Description

Technical Field

[0001] The invention relates to the field of connection devices, and in particular to a floating breakwater rigid quick connection device with a self-locking function. Background Art

[0002] Floating breakwaters can provide wave and current reduction for offshore ranches and floating platform operation areas. Floating breakwaters are composed of multiple unit modules, which are connected at sea through connecting devices. The purpose of offshore connection is to solve the problems of offshore assembly engineering design and construction, offshore transportation, and engineering installation of floating breakwaters with complex configurations, large scales, and irregular layouts.

[0003] At present, the connection of domestic offshore floating breakwaters or light offshore structures only relies on flexible connection of mooring cables or rigid fixation of smaller modules near the coast. This connection method is only suitable for port operations or low sea conditions, and has high technical requirements for the number of auxiliary ships and operators. There is no technical solution to solve the problem of rapid docking of rapidly deployed floating breakwaters or light offshore structures under high sea conditions.

[0004] At present, there is a new research demand for the offshore rapid connection technology of light floating structures such as floating breakwaters. The technical demand for the offshore rapid connection of light floating structures such as floating breakwaters requires that multiple unit modules can be quickly connected and reduce the requirements for auxiliary ships and operators. In a complex marine environment, the motion state of each module of the floating breakwater is different. If a purely rigid connection is used, it cannot release the relative degrees of freedom between the modules, and it cannot withstand the end face load under complex sea conditions and cannot operate in the open sea; the connection end face load is too large, which can easily cause damage to the breakwater or the connection device; if a flexible connection is used, the connection process has high requirements for the operation of auxiliary ships and personnel, and the purpose of rapid docking cannot be achieved, and the project cost is high. Summary of the invention

[0005] In view of the deficiencies in the above-mentioned prior art, the present invention provides a rigid quick connection device for a floating breakwater with a self-locking function. While being able to meet the technical requirements for rapid connection at sea, it fully considers the freedom of the connection interface that can be released, thereby reducing the load force generated between the connection interfaces; it meets the requirements for rapid connection of rapidly deployed floating breakwaters under higher sea conditions.

[0006] In order to achieve the above-mentioned purpose, the present invention provides a rigid quick connection device for a floating breakwater with a self-locking function, comprising a ball joint structure, a connection device and a self-locking device; the connection device is rotatably connected to a first floating breakwater through the ball joint structure; the first end of the self-locking device is connected to a second floating breakwater, and the second end of the self-locking device cooperates with the connection device and can be connected to the connection device.

[0007] Preferably, the ball joint structure includes a connecting part and a spherical limit part connected to each other; the first floating breakwater forms a semicircular groove, a plurality of internal ribs are arranged in the semicircular groove, and a flat sealing plate is fixed to the outer periphery of the opening of the semicircular groove; the spherical limit part can rotate freely and is partially arranged in the semicircular groove with a gap; the flat sealing plate limits the spherical limit part.

[0008] Preferably, the spherical limiting member comprises a spherical limiting plate connected to the connecting member and an arc-shaped tail sealing plate; and the spherical limiting plate and the tail sealing plate are on the same spherical surface.

[0009] Preferably, the adjacent sides of the internal rib and the spherical stopper are arc-shaped and the curvature is consistent with the curvature of the spherical stopper plate.

[0010] Preferably, a steering rod is connected to the connecting member.

[0011] Preferably, the connecting device includes a connecting end plate, two first ear plates and a connecting shaft; the connecting end plate is fixedly connected to the end of the connecting member; the first ear plate is vertically fixed to both sides of the connecting end plate; the connecting shaft is rotatably connected between the two first ear plates; the two first ear plates respectively form a corresponding first positioning pin through hole.

[0012] Preferably, the self-locking device comprises an upper semicircular buckle plate, two lower semicircular buckle plates, two second ear plates and a positioning pin; the upper semicircular buckle plate and the lower semicircular buckle plate are arranged opposite to each other, and the first ends of the upper semicircular buckle plate and the lower semicircular buckle plate are rotatably connected between the two second ear plates through a pin shaft respectively; the upper semicircular buckle plate is arranged between the two lower semicircular buckle plates; the second ends of the upper semicircular buckle plate and the two lower semicircular buckle plates respectively form a second positioning pin through hole; the inner sides of the upper semicircular buckle plate and the two lower semicircular buckle plates respectively form a semicircular groove; the upper The inner protrusions of the first ends of the semicircular buckle plate and the two lower semicircular buckle plates form an inverse curvature parabola segment; when the connecting shaft is completely pushed into between the upper semicircular buckle plate and the two lower semicircular buckle plates, the second positioning pin through holes of the upper semicircular buckle plate and the lower semicircular buckle plate overlap, and the semicircular grooves of the upper semicircular buckle plate and the lower semicircular buckle plate cooperate to form a circle that matches the periphery of the connecting shaft, the second positioning pin through hole corresponds to the position of the first positioning pin through hole, and the positioning pin can be inserted into the second positioning pin through hole and the first positioning pin through hole.

[0013] The present invention adopts the above technical solution, so it has the following beneficial effects:

[0014] 1. The ball joint structure adopts a loose connection. The spherical limit plate and the semicircular groove are loosely matched. The spherical limit plate can rotate freely in the groove, which can fully release the freedom of marine structures such as floating breakwaters and greatly reduce the end surface load at the connection;

[0015] 2. The self-locking device consists of upper and lower semicircular buckle plates (with positioning pin holes), the second ear plate, and the pin shaft. It can self-lock with the impact of the connecting device. The self-locking device is a purely mechanical operation. The locking process does not require an additional power system or power system. The operation is simple and convenient.

[0016] 3. On the premise of meeting the technical indicators of rapid docking at sea, this connector reduces the need for auxiliary vessels and only requires a small number of personnel to complete the docking, greatly reducing the construction period and cost.

[0017] 4. The inner side of the upper and lower semicircular gussets of the self-locking device is composed of a semicircle with the same curvature as the connecting shaft and a parabola segment with an inverse curvature. The design of the inverse curvature parabola segment can transform the thrust of the connecting shaft during the movement into the power to close the upper and lower semicircular gussets, thereby realizing the self-locking function.

[0018] 5. It can be connected conveniently, reliably, quickly and safely. The connection system does not require major changes to multiple modules such as floating breakwaters. It can be installed on the main structure of multiple modules as an equipment appendage. Only a small number of people are needed to assist in the docking process to complete the quick connection. The ball joint structure can release the degree of freedom of the connection interface and reduce the load generated between the connection interfaces. BRIEF DESCRIPTION OF THE DRAWINGS
