Description

Technical Field

[0001] The present invention relates to the technical field of marine aquaculture. Background Art

[0002] Large-scale fence aquaculture is one of the important deep-sea aquaculture models that have been actively explored in China in recent years. It has the characteristics of a wide aquaculture area, a large space for fish activities, a more natural aquaculture environment, and a more ecological quality of cultured fish. It is more suitable for the waters with a gentle continental shelf trend in China and the cultivation of various unique economic fish species in China.

[0003] Since the netting is placed in seawater for a long time, it is easily attached by organisms such as algae and shellfish, blocking the mesh, affecting the exchange of internal and external water bodies, increasing the pressure on the netting, and causing damage to the netting. Therefore, the netting needs to be replaced at any time according to the actual situation. The traditional method of manually replacing the netting requires divers to hang the net underwater, which has a large labor intensity, low work efficiency, and there are safety risks.

[0004] In addition, at present, the netting of the column pile type aquaculture fence is mainly realized by burying the netting into the bottom mud to a certain depth or using heavy objects to press the edge of the netting on the seabed. Both of these operation methods have potential safety hazards. Under the long-term scouring action of water flow, pits will be generated at the bottom of the netting or the netting will shift, causing the cultured fish to escape from the bottom and resulting in heavy losses. Summary of the Invention

[0005] In order to solve the above problems existing in the existing deep-sea aquaculture fence, the present invention provides a pile column type fence for deep-sea aquaculture.

[0006] The technical solution adopted by the present invention to achieve the above object is: a pile column type fence for deep-sea aquaculture, including vertical piles 2 on both sides and a netting 3 located between the vertical piles 2. Slideways 6 are longitudinally installed on the two vertical piles 2, and net clip pieces 9 are slidably installed in the slideways 6. The net clip pieces 9 on the two vertical piles 2 are respectively connected to the net ropes 10 at both edges of the netting 3.

The long rod 20 and the short rod 21 are vertically arranged. Two elastic clip pieces 22 are installed at positions opposite to the long rod 20 and the short rod 21 on the other side of the arc groove 19. The lengths of the long rod 20 and the short rod 21 are greater than the width of the arc groove 19. The length of the short rod 21 is less than the length of the long rod 20. The edge of the front end contact of the short rod 21 overlaps the edge of the arc groove 19. The front end contact of the short rod 21 is an elastic structure. Arc-shaped protrusions 14 are relatively arranged on the upper parts of the inner sides of the two elastic clip pieces 22. The minimum distance at the arc-shaped protrusions 14 between the two elastic clip pieces 22 is less than the horizontal width of the long rod 20. The distance between the two elastic clip pieces 22 is greater than the horizontal width of the long rod 20.

[0011] The inner side of the front end contact of the short rod 21 is connected to the bottom of the inner groove of the short rod 21 through a spring.

[0012] A pile cap 1 is installed at the upper end of the vertical pile 2. A truss 25 is installed on the pile cap 1. A steering fixed pulley 24 is installed on the truss 25.

[0030] As Figure 1 shown, the pile column type fence for deep - sea aquaculture of the present invention mainly includes three parts: an upright pile 2, a netting 3 and a base 4.

[0031] The upright pile 2 is deeply buried in the seabed. A plurality of hoop rings 5 are longitudinally installed on the upright pile 2. Hoop clamps 27 are provided on both sides of the hoop ring 5. Connecting rods 7 are inserted through the plurality of hoop clamps 27 on the same side, as Figure 2 shown. As Figure 3 andFigure 4 As shown, the slideway 6 is fixed on the connecting rod 7 through the slideway clamp 8 at its rear side. Connecting rods 7 and slideways 6 are provided on both sides of each vertical pile 2, so that multiple sets of fishing nets 3 can be combined and connected for use as needed.

[0032] Net clip pieces 9 are placed in the slideway 6. A lifting rope groove 28 is arranged on the inner side of the net clip piece 9 to provide a moving space for the lifting rope 13. The outer side clamping buckle 11 clamps the net rope 10 on the side edge of the fishing net 3 to realize the connection of the side part of the fishing net 3. As Figures 5-7 shown, a suitable number of net clip pieces 9 form a group. Each group of net clip pieces 9 is fixed up and down on the sleeve rod 12. The distance and group distance are controlled by the sleeve rod 12 to participate in the lifting operation of the fishing net 3. Before the fishing net 3 is put into the water, the net clip pieces 9 are fixed on the net rope 10 on the side edge of the fishing net 3 through the clamping buckles 11 in advance. The number of groups of net clip pieces 9 and the number of single-group net clip pieces in the slideway 6 are determined according to the specific height of the fishing net 3. The connecting sleeve rod 12 determines the distance and group distance of the net clip pieces 9 to ensure that the total height of all net clip pieces 9 and the sleeve rod 12 is approximately equal to the height of the fishing net 3. When the lifting rod 17 descends, under the traction of the net rope 10, the net clip pieces 9 will be lowered along the slideway 6 in groups. When the lifting rod 17 enters the arc groove 19, the net clip pieces 9 and the sleeve rod 12 evenly cover the slideway 6. When the fishing net 3 rises, the lifting rod 17 is lifted by the lifting rope 13 to push the net clip pieces 9 to move up along the slideway 6, and the net clip pieces 9 can be recovered at the entrance of the slideway 6. Grouping the net clip pieces 9 facilitates the recovery and lowering of the net clip pieces 9 during the lifting process and improves work efficiency.

[0033] As Figure 8 shown, the base 4 is placed between two adjacent vertical piles 2 and is fixed in position through the fixed legs 15, and the bottom net 16 is arranged at the lower end. The fixed legs 15 use the deep-sea bottom soil as the bearing soil of the base, eliminating the influence of the unevenness of the seabed surface caused by the scouring and transportation of the seabed surface soil by water flow on the stability of the base 4, avoiding the occurrence of uneven settlement or local inclination of the structure, and being able to adapt to the complex marine environment in the deep and far sea. The bottom net 16 belongs to a rigid net and should be inserted into the surface soil to a certain depth to avoid the escape of the bottom of the aquaculture products and improve the tightness of the structure.

[0034] The lifting rod 17 belongs to a rigid rod and is located at the lower edge of the fishing net 3. The rod end of the lifting rod 17 is connected to the lifting rope 13 to perform the lifting operation of the fishing net. The lifting rod 17 is located in the arc groove 19 at the upper part of the base 4. When the fishing net 3 needs to be replaced, the lifting rod 17 is lifted to the water surface for fishing net replacement work. As Figure 9As shown, the arc groove 19 is located at the upper part of the base 4 and is used to place the structure lifting rod 17. The lifting rod 17 is connected to the lower edge of the netting 3. Its main body is a long cylindrical rod, and the ends are chamfered cubes, which are convenient for moving in the slideway 6. The ends are connected to the lifting ropes 13. The rotating feet 18 are staggeredly distributed on both sides of the arc groove 19 and are used to control the locking and release of the lifting rod 17. When the netting 3 needs to be lowered for work, the lifting rod 17 drives the netting 3 to descend along the chute 6 into the arc groove 19, triggering the rotating feet 18 to close and locking the lifting rod 17 in the arc groove 19. When the netting needs to be raised for net replacement, the lifting rope 13 drives the lifting rod 17 to rise, triggering the rotating feet 18 to open and releasing the lifting rod 17 to complete the net raising work.

[0035] The rotating feet 18 are longitudinally staggered along the arc groove 19 on both sides of the arc groove 19 according to a reasonable quantity. The rotating feet are composed of an arc-shaped long rod 20, a telescopic short rod 21 and a rotating shaft 23, and a pair of elastic clips 22 are arranged oppositely. The length of the long rod 20 is greater than the width of the arc groove of the arc groove 19, and the length of the short rod is slightly greater than the width of the arc groove 19, so that the arc edge of the front contact head just rests on the edge of the arc groove 19 to prevent the short rod 21 from freely rotating. The inner side of the contact head is connected to the bottom of the inner groove of the short rod 21 through a spring and can elastically expand and contract. The upper edge part of the inner side of the elastic clip 22 is an arc-shaped protrusion 14, and the minimum distance at the arc-shaped protrusion 14 between the two elastic clips 22 is slightly less than the transverse width of the long rod 20; the distance between the elastic clips 22 is slightly greater than the transverse width of the long rod 20.

[0036] When the lifting rod 17 is not lowered, the rotating feet remain open, as Figure 10As shown in the figure. When the lifting rod 17 descends to the upper part of the base 4, the short rod 21 begins to bear the gravity of the lifting rod 17, increasing the supporting force of the edge of the arc groove 19 on the arc edge of the front contact of the short rod 21. Due to the elastic telescopic property of the front contact, the component force of the supporting force along the longitudinal direction of the short rod 21 will cause the front contact to elastically contract, shortening the length of the short rod 21. When the length is exactly equal to the groove pitch, the rotating catch 18 rotates, and the lifting rod 17 follows the rotation of the rotating catch 18 and drops into the arc groove 19. The groove belly radius below the rotating catch 18 is much larger than that in other areas, so that after the short rod turns past the edge of the arc groove 19, the front contact resumes its original length under the elastic action of the spring. At this time, the short rod 21 bears the lateral supporting force generated by the gravity component of the lifting rod 17 and rotates to the vertical position under the action of the lateral supporting force; the long rod 20 is connected to the short rod 21 at a 90° angle and rotates synchronously with the short rod 21. After the short rod 21 turns past the edge of the arc groove 19, the long rod 20 begins to contact the arc protrusion 14 of the elastic clip 22. Since the rotating catch 18 still bears the lateral supporting force generated by the gravity component of the lifting rod 17 at this time, the long rod 20 presses the arc protrusion 14 at the upper end of the elastic clip 22, forcing the elastic clip 22 to elastically deform. After the long rod 20 bypasses the arc protrusion 14, due to the increased movement space, the extrusion on the elastic clip 22 is released, and the elastic deformation of the elastic clip 22 is restored. The long rod 20 rotates to the horizontal position with the short rod 21. The rotating catch 18 is in a closed state at this time, as shown in Figure 11 shown in the figure. Due to the elastic constraint of the elastic clip 22 on the long rod 20, the rotating catch can maintain the closed state.

[0037] When the fishing net 3 needs to be lifted and replaced, the lifting rope 13 starts to lift the lifting rod 17 located in the arc groove 19. Due to the upward traction force of the lifting rope 13 on the lifting rod 17, an upward pressure will be generated on the long rod 20, forcing the long rod 20 to press the arc protrusion 14 at the upper part of the elastic clip 22, causing the elastic clip 22 to elastically deform. After the long rod 20 bypasses the arc protrusion 14 upward, due to the lateral supporting force caused by the traction force of the lifting rod 17, the long rod 20 will continue to rotate to the vertical position until the constraint relationship with the lifting rod 17 is completely released, and the lifting rod 17 can be freely lifted. The short rod 21 rotates with the long rod 20. After the long rod 20 bypasses the arc protrusion 14, the short rod 21 will contact the edge of the arc groove 19. Under the action of the traction force, the supporting force between the short rod 21 and the edge of the arc groove 19 increases. Due to the elastic telescopic property of the front contact of the short rod 21, the component force of the supporting force along the longitudinal direction of the short rod 21 will cause the front contact to elastically contract, shortening the length of the short rod 21. When the length is exactly equal to the groove pitch, the short rod 21 rotates. After turning past the edge of the arc groove 19, the supporting force between the short rod 21 and the edge of the arc groove 19 decreases, and the front contact resumes its original length, preventing the short rod 21 from freely rotating and maintaining the open state of the rotating catch 18. The rotating catch (18) mechanically controls the locking and release of the lifting rod 17.

[0038] The pile cap 1 is located at the upper part of the vertical pile 2, and a steering fixed pulley 24 is installed thereon. As Figure 12 shown, the steering fixed pulley 24 is directly above the slideway opening and is fixed to the pile cap 1 through a truss 25. Its main function is to change the vertical lifting direction of the lifting rope 13 into a horizontal lifting direction and connect it to the rear winch 26. The winch 26 is located behind the steering fixed pulley 24, and the lifting rope 13 is wound around the winch 26. The winch 26 contains a motor, and by controlling the rotation of the winch, the lifting and lowering of the lifting rod 17 are realized.
