Description

Technical Field

[0001] The utility model relates to the technical field of marine equipment, in particular to an unmanned boat recovery and launching device. Background Art

[0002] The deployment or recovery of unmanned boats requires the use of equipment on the ship. Currently, most people use a lifting device to directly suspend the cage to drop the unmanned boat. Although this method has a simple structure and is relatively convenient to use, it is only suitable for situations with slight winds and waves or no winds and waves. When encountering larger winds and waves, the ropes of the lifting device will shake, which will affect the speed of the operation at the least, and the unmanned boat will detach from the cage or collide with the hull of a large ship at the worst. There are certain safety hazards, and its use still has certain limitations. Utility Model Content

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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 ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the present invention.

[0027] In the description of the present invention, “plurality” means two or more, unless otherwise clearly defined.

[0028] Reference Figure 1-4 As shown, an unmanned boat recovery and delivery device comprises: a hanger 1, two sets of hoisting mechanisms 3 are provided on the hanger 1, each set of hoisting mechanisms 3 includes two lifting ropes, a total of four lifting ropes, and the four lifting ropes are respectively arranged at the four corners of the rectangular hanger 1. When the cage 2 is lifted, the stability is better, and it is not easy to cause the ropes to be entangled or rotated. In this way, the lifting ropes in the same set of hoisting mechanisms 3 are synchronized to control the height and tilt of the left and right sides of the cage 2. When the left and right counterweights of the unmanned boat are unbalanced, or the position of the unmanned boat is offset and tilted left and right after it is parked in the cage 2, it can be The left and right tilt angles of the cage 2 can be adjusted by adjusting the lifting speed of the two sets of winch mechanisms 3 so that the position of the unmanned boat in the cage 2 can be corrected. A lifting ring 11 is provided on the top of the hanger 1. The lifting ring 11 is used to connect the lifting device on the ship, such as a cantilever crane and other equipment. Two pulling rings 13 are also provided on the side of the hanger 1. A traction rope is connected to the pulling ring 13. The traction rope can help stabilize the heavy object and prevent it from swinging or tilting during the lifting process, thereby reducing the risk of accidents; the cage 2 is arranged below the hanger 1, and the cage 2 is connected to the lifting rope. An unmanned boat entrance is provided on the side of the cage 2 for entering or removing the unmanned boat.

[0029] The hoisting mechanism 3 includes a driving motor 31 and a rotating shaft 32 driven by the output end of the driving motor 31. Both ends of the rotating shaft 32 are connected to the hanger 1. A reel 33 is provided near both ends of the rotating shaft 32. Each lifting rope has a separate reel 33 for easy maintenance.

[0030] A guide wheel 12 is also provided on the top of the hanger 1 to support the lifting rope and prevent the lifting rope from rubbing against the edge of the hanger 1.

[0031] The cage 2 is provided with a limit rod 4 on the side of the unmanned boat entrance. When the unmanned boat enters the cage 2, the limit rod 4 rotates to a horizontal closed position to prevent the unmanned boat from falling out of the cage 2. The limit rod 4 can be controlled by a pull rope or by a motor. In this embodiment, pull rope control is preferred, as the structure is stable and the cost is low.

[0032] The bottom of the cage body 2 is provided with a support rod 5 for supporting the bottom of the unmanned boat. The support rod 5 is arranged on the left and right sides of the bottom of the cage body 2. The bottom structure of the unmanned boat is mostly V-shaped. By supporting both sides of the bottom, the support stability is better when it is lifted, and it is also convenient to remove the unmanned boat recovery and delivery device after the unmanned boat is parked on the deck.

[0033] The support rods 5 are arranged from one side of the unmanned boat entrance of the cage 2 to the opposite side, and their heights are set from high to low, so that the unmanned boat will tilt as a whole toward the side of the cage 2 away from the unmanned boat entrance after entering the cage 2, and it is not easy to fall out of the cage 2.

[0034] A plurality of floats 6 are provided on the side of the cage 2 near the bottom, so that the cage 2 is more stable when suspended on the water surface. The floats 6 can be float balls or rubber air bags. Floats are preferably used because the float balls can be shared with other equipment on the ship and are not easily damaged, while rubber air bags are easily punctured. The floats 6 can be installed or not according to actual conditions.

[0035] The working principle of this utility model:

[0036] 1. When encountering general wind and wave conditions, connect the hanger 1 to the lifting device on the ship, hang the pulling rope on the pulling ring 13, and the crew assists in pulling one end of the pulling rope to lift the unmanned boat recovery and deployment device to the predetermined position above the water surface. Fix the pulling rope on the hull deck or railing to prevent the hanger 1 from swinging violently or spinning. Control the hoisting mechanism 3 to lower the cage 2 to the water surface. At this time, the limit rod 4 is flipped upward to the open position, and the unmanned boat is parked in the cage 2. Flip the limit rod 4 to the horizontal closed position. 1. Control the winch mechanism 3 to lift the cage 2. When the cage 2 fits the hanger 1 and rises to its proper position, the crew uses the pulling rope to assist in pulling and control the lifting device to lift the unmanned boat recovery and delivery device onto the deck, thus completing the recovery work. 2. When there is no wind or wave, directly connect the hanger 1 to the lifting device on the ship, hang the pulling rope, and lower the unmanned boat recovery and delivery device as a whole to the water surface. There is no need to start the winch mechanism 3 to lower the cage 2 separately. 3. The unmanned boat delivery operation method is opposite to the recovery operation sequence.

[0037] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
