Description

Technical Field

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

[0002] Floating breakwaters are a type of protective structure widely used in oceans and lakes, dissipating waves and ensuring a sufficiently stable surface environment. They have broad application prospects in areas such as protecting deepwater harbors and docks, serving as temporary berthing areas for ships, protecting aquaculture operations, bathing beaches, offshore construction sites, military maneuvering docks, and as a wave-breaking measure for maritime disaster prevention and emergency response.

[0003] In existing technologies, breakwater segments are connected via anchor chains or tugboats. However, both methods have significant limitations in achieving rapid connections: anchor chain connections, while stable, are cumbersome and inefficient; tugboat connections are affected by various factors, such as weather and currents, making it difficult to ensure a fast and accurate connection. In summary, existing connection methods suffer from low connection efficiency and limited freedom of movement at the connection nodes, resulting in poor portability of floating breakwaters and impacting their wave-breaking effectiveness. Summary of the Invention

[0004] Based on this, it is necessary to provide a quick connection device for breakwaters and a floating breakwater to address the problems that traditional floating breakwaters are difficult to achieve fast and accurate connection between breakwater segments, have low connection efficiency, poor connection convenience, and low freedom of movement at connection nodes.

[0040] The specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0041] like Figures 1-10As shown, a quick connection device for a breakwater of the present invention includes a mounting seat 6, on which a connecting seat 9 is mounted. The breakwater connection is achieved by docking the connecting seat 9 of one connecting device with the connecting seat 9 of another connecting device. The structure of the connecting seat 9 is as follows: it includes a shell 901, the interior of the shell 901 is hollowed out to form a first cavity 904 and a second cavity 905 that are independent of each other. A central shaft 910 is rotatably mounted in the first cavity 904, a gear 906 is fixed to the end of the central shaft 910, and a baffle 909 is fixed to the bottom of the gear 906. A spirally wound paddle 911 is installed between the baffle 909 and the central axis 910. The starting end of the paddle 911 is stuck between the baffle 909 and the central axis 910, and the terminal end of the paddle 911 is fixed to the outer circumferential surface of the semi-cylindrical rotating body 908. The rotating body 908 is rotatably installed on the shell 901. The middle part of the outer circumferential surface of the rotating body 908 is provided with gear teeth distributed along the circumference. The rotating body 908 is engaged with the gear 906 through the gear teeth; the outer wall surface of the shell 901 is provided with a protrusion 912 extending outward, and the shape of the protrusion 912 is consistent with the shape of the second cavity 905. Correspondingly, the side wall of the protrusion 912 is provided with an inner concave arc surface, which corresponds to the outer circumferential surface of the rotating body 908, thereby providing an installation space for the rotating body 908; a connecting rod 902 is provided on the other side wall opposite to the shell 901, and a limiting ball 903 is provided at the end of the connecting rod 902. The connecting seat 9 is installed in conjunction with the mounting seat 6 through the limiting ball 903; when the connecting seat 9 of one connecting device is docked with the connecting seat 9 of another connecting device, the two protrusions 912 are respectively inserted into the corresponding second cavity 905, and the two protrusions 912 respectively push the corresponding rotating body 908 to rotate When the two rotators 908 are rotated, the corresponding gears 906 are driven to rotate respectively, thereby driving the corresponding blocking piece 909 and the central axis 910 to rotate at the same time through the gears 906, causing the paddle 911 to deform and generate elastic potential energy; after the two protrusions 912 are fully inserted into the corresponding second cavity 905, under the action of the elastic potential energy generated by the deformation of the paddle 911, the corresponding gears 906 are driven to rotate in the opposite direction, thereby driving the corresponding rotators 908 to rotate in the opposite direction through the gears 906 until they are reset, and then the rotators 908 prevent the corresponding protrusions 912 from escaping from the corresponding second cavity 905.

[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, thereby forming an upper opening 603 at the top of the seat body 601 and a side opening 604 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 accommodating groove 602 corresponds to the shape of the limiting ball 903 .

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

[0045] The bottom of the mounting seat 6 is cooperated with the mounting plate 2, and a square groove is provided on the side end surface of the mounting plate 2. The telescopic support plate 3 is cooperated with and installed in the square groove. Several hydraulic rods 4 are cooperated with and 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. The hydraulic rods 4 drive the telescopic support plate 3 to move linearly, thereby extending or retracting the telescopic support plate 3 from the square groove.

[0046] The present invention also provides a floating breakwater, which includes at least two breakwater segments 1. At least one of the above-mentioned connecting devices is installed on the outer wall surface of each 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 . The end of the first guide rod 501 is provided with a guide ball 503 , and the end of the second guide rod 502 is provided with a conical guide cover 504 .

[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 setting up a connecting device, the various breakwater segments 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 setting up 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 connecting devices arranged on one side wall of a single breakwater segment 1 correspond one to one with the connecting devices arranged on the corresponding side wall 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 they are docked. By making the guide ball 503 fully contact 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 devices 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 guidance of 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 in conjunction with 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, thereby ensuring 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 a hydraulic rod 4. Under the action of the hydraulic rod 4, the telescopic support plate 3 can make a linear movement of extension or retraction, 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 base 6 is fixed to the top of the mounting plate 2, one end of the mounting base 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, enabling the baffle 7 to 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 base 6 includes a base body 601, on which a receiving groove 602 is formed. 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 base body 601 and a side opening 604 at the side. The top of the base body 601 is also provided with symmetrically arranged limit blocks 605. 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, its tail end is still located in the installation groove 10 and can fill the gap between the top wall surface of the seat body 601 and the top wall surface inside 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. Cooperating 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 accommodating groove 602 is spherical so that the shape of the inner bottom wall of the accommodating groove 602 corresponds to the shape of the limiting ball 903, so that the limiting ball 903 can rotate in the accommodating groove 602, thereby realizing a flexible connection between the mounting seat 6 and the connecting seat 9, and improving the freedom of movement between the two breakwater sections 1.

[0065] The top end surface of the base body 601 is also provided with a mounting hole, into which a retractable plate is mounted. When the connecting base 9 is not engaged with the mounting base 6, the retractable plate extends to limit the baffle 7, allowing the baffle 7 to be completely retracted into the mounting groove 10. When the connecting base 9 is engaged with the mounting base 6, the retractable plate retracts, allowing the baffle 7 to extend from the mounting groove 10 to cover the upper opening 603. The retractable plate can be implemented by using a linear drive member in conjunction 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 blocking piece 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, and an inspection cover 907 is installed in conjunction with the inspection window. After 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] A gear 906, a baffle 919, a central shaft 910, and a paddle 911 are mounted within the first cavity 904. The central shaft 910 is rotatably mounted therein, and specifically, a bearing is used to achieve rotational coordination between the central shaft 910 and the wall of the housing 901. The gear 906 is fixed to the top end of the central shaft 910, and a baffle 909 is also fixed to the gear 906. The baffle 909 is arc-shaped and is positioned close to the central shaft 910, so that the baffle 909 and the central shaft 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 of the shell 901 corresponding to the first cavity 904. The side wall of the protrusion 912 is provided with a concave arc surface, which is a quarter arc surface. The concave arc is combined with the notch to form a semi-cylindrical accommodating space. 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 rotate in cooperation, which can be achieved by a bearing assembly.

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

[0071] The second cavity 905 is used to cooperate with the protrusion 912 of another connecting seat 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 912 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. The side opening 604 provides space for the connecting rod 902 to move, preventing 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. 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 docking is performed through the connecting devices on the two breakwater segments 1;

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

[0078] First, the hydraulic rods 4 in the two connecting devices extend simultaneously, 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 approach 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. The two counterclockwise rotating gears 906 respectively drive the baffles 909 and the central axis 910 connected thereto to rotate counterclockwise. As a result, under the joint action of the rotating bodies 908, the baffles 909 and the central axis 910, the spiral-shaped paddles 911 are stretched and deformed, thereby causing the two paddles 911 to store elastic potential energy.

[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. 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 action of the elastic potential energy of the two paddles 911, the corresponding gears 906 are driven to rotate in the opposite direction (clockwise). The two clockwise rotating gears 906 drive the corresponding rotating body 908 to rotate counterclockwise, 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, preventing 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 their 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 segments 1 are docked to form a floating breakwater.
