Description

Technical Field

[0001] The present invention belongs to the technical field of underwater equipment, and in particular relates to an improvement in the structure of a cable release control device. Background Art

[0002] In many cases, equipment needs to be transported to the seabed at a certain speed via a cable, or a certain component of the equipment needs to be controlled at a desired depth. Therefore, a reliable cable release control device is needed to complete this function.

[0003] In some existing cable release control devices, such as winches, the cable is wound on a cable drum. When laying the cable, the free end of the cable is connected to the anchor system. Under the action of the gravity of the anchor system, the cable drum is pulled to rotate to lower the cable. When lowering the cable under the condition of relatively large gravity of the anchor system, the force acting on the cable is relatively large, and the cable may be embedded in the inner layer of the cable drum and become stuck, resulting in the cable release control device being unable to operate normally. Summary of the Invention

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0058] The present invention provides an embodiment of a cable release control device, comprising:

[0059] The frame 110 includes a damping device 200, a brake device 400, a cable clamping device 300, a cable guide device 600, and a self-locking device 500. The underwater positioning and release device primarily cooperates with the anchor device for underwater deployment operations, ultimately maintaining the equipment it carries within a certain depth range and achieving precise depth-controlled release.

[0060] In some embodiments of the present application, the frame 110 includes:

[0061] There are two frame support end covers 111, which are arranged opposite to each other. The frame support end covers 111 are circular end covers;

[0062] and a connecting protection rod 112 connected between the two frame support end covers 111, wherein a plurality of connecting protection rods 112 are provided and arranged circumferentially along the frame support end covers 111;

[0063] The accommodation space is formed between the frame support end cover 111 and the connection protection rod 112 .

[0064] The frame supporting the end cover 111 and the plurality of connecting protection rods 112 form the support skeleton of the entire underwater depth-fixing release device.

[0065] In order to achieve the purpose of weight reduction, weight reduction holes are further opened on the frame support end cover 111. A plurality of weight reduction holes can be opened and evenly arranged on the frame support end cover 111.

[0066] The cable drum 120 is used for winding and arranging a cable, and the length of the cable drum extends from one frame support end cover 111 to another frame support end cover 111 .

[0067] The end portion thereof is protruded to form a drum shaft, and the drum shaft and the frame support end cover 111 are rotatably connected together to realize the rotatable connection between the cable drum 120 and the frame support end cover 111.

[0068] When lowering the cable, the cable drum 120 can be used to continuously release the cable relative to the frame support end cover 111.

[0069] In order to limit the winding length of the cable wound on the cable drum 120 , a rotation limiting disk is correspondingly provided at at least one end of the cable drum 120 , which is fixed integrally with the cable drum 120 .

[0070] The damping device 200 is arranged at one end of the frame 110 . Specifically, the damping device 200 is assembled on the frame support end cover 111 at one end.

[0071] The damping device 200 includes:

[0072] A damping mounting base 210 is mounted on the frame 110;

[0073] The cable damping device 220 is provided with at least one group, which includes:

[0074] There are two cable receiving members 221 , which are of different sizes and are both rotatably connected to the damping mounting base 210 .

[0075] In some embodiments of the present application, in order to achieve the rotational connection of the cable accommodating part 221, a first mounting shaft 230 is provided, and two of them are provided, both of which are rotationally connected to the damping mounting base 210, and the cable accommodating part 221 is assembled on each of the first mounting shafts 230.

[0076] A cable receiving portion 222 for winding and arranging a cable is formed on each of the cable receiving members 221. The cable receiving portion 222 can generate friction with the cable to reduce the force transmitted to the cable drum 120 and prevent the cable from being embedded.

[0077] The cable accommodating portion 222 is a cable accommodating groove opened along the circumference of the cable accommodating member 221. There are multiple cable accommodating grooves arranged along the axial direction of the cable accommodating member 221. The cable is wound and arranged in one or more of the cable accommodating grooves.

[0078] The cable accommodating member 221 is a cable accommodating wheel, and a plurality of cable accommodating grooves are defined on the upper portion thereof.

[0079] Winding the cable in the cable receiving groove can increase the damping force between the cable and the cable receiving groove;

[0080] The more turns the cable is wound around the cable container 221, the larger the contact area between the cable and the cable container 221 is, and the greater the damping friction generated. The number of turns of the cable container 221 is determined by the required damping strength. If strong damping is required, more turns are needed, and if weak damping is required, fewer turns are needed.

[0081] Of course, in order to ensure that the cable can move downward and be pulled after passing through the cable receiving member 221, the friction damping force between the cable and the cable receiving member 221 should not be too large, so as not to affect the normal cable delivery;

[0082] The diameters of the two cable accommodating wheels are set to be the same.

[0083] A first damping transmission device 240 is linked to the cable damping device 220 and can be driven to rotate when the cable receiving member 221 rotates;

[0084] In some embodiments of the present application, the first damping transmission device 240 includes:

[0085] A first damping assembly shaft 241 is rotatably mounted on the damping mounting base 210;

[0086] A first damping active member 242 is assembled on the first damping assembly shaft 241;

[0087] The first damping follower 243 is assembled on one of the first mounting shafts 230 and meshes with the first damping active member 242 .

[0088] In some embodiments of the present application, the first active damping member 242 is a first active damping gear;

[0089] The first damping follower 243 is a first driven damping gear, and the two are meshed with each other.

[0090] The cable on the cable drum 120 will be wound and opened under the gravity traction of the anchor device, and the opened cable passes through the cable accommodating part 221. Due to the friction between the cable accommodating part 221 and the cable, the cable accommodating part 221 will be driven to rotate relative to the damping mounting base 210. The rotation of the cable accommodating part 221 will drive the first mounting shaft 230 to rotate, and then drive the first damping follower 243 on the first mounting shaft 230 to rotate. Since the first damping follower 243 and the first damping active part 242 are engaged, the first damping rotating part is driven to rotate.

[0091] Since the first damping transmission device 240 and the cable accommodating member 221 are linked together, the damping effect between the cable accommodating member 221 and the cable is enhanced by the provision of the first damping device 200 .

[0092] The second damping transmission device 250 is linked with the cable damping device 220 to synchronize the two cable receiving members 221;

[0093] In some embodiments of the present application,

[0094] The second damping transmission device 250 is a damping sprocket 251 chain structure, which includes:

[0095] There are two damping sprockets 251, which are respectively assembled on the two first mounting shafts 230;

[0096] The damping chain 252 is wound around the two damping sprockets 251 .

[0097] The two sets of cable winding wheels of the damping system are equipped with synchronous chains, and the two damping sprockets 251 are connected together by the damping chain 252. Since the two damping sprockets 251 are respectively assembled on the first mounting shaft 230, they are coaxially arranged with the two cable accommodating parts 221. In this way, the two cable accommodating parts 221 connected to the damping sprocket 251 are driven by the damping chain 252 to achieve synchronous rotation. The purpose of ensuring the synchronous movement of the two cable accommodating parts 221 is to prevent one of the cable accommodating parts 221 from slipping or failing due to insufficient friction, to avoid the reduction of the damping effect due to slipping or failure, and to ensure the damping effect.

[0098] When the cable accommodating member 221 of this embodiment is not provided, when the anchor device is hung at the end of the cable, the weight of the anchor device will produce a downward pulling force on the cable, and the cable will transfer this pulling force to the cable at the cable drum 120. Due to the large force, the cable will be embedded in the inner layer of the multi-layer cables on the cable drum 120.

[0099] In this embodiment, the cables drawn out from the cable drum 120 are sequentially wound and arranged in the cable receiving grooves of the cable receiving member 221. When the cables are wound in the cable receiving grooves, friction is generated between the cables and the cable receiving grooves. The friction between the cables and the cable receiving grooves can achieve a force reduction effect on the force carried by the cables.

[0100] After the tension of the cable passes through the multi-stage friction of the two cable receiving parts 221, the force acting thereon will be reduced to a reasonable level.

[0101] As a result, the force on the cable is reduced when it is transmitted to the cable drum 120 , effectively avoiding the problem that the cable at the cable drum 120 is embedded in the inner layer due to the entire cable force being transmitted to the cable drum 120 .

[0102] The cable is wound around the cable accommodating member 221. The total wrap angle of the cable on the cable accommodating member 221 is defined as a. The downward pull at the cable connection to the anchor device, or the force on the traction end, is F1. The force on the cable drum leading to the cable storage winch is F2. f is the friction between the cable and the cable accommodating member 221. A small section of cable with a wrap angle da is analyzed for force. Using equilibrium conditions, the difference in tension at both ends is the friction force, F1 - F2 = f. When da is infinitely small, dN is the pressure on the cable, directed along the diameter of the pulley.

[0103] The greater the friction between the cable and the cable receiving member, the more obvious the force reduction effect.

[0104] a locking brake member connected to the first damping transmission device 240;

[0105] A locking mechanism 270 is arranged on the frame 110 and is used to brake or unlock the locking brake member;

[0106] When the locking brake is locked or unlocked, the first damping transmission device 240 can be locked or unlocked. When the first damping transmission device 240 is locked or unlocked by the damping locking member, the cable accommodating member 221 can be locked or unlocked.

[0107] In some embodiments of the present application,

[0108] The damping mounting base 210 includes relatively arranged damping mounting plates 211, and an accommodating space is formed between the two damping mounting plates 211. The two ends of the first damping assembly shaft 241 are respectively rotatably connected to the damping mounting plates 211, and the ends thereof extend from the damping mounting plates 211. The locking brake is assembled on the first damping assembly shaft 241.

[0109] When the locking brake needs to be locked, the locking action mechanism 270 can be controlled to operate to lock the locking brake. Since the locking brake is connected to the first damping assembly shaft 241 of the first damping transmission device 240, when the locking brake is locked, it correspondingly drives the first damping assembly shaft 241 to stop rotating, and then drives the first damping active member 242 and the first damping follower 243 assembled above it to engage and lock together, so as to drive the cable accommodating member 221 connected to the first damping follower 243 and another cable accommodating member 221 linked to it to be locked and fixed.

[0110] When the locking mechanism 270 is actuated, the first damping follower 243 and the first damping active member 242 can be locked together by the teeth engaging with each other, thereby effectively preventing the cable receiving member 221 and the cable from rotating.

[0111] In some embodiments of the present application, the locking mechanism 270 includes:

[0112] The locking body 271 is arranged around the locking brake, and one end of the locking body 271 is hinged to the damping mounting base 210. The locking body 271 is partially attached to the locking brake to provide a damping force to the locking brake;

[0113] a locking drive member 272 having a retractable extension;

[0114] The locking drive member 272 is a locking drive cylinder, and the extending portion is a locking extension arm, which can be used for telescopic action.

[0115] The locking linkage 273 is rotatably mounted on the damping mounting base 210, with one end hinged to the protruding portion and the other end hinged to the other end of the locking body 271. It can be driven by the locking drive 272 to drive the locking body 271 to move so that the locking body 271 rests on the locking brake to lock the first damping transmission device 240 or disengage from the first damping transmission device 240 to unlock the first damping transmission device 240.

[0116] The locking linkage 273 is a locking lever, which is rotatably connected to the damping mounting plate 211 via a connecting pin.

[0117] An insertion rod is formed at the end of the locking linkage member 273 , and an insertion hole is formed on the locking body 271 . The locking linkage member 273 is inserted into the insertion hole through the insertion rod to achieve a rotational connection with the locking body 271 .

[0118] In some embodiments of the present application,

[0119] An annular accommodating portion 261 is formed on the locking brake;

[0120] The locking body 271 is semi-annular and has an opening, and includes:

[0121] a main body portion, the main body portion being located in the accommodation portion and at least partially fitting with the annular accommodation portion 261;

[0122] And a first connecting portion 2711 and a second connecting portion 2712 are arranged on both sides of the opening and connected to both ends of the main body respectively. The first connecting portion 2711 and the second connecting portion 2712 are gradually farther away from the locking brake component than the main body.

[0123] When the locking driving member 272 and the locking linkage member 273 are not in action, the first connecting portion 2711 and the second connecting portion 2712 maintain a gradually varying distance from the locking brake member, so that the locking body 271 partially maintains contact with the locking brake member.

[0124] When braking is required, the first connecting portion 2711 and the second connecting portion 2712 at both ends can be driven to contact and press against the locking brake component to achieve a braking effect.

[0125] In some embodiments of the present application,

[0126] A cable stopper 280 is disposed on the damping mounting base 210 and is laterally arranged to connect the two damping mounting plates 211 . There are multiple cable stoppers 280 , which are arranged circumferentially along the damping mounting plates 211 .

[0127] The cable limiting member 280 is a cable limiting rod, and a plurality of cable limiting rods are provided to prevent the cables arranged in the damping mounting plate 211 from falling off.

[0128] The cable release control device in this embodiment can not only prevent the cable from getting stuck, but also can brake the cable. The braking method is to brake the cable through meshing gear parts, so the braking effect is good and the braking precision is high.

[0129] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to replace some of the technical features therein with equivalents.
