[0001] The invention relates to the technical field of floating breakwaters, in particular to a quick connection device for breakwaters and a floating breakwater. Background Art

[0002] Floating breakwaters are a type of protective structure widely used in oceans and lakes. They have the function of dissipating waves and ensuring that the working waters have a sufficiently stable surface environment. They have broad application prospects in the fields of protecting deep-water harbors and docks, serving as temporary berthing docks for ships, protecting aquaculture, beaches, offshore construction sites, offshore military mobile docks, and as wave-breaking measures for maritime disaster prevention and emergency response.

[0003] In the prior art, the connection between the various breakwater segments is achieved through anchor chain connection or tugboat connection. However, both of these connection methods have obvious limitations in achieving quick connection: although the anchor chain connection is stable, the connection process is cumbersome and inefficient; the tugboat connection is affected by various factors such as weather and water flow, and it is difficult to ensure a fast and accurate connection. In summary, the existing connection methods have the problems of low connection efficiency and low freedom of movement at the connection nodes, which results in poor convenience of the floating breakwater and affects the wave-breaking effect of the breakwater.

[0042] The structure of the mounting seat 6 is as follows: it includes a seat body 601, and a receiving groove 602 is opened on the seat body 601, so that an upper opening 603 is formed at the top of the seat body 601 and a side opening 604 is formed at the side of the seat body 601; the receiving groove 602 is used to accommodate a limiting ball 903, and the limiting ball 903 enters the receiving groove 602 through the upper opening 603, and the side opening 604 is used to allow the connecting rod 902 to pass through.

[0043] The shape of the inner bottom wall of the receiving groove 602 corresponds to the shape of the limiting ball 903 .

[0044] A baffle plate 7 is mounted on the top of the seat body 601 , and the baffle plate 7 is used to cover the upper opening 603 .

[0045] A mounting plate 2 is installed at the bottom of the mounting seat 6, a square groove is provided on the side surface of the mounting plate 2, a telescopic support plate 3 is installed in the square groove, and a plurality of hydraulic rods 4 are installed on the top of the mounting plate 2, the output ends of the hydraulic rods 4 are simultaneously connected to the telescopic support plate 3, and the hydraulic rods 4 drive the telescopic support plate 3 to move in a straight line, so that the telescopic support plate 3 extends out of or retracts from the square groove.

[0046] The present invention also provides a floating breakwater, which includes at least two breakwater segments 1, and at least one of the above-mentioned connecting devices is cooperatively installed on the outer wall surface of a single breakwater segment 1.

[0047] At least one installation groove 10 is provided on the side wall surface of a single breakwater segment 1, and the installation groove 10 is used for installing a connecting device.

[0048] The mounting groove 10 is provided with a mounting seat 6 and a horizontal spring 8 of a corresponding connecting device.

[0049] A guide assembly 5 is installed on the breakwater, and the guide assembly 5 is used to guide the corresponding breakwater segments 1 to dock.

[0050] The guide assembly 5 includes a first guide rod 501 and a second guide rod 502 . A guide ball 503 is disposed at the end of the first guide rod 501 , and a conical guide cover 504 is disposed at the end of the second guide rod 502 .

[0051] The first guide rod 501 and the second guide rod 502 are both equipped with corresponding guide cylinders 505 .

[0052] The specific structure and functions of the present invention are as follows:

[0053] By providing a connecting device, each breakwater segment 1 can be quickly and stably connected, thereby realizing breakwater connection and effectively improving the installation and layout efficiency of the floating breakwater; in addition, by providing a mounting seat 6, it can be flexibly connected to the connecting seat 9, thereby improving the freedom of movement between the corresponding breakwater segments 1.

[0054] The connecting device of the present invention is installed on the side wall surface of the breakwater segment 1 through the installation groove 10; according to actual use requirements, the installation grooves 10 can be opened on multiple side wall surfaces of the same breakwater segment 1, so that the breakwater segment 1 can be connected to multiple other breakwater segments 1 at the same time; multiple installation grooves 10 can also be opened on the same side wall surface of the same breakwater segment 1, so as to improve the connection stability between the corresponding breakwater segments 1.

[0055] The connection devices arranged on one side wall surface of a single breakwater segment 1 correspond one to one with the connection devices arranged on the corresponding side wall surface of another breakwater segment 1 to be docked therewith.

[0056] The guide assembly 5 is installed on the breakwater. The guide assembly 5 is used to guide the corresponding breakwater segments 1 when docking. By making the guide ball 503 fully contact with the conical guide cover 504, it can limit the two breakwater segments 1, thereby reducing the impact of waves and improving the speed and accuracy of the subsequent connection device when docking. Specifically, the guide cylinder 505 used to cooperate with the first guide rod 501 is fixed on the side wall surface of one breakwater segment 1, and the guide cylinder 505 used to cooperate with the second guide rod 502 is fixed on the side wall surface of the other breakwater segment 1. When the two breakwater segments 1 are docked, the guide ball 503 and the guide cover 504 approach each other until the guide ball 503 completely enters the guide cover 504, thereby completing the movement guiding effect on the corresponding breakwater segment 1; in addition, in order to improve the guiding effect, such as Figure 9-10 As shown, multiple groups of guide assemblies 5 can be symmetrically arranged on the breakwater.

[0057] A through hole is provided on one side wall of a single guide cylinder 505, and a rear cover 506 is installed at the through hole. When the rear cover 506 is opened, the corresponding guide rod (including the first guide rod 501 and the second guide rod 502) can slide in the guide cylinder 505, so that the end of the guide rod can extend from the through hole, thereby separating the corresponding guide ball 503 from the corresponding guide cover 504, so as to release the limiting effect of the guide assembly 5 on the breakwater; when the rear cover 506 is closed, the rear cover 506 limits the corresponding guide rod and can limit its axial displacement, so as to ensure the docking stability between the corresponding guide ball 503 and the corresponding guide cover 504.

[0058] A single connecting device includes a mounting plate 2, a telescopic support plate 3, a hydraulic rod 4, a mounting seat 6, a baffle 7, a horizontal spring 8, and a connecting seat 9; wherein,

[0059] The mounting plate 2 is fixed on the outer wall surface of the corresponding breakwater segment 1 and is located below the corresponding mounting groove 10; a telescopic support plate 3 is installed on the mounting plate 2 through the cooperation of a hydraulic rod 4, and the telescopic support plate 3 can make a linear motion of extending or retracting under the action of the hydraulic rod 4, so that when the two connecting seats 9 are docked, the corresponding two telescopic support plates 3 can be extended to support the corresponding connecting seats 9, so that the corresponding connecting seats 9 can remain relatively horizontal during docking, thereby improving the connection efficiency and reducing the impact of waves; when the two connecting seats 9 are docked, the two telescopic support plates 3 retract to avoid interfering with the movement of the connecting seats 9, so as to improve the freedom of movement between the breakwater segments 1.

[0060] A mounting seat 6 is fixed on the top of the mounting plate 2, one end of the mounting seat 6 extends into the mounting groove 10, and the other end is located outside the mounting groove 10;

[0061] Several horizontally installed horizontal springs 8 are arranged on the top of the mounting seat 6. One end of a single horizontal spring 8 is fixed to the inner wall surface of the mounting groove 10, and the other end is fixed to the side wall surface of the baffle 7. In the present invention, the end of the horizontal spring 8 can be fixed by welding. The horizontal spring 8 provides thrust for the baffle 7, so that the baffle 7 can extend forward to cover the upper opening 603 of the mounting seat 6. The horizontal spring 8 is a compression spring.

[0062] like Figure 1-Figure 2 As shown, the mounting seat 6 includes a seat body 601, and a receiving groove 602 is provided on the seat body 601. The receiving groove 602 is a special-shaped groove with a cylindrical upper portion and a spherical lower portion. The receiving groove 602 forms an upper opening 603 at the top of the seat body 601 and a side opening 604 at the side. The top of the seat body 601 is also provided with symmetrically arranged limit blocks 605, and a single limit block 605 is L-shaped. The limit block 605 can limit the baffle 7 from continuing to move forward, and can also prevent the baffle 7 from moving upward;

[0063] The baffle 7 is made of a triangular thick plate, with the tip of the baffle 7 facing forward and the tail end (i.e. the thicker end) facing backward. When the tip of the baffle 7 is against the limit block 605, the tail end is still located in the installation groove 10 and can fill the gap between the top wall of the seat body 601 and the top wall of the installation groove 10, so that the installation groove 10 and the seat body 601 form a limit for the tail end of the baffle 7. With the limiting effect of the limit block 605 on the baffle 7, the baffle 7 can stably cover the upper opening 603 at this time, even if the limiting ball 903 in the accommodating groove 602 collides with the baffle 7, it will not cause the baffle 7 to shift.

[0064] The lower part of the receiving groove 602 is spherical so that the shape of the inner bottom wall of the receiving groove 602 corresponds to the shape of the limiting ball 903, so that the limiting ball 903 can rotate in the receiving groove 603, thereby realizing a flexible connection between the mounting seat 6 and the connecting seat 9, thereby improving the freedom of movement between the two breakwater sections 1.

[0065] The top end surface of the seat body 601 is also provided with a mounting hole, in which a retractable plate is mounted. When the connecting seat 9 is not matched with the mounting seat 6, the retractable plate extends to limit the baffle 7 so that the baffle 7 is completely received in the mounting groove 10; when the connecting seat 9 is matched with the mounting seat 6, the retractable plate retracts so that the baffle 7 can extend from the mounting groove 10 to cover the upper opening 603. The retractable plate can be realized by using a linear drive member in combination with a square thin plate.

[0066] like Figure 3-Figure 6As shown, the connecting seat 9 includes a housing 901, a connecting rod 902, a limiting ball 903, a gear 906, a rotating body 908, a baffle 909, a central axis 910, a paddle 911, and a protrusion 912; wherein,

[0067] A first cavity 904 and a second cavity 905 are provided inside the shell 901. An inspection window is provided on the top of the shell 901. An inspection cover 907 is installed at the inspection window. When the inspection cover 907 is opened, the conditions inside the first cavity 904 and the second cavity 905 can be directly observed through the inspection window, which is convenient for subsequent regular inspection and maintenance.

[0068] The first cavity 904 is provided with a gear 906, a baffle 919, a central axis 910 and a paddle 911, wherein the central axis 910 is rotatably installed inside the first cavity 904, and the central axis 910 can be specifically rotatably matched with the wall surface of the housing 901 through a bearing; the gear 906 is fixed at the top end of the central axis 901, and a baffle 909 is also fixed on the gear 906, and the baffle 909 is arc-shaped and is arranged close to the central axis 910, so that the baffle 909 and the central axis 910 can clamp the starting end of the paddle 911;

[0069] A notch is provided at the front end of the first cavity 904, and the notch is in the shape of a quarter cylinder. A protrusion 912 is provided on the outer wall surface of the shell 901 corresponding to the first cavity 904, and a concave arc surface is provided on the side wall surface of the protrusion 912, and the concave arc surface is a quarter arc surface. The concave arc is combined and connected with the notch to form a semi-cylindrical accommodating space, and a semi-cylindrical rotating body 908 is arranged in the accommodating space. The rotating body 908 can completely fill the accommodating space. The rotating body 908 and the shell 901 are rotatably matched, which can be specifically achieved by a bearing assembly;

[0070] The rotating body 908 and the terminal end of the paddle 911 may be fixed by welding.

[0071] The second cavity 905 is used to cooperate with the protrusion 912 of another connecting socket 9 .

[0072] The connecting rod 902 is used to connect the housing 901 and the limiting ball 903. The connecting rod 902 and the protrusion 903 are arranged on two opposite outer side walls of the housing 901; the limiting ball 903 is used to cooperate with the mounting seat 6 for installation; specifically,

[0073] The limiting ball 903 is placed into the accommodating groove 602 through the upper opening 603, and the side opening 604 provides movement space for the connecting rod 902 to prevent the connecting rod 902 from interfering with the movement of the limiting ball 903; the diameter of the limiting ball 903 is larger than the diameter of the connecting rod 902, and the opening distance of the side opening 604 is slightly larger than the diameter of the connecting rod 902 and smaller than the diameter of the limiting ball 903, so that the limiting ball 903 cannot escape from the side opening 604;

[0074] The horizontal spring 8 pushes the baffle 7 to extend so that the baffle 7 covers the upper opening 603 , thereby completing the assembly between the mounting seat 6 and the connecting seat 9 .

[0075] The working process of the present invention is as follows:

[0076] When a breakwater segment 1 is docked with another breakwater segment 1, the movement trajectories of the two breakwater segments 1 are guided by the guide assembly 5, and at the same time, the two breakwater segments 1 are docked with each other through the connecting devices on the two breakwater segments 1;

[0077] When one of the connection devices is docked with another corresponding connection device, the following steps are included:

[0078] First, the hydraulic rods 4 in the two connecting devices are extended at the same time, thereby driving the corresponding telescopic support plates 3 to extend from the square grooves of the mounting plate 2 to support the corresponding connecting seats 9;

[0079] When the two breakwater segments 1 are approaching each other, the protrusions 912 in the two connecting devices are respectively inserted into the corresponding second cavities 905, so that the protrusion 912 of one connecting device pushes the rotating body 908 in the other connecting device to rotate clockwise;

[0080] The two clockwise rotating bodies 908 respectively drive the gears 906 meshing therewith to rotate counterclockwise, and the two counterclockwise rotating gears 906 respectively drive the baffles 909 and the middle shaft 910 connected therewith to rotate counterclockwise, so that under the joint action of the rotating bodies 908, the baffles 909 and the middle shaft 910, the spiral paddles 911 are stretched and deformed, and the two paddles 911 store elastic potential energy correspondingly;

[0081] When the two protrusions 912 are fully inserted into the corresponding second cavities 905, the concave arc surfaces on the two protrusions 912 avoid the rotating body 908 and no longer apply external force to the corresponding rotating body 908. At this time, the two semi-cylindrical rotating bodies 908 are connected to form a complete cylinder, and the two quarter concave arc surfaces and the two quarter cylindrical notches are connected to form a complete cylindrical space. The cylinder can rotate in the cylindrical space, so that under the elastic potential energy of the two paddles 911, the corresponding gear 906 is driven to rotate in the opposite direction (clockwise), and the corresponding rotating body 908 is driven to rotate counterclockwise by the two clockwise rotating gears 906, so that the two rotating bodies 908 return to their original positions. At this time, the paddles 911 have a limiting effect on the rotating body 908 to prevent it from rotating again, and then the two rotating bodies 908 prevent the two protrusions 912 from escaping from the corresponding second cavities 905;

[0082] The docking process of other connecting devices with corresponding connecting devices is similar to the above process and will not be repeated here. When all the connecting devices are docked, the two breakwater sections 1 are docked to form a floating breakwater.

[0083] The above description is an explanation of the present invention, not a limitation of the present invention. The scope of the present invention is defined in the claims. Any form of modification may be made within the scope of protection of the present invention.
