Description

Technical Field

[0001] This application relates to the field of marine exploration equipment technology, and in particular to a connection node for marine exploration with a rope locking function. Background Technology

[0002] In the field of marine exploration, to achieve continuous and three-dimensional monitoring of specific sea areas, multiple detection modules are often fixed to nylon ropes via connecting structures to form a linear detection array. The connecting structure, acting as a bridge between the detection modules and the ropes, directly affects the deployment efficiency, operational stability, and equipment safety of the detection array. However, current methods for connecting nodes to ropes in marine exploration involve manually slipping a hanging ring onto the rope or using simple components such as cotter pins and clamps to fix the hanging ring to the rope. This is inefficient and results in poor stability of the fixing between the hanging ring and the rope.

[0003] In the existing technology, an integrated elastic seat and a cantilevered pressing spring arm structure are used. The shear force is generated by the radial misalignment of the spring arm and the hole of the seat body to clamp the rope. In this method, it is not convenient to quickly fasten the clamping mechanism to the rope, which increases the time to connect the node body to the rope and reduces the deployment efficiency of the node body. Summary of the Invention

[0004] The purpose of this application is to provide a connection node with rope locking function for marine exploration, including:

[0005] The mounting shell has a node slot inside, which is used to install the marine exploration node body;

[0006] A clamping mechanism includes a clamping block fixedly connected to the top of a mounting shell. The clamping block and the top of the mounting shell form a clamping groove with a side opening. Multiple rotating grooves are opened through the top of the clamping block. A rotating shaft is rotatably connected to the inner wall of the rotating groove near the opening of the groove. A torsion spring is fixedly connected between the rotating shaft and the inner wall of the rotating groove. A locking block is fixedly connected to the rotating shaft. The end of the locking block away from the rotating shaft abuts against the bottom of the groove. A rope is clamped between the locking block and the inner wall of the groove.

[0007] According to one aspect of the embodiments of this application, the mounting shell includes an upper shell, one end of which is rotatably connected to a lower shell, and the other end of which is connected to the other end of the lower shell by a fixing member. When the upper shell and the lower shell are closed, they form a node groove inside each other, and the clamping block is fixedly connected to the top of the upper shell.

[0008] According to one aspect of the embodiments of this application, the upper sleeve has a plurality of threaded holes at the end away from the lower sleeve, the fastener includes a screw threaded into the threaded hole, and the lower sleeve has a threaded groove that engages with the screw.

[0009] According to one aspect of the embodiments of this application, a limiting groove is formed in the inner wall of the clamping block constituting the clamping groove, a limiting block is slidably connected inside the limiting groove, a limiting spring is fixedly connected between the limiting block and the inner wall of the limiting groove, and the end of the limiting block away from the limiting spring abuts against the side of the rope away from the clamping block.

[0010] According to one aspect of the embodiments of this application, the top of the upper sleeve forming the bottom of the clamping groove is provided with a rope groove, the rope groove being semi-circular and fitting against the bottom of the rope.

[0011] According to one aspect of the embodiments of this application, the card block and the limiting block are respectively formed with a first arc-shaped surface and a second arc-shaped surface on opposite sides, and the rope groove, the first arc-shaped surface and the second arc-shaped surface form a circular groove, and the circular groove is coaxially engaged with the rope.

[0012] According to one aspect of the embodiments of this application, compression pads are fixedly connected to the inner sides of the rope groove, the first arc-shaped surface, and the second arc-shaped surface, and the circular groove abuts against the outer side of the rope through the three compression pads.

[0013] According to one aspect of the embodiments of this application, the compression pad is made of seawater corrosion resistant water-absorbing and swelling rubber, and the compression pad is tightly attached to the outside of the rope after absorbing water and swelling.

[0014] In summary, the beneficial technical effects of this application are as follows:

[0015] 1. In this utility model, the clamping mechanism automatically resets and locks the clamping block by driving the clamping block with a torsion spring, and pushes the limiting block to abut against the side with a limiting spring. After the rope is inserted into the clamping groove, it can be locked immediately without the need for manual tightening. Compared with the traditional time-consuming and laborious connection method of manually hanging rings and tightening bolts, it shortens the connection time between the single node body and the rope, improves the deployment efficiency of the node body, and can quickly separate the device from the rope by moving the clamping block, making it convenient to retrieve the node body. The rope groove, clamping block and limiting block form a three-way limiting structure for the rope. By uniformly squeezing the rope through surface contact, it effectively avoids the axial sliding or radial displacement of the node caused by the impact of ocean currents and wave vibrations.

[0016] 2. In this utility model, the elastic compression pad can buffer the rigid collision between the rope and other components, reduce the vibration generated by the water flow impact from being transmitted to the internal detection node, and at the same time avoid wear caused by excessive local stress on the rope, thus extending the service life of the rope and the node. The compression pad is made of seawater corrosion resistant water-absorbing and expanding rubber. After entering the sea, it absorbs water and expands to form an interference fit, so that the locking force dynamically increases with the deployment time, solving the problem of loosening caused by the elastic decay of traditional rubber pads after long-term use.

[0025] The following is combined Figures 1 to 3 The connection node with rope locking function for marine exploration according to the embodiments of this application will be described in detail.

[0026] See appendix Figure 1 To be continued Figure 3 A connection node for marine exploration with rope locking function, comprising:

[0027] This connection node is designed specifically for marine exploration scenarios. By integrating a mounting shell and a clamping mechanism, it enables rapid locking and fixation of the node body and ropes for marine exploration, making it suitable for deployment of exploration equipment in various marine environments.

[0028] The mounting shell has a node slot 3 inside, which is used to install the marine exploration node body.

[0029] The mounting shell serves as a protective and load-bearing structure for the node body. The size and shape of its internal node slot 3 are adapted to the node body used for marine exploration, thus providing physical protection for the node body.

[0030] The mounting housing includes an upper housing 1, one end of which is rotatably connected to a lower housing 2, and the other end of the upper housing 1 is connected to the other end of the lower housing 2 by a fixing member. When the upper housing 1 and the lower housing 2 are closed, they form a node groove 3 inside.

[0031] The upper shell 1 and the lower shell 2 adopt a rotating connection and a locking structure with fasteners, which facilitates the quick installation and replacement of the node body and creates an installation space after closing, thus enhancing the protection of the node body.

[0032] The upper sleeve 1 has multiple threaded holes 5 at the end away from the lower sleeve 2. The fastener includes a screw 4 that is threaded into the threaded hole 5. The lower sleeve 2 has a threaded groove 6 that is threaded to engage with the screw 4.

[0033] The screw 4 and the threaded groove 6 are used as fasteners, which have high connection strength and are detachable, making it easy to maintain later.

[0034] The clamping mechanism includes a clamping block 7 fixedly connected to the top of the mounting housing, and the clamping block 7 is fixedly connected to the top of the upper housing 1.

[0035] The clamping mechanism is the core component for connecting the node body and the rope. It is fixed to the top of the upper shell 1 and can move synchronously with the entire mounting shell to ensure the relative position stability of the node body and the rope.

[0036] The clamping block 7 and the top of the mounting shell form a clamping groove 8 with a side opening. Multiple rotating grooves 10 are opened through the top of the clamping block 7. A rotating shaft 11 is rotatably connected to the inner wall of the rotating groove 10 near the opening of the clamping groove 8. A torsion spring 12 is fixedly connected between the rotating shaft 11 and the inner wall of the rotating groove 10. A locking block 13 is fixedly connected to the rotating shaft 11. The end of the locking block 13 away from the rotating shaft 11 abuts against the bottom of the clamping groove 8. A rope is clamped between the locking block 13 and the inner wall of the clamping groove 8.

[0037] The side opening design of the clamping groove 8 facilitates the horizontal insertion of the rope. Under the elastic force of the torsion spring 12, the locking block 13 always tends to rotate towards the bottom of the clamping groove 8. When the rope pushes the locking block 13 into the clamping groove 8, the locking block 13 returns to its original position under the elastic force of the torsion spring 12, which can automatically tighten the rope and achieve initial locking. The design of multiple rotating grooves 10 and locking blocks 13 can distribute the locking force and avoid excessive force on a single point, which may cause rope damage.

[0038] A limiting groove 15 is provided on the inner wall of the clamping block 7 that forms the clamping groove 8. A limiting block 16 is slidably connected inside the limiting groove 15. A limiting spring 18 is fixedly connected between the limiting block 16 and the inner wall of the limiting groove 15. The end of the limiting block 16 away from the limiting spring 18 abuts against the side of the rope away from the clamping block 13.

[0039] Under the elastic force of the limiting spring 18, the limiting block 16 presses against the rope from the side, forming a two-way locking structure with the locking block 13. This can effectively prevent the rope from sliding axially or shifting radially within the clamping groove 8, and is especially suitable for rope swaying caused by water flow impact in marine environments.

[0040] The top of the upper sleeve 1, which forms the bottom of the clamping groove 8, has a rope groove 9. The rope groove 9 is semi-circular and fits against the bottom of the rope.

[0041] The semi-circular rope groove 9 matches the bottom contour of the rope, which can increase the contact area between the rope and the mounting shell, disperse the tension on the rope, and provide bottom support for the rope to prevent it from falling off the bottom of the groove 8 due to gravity or external force.

[0042] The locking block 13 and the limiting block 16 are respectively formed with a first arc-shaped surface 14 and a second arc-shaped surface 17 on opposite sides. The rope groove 9, the first arc-shaped surface 14 and the second arc-shaped surface 17 form a circular groove, which is coaxially fitted with the rope.

[0043] The circular groove replaces point contact with surface contact, which can improve locking stability and avoid excessive local pressure that could cause rope wear, thus extending the rope's service life.

[0044] The inner sides of the rope groove 9, the first arc surface 14, and the second arc surface 17 are all fixedly connected with compression pads 19, and the circular groove abuts against the outer side of the rope through the three compression pads 19.

[0045] The compression pad 19 can fill the tiny gap between the circular groove and the rope, increase the friction of the contact surface, and further improve the locking effect. At the same time, the elastic properties of the compression pad 19 can buffer the rigid collision between the rope and the clamping block 7 and the upper shell 1, and play a shock absorption and protection role.

[0046] The compression pad 19 is made of seawater corrosion resistant water-absorbing and swelling rubber. After the compression pad 19 absorbs water and expands, it fits tightly against the outside of the rope.

[0047] Seawater-resistant, water-absorbing, and swelling rubber is selected as the material for the extrusion pad 19, which is suitable for marine high-salt and high-humidity environments. On the one hand, its corrosion resistance ensures that it will not be eroded or fail by seawater during long-term use. On the other hand, its volume expansion after absorbing water allows the extrusion pad 19 to form an interference fit with the rope and the inner wall of the circular groove, thereby enhancing the mechanical locking force.

[0048] When using this utility model, unscrew the screw 4 at the connecting end of the upper shell 1 and the lower shell 2, so that the upper shell 1 can be flipped open around the rotating connecting end to expose the internal space of the node slot 3. Place the marine exploration node body into the node slot 3 of the lower shell 2, ensuring that the functional parts such as the wiring port and detection end of the node body are oriented in accordance with the deployment requirements. Flip the upper shell 1 and the lower shell 2 to close them. Pass the screw 4 through the threaded hole 5 of the upper shell 1, align it with the threaded slot 6 of the lower shell 2, and tighten it.

[0049] The nylon rope used for marine exploration deployment is aligned with the side opening of the clamping groove 8 of the clamping mechanism. The rope is pushed laterally along the opening of the clamping groove 8. The rope pushes the clamping block 13, forcing the clamping block 13 to rotate upward around the rotating axis 11 and compress the torsion spring 12 until the rope is fully inserted into the clamping groove 8. The bottom of the rope is in contact with the semi-circular surface of the rope groove 9. After the rope is in place, the torsion spring 12 releases its elastic force, causing the clamping block 13 to return to its original position downward. The first arc-shaped surface 14 presses tightly against the top of the rope. At the same time, the limiting block 16 pops out from the side under the elastic force of the limiting spring 18, and the second arc-shaped surface 17 presses against the side of the rope. The compression pads 19 on the inner sides of the rope groove 9, the first arc-shaped surface 14, and the second arc-shaped surface 17 initially fill the gap, increasing the friction of the contact surface and completing the mechanical locking.

[0050] The ropes connected to the node body are deployed into the sea at a preset depth and path. After the seawater comes into contact with the compression pad 19, the seawater corrosion-resistant water-absorbing and expanding rubber begins to absorb water and expand, gradually filling the tiny gaps between the circular groove and the rope, forming an interference fit, and enhancing the compression and locking force on the rope.

[0051] The device can be quickly detached from the rope by moving the locking block 13, making it easy to retrieve the marine exploration node.

[0052] The above description is merely a preferred embodiment of this application and is not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be included within the scope of protection of this application.
