Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mining, in particular to a tubular shaftless power generation device for mines. Background Art
[0002] At present, most mining companies adopt the method of bottom-up mining. At this time, shallow surface water will flow into the shafts and tunnels. The water output of these gushing water is large and stable. In order to ensure the normal mining, these gushing water must be either discharged out of the well or discharged into the water storage tank underground. If it is discharged out of the well, it will consume electricity; if it is discharged underground, there will be a waste of water energy.
[0003] At present, whether the gushing water is discharged out of the well or discharged into the mine, it is necessary to use pipes to transport the gushing water. If the existing hydro-turbine generator is used for power generation, it is necessary to build a cofferdam and a flow channel. Due to the restrictions of the underground environment, the construction of cofferdams and flow channels requires the mine to be modified, and the cost of the modification is high.
[0004] In summary, a power generation device suitable for underground environments is needed. Utility Model Content
[0005] In order to overcome the shortcomings of the background technology, the utility model discloses a tubular shaftless power generation device for mines, which adopts the following technical solutions:
[0006] A tubular shaftless power generation device for mines comprises a stator and a rotor installed in the stator, wherein the stator is detachably installed on a water pipeline; the rotor is sleeve-shaped, and a plurality of turbine blades are evenly distributed inside the rotor; a bearing and a dynamic seal are arranged between the stator and the rotor.
[0007] To further improve the technical solution, the stator is detachably mounted on the water pipeline through an end face flange.
[0008] To further improve the technical solution, the bearing is an angular contact bearing.
[0009] To further improve the technical solution, the dynamic seal is an oil seal.
[0010] To further improve the technical solution, a filter is installed in the water delivery pipeline.
[0011] To further improve the technical solution, the inner diameter of the rotor is the same as the inner diameter of the water pipeline.
[0012] After implementing the above technical solution, the beneficial effects of the shaftless power generation device are:
[0013] The rotor of the shaftless power generation device is sleeve-shaped, and multiple turbine blades are evenly distributed inside the rotor. Unlike the existing hydraulic turbine generator, the turbine blades are shaftless and are integrated with the rotor. The beneficial effect of this design is that there is no need to use a turbine shaft to transmit power, and then the generator converts the power into electrical energy. Instead, the turbine blades and the generator are integrated into one, eliminating the transmission structure.
[0014] Compared with the background technology, the shaftless power generation device does not need to build cofferdams and flow channels, and can generate electricity by only using existing water pipelines, thereby reducing construction costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] As attached Figure 1 As shown, a tubular shaftless power generation device for mines comprises a stator 2 and a rotor 3 installed in the stator 2. The stator 2 is detachably installed on a water pipeline 1. The structure and function thereof are described in detail below.
[0022] Refer to the attached Figure 2 The stator is composed of a housing 2.1 and a stator core 2.2 installed in the housing 2.1. In order to realize detachable installation on the water pipeline 1, end flanges are provided at both ends of the housing 2.1.

[0023] Refer to the attached Figure 3 The rotor 3 is composed of a rotor sleeve 3.1 and a rotor core 3.3. The inner diameter of the rotor sleeve 3.1 is the same as the inner diameter of the water pipe 1, and four turbine blades 3.2 are evenly distributed inside the rotor sleeve 3.1.
[0024] Different from the existing water turbine generator, the four turbine blades 3.2 are shaftless, and the four turbine blades 3.2 are fixed inside the rotor sleeve 3.1 and are formed integrally with the rotor 3. The beneficial effect of this design is that there is no need to use a turbine shaft to transmit power, and then the generator converts the power into electrical energy, but the turbine blades and the generator are integrated into one, simplifying the structure of the entire water turbine generator.
[0025] Refer to the attached Figure 1 and attached Figure 4A bearing 4 and a dynamic seal 5 are provided between the stator 2 and the rotor 3.

When water flows into the water pipeline 1, the turbine blades 3.2 will drive the rotor 3 to rotate, and the shaftless generator starts to generate electricity. The generated electricity is frequency modulated and rectified for use in underground operations.
