The energy output wheels are two, and each energy output wheel is respectively connected with the active rope and the driven rope, and the active rope can be The driven rope is towed and the energy output wheel can be rotated to output energy.

 The action process of the invention is as follows: the active rope traction motor pulls the active rope to completely relax the center umbrella rope, and the umbrella clothes are opened under the fluid pushing. Once the umbrella clothes open the active rope traction motor, the motor is stopped, and the umbrella opened under the fluid pushing. The body in turn pulls the active rope to drive the energy output wheel to output energy; when the predetermined stroke is reached, the knot touches the card board, and the driven rope traction motor pulls the center umbrella rope, and the airbag shrinks under the force of the fluid, and returns to the initial In this state, the operation is repeated back and forth to concentrate the fluid kinetic energy and output the output through the energy output wheel.

 The preferred solution in the present invention is that the umbrella bodies are combined in pairs, and the active ropes of each umbrella body respectively connect or drive the driven ropes of the other umbrella body, thereby simplifying the changing mechanism, and using between the edge umbrella rope and the active rope A ring is connected, and the central umbrella rope passes through the ring and is connected to the driven rope.

 When applied to the air, when the wind speed is low or the installation height is low, a strip-shaped light air bag can be attached to the longitudinal direction of the umbrella to facilitate the opening of the umbrella.

 The invention has the beneficial effects that the invention has low construction cost, high power, high efficiency, simple maintenance and wide application. DRAWINGS
