Description

Technical Field

[0001] The invention belongs to the technical field of marine engineering equipment, and in particular relates to a long-length cable storage device for a seawater corrosion-resistant ocean buoy and a storage and recovery method. Background Art

[0002] The ocean is the cradle of life and a valuable asset for the sustainable development of human society. At present, with the increasing severity of land resource shortages, population expansion, environmental degradation and other problems, coastal countries have turned their attention to the ocean and accelerated the development and utilization of the ocean. However, facing the vast ocean, once the exploration equipment fails, it will become difficult to find it. In order to avoid the disadvantage of being unable to find and rescue, the underwater equipment itself will have a buoy device for positioning and communicating with the outside world. Once the equipment fails, it will actively release the buoy device to communicate with the outside world and send the location to achieve rescue.

[0003] The prior art has the following defects: 1. The cable connected to the buoy device is stored in an arc-shaped cable storage device (whose cross-section is an ellipse of varying sizes), which is relatively large in size and needs to be placed in the underwater equipment before the underwater equipment is capped. Therefore, if the underwater equipment has been capped, the cable storage device cannot be placed in the underwater equipment; 2. After the arc-shaped cable storage device is placed in the underwater equipment, one end of the cable passes through the top cover of the arc-shaped cable storage device in turn, passes through the guide device under the top plate of the underwater equipment, and is connected to the buoy. At this time, the gap between the top cover of the arc-shaped cable storage device and the top plate of the underwater equipment is reduced, resulting in a smaller movement space. Therefore, when the operator drags the cable, the operation is inconvenient, and the cable cannot be recovered without damaging the top plate. Summary of the invention

[0004] The purpose of the present invention is to provide a long-length cable storage device for seawater corrosion-resistant ocean buoys and a storage and recovery method. When the underwater equipment is capped, the cable storage device can be placed into the equipment through a narrow operating space and assembled, and the cable can be quickly recovered without destroying the structure of the underwater equipment. The adopted technical solution is as follows:

[0005] A long-length cable storage device for a seawater corrosion-resistant ocean buoy, comprising:

[0006] The side plate comprises a plurality of sub-side plates which are distributed along the circumference and spliced ​​in sequence; an arc-shaped gap for releasing the rope is formed between the first sub-side plate and the last sub-side plate, and adjacent sub-side plates are detachably connected;

[0007] The lower base and the upper cover are detachably connected to the bottom surface and the top surface of the side plate respectively;

[0008] The cables are stacked in layers in the stacking space surrounded by the sub-side plates, and one end of the cables passes through the arc gap between the first sub-side plate and the last sub-side plate and is connected to the buoy; an operating space for installing a cable storage device is provided in the underwater equipment, and the operating space is connected to the seawater environment.

[0009] Preferably, each of the sub-side panels is folded outward to form a first curling edge extending in the height direction and a second curling edge extending in the circumferential direction;

[0010] Except for the curling edge 1 that encloses the arc-shaped gap, the other curling edges are installed with double bolts and nuts for connecting adjacent sub-side panels.

[0011] Preferably, the curling edges of the first sub-side panel and the last sub-side panel that enclose the arc-shaped gap are both arc-shaped and smooth.

[0012] Preferably, the lower base and the bottom surface of the side plate, and the upper cover plate and the top surface of the side plate are connected by double bolts and nuts, and the upper ends of all the sub-side plates are curled twice to form the top surface of the side plate; the lower ends of all the sub-side plates are curled twice to form the bottom surface of the side plate;

[0013] Preferably, the sub-side plates are arc-shaped, the stacking space enclosed by the sub-side plates is cylindrical, and the outer ring of the cable is in contact with the inner wall of the sub-side plates.

[0014] Preferably, two cross-shaped reinforcing ribs are welded on the upper cover plate, and one of the reinforcing ribs is located at a middle position just above the arc-shaped gap of the side plate.

[0015] Preferably, the sub-side plate, upper cover plate and lower base are all made of 316L corrosion-resistant material.

[0016] A method for storing a long-length storage cable for a seawater corrosion-resistant ocean buoy includes the steps of storing the cable, specifically:

[0017] Step 1: Mechanical equipment hoists the cables, all sub-side panels, lower base and upper cover into the operating space;

[0018] Step 2: The operator enters the operating space;

[0019] Step 3: The operator stacks the cables in layers on the lower base;

[0020] Step 4: The operator splices the sub-side panels, and then installs the lower base and upper cover;

[0021] Step 5: Pass the cable through the arc gap between the first sub-side plate and the last sub-side plate and connect it to the buoy. Finally, rely on the buoyancy of the buoy to pull it out and release it.

[0022] Preferably, the method further includes the step of recycling the cables, specifically:

[0023] In the operating space, the operator pulls the cables into the stacking space at the arc gap, and the cables are re-stacked in layers under the constraints of the inner wall of the side plate;

[0024] Or in the operating space, the operator removes the upper cover, the first sub-side panel or one of the last sub-side panels, and then pulls the cables into the stacking space. The cables are restacked in layers under the constraints of the inner walls of the side panels, and then the side panels and upper cover are reinstalled after completion.

[0025] Compared with the prior art, the advantages of the present invention are:

[0026] 1. When the underwater equipment is capped, enter the equipment through a narrow operating space and assemble the cable storage device.

[0027] 2. The cables can be quickly recovered without damaging the structure of the underwater equipment.

[0028] 4. Reliable wire storage and release, large internal storage: two of the three side panels have openings on one side, and the openings are curved and rolled outwards, and are smooth and polished without edges and corners, making it easy for the internal cables to be pulled out and released without being damaged by edges and corners;

[0029] The internal cylindrical barrel structure adopts stacked cable storage. The cables are regularly stacked layer by layer in the stacking space, which can effectively occupy the internal space. The storage capacity is larger than the pot-shaped structure in the prior art. The cables are released from the opening of the side panel through tensile stress. The stacking structure will not cause the cables to fail to release due to internal compression and stacking.

[0030] In the prior art, the iron pot-shaped cable storage structure has a large upper opening and an inward-curved bottom. In order to ensure that the cables are not stacked and effectively released during the process of paying out the cables above the pot, a circle-staggered plum blossom-shaped layer-laying method is also adopted when storing the cables. The cables are placed loosely, and the upper opening is large and the storage capacity is large, while the lower storage capacity is small. The pot-shaped upper opening also needs to have a certain cable release channel with the underwater equipment. Therefore, the pot-shaped cable storage device cannot fully utilize the entire height of the underwater equipment space, and the storage capacity cannot be fully utilized in the same cylindrical space, and the storage capacity is small.

[0031] 5. Easy installation and transportation, no resonance noise: The split structure is easy to disassemble, assemble and transport, and requires less space. When the cable is installed in the side panel, the pre-formed cable stack can be hoisted into the machine as a whole, or the side panel can be installed directly after the cable is arranged and stored on the base of the split barrel. It is suitable for operation, installation and transportation in narrow spaces without destroying the original spatial structure of the underwater equipment. The overall thickened structure is adopted, and the side panels and the side panels and the upper and lower cover panels are fastened with multi-hole nuts and bolts, double nuts are fastened, and the upper cover panel is suspended with reinforcement ribs, which can effectively avoid the resonance and sound of the upper cover panel, the side wall of the cable storage device and the underwater equipment, which will affect the underwater navigation and expose the position of the submersible.

[0032] 6. Tight structure and reliable storage: The whole is made of 316L stainless steel, which is resistant to seawater corrosion and can be stored in seawater environment for a long time. The whole adopts thickened structure and is fastened with multi-hole double nuts and bolts. The double nuts are fastened to prevent the screws from loosening due to equipment vibration, and the storage is reliable. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following will be described in more detail with reference to the schematic diagram of the present invention for a long-length cable storage device for a seawater corrosion-resistant ocean buoy and the storage and recovery method, wherein preferred embodiments of the present invention are shown, and it should be understood that those skilled in the art can modify the present invention described herein while still achieving the advantageous effects of the present invention. Therefore, the following description should be understood as being widely known to those skilled in the art and not as a limitation of the present invention.

[0039] like Figures 1 to 5 , A long-length cable storage device for seawater corrosion-resistant ocean buoys, including: the sub-side plate, upper cover plate and lower base are all made of 316L corrosion-resistant material, which can be reliably stored in seawater environment for a long time. ,

[0040] The side plate comprises a plurality of sub-side plates which are distributed along the circumference and spliced ​​in sequence; an arc-shaped gap for releasing the rope is formed between the first sub-side plate and the last sub-side plate, and adjacent sub-side plates are detachably connected.

[0041] Specifically, each sub-side plate is folded outward to form a first curling edge extending in the height direction and a second curling edge extending in the circumferential direction;

[0042] Except for the curling edge 1 that forms the arc-shaped gap, the other curling edges 1 are equipped with double bolts and nuts for connecting adjacent sub-side panels. According to the prior art, during installation, the bolts in the double bolts and nuts are passed through two adjacent curling edges 1, and then the two nuts are screwed onto different threaded sections of the double bolts respectively.

[0043] The first sub-side plate and the last sub-side plate have curved edges that enclose the curved gap, and are smooth surfaces. That is, the curved edges are smooth and polished without edges and corners, so that the internal cables can be pulled out and released without being damaged by the edges and corners.

[0044] The lower base and the upper cover are detachably connected to the bottom and top surfaces of the side panels, respectively. Figure 3 , Figure 5 As shown, the upper cover plate and the lower base are flush with the outer edges of the side plates.

[0045] Among them, the lower base plate is 10mm thickened 316L steel plate.

[0046] like Figure 3 , Figure 5 As shown, double bolts and nuts are used to connect the lower base and the bottom surface of the side plate, and the upper cover and the top surface of the side plate.

[0047] Specifically, the double bolts and nuts are both installed on the curling edge 2 extending outward from the side plate and the curling edge extending outward from the lower base, so the fasteners do not affect the stability of the entire device.

[0048] The circular holes are all on the outer curled edge of the inner cylinder. Each sub-side panel is fixed by nearly 4 screws, and the sub-side panels are also fixed by three to four screws from top to bottom. The three side panels are locked and supported with each other. After installation, the whole is very firm, which can prevent resonance and noise from underwater equipment.

[0049] The second curling edge at the upper end of all the sub-side panels forms the top surface of the side panel; the second curling edge at the lower end of all the sub-side panels forms the bottom surface of the side panel.

[0050] That is, a mounting hole is provided on the second curling edge for mounting the bolt in the double-bolt nut.

[0051] The cables are stacked in layers in the stacking space surrounded by the sub-side plates, and one end of the cables passes through the opening on the top plate of the underwater equipment and is connected to the buoy; an operating space for installing a cable storage device is opened in the underwater equipment, and the operating space is connected to the seawater environment.

[0052] The sub-side plates are arc-shaped, the stacking space surrounded by the sub-side plates is cylindrical, and the outer ring of the cable is in contact with the inner wall of the sub-side plates.

[0053] Two cross-shaped reinforcing ribs are welded on the cover plate, and one of the reinforcing ribs is located at the middle position just above the arc-shaped gap of the side plate.

[0054] After the underwater engine is started, the vibration of the entire equipment can easily cause the suspended upper cover to resonate. This design effectively enhances the overall strength of the upper cover and avoids resonance that causes noise and exposes the position of the submersible.

[0055] That is, the suspended position of the upper cover plate is provided with reinforcing ribs, which can effectively prevent the suspended position, the side walls of the cable storage device and the underwater equipment from resonating and emitting sound, affecting underwater navigation and exposing the position of the submersible.

[0056] Specifically, the reinforcement bar is a 6mm thick 316L steel strip.

[0057] A method for storing a long-length storage cable for a seawater corrosion-resistant ocean buoy comprises the steps of storing the cable, releasing the cable and recovering the cable.

[0058] The steps for storing cables are as follows:

[0059] Step 1: Mechanical equipment hoists the cables, all sub-side panels, lower base and upper cover into the operating space;

[0060] Alternatively, because it is a split structure, each component has a moderate weight, and when the equipment is inconvenient to operate, it can also be carried in manually;

[0061] Step 2: The operator enters the operating space;

[0062] Step 3: The operator stacks the cables in layers on the lower base;

[0063] Step 4: The operator splices the sub-side panels, and then installs the lower base and upper cover;

[0064] Step 5: Pass the cable through the arc gap between the first sub-side plate and the last sub-side plate and connect it to the buoy. Finally, the buoy is towed out and released by the buoyancy of the buoy, that is, the buoy is released from the operating space to the marine environment.

[0065] In addition, the following steps can also be used in steps 3 to 4:

[0066] The operator splices the sub-side panels and then installs the lower base;

[0067] Afterwards, the operator hoists the layered wire stack as a whole into the stacking space surrounded by the sub-side plate and the lower base for placement;

[0068] Finally install the cover.

[0069] To release the cable, follow these steps:

[0070] The cables are released from the arc gap by tensile stress. The stacked structure will not cause the cables to be stacked up inside and cause release failure.

[0071] The steps for recycling cables are as follows:

[0072] In the operating space, the operator pulls the cables into the stacking space at the arc gap, and the cables are re-stacked in layers under the constraints of the inner wall of the side plate;

[0073] Or when operation is inconvenient, in the operation space, the operator removes the upper cover plate, the first sub-side plate or one of the last sub-side plates, and pulls the cables into the stacking space. The cables are restacked in layers under the constraints of the inner walls of the side plates, and then the side plates and upper cover plate are reinstalled after completion.

[0074] Specifically, during recycling, the cables fall down along the inner wall of the side plate until they are stacked on the previous circle of cables.

[0075] The operator moves at the arc gap, and his movement space is the entire operation space. Therefore, compared with the existing technology, his movement space is large and the cable recovery can be completed smoothly.

[0076] The above is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any technician in the relevant technical field, without departing from the scope of the technical solution of the present invention, makes any form of equivalent replacement or modification to the technical solution and technical content disclosed in the present invention, which does not depart from the content of the technical solution of the present invention and still falls within the protection scope of the present invention.
