[0001] The utility model relates to the technical field of water filters, in particular to a water filtering device for a hydropower pipeline. Background Technique

[0002] Hydropower generation is a way of power generation, mainly using the kinetic energy of water flow to be converted into the mechanical energy of the worm wheel rotation in the water turbine, and then converting the mechanical energy into electrical energy through the generator, and distributing the electric power to users through the power transformation and power transmission and distribution equipment.

[0003] Chinese Patent Publication No. CN213407909U discloses a water filter for a hydropower pipeline, which includes a water filter body. Installation plates are fixedly installed on the left and right sides of the inner wall of the water filter body. The top ends of the installation plates are fixedly installed with filter plates through springs. A filter screen is fixedly installed on the inner bottom end of the water filter body. The filter screen is square conical. Filter residue grooves are arranged on the left and right sides of the filter screen. Leakage holes are opened on the left and right sides of the outer wall of the water filter body, and valves are installed at the leakage holes. The combined use of the filter plate, the spring and the installation plate can prevent impurities in the water from being easily stuck in the internal holes of the filter plate. The combined use of the filter screen, the valve, the leakage hole and the filter residue groove solves the problem that the existing filter cannot discharge the separated impurities, and avoids the situation that the blockage and the inability to discharge materials affect the normal use of the filter.

[0004] However, the above technical solution has the following problems: When using this water filter to filter water flow, smaller and lighter particles in the water flow will adhere to the conical filter screen and are difficult to be driven by the water flow. The gradual stacking of particles will affect the normal use of the filter. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problems existing in the background technique, and to propose a water filtering device for a hydropower pipeline, which makes the flow velocity in the water flow inconsistent through a diversion frame part, and then the fan blades drive the cleaning component to clean the filter screen under the push of the water flow with different flow velocities, so as to avoid the influence of sundries on the filtering efficiency of the water filtering device.

[0006] The technical solution of the utility model, a water filtering device for a hydropower pipeline, includes: a filtering frame, which has a filtering frame part and a diversion frame part. The filtering frame part has a filtering cavity part and a diversion cavity part that are interconnected. The diversion frame part is located between the filtering cavity part and the diversion cavity part; a filtering component, which is arranged on the filtering frame. The filtering component includes an installation ring and a fixing frame arranged on the filtering frame, and a filter screen with two ends respectively connected to the installation ring and the fixing frame; a cleaning mechanism, which is arranged on the filtering frame. The cleaning mechanism includes a connecting column arranged on the filtering frame, an installation column coaxially fixed between the connecting column and the fixing frame, a fan blade rotatably arranged on the connecting column, and a cleaning component rotatably arranged on the installation ring and the fixing frame. The fan blade is drivingly connected to the cleaning component.

[0007] Preferably, the cleaning component includes a cleaning ring rotatably arranged on the fixing frame, a connecting ring with two ends respectively connected to the cleaning ring and the fan blade, and a plurality of cleaning blocks detachably arranged on the cleaning ring along the circumference. The plurality of cleaning blocks are all in sliding contact with the surface of the filter screen.

[0008] Preferably, a miscellaneous storage box is detachably arranged on the filter rack. The miscellaneous storage box is communicated with the filter cavity part, and the miscellaneous storage box has a diversion plate part arranged obliquely.

[0009] Preferably, the mounting ring has a rotating groove and a guiding groove that communicate with each other, and the guiding groove faces the miscellaneous storage box.

[0010] Preferably, a plurality of moving frames are arranged on the cleaning ring, and a plurality of impurity pushing blocks are arranged on the plurality of moving frames. The plurality of moving frames and the impurity pushing blocks are all located in the rotating groove.

[0011] Preferably, the diversion frame part has a diversion channel and a plurality of flow channels, and the cross-section of the diversion channel gradually decreases along the water flow direction.

[0012] Preferably, one connecting pipe is slidably communicated with each end of the filter rack, and both of the two connecting pipes have flange parts

[0013] Compared with the prior art, the utility model has the following beneficial technical effects:

[0014] When the utility model is in use, water flows into the diversion cavity part through the connecting pipe. During the flowing process of the water, due to the gradual decrease of the horizontal cross-section of the diversion channel, the flow rate gradually increases. The flow rates of the water flowing through the diversion channel and the flow channels are inconsistent. The water flow with a faster flow rate drives the fan blade to move under the interference of the slower water flow. The fan blade drives the cleaning component to clean the sundries on the surface of the filter screen, thereby improving the service life of the filter screen and preventing smaller sundries from blocking the holes on the surface of the filter screen and affecting the filtering efficiency of the water filtering device.

Detailed implementation manners

[0020] Embodiment 1

[0021] As Figures 1-4 shown, a water-filtering device for a hydroelectric power pipeline proposed in this embodiment includes a filter rack 1, a filtering assembly, and a cleaning mechanism. The filter rack 1 has a filter rack part 101 and a diversion rack part 102. The filter rack part 101 has a mutually connected filter chamber part 1011 and a diversion chamber part 1012. The diversion rack part 102 is located between the filter chamber part 1011 and the diversion chamber part 1012. The diversion rack part 102 has a diversion channel 1022 and a plurality of flow-through channels 1021. The cross-section of the diversion channel 1022 gradually decreases along the water flow direction; the filtering assembly is arranged on the filter rack 1. The filtering assembly includes a mounting ring 4 and a fixing frame 5 arranged on the filter rack 1, and a filter net 6 with two ends respectively connected to the mounting ring 4 and the fixing frame 5; the cleaning mechanism is arranged on the filter rack 1. The cleaning mechanism includes a connecting post 8 arranged on the filter rack 1, a mounting post 7 coaxially fixed between the connecting post 8 and the fixing frame 5, a fan blade 9 rotatably arranged on the connecting post 7, and a cleaning assembly rotatably arranged on the mounting ring 4 and the fixing frame 5. The fan blade 9 is drivingly connected to the cleaning assembly.

[0022] One connecting pipe 2 is slidably communicated with each end of the filter rack 1. Both connecting pipes 2 include a mutually connected connecting pipe part 21 and a flange part 22. Workers can adjust the distance between the two flange parts 22 according to the distance between the two pipes, and fix the connecting pipe 2 through two oppositely arranged clamping rings 3, so as to increase the versatility of the device.

[0023] When this embodiment is in use, water flows into the diversion chamber part 1012 through the connecting pipe 2. During the flowing process, the water flow velocity gradually increases because the horizontal cross-section of the diversion channel 1022 gradually decreases. The water flow velocities flowing through the diversion channel 1022 and the flow-through channels 1021 are inconsistent. The faster water flow pushes the fan blade 9 to move under the interference of the slower water flow. The fan blade 9 drives the cleaning assembly to clean the sundries on the surface of the filter net 6, thereby improving the service life of the filter net 6 and preventing smaller sundries from blocking the holes on the surface of the filter net 6 and affecting the filtering efficiency of the water-filtering device.

[0024] Embodiment 2

[0025] As Figure 3 shown, a water filtration device for a hydroelectric power pipeline proposed in this embodiment, compared with the first embodiment, in this embodiment, the cleaning assembly includes a cleaning ring 11 rotatably arranged on the fixing frame 5, a connecting ring 10 with two ends respectively connected to the cleaning ring 11 and the fan blade 9, and a plurality of cleaning blocks 12 detachably arranged on the cleaning ring 11 along the circumference. The plurality of cleaning blocks 12 are all in sliding contact with the surface of the filter screen 6.

[0026] When this embodiment is in use, the fan blade 9 is pushed by the water flow to drive the cleaning ring 11 to rotate through the connecting ring 10. The cleaning ring 11 drives the plurality of cleaning blocks 12 to be in sliding contact with the surface of the filter screen 6. The cleaning blocks 12 can be cleaning tools such as brushes, so as to avoid the holes on the surface of the filter screen 6 being blocked by impurities to the greatest extent.

[0027] Embodiment Three

[0028] As Figure 1 、 Figure 3 and Figure 4 shown, a water filtration device for a hydroelectric power pipeline proposed in this embodiment, compared with the first embodiment, in this embodiment, a miscellaneous storage box 15 is detachably arranged on the filter rack 1. The miscellaneous storage box 15 is communicated with the filter cavity part 1011. The miscellaneous storage box 15 has a diversion plate part arranged obliquely. The mounting ring 4 has a rotating groove and a guiding groove that communicate with each other. The rotating groove is an annular groove. The guiding groove faces the miscellaneous storage box 15. The diversion plate part is inclined towards the inside of the miscellaneous storage box 15, so as to prevent all the sundries in the miscellaneous storage box 15 from flowing out again under the drive of the water flow.

[0029] A plurality of moving frames 13 are arranged on the cleaning ring 11. A plurality of impurity pushing blocks 14 are arranged on the plurality of moving frames 13. The plurality of moving frames 13 and the impurity pushing blocks 14 are all located in the rotating groove. The impurity pushing blocks 14 are in sliding contact with both the inner diameter and the outer diameter of the rotating groove.

[0030] When this embodiment is in use, the sundries will flow to the rotating groove under the drive of the water flow. The cleaning ring 11 drives the impurity pushing blocks 14 to move through the plurality of moving frames 13. The impurity pushing blocks 14 will push the impurities into the miscellaneous storage box 15 through the guiding groove, so that when the filter water device is maintained, the worker can take out the miscellaneous storage box 15 to uniformly remove the sundries in the filter rack 1, thereby reducing the maintenance difficulty of the worker.

[0031] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to this. Within the scope of knowledge possessed by those skilled in the art to which the present invention pertains, various changes can be made without departing from the gist of the present invention.
