Description

Technical Field

[0001] This invention relates to the field of marine technology, specifically to a folding cofferdam for ships. Background Technology

[0002] Ships are a general term for all kinds of vessels. They are means of transportation capable of navigating or anchoring on waterways for transport or operations, and vary in technical performance, equipment, and structural type according to different usage requirements. Ships are man-made means of transportation that primarily operate in geographical waters. Furthermore, civilian ships are generally called boats, military ships are called warships, and small boats are called dinghies or rafts; collectively, they are called ships or dinghies. Internally, they mainly include storage space, supporting structures, and drainage structures, and have a propulsion system that utilizes external or internal energy. Their shape is generally a streamlined envelope that helps overcome fluid resistance. Materials are constantly updated with technological advancements; early materials included natural materials such as wood, bamboo, and hemp, while modern materials are mostly steel, aluminum, fiberglass, acrylic, and various composite materials. From prehistoric times when boats were carved from logs, through the era of dugout canoes and plank boats, the era of steel ships as the primary mode of transportation began after the world's first steel ship was built in 1879. Ship propulsion has also evolved from relying on human, animal, and wind power (i.e., punting, rowing, rubbing, towing, and sailing) in the 19th century to using machine propulsion.

[0003] As the primary means of transportation in international trade, ships have a global demand. Shipbuilding is mainly concentrated in China, Japan, and South Korea due to different comparative advantages in construction. However, ship products circulate globally.

[0004] Chinese patent CN111717522A discloses a folding enclosure box for honeycomb panels, comprising a fixed locking mounting base, a suction cup-type anti-displacement and shock-absorbing support device, a filling-type folding placement device, a rotating fastening device, a telescopic compression fastening device, and a locking and sealing top cover. This invention belongs to the technical field of folding enclosure boxes, specifically a folding enclosure box for honeycomb panels. It employs a filling-type folding placement method to achieve the desired folding effect. The suction cup-type anti-displacement and shock-absorbing support device provides shock absorption and anti-displacement. The combination of a locking placement groove and a telescopic compression fastening device effectively secures the honeycomb panels, solving the problems of poor performance, complex structure, and inconvenient maintenance of current folding enclosure boxes for honeycomb panels on the market.

[0005] Regarding the aforementioned technologies, it has been found that to adapt to market development needs, cabin metal composite panels have always been installed in a fixed manner, or an opening is cut into the fixed metal composite panel as an inspection hole, and then an inspection door is manufactured and installed for the inspection area. However, in actual shipboard applications, limitations are often encountered, especially when the inspection area is particularly large or scattered. In such cases, it is necessary to install folding panels to overcome the limitations of fixed panels, as scattered folding panels are not convenient to lock and secure. Summary of the Invention

[0006] To address the aforementioned technical issues, it has been found that, to meet market demands, cabin metal composite panels have traditionally been installed in a fixed manner, or an opening is cut into the fixed metal composite panel as an inspection hole, followed by the fabrication and installation of an inspection door for the inspection area. However, in actual shipboard applications, limitations are frequently encountered, especially when the inspection area is particularly large or dispersed. This necessitates the installation of folding panels to overcome the limitations of fixed panels. This application provides a folding panel for ships, comprising the panel itself, and further comprising:

[0007] The folding panels are installed in two sets at the top and bottom of the enclosure to assist in folding and installing the enclosure.

[0008] A sliding wheel is installed at the center of the bottom of the folding panel to assist in sliding the folding panel.

[0009] The mounting rail is slidably mounted on the bottom of the sliding wheel to define the position of the enclosure panel;

[0010] A limiting seat, fixedly installed on the ship, is used to compress and limit the installation of the mounting rail;

[0011] A locking structure is fixedly installed on one side of the enclosure panel for locking the enclosure panel.

[0012] Furthermore, the folding assembly includes placement slots formed inside both ends of the folding assembly, storage slots formed at the top and bottom of the placement slots for assisting sliding, and a sliding opening formed between the storage slots and the placement slots.

[0013] Furthermore, a flipping shaft is slidably installed on both the storage slot and the sliding opening, a flipping frame is installed on the placement slot, a flipping block is flipped on the flipping frame, and a folding frame is installed on the flipping block. The folding frames are folded and stretched together by rotating a knob.

[0014] Furthermore, the sliding wheel includes a rotating block mounted on top for rotating the folding assembly, a mounting plate frame mounted on the bottom of the rotating block, two sets of mounting covers fixedly mounted on the bottom of the mounting plate frame, and a set of rollers mounted on the bottom of the mounting covers for sliding.

[0015] Furthermore, a column is installed at the center of the bottom of the mounting cover, and a ball bearing is rotatably installed at the end of the column.

[0016] Furthermore, the mounting track includes a limiting plate installed at the end and two sets of sliding tracks installed between the limiting plates.

[0017] Furthermore, the sliding track includes upright plates installed on both sides, two sets of sliding grooves formed between the upright plates, three sets of through openings at the top of the sliding grooves, and ball grooves at the top of the through openings.

[0018] Furthermore, the slide groove and the roller assembly are slidably installed together, and the ball groove and the ball block are slidably installed together.

[0019] Furthermore, the limiting seat includes two sets of mounting plates welded to both ends, two sets of mounting holes opened on the mounting plates, a compression limiting block snapped between the limiting seat and the mounting track, a compression layer installed on one side of the compression limiting block, a snap-fit ​​layer welded to one side of the compression limiting block, and a fastening deformation block for compression force placed inside the compression limiting block on one side of the snap-fit ​​layer.

[0020] Furthermore, a fitting groove is provided on one side of the enclosure, and a fitting plate is fixedly installed on the other side. Locking holes are provided in the fitting groove and the fitting plate. The locking structure includes a welding block welded to the enclosure. A limit hole is provided inside the welding block. A limit post and a locking rod are installed through the welding block and the locking hole. A clamping block is installed at the end of the locking rod through two sets of rotating blocks. A connecting spring is connected between the clamping blocks. An installation ring is fixedly installed inside the limit post. A locking block is installed around the outside of the installation ring through multiple sets of return springs.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] Firstly, in this invention, a flipping shaft is slidably installed on both the storage slot and the sliding opening. A flipping frame installed on the placement slot cooperates with a flipping block, causing the folding frame installed on the flipping block to fold and stretch with a rotating knob, achieving the folding effect of the enclosure. The folded enclosure is then folded as a whole by a rotating block installed on top via sliding wheels, which is used to rotate the folding panel. The folded enclosure has a large open space, ensuring the folding effect of the enclosure while maximizing the unfolded area to increase the opening area, facilitating entry and exit from the enclosure's restricted area.

[0023] Secondly, in this invention, a sliding opening is formed between the top and bottom of the placement slot and the storage slot to assist sliding. The end of the flip shaft is limited by the sliding opening and the end of the storage slot, ensuring that the flip frame slides and is stored inside the placement slot. This facilitates seamless connection of the enclosure panels and ensures a tight fit between the panels. The sliding groove and roller assembly cooperate to slide and install, and the ball groove and ball block cooperate to slide and install. This ensures that when the sliding wheel at the bottom of the enclosure panel slides, the engagement effect between the ball groove and the ball block is increased, the support force is increased, and the stability of the sliding wheel during sliding is improved.

[0024] Thirdly, in this invention, a compression limiting block is snapped between the limiting seat and the mounting rail, a compression layer is installed on one side of the compression limiting block, and a snap-fit ​​layer plate is welded to one side of the compression limiting block. Inside the compression limiting block on the snap-fit ​​layer plate, a fastening deformation block for compression force is placed, which increases the fastness between the limiting seat and the mounting rail, ensuring that after the limiting seat is stably installed, the bottom of the enclosure is more stable when it is folded for use.

[0025] Fourth, in this invention, the surrounding panels are connected and installed by means of a fitting groove and a fitting plate, and the two sets of surrounding panels are locked by means of a locking rod passing through a locking hole for limiting and fixing. The locking rod can be disassembled and installed by pressing the locking block and the clamping block, thus ensuring the stability of the surrounding panels when they do not need to be folded.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0040] Reference Figure 1-8 As shown, a folding cofferdam for ships includes cofferdam 3, and also includes:

[0041] Folding panels 4, in two sets, are installed on the top and bottom of the enclosure 3 to assist in the folding and installation of the enclosure 3. Each folding panel 4 includes placement slots 41 inside both ends of the folding panel 4, storage slots 46 at the top and bottom of the placement slots 41 for assisting sliding, and a sliding opening 45 between the storage slots 46 and the placement slots 41. Flipping shafts 44 are slidably mounted on both the storage slots 46 and the sliding openings 45. A flipping frame 42 is mounted on the placement slots 41, and flipping blocks 43 are flipped and mounted on the flipping frames 42. Folding frames 47 are mounted on the flipping blocks 43. The folding frames 47 are folded and stretched by rotating knobs 48, and the movement is achieved by the ends of the flipping shafts 44 and the sliding openings 45 and the storage slots 46. Limiting the position ensures that the flipping frame 42 slides and is stored inside the placement slot 41; through the storage slots 46 at the top and bottom of the placement slot 41 for assisting sliding, and the sliding opening 45 between the storage slot 46 and the placement slot 41, the flipping frame 42, flipping block 43 and folding frame 47 and other folding structures are stored, which facilitates the seamless connection of the enclosure 3 and ensures the tightness between the enclosure 3. The sliding groove 24 and the roller group 56 cooperate to slide and install, and the ball groove 26 and the ball block 55 cooperate to slide and install, which ensures that when the sliding wheel 5 at the bottom of the enclosure 3 slides, the engagement effect between the ball groove 26 and the ball block 55 is increased, the support force is increased, and the stability of the sliding wheel 5 is improved when sliding.

[0042] A sliding wheel 5 is installed at the center of the bottom of the folding panel 4 to assist in the sliding of the folding panel 4. The sliding wheel 5 includes a rotating block 51 installed at the top to control the rotation direction of the folding panel 4, a mounting bracket 52 installed at the bottom of the rotating block 51, two sets of mounting covers 53 fixedly installed at the bottom of the mounting bracket 52, and a roller assembly 56 installed at the bottom of the mounting cover 53 for sliding. A column rod 54 is installed at the center of the bottom of the mounting cover 53, and a ball block 55 is rotatably installed at the end of the column rod 54. The roller assembly 56 is slidably installed through the groove 24 and the ball groove 26 and the ball block 55, which are mutually engaged in sliding installation to ensure that the sliding wheel 5 at the bottom of the panel 3 slides with the ball groove 26 and the ball block engaged in sliding installation. The interlocking effect between 55 increases the support force and improves the stability of the sliding wheel 5 when sliding. The flipping shaft 44, which is slidably installed on the storage groove 46 and the sliding opening 45, is connected by the flipping frame 42 installed on the placement groove 41 and the flipping block 43. This allows the folding frame 47 installed on the flipping block 43 to be folded and stretched with the rotating knob 48, achieving the folding effect of the enclosure 3. The folded enclosure 3 is then folded as a whole by the rotating block 51 installed on the top of the sliding wheel 5 to rotate the folding assembly 4. The sliding wheel 5 slides the enclosure 3 to one end, leaving a large space after folding. This ensures the folding effect of the enclosure while maximizing the unfolding degree and increasing the opening area, making it easier to enter and exit the restricted area of ​​the enclosure 3.

[0043] The mounting track 2 is slidably installed at the bottom of the sliding wheels 5 to limit the position of the enclosure panel 3. The mounting track 2 includes a limiting plate 21 installed at the end, two sets of sliding tracks 22 installed between the limiting plates 21, and vertical plates 23 installed on both sides. Two sets of sliding grooves 24 are opened between the vertical plates 23. Three sets of through holes 25 are opened at the top of the sliding grooves 24, and ball grooves 26 are opened at the top of the through holes 25. The sliding grooves 24 and the roller assembly 56 are slidably installed in cooperation with each other, and the ball grooves 26 and the ball blocks 55 are slidably installed in cooperation with each other. The roller assembly 56 slides inside the sliding grooves 24, and the rotating block 51 drives the bottom surface of the folding panel 4 to rotate, thereby causing the enclosure panel 3 to flip.

[0044] A limiting seat 1, fixedly installed on the ship, is used for compression and limiting the installation of the mounting rail 2. The limiting seat 1 includes two sets of mounting plates 11 welded to both ends, two sets of mounting holes 12 formed on the mounting plates 11, a compression limiting block 13 snapped between the limiting seat 1 and the mounting rail 2, a compression layer 14 installed on one side of the compression limiting block 13, a snap-fit ​​layer 15 welded to one side of the compression limiting block 13, and a fastening deformation block 16 placed on one side of the snap-fit ​​layer 15 for compression force application. The fastening deformation block 16 is elastic under force and applies pressure to the compression limiting block 13. Force is applied to both ends, causing the fixed limiting seat 1 and the mounting rail 2 to press against each other, forming a counter-pressure, thereby increasing the stability of the bottom. After the limiting seat 1 is installed on the ship at a fixed position and the distance between the limiting seats 1 is limited, the mounting rail 2 is installed between the limiting seats 1 and fixed. After the limiting is fixed, the cofferdam 3 is used. When in use, the cofferdam 3 is slid and the rotating block 51 flips the cofferdam 3. The folding frame 47 between the folding panels 4 and the rotating knob 48 stretch and flip the cofferdam 3, thereby realizing the folding of the cofferdam 3 and pushing it. By bringing the panels together to one end, the enclosure 3 is folded and placed in a different direction, thereby increasing the number of openings. The shape can be arbitrarily changed to achieve the folding effect of the enclosure. The folding enclosure achieves the goal of entering another area or room without increasing material costs or requiring individual panel disassembly. The folding enclosure is designed with optimized structure and installation to allow multiple panels to be opened as a whole, enabling quick access to another area or room. The extrusion limiting block 13, which is snapped between the limiting seat 1 and the mounting rail 2, is used to connect the extrusion layer 14, which is installed on one side of the extrusion limiting block 13 and welded to the extrusion... The snap-fit ​​layer 15 on one side of the pressure limiting block 13, and the squeezing limiting block 13 on the other side of the snap-fit ​​layer 15 contains a fastening deformation block 16 for squeezing force, which increases the tightness between the limiting seat 1 and the mounting rail 2. This ensures that after the limiting seat 1 is stably installed, the bottom of the cofferdam 3 is more stable when folded. This solves the problem that, in order to adapt to the needs of market development, the metal composite panels of the cabin have always adopted a fixed installation method, or an opening is cut into the fixed metal composite panel as an inspection hole, and then an inspection door is made and installed for the inspection area. However, in actual ships, there are often limitations in application, especially when the inspection area is particularly large or particularly scattered. In this case, it is necessary to install this folding cofferdam to solve the problem of the application limitations of the fixed cofferdam.

[0045] refer to Figures 9-11The locking structure 6 is fixedly installed on one side of the enclosure 3 for locking the enclosure 3. One side of the enclosure 3 has a mating groove 32, and the other side has a mating plate 31 fixedly installed. Locking holes 33 are provided on the mating groove 32 and the mating plate 31. The locking structure 6 includes a welding block 61 welded to the enclosure 3. A limit hole 62 is provided inside the welding block 61. A limit post 63 and a locking rod 64 are installed through the welding block 61 and the locking hole 33. A clamping block 66 is installed at the end of the locking rod 64 via two sets of rotating blocks 65. A connecting spring 67 is installed between the two parts. An installation ring 631 is fixedly installed inside the limiting post 63. A locking block 632 is installed around the outside of the installation ring 631 through multiple sets of reset springs 633. The enclosure 3 is connected and installed by the engaging groove 32 and engaging plate 31. The locking rod 64 is fixed by passing through the locking hole 33 and locking the two sets of enclosure 3. The locking rod 64 can be disassembled and installed by pressing the locking block 632 and the clamping block 66, which ensures the stability of the enclosure 3 when it does not need to be folded.

[0046] Working Principle: In actual ship operations, the application limitations of fixed cofferdams are often encountered, especially when the maintenance area is particularly large or scattered. In such cases, it is necessary to install this type of folding cofferdam to overcome the application limitations of fixed cofferdams. By installing the limiting seat 1 on the ship at a fixed position and limiting the distance between the limiting seats 1, and then installing the mounting rail 2 between the limiting seats 1 to fix the limiting position, the cofferdam 3 can be used. During use, the cofferdam 3 is slid and rotated by the rotating block 51. The folding frame 47 and the rotating knob 48 between the folding panels 4 stretch and rotate the cofferdam 3, thereby achieving the folding of the cofferdam 3 and pushing it to one end, changing the direction of the folding and placing the cofferdam 3, thereby increasing the opening position and arbitrarily changing the shape to achieve the folding effect of the folding cofferdam. Finally, the locking structure 6 locks the cofferdam 3 that does not need to be folded, ensuring the stable fixing effect between the cofferdam 3.

Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
