In this embodiment, 8 elastic impellers 15 are fixedly connected to each core transmission column 12. The outer side of the uppermost elastic impeller 15 is provided with a spiral diversion duct 11 which is in running fit with the uppermost elastic impeller. The inner cavity of the spiral diversion culvert 11 is divided into a positive power area and a negative power area, a horn mouth 113 and a main diversion plate 118 are respectively arranged on the front side and the rear side of the spiral diversion culvert 11, the horn mouth 113 faces the positive power area, a positive power area air outlet 119 is arranged on one side of the spiral diversion culvert 11, which is located in the positive power area, a negative power area opening 110 is arranged on one side of the spiral diversion culvert 11, which is located in the negative power area, and the positive power area air outlet 119 and the negative power area opening 110 are respectively located on two sides of the front end of the main diversion plate 118.

The core transmission column 12, the elastic impeller 15 and the spiral diversion duct 11 form the full diversion elastic impeller 1.
The core transmission column 12 is linked with a power generation transmission mechanism 2. The power generation transmission mechanism 2 comprises a first gear 21 and a second gear 22 which are meshed, and the second gear 22 is coaxially connected with the core transmission column 12. The first gear 21 is linked with a third gear through a first rotating shaft, the third gear is linked with a direct current generator, and the electric energy converted by the mechanical energy of the direct current generator is transmitted to a power distribution room on the ship body 3 and charges a storage battery. The direct current can be directly used for electrolytic hydrogen production, sea water distillation, gas compression and battery charging. In this embodiment, the first gear 21 and the second gear 22 are bevel gears, so that the rotating shaft connected with the first gear 21 can be horizontally arranged.
The base comprises a foundation truss girder 29. The power generation transmission mechanism 2 further includes a connection bracket 23, and the connection bracket 23 includes a bracket cover 233 and a support plate 231 respectively disposed at upper and lower sides of the second gear 22, and the bracket cover 233 is connected to the support plate 231. A second ball 24 is provided between the second gear 22 and the support plate 231. The support plate 231 is connected with a core column sleeve 232, the core drive column 12 is in running fit with the core column sleeve 232, and the core column sleeve 232 is connected with the foundation truss girder 29.

The spiral diversion culvert 11 is provided with a positive power area baffle 111 and a negative power area baffle 112, and an included angle is formed between the positive power area baffle 111 and the negative power area baffle 112 to form a horn mouth 113.

The blades of the elastic impeller 15 are made of elastic materials. The blade section of the elastic impeller 15 is curved.
The main deflector 118 is provided at its end with a tail 117. The tail 117 has a dovetail shape. When wind blows on the spiral guide duct 11, the spiral guide duct 11 rotates until the main guide plate 118 is substantially consistent with the lateral movement path of the wind due to the action of the main guide plate 118 and the tail fin 117, and at this time, the wind can enter the spiral guide duct 11 from the bell mouth 113 and act on the elastic impeller 15 to rotate.

When the core transmission column 12 rotates, the supporting ring 14 is driven to rotate relative to the connection turntable 13, and the rotation resistance can be reduced through the first balls 16.
The spiral guide duct 11 can guide the air flow to the right, the horn 113 can increase the area for collecting the air flow, and the air flow is guided to the positive power area of the elastic impeller 15. The air flow acts on the elastic impeller 15 and flows out from the positive power region air outlet 119 and the negative power region opening 110. Providing the negative power region opening 110 increases the smoothness of the exhaust and reduces the resistance of the positive power region. The elastic impeller 15 has the effect of improving the energy conversion rate because the wind receiving surface of the elastic She Zaizheng power area is increased and the wind receiving surface of the negative power area is reduced, thereby achieving the purpose of improving the collection efficiency to the greatest extent in a limited space.

The tension discs 25 on each core drive column 12 are arranged between upper and lower adjacent elastic impellers 15.
The marine hydrogen energy semi-submersible vessel hull 3 is also provided with a plurality of wind energy collection columns 200. The wind energy collection column 200 has the same structure as the bending-resistant wind energy collection column 20 in most parts, and is different from the bending-resistant wind energy collection column 20 in that the outer sides of the elastic impellers 15 on the wind energy collection column 200 are respectively provided with a spiral diversion culvert 11 in running fit with the elastic impellers 15. The bases of the wind energy collection column 200 and the bending-resistant wind energy collection column 20 are provided on the top of the hull 3 of the ocean hydrogen energy semi-submersible. The anti-bending wind energy collecting columns 20 are arranged in a row along the center line of the hull 3, and the wind energy collecting columns 200 are arranged in four rows and symmetrically arranged on the left and right sides of the row of anti-bending wind energy collecting columns 20, as shown in fig. 16 and 17.
