Description

TECHNICAL FIELD

[0001] The present application relates to the field of rope manufacturing, more particularly, it relates to a high-strength net rope for deep-sea aquaculture net cages and a processing technology. BACKGROUND

[0002] Rope generally refers to a strip-shaped object twisted by two or more cotton, hemp, palm fiber or metal wire, and rope is widely used in various fields of life.

[0003] In existing use, there are situations that require the rope to be cut off, and the rope body at the cutting position is easy to scatter after the rope is cut off, which affects the strength of the rope, and needs to be improved. SUMMARY

[0004] In order to improve the problem that the rope body is easy to scatter after the rope is cut off, the present application provides a high-strength net rope for deep-sea aquaculture net cages and a processing technology.

[0005] The present application provides a high-strength net rope for deep-sea aquaculture net cages and a processing technology, which adopts the following technical scheme:

[0006] A high-strength net rope for deep-sea aquaculture net cages, comprising a rope body, the rope body comprising a rope core and a rope body, the rope body being arranged around the rope core, one end of the rope body being provided with a limiting sleeve, the limiting sleeve being provided with a limiting groove and a clamping groove, the limiting groove being used for embedding the rope core, and the clamping groove being used for embedding the rope body.

[0007] Through the above technical scheme, in actual use, the rope body is twisted by the rope core around the rope body, and after the rope body needs to be cut off, the rope body at the cutting position is easy to scatter, which causes the rope body and the rope core to separate, affecting the normal use of the rope body and the structural strength of the rope body. Therefore, the limiting sleeve is provided, the limiting groove of the limiting sleeve is used for embedding the rope core, and the clamping groove is used for embedding the rope body. The limiting of the rope core and the rope body by the limiting sleeve reduces the scattering of the rope body, and facilitates the use of the rope body.

[0008] Further, the rope body is an ultra-high molecular polyethylene cable, and the rope core is a metal wire.

[0009] Through the above technical scheme, the ultra-high molecular weight polyethylene cable has the advantages of high strength, small density, non-water absorption, low elongation, resistance to ultraviolet aging and strong resistance to seawater corrosion, and the strength is 12-16 times that of steel wire, which is cost-effective. The metal wire is used to further improve the overall structural strength.

[0010] Further, the slot of the limiting groove is consistent with the slot of the clamping groove, the limiting sleeve is provided with a sliding hole, the sliding hole is communicated with the limiting groove and the clamping groove, the sliding hole wall is provided with a sliding block, the sliding block is provided with an inclined surface one, and the inclined surface one is used for abutting against the core; when the core is embedded in the limiting groove and the rope body is embedded in the clamping groove, the core abutting against the inclined surface one of the sliding block makes the sliding block move away from the axis of the limiting sleeve, the sliding block moves and pushes the rope body to abut against the clamping groove wall.

[0011] Through the above technical scheme, in actual use, after the rope body is cut, the rope body near the cutting position is straightened and embedded in the clamping groove, then the limiting sleeve is moved to make the core embedded in the limiting groove and push the sliding block to move to abut against the rope body, and in this way, the situation that the rope body is separated from the clamping groove is reduced.

[0012] Further, the core is provided with a limiting part, the limiting part includes a plurality of strip-shaped grooves, the strip-shaped grooves are distributed along the circumference of the core, the strip-shaped grooves are embedded with the sliding block, and the limiting part is provided with a plurality of groups along the axis direction of the core; when the sliding block abuts against the groove bottom of the strip-shaped groove, the end of the sliding block away from the groove bottom of the strip-shaped groove abuts against the rope body.

[0013] Through the above technical scheme, the strip-shaped groove is provided, the sliding block is embedded in the strip-shaped groove, the core is limited by abutting against the sliding block through the strip-shaped groove wall, the situation that the core is separated from the limiting sleeve is reduced, when the sliding block abuts against the groove bottom of the strip-shaped groove, the end of the sliding block away from the groove bottom of the strip-shaped groove abuts against the rope body, the situation that the rope body is separated from the clamping groove is reduced, and the limiting effect on the rope body is improved.

[0014] Further, the groove bottom of the limiting groove is provided with a limiting spring, the end of the limiting spring away from the groove bottom of the limiting groove is connected with a separation part, the elastic force of the limiting spring limits the separation part to move towards the direction close to the groove bottom of the limiting groove; when the core abuts against the groove bottom of the limiting groove, the separation part abuts against the groove bottom of the strip-shaped groove, when the rope body moves away from the groove bottom of the limiting groove, the groove wall of the strip-shaped groove abuts against the separation part to make the separation part move away from the groove bottom of the limiting groove and abut against the sliding block to make the sliding block move away from the axis of the limiting sleeve, the rope body is continuously moved away from the groove bottom of the limiting groove, the separation part is separated from the strip-shaped groove, and the rope body is separated from the limiting sleeve.

[0015] In actual use, the rope body and the limiting sleeve need to be separated subsequently, and therefore the disengaging portion is arranged. When the rope body and the limiting sleeve need to be separated, the rope body is moved towards the direction close to the bottom of the limiting groove. At this time, the rope body is bent, and the rope core continues to move towards the direction close to the bottom of the limiting groove until the disengaging portion is embedded in the strip-shaped groove. Then, the rope body is moved away from the bottom of the limiting groove. The disengaging portion is resisted by the groove wall of the strip-shaped groove and moves away from the bottom of the limiting groove. When the disengaging portion abuts against the sliding block, the sliding block moves away from the axis of the limiting sleeve. At this time, the sliding block abuts against the rope body to make the rope body further deform. With the continuous movement of the rope body, the disengaging portion is disengaged from the strip-shaped groove, and the rope body is disengaged from the limiting sleeve.

[0016] Further, the groove wall of the limiting groove is provided with a mounting groove located on the side close to the clamping groove. The extending direction of the mounting groove is the axis direction of the connecting sleeve. The disengaging portion comprises a mounting block, a disengaging spring and a disengaging block. The mounting block is connected with the limiting spring, and the mounting block slides on the groove wall of the mounting groove. The sliding direction of the mounting block is the extending direction of the mounting groove. The end of the mounting block close to the axis of the limiting sleeve is provided with a disengaging groove. The disengaging spring is located at the bottom of the disengaging groove. The disengaging block is located at the end of the disengaging spring away from the bottom of the disengaging groove. The end of the disengaging block away from the bottom of the disengaging groove protrudes from the groove wall of the limiting groove. The elastic force of the disengaging spring limits the movement of the disengaging block towards the bottom of the disengaging groove. The end of the disengaging block away from the bottom of the disengaging groove is provided with an abutting surface one and an abutting surface two. The abutting surface one and the abutting surface two are used to abut against the groove wall of the strip-shaped groove to make the disengaging block move towards the bottom of the disengaging groove.

[0017] Through the above technical scheme, the disengaging portion comprises a mounting block, a disengaging spring and a disengaging block. When the rope body needs to be disengaged from the limiting sleeve, the rope body is first moved towards the bottom of the limiting groove to make the disengaging spring deform and thus make the disengaging block embedded in the strip-shaped groove. Then, the rope body is moved away from the bottom of the limiting groove to make the groove wall of the strip-shaped groove abut against the disengaging block and make the disengaging block drive the mounting block to move towards the sliding block. The disengaging block abuts against the sliding block to make the sliding block move away from the axis of the limiting sleeve. With the continuous pulling of the rope body, the abutting surface two makes the disengaging block move towards the bottom of the disengaging groove, and the rope core is disengaged from the limiting groove.

[0018] Further, the mounting block is provided with an inclined surface two located at the end close to the sliding block. The sliding block is provided with a moving groove. The bottom of the moving groove is provided with an inclined surface three extending towards the mounting block away from the bottom of the strip-shaped groove. The inclined surface three is used to abut against the inclined surface two.

[0019] By the technical scheme, the inclined surface three is arranged to move the sliding block away from the axis of the limiting sleeve when the inclined surface three abuts against the inclined surface two, and if only the inclined surface three is arranged, the sliding block moves when the wall of the strip-shaped groove abuts against the inclined surface three, which reduces the tightness of the connection between the limiting sleeve and the rope body. Therefore, the moving groove is arranged to reduce the situation that the sliding block moves when the wall of the strip-shaped groove abuts against the inclined surface three, and the structural strength is improved.

[0020] A processing technology of a high-strength net rope for a deep-sea aquaculture net cage, which is used for forming any one of the deep-sea aquaculture net cages described above, comprises the following steps:

[0021] Step one: winding and weaving the rope body with the rope core to form a rope body;

[0022] Step two: performing heat treatment on the rope body by hot water at 30-70 degrees, and then pre-tensioning the rope body by 5%-30%;

[0023] Step three: coating the rope body by wear-resistant paint.

[0024] By the technical scheme, the strength and hardness of the material can be improved, the heat resistance and corrosion resistance can be improved, the structural elongation of the rope body can be reduced and eliminated, the service life of the rope body can be improved, the wear resistance and corrosion resistance of the surface of the rope body can be improved by coating the rope body by wear-resistant paint.

[0028] (3) The moving groove and the inclined surface three are arranged, the inclined surface three is used to move the sliding block away from the axis of the limiting sleeve when the inclined surface three abuts against the inclined surface two, if only the inclined surface three is arranged, the sliding block moves when the wall of the strip-shaped groove abuts against the inclined surface three, which reduces the tightness of the connection between the limiting sleeve and the rope body. Therefore, the moving groove is arranged to reduce the situation that the sliding block moves when the wall of the strip-shaped groove abuts against the inclined surface three, and the structural strength is improved.

In actual use, the rope body 3 is a high molecular weight polyethylene cable, and the rope core 2 is a metal wire. The twisting method of the rope body 3 can be left-hand twist, right-hand twist, left-hand alternating twist, right-hand alternating twist, etc. In this embodiment, the rope body 3 has eight strands, and each set of limiting parts includes eight strip grooves 4. Alternatively, the rope body 3 can also have twelve strands.

[0038] The rope body 1 is provided with a limiting sleeve 5 at one end. The limiting sleeve 5 is in a columnar shape. The limiting sleeve 5 is provided with a connecting part one 6 and a connecting part two 7. The connecting part one 6 and the connecting part two 7 are respectively located at two ends of the limiting sleeve 5. The connecting part one 6 and the connecting part two 7 are consistent in structure. The connecting part one 6 is provided with a limiting slot 8 and a clamping slot 9. The slot opening direction of the limiting slot 8 is consistent with the slot opening direction of the clamping slot 9. The limiting slot 8 is used for embedding the rope core 2. The clamping slot 9 is used for embedding the rope body 3. In the embodiment, the limiting slot 8 is located at the axis of the limiting sleeve 5. The clamping slot 9 is distributed in a circumferential direction along the axis of the limiting sleeve 5 at one end of the connecting part one 6 provided with the limiting slot 8. The clamping slot 9 is provided with eight clamping slots. In actual use, the connecting part one 6 and the connecting part two 7 are used for temporarily connecting the rope body 1 at two ends.

[0039] The limiting sleeve 5 is provided with a sliding hole 10. The sliding hole 10 is communicated with the limiting slot 8 and the clamping slot 9. The sliding hole 10 is provided with a sliding block 11 which slides on the hole wall of the sliding hole 10. The sliding direction of the sliding block 11 is the axis direction of the sliding hole 10. The sliding block 11 is provided with an inclined surface one 12. The inclined surface one 12 is located at one end of the sliding block 11 which is away from the slot bottom of the limiting slot 8. The inclined surface one 12 extends in a direction away from the axis of the limiting sleeve 5 towards the direction close to the slot bottom of the limiting slot 8. The inclined surface one 12 is used for abutting against the rope core 2. One end of the sliding block 11 close to the slot bottom of the limiting slot 8 is provided with a moving slot 13. The moving slot 13 is provided with an inclined surface three 14 at the slot bottom. The inclined surface three 14 extends in a direction away from the slot bottom of the strip-shaped slot 4 towards the direction close to the mounting block 20.

The sliding block 11 is connected with a reset plate 17. The reset plate 17 is embedded in the reset slot 15. One end of the reset spring 16 is connected with the slot wall of the reset slot 15. The other end of the reset spring 16 is connected with the reset plate 17. The elastic force of the reset spring 16 limits the reset plate 17 to move in a direction close to the axis of the limiting sleeve 5.

[0041] When the rope core 2 is embedded in the limiting slot 8 and the rope body 3 is embedded in the clamping slot 9, the rope core 2 moves in a direction close to the slot bottom of the limiting slot 8 and makes the inclined surface one 12 of the sliding block 11 abut against the rope core 2. The movement of the rope core 2 makes the sliding block 11 move in a direction away from the axis of the limiting sleeve 5. The sliding block 11 moves and pushes the rope body 3 to abut against the slot wall of the clamping slot 9. In actual use, since the length of the rope body 3 after being straightened will be greater than the length of the rope core 2, the rope body 3 can also be embedded in the clamping slot 9 first, and then the rope core 2 is embedded in the limiting slot 8.

[0042] The slot wall of the limiting slot 8 is provided with a mounting slot 18. The mounting slot 18 is located at one side of the slot wall of the limiting slot 8 close to the clamping slot 9 and is located at one side of the clamping hole close to the slot bottom of the limiting slot 8.

The contact surface one 23 is located at one end of the disengaging block 22 away from the bottom of the limiting groove 8, and extends towards the axis of the limiting sleeve 5 in a direction away from the bottom of the limiting groove 8. The contact surface two 24 is located at one end of the disengaging block 22 close to the bottom of the limiting groove 8, and extends towards the axis of the limiting sleeve 5 in a direction close to the bottom of the limiting groove 8. The contact surface one 23 and the contact surface two 24 are used to contact the slot wall of the strip-shaped groove 4 to move the disengaging block 22 towards the bottom of the disengaging groove. In actual use, the contact surface one 23 and the contact surface two 24 can also be provided as arc surfaces.

[0045] The installation block 20 is provided with an inclined surface two 25, which is located at one end of the installation block 20 close to the sliding block 11, and is parallel to the inclined surface three 14.

In actual use, when the core 2 contacts the bottom of the limiting groove 8, the disengaging block 22 contacts the bottom of the strip-shaped groove 4. When the rope body 1 moves away from the bottom of the limiting groove 8, the slot wall of the strip-shaped groove 4 contacts the disengaging block 22 to move the disengaging block 22 away from the bottom of the limiting groove 8. The inclined surface two 25 of the installation block 20 contacts the inclined surface three 14 of the sliding block 11 to move the sliding block 11 away from the axis of the limiting sleeve 5. As the rope body 1 continues to move away from the bottom of the limiting groove 8, the disengaging block 22 moves towards the bottom of the installation groove 18 and disengages from the strip-shaped groove 4, and the rope body 1 disengages from the limiting sleeve 5.

[0047] A processing technology of high-strength net rope for deep-sea aquaculture net cage, which is used for forming the high-strength net rope for deep-sea aquaculture net cage, and comprises the following steps:

[0048] Step one: winding and weaving the rope body 3 with the rope core 2 to form the rope body 1;

[0049] Step two: heat treating the rope body 1 with 30-70 degree hot water, and then pre-tensioning 5%-30% tension;

[0051] The working principle of the embodiment is as follows:

[0052] In actual use, after the rope body 1 is cut off, the rope body 3 near the cutting position is straightened and embedded in the clamping groove 9, then the limiting sleeve 5 is moved so that the rope core 2 is embedded in the limiting groove 8, and when the rope core 2 is embedded in the limiting groove 8, the inclined surface one 12 of the sliding block 11 is abutted and the sliding block 11 is moved to abut against the rope body 3.

[0053] When it is needed to separate the rope body 3 from the limiting sleeve 5, the rope body 1 is moved away from the bottom of the limiting groove 8, the groove wall of the strip-shaped groove 4 abuts against the disengaging block 22 so that the disengaging block 22 is moved away from the bottom of the limiting groove 8. The inclined surface two 25 of the mounting block 20 abuts against the inclined surface three 14 of the sliding block 11, so that the sliding block 11 is moved away from the axis of the limiting sleeve 5. As the rope body 1 continues to move away from the bottom of the limiting groove 8, the disengaging block 22 moves toward the bottom of the mounting groove 18 and disengages from the strip-shaped groove 4, and the rope body 1 disengages from the limiting sleeve 5. The rope body 3 can also be taken out first, and then the rope core 2 is moved toward the bottom of the limiting groove 8, and when the disengaging block 22 is embedded in the strip-shaped groove 4, the rope core 2 is moved away from the bottom of the limiting groove 8 to separate the rope body 1 from the limiting sleeve 5.
