[0015] Figure 2 This is a schematic diagram of the underwater buckle in the open state in an embodiment of this utility model;

[0016] Figure 3 This is a schematic diagram of the underwater buckle in the locked state according to an embodiment of the present invention. Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings. It should be noted that this embodiment is based on the present technical solution and provides detailed implementation methods and specific operation processes, but the protection scope of the present invention is not limited to this embodiment.

[0018] This embodiment provides a multibeam system deployment and recovery device for ships, such as... Figure 1 As shown, it includes an electric hoist 1, a transfer and release bracket 2, and a rotating rod 4; the transfer and release bracket 2 is fixed on the deck of the ship near the side of the ship;

[0019] The receiver / amplifier bracket 2 includes a fixed base 21, an upper and lower rotating shaft 22, and an adapter 23. The upper and lower rotating shaft 22 is axially rotatably mounted on the fixed base 21. One end of the adapter 23 is fixedly connected to the upper and lower rotating shaft 22, and the central axes of the adapter 23 and the upper and lower rotating shaft 22 are perpendicular to each other. The other end of the adapter 23 is connected to the electric hoist 1 and is driven to rotate up and down by the electric hoist 1. One end of the rotating rod 4 is rotatably connected to the adapter 23 and can rotate around the adapter 23. The other end of the rotating rod 4 is used to fix the multibeam system (not shown in the figure).

[0020] The retracted state of the rotating rod is as follows Figure 1 As shown, the rotating rod is currently in a horizontal position. When the multibeam system needs to be placed in the water for depth sounding operations, the multibeam system is fixed to the other end of the rotating rod 4, and then the rotating rod 4 is moved along... Figure 1 Rotate the rotating rod in direction B until it is horizontal. Then, start the electric hoist 1, which drives the adapter 23 along... Figure 1 Rotating direction A downwards by 90° will cause rotating rod 4, along with the multibeam system, to rotate downwards by 90° as well. At this point, rotating rod 4 is in a vertical position, and the multibeam system is lowered into the water, ready for depth sounding operations. When it is necessary to retract the multibeam system, electric hoist 1 drives adapter 23 to rotate upwards by 90°, and then rotating rod 90° back to a horizontal position. It should be noted that, in addition to electric hoists, other types of lifting devices can be used, as long as they can achieve the vertical rotation of the adapter.

[0021] In this embodiment, the transfer and receiving bracket 2 further includes an upright support column 24, the bottom of the fixing seat 21 is fixed to the upper end of the upright support column 24, and the lower end of the upright support column 24 is used to connect to the deck of the ship.

[0022] In this embodiment, the multibeam retraction and deployment device further includes a fixed bracket 3, which is fixed to the deck of the ship and located on the same side of the deck as the transfer and deployment bracket 2, and arranged side by side with the transfer and deployment bracket 2 in the horizontal direction. The fixed bracket 3 is provided with a rotating rod holder 31, which is used to detachably engage and fix the rotating rod 4. When the rotating rod 4 is retracted and in a horizontal state, it is engaged in the rotating rod holder, which helps to fix the rotating rod in the retracted state and ensures its stability on the ship.

[0023] In this embodiment, one end of the rotating rod 4 is provided with a rotating sleeve 41, which is coaxially sleeved on the outside of the adapter 23, and the central axes of the rotating rod 4 and the rotating sleeve 41 are perpendicular to each other.

[0024] In this embodiment, as Figure 2 As shown in Figure 3, the multibeam retraction and deployment device also includes an underwater latch 5. The underwater latch 5 is connected to the lower part of the ship's side near the transfer and deployment support 2 and corresponds to the position of the transfer and deployment support 2. It has a rotating rod receiving cavity 51, and one side of the underwater latch 5 is an opening 52. The rotating rod receiving cavity 51 is used to detachably engage the rotating rod 4. The rotating rod 4 can enter and exit the interior of the rotating rod receiving cavity 51 through the opening 52. When the rotating rod 4 is rotated down to a vertical position, the lower part of the rotating rod 4 is engaged in the rotating rod receiving cavity 51, which can restrict and stabilize the position of the rotating rod 4, resist the impact of water flow on the rotating rod 4, and maintain the stability of the multibeam system's working state.

[0025] Furthermore, in this embodiment, the underwater buckle 5 also includes a movable locking rod 53 and an insert rod 54. The movable locking rod 53 is located on one side of the underwater buckle 5 where the opening 52 is provided, corresponding to the opening 52. One end of the movable locking rod 53 is rotatably connected to one side of the underwater buckle 5 corresponding to the opening 52. The other side of the underwater buckle 5 corresponding to the opening 52 and the other end of the movable locking rod 53 are both provided with locking holes 55 that match the insert rod 54. The insert rod 54 can be inserted into the locking holes 55.

[0026] After the rotating rod 4 is inserted into the rotating rod receiving cavity 51, rotate the movable locking rod 53 until the locking hole at the other end of the movable locking rod 53 corresponds to the locking hole on the underwater buckle 5. Then, insert the insertion rod 54 into the locking holes on the movable locking rod and the underwater buckle to lock the movable locking rod 53. At this time, the movable locking rod 53 can prevent the rotating rod 4 from disengaging from the rotating rod receiving cavity 51, thereby further increasing the stability of the rotating rod and the multibeam system. The length of the insertion rod is determined according to actual needs, specifically allowing the operator to stand on the deck and operate the insertion rod by hand. The insertion rod can extend down to the position of the underwater buckle. The operator can first use the insertion rod to rotate the movable locking rod, and then insert the insertion rod downward into the locking hole to lock the movable locking rod. At this time, the upper end of the insertion rod can be fixed to the upper part of the rotating rod with rope, hook, etc. When it is necessary to retract the rotating rod, lift the insertion rod, unscrew the movable locking rod, and then retract the rotating rod. The underwater buckle works in conjunction with the receiver and transmitter bracket to form an upper and lower fixing structure for the rotating rod, enhancing the stability of the rotating rod and the multibeam system during operation.

[0027] Furthermore, in this embodiment, the underwater buckle 5 can be flipped up and down 90 degrees to connect to the ship's side. Thus, when not in use, the underwater buckle can be flipped upwards and retracted, without affecting the ship's normal navigation and berthing.

[0028] Specifically, the transfer and deployment support can be made of high-strength stainless steel to withstand the corrosiveness of the marine environment. The surface of the fixed support needs to be treated with an anti-slip coating to prevent the rotating rod from slipping during the ship's navigation.

[0029] When installing the transfer and launch support, a location with sufficient space that does not interfere with the normal operation of the vessel should be selected. During installation, a steel plate (1000*400*10mm (length*width*thickness)) can be welded onto the deck first as a base reinforcement. Then, a flange (300mm diameter, 20mm thickness) is welded onto the steel plate as the base of the transfer and launch support. Holes are drilled and tapped into the flange for detachable connection of the transfer and launch support. In this embodiment, the height of the transfer and launch support is 1100mm, the diameter of the upright support column is 200mm, and the fixed base is 350mm long and 350mm wide. In actual installation, the height of the transfer and launch support can be made approximately level with the ship's railings to ensure the safety of the operators.

[0030] The electric hoist can be installed above the transfer receiver bracket, or by welding lifting lugs to the hull. It should be noted that the rated load capacity of the electric hoist must meet the weight requirements of the rotating rod, with a certain safety margin. The control circuitry of the electric hoist must be waterproofed to prevent electrical malfunctions caused by seawater corrosion.

[0031] The fixed brackets are installed side-by-side on one side of the transfer and launch brackets, with a certain distance between them. When installing the fixed brackets, a 200mm diameter, 20mm thick flange can be welded to the deck as the base of the fixed bracket. The flange is drilled and tapped to allow for detachable connection of the fixed brackets. The fixed bracket is 1500mm high, the lower column has a diameter of 100mm, and the rotating rod holder weighs approximately 50kg.

[0032] Specifically, the underwater buckle is welded and installed on the outer side of the ship's hull, 300mm above the water surface, near the transfer and launch support. The underwater buckle is 200mm wide, 400mm long, and 100mm high, weighing approximately 15kg. The installation of the underwater buckle must consider the impact of water flow on the multibeam system to ensure its stability during operation. The material of the underwater buckle must have good corrosion resistance to withstand long-term immersion in seawater.

[0033] For those skilled in the art, various corresponding changes and modifications can be made based on the above technical solutions and concepts, and all such changes and modifications should be included within the protection scope of the claims of this utility model.
