DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example

[0029] See Figures 1 to 5 As shown, a shaftless hydroelectric generator comprises an annular shell 1 and an annular gland 2, wherein the inner wall of the annular shell is provided with an avoidance annular groove 3, and the top of the side wall of the avoidance annular groove is provided with C-shaped slots 4 at equal intervals; in this embodiment, the inner diameter and outer diameter of the annular shell and the annular gland match each other, and at the same time, it only needs to be connected to the pipeline for use during assembly, and in actual application, an annular impeller seat 5, an annular magnetic steel seat 6 and an annular magnetic steel 7 are provided in the annular shell; during assembly, the annular magnetic steel seat is fixed to the outer surface of the annular impeller seat A coil is disposed on the annular surface, and between the annular magnetic steel seat and the C-shaped slot. In this embodiment, the coil is a conventional structure of the prior art and is not described in detail, but simply used. The annular magnetic steel is fixed within the annular magnetic steel seat and matches the position of the coil. The annular impeller seat is disposed within the annular housing and limited by an annular pressure cap, and the annular magnetic steel seat is rotatable within the avoidance annular groove. Blades 12 are fixed to the inner annular surface of the annular impeller seat. These blades drive the annular impeller seat and the annular magnetic steel seat to rotate, and power generation is achieved through the annular magnetic steel and the coil. Because the annular magnetic steel seat is fixed to the outer annular surface of the annular impeller seat, and the blades are located on the inner annular surface of the annular impeller seat, a central shaft is not required, which does not affect the flow rate of the pipeline water flow and does not cause central shaft wear, thereby improving operational stability and reliability. When water flows on the blades, the annular impeller seat drives the annular magnetic steel seat to rotate, and power generation is achieved through the annular magnetic steel and the coil group. The power generation principle is consistent with that of conventional water flow power generation, so it is not described in detail.

[0030] In this embodiment, a connection hole 8 is provided on the outer wall of the annular housing; the wire of the coil is passed through the connection hole, so as to facilitate the connection and use of the power generation.

[0031] Furthermore, in this embodiment, the length of the blades is less than the inner radius of the annular impeller seat. This allows the blades to effectively generate electricity without affecting the flow rate of the pipe, resulting in enhanced practicality. In actual applications, the annular impeller seat and blades are both constructed of plastic or metal.

[0032] In this embodiment, the inner top of the annular groove is provided with several bumps 9; the mounting surface of the annular gland is provided with positioning grooves 10 that align with the positions of the bumps. During assembly, the annular gland is fitted onto the top surface of the annular housing, and the bumps snap into place within the positioning grooves. This snap-fit ​​mechanism allows for rapid connection and positioning of the annular gland and the annular housing, while also limiting the position of the annular impeller seat, ensuring smooth and effective installation.

[0033] In actual application, an annular snap groove 11 is provided on the end surface of the annular magnetic steel seat; the annular magnetic steel snap is positioned in the annular snap groove. With the above structure, the convenience and stability of the installation of the annular magnetic steel can be improved.

[0034] The utility model has positive effects: the structure of the utility model is reasonably set up, it adopts an annular impeller seat, and the impeller is arranged on the inner wall of the annular impeller seat, thereby realizing a shaftless structure. After being connected to the pipeline, it does not affect the speed of the water flow in the pipeline, and there will be no shaft wear, which is conducive to improving service life and stability of use, and has strong applicability and good practicality.

[0035] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components described in the specification can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description is given here.

[0036] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to enumerate all embodiments here. However, obvious variations or modifications arising from the essence of the present invention remain within the scope of protection of the present invention.
