Description

Technical Field

[0001] This utility model relates to the field of underwater operation equipment technology, specifically, to an underwater magnetic adsorption sealed operation cabin. Background Technology

[0002] To ensure a tight fit between the underwater work cabin and the target steel structure during underwater operations, an adsorption mechanism is typically installed around the front of the underwater work cabin and sealed with sealing rings around the perimeter to provide a completely sealed environment inside the cabin. This facilitates the drainage of water accumulated inside the cabin, thereby creating a dry working environment.

[0003] Traditional adsorption sealing methods rely on magnetic strips inside the slots at the front of the cabin to achieve adsorption and sealing. However, the sealing effect is poor if the surface of the structure is uneven. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an underwater magnetic adsorption sealing work chamber that can be adsorbed onto uneven surfaces and has a good sealing effect.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an underwater magnetic adsorption sealing work chamber, including an underwater work chamber, a magnetic opener / closer, a hydraulic device, and a sealing ring. Multiple magnetic openers are arranged around the perimeter of the underwater work chamber, and a hydraulic device is provided next to each magnetic opener / closer. A sealing ring is provided around the contact surface between the underwater work chamber and the target steel structure.

[0006] Preferably, the magnetic opener / closer is composed of a fixed magnet and a rotatable magnet, with the fixed magnet enclosing the rotatable magnet, and the magnetic force of the magnetic opener / closer can be adjusted by rotating the magnetic poles of the rotatable magnet.

[0007] Preferably, the sealing ring is a three-layer hollow sealing ring.

[0008] Preferably, the underwater work cabin is equipped with a drainage device for discharging water outwards.

[0009] The following beneficial effects can be obtained by adopting the technical solution of this utility model:

[0010] Once the underwater work capsule approaches the designed position on the surface of the target steel structure, the magnetic opening and closing device is activated. The magnetic force of the built-in permanent magnet is adjusted to the designed value, causing the magnetic opening and closing device to adhere to the steel structure surface and providing pre-tightening force for sealing between the capsule and the structure. Then, by adjusting the accompanying hydraulic device, the sealing ring is compressed and deformed, resulting in a tighter fit between the capsule and the target steel structure, achieving an effective seal.

[0011] This device uses the magnetic force of permanent magnets to attract the underwater work pod to the target steel structure, providing a pre-tightening force for sealing the pod and structure. By adjusting the accompanying hydraulic mechanism, the sealing ring undergoes compression deformation under the combined action of hydrostatic pressure and magnetic attraction, resulting in a tighter fit between the sealing ring and the structure's surface. This gradually establishes stable contact, creating a sealed environment. Compared to traditional methods, this device offers better attraction due to the stronger magnetic force of the built-in permanent magnets; a better sealing effect due to the three-layer hollow seal design of the sealing ring, which allows for greater deformation under the same force; and a larger contact area, preventing damage from excessive compression of the sealing ring, thus improving reliability and durability.

[0019] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part.

[0020] like Figure 1As shown, this underwater magnetic adsorption sealing work chamber includes an underwater work chamber 1, magnetic openers 3, hydraulic devices 4, and sealing rings 5. Multiple magnetic openers 3 are arranged around the perimeter of the underwater work chamber 1, and each magnetic opener 3 is equipped with a hydraulic device 4. A sealing ring 5 is arranged around the contact surface between the underwater work chamber 1 and the target steel structure 2. The magnetic opener 3 is composed of a fixed magnet and a rotatable magnet; the fixed magnet encloses the rotatable magnet, and rotating the magnetic poles of the rotatable magnet adjusts the magnetic force of the magnetic opener. The sealing ring 5 is a three-layer hollow sealing ring, providing a good sealing effect. A drainage device is installed on the underwater work chamber 1 for draining water. After the underwater work chamber 1 is pressed tightly against the target steel structure 2, the drainage device is opened to drain water. Due to the pressure difference between the inside and outside, the water pressure presses the underwater work chamber 1 firmly against the target steel structure 2, allowing underwater workers to be placed inside the underwater work chamber 1 to work on the surface of the target steel structure.

[0021] like Figure 1-5 As shown, the implementation method of this work cabin includes the following steps:

[0022] (1) Magnetic opener 3, matching hydraulic device 4 and sealing ring 5 are arranged around the front end of the underwater work cabin 1, and are in good condition;

[0023] (2) The underwater work cabin 1 is positioned close to the target steel structure 2 at the designed location;

[0024] (3) When the magnetic opener 3 is opened, the magnetic force of the permanent magnet reaches the maximum design value, and the magnetic opener 3 is attracted to the surface of the target steel structure 2.

[0025] (4) Adjust the matching hydraulic device 4, and the underwater work cabin 1 continuously approaches the surface of the target steel structure 2;

[0026] (5) Under the combined action of hydrostatic pressure and magnetic attraction, the sealing ring 5 undergoes compression deformation, and a stable contact is gradually formed between the sealing ring 5 and the target steel structure 2, creating a sealing environment;

[0027] (6) The underwater work cabin 1 opens the drainage device to carry out underwater drainage operations. After the water is drained, the staff can carry out work in the underwater work cabin 1.

[0028] (7) After the operation is completed, adjust the hydraulic device 4 that is matched with the magnet and loosen the sealing ring 5;

[0029] (8) Close the magnetic opener 3 to release the magnetic attraction and separate the underwater work cabin 1 from the target steel structure 2;

[0030] (9) Recover the underwater work cabin 1.

[0031] After the underwater work capsule 1 approaches the designed position on the surface of the target steel structure, the magnetic opener 3 is opened, and the magnetic force of the built-in permanent magnet is adjusted to the designed value. The generated magnetic force causes the magnetic opener 3 to adhere to the surface of the steel structure and provides a pre-tightening force for sealing between the capsule and the structure. Then, by adjusting the matching hydraulic device 4, the sealing ring 5 is compressed and deformed, making the capsule fit more tightly with the target steel structure 2, achieving an effective seal.

[0032] This device uses the magnetic force of a permanent magnet to attract the underwater work chamber 1 to the target steel structure 2, providing a pre-tightening force for sealing the chamber and structure. Then, by adjusting the matching hydraulic mechanism, the sealing ring 5 undergoes compression deformation under the combined action of hydrostatic pressure and magnetic attraction, resulting in a tighter fit between the sealing ring 5 and the structure surface. A stable contact is gradually formed between the two, creating a sealed environment. Compared to traditional methods, this device offers better adsorption due to the stronger magnetic force of the built-in permanent magnet; greater deformation under the same force due to the three-layer hollow seal of the sealing ring 5; and a larger contact area, preventing damage from excessive compression of the sealing ring 5, thus improving reliability and durability.
