Description

Technical Field

[0001] The invention relates to a ship buoy clamping device, in particular to a high-precision, multi-directional ship buoy clamping device. Background Art

[0002] Currently, inspecting and maintaining marine aids to navigation is a relatively dangerous process. Most commonly used aid clamping devices require manual operation when the vessel approaches the aid. This poses safety concerns for operators in harsh sea conditions. Furthermore, the vessel's hull moves in six degrees of freedom with the movement of waves, which adversely affects the hooking process. This is especially difficult to perform in high waves and low temperatures, significantly reducing the efficiency of aid inspection and maintenance.

[0003] Conventional navigation mark clamping devices are installed at the bow of the ship. The clamping device holds the navigation mark, which is rigidly connected to the hull. A flipping device allows the mark to be flipped onto the bow deck for further inspection and maintenance. The layout of the navigation mark clamping device places high demands on the deck layout and requires appropriate modifications to the bowline design. This type of navigation mark clamping device can only hold conventional navigation marks. Conventional navigation marks have cylindrical buoys, while ice-age navigation marks have conical buoys. Due to the different buoy shapes, conventional clamping devices are unable to securely hold ice-age navigation marks, further preventing inspection, maintenance, and repair of navigation marks.

[0004] This navigation mark clamping device is installed at the bow of a catamaran. The catamaran's larger deck area facilitates placement of the navigation mark clamping device on the bow deck, eliminating the need to modify the bow's hull lines. The catamaran also offers excellent stability, allowing navigation mark personnel to inspect and repair the mark more smoothly when sea conditions are severe. When the catamaran's bow docks at the mark, the navigation mark clamping device automatically and accurately grasps the mark, efficiently and precisely holding marks of various shapes. This device has a wide range of applications, high operational efficiency, excellent safety, reliability, and is simple and easy to operate. Summary of the Invention

[0005] Purpose of the invention: The technical problem to be solved by the present invention is to be able to clamp navigation marks of different shapes and different buoy diameters.

[0006] Through the design of a catamaran, a base reinforcement plate, a rotating base, a first clamping arm, a second clamping arm, a hydraulic transmission device, a navigation mark righting turntable, a flexible clamping device, a navigation mark shape recognition sensor, a flexible clamping claw, a second hydraulic transmission device, a ship-borne information processor, and a clamping tray, the problems of low efficiency in navigation mark inspection and maintenance, cumbersome operations for navigation mark workers, and high risks for navigation mark workers at work are solved.

[0007] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0008] The present invention is a ship buoy clamping device, comprising a clamping arm device and a flexible clamping device, a base reinforcement plate installed in the center of the deck of a catamaran, a rotating base vertically installed on the base reinforcement plate, a first clamping arm bottom plate installed on the rotating base, a second clamping arm installed on the other end of the first clamping arm through hydraulic transmission, a navigation mark righting device installed on the other end of the second clamping arm, one end of the navigation mark righting device is fixedly connected to a clamping tray, a flexible clamping device is installed on the other side of the clamping tray, a flexible clamping device and a navigation mark shape recognition sensor are installed on the inner side of the clamping claw, and a sensor is also installed on the outer side of the clamping claw, and the navigation mark is clamped by rotating the clamping claw.

[0009] The beacon shape recognition sensor identifies whether the beacon is a standard or ice beacon, using the onboard computer. If it is a standard beacon, the diameter of the beacon is further determined, and the flexible clamping device adjusts to the beacon's external shape. The clamping jaws retract to further stabilize the beacon and establish a rigid connection with the catamaran. If it is an ice beacon, the flexible clamping jaws adjust to the external shape of the beacon, securing the clamping device to the beacon.

[0010] One end of the chassis righting turntable is slidably connected to the clamping tray, and the other end is slidably connected to the second clamping arm. When the buoy is lifted, the buoy is rigidly connected to the clamping tray, and the buoy and the deck surface of the catamaran are perpendicular to each other. When the buoy worker moves from the deck to the buoy, the buoy worker can reach the buoy smoothly.

[0011] Compared with existing technologies, the advantages of the present invention are: the rotating base can expand the gripping range of the clamping device, the second clamping arm can raise and lower the navigation mark, and the flexible clamping device can clamp both ordinary navigation marks and ice-age navigation marks, as well as navigation marks with different diameters. The clamping device is firmly connected to the navigation mark, allowing navigation mark workers to climb on the navigation mark to inspect and repair it, reducing the labor intensity of navigation mark workers and ensuring their personal safety. The device also has high gripping efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of the present invention.

[0019] The present invention will be further described below with reference to specific examples. Those skilled in the art will appreciate that these examples are intended only to illustrate the present invention and are not intended to limit the scope of the present invention, and that modifications to various equivalent forms of the present invention fall within the scope defined by the appended claims.

[0020] The present invention provides Figure 1-4As shown, a specific embodiment of the present invention provides a ship buoy clamping device, wherein the catamaran (1) comprises: a catamaran hull (9) and a deck with a hole (10). The deck hole is located at the bow of the hull deck, between the catamaran hulls (9). After the clamping device clamps the navigation mark, the navigation mark can be placed at the position of the catamaran hole. Nut holes are also opened on the deck for fixing the base reinforcement plate. The mechanical arm clamping device (2) comprises a base reinforcement plate (5), a rotating base (6), a first clamping arm (11), a second clamping arm (12), a motor (7), a navigation mark straightening turntable (8), and a hydraulic transmission device (13). The rotating base is installed on the base reinforcement plate (5), which can clamp a wider range of navigation marks. The flexible clamping device includes a clamping tray (14), a clamping claw (15), a navigation mark shape recognition sensor (16), a pressure block (18), and a pressure block fixing plate (19). The flexible clamping device (3) is installed on the clamping tray (14). The pressure block fixing plate (19) is installed at one end of the inner side of the clamping tray (14). The pressure block fixing plate (19) is fixedly connected to the clamping claw, and the pressure block (18) extends from the surface of the clamping claw. The first clamping arm (11) and the second clamping arm (12) are connected by a hydraulic device. When the navigation mark shape recognition sensor (16) recognizes the navigation mark, the first clamping arm (11) and the second clamping arm (12) can be adjusted through the onboard information processor so that the navigation mark is within the range that the clamping claw can grasp. A pressure block fixing plate (19) is installed at the front end of the inner side of each of the two clamping jaws, and a navigation mark shape recognition sensor (16) is installed on the surface of the pressure block fixing plate (19). The inner sides of the two clamping jaws are fixedly connected to the pressure block fixing plate (19), and a slidable pressure block is provided on the surface of the pressure block (18) extending out of the surface. A navigation mark shape recognition sensor (16) is also installed on the outer side of each of the two clamping jaws, and the clamping jaws are connected to the navigation mark tray pin.

[0021] When the catamaran (1) approaches the navigation mark, the first clamping arm (11) and the second clamping arm (12) are adjusted, and the angle is adjusted so that the clamping tray (14) of the clamping device contacts the navigation mark. The navigation mark shape recognition sensor (16) recognizes whether it is an ordinary navigation mark or an ice age navigation mark, and further adjusts the shape of the clamping surface of the flexible clamping device (3). The clamping claw is retracted so that the clamping device and the navigation mark become rigidly connected, completing the clamping process. The second clamping arm (12) is adjusted to lift the height of the navigation mark so that the navigation mark is perpendicular to the surface of the hull. The navigation mark is adjusted to a suitable height so that the navigation mark staff can safely climb onto the navigation mark and then inspect and repair the navigation mark.

[0022] The present invention has an ingenious design and a reasonable structure. The clamping range of the clamping device can be increased by rotating the base, the second clamping arm can lift the buoy, and the flexible clamping device can clamp ordinary buoys as well as icy buoys, as well as buoys with different diameters, so that the clamping device and the buoy are firmly connected together, and buoy workers can board the buoy to inspect and repair it, which reduces the labor intensity of the buoy workers and ensures personal safety. The clamping efficiency of this device is also high, and it can efficiently and safely clamp buoys of various shapes. It does not require buoy workers to directly participate in the lifting process of the buoy, and it can also adapt to relatively harsh sea conditions and effectively operate the buoy.

[0023] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention. Such modifications and variations are all within the scope defined by the appended claims.
