Description

Technical Field

[0001] The utility model relates to the technical field of water filters, and more particularly to a small-scale water filter for hydropower generation pipelines. Background Art

[0002] Hydropower generation is the science and technology that studies the technical and economic aspects of engineering construction and production operations that convert water energy into electrical energy. Hydropower generation primarily utilizes the potential energy contained in water bodies. To achieve this conversion, various types of hydropower stations are required. Small hydropower generation pipeline water filters are a type of equipment used in small hydropower generation systems. Their primary function is to filter out impurities and suspended matter from the water, protecting turbines and generator equipment, extending their service life, and improving power generation efficiency.

[0003] Most of the existing small-scale hydropower generation pipeline water filters use filter screens to filter impurities in the water. However, after a period of use, impurities tend to adhere to the surface of the filter screen, thereby affecting the water flow rate inside the water filter.

[0004] Moreover, when the water filter is installed, the connecting pipes on both sides are mostly fixed structures, which makes it unsuitable for connecting with hydropower generation pipelines at different distances in the future. External pipes are needed for extension, which affects the installation efficiency. Utility Model Content

External connection mechanisms are provided on the water inlet pipe 12 and the water outlet pipe 13.

[0032] In this embodiment, the external mechanism includes a limiting ring 14, which is fixedly arranged at one end of the water inlet pipe 12 and the water outlet pipe 13. The outer ends of the water inlet pipe 12 and the water outlet pipe 13 are movably provided with an adjusting tube 15, and one end of the adjusting tube 15 is fixedly provided with a clamping ring 16. The clamping ring 16 is in close contact with the outer wall of the water inlet pipe 12 and the water outlet pipe 13. A threaded hole 17 is opened on the outer wall of the adjusting tube 15, and a tightening screw 18 is provided inside the threaded hole 17. One end of the tightening screw 18 is pressed against the outer wall of the water inlet pipe 12 and the water outlet pipe 13.

[0033] More specifically, under the thrust of the water body, the spring 6 on one side of the filter plate 8 will be stretched. As the thrust of the water flow changes and the elasticity of the spring 6, the filter plate 8 will vibrate left and right inside the shell 1 to shake off impurities on its surface to achieve a self-cleaning function, which is convenient for long-term use. When connecting with a small hydropower generation pipeline, one end of the filter plate 8 can be separated from the water inlet pipe 12 and the water outlet pipe 13 by rotating the tightening screw 18, and then the protruding length of the adjusting tube 15 can be adjusted to connect hydropower generation pipelines at different distances. After adjustment, the tightening screw 18 is tightened again, and one end of the filter plate 8 is pressed against the outer wall of the water inlet pipe 12 and the water outlet pipe 13 to achieve a fixing effect and facilitate installation.

[0034] See also Figure 2-Figure 4 As an implementation method for disassembling and cleaning the filter plate 8: a first conical surface 19 is provided on the lower end surface of the shell 1, and a second conical surface 20 is movably provided inside the first conical surface 19.

During installation, the second conical surface 20 can be inserted into the first conical surface 19, and the fastening nut 24 can be installed on the threaded column 23 so that its upper end surface is against the lower end surface of the sealing plate 21 to achieve a fixing effect.

[0037] Specifically, the user can connect the regulating pipe 15 to the water conservancy pipeline through the external flange 26.

[0038] To sum up, when the overall equipment is in use: under the thrust of the water body, the spring 6 on one side of the filter plate 8 will be stretched. As the thrust of the water flow changes and the elasticity of the spring 6, the filter plate 8 will vibrate left and right inside the shell 1 to shake off impurities on its surface to achieve a self-cleaning function, which is convenient for long-term use. When the device needs to be installed with water conservancy pipes at different distances, the tightening screw 18 can be rotated to separate one end of the filter plate 8 from the water inlet pipe 12 and the water outlet pipe 13, and then the extension length of the adjusting tube 15 can be adjusted to connect water conservancy power generation pipes at different distances. After adjustment, the tightening screw 18 is tightened again, and one end of the filter plate 8 is pressed against the outer wall of the water inlet pipe 12 and the water outlet pipe 13 to achieve a fixing effect, which is convenient for subsequent installation. When the filter plate 8 needs to be disassembled, the user can remove the second cone surface 20 from the inside of the first cone surface 19 by removing the fastening nut 24, and then remove the countersunk screw 11 to remove the filter plate 8 from the inside of the shell 1 for easy cleaning.
