Since the water spray box installed on the hydropower assist rotating disk has a water spray hole at one end and a piston component installed at the other end, the reverse force generated when the mountain spring water is sprayed out from the water spray hole is transmitted to the hybrid power output receiving rod through the piston rod at the piston end, thereby driving the hybrid power output receiving disk to rotate together with the hybrid power output disk and forming a balance; at the same time, the external energy assist power input disk installed at the lower part of the outer rotating cylinder drives the outer rotating cylinder to rotate together with the hydropower assist rotating disk and the water spray box under the assisting effect of external energy. At this time, since the two ends of the water spray box form a balance, the external energy required to drive the hydropower assist rotating disk and the water spray box to rotate is relatively small. However, since the rotation speed of the hydropower assist rotating disk is increased, the rotation speed of the hybrid power output disk is also increased, and then the hybrid power output by the hybrid power output disk is greatly improved, so that the conversion efficiency of the power water is higher. At the same time, since the power water input pipe is small, the required water flow is not large, so small flow and high head water can be used. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The following description is in the form of examples, but the protection scope of the present invention should not be limited thereto.

[0026] The high-efficiency hybrid power output device of this embodiment is composed of a machine base 3, a power water input component, a water energy assist component, an external energy assist component and a power output component. The power water input component is composed of a power water input pipe 2 and a power water input pipe connecting flange 1. The machine base 3 is installed on the power water input pipe 2.

[0027] The water power assist assembly is composed of an inner cylinder, an outer rotating cylinder 7, a water power assist turntable 9 and one or more groups (three groups in this example, two groups, four groups or other numbers of groups) of hydrodynamic components evenly arranged on the water power assist turntable 9.

[0028] The lower end of the inner cylinder is installed on the upper end of the power water input pipe 2, and the inner cavities of the two are connected; the inner cylinder is composed of an upper inner cylinder 23, a middle inner cylinder 24 and a lower inner cylinder 27, which are connected and connected as a whole. The upper inner cylinder 23 has a top (i.e., it is closed), the diameter of the middle inner cylinder 24 is smaller than the diameter of the upper inner cylinder 23 or the lower inner cylinder 27 or smaller than the diameter of the upper inner cylinder 23 and the lower inner cylinder 27, and more than two drainage holes 25 are opened on its cylinder wall. The upper inner cylinder 23 and the lower inner cylinder 27 are respectively provided with journals for passing the inner rings of the upper bearing 12 and the lower bearing 6.

[0029] The inner cavity parts at the upper and lower ends of the outer rotating cylinder 7 are provided with inner hole steps for installing the upper bearing 12 and the lower bearing 6. Inner seals (for preventing water outside the middle inner cylinder 24 from penetrating into the upper bearing 12 and the lower bearing 6) are also installed respectively at the lower part of the upper bearing 12 and the upper part of the lower bearing 6 of the outer rotating cylinder 7. External seals (for preventing water from penetrating into the upper bearing 12 from above and the lower bearing 6 from below) are also installed respectively on the inner hole wall of the water-powered turntable 9 (for installing the upper inner cylinder 23) and the inner hole wall of the outer rotating cylinder lower pressure cover 4 (installed at the lower end of the outer rotating cylinder 7).

[0030] The outer drum 7 is sleeved on the inner drum, and the water-powered turntable 9 is installed on the upper end of the outer drum 7 .

[0031] The middle of the water-powered rotating disc 9 is provided with a downwardly facing convex ring for positioning the outer ring of the upper bearing 12 .

[0032] The hydrodynamic component is composed of a water diversion pipe 8, a water spray box 10 and a piston component. The water spray box 10 is installed on the upper edge of the water-powered turntable 9, one end of which is provided with a water spray hole 11, and the other end is provided with a piston component; the piston component is composed of a piston 20 and a piston rod 28, the piston 20 is installed in the inner cavity of the water spray box 10, the piston rod 28 is installed at one end of the piston 20 (the other end faces the middle of the water spray box 10), and the piston rod 28 passes through the piston rod hole on the other end face of the water spray box 10 (the end thereof abuts against the hybrid power output receiving rod 19 of the power output assembly).

[0033] The lower end of the water guide pipe 8 is connected to the inner cylinder (ie, the cavity formed by the concave outer cylindrical surface of the middle inner cylinder 24 ), and the upper end passes through the water power assisting turntable 9 and is connected to the inner cavity of the water spray box 10 .

[0034] The external energy assist component is composed of an external energy assist power input disk 5 and a locking piece 26. The external energy assist power input disk 5 is a pulley, sprocket, gear or other component capable of transmitting rotational motion (set as a pulley in this example), installed at the lower part of the outer rotating drum 7, and fixed by a locking piece 26 (a nut or a retaining ring or other component capable of fixing and positioning).

[0035] The power output assembly is installed on the water power assist turntable (9) and the top of the inner cylinder, and is composed of a hybrid power output main shaft 16, a hybrid power output shaft sleeve 17, a hybrid power output bearing 18, a hybrid power output receiving rod 19 and a hybrid power output disc 15.

[0036] The hybrid output main shaft 16 is an inverted "T"-shaped stepped shaft, which is installed on the upper top surface of the upper inner cylinder 23; the hybrid output shaft sleeve 17 is provided with a hybrid output bearing 18 (the hybrid output bearing 18 can be provided as one or more, and when there are two, it is divided into a hybrid output upper bearing and a hybrid output lower bearing, which are respectively installed on the upper and lower parts of the hybrid output main shaft 16, and a bushing 13 is installed between two adjacent ones), and is sleeved on the hybrid output main shaft 16. A hybrid output shaft seal 22 is also installed in the lower end inner cavity of the hybrid output shaft sleeve 17 (to prevent the water sprayed from the water spray box 10 from penetrating into the hybrid output bearing 18).

[0037] The hybrid output disc 15 is mounted on the upper end of the hybrid output sleeve 17 and fixed by the pressure plate 14; one end of the hybrid output receiving rod 19 is connected to the outer cylindrical surface of the lower part of the hybrid output sleeve 17 (a hybrid output receiving disc 21 may be arranged between the hybrid output receiving rod 19 and the hybrid output sleeve 17, the middle of which is arranged at the lower part of the hybrid output sleeve 17, and the hybrid output receiving rod 19 is arranged at the edge of the hybrid output receiving disc 21), and the other end is arranged at the tail end of the piston rod 28. The hybrid output disc 15 is a pulley, a sprocket, a gear or other component capable of transmitting rotational motion (set as a pulley in this example).

[0038] Before use, the base 3 is first fixed on the foundation, and then the mountain spring water is connected to the power water input pipe connection flange 1 through the water diversion pipe and connected to the power water input pipe 2. Then, the external energy power source is connected to the external energy power input disk 5 through a belt, and the hybrid power output disk 15 is connected to the power output device (such as an engine or other power conversion device, etc.) through a belt.

[0039] When in use, the mountain spring water enters the power water input pipe 2 through the water pipe, then enters the inner cavity of the middle inner tube 24, and then enters the cavity formed by the concave outer cylindrical surface of the middle inner tube 24 through the water leakage hole 25 on the tube wall, and then enters the water pipe 8 and the water spray box 10 respectively through the cavity, and further sprays out from the water spray hole 11 at one end of the water spray box 10. At the same time, the piston 20 and the piston rod 28 are pushed to the other end of the water spray box 10. Since the tail end of the piston rod 28 abuts against the hybrid power output receiving rod 19, the hybrid power output disk 15 is further driven to rotate. At the same time, the external energy boosting power source drives the external energy boosting power input disk 5 to rotate through the belt, and then drives the water energy boosting rotating disk (9) together with the water spray box 10 and the piston rod 28 to rotate. Since the reverse thrust generated by the water sprayed from the water spray hole 11 at one end of the water spray box 10 is balanced with the thrust of the piston rod 28 pushing the hybrid power output receiving rod 19, the power required by the external energy-assisted power source is relatively small, and it is only necessary to push the water-assisted turntable (9) together with the water spray box 10 and the piston rod 28 to rotate. However, due to the driving effect of the external energy-assisted power source, the rotation speed of the water-assisted turntable (9) together with the hybrid power output disk 15 is increased, thereby increasing the output power of the hybrid power output disk 15, and further, the power conversion efficiency of the mountain spring water is greatly improved.

[0040] The high-efficiency hybrid power output device of the present invention is suitable for use in mountainous areas with inconvenient transportation and power shortage.
