[0097] Further, one end of the first drain pipe 380 away from the shunt box 310 is closed by a third sealing plate 381. The inner diameter of the first drain pipe 380 is greater than the caliber of the drain port 312.

[0098] The control core 400 extends into the first drain pipe 380 through the drain port 312.

[0099] The filtering mechanism 300 further comprises a second drain pipe 390.

[0100] The second drain pipe 390 is connected to the side wall of the first drain pipe 380 and located at one end of the first drain pipe 380 close to the shunt box 310. The side wall of the first drain pipe 380 is provided with a second communication hole 391 in communication with the second drain pipe 390.

[0101] The first drain pipe 380 is provided with a first stop flange 382 and a second stop flange 383. The first stop flange 382 and the second stop flange 383 are both located on the side of the second drain pipe 390 away from the shunt box 310. The first stop flange 382 and the second stop flange 383 are spaced apart, and the second stop flange 383 is located on the side of the first stop flange 382 away from the second drain pipe 390. The second stop flange 383 is spaced apart from the third sealing plate 381.

[0102] The first drain pipe 380 is provided with a piston 384, which is fitted between the first stop flange 382 and the second stop flange 383. Along the axial direction of the first drain pipe 380, the piston 384 is slidingly fitted in the first drain pipe 380 and slidingly sealed.

[0103] A resilient member (not shown in the figure) is abutted between the piston 384 and the third sealing plate 381, and the resilient member passes through the second stop flange 383.

[0104] The control core 400 is further fixedly connected with a third blocking member 430.

[0106] In this embodiment, the piston 384 is fixedly connected with a driving rod 385 on the side away from the shunt box 310. The driving rod 385 extends along the axial direction of the first drain pipe 380 and penetrates through the third sealing plate 381.

[0107] The filtering mechanism 300 further comprises an inflation cylinder (not shown in the figure).

[0109] When the piston 384 moves towards the second stop flange 383, the driving rod 385 drives the rod of the piston 384 to make the inflator inhale. When the piston 384 moves towards the first stop flange 382, the driving rod 385 drives the rod of the piston 384 to make the inflator exhaust, so that the inflator inflates into the first drain pipe 380 through the inflating pipe 386.

[0110] Specifically, the driving rod 385 is a hollow structure.

[0111] The end face of the control core 400 close to the piston 384 is also coaxially fixedly connected with an extension rod 440, and the extension rod 440 is arranged in extension along the axial direction of the control core 400. The extension rod 440 penetrates the piston 384 and extends into the driving rod 385.

[0112] The diameter of the extension rod 440 is smaller than the inner diameter of the driving rod 385. The end of the extension rod 440 away from the control core 400 is fixedly connected with an end block 450, and the outer diameter of the end block 450 is greater than the diameter of the extension rod 440. In this embodiment, along the axial direction of the driving rod 385, the end block 450 is slidably cooperated in the driving rod 385, and a gap is left between the end block 450 and the inner wall of the driving rod 385 for balancing the gas pressure.

[0113] When the control core 400 is located at the first sliding stop point, the side surface of the end block 450 close to the extension rod 440 is located in the same plane as the side surface of the second stop flange 383 close to the first stop flange 382.

[0114] When the control core 400 is located at the second sliding stop point, the end block 450 is located at the side of the second stop flange 383 close to the first stop flange 382.

[0115] The controller is configured to control the driver to drive the control core 400 to move from the first sliding stop point to the second sliding stop point.

[0116] Along the axial direction of the control core 400, the outer diameter of the first blocking piece 410 decreases from the end close to the second blocking piece 420 to the end away from the second blocking piece 420.

[0117] Along the axial direction of the control core 400, the outer diameter of the second blocking member 420 decreases gradually from the end close to the first blocking member 410 to the end away from the first blocking member 410.

[0118] In the embodiment, the filtering member 340 is made by bending a filter plate into a cylindrical shape, but is not limited thereto.

[0119] The working principle of the intelligent water meter based on hydroelectric power generation provided in the embodiment is as follows.

[0120] In the normal working state (i.e., the state of normally performing the filtering work), the control core 400 is located at the first sliding stop point.

[0121] At this time, the first communication hole 331 is in an open state, the blowdown port 312 is in a closed state, and the second communication hole 391 is in an open state.

[0122] When the control core 400 is located at the first sliding stop point, we take the state that the piston 384 is in contact with the first stop flange 382 as the initial state, as shown in Figure 2 .

[0123] In this state, the water in the water supply pipeline 1000 enters the shunt inner cavity 311 of the shunt box 310 through the input pipe 360, and the water in the shunt inner cavity 311 passes through the filtering member 340 to enter the columnar space surrounded by the filtering member 340, and then enters the flow guide pipe 320 through the first communication hole 331, and finally enters the output pipe 370 from the flow guide pipe 320 to leave the shunt box 310, so that the filtering of the water in the water supply pipeline 1000 is completed.

[0124] The filtered water enters the pipeline water flow power generation module 200 to drive the pipeline water flow power generation module 200 to generate power. The water flowing out of the pipeline water flow power generation module 200 enters the water meter body 100 and finally flows out from the water outlet of the water meter body 100.

[0125] In this state, the filtering mechanism 300 continuously filters the water, and the pipeline water flow power generation module 200 continuously generates power to charge the energy storage module.

[0126] When the filtering mechanism 300 continuously operates for a period of time (which can be set according to actual conditions), the controller of the control module issues an instruction to the driver according to the preset time interval to control the driver to drive the control core 400, so that the control core 400 moves from the first sliding stop point to the second sliding stop point.

[0127] When the control core 400 is located at the second sliding stop point, the first communication hole 331 is closed by the first blocking member 410, the blowdown port 312 is opened, and the second communication hole 391 is closed by the third blocking member 430, as shown inFigure 4 As shown.

[0128] At this time, the water in the diversion cavity 311 will not continue to pass through the filter element 340, and the water flow to the pipeline water flow power generation module 200 is temporarily interrupted. The water in the diversion cavity 311 directly enters the first drain pipe 380 through the drain outlet 312.

[0129] During this process, the water flow in the diversion cavity 311 can wash away the impurities filtered out by the filter element 340 from the outside of the filter element 340, and discharge these impurities into the first drain pipe 380 through the drain port 312, thereby achieving the washing of the filter element 340.

[0130] After the sewage enters the first drain pipe 380, under the action of water pressure, the sewage pushes the piston 384 to slide towards the second stop flange 383, as... Figure 5 As shown. Until the piston 384 abuts against the second stop flange 383, at this point, the surface of the piston 384 near the drive rod 385 is in contact with the surface of the second stop flange 383 near the first stop flange 382, ​​as shown. Figure 6 As shown.

[0131] When the piston 384 is about to abut against the second stop flange 383, that is, when the surface of the piston 384 near the drive rod 385 is about to come into contact with the surface of the second stop flange 383 near the first stop flange 382, ​​the surface of the piston 384 near the drive rod 385 will first come into contact with the surface of the end block 450 near the extension rod 440. This allows the piston 384 to push the end block 450 to move. In this way, the end block 450 can drive the control core 400 through the extension rod 440, thereby allowing the piston 384 to indirectly drive the control core 400 to move from the second sliding stop to the first sliding stop. When the piston 384 abuts against the second stop flange 383, the surface of the end block 450 near the extension rod 440 is in contact with the surface of the second stop flange 383 near the first stop flange 382. At this time, the surface of the end block 450 near the extension rod 440 and the surface of the second stop flange 383 near the first stop flange 382 are essentially on the same plane, and the control core 400 is driven back to the first sliding stop by the piston 384.

[0132] After the control core 400 returns to the first sliding stop, the first connecting hole 331 is in the open state, the drain port 312 is in the closed state, and the second connecting hole 391 is in the open state.

[0133] At this time, the filtering mechanism 300 can continue to filter water, and the pipeline water flow power generation module 200 can continue to generate electricity to charge the energy storage module. At the same time, since the second communication hole 391 is opened, under the action of the elastic member, the piston 384 is pushed to the first stop flange 382 again, and the sewage in the first sewage pipe 380 is pushed into the second sewage pipe 390 from the second communication hole 391 and discharged.

[0134] The second sewage pipe 390 is used to communicate with the sewage pipe to complete sewage discharge.

[0135] When the piston 384 is recombined with the first stop flange 382, the sewage is discharged. At this time, it is returned to the state as shown in Figure 2 .

[0136] It should be noted that, in the process of movement of the piston 384 to the second stop flange 383 (sewage enters the first sewage pipe 380), the drive rod 385 drives the air cylinder to inhale. When the piston 384 moves to the first stop flange 382 again (sewage is discharged to the second sewage pipe 390), the drive rod 385 drives the air cylinder to inflate the first sewage pipe 380 through the inflation pipe 386, so that the impurities in the first sewage pipe 380 can be fully stirred by the bubbles, and the impurities can be discharged into the second sewage pipe 390 with the water flow as much as possible, and the residues and deposits of the impurities in the first sewage pipe 380 are reduced as much as possible, and the self-cleaning of the first sewage pipe 380 is realized.

[0137] Subsequently, the above steps are repeated to realize repeated self-cleaning, and details are not described herein.

[0138] The beneficial effects of the intelligent water meter based on hydroelectric power provided by the embodiment of the application include but are not limited to the following points.

[0139] The dependence on external power supply is effectively reduced, and the frequency of manual maintenance is reduced, so that the long-term stable operation of the water meter can be guaranteed, and the influence of power failure on the operation of the water meter is reduced.

[0140] Self-cleaning of the filtering mechanism 300 can be realized.

[0141] When the filtering mechanism 300 is self-cleaned, the control core 400 is driven only once by the driver, that is, the control core 400 is driven from the first sliding stop point to the second sliding stop point, so that the self-cleaning and the reset of the control core 400 are automatically completed, which is more power-saving, and more sufficient power can be reserved for the electric meter body.

[0142] When the driver drives the control core 400, that is, after the driver drives the control core 400 from the first sliding stop point to the second sliding stop point, even if the electric energy in the energy storage module is insufficient, the control core 400 can automatically reset by using the water pressure in the water supply pipeline 1000, so as to continue to normally generate electricity by using the pipeline water flow power generation module 200, and too much water cannot enter the sewage pipeline, waste of water resources is avoided, and automatic resetting of the control core 400 in the case of no power supply is realized.

[0143] The distance between the first stop flange 382 and the second stop flange 383 determines the movable distance of the piston 384 during self-cleaning, so that the water consumption of each self-cleaning can be controlled, the flushing water can be accurately controlled, and water resources can be more saved.

[0144] The first sewage pipe 380 can effectively reduce the residue and deposition of impurities.

[0145] In summary, the intelligent water meter based on hydroelectric power generation provided by the embodiment of the application effectively reduces the dependence on external power supply, reduces the frequency of manual maintenance, can guarantee long-term stable operation of the water meter, and reduces the influence of power failure on operation of the water meter.

[0146] The above only describes the preferred embodiments of the application and is not used to limit the application. For those skilled in the art, the application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the application shall be included in the protection scope of the application.
