Description
Technical Field
The utility model relates to a supporting structure for a protective cover plate of underwater equipment, in particular to a supporting leg installation supporting structure for a cover plate of the protective underwater equipment.
Background
With the continuous development of ocean engineering, the application of underwater equipment is more and more extensive, and the underwater equipment is arranged on the seabed and threatened by objects falling in water and trawling nets in the long-term working process, so that the underwater equipment protection structure is very important. At present, the design of installing a protective cover plate on an equipment foundation in foreign underwater engineering is common.
The underwater environment is complex, higher requirements are provided for installation, a diver or an underwater robot is generally used for carrying out auxiliary installation on underwater equipment at present, the installation operation difficulty and cost are higher, and the fixed operation of a protective cover plate supporting structure and a foundation structure provides higher requirements for the diver and the underwater robot.
Disclosure of Invention
In order to solve the problem that the underwater equipment protection cover plate is high in installation difficulty and large in installation cost, the longitudinal distance of the installation connecting position is limited, the underwater equipment protection cover plate supporting structure has certain automatic centering capacity, is small in size, does not need a diver to perform fixing operation, and is simple in installation and operation.
The solution adopted by the utility model to solve the technical problem is as follows: the utility model mainly comprises three parts, namely a base, a moving structure and a piston, wherein the base is fixed on an underwater equipment foundation structure, the moving structure is concentrically fixed in the base, and the piston is assembled in the base.
The top open position of base designs for tubaeform, is favorable to the centering installation of protection apron supporting leg, and open position and removal structure's design make to meet apron supporting leg collision non-deformable in the installation.
And hydraulic oil is filled in a sealed space formed by the piston, the base and the moving structure and a sealed space formed by the base and the moving structure. In the installation, during the protection apron supporting leg inserted the base, rely on the protection apron dead weight to promote the piston downwards, the piston passes through hydraulic oil extrusion moving structure rebound, increases protection apron stability.
The utility model has the beneficial effects that: the utility model has certain centering capacity, and the centering inlet position is not easy to collide and deform. The whole supporting structure is small in size, the protection cover plate is pushed by self weight in the installation process to move the structure to enhance the stability of the supporting legs of the protection cover plate, and the installation process does not need a diver to operate.
Drawings
FIG. 1 is a schematic view of the present invention prior to installation.
Fig. 2 is a schematic view of the present invention after installation.
The device comprises 11 cover plate supporting legs, 12 supporting leg inserting sections, 21, a base inlet, 22, a base inner barrel, 23, a base outer barrel, 24, a base, 25, a sealing ring groove, 31, a stabilizing barrel, 32, a push rod, 33, a flow guide pipe, 4, a piston, 41, a sealing ring groove, 5, a sealing ring, 6 and a sealing ring.
Detailed Description
As shown in fig. 1 and 2, the upper part of the cover support legs 11 is connected to the protective cover of the subsea equipment, which serves as a connecting and supporting structure for the protective cover to its foundation structure. The bottom base is used as a component of a foundation structure of the submarine equipment and comprises a base inlet 21, a base inner cylinder 22, a base outer cylinder 23, a base 24 and a seal ring groove 25. And a moving part matched with the base, which comprises a stabilizing cylinder 31, a push rod 32 and a guide pipe 33. In the position shown, the inner base cylinder 22 and the outer base cylinder 23 have a cylindrical space which is matched with the cylindrical push rods 32, the cylindrical space is uniformly distributed along the circumference, the number of the cylindrical space is 4, and the number of the corresponding push rods 32 is four; and at other positions, the base inner cylinder 22 and the base outer cylinder 23 are connected into a whole structure. During assembly, the other structural assemblies of the base except the base inlet 21 are welded with the base structure of the submarine equipment, then the moving part is assembled, the ejector rod 32 is inserted into the cylindrical space of the base, hydraulic oil is filled in the position, and then the base inlet 21 is welded with the base inner cylinder 22 and the base outer cylinder 23. Then, the inside of the base inner cylinder 22 is filled with hydraulic oil, and a passage corresponding to the cylindrical space of the fitting position of the jack 32 is provided around the base 24 so that the hydraulic oil can enter the cylindrical space from the inside of the base inner cylinder 22. After the base inner cylinder 22 is filled with hydraulic oil, the piston 4 is inserted into the base inner cylinder 22 so as to form a sealed space between the inside of the base inner cylinder 22 and the lift pin 32.
As shown in figures 1 and 2, in order to facilitate centering installation, a support leg insertion section 12 below a cover plate support leg 11 is designed to be a small-diameter structure, in the installation process, the support leg insertion section 12 is inserted into a base through a base inlet 21, a piston 4 is pushed to move downwards, hydraulic oil among the piston 4, a base inner cylinder 22 and an ejector rod 32 is extruded, the ejector rod 32 is pushed to move upwards, and a stabilizing cylinder 31 is driven to move upwards. During the insertion process, the seal ring 5 installed in the seal ring groove 41 seals the hydraulic oil, and the seal ring 6 in the seal ring groove 25 positioned on the base outer cylinder 23 and the base inlet 21 seals the hydraulic oil in the space formed by the base inlet 21, the base inner cylinder 22, the stabilizing cylinder 31 and the push rod 32, and the hydraulic oil in the sealed space is balanced by the guide pipe 33 during the upward movement of the moving structure. When the piston 4 is pushed to the bottom to contact with the base 24, the installation is finished, at this time, the protruding part of the cover plate supporting leg 11 above the supporting leg inserting section 12 contacts with the base inlet 21 and shares part of the weight of the protective cover plate, and the stabilizing cylinder 31 moves upwards to wrap the lower part of the cover plate supporting leg 11, so as to enhance the stability of the protective cover plate.
Compared with the existing method that different underwater equipment needs to be connected and locked by a diver or an underwater robot in the installation process, the underwater device has low butt joint operation difficulty and can be pulled up only in the vertical direction, and under the conditions that an underwater protective cover plate is impacted by falling objects, a fishing net is dragged, ocean current disturbance and the like, a supporting structure formed by a plurality of the underwater protective cover plates can be influenced by vertical downward force and other moments and can not be influenced by vertical upward force, so that additional locking is not needed, and the installation operation difficulty and the installation cost are reduced.
