Description

Technical Field

[0001] The present invention relates to a support structure for a protection cover plate of an underwater device, specifically a support structure for a cover plate used to protect an underwater device. Background Art

[0002] In the increasing applications of underwater devices, the protection of underwater devices has increasingly become a research focus, and it is relatively common to use an independent cover plate to protect underwater devices. However, the installation of the protection cover plate in a complex underwater environment has long been a difficult problem. Currently, underwater protection cover plates usually require divers to assist in the installation. However, due to the low visibility in the complex underwater environment and the limited operation space for divers, the underwater installation operation is complex and the installation cost is relatively high.

[0003] On the premise of meeting the support for the cover plate, a reasonable structural design of the support structure for the underwater device protection cover plate can reduce the complexity of the installation operation and the installation cost at the same time, which helps to promote the development of the offshore industry. Summary of the Invention

[0004] To solve the problems of complex underwater installation operations and high requirements for divers, the present invention proposes a support structure for a protection cover plate of an underwater device, which has the ability of self-centering and locking and does not require divers to operate.

[0005] The solution adopted by the present invention to solve its technical problems is: The present invention is composed of a skirt umbrella, a piston, a base, a locking buckle and a spring. The skirt umbrella is located at the lower part of the cover plate support leg and serves as a weight-bearing structure for the installed cover plate. Its umbrella-shaped design is conducive to centering installation. The upper structure of the piston can be assembled with the central position structure of the skirt umbrella, and at the same time, the upper structure of the piston is designed as a sphere, which is conducive to centering during the installation with the skirt umbrella. The piston is assembled in the base, and the space formed by the base and the piston is a sealed cavity filled with hydraulic oil. During the process of the skirt umbrella pushing the piston downward, the hydraulic oil pulls back the locking buckle and locks the skirt umbrella.

[0006] The beneficial effects of the present invention are: The present invention has the ability of self-centering and self-locking during the installation process, does not require divers to operate, can be installed in a complex underwater environment with low visibility, the installation process is simple, and the installation cost is relatively low.

Detailed implementation manners

[0012] As Figure 1 、 2 、3, and 4 show, the present invention mainly consists of a skirt umbrella 1, a piston 2, a locking buckle 3, a base 4, and a spring 5. The skirt umbrella 1 includes a bearing groove 11, and the main function of this structure is to fix the position with the piston 2 during the installation of the protection cover of the underwater device, and at the same time transfer the weight of the cover to the piston 2 by the skirt umbrella 1. The piston 2 is a cylindrical structure with a semi-circular end, and there is a cylindrical groove at the bottom that is adapted to the spring 5. The slideway 21 is a groove with a rectangular cross-section on the piston 2, which is arranged along the circumference of the piston 2, and the number is 4. The upper stop shoulder 44 and part of the structure of the base 4 above the sealing cavity 22 are located in the slideway 21, restricting the movement range of the piston 2. The locking buckle 3 includes a crescent-shaped locking ring 31 and a locking rod 32 with a hexagonal cross-section, and the number is 4, which are installed in the locking rod slideway 41. The lower part of the base 4 is welded to the basic structure of the underwater equipment, and the locking rod slideways 41 are evenly arranged on the upper part. The inside of the barrel wall 42 forms a cylindrical space, and there is a cylindrical groove adapted to the spring 5 below this space. The flow channel 43 passing through the bottom of the base 4 passes through this cylindrical groove.

[0013] As Figure 1 、 2 、3, and 4 show, the piston 2 and the base 4 are assembled coaxially. Considering requirements such as manufacturing and processing difficulties, the base 4 is separated into upper and lower structures at a certain position of the barrel wall 42 for separate manufacturing, and the piston 2 is separated into upper and lower structures at a certain position of the slideway 21 for separate manufacturing. During installation, first weld the lower structure of the base 4 including the flow channel 43 and a part of the barrel wall 42, then install the spring 5, then install the lower structure of the piston 2, then install the upper structure of the base 4 and weld it to the lower structure, then install the upper structure of the piston 2 and weld it to the lower structure, and finally install the locking buckle 3.

[0014] As Figure 1 、 3 show, the piston 2 can move up and down through the slideway 21. In the un-installed state, the piston 2 is held by the spring 5 and stuck at the upper stop shoulder 44 position. The locking rod 32 of the locking buckle 3 is placed in the locking rod slideway 41. The piston 2, the base 4, and the locking rod 32 form a sealing cavity 22, and the sealing cavity 22 is filled with hydraulic oil.

[0015] As Figure 1 、2 As shown in Figures 3 and 4, during the installation process, the skirt umbrella 1 located below the cover plate support leg moves downward. The piston 2 contacts the umbrella cover 12 and centers the position of the skirt umbrella 1. The locking rod 32 contacts the opening of the lock catch positioning groove 13 and adjusts the angle of the skirt umbrella 1. After centering, the upper part of the piston 2 enters the bearing groove 11. The skirt umbrella 1 pushes the piston 2 downward by relying on the weight of the cover plate. During the downward movement of the piston 2, the hydraulic oil in the sealing cavity 22 pulls back the lock catch 3. During the pulling-back process, the locking ring 31 latches the skirt umbrella 1 at the position of the lock catch positioning groove 13 to fix it. At the same time, the piston 2 compresses the spring 5, and the seawater in the cylinder wall 42 is discharged through the flow channel 43. When the piston 2 moves to the bottom end position, the installation is completed.
