Description

Technical Field

[0001] This invention relates to the field of seawater desalination equipment technology, and more specifically, to a marine seawater desalination equipment. Background Technology

[0002] Marine desalination units are specialized seawater desalination equipment used on ships, yachts, and offshore oil drilling platforms. They employ ambient temperature reverse osmosis membrane separation technology to desalinate seawater, producing freshwater that meets national drinking water standards. The process includes pretreatment sterilization, double-layer filtration, and two-stage reverse osmosis treatment, with turbidity reduced through a sodium hypochlorite generator and activated carbon filtration system. Currently, marine desalination units can be installed in either a centralized or modular manner depending on the ship's dimensions. Centralized installation increases the integration of the desalination unit, concentrating its footprint in one location. However, this method results in overly concentrated components, often located in corners of the ship's hold. Since the reverse osmosis membrane is the core component of desalination and requires regular replacement (otherwise, the efficiency and quality of desalination will be affected), the highly integrated installation makes maintenance and replacement of the reverse osmosis membrane difficult. While modular installation facilitates maintenance, the looser installation makes it difficult to adjust or relocate components when the ship's space is redesigned.

[0003] According to Chinese Publication No. CN119569182A, a marine emergency electric seawater desalination tank includes a tank assembly, a membrane assembly, a battery assembly, a pump motor assembly, an electrical control box assembly, and a mounting frame assembly. It uses electricity as the energy source for seawater desalination, eliminating the need for a continuous power supply and manual operation by installing a rechargeable battery. This meets the emergency use requirements for seawater desalination at sea and in the field. This emergency device changes the power supply method, process, and layout, using electricity to drive the desalination device and designing a rechargeable power supply to ensure convenient use in confined, dimly lit, and swaying environments on ships. Within a limited space, the membrane device adopts a three-section series arrangement, achieving high water production efficiency while reducing energy consumption and size.

[0004] The aforementioned applications enable the seawater desalination device to meet emergency needs through rechargeable batteries and improve the integration of the device through centralized layout to reduce the device size. However, this highly integrated installation makes it difficult to disassemble the reverse osmosis membrane during maintenance, which is inconvenient for maintenance and replacement, thus prolonging the maintenance time and affecting the normal desalination of seawater. Therefore, in order to address this problem, this application provides a marine seawater desalination device to meet the requirements. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the embodiments of the present invention provide a marine seawater desalination device, which improves the convenience of disassembling and replacing the reverse osmosis membrane by connecting components and fixing components, and can reduce the integration of the device, so as to facilitate the adjustment of the device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A marine seawater desalination device includes a first frame, a second frame disposed on one side of the first frame, a main body disposed on the inner side of the first frame, a connecting assembly disposed on one side of the first frame, and a fixing assembly disposed on the inner side of the second frame. The connecting assembly includes a side connecting plate fixedly connected to one side of the first frame, a limiting post fixedly connected to one side of the side connecting plate, the limiting post having a cylindrical profile, a limiting sliding plate slidably connected to one side of the side connecting plate, the limiting sliding plate being sleeved on the outside of the limiting post, a connecting frame hinged to one side of the limiting sliding plate, a pull rod fixedly connected to the bottom end of the connecting frame, a fixing side plate fixedly connected to one side of the second frame, and a first limiting frame fixedly connected to one end of the fixing side plate.

[0007] In a preferred embodiment, a second limiting frame is fixedly connected to the end of the fixed side plate away from the first limiting frame, and the limiting slide plate is inserted into the inner side of the first limiting frame.

[0008] In a preferred embodiment, a positioning post is fixedly connected to one side of the side connecting plate, and the positioning post is slidably connected inside the first frame.

[0009] In a preferred embodiment, a square slider is slidably connected inside the side connecting plate, and a positioning pin is fixedly connected inside the square slider. The positioning pin is slidably connected inside the first frame.

[0010] In a preferred embodiment, a fastener is fixedly connected to one side of the second frame, the fastener is inserted into the interior of the first frame, and the positioning pin is inserted into the inner side of the fastener.

[0011] In a preferred embodiment, the fixing assembly includes a support rod fixedly connected to the inside of the second frame, and a fixing strap is fixedly connected to the top of the support rod, the fixing strap being fitted to the reverse osmosis membrane.

[0012] In a preferred embodiment, the support rod is rotatably connected to a rotating shaft inside, a reference block is fixedly connected to the outside of the rotating shaft, a support plate is fixedly connected to one side of the reference block, and the support plate is arranged in contact with the reverse osmosis membrane.

[0013] In a preferred embodiment, a fixing buckle is rotatably connected to the outer side of the reference block, and a hook plate is fixedly connected to one end of the fixing strap, the hook plate being sleeved on the outer side of the fixing buckle.

[0014] In a preferred embodiment, a limiting crossbar is slidably connected inside the support rod. The limiting crossbar is arranged in an abutting position with the reference block. Both ends of the limiting crossbar are fixedly connected with studs, and nuts are threadedly connected to the outer side of the studs.

[0015] The technical effects and advantages of this invention are as follows: This invention, by setting up a connecting component, allows for maintenance or replacement of reverse osmosis membranes. When maintenance or replacement is required, pulling a lever to one side disengages the limiting slide plate from the inside of the first limiting frame. Pulling the limiting slide plate perpendicular to the first frame separates the positioning pin from the fixing component, thus removing the limiting relationship between the fixing component and the first frame. Pushing the second frame causes the fixing component to slide out from the inside of the first frame, separating the first and second frames. This allows multiple reverse osmosis membranes to be pulled out from the back of the first frame by pulling the second frame, enabling direct maintenance and replacement of multiple reverse osmosis membranes. This avoids situations where the high integration of the seawater desalination device or the installation location affects the maintenance and replacement of the reverse osmosis membranes. When installing the second frame into the interior of the first frame, the limiting slide plate is first connected to the first limiting frame to facilitate the positioning of the second frame. After the limiting slide plate is inserted into the first limiting frame, the second frame is pushed until the side connecting plate is in contact with the first frame and then stops. At this time, the fastener and the first frame are in an overlapping and corresponding state. By pulling the second frame, the fastener can be inserted into the interior of the first frame, which facilitates the installation of the second frame and makes it easy to position the first and second frames. When the fastener is inserted into the interior of the first frame, it will contact the positioning pin. The positioning pin limits the fastener, and the limiting slide limits the first limiting frame, thereby improving the firmness of the connection between the first frame and the second frame and preventing the first frame from separating due to the hull swaying.

[0016] In summary, separating the first and second frames improves the ease of maintenance and replacement of the reverse osmosis membrane, thereby increasing the efficiency of maintenance and replacement. This reduces the impact of stopping seawater desalination during maintenance. Furthermore, the ease of maintenance and replacement helps ensure the quality and efficiency of seawater desalination, providing crew members with sufficient fresh water. Attached Figure Description

[0019] 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 some embodiments of the present invention, and not all embodiments. 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.

[0020] Refer to the instruction manual appendix Figures 1-10 As shown, a marine seawater desalination device according to an embodiment of the present invention includes a first frame 1, a second frame 2 disposed on one side of the first frame 1, a main body 3 disposed on the inner side of the first frame 1, the main body 3 being composed of a freshwater pump, a filter bottle, a booster pump, a water tank, an operation and testing cabinet, etc., a connecting component disposed on one side of the first frame 1, and a fixing component disposed on the inner side of the second frame 2.

[0021] The connecting assembly includes a side connecting plate 5 fixedly connected to one side of the first frame 1. A limiting post 6 is fixedly connected to one side of the side connecting plate 5. The limiting post 6 has a cylindrical profile. A limiting slide plate 7 is slidably connected to one side of the side connecting plate 5. The limiting slide plate 7 is sleeved on the outside of the limiting post 6. A connecting frame 8 is hinged to one side of the limiting slide plate 7. A pull rod 9 is fixedly connected to the bottom end of the connecting frame 8. The limiting slide plates 7 on the upper and lower sides of one side of the first frame 1 are connected through the connecting frame 8 and the pull rod 9. A fixed side plate 10 is fixedly connected to one side of the second frame 2. A first limiting frame 11 is fixedly connected to one end of the fixed side plate 10. A second limiting frame 12 is fixedly connected to the end of the fixed side plate 10 away from the first limiting frame 11. The first limiting frame 11 and the second limiting frame 12 have the same structure. The limiting slide plate 7 is inserted into the inside of the first limiting frame 11.

[0022] A positioning post 13 is fixedly connected to one side of the side connecting plate 5. The positioning post 13 is slidably connected inside the first frame 1. A square slider 14 is slidably connected inside the side connecting plate 5. A positioning pin 15 is fixedly connected inside the square slider 14. The positioning pin 15 is slidably connected inside the first frame 1. A fixing member 16 is fixedly connected to one side of the second frame 2. The fixing member 16 is inserted into the first frame 1. The positioning pin 15 is inserted into the inner side of the fixing member 16.

[0023] It should be noted that when maintenance or replacement of the reverse osmosis membrane 4 is required, the pull rod 9 can be pulled to one side, causing the upper and lower limiting slide plates 7 to slide to one side under the action of the connecting frame 8 until they disengage from the inside of the first limiting frame 11. At this time, by pulling the limiting slide plates 7 in a direction perpendicular to the first frame 1, the positioning pin 15 is driven out from the inside of the first frame 1 through the side connecting plate 5 until it separates from the fixing member 16. This allows the fixing member 16 to lose its limiting relationship with the first frame 1. By pushing the second frame 2, the fixing member 16 is moved out of the inside of the first frame 1. Sliding out allows the first frame 1 to separate from the second frame 2. Since the second frame 2 is supported by multiple pulleys 30, the rotation of the pulleys 30 allows multiple reverse osmosis membranes 4 to be pulled out from the back of the first frame 1. This enables direct maintenance and replacement of the multiple reverse osmosis membranes 4, avoiding situations where the high integration of the seawater desalination unit or the installation location affects the maintenance and replacement of the reverse osmosis membranes 4. It should be noted that before separating the first frame 1 from the second frame 2, the pipes connecting the reverse osmosis membranes 4 to the main body 3 must be disassembled.

[0024] After the reverse osmosis membrane 4 is maintained and replaced, when installing and fixing the second frame 2, due to its large size, it is inconvenient to simultaneously insert the four corner fixing pieces 16 into the first frame 1. Therefore, the second frame 2 can be pushed to the back of the first frame 1, and the side connecting plate 5 can be pulled to separate it from the first frame 1. By displacing the side connecting plate 5, the limiting slide plate 7 is made to coincide with the first limiting frame 11, allowing the limiting slide plate 7 to preferentially insert into the inner side of the first limiting frame 11. This allows the limiting slide plate 7 to preferentially connect with the first limiting frame 11 by moving the side connecting plate 5 and the limiting slide plate 7, facilitating the positioning of the second frame 2. After the limiting slide plate 7 is inserted into the first limiting frame 11, the second frame 2 can be further pushed until the side connecting plate 5 is in contact with the first frame 1. After the assembly stops, the fastener 16 and the first frame 1 are in an overlapping and corresponding state. By pulling the second frame 2, the fastener 16 can be inserted into the interior of the first frame 1, which facilitates the installation of the second frame 2. When the fastener 16 is inserted into the interior of the first frame 1, it will contact the positioning pin 15. The inclined surface of the fastener 16 guides the positioning pin 15, causing the positioning pin 15 to gradually rise. After the fastener 16 is fully inserted into the interior of the first frame 1, the positioning pin 15 falls into the inner side of the fastener 16, completing the fixation of the fastener 16. In this way, the positioning pin 15 limits the fastener 16, and the limiting slide plate 7 limits the first limiting frame 11, thereby improving the firmness of the connection between the first frame 1 and the second frame 2 and preventing the first frame 1 and the second frame 2 from separating due to the swaying of the hull.

[0025] In summary, separating the first frame 1 from the second frame 2 improves the convenience of maintaining and replacing the reverse osmosis membrane 4, thereby increasing the efficiency of maintenance and replacement. This reduces the impact of stopping seawater desalination during maintenance. Furthermore, maintaining and replacing the reverse osmosis membrane 4 helps ensure the quality and efficiency of seawater desalination, enabling crew members to have sufficient fresh water.

[0026] The connecting components also enable the seawater desalination unit to have two installation states. Figure 1 The diagram shows a centralized installation method for a seawater desalination unit. When the ship's cabin space cannot accommodate a centralized installation, the seawater desalination unit can be installed in a separate manner by separating the first frame 1 and the second frame 2. This also allows for flexibility in installation in different ship cabin spaces. By making the first frame 1 and the second frame 2 side by side, the limiting slide plate 7 is inserted into the inside of the second limiting frame 12, thus maintaining the connection between the first frame 1 and the second frame 2. This allows the first frame 1 and the second frame 2 to remain connected when the ship's cabin space permits, thereby improving the stability of the first frame 1 and the second frame 2 to withstand frequent swaying of the ship.

[0027] Furthermore, such as Figure 3 As shown, the fixing assembly includes a support rod 17 fixedly connected to the inner side of the second frame 2. A fixing strap 19 is fixedly connected to the top of the support rod 17. The fixing strap 19 is fitted to the reverse osmosis membrane 4. A rotating shaft 20 is rotatably connected inside the support rod 17. A reference block 23 is fixedly connected to the outer side of the rotating shaft 20. A support plate 24 is fixedly connected to one side of the reference block 23. The support plate 24 is in contact with the reverse osmosis membrane 4. A fixing buckle 25 is rotatably connected to the outer side of the reference block 23. A hook plate 26 is fixedly connected to one end of the fixing strap 19. The hook plate 26 is sleeved on the outer side of the fixing buckle 25. A limiting crossbar 27 is slidably connected inside the support rod 17. The limiting crossbar 27 is in contact with the reference block 23. Studs 28 are fixedly connected to both ends of the limiting crossbar 27. Nuts 29 are threadedly connected to the outer side of the studs 28.

[0028] It should be noted that, when disassembling the reverse osmosis membrane 4 after separating the first frame 1 from the second frame 2, the membrane 4 can be removed by separating the fixing buckle 25 from the hook plate 26. Simultaneously, the reference block 23 and the support plate 24 limit the reverse osmosis membrane 4 to prevent it from rolling off the top of the support rod 17 after losing the restraint of the fixing strap 19. At this point, the membrane 4 can be lifted for disassembly, or the limiting crossbar 27 can be pushed to the other end by loosening the nut 29, causing the reference block 23 to flip downwards after losing the restraint of the limiting crossbar 27, thus losing its resistance to the reverse osmosis membrane 4. The membrane 4 can then be pulled out from the top of the support rod 17. Similarly, when installing the reverse osmosis membrane 4, it is placed on the top of the support rod 17 in contact with the limiting block 18, and the limiting crossbar 27 is pulled to... Figure 7 At the indicated position, tighten the nut 29 to fix the limiting crossbar 27. The limiting crossbar 27 keeps the reference block 23 and the support plate 24 in contact with the reverse osmosis membrane 4, thereby initially limiting the reverse osmosis membrane 4. Then, by connecting the hook plate 26 to the fixing buckle 25, the reverse osmosis membrane 4 can be fixed.

[0029] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
