An underwater equipment protection cover plate support structure

Abstract

The application discloses an underwater equipment protection cover plate supporting structure which is used for supporting a cover plate for protecting underwater equipment and mainly comprises a base, a locking push plate, a piston and a gas valve. During installation, the piston is pushed to compress gas by using the dead weight of the cover plate, and the locking push plate is pushed by the compressed gas to fix the supporting legs of the cover plate. The underwater equipment protection cover plate supporting structure has underwater installation automatic centering function and automatic locking function, and does not need to be operated by a diver, so that installation operation is simple.

Description

Technical Field

[0001] This invention relates to a support structure for a protective cover plate for underwater equipment, specifically a support structure for a cover plate used to protect underwater equipment. Background Technology

[0002] As underwater engineering continues to develop, the protection of underwater equipment has become an increasingly important research focus. Underwater equipment is frequently threatened by falling objects, and using protective covers is an effective measure to address this threat. Currently, a common practice is to install protective covers on the underwater foundation structure after it has been completed.

[0003] Underwater installation is a major challenge in current marine engineering. Currently, it typically employs lifting equipment and diver assistance. However, problems such as low underwater visibility and limited operating space for divers frequently arise during operations, leading to difficulties and high costs in complex environments. Therefore, simplifying the installation process and reducing costs through the rational design of underwater installation structures is the preferred solution to improve the current situation. Summary of the Invention

[0004] To address the challenges and high costs associated with installing underwater cover plates, this invention proposes a support structure for underwater equipment protective cover plates. This structure eliminates the need for divers and possesses autonomous centering and locking capabilities, significantly reducing installation difficulty and costs.

[0005] The solution adopted by this invention to solve its technical problem is as follows: This invention mainly consists of a base, a piston, a locking push plate, and an air valve. The base is designed with a flared opening at the top, which helps to center the cover plate support leg during installation. When not installed, the air valve at the bottom of the base is closed by a spring, and the piston and the base cylinder wall form a sealed space filled with compressed air. During the installation and insertion of the cover plate support leg, the piston is pushed down. When the piston moves to the bottom of the base, it opens the air valve, and the high-pressure gas pushes the locking push plate to lock the cover plate support leg.

[0006] The beneficial effects of this invention are: it does not require a diver to operate during installation, has autonomous centering and locking capabilities, which simplifies installation operations and reduces installation costs. Attached Figure Description

[0013] Depend on Figure 1 , 2 As shown in Figures 3, 4, and 5, this invention comprises a cover plate support leg 1, a base 2, a locking push plate 3, a piston 4, and a valve 5. The upper part of the base 2 has a flared centering opening 21, below which is a locking plate groove 22. The locking plate groove 22 is crescent-shaped along the inner side of the base 2 and has two cylindrical grooves. The shape and size of the locking plate groove 22 are adapted to the locking push plate 3. The lower part of the base 2 has a cylindrical groove adapted to the valve 5, and below it is a space communicating with the flow channel 23. The bottom of the base 2 has a cylindrical groove adapted to the spring 6. The flow channel 23 extends to communicate with the air pressure chamber 24. The locking push plate 3 includes a push plate 31 and a push rod 32, and the push rod 32 is designed with a sealing ring groove 33. There is a push rod 41 at the center below the piston 4. It is a cylindrical structure with a hole in the cylinder wall, so that compressed air on the outside of the push rod 41 can enter the inside of its cylindrical structure and then enter the flow channel 23 through the "T" shaped channel inside the air valve 5.

[0014] Depend on Figure 1 , 2 As shown in Figures 4 and 5, with the protective cover of the underwater equipment not installed, piston 4 is coaxially assembled with base 2, positioned below push plate 31. Piston 4 is sealed by sealing ring 7 in sealing ring groove 42, forming a sealed space with base 2, filled with compressed gas. A valve 5 at the bottom of the sealed space provides further sealing, held in place by spring 6. Below valve 5 is flow channel 23, filled with compressed gas. Flow channel 23 connects to pressure chamber 24, which is sealed by sealing ring 8 in sealing ring groove 33 on push rod 32. Locking push plate 3 is positioned in locking plate groove 22.

[0015] Depend on Figure 2 , 3As shown in Figures 4 and 5, during installation, the cover plate support leg 1 is inserted after being aligned through the centering port 21, pushing the piston 4 downward. During this process, the compressed gas below the piston 4 continues to be compressed. When the piston moves to the bottom of the base 2, the push rod 41 pushes the air valve 5, compressing the spring 6. The compressed gas below the piston 4 enters the flow channel 23 and then enters the air pressure chamber 24, forming high pressure in the air pressure chamber 24. This pressure pushes the push rod 32, causing the push plate 31 to press against the cover plate support leg 1, thus fixing the cover plate support leg 1 in place by friction.
