[0022] See also Figures 1 to 5 As shown, according to an embodiment of the present invention, there is provided an underwater operation sealed cabin, comprising a cover body 1, wherein the cover body 1 has a connection opening 11 corresponding to a construction work surface, a magnetic connection component 2 is provided at the edge of the connection opening 11, and the magnetic connection component 2 can form a sealed connection with the construction work surface, and a sealing door 12 is provided in the connection opening 11, and the sealing door 12 can be closed before the magnetic connection component 2 is sealedly connected to the construction work surface, and opened after the magnetic connection component 2 is sealedly connected to the construction work surface. In this technical solution, the magnetic connection assembly 2 can form a quick and simple sealed connection with the construction work surface, and the sealing door 12 can effectively prevent the water in the underwater environment from entering the internal cavity of the cover body 1 in large quantities during the connection between the underwater operation sealed cabin and the construction work surface. After the sealing connection is completed, the sealing door is opened to expose the construction work surface to the internal cavity of the cover body 1 (that is, the construction space), thereby creating a sealed waterless space in the underwater environment. When it is applied to the underwater area of a ship, the ship can be efficiently repaired without docking, greatly reducing the maintenance construction cycle, maintenance costs and ship operating costs. The sealing door 12 is, for example, a sliding door to ensure the maximization of the working construction space in the sealed cabin, which can be opened or closed by remote control.

[0023] The magnetic connection component 2 can be, for example, a ring-shaped electromagnet. In this case, the electromagnet as a whole can resist the intrusion of external water bodies, but this method will greatly increase the manufacturing cost and difficulty of the electromagnet. Optionally, the magnetic connection component 2 includes an electromagnet 21, and the electromagnet 21 has multiple electromagnets 21. The multiple electromagnets 21 are arranged around the circumference of the connection opening 11. It can be understood that the multiple electromagnets 21 are arranged in close proximity to each other, thereby objectively achieving the technical effect of the aforementioned ring-shaped electromagnet. Of course, the sealing between the two adjacent electromagnets needs to be considered at this time. In a specific embodiment, the electromagnet 21 adopts an electromagnet model P240 / 80, which has a suction force of 3000Kg and a suction surface diameter of 120mm.

[0024] Preferably, the magnetic connection component 2 further includes an airbag 22, which is arranged around the connection opening 11, and multiple electromagnets 21 are wrapped in the airbag 22. The design of the airbag 22 can effectively solve the problem of sealing the gap between two adjacent electromagnets 21 (that is, preventing water intrusion). Furthermore, the magnetic connection assembly 2 also includes a plurality of telescopic rods 23, and the plurality of telescopic rods 23 are arranged at circumferential intervals around the connection opening 11, and one end of each telescopic rod 23 is connected to the cover body 1, and the other end of the telescopic rod 23 is connected to the electromagnet 21, and the airbag 22 is wrapped around the outside of the telescopic rod 23 and the electromagnet 21. At this time, the telescopic displacement of the telescopic rod 23 can adjust the relative space between the connection opening 11 and the construction working surface, thereby making the underwater construction space more spacious. It can be understood that the airbag 22 should have a certain elasticity to adapt to the extension amount of the telescopic rod 23, and also have a certain toughness (strength) to ensure the structural integrity during the telescopic process and improve its service life. It can be further understood that, as Figure 3 As shown, when the telescopic rod 23 is in the extended state (position), the airbag 22 effectively forms an annular water retaining wall (surrounding the connection opening 11), with the multiple telescopic rods 23 forming the framework of this water retaining wall. The telescopic rod 23 can be implemented as a linear reciprocating component, such as a pneumatic cylinder or hydraulic cylinder, though this is not particularly limited in the present invention. However, as a specific embodiment of the airbag 22, it can be inflated with a corresponding gas in sync with the extension of the telescopic rod 23, thereby enhancing the structural stability of the airbag 22 in the extended state.

[0025] Furthermore, a sealing ring 24 is provided on the side of the airbag 22 corresponding to the construction work surface. The sealing ring 24 can also be placed on the outside of the airbag 22 by, for example, gluing, to improve the sealing performance of the connection between the airbag 22 and the sealing ring 24. It is understandable that, if the material is available, the sealing ring 24 and the airbag 22 can be integrally formed. The provision of the sealing ring 24 can improve the sealing performance of the connection between the sealed cabin and the construction work surface. The sealing ring 24 is flexible and can ensure the fit of the magnetic connection assembly 2 with the construction work surface through its own deformation.

[0026] When there are multiple electromagnets 21 and the airbags 22 are wrapped around them, the adjacent intervals between the electromagnets 21 can be set larger. Under the premise of meeting the requirements of magnetic connection, the number of electromagnets 21 used can be saved, thereby reducing the manufacturing cost. Best, at least some of the multiple electromagnets 21 can be independently controlled so that the electromagnets 21 in different areas can be powered on separately. For example, when the construction work surface is in a vertical position (or a substantially vertical position), the electromagnet 21 includes a first electromagnet group horizontally arranged in the area below the connection opening 11, a second electromagnet group horizontally arranged in the area above the connection opening 11, and a third electromagnet group vertically arranged between the first electromagnet group and the second electromagnet group. During the process of sealing the magnetic connection component 2 with the construction work surface, the first electromagnet group is first energized to engage with the construction work surface, the third electromagnet group is then energized to engage with the construction work surface, and finally the second electromagnet group is controlled to engage with the construction work surface. By adopting this energization method, the water at the connection opening 11 can be forced out from the bottom to the top as much as possible during the process of sealing the magnetic connection component 2 with the construction work surface, thereby maximizing the amount of water retained in the corresponding area of the connection opening 11 during the sealing connection process.

[0027] Optionally, an assembly seat 3 is further provided on the inner wall of the cover body 1, and the assembly seat 3 is used to assemble and connect a manipulator 31. Specifically, for example, the assembly seat 3 is provided on the inner wall of the cover body 1 opposite to the connection opening 11, so that when the sealing door 12 is opened, the manipulator 31 on the assembly seat 3 can perform construction work on the corresponding part of the construction work surface. The manipulator 31 can be, for example, a welding torch, a cutting torch, an electric rotary torch, a contact head, etc., which can be remotely controlled, that is, the manipulator 31 can be a programmable robot that can obtain images inside the underwater operation sealed cabin and feed them back to the relevant host computer (or control component) of the control personnel for control.

[0028] The cover body 1 includes a frame 13 and a waterproof plate 14 laid on the inner side and / or outer side of the frame 13. The frame 13 can be formed by splicing and assembling multiple main beams and auxiliary beams (for example, by welding) to meet the pressure resistance requirements of the underwater environment. The waterproof plate 14 includes a corrosion-resistant rubber layer 142 and canvas layers 141 on both sides of the corrosion-resistant rubber layer 142. The corrosion-resistant rubber layer 142 is embedded with a steel mesh 143, wherein the canvas layer 141 can protect the corrosion-resistant rubber layer 142 from mechanical damage, and the provision of the steel mesh 143 is mainly to enhance the strength of the waterproof plate 14. The corrosion-resistant rubber layer 142 serves as the core waterproof component of the waterproof plate 14.
