DETAILED DESCRIPTION

[0024] The present invention is further described in detail below with reference to the accompanying drawings.

[0025] A catamaran unmanned boat with a deployment and recovery device, the boat body includes an upper shell, two plates and a connecting bridge. The two plates are fixedly connected by a connecting bridge, and the connecting bridge increases the deck area of ​​the unmanned boat, which is conducive to the arrangement of the mission load on the surface of the boat body. The boat body is divided into four compartments, including a bow cabin 1, an equipment cabin 2, a front cabin 3 and a rear cabin 4. The bow cabin, the equipment cabin, the front cabin and the rear cabin are arranged in sequence from the bow to the stern. The upper shell is mainly divided into three sections, including an upper shell equipment section 10, an upper shell hoisting section 11 and an upper shell cabin section 12. The upper shell equipment section, the upper shell hoisting section and the upper shell cabin section are arranged in sequence from the bow to the stern.

[0026] The boat shape is a deep V boat shape to reduce wave resistance. The bow and stern are equipped with wave-suppression strips and wave-suppression plates respectively. The wave-suppression strips at the bow are used to break waves, and the wave-suppression plates at the stern are used to suppress waves at the stern. The upper shell is set inward.

[0027] An operation room is provided at the top of the upper shell equipment section. The operation room is provided with a hatch 6. A mast 5 is provided on the top of the operation room. The mast is set inwardly, and the inward inclination direction of the mast is the same as the inward inclination direction of the upper shell. Optoelectronic equipment 13 and navigation radar equipment 14 are installed on the mast.

[0028] The center of gravity of the upper shell pod section coincides with the center of gravity of the hull. A single-point hoist 7 is provided on the top of the upper shell pod section, which is used to keep the hull in a horizontal suspension state when the hull is lifted. The single-point hoist includes a base 18 and a hook 19, wherein the single-point hoist is connected to the upper shell pod section by bolts, and the hook is divided into a movable part and a fixed part. The mother ship's cable guide is locked with the hook through the movable part, and the cable guide cannot automatically fall out of the hook, thereby ensuring safety during lifting operations.

[0029] An air inlet 16 is arranged on the side wall of the upper shell equipment section, and the air inlet is arranged inwardly. An exhaust port 15 is arranged on the side wall of the upper shell nacelle section. The air inlet and the exhaust port run through the equipment cabin to ensure normal ventilation of the equipment cabin.

[0030] The present invention further comprises mooring piles 8, which are installed at the four corners of the upper shell. It also comprises fenders 17, which are used to reduce the impact force generated by the collision between the unmanned boat and the dock or the ship. It also comprises two propellers 9, wherein the two propellers are respectively installed at the tail of the two sheets, and are used to propel the ship or to turn.

[0031] The main engine is installed in the rear cabin, the fuel tank is installed in the front cabin, and the equipment cabin is equipped with a generator, batteries, autonomous navigation equipment, environmental collection equipment and communication and navigation equipment.

[0032] According to the above-mentioned catamaran unmanned boat with a deployment and recovery device, a model is constructed and a catamaran unmanned boat is built to illustrate the effect of the present invention.

[0033] like Figure 1 and Figure 2 As shown, the hull of a catamaran unmanned boat with a deployment and recovery device of the present invention is mainly composed of an upper shell, two panels and a connecting bridge. The hull is divided into four compartments, including a bow cabin, an equipment cabin, a front cabin and a rear cabin. The upper shell is mainly divided into three sections, including an upper shell equipment section, an upper shell hoisting section and an upper shell cabin section.

[0034] The above-mentioned catamaran unmanned boat adopts a deep V boat type, which can ensure that the boat body has a smaller water entry angle to ensure that the wave-making resistance is reduced, and the line type of the tip of the bow of the boat is optimized, the curvature of the bow curve is increased, and the larger bow angle quickly transitions to the smaller angle of the midship and stern to take into account the longitudinal and transverse stability. The bow and stern are respectively provided with wave-suppression strips and wave-suppression plates. When sailing at high speed, the bow wave-suppression strips can reduce the bow splash and the waves on the deck. The waves rise along the hull and lose support here, forming a better wave-breaking effect. The stern wave-suppression plate can not only suppress the stern wave-making, but also is equivalent to the extension of the hull body, increasing the drainage area, and its sailing posture has also been adjusted and improved. The boat's comprehensive sailing performance such as rapidity, seaworthiness, and overload capacity has been further improved.

[0035] The upper shell of the above-mentioned catamaran unmanned boat adopts an inward-inclined design, and the mast is located in the upper shell equipment section. The mast also adopts an inward-inclined design. The mast provides a three-layer space board for placing the required load equipment, such as Figure 2 In the case of a submarine, the optoelectronic equipment and navigation radar equipment are located on the first and second layers of the mast respectively. The mast is fixedly connected to the hull structure.

[0036] The single-point hoist of the catamaran unmanned boat is located in the upper shell pod section, and the pod section coincides with the center of gravity of the catamaran, ensuring that the unmanned boat remains in a horizontal suspension state when it is lifted. Figure 3 The single-point crane shown in the figure consists of a base and a hook. The single-point crane is connected to the hull by bolts, and the hook is divided into a movable part and a fixed part. The guide cable of the mother ship is locked with the hook through the movable part, and the guide cable cannot automatically fall out inside the hook, ensuring the safety during the lifting operation.

[0037] The air inlet and exhaust port are located at the equipment section and pod section of the upper shell respectively. The air inlet also adopts an inward-inclined design. The air inlet and exhaust port run through the equipment cabin to ensure normal ventilation of the equipment cabin.

[0038] The mooring piles are located at the four corners of the upper shell to fix the boat when it is moored. In addition, when the catamaran is deployed and recovered, especially in severe sea conditions, the mooring piles can be connected to assist in lifting, reduce the shaking of the boat body, and ensure the stability of the boat body.

[0039] There are two propellers, which are installed at the tail of the two plates to propel the ship. The propellers can be water jet propellers or propeller propellers. When the power of the two propellers is inconsistent, the unmanned boat can be turned.

[0040] The main engine is located in the rear engine room, and the fuel tank is located in the front engine room. The front engine room roughly overlaps with the pod section, so that the fuel in the tank will minimize the impact on the lifting operation of the unmanned boat. The equipment cabin is equipped with generators, batteries, autonomous navigation equipment, environmental collection equipment, communication and navigation equipment and other necessary equipment to ensure that the unmanned boat can travel and operate normally.

[0041] The unmanned boat constructed in this embodiment can also carry other mission payload equipment, including Doppler current profiler, weather monitor and sea surface temperature meter equipment, temperature and salinity meter equipment, etc. At the same time, the hull is made of composite carbon fiber materials, and the bottom, side and deck are all designed with longitudinal skeletons, which ensures the structural strength of the hull while reducing the weight of the hull. The upper shell and the lower hull are assembled and disassembled by bolts.

[0042] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention includes but is not limited to the embodiments described in the specific implementation manner. Any other implementation manners derived by those skilled in the art based on the technical solution of the present invention also fall within the scope of protection of the present invention.
