Description

Technical Field

[0001] The present application relates to the field of ships, and in particular to a positioning and deployable cable-dropping system. Background Art

[0002] When a ship is sailing at sea for lateral replenishment, docking at a dock, or working alongside other ships, it is necessary to perform cable-laying operations: that is, when the ship is far away from the supply ship or dock, the towline is thrown to the supply ship or dock to pull the thicker cable for subsequent operations. In the past, when using a cable-laying gun to lay the cable, it was impossible to control the landing point of the cable head on the other ship or dock. For supply ships with more deck facilities, it would cause difficulty in finding or the rope would be entangled with the facilities, prolonging the time to collect the cable. In addition, the cable-laying gun has a large impact force when launching the cable head. When the cable head falls instantly, it may damage the equipment on the ship or hit nearby workers and cause injuries. All of these bring great risks and inconveniences to the cable-laying operation. Summary of the invention

[0023] The features and performance of the positionable cable-dropping system of the present application are further described in detail below in conjunction with the embodiments.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, the embodiment of the present application provides a positioning and launching cable system, which includes a constant tension winch 100, a cable 110 connected to and wound around the constant tension winch 100 at one end, an auxiliary rope 120, an unmanned aerial vehicle 200 and a remote controller 130, the unmanned aerial vehicle 200 is connected to a first connecting ring 250 and a second connecting ring 260 through a cable release device, the auxiliary rope 120 and the cable 110 are respectively connected to a shackle 280 detachably connected to the first connecting ring 250 and the second connecting ring 260 through a rope head 270, the other end of the auxiliary rope 120 is connected to the cable 110, a section of the cable 110 connected to the corresponding rope head 270 is a retractable buffer spring 290, and the cable release device is used to selectively connect or separate the first connecting ring 250 and the second connecting ring 260;

[0025] The cable release device includes a first electromagnet control module 201 and a second electromagnet control module 202 connected to the UAV aircraft 200, the first electromagnet control module 201 and the second electromagnet control module 202 are respectively connected to the first electromagnet 210 and the second electromagnet 220, the first electromagnet 210 and the second electromagnet 220 are respectively adsorbed with the first magnetic movable seat 230 and the second magnetic movable seat 240 through magnetic force, the first magnetic movable seat 230 and the second magnetic movable seat 240 are respectively connected with the first connecting ring 250 and the second connecting ring 260, the first electromagnet control module 201 and the second electromagnet control module 202 are respectively used to control the first electromagnet 210 and the second electromagnet 220 to be magnetically adsorbed or separated from the first magnetic movable seat 230 and the second magnetic movable seat 240.

[0026] The UAV aircraft 200 has four propellers 300 that can rotate around a vertical axis, and the UAV aircraft 200 is connected to a propeller grille cover 310 that covers the outer sides of the corresponding propellers 300. The remote controller 130 is used to send control instructions to the first electromagnet control module 201 and the second electromagnet control module 202 to control the first electromagnet 210 and the second electromagnet 220 to magnetically attract or separate from the first magnetic attraction movable seat 230 and the second magnetic attraction movable seat 240.

[0027] When the locatable cable-dropping system provided in the embodiment of the present application is used, the auxiliary rope 120 and the cable-dropping rope 110 are connected to the first connecting ring 250 and the second connecting ring 260 connected to the UAV aircraft 200 through the shackle 280 connected to the rope head 270, respectively, and the first electromagnet control module 201 and the second electromagnet control module 202 are used to energize the first electromagnet 210 and the second electromagnet 220 respectively, so that the first magnetic movable seat 230 and the second magnetic movable seat 240 connected to the first connecting ring 250 and the second connecting ring 260 are magnetically attracted to the first electromagnet 210 and the second electromagnet 220 respectively, thereby suspending and fixing the auxiliary rope 120 and the cable-dropping rope 110 below the UAV aircraft 200 At this time, the end of the sling cable 110 away from the UAV aircraft 200 is connected to and wound around the drum of the constant tension winch 100 on the cable sending ship 400, and then the tension value of the constant tension winch 100 is adjusted according to the actual environmental conditions during the operation. When the environmental conditions are bad, the tension value of the constant tension winch 100 can be adjusted to a high value, so that the auxiliary rope 120 and the sling cable 110 carried by the UAV aircraft 200 are always kept in a state of having a certain tension, so as to prevent the UAV aircraft 200 from being disturbed by the rope shaking or being entangled by too much released rope during the flight, so that the UAV aircraft 200 can fly to the preset position above the cable receiving ship 500 without being disturbed by the rope shaking under strong wind force, and the operator at the release location can release the rope. A universal remote controller 130 is used to send a control command to the first electromagnet control module 201. The first electromagnet control module 201 controls the first electromagnet 210 to be powered off, so that the first magnetic movable seat 230 is separated from the first electromagnet 210, thereby causing the first connecting ring 250 connected to the first magnetic movable seat 230 to fall down, and the auxiliary rope 120 connected to the first connecting ring 250 to fall down and be released together. The operator disassembles the shackle 280 connected to the first connecting ring 250 to remove the separated auxiliary rope 120, and then fixes the auxiliary rope 120 to the cable receiving ship 500 nearby. Then the operator uses the remote controller 130 to send a control command to the second electromagnet control module 202 in the same way. The second electromagnet control module 202 controls the second electromagnet 220 to be powered off, so that the second magnetic movable seat 240 is separated from the second electromagnet 220, so that the second connecting ring 260 connected to the second magnetic movable seat 240 falls down, and the slinging cable 110 connected to the second connecting ring 260 falls down and is released. The operator disassembles the shackle 280 connected to the second connecting ring 260 and removes the detached slinging cable 110 to fix it, and then the auxiliary rope 120 and the slinging cable 110 connecting the cable sending ship 400 and the cable receiving ship 500 can be used to carry out subsequent cable pulling operations. When the pulling operation is completed, the auxiliary rope 120 and the slinging cable 110 can be fixed to the first connecting ring 250 and the second connecting ring 260 respectively through the shackle 280 connected to the rope head 270.The first electromagnet 210 and the second electromagnet 220 are controlled to electromagnetically absorb the first magnetic movable seat 230 and the second magnetic movable seat 240 respectively, and then the auxiliary rope 120 and the cable 110 are sent back to the cable sending ship 400 by using the unmanned aerial vehicle 200.

[0028] Among them, the method of first releasing the auxiliary rope 120 and fixing it, and then releasing the sling cable 110 can prevent the sling cable 110 with constant tension from rebounding due to the constant tension not disappearing when it is released, which makes it difficult to fix. The unmanned aerial vehicle 200 is provided with a propeller grid cover 310 that covers the outer side of the corresponding propeller 300. The propeller grid cover 310 can be used to protect the propeller 300 to prevent the auxiliary rope 120 and the sling cable 110 from being blown up and wound inside the propeller 300 of the unmanned aerial vehicle 200 in strong winds, causing damage to the unmanned aerial vehicle 200; the section connecting the sling cable 110 and the corresponding rope head 270 is a retractable buffer spring 290, which can use the elastic potential energy of the buffer spring 290 to buffer the constant tension of the sling cable 110, ensuring that it plays a buffering role when the response speed of the constant tension winch 100 is insufficient.

[0029] In addition, the UAV aircraft 200 can also fly to the preset position of the cable receiving ship 500 to manually cut off the power of the first electromagnet 210 and the second electromagnet 220, and remove the auxiliary rope 120 and the cable rope 110 in turn and fix them to the cable receiving ship 500.

[0030] Before releasing the auxiliary rope 120 and the rope end 270 of the sling rope 110, the constant tension mode of the constant tension winch 100 can be disconnected and the ordinary winch mode can be adopted according to the situation. When manual cable release operation is adopted, the constant tension mode of the constant tension winch 100 is usually switched to the ordinary mode first.

[0031] The embodiments described above are part of the embodiments of the present application, rather than all of the embodiments. The detailed description of the embodiments of the present application is not intended to limit the scope of the present application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.
