synchronous wheel 107, and the rotary motion is converted into the lifting displacement of the leg 104 relative to the pile 103 through the screw groove, thereby driving the overall height adjustment of the mesh surface formed by the crossbeam 101 and the diagonal braces 102; based on this function, the net cage can be adjusted in linkage when the tide changes, ensuring that the wave dissipation working surface is always at an optimal height of two meters above the water surface to cope with wave impact under different tidal conditions and continuously maintain the wave resistance effect.

[0032] Compared with the prior art, the structure of the net cage can solve the defects of weak wave resistance of the traditional aquaculture unit and easy damage in strong wave environment - through the wave energy dissipation effect of the overall rigid structure and the mesh surface of the diagonal braces 102, the wave force transmitted to the aquaculture unit is reduced, not only enhancing the stability and safety of the aquaculture unit, but also prolonging its service life in complex marine environment; combined with the linkage adjustment function of the mesh surface height with the tide, the wave dissipation structure of the net cage is always in the best working position, further improving the adaptability and buffering effect in severe sea conditions.

[0033] In combination with Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7 , it further comprises: four groups of connecting structures, respectively arranged at the four corner positions of the crossbeam 101, for connecting the multiple net cages arranged in a ring to form a whole, improving the stability of the entire protective structure; The connecting structure comprises: a first mounting frame 201 fixedly installed on the crossbeam 101; a second mounting frame 202 provided on the first mounting frame 201; a driving electric cylinder 203 fixedly installed in the second mounting frame 202; three groups of hooking pieces uniformly arranged on the second mounting frame 202, connected with the driving electric cylinder 203 and controlled to act by the driving electric cylinder 203, and uniformly transmitting the acting force through the three groups of hooking pieces to improve the connection stability and effect; The hooking piece comprises a control seat 204, which is slidingly installed in the second mounting frame 202, fixedly connected with the output end of the driving cylinder 203, and driven by the driving cylinder 203 to reciprocate; a connecting seat 205, which is slidingly installed on the driving cylinder 203 and passes through the control seat 204 to contact and cooperate with the control seat 204; a connecting spring 206, which is sleeved on the sliding shaft of the connecting seat 205 and fixed at both ends of the connecting seat 205 and the driving cylinder 203; a hook claw 207, which is rotationally installed on the connecting seat 205 and adopts a C-shaped structure; a top shaft 208, which is slidingly installed on the connecting seat 205 and contacts a slope provided in the control seat 204; a first inserting shaft 209, which is slidingly installed on the top shaft 208 and is inserted into a hole provided on the hook claw 207 in a plug-in manner; a first reset spring 210, which is fixedly installed between the top shaft 208 and the connecting seat 205; and a second reset spring 211, which is fixedly installed between the top shaft 208 and the first inserting shaft 209, wherein the elastic coefficient of the first reset spring 210 is greater than that of the second reset spring 211.

[0034] When the net cage is installed in place in the sea, at this time, the connecting structures on the opposite sides of the adjacent two net cages are close to each other; then, the driving cylinder 203 is started to drive the control seat 204 to move towards the opposite direction, the control seat 204 first contacts the connecting seat 205, and the connecting seat 205 extrudes the top shaft 208 to move downward through the slope, at this time, the first inserting shaft 209 abuts against the surface of the hook claw 207 without being inserted into the hole, and the first reset spring 210 and the second reset spring 211 are compressed; then, the control seat 204 drives the connecting seat 205 to move together, the connecting spring 206 is stretched, the hook claws 207 on the two net cages contact each other and rotate to hook each other under the pushing action, when the hook claws 207 rotate to the position where the hole and the first inserting shaft 209 are aligned, the second reset spring 211 releases the deformation to push the first inserting shaft 209 to be inserted into the hole to be locked, thereby enhancing the strength and stability of the connection between the two net cages, so that the whole net cages work cooperatively to resist the waves.

[0035] When the net cage is installed in place in the sea, at this time, the connecting structures on the opposite sides of the adjacent two net cages are close to each other; then, the driving cylinder 203 is started to drive the control seat 204 to move towards the opposite direction, the control seat 204 first contacts the connecting seat 205, and the connecting seat 205 extrudes the top shaft 208 to move downward through the slope, at this time, the first inserting shaft 209 abuts against the surface of the hook claw 207 without being inserted into the hole, and the first reset spring 210 and the second reset spring 211 are compressed; then, the control seat 204 drives the connecting seat 205 to move together, the connecting spring 206 is stretched, the hook claws 207 on the two net cages contact each other and rotate to hook each other under the pushing action, when the hook claws 207 rotate to the position where the hole and the first inserting shaft 209 are aligned, the second reset spring 211 releases the deformation to push the first inserting shaft 209 to be inserted into the hole to be locked, thereby enhancing the strength and stability of the connection between the two net cages, so that the whole net cages work cooperatively to resist the waves.

[0036] The net cage is provided with the automatically interlocked connecting structure to improve the connection strength between the net cages and enhance the overall stability, which mainly comprises the uniform force exertion of the multiple hooking pieces and the cooperative locking mechanism of the top shaft 208 and the slope of the control seat 204, thereby improving the reliability and stability of the connection between the net cages, so that the whole net cages work cooperatively to resist the waves under the wave load, enhance the overall wave resistance, and prolong the service life of the structure.

[0037] In combination with Figure 8As shown, the net cage further comprises an adapting structure arranged between the first mounting frame 201 and the second mounting frame 202, which is used to realize flexible connection between the net cages, so as to improve the impact resistance of the overall structure. The adapting structure comprises a first connecting shaft 301 fixedly installed in the first mounting frame 201, a connecting head 302 movably installed on the first connecting shaft 301, which can move up and down and rotate around the first connecting shaft 301, a first adapting spring 303 sleeved on the first connecting shaft 301, both ends of which are fixed on the first connecting shaft 301 and the connecting head 302 respectively, an adapting torsional spring 304 fixedly installed between the connecting head 302 and the first connecting shaft 301 and arranged in the connecting head 302, a second connecting shaft 305 fixedly installed on the connecting head 302, and the second mounting frame 202 is slidably installed on the connecting head 302 through the second connecting shaft 305, and a second adapting spring 306 sleeved on the second connecting shaft 305, both ends of which are fixed on the second mounting frame 202 and the connecting head 302 respectively.

[0038] When the net cage is impacted by waves, the impact force will be transmitted to the adapting structure through the second mounting frame 202, in the process, the first adapting spring 303 absorbs the longitudinal impact energy by compression or stretching, the second adapting spring 306 absorbs the transverse impact energy, and the connecting head 302 rotates around the first connecting shaft 301 to absorb the torsional force through the adapting torsional spring 304.

[0039] Therefore, through the synergistic effect of the multidirectional spring and the torsional spring in the adapting structure, the net cage realizes multidirectional displacement compensation, effectively disperses and buffers the impact force in each direction, so as to endow the connection part between the net cages with good flexibility and self-adaptive ability, avoid stress concentration caused by rigid connection, relieve the instantaneous stress peak caused by wave impact, significantly improve the durability and safety margin of the overall structure in severe sea conditions, protect the connection structure and maintain the stable connection between the net cages.

[0040] In combination with Figure 1 and Figure 9 As shown, the net cage further comprises a locking structure arranged between the first mounting frame 201 and the second mounting frame 202, which is used to lock the position of the second mounting frame 202 when the net cages are docked, so as to improve the accuracy of the docking of the connection structure. The locking structure comprises a bracket 401 fixedly installed on the first mounting frame 201, a rail seat 402 fixedly installed on the second mounting frame 202, a second inserting shaft 403 slidably installed on the bracket 401, which will form an inserting type cooperation with the insertion hole arranged on the second mounting frame 202, a third reset spring 404 sleeved on the second inserting shaft 403, both ends of which are fixed between the second inserting shaft 403 and the bracket 401 respectively, and a ball 405 rotating on the contact surface between the second inserting shaft 403 and the rail seat 402, which is used to improve the smoothness of the movement cooperation.

[0041] Before the abutting of the adjacent net cages, the connecting structure is in a natural state without action, at this time, the adjusting structure keeps the second mounting frame 202 in the initial position of flatness, in this state, the second inserting shaft 403 is inserted into the insertion hole of the second mounting frame 202 under the action of the third reset spring 404, and the relative position between the second mounting frame 202 and the first mounting frame 201 is locked, so as to assist the accurate positioning of the connecting structure between the adjacent net cages, and to create conditions for rapid abutting. When the connecting structure starts to perform the abutting action, the control seat 204 is displaced under the driving of the driving cylinder 203, and in the movement process, the second inserting shaft 403 is extruded, so that it overcomes the force of the third reset spring 404 and is separated from the insertion hole of the second mounting frame 202, and the locking of the second mounting frame 202 is released. Thereafter, the adjusting structure restores its flexible connection function, and allows the connecting structure to adapt to the position change during the abutting process. During the period when the connecting structure is in the flexible connection state, the second inserting shaft 403 always slides along the surface of the rail seat 402. Therefore, when the connecting structure is disconnected and the adjusting structure drives the second mounting frame 202 to restore the initial state, the second inserting shaft 403 can be quickly and accurately reinserted into the insertion hole of the second mounting frame 202, realizing the automatic recombination of the locking structure, and ensuring that the net cage has good repeated abutting precision and operation convenience.

[0042] In summary, through the automatic plug-in mechanism of the locking structure, the net cage effectively avoids the positioning deviation and connection loosening problem of the connecting structure during the abutting process, and improves the connection convenience and overall structural coordination between multiple net cages.

[0043] In combination Figure 1 As shown in the drawings, it further comprises: a photovoltaic panel 501 fixedly installed on the top of the installation shell 106, for converting light energy into electrical energy; a power storage module 502 fixedly installed on the installation shell 106, electrically connected with the photovoltaic panel 501, for storing electrical energy, and electrically connected with the driving motor 109 and the driving cylinder 203, for stably supplying power to them, so as to realize self-sufficiency of energy; and a signal lamp 503 fixedly installed on the installation shell 106, for indicating the position of the net cage at night or under low-visibility conditions, and increasing the visual prompt to ensure the reliability and safety of the application of the net cage in the actual sea area.

[0044] The application further provides a use method of the net cage with wave-eliminating function and lifting function, and the specific steps are as follows: S1. According to the hydrological conditions and wave characteristics of the sea area, the arrangement size, the enclosed range and the orientation of the mouth of the net cage are reasonably planned, and the mouth should avoid the dominant wave direction, so as to ensure the safety of the operation of the ship in and out of the aquaculture water area. S2, the net cage is transported to the target sea area, and the leg 104 is inserted into the seabed; the driving motor 109 is started, the control rod 105 is driven to rotate through the synchronous belt 108-synchronous wheel 107 structure, the net surface of the net cage is controlled to rise to a set height of more than two meters above the water surface, and the initial attitude adjustment is completed; S3, the driving cylinder 203 is started, the connection structures of adjacent net cages are close to each other, the interlocking is completed by the control seat 204 pushing the hooking part, and the second insertion shaft 403 is extruded to separate from the second installation frame 202, so that the constraint of the locking structure on the second installation frame 202 is released; at this time, the adjustment structure plays a flexible connection role, so that the net cage group forms a whole and has impact resistance; S4, according to the area of the enclosed water area, the flow field characteristics and the breeding density, the breeding unit is reasonably arranged in the protection range of the net cage to form a complete breeding and protection integrated structure; S5, in the operation process, according to the change of tidal level and wave condition, the height of the net surface of the net cage is adjusted in time, so that the net surface is always at the best wave dissipation height of more than two meters above the sea surface; before adjustment or when the net cage needs to be disassembled and reassembled, the driving cylinder 203 is operated in reverse, the hooking part is separated, the locking structure is automatically reset, and rapid disassembly is realized.
