Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to the drawings in the specification, a hydroelectric generator with overload protection comprises a main body (10), the main body (10) is provided with a water inlet (20) and a water outlet (30), a motor (40) is arranged in the main body (10), the motor (40) is connected with an impeller (50) in a matching way, the water inlet (20) comprises a first water inlet (21) and a second water inlet (22), a plug (60) capable of adjusting the water passing area is arranged in the water passing channel between the second water inlet (22) and the water outlet (30), the plug (60) is provided with a sealing ring (61), the plug (60) is connected with a spring (70) in a matching way, the utility model realizes that the water inlet end is in a high pressure or low pressure state through the design of the structure, the impeller (50) can be kept within a certain rotating speed range, overload operation is prevented, and the service life of the motor (40) is greatly prolonged.

Further, the main body (10) comprises an upper body (11) and a lower body (12), the motor (40) is arranged in the lower body (12), the water inlet (20) is arranged on the upper body (11), the water outlet (30) is arranged on the lower body (12), more specifically, the upper body (11) comprises an end cover (16) and a cylinder (17), the first water inlet (21) is arranged on the end cover (16), the second water inlet (22) is arranged on the column body (17), in a preferred embodiment, said first water inlet openings (21) are arranged in an annular array on the end cap (16), the second water inlets (22) are arranged on the column (17) in an annular array, the water outlets (30) are arranged on the lower body (12) in an annular array, more particularly, the number of the first water inlets (21) is three, and the number of the second water inlets (22) is four.

Furthermore, first water inlet (21) are provided with the inclination, second water inlet (22) do not have the inclination, the design of inclination has guaranteed that only the rivers that flow in from first water inlet (21) can be oblique rivers to guaranteed that drive impeller (50) pivoted power is mainly by the rivers drive that first water inlet (21) flowed through.
