Disclosure of Invention

The invention aims to provide a trimaran with a structure different from that of the existing trimaran.

The main body of the trimaran can be divided into an upper part, a middle part and a lower part which are connected, the upper part is an upper layer facility which refers to marine facilities such as a platform, a cab, a rest room, hoisting equipment and the like arranged at the upper part of the trimaran, the upper layer facility can be increased and reduced according to needs, the middle part is a space rod system structure formed by connecting rod pieces, the term of 'rod system structure' in encyclopedia of network encyclopedia is explained in detail, the rod system structure is simply a structure consisting of a plurality of rod pieces, all the rod pieces and all loads are positioned in the same plane, the structure is called a plane rod system structure, the structure is not positioned in the same plane, the structure is called a space rod system structure, the space rod system structure of the trimaran can be divided into two types according to nodes, the first type is a rigid node, the space rod system structure of the trimaran has the advantages that the structure is a rigid frame, the second structure is a mixed type structure with the coexistence of rigid nodes and hinged nodes, the space rod system structure of the trimaran plays a role of a strong framework for connecting three thin type ship bodies, meanwhile, an upper layer facility at the upper part is separated from the three thin type ship bodies at the lower part, the upper layer facility is lifted, a three-dimensional space is formed between the upper layer facility and the three thin type ship bodies, the lower part of the trimaran is provided with the three thin type ship bodies, and each cabin of the three thin type ship bodies is provided with a control device with an external access opening, so that when waves cross the three thin type ship bodies, water cannot enter each cabin, for example, the control devices of a personnel access opening are doors, the control devices of an equipment access opening are sealing covers, and the control devices of an oil tank, a fresh water tank and a ballast water tank are valves; in order to facilitate the people and materials to come in and go out of the middle hull, the trimaran is provided with the enclosure with the shape similar to that of the enclosure of the submarine command console, the lower opening of the enclosure is communicated with the middle hull, the upper opening of the enclosure can be communicated with the platform, the upper opening of the enclosure can also be communicated with the cab and the rest room, the enclosure can be streamlined like the enclosure of the submarine command console and can also be made into a front-end streamline rear-end square, the volume of the enclosure is designed according to needs, the larger the volume of the enclosure is, the larger the force impacted by waves is, the position of the enclosure can be in the middle of the middle hull and can also be close to the front or the back, the purpose is that the people or the materials can conveniently go up and down in the enclosure, and two or more enclosures can be arranged if needed; the space rod system structure of the trimaran can bear bending and torsional moments generated when the trimaran is used, the space rod system structure of the trimaran can adopt rod pieces with different section shapes and different materials, the strength of the rod pieces is different, the number of the used rod pieces is different, the distribution of the rod pieces can be different under the condition of meeting the strength requirement, the connection between the rod pieces of the space rod system structure of the trimaran is preferably fixed, the reference space rod system structure is provided with a power transmission tower consisting of the rod pieces and a building tower crane main body part consisting of the rod pieces, and part of the rod pieces of the space rod system structure of the invention can extend into the interior of the thin hull to strengthen and strengthen the connection with the thin hull; the height of the space rod system structure is determined according to the wave height of the water area used by the trimaran, if the wave height is high, the height of the space rod system structure of the trimaran is high, the trimaran allows the wave to cross three thin type hulls when in use, the trimaran is designed to resist the wave below the wave height and can cross the three thin type hulls, and the wave only impacts the three thin type hulls and part of the space rod system structure and does not impact the upper facility of the trimaran when passing under the upper facility; when the ship sails in water, the waves with different wave heights, different wavelengths, different wave speeds and different waveforms have different influences on the ship, and the waves with the same wave heights, wavelengths, wave speeds and waveforms also have different influences on the ships with different shapes and sizes, so the experiment under the real wind and wave conditions is a feasible method for determining the height of the space rod system structure of the trimaran, the manufacturing process of the trimaran can be that firstly, a trimaran for experiment is designed and manufactured, the three thin type ship bodies and the upper-layer facilities of the trimaran for experiment are required to be the same as those of the trimaran designed and used in the next step, when the trimaran for experiment sails in water, the wave height of the waves which just can not impact the upper-layer facilities is just the wave height which the trimaran for experiment can be designed to resist the wave height, the height of the space rod system structure of the trimaran for experiment can be referred to, under the condition that the three thin type and the upper-layer facilities are not changed, the invention provides a trimaran capable of resisting different wave heights by changing the height of a space rod system structure; when the trimaran is sailed in water, the weather suddenly changed and the wind waves are increased suddenly and exceed the designed wave height, a few waves impact the upper-layer facilities, and the upper-layer facilities of the trimaran can bear the impact of the few waves and recommend sailing backwards when the weather suddenly changed and the wind waves exceed the designed wave height.

The trimaran can be made into a small waterplane trimaran, namely a trimaran with a middle hull being a small waterplane and two side hulls being not small waterplane, and a trimaran with a middle hull and two side hulls being small waterplanes.

In order to further reduce the resistance of the trimaran in navigation, the cross section of the rod of the space rod system structure which can be impacted by waves of the trimaran is in a forward pointed and backward square shape, a two-head pointed shape or a streamline shape, and the cross section shape of the rod needs to be selected according to the difficulty and the actual requirement of material manufacturing.
