Abstract
Description
Technical Field
[0001] The utility model belongs to the field of underwater monitoring equipment, in particular to a clamp underwater floating device. Background Art
[0002] In jacket-type offshore platforms, clamp-type underwater fixtures are widely used for the installation of underwater monitoring equipment during offshore oil development and seabed drilling. The jacket has a large outer size, so it requires a large clamp to fix it, which makes the clamp relatively heavy. When installing such a large clamp on the jacket underwater, it is usually necessary to use the buoyancy of the float to support and stabilize the clamp.
[0003] In the current technical solution, multiple floats are usually required to support the clamp. These floats are connected to the clamp by at least two cables. Although this multi-float support system can provide sufficient buoyancy, the recovery operation of the floats after the clamp is installed is quite cumbersome. In order to recover these floats, it is necessary to cut the cables connecting the floats and the clamp one by one. This not only increases the complexity of the operation, but also increases the risk and time cost of underwater operations. Utility Model Content

[0006] There are multiple floating bodies, each of which is connected to at least two supporting cables, and a connecting seat is installed at one end of the supporting cables away from the floating body;
[0007] A fixing seat is mounted on the clamp body and is arranged in plurality along the circumference of the clamp body;
[0008] Only one connecting cable is provided, both ends of which are connected to the clamp body. The connecting cable extends from one side of the opening along the clamp body to the other side of the opening, and passes through the fixing holes set in each fixing seat and the connecting holes set in each connecting seat in the process of extending.

[0010] In some of the embodiments, a cable support sleeve is sleeved on the connecting cables between adjacent fixing seats. The cable support sleeve is arc-shaped and is located on the circumference of the clamp body.
[0011] In some of the embodiments, the cable support sleeve is a rubber hose.
[0012] In some of the embodiments, the cable support sleeves are connected to the corresponding floating bodies above through connecting lines.
[0013] In some of the embodiments, the end of the cable support sleeve has a positioning plug, which is inserted into the corresponding fixing hole and / or connecting hole.
[0014] In some of the embodiments, when the end of the connecting cable extends toward the opening, it passes through a fixing ring installed on the clamp body and is fixedly connected to the limited end.
[0015] In some embodiments, the connecting cable is a rubber band rope and is in a stretched state.

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0028] like Figure 1 to Figure 2As shown, in an illustrative embodiment of the clamp underwater floating device of the utility model, the clamp underwater floating device is installed on an annular clamp body 1, and one side of the clamp body 1 has an opening 11 that can be opened and closed. When the opening 11 of the clamp body 1 is opened, the catheter frame enters the clamp body 1 laterally through the opening 11. The two ends of the clamp body 1 are fixedly connected by the installed fasteners 2, so that the opening 11 is closed, and the clamp body 1 is tightly clamped on the catheter frame, so that the monitoring equipment fixed to the clamp body 1 by the set mounting seat is stably fixed underwater. In order to realize the opening 11 of the clamp body 1, the clamp body 1 can be deformed, or the clamp body 1 can be set as a multi-section hoop plate 12 structure with hinged connection.
[0029] The clamp underwater floating device comprises a float 3, a fixing seat 4 and a connecting cable 5.
[0030] There are multiple floating bodies 3, each of which is connected to at least two supporting cables 6, and a connecting seat 7 is installed at one end of the supporting cables 6 away from the floating body 3. The fixing seat 4 is installed on the clamp body 1, and multiple fixing seats 4 are arranged along the circumference of the clamp body 1. The fixing seats 4 are all provided with fixing holes, and only one connecting cable 5 is provided, one end of which is connected to the clamp body 1 and is located on one side of the opening 11, and the other end of the connecting cable 5 passes through the fixing holes of each fixing seat 4 in turn along the circumference of the clamp body 1, and finally connected to the clamp body 1 on the other side of the opening 11.
[0031] In the process of extending the connecting cable 5 from one end to the other end, it not only passes through the fixing holes of each fixing seat 4, but also passes through the connecting holes provided in each connecting seat 7. The buoyancy generated by the floating body 3 acts on the connecting cable 5 through the connecting seat 7 supporting the cable 6, and further acts directly on the clamp body 1 through the connecting cable 5 or indirectly on the clamp body 1 through the fixing seat 4, so that the buoyancy generated by all the floating bodies 3 acts on the clamp body 1, and the total buoyancy is the same as the weight of the clamp body 1, so that the clamp body 1 is in a suspended state underwater, which is convenient for divers or ROVs to move and install the clamp body 1.
[0032] The buoyancy of each float 3 needs to be transmitted to each angular position on the circumference of the clamp body 1 through the support cable 6, so as to fully support the clamp body 1 and make the clamp body 1 float stably underwater. Due to the insertion of the connecting cable 5, the connecting seat 7 needs to be laid along the connecting cable 5, and the fixing seat 4 constrains the connecting cable 5 so that it is arranged along the clamp body 1, so that the connecting seat 7 is arranged along the clamp body 1 and distributed at various angular positions on the circumference of the clamp body 1, so as to achieve full support of the clamp body 1.
[0033] After the clamp body 1 is fixed to the conductor frame, the diver manually cuts the connecting cable 5, or uses the ROV to cut the connecting cable 5, and the connecting cable 5 will lose its restraint. The buoyancy of the floating body 3 pulls the connecting seat 7 upward through the supporting cable 6, and the connecting cable 5 that loses its restraint is pulled out of the connecting hole and the fixing hole, eliminating the support connection of the fixing seat 4 to the connecting seat 7 through the connecting cable 5, so that the floating body 3 can float to the surface of the water by itself, so as to be recovered. Since there is only one connecting cable 5, the connecting cable 5 strings all the connecting seats 7, and cutting the connecting cable 5 can make all the connecting seats 7 free from the restraint of the connecting cable 5. As the floating body 3 floats up, the connecting cable 5 is pulled out of each fixing hole and each connecting hole, so that all the floating bodies 3 can be floated and recovered.
[0034] In the above-mentioned schematic embodiment, the clamp underwater floating device realizes the connection between all the floats 3 and the clamp body 1 through a connecting cable 5 fixed and looped on the clamp body 1. Therefore, after the clamp body 1 is installed, the connection of all the floats 3 can be eliminated by cutting the connecting cable 5, and the floats 3 can be quickly dismantled and recovered underwater, which improves the underwater operation efficiency, reduces the underwater operation time, avoids the risk increase caused by too long underwater operation time, and solves the problem that the current clamp floating structure needs to cut the cables one by one to recover the floats 3, which causes complicated operation and increased underwater risks.
[0035] In some embodiments, the connecting seat 7 has two connecting plates 71, each fixing seat 4 is located between the two connecting plates 71 of the corresponding connecting seat 7, both connecting plates 71 are provided with connecting holes, and the connecting cable 5 passes through the fixing holes of the fixing seat 4 and the two connecting holes of the corresponding connecting seat 7.
[0036] Under the constraint of the connecting cable 5, the fixing seat 4 cannot vertically escape from the connecting seat 7, so that it remains between the two connecting plates 71, so that the fixing seat 4 forms a circumferential constraint on the connecting seat 7 through the two connecting plates 71, and the connecting seat 7 cannot move along the connecting cable 5, so that it remains aligned with the fixing seat 4. The connecting seat 7 is fully distributed at various angular positions of the clamp body 1 along with the fixing seat 4, so that the float 3 applies buoyancy to various positions of the clamp body 1 through the supporting cable 6, ensuring that various positions of the clamp body 1 are fully supported by buoyancy and remain stably suspended underwater.
[0037] In some embodiments, a cable support sleeve 8 is sleeved on the connecting cables 5 between adjacent fixing seats 4 . The cable support sleeve 8 is arc-shaped and is located on the circumference of the clamp body 1 .
[0038] Both ends of the cable support sleeve 8 are attached to the corresponding fixing seat 4. The cable support sleeve 8 radially supports and constrains the flexible connecting cable 5 so that it is arranged along the clamp body 1, avoiding it from moving into the inner space of the clamp body 1 when being tightened, thereby preventing the connecting cable 5 from occupying the internal space of the clamp body 1 and causing obstruction to the installation of the catheter frame.
[0039] In some embodiments, the cable support sleeves 8 are connected to the corresponding floating bodies 3 above through connecting lines (not shown in the drawings), so that when the connecting cables 5 are cut, the floating bodies 3 that float up can pull the cable support sleeves 8 upwards through the connecting lines to make them disengage from the connecting cables 5. As the floating bodies 3 float to the water surface for recovery, the recovery rate of the components is improved and the equipment cost of the clamp installation is reduced.
[0040] In some embodiments, the cable support sleeve 8 is a rubber hose. The rubber hose has a certain shape and is relatively soft. When the opening 11 is opened, the rubber hose can be deformed along the clamp body 1 to keep the connection cable 5 arranged along the clamp body 1. In addition, while ensuring that the rubber hose radially constrains the connection cable 5, when the diver or ROV removes the floating body 3, the cable support sleeve 8 connected to the connection cable 5 can be cut off together, avoiding the cable support sleeve 8 from hindering the cutting of the connection cable 5.
[0041] In some embodiments, the end of the cable support sleeve 8 has a positioning plug 81, and the positioning plug 81 is inserted into the corresponding fixing hole and / or connecting hole. The cable support sleeve 8 is connected to the fixing seat 4 through the positioning plug 81, so that the fixing seat 4 vertically supports the cable support sleeve 8, thereby keeping the radial and vertical positions of the cable support sleeve 8 stable, ensuring that the connecting cable 5 is arranged close to the circumference of the surface of the clamp body 1, tightening the connecting seat 7, and preventing the loosening of the connecting cable 5 from causing the clamp body 1 to float up and down during the floating process.
[0042] In some embodiments, when the end of the connecting cable 5 extends toward the opening 11, it passes through the fixing ring 13 installed on the clamp body 1 and is fixedly connected to the limited end 9. The outer diameter of the limited end 9 is larger than the inner diameter of the fixing ring 13, so that the end of the connecting cable 5 cannot escape from the fixing ring 13 in a direction away from the opening 11, so that the clamp body 1 can keep the connection cable 5 constrained by the fixing ring 13.
[0043] After the connecting cable 5 is cut, if the connecting cable 5 is fixedly connected to the clamp body 1, the connecting cable 5 is restricted underwater with the clamp body 1 and floats with the water flow, which can easily cause divers or ROVs to be entangled by it, causing obstacles to underwater operations. After the connecting cable 5 is cut, the connecting cable 5 can not only be pulled out of the fixing seat 4 and the connecting seat 7, but also the fixing ring 13, completely separated from the clamp body 1, and avoid the obstruction of the connecting cable 5 to underwater operations. When the limiting end 9 adopts a component with strong buoyancy, it and the floating body 3 jointly support the clamp body 1 to make it suspended, and after the connecting cable 5 is cut, the limiting end 9 floats up, and the connecting cable 5 is pulled out from the fixing ring 13, and it is floated to the water surface with the limiting end 9, realizing the automatic recovery of the connecting cable 5.
[0044] In some embodiments, the connecting cable 5 is a rubber band rope, one end of which is connected to one side of the opening, and the other end is stretched when passing through each fixing seat 4 in sequence along the clamp body 1, and then connected to the other side of the opening. Since the connecting cable 5 is stretched, elastic force is generated. When the connecting cable is cut, its elastic force causes it to shorten quickly, so that the fixing seat 4 and the connecting seat 7 are quickly pulled out, and the connection between the floating body 3 and the clamp body 1 is effectively eliminated, so that the floating body 3 can float and be recovered faster, thereby improving the operation efficiency.
[0045] In some embodiments, multiple fixing seats 4 are evenly arranged in the circumferential direction so that the fixing seats 4 provide sufficient and uniform radial support to the connecting cable 5, thereby avoiding uneven distribution of the fixing seats 4 causing the connecting line between two fixing seats 4 to be too close to the center of the clamp body 1, preventing the connecting cable 5 from occupying the internal space of the clamp body 1 and hindering the entry of the catheter frame, thereby ensuring smooth installation of the clamp body 1.
[0046] In some embodiments, the number of fixing seats 4 and connecting seats 7 is the same, and each connecting seat 7 is aligned with the corresponding fixing seat 4, so that the float 3 can evenly apply the buoyancy to various positions of the clamp body 1 through the supporting cable 6, thereby ensuring the stability of the suspension of the clamp body 1.
[0047] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
[0048] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for which protection is requested in the utility model.
