Abstract
Description
Technical Field
[0001] The present invention relates to a support structure for a protective cover of an underwater device, specifically a support leg structure for supporting a cover plate that protects an underwater device. Background Art
[0002] With the great development of ocean engineering, more and more underwater projects have been started, and underwater engineering equipment is often threatened by falling objects or trawl nets in the water. Among the protective structures of underwater devices, it is common to use an independent protective cover plate structure for protection. The design of the support structure of the protective cover plate affects the installation cost, expenses, etc. of the protective cover plate, as well as the protection effect of the protective cover plate on the underwater device. Therefore, the design of the support structure of the protective cover plate is very important.
[0003] At present, the installation of structures in the complex underwater environment requires divers to assist in the operation, with a large amount of work and high installation costs. For waters with low visibility or deep-sea environments, the installation operation is challenged.
[0004] The present invention proposes a support structure for a protective cover of an underwater device. This structure has the characteristic of convenient installation, can be installed in a complex underwater environment, and does not require manual operation, which can reduce the operation cost of underwater installation. Summary of the Invention
[0005] To solve the problems of high installation cost and high operation difficulty in the complex underwater environment, the present invention proposes a support structure for a protective cover of an underwater device. This structure does not require manual operation for fixation and can be fixed by relying on the self-weight of the protective structure during the underwater installation process. At the same time, considering the space limitation of the basic structure design, the height of the support leg base located on the basic structure should not be too large when not installed. The present invention can automatically increase the height during the installation process to ensure sufficient stability for the upper protective structure.
[0006] The solution adopted by the present invention to solve its technical problems is: The present invention mainly consists of two parts, an upper structure and a base. The upper structure includes an inner cylinder of the upper structure, an outer cylinder of the upper structure, and a centering plate of the upper structure. The base includes an outer cylinder of the base, an inner cylinder of the base, and a base. The present invention has a certain automatic centering ability in design. Its opening is designed in a trumpet shape, and at the same time, the opening is recessed in the lower base. During the insertion process of the cover plate support leg, it will not be deformed due to collision. During the insertion process of the cover plate support leg, a sealed space will be formed inside the support structure, squeezing the seawater inside the space. The seawater will push the upper structure of the support structure to rise. The rising height of the upper structure helps to increase the stability of the support leg. The upper structure forms a lift for the cover plate support leg at the rising end position, which helps to increase the stability of the protective cover plate. At the same time, the inserted part of the cover plate support leg is allowed to be designed with a smaller diameter, which is beneficial for installation centering.
[0007] The beneficial effects of the present invention are as follows: This design has a certain centering ability. Compared with the conventional flared centering design, this design is not easily deformed during collisions, and the inserted part of the cover plate support leg is designed with a small diameter, which is beneficial for centering. The upward movement of the upper structure during installation helps to enhance the stability of the protection structure. At the same time, the lifting of the upper structure on the cover plate support leg can share part of the weight of the protection cover, solving the problem of strength weakening caused by the small diameter of the inserted part of the cover plate support leg. The design of the upper structure that can move upward mainly considers that in actual engineering, the longitudinal space at this position of the structure is limited, and the structure that can move upward can solve this problem.

[0011] By Figure 1 , 2As shown in the figure, the protection cover plate support structure mainly includes two parts: the upper structure and the base. The upper structure includes the inner cylinder 21 of the upper structure, the outer cylinder 22 of the upper structure, and the centering plate 23 of the upper structure. The inner cylinder 21 of the upper structure is a cylindrical structure with a sealing ring groove on its inner side, and is connected to the horn-shaped centering plate 23 of the upper structure on its upper side. The centering plate 23 of the upper structure is connected to the cylindrical outer cylinder 22 of the upper structure. There is an outer cylinder conduit 222 inside the outer cylinder 22 of the upper structure. The base includes an outer cylinder 31 of the base, an inner cylinder 32 of the base, a filter screen 33, and a base 34. The outer cylinder 31 of the base is a cylindrical structure with one end open, having a sealing ring groove on its inner side, with the same angle and conical angle as the centering plate 23 of the upper structure on its upper part, and is welded to the basic support structure of the underwater equipment protection cover plate on its lower part. The base 34 is a cylindrical load-bearing structure connected to the bottom of the outer cylinder 31 of the base, having two mutually perpendicular rectangular cross-section gaps along the radial direction, and this gap connects the upper space of the base 34 with the annular space inside the filter screen 33. The inner cylinder 32 of the base is a cylindrical structure with a shoulder structure on its inner side, having the same angle and conical angle as the centering plate 23 of the upper structure on its upper part, and is connected to the base 34 and the filter screen 33 on its lower part. The filter screen 33 is an annular mesh structure connecting the centering plate 23 of the upper structure and the outer cylinder 31 of the base. During assembly, the upper structure and the base are assembled axially. The outer cylinder 22 of the upper structure is inserted into the annular space between the outer cylinder 31 of the base and the inner cylinder 32 of the base, and the inner cylinder 21 of the upper structure is correspondingly inserted into the position of the shoulder structure inside the inner cylinder 32 of the base.
[0012] As shown by Figure 1 and 2 , the diameter of the insertion section 12 of the lower structure support leg of the cover plate support leg 11 is smaller than that of the cover plate support leg 11. During the installation process, the insertion section 12 of the support leg is inserted through the centering plate 23 of the upper structure. The lower part of the centering plate 23 of the upper structure is supported by the outer cylinder 31 of the base and the inner cylinder 32 of the base to prevent deformation caused by collision during the insertion of the insertion section 12 of the support leg. The insertion section 12 of the support leg is inserted to the position of the sealing ring groove 211, and a sealed space is formed below by relying on the sealing ring 4. The insertion section 12 of the support leg continues to be inserted downward. The seawater in the sealed space enters and promotes the upward movement of the outer cylinder 22 of the upper structure after being filtered by the filter screen 33 through the gap between the bases 34. At the same time, the seawater enters the gap position between the centering plate 23 of the upper structure and the inner cylinder 32 of the base through the outer cylinder conduit 222. The sealing ring groove 311 on the outer cylinder 31 of the base prevents seawater from leaking out between the outer cylinder 31 of the base and the outer cylinder 22 of the upper structure during the sliding process. During the continuous downward movement of the insertion section 12 of the support leg, the centering plate 23 of the upper structure contacts and presses the cover plate support leg 11. When the insertion section 12 of the support leg is inserted until it contacts the base 34, the installation process ends. The base bears the main weight of the protection cover plate, and the upper structure bears a small part of the weight of the protection cover plate, mainly playing a role in further stabilizing.
