Description
Technical Field
[0001] The utility model relates to the technical field of ships, in particular to a displacement catamaran. Background Art
[0002] Displacement catamarans have broad application prospects due to their advantages such as spacious decks and low resistance when sailing at high speeds. However, due to their large lateral stability, they are prone to produce combined longitudinal and transverse harmonic roll motions when sailing in large waves, making passengers feel uncomfortable. In order to reduce the longitudinal and transverse harmonic roll motions of catamarans, anti-roll devices are usually installed on catamarans.
[0003] When a ship is in use, its engine will sink into the ocean and the propeller of the generator will be entangled with seaweed or aquatic plants in the ocean, requiring manual underwater cleaning of the propeller. During the manual cleaning process, there is no need to accurately cut foreign objects or aquatic plants, which increases the difficulty of propeller cleaning. In addition, when the hull is in operation, the height of the propeller is at a standard height, and it is difficult to dynamically adjust and control the height of the propeller according to the depth of the ocean or inland river.

[0024] In this embodiment, the positioning mechanism 4 includes a control box 2, a control shaft 3, a vertical force arm 9, a screw 10 and a lifting seat 11. The control box 2 is arranged directly above the shipboard 1, and the control shaft 3 is arranged on one side of the control box 2. The screw 10 is arranged on one side of the control shaft 3. The lifting seat 11 is connected to the outer side of the screw 10, and a hydraulic cylinder 12 is arranged below the lifting seat 11. The screw 10 is arranged inside the control box 2, and the position of the hydraulic cylinder 12 inside the control box 2 is adjusted and controlled by the screw 10.
[0025] In this embodiment, the lifting mechanism 8 includes a hydraulic cylinder 12, a block seat 13, a vertical guide rod 14, an external slot 15 and a fastener 16. The hydraulic cylinder 12 is arranged inside the control box 2, and the output end of the hydraulic cylinder 12 is connected to the block seat 13. The "L"-shaped vertical guide rod 14 is symmetrically arranged inside the control box 2. The "L"-shaped vertical guide rod 14 is penetrated and connected with a vertical force arm 9. The top of the vertical force arm 9 is provided with an external slot 15. The outer side of the vertical force arm 9 is rectangularly distributed with fasteners 16, and the internal setting of the control box 2 is positioned by the vertical guide rod 14.
[0026] In this embodiment, the hydraulic cylinder 12 is connected to the outer side of the external slot 15 via the block seat 13 at the output end, and the device is displaced via the block seat 13, thereby improving the flexibility of device adjustment and control.
[0027] In this embodiment, the vertical force arm 9 is connected to the control box 2 via a fastener 16 that penetrates the outside. By providing multiple groups of fasteners 16, the control box 2 and the vertical force arm 9 are positioned laterally to prevent the vertical force arm 9 from tilting.
[0028] In this embodiment, the propeller component 5 is connected through the outer side of the vertical lever arm 9 , and the propeller component 5 is positioned by the vertical lever arm 9 to complete the vertical lifting and adjustment of the propeller component 5 .
[0029] This type of displacement catamaran, when put into practical use, includes the following work:
[0030] Step 1: The operator first symmetrically arranges the transverse truss beam 7 just below the shipboard 1, and selects a single hull 6 of corresponding size, and connects the single hull 6 with the transverse truss beam 7. The operator holds the control shaft 3, drives the lead screw 10 to rotate through the control shaft 3, and drives the lifting seat 11 and the hydraulic cylinder 12 to slide laterally through the lead screw 10, so that the output end block seat 13 of the hydraulic cylinder 12 is engaged with the outer card slot 15, and the vertical force arm 9 and the propeller component 5 are vertically lowered by the hydraulic cylinder 12, and the height of the propeller component 5 is adjusted, and the fastener 16 is inserted into the outside of the control box 2;

The operator opens the propeller component 5, and pushes the ship board 1 and the single hull 6 through the propeller component 5, and uses the ship board 1 and the single hull 6 to transfer or work on the equipment;
[0032] Step 3: When the operator needs to clean one of the propeller components 5, the operator connects the block seat 13 at the output end of the hydraulic cylinder 12 with the external card slot 15, and then positions the vertical arm 9, and disassembles and separates the fastener 16 at the connection between the vertical arm 9 and the control box 2. When the ship needs to be maintained or repaired, the operator drives the ship to the vicinity of the dock through the propeller component 5;
[0033] Step 4: Loosen the connection between the fastener 16 and the vertical lever arm 9. The operator turns on the hydraulic cylinder 12, and drives the block seat 13 and the vertical lever arm 9 to perform vertical lifting and lowering through the hydraulic cylinder 12. The propeller component 5 is driven to vertically rise through the vertical lever arm 9, and then the vertical lever arm 9 and the propeller component 5 are extracted from the sea water or river water. The operator cleans the fishing nets or aquatic plants wrapped around the surface of the propeller component 5, and then completes the suspended cleaning or drying of the propeller component 5.
[0034] Therefore, the embodiments disclosed above are only illustrative in all aspects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
