Description

Technical Field

[0001] This application relates to the field of cable reeling and deployment devices, and in particular to an underwater cable reeling and deployment device. Background Technology

[0002] In existing technology, the cable reeling and deployment devices are prone to cable breakage problems after repeated reeling and deployment processes in an underwater environment. This causes the cable to get stuck on the drum, making it impossible to continue retrieving or releasing the cable. The cable breakage problem is more likely to occur when the cable to be reeled or deployed is too long. Summary of the Invention

[0003] The purpose of this application is to provide an underwater cable reeling and deployment device to solve the problem of cables easily breaking after repeated reeling and deployment. The specific technical solution is as follows:

[0004] A first aspect of this application provides an underwater cable reeling and unloading device, comprising: a drum; a motor assembly including a motor and a motor bracket, wherein the motor drives the drum, one end of the motor is fixed to the motor bracket and integrally disposed inside the drum; a cable laying assembly reciprocating along the length direction of the drum; a one-way friction wheel assembly including a one-way friction wheel, the rotation axis of the one-way friction wheel being arranged parallel to the rotation axis of the drum, the one-way friction wheel not rotating when the cable is reeled in, and rotating when the cable is released, the rotation direction being the same as the moving direction of the cable, and the linear velocity of the rotation being greater than the linear velocity of the drum; and a transmission assembly driven by the drum, driving the movement of the cable laying assembly and the rotation of the one-way friction wheel.

[0005] In some embodiments, the mounting gap between the motor and the motor bracket is filled with waterproof rubber, and the remaining mounting gaps of the underwater cable retraction device are filled with waterproof rings.

[0006] In some embodiments, the underwater cable deployment and retraction device further includes a tensioning wheel assembly disposed between the one-way friction wheel assembly and the cable deployment assembly, which continuously applies a clamping force to the cable.

[0007] In some embodiments, the tensioning wheel assembly includes a pulley and a spring, with a cable passing through one side of the pulley in the diametrical direction and the other side of the pulley in the diametrical direction being subjected to pressure from the spring.

[0008] In some embodiments, the underwater cable reeling and deployment device further includes a guide wheel assembly disposed between the unidirectional friction wheel assembly and the cable laying assembly, which plays a guiding role during the cable reversal process.

[0009] In some embodiments, the one-way friction wheel assembly further includes a ratchet and a pawl, the transmission assembly drives the ratchet to rotate, and the ratchet drives the one-way friction wheel to rotate through the pawl.

[0010] In some embodiments, the unidirectional friction wheel assembly further includes a follower friction wheel that rotates in the direction of cable movement. When the cable is released, the rotation direction of the follower friction wheel is opposite to that of the unidirectional friction wheel.

[0011] In some embodiments, the displacement generated by the cable laying assembly through the transmission component is the same for each rotation of the drum, and the magnitude of the displacement is the diameter of the cable plus the cable laying gap.

[0012] In some embodiments, the underwater cable reeling and deployment device further includes a reciprocating screw, on which the cable laying assembly moves and the transmission assembly drives the reciprocating screw to rotate.

[0013] In some embodiments, the transmission assembly includes a planetary gear, which includes a sun gear and planet gears. The sun gear is connected to the drum, and the planet gears drive the movement of the cable assembly and the rotation of the one-way friction wheel.

[0014] In some embodiments, the underwater cable reeling and unloading device further includes: a slip ring, comprising a rotor and a stator, wherein the rotor is fixedly connected to the drum and rotates with the drum, and the stator is disposed between the drum and the one-way friction wheel assembly.

[0015] Beneficial effects of the embodiments in this application:

[0016] The underwater cable reeling and unloading device provided in this application includes: a drum; a motor assembly including a motor and a motor bracket, wherein the motor drives the drum, one end of the motor is fixed to the motor bracket and is integrally disposed inside the drum; a cable laying assembly that reciprocates along the length direction of the drum; a one-way friction wheel assembly including a one-way friction wheel, the rotation axis of the one-way friction wheel being parallel to the rotation axis of the drum, the one-way friction wheel not rotating when the cable is reeled in, and rotating when the cable is released, the rotation direction being the same as the moving direction of the cable, and the linear velocity of the rotation being greater than the linear velocity of the drum; and a transmission assembly driven by the drum, which drives the movement of the cable laying assembly and the rotation of the one-way friction wheel.

[0017] When the cable is released, it is guided from the drum by the cable laying assembly and then released from the one-way friction wheel assembly. When the cable is retracted, it is guided from the one-way friction wheel assembly and wound onto the drum by the cable laying assembly. The cable laying assembly ensures that the cable is evenly wound on the drum, reducing the risk of uneven winding causing the cables to squeeze each other. The one-way friction wheel can only rotate in one direction. When retracting the cable, the one-way friction wheel is stationary, providing frictional resistance to the cable in the opposite direction of movement. When releasing the cable, the rotation direction of the one-way friction wheel is the same as the direction of cable movement, and the linear velocity of the one-way friction wheel is greater than the linear velocity of the drum. The cable on the one-way friction wheel experiences a tension force in the same direction as movement and a frictional force in the opposite direction of tension. Therefore, whether releasing or retracting the cable, it is always subjected to a frictional force in the opposite direction of movement, which helps to keep the cable in the underwater cable deployment and retrieval device taut. The cable in the underwater cable reel-and-deployment device can always be kept taut, and once taut, it can be evenly wound onto the drum. This ensures that the cable is always under uniform stress and is less likely to be squeezed against each other on the drum. It also reduces the impact of cable end vibration on the cable in the underwater cable reel-and-deployment device when the cable is released too long, which helps to reduce the risk of cable breakage. At the same time, placing the motor inside the drum reduces the risk of water entering the motor.

[0018] Of course, implementing any product or method of this application does not necessarily require achieving all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art based on this application are within the scope of protection of this application.

[0029] refer to Figure 1 and Figure 2 As shown, in a first aspect, this application provides an underwater cable reeling and unloading device 00, comprising: a drum 10; a motor assembly 20, including a motor 21 and a motor bracket 22, wherein the motor 21 drives the drum 10, one end of the motor 21 is fixed to the motor bracket 22 and is integrally disposed inside the drum 10; a cable laying assembly 30, which reciprocates along the length direction (X direction) of the drum 10; a one-way friction wheel assembly 40, including a one-way friction wheel 41, wherein the rotation axis of the one-way friction wheel 41 is parallel to the rotation axis of the drum 10, the one-way friction wheel 41 does not rotate when the cable 03 is reeled in, and rotates when the cable 03 is released, the rotation direction being the same as the movement direction of the cable 03, and the linear velocity of the rotation being greater than the linear velocity of the drum 10; and a transmission assembly 50, driven by the drum 10, driving the movement of the cable laying assembly 30 and the rotation of the one-way friction wheel 41.

[0030] In an exemplary embodiment, the installation gap of the underwater cable retraction device 00 is sealed, and the seal meets the IPX8 waterproof rating. The components in the underwater cable retraction device 00 that come into direct contact with water are selected to meet the IPX8 waterproof rating, which can reduce the risk of water entering the motor 21 and can be used for a long time in an immersion environment.

[0031] In an exemplary embodiment, one side of the drive assembly bracket of the drum 10 is a motor bracket 22, and the other side is a drive assembly bracket 04 for mounting the drive assembly 50; one side of the drive assembly 50 is a drive assembly bracket 04, and the other side is a one-way friction wheel assembly bracket 05 for mounting the one-way friction wheel assembly 40. The motor bracket 22 and the drive assembly bracket 04 are connected by a support rod. The cable laying assembly 30 reciprocates along the length direction (X direction) of the drum 10 between the motor bracket 22 and the drive assembly bracket 04. Bearings are provided between the drum 10 and the motor bracket 22, and between the drum 10 and the drive assembly bracket 04.

[0032] In an exemplary implementation, such as Figure 3 As shown, the cable laying assembly 30 has two cable laying pulleys 31 at its end. The cable 03 on the cable laying assembly 30 is located on different sides of the two cable laying pulleys 31. The cable 03 is straightened and then wound onto the drum 10.

[0033] In an exemplary embodiment, when the drum 10 starts to rotate, the transmission component 50 synchronously drives the movement of the cable laying component 30 and the rotation of the one-way friction wheel 41. By adjusting the transmission ratio between the transmission component 50 and the one-way friction wheel 41, the linear velocity of the one-way friction wheel 41 when rotating is greater than the linear velocity of the drum 10.

[0034] In an exemplary embodiment, a transmission gear is provided at the end of the drum 10 away from the motor assembly 20. The shaft of the transmission gear is connected to the shaft of the motor 21 inside the drum 10 via a coupling, and the transmission gear drives the transmission assembly 50.

[0035] When cable 03 is released, it is guided from the drum 10 by the cable routing assembly 30 and released from the one-way friction wheel assembly 40; when cable 03 is retracted, it is guided from the one-way friction wheel assembly 40 and wound back onto the drum 10 by the cable routing assembly 30. The cable routing assembly 30 ensures that cable 03 is wound evenly on the drum 10, reducing the risk of uneven winding causing the cables 03 to squeeze against each other. The one-way friction wheel 41 can only rotate in one direction. When retrieving the cable 03, the one-way friction wheel 41 is stationary, which will give the cable 03 being retrieved a frictional resistance opposite to the direction of movement. When releasing the cable 03, the rotation direction of the one-way friction wheel 41 is the same as the movement direction of the cable 03, and the rotational linear speed of the one-way friction wheel 41 is greater than the linear speed of the drum 10. The cable 03 on the one-way friction wheel 41 will be subjected to a tension force in the same direction as the movement direction, and also to a frictional force in the opposite direction of the tension force. Therefore, whether releasing or retrieving the cable 03, the cable 03 will always be subjected to a frictional force in the opposite direction of movement, which is beneficial to keep the cable 03 in the underwater cable retrieval device 00 in a taut state. The cable 03 in the underwater cable reel-and-delivery device 00 can always be kept taut, and after being taut, it can be evenly wound on the drum 10. This ensures that the cable 03 is always under uniform stress and is less likely to be squeezed against each other on the drum 10. It also reduces the impact of cable 03 end vibration on the cable 03 in the underwater cable reel-and-delivery device 00 when the cable 03 is released too long, which helps to reduce the risk of cable 03 breaking. At the same time, placing the motor 21 inside the drum 10 can reduce the risk of water entering the motor 21.

[0036] In some embodiments, reference Figure 2 As shown, the installation gap between the motor 21 and the motor bracket 22 is filled with waterproof rubber 01, and the remaining installation gaps of the underwater cable reeling device 00 are filled with waterproof rings 02.

[0037] In an exemplary embodiment, the waterproof ring 02 can withstand the deep water pressure and long-term immersion environment corresponding to IPX8.

[0038] In this embodiment, the waterproof rubber 01 can flow under water pressure and squeeze into gaps to achieve water stoppage. It also has the characteristics of aging resistance and high and low temperature resistance, which can meet the requirements of IPX8 long-term underwater immersion. Moreover, compared with glue waterproofing, it has higher strength and stronger tensile strength. Filling the installation gaps where water may seep into the drum 10 and cause water to enter the motor 21 with waterproof rubber 01 can reduce the risk of water entering the motor 21. The remaining mechanical connections are filled with waterproof rings 02, which enables the underwater cable reeling device 00 to meet the IPX8 waterproof condition.

[0039] In some embodiments, reference Figure 1As shown, the underwater cable deployment and retrieval device 00 also includes a tensioning wheel assembly 60, which is disposed between the one-way friction wheel assembly 40 and the cable laying assembly 30, and continuously applies a clamping force to the cable 03.

[0040] In an exemplary embodiment, the tensioner assembly 60 is disposed on the transmission assembly bracket 04.

[0041] In this embodiment, the tensioning wheel assembly 60 continuously applies a clamping force to the cable 03, which helps to keep the cable 03 in the underwater cable reeling device 00 in a clamped state, thereby reducing the risk of the cable 03 breaking.

[0042] In some embodiments, reference Figure 4 As shown, the tensioning wheel assembly 60 includes a pulley 61 and a spring 62. The cable 03 passes through one side of the pulley 61 in the diameter direction, and the other side of the pulley 61 in the diameter direction is subjected to pressure from the spring 62.

[0043] In an exemplary implementation, reference Figure 1 As shown, pulley 61 is positioned below spring 62 in the release direction of cable 03.

[0044] In an exemplary implementation, reference Figure 4 As shown, pulley 61 is mounted on the slider of pulley mounting base 63. The pulley mounting base 63 is provided with a slide rail. The pulley 61 can slide on the slide rail with the slider. One end of spring 62 is mounted in spring mounting base 64, and the other end abuts against the slider of pulley mounting base 63. Spring 62 and pulley 61 are not in direct contact.

[0045] In this embodiment, when the underwater cable reel-in device 00 suddenly accelerates to release or suddenly decelerates to retract, or when the platform on which the underwater cable reel-in device 00 is installed (e.g., an underwater robot, a remotely controlled boat, etc.) is subjected to an impact, the tensioning wheel assembly 60 can passively compensate for the moment when the cable 03 becomes loose due to external force through the spring 62. This reduces the interference of external factors on the cable 03 in the underwater cable reel-in device 00, and helps to keep the cable 03 in the underwater cable reel-in device 00 in a compressed state, thereby reducing the risk of the cable 03 breaking.

[0046] In some embodiments, reference Figure 1 As shown, the underwater cable reeling and deployment device 00 also includes a guide wheel assembly 70, which is located between the one-way friction wheel assembly 40 and the cable laying assembly 30, and plays a guiding role during the reversal of the cable 03.

[0047] In an exemplary embodiment, the tensioning wheel assembly 60 is disposed between the one-way friction wheel assembly 40 and the cable laying assembly 30, and the guide wheel assembly 70 is disposed between the tensioning wheel assembly 60 and the cable laying assembly 30.

[0048] In an exemplary embodiment, the guide wheel assembly 70 is disposed between the transmission assembly bracket 04 and the one-way friction wheel assembly bracket 05, and is disposed on top of the underwater cable reeling device 00.

[0049] In this embodiment, since the cable 03 moves in different directions in the unidirectional friction wheel assembly 40 and the cable laying assembly 30, the guide wheel assembly 70 makes the cable's turning between the two smoother. This helps to keep the cable 03 in the underwater cable reel-in / deel-out device 00 always in a compressed state, thereby reducing the risk of the cable 03 breaking. Moreover, when the cable 03 changes direction, that is, when the drum 10 changes its rotation direction, since the cable 03 is always kept in a compressed state in the underwater cable reel-in / deel-out device 00, the guide wheel assembly 70 can convert the sliding friction between the cable 03 and the underwater cable reel-in / deel-out device 00 into the rolling friction of the guide wheel in the guide wheel assembly 70. This not only reduces the impact and vibration caused by the change in the acceleration direction of the cable 03 during the reversal, but also prevents the cable 03 from deviating from its original running path due to the reversal, and also reduces the risk of the cable 03 being worn by the underwater cable reel-in / deel-out device 00.

[0050] In some embodiments, reference Figure 5 As shown, the one-way friction wheel assembly 40 also includes a ratchet 42 and a pawl 43. The transmission assembly 50 drives the ratchet 42 to rotate, and the ratchet 42 drives the one-way friction wheel 41 to rotate through the pawl 43.

[0051] In an exemplary embodiment, the ratchet 42 and the one-way friction wheel 41 are coaxially arranged, and the pawl 43 is disposed between the ratchet 42 and the one-way friction wheel 41. The pawl 43 is connected to the torsion spring 44, and the one-way friction wheel 41 is driven only by the pawl 43.

[0052] In this embodiment, the ratchet 42 and pawl 43 are used to make the one-way friction wheel 41 rotate only in the release direction during release. This not only results in a simple structure and low failure rate, but also facilitates long-term underwater operation of the underwater cable reel-and-deployment device 00. When the cable 03 is subjected to external interference, the one-way friction wheel 41 is also restricted by the pawl 43 to prevent rotation in a direction different from the release direction, thus reducing the risk of interference to the cable 03 in the underwater cable reel-and-deployment device 00. The pawl 43 also plays a certain positioning role, which helps to keep the load of the cable 03 in a fixed position as needed.

[0053] In some embodiments, reference Figure 5 As shown, the one-way friction wheel assembly 40 also includes a follower friction wheel 45, which rotates in the direction of movement of the cable 03. When the cable 03 is released, the rotation direction of the follower friction wheel 45 is opposite to that of the one-way friction wheel 41.

[0054] In an exemplary implementation, reference Figure 1As shown, the follower friction wheel 45 is positioned below the unidirectional friction wheel 41 along the release direction of the cable 03, and the cable 03 is located on different sides of the follower friction wheel 45 and the unidirectional friction wheel 41.

[0055] In this embodiment, the follower friction wheel 45 and the one-way friction wheel 41 can provide multi-point support for the cable 03, distributing the tension of the cable 03 and reducing the average pressure on the cable 03 at various points on the follower friction wheel 45 and the one-way friction wheel 41, which is beneficial to extending the service life of the cable 03. The follower friction wheel 45 can also straighten the cable 03 and confine the cable in the one-way friction wheel assembly 40 between the follower friction wheel 45 and the one-way friction wheel 41, making it less likely for the cable 03 to detach from the one-way friction wheel assembly 40. This helps to keep the cable 03 in the underwater cable deployment and retrieval device 00 in a compressed state, thereby reducing the risk of the cable 03 breaking.

[0056] In some embodiments, the displacement generated by the cable laying assembly 30 through the transmission assembly 50 for each rotation of the drum 10 is the same, and the magnitude of the displacement is the diameter of the cable 03 plus the cable laying gap.

[0057] In this embodiment, the above-mentioned arrangement is conducive to the uniform winding of the cable 03 onto the drum 10, and there is a certain gap between the cables 03 wound on the drum 10, which can ensure that the cables 03 are always subjected to uniform force and are not easily squeezed against each other on the drum 10, thus reducing the risk of the cables 03 breaking.

[0058] In some embodiments, reference Figure 1 As shown, the underwater cable reeling and deployment device 00 also includes: a reciprocating screw 80, a cable laying assembly 30 that moves on the reciprocating screw 80, and a transmission assembly 50 that drives the reciprocating screw 80 to rotate.

[0059] In an exemplary embodiment, the reciprocating lead screw 80 is disposed along the X direction between the motor bracket 22 and the transmission component bracket 04. A connecting rod parallel to the reciprocating lead screw 80 is also disposed between the motor bracket 22 and the transmission component bracket 04. (See [link]) Figure 3 The cable assembly 30 has two connection holes, one for traveling on the reciprocating screw 80 and the other for sliding on the connecting rod.

[0060] In an exemplary embodiment, by adjusting the transmission ratio between the transmission assembly 50 and the reciprocating screw 80, the displacement generated by the cable laying assembly 30 driven by the transmission assembly 50 is the same for each rotation of the drum 10. The magnitude of the displacement is the diameter of the cable 03 plus the cable laying gap.

[0061] In this embodiment, the reciprocating screw 80 can precisely control the displacement of the cable laying assembly 30, and can maintain consistent stroke accuracy after multiple reciprocating movements without cumulative error. At the same time, the reciprocating screw 80 runs relatively smoothly and does not require an additional reversing mechanism. The reciprocating screw 80 can achieve automatic reciprocating movement through its own thread structure. The structure is simple and has a low failure rate, which is conducive to the underwater cable laying and winding device 00 adapting to long-term underwater operations.

[0062] In some embodiments, reference Figure 6 As shown, the transmission assembly 50 includes a planetary gear 51, which includes a sun gear 511 and planet gears 513. The sun gear 511 is connected to the drum 10, and the planet gears 513 drive the movement of the cable assembly 30 and the rotation of the one-way friction wheel 41.

[0063] In an exemplary embodiment, the motor 21 rotates, driving the drum 10 to rotate. The drum 10 is fixedly connected to the sun gear 511, which drives three planetary gears 513 to rotate. The three planetary gears 513 both rotate on their own axis and revolve around a central axis. The three planetary gears 513 are fitted into the three mounting posts of the planetary gear bracket 514, driving the planetary gear bracket 514 to rotate. The planetary gear bracket 514 drives the first transmission gear 515 to rotate, which in turn drives the second transmission gear 516 to rotate. The first transmission gear 515 drives the rotation of the one-way friction wheel 41, and the second transmission gear 516 drives the movement of the cable laying assembly 30. By adjusting the transmission ratio between the gears, the linear velocity of the one-way friction wheel 41 when it rotates is greater than the linear velocity of the drum 10. At the same time, the displacement generated by the drum 10 driving the cable laying assembly 30 through the transmission assembly 50 for each rotation is the same, and the magnitude of the displacement is the diameter of the cable 03 plus the cable laying gap.

[0064] In this embodiment, the sun gear 511 and planet gear 513 of the planetary gear 51 have multiple contact points and uniform force distribution, which can achieve a variety of different transmission ratios through a simple structure. Moreover, the failure rate is low, which is beneficial for the underwater cable reeling and laying device 00 to adapt to long-term underwater operations.

[0065] In some embodiments, reference Figure 7 As shown, the underwater cable reeling and unloading device 00 also includes: a slip ring 90, which includes a rotor 91 and a stator 92. The rotor 91 is fixedly connected to the drum 10 and rotates with the drum 10. The stator 92 is disposed between the drum 10 and the one-way friction wheel assembly 40.

[0066] In an exemplary embodiment, the stator 92 is fixed to the one-way friction wheel assembly bracket 05, and the connecting wire of the slip ring 90 passes through the one-way friction wheel assembly bracket 05, for reference. Figure 2 As shown, the installation gaps between the connecting line of the slip ring 90 and the bracket 05 of the one-way friction wheel assembly, as well as between the rotor 91 and the drum 10, are filled with waterproof rubber 01.

[0067] In this embodiment, the slip ring 90 can stably transmit power, control signals, and data signals to the motor 21 without frequent start-stop operations or unlimited rotation angles. Moreover, the slip ring 90 has a simple structure and low failure rate, which helps the underwater cable reeling and laying device 00 to adapt to long-term underwater operations.
