A plurality of cloth bags 707 are mounted on the plurality of front frame transverse stay cords 8042, the plurality of front frame longitudinal stay cords 8043, the plurality of rear frame transverse stay cords 8052, and the plurality of rear frame longitudinal stay cords 8053; the opening edge of each cloth bag 707 is arranged on two adjacent front frame transverse pull ropes 8042 and one front frame longitudinal pull rope 8043; the opening edge of each cloth bag 707 is mounted on two adjacent front frame transverse pull ropes 8042 through a cloth bag opening fixing point I7071, a cloth bag opening fixing point II 7072, a cloth bag opening fixing point III 7073 and a cloth bag opening fixing point IV 7074, and is mounted on two adjacent front frame longitudinal pull ropes 8043 through a cloth bag opening fixing point V7075 and a cloth bag opening fixing point VI 7076; the opening edge of the cloth bag 707 is tightened by the cloth bag opening fixing point I7071, the cloth bag opening fixing point II 7072 and the cloth bag opening fixing point V7075, so that a triangular opening which cannot be closed is formed at part of the opening part of the cloth bag 707; the cloth bag opening fixing point III 7073, the cloth bag opening fixing point IV 7074 and the cloth bag opening fixing point VI 7076 also tighten the opening edge of the cloth bag 707 to ensure that a triangular opening which cannot be closed is formed at part of the opening part of the cloth bag 707; the opening edge of the cloth bag 707 between the first cloth bag opening fixing point 7071 and the second cloth bag opening fixing point 7072 is loose, and the opening edge of the cloth bag 707 at the position can be inward to form an arc shape or outward to form an arc shape; the opening edge of the cloth bag 707 between the cloth bag opening fixing point three 7073 and the cloth bag opening fixing point four 7074 is loose, and the opening edge of the cloth bag 707 at the position can be inward to form an arc shape or outward to form an arc shape; the closed edge of each cloth bag 707 is mounted on the rear frame longitudinal pull rope 8052 through a first cloth bag closed fixing point 7077 and a second cloth bag closed fixing point 7078, and the second cloth bag closed fixing point 7078 is mounted on the upper frame 705 to tighten the closed edge of the cloth bag 707 on the rear frame longitudinal pull rope 8052.

When the opening of the cloth bag 707 faces the water flow direction, the opening edge of the cloth bag 707 between the first cloth bag opening fixing point 7071 and the second cloth bag opening fixing point 7072 is outward to form an arc shape; the opening edge of the cloth bag 707 between the cloth bag opening fixing point three 7073 and the cloth bag opening fixing point four 7074 is outward to form an arc shape; the opening of the cloth bag 707 is opened, the cloth bag 707 is filled and blocks a large amount of flowing water with speed, and the cloth bag 707 obtains great thrust. When the closed end of the cloth bag 707 faces the water flow direction, the opening edge of the cloth bag 707 between the first cloth bag opening fixing point 7071 and the second cloth bag opening fixing point 7072 is inward to form an arc; the opening edge of the cloth bag 707 between the cloth bag opening fixing point three 7073 and the cloth bag opening fixing point four 7074 is inward to form an arc shape; the opening of the cloth bag 707 is closed, the cloth bag 707 blocks a small amount of flowing water with speed, and the cloth bag 707 obtains small thrust. The opening of the cloth bag 707 generates a thrust difference in the water flow direction and the closing of the cloth bag 707 generates a thrust difference in the water flow direction, so that the cloth bag type flow capturing system 8 surrounds and drives the first transmission rod 901 to rotate, and the first transmission rod 901 drives the generator system 15 to generate electricity through the speed reducer system 14.
