Description

Technical Field

[0001] This utility model relates to a trailing suction hopper dredger equipment technology, and more particularly to a marine buoy deployment and recovery device. Background Technology

[0002] Before the trailing suction hopper dredger begins its bow blowdown, a system is used to quickly connect and lock the marker buoy at the end of the mud transport pipeline to the cable on the dredger. Then, the buoy is hoisted and retrieved back onto the dredger to connect the mud transport pipeline to the bow blowdown device. After the bow blowdown is completed, a system is used to lower the marker buoy to the sea surface and then quickly disconnect it from the cable on the dredger to separate the mud transport pipeline from the dredger, making it easier for the dredger to access the sand extraction area.

[0003] Currently, there is no dedicated rapid deployment and retrieval system for marker buoys on trailing suction hopper dredgers. Existing technology relies on a combination of manual labor and a transport vessel. Crew members on the transport vessel retrieve the buoy and connect it to the cable shackle to achieve buoy retrieval, and then manually disconnect the buoy from the cable shackle to deploy it. This approach suffers from low safety and high costs.

[0004] In summary, the current problem is:

[0026] The specific embodiments of this utility model are further described below:

[0027] See Figures 1 to 7 This embodiment provides a marine buoy deployment and recovery device, which is used to realize the rapid deployment and recovery of buoy 1 on the sea surface.

[0028] See Figure 1 and Figure 2 The marine buoy deployment and recovery device of this embodiment includes a buoy 1, a main pod 2, and a dome plate 3.

[0029] See Figure 5 The float 1 is a device of the prior art. The float 1 is based on a float frame 11, and a number of spherical floats 12 are arranged on the circumferential part of the float frame 11 to form a complete float 1.

[0030] See Figure 4 The dome plate 3 is generally in the shape of a cross plate and is assembled at the top of the float 1.

[0031] See Figure 1 and Figure 2 The dome plate 3 is assembled on the top of the float 1. The assembly method is that the edge of the dome plate 3 is in contact with the top of the spherical float 12 of the float 1. Then, four clamping pieces 4 are used to fix the edge of the dome plate 3 to the top of the spherical float 12, thereby realizing the assembly of the two.

[0032] See Figure 6 It should be noted that the clamping member 4 is a prior art connecting component, which consists of two clamping plates combined with four bolt fasteners. A clamping hole is also provided between the two clamping plates to clamp the steel bars of the float frame 11.

[0033] See Figure 1 and Figure 2 An iron plate 31 is provided at the center of the dome plate 3, and a number of guide rods 5 are provided around the iron plate 31. These guide rods 5 are all tilted at a certain angle around the iron plate 31 in a direction away from the iron plate 31. All the guide rods 5 are combined together to form a shape similar to an upward-facing horn.

[0034] For ease of description, this arrangement is defined as the "downward guiding arrangement". That is, all the guiding rods 5 are arranged in a downward guiding arrangement around the iron plate 31. This arrangement is beneficial for guiding the main pod 2 to the iron plate 31 at the center of the dome plate 3.

[0035] It should be noted that the guide rod 5 is mounted on the dome plate 3 by an adjustable angle support 6 of the prior art. In this way, the angle of the guide rod 5 can be adjusted based on the dome plate 3, so as to adjust the angle of each guide rod 5, thereby forming the downward guide arrangement mentioned above.

[0036] See Figure 7 The adjustable angle support 6 mainly includes a sleeve 61 and a base 62. The sleeve 61 and the base 62 are assembled together by a prior art retractable bolt hinge mechanism 63. When the bolt in the retractable bolt hinge mechanism 63 is loosened, the sleeve 61 and the base 62 are movable, and the included angle between them can be adjusted. When the bolt in the retractable bolt hinge mechanism 63 is tightened, the sleeve 61 and the base 62 are clamped together, and the included angle between them is fixed. The base 62 of the adjustable angle support 6 is fixedly connected to the dome plate 3. When installing the guide rod 5, the lower end of the guide rod 5 is assembled together with the sleeve 61.

[0037] See Figure 3 An electromagnet 21 is installed at the bottom of the main pod 2. The electromagnet 21 is used to attract the iron plate 31 at the center of the dome plate 3. A camera 22 is installed on the side of the main pod 2. The lens of the camera 22 is facing the electromagnet 21. The camera 22 is used to observe whether the electromagnet 21 attracts or detaches from the iron plate 31 at the center of the dome plate 3.

[0038] A lifting ring 23 is provided on the top of the main pod 2 to facilitate the use of lifting equipment to lift the main pod 2.

[0039] An electrical control unit is installed inside the main pod 2. This unit is used to control the electromagnet 21 to start and stop, and to control the camera 22 to collect video.

[0040] In addition, the electronic control unit is also equipped with a wireless data transmission component (graphic and data transmission integrated radio). In this way, the electronic control unit can achieve wireless communication with a pre-prepared remote control terminal (graphic and data transmission remote control) through the wireless data transmission component. On the one hand, the remote control terminal can remotely control the electromagnet 21 to start and stop. On the other hand, the remote control terminal can acquire the video captured by the camera 22 and observe the situation of the electromagnet 21 attracting the iron sheet 31 in real time.

[0041] The method of use and working principle of the marine buoy deployment and recovery device of this embodiment are as follows:

[0042] When it is necessary to deploy buoy 1 on the sea surface, on the mother ship, the electromagnet 21 of the main pod 2 is attached to the iron plate 31 of the dome plate 3. The electromagnet 21 is activated by the remote control terminal, and the electromagnet 21 and the iron plate 31 are attracted together. The main pod 2 and buoy 1 are then combined into one. The main pod 2 is lifted to the sea surface by the hoisting equipment (winch) on the mother ship through the hoisting ring 23. The main pod 2 and buoy 1 float on the sea surface. Then, the electromagnet 21 is deactivated by the remote control terminal again, and the electromagnet 21 and the iron plate 31 are separated. That is, the main pod 2 and buoy 1 are separated, thus completing the deployment of buoy 1 on the sea surface.

[0043] When it is necessary to retrieve the buoy 1 from the sea surface to the mother ship, the hoisting equipment (winch) on the mother ship is used to hoist the main pod 2 to the buoy 1 floating on the sea surface via the hoisting ring 23. The hoisting equipment is controlled to align the main pod 2 with the buoy 1 below and slowly descend towards the iron plate 31 in the center of the dome plate 3. When the main pod 2 approaches the iron plate 31, under the guidance of numerous guide rods 5, the main pod 2 is guided to the iron plate 31 in the center of the dome plate 3 until the electromagnet 21 at the bottom of the main pod 2 sits on the iron plate 31. The video footage captured by the camera 22 is used to determine whether the electromagnet 21 is firmly seated on the iron plate 31. After confirming that the electromagnet 21 is firmly seated, the electromagnet 21 is activated by the remote control terminal on the mother ship. The electromagnet 21 and the iron plate 31 are attracted together, and the main pod 2 and the buoy 1 are combined into one. Then, the hoisting equipment is controlled to hoist the combined main pod 2 and the buoy 1 back to the mother ship, thus completing the entire retrieval process.

[0044] The marine buoy deployment and recovery device of this embodiment can conveniently and quickly deploy the buoy 1 on the sea surface or recover the buoy 1 from the sea surface.

[0045] In addition, this offshore buoy deployment and recovery device has the following advantages:

[0046] 1) In the marine buoy deployment and recovery device of this embodiment, the guide rods 5 arranged around the iron plate 31 are arranged in a downward guiding manner. In this way, the combination of these guide rods 5 has a guiding function. During the recovery of the buoy 1, the main pod 2 can be guided to the iron plate 31, so that the electromagnet 21 and the iron plate 31 can be quickly and accurately docked.

[0047] 2) In the marine buoy deployment and recovery device of this embodiment, the camera 22 can transmit the movement image of the buoy 1 below the main pod 2 in real time, which helps the construction personnel to quickly determine whether the main pod 2 can be successfully guided to the iron plate 31 through the guide rod 5 to complete the docking, and adjust and attempt a second docking in time if the docking cannot be successfully completed.

[0048] 3) In the marine buoy deployment and recovery device of this embodiment, the mechanical structure has been greatly simplified, significantly reducing the complexity of components and the failure rate, and has high operational reliability under high sea state conditions.

[0049] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
