The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0035] like Figures 1 to 3 As shown, this embodiment provides a deep-sea towing and deployment system, which can complete the storage of the operating device 1000 and the deployment to the deep sea with the help of the mutual cooperation between the existing various mechanisms on the mother ship 100. There is no need to set up a separate deployment mechanism on the mother ship 100, so as to avoid occupying additional space on the mother ship 100; the mechanisms and resources on the mother ship 100 are reasonably utilized, the utilization rate of each mechanism is effectively improved, and resource waste is avoided.

[0036] It should be noted that the deep sea refers to a geographical term with high pressure, slow bottom water flow, and no light. In other embodiments, the operating device 1000 can be deployed below the water surface. Exemplarily, the operating device 1000 can be a submersible. The operating device 1000 is mainly used for underwater operations such as deep-sea salvage and rescue, underwater military reconnaissance, marine investigation and survey, cable and pipeline laying and maintenance, and underwater positioning archaeology.

[0037] In this embodiment, the deep-sea towing and deploying system includes a mother ship 100, which has a deckhouse 210, a first winch 220, a second winch 230, a crane 240 and an A-type hanger 250. The deckhouse 210 is used to store the operating device 1000, and the deckhouse 210 has a first opening 211; the first winch 220 is arranged on the deck 110 of the mother ship 100, and the first winch 220 is used to move the operating device 1000 from the first opening 211 of the deckhouse 210. towed out to the transfer position; an A-type hanger 250 is provided on the deck 110, and the A-type hanger 250 is used to transfer the operating device 1000 between the rear of the mother ship 100 and the top of the mother ship 100; a crane 240 is provided between the A-type hanger 250 and the transfer position, and the crane 240 is used to transfer the operating device 1000 between the A-type hanger 250 and the transfer position; the second winch 230 is wound with an umbilical cable 231, and one end of the umbilical cable 231 is connected to the operating device 1000.

[0038] The above arrangement does not require a separate deployment structure on the mother ship 100, thus avoiding additional occupation of the mother ship 100 space and effectively improving the transport capacity of the mother ship 100. The deployment of the operating device 1000 can be completed by only utilizing the mutual cooperation of the existing mechanisms on the mother ship 100, that is, the deckhouse 210, two winches, crane 240, A-type hanger 250 and other mechanisms in the mother ship 100 can cooperate with each other to complete the deployment function of the operating device 1000 in addition to their own functions. One thing has multiple uses, resources are used rationally, the utilization rate of each mechanism is effectively improved, and waste of resources is avoided.

[0039] When the crane 240 is used to transfer the working device 1000, the working device 1000 generally needs to be hoisted and suspended in the air. The suspended working device 1000 may cause the risk of falling. In order to reduce the suspended distance of the working device 1000 during the transfer process, in some embodiments, the transfer position is located between the deckhouse 210 and the crane 240. The working device 1000 is first dragged from the deckhouse 210 to the transfer position by the first winch 220, and then the working device 1000 is transferred from the transfer position to the A-type hanger 250 by the crane 240, which reduces the suspended distance of the working device 1000 and improves the safety factor of the working device 1000 during the transfer process; at the same time, the cooperation between the first winch 220 and the transfer position also improves the convenience of dragging the working device 1000 out of the deckhouse 210.

[0040] In other embodiments, the working device 1000 can be lifted out of the deckhouse 210 by the crane 240. In this embodiment, the first opening 211 needs to be opened on the top of the deckhouse 210. This arrangement can save the first winch 220, save costs, reduce operating procedures, and improve deployment efficiency.

[0041] The A-type cradle 250 is disposed at the stern of the mother ship 100, the deckhouse 210 is disposed at the head of the mother ship 100, and the crane 240 is located between the A-type cradle 250 and the deckhouse 210. Specifically, from the front to the rear, the deckhouse 210, the transfer position, the crane 240 and the A-type cradle 250 are disposed in sequence. The above layout rationally utilizes the structure of the mother ship 100 itself. Under the premise that the lifting arm of the crane 240 is as short as possible, the working end of the crane 240 can cover the vicinity of the deck house 210 at the head of the mother ship 100 and the vicinity of the A-type hanger 250 at the tail of the mother ship 100, that is, the transfer of the operating device 1000 between the head and tail of the entire mother ship 100 can be completed, thereby reducing costs. At the same time, the operating device 1000 is placed at the head of the mother ship 100, which can be as far away from the A-type hanger 250 as possible, thereby avoiding interference with the A-type hanger 250 when lifting other goods, thereby improving safety. Finally, the operating device 1000 can also play a certain counterweight role when the A-type hanger 250 lifts other goods, which is beneficial to the front and rear balance of the mother ship 100.

[0042] It is worth noting that the head of the mother ship 100 is the front part, the tail of the mother ship 100 is the rear part, the length direction of the mother ship 100 is the front-to-back direction, the width direction of the mother ship 100 is the left-to-right direction, and the height direction of the mother ship 100, the length direction of the mother ship 100 and the width direction of the mother ship 100 are perpendicular to each other.

[0043] In this embodiment, the first opening 211 is located at the rear side of the deckhouse 210, that is, the first opening 211 is opened rearward. The above arrangement enables the working device 1000 to move backward after being moved out of the deckhouse 210, that is, the distance between the working device 1000 and the A-type hanger 250 is shortened, thereby improving the deployment efficiency of the working device 1000.

[0044] In order to make the transfer position as close as possible to the base 241 of the crane 240, in this embodiment, the first winch 220 is arranged at the first installation position of the deck 110, the base 241 of the crane 240 is provided with a first fixed pulley 242, and the first installation position is located on the left side of the line between the first fixed pulley 242 and the first opening 211. The above arrangement enables the transfer position to be located near the base 241 of the crane 240; in other words, the transfer position can be set at a position close to the base 241 of the crane 240, and the transfer process of the working device 1000 will not be hindered by the first winch 220. The above arrangement minimizes the distance that the working device 1000 is suspended, thereby minimizing the risk of the transfer process of the working device 1000.

[0045] The traction rope 243 passes through the first fixed pulley 242, and one end is fixedly connected to the working device 1000, and the other end is connected to the winding wheel on the first winch 220. When the winding wheel of the first winch 220 rotates, the traction rope 243 is wound, and the working device 1000 is dragged out of the deck house 210. The traction rope 243 is arranged at an angle, and the angle α of the traction rope 243 is less than 90 degrees along the forward direction with the first fixed pulley 242 as the vertex. The above arrangement avoids interference between the first winch 220 and the traction rope 243, and reduces the occupation of the deck 110 as much as possible during the traction process.

[0046] In some embodiments, the first winch 220 is detachably mounted at the first mounting position of the deck 110. The above arrangement allows the first winch 220 to be temporarily mounted at the first mounting position when the working device 1000 is dragged to the transfer position, and can be removed after the working device 1000 is transferred to the transfer position, thereby avoiding occupying the deck 110 and effectively improving the utilization rate of the deck 110.

[0047] To protect the working device 1000, in some embodiments, the mother ship 100 further includes a first door, which can open or close the first opening 211. The above arrangement enables the working device 1000 to be enclosed in the deckhouse 210, thereby improving the safety of the working device 1000 during storage.

[0048] In some embodiments, the deckhouse 210 is provided with a second opening 212, the second winch 230 is arranged in the deckhouse 210, the umbilical cable 231 passes through the second opening 212 and is connected to the working device 1000, and the opening direction of the second opening 212 is different from the opening direction of the first opening 211. The above arrangement can make the passing direction of the umbilical cable 231 away from the crane 240, thereby avoiding the interference of the crane 240 with the umbilical cable 231. The opening area of ​​the first opening 211 is larger than the opening area of ​​the second opening 212. The first opening 211 is used to transfer the working device 1000 and needs to have a larger size; while the umbilical cable 231 is smaller in size and does not need to occupy the larger first opening 211, and only needs to pass through the second opening 212; after the deployment is completed, the first opening 211 can be closed to avoid the larger first opening 211 from swinging back and forth and being damaged.

[0049] Exemplarily, the deckhouse 210 is located at the right part of the head of the mother ship 100, and the second opening 212 is opened to the left. In other words, the mother ship 100 is provided with a central axis 120 extending in the front-rear direction, and the deckhouse 210 is located on the deck 110 and is located on the right side of the central axis 120. The above-mentioned orientation setting enables the umbilical cable 231 to pass through the second opening 212 and reach the A-type hanger 250 at the shortest distance on the basis of bypassing the crane 240, thereby reducing the length of the umbilical cable 231. The height of the second opening 212 is lower than the preset height. Among them, the preset height can be 100mm.

[0050] The mother ship 100 further includes a second door, which is used to open or close the second opening 212. The second door is rotated 180° from a closed position for closing the second opening 212 to an open position for opening the second opening 212. When the second door is in the closed position, it is locked by a door lock. When the second door is in the open position, it is held in the open position by magnetic attraction. A magnet is provided on the side wall of the deckhouse 210, and at least a portion of the second door is made of stainless steel or iron.

[0051] In this embodiment, the second winch 230 is located in the deckhouse 210. The above arrangement can protect the second winch 230 and the umbilical cable 231 wound thereon, thereby improving the service life. The second winch 230 includes a winding wheel, and the umbilical cable 231 is wound on the winding wheel, and the axis of the winding wheel extends in the front-to-back direction. In some embodiments, the deckhouse 210 includes a first placement area and a second placement area, the first placement area is located on the left side of the second placement area, and in the front-to-back direction, the first opening 211 is opposite to the first placement area, the first placement area is used to place the working device 1000, and the second placement area is used to place the second winch 230. In other words, the second winch 230 is located on the right side of the working device 1000.

[0052] In order to ensure that the umbilical cable 231 can move smoothly after turning and avoid scratching, in some embodiments, the deep-sea towing and laying system includes a first guide 260, which is located on the left side of the deckhouse 210 and between the deckhouse 210 and the A-type hanger 250 in the front-back direction. The first guide 260 is used to guide the umbilical cable 231 from the width direction of the mother ship 100 to the length direction of the mother ship 100. In this embodiment, the first guide 260 includes a first roller, the axis of the first roller extends in the vertical direction, and the umbilical cable 231 from right to left is wound around the first roller and extends backward. The vertical direction is the height direction of the mother ship 100, that is, the up and down direction. Exemplarily, the first guide 260 includes a guide pulley. The above arrangement enables the umbilical cable 231 to turn, and the rolling friction between it and the first roller can reduce wear as much as possible and increase life; at the same time, it avoids wear on the structure of the mother ship 100.

[0053] The first guide member 260 is detachably mounted on the deck 110 of the mother ship 100. This arrangement enables the first guide member 260 to be installed on the deck 110 only when the operating device 1000 is in use, and can be removed and stowed at other times to avoid occupying the deck 110. Furthermore, the first guide member 260 is variably mounted on the deck 110. This arrangement can effectively plan the path of the umbilical cable 231 to avoid interference with the mechanism on the deck 110. Specifically, the deck 110 is provided with a plurality of mounting holes arranged in a matrix, and the mounting screws are passed through the fixing holes of the first guide member 260 and then screwed into one of the plurality of mounting holes.

[0054] The deep-sea towing and laying system includes a second guide 270, which is arranged on the deck 110 and is located between the first guide 260 and the A-type hanger 250. The second guide 270 is used to guide the umbilical cable 231 from the length direction of the mother ship 100 to the height direction of the mother ship 100. In this embodiment, the second guide 270 includes a second roller, the axis of the second roller extends along the width direction, and the umbilical cable 231 from front to back bypasses the circumference of the second roller and extends upward. Further, the first guide 260 and the second guide 270 have the same height. The above arrangement makes the umbilical cable 231 between the first guide 260 and the second guide 270 parallel and close to the deck 110, avoiding the umbilical cable 231 between the first guide 260 and the A-type hanger 250 from being tilted in the air, thereby improving safety. In other words, the provision of the second guide member 270 makes the distance between the umbilical cable 231 and the deck 110 between the first guide member 260 and the second guide member 270 closer, thereby avoiding the risk of interception of pedestrians or other organizations on the deck 110.

[0055] In some embodiments, a protective cover may be further provided, the protective cover being mounted on the deck 110 , and the umbilical cable 231 between the first guide member 260 and the second guide member 270 being covered in the protective cover. The protective cover may be detachably mounted on the deck 110 . The protective cover may be placed in the deckhouse 210 .

[0056] Regarding the structure of the A-type hanger 250, in some embodiments, the A-type hanger 250 includes a boom 251, a pulley frame 252, a second fixed pulley 253 and a driving member 254, wherein one end of the boom 251 is rotatably disposed on the deck 110 of the mother ship 100; the pulley frame 252 is disposed at the other end of the boom 251; the second fixed pulley 253 is rotatably disposed on the pulley frame 252; the driving member 254 is disposed on the deck 110, and the driving member 254 is used to drive the boom 251 to transfer between the initial position and the working position. When the boom 251 is located at the initial position, the operating device 1000 on the boom 251 is located above the mother ship 100, and when the boom 251 is located at the working position, the operating device 1000 on the boom 251 is located behind the mother ship 100. During operation, the umbilical cable 231 passes around the second fixed pulley 253. The above arrangement can transfer the operating device 1000 from above the mother ship 100 and behind the mother ship 100, and under the action of the second winch 230, release the operating device 1000 to the deep sea or tow it out from the deep sea.

[0057] In some embodiments, the A-type hanger 250 further includes a hook 255, which is disposed at the other end of the hanger 251, and the pulley frame 252 is hooked on the hook 255. The above arrangement makes the connection between the pulley frame 252 and the hanger 251 more convenient, thereby improving the deployment efficiency of the working device 1000. In this embodiment, when the hanger 251 is in the initial position, the hook 255 is located on the mother ship 100, and when the hanger 251 is in the working position, the hook 255 is located behind the mother ship 100.

[0058] It should be noted that the structure and working principle of the driving member 254 driving the boom 251 and the structure and working principle of the crane 240 are well known to those skilled in the art and are not the content of this application, so they will not be described here.
