Description

Technical Field

[0001] The present invention relates to the technical field of deepwater deployment equipment, and in particular to a cable releasing device for releasing equipment in deep water. Background Art

[0002] In marine development technology, in order to complete deep-sea underwater observation and data collection, anchored weights are usually used to drive underwater equipment to move toward the seabed. The underwater equipment is connected to the anchor device through an anchor chain. Specifically, a release device is installed on the underwater equipment, and the release device is connected to the anchor device through an anchor chain. During operation, the anchor device moves underwater, driving the underwater equipment and the release device to move synchronously. When the underwater equipment moves downward to a specific depth driven by the anchor device and completes the corresponding observation and data collection operations, the underwater equipment needs to be recovered.

[0003] When recovering underwater equipment, it is necessary to separate the release device and the anchor device. The existing release device structure is mainly a release structure with a release hook. When releasing, the release hook is opened and separated from the anchor device. At this time, the anchor device, the underwater equipment and the release device are completely separated. The underwater equipment and the release device will float upward to the water surface under the action of buoyancy. At this time, the underwater equipment can be salvaged and recovered. After the release hook and the anchor device are separated, the underwater equipment will float around under the action of the waves and may float to any position with uncertain position. At this time, it is difficult to identify the underwater equipment by the color of the buoyancy material on the underwater equipment. Salvaging the underwater equipment is like looking for a needle in a haystack. It is very difficult and not easy to salvage and recover.

[0004] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application. Therefore, it may contain information that does not constitute the prior art known to ordinary technicians in this field. Summary of the Invention

[0005] Aiming at the problem that the release device structure in the prior art makes it difficult to recover underwater equipment, the present invention proposes a novel cable release device, which can realize the rapid salvage and recovery of underwater equipment and reduce the recovery difficulty.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0007] The present invention provides a cable release device, comprising:

[0008] a base body, wherein an installation space is formed inside the base body;

[0009] A rolling component is located in the installation space and is rotatably arranged on the base. A cable is wound around the rolling component, and the cable has a free end connected to the anchor device.

[0010] An elastic limiting structure is arranged on the base body and is used to limit the rotation of the rolling component;

[0011] A limiting component is arranged obliquely on the base and can slide relative to the base, and is used to be pressed on the elastic limiting structure to limit the elastic limiting structure;

[0012] A power suction device is arranged on the base;

[0013] A locking component, used to lock the limiting component, which can be separated from the limiting component under the action of the power suction device;

[0014] a first elastic element, located in the installation space and arranged between the locking component and the base, capable of applying an elastic force to the locking component to cause the locking component to extend into the limiting component to limit its position when the power suction device is separated from the locking component;

[0015] When the power device is powered on, the power suction device sucks the locking component, the locking component is separated from the limiting component, and the limiting component slides along the base to release the limit on the elastic limiting structure. When the limit is released, the elastic limiting structure pops out relative to the rolling component to eliminate the limit on the rolling component. When the elastic limiting structure eliminates the limit on the rolling component, the rolling component rotates relative to the base to lay out the cable wrapped around it.

[0016] When the power suction device is powered off, the power suction device is separated from the locking component, and the first elastic element applies a force to the locking component to make it extend into the limiting component to limit it. The limiting component is pressed on the elastic limiting structure to limit it, and the elastic limiting structure is inserted into the rolling component to limit the rotation of the rolling component.

[0017] In some embodiments of the present application, a positioning protrusion is formed on the outer side wall of the base, an inclined sliding track is formed on the positioning protrusion, and the limiting component is slidably disposed in the sliding track.

[0018] In some embodiments of the present application, the positioning protrusion is a positioning block fixedly provided on the outer wall of the base body, and there are two positioning blocks, which are arranged obliquely and symmetrically. A receiving space for accommodating a limiting component is formed between the inner walls of the two positioning blocks and the outer wall of the base body, and a sliding track is formed on the inner walls of the two positioning blocks. The limiting component is arranged in the receiving space and can slide along the sliding track.

[0019] In some embodiments of the present application, a sliding groove is provided on the outer wall of the base, the sliding groove is arranged at an angle, the limiting component is slidably set in the sliding groove, and a stop portion extending toward the inside of the sliding groove to prevent the limiting component from detaching from the sliding groove is provided on both sides of the sliding groove.

[0020] In some embodiments of the present application, a pressing portion is formed on one end of the limiting component, which is pressed on the elastic limiting structure through the pressing portion, and the other end is provided with a locking portion for inserting and cooperating with the locking component.

[0021] In some embodiments of the present application, the elastic limiting structure includes:

[0022] a position-limiting insert, which passes through the base and is inserted on the rolling component, and the position-limiting insert includes an abutting portion located outside the base;

[0023] The second elastic element is sleeved on the limiting insert, with one end abutting against the abutting portion and the other end abutting against the outer wall of the base.

[0024] In some embodiments of the present application, the locking component includes a locking body, a suction portion that engages with the power component is formed at one end of the locking body, a blocking component that is detachably connected to the locking body is provided at the other end of the locking body, and an insertion portion is formed on the blocking component for being inserted into the limiting component.

[0025] In some embodiments of the present application, the substrate includes:

[0026] The substrate includes:

[0027] Two oppositely disposed first and second base plates, the first and second base plates being connected by a connecting plate, the first and second base plates being respectively provided with a first through portion for passing the inserting portion and a second through portion for passing the locking body;

[0028] Wherein, when the cable is not laid, the locking body passes through the second passing portion, the insertion portion passes through the first passing portion and is inserted into the locking portion, and the suction portion is located on the outside of the second base plate and is arranged in contact with the outer side wall of the second base plate.

[0029] In some embodiments of the present application, the powered suction device includes a protective shell and an electric suction component built into the protective shell. A hollow cavity is formed in the protective shell, and the hollow cavity is filled with oil.

[0030] A cable release device, comprising:

[0031] a base body, wherein an installation space is formed inside the base body;

[0032] A rolling component is located in the installation space and is rotatably arranged on the base. A cable is wound around the rolling component, and the cable has a free end connected to the anchor device.

[0033] An elastic limiting structure is arranged on the base body and is used to limit the rotation of the rolling component;

[0034] A limiting component is arranged obliquely on the base and can slide relative to the base, and is used to be pressed on the elastic limiting structure to limit the elastic limiting structure;

[0035] A power device is arranged on the base;

[0036] A locking component, used to lock the limiting component, which can be moved and separated from the limiting component under the action of a power device;

[0037] The power device can drive the locking component to move by action, and the locking component is separated from the limiting component by action. The limiting component slides obliquely along the base to release the limit on the elastic limiting structure. When the limit is released, the elastic limiting structure pops out relative to the rolling component to eliminate the limit on the rolling component. When the limit of the elastic limiting structure is released, the rolling component rotates relative to the base to lay out the cable wrapped around it.

[0038] The power device can drive the locking component to move through action, so that the locking component extends into the limiting component to limit it, the limiting component is pressed on the elastic limiting structure to limit it, and the elastic limiting structure is inserted into the rolling component to limit the rotation of the rolling component.

[0040] The cable release device structure of the present invention is configured to connect and fix the anchor device and the cable when it is set. In this way, even if the cable release device is activated, the cable can be automatically opened to facilitate the ascent and surfacing of the underwater equipment. Moreover, after the underwater equipment floats up, the underwater equipment and the anchor device are also connected and fixed together by the cable. In this way, even if the underwater equipment floats to the water surface due to the buoyancy, since the anchor device is fixed at the bottom of the water and does not move, the underwater equipment will not float around on the water surface, but will stay at a fixed position because it is connected to the anchor device fixed at the bottom of the water and does not move. In this way, the position of the underwater equipment can be conveniently located and found, and the recovery operation of the underwater equipment can be conveniently and quickly carried out. When the underwater equipment is found, the cable can be cut.

[0054] The present invention provides an embodiment of a cable 300 release device, comprising:

[0055] The base 100 has an installation space 140 formed inside the base 100;

[0056] In some embodiments of the present application, the substrate 100 includes:

[0057] The first base plate 110 , the second base plate 120 and the connecting plate 130 for connecting the first base plate 100 and the second base plate 120 are connected to each other to form a U-shaped base plate 100 structure.

[0058] The first base plate 110 and the second base plate 120 are arranged opposite to each other, and the installation space 140 is formed between the first base plate 110 , the second base plate 120 and the connecting plate 130 .

[0059] A threaded mounting hole is provided on the connecting plate 130 , and a bolt is provided in the threaded mounting hole for connecting and fixing the base 100 and the underwater equipment 900 for underwater operation together.

[0060] The rolling component 200 is located in the installation space 140 and is rotatably disposed on the base 100. A cable 300 is wound around the rolling component 200. The cable 300 has a free end connected to an anchor device.

[0061] In some embodiments of the present application, the rolling component 200 is a drum. The cable 300 is wound around the surface of the drum, and the end of the cable 300 not wound around the drum surface, i.e., the free end, is used to connect to the anchor device.

[0062] During assembly, the roller is installed on the base 100 through the mounting shaft 800. The two ends of the roller are rotatably connected to the mounting shaft 800 through bearings. One end of the mounting shaft 800 has an external thread. The mounting shaft 800 passes through the first base plate 110 and the second base plate 120 in sequence and is locked and fixed to the base 100 by screwing the nut.

[0063] The elastic limiting structure 400 is arranged on the base 100 and is used to limit the rotation of the rolling component 200;

[0064] In some embodiments of the present application, the elastic limiting structure 400 includes:

[0065] A position-limiting insert 410 , which passes through the base 100 and is inserted into the rolling component 200 . The position-limiting insert 410 includes a supporting portion 411 located outside the base 100 .

[0066] The second elastic element 420 is sleeved on the limiting insert 410 , with one end abutting against the abutting portion 411 and the other end abutting against the outer wall of the base 100 .

[0067] The limiting insert 410 is a limiting insert pin, and the abutting portion 411 is an annular abutting protrusion formed on one end of the limiting insert 410 .

[0068] The second elastic element 420 is a second spring, which is sleeved on the limiting insertion pin, with one end abutting against the annular abutting protrusion and the other end abutting against the base 100 .

[0069] In some embodiments, an embedding groove is provided on the outer wall of the base 100 , and an avoidance hole is opened at the embedding groove. Specifically, an avoidance hole for avoidance is opened on the first base plate 110 , and the second elastic element 420 is partially located in the embedding groove.

[0070] In some embodiments of the present application, a spoke plate is provided on one side of the drum, a limiting hole 210 is provided on the spoke plate, and the avoidance hole and the limiting hole 210 are coaxially arranged.

[0071] During assembly, the limiting insertion pin passes through the second elastic element 420 and the avoidance hole in sequence and is inserted into the limiting hole 210 to clamp the roller and prevent the roller from rotating.

[0072] When the restriction imposed by the elastic limiting structure 400 is eliminated, the limiting plug-in 410 will be ejected outward under the reverse elastic force of the second elastic element 420, so as to separate it from the roller. At this time, the restriction on the roller is eliminated and the roller can rotate freely.

[0073] The limiting component 500 is arranged obliquely on the base 100 and can slide relative to the base 100, and is used to be pressed on the elastic limiting structure 400 to limit the elastic limiting structure 400;

[0074] In some embodiments of the present application, a pressing portion 510 is formed on one end of the limiting component 500, which is pressed onto the elastic limiting structure 400 through the pressing portion 510, and the pressing portion 510 is pressed on the outer side surface of the limiting plug-in pin to limit it; the other end is provided with a locking portion 520 for plugging and cooperating with the locking component 720.

[0075] In some embodiments, the locking portion 520 is a locking hole.

[0076] In order to realize the pressing and positioning of the elastic limiting structure 400 by the limiting component 500 , the limiting component 500 may be configured to be thinner at one end so as to form a pressing portion 510 by avoiding air gaps.

[0077] In some embodiments of the present application, a positioning protrusion is formed on the outer wall of the base 100 , an inclined sliding track 160 is formed on the positioning protrusion, and the limiting component 500 is slidably disposed in the sliding track 160 .

[0078] In some embodiments of the present application, the positioning protrusion is a positioning block 150 fixedly provided on the outer wall of the base 100. There are two positioning blocks 150, which are arranged obliquely and symmetrically. A receiving space for accommodating the limiting component 500 is formed between the inner walls of the two positioning blocks 150 and the outer wall of the base 100. A sliding rail 160 is formed on the inner walls of the two positioning blocks 150. The limiting component 500 is arranged in the receiving space and can slide along the sliding rail 160.

[0079] The limiting component 500 is slidably set on the base 100 and arranged at an angle, which ensures that after the limitation of the limiting component 500 is eliminated, it can slide relative to the base 100 and automatically fall due to its own gravity to release the limitation on the elastic limiting structure 400.

[0080] In other embodiments of the present application, the positioning protrusion may also be formed directly on the base 100 , with a slide formed inside the positioning protrusion so that it can slide relative to the base 100 and fall off automatically.

[0081] In other embodiments of the present application, a sliding groove is provided on the outer wall of the base 100, and the sliding groove is arranged at an angle. The limiting component 500 is slidably set in the sliding groove, and a stop portion extending toward the inside of the sliding groove to prevent the limiting component 500 from detaching from the sliding groove is provided on both sides of the sliding groove.

[0082] A concave sliding groove can also be provided on the outer side wall of the base 100, such as a sliding groove provided on the first base plate 110, extending from the middle position to one of the side positions of the first base plate 110, and the limiting component 500 is slidably set in the sliding groove, and the sliding groove is arranged obliquely from top to bottom. The pressing portion 510 at the end of the limiting component 500 is pressed on the elastic limiting structure 400, and the pressing portion 510 can be formed by bending upward relative to the limiting component 500 body.

[0083] When the limiting element is limited, it presses on the elastic limiting structure 400 through the pressing part 510 to limit the elastic limiting structure 400. When the limitation of the limiting element is eliminated, it tilts and slides relative to the base 100 under the action of its own gravity to release the limitation on the elastic limiting structure 400.

[0084] The power suction device 710 is arranged on the base 100;

[0085] In some embodiments of the present application, the power suction device 710 includes a protective shell 711 and an electric suction component 712 built into the protective shell 711, and the electric suction component 712 is an electromagnet.

[0086] The locking component 720 is used to lock the limiting component 500 and can be separated from the limiting component 500 under the action of the power suction device 710;

[0087] In some embodiments of the present application, the locking component 720 includes a locking body 721, at one end of which is formed a suction portion 722 for suctioning the power component, and at the other end of the locking body 721 is provided a blocking component 723 detachably connected to the locking body 721, and on the blocking component is formed an insertion portion 724 for being inserted into the limiting component 500.

[0088] The locking body 721 is a locking column, and the suction portion 722 is a raised disk formed at the end of the locking body 721 , which is made of iron and is used to be suctioned and cooperated with the power suction device 710 .

[0089] The blocking component 723 is a blocking disk, which is connected and fixed to the locking body 721 via bolts, so that the blocking component 723 can be detached from the locking body 721 .

[0090] A first through portion for passing through the insertion portion 724 and a second through portion for passing through the locking body 721 are respectively provided on the first base plate 110 and the second base plate 120;

[0091] The first through portion is a first through hole, and the second through portion is a second through hole.

[0092] The blocking component 723 is configured to be detachable relative to the locking body 721 , which can facilitate installation and removal of the locking component 720 .

[0093] During assembly, the blocking component 723 is removed, and then the locking body 721 is passed through the second passing portion. The suction portion 722 located at one end of the locking body 721 is arranged at the outer position of the installation space 140 and does not pass through the second passing portion. Then, the blocking component 723 is assembled, and the insertion portion 724 of the blocking component 723 is passed through the first passing portion to prevent the locking component 720 from detaching from the installation base 100.

[0094] The insertion portion 724 is an insertion positioning column arranged on the end face of the blocking component 723. Two insertion positioning columns can be set. During positioning, one of the two insertion positioning columns is used to be inserted into the locking hole on the limiting component 500 to achieve the limitation of the limiting component 500.

[0095] The first elastic element 730 is located in the installation space 140 and is arranged between the locking component 720 and the base 100. The first elastic element 730 is capable of applying an elastic force to the locking component 720 to extend it into the limiting component 500 to limit it when the power suction device 710 is separated from the locking component 720;

[0096] In some embodiments of the present application, the first elastic element 730 is a spring, which is sleeved on the locking body 721 , with one end resting on the blocking component 723 and the other end resting on the inner wall of the second base plate 120 .

[0097] When the dynamic suction device 710 is not sucked and fixed together with the suction part 722, since the first elastic element 730 is compressed between the second base plate 120 and the blocking part 723, the first elastic element 730 will apply an elastic force to the blocking part 723, so that it drives the insertion part 724 located above it to extend into the limiting part 500 to limit it.

[0098] When the power attraction device 710 is powered on, it is attracted together with the attraction portion 722. At this time, the insertion portion 724 in the locking component 720 is disengaged from the locking hole, and the position restriction of the limiting component 500 is eliminated.

[0099] When the power suction device 710 is powered off, it is separated from the suction portion 722 , and the locking component 720 is inserted into the locking hole of the limiting component 500 under the action of the second elastic element 420 to limit the limiting component 500 .

[0100] When the power device is powered on, the power suction device 710 suctions the locking component 720, the locking component 720 is separated from the limiting component 500, and the limiting component 500 slides along the base 100 to release the limit on the elastic limiting structure 400. When the limit is released, the elastic limiting structure 400 pops out relative to the rolling component 200 to eliminate the limit on the rolling component 200. When the elastic limiting structure 400 eliminates the limit on the rolling component 200, the rolling component 200 rotates relative to the base 100 to lay out the cable 300 wrapped around it.

[0101] When the power suction device 710 is powered off, the power suction device 710 is separated from the locking component 720, and the first elastic element applies a force to the locking component 720 so that it extends into the limiting component 500 to limit it. The limiting component 500 is pressed on the elastic limiting structure 400 to limit it, and the elastic limiting structure 400 is inserted into the rolling component 200 to limit the rotation of the rolling component 200.

[0102] In this embodiment, the cable 300 release device is in the initial state, the power suction device 710 is not powered, and the locking component 720 is subjected to the elastic force of the first elastic element 730 to pass through the first passing portion on the first base plate 110 and insert into the locking hole of the limiting component 500. The limiting component 500 is pressed and fixed by the pressing portion 510. The limiting plug-in 410 of the elastic limiting structure 400 compresses the second elastic element 420 and passes through the first base plate 110 and is inserted into the limiting hole 210 of the drum web to prevent the drum from rotating.

[0103] When the cable 300 release device receives the recovery release command, the electric suction component 712 in the power suction device 710 is energized. At this time, the electric suction component 712 is suctioned and fitted with the suction portion 722 of the locking component 720. Under the suction force of the electric suction component 712, the end of the locking component 720 is separated from the locking hole of the limiting component 500, and the limit of the limiting component 500 is eliminated. The limiting component 500 is not fixed in the limit position and slides out obliquely downward along the base 100 under the action of gravity. The limiting component 500 The limit of the limit plug 410 disappears. At this time, the second elastic element 420 arranged between the limit plug 410 and the first base plate 110 pops the limit plug 410 outward, and the limit plug 410 disengages from the limit hole 210 of the drum web, and the drum rotates freely. At this time, the cable 300 wrapped around the drum is gradually opened, and the underwater equipment 900 connected to the cable 300 release device floats up due to the buoyancy. After the underwater equipment 900 floats up, the underwater equipment 900 can be recovered.

[0104] The cable 300 release device structure in this embodiment is configured such that the anchor device and the cable 300 are connected and fixed when being set. In this way, even when the cable 300 release device is actuated, the cable 300 can be automatically opened to facilitate the ascent and surfacing of the underwater equipment 900. Moreover, after the underwater equipment 900 is surfaced, the underwater equipment 900 and the anchor device are still connected and fixed together by the cable 300. In this way, even if the underwater equipment 900 is floated to the surface by the buoyancy, since the anchor device is fixed at the bottom of the water and does not move, the underwater equipment 900 will not float around on the water surface, but will stay at a fixed position because it is connected to the anchor device fixed at the bottom of the water and does not move. In this way, the position of the underwater equipment 900 can be conveniently located and found, and the recovery operation of the underwater equipment 900 can be conveniently and quickly performed. When the underwater equipment 900 is found, the cable 300 can be cut.

[0105] The cable 300 release device in this embodiment does not require a release hook to be installed at the bottom of the equipment cabin, does not require a motor drive, does not require additional debugging, is easy to install, has simple control logic, and avoids situations such as inability to unhook or jamming due to failure of the motor and internal shaft to cooperate.

[0106] The present invention is installed at the bottom outside the equipment cabin and is fixed to the buoyancy material protective cover by screws. The internal structural principle is that the electromagnet drives the locking component 720 to move horizontally. The function is reliable and does not require additional space in the equipment cabin, thereby increasing the overall design of the beacon's internal battery and circuit board.

[0107] In some embodiments of the present application, the power suction device 710 includes a protective shell 711 and an electric suction component 712 built into the protective shell 711. A hollow cavity is formed in the protective shell 711, and the hollow cavity is filled with oil.

[0108] The protective shell 711 is made of nylon material and is non-conductive. The internal hollow cavity is filled with oil to enhance the underwater pressure resistance of nylon. The electric suction component 712 is installed inside the protective shell 711. An assembly gap is left between the protective shell 711 and the base 100. The protective shell 711 is fixedly connected to the base 100 by bolts.

[0109] This embodiment also provides an embodiment of a cable release device, including:

[0110] The base 100 has an installation space 140 formed inside the base 100;

[0111] The rolling component 200 is located in the installation space 140 and is rotatably disposed on the base 100. A cable 300 is wound around the rolling component 200. The cable 300 has a free end connected to an anchor device.

[0112] The elastic limiting structure 400 is arranged on the base 100 and is used to limit the rotation of the rolling component 200;

[0113] The limiting component 500 is arranged obliquely on the base 100 and can slide relative to the base 100, and is used to be pressed on the elastic limiting structure 400 to limit the elastic limiting structure 400;

[0114] A power device is arranged on the base 100;

[0115] A locking component 720 is used to lock the limiting component 500 and can be separated from the limiting component 500 under the action of a power device;

[0116] The power device can drive the locking component 720 to move by movement, and the locking component 720 moves to separate from the limiting component 500, and the limiting component 500 slides along the base 100 to release the limit on the elastic limiting structure 400. When the limit is released, the elastic limiting structure 400 pops out relative to the rolling component 200 to eliminate the limit on the rolling component 200. When the limit of the elastic limiting structure 400 is released, the rolling component 200 rotates relative to the base 100 to lay out the cable 300 wrapped thereon.

[0117] The power device can drive the locking component 720 to move through action, so that the locking component 720 extends into the limiting component 500 to limit it, the limiting component 500 is pressed on the elastic limiting structure 400 to limit it, and the elastic limiting structure 400 is inserted into the rolling component 200 to limit the rotation of the rolling component 200.

[0118] The power device in this embodiment can be an electric push rod, which is connected to the locking component 720 to drive the locking component 720 to move and insert into the locking hole of the limiting component 500 to limit it. The limiting component 500 limits the elastic limiting structure 400, and the elastic limiting structure 400 limits the rolling component 200.

[0119] When deployment is required, the locking component 720 can be driven by a power device to move so that it can be disengaged from the locking hole of the limiting component 500, thereby releasing the limiting effect of the limiting component 500 on the elastic limiting structure 400, and further eliminating the limiting effect of the elastic limiting structure 400 on the roller, so that the roller can rotate and the cable 300 can be released.

[0120] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
