Embodiment 1

[0045] Please refer to Figure 1-3 As shown, a power device includes an impeller 1 connected to a rotating shaft 2; a fluid channel 6 is provided in the impeller housing, and the fluid channel communicates with a plurality of first vents 4 uniformly distributed in the length direction of the entire leeward surface 302 The fluid channel 6 is provided with a turbulence device 7 that prolongs the passage of the fluid and is concave-convex on the surface. The gas ports 8 communicate with each other; between the entire windward side and the leeward side of the impeller, a plurality of ventilation pipes 9 are evenly distributed to communicate with each other and / or a plurality of second ventilation ports 5 uniformly distributed on the windward side communicate with the fluid channel.

[0046]Wherein the air intake area of ​​the first vent 4 is larger than the intake area of ​​the second vent 5 and the vent pipe 9 .

[0047] The turbulence device 7 includes: a turbulence surface con...

Embodiment 3

[0076] Please refer to Figure 1-Figure 5 , different from Embodiment 2, the power unit is a bladeless water turbine driven by water to generate electricity. The water turbine includes a stator, and a rotor rotating in the stator (not drawn for common knowledge), and the rotor is exactly the impeller 1 connected by the rotating shaft 2, which is the water turbine.

[0077] A fluid passage 6 is provided around the turbine casing, and a flow turbulence device 7 is provided in half of the fluid passage around the turbine casing. It is the backwater surface with a fast flow rate, and a plurality of first water outlets and water outlets are arranged on the backwater surface The fluid channels are connected, thereby forming a high-speed fluid layer 303 on the backwater surface; and the other half of the fluid channel is the upstream surface with a slow flow rate because there is no turbulence device, and a plurality of second water outlets 5 are set on the upstream surface to commun...

Embodiment 4

[0086] Please refer to Figure 1-Figure 6 , different from the above, the power device is a one-stage or multi-stage impeller 1 connected to the rotating shaft 2; the first vent 4 is uniformly distributed on the leeward surface 302 of at least one stage of the impeller, and the fluid channel 6 is connected to the impeller housing in the length direction The tail exhaust port 8 on the farthest blade tip communicates; on the windward side and the leeward side of the impeller, it communicates with a plurality of evenly distributed ventilation pipes 9 and / or a plurality of second ventilation ports 5 on the windward side communicate with each other through fluid passages. The first air vent 4 on the windward side communicates with each other.

[0087] Further, the uniformly distributed first vents on the leeward surface of the impeller can communicate with the hollow rotating shaft 2 through the fluid passage 6, and the hollow rotating shaft 2 passes through the suction pipe 306 an...

Abstract

The invention discloses a power device comprising a rotating shaft and an impeller connected with the rotating shaft. The windward side and the leeward side of the impeller partially or wholly communicate through different fluid pressures between the windward side and the leeward side through a plurality of air vents. A fluid channel arranged in an impeller shell communicates with a plurality of first air vents in the length direction of the leeward side so that a high-speed fluid layer can be formed on the leeward side, and a pressure difference is generated between low pressure of the high-speed fluid layer and high pressure of the windward side. Due to the pressure difference, the high pressure on the windward side is made to find a pressure relief port, the pressure difference is transferred from the plurality of air vents to the low pressure on the leeward side, and the fluid resistance is reduced. According to the power device, the high-pressure fluid on the windward side transfers the pressure difference to the low-pressure high-speed fluid layer through the multiple air vents, the fluid pressure is reduced, the pushing force is generated, and therefore the pushing force of the power device is remarkably improved on the premise that additional power is not increased.

Description

[0001] This case is a divisional application based on the invention patent with the application date of 2017-04-26, the application number of 201710281776.9, and the title of "a power device driven by external force or power" as the parent case. technical field [0002] The invention relates to power technology, in particular to a power device.
