Description

Technical Field

[0001] The invention relates to the technical field of enclosure systems, in particular to a film enclosure system. Background Art

[0002] Liquefied natural gas (LNG) has become a key pillar in the energy sector due to its clean and efficient characteristics. LNG cryogenic storage equipment needs to rely on high-performance containment systems to prevent medium leakage and maintain thermal insulation performance. Among them, the film containment system, as a core component, must take into account thermal insulation, sealing and structural reliability. However, there are still significant defects in the existing technology, which limits its practical application effect.

[0003] For example, the Chinese invention patent with announcement number CN117048777B discloses a film-type enclosure system, which realizes the mechanical connection of the primary and secondary insulation modules through components such as the primary layer pallet, the secondary layer pallet, and the connecting screws. However, in this scheme, the connectors (such as screws and pallets) directly penetrate the insulation module, and the thermal conductivity of such metal materials is much higher than that of the insulation material, causing heat to be transferred from the external environment to the interior of the low-temperature storage device through the connector, forming a "cold bridge effect". The existence of cold bridges not only greatly increases the cooling loss of the equipment and reduces the insulation efficiency, but also significantly increases energy consumption and operating costs. Moreover, it is fixed by screws and nuts, which makes it inconvenient to disassemble and assemble.

[0004] Therefore, there is an urgent need for a new type of film enclosure system that can completely block the heat conduction path of the cold bridge and is easy to disassemble and assemble. Summary of the invention

The main shielding film layer 6 and the secondary shielding film layer 5 are independent of each other to ensure that deformation does not affect each other, thereby improving the sealing and reliability of the system. The lower end of the insulation module is connected to the inner wall 1 of the hull through a disassembly mechanism 7, which is convenient for installation and disassembly. The insulation sealing design at the top of the insulation module cuts off the cold bridge phenomenon, reduces heat loss, and improves insulation performance. In this embodiment, the insulation module includes a lower plywood 2, a reinforced polyurethane insulation layer 3 and an upper plywood 4. The lower plywood 2 is fixedly bonded to the bottom of the reinforced polyurethane insulation layer 3, the upper plywood 4 is fixedly bonded to the top of the reinforced polyurethane insulation layer 3, and the studs are fixedly connected to the upper plywood 4. The lower plywood 2 and the upper plywood 4 are firmly bonded to the bottom and top of the enhanced polyurethane insulation layer 3, respectively, and together constitute a complete insulation structure. The enhanced polyurethane insulation layer 3 undertakes the main insulation task, and the plywood plays a role in protecting the insulation layer and enhancing the overall structural strength. In this embodiment, the disassembly and assembly mechanism 7 includes a plug-in connector and a clamping connector; The plug-in component includes a vertical rod 701, which is fixedly mounted on the inner wall 1 of the hull body. One end of the vertical rod 701 away from the inner wall 1 of the hull body is fixedly connected to a connecting rod 7011, and one end of the connecting rod 7011 away from the vertical rod 701 is fixedly connected to an upper truncated cone block 7012. A first through hole 201 is formed on the lower plywood 2, and a lower mounting groove 302 is formed on one end of the enhanced polyurethane heat insulation layer 3 close to the lower plywood 2; The clamping member is installed on the lower plywood 2 through a connecting member, and the clamping member is located in the lower mounting groove 302; the clamping member includes a first shell 703, a clamping block 7032, a movable rod 7033 and a third spring 7034, a sliding groove 70313 is provided on the lower outer wall of the first shell 703, a guide groove 70311 is provided on the lower inner wall of the first shell 703, an inner cavity 70312 is provided on the first shell 703, one end of the inner cavity 70312 is connected to the sliding groove 70313, and the other end of the inner cavity 70312 is connected to one end of the guide groove 70311 The blocks 7032 are slidably arranged in the guide groove 70311, one end of the movable rod 7033 slides through the slide groove 70313 and the inner cavity 70312, and then extends into the guide groove 70311 and is fixedly connected with one end of the block 7032, the third spring 7034 is sleeved on the movable rod 7033, one end of the third spring 7034 abuts against one end of the block 7032, and the other end of the third spring 7034 abuts against one end of the inner cavity 70312, and one end of the movable rod 7033 away from the block 7032 is fixedly connected with the limiting block 7035; The upper truncated cone block 7012 extends from the first through hole 201 into the lower mounting groove 302 , and one end of the clamping block 7032 away from the movable rod 7033 can abut against the bottom of the upper truncated cone block 7012 , thereby fixing the upper truncated cone block 7012 in the first shell 703 . During installation, the heat insulation module is pushed to move toward the inner wall 1 of the hull, so that the upper truncated cone block 7012 passes through the first through hole 201 of the lower plywood 2 and enters the lower installation groove 302 of the enhanced polyurethane heat insulation layer 3. As the heat insulation module continues to move toward the inner wall 1 of the hull, the clamping block 7032 can be clamped at the bottom of the upper truncated cone block 7012, completing the locking of the clamping piece and the plug-in piece, thereby fixing the heat insulation module to the inner wall 1 of the hull.

[0025] In this embodiment, an inverted truncated cone block 7013 is slidably sleeved on one end of the connecting rod 7011 close to the vertical rod 701 , and a guiding inclined surface is provided on one end of the clamping block 7032 away from the movable rod 7033 . During disassembly, the first shell 703 is pressed so that the clamping block 7032 moves from the bottom of the upper truncated cone block 7012 to the side of the inverted truncated cone block 7013 through the guiding slope, and then the first shell 703 is moved away from the inner wall 1 of the hull, and the inverted truncated cone block 7013 moves due to the squeezing of the clamping block 7032. After the inverted truncated cone block 7013 contacts the upper truncated cone block 7012, the clamping block 7032 moves along the side of the inverted truncated cone block 7013 to the side of the upper truncated cone block 7012, thereby realizing the disassembly of the heat insulation module from the inner wall 1 of the hull. The inverted truncated cone block 7013 plays a role in assisting disassembly in this process, and uses its special shape to change the position of the clamping block 7032 to realize rapid disassembly. In this embodiment, the connecting member includes a first flange 702, which is fixedly mounted on the lower plywood 2, a guide rod 7021 is fixedly connected to the top of the first flange 702, a second spring 7022 is sleeved on the guide rod 7021, an annular plate 7031 is fixedly connected to the bottom outer wall of the first shell 703, the upper end of the guide rod 7021 slides through the annular plate 7031 and is fixedly connected to a stopper 7023, the bottom of the second spring 7022 is pressed on the top of the first flange 702, and the top of the second spring 7022 is against the bottom of the annular plate 7031. The first flange 702 is fixed on the lower plywood 2 as a basic component of the connection. The guide rod 7021 and the stopper 7023 cooperate with each other to limit the moving range of the first shell 703. The second spring 7022 is arranged between the first flange 702 and the annular plate 7031 to play a role of buffering and resetting. When the first shell 703 is subjected to an external force, it can slide along the guide rod 7021, and the second spring 7022 is compressed or stretched according to the force conditions to ensure the stability and flexibility of the connection structure. In this embodiment, a first spring 7014 is sleeved on the connecting rod 7011, and the top of the first spring 7014 is against the bottom of the upper truncated cone block 7012. A mounting groove 70131 is provided on the top of the inverted truncated cone block 7013, and the bottom of the first spring 7014 is pressed against the bottom of the mounting groove 70131. The first spring 7014 can be set to separate the upper truncated cone block 7012 from the inverted truncated cone block 7013 in a natural state, so as to avoid the upper truncated cone block 7012 and the inverted truncated cone block 7013 contacting each other during installation, and the blocking block 7032 cannot be stuck at the bottom of the upper truncated cone block 7012. In this embodiment, an operating component 8 is also included, which includes an operating rod 803. A second through hole 401 is opened on the top of the upper plywood 4, and a connecting groove 303 connected with the lower installation groove 302 is opened on the top of the enhanced polyurethane insulation layer 3. The lower end of the operating rod 803 passes through the second through hole 401 and extends into the connecting groove 303. A polyurethane insulation sleeve 804 is fixedly bonded to the outer wall of the lower end of the operating rod 803. The polyurethane insulation sleeve 804 is in sliding and sealing contact with the connecting groove 303. By pressing the operating rod 803 downward, pressure can be applied to the first shell 703 close to the inner wall 1 of the hull. The operating rod 803 passes through the second through hole 401 of the upper plywood 4 and the connecting groove 303 of the enhanced polyurethane heat insulation layer 3, and the polyurethane heat insulation sleeve 804 at the lower end is in sliding and sealing contact with the connecting groove 303, which not only ensures the heat insulation effect, but also enables the operating rod 803 to move flexibly. When the operating rod 803 is pressed downward, the force is transmitted to the first shell 703, so that the first shell 703 is pressed close to the inner wall 1 of the hull, which is convenient for operation during installation and removal. In this embodiment, when the blocking block 7032 is in the state of limiting the upper frustoconical block 7012 , the polyurethane heat insulating sleeve 804 has no contact with the first shell 703 . When the clamping block 7032 limits the upper truncated cone block 7012, the polyurethane heat-insulating sleeve 804 does not contact the first shell 703. This design is to avoid interference of the operating rod 803 and the polyurethane heat-insulating sleeve 804 with the fixed state of the clamping member during normal use, to ensure the stability of the connection structure, and only when operation is required, the relevant parts will be moved by pressing the operating rod 803, and in this state, the polyurethane heat-insulating sleeve 804 does not contact the first shell 703, further reducing heat transfer. In this embodiment, the operating component 8 also includes a second flange 802, which is fixedly installed on the bottom of the upper plywood 4. The bottom of the second flange 802 is fixedly connected to the second shell 801. The top of the enhanced polyurethane insulation layer 3 is provided with an upper mounting groove 301. The second shell 801 is located inside the upper mounting groove 301. The operating rod 803 slides through the second shell 801. The operating rod 803 is fixedly connected to a circular plate 805, which is slidably arranged inside the second shell 801. The operating rod 803 is sleeved with a fourth spring 806, the top of the fourth spring 806 is against the bottom of the circular plate 805, and the bottom of the fourth spring 806 is pressed against the inner bottom of the second shell 801. When the operating rod 803 is pressed, the circular plate 805 compresses the fourth spring 806. When the external force is removed, the fourth spring 806 pushes the circular plate 805 and the operating rod 803 to reset, facilitating the next operation. This arrangement prevents the operating rod 803 from contacting the first shell 703 when not in operation.

[0026] In this embodiment, in the natural state, the top of the operating rod 803 is located inside the second through hole 401 . In a natural state, the top of the operating rod 803 is located in the second through hole 401, ensuring that the operating rod 803 will not be extended randomly due to external force, and will not affect the installation of the shielding module. Working principle: During installation, the heat insulation module is pushed toward the inner wall 1 of the hull, so that the upper truncated cone block 7012 passes through the first through hole 201 of the lower plywood 2 and enters the lower installation groove 302 of the enhanced polyurethane heat insulation layer 3. As the heat insulation module continues to move toward the inner wall 1 of the hull, the clamping block 7032 can be clamped at the bottom of the upper truncated cone block 7012, completing the locking of the clamping piece and the plug-in piece; During disassembly, the operating rod 803 is pressed downward, and the polyurethane heat insulation sleeve 804 pushes the first shell 703 to move toward the inner wall 1 of the hull.

[0027] The block 7032 is moved from the bottom of the upper truncated cone block 7012 to the side of the inverted truncated cone block 7013 through the guiding inclined surface. At this time, the operating rod 803 is released, and the operating rod 803 is reset upward under the elastic force of the fourth spring 806, and the first shell 703 moves in the direction away from the inner wall 1 of the hull body under the elastic force of the second spring 7022, thereby driving the block 7032 to move in the direction away from the inner wall 1 of the hull body. The inverted truncated cone block 7013 moves in the direction away from the inner wall 1 of the hull body along with the first shell 703 under the squeezing of the block 7032. When the inverted truncated cone block 7013 contacts the upper truncated cone block 7012, the block 7032 moves along the side of the inverted truncated cone block 7013 to the side of the upper truncated cone block 7012, and the disassembly is completed.
