Description

Technical Field

[0001] The present invention relates to the technical field of fireproof bulkhead panels, in particular to an A60-class bulkhead fireproof partition wall panel structure. Background Art

[0002] As domestic ships transform from low-end cargo ships to high-end ships such as passenger and vehicle ferries and cruise ships, the construction of ship cabins is developing towards being safer, more beautiful and more comfortable. The interior decoration requires the use of corresponding wall panels to separate the space inside the ship and play the role of sound insulation, heat insulation and fire prevention. As the main decorative material of the cabin, the wall panels need to be improved in the installation node processing.

[0003] At present, the inner corners of cabin wall panels are all installed by wrapping U-profiles on the end edges of the wall panels. When installing the connection grooves, they are usually fixed at the edge with fasteners such as bolts. The bolt fixation requires drilling holes in the inner wall or even the outer wall, which not only affects the appearance, but also affects the connection efficiency and reduces the comfort of the bulkhead panels when used. At the same time, after assembly is completed, it will produce greater shaking as the ship sails, making the cabin wall panels prone to loosening during long-term driving. At this time, the gaps at the connection of the wall panels may become larger, thereby reducing the fire protection and sound insulation performance in the cabin, posing a major safety hazard. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem of enlarged gaps at panel joints in the prior art, and to propose an A60-class bulkhead fireproof partition panel structure.

[0005] To achieve the above-mentioned object, the present invention adopts the following technical solution: an A60-class bulkhead fire partition wall structure, comprising a fire wall panel and a fixed plate, wherein the side wall of the fire wall panel is fixedly connected to a U-shaped connector, and the inner wall of the U-shaped connector is fixedly connected to a reinforcing rib, and a first sliding groove is formed through the side wall of the fixed plate;

[0006] A fixing mechanism is provided inside the first chute so that the first chute can be automatically fixed when the first chute is installed.

[0007] Both ends of the reinforcing rib are provided with sealing mechanisms to ensure the sealing of the connection during installation.

[0008] Furthermore, the fixing mechanism includes a first slider, and a third chute is formed in the side wall of the first slider. A second slider is slidably connected to the inner wall of the third chute, and a first spring is fixedly connected to the side wall of the second slider. One end of the first spring away from the second slider is fixedly connected to the inner wall of the third chute. Two fixing blocks are fixedly connected to the top of the first slider. Rotating plates are rotatably connected to the tops of the two fixing blocks. A first pressing block is rotatably connected to one end of the rotating plate away from the fixing block.

[0009] Furthermore, the outer wall of the first slider is slidably connected to the inner wall of the first chute. A second chute is formed in the side wall of the first chute. The outer end of the second slider corresponds to the inner wall of the second chute. A limiting rod is slidably connected to the inner wall of the second chute. The outer wall of the limiting rod penetrates and is slidably connected to the inner wall of the fixing plate. A second spring is fixedly connected to one end of the first slider away from the fixing block, and one end of the second spring away from the first slider is fixedly connected to the inner wall of the first chute. A through groove is formed through the top of the fixing plate. The outer wall of the first pressing block is slidably connected to the inner wall of the through groove.

[0010] Furthermore, fireproof inserts are fixedly connected to both side walls of the fixing plate close to the first chute, and one end of the fireproof insert away from the fixing plate is in sliding contact with the inner wall of the U-shaped connecting piece.

[0011] Furthermore, the sealing mechanism includes a connecting block, and a third slider is slidably connected through the inside of the connecting block. A third spring is fixedly connected to one end of the third slider close to the first slider. A second pressing block is fixedly connected to one end of the third spring away from the third slider. A fourth spring is fixedly connected to the inside of the second pressing block, and a fixing rod is fixedly connected to one end of the fourth spring away from the second pressing block. A guide rod is fixedly connected to the outer wall of the fixing rod, and a resisting block is slidably connected to the outer wall of the guide rod. A tension spring is fixedly connected to one side of the resisting block close to the fixing rod, and one end of the tension spring away from the resisting block is fixedly connected to the outer wall of the fixing rod. A clamping groove is formed through the inside of the connecting block.

[0012] Furthermore, one end of the fixing rod away from the fourth spring is fixedly connected to the inside of the connecting block. One end of the second pressing block away from the third spring corresponds to the inclined surface of the resisting block. The outer wall of the resisting block penetrates and is slidably connected to the inside of the connecting block.

[0013] Furthermore, one end of the limiting rod corresponds to the inclined surface of the second slider, and the other end of the limiting rod corresponds to the inner wall of the clamping groove.

[0014] Furthermore, one end of the connecting block away from the third slider is fixedly connected to the inner wall of the U-shaped connecting piece, and the other end of the connecting block corresponds to the side wall of the first extrusion block. One side of the two connecting blocks close to each other is fixedly connected to the end of the reinforcing rib.

[0015] Furthermore, fireproof cotton is arranged between the two fireproof wall panels, and the fireproof cotton is connected to the fireproof wall panel through a flame retardant adhesive. A fireproof coating is sprayed on the side of the fireproof wall panel away from the fireproof cotton.

[0016] Compared with the prior art, the above scheme has the following beneficial effects:

[0017] 1. During installation, due to the elastic force generated by the first spring, the second slider pops out along the inner wall of the third chute, thereby squeezing the limiting rod through its inclined surface. After being squeezed, the limiting rod slides upward into the inner part of the card slot, thus completing the automatic fixation during installation, achieving automatic locking when the component reaches the correct installation position, improving the trial-and-error space during installation, and at the same time, without the need to use multiple bolts or welding, effectively improving the installation efficiency.

[0018] 2. During installation, the extrusion force received by the abutting block from the second extrusion block is converted into the extrusion force on the fireproof insert, enabling the fireproof insert to tightly fit against the inner walls of the two U-shaped connecting pieces, blocking the gap between the two U-shaped connecting pieces with the fireproof insert, thereby ensuring the sealing performance of the bulkhead. In case of a fire later, it can prevent the smoke and toxic gases in the fire from spreading through the gap. In a high-temperature environment, the fireproof insert can quickly expand to form a dense heat insulation layer, effectively blocking the spread of flames and heat. After installation, the abutting block can continuously provide an extrusion force on the fireproof insert, enabling the fireproof insert to still fit the gap even when deformed, thus better corresponding to resist the expansion, stretching, and twisting damage to the interface structure caused by the deformation of the plate due to the fire, effectively improving the fireproof effect.

[0019] 3. When disassembly, repair, or layout adjustment is required, the operator presses the limiting rod on the inner wall of the card slot with a tool, causing the limiting rod to slide back. Then, pulling the tool drives the sealing mechanism to disconnect from the fixing mechanism. After that, the abutting block slides back through the pulling force of the tension spring and then slides along the outer wall of the guide rod into the inside of the connecting block, canceling the extrusion effect on the fireproof insert. Then, the elastic reset of the second spring drives the first slider to slide upward, causing the rotating plate to drive the first extrusion block to reset, thus automatically resetting while disassembling and quickly completing the disassembly work without damaging the component.

[0030] Example 1, please refer to Figures 1-4, a bulkhead fire partition board structure of Class A60, including a fire wall board 1 and a fixing plate 4. A U-shaped connecting piece 2 is fixedly connected to the side wall of the fire wall board 1, and a reinforcing rib 3 is fixedly connected to the inner wall of the U-shaped connecting piece 2. A first sliding groove 5 is penetrated and opened on the side wall of the fixing plate 4. Fireproof inserts 10 are fixedly connected to both side walls of the fixing plate 4 close to the first sliding groove 5, and one end side wall of the fireproof insert 10 away from the fixing plate 4 is in fitting and sliding connection with the inner wall of the U-shaped connecting piece 2. A fireproof cotton 11 is arranged between two fire wall boards 1, and the fireproof cotton 11 is connected to the fire wall board 1 through a flame retardant adhesive. A fireproof coating is sprayed on the side of the fire wall board 1 away from the fireproof cotton 11. A fixing mechanism 6 is arranged inside the first sliding groove 5 to automatically perform snap fixation when the installation is in place;

[0031] Sealing mechanisms 9 are arranged at both ends of the reinforcing rib 3 to ensure the sealing performance of the connection during installation. The sealing mechanism 9 includes a connecting block 901. A clamping groove 910 is penetrated and opened inside the connecting block 901. One end of the limiting rod 608 corresponds to the inclined surface of the second slider 603, and the other end of the limiting rod 608 corresponds to the inner wall of the clamping groove 910;

[0032] The fixing mechanism 6 includes a first slider 601. A third sliding groove 602 is opened on the side wall of the first slider 601. A second slider 603 is slidably connected to the inner wall of the third sliding groove 602. A first spring 604 is fixedly connected to the side wall of the second slider 603. One end of the first spring 604 away from the second slider 603 is fixedly connected to the inner wall of the third sliding groove 602. Two fixing blocks 605 are fixedly connected to the top of the first slider 601. Rotating plates 606 are rotatably connected to the tops of the two fixing blocks 605. A first extrusion block 607 is rotatably connected to one end of the rotating plate 606 away from the fixing block 605. The outer wall of the first slider 601 is slidably connected to the inner wall of the first sliding groove 5. A second sliding groove 7 is opened on the side wall of the first sliding groove 5. The outer end of the second slider 603 corresponds to the inner wall of the second sliding groove 7. A limiting rod 608 is slidably connected to the inner wall of the second sliding groove 7. The outer wall of the limiting rod 608 is penetrated and slidably connected to the inner wall of the fixing plate 4. A second spring 609 is fixedly connected to one end of the first slider 601 away from the fixing block 605, and one end of the second spring 609 away from the first slider 601 is fixedly connected to the inner wall of the first sliding groove 5. A through groove 8 is penetrated and opened on the top of the fixing plate 4. The outer wall of the first extrusion block 607 is slidably connected to the inner wall of the through groove 8;

[0033] When the bulkhead needs to be installed, it is necessary to connect and assemble the frames composed of multiple fireproof wall panels 1 and U-shaped connectors 2. Then, align the two U-shaped connectors 2 of the two groups of frames. Since there is fireproof cotton 11 between the frame composed of the fireproof wall panel 1 and the U-shaped connector 2, it can have good sound insulation performance and at the same time improve the flame retardant and fireproof performance of the bulkhead. By spraying fireproof paint on the exposed surface of the fireproof wall panel 1, the fireproof performance of the bulkhead surface can be improved, enhancing its resistance to fire and high temperature. Then, insert the fireproof insert 10 between the reinforcing rib 3 and the U-shaped connector 2, and at the same time move the fixing plate 4 to a position corresponding to the side wall of the reinforcing rib 3. After that, move the two U-shaped connectors 2 towards each other. When moving a certain position, at this time, the approaching ends of the two connecting blocks 901 will contact the side wall of the corresponding first extrusion block 607. During a certain subsequent process, the connecting block 901 will drive the first extrusion block 607 to move synchronously. Then, when the two first extrusion blocks 607 are subjected to a driving force, they will slide towards each other along the inner wall of the through groove 8. At the same time, the two first extrusion blocks 607 will drive the corresponding fixing blocks 605 to move downward through the rotating plate 606, thereby driving the first slider 601 to slide downward along the inner wall of the first chute 5. At the same time, the second spring 609 will be compressed. After that, when the two connecting blocks 901 move and fit together, at this time, the first slider 601 will drive the second slider 603 to move to a position corresponding to the second chute 7. Then, the first spring 604 is no longer limited, and then it will continue to release the elastic force generated by compression, so that the second slider 603 pops out along the inner wall of the third chute 602. When the second slider 603 pops out, a part of it will enter the inside of the second chute 7, thereby squeezing the limiting rod 608 through its inclined surface. When the limiting rod 608 is squeezed, it will slide upward. At this time, the two connecting blocks 901 have completed the movement. Then, the non-squeezed end of the limiting rod 608 will protrude from the top of the fixing plate 4 and then enter the inside of the card slot 910, thus completing the automatic fixation during installation, realizing that when the components reach the correct installation position, they can be automatically locked.

[0034] Embodiment 2. Please refer to Figure 3 , Figure 5 and Figure 6, on the basis of the first embodiment, in this embodiment, a third slider 902 is slidably connected through the inside of the connection block 901. One end of the third slider 902 close to the first slider 601 is fixedly connected to a third spring 903. One end of the third spring 903 away from the third slider 902 is fixedly connected to a second extrusion block 904. A fourth spring 905 is fixedly connected inside the second extrusion block 904. One end of the fourth spring 905 away from the second extrusion block 904 is fixedly connected to a fixing rod 906. A guide rod 907 is fixedly connected to the outer wall of the fixing rod 906. A contact block 908 is slidably connected to the outer wall of the guide rod 907. One side of the contact block 908 close to the fixing rod 906 is fixedly connected to a tension spring 909. One end of the tension spring 909 away from the contact block 908 is fixedly connected to the outer wall of the fixing rod 906. One end of the fixing rod 906 away from the fourth spring 905 is fixedly connected inside the connection block 901. One end of the second extrusion block 904 away from the third spring 903 corresponds to the inclined surface of the contact block 908. The outer wall of the contact block 908 is slidably connected through the inside of the connection block 901. One end of the connection block 901 away from the third slider 902 is fixedly connected to the inner wall of the U-shaped connecting piece 2. And the other end of the connection block 901 corresponds to the side wall of the first extrusion block 607. One side of the two connection blocks 901 close to each other is fixedly connected to the end of the reinforcing rib 3;

[0035] During the installation of the bulkhead, when the two sealing mechanisms 9 are driven to move relative to each other by the U-shaped connecting member 2, the two third sliders 902 will align and come into contact in advance before the two connecting blocks 901 are in contact. During the subsequent movement, the two third sliders 902 will squeeze against each other, and then the two third sliders 902 will slide into the corresponding connecting blocks 901, squeezing the third spring 903. Then, the third spring 903 will drive the second extrusion block 904 to slide synchronously through the extrusion force, so that the end of the second extrusion block 904 close to the abutting block 908 squeezes the inclined surface of the abutting block 908, and at the same time, the fourth spring 905 will be squeezed. When the abutting block 908 is squeezed, it will slide outward along the outer wall of the guide rod 907, and the tension spring 909 will be stretched during the process. After sliding a certain distance, the outer end of the abutting block 908 will protrude from the side wall of the connecting block 901, and then it will contact the fireproof plug 10. The extrusion force received by the abutting block 908 from the second extrusion block 904 is converted into the extrusion force on the fireproof plug 10. After the installation is completed, the abutting block 908 can continuously squeeze the fireproof plug 10, so that the fireproof plug 10 can closely fit on the inner walls of the two U-shaped connecting members 2, blocking the gap between the two U-shaped connecting members 2 and sealing the space between the two U-shaped connecting members 2, thus ensuring the sealing performance of the bulkhead. In case of a fire, it can prevent the smoke and toxic gases in the fire from diffusing through the gap. In a high-temperature environment, the fireproof plug 10 can quickly expand to form a dense heat-insulating layer, effectively blocking the spread of flames and heat.

[0036] Embodiment 3. Please refer to Figures 4-6 , on the basis of Embodiment 2, in this embodiment, during the use of the bulkhead, when disassembly, repair or layout adjustment is required, the operator presses the limiting rod 608 on the inner wall of the card slot 910 with a tool, causing the limiting rod 608 to slide in a reset manner. When the limiting rod 608 disengages from the card slot 910, the limiting rod 608 will stop clamping the connecting block 901. Then, the operator can pull the tool to drive the sealing mechanism 9 to disengage from the fixing mechanism 6, and at the same time, the two contacting sealing mechanisms 9 are also separated. Then, the third slider 902 and the second extrusion block 904 will slide in a reset manner through the elastic forces of the third spring 903 and the fourth spring 905. After that, the abutting block 908 will slide in a reset manner through the pulling force of the tension spring 909, and then slide along the outer wall of the guide rod 907 into the connecting block 901, thus canceling the extrusion effect on the fireproof plug 10. After the connecting block 901 disengages from the first extrusion block 607, the elastic force reset of the second spring 609 will drive the first slider 601 to slide upward along the inside of the first chute 5, causing the rotating plate 606 to drive the first extrusion block 607 to reset, so that the disassembly can be automatically reset while the disassembly is carried out, and the disassembly work can be quickly completed without damaging the components.

[0037] The working principle of the present invention is as follows: By moving two U-shaped connectors 2 towards each other, when they move to a certain position, at this time, the approaching ends of the two connecting blocks 901 will contact the side walls of the corresponding first extrusion blocks 607. During a certain subsequent process, the connecting blocks 901 will drive the first extrusion blocks 607 to move synchronously. Then, when the two first extrusion blocks 607 are subjected to a driving force, they will slide along the inner wall of the through groove 8 towards each other. At the same time, the two first extrusion blocks 607 will drive the corresponding fixed blocks 605 to move downward through the rotating plates 606, thereby driving the first sliders 601 to slide downward along the inner wall of the first chute 5. At the same time, the second spring 609 will be compressed. After that, when the two connecting blocks 901 move to fit together, at this time, the first slider 601 will drive the second slider 603 to move to a position corresponding to the second chute 7. Then, the first spring 604 is no longer limited, and then it will continue to release the elastic force generated by compression, causing the second slider 603 to pop outwards along the inner wall of the third chute 602. When the second slider 603 pops outwards, a part of it will enter the inside of the second chute 7, thereby squeezing the limiting rod 608 through its inclined surface. When the limiting rod 608 is squeezed, it will slide upwards. At this time, the two connecting blocks 901 have completed their movement. Then, the end of the limiting rod 608 that is not squeezed will protrude from the top of the fixing plate 4 and then enter the inside of the card slot 910, thus completing the automatic fixing during installation, realizing that when the components reach the correct installation position, they can be automatically locked;

[0038] During the process of driving two sealing mechanisms 9 to move relative to each other by the U-shaped connecting member 2, the two third sliders 902 will align and come into contact in advance before the two connecting blocks 901 are in contact. During the subsequent movement, the two third sliders 902 will squeeze each other, and then the two third sliders 902 will slide into the corresponding connecting blocks 901, and then squeeze the third spring 903. Then, the third spring 903 will drive the second extrusion block 904 to slide synchronously through the extrusion force, so that the end of the second extrusion block 904 close to the abutting block 908 squeezes the inclined surface of the abutting block 908, and at the same time, the fourth spring 905 will be squeezed. When the abutting block 908 is squeezed, it will slide outward along the outer wall of the guide rod 907, and the tension spring 909 will be stretched during the process. After sliding a certain distance, the outer end of the abutting block 908 will protrude from the side wall of the connecting block 901, and then it will contact the fireproof insert 10, and the extrusion force received by the abutting block 908 from the second extrusion block 904 will be converted into the extrusion force on the fireproof insert 10. After the installation is completed, the abutting block 908 can continuously squeeze the fireproof insert 10, so that the fireproof insert 10 can tightly fit on the inner walls of the two U-shaped connecting members 2, and the gap between the two U-shaped connecting members 2 is blocked by the fireproof insert 10, sealing the space between the two U-shaped connecting members 2, thereby ensuring the sealing performance of the bulkhead.

And the circuit connection relationships of each device all belong to simple series and parallel connection circuits, and there is no innovation point in the circuit connection part, which can be easily realized by those skilled in the art and belongs to the prior art, so it will not be elaborated here.

Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention should be subject to the scope defined by the claims.
