Description

Technical Field

[0001] The present invention relates to the technical field of enclosing systems, and particularly to a thin-film enclosing system. Background Art

[0002] Liquefied natural gas (LNG) has become a key pillar in the energy field due to its clean and efficient characteristics. The cryogenic storage equipment for LNG relies on high-performance enclosing systems to prevent medium leakage and maintain heat insulation performance. Among them, as a core component, the thin-film enclosing system needs to balance heat insulation, sealing and structural reliability. However, there are still significant defects in the existing technologies, which limit its actual application effect.

[0003] For example, a Chinese invention patent with the publication number CN117048777B discloses a thin-film enclosing system, which realizes the mechanical connection of the primary and secondary heat insulation modules through components such as primary layer clamping plates, secondary layer clamping plates and connecting screws. However, in this solution, the connecting parts (such as screws and clamping plates) directly penetrate the heat insulation modules, and the thermal conductivity of such metal materials is much higher than that of the thermal insulation materials, resulting in heat conduction from the external environment to the inside of the cryogenic storage equipment through the connecting parts, forming a "cold bridge effect". The existence of the cold bridge not only greatly increases the cold loss of the equipment, reduces the heat insulation efficiency, but also significantly increases the energy consumption and operation cost. Moreover, it uses the method of matching screws with nuts for fixation, and there is a phenomenon of inconvenient disassembly and assembly.

[0004] Therefore, there is an urgent need for a new type of thin-film enclosing system that can completely block the heat conduction path of the cold bridge and is convenient for disassembly and assembly. Summary of the Invention

[0005] The purpose of the present invention is to provide a thin-film enclosing system, so as to solve or at least alleviate one or more of the above problems and other problems existing in the prior art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A thin-film enclosing system includes a shielding module and a heat insulation module. The shielding module includes a secondary shielding film layer and a primary shielding film layer. The primary shielding film layer is arranged above the secondary shielding film layer. A primary plywood is arranged between the secondary shielding film layer and the primary shielding film layer. An anchor plate is fixedly connected to the top of the primary plywood. The primary shielding film layer is welded to the anchor plate. A stud is fixedly installed at the top of the heat insulation module. The stud passes through the secondary shielding film layer and the primary plywood and is threadedly installed with a nut;

[0007] The lower end of the heat insulation module is connected to the inner wall of the ship through a disassembly and assembly mechanism, and the upper end of the heat insulation module is in a heat insulation and sealing state.

[0051] Please refer to Figures 1 to 10 , this embodiment provides a thin-film enclosure system, including: a shielding module and a heat insulation module. The shielding module includes a secondary shielding thin film layer 5 and a primary shielding thin film layer 6. The primary shielding thin film layer 6 is disposed above the secondary shielding thin film layer 5. A main plywood is provided between the secondary shielding thin film layer 5 and the primary shielding thin film layer 6. An anchor plate is fixedly connected to the top of the main plywood. The primary shielding thin film layer 6 is welded to the anchor plate. A stud is fixedly installed at the top of the heat insulation module. The stud passes through the secondary shielding thin film layer 5 and the main plywood and is threadedly installed with a nut;

[0052] The lower end of the heat insulation module is connected to the inner wall 1 of the ship through a disassembly and assembly mechanism 7, and the upper end of the heat insulation module is in a heat insulation and sealing state.

[0053] The primary shielding thin film layer 6 is connected to the main plywood by means of the anchor plate, and the secondary shielding thin film layer 5 is located below. The two cooperate to achieve the shielding function. The stud at the top of the heat insulation module passes through the secondary shielding thin film layer 5 and the main plywood and is fastened with a nut to determine the relative position of the heat insulation module and the shielding module. The primary shielding thin film layer 6 and the secondary shielding thin film layer 5 are independent of each other to ensure that deformation does not affect each other, improving the system's sealing performance and reliability. The lower end of the heat insulation module is connected to the inner wall 1 of the ship through the disassembly and assembly mechanism 7, which is convenient for installation and disassembly. The heat insulation and sealing design at the upper end of the heat insulation module cuts off the cold bridge phenomenon, reduces heat loss, and improves the heat insulation performance.

[0054] In this embodiment, the heat insulation module includes a lower plywood board 2, an enhanced polyurethane heat insulation layer 3, and an upper plywood board 4. The lower plywood board 2 is fixedly bonded to the bottom of the enhanced polyurethane heat insulation layer 3, and the upper plywood board 4 is fixedly bonded to the top of the enhanced polyurethane heat insulation layer 3. The stud is fixedly connected to the upper plywood board 4.

[0055] The lower plywood board 2 and the upper plywood board 4 are respectively firmly bonded to the bottom and the top of the enhanced polyurethane heat insulation layer 3, jointly forming a complete heat insulation structure body. The enhanced polyurethane heat insulation layer 3 undertakes the main heat insulation task, and the plywood board plays a role in protecting the heat insulation layer and enhancing the overall structural strength.

[0056] In this embodiment, the disassembly and assembly mechanism 7 includes a plug-in member and a clamping member;

[0057] The plug-in member includes a vertical rod 701. The vertical rod 701 is fixedly installed on the inner wall 1 of the ship body. One end of the vertical rod 701 away from the inner wall 1 of the ship body is fixedly connected with a connecting rod 7011, and one end of the connecting rod 7011 away from the vertical rod 701 is fixedly connected with an upper frustum-shaped block 7012;

[0058] A first through hole 201 is formed in the lower plywood board 2, and a lower installation groove 302 is formed in one end of the enhanced polyurethane heat insulation layer 3 close to the lower plywood board 2;

[0059] The clamping member is installed on the lower plywood board 2 through a connecting member, and the clamping member is located in the lower installation groove 302; The clamping member includes a first housing 703, a clamping block 7032, a movable rod 7033, and a third spring 7034. A sliding groove 70313 is formed in the outer wall of the lower end of the first housing 703, a guiding groove 70311 is formed in the inner wall of the lower end of the first housing 703, a cavity 70312 is formed in the first housing 703, one end of the cavity 70312 is communicated with the sliding groove 70313, the other end of the cavity 70312 is communicated with one end of the guiding groove 70311, the clamping block 7032 is slidably arranged in the guiding groove 70311, one end of the movable rod 7033 slidably penetrates through the sliding groove 70313 and the cavity 70312 and then extends into the guiding groove 70311 to be fixedly connected with one end of the clamping 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 clamping block 7032, the other end of the third spring 7034 abuts against one end of the cavity 70312, and a limiting block 7035 is fixedly connected to the end of the movable rod 7033 away from the clamping block 7032;

[0060] The upper frustum-shaped block 7012 extends into the lower installation groove 302 from the first through hole 201, and one end of the clamping block 7032 away from the movable rod 7033 can abut against the bottom of the upper frustum-shaped block 7012, thereby fixing the upper frustum-shaped block 7012 in the first housing 703.

[0061] During installation, push the heat insulation module towards the inner wall 1 of the ship's hull, so that the upper frustum-shaped 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 continuously moves towards the inner wall 1 of the ship's hull, the clamping block 7032 can be clamped at the bottom of the upper frustum-shaped block 7012, completing the locking of the clamping part and the plug-in part, thereby fixing the heat insulation module to the inner wall 1 of the ship's hull.

[0062] In this embodiment, a frustum-shaped block 7013 is slidably sleeved at one end of the connecting rod 7011 close to the vertical rod 701, and a guiding inclined surface is provided at one end of the clamping block 7032 away from the movable rod 7033.

[0063] During disassembly, press the first housing 703, so that the clamping block 7032 moves from the bottom of the upper frustum-shaped block 7012 to the side of the frustum-shaped block 7013 through the guiding inclined surface, and then move the first housing 703 in the direction away from the inner wall 1 of the ship's hull. The frustum-shaped block 7013 moves due to the extrusion of the clamping block 7032. When the frustum-shaped block 7013 contacts the upper frustum-shaped block 7012, the clamping block 7032 moves along the side of the frustum-shaped block 7013 to the side of the upper frustum-shaped block 7012, thereby realizing the disassembly of the heat insulation module from the inner wall 1 of the ship's hull. The frustum-shaped block 7013 plays an auxiliary disassembly role in this process, changing the position of the clamping block 7032 by its special shape to achieve rapid disassembly.

[0064] In this embodiment, the connecting part includes a first flange 702. The first flange 702 is fixedly installed on the lower plywood 2. A guiding rod 7021 is fixedly connected to the top of the first flange 702. A second spring 7022 is sleeved on the guiding rod 7021. An annular plate 7031 is fixedly connected to the outer wall of the bottom of the first housing 703. The upper end of the guiding rod 7021 slidably penetrates through the annular plate 7031 and is fixedly connected with a stop block 7023. The bottom of the second spring 7022 presses on the top of the first flange 702, and the top of the second spring 7022 abuts against the bottom of the annular plate 7031. The first flange 702 is fixed on the lower plywood 2 as the basic connecting component. The guiding rod 7021 and the stop block 7023 cooperate with each other to limit the moving range of the first housing 703. The second spring 7022 is arranged between the first flange 702 and the annular plate 7031, playing a buffering and resetting role. When the first housing 703 is subjected to an external force, it can slide along the guiding rod 7021, and the second spring 7022 compresses or extends according to the force condition, ensuring the stability and flexibility of the connection structure.

[0065] In this embodiment, a first spring 7014 is sleeved on the connecting rod 7011. The top of the first spring 7014 abuts against the bottom of the upper frustum-shaped block 7012. An assembly groove 70131 is provided at the top of the frustum-shaped block 7013, and the bottom of the first spring 7014 presses on the bottom of the assembly groove 70131.

[0066] Through the provided first spring 7014, the upper frustum-shaped block 7012 can be separated from the inverted frustum-shaped block 7013 in the natural state, preventing the upper frustum-shaped block 7012 from contacting the inverted frustum-shaped block 7013 during installation, and the latch 7032 cannot be latched at the bottom of the upper frustum-shaped block 7012.

[0067] In this embodiment, an operating assembly 8 is further included. The operating assembly 8 includes an operating rod 803. A second through hole 401 is formed in the top of the upper plywood 4. A communication groove 303 communicating with the lower installation groove 302 is formed in the top of the enhanced polyurethane heat insulation layer 3. The lower end of the operating rod 803 passes through the second through hole 401 and extends into the communication groove 303. A polyurethane heat insulation sleeve 804 is fixedly bonded to the outer wall of the lower end of the operating rod 803. The polyurethane heat insulation sleeve 804 is in sliding and sealing contact with the communication groove 303. By pressing down the operating rod 803, a pressure can be applied to the first housing 703 towards the inner wall 1 of the ship's body.

[0068] The operating rod 803 passes through the second through hole 401 of the upper plywood 4 and the communication groove 303 of the enhanced polyurethane heat insulation layer 3. The polyurethane heat insulation sleeve 804 at the lower end is in sliding and sealing contact with the communication 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 down, the force is transmitted to the first housing 703, realizing the application of a pressure to the first housing 703 towards the inner wall 1 of the ship's body, facilitating the operation during the installation and disassembly processes.

[0069] In this embodiment, when the latch 7032 limits the upper frustum-shaped block 7012, the polyurethane heat insulation sleeve 804 is not in contact with the first housing 703.

[0070] When the latch 7032 limits the upper frustum-shaped block 7012, the polyurethane heat insulation sleeve 804 is not in contact with the first housing 703. Such a design is to avoid interfering with the fixed state of the latching member by the operating rod 803 and the polyurethane heat insulation sleeve 804 during normal use, ensuring the stability of the connection structure. Only when operation is required, pressing the operating rod 803 will cause relevant components to act. Moreover, in this state, the polyurethane heat insulation sleeve 804 is not in contact with the first housing 703, further reducing heat transfer.

[0071] In this embodiment, the operating component 8 further includes a second flange 802. The second flange 802 is fixedly installed at the bottom of the upper plywood 4. A second housing 801 is fixedly connected to the bottom of the second flange 802. An upper installation groove 301 is formed at the top of the enhanced polyurethane heat insulation layer 3. The second housing 801 is located inside the upper installation groove 301. The operating rod 803 slidably penetrates through the second housing 801. A circular plate 805 is fixedly connected to the operating rod 803. The circular plate 805 is slidably arranged inside the second housing 801. A fourth spring 806 is sleeved on the operating rod 803. The top of the fourth spring 806 abuts against the bottom of the circular plate 805. The bottom of the fourth spring 806 presses against the inner bottom of the second housing 801.

[0072] When the operating rod 803 is pressed, the circular plate 805 compresses the fourth spring 806. When the external force is withdrawn, the fourth spring 806 pushes the circular plate 805 and the operating rod 803 to reset, facilitating the next operation. Through this setting, it is avoided that the operating rod 803 contacts the first housing 703 when the operating rod 803 is not operated.

[0073] In this embodiment, when in the natural state, the top of the operating rod 803 is located inside the second through hole 401.

[0074] In the natural state, the top of the operating rod 803 is located inside the second through hole 401, ensuring that the operating rod 803 will not protrude randomly due to external force and will not affect the installation of the shielding module.

[0075] Working principle:

[0076] During installation, the heat insulation module is pushed towards the inner wall 1 of the ship's hull, so that the upper frustum-shaped 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 towards the inner wall 1 of the ship's hull, the clamping block 7032 can be clamped at the bottom of the upper frustum-shaped block 7012, completing the locking of the clamping part and the plug-in part;

[0077] During disassembly, the operating rod 803 is pressed downwards, and the polyurethane heat insulation sleeve 804 pushes the first housing 703 to move towards the inner wall 1 of the ship's hull.

[0078] The clamping block 7032 is made to move from the bottom of the upper frustum-shaped block 7012 to the side surface of the inverted frustum-shaped block 7013 through the guiding inclined surface. At this time, the operating lever 803 is released. The operating lever 803 is reset upward under the elastic force of the fourth spring 806, while the first housing 703 moves away from the inner wall 1 of the ship under the elastic force of the second spring 7022, thereby driving the clamping block 7032 to move away from the inner wall 1 of the ship. The inverted frustum-shaped block 7013 moves away from the inner wall 1 of the ship along with the first housing 703 under the extrusion of the clamping block 7032. When the inverted frustum-shaped block 7013 contacts the upper frustum-shaped block 7012, the clamping block 7032 moves along the side surface of the inverted frustum-shaped block 7013 to the side surface of the upper frustum-shaped block 7012, and thus the disassembly is completed.

[0079] Parts not involved in the present invention are the same as or can be implemented using the prior art. Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
