Description

Technical Field

[0001] The present invention relates to the technical field of offshore renewable energy development platforms, in particular to a temperature difference energy power generation platform capable of self-storage, transportation, and disassembly of pipelines, and a method for using the platform. Background Art

[0002] Ocean temperature difference energy refers to the heat energy stored between surface seawater (temperature 25℃~28℃) and deep cold seawater (temperature 7℃~4℃, seawater at a depth of 800m~1000m). When the temperature difference is greater than 18℃, it has the value of being developed as energy.

[0003] The main heat cycles of temperature difference energy are: Rankine cycle, Kalina cycle, Uehara cycle and Guohai cycle. No matter which cycle is used, deep cold seawater must be used as a cold source and surface warm seawater as a heat source. Therefore, the temperature difference energy power generation system must include: cold seawater pipes for extracting cold seawater at a depth of about 800 meters or more; warm seawater pipes for extracting surface warm seawater; and drainage pipes that discharge the water after heat exchange back to a depth of more than 30 meters underwater in order not to affect the marine ecology.

[0004] Since thermoelectric power generation requires more pipeline systems, the installation and deployment on the floating thermoelectric power generation platform requires the assistance of engineering vessels, which is time-consuming, labor-intensive and uneconomical. Before the typhoon arrives, a long time must be reserved for ship-assisted pipeline dismantling, which has poor environmental adaptability and certain safety hazards. Summary of the invention

While meeting good wave resistance, it can store, transport, install and disassemble water intake and drainage pipe systems by itself, saving installation time and economic costs. Before the arrival of a typhoon, the platform can quickly disassemble and transport the pipes through its own lifting, tensioning and transportation systems, providing sufficient time for the platform to migrate and avoid the typhoon, thereby greatly improving the safety of the platform.

[0031] Installation phase:

[0032] The first section of pipes to be installed is transported along the transport track to the overlapping section of the first transport track and the second transport track through the lifting transport platform and the transport trolley.

[0033] The second transport trolley top plate of the second transport trolley descends, so that the pipes to be installed are loaded onto the first transport top plate of the first transport trolley which is in place in advance.

[0080] The sliding track 4-5 is laid on the platform body 1, and the sliding track 4-5 points to the moon pool 1-4.

[0081] One end of the support frame 4-1 falls on the sliding track 4-5, and the other end is connected to the buffer pad 4-2.

[0082] One end of the hydraulic rod 4-3 is hinged to the platform body 1, and the other end is hinged to the support frame 4-1.

[0083] The side of the buffer pad 4 - 2 facing the pipe fitting 6 to be installed is concavely arranged to accommodate the pipe fitting 6 to be installed.

[0084] A plurality of tensioners 5 are installed at the moon pool 1-4, each tensioner 5 is arranged in pairs, including two symmetrically arranged telescopic platforms 5-1, and the opposite side of the telescopic platform 5-1 is concave to form a semicircular opening 5-3, an elastic pad 5-4 is arranged at the semicircular opening 5-3, and a fastener 5-2 is arranged between the elastic pad 5-4 and the semicircular opening 5-3.

[0085] The fasteners 5-2 are arranged in a circular array.

[0086] The platform body 1 includes an upper floating body 1-1, a lower floating body 1-2, and a column 1-3 connecting the upper floating body 1-1 and the lower floating body 1-2. The lower floating body 1-2 is formed by a combination of several pontoons, which are corresponding to the pontoons under the moon pool 1-4 and are used to accommodate the pipes 6 to be installed and extend underwater.

[0087] The method for using the temperature difference energy power generation platform capable of self-storage, transportation, and disassembly of pipelines in this embodiment includes the following steps:

[0088] Installation phase:

[0089] The first section of the pipe 6 to be installed is transported along the transport track to the overlap section of the first transport track 3-2 and the second transport track 3-4 through the lifting transport platform 3-5 and the transport trolley.

[0090] The second transport vehicle top plate 3-3-2 of the second transport vehicle descends, so that the pipe fittings 6 to be installed are carried onto the first transport top plate of the first transport vehicle in place in advance. The first transport vehicle transports the pipe fittings 6 to be installed along the first transport track 3-2 to the anti-collision system 4, and the pipe fittings 6 to be installed fall on the elastic pad 5-4 of the anti-collision system 4.

[0091] The equipment platform 2-2 of the lifting system 2 moves along the lifting track 2-5 to the anti-collision system 4, and the hook of the lifting device 2-3 lifts the end of the pipe 6 to be installed close to the elastic pad 5-4; during the lifting process, the hydraulic rod 4-3 gradually extends to lift the support frame 4-1 away from the platform body 1, and the end of the support frame 4-1 that falls on the sliding track 4-5 moves along the sliding track 4-5; the pipe 6 to be installed always falls on the elastic pad 5-4 during the lifting process.

[0092] After the pipe 6 to be installed is completely hoisted, the equipment platform 2-2 moves in the opposite direction along the lifting track 2-5, driving the pipe 6 to be installed to move above the moon pool 1-4, corresponding to one of the tensioners 5.

[0093] The two telescopic platforms 5-1 of the tensioner 5 are in a separated state. The lifting system lowers the pipe fitting 6 to be installed, and the pipe fitting 6 to be installed falls between the two telescopic platforms 5-1. The hydraulic power source pushes the two telescopic platforms 5-1 to move relative to each other, clamping the pipe fitting 6 to be installed.

[0094] The fastener 5-2 is driven by a hydraulic power source to push toward the pipe 6 to be installed, thereby fastening the pipe 6 to be installed.

[0095] When installing the second pipe 6 to be installed, repeat the above steps. When the second pipe 6 to be installed is transported to the top of the first pipe 6 to be installed, the two pipes are connected by flanges, and the tensioner 5 is loosened. After the two connected pipes are lowered to the expected length, the tensioner 5 is used to lock them again.

[0096] Demolition phase:

[0097] First, lift the installed pipe fittings, remove the flange between the two pipe fittings, lift the upper pipe fittings to the anti-collision system 4, drop it on the anti-collision system 4, and then use the first transport trolley to transport the pipe fittings to the docking position of the second transport trolley, and then use the second transport trolley to transport the pipe fittings to the lifting and transport platform 3-5 to complete the disassembly and recycling of the pipe fittings.

[0098] The specific structure and working principle of the present invention are as follows:

[0099] like Figure 1 As shown, the overall structure includes a platform body 1, a lifting system 2, a pipeline transportation system 3, an anti-collision system 4 and a tensioner 5.

[0100] like Figure 1 As shown, the platform body 1 includes an upper buoy 1-1, a lower buoy 1-2 and four columns 1-3 connecting the upper and lower buoys. The lower buoy 1-2 is composed of four octagonal buoys 1-2a, one annular buoy 1-2b and four transition buoys 1-2c. Among them, the annular buoy 1-2b located in the middle is set through the middle to accommodate the lowering of pipes. Figure 1 In the coordinate orientation in the middle, the platform body 1 is symmetrical about the X-axis and the Y-axis, and a rectangular moon pool 1-4 is opened at the center of the upper floating body. The platform structure adopts a semi-submersible configuration, which is conducive to improving its wave resistance and reducing the movement of the platform in wind and waves.

[0101] like Figure 1 and Figure 2As shown, the lifting system 2 is erected above the moon pool 1-4, and includes a truss structure 2-1, an equipment platform 2-2, a lifting device 2-3, four sliding wheels 2-4 symmetrically distributed on the left and right, and two lifting tracks 2-5 symmetrically arranged on both sides of the moon pool 1-4. The lifting device 2-3 is arranged on the equipment platform 2-2, and the vertical distance between the equipment platform 2-2 and the floating body 1-1 on the platform is not less than 2 meters, which helps to avoid structural interference and collision when lifting pipes. The sliding wheel 2-3 moves along the track 2-4, which is convenient for lifting and installing different pipes.

[0102] like Figure 1 and Figure 2 As shown, the pipeline transport system 3 includes a plurality of first transport trolleys 3-1 and first transport rails 3-2 adapted thereto, a plurality of second transport trolleys 3-3 and second transport rails 3-4 adapted thereto, and a lifting transport platform 3-5.

[0103] like Figures 3 to 7 As shown, the first transport trolley 3-1 comprises a first transport trolley bottom plate 3-1-1, a first transport trolley top plate 3-1-2, a first connecting shaft 3-1-3 and four first spherical rollers 3-1-4. The first connecting shaft 3-1-3 is located in the middle of the first transport trolley bottom plate 3-1-1 and the first transport trolley top plate 3-1-2, so that the first transport trolley bottom plate 3-1-1 and the first transport trolley top plate 3-1-2 can rotate and lift relative to each other around the vertical center axis. The first transport trolley bottom plate 3-1-1 is made of rubber. The spacing between the first spherical rollers 3-1-4 is consistent with the width of the first transport track 3-2, and the minimum distance between adjacent rollers 3-1-4 is a.

[0104] The second transport trolley 3-3 comprises a second transport trolley bottom plate 3-3-1, a second transport trolley top plate 3-3-2, a second connecting shaft 3-3-3 and four second spherical rollers 3-3-4. The second connecting shaft 3-3-3 is located in the middle of the second transport trolley bottom plate 3-3-1 and the second transport trolley top plate 3-3-2, so that the second transport trolley bottom plate 3-3-1 and the second transport trolley top plate 3-3-2 can rotate and lift relative to each other around the vertical center axis. The second transport trolley bottom plate 3-3-1 is made of rubber. The spacing between the second spherical rollers 3-3-4 is consistent with the width of the second transport track 3-4 and is smaller than the width of the first transport track 3-2. The width of the second transport trolley bottom plate 3-3-1 is b, and b<a, to avoid interference between the first transport trolley and the second transport trolley.

[0105] The length of the overlapped portion of the second transport track 3-4 and the first transport track 3-2 is greater than the length of the single module pipeline, which is convenient for the transport trolley to cooperate with the transport pipeline. The lifting transport platform 3-5 is located on the upper floating body 1-1, and the second transport track 3-4 is extended to the lifting transport platform 3-5 and disconnected at the end of the lifting transport platform 3-5, so that the part of the track fixed on the lifting transport platform 3-5 can be lifted and lowered together with the lifting transport platform 3-5, which is used to transport the pipeline inside and on the upper floating body 1-1.

[0106] like Fig. 9 As shown, the anti-collision system 4 includes a support frame 4-1, a buffer pad 4-2, two hydraulic rods 4-3 symmetrically distributed on the left and right, two rollers 4-4 symmetrically distributed on the left and right, and a sliding track 4-5 adapted to the rollers. One end of the support frame 4-1 is connected to the semicircular groove-shaped buffer pad 4-2, and the other end is connected to the roller 4-4 and can slide along the sliding track 4-5. The hydraulic rod 4-3 is respectively hinged to the upper floating body 1-1 and the support frame 4-1, and the length of the hydraulic rod 4-3 is changed by hydraulic pressure.

[0107] like Fig.10 , 11 As shown, the tensioner 5 includes a drain pipe tensioner 5-A for fastening the pipe 6 to be installed, a cold water pipe tensioner 5-B for fastening the cold water pipe 7, and a warm water pipe tensioner 5-C for fastening the warm water pipe 8. Each tensioner includes two telescopic platforms 5-1 and no less than 3 sets of fasteners 5-2, preferably 4 to 8 sets. One end of the telescopic platform 5-1 can be embedded in the inner wall of the platform moon pool 1-4, and a semicircular opening 5-3 is provided at the midpoint of the other end. The telescopic platform 5-1 can be driven by hydraulic pressure and can be telescopic along the Y-axis direction. When the left and right telescopic platforms 5-1 are extended, a circular opening is formed at the contact end. The fasteners 5-2 are evenly arranged on the side of the circular opening and can be telescopically adjusted by hydraulic pressure. The contact end of the fastener 5-2 and the pipe 6, 7 or 8 is an elastic pad 5-4. The pipe 6 to be installed can be a drain pipe, a cold water pipe 7 and a warm water pipe 8.

[0108] like Figure 1 As shown, the pipe fitting 6 to be installed is connected in sections, and the two ends of each section are provided with interfaces for mounting flanges, which are connected by flanges. The pipe fitting 6 to be installed is stored in the floating body 1-1 on the platform before installation or after disassembly.

[0109] The steps for pipe installation are as follows, taking the drainage pipe as an example:

[0110] 1. Use the lifting and transporting platform 3-5 and two second transporting trolleys 3-3 to transport the first section of the drainage pipe to the overlapping part of the second transporting track 3-4 and the first transporting track 3-2;

[0111] 2. The bottom plate 3-3-1 of the second transport trolley 3-3 is lowered, so that the drainage pipe is carried on the pre-positioned first transport trolley 3-1, and then transported to the anti-collision system 4 through the first transport track 3-2, and one end of the drainage pipe is placed above the semicircular groove-shaped buffer pad 4-2;

[0112] 3. The lifting system 2 moves close to the drain pipe through the track 2-5, and lifts the drain pipe by placing one end above the semicircular groove-shaped buffer pad 4-2. At the same time, the hydraulic rod 4-3 is extended, and one end of the support frame 4-1 slides along the sliding track 4-5, so that the other end of the support frame 4-1 is lifted in coordination with the lifting process of the drain pipe. During the lifting process, the drain pipe is always in contact with the semicircular groove-shaped buffer pad 4-2 to prevent the pipe from shaking and colliding with other structures and equipment;

[0113] 4. After the drain pipe is lifted vertically, the lifting system 2 slowly moves to the top of the drain pipe tensioner 5-A through the track 2-5;

[0114] 5. The two telescopic platforms 5-1 of the tensioner 5-A are in a separated state. Place the drain pipe downward between the two telescopic platforms 5-1, and extend and close the two telescopic platforms 5-1 through hydraulic drive. At this time, the drain pipe is located in the circular opening formed by the contact ends of the telescopic platforms 5-1;

[0115] 6. Adjust the fastener 5-2 by hydraulic pressure so that the tensioner tightens the drain pipe and loosens the connection between the lifting system 2 and the drain pipe;

[0116] 7. Repeat steps 1 to 4 above to move the next section of the drainage pipe to the top of the first section of the drainage pipe and connect the two sections of the drainage pipe through the flange. Loosen the fastener 5-2 by hydraulic pressure, and lower the two connected sections of the drainage pipe to the appropriate position by the lifting system 2. Then adjust the fastener 5-2 by hydraulic pressure to tighten the tensioner on the second section of the drainage pipe and loosen the connection between the lifting system 2 and the second section of the drainage pipe.

[0117] 8. Repeat the above step 7 to complete the installation of the entire drain pipe 6;

[0118] 9. Follow similar steps to install the drain pipe 6, cold water pipe 7 and warm water pipe 8 in sequence.

[0119] The steps for disassembling the piping system of the temperature difference energy power generation platform by itself are the reverse steps of the installation steps.

The anti-collision system (4) comprises a support frame (4-1), a buffer pad (4-2), two hydraulic rods (4-3) symmetrically distributed on the left and right, two rollers (4-4) symmetrically distributed on the left and right, and a sliding track (4-5) adapted to the rollers. Each tensioner comprises two telescopic platforms (5-1) and at least three sets of fasteners (5-2). The contact end between the fastener (5-2) and the pipe where it is located is an elastic pad (5-4). The steps include: Installation phase: The first section of the pipe fitting (6) to be installed is transported along the transport track to the overlapping section of the first transport track (3-2) and the second transport track (3-4) by means of the lifting transport platform (3-5) and the transport trolley. The second transport vehicle top plate (3-3-2) of the second transport vehicle descends, so that the pipe fitting (6) to be installed is loaded onto the first transport top plate of the first transport vehicle which is in place in advance. The first transport vehicle transports the pipe fitting (6) to be installed along the first transport track (3-2) to the anti-collision system (4), and the pipe fitting (6) to be installed falls on the elastic pad (5-4) of the anti-collision system (4). The equipment platform (2-2) of the lifting system (2) moves along the lifting track (2-5) to the vicinity of the anti-collision system (4), and the hook of the lifting device (2-3) lifts the end of the pipe fitting (6) to be installed close to the elastic pad (5-4); during the lifting process, the hydraulic rod (4-3) gradually extends to lift the support frame (4-1) away from the platform body (1), and the end of the support frame (4-1) that falls on the sliding track (4-5) moves along the sliding track (4-5); the pipe fitting (6) to be installed always falls on the elastic pad (5-4) during the lifting process. After the pipe (6) to be installed is completely hoisted, the equipment platform (2-2) moves in the opposite direction along the lifting track (2-5), driving the pipe (6) to be installed to move to the top of the moon pool (1-4), corresponding to one of the tensioners (5). The two telescopic platforms (5-1) of the tensioner (5) are in a separated state, the lifting system lowers the pipe fitting (6) to be installed, and the pipe fitting (6) to be installed falls between the two telescopic platforms (5-1), and the hydraulic power source drives the two telescopic platforms (5-1) to move relative to each other, thereby clamping the pipe fitting (6) to be installed. The fastener (5-2) is driven by a hydraulic power source to push toward the pipe fitting (6) to be installed, thereby fastening the pipe fitting (6) to be installed. When installing the second pipe fitting (6) to be installed, repeat the above steps. When the second pipe fitting (6) to be installed is transported to the top of the first pipe fitting (6) to be installed, the two pipe fittings are connected by flanges, and the tensioner (5) is loosened. After the two connected pipe fittings are lowered to the expected length, the tensioner (5) is used to lock them again. Demolition phase: First, the installed pipe fittings are lifted, the flanges between the two pipe fittings are removed, the upper pipe fittings are lifted to the anti-collision system (4), and dropped onto the anti-collision system (4), and then the first transport trolley transports the pipe fittings to the docking position of the second transport trolley, and the second transport trolley transports the pipe fittings to the lifting transport platform (3-5), thereby completing the disassembly and recycling of the pipe fittings.
